Abstract
Description
Die Erfindung betrifft ein Fahrrad, das mit Trethebeln angetrieben wird. Dieses besitzt drei Räder bei geringen Abmessungen, so dass es z. B. im PKW mitgeführt und auch als Sportgerät in der Wohnung genutzt werden kann.The invention relates to a bicycle, that is powered by pedal levers. This has three wheels small dimensions, so that it is e.g. B. carried in a car and also as sports equipment can be used in the apartment.
Die gattungsgemäßen Fahrräder werden als Trethebel- oder Stepprad bezeichnet. Im Unterschied zu den üblichen Fahrrädern wird die Antriebsbewegung nicht über zwei Pedale an umlaufenden Kurbelarmen eingeleitet, sondern über zwei einseitig gelagerte Hebel. Die Auf- und Abbewegung wird über verschiedene Getriebekonstruktionen in eine Drehbewegung des Antriebsrades umgewandelt. Dieser Antrieb ist aufwendiger als ein direkter Kurbeltrieb, besitzt aber einige Vorteile. So kann das Körpergewicht der Person besser eingesetzt werden (kein Radfahrerrundrücken)und das ungünstige Krafthebelverhältnis im Bereich des Kurbelarmtotpunktes entfällt. Die Gelenkbelastung wird dadurch verringert und der mögliche höhere Körpereinsatz wirkt gesundheitlich positiv.The generic bicycles are called pedal levers or Step wheel called. In contrast to the usual bicycles the drive movement does not over two pedals initiated on rotating crank arms, but via two levers on one side. The up and down movement is different Gear designs converted into a rotary motion of the drive wheel. This drive is more complex than a direct crank drive but some advantages. So the body weight of the person can be better are used (no cyclist back) and the unfavorable power lever ratio in the The area of the crank arm dead center is omitted. The joint load will thereby reducing and the possible higher physical exertion has a positive health effect.
Räder
mit dieser Antriebsart sind als übliche Fahrräder (Zweiräder) ausführbar. Gemäß der
Steppräder an sich besitzen keinen
Sattel. Die Person steht hier wechselweise auf einer Tretfläche mit
Hebelarm. Um das seitliche Kippmoment bei der Belastung des Pedalhebels
auszugleichen sind diese Steppräder
häufig
als Dreiräder
ausgeführt
(
Aufgabe der Erfindung ist es, ein Steppfahrrad zu schaffen, dass klein, leicht und trotzdem kippsicher ist, sowie effektive Hebelverhältnisse und damit eine gute Kraftübertragung besitzt.The object of the invention is a Quilted bike to create that small, light and yet tip-proof is, as well as effective leverage ratios and therefore a good power transmission has.
Die Aufgabe wird gemäß den Merkmalen des Anspruchs 1 gelöst. Durch diese Ausgestaltung wird ein kleines Steppfahrrad geschaffen. Der am Halbrahmen um eine horizontale Achse drehbar gelager te Pendelrahmen, am Halbrahmen drehbar gelagerte Hebelarme und daran gelagerte Trethebel mit Antriebsrad ermöglicht eine hohe Kippsicherheit. Die Einleitung der Gegenkraft zum Körpergewicht und Kettenzug erfolgt in tiefer Ebene auf das jeweilige Hinterrad. Dadurch ist keine Kippbewegung mit dem Körper auszugleichen. Der kleine Radabstand ermöglicht eine geringe Gesamtabmessung. Das Steppfahrrad ist deshalb gut zu transportieren, z. B. im PKW-Kofferraum. Eine Nutzung in Räumen als Sportgerät ist einfach durch ein Stützrollenpaar für das Vorderrad möglich.The task is performed according to the characteristics of claim 1 solved. This configuration creates a small step bike. The pendulum frame, which is rotatably mounted on the half frame around a horizontal axis, lever arms rotatably mounted on the half frame and pedal levers attached to them with drive wheel a high level of safety against tipping. The initiation of the counterforce to body weight and chain hoist takes place in a low level on the respective rear wheel. This means that no tilting movement can be compensated for with the body. The small Wheelbase allowed a small overall dimension. The step bike is therefore good too transport, e.g. B. in the car trunk. Use in rooms as sports equipment is simply through a pair of support rollers for the Front wheel possible.
Die vorteilhafte Gestaltung der Kraftübertragung von den Trethebeln und über Freilauf sichert die Nutzung im optimalen Hebelbereich.The advantageous design of the power transmission from the pedal levers and over Freewheel ensures the use in the optimal lever range.
Weitere besonders günstige Ausbildungen der Neuerung sind in den Unteransprüchen dargelegt.Other particularly favorable training courses Innovations are in the subclaims explained.
BeispieleExamples
Nachfolgend soll die Erfindung an einem Ausführungsbeispiel näher erläutert werden.The invention is intended to be described below an embodiment are explained in more detail.
Ein Vorderrad, entsprechend einem üblichen Fahrrad,
ist nicht lenkbar in der Vordergabel gelagert. In gedachter Verlängerung
der Vordergabel ist ein Rohr über
eine Strebe als Lenkeraufnahme
Etwa mittig am vorderen Rohr des
Halbrahmens
Bei der Benutzung des Steppfahrrades
erfolgt eine wechselweise Belastung der Pedale
Das Steppfahrrad kann somit entsprechend den individuellen Kräften und des Gewichtes sowie den Wünschen der Benutzer betrieben werden.The quilted bike can thus be the individual powers and the weight as well as the wishes the user operated.
Weitere Ausführungsvarianten im Rahmen der Erfindung sind möglich, ohne die Erfindung zu verlassen.Other design variants within the Invention are possible without leaving the invention.
