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 actuating device (12) comprising an actuating element (14); an electric generator (16); and an electromechanical coupling device (18) configured to adopt a decoupled state, for decoupling the actuating element (14) from a locking member (22), and a coupled state, for coupling the actuating element (14) to the locking member (22); wherein the coupling device (18) comprises a blocker (26), a holder (38) and a release mechanism (40); wherein the holder (38) is arranged to adopt a holding position, in which the holder (38) holds the blocker (26), when the coupling device (18) adopts the coupled state; wherein the holder (38) is arranged to adopt a released position, in which the holder (38) does not hold the blocker (26), when the coupling device (18) adopts the decoupled state; and wherein the release mechanism (40) is arranged to mechanically force the holder (38) from the holding position to the released position by manual rotation of the actuating element (14) about the actuating axis (20).

An electric locking unit comprising a coupling device is described, the coupling device comprising an electric motor, a spring member, and a coupling member, the electric motor comprising a worm shaft with a helical winding. The coupling member is mounted axially slidably in the direction of extension of the worm shaft and has a contour configured for mechanically couple with a locking member. The spring member is connected, at a distal end portion, to the coupling member and, at an opposite proximal end portion, is axially slidably coupled with the worm shaft of the electric motor to convert a rotation of the worm shaft into a linear motion of the proximal end portion of the spring member. The worm shaft is idling when the spring member that is compressed or extended into a bias position reaches one of the two end position of the locking cylinder in the coupled or decoupled state. The proximal end portion of the spring member has a reduced diameter over at least one winding wrap over the worm shaft, such that the spring member is able to engage with the worm shaft via this at least one winding wrap.

Coupling arrangement for a lock device, the coupling arrangement comprising an input and an output element rotatable about a rotation axis; an engaging member movable between a first and second position; an electric motor arranged to affect movement of the engaging member between the first and second positions; a coupling member rotationally locked to the input element and axially movable relative to the input element between a decoupled position, where a rotation of the input element is not transmitted by the coupling member to a rotation of the output element, and a coupled position where a rotation of the input element is transmitted by the coupling member to a rotation of the output element; and a transmission mechanism arranged to transmit a rotation of the coupling member to a movement of the coupling member from the decoupled position to the coupled position when the engaging member adopts the second position.

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.

An exemplary lockset is configured for installation in a standard door preparation, and includes an exterior assembly, an interior assembly, and a center assembly connecting the exterior and interior assemblies. The exterior assembly includes an exterior escutcheon which houses a credential reader assembly including a multi-tech credential reader. The interior assembly includes an interior escutcheon which houses a control system. The center assembly includes a chassis, an outer surface of which may define a channel. The credential reader assembly is in communication with the control assembly via a wire harness, a portion of which may pass through the channel.
