  • Patent number: 11661782
    Abstract: An exemplary armature assembly is configured for use with a door control mounted to one of a door or a doorframe. The door control includes a rotatable pinion, and the armature assembly includes an armature, a shoe, and an elastic component. The armature has a first end and an opposite second end, and the first end includes an opening sized and shaped to receive the pinion at a first interface. The shoe is configured for mounting to the other of the door or the doorframe, and the second end of the armature is pivotally connected to the shoe at a second interface. In certain forms, the elastic component coupled with the armature and configured to absorb mechanical shocks at one of the first interface or the second interface. In certain forms, the elastic component is configured to absorb mechanical shocks along the length of the armature.

  • 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.
