Abstract

In a lifting device (1) for raising and lowering loads, especially in the stage and studio sector, the lifting force is generated by a pneumatic concertina (2). Guides (61, 62) for guiding a vertically raisable and lowerable lifting platform (7) are arranged on a baseplate (6), the concertina being fastened between the base plate and lifting platform. The concertina has the form of two truncated cones (201, 202) which are connected to one another by their small base circles (203, 204) and are connected respectively to the baseplate and to the lifting platform by their large base circles (205, 206). <IMAGE>

Description

Die Erfindung betrifft eine Hubvorrichtung zum Heben und Senken von Lasten, insbesondere im Bereich der Bühnen-und Studiotechnik, bei der die Hebekraft durch einen pneumatischen Balg erzeugt wird.The invention relates to a lifting device for lifting and lowering loads, particularly in the area of stage and studio technology, in which the lifting force is generated by a pneumatic bellows.

Es ist bekannt, die Kraft aufgepumpter Bälge zum Heben und Senken von Lasten zu verwenden. Da es möglich ist, durch die Wahl entsprechend großer Bälge sehr große Hebekräfte zu erzeugen, genügen verhältnismäßig geringe Drücke, um diese Bälge aufzublasen. Ein Nachteil aller bekannten Balgkonstruktionen ist darin zu sehen, daß der Balg sich in unkontrollierter Weise zusammenlegt, wenn die Druckluft abgelassen wird, wofür eine größere Grundfläche benötigt wird, die nicht immer vorhanden ist. Hierdurch ist das Einsatzgebiet der Hubbälge in mancher Hinsicht begrenzt.It is known to use the force of inflated bellows to lift and lower loads. Since it is possible to generate very large lifting forces by selecting appropriately large bellows, relatively low pressures are sufficient to inflate these bellows. A disadvantage of all known bellows designs is that the bellows collapses in an uncontrolled manner when the compressed air is released, which requires a larger footprint, which is not always available. This limits the area of application of the bellows in some respects.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Hubvorrichtung mit einem pneumatischen Balg zu entwikkeln, bei der sich der Balg automatisch so zusammenlegt, daß er keine größere Fläche als die Hubplattform selbst benötigt. Diese Aufgabe wird nach der Erfindung so gelöst, daß an einer Grundplatte Führungen zur Führung einer in senkrechter Richtung heb- und senkbaren Hubplattenform angeordnet sind, und daß zwischen Grundplatte und Hubplattform der Balg befestigt ist, der die Form zweier Kegelstümpfe aufweist, die mit ihren kleinen Grundkreisen miteinander und mit ihren größeren Grundkreisen jeweils mit der Grundplatte und der Hubplattform verbunden sind. Diese Balgkonstruktion hat den Vorteil, daß sich der Balg beim Absenken der Hubplattform unter dieser zusammenlegt, so daß die Hubplattform auch unter räumlich beengten Verhältnissen eingesetzt werden kann.The invention is therefore based on the object of developing a lifting device with a pneumatic bellows in which the bellows automatically folds up so that it does not require a larger area than the lifting platform itself. This object is achieved according to the invention in such a way that guides for guiding a lifting plate shape which can be raised and lowered in the vertical direction are arranged on a base plate, and that the bellows is fastened between the base plate and lifting platform and has the shape of two truncated cones, with their small ones Base circles are connected to each other and with their larger base circles to the base plate and the lifting platform. This bellows construction has the advantage that the bellows collapses under the lifting platform when it is lowered, so that the lifting platform can also be used in confined spaces.

In Figur 1 ist die Seitenansicht einer Hubvorrichtung 1 zum Heben und'Senken von Lasten wiedergegeben. Derartige Hubvorrichtungen haben zahlreiche Anwendungsmöglichkeiten, so z. B. auch in der Bühnen- und Studiotechnik. Bei der Hubvorrichtung 1 wird die Hebekraft durch einen pneumatischen Balg 2 erzeugt, der über eine Leitung 3 mit einem Druckluftgebläse 4 und einem Ventil 5 verbunden ist. An einer Grundplatte 6 sind Führungen 61, 62, 63, 64 zur Führung einer in senkrechter Richtung heb-und senkbaren Hubplattform 7 angeordnet. Der Balg 2 hat die Form zweier Kegelstümpfe 201, 202, die mit ihren kleinen Grundkreisen 205, 206 jeweils mit der Grundplatte 6 und der Hubplattform 7 verbunden ist. Dadurch, daß der Balg 2 aus zwei mit ihren kleinen Grundkreisen 203, 204 miteinander verbundenen Balgteilen besteht, ergibt sich, daß sich beim Auslassen der Luft der Balg 2 zwischen Grundplatte 6 und Hubplattform 7 so zusammenlegt, wie dieses in Figur 1 gezeigt ist.FIG. 1 shows the side view of a lifting device 1 for lifting and lowering loads. Such lifting devices have numerous applications, such as. B. also in stage and studio technology. In the lifting device 1, the lifting force is by a generated pneumatic bellows 2, which is connected via a line 3 to a compressed air blower 4 and a valve 5. Guides 61, 62, 63, 64 for guiding a lifting platform 7 which can be raised and lowered in the vertical direction are arranged on a base plate 6. The bellows 2 has the shape of two truncated cones 201, 202, which are each connected to the base plate 6 and the lifting platform 7 with their small base circles 205, 206. The fact that the bellows 2 consists of two bellows parts connected with their small base circles 203, 204 results in that when the air is let out, the bellows 2 collapses between the base plate 6 and the lifting platform 7 as shown in FIG. 1.

Wenn eine größere Fläche 71 angehoben oder abgesenkt werden soll, so wie dieses in Figur 4 gezeigt ist, dann können mehrere Bälge 21, 22, 23, 24, 25 nebeneinander angeordnet werden. In diesem Fall sind auch mehrere Führungen 61, 62, 63 ... möglich, durch die die Hubplattform 71 immer parallel zur Grundplatte gehalten wird. Es versteht sich, daß die Bälge 21, 22, 23 ... nicht nur, wie in Figur 4 dargestellt ist, in einer Reihe angeordnet sein können, sondern es ist auch möglich, sie flächig anzuordnen und hiermit eine Hubplattform jeder beliebigen Flächenform anzuheben.If a larger surface 71 is to be raised or lowered, as is shown in FIG. 4, then a plurality of bellows 21, 22, 23, 24, 25 can be arranged side by side. In this case, several guides 61, 62, 63 ... are also possible, by means of which the lifting platform 71 is always held parallel to the base plate. It goes without saying that the bellows 21, 22, 23 ... not only can be arranged in a row, as shown in FIG. 4, but it is also possible to arrange them flatly and thereby lift a lifting platform of any surface shape.

Andererseits kann die Aufgabe bestehen, eine Hubplattform auf eine größere Höhe anzuheben, als dieses mit dem Hub eines Balges möglich ist. In diesem Falle können, wie in Figur 5 in Seitenansicht gezeigt ist, mehrere Bälge 21, 22 und 23 übereinandergesetzt werden, wobei jede gewünschte Höhe erreicht werden kann, die durch die Führungen 85, 86 erreichbar ist. Zwischen jeweils zwei Bälgen, z. B. den Bälgen 21 und 22, befindet sich eine dünne Zwischenplatte 81, 82, 83. Auch die dünnen Zwischenplatten 81, 82, 83 ... werden in den Führungen 85, 86 geführt, um hierdurch eine ausreichende Stabilität der übereinander angeordneten Bälge 21, 22, 23 sicherzustellen.On the other hand, the task can be to raise a lifting platform to a greater height than is possible with the lifting of a bellows. In this case, as shown in FIG. 5 in a side view, a plurality of bellows 21, 22 and 23 can be placed one above the other, whereby any desired height that can be reached by the guides 85, 86 can be achieved. Between two bellows, e.g. B. the bellows 21 and 22 is located a thin intermediate plate 81, 82, 83. The thin intermediate plates 81, 82, 83 ... are also guided in the guides 85, 86 in order to ensure sufficient stability of the bellows 21, 22, 23 arranged one above the other.

In Figur 5 sind zwei Arten der Führungen wiedergegeben: Die Führung 85 ist eine Teleskopführung, die sich in einer Grundhülse 851 zusammenschieben läßt. Hierbei ist es möglich, die Grundhülse 851 im Unterflur anzuordnen. Die zweite Art der Führungen ist eine starre Führur:[s-säule 86, die sich nicht zusammenschieben läßt und an der die Hubplattform 7 sowie die Zwischenplatten 81, 82, 83 ... verschiebbar gelagert sind. Es versteht sich, daß eine konkrete Ausführungsform einer Hubplattform nach der Erfindung nur jeweils mit einer Art der Führungen ausgestattet ist, und daß in Figur 5 lediglich aus Gründen der Darstellungsmöglichkeit zwei Führungsarten 85, 86 an einer Hubplattform wiedergegeben sind.In Figure 5, two types of guides are shown: The guide 85 is a telescopic guide that can be pushed together in a base sleeve 851. It is possible to arrange the base sleeve 851 in the underfloor. The second type of guide is a rigid guide: [s-pillar 86, which cannot be pushed together and on which the lifting platform 7 and the intermediate plates 81, 82, 83 ... are slidably mounted. It goes without saying that a specific embodiment of a lifting platform according to the invention is only equipped with one type of guide, and that two guide types 85, 86 are shown on a lifting platform only for reasons of illustration.

In Figur 5a ist dasjenige Ventil 51 wiedergegeben, das in der Grundplatte 6 der Hubvorrichtung nach Figur 5 angeordnet ist. Das Ventil 51 besteht aus einer Führungsnabe mit Speichen 511, dem eigentlichen Ventilteller 512 sowie einem Stößel 513. Der Ventilteller 512 wird durch die Feder 514 an die Grundplatte 6 dichtend angedrückt. Durch einen Druck auf den Stößel 513 kann der Ventilteller 512 von der Grundplatte 6 abgehoben und das Ventil 51 geöffnet werden. In diesem Falle entweicht die Luft aus dem ersten Balg 21. Andererseits ist es aber ohne weiteres ersichtlich, daß bei einem überdruck in der Leitung 3 der Ventilteller 512 von der Grundplatte 6 abgehoben und der erste Balg 21 mit Druckluft gefüllt wird.5a shows that valve 51 which is arranged in the base plate 6 of the lifting device according to FIG. The valve 51 consists of a guide hub with spokes 511, the actual valve plate 512 and a tappet 513. The valve plate 512 is pressed against the base plate 6 in a sealing manner by the spring 514. By pressing the tappet 513, the valve plate 512 can be lifted off the base plate 6 and the valve 51 can be opened. In this case, the air escapes from the first bellows 21. On the other hand, it is readily apparent that the valve plate 512 is lifted off the base plate 6 in the event of an overpressure in the line 3 and the first bellows 21 is filled with compressed air.

In Figur 5b ist ein Ventil 52 wiedergegeben, wie dieses in den dünnen Zwischenplatten 81 zwischen jeweils zwei Bälgen 21, 22 vorgesehen ist. Dieses Ventil 52 hat praktisch den gleichen Aufbau wie das Ventil 51, nur mit dem Unterschied, daß der Stößel 523 kürzer ausgebildet ist. Die Funktionsweise dieses Ventils 52 ist so, daß bei einer Entleerung des ersten Balges 21 der Stößel 523 auf den Ventilteller 512 aufgesetzt und das Ventil 52 geöffnet wird. Hierdurch erfolgt eine Entleerung des zweiten Balges 22 usw. Bei einem Überdruck in der Leitung 3 werden die Bälge 21, 22 usw. nacheinander wieder gefüllt.FIG. 5b shows a valve 52 as is provided in the thin intermediate plates 81 between two bellows 21, 22 in each case. This valve 52 has practically the same structure as the valve 51, with the only difference that the plunger 523 is shorter. The operation of this valve 52 is such that when the first bellows 21 is emptied, the tappet 523 is placed on the valve plate 512 and the valve 52 is opened. This results in an emptying of the second bellows 22, etc. In the event of an overpressure in the line 3, the bellows 21, 22, etc. are filled again in succession.

In Figur 6 ist eine als selbständig einsetzbares Bauelement ausgebildete Hubvorrichtung 9 wiedergegeben. Die Hubvorrichtung 9 besteht aus einer Grundplatte 6 und der Hubplattform 7, zwischen denen sich der Balg 91 erstreckt. Die Führung erfolgt durch ein Spindelteleskop 92, das nach außen nicht sichtbar in der Mittelachse des Balges 91 angeordnet ist. Das Mittelteil 93 deJ Spindelteleskops 92 bestimmt den minimalen Abstand, bis zu dem das Teleskop 92 und damit die Hubvorrichtung 9 zusammenschiebbar ist.FIG. 6 shows a lifting device 9 designed as an independently usable component. The lifting device 9 consists of a base plate 6 and the lifting platform 7, between which the bellows 91 extends. The guidance takes place through a spindle telescope 92, which is arranged in the central axis of the bellows 91 and is not visible from the outside. The middle part 93 de J spindle telescope 92 determines the minimum distance to which the telescope 92 and thus the lifting device 9 is collapsible.

Figur 6 a zeigt einen Wandausschnitt des Balges 91 in vergrößerten Maßstab. Durch Ringe oder Spiralen 94 (Lutenspirale) wird die äußere Form des Balges 91 immer sichergestellt, und zwar unabhängig davon, ob die Hubvorrichtung 9 nur wenig oder maximal auseinandergefahren ist.FIG. 6 a shows a wall section of the bellows 91 on an enlarged scale. The outer shape of the bellows 91 is always ensured by rings or spirals 94 (lute spiral), regardless of whether the lifting device 9 has moved apart only slightly or to the maximum.
