FIELD OF THE DISCLOSURE
This disclosure relates to gravity feed shelving, and more specifically, to a shelf divider that permits ready removal for cleaning or replacement of an underlying sliding sheet material.
BACKGROUND OF THE DISCLOSURE
Gravity feed shelving is used in many applications, including for food containers, such as in grocery and convenience stores. For example, bottles of milk, cans of soda, juice boxes, and other like items are transported, in a first in-first out format, along angled, gravity feed shelf systems. One such gravity flow shelving system is typified by U.S. Pat. No. 5,607,068, as owned by the assignee of the present disclosure. Some applications for such gravity flow shelving include indexable and adjustable positioning structure, i.e. so as to allow the shelf lane dividers to be adjusted in their position, to accommodate larger or smaller product sizes, among the multiple flow lanes of a given gravity shelf unit. Such indexable and adjustable shelf assemblies are typified by U.S. Pat. Nos. 6,047,647 and 6,332,547, both as owned by the assignee of the present disclosure.
Many different attempts have been made to create shelf divider members that extend from the front to the rear of a gravity feed shelf and which can be easily adjusted. However, the known adjustable shelf divider members prevent the easy removal of any so-called PST sheet (plastic slide track sheet) which is used to better promote gravity feeding of certain sizes and shapes of food or beverage containers. Thus, when there has been product spillage for example, i.e. milk carton leaks, onto the PST sheet, is difficult to remove the sheet without removing at least the rear, if not the entirety, of the individual shelf divider members.
Thus, there is a need for a shelf divider which is sufficiently rigid to maintain the proper gravity feed flow lanes in a gravity feed shelf system, is readily adjustable from one position to another, so as to increase or decrease the width of a given flow lane, and which will allow the ready removal of the PST sheet for cleaning or replacement.
SUMMARY OF THE DISCLOSURE
The present disclosure concerns an adjustable shelf divider adapted to be readily adjustably connected to both the front and rear ends of a gravity feed shelf, and having downwardly extending gusset members to help provide flow lane separation. Further, the shelf divider is adapted to permit ready removal of the underlying PST sheet without removal of the shelf divider member itself. The shelf divider is formed as a generally elongated L-shaped wire member. It has a low-lying front end connector clip having forwardly-extending clip projections to be selectively positioned in a desired lateral location along the gravity feed shelf's front cross bar. The shelf divider also includes an elevated rear end connection clip with rearwardly-extending clip projections to be selectively positioned in the desired lateral location along a rear cross bar of the shelf. Further, by manipulating the rear connector clip projections to be inserted in either an upper or lower position, the lowermost point of the downwardly-extending gusset members can be caused to engage, or be elevated from the underlying PST sheet. Alternatively, where no PST sheet is present, and with use of a modified rear cross bar with multiple levels of slotted openings, the gusset members can be caused to extend down through and between the wire slides forming the gravity feed shelf surface, to assist in lane separation.

DETAILED DESCRIPTION OF THE DISCLOSURE
Having reference to the drawings, where like reference numbers comprise like elements, there is shown in FIG. 1a gravity feed shelf unit, generally denoted by reference numeral 10. Shelf unit 10 includes respective side support members 12a, 12b, each formed of metallic rod stock in a generally rectangular closed loop and each carrying along its lower end a stiffening angle iron member 14 having hangar slots 16 formed transversely across shelf unit 10. The hangar slots 16 are used to adjustably position the shelf unit 10 in a well known fashion relative to the associated shelf supports (not shown). Between the respective side support members 12a, 12b are formed a series of transverse support rods 18. The transverse support rods 18 include a front support rod 20 and a rear support rod 22. Additionally, so as to provide extra support, secondary stiffener supports 19 are formed as wire sections and welded to the underneath side of certain of the respective transverse rods 18 (see FIG. 1a). An upper front support rod 24 is also formed between the front ends of side members 12a, 12b, while an upper rear support rod 26 is formed at the rear end between side members 12a, 12b. Further, a slotted crossbar 28 is formed between the upper reaches of the rear portions of side members 12a, 12b. Crossbar 28 is used to provide support between the respective side members 12a, 12b, as well as to provide lateral adjustment, in the form of slotted openings 30, as used to permit adjustment of certain shelf divider bars, as explained later herein. A plurality of shelf slide surface members, shown as laterally spaced, front-to-rear extending wire slide members 32, are formed to extend along the entire length of the shelf unit 10 as fixed to and supported by the respective front, rear and other support rods 18, 20 and 22.
As seen in FIG. 1, a food or beverage container, such as a square milk carton, a round can of soda, or other shaped container, can be gravity fed, on a first-in first-out basis, from the rear end (i.e. left end in FIG. 1a) to the front end (i.e. right end in FIG. 1a) of gravity feed shelf unit 10, across the wire slide surface members 32. In some situations, it has been found that a plastic slide track (PST) material, such as a plastic slide sheet member 34 (see FIGS. 16, 6 and 3a), can be used to promote better gravity-feed sliding action along the rear-to-front dimension of gravity feed shelf unit 10. Such a PST member 34 can be formed of, for example, a ridge-configured sheet made of polystyrene with injected silicone material.
Referring to FIGS. 1a, 1b, and 6, there is seen a plurality of adjustable shelf divider members, each generally denoted by reference numeral 36. Each shelf divider member 36 comprises a generally elongate L-shaped support bar 38, preferably formed as a paint-coated steel rod member. Each bar 38 comprises an upper elongate horizontal section 40 (i.e. oriented generally parallel to the shelf unit 10) and a downwardly bent relatively short vertical section 42 (i.e. depending generally perpendicular to the upper elongate horizontal section 40) to be located along the front of the shelf unit 10. A divider wire 44, as formed into a pair of downwardly-extending generally V-shaped divider gussets 46, is preferably attached, such as by welding, to the lower side of the horizontal upper section 40. The lower points 48 of the respective generally V-shaped divider gussets 46 extend down towards, but do not always contact (at least in FIG. 3a) the upper surface 35 of PST sheet 34 as carried by the wire slide members 32. In other situations, such points 48 can touch PST sheet 34 (see FIG. 3b).
As best seen in FIG. 7, the lower end of the short vertical section 42 of shelf divider member 36 has a generally U-shaped connector clip 50. Each connector clip 50 extends outwardly from the lower front end of each shelf divider member 36 and is adapted to clip onto the lower front support rod 20 at a desired lateral position between selected respective wire slide surface members 32. The connector clip 50 grips and clips to the rod 20 generally under spring bias within support bar 38, and permits adjustable lateral positioning of the front end of the shelf divider member 36 relative to the shelf unit 10, so as to help form a flow lane thereon.
Similarly, formed so as to extend rearwardly of the rearmost (left end of FIG. 1a) end of the upper section 40 of L-shaped support bar 38 is a generally “H-shaped” rear connector clip 52. More specifically, rear connector clip 52 includes two pairs of clip projections 54, each of which pair can be placed into a pair of desired slotted openings 30 formed along slotted rear crossbar 28. It will be understood that, if the lower pair of clip projections 54 are placed into the slotted openings 30, such that the upper two clip projections 54 extend above and along the top surface 56 of slotted crossbar 28, then the lower points 48 of generally V-shaped divider gussets 46 will normally not engage the top surface 35 of plastic slide track sheet 34 (see FIGS. 1a, 1b, 3a and 4a). On the other hand (see FIGS. 3b and 4b), if instead the upper pair of clip projections 54 are inserted into the slotted openings 30 of crossbar 28, such that the lower pair of clip projections 54 extend under and along the lower surface 58 of crossbar 28, then the lower points 48 of the generally V-shaped divider gussets 46 will normally contact, i.e. be engaged into, the top surface 35 of plastic slide track sheet 34. It will be noted that the preferred form of rear connector clip 52 is shown in FIG. 5, where the clip is preferably formed as a flat stamped, generally “H” pattern member, with the clip projections 54 each bent outwardly, and that unit is then welded onto the rear end of the respective support bar 38. An alternative form of rear connector clip 52 is shown in FIG. 6, where respective generally U-shaped clips are welded to each end of a metal crossbar, which welded-up clip unit is then welded onto the rear end of the support bar 38.
Further yet, in one embodiment made in accordance with the present disclosure (see FIG. 8), no PST sheet 34 is used, and a modified slotted rear crossbar 60 is used (instead of crossbar 28) as having two vertically separated, and horizontally-aligned, rows of slotted openings 62, to, in essence, allow three vertical levels of potential engagement positions for the rear clip 52. For example (see FIG. 8), if the upper pair of clip projections 54 is inserted into the lower row of slotted openings 62 (see FIG. 8), that then causes the lower points 48 of generally V-shaped divider gussets 46 to reside even lower, that is, to extend down between and reside below the respective wire slide members 32 (see phantom location of such lower points 48 as depicted in FIG. 3b). In that case, the downwardly extending generally V-shaped divider gussets 46 are better stabilized, by being able to contact and be supported by the respective wire surface slide members 32 between which they extend. This is particularly helpful when relatively tall containers, or so-called reverse cone shaped products (such as certain yogurt containers), are the products being gravity fed through the various flow lanes of the gravity feed shelf unit 10.
Now, turning to FIGS. 1b, 3a, 3b, and 6, it is seen that the rear edge 64 of the plastic slide track sheet 34, and hence the sheet 34 itself, can be readily removed, i.e. grabbed and lifted out, from the rear of shelf unit 10 (see rear edge 64 of sheet 34 being removed, in phantom, in the direction of the arrow in FIG. 3b). As such, removal of the plastic slide track sheet can be accomplished without any need for disengaging one or both ends, or otherwise removing completely, the various shelf divider members 36 to free up the sheet 34.
This is a substantial advantage in that the end user of the gravity feed shelf unit 10, when formed to include the shelf divider members 36 of the present disclosure, is able to quickly remove, clean, replace, and reinstall the plastic slide track sheets 34 (assuming, of course, that all product is first removed from shelf unit 10) without any need to reconfigure, or otherwise unhook or remove, any of the shelf divider members 36 or any portions thereof. This presents a significant savings in both time and labor over prior shelf dividers for gravity feed shelf systems.
Based on the foregoing, one of ordinary skill in the art will readily understand that the teachings of this disclosure can be employed to create a shelf divider to assist in unencumbered sliding track sheet removal for gravity feed shelving systems.
