Brief Patent Description - Full Patent Description - Patent Application Claims
RELATED APPLICATION [0001] This application claims priority benefit of U.S. provisional patent application No. 60/654,399 filed on Feb. 19, 2005. FIELD OF THE INVENTION [0002] The present invention relates to improvements in display racks which can display a variety of products. More particularly, the invention pertains to a telescoping display rack for holding and displaying products. BACKGROUND OF THE INVENTION [0003] In the grocery industry, product displays are constructed to enhance the visibility of the product. It is important that products in the grocery stores remain "faced." "Faced" is a term used to mean that the product is in the front portion of the display case or shelf. With products such as paper towels, cereal, and other dry goods, employees of the store manually face the products. Some display racks are self-facing, meaning that, as long as there is more product in the rack, the products remain faced and are not in need of manual facing. For example, beverage racks generally are self-facing using gravity to move the bottles or cans to the front of the display. [0004] One known display rack currently in use is a peg system. A peg is anchored to the rear of a refrigerated case or display case. The package containing the product to be displayed must have a hole in the upper portion of the package. The hole in the package enables the package to slide through the peg and hang therefrom. The peg system, however, is not self-facing. Additionally, in order to rotate the product, the older product must be removed prior to placing the new product on the peg. Other known display technologies in use include shelving that, while removable, is not adjustable. Generally, these devices have fixed widths and products share space on the shelf. A desirable product display would be one that is self-facing and provides the flexibility of having multiple shelves in a single display case, while at the same time, making it easy to rotate the product displayed thereon. SUMMARY OF THE INVENTION [0005] In accordance with a first aspect, a display rack comprises a base adapted to be mounted to a wall, wherein the base defines an elongate slot having a retracted end, an extended end opposite the retracted end, a first groove and a second groove, wherein the first groove is positioned between the retracted position and the second groove, and a tray having a fin movable with respect to the slot as the tray slides along the base between a retracted position wherein the fin is generally adjacent the retractec end and remote from the first groove, and an extended position wherein the fin is at the second groove of the elongate slot. In accordance with another aspect the fin extends perpendicular to the elongate slot and the tray is movable to an initial position where the fin is positioned in the first groove. [0006] In accordance with another aspect, the fin has a first flange with a first width and a second flange with a second width narrower than the first width. The first groove is large enough to allow the fin to pass through, and the second groove is large enough to allow the second flange but not the first flange to pass through. [0007] From the foregoing disclosure and the following more detailed description of various preferred embodiments it will be apparent to those skilled in the art that the present invention provides a significant advance in the technology of product display racks. Particularly significant in this regard is the potential the invention affords for providing a high quality, low cost telescoping display rack which is easy to restock. Additional features and advantages of various preferred embodiments will be better understood in view of the detailed description provided below. BRIEF DESCRIPTION OF THE DRAWINGS [0008] FIG. 1 is an exploded perspective view showing a telescoping display rack in accordance with a preferred embodiment, having a tray and a base. [0009] FIG. 2 is a perspective view of the telescoping display rack in accordance with a preferred embodiment, shown in a retracted position. [0010] FIG. 3 is a perspective view of the telescoping display rack of FIG. 1, shown in a retracted position from the underside with teeth of a tray engaging corresponding openings in a base. [0011] FIGS. 4 and 5 are top and bottom views of the telescoping display rack of FIG. 1, shown assembled and in the retracted position. [0012] FIG. 6 is a perspective view of the telescoping display rack of FIG. 1, shown in an extended position. [0013] FIG. 7 is a perspective view analogous to FIG. 1, but showing a pusher in a locked position and showing optional bumpers formed as unitary extensions of the tray. [0014] FIG. 8 is an isolated perspective view of the pusher, including a pusher pocket adapted to receive a lock to lock the pusher. [0015] It should be understood that the appended drawings are not necessarily to scale, presenting a somewhat simplified representation of various preferred features illustrative of the basic principles of the invention. The specific design features of the display rack as disclosed here will be determined in part by the particular intended application and use environment. Certain features of the illustrated embodiments have been enlarged or distorted relative to others to enhance visualization and clear understanding. In particular, thin features may be thickened, for example, for clarity of illustration. All references to direction and position, unless otherwise indicated, refer to the orientation illustrated in the drawings. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS [0016] It will be apparent to those skilled in the art, that is, to those who have knowledge or experience in this area of technology, that many uses and design variations are possible for the telescoping display rack disclosed here. The following detailed discussion of various alternative and preferred features and embodiments will illustrate the general principles of the invention with reference to a telescoping display rack particularly suitable for use with products such as lunchmeat and related deli products. Other embodiments suitable for other applications will be apparent to those skilled in the art given the benefit of this disclosure. [0017] Turning now to the drawings, FIG. 1 shows an exploded perspective view of a telescoping display rack 10 in accordance with a preferred embodiment. A tray 18 is slidable over a base 20. The tray 18 is slidable between an extended position and a retracted position. The base 20 as shown preferably has a mounting bracket 22 at one end. The mounting bracket 22 has a series of projections 25 adapted to engage wall-mounted supports to mount the display rack. The base has a top side 98 and a bottom side 99, and has downwardly extending flanges 53, 54 which extend downward from the bottom side and provide enhanced strength for the base. [0018] The base 20 is generally rectangular in shape and preferably about the same shape and length as the tray 18. In addition to the mounting bracket 22, the base is provided with an elongate slot 24 having a retracted end 41 and an extended end 48. The slot has a first groove 42 and a second groove 43. Both grooves are preferably generally perpendicular to the elongate slot. The first groove 42 is close to but not at the retracted end 41. The second groove 43 is preferably positioned at the extended end 48. The base 20 is also provided with a pair of openings 44 and a pair of corresponding ramped surfaces 45. These openings 44 and ramps 45 cooperate with corresponding teeth 28 on the tray 18 (shown in FIGS. 3 and 5) to help with assembling the tray to the base.
