Abstract

An apparatus (1) for training muscles comprises a power arm (2) that can pivot about a pivot pin (5) located on a holding element (6). The first linkage point (7) at which a compression spring element (9) is linked to the power arm (2) can be adjusted along the power arm (2). In order to be able to do so, one end region (8) of the compression spring element (9) has a first joint surface (14), and a series of second joint surfaces (16) which are complementary to the first joint surface (14) is located across an adjustment zone (10) along the power arm (2). The first joint surface (14) can be operatively connected to one of the second joint surfaces (16), and the power arm (2) is pressed by another spring element (18) against the one end region (8) of the compression spring element (9) such that the two operatively connected joint surfaces remain in contact with each other. This makes it easy to adjust the force to be applied to the power arm.

Device for exercising the muscles

The present invention relates to a device for exercising the musculature, comprising a force arm which can be equipped with actuators at one end region and which is pivotable with the other end region about a pivot axis which is arranged on a holding element, on which force 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 power arm, while the other

End region of the compression spring element in a second pivot point on

Holding element is articulated.

Such devices for training the muscles are known in many ways. Thus, for example, US Pat. No. 4,618,140 A shows such a device in which the first articulation point on 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 holes is attached to the power arm, the end of the compression spring element is equipped with a bracket that surrounds the power arm, inserted into this bracket is a pin which is pressed by a spring in the respective hole on the power arm, whereby the end of the Pressure spring element on

Power arm is fixed. To adjust the spring - loaded pin must be pulled out of the hole, the bracket at the end of the

Compression spring element can be moved along the power arm, in the desired position, the pin is in turn pressed into the corresponding hole on the spring training can be continued, the force to be overcome on the power arm depending on the setting is larger or smaller.

In this device, the adjustment of the force that counteracts the operation of the power arm, complicated, in particular, the position of the end portion of the compression spring element on the power arm when adjusting must be precisely adjusted so that the pin can penetrate into the bore.

In particular, there is the risk that the pin is not correctly inserted into the bore, so that during the movement of the power arm an unintentional Moving the articulation point of the compression spring element along the

Low-power can be done, which may be uncomfortable for the person who operates the power arm.

The object of the present invention is thus to provide a device for exercising the muscles, in which the articulation point of the compression spring element along the power arm can be adjusted in a simple manner, and in which it is ensured that the articulation of the compression spring element on the power arm in correctly done. It aims to be a space saving and easy to use device

Training the muscles to be created.

According to the invention, this object is achieved by providing one end region of the compression spring element with a first joint surface having a first curvature and along the force arm via an adjustment region a series of second joint surfaces each having a second curvature complementary thereto is formed to the first curvature, have, so that the one end of the

Compression spring element with the first joint surface with one of the second

Articulated surfaces can be brought into operative connection, and that the force arm can be pressed by a further spring element against the one end region of the compression spring element, such that the two are in operative connection

Articulated surfaces are kept in contact.

This inventive embodiment of the device for exercising the musculature can for adjusting the force, which counteracts the actuation of the force arm, the force arm against the effective force of the further spring element of the articular surface of the end portion of the

Compression spring element can be lifted, the compression spring element can be adjusted, the further spring element pulls the power arm again against the end region of the compression spring element, the first articular surface of the one

End region of the compression spring element comes into engagement with one of the second articular surfaces on the power arm, the adjustment of the force has been achieved in the simplest way. The first joint surface is introduced in each case in each case a second joint surface, a mismanagement is thus preventable. Next, the arrangement of the individual elements and the power arm allows a compact design which also provides scope for an aesthetic design of the device for training the muscles.

Advantageously, the curvature of the first joint surface are concave and the bulges of the second joint surfaces are convex, whereby an optimal operative connection is achieved.

Advantageously, the first joint surface and the second joint surfaces are cylindrical, and are the corresponding

Cylinder axes aligned parallel to the pivot axis, resulting in a simple structure and optimal operation of the adjusting device.

Advantageously, the second articular surfaces are formed by cylindrical pins arranged in series and spaced from each other over the adjustment range on the power arm, and the first articular surface is formed in the base of a yoke mounted on one end portion of the compression spring element. This results in a simple and optimally functioning adjustment range of the device. This will be the first

Articular surface reliably held on the second articular surface.

The cylindrical pins are mounted in two opposite and arranged along the region of the force arm webs, which allows easy production of the adjustment.

Advantageously, the compression spring element is a gas spring, which can be used in a simple manner in the device.

Advantageously, the further spring element is designed as a tension spring, which can be mounted in a simple manner in the device for training the muscles. The compression spring element and the tension spring engage in the same end region on the holding element and thus allow a space-saving design. A further advantageous embodiment of the invention is that the tension spring is an elastic band whose one end region can be fastened to the holding element in the region of the second point of articulation and the other end region is detachably fastened to the force arm. This results in an optimal function, by the possibility of loosening the elastic band of the power arm can be achieved that the power arm can be pivoted away from the compression spring element and with respect to the holding member in an extended position, so when not in use this device can be supplied to save space.

Advantageously, a scale is mounted along the adjustment on the power arm, which, for example, visually detect which force counteracts the operation of the power arm.

The holding element can be attached to a support frame, so that, for example, the orientation of the device and the

Height adjustment can be made in an optimal way.

An embodiment of the invention will be explained in more detail by way of example with reference to the accompanying drawings.

8 shows a view from the front of the device for exercising the musculature according to FIG. 7 with pivoted-in force arm.

As can be seen from FIG. 1, the device 1 for exercising the musculature has a force arm 2. The one end portion 3 of the power arm 2 is formed so that not shown in a known manner

Actuators can be used, whereby the power arm 2 can be actuated by the exercising person in a suitable manner. The other end portion 4 of the power arm 2 is pivotable about a pivot axis 5, which is arranged on a holding element 6. In a first articulation point 7, an end region 8 of a compression spring element 9 is articulated on the force arm 2. This first pivot point 7 and thus the one end 8 of the

Pressure spring element 9 is adjustable along an adjustment 10 on the power arm 2, as will be described in detail later. The other end portion 1 1 of the compression spring element 9 is in a second pivot point 12 on

Holding element 6 articulated. In the embodiment shown here, the compression spring element 9 is formed as a gas pressure spring 13.

To train the muscles of the power arm 2 can be pivoted about the pivot axis 5, the gas pressure spring 13 to the actuating force forms a counterforce and pushes the power arm 2 back to the original position, which is obtained upon reaching the fully extended gas spring 13.

As can be seen from FIG. 2, one end region 8 of the compression spring element 9 has a first joint surface 14 at a first curvature 15 on, while along the force arm 2 on the adjustment 10 a number of second joint surfaces 1 6 are arranged, each with a second curvature 17, which are complementary to the first bulge 15 formed. As will be described later, thereby comes the one end 8 of the

Compression spring element 9 with the first articular surface 14 in operative connection with one of the second articular surfaces 16, the first articular surface 14 and the second articular surface 1 6 are pressed by a further spring element 18 against the one end portion 8 of the compression spring element 9, so that the two operatively connected first articular surface 14 and second articular surface 1 6 are held in contact with each other.

As can be seen from Figure 1, a blocking element 31 may be provided, which has the shape of a hollow cylinder, which is provided over the entire length with a longitudinal slot. As can be seen from Fig. 2, this blocking element 31 on the

Fit gas strut 30 when gas strut 13 is in the fully extended position. In this state, the power arm 2 is blocked, it can not be pivoted. This allows this device to

Exercising the muscles, for example, serve to exercise pull-ups.

As can be seen in particular from FIG. 5, the second articular surfaces 16 are formed by cylindrical pins 19 which are arranged in series and at a distance from one another via the adjustment region 10 on the force arm 2

are arranged.

The first joint surface 14 is formed in the base 20 of a fork 21, which fork 21 is attached to one end portion 8 of the compression spring element 9. By this configuration, the first joint surface 14 is concave, while the second joint surfaces 1 6 are convex. The axes of the cylindrical pins 19 are aligned parallel to the pivot axis 5, about which the force arm 2 with respect to the retaining element 6 is pivotable. As has already been mentioned, the power 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 1 6, which are merely inserted into each other, remain in contact with each other. Through this adjustment range 10, the articulation point 7 can be adjusted with respect to the pivot axis 5. When the power arm 2 is in the position in which the compression spring element 9, which is designed as a gas pressure spring 13, in the fully extended position, the power arm 2 can be further pivoted against the spring force of the further spring element 1 8, the fork 21 with the second joint surface 1 6 extends out of the cylindrical pin 19 and the first joint surface 14, the one end portion 8 of the compression spring element 9 can be moved along with the fork 21 along the row of cylindrical pins 19 and can be pivoted by pivoting the power arm 2 in the retract desired position on the corresponding cylindrical pin 19, which in turn causes the further spring element 18 that the first articular surface 14 and the newly selected second articular surface 1 6 of the corresponding cylindrical pin 19 remain in contact again. This allows you to adjust the distance of the first pivot point 2 of the pivot axis 5 in a simple manner, the force applied to the power arm can thus be adjusted accordingly.

Due to the width of the fork 21 and the distance between the individual cylindrical pins 19 from each other ensures that no malfunction during adjustment can occur, the fork 21 is always with a

cylindrical pin 19 to be engaged, ensuring the safe operation

is guaranteed. Even with incorrect latching jumps the fork 21 of the compression spring element 9 under load automatically to the nearest cylindrical pin 21st

The further spring element 18 is advantageously formed as an elastic band 22, one end portion 23 (Figure 2) in the region of the second pivot point 12 can be secured to the support member 6, while the other end portion 24 can be releasably secured to the power arm 2. For this purpose, at this other end portion 24 on the elastic Band 22, a hook 25 are mounted in one of the force arm

attached pin 26 can be hung.

Figure 3 shows a front view of the inventive device 1, it can be seen the force arm 2, which is held pivotably about the pivot axis 5 in the holding element 6. Also visible is the elastic band 22, with which the power arm 2, as described above, is pressed against the compression spring element 9.

From the sectional view according to Figure 4 can be seen how the fork 21 with a cylindrical pin 19 is pivotally engaged. It can be seen that the cylindrical pins 19 are held in two webs 27 which are arranged on the power arm 2.

From Figure 6, the depressed position of the power arm 2 can be seen, the gas spring 13 is in the retracted state, here it can be seen that the fork 21 is supported in an optimal manner on the corresponding cylindrical pin 19, a slipping of the fork 21 from the cylindrical pin 19 is excluded, the safe operation is guaranteed. As can be seen from this figure 6, it is advantageous if the fork 21 is provided on the outside in each case with a recess 28, whereby space is created for the cylindrical pin which is adjacent to the cylindrical pin 19, with which the fork 21 in Intervention is.

As can be seen in Figures 7 and 8, the power arm 2 can pivot about the pivot axis 5 completely away from the gas spring 13, this is the elastic band 22 is posted from the power arm 2, the power arm 2 can then be pivoted, the fork 21st is extended from the respective cylindrical pin 19, thus the power arm 2 can be brought into a parking position, the gas spring 13 is pivoted against the support member 6, the device 1 can be brought into a space-saving position. The elastic band 22 is then in front of the gas spring 13. The holding element 6 and thus the device 1 for exercising the muscles can also be fixed in a known manner, not shown on a support frame, the support member 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 ground or also with respect to an angular position to this support frame.

As can additionally be seen from FIG. 1, a scale 29 can be attached to a first web 27 of the power arm 2, as a result of which

reproducible setting, for example, the applied force for pivoting the power arm in a simple manner is possible.

With this solution according to the invention, in a device for exercising the musculature, which has an actuatable force arm, the force to be applied to the force arm can be adjusted in a simple manner, so that the force to be applied to the force arm can have different sizes.
