Security box

Abstract

A security box utilizes a cam lock and latch system to secure an access door against unauthorized intrusion. The system further comprises a hooked cam latch and a set-off latch stop placed at some distance from the access door. This set-off latch stop may be a wall-piece cantilevered on a portion of the lock or another support, or it may be in the form of a bracket secured to the welded to the inside frame. The set-off latch stop prevents the cam latch from becoming separated from the cam lock during a pry attack. If the attack continues, the cam latch will deform and cause the cutout hook at the end of the cam latch to engage the set-off latch stop and bind the door to prevent it from opening. An additional internal bracket may divert force from the access door hinge during an attack
