Description
Rohrverbindung für gelötete Fahrradrahmen. Die Erfindung betrifft eine Rohrverbindung für gelötete Fahrradrahmen, bei welcher an jeder Verbindungsstelle das eine der zu verbindenden Rohre über eine in eine Öffnung des anderen Rohres eingeführte und fixierte Tülle fest aufgeschoben wird. Das Wesen der Erfindung besteht darin, daß die Tüllen einen umgebördelten Rand besitzen, auf den die aufgeschobenen Rohre aufstoßen und der sich gegen die innere Rohrwand des anderen Rohres legt, während in das letztere in Höhe der Tülle ein Futterrohr mit Spielraum eingeschoben ist, welches über den Tüllenrand aufgewalzt ist.Tube connection for soldered bicycle frames. The invention relates to a pipe connection for soldered bicycle frames, in which at each connection point one of the pipes to be connected via one into an opening of the other pipe inserted and fixed grommet is firmly pushed on. The essence of the invention consists in that the spouts have a beaded edge on which the pushed Push open pipes and which lies against the inner pipe wall of the other pipe, while in the latter at the level of the spout a pipe sleeve with clearance is inserted is, which is rolled over the nozzle edge.
Die Zeichnung zeigt in Abb. z bis 3 Schnitte von zu verlötenden Rohrverbindungen, die gemäß der Erfindung ausgebildet sind.The drawing shows in Fig. Z up to 3 sections of pipe connections to be soldered, which are designed according to the invention.
Abb. q. zeigt die Verbindung mehrerer Rohre, wie sie beim Tretlager erforderlich ist. Das mit dem Rohr a zu verlötende Hauptrohr b besitzt eine Öffnung c, in welche Tüllen e mit umgebördeltem, sich gegen die Wand des Rohres b legenden Rand eingeführt sind. Über diese Tüllen ist das Rohr a fest aufgeschoben, so daß es mit seiner Stirnfläche auf den Tüllenrand aufstößt. Ein in das Rohr b in Höhe der Tüllen c mit Spielraum eingeschobenes und über den Tüllenrand aufgewalztes Futterrohr d fixiert die Tüllen und damit das mit dem Rohr b zu verbindende, über die Tüllen c geschobene Rohr a in der Öffnung c des Rohres b. Hierdurch werden die Rohre in der gewünschten Stellung festgehalten und bilden kleine Zwischenräume, in die sich das die Rohre innig verbindende Lot mit Sicherheit festsetzt, so daß eine einfache und sichere Verlötung erzielt wird.Fig.q. shows the connection of several tubes, as it is necessary for the bottom bracket. The main pipe b to be soldered to the pipe a has an opening c into which grommets e with a flanged edge lying against the wall of the pipe b are inserted. The tube a is pushed firmly over these grommets so that its end face hits the edge of the grommet. Into the tube of the spouts b in height c with clearance Dovetailed and the Tüllenrand rolled-casing d fixes the grommets, and thus the to the pipe b to be connected, via the spouts c pushed pipe a in the opening c of the pipe b. As a result, the pipes are held in the desired position and form small spaces in which the solder which intimately connects the pipes is fixed with certainty, so that simple and secure soldering is achieved.
Bei der Tretlagerrohrverbindung (Abb. q.) werden durch das Futterrohr f gleichzeitig mehrere Tüllen fixiert.At the bottom bracket tube connection (Fig. Q.), Through the casing tube f fixed several grommets at the same time.
