Abstract

A product management display system for merchandising product on a shelf includes using a trackless pusher mechanism that travels along a surface on which product is placed. The pusher mechanism of the invention also includes a pusher paddle and a floor that extends forward of the pusher paddle. A flat coiled spring or other biasing element may be operatively connected behind the pusher paddle and extend across the floor of the pusher mechanism and 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. With this configuration, the pusher paddle is prevented from tipping or bending backwards during operation. The invention 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.

Claims

1. A pusher mechanism for a product management display system, the pusher mechanism positionable on a surface of the display system, the pusher mechanism mounted to and held onto the display system by a coiled spring, the surface of the display system defining a plurality of apertures to permit debris or other materials to pass through, the pusher mechanism comprising:

a pusher surface, and

a pusher floor extending forwardly from the pusher surface, the pusher floor configured to permit at least one product to sit upon the pusher floor, the pusher floor positionable on and movable across at least a portion of the surface of the display system,

wherein the pusher mechanism sits on top of and does not extend below the surface of the display system, and is mounted to and held onto the display system only by the coiled spring,

wherein the coiled spring includes a coiled end which is positioned behind the pusher surface, and

wherein the pusher floor is substantially parallel to the surface of the display system.

2. The pusher mechanism of claim 1, wherein the pusher surface is concave shaped.

3. The pusher mechanism of claim 1, wherein the pusher floor defines a channel for receiving a coiled spring.

4. The pusher mechanism of claim 1, wherein the pusher floor defines a notch and the pusher surface defines a back surface for contact with a coiled spring.

5. The pusher mechanism of claim 1, wherein

the coiled spring is extendable across at least a portion of the pusher floor and operatively attached behind the pusher surface.

6. The pusher mechanism of claim 5, wherein the coiled spring extends across at least a portion of a top surface of the pusher floor.

7. The pusher mechanism of claim 5, wherein the coiled spring extends across at least a portion of a bottom surface of the pusher floor.

8. The pusher mechanism of claim 5, wherein the pusher floor defines a plurality of apertures.

17. The pusher mechanism of claim 1, wherein the pusher floor is configured to hold a bottle.

18. The pusher mechanism of claim 1, wherein the pusher floor defines a curve-shaped periphery floor portion.

19. The pusher mechanism of claim 1, wherein the pusher floor defines a periphery that further defines first and second curve-shaped periphery portions and a notch located between the first and second curve-shaped periphery portions.

20. The pusher mechanism of claim 1, wherein an end of the coiled spring opposite of the coiled end is configured to attach to the surface of the display system.

21. The pusher mechanism of claim 1, wherein the pusher surface defines a back surface which includes a plurality of support members.

22. The pusher mechanism of claim 21, wherein the coiled end of the spring is positioned between two of the plurality of support members.

9. A pusher mechanism for a product management display system, the pusher mechanism positionable on a surface of the display system, the pusher mechanism mounted to and held onto the display system by a coiled spring, the surface of the display system defining a plurality of apertures to permit debris or other materials to pass through, the pusher mechanism comprising:

a pusher surface; and

a pusher floor extending forwardly from the pusher surface, the pusher floor configured to permit at least one product to sit upon the pusher floor, the pusher floor positionable on and movable across the surface of the display system;

wherein the pusher mechanism sits on top of and does not extend below the surface of the display system, and is mounted to and held onto the display system only by the coiled spring.

10. The pusher mechanism of claim 9, wherein the pusher surface is concave shaped.

11. The pusher mechanism of claim 10, wherein the pusher floor defines a channel for receiving a coiled spring.

12. The pusher mechanism of claim 11, wherein the pusher floor defines a notch and the pusher surface defines a back surface for contact with the coiled spring.

13. The pusher mechanism of claim 12, wherein the pusher floor defines a plurality of apertures.

14. The pusher mechanism of claim 13, wherein the pusher floor is configured to hold a bottle.

15. The pusher mechanism of claim 9, wherein the coiled spring extends across at least a portion of a top surface of the pusher floor.

16. The pusher mechanism of claim 9, wherein the coiled spring extends across at least a portion of a bottom surface of the pusher floor.

23. A pusher mechanism for a product management display system, the pusher mechanism mounted to and held onto the display system by a coiled spring, the pusher mechanism comprising:

a pusher surface, and

a pusher floor extending forwardly from the pusher surface, the pusher floor configured to permit at least one product to sit upon the pusher floor, the pusher floor positionable on and movable across the surface of the display system, the surface of the display system defining a plurality of apertures to permit debris or other materials to pass through,

wherein the pusher does not extend below the surface of the display system,

wherein the pusher is mounted to and held onto the display system by the coiled spring,

wherein the pusher surface is substantially perpendicular to the pusher floor,

wherein the pusher floor is substantially parallel to the surface of the display system,

wherein the coiled spring includes a coiled end which is positioned behind the pusher surface,

wherein the pusher surface is concave shaped, and

wherein the pusher floor defines a periphery that further defines a first curved-shaped portion and also further defines a second curved-shaped portion.
