Description

The invention relates to a view of a training device for the stimulation and training of the musculoskeletal system of a person, comprising a person supporting, pivotable with respect to a rocker stand rocker and a drive assembly with at least one motor and preferably at least one transmission element having gear for pivoting driving the rocker.

Training devices with a pivotable rocker are in various embodiments, for example, from EP 1 683 505 A1 , of the WO 2007/124917 A2 , of the DE 20 2006 012 056 U1 and the EP 0 929 284 B1 known. Such training devices with a pivotable rocker have been found to be superior in terms of training effect against exercise equipment with a vibratory driven vibrating plate,

It has been found desirable to include more torso in stimulation and exercise to avoid additional workouts primarily related to the upper body.

The hitherto unpublished German utility model application DE 20 2007 014 078.9 Therefore proposes for a seesaw of the type mentioned above, to provide a gripping element engageable by the person, which can be supported by the person against the gravitational force and / or via which a connection arrangement in tension, in particular tensile stress, is displaceable.

The connection arrangement can be, for example, a pull rope whose one end is fixedly connected to a stationary holding region on the rocker or with the ground, and at the other end of the gripping element is arranged. Although this arrangement has the result that the exercising person must apply a certain amount of force in order to support the gripping element against the force of gravity or to tension the flexible traction cable, the upper body of the exercising person remains relatively immobile. However, in order to more efficiently stimulate the upper body, it is preferable for the exercising person to move more with their upper body.

The DE 20 2007 014 078.9 also provides, the connection assembly, ie, for example, the pull rope, zuzuzukopeln with the rocker. Thus, the forcing given by the engine to the rocker are transmitted via the connection arrangement to the gripping element. The upper body of the exercising person is thus more stimulated than in the case mentioned above, in which the connection arrangement is not motion-coupled with the rocker.

However, a disadvantage here is that the issued the gripping element Movement stroke has only a very small amplitude, which corresponds to a maximum of a stroke amplitude of the outer end of the rocker. The training effect for the upper body is therefore very limited.

It should also be noted that the movement frequency of the gripping element depends on the excitation frequency of the rocker and can not be chosen independently of it. In general, therefore, the gripping element makes exactly opposite or exactly mitläufige pivoting movements to the movement of the rocker. However, in view of more variable training options, greater variability may be desirable here.

The disclosure of the DE 20 2007 014 078.9 and the disclosure of the PCT application claiming priority to this utility model application PCT / EP2008 / 004317 is incorporated by reference into the disclosure of the present application.

A training device of the type mentioned above with respect to a rocker stand pivotal rocker is also off US 2007/0100260 A1 known. evidenced Fig. 5c The rocker can be equipped with ropes so that the user standing on the seesaw can more easily balance the situation.

From the US 2004/0067833 A1 It is known to equip various training devices with a vibration drive. Fig. 7 shows a "cross-country ski trainer" training device in the base of a linear vibration drive should be installed to vibrate the foot plates of the skis. To Fig. 7 The training device is also designed with a Zugseilvorrichtung on a kind of support gallows, which can be equipped with a rotary vibration drive. It is also proposed to integrate a rotary vibration drive in the ski movement mechanism.

Out EP 1 555 066 A1 is a training device with a base vibratable vibration plate is known in which at least one, for example, two bands are connected to the vibration plate and guided over a (respective) arranged on a handle deflection roller.

DE 103 47 542 A1 discloses an exercise device with a hydraulic cylinder-piston device serving as a kind of brake for a pull cable arrangement.

In another aspect, the invention relates to a training device according to the preamble of claim 1, as it is known from US 2006/0046911 A1 is known.

The known exercise device has a base on which the user stands and through which a tension between two handles by the user is guided, so that the user can alternately pull on one or the other end of the rope by means of the respective handle and by means of the other handle can exert a resistance to the Zugseilbewegung. Another embodiment operates with two separate ropes, but which are coupled to each other via a winding spool gear arrangement with each other.

It is therefore an object of the invention to include in the training with the training device, the upper body much stronger and therefore more efficient and to allow a total of the exercising person more variability in their training methods.

To achieve this object, a training device with the features of claim 1 is provided.

Due to the inventive design of the training device with the two gripping elements on the two Zugelementabschnitten it is possible to perform the training effect due to the pivotal movement of the rocker supporting and extending to other body parts arm movements during training with the exercise equipment, for example, similar arm movements during Nordic walking or training with a so-called cross or elliptical trainer and are preferably carried out against by muscular force to be overcome significant counter-forces. It may also be arm movements, such as those that occur or can occur during exercises with so-called Thera bands.

Gripping element according to the invention may also be a free Zugelementende. Above all, however, it is thought that a special handle, ergonomic as possible, a short gripping bar or the like is provided, in each case separately for both Zugelementabschnitte. However, it should not be ruled out that acts as a gripping element in the aforementioned sense, a gripping portion of a continuous, attached to both tension elements gripping bar, the two Zugelementabschnitte so far a common gripping element, namely the continuous gripping bar has. The above-mentioned arm movements usually larger amplitude of motion will usually require separate gripping elements for the two Zugelementabschnitte.

It should be noted that the counteractivity of the arm movements can be enforced by technical means of the training device or can be made possible only by technical means of the training device, so that other, non-opposing arm movements would be possible. However, the latter is generally less preferred in terms of physiological training, so that consideration is given in particular to opposing arm movements, which are preferably enforced by appropriate design of the training device.

In any case, if the exercising person prefers this, he has the freedom to be able to determine himself the frequency with which he alternately pulls on the gripping elements. Also, it can determine the stroke amplitude of the gripping elements, at least within certain limits, depending on how far it pulls alternately on the gripping elements. Thus, the exercising person receives an independent of the clock frequency and lifting height of the rocker possibility to train their upper body at the same time Beinbein.

According to the invention, it is provided that the at least one tension element can be coupled or coupled to the rocker in such a way that the pivoting movement of the rocker moves on the first and the second tension element section in the sense of an alternating shortening and lengthening of the tension element sections, in particular extension under the effect of a force exerted by the person on the respective gripping element tensile force, which are superimposed on the arm movements based on opposing shortenings and extensions. The movement impulses or the resulting alternating, such as impulsive or vibration-like shortenings and extensions of the tension element sections can be the opposing movement strokes as a result of the pivoting movement of the rocker according to a previously discussed embodiment of the training device according to the invention.

It is mainly thought that the training device is designed so that based on the arm movements opposing shortening and extensions of Zugelementabschnitte are much larger than shortenings and extensions of Zugelementabschnitte, which occur due to the induced by the pivotal movement of the rocker motion pulses.

Preferably, the movement impulses act in the sense of an alternating opposite shortening and lengthening of the tension element sections. It is therefore proposed that the pivotal movement of the rocker on the first and the second Zugelementabschnitt acting movement impulses in the sense of an alternating opposite shortening and extension of Zugelementabschnitte, in particular elongation under the action of a force exerted by the person on the respective gripping element tensile force induces.

It may be expedient to provide that the first and the second Zugelementabschnitt belong to separate tension members.

It is generally proposed that the first tension element section and the second tension element section or the separate tension elements by means of a mechanical or / and hydraulic and / or pneumatic coupling arrangement such motion-coupled or bewegungsverkoppelbar that an extension of the one Zugelementabschnitts is necessarily accompanied by a corresponding shortening of the other Zugelementabschnitts.

A particularly expedient and mechanically simple embodiment of the training device is characterized in that the first and the second Zugelementabschnitt belong to a common continuous tension element, which is guided over at least one deflection or guide arrangement of the training device, so that an extension of a Zugelementabschnitts mandatory accompanied by a corresponding shortening of the other Zugelementabschnitts. The deflection or guide arrangement can be regarded as a mechanical coupling arrangement in the sense of the above-mentioned embodiment.

If it is envisaged that at least one deflecting or guiding element of the deflecting or guiding arrangement is adjustable relative to other deflecting or guiding elements, a simple adjustability of the lengths of the two tensioning element sections can be made possible.

In a further development, it is proposed that a middle tensioning element section connecting the two tensioning element sections is guided via at least one deflecting or guiding element of the deflection or guide arrangement assigned to it.

A common adjustability of the mean lengths of the two Zugelementabschnitte can be realized by means of an adjustability of the deflection or guide element, over which the middle Zugelemehntabschnitt runs.

For motion coupling with the rocker or for imparting the motion impulse through the rocker can advantageously be provided a simple mechanical interaction between the rocker and the at least one tension element. For example, it is contemplated that the traction element or the respective traction element is guided via at least one deflecting or guiding element of the training device arranged on the rocker, making use of the rocking motion, in order to couple the gripper elements to the rocker or / and to induce the movement impulses in the sense of an alternating shortening and lengthening of the tension element sections on the basis of the rocking movement or vibration movement. It is not mandatory, but advantageous if in each case at least one deflection or guide element is arranged on the rocker or the vibration plate in association with each of the two Zugelementabschnitte.

A particularly advantageous embodiment of the training device is specified in claim 10.

It has been briefly mentioned the possibility that the first and second Zugelementabschnitt belong to a common continuous tension element. In this case, in the case of the corresponding embodiment mentioned in claim 10, an interaction of the middle tension element section with the deflection or guide element associated therewith can generate the counterforce.

In this context, it is thought that the reaction force is based on friction between a deflection or guide surface of the deflection or guide element and the middle Zuglementabschnitt and / or on a force acting on a deflection roller of the deflection or guide element braking force.

In general, in the case of a mechanical, hydraulic or pneumatic coupling arrangement, the opposing force can be provided by the mechanical or hydraulic or pneumatic coupling arrangement itself, this preferably having mechanical, hydraulic or pneumatic means for adjusting the counterforce.

In the event that the first and the second Zugelementabschnitt belong to the common continuous tension element, it is specifically proposed that the counterforce is at least so large that induced by the thrust movement of the rocker motion pulses cause shortening and extensions of Zugelementabschnitte, without opposing arm movements can not be compensated by changes in Zugelementlage in at least one deflection or guide arrangement.

Appropriately, one can provide that a respective average length for the first and the second Zugelementabschnitt is adjustable, preferably together imperative for both Zugelementabschnitte, or / and that the total length of the first and the second Zugelementabschnitts is adjustable. For example, a manual or electromotive adjustment of at least one tension element articulation point or tension element deflection or guide element may be provided to give this setting possibility. It is generally thought that the mentioned mechanical and / or hydraulic coupling arrangement is designed to adjust the average lengths of the Zugelementabschnitte.

In the event that the first Zugelementabschnitt and the second Zugelementabschnitt or the separate tension elements are coupled by means of a hydraulic coupling arrangement with each other, it is very advantageous if a hydraulic line comprises an adjustable throttle valve, for adjusting a hydraulic resistance, a shortening of the respective Zugelementabschnitts counteracts. The exercising person can adjust the force required by the variable throttle valve to move the respective tension member section. It can be provided that the throttle valve is infinitely adjustable or the adjustment can be made only in certain stages. In principle, when the throttle valve is fully open, a very smooth operation of the tension elements is possible. On the other hand Pulling on the corresponding Zugelementabschnitt is heavier, the further the throttle valve is closed.

The following further training proposals relate to a hydraulic coupling arrangement of the motion-coupled tension elements, unless expressly stated or implied by the respective information.

Advantageously, it can be provided that the hydraulic coupling arrangement comprises at least one hydraulic transmission, which has a first input and output side associated with the first Zugelementabschnitt and a second Zugelementabschnitt associated second input and output side. The input and output sides can be rotating or linearly moving input and output sides.

According to a preferred embodiment, it is provided that the hydraulic coupling arrangement comprises at least two hydraulically coupled hydraulic cylinders, at least one of which is assigned to the first Zugelementabschnitt and at least one second Zugelementabschnitt, and alternately as directly or indirectly by a Zugelementabschnitt acted upon by an actuating force hydraulic Serving cylinder and serve as the other Zugelementabschnitt directly or indirectly with a counter-force acting hydraulic slave cylinder.

Experiments have shown that training of the upper body can be carried out particularly effectively when the hydraulic cylinders, the Zugelementabschnitten for shortening or extension a maximum movement stroke between about 200 mm and about 600 mm, preferably between about 300 mm and 500 mm, most preferably about 400 mm.

In a further development, it is proposed that the first hydraulic cylinder associated with the first tensioning element section and that of the second Zugelementabschnitt associated second hydraulic cylinder each having a cylinder space which is divided by a linearly movable piston into two cylinder compartments, and that the two hydraulic cylinders are interconnected by two hydraulic lines, such that both cylinder compartments of the respective cylinder chamber hydraulically connected respectively with associated cylinder compartments of the other hydraulic cylinder are. By the two hydraulic cylinders are interconnected by means of two hydraulic lines, the force is safely transmitted once by positive pressure and once by negative pressure, from one to the other hydraulic cylinder.

It lends itself to provide at least one hydraulic connection between two separate by a piston or the already mentioned two Zylinderteilräumen one of the two hydraulic cylinders, by means of an average length of the respective Zugelementabschnitts by setting a piston of the middle length corresponding piston position is adjustable. By means of such a hydraulic connection and the maximum stroke of the hydraulic cylinder can be adjusted.

Advantageously, a hydraulic pump can be provided in the hydraulic connection, by means of which hydraulic medium between the two cylinder part spaces of one of the two hydraulic cylinders can be transferred. The hydraulic pump may be, for example, a manually operable hydraulic pump. During normal operation of the training device, the hydraulic pump is not actuated, which prevents hydraulic fluid from being transferred between the two cylinder compartments of one of the two hydraulic cylinders.

shows gripping elements to which once from above ( Fig. 9a ) and once from below ( Fig. 9b ) Zugelementabschnitte are guided.

This in Fig. 1 shown exercise equipment is composed of a housing serving as a rocker stand with a base plate 1 arranged in the lower region, to which a vertical front wall, a vertical rear wall and vertical side walls 21 and 22 are fixed such that the housing forms an open-topped box as a whole ,

On the base plate 1 designed as an electric motor 2 drive by means of several fasteners 3 is anchored. The output shaft of the electric motor 2 carries a pulley 4. Parallel to the output shaft of the electric motor 2 is spaced from this one axis 6 mounted on two bearings. On the axis 6 is aligned with the pulley 4 another, not shown here, pulley attached. About the pulleys 4 and and the other pulley runs a belt 5, which is preferably designed as a toothed belt, but can also be formed by a V-belt or a flat belt. Alternatively, a drive by means of a chain, a rope, a gear transmission, a bevel gear or the like is possible, wherein in a bevel gear, the output shaft of the electric motor 2 is arranged perpendicular to the axis 6.

The mentioned, opposite end portions of the axis 6 associated bearings are also mounted by means of fasteners 10 on the base plate 1. In the area of the bearing 6 two eccentric discs are attached to the axis. At the eccentric discs an eccentric pin 13 is arranged in each case parallel to the axis 6 in alignment with one another. At the eccentric pin 13, the lower end of each rocker arm 14 is rotatably mounted. The upper ends of the two rocker arms 14 are connected by means of a respective leaf spring element 50 with the rocker 16. The leaf spring elements 50 are firmly clamped both on the respective rocker arm 14 and on the underside of the rocker 16. Now, if the oscillating lever 14 are moved in an up / down movement by the rotation of the eccentric discs, the leaf spring elements 50 transmit the driving forces to the rocker 16, so that it is pivoted about the rocker axis 23. In this case, the leaf spring element dampens due to its elastic deflection, especially in the dead centers of the eccentric motion occurring shocks, so that they are not transmitted directly and undamped to the rocker and thus the person standing thereon. Of course, the leaf spring elements 50 are dimensioned such that they can safely transmit the acting driving forces on the rocker 16, so that the training device can be operated reliably.

In this exemplary embodiment, a drive arrangement, starting from the electric motor 2, has a force transmission chain which is formed by the belt pulley 4, the belt 5, the further belt pulley, the axle 6, the two eccentrics, the rocking levers 14 designed as push rods and the leaf spring elements 50. The power transmission is split in parallel to the axis 6 on the two eccentrics and the two rocker arms 14. The only force transmission chain in the exemplary embodiment has gear elements arranged parallel to one another here, which execute the same movements during operation and which belong to the same drive arrangement in the exemplary embodiment.

The rocker 16 is supported in this embodiment in its center on its underside by means of a rocker shaft 30 defining the rocker axis 23, which is mounted in a respective bearing 17 mounted on the front wall and on the rear wall of the housing by means of fasteners 18. The rocker 16 has a total length L of about 70 centimeters. The length L is slightly less than the distance of the side walls 21 and 22, so that the rocker 16 is arranged almost flush with the upper edge of the housing, but so much play on the side walls 21 and 22 and the front wall and the rear wall that she can perform an oscillating oscillating or pivoting movement about her rocker axis 23. However, the gap between the side edges of the rocker 16 and the walls is kept so small that no body parts or objects are pinched can.

The amplitude of the oscillating oscillating movement of the rocker 16 depends on the size of the distance of the eccentric pin 13 to the center of the axis 6. It also depends on the length of the rocker arm 14 and of the Positivon a connection 15 of the rocker arm on the rocker. Preferably, the amplitude is variable in the range of 1 mm to about 40 mm. Such variability of the amplitude can be achieved, for example, by a set of exchangeable eccentric discs whose eccentric pins have different distances from the rotary shaft 6. Furthermore, it can be thought in unchanged use coming eccentrics, the connection 15 in the direction orthogonal to the rocker axis slidably attach to the rocker. Such a releasable attachment could be achieved, for example, by engageable complementary profiles, for example in the sense of detents or the like, to the connections and the rocker. Here, the profiles for secure fixing of the connections during operation could additionally be pressed against each other by a screw or the like and clamped: Finally, it is also thought that the rocker arms 14 are designed such that they are adjustable in length to a medium Adjust horizontal or tilt of the rocker. Of course, combinations of said adjustment options on the various transmission elements are possible for setting the amplitude as needed. The adjustment of such adjustment can be done manually or automatically, for example, using appropriate actuators.

Of course, the user can also influence the amplitude by placing his feet more or less far to the right and left of the rocker axis 23 on the rocker 16.

An adjustment of the swing amplitude regardless of the mentioned change in the foot position on the rocker has the advantage that the training effect can be increased at a constant, in particular ideal or comfortable for the person foot distance. Furthermore, can be avoided by an independent of the foot position amplitude adjustment on the rocker, which occur especially when a person transmits its weight through a very wide foot position completely outside on the rocker.

Furthermore, preferably, the rotational speed of the electric motor 2 is variable, so that it is possible to set a range of about 3 to 70 Hz for the frequency of the oscillating movement of the rocker 16. The speed change of the electric motor 2 is preferably carried out by a frequency converter.

The training device is further preferably with a in Fig. 1 indicated control unit 24 equipped with a program memory 25, in which several different training programs with a respective different temporal course of the frequency and / or the amplitude of the oscillating oscillatory movement of the rocker 16 are stored and retrievable as needed. By means of such a control device and the above-mentioned actuators of the adjusting elements for amplitude variation could be controlled.

However, the user can also manually set the frequency and / or the amplitude in the variant equipped with a program memory 25 as well as in a simpler variant. The adjustment of the parameters is preferably carried out on a hand strap, not shown, known per se, for example, which is attached to the front wall and extends approximately at chest height of the user. However, it can also be done spielsweise by rotary switches on a side wall 22 of the housing.

In the Fig. 2 a second embodiment of the exercise device is shown, which differs from the first embodiment in that the rocker 16 by means of at least one further leaf spring element 54 elastically on a on the housing of the training device, in particular the front and Rear wall or a different stand assembly, mounted carrier 56 is held. The carrier 56 is attached to the front wall and the rear wall and extends over the entire width of the housing. At the top of the carrier 56, the blade member 54 is positively clamped and preferably matenialschlüssig. An upwardly facing end of the leaf spring element 54 is clamped in the rocker 16. Between these two Einspannungsbereiche the leaf spring element 54 is free and may be based on the Fig. 2 bend to the left and to the right, so that a pivoting of the rocker 16 due to the transmitted by the rocker arm 14 on the rocker 16 driving force can be done. In this case, no fixed pivot axis is determined in such a holder of the rocker 16, as in a pivot bearing according to the embodiment of Fig. 1 the case is because the amount of bending and the exact course of deflection of the leaf spring element 54 are influenced by various factors, such as the weight of the person standing on the rocker, the person's foot position, rocker frequency and lifting height. In such an embodiment, the rocker also experiences no pure rotational movement about a pivot axis, but moves translationally to some extent along an arcuate portion corresponding to the spatially distributed between the carrier and rocker deflection of the leaf spring member 54 to the left and to the right.

Advantageously, by means of the elastic support of the rocker 16, it can be achieved that the latter performs a translational movement superimposed on the actual pivoting movement, such that a reference point at a rocker end follows a corresponding path of movement corresponding to a lying eight.

It should be noted that instead of extending in the cross-section in the vertical direction leaf spring elements also in cross-section extending in the horizontal direction leaf spring elements can be conveniently provided, especially in order to achieve a cushioning in the vertical direction particularly effective. The same applies to the elastic connection of Swing lever on the rocker to cushion the upper and lower reversal point (dead center).

Other possible embodiments can be found in the publications mentioned in the introduction-refer. The above Fig. 1 and 2 based on the Fig. 1 and 5 the publication WO 2007/124917 A2 Thus, for further details of the two embodiments discussed reference is made to the contents of this publication.

In the following, embodiments of training devices according to the invention are explained with a pivotable rocker having two gripping elements on a respective Zugelementabschnitt which by gewillkürte arm movements alternately, in particular in opposite directions, extendable and shortened to assist the training with the exercise equipment and in particular to other body parts, especially the upper arm and the arm muscles, to expand. For example, arm movements can be performed as in Nordic walking or exercising with a so-called cross or elliptical trainer. Advantageously, a coupling device which couples the movement of the tension element sections and possibly also couples with the rocking movement of the rocker, for example a hydraulic, pneumatic or mechanical coupling device, can be provided, for example in the housing of the training device.

To such an equipment of the training device with at least one tension element or at least two Zugelementabschnitten and the training options achieved thereby is supplemented to the DE 20 2007 014 078.9 and the content of the DE 20 2007 014 078.9 enthaftende PCT / EP2008 / 004317 directed.

Fig. 3 represents a first embodiment of the exercise device according to the invention, the figure again serving as a rocker stand Housing with the base plate 1 arranged in the lower region, on which the vertical front wall, the vertical rear wall and the vertical side walls 21 and 22 are attached, shows. The previously described and in the Fig. 1 and 2 shown drive arrangements and rocker bearings are in Fig. 3 not shown for reasons of clarity. A continuous tension element in the form of a pull cable 102, at the ends in each case one in Fig. 3 not shown gripping element is arranged in the form of a handle, is guided in a central portion via a on the rocker 16 or - preferably - the rocker housing arranged pulley 300, extends from this over a pulley 302a and 302b on a respective rocker arms and is deflected from here to a stationary guide roller 106a and 106b. The stationary deflection roller 106a or 106b is fixedly attached to the bottom plate 1 of the housing serving as a rocker stand. At the guide roller 106a and 106b, the pull cable 102 is deflected again to be guided outside the housing either directly or by means of further deflections to the respective handle.

The deflection rollers 302a and 302b can alternatively be positionable at different positions along the respective rocker arm, in order to impart different amplitude to the cable sections extending from there in the direction of the respective grip or to the gripper rod, as indicated by the rocking motion.

The deflection of the continuous cable 102 by the deflection roller 300 is such that the movement strokes exerted on the cable sections do not simply cancel each other out. For this purpose, it is provided that the relative change in position of the cable 102 to the roller is possible only against counteracting opposing forces or braking forces. For this purpose, it may be provided that the cable 102 is wound with several turns around an outer circumference of the roller, so that significant frictional forces occur, which counteract an adjustment of the rope layer relative to the roller. The friction forces can be so great that such an adjustment in fixed role is not possible. The roller 300 may, however, be rotatable against braking forces applied by a braking device in such a manner that on the one hand the rocker movement exerts movement impulses on the two cable sections (insofar as a training effect is achieved as in the aforementioned embodiments discussed above) and on the other hand by counter-rotating arm movements the cable section is lengthened with appropriate shortening of the other cable section and vice versa. In contrast to the movement impulses induced by the rocking motion, counter-rotating movements of the cable sections or handles of greater amplitude of movement are possible. These opposing movements of greater amplitude, which are gewillkürt by appropriate arm movements of the exercising person through appropriate muscle work, and the movement pulses induced by the rocking motion are superimposed on each other. It is an excellent training effect achieved. For example, arm movements such as jogging, Nordic walking, exercising with a pendulum handles having cross-trainer or elliptical trainer and the like are possible, to name just a few examples.

Instead of a rotatable roller, the role may be performed stationary, so not rotatable. In such a case, one may perhaps also better speak of a stationary deflection spindle or a deflection pin or, in general, a deflection surface. In order to achieve the counterforce or braking effect with respect to the middle cable section, the cable can be guided with a desired number of wraps around the guide surface of this component, and due to the gewillkürten arm movements, which is alternately pulled at the left and right end of the rope running the one rope section from the surface with simultaneous emergence of the other cable section on the surface. The traction cable 102 thus moves with its winding relative to the surface, so that friction occurs and, accordingly, a counteracting the relative movement counterforce.

Fig. 4 shows an example of how the pull cable 102 outside the serving as a rocker stand housing can be guided to a gripping member 100a. The pull cable 102 exits the housing through an opening in a front wall 20 opposite a rear wall 19 in order to be guided vertically upwards in the case of a deflection 106 fixedly mounted on a base plate 34. In the side view of Fig. 4 only one Zugseilabschnitt 102a is shown, which leads to the gripping member 100a. The traction cable section 102b, not shown, at the end of which the gripper element 100b, also not shown, is disposed, is located behind the traction cable section 102a or behind the gripping element 100a.

Fig. 5 shows a second embodiment of the exercise device according to the invention, in which the two Zugseilabschnitte are not mechanically coupled to each other via a hydraulic coupling arrangement with each other. For this purpose, in each case a hydraulic cylinder 400a, 400b is firmly attached to the vertical side walls 21, 22 of the housing serving as a rocker stand. Pistons 414a, 414b divide the spaces of the two hydraulic cylinders 400a, 400b into a first cylinder part space 402a, 402b and a second cylinder part space 404a, 404b, respectively. A first hydraulic line 406 connects the first cylinder part spaces 402a, 402b of the two hydraulic cylinders 400a, 400b, and a second hydraulic line 408 connects the second cylinder part spaces 404a, 404b of the two hydraulic cylinders 400a, 400b. Preferably, in one of the two hydraulic lines 406, 408, a throttle valve 410 is provided, as here in the first hydraulic line 406 of the case. Furthermore, as in the exemplary embodiment, the two hydraulic lines 406, 408 can be connected to one another by means of a connection line 412 which can be blocked against flow, wherein a manual hydraulic pump 414 can be expediently arranged in the connecting line 412.

The pistons 414a, 414b of the two hydraulic cylinders 300a, 300b are adjoined in each case by a rod 414a, 414b, which projects out of the respective second cylinder subspace 404a, 404b. Where outside the Hydraulic cylinders 400a, 400b located distal ends of the rods 414a, 414b are pulleys 418a, 418b arranged.

The two deflection rollers 418a, 418b serve to deflect respectively one tension element section 420a, 420b, as shown in FIG Fig. 6 is illustrated. If the exercising person now pulls on the tension element section 420a, which is deflected by the deflection roller 418a, this pulling force causes the piston 414a to be moved in such a way that the second cylinder part space 404a decreases, whereas the first cylinder part space 402a increases. This displacement can take place at most until the piston 414a has reached the end of the cylinder 300a. In this displacement, hydraulic medium is displaced from the second cylinder part space 404a and passes via the second hydraulic line 408 to the second cylinder part space 404b of the other hydraulic cylinder 400b. This causes the piston 414b of the hydraulic cylinder 400b to be displaced toward the first cylinder subspace 402b. In this case, hydraulic medium is displaced in an analogous manner from the first cylinder part space 402b and passes via the first hydraulic line 406 to the first cylinder part space 402a of the hydraulic cylinder 300a. There is thus a closed hydraulic circuit. If the exercising person subsequently pulls on the other gripping element, the above-described movements run off in the opposite direction.

As can be clearly seen, this arrangement causes pulling on the tension member portion 420a to result in an opposite displacement of the piston 414b which is connected to the deflection roller 418b via the rod 414b, which in turn transfers to the corresponding other tension member portion 420b transfers. Thus, the two Zugelementabschnitte 420a, 420b on the in Fig. 5 shown hydraulic arrangement with each other motion coupled.

The throttle valve 410 provided in the first hydraulic line 306 serves thereby to be able to vary the flow resistance between the two hydraulic cylinders 400a, 400b. It can be provided for this purpose a continuously variable throttle valve or even an adjustable only in stages throttle valve. The exercising person can thus easily adapt the degree of difficulty of his exercises to his wishes by means of the throttle valve 410.

In addition, the first and second hydraulic lines 406, 408 are connected to each other by means of the connection line 412 in which a manual hydraulic pump 414 is disposed. During normal training operation, the hydraulic pump 414 is inactive, preventing hydraulic fluid from passing from one of the hydraulic lines 406, 408 to the other hydraulic line 408, 406. Actuation of the hydraulic pump 414 causes the center position of the two pistons 414a, 414b in the hydraulic cylinders 400a, 400b to be varied, with the result that the two tensioner element sections 420a, 420b shorten or lengthen. In this way, the training device can be optimally adapted to the height of the exercising person. It should be noted, however, that a displacement of the center position of the pistons 414a, 414b toward one of the ends of the hydraulic cylinders 400a, 400b has the consequence that the maximum usable stroke of the pistons 414a, 414b in the hydraulic cylinders 400a, 400b, in this Embodiment 400 mm is reduced.

Fig. 6 shows similar to Fig. 4 the training device according to the invention again in the side view, but this time with the hydraulic system according to the second embodiment. In the case of the rocker 16 serving as a rocker housing dashed lines of the hydraulic cylinder 400a is shown, with the piston 414a and the adjoining the piston 414a rod 416a, at the distal end of the guide roller 418a is arranged. The rocker 16 has a connection point 104a, to which the tension element section 420a is firmly connected. From the connection point 104a, the tensioning element section 420a is connected via the deflection roller 418a to the deflected stationary pulley 106, from where the tension member portion 420a is guided to the gripping member 100a.

In the in the Fig. 6 The tensioning element section 420a and the traction element section 420b lying behind it and therefore not shown are thus motion-coupled to the rocker 16 via the attachment points 104a or 104b. The tensioning element section 420a (and similarly the tensioning element section 420b, not shown) is thus exposed to two overlapping movements, namely the voluntary arm movement introduced via the gripping element 100a (or via the gripping element 100b, not shown), and via the connection point 104a It should be noted that the voluntary arm movement of the exercising person usually has a much greater amplitude than the pivotal movement of the rocker 16.

A movement coupling of the tension elements 420a, 420b with the rocker is advantageous for the training effect and is therefore provided according to the invention. Fig. 7 shows a comparative example without such Bewegungsverkopplung. In this embodiment, no deflection rollers are attached to the distal ends of the rods 416a, 416b, but instead articulation points, of which in Fig. 7 again only a Anlenkpunk 422a is shown. The one end of the tension member portion 420a is fixedly attached to the hinge point 422a. From there it is guided by the front wall 20 of the housing of the rocker 16 directly to the deflection 106, without being motion-coupled with the rocker 16. The rest of the structure corresponds to that of the embodiment of Fig. 6 and will therefore not be further elaborated here.

Fig. 8 shows a further variant, according to the embodiment according to Fig. 6 based, ie the motion coupling of Zugseilelements 420a with the rocker 16 has. In this variant is compared to the embodiment in Fig. 6 a further deflection 110 is provided, which may for example depend on a ceiling or a training device associated with the support assembly. By further deflection 110 is achieved; that the exercising person does not have to pull the gripping elements 100a, 100b upwards but instead obliquely downwards. Of course, by providing even more deflections and / or by a different arrangement of the deflections 106, 110, the pulling direction for the exercising person can be further varied.

The two gripping elements 102a, 102b, which are designed as handles or the like, are in Fig. 9 shown. The traction element sections 102a and 102b are fixedly arranged on the gripping elements 100a, 100b, respectively. Fig. 9a shows how the Zugelementabschnitte 102a, 102b are guided from above to the gripper elements 100a and 100b (see. Fig. 8 ). Fig. 9b on the other hand illustrates how the Zugelementabschnitte 102a, 102b are guided from below to the gripping elements 100a, 100b (see. Fig. 4 . 6 and 7 ).
