Description

Abziehvorrichtungen für Fahrradtretkurbeln sind in verschiedenen Ausführungen bekannt. Diese bekannten Vorrichtungen erfüllen aber ihre Aufgabe nur sehr unvollkommen, oder sie sind sehr kompliziert. Die Abziehvorrichtung nach der Erfindung ist dagegen sehr einfach im Aufbau und zuverlässig in der Wirkung.Pullers for bicycle cranks are available in different designs known. However, these known devices fulfill their task only very imperfectly, or they are very complicated. The puller according to the invention is against it very simple in construction and reliable in effect.

Wie aus der Zeichnung ersichtlich, ist ein Abziehstück i mittels einer beispielsweisen U-förmigen Klammer 2 und einer Spannschraube 3 an der abzuziehenden Tretkurbel 8 befestigt. Das Abziehstück i weist am Kopf ein Muttergewinde zur Aufnahme einer Druckschraube 4 auf. Durch einen Keil 5 und einen U-förmigen Bügel 6, der über das Ende der abzuziehenden Tretkurbel und die Gabel des Hinterrades gesteckt ist, wird die Tretkurbel gegen Verbiegung und Drehung beim Abziehen gesichert. Bei Nichtgebrauch der Vorrichtung wird das Abziehstück i durch eine Halteschiene 7 an der Klammer 2 festgehalten.As can be seen from the drawing, a puller i is by means of a for example U-shaped bracket 2 and a tensioning screw 3 on the to be withdrawn Crank 8 attached. The pull-off piece i has a female thread on the head for receiving it a pressure screw 4. By a wedge 5 and a U-shaped bracket 6, the put over the end of the crank to be withdrawn and the fork of the rear wheel the crank is secured against bending and turning when it is pulled off. at When the device is not in use, the puller i is attached by a holding rail 7 the bracket 2 held.

Bei Eindrehen der Druckschraube 4 stützt sich diese gegen das Ende der Tretlagerachse 9 ab, wodurch das Abziehen der Tretkurbel erfolgt.When screwing in the pressure screw 4, it is supported against the end the bottom bracket axle 9, whereby the pulling off of the pedal crank takes place.
