A door latch system comprises an interchangeable latch assembly for securing a door to a door frame. The interchangeable latch assembly comprises a head and a latch mounted to the head. The latch is moveable between latched and unlatched positions. A driven member is operatively connected to the latch, the driven member moveable to latch or unlatch the latch. The door latch system further comprises a universal actuating assembly removably couple-able to the interchangeable latch assembly. The universal actuating assembly comprises a mounting bracket and a driving member releasably coupled to the driven member. Actuation of the universal actuating assembly translates the driving member and the driven member, moving the latch to the unlatched position. A first interchangeable latch assembly may be swapped with a second interchangeable latch assembly without requiring modification of the universal actuating assembly.

The present disclosure relates to a bi-directional overrunning clutch, electronic door locks having bi-directional overrunning clutches, and methods of using the same. In certain embodiments, the electronic door lock includes a first locking mechanism for driving an inner wheel through a first torque to rotate a rotatable shaft to operate a locking device on a door by a user from outside, a second locking mechanism for driving inner wheel through the first torque to operate the locking device from an inside, a third locking mechanism for driving an outer wheel rotatable coaxially around the rotatable shaft through a second torque to operate the locking device electronically, and the bi-directional overrunning clutch. When outer wheel rotates at second torque, inner wheel and rotatable shaft rotate along with outer wheel, and when inner wheel rotates at first torque, outer wheel does not rotate along with inner wheel and rotatable shaft.

An electronic door lock includes a motor having a stator and a rotor that rotates relative to the stator. The rotor is configured to rotate a spindle operatively coupled to a deadbolt lock at a 1:1 drive ratio therewith. The spindle is engaged with the deadbolt lock to cause extension and retraction with rotation of the spindle

A vehicle includes a compartment mounted to a frame of the vehicle. The compartment includes a box coupled to the frame in a fixed position relative to the frame and a latch system coupled to the box to allow a user to access the box. The latch system includes a shape-memory alloy wire guided by a pulley during actuation of the latch system.

A lock state monitoring apparatus, a method, a lock driving apparatus and a lock assembly. The lock state monitoring apparatus includes: a rheostat and a first load, where a movable contact end of the rheostat is connected with a first end of the first load, and a first fixed end of the rheostat and a second end of the first load are configured to bear a first voltage; the movable contact end of the rheostat is configured to be connected with an output axis of a drive motor in the lock; the first fixed end and the movable contact end of the rheostat, or two ends of the first load, are configured to be connected with a main control board in the lock to output a first voltage signal to the main control board, so that the main control board determines a lock state according to the first voltage signal.

A smart lock for securing a door comprising: a housing mountable to the door; an actuator within the housing configured to actuate a lock mechanism between a locked position and an unlocked position, the lock mechanism including a latch bolt with an angled front face, the latch bolt configured to be retractable against a biasing force provided by a biasing means such that the door is closeable when the lock mechanism is in the locked position; and a receiver within the housing configured to wirelessly receive a signal to control operation of the actuator; a sensor mountable exclusively to the door so as to generate a signal indicative of the door beginning to move; a controller arranged to receive the signal indicative of the door beginning to move, the controller configured to control the actuator to actuate the lock mechanism in response to the signal indicative of the door beginning to move.

A remotely controlled cabinet assembly includes a cabinet unit that includes a central cabinet and a door that is hingedly coupled to the central cabinet. A plurality of locking units is each coupled to the central cabinet. Each of the locking units releasably engages the door for locking the door on the central cabinet. A control unit is coupled to the cabinet unit and the control unit is electrically coupled to each of the locking units. The control unit actuates each of the locking units to disengage and thusly unlock the door on the central cabinet. A keypad is coupled to the door and each of the locks disengages the door when an alpha-numeric code is entered into the keypad. An electronic device is carried by a user and the electronic device transmits an unlock command to the control unit for remotely unlocking the door on the central cabinet.

An electric locking device for selectively locking and unlocking a door to a door frame is provided. The device comprises a housing and a keeper movably connected to the housing. The keeper includes a keeper shaft having an axis of rotation. The keeper is rotatable about the axis of rotation between first and second rotational positions, and movable between first and second directional positions relative to the lock housing. The movement between first and second directional positions is generally linear, and the axis of rotation is configured to move relative to the lock housing as the keeper moves between first and second directional positions. When the keeper is in the first rotational and directional positions, the door is secured to the door frame by the keeper. When the keeper is in the second rotational and directional positions, the door is allowed to move away from the door frame.

An under counter safe for securing items and providing quick access includes upper and lower sections forming an interior cavity, with the upper section attachable to the underside of a countertop, desk, or other surface. A linkage mechanism may connect the upper and lower sections, allowing the lower section to be raised or lowered with respect to the upper section to allow access to the interior cavity. A dual locking mechanism may secure the lower section to the upper mechanism at two points, and a release mechanism may simultaneously disengage both locking points to allow access. The release mechanism may be manually or electronically activated.
