Description
Kettenspannvorrichtung für Fahrräder. Es sind bereits Kettenspannvorrichtungen für Fahrräder bekannt, bei denen die Hinterradachse in der Bohrung einer Platte ruht, deren Zähne in Lücken von an der Außenseite der Hinterradgabel angeordneten Zähnen eingreifen. Soll die Fahrradkette in die richtige Spannung gebracht werden, so wird die gezahnte Platte um eine oder mehrere . volle Zahnteilungen nach vorn oder hinten gerückt. Es kann nun der Fall eintreten, da,ß beispielsweise beim Spannen der gedehnten Kette durch das Vorrücken der Platte um eine volle Zahnteilung die Spannung der Kette zu groß wird.Chain tensioning device for bicycles. There are already chain tensioners known for bicycles in which the rear wheel axle in the bore of a plate rests whose teeth are arranged in gaps on the outside of the rear fork Teeth engage. Should the bicycle chain be brought into the correct tension, so the toothed plate becomes one or more. full tooth pitches to the front or moved back. The case may now arise where, ß, for example at the Tension the stretched chain by advancing the plate by one full pitch the tension in the chain becomes too great.
Dieser den bekannten Kettenspannvorrichtungen anhaftende Nachteil wird erfindungsgemäß dadurch beseitigt, daß die Mitte der Bohrung der -gezahnten Platte gegenüber der Zahnteilung so versetzt angeordnet ist, daß die Hinterradachse beim Drehen der Platte um i8o° nur um eine halbe Zahnteilung verschoben wird.This disadvantage inherent in the known chain tensioning devices is eliminated according to the invention that the center of the bore -toothed Plate is offset from the tooth pitch so that the rear wheel axle when the plate is rotated by 180 ° it is only shifted by half a tooth pitch.
In der Zeichnung ist die Erfindung in einer Ausführungsform dargestellt, und zwar zeigt Abb. i ein Hinterradgabelende mit Platte. In Abb. z ist die Platte um eine volle Zahnteilung gegenüber Abb. i nach vorn verschoben. In Abb.3 ist die Platte um i8o° gedreht und gegenüber Abb. i um eine halbe Zahnteilung nach vorn verschoben.In the drawing, the invention is shown in one embodiment, namely Fig. i shows a rear fork end with a plate. In Fig.z is the plate Shifted forward by one full tooth pitch compared to Fig. i. In Fig.3 is the Plate rotated 180 ° and forward half a tooth pitch compared to Fig postponed.
Abb. q. zeigt das Hinterradgabelende ohne Platte. Wie aus diesen Abbildungen ersichtlich ist, ist die Lochmitte der Platte um ein Viertel einer Zahnteilung versetzt angeordnet. Damit beim Nachspannen der Kette die richtige Seite der Platte schnell gefunden wird, sind die Schmalseiten der Platten konvex und konkav ausgeführt. Es kann natürlich auch eine andere Kennzeichnung an der Platte angebracht werden.Fig.q. shows the rear fork end without plate. As from these pictures As can be seen, the center of the hole in the plate is offset by a quarter of a tooth pitch arranged. This means that when the chain is re-tensioned, the correct side of the plate can be found quickly is found, the narrow sides of the plates are convex and concave. It Of course, another marking can also be attached to the plate.
