Bayonet locking system for vending machines and the like

摘要

A bayonet locking system for vending machines or the like is provided for locking and unlocking the machine preferably with a remotely controlled electronic operating device. The lock system includes at least one axially and rotationally movable bayonet that can be mounted selectively on the door of the machine and at least one receptacle receiving device disposed within the interior of the machine and positioned for engagement by the bayonet when the door is moved between an open position, an intermediate position, and a closed position. When the door is manually moved from the open position to the intermediate position, the bayonet advances into the receptacle and rotates to capture it in the receptacle. Then the bayonet axially retracts to pull the door into the closed position wherein a gasket disposed between the door and the vending machine is substantially uniformly compressed and sealed around its periphery. The locking device may also be provided with a remote control unit which provides instructions to the electronic circuitry of the locking mechanism. An axially rotatable pin with fins may be used with a bracket on either the door or machine to prevent prying of the door at opposite corners.
