Die vorliegende Erfindung bezieht sich auf eine Einrichtung zum Trainieren der Muskulatur, umfassend einen Kraftarm, welcher am einen Endbereich mit Betätigungselementen ausrüstbar ist und welcher mit dem anderen Endbereich um eine Schwenkachse, die an einem Halteelement angeordnet ist, schwenkbar ist, an welchem Kraftarm der eine Endbereich eines Druckfederelementes in einem ersten Anlenkpunkt angelenkt ist, welcher erste Anlenkpunkt entlang des Kraftarms verstellbar ist, während der andere Endbereich des Druckfederelementes in einem zweiten Anlenkpunkt am Halteelement angelenkt ist.The present invention relates to a device for training the muscles, comprising a power arm which can be equipped with actuating elements at one end region and which can be pivoted with the other end region about a pivot axis which is arranged on a holding element, on which power arm the one End region of a compression spring element is articulated in a first articulation point, which first articulation point is adjustable along the force arm, while the other end region of the compression spring element is articulated in a second articulation point on the holding element.

Derartige Einrichtungen zum Trainieren der Muskulatur sind in vielfältiger Weise bekannt. So zeigt beispielsweise das Dokument US 4 618 140 A eine derartige Einrichtung, bei welcher der erste Anlenkpunkt, an welchem der eine Endbereich des Druckfederelementes am Kraftarm angelenkt ist, entlang des Kraftarmes verstellbar ist. Hierzu ist am Kraftarm eine Reihe von Bohrungen angebracht, der Endbereich des Druckfederelementes ist mit einem Bügel ausgestattet, welcher den Kraftarm umschliesst, in diesen Bügel eingesetzt ist ein Stift, der über eine Feder in die jeweilige Bohrung am Kraftarm eingepresst wird, wodurch der Endbereich des Druckfederelementes am Kraftarm fixiert ist. Zum Verstellen muss der federbelastete Stift aus der Bohrung herausgezogen werden, der Bügel am Endbereich des Druckfederelementes kann entlang des Kraftarmes verschoben werden, in der gewünschten Position wird der Stift wiederum in die entsprechende Bohrung über die Feder eingedrückt, das Trainieren kann weitergeführt werden, wobei die zu überwindende Kraft am Kraftarm je nach Einstellung grösser oder kleiner wird.Such devices for training the muscles are known in many ways. For example, the document shows U.S. 4,618,140 A such a device, in which the first articulation point, at which the one end region of the compression spring element is articulated on the force arm, is adjustable along the force arm. For this purpose, a number of bores are made on the power arm, the end area of the compression spring element is equipped with a bracket which surrounds the power arm, a pin is inserted into this bracket, which is pressed into the respective bore on the power arm via a spring, whereby the end area of the Compression spring element is fixed on the force arm.

Bei dieser Einrichtung ist das Verstellen der Kraft, die der Betätigung des Kraftarms entgegenwirkt, kompliziert, insbesondere muss die Position des Endbereichs des Druckfederelementes am Kraftarm beim Verstellen genau eingestellt werden, damit der Stift in die Bohrung eindringen kann. Insbesondere besteht das Risiko, dass der Stift nicht korrekt in die Bohrung eingeführt ist, sodass während des Bewegens des Kraftarmes ein ungewolltes Verschieben des Anlenkpunktes des Druckfederelementes entlang des Kraftarmes erfolgen kann, was für die Person, welche den Kraftarm betätigt, unangenehm sein kann.In this device, the adjustment of the force that counteracts the actuation of the force arm is complicated; in particular, the position of the end region of the compression spring element on the force arm must be precisely adjusted during adjustment so that the pin can penetrate the bore. In particular, there is the risk that the pin is not correctly inserted into the bore, so that an unintentional displacement of the articulation point of the compression spring element along the force arm occurs while the force arm is being moved can, which can be uncomfortable for the person operating the power arm.

Aus US 5,336,142 ist ein Stepper bekannt, in welchem eine jeweilige Fussfläche gegen die Widerstandskraft eines Hydraulikzylinders bewegbar ist und mittels eines Federelements in seine obere Position gezogen wird, wobei Hydraulikzylinder und Federelement jeweils im gleichen Bereich an einem Halteträger und an der Fussfläche angeordnet sind. Die Einstellung der Widerstandkraft kann über eine verstellbare Rastposition erfolgen, welche das Widerstandselement an der Fussfläche einnimmt.Out U.S. 5,336,142 a stepper is known in which a respective foot surface can be moved against the resistance force of a hydraulic cylinder and is pulled into its upper position by means of a spring element, the hydraulic cylinder and spring element being arranged in the same area on a support bracket and on the foot surface. The resistance force can be set via an adjustable detent position which the resistance element assumes on the foot surface.

Aus US 4,796,881 ist eine Mehrzwecktrainingseinrichtung bekannt, bei welcher an einem bewegbaren Kraftarm mittels eines entlang des Kraftarms verstellbaren Befestigungselements ein erstes und ein zweites Federelement angreifen. Hierbei wird gegen die Widerstandskraft eines der Federelement der Kraftarm bewegt und das zweite Federelement ist vorgesehen, um den Kraftarm in seine Ausgangsposition zu bewegen und die Wirkverbindung zwischen erstem Federelement und Kraftarm aufrechtzuerhalten.Out U.S. 4,796,881 a multi-purpose training device is known in which a first and a second spring element act on a movable force arm by means of a fastening element adjustable along the force arm. Here, the force arm is moved against the resistance force of one of the spring elements and the second spring element is provided in order to move the force arm into its starting position and to maintain the operative connection between the first spring element and the force arm.

Die Aufgabe der vorliegenden Erfindung besteht somit darin, eine Einrichtung zum Trainieren der Muskulatur zur Verfügung zu stellen, bei welcher der Anlenkpunkt des Druckfederelementes entlang dem Kraftarm in einfacher Weise verstellt werden kann, und bei welchem gewährleistet ist, dass das Anlenken des Druckfederelementes am Kraftarm in korrekter Weise erfolgt.

In vorteilhafter Weise sind die zweiten Gelenkflächen durch zylindrische Stifte gebildet, die in Reihe und beabstandet voneinander über den Verstellbereich am Kraftarm angeordnet sind, und ist die erste Gelenkfläche im Grund einer Gabel, die am einen Endbereich des Druckfederelementes angebracht sind, ausgebildet. Dies ergibt eine im Aufbau einfachen und optimal funktionierenden Verstellbereich der Einrichtung.

Wie aus Figur 1 ersichtlich ist, weist die Einrichtung 1 zum Trainieren der Muskulatur einen Kraftarm 2 auf. Der eine Endbereich 3 des Kraftarmes 2 ist so ausgebildet, dass in bekannter Weise nicht dargestellte Betätigungselemente eingesetzt werden können, wodurch der Kraftarm 2 durch die trainierende Person in geeigneter Weise betätigt werden kann. Der andere Endbereich 4 des Kraftarmes 2 ist um eine Schwenkachse 5 schwenkbar, die an einem Halteelement 6 angeordnet ist. In einem ersten Anlenkpunkt 7 ist am Kraftarm 2 der eine Endbereich 8 eines Druckfederelementes 9 angelenkt. Dieser erste Anlenkpunkt 7 und somit der eine Endbereich 8 des Druckfederelementes 9 ist entlang eines Verstellbereichs 10 am Kraftarm 2 verstellbar, wie später noch im Detail beschrieben wird. Der andere Endbereich 11 des Druckfederelementes 9 ist in einem zweiten Anlenkpunkt 12 am Halteelement 6 angelenkt. Im hier dargestellten Ausführungsbeispiel ist das Druckfederelement 9 als Gasdruckfeder 13 ausgebildet.How out Figure 1 As can be seen, the device 1 for training the muscles has a power arm 2. One end region 3 of the power arm 2 is designed in such a way that actuating elements (not shown) can be used in a known manner, whereby the power arm 2 can be operated in a suitable manner by the person exercising. The other end region 4 of the power arm 2 can be pivoted about a pivot axis 5 which is arranged on a holding element 6. At a first articulation point 7, one end region 8 of a compression spring element 9 is articulated on the force arm 2. This first articulation point 7 and thus the one end region 8 of the compression spring element 9 can be adjusted along an adjustment region 10 on the force arm 2, as will be described in detail later. The other end region 11 of the compression spring element 9 is articulated at a second articulation point 12 on the holding element 6. In the exemplary embodiment shown here, the compression spring element 9 is designed as a gas compression spring 13.

Zum Trainieren der Muskulatur kann der Kraftarm 2 um die Schwenkachse 5 verschwenkt werden, wobei die Gasdruckfeder 13 zur Betätigungskraft eine Gegenkraft bildet und den Kraftarm 2 wieder in die ursprüngliche Position zurückdrückt, die bei Erreichen der voll ausgefahrenen Gasdruckfeder 13 erhalten wird.To train the muscles, the power arm 2 can be pivoted about the pivot axis 5, the gas pressure spring 13 forming a counterforce to the actuating force and pushing the power arm 2 back into the original position that is obtained when the fully extended gas pressure spring 13 is reached.

Wie aus Figur 2 ersichtlich ist, weist der eine Endbereich 8 des Druckfederelementes 9 eine erste Gelenkfläche 14 bei einer ersten Wölbung 15 auf, während entlang dem Kraftarm 2 über den Verstellbereich 10 eine Reihe von zweiten Gelenkflächen 16 mit jeweils einer zweiten Wölbung 17 angeordnet sind, welche komplementär zur ersten Wölbung 15 ausgebildet sind. Wie später noch beschrieben wird, kommt dadurch der eine Endbereich 8 des Druckfederelementes 9 mit der ersten Gelenkfläche 14 in Wirkverbindung mit einer der zweiten Gelenkflächen 16, die erste Gelenkfläche 14 und die zweite Gelenkfläche 16 werden über ein weiteres Federelement 18 gegen den einen Endbereich 8 des Druckfederelementes 9 gedrückt, sodass die beiden in Wirkverbindung stehenden erste Gelenkfläche 14 und zweite Gelenkfläche 16 miteinander in Kontakt gehalten werden.How out Figure 2 As can be seen, the one end region 8 of the compression spring element 9 has a first joint surface 14 with a first curvature 15 while a row of second joint surfaces 16, each with a second curvature 17, which are complementary to the first curvature 15, are arranged along the power arm 2 via the adjustment region 10. As will be described later, the one end region 8 of the compression spring element 9 with the first joint surface 14 comes into operative connection with one of the second joint surfaces 16, the first joint surface 14 and the second joint surface 16 are pressed against the one end region 8 of the Compression spring element 9 pressed so that the two operatively connected first joint surface 14 and second joint surface 16 are held in contact with one another.

Wie aus Figur 1 ersichtlich ist, kann ein Blockierelement 31 vorgesehen sein, das die Form eines Hohlzylinders aufweist, der über die ganze Länge mit einem Längsschlitz versehen ist. Wie der Fig. 2 entnommen werden kann, lässt sich dieses Blockierelement 31 auf die Gasdruckfederstange 30 aufsetzen, wenn sich die Gasdruckfeder 13 in der voll ausgefahrenen Position befindet. In diesem Zustand ist der Kraftarm 2 blockiert, er kann nicht verschwenkt werden. Dadurch kann diese Einrichtung zum Trainieren der Muskulatur beispielsweise zur Ausübung von Klimmzügen dienen.How out Figure 1 As can be seen, a blocking element 31 can be provided which has the shape of a hollow cylinder which is provided with a longitudinal slot over the entire length. Again Fig. 2 can be removed, this blocking element 31 can be placed on the gas pressure spring rod 30 when the gas pressure spring 13 is in the fully extended position. In this state, the power arm 2 is blocked, it cannot be pivoted. As a result, this device can be used to train the muscles, for example for doing pull-ups.

Wie insbesondere aus Figur 5 ersichtlich ist, werden die zweiten Gelenkflächen 16 durch zylindrische Stifte 19 gebildet, die in Reihe und beabstandet voneinander über den Verstellbereich 10 am Kraftarm 2 angeordnet sind.Like in particular from Figure 5 As can be seen, the second joint surfaces 16 are formed by cylindrical pins 19 which are arranged in series and at a distance from one another over the adjustment area 10 on the power arm 2.

Die erste Gelenkfläche 14 ist im Grund 20 einer Gabel 21 ausgebildet, welche Gabel 21 am einen Endbereich 8 des Druckfederelementes 9 angebracht ist. Durch diese Ausgestaltung ist die erste Gelenkfläche 14 konkav ausgebildet, während die zweiten Gelenkflächen 16 konvex ausgebildet sind. Die Achsen der zylindrischen Stifte 19 sind parallel zur Schwenkachse 5 ausgerichtet, um welche der Kraftarm 2 bezüglich des Halteelements 6 schwenkbar ist.The first joint surface 14 is formed in the base 20 of a fork 21, which fork 21 is attached to one end region 8 of the compression spring element 9. As a result of this configuration, the first joint surface 14 is concave, while the second joint surfaces 16 are convex. The axes of the cylindrical pins 19 are aligned parallel to the pivot axis 5, about which the power arm 2 can be pivoted with respect to the holding element 6.

Wie bereits erwähnt worden ist, wird der Kraftarm 2 über das weitere Federelement 18 gegen das Druckfederelement 9 gedrückt. Damit wird erreicht, dass die erste Gelenkfläche 14 und die jeweilige zweite Gelenkfläche 16, die lediglich ineinander eingeführt sind, miteinander in Kontakt bleiben. Durch diesen Verstellbereich 10 kann der Anlenkpunkt 7 bezüglich der Schwenkachse 5 verstellt werden. Wenn sich der Kraftarm 2 in der Position befindet, in welcher das Druckfederelement 9, das als Gasdruckfeder 13 ausgebildet ist, in der voll ausgefahrenen Position ist, kann der Kraftarm 2 entgegen der Federkraft des weiteren Federelementes 18 weiter verschwenkt werden, die Gabel 21 mit der zweiten Gelenkfläche 16 fährt aus dem zylindrischen Stift 19 und der ersten Gelenkfläche 14 aus, der eine Endbereich 8 des Druckfederelementes 9 kann zusammen mit der Gabel 21 entlang der Reihe der zylindrischen Stifte 19 verfahren werden und lässt sich durch Zurückschwenken des Kraftarms 2 in der gewünschten Position auf den entsprechenden zylindrischen Stift 19 wieder einfahren, wodurch wiederum das weitere Federelement 18 bewirkt, dass die erste Gelenkfläche 14 und die neu ausgewählte zweite Gelenkfläche 16 des entsprechenden zylindrischen Stiftes 19 wieder in Kontakt bleiben. Dadurch kann man den Abstand des ersten Anlenkpunktes 2 von der Schwenkachse 5 in einfacher Weise verstellen, die aufzubringende Kraft auf den Kraftarm lässt sich somit entsprechend einstellen.As has already been mentioned, the force arm 2 is pressed against the compression spring element 9 via the further spring element 18. This ensures that the first joint surface 14 and the respective second joint surface 16, which are only inserted into one another, remain in contact with one another. The articulation point 7 can be adjusted with respect to the pivot axis 5 through this adjustment range 10. When the force arm 2 is in the position in which the compression spring element 9, which is designed as a gas pressure spring 13, is in the fully extended position, the force arm 2 can be further pivoted against the spring force of the further spring element 18, the fork 21 with the The second joint surface 16 extends out of the cylindrical pin 19 and the first joint surface 14, one end area 8 of the compression spring element 9 can be moved together with the fork 21 along the row of cylindrical pins 19 and can be moved back into the desired position by pivoting the power arm 2 back retract again on the corresponding cylindrical pin 19, whereby the further spring element 18 in turn causes the first joint surface 14 and the newly selected second joint surface 16 of the corresponding cylindrical pin 19 to remain in contact again. As a result, the distance between the first articulation point 2 and the pivot axis 5 can be adjusted in a simple manner, and the force to be applied to the force arm can thus be adjusted accordingly.

Durch die Breite der Gabel 21 und den Abstand der einzelnen zylindrischen Stifte 19 voneinander ist gewährleistet, dass keine Fehlfunktionen beim Verstellen auftreten können, die Gabel 21wird immer mit einem zylindrischen Stift 19 in Eingriff sein, wodurch die sichere Funktion gewährleistet ist. Auch bei nicht korrekter Einrastung springt die Gabel 21 des Druckfederelements 9 unter Last automatisch auf den nächstgelegenen zylindrischen Stift 21.The width of the fork 21 and the distance between the individual cylindrical pins 19 ensure that no malfunctions can occur during adjustment, the fork 21 will always be in engagement with a cylindrical pin 19, which ensures reliable function. Even if it is not correctly engaged, the fork 21 of the compression spring element 9 automatically jumps under load onto the closest cylindrical pin 21.

Das weitere Federelement 18 wird in vorteilhafter Weise als elastisches Band 22 ausgebildet, dessen einer Endbereich 23 (Figur 2) im Bereich des zweiten Anlenkpunktes 12 am Halteelement 6 befestigt werden kann, während der andere Endbereich 24 am Kraftarm 2 lösbar befestigt werden kann. Hierzu kann an diesem anderen Endbereich 24 am elastischen Band 22 ein Haken 25 angebracht werden, der in einem am Kraftarm angebrachten Stift 26 eingehängt werden kann.The further spring element 18 is advantageously designed as an elastic band 22, one end region 23 of which ( Figure 2 ) can be attached to the retaining element 6 in the area of the second articulation point 12, while the other end area 24 can be detachably attached to the power arm 2. For this purpose, at this other end region 24 at the elastic Band 22 a hook 25 can be attached, which can be hung in a pin 26 attached to the power arm.

Figur 3 zeigt eine Ansicht von vorne auf die erfindungsgemässe Einrichtung 1, ersichtlich ist der Kraftarm 2, der um die Schwenkachse 5 schwenkbar im Halteelement 6 gehalten ist. Ebenfalls ersichtlich ist das elastische Band 22, mit welchem der Kraftarm 2, wie vorgängig beschrieben worden ist, gegen das Druckfederelement 9 gedrückt wird. Figure 3 shows a view from the front of the device 1 according to the invention, the power arm 2 can be seen, which is held in the holding element 6 such that it can pivot about the pivot axis 5. Also visible is the elastic band 22 with which the force arm 2 is pressed against the compression spring element 9, as described above.

Aus der Schnittdarstellung gemäss Figur 4 ist ersichtlich, wie die Gabel 21 mit einem zylindrischen Stift 19 gelenkig im Eingriff ist. Hierbei ist ersichtlich, dass die zylindrischen Stifte 19 in zwei Stegen 27 gehalten sind, die am Kraftarm 2 angeordnet sind.From the sectional view according to Figure 4 it can be seen how the fork 21 is hingedly engaged with a cylindrical pin 19. It can be seen here that the cylindrical pins 19 are held in two webs 27 which are arranged on the power arm 2.

Aus Figur 6 ist die gedrückte Position des Kraftarms 2 ersichtlich, die Gasdruckfeder 13 befindet sich im eingefahrenen Zustand, hierbei ist ersichtlich, dass die Gabel 21 sich in optimaler Weise auf den entsprechenden zylindrischen Stift 19 abstützt, ein Wegrutschen der Gabel 21 aus dem zylindrischen Stift 19 ist ausgeschlossen, die sichere Funktionsweise ist gewährleistet. Wie aus dieser Figur 6 ersichtlich ist, ist es vorteilhaft, wenn die Gabel 21 an der Aussenseite jeweils mit einer Einbuchtung 28 ausgestattet ist, wodurch Platz geschaffen wird für den zylindrischen Stift, der zum zylindrischen Stift 19 benachbart ist, mit welchem die Gabel 21 im Eingriff ist.Out Figure 6 the pressed position of the power arm 2 can be seen, the gas pressure spring 13 is in the retracted state, here it can be seen that the fork 21 is optimally supported on the corresponding cylindrical pin 19, the fork 21 from slipping out of the cylindrical pin 19 is excluded , the safe functioning is guaranteed. How out of this Figure 6 As can be seen, it is advantageous if the fork 21 is equipped with an indentation 28 on the outside, whereby space is created for the cylindrical pin which is adjacent to the cylindrical pin 19 with which the fork 21 is in engagement.

Wie den Figuren 7 und 8 entnommen werden kann, lässt sich der Kraftarm 2 um die Schwenkachse 5 vollständig von der Gasdruckfeder 13 wegschwenken, hierzu wird das elastische Band 22 aus dem Kraftarm 2 ausgehängt, der Kraftarm 2 kann dann verchwenkt werden, wobei die Gabel 21 aus dem jeweiligen zylindrischen Stift 19 ausgefahren wird, somit kann der Kraftarm 2 in eine Parkposition gebracht werden, die Gasdruckfeder 13 wird gegen das Halteelement 6 geschwenkt, die Einrichtung 1 kann dadurch in eine platzsparende Position gebracht werden. Das elastische Band 22 befindet sich dann vor der Gasdruckfeder 13 .Like that Figures 7 and 8 can be removed, the power arm 2 can be pivoted completely away from the gas pressure spring 13 about the pivot axis 5, for this purpose the elastic band 22 is detached from the power arm 2, the power arm 2 can then be pivoted, the fork 21 from the respective cylindrical pin 19 is extended, thus the power arm 2 can be brought into a parking position, the gas pressure spring 13 is pivoted against the holding element 6, the device 1 can thereby be brought into a space-saving position. The elastic band 22 is then located in front of the gas pressure spring 13.

Das Halteelement 6 und somit die Einrichtung 1 zum Trainieren der Muskulatur kann ebenfalls im bekannter, nicht dargestellter Weise an einem Traggestell befestigt werden, das Halteelement 6 und somit die Einrichtung 1 zum Trainieren der Muskulatur kann dann bezüglich dieses Traggestells eingestellt werden, beispielsweise hinsichtlich der Höhe über Boden oder auch hinsichtlich einer Winkelposition zu diesem Traggestell.The holding element 6 and thus the device 1 for training the muscles can also be attached to a support frame in a known manner, not shown, the holding element 6 and thus the device 1 for training the muscles can then be adjusted with respect to this support frame, for example in terms of height above the ground or in terms of an angular position to this support frame.

Wie zusätzlich aus Figur 1 ersichtlich ist, kann an einem ersten Steg 27 des Kraftarms 2 eine Skala 29 angebracht sein, wodurch eine reproduzierbare Einstellung beispielsweise der aufzubringenden Kraft zur Verschwenkung des Kraftarms in einfacher Weise möglich wird.How in addition Figure 1 As can be seen, a scale 29 can be attached to a first web 27 of the power arm 2, whereby a reproducible setting, for example, of the force to be applied for pivoting the power arm, is possible in a simple manner.

Mit dieser erfindungsgemässen Lösung kann bei einer Einrichtung zum Trainieren der Muskulatur, die einen zu betätigbaren Kraftarm aufweist, die auf den Kraftarm aufzubringende Kraft in einfacher Weise verstellt werden, sodass die auf den Kraftarm aufzubringende Kraft unterschiedliche Grössen aufweisen kann.With this solution according to the invention, the force to be applied to the force arm can be adjusted in a simple manner in a device for training the musculature which has an actuatable force arm, so that the force to be applied to the force arm can have different magnitudes.
