Detailed Description of the Presently Preferred Exemplary Embodiments

[0031] For the purpose of this specification, the expandable knee sections according to exemplary embodiments hereof will be primarily described in relation to their use and utility with pants. However, it will be understood by a person of ordinary skill in the art, upon reading this description, that the expandable knee sections may also be used with other types of garments such as jumpers, one-piece suits, or any other type of garments that have a knee and may utilize a knee patch. It is understood that the scope of the exemplary embodiments described herein are not in any way limited by the type of garment that may include the expandable knee sections.

[0032] FIGS. 1A and IB show a pair of pants 110 viewed from the front and the back respectively, and incorporating expandable knee sections 112-1 and 112-2 (collectively and individually 112) according to exemplary embodiments hereof. In some embodiments, a knee section 112-1 may be generally configured with the right leg 114, and a knee section 112-2 may be generally configured with the left leg 116. Note that for the purposes of this specification, the term“right” and“left” ( e.g ., right leg and left leg) will refer to the directions right and left from the perspective of the person wearing the garment.

[0033] As is known in the art, the legs 114, 116 are portions of the pants 110 that may partially or wholly cover the legs of a person wearing the pants. The right and left legs 114, 116 may be generally configured with the waistband 118. The right leg 114 may be generally configured with the right portion 119 of the waistband 118, and the left leg 116 may be generally configured with the left portion 120 of the waistband 118. In this way, the right and left legs of a person wearing the pants may pass through the right and left waist portions 119, 120 and into the right and left legs 114, 116 respectively.

[0034] Knee sections 112 may be incorporated or otherwise configured with the legs 114,

116 in a number of ways. For example, the legs 114, 116 may be constructed or otherwise formed of different sections, elements or pieces depending on how the knee sections 112 may be configured.

[0035] Accordingly, aspects of the expandable knee sections 112, the legs 114, 116 and the pants 110 will be described by way of several detailed examples. The examples provided below are chosen to illustrate different configurations, types or combinations of expandable knee sections 112, legs 114, 116 and pants 110. Those of ordinary skill in the art will appreciate and understand, upon reading this description, that the examples are not limiting and that the knee sections 112, the legs 114, 116 and the pants 110 may be constructed, made or otherwise formed in the ways described in the examples, in different ways, or in any combination thereof.

[0036] In one example, the expandable knee sections 112 may be formed as substantially straight sections that may encircle the legs 114, 116 as shown, e.g., in FIGS. 1A and IB. In these cases, the expandable knee sections 112 may cover both the front and the back of the legs 114, 116

[0037] In other examples, the expandable knee sections 112 may be formed as different shaped sections that may cover a portion of the front of the legs 114, 116 but not necessarily a portion or an entire portion of the backs of the legs 114, 116. For instance, the expandable knee sections 112 may be circular or oval shaped sections 112-1' and 112-2' that may cover a portion of the front of the legs 114, 116 as shown in FIG. 2A, but not necessarily the back of the legs 114, 116 as shown in FIG. 2B. The expandable knee sections 112 may also be square or generally rectangular shaped sections 112-1" and 112-2" that may cover a portion of the front of the legs 114, 116 as shown in FIG. 3B, but not necessarily the back of the legs 114, 116 as shown in FIG 3B.

[0038] In another example, the expandable knee sections 112 may be different formed shapes that may cover a portion of the front of the legs 114, 116 and a portion of the back of the legs 114, 116. In this example, the knee sections 112 may not necessarily extend the full width of the back of the legs. This is shown, e.g., in FIGS. 4A and 4B where the knee sections 112-1'" and 112-2'" may be diamond shaped with a portion of the knee sections 112 extending from the front of the legs 114, 116 to the back of the legs 114, 116, but not necessarily extending across the entire width of the back of the legs 114, 116. Note that other shaped knee sections 112 may also be used in this type of configuration and are contemplated herein.

[0039] As should be clear to a person of ordinary skill in the art, upon reading this description, any and all possible shapes or forms, or combinations of shapes or forms, of knee sections 112 are contemplated within this disclosure. The edges of the knee sections 112 may be straight, curved, smooth or any combination thereof, and may include curvatures, patterns or other elements. One or both legs 114, 116 may have knee sections 112, and the knee section 112 on the right leg 114 need not match the knee section 112 on the left leg 116. The knee sections 112 may be configured with the pants 110 (or other types of garments) using any method, including the methods described in the examples below, combinations of the methods described in the examples below, and/or using any other methods or combinations of any other methods.

[0040] Note that this specification may sometimes describe aspects of the legs 114, 116 with reference to figures that may show both legs 114, 116, or only leg 114 and/or only leg 116. In the cases where the aspects of the legs 114, 116 are described with reference to one or more figures that only depict one of the legs 114, 116, it is understood that the aspects described with reference to the shown leg also pertain to the leg that may not be shown in the figure(s).

[0041] As described in more detail below, knee sections 112 according to exemplary embodiments hereof may have stretch and/or recovery properties other than those of the rest of the leg material.

[0042] In addition to (or instead of) the stretch and recovery properties, a knee section

112 according to exemplary embodiments hereof may be formed using a material and/or fabric that is stronger or thicker than the underlying garment material and/or fabric (i.e., than the material and/or fabric used to make the garment). The added strength or thickness may be achieved by using more yarn (per unit area) in the material and/or fabric of the knee section(s) 112 than in the material and/or fabric used for rest of the leg or least than in surrounding parts of the leg. For example, in some embodiments, a minimum of about five percent (5%) more yarn (per unit area) may be used in the knee section(s) 112. In some other embodiments up to about 15 percent or 16 percent or even 20 percent more yam (per unit area) may be used in the material and/or fabric of the knee section(s) 112 than in the rest of the leg.

[0043] When a material has multiple layers, additional strength in the material may be achieved by one or more of the layers having more yarn per unit area. When a material is formed with a fabric and a fusible substrate, the additional strength may be achieved by the fabric having more yarn per unit area.

[0044] While the knee section(s) may be strengthened by using more yarn per unit area, they may also (instead or in addition) be strengthened in other ways, for example, by adding an extra layer of fusible.

[0045] Those of ordinary skill in the art will appreciate and understand, upon reading this description, that the amount (if any) of extra yarn per unit area used in the knee section may depend on factors such as the intended use of the garment and the type and/or strength of the underlying garment or leg fabric.

Examples

[0046] The following are non-limiting examples of exemplary embodiments hereof.

These examples are not intended to be mutually exclusive.

Example 1

[0047] Exemplary embodiments are shown in FIGS. 1A and IB, where FIG. IB shows the pants 110 of FIG. 1A viewed from the back. The right leg 114 may generally comprise an upper leg section 114-1, a knee section 112-1 and a lower leg section 114-2. The upper leg section 114-1 may be attached to the waist 118, e.g., by being sewn along the lines D-D' and D-I, and to the knee section 112-1, e.g, by being sewn along the line C-C' (front and back). The knee section 112-1 may be attached to the lower leg section 114-2, e.g, by being sewn along the line B-B' (front and back).

[0048] The left leg 116 may generally comprise an upper leg section 116-1, a knee section 112-2 and a lower leg section 116-2. The upper leg section 116-1 may be attached to the waist 118, e.g, by being sewn along the line H-H’ and H-I, and to the knee section 112-2, e.g, by being sewn along the line G-G’ (front and back). The knee section 112-2 may be attached to the lower leg section 116-2, e.g, by being sewn along the line F-F’ (front and back).

[0049] FIG. 5 shows an exploded view of the pants 110 of FIG. 1A. [0050] As is shown in this example, the knee sections 112-1, 112-2 may encircle the right and left legs, when worn, preferably in the general area of the right and left knees respectively. This is shown in FIGS. 1A and IB where the knee sections 112-1, 112-2 may extend across the fronts of the legs 114, 116 (FIG. 1A) and across the backs of the legs 114, 116 (FIG. IB)

[0051] As shown in FIGS. 6A and 6B, the right lower leg section 114-2, the right knee section 112-1 and the right upper leg section 114-1 may each comprise a piece of fabric

(FIG. 6A), and the corresponding upper and lower edges of the pieces may be generally stitched together to form a combined right leg piece 114A (FIG. 6B). That is, the upper edge of the piece that may form the lower leg section 114-2 may be generally aligned with the lower edge of the piece that may form the knee section 112-1, and the upper edge of the piece that may form the knee section 112-1 may be generally aligned with the lower edge that may form the upper leg section 114-1. The lower leg section 114-2 may then be attached to the knee section 112-1, e.g., by being sewn along the line B'-B-B' as shown in FIG. 6B, and the knee section 112-1 may be attached to the upper leg section 114-1, e.g, by being sewn along the line C'-C-C' as shown in FIG. 6B. The combined pieces may generally form a combined leg piece 114A.

[0052] To form the right leg 114 from the combined right leg piece 114A, the combined leg piece 114A may be generally formed into a closed loop, e.g, by folding the piece 114A along the lines A-B-C-D to form an inner area 122, and stitching the edges together along the lines A'-B'-C'-D'. This may form the leg 114 in FIG. 1A with a side stitch along the line

A'-B'-C'-D', and the line A-B-C-D generally forming a fold line.

[0053] FIG. 7 shows the resulting cross-sectional shape of the leg 114 taken along the cut line J-J in FIG. 1A. As shown, the cross-sectional shape of the leg 114 may be represented as generally circular with an inner area 122 through which the leg of a person wearing the pants 110 may be received. It is appreciated that the leg 116, although not shown in this

representation, may have the same or similar cross-sectional shape and a same or similar inner area 122. Note that the circular cross-sectional shape depicted in FIG. 7 is meant for conceptual purposes and the cross-sectional shape of the legs 114, 116 may take any shape, as the legs 114, 116 may comprise flexible material. It should also be noted that the legs 114, 116 may include openings, gaps, cut-outs, sections and other elements along their fronts, backs, sides, surfaces and/or in any other location or area such that the legs 114, 116 may not cover the entire circumference of the person’s legs when worn. However, it is understood by a person of ordinary skill in the art that the elements and formations of the garment’s legs 114, 116 and the amount of the circumference of a person’s legs covered by the garment’s legs 114, 116 and/or by the knee sections 112, when worn, in any area of the leg, do not limit the scope of the exemplary embodiments described herein in any way. [0054] While not shown, it is understood that the left leg 116 may be similarly formed as described above with respect to the right leg 114, but using pieces that may form the left lower leg 116-2, the left knee section 112-2 and the left upper leg section 116-1. The upper edge of the piece that may form the left lower leg section 116-2 may be generally aligned with the lower edge of the piece that may form the left knee section 112-2, and the upper edge of the piece that may form the left knee section 112-2 may be generally aligned with the lower edge that may form the left upper leg section 116-1. The lower leg section 116-2 may then be attached to the knee section 112-2, e.g., by being sewn along the line F'-F-F', and the knee section 112-2 may be attached to the upper leg section 116-1, e.g, by being sewn along the line G'-G-G'. The combined pieces may generally form a combined leg piece 116A.

[0055] To form the left leg 116 from the combined left leg piece 116A, the combined leg piece 116A may be generally formed into a loop, e.g, by folding the piece 116A along the lines E-F-G-H to form an inner area 122, and stitching the edges together along the lines E'-F'-G'-H'. This may form the left leg 116 in FIG. 1A with a side stitch along the line E'-F'-G'-H', and the line E-F-G-H generally forming a fold line.

[0056] Note that the steps by which the segments and pieces may be formed, folded, stitched, aligned and attached may be performed in any appropriate order. For example, the piece that may form the lower leg section 114-2 may be formed into a loop, e.g, by folding the section 114-2 along the line A-B, and stitched along the lines A'-B'. The piece that may form the knee section 112-1 may be formed into a loop, e.g, by folding the section 112-1 along the line B-C, and stitched along the lines B'-C'. And the piece that may form the upper pants section 114-1 may be formed into a loop, e.g, folding the section 114-1 along the line C-D, and stitched along the lines C'-D'. This may form the sections 114-2, 112-1 and 114-1 respectively as shown in FIG. 5. The upper edge of the lower leg section 114-2 may be attached to the lower edge of the knee section 112-1, and the upper edge of the knee section 112-1 may be attached to the lower edge of the upper leg section 114-1 to generally form the leg 114 with an inner area 122. The leg 114 may be attached to the pants waist 118 to form the right side portion of the pants 110 of FIG. 1A.

Example 2

[0057] In some exemplary embodiments hereof, the knee sections 112-1, 112-2 may partially encircle the right and left legs when worn, preferably in the general area of the right and left knees, respectively. In one example of this type, the knee sections 112-1, 112-2 may generally extend across the width of the front of the legs 114, 116, respectively (e.g, as depicted in FIG. 8A), but not across the width of the back of the legs 114, 116 respectively (as depicted in FIG. 8B). In this case, the lower leg sections 114-2, 116-2 may be partial lower leg sections 114-2', 116-2', the knee sections 112-1, 112-2 may be partial knee sections 112-1', 112-2', and the upper leg sections 114-1, 116-1 may be a partial upper leg section 114-1', 116-1'. As shown in FIG. 8A, the right partial sections 114-2', 112-1', 114-1' may each generally extend across the front width of the leg 114, and the left partial sections 116-2', 112-2', 116-1' may each generally extend across the front width of the leg 116.

[0058] As shown in FIG. 8B, the leg 114 may also include a partial length section 114-4 that may generally extend across the width of the leg 114 that the partial sections 114-2', 112-1', 114-1' may not extend (e.g., the back of the leg in FIG. 8B). The leg 116 may also include a partial length section 116-4 that may generally extend across the width of the leg 116 that the partial sections 116-2', 112-2', 116-1' may not extend (e.g, the back of the leg in FIG. 8B).

[0059] As shown in FIG. 9A, the upper edge of the piece that may form the partial lower leg section 114-2' may be generally aligned with the lower edge of the piece that may form the partial knee section 112-1', and the upper edge of the piece that may form the partial knee section 112-1' may be generally aligned with the lower edge of the piece that may form the partial upper leg section 114-1'. The partial lower leg section 114-2' may then be attached to the partial knee section 112-1', e.g, by being sewn along the line B'-B, and the partial knee section 112-1' may be attached to the partial upper leg section 114-1', e.g, by being sewn along the line C'-C. The combined partial sections 114-2', 112-1', 114-1' may be aligned with and attached to the partial length section 114-4, e.g, by being sewn along the line A-B-C-D. This may form the leg piece 114B shown in FIG. 9B. Note that the steps taken to generally align and attach the segments and pieces together may be performed in any adequate order.

[0060] To form the left leg 116 from the right leg piece 116B, the leg piece 116B may be generally formed into a loop, e.g, by folding the piece 116B along the lines A-B-C-D to form an inner area 122, and stitching the edges together along the lines A'-B'-C'-D'. This may form the leg 116 with a side stitch along the line A'-B'-C'-D', and a side stitch along the line A-B-C-D. The line A-B-C-D may also generally form a fold line.

[0061] The resulting cross-sectional shape of the leg 114 taken along cut line K-K in

FIG. 8A is shown in FIG. 110. As seen, the cross-section may include the partial knee section 112-1', a partial length section 114-4 and an inner area 122. The aspects described above with reference to FIG. 7 and the cross-section of the leg 114 and the knee section 112-1 may also apply to the cross-section depicted in FIG. 110.

[0062] It is understood that a left leg piece 16B may be similarly formed by aligning and attaching partial lower leg sections 116-2', 112-2', 116-1', and aligning and attaching the resulting combined section with a partial length section 116-4. The left leg 116 may be formed from the leg piece 116B as described above with relation to forming the right leg 114 from the right leg piece 114B. Example 3

[0063] In other exemplary embodiments hereof, with reference to FIGS. 11A and 11B, the legs 114, 116 may include cutout regions 114-5, 116-5, respectively, that may each include a cutout region 124. The cutout regions 124 may generally extend across the front width of the legs 114, 116 (FIG. 11A) but not the back (FIG. 11B), when worn. The knee sections 112-1' and 112-2' may be received into and configured within the cutout regions 124. In this way, the pant legs 114, 116 may include front knee sections 112-1', 112-2', when worn.

[0064] As shown in FIGS. 12A and 12B, the cutout section 114-5 may include a cutout region 124 defined by the lines C'-C, C-B, and B-B'. Note that in this example the cutout region 124 may have an open end at B'-C' but this may not be necessary, and the side of the cutout piece defined by B'-C' may not be open (as described in other examples herein). Although shown in the drawings in FIGS. 12A and 12B as rectangular in shape, it should be appreciated that the cutout region 124 and corresponding knee sections 112-1' may be other shapes (e.g., oval, semi oval, circular, semicircular, diamond, trapezoid, triangular, etc.). It may be preferable that the cutout region 124 includes a shape and dimensions that may generally correspond to the shape and dimensions of the partial knee section 112-1' so that the cutout region 124 may receive the knee section 112-1'. The knee section 112-1' may be generally overlaid with or on the cutout region 124 such that the outer edges of the knee section 112-1' may generally align with the edges that define the cutout region (e.g., defined by the lines C'-C, C-B, and B-B').

The outer edges of the knee section 112-1' may then be attached to the edges that define the cutout, e.g, by stitching along the lines C'-C, C-B, and B-B', to form the leg piece 114C of FIG. 12B.

[0065] It may be preferable that the knee section 112-1' be configured within the cutout region 124 as described above such that there are no gaps, holes, spaces or disjoints between the knee section 112-1' and the edges that define the cutout region 124 (e.g, along the lines C'-C, C-B, and B-B'). In this way, the leg piece 114C may be free of unwanted holes or gaps. This may improve the strength of the leg piece 114C in the area of the knee section 112-1'. Note however, that this may not be necessary.

[0066] To form the right leg 114 from the right leg piece 114C, the leg piece 114C may be generally formed into a loop, e.g, by folding the piece 114C along the lines A-B-C-D to form an inner area 122, and stitching the edges together along the lines A'-B'-C'-D'. This may form the leg 114 with a side stitch along the line A'-B'-C'-D', and the line A-B-C-D generally forming a fold line.

[0067] It is understood that a left leg piece 116C may be similarly formed by overlaying a piece that may form a partial knee section 112-2' with a cutout piece 116-5 that may include a cutout region 124. The shape and dimensions of the partial knee section 112-2' may generally correspond to the shape and dimensions of the cutout region 124, so that the knee section 112-2' may be received by the cutout region 124. The outer edges of the knee section 112-2' may be attached to the edges that define the cutout region 124, e.g., by stitching along the junction of the edges, and a leg piece 116C may be formed. The left leg 116 may be formed from the leg piece 116C as described above with relation to forming the right leg 114 from the right leg piece

114C.

Example 4

[0068] In other exemplary embodiments that may expand upon the prior exemplary embodiments of FIGS. 11 A, 11B, 12A and 12B (Example 3, above), the partial knee sections 112-1' and 112-2' may not extend the full front width of the legs 114, 116, respectively as shown, e.g, in FIG. 13A. In this case, the cutout section 114-5 may include a cutout region 124 that may not extend to the right edge B'-C' or to the middle line B-C as generally described in the embodiment of FIG. 12A, but instead, the cutout region 124 may be positioned in an intermediary position between the right edge B'-C' on the right and the left edge B'-C on the left. The cutout region 124 may preferably be positioned in an intermediary position that may be between the right edge B'-C on the right and the middle line B-C. This is depicted in

FIG. 14A.

[0069] As with the prior example of FIG. 10A and 10B, the knee section 112-1' of

FIG. 14A may be generally aligned with and configured within the cutout region 124, e.g, by stitching along junctions between the outer edges of the knee section 112-1' and the edges that define the cutout region 124. This may result in the leg piece 114C of FIG. 14B.

[0070] Although shown in the drawings in FIGS. 13A, 14A and 14B as rectangular in shape, it should be appreciated that the cutout region 124 and corresponding knee sections 112- V in embodiments corresponding to this example may be other shapes (e.g., oval, semi oval, circular, semicircular, diamond, trapezoid, triangular, etc.). It may be preferable that the cutout region 124 includes a shape and dimensions that may generally correspond to the shape and dimensions of the partial knee section 112-1’ so that the cutout region 124 may receive the knee section 112-1’.

[0071] To form the right leg 114 from the right leg piece 114C, the leg piece 114C may be generally formed into a loop, e.g, by folding the piece 114C along the lines A-B-C-D to form an inner area 122, and stitching the edges together along the lines A'-B'-C'-D'. This may form the leg 114 with a side stitch along the line A'-B'-C'-D', and the line A-B-C-D generally forming a fold line.

[0072] It is understood that a left leg piece 116C may be similarly formed by overlaying a piece that may form a partial knee section 112-2' with a cutout piece 116-5 that may include a cutout region 124. The shape and dimensions of the partial knee section 112-2' may generally correspond to the shape and dimensions of the cutout region 124 so that the knee section 112-2' may be received by the cutout region 124. The outer edges of the knee section 112-2' may be attached to the edges that define the cutout region 124, e.g., by stitching along the junctions of the edges, and a leg piece 116C may be formed. The left leg 116 may be formed from the leg piece 116C as described above with relation to forming the right leg 114 from the right leg piece 114C.

[0073] While FIGS. 14A and 14B may depict the leg 114 and the leg piece 114C as including one cutout region 124, the leg 114 and the resulting leg piece 114C may include more than one cutout region 124. In this scenario, each cutout region 124 may be configured with a knee section 112-1' as described above. In addition, more than one knee section 112-1' may be configured with one, more than one, or each cutout region 124.

Example 5

[0074] In other exemplary embodiments hereof, that may expand upon the embodiments described in Examples 2 and 4, the legs 114, 116 may include partial length sections 114-4’, 116-4’ respectively, and cutout sections 114-5’, 116-5’ respectively.

[0075] As shown in FIG. 15A, the cutout section 114-5’ of the right leg 114 may generally form the front of the leg 114, and the cutout section 116-5’ of the left leg 116 may generally form the front of the leg 116. As shown in FIG. 15B, the partial length section 114-4’ may generally form the back of the leg 114, and the partial length section 116-4’ may generally form the back of the leg 116.

[0076] As shown in FIG. 16A, the cutout section 114-5’ may include a cutout 126 the may be formed and generally located in the knee region of leg 114, when worn. As shown, the cutout 126 may preferably be located in an intermediary area between the left edge generally defined by the line B'-C' and the right edge generally defined by the line B-C. Although shown in the drawings in FIGS. 15A, 16A and 16B as rectangular in shape, it should be appreciated that the cutout region 124 and corresponding knee sections 112-T may be other shapes (e.g., oval, semi oval, circular, semicircular, diamond, trapezoid, triangular, etc.).

[0077] It may be preferable that the cutout region 124 includes a shape and dimensions that may generally correspond to the shape and dimensions of the partial knee section 112-1' so that the cutout region 124 may receive the knee section 112-1'. The knee section 112-1' may be generally overlaid with or positioned on the cutout region 124 such that the outer edges of the knee section 112-1' may generally align with the edges that define the cutout region. The outer edges of the knee section 112-1' may then be attached to the edges that define the cutout, e.g, by stitching along the junctions of the knee section 112-1' and the cutout 126.

[0078] The cutout section 114-5’ may be aligned with and attached to the partial length section 114-4’, e.g., by being sewn along the line A-B-C-D. This may form the leg piece 114D shown in FIG. 16B. Note that the steps taken to generally align and attach the segments and pieces together may be performed in any adequate order.

[0079] It may be preferable that the knee section 112-1' may be configured within the cutout region 124 as described above such that there are no gaps, holes, spaces or disjoints between the knee section 112-1' and the edges that define the cutout region 124. In this way, the leg piece 114D may be free of unwanted holes or gaps. This may improve the strength of the leg piece 114D in the area of the knee section 112-1'. Note however, that this may not be necessary.

[0080] To form the right leg 114 from the right leg piece 114D, the leg piece 114D may be generally formed into a loop, e.g., by folding the piece 114D along the lines A-B-C-D to form an inner area 122, and stitching the edges together along the lines A'-B'-C'-D'. This may form the leg 114 with a side stitch along the line A'-B'-C'-D', and the stitch line A-B-C-D generally forming a fold line.

[0081] It is understood that a left leg piece 116D may be similarly formed by overlaying a piece that may form a partial knee section 112-2' with a cutout piece 116-5’ that may include a cutout region 124. The shape and dimensions of the partial knee section 112-2' may generally correspond to the shape and dimensions of the cutout region 124 so that the knee section 112-2' may be received by the cutout region 124. The outer edges of the knee section 112-2' may be attached to the edges that define the cutout region 124, e.g, by stitching along the junction of the edges. The cutout section 116-5' may be aligned with and attached to the partial length section 116-4', e.g, by being sewn along the line A-B-C-D. This may form the leg piece 16D. Note that the steps taken to generally align and attach the segments and pieces together may be performed in any adequate order. The left leg 116 may be formed from the leg piece 116D as described above with relation to forming the right leg 114 from the right leg piece 114D.

Example 6

[0082] In other exemplary embodiments, the knee section 112-1 and the leg 114 may each be formed of a piece of fabric as shown in FIG. 17A. The knee section 112-1 may be overlaid onto (and/or underlaid on) the leg 114 in the area of the knee region of the leg (e.g, along the lines C'-C-C, C'-B', B'-B-B' and B'-C) and attached thereto as shown in FIG. 17B, e.g, by sewing along the lines B'-B-B' and C'-C-C. This may form the leg piece 114E of

FIG. 17B. Note that the area of the leg piece 114E that may include the knee section 112-1 may include at least two layers, e.g, one layer that may include the knee section 112-1 and one layer that may include the underlying piece of fabric that may form the underlying leg 114. In this example, the knee section 112-1 may generally extend across the entire width of the leg 114 piece 114E.

[0083] To form the right leg 114 from the right leg piece 114E, the leg piece 114E may be generally formed into a loop, e.g, by folding the piece 114E along the lines A-B-C-D to form an inner area 122, and stitching the edges together along the lines A'-B'-C'-D'. This may form the leg 114 with a side stitch along the line A'-B'-C'-D', and the line A-B-C-D generally forming a fold line.

[0084] Although shown in the drawings in FIGS. 17A and 17B as rectangular in shape, it should be appreciated that the knee sections 112-1’ in embodiments corresponding to this example may be other shapes ( e.g ., oval, semi-oval, circular, semi-circular, diamond, trapezoid, triangular, etc.).

[0085] As will be described in more detail below, the underlying fabric that may form the leg 114 may include both stretch and recovery properties, and the knee sections 112 may provide both stretch and recovery properties. The underlying pant fabric may be cut on the bias, or may be compacted to give it stretch properties, and then combined with the knee sections 112 to control and give memory to the stretch imposed by the bias cut and/or the compaction. In this case, it may be preferable for the knee sections 112 to be fused with the compacted leg fabric to form the leg piece 114E in order to best provide memory and recovery to the leg piece 114E in the area of the knee section 112.

[0086] It is understood that a left leg piece 116E may be formed as described above in relation to the right leg piece 114E, and the left leg 116 may be formed from the left leg piece 116E as describe above in relation to forming the right leg 114 from the right leg piece 114E.

Example 7

[0087] In other exemplary embodiments hereof, that expand upon the embodiments of

FIGS. 17A and 17B, the piece(s) of fabric that may form the knee section 112-1 in FIG. 17A may not extend the full width of the piece(s) of fabric that may form the underlying leg 114. Instead, as shown in FIGS. 18A and 18B, the knee section 112-1 may be a partial knee section 112-1' that may only extend over a portion (less than the entire leg) of the width of the leg 114, as shown, e.g., in FIGS. 18A-18B. The partial knee section 112-1' may be overlaid (and/or underlaid) on the leg 114 in the area of the knee region of the leg, e.g., along the lines C'-C-C and B'-B-B' in FIG. 18A, and attached thereto as shown in FIG. 18B, e.g, by stitching along the outer edges of the knee section 112-1'. FIG. 18B shows the knee section 112-1' as being located in an intermediary position between the right edge and the left edge of the leg piece

114G. The knee section 112-1' may preferably be positioned in an intermediary position that may be between the left edge B'-C' on the left and the middle line B-C. This is depicted in

FIG. 19B. It is clear that the knee section 112-1' may be located in any position with respect to the leg piece 114F.

[0088] To form the right leg 114 from the right leg piece 114F, the leg piece 114C may be generally formed into a loop, e.g, by folding the piece 114F along the lines A-B-C-D to form an inner area 122, and stitching the edges together along the lines A'-B'-C'-D'. This may form the leg 114 with a side stitch along the line A'-B'-C'-D', and the line A-B-C-D generally forming a fold line.

[0089] As will be described in more detail below, the underlying fabric that may form the leg 114 may include stretch properties, and the overlaid (and/or underlaid) knee sections 112 may provide recovery properties. The underlying pants fabric may be cut on the bias, or may be compacted to give it stretch properties, and then combined with the knee sections 112 to control and give memory to the stretch imposed by the bias cut and/or the compaction. In this case, it may be preferable for the knee sections 112 to be fused with the compacted leg fabric to form the leg pieces 114F in order to best provide memory and recovery to the leg piece 114F in the area of the knee section 112.

[0090] Although shown in the drawings in FIGS. 18A and 18B as rectangular in shape, it should be appreciated that the knee section 112-1' in embodiments corresponding to this example may be other shapes (e.g., oval, semi oval, circular, semi circular, diamond, trapezoid, triangular, etc.).

[0091] As appreciated, a left leg piece 116F may be formed as described above in relation to the right leg piece 114F, and the left leg 116 may be formed from the left leg piece 116F as describe above in relation to forming the right leg 114 from the right leg piece 114F.

[0092] In the embodiments described with reference to FIGS. 17A, 17B, 18A and 18B, it may be preferable that with the legs 114, 116 attached to the pants body of the pants, that the knee sections 112-1 and 112-2 (FIG. 11B), and 112-1' and 112-2' (FIG. 12B) be located on the outside layer of the legs 114, 116 respectively (e.g., with the knee sections 112-1, 112-2 and/or 112-1', 112-2' facing outward away from the legs, when worn). In this way, the knee sections 112-1, 112-2, 112-1' and 112-2' may provide additional ruggedness, durability, protection, reinforcement, thickness and strength to the legs 114, 116 in the area of the knee sections 112-1, 112-2, 112-1' and 112-2' respectively. The knee sections 112-1, 112-2, 112-1' and 112-2' may also provide stretch and recovery to the legs 114, 116 in the area of the knee sections 112-1, 112-2, 112-1' and 112-2' respectively as will be described below. Note also that the knee sections 112-1, 112-2, 112-1 and 112-2' may also be located on an inner layer of the legs 114, 116, e.g, facing towards the legs, when worn, in an intermediate layer or in any combination of layers thereof.

Example 8

[0093] In other exemplary embodiments hereof, the underlying pant sections 114, 116 of the embodiments described in relation to FIGS. 17A and 17B (Example 6) and/or FIGS. 18A and 18B (Example 7) may be formed by joining front partial length sections 114-6, 116-6 with back partial length sections 114-4, 116-4 respectively. An example of this is shown in

FIGS. 19A and 19B for the case of partial knee sections 112-1'. Note that the details of this example may also apply to the case of other types of knee sections such as full-width knee sections 112-1.

[0094] The knee section 112-1' may be overlaid (and/or underlaid) on the front partial length section 114-6 in the area of the knee region of the leg, e.g., along the lines C-C and B-B' in FIG. 19A, and attached thereto as shown in FIG. 19B, e.g, by stitching along the outer edges of the knee section 112-1'. FIG. 18B shows the knee section 112-1' as being located in an intermediary position between the left edge and the right edge of the leg piece 114G. In a preferably embodiment, the knee section 112-1' may be positioned in an intermediary position that may be between the left edge B'-C' on the left and the middle line B-C. This is depicted in FIG. 19B. Those of ordinary skill in the art will appreciate and understand, upon reading this description, that the knee section 112-1' may be located in any position with respect to the leg piece 114F.

[0095] To form the right leg 114 from the right leg piece 114F, the leg piece 114C may be generally formed into a loop, e.g, by folding the piece 114F along the lines A-B-C-D to form an inner area 122, and stitching the edges together along the lines A'-B'-C'-D'. This may form the leg 114 with a side stitch along the line A'-B'-C'-D', and the line A-B-C-D generally forming a fold line.

[0096] Although shown in the drawings in FIGS. 19A and 19B as rectangular in shape, it should be appreciated that the knee sections 112-1’ in embodiments corresponding to this example may be other shapes (e.g, oval, semi-oval, circular, diamond, trapezoid, triangular, etc.).

End of Example 8

[0097] Embodiments hereof may include (i) knee portions outside the garment; and/or

(ii) inside the garment. That is, some embodiments may include knee portions only outside the garment, some embodiments may include knee portions only inside the garment, and some embodiments may include knee portions both inside and outside the garment.

[0098] It will be understood by a person of ordinary skill in the art, upon reading this specification, that examples provided herein are meant for demonstration and conceptual purposes, and do not limit the scope of the pants 110, the legs 114, 116 or the expandable knee sections 112 in any way. It is also understood that the pants 110, the legs 114, 116 and the expandable knee sections 112 may be formed and configured using any of the details described in relation to the examples described above, using any combinations of the examples shown above, or using any other methods that may result in the knee sections 112 being adequately configured with the legs 114, 116. It is clear that the scope of this disclosure includes the pants 110, the legs 114, 116 and/or the knee sections 112 being formed or generally constructed and configured together in any manner, whether or not the pants 110, the legs 114, 116 and/or the knee sections 112 include the sections, elements, forms or steps of construction described herein.

[0099] A person of ordinary skill in the art will also recognize that the elements, shapes, pieces and/or forms shown and/or described, e.g., the lower leg sections 114-2, 116-2, the partial lower leg sections 114-2', 116-2', the knee sections 112-1, 112-2, the partial knee sections 112-1', 112-2', the upper leg sections 114-1, 116-1, the partial upper leg sections 114-1', 114-2', the partial length sections 114-4, 116-4, the cutout sections 114-5, 116-5, the cutout regions 124, the combined leg pieces 114A, 114C, 114D, and 114E, the legs 114, 116 and any other elements, sections, pieces or forms, shown and/or described herein with reference to any or all embodiments and/or figures, that may represent the various elements of the embodiments described, are shown for conceptual purposes and are not meant to represent the shapes, sizes, dimensions or forms of the actual elements, sections, pieces or forms. In addition, the shapes, elements, pieces and forms shown are not to scale. The shapes, sizes, forms and dimensions of the actual elements, sections and pieces of the embodiments may be any shapes, sizes, forms and dimensions that may be adequate for the embodiments and may depend on the type of garment that the elements and pieces may ultimately form. For example, the knee sections 112 may be oval shaped, diamond shaped or may comprise other shapes and/or combinations of shapes or forms. This will be described below.

[00100] Also, the lines that may illustrate the positions of the knee sections 112 (or other types of sections) in the figures described herein (e.g., lines B'-B-B' and C'-C-C in FIG. 6B or any other lines in any other figures), may not necessarily be straight lines as depicted, but may be curved lines or lines formed into other shapes that may correspond to the shapes and forms of the actual knee sections 112 that may be configured.

[00101] Although shown in the various drawings as rectangular in shape, it should be appreciated that the knee sections 112-1’ may be other shapes (e.g, oval, semi-oval, circular, diamond, trapezoid, triangular, etc.). Also, while shown in the drawings are symmetric (around at least one axis), the knee sections may be asymmetric around one or more axes or around all axes.

[00102] In addition, while the elements or sections, including the lower leg sections 114-2, 116-2, the partial lower leg sections 114-2', 116-2', the knee sections 112-1, 112-2, the partial knee sections 112-1', 112-2', the upper leg sections 114-1, 116-1, the partial upper leg sections 114-1', 114-2', the partial length sections 114-4, 116-4, the cutout sections 114-5, 116-5, the front partial length sections 114-6, 116-6, the combined leg pieces 114A, 114B, 114C, 114D, 114E, 114F, and 114G, the legs 114, 116 and any other elements, sections, pieces or forms, have each been described as generally being formed from single pieces, any of the elements described may each be formed using more than one piece, and the more than one pieces may be aligned and attached together ( e.g stitched) to generally form each element(s). For example, the lower leg section 114-2 may comprise more than one piece, and the pieces may be joined together in any fashion to generally form the complete lower leg section 114-2. The resulting combined lower leg section 114-2 may then be attached to the knee section 112-1 as described. It is clear that any of the sections, whether formed of single pieces, more than one piece, or any

combination thereof, may then be combined as described above to form the combined leg pieces 114A, 114B, 114C, 114D, 114E, 114F, and 114G It is appreciated that this also applies to the elements, pieces and segments that may be combined to form leg pieces 16A, 116B, 116C,

116D, 116E, 116F, and 116G. The scope of the elements or sections described herein is not limited in any way by the number of pieces that may be used to form any of the elements or sections, nor the way the elements or sections may be configured together.

[00103] In all of the embodiments described herein, it is understood that the examples described are meant for conceptual and demonstration purposes, and that the knee sections 112-1, 112-2, 112-1', and 112-2' (collectively and individually 112) may be formed, positioned and configured anywhere on the legs 114, 116. In addition, the partial knee sections 112-1', 112-2' may extend any amount of width of the legs 114, 116. It may be preferable that the knee sections 112-1, 112-2, 112-1', 112-2' may cover or otherwise be located in close proximity to the front portions of the knees, when the garment is worn. In this way, the knee sections 112 may provide added protection, ruggedness and strength to the legs 114, 116 in these areas. In addition, the knee sections 112-1, 112-2, 112-1', 112-2' may preferably have stretch and recovery properties and may stretch and recover depending on the motions and movements of the legs, when worn. For example, when the legs bend at the knees, the knee sections 112 may expand, and when the legs may return to a generally straight orientation, the knee sections 112 may return to their original sizes and shapes. This will be described in detail in other sections of this specification.

[00104] In addition, while some of the embodiments described herein may generally result in the leg 114 having a side stitch along the line A'-B'-C'-D', and the side line A-B-C-D generally forming a fold line, it may also be desirable for the leg 114 to have a side stitch line along the line A-B-C-D that closes the leg loop (the inner area 122) instead of (or in addition to) a side stitch line along the line A'-B'-C'-D'. In this case, the leg pieces 114A, 114B, 114C,

114E, and 114F, may be oriented such that the line A'-B'-C'-D' may form a fold line along the side of the leg 114 with a side stitch line along the line A-B-C-D. It is also understood that the leg 114 may be formed having a side stitch along the line A'-B'-C'-D' and a side stitch along the line A-B-C-D, or any combination thereof. Note that the number or placement of the stitch lines on the leg 114 does not limit the scope of the embodiments described herein in any way. It is also understood that the leg 116 may also include any number of stitch lines in any position or combinations of positions on the leg 116.

[00105] In addition, any of the elements described herein may be formed using a single-ply of material (a single-ply piece), from a double-ply of material (a double-ply piece), or from any other number of plies or types of materials or pieces.

[00106] The pants 110 may have long legs 114, 116, three-quarter legs, short legs or any other types, shapes or lengths of legs 114, 116. It may be preferable that the lengths of the legs 114, 116 may extend, at least partially, over the knee region, when worn, so that the knee sections 112 may at least partially cover the knees. The knee sections 112 may be configured and incorporated with other types of garments other than pants 112 such as one piece suits, jumpers and other types of garments.

[00107] Note that in any of the embodiments described herein, the elements of the pants 110 ( e.g ., the knee sections 112) may also be attached using attachment methods other than sewing such as fabric welding, adhesives or other attachment methods. In addition, the knee sections 112 may be attached with different and/or other attachment methods in different places or parts. For example, the connections between the knee sections 112 and the lower leg sections 114-2, 116-2 along lines B-B' and F-F’ (FIGS. 1A and IB) may differ from the connections between the knee sections 112 and the upper leg sections 114-1, 116-1 along lines C-C and G-G’. Attachment methods may differ, e.g., in the kind of method (e.g, stitching vs. welding or the like), or in the kind of stitching.

[00108] In general, when pieces are described herein as being joined (e.g, connected or attached), it should be appreciated that they may be joined in any manner acceptable in the art. For example, pieces of material may be joined by being sewn together using an appropriate stitch and/or stitching technique for the material and for their location on a garment. Those of ordinary skill in the art will know and understand suitable techniques to join components.

[00109] The knee sections 112 and other pieces may have border regions (not shown) that can be used for connecting (e.g, stitching) to adjacent pieces. In general, in the drawings, the knee sections 112, knee section pieces, and pants pieces are exemplary in shape and border or stitching regions may not be shown. Thus, when portions or sections or pieces are described herein as having a particular shape (e.g, oval, diamond, square, rectangular, etc.), it should be understood that the portions or segments may include appropriate seam or sew margins to allow connection to adjacent pieces. These seam or sew margins are not shown in the exemplary shapes shown in the drawings.

[00110] The pants 110 may be made with a general fabric, or a self-fabric that may be any general pants fabric, including wool, a wool blend, cotton, a cotton blend, polyester, a polyester blend, denim, poly-cotton, linen, polyester, etc. The self-fabric may also be rigid material, mechanical stretch material, stretch material ( e.g Lycra or Spandex), or other types of materials.

[00111] It is clear that any and all possible shapes or forms, or combinations of shapes or forms, of knee sections 112 are contemplated within this disclosure. The edges of the knee sections 112 may be straight, curved, smooth or any combination thereof, and may include curvatures, patterns or other elements. One or both legs 114, 116 may have knee sections 112, and the knee section 112 on the right leg 114 need not match the knee section 112 on the left leg 116. The knee sections 112 may be configured with the pants 110 using any method, including the methods described in the above examples, combinations of the methods described in the above examples, and/or any other methods or combinations of any other methods.

[00112] With reference now to FIGS. 20A and 20B, the knee sections 112 (for any of the knee sections described above and/or contemplated herein) may be formed from a single-ply of material (a single-ply piece), from a double-ply of material (a double-ply piece), or from any other number of plies or types of materials or pieces. For example, with reference to FIG. 20A, a knee section 112 according to exemplary embodiments hereof, may be formed from a single-ply piece 126.

[00113] In another example, with reference now to FIG. 20B, a knee section 112 according to exemplary embodiments hereof, may be formed from two pieces, an inner piece 128 and an outer piece 130. The inner piece 128 may be positioned on the inside of the knee section 112, when worn, while the outer piece 130 may be positioned on the outside of the knee section 112, when worn. The inner and outer pieces 128, 130 are preferably substantially matching in shape and may be overlaid (and/or underlaid) to form the knee section 112. The knee section 112 may be generally configured with the legs 114, 116 in the area of the knee when attached to pants 110, and worn.

[00114] Note that the knee section 112 of FIGS. 20A and 20B may generally correspond to the knee section 112 of FIGS. 1A and IB. That is, the knee section 112 shown individually in FIGS. 20A and 20B may generally include the shape and form of the knee section 112 attached to the legs 114, 116 in FIG. 1A and IB, and the knee section 112 configured with the leg piece 114A in FIGS. 6A and 6B. For purposes of this description, the process and method by which the knee section 112 may be formed will be described in relation to the knee section 112 depicted in FIGS. 20A and 20B. However, it is understood that the knee sections 112 depicted in FIGS. 20A and 20B are shown for demonstration and representational purposes, and that the knee sections 112 of the other embodiments described herein may also be formed as described in this section. It is also understood that the material properties and benefits that may result due to the forming of the knee section 112 as described will apply to all of the knee sections 112 in all of the embodiments included herein. [00115] Thus, as explained, a knee section may comprise one or more pieces. As explained, a knee section 112 preferably comprises a fabric, and/or a self-fabric ( e.g ., the same self-fabric as used in the pants), with at least some of the knee section 112 having stretch and recovery properties in at least one direction thereof, and preferably in at least two non-opposing directions thereof.

[00116] The knee section piece(s) having stretch and recovery may be formed in any known way. For example, knee section piece(s) may be formed by fusing together a self-fabric with a fusible substrate (e.g., with a one-way, two-way, a four-way or an «-way fusible substrate where an «-way fusible substrate is a fusible substrate that provides stretch and recovery in « directions, and « may equal any number). Thus, each knee section piece having stretch and recovery may comprise a fused fabric composite formed from a fabric (e.g, the self-fabric of the pants or a different fabric) having a fusible material attached thereto (e.g, by fusing the two materials together). A fusible substrate may also be referred to herein as a fusible. The material formed by fusing a self-fabric with a fusible substrate may be referred to as performance material.

[00117] The recovery of the knee sections and/or the pants combined with the knee sections may occur over different lengths of time depending on a variety of conditions and characteristics, including but not limited to, (a) the types and characteristics of the materials used for the pants and the knee sections, (b) the construction of the pants and knee sections, (c) the environment in which the pants and knee sections may be worn, (d) the types and durations of movements the person wearing the pants and knee sections may make, (e) the conditions under which the pants and knee sections may be washed, as well as other characteristics of the pants and the knee sections, and other conditions that the pants and knee sections may experience. For example, the recovery may occur over sixty seconds or less, over five minutes, over one hour, over several hours (e.g, six hours), over 12 hours, over days, weeks or even months. In addition, the recovery may require washing or other conditions (such as heating, cooling, becoming wet, drying and other conditions) to occur. It is clear to a person of ordinary skill in the art, upon reading this specification, that the recovery of the pants and/or knee sections may occur at any time after the stretch has occurred, and that the pants and/ or knee sections may require conditions to trigger and/or facilitate the recovery (e.g, washing). It is also clear that the scopes of the exemplary embodiments described herein are in no way limited by the amount of time required for the recovery to take place or the conditions under which the recovery may be facilitated.

[00118] The piece 126 (FIG. 20A) and/or the inner and outer pieces 128, 130 (FIG. 20B) may each be formed by fusing a fabric or a self-fabric (e.g, the self-fabric of the pants or any other type of fabric) with a fusible substrate. The fusible substrate used may preferably be a two-way fusible substrate, although other fusible substrates ( e.g ., one-way, four-way or «-way fusible substrates where an «-way fusible substrate is a fusible substrate that provides stretch and recovery in « directions, and « may equal any number) may also be used and are contemplated.

[00119] A two-way fusible substrate may be a fusible substrate that provides stretch and recovery in two directions thereof (preferably in non-opposing directions), typically, but not necessarily, perpendicular to each other.

[00120] For the purposes of this discussion, one of the stretch (and recovery) directions may be referred to as a vertical or height direction. Another stretch (and recovery) direction may be in the horizontal or width direction. Preferably the fused material formed by fusing a fabric with a fusible substrate (i.e., the performance material) is formed with the vertical direction of the fusible substrate substantially along the height of the knee section 112, and the horizontal direction of the fusible substrate substantially along the width of the knee section 112.

[00121] As used herein, with reference to the stretch (and/or recovery) properties of a material, a direction may refer to a single direction with respect to a particular point or location or orientation or to substantially opposing directions with respect to that particular point or location or orientation. The term“opposing directions” refers to directions that are at or about 180 degrees opposed to each other. In other words, directions that are substantially opposed to each other. Thus, e.g., with respect to a mid-point on a knee section, a particular fabric having horizontal stretch (and recovery) has stretch (and recovery) to the right and left (i.e., in two opposing directions).

[00122] In some preferred embodiments the fusible substrate is a two-way fusible substrate having greater stretch in the vertical or height direction thereof, preferably about 90% vertical stretch, with the other direction of stretch being about 10%. In other preferred embodiments, the two-way fusible substrate may have somewhat equal stretch and recovery in the vertical and horizontal directions. The two-way fusible substrate may also have other amounts of stretch and recovery in the vertical direction compared to the horizontal direction, and the scope of the embodiments described herein is not limited by the amounts of stretch and recovery that the fusible may have in any direction with respect to any other direction.

[00123] The fabric used to form the piece 126 and/or the inner and outer pieces 128, 130 may be any general fabric, patch fabric or panting fabric, including, for example, wool, a wool blend, cotton, a cotton blend, polyester, a polyester blend, patch fabric, pants fabric, denim, poly cotton, linen, a compacted woven material, and a compacted knit material, etc. The self-fabric may also be rigid material, mechanical stretch material, stretch material (e.g, Lycra or Spandex), or other types of materials. The fabric may, but need not be, the same fabric as that of the pants. The fabric may be a more rugged fabric than that of the pants. The pants may use more than one self-fabric. [00124] The fabric used to form the piece 126 and/or the pieces 128, 130 may be cut in any way, including, e.g., along its length, breadth, or on a bias.

[00125] The fabric used to form the piece 126 and/or the pieces 128, 130 may initially be with or without stretch (e.g, a compacted woven or compacted knit material).

[00126] In some embodiments, the piece(s) of the knee section 112 (i.e., the piece 126 and/or the inner and outer pieces 128, 130) may be formed by first compacting the underlying fabric to give it stretch properties, and then combining the compacted underlying fabric with the fusible substrate (to control and give memory to the stretch imposed by the compaction). As should be appreciated, the underlying fabric has the capacity to extend, and that the extension and recovery is affected by the fusible substrate.

[00127] In the embodiments described with reference to FIGS. 17A, 17B, 18A, 18B, 19A, and 19B, the underlying pants fabric that may be overlaid (and/or underlaid) with the knee section 112 may include stretch properties, and the overlaid (and/or underlaid) knee sections 112 may provide recovery. The underlying pants fabric may be cut on the bias, or may be compacted to give it stretch properties, and then combined with the knee sections 112 to control and give memory to the stretch imposed by the bias and/or the compaction. In this case, it may be preferable for the knee sections 112 to be fused with the compacted leg fabric to form the leg pieces 114E, 114F and/or 114G in order to best provide memory and recovery to the leg piece 114E, 114F and/or 114G in the area of the knee section 112.

[00128] FIG. 21 shows an exemplary material 210 for a knee section 112, according to exemplary embodiments hereof, formed from a fabric and a fusible substrate. The fabric used for this material may be any general fabric, patch fabric or panting fabric, including, for example, wool, a wool blend, cotton, a cotton blend, polyester, a polyester blend, patch fabric, pants fabric, denim, poly cotton, linen, a compacted woven material, and a compacted knit material, etc. The fabric may also be rigid material, mechanical stretch material, stretch material (e.g, Lycra or Spandex), or other types of materials. The fabric used for this material may be cut in any way, including, e.g, along its length, breadth, or on a bias thereof. The fabric used for this material may initially be with or without stretch (e.g, a compacted woven or compacted knit material). The fabric may be compacted with the fusible substrate. The material 210 may be used alone or in combination with other materials.

[00129] FIGS. 22A-22G show exemplary side views of various embodiments with a knee section and leg portion of a garment. FIGS. 23A-23C show aspects of top views pant knee sections according to exemplary embodiments.

[00130] In the example of FIG. 22A, a knee section 112 is positioned on the outside (or overlaid) on the leg portion 114. As used here, the term "outside" (or "outer") refers to the outside of the garment and the term "inside" (or "inner") refers to the inside of the garment. [00131] In the example of FIG. 22B, a knee section 112 is positioned on the inside (or underlaid) on the leg portion 114. As with the example of FIG. 22A, the material used for the knee section 112 and the material used for the leg 114 may, but need not, differ in one or more of: thickness, strength, composition, and yarn per unit area.

[00132] In the example of FIG. 22C, a knee section 112A is positioned on the outside (or overlaid) on the leg portion 114, and a knee section 112B is positioned on the inside (or underlaid) on the leg portion 114. The knee sections 112A and 112B may, but need not be, formed with the same material and may, but need not be, the same size and/or shape. For example, knee section 112A may be the same material and size and shape as knee section 112B. Or, as another example, knee section 112A may be the same material as knee section 112B but differ in size and/or shape. In yet another example, knee section 112A may differ from knee section 112B in material and/or size and/or shape. For example, the outside knee section 112A may be formed with a material comprising the same fabric as that of the leg portion and/or of the garment (so as to match), whereas the inside knee section 112B may be formed from a material that does not use or comprise the same fabric as the leg portion and/or the garment. In general, the two knee sections (outer section 112A and inner section 112B) may, but need not, differ in one or more of: size, shape, area, thickness, strength, composition, and yarn per unit area. FIG. 23A shows an exemplary top view of embodiments according to FIG. 22C. As shown in FIG. 23 A, the outer piece 112A is oval shaped and the inner piece 112B (shown in dashed lines) is rectangular. The leg portion 114 between the two pieces 112A, 112B, is not shown in the drawing of FIG. 23A.

[00133] FIG. 22D shows a knee section 112 attached to a leg portion 114 (e.g., the embodiments of FIGS. 5. 6A-6B, 8A-8B, 12A-12B, 13A, 14A-14B, 15A and 16A-16B) As shown in FIG. 22D, the knee section 112 is essentially inline with the leg portion 114.

[00134] FIG. 22E shows an embodiment, as in the example of FIG. 22D, with an knee section 112A positioned on the outside (or overlaid) on the leg portion 114 and positioned over an inline knee section 112. The knee section 112A may be, but need not be, greater in size and/or area than the inline knee section 114 and may, but need not, completely cover the inline knee section 112. The knee sections 112A and 112 may, but need not be, formed with the same material and may, but need not be, the same size and/or shape. In general, the two knee sections (outer section 112A and inline section 112) may, but need not, differ in one or more of: size, shape, area, thickness, strength, composition, and yarn per unit area.

[00135] As shown in FIG. 23B, corresponding to the examples of FIG. 22E, the outer piece 112A is oval shaped and the inline piece 112 (shown in dot-dashed lines) is rectangular with rounded corners. [00136] FIG. 22F shows an embodiment, as in the example of FIG. 22D, with a knee section 112B positioned on the inside (or underlaid) on the leg portion 114 and positioned over the inline knee section 112. The knee section 112B may be, but need not be, greater in size and/or area than the inline knee section 114 and may, but need not, completely cover the inline knee section 112. The knee sections 112B and 112 may, but need not be, formed with the same material and may, but need not be, the same size and/or shape. In general, the two knee sections (inner section 112B and inline section 112) may, but need not, differ in one or more of: size, shape, area, thickness, strength, composition, and yarn per unit area.

[00137] FIG. 22G shows an embodiment, as in the example of FIG. 22D, with (i) a knee section 112A positioned on the outside (or overlaid) on the leg portion 114 and positioned over the inline knee section 112; and (ii) a knee section 112B positioned on the inside (or underlaid) on the leg portion 114 and positioned over the inline knee section 112. The knee sections 112A and 112 may, but need not be, formed with the same material and may, but need not be, the same size and/or shape. The knee section 112B may be, but need not be, greater in size and/or area than the inline knee section 112 and may, but need not, completely cover the inline knee section 112. The knee sections 112B and 112 may, but need not be, formed with the same material and may, but need not be, the same size and/or shape. In general, the three knee sections (outer section 112A, inline section 112, and inner section 112B) may, but need not, differ in one or more of: size, shape, area, thickness, strength, composition, and yarn per unit area.

[00138] As shown in FIG. 23C, corresponding to the examples of FIG. 22G, the outer piece 112A is oval shaped, the inner piece 112B (shown in dashed lines) is rectangular, and the inline piece 112 (shown in dot-dashed lines) is rectangular with rounded corners. The leg portion 114 between the two pieces 112A, 112B, is not shown in the drawing of FIG. 23A.

[00139] The examples in FIGS. 23A-23C are merely exemplary, and are not intended to limit embodiments in any way (including by shape or relative size or alignment).

[00140] In all of the example embodiments, the material used for the knee section(s) 112 and the material used for the leg 114 may, but need not, differ in one or more of: thickness, strength, composition, and yarn per unit area.

[00141] In some preferred embodiments, the material used for knee section is stronger than the material used for the leg portion. This additional strength may be achieved, at least in part, by the material used for the knee section having more yarn per unit area (e.g., about 5% to about 16% or even 20% more) than the material used for the leg portion.

[00142] A particular knee section may, but need not, have the same thickness over its entirety. For example, a knee section (e.g., any of knee sections 112A, 112, and 112B in the examples of FIGS. 22A-22G) may be of uniform thickness, or a knee section may have different thicknesses at different parts thereof. For example, a knee section may be thicker at its center than at its edges.

[00143] Similarly, a particular knee section may, but need not, have the same strength (e.g., yarn per unit area) over its entirety. For example, a knee section (e.g., any of knee sections 112A, 112, and 112B in the examples of FIGS. 22A-22G) may be of uniform strength, or a knee section may have different strengths (e.g., different amounts of yam per unit area) at different parts thereof. For example, a knee section may be stronger at its center than at its edges.

[00144] As shown in FIG. 24, the knee section 112 (e.g., piece 126 and/or the inner and outer pieces 128, 130 and/or other types of knee sections 112) may preferably be formed from fabric having stretch and recovery in one, two or other numbers of directions. In one exemplary embodiment, the knee section 112 may preferably have stretch and recovery in a substantially vertical direction (e.g, generally in the direction of arrowed line B-B' in FIG. 24, from up to down and down to up). In another exemplary embodiment, the knee section 112 may preferably have stretch and recovery in a substantially horizontal direction (e.g, generally in the direction of arrowed lines A-A' in FIG. 24, from right to left and left to right). In preferred exemplary embodiments, the knee section 112 has primary stretch (i.e., greater stretch) and corresponding recovery in the direction along the leg from the waist to the ankle). This direction (from waist to foot) may be referred to the vertical direction, and may correspond to in the direction of arrowed line B-B’ in the drawing in FIG. 24.

[00145] In addition (or instead), in some exemplary embodiments the knee sections 112 may include stretch and recovery in other directions that may be at different angles (offset angles) with respect to the vertical or horizontal directions (e.g, in the directions of arrowed lines C-C' and/or D-D' in FIG. 24). Note that while the directions of stretch and recovery represented by the angled arrow lines C-C' and D-D' may be shown in the drawing in FIG. 24 as generally offset at approximately 45 degrees with respect to lines A-A' and B-B', the directions of stretch and recovery represented by the lines C-C and D-D' may be offset at any angles or any combinations of angles with respect to arrowed lines A-A' and B-B'.

[00146] Furthermore, it is understood that the knee section 112 may include stretch and recovery properties in multiple directions simultaneously. For example, the knee section 112 may simultaneously include stretch and recovery in the vertical direction (e.g, in the direction of arrowed lines B-B') as well as in the directions of any offset angles represented by the angled arrow lines C-C and D-D'. Recall that while the arrowed lines C-C and D-D' are depicted as being generally 45 degrees with respect to the horizontal arrowed lines B-B', the angled arrowed lines C-C and D-D' may represent directions of stretch and recovery at any offset angles with respect to the arrowed lines B-BV The knee section 112 may include stretch and recovery properties simultaneously in multiple directions, and each direction may be at any offset angle with respect to the offset angles represented by the arrowed lines C-C and D-D'. This example is meant for demonstration purposes and it is understood by a person of ordinary skill in the art that the knee sections 112 may include stretch and recovery properties simultaneously in any combination of angles and/or directions.

[00147] While the knee section 112 may have substantial stretch and recovery in the vertical and horizontal directions, the knee section 112 may have at least some stretch and recovery in any other direction with respect to the knee section 112. Furthermore, while preferable embodiments have primary stretch and recovery (i.e., the most stretch and recovery) in substantially the vertical direction (i.e., along line B-B' in FIG. 24), and/or in substantially the horizontal direction (i.e., along the line A-A' in FIG. 24), other embodiments may have primary stretch and recovery in any other directions or angles or in any combination of other directions or angles.

[00148] Those of ordinary skill in the art will appreciate and understand, upon reading this description that the direction of a knee section’s primary stretch and recovery may also depend on the type of activities the wearer will perform when wearing the garment / pants 110. For example, a work pants worn as part of a uniform by a construction worker may need primary stretch and recovery in the vertical direction, whereas pants worn by military personnel may need primary stretch and recovery at a non-zero angle from the vertical ( e.g ., along lines D-D' and C-C' in FIG. 24).

[00149] While the arrowed lines in FIG. 24 show four generally opposing directions

(A-A', B-B', C-C, D-D'), those of ordinary skill in the art will appreciate and understand, upon reading this description, that any directions or number of directions are possible. Furthermore, the angles between the arrowed lines in FIG. 24 are not to scale or representative of actual angles.

[00150] In some exemplary embodiments hereof, it may be preferable for the knee section 112 to have stretch and recovery of at least 1.5 to 2.0 inches in the vertical direction (e.g., along the height of the knee section). However, lesser or greater amounts of stretch and recovery may also be used and are contemplated herein.

[00151] While FIG. 24 may illustrate the stretch and recovery properties of the knee section 112 configured with the right leg 114, it is understood by a person of ordinary skill in the art that a knee section 112 configured with the left leg 116 may include at least the same aspects as described in relation to the knee section 112 configured with the right leg 114. In addition, the knee section 112 configured with the right leg 114 may or may not be configured with the right leg 114 the same way as the knee section 112 may be configured with the left leg 116. For example, the knee section 112 configured with the right leg 114 may have a different shape, a different number of plies, may be integrated into the leg 114 differently, may have a different relative position on the leg 114, may be oriented differently relative to the leg 114, or may have any other aspect that may be the same or different compared to how the knee section 112 may be configured with the left leg 116.

[00152] It is also clear that a knee section 112 configured with the right leg 114, and a knee section configured with the left leg 116, may stretch and recover independent of each other depending on the movements of the body, when worn ( e.g ., the movements of the wearer’s right leg within the garment’s right leg 114 and/or the movements of the wearer’s left leg within the garment’s left leg 116). The knee section 112 configured with the right leg 114 may

simultaneously stretch and recover in directions and angles that may be different or the same compared to the directions and angles that the knee section 112 configured with the left leg 116 may stretch and recover.

[00153] It is understood that the angles between the arrowed lines in FIG. 24 are not to scale or representative of actual angles, and those of ordinary skill in the art will appreciate and understand, upon reading this description, that any directions or number of directions are possible for stretch and recovery in the knee section 112 in FIG. 24.

[00154] As described above, the knee section 112 may be configured with other leg sections (e.g., lower leg section 114-2, upper leg section 114-1, or any other sections) and the resulting leg piece (e.g, 114A or any other leg piece) may be formed into a loop with an inner area 122 to generally form the legs 114, 116. This is shown in FIG. 25. It is clear that while FIG. 25 may depict a cross-sectional view that may resemble the cross-sectional view shown in FIG. 7, the cross-sectional view depicted in FIG. 25 is for demonstration purposes and may represent any of the cross-sections of any of the knee section 112 and/or leg 114, 116 embodiments, or combinations of embodiments described herein.

[00155] As shown, the knee section loop 112 may have expansion and contraction properties (stretch and recovery) generally outward and inward radially along its perimeter or circumference. As represented by the arrowed lines in FIG. 25, the knee section loop 112 may expand in any or all radial directions simultaneously and subsequently contract in any or all radial directions simultaneously. It is understood that the arrowed lines M-M’, N-N’, 0-0’ and P-P’ are meant for conceptual purposes and may therefore represent directions and angles of simultaneous radial expansion and subsequent contraction at any angles and locations or combinations of any angles and locations about the general perimeter or along the circumference of the knee section loop 112. Note that the radial expansions and subsequent contractions may be in addition to, or a result of, the stretch and recovery described above with reference to FIG. 24

[00156] In one example, with the knee section 112 formed as described above, configured with a leg 114, 116 and pants 110, and worn, the knee section 112 may expand substantially along the direction and angle represented by the arrowed line N, as well as along offset directions and/or offset angles represented by arrowed lines O and P’, when a person wearing the pants 110 may bend their leg at the knee. Upon bending the knee back straight, the knee section may contract along similar axis. If the person may then bend their knee and rotate their leg outward from hip, the knee section loop 112 may expand substantially along the arrowed line N as well as along directions and/or offset angles represented by arrowed lines O and M. It will be clear to a person of ordinary skill in the art that the examples above are meant for demonstration purposes and that the knee section loop 112 may expand and contract in any directions and/or angles, individually or simultaneously, and that the directions and/or angles of the individual or simultaneous expansions and subsequent contractions do not limit the exemplary embodiments described herein in any way.

[00157] Another representation of these movements may be shown in FIGS. 26A and 26B. For illustrative purposes, the knee section 112 of FIG. 26A may resemble the knee section 112 of FIG. 1A, and the knee section of FIG. 26B may resemble the knee section 112 of FIG. 2A. As shown, the knee section 112 may generally stretch in the direction of the arrowed lines S and T when the pants are worn and the knee is bent. These directions may generally include vectoral components in the Z directions and the Y directions. It can be seen that if the leg ( e.g ., the ankle) were then to be rotated outward in the X direction, that the knee section 112 may also stretch with vectoral components in the X direction.

[00158] The knee section 112 described herein provides numerous advantages over prior approaches. As is known in the art, when pants is worn, movements made by the lower body of the user (e.g., bending the legs at the knees) may cause the legs 114, 116 of the pants 110 (including the knee section 112) to become taut, causing the legs 114, 116 to bind on the wearer. The knee section 112 described herein provides the ability of the pants 110 to expand to better accommodate leg movements, thus minimizing the tautness and binding of the garment. Having stretched or expanded, when the motion is over, the knee section 112 is then able to return substantially to its original dimensions (due to the recovery properties imparted by the fusible). This may provide a much higher level of comfort to persons who may wear the pants 110 configured with the knee sections 112 while performing duties that may involve moving and bending their legs.

[00159] In any of the embodiments described herein, the knee section 112 may be configured with the legs 114, 116 of the pants 110 such that the fabric layer may be facing outward (away from the leg when worn) or inward (facing the leg when worn). In addition, the knee section 112 may be configured with the legs 114, 116 of the pants 110 such that the fusible substrate may be facing outward (away from the body when worn) or inward (facing the body when worn). The self-fabric and/or the fusible substrate may be printed with a pattern or may be unprinted. When the fusible may be facing towards the legs when worn, the fusible may wick moisture ( e.g perspiration) away from the body to give the material additional performance.

This may be especially effective when the knee section 112 is formed of a single-ply material.

[00160] As noted, a knee section 112 according to exemplary embodiments hereof may be formed using a material and/or fabric that is stronger or thicker than the underlying garment material (i.e., than the material and/or fabric used to make the garment). The added strength or thickness may be achieved by using more yam per unit area in the knee section(s) 112 than in surrounding parts of the leg or the rest of the leg.

[00161] Thus, in the examples above, the material and/or fabric used for the knee sections 112-1, 112-2 may use more yarn per unit area than the material and/or fabric used for the sections 114-1, 114-2, 116-1, and 116-2 (FIGS. 1A, IB, 5, 6A, 6B). Similarly, the material and/or fabric used for the knee sections 112-1’, 112-2’ in FIGS. 2A, 3A, 4A-4B, 8A, 9A, 9B,

11 A, 12A, 12B, 13A, 14A-14B, 15A, and 16A-16B, may use more yarn per unit area than the material used for the corresponding legs 114, 116 (or leg portions 114-1’, 114-2’, 116-1’,

116-2’). And similarly, the material and/or fabric used for he knee section 112-1 in the examples of FIGS. 17A-17B, 18A-18B, may use more yarn per unit area than the material and/or fabric used for the section 114; and, the material and/or fabric used for he knee section 112-1’ in the examples of FIGS. 19A-19B, may use more yarn per unit area than the material and/or fabric used for the section 114-6.

[00162] In general, those of ordinary skill in the art will appreciate and understand, upon reading this description, that the amount (if any) of extra yarn per unit area used in the knee section may depend on factors such as the intended use of the garment and the type and/or strength of the underlying garment or leg fabric.

Conclusion

[00163] Where a process is described herein, those of ordinary skill in the art will appreciate that the process may operate without any user intervention. In another embodiment, the process includes some human intervention (e.g., a step is performed by or with the assistance of a human).

[00164] As used herein, including in the claims, the phrase“at least some” means“one or more,” and includes the case of only one. Thus, e.g, the phrase“at least some ABCs” means “one or more ABCs”, and includes the case of only one ABC.

[00165] As used herein, including in the claims, term“at least one” should be understood as meaning“one or more”, and therefore includes both embodiments that include one or multiple components. Furthermore, dependent claims that refer to independent claims that describe features with“at least one” have the same meaning, both when the feature is referred to as“the” and“the at least one”.

[00166] As used in this description, the term“portion” means some or all. So, for example,“A portion of X” may include some of“X” or all of“X”. In the context of a conversation, the term“portion” means some or all of the conversation.

[00167] As used herein, including in the claims, the phrase“using” means“using at least,” and is not exclusive. Thus, e.g., the phrase“using X” means“using at least X.” Unless specifically stated by use of the word“only”, the phrase“using X” does not mean“using only X”

[00168] As used herein, including in the claims, the phrase“based on” means“based in part on” or“based, at least in part, on,” and is not exclusive. Thus, e.g, the phrase“based on factor X” means“based in part on factor X” or“based, at least in part, on factor X.” Unless specifically stated by use of the word“only”, the phrase“based on X” does not mean“based only on X.”

[00169] In general, as used herein, including in the claims, unless the word“only” is specifically used in a phrase, it should not be read into that phrase.

[00170] As used herein, including in the claims, the phrase“distinct” means“at least partially distinct.” Unless specifically stated, distinct does not mean fully distinct. Thus, e.g, the phrase,“X is distinct from Y” means that“X is at least partially distinct from Y,” and does not mean that“X is fully distinct from Y” Thus, as used herein, including in the claims, the phrase“X is distinct from Y” means that X differs from Y in at least some way.

[00171] It should be appreciated that the words“first” and“second” in the description and claims are used to distinguish or identify, and not to show a serial or numerical limitation.

Similarly, the use of letter or numerical labels (such as“(a)”,“(b)”, "(i)", "(ii), and the like) are used to help distinguish and / or identify, and not to show any serial or numerical limitation or ordering.

[00172] As used herein, including in the claims, the terms“multiple” and“plurality” mean “two or more,” and include the case of“two.” Thus, e.g, the phrase“multiple ABCs,” means “two or more ABCs,” and includes“two ABCs.” Similarly, e.g, the phrase“multiple PQRs,” means“two or more PQRs,” and includes“two PQRs.”

[00173] As used herein, including in the claims, singular forms of terms are to be construed as also including the plural form and vice versa, unless the context indicates otherwise. Thus, it should be noted that as used herein, the singular forms“a,”“an,” and“the” include plural references unless the context clearly dictates otherwise. [00174] Throughout the description and claims, the terms“comprise”,“including”, “having”, and“contain” and their variations should be understood as meaning“including but not limited to”, and are not intended to exclude other components unless specifically so stated.

[00175] It will be appreciated that variations to the embodiments of the invention can be made while still falling within the scope of the invention. Alternative features serving the same, equivalent or similar purpose can replace features disclosed in the specification, unless stated otherwise. Thus, unless stated otherwise, each feature disclosed represents one example of a generic series of equivalent or similar features.

[00176] The present invention also covers the exact terms, features, values and ranges, etc. in case these terms, features, values and ranges etc. are used in conjunction with terms such as about, around, generally, substantially, essentially, at least etc. (i.e., "about 3" shall also cover exactly 3 or "substantially constant" shall also cover exactly constant).

[00177] Use of exemplary language, such as“for instance”,“such as”,“for example” (“e.g”) and the like, is merely intended to better illustrate the invention and does not indicate a limitation on the scope of the invention unless specifically so claimed.

[00178] Thus are provided an expandable and flexible pants knee section and pants with the same.

[00179] While the invention has been described in connection with what is presently considered to be the most practical and preferred embodiments, it is to be understood that the invention is not to be limited to the disclosed embodiment, but on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
