Abstract

The training machine consists of a moving belt (7) which operates at a speed controlled by the user of the machine. The control consists of a rotatable cone which is mounted with its axis horizontal. A first cable (2) is wound around the largest diameter of the cone and is subjected to a tensile force. A second cable (4) is wound around a spiral groove formed in the conical surface and has a weight (8) fastened to its free end. The resultant force on the cone causes it to rotate, together with a signal generator (6). ADVANTAGE - The machine is self-regulating.

Description

Die Erfindung betrifft eine Laufbandsteuerung, für die bewegungs­ spezifische Ergometrie aller Sportarten die auf dem Laufband realisierbar sind.The invention relates to a treadmill control for the movement specific ergometry of all sports on the treadmill are realizable.

Es ist bekannt, einen Probanden auf dem Laufband über einen Seilzug mit einer Kraftmeßdose zu verbinden und im Seilzug ein elastisches Glied, beispielsweise eine Zugfeder oder Gummizug, anzuordnen. Mit dieser Vorrichtung ist lediglich eine Restkraftmessung möglich, da nur die Kraft gemessen wird, die zusätzlich zur Überwindung des Bewegungswiderstandes erforderlich ist.It is known to test a subject on a treadmill Connect the cable to a load cell and insert it into the cable elastic link, for example a tension spring or elastic band, to arrange. With this device is only one Residual force measurement possible because only the force is measured that required in addition to overcoming the resistance to movement is.

Bekannt ist weiterhin eine Belastungsvorrichtung die am Körper des Probanden über einen Seilzug befestigt ist, an dessen anderem Ende über eine Umlenkrolle auswechselbare Massen angeordnet sind. Allen bekannten Ergometern ist als gemeinsamer Nachteil anhängig, daß keine Leistungsvorgabe bei unterschiedlicher Geschwindigkeit möglich ist.Also known is a loading device on the body of the Subject is attached via a cable, at the other end Exchangeable masses are arranged via a deflection roller. All known ergometers have a common disadvantage, that no performance specification at different speeds is possible.

Ableitend aus diesen, für die bewegungsspezifische Ergometrie bedeutsamen Nachteil, ergibt sich die Aufgabe eine Laufband­ steuerung zur Verfügung zu stellen, die eine Leistungsvorgabe bei frei wählbarer Geschwindigkeit auf dem Laufband ermöglicht.Derived from these, for exercise-specific ergometry significant disadvantage, the task arises of a treadmill to provide control that has a performance target enabled at freely selectable speed on the treadmill.

Erfindungsgemäß wird diese Aufgabe gelöst durch eine Kegelschnecke bestehend aus einem Kegelkern mit darauf angeordneter Wendel an deren größten Durchmesser ein Zugseil angreift, die Kegel­ schnecke umschließt und über ein elastisches Zwischenglied mit dem Probanden in Wirkverbindung steht.According to the invention, this object is achieved by a conical screw consisting of a cone core with a spiral arranged on it at its largest diameter a traction rope attacks the cones snail encloses and with an elastic intermediate link the subject is in active connection.

Es gehört auch zur Erfindung, daß in der Mitte der Kegellänge auf dem Kegelkern ein zweites Zugseil befestigt ist, an dem eine auswechselbare Masse hängt und stirnseitig an der Kegelschnecke ein Geber angeordnet ist, der mit dem Laufbandantrieb verbun­ den ist.It is also part of the invention that in the middle of the cone length on the cone core, a second pull rope is attached to which one interchangeable mass hangs and on the face of the conical screw an encoder is arranged, which is connected to the treadmill drive that is.

Auch gehört zur Erfindung, daß als Alternative zur Kegelschnecke eine Induktionskupplung Verwendung findet, deren Geber vom Zugseil umschlossen und sowohl den Erregerstrom in der Induktionskupplung als auch die Drehzahl des Laufbandantriebes steuert.Also part of the invention is that as an alternative to the conical screw an induction coupling is used, the encoder from Traction rope enclosed and both the excitation current in the Induction clutch as well as the speed of the treadmill drive controls.

AusführungsbeispielEmbodiment

Die Erfindung soll beispielhaft anhand beiliegender Zeichnungen erläutert werden. Es zeigen:The invention is intended to serve as an example with reference to the accompanying drawings are explained. Show it:

Fig. 1 Seitenansicht der Laufbandsteuerung, Fig. 1 side view of the treadmill control,

Fig. 2 Anordnung der Induktionskupplung. Fig. 2 arrangement of the induction coupling.

Mit 1 ist die Wirkrichtung des Zugseiles 2 dargestellt. Das Zugseil 2 umschließt die Kegelschnecke 3 und ist am größten Durchmesser der Kegelschnecke 3 befestigt. Ein weiteres Zugseil 4 ist in der Mitte der Kegellänge am Kegelkern befestigt und liegt somit zwischen der Wendel 5 der Kegelschnecke 3. Am anderen Ende des Zugseils 4 ist eine Masse 8 auswechselbar befestigt. Der Geber 6 ist stirnseitig an der Kegelschnecke 3 angeordnet und steht mit dem Laufbandantrieb 7 in Verbindung. Mit 9 ist der Hebelarm bezeichnet, der sich aus der jeweiligen Stellung der Kegelschnecke 3 , dem höchsten Auflagepunkt des Zugseils 4 an dem Kegelkern und der Kegelschneckenachse theoretisch ergibt.With 1 the direction of action of the pull rope 2 is shown. The traction cable 2 surrounds the conical screw 3 and is attached to the largest diameter of the conical screw 3 . Another traction cable 4 is fastened to the cone core in the middle of the cone length and is therefore located between the helix 5 of the cone screw 3 . At the other end of the traction cable 4 , a mass 8 is fastened exchangeably. The encoder 6 is arranged on the end of the conical screw 3 and is connected to the treadmill drive 7 . 9 with the lever arm is referred to, which theoretically results from the respective position of the conical screw 3 , the highest point of contact of the traction cable 4 on the cone core and the conical screw axis.

10 ist das elastische Zwischenglied im Zugseil 2 und 11 die Induktionskupplung. 10 is the elastic intermediate link in the pull rope 2 and 11 the induction coupling.

Die Wirkungsweise der Erfindung ist folgende:
Wenn 1 durch Leistung des Probanden sich nach vorn bewegt, dreht sich die Kegelschnecke 3 durch das Seil 2 in Pfeilrichtung. Dadurch wird das Seil 4 auf die Kegelschnecke 3 innerhalb der Windung 6 gezogen. Durch die Drehung der Kegelschnecke 3 wird der Geber 6 verstellt und dadurch die Drehzahl des Motors erhöht - das Laufband läuft schneller. Dadurch wird das, von der Masse 8 beaufschlagte Seil 4 in den Bereich des kleineren Durchmessers der Kegelschnecke 3 gezogen. Damit gelangt das Zugseil 4 in den Bereich des kleineren Durchmessers auf dem Kegelkern, der Hebelarm 9 wird verkürzt und die entstehende Kraft aus Hebelarm mal Kraft (gebildet von der Masse 8) verringert sich, so daß das Produkt aus Kraft mal Geschwindigkeit konstant gehalten wird. Zur Dämpfung der höherfrequenten Bewegungsanteile des Probanden wird in das Seil 2 ein elastisches Glied 10 (Gummi, Feder) eingeschaltet.The operation of the invention is as follows:
When 1 moves forward due to the performance of the subject, the conical screw 3 rotates through the rope 2 in the direction of the arrow. As a result, the rope 4 is pulled onto the conical screw 3 within the turn 6 . The encoder 6 is adjusted by the rotation of the conical screw 3 , thereby increasing the speed of the motor - the treadmill runs faster. As a result, the rope 4 acted upon by the mass 8 is pulled into the region of the smaller diameter of the conical screw 3 . This pulls the traction cable 4 into the area of the smaller diameter on the cone core, the lever arm 9 is shortened and the force arising from lever arm times force (formed by mass 8 ) is reduced, so that the product of force times speed is kept constant. In order to dampen the higher-frequency parts of the subject's movement, an elastic member 10 (rubber, spring) is switched into the rope 2 .

Ein weiteres Ausführungsbeispiel besteht darin, daß der Angriffspunkt des Seiles 2 mit dem Geber 6 verbunden ist, der mit einer Induktionskupplung 11 in Wirkverbindung steht. Der Geber 6 steuert sowohl den Laufbandantrieb 7 als auch die Induktionskupplung 11. Another embodiment is that the point of application of the rope 2 is connected to the transmitter 6, which is in operative connection with an induction coupling 11 . The transmitter 6 controls both the treadmill drive 7 and the induction clutch 11 .

Die Wirkungsweise dieses Ausführungsbeispieles ist folgende:The operation of this embodiment is as follows:

Wenn 1 sich nach vorn bewegt, verstellt sich der Geber 6 und erhöht die Drehzahl des Laufbandantriebs 7. Außerdem wird der Erregerstrom der Induktionskupplung 11 so verringert, daß das Produkt aus Kraft mal Geschwindigkeit (Leistung) konstant gehalten wird.When 1 moves forward, the encoder 6 adjusts and increases the speed of the treadmill drive 7 . In addition, the excitation current of the induction coupling 11 is reduced so that the product of force times speed (power) is kept constant.
