Fahrradrahmen nach neuesten medizinischen ErkenntnissenBicycle frames based on the latest medical findings

Fahrräder üblicher Bauart sind mit Einfachrohrrahmen in verschiedenen · ·Bicycles of common design are with single tube frames in various · ·

Rahmenhöhen aufgebaut. &Idigr;...&Idigr;.Frame heights built. &Idigr;...&Idigr;.

Zur Erlangung der notwendigen Festigkeit werden beim Herrenrad Vorzugs- *.,To achieve the necessary strength, men's bikes are equipped with preferential *.,

weise Diamantrahmen eingesetzt, die durch ihre Dreieckkonstruktion und die Dicke der verwendeten Rohre die erforderliche Steifigkeit sicherstellen. Diamond frames are used, which ensure the necessary rigidity through their triangular construction and the thickness of the tubes used.

Der im Schutzanspruch angegebenen Erfindung liegt das Problem zugrunde, einen Fahrradrahmen zu konstruieren, der eine gleichwertige oder bessere Seitenstabilität zur Vermeidung von Flatterneigung hat und der im Sitzrohr federnd Fahrbahnstöße absorbiert ohne Verwendung zusätzlicher Federgabeln und Federhinterschwingen.The invention specified in the protection claim is based on the problem of constructing a bicycle frame that has equivalent or better lateral stability to avoid fluttering and that absorbs road shocks in the seat tube without using additional suspension forks and suspension rear swing arms.

Dieses Problem wird gelöst mit den im Schutzanspruch aufgeführten Merkmalen des geschwungenen Doppelrohrrahmens, der bei Ausübung von Stößen durch Fahrbahnunebenheiten das Oberrohr des Rahmens bedingt durch das Körpergewicht des Radfahrers nach unten durchbiegt.This problem is solved with the features listed in the protection claim of the curved double tube frame, which, when impacts are exerted by uneven road surfaces, causes the top tube of the frame to bend downwards due to the body weight of the cyclist.

Mit den im Schutzanspruch 2 aufgeführten Merkmalen wird durch die Radstandvergrößerung und Vergrößerung des Vorderradvorlaufs sowohl das Federverhalten verbessert als auch der Geradeauslauf positiv beeinflußt.With the features listed in claim 2, the wheelbase extension and the front wheel caster increase both improve the suspension behavior and have a positive effect on straight-line stability.

Die Verstrebung der Doppelrohre ist derart ausgeführt, daß Bedienelemen- ·..' te für z.B. den Dynamo ohne Verletzungsgefahr angebaut worden sind und *··The bracing of the double tubes is designed in such a way that operating elements for the dynamo, for example, can be installed without risk of injury and *··

daß durch die Seitenverkleidung eine Kammer für Zubehör geschaffen wurde. · ##;# Darüberhinaus ist eine seitliche Verwindung des Rahmens durch die Quer- :...!. streben minimiert. *that the side paneling creates a chamber for accessories. · ## ; # In addition, lateral twisting of the frame is minimized by the cross braces. *

Mit der Erfindung wird erreicht, daß das Fahrrad auf ebenen (Asphalt) Strecken schnell ohne Flatterneigung bewegt werden kann und auf unebenen Strecken (Waldwege) stoßabsorbierend und trotzdem richtungsstabil gefahren wird.The invention ensures that the bicycle can be moved quickly on flat (asphalt) roads without any tendency to wobble, and that it can be ridden on uneven roads (forest paths) in a shock-absorbing but still directionally stable manner.

Bin Ausführungsbeispiel der Erfindung wird anhand der Zeichnung erläutert wobei der Rahmen (1) durch Einbau von Seitenverstärkungen (2) und von Querverstrebungen (3) sowie integrierten Bedienelementen (4) die federnden Eigenschaften erhält. Der Einbau von Zubehör oder auch Funktionseinheiten wie z.B. Standlichtautomatik ist in (5) dargestellt.An embodiment of the invention is explained using the drawing, where the frame (1) is given its springy properties by installing side reinforcements (2) and cross braces (3) as well as integrated control elements (4). The installation of accessories or functional units such as automatic parking lights is shown in (5).

1. Fahrradrahmen dadurch gekennzeichnet, daß die verbindenden Rohre zwisehen hinteren Ausfallenden, Sattelstützrohr und Steuerkopf doppelt ausgeführt sind mit einem Bogen im oberen Bereich, der ein Durchfedern des Oberrahmenrohres vorsieht.1. Bicycle frame characterized in that the connecting tubes between the rear dropouts, seat post tube and steering head are double with a curve in the upper area, which provides for a springing of the upper frame tube. 2. Fahrradrahmen nach Schutzanspruch 1 dadurch gekennzeichnet, daß sich der Steuerkopfwinkel durch die Durchbiegung des Oberrahmenrohres verkleinert und damit der Radstand vergrößert wird sowie der Vorlauf vergrößert. 2. Bicycle frame according to protection claim 1, characterized in that the steering head angle is reduced by the bending of the upper frame tube and thus the wheelbase is increased and the lead is increased. 3. Fahrradrahmen nach Schutzanspruch 1 dadurch gekennzeichnet, daß die Doppelrohre verstrebt sind und darin Bedienungselemente und Zubehör aufgenommen werden.3. Bicycle frame according to claim 1, characterized in that the double tubes are braced and control elements and accessories are accommodated therein. Griesheim, 31.10.1994Griesheim, 31.10.1994
