A dead bolt lock system including a slider member operatively coupled to a dead bolt such that when the slider member is in a first position, the dead bolt is in an extended position. When the slider member is in a second position, the dead bolt is in the retracted position. The system also includes a first movable member positioned in a path of movement of the slider member and configured to be displaced by the slider member to allow the slider member to move to the second position. The system includes a first lock having a first condition preventing the displacement of the first movable member and a second condition allowing the displacement of the first movable member, a second lock having a first condition preventing the displacement of the first movable member and a second condition allowing the displacement of the first movable member.

An arrangement for a vehicle, in particular a rail vehicle, or for a building, has a control system adapted to control a plurality of different devices, a cabinet having a lock that can be locked in order to prevent access to a valuable device within the cabinet, and a control unit of the control system adapted to remotely control unlocking the lock. The control system is adapted to unlock the lock automatically if a predetermined condition is fulfilled or to unlock the lock on demand.

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.

The present invention relates to a safety locking device for interlocking a safety door, having a movable part designed for being fastened to a moving part of the safety door and having a locking element, and a stationary part designed for being fastened to a non-moving part of the safety door. The stationary part includes a receiving section having an opening for the reception of the locking element, where the locking element can be inserted into the receiving section from different insertion directions when the locking element is aligned in the insertion direction. The stationary part includes a latch selectively movable from a locking position into a release position.

Disclosed are various embodiments of lock devices, systems, and methods. A lock of the application can include an internal mechanism to permit backdriven operation and lost motion operation. In one form the lock can be made from an assembly of parts that have locating features that require one way installation/assembly. The lock can include an internal power source capable of driving electronics used to determine handedness of a door.

A locking device (40) including a first module (42) and a second module (44), one of the first module (42) and the second module (44) being attachable to a first face (22a) of a door panel (22) of an enclosure (10) to be locked and the other of the first module (42) and the second module (44) being attachable to a second face (22b) of a door panel (22) of an enclosure (10) to be locked, wherein the locking device (40) includes a mechanical locking mechanism (60) and an electronic locking mechanism (46).

An electrical lock may include a main body case; a dead bolt being movable between a locked position and an unlocked; a dead bolt moving element structured to move the dead bolt; a drive source structured to move the dead bolt moving element; a power transmission mechanism structured to transmit power of the drive source to the dead bolt moving element; a manual-handling component, which is placed at an outdoor side of the door, structured to manually move the dead bolt, being at the locked position, to the unlocked position; a manual unlocking mechanism to which the manual-handling component is connected; and a restriction member structured to restrict a motion of the manual-handling component, the restriction member being formed in, or fixed to the dead bolt moving element.

Systems and methods for providing secure locks having redundant access channels are disclosed. In some embodiments of the invention, the smart lock has a hardware processor, a power source, a cylinder, a button that forms a rose knob, and a rose protector. The rose knob and rose protector protect and conceal the hardware processor, the power source, and the cylinder. The rose protector forms an annular groove that slidably interlocks with the rose knob. The rose knob has a plurality of redundant access channels for receiving authentication information. The redundant access channels may include a biometric scanner for receiving biometric information, a passcode keypad for entering a token, or a wireless transceiver for receiving a token from a mobile device and transmitting a response to the mobile device. When the user cannot open the lock through the first redundant access channel, the smart lock is configured to allow access through a second access channel.

The present application provides a motor gearbox used in, for example, a smart door lock. The gearbox may comprise a housing, a motor disposed in the housing, a gearbox output shaft disposed in the housing; and a clutch mechanism comprising a main gear and a planetary gear meshing with the main gear. The main gear may be connected and driven by the motor, and the planetary gear may be selectively connected to the gearbox output shaft when the motor drives the main gear to rotate. When the main gear is rotating, the planetary gear may move in a circumferential direction of the main gear.

A device for a controlled locking or release of a safety-relevant, movable component (2), such as a protective door, protective cover of the like, with a movable blocking element (51) and with a self-locking drive unit (5, 17, 19, 21, 23, 27) controlling adjustment movements of the blocking element (51) between a locked position and a released position is characterized in that an actuator (33) is provided that can be moved by the drive unit (5, 17, 19, 21, 23, 27), said actuator being mechanically coupled to the blocking element for a transfer of the blocking element (51) into the released position brought about by the drive unit (5, 17, 19, 21, 23, 27) and being capable of decoupling for a transfer of the blocking element (51) into the released position brought about independently of the drive unit (5, 17, 19, 21, 23, 27).
