STRAP SYSTEM FOR ARTICLE OF FOOTWEAR

CROSS REFERENCE TO RELATED APPLICATION

[0001] This PCT International application claims priority to U.S. Patent Application Serial Number 16/881,551, filed May 22, 2020, the disclosure of which is hereby incorporated by reference in its entirety.

FIELD

[0002] The present disclosure relates generally to articles of footwear having a strap system for moving the footwear between a tightened state and a loosened state.

BACKGROUND

[0003] This section provides background information related to the present disclosure and is not necessarily prior art.

[0004] Articles of footwear conventionally include an upper and a sole structure. The upper may be formed from any suitable material(s) to receive, secure, and support a foot on the sole structure. A bottom portion of the upper, proximate to a bottom surface of the foot, attaches to the sole structure. Sole structures generally include a layered arrangement extending between an outsole providing abrasion-resistance and traction with a ground surface and a midsole disposed between the outsole and the upper for providing cushioning for the foot.

[0005] The upper may cooperate with laces, straps, or other fastening systems to adjust the fit of the upper around the foot. For instance, laces may be tightened to close the upper around the foot and tied once a desired fit of the upper around the foot is attained. Care is required to ensure that the upper is not too loose or too tight around the foot each time the laces are tied.

[0006] While known fastening systems adequately secure an upper of an article of footwear to a foot of a wearer, such systems require use of two hands to properly tension and tie laces of the fastening system. As such, conventional systems are not easily used by persons having use of only one arm or hand. DRAWINGS

[0007] The drawings described herein are for illustrative purposes only of selected configurations and are not intended to limit the scope of the present disclosure.

[0018] Corresponding reference numerals indicate corresponding parts throughout the drawings.

DETAILED DESCRIPTION

[0019] Example configurations will now be described more fully with reference to the accompanying drawings. Example configurations are provided so that this disclosure will be thorough, and will fully convey the scope of the disclosure to those of ordinary skill in the art. Specific details are set forth such as examples of specific components, devices, and methods, to provide a thorough understanding of configurations of the present disclosure. It will be apparent to those of ordinary skill in the art that specific details need not be employed, that example configurations may be embodied in many different forms, and that the specific details and the example configurations should not be construed to limit the scope of the disclosure. [0020] The terminology used herein is for the purpose of describing particular exemplary configurations only and is not intended to be limiting. As used herein, the singular articles “a,” “an,” and “the” may be intended to include the plural forms as well, unless the context clearly indicates otherwise. The terms “comprises,” “comprising,” “including,” and “having,” are inclusive and therefore specify the presence of features, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, steps, operations, elements, components, and/or groups thereof. The method steps, processes, and operations described herein are not to be construed as necessarily requiring their performance in the particular order discussed or illustrated, unless specifically identified as an order of performance. Additional or alternative steps may be employed.

[0021] When an element or layer is referred to as being “on,” “engaged to,” “connected to,” “attached to,” or “coupled to” another element or layer, it may be directly on, engaged, connected, attached, or coupled to the other element or layer, or intervening elements or layers may be present. In contrast, when an element is referred to as being “directly on,” “directly engaged to,” “directly connected to,” “directly attached to,” or “directly coupled to” another element or layer, there may be no intervening elements or layers present. Other words used to describe the relationship between elements should be interpreted in a like fashion (e.g., “between” versus “directly between,” “adjacent” versus “directly adjacent,” etc.). As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items.

[0022] The terms first, second, third, etc. may be used herein to describe various elements, components, regions, layers and/or sections. These elements, components, regions, layers and/or sections should not be limited by these terms. These terms may be only used to distinguish one element, component, region, layer or section from another region, layer or section. Terms such as “first,” “second,” and other numerical terms do not imply a sequence or order unless clearly indicated by the context. Thus, a first element, component, region, layer or section discussed below could be termed a second element, component, region, layer or section without departing from the teachings of the example configurations.

Optionally, the upper may include a lateral side and a medial side opposite the lateral side, the lateral side defining a lateral side of the foot-receiving opening, the medial side defining a medial side of the foot-receiving opening, the panel rotatably coupled to the lateral side or the medial side of the upper. [0033] The details of one or more implementations of the disclosure are set forth in the accompanying drawings and the description below. Other aspects, features, and advantages will be apparent from the description and drawings, and from the claims.

[0034] Referring to FIGS. 1A-4A, an example of an article of footwear 10 including a strap system 300 providing for tensioning relative to a wearer’s foot is disclosed. In some implementations, the article of footwear 10 includes an upper 100 and a sole structure 200 attached to the upper 100. The strap system 300 may include a strap 302 and one or more routing elements 304 (FIG. 4) to manage the tension of the upper 100. As will be explained in more detail below, in some implementations, the upper 100 and the sole structure 200 cooperate to provide passages and guides for routing portions of the strap 302 through the article of footwear 10. The upper 100 and the strap system 300 cooperate to move the article of footwear 10 between a loosened state ( e.g ., FIGS. 1 A and 2A) and a tightened state (e.g, FIGS. IB and 2B). Particularly, the strap 302 is movable in a tightening direction DT (FIGS. 1 A and IB) to move the article of footwear 10 into the tightened state.

[0035] The article of footwear 10, and components thereof, may be described as including an anterior end 12 associated with a forward-most point of the footwear 10, and a posterior end 14 corresponding to a rearward-most point of the footwear 10. As shown in the bottom view of FIG. 3, a longitudinal axis Aio of the footwear 10 extends along a length of the footwear 10 from the anterior end 12 to the posterior end 14, and generally divides the footwear 10 into a lateral side 16 and a medial side 18. Accordingly, the lateral side 16 and the medial side 18 respectively correspond with opposite sides of the footwear 10 and extend from the anterior end 12 to the posterior end 14.

[0036] The article of footwear 10 may be divided into one or more regions along the longitudinal axis Aio. The regions may include a forefoot region 20, a mid-foot region 22, and a heel region 24. The forefoot region 20 may correspond with toes and joints connecting metatarsal bones with phalanx bones of a foot. The mid-foot region 22 may correspond with an arch area of the foot, and the heel region 24 may correspond with rear regions of the foot, including a calcaneus bone. [0037] The upper 100 forms an enclosure having a plurality of components that cooperate to define an interior void 102 and an ankle opening 104, which cooperate to receive and secure a foot for support on the sole structure 200. For example, the upper 100 includes a pair of quarter panels 106 in the mid-foot region 22 on opposite sides of the interior void 102. A throat 108 extends across the top of the upper 100 and defines an instep region extending between the quarter panels 106 from the ankle opening 104 to the forefoot region 20. In the illustrated example, the throat 108 is enclosed with a panel 110 extending between the opposing quarter panels 106 in the instep region to cover the interior void 102. The panel 110 covering the throat 108 may be coupled to one of the quarter panels 106 and/or the forefoot region 20. For example, as illustrated in FIGS. IB and 2B, in some implementations the panel 110 is hingedly coupled to the quarter panel 106 disposed on the medial side 18 of the footwear 10 for movement between an open state ( e.g ., FIGS. 1A and 2A) and a closed state (e.g., FIGS. IB and 2B), where a portion of the panel 110 may overlap a portion of the quarter panel(s) 106 and/or the anterior end 12 of the footwear 10. In this regard, the panel 110 may include an inner surface 111 that engages an outer surface 114 of the upper 100 in the closed state.

[0038] The upper 100 of the article of footwear 10 may be further described as including heel side panels 110 extending from respective quarter panels 106 through the heel region 24 along the lateral and medial sides 16, 18 of the ankle opening 104. A heel counter 112 wraps around the posterior end 14 of the footwear 10 and connects the heel side panels 110. Uppermost edges of the throat 108, the heel side panels 110, and the heel counter 112 cooperate to form a collar 115, which defines the ankle opening 104 of the interior void 102.

[0039] The upper 100 may be formed from one or more materials that are stitched or adhesively bonded together to define the interior void 102. Suitable materials of the upper 100 may include, but are not limited to, textiles, foam, leather, and synthetic leather. The example upper 100 may be formed from a combination of one or more substantially inelastic or non-stretchable materials and one or more substantially elastic or stretchable materials disposed in different regions of the upper 100 to facilitate movement of the article of footwear 10 between the open state (e.g, FIGS. IB and 2B) and the closed state (e.g, FIGS. 1A and 2A). The one or more elastic materials may include any combination of one or more elastic fabrics such as, without limitation, spandex, elastane, rubber or neoprene. The one or more inelastic materials may include any combination of one or more of thermoplastic polyurethanes, nylon, leather, vinyl, or another material/fabric that does not impart properties of elasticity.

[0040] With reference to FIGS. 3-5, the sole structure 200 is attached to the upper 100 and includes a midsole 202 configured to provide cushioning characteristics to the sole structure 200, and an outsole 204 configured to provide a ground-engaging surface 26 of the article of footwear 10. In this regard, as illustrated in FIGS. 4 and 5, the midsole 202 may include a lower surface 206 that engages an upper surface 208 of the outsole 204 in the assembled configuration. As previously described, the sole structure 200 may further receive a portion of the strap system 300 in the assembled configuration. In particular, as illustrated in FIG. 5, the lower surface 206 of the midsole 202 may include one or more channels 209 extending therethrough from the lateral side 16 to the medial side 18, while the upper surface 208 of the outsole 204 may include one or more protrusions 210 extending from the lateral side 16 to the medial side 18. As will be explained in more detail below, the channels 209 may receive the protrusions 210 and route portions of the strap system 300 (e.g., the strap 302 and/or the routing element(s) 304) through the article of footwear 10 in the assembled configuration. In some examples, a portion of the strap 302 may be encapsulated between the midsole 202 and the outsole 204 within the routing element(s) 304 and the channels 209.

[0041] As introduced above, the strap system 300 may be attached to the upper 100 and/or the sole structure 200 for moving the upper 100 between the open state (FIGS. IB and 2B) and the closed state (FIGS. 1 A and 2A). In this regard, the strap 302 may include a proximal end 308 and a distal end 310 opposite the proximal end 308. The proximal end 308 may be coupled to one or both of the upper 100 or the sole structure 200 and may include a first fastener 312. For example, the proximal end 308 may be fixed to the lateral quarter panel 106, proximate the anterior end 12 of the footwear 10, by stitching, adhesive, ultrasonic welding, or any other suitable technique. The first fastener 312 may include a loop, clip, hook-and-loop fastener, or any other suitable fastening system. In this regard, the distal end 310 may include a second fastener 314 that can be selectively coupled to the first fastener 312 in the closed state. For example, the second fastener 314 may include a hook-and-loop fastener configured to be selectively attached to the hook-and-loop fastener of the first fastener 312 in the closed state.

[0042] The strap 302 may be translatably routed through one or both of the upper 100 or the sole structure 200 in the assembled configuration. In this regard, one or more of the quarter panels 106 or the panel 110 may include one or more apertures 316 through which the strap 302 is translatably routed in the assembled configuration. In the illustrated example, the lateral quarter panel 106 includes a first aperture 316-1 proximate the throat 108, the medial quarter panel 106 includes second and third apertures 316-2, 316-3 proximate the throat 108, and the panel 110 includes a fourth aperture 316-4 proximate a lateral edge of the panel 110. As will be explained in more detail below, in the assembled configuration, the strap 302 may be routed through one or more of the apertures 316 such that the strap 302 can translate therethrough.

[0043] With reference to FIGS. 4-5, the routing element(s) 304 may include a first routing element 304-1 and a second routing element 304-2 and may be formed from a rigid or semi-rigid material (e.g., plastic, metal, carbon fiber, etc.). The first routing element 304-1 may include a base portion 318-1 and a pair of side portions 320-1 extending from opposing sides of the base portion 318-1. The second routing element 304-2 may likewise include a base portion 318-2 and a pair of side portions 320-2 extending from opposing sides of the base portion 318-2. In some implementations, the side portions 320-1 of the first routing element 304-1 define a substantially L-shaped construct, such that the first routing element 304-1 defines a substantially C-shaped construct. In the assembled configuration, the side portions 320-2 of the second routing element 304-2 may be disposed within and/or attached to the side portions 320-1 of the first routing element 304-1, such that the base portions 318-1, 318-2 and the side portions 320-1, 320-2 define a passage 319 extending therethrough. One or both of the first or second routing elements 304-1, 304-2 may be disposed within a first channel 209-1 of the channels 209, and one or both of the first or second routing elements 304-1, 304-2 may be disposed within a second channel 209-2 of the channels 209. For example, the routing elements 304-1, 304-2 may be disposed within the channels 209-1, 209-2 and extend from the lateral side 16 to the medial side 18 of the footwear. In some implementations, the base portion 318-1 and the side portions 320-1 engage the midsole 202, while the base portion 318-2 engages the outsole 204.

[0044] In the assembled configuration, the strap 302 may extend (i) from the proximal end 308 coupled to the lateral quarter panel 106 proximate the anterior end 12 of the footwear 10, (ii) through the upper 100 and/or the sole structure 200 (e.g., between the midsole 202 and the outsole 204), (iii) through the second channel 209-2 (e.g., through the routing elements 304-1, 304-2), (iv) through the upper 100 and/or the sole structure 200 (e.g., between the midsole 202 and the outsole 204), (v) through the second aperture 316-2 in the medial quarter panel 106, (vi) across the throat 108 (e.g., traversing (e.g., over, under, through, etc.) the panel 110), (vii) through the fourth aperture 316-4 in the panel 110, (viii) through the first aperture 316-1 in the lateral quarter panel 106, (ix) through the upper 100 and/or the sole structure 200 (e.g., between the midsole 202 and the outsole 204), (x) through the first channel 209-1 (e.g., through the routing elements 304-1, 304- 2), (xi) through the upper 100 and/or the sole structure 200 (e.g., between the midsole 202 and the outsole 204), (xii) through the third aperture 316-3 in the medial quarter panel 106, (xiii) across the throat 108 (e.g., traversing (e.g., over, under, through, etc.) the panel 110), including across (e.g., over or under) the portion of the strap 302 traversing the panel at (vi) such that the strap forms an X-shaped intersection proximate the throat 108, and (xiv) to the distal end 310 selectively coupled to the proximal end 308 proximate the anterior end 12 of the footwear 10. In this way, the straps 302 may completely surround the upper 100 and a portion of the sole structure 200 twice in the mid-foot region 22 of the article of footwear 10.

[0045] With particular reference to FIGS. 6 and 7, another strap system 300a for use with an article of footwear (e.g., article of footwear 10) is shown. In view of the substantial similarity in structure and function of the components associated with the strap system 300a relative to the strap system 300, like reference numerals are used hereinafter and in the drawings to identify like components while like reference numerals containing letter extensions are used to identify those components that have been modified.

[0046] The strap system 300a may include the strap 302 and one or more routing elements 304a to manage the tension of the upper 100. For example, the routing elements 304a may include a primary routing element 304a-l and a pair of secondary routing elements 304a-2. The primary routing element 304a-l may include a first attachment feature 322 disposed at a proximal end 324 of the primary routing element 304a-l, and a second attachment feature 326 disposed at a distal end 328 of the primary routing element 304a-l . The first and second attachment features 322, 326 may each include a pair of recesses 330, 332 formed in opposed upper and lower sides 334, 336 of the primary routing element 304a-l. In some implementations, the first and second attachment features 322, 326 each include a pair of ribs 338 extending from a first lateral side 340 of the primary routing element 304a-l to a second lateral side 342 of the primary routing element 304a- 1. In this regard, the first lateral side 340 may be opposite the second lateral side 342, and the upper side 334 may be opposite the lower side 336 such that the ribs 338 are disposed between the upper and lower sides 334, 336 and extend across one or both of the first or second recesses 330, 332. The primary routing element 304a-l may further include a longitudinal passage 344 extending therethrough from, and through, the proximal end 324 to, and through, the distal end 328. In this regard, the passage 344 may be defined by and between the upper and lower sides 334, 336, the first and second lateral sides 340, 342, and the pair of ribs 338. [0047] The secondary routing elements 304a-2 may include an end portion 346 and a pair of legs 348 extending therefrom. The end portion 346 may include a front side 350, a rear side 352 opposite the front side 350, and an aperture 351 extending through the front and rear sides 350, 352. The legs 348 may extend from the rear side 352 on opposite sides of the aperture 351 and may each include a tooth 354 extending therefrom. In this regard, each tooth 354 may extend from one leg 348 of the pair of legs 348 toward the other leg 348 of the pair of legs 348.

[0048] In an assembled configuration (FIG. 7), the secondary routing elements 304a-2 may be coupled to the proximal and distal ends 324, 328 of the primary routing element 304a-l. For example, the legs 348 may be disposed within the recesses 330, 332 such that (i) each rib 338 is disposed, and secured, between the tooth 354 and the end portion 346, and (ii) the aperture 351 of the secondary routing elements 304a-2 is aligned with the passage 344 of the primary routing element 304a-l.

[0049] The routing elements 304a-l, 304a-2 may be coupled to the sole structure 200 such that the strap 302 can be routed therethrough in the manner previously described relative to the strap system 300. In this regard, the routing elements 304a-l, 304a-2 may be disposed within the channels 209-1, 209-2. Alternatively, the routing elements 304a-l, 304a-2 may be disposed at other locations within the sole structure 200, such as (i) between the midsole 202 and an insole 212, (ii) between the midsole 202 and the outsole 204, or (iii) encapsulated within the midsole 202, the outsole 204, or the insole 212, such that the strap 302 can be translatably routed through the passage 344 and the apertures 351.

[0050] Referring to FIGS. 1A-2B, the articles of footwear 10, 10a can be moved from the open state to the closed state after being placed on a user’s foot by applying a force (e.g., pulling) on the distal end 310 of the strap 302. Pulling on the distal end 310 may cause the strap 302 to translate within and through the routing elements 304, 304a-l, 304a-2 and the apertures 316-1, 316-2, 316- 3, 316-4 in a first direction such that the upper 100 tightens around the user’s foot. To secure the upper in the tightened state, the user can secure the distal end 310 (e.g., the second fastener 314) to the proximal end 308 (e.g., the first fastener 312).

[0051] When the user desires to remove the article of footwear 10, 10a from the foot, the strap system 300, 300a can be moved to the open state to allow the upper 100 to be relaxed around the foot by removing the distal end 310 (e.g., the second fastener 314) from the proximal end 308 (e.g., the first fastener 312) and allowing the strap 302 to translate within and through the routing elements 304, 304a-l, 304a-2 and the apertures 316-1, 316-2, 316-3, 316-4 in a second direction such that the upper 100 loosens around the user’s foot.
