  • Publication number: 20230313585
    Abstract: An exemplary modular hold-open device is configured for use with a door closer comprising a body, a pinion rotatably mounted to the body, and an armature connected with the pinion. The modular hold-open device is configured to be mounted to the door closer, to selectively prevent rotation of the pinion by exerting on the pinion a resistive torque in a door-opening direction, and to cease exerting the resistive torque in response to a door-closing torque on the pinion exceeding a threshold torque to thereby permit rotation of the pinion in the door-closing direction.

  • Patent number: 11739562
    Abstract: An exemplary clutch mechanism includes a casing, first and second hubs rotatably mounted to the casing, an electrically-actuated drive assembly mounted within the casing, and a clutching lug movably mounted within the casing. The lug has an engaged position in which the lug couples the hubs for joint rotation and a disengaged position in which the hubs are rotationally decoupled. The drive assembly is operable to drive the lug between the engaged and disengaged positions to couple and decouple the hubs. The clutch mechanism is modular and self-contained within the casing such that the mechanism can be installed to each of a plurality of different lockset products without opening the casing.

  • Patent number: 11443572
    Abstract: A lockset including a bolt mechanism, an exterior assembly, an interior assembly, a driving tailpiece, and a driven tailpiece. The bolt assembly includes a bolt having an extended position and a retracted position. The exterior assembly includes a rotatable exterior manual actuator. The interior assembly includes a clutch having a coupling state and a decoupling state. The driving tailpiece is connected between the exterior manual actuator and the clutch. The driven tailpiece is connected between the clutch and the bolt mechanism such that rotation of the driven tailpiece actuates the bolt assembly. In the coupling state, the clutch couples the driving tailpiece with the driven tailpiece such that the exterior manual actuator is operable to actuate the bolt assembly. In the decoupling state, the clutch decouples the driving tailpiece from the driven tailpiece such that the exterior manual actuator is inoperable to actuate the bolt assembly.

  • Patent number: 11168504
    Abstract: An exemplary armature assembly is configured for use with a door closer comprising a pinion, and generally includes a first arm configured for rotational coupling with the pinion, a second arm pivotably coupled to the first arm at a pivot joint, and a hold-open mechanism. The hold-open mechanism generally includes a clutch having a decoupling and a coupling state, and an electromechanical driver operable to transition the clutch between the coupling state and the decoupling state. With the clutch in the decoupling state, a first torque is operable to cause relative pivoting of the arms. With the clutch in the coupling state, the first torque is inoperable to cause relative pivoting of the arms, and a second torque greater than the first torque is operable to cause relative pivoting of the arms.
