A control structure of a door lock contains: a body, a slide plate, a clutch assembly, a head, a clutch assembly, and a guider. The body includes a chamber, a receiving groove, a motor, a drive gear, a trench, and a resilient element. The slide plate includes a holder, a trough, a lever, a lock cylinder, and a first connection orifice. The clutch assembly is received in the slide plate and includes a first annular ring, a second annular ring, and a third annular ring. The second annular ring includes two first cutouts, two second cutouts, and two recessed portions. The head includes a defining groove, a second connection orifice, and two bosses. The guider rotatably is fixed in the chamber and includes a space and at least two spiral indentations formed on an outer wall of the guider.

A lock for door includes a locking latch assembly, a lock rotor, a lock bolt and a rotating member, wherein the latch includes an upper rotor member, a clutch transmission set, a deceleration gear set, and a motor. When the deceleration gear set is driven by the motor, the deceleration gear set immediately drives the clutch transmission set to move the lock bolt. When the lock rotor is manually driven to rotate and the upper rotor member is connected to rotate, the upper rotor member pushes the clutch transmission set for a clutch action, so that the clutch transmission set only drives the lock bolt to move so as to selectively lock and unlock the lock for door.

A control structure of a door lock contains: a body, a slidable partition, a motor, a slide cylinder, a deadbolt, a latch, a first resilient element, and a second resilient element. The body includes a first cap, a second cap, an open segment, a close segment, a drive space, a holder, a groove, and an abutting post. The slidable partition is accommodated in the body and includes a slot, two spaced first driving extensions, a second driving extension, a through hole, two symmetrical hooks, and a seat. The motor is accommodated in the holder. The slide cylinder is received in the drive space. The deadbolt is movably received in the opening. The latch is accommodated in the notch. The first resilient element is positioned on the second positioning segment and the first positioning segment. The second resilient element is positioned on the first locating protrusion.

Provided are a lock cylinder and an unlocking key. The lock cylinder includes: a lock housing; a lock core, herein the lock core is rotatably arranged in the lock housing; a locking member, herein the locking member is movably arranged between the lock core and the lock housing and provided with a locking position and an unlocking position; a locking blade, herein the locking blade is movably connected to the lock core and capable of stopping or avoiding the movement of the locking member so as to lock or unlock the locking member; a driving assembly, herein at least part of the driving assembly is movably arranged relative to the locking member, and the driving assembly is capable of stopping or avoiding the movement of the locking member so as to lock or unlock the locking member.

An interchangeable electronic lock mechanism provides selective access to a motor controlled latching system including a motorized pin to lock and unlock a knob assembly. The lock mechanism may be used to replace key operated locking cores, on the exterior of a storage unit, with a plug and optional adapter inserted into a remaining shell housing, and a driver to control access to a storage unit. Manual rotation of the knob activates the drive assembly to control access to the storage unit. An optional break away security feature in the knob inhibits unauthorized unlatching of the lock. When the lock is unlatched, the knob rotates the drive assembly including the plug and adapter within the shell housing, and in turn, activates the driver to operate the lock assembly in the storage unit. An optional modular chassis assembly includes a removable array of components for testing, maintenance and repair.

An electric strike for a door frame, comprising: a body; a keeper moveably attached to the body for selectively retaining a latch bolt on a door; a blocking element movable between a blocking position in which the blocking element locks the keeper to prevent a latch from being moved past the keeper, and an unblocking position in which the blocking element unlocks the keeper to allow the latch to move past the keeper; an electronically controlled electric actuator for moving the blocking element between the blocking position and the unblocking position; and an override mechanism to override the electric actuator.

A lock including: a retractable knob; and a knob release mechanism for retaining the retractable knob in a retracted position, the knob release mechanism retains the retractable knob in the retracted position until a motor of the knob release mechanism is actuated by an input provided to a keypad located on a surface of the lock.

A door latch for an electrical domestic appliance includes a rotary member arranged to be rotationally movable between a closing rotational position and a release rotational position and is spring-biased in the direction towards the release rotational position, a movably arranged catch that is in an arresting engagement with the rotary member when the rotary member is in the closing rotational position, and a locking assembly that includes a movable locking member movable between an unlocking position and a locking position. The arresting engagement is releasable by an overlifting rotational movement of the rotary member. The rotary member is rotationally movable between a closing rotational position and a release rotational position and is spring-biased in the direction towards the release rotational position. The locking member, when transferred from the unlocking position into the opening position, causes the arresting engagement of the catch with the rotary member to be released.

An electromechanical component for a locking mechanism is provided. The locking mechanism includes a latching component having a latch member reciprocally movable between a locked orientation and an unlocked orientation. The electromechanical component comprises a drive member configured to be coupled to the latch member, an actuator operably coupled to the drive member, a temperature sensor for sensing an ambient temperature associated with the locking mechanism; and a printed circuit board (PCB) in communication with the temperature sensor and the actuator. When the PCB receives a control signal to move the latch member between the locked orientation and the unlocked orientation, and the temperature sensor senses that the ambient temperature is below a predetermined threshold temperature, the PCB is configured to direct a pulsed current signal to the actuator to move the latch member between the locked orientation and the unlocked orientation.

A locking apparatus and method for securing a door or window comprising a substantial controllable mechanical locking mechanism that secures the sliding door or window into the receiving channel such that the locking mechanism cannot be disengaged from the receiving structure by a manual force; prevents the door or window from being lifted out of a bottom track by mere manual force; is able to report the door or window status as closed or open and as locked or unlocked to a remote user; is able to be remotely locked and unlocked using an application running on a mobile device or computer, or, alternatively by accessing a web accessible portal from a mobile device, electronic device or computer; and is manually operable by a user in the event of a power outage. A manually operated embodiment is useful for use cases in which no electric power is available.
