   Schmilzt   der Kontakt h infolge Funkenbildung fest, so ist gleichzeitig auch das Gestänge a in der Verriegelungsstellung festgestellt und ein Öffnen der Türen vollständig ausgeschlossen, bis der Kontakt wieder in Ordnung gebracht ist und das   Gestänge   wieder ausgerückt werden kann. 



   Beim Ausrücken des Gestänges wird der Betriebsstrom wieder unterbrochen und infolgedessen ist durch die mechanische Schaltung des   Betriebsstromes durch ein Gestänge.   das gleichzeitig die zwangsweise Verriegelung der Türen bewirkt, jede Möglichkeit genommen,

   If the contact h melts as a result of sparking, the linkage a is also locked in the locked position and opening of the doors is completely excluded until the contact is restored and the linkage can be disengaged again.



   When the linkage is disengaged, the operating current is interrupted again and, as a result, the operating current is mechanically switched through a linkage. which at the same time causes the doors to be locked, taking away every possibility

Claims (1)

schaltung des Betriebsstromes erst nach Verriegelung der Türen erfolgt, dadurch gekennzeichnet, dass der Stromschalter (h) für den Betriebsstrom an einem an sich bekannten, allen Schachttüren gemeinsamen Gestänge (a) angeordnet ist, durch das die Schachttüren zwangsweise verriegelt werden, wodurch beim allfälligen Festschmelzen des Stromschalters auch das Gestänge in seiner Verriegelungsstellung festgestent wird und infolgedessen ein Öffnen der Türen bei geschlossenem Betriebsstrom nicht möglich ist. The operating current is only switched after the doors have been locked, characterized in that the current switch (h) for the operating current is arranged on a rod (a) known per se and common to all shaft doors, by means of which the shaft doors are forcibly locked, which means that if they melt of the power switch, the linkage is also fixed in its locked position and, as a result, it is not possible to open the doors when the operating power is closed.
