Description

Pedalarmkurbel üblicher Bauart weisen eine Länge von 172,5–175 – max. 180 mm auf. Die Hebelkraft ist bei der jeweils gewählten Länge immer gleichbleibend.Pedalarmkurbel more usual Type have a length from 172.5 to 175 - max. 180 mm up. The leverage is always the same at the selected length.

Der in den Schutzansprüchen (1–8) angegebenen Erfindung liegt das Problem zugrunde einen Pedalkurbelarm zu erschaffen, der sich in der Vorwärts-Drehbewegung automatisch um 20 mm verlängert, um eine grössere Kraftübertagung (Drehmoment) zu erreichen.Of the in the protection claims (1-8) indicated invention, the problem is based on a pedal crank arm to create itself in the forward-rotary motion automatically lengthened by 20 mm, a bigger one About force meeting To reach (torque).

Gleichzeitig soll der ergonomische Bewegungsablauf des Körpers nicht unterbrochen werden.simultaneously The ergonomic movement of the body should not be interrupted.

Mit der Erfindung wird erreicht, dass ein geringerer Kraftaufwand erforderlich ist. Der Radfahrer, insbesondere der Radsportler spart Körperenergie ein, was eine erhöhte Ausdauerkraft zur Folge hat.With The invention is achieved that a lower force required is. The cyclist, especially the cyclist, saves body energy, what an increased Endurance power.

Bei niedrigem Puls wird eine höhere Geschwindigkeit erreicht! (kein Doping mehr) Ein Schubstange mit Schwalbenschwanzführung (10A) mit der eingeschraubter Pedale (11) wird
nach vorn abwärts geschoben. Bei der folgenden, rückwärtigen Aufwärtsbewegung zieht sich
die Pedale vom unteren Totpunkt beginnend wieder kreisförmig bis zum oberen Totpunkt hin
zurück, um dann in Folge wiederum nach vorn elliptisch weiter zu drehen.At low pulse, a higher speed is achieved! (no more doping) A push rod with dovetail guide ( 10A ) with the pedals ( 11 ) becomes
pushed forward downwards. At the following, backward upward movement is taking place
starting from bottom dead center, the pedals return circular to top dead center
back, then turn elliptical turn in turn forward again.

Die um 20 mm elliptische Drehbewegung kommt dem ergonomischen Bewegungsablauf des Menschen sehr entgegen, zumal der Mensch in seiner Gehbewegung nach vorn ausgerichtet ist.The By 20 mm elliptical rotation comes the ergonomic movement very contrary to man, especially as man in his walking motion is aligned to the front.

Die elliptische Drehbewegung des Bewegungsablaufs kommt dadurch zu Stande, dass eine Abtastrolle (3) eine feststehende, elliptische Kurbelscheibe (4) bei jeder Pedalumdrehung umläuft und dabei den oberen und unteren Totpunkt abtastet. Die elliptiche Bewegung wird vom menschlichen Körper nicht störend war genommen.The elliptical rotational movement of the movement sequence comes about through the fact that a cam follower ( 3 ) a fixed, elliptical crank disc ( 4 ) rotates every time the pedal rotates, scanning the top and bottom dead centers. The elliptical movement is not disturbed by the human body.

Bei diesem System ist eine zwangsweise Vorschubrichtung der Pedale (11) gewährleistet. Es kommt zu keinerlei Verklemmungen im Pedalvorschubbereich (12), wie es bei anderen Vorschubarten bekannt ist! Es handelt sich um eine echte Revolution im Antriebsbereich bei Fahrrädern.In this system is a forced feed direction of the pedals ( 11 ) guaranteed. There is no jamming in the pedal feed area ( 12 ), as it is known with other types of feed! It is a real revolution in the field of driving bicycles.
