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 electronically-controlled manually-actuated deadbolt lock is provided. The electronically-controlled manually-actuated deadbolt lock includes an internal spring-actuated coupling mechanism that, when a user is authenticated, the coupling mechanism is placed in an engaged position that allows a deadbolt latch to be moved into a locked or unlocked position responsive to a manual rotation of a turn piece. Because the deadbolt latch is manually driven, a warped door condition can be overcome. Additionally, because the deadbolt latch is manually actuated, operation of the electronic motor may be decreased, which may increase battery life.

The first lever has a hole, configured for receiving the drive shaft, wherein the longitudinal axis of the drive shaft correlates with the first axis of rotation. The first lever further has first coupling means for providing a torque proof coupling with the drive shaft. A second bearing pivotably attaches the lever to a connecting rod, where-in the second bearing has a second axis of rotation, wherein the connecting rod has a first connecting element at the end of the connecting rod opposite to the lever. The first connecting element is moveably supported inside the first channel, wherein the channel walls limit a translation of the first connecting element in directions perpendicular to the first channel axis and enable a translation along the first channel axis.

An electronic lock cylinder that may be a direct replacement for a European-style standard cylinder is disclosed. The lock cylinder may include a core, a first shaft rotatably mounted in the core, and a second shaft rotatably mounted in the core and coaxial with the first shaft. A first cam and a second cam may be each rotatably mounted in the core and coaxial with the first shaft. The first cam may include a first lug and the second cam may include a second lug, where the first lug and the second lug may each be coupled to a deadbolt. A clutch may be disposed on the first shaft and shiftable from a first position to a second position, and a motor may be disposed in the core and operatively coupled to the clutch and configured to shift the clutch from the first position to the second position. When the clutch is in the first position, the first shaft is operatively coupled to the first cam, and the second shaft is decoupled from both the first cam and the second cam, when the clutch is in the second position, both the first shaft and the second shaft are operatively coupled to the second cam. The lock includes a first shaft rotatably mounted in the core and a second shaft rotatably mounted in the core and coaxial with the first shaft.

A drive member (21, 121, 221, 321, 421, 521, 621) is arranged axially displaceable, concentrically with said axis of rotation, by means of an electrical motor (6, 106, 206, 306, 406, 506) having a rotational output shaft (36, 136, 236, 336, 436, 536, 636).
