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.
