Abstract
A high security lock includes a lock bolt movable between extended and retracted positions, a bolt retraction gear coupled to the lock bolt, and a manually-driven gear train. When a controller verifies that user-input information is correct for unlocking the lock, the bolt retraction gear and manually-driven gear train are operatively coupled such that the gear train can drive the lock bolt from the extended position to the retracted position.
Claims17
A locking mechanism comprising:
- a lock bolt movable between extended and retracted positions;
- a bolt retraction gear operatively coupled to the lock bolt, the bolt retraction gear movable between engagement and disengagement positions;
- a manually-driven gear train including a first gear and a second gear, the second gear engaged with the bolt retraction gear in the engagement position;
- a user input device adapted to receive user input information;
- a controller adapted to store authorization information and verify user input information;
- and
- an actuator having a rotatable output element, the rotatable output element blocking movement of the bolt retraction gear and thereby preventing rotation of the second gear from the disengagement position to the engagement position until the controller verifies that the user input information matches the stored authorization information.

A locking mechanism comprising:
- a lock casing having a front surface and a spindle sleeve extending inwardly from the front surface;
- a lock bolt disposed at least partially within the lock casing and movable between extended and retracted positions;
- a manually-driven gear adapted to be operatively coupled to the lock bolt, the gear including a spindle shaft extending through the spindle sleeve and outside the lock casing;
- a controller including a circuit board adjacent to the front surface of the lock casing and having operational circuits controlling the coupling of the manually-driven gear to the lock bolt;
- and
- a circuit breaker device adjacent to the spindle sleeve and wired into the operational circuits of the controller, wherein drilling through the spindle sleeve will break the circuit breaker device and render the operational circuits of the locking mechanism inoperative.
3 more elements
A locking mechanism comprising:
- a lock casing having at least one mounting bolt disposed in a bolt receptacle;
- a lock bolt disposed at least partially within the lock casing, the lock bolt movable between extended and retracted positions;
- and
- a blocking member movable between a blocking position over the mounting bolt in the bolt receptacle and a non-blocking position that is not over the mounting bolt, the blocking member moving from the blocking position to the non-blocking position as the lock bolt moves from the extended position to the retracted position.
