Beschreibung:Description:
Die Erfindung bezieht sich auf eine Verlängerung der Tretkurbeln von Fahrrädern, wodurch die Hebelwirkung beim Niedertreten gesteigert wird. Im unbelasteten Zustand wird die Verlängerung angewinkelt. Dadurch kann bei gleichem Kraftaufwand und gleich langem Weg eine wesentlich höhere Geschwindigkeit erzielt werden.The invention relates to an extension of the cranks of bicycles, whereby the leverage is increased when treading. In the unloaded condition, the extension is angled. As a result, a much higher speed can be achieved with the same effort and the same long distance.
Der Erfindung liegt somit die Aufgabe zugrunde, bei gleich bleibendem Kraftaufwand die Hebelwirkung der Tretkurbel beim Niedertreten mit einfachen konstruktiven Mitteln wesentlich zu steigern, wobei aber der vom Pedal zurückzulegende Weg gleich bleibend ist. Die erhöhte Hebelwirkung kommt praktisch nur beim Niedertreten zum Tragen. Bei der Aufwärtsbewegung des Pedals wird die Verlängerung angewinkelt, wodurch ein halbellipsenformiger Kreis bei der Umdrehung entsteht.The invention is therefore the object of substantially increasing the leverage of the pedal when depressing with simple structural means with constant effort, but the distance traveled by the pedal path is the same. The increased leverage comes in handy only when slumping. As the pedal is raised, the extension is angled, creating a semi-elliptical circle during rotation.
Im unbelasteten Drehbereich wird der Verlängerungshebel der Tretkurbel mittels einer Stahlfeder angewinkelt, beziehungsweise zurückgezogen. Die Stahlfeder bewirkt beim Niedertreten auch einen gleichmäßig ansteigenden Druck auf die Tretkurbel.In the unloaded turning range, the extension lever of the pedal crank is bent or retracted by means of a steel spring. The steel spring also causes a steadily increasing pressure on the pedal crank when pedaling.
An der Verlängerung der Tretkurbel sind zur Begrenzung der variablen Winkelstellung zwei Stehbolzen angebracht.At the extension of the pedal crank two stud bolts are mounted to limit the variable angular position.
Alternativ kann die herkömmliche Tretkurbel mit dem Verlängerungshebel mit einem Gelenk, in dem der Winkel vorgegeben werden kann, verbunden werden. Ein Einbau der Rückholfeder in das Gelenk wäre auch denkbar.Alternatively, the conventional crank with the extension lever can be connected to a joint in which the angle can be specified. An installation of the return spring in the joint would also be conceivable.
In der Zeichnung ist der Erfindungsgegenstand beispielsweise dargestellt. +In the drawing, the subject invention is shown, for example. +
