ABSTRACT:
The safe has a five-sided box wtih a door mounted thereon to swing between opened and closed positions. A latch locks the door when in a closed position. An electronic locking arrangement responds to a digital access code for operating the latch in a rapid manner. A combination dial controlled mechanical lock is also employed for entering a combination code into the mechanical lock for operating the latch independently of the electronic latching arrangement. The five-sided box is made from pieces of sheet metal, one of which is folded along two spaced parallel lines to form three sides, to provide the box with few seams. Special hinges are provided inside the box for mounting the door swingably. The hinges are concealed and inaccessible when the door is closed, and can enable the door to be unhinged quickly by authorized persons to replace the safe door for repair or maintenance purposes.
