Abstract

The tool fits a bicycle chain (3) in place, guiding it into engagement with the sprocket teeth (7), after which it is removable. It comprises an elastic tongs (3), with a fork (4) in one free end and a mating protrusion on the other. The clear width between the fork prongs can match the dimensions of the teeth, while the protrusion can match the clear width between adjacent chain rollers (6), and fit in the fork in the shut position. USE/ADVANTAGE - Easy fitting of chain on bicycle.

Description

Die Montage von Zweiradketten bereitet oft Schwierigkeiten, insbesondere wenn das Zweirad einen Kettenschutz aufweist.The assembly of two-wheel chains is often difficult, especially if the two-wheeler has a chain guard.

Aufgabe dieser Erfindung ist es deshalb, ein Montagewerkzeug für Zweiradketten anzugeben, das die Kettenmontage erleichtert.The object of this invention is therefore an assembly tool to be specified for two-wheel chains, which makes chain assembly easier.

Diese Aufgabe wird durch die im Kennzeichen der Patentansprüche der vorliegenden Anmeldung beschriebenen Merkmale erfüllt.This object is achieved in the characterizing part of the claims features described in the present application.

Nachstehend wird die Erfindung unter Bezug auf zwei Zeichnungen erläutert. Es zeigtThe invention will now be described with reference to two drawings explained. It shows

Fig. 1 das erfindungsgemäße Montagewerkzeug in einer Schräg­ bilddarstellung und Fig. 1, the assembly tool according to the invention in an oblique image and

Fig. 2 eine Vorderansicht der freien Enden des Montagewerk­ zeuges mit einem Ausschnitt der Zweiradkette. Fig. 2 is a front view of the free ends of the assembly tool with a section of the two-wheel chain.

Bei der Schrägbilddarstellung in Fig. 1 ist die Form des er­ findungsgemäßen Montagewerkzeuges gezeigt. Das Werkzeug hat die Form einer spangenartigen Zange 3, wobei die freien Enden unterschiedlich gestaltet sind. Das obere Ende weist einen nach unten gebogenen Zapfen 1 auf, während das untere Ende gabelförmig gestaltet ist. Die lichte Weite der Aussparung 2 bei der Gabel 4 ist so gewählt, daß einerseits bei zu­ sammengedrückter Zange 3 der Zapfen 1 in Eingriff gebracht werden kann, anderseits die Gabel 4 auch auf einen Zahn 7 des Zahnkranzes aufgesteckt werden kann. Die Zange 3 ist aus elastischem Material, vorzugsweise dünnem Edelstahl, ge­ fertigt.In the oblique image representation in Fig. 1, the shape of he inventive mounting tool is shown. The tool has the shape of a clip-like pliers 3 , the free ends being designed differently. The upper end has a downwardly bent pin 1 , while the lower end is fork-shaped. The clear width of the recess 2 in the fork 4 is selected so that, on the one hand, the pliers 1 can be engaged when the pliers 3 are compressed, and on the other hand the fork 4 can also be plugged onto a tooth 7 of the ring gear. The pliers 3 is made of elastic material, preferably thin stainless steel.

In Fig. 2 wird der Gebrauch des Montagewerkzeuges verdeut­ licht. Der Zapfen 1 des oberen freien Endes greift dabei zwischen zwei benachbarten Rollen 6 eines Gliedes der Zwei­ radkette 5 ein, während die Gabel 4 die beiden Rollen 6 unterfaßt.In Fig. 2 the use of the assembly tool is clarified light. The pin 1 of the upper free end engages between two adjacent rollers 6 of a link of the two wheel chain 5 , while the fork 4 frames the two rollers 6 .

Das erfindungsgemäße Montagewerkzeug wird wie folgt einge­ setzt: The assembly tool according to the invention is inserted as follows puts:  

Man hakt den Zapfen 1 in ein Kettenglied und drückt das Montagewerkzeug zusammen. Anschließend wird die Kette bis zum Zahnkranz gezogen und dort aufgelegt. Der Zahnkranz wird nun gedreht, wobei die Gabel 4 der Zange 3 zwischen den Zähnen 7 sich befindet. Mit zunehmender Zugspannung der Zweiradkette 5 wird der Zapfen 1 nach oben gedrückt, da sich der Zahn 7 nunmehr in den Zwischenraum der Rollen 6 preßt. Nun läßt man den Zapfen 1 ganz aushaken, indem man die Zange 3 öffnet, und zieht die Zange 3 aus dem Zahnkranz.One hooks the pin 1 into a chain link and presses the assembly tool together. The chain is then pulled up to the sprocket and placed there. The ring gear is now rotated, the fork 4 of the pliers 3 being located between the teeth 7 . With increasing tension of the two-wheel chain 5 , the pin 1 is pressed upwards, since the tooth 7 now presses into the space between the rollers 6 . Now you can unhook the pin 1 by opening the pliers 3 , and pull the pliers 3 out of the ring gear.
