Description

Die Erfindung betrifft einen neuartigen Rahmen für Fahrräder. Das Hauptmerkmal der Erfindung ist darin zu sehen, daß der sonst übliche hintere Dreieck-Rolirgabelverband zur Aufnahme des Hinterrades vollkommen wegfällt und statt dessen zwei parallel laufende Profilträger, vorzugsweise Ovalrohre, welche am Hauptrahmenrohr in der Nähe des Tretlagers befestigt sind und wovon ein Profilträger gleichzeitig als Kettenschutz dient, allein das Hinterrad des Fahrrades aufnehmen. Ein weiteres Merkmal der Erfindung ist die Anordnung von zwei dünnNvandigen Hilfsrohren, welche einerseits am Steuerkopf, andererseits am hinteren Ende der zwei Profilträger leicht lösbar befestigt sind, wodurch erreicht wird, daß je nach Wunsch das Fahrrad als ausgesprochenes Herren- oder aber als Damen-Fahrrad gefahren werden kann, und zwar als Herren-Fahrrad, wenn die zwei Hilfsrohre am Fahrradrahmen sitzen, und als Damen-Fahrrad, wenn die zwei Hilfsrohre abmontiert sind.The invention relates to a novel frame for bicycles. That The main feature of the invention is to be seen in the fact that the otherwise common rear triangle Rolirgabelverband to accommodate the rear wheel is completely omitted and instead two parallel running profile beams, preferably oval tubes, which on the main frame tube in the Are attached near the bottom bracket and one of which is a profile carrier as a chain guard serves, only take up the rear wheel of the bike. Another feature of the invention is the arrangement of two thin-walled auxiliary pipes, which on the one hand at the control head, on the other hand, at the rear end of the two profile beams are easily detachable, whereby it is achieved that, depending on the wishes, the bicycle as a distinct men's or can be ridden as a women's bike, and as a men's bike, if the two auxiliary tubes sit on the bike frame, and as a ladies bike, if the two Auxiliary pipes are dismantled.

Aus (lern in der Zeichnung dargestellten Ausführungsbeispiel geht hervor, daß der neue Fahrradrahmen nicht nur ein sehr gefälliges Aussehen erhält, sondern auch besondere technische Vorzüge aufweist und sehr einfach ist, so daß derselbe in Serien wirtschaftlich zu niedrigsten Preisen Hergestellt werden kann.From (learn the embodiment shown in the drawing shows that the new bicycle frame not only has a very pleasing appearance, but also has special technical advantages and is very simple, so that the same can be manufactured economically in series at the lowest prices.

Fig. i der Zeichnung zeigt eine Seitenansicht des Fahrradrahmens mit montierten Hilfsrohren als 1 lerreti-Fahrrad ; Fig.2 zeigt den Fahrradrahmen in der Draufsicht ohne Hilfsrohre; Fig. 3 ist ein Schnitt nach Linie A-B der Fig. i. 111 I# ig. i bis 3 ist i der aus einem einzigen Rohr gebogene Hauptrahmen, welcher vorn mit dem sog. Steuerkopf 2 des Fahrrades torsionssteif verbunden ist, an seiner untersten Stelle das Tretlager 3 aufnimmt und hinten oben zur Aufnahme der Sattelstütze mit Sattel (nicht gezeichnet) dient. Ani 1lauptrahmen i in der Nähe des Tretlagers 3 sind an zwei Schraubenaugen 4 und 5, die zwei parallel nach hinten laufenden Profilträger 6 und 7 (< )valrolire) befestigt, welche hinten in Laschen 8 das Hinterrad 9 des Fahrrades aufnehmen. Der gleichzeitig als Schutz für die Fahrradkette dienende Profilträger 6 zeigt vorteilhaft unten eine durchgehende Öffnung i i zur leichten Montage der Fahrradkette. In Tretlagernähe werden beide Profilträger 6 und 7 durch ein geriffeltes Trittblech io abgedeckt. Zur Befestigung der schnell auswechselbaren parallel laufenden zwei Hilfsrohre 12 befindet sich am Steuerkopf 2 ein Schraubenauge 13 und an beiden Profilträgern 6 und 7 je ein Schraubenauge 14.Fig. I of the drawing shows a side view of the bicycle frame with mounted auxiliary tubes as a lerreti bicycle; 2 shows the bicycle frame in plan view without auxiliary tubes; FIG. 3 is a section along line AB of FIG. 111 I # ig. i to 3 i is the main frame bent from a single tube, which is torsionally rigidly connected at the front to the so-called control head 2 of the bicycle, accommodates the bottom bracket 3 at its lowest point and at the top at the rear to accommodate the seat post with saddle (not shown). Ani 1laupframe i near the bottom bracket 3 are attached to two screw eyes 4 and 5, the two parallel profile supports 6 and 7 (<) valrolire) running backwards, which hold the rear wheel 9 of the bicycle in tabs 8 at the back. The profile carrier 6, which also serves as protection for the bicycle chain, advantageously shows a continuous opening ii at the bottom for easy assembly of the bicycle chain. In the vicinity of the bottom bracket, both profile supports 6 and 7 are covered by a corrugated tread plate. A screw eye 13 is located on the control head 2 and a screw eye 14 is located on each of the two profile supports 6 and 7 for fastening the two auxiliary pipes 12, which can be quickly exchanged, run in parallel.
