Abstract
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.
