DESCRIPTION OF EMBODIMENTS

[0034] The embodiments provide systems and methods that facilitate universal compatibility of shelves across multiple refrigerated display case configurations. The systems and methods utilize a bracket design with stepped slot geometries and adjustable separation between brackets of the shelf to accommodate different upright thicknesses, hole patterns, and upright separation from various original equipment manufacturers (OEMs). This allows a single shelf model to fit cases with different upright standards and configurations, reducing inventory complexity for retailers with diverse refrigerated case fleets while maintaining proper alignment and stability across various configurations.

[0035] The example embodiments described herein make use of uprights. As used herein, upright may include any vertical structural member that provides support and mounting points for shelves or other components. As examples, uprights may include metal posts, rails, or panels with regularly spaced holes, slots, or other attachment features for securing shelves at various heights within the case.

[0036] The exemplary embodiments described herein make use of brackets. As used herein, bracket may include any structural component designed to connect a shelf to an upright. As examples, brackets may include metal pieces with projecting members, slots, hooks, or other features that engage with corresponding elements on the uprights to secure the shelf in place.

[0037] The example embodiments described herein make use of slots. As used herein, slot may include any opening, cutout, or recess in a bracket or other component designed to receive or engage with a portion of an upright or other structural element. As examples, slots may include rectangular openings with uniform or varying widths, L-shaped cutouts, or other geometries that allow for secure attachment while potentially accommodating different upright thicknesses or configurations.

[0038] FIG. 1 illustrates a perspective view of a refrigerated display case 100, according to an embodiment. The refrigerated display case 100 comprises a cabinet structure with an open front for product display and access. Multiple shelves 104 are arranged vertically within the case 100, providing tiered storage and display areas for refrigerated products. These shelves 104 are supported by multiple uprights, including an upright 102 visible at the center of the case.

[0039] The configuration shown in FIG. 1 demonstrates the typical environment in which the universal shelf system may be implemented. Refrigerated display cases like the one illustrated may come in various sizes and configurations from different manufacturers. Each case may have unique dimensions and unique upright designs. Cases may be designed with uprights having different thicknesses and widths, as well as different hole configurations and hole patterns. For purposes of clarity, the term upright standard (or simply standard) refers to a configuration of the upright, including a particular thickness (or gauge), width, hole pattern, hole dimension, or other suitable features of the upright that may be standardized for a given display case or other product. Thus, it may be appreciated that different manufacturers may utilize case designs with different upright standards, and that some manufacturers may even use different standards across different product lines. Moreover, within different cases, the separation distance between uprights (and thus the necessary separation distance between left and right mounting brackets on a shelf) may also vary.

[0040] FIGS. 2 and 3 illustrate different views of a shelf 200 for use in a refrigerated display case. FIG. 2 provides a perspective view of the shelf 200, while FIG. 3 shows an isometric view of the same shelf 200. Referring to FIGS. 2-3, the shelf 200 comprises several components, including a main panel 202, a molding component 204, a left bracket 206, and a right bracket 208. The main panel 202 forms the primary surface of the shelf 200. The main panel 202 extends from a shelf upper side 220 to a shelf lower side 222, and from a shelf left side 224 to a shelf right side 226.

[0041] The molding component 204 is disposed at a front end of the shelf 200, providing a finished edge. In some cases, the molding component 204 may function as a price tag molding.

[0042] The left bracket 206 is positioned at the shelf left side 224 and is designed to engage with the upright supports of a refrigerated display case. The right bracket 208 is positioned at the shelf right side 226 and is designed to engage with the upright supports of a refrigerated display case.

[0043] FIGS. 3 and 4 show views of the lower side 222 shelf 200, according to an embodiment. As seen in FIGS. 3 and 4, the lower side 222 of shelf 200 includes three main channels: a first channel 302, a second channel 304, and a third channel 306. These channels extend across the width of the shelf 200 (from the shelf left side 224 to the shelf right side 226) and may provide structural reinforcement to the main panel 202. The main channels are shown as C-shaped channels in the illustrated embodiment. However, in other embodiments, these channels may have different shapes or configurations. For example, the channels may have U-shaped, V-shaped, rectangular, or other geometric profiles. The specific shape of the channels may be selected based on factors such as structural requirements, manufacturing considerations, or compatibility with other components of the shelf assembly. In some cases, the channel shape may be optimized to enhance the strength-to-weight ratio of the shelf or to facilitate assembly and disassembly. Moreover, in other embodiments, the number of channels used could vary according to structural requirements. The flexibility in channel design allows for adaptation to various manufacturing processes and material choices while maintaining the functional benefits of providing structural reinforcement to the main panel 202.

[0044] In some embodiments, the main channels may be welded to the main panel, providing a secure attachment and structural integrity to the shelf assembly. Alternatively, in other embodiments, the main channels may be integrally formed with the main panel. The choice between welded attachment and integral formation may depend on factors such as production methods, material selection, and specific performance requirements of the shelf system.

[0045] The shelf 200 may incorporate a width adjustment mechanism to accommodate various refrigerated display case configurations. This adjustability feature allows a single shelf model to fit cases of different widths, potentially reducing inventory complexity for retailers with diverse refrigerated case fleets. The width adjustment may be achieved through the interaction between the main panel 202 and the left and right brackets (left bracket 206 and right bracket 208). In some aspects, the brackets may be designed to move relative to the main panel, allowing the separation distance between the brackets to be increased or decreased as needed. Thus, while the overall width of the shelf, determined by the width of the main panel 202, may be fixed, the relative separation (or width) between brackets may be adjusted to accommodate different widths between uprights in a display case. This adjustability may enable the shelf to maintain proper alignment and stability across various case dimensions from different original equipment manufacturers (OEMs).

[0046] In some embodiments, the widthwise adjustment of the brackets may be accomplished using slide channels that are mounted to the brackets and may be inserted into and slide relative to the main channels. The left bracket 206 and the right bracket 208 may each include a set of slide channels 320 that correspond to the main channels on the shelf lower side 222. As shown in FIG. 4, the left bracket 206 may be attached to a first slide channel 402, a second slide channel 404, and a third slide channel 406, while the right bracket 208 may be attached to a fourth slide channel 412, a fifth slide channel 414, and a sixth slide channel 416.

[0047] These slide channels may be designed to engage with the main channels, allowing for adjustable positioning of the brackets relative to the main panel 202. The slide channels on the left bracket 206 and the right bracket 208 may be designed to insert into opposing ends of the main channels on the shelf lower side 222, allowing for widthwise adjustment of the brackets.

[0048] On the left side, the first slide channel 402, second slide channel 404, and third slide channel 406 of the left bracket 206 may insert into one end of the first channel 302, second channel 304, and third channel 306 respectively. Similarly, on the right side, the fourth slide channel 412, fifth slide channel 414, and sixth slide channel 416 of the right bracket 208 may insert into the opposite end of the first channel 302, second channel 304, and third channel 306 respectively. These slide channels may be sized and shaped to fit snugly within the corresponding main channels while still allowing for sliding movement.

[0049] In some embodiments, the brackets may be constrained to slide between a position in which they are pressed against the ends of the main channels and a position in which they are pressed against portions of the main panel. For example, in FIG. 4, the movement of left bracket 206 is constrained to the left by main panel left flange 430 and to the right by the (leftmost) ends of first channel 302, second channel 304 and third channel 306. Likewise, the movement of right bracket 208 is constrained to the right by main panel right flange 432 and to the left by the (rightmost) ends of first channel 302, second channel 304 and third channel 306. It may be appreciated that the dimensions of the corresponding slide channels may be such that each bracket encounters a corresponding flange of the main panel 202 before the slide channels escape the main channels. In other words, the width of the slide channels is sufficiently greater than the separation distance between the ends of the main channels and the main panel flanges. For example, as shown in FIG. 4, a width 450 of slide channel 412 (part of which is shown in phantom) is greater than a separation distance 452 between the ends of the main channels (for example, end 460 of main channel 306) and the panel right flange 432.

[0050] This configuration may allow the left bracket 206 and the right bracket 208 to slide inward or outward along the main channels, adjusting the width between the brackets. The main channels may act as guides for the slide channels, ensuring smooth and controlled movement of the brackets. Moreover, this configuration allows the brackets to slide to different positions while preventing the brackets from being disconnected from the shelf 200, which could happen if the slide channels were to escape the main channels.

[0051] In some aspects, the slide channels and main channels may include features such as ridges, grooves, or detents that help secure the brackets at specific width settings while still allowing for adjustment when needed.

[0052] The sliding channel arrangement may allow for a wide range of width adjustments while maintaining the structural integrity of the shelf. The sliding mechanism may also be designed to be easily operated, allowing for quick and tool-free width adjustments in the field. Additionally, this design may minimize the number of separate components required for width adjustment, improving reliability and simplifying maintenance.

[0053] FIG. 5 illustrates an isometric view of a portion of a shelf structure. The structure comprises a main panel 202 which forms the primary horizontal surface of the shelf. The main panel 202 may include side portions for structural support. In the exemplary embodiment shown in FIG. 5, the main panel 202 includes main panel flange portions 502 that may be formed by bending down a sheet of metal or other suitable material for the main panel. These flange portions 502 are created by bending the material of the main panel 202 downward at the edges.

[0054] The main panel flange portions 502 may serve multiple purposes. They may reinforce the edges of the shelf, increasing its overall structural integrity and load-bearing capacity. Additionally, the flange portions 502 may provide a finished appearance to the edges of the shelf. In some aspects, as already discussed, the flange portions 502 may also function as guides or stops for the sliding mechanism of the brackets, helping to constrain the widthwise movement of the brackets and prevent them from disengaging from the main channels.

[0055] FIGS. 6 and 7 illustrate different views of a right bracket 208 for a shelf assembly. FIG. 6 shows an isometric view of the right bracket 208 with attached slide channels, while FIG. 7 provides an view of the same bracket with the slide channels removed.

[0056] The right bracket 208 comprises an elongated body with several features. Along the length of the bracket 208, there are three slide channels: a fourth slide channel 412, a fifth slide channel 414, and a sixth slide channel 416. These slide channels are designed to engage with the main channels of the shelf, allowing for adjustable positioning of the bracket relative to the main panel.

[0057] In some embodiments, the slide channels may be fixedly attached to the bracket. One method of attachment may involve welding the slide channels to the bracket. As shown in FIG. 7, the right bracket 208 may include slots corresponding to each slide channel. For example, the bracket 208 may have a first slot 712, a second slot 714, and a third slot 716. Each slide channel may include tabs that can be inserted through these slots. For instance, the fourth slide channel 412 may have a first tab 740 and a second tab 742. One of these tabs (such as tab 742) may be inserted through the first slot 712, and then welded in place to securely attach the slide channel to the bracket.

[0058] This welding method may provide a strong and durable connection between the slide channels and the bracket. It may allow for precise positioning of the slide channels on the bracket while ensuring they remain firmly in place during use and adjustment of the shelf.

[0059] In other embodiments, however, the slide channels may be integrally formed with the bracket. This approach may involve manufacturing the bracket and slide channels as a single piece, potentially through processes such as extrusion, casting, or injection molding, depending on the material used.

[0060] The choice between welded attachment and integral formation may depend on various factors, including manufacturing capabilities, cost considerations, material properties, and specific performance requirements of the shelf assembly. Both methods may provide secure attachment of the slide channels to the bracket, enabling the adjustable width functionality of the shelf system.

[0061] FIG. 8 illustrates a side view of a right bracket 208 for a shelf. The right bracket 208 comprises a bracket upper edge 802 and a bracket lower edge 804. The bracket upper edge 802 extends horizontally from a forward end 812 of the bracket to a rearward end 810. The bracket lower edge 804 has a curved profile, starting at a lower point near the rearward end 810 of the bracket and gradually rising towards the forward end 812. The curved profile of the bracket lower edge 804 may contribute to the overall strength and stability of the bracket while minimizing material usage. The curvature may also allow for better clearance when installing or adjusting the shelf in a refrigerated display case.

[0062] The rearward end 810 may include features for attaching the bracket to an upright in a refrigerated display case, as best shown in the enlarged view of FIG. 9.

[0063] The bracket design may incorporate features to accommodate different upright standards used by various refrigerated display case manufacturers. This adaptability may be achieved through the use of specialized geometries in the portions of the bracket that interface with the uprights. In some aspects, the bracket may include projecting members with slots or openings of varying dimensions. These slots may be designed with stepped profiles, enabling a single bracket to fit multiple upright hole configurations and upright thicknesses for different upright standards. This approach may allow the bracket to be compatible with a wide range of refrigerated display case models without requiring separate bracket designs for each upright configuration. The geometry of the bracket portions that insert through the upright holes may also be designed to provide a secure connection while allowing for easy installation and removal of the shelf. This versatility in bracket design may contribute to the overall adaptability of the shelf system, reducing inventory complexity for retailers with diverse refrigerated case fleets.

[0064] In some embodiments, the bracket may include three projecting members designed to interface with the upright of a refrigerated display case. Two of these projecting members may be configured to engage and be retained within the upright, providing primary points of attachment for the shelf. These two projecting members may include slots or openings with varying dimensions to accommodate different upright thicknesses and hole configurations. The third projecting member may extend from the lower portion of the bracket and may be used to facilitate stability, load bearing, and leveling of the shelf. The arrangement of these three projecting members may allow for secure attachment, proper weight distribution, and adjustable positioning of the shelf within various refrigerated display case configurations.

[0065] FIG. 9 illustrates a detailed view of the rearward end 810 of the bracket. The bracket includes two primary projecting members, a first projecting member 902 and a second projecting member 904, which are designed to engage with the upright. The bracket also includes a third projecting member 906 and an adjacent stepped interface 908, which are discussed in further detail below.

[0066] Each of the projecting member 902 and the projecting member 904 incorporates two slots. On the first projecting member 902, there is slot 920 and slot 922, while on the second projecting member 904, there is slot 930 and slot 932. Each of these slots may be shown with an open side on a lower portion of the corresponding projecting member. For example, the open side of slot 920 corresponds to lower projecting member edge 982. This configuration may ensure that weight applied downwardly on the shelf acts to keep each slot engaged with a corresponding portion of an upright, as discussed in further detail below.

[0067] As best shown in the enlargement of FIG. 10, slot 922 and slot 932, which are positioned closer to the rearward end 810, are oriented in a more vertical alignment. In particular, slot 922 and slot 932 may be oriented in a direction that is generally parallel with the edge of rearward end 810. Slot 920 and slot 930, located further from the rearward end 810, are rotated at an angle relative to slots 922 and 932 and the rearward end 810. Specifically, slot 920 and slot 930 are oriented at an angle 1040 with respect to the orientation of slot 922 and slot 932.

[0068] The positioning and orientation of these slots serve different purposes in shelf installation. Slot 922 and slot 932, being closer to the rearward end 810 and more vertically aligned, may be used to attach the shelf in a generally horizontal configuration. That is, in a configuration in which main panel 202 is generally horizontal. This arrangement may provide a stable, level surface for displaying products in the refrigerated case.

[0069] On the other hand, slot 920 and slot 930, which are angled and positioned further from the rearward end 810, may allow for the installation of the shelf at an inclined orientation. This angled configuration may be useful in certain display scenarios, and in some cases may be used to improve product visibility.

[0070] The dual-slot design on each projecting member may provide flexibility in shelf installation, allowing for both horizontal and angled orientations to accommodate various merchandising needs. This versatility may enable retailers to customize their product displays within the same refrigerated case, potentially enhancing visual appeal and accessibility of items for customers.

[0071] In some embodiments, the vertical slots (slot 922 and slot 932) and the angled slots (slot 920 and slot 930) may generally have similar geometries. However, in other embodiments, the geometries of different slots could vary to accommodate specific upright designs or to provide additional functionality.

[0072] As also seen in FIG. 10, the first projecting member 902 extends further from the rearward end 810 than the second projecting member 904. This difference in extension is illustrated by distance 1032 and distance 1030, respectively. The projecting members also feature varying widths in different portions. The first projecting member 902 comprises a first portion 1002 with a first portion width 1003, and a second portion 1004 with a second portion width 1005. In the exemplary embodiment, first portion width 1003 is substantially smaller than second portion width 1005 such that the spacing between slot 920 and slot 922 is greater than the distance from first slot 920 to an end of first projecting member 902. Similarly, the second projecting member 904 includes a first portion 1012 with a first portion width 1013, and a second portion 1014 with a second portion width 1015. In the exemplary embodiment, first portion width 1013 is substantially smaller than second portion width 1015 such that the spacing between slot 930 and slot 932 is greater than the distance from first slot 930 to an end of second projecting member 904.

[0073] The varying widths and extensions of the projecting members may allow the bracket to engage securely with different upright configurations while maintaining proper alignment and stability.

[0074] As discussed, the slots of each projecting member may have a geometry that is configured to engage with different upright standards, including different upright wall thicknesses and hole configurations.

[0075] FIG. 11 illustrates a detailed orthogonal view of a portion of a bracket, specifically focusing on the second slot 922. The second slot 922 comprises two distinct portions: a first slot portion 950 and a second slot portion 952. First slot portion 950 is disposed closest to a lower edge 1102 of the first projecting member 902 and is open on lower edge 1102. Second slot portion 952 is disposed inwardly of first slot portion 950 with respect to lower edge 1102 such that any portion of an upright inserted into second slot portion 952 must also extend through first slot portion 950.

[0076] Each slot portion may have a generally rectangular shape. That is, the opposing walls of the slot portions may be substantially parallel to each other and may also be substantially straight without any curvature except at the corners. For example, as shown in FIG. 11, surface 1110, surface 1112, surface 1114, surface 1116, and surface 1118, which collectively bound slot 922 are all substantially straight and meet at substantially right angles. This configuration may allow for a secure fit with upright portions of various thicknesses. The rectangular shape and parallel surfaces may provide consistent contact points along the length of the slot, potentially enhancing the stability of the connection between the bracket and the upright. In some cases, the parallel surfaces may also facilitate easier insertion and removal of the bracket from the upright, while maintaining a snug fit during use.

[0077] To accommodate different upright standards, including different upright wall thicknesses, each slot portion may have a different height and width. As seen in FIG. 11, the first slot portion 950 has a first height 951, which is less than the second height 953 of the second slot portion 952.

[0078] At the junction between the two rectangular portions, there is a stepped corner 954. This stepped corner 954 forms a transition between the wider first slot portion 950 and the narrower second slot portion 952. Specifically, the first slot portion 950 has a first width 956, while the second slot portion 952 has a second width 957. In some aspects, the first width 956 may be greater than the second width 957, creating a stepped profile that narrows from bottom to top.

[0079] This stepped geometry of the second slot 922 may accommodate of different upright thicknesses. The wider first slot portion 950 may receive thicker uprights, while the narrower second slot portion 952 may accommodate thinner uprights, providing versatility in the bracket's compatibility with various refrigerator case designs. It may be appreciated that the stepped configuration not only accommodates uprights of different thicknesses, but ensures the proper vertical placement of the bracket according to the upright standard. Specifically, uprights with widths accommodated by first slot portion 950 may be prevented from sliding into second slot portion 952, thereby ensuring the bracket is set at the proper height for a given upright such that the adjacent projecting member 904 and the projecting member 906 may also be received in holes of the upright. By contrast, if slot 922 had a uniform width to accommodate the thickest upright walls the bracket might fall to a vertical position that is incompatible with the other projecting members fitting into corresponding holes for some upright hole sizes and vertical spacings.

[0080] FIG. 12 illustrates a sectional view of a lower corner portion of the bracket 208. The lower corner portion includes the third projecting member 906 and the adjacent stepped interface 908, which facilitate attaching the bracket to an upright in a refrigerated display case.

[0081] The third projecting member 906 may be designed to insert through a hole in an upright, providing load-bearing support and facilitating leveling of the shelf. This projecting member may extend from the lower portion of the bracket and may have a shape and size optimized for engagement with various upright configurations.

[0082] In an exemplary embodiment, third projecting member 906 comprises a finger-like projection with a substantially straight upper surface 1230, a substantially straight lower surface 1212 and a convex surface 1232 connecting upper surface 1230 and lower surface 1212. That is, unlike the first and second projecting portions, third projecting member 906 does not have any slots or other concave portions.

[0083] Adjacent to the third projecting member 906 is the stepped interface 908. This interface may accommodate different upright standards used by various refrigerated display case manufacturers. The stepped design of the interface 908 may allow for fine adjustments in the positioning of the bracket relative to the upright, enabling precise leveling of the shelf.

[0084] The stepped interface 908 comprises several surfaces that form a series of steps that begin from lower surface 1212 of third projecting member 906. More specifically, these surfaces may be engaging surfaces configured to engage (that is contact, rest upon, or otherwise interface with) portions of an upright. Moving down from the lower surface 1212, the stepped interface 908 includes a first vertical step surface 1202, followed by a first horizontal step surface 1204. Below these are a second vertical step surface 1206 and a second horizontal step surface 1208. The stepped interface 908 culminates with a third vertical step surface 1210 which connects to lower edge 804 of bracket 208.

[0085] This multi-step configuration may allow the bracket to adapt to different upright designs and thicknesses. Depending on the specific upright standard, different surfaces of the stepped interface may engage with the upright. For example, in some upright configurations, the lower surface 1212 of projecting member 906 and first vertical surface 1202 may contact a portion of the upright. In other configurations, the first horizontal surface 1204 and the second vertical surface 1206 may contact a portion of the upright. In other configurations, the second horizontal surface 1208 and the third vertical surface 1210 may contact a portion of the upright.

[0086] The versatility provided by the third projecting member 906 and the stepped interface 908 may contribute to the overall adaptability of the shelf system. This design may allow a single bracket model to be compatible with a wide range of refrigerated display case configurations, simplifying inventory management for retailers with diverse case fleets.

[0087] FIGS. 13 and 14 illustrate the widthwise adjustability of the shelf 200, demonstrating how the left bracket 206 and right bracket 208 can be positioned at different widths to accommodate various refrigerated display case configurations.

[0088] In FIG. 13, the shelf 200 is shown with the left bracket 206 and right bracket 208 set at their furthest inward positions showing a minimum width configuration. In this configuration, the slide channels of the brackets are fulling inserted into the main channels (channel 302, channel 304, and channel 306) and are not visible.

[0089] FIG. 14 depicts the shelf 200 with the left bracket 206 and right bracket 208 set at their furthest outward positions, demonstrating the maximum width configuration. In this view, the slide channels of both brackets are visible, extending into the main channels of the shelf. Specifically, the first slide channel 402, the second slide channel 404, and the third slide channel 406 are partially inserted into the corresponding main channels and are partly visible. Also, the fourth slide channel 412, the fifth slide channel 414, and the sixth slide channel 416 are partially inserted into the main channels and are partly visible.

[0090] The adjustability mechanism allows the mounting width to be customized to fit various upright spacings (that is, the separation distance between uprights in a case) in different refrigerated display cases.

[0091] In both configurations, the movement of the brackets may be limited by the adjacent flanges of the main panel 202. These flanges may act as stops, preventing the brackets from disengaging from the main channels while allowing for a range of width adjustments. This design may provide a secure connection between the brackets and the main panel throughout the adjustment range, ensuring stability and structural integrity of the shelf at any width setting.

[0092] The widthwise adjustability feature demonstrated in FIGS. 13 and 14 may allow a single shelf to be compatible with multiple refrigerated display case configurations, reducing inventory complexity for retailers with diverse case fleets. This adaptability may also facilitate easier replacement and reconfiguration of shelving in existing refrigerated display cases.

[0093] FIG. 15 illustrates a perspective view of a shelf system for refrigerated display cases, demonstrating the compatibility of an exemplary shelf 200 with multiple display configurations. The figure shows the shelf 200, featuring a right bracket 208, installed on four different upright and case panel combinations. For simplicity and clarity, each display configuration is represented by a panel with a pair of uprights.

[0094] From right to left, the shelf 200 is shown mounted to an upright 1510 and an upright 1511 associated with a first case panel 1500, an upright 1512 and an upright 1513 associated with a second case panel 1502, an upright 1514 and an upright 1515 associated with a third case panel 1504, and an upright 1516 and an upright 1517 associated with a fourth case panel 1506. This arrangement visually demonstrates how the single shelf design may adapt to various upright standards and case configurations commonly found in refrigerated display cases from different manufacturers.

[0095] The versatility of the shelf 200 and its bracket design allows for compatibility across these diverse case configurations without requiring multiple shelf models. This adaptability may simplify inventory management for retailers with a variety of refrigerated display case types and reduce costs associated with stocking multiple shelf designs.

[0096] To better understand how bracket 208 may be attached to different upright standards, FIGS. 16-23 show examples of the upright standards and associated attachment configurations for each of the display configurations of FIG. 15. These four configurations are associated with four different upright standards shown in FIGS. 16, 18, 20, and 22. Each upright includes an upright wall with a set of holes, and the standard determines the size and spacing of the holes, as well as the upright wall thickness. For example, as shown in FIG. 16, upright 1510 has an upright wall 1602 with a set of holes 1610. The dimensions of the holes, relative spacing, and wall thickness are all associated with an upright standard that may be consistent across a particular product line of cases produced by a manufacturer. This upright standard comprises a standard hole height 1620, a standard hole width 1622, and a standard vertical hole spacing 1624. The upright standard also comprises a standard wall thickness 1701 (see FIG. 17) corresponding to a thickness of upright wall 1602.

[0097] As shown in FIG. 18, upright 1512 has an upright wall 1802 with a set of holes 1810. The dimensions of the holes, relative spacing, and wall thickness are all associated with an upright standard that may be consistent across a particular product line of cases produced by a manufacturer. This upright standard comprises a standard hole height 1820, a standard hole width 1822, and a standard vertical hole spacing 1824. The upright standard also comprises a standard wall thickness 1901 (see FIG. 19) corresponding to a thickness of upright wall 1802.

[0098] As shown in FIG. 20, upright 1514 has an upright wall 2002 with a set of holes 2010. The dimensions of the holes, relative spacing, and wall thickness are all associated with an upright standard that may be consistent across a particular product line of cases produced by a manufacturer. This upright standard comprises a standard hole height 2020, a standard hole width 2022, and a standard vertical hole spacing 2024. The upright standard also comprises a standard wall thickness 2101 (see FIG. 21) corresponding to a thickness of upright wall 2002.

[0099] As shown in FIG. 22, upright 1516 has an upright wall 2202 with a set of holes 2210. The dimensions of the holes, relative spacing, and wall thickness are all associated with an upright standard that may be consistent across a particular product line of cases produced by a manufacturer. This upright standard comprises a standard hole height 2220, a standard hole width 2222, and a standard vertical hole spacing 2224. The upright standard also comprises a standard wall thickness 2301 (see FIG. 23) corresponding to a thickness of upright wall 2202.

[0100] The exemplary bracket design is configured to be mounted to each of the different uprights despite the variations in upright standards, including differences in hole sizes, spacing, and wall thickness. This is accomplished by a bracket geometry that makes sufficient contact with each of the different uprights to facilitate attachment and sufficient load bearing for the shelves. In particular, use of a stepped slot geometry helps ensure that the projecting members can grasp ahold of different types of uprights, and the use of a stepped interface ensures the bracket is sufficiently level and provides the necessary load bearing for the given configuration.

[0101] As seen in FIG. 17, bracket 208 may be attached to upright 1510. Specifically, first projecting member 902 and second projecting member 904 are sized to fit through a first hole 1720 and a second hole 1722 of upright 1510. That is, the heights of the projecting members (for example, height 970 of first projecting member 902) are not greater than the corresponding hole height 1620 of first hole 1720 and second hole 1722. Moreover, as shown in FIGS. 19, 21 and 23, first projecting member 902 and second projecting member 904 have heights (and relative spacings) that are suitable to fit through holes in each of upright 1512, upright 1514, and upright 1516. That is, the projecting members have suitable heights to fit through each of holes 1810, holes 2020 and holes 2210. Moreover, while not shown in the figures, it may be appreciated that each projecting member has a sufficient thickness to be inserted through each of these holes such that the thickness is no greater than any of the hole width standards for the various uprights.

[0102] Additionally, as seen in FIG. 17, slot 922 of first projecting member 902 and slot 932 of second projecting member 904 may receive portions of upright wall 1602. For example, slot 922 receives a portion 1702 of upright wall 1602. As seen in FIG. 17, upright wall thickness 1701 is narrow enough to fit into both first slot portion 950 and second slot portion 952 of first slot 922.

[0103] To facilitate load bearing and leveling, third projecting member 906 may insert into a hole 1722 of upright 1510. Moreover, a portion 1706 of upright wall 1602 may contact lower surface 1212 of projecting member 906 and first vertical surface 1202 of the stepped interface.

[0104] In some cases, the upright wall thickness for a given standard may be too great to fit through both slot portions. For example, for the upright standard of upright 1512 shown in FIGS. 18-19, the upright wall thickness 1901 is greater than the width of second slot portion 952. In this case, the upright wall thickness 1901 may be accommodated by first slot portion 950, which is sufficiently wide, thereby allowing first projecting member 902 to grasp ahold of portion 1902 of upright wall 1802.

[0105] The stepped interface may accommodate the particular upright standard even as upright wall 1802 may not be inserted through to the full depth of slot 922. In particular, second horizontal surface 1208 and third vertical surface 1210 of the stepped interface may contact portion 1906 of upright wall 1802.

[0106] In the configuration shown in FIG. 21, the upright wall may insert through the full depth of the slots. For example, in FIG. 21, a portion 2102 of upright wall 2002 may insert through both first slot portion 950 and second slot portion 952. That is, upright wall thickness 2101 is narrow enough to fit into second slot portion 952. As also shown in FIG. 21, lower surface 1212 and first vertical surface 1202 engage a portion 2106 of upright wall 2002.

[0107] In the configuration shown in FIG. 23, upright wall 2202 may insert through first slot portion 950 and some of, but not necessarily all of, second slot portion 952. For example, a portion 2302 of upright wall 2202 inserts into first slot portion 950 and some of second slot portion 952. However, there may be a small gap 2330 between the top of portion 2302 and the innermost surface 1116 (see FIG. 11) of slot 922. This gap is created by the contact between a portion 2306 of upright wall 2202 and the stepped interface beneath projecting member 906. Specifically, first horizonal surface 1204 and second vertical surface 1206 contact portion 2306, which displaces the bracket vertically by a small distance equivalent to the small gap 2330.

[0108] As described above, the bracket design incorporates a first projecting member with a slot having distinct first and second portions with different widths, as shown in FIGS. 9-11. The first slot portion 950 may have a first width 956 that accommodates thicker upright walls, while the second slot portion 952 may have a second width 957 that is narrower and designed for thinner upright walls. The bracket may also include a second projecting member 906 with multiple engaging surfaces provided by the stepped interface 908, as illustrated in FIG. 12. The stepped interface may include various surfaces such as lower surface 1212, first vertical step surface 1202, first horizontal step surface 1204, second vertical step surface 1206, second horizontal step surface 1208, and third vertical step surface 1210, which may serve as different engaging surfaces depending on the upright configuration.

[0109] The bracket may be sized and configured to mount onto different uprights with varying hole configurations and wall thicknesses. As demonstrated in FIGS. 16-23, the same bracket design may accommodate uprights 1510, 1512, 1514, and 1516, each having different hole heights, widths, vertical spacings, and wall thicknesses. The first portion of the slot and one engaging surface of the second projecting member may engage with a first upright having a first hole configuration and wall thickness, while the second portion of the slot and a different engaging surface may engage with a second upright having different specifications. This versatility may allow a single bracket design to function across multiple upright standards without requiring separate bracket models for each configuration.

[0110] The principles described herein may extend to other bracket designs beyond the specific embodiment illustrated. For example, FIGS. 28-46C, discussed in further detail below, illustrate embodiments of brackets with modified geometries to accommodate different bracket/shelf orientations, such as a single angular position, or three or more angular positions. In such embodiments a similar stepped slot geometry may be used to accommodate different upright standards, including different upright thicknesses. Furthermore, as discussed below, some brackets may include four projecting members, including three projecting members with slotted geometries and a fourth projecting member having a stepped interface. In these cases, the stepped interfaces may include multiple different engaging surfaces for interfacing with different upright standards.

[0111] FIGS. 24-27 depict schematic top views of shelf 200 connected to each of the different upright configurations. As seen in FIG. 24, bracket 206 and bracket 208 may be placed in their outermost positions such that the brackets are disposed against the flanges of main panel 202 in order for the brackets to insert through holes in upright 1510 and in a corresponding upright 1511. This defines a maximum width 2402 between the brackets, which corresponds to a standard for the present upright configuration. Moreover, because bracket 206 and bracket 208 are in their outermost positions, width 2402 may be similar to the width of main panel 202 in this configuration.

[0112] In FIG. 25, bracket 206 and bracket 208 may be moved inwards relative to the flanges of main panel 202, by distances of 2502 and 2504, respectively. At this adjusted width 2502 (which is less than width 2402), bracket 206 and bracket 208 may be inserted into corresponding holes of upright 1512 and upright 1513.

[0113] In FIG. 26, bracket 206 and bracket 208 may also be placed at their outmost positions to accommodate upright 1514 and upright 1515. In FIG. 27, bracket 206 and bracket 208 may be positioned inwards of the flanges of main panel 202 by distance 2703 and distance 2704, respectively. This allows bracket 206 and bracket 208 to be inserted into corresponding holes of upright 1516 and upright 1517.

[0114] Bracket 206 and bracket 208 may be separated by a width 2702 in the configuration of FIG. 27. In some cases, width 2702 may be different than width 2502, in which bracket 206 and bracket 208 are also positioned inwardly. In some cases, width 2702 may be greater than width 2502 but less than width 2402 (the maximum possible width).

[0115] It may be appreciated that the width adjustment feature and bracket slot geometry work together to accommodate different upright configurations as manufacturers may use upright standards that differ not only with respect to hole size, spacing, and wall thickness, but the display cases may differ in the width (separation distance) between uprights for engaging the left and right brackets respectively. Using the exemplary system shelf 200 may be installed into cases using a range of different upright configurations.

[0116] The components of the shelf system may be constructed from various materials, selected based on factors such as durability, cost-effectiveness, and suitability for refrigerated environments. In some aspects, metal may be used as a primary material for many of the shelf components due to its strength and ability to withstand the conditions in refrigerated display cases.

[0117] For example, the main panel, brackets, and channels may be fabricated from metals such as stainless steel, aluminum, or galvanized steel. Stainless steel may provide excellent corrosion resistance and durability, while aluminum may offer a lightweight alternative with good strength-to-weight ratio. Galvanized steel may provide a cost-effective option with good corrosion resistance.

[0118] In some cases, the metal components may be coated to enhance their properties or appearance. For instance, a powder coating may be applied to the metal surfaces. Powder coating may provide a durable, attractive finish that can resist chipping, scratching, and fading. This coating may also offer additional protection against corrosion and may be available in various colors to match different store aesthetics or branding requirements.

[0119] Other materials may also be incorporated into the shelf system design. For example, certain plastic components may be used for non-load-bearing elements or as inserts to reduce metal-on-metal contact and minimize noise. In some aspects, composite materials combining metal and plastic properties may be utilized for specific components to optimize performance characteristics.

[0120] The choice of materials and coatings may vary depending on the specific requirements of different refrigerated display case environments, such as temperature ranges, humidity levels, and exposure to cleaning agents. The material selection may also take into account factors like ease of manufacturing, assembly, and potential for recycling at the end of the product lifecycle.

[0121] A method of installing a shelf in a refrigerated display case may include several steps to accommodate different upright configurations and standards. The process may begin with adjusting the width of the shelf to match the spacing between the uprights in the case. This adjustment may be achieved by sliding the left bracket and right bracket along the main channels of the shelf.

[0122] For example, when installing the shelf into a first case with a first upright standard, the installer may measure the distance between the (corresponding holes of) uprights and adjust the brackets accordingly. The brackets may be moved inward or outward along the main channels until they align with the holes in the uprights. In some cases, the adjustments to the bracket positions are made by hand. In some cases, rather than measuring the distance between uprights, one bracket may be installed and then the position of the second bracket can be adjusted until it is aligned with the second upright.

[0123] Once the width is adjusted, the installer may align the projecting members of the brackets with the appropriate holes in the uprights. The first projecting member and second projecting member may be inserted through the holes in the upright. The installer may need to slightly angle or tilt the shelf to facilitate this insertion.

[0124] After inserting the projecting members, the installer may engage the upright wall within the slots of the projecting members. Depending on the thickness of the upright wall, it may engage with either the first slot portion, the second slot portion, or both. For thicker upright walls, the wall may only fit into the wider first slot portion, while thinner walls may insert fully into both the first and second slot portions.

[0125] The third projecting member may then be inserted into a lower hole in the upright to provide additional support and assist with leveling. The stepped interface of the bracket may come into contact with the upright wall, with different surfaces of the stepped interface engaging depending on the specific upright standard.

[0126] To complete the installation, the installer may check that the shelf is level and make any necessary adjustments. This may involve slight repositioning of the brackets or fine-tuning the engagement with the uprights.

[0127] At a later time, if the shelf needs to be installed into a second case with a different upright standard, the same method may be applied with some adjustments. The installer may first readjust the width of the shelf to match the new upright spacing in the second case. This may involve sliding the brackets to different positions along the main channels.

[0128] The installer may then align the projecting members with the holes in the new uprights, which may have different dimensions or spacing compared to the first case. The flexible design of the bracket, with its stepped slot geometry, may allow it to accommodate these differences.

[0129] When engaging the upright wall within the slots, the installer may find that the wall thickness of the second upright standard differs from the first. The slot design may accommodate this difference, with the upright wall potentially engaging different portions of the slot compared to the first installation.

[0130] The stepped interface may also interact differently with the new upright standard. Different surfaces of the stepped interface may come into contact with the upright wall, ensuring a secure fit despite the change in upright configuration.

[0131] Throughout this process, the adjustable nature of the shelf system may allow for adaptation to various upright standards without requiring different shelf models or additional components. This flexibility may enable the shelf to be easily transferred between different refrigerated display cases, potentially reducing inventory complexity and improving versatility in retail environments.

[0132] Steps of the method with respect to the embodiment of FIGS. 1-23 are discussed here. The method may involve selecting the appropriate slot portion based on the upright wall thickness and hole configuration. For uprights with thicker walls, the installer may select the first portion 950 of the slot to engage with the upright wall, as this portion may have sufficient width to accommodate the thicker material. The selection process may also involve choosing the appropriate engaging surface of the second projecting member based on the specific upright standard. Different surfaces of the stepped interface 908 may be selected depending on the upright configuration, with some installations utilizing lower surface 1212 and first vertical step surface 1202, while others may engage with first horizontal step surface 1204 and second vertical step surface 1206, or second horizontal step surface 1208 and third vertical step surface 1210.

[0133] The mounting process may involve mating the selected slot portion with the corresponding portion of the upright adjacent to the mounting hole, while simultaneously placing the selected engaging surface of the second projecting member against the appropriate portion of the upright below the first portion. This dual engagement may provide secure attachment and proper leveling of the shelf. The method may accommodate different upright standards through the selective use of different slot portions and engaging surfaces, allowing the same shelf and bracket assembly to be installed across various refrigerated display case configurations without modification.

[0134] In different embodiments, the absolute dimensions of different portions of the exemplary shelf may vary. As described, the dimensions of the slots, projecting members, and stepped interfaces may be designed to accommodate a range of upright wall thicknesses and hole configurations commonly used by various manufacturers. In some embodiments, the dimensions of the projecting members are selected to have a height and thickness are sufficiently small to fit through the various different holes associated with different upright standards. Likewise, the slot dimensions, including the height and width of both a first slot portion and a second slot portion, may be selected to ensure that the slots retain the various upright walls for the various different standards. Other relevant dimensions that may be optimized to fit with various different upright standards may include the distances between projecting members and the sizes of the surfaces of the stepped interfaces.

[0135] Still other factors that might affect dimensions of different portions include desired load-bearing capacity, material properties, manufacturing constraints, assembly considerations, thermal expansion, as well as other suitable factors.

[0136] For purposes of clarity, ranges of absolute dimensions are provided for some portions, including portions that are relevant for the universality of the shelf with different upright standards. In some embodiments, a height 970 (see FIG. 17) of projecting member 902 has a value approximately in a range of 0.4 to 0.6 inches. In some cases, height 970 has a value approximately in a range between 0.45 and 0.55 inches. Moreover, a length of a longest projecting member (corresponding approximately to distance 1032 of FIG. 10) has a value between 1.0 and 1.4 inches.

[0137] In some embodiments, dimensions of the slot portions of each slot may vary. Referring to the portions indicated in FIG. 11, in an exemplary embodiment, height 951 of first slot portion 950 has a value approximately in a range between 0.1 and 0.15 inches, while height 953 of second slot portion 952 has a value approximately in a range between 0.2 and 0.25 inches. Likewise, in an exemplary embodiment, width 956 of first slot portion 950 has a value approximately in a range between 0.175 and 0.225 inches, while width 957 of second slot portion 952 has a value approximately in a range between 0.115 and 0.155 inches.

[0138] In some embodiments, the dimensions of third projecting member 906 may vary. In some embodiments, upper surface 1230 of projecting member 906 may have a length approximately in a range between 0.3 and 0.35 inches. In some embodiments, lower surface 1212 may have a length approximately in a range between 0.18 and 0.22 inches. In some embodiments, surface 1232 has a length approximately in a range between 0.3 and 0.4 inches.

[0139] In some embodiments, the dimensions of the vertical and horizontal surfaces of the stepped interface may vary. In some embodiments, first vertical surface 1202 and second vertical surface 1206 may have lengths of approximately in a range between 0.08 and 0.10 inches. In some embodiments third vertical surface may have a length approximately in a range between 0.11 and 0.13 inches. In some embodiments, first horizontal surface 1204 may have a length approximately in a range between 0.06 and 0.07 inches, while second horizontal surface 1204 may have a length approximately in a range between 0.04 and 0.05 inches.

[0140] It may be appreciated that the exemplary dimensions described here and shown in the drawings are not intended to be limiting and in other embodiments other dimensions may be used to accommodate various different upright standards.

[0141] In some embodiments, a bracket design may be modified for different display unit types, or for particular areas of a display unit. In some cases, some shelves in a display unit may not require accommodating different angles. For example, in some freezer units, shelves may be shorter and may not be angled.

[0142] FIGS. 30 and 31 are schematic views showing an embodiment of a bracket 3000 for a shelf that does not accommodate different angular positions. In this embodiment, bracket 3000 includes a first projecting portion 3002 with a first slot 3003 and a second projecting portion 3004 with a second slot 3005. Unlike previous embodiments, these projecting members lack a second slot to accommodate different angular positions of the shelf. However, first slot 3003 and second slot 3005 may still have substantially similar geometries to the slots of the earlier embodiments. For example, first slot 3003 and second slot 3005 may have a geometry similar to slot 922 and slot 932 of a previous embodiment, including a stepped geometry.

[0143] Bracket 3000 may also include a third projecting member 3006 and stepped interface 3008 that may be substantially similar to third projecting member 906 and stepped interface 908 of an earlier embodiment.

[0144] Some embodiments of a shelf may be configured to accommodate at least three different angular positions on an upright. For example, a shelf may have a first angular position, in which the shelf is substantially horizontal, and two different angled configurations in which the shelf is not horizontal. A first angled configuration, for example, a ten degree configuration, may be used to display some items in a display unit. A second angled configuration, for example, a fifteen degree configuration, may be used to display items with an increased downward slant so that items that are stacked behind one another slide down as one of the items in a stack is removed. Of course these are only intended to be examples and other embodiments may accommodate a variety of different shelving angles.

[0145] In some embodiments, three different angular positions or configurations may be achieved using two primary projecting members with slots and a third projecting member with a stepped interface. FIGS. 28-29 show one such embodiment, in which the geometry of at least one primary projecting member and the geometry of a third projecting member closer to the bottom of the bracket are configured to accommodate a three different angular positions despite the primary projecting members only including two slots each.

[0146] FIGS. 28 and 29 are schematic views of a bracket 2800 that may be used with any of the exemplary shelves described above and shown in the Figures. Bracket 2800 may be similar in many respects to brackets already discussed, for example, bracket 208 of FIG. 8. However, bracket 2800 may also differ in at least some respects. For example, as seen in FIG. 28, a rearward end 2802 of bracket 2800 may include a curved portion 2810 with a first segment 2812 extending away in a substantially perpendicular direction from a main bracket portion 2804 (and in a direction away from slide channel members 2806) and with a second segment 2814 extending substantially perpendicularly from first segment 2812 (and in a direction that is substantially parallel with main bracket portion 2804). Using this curved geometry, main bracket portion 2804 may be inset from the location where the bracket inserts into the upright. The amount of inset may be determined by the length of first segment 2812 and may be adjusted in various embodiments to accommodate desired inset distances. Moreover, in some cases, the use of a curved portion 2810 may help improve the structural integrity of bracket 2800 under vertical loading applied by a shelf.

[0147] FIG. 29 shows a schematic enlarged view of rearward end 2802 of bracket 2800. As seen in FIG. 28, bracket 2800 includes two primary projecting members, a first projecting member 2902 and a second projecting member 2904, which are designed to engage with the upright. Bracket 2800 also includes a third projecting member 2906, which is discussed in further detail below.

[0148] Each of the projecting member 2902 and the projecting member 2904 incorporates two slots. On the first projecting member 2902, there is slot 2920 and slot 2922, while on the second projecting member 2904, there is slot 2930 and slot 2932.

[0149] Slot 2922 and slot 2932, which are positioned closer to the rearward end 2802, are oriented in a more vertical alignment. In particular, slot 2922 and slot 2932 may be oriented in a direction that is generally parallel with the edge of rearward end 2802. Slot 2920 and slot 2930, located further from the rearward end 2802, are rotated at an angle relative to slot 2922 and slot 2932 and to the rearward end 2802. Moreover, slot 2920 and slot 2930 are oriented at an angle with respect to the orientation of slot 2922 and slot 2932.

[0150] The positioning and orientation of these slots serve different purposes in shelf installation. Slot 2922 and slot 2932, being closer to the rearward end 2802 and more vertically aligned, may be used to attach the shelf in a generally horizontal configuration. That is, in a configuration in which a main panel of the shelf is generally horizontal. This arrangement may provide a stable, level surface for displaying products in the refrigerated case.

[0151] On the other hand, slot 2920 and slot 2930, which are angled and positioned further from the rearward end 2802, may allow for the installation of the shelf at an inclined orientation. This angled configuration may be useful in certain display scenarios, and in some cases may be used to improve product visibility.

[0152] The dual-slot design on each projecting member may provide flexibility in shelf installation, allowing for both horizontal and angled orientations to accommodate various merchandising needs. This versatility may enable retailers to customize their product displays within the same refrigerated case, potentially enhancing visual appeal and accessibility of items for customers.

[0153] The step-like geometries of these slots (for example, of slot 2920, slot 2922, slot 2930 and slot 2932) may be substantially similar to the geometries of slots in previous embodiments, for example, the geometries of slot 920, slot 922, slot 930, and slot 932 which are discussed above and shown, for example, in FIGS. 9-11.

[0154] By contrast with earlier embodiments, first projecting member 2902 may include a projecting portion 2950, as shown in FIG. 29. Projecting portion 2950 may extend from a rearward-most portion of first projecting member 2902 and may extend outward such that an upper most portion of projecting portion 2950 is at a substantially similar vertical height with bracket upper edge 2840, as indicated using dashed line 2980 in FIG. 29.

[0155] In some cases, the extension and orientation of projecting portion 2950 provides support for bracket 2800 when bracket achieves a third angular position, in which the walls of the upright are not engaged in any of the slots of first projecting member 2902 and second projecting member 2904. An example is shown in FIG. 40C, which shows projecting portion 2950 engaging with a wall 4000 of an upright and preventing first projecting member 2902 from backing out of a slot 4002 while bracket 2800 is in this third angular position.

[0156] The third projecting member 2906 may be designed to insert through a hole in an upright, providing load-bearing support and facilitating leveling of the shelf. This projecting member may extend from the lower portion of the bracket and may have a shape and size optimized for engagement with various upright configurations.

[0157] In an exemplary embodiment, third projecting member 2906 includes a tab portion 2960 and a stepped interface 2962. Stepped interface 2962 includes a plurality of horizontal and vertical surfaces for interfacing with slots in an upright. This interface may accommodate different upright standards used by various refrigerated display case manufacturers. In some cases, stepped interface 2962 includes similar vertical horizontal and vertical surfaces to those of stepped interface 908, which is shown in detail in FIG. 12. That is, stepped interface 2962 may similarly include three vertical surfaces and two horizontal surfaces arranged in a step-like configuration. The stepped design of the interface 2962 may allow for fine adjustments in the positioning of the bracket relative to the upright, enabling precise leveling of the shelf.

[0158] In an exemplary embodiment, third projecting member 2906 includes a straight upper edge 2970 and a sloped lower edge 2972. Moreover, third projecting member 2906 extends from an inwardly sloped edge portion 2990 of rearward end 2802 of bracket 2800. The sloped lower edge 2972 may further form a corner portion 2973 with inwardly sloped edge portion 2990. In some embodiments, this configuration allows bracket 2800 to achieve a third angular position, which may be seen, for example, in FIG. 40C. In particular, referring to FIG. 40C, in a third angular position, third projecting member 2906 may be inserted completely through a slot in the upright, while corner portion 2973 catches on a portion of the upright. Also, in this third angular position inwardly sloped edge portion 2990 of rearward end 2802 may be flush against the upright outer side. If this portion were not inwardly sloped, rearward end 2802 would stop third projecting member 2906 from being fully inserted through a slot and prevent the bracket from achieving this third angular position.

[0159] Referring back to FIG. 29, the configuration of first projecting member 2902, second projecting member 2904 and third projecting member 2906 may be configured to interface, and secure bracket 2800 to, a variety of different upright standards. In some embodiments, first projecting member 2902, second projecting member 2904 and third projecting member 2906 may interface with the walls of an upright in a substantially similar manner as the configurations shown in FIGS. 17, 19, 21, and 23. In particular, because the geometries of the slots in first projecting member 2902 and second projecting member 2904 may be substantially similar to the geometries of the slots in, for example, first projecting member 902 and second projecting member 904 of prior embodiments, these slots may engage different upright standards in similar ways to those of first projecting member 902 and second projecting member 904. Likewise, because tab portion 2960 and stepped interface 2962 may include a similar geometry to, for example, third projecting member 906 stepped interface 908, respectively, tab portion 2960 and stepped interface 2962 may engage with different upright standards in similar ways to third projecting member 906 and stepped interface 908.

[0160] FIGS. 32-34 are schematic views of an alternative embodiment of a bracket 3200 for a shelf. Bracket 3200 may, like bracket 2800, be configured to achieve three different angular positions with respect to an upright. By contrast with bracket 2800, however, bracket 3200 uses three projecting members with slots.

[0161] As seen in FIG. 32, a bracket 3200 may include three different projecting members with slots so as to attach a shelf at three different angular configurations. These include a first projecting member 3202, a second projecting member 3204, and a third projecting member 3206. Bracket 3200 may also include an additional fourth projecting member 3208 and an associated stepped interface 3210 (see FIG. 33) that engage a slot in an upright at the bottom of bracket 3200.

[0162] As seen in FIG. 33, first projecting member 3202 and second projecting member 3204 may have substantially similar geometries to first projecting member 902 and second projecting member 904 of an earlier embodiment. Each of these projecting member includes two stepped slots. First projecting member 3202 includes first slot 3220 and second slot 3222 while second projecting member 3204 includes first slot 3230 and second slot 3232. First slot 3220 and first slot 3230 are oriented in a generally vertical manner and accommodate attaching the bracket (and corresponding shelf) in a substantially horizonal configuration. Second slot 3222 and second slot 3232 are oriented along a first angular axis 3250 and accommodate attaching the bracket at a first angled position (such as 10 degrees off of vertical, for example).

[0163] By contrast with earlier embodiments, bracket 3200 includes a third projecting member 3206 to accommodate a second angled configuration (for example, fifteen degrees off of vertical). Referring now to the enlarged view of third projecting member 3206 shown in FIG. 34, this is accomplished using a first vertical wall 3302, a first horizontal wall 3304, a second vertical wall 3306, which connects with lower edge 3310 of third projecting member 3206. These walls, collective comprising a stepped portion 3350 at the end of third projecting member 3206, are seen to extend further in a horizontal direction than both slot 3222 and slot 3232. This allows the shelf to bracket to rotate to further before the stepped portion 3350 engages the walls of the upright.

[0164] Third projecting member 3206 may also include a lower projecting portion 3320 that extends downwards from lower edge 3310. In some cases, 3320 may provide additional support against an upright and may generally be flush or directly adjacent a wall of an upright, as for example in the configuration shown in FIG. 39A, in which lower projecting portion 3320 is directly adjacent a wall portion 3902 and may help resist bracket 3200 from pulling away from the upright.

[0165] FIGS. 35-46C show schematic views of how two exemplary brackets (bracket 2800 and bracket 3200) engage and accommodate four exemplary upright standards. For the upright 3500 shown in FIG. 35, FIGS. 36A-C show how bracket 3200 engages with and fits the upright 3500 at three different angular positions while FIGS. 37A-C show how bracket 2800 engages with and fits the upright at three different angular positions. For the upright 3800 shown in FIG. 38, FIGS. 39A-C show how bracket 3200 engages with and fits the upright at three different angular positions while FIGS. 40A-C show how bracket 2800 engages with and fits the upright 3800 at three different angular positions. For the upright 4100 shown in FIG. 41, FIGS. 42A-C show how bracket 3200 engages with and fits the upright at three different angular positions while FIGS. 43A-C show how bracket 2800 engages with and fits the upright 4100 at three different angular positions. For the upright shown in FIG. 44, FIGS. 45A-C show how bracket 3200 engages with and fits the upright 4400 at three different angular positions while FIGS. 46A-C show how bracket 2800 engages with and fits the upright 4400 at three different angular positions.

[0166] To accommodate three different angular positions with each of the different upright standards, different portions of bracket 2800 may be configured to contact different uprights. As seen in FIGS. 37A, to achieve the horizontal position, bracket 2800 may receive the walls of the upright in the set of slots closest to the rearward end (that is slot 2922 and slot 2932) and the third projecting member may insert into a lower opening such that tab portion 2960 rests on the wall of the adjacent lower opening. Moreover, the walls of the upright may fit into the deeper (narrower) recesses of the slots in the first and second projecting members. To achieve a second angular position (for example, a ten degree position), bracket 2800 may receive the walls of the upright in the set of slots of the first and second projecting members which are further from the rearward end (that is, slot 2920 and slot 2930), as seen in FIG. 37B. In this configuration, the tab portion 2960 of the third projecting member may insert through a lower slot and may rest on the wall of the adjacent slot in an angled orientation. To achieve a third angular position (for example, fifteen degrees), bracket 2800 may engage a portion of the upright above one of the slots using the upwardly projecting portion of the first projecting member, as seen in FIG. 37C. In this configuration, the second projecting member may be inserted through an adjacent slot but may not engage with the wall of the upright in a manner that would provide support, and instead may simply sit within that slot. Moreover, the third projecting member, including the tab portion 2960 and the stepped interface 2962, may insert completely through a lower slot of the upright until the inward sloping portion of the rearward end is flush with an outer side of the upright.

[0167] FIGS. 40A-40C illustrate three angular positions for bracket 2800 with a different upright standard. As before, the bracket achieves the different angular positions by engaging either the closest set of slots of the projecting members (FIG. 40A), the further set of slots of the projecting members (FIG. 40B) or the upwardly projecting portion of the first projecting member (FIG. 40C). However, to accommodate a different wall thickness, the walls of the upright are received only in the lower (wider) portions of the slots (as in FIGS. 40A and 40B).

[0168] To accommodate three different angular positions with each of the different upright standards, different portions of bracket 3200 may be configured to contact different uprights. As seen in FIGS. 36A, to achieve the horizontal position, bracket 3200 may receive the walls of the upright in the set of slots of the first and second projecting member that are closest to the rearward end and the fourth projecting member may insert into a lower slot such that tab portion rests on the wall of the adjacent lower slot. Moreover, the walls of the upright may fit into the deeper (narrower) recesses of the slots in the first and second projecting members. To achieve a second angular position (for example, a ten degree position), bracket 3200 may receive the walls of the upright in the set of slots of the first and second projecting members which are further from the rearward end, as seen in FIG. 36B. In this configuration, the tab of the third projecting member may insert through a lower slot and may rest on the wall of the adjacent slot in an angled orientation. To achieve a third angular position (for example, fifteen degrees), a portion of the third projecting member may engage the wall of upright, as in FIG. 36C. Specifically, the second vertical wall 3306 may engage the upright.

[0169] In this configuration, both the first and second projecting members may be disposed outside of adjacent slots in the upright and may not provide support. In some cases, as seen in FIG. 36C, an outside of the second projecting member may rest against a wall of the upright.

[0170] FIGS. 39A-39C illustrate three angular positions for bracket 2800 with a different upright standard. As before, the bracket achieves the different angular positions by engaging either the closest set of slots of the projecting members (FIG. 39A), the further set of slots of the projecting members (FIG. 39B) or providing contact with the third projecting member (FIG. 39C). However, to accommodate a different wall thickness, the third projecting member contacts the upright at the first vertical wall 3302, rather than the second vertical wall 3306, which is inset from the first vertical wall 3302. The horizontal wall 3304 may also make contact with the upright to provide support.

[0171] For each of the exemplary processes described above including multiple steps, it may be understood that in other embodiments some steps may be omitted and/or reordered. In some other embodiments, additional steps could also be possible.

[0172] While various embodiments of the invention have been described, the description is intended to be exemplary, rather than limiting, and it will be apparent to those of ordinary skill in the art that many more embodiments and implementations are possible that are within the scope of the invention. Accordingly, the invention is not to be restricted except in light of the attached claims and their equivalents. Also, various modifications and changes may be made within the scope of the attached claims.
