Description

Eiei den bekannten Kettenumschaltvorrichtungen mit Kettenwechsel zwischen mehreren verschieden großen Kettenrädern an der Hinterradnabe von Fahrrädern ist für jede Ausführung der Gabelenden am Fahrradrahmen ein besonderer Träger für die Kettenumschaltvorrichtung notwendig. Bei den Gabelenden werden in erster Linie zwei Ausfiihrungen unterschieden: die nach rückwärts offenen Gabelenden, meist für Tourenräder, und die schräg nach vorn offenen, meist für Sport- und Rennräder. Die Anfertigung verschiedenartiger Träger für diese Einbaufälle verteuern die Kettenschaltvorriclitungen, außerdem besteht die Gefahr der Verwechslung der einzelnen Trägerarten.Eiei the known chain switching devices with chain change between several different sized sprockets on the rear hub of bicycles for each version of the fork ends on the bicycle frame a special carrier for the Chain switching device necessary. At the fork ends there are primarily two There are different versions: the fork ends that are open towards the back, mostly for touring bikes, and the ones that are open at an angle, mostly for sports and racing bikes. The manufacture Different types of carrier for these installation cases make the chain gearshift devices more expensive, there is also the risk of confusing the individual types of carrier.

Diese Nachteile werden durch den Erfindungsgegenstand vermieden. Danach hat ein offener Schlitz des Trägers zum Aufnahmebolzen für die Kettenuinsclialtvorrichtung eine derartige Lage, daß das von der Achse des Aufnahmebolzens auf die Mittellinie des Schlitzes des Trägers gefällte Lot diese Mittellinie innerhalb der Schlitzlänge trifft, und eine derartige Ausbildung, daß er auf beiden Seiten der Hintergabel mit einem nach vorn oder nach rückwärts offenen Gabelendenschlitz zur Deckung gebracht werden kann, und die Befestigung des Aufnahmebolzens an dem Träger ist so ausgeführt, claß der Aufnahmebolzen von beiden Seiten ani Träger angebracht werden kann. Es ist also möglich, den Träger linksseitig oder rechtsseitig, und zwar sowohl bei einem nach vorne offenen als auch bei einem nach 'hinten offenen Gabelendenschlitz am Fahrradraliinen anzubringen. Es wird zweckmäßig das Loch zur Befestigung des Aufnahmebolzens am Träger mit einem durchgehenden Gewinde versehen, in das dieser von beiden Seiten eingeschraubt werden kann.These disadvantages are avoided by the subject matter of the invention. Thereafter has an open slot in the carrier for the locating pin for the chain clip device such a position that that from the axis of the locating pin to the center line Plumb this center line within the slot length of the slit of the carrier meets, and such a training that it is on both sides of the rear fork brought into congruence with a fork end slot open to the front or to the rear can be, and the fastening of the locating bolt on the carrier is carried out in such a way that The locating bolt can be attached to the carrier from both sides. It is therefore possible, the carrier on the left or on the right, both at an open to the front as well as a fork end slot open to the rear to be attached to the bicycle lane. It is appropriate to use the hole to attach the Locating bolt on the carrier provided with a continuous thread into which this can be screwed in from both sides.

In der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes dargestellt.The drawing shows an embodiment of the subject matter of the invention shown.

Abb. i zeigt eine Kettenumschaltvorrichtung mit dein ueuartigen Träger an einem Fahrradrahmen mit nach rückwärts offenen Gabelenden, wie diese bei Tourenrädern gebräuchlich sind; Abb. 2 zeigt denselben Träger an einem Fahrradrahmen mit schräg nach vorn gerichteten Ausfallenden, wie diese bei Sport- und Rennrädern gebräuchlich sind.Fig. I shows a chain switching device with your original carrier on a bicycle frame with fork ends open to the rear, like these on touring bicycles are common; Fig. 2 shows the same carrier on a bicycle frame with angled forward-facing dropouts, such as those commonly used on sports and racing bikes are.

_11>l>. 3 zeigt die Kettenschaltvorrichtung gemäß Abb. i in einem Teilschnitt senkrecht zu den Ansichten gemäß :11>1>. i und 2._11> l>. 3 shows the derailleur device according to FIG. I in one Partial section perpendicular to the views according to: 11> 1>. i and 2.

Durch die Abbildungen wird die @'erwendungsmöglichkeit des gleichen Trägers i bei zwei ver- schiedenen Arten von Gabelenden verdeutlicht. Der Träger i ist mit einem offenen Schlitz 2 versehen, der mit dem Schlitz in dem Gabelende 3 des Fahr- radrahmens .4 zur Deckung gebracht werden kann. Dabei wird die Lage des Aufnahmebolzens 5'fiir die Kettenschaltvorrichtung gegenüber den Ketten- rädern nicht wesentlich geändert, so daß das ein- -,vandfreie Arbeiten des hettenschalträdchens 6 in beiden Fällen gewährleistet ist. lies wird dadurch erreicht, daß das von der :\clise des Aufnahme- holzens auf die '.Mittellinie des Schlitzes des Trä- gers gefällte Lot diese Mittellinie innerhalb der Schlitzlänge trifft. Der Träger i ist durch drei Niete" am Gabelende befestigt. In dem Loch 8 zur Befestigung des Aufnahmebolzens o ist ein durchgehendes Gewinde eingeschnitten. Der Auf- nahmebolzen kann bei Verwendung des Trägers i nach Abb. i von der einen Seite, bei Verwendung des Trägers r nach Abb. 2 von der anderen Seite in den Träger eingeschraubt werden. Für die Kettentimsclialtvorriclitun:; ist durch Anwendung des 1-rfindungsgegenstandes nur ein Träger i nötig, der für alle Arten von Gabelenden geeignet ist, während bis jetzt für die verschiedenen Arten der Gabelenden vcrscliiedenartige Träger notwendig waren. The illustrations show the possibility of using the same carrier i in the case of two different types of fork ends. Of the Carrier i is provided with an open slot 2, the one with the slot in the fork end 3 of the Radrahmens .4 can be brought to the cover. The position of the locating bolt is 5 'for the chain shifting device opposite the chain wheels not significantly changed, so that the one -, wall-free work of the 6 in is guaranteed in both cases. read becomes thereby achieves that the: \ clise of the recording on the center line of the slot of the carrier gers precipitated plumb this center line within the Slot length meets. The carrier i is through three Rivet "attached to the fork end. In the hole 8 for fastening the locating bolt o is a cut through thread. The up Take-up bolts can when using the carrier i according to Fig. i from one side, when using of the carrier r according to Fig. 2 from the other side be screwed into the carrier. For the Kettentimsclialtvorriclitun :; is through Application of the 1-subject matter of the invention only one Carrier i needed for all types of fork ends is suitable while up to now for the different Types of fork ends of different types of beams were necessary.
