A lock clutch is provided to selectively couple a knob to a lock. In a locked configuration the clutch decouples the knob from the lock, so that rotating the knob does not operate the lock. In an unlocked configuration, the clutch rotationally connects the knob to the lock such that the lock may be operated by turning the knob. According to some embodiments, the knob may be a thumb turn and the lock may be a deadbolt lock.

An actuating device (12a, 12b, 12c) for a lock device (10) comprising a stationary structure (90) having a credential receiver (40) for receiving a credential input (42) from a user; an actuating element (16) rotatable about an actuation axis (18) relative to the stationary structure by direct manipulation by the user, where the stationary structure is arranged at least partly inside the actuating element; a locking member (24) movable between a locked position (106) and an unlocked position (no); and an electromechanical transfer device (y2a-y2c) arranged, based on the credential input, to adopt a disabled state (104), in which the locking member cannot be moved from the locked position to the unlocked position by rotation of the actuating element, and an enabled state (108) in which the locking member can be moved from the locked position to the unlocked position by rotation of the actuating element; wherein the credential receiver is at least partly arranged radially inside the actuating element with respect to the actuation axis.

The present disclosure provides an electro-mechanical lock assembly which illustratively includes a motor, a gear, a driver, a torque member, a housing, and a bezel. The motor is operable upon selective input. The motor is also coupled to the driver to engage both the gear and the housing when the motor is in operation. The bezel is attached to the gear such that when the driver is engaged with both the gear and the housing, manual rotation of the bezel will rotate the housing. The housing is attached to the torque member which is configured to move a latch such that when the bezel rotates the latch is moved.

Locking mechanisms and methods of operating the locking mechanisms are disclosed. In one example, a locking mechanism may include a main hub assembly coupleable with a deadbolt, a clutch assembly coupled to the main hub assembly, and an actuator assembly coupled to the clutch assembly. The actuator assembly may include an actuator operable to bias a carriage along a first direction to bring the clutch assembly and the main hub assembly closer to one another along a second direction, wherein the second direction is perpendicular to the first direction. The locking mechanism may further include a thumbturn assembly coupled to the clutch assembly, the thumbturn assembly comprising a thumbturn positionable on an exterior side of a door.

An electric lock includes a base, a driving module, a handle and a clutch member. The base has a first inclined surface. The driving module includes a driving member rotatable relative to the base and having a second inclined surface abutting against the first inclined surface, and a motor configured to drive the driving member to rotate. The handle is rotatably mounted to the base, and has a plurality of pushing structures. The clutch member includes a main body abutting against the driving member, and a pushed structure formed on the main body. Wherein, when the motor drives the driving member to rotate relative to the base along a first rotating direction, the driving member pushes the clutch member to move toward the handle, such that the pushing structure is configured to abut against the pushed structure to push the clutch member to rotate when the handle is rotated.

A lock assembly is disclosed to lock a moveable structure to a fixed structure. The lock assembly includes an electric actuator operable to move a locking lug between first and second axial positions to correspond with a locked and unlocked configuration of the lock assembly. A resilient member can couple the locking lug to the electric actuator and drive the locking lug between the first and second positions.

A transmission device of an electronic lock, disposed in a lock body, each of both sides of the lock body is provided with a rose assembly, connected respectively to a handle, to drive a driving seat to bring a latch bolt of a latch unit into action. The transmission device is controlled electronically, comprising: a positioning element, a motor, an elastic element, a rod, a clutch element, and a spring. The clutch element is slideable in the spindle, to move between a first position where the clutch element engages with the spindle and a second position where the clutch element disengages from the spindle, such that when the clutch element engages with the spindle, the spindle drives the driving seat, to retract the latch bolt of the latch unit.

A lock and method for locking including an electronic cylinder assembly that may be a direct replacement for a standard cylinder in a standard mortise type door lock housing. The cylinder assembly may include a first shaft rotatably mounted in the core and a second shaft rotatably mounted in the core and coaxial with the first shaft. A clutch is disposed on the first shaft and rotationally fixed to the first shaft but axially shiftable. The cylinder assembly also includes a slider with a finger, where the finger is engaged with the clutch, and a motor is configured to shift the slider axially between a first position and a second position. In the first position, the clutch is disengaged from the second shaft, and in the second position, the clutch is engaged with the second shaft, such that rotation of the first shaft causes rotation of the second shaft.

A door handle for actuating a mortise lock of a door with an output shaft and a handle facing away from the door. The output shaft and the handle have a common rotation axis and are connected to one another via an electromechanical clutch. The output shaft has a recess, on the side facing the handle, dimensioned for a coupling element that is axially displaceable between open and closed positions with a motor, while the handle has a receptacle dimensioned to accommodate the coupling element opposite to the recess. The door handle is particularly reliable when the motor drives a coupling (auxiliary) shaft on which and/or in which at least one coil spring is disposed non-rotatably and coaxially with respect to the stator of the motor. The auxiliary shaft has at least one protrusion engaging in an intermediate space between two neighbored windings of the coil spring to displace the coil spring axially as a result of rotation of the auxiliary shaft. The coil spring engages with the coupling element to at least preload the coupling element, as a result of the axial displacement of the coil spring, in a direction corresponding to such displacement.
