An electric lock includes an input switching clutch for selectively transmitting the electric or manual driving force to the output line. The input switching clutch includes an outer ring that rotates together with an electrically driven input gear, and an inner ring which rotates together with an output gear. Wedge-shaped spaces are defined between the outer ring and the inner ring. Two rollers are mounted in each wedge-shaped space and are biased toward the narrow portions of the wedge-shaped space by a coil spring also mounted in the wedge-shaped space. The input switching clutch further includes an unlocking piece having crossbars inserted at both circumferential ends of the respective wedge-shaped spaces, and coupled to a manually driven input shaft so that its rotation can be transmitted thereto; and a torque transmission mechanism for transmitting the rotation of the manually driven input shaft to the inner ring.

A central access control system (10) includes a plurality of doors (44), a plurality of door locks (20) respectively mounted to the doors (44), a control device (33) connected to the door locks (20), and an unlocking device (40) for setting the control device (33) to be in an enabling state or a forbidding state. When the control device (33) is set to be in the forbidding state, the control device (33) outputs a forbidding signal to all of the door locks (20) to set the door locks (20) in a locking state. When the control device (33) is set to be in the enabling mode, the control module (33) outputs an enabling signal to all of the door locks (20), and a locking state or an unlocked state of a locking mechanism (24) of each door lock (20) remains unchanged.

An adaptive electric dual-controlled intelligent lock includes a mechanical clutching structure and an intelligent electronic control structure. The mechanical clutching structure includes a lock head, a lock cylinder and a lock tongue, wherein: the lock cylinder includes movable buckles, springs and a bearing. After being inserted into the keyhole of the lock head and then into the locked groove, a key is turned, the movable buckles move in an elastic range of the springs and drive the lock tongue connected with the bearing to swing, thereby realizing a mechanical unlocking process. The intelligent electronic control structure includes a PCB (printed circuit board), a motor and a shifting lever, wherein: a wireless control module is connected with an external mobile intelligent device; after the motor is started, the shifting lever pushes the movable buckles, so that the bearing drives the lock tongue to swing, thereby achieving an intelligent unlocking process.

A locking device that can be mounted into a rotating or swinging door is disclosed. The locking device can have a deadbolt. The locking device can detect the position of the deadbolt and/or whether the door is closed. The locking device can have a camera, microphone and speaker. The locking device can send images detected by the camera and audio detected by the microphones to a remote computer.

An electronic sensor and key operated lock is disclosed which provides users with the option to use at least one of a manually operated mechanism or for example a biometric sensor to unlock the lock. The lock integrates both the manually operated mechanism and a biometric sensor into one device. The manually operated mechanism and a biometric sensor are coupled to a common toggle switch so that operation of at least one of the manually operated mechanism and the biometric sensor moves the toggle switch and a shackle from locked and unlocked positions.

A twist handle latch assembly is provided for use on compartment doors of a utility vehicle. The assembly includes a plastic housing with a steel backer plate to which the latch pawl is mounted. A T-handle is rotatably mounted on the front of a housing with a post extending through the housing and the steel plate for connection to the latch pawl. Rotation of the handle rotates the latch pawl between locked and unlocked positions. A power actuator may be provided to remotely lock and unlock the latch pawl. A key cylinder actuator allows manual locking and unlocking of the latch pawl. A cam connected to the actuator has a window to receive a portion of the pawl in the locked condition.

A lock cylinder assembly includes a housing, a first cylinder disposed within a first bore formed in the housing, and a second cylinder disposed within a second bore formed in the housing, in which at least one of the first and second cylinders is an electronic cylinder. The lock cylinder assembly further includes first and second cams, in which each of the first and second cams are configured to actuate a door lock mechanism. The first cam is directly connected to the second cylinder so as to be rotatable with the second cylinder. The second cylinder and the second cam are rotatable with respect to each other so that the second cam does not rotate with the second cylinder. The second cam is rotatably coupled to the first cylinder so that the second cam rotates when the first cylinder is rotated.

A latching assembly for use on a pick-up truck, and particularly on a truck bed cover configured to sit over a truck bed section is provided. The latching assembly includes an electronic release assembly and a mechanical override system. An electronic release assembly includes a first rod coupled to a first electronic actuator and a second rod coupled to a second electronic actuator. The electronic release assembly also includes a first electronic actuator that selectively moves the first latch catch and the second electronic actuator that selectively moves the second latch catch. A switch is engaged to send a signal to the first and second electronic actuators to cause the first and second latch catches to disengage from the truck bed section. The first and second rods and the first and second electronic actuators also serve as part of a mechanical override system that selectively unlatches at least a portion of the truck bed cover from the truck bed section. The mechanical override system moves the first and second rods to mechanically cause the first and second electronic actuators, respectively, to manually move the first and second latch catches, respectively, to unlatch the at least the portion of the truck bed cover from the truck bed section as an alternative to moving the first and second latch catches by electrically moving the first and second electronic actuators.

The invention relates to a child safety locking mechanism 1 for a cupboard or drawer 2 comprising at least one movable door or drawer 3 and a fixed frame 2, and the locking mechanism 1 comprising: a latch assembly 5 and a catch part 4 each fitted on the movable door or drawer 3 and fixed frame, the latch assembly 5 including a latching arm 8 and a latching hook 9, and the catch part including a catch arm 6. The latching hook 9 is aligned to abut against the catch arm 6 in a locked position to prevent the movable door from being fully opened, wherein the latching arm is movable to an unlocked position in which the latching hook 9 is no longer aligned to abut against the catch arm 6 and the movable door or drawer 3 may be opened. Motor driven automatic release means are provided which are remotely actuatable to automatically move the latching arm 8 to the unlocked position when the automatic release means are actuated by a user. The latching arm 8 is moved downwards automatically by the remote actuation of the release arm 20 out of alignment with the catch arm 6. The release arm 20 is mounted on an axle which is rotated by a motor to just a sufficient extent to act on the latch arm 8 to move it out of alignment with the catch arm 6. The latch assembly 5 includes control means for the motor in the form of a circuit board, which also includes a Bluetooth or other radio wave receiver, located in a latch assembly casing 22.

Door with automatic opening and closing, including a door panel, a support column fixed to the door panel and suitable for rotating around its longitudinal axis in such a way to move the door panel between two end-of-travel positions, an electric motor for actuating the support column and a drive unit for transmitting the motion from the electric motor to the support column. The drive unit has a first drive element connected to the electric motor and a second drive element connected to the support column, wherein the drive unit includes a clutch unit that is interposed between the first drive element and the electric motor or between the second drive element and the support column. The door also has an automatic lock that completes the automation of the door by detectors.
