## Background
BACKGROUND AND SUMMARY OF THE INVENTION
The inventions described and claimed herein relate to price channels that attach to the front edge of display shelving in retail stores. The primary application of the inventions described and claimed herein is for warehouse-type retail stores that use wood or wood composite shelving, which typically includes metal-reinforced front and rear edges.
Warehouse-type retail stores that sell items in bulk are becoming more popular. Because the bulk items typically come in large quantities, they are heavy and the store's entire stock is may be kept on display. These warehouse-type retail stores use shelving units that were originally designed to be used as storage room shelving, such as the Lozier® S-Series Storage Shelving. These storage room shelving units were not intended to be used as display shelving for consumers and, thus, were not designed to allow for easy attachment of pricing labels. Conversely, typical display shelving units at more conventional retail outlets usually have some means for attaching labels on the front edge of the shelves such as a C-shaped channel into which labels or label holders can be attached.
Because it is important to clearly display advertising, quantity information, pricing and other information directly adjacent to items for sale at retail, the warehouse-type retail stores have resorted to various methods of attaching labels to the front edge of the shelves, such as using adhesive tape, nails, and screws, which have proved unsatisfactory. Adhesive tape is troublesome for the retailers because it is messy and provides insufficient grip on the shelves. As prices or items for sale change, it becomes necessary to change and/or move the pricing labels. The adhesive tape currently used can leave residue on the shelves which is unsightly and time-consuming to remove. Furthermore, labels attached by adhesive tape often fall off of the shelves when consumers either brush up against them or remove items from the shelves. Using nails and screws is even more troublesome because it is time consuming to install and remove labels, not to mention that permanent holes are left in the shelving units when the labels are removed.
Therefore, there is a need for a label channel which can be easily attached to and removed from the leading edge of an industrial shelving unit and which does not leave residue on or otherwise damage the shelves. The label channel of the present invention provides a better method of attaching labels because it results in an improved installation time, an improved grip on the shelf when compared to adhesive, and no damage to the shelves.
The preferred embodiment of the present invention, the clip-on price channel, is designed to clip onto the leading edge of storage room shelving, which are typically made of wood-based composite material (such as particle board) and have a metal rail permanently attached to the front and rear edges. Specifically, the clip-on price channel disclosed and claimed herein has a U-shaped grip that closely conforms to the shape of the edge of the shelf (i.e., the metal rail, if present) and a label holder which is designed to hold a sign or information sheet. At the free ends of the grip, there are two inward facing fingers that are disposed in recesses on the top and bottom surfaces of the shelf. If a metal rail is used, the fingers grip the edges of the metal rail. Where a metal rail is used the upper arm of the metal rail angles toward the lower arm. The upper arm angles at its edge where the clip-on price channel finger grips. The upper arm angles into a groove on the upper surface of the wood-based shelving. The metal rail upper arm angles at the end so as to avoid any jagged edges or abutments on the surface of the shelf. This allows for easy sliding on and off of items on the shelf. The label holder is attached to the grip of the price channel by a connector that may be in the form of a flexible hinge to allows the label holder to flex up and out of the way when the price channel is attached to the shelf and products on the shelf below are removed.

The upper arm 20 of the shelf grip 2 angles 52 toward the lower arm 21 right before the upper finger 5 extends at free end 7 to conform with the angle on the metal rail.
DETAILED DESCRIPTION OF THE DRAWINGS
FIG. 1 shows a clip-on price channel 1. The clip-on price channel 1 has three sections: a shelf grip 2, a label holder 3, and a link 4 that attaches the grip 2 to the label holder 3. The channel 1 is preferably an extrusion of a clear, transparent poly vinyl chloride (PVC).
The shelf grip 2 is configured to mate with a storage room shelf 9, such as the Lozier® S-Series Storage Shelving, as shown in FIG. 2. Such shelving 9 is typically comprised of a particle board 10 (or other wood-based composite) having a metal rail 11 affixed to the front (and rear) edge. The metal rail 11 is typically U-shaped and permanently affixed to the long edges of the shelf. The rail typically has an upper section 14 and a lower section 15 extending from opposite ends of a front plate 16. The wood board 10 has a single groove 12 on the top side 13 into which the upper section 14 of metal rail 11 extends, firmly attaching the metal rail 11 to the front edge 17 of the wood board 10. A similar rail is attached to the rear edge of the board 10. The shelf 9 has a groove 44 between the edge of the upper section 14 of the metal rail 11 and the wood portion 10 of the shelf 9, as shown in FIG. 5.
As shown in FIG. 4, the shelf-grip 2 is also U-shaped, preferably closely conforms to the shape of the metal rail 11, and has a upper arm 20, a lower arm 21, and a front panel 22. The upper arm 20 is approximately perpendicular to the front panel 22 while the lower arm 21 is angled slightly towards the upper arm 20 to provide a tight connection with the shelf 9. The upper arm 20, lower arm 21 and front panel 22 correspond to the upper section 14, lower section 15 and front plate 16 of the metal rail 11. The upper section 14 and lower section 15 of the rail are generally parallel when attached to the shelf providing the shelf with parallel upper and lower surfaces at the edges of the shelf, although they may be formed with an included angle of less than 90 degrees to that the rail grips the edge of the shelf.
Similarly, when attached to the edge of the shelf, the upper section 14 and lower section 15 of the grip 2 are parallel. However, to afford the grip 2 of the channel 1 with some gripping force, the upper section 14 and lower section 15 are preferably extruded with an included angle of less than 90 degrees (between 75 and 89 degrees). The included grip angle of the upper and lower sections, 14 and 15, in FIG. 5 is about 83 degrees. However, the size of the angle will increased or decreased, depending upon the thickness and stiffness of the material used to make the channel 1.
The shelf grip 2 has two opposing fingers 5 and 6 at both free ends 7 and 8 of the upper arm 20 and the lower arm 21, respectively. When the clip-on price channel 1 is engaged with the shelf 9, the upper finger 5 fits into the groove 44 between the metal rail 11 and wood board 10 and grips against the upper end surface 18 of the upper section 14 of the metal rail 11, as shown in FIGS. 3 and 5. The lower finger 6 grips against the lower end surface 19 of the lower section 15 of the metal rail 11. The shelf grip 2 is resilient such that the fingers 5 and 6 positively engage with the end surfaces 18 and 19 of the metal rail 11 and hold the price channel 1 firmly in place.
The label holder 3 is designed to hold a sign or information sheet 23 that is much greater in size than the leading edge 17 of the shelf 9, as shown in FIG. 3. This allows the retailer to advertise merchandise in a manner that will be more likely to attract the attention of consumers than a label or sticker attached to the leading edge 17. In the preferred embodiment as shown in FIG. 4, the label holder 3 is generally comprised of a front panel 24 and a back panel 25 between which is formed a channel 26. The back panel 25 is held by the link 4. The front panel 24 is attached to the back panel 25 by a interconnection 29, which allows the front panel 24 to be pulled away from the back panel 25 such that a sign or information sheet 23 can be inserted into the channel 26. The interconnection 29 is also resilient such that the front panel 24 is forced against the back panel 25, effectively holding the sign or information sheet 23 firmly in the channel 26. The interconnection 29 is enlarged to give structural strength to the label holder 3. A bottom edge 30 extends horizontally from the back panel 25, and an arcuate return 31, which is generally convex, connects the bottom edge 30 to the front panel 24.
The label holder 3 also has an overhang 38 which is cantilevered outwardly from the back panel 25 to overhang the front panel 24, effectively preventing dust and spilled liquids from entering the channel. The overhang 38 has a downward bend forming a short vertical lip 35. The short vertical lip 35 extents from the top flange 36 to protect the sign or information sheet from dust or liquid flowing downwardly from the edge of the shelf. The invention described herein is not limited to the particular label holder described above. Indeed, the label holder could take any of numerous alternative forms, such as a label channel with a top-hinged front panel as described in U.S. Pat. No. 6,568,113, which is incorporated herein by reference. A hinge 41 extends downwardly from the 90° bend and has a reduced thickness that allows the label holder 3 to flex up and out of the way when the price channel is attached to the shelf and products on the shelf below are removed.
FIG. 6 is an exploded view of the link 4 which shows the starting position of the label holder 3 in solid lines and lifted position in dotted lines. In one alternative embodiment, the link may be rigid; i.e., does not incorporate a hinge. In another embodiment, the label holder 3 could extend directly from or be an integral part of the front plate 16 the shelf grip 2.
While the invention has been described with reference to particular embodiments which has been shown in the figures and discussed above, it will be apparent to those skilled in the art that numerous variations, modifications and improvements may be made to the invention described herein without departing from the spirit and scope of the appended claims.
For example, but not by way of limitation, the shelving to which a channel, like the ones described herein is attached, typically includes a metal channel affixed to the front and rear edges of a shelf. The metal channel or rail provides structural support for the shelf and protects the edges of the shelf. The metal channel also typically provides a means by which the shelf may be connected (often temporarily) to a vertical component of the shelving structure. For certain applications, there be materials of which the shelf may be made that do not require the added structural strength afforded by the attachment of a metal channel or rail along the long edges of one or more of the shelves in the shelving structure. In such an instance, the shelf may have an upper and lower groove formed directly (e.g., cut from) the upper and lower surface of the shelf, and these grooves may receive the fingers of a channel made in accordance with the inventions shown and described herein. By eliminating the metal channel or rail, significant cost may be saved, and an extruded price channel as described and claimed herein could perform the edge protection that may have previously been provided by a metal channel or rail. In such cases, a much shorter metal component might be affixed to the ends of the shelf to provide a means for attaching the shelf to a vertical support without having the metal run the full length of the shelf.
