Abstract

A security enclosure with an electronic lock, a concealed hinge door and lock wheel which operates a lock internal to the security enclosure. The electronic lock operates by a key pad into which a required security code may be entered. When the correct code is entered, a solenoid within the enclosure retracts moving a pin which allows the lock wheel to rotate. When the lock wheel is rotated, strike bolts extending into the top and bottom of the enclosure and left and right strike bars extending to the sides of the enclosure are retracted enabling the door to be pulled open. The door construction is such that there are no external hinges which may be drilled out, and the door itself is recessed so that it cannot be pried open. Attempts to turn the lock wheel when the solenoid is engaged have no effect because the wheel cannot be turned without breaking.
