    Abstract: An automatic door driving system is disclosed, which can electrically perform automatic door opening/closing operation in case of emergency, i.e., occurrence of a fire, or power stoppage and effect automatic door opening/closing control according to the prevailing situation. In the driving system, an AC power source and battery power source are selectively connected through an emergency battery unit to an automatic door controller for controlling an automatic door drive motor. Normally, electric power is supplied from the AC power source to the automatic door controller, while the battery power source is charged from the AC power source. At the time of power stoppage, electric power is supplied from the battery power source to the automatic door controller.

    Abstract: In a door lock comprised of an elongated housing in which a piston loaded with a spring is displaceable in two opposite axial directions, a rotatable locking shaft connected to the door wing and provided with a pinion engaged with a rack formed on that piston, the spring is prestressed in the direction of the closing of the door. The spring acts on a displaceable supporting member which displaces the piston in the housing of the lock. An electromotor actuated by a control unit is operated to displace the supporting member.

    Abstract: An electrically actuated door holder and release for the multipoint holding of a pivoted door throughout a range of door open angles, and for the release of a held door either electrically or in response to manual override. The door holder comprises a channel which pivotally supports through linkages an elongated hold-open bar. An elongated friction strip is carried by the hold-open bar. The hold-open bar is normally held in hold-open position under tension by an armature spring coupled to the holdopen bar. The channel is formed with a slot which guides a slide block which moves linearly along the length of the hold-open bar in response to changes in the angle of door opening. The slide block carries a pivotally supported hold-open cam which engages the friction strip to effect door hold open in the event the armature linkage is further placed under tension by energization of an electromagnet. Upon deenergization of the electromagnet, or alternatively upon the application of a manual override door closing force, the hold-open bar is pivoted away from the slide block and the friction strip engaging cam and the door is released.
