Abstract: An improved latching lever assembly for use in an electromechanical door holder-closer having a closer spring, a dashpot, and an electromagnet. The electromagnet actuates the lever assembly to latch the spring-dashpot combination to effect a desired door hold open position. The lever assembly comprises a lever, a fulcrum at one end of the lever, and an armature located generally at the other end of the lever and electromagnetically coupled to the electromagnet. A latching detent is located on the lever intermediate the fulcrum and armature to latch a camming roller to arrest the spring-dashpot combination when the electromagnet is energized. An armature-lever coupling spring resiliently couples the armature to the lever to enable the lever to pivot about its fulcrum during manual override of the door holder-closer without a corresponding movement of the armature relative the energized electromagnet, thereby eliminating armature release noises.

Abstract: An electrical connector pivot hinge comprising jamb and door hinge portions each having a knuckle. The jamb knuckle is formed with a through bore, and the door knuckle is formed with a partial bore. Both bores are axially aligned. A pivot tube is located within both bores, and a sleeve bearing housed within the jamb knuckle envelopes the portion of the pivot tube located within the jamb knuckle bore to provide relative rotation between the knuckles. An electrical conductor extends through passageways formed in both the jamb and door hinge portions as well as the bores of the knuckles so that the hinge serves the dual functions of both a pivot hinge and an electrical connector.
