In a vendor comprising a cabinet having a front door hinged at one side of the cabinet to swing open and closed, a plurality of shelves in the cabinet for holding items to be vended, each shelf being mounted for sliding movement in rear-to-front direction for being pulled out from a vending position within the cabinet to a loading position extending forward from the cabinet when the door is swung open, interlock means for locking the shelves in said vending position unless the door is swung to an open position enabling the shelves to be slid out without striking the door, and for locking the door in open position unless all the shelves are slid in to their vending position, thereby to prevent the door from being struck by a shelf if the shelf is pulled out with the door only partly open, and to prevent the door from being closed against a pulled-out shelf, said interlock means comprising: a locking member mounted in the cabinet at said one side thereof for movement between a first position wherein the door is unlocked and the shelves are locked in vending position, and a second position for locking the door in open position and unlocking the shelves; means interconnecting the door and said locking member for movement of the locking member by the door from its first to its second position when the door is swung to its open position, and vice versa; a lock bar mounted in the cabinet at said one side of the cabinet for up and down movement between a first position wherein the door is unlocked and the shelves are locked in vending position, and a second position wherein the door is locked in open position and the shelves are unlocked, said lock bar when in its first position being out of engagement with the locking member to enable movement of the locking member by the door; said lock bar being biased to its first position and being prevented by said locking member from moving to its second position when the locking member is in its first position, and being movable to its second position against the bias when the locking member is in its second position; a series of detents, one for each shelf, each mounted on the cabinet at said one side of the cabinet for movement between a first position wherein the respective shelf is locked in vending position and a second position wherein it releases the shelf and locks the door in open position; each shelf having a member at said one side of the cabinet engageable with the respective detent when the detent is in its first position and the lock bar is held in its first position by the locking member for locking the shelf in vending position; said member on each shelf moving the respective detent to its second position for release of the shelf when, with the lock bar in its second position, the shelf is pulled out, whereby, with the lock bar in its second position, one or more of the shelves may be pulled out at one time.
