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.

Abstract: A plurality of vertical storage bins for packages of cigarettes are located behind a main pivotally mounted door which, when closed, covers all of the cigarette bins. An access door for each of the storage bins is mounted for vertical movement on the main door to selectively expose and close individual bins. A locking bar is supported on the main door to be selectively positioned in locking engagement with each of the access doors or free from the doors to permit movement thereof to expose the packages of cigarettes. A key operated locking arrangement includes a lock plate connected to and movable with the locking bar. The lock plate is selectively engageable by a key operated locking member and when so engaged the lock bar is held in its position engaging the access doors and holding them against movement and also locks the main door closed over the storage bins.

Abstract: In the blocked position of the central locking mechanism the locking bolt projects into the path of a blocking face of the drawer and can be elastically displaced when closing a drawer which is still open. In the open (unblocked) position of the central locking mechanism a stopping face which is arranged at a distance from the blocking face butts against a lever arm of the locking bolt when withdrawing the drawer and swivels the locking bolt into the blocking position; when closing the drawer the locking bolt is swivelled back into the release position.

Abstract: A locking system for a drawer file cabinet is disclosed. The system includes a locking assembly which is easily installed, removed and replaced without major effort and without major modification to the cabinet. This capability is provided through a novel arrangement of a cam plate pivotally connected to an insertable plunger lock, an internal support bracket uniquely adapted to receive and support and otherwise cooperate with the cam plate and plunger lock, and a reciprocating lock bar permanently mounted within a structural element of the cabinet. With the arrangement provided, only the cam plate and plunger lock are required to convert a cabinet incapable of being locked to a lockable cabinet.

Abstract: In the locked position of the central locking mechanism the locking bolt can be elastically displaced when a still opened drawer is being closed. In the unlocked position of the central locking mechanism, the locking bolt is swivelled into the blocking position when a drawer is being opened and swivelled back into the release position when the drawer is being closed.

Abstract: A gang lock assembly for locking the drawers of a cabinet includes a vertically extending locking bar behind each vertical row of drawers and a latch on each drawer engageable with the locking bar for locking the drawer. Each locking bar is pivotable about a vertical axis, and a connecting bar connects the locking bars for simultaneous pivoting movement between locking and unlocking positions. An actuator operable by one of the drawers is engageable with the locking bar behind said one drawer for pivoting the locking drawer to its locked position as the drawer is closed.

Abstract: A file-cabinet anti-tip device allows only one drawer to be withdrawn from a cabinet at a time. The device maintains cabinet-mounted drawer latches in drawer-unlocked positions when all of the drawers in the cabinet are closed, but moves the latches of the remaining drawers to drawer-locked positions in response to any one of the drawers being withdrawn from the cabinet. An actuating means includes a cabinet-mounted movable lock rod which is linked to the drawer latches, drawer-mounted cams and cabinet-mounted movable levers to move the lock rod in response to movement of the cams. The device of this invention can be easily integrated with conventional push-button-type file-cabinet locking mechanisms as well as combination-type locking mechanisms.
