Description
Es sind bei Fahrrädern Mehrfachkettenschaltungen bekannt, bei denen das Antriebskurbelrad in horizontaler Richtung mehrere Zahnräder aufweist. Dabei ist antriebsseitig meist ein baudenzuggesteuerter Bügel vorgesehen, der die Kette umschaltet.Multiple derailleur gears are known on bicycles, where the drive crank wheel has several gears in the horizontal direction. In this case, a cable-controlled bracket is usually provided on the drive side, which switches the chain.
Der Nachteil bei diesem System besteht darin, daß die Kette schutzlos -insbesondere der Hose- des Fahrer ausgesetzt ist.The disadvantage of this system is that the chain is exposed to no protection - especially the rider's trousers.
Der Erfindung liegt die Aufgabe zu Grunde einen besonders einfachen auch nachträglich montierbaren Schutz zu schaffen.The invention is based on the object of creating a particularly simple protection that can also be retrofitted.
Diese Aufgabe wird bei einer Anordnung gemäß Oberbegriff gemäß Kennzeichen des Anspruchs 1 gelöst.This object is achieved in an arrangement according to the preamble according to the characterizing part of claim 1.
Weitere vorteilhafte Ausgestaltung des Erfindungsgegenstandes sind in den Unteransprüchen gekennzeichnet.Further advantageous embodiments of the subject matter of the invention are characterized in the subclaims.
Nachstehend wird die Erfindung an Hand der Figuren 1 und 2 näher erläutert:
Figur 1 zeigt eine Seitenansicht einer Mehrfachschaltung in chematischer Darstellung.
Figur 2 zeigt eine in Figur 1 mit X gekennzeichnete Ansicht des vorderer Schaltungsteils.The invention is explained in more detail below with reference to Figures 1 and 2:
Figure 1 shows a side view of a multiple circuit in a schematic representation.
Figure 2 shows a view of the front circuit part marked with X in Figure 1.
Mit dieser Erfindung kann Jederman ein Fahrrad mit Mehfachkettenschaltung, sei es ein Rennrad, Mountainbike, Trekkingrad oder Tourenrad in normaler Straßenkleidung führen, ohne seine Kleidung -insbesondere die Hose- an der meist öligen Kette zu verschmutzen.With this invention, anyone can ride a bicycle with multiple derailleur gears, be it a racing bike, mountain bike, trekking bike or touring bike, in normal street clothes, without getting their clothes - especially their trousers - dirty on the usually oily chain.
Der Kettenschutz kann herstellerseitig im Werk montiert, oder auch mit einfachen Hilfsmitteln nachgerüstet werden.The chain guard can be fitted by the manufacturer in the factory or retrofitted using simple tools.
Durch die Verklebung des Kettenschutzes mit dem Schaltbügel wird sichergestellt, daß der Kettenschutz beim Schaltvorgang in horizontaler Richtung mitgeführt wird und immer die Kette bedeckt. Es ist hierbei unerheblich ob die Kette auf dem größten oder kleinsten Antriebszahnrad aufgelegt ist, der Schutz der Kleidung ist immer gegeben.By gluing the chain guard to the shift bar, it is ensured that the chain guard is moved horizontally during the shifting process and always covers the chain. It does not matter whether the chain is placed on the largest or smallest drive gear, the clothing is always protected.
