Die Erfindung betrifft eine Sicherheitseinrichtung für einen Aufzug mit einer in einem Aufzugsschacht verfahrbaren Aufzugskabine und einem im Aufzugsschacht verfahrbaren Gegengewicht, wobei ein die Geschwindigkeit der Aufzugskabine bzw. des Gegengewichtes überwachender Geschwindigkeitsbegrenzer vorgesehen ist, der bei Übergeschwindigkeit ein die Aufzugskabine bzw. das Gegengewicht stillsetzende Fangvorrichtung betätigt.The invention relates to a safety device for an elevator with an elevator car movable in an elevator car and a counterweight movable in the elevator shaft, wherein a speed of the elevator car or the counterweight monitoring speed limiter is provided which operates at overspeed the elevator car or the counterweight shutdown catcher ,

Aus der Schrift US 1 803 762 ist eine Einrichtung zum Auslösung einer an einer Aufzugskabine angeordneten Fangvorrichtung mit Fangkeilen bekannt geworden. Ein Begrenzerseil eines die Geschwindigkeit der Aufzugskabine überwachenden Geschwindigkeitsbegrenzers steht in Verbindung mit dem Auslösemechanismus. Ein am Tragrahmen der Aufzugskabine angeordneter vertikaler Ausleger dient als Träger für ein Joch, an dem die Fangvorrichtung mit dem Auslösemechanismus und ein Puffer angeordnet sind. Zwischen Ausleger und Joch ist eine Druckfeder vorgesehen, die eine Einfederung des Jochs im Bremsfall oder beim Auftreffen des Puffers auf dem Prellbock ermöglicht.From the Scriptures US 1 803 762 a device for triggering a arranged on an elevator car safety gear with catch wedges has become known. A governor rope of a speed limiter monitoring the speed of the elevator car is in communication with the triggering mechanism. An arranged on the support frame of the elevator car vertical arm serves as a support for a yoke on which the safety gear with the trigger mechanism and a buffer are arranged. Between boom and yoke, a compression spring is provided which allows deflection of the yoke in case of braking or when hitting the buffer on the buffer.

Ein Nachteil der bekannten Einrichtung liegt darin, dass mit dem vertikalen Ausleger eine grosse Schachtgrubentiefe notwendig ist.A disadvantage of the known device is that with the vertical boom a large shaft pit depth is necessary.

Aus der Anmeldeschrift EP 0 432 634 A2 ist eine für den Notfall vorgesehene Fangvorrichtung zum Festhalten einer Aufzugskabine an Führungsschienen bekannt geworden. Je Schienenseite ist ein in einem Gehäuse angeordneter Fangkeil vorgesehen. Bei Übergeschwindigkeit der Aufzugskabine verkeilen sich die gegenläufig wirkenden Fangkeile zwischen der Führungsschiene und dem Gehäuse. Das Gehäuse ist mittels Bolzen und Federn seitlich verschiebbar mit der Aufzugskabine verbunden. Mit der seitlichen Verschiebbarkeit des Gehäuses haben Abweichungen der Führungsschiene aus der Lotrechten keine Wirkung auf die Aufzugskabine.From the registration EP 0 432 634 A2 is one for the Emergency provided catching device for holding an elevator car to guide rails become known. Each rail side a arranged in a housing catching wedge is provided. At overspeed of the elevator car, the counter-acting catch wedges wedged between the guide rail and the housing. The housing is connected by means of bolts and springs laterally displaceable with the elevator car. With the lateral displacement of the housing deviations of the guide rail from the vertical have no effect on the elevator car.

Hier will die Erfindung Abhilfe schaffen. Die Erfindung, wie sie in Anspruch 1 gekennzeichnet ist, löst die Aufgabe, die Nachteile der bekannten Einrichtung zu vermeiden und eine Einrichtung zu schaffen, mittels der der Fahrkomfort der Aufzugspassagiere im Notfall verbessert wird.The invention aims to remedy this situation. The invention, as characterized in claim 1 solves the problem of avoiding the disadvantages of the known device and to provide a device by means of the ride comfort of the elevator passengers is improved in an emergency.

Die durch die Erfindung erreichten Vorteile sind im wesentlichen darin zu sehen, dass die Sicherheit und der Fahrkomfort der Aufzugspassagiere im Notfall wesentlich verbessert werden kann. Im Auslösefall der Fangvorrichtung werden die Aufzugspassagiere weniger grossen Verzögerungskräften ausgesetzt, was das Unfallrisiko erheblich vermindert. Ausserdem wird die erfindungsgemässe Einrichtung der Norm gerecht, die verlangt, dass die Ausfederungsgeschwindigkeit kleiner sein muss als die Einfederungsgeschwindigkeit. Weiter vorteilhaft ist, dass das Pufferelement einfach austauschbar ist und dass Mehrwegpuffer oder Einwegpuffer eingesetzt werden können. Weiter vorteilhaft ist, dass mit der Verwendung eines Pufferelementes eine Sperrfangvorrichtung auch bei Aufzugsanlagen mit höheren Geschwindigkeitslimiten als für die Sperrfangvorrichtung vorgesehen eingesetzt werden kann. Beispielsweise ist eine Sperrfangvorrichtung zulässig bis 0,63 m/s. Mit dem Pufferelement ist dieselbe Sperrfangvorrichtung zulässig bis 1 m/s.The advantages achieved by the invention are essentially to be seen in the fact that the safety and comfort of the elevator passengers in an emergency can be substantially improved. In case of triggering the safety gear, the elevator passengers are exposed to less large deceleration forces, which significantly reduces the risk of accidents. Moreover, the device according to the invention does justice to the standard which requires that the rebound speed must be less than the compression speed. It is also advantageous that the buffer element is easily replaceable and that reusable buffers or disposable buffers can be used. It is also advantageous that with the use of a buffer element, a safety catch device can also be used in elevator systems with higher speed limits than provided for the safety catch device. For example, a safety catch is allowed up to 0.63 m / s. With the buffer element the same safety catch is allowed up to 1 m / s.

Fig. 1 zeigt einen Aufzug mit einer in einem Aufzugsschacht 1 verfahrbaren Aufzugskabine 2, die über ein Seil 3 mit einem Gegengewicht 4 verbunden ist. Das Seil 3 wird im Betriebsfall mittels einer Treibscheibe 5 einer Antriebseinheit 6 angetrieben. Aufzugskabine 2 und Gegengewicht 4 werden mittels sich über die Schachthöhe erstreckender Führungsschienen 7 geführt. Die Aufzugsanlage weist ein oberstes Stockwerk mit einer obersten Stockwerktür 8, ein zweitoberstes Stockwerk mit einer zweitobersten Stockwerktür 9, weitere Stockwerke mit weiteren Stockwerktüren 10 und ein unterstes Stockwerk mit einer untersten Stockwerktür 11 auf. In einem Schachtkopf 12 ist die Antriebseinheit 6 und ein Geschwindigkeitsbegrenzer 13 angeordnet, der die Geschwindigkeit der Aufzugskabine 2 überwacht und bei Übergeschwindigkeit die Aufzugskabine 2 stillsetzt. Je Seite der Aufzugskabine 2 ist ein Doppelhebel 14,14.1 vorgesehen, der an einem Drehpunkt 15,15.1 angelenkt ist. Eine zur Stillsetzung der Aufzugskabine 2 vorgesehene und an einem unteren Joch 2.1 der Aufzugskabine 2 angeordnete Fangvorrichtung 16,16.1 ist mittels eines ersten Gestänges 17,17.1 mit der einen Seite des Doppelhebels 14,14.1 verbunden, wobei die eine Seite des ersten Doppelhebels 14 mit einem Begrenzerseil 19 des Geschwindigkeitsbegrenzers 13 verbunden ist. Die andere Seite des ersten Doppelhebels 14 ist mittels eines zweiten Gestänges 18 mit dem zweiten Doppelhebel 14.1 verbunden. Wird die eine Seite des ersten Doppelhebels 14 nach oben bewegt, so wird die Fangvorrichtung 16,16.1 eingerückt, wobei sich mit der Führungsschiene 7 verkeilende Sperrelemente die Aufzugskabine 2 im Notfall stillsetzen. Bei Normalbetrieb treibt die Aufzugskabine 2 das Begrenzerseil 19 mittels des ersten Doppelhebels 14 an. Bei Übergeschwindigkeit der Aufzugskabine 2 blockiert der Geschwindigkeitsbegrenzer 13 das Begrenzerseil 19. Dadurch wird der erste Doppelhebel 14 nach oben ausgelenkt und der zweite Doppelhebel 14.1 betätigt, wobei die Fangvorrichtung 16,16.1 beidseitig der Aufzugskabine 2 eingerückt wird. Fig. 1 shows an elevator with a movable in an elevator shaft 1 elevator car 2, which is connected via a cable 3 with a counterweight 4. The cable 3 is driven in the case of operation by means of a traction sheave 5 of a drive unit 6. Elevator car 2 and counterweight 4 are guided by extending over the shaft height guide rails 7. The elevator installation has a top floor with a top floor door 8, a second upper floor with a second upper floor door 9, further floors with further floor doors 10 and a bottom floor with a lowermost floor door 11. In a shaft head 12, the drive unit 6 and a speed limiter 13 is arranged, which monitors the speed of the elevator car 2 and stops the elevator car 2 at overspeed. Per side of the elevator car 2, a double lever 14,14.1 is provided which is articulated at a pivot point 15,15.1. A provided for stopping the elevator car 2 and arranged on a lower yoke 2.1 of the elevator car 2 safety gear 16,16.1 is connected by means of a first linkage 17,17.1 with one side of the double lever 14,14.1, wherein one side of the first double lever 14 with a Limiter rope 19 of the speed limiter 13 is connected. The other side of the first double lever 14 is connected by means of a second linkage 18 with the second double lever 14.1. If one side of the first double lever 14 is moved upward, then the catching device 16, 16. 1 is engaged, locking elements wedging with the guide rail 7 stopping the elevator car 2 in an emergency. In normal operation the elevator car 2 drives the governor rope 19 by means of the first double lever 14. If the elevator car 2 is overspeed, the speed limiter 13 blocks the governor rope 19. As a result, the first double lever 14 is deflected upwards and the second double lever 14.1 is actuated, the safety gear 16,16.1 being engaged on both sides of the elevator car 2.

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 tensioned by means disposed in a shaft pit 20 guide roller 21, wherein a roller axle 22 is hinged at one end at a pivot point 23 and the other end carries a tension weight 24.

Fig. 2 zeigt die auf Bild 1 gezeigte linke Fangvorrichtung 16.1 mit Puffer 30. Das untere Joch 2.1 der Aufzugskabine 2 weist einen Ausleger 31 auf, an dem ein Schlitten 32 verschiebbar angeordnet ist. Der Schlitten 32 ist beidseitig entlang von am Ausleger 31 angeordneten Linearführungen 33 beispielsweise mittels Bolzen 34 geführt. Im Auslösefall in Abwärtsrichtung der Fangvorrichtung 16.1 führt der Schlitten 32 eine mit einem Pfeil P1 symbolisierte vertikale, bzw. eine in Längsrichtung der Führungsschiene 7 verlaufende Bewegung aus. Die sich am Führungsschenkel der Führungsschiene 7 festsetzende Fangvorrichtung 16.1 bewirkt als ganzes die Bewegung P1. Dabei federt der zwischen Schlitten 32 und einem Anschlag 35 des unteren Jochs 2.1 angeordnete Puffer 30 ein. Nach dem Stillstand der Aufzugskabine 2 federt der Puffer 30 wieder aus, wobei der Puffer 30 so aufgebaut und bemessen ist, dass die Ausfederungsgeschwindigkeit kleiner ist als die Einfederungsgeschwindigkeit. Üblicherweise werden Mehrwegpuffer aus beispielsweise zelligem Polyurethan verwendet. Einwegpuffer sind auch möglich. Fig. 2 shows the left-hand safety gear 16.1 shown in Figure 1 with buffer 30. The lower yoke 2.1 of the elevator car 2 has a boom 31 on which a carriage 32 is slidably mounted. The carriage 32 is guided on both sides along linear guides 33 arranged on the arm 31, for example by means of bolts 34. When triggered in the downward direction of the safety gear 16.1, the carriage 32 performs a symbolized by an arrow P1 vertical, or extending in the longitudinal direction of the guide rail 7 movement. The catching device 16.1 which settles on the guide leg of the guide rail 7 as a whole effects the movement P1. In this case, the buffer 30 arranged between the carriage 32 and a stop 35 of the lower yoke 2.1 springs. After the elevator car 2 has come to a standstill, the buffer 30 springs back out, the buffer 30 being constructed and dimensioned such that the rebound speed is less than the compression speed. Usually reusable buffers are used, for example, cellular polyurethane. Disposable buffers are also possible.

Am Ausleger 31 ist auch ein Führungsschuh 36 angeordnet, der vom nicht dargestellten Führungsschenkel der Führungsschiene 7 geführt ist.On the boom 31 and a guide shoe 36 is arranged, which is guided by the guide leg of the guide rail 7, not shown.

Die auf Bild 1 gezeigte rechte Fangvorrichtung 16 mit Puffer 30 und Ausleger 31 ist sinngemäss aufgebaut.The right-hand catching device 16 shown in FIG. 1 with buffer 30 and extension arm 31 is constructed analogously.

Die Fangvorrichtung 16,16.1 mit Puffer und Ausleger kann auch am Gegengewicht 4 angeordnet sein.The safety gear 16,16.1 with buffer and boom can also be arranged on the counterweight 4.

Der Puffers 30 weist eine Rücklaufdämpfung auf, die bewirkt, dass die Ausfederungsgeschwindigkeit kleiner ist als die Einfederungsgeschwindigkeit. Beispielsweise kann ein Puffermaterial verwendet werden, das aus einem zelligen Polyurethan besteht. Der Dämpfungseffekt entsteht weitgehend durch die Energieaufnahme der sich erwärmenden Luft in den Polyurethanzellen. Ausserdem wird dieser Dämpfungseffekt unterstützt durch innere Reibung des Polyurethanmaterials und Verdrängung der Luftblasen im Material durch die porösen Zellwandungen.The buffer 30 has a return loss that causes the rebound speed to be less than the jounce speed. For example, a buffer material consisting of a cellular polyurethane can be used. The damping effect is largely due to the energy consumption of the warming air in the polyurethane cells. In addition, this damping effect is supported by internal friction of the polyurethane material and displacement of the air bubbles in the material through the porous cell walls.

Prinzipiell kann die erfindungsgemässe Einrichtung auch für den Fang nach oben verwendet werden. In dieser Anwendung ist die Fangvorrichtung oben und der Puffer unten angeordnet.In principle, the device according to the invention can also be used for catching upwards. In this application, the safety gear is at the top and the buffer at the bottom.
