Description

Rahmen für Fahrräder, Motorräder u. dgl. Die Erfindung betrifft einen Rahmen für Fahrräder, Motorräder u. dgl., bei welchem die Rohre und die Muffen gegenseitig verschraubt, anstatt wie bisher gelötet oder geschweißt werden.Frame for bicycles, motorcycles and the like Frame for bicycles, motorcycles and the like, in which the pipes and the sleeves are mutually screwed instead of soldered or welded as before.

Bei Rahmen, deren sämtliche Rohre mit den Muffen verschraubt werden, bietet das Einschrauben des den Schluß bildenden Rahmenrohres, nachdem alle anderen Teile fest verschraubt sind, Schwierigkeiten, da das Einschrauben des Schlußrohres im allgemeinen nur möglich ist, wenn eine starke Verbiegung der Rahmenrohre vorgenommen wird, die jedoch äußerst schädlich ist, leicht zum Bruch führen kann und deshalb vermieden werden muß.For frames in which all pipes are screwed to the sleeves, offers the screwing in of the final frame tube after all the others Parts are screwed tightly, difficulties as the screwing in of the end tube is generally only possible if the frame tubes are bent sharply which, however, is extremely harmful, can easily break and therefore must be avoided.

Die Erfindung beseitigt diese Nachteile, und zwar dadurch, daß die Schlußmuffe aus zwei Hälften besteht und das Sitzrohr, welches als Schlußrohr dient, an seinem oberen Ende unter-und oberhalb der Schlußmuffe mit Anschlägen versehen wird. Hierdurch kann das Schlußrohr nach Entfernen der äußeren Hälfte der Sattelmuffe leicht mit seinem unteren Ende in die zugehörige Muffe des Tretlagergehäuses eingeschraubt werden und wird dann durch Zusammenschrauben der Schlußmuffenhälften am oberen Rohrende in seiner Lage festgehalten und an dem Losdrehen verhindert.The invention eliminates these disadvantages, in that the The end sleeve consists of two halves and the seat tube, which serves as the end tube, provided with stops at its upper end below and above the closing sleeve will. This allows the end pipe after removing the outer half of the saddle sleeve slightly screwed with its lower end into the corresponding sleeve of the bottom bracket housing and is then screwed together the socket halves at the upper end of the pipe held in place and prevented from loosening.

Auf der Zeichnung ist die Erfindung dargegestellt, und zwar zeigt: Abb.= denRahmen fertig zusammengeschraubt im Schnitt, Abb. 2 die Schlußmuffe mit der hinteren abgenommenen Hälfte, Abb. 3 die geschlossene Schlußmuffe in Draufsicht.In the drawing, the invention is shown, namely shows: Fig. = The frame completely screwed together in section, Fig. 2 the closing sleeve with the rear removed half, Fig. 3 the closed closing sleeve in plan view.

An beiden Hälften der Schlußmuffe a sind zu beiden Seiten Ösen b für Schrauben c angebracht, welche dazu dienen, die Muffenhälften am oberen Rohrende zusammenzuhalten.On both halves of the final socket a there are eyelets b for on both sides Screws c attached, which are used to fasten the sleeve halves at the upper end of the pipe to stick together.

Die ober- und unterhalb der Schlußmuffe a an dem oberen Ende des Sitzrohres f angebrachten Anschläge d geben der Schlußmuffe einen festen Sitz und verhüten also das Verschieben derselben und des mit ihr verbundenen oberen Rahmenrohres e.The above and below the final sleeve a at the upper end of the seat tube f attached stops d give the final socket a tight fit and prevent it thus moving the same and the upper frame tube connected to it e.

Die Anschlagringe d und das obere Sitzrohrende werden zweckmäßig mit Gewinde versehen, was den Vorteil hat, daß dann die Schlußmuffe a und das obere Rohr e in der Höhenlage genau einstellbar sind.The stop rings d and the upper end of the seat tube are useful with Provided thread, which has the advantage that then the final sleeve a and the upper Tube e are precisely adjustable in height.

Durch die vorerwähnte Anordnung lassen sich alle Rohre mit den Muffen fest verbinden, ohne daß irgendwelche schädliche Verbiegungen der Rahmenrohre erforderlich werden.Due to the aforementioned arrangement, all pipes with the sleeves Connect firmly without any harmful bending of the frame tubes required will.
