High security lock mechanism |
摘要 |
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.
