DETAILED DESCRIPTION

[0027] Referring generally to the figures, one or more support platforms that support utility modules within a modular system are shown. The support platforms include one or more back supports configure to attach to surfaces of a structure, such as walls. The support platforms provide coupling mechanisms, such as female couplers, to couple to utility modules with corresponding male couplers within a modular system. In use, the support platform is coupled to a surface, such as a wall, and one or more utility modules are coupled to the support platform via engagement between the male and female couplers.

[0028] In various embodiments, the support platform includes one or more stamped face plates. Applicant has observed that using a stamping process to manufacture the face plates provides a very high degree of shape and geometric consistency between individual stamped plates facilitating the stacking or tiling multiple face plates next to each other.

[0029] The term 'utility module' is used hereinafter in its broad meaning and is meant to denote a variety of articles such as, storage containers, travel luggage, tool boxes, organizers, compacted work benches, cable storage, tools (e.g. hand tools, power generators and power sources), communication modules, carrying platforms, locomotion platforms, beverage containers, etc., of any shape and size, and wherein any utility module can be detachably attached to the modular system.

[0030] Referring to FIGS. 1-4, various aspects of a mechanism, shown as support platform 110, for supporting and storing utility modules are shown. Support platform 110 includes face plate 130, face plate 131, lower plates 140, and back plates or supports 120. Back supports 120 are coupled to a back of each of the face plate 130, face plate 131, and lower plates 140. Support platform 110 includes a plurality of female couplers 160 configured to couple to male couplers of utility modules. In various embodiments, the face plate 130, 131, 140 is formed from a metal material. In a specific embodiment, the face plate 130, 131, 140 is formed from steel. In various embodiments, the face plate 130, 131, 140 is formed from a contiguous piece of metal material, and the plurality of female couplers 160 are stamped into the metal.

[0031] One or more face plates (e.g., face plate 131) include one or more latch recesses 137 configured to receive a latch extending from the utility module. When a latch from a utility module is engaged with a latch recess 137, the male couplers of the utility module are biased or prevented from disengaging from female couplers 160.

[0032] Referring to FIG. 2, support platform 110 is expandable along both a horizontal or longitudinal axis 112 and a vertical or transverse axis 114, thereby enabling users to add an unlimited number of female couplers 160 to the support platform 110. As will be explained, one or more protrusions extend from a bottom of a face plate interfaces with one or more recesses defined by a top of a face plate to facilitate alignment between the face plates when both are secured to a wall. Similarly, one or more protrusions extend from a side of a face plate and the protrusion(s) interface with one or more recesses defined by an opposing side of another face plate to facilitate alignment between the face plates when both are secured to a wall.

[0033] Face plate 130 includes a plurality of apertures 136 arranged in a grid between top 132 and bottom 134 of face plate 130. Face plate 130 includes two rows of female couplers 160, so two back supports 120 are coupled to a rear of face plate 130. As will be explained, apertures 136 of face plate 130 and back supports 120 collectively define the plurality of female couplers 160.

[0034] Face plate 131 is functionally and structurally similar to face plate 130 except as described herein. In particular, face plate 131 only includes a single row of female couplers 160 and face plate 131 is approximately half as tall as face plate 130.

[0035] Lower face plate 140 is functionally and structurally similar to face plate 131 except as described herein. In particular, lower face plate 140 includes a top 142 with a recess 150 configured to receive and/or interface with protrusion 138 of upper face plate 130. In various embodiments, the protrusion 138 has a generally polygonal shape. In a specific embodiment, protrusion 138 has a trapezoidal shape. Lower face plate 140 includes apertures 146 arranged in a line, the apertures 146 being configured to partially define the female couplers 160. Lower face plate 140 also includes a protrusion 148 protruding downward, the protrusion 148 configured to interface with the recess of another lower face plate 140 placed below. In various embodiments, the protrusion 148 has a generally polygonal shape. In a specific embodiment, protrusion 148 has a trapezoidal shape

[0036] In various embodiments, the female couplers 160 and the male couplers described and shown herein are compatible with the coupling mechanism(s) described in International Patent International Patent Publication No. WO 2017/191628, which is hereby incorporated by reference in its entirety.

[0037] Support platform 110 can include any number of face plates 130, face plates 131, lower plates 140, and back supports 120. Referring to FIG. 3, in a specific embodiment support platform 110 includes face plate 130 and a first lower face plate 140. A top 142 of first lower face plate 140 interfaces with a bottom 134 of face plate 130. Support platform 110 also includes face plate 131 interfacing with a right side of face plate 130. A second lower face plate 140 interfaces with a bottom of face plate 131, and a third lower face plate 140 interfaces with a bottom of second lower face plate 140 (e.g., a top 142 of third lower face plate 140 interfaces with a bottom 144 of second lower face plate 140).

[0038] Referring to FIG. 4, support platform 110 includes a plurality of female couplers 160. In particular, face plate 130 defines a first plurality 192 of female couplers 160 and a second plurality 193 of female couplers 160. Face plate 140 in the lower left comer of FIG. 4 defines a third plurality 194 of female couplers 160. Face plate 131 defines a fourth plurality 195 of female couplers 160. Face plate 140 in the center right of FIG. 4 defines a fifth plurality 196 of female couplers 160. Face plate 140 in the lower right corner of FIG. 4 defines a sixth plurality 197 of female couplers 160. In various embodiments, the female couplers 160 are arranged in a plurality of columns 116 and rows 118.

[0039] Face plate 130 extends between a first outer edge 208 and a second outer edge 210. First outer edge 208 and second outer edge 210 extend between top 132 and bottom 134 of face plate 130. In other words, first outer edge 208 and second outer edge 210 extend along vertical axis 114. Similarly, face plate 140 extends between a first outer edge 204 and a second outer edge 206. First outer edge 204 and second outer edge 206 extend between top 142 and bottom 144 of face plate 140. Face plate 131 extends between a first outer edge 212 and a second outer edge 214.

[0040] As shown in FIG. 4, face plate 130 is coupled to face plate 131 such that the first plurality 192 of female couples 160 are aligned with the fourth plurality 195 of female couplers 160. When face plate 130 and face plate 131 are arranged in such an orientation, second outer edge 210 of face plate 130 engages with and/or interfaces against first outer edge 212 of face plate 131. Similarly, face plate 140 in the lower right corner of FIG. 4 and the sixth plurality 197 of female couplers 160 are aligned with face plate 140 in the lower left corner of FIG. 4 and the third plurality 194 of female couplers 160. Second outer edge 206 of face plate 140 in the lower left corner engages with and/or interfaces against first outer edge 204 of face plate 140 in the lower right corner. In such an arrangement, a horizontal axis 112 of the first face plate 140 is collinear with a second horizontal axis 112 of the second face plate 140.

[0041] Referring to FIGS. 5-6, various aspects of support platform 110 are shown. As can be seen, female couplers 160 are defined by back support(s) 120 and the apertures of one of face plates 130, 131 or lower face plate 140.

[0042] Referring to FIG. 6, various aspects of female coupler 160 are shown. Female coupler 160 includes a recessed surface 164 defined by back support 120. Back wall 166, opposing front wall 172, first sidewall 168, and opposing second sidewall 170 extend around female coupler 160. Female coupler 160 includes a pocket 174 collectively defined by recessed surface 164, back wall 166, front wall 172, first sidewall 168, and second sidewall 170.

[0043] First rib 176 extends from back wall 166 and first sidewall 168 above pocket 174 and/or recessed surface 164. In particular, first rib 176 extends in direction 182 from first sidewall 168 and first rib 176 extends in direction 180 from back wall 166. Second rib 178 extends from back wall 166 and second sidewall 170 above pocket 174 and/or recessed surface 164. In particular, second rib 178 extends in direction 184 from second sidewall 170 and second rib 178 extends in direction 180 from back wall 166.

[0044] First lateral protrusion 186 extends downward from first sidewall 168 towards recessed surface 164. Second lateral protrusion 188 extends downward from second sidewall 170 towards recessed surface 164. Back protrusion 190 extends downward from back wall 166 towards recessed surface 164. First lateral protrusion 186, second lateral protrusion 188, and/or back protrusion 190 facilitate single cleat locking mechanisms (e.g., rotating male couplers) coupling to one of the female couplers 160.

[0045] To couple female coupler 160 to a male coupler, the male coupler moves in direction 162 with respect to the female coupler 160. First lateral protrusion 186, second lateral protrusion 188, and/or back protrusion 190 interface with the male coupler to facilitate the male coupler engaging with and/or disengaging with the female coupler 160.

[0046] Back support 120 includes a plurality of coupling mechanism, shown as apertures 122, configured to couple back support 120 to a surface, such as a wall. In various embodiments, apertures 122 are arranged in a first line 124 at an upper portion of back support 120 and a second line 126 at a lower portion of back support 120. In such an embodiment, the first line 124 is spaced from second line 126 by a distance. In a specific embodiment, the first line 124 and the second line 126 of apertures 122 extend along horizontal axis 112. In use, users couple the back support 120 to a wall (e.g., via a stud in the wall) with a fastener or anchor, such as a bolt or screw, through apertures 122 in first line 124 and/or second line 126.

[0047] Referring to FIGS. 7-11, various aspects of support platform 110 are shown. As will be described in greater detail below, in a specific embodiment, face plate 130, face plate 131, and/or face plate 140 are manufactured from 2.5 mm thick steel and are made with two stamping operations. First, a hit will cut the entire outside edge of the part in a "blanking" operation. As will be generally understood, blanking differs from punching or piercing types of stamping in that the cut piece is the required portion of the metal piece instead of the cut or removed metal being a scrap piece. Second, a stamping hit will cut out the cleat pockets, locker pockets, and possibly any holes needed for welding. The cleat pocket tabs (e.g., protrusions 186, 188, 190) will be bent in a separate operation.

[0048] In various embodiments, back support 120 is another stamped piece of steel that is bent and then welded onto the back of the face plates 130, 131, 140. Back support 120 has rows of slots (e.g., apertures 122) for mounting to walls. In various embodiments back support 120 is a lower grade of steel or thinner compared to the face plates 130, 131, 140. The punched out areas between bent tabs (e.g., protrusions 186, 188, 190) are for clearance of PACKOUT™ accessory cleats into the cleat pockets of the face plate. In various embodiments, back support 120 is welded to the face plates 130, 131, 140 in the bent tab areas. The height of each of back supports 120 away from the wall and its tolerance aligns the face plates 130, 131, and 140 from one rail (e g., combination of a face plate 130, 131, 140 and a back support 120) to the next allowing the system to tile. In various embodiments where the plurality of female couplers 160 are arranged in rows, a number of rows of the female couplers 160 will be the same as a number of back supports 120 coupled to the face plate 130, 131, 140.

[0049] Back support 120 includes a first longitudinal sidewall 189 extending along horizontal axis 112 and a second longitudinal sidewall 191 extending in a generally parallel orientation (i.e., parallel plus or minus 10 degrees) to the first longitudinal sidewall 189. Recessed surface 164 extends between the first longitudinal sidewall 189 and the second longitudinal sidewall 191. A plurality of apertures 122 extend through recessed surface 164. Apertures 122 are configured to couple the back support 120 to a surface such that the support platform 110 is supported from the surface.

[0050] The first longitudinal sidewall 189 and second longitudinal sidewall 191 each extend between a first end 200 and a second end 202 of back support 120. Back support 120 further includes a plurality of tabs 216 extending inward (i.e., toward the opposing longitudinal sidewall) from first longitudinal sidewall 189 and second longitudinal sidewall 191. The plurality of tabs 216 include openings 218 positioned between adjacent tabs 216, with the openings 218 positioned along horizontal axis 112. Openings 218 ensure tabs 216 do not extend into the space of pocket 174 collectively defined by recessed surface 164, back wall 166, front wall 172, first sidewall 168, and second sidewall 170.

[0051] When a face plate 130 includes a plurality of female couplers 160 arranged in a first row and a second row, the first row and the second row each extend along the horizontal axis 112 of face plate 130. A first back support 120 is positioned behind the first row of the plurality of female couplers 160 and the second back support 130 is positioned behind the second row of the plurality of female couplers 160. In such an embodiment, a second longitudinal sidewall 191 of the first back support 120 is generally parallel (i.e., parallel plus or minus 10 degrees) a first longitudinal sidewall 189 of the second back support 120. [0052] Back support 120 is undersized vertically and horizontally compared to the face plate 130, 131, 140. In various embodiments, back supports 120 do not touch each other when vertically or horizontally tiling rails. In such an embodiment, at least a portion of the face plate 130, 131, 140 extends beyond the corresponding back support 120 in a vertical direction (i.e., along vertical axis 114) and in a horizontal direction (i.e., along horizontal axis 112). In other words, face plates 130, 131, 140 have a major or longitudinal dimension that is greater than a major or longitudinal dimension of back support 120. In a specific embodiment, the first outer edge 208 of face plate 130 extends beyond first end 200 of back support 120 second outer edge 210 of face plate 130 extends beyond second end 202 of back support 120. Similarly, face plates 130, 131, 140 have a minor or transverse dimension that is greater than a minor or transverse dimension of back support 120.

[0053] In particular, a first gap, shown as G1 is positioned between the first longitudinal sidewall 189 and the second longitudinal sidewall 191 of an adjacent back support 120. In other words, G1 provides a space between the adjacent back supports 120 such that adjacent back supports 120 do not touch each other along vertical axis 114. Similarly, a second gap, shown as G2 is positioned between the first end 200 and second end 202 of adjacent back supports 120. As such G2 provides a space between back supports 120 that are adjacent to each other along horizontal axis 112. In various embodiments this arrangement helps with the tolerance stack and permits excluding bends and material thicknesses from the stacks.

[0054] Referring to FIG. 12, the tolerance from the first cleat to the second cleat below is +/- 1.5 mm, and the tolerance from the first cleat to the third cleat below is +/- 2.0 mm.

[0055] FIG. 13 provides a flow diagram of a method 300 for forming a support platform 110 according to the present disclosure. In a first step 301 of the method 300, a piece and/or sheet of metal is positioned on a die or mold. In a specific embodiment, the metal sheet is a 2.5 mm thick steel sheet. In particular, the metal sheet is positioned on the die such that the outside edges of the metal sheet are aligned with the die for stamping.

[0056] In a second step 302 of method 300, a first punch is used to apply a force to the metal sheet, the shearing or cutting force creates a cut along an outside edge of the metal sheet in a blanking operation to form a workpiece or face plate 130, 131, 140. In a specific embodiment, the first punch is used to cut along the entire outside edge of the metal sheet. The shape of the die determines the shape of the workpiece.

[0057] In a third step 303 of method 300, a second punch is used to apply a force to the workpiece cutting one or more apertures 136, 146 out of the workpiece 130, 131, 140. In a specific embodiment, the second punch applies a force to cut a plurality of apertures 136, 146 that at least partially define female couplers 160. In various specific embodiments, the second punch applies the force to cut a plurality of apertures 136, 146 that at least partially define female couplers 160 in a row (i.e., along horizontal axis 112) and/or a column (i.e., along vertical axis 114). In a specific embodiment, each aperture 136, 146 includes at least one protrusion 186, 188, 190 extending from the face plate 130, 131, 140 into the space of the aperture.

[0058] In various specific embodiments, the second punch cuts a plurality of apertures 136, 146 that at least partially define female couplers 160 and a plurality of latch recesses 137. In such an embodiment, the plurality of latch recesses 137 are positioned in a row (i.e., along horizontal axis 112) along the face plate 130, 131, 140. The latch recesses 137 are configured to receive a latch extending from the utility model. In various embodiments, the second punch applies a force to cut the plurality of apertures 136, 146 that at least partially define female couplers 160, the plurality of latch recesses 137 and a plurality of holes. As will be discussed below, such holes can be used to couple the face plate 130, 131, 140 to the back support 120.

[0059] In the fourth step 304 of method 300, a die is used to bend one or more of the protrusions 186, 188, 190 extending from the face plate 130, 131, 140 into the open space of the aperture 136, 146 that at least partially defines the female coupler 160. In particular, the one or more protrusions 186, 188, 190 are bent downward relative to an upper surface of the face plate

130, 131, 140 to an angle. In a specific embodiment, the protrusions 186, 188, 190 are bent to an angle between 30 and 90 degrees from the upper, outward facing surface of the face plate 130,

131, 140, specifically between 40 and 80 degrees, and more specifically between 50 and 70 degrees. In such an embodiment, the protrusions 186, 188, 190 are bent to an angle of about 60 degrees (i.e., 60 degrees plus or minus 5 degrees).

[0060] In a fifth step 305 of method 300, the back support 120 is coupled to the face plate 130, 131, 140. In particular, an upper surface of back support 120 is coupled to a rear surface of face plate 130, 131, 140 such that the recessed surface 164 of back support 120 together with back wall 166, front wall 172, first sidewall 168, and second sidewall 170 of face plate 130, 131, 140 defines the pocket 174. In a specific embodiment, face plate 130, 131, 140 is welded to back support 120. In such an embodiment, holes will have been punched in the face plate 130, 131, 140 in positions as needed to allow for the welding.

[0061] Before coupling back support 120 to face plate 130, 131, 140, back support 120 is aligned below the plurality of apertures 136, 146 that are arranged in a row. Aligning back support 120 ensures that back support 120 does not touch or engage with adjacent back supports coupled to the same face plate 130, 131, 140 or to an adjacent face plate 130, 131, 140.

[0062] When back support 120 is coupled to face plate 130, 131, 140 to form support platform 110, the support platform 110 includes a plurality of female couplers 160 defined by back support 120 and the face plate 130, 131, 140. Each of the female couplers 160 includes a recessed surface 164 defined by the back support 120 and an edge of each of the plurality of apertures 136, 146 of the face plate includes a first rib 176 and a second rib 178. The first rib 176 and second rib 178 extend above the recessed surface 164.

[0063] In various embodiments, back support 120 is a stamped piece of metal. In a specific embodiment, back support is formed from steel. In various specific embodiments, back support 120 is formed from a lower grade steel than the steel used to form face plate 130, 131, 140. In a specific embodiment, the metal used to form the back support has a thickness less than a thickness of the metal sheet used to form the face plate 130, 131, 140. In other words, in such an embodiment, the metal sheet used to form back support 120 is less than 2.5 mm in thickness.

[0064] In a specific embodiment, a third punch is used to apply a force to the metal sheet cutting one or more apertures 136, 146 out of the back support workpiece. In a specific embodiment, the third punch applies a force to cut a plurality of slots or apertures 122 into the metal sheet. In various embodiments, the third punch applies a force to cut apertures 122 arranged in a first line 124 and a second line 126 into the back support workpiece. Once the back support workpiece is bent into the desired shape, the face plate 130, 131, 140 can be coupled to the fully formed back support 120.
