Tray divider panel attachment for wire-sided trays

Abstract

A clip-on side panel for attachment to a wire side guide of a product display tray. Many product display trays have width-adjustable wire guides at each side to confine the products into a front-to-back column. Many soft products, however, such as bagged products, can project through the open areas of the wire guides and cause problems. Trays are available with flat metal sides, but at a greater cost. The side panel attachment is an inexpensive, extruded, flat panel with an integral clip extending lengthwise at the level of the horizontal guide wire. The panel has openings at the base for engaging vertical end portions of the guide wire. The panels can be very quickly and easily installed on the guide wires of a tray for more effective confinement of soft products. The panels can just as easily be removed for other products, such as boxes, to provide greater visibility.

DETAILED DESCRIPTION OF THE INVENTION

(10) Referring to the drawings, and initially to FIGS. 1, 4, 6 and 7 thereof, the reference numeral 20 designates generally a wire-sided product display tray which, for convenience, is shown with a product confinement guide on only one side, it being understood that a typical functional tray will have product guides on both sides to confine the displayed products to an orderly, front-to-back column. The tray 20 can be of the general type shown in the before-mentioned U.S. Pat. No. 6,866,155 and includes a base comprised of a plurality (typically 4) of longitudinally extending wires 21 mounted on front and back molded plastic base members 22, of which only the front base member is visible in the drawings. The base wires 21 typically are welded to front and back transverse wires (not shown) to form a rigid, rectangular base structure. The transverse wires extend underneath the base wires 21 and are snap-in assembled to the base members 22 such that the wires 21 and base members 22 form a more or less permanent assembly.

(11) Typically, the disclosed trays are provided with a spring-urged pusher device 28, which is mounted on the longitudinal base wires 21 and constantly urges the displayed products toward the front of the tray.

(12) The tray 20 has a wire side 23 which is comprised of front and back vertical wires 24, 25 connected at their tops by an elongated, horizontally extending side wire 26. The vertical wires 24, 25 are joined at their lower ends with horizontal, inwardly extending mounting wires 27, which are frictionally received in transversely extending recesses (not shown) provided in the base members 22. The mounting wires 27 typically are approximately as long as the base members and, when fully inserted therein, as shown in the drawings, result in a tray of minimum width. For wider products, the mounting wires 27 are pulled outward on one or both sides of the tray as necessary to accommodate a wider product.

(13) As will be appreciated, the wire sides 23 are light weight, inexpensive and fully functional for the display of products in containers which are formed of a rigid material or are otherwise able to retain their shape. For some products, however, such as products sold in bags, for example, the extensive open area of the wire sides can allow portions of the soft packages to project laterally outward of the confining planes defined by the vertical wires 24, 25 and the elongated horizontal wires 26. In such cases, packages in one tray may engage with packages in an adjacent tray, or with the hardware of an adjacent tray, causing problems. The present invention enables those issues to be quickly resolved by the attachment of a flat side panel 29 to the wire side 23 to provide for physical confinement of soft packaging. As reflected in FIGS. 1. 4, 6 and 7 one embodiment of the side panel 29, forming a low side wall, is formed of an elongated panel 30 of a length to extend horizontally a distance to fit between the front and back vertical wires 24, 25. The panel 30 is also of a height to extend vertically in a space between the elongated horizontal side wire 26 and a level slightly above the base wires 21.

(14) At its upper edge, the side panel 29 is formed with a wire-gripping section 31 of arcuate, outwardly convex contour, which extends the full length of the side panel and is configured to receive one side of the horizontal side wire 26. A portion 32 of the side panel extends vertically upward for a short distance (e.g., 0.25 inch) above the wire-gripping section 31 and connects with a wire-clip section 33 which extends downwardly on the inside of the panel extension 32. At its lower end, the wire-clip section joins with an arcuate wire-gripping portion 34 of inwardly convex contour, positioned opposite the wire-gripping section 31. The lower edge of the wire-gripping portion 34 is provided with a short guide flange 35, which extends downward and inward. As will be more fully described, the side wall 29 can be quickly attached to the horizontal side wire 26 by positioning the panel 30 between the vertical wires 24, 25 and on the outside of the wire 26, such that the inside surface of the panel is in contact with the side wire 26 and the wire gripping elements 31, 31 lie above the wire 26. By pulling downward on the side wall 29, the guide flange 35 opens the wire-clip section 33 enabling the horizontal wire 26 to be resiliently gripped along its full length between the arcuate gripping elements 31, 33. Desirably, the gripping elements are symmetrically contoured so that the plane of the panel 30 is close to the centerline of the horizontal wire 26, when the side wall 29 in mounted on the wire.

(15) In accordance with an aspect of the invention, the side wall 29 is provided with means spaced below the wire-gripping elements 31, 34 to engage the front and back vertical wires 24, 25 and/or the mounting wires 27 in order to stabilize the side wall 29 in a vertical orientation. As reflected particularly in FIGS. 1, 4, 6 and 7, the extruded side wall includes an integral panel base 36 along the lower edge of the panel 30 which projects forward beyond the front vertical wire 24 and rearward beyond the back vertical wire 25. In the illustrated embodiment, the panel base has a first portion 37, which extends inward and downward from the lower edge of the panel 30, and a second portion 38, which extends downward and outward from the lower edge of the first portion 37. Preferably, a short section 39 extends downward from the lower edge of the second portion 38.

(16) In a representative but non-limiting embodiment of the invention the side wall 29 may be extruded of material such as PVC. It may have an overall height of about 3.14 inches and a thickness of about 0.055 inch. The lower or second portion 38 of the panel base may be disposed an angle of about 60 to the vertical, and about 55 with respect to the upper or first portion 37 of the panel base.

(17) At the projecting front and back end extremities of the panel base 36, openings 40, 41 are provided for the reception of the horizontal mounting wires 27 and the front and back vertical wires 24, 25. In the extruded production of the side wall 29, as it exits from the extruder and is cooled and solidified, the openings 40, 41 are formed by suitable punch operation, preferably at right angles to the plane of the side wall 29. When installing the side wall 29 on a wire side 23, the mounting wires 27 at the front and back are first inserted into the openings 40, 41, in an outside-in direction. The insertion continues until the vertical wires 24, 25 are in the openings and the wire gripping elements 31, 34 are above the horizontal side wire 26. At this point the top of the side wall 29 is pressed downward, to force the gripping elements 31, 34 over the wire 26, firmly attaching the side wall 29 to the wire. As reflected in FIGS. 1 and 4, the lower or second portion 38 of the panel base 36 engages the two vertical wires 24, 25 near the bottoms thereof to orient and stabilize the side wall 29 is a vertical position, substantially in a plane defined by the horizontal and vertical wires 26, 24, 25 of the wire side 23.

(18) With reference to FIGS. 2, 3, 5, 8 and 8, there is shown a second embodiment of the invention, in which the side wall extends upward a distance above the horizontal side wire 26 on which it is mounted. In the illustrated second embodiment, the tray is identical to that shown in FIGS. 1, 4, 6 and 7, and the elements thereof are identified with the same reference numerals as used in connection with the first embodiment. Likewise, many of the elements of the side wall of the second embodiment are the same as in the first embodiment, and such common elements are identified with reference numerals similar to those used in connection with the first embodiment but with 100 added to corresponding reference numerals.

(19) Referring now to FIG. 2, the flat panel side wall 129 corresponds in all respects to the side wall 29 of FIG. 1, except that the side wall 129 has an upper panel 130a which extends upward an additional approximately 3 inches, providing an overall height of the side wall 129 of about 6 inches. As shown in FIG. 9, the upper panel 130a is in the same plane as the lower plane. The upper and lower panels 130 and 130a are integrally joined by an arcuate wire gripping section 131 which is positioned and configured to engage one side of the horizontal wire 26. The opposite side of the horizontal wire 26 is engaged by the wire gripping portion 134 of a wire clip section 133 that is joined with the upper panel 130a at a distance (e.g., 0.25 inch) above the wire gripping section 131 and extends downward along the inside of the upper panel 130a. The wire gripping portion 134 is positioned opposite the wire gripping section 131 and is of similar configuration. A guide flange 135 extends downward and inward from the lower edge of the wire-gripping portion 134 to assist in guiding the wire 26 into the clip. Preferably, the wire clip section 133 is somewhat thinner than the panels 130, 130a and is easily deflected when installing the side wall 139 onto a side wire 26.

(20) Attachment of the high side wall 129 to the side wire 26 is performed in the same manner as for the low side wall 29. The wire side 23 is detached from its tray, allowing the mounting wires 27 to be inserted into the panel base openings 140, 141. Before inserting the mounting wires 27, the side wall panels 130, 130a are positioned on the outer side of the horizontal wire 26 and between the vertical wires 24, 25. Thus, as the mounting wires 27, and then the vertical wires 24, 25, enter the openings, the horizontal wire 26 can be aligned with the space between the wire gripping elements 131, 134 and can be pressed into engagement therewith. To remove the side wall panel 129 and restore the tray to its original form, the wire side is first detached from the front and back tray bases 22. The wire gripping elements 131, 134, are spread apart at one end to enable the wire 26 to be removed from the clip, and the wire sections 24, 25 and 27 are withdrawn from the panel base openings 140, 141. The mounting elements 27 are then reinserted in the base members 22, restoring the tray to its original configuration.

(21) The invention provides a uniquely simplified, convenient and inexpensive way to convert a wire-sided tray to a panel-sided tray where necessary or desirable to accommodate soft packages that may not be well confined by wire-sided trays. The conversion is accomplished by the clip-on attachment of an extruded plastic panel to the elongated horizontal wire of an existing wire-sided tray, in conjunction with means for retaining the plastic panel in a vertical orientation. In the illustrated form of the invention the panel is retained in a vertical orientation by engagement of lower portions of the panel with existing elements of the wire side guide. Just as easily as a wire-sided tray may be converted to a panel-sided tray, the tray may be re-converted to wire-only confinement where such might be preferred. The entire process of conversion and/or re-conversion is quickly accomplished, requires no tools nor any special skills.

(22) It should be understood, however, that the embodiments of the invention herein illustrated and described are intended to be representative of the invention and not in any way in limitation thereof, as certain changes may be made therein without departing from the clear teachings of the disclosure. Accordingly, reference should be made to the appended claims in order to determine the full scope of the invention.
