Fahrrad-RahmenBicycle frame

Vorliegende Erfindung betrifft einen in Schalenbauweise gefertigter Fahrrad-Rahmen,der aus einem verformbaren Werkstoff hergestellt ist.The present invention relates to a bicycle frame made of a shell construction and made of a deformable material.

Insbesondere betrifft die Erfindung ein,vorzugsweise aus Metallblech gefertigter Fahrrad-Rahmen.Ein Fahrrad-Rahmen als Formblechteil,bestehend aus zwei zusammengefügte Halbschalen ,geeignet für die Großserien-Fertigung.Zürn Beispiel kann im Produktionsfall ein vom Coil abgezogenes Blech durch die Presse gefahren und als Formblechteil ausgeworfen werden.Analog der Karossenfertigung in der Automobil-Industrie . Anschließend können die beiden Formblechteile von einem Schweißautomaten zu einem Fertigrahmen miteinander verbunden werden.In particular, the invention relates to a bicycle frame, preferably made of sheet metal. A bicycle frame as a formed sheet metal part, consisting of two joined half shells, suitable for large-scale production. For example, in production, a sheet metal pulled from the coil can be run through the press and ejected as a formed sheet metal part. Analogous to body production in the automobile industry. The two formed sheet metal parts can then be joined together by a welding machine to form a finished frame.

Bekannte Fahrrad-Rahmen werden im allgemeinen aus Metall-Rohren unterschiedlicher Abmessungen und verschiedenster Formen,die wiederum durch Muffen miteinander verbunden sind,hergestellt.Diese Herstellung macht in der Regel Lot-,und autogene Schweißarbeiten sowie Gewindeschneiden manuell erforderlich.was die Herstellkosten erheblich beeinflußt.Well-known bicycle frames are generally made from metal tubes of different dimensions and shapes, which are in turn connected to one another by sleeves. This production usually requires manual soldering and autogenous welding as well as thread cutting, which has a significant impact on the manufacturing costs.

Der Erfindung liegt die Aufgabe zugrunde, einen Fahrrad-Rahmen zu schaffender im Vergleich zu herkömmlichen Rahmen durch Art und Design auf automatische Fertigung ausgerichtet ist,und dadurch erhebliche Vorteile aufweist.The invention is based on the object of creating a bicycle frame which, in comparison to conventional frames, is geared towards automatic production by its type and design and thus has considerable advantages.

Diese Aufgabe wird durch einen Fahrrad-Rahmen gelöst, der gemäß der Erfindung gekennzeichnet ist durch zwei spiegelbildlich,aus Metallblech gefertigte und längs der Symmetrieebene miteinander verbundene Halbschalen,This object is achieved by a bicycle frame which, according to the invention, is characterized by two mirrored half-shells made of sheet metal and connected to one another along the plane of symmetry,
