An electronic cylindrical lock has a main body. The main body includes a slide member. The main body further includes a first clutch unit and a second clutch unit to drive the slide member. The first clutch unit and the second clutch unit are connected with a first handle and a second handle, respectively. The main body further includes a control unit for controlling the first clutch unit and the second clutch unit to be engaged or disengaged, so as to selectively allow the first handle and the second handle to drive the lock tongue, or selectively allow the first handle and the second handle not to drive the lock tongue.

An electronic lock with a latch assembly, an interior assembly, and an exterior assembly. The latch assembly includes a bolt movable between an extended position and a retracted position. The assembly includes an internal spring actuating mechanism. The assembly also includes a touch keypad subassembly configured to detect touches to at least a portion of its surface.

One or more embodiments describe a magnetic actuator 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 open or close the magnetic actuator. The semi hard magnet and the hard magnet are placed adjacent to each other. A change in magnetization polarization of the semi hard magnet is configured to push or pull the hard magnet) to open or close a digital lock realised with the magnetic actuator. The magnetic actuator can also be used to realise a valve.

Handle device for operating doors, windows and the like, comprising a first element (3), which is rotatable about an axis of rotation, a second element (8, 108, 208, 308), and a coupling device which is designed to selectively allow and prevent relative rotation about the axis of rotation between the first and the second element. The coupling device comprises; a first coupling member (15, 115, 215, 315, 515, 615) being connected to the first element; a second coupling member (8, 150, 208, 350) being connected to constituting the second element and at least one engaging member (19, 119, 219, 319, 519) which is displaceable between an engagement position in which it simultaneously engages the first and the second coupling members to thereby prevent relative rotation between the first and second element and a release position in which it is disengaged from at least one of the first and second coupling members to thereby allow relative rotation between the first and second element. 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). The engaging member and drive member comprise interacting contact surfaces arranged, during axial displacement of the drive member, to displace the engagement member from the release position to the engagement position. The drive member exhibits an interior recess (27, 127, 227, 327, 427, 527). A portion (36, 136, 236, 336, 436a, 536, 636) of the output shaft extends axially through the recess. A helical coil spring (38, 138, 238, 338, 538, 638) is arranged in the recess, concentrically about the output shaft, limitedly axially displaceable relative to the drive member and the output shaft and prevented from free rotation relative to the drive member or the output shaft. The output shaft or the drive member is provided with a radially extending spring engagement member (37, 137, 237, 337, 537, 637) which is arranged to engage the helical coil spring for axial displacement of the drive member relative to the output shaft upon rotation of the output shaft.

A lock with a handle assembly and a lock articulating assembly. The handle assembly has a handle member and a lock assembly. The handle member has a central bore and a locking plug groove. The lock assembly has a lock arm with a body positionable within the central bore. The body includes a central bore and a radial bore which is alignable with the locking plug groove. The lock assembly further has an outward locking plug configured to translate along the radial bore and selectively into the locking plug groove. The lock articulating assembly includes a slider (or a second cam), an actuator, a cam coupled to a motor. The cam is selectively engageable with the slider to rotate and/or translate the slider. The actuator is coupled to the slider, so that movement to the slider imparts movement of the actuator.

A deadbolt lock assembly comprising a retractable and extendable deadbolt, a housing, an outside member movably mounted on the housing, the member being normally disconnected from the deadbolt, and an operator input device on the housing, the device connecting the member to the deadbolt in response to presentation of an appropriate credential, such that a force applied to the member by the operator is mechanically transmitted to the deadbolt to move the deadbolt.

A door lock device is provided and includes: a housing, an acting assembly arranged in the housing and having a lock tongue, an operating assembly arranged in the housing and interlocked with an outdoor handle, and a regulating assembly arranged in the housing for a user to regulate the operating assembly into an interlocking state or an idle state. As such, in the interlocking state, the outdoor handle drives the acting assembly through the operating assembly to cause the lock tongue to extend or retract relative to the housing, and in the idle state, the operating assembly cannot drive the acting assembly and the outdoor handle cannot be interlocked with the lock tongue.

An electric lock includes a housing, a manual control member rotatably affixed to the housing, and a clutch mechanism. The clutch mechanism includes a clutch base rotatably affixed to the housing; a retractable plug arranged on the clutch base, wherein the retractable plug is radially movable relative to the clutch base; a driving member abutting against a first end of the retractable plug; and a motor configured to drive the driving member to move relative to the clutch base toward the shaft of the manual control member.

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.

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.
