Abstract

Apparatus for advancing packaged goods on a shelf comprises an upright pressure plate carried on the end of a flexible belt. The belt is carried on a roll which is spring biased to wind the belt thereon so that a row of articles positioned along the belt and engaged by the pressure plate will be pushed toward the front of the shelf as each successive article is removed.

Claims

1. Apparatus for advancing shelved goods comprising:

a base member adapted to be mounted at the front of a shelf;

a cylindrical roll rotatably mounted on said base member;

a flexible belt secured to and extending rearward from said cylindrical roll;

means biasing said cylindrical roll to reel said flexible belt thereon;

an upright pusher member carried on the end of said belt to engage behind a row of articles positioned along said belt; and

lock means, selectively operated with said pusher member in any position, to secure said roll against rotation;

said lock means being mounted on said base member for movement thereon between a locking position wherein portions thereon engage portions on said cylindrical roll to prevent rotation of said roll and a neutral position wherein said portions are free of engagement.

2. The apparatus defined by claim 1 including:

a longitudinal slideway secured to and extending rearward from said base member; and

a slide member slidably received in said slideway;

said slide member being secured to the end of said flexible belt and carrying said pusher member.

3. The apparatus defined by claim 1 including:

5. The apparatus defined by claim 1 including:

a coaxial rod within said cylindrical roll;

said cylindrical roll being rotatable on said rod;

a coil spring secured between said cylindrical roll and said rod.

6. The apparatus defined by claim 1 wherein:

said lock means comprises;

a lock bar longitudinally slidable on said base member;

a polygonal member concentrically mounted on one end of said cylindrical roll;

a wide slot in said lock bar receiving said polygonal member for free rotation therein in one position of said lock bar; and

a narrow slot extending longitudinally from said wide slot and snugly receiving said polygonal member and engaging opposite sides thereof in a locking position of said lock bar.

4. means for adjusting the force of said biasing means.

7. Apparatus for advancing shelved goods comprising:

a slideway adapted to be mounted on a display shelf to extend from front to rear thereof;

a slide member slidably received in said slideway;

a pressure plate carried by said slide member;

a cylindrical roll rotatably mounted on said slideway;

a flexible tension member wound on said roll and secured at the distal end thereof to said slide member;

means biasing said cylindrical roll to wind said tension member thereon; and

lock means, selectively operated with said slide member in any position, to secure said roll against rotation.

said lock means being mounted on said base member for movement thereon between a locking position wherein portions thereon engage portions on said cylindrical roll to prevent rotation of said cylindrical roll, and a neutral position wherein said portions are free of engagement.
