ABSTRACT:
An electronic gun lock for a firearm which includes an electronic lock enclosure, a locking shaft member, and an optional locking shell. The locking shell, if used, is disposed within a bullet chamber of the firearm, and is adapted to fit both the firearm's bullet chamber and the locking shaft member. The locking shaft member includes an axially moveable elongated locking rod which is moveable between an unlocked position where the locking rod is slidable with respect to the locking shell (or bullet chamber if no locking shell is used) and a locked position where the locking rod is restrained against axial movement with respect to the locking shell (or bullet chamber). A releasable actuator contactly engages and moves the locking rod between the unlocked position and the locked position. A solenoid includes a moveable arm and is responsive to a control signal to cause the moveable arm to allow the actuator to move the locking rod between the unlocked position and the locked position. An electronic combination code decoder is provided for decoding a sequence code entered through a pair of combination pushbutton code switches and for generating the control signal allowing the solenoid to be energized when the sequence code is correct.
