Description

Die Erfindung -betrifft einen federnden Rahmen für Fahr- und Motorräder, bei dem die obere waagerechte Rahmenstrebe durch ein Gelenk geteilt und die vom Steuerkopf zum Tretlager verlaufen-de schräge Rahmenstrebe durch eine Federung gegen die hintere Rahmenhälfte abgestützt ist.The invention relates to a resilient frame for bicycles and motorcycles, in which the upper horizontal frame strut is divided by a joint and that of the Steering head to the bottom bracket running diagonal frame strut by a suspension against the rear frame half is supported.

Das Neue wird darin gesehen, daß die Feder in einer am hinteren Rahmenteil in zier Verlängerung der schrägen Rahmenstrebe angeordneten Hülse gelagert ist. Das Neue besteht ferner darin, daß die schräge Rahmenstrebe mittels eines in der Büchse geführten Widerlagers auf die Feder einwirkt. -In der Zeichnung ist eine beispielsweise Ausführungsform veranschaulicht.The novelty is seen in the fact that the spring is in one on the rear frame part is mounted in a decorative extension of the inclined frame strut arranged sleeve. The novelty is also that the inclined frame strut by means of a in the Bushing guided abutment acts on the spring. -In the drawing there is one example embodiment illustrated.

Fig. i zeigt einen Fahrradrahmen, Fig. 2 eine Draufsicht auf die Gelenkstelle des Rahmens, Fig.3 einen Teil der neuen Vorrichtung vergrößert im Vertikalschnitt.FIG. 1 shows a bicycle frame, FIG. 2 shows a plan view of the hinge point of the frame, Fig.3 a part of the new device enlarged in vertical section.

Der Rahmen besteht aus den bekannten Rohrstreben i, 2, 3, 4, 5 und 6, wobei noch eine Rohrstrebe 7 hinzukommen kann. Die Rohrstreben z und 3 werden erfindungsgemäß nicht starr aneinander befestigt, sondern gelenkig durch ein Scharnier 8, 9, und zwar so, daß der ganze vordere Rahmenbau gelenkig nachgeben kann.The frame consists of the known tubular struts i, 2, 3, 4, 5 and 6, whereby a tubular strut 7 can be added. The tubular struts z and 3 are not rigidly attached to each other according to the invention, but articulated by a hinge 8, 9, in such a way that the entire front frame structure can articulately yield.

Die Rahmenstrebe 2 ist am unteren Ende gleichfalls nicht mehr starr mit der Strebe i und dem Achsenlager io verbunden. Diese Rohrstrebe 2 hat am unteren Ehde eine kolbenartige Verlängerung i i. Diese führt in eine Büchse 12, und hat in dieser Führung. Die Büchse i2 ruht befestigt auf einem Tragstutzen 13 des Achsenlagers io und mit ihrem anderen Ende auf dem Rohrstutzen 15 der unterbrochenen Strebe 2. Um die kolbenartige Strebenverlängerung i i ist eine Feder 14 vorgesehen und wird hier zwischen einer Mutter i6 und dem Rohrende der Verstrebung 2 auf bekannte Art befestigt und gehalten.The frame strut 2 is also no longer rigidly connected to the strut i and the axle bearing io at the lower end. This tubular strut 2 has a piston-like extension i i on the lower Ehde. This leads into a sleeve 1 2, and has in this guide. The sleeve i2 rests fastened on a support piece 13 of the axle bearing io and with its other end on the pipe socket 15 of the interrupted strut 2. A spring 14 is provided around the piston-like strut extension ii and is here between a nut i6 and the pipe end of the strut 2 known type attached and held.

Die Wirkungsweise ist wie folgt: Bei einem Stoß von der Fahrbahn bewegt sich der vordere Rahmen 2, 3 und 4 nach oben, so daß die Feder 14 am rechten Ende (Fig. 3) der Hülse 12 befestigt und durch die Mutter 16 von links nach rechts auf Druck beansprucht wird.The mode of operation is as follows: Moved off the road in the event of a shock the front frame 2, 3 and 4 upwards so that the spring 14 is at the right end (Fig. 3) attached to the sleeve 12 and through the nut 16 from left to right Pressure is stressed.
