Description
Fahrradgestell. Die gegenwärtig in Gebrauch stehenden Fahrradgestelle sind so gestaltet, dass für Herrenfahrräder und Damenfahrräder jeweils gesonderte Formen verwendet werden muss ten.
Zweck der vorliegenden Erfindung ist es nun, ein Gestell zu schaffen, das einheitlich für Herren- und Damenfahrräder verwendbar <B>ist.</B>
Dieser Zweck wird der Erfindung gemäss dadurch erreicht, dass das Fahrradgestell aus zwei sich kreuzenden Rohren besteht, wobei das den Sattel und das Tretkurbellager tra gende, kürzere Rohr mit dem am Vorderende die Lenkstange und am rückwärtigen, ge- gabelten Ende das Hinterrad aufnehmenden, längeren Rohr ein Stück bildet. Das kürzere Rohr kann aus zwei Teilstücken bestehen, die in ihrer Achsrichtung versetzt zueinander liegen können.
In der Zeichnung ist eine beispielsweise Ausführungsform eines Fahrradgestelles ge mäss der Erfindung dargestellt. Fig. 1 zeigt das zum Fahrrad ergänzte Gestell in Seitenansicht und Fig. 2 in Drauf sicht.
Während das gegenwärtig gebräuchliche, rahmenförmige Fahrradgestell aus sechs Rohr teilen besteht, von denen überdies noch zwei zu Gabeln ausgebildet sein müssen, weist das dargestellte Gestell nur zwei Rohre auf, die zur Aufnahme von Lenkstange, Hinter rad, Sattel und Tretkurbellager genügen. Als Haupttragorgan wirkt das starke Stahlrohr 1, dessen geweitetes Vorderende 2 mit einer Büchse zur Lagerung der mit der Vorder- radlenkgabel verbundenen Lenkstange ver sehen ist, während das Hinterende 3 ge gabelt ist zur Aufnahme des Hinterrades.
Ein senkrecht zur Achse des Haupttragrohres 1 in dieses eingesetztes kürzeres, etwas schwä cheres Rohr 4 dient zur Aufnahme des Sat tels 5 und trägt am Unterende das Tretkurbel lager 6.
Das beschriebene Fahrradgestell bringt gegenüber den üblichen Rahmengestellen naturgemäss eine bedeutende Material- sowie Arbeits- und Zeitersparnis bei der Herstel lung mit sich.
Ausserdem ist es als Einheitstype sowohl für Herren- wie Damenfahrräder verwendbar. Es sind schon früher ähnliche Gestelle vor geschlagen worden, die aber entweder dann, wenn das Haupttragorgan als Kastenträger ausgebildet war, viel zu teuer in der Her stellung waren, oder aber in anderer Aus führung und Zusammensetzung nicht die notwendige Festigkeit aufwiesen. Alle diese Mängel sind durch das beschriebene Gestell beseitigt, welches einfach in der Form und billig in der Herstellung ist und grösste Festigkeit und Widerstandsfähigkeit gegen Zerstörung aufweist.
Bicycle rack. The bicycle racks currently in use are designed in such a way that separate shapes have to be used for men's and women's bicycles.
The purpose of the present invention is now to create a frame that can be used uniformly for men’s and women’s bicycles
This purpose is achieved according to the invention in that the bicycle frame consists of two intersecting tubes, the shorter tube carrying the saddle and the pedal crank bearing, with the longer tube holding the handlebar at the front end and the rear wheel at the rear forked end Pipe forms one piece. The shorter tube can consist of two sections that can be offset from one another in their axial direction.
In the drawing, an example embodiment of a bicycle rack is shown according to the invention. Fig. 1 shows the frame supplemented to the bicycle in side view and Fig. 2 in plan view.
While the currently common, frame-shaped bicycle rack consists of six tube parts, of which two must also be designed to be forks, the frame shown has only two tubes that are sufficient to accommodate the handlebar, rear wheel, saddle and crank bearings. The main supporting element is the strong steel tube 1, the widened front end 2 of which is provided with a bushing for mounting the steering rod connected to the front wheel steering fork, while the rear end 3 is forked to accommodate the rear wheel.
A shorter, slightly weaker tube 4 inserted perpendicular to the axis of the main support tube 1 is used to accommodate the Sat means 5 and carries the crank bearing 6 at the lower end.
The bicycle frame described brings naturally a significant material, labor and time savings in the produc tion with it compared to the usual frame racks.
In addition, it can be used as a unit type for both men's and women's bicycles. Similar frames have been proposed before, but either when the main support member was designed as a box girder, they were far too expensive to manufacture, or in a different execution and composition did not have the necessary strength. All these deficiencies are eliminated by the frame described, which is simple in shape and inexpensive to manufacture and has the greatest strength and resistance to destruction.
