Description

Vertikal bewegbare Aufzugür Vertikal bewegbare Aufzugtüren, die über endlose Ketten betrieben werden und ein Türausgleichsgewicht haben, sind seit langem bekannt. Das Ausgleichsgewicht ist dabei so abgestimmt, daß die Tür in ihren Endlagen gehalten ist bzw. in ihrer Schließlage mit einem geringen Druck an der Schließkante anliegt. Das Türausgleichsgewicht ist dabei im Mittel um etwa 40 kg schwerer als die Tür. Besteht nun die Möglichkeit, von außen her eine Kraft auf die Tür aufzubringen, dann ist es ohne weiteres möglich, dieses übergewicht zu überwinden und die Tür zu öff- nen, obwohl der Fahrkorb nicht dahintersteht. Dies tritt insbesondere bei Aufzügen auf, bei denen die Tür in ihrer Schließlage frei in den Raum steht und der Schacht nur umwehrt ist. Es ist dann möglich, sich an die Tür anzuhängen und diese zu öffnen. Diese Ausführung ist aus sicherheitstechnischen Gründen nicht zulässig, da sie zu schweren Unfällen führen kann.Vertically Movable Elevator Door Vertically movable elevator doors which are operated via endless chains and have a door counterweight have been known for a long time. The counterweight is adjusted so that the door is held in its end positions or, in its closed position, rests on the closing edge with a slight pressure. The door counterweight is on average around 40 kg heavier than the door. If it is now possible to apply a force to the door from the outside, then it is easily possible to overcome this excess weight and open the door, although the car is not behind it. This occurs in particular in elevators in which the door in its closed position stands freely in the room and the shaft is only fenced. It is then possible to hang onto the door and open it. This version is not permitted for safety reasons, as it can lead to serious accidents.

Um diesen schwerwiegenden Nachteil auszuschalten, mußten derartige Türen wie bei allen Aufzugtüren bisher zusätzlich mit einer Türverriegelung ausgerüstet werden. Diese Türverriegelungen sind komplizierte und damit aufwendige Geräte, die aus diesem Grund auch eine gewisse Störanfälligkeit aufweisen.In order to eliminate this serious disadvantage, such had to be As with all elevator doors, doors have also been equipped with a door lock so far will. These door locks are complicated and therefore expensive devices that for this reason also have a certain susceptibility to failure.

Dieser Nachteil kann erfindungsgemäß auf einfache Weise dadurch vermieden werden, daß zwischen die Ketten und die Tür Stützpendel eingeschaltet sind, die sich nach geringem überschreiten der oberen Totpunktlagge gegen Anschläge legen, wodurch sie die Tür in ihrer oberen Endlage verriegeln.According to the invention, this disadvantage can thereby be avoided in a simple manner be that between the chains and the door support pendulums are switched on after slightly exceeding the top dead center position against stops, thereby locking the door in its upper end position.

Zwar sind Stützpendel von den sogenannten Stützketten-Aufzügen her bekannt. Sie erfüllen dort aber eine ganz andere Funktion, da sie nur die Endlagen des Fahrkorbes begrenzen.Support pendulums are from the so-called support chain lifts known. But they fulfill a completely different function there, since they only have the end positions of the car.

Die Fig. 1 und 2 zeigen eine erfmdungsgemäße Ausführung in den beiden Endlagen. In Fig. 1 sitzt die Tür 1 in ihrer Öffnungslage auf den Anschlägen 2 auf. Die an ihr angelegten Stützpendel 3 sind mit ihren anderen Enden beweglich mit den Ketten 4 verbunden. Diese laufen über Kettenräder 5 und haben an der Gegenseite Ausgleichsgewichte 6 befestigt. An den Angriffspunkten der Ausgleichsgewichte sind Mitnehmer 7 angebaut, mittels deren der nicht gezeichnete Fahrkorb die Bewegung der Tür bewirkt, d. h., der in Ausladestellung einfahrende Fahrkorb zieht über diese Mitnehmer bei seiner Aufwärtsbewegung die Tür nach unten und öffnet sie damit. In Fig. 2 ist die Tür 1 in Schließstellung. Die Stützpendel 3 haben sich gegen die Anschläge 8 gelegt, so daß ein Herunterdrücken der Tür nicht möglich ist. 1 and 2 show an embodiment according to the invention in the two end positions. In Fig. 1, the door 1 is sitting on in its open position on the stops. 2 The support pendulums 3 placed on it are movably connected to the chains 4 at their other ends. These run over chain wheels 5 and have counterweights 6 attached to the opposite side. At the points of application of the counterweights, drivers 7 are built, by means of which the car, not shown, causes the door to move, d. In other words, the car moving into the unloading position pulls the door downwards via these carriers during its upward movement and thus opens it. In Fig. 2 the door 1 is in the closed position. The support pendulums 3 have placed themselves against the stops 8 , so that it is not possible to press the door down.
