Abstract

Die Erfindung betrifft ein Uebungsgeraet zur Entwicklung der Muskeln des Koerpers durch Ueberwinden eines Widerstandes mit einem vom Uebenden gezogenen oder gedrueckten Krafthebel und einem mit einem Gewicht versehenen Lasthebel. Es ist Aufgabe der Erfindung, das Uebungsgeraet so auszubilden, dass die Masse des Gewichts um ein Mehrfaches kleiner ist als die durch den Uebenden aufzubringende Kraft. Erfindungsgemaess wird dies dadurch erreicht, dass am Krafthebel in einem relativ grossen Abstand zu dessen Anlenkpunkt und am Lasthebel in einem relativ kleinen Abstand zu dessen Anlenkpunkt Ausleger fest angeordnet sind, die sich beide in Richtung auf den anderen Hebel zu erstrecken und an ihren freien Enden durch eine Koppel untereinander verbunden sind. Das freie Ende des Krafthebels ist als Teleskopstab ausgebildet und zum Erreichen einer geradlinigen Bewegung in einer Kulisse gefuehrt. Fig. 1The invention relates to a Uebungsgeraet for developing the muscles of the body by overcoming a resistance with a pulled or pressed by Uebenden force lever and a weight bearing load lever. It is an object of the invention to form the exercise device in such a way that the mass of the weight is several times smaller than the force to be applied by the practitioner. According to the invention this is achieved in that the force lever at a relatively large distance to the articulation point and the load lever at a relatively small distance to the articulation point boom are fixedly arranged, both extending in the direction of the other lever and at their free ends a paddock are interconnected. The free end of the power lever is designed as a telescopic rod and guided to achieve a linear movement in a backdrop. Fig. 1

Description

Erfindungsgemäß wird dies dadurch erreicht, daß am Krafthebel in einem relativ großen Abstand zum Anlenkpunkt und am Lasthebel in einem relativ kleinen Abstand zu dessen Anlenkpunkt Ausleger fest angeordnet sind, die sich beide in Richtung auf den anderen Hebel zu erstecken und an ihren freien Enden durch eine Koppel untereinander verbunden sind. Das freie Ende des Krafthebels ist mit einem Ausziehstück versehen und damit als Teleskopstab ausgeführt. Zum Erreichen einer geradlinigen Bewegung ist er in einer Kulisse geführt. An seinem Ende ist über eine Rolle ein Seil befestigt, das zu unterschiedlichen Griffelementen geführt ist, diefür verschiedene Übungen in derfürden Übenden jeweils günstigsten Lage angeordnet sind. Das Gewicht ist auf dem Lastarm verschiebbar angeordnet.According to the invention this is achieved in that the force lever at a relatively large distance to the articulation point and the load lever at a relatively small distance to the articulation point boom are fixed, the both extend in the direction of the other lever and at their free ends by a Coupling are interconnected. The free end of the power lever is provided with a Ausziehstück and thus designed as a telescopic rod. To achieve a linear movement, he is guided in a backdrop. At its end, a rope is attached via a roller, which is guided to different grip elements, which are arranged for different exercises in the most favorable for the practitioner. The weight is slidably mounted on the load arm.

Die Kraft des Übenden wird vom Krafthebel über die Koppel auf den Lasthebel übertragen. Dabei müssen die Ausleger so bemessen sein, daß der Scheitelpunkt eines Dreiecks mit der gedachten Verbindungslinie durch den Anlenkpunkt der Koppel am Ausleger des Kraftarms und den Anlenkpunkt des Kraftarms am Rahmen als Basis und der Koppel als den einen Schenkel und der gedachten Verbindungslinie zwischen dem Anlenkpunkt der Koppel am Ausleger des Lastarms und dem Anlenkpunkt des Kraftarms vom Gestell weg auf das Griffende des Kraftarms zu gerichtet ist.The exerciser's power is transferred from the power lever via the coupling to the load lever. In this case, the boom must be sized so that the vertex of a triangle with the imaginary connecting line through the pivot point of the coupling on the boom of the power arm and the pivot point of the power arm on the frame as a basis and the coupling as the one leg and the imaginary line connecting the pivot point Coupling on the boom of the load arm and the pivot point of the power arm is directed away from the frame to the handle end of the power arm.

Die durch das Gewicht auf dem Lastarm erzeugte Widerstandskraft wird durch das Heb.elsystem so übersetzt, daß der Übende eine um das Mehrfache größere Kraft aufwenden muß. Daraus ergibt sich, daß das Gewicht gegenüber den herkömmlichen Gewichtspaketen klein ist, wodurch die bisher aufgetretenen Geräusche beim Absetzen des Gewichts entfallen. Durch die Unterbringung in einem kastenförmigen Rahmen ist jegliche Unfallgefahr beseitigt. Die Möglichkeit des leichten Verschiebens des Gewichts auf dem Lastarm ergibt eine bequeme Einstellmöglichkeit deraufzuwendenden Kraft, so daß der Übende selbst die Einstellung vornehmen kann.The resistance force generated by the weight on the load arm is translated by the lifting system so that the exerciser must expend a force many times greater. It follows that the weight compared to the conventional weight packages is small, which eliminates the previously occurred noise when discontinuing the weight. By housing in a box-shaped frame any accident risk is eliminated. The possibility of easily shifting the weight on the load arm results in a convenient adjustment of the force to be applied, so that the exerciser himself can make the adjustment.

Field of application of the invention

The invention relates to an exercise device for developing the muscles of the body by overcoming a resistance with a trained by the exerciser or depressed force lever and a weighted load lever, which are designed as · one-armed lever and at least approximately parallel to each other.

Characteristic of the known technical solutions

There are already numerous exercise devices for the development of the muscles are known in which the practitioner lifts and lowers a weight via a lever assembly or cables at regular intervals a weight. The weights are usually made of a variable number of plates or discs, which are combined to form a weight package. The weights are slidably mounted on a lever arm to vary the load of the exerciser can. The mass of the weight usually corresponds approximately to the force to be applied by the exerciser. In many embodiments, the mass of the weight is also greater than the force to be applied due to the fact that the cable guide or a leverage is attached to the bottle. This results in large weight packages.

When wiping caused by sudden shocks that are associated with a lot of noise and contain by the compression of the individual weight plates an accident hazard. In brochures is therefore stated that the installation of the device should be made in rooms with sound insulation and rubber or felt mats are to be placed. Varying the load is associated with inserting or removing the heavy weight plates. Due to the large mass, the devices must be fixed in place and are at least not easily transportable. From US 4357010 an exercise device is known, which consists of a one-armed force lever and a one-armed load lever. At the free end of the power lever, a grip element for the exerciser is attached, at the free end of the load lever, a weight. To adjust the load, the mass of the weight is changeable. Between the bearing of the power lever and the handle for the exerciser a coupling is articulated, which connects the power lever with the load lever. The paddock is adjustable in length to adjust the grip height to the size of the exerciser. Furthermore, the load lever is extended beyond its bearing point and connected by a hydraulic cylinder with an adjustable by-pass as a damping member with the frame. Although this arrangement allows a relatively large adjustability of the load of the practitioner, but the weight here also corresponds to the applied force, so that a large mass is to be attached. To damp the shocks when weaning a shock spring is mounted under the weight. If a reduction of the shocks during weaning is achieved by the hydraulic damping member and the shock spring, the described deficiencies of the known exercise devices are also present here.

Object of the invention

It is an object of the invention to provide a strength training device that operates quietly and accident-proof, has a large adjustment range and is easy to transport. ·

Explanation of the essence of the invention

It is an object of the invention, the strength training device in such a way that by a suitable kinematics, the mass of the weight is smaller by a multiple than the applied by the practitioner force, the load should be adjustable by variable leverage.
