Abstract
A door and shelf interlock system for a vending machine comprises a vertically movable locking bar operatively coupled to the pivot structure of the door of the vending machine. The locking bar in a first position prevents any of the shelves from being pulled out from their normally retracted position inside the machine. A locking member is associated with each shelf. If the shelf is pulled out from its normally retracted position, the locking member engages the locking bar to prevent the door from being closed until the shelf is placed back into its retracted position.
