  • Patent number: 5439136
    Abstract: A merchandise push-out device for a vending machine, which pushes forward the lowermost piece of merchandise in a merchandise stocker in which merchandise is stacked vertically and supports the remaining pieces of stacked merchandise in a substantially horizontal position. A rocking arm has an upper end which is rocked back and forth from a support shaft by a motor drive. A merchandise push-out roller is attached to the upper end of the rocking arm, and a merchandise support roller is attached to the push-out roller below it with a link. When the rocking arm is rocked, the push-out roller, utilizing vertical play in the rocking arm, is moved forward in the horizontal linear direction to push-out the lowermost piece of merchandise. While the lowermost merchandise is being pushed out, the upper merchandise is supported by the support roller, which is pulled into place by the push-out roller. The push-out member and the support member work in tandem to prevent the upper merchandise from tilting extensively.
