Description

Die Erfindung betrifft eine ausziehbare Zugeinrichtung für Anhänger, welche in axialer Richtung ausgezogen, eingeschoben und ohne Werkzeug fest arretiert werden kann.The invention relates to an extendable towing device for trailers, which can be extended in the axial direction, pushed in and locked firmly without tools.

Eine lange Zugeinrichtung beeinflußt das Fahrverhalten eines Gespanns (Zugfahrzeug und Anhänger) positiv, insbesondere wenn schwer oder lang geladen wird. Desweiteren läßt sich ein Anhänger mit langer Zugeinrichtung leichter rückwärts rangieren. Andererseits beansprucht eine lange Zugeinrichtung viel Platz, hinderlich ist eine Zugdeichsel, insbesondere eine lange, wenn der Anhänger in einer Garage senkrecht an der Wand abgestellt werden soll.A long towing device has a positive effect on the handling of a combination (towing vehicle and trailer), especially when the load is heavy or long. Furthermore, a trailer with a long towing device is easier to reverse. On the other hand, a long towing device takes up a lot of space, and a drawbar is a hindrance, especially a long one, if the trailer is to be parked vertically against the wall in a garage.

Es ist bekannt, daß zur Erfüllung dieser Erfordernisse ein Zugeinrichtung ausgezogen, eingeschoben und fest arretiert werden muß. Richtlinien des TÜV schreiben vor, daß ausziehbare Zugeinrichtungen von Nicht-Fachpersonal fachgerecht verstellt werden können muß. Eine weitere TÜV Richtlinie besagt, daß Ausziehbare Zugeinrichtungen spielfrei arretiert werden müssen und deshalb auch keinen Lärm verursachen dürfen.It is known that to meet these requirements, a towing device must be pulled out, pushed in and locked firmly. TÜV guidelines stipulate that extendable towing devices must be able to be properly adjusted by non-professional personnel. Another TÜV guideline states that extendable towing devices must be locked without play and must therefore not cause any noise.

Bisherige ausziehbare Zugeinrichtungen werden weitgehend mit quer zum Zugrohr durchgesteckten Steckbolzen arretiert. Diese Art der Arretierung ist keine kraftschlüssige Verbindung und somit entstehen beim fahren Geräusche. Der weitaus größte Teil der in betracht kommenden Anhänger wird mit nicht ausziehbaren Zugeinrichtungen ausgerüstet.Previous extendable towing devices are mostly locked with pins that are inserted across the towing tube. This type of locking is not a force-locking connection and therefore creates noise when driving. The vast majority of the trailers under consideration are equipped with non-extendable towing devices.

Der Erfindung liegt die Aufgabe zugrunde, die Zugeinrichtung eines Anhängers so zu gestalten, daß diese ausgezogen, eingeschoben und an mehreren Arretierungsstellen fest gespannt werden kann. Des weiteren die Herstellungskosten wirtschaftlich vertretbar sind, daß das Verstellen schnell, mit wenigen Handgriffen und ohne Werkzeug von einem Laien fachgerecht durchgeführt werden kann und daß die Verbindung zum Innenrohr und Außenrohr im arretierten Zustand kraftschlüssig, ohne Spiel und somit geräuscharm ist.The invention is based on the task of designing the towing device of a trailer in such a way that it can be pulled out, pushed in and tightened at several locking points. Furthermore, the manufacturing costs are economically justifiable, that the adjustment can be carried out quickly, with a few simple steps and without tools by a layperson, and that the connection to the inner tube and outer tube in the locked state is force-locking, without play and therefore quiet.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß das Innenrohr im Außenrohr verschiebbar ist und mit der zur Zugeinrichtung gehöhrenden Hebelschraube mit einem Handgriff fest arretiert werden kann.This object is achieved according to the invention in that the inner tube can be moved in the outer tube and can be firmly locked in place with one hand using the lever screw belonging to the pulling device.

Die mit der Erfindung erzielten Vorteü$uiD£$tehen jiJ^tjfSßndere.dayn? daß je nach Art der Benutzung, die Zugeinrichtung schnell in der Länge verstellt werden kann bzw. ganz eingeschoben und der Anhänger in verhältnismäßig niedrigen Räumen z.B. Garage, senkrecht an der Wand abgestellt werden kann.The advantages achieved with the invention are that, depending on the type of use, the towing device can be quickly adjusted in length or completely retracted and the trailer can be parked vertically against the wall in relatively low rooms, e.g. garages.

Dadurch gekennzeichent, daß das Innenrohr axial verschiebbar ist und mit einer Hebelschraube 3 kraftschlüssig mit der Außenrohrbuchse arretiert werden kann.1. Extendable towing device for trailers which can be pulled out in the axial direction, pushed in and locked in place without tools. Characterized by the fact that the inner tube can be moved axially and can be locked into place with a lever screw 3 using a force fit to the outer tube bushing. 2. Ausziehbare Zugeinrichtung für Anhänger nach Anspruch 1 dadurch gekennzeichnet, daß die Hebelschraube 3 durch die Außenrohrbuchse 11 durchgesteckt werden kann und somit das Innenrohr 9 beim eindrehen der Hebelschraube 3 in die an der gegenüberliegenden Seite der Außenrohrbuchse 11 angeschweißten Kronenmutter 10, an die Außenrohrbuchse 11 fest und kraftschlüussig angepresst wird.2. Extendable towing device for trailers according to claim 1, characterized in that the lever screw 3 can be pushed through the outer tube bushing 11 and thus the inner tube 9 is pressed firmly and force-fittingly onto the outer tube bushing 11 when the lever screw 3 is screwed into the castle nut 10 welded to the opposite side of the outer tube bushing 11. 3.Ausziehbare Zugeinrichtung für Anhänger nach Anspruch 1 und 2 dadurch gekennzeichnet,daß die vordere Außenrohrbuchse 11 um 1° axial nach hinten unten abhängend zwischen die beiden U-Profile 6 eingeschweißt ist ,so daß sich das Innenrohr 9, im festgezogenen Zustand, auf die Außenrohrbuchse 12, welche zentriert zwischen den beiden U-Profilen 6 eingeschweißt ist, aufpresst.3.
