Der Erfindung liegt die Aufgabe zugrunde, eine gegenüber der vorstehend beschriebenen einfachere Entriegelungsvorrichtung vorzuschlagen.The invention is based on the object, a relation to the previously described simpler unlocking device propose.
Diese Aufgabe wird durch die im Patentanspruch 1 angegebene
Erfindung gelöst. Hierbei steht der Verriegelungshebel über
einen Entriegelungsschieber mit einer Betätigungseinrichtung
in Wirkverbindung. Der Entriegelungsschieber besteht
lediglich aus einem Stück und wird unmittelbar von einem
Trägerblech gehalten und geführt. Die Betätigungseinrichtung
weist ein am Trägerblech drehbar gelagertes Betätigungsglied
auf, das mit einer Spindel drehfest verbunden ist, die mit
einem nicht-selbsthemmenden Steilgewinde versehen ist. Auf
der Spindel ist eine Spindelmutter geführt, an welcher der
Entriegelungsschieber befestigt ist.This object is achieved by the specified in
Die mit der Erfindung erzielten Vorteile sind darin zu sehen, dass der Entriegelungsschieber nur aus einem Stück besteht und zu seiner Führung und Halterung keine zusätzlichen Teile benötigt werden, wohingegen beim Stand der Technik mehrere Teile für die Verbindung zwischen dem Hakenriegel und dem Betätigungselement erforderlich sind. Ein weiterer Vorteil besteht darin, dass für die Rückstellung keine Feder verwendet wird. Damit wird die Bruchgefahr, wie sie für die im genannten Stand der Technik verwendete Zugfeder mit angebogenen Oesen besteht, vermieden und die Betriebssicherheit verbessert. Mit den vorgeschlagenen Massnahmen kann daher eine kostengünstige, sichere und platzsparende Lösung realisiert werden.The advantages achieved by the invention are to see that the release slide is only one piece exists and none of its leadership and support additional parts are needed, whereas in the state the technique of multiple parts for the connection between the Hook latch and the actuator are required. Another advantage is that for the Reset no spring is used. This will be the Danger of breakage, as mentioned for the mentioned in the prior art used tension spring with curved eyelets is avoided and improved operational safety. With the proposed measures can therefore be a cost-effective, safe and space-saving solution can be realized.

In den Fig.1 bis 3 ist mit 1 ein mit dem Türrahmen einer
Schachttür verbundenes Trägerblech bezeichnet, an dem ein
Verriegelungsglied 2 befestigt ist. Ein Verriegelungshebel 3
ist um eine Achse 4 drehbar an einem nicht weiter
dargestellten Hängewagen der Schachttür gelagert. Der
Verriegelungshebel 3 in Form eines Doppelhebels, weist an
dem einen Hebelarm 5 einen Haken 6 auf, während an dem
anderen Hebelarm 7 ein Gewicht 8 befestigt ist. In
verriegeltem Zustand ist unter dem Einfluss des Gewichtes 8
der eine Hebelarm 5 angehoben und der Haken 6 mit dem
Verriegelungsglied 2 im Eingriff.1 to 3 with the door frame of a
Shaft door connected carrier plate indicates at the one
Locking member 2 is attached. A
Am anderen Hebelarm 7 des Verriegelungshebels 3 ist ein
Bolzen 9 befestigt. Unterhalb des Bolzens 9 ist ein
Entriegelungsschieber 10 angeordnet, der verschiebbar am
Trägerblech 1 anliegend geführt und gehalten wird. Zu diesem
Zweck ist im Trägerblech 1 ein Ausschnitt 11 vorgesehen und
das Trägerblech 1 auf der Höhe des Ausschnittes 11 durch
zweimaliges Abbiegen in stumpfen Winkeln derart verformt,
dass der Entriegelungsschieber 10 erst an der einen Seite
des Trägerbleches 1 und dann an dessen anderer Seite geführt
wird. Ein unteres Teil 10.1 des Entriegelungsschiebers 10
ist breiter als ein oberes Teil 10.2 des
Entriegelungsschiebers 10, wobei an den oberen Ecken des
unteren Teiles 10.1 und am oberen Teil 10.2
reibungsvermindernde Beläge 12, 13, 14 vorgesehen sind. Der
Entriegelungsschieber 10 ist an seinem unteren Ende mit
einer Betätigungseinrichtung 20 verbunden.At the
Die Betätigungseinrichtung 20 weist ein mit einem Dreikant
versehenes Betätigungsglied 21 auf, das in einer am
Trägerblech 1 befestigten Lagerplatte 22 drehbar gelagert
ist. Das Betätigungsglied 21 ist mit einer Spindel 23
drehfest verbunden, die mit einem ein- oder mehrgängigen -
vorzugsweise zweigängigen - nicht-selbsthemmenden
Steilgewinde, beispielsweise Trapezgewinde, versehen ist.
Eine auf der Spindel 23 sitzende Spindelmutter 24 ist mit
dem Entriegelungsschieber 10 verschraubt, so dass beim
Drehen des Betätigungsgliedes 21 mittels eines
Dreikantschlüssels der Entriegelungsschieber 10 nach oben
gegen den Bolzen 9 geschoben, der Verriegelungshebel 3
geschwenkt und die Schachttür entriegelt wird. Beim
Verriegelungsvorgang wird die Abwärtsbewegung des
Entriegelungsschiebers 10 durch das Gewicht 8 des
Verriegelungshebels 3 eingeleitet und durch die reibungarme
Gestaltung des Entriegelungsschiebers 10 und der
Betätigungseinrichtung 20 unterstützt, bis die Spindel 23,
bzw. der Entriegelungsschieber 10, wieder die
Ausgangsstellung erreicht hat.The
