摘要： 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.

摘要： An exemplary method relates to operating a door closer assembly including a closer body, a pinion rotatably mounted to the closer body, a motor including a motor shaft, and a bidirectional clutch connected between the pinion and the motor shaft. The method generally involves permitting, by the clutch, rotation of the pinion in each of a first direction and a second direction without transmitting rotation of the pinion in either direction to the motor shaft; sensing, with a sensor, a rotational position of the pinion; comparing, by a controller, the rotational position of the pinion with a desired rotational position; based upon the comparing, driving the motor to rotate the motor shaft; and by the clutch, coupling the motor shaft with the pinion in response to rotation of the motor shaft, thereby transmitting torque from the motor shaft to the pinion and urging the pinion toward the desired rotational position.

摘要： An exemplary noise-reducing mechanism for door hardware includes a housing, a damper, and a stop. The door hardware includes a first component and a second component, and an operational movement of the door hardware causes relative movement of the first and second components. The housing is mounted to the first component, and the damper is mounted to the housing. The stop is mounted to the second component such that the stop engages the damper during the operational movement. The damper is configured to slow the operational movement, thereby reducing noise generated by operation of the door hardware.
