ABSTRACT:
A lock for safes and other security devices is disclosed having a case mountable on the inside of a safe door. A locking bolt in a slidable relationship within an opening in the case, moves between locked and unlocked positions. A gate, constrained in slidable relationship by and with the locking bolt, normally prevents the locking bolt from moving out of the locked position. An internal case extension obstructs the gate, when the lock is not activated, preventing the locking bolt from moving towards the unlocked position. A camming member, pivotally attached to the locking bolt, repositions the gate allowing the locking bolt to move out of the locked position. A solenoid driven armature, linked to the camming member and connected to the locking bolt, pivots the camming member and moves the locking bolt to the unlocked position. The locking bolt is held in the locked position when not activated by a spring. The solenoid is activated by an electrical unit having a keypad assembly mounted on the outside of the safe door. Coded input from the keypad assembly is wire fed through a small hole in the door to a receiver unit in the case that controls the solenoid. A novel relock member prevents the locking bolt from traveling to the unlocked position if the lock is tampered with through the small hole in the safe door.
