    Das endlose Begrenzerseil 19 wird mittels einer in einer Schachtgrube 20 angeordneten Umlenkrolle 21 gespannt, wobei eine Rollenachse 22 einenends an einem Drehpunkt 23 angelenkt ist und anderenends ein Spanngewicht 24 trägt.The endless governor rope 19 is by means of a in a Well pit 20 arranged deflection pulley 21 tensioned, wherein a roller axle 22 at one end at a pivot point 23rd hinged and the other end carries a tension weight 24.

    Fig. 1 zeigt die beispielsweise zwischen dem obersten Stockwerk und dem zweitobersten Stockwerk mit Aufzugspassagieren steckengebliebene Aufzugskabine 2. Die Fangvorrichtung 16 ist nicht eingerückt. Die Antriebseinheit 6 ist stromlos und mittels einer Bremse der Antriebseinheit 6 gebremst. Die Bremse kann beispielsweise manuell gelüftet werden. Falls die Aufzugskabine 2 zusammen mit den Aufzugspassagieren das Gegengewicht 4 gewichtsmässig überwiegt, bewegt sich die Aufzugskabine 2 bei gelüfteter Bremse nach unten. Die eingeschlossenen Aufzugspassagiere können dann die Aufzugskabine 2 auf dem zweitobersten Stockwerk oder auf einer stockwerknahen Position verlassen. Falls das Gegengewicht 4 die Aufzugskabine 2 zusammen mit den Aufzugspassagieren gewichtsmässig überwiegt, bewegt sich die Aufzugskabine 2 bei gelüfteter Bremse nach oben. Die eingeschlossenen Aufzugspassagiere können dann die Aufzugskabine 2 auf dem obersten Stockwerk oder auf einer stockwerknahen Position verlassen.Fig. 1 shows the example between the top Floor and the second upper floor with Elevator passenger stuck elevator car 2. The Safety catch 16 is not engaged. The Drive unit 6 is de-energized and by means of a brake of Drive unit 6 braked. The brake can, for example be ventilated manually. If the elevator car 2 together with the elevator passengers the counterweight 4 weight predominates, the elevator car 2 moves with the brake released, downwards. The trapped Elevator passengers can then lift the elevator car 2 on the second upper floor or on a floor level Leave position. If the counterweight 4 the Elevator car 2 together with the elevator passengers weight predominates, the elevator car 2 moves with the brake released, upwards. The trapped Elevator passengers can then lift the elevator car 2 on the top floor or on a floor level position leave.

    Falls die Aufzugskabine 2 zusammen mit den Aufzugspassagieren mit dem Gegengewicht 4 im Gleichgewicht ist, bleibt die Aufzugskabine 2 bei gelüfteter Bremse stehen. In diesem Fall muss zur Evakuation der Aufzugspassagiere eine zusätzliche Kraft K auf die Aufzugskabine 2 einwirken. Mit der zusätzlichen Kraft K werden die Reibkräfte der Antriebseinheit 6, der Gegengewichtsführungen und der Aufzugskabinenführungen überwunden und die Aufzugskabine 2 nach unten gezogen. If the elevator car 2 together with the Elevator passenger with counterweight 4 in balance is, the elevator car 2 remains with the brake released stand. In this case, to evacuate the Elevator passengers an additional force K on the Act lift car 2. With the additional force K the frictional forces of the drive unit 6, the Counterweight guides and the elevator car guides overcome and pulled the elevator car 2 down.

    Zur Erzeugung der zusätzlichen Kraft K kann ein Seilzug 25 verwendet werden, der einerseits mit dem Begrenzerseil 19 in Verbindung steht und andererseits in der Schachtgrube 20 verankert ist. Ein Zugseil 26 des Seilzuges 25 ist mittels einer Seilklemme 27 mit dem Begrenzerseil 19 verbunden und mittels eines Ankerseiles 28 mit einem Ankerpunkt 29 der Schachtgrube 20 verbunden. Im Falle von Gewichtsgleichheit zwischen Aufzugskabine 2 zusammen mit den Aufzugspassagieren und dem Gegengewicht 4 löst eine Person die Bremse der Antriebseinheit 6, eine weitere Person steigt in die Schachtgrube 20 und betätigt eine Kurbel 30 des Seilzuges 25, wobei die Aufzugskabine 2 mittels des Seilzuges 25 auf das zweitoberste Stockwerk gezogen wird. Falls sich die Aufzugskabine 2 nach dem Überwinden der Haftreibung selbständig nach unten bewegt, kann die Aufzugskabine mittels der Bremse der Antriebseinheit 6 abgebremst werden. Im Notfall wird das Begrenzerseil 19 blockiert und die Fangvorrichtung 16 eingerückt sobald die Seilklemme 27 an der Rollenachse 22 ansteht.To generate the additional force K, a cable 25 used, on the one hand with the limiter 19th in connection and on the other hand in the shaft pit 20 is anchored. A pull cable 26 of the cable 25 is by means a cable clamp 27 connected to the governor rope 19 and by means of an anchor rope 28 with an anchor point 29 of the Shaft pit 20 connected. In case of equal weight between the elevator car 2 together with the Elevator passenger and the counterweight 4 triggers a person the brake of the drive unit 6, another person climbs into the pit 16 and actuates a crank 30 the cable 25, wherein the elevator car 2 by means of Cable 25 is pulled to the second-highest floor. If the elevator car 2 after overcoming the Stiction independently moves down, the Elevator cabin by means of the brake of the drive unit 6 be slowed down. In an emergency, the governor rope 19 blocked and the safety gear 16 engaged as soon as the Rope clamp 27 is present at the roller axle 22.

    Zur Erzeugung der zusätzlichen Kraft K kann anstelle des Seilzuges 25 ein an der Aufzugskabine 2 angeordnetes Seil oder Band vorgesehen sein, das vorzugsweise in der Schachtgrube 20 verankert ist und im Betriebsfall mit der Aufwärtsbewegung der Aufzugskabine 2 abrollbar und mit der Abwärtsbewegung der Aufzugskabine 2 aufrollbar ist. Im Falle von Gewichtsgleichheit zwischen Aufzugskabine 2 zusammen mit den Aufzugspassagieren und dem Gegengewicht 4 löst eine Person die Bremse der Antriebseinheit 6, eine weitere Person steigt in die Schachtgrube 20 und zieht die Aufzugskabine 2 mittels des Seils oder Bandes auf das zweitoberste Stockwerk. Dieses Vorgehen eignet sich besonders bei kleineren Aufzugsanlagen mit kleineren Aufzugskabinen. Das Seil oder Band kann anstatt an der Aufzugskabine 2 am Gegengewicht 4 angeordnet sein. Die Aufzugskabine 2 wird dann auf das nächsthöhere Stockwerk gezogen.To generate the additional force K, instead of the Cable 25 a arranged on the elevator car 2 rope or band, preferably in the Shaft pit 20 is anchored and in the operating case with the Upward movement of the elevator car 2 unrolled and with the Downward movement of the elevator car 2 is rolled up. in the Case of equal weight between elevator car 2 together with the elevator passengers and the counterweight 4 a person releases the brake of the drive unit 6, a another person climbs into the pit 20 and pulls the Elevator car 2 by means of the rope or tape on the second upper floor. This procedure is suitable especially for smaller elevator systems with smaller ones Elevator cars. The rope or band can instead of at the Elevator car 2 may be arranged on the counterweight 4. The Elevator car 2 will then move to the next floor drawn.

    Fig. 1 zeigt eine maschinenraumlose Aufzugsanlage. Die erfindungsgemässe Einrichtung zur Evakuation von Aufzugspassagieren kann auch auf eine Aufzugsanlage mit Maschinenraum angewendet werden.Fig. 1 shows a machine room-less elevator system. The Inventive device for the evacuation of Elevator passenger can also use an elevator system Engine room to be applied.

    Fig. 2 zeigt den Seilzug 25 in Verbindung mit einem Energiespeicher zum Bewegen einer steckengebliebenen Aufzugskabine 2. Als Energiespeicher ist beispielsweise eine Zugfeder 31 vorgesehen. Andere Energiespeicher wie pneumatische oder hydraulische Kraftspeicher sind auch denkbar. Vor dem Lösen der Bremse der Antriebseinheit 6 wird die Feder 31 mittels des Seilzuges 25 gespannt und danach die Bremse gelöst. Die Federkraft der Zugfeder 31 wirkt mittels des Begrenzerseiles 19 auf die Aufzugskabine 2 ein, bis diese auf dem zweitobersten Stockwerk oder auf einer stockwerknahen Position ankommt.Fig. 2 shows the cable 25 in conjunction with a Energy storage to move a stuck Elevator car 2. As energy storage is, for example a tension spring 31 is provided. Other energy storage like pneumatic or hydraulic power storage are also conceivable. Before releasing the brake of the drive unit 6 the spring 31 is tensioned by means of the cable 25 and then the brake released. The spring force of the tension spring 31 acts by means of the limiter rope 19 on the elevator car 2 until this on the second-highest floor or up a floor-level position arrives.

    Wie in Fig. 3 gezeigt, kann die Zugfeder 31 durch ein Gewicht 32 ersetzt werden. Vor dem Lösen der Bremse wird das Gewicht 32 mittels des Seilzuges 25 angehoben. Nach dem lösen der Bremse zieht das Gewicht 32 die Aufzugskabine 2 nach unten. Das Gewicht 32 kann auch auf dem Boden der Schachtgrube 20 liegen und als Ankerpunkt dienen.As shown in Fig. 3, the tension spring 31 by a Weight 32 replaced. Before releasing the brake is the weight 32 is raised by means of the cable 25. After this releasing the brake pulls the weight 32, the elevator car. 2 downward. The weight 32 can also be on the bottom of the Shaft pit 20 and serve as anchor point.

    Mit den Ausführungsvarianten der Fig. 2 und 3 ist zur Evakuation der Aufzugspassagiere lediglich eine Person notwendig.With the embodiments of Figs. 2 and 3 is for Evacuation of the elevator passengers only one person necessary.
