摘要:
A lock assembly is disclosed to lock a moveable structure to a fixed structure. The lock assembly includes an electric actuator operable to move a locking lug between first and second axial positions to correspond with a locked and unlocked configuration of the lock assembly. A resilient member can couple the locking lug to the electric actuator and drive the locking lug between the first and second positions.

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.
摘要:
A micropower passive electronic lock cylinder comprising an immovable cylinder body (3), a rotatable plug (1), and an electronic control circuit part is described. An electronic control circuit board (13) electrically connected with a micromotor (14) and locating switches (15, 16) is arranged in the rotatable plug (1). A lock pin (8), which is controlled by a displacement limiting cam (5) driven by the micromotor (14), moves between the immovable cylinder body (3) and the rotatable plug (1) to release or block the rotatable plug (1).

The invention includes a pilot controlled electromagnetic device (530) having a core housing (520), a coil (538), an armature (534) and primary load bearing device and a wrap spring (540) wrapped around a shaft (532). The pilot controlled device selectively tightens and releases the wrap spring (540) by creating and substantially nullifying an irreversible residual magnetic force between the armature (534) and the core housing (520) in order to brake the shaft (532).
摘要:
The device for electromagnetically securing a barrel (2) of a lock (1) has a rotary drive comprising a coil (12) and a rotor (7). The movable tumbler (4) can be taken out of engagement with the recess (3) in the locking barrel depending on the rotary position of the rotor (7). Distortion in the locked position is prevented by a stop on the front (11) of the rotor.
摘要:
Lock (1) with loading by electric control comprising two coaxial parts (32; 52, 41) mounted rotating and of which one is connected to a locking means for its motion and the other to an actuation means; at least one electromagnet comprising a magnet (45) and a coil (46), one of the elements of said electromagnet being mounted turning coaxially to said part to be rotatingly driven from a first to a second angular position when the coil receives an electric pulse; a link element (55) mounted on said first part and adapted to be displaced between one active positive position in mesh with the second part for rotatingly linking said first and second parts and a retracted position and a cam (65) carried by the movable element (46) of the electromagnet and adapted to act on said link element (55) for displacing it from its retracted position to its active position when the movable element (46) of the electromagnet passes from its first angular position to a second angular position.
