BACKGROUND
Shelves are often used for displaying and/or storing items. For example, a retail outlet, such as a grocery store, typically includes multiple rows of shelves separated by aisles. The rows of shelves typically include shelves having differing configurations suitable for the different types of merchandise being displayed and/or stored.
Many existing shelving systems can be customized to some extent for the display and/or storage of particular items. For example, the number of shelves used and/or the vertical spacing between shelves can often be varied. And the size of the shelves used can be selected in advance based on the space available for the shelf. Existing shelving systems, however, may be insufficiently reconfigurable to avoid having to be replaced with new shelves of a different configuration as part of a reconfiguration of a retail outlet or remodeling of a residence.
Accordingly, there is believed to be a need for shelving systems and related items that can be reconfigured to a greater extent than existing shelving systems.
BRIEF SUMMARY

DETAILED DESCRIPTION
In the following description, various embodiments of the present invention will be described. For purposes of explanation, specific configurations and details are set forth in order to provide a thorough understanding of the embodiments. However, it will also be apparent to one skilled in the art that the present invention may be practiced without the specific details. Furthermore, well-known features may be omitted or simplified in order not to obscure the embodiment being described.
Referring now to the drawings, in which like reference numerals represent like parts throughout the several views, FIG. 1 shows a variable-planform shelving system 10, in accordance with many embodiments. The shelving system 10 is shown in a compact collapsed configuration. The shelving system 10 includes a variable-planform base 12, variable planform shelves 14, four support posts 16, a kick plate assembly 18, and price display assemblies 20. Although two variable planform shelves 14 are shown, the variable-planform shelving system 10 can include any suitable number of variable planform shelves 14 (e.g., 1 or more).
The variable-planform base 12 and each of the variable planform shelves 14 include a support surface assembly 22 that provides a support surface for items supported by the shelving system 10. In the embodiment shown, the support surface assemblies 22 are fabricated from a plurality of vertically-oriented panels that are intermittently bonded together such that a support surface assembly 22 can be expanded in a lengthwise direction 24 (perpendicular to the orientation of the vertically-oriented panels) without any substantial contraction perpendicular to the lengthwise direction 24. In addition to being expandable in the lengthwise direction 24, the support surface assembly 22 is flexible to conform to a variety of curved planforms in which the shelving system 10 can be configured.
FIG. 2 shows the shelving system 10 in the compact collapsed configuration with the support surface assemblies 22 removed to better show details of a base support platform 26 portion of the variable-planform base 12 and a variable support platform 28 portion of the shelves 14. The base support platform 26 supports a support surface assembly 22. Likewise, each of the variable support platforms 28 support a support surface assembly 22. The base support platform 26 and the variable support platforms 28 are supported by the four support posts 16.
The base support platform 26 and the variable support platforms 28 are reconfigurable into any of a continuous range of different planforms including expanded planforms, a variety of curved planforms, and combinations thereof. Each variable support platform 28 includes a first frame 30, a second frame 32, and a third frame 34. The third frame 34 has an elliptical outer perimeter. Each of the first and second frames 30, 32 have an outer perimeter shape of a half ellipse. A first portion of the third frame 34 is slidably received within a horizontally-oriented slot in the first frame 30 and a second portion of the third frame 34 is slidably received within a horizontally-oriented slot in the second frame 32. The planform of the variable support platform 28 is selectively varied by repositioning and/or reorienting the third frame 34 relative to the first frame 30 and/or relative to the second frame 32.
In a similar fashion, the planform of the base support platform 26 can be selectively varied. The planform of the base support platform 26 and the planform of each of the variable support platforms 28 can be varied in the same way so that each of the support posts 16 remains vertical. For example, FIG. 3 shows the shelving system 10 in a partially expanded configuration with the support surface assemblies 22 removed to better show the partially expanded states of the base support platform 26 and the variable support platforms 28.
The base support platform 26 includes an upper portion 36 and a lower portion 38. The upper portion 36 includes a first upper frame 40, a second upper frame 42, and a third upper frame 44 that are configured similar to the first, second, and third frames 30, 32, 34 of the variable support platforms 28. The third upper frame 44 has an elliptical outer perimeter. Each of the first and second upper frames 40, 42 has an outer perimeter in the shape of a half ellipse. A first portion of the third upper frame 44 is slidably received within a horizontally-oriented slot in the first upper frame 40 and a second portion of the third upper frame 44 is slidably received within a horizontally-oriented slot in the second upper frame 42. Likewise, the lower portion 38 includes a first lower frame 46, a second lower frame 48, and a third lower frame 50 that are configured similar to the first, second, and third frames 30, 32, 34 of the variable support platforms 28. The third lower frame 50 has an elliptical outer perimeter. Each of the first and second lower frames 46, 48 has an outer perimeter in the shape of a half ellipse. A first portion of the third lower frame 50 is slidably received within a horizontally-oriented slot in the first lower frame 46 and a second portion of the third upper frame 50 is slidably received within a horizontally-oriented slot in the second lower frame 48. The planform of the base support platform 26 is selectively varied by repositioning and/or reorienting the third upper and third lower frames 44, 50 relative to the first upper and first lower frames 40, 46 and/or relative to the second upper and second lower frames 42, 48.
Additional details of the shelving system 10 will now be described with reference to FIG. 4, which shows the shelving system 10 in a fully expanded in-line configuration. As shown, the third frame 34 of the variable support platforms 28 has a elongated aperture 52 that extends from one end of the third frame 34 to the other. The elongated aperture 52 receives a first coupling pin 54 that is coupled with the first frame 30 and extends across the first frame slot, thereby extending through the elongated aperture 52. The elongated aperture 52 further receives a second coupling pin 56 that is coupled with the second frame 32 and extends across the second frame slot, thereby extending through the elongated aperture 52. In the fully expanded in-line configuration, the coupling pins 54, 56 are disposed at opposing ends of the elongated aperture 52, thereby retaining the ends of the third frame 34 within the first and second frame slots. Additionally, the coupling pins 54, 56 can be configured to clamp the first and second frames 30, 32 onto the third frame, thereby preventing inadvertent reconfiguration of the variable support platform 28 and enhancing the transfer of bending moments from the third frame 34 to the first and second frames 30, 32. In many embodiments, suitable threaded fasteners are used as the coupling pins 54, 56.
The upper and lower portions 36, 38 of the base support platform 26 are connected by intermediate members (e.g., a column members). Adjacent to the support posts 16, the first upper and first lower frames 40, 46 are connected by two column members 58. Likewise, adjacent to the other support posts 16, the second upper and second lower frames 42, 48 are connected by two column members 60. The third upper and third lower frames 44, 50 are connected by two column members 62 disposed midway along opposing sides of the third upper and third lower frames 44, 50. A column member 64 connects the first upper and first lower frames 40, 46. The column member 64 can also be configured to clamp the first upper and first lower frames 40, 46 onto the third upper and third lower frames 44, 50, respectively, thereby preventing inadvertent reconfiguration of the base support platform 26 and enhancing the transfer of bending moments from the third upper and third lower frames 44, 50 to the first upper and first lower frames 40, 46. For example, a suitable threaded fastener can be used in conjunction with the column member 64 to provide the clamping force. A column member 66 connects the second upper and second lower frames 42, 48. The column member 66 can also be configured to clamp the second upper and second lower frames 42, 48 onto the third upper and third lower frames 44, 50, respectively, thereby preventing inadvertent reconfiguration of the base support platform 26 and enhancing the transfer of bending moments from the third upper and third lower frames 44, 50 to the second upper and second lower frames 42, 48. For example, a suitable threaded fastener can be used in conjunction with the column member 66 to provide the clamping force. A height adjustable support 68 is disposed directly below each of the column members 62 and helps to stabilize the base support platform 26.
FIG. 5 shows the shelving system 10 in the fully expanded in-line configuration without the support surface assemblies 22 removed. In many embodiments, the support surface assemblies 22 are coupled with the underlying support platforms at suitable locations (e.g., along the ends and at intermediate points along the lengthwise edge) such that the planform of the support surface assemblies is constrained to conform to the planform of the underlying support platforms.
FIG. 6 shows the shelving system 10 in a fully expanded curved configuration with the support surface assemblies 22 not shown to better illustrate the relative orientations between the frames of the base support platform 26 and the variable support platforms 28. FIG. 7 shows the same configuration with the support surface assemblies not removed. As shown, the planform of the variable support surface assemblies 22 varies to conform to the planform of the underlying support platforms. FIG. 8 and FIG. 9 show the shelving system 10 in another fully expanded curved configuration. And FIG. 10 and FIG. 11 show the shelving system 10 in yet another fully expanded curved configuration.
FIG. 12 shows the shelving system 10 (with the support surface assemblies 22 not shown) in another fully expanded curved configuration with a removable support column 70 added to provide additional support to the variable support platforms 28. In the configuration of FIG. 12, the support posts 16 are substantially aligned. In many embodiments, the connection between the support posts 16 and the variable support platforms 28 is configured to react mainly shear load. Accordingly, the removable support column 70 provides an additional support that is offset from the aligned support posts 16. With shear only connections between the variable support platforms 28 and the aligned support posts 16, the support column 70 provides required additional support to the variable support platforms 28. FIG. 13 shows the same configuration with the support surface assemblies 22 not removed and the support column 70 not shown. As can be seen, with shear load only type connections between the variable support platforms 28 and the aligned support posts 16, the support column 70 provides necessary offset support to the variable support platforms 28 to balance eccentricity between the items supported by the shelves and the aligned support posts 16.
FIG. 14A shows a plan view of a variable support platform 28 in the compact collapsed configuration. The first frame 30 includes a straight base member 72, a half-elliptical perimeter member 74, and cross members 76. The perimeter member 74 and the cross members 76 are slotted so as to accommodate the illustrated end portion of the third frame 34. Likewise the second frame 32 includes a straight base member 78, a half-elliptical perimeter member 80, and cross members 82. The perimeter member 80 and the cross members 82 are slotted so as to accommodate the illustrated end portion of the third frame 34. At the corners of the first and second frames 30, 32, semi-circular recesses 84 are configured to accommodate the support posts 16. Adjacent to the semi-circular recesses 84, hanger apertures 86 are located to accommodate a portion of a supporting hanger bracket that is removably attached to one of the support posts 16. The hanger apertures 86 extend circumferentially around the recesses 84 for a limited extent so as to accommodate a suitable range of angular orientations of the support post 16 and the attached hanger bracket. The first, second, and third frames 30, 32, 34 include attachment apertures 88 that can be used to attach the price display assembly 20 shown in FIG. 1. And the third frame 34 includes attachment features 90 for the support column 70 shown in FIG. 12.
The central aperture 52 of the third frame 34 receives the coupling pins 54, 56, which are coupled with the first and second frames 30, 32 and extend across the slots in the first and second frames 30, 32, thereby extending through the central aperture 52. The central aperture 52 is configured to allow constrained movement of the third frame 34 relative to the first frame 30 and/or relative to the second frame 32, including changes in angular orientation of the third frame 34 relative to the first frame 30 and/or relative to the second frame 32.
The variable support platform 28 includes additional features that allows for its use as either the upper portion 36 of the base support platform 26 or the lower portion 38 of the base support platform 26. For example, the first frame 30 includes circular apertures 92 for the attachment of the column members 58 as shown in FIG. 4. The second frame 32 includes circular apertures 94 for the attachment of the column members 60. And the third frame 34 includes circular apertures 96 for the attachment of the column members 62.
FIG. 14B through FIG. 14E show details of how a variable support platform 28 is supported from one of the support posts 16. FIG. 14B shows bracket-receiving slots 98, 100 in the support posts 16. In many embodiments such as the one shown, the support posts 16 have a plurality of bracket-receiving slots at regular intervals, thereby providing for numerous combinations of numbers of shelves and/or spacing of shelves. FIG. 14C shows a hanger bracket 102 partially inserted in a first opening 100 of the support post 16. FIG. 14D shows the hanger bracket 102 attached to the support post 16. And FIG. 14E shows a close-up side view of the hanger bracket 102 attached to one of the support posts 16 and supporting a corner of a variable support platform 28. Additional details of a suitable approach for supporting the variable planform shelves 14 are described in U.S. Pat. No. 5,415,302, entitled “MODULAR SHELVING SYSTEM WITH A QUICK-CHANGE SHELF FEATURE,” the entire disclosure of which is hereby incorporated by reference herein.
Any suitable fabrication method and material can be used to make the variable support platform 28. For example, in many embodiments, the first, second, and third frames 30, 32, 34 of the variable support platform 28 are made from components cut (e.g., using a water-jet) from a suitable constant thickness sheet of material. FIG. 15 shows a plan view of components that can be used to make the first, second, and third frames 30, 32, 34 of the variable support platform 28. The first frame 30 can be made from a first upper component 104, a first lower component 106, and first spacer components 108. The first spacer components 108 are disposed between the first upper and first lower components 104, 106 so that the outer perimeter and common features of these components are aligned. The first spacer components 108 serve to separate the first upper and first lower components 104, 106 so as to form the slot that receives part of the third frame 34. In the same way, the second frame 32 can be made from a second upper component 110, a second lower component 112, and second spacer components 114. The second spacer components 114 are disposed between the second upper and second lower components 110, 112 so that the outer perimeter and common features of these components are aligned. The second spacer components 114 serve to separate the second upper and second lower components 110, 112 so as to form the slot that receives part of the third frame 34. The third frame 34 can be made from a third frame component 116 and third spacer components 118. The third spacer components 118 are disposed on top of the third frame component so that the outer perimeter and common features of these components are aligned. The third spacer components 118 provide an upper surface to the third frame 34 that is in plane with the upper surfaces of the first and second frames 30, 32. Any suitable method for joining the components can be used (e.g., bonding, welding, brazing, fastening).
Additional details of the variable support base 26 will now be described with references to FIG. 16. The variable support base 26 includes two cylindrical sleeves 120 at each corner. The sleeves 120 interface with the support posts 16 and rigidly tie the support posts to the variable support base 16, thereby stiffening the shelving system 10 against lateral deflection of the shelves 14 relative to the variable support base 26.
Details of the kick plate assembly 18 and the price display assembly 20 will now be described with reference to FIG. 17 through FIG. 28. Both the kick plate assembly 18 and the price display assembly 20 are configured to expand and conform to all of the possible planform configurations of the base support platform 26.

End frames of the base support platform 182 includes flanges 192 that are bolted to the base beam 190, thereby rigidly connecting the base support platform to the support columns 184, 186. FIG. 32 shows a support surface assembly 22 coupled to and supported by one of the base support platforms 182. FIG. 33 shows a close-up view of an end of one of the variable support platforms 188, which includes an integral end support beam 194. Each of the end support beams 194 is attached to and cantilevered from one of the support columns 184, 186.
FIG. 34 through FIG. 36 show a wall-mounted variable-planform shelving system 200, in accordance with many embodiments. The shelving system 200 includes variable support platforms 202 that are configured similar to the variable support platforms 188. Each of the variable support platforms is attachable to a wall 204 via two or more support beams 206. For example, FIG. 34 shows a single variable support platform 202 in a compact collapsed configuration attached to the wall 204 via two support beams 206 disposed at opposing ends of the variable support platform 202. FIG. 35 shows a single variable support platform 202 in a fully-expanded configuration attached to the wall 204 via three support beams 206. FIG. 36 shows a single variable support platform 202 in a fully-expanded configuration that wraps around a corner of the wall 204. And FIG. 37 shows three variable support platforms 202 that wrap around two corners of the wall 204. As can be appreciated, the wall-mounted variable-planform shelving system 200 can be used and/or adapted for use with numerous wall configurations having different lengths, external corners, and/or internal corners.
FIG. 38A and FIG. 38B show a variable-length clothes rack 210 having a variable-planform base 212, in accordance with many embodiments. The variable planform base 212 is configured similar to the variable planform base 12 described herein. Supported from the variable planform base 212 is an extendable top beam 214 from which clothes can be hung. The extendable top beam 214 can be reconfigured to various lengths corresponding to the various possible planforms of the variable planform base 212. The extendable top beam 214 is supported by two support columns 216, which are rigidly connected to opposing ends of the variable planform base 212. The extendable top beam 214 includes two flexible strap members 218, segments of which are held in tension between the tops of the support columns 216. For example, ends of the strap members 218 can be attached to the top of one of the support columns 216 and an intermediate location of each of the strap members 218 can be clamped to the top of the opposing support column 216 to maintain the tension in the strap members 218 between the tops of the support columns 216. As shown, the variable planform base 212 includes a support surface assembly 22 that can be used to support additional items (e.g., shoes, boots, etc.).
FIGS. 39A, 39B, and 39C show plan views of the support surface assembly 22 in different expanded states. FIG. 39A shows the support surface assembly 22 in an intermediate length state corresponding to an intermediate length of the support surface assembly 22. The support surface assembly 22 is made from a plurality of flat panel members that extend vertically relative to view direction shown and are intermittently bonded together to a flexible and expandable assembly. FIG. 39B shows the support surface assembly 22 in a compressed state corresponding to a reduced length of the support surface assembly 22 in which the separation distance between adjacent flat panel members is reduced. And FIG. 39C shows the support surface assembly 22 in an expanded state corresponding to a maximum length of the support surface assembly 22. By using a suitable number of flat panel members, the distance between adjacent flat panel members at locations between bonded areas can be kept below a distance suitable for ensuring that the support surface assembly 22 does not contract to a detrimental extent transverse to the expansion direction of the support surface assembly 22 when the support surface assembly 22 is expanded.
Any suitable material can be used to fabricate the support surface assembly 22. For example, the support surface assembly 22 can be made from polycarbonate strips, acrylic strips, and acrylic abrasion resistant strips. And any suitable method of manufacturing the support surface assembly 22 can be used. For example, separate strips can be joined via a suitable method (e.g., fusing, liquid welding, gluing). A form can be used to hold separate strips while they are joined. And the support surface assembly 22 can be fabricated by pouring a suitable material into a mold.
Any suitable fabrication method and material can be used to make the variable-planform shelving systems, tables, and clothes racks described herein. For example, suitable materials include steel, stainless steel, aluminum, galvanized steel, zinc, iron, titanium, and plastics (e.g., polycarbonate, acrylic, ABS, and HDPE). Suitable fabrication methods include, for example, stamping, water jetting, pouring, forming, metal casting, CNC machining, casting, and injection molding.
FIG. 40 shows a support surface assembly 220 that can be used in place of the support surface assembly 22. The support surface assembly 220 includes a plurality of slotted panels 222 having slots 224. Each of the slotted panels has a substantially rectangular planform with slightly curved outer edges 226 so as to present a smooth combined edge when the support surface assembly 220 is shaped to have a curved planform such as shown in FIG. 40. Each of the slots 224 is shaped to overlap an adjacent slot 224 of an adjacent panel in each of the various planform configurations of the support surface assembly 220. At each of the overlapping locations of the slots 224, a coupling element 230 as shown in FIG. 41 is used to constrain the adjacent panels relative to each other. As the support surface assembly 220 is reshaped into different planform shapes, the coupling element 230 slides within the slots 224 as dictated by the changing position of the overlapped location between the slots 224. Suitable panels of the slotted panels 222 can be tied to underlying frames of the variable support platform or to the base support platform with intermediate panels being free to adopt positions to provide a smooth transition between panels that are tied to the underlying frames. For example, one end panel of the support surface assembly 220 can be tied to the first frame 30 of the variable support platform 28, the opposite end panel of the support surface assembly 220 can be tied to the second frame 32 of the variable support platform 28, and the center panel of the support surface assembly 220 can be tied to the third frame 34 of the variable support platform 28, thereby leaving all the remaining untied panels to reposition to suitable locations consistent with the geometry of the slots 224 such that the support surface assembly 220 has a planform with smoothly curved edges.
