DISPLAY SHELF WITH ADJUSTABLE DIVIDER WALLS
A divider wall for use with a gravity-fed shelf assembly includes an elongate wall portion and a first front leg extending from a first end of the wall portion. The first front leg has a body portion and an engagement protrusion extending from the body portion. The divider wall further includes a rear leg extending from a second end of the wall portion. The first front leg and the rear leg are each adapted to be received into a front slot and a rear slot, respectively, of the shelf assembly. Gravity acts on the divider wall and displaces it within the front and rear slots toward a front end of the shelf assembly such that an undersurface of the shelf assembly adjacent the front slot is in contact with or immediately adjacent to the engagement protrusion to prevent the removal of the first front leg from the front slot.

This disclosure relates generally to shelving systems and, more particularly, to divider walls that are removably coupled to shelf assemblies of such shelving systems.
BACKGROUND OF THE INVENTIONGravity-flow shelving systems are commonly used in retail food outlets to both store and display consumable items, such as individual-serving food containers or beverage containers. Gravity-flow shelving systems generally include one or more display shelves (also called shelf assemblies) supported by a support frame, and each such shelf assembly is inclined relative to a horizontal plane such that items stored on the shelf assembly slide towards a visible and accessible area at the front of the shelf assembly. Each shelf assembly may have a plurality of channels that are formed by divider walls disposed along the length of the shelf assembly. The width of each of the channels may correspond to the width of the containers stored on the respective channel of the shelf assembly to group the containers in a visually appealing array of rows.
However, when the shelf assemblies are initially configured, or subsequently reconfigured to store the containers described above, the channel widths must be carefully calculated for each row of containers. This process of calculating channel widths and repositioning divider walls is time consuming, especially considering the large number of shelves that are typically restocked or reconfigured each day at retail food outlets. Once the position of each of the divider walls is determined, the divider walls must be secured to the shelf assembly to prevent accidental disengagement of the divider wall from the shelf assembly during use. Typically, it is time-consuming to engage and disengage the divider walls using conventional securing mechanisms, thereby reducing the efficiency of the employees tasked with reconfiguring the channel widths.
Moreover, the divider walls are typically planar walls or rods that longitudinally extend across the length of the shelf assembly. Such elongate divider walls offer little resistance to lateral (i.e., normal to the wall or rod) loads that result from the shifting of larger containers, such as gallons of milk. As such, divider walls may laterally deform, or “bow,” resulting in the lateral shifting of containers in the longitudinal channels, creating a disorganized visual product presentation to the consumer and also potentially disrupting the flow of containers in adjacent channels. In addition, significant lateral loads may permanently deform the divider wall, requiring the repair or replacement of the damaged divider wall.
The adjustable divider wall of the present disclosure overcomes these and other shortcomings of conventional divider walls. As compared with typical divider walls, the divider wall of the present disclosure provides for the fast and accurate creation of channels for accommodating gravity-influenced inventory control of products while providing increased stiffness to resist lateral loads. Additionally, the divider wall of the present disclosure includes a gravity-driven engagement feature that prevents the divider wall from being inadvertently disengaged from the shelf assembly while allowing for the fast and easy intentional removal of the divider wall from the shelf assembly.
BRIEF SUMMARY OF THE DISCLOSUREThe divider wall of the present disclosure includes an elongate wall portion that may extend along a longitudinal axis such that the wall portion includes a first end and an oppositely-disposed second end. The wall portion may be planar, substantially planar, or partially composed of planar segments. The wall portion may be defined by a top edge that horizontally extends (relative to a plane of a shelf to which the divider wall is to be secured) between the first end and the second end, and a bottom edge may be parallel to and vertically offset from the top edge. The wall portion may be further defined by a rear edge disposed at or adjacent to the second end of the wall portion. The rear edge may be vertical (again, relative to a plane of a shelf to which the divider wall is to be secured) and may extend between the top edge and the bottom edge. The wall portion may be additionally defined by a front edge disposed at or adjacent to the first end of the wall portion. The front edge may be vertical such that the front edge is parallel to the rear edge. A front rounded edge may extend between the top edge and the front edge, and a rear rounded edge may extend between the top edge and the rear edge. The front edge and the rear edge may be separated by any suitable distance that allows the divider wall to extend from the front end of the shelf assembly to the rear end. The edges may each form a corresponding edge segment of a continuous perimeter surface that extends in a transverse direction around the perimeter of the wall portion.
The wall portion may also include a rigidifying portion that increases the bending stiffness of the wall portion. More specifically, the rigidifying portion reduces transverse deformation or bending of the wall portion when the wall portion is subjected to transverse loads. The rigidifying portion may longitudinally extend along the entire length of the wall portion, or the rigidifying portion may extend along one or more longitudinal segments of the wall portion. The rigidifying portion may include a top oblique portion that obliquely extends from the first surface of the wall portion such that the top oblique portion forms an obtuse angle with a top planar portion. The rigidifying portion may also include a bottom oblique portion that obliquely extends from the first surface of the wall portion such that the bottom oblique portion forms an obtuse angle with a bottom planar portion, wherein the bottom planar portion and the top planar portion are each bisected by a longitudinal plane. An intermediate planar portion may extend between the inwardly-disposed ends of the top oblique portion and the bottom oblique portion such that the intermediate planar portion is transversely offset from both the top planar portion and the bottom planar portion. In another embodiment, the rigidifying portion may include a single intermediate oblique portion that obliquely extends from the first surface of the wall portion such that the intermediate oblique portion forms an obtuse angle with the bottom planar portion. A top planar portion may extend from an end of the intermediate oblique portion such that the top planar portion is parallel to and transversely offset from the bottom planar portion.
The divider wall also includes a first front leg a disposed adjacent to the first end of the wall portion. The first front leg may vertically extend downwardly from the wall portion. The first front leg may be integrally formed with the wall portion, and the first front leg includes a body portion that may have a first end that is in contact with or adjacent to the bottom edge of the wall portion. The body portion may also have a second end opposite to, and spaced vertically downward from, the first end. The body portion may be defined by a vertical or substantially vertical first side edge and a second side edge that may be parallel to and offset from the first side edge. At the second end of the body portion, a bottom edge may extend from the second side edge towards the first side edge. The first end of the body portion may include a step side edge that vertically extends from the bottom edge of the wall portion. A second step bottom edge may horizontally extend from the step side edge to the second side edge. A first step bottom edge may horizontally extend from the front edge of the wall portion to the first side edge of the first front leg, and the second step bottom edge and the first step bottom edge may be horizontally aligned.
The first front leg also includes an engagement protrusion that extends from the body portion, and the engagement protrusion may extend in a horizontal direction from the first side edge at or adjacent to the second end of the body portion. The engagement protrusion may be defined by the bottom edge of the body portion and may be further defined by a front engagement edge that vertically extends from a frontward, terminal end of the bottom edge. The engagement protrusion may also be defined by a top engagement edge that horizontally extends between the front engagement edge and the first side edge such that the top engagement edge forms an undercut surface of the engagement protrusion. With the first front leg integrally formed with the wall portion, the edges defining the first front leg may each form a corresponding edge segment of the continuous perimeter surface that extends in a transverse direction around the perimeter of the first front leg.
The first front leg may not be integrally formed with the wall portion, but may instead be coupled to the wall portion. Such an embodiment of the first front leg may have a substantially planar top leg portion that is bisected by a first leg longitudinal plane. As such, the top leg portion has a first top leg surface and a second top leg surface that are each parallel to and equidistant from the first leg longitudinal plane. The first top leg surface may be coupled to a first surface of the wall portion. The top leg portion may be further defined by a vertical first side edge and a second side edge that is parallel to and offset from the first side edge. A horizontal top edge may extend between the first side edge and the second side edge at a first end of the top leg portion. A leg transition portion may extend from a second end of the top leg portion, and the leg transition portion may transversely and obliquely extend from the second top leg surface at the second end of the top leg portion. The leg transition portion may be laterally defined by the first side edge and second side edge of the top leg portion. The first front leg may additionally include a substantially planar bottom leg portion that may extend from a terminal end of the leg transition portion such that a second leg longitudinal plane that bisects the bottom leg portion may be parallel to and offset from the first leg longitudinal plane. A second bottom leg surface that is parallel to and offset from the second leg longitudinal plane may be transversely separated from the first top leg surface. The bottom leg portion includes a body portion and an engagement protrusion that are identical to the body portion and the engagement protrusion previously described. The edges defining the first front leg may each form a corresponding edge segment of a continuous perimeter surface that extends in a transverse direction around the perimeter of the first front leg.
The divider wall may also include a second front leg coupled to the first end of the wall portion. The second front leg may be a minor image of—but otherwise identical to—the first front leg. As such, the first top leg surface of the second front leg may be coupled to a second surface of the wall portion.
The divider wall may also include a rear leg that vertically extends from the wall portion adjacent the second end. The rear leg may be integrally formed with the wall portion or may be coupled to the wall portion. The rear leg may be substantially identical to the first front leg that is integrally formed with or coupled to the wall portion, with the exception being the absence of an engagement protrusion on the rear leg and a potential difference in the horizontal distance between the first side edges and the second side edges of the body portions of the first front leg and the rear leg, respectively. A second rear leg may also be included that is substantially identical to the second front leg.
The divider wall may also include an intermediate leg that is disposed between the rear leg and the first front leg and the intermediate leg may vertically extend from the wall portion. The intermediate leg may be identical to the rear leg. However, when the intermediate leg is coupled to the wall portion instead of integrally formed with the wall portion, the intermediate leg may not have a leg transition portion and may instead be planar.
Configured as described, the divider wall may be removably coupled to a shelf assembly that may be used to support and display disposable food containers, and multiple shelf assemblies that are vertically offset may be supported by a support frame. Each shelf assembly has a rectangular shape and includes a plurality of transversely-aligned rear slots at or adjacent to the rear end of the shelf assembly. The shelf assembly also includes a plurality of transversely-aligned front slots disposed at or adjacent to the front end of the shelf assembly. Each of the plurality of front and rear slots may have a uniform width and a uniform length, and each of the plurality of rear slots may be horizontally aligned with a corresponding one of the front slots. Optionally, and particularly in the case of shelf assemblies having a front-to-rear length of at least four feet or approximately four feet, a transversely-aligned intermediate row of slots is disposed between the front slots and the rear slots. The intermediate row of slots may be centered or approximately centered between the front slots and the rear slots. The shelf assembly may include an additional transversely-aligned intermediate row of slots for each foot of length in excess of four feet. For example, if the front-to-rear length of the shelf assembly is five feet or approximately five feet, the shelf assembly may include two parallel and offset intermediate rows of slots that are disposed between the front and rear slots. The shelf assembly may also include a plurality of support tracks that longitudinally extends from the front end to the rear end of the shelf assembly. A plurality of elongate rollers may be transversely disposed between and rotatably coupled to adjacent support tracks. Due to the rotatable rollers, containers disposed on the shelf assembly will (or will have a tendency to) translate towards the front end of the shelf assembly under the influence of gravity when the front end of the shelf assembly is disposed lower than the rear end of the shelf assembly. When two or more divider walls are longitudinally disposed on the shelf assembly, one or more channels may be formed between adjacent divider walls. The channels may have a transverse width that generally corresponds to the width of the container located in a particular channel to maintain the containers in uniform longitudinal rows.
To removably couple a divider wall to the shelf assembly, the first front leg is vertically aligned with a suitable front slot and the rear leg is vertically aligned with a suitable corresponding rear slot. If a transversely-aligned row of intermediate slots is disposed between the front slots and the rear slots, and the divider wall includes an intermediate leg, then the intermediate leg is vertically aligned with a corresponding intermediate slot. If more than one transversely-aligned row of intermediate slots is disposed between the front slots and the rear slots of the shelf assembly, the divider wall may include at least two longitudinally offset intermediate legs. If such longitudinally offset intermediate legs are disposed on the divider wall, each intermediate leg may be vertically aligned with a corresponding one of the slots of each of the transversely-aligned intermediate row of slots. The divider wall is then vertically displaced towards the shelf assembly such that the first front leg is received into the front slot and the rear leg is received into the rear slot (and, if applicable, each of the intermediate legs is received into a corresponding intermediate slot). The divider wall is continued to be displaced towards the shelf assembly until one or both of the first step bottom edge and the second step bottom edge contacts an upper surface of the shelf assembly adjacent the front slot, and until one or both of the first step bottom edge and the second step bottom edge contacts an upper surface of the shelf assembly adjacent the rear slot (and, if applicable, the intermediate slot or slots).
When the first front leg and the rear leg (and, if applicable, the intermediate leg or legs) are fully inserted into the front slot and the rear slot (and the intermediate slot or slots), respectively, the divider wall is released and is allowed to displace towards the front end of the shelf assembly under the influence of (or with the assistance of) gravity. Eventually, a portion of the perimeter surface that is bounded by the first side edge of the first front leg comes into contact with a forward wall that partially defines the front slot, thereby preventing further forward displacement of the divider wall within the slot. At this time, a portion of the perimeter surface that is bounded by the first side edge of the rear leg may come into contact with (or may be closely adjacent to) a forward wall that defines the rear slot, and, if appropriate, a portion of the perimeter surface that is bounded by the first side edge of each of the intermediate legs may come into contact with (or may be closely adjacent to) a forward wall that defines each of the intermediate slots. So positioned, an undersurface of the shelf assembly adjacent the front slot is in contact with or immediately adjacent to the engagement protrusion of the first front leg. More specifically, the undersurface of the shelf assembly is in contact with or immediately adjacent to the portion of the perimeter surface that is bounded by the top engagement edge of the engagement protrusion. With the undersurface in contact with or immediately adjacent to the top engagement edge of the engagement protrusion, the divider wall is prevented from upwardly displacing relative to the shelf assembly, thereby securing the divider wall to the shelf assembly.
To disengage the divider wall from the shelf assembly, the divider wall is horizontally displaced towards the rear end of the shelf assembly until the top engagement edge of the engagement protrusion is no longer in contact with or immediately adjacent to the undersurface of the shelf assembly. In this position, the divider wall may be upwardly displaced relative to the shelf assembly such that the first front leg is no longer received into the front slot and the rear leg is no longer received into the rear slot (and, if applicable, each of the intermediate legs are no longer received into the corresponding intermediate slot or slots).
In embodiments having a first front leg and a second front leg, each of the first front leg and the second front leg are aligned with a corresponding front slot as described above. A rear leg (and a second rear leg, if applicable) is aligned with a corresponding rear slot and, if applicable, one or more intermediate legs are aligned with a corresponding intermediate slot. The first front leg and the second front leg are inserted into the corresponding front slots as previously described, and under the influence of gravity, the divider wall translates towards the front end of the shelf assembly such that a portion of the perimeter surface of the first front leg that is bounded by the first side edge comes into contact with a forward wall that partially defines the first corresponding front slot and a portion of a perimeter surface of the second front leg that is bounded by the first side edge comes into contact with a forward wall that partially defines the second corresponding front slot. At this time, a portion of a perimeter surface that is bounded by the first side edge of the rear leg may come into contact with (or may be closely adjacent to) a forward wall that defines a second corresponding rear slot, and a portion of a perimeter surface that is bounded by the first side edge of the second rear leg may come into contact with (or may be closely adjacent to) a forward wall that defines a corresponding rear slot. Additionally, if appropriate, a portion of a perimeter surface that is bounded by the first side edge of each of the corresponding intermediate legs may come into contact with (or may be closely adjacent to) a forward wall that defines each of the intermediate slots.
So positioned, the undersurface of the shelf assembly adjacent the front slots is in contact with or immediately adjacent to the engagement protrusion of each of the first front leg and the second front leg. More specifically, the undersurface of the shelf assembly is in contact with or immediately adjacent to the portion of a perimeter surface that is bounded by the top engagement edge of the each of the engagement protrusions of the first front leg and the second front leg. With the undersurface in contact with or immediately adjacent to the top engagement edges of the engagement protrusions, the divider wall is prevented from upwardly displacing relative to the shelf assembly, thereby securing the divider wall to the shelf assembly. To disengage the divider wall from the shelf assembly, the engagement process is reversed.
When secured to the shelf assembly as described, the engagement protrusion prevents the accidental or inadvertent disengagement of the divider wall from the shelf assembly. In addition, the rigidifying portion that horizontally extends along the wall portion increases the stiffness of the divider wall to more effectively resist lateral loads caused by shifting containers while maintaining an ultra-thin profile. In addition, the use of both a first front leg and a second front leg increases the engagement strength between the divider wall and the shelf assembly to effectively prevent damage to or disengagement of the divider wall when relatively large containers subject the divider wall to lateral loads.

In alternative embodiments, either or both of the top engagement edge 102 and the front engagement edge 100 may be curved edges, or may be partially curved and partially linear. In other alternative embodiments, both of the top engagement edge 102 and the front engagement edge 100 may be a single curved edge that extends between the first side edge 90 and the bottom edge 98 of the body portion 24. In further alternative embodiments, either or both of the top engagement edge 102 and the front engagement edge 100 may be linear edges that are obliquely disposed relative to the first side edge 90 of the body portion 24.
When the first front leg 22 is integrally formed with the wall portion 14, the edges 90, 92, 94, 96, 97, 98, 100, and 102 defining the first front leg 22 may each form a corresponding edge segment of the continuous perimeter surface 66 that extends in a transverse or substantially transverse direction around the perimeter of the first front leg 22. As such, the first front leg 22 may be bisected by the longitudinal plane 48, as shown in

The first front leg 22a also includes an engagement protrusion 26a that extends from the second end 88a of the body portion 24a, and the engagement protrusion 26a may extend in a horizontal direction (i.e., in a direction parallel to the longitudinal axis 16) from the first side edge 90a at or adjacent to the second end 88a of the body portion 24a. The engagement protrusion 26a may be identical or substantially identical to the engagement protrusion 26 previously described. In particular, the engagement protrusion 26a may be defined by the bottom edge 98a of the body portion 24a and may be further defined by a front engagement edge 100a that vertically extends from a frontward, terminal end of the bottom edge 98a. The engagement protrusion 26a may also be defined by a top engagement edge 102a that horizontally extends between the front engagement edge 100a and the first side edge 90a such that the top engagement edge 102a forms an undercut surface of the engagement protrusion 26a, and such an undercut surface will be described in more detail below. The edges 90a, 92a, 96a, 97a, 98a, 100a, 102a, 112a, 114a, and 116a defining the first front leg 22a may each form a corresponding edge segment of a continuous perimeter surface 129a that extends in a transverse or substantially transverse direction around the perimeter of the first front leg 22a.

The spill tray 170 may be symmetrically formed about the longitudinal reference axis A such that the spill tray 170 has second side channel wall 186b, a second top channel wall 188b, and a second side wall 190b that are a mirror image of, but otherwise identical to, the first side channel wall 186a, the first top channel wall 188a, and the first side wall 190a, respectively. So configured, the transverse distance (i.e., the distance parallel to the plane of the bottom wall 172 and normal to the longitudinal reference axis A when viewed along the longitudinal reference axis A) between an inner surface of the first side wall 190a and an inner surface of the second side wall 190b may have any suitable value to accommodate the width of a shelf assembly as will be described in more detail below. For example, the transverse distance may be 26.625″. In addition, the transverse distance between the top portion of the oblique first side channel wall 186a and a top portion of the oblique second side channel wall 186b may have any suitable value to accommodate the width of shelf assembly 12 that rests on a top surface of each of the first and second top channel walls 188a, 188b.

The spill tray 170 may be made from any suitable material, such as aluminum having a thickness of 0.040″. The spill tray 170 may be first formed from a single sheet of material or may be comprised of two or more component parts that are coupled to form the spill tray 170.
In use, a spill tray 170 may be directly or indirectly coupled to the support frame 158 in any manner known in the art, and the spill tray 170 may provide support for a corresponding shelf assembly 12, as illustrated in
To secure a shelf assembly 12 in a corresponding spill tray 170, the shelf assembly is positioned such that the front end 32 of the shelf assembly 12 is disposed adjacent to the first end 174 of the spill tray 170 and the rear end 33 of the shelf assembly 12 is disposed adjacent to the second end 176 of the spill tray 170. As illustrated in
So positioned, a first shelf sidewall 204a (illustrated in
With each spill tray 170 secured to the support frame 158 such that the first end 174 of the spill tray 170 is disposed vertically lower than the second end 176 of the spill tray 170, one having ordinary skill in the art would recognize that liquid spilling or leaking from products supported on the shelf assembly 12 would flow on the top surface of the bottom wall 172 towards the first end 174 of the spill tray 170. The front lip 198 acts as a barrier that allows such spilled fluid to exit the spill tray 170 between one or both of a first gap 210a defined by the first side edge 202a of the front lip 198 and the first side channel wall 186a and a second gap 210b defined by the second side edge 202b of the front lip 198 and the second side channel wall 186b. The liquid exiting the first and/or second gap 210a, 210b under the influence of gravity may spill into a drip tray (not shown) coupled to the support frame 158. By positioning the shelf assembly 12 vertically offset from the bottom wall 172 of the spill tray 170, and by providing the first and second gaps 210a, 210b, spilled liquid may be directed away from a customer's view. In addition, the vertical offset directs spilled liquids away from the shelf assembly 12, simplifying the cleaning of spills and resulting in a more sanitary product display environment. Additionally, in conjunction with the slim-profile divider walls 10 and the first and second side walls 190a, 190b that vertically extend to act as outmost divider walls, the spill tray 170 enables maximum product facings because the entire shelf assembly 12 is received into a single spill tray 170. This configuration can lead to an additional product facing on a single shelf assembly 12, for example.
Turning again to the divider walls 10, each divider wall 10 may be removably coupled to the shelf assembly 12 by inserting the first front leg 22 into a desired front slot 30a and the rear leg 28 into a corresponding rear slot 30b. For example, when the front slot 30a is longitudinally aligned with the rear slot 30b, the rear leg 28 of the divider wall 10 may be horizontally aligned with the first front leg 22, as illustrated in
Once aligned as described, the divider wall 10 is vertically displaced towards the shelf assembly 12 such that the first front leg 22 is received into the front slot 30a and the rear leg 28 is received into the rear slot 30b (and, if appropriate, the intermediate leg 152 is received into the intermediate slot 30c), as shown in
When the first front leg 22 and the rear leg 28 (and, if appropriate, the intermediate leg 152) are fully inserted into the front slot 30a and the rear slot 30b (and the intermediate slot 30c), respectively, the divider wall 10 is released and is allowed to displace towards the front end 32 under the influence of (or with the assistance of) gravity. Eventually, a portion of the perimeter surface 66 that is bounded by the first side edge 90 of the first front leg 22 comes into contact with a forward wall 166a that partially defines the front slot 30a, thereby preventing further forward displacement of the divider wall 10 within the slot 30a. At this time, a portion of the perimeter surface 66 that is bounded by the first side edge 136 of the rear leg 28 may come into contact with (or may be closely adjacent to) a forward wall 166b that defines the rear slot 30b, and, if appropriate, a portion of the perimeter surface 66 that is bounded by the first side edge 136 of the intermediate leg 152 may come into contact with (or may be closely adjacent to) a forward wall 166c that defines the intermediate slot 30c. So positioned, as illustrated in
To disengage the divider wall 10 from the shelf assembly 12, the divider wall 10 is horizontally displaced towards the rear end 33 of the shelf assembly 12 until the top engagement edge 102 of the engagement protrusion 26 is no longer in contact with or immediately adjacent to the undersurface 34 of the shelf assembly 12, as illustrated in
In embodiments having a first front leg 22a and a second front leg 22b, as illustrated in
So positioned, the undersurface 34 of the shelf assembly 12 adjacent the front slots 30a is in contact with or immediately adjacent to the engagement protrusion 26a, 26b of each of the first front leg 22a and the second front leg 22b. More specifically, the undersurface 34 of the shelf assembly 12 is in contact with or immediately adjacent to the portion of a perimeter surface 129a, 129b that is bounded by the top engagement edge 102a, 102b of the each of the engagement protrusions 26a, 26b of the first front leg 22a and the second front leg 22b. With the undersurface 34 in contact with or immediately adjacent to the top engagement edges 102a, 102b of the engagement protrusions 26a, 26b, the divider wall 10 is prevented from upwardly displacing relative to the shelf assembly 12, thereby securing the divider wall 10 to the shelf assembly 12.
When secured to the shelf assembly 12 as described, the engagement protrusion 26, 26a, 26b prevents the accidental or inadvertent disengagement of the divider wall 10 from the shelf assembly 12. In addition, the simple disengagement and gravity-driven engagement provides for quick and efficient reconfigurations (or initial configurations) of a shelf assembly 12 to accommodate desired containers of various sizes. Moreover, the rigidifying portion 64 that horizontally extends along the wall portion 14 increases the stiffness of the divider wall 10 to more effectively resist lateral loads caused by shifting containers while maintaining an ultra-thin profile. In addition, the use of both a first front leg 22a and a second front leg 22b, particularly in conjunction with the use of an intermediate leg 152, increases the engagement strength between the divider wall 10 and the shelf assembly 12 to effectively prevent damage to or disengagement of the divider wall 10 when relatively large containers subject the divider wall to lateral loads.
The divider wall 10, including subcomponents such as the first front legs 22a, 22, for example, may be formed from a steel blank. In addition, the rigidifying portion 64 of the wall portion 14 and/or the leg transition portion 120a of the first front leg 22a (and other similarly formed transition portions) may be formed in one or more secondary bending operations. However, other materials or manufacturing process may be used to form the divider wall 10 and appropriate subcomponents, including forming all or part of the divider wall 10 of injection-molded plastic.
