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.
