Description

Die Erfindung bezieht sich auf einen Wagenheber mit mindestens einem Standbein und einem daran höhenbeweglich angeschlossenen Tragarm, der mittels einer Stellvorrichtung in seiner Lage veränderbar ist und im Bereich seines äußeren freien Endes eine Tragplatte mit einer Vertiefung und einer sich daran ausschließenden Abstützfläche aufweist, die mittels einer horizontal verlaufenden Achse über mindestens einer aus einem Tragplattenteil einteilig ausgeformten Öse an den Tragarm schwenkbar angeschlossen ist.The invention relates to a jack with at least one main leg and a support arm connected to it in a vertically movable manner, the position of which can be changed by means of an adjusting device and in the region of its outer free end a support plate with a depression and an adjoining support surface, which by means of a horizontally extending axis is pivotally connected to the support arm via at least one eyelet formed in one piece from a support plate part.

Nach der DE-B 2 801 735 oder der DE-U 8 522 952 sind bereits Wagenheber der eingangs aufgeführten Art bekannt. Nachteilig bei diesen Wagenhebern können bei sehr starker einseitiger Belastung die den Bolzen bzw. die Achse umgebenden Laschen aufgebogen werden. Eine darartige einseitige Belastung tritt insbesondere dann auf, wenn beispielsweise an einer ansteigenden Straße der Wagenheber mit Bezug auf das Fahrzeug schräg aufgestellt werden muß. Wenn sich die Tragplatte aufgrund des Aufbiegens der Öse vom Tragarm löst, besteht die Gefahr, daß das angehobene Fahrzeug zurückkippt, wodurch eine große Verletzungsgefahr für den Bediener hervorgerufen wird.According to DE-B 2 801 735 or DE-U 8 522 952, jacks of the type mentioned at the outset are already known. A disadvantage of these jacks, the tabs surrounding the bolt or the axle can be bent open in the event of very strong one-sided loading. Such a one-sided load occurs in particular when, for example, the jack must be set up obliquely with respect to the vehicle on a rising road. If the support plate detaches from the support arm due to the bending of the eyelet, there is a risk that the lifted vehicle will tip back, causing a great risk of injury to the operator.

Der Erfindung liegt die Aufgabe zugrunde, die am Tragarm bewegliche angeordnete Tragplatte derart auszubilden und anzuordnen, daß auch bei einseitiger Belastung der Tragplatte keine Beschädigung der Tragplatte bzw. der Verbindungen zwischen Tragplatte und Tragarm auftreten können. Diese Aufgabe ist durch die im kennzeichnenden Teil des Anspruches 1 aufgeführten Merkmale gelöst. Durch diese Ausbildung erhält man eine sichere Aufnahme der Achse, so daß auch bei einseitiger Belastung der Tragplatte, insbesondere bei Schrägstellung des Wagenhebers, kein Aushebeln der Achse aus der Öse erfolgt, da diese sich nunmehr nicht mehr aufbiegen läßt. Dies wird insbesondere dadurch erreicht, daß die Enden der Ösen mit den Teilen der Tragplatte auch nach Herausstanzen einteilig verbunden bleiben und somit zwischen den Enden der Ösen und der Tragplatte eine dauerhafte Verbindung sichergestellt ist.The invention has for its object to design and arrange the support plate movable on the support arm in such a way that no damage to the support plate or the connections between the support plate and the support arm can occur even when the support plate is subjected to one-sided loading. This object is by the features listed in the characterizing part of claim 1 solved. This design provides a secure mounting of the axle, so that even with one-sided loading of the support plate, especially when the jack is tilted, the axle is not levered out of the eyelet, since it can no longer be bent open. This is achieved in particular in that the ends of the eyelets remain in one piece with the parts of the support plate even after punching out, and thus a permanent connection is ensured between the ends of the eyelets and the support plate.

Durch die vorteilhafte Ausgestaltung der die Achse aufnehmenden Ösen lassen sich Tragplatte und Achse auch als Baugruppe gemäß Anspruch 2 vormontieren und dann die Baugruppe mit dem Tragarm fest verbinden, wozu die Achse beispielsweise stumpf an Schenkeln des Tragarmes angeschweißt wird.Due to the advantageous design of the eyelets receiving the support plate and axle can also be preassembled as an assembly according to claim 2 and then firmly connect the assembly to the support arm, for which purpose the axle is butt welded to legs of the support arm, for example.

In weiterer Ausgestaltung der Erfindung ist es vorteilhaft, daß die mit Abstand zueinander angeordneten Ösen nach der Montage der Tragplatte am Tragarm gegen parallel verlaufende Schenkel des Tragarmes zur Anlage kommen, so daß eine Seitenverstellung der Tragplatte verhindert wird. Hierzu ist es ferner vorteilhaft, daß die Achse alternativ zur Aufnahme der Ösen rillenförmige Vertiefungen aufweist, die ein Verschieben der Tragplatte auf der Achse verhindern. Außerdem ist es vorteilhaft, daß die Ösen an der Unterseite der Tragplatte angeordnet sind, so daß eine plane Auflagefläche an der Tragplatte gewährleistet ist.In a further embodiment of the invention, it is advantageous that the eyelets, which are arranged at a distance from one another, come into contact after mounting of the support plate on the support arm against parallel legs of the support arm, so that lateral adjustment of the support plate is prevented. For this purpose, it is also advantageous that the axle has, as an alternative to receiving the eyelets, groove-shaped depressions which prevent the support plate from being displaced on the axle. It is also advantageous that the eyelets are arranged on the underside of the support plate, so that a flat contact surface is ensured on the support plate.

Nachfolgend ist die Erfindung anhand eines in der Zeichnung schematisch dargestellten Ausführungsbeispiels näher erläutert. Es zeigen:

A perspective view of the front end of the support plate and the support arm in the view from below

In der Zeichnung ist mit 10 ein Wagenheber bezeichnet, der aus einem Standbein 12 und an diesem mittels eines Gelenkbolzens 14 vertikal schwenkbar angeschlossenen Tragarm 16 besteht. Das Standbein 12 weist an seinem unteren Ende eine Abstellplatte 18 mit einem Wälzfuß 20 auf. Mit der Abstellplatte 18 wird der Wagenheber 10 beim Ansetzen am Kraftfahrzeug auf dem Boden abgestellt. An dem Wälzfuß 20 ist ferner eine im Winkel zur Anstellplatte 18 angeordnete Standplatte 22 vorgesehen.In the drawing, 10 denotes a jack, which consists of a support leg 12 and a support arm 16 which is connected to it by means of a pivot pin 14 and which can be pivoted vertically. The supporting leg 12 has a storage plate 18 with a roller foot 20 at its lower end. With the parking plate 18, the jack 10 is parked on the floor when attached to the motor vehicle. A stand plate 22 arranged at an angle to the positioning plate 18 is also provided on the roller foot 20.

Am oberen Ende des beispielsweise U-förmig ausgebildeten Standbeins 12 befindet sich eine als Gewindespindel 27 ausgebildete Stellvorrichtung 26, die mit Hilfe einer Spindelmutter 28 schwenkbar gelagert ist. Die Spindelmutter 28 weist beidseitig Zapfen 30 auf, mittels der die Spindelmutter 28 in Seitenwangen 32 des Standbeines 12 aufgenommen ist.At the upper end of the U-shaped leg 12, for example, there is an adjusting device 26 designed as a threaded spindle 27, which is pivotably mounted with the aid of a spindle nut 28. The spindle nut 28 has pins 30 on both sides, by means of which the spindle nut 28 is received in side cheeks 32 of the supporting leg 12.

Am unteren Ende der Gewindespindel 27 ist der Tragarm 16 über ein nicht näher dargestelltes Spindelwiderlager angelenkt, z. B. ein Wälzlager, dessen eine Lagerscheibe von der Gewindespindel 27 beaufschlagt wird und dessen andere Lagerscheibe Zapfen 34 aufweist, die in den Seitenwangen 54 des U-förmigen Tragarmes 16 eingreifen.At the lower end of the threaded spindle 27, the support arm 16 is articulated via a spindle abutment, not shown, for. B. a roller bearing, one bearing disc is acted upon by the threaded spindle 27 and the other bearing disc has pins 34 which engage in the side walls 54 of the U-shaped support arm 16.

Wie aus Fig. 1 hervorgeht, ist der Tragarm 16 über den Gelenkbolzen 14 mit dem Standbein 12 gelenkig verbunden und führt entsprechend der Stellvorrichtung 26 Schwenkbewegungen relativ zum Standbein 12 aus.As can be seen from FIG. 1, the support arm 16 is connected in an articulated manner to the support leg 12 via the hinge pin 14 and, according to the adjusting device 26, carries out pivoting movements relative to the support leg 12.

Am freien Ende des Tragarmes 16 befindet sich eine Tragplatte 40, mit der der Wagenheber 10 an einen Fahrzeugboden eines Kraftfahrzeuges angesetzt werden kann. Die Tragplatte 40 hat eine Vertiefung 42 zur Aufnahme einer Schwellernaht eines in der Zeichnung nicht dargestellten Fahrzeugbodens. An die Vertiefung 42 der Tragplatte 40 schließt sich eine Abstützfläche 44 an, die sich derart an einen Fahrzeugboden anlegen kann, daß die Schwellernaht des Kraftfahrzeuges von der Tragplatte 40 frei bleibt. Zur Verringerung der Flächenpressung am Fahrzeugboden ist die Abstützfläche so groß wie möglich bemessen.At the free end of the support arm 16 there is a support plate 40 with which the jack 10 can be attached to a vehicle floor of a motor vehicle. The support plate 40 has a recess 42 for receiving a sill seam of a vehicle floor, not shown in the drawing. A support surface 44 adjoins the recess 42 of the support plate 40, which can lie against a vehicle floor in such a way that the sill seam of the motor vehicle remains free from the support plate 40. To reduce the surface pressure on the vehicle floor, the support surface is dimensioned as large as possible.

Wie insbesondere aus Fig. 2 hervorgeht, sind in der Abstützfläche 44 der Tragplatte 40 zwei mit Abstand zueinander angeordnete Ösen 50 eingestanzt, wobei die Enden der Ösen 50 mit Teilen der Tragplatte einteilig verbunden bleiben. Die an der Unterseite der Abstützfläche 44 vorgesehenen Ösen 50 dienen zur Aufnahme einer Achse bzw. eines Bolzens 52. Die Tragplatte 40 sowie die Achse 52 können als vormontierbare Baugruppe ausgebildet sein, so daß sich diese dann ohne weiteres an das vordere Ende des Tragarmes 16 anschließen läßt. Eine feste Verbindung zwischen der Tragplatte 40 und dem vorderen Ende des Tragarmes 16 erhält man dadurch, daß die Achse 52 mit Seitenwangen 54 des Tragarmes 16 stumpf verschweißt sind. Der Abstand zwischen den innenliegenden Flächen der Ösen 50 ist etwas größer als der Abstand zwischen den außenliegenden Flächen der Seitenwangen 54, so daß bei der Verbindung der Tragplatte 40 mit dem vorderen Ende des Tragarmes 16 die innenliegenden Flächen der Ösen 50 gegen die außenliegenden Flächen der Seitenwangen 54 zur Anlage kommen und somit eine Verschiebung der Tragplatte 40 auf dem Bolzen bzw. der Achse 52 verhindern. Eine Sicherung in Axialrichtung der Tragplatte 40 ist auch dadurch möglich, daß in dem Bolzen rillenförmige Vertiefungen vorgesehen werden, in die die Ösen 50 einrasten können. Hierzu werden nach Einführung der Achse 52 in die Ösen 50 die Ösen so weit zusammengedrückt, bis sie in die vorgesehenen Rillen eingreifen.As can be seen in particular from FIG. 2, two eyelets 50 arranged at a distance from one another are punched into the support surface 44 of the support plate 40, the ends of the eyelets 50 remaining connected in one piece to parts of the support plate. The eyelets 50 provided on the underside of the support surface 44 serve to receive an axle or a bolt 52. The support plate 40 and the axle 52 can be designed as a preassembled subassembly, so that these then easily connect to the front end of the support arm 16 leaves. A firm connection between the support plate 40 and the front end of the support arm 16 is obtained in that the axis 52 is butt welded to side walls 54 of the support arm 16. The distance between the inner surfaces of the eyelets 50 is slightly larger than the distance between the outer surfaces of the side cheeks 54, so that when the support plate 40 is connected to the front end of the support arm 16, the inner surfaces of the eyelets 50 against the outer surfaces of the side cheeks 54 come to rest and thus prevent displacement of the support plate 40 on the bolt or the axis 52. Securing in the axial direction of the support plate 40 is also possible in that groove-shaped depressions are provided in the bolt, into which the eyelets 50 can snap. For this purpose, after inserting the axis 52 into the eyelets 50, the eyelets are pressed together until they engage in the grooves provided.
