A transmission mechanism of an electromechanical lock includes a first rotating wheel and a rotatable structure. The first rotating wheel has a recessed portion and two first protruding portions. The recessed portion is arranged in a center of the first rotating wheel, and the two first protruding portions are separated from each other and protrude from a side surface of the recessed portion. The rotatable structure is arranged in the recessed portion. The rotatable structure includes a rotatable portion and two elastic members. The rotatable portion is rotatably arranged in the recessed portion. The two elastic members are separated from each other and connected to the rotatable portion, in which each of the elastic members has a second protruding portion close to the side surface of the recessed portion and is configured to interfere with each of the first protruding portions.

A casement window locking assembly comprises a locking handle, a housing, a locking bar, and a coupling member to transfer movement of the locking handle to the locking bar. The locking handle is movable between a locked position and an unlocked position. The assembly comprises first and second sensors, the first sensor comprising a first handle component secured to the coupling member and a second handle component mounted within the housing in order to detect the locking handle being in a locked position, the second sensor comprising a first window component mounted in the housing and a second window component being arranged to be mounted on the window sash in order to detect the window sash being located in a closed position. Rotational movement of the handle causes translational movement of the coupling member. Also, methods of providing a window status sensor system.

A deadbolt control and security system for preventing rotation of a deadbolt manual egress handle of a deadbolt lock is described herein. The system preferably includes a deadbolt interface unit and at least one actuator unit. The deadbolt interface unit has a manual mode (the deadbolt interface unit manual egress handle controlling locking and unlocking the deadbolt lock) and a remote mode (the at least one actuator unit controlling locking and unlocking the deadbolt lock). The deadbolt interface unit includes: a deadbolt interface unit manual egress handle; a gear train having a shaft coordinated with the deadbolt interface unit manual egress handle; a unit-handle coupler that interfaces between the deadbolt manual egress handle and the deadbolt interface unit manual egress handle via the shaft; and a clutch. Preferred systems prevent the deadbolt lock from being unlocked using keys and/or other bypass tools.

An exemplary latchbolt assembly includes a latchbolt, a locking sleeve, and a roller engaged between the latchbolt and the locking sleeve. The latchbolt is configured to drive the roller from a first position to a second position as the latchbolt moves from a projected position to a depressed position. The locking sleeve includes a blocking surface and a recessed portion. When the blocking surface is aligned with the roller, the locking sleeve retains the roller in the first position, thereby retaining the latchbolt in the projected position. When the recessed portion is aligned with the roller, the locking sleeve permits movement of the roller from the first position to the second position, thereby enabling depression of the latchbolt.

One embodiment relates to an exit device assembly. The exit device assembly includes a center case, a push pad movably mounted on the center case, and a mechanical case coupled to the center case, wherein the exit device includes an opening. The assembly also includes a sensor aligned with the opening, wherein the sensor is structured to detect a user from a distance through the opening and to generate an output signal in response to detecting the user. The assembly also includes a latch and a latch actuator. The assembly also includes a controller in communication with the sensor and the latch actuator, wherein the controller is structured to transmit an actuating signal in response to receiving the output signal from the sensor, wherein the latch actuator is configured to move the latch from the locked position to the unlocked position in response to the actuating signal.

Various implementations of an electric strike are described that includes a casing housing that includes a power source, a lock mechanism, circuitry powered by the power source, the circuitry being configured to authenticate a user, and electro-mechanically actuate the lock mechanism, and a rotor coupled to the lock mechanism, the rotor being powered by the power source and configured to situate the lock mechanism based on a lock state of the electric strike.

A lock module comprises a cylinder including a control latch configured to mechanically rotate between an extended position to prevent removal of the cylinder from a lock assembly, and a retracted position to allow removal of the cylinder from the lock assembly. A rotator is configured to enable the control latch to rotate between a locked position and an unlocked position. An actuation rod is configured to travel between a tab-blocking position maintaining the control latch in the extended position, and a retracted position allowing the control latch to retract into a retracted position. A control pin is configured to restrict the travel of the actuation rod in a control pin-blocking position in response to the rotator being rotated to a locked position and to retract from blocking the travel of the actuation rod to the control pin-unblocking position in response to the rotator being rotated to an unlocked position.

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.

A smart deadlock system according to an embodiment of the present invention includes a thumb-turn, a key cylinder, a connecting shaft connecting the thumb-turn and the key cylinder, and a sensor module. The sensor module may include a sensing unit to sense a rotation state of a rotation sensing element inserted onto the connecting shaft, and generate sensing information associated with the rotation state of the rotation sensing element, and a rotation information generation unit to receive the sensing information from the sensing unit, and generate rotation information associated with an extent of rotation of the rotation sensing element based on the sensing information. According to the smart deadlock system, it is possible to check the operation of the deadlock more accurately by sensing the rotation state of the rotation sensing element using the sensor.

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.
