Description

Fahrrad-Kettenschutz Die Erfindung bezieht sich auf einen Fahrrad-Kettenschutz, bestehend aus einer Deckschiene für den oberen Kettenteil und das Kettenrad. Die Erfindung besteht darin, daß der vordere, das Kettenrad und das Tretlager überdeckende Teil der Deckschiene als Werkzeugkasten ausgebildet und nach vorn aufklappbar ist. Damit ist für den hinteren Teil der Deckschiene eine Verbiegung oder Vereckung fast unmöglich, womit auch das lästige Anschleifen der Ketten gegen die Deckschiene vermieden wird. Mit der Umklappbarkeit des vorderen Teiles wird die Freilegung des ganzen Tretkurbellagergehäuses erzielt, während im abgedeckten Zustand der Inhalt des Werkzeugkastens gegen Verlust oder Entwendung geschützt ist. Soweit ein aufklappbarer Kettenschutz bekangt ist, bezieht sich diese Aufklappbarkeit auf den ganzen Körper und damit auch auf den den eigentlichen Kettenstrang schützenden Teil. In diesem Falle tritt aber besonders leicht ein Verbiegen oder Verecken des Kettenschutzes ein, wodurch das Scheuern der Kette verursacht wird, das der Grund für die Ablehnung solcher Kettenschutzvorrichtungen ist.Bicycle chain guard The invention relates to a bicycle chain guard, consisting of a cover rail for the upper part of the chain and the sprocket. the Invention is that the front, the sprocket and the bottom bracket overlapping Part of the cover rail is designed as a tool box and can be opened forward. This almost bends or warps the rear part of the cover rail impossible, which also avoids the annoying grinding of the chains against the cover rail will. When the front part can be folded down, the whole is exposed Pedal crank bearing housing achieved, while in the covered state the contents of the tool box is protected against loss or theft. So much for a hinged chain guard is known, this opening refers to the whole body and with it also on the part protecting the actual chain strand. In this case occurs but it is particularly easy for the chain guard to bend or warp, as a result of which the chain chafing is caused, which is the reason for the rejection of such Chain guards is.

Die Zeichnung läßt den neuen Gedanken in Abb. i und 2 in räumlicher Darstellung erkennen.The drawing leaves the new idea in Fig. 1 and 2 in spatial terms Recognize representation.

An dem Fahrradrahmen, dessen untere, vom Steuerkopf zum Tretkurbellager führende Strebe doppelt ausgebildet ist, um so gleichzeitig bis zum Lager des Hinterrades durchzulaufen, ist eine feste Deckschiene für den oberen Kettenstrang angebracht (vgl. Abb. i). Der vordere, das Kettenrad und das Tretlager überdeckende Teil dieser Schiene ist nach vorn aufklappbar (vgl. Abb. 2) und gleichzeitig als Werkzeugkasten ausgestaltet, so daß mit seinem Aufklappen eine Freilegung des ganzen Tretkurbellagergehäuses erzielt wird und mit seinem Überklappen der dann untenliegende Deckel gesichert ist.On the bicycle frame, the lower one, from the steering head to the crank bearing leading strut is designed twice, so at the same time up to the bearing of the rear wheel To go through, a fixed cover rail is attached for the upper chain strand (see Fig. i). The front, the sprocket and the bottom bracket covering part of this The rail can be opened to the front (see Fig. 2) and doubles as a tool box designed so that with its unfolding an exposure of the entire pedal crank bearing housing is achieved and secured with its folding over the then underlying cover is.
