Definitions
- the invention relates to a lifting platform for motor vehicles with at least one supporting element acting on the underside of the vehicle, which in turn is supported on a base by means of a scissor-type frame, the scissor-type frame having at least two intersecting lower and two intersecting upper scissor levers, each of which has a first at the crossing points Pivot bearings are connected to one another and the lower scissor levers in their upper region are each connected to the lower regions of the upper scissor lever via second pivot bearings.
- Such scissor lifts are known in numerous embodiments.
- two support elements are used, each of which has its own scissor-type frame and is arranged next to one another in such a way that it engages under the vehicle on both sides.
- the aim is to minimize the size of the support elements. It is therefore known in the sense of a particularly narrow construction, the upper and lower scissor levers on their common terminal pivot bearing not to be arranged next to each other but in alignment one above the other.
- the storage takes place via laterally welded tabs, which protrude in the longitudinal and transverse directions of the scissor lever, so that the upper scissor lever lies flat on the lower one when the lifting platform is folded.
- the support elements then have a relatively large floor protrusion when the lift is lowered, which can lead to damage when driven over by lowered vehicles or by vehicles with the spoiler pulled down low. That is why such lifts must either be embedded in the floor or equipped with long ramps for ascending and descending.
- the object of the present invention is to improve the known lifting platforms in such a way that on the one hand they manage with narrow supporting elements, and on the other hand they are characterized by a small floor protrusion when the lifting platform is lowered.
- the upper or the lower of two pivotally connected scissor levers has a slot running in the longitudinal direction of the scissor lever, the other Scissor lever is open and that this other scissor lever is at least predominantly immersed in this slit in the lowered position of the lifting platform.
- the lower scissor levers are slotted, the upper scissor levers can be fully immersed in the lower scissor levers when the lifting platform is lowered and do not require any overall height.
- the lifting platform according to the invention thus combines the advantages of the scissor frames with scissor levers arranged one above the other and with side by side, without having to accept their respective disadvantages. Last but not least, it is also characterized by low manufacturing costs, because there is no need to weld special tabs for the swivel bearings.
- the scissor levers which should have the slot mentioned, can have any cross-sectional shape.
- the scissor levers can have any cross-sectional shape.
- the immersing scissor levers can be upright flat bars.
- the pivot bearing connecting the lower and the upper scissor lever expediently consists of a bolt which is inserted in the two opposite sides of the slot and crosses the other scissor lever in the intermediate space. This results in a particularly stable bearing with little bending stress on the bolt.
- a particularly advantageous development of the invention consists in that the scissors levers having the slot have lateral cutouts in their central region for the aforementioned first pivot bearings of the upper scissor lever. This enables the scissors levers that belong together to move together completely without the pivot bearing being in the way. The same measure is also recommended if the upper scissor levers have the usual lateral articulation points for the introduction of the lifting force. These cutouts are expediently arranged only on one side of the slot.
- reinforcements are provided on the side opposite the cutouts, for example by welded flat iron.
- the part of the lift shown which is only intended to support one side of the vehicle, consists of a base plate 1, one mounted thereon Scissor frame 2, which can be raised or lowered via a lifting element in the form of two hydraulic cylinders 3 connected in parallel, and a support element in the form of a plate 4 mounted on the top of the scissor frame.
- Short, pivotable plates 5 are at the front and rear ends of the plate 4 and 6 articulated to facilitate the vehicle to be driven over.
- the scissor-type frame 2 is initially only described for the scissor levers located at the front in the drawing. Accordingly, two intersecting lower scissor levers 7a and 7b are provided, of which one scissor lever 7b is articulated to a fixed bearing of the base plate 1, while the other scissor lever 7b is also guided horizontally on the base plate in addition to its pivoting movement. Both scissor levers 7a and 7b are connected to one another at their crossing point via a pivot bearing 8, while at the upper ends they each carry further pivot bearings 9 and 10, to which upper scissor levers 11a and 11b are articulated. They run parallel to the lower scissor levers and are connected to one another at their crossing point via a pivot bearing 12. At their upper ends, the upper scissor levers carry the support plate 4, with the same bearing or guiding principle as shown on the base plate 1.
- the entire scissor-type frame is driven by two cylinder-piston units 3 which are articulated at one end of the base plate 1 and act on the opposite upper scissor-type levers 11a, specifically via articulation points 13.
- Spreading lever 14 according to the utility model 92 05 900 support the lifting movement from the folded state of the scissor lever until the lifting element has been sufficiently pivoted out of the lower dead position.
- the lower scissor levers 7a and 7b have corresponding recesses 27a to 27d on the inside and outside sides of the U-profile, each of which is open at the top.
- the inner scissor levers 7b and 7c have further recesses 28b and 28c on their inner sides for the articulation points 13 of the lifting member.
- the leg regions of the U-profile lying opposite these recesses are each stiffened by a welded-on flat iron or the like.

Abstract
Description
Die Erfindung betrifft eine Hebebühne für Kraftfahrzeuge mit zumindest einem an der Fahrzeugunterseite angreifenden Tragelement, das sich seinerseits über ein Scherengestell an einer Basis abstützt, wobei das Scherengestell zumindest zwei sich kreuzende untere und zwei sich kreuzende obere Scherenhebel aufweist, die an den Kreuzungspunkten jeweils über erste Schwenklager miteinander verbunden sind und wobei die unteren Scherenhebel in ihrem oberen Bereich jeweils über zweite Schwenklager mit den unteren Bereichen der oberen Scherenhebel verbunden sind.The invention relates to a lifting platform for motor vehicles with at least one supporting element acting on the underside of the vehicle, which in turn is supported on a base by means of a scissor-type frame, the scissor-type frame having at least two intersecting lower and two intersecting upper scissor levers, each of which has a first at the crossing points Pivot bearings are connected to one another and the lower scissor levers in their upper region are each connected to the lower regions of the upper scissor lever via second pivot bearings.
Derartige Scheren-Hebebühnen sind in zahlreichen Ausführungsformen bekannt. Im allgemeinen wird dabei mit zwei Tragelementen gearbeitet, die jeweils über ein eigenes Scherengestell verfügen und derart nebeneinander angeordnet sind, daß sie das Fahrzeug an beiden Seiten untergreifen.Such scissor lifts are known in numerous embodiments. In general, two support elements are used, each of which has its own scissor-type frame and is arranged next to one another in such a way that it engages under the vehicle on both sides.
Da der von den Tragelementen abgedeckte Bereich des Fahrzeugbodens unzugänglich für Reparaturarbeiten ist, strebt man eine möglichst geringe Größe für die Tragelemente an. Es ist deshalb im Sinne einer besonders schmalen Bauweise bekannt, die oberen und unteren Scherenhebel an ihrem gemeinsamen endständigen Schwenklager nicht nebeneinander sondern fluchtend übereinander anzuordnen. Die Lagerung erfolgt dabei über seitlich angeschweißte Laschen, die in Längs- und Querrichtung der Scherenhebel überstehen, so daß im zusammengeklappten Zustand der Hebebühne der obere Scherenhebel plan auf dem unteren aufliegt. Allerdings haben die Tragelemente dann bei heruntergelassener Hebebühne einen relativ großen Boden-Überstand, der beim Überfahren durch tiefergelegte Fahrzeuge oder durch Fahrzeuge mit tief heruntergezogenem Spoiler zu Beschädigungen führen kann. Deshalb müssen solche Hebebühnen entweder in den Boden eingelassen oder mit langen Rampen zum Auf- und Abfahren bestückt werden.Since the area of the vehicle floor covered by the support elements is inaccessible for repair work, the aim is to minimize the size of the support elements. It is therefore known in the sense of a particularly narrow construction, the upper and lower scissor levers on their common terminal pivot bearing not to be arranged next to each other but in alignment one above the other. The storage takes place via laterally welded tabs, which protrude in the longitudinal and transverse directions of the scissor lever, so that the upper scissor lever lies flat on the lower one when the lifting platform is folded. However, the support elements then have a relatively large floor protrusion when the lift is lowered, which can lead to damage when driven over by lowered vehicles or by vehicles with the spoiler pulled down low. That is why such lifts must either be embedded in the floor or equipped with long ramps for ascending and descending.
Wird statt dessen mit Scherengestellen gearbeitet, bei denen die oberen und unteren Scherenhebel nebeneinander angeordnet sind, erhält man zwar einen geringeren Bodenüberstand des Tragelementes, benötigt aber eine größere Baubreite. Außerdem müssen alle Schwenklager als Kraglager ausgebildet sein, was die Stabilität der Bühne beeinträchtigt.If, instead, you work with scissor frames in which the upper and lower scissor levers are arranged next to each other, you get a smaller floor protrusion of the support element, but you need a larger width. In addition, all swivel bearings must be designed as cantilever bearings, which affects the stability of the platform.
Hiervon ausgehend liegt die Aufgabe der vorliegenden Erfindung darin, die bekannten Hebebühnen dahingehend zu verbessern, daß sie einerseits mit schmalen Tragelementen auskommen, und sich andererseits durch geringen Bodenüberstand bei heruntergelassener Hebebühne auszeichnen.Proceeding from this, the object of the present invention is to improve the known lifting platforms in such a way that on the one hand they manage with narrow supporting elements, and on the other hand they are characterized by a small floor protrusion when the lifting platform is lowered.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß jeweils der obere oder der untere von zwei schwenkbar verbundenen Scherenhebeln einen in Längsrichtung des Scherenhebels laufenden Schlitz aufweist, der zum anderen Scherenhebel hin offen ist und daß dieser andere Scherenhebel in heruntergefahrener Stellung der Hebebühne zumindest überwiegend in diesen Schitz eintaucht. Werden also beispielsweise, was zweckmäßig ist, die unteren Scherenhebel geschlitzt, so können die oberen Scherenhebel beim Herunterfahren der Hebebühne in die unteren Scherenhebel vollständig eintauchen und benötigen keinerlei Bauhöhe. Die erfindungsgemäße Hebebühne vereinigt somit die Vorteile der Scherengestelle mit übereinander und mit nebeneinander angeordneten Scherenhebeln, ohne deren jeweiligen Nachteile in Kauf nehmen zu müssen. Nicht zuletzt zeichnet sie sich auch durch günstige Fertigungskosten aus, weil auf das Anschweißen spezieller Laschen für die Schwenklager verzichtet werden kann.This object is achieved in that the upper or the lower of two pivotally connected scissor levers has a slot running in the longitudinal direction of the scissor lever, the other Scissor lever is open and that this other scissor lever is at least predominantly immersed in this slit in the lowered position of the lifting platform. If, for example, which is expedient, the lower scissor levers are slotted, the upper scissor levers can be fully immersed in the lower scissor levers when the lifting platform is lowered and do not require any overall height. The lifting platform according to the invention thus combines the advantages of the scissor frames with scissor levers arranged one above the other and with side by side, without having to accept their respective disadvantages. Last but not least, it is also characterized by low manufacturing costs, because there is no need to weld special tabs for the swivel bearings.
Grundsätzlich können die Scherenhebel, die den genannten Schlitz aufweisen sollen, beliebige Querschnittsform haben. Für eine kostengünstige Herstellung ist es aber besonders vorteilhaft, für diese Scherenhebel U-förmige Profileisen zu verwenden. Die eintauchenden Scherenhebel können in diesem Fall hochkant stehende Flachstäbe sein.Basically, the scissor levers, which should have the slot mentioned, can have any cross-sectional shape. For cost-effective production, however, it is particularly advantageous to use U-shaped profile irons for these scissor levers. In this case, the immersing scissor levers can be upright flat bars.
Das den unteren und den oberen Scherenhebel verbindende Schwenklager besteht zweckmäßig aus einem Bolzen, der in den beiden gegenüberliegenden Seiten des Schlitzes steckt und im Zwischenraum den anderen Scherenhebel durchquert. Man erhält dadurch eine besonders stabile Lagerung mit geringer Biegebeanspruchung des Bolzens.The pivot bearing connecting the lower and the upper scissor lever expediently consists of a bolt which is inserted in the two opposite sides of the slot and crosses the other scissor lever in the intermediate space. This results in a particularly stable bearing with little bending stress on the bolt.
Eine besonders vorteilhafte Weiterbildung der Erfindung besteht darin, daß die den Schlitz aufweisenden Scherenhebel in ihrem mittleren Bereich seitliche Aussparungen für die vorgenannten ersten Schwenklager der oberen Scherenhebel aufweisen. Dadurch ist ein vollständiges Zusammenfahren der zusammengehörenden Scherenhebel möglich, ohne daß das Schwenklager im Weg ist. Die gleiche Maßnahme empfiehlt sich auch dann, wenn die oberen Scherenhebel die üblichen seitlichen Anlenkpunkte für die Einleitung der Hubkraft aufweisen. Zweckmäßig sind diese Aussparungen nur an einer Seite des Schlitzes angeordnet.A particularly advantageous development of the invention consists in that the scissors levers having the slot have lateral cutouts in their central region for the aforementioned first pivot bearings of the upper scissor lever. This enables the scissors levers that belong together to move together completely without the pivot bearing being in the way. The same measure is also recommended if the upper scissor levers have the usual lateral articulation points for the introduction of the lifting force. These cutouts are expediently arranged only on one side of the slot.
Damit die Scherenhebel durch die genannten Aussparungen nicht an Biegesteifigkeit verlieren, sind an der Seite, die den Aussparungen gegenüberliegt, Verstärkungen vorgesehen, etwa durch aufgeschweißte Flacheisen.So that the scissor levers do not lose bending rigidity due to the cutouts mentioned, reinforcements are provided on the side opposite the cutouts, for example by welded flat iron.

Gemäß Figur 1 besteht der dargestellte Teil der Hebebühne, der nur zur Abstützung der einen Fahrzeugseite gedacht ist, aus einer Grundplatte 1, einem darauf montierten Scherengestell 2, das über ein Huborgan in Form zweier parallelgeschalteter Hydraulikzylinder 3 hochgefahren bzw. abgesenkt werden kann, und aus einem an der Oberseite des Scherengestelles montierten Tragelement in Form einer Platte 4. Am vorderen und hinteren Ende der Platte 4 sind kurze, schwenkbare Platten 5 und 6 angelenkt, um das Überfahren durch das anzuhebende Fahrzeug zu erleichtern.According to Figure 1, the part of the lift shown, which is only intended to support one side of the vehicle, consists of a base plate 1, one mounted thereon Scissor
Das Scherengestell 2 wird zunächst nur für die in der Zeichnung vorn liegenden Scherenhebel beschrieben. Demnach sind zwei sich kreuzende untere Scherenhebel 7a und 7b vorgesehen, von denen der eine Scherenhebel 7b an einen ortsfesten Lager der Bodenplatte 1 angelenkt ist, während der andere Scherenhebel 7b zusätzlich zu seiner Schwenkbewegung auch horizontal verfahrbar an der Bodenplatte geführt ist. Beide Scherenhebel 7a und 7b sind an ihrem Kreuzungspunkt über ein Schwenklager 8 miteinander verbunden, während sie an den oberen Enden jeweils weitere Schwenklager 9 und 10 tragen, an denen obere Scherenhebel 11a und 11b angelenkt sind. Sie verlaufen parallel zu den unteren Scherenhebeln und sind an ihrem Kreuzungspunkt über ein Schwenklager 12 miteinander verbunden. An ihren oberen Enden tragen die oberen Scherenhebel die Tragplatte 4, und zwar mit dem gleichen Lagerungs- bzw. Führungsprinzip wie an der Grundplatte 1 gezeigt.The scissor-
Parallel hinter den beschriebenen Scherenhebeln befindet sich nochmal das gleiche Scherenhebelsystem, um die Tragplatte 4 gegenüber Kippkräften zu stabilisieren. Die Verbindung dieser Scherensysteme untereinander kann in verschiedener, an sich bekannter Weise erfolgen.Parallel to the scissor levers described is the same scissor lever system to stabilize the
Der Antrieb des gesamten Scherengestelles erfolgt durch zwei Zylinder-Kolben-Aggregate 3, die an einem Ende der Grundplatte 1 angelenkt sind und auf die gegenüberliegenden oberen Scherenhebel 11a einwirken, und zwar über Anlenkpunkte 13.The entire scissor-type frame is driven by two cylinder-
Spreizhebel 14 gemäß dem Gebrauchsmuster 92 05 900 unterstützen die Aushebebewegung aus dem zusammengeklappten Zustand der Scherenhebel, bis das Huborgan ausreichend aus der unteren Totlage herausgeschwenkt ist.Spreading
Wesentlich ist nun, daß die unteren Scherenhebel 7a bis 7d - vergleiche Figur 2 - als U-Profile mit nach oben offenem Schlitz 17a bis 17d ausgebildet sind und daß die oberen Scherenhebel 11a bis 11d als dazu fluchtende Rechteckprofile ausgebildet sind, die in diesen Schlitz hineinpassen, so daß sie bei heruntergefahrener Hebebühne praktisch vollkommen darin verschwinden.It is now essential that the lower scissor levers 7a to 7d - compare FIG. 2 - are designed as U-profiles with an
Damit dieses Eintauchen nicht durch die Schwenklager 12 zwischen den oberen Scherenhebeln an den oberen Scherenhebeln beeinträchtigt wird, haben die unteren Scherenhebel 7a und 7b an den innen bzw. außenliegenden Seiten des U-Profils entsprechende Aussparungen 27a bis 27d, die jeweils nach oben offen sind. Außerdem haben die innenliegenden Scherenhebel 7b und 7c an ihren innenliegenden Seiten weitere Aussparungen 28b und 28 c für die Anlenkpunkte 13 des Huborgans. Die gegenüber diesen Aussparungen liegenden Schenkelbereiche des U-Profils sind jeweils durch ein aufgeschweißtes Flacheisen oder dergleichen versteift.So that this immersion is not impaired by the
Der in Figur 3 gezeigte Querschnitt durch das Scherengestell zeigt die Scherenhebel im zusammengeklappten Zustand. Man sieht, daß die oberen Scherenhebel vollständig in die unteren Scherenhebel eingetaucht sind und keinerlei zusätzlichen Platzbedarf benötigen.The cross section shown in Figure 3 through the scissors frame shows the scissor lever in the folded state. It can be seen that the upper scissor levers are completely immersed in the lower scissor lever and do not require any additional space.
Selbstverständlich liegt es im Rahmen der Erfindung, die Anordnung umzukehren, also die geschlitzten Scherenhebel nach oben und die in die Schlitze eintauchenden Scherenhebel nach unten zu verlegen. Ebenfalls kann man anstelle der gezeigten U-Profile auch andere Querschnitte verwenden, die einen nach unten oder oben offenen Schlitz aufweisen.It is of course within the scope of the invention to reverse the arrangement, that is to say to move the slotted scissor levers upwards and the scissor levers immersing into the slots downwards. It is also possible to use other cross sections instead of the U profiles shown, which have a slot which is open at the top or at the bottom.
Schließlich liegt es auch im Rahmen der Erfindung, die Scherenhebel nicht mit einem beidseits begrenzten Schlitz auszubilden, sondernScherenhebel mit einem L-förmigen Profil zu verwenden, das zum anderen Scherenhebel hin offen ist, so daß der andere Scherenhebel in heruntergefahrener Stellung der Hebebühne in das L-Profil eintauchen kann. Man kann sich dies leicht anhand von Figur 2 vorstellen: dort könnten beispielsweise bei den außenliegenden Scherenhebeln 7a und 7d die jeweils außenliegenden Seitenwände und bei den anderen Scherenhebeln 7b und 7c die jeweils innenliegenden Seitenwände des U-Profils entfallen, wenn man an den Schwenklagern 9 und 10 eine fliegende Lagerung vorsieht. Stattdessen könnten auch die jeweils anderen Seitenwände der U-Profile entfallen, wenn man das Schwenklager 8 von der Seitenwand verlegt an die Unterseite der Profile, was gegebenenfalls auch bei den Schwenklagern 9 und 10 möglich wäre.Finally, it is also within the scope of the invention not to form the scissor levers with a slot limited on both sides, but to use scissor levers with an L-shaped profile which is open towards the other scissor lever, so that the other scissor lever in the L down position of the lifting platform Profile can dip. This can easily be imagined with reference to FIG. 2: there, for example, the outer side walls of the outer scissor levers 7a and 7d and the inner side walls of the U-profile for the
Zusammenfassend erhält man also durch die vorliegende Erfindung ein Scherensystem, das nicht nur schmal sondern auch äußerst flach baut und sich dabei durch hohe Stabilität auszeichnet. Es ist neben dem Einsatz in Reparatur-Werkstätten selbstverständlich auch als Hubvorrichtung in Mehrfach-Parksystemen geeignet.In summary, the present invention provides a scissor system that is not only narrow but also extremely flat and is characterized by high stability. In addition to its use in repair workshops, it is of course also suitable as a lifting device in multiple parking systems.
