Abstract

A vending machine includes first and second integrated dispensing systems mounted at front portions of adjacent product shelf dividers establishing at least first, second and third product queues. Each of the first and second dispensing systems includes first and second release mechanisms having a plurality of hinged plates supported by a frame. The plurality of hinged plates are selectively shifted into and out of corresponding ones of the first, second and third product queues, such that each product queue has associated therewith two opposing release mechanisms. Preferably, at least one of the first and second release mechanisms for each dispensing system includes a queue spacing member which is mounted to one of the hinged plates and projects into the product queue to establish a desired spacing between the release mechanisms.

4. The vending machine according to claim 3, wherein the queue spacing member of the first hinged plate of each of the first and second release mechanisms projects outward into one of the plurality of product queues when the first and second release mechanisms are in a product retention position.

5. The vending machine according to claim 2, wherein the queue spacing member of the first hinged plate of each of the first and second release mechanisms lies flat against the frame of each of the first and second release mechanisms when the first and second release mechanisms are in a product dispensing position.

6. The vending machine according to claim 2, wherein at least one of the plurality of hinged plates of one of the first and second release mechanisms includes a queue spacing member projecting outwardly therefrom.

7. The vending machine according to claim 2, further comprising:

a low torsion spring coupled to the kicker, said low torsion spring establishing a particular timing for deployment of the kicker.

8. A vending machine for storing articles to be selectively dispensed comprising:
