A lock driver for a lock, including a lock cylinder body, an actuation attachment portion and an adapter structure. The lock cylinder body has a front end, a back end opposite the front end and an outer surface. The lock cylinder is positionable and rotatable within a bushing. The actuation attachment portion extends from the front end of the lock cylinder body. The actuation attachment portion includes an attachment interface that is structurally configured for coupling to a user maniuplatable structure. The adapter structure is associated with the back end of the lock cylinder body. The adapter structure is structurally configured to interface with an existing lock structure.

This invention relates to locking devices and particularly to an actuator assembly for a locking device with electronic control. The actuator assembly includes: a motor, having a drive shaft installed to a motor shaft, and a coil spring installed to the drive shaft, and further includes: a follower shaft capable of displacing in an axial direction in the coil spring, and a pin installed onto the follower shaft and rotatable into the coil spring, and the follower shaft is extended into the coil spring and slidably fitted to the coil spring. Compared with the prior art, this invention effectively maintains a radial limitation of the cylinder spring to overcome the vibration of the spring occurred during the rotation of the cylinder spring and the axial displacement of the follower shaft.

A door lock and an electrical appliance using the door lock. The door lock comprises: a switch housing; a pen core-like mechanism disposed in the switch housing; a control needle (state means) passing out of the pen core-like mechanism; and a manual unlocking pull rod mechanism. The manual unlocking pull rod mechanism is capable of moving towards the control needle and coming into contact therewith. The position of the control needle (state means) indicates the switch state of the door lock, such that when the door lock is in an unlocked position, further pulling of the manual unlocking pull rod mechanism has no effect on the door lock switch mechanism.

A vertical door latch assembly includes a housing and a bolt movably attached to the housing having a catch portion. A drive motor is located within the housing and is configured to selectively move a lock assembly between a locked position preventing movement of the bolt and an unlocked position allowing movement of the bolt. A controller is in electrical communication with the drive motor and is configured to direct the actuator lock assembly between the locked position and the unlocked position. A force sensor is in electrical communication with the controller configured to measured when a force exceeds a predetermined threshold.

Lock device for an electronic locking system, the lock device comprising an input member arranged to rotate about an input rotational axis; an output member arranged to rotate about an output rotational axis; an energy harvesting arrangement configured to generate electric energy from rotation of the input member in a first direction about the input rotational axis; and a selective transfer device movable between a locking state, in which the output member cannot be rotated about the output rotational axis by means of rotation of the input member about the input rotational axis, and an unlocking state, in which the output member can be rotated about the output rotational axis by means of rotation of the input member in the first direction about the input rotational axis; wherein the transfer device is powered by the energy harvesting arrangement. An electronic locking system and a method are also provided.

An over-travel mechanism configured to couple an input shaft and an output shaft in an exit device assembly. The input is connected to an actuator that linearly displaces the input shaft, and the output shaft is connected to a locking member of the exit device. The over-travel mechanism includes a link coupled to the output shaft, and a preloaded elastic member transmits force between the input shaft and the link. Movement of the input shaft from a first input shaft position to a second input shaft position causes the elastic member to urge the link from a first link position toward a second link position. Movement of the input shaft from the second input shaft position to a third input shaft position causes the elastic member to elastic member to elastically deform without moving the link from the second link position.

A lock includes a housing assembly, an actuatable lock assembly and a latching assembly. The actuatable lock assembly is positionable in at least a closed orientation and an open orientation. The latching assembly further includes a latch, a cam and a motor. The latch, having a cam profile, is movable between a locked position and an unlocked position. In the locked position, the actuatable lock assembly is maintained in the closed orientation. In the unlocked position, the actuatable lock assembly is positionable into an open orientation. The cam is rotatably mounted and has a first follower configured to intermittently coact with the cam profile of the latch, to, in turn, move the latch between the locked position and the unlocked position. The motor is coupled to the cam. Actuation of the motor causes rotation of the cam, resulting in movement of the latch between the locked and unlocked positions.

An electric door lock includes an operating device and a latch device operably connected to the operating device. An inner electronic device, an outer electronic device, and an electric driver are electrically connected by an electrical connecting module. An inner fixing member and an outer fixing member are fixed to a door. The inner fixing member includes an inner groove through which a first cable extends. The outer fixing member includes two first grooves. A second cable selectively extends through one of the two first grooves according to an assembling direction of the door. Thus, no matter whether the electric door lock is mounted to a left handed-door or a right-handed door, the electrical connecting module can avoid the mechanical structure of the electric door lock, providing convenient assembly.

A system to detect an unauthorized attempt to open a security lock (1-6), the system comprising a camera (10), which is directed towards the vicinity of the security lock; a communications connection between a camera (10) and a predefined mobile station (13); and a detector or sensor (8, 9), which is arranged to start the camera for transmitting a picture via said communications connection to the mobile station. The system further comprises a safety device (6) of the lock, having a safety latch (16), which has a locking position and an opening and, in which locking position, the mechanical opening of the lock with a key and/or rotary knob is prevented; at least one detector or sensor (8, 9), which is located in connection with the lock or door and arranged to detect at least one of the following events: (i) the presence of a key in the key channel (4) of lock, (ii) a movement or vibration of the door, (iii) a movement or vibration of a part of the lock. The control unit (7) of the safety device (6) is arranged to start the camera (10), when the detector or sensor (8, 9) detects one of above said events. The control unit (7) is arranged to start the camera (10) automatically only if the safety latch (16) of the safety device (6) is in the locking position and the detector or sensor (8, 9) detects one of above said events.
