Description

Die Erfindung betrifft ein Trainingsgerät zur Bewegungstherapie, insbesondere zur Bewegung der Arme oder der Beine von körperbehinderten Personen, mit zwei Handgriffen oder mit zur Aufnahme der Füße eingerichteten Pedalen bzw. Fußschalen, die an einer drehbar gelagerten, zylindrischen Trägerscheibe angeschlossen und ihrerseits um ihre zur Drehachse der Trägerscheibe parallele Trägerwelle drehbar gelagert sind, wobei die Trägerscheibe durch einen umfangsseitig angreifenden Motor drehantreibbar ist.The invention relates to a training device for Movement therapy, especially for the movement of the arms or the legs of disabled people, with two Handles or with the feet set up Pedals or footrests attached to a rotatably mounted cylindrical carrier disc connected and in turn about its parallel to the axis of rotation of the carrier disk Carrier shaft are rotatably supported, the carrier disk by a motor attacking the circumference is driven by rotation.

Derartige Trainingsgeräte sind in vielfältigen Ausführungsformen im Stand der Technik bekannt, wobei ein häufig auftretendes Problem darin besteht, daß der Abstand zwischen den Fußschalen unphysiologisch groß ist. Daher wurde dazu übergegangen, den Motor außerhalb vom Kurbelkreis zu positionieren und die Antriebswelle über Riemen anzutreiben.Such training devices are in diverse Embodiments known in the art, wherein a common problem is that the distance between the foot shells is unphysiologically large. Therefore  was switched to the engine outside of Position crank circuit and drive shaft over Drive belt.

Wesentlich ist bei Körperbehinderten auch, daß der Radius des Kurbelkreises verändert, also individuell angepaßt werden kann. Diese Verstellung ist üblicherweise nur mit Hilfe von Werkzeug möglich und vergrößert darüberhinaus den Abstand zwischen den Fußschalen zusätzlich. Ungeachtet dessen verursachen die hierzu bisher bekannten Lösungen nicht unbeträchtliche Kosten.It is also important for the physically handicapped that the radius of the crank circle changed, so individually adjusted can be. This adjustment is usually only with Tool possible and enlarged the distance between the foot shells additionally. Regardless this causes the previously known solutions for this not inconsiderable costs.

Der Erfindung liegt die Aufgabe zugrunde, ein Trainingsgerät der eingangs genannten Art zu schaffen, bei welchem einerseits der Abstand zwischen den Fußschalen gering gehalten werden kann und bei welchem andererseits eine einfache Verstellung des Kurbelkreises, also der Kurbellänge möglich ist.The invention is based on the object To create training device of the type mentioned, which on the one hand is the distance between the foot shells can be kept low and on the other hand a simple adjustment of the crank circle, so the Crank length is possible.

Diese Aufgabe wird nach der Erfindung dadurch gelöst, daß die Trägerscheibe durch wenigstens drei an ihrem Umfang angreifende Führungselemente gelagert ist, die so angeordnet sind, daß sie die Trägerscheibe um einen Winkel von mehr als 180° umgreifen, und daß in der Trägerscheibe für jedes Pedal mehrere Bohrungen mit unterschiedlichem Abstand von der Drehachse vorgesehen sind, in die der Handgriff bzw. das Pedal mit seiner Trägerwelle lösbar eingesteckt ist.This object is achieved according to the invention in that the carrier disc by at least three on its circumference attacking guide elements is mounted, so are arranged so that they are the carrier disc at an angle of more than 180 °, and that in the carrier disc for each pedal several holes with different ones Distance from the axis of rotation are provided, in which the Handle or the pedal with its carrier shaft releasable is plugged in.

Der durch die Erfindung erreichte Vorteil liegt zunächst darin, daß die Führungselemente für die Trägerscheibe außerhalb des Kurbelkreises angeordnet sind, so daß der gegenseitige Abstand der Fußschalen auf ein Minimum reduziert werden kann. Durch die in der Trägerscheibe vorgesehenen Bohrungen ist in der Art eines Stecksystems eine sehr einfache Verstellung der Kurbellänge möglich, die insbesondere durch den Körperbehinderten selbst ohne die Zuhilfenahme von Werkzeug einfach durchgeführt werden kann. Somit besteht beispielsweise auch die Möglichkeit, im Verlauf eines Trainingsprogramms zunächst mit einer kleinen Kurbellänge zu beginnen und diese stufenweise zu vergrößern.The advantage achieved by the invention lies initially in that the guide elements for the carrier disc are arranged outside the crank circuit, so that the mutual distance of the foot shells to a minimum  can be reduced. Through the in the carrier disc provided holes is in the manner of a plug-in system very simple adjustment of the crank length possible which in particular by the physically handicapped themselves without the use of tools can be carried out easily can. Thus, for example, there is also the possibility in the course of a training program, first with a small crank length to start and gradually enlarge.

In bevorzugter Ausführungsform der Erfindung sind die Führungselemente von mit keilförmigen Laufflächen versehenen Führungsrollen gebildet, die in eine Keilnut an der Mantelfläche der Trägerscheibe greifen. Auf diese Weise ist eine sehr zuverlässige und zugleich leichtgängige Führung der Trägerscheibe gewährleistet.In a preferred embodiment of the invention Guide elements from with wedge-shaped treads provided guide rollers formed in a keyway grab the outer surface of the carrier disc. To this Way is a very reliable and at the same time smooth guidance of the carrier plate guaranteed.

Hierbei besteht insbesondere auch die Möglichkeit, daß unmittelbar eine der Führungsrollen von dem Motor drehangetrieben wird.There is in particular the possibility that immediately one of the guide rollers from the engine is driven.

Weiter ist im Rahmen der Erfindung vorgesehen, daß die Bohrungen für jeden Handgriff bzw. jedes Pedal untereinander gleiche Abstände voneinander aufweisen und geradlinig auf einem gemeinsamen Radius angeordnet sind.It is further provided in the context of the invention that the Holes for every handle or pedal have equal distances from one another and are arranged in a straight line on a common radius.

Die Trägerscheibe ist zweckmäßigerweise von einem kreisbogenförmigen Rahmenteil umgeben, an dem die Führungselemente gelagert sind. Auf diese Weise wird im übrigen eine sehr kompakte Bauform des Trainingsgerätes erreicht. The carrier disc is advantageously from one surrounded by an arcuate frame part on which the Guide elements are stored. In this way remaining a very compact design of the training device reached.  

Um eine einfache Handhabung bei einer Verstellung der Kurbellänge zu gewährleisten, empfiehlt es sich, daß die Trägerwelle etwa mittig einen radial vorstehenden Ringbund als Anschlagelement für die Trägerscheibe aufweist. Beim Versetzen der Trägerwelle von einer Bohrung in eine andere muß diese daher nur gelöst werden und in die neue Bohrung bis zum Anschlag eingesetzt werden.For easy handling when adjusting the To ensure crank length, it is recommended that the Carrier shaft has a radially projecting ring collar approximately in the middle has as a stop element for the carrier disc. At the Moving the carrier shaft from one hole to another therefore it only has to be loosened and into the new hole be used up to the stop.

Im einzelnen kann die Trägerwelle als Hülse ausgebildet sein, in der ein Stellstift axial verstellbar geführt ist, wobei der Stellstift ein Sperrglied betätigt, das radial über die Außenmantelfläche der Hülse vorsteht und die Trägerscheibe auf der dem Anschlagelement abgewandten Seite hintergreift. Zum Lösen der Trägerwelle muß daher nur der Stellstift betätigt werden, der daraufhin das Sperrglied freigibt, so daß die Trägerwelle aus der Bohrung in der Trägerscheibe gelöst werden kann. In besonders einfacher Weise kann hierbei das Sperrglied von einer Kugel gebildet sein und der Stellstift eine Ringnut zur radialen Verstellung der Kugel aufweisen.In particular, the carrier shaft can be designed as a sleeve be in which an adjusting pin is guided axially adjustable, wherein the actuating pin actuates a locking member that is radial protrudes over the outer surface of the sleeve and the Carrier disc on the facing away from the stop element Reaches behind. To release the carrier shaft must therefore only the actuating pin is actuated, which then the Locking member releases, so that the carrier shaft from the Bore in the carrier disc can be solved. In the locking member of be formed a ball and the setting pin an annular groove for radial adjustment of the ball.

Um im übrigen das Trainingsgerät an die individuellen Bedürfnisse des Körperbehinderten anpassen zu können, insbesondere das Gerät auch zum Training der Arme bzw. Füße umrüsten zu können, sieht die Erfindung vor, daß die Handgriffe bzw. die Pedale oder Fußschalen lösbar auf die Trägerwelle aufgesteckt und jeweils durch einen gegen die Kraft einer Feder axial verstellbaren Druckbolzen fixiert sind. Auch hier ist somit ein einfacher Austausch möglich, indem lediglich durch Betätigung des Druckbolzens der Handgriff bzw. das Pedal von der Trägerwelle abgezogen und durch ein entsprechendes anderes Teil ersetzt wird. Hierbei kann der Druckbolzen quer zur Trägerwelle und mit axialem Versatz verlaufen, wobei die Trägerwelle eine der Außenkontur des Druckbolzens angepaßte Ringnut aufweist und der Druckbolzen mit einer den Durchtritt der Trägerwelle ermöglichenden Ringnut versehen ist, wodurch der Handgriff bzw. das Pedal bei entsprechender Stellung des Druckbolzens von der Trägerwelle lösbar ist.To the rest of the training device to the individual Being able to adapt the needs of the disabled especially the device also for training the arms or To be able to convert feet, the invention provides that the Handles or the pedals or footrests releasably on the Carrier shaft plugged on and in each case against the Force axially adjustable pressure pin fixed are. A simple exchange is also possible here, by simply pressing the pushbutton Pulled the handle or the pedal from the carrier shaft and is replaced by a corresponding other part. Here, the pressure pin can be transverse to the carrier shaft and with  axial offset, the carrier shaft one of the Has outer contour of the pressure bolt adapted ring groove and the pressure bolt with the passage of the Carrier shaft enabling annular groove is provided, whereby the handle or the pedal in the appropriate position the pressure pin is detachable from the carrier shaft.

Im folgenden wird die Erfindung an einem in der Zeichnung dargestellten Ausführungsbeispiel näher erläutert; es zeigen:In the following the invention on one in the drawing illustrated embodiment explained in more detail; it demonstrate:

Fig. 6 einen Schnitt längs der Linie A-A nach Fig. 5. Fig. 6 shows a section along the line AA in FIG. 5.

Das in der Zeichnung in Fig. 1 schematisch dargestellte Trainingsgerät dient der Durchführung von Bewegungstherapien, insbesondere zur Bewegung der Arme oder der Beine von körperbehinderten Personen. Dazu kann das Trainingsgerät mit zwei Handgriffen oder mit zur Aufnahme der Füße eingerichteten Pedalen 1 bzw. Fußschalen ausgerüstet sein, die in der Zeichnung jedoch nur angedeutet in den Fig. 5 und 6 wiedergegeben sind. Diese Handgriffe bzw. Pedale 1 sind an einer drehbar gelagerten, zylindrischen Trägerscheibe 2 angeschlossen und ihrerseits um ihre zur Drehachse der Trägerscheibe 2 parallele Trägerwelle 3 drehbar gelagert. Die Trägerscheibe 2 selbst wird durch einen umfangsseitig angreifenden Motor 4 drehangetrieben.The training device shown schematically in the drawing in FIG. 1 is used to carry out movement therapies, in particular for moving the arms or legs of physically disabled people. For this purpose, the training device can be equipped with two handles or with pedals 1 or foot rests which are set up for receiving the feet, but which are only indicated in the drawing in FIGS. 5 and 6. These handles or pedals 1 are connected to a rotatably mounted, cylindrical carrier disc 2 and in turn are rotatably supported about their carrier shaft 3, which is parallel to the axis of rotation of the carrier disc 2 . The carrier disk 2 itself is driven in rotation by a motor 4 which engages on the circumference.

Die Trägerscheibe 2 wird, wie sich insbesondere aus der Fig. 1 ersehen läßt, durch drei an ihrem Umfang angreifende Führungselemente 5 gelagert. Diese Führungselemente 5 sind so angeordnet, daß sie die Trägerscheibe 2 um einen Winkel von mehr als 180° umgreifen, so daß sich die Trägerscheibe 2 nicht selbsttätig lösen kann.As can be seen in particular from FIG. 1, the carrier disk 2 is supported by three guide elements 5 engaging on its circumference. These guide elements 5 are arranged so that they encompass the carrier disc 2 by an angle of more than 180 °, so that the carrier disc 2 cannot come loose automatically.

In der Trägerscheibe 2 sind für jedes Pedal 1 mehrere Bohrungen 6 mit unterschiedlichem Abstand von der Drehachse 7 vorgesehen, in die der Handgriff bzw. das Pedal 1 mit seiner Trägerwelle 3 lösbar eingesteckt ist.In the carrier disk 2 , several bores 6 are provided for each pedal 1 at different distances from the axis of rotation 7 , into which the handle or the pedal 1 with its carrier shaft 3 is detachably inserted.

Die Führungselemente 5 sind, wie dies insbesondere aus der Fig. 2 hervorgeht, von Führungsrollen gebildet, die keilförmige Laufflächen 8 aufweisen und mit diesen in eine Keilnut an der Mantelfläche der Trägerscheibe 2 greifen. In Fig. 2 dient diese dargestellte Führungsrolle zugleich dem Antrieb der Trägerscheibe 2, indem die Führungsrolle selbst von einem Motor 4 drehangetrieben wird.The guide elements 5 , as can be seen in particular from FIG. 2, are formed by guide rollers which have wedge-shaped running surfaces 8 and engage with them in a keyway on the outer surface of the carrier disk 2 . In Fig. 2, this guide roller shown is also used to drive the carrier disc 2 by the guide roller itself is rotated by a motor 4 .

Die Bohrungen 6 für die Handgriffe bzw. die Pedale 1 weisen untereinander gleiche Abstände auf und sind geradlinig auf einem gemeinsamen Radius angeordnet. The holes 6 for the handles or the pedals 1 have the same spacing from one another and are arranged in a straight line on a common radius.

Selbstverständlich besteht auch die Möglichkeit, diese Bohrungen 6 beispielsweise spiralförmig oder in anderer Weise anzuordnen.Of course, there is also the possibility of arranging these bores 6, for example, in a spiral or in some other way.

Wie sich aus der Fig. 1 ergibt, ist die Trägerscheibe 2 von einem kreisbogenförmigen Rahmenteil 9 umgeben, an dem die Führungselemente 5 gelagert sind. Hierdurch ergibt sich eine besonders kompakte Bauform des Trainingsgerätes, das zur Bewegung der Beine vorgesehen ist und daher am oberen Ende des Rahmenteils 9 mit einem Handgriff 10 versehen ist.As can be seen from FIG. 1, the carrier disc 2 is surrounded by an arcuate frame part 9 on which the guide elements 5 are mounted. This results in a particularly compact design of the training device, which is provided for moving the legs and is therefore provided with a handle 10 at the upper end of the frame part 9 .

Wie die Fig. 3 zeigt; weist die Trägerwelle 3 etwa mittig einen radial vorstehenden Ringbund 11 als Anschlagelement für die Trägerscheibe 2 auf. Bei einer Verstellung der Kurbellänge kann daher die Trägerwelle 3 einfach bis zum Anschlag in die Bohrung 6 eingesteckt werden.As Fig. 3 shows; the carrier shaft 3 has a radially projecting annular collar 11 approximately in the middle as a stop element for the carrier disk 2 . When the crank length is adjusted, the carrier shaft 3 can therefore simply be inserted into the bore 6 up to the stop.

Um hierbei außerdem eine Arretierung der Trägerwelle 3 zu gewährleisten, ist diese als Hülse 12 ausgebildet, wobei innerhalb der Hülse 12 ein Stellstift 13 axial verstellbar geführt ist. Der Stellstift 13 betätigt ein Sperrglied 14, das radial über die Außenmantelfläche der Hülse 12 vorsteht und - bei eingesteckter Trägerwelle 3 - die Trägerscheibe 2 auf der dem Ringbund 11 abgewandten Seite hintergreift.Here, in order also to ensure a locking of the support shaft 3, this is designed as a sleeve 12, wherein within the sleeve 12, a regulating pin 13 is guided axially adjustable. The actuating pin 13 actuates a locking member 14 which projects radially beyond the outer circumferential surface of the sleeve 12 and - in an inserted support shaft 3 - the disc substrate 2 on the annular collar 11 engages behind the side facing away.

Im einzelnen ist das Sperrglied 14 von einer Kugel gebildet, wobei der Stellstift 13, wie dies aus Fig. 4 zu ersehen ist, eine Ringnut 15 zur radialen Verstellung der Kugel aufweist. In der in Fig. 4 dargestellten Stellung steht die Kugel radial über die Außenmantelfläche der Hülse 12 hervor, verhindert also ein Lösen der Trägerwelle 3 aus der Trägerscheibe 2. Um die Trägerwelle 3 aus der Trägerscheibe 2 lösen zu können, wird der Stellstift 13 so verschoben, daß die Kugel in die Ringnut 15 eintreten kann.In particular, the locking member 14 is formed by a ball, the adjusting pin 13 , as can be seen from FIG. 4, has an annular groove 15 for the radial adjustment of the ball. In the position shown in FIG. 4, the ball protrudes radially beyond the outer circumferential surface of the sleeve 12 , thus preventing the carrier shaft 3 from being released from the carrier disk 2 . In order to be able to detach the carrier shaft 3 from the carrier disk 2 , the setting pin 13 is displaced so that the ball can enter the annular groove 15 .

In den Fig. 5 und 6 ist dargestellt, wie ein Austausch zwischen den Handgriffen, Pedalen bzw. Fußschalen möglich ist. Diese sind hierzu ebenfalls lösbar auf die Trägerwelle 3 aufgesteckt und werden durch einen Druckbolzen 16 fixiert. Dieser Druckbolzen 16 ist - zum Lösen der Handgriffe bzw. Pedale 1 - gegen die Kraft einer Feder 17 axial verstellbar.In FIGS. 5 and 6 it is shown how an exchange between the handles, pedals or foot shells is possible. For this purpose, these are also releasably attached to the carrier shaft 3 and are fixed by a pressure pin 16 . This pressure pin 16 is - for releasing the handles or pedals 1 - axially adjustable against the force of a spring 17 .

Der Druckbolzen 16 verläuft dazu quer zur Trägerwelle 3 mit geringem axialen Versatz, wobei zunächst die Trägerwelle 3 eine der Außenkontur des Druckbolzens 16 angepaßte Ringnut 18 aufweist, in welche hinein der Druckbolzen 16 vorsteht. Hierdurch ist sichergestellt, daß der Handgriff bzw. das Pedal 1 sich ungehindert auf der Trägerwelle 3 drehen kann, ohne sich in axialer Richtung von der Trägerwelle 3 zu lösen.For this purpose, the pressure pin 16 runs transversely to the carrier shaft 3 with a small axial offset, the carrier shaft 3 first having an annular groove 18 which is adapted to the outer contour of the pressure pin 16 and into which the pressure pin 16 projects. This ensures that the handle or the pedal 1 can rotate freely on the carrier shaft 3 without detaching from the carrier shaft 3 in the axial direction.

Der Druckbolzen 16 ist jedoch ebenfalls mit einer den Durchtritt der Trägerwelle 3 ermöglichenden Ringnut 19 versehen, wie dies aus der Fig. 6 zu ersehen ist. Wird der Druckbolzen 16 gegen die Kraft der Feder 17 soweit verstellt, daß die Ringnut 19 im Druckbolzen 16 den Durchtritt der Trägerwelle 3 ermöglicht, so kann das Pedal 1 bzw. die Fußschale von der Trägerwelle 3 abgezogen und entsprechend ausgetauscht werden.However, the pressure pin 16 is also provided with an annular groove 19 which enables the passage of the carrier shaft 3 , as can be seen from FIG. 6. If the pressure pin 16 is adjusted against the force of the spring 17 to such an extent that the annular groove 19 in the pressure pin 16 enables the support shaft 3 to pass through, the pedal 1 or the foot shell can be removed from the support shaft 3 and exchanged accordingly.
