Abstract

A bayonet locking system for vending machines is provided to lock and unlock the machine preferably with a remotely controlled electronic operating unit. It includes at least one motor driven axially and rotationally movable bayonet with an enlarged shaped head being mounted preferably on a gasketed door and at least one receptacle receiving device disposed within the machine interior positioned for engagement by the bayonet when the door is moved to an intermediate position. The bayonet advances into the receptacle and rotates to capture it in the receptacle and then axially retracts to pull the door into the closed position wherein a gasket disposed between the door and the machine is substantially uniformly compressed and sealed around its periphery. 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.

Claims

1. A method of locking a movable door relative to a stationary body comprising the steps of:

positioning an actuatable bayonet locking means having a shaped end within said door or body with said bayonet locking means being capable of both rotational and translational movements;

providing a stationary receiving means on the other said door or body adapted to receive the shaped end of said bayonet locking means;

motor driving said shaped end rotationally within the receiving means to capture the shaped end by the receiving means, and motor driving the shaped end longitudinally to either draw the door and body together or release the door from the body.

2. The method as claimed in claim 1 wherein the actuatable bayonet locking means is positioned totally within the door.

3. The method as claimed in claim 1 wherein the motor driven actuation of said bayonet locking means is remotely controlled electronically from outside the door and body.

4. The method as claimed in claim 1 wherein a compressible gasket is positioned between the door and body.

5. The method as claimed in claim 1 wherein the rotational and longitudinal driving of said shaped end occur sequentially.
