Description

Die Erfindung betrifft einen Wagenheber für Kraftfahrzeuge der im Ober­begriff des Patentanspruchs 1 erläuterten Art.The invention relates to a jack for motor vehicles of the type explained in the preamble of claim 1.

Aus der GB-PS 12 27 715 ist ein Wagenheber für Kraftfahrzeuge der im Oberbegriff des Patentanspruchs 1 erläuterten Art bekannt.From GB-PS 12 27 715 a jack for motor vehicles of the type explained in the preamble of claim 1 is known.

Bei diesem Wagenheber besteht die Möglichkeit den etwa in der Mitte des Lastarmes angreifenden Stützarm leicht lösbar am Basisteil abzustützen, wodurch der Wagenheber in einfacher Weise auf eine Anfangshöhe einge­stellt werden kann, von der aus dann durch Drehung der Gewindespindel der Hubvorgang beginnen kann.With this jack there is the possibility of supporting the support arm, which engages approximately in the middle of the load arm, in a detachable manner on the base part, as a result of which the jack can be easily adjusted to an initial height, from which the lifting process can then begin by rotating the threaded spindle.

Der bakannte Wagenheber weist den Nachteil auf, daß er vollständig unter das Kraftfahrzeug geschoben werden muß, damit die Hubkurve des Last­kopfes der Kippbewegung des Kraftfahrzeuges folgen kann, wodurch die Zugänglichkeit der Gewindespindel, die unmittelbar am Boden liegt, schwierig ist.The known jack has the disadvantage that it has to be pushed completely under the motor vehicle so that the lifting curve of the load head can follow the tilting movement of the motor vehicle, which makes the threaded spindle, which is located directly on the ground, difficult to access.

Aus der GB-PS 13 22 426 ist eine veränderte Ausführungsform eines Wagenhebers für Kraftfahrzeuge gemäß dem Oberbegriff des Patentan­spruchs 1 bekannt, bei die Gelenkanordnung des Wagenhebers so ausgelegt ist, daß er seitlich außerhalb des Kraftfahrzeuges angesetzt werden kann. Durch eine etwas höhere Lage des Betätigungsendes der Gewindespindel ist die Bedienung erleichtert. Das Basisteil ist hierbei gelenkig mit einem Fußteil verbunden, in dem der Stützarm in zwei unterschiedlichen Stellungen abstützbar ist und dieses Fußteil ermöglicht dem Lastkopf eine Hubkurve, die durch Hochziehen des Basisteiles gegen­über dem Fußteil etwa dem Kippen des Kraftfahrzeuges folgen kann. Dadurch wird jedoch die Standsicherheit des Wagenhebers gegenüber der Auflage mit dem gesamten Basisteil erheblich verringert.From GB-PS 13 22 426 a modified embodiment of a jack for motor vehicles according to the preamble of claim 1 is known, in which the articulated arrangement of the jack is designed so that it can be attached laterally outside the motor vehicle. Operation is facilitated by a slightly higher position of the actuating end of the threaded spindle. The base part is articulated to a foot part, in which the support arm can be supported in two different positions, and this foot part enables the load head to have a lifting curve, which can roughly follow the tilting of the motor vehicle by pulling up the base part relative to the foot part. However, this significantly reduces the stability of the jack compared to the support with the entire base part.

Die Aufgabe der Erfindung ist es einen Wagenheber für Kraftfahrzeuge der im Oberbegriff des Patentanspruchs 1 erläuterten Art derart zu ver­bessern, daß eine einfachere Handhabung des Wagenhebers bei verbesser­ter Funktionsweise erzielt wird.The object of the invention is to improve a jack for motor vehicles of the type explained in the preamble of claim 1 in such a way that easier handling of the jack is achieved with improved functionality.

Gemäß der Erfindung wird diese Aufgabe gelöst, indem ein Wagenheber für Kraftfahrzeuge gemäß dem Oberbegriff des Patentanspruchs 1 die im Kennzeichenteil des Patentanspruchs 1 aufgezeigten Merkmale aufweist.According to the invention, this object is achieved in that a jack for motor vehicles according to the preamble of claim 1 has the features shown in the characterizing part of claim 1.

Dadurch, daß das Basisteil einen U-förmigen Querschnitt aufweist und in den vertikalen Seitenwänden liegende, leicht S-förmige Kulissenschlitze aufweist, in denen die Bolzen des Mutterstückes geführt sind, wird eine Hubkurve des Lastkopfes erzielt, die bei aufliegendem Basisteil der auf­tretenden Kippbewegung des Kraftfahrzeuges entspricht und damit für eine hohe Standfestifkeit und Funktionssicherheit sorgt.Characterized in that the base part has a U-shaped cross-section and has in the vertical side walls, slightly S-shaped link slots, in which the bolts of the nut piece are guided, a lifting curve of the load head is achieved which, when the base part rests, the tilting movement of the motor vehicle that occurs corresponds and thus ensures high stability and functional reliability.

In den weiteren Ansprüchen sind zweckmässige Ausgestaltungen der Er­findung näher erläutert.In the further claims, expedient embodiments of the invention are explained in more detail.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung näher er­läutert.In the drawing, an embodiment of the invention is explained in more detail.

  • Fig. 3 is a side view of the jack in the direction of arrow III in Fig. 1;
  • Figures 4a to 4d vertical sections along the lines aa, bb, cc and dd in Fig. 1 and
  • Fig. 5 is a side view of the jack 5 with indicated construction of the lifting curve of the load head.

Der in den Figuren 1 bis 3 gezeigte Wagenheber besteht im Wesentlichen aus einem Basisteil 1 mit einem tiefen U-förmigen Querschnitt, der ver­tikale Seitenwände 2 und 3 mit sich anschließenden nach außen abge­winkelten Verstärkungsflanschen 4 und 5 aufweist.The car jack shown in FIGS. 1 to 3 essentially consists of a base part 1 with a deep U-shaped cross section, which has vertical side walls 2 and 3 with adjoining outwardly angled reinforcing flanges 4 and 5.

Zwischen den Seitenwänden 2 und 3 ist eine Gewindespindel 7 angeordnet, deren lastseitiges Ende über ein Spindellager 8 in einem Lagerbock 9 abgestützt ist und deren betätigungsseitiges Ende über ein Mutterstück 10 und sich hierzu senkrecht erstreckende Bolzen 11 in liegenden, leicht S-förmigen Kulissenschlitzen 12 abgestützt ist. Das freie Ende der Ge­windespindel 7 weist einen Betätigungsring 13 auf.Between the side walls 2 and 3, a threaded spindle 7 is arranged, the load-side end of which is supported by a spindle bearing 8 in a bearing block 9 and the actuation-side end of which is supported by a nut piece 10 and bolts 11 extending perpendicular thereto in lying, slightly S-shaped link slots 12 is. The free end of the threaded spindle 7 has an actuating ring 13.

Ein freitragender Lastarm 14 stützt sich mit seinem gabelförmigen Ende 15 an den Bolzen 11 am Mutterstück 10 ab und trägt an seinem freien Ende einen Lastkopf 16, der der Aufnahme am Kraftfahrzeug angepaßt ist. Etwa in der Mitte des Lastarmes 14 greift eine Stützarm 17 über einen Bolzen 18 gelenkig an. Das andere Ende des Stützarmes 17 ist über einen Bolzen 19 in den vertikalen Seitenwänden 2 und 3 des Basisteiles 1 abge­stützt.A cantilevered load arm 14 is supported with its fork-shaped end 15 on the bolt 11 on the nut piece 10 and carries at its free end a load head 16 which is adapted to the receptacle on the motor vehicle. Approximately in the middle of the load arm 14, a support arm 17 hinges on a pin 18. The other end of the support arm 17 is supported by a bolt 19 in the vertical side walls 2 and 3 of the base part 1.

Der Lastarm 14 und der Stützarm 17 sind hierbei, wie am besten aus den Figuren 4a bis 4d zu ersehen ist, als steife, U-förmige Querschnitte aufweisende Bauteile ausgeführt. Vorzugsweise sind sowohl das Basisteil 1 als auch der Lagerbock 9 sowie der Lastarm 14 und der Stützarm 17 als stabile Blechpreßteile ausgebildet. Um eine günstigere Höhenlage des Betätigungsringes 13 der Gewindespindel 7 zu erreichen, ist das betä­tigungsseitige Ende des Basisteiles 1 über einen Stützfuß 20 etwas vom Boden abgehoben.The load arm 14 and the support arm 17 are, as can best be seen from FIGS. 4a to 4d, designed as rigid, U-shaped cross-sections. Preferably, both the base part 1 and the bearing block 9 as well as the load arm 14 and the support arm 17 are designed as stable sheet-metal pressed parts. In order to achieve a more favorable height position of the actuating ring 13 of the threaded spindle 7, the actuating end of the base part 1 is lifted somewhat off the floor by means of a support leg 20.

In Zusammenhang mit Fig. 5 wird nunmehr die Funktionsweise des Wagen­hebers gemäß der Erfindung erläutert.The operation of the jack according to the invention will now be explained in connection with FIG. 5.

Der Wagenheber wird mit seinem horizontalen Basisteil 1 und dem Fuß 20 auf dem Boden aufgelegt und das untere gabelförmige Ende des Lastarmes 14 auf die Bolzen 11 am Mutterstück 10 aufgesetzt. Damit kann bei nicht völlig in unterster Endstellung befindlichem Mutterstück 10 eine An­fangshöhe des Lastkopfes 16 eingestellt werden, von der aus die Betä­tigung beginnt. Dadurch kann ein umständliches und zeitraubendes Drehen der Gewindespindel 7 erheblich verringert werden.The jack is placed on the floor with its horizontal base part 1 and the foot 20 and the lower fork-shaped end of the load arm 14 is placed on the bolts 11 on the nut piece 10. Thus, when the nut piece 10 is not completely in the lowest end position, an initial height of the load head 16 can be set, from which the actuation begins. As a result, the cumbersome and time-consuming turning of the threaded spindle 7 can be considerably reduced.

Wird nun über den Betätigungsring 13 die Gewindespindel 7 gedreht, so bewegt sich das Mutterstück 10 entlang der leicht S-förmigen Kulissen­schlitze 12 in Richtung auf das Spindellager 8 zu und drängt hierdurch den Lastarm 14 und den Stützarm 17 über die gelenkige Vebindung mit dem Bolzen 18 nach oben. Der Lastkopf 16 bewegt sich hierbei entlang der durch Konstruktionsschritte angedeuteten Hubkurve, die eindeutig einer Kippbewegung des Kraftfahrzeuges folgt.If the threaded spindle 7 is now rotated via the actuating ring 13, the nut piece 10 moves along the slightly S-shaped link slots 12 in the direction of the spindle bearing 8 and thereby urges the load arm 14 and the support arm 17 via the articulated connection with the bolt 18 up. The load head 16 moves here along the stroke curve indicated by construction steps, which clearly follows a tilting movement of the motor vehicle.

Dadurch ist gewährleistet, daß trotz der zwangsläufigen Kippbewegung des angehobenen Kraftfahrzeuges der Wagenheber nach wie vor mit seinem vollen Basisteil 1 auf dem Boden aufliegen kann, wodurch eine erheblich günstigere Standfestigkeit als bei den bekannten Ausführungs­formen erzielt wird.This ensures that, despite the inevitable tilting movement of the raised motor vehicle, the jack can still rest on the floor with its full base part 1, thereby achieving a considerably more favorable stability than in the known embodiments.

Wird nach beendetem Reifenwechseln und dergleichen das Kraftfahrzeug wieder abgesenkt, so braucht man die Gewindespindel nur solange zu betätigen, bis der Lastkopf 16 vom Kraftfahrzeug freikommt. Zieht man nun den Wagenheber unter dem Kraftfahrzeug hervor, so kann man durch leichtes Anheben des Lastarmes 14 diesen mit seinem gabelförmigen Ende von den Bolzen 11 am Mutterstück 10 ausrasten, wodurch der Wagenheber voll zusammengeklappt werden kann, ohne daß hierfür das Mutterstück 10 in seine äußerste Endlage gedreht werden muß. Bei einer neuerlichen Benutzung des Wagenhebers kann dann durch Einhängen des gabelförmigen Endes 15 des Lastarmes 14 sofort die Angangshöhe, die man für das Kraft­fahrzeug benötigt, eingestellt werden.If the motor vehicle is lowered again after the tire change and the like have been completed, the threaded spindle need only be actuated until the load head 16 is released from the motor vehicle. If you now pull the jack out from under the motor vehicle, you can disengage it with its fork-shaped end from the bolts 11 on the nut piece 10 by slightly lifting the load arm 14, as a result of which the jack can be fully folded without the nut piece 10 being in its outermost position End position must be turned. When the jack is used again, the initial height required for the motor vehicle can then be set immediately by hooking in the fork-shaped end 15 of the load arm 14.
