Fig. 3 eine perspektivische Explosionsdarstellung der Pedalhebel-Abstandsverstellvorrichtung; Fig. 3 is an exploded perspective view of the pedal lever distance adjustment device;
Fig. 4 eine Draufsicht auf die Anordnung in Fig. 1.Fig. 4 is a plan view of the arrangement in Fig. 1.
Die in den Fign. 1 bis 4 dargestellte Pedalhebel-Abstandsverstellvorrichtung gemäß der vorliegenden Erfindung wird für einen Fahrradtrainer benutzt.The pedal lever distance adjusting device according to the present invention shown in Figs. 1 to 4 is used for a bicycle trainer.
Der Fahrradtrainer umfasst einen Rahmen 13, zwei Hinterräder 14, die jeweils am Rahmen 13 angebracht sind, zwei Pedalhebel 15, die jeweils an einer Pedaltragstange 20 angebracht sind, zwei Einweg-Klinkenräder 10, die jeweils an den Hinterrädern 14 angebracht sind, zwei Ketten 12, die jeweils um die Klinkenräder 10 laufen und jeweils an einem ersten Ende mit einem am Pedalhebel 15 befestigten Draht 16 und an einem zweiten Ende mit einer ebenfalls am Pedalhebel 15 befestigten Feder 11 &ngr; erbunden sind. Die beiden Ketten 12, denen jeweils eine Feder 11 und ein Draht 16 zugeordnet sind, werden von den beiden Pedalhebeln 15 des Fahrradtrainers betätigt, um den Rahmen 13 und die beiden Hinterräder 14 anzutreiben. The bicycle trainer comprises a frame 13, two rear wheels 14 each attached to the frame 13, two pedal levers 15 each attached to a pedal support rod 20, two one-way ratchet wheels 10 each attached to the rear wheels 14, two chains 12 each running around the ratchet wheels 10 and each connected at a first end to a wire 16 attached to the pedal lever 15 and at a second end to a spring 11 also attached to the pedal lever 15. The two chains 12, each associated with a spring 11 and a wire 16, are actuated by the two pedal levers 15 of the bicycle trainer to drive the frame 13 and the two rear wheels 14.
Auf diese Weise werden die Pedalhebel 15 von den Beinen des Benutzers nach vorne geschoben, um relativ zu den Pedaltragstangen 20 nach außen geschwenkt zu werden, und sie werden dann von der Rückholkraft der Feder 11 zurückgezogen. Auf diese Weise kann der Benutzer das Abbiegen und Strecken seiner Beine trainieren.In this way, the pedal levers 15 are pushed forward by the user's legs to be pivoted outward relative to the pedal support rods 20 and are then retracted by the return force of the spring 11. In this way, the user can practice bending and straightening his legs.
Die Pedalhebel-Abstandsverstellvorrichtung ist an dem Fahrradtrainer angebracht und besteht aus den beiden Pedaltragstangen 20, zwei Verstellrohren 30 und zwei Einsteckstiften 40.The pedal lever distance adjustment device is attached to the bicycle trainer and consists of the two pedal support rods 20, two adjustment tubes 30 and two insertion pins 40.
Jede der beiden Pedaltragstangen 20 ist mit einem Pedalhebel 15 schwenkbar verbunden und mit mehreren Durchgangslöchern 21 versehen. Jedes der beiden Verstellrohre 30 ist an dem vorderen Ende des Rahmens 13 des Fahrradtrainers befestigt. Die Verstellrohre 30 bilden in axialer Richtung jeweils einen Aufhahmekanal 31 zur gleitenden Aufnahme einer Pedaltragstange 20 und sind mit mehreren Durchgangslöchern 32 versehen, die jeweils mit dem Aufnahmekanal 31 in Verbindung steht und jeweils zu einem Durchgangsloch 21 der zugehörigen Pedaltragstange 20 ausrichtbar sind. Jeder der beiden Einsteckstifte 40 verläuft durch eines der Durchgangslöcher 32 des Verstellrohres 30, durch den Aufnahmekanal 31 des Verstellrohres 30 und ist in eines der Durchgangslöcher 21 der Pedaltragstange 20 eingesteckt, um die Pedaltragstange 20 an dem Verstellrohr 30 verstellbar zu sichern.Each of the two pedal support rods 20 is pivotally connected to a pedal lever 15 and is provided with a plurality of through holes 21. Each of the two adjustment tubes 30 is attached to the front end of the frame 13 of the bicycle trainer. The adjustment tubes 30 each form a receiving channel 31 in the axial direction for slidingly receiving a pedal support rod 20 and are provided with a plurality of through holes 32, each of which is connected to the receiving channel 31 and can each be aligned with a through hole 21 of the associated pedal support rod 20. Each of the two insertion pins 40 runs through one of the through holes 32 of the adjustment tube 30, through the receiving channel 31 of the adjustment tube 30 and is inserted into one of the through holes 21 of the pedal support rod 20 in order to adjustably secure the pedal support rod 20 to the adjustment tube 30.
Bei Benutzung lässt sich jede der beiden Pedaltragstangen 20 nach Entfernen des Einsteckstiftes 40 in dem Aufnahmekanal 31 des zugehörigen Verstellrohres 30 in Längsrichtung verstellen, um die Position des Pedalhebels 15 zwecks Anpassung an die Erfordernisse des Benutzers zu verstellen.In use, each of the two pedal support rods 20 can be adjusted longitudinally in the receiving channel 31 of the associated adjustment tube 30 after removal of the insertion pin 40 in order to adjust the position of the pedal lever 15 to suit the requirements of the user.
Auf diese Weise lässt sich der Abstand zwischen der Pedaltragstange 20 und dem Verstellrohr 30 in beliebiger Weise verstellen, so dass sich der Fahrradtrainer an Benutzer unterschiedlicher Statur anpassen lässt. Außerdem können sich die beiden Pedaltragstangen 20 relativ zu dem Verstellrohr 30 bewegen, so dass die beiden Pedalhebeltragstangen 20 und damit die beiden Pedalhebel 15 in unterschiedlichen Positionen angeordnet werden können (wie in Fig. 4 gezeigt), so dass der Fahrradtrainer von Personen mit unterschiedlich langen Beinen benutzt werden kann.In this way, the distance between the pedal support rod 20 and the adjustment tube 30 can be adjusted in any way so that the bicycle trainer can be adapted to users of different statures. In addition, the two pedal support rods 20 can move relative to the adjustment tube 30 so that the two pedal lever support rods 20 and thus the two pedal levers 15 can be arranged in different positions (as shown in Fig. 4), so that the bicycle trainer can be used by people with different leg lengths.
