Description

  

  Vorrichtung zur Schmierung der     gurbellager    von Fahrrädern.    Die vorliegende Erfindung betrifft eine  Vorrichtung zur Schmierung der Kurbel  lager von Fahrrädern, bei welcher ein in  Nachbarschaft der Kurbelachse liegender  Hohlteil des Fahrradgestelles als Ölbehälter  ausgebildet und das Öl aus demselben mit  Hilfe eines Fördermittels den Lagern der  Kurbelachse     zuführbar    ist.  



  Die Zeichnung veranschaulicht zwei       Ausführungsbeispiele    des Erfindungsgegen  standes.  



       Fig.    1 zeigt eines derselben '     ,Schnitt     und       Fig.    2     in        Anwendung;          Fig.    3 zeigt das zweite Beispiel.  



  Die hohle     Sattelstützstrebe    a des Fahr  radgestelles     (Fig.    1 und 2) ist im untern  Teil als Ölbehälter ausgebildet. In     deusel-          ben    ragt eine Röhre b hinein, in welcher  ein Docht c steckt, dessen freier Teil in das  Ölbad im Behälter hinabtaucht. Durch den  Docht c, der am untern Ende der Röhre b  in zwei Röhrchen d sich verzweigt, wird    das vom Docht angesaugte<B>01</B> durch die  Röhrchen<I>d</I> den Kugellagern<I>f</I> der Kurbel  achse     g    zur Schmierung zugeführt.  



  Das von der     Kugellagerschmierung    her  rührende überschüssige Öl sammelt sich im  Unterteil der     Kurbellagerhülse    h, von wo es  durch ein schräg nach hinten gerichtetes  Röhrchen<I>i</I>     (Fig.    1 und 2) der Triebkette<I>k</I>  des Fahrrades zur Schmierung derselben  zugeleitet werden kann.  



  Bei der Ausführungsform der     Fig.    3  wird das<B>01</B> aus dem als Ölbehälter aus  gebildeten     untern    Teil der     Sattelstützstrebe    a  bei der Fahrt zwangsweise . zugeführt. Die  Röhre     b',    deren Wandung hier mit Löchern       b2    versehen ist, enthält eine drehbare     Förder-          schraube        m,,    welche in dem Sinne umge  dreht wird, dass sie das ihr zugeleitete Öl  mittelst der Röhrchen d den Lagern     f    der  Kurbelachse g zuführt.

  Device for lubricating the crank bearings of bicycles. The present invention relates to a device for lubricating the crank bearings of bicycles, in which a hollow part of the bicycle frame located in the vicinity of the crank axis is designed as an oil container and the oil from the same can be fed to the bearings of the crank axis with the aid of a conveyor.



  The drawing illustrates two exemplary embodiments of the subject matter of the invention.



       Fig. 1 shows one of the same ', section and Fig. 2 in use; Fig. 3 shows the second example.



  The hollow seat post a of the driving wheel frame (Fig. 1 and 2) is designed in the lower part as an oil tank. A tube b protrudes into deuselben, in which a wick c is inserted, the free part of which dips into the oil bath in the container. The wick c, which branches into two tubes d at the lower end of the tube b, is used to transfer the <B> 01 </B> sucked in by the wick through the tubes <I> d </I> to the ball bearings <I> f < / I> supplied to the crank axle g for lubrication.



  The excess oil from the ball bearing lubrication collects in the lower part of the crank bearing sleeve h, from where it flows through a small tube (Fig. 1 and 2) of the drive chain <I> k </ I which is directed obliquely backwards > the bicycle can be fed to lubricate the same.



  In the embodiment of FIG. 3, the <B> 01 </B> from the lower part of the seat support strut a, which is formed as an oil container, is compulsorily while driving. fed. The tube b ', the wall of which is provided here with holes b2, contains a rotatable delivery screw m ,, which is turned in the sense that it feeds the oil fed to it by means of the tube d to the bearings f of the crank axis g.

   The feed screw m is driven by means of a pair of bevel gears n from the crank axis g.
