Abstract

In the pedal drive with a crank arm which is fastened on a shaft mounted in the device and at the free end of which a pedal is rotatably mounted, the pedal (8) is mounted rotatably on an adjustment device (3) arranged displaceably and fixably on the crank arm (1) so that, by individual adjustment of the length of each crank arm (1), an adaptation to the respective application, e.g. in the case of varying impairment of leg mobility, is possible. The pedal drive finds application for example in ergometers, bicycles and other devices operated by means of a tread crank. <IMAGE>

Description

Die Erfindung bezieht sich auf einen Pedalantrieb der im Oberbegriff des Patentanspruchs 1 angegebenen Gattung.The invention relates to a pedal drive the specified in the preamble of claim 1 Genus.

Bei solchen Geräten, die Ergometer, Fahrräder und andere durch Tretkurbel betriebene Geräte sein können, kommt es nicht selten vor, daß bei entsprechenden Behinderungen oder Ungleichheiten der Beine unterschiedlich lange Kurbelarme des Pedalantriebs zweckmäßig sind. Nun könnte sich ein Beinbehinderter ein Ergometer oder Rehabilitationsgerät speziell für seinen Bedarf anfertigen lassen, wodurch jedoch erhebliche Mehrkosten entstehen. Bei z.B. von vielen unterschiedlich beinbehinderten Patienten benutzten Ergometern, beispielsweise zum Zwecke der Erstellung eines EKG unter Belastung oder zum Zwecke der Bewegungstherapie, ist eine individuelle Einstellung der Kurbelarmlänge des Pedalantriebs nicht möglich, weil die serienmäßig hergestellten Geräte mit Kurbelarmen konstanter Länge ausgestattet sind. Dies trifft auch auf Fahrräder und sonstige pedalgetriebene Geräte zu.In such devices, the ergometer, bicycles and other devices operated by a crank, it is not uncommon for corresponding Disabilities or inequalities of the legs differ long crank arms of the pedal drive are appropriate. Now a legally handicapped person could get an ergometer or Make a rehabilitation device specifically for his needs leave, but this incurs significant additional costs. With e.g. by many different legally handicapped people Patients used ergometers, for example for the purpose the creation of an EKG under stress or for the purpose exercise therapy is an individual attitude the crank arm length of the pedal drive is not possible, because the mass-produced devices with crank arms constant length. This is also true towards bicycles and other pedal-driven devices.

Der Erfindung liegt die Aufgabe zugrunde, einen für den jeweiligen Anwendungsfall individuell anpaßbaren Pedalantrieb zu schaffen.The invention has for its object one for individually adaptable to the respective application To create pedal drive.

Diese Aufgabe wird erfindungsgemäß durch die Kennzeichnungsmerkmale des Patentanspruchs 1 gelöst. Zweckmäßige weitere Ausgestaltungen des erfindungsgemäßen Pedalantriebs sind den Unteransprüchen zu entnehmen.This object is achieved by the Characteristic features of claim 1 solved. Appropriate further refinements of the invention Pedal drives can be found in the subclaims.

Die Erfindung ermöglicht eine individuelle Einstellung der Kurbelarmlängen, auch rechts und links in unterschiedlichen Längen, und zwar von maximal bis praktisch Null, weil, wie aus der nachfolgenden Beschreibung eines Ausführungsbeispiels hervorgeht, die Verstellvorrichtung umsteckbar ist.The invention enables individual adjustment the crank arm lengths, also right and left in different lengths, from maximum to  practically zero because, as from the following Description of an embodiment emerges, the adjustment device can be changed over.

Die Zeichnung veranschaulicht das erwähnte Ausführungsbeispiel. Dabei zeigtThe drawing illustrates the above Embodiment. It shows

Fig. 1 eine Seitenansicht des Pedalantriebs und Fig. 1 is a side view of the pedal drive and

Fig. 2 eine Ansicht in Richtung des Pfeiles II in Fig. 1. Fig. 2 is a view in the direction of arrow II in FIG. 1.

Ein Kurbelarm (1) sitzt auf einer Welle (2), die in einem Gerät (Ergometer, Fahrrad o.dgl.) drehbar gelagert ist und den Antrieb auf das Gerät überträgt. Auf dem Kurbelarm (1) sitzt eine Verstellvorrichtung (3), die aus zwei Klemmplatten (4, 5) und zwei nicht dargestellte Klemmschrauben besteht und somit auf dem größten Teil der Länge des Kurbelarmes (1) stufenlos verstellbar ist.A crank arm ( 1 ) sits on a shaft ( 2 ), which is rotatably mounted in a device (ergometer, bicycle or the like) and transmits the drive to the device. On the crank arm ( 1 ) is an adjusting device ( 3 ), which consists of two clamping plates ( 4, 5 ) and two clamping screws, not shown, and is thus infinitely adjustable over most of the length of the crank arm ( 1 ).

Die eine (größere) Klemmplatte (4) weist eine Bohrung (6) für die Achse (7) eines Pedals (8) sowie zwei Schraubenbohrungen (9) für die Klemmschrauben auf, und die andere (kleinere) Klemmplatte (5) weist zwei Schraubenbohrungen (10) auf, die im montierten Zustand mit den Schraubenbohrungen (9) der einen (größeren) Klemmplatte (4) fluchten. Ferner weist die andere Klemmplatte (5) eine Nut (11) zur Aufnahme des Kurbelarmes (1) auf, an dem eine Anschlagkante (12) für die Verstellvorrichtung (3) vorgesehen ist.One (larger) clamping plate ( 4 ) has a hole ( 6 ) for the axis ( 7 ) of a pedal ( 8 ) and two screw holes ( 9 ) for the clamping screws, and the other (smaller) clamping plate ( 5 ) has two screw holes ( 10 ), which are in alignment with the screw holes ( 9 ) of one (larger) clamping plate ( 4 ). Furthermore, the other clamping plate ( 5 ) has a groove ( 11 ) for receiving the crank arm ( 1 ), on which a stop edge ( 12 ) is provided for the adjusting device ( 3 ).

Wie aus Fig. 1 unschwer zu erkennen ist, kann die Verstellvorrichtung (3) so umgesteckt werden, daß das Pedal (8) der Welle (2) zugewandt ist, so daß, wenn die Verstellvorrichtung (3) dann an der Anschlagkante (12) anliegt, eine Kurbelarmlänge von Null eingestellt ist.As can easily be seen from FIG. 1, the adjusting device ( 3 ) can be repositioned so that the pedal ( 8 ) faces the shaft ( 2 ), so that when the adjusting device ( 3 ) is then at the stop edge ( 12 ) is present, a crank arm length of zero is set.
