Therefore, it is ideal to provide a stand base that both provides adequate lateral support and is also compact for shipping and storage.
- Stand bases must also provide adequate vertical support to the display rack so that it may hold merchandise products having relatively large weight.
- disc-shaped bases are beneficial because they distribute the weight over a larger contact area relative to comparable leg-type bases where each leg alone must carry its share of the load.
- disc-shaped bases require more material than comparable leg-type bases, increasing the weight and cost of the base and overall stand which also makes packaging and shipping the stands more difficult.
- the legs may deform, crack or break prematurely. Weakness in any one of the legs can cause the stand base to fail to provide adequate vertical support, as well as adequate lateral support.
- the present invention provides a stand base comprising a central hub and a plurality of legs removably attached to the central hub. Each of the legs depends radially outward and downwardly from the central hub.
- the base stand is adapted to receive the central vertical mast of a display rack and provide both lateral and vertical support thereto.

- the width of the base widens with increased vertical load thereon, thereby increasing the amount of lateral support as a function of the load carried by the base.
- the plurality of legs support the central hub, central vertical mast and display apparatus off the floor during typical display rack loads.
- the high-load mode a sufficient amount of weight is placed on the display stand to force the legs to flex and the central hub to move downwardly towards the floor.
- the central hub will engage the floor to provide a majority of the vertical support of the merchandise stand.

- each of the plurality of arcuate legs 80 is attached to the central hub 40 at symmetrical positions.
- Each of the petals 46 of the cover 42 represent a position corresponding with each of the legs 80 , wherein the downwardly depending locking tab 50 and hollow T-shaped projections 64 exist for removably attaching the legs 80 to the central hub 40 .
- the legs are positioned below the central hub 40 , with the bottom of the hollow T-shaped projections 64 aligned with the T-shaped channel 120 defined in the horizontal top wall 114 of the notched portion 110 of the inner end 82 of the leg 80 .

- FIGS. 8 and 9 the stand base 30 is shown fully assembled and upright, having a central mast 22 (partially cut-away) extending vertically therefrom. It can be seen that one of the five legs 80 has been removed revealing the side of the central hub 40 .
- the legs 80 are generally arcuate in shape, and extend radially outwardly and downwardly from the central hub 40 ending at the leg's foot 86 .
- the bottom edges of the feet 86 are generally horizontal and engaging the floor 34 .
- the central mast 22 extends downwardly into the central hub's cavity 68 , i.e. through the aperture 44 in the cover 42 and the tubular sleeve 70 .
- the ring 76 of the tubular sleeve 70 prevents the mast 22 from extending further downward. It can be seen in FIG. 8 that the legs 80 extend downward from the central hub 40 a distance greater than the tubular sleeve 70 of the central hub 40 , as the tubular sleeve 70 is supported above the ground. The downward end 74 of the tubular sleeve 70 is supported above the ground a distance D, which is preferably 0.01 to 2 inches and most preferably 0.125 to 0.5 inches but is dependent on the overall size of the stand 20 , the base 30 and the weight of the merchandise to be displayed.
- D which is preferably 0.01 to 2 inches and most preferably 0.125 to 0.5 inches but is dependent on the overall size of the stand 20 , the base 30 and the weight of the merchandise to be displayed.
- the stand base uniquely provides increased lateral and vertical support to the stand as the weight of the stand and its contents increases.
- the legs 80 provide lateral support as they project radially outward from the central vertical support. Should the display stand 20 and its central mast 22 attempt to tip over, the legs 80 may bend slightly to accommodate some rotation, but will generally remain rigid to prevent the stand 20 and mast 22 from rotating more than a few degrees, thereby preventing the stand 20 from tipping.
- the legs 80 are generally of an arcuate shape extending outwardly and downwardly from the central hub 40 . This arcuate shape of the legs 80 can be seen in FIG. 8, which shows the stand base 30 supporting the central mast 22 .
- FIG. 8 represents a normal-load mode, wherein no or very little merchandise 28 , or merchandise having relatively low weight, are mounted to the display apparatus 24 . It can be seen that the legs 80 support the central hub 40 , including its tubular sleeve 70 , off the ground 34 . As a larger downward force is placed upon the central hub 40 (by virtue of more or heavier merchandise products) the legs 80 flex against their natural arcuate shape.
- the crisscrossing ribs 104 (FIG. 7) act against and restrict the flexure of the legs 80 , as does the natural resiliency of the material used to construct legs 80 .
- the legs 80 become somewhat straighter and the feet 86 80 move further apart, thereby increasing the width of the stand base 30 .
- the increased width provides increased lateral support for the display stand 20 .
- the legs 80 continue to flex against their natural arc, which is eventually limited by the tubular sleeve 70 contacting the floor 34 , as will be discussed in greater detail below with reference to FIG. 9 depicting the flexure of the legs 80 and a wider base 30 .
- the stand base 30 of the present invention provides increased lateral support to the display stand 20 as a function of increased load on the stand 20 resulting from larger downward forces placed on the central hub 40 of the stand base 30 causing the legs 80 to flex and widen the width of the base 30 .
- the stand base 30 provides vertical support in either a normal-load mode or a high-load mode.
- the legs 80 of the stand base 30 support the entire stand 20 off the ground, i.e. the legs 80 provide the vertical support.
- FIG. 9 shows the stand 20 in a high-load mode.
- the increased weight places a larger downward load on the central hub 40 .
- the normal-load mode the force was transferred from the hub 40 through to the legs 80 which provided adequate vertical support.
- the increased load causes the arcuate legs 80 to flex, but only to a pre-determined point.
- the tubular sleeve 70 of the central hub 40 is designed to engage the floor when the legs have flexed a given amount, providing additional vertical support. While a small amount of bending in the leg 80 is permitted, this does not harm the integrity of the leg which is also supported by the ribs 104 .
- the tubular sleeve 70 is designed to project downwardly from the cover 42 of the central hub 40 a distance somewhat less than the vertical distance the legs 80 project downwardly. In the high-load mode, the downward forced transmitted to the central mast 22 is transmitted directly downward through the tubular sleeve 70 which engages the floor 34 to provide adequate vertical support.
- the legs 80 no longer need to provide a majority of the vertical support, they continue to provide adequate lateral support to prevent the stand 20 from tipping. Further, the width of the base 30 will be at its greatest to provide increased lateral support to the stand 20 as previously described. It will be understood that other elements of the central hub, such as the cylindrical body, may project downward relative to the legs to engage the floor in the high-load mode without departing from the scope of the present invention.
- the stand base of the present invention provides a stand base having a wide breadth for superior lateral support, yet also may be disassembled and organized in a small and compact package for shipping or storing.
- the base reduces the amount of material used, yet provides excellent vertical as well as lateral support.
- the stand base delivers increased lateral support as the weight of the stand and its contents increases.
- the base provides vertical support in a normal-load mode and a high-load mode to protect the integrity of the legs and ensure adequate vertical and lateral support.

Abstract
Description
- The present relates generally to merchandise display racks or stands, and more particularly relates to a base for merchandise display stands.
- Common merchandise display racks or stands typically include a central vertical mast for attaching various display apparatus such as carousels, hooks, baskets or shelves. The vertical mast and display apparatus of these devices are supported off the ground by a base. Stand bases are generally of the disc-type or leg-type. For example, the disc-type bases typically comprise a circular disc-shaped object and can be seen in the 1999 Southern Imperial Catalog, pages 69-73. The leg-type bases generally include a plurality of legs projecting radially from a central point, such as in tripod, to provide lateral support to the display rack. Such bases are shown in the 1999 Southern Imperial Catalog,
pages - Both the disc-type and leg-type bases provide support to the stand, and more particularly to the vertical support, to prevent the stand from tipping. It is axiomatic that the further these discs or legs project radially outward, the more lateral support is provided for the rack. Discs and legs of a given size provide a certain amount of lateral support to the stand. Unfortunately, the wider the base becomes the more difficult and expensive packaging and shipping these stands become. Large bases require large packages, often resulting in a substantial amount of wasted packing space, inherently increasing shipping costs. Therefore, it is ideal to provide a stand base that both provides adequate lateral support and is also compact for shipping and storage.
- Stand bases must also provide adequate vertical support to the display rack so that it may hold merchandise products having relatively large weight. With regard to vertical support, disc-shaped bases are beneficial because they distribute the weight over a larger contact area relative to comparable leg-type bases where each leg alone must carry its share of the load. However, disc-shaped bases require more material than comparable leg-type bases, increasing the weight and cost of the base and overall stand which also makes packaging and shipping the stands more difficult. Yet, when large loads are placed on a leg-type base, the legs may deform, crack or break prematurely. Weakness in any one of the legs can cause the stand base to fail to provide adequate vertical support, as well as adequate lateral support.
- In light of the foregoing, it is an object of the present invention to provide a stand base having a wide breadth for superior lateral support, yet also may be organized in a small and compact package for shipping or storing.
- It also is an object of the present invention to provide a stand base that reduces the amount of material used, yet provides excellent vertical as well as lateral support.
- It is another object of the present invention to provide a stand base that delivers increased lateral support as the weight of the stand and its contents increases.
- It is yet another object of the present invention to provide a stand base that provides vertical support in two different load modes to protect the integrity of the legs and ensure adequate vertical and lateral support.
- In accordance with these objects the present invention provides a stand base comprising a central hub and a plurality of legs removably attached to the central hub. Each of the legs depends radially outward and downwardly from the central hub. The base stand is adapted to receive the central vertical mast of a display rack and provide both lateral and vertical support thereto.
- It is a feature of the present invention to detach the plurality of legs from the central hub and package the same together in a nested configuration that is compact for shipping and storage.
- It is another feature of the present invention to provide each of the plurality of legs with an arcuate shape so that the plurality of legs provide a natural resiliency and upward bias when a load is placed on the display stand.
- It is another feature of the present invention that the width of the base widens with increased vertical load thereon, thereby increasing the amount of lateral support as a function of the load carried by the base.
- It is yet another feature of the present invention to provide a stand base that provides vertical support in either a normal-load mode or a high-load mode. In the normal-load mode, the plurality of legs support the central hub, central vertical mast and display apparatus off the floor during typical display rack loads. In the high-load mode, a sufficient amount of weight is placed on the display stand to force the legs to flex and the central hub to move downwardly towards the floor. In the high-load mode the central hub will engage the floor to provide a majority of the vertical support of the merchandise stand.
- Other objects and advantages of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
- The accompanying drawings incorporated in and forming a part of the specification illustrate several aspects of the present invention, and together with the description serve to explain the principles of the invention. In the drawings:

Preferably, thebase 30 is molded from a generally rigid plastic which provides the necessary strength and elasticity of carrying out the invention. It can also be seen that thelegs 30 are identically shaped, such that when detached from thehub 40, they may be nested together in a compact configuration for shipping. - FIGS. 3, 4 and5 illustrate the
central hub 40 of thestand base 30 according to an embodiment of the invention. The upper surface of thecentral hub 40 is defined by a hood orcover 42. The cover includes acentral aperture 44 and is generally flower shaped, having a plurality ofpetals 46 corresponding with the plurality oflegs 80 removably attached to the central hub 40 (FIG. 2). Thepetals 46 are symmetrically arranged about theaperture 44, and hence the central axis of the stand defined by thecentral mast 22. Eachpetal 46 has an outercurved surface 48 having alocking tab 50 extending from adownward edge 52 of thecover 42 and thecurved surface 48. Each lockingtab 50 extends downwardly and includes anangled guide surface 54 and a flatgripping surface 56 which allow the plurality of legs to be removably attached to thecentral hub 40, as will be discussed in more detail herein. - The
central hub 40 further includes acylindrical body 60 connected to theunderside 43 of thecover 42 and extending downward therefrom. Thecylindrical body 60 is concentric with the central vertical axis. A plurality of elongate hollow T-shapedprojections 64 are connected to theouter surface 66 of thecylindrical body 60 and span the vertical length thereof, connecting to theunderside 43 of thecover 42. The hollow T-shapedprojections 64 are symmetrically spaced to correspond with the plurality oflegs 80, and each are sized to be received within a T-shaped channel (FIG. 6) on a leg when assembling thestand base 30. - The
central hub 40 further includes acavity 68 for receiving thecentral mast 22, thecavity 68 defined by atubular sleeve 70. Thetubular sleeve 70 has aninner surface 72 that meets thecover 42 to define thecavity 68 and theaperture 44. Thetubular sleeve 70 is connected to theunderside 43 of thecover 42 and extends downwardly therefrom. Thetubular sleeve 70 is sized to closely correspond with thevertical mast 22 of thestand 20 so that themast 22 may be received and retained within thetubular sleeve 70. As best seen in FIG. 5, theinner surface 72 includes a plurality of symmetrically spacedflats 73 to progressively reduce the effective inner diameter of thetubular sleeve 70. Theflats 73 taper as they extend downwardly. Theflats 73 reduce the area of contact between thecentral mast 22 and thetubular sleeve 70 making insertion and removal easier by virtue of less friction. It will be understood that the central hub may be adapted to receive a vertical support of any shape or structure, and may retain the same by various structures well know in the art such as pins, screws, latches, clamps, other friction fits and the like. - In the illustrated embodiment, a
downward end 74 of thetubular sleeve 70 includes a reduced diameter portion to prevent themast 22 from sliding all the way through thecavity 68 defined bytubular sleeve 70. As shown in FIGS. 4 and 5, aring 76 extends radially inward from theinner surface 72 of thetubular sleeve 70 proximate thedownward end 74 of thetubular sleeve 70. Thering 76 provides a horizontally disposedsurface 77 on which thecentral tubular mast 22 may rest. - As best seen in FIG. 4, the
tubular sleeve 70 is concentric with thecylindrical body 60 of thecentral hub 40. A plurality ofsupport fins 78 are connected to and project radially outward from anouter surface 71 of thetubular sleeve 70. The plurality ofsupport fins 78 correspond with the plurality of hollow T-shapedprojections 64 of thestand base 30. Thesupport fins 78 are radially aligned with the hollow T-shapedprojections 64 and connect theouter surface 48 of thetubular sleeve 70 to theinner surface 61 of thecylindrical body 60, thereby providing radial or lateral support to thecylindrical body 60 and T-shapedprojections 64 at positions corresponding to where thelegs 80 are attached to thecentral hub 40. - FIG. 6 shows one of the
legs 80 constructed according to an embodiment of the present invention. Theleg 80 is generally arcuate in shape and includes a firstinner end 82 and a secondouter end 84. The secondouter end 84 of eachleg 80 includes afoot 86. In the embodiment illustrated, thefoot 86 is semi-spherical to ensure even engagement of the floor in all directions, and in conjunction with the large size allows eachfoot 86 to provide support over at least 180° range. As can be seen in FIG. 7, theinside surface 87 of thesemi-spherical foot 86 includes aninner cylinder 88 connected to theinside surface 87 of thefoot 86. Afirst rib 90 connects theinner cylinder 88 and theinside surface 87 of thefoot 86 to provide lateral support. Similarly, asecond rib 92 connects theinner cylinder 88 to awall 94 projecting downwardly from thesecond end 84 of theleg 80, also to provide lateral support to theinner cylinder 88. Theinner cylinder 88 is adapted to receive the post of a caster, wheel, rubber pad, or the like, i.e. anything which might be interposed between the andfoot 86 and the ground. Alternatively, a post may be provided in the floor or other surface to which thestand 20 is to be placed upon in order to secure the base 30 to the floor and protect against unwanted rotation or sliding along the floor. - The
leg 80 is substantially hollow as defined by atop wall 98 and two substantiallyparallel sidewalls leg 80 is bowed, i.e. as one progresses from the firstinner end 82 to the secondouter end 84 the width of theleg 80 widens as it nears the middle and narrows again as it approaches a secondouter end 84. It can also be seen that a plurality of criss-crossingribs 104 are connected to the underside surfaces of thetop wall 98 andsidewalls leg 80. - Focusing on the
inner end 82 of theleg 80 best seen in FIGS. 6 and 7, theinner end 82 includes a notchedportion 110 that corresponds with thepetals 46 of the central hub'scover 42. The notchedportion 110 is defined by a curvedvertical wall 112 and a horizontaltop wall 114. It can be seen that the curvedvertical wall 112 is curved to correspond with the curvature of the cover'spetals 46, and specifically the petal's outer curved surface 48 (FIG. 3). The horizontaltop wall 114 includes arectangular aperture 116. Theaperture 116 corresponds with thelocking tab 50 projecting downwardly from the petals 46 (FIG. 3). It can also be seen that theinner end 82 of theleg 80 includes a curvedinner end wall 83. The curvedinner end wall 83 is curved to correspond with thecylindrical body 60 of the central hub 40 (FIGS. 3 and 4). The horizontaltop wall 114 and curvedinner end wall 83 cooperate with achannel wall 118 to define a T-shapedchannel 120 in the firstinner end 82 of theleg 80. The T-shapedchannel 120 corresponds with the hollow T-shapedprojections 64 projecting from thecylindrical body 60 of the central hub 40 (FIGS. 3 and 4). - As is readily apparent from the figures, each of the plurality of
arcuate legs 80 is attached to thecentral hub 40 at symmetrical positions. Each of thepetals 46 of thecover 42 represent a position corresponding with each of thelegs 80, wherein the downwardly dependinglocking tab 50 and hollow T-shapedprojections 64 exist for removably attaching thelegs 80 to thecentral hub 40. To attach thelegs 80, the legs are positioned below thecentral hub 40, with the bottom of the hollow T-shapedprojections 64 aligned with the T-shapedchannel 120 defined in the horizontaltop wall 114 of the notchedportion 110 of theinner end 82 of theleg 80. Theleg 80 is moved upwardly such that the hollow T-shapedprojections 64 enter and engage the T-shapedchannel 120. As the horizontaltop wall 114 of the notchedportion 110 approaches the central hub'scover 42, a downward end of thelocking tab 50 naturally enters therectangular aperture 116 in the horizontaltop wall 114. Theangled guide surface 54 of thelocking tab 50 forces the lockingtab 50 and outercurved surface 48 of thepetal 46 to deform radially inward as thelocking tab 50 extends further through therectangular aperture 116. When thedownward end 52 of thepetal 46 engages the horizontaltop wall 114 of the notchedportion 110, the flatgripping surface 56 of thelocking tab 50 has extended fully through therectangular aperture 116 and thelocking tab 50 and outercurved surface 48 of thepetal 46 naturally return to their original relaxed position. Thus, the flatgripping surface 56 engages the underside of the horizontaltop wall 114 of the notchedportion 110 to removably attach theleg 80 to thecentral hub 40. The outercurved surface 48 of thepetal 46 and the curvedvertical wall 112 fit closely together, as do the outer surface 62 of thecylindrical body 60 and the curvedinner end wall 83 of theleg 80. The hollow T-shapedprojections 64 extend fully through the T-shapedchannel 120 defined in theinner end 82 of theleg 80, thereby providing both vertical and radial support to the connection between theleg 80 andcentral hub 40. To remove theleg 80, one may reach between thesidewalls leg 80 to access thelocking tab 50 which may be depressed radially inward, so that the flatgripping surface 56 is vertically aligned with therectangular aperture 116 and can pass therethrough allowing theleg 80 to be removed from thecentral hub 40. - Turning to FIGS. 8 and 9, the
stand base 30 is shown fully assembled and upright, having a central mast 22 (partially cut-away) extending vertically therefrom. It can be seen that one of the fivelegs 80 has been removed revealing the side of thecentral hub 40. Thelegs 80 are generally arcuate in shape, and extend radially outwardly and downwardly from thecentral hub 40 ending at the leg'sfoot 86. The bottom edges of thefeet 86 are generally horizontal and engaging thefloor 34. Thecentral mast 22 extends downwardly into the central hub'scavity 68, i.e. through theaperture 44 in thecover 42 and thetubular sleeve 70. Thering 76 of thetubular sleeve 70 prevents themast 22 from extending further downward. It can be seen in FIG. 8 that thelegs 80 extend downward from the central hub 40 a distance greater than thetubular sleeve 70 of thecentral hub 40, as thetubular sleeve 70 is supported above the ground. Thedownward end 74 of thetubular sleeve 70 is supported above the ground a distance D, which is preferably 0.01 to 2 inches and most preferably 0.125 to 0.5 inches but is dependent on the overall size of thestand 20, thebase 30 and the weight of the merchandise to be displayed. - In accordance with an aspect of the present invention, the stand base uniquely provides increased lateral and vertical support to the stand as the weight of the stand and its contents increases. It will be readily recognized that the
legs 80 provide lateral support as they project radially outward from the central vertical support. Should thedisplay stand 20 and itscentral mast 22 attempt to tip over, thelegs 80 may bend slightly to accommodate some rotation, but will generally remain rigid to prevent thestand 20 andmast 22 from rotating more than a few degrees, thereby preventing thestand 20 from tipping. As previously described and as shown in the drawings, thelegs 80 are generally of an arcuate shape extending outwardly and downwardly from thecentral hub 40. This arcuate shape of thelegs 80 can be seen in FIG. 8, which shows thestand base 30 supporting thecentral mast 22. - The arcuate shape provides a natural resiliency and upward bias on the display stand. FIG. 8 represents a normal-load mode, wherein no or very
little merchandise 28, or merchandise having relatively low weight, are mounted to thedisplay apparatus 24. It can be seen that thelegs 80 support thecentral hub 40, including itstubular sleeve 70, off theground 34. As a larger downward force is placed upon the central hub 40 (by virtue of more or heavier merchandise products) thelegs 80 flex against their natural arcuate shape. The crisscrossing ribs 104 (FIG. 7) act against and restrict the flexure of thelegs 80, as does the natural resiliency of the material used to constructlegs 80. As a result of this bending, thelegs 80 become somewhat straighter and thefeet 86 80 move further apart, thereby increasing the width of thestand base 30. It will be readily understood by those having skill in the art that the increased width provides increased lateral support for thedisplay stand 20. As even more downward force is placed on thecentral hub 40, thelegs 80 continue to flex against their natural arc, which is eventually limited by thetubular sleeve 70 contacting thefloor 34, as will be discussed in greater detail below with reference to FIG. 9 depicting the flexure of thelegs 80 and awider base 30. It can therefore be seen that thestand base 30 of the present invention provides increased lateral support to the display stand 20 as a function of increased load on thestand 20 resulting from larger downward forces placed on thecentral hub 40 of thestand base 30 causing thelegs 80 to flex and widen the width of thebase 30. - In accordance with another aspect of the present invention, the
stand base 30 provides vertical support in either a normal-load mode or a high-load mode. When lightly loaded, thelegs 80 of thestand base 30 support theentire stand 20 off the ground, i.e. thelegs 80 provide the vertical support. FIG. 9 shows thestand 20 in a high-load mode. When large amounts of merchandise, or merely extremely heavy merchandise, are loaded onto thedisplay apparatus 24, the increased weight places a larger downward load on thecentral hub 40. In the normal-load mode, the force was transferred from thehub 40 through to thelegs 80 which provided adequate vertical support. In the high-load mode, however, the increased load causes thearcuate legs 80 to flex, but only to a pre-determined point. Whereas some prior art stands may deform, break or otherwise fail under such loads, thetubular sleeve 70 of thecentral hub 40 is designed to engage the floor when the legs have flexed a given amount, providing additional vertical support. While a small amount of bending in theleg 80 is permitted, this does not harm the integrity of the leg which is also supported by theribs 104. Thetubular sleeve 70 is designed to project downwardly from thecover 42 of the central hub 40 a distance somewhat less than the vertical distance thelegs 80 project downwardly. In the high-load mode, the downward forced transmitted to thecentral mast 22 is transmitted directly downward through thetubular sleeve 70 which engages thefloor 34 to provide adequate vertical support. Although thelegs 80 no longer need to provide a majority of the vertical support, they continue to provide adequate lateral support to prevent thestand 20 from tipping. Further, the width of the base 30 will be at its greatest to provide increased lateral support to thestand 20 as previously described. It will be understood that other elements of the central hub, such as the cylindrical body, may project downward relative to the legs to engage the floor in the high-load mode without departing from the scope of the present invention. - Therefore, one of ordinary skill in the art can readily see from the foregoing description that the stand base of the present invention provides a stand base having a wide breadth for superior lateral support, yet also may be disassembled and organized in a small and compact package for shipping or storing. The base reduces the amount of material used, yet provides excellent vertical as well as lateral support. The stand base delivers increased lateral support as the weight of the stand and its contents increases. Similarly, the base provides vertical support in a normal-load mode and a high-load mode to protect the integrity of the legs and ensure adequate vertical and lateral support.
