Abstract

The invention, by very simple and uncommonly cost-effective means, solves the problem of presenting a resistance to those training on a training apparatus for home sports purposes, medical and other training purposes. In particular this resistance is non-linear, i.e. it does not increase linearly but exponentially with the speed of the training. This is achieved in that the invention makes use of the hydraulic resistance of commercially available hydraulic shock absorbers, the shock absorbers, according to the disclosure of the invention, being arranged with an angular offset on a crank shaft so that the crank points on the circular path stand at an angle of 120 degrees to one another. In this way a smooth, uniform operation is achieved.

Description

Stand der TechnikState of the art

Aufgabe der Erfindung ist es, bei Trainingsgerateri uie Kraft so zu bremsen, daß ein möglicnst "naturlicher" widerstand entsteht. Es ist bekannt, daß beim Rudern die vom Trainierenden aufzubringende Kraft in der Potenz der Geschwindigkeit steht, mit der das Ruder @ewegt wird. Um bei Beimtrainern usw. dies zu silllulieren, ist derzeit großer Aufwand notwendig. Der naturliche kraft-Geschwindigkeitsverlauf wird dagegen bei preiswerten mechanischen Bremsen nur außerst unvollkommen nachgebildet. Daher ist die Aufgabe des erfindungsgemäßen Gedankens, das naturliche Ver-Verhältnis von Kraft und Geschwindigkeit bei geringem Kostenaufwand nachzubilden.The object of the invention is to increase the strength in training equipment brake that a possible "natural" resistance arises. It is known that When rowing, the force to be applied by the person exercising is expressed as the power of speed with which the rudder @ is moved. In order to simulate this with co-trainers etc., a lot of effort is currently required. The natural force-speed curve on the other hand, is only very imperfectly reproduced in inexpensive mechanical brakes. Therefore, the task of the idea according to the invention is the natural relationship of power and speed at low cost.

Erfindungsgemäße Losung Die Erfindung bedient sich der Tatsache, daß handelsübliche, hydraulische Stoßdämpfer eine Charakteristik aufweisen, die dem natürlicnen Verhaltnis von Kraft und Geschwindigkeit entspricht. Allerdings steht einer Anwendung die Tatsache entgegen, daß die Kraft kontinuierlich zu bremsen ist. Uer Weg der Stoßdampfer dagegen ist begenzt. Die erfindungsgemäße Losung bedient sich daher eines Kurbelbetriebes, um die (permanente) gerichtete Kraft eine Dreh@ewegung umzusetzen. Auf einer Kropfung der Kur@elwelle ist ein handelsublicher hyar. Stoßdämpfer angebracht. Drenwegungen werden so in Längstbewegungen ulilyesetzt, uie voin stoßdämpfer wirkungsvoll yebremst werden. Dabei ist die @remskraft vorteilhat abhangig von der Geschwindigkeit des Kurbeltriebes.Solution According to the Invention The invention makes use of the fact that Commercially available hydraulic shock absorbers have a characteristic that corresponds to the corresponds to the natural relationship between force and speed. However stands an application counteracts the fact that the force is to be braked continuously. The path of the shock absorber, on the other hand, is limited. The solution according to the invention serves therefore a crank operation, around the (permanent) directed force a rotary movement to implement. On a crop of the Kur @ elwelle is a commercially available hyar. Shock absorbers appropriate. Drenging movements are thus set into longest movements, uie voin shock absorbers be effectively slowed down. The braking force is advantageous depending on the Speed of the crank mechanism.

Nur bei einem Stoßdampfer wurde die Bremskraft nachteilig einen sinusformigen Verlauf haben.Only in the case of a shock absorber did the braking force disadvantageously become sinusoidal Have course.

Erfindungsgemäß wird daher oer Kurbelbetrieb so ausgebildet, daß drei Stoßdämpfer gegeneinander um 1ZU Grad versetzt angeordnet sind (Figur 1).According to the invention, therefore, oer crank operation is designed so that three Shock absorbers are arranged offset from one another by 1ZU degrees (Figure 1).

Auf oiese Art entsteht als resultierende dremskraft eine nanezu lineare bremskraft, ole im Quadrat der Drehgeschwindigkeit anwächst.In this way, the resulting braking force is too linear braking force, ole increases in the square of the rotational speed.

Dadurch ist vorteilhaft und auf einfache Weise der natürliche widerstand nachgebildet, der bei der Betatigung eines Ubungsgerätes entsteht. Vorteilhaft ist weiter, oau die belastung einfacti durch Anderung des Ubersetzungsverhältnisses an unterschiedliche Trainingsanforderungen angepaßt werder kann.This makes the natural resistance advantageous and simple simulated, which arises when operating an exercise device. Is beneficial Furthermore, the burden is also reduced by changing the transmission ratio can be adapted to different training requirements.
