Abstract

The conventional slot (1) of the bicycle fork arm (2) is spring-connected by means of a union plate of metal (3) and the spiral spring (4) with the axle (5) of the front wheel. The spring combination (1-6) can also be formed by other corresp. construction means. The system is sufficiently simple to adopt that it can be fitted to existing bicycles without submitting them to a specialised workshop, and it is installed in the extended slot completely within the fork arm (2). It is effected by means of steel springs or elastic buffer components of rubber or plastics, or by other materials with sprung characteristics. USE - As a sprung support for the front wheel fork of a bicycle.

Description

Es sind Federungsvorrichtungen bekannt, die als Teleskop- oder Spiralfeder-Systeme sowohl innerhalb des vorderen Rahmenrohrs (in dem gleichzeitig das Gabelkopfrohr und der Lenkmechanismus untergebracht sind) als auch im hinteren Rahmenrohr (in dem gleichzeitig das Sattelstützrohr untergebracht ist) eingebaut sind.Suspension devices are known which are used as telescopic or coil spring systems both within the front Frame tube (in which the fork head tube and the steering mechanism are housed) as well as in the rear Frame tube (in which the seat post tube is housed) are installed.

Infolge ihres Material- und Lohnaufwands sind diese Vorrichtungen kostspielig und haben außerdem den Nachteil, daß sie wegen der verschiedenen Dimensionen der Rahmenrohre nicht in jedes Fahrrad eingebaut werden können. Ihre nachträgliche Montage in vorhandene Fahrräder ist ohnehin nur in einer Werkstück möglich.Due to their material and wages, these devices are expensive and also have the disadvantage that because of the different dimensions of the frame tubes cannot be installed in every bicycle. Your retrofitting is in existing bicycles anyway only possible in one workpiece.

Erfindungsgemäß werden diese Nachteile dadurch behoben, daß sie vom Fahrradeigner selbst nachträglich eingebaut werden können und vorallem aber einen geringeren Anschaffungswert haben.According to the invention, these disadvantages are eliminated by that they are installed by the bike owner himself can be and above all a lower purchase value to have.

Nachstehend werden anhand der Zeichnungen zwei Ausführungsbeispiele wie folgt erläutert:Below are two embodiments with reference to the drawings explained as follows:

Fig. 1: Die Achse 5 des Vorderrads ist im Gegensatz zur bisher üblichen Konstruktion nicht direkt in den Schlitzen 1 der Gabelarme 2 gelagert; diese Verbindung erfolgt vielmehr erfindungsgemäß durch die beiderseitigen Verbindungsplatten 3, die an einem oder an beiden Enden mit Spiralfedern 4 versehen sind und den Federungshub 1-6 bewirken und ihn begrenzen. Fig. 1: The axle 5 of the front wheel is, in contrast to the previously common construction, not directly supported in the slots 1 of the fork arms 2 ; Rather, this connection is made according to the invention by the connecting plates 3 on both sides, which are provided at one or both ends with spiral springs 4 and cause the suspension stroke 1-6 and limit it.

Fig. 2 zeigt den Federungsmechanismus in den verlängerten Schlitzen 1 der Gabelarme 2 und ist somit ausschließlich im Gabelarmenbereich untergebracht. Die Vorderradachse 5 befindet sich im unbelasteten Zustand des Vorderrads am unteren Ende 3 der verlängerten Schlitze 1 und wandert bei Belastung stufenlos zur Position 6. Der Federungshub wird durch die Spiralfeder 7 oder mittels elastischer Pufferelemente aus Gummi oder Kunststoff oder durch andere federnde Materialien oder durch Federungs-Kombinationen bewirkt. Fig. 2 shows the suspension mechanism in the elongated slots 1 of the fork arms 2 and is therefore housed exclusively in the fork arm area. The front wheel axle 5 is in the unloaded state of the front wheel at the lower end 3 of the elongated slots 1 and moves continuously to position 6 when loaded. The suspension stroke is effected by the spiral spring 7 or by means of elastic buffer elements made of rubber or plastic or by other resilient materials or by suspension combinations.
