A clutch assembly of an electronic cabinet lock includes a cam, a camshaft, a gear disc, a sleeve, a snap ring, and a steel ball. The cam includes a sleeve ring at its inner end and a swing arm at its outer end. The camshaft is sleeved within the sleeve ring by clearance fit, and the sleeve ring is sleeved within the sleeve by clearance fit. The gear disc is sleeved on the outer wall of the sleeve. The steel ball is mounted in a through groove of the side wall of the cam. The steel ball is located between the sleeve and the cam and is tangent to the camshaft. The camshaft is provided with a groove, and the groove allows the steel ball to fall in. The snap ring is engaged in an annular groove of the lower end of the camshaft for restricting the sleeve.

An electric lock body is provided. The electric lock body includes a housing, a driving mechanism, and a bolt. The driving mechanism includes a motor, a planetary gear assembly, and a cage. The planetary gear assembly includes a ring gear, a planet gear, and a sun gear. The motor is rotatably connected to the sun gear. The planet gear is rotatably connected between the sun gear and the ring gear. The cage is disposed at one side of the planetary gear assembly. The ring gear and the sun gear each abut against the cage. The planet gear is connected to the cage. The bolt is connected to the cage. When the cage rotates, the bolt is driven by the cage to move, to make the bolt switch between an unlocked state where the bolt is accommodated in the housing and a locked state where the bolt extends beyond the housing.

An electric lock includes a housing, a clutch mechanism and a manual control member. The housing is formed with a driving structure having a first inclined surface, a second inclined surface and a bottom surface. The clutch mechanism includes a driving member having a pushing structure, an elastic member arranged on the driving member for abutting against the driving structure, a rotating member having a pushed structure, and a motor for driving the driving member to rotate. The manual control member is connected to the rotating member. When the motor drives the driving member to rotate relative to the driving structure, the elastic member abuts against the first or second inclined surface to push the driving member to move toward the rotating member, so as to allow the pushing structure to abut against the pushed structure, in order to further drive the rotating member to rotate the manual control member.

Driven lock systems, fenestration units including the driven lock systems, and methods of operating the driven lock systems are described herein. The driven lock systems as described herein offer a combination of powered or motorized operation in addition to manual operation, with the opportunity for a user to manually switch the lock assembly between its locked and unlocked states as needed. The need for manual operation may arise if, for example, the system loses power, the controls of the system are unavailable, etc.

A lock and method for locking including an electronic cylinder assembly that may be a direct replacement for a standard cylinder in a standard mortise type door lock housing. The cylinder assembly may include a first shaft rotatably mounted in the core and a second shaft rotatably mounted in the core and coaxial with the first shaft. A clutch is disposed on the first shaft and rotationally fixed to the first shaft but axially shiftable. The cylinder assembly also includes a slider with a finger, where the finger is engaged with the clutch, and a motor is configured to shift the slider axially between a first position and a second position. In the first position, the clutch is disengaged from the second shaft, and in the second position, the clutch is engaged with the second shaft, such that rotation of the first shaft causes rotation of the second shaft.

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.

A clutch assembly of an electronic cabinet lock includes a cam, a camshaft, a gear disc, a sleeve, a snap ring, and a steel ball. The cam includes a sleeve ring at its inner end and a swing arm at its outer end. The camshaft is sleeved within the sleeve ring by clearance fit, and the sleeve ring is sleeved within the sleeve by clearance fit. The gear disc is sleeved on the outer wall of the sleeve. The steel ball is mounted in a through groove of the side wall of the cam. The steel ball is located between the sleeve and the cam and is tangent to the camshaft. The camshaft is provided with a groove, and the groove allows the steel ball to fall in. The snap ring is engaged in an annular groove of the lower end of the camshaft for restricting the sleeve.

A lock assembly comprises a driving member, a drive assembly, and an engaging member. The drive assembly comprises a drive connector operatively connected to the driving member, a lead screw operatively connected to the drive connector, a carriage configured and arranged to move along the lead screw, and an elongate member operatively connected to the carriage. The driving member is configured and arranged to rotate the drive connector, and the drive connector is configured and arranged to rotate the lead screw. Rotation of the lead screw moves the carriage along the lead screw and the elongate member moves with the carriage between locked and unlocked positions. The engaging member is configured and arranged to selectively engage the elongate member in the locked position.

The subject matter of this specification can be embodied in, among other things, a rotary lock assembly that includes an epicyclic gear assembly that includes a sun gear assembly having a sun gear axial aperture defined therein, a ring gear assembly, and a planet gear assembly mechanically engaged to the sun gear assembly and to the ring gear assembly, a lock motor configured to urge rotation of the sun gear assembly, and a screw lead extending axially through the sun gear axial aperture.

The present invention relates to structures of door locking devices that have a special additional function of self-sterilization, and more particularly, to structures of an electromechanical self-sterilising door handle assembly intended for mounting on latches or mortise locks with a bevelled latch bolt and a door handle spindle. The self-sterilising door lever handle assembly includes a rotation mechanism allowing to rotate handle from a standard operating position into a housing where it is sterilized by ultraviolet radiation and back.
