Abstract (en)

The emergency unlocking device has an unlocking slide bar (11) to act on the locking lever (4) as it is taken into a guide (12) on the inside (2.1) of the shaft doors (2). The guide covers a breakthrough in the shaft doors for the insertion of a tool to operate the unlocking slide bar so that fire cannot spread to the shaft.

Abstract (de)

Bei dieser Notentriegelungsvorrichtung wird ein Verriegelungshebel (4) mittels eines Entriegelungsschiebers (11) betätigt, der in einer an der Innenseite (2.1) der Schachttüre (2) befestigten Führung (12) geführt wird. Die Führung (12) deckt einen in der Schachttüre (2) angebrachten Durchbruch für die Einführung eines Werkzeuges zur Betätigung des Entriegelungsschiebers (11) ab, so dass bei einem Brand das Feuer nicht auf den Aufzugsschacht übergreifen kann. <IMAGE>
