Description

Die Erfindung bezieht sieh auf einen zerlegbaren Fahrradrahmen. Solche Rahmen sind vorteilhaft zum Transport in Verkehrsmitteln, auf Treppen und zur Aufbewahrung in engen Räumen.The invention relates to a collapsible bicycle frame. Such Frames are advantageous for transport in vehicles, on stairs and for storage in tight spaces.

Es sind bereits zerlegbare Fahrradrahmen bekannt, bei denen sich das Tretlager an dem einen Teil und das Hinterrad mit seinen Gabeln an dem anderen Teil des zerlegbaren Fahrrades befinden. Diese bekannten Ausführungen haben den Nachteil, daß die Kette zum Zerlegen das Fahrrades abgenommen und beim Zusammensetzen wieder aufgelegt werden muß. Dadurch entstehen Zeitverluste und unter Umständen ein Beschmutzen -des Benutzers.There are already demountable bicycle frames known in which the Bottom bracket on one part and the rear wheel with its forks on the other part of the collapsible bike. These known designs have the disadvantage that the chain was removed to disassemble the bike and reassembled must be placed. This results in loss of time and, under certain circumstances, soiling -of the user.

Die Erfindung bezweckt demgegenüber die Gestaltung eines zerlegbarenFahrradrahmens; bei dem die Kette und ihr Zubehör, wie Kettenschutz, bei der Zerlegung nicht abgenommen werden und bei der gleichzeitig eine Federung des Hinterrades möglich ist. Dies wird dadurch erreicht, daß das Tretlager mit der hinteren Radlagerung fest verbunden bleibt und die Verbindung zwischen der unteren-Radgabel und dem vorderen Teil des Rahmens durch eine Verschraubung erfolgt. Die obere Hinterradgabel stützt sich dabei über eine zerlegbare Teleskopfederung gegen den vorderen Rahmenteil ab.The invention, on the other hand, aims at the design of a collapsible bicycle frame; in which the chain and its accessories, such as the chain guard, are not removed during disassembly and with which a suspension of the rear wheel is possible at the same time. this is achieved in that the bottom bracket is firmly connected to the rear wheel bearing remains and the connection between the lower wheel fork and the front part of the Frame is done by a screw connection. The upper rear fork is supported here via a telescopic suspension that can be dismantled against the front frame part.

In der Zeichnung ist die Erfindung in einem Ausführungsbeispiel dargestellt. Es zeigt -Abb. z eine Seitenansicht des zusammengebauten Fahrrades, Abb. 2 den vorderen Teil des zerlegbaren Fahrradrahmens, Abb. 3 den hinteren Teil des zerlegbaren Fahrradrahmens, Abb. q. einen Schnitt durch die Schraubverbindung.In the drawing, the invention is shown in one embodiment. It shows - Fig. z is a side view of the assembled bicycle, Fig. 2 the front Part of the collapsible bicycle frame, Fig. 3 the rear part of the collapsible bicycle frame, Fig.q. a section through the screw connection.

Der vordere Teil des zerlegbaren Fahrradrahmens besteht aus der-Vorderradgabel i mit dem Vorderrad und der Lenkeinrichtung, dem üblichen trapezförmigen Rahmengestell 2, einem Teil der oberen Hinterradgabel q. mit eingehängter Feder 5 und der Schraubeinrichtung 6, die sich an der Stelle des üblichen Tretlagers befindet. Der hintere Teil des zerlegbaren Rahmens besteht aus dem unteren Teil 7 der oberen Hinterradgabel, der unteren Hinterradgabel 8, dem mit ihr verbundenen Vorbau 9 zur Aufnahme des Tretlagers io mit vorderem Kettenrad ii und dem entsprechenden Teil der Schraubverbindung. Beim Zusammenbau wird der Teil 7 über den Teil q. geschoben, so daß sich das Hinterrad gegen die Feder 5 auf den vorderen Rahmenteil abstützt. Dann wird der Teil der Schraubverbindung der unteren Gabel 8 mit dem entsprechenden Teil der Schraubeinrichtung 6 des vorderen Rahmenteils durch die Schraube 12 verbunden.The front part of the collapsible bicycle frame consists of the front fork i with the front wheel and the steering device, the usual trapezoidal frame 2, part of the upper rear fork q. with suspended spring 5 and the screw device 6, which is located in the place of the usual bottom bracket. The rear part of the dismountable frame consists of the lower part 7 of the upper rear fork, the lower rear fork 8, the stem 9 connected to it for receiving the bottom bracket io with front sprocket ii and the corresponding part of the screw connection. When assembling the part 7 is over the part q. pushed so that the rear wheel supported against the spring 5 on the front frame part. Then the part of the screw connection the lower fork 8 with the corresponding part of the screw device 6 of the front Frame part connected by the screw 12.
