Abstract (en)

The building door actuator (3) has a drive motor (31) to close the door and an energy reservoir coil spring to open the door. The reservoir (34) is primed as the door is closed and some of the energy is reused to open the door. The reservoir has an emergency opening control with an electrically operated lock (33) to retain the door closed. The lock can be released by an electrical signal so that the door can be opened. Claims include a method for operating the door

Abstract (de)

Es wird eine Antriebseinrichtung (1) mit Notöffnungsvorrichtung für eine Tür mit Drehflügel (2) beschrieben. Bekannte Antriebseinrichtungen verwenden zur Notöffnung mechanische Kupplungen welche automatisch oder manuell ausgelöst werden müssen. Die neue Antriebseinrichtung (1) soll einfacher aufgebaut sein und automatisch arbeiten. Das Öffnen des Drehflügels (2) erfolgt selbsttätig über einen Energiespeicher (34) und das Schließen motorisch unter Fremdenergiezufuhr, wobei der Energiespeicher (34) geladen wird. Zum Halten des Drehflügels ist eine elektrisch schaltbare Haltevorrichtung (33) vorgesehen, die von einer Steuervorrichtung (5) ausgelöst wird. Im Notfall öffnet sich der Drehflügel (2) selbsttätig unter Wirkung des Energiespeichers (34). <IMAGE>
