ABSTRACT:
A locking mechanism which includes a rack-and-pinion-type gearing arrangement positioned on the interior surface of a security cabinet door surface is disclosed. The pinion-type gear is made rotatable by a shaft affixed thereto which communicates with the exterior surface of the door. The rack portion of the gearing arrangement is fixedly mounted to a plurality of shaft-like members which are adapted to be slidably displaced along the interior surface of the door. The shaft-like members position a plurality of bolt-like members about the perimeter of the door and function to extend those bolt-like members beyond the perimeter of the door and thereby secure the door when it is in a closed position. A bolt-like locking mechanism is positioned in conjunction or proximity to the shaft-like extensions whereby the locking mechanism may be employed to preclude the further displacement of the shaft-like extensions and thereby maintain the safe in a secured, locked position.
