Abstract

A tray for a product vending machine including a flat base upon which product to be vended may be placed. A plurality of walls are attached to the base which define rows into which product is organized. A channel within the flat base houses a threaded shaft. The threaded shaft threadingly attaches to a product drive member.

Claims

1. A tray for a product vending machine comprising:

a flat base upon which product to be vended may be placed;

a plurality of walls attached to the base which define rows into which product is organized;

a channel within the flat base for housing a threaded shaft, the threaded shaft threadingly attached to a product drive member;

a mating surface associated with the threaded shaft such that when the mating surface is rotated, the product drive member is moved within the row wherein the mating surface is defined by a drive shaft comprising a gear that meshes with a gear of the threaded shaft to rotate the threaded shaft; and

wherein the product drive member is adapted to be biased toward one end of the row by a linear coil spring that wraps around the drive shaft and around a spring shaft in an opposite direction as the drive shaft.

2. The tray of claim 1 further comprising at least one resilient arm attached to the tray and biased in a position that substantially blocks product from exiting a row, the resilient arm being adapted to resiliently deflect when the product drive member forces a product past the resilient arm so that the product may be vended and return to its initial position to block the next product in the row.

3. The tray of claim 1 further comprising a pair of resilient arms located at an end of each row and biased in a position that substantially blocks product from exiting the row, the resilient arms being adapted to resiliently deflect when the product drive member forces a product past the resilient arms so that the product may be vended and return to their initial position to block the next product in the row.

4. The tray of claim 1 wherein the product drive member is adapted to be biased toward one end of the row.

5. The tray of claim 1 wherein the base of the tray comprises sections defining the rows, the sections interlocking with one another such that additional rows may be added or removed as required.

6. The tray of claim 1 further comprising an indicator for indicating the location of a row.

7. The tray of claim 6 wherein the indicator is a magnet.

8. The tray of claim 1 associated with a elevator for moving to the location of a desired row, extending a rotatable product drive to mate with the mating surface, and rotating the product drive to rotate the threaded shaft to force the product drive member to drive product within the row past resilient arms into the elevator.

9. A tray for a product vending machine comprising:

a flat base upon which product to be vended may be placed;

a plurality of walls attached to the base which define rows into which product is organized; and

a channel within the flat base for housing a threaded shaft, the threaded shaft threadingly attached to a product drive member;

a pair of resilient arms located at an end of each row and biased in a position that substantially blocks product from exiting the row, the resilient arms being resiliently deflectable to allow product to pass between the arms when product is forced past the arms;

a mating surface associated with the threaded shaft such that when the mating surface is rotated, the product drive member is moved within the row wherein the mating surface is defined by a drive shaft comprising a gear that meshes with a gear of the threaded shaft to rotate the threaded shaft; and

wherein the product drive member is adapted to be biased toward one end of the row by a linear coil spring that wraps around the drive shaft and around a spring shaft in a opposite direction as the drive shaft.

10. The tray of claim 9 wherein the product drive member is adapted to be biased toward one end of the row.

11. The tray of claim 9 wherein the base of the tray comprises sections defining the rows, the sections interlocking with one another such that additional rows may be added or removed as required.

12. The tray of claim 9 further comprising an indicator for indicating the location of a row.

13. The tray of claim 12 wherein the indicator is a magnet.

14. The tray of claim 9 associated with a elevator for moving to the location of a desired row, extending a rotatable product drive to mate with the mating surface, and rotating the product drive to rotate the threaded shaft to force the product drive member to drive product within the row past resilient arms into the elevator.
