Abstract (en)

The electronic control with at least one accumulator and at least one micro-processor releases sensor signals via a cog wheel on a driven shaft which is connected by connecting rods and operating arm to the revolving door. Between the driven shaft and the connecting rods or operating arm is a gear changing its transmission ratio by means of the swing angle of the revolving door. The gear has two inter-engaging cog wheels (8,13) each formed by a circular gear rim and mounted eccentrically in relation to their center points (16,17). The first cog wheel operates in conjunction with a driven shaft, and the second cog wheel operates coaxially in relation to its rotary point (18) with the driven cog wheel. The rotary axis of the driven shaft runs through the rotary point (15) of the first cog wheel.

Abstract (de)

Die Erfindung betrifft einen Drehtürantrieb mit einer elektromechanischen oder elektrohydraulischen Antriebsvorrichtung, die für das Öffnen und Schließen eines angeschlossenen Drehflügels das nötige Öffnungs- und Schließmoment liefert, wobei eine elektronische Regelung/Steuerung mit mindestens einem Speicher und mindestens einem Mikroprozessor aufgrund von Sensorsignalen das Öffnungs- bzw.- Schließmoment über ein auf einer Abtriebswelle angeordnetes Zahnrad abgibt, die über ein Gestänge und einen Betätigungsarm mit dem Drehflügel verbunden ist, wobei zwischen der Abtriebswelle des Drehflügelantriebes und dem Gestänge bzw. dem Betätigungsarm eine Vorrichtung 2 vorhanden ist, die einer Veränderung des Öffnungs- und Schließmomentes über den Drehwinkel des Drehflügels bewirkt. <IMAGE>
