Description

Die Erfindung hetrifft eine Vorrichtung zum Höhemeinstellen einer Anhängerzuggabel, die aus einem teleskopartig ausziehbaren Stützrohr besteht, dessen gegeneinander verschiehbare Teile in verschiedenen Stellungen zueinander feststellbar sind. Diese bekannten Ausführungen haben gewisse Nachteile, da sie entweder zu schwierig im Aufbau sind oder nicht von einer Person zu bedienen sind.The invention relates to a device for adjusting a height Trailer drawbar, which consists of a telescopically extendable support tube whose mutually displaceable parts can be determined in different positions to each other are. These known designs have certain disadvantages, being either too difficult are under construction or cannot be operated by one person.

Die Erfindung, die diese Mängel beseitigen soll, besteht darin, daß das Innenrohr der Stützvorrichtung mit parallelen Querrillen versehen ist und auf dem äußeren Rohr in einem Zvlinder ein mit einem Nocken versehener Kolben gleitbar ist, der unter dem Einfluß einer Druckfeder bestrebt ist, mit seinen Nocken. in die Querrillen einzufallen und durch einen Handhebel über einen ßowdenzug aus den. Querrillen aushebbar ist.The invention which is intended to remedy these shortcomings is that the inner tube of the support device is provided with parallel transverse grooves and on A piston provided with a cam is slidable over the outer tube in a cylinder is, which strives under the influence of a compression spring with its cams. in collapse the transverse grooves and by a hand lever over a ßowdenzug out of the. Transverse grooves can be lifted.

In der Zeichnung ist die Erfindung dargestellt. Abb. I zeigt die Gesamtanordnung der Vorrichtung; Abb. 2 zeigt die Vorrichtung selbst im Längsschnitt.The invention is shown in the drawing. Fig. I shows the overall arrangement the device; Fig. 2 shows the device itself in longitudinal section.

Im Rohr I ist ein mit parallelen Zahnungen versehenes Rundeisen 2 geführt, das von den Rasten eines Kolbens 7 an Längsbewegungen gehindert wird. Dieser Kolben, der an der Innenfläche zwei Rasten. hat, wird durch den Schraubdeckels und eine Druckfeder 6 im Zylinder 3 mit Führungsbolzen 8 stets nach Innen gepreßt. Vor dem Ankuppeln des Anhängers wird der Bowdenzug 4 angezogen, wobei der Kolben gehoben wird und das Rundeisen frei beweglich wird. Diese Vorrichtung kann an auflauf- und druckluftgebremste Anhänger angebracht werden.In the pipe I is a round iron 2 provided with parallel serrations out, which is prevented by the notches of a piston 7 from longitudinal movements. This Piston with two notches on the inner surface. has, is through the screw cap and a compression spring 6 in the cylinder 3 with guide pin 8 is always pressed inwards. before When the trailer is hitched up, the Bowden cable 4 is pulled and the piston is lifted and the round bar can move freely. This device can be used on casserole and Air-braked trailers are attached.
