ABSTRACT:
A locking mechanism for use in a lightweight safe includes a toothed spur main drive gear mounted on a rotatable axis journaled through the safe's door. The main drive gear mechanically engages a pinion gear which in turn meshes with a vertically disposed rack gear. A second pinion gear also engages the rack gear and further engages a second drive gear. A securement locking mechanism, mounted to the interior face of the safe door proximate the main drive gear, is adapted for cooperation with the main drive gear for detachably restraining the main drive gear in a non-rotative orientation. The pinion drive gear/rack gear arrangement is adapted to transfer motion from the main drive gear around the aforesaid securement mechanism to the second drive gear. Each drive gear is mechanically associated with one or more laterally displaceable rack gears adapted to be displaced into engagement with the safe door frame to produce a locking engagement therewith.
