DETAILED DESCRIPTION

Described below are stackable shims for use in leveling gondola display fixtures in a retail store. Each shim includes a side having a recess and a side having a protrusion. The recess side of one shim receives the protruding side of another shim of the same type so as to stack multiple of the same shims together. In addition, the protruding side of each shim includes adjoining cavities or cells that provide the shim with greater load capability. When using the shim to level a gondola display fixture, the recess side faces up to receive a portion of the gondola display fixture or to face a portion of the gondola display fixture while the protruding side faces down to contact a floor. When using the shim to anchor a gondola display fixture to the floor, the protruding side faces up to receive an anchoring fastener and the recess side faces down to contact the floor.

FIG. 1 is a perspective view of a representative shim or floor shim 100 according to one embodiment. While shim 100 is described below in terms of use for a floor, it should be realized that shim 100 can be used in other ways including to fill small gaps or spaces between objects for object placement or between objects that are subject to wear. FIGS. 2-6 illustrate orthogonal views of shim 100 including a top view, a bottom view, a front view, a back view and a left side view, respectively. The opposing right side view of shim 100 is a mirror image of the FIG. 6 left side view. Shim 100 includes a main body 102 defined by a main body outer perimeter 104 and having a first side 105 that includes a first surface 106 and a second side 107 that includes an opposing second surface 108. In one embodiment, first side 105 is a top side of shim 100 and second side 107 is a bottom side of shim 100. In another embodiment, first side 105 is a bottom side of shim 100 and second side 107 is a top side of shim 100.

FIGS. 7 and 8 are sections views of shim 100 taken through the lines indicated in FIG. 3. As best illustrated in FIGS. 7 and 8, shim 100 includes a pocket or foot bed 110 located within main body outer perimeter 104 on first side 105 and a protrusion 112 located within main body outer perimeter 104 on second side 107. Protrusion 112 is defined by a protrusion outer perimeter 113 (FIG. 3). Pocket or foot bed 110 is recessed from first surface 106 by a pocket distance 114 to provide a support surface 116 and protrusion 112 protrudes from second surface 108 and terminates at an engaging surface 118 by a protrusion distance 119. Pocket distance 114 is substantially similar to protrusion distance 119 so that two identical shims 100 can be mated together so that an engaging surface 118 on one shim 100 contacts a support surface 116 on another shim 100 and second surface 108 on one shim 100 contacts first surface 106 on the other shim 100.

As illustrated in FIGS. 1, 3, 7 and 8, shim 100 also includes a plurality of geometrically shaped cells 120 located within protrusion outer perimeter 113 and being recessed from engaging surface 118. Each of the plurality of geometrically shaped cells 120 are recessed from engaging surface 118 by a cell distance 122. As illustrated in FIGS. 7 and 8, pocket distance 114 is less than cell distance 122.

In the embodiment illustrated in FIGS. 1-8, geometrically shaped cells 120 are triangular in shape and are grouped and arranged to form a latticework on engaging surface 118. Shim 100 includes groups 124 of four triangular-shaped cells 120. As denoted in FIG. 3, shim 100 includes eight groups 124a, 124b, 124c, 124d, 124e, 124f, 124g and 124h of four triangular-shaped cells. However, it should be realized that there can be any number of groups and any number of geometrically shaped cells (not just triangular cells) in each group. Between each geometrically shaped cell in each group and between each group forms the latticework on engaging surface 118. The combination of latticework and recessed cells provide shim 100 with an increased load capacity and in the case where multiple shims 100 are stacked together, a place for excess adhesive to be held.

As described and according to one embodiment, each of the groups 124a, 124b, 124c, 124d, 124e, 124f, 124g and 124h of cells 120 includes four triangular-shaped cells 120. A first two of the four of the triangular-shaped cells are substantially similar in dimension and a second two of the four of the triangular-shaped cells are substantially similar in dimensions. More specifically, the first two of the four triangular-shaped cells include three sides that are all substantially the same in dimension and are oriented at substantially equal angles from each other to form equilateral triangles. The second two of the four triangular-shaped cells include two sides that are substantially the same in dimension and two substantially equal angles to form isosceles triangles. In each group, the first two of the four triangular-shaped cells minor each other and the second two of the four triangular-shaped cells mirror each other such that triangular cells 120 are arranged symmetrically adjacent to each other.

Shim 100 also includes an anchoring area 126. Anchoring area 126 is centrally located on engaging surface 118 of protrusion 112 and therefore centrally located on second side 107 of main body 102. In other words, anchoring area 126 is in the middle of and surrounded by the groups of four triangular-shaped cells. Anchoring area 126 will be discussed in more detail below, but is the main location where shim 100 can receive an anchor for anchoring shim 100 to a floor.

Shim 100 also includes a flange 128 extending from a side of main body 102. Flange 128 includes a plurality of through holes 130a, 130b and 130c. While FIGS. 1-3 illustrate flange 128 with three through holes 130a, 130b and 130c, flange 128 can include any number. Flange 128 provides additional space for optionally anchoring shim 100 with anchor fasteners to a floor.

FIG. 9 is a perspective view of a gondola display fixture 200 that is being assembled and in need of shims for leveling. The gondola display fixture 200 illustrated in FIG. 9 is a gondola island run. However, it should be realized that the shim 100 described above can be used to level other types of gondola display fixtures including runs of gondola wall fixtures and gondola end caps as well as other types of display fixtures and other types of structural applications where leveling, gap filling or wear protection is needed. Since gondola display fixture 200 is a gondola island run, fixture 200 includes at least four base end brackets 250 (fixture 200 has eight), at least a pair of upright frame members 252 (fixture 200 has four), at least two base fronts 254 (fixture 200 has six), at least one center rail 258 (fixture 200 has three, but only two are visible) and at least one upright panel 260 (fixture 200 has six, but only two are illustrated).

For fixture 200, the two opposing base end brackets 250a and 250aa or 250b and 250bb are mounted to upright frame member 252a or 252b such that upright frame member 252a or 252b is located between two base end brackets 250a and 250aa or 250b and 250bb and is substantially vertically extending upwardly from base end brackets 250a and 250aa or 250b and 250bb. Each base front 254 connects two adjacent base end brackets 250a and 250b, 250b and 250b, 250aa and 250bb or 250bb and 250bb together. Each center rail 258 is supported by and extends between two upright frame members 252a and 252b or 252b and 252b. Upright panel 260 is located between and is supported by two upright frame members 252a and 252b or 252b and 252b and is additionally supported by one of the center rails 258. Each upright panel 260 is substantially vertically oriented and extends from a bottom rail to a top of the two upright frame members 252a and 252b or 252b and 252b. In addition, each base end bracket 250a, 250b, 250aa and 250bb includes a foot pad 262 (262a and 262aa in FIG. 12) located on a bottom of the base end bracket at a position distal from the upright frame member 252a or 252b that the base end bracket is mounted to.

As part of installing fixture 200, fixture 200 is leveled by identifying which of the assembled base end bracket(s) and corresponding upright frame member is the highest. Shims are then placed under the other base end brackets and corresponding upright frame members to bring the other base end brackets and corresponding upright frame members up to the same level as the highest base end bracket(s) and corresponding upright frame member. For example, fixture 200 has two end upright frame members 252a located at opposing ends and two intermediate upright frame members 252b located between the end upright frame members 252a. If the two intermediate upright frame members 252b are higher than the end upright frame members 252a, then the assembled end upright frame members 252a and corresponding intermediate base end brackets 250a and 250aa will have to be raised to match the height of the intermediate upright frame members 252b.

In the above example, before introducing a shim or a plurality of shims that are arranged into a stack to fixture 200, it needs to be determined how much (or how high) each end upright frame member 252a in the run needs to be raised to align horizontally with each intermediate upright frame member 252b in the run. After determining the height needed, one or more shims 100 can be prepared accordingly.

According to one embodiment, FIG. 10 is a perspective view of a portion of gondola display fixture 200 being leveled with shim structures or shim stacks 300a, 300b and 300c each containing multiple of the representative shim 100 illustrated in FIG. 1. Representative shim 100, which is illustrated in FIGS. 1-8 in detail, is stackable or capable of being mated with other like shims 100. In exemplary FIG. 10, it was determined that each shim structure or stack 300a, 300b and 300c needs four representative shims 100 to level the illustrated portion (i.e., intermediate base end brackets 250a and 250aa and intermediate upright frame member 252a) of fixture 200. As illustrated, shim structure or stack 300a includes identical shims 100a, 100b, 100c and 100d. Shim structure or stack 300b includes identical shims 100e, 100f, 100g and 100h. Shim structure or stack 300c includes identical shims 100i, 100j, 100k and 100. In addition, each shim 100a, 100b, 100c and 100d is identical to each shim 100e, 100f, 100g and 100h as well as identical to each shim 100i, 100j, 100k and 100m.

However, in other instances, it may be that each shim structure 300a, 300b and 300c only requires a single representative shim 100 or other amount of shims 100 to level fixture 200. With reference back to FIGS. 1-8 and in a single shim embodiment, shim structure 300a can include single floor shim 100 positioned under foot pad 262 of fixture 200 such that foot bed 110 receives foot pad 262 and engaging surface 118 is in contact with the floor. Shim structure 300c can include a single floor shim 100 positioned under foot pad 262 of fixture 200 such that foot bed 110 receives foot pad 262 and engaging surface 118 is in contact with the floor. Shim structure 300b can include a single floor shim 100 positioned under upright frame member 252a of fixture 200 such that foot bed 110 faces a bottom of upright frame member 252a and engaging surface 118 is in contact with the floor.

With reference back to the embodiment illustrated in FIG. 10, FIG. 11 illustrates an enlarged section view of shim structure or stack 300a including all four shims 100a, 100b, 100c and 100d. As discussed above, it is possible that shim structure or stack 300a, shim structure or stack 300b and shim structure or stack 300c may include only one shim 100a, one shim 100e and one shim 100i, respectively. In FIG. 11, the at least one shim 100a (as would 100e and 100i for shim structures or stacks 300b and 300c) includes a main body 102a having a first side 105a having a foot bed 110a with a support surface 116a and a second side 107a having a protrusion 112a that terminates at an engaging surface 118a.

In the alternative and as illustrated in FIG. 11, shim stack 300a can include not only shim 100a, but also shims 100b, 100c and 100d. Each additional shim 100b, 100c and 100d includes a main body (102b, 102c, 102d) including a first side (105b, 105d, 105d) having a foot bed (110b, 110c, 110d) with a support surface (116b, 116c, 116d) and a second side (107b, 107c, 107d) opposite the first side (105b, 105c, 105d) and including a protrusion (112b, 112c, 112d) that terminates at an engaging surface (118b, 118c, 118d).

In this multiple shim stack embodiment, engaging surface 118a of uppermost shim 100a mates with foot bed 110b and contacts support surface 116b, engaging surface 118b of intermediate shim 100b mates with foot bed 110c and contacts support surface 116c and engaging surface 110c of intermediate shim 100c mates with foot bed 110d and contacts support surface 116d of lowermost shim 100d. The stack of mated shims 100a, 100b, 100c and 100d are positioned under foot pad 262a of fixture 200 such that foot bed 110a of uppermost shim 100a receives foot pad 262a by placing foot pad 262a in contact with support surface 116a and engaging surface 118d of lowermost shim 100d in contact with the floor.

Further and as discussed in regards to FIGS. 1-8, protrusions 112a, 112b, 112c and 112d on each shim 100a, 100b, 100c and 100d include a plurality of adjoining cavities (like adjoining cavities 120 illustrated in FIGS. 1, 3, 7 and 8) recessed from engaging surfaces 118a, 118b, 118c and 118d, respectively. Adjoining cavities provide shims 100a, 100b, 100c and 100d with greater load capability. While a stack of shims need not be mechanically fastened together other than mated together as illustrated in FIG. 11, each stack of shims 300a, 300b and 300c can be further secured together using adhesive. More specifically, adhesive (not illustrated) can be placed between engaging surface 118a and support surface 116b, between engaging surface 118b and support surface 116c and between engaging surface 118c and support surface 116d such that shims 100a, 100b, 100c and 100d are all adhered together. In this way, adjoining cavities in protrusions 112a, 112b and 112c provide space for excess adhesive to be held.

With reference back to FIG. 10 and in regards to FIG. 12, which illustrates a side view of FIG. 10, shim structure 300a of multiple shims 100a, 100b, 100c and 100d is positioned under foot pad 262a of end base end bracket 250a, shim structure 300b of multiple shims 100e, 100f, 100g and 100h is positioned under a bottom of end upright frame member 252a and shim structure 300c of multiple shims 100i, 100j, 100k and 100m is positioned under a foot pad 262aa of end base end bracket 250aa. In this way, foot bed 110a of uppermost shim 100a receives foot pad 262a, the foot bed of uppermost shim 100e at least faces the bottom of end upright frame member 252a, the foot bed of shim 100i receives foot pad 262aa and engaging surface 118d of lowermost floor shim 100d, the engaging surface of lowermost floor shim 100h and the engaging surface of lowermost shim 100m all contact the floor.

Uppermost shim 100e in shim structure or stack 300b does not necessarily engage with upright member 252a in an unloaded state. As illustrated in FIG. 12, a gap is desirable to prevent fixture 200 from rocking back and forth prior to being loaded with merchandise. Upon being loaded, upright frame member 252a will contact shim structure or stack 300b or in other words, the foot bed of uppermost floor shim 100e will receive the bottom of upright frame member 252a.

FIG. 13 is a perspective view of fixture 200 having been leveled with shin structures or shim stacks 300a, 300b and 300c and further being anchored to the floor. According to one embodiment, fixture 200 includes at least one anchor bracket 270 for use in anchoring fixture 200 to the floor. In FIG. 13, fixture 200 includes anchor bracket 270a and anchor bracket 270b. A first end of each anchor bracket 270a and 270b includes a flange 272a (only the flange of anchor bracket 270a is shown) that fits within an aperture 251a (only the aperture in base end bracket 252a is shown) of base end brackets 250a and 250aa and is thereby coupled to each base end bracket 250a and 250aa. A second end of each anchor bracket 270a and 270b includes a flange 274a and 274b with a hole for receiving an anchoring fastener 276a and 276b.

One or more shims 100 are assembled into shim structures or stacks to fit under flanges 274a and 274b of anchor brackets 270a and 270b. Each shim in the assembled shim structures or shim stacks are identical to each shim in shim structures or shim stacks 300a, 300b and 300c. For example and as illustrated in FIG. 13, shim structures or shim stacks 300d and 300e are prepared for fitting under anchor bracket 270a and 270b. The number of shims in shim structures or shim stacks 300d and 300e are selected so that anchor bracket 270 remains as level as possible when secured to the floor through the shim structure or stack. In FIG. 13, shim stack structure or stack 300d includes shims 100n, 100o, 100p and 100q and shim structure or stack 300e includes shims 100r, 100s, 100t and 100u. Shims 100n, 100o, 100p and 100q mate together in the same manner as the shims in shim structure or stack 300a illustrated in FIG. 11 and shims 100r, 100s, 100t and 100u mate together in the same manner as the shims in shim structure or stack 300a illustrated in FIG. 11.

Rather than an engaging surface of a second side of lowermost shims 100q and 100u contacting the floor, a first side of lowermost shims 100q and 100u contacts the floor. In other words, relative to shim stacks 300a, 300b and 300c, shim stacks 300d and 300e are inverted so that an engaging surface 118 of a second side 107 of uppermost shims 100n and 100r face up. Each shim in shim stacks 300d and 300e mate together and are adhered together as described with reference to FIG. 11. Shim stack 300d is positioned under flange 274a of anchor bracket 270a (with engaging surface 118 of uppermost shim 100n facing up) and shim stack 300e is positioned under flange 274b of anchor bracket 270b (with engaging surface 118 of uppermost shim 100r facing up).

A hole is drilled through each shim in shim structures or stacks 300d and 300e at anchoring area 126 (described with reference to FIGS. 1 and 3) to accommodate either anchoring fastener 276a or 276b. Anchoring fasteners 276a and 276b will couple base end bracket 250a or 250aa to the floor by extending through the stack of shims at the anchoring area 126 and by embedding an end of fastener 276a or 276b into the floor. In accordance with one embodiment, fasteners 276a and 276b include a bolt with two threaded ends, a nut and a washer. One of the threaded ends of each bolt passes through the stack of shims 300d or 300e and is screwed to the floor. A washer is placed over the other threaded end of each bolt and a nut is threaded onto the bolt and is tightened to secure flange 274a or 274b and the base end bracket 250a or 250aa to the shims, which are secured to the floor.
