摘要:
Existing small and medium-sized solenoid-operated locking containers are vulnerable to undesired impact-induced opening. An impact-resistant solenoid-operated locking container is disclosed. The container is protected against impact by the use of two solenoids oriented 180 degrees opposite each other. The solenoids are further protected against binding in a retracted position by T-shaped end caps, affixed to their retractable plungers, engaging notches cut into a movable plate. A silent, or nearly silent, impact-resistant solenoid, for use in an impact-protected locking container, is also disclosed, having the motion of its retractable plunger slowed and quieted by a viscous fluid such as damping grease.

An electromechanical lock includes an electronic circuit configured to read data from external source and match data against predetermined criterion. An access control mechanism includes a drive gear rotatable by electric power and a driven gear meshable with drive gear. Provided that data matches the predetermined criterion, the drive gear meshes with the driven gear and rotates the driven gear such that the access control mechanism is set to an open state. Provided that an external mechanical break-in force is applied to the access control mechanism, the drive gear remains stationary and the driven gear jams in the drive gear such that the access control mechanism remains in a locked state.

The invention relates to an electromagnetic doorlock with shock detection and power saving device comprises an electromagnet assembly and a corresponding attraction assembly. The electromagnet assembly is connected to a shock detection module and the attraction assembly has a pressing unit to press the shock detection module. When the door is opened, the electromagnet assembly does not supply power; when the door is closed, the electromagnet assembly with electromagnetic attraction attracts the attraction assembly and the pressing unit presses the shock detection module. That is, the electromagnetic doorlock usually stays in a low-energy attraction state; however, when a shock detection module is triggered, the electromagnetic doorlock returns to normal lock state for achieving power saving effect and control of the external force detection.

A micro motor locking bolt system (8) comprising a locking bolt (5) mounted inside a lock (11) in order to provide a locking function in electronic gates, drawers, cabinets, safes and similar structures. The locking bolt system has a locking position by entering into a lock housing (13) structured on the lock (11) and an unlocking position by removing from the lock housing (13). A motor (1) provides the necessary driving force in order for the locking bolt (5) to enter into and be removed from the lock housing (13). A worm gear (2) performs rotational motion around its own axis due to the driving force from the motor (1) and comprises grooved parts (2.1) thereon. Motion transmission members transfer the rotational motion of the worm gear (2) to the locking bolt (5) by transforming the rotational motion into linear motion.

A rotary mechanical latch for positive latching and unlatching of a rotary device with a latchable rotating assembly having a latching gear that can be driven to latched and unlatched states by a drive mechanism such as an electric motor. A cam arm affixed to the latching gear interfaces with leading and trailing latch cams affixed to a flange within the drive mechanism. The interaction of the cam arm with leading and trailing latch cams prevents rotation of the rotating assembly by external forces such as those due to vibration or tampering.

The invention relates to locking systems to realize locking function in embodiments such as electronic gates, drawers, cabinets, safes and similar things and it consists of linear motion transmission member (3) performing motion on a worm gear (2) to provide linear motion, angular motion transmission member (4) providing angular motion together with linear motion transmission member (3), guiding member (7) pushing, pulling and guiding angular motion transmission member (4) and linear motion transmission member (3) at the same alignment, motion transmission member (6) moving lock bolt (5) up and down, providing locking and unlocking, compressing the angular motion transmission member (4) in reverse direction and thus enabling the motor (1) to complete its cycle.
摘要:
An electronically controlled solenoid lock mechanism that remains locked when subjected to an impact type force. The lock utilizes the kinetic energy of a sliding bar during an impact to push on a lever with a fixed fulcrum such that the opposite end of the lever pushes against the core of the solenoid to keep it engaged with a latching mechanism. This prevents the unintentional opening a device to which the lock is attached with a mechanism that is energy, weight and cost efficient.

An electromechanical locking system (8) comprises a lock (12) and a key (14). The lock includes a cylinder (16), an electronic control unit (18) which is housed within the cylinder, a tailpiece (20), and an electrically-operable clutch mechanism (22) which is housed within the cylinder (16). The cylinder (16) is rotatably mounted to a first component to be locked and the tailpiece includes an adaptor (24) which is operable to interfere with the movement of a second component to be locked to the first component. The control unit (18) draws power from the key and is operable to generate an actuation signal for actuating the clutch mechanism (22) which releasably connects the cylinder and the tailpiece when actuated, thereby causing them to become rotatably coupled.

The present invention relates to a device and a method, in particular for transmitting a movement as well as corresponding forces or moments and in particular a rotational movement, wherein the transmission only takes place in a coupled state but not in a decoupled state. Devices and methods of this kind are in particular used in the field of lock devices, such as door or safe locks and the like. The device, in particular for transmitting a movement as well as corresponding forces and/or moments comprises a drive (2) and a take-off (3), wherein the drive and take-off are coupled via a coupling element in such a manner that in the decoupled state a movement of the drive causes a movement of the coupling element (4) which is not suitable for transmitting a movement of the drive to the take-off.

A lock (10) suited for locking safes and vaults comprises an access control system (12) and a locking device (14). The access control system (12) is provided with an anti-tampering system (24, 41 and 70) which is adapted to provide indication of illegal separation of the parts (30 and 60) housing the access control system (12). The locking device (14) includes a bolt assembly (20) which may be configured to provide a spring-loaded bolt or, alternatively, a deadbolt. The locking device (14) further comprises a re-locking mechanism (202 and 202null) adapted to prevent retraction of the bolt (20) upon displacement of the cover (108) of the lock casing (106).
