Abstract

The tow device can be drawn out axially and pushed in and locked without tools. The inner tube (9) is axially displaceable and can be locked in force-locking engagement with the outer tube socket (11) by a lever screw (3). The lever screw can be pushed through the outer tube socket and when turned the inner tube is pressed firmly against the outer tube socket. The front outer tube socket is welded between the two U-profiled sections (6) hanging down and back axially by 1 deg so that in the fixed state the inner tube is pressed on the outer tube socket which is centred between the two profiles.

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 pulling device for trailers, which is in the axial direction can be pulled out, pushed in and locked in place 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 influences the driving behavior of a team (towing vehicle and Trailer) positive, especially if the load is heavy or long. Furthermore, one can Maneuver trailers with long drawbars more easily backwards. On the other hand, one claims long drawbar means a lot of space, a drawbar is a hindrance, especially a long one when the Trailer in a garage to be parked vertically on the wall.

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 a pulling device is pulled out to meet these requirements, inserted and firmly locked. TÜV guidelines stipulate that extendable Pulling devices must be able to be adjusted professionally by non-specialist personnel. Another TÜV directive states that pull-out pulling devices must be locked without play and therefore must 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.Existing pull-out pulling devices are largely used transversely to the draw tube inserted plug pins locked. This type of locking is not a positive one Connection and thus noises arise when driving. The vast majority of that is under consideration coming trailers will be equipped with pull-out devices that cannot be pulled out.

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 has for its object to design the traction device of a trailer so that these are pulled out, inserted and tightly tensioned at several locking points can. Furthermore, the manufacturing costs are economically justifiable that the adjustment quickly, professionally carried out by a layperson in a few simple steps and without tools can and that the connection to the inner tube and outer tube in the locked state non-positive, without play and therefore low noise.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß das Innenrohr im Außenrohr verschiebbar ist und mit der zur Zugeinrichtung gehörenden Hebelschraube mit einem Handgriff fest arretiert werden kann. This object is achieved in that the inner tube in the outer tube is displaceable and with the lever device belonging to the pulling device with a handle can be firmly locked.  

Die mit der Erfindung erzielten Vorteilen bestehen insbesondere darin, 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 by the invention are in particular that, depending on the type of Use, the drawbar can be quickly adjusted in length or completely inserted and the trailer in relatively low spaces z. B. garage, vertically the wall can be parked.
