Description

Die Erfindung betrifft eine Vorrichtung mit beweglichen Plattformen zum Abstellen von Fahrzeugen mit mindestens zwei Plattformen übereinander, die zusammen im wesentlichen in vertikaler Richtung bewegbar sind, um wahlweise eine der Plattformen mit einer mehreren Plattformen gemeinsamen Zufahrt zu verbinden.The invention relates to a device with movable platforms for parking vehicles with at least two platforms one above the other, which together can be moved essentially in the vertical direction in order to selectively connect one of the platforms with a common access platform.

Es sind Vorrichtungen zum Abstellen von Fahrzeugen auf beweglichen Plattformen bekannt, die so ausgestaltet sind, daß eine oder mehrere Plattformen mit den darauf abgestellten Fahrzeugen in einen Schacht unter der Ebene der Zufahrt absenkbar sind. Die oberste Plattform kann dabei ebenfalls als Stellplatz für ein Fahrzeug dienen. Es ist aber auch möglich, die Anordnung derart zu treffen, daß die oberste Plattform die beispielsweise in einer Durchfahrt angeordnet ist, als Fahrbahn für andere Zwecke dient.Devices for parking vehicles on movable platforms are known which are designed such that one or more platforms with the vehicles parked thereon can be lowered into a shaft below the level of the access road. The top platform can also serve as a parking space for a vehicle. However, it is also possible to make the arrangement in such a way that the uppermost platform, which is arranged, for example, in a passage, serves as a roadway for other purposes.

Eine bekannte Vorrichtung dieser Art arbeitet mit einer Schiene bzw. je einer Schiene zu beiden Seiten der Plattformen, an welcher Schiene je ein Schlitten beweglich ist. Der Schlitten trägt die Plattformen. Mittels einer Hubeinrichtung kann der Schlitten vertikal bewegt werden. Zusätzlich zu dieser Anordnung ist noch eine Einrichtung vorgesehen, die es ermöglicht, die Plattformen gegenüber dem Schlitten und der Schiene zu neigen. Die Nelgbarkeit der Plattformen bringt dabei den Vorteil, daß die Hubbewegung etwas geringer gehalten sein kann, als die Schachttiefe und daß es dennoch möglich ist, das eine, nämlich das angehobene Plattformende mit der Zufahrt zu verbinden.A known device of this type works with a rail or one rail on each side of the platforms, on which rail a carriage can be moved. The sled carries the platforms. The carriage can be moved vertically by means of a lifting device. In addition to this arrangement, a device is also provided which makes it possible to incline the platforms with respect to the slide and the rail. The ability of the platforms to be closed brings the advantage that the lifting movement can be kept somewhat less than the shaft depth and that it is nevertheless possible to connect one end, namely the raised platform end, to the driveway.

Da die Verteilung der Belastung von vorneherein nicht festliegt, da gewisse Unterschiede bei den Gewichten, die auf den Plattformen abgestellt sind, in Betracht gezogen werden müssen, ist es notwendig, die Schiene und den Schlitten sorgfältig auszubilden. Insbesondere die Schiene besitzt ein erhebliches Gewicht. Für die Montage im Schacht ist in der Regel ein Hebezeug notwendig und die Montage ist aufwendig.Since the distribution of the load is not fixed from the outset, since certain differences in the weights that are placed on the platforms have to be taken into account, it is necessary to train the rail and the slide carefully. The rail in particular has a considerable weight. A hoist is usually required for installation in the shaft and installation is complex.

Eine weitere Schwierigkeit bei der bekannten Konstruktion besteht darin, daß es nur mit Aufwand möglich ist, in der abgesenkten Stellung alle Teile in den Schacht einzufahren, so daß keine nach oben vorstehenden Bauteile gegeben sind. Dies sollte aber erreicht werden, um die Benützbarkeit der oberen Plattform beispielsweise als Durchfahrt nicht zu beeinträchtigen. Diese Schwierigkeiten sind im wesentlichen dadurch bedingt, daß die Schachttiefe annähernd der Hubhöhe entspricht, so daß bei einer Schienenlänge im Maße der Schachttiefe keine ausreichende Führung zwischen Schlitten und Schiene mehr gegeben ist. Es wird notwendig, entweder mit mehrteiligen Teleskopeinrichtungen zu arbeiten oder im Schacht zusätzliche Vertiefungen vorzusehen, um eine sichere gegenseitige Führung zu erhalten.Another difficulty with the known construction is that it is only possible with effort to retract all parts into the shaft in the lowered position, so that there are no components protruding upwards. This should be achieved, however, the Benützbarke i t of the upper platform, for example, not to interfere with the passage. These difficulties are essentially due to the fact that the shaft depth corresponds approximately to the lifting height, so that there is no longer sufficient guidance between the slide and the rail with a rail length equal to the shaft depth. It becomes necessary to either work with multi-part telescopic devices or to provide additional recesses in the shaft in order to obtain reliable mutual guidance.

Es ist Ziel der Erfindung die eingangs beschriebene Vorrichtung zum Abstellen von Fahrzeugen auf beweglichen Plattformen dadurch zu verbessern, daß der Herstellungsaufwand und der Montageaufwand wesentlich vereinfacht wird. Ein weiteres Ziel der Erfindung besteht darin, die Anordnung derart zu treffen, daß unterschiedliche Bewegungen oder Abmessungen leicht erhalten werden können, und zwar mit im wesentlichen den gleichen Bauteilen, so daß leicht verschiedene Typen von Abstellvorrichtungen geschaffen werden können.The aim of the invention is to improve the device described above for parking vehicles on movable platforms by substantially simplifying the manufacturing outlay and the assembly outlay. Another object of the invention is to provide the arrangement so that different movements or dimensions can be easily obtained with essentially the same components so that different types of parking devices can be easily created.

Zur Lösung dieser Aufgabe geht die Erfindung aus von einer Vorrichtung der eingangs beschriebenen Art und sie schlägt vor, daß ein erstes Lenkerparallelogramm oder ein erstes Paar von annähernd parallelen Lenkern vorgesehen ist, das sich im wesentlichen in horizontaler Richtung erstreckt, dessen eines Ende an einer ortsfesten Abstützung gelagert ist und dessen anderes Ende die Plattformen führt.To achieve this object, the invention is based on a device of the type described in the introduction, and it proposes that a first link parallelogram or a first pair of approximately parallel links is provided, which extends essentially in the horizontal direction, one end of which is at a fixed position Support is stored and the other end leads the platforms.

Es ist gefunden worden, daß mittels derart angeordneter erster Lenker die verschiedenen Probleme überraschend auf einfache Weise gelöst werden können. Zwar ergeben die Lenker bezüglich der Plattformen keine genaue vertikale Bewegung sondern eine Bewegung auf einer Kreisbahn. Da es aber möglich ist, ausreichend lange Lenker vorzusehen, erscheint dieser Umstand nicht als Nachteil. Es ist leicht möglich, auf jede der Plattform einen exakten Anschluß an die Zufahrt zu erreichen. Da die Lenker im wesentlichen nur auf Zug oder Druck beansprucht werden, ist ihre Konstruktion einfach. Es sind nur an einem geeigneten Profilmaterial die erforderlichen Gelenke anzubringen.It has been found that the various problems can surprisingly be solved in a simple manner by means of first links arranged in this way. The handlebars do not result in a precise vertical movement with respect to the platforms, but rather a movement on a circular path. However, since it is possible to provide sufficiently long handlebars, this does not appear to be a disadvantage. It is easily possible to get an exact connection to the access on each of the platforms. Since the handlebars are essentially only subjected to tension or pressure, their construction is simple. The required joints must only be attached to a suitable profile material.

Die Beherrschung der Hubhöhe und eine sichere Führung auch im stark angehobenen Zustand ergibt sich bei dieser Anordnung der Lenker von selbst. Andererseits werden im abgesenkten Zustand sämtliche Teile in den Schacht eintauchen und nicht nach oben vorstehen.Mastering the lifting height and reliable guidance, even in a strongly raised state, is a matter of course with this arrangement of the handlebars. On the other hand, in the lowered state, all parts are immersed in the shaft and do not protrude upwards.

Die Verbindung der einzelnen Plattformen kann bei der Erfindung in verschiedener Weise erfolgen. Bevorzugt wird ein vertikal angeordnetes Strebenpaar, wobei die Lenker an mindestens einer der Streben angreifen.The individual platforms can be connected in various ways in the invention. A vertically arranged pair of struts is preferred, the links engaging at least one of the struts.

In weiterer Ausbildung der Erfindung kann das Strebenpaar ein zweites Lenkerparallelogramm bilden, wobei dann die Plattformen neigbar sind.In a further embodiment of the invention, the pair of struts can form a second link parallelogram, in which case the platforms can be tilted.

Um die Neigungsbewegung der Plattformen zu erzielen, können an sich die herkömmlichen Bauweisen angewandt werden, beispielsweise eine Bauweise, bei der bei der Hubbewegung zunächst alle Plattformen geneigt werden und dann die geneigten Plattformen insgesamt angehoben werden. Auch der umgekehrte Vorgang ist möglich, also zunächst eine Anhebung der parallelen, horizontalen Plattformen, die dann am Ende der Hubbewegung eine Neigungsbewegung ausführen. Auch eine Überlagerung der Hubbewegung mit der Neigungsbewegung ist möglich. Diese Bewegungen können beispielsweise durch Zugglieder erzwungen werden. Bei einer bevorzugten Ausbildungsform der Erfindung ist ein Koppelungslenker zum Antrieb der Neigungsbewegung der Plattformen vorgesehen, wobei der Koppelungslenker von einem der ersten Lenker angetrieben ist.In order to achieve the inclination movement of the platforms, the conventional construction methods can be used per se, for example a construction in which all platforms are initially inclined during the lifting movement and then the inclined platforms are lifted as a whole. The reverse process is also possible, that is to say first of all an elevation of the parallel, horizontal platforms, which then execute an inclination movement at the end of the lifting movement. A superimposition of the lifting movement with the inclination movement is also possible. These movements can, for example, by Tension members are forced. In a preferred embodiment of the invention, a coupling link is provided for driving the inclination movement of the platforms, the coupling link being driven by one of the first links.

Diese Ausbildungsform läßt weitere Vorteile der erfindungsgemäßen Bauweise deutlich werden. Mittels des Koppelungslenkers, der von einem ersten Lenker angetrieben ist, läßt sich eine Vielzahl von unterschiedlichen Neigungsbewegungen der Plattformen erzielen. Dabei kann das eine oder andere Plattformende geneigt werden und auch der maximale Neigungswinkel kann den jeweiligen Bedürfnissen angepaßt werden. Dies alles läßt sich durch einfache Veränderung des Koppelungslenkers bzw. seiner Anlenkpunkte erzielen.This form of training makes further advantages of the construction according to the invention clear. A large number of different inclination movements of the platforms can be achieved by means of the coupling link, which is driven by a first link. One or the other platform end can be inclined and the maximum angle of inclination can also be adapted to the respective needs. All of this can be achieved by simply changing the coupling link or its articulation points.

Günstig ist es, wenn die feste Abstützung der ersten Lenker in der Nähe eines der beiden Enden der Plattformen angeordnet ist. Die die Plattform führenden Enden der ersten Lenker sind bei einer Vorrichtung mit zwei Plattformen etwa in der Plattformmitte angeordnet, bei einer Bauweise mit drei Plattformen etwa im Bereich der anderen Plattformenden.It is advantageous if the fixed support of the first link is arranged in the vicinity of one of the two ends of the platforms. The ends of the first link guiding the platform are arranged approximately in the middle of the platform in the case of a device with two platforms, in the area of the other platform ends in the case of a construction with three platforms.

Eine besonders günstige Ausführungsform der Erfindung wird erhalten, wenn die ersten Lenker nur annähernd parallel ausgerichtet sind und die Abstände der Gelenke der ersten Lenker, die dem Zufahrtsende der Plattformen zugewandt sind, etwas größer sind, als die Abstände der Gelenke an dem der Zufahrt abgewandten Ende der ersten Lenker.A particularly favorable embodiment of the invention is obtained if the first links are only approximately parallel and the distances between the joints of the first links, which face the entry end of the platforms, are somewhat larger than the distances of the joints at the end facing away from the entry the first driver.

Zur Erläuterung sei bemerkt, daß ein Parallelogramm selbstverständlich im strengen geometrischen Sinne dann nicht mehr gegeben ist, wenn von der Parallelität abgewichen wird. Zur Erleichterung des Verständnisses soll jedoch nachstehend jeweils der Begriff Parallelogramm auch dann beibehalten werden, wenn die Parallelität aller Teile zur Erzielung besonderer Wirkungen teilweise aufgegeben ist.As an explanation, it should be noted that a parallelogram is of course no longer given in the strict geometric sense if there is a deviation from parallelism. In order to facilitate understanding, however, the term parallelogram is to be retained in the following even if the parallelism of all parts in order to achieve special effects is partially abandoned.

Dadurch, daß bei einer Variante der Erfindung die ersten Lenker nur annähernd parallel ausgerichtet sind, werden die beiden Plattformen bei der Vertikalbewegung nicht lediglich parallel verschoben, sondern den beiden Plattformen wird zusätzlich eine Drehbewegung aufgezwungen. Dadurch läßt sich in einfacher Weise erreichen, daß die Plattformen beispielsweise zwar in der abgesenkten Stellung völlig horizontal ausgerichtet sind, daß die Plattformen aber in der angehobenen Stellung derart geneigt sind, daß die untere Plattform beispielsweise beim Befahren ein Gefälle aufweist. Der wesentliche Vorteil der Abweichung von der Parallelität der beiden Lenker besteht somit darin, daß alle oben beschriebenen zusätzlichen Elemente, um zusätzlich zur Hubbewegung noch eine Neigungsbewegung zu erreichen, eingespart werden.Due to the fact that in a variant of the invention the first links are only aligned approximately parallel, the two platforms are not only displaced in parallel during the vertical movement, but the two platforms are additionally forced to rotate. This can be achieved in a simple manner that the platforms, for example, are oriented completely horizontally in the lowered position, but that the platforms are inclined in the raised position such that the lower platform has a slope, for example when driving on it. The main advantage of the deviation from the parallelism of the two links is therefore that all the additional elements described above, in order to achieve an inclination movement in addition to the lifting movement, are saved.

In weiterer Ausgestaltung der Erfindung wird vorgeschlagen, daß die beiden Plattformen im wesentlichen starr miteinander verbunden sind. Wohl ist es an sich bekannt, zwei Plattformen einer Abstellvorrichtung für Kraftfahrzeuge starr miteinander zu verbinden und gemeinsam anzuheben und abzusenken. Im Hinblick auf die Erfindung wird aber durch die Benützung einer solchen Bauweise eine wesentliche, bauliche Vereinfachung bei Vergrößerung der Stabilität erreicht.In a further embodiment of the invention it is proposed that the two platforms are essentially rigidly connected to one another. It is well known per se to rigidly connect two platforms of a parking device for motor vehicles to one another and to raise and lower them together. With regard to the invention, however, the use of such a construction achieves a substantial structural simplification while increasing the stability.

Das erste Lenkerpaar ist an einer ortsfesten Abstützung gelagert, die vorzugsweise an dem der Zufahrt abgewandten Ende der Vorrichtung angeordnet ist. Zu erwähnen ist hier, daß sinngemäß auch eine Lagerung an einer Abstützung am Zufahrtsende möglich ist. Die Lagerung am anderen Ende ist jedoch günstiger, da mit einer geringeren Länge der Lenker ausgekommen werden kann. Dies ist bedingt dadurch, daß die Vertikalbewegung der Plattformen an diesem Plattformende geringer ist als am Zufahrtsende.The first pair of links is mounted on a stationary support, which is preferably arranged at the end of the device facing away from the access. It should be mentioned here that storage on a support at the end of the access is also possible. However, storage at the other end is cheaper because the handlebars can be used with a shorter length. This is due to the fact that the vertical movement of the platforms at this platform end is less than at the entrance end.

Eine besonders günstige Ausführungsform der Erfindung ist gekennzeichnet durch eine in der abgesenkten Stellung der Plattformen senkrechte Verbindungsstrebe zwischen den Plattformen, an der die einen Gelenke der gleichlangen Lenker übereinander angelenkt sind. Diese Ausbildung gibt eine klare und einfache Bauweise und zeigt außerdem, daß der erfindungsgemäße Effekt durch eine überraschend kleine Änderung bzw. Abweichung von der exakten Parallelität der Lenker erreicht wird.A particularly favorable embodiment of the invention is characterized by a vertical connecting strut between the platforms in the lowered position of the platforms, on which the one articulation of the links of the same length are articulated one above the other. This training gives a clear and simple design and also shows that the effect according to the invention is achieved by a surprisingly small change or deviation from the exact parallelism of the handlebars.

Beim Ausführungsbeispiel nach den Fig. 1 oder 2 umfaßt die erfindungsgemäße Vorrichtung die obere Plattform 6 und die untere Plattform 7. Die Plattformen und die zugehörigen Einrichtungen sind so ausgebildet und angeordnet, daß sie im abgesenkten Zustand (Fig. 1) sämtlich vom Schacht 15 aufgenommen werden. In dem Schacht 15 ist ein Grundgestell 16 angeordnet, das aus dem horizontalen Teil 17 und dem vertikalen Teil besteht. Der Teil 5 bildet eine Abstützung für die beiden Lenker und 2 eines ersten Lenkerparallelogramms. Die entsprechenden Gelenke sind mit 19 und 20 bezeichnet. Die freien Enden dieser Lenker 1 und 2 sind mittels der Gelenke 21 und 22 mit der Strebe 11 verbunden, die sich zwischen den beiden Plattformen 6 und 7 erstreckt. Die Strebe 11 ist gelenkig mit diesen Plattformen verbunden und zwar durch das Gelenk 23 mit der Plattform 6 und das Gelenk 22 mit der Plattform 7, an dem auch der Lenker 2 angreift. Parallel zur Strebe 11 ist die Strebe 12 angeordnet. Die zugehörigen Gelenke sind mit 24 und 25 bezeichnet. Die Streben 11 und 12 stellen somit ein zweites Lenkerparallelogramm dar.In the embodiment according to FIGS. 1 or 2, the device according to the invention comprises the upper platform 6 and the lower platform 7. The platforms and the associated devices are designed and arranged such that they are all received by the shaft 15 in the lowered state (FIG. 1) will. In the shaft 15, a base frame 16 is arranged, which consists of the horizontal part 17 and the vertical part. Part 5 forms a support for the two links and 2 of a first link parallelogram. The corresponding joints are designated 19 and 20. The free ends of these links 1 and 2 are connected by means of the joints 21 and 22 to the strut 11 which extends between the two platforms 6 and 7. The strut 11 is connected in an articulated manner to these platforms, specifically by means of the articulation 23 with the platform 6 and the articulation 22 with the platform 7, on which the handlebar 2 also acts. The strut 12 is arranged parallel to the strut 11. The associated Ge steering are designated 24 and 25. The struts 11 and 12 thus represent a second handlebar parallelogram.

Zwischen dem Gelenk 25 und einem Gelenk 26 am Lenker erstreckt sich das Koppelungsglied 13.The coupling member 13 extends between the joint 25 and a joint 26 on the handlebar.

Der hydraulische Antriebszylinder 14, der die Plattformen 6 und 7 bewegt, stützt sich bei 23 an der oberen Plattform 6 und bei 18 am Teil 17 des Grundgestelles ab.The hydraulic drive cylinder 14, which moves the platforms 6 and 7, is supported at 23 on the upper platform 6 and at 18 on part 17 of the base frame.

Es wird bemerkt, daß die beschriebene Anordnung von Lenkern Koppelungsglied und Zylinder in der Regel die beiden Seiten der Plattform 6 und 7 angeordnet sind. Um einen Gleichlauf zu erreichen, erstreckt sich zwischen den Gelenken 19 der Lenker 1 zu beiden Seiten ein mit dem Lenkern 1 drehfestes Bauteil, beispielsweise ein Rohr 27, so daß die Lenker 1 beider Seiten zusammen mit dem Rohr 27 eine Gabel bilden. Ein Gleichlauf kann auch durch andere Mittel herbeigeführt werden, beispielsweise durch hydraulische Koppelung der beiden Zylinder 14 zu beiden Seiten der Plattformen.It is noted that the described arrangement of links coupling element and cylinder are usually arranged on both sides of the platform 6 and 7. In order to achieve synchronism, between the joints 19 of the link 1 extends on both sides a component which is fixed to the link 1, for example a tube 27, so that the link 1 on both sides together with the tube 27 form a fork. Synchronization can also be brought about by other means, for example by hydraulically coupling the two cylinders 14 on both sides of the platforms.

Wird der Zylinder 14 in der Stellung der Fig. 1 beaufschlagt, bewegt sich die Vorrichtung aus der Stellung der Fig. 1 in die Stellung der Fig. 2. Bei der Hubbewegung des ersten aus den Lenkern 1 und 2 bestehenden Lenkerparallelogramms wird das Koppelungsglied 13 angetrieben, das seinerseits das aus den Lenkern 11 und 12 bestehende zweite Lenkerparallelogramm antreibt. Auf diese Weise wird in der angehobenen Stellung eine Neigung der Plattformen 6 und 7 erhalten, das Ende 28 der unteren Plattform 7 wird auf diese Weise an die Zufahrt 29 angeschlossen, obwohl die Hubhöhe beider Plattformen nicht der Schachttiefe entspricht.If the cylinder 14 is loaded in the position of FIG. 1, the device moves from the position of FIG. 1 to the position of FIG. 2. During the lifting movement of the first link parallelogram consisting of the links 1 and 2, the coupling member 13 is driven , which in turn drives the second parallelogram of the handlebars 11 and 12. In this way, an inclination of the platforms 6 and 7 is obtained in the raised position, the end 28 of the lower platform 7 is connected in this way to the driveway 29, although the lifting height of both platforms does not correspond to the shaft depth.

Zur Versteifung der Zufahrtsstellung liegt das gegenüberliegende Ende 30 der unteren Plattform 7 an einem Anschlag 31 an, der Teil der Abstützung 5 ist.To stiffen the access position, the opposite end 30 of the lower platform 7 bears against a stop 31 which is part of the support 5.

Die gezeigte Bauweise kann einfach in verschiedener Richtung verändert werden. Wird ein etwas längeres Koppelungsglied 13 benützt, und dieses zwischen den Gelenkpunkten 25 und 21 angeordnet, ergibt sich bei der Hubbewegung keine Neigungsbewegung. Bei einer anderen Variante kann beispielsweise das Koppelungsglied 13 an einem mit strichpunktierten Linien angedeuteten Verlängerung des lenkers 1 in einem Gelenk 32 befestigt werden. Die Plattformen 6 und 7 würden dann in der angehobenen Stellung eine entgegengesetzt gerichtete Neigung aufweisen. Wenn gewünscht wird, kann die Neigung der Plattformen auch durch andere Mittel erzielt werden. Dies ist in der Fig. angedeutet. Die 'Fig. 3 zeigt ein Ausführungsbeispiel der Erfindung mit insgesamt drei übereinander angeordneten Plattformen 8, 9 und 10. Die ersten Lenker3 und 4 bilden ein Lenkerparallelogramm und es ist klar, daß bei Beaufschlagung des Zylinders 14 eine Hubbewegung erreicht wird, so daß wahlweise entweder die Plattform 8, 9 oder 10 an die Zufahrt 29 angeschlossen werden kann.The design shown can easily be changed in different directions. If a somewhat longer coupling member 13 is used and this is arranged between the articulation points 25 and 21, there is no inclination movement during the lifting movement. In another variant, the coupling member 13 can, for example, be attached to an extension of the handlebar 1, indicated by dash-dotted lines, in a joint 32. The platforms 6 and 7 would then have an oppositely directed inclination in the raised position. If desired, the inclination of the platforms can also be achieved by other means. This is indicated in the figure. The 'Fig. 3 shows an embodiment of the invention with a total of three platforms 8, 9 and 10 arranged one above the other. The first links 3 and 4 form a link parallelogram and it is clear that when the cylinder 14 is acted on, a lifting movement is achieved, so that either the platform 8, 9 or 10 can be connected to the driveway 29.

Die Neigungsbewegung der Plattformen 8, 9 und 10, die durch die beiden Streben 11 und 12 verbunden sind, kommt dadurch zustande, daß sich zwischen dem Punkt 33 an der unteren Plattform 10 und dem Gelenkpunkt 23 zwischen der Strebe 11 und der oberen Plattform 8 ein Zugglied 34 erstreckt. In der abgesenkten Stellung ist das Zugglied 34 teilweise zusammengeschoben. Beim Anheben wird zunächst das Ende 35 der unteren Plattform 10 auf der entsprechenden Unterlage aufruhen bis die maximale Neigungsstellung der Plattformen und die maximale Länge des Zugglieds erreicht wird. Dann wird das Zugglied 34 die geneigten Plattformen anheben. Die gezeigte Ausbildung und Anordnung des Zugglieds ist nur beispielsweise zu verstehen und leicht durch andere Bauweisen zu ersetzen.The inclination movement of the platforms 8, 9 and 10, which are connected by the two struts 11 and 12, is due to the fact that between the point 33 on the lower platform 10 and the hinge point 23 between the strut 11 and the upper platform 8 Tension member 34 extends. In the lowered position, the tension member 34 is partially pushed together. When lifting, the end 35 of the lower platform 10 will first rest on the corresponding base until the maximum inclination of the platforms and the maximum length of the tension member is reached. Then the tension member 34 will raise the inclined platforms. The design and arrangement of the tension member shown is only to be understood as an example and can easily be replaced by other designs.

Die Ausführungsbeispiele können in verschiedener Weise gegenüber den Darstellungen der Zeichnungen abgewandelt werden. Die Abstützung 5, die in der Zeichnung im Bereich des einen Plattformendes angeordnet ist, kann, wenn gewünscht, auch neben den Plattformen vorgesehen werden. Während bei der Bauweise mit zwei Plattformen die Länge der Lenker des ersten Lenkerparallelogramms ungefähr der halben Plattformlänge entspricht, empfiehlt es sich, bei der Bauweise mit drei Plattformen Lenker annähernd in der Länge der Plattformen vorzusehen.The exemplary embodiments can be modified in various ways compared to the illustrations in the drawings. The support 5, which is arranged in the drawing in the area of the one platform end, can, if desired, also be provided next to the platforms. While in the construction with two platforms the length of the handlebars of the first parallelogram corresponds to approximately half the length of the platform, it is advisable to provide the handlebars in the construction with three platforms approximately in the length of the platforms.

Es sind auch Bauweisen verwirklichbar, bei denen die Plattformen eine unterschiedliche Neigung aufweisen, beispielsweise dadurch, daß die Lenker 1 und 2 nicht parallel angeordnet werden. Dies kann bei besonderen Platzverhältnissen oder -bedürfnissen von Vorteil sein.It is also possible to implement designs in which the platforms have different inclinations, for example in that the links 1 and 2 are not arranged in parallel. This can be an advantage in the case of special space conditions or needs.

Beim Ausführungsbeispiel nach den Fig. 4 und 5 ist die Strebe 11 starr an der Plattform 6 befestigt, während die Befestigung an der Plattform 7 mittels eines Gelenkes 36 erfolgt, das jedoch allein die Aufgabe hat, Verformungen unter der Belastung zuzulassen bzw. die Montage zu erleichtern. Zwischen den beiden Plattformen 6 und 7 erstreckt sich ferner noch die Strebe 12, die ebenfalls durch Gelenke 25 und 24 mit den Plattformen verbunden sind, die eine dem Gelenk36 ähnliche Funktion besitzen.In the exemplary embodiment according to FIGS. 4 and 5, the strut 11 is rigidly attached to the platform 6, while the attachment to the platform 7 is carried out by means of a joint 36, which, however, has the sole task of permitting deformation under the load or of mounting facilitate. Between the two platforms 6 and 7 also extends the strut 12, which are also connected by joints 25 and 24 to the platforms which have a function similar to the joint 36.

Zwischen dem horizontalen Teil 17 und der Plattform 6 erstreckt sich ferner der hydraulische Antriebszylinder 14.The hydraulic drive cylinder 14 also extends between the horizontal part 17 and the platform 6.

Die Gelenke 21 und 22 an der Strebe 11 sind bei abgesenkter Plattform exakt übereinander angeordnet und die Lenker 1 und 2 sind auch gleich lang. Der Abstand der Gelenke 19 und 20 am Teil der Abstützung (Fig. 4 und 5) ist jedoch geringer als der Abstand der Gelenke 21 und 22. Es ist klar, daß bei diesen Maßangaben die Gelenke 19 und 20 auch nich mehr exakt übereinander angeordnet sind, sondern daß das Gelenk 19 von der Zufahrt 29 einen etwas größeren Abstand aufweist, als das Gelenk 20. Durch die Abweichung von der Parallelität bei den Lenkern 1 und 2 bildet sich in der Verlängerung der Lenker 1 und 2 jeweils ein Momentandrehpol und bei der Beaufschlagung des Zylinders 14 erfahren die miteinander verbundenen Plattformen 6 und 7 neben der Hubbewegung jeweils auch eine Drehbewegung um diesen Momentandrehpol, so daß in der angehobenen Stellung nach der Fig. 2 beide Plattformen 6 und 7 eine Neigung aufweisen, die die Befahrbarkeit der Plattform 7 in keiner Weise beeinträchtigt, die aber den erheblichen Vorteil hat, daß die gesamte Hubbewegung geringer ist als die Tiefe des Schachtes 15, wodurch unter anderem auch der Platzbedarf in der Höhe verringert wird.When the platform is lowered, the joints 21 and 22 on the strut 11 are arranged exactly one above the other and the links 1 and 2 are also of the same length. The distance between the joints 19 and 20 on the part of the support (FIGS. 4 and 5) is, however, less than the distance between the joints 21 and 22. It is clear that with these dimensions, the joints 19 and 20 are no longer arranged exactly one above the other , but that the joint 19 from the driveway 29 has a slightly greater distance than the joint 20. Due to the deviation from the parallelism in the handlebars 1 and 2 in the extension of the handlebars 1 and 2, a momentary turning pole is formed and when it is acted upon of the cylinder 14 experience the interconnected plate form 6 and 7 in addition to the lifting movement also a rotary movement around this instantaneous turning pole, so that in the raised position according to FIG. 2 both platforms 6 and 7 have an inclination which in no way impairs the accessibility of the platform 7, but which the considerable The advantage is that the total lifting movement is less than the depth of the shaft 15, which among other things also reduces the space requirement in height.

Die Erfindung läßt sich auch verwirklichen, wenn die Länge der Lenker 1 und 2 geringfügig voneinander verschieden ist, wobei dann die Abweichungen von der Parallelität noch geringer sein können.The invention can also be implemented if the length of the links 1 and 2 is slightly different from one another, in which case the deviations from parallelism may be even smaller.
