An example lock apparatus generally includes a housing, a latch spindle, a drive spindle, an electronic lock mechanism, and an override mechanism. The latch spindle is mounted for rotation relative to the housing, and is operable to actuate a latch mechanism. The drive spindle is mounted for rotation relative to the housing. The electronic lock mechanism is disposed in the housing, and is operable to selectively couple the drive spindle with the latch spindle. The override mechanism is disposed in the drive spindle, and is operable to selectively couple the drive spindle with the latch spindle.

A clutch assembly for a lock includes a driver (1), having a driver shaft (9); a coupler (3); and a follower (2). The driver (1), the coupler (3) and the driver shaft (9) are configured to rotate concentrically together. The coupler (3) is configured to move along the central axis of the driver shaft (9) to couple to or decouple from the follower (2). The driver (1) and the follower (2) are configured to rotate concentrically together when the coupler (3) is engaged to the follower (2), and wherein the driver (1) and the follower (2) are configured to rotate independently when the coupler (3) is disengaged from the follower (2).

Actuator (10) comprising a base section (14,14a,14b); a permanent magnet (18,18a,18b); an electro permanent magnet (20, 20a, 20b); a coil (22, 22a, 22b) located around the electro permanent magnet (20, 20a, 20b); a power controller (24, 24a, 24b); and a movable member (28) comprising at least one magnetic target section (36), the movable member (28) being arranged to move to a first position (12) relative to the base section (14,14a,14b), when the electro permanent magnet (20, 20a, 20b) adopts a first polarity, and arranged to move to a second position (46) relative to the base section (14,14a,14b) due to a magnetic field generated by the permanent magnet (18,18a,18b) and the electro permanent magnet (20, 20a, 20b) in combination and acting on the magnetic target section (36), when the electro permanent magnet (20, 20a, 20b) adopts a second polarity. A lock device (50), a handle device (86) and a method are also provided.

An electronic lock includes a latch member and a clutch mechanism mounted on the outside of the lock cylinder and including a clutch unit, a driving unit and a control module. The clutch unit includes a rotatable seat having a first engaging portion, an accessible knob, and a clutch seat having a second engaging portion. The clutch seat is movable relative to the rotatable seat between an unlock position and a lock position, where the second engaging portion engages and disengages the first engaging portion, respectively.

A control unit 1 for the lock of a safe having a front housing part 4 and a rear h housing part 3. A controller 6 is integrated in the control unit 1 that, when a correct combination is entered in the keypad 5, moves a module through a motor 11 in the number of turns corresponding with this combination. The module has a transmission board 8 integrated in the housing 2 of the control unit 1 and a bolt 9 for actuating the safe's lock.

A removable lock core for use with a lock device having a locked state and an unlocked state is disclosed. The removeable lock core may include a cam member tailpiece which is moveable between a first position relative to a lock core body which corresponds to the lock device being in the locked state and a second position relative to a lock core body which permits removal of the removeable lock core from the lock device which corresponds to the lock device being in the unlocked state. The removeable lock core may include an electro-mechanical drive assembly which in a disengaged state is decoupled from the cam member tailpiece and in an engaged state is coupled to the cam member tailpiece. A cam lock having a locked state and an unlocked state for use with a catch is disclosed.

An electronic lock cylinder contains: a receiving sleeve, a lock head, a fastener, a rotation element, a rotatable actuation element, a driven element, a drive motor, a resilient element, an operation element, a locking element, and a locating cap. Thereby, the drive motor moves clockwise or counterclockwise to drive the rotary column to rotate 90 degrees and to simultaneously actuate the driven element, the drive motor, the resilient element, and the engagement projection of the operation element to move forward or backward to rotate or rotate idly in the notch of the locking element, thus saving energy and obtaining environmental protection.

A clutch includes an outer box and an intermediate member pivotably connected to the outer box. The intermediate member is coupled with an outer handle to pivot therewith. A torsion spring is disposed between the intermediate member and the outer box and biases the intermediate member to an initial position. A coupling member is pivotably mounted between the intermediate member and the outer box and is operatively connected to a first latch of a latch device of a lock device. When the coupling member and the intermediate member are jointly pivotable, pivotal movement of the outer handle causes the first latch to move from the latching position or the unlatching position. When the coupling member is not jointly pivotable with the intermediate member, pivotal movement of the outer handle is incapable of causing movement of the first latch. A lock device with the clutch is also disclosed.

An actuating device (12) comprising a stationary structure (20); an actuating element (22) rotatable relative to the stationary structure (20); an electric power source (24, 82); a spindle (26) arranged to be rotated by rotation of the actuating element (22); a locking member (28) movable between a locked position (66) and an unlocked position (86); an electromechanical transfer device (30, 84) arranged in the spindle (26), the transfer device (30, 84) being configured to adopt a locked state (68) and an unlocked state (78); a receiver device (34) fixed with respect to the spindle (26), the receiver device (34) being electrically connected 62 to the transfer device (30, 84); and a transmitter device (32) fixed with respect to the stationary structure (20) and arranged to be electrically powered by the power source (24, 82), the transmitter device (32) being configured to wirelessly transmit power to the receiver device (34).

An electronic lock includes a latch member and a clutch mechanism mounted on the outside of the lock cylinder and including a clutch unit, a driving unit and a control module. The clutch unit includes a rotatable seat having a first engaging portion, an accessible knob, and a clutch seat having a second engaging portion. The clutch seat is movable relative to the rotatable seat between an unlock position and a lock position, where the second engaging portion engages and disengages the first engaging portion, respectively.
