Abstract
Description
Die Erfindung betrifft ein Fortbewegungsmittel, insbesondere ein Fahrrad, das vor allem durch Muskelbewegung eines Menschen in Bewegung versetzt wird. The invention relates to a means of transportation, in particular a bicycle, the front everything is set in motion by a person's muscle movement.
Muskelbetriebene Fahrräder sind allgemein bekannt und werden in der Regel durch Kettenantriebe betrieben. Hierbei wird die Kraft auf mindestens eine Pedale übertragen welche über eine Kette das Hinterrad kontinuierlich antreibt. Muscle powered bicycles are well known and are usually used by Chain drives operated. This applies the force to at least one pedal transmitted which continuously drives the rear wheel via a chain.
Diese konventionelle Art und Weise der Kraftübertragung ist keineswegs als optimal zu bezeichnen. Sinn und Zweck der Erfindung ist also eine deutliche Verbesserung der Wirkungsgradkette von Muskelbewegung eines Menschen zur Kraftübertragung auf die Fahrbahn zu erzielen. This conventional way of power transmission is by no means optimal to call. The purpose of the invention is therefore a significant improvement the chain of efficiency of a person's muscle movement for power transmission to achieve on the road.
Die Lösung dieser Aufgabenstellung wird nachfolgend und in den Patentansprüchen beschrieben; außerdem findet die Erklärung anhand von Fig. 1 und Fig. 2 statt. The solution to this problem is described below and in the claims; also finds the explanation with reference to FIG. 1 and FIG. 2 instead.
In Fig. 1 ist ein erfindungsgemäßes, primär durch Muskelbewegung eines Menschen angetriebenes Fahrrad dargestellt. In Fig. 1 shows an inventive, primarily driven by muscle movement of a human bicycle is shown.
Mit 1 ist das grössere der beiden Kettenräder bezeichnet. Es ist fest mit der Antriebswelle A verbunden. Im Ausführungsbeispiel handelt es sich um ein einfaches Zweirad, mit hier nicht gezeigtem Vorderrad und Hinterrad. Mit 2 ist eine konventionelle Kette bezeichnet. Es könnte auch ein anderes Zugmittel sein, z. B. ein Zahnriemen. With 1 the larger of the two sprockets is designated. It is firmly connected to the drive shaft A. In the exemplary embodiment, it is a simple two-wheeler, with a front wheel and rear wheel not shown here. 2 is a conventional chain. It could also be another traction device, e.g. B. a toothed belt.
Erfindungsgemäss wird das Fahrrad über mindestens einen Hebelmechanismus 4 angetrieben, welchem eine oder mehrere Pedale 5 angegliedert sein kann/können. Der Hebel ist über einen bestimmten Winkel hin- und herschwenkbar (wie gezeichnet). Im gezeigten Ausführungsbeispiel wird die Hebelbewegung durch die festen Anschläge 7 begrenzt. Ein nicht gezeichnetes elastisches Element, insbesondere Feder kann dabei helfen den Hebel 4 wieder in die Ausgangsposition zu holen (Bei Fussschnallen nicht unbedingt erforderlich). Für diesen skizzierten Bewegungsablauf ist an der Nabe A ein Freilauf 6 erforderlich. Mit der Abtriebsnabe Z ist das Kettenzahnritzel 3 fest verbunden und in Drehrichtung beweglich. Hier lässt sich auch eine Mehrgangschaltung integrieren. According to the invention, the bicycle is driven via at least one lever mechanism 4 , to which one or more pedals 5 can be attached. The lever can be swiveled back and forth over a certain angle (as shown). In the exemplary embodiment shown, the lever movement is limited by the fixed stops 7 . An elastic element (not shown), in particular a spring, can help to bring the lever 4 back into the starting position (not absolutely necessary with foot buckles). For this sketched sequence of movements, a freewheel 6 is required on the hub A. With the output hub Z, the sprocket 3 is firmly connected and movable in the direction of rotation. A multi-speed gearbox can also be integrated here.
Auf die Darstellung weitergehender Merkmale (z. B. Bauteile zur Verkehrssicherheit o. ä.) wird hier aus Gründen der Übersichtlichkeit verzichtet. The presentation of further features (e.g. components for traffic safety etc.) is omitted here for reasons of clarity.
Der Drehmomentenverlauf eines konventionellen Kettenantriebes a unterscheidet sich markant vom erfindungsgemässen Drehmomentenverlauf b: Bei der Erfindung kann beispielsweise bereits im Ausgangszustand ein Drehmoment erzeugt werden, d. h. es gibt keine Totpunkte mehr, Fig. 2. The torque curve of a conventional chain drive a differs markedly from the torque curve b according to the invention: With the invention, for example, a torque can already be generated in the initial state, ie there are no more dead centers, FIG. 2.
Auch lässt sich - je nach Fahrgefühl - eine verkürzte Hubbewegung erzielen; oder es lassen sich links- und rechtsseitige Pedale gleichzeitig betätigen. Depending on the driving experience, a shortened lifting movement can also be achieved; or it left and right pedals can be operated simultaneously.
Erfindungsgemässes Fahrrad erhöht somit die Individualität des/der Einzelnen sehr stark. The bicycle according to the invention thus greatly increases the individuality of the individual strong.
Im Ergebnis ist erfindungsgemäßes Aggregat einfach im Aufbau, kostengünstig in der Fertigung und effektiv in seiner Wirkung. Es lässt sich überall dort sehr gut betreiben, wo muskelbewegte Transportmittel zum Einsatz gelangen sollen. As a result, the unit according to the invention is simple in construction, inexpensive in the manufacture and effective in its effect. It can be done very well anywhere operate where muscle-moving means of transport are to be used.
