Merchandise display device
First Claim
1. A display device for feeding a column of serially stacked objects on a shelf forwardly on the shelf as the forwardmost object in the column is removed from the shelf, said device comprising,a shaft,a roller mounted upon the shaft and adapted to be rotatably journalled at the front of a shelf,a flexible belt wrapped around said roller and secured at one end to said roller,abutment means secured to the opposite end of said belt, said abutment means being engageable with the rearwardmost object in the column of objects stacked on the belt and being moved away from said roller as additional objects are placed upon the belt,torsion spring means operable to effect automatic rewinding of said belt onto said roller and forward feed of said objects on said belt when the forwardmost object in the column of objects is removed from the belt, andvariable means for adjusting the tension of said torsion spring means to vary the force with which said belt is moved forwardly on the shelf as objects are removed therefrom.

Abstract
A display device for feeding a column of objects forwardly on a shelf as the forwardmost objects are removed. The device comprises a bracket adapted to be secured to the front of the shelf and a flexible belt wrapped around a roller rotatably mounted within the bracket. Preferably, a low friction surface tape is secured to the top surface of the shelf over which the belt is movable. The device contains a torsion spring for maintaining a forward feed bias on the belt and a mechanism for adjusting the tension on the spring so as to vary that spring bias to enable the device to forward feed differing size and weight objects.

1. A display device for feeding a column of serially stacked objects on a shelf forwardly on the shelf as the forwardmost object in the column is removed from the shelf, said device comprising,
a shaft, a roller mounted upon the shaft and adapted to be rotatably journalled at the front of a shelf, a flexible belt wrapped around said roller and secured at one end to said roller, abutment means secured to the opposite end of said belt, said abutment means being engageable with the rearwardmost object in the column of objects stacked on the belt and being moved away from said roller as additional objects are placed upon the belt, torsion spring means operable to effect automatic rewinding of said belt onto said roller and forward feed of said objects on said belt when the forwardmost object in the column of objects is removed from the belt, and variable means for adjusting the tension of said torsion spring means to vary the force with which said belt is moved forwardly on the shelf as objects are removed therefrom.

2. A display device for feeding a column of serially stacked objects on a shelf forwardly on the shelf as the forwardmost object in the column is removed from the shelf, said device comprising
a shaft, a roller mounted over the shaft and adapted to be rotatably journalled at the front of a shelf, a flexible belt wrapped around said roller and secured at one end to said roller, abutment means secured to the opposite end of said belt, said abutment means being engageable with the rearwardmost object in the comumn of objects stacked on the belt and being moved away from said roller as additional objects are placed upon the belt, spring means operable to effect automatic rewinding of said belt onto said roller and forward feed of said objects stacked on said belt when the forwardmost object of the column of objects is removed from the belt, and variable means for adjusting the tension of said spring means to vary the force with which said belt is moved forwardly on the shelf as objects are removed therefrom.

9. An attachment adapted to be secured to a display shelf for converting that shelf into one for automatically feeding a column of serially stacked objects on the shelf forwardly on the shelf as the forwardmost object in the column is removed from the shelf, said device comprising
a bracket adapted to be removably secured to the front of a shelf, a shaft mounted within said bracket, a roller rotatably supported upon the shaft, a flexible belt wrapped around said roller and secured at one end to said roller, abutment means secured to the opposite end of said belt, said abutment means being engageable with the rearwardmost object in the column of objects stacked on the belt and being moved away from said roller as additional objects are placed upon the belt, spring means operable to effect automatic rewinding of said belt onto said roller and forward feed of said objects stacked on said belt when the forwardmost object in the column of objects is removed from the belt, and variable means for adjusting the tension of said spring means to vary the force with which said belt is moved forwardly on the shelf as objects are removed therefrom.
