GRAVITY FEED ROLLER STRIP SEATS FOR PLASTIC GLIDE TRAY
Disclosed are roller strip seats adapted to be used in conjunction with plastic glide trays for displaying beverages. The roller strip seats have a base and a plurality of rollers, where the base has a top, a bottom, a width having two edges and a length having two ends, a first and a second roller support bar on opposite sides of the width of the base along the length, where each roller support bar has a plurality of spaced openings configured to hold one of the plurality of rollers. The seat also has at least one locator disposed on the bottom and at least one locking element also disposed on bottom to align and lock the seat in the plastic glide tray. The rollers are placed in opposite spaced openings and are freely rotatable in the openings without pulling away from or out of the openings.
This application is related, and claims priority, to U.S. Provisional Application No. 62/374,025, filed on Aug. 12, 2016, that is incorporated herein in its entirety by reference thereto.
BACKGROUND 1. Field of the DisclosureThe present disclosure relates generally to gravity feed strip seats having rollers disposed therein or thereon as a mechanism for moving an item thereon via gravity, and methods for assembling the same. The present disclosure also relates to systems comprised of the gravity feed strip seats and plastic glide trays. More particularly, the present disclosure relates to gravity feed roller strip seats having rollers disposed therein or thereon that are configured to be disposed in a plastic glide tray that may be inclined, where the roller strip seats fit into the plastic glide tray and assist in moving an item disposed thereon and methods of assembly thereof.
2. Description of Related ArtCurrently, items such as beverages disposed in coolers are often placed in plastic glide trays to display the beverage in the coolers, both in big box supermarkets and in convenience stores. The basic function of the plastic glide tray is to hold the merchandise (beverage containers in bottles and/or cans) in proper alignment and to allow continual advancement of the merchandise toward the front of the plastic glide tray under gravitational force. Low cost, fixed dividers and easy installation are said to be the great advantages of such plastic glides, but steep pitches such as 12 to 16 degrees or more are often required to advance the merchandise to the front of the plastic glide tray. However, such a steep pitch for the incline is a great disadvantage in that the necessary pitch of 12 to 16 degrees reduces available vertical space in the coolers. The vertical space is of great value to the stores in that the greater the pitch angle, the fewer shelves can be deployed, and thus less merchandise can be displayed, in each cooler. Given the cost of the purchase and operation of the cooler, and that the stores cannot maximize inventory in the cooler for the given internal volume, profitability is reduced. In addition, such steep pitches may still fail to properly advance merchandise to the front of the plastic glide tray.
Modifications to improve the driving force for the advancement of merchandise in such plastic glide trays to attempt to (1) reduce the angle of pitch, (2) increase the quantity of merchandise that can be placed in the cooler, (3) and/or improve the actual advancement of merchandise disposed in the plastic glide tray and thereby improve the function, are practical issues of great marketing potential. Many methods have been tried but none is completely satisfactory, including spring-pusher systems such as mentioned below.
U.S. Pat. Nos. 7,497,342; 7,628,282; and 7,922,010 disclose product management display systems for merchandising both larger and heavier products that include the use of a pusher mechanism along with one or more roller assemblies. In combination, the product management display systems are said to improve the merchandising of products on the shelves, especially on horizontal or non-inclined shelves or surfaces. An exemplary embodiment of the patented product management display system includes a pusher mechanism mounted to a track that extends generally from the front of the shelf to the back of the shelf. The pusher mechanism is configured to urge product forward and toward the front of the shelf. At least one roller assembly is positioned beneath the product that is merchandised, and adjacent the track, to assist the pusher mechanism in urging the product toward the front of the shelf.
U.S. Patent Publication No. 2010/0276383 discloses a product management display system that includes a pusher mechanism mounted to a track that extends generally from the front of the shelf to the back of the shelf. The pusher mechanism is configured to urge product forward and toward the front of the shelf. At least one roller assembly is positioned beneath the product to be merchandised to assist the pusher mechanism in urging the product toward the front of the shelf. It is said that the disclosed product management display system may be mounted to a horizontal shelf or surface and heavier and/or wider product may be properly merchandised without the need to modify the system.
U.S. Pat. No. 8,312,999 discloses a product management display system for merchandising product on a shelf that includes using a trackless pusher mechanism that travels along a surface on which product is placed. The trackless pusher mechanism also includes a pusher paddle and a floor that extends forward of the pusher paddle. A flat coiled spring or other biasing element is operatively connected behind the pusher paddle and extends across the floor of the pusher mechanism to the front of the shelf. In use, the product to be merchandised may be placed on the coiled spring and on the floor of the pusher mechanism. Using this configuration, it is said that the pusher paddle is prevented from tipping or bending backwards during operation. In an alternative aspect, a mounting member may be used to mount the end of the coiled spring to the floor of the system. It is said that the disclosed display system may be used with the merchandising of product on horizontal or non-inclined shelves or surfaces, as well as with gravity-fed systems, or systems that use gravity as a mechanism to urge product toward the front of the shelf.
While the above systems are said to be an improvement to existing product management display systems, these systems are complex in design and construction, thus making them difficult to install without special tools and/or by a trained service person. The above systems are also difficult to keep clean and are subject to reduced efficiency as they become soiled with, e.g., spilled beverage.
Accordingly, there is a need for a system that advances items in a plastic glide tray without a spring-loaded pusher member.
There is a further need for a system that advances items in a plastic glide tray that reduces the number of working parts that need to be assembled or disassembled.
There is a further need for a system that allows for replacement of parts without the need for specially trained service personnel, thus reducing downtime and repair costs.
There is also a need for a system that allows for easy cleaning.
The present disclosure provides a simple but innovative solution to overcome the above problems and recognized needs of the prior art.
