     Ais Untcrtagsscheiben   für   Nippotköpfe   wurden bisher, um ein Ausreissen der Köpfe aus der Felge zu verhüten,   Nippetunterlagsscheilien verwendet, wie   die beiliegende Fig. 1 veranschaulicht. 



   Die Unterlagsscheibe a betindet sich zwischen dem Nippelkopf b und der Fahrradfelge c, (Fig. 2). Es wurde hierbei als ein grosser Übelstand empfunden, dass diese Unter-   lagsscheibcH1   nicht vollkommen fest zwischen Felge und Nippelkopf lagen, wodurch es sehr leicht vorkommen konnte, dass sich die Unterlagsscheiben aus der ihnen angewiesenen Lage bei der Weiterverarbeitung des Rades verschoben oder drehten und dadurch in der Felge Unebenheiten verursachten und die Stabilität des Hades beeinflussten.

   Diesem   Uebelstande   abzuhelfen wurde die den Gegenstand der vorliegenden Erfindung bildende Einrichtung getroffen, welche darin besteht, dass die Unterlagsscheiben in dem Loch der Felge zur   Hindurchführung   des Nippelbolzens befestigt werden, derart, dass der Lochrand der   Unterlagsscheibe'n   aufgebogen und in die Bohrung der Felge hineingepresst wird, so dass der aufgebogene Rand auf der Aussenseite der Felge annähernd gleich liegt mit der Felgenoberfläche oder etwas hervorsteht. Die Unterlagsscheibe wird durch das Aufbiegen des Lochrandes bedeutend stärker. Durch diese Anordnung wird der oben erwähnte Übel-

 einen viel grösseren Widerstand gegen das Ausreissen der Nippelköpfe. 



   Fig. 3 veranschaulicht die neue Einrichtung. 



     Die Unterlagsscheibc a   hat einen inneren aufgebogenen Lochrand a1, welcher in die Bohrung der   Felge r durch   eine geeignete   Stanzvorrichtung hineingeprest   wird, so dass Unterlagsscheibe und Felge fest miteinander verbunden sind.

 EMI1.1
 



     As washer disks for Nippot heads, in order to prevent the heads from tearing out of the rim, Nippet washer washers have been used, as the enclosed FIG. 1 illustrates.



   The washer a is located between the nipple head b and the bicycle rim c, (Fig. 2). It was felt to be a major drawback that these washers were not completely fixed between the rim and the nipple head, so that it could very easily happen that the washers shifted or turned out of their assigned position during further processing of the wheel and thus in caused bumps in the rim and affected the stability of Hades.

   This inconvenience was remedied by the device forming the subject of the present invention, which consists in fastening the washers in the hole in the rim for the passage of the nipple bolt in such a way that the edge of the hole in the washers is bent up and pressed into the bore of the rim so that the upturned edge on the outside of the rim is approximately the same as the rim surface or protrudes slightly. The washer becomes significantly stronger by bending the edge of the hole. By this arrangement the above-mentioned evil
 EMI1.2
 a much greater resistance to pulling out the nipple heads.



   Figure 3 illustrates the new facility.



     The washer a has an inner, bent up hole edge a1, which is pressed into the bore of the rim r by a suitable punching device, so that the washer and rim are firmly connected to one another.
