Vorrichtung zur Erzeugung einer Kraft für die Betätigung einer TretradbremseDevice for generating a force for operating a pedal brake

Die Neuerung betrifft eine Vorrichtung gemäß dem Oberbegriff des Schutzanspruches.The innovation concerns a device according to the generic term of the protection claim.

Aufgabe zur Neuerung ist, eine Vorrichtung zu schaffen, mit der die Erzeugung der für die Betätigung der Felgen-, Trommel- oder Scheibenbremsen von Treträdern erforderlichen Kraft mittels Rückwärtsdrehung der Pedalkurbeln erfolgt.The aim of the innovation is to create a device with which the force required to operate the rim, drum or disc brakes of pedal bikes is generated by means of backward rotation of the pedal cranks.

Diese Aufgabe wird neuerungsgemäß durch die Merkmale a und b des Schutzansspruches gelöst.According to the innovation, this task is solved by features a and b of the protection claim.

Die Neuerung eignet sich für alle Typen von herkömmlicherweise handbetätigten Tretradbremsen und ersetzt die am Lenker angebrachten Bremshandhebel und die jeweils kraftübertragenden Seilzüge durch eine Vorrichtung, die den bewährten "Rücktritt" für das Bremsen auch für Felgen-, Trommel- und Scheibenbremsen verfügbar werden läßt.The innovation is suitable for all types of conventionally hand-operated pedal brakes and replaces the brake levers attached to the handlebars and the power-transmitting cables with a device that makes the tried-and-tested "backpedal" braking available for rim, drum and disc brakes.

Der neuerungsgemäße Hebelarm bildet mit der Achse ein Drehrichtgesperre in Gestalt eines Zahn- oder eines Klemmrichtgesperres. Konstruktiv sind alle Ausführungen derartiger Gesperre in geeigneter Form innerhalb und außerhalb des Tretlagergehäuses in Verwirklichung der Neuerung gemeint und sollen unter Schutz gestellt sein.The lever arm according to the innovation forms a rotational locking mechanism with the axle in the form of a toothed or clamping locking mechanism. In terms of construction, all versions of such locking mechanisms in a suitable form inside and outside the bottom bracket housing are intended to implement the innovation and should be protected.

Die Figur zeigt eine im Inneren des Tretlagergehäuses angeordnete neuerungsgemäße Vorrichtung. Die dem Betrachter zugewandten Hälften des Tretlagergehäuses und der Tretachse sowie die linke (hier vordere) Tretkurbel sowie der vordere Bremshebel der dargestellten Hinterradfelgenbremse sind der Übersicht wegen fortgelassen.The figure shows a device according to the innovation arranged inside the bottom bracket housing. The halves of the bottom bracket housing and the pedal axle facing the viewer as well as the left (here front) pedal crank and the front brake lever of the rear wheel rim brake shown have been omitted for the sake of clarity.
