A component for use in a locking device such as a door lock or a padlock or bike lock that uses a shackle is disclosed. The component includes a body and a pair of rotatable plugs which sit within a cylinder of the body. One plug is connected to a handle and the other is connected to a lock release mechanism. A bridge selectively connects and releases the first and second plugs and an actuator, cooperating with biasing devices, is used to determine whether the bridge is in a connecting or releasing condition. This is in turn determines whether the component is acting to operate the lock in a locked or an unlocked condition.

Lock device (10) for an electronic locking system (126), the lock device (10) comprising an input member (12) arranged to rotate about an input rotational axis (16); an output member (18) arranged to rotate about an output rotational axis (22); an energy harvesting arrangement (26) configured to generate electric energy from rotation of the input member (12) in a first direction (28) about the input rotational axis (16); and a selective transfer device (54) movable between a locking state, in which the output member (18) cannot be rotated about the output rotational axis (22) by means of rotation of the input member (12) about the input rotational axis (16), and an unlocking state, in which the output member (18) can be rotated about the output rotational axis (22) by means of rotation of the input member (12) in the first direction (28) about the input rotational axis (16); wherein the transfer device (54) is powered by the energy harvesting arrangement (26). An electronic locking system (126) and a method are also provided.

The invention provides a digital lock (100, 1001, 1002) including at least two magnets. One magnet is a semi hard magnet (310) and the other magnet is a hard magnet (320). The hard magnet (320) is configured to open or close the digital lock (100, 1001, 1002). The semi hard magnet (310) and the hard magnet (320) are placed adjacent to each other. A change in magnetisation polarisation of the semi hard magnet (310) is configured to push or pull the hard magnet (320) to open or close the digital lock (100, 1001, 1002).

The invention provides a digital lock including at least two magnets. One magnet is a semi-hard magnet and the other magnet is a hard magnet. The hard magnet is configured to move to close the digital lock in the event of malicious attack, blocking the intruder thereby the magnets acting as a blocking pin, and the mechanical and/or electromagnetic energy of the attack is configured to move the hard magnet to seal the digital lock from the intruder.

A door lock disposed on a door leaf includes a casing, a bolt member, a latch member, an auxiliary latch member and a transmission unit. When the door lock is in an open state, the bolt member is retracted into the casing and held by the transmission unit. During a closing operation of the door leaf, the latch member and the auxiliary latch member are successively pushed into the casing to actuate the transmission unit, so that the transmission unit releases the bolt member when the door leaf is closed, and that the bolt member automatically projects out of the casing to lock the door leaf.

An electronic door lock includes a dead bolt moved by a deadbolt transmitting assembly, a spring-loaded latch bolt moved by a latchbolt transmitting assembly, a lock core rotated by a core transmitting assembly, and a spring-loaded prying resisting member. A monitoring unit includes sensors respectively corresponsive to those assemblies and the prying resisting member, and a security controller which performs a security procedure in accordance with position of those assemblies and the prying resisting member sensed by the sensors.

The invention provides a magnetic actuator (100, 1001, 1002) including at least two magnets. One magnet is a semi hard magnet (310) and the other magnet is a hard magnet (320). The hard magnet (320) is configured to open or close the magnetic actuator (100, 1001, 1002). The semi hard magnet (310) and the hard magnet (320) are placed adjacent to each other. A change in magnetization polarization of the semi hard magnet (310) is configured to push or pull the hard magnet (320) to open or close a digital lock realised with the magnetic actuator 100, 1001, 1002. The magnetic actuator of the invention can also be used to realise a valve.

A reversible electric door lock includes a clutch unit, a dead bolt unit and a handle unit. The clutch unit has an external driving member, two driving plates mounted at two sides of the external driving member, an internal driving member rotatably mounted in the external driving member, and a clutch pin movably disposed in the external driving member between an engaging position to allow synchronous rotation of the external and internal driving members, and a disengaged position to allow idle rotation of the internal driving member. The external driving member is rotated to actuate the dead bolt unit to switch to an unlatched position. The handle unit includes an internal operating handle coupled with one of the driving plates, and an external operating handle coupled with the internal driving member. The reversible electric door lock can be applied to left-hand and right-hand doors.

The present invention relates to a symmetrical and reversible-clutch mortise lock comprising a central follower, a pair of symmetrical lateral followers, each one located on one side of the central follower to be activated by square bars of handles, a spacer which makes the movement of the two lateral followers independent and a motor, which connects to an actuation lever and which is activated when an access code is validated. The lock further comprises a clutch housed and guided in an accumulator arm able to move linearly to be housed in both lateral followers such that the corresponding lateral follower, when activated by the motion of the door handle, pushes the clutch until it makes contact with the central follower and activates the latch of the lock.

An exemplary clutch mechanism includes a casing, first and second hubs rotatably mounted to the casing, an electrically-actuated drive assembly mounted within the casing, and a clutching lug movably mounted within the casing. The lug has an engaged position in which the lug couples the hubs for joint rotation and a disengaged position in which the hubs are rotationally decoupled. The drive assembly is operable to drive the lug between the engaged and disengaged positions to couple and decouple the hubs. The clutch mechanism is modular and self-contained within the casing such that the mechanism can be installed to each of a plurality of different lockset products without opening the casing.
