A self-powered electric lock includes a lock bolt and a first engagement element having disengaged and engageable positions. An electric actuator includes an output operative to move the first engagement element to its engageable position. A manually operated rotatable member is operatively coupled to the first engagement element when the first engagement element is in its engageable position. A lock bolt drive mechanism is coupled to the lock bolt and to the first engagement element when the first engagement element is in its engageable position. The movable output moves the first engagement element to its engageable position upon input of correct electronic data. An electricity generator is coupled to the manually operated rotatable member. The electricity powers the electric actuator and an electronic data input device. The manually operated rotatable member is also used to actuate the lock bolt drive mechanism and retract the lock bolt.

High security lock mechanism

A locking mechanism adapted to be placed in locked and unlocked positions. The locking mechanism includes a lock-bolt mounted for movement between locked and unlocked positions and a first engagement element having disengaged and engageable positions. An electric actuator having a movable output drives the first engagement element to the engageable position. A manually operated second engagement element can be engaged with the first engagement element in its engageable position. A lock-bolt drive mechanism is operatively coupled between the lock-bolt and the first engagement element. A slidable element responds to a movement of the manually operated second engagement element and slides linearly between engaged and disengaged positions. The slidable element cooperates with the lock-bolt drive mechanism to enable manual movement of the lock-bolt between the locked and unlocked positions thereof such that the disengaged position of the slidable element corresponds to the locked position of the lock-bolt.

A safe locking mechanism has an engagement element movable from a disengaged position to an engageable position in response to a small amount of electrical power. When in its engageable position a mechanical linkage assembly is driven by the engagement element to unlock a lock-bolt. The mechanical linkage assembly includes a low inertia pivoting cam which interacts with a lock lever of the locking mechanism to move it to an unlocking state. Electrical power is generated solely while the user manually inputs a combination code, and a microprocessor controls storage and delivery of this power to put the engagement element into its engageable position. Once the desired engagement is obtained, the lock-bolt is moved from its locking to its unlocking position manually. Subsequent unlocking requires another entry of the code input.

A safe locking mechanism has an engagement element movable from a disengaged position to an engageable position in response to a small amount of electrical power. When in its engageable position a manually operated element moves the engagement element to unlock a lock-bolt. In one embodiment, the engagement element is connected to the rotor of a low power, low-friction electric motor having magnetic detents corresponding to the disengaged and engageable positions. Electrical power is generated solely while the user manually inputs a combination code, and a microprocessor controls storage and delivery of this power to put the engagement element into its engageable position. Once the desired engagement is obtained, the lock-bolt is moved from its locking to its unlocking position manually. Subsequent unlocking requires another entry of the code input.
