Abstract

A pedal cycle type egometer is constructed such that the braking effect exerted against the subject using the egometer is applied by means of a hydraulic system and can be controlled and regulated. The hydraulic brake system consists of an oil circulation system with a tank, a pump driven by the foot pedals of the cycle type egometer, a manometer and a control valve. Drive from the pedals to the pump may be by chain or direct gear wheels. The hydraulic brake and drive system may be alternatively mounted in a pivoted cabin to allow operation of various angles of inclination.

Description

fahrrad - Ergometer Die Erfindung bezieht sich auf einen Fahrrad - Srgometer als medizinisches Arbeitsmeßgerät, das eine dosierbare Belastung zu Untersuchunszwecken ermöglicht.bicycle ergometer The invention relates to a bicycle Srgometer as a medical work measuring device that provides a metered load for examination purposes enables.

Es ist bekannt, daß die Belastung der Tretkurbel ( Abbremsung gegen den Prüfling ) durch einen getrennt erregten Gleichstromgenerator erfolgt. Die vom Generator abgegebene Leistung wird hierbei in einem mit Drehschalter stufenweise einstellbaren Widerstand umgewandelt. Die Konstanthaltung der Belastung im Bereich zwischen 45 und 75 Pedalumdrehungen pro Minute erfolgt dadurch, daß der Strom zur Peldwicklung des Generators durch einen Regulatorverstärker reguliert wird. Die vorhandenen Reibungsverluste werden hierbei durch einen zusätzlich eingespeisten, der Drehzahl proportionalen Strom kompensiert.It is known that the load on the crank (braking against the test item) is carried out by a separately excited direct current generator. The ones from The power output from the generator is gradually reduced in a rotary switch adjustable resistance converted. Keeping the load constant in the area between 45 and 75 pedal revolutions per minute takes place in that the current to the The field winding of the generator is regulated by a regulator amplifier. the Existing friction losses are hereby additionally fed in, the current proportional to the speed is compensated.

Solche lrgometer sind nur für exakte medizinische Untersuchungen geeignet und in der Anschaffung sehr teuer.Such ergometers are only suitable for precise medical examinations and very expensive to buy.

Für Trainingsmeßzwecke ist es auch schon bekannt, die erwünschte Abbremsung gegen den Prüfling mit Hilfe einer unter Federwirkung stehenden verstellbaren Bandbremse zu erzielen ( Reibungseffekt ). Solche Bandbremsen lassen aber z .B. schon durch tempebedingte Bremsveränderungen keine befriedigenden Ergebnisse zu ; sie sind weiterhin schadanfällig und müssen in gewissen Zeitabständen wegen erfolgter Veränderungen der ledern nachjustiert werden, Zwecks Erzielung einer nicht so kostspieligen und dennoch für exakte Messungen geeigneten Abbremsung gegen den Prüfling wird erfindungsgemäß eine hydraulische Bremse vo geschlagen, die einen gleichbleibenden Bremseffekt hat und eine genaue Kraftmessung zuläßt. Da das Meßgerät in diesem Falle nicht von der Reibung sondern vom Arbeitsdruck abhängt, ist eine genaue eichung des Fedaldruckes und des Meßgerätes möglich.For training purposes it is also already known the desired deceleration against the test object with the help of an adjustable band brake under spring action to achieve (friction effect). Such band brakes can, for example. already by tempo-related Brake changes do not produce satisfactory results; they are still prone to damage and have to be readjusted at certain intervals due to changes in the leather in order to obtain a not so costly yet accurate measurements According to the invention, suitable braking against the test object is hydraulic Brake vo struck, which has a constant braking effect and an accurate Force measurement allows. Since the measuring device in this case does not depend on the friction but depends on the working pressure, an exact calibration of the spring pressure and the measuring device is necessary possible.

Die hydraulische Bremse ist auch nicht schadenanfällig und ermöglicht eine kompakte Bauweise.The hydraulic brake is also not prone to damage and enables a compact design.

Das Wesen der erfindung wird darin erblickt, daß die Abbremsung gegen den Prüfling eiries Fahrrad-Ergometers hydraulisch, kontrollier- und regelbar erfolgt.The essence of the invention is seen in the fact that the deceleration against the test item eiries bicycle ergometer is hydraulic, controllable and adjustable.

Die hydraulische Bremse kann naturgemäß auch für Drehkurbel Ergometer ( für Beinbehinderte ) Anwendung finden.The hydraulic brake can naturally also be used for crank ergometers (for the handicapped).
