Abstract

A boom (11) can be attached to a column (2) at any height and with variable inclination. A foot support (15, 16) is arranged displaceably on the boom and can be displaced along the boom (11) against the force of the pull cable (8). A loading unit (4) exerts an effect on the pull cable (8) and can be programmed by means of an operating device (21) in order to preselect the characteristics of the loading. Another boom can optionally be attached for arm exercises. A very wide variety of possible exercises can thus be selected with one apparatus, without its being necessary for any weights or mechanisms to be adjusted on the apparatus. Various booms (11) can be provided, by means of which the apparatus can be converted for various types of exercise, for example leg exercises, arm exercises or torso exercises. <IMAGE>

Dieses bekannte Gerät weist weitgehende Möglichkeiten der Gestaltung bzw. Wahl von Trainingsprogrammen, d. h. von Kraft-Weg-Charakteristiken und Bewegungsgeschwindigkeiten auf. Das Gerät dient jedoch nur dem Armtraining und bietet daher beschränkte Einsatzmöglichkeiten.The present invention relates to a strength or muscle training device according to the preamble of claim 1. Such a device is known from WO 91/07214. This known device has extensive options for designing or choosing training programs, i. H. of force-displacement characteristics and movement speeds. However, the device is only used for arm training and therefore offers limited uses.

Aus der WO 88/01185 ist auch ein Trainingsgerät bekannt, an welchem Angriffsorgane für Beintraining oder Armtraining wahlweise auf einer horizontalen Liegefläche oder an einer vertikalen Wand angebracht werden können.

Mit einem Fuss 1 ist eine Säule 2 mit rechteckigem Querschnitt und einer Reihe von Löchern 3 verbunden. Die Säule 2 dient gemäss Fig. 5 der Befestigung an einer Wand. Mit dem oberen Ende der Säule 2 ist ein Gehäuse 4 verbunden, in welchem sich ein Motor zur Erzeugung der Belastung befindet. Dieser Motor 5 ist in Fig. 2 dargestellt. Er wirkt entweder direkt oder über ein Getriebe 6 auf eine Seilwelle 7, die mit einer schraubenförmigen Seilrille versehen ist. Diese Seilrille dient dem einlagigen geordneten Aufwickeln eines Zugseils 8 mit einer Kraft bzw. einer Geschwindigkeit, die vom Motor 5 bestimmt ist.With a foot 1, a column 2 is connected with a rectangular cross section and a series of holes 3. According to FIG. 5, the column 2 is used for fastening to a wall. With the upper end of the column 2, a housing 4 is connected, in which a motor for generating the load is located. This motor 5 is shown in FIG. 2. It acts either directly or via a gear 6 on a cable shaft 7 which is provided with a helical cable groove. This rope groove serves the single-layer ordered winding of a traction cable 8 with a force or a speed that is determined by the motor 5.

Auf der Säule 2 ist eine Schelle 9 vertikal verschiebbar, und sie kann mittels eines Stiftes 10, der durch die Schelle in eines der Löcher 3 greift, in beliebiger Höhe an der Säule festgestellt werden. Mit der Schelle 9 ist ein Ausleger 11 in einem gewissen Bereiche schwenkbar und mittels eines Stiftes 12 in einer bestimmten Neigungslage feststellbar verbunden. Am äusseren Ende des Auslegers ist ein Teller 13 befestigt, welcher dem Auflegen des Auslegers auf einen Stuhl, auf ein Patientenbett oder dergleichen dient, und auf welchen der Patient oder die trainierende Person sich setzen kann. Auf dem Ausleger 11 ist ein Schlitten 14 verschiebbar, auf welchem ein Fusshalter 15 mit Bändern 16, welche mittels Klettenverschlüssen eng an den Fuss oder Schuh angelegt werden können, über eine Pendelstütze 17 mit einstellbarer Steifigkeit angebracht ist. Das Ende des Zugseils 8 greift am Schlitten 14 an und ist über eine Umlenkrolle 18 am Ausleger 11, eine Umlenkrolle 19 und eine im Fuss 1 untergebrachte Umlenkrolle zum Belastungsaggregat 4 bzw. auf die Seilwelle 7 geführt. Das Zugseil 8 kann auch ohne Umlenkrolle 18 direkt am Schlitten 14 angreifen, wenn zum Training Zugkräfte statt Druckkräfte ausgeübt werden sollen. Der Ausleger 11 kann von der Schelle 9 trennbar oder mit der Schelle von der Säule abnehmbar sein.On the column 2, a clamp 9 is vertically displaceable, and it can be fixed at any height on the column by means of a pin 10 which engages through the clamp in one of the holes 3. With the clamp 9, a boom 11 can be pivoted in a certain range and can be fixed in a certain inclination position by means of a pin 12. A plate 13 is attached to the outer end of the arm, which serves to place the arm on a chair, on a patient bed or the like, and on which the patient or the exercising person can sit. On the boom 11, a carriage 14 is slidable, on which a foot holder 15 with straps 16, which can be placed close to the foot or shoe by means of Velcro fasteners, is attached via a pendulum support 17 with adjustable stiffness. The end of the traction cable 8 engages on the carriage 14 and is guided to the loading unit 4 or to the cable shaft 7 via a deflection roller 18 on the boom 11, a deflection roller 19 and a deflection roller accommodated in the foot 1. The traction cable 8 can also engage directly on the slide 14 without a deflection roller 18 if tensile forces instead of compressive forces are to be exerted for training. The boom 11 can be separated from the clamp 9 or can be removed from the column with the clamp.

Auf einem Ständer 20 befindet sich ein Bedienungsgerät 21 mit einem Bildschirm 22 und verschiedenen Bedienungselementen, insbesondere einem Lautstärkeregler 23, mit Pfeilen versehenen Tasten 24 zur Wahl bestimmter Menues oder Parameter zur Anzeige auf dem Bildschirm 22 sowie eine Taste (+) 25 sowie eine Taste (-) 26. Ferner ist eine Start-Stop-Taste 27 sowie ein Bedienungsknopf 28 zur Notausschaltung des Gerätes vorgesehen. Die Funktionen der einzelnen Bedienungselemente wird später mit Hilfe des elektrischen Schaltschemas näher erläutert.On a stand 20 there is an operating device 21 with a screen 22 and various operating elements, in particular a volume control 23, arrows 24 provided with arrows for selecting certain menus or parameters for display on the screen 22 as well as a key (+) 25 and a key (-) 26. Furthermore, a start-stop key 27 and an operating button 28 are provided for the emergency shutdown of the device. The functions of the individual controls will be explained in more detail later using the electrical circuit diagram.

Das Bedienungsgerät 21 ist an der Säule 20 mittels einer Schelle 29 befestigt, welche mittels eines Spannhebels 30 gelöst bzw. festgezogen werden kann, um die Schelle 29 und damit das Bedienungsgerät 21 am Ständer 20 zu verstellen, und in der gewünschten Höhe und Richtung festzuklemmen. Das Bedienungsgerät 21 ist ausserdem mittels eines Bügels 31 in einer Spannzange 32 gehalten. Bei gelöster Spannzange 32 kann die Neigung des Bedienungsgerätes gewählt und dann die Spannzange wieder festgezogen werden. Es ist daher möglich, durch geeignete Positionierung des Ständers 20 und Verstellen des Bedienungsgerätes 21 eine ständige Beobachtung und eventuell Bedienung durch die trainierende Person zu ermöglichen. Das Bedienungsgerät 21 ist mittels eines Kabels 33 mit den übrigen Geräteteilen verbunden.The operating device 21 is fastened to the column 20 by means of a clamp 29, which can be loosened or tightened by means of a clamping lever 30 in order to adjust the clamp 29 and thus the operating device 21 on the stand 20 and to clamp it in the desired height and direction. The operating device 21 is also held in a collet 32 by means of a bracket 31. When the collet 32 is released, the inclination of the operating device can be selected and then the collet can be tightened again. It is therefore possible, by suitable positioning of the stand 20 and adjustment of the operating device 21, to enable constant observation and possibly operation by the training person. The operating device 21 is connected to the other device parts by means of a cable 33.

In den Figuren 4 und 5 sind entsprechende Teile gleich bezeichnet, wie in den Figuren 1 - 3. Das in den Figuren 4 und 5 dargestellte Gerät unterscheidet sich vom Gerät gemäss Fig. 1 lediglich durch einen etwas anders gestalteten Ausleger 34. Der Ausleger 34 ist zwar ebenfalls gegenüber der Schelle 9 schwenkbar und in verschiedenen Neigungen feststellbar, wie in Fig. 5 angedeutet ist. Fig. 5 zeigt im übrigen den Anbau des Gerätes an eine Wand 35. Aus Fig. 5 ist ersichtlich, dass der Ausleger in verschiedener Höhe und Neigung angebracht werden kann. Das Zugseil 8 ist an diesem Ausleger 34 über eine innere Umlenkrolle 19 und um eine von zwei äusseren Umlenkrollen 36 geführt. Am freien Ende des Zugseils 8 kann ein beliebiges Angriffsorgan, beispielsweise eine Stange für das Armtraining oder eine Art Joch für das Rumpftraining angebracht werden. Es kann also im wesentlichen ein und dasselbe Gerät lediglich mit zwei relativ einfachen unterschiedlichen Auslegern für die verschiedenartigsten Trainigsarten ausgerüstet und programmiert werden.In FIGS. 4 and 5, corresponding parts are identified in the same way as in FIGS. 1-3. The device shown in FIGS. 4 and 5 differs from the device according to FIG. 1 only by a somewhat differently designed arm 34. The arm 34 is although also pivotable relative to the clamp 9 and lockable in different inclinations, as indicated in Fig. 5. Fig. 5 shows the rest of the attachment of the device to a wall 35. From Fig. 5 it can be seen that the boom can be attached at different heights and inclinations. The pull cable 8 is guided on this bracket 34 via an inner deflection roller 19 and around one of two outer deflection rollers 36. At the free end of the pull rope 8, a any attack organ, for example a rod for arm training or a kind of yoke for trunk training. Essentially, one and the same device can only be equipped and programmed with two relatively simple different arms for the most varied types of training.

Wie die Figuren 4 und 5 zeigen ist am unteren Ende der Säule 2 im Fuss 1 des Gerätes ein Spannmotor 37 untergebracht, welcher auf die untere Umlenkrolle 38 dauernd ein gewisses Drehmoment ausübt und damit das auf die Seilwelle 7 auflaufende Trumm des Zugseils 8 unter einer gewissen Vorspannung hält, so dass stets ein sauberes einlagiges Aufwickeln des Zugseils gewährleistet ist. Der Umlenkrolle 38 kann eine Druckrolle 39 zugeordnet sein, welche das Zugseil 8 gegen die Umlenkrolle 38 anlegt, so dass auch bei im übrigen unbelastetem Zugseil stets die erwähnte Vorspannung im auf die Seilwelle 7 auflaufenden Trumm des Zugseils herrscht.As FIGS. 4 and 5 show, a tensioning motor 37 is accommodated in the foot 1 of the device at the lower end of the column 2, which continuously exerts a certain torque on the lower deflection roller 38 and thus the run of the traction cable 8 running onto the cable shaft 7 under a certain amount Preload holds, so that a clean single-layer winding of the pull rope is always guaranteed. The deflecting roller 38 can be assigned a pressure roller 39 which places the traction cable 8 against the deflecting roller 38, so that, even when the traction cable is otherwise unloaded, the aforementioned pretension always prevails in the run of the traction cable running onto the cable shaft 7.

Figur 6 zeigt das elektrische Schaltschema des Gerätes, wobei die dargestellten Schaltkreise nur teilweise beschrieben werden, soweit aus dem Schema ihre Funktion nicht direkt ersichtlich ist. In Fig. 6 ist unterschieden zwischen denjenigen Stromkreisen, die sich in den Geräteteilen 1 und 4 befinden, und denjenigen Stromkreisen, welche sich im Bedienungsgerät 21 befinden. Dem Belastungsmotor 5 ist eine Endstufe 40 zugeordnet, welcher verschiedene Steuersignale zugeführt werden. Die Steuerung erfolgt zum Teil auch indirekt über einen Vierquadrantenregler 41, welchem ebenfalls bestimmte Regelsignale zugeführt werden. Mit dem Motor 5 bzw. mit der Seilwelle 7 ist ein Encoder 42 verbunden, welcher die Position des Motors bzw. der Seilwelle 7 an einen Mikroprozessor 43 im Steuergerät 21 übermittelt. Dem Spannmotor 37 wird über eine Konstantstromquelle 44 ein konstanter Strom zugeführt, dem die konstante Vorspannung im Seil 8 entspricht. Beide Motoren 5 und 37 sind vorzugsweise als Gleichstrommotoren mit Permanentmagnetfeld ausgeführt, so dass ihr Drehmoment praktisch proportional ist dem Motorstrom. Der Regler 41 regelt dabei den Motor 5 insbesondere auf einen Stromsollwert bzw. DrehmomentSollwert oder einen Drehzahl-Sollwert bzw. Geschwindigkeitsollwert und zwar bezüglich eines ihm zugeführten Strom-Istwertes bzw. einer aus dem Encodersignal gewonnenen Ist-Drehzahl. Ein Bremchopper 45 verhindert das übermässige Ansteigen der Zwischenkreisspannung, wenn der Motor beim Herausziehen des Seils generatorisch betrieben wird. Die Bremsfunktion des Motors 5 wird durch den Mikroprozessor 43 angesteuert. Es ist eine Ueberwachungsschaltung 46 vorgesehen, welche bei Fehlfunktionen der Elektronik eine automatische Abschaltung vornimmt. Es ist ferner ein Tongenerator 47 vorgesehen, welcher über den Verstärker und Regler 23 einen Lautsprecher 48 speist. Es können dabei verschiedenartige Grössen akustisch signalisiert werden, beispielsweise kann die Tonhöhe der momentanen Geschwindigkeit mit welcher das Angriffsorgan des Gerätes betätigt wird entsprechen. Im Gerät kann auch ein Pegelwandler 49 vorgesehen sein, welcher über eine passende Schnittstelle den Anschluss des Bedienungsgerätes, beispielsweise an einen Personal Computer 50, und damit die Abspeicherung ganzer bestimmter Programme erlaubt. Entsprechende Speicherkapazität und Speichermöglichkeiten können allerdings auch im Bedienungsgerät selbst vorgesehen sein, so dass bestimmte Trainingprogramme, beispielsweise einem bestimmten Patienten zugeordnete Programme, gewählt werden können und nicht stets wieder neu programmiert werden müssen.FIG. 6 shows the electrical circuit diagram of the device, the circuits shown being only partially described, insofar as their function is not directly apparent from the diagram. In FIG. 6, a distinction is made between those circuits which are located in device parts 1 and 4 and those circuits which are located in operating device 21. An output stage 40 is assigned to the load motor 5, to which various control signals are supplied. In some cases, control is also carried out indirectly via a four-quadrant controller 41, to which certain control signals are likewise supplied. With the motor 5 or with the cable shaft 7, an encoder 42 is connected, which the position of the motor or the cable shaft 7 to one Microprocessor 43 in control unit 21 is transmitted. A constant current is supplied to the tensioning motor 37 via a constant current source 44, to which the constant pretension in the cable 8 corresponds. Both motors 5 and 37 are preferably designed as DC motors with a permanent magnetic field, so that their torque is practically proportional to the motor current. The controller 41 regulates the motor 5 in particular to a current setpoint or torque setpoint or a speed setpoint or speed setpoint, specifically with respect to an actual current value supplied to it or an actual speed obtained from the encoder signal. A brake chopper 45 prevents the DC link voltage from rising excessively when the motor is operated as a generator when the cable is pulled out. The braking function of the motor 5 is controlled by the microprocessor 43. A monitoring circuit 46 is provided which performs an automatic shutdown in the event of malfunctions in the electronics. A tone generator 47 is also provided, which feeds a loudspeaker 48 via the amplifier and controller 23. Different sizes can be acoustically signaled, for example the pitch can correspond to the instantaneous speed with which the attacking organ of the device is actuated. A level converter 49 can also be provided in the device, which allows the control device to be connected via a suitable interface, for example to a personal computer 50, and thus to save entire specific programs. Corresponding storage capacity and storage options can, however, also be provided in the operating device itself, so that specific training programs, for example programs assigned to a specific patient, can be selected and do not always have to be reprogrammed.

Das Programmieren des Gerätes wird allerdings erheblich erleichtert durch eine bestimmte Menuetechnik. So kann beispielsweise nach dem Einschalten des Gerätes zuerst entschieden werden, ob ein isokinetisches oder ein isotonisches Training programmiert werden soll. Entsprechend erscheinen dann auf dem Bildschirm 22 Anweisungen zur Einstellung der verschiedenen Parameter. Bei isotonischem Training wird zuerst angezeigt, dass die Zugkraft gewählt werden sollte. Mittels der Tasten 25 und 26 kann dann die Zugkraft erhöht oder vermindert und bei Anzeige der gewünschten Zugkraft mittels einer der Tasten 24 weitergeschaltet werden, womit die Zugkraft eingespeichert ist. Es wird dann beispielsweise nach der Einstellung der Bremskraft verlangt, was wiederum mittels der Tasten 25 und 26 erfolgen kann. Sodann wird nach dem Kraftverlauf bzw. der Kraft-Wegcharakteristik gefragt, wobei das Menue gemäss Fig. 7 angezeigt wird. Wiederum kann dann mittels der Tasten 25 und 26 die entsprechende Nummer angewählt und beim Weiterschalten eingespeichert werden. Wie Fig. 7 zeigt, sind dabei die verschiedensten Charakteristiken möglich, z. B. konstante Kraft gemäss Kurve 1 oder linear ansteigende oder abfallende Kraft gemäss Kurven 4 oder 5, usw. Selbstverständlich sind die Charakteristiken gemäss Fig. 7 nur als Beispiele zu verstehen, und es sind beliebige andere Charakteristiken durchaus möglich. Nach erfolgter Wahl der Charakteristik können noch die Zykluszeit und die Anzahl Zyklen gewählt und abgespeichert werden. Ausserdem können die Umkehrpunkte der Bewegung bestimmt und eingespeichert werden. Zu diesem Zweck kann das Angriffsorgan, also beispielsweise der Fusshalter gemäss Fig. 1, bei schwach angesteuertem Belastungsmotor aus der Nullstellung bei ganz aufgewickeltem Seil in eine erste Umkehrposition gezogen werden. Der Encoder 42 meldet diese Position dem Mikroprozessor und sie kann dann beispielsweise durch Drücken der Taste 25 eingespeichert werden. Dann kann der Fusshalter weiter in die zweite Umkehr- oder Anschlagposition gebracht werden und diese Position kann entsprechend eingespeichert werden. Damit ist das Gerät programmiert und kann zum Training eingeschaltet werden. In entsprechender Weise können andere Trainingstypen gewählt werden, beispielsweise isokinetisches Training, in welchem Falle die Geschwindigkeit, die Kraft und die Anzahl Zyklen vorgewählt werden können. Wie oben erwähnt, können dann auch die Umkehr- oder Anschlagpunkte festgesetzt werden, worauf das Gerät zum Betrieb bereit ist.Programming the device is made considerably easier by a certain menu technology. For example, after switching on the device, a decision can first be made whether to program isokinetic or isotonic training. Instructions for setting the various parameters then appear accordingly on the screen 22. In the case of isotonic training, it is first displayed that the traction should be selected. The buttons 25 and 26 can then be used to increase or decrease the tensile force and, when the desired tensile force is displayed, to be switched on using one of the buttons 24, whereby the tensile force is stored. It is then required, for example, for the braking force to be set, which in turn can be carried out using the buttons 25 and 26. Then the question of the force curve or the force-displacement characteristic is asked, the menu according to FIG. 7 being displayed. Again, the corresponding number can be selected using the keys 25 and 26 and stored when switching on. As shown in FIG. 7, a wide variety of characteristics are possible, for. B. constant force according to curve 1 or linearly increasing or decreasing force according to curves 4 or 5, etc. Of course, the characteristics according to FIG. 7 are only to be understood as examples, and any other characteristics are quite possible. After the characteristic has been selected, the cycle time and the number of cycles can be selected and saved. In addition, the reversal points of the movement can be determined and stored. For this purpose, the attack member, for example the foot holder according to FIG. 1, can be pulled from the zero position with the rope fully wound into a first reversing position when the loading motor is weakly controlled become. The encoder 42 reports this position to the microprocessor and it can then be stored, for example, by pressing the button 25. Then the foot holder can be brought further into the second reversing or stop position and this position can be stored accordingly. The device is now programmed and can be switched on for training. Correspondingly, other types of training can be selected, for example isokinetic training, in which case the speed, the strength and the number of cycles can be selected. As mentioned above, the reversal or stop points can then be set, after which the device is ready for operation.

Es können auch Mittel vorgesehen sein, um Sollwerte, z. B. eine durch längeres Training zu erreichende Kraft, einzugeben und zu speichern und dann jeweils beim Training den erreichten Istwert mit dem Sollwert zu vergleichen und anzuzeigen, welcher prozentuale Teil des Sollwerts erreicht wurde.Means can also be provided to setpoints, e.g. B. enter and save a force to be achieved through longer training and then compare the actual value achieved with the target value during training and display which percentage of the target value has been reached.

Wie erwähnt, übernimmt der Belastungsmotor 5 im wesentlichen die Funktion von Gewichten herkömmlicher Trainingsgeräte. Entsprechend dem diesem Motor zugeführten Strom wirkt auf das Zugseil 8 stets ein bestimmter Zug, der von der trainierenden Person überwunden werden muss. Die oben erwähnten Umkehr- oder Anschlagpositionen werden dabei dadurch simuliert, dass der Motorstrom vorübergehend bedeutend erhöht oder aber herabgesetzt wird. Wenn also beispielsweise der Fusshalter 15 gegen den Zug des Seils 8 in Fig. 1 nach links verschoben wird, wird das Ende dieser Bewegung dadurch bestimmt, dass der Motorstrom und damit der Widerstand erheblich erhöht wird, womit die trainierende Person weiss, dass sie nun den Fusshalter in umgekehrter Richtung, d. h. mit dem Seilzug, bewegen soll. Am anderen Endes des Hubs kann nun der Motorstrom und damit der Seilzug vorübergehend herabgesetzt werden, was die trainierende Person spürt, und was sich automatisch in einer Umkehr der Bewegungsrichtung auswirkt. Es könnte natürlich auch eine rein mechanische Bremse vorgesehen sein, welche jeweils bei Erreichen des Umkehrpunktes wirksam wird und die Bewegung bremst, womit die trainierende Person weiss, dass nun die Bewegungsrichtung umzukehren ist. Die elektrische Bestimmung der Umkehrpunkte hat jedoch den Vorteil, dass keine schlagartigen Verzögerungen auftreten.As mentioned, the load motor 5 essentially takes on the function of weights of conventional training devices. Corresponding to the current supplied to this motor, a certain train always acts on the pull cable 8, which must be overcome by the training person. The above-mentioned reversal or stop positions are simulated by temporarily increasing or decreasing the motor current significantly. If, for example, the foot holder 15 is shifted to the left against the pull of the rope 8 in FIG. 1, the end of this movement is determined by the fact that the motor current and thus the resistance is increased considerably, with which the exercising person knows that he is now the Foot holder in reverse direction, ie with the cable. At the other end of the stroke, the motor current and thus the cable can be temporarily reduced, which the exercising person feels, and which automatically results in a reversal of the direction of movement. Of course, a purely mechanical brake could also be provided, which takes effect when the reversal point is reached and brakes the movement, so that the exercising person knows that the direction of movement must now be reversed. However, the electrical determination of the reversal points has the advantage that there are no sudden delays.

Es sei noch darauf hingewiesen, dass es kaum möglich ist, mit dem Motor 5 zugleich die Geschwindigkeit und die Kraft zu steuern. Beim oben erwähnten isotonischen Training handelt es sich um eine Kraftsteuerung, d. h. der Kraftverlauf in Funktion des Wegs kann gewählt werden, während die Bewegungsgeschwindigkeit von der trainierenden Person bestimmt wird. Umgekehrt wird beim isokinetischen Training die Bewegungsgeschwindigkeit geregelt, während der Benutzer die Kraft beliebig wählen kann.It should also be pointed out that it is hardly possible to control the speed and the force simultaneously with the motor 5. The isotonic training mentioned above is power control, i. H. the force curve as a function of the path can be selected, while the speed of movement is determined by the person exercising. Conversely, the speed of movement is regulated in isokinetic training, while the user can choose the strength as desired.

Es sind verschiedene Ausführungsvarianten möglich. Mit der oben erwähnten Schnittstelle des Bedienungsgerätes könnte anstelle eines PC auch ein Schlüssel verbunden werden, welcher mindestens ein bestimmtes Programm abzuspeichern gestattet. Ein solcher Schlüssel könnte dann einer bestimmten Person zugeordnet werden, welche mit Hilfe dieses Schlüssels jeweils das ihr angepasste Programm eingeben und dann das entsprechende Training durchführen kann. Das beim Ausführungsbeispiel vorgesehene Zugseil bietet gewisse Probleme, weil es nur auf Zug und nicht auf Druck belastet werden kann, und weil Massnahmen zu treffen sind, um stets ein gleichmässiges, geordnetes Aufwickeln des Seils zu gewährleisten. Es könnte daher beispielsweise auch ein direkter Antrieb des Angriffsorgans, also beispielsweise des Fusshalters gemäss Fig. 1, mittels einer Zahnstange und eines Ritzels erfolgen. Eine derartige lineare Antriebseinheit könnte dann als Ausleger ausgebildet sein. Unter Umständen könnte auch ein endloses Seil oder eine endlose Kette vorgesehen sein, womit Kräfte in beiden Richtungen übertragen werden können. Anstelle eines Gleichstrommotors könnte auch ein Asynchronmotor vorgesehen sein. Die Wahl der Geschwindigkeit könnte auch mittels eines Regelelementes automatisch zusammen mit der Tonhöhe gewählt werden. Das Gerät kann auch ohne Ausleger 11 bzw. 34 verwendet werden, indem ein geeignetes Angriffsorgan direkt an dem über die Umlenkrolle 19 geführten Zugseil 8 angebracht ist.Different versions are possible. Instead of a PC, a key could be connected to the above-mentioned interface of the operating device, which key allows at least one specific program to be saved. Such a key could then be assigned to a specific person, who can use this key to enter the program adapted to them and then carry out the corresponding training. The pulling rope provided in the exemplary embodiment offers certain problems because it can only be loaded under tension and not under pressure, and because measures have to be taken in order to always ensure a uniform, orderly winding of the rope. For example, a direct drive of the attack member, that is to say, for example, of the foot holder according to FIG. 1, could therefore also take place by means of a toothed rack and a pinion. Such a linear drive unit could then be designed as a boom. Under certain circumstances, an endless rope or chain could also be provided, with which forces can be transmitted in both directions. Instead of a DC motor, an asynchronous motor could also be provided. The choice of speed could also be selected automatically together with the pitch by means of a control element. The device can also be used without a boom 11 or 34, in that a suitable attack member is attached directly to the pull cable 8 guided over the deflection roller 19.

Das Steuergerät 21 kann auch auf einem Gestell, z. B. auf einem einfachen Rohrgestell, montiert sein. Dabei kann die Frontplatte des Steuergerätes eine geeignete Neigung von beispielsweise 17° aufweisen. Das Gestell kann so gestaltet sein, dass es um 90° aus einer vertikalen in eine horizontale Lage gebracht werden kann, in welcher Lage das Steuergerät durch eine liegende Person beobachtet und bedient werden kann.The control unit 21 can also on a frame, for. B. on a simple tubular frame. The front panel of the control device can have a suitable inclination of, for example, 17 °. The frame can be designed in such a way that it can be moved from a vertical to a horizontal position by 90 °, in which position the control device can be observed and operated by a person lying down.
