Abstract: A hinge assembly composed of a planar-surfaced mounting bracket, a pivoted connection means, and an approximately "J"-shaped leaf member is disclosed. The hinge, being configured to function in a concealed fashion, operates to pivotedly mount a recessed door within a security enclosure.
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.
Abstract: A lightweight safe having an unique door mechanism is disclosed. The lightweight safe has a front opening with a recessed door frame to accommodate a recessed door having dead-bolts which are positioned behind one edge of the door frame when the door is in a closed position and movable locking bolts which may be locked behind an opposed edge of the door frame when the door is in a locked condition. The opening mechanism involves the use of a locking shaft having a pair of roll pins which interact with a handle lever to provide a smooth acting opening mechanism and to provide shear means in the event the handle of the safe is forced when the safe is in a locked condition.
