Die unteren Zugstangen 27 stehen durch ihre eigene Gewichtskraft auf der Fangvorrichtung 23 auf, während die oberen Zugstangen 25 durch die Kraft je einer Feder 30, welche sich auf einem an der Aufzugskabine 21 fest angeordneten Stützlager 31 abstützt, in einer Ruhelage gehalten werden. Der Zugstangenkäfig 26 hängt an den oberen Zugstangen 25, wird aber gleichzeitig durch je einen Bremshebel 32 und 33 einer auf einem Rahmen 34 der Aufzugskabine 21 aufgebauten Mitnehmerbremse 35 beidseitig umgriffen. Die Mitnehmerbremse 35 setzt sich aus den beiden Bremshebeln 32, 33 mit einem Drehzapfen 36, mindestens einer Bremsfeder 37 und einem Bremsmagnet 38 zusammen.

Der in den Fig. 8 und 9 dargestellte Zugstangenkäfig 26 ist über die obere Gleitverbindung 28 mit den oberen Zugstangen 25 und über die untere Gleitverbindung 29 mit den unteren Zugstangen 27 verbunden. Die oberen Zugstangen 25 werden durch die Kraft der auf dem Stützlager 31 sich abstützenden Feder 30 in einer Ruhelage gehalten. Der Zugstangenkäfig 26 hängt mit der oberen Gleitverbindung 28 an den oberen Zugstangen 25 und wird durch je einen Bremshebel 32, 33 der Mitnehmerbremse 35 auf beiden Seiten umgriffen. Die Bremshebel 32, 33 sind um den Drehzapfen 36 schwenkbar gelagert und werden durch die Kraft der Bremsfeder 37 zusammengedrückt oder durch einen Elektromagneten 38 gelüftet.

In den Fig. 3, 4, 5, 8 und 9 ist eine Vorrichtung zum Auslösen einer Sicherheitseinrichtung dargestellt, welche mit Hilfe einer elektromagnetischen Überwachungseinrichtung arbeitet. In der Ausgangsstellung des Aufzuges ist der Anker des stromlosen Bremsmagnetes 28 eingefahren. Die vorgespannte Bremsfeder 37 bewirkt über die Bremshebel 33, 34, den Zugstangenkäfig 26 und die Mitnehmerplatten 39, 40 eine Anpresskraft auf die Führungsschiene 24. Bei der Inbetriebnahme des Aufzuges wird der Bremsmagnet 28 mit Strom gespeist. Der Anker des Bremsmagnetes 28 fährt aus und spannt über die Bremshebel 33, 34 die Bremsfeder 37 weiter vor. Die Mitnehmerplatten 39, 40 heben sich von der Führungsschiene 24 ab, die Aufzugskabine hat freie Fahrt.

Bei unkontrollierter Fahrt der Aufzugskabine 1 wird der Strom zum Bremsmagnet 28 der Mitnehmerbremse 35 unterbrochen. Die vorgespannte Bremsfeder 37 presst den Zugstangenkäfig 26 über die Mitnehmerplatten 39, 40 an die Führungsschiene 24. Je nach der Fahrtrichtung der Aufzugskabine 1 führt der Zugstangenkäfig 26, durch die an der Führungsschiene 24 festgeklemmten Mitnehmerplatten 39, 40, eine nach oben gerichtete beziehungsweise nach unten gerichtete Relativbewegung aus. Die weiteren Bewegungsabläufe zum Auslösen der Fangvorrichtung 23 oder der Kabinenbremse 22 erfolgen über die Zugstangen 25, 27 in analoger Weise wie bei einer bekannten, nicht dargestellten mechanischen Auslösung über Begrenzer Steuerseil und Hebelwerk.When the elevator car 1 runs uncontrolled, the current to the
Bei der mechanischen wie auch bei der elektromagnetischen Überwachungseinrichtung, müssen, nach dem Auslösen einer der oben beschriebenen Sicherheitseinrichtungen, eingelegte Bremskeile, welche sich zwischen der Führungsschiene und dem Fang- beziehungsweise Bremsgehäuse verklemmt haben, wieder gelöst werden. Zu diesem Zweck muss die Aufzugskabine in die jeweilige Gegenrichtung der Abbremsung gehoben beziehungsweise gesenkt werden, was aus dem Standort der Antriebsmaschine erfolgen kann.In the mechanical as well as in the electromagnetic monitoring device, inserted brake wedges, which have become jammed between the guide rail and the catching or brake housing, have to be released again after the triggering of one of the safety devices described above. For this purpose, the elevator car must be raised or lowered in the opposite direction of the braking, which can be done from the location of the drive machine.
