    ROBERT KNOLLER t\ WIEN.   Fussbremse für Fahrräder mit freien Tretkurbeln. 



   Die den Gegenstand vorliegender Erfindung bildende Fussbremse für   Fahrrader mit   freien Tretkurbeln besteht aus einem nahe der Kurbelwelle an dem Rahmen schwenkbar befestigten, mit beiderseitigem Auftritt versehenen Hebel, welcher mittels des nach einiwärts gedrohten Fussrücktheiles entgegen der Wirkung einer Feder derart verschwenkt worden kann, dass eine Bremswirkung auf das   Laufrad oder den Hoden ausgeübt wird.   



   In beiliegender Zeichnung sind mehrere   Ausführungsformen einer derartigen Fuss-   
 EMI1.1 
 die Bremswirkung durch   Niederdrücken   eines Hebels auf den Boden ausgeübt wird. 



   Wie aus Fig. 1 ersichtlich, ist nahe der Kurbelwelle a auf dem Rahmen b der Bremshebel c um d schwenkbar befestigt, welcher an seinem Ende mit beiderseitigem Auftritte   r versehen   und durch einen Lenker f mit dem Hebel g verbunden ist, Letzterer ist bei h an dem Rahmen schwenkbar befestigt und mit einem gebräuchlichen Bremsbacken 
 EMI1.2 
 welchem Falle die in Fig. 3 dargestellte Anordnung getroffen wird. 



   Soll die Fussbremse auf die Nabe des Laufrades einwirken, so wird, wie aus Fig. 4 ersichtlich, der Bremschebel c mit dem einen Ende eines um die Nabe o geschlungenen Bremsbandes p verbunden, dessen anderes Ende am Rahmen befestigt ist, so dass beim   Niederdrücken von   c das   Mrcmsband   fest an die Nabe angezogen wird.

   The subject of the present invention forming foot brake for bicycles with free pedal cranks consists of a pivotably attached to the frame near the crankshaft, provided with a step on both sides, which can be pivoted against the action of a spring against the action of a spring by means of the inwardly threatened footrest part exercised on the impeller or testicles.



   In the accompanying drawing, several embodiments of such a foot
 EMI1.1
 the braking effect is exerted by pressing a lever on the ground.



   As can be seen from Fig. 1, near the crankshaft a on the frame b, the brake lever c is pivotally mounted about d, which is provided at its end with mutual steps r and is connected by a link f to the lever g, the latter is at h pivotally attached to the frame and with a common brake shoe
 EMI1.2
 in which case the arrangement shown in Fig. 3 is made.



   If the foot brake is to act on the hub of the wheel, as can be seen in FIG. 4, the brake lever c is connected to one end of a brake band p looped around the hub o, the other end of which is attached to the frame, so that when the c the Mrcmsband is tightened firmly on the hub.
