Abstract

A wall safe 10 uses an open front steel cabinet 20 mounted flush within a wall with a lock assembly 30 secured in one region and a portable deposit box 50 removably locked in place within another region. Lock assembly 30 includes a combination lock 24, an operating arm 35 enabled to turn when combination lock 24 is open, and a pair of live bolts 25 linked together for movement by arm 35 between locked and unlocked positions. A pair of dead bolts 19 arranged on an inner wall of cabinet 20 opposite live bolts 25 cooperate with lock assembly 30 in holding deposit box 50 securely in place. Opposite ends of the deposit box have internal steel channels 54 and 55 enclosing recesses into which the live and dead bolts enter through apertures 60 in the side walls of box 50. When locked, live bolts 25 pin together lock assembly 30, a crossbar 16 at the back of cabinet 20, and deposit box 50, making the system highly resistant to attack.
