A locking device for a lock including a box and a cover, such that the device can be isolated, which box includes therein a motor, a worm screw connected to the shaft of the motor, a locking shaft which is capable of sliding through a hole towards the outside of the box, and an elastic element with two ends, connecting the locking shaft with the worm screw, wherein one end of the elastic element is securely connected to the locking shaft and the other end is inserted between two threads of the worm screw such that, upon activating the motor, the worm screw rotates, moving the elastic element in order to drive the locking shaft, which transitions from being retracted to being extended and viceversa.

A low-voltage, direct current apparatus for controlling a door. The apparatus may comprise a mounting bar configured to be coupled to the door and a latch coupled to the mounting bar. The latch may comprise a locking lever, and an actuator may be configured to move the locking lever between a locked position in which the locking lever prevents movement of the latch to an unlocked position in which the locking lever allows movement of the latch.

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 clutch is disposed on the first shaft and rotationally fixed to the first shaft but axially shiftable. The lock 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.

A locking mechanism is selectively operable both electronically and mechanically by way of an integrated mechanical lock and motorized lock mechanism. A motorized lock mechanism is incorporated with a mechanical lock to provide for keyless access, while the mechanical lock and key system remains as a back-up. A toggle assembly is selectively positioned either mechanically via a first cam, or electronically via a second cam, both selectively operable independently of each other, without interference from each other, to move the toggle assembly to its unlocked position. A spring biases the toggle assembly to its locked position when the first and second cams are in their locked positions.

A tool box or tool cabinet (hereafter: “tool box”) is provided with a locking mechanism having a locked condition in which it prevents access to tools within the tool box, and an unlocked condition in which it allows access to tools within the tool box. An electric motor has a rotor, and is provided with a microprocessor and control circuit, coupled to the motor for controlling it. The microprocessor is adapted to receive Bluetooth signals when paired to a user's portable Bluetooth-enabled mobile device, The microprocessor and control circuit are effective, when the user's portable Bluetooth-enabled mobile device is sufficiently close to the control circuit to be detected, to energise the motor to rotate the rotor in a first sense, effective to disable the locking mechanism to allow access to the tools.

The electronic actuator of an electronic padlock according to the invention is arranged to turn the cam piece (5) to release the latch parts (7) from a locking state and to turn the cam piece (5) to hold the latch parts (7) in the locking state. The cam piece (5) comprises a cover part (5A) and a shaft part (5B). The cover part has a central hole (12) for the shaft part. The shaft part (5B) has a shaft pin (15), which is set into the central hole (12). The shaft part also has a connecting part 19, which is arranged to be in contact with the electronic actuator 4. The cam piece further comprises a spring (9,) which is between the shaft pin (15) and the cover part (5A). The spring comprises a first end (9A) and a second end (9B). The first end 9A is arranged to be in contact with the cover part 5A. The second end 9B is arranged to be in contact with the shaft part 5B. The spring is arranged to transmit turning force of the electronic actuator from the shaft pin 15 to the cover part 5A in the direction of said locking state.

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 lock includes a housing assembly, an actuatable lock assembly and a latching assembly. The actuatable lock assembly is positionable in at least a closed orientation and an open orientation. The latching assembly further includes a latch, a cam and a motor. The latch, having a cam profile, is movable between a locked position and an unlocked position. In the locked position, the actuatable lock assembly is maintained in the closed orientation. In the unlocked position, the actuatable lock assembly is positionable into an open orientation. The cam is rotatably mounted and has a first follower configured to intermittently coact with the cam profile of the latch, to, in turn, move the latch between the locked position and the unlocked position. The motor is coupled to the cam. Actuation of the motor causes rotation of the cam, resulting in movement of the latch between the locked and unlocked positions.

An intelligent lock, overlock, and lock system can be electrically controlled to open and close one or more locks. The lock, lock system, and method may function on a frequency selected to avoid cross talk, which permits numerous locks to function simultaneously on the same central system with little interruption or delay. A lock may be used as an overlock for an existing lock or be a primary lock and may include a pivoting engagement structure that engages a locking mechanism to provide added strength.

An exemplary trim assembly comprises an escutcheon, a drive spindle, a lock mechanism, a cam mechanism, and a driver. The drive spindle is mounted to the escutcheon for rotation about a longitudinal axis. The lock mechanism includes a lock gear movably mounted in the escutcheon. The cam mechanism includes a first cam defined by the escutcheon and a second cam defined by the lock gear. The driver is operable to rotate the lock gear between a first rotational position and a second rotational position. The cam mechanism is configured to longitudinally drive the lock gear from a first longitudinal position to a second longitudinal position as the lock gear rotates from the first rotational position to the second rotational position. Movement of the lock gear between the first longitudinal position and the second longitudinal position transitions the lock mechanism between a locked state and an unlocked state.
