Abstract

In an apparatus for controlling the running belt speed when running on a running belt with an adjustable angle of inclination, the central position of the runner is monitored and, as soon as the runner leaves his central position as a result of changes in the running speed, the central position is restored by a correction of the running belt speed. The ground contact is imparted to the runner by means of a video system. <IMAGE>

Description

Die Erfindung betrifft eine Vorrichtung zum Regeln der Laufbandgeschwindigkeit, die das Laufen auf einem Laufband mit veraenderbarer Lauflaechenneigung ermoeglicht, bestehend aus einem in Laengs- und Querrichtung in seiner Neigung verstellbaren Laufband, sowie einer rechnergesteuerten Mess- und Regeleinrichtung, die die von einem Bildgeber (Videoanlage) vorgegebenen Gelaendebilder in Laufbandneigungen umsetzt und die durch die Laufgeschwindigkeit des Laeufers auf das Laufband uebertragenen Kraefte mittels einer Bremseinrichtung so ausregelt, dass der Laeufer, ohne sich festzuhalten, mittig auf dem Laufband fixiert bleibt.The invention relates to a device for regulating Treadmill speed, which is running on a treadmill with changeable tread inclination, consisting of one in the longitudinal and transverse directions in its inclination adjustable treadmill, as well as one computer-controlled measuring and control device that the terrain images given by an imager (video system) translates into treadmill inclinations and the by the running speed of the runner on the Treadmill transferred forces by means of a braking device adjusted so that the runner, without himself to hold firmly, remains fixed in the middle on the treadmill.

Einfache Laufbaender, bei denen man sich beim Laufen an Griffen festhaelt, sind bekannt, ebenso sind motorisch angetriebene Laufbaender bekannt, auf denen der Laeufer mit der Geschwindigkeit des Bandes laufen muss.Simple treadmills where you can walk holds on handles are known, as are motor powered treadmills known on the Runners run at the speed of the belt got to.

Der Erfindung liegt die Aufgabe zugrunde, auf kleinem Raum das natuerliche Laufen im Gelaende mit variablen Gelaendeneigungen und Laufgeschwindigkeiten wirklichkeitsgetreu nachzuempfinden.The object of the invention is small Space the natural running in the area with variable Realistic terrain inclinations and running speeds to empathize.

Diese Aufgabe wird erfindungsgemaess dadurch geloest, dass die durch die Laufgeschwindigkeit des Laeufers erzeugte entgegengesetzte Laufbandgeschwindigkeit bei beliebiger Bandneigung und Bandgeschwindigkeit korrigierbar ist. Durch die Wechselwirkung - Messen und Korrigieren - wird dem Laeufer das Laufuntergrundgefuehl des freien Gelaendes vermittelt und zum anderen wird dadurch der Abstand vom Laeufer zum Gelaendebildgeber (Fernsehgeraet) konstant gehalten. Die Position des Laeufers muss sich zwischen zwei im festen Abstand zueinander angeordneten, beruehrungsfrei arbeitenden Sensoren befinden. Verlaesst der Laeufer seine mittige Position - weil er schneller oder langsamer laeuft -, so wird dieser neue Zustand ueber den jeweiligen Sensor einem Steuerrechner mitgeteilt, der dann in Abhaengigkeit von der Laufbandneigung, der Laufbandgeschwindigkeit und dem Koerpergewicht des Laeufers solange Geschwindigkeitskorrekturen ueber eine Bremseinrichtung vornimmt bis sich der Laeufer wieder in der mittigen Position befindet und folgedessen Laeufer - und Laufbandgeschwindigkeit wieder im Betrag gleich gross sind.According to the invention, this object is achieved by that by the running speed of the runner generated opposite treadmill speed at any belt inclination and belt speed can be corrected is. Through the interaction - measuring and Correct - the runner will feel the running surface of the free area and to the other  the distance from the runner to the terrain imager (TV set) kept constant. The position The runner must be between two in the solid Distance from each other, working without contact Sensors. Leaves the runner its central position - because it is faster or slower runs - so this new state is over the communicated each sensor to a control computer which then depending on the incline of the treadmill, the Treadmill speed and body weight Runs as long as speed corrections a braking device makes until the runner is again in the central position and as a result Runner - and treadmill speed again in Amount is the same.

Wie schon angesprochen, wird die Laufbandgeschwindigkeit beim Verlassen der Laufbandmitte korrigiert. Diese Korrekturen muessen ruckfrei aber ausreichend schnell durchgefuehrt werden, da sonst der Laeufer sein Gleichgewicht verliert bzw. die Laufbandbegrenzungen ueberlaeuft. Aus diesem Grunde erfasst der Steuerrechner fortwaehrend Laufbandneigung und Laufbandgeschwindigkeit, um in Abhaengigkeit von dem Koerpergewicht des Laeufers optimale Bremsmanoever ausfuehren zu koennen.As already mentioned, the treadmill speed is corrected when leaving the center of the treadmill. These corrections must be smooth but sufficient be carried out quickly, otherwise the runner loses its balance or the treadmill limits overflows. For this reason, the Control computer continuously treadmill incline and treadmill speed, to depending on body weight run optimal braking maneuvers to be able to.

Die zur Einstellung der Laufbandneigungen und Bremskraefte verwendeten Stellantriebe koennen in beliebiger Form ausgebildet sein. Bei der vorliegenden Vorrichtung zum Regeln der Laufbandgeschwindigkeit wird vorgeschlagen, dass die Einstellungen mit elektrisch angesteuerten Schubspindelantrieben vorgenommen werden. The one for setting the treadmill inclinations and braking forces Actuators can be used in any Form be formed. In the present device to control the treadmill speed suggested that the settings with electrical controlled thrust spindle drives.  

Einem weiteren Gedanken der Erfindung gemaess ist die Abspielgeschwindigkeit des Gelaendebildgebers (Videoanlage) veraenderbar. Hierzu wird der vorher von einem Laeufer waehrend einem Gelaendelaufes mit einer Kamera aufgezeichnete, die Gelaendeansichten enthaltende Bildtraeger (Videoband), dessen Tonspur zur Synchronisation mit dem Steuerrechner mit Informationen ueber die Laufbandneigungen versehen wurde, durch der Laufbandgeschwindigkeit proportionale Steuersignale schneller oder langsamer abgespielt.Another idea of the invention is Playback speed of the terrain imager (video system) changeable. For this purpose, the one previously Runner during a cross-country race with a Camera recorded containing terrain views Image carrier (video tape), the soundtrack for Synchronization with the control computer with information about the incline of the treadmill control signals proportional to the treadmill speed played faster or slower.

Ein Verfahren zum Regeln der Laufbandgeschwindigkeit, wobei die Messung und Auswertung wie vorab beschrieben vorgenommen werden kann, ist insbesondere beim Einsatz zur Rehabilitation nach Operationen, Herzinfarkten, etc. anwendbar. Eine an den Steuerrechner anschliessbare Messonde zur Erfassung der Herzfrequenz ermoeglicht die Ueberwachung des Patienten und loest die Warnung von Patient und Arzt aus. Die Laufleistungen koennen zur Beurteilung des Genesungsfortschrittes herangezogen werden.A method of controlling treadmill speed the measurement and evaluation as described above can be made is particularly during use for rehabilitation after operations, heart attacks, etc. applicable. One that can be connected to the control computer Measuring probe for recording the heart rate possible monitoring the patient and resolving the Warning from patient and doctor. The mileage can be used to assess the progress of recovery be used.
