Abstract

The mechanism providing uniform movement consists of the torsion-proof tube (20), which is fixedly arranged, and the connecting rods (1 and 19) connected thereto. The connecting rods (19) at the ends of the torsion tube (20) are firmly connected to the torsion tube, and the connecting rods (1) form the connection to the junction point (2) of the strut (3) between the two platforms (4 and 7). The joining of the connecting rods (1) to the junction point (2) improves the functioning of the mechanism providing uniform movement and simplifies the constructional complexity. If desired, the connecting rod can also be articulated at the lower junction point (5) of this strut (3) without constructional changes being necessary.

Description

Die Erfindung betrifft eine Gleichlaufvorrichtung für Einrichtungen zum Abstellen von Kraftfahrzeugen auf zwei Plattformen übereinander, wobei die Plattformen über Streben gekoppelt und gemeinsam bewegbar sind, um diese wahlweise an eine gemeinsame Zufahrt anzuschließen, und die Gleichlaufvorrichtung aus Lenkeranordnungen besteht, die an den Enden eines verwindungssteifen Elements angeordnet sind und an beiden Seiten einer der beiden Plattformen angreifen.The invention relates to a synchronizing device for devices for parking motor vehicles on two platforms one above the other, the platforms being coupled via struts and being movable together in order to connect them optionally to a common access, and the synchronizing device consisting of handlebar arrangements which are arranged at the ends of a torsionally rigid element are arranged and attack one of the two platforms on both sides.

Eine Gleichlaufvorrichtung dieser Gattung ist beispielsweise bekannt geworden durch die DE-OS 30 26 746. Diese Gleichlaufvorrichtung besteht im wesentlichen aus einem ortsfest gelagerten, torsionssteifen Rohr, das an seinem Ende je mit einem Lenker bzw. Hebelarm versehen ist. An diesen ersten Lenker an jedem Ende des Rohres ist über ein Gelenk ein weiterer Lenker angeschlossen, der seinerseits wiederum gelenkig an einer der Plattformen angreift.A synchronizing device of this type is known for example from DE-OS 30 26 746. This synchronizing device essentially consists of a stationary, torsionally rigid tube, which is provided at its end with a handlebar or lever arm. A further link is connected to this first link at each end of the tube via a joint, which in turn articulates on one of the platforms.

Einrichtungen zum Abstellen von Kraftfahrzeugen auf zwei Plattformen übereinander besitzen in der Regel auf beiden Seiten der Plattformen je einen Hubantrieb, beispielsweise einen Hydraulikzylinder. Dieser Hydraulikzylinder wirkt beispielsweise auf eine der Plattformen, beispielsweise auf die obere Plattform. Diese Plattform ist wiederum über Streben, Lenker oder ähnliche Mittel mit der anderen Plattform, also der unteren Plattform, verbunden. Beim Hubvorgang, bei dem im allgemeinen auch eine Neigung der Plattformen zur besseren Befahrbarkeit angestrebt wird, ergibt sich regelmäßig ein Unterschied in den Bewegungen der beiden Seiten jeder Plattform. Dies kann durch eine unterschiedliche Belastung der Plattformen bedingt sein, beispielsweise durch Fahrzeuge, die nicht genau in der Mitte stehen. Auch andere Einflüsse können eine ungleichförmige Bewegung der Plattformseiten zur Folge haben. Beispielsweise können einseitige Widerstände auftreten oder die Beaufschlagung der Hubeinrichtungen ist aus irgendwelchen Gründen unterschiedlich.Devices for parking motor vehicles on two platforms one above the other generally have a lifting drive, for example a hydraulic cylinder, on both sides of the platforms. This hydraulic cylinder acts, for example, on one of the platforms, for example on the upper platform. This platform is in turn connected to the other platform, that is to say the lower platform, via struts, handlebars or similar means. During the lifting process, in which an inclination of the platforms for better accessibility is generally also sought, there is regularly a difference in the movements of the two sides of each platform. This can be caused by different loads on the platforms, for example by vehicles that are not exactly in the middle. Other influences can also result in non-uniform movement of the platform sides. For example, one-sided resistances can occur or the loading of the lifting devices is different for some reason.

Durch die Gleichlaufvorrichtung soll erreicht werden, dar an der Ansatzstelle der Gleichlaufvorrichtung an einer der Plattformen diese Ansatzstellen im wesentlichen gleiche Höhenlagen einnehmen, so dar die Verformungen oder Verwindungen der Plattform reduziert werden. Der Gleichlauf der einen Plattform wird auch zu einem Gleichlauf der anderen Plattform führen.The aim of the synchronizing device is to ensure that at the starting point of the synchronizing device on one of the platforms, these starting points assume essentially the same height, so that the deformations or twists of the platform are reduced. The synchronization of one platform will also cause the other platform to synchronize.

Bei den bekannten Konstruktionen greift die Gleichlaufvorrichtung in der Nähe des Endes der Plattform an dieser an. Diese Anordnung wird deshalb getroffen, weil davon ausgegangen wird, daß an den Plattformenden die auszugleichenden Differenzen der Lage der beiden Seiten der Plattformen am größten sind, und somit die Gleichlaufvorrichtung die größte Wirkung äußert. Ein Angriffspunkt der Gleichlaufvorrichtung, beispielsweise in der Nähe der Hydraulikzylinder, könnte zwar dazu führen, daß unterschiedliche Hubhöhen der Hydraulikzylinder ausgeglichen werden. Eine Verwindung der Plattformen könnte hierdurch aber nicht beeinflußt werden.In the known constructions, the synchronizing device acts on the platform near the end thereof. This arrangement is made because it is assumed that the differences to be compensated for the position of the two sides of the platforms are greatest at the platform ends, and thus the synchronizing device has the greatest effect. A point of application of the synchronizing device, for example in the vicinity of the hydraulic cylinders, could lead to different lifting heights of the hydraulic cylinders being compensated for. A twisting of the platforms could not be influenced by this.

Es ist Aufgabe der Erfindung, eine Gleichlaufvorrichtung der eingangs angegebenen Gattung dahingehend weiter zu verbessern, daß die Wirkung der Gleichlaufvorrichtung auf die beiden Plattformen gesteigert und der Gleichlauf verbessert wird.It is an object of the invention to further improve a synchronous device of the type specified in the introduction in such a way that the effect of the synchronous device on the two platforms is increased and the synchronous operation is improved.

Zur Lösung dieser Aufgabe geht die Erfindung aus von einer Gleichlaufvorrichtung der eingangs angegebenen Gattung und schlägt vor, daß die Lenker der Gleichlaufvorrichtung an den Verbindungsstellen der Streben mit einer der Plattformen angreifen.To achieve this object, the invention is based on a synchronizing device of the type specified at the outset and proposes that the control arm of the synchronizing device attack at the connection points of the struts with one of the platforms.

Durch die Erfindung wird zunächst einmal erreicht, daß eine besondere Angriffsstelle der Gleichlaufvorrichtung an einer der Plattformen eingespart wird. Die Gleichlaufvorrichtung greift an der Stelle an, an der schon die Strebe angreift, was die Herstellung vereinfacht.The invention first of all ensures that a special point of attack of the synchronizing device on one of the platforms is saved. The synchronizing device engages at the point where the strut already engages, which simplifies production.

Der wesentliche Vorteil der Erfindung besteht insbesondere darin, daß die Gleichlaufvorrichtung auf diese Weise wesentlich stärker auch an der anderen Plattform wirksam wird, als dies bisher möglich war. Da die Gleichlaufvorrichtung nicht nur an der Plattform angreift, sondern auch an der Strebe, wird über diese Strebe unmittelbar die andere Plattform zum Gleichlauf gezwungen. Verformungen der Plattform zwischen der Angriffsstelle der Gleichlaufvorrichtung einerseits und der Verbindungsstelle der Strebe andererseits, die sich bisher auf den Gleichlauf der anderen Plattform übertrugen, sind eliminiert.The main advantage of the invention is, in particular, that the synchronization device is essential in this way more effective on the other platform than was previously possible. Since the synchronizing device acts not only on the platform but also on the strut, the other platform is forced to synchronize directly via this strut. Deformations of the platform between the point of attack of the synchronizing device on the one hand and the connection point of the strut on the other hand, which have previously been transferred to the synchronism of the other platform, have been eliminated.

Im allgemeinen verwendet die Erfindung Gleichlaufvorrichtungen bestehend aus zwei Lenkerpaaren, wie bei der vorbekannten, eingangs geschilderten Konstruktion. Es können aber auch Gleichlaufvorrichtungen angewandt werden, die nur einen einzigen Lenker sowie eine Schienenführung besitzen, wie diese in der DE-OS 30 48 217 beschrieben ist. Wird eine Gleichlaufvorrichtung mit zwei Lenkerpaaren benützt, so empfiehlt es sich, das torsionssteife Rohr ortsfest anzuordnen und die Bauweise ferner so zu wählen, daß die Verbindungsstrebe der Plattformen in der Nähe der Plattformenden angeordnet wird, um den Abstand zum Torsionsrohr zu verringern. Sollten beim erfindungsgemäßen Vorschlag gegebenenfalls längere Lenker für die Gleichlaufvorrichtung notwendig werden, ist dies ohne Nachteil, da der bauliche Aufwand hierfür nicht ins Gewicht fällt.In general, the invention uses synchronous devices consisting of two pairs of links, as in the previously known construction described above. But it can also be used synchronous devices that have only a single link and a rail guide, as described in DE-OS 30 48 217. If a synchronizing device with two pairs of links is used, it is advisable to arrange the torsionally rigid tube in a fixed position and to further select the construction so that the connecting strut of the platforms is arranged near the platform ends in order to reduce the distance to the torsion tube. If, in the proposal according to the invention, longer links may be necessary for the synchronizing device, this is without disadvantage since the structural effort for this is negligible.

Die Erfindung ist beispielsweise bei starr mit den beiden Plattformen oder mit einer der Plattform verbundenen Streben anwendbar. Die Erfindung wird jedoch insbesondere dann angewandt, wenn die Streben gelenkig mit der betreffenden Plattform verbunden sind. In diesem Falle bilden die Strebengelenke gleichzeitig auch die Gelenke für die Lenker der Gleichlaufvorrichtung.The invention is applicable, for example, to struts rigidly connected to the two platforms or to one of the platforms. However, the invention is used in particular when the struts are articulated to the platform in question. In this case, the strut joints also form the joints for the control arm of the synchronizing device.

Ein weiterer Vorteil wird bei der erfindungsgemäßen Vorrichtung dann erhalten, wenn die beiden Verbindungsstellen einer Strebe an den beiden Plattformen wahlweise als Anlenkstellen des einen Lenkers der Gleichlaufvorrichtung dienen. Hierdurch läßt sich erreichen, daß je nach den örtlichen Bedürfnissen und Wünschen die Gleichlaufvorrichtung entweder an der oberen Plattform oder an der unteren Plattform angreift. Der Angriff der Gleichlaufvorrichtung an der oberen Plattform ist manchmal nicht erwünscht, da beim Betreten der in der Einfahrtstellung befindlichen unteren Plattform die Lenker stören können.A further advantage is obtained in the device according to the invention if the two connection points of a strut on the two platforms serve optionally as articulation points of the one link of the synchronizing device. In this way it can be achieved that, depending on the local needs and wishes, the synchronizing device acts either on the upper platform or on the lower platform. The attack of the synchronizing device on the upper platform is sometimes not desirable, since the handlebars can interfere when entering the lower platform in the entry position.

In anderen Fällen erschweren zusätzliche Einbauten die Verbindungen der Lenker mit der unteren Plattform. Bei der erfindungsgemäßen Anordnung kann gegebenenfalls noch zum Zeitpunkt der Montage die eine oder andere Auswahl getroffen werden, ohne daß dies mit einem Zusatzaufwand verbunden wäre.In other cases, additional internals make it difficult to connect the handlebars to the lower platform. In the arrangement according to the invention, one or the other selection can optionally be made at the time of assembly, without this being associated with additional expenditure.

In the drawing, an embodiment of the invention is shown schematically. Show it:

a side view of a device for parking motor vehicles with a synchronization device according to the invention in the lowered position of the two platforms, and
Fig. 2
a representation of FIG. 1 corresponding to the side view of the same device in the raised position of the platforms.

Beim gezeigten Ausführungsbeispiel sind die beiden Plattformen 4 und 7 an einem Schlitten 8 gelagert, der am Ständer 9 in vertikaler Richtung bewegbar ist. Für die Bewegung des Schlittens 8 ist der Hydraulikzylinder 10 vorgesehen. Am unteren Ende des Schlittens 8 ist die Plattform 7 im Gelenk 11 gelagert, während am oberen Ende des Schlittens 8 und auch des Ständers 9 je eine Ausnehmung 12 bzw. 13 vorgesehen ist, die je nach der Stellung der beiden Plattformen den Zapfen 14 aufnimmt. In der abgesenkten Stellung ruht dabei der Zapfen 14 der oberen Plattform 4 in der Ausnehmung 13 des Ständers 9, und in der angehobenen Stellung ruht der Zapfen 14 in der Ausnehmung 12 des Schlittens 8.In the exemplary embodiment shown, the two platforms 4 and 7 are mounted on a carriage 8 which can be moved in the vertical direction on the stand 9. The hydraulic cylinder 10 is provided for the movement of the carriage 8. At the lower end of the slide 8, the platform 7 is mounted in the joint 11, while at the upper end of the slide 8 and also the stand 9 there is a recess 12 or 13, which receives the pin 14 depending on the position of the two platforms. In the lowered position, the pin 14 of the upper platform 4 rests in the recess 13 of the stand 9, and in the raised position, the pin 14 rests in the recess 12 of the slide 8.

Der Anschlag 15 und das Zugglied 16 begrenzen die Bewegungsmöglichkeiten der unteren Plattform und damit auch der oberen Plattform. Beim gezeigten Ausführungsbeispiel ist dabei vorgesehen, daß der Ständer 9 mit dem Schlitten 8 näher dem der Einfahrt 18 abgewandten Ende 17 der Plattformen 4 bzw. 7 angeordnet ist, so daß durch die Schwerpunktslage der beladenen oder auch der unbeladenen Plattformen immer ein Drehmoment im Sinne des Uhrzeigers auf die Plattformlager 11 bzw. 14 wirkt, so daß der Anschlag 15 bzw. das Zugglied 16 wirksam sind.The stop 15 and the tension member 16 limit the possibilities of movement of the lower platform and thus also of the upper platform. In the embodiment shown, it is provided that the stand 9 with the carriage 8 is arranged closer to the end 17 of the platforms 4 and 7 facing away from the entrance 18, so that due to the center of gravity of the loaded or also the unloaded platforms, a torque in the sense of Clockwise acts on the platform bearings 11 and 14, so that the stop 15 and the tension member 16 are effective.

Die beiden Plattformen 7 und 4 sind durch die Strebe 3 miteinander verbunden, deren obere Verbindungsstelle an der Plattform 4 mit 2 und deren untere Verbindungsstelle an der Plattform 7 mit 5 bezeichnet ist. Im gezeigten Ausführungsbeispiel ist die Strebe 3 als Lenker gestaltet, und die Verbindungsstellen 2 bzw. 5 sind Gelenke. Bei einer anderen Bauweise einer Vorrichtung zum Abstellen von Fahrzeugen, an der die erfindungsgemäße Gleichlaufvorrichtung einsetzbar ist, kann die Strebe auch starr mit einer oder mit beiden Plattformen verbunden sein.The two platforms 7 and 4 are connected to each other by the strut 3, the upper connection point on the platform 4 with 2 and the lower connection point on the platform 7 with 5. In the embodiment shown, the strut 3 is designed as a handlebar, and the connection points 2 and 5 are joints. In another construction of a device for parking vehicles, on which the synchronization device according to the invention can be used the strut may also be rigidly connected to one or both platforms.

Es wird bemerkt, daß sowohl die Ständeranordnung als auch die Strebe 3 jeweils zu beiden Seiten der Plattformen 4 bzw. 7 angeordnet sind.It is noted that both the stand arrangement and the strut 3 are arranged on either side of the platforms 4 and 7, respectively.

Die Gleichlaufvorrichtung besteht im wesentlichen aus dem ortsfest gelagerten Torsionsrohr 20, das an seinen Enden starr mit je einem Lenker 19 verbunden ist. Bei ausreichender Torsionssteifigkeit des Rohres 20 werden die beiden Lenker 19 zu beiden Seiten der Plattformen im wesentlichen immer eine parallele Lage einnehmen. An die Lenker 19 sind über die Gelenke 21 die Lenker 1 angeschlossen, die im gezeigten Ausführungsbeispiel an der Verbindungsstelle 2 angelenkt sind. Diese Lenker 1 sind nur zug- oder druckbeansprucht, nicht jedoch auf Biegung.The synchronizing device essentially consists of the stationary torsion tube 20, which is rigidly connected at its ends to one link 19 each. With sufficient torsional rigidity of the tube 20, the two links 19 will essentially always assume a parallel position on both sides of the platforms. The links 1 are connected to the links 19 via the joints 21 and are articulated at the connection point 2 in the exemplary embodiment shown. These handlebars 1 are only subjected to tensile or compressive stress, but not to bend.

Wenn nun infolge ungleichmäßiger Beladung der Plattformen 4 bzw. 7 oder auch infolge ungleichförmiger Beaufschlagung der Hydraulikzylinder 10 zu beiden Seiten der Plattformen, oder auch aus anderen Gründen, die linke und die rechte Seite der Plattformen nicht parallel ausgerichtet bleiben, sondern sich die beiden Plattformen verwinden, oder wenn aus den gleichen Gründen die eine Seite der Plattformen etwas stärker angehoben ist, als die andere Seite der Plattformen, wirkt die Gleichlaufvorrichtung aus den Teilen 1, 19 und 20 dem entgegen und versucht, die Verbindungsstellen 2 jeweils in gleicher Höhe zu halten. Über die Streben 3 zu beiden Seiten der Plattformen wird sich diese Wirkung auch auf die untere Plattform 7 äußern.If, as a result of uneven loading of the platforms 4 or 7 or also as a result of uneven loading of the hydraulic cylinders 10 on both sides of the platforms, or for other reasons, the left and right sides of the platforms do not remain aligned, but the two platforms twist , or if, for the same reasons, one side of the platforms is raised slightly more than the other side of the platforms, the synchronizing device from parts 1, 19 and 20 counteracts this and tries to keep the connection points 2 each at the same height. This effect will also manifest itself on the lower platform 7 via the struts 3 on both sides of the platforms.

In der Zeichnung ist mit strichpunktierten Linien 6 und 22 eine andere Anordnung der Lenker 1 und 19 angedeutet, die ohne weiteres bei der Erfindung angewandt werden kann. In diesem Falle ist dann der Lenker 1 mit der unteren Verbindungsstelle 5 der Strebe 3 an der Plattform 7 verbunden.In the drawing, dash-dotted lines 6 and 22 indicate another arrangement of the links 1 and 19, which can easily be used in the invention. In this case, the handlebar 1 is then connected to the lower connection point 5 of the strut 3 on the platform 7.

Die Fig. 2 macht deutlich, daß in der angehobenen Stellung die Gleichlaufvorrichtung mit den Lenkern 1 und 19 gegebenenfalls hinderlich sein kann beim Betreten der unteren Plattform 7 in deren Befahrstellung. Wenn dagegen die Anordnung benutzt wird, bei der die Lenker mit strichpunktierten Linien 6 bzw. 22 angedeutet sind, verbleiben die Lenker immer unterhalb der unteren Plattform 7, benötigen allerdings dort hinreichend Platz für ihre Bewegungen.Fig. 2 makes it clear that in the raised position, the synchronization device with the links 1 and 19 may be a hindrance when entering the lower platform 7 in its drive position. If, on the other hand, the arrangement is used in which the handlebars are indicated by dash-dotted lines 6 and 22, the handlebars always remain below the lower platform 7, but require sufficient space there for their movements.
