description

The invention relates to a training device for the stimulation and training of the musculoskeletal system of a person, comprising a person carrying, with respect to a rocker stand pivotal rocker and a drive assembly with at least one engine and a transmission elements having transmission, said transmission elements at least one power transmission chain between the rocker and form the engine.

Such a training device is known from EP 0 929 284 B1. In this, a rocker on which the trainee stands with both legs, driven by an electric motor which is in driving connection with two arranged on both sides of the rocker axis lifting devices. By providing two lifting devices, the drive on two power transmission chains, which extend from the arranged below the rocker axis motor opposite to each other and each other synchronously, but opposite to each other, work, so act in push-pull on the rocker. Such a drive is relatively complex and therefore expensive. In operation, the two lifting devices must be matched exactly to each other, so that they work exactly in opposite directions in opposite directions, and so a smooth pivotal movement of the rocker without internal tension and excessive bearing loads can be achieved. Furthermore, due to the articulated, but otherwise rigid and backlash-free drive of the rocker a jerky force on the rocker, which is not particularly gentle to the joints of the exercising person especially at high stroking frequencies.

The rocker is in the known training device on frame-fixed pedestals stored free of play, so that the rocker always performs the same rocking movements, namely reciprocating pivotal movements about a well-defined, fixed in space pivot axis. Only the frequency of the rocking motion can be changed by setting a desired stroke frequency by means of a control device.

The object of the invention is to provide a training device, in which a joint gentle force introduction is made possible in the rocker, with a simple structure with the associated cost savings in production and maintenance should be considered.

This object is achieved in that at least one transmission element is elastically connected to the rocker or to a fixedly connected to the rocker lever member.

Such elastic connection damps in an advantageous manner at the bottom or top dead center of the pivotal movement occurring shocks or blows. Thus, the rocker can be operated joint-friendly. Furthermore, can be dispensed with such an elastic connection to a costly and wear-underlying pivot bearing for coupling the power transmission chain on the rocker or on the lever element.

It is proposed that the elastic connection is such that the transmission element at least two different elastic

Freedom of movement relative to the rocker or the lever element has.

Preferably, the elastic connection is such that the

Transmission element at least one elastic

Schenkbewegungsfreiheitsgrad relative to the rocker or the lever element has.

Concerning the already mentioned damping of shocks, such an elastic connection is proposed in particular that the Transmission element has at least one elastic degree of freedom of movement in the power transmission direction, in particular for cushioning the rocker in operation via the power transmission chain issued pivotal movement, in particular at the movement direction reversal points.

This results in both cost advantages and significant benefits for the user, namely a more lenient and the body more appropriate implementation of the rocking motion with correspondingly high therapeutic benefits.

Further, it is proposed that at least one leaf spring element is provided for the elastic connection, which allows a relative pivoting between the rocker and the transmission element and / or a cushioning of the rocker during operation granted pivoting movement, in particular at the movement direction reversal points. It is particularly preferred that the at least one leaf spring element itself is a transmission element of the power transmission chain, via which driving forces can be transmitted to the rocker.

Such a leaf spring element has the advantage that it allows the desired elastic mounting and damping of shocks, but with sufficient stability is given to transmit the driving forces on the rocker can.

According to a particularly expedient refinement, it is provided that, for elastic connection, at least two leaf spring elements which are connected one behind the other in the force transmission chain and are elastically deflectable in different, preferably mutually orthogonal directions are provided. Thus, a particularly effective damping effect can be achieved.

Further education but also independent is proposed that the rocker is held elastically with respect to the rocker stand. - A -

Such a holder is structurally simpler and less susceptible to wear in comparison with a known from the prior art swivel bearing. Furthermore, due to the elastic support, in addition to the pivoting movement component, further components of motion superimposed on the pivoting movement component result, which cause the rocker to make small irregular movements. Such a movement pattern, which has as a main component the pivoting movement and other components in different spatial directions, especially preferably also a translational movement component of the rocker in the deflection of a suitably eligible leaf spring element arrangement has an advantageous effect on a training effect of the person using the rocker, since the Body of the person can not adjust to a regularly repeating movement pattern, as is the case for example in the known from the prior art rocker device. The caused by the elastic support of the rocker motion pattern also has no clearly definable effective pivot axis, but it formed in the course of movement, so to speak, several temporary spatially variable axes about which respective partial Teilschwenkbewegungen the rocker be performed. Under certain circumstances, no effective pivot axis can be identified, but the pivoting movement results solely from a spatially distributed deflection / bending of the Blattfederelement- arrangement mentioned here.

It is especially thought that the elastic support of the rocker is such that the rocker has at least two, preferably at least three different elastic degrees of freedom of movement relative to the rocker stand.

Preferably, the elastic attitude is such that the rocker at least one elastic degree of pivotal movement relative to Rocker stand has. A wear-prone and costly pivot bearing can be replaced by a structurally very simple measure, as already mentioned.

It is also proposed that the elastic connection is such that the rocker has at least one elastic degree of freedom of movement in a longitudinal direction of the rocker relative to the rocker stand, in particular for enabling a translatory rocker movement superimposed on the pivoting movement of the rocker. This results in the just mentioned additional movement component, which is superimposed on the pivoting movement and is therapeutically very advantageous. The rocker no longer moves up and down strictly according to a given swivel motion pattern, but may also move in its longitudinal (right and left) directions. This additional movement is dependent on various influences, such as weight, exercise and constitution of the person exercising, etc. Undefined oscillations and additional movements that are superimposed on the lifting movement or the pivoting movement result. It has been shown that the body responds very strongly and positively to such training, since a habituation effect is avoided or at least greatly reduced.

Such a translational movability of the rocker relative to the rocker stand is particularly preferred such that a point on a rocker end moving up and down in a pivoting movement according to a maximum movement stroke at least approximately moves in a path corresponding to a horizontal path. Such a movement path of the rocker movement superimposed on the pivoting movement seems to have a particularly good therapeutic effect. Anyway, a lying eight in eastern medicine is an important and very positive symbol that stands for strong and positive effects on the man.

Preferably, the elastic connection is further such that the rocker has at least one elastic degree of freedom of movement in a vertical direction of the training device relative to the rocker stand, in particular for cushioning the pivoting movement given to the rocker in operation, in particular at the movement direction reversal points. Such cushioning is gentle on the joints and supports the therapeutic effect, as already mentioned in connection with the elastic connection of the transmission element to the rocker or to the lever element.

Tests with patients and with experts have shown that the device according to the invention with the elastic rocker support and the elastic connection of the force transmission chain feels much more harmonious and softer than the device of the prior art without such elasticities.

It is specifically proposed that at least one leaf spring element is provided for elastic support, which has a relative pivoting movement between the rocker and the rocker stand and / or a translational mobility of the rocker in the longitudinal direction relative to the rocker stand and / or mobility of the rocker relative to the rocker stand in one / the high direction of the training device allows.

It is particularly preferred that the at least one leaf spring element is held rocker side and stator side and the pivoting movement of the rocker is carried out relative to the rocker stand by a bending or Torsionsauslenkung of the leaf spring element. In contrast, it is proposed in general terms that the at least one leaf spring element is retained on the rocker side and / or stator side and the pivoting mobility and / or the translational mobility and / or the mobility in the vertical direction of the rocker is effected relative to the rocker stand by a deflection of the leaf spring element or at least one of a plurality of leaf spring elements. in particular bending or Torsionsauslenkung of the leaf spring element or respective Leaf spring element concerning the pivoting movement and in particular bending deflection of the leaf spring element or respective leaf spring element concerning the translational movement and the mobility in the vertical direction.

Particularly expedient for elastic support at least two successively connected, be provided in different, preferably mutually orthogonal directions elastically deflectable leaf spring elements, so that on the one hand a particularly good damping and on the other hand a pronounced, the pivoting movement superimposed additional mobility is achieved.

Since the bending or Torsionsauslenkung is variable depending on the dimensions and material properties of the leaf spring element and depending on the loads acting on the rocker, even small changes in the foot position of the person or / and changes in the lifting height or stroke frequency of the rocker lead to a changed movement pattern so that the advantages already described above are achieved particularly effectively. It should be noted, however, that other spring elements come into question in order to achieve corresponding advantages and effects.

In order to enable the elastic support of the rocker, it is proposed that the rocker stand is designed with a transversely extending to the rocker below this support, wherein it is preferred that along the support a single leaf spring element or a plurality of separate leaf spring elements in the rocker bottom and in the Carrier is clamped / are. The carrier may be rigidly held on a stand assembly of the rocker stand and are considered as part of the rocker stand.

According to an expedient modification, on the other hand, it is provided that the holder of the rocker extends transversely to the rocker below it extending carrier, which is preferably elastically supported on a stator assembly of the rocker stand. Such a carrier can be regarded as part of the elastic support of the rocker on the rocker stand and be held by means of at least one preferably deflectable in the vertical direction leaf spring element on the stator assembly. Also in this case it is preferred that along the carrier a single leaf spring element or a plurality of separate leaf spring elements in the rocker bottom and in the carrier is clamped / are. Accordingly, a single leaf spring element or a plurality of separate leaf spring elements can be clamped on the one hand on the carrier and on the other hand on the stator assembly. It is also possible to provide two leaf spring elements arranged on different sides of the carrier or two leaf spring element groups arranged on different sides of the carrier.

The holder, possibly clamping the leaf spring element or the respective leaf spring element is preferably carried out in a form-fitting manner with the transmission element or with the rocker or with the carrier or the rocker or the stator arrangement. Appropriately, a material-locking connection can be provided, for example by welding, bonding or the like. Such a holder is much easier and less expensive to manufacture in comparison with a hinge assembly with a rocker shaft mounted therein. Furthermore, such a support of the rocker and also the already mentioned elastic connection of the transmission element on the rocker or on a firmly connected to the rocker lever element requires no complex maintenance, in particular no lubrication.

The leaf spring element for the elastic connection of the at least one transmission element and / or for the elastic support of the rocker is preferably made of metal, in particular of steel. In this case, the leaf spring element between the gear element and rocker or lever element or between rocker and rocker stand or carrier have a length of about 1, 0 to 3.0 cm, preferably about 1, 5 to 2.0 cm. Preferably, the leaf spring element is designed with a material thickness of <5.0 mm, preferably about 1, 5 mm. Depending on the type and configuration, the leaf spring element may be formed by a spring steel plate.

Of course, the dimensions mentioned here can also be adapted to other materials in question, so that a desired mounting of the rocker or connection of the transmission element can be achieved.

Furthermore, it is also conceivable, instead of a leaf spring element, in particular made of metal, to use another elastic element, for example made of plastic or rubber or the like, as a connecting or holding element, wherein a dimensioning of such an elastic element must be selected according to the desired operating modes of the rocker , Such an elastic element made of plastic or rubber or the like may be provided in particular as a support for the rocker on the carrier firmly connected to the rocker stand, as acting on this support substantially static forces that have only small dynamic force components when moving the rocker.

The elastically connected transmission element may be a push / pull rod, which is connected with respect to the power transmission chain at its end facing the engine with a trained as an eccentric gear element.

In this case, the eccentric from the engine separately, via a further transmission element of the power transmission chain, in particular via a belt or the like, may be formed connected thereto. A Such a configuration makes it possible to accommodate the motor and the eccentric in a rocker housing such that a good weight distribution and a high stability of the training device is achieved.

Alternatively, it is also possible that the EΞxzenter is arranged directly on an output shaft of the engine.

In a further development, it is further proposed that the drive arrangement has exactly one force transmission chain or a plurality of such force transmission chains running parallel to one another and acting in a common mode on the rocker. This leads to a very simple and thus cost-effective design of the training device. The parallel and acting in a common mode on the rocker arrangement of several power transmission chains has the advantage that the synchronous operation of the various power transmission chains is very simple, in particular much easier than in known opposing power transmission chains can be realized.

It is quite possible, however, that the drive arrangement has at least two power transmission chains acting in push-pull on the rocker. In that regard, a drive could be provided in the manner known from EP 0 929 284 B1 known per se.

It is preferably provided that the force transmission chain or the respective force transmission chain comprises a lifting device acting on the rocker and acting on its underside.

Due to the elastic support of the rocker in combination with the elastic connection of the transmission element, depending on the set rocker amplitude and rocker frequency, a certain additional oscillation of the rocker in different spatial directions can be achieved. These vibrations are irregular with respect to the actual rocker vibration driven by the motor, so that the person using the training device or their body will not be permanently on it can be adjusted, whereby a habituation effect, as it can be observed with only regular oscillations, can be avoided. This has a positive effect on the training effect. Such as a two-dimensional, preferably three-dimensional markable vibration, which is superimposed on the rocking motion, in particular in certain diseases, such as Parkinson's, of great benefit.

Three embodiments of a training device according to the invention will be explained in more detail with reference to the drawings. It shows:

1 is a schematic view of a first embodiment of a training device from behind (omitting the rear wall);

2 is a plan view of the drive of the training device (omitting the rocker),

3 is a side view of the drive according to FIG. 2,

4 shows a schematic view of a second embodiment of the training device,

5 shows a schematic view of a third embodiment of the training device,

Fig. 6 is an enlargement of the designated VI area of Fig. 5 and

Fig. 7 is a schematic view of a suitable for all embodiments of the training device storage.

Fig. 8 shows an enlarged detail of Fig. 5 for explanation an inventively advantageously achievable, superimposed on a pivoting motion path of the rocker.

FIG. 9 shows an alternative embodiment of the rocker of FIG. 5 in a representation corresponding to FIG. 8.

The training device shown in FIG. 1 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 20, a vertical rear wall 19 and vertical side walls 21 and 22 are fastened such that the housing overall forms an open-top box.

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 at a distance to this axis 6 mounted on two bearings 8 and 9 respectively.

On the axis 6 is aligned with the pulley 4, a pulley 7 is attached. About the pulleys 4 and 7 runs a belt 5, which is preferably designed as a toothed belt, but also of a

V-belt or a flat belt can be formed. Alternatively, a drive by means of a chain, a rope, a gear transmission, a bevel gear or the like is possible, with a

Bevel gear, the output shaft of the electric motor 2 is arranged perpendicular to the axis 6.

The bearings 8 and 9 are also mounted by means of fasteners 10 on the base plate 1. In the area of the bearings 8 and 9, two eccentric discs 11 and 12 are attached to the axis 6. At the eccentric discs 11 and 12, 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 a respective rocking lever 14, 14 'is rotatably mounted. The upper ends of the two rocker arms 14, 14 'are by means of a respective Leaf spring element 50 connected to the rocker 16. The leaf spring elements 50 are firmly clamped both on the respective rocker arm 14, 14 'and on the underside of the rocker 16. If now by the rotation of the eccentric discs 11, 12, the rocker arms 14, 14 'are placed in an up / down movement, the leaf spring elements 50 transmit the driving forces on 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 comprises the pulley 4, the belt 5, the pulley 7, the axle 6, the two eccentrics 11, 12, the rocking levers 14, 14 'designed as push rods and the leaf spring elements 50 is formed. The transmission of force is split in parallel on the axle 6 to the two eccentrics 11, 12 and the two rocker arms 14, 14 '. The single power transmission chain in the exemplary embodiment has gear elements arranged parallel to one another here, which execute the same movements during operation and which at the same time belong in the embodiment single drive assembly.

The rocker 16 is mounted in this embodiment in its center on its underside by means of a rocker shaft 23 defining rocker shaft 30, which is mounted in a respective fixed to the front wall 20 and the rear wall 19 of the housing by means of fasteners 18 bearing 17. 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 20 and the rear wall 19 that they can perform an oscillating oscillating or pivoting movement about their rocker axis 23 , However, the gaps between the side edges of the rocker 16 and the walls 19, 20, 21 and 22 are kept so small that no body parts or objects can be pinched.

The amplitude of the oscillating oscillatory 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 from the position of 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 safe 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 contemplated that the rocker arms 14, 14 'are formed such that they are adjustable in length to adjust a mean 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, especially ideal or comfortable for the person foot distance. Furthermore, by an independent of the foot position amplitude adjustment extreme stresses on the rocker, which occur especially when a person transmits their weight through a very wide foot completely outside the rocker, be avoided.

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 electric motor 2 and the lifting device with the axis 6 are preferably arranged on different sides of the rocker axis 23. The bearings 8 and 9 for the axle 6 and the bearings 15 at the bottom of

Rocker 16 preferably arranged in the outer quarter of the length L, while the heavier electric motor 2 is arranged closer to the center of the housing. Overall, this results in a balanced weight distribution, which facilitates the wearing of the training device. The

Eccentric discs 11 and 12 or the axis 6 can with

Balancing weights be provided to prevent unwanted vibration at the

Avoid housing. The rocker 16 is formed as a stable plate, optionally with additional stiffeners, so that no vibrations can occur due to changing bending loads.

The rocker 16 is preferably designed in terms of the forces acting as an aluminum plate, on its underside in the embodiment Has not shown struts. The orientation and dimensions of the struts are chosen so that the rocker learns by the unilateral parallel introduction of force by means of the two rocker arms 14, 14 'no significant bending or / and twisting. The formation of struts is preferably carried out by milling of recesses in the metal plate, which in addition to the desired stiffness leads to a reduction in weight.

The training device is further preferably equipped with a direction indicated in Fig. 1 control unit 24, which has 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 can be accessed as needed. By means of such a control device and the above-mentioned actuators of the adjusting elements for

Amplitude variation are 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 handrail, not shown, known from the aforementioned prior art, which is attached, for example, to the front wall 20 and extends approximately at the chest height of the user. However, it can also be done for example by rotary switches on a side wall 22 of the housing.

According to the second embodiment schematically shown in Fig. 4, the training device also comprises an open-topped housing with a base plate 1, are attached to the two side walls 21 and 22 and two front and rear walls, not shown. At a distance from the walls, a rocker 16 is inserted in the form of a rectangular plate in the open top of the housing. The rocker 16 is in its longitudinal center by means of a rocker shaft 30 in pivot bearings in the front and not shown Rotatably mounted rear walls and is offset by a drive described below in an oscillating oscillation about the rocker axis 23. Only the differences from the exemplary embodiment of FIGS. 1 to 3 will be explained below.

The drive comprises an electric motor 2, which is attached to the base plate 1 under one, in the figure 4, the right side of the rocker 16. The electric motor 2 is controllable with respect to its speed and connected via an eccentric with the underside of the rocker 16 in the region of the rocker shaft 30 for rotational force introduction into the rocker 16. Alternatively, the eccentric with the rotatably connected to the rocker 16 rocker shaft 30 are in communication. Finally, the advantageous principle of a central rotary drive of the rocker 16 can also be realized by a direct drive of the rocker shaft 30 and the rocker rotatably mounted thereon by a reversible electric motor.

The output axis of the electric motor 2 is fixedly connected to an eccentric disc 26 which carries an eccentric pin 27.

One end of a rocker arm 28 is fixedly connected to the underside of the rocker 16 in the region of the shaft 30. The other end of the rocker arm 28 is connected via a power transmission rod 29 with the eccentric pin 27 of the eccentric 26. The power transmission rod 29 is elastically connected by means of a leaf spring member 52 with the lower end of the rocker arm 28 and the eccentric pin 27. The lower end of the rocker arm 28 comes to rest at a distance above the base plate 1.

Thus, the power transmission chain of the transmission in the second embodiment includes the eccentric 26 with its eccentric pin 27, the power transmission rod 29, the leaf spring member 52 and the rocker arm 28. Together with the motor 2, they form the only drive assembly. It should be noted that the parallel arrangement of a second such transmission, either with the the same engine (such as at the other end of the motor shaft) or connected to a synchronously running second motor is conceivable. This would result in two power transmission chains, which run parallel to each other and operate in common mode.

A rotary movement of the electric motor 2 causes the eccentric disk 26 to rotate, the eccentric pin 27 of which carries the end of the power transmission rod 29 hinged thereto, the rotational movement of which is transmitted to the lower end of the rocker arm 28 by means of the elastically behaving leaf spring element 52. Since the upper end of the rocker arm 28 is fixed to the rocker 16, the rocker 16 is rotated about its rocker axis 23, which leads to the oscillating oscillation or pivotal movement of the rocker 16. In this case, as described in the first embodiment damping of shocks is achieved by the leaf spring member 52.

Of course, adjustment possibilities can also be provided on the transmission elements in this embodiment, so that the amplitude of the pivoting movement is adjustable.

In an analogous manner as in the first embodiment, a training device according to the second embodiment may be connected to a not shown in FIG. 4, but similar to FIG. 1 control unit.

5, a third 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 housing of the training device, in particular the walls 19, 20 or a different stand assembly , attached carrier 56 is held. The carrier 56 is attached to the front wall 19 and the rear wall 20 (see Fig. 2) 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 materially engaged at 58. An upwardly facing end of the leaf spring element 54 is clamped at 60 in the rocker 16. Between these two Einspannungsbereiche 58 and 60, the leaf spring element 54 is free and can bend relative to the Fig. 6 to the left and to the right, so that 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, in such a support of the rocker 16 no fixed pivot axis is set, as is the case with a pivot bearing according to the embodiment of FIG. 1, since the extent of the deflection and the exact course of a deflection of the leaf spring element 54 is influenced by different factors, such as for example, the weight of the person standing on the rocker, the foot position of the person, 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 inventive elastic support of the rocker 16 can be achieved that this performs the actual pivotal movement superimposed translational movement, such that a reference point at a rocker end of a lying eight corresponding trajectory follows, as indicated in Fig. 8 by the trajectory B. ,

It should be noted that instead of extending in the cross-section in the vertical direction leaf spring elements in the 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 the rocker arm on the rocker to cushion the upper and lower reversal point (dead center). It is also possible for a plurality of series-connected spring elements, in particular leaf spring elements, to be provided, as realized in the embodiment variant resulting from FIG. 9. The oscillating lever 14 is connected to the rocker 16 via a first, approximately horizontally oriented spring element 50a, an intermediate piece 14a and a second, approximately vertically oriented leaf spring element 50. The rocker bearing takes place via a likewise elastically mounted carrier 56, which is held elastically on first, in cross-section approximately horizontally extending leaf spring elements 54a to a stator assembly 56a. Between the carrier 56 and the rocker 16 is also a leaf spring element 54 corresponding to the leaf spring element 54 of FIG. 5 is effective.

It should be noted that the pivoting motion does not require a large stroke at the rocker ends to achieve a therapeutic effect. For example, with a rocker having a length of 80 cm from one end to the other end, a maximum stroke at the ends of about 12 mm may be provided. With regard to the translatory movement of the rocker, it may be provided that a translatory design of approximately 2 mm superimposed on the pivoting movement occurs, so that in the case of the movement path B according to FIG. 8, the lying eight has a length of approximately 2 mm. The depth of the rocker may be, for example, 40 cm, so that, for example, a plate of dimension 40 x 80 cm can be used for the provision of the rocker.

In particular, the embodiment of FIG. 9 is particularly effective to absorb and dampen stroke peaks and reversals of movement particularly effective.

The leaf spring element 54, like the carrier 56, may be formed continuously from the front side to the rear side, wherein it is not connected directly to the housing when clamped in the carrier 56. But it is also conceivable that in the carrier 56 a plurality of separate Leaf spring elements are provided. A corresponding embodiment is due to the operating conditions to be met or maximum loads, which act during operation on such an elastic rocker bracket. In a corresponding manner, the leaf spring elements 54a could be formed.

In addition to the arrangement of one or more leaf spring elements below the rocker, it is also conceivable to arrange one or more leaf spring elements on the rocker so that they protrude on the front or back of the rocker and are connected directly to the housing. In such an arrangement, a pivotal movement of the rocker is made possible by a Torsionsauslenkung the leaf spring elements, and it can also be easily achieved an effective cushioning in the vertical direction.

By using leaf spring elements 50, 52, 54 according to the presented embodiments can be dispensed with in each case at least one pivot bearing assembly, which allows a simplified and inexpensive construction of the training device. Furthermore, the maintenance effort is reduced since a holder or connection by means of a leaf spring element has no rubbing wear parts, in which lubrication is necessary.

Referring to Fig. 7, a possibility of mounting the exerciser on the ground will be described. The housing of the training device, in particular its front wall 20 and the base plate 1, are shown schematically. The accommodated in the housing drive assembly or rocker bracket may be formed according to one of the embodiments described above and will not be described in detail here. The housing lies with its base plate 1 on four bearing elements 32, two of which are shown and which are themselves supported on a base plate 34 of the training device. The base plate 34 is in turn by appropriate feet 36 on the floor 38th supported non-slip, so that the base plate 34 does not move relative to the ground 38 in rocker operation. Of course, the bearing elements 32 are secured to the base plate 1 of the housing or the base plate 34 in a suitable manner.

As bearing elements 32 tubular rubber parts are used, wherein the two rubber parts 32 shown are aligned differently with respect to the front wall 20, so that movements of the housing in orthogonal to each other, horizontal spatial directions can be uniformly absorbed. Of course, however, all rubber parts of such storage can be aligned the same.

On the base plate 34, a holding device 40 is mounted, which has two vertically extending from the base plate 34 upwardly extending rods 42, which are interconnected via a horizontal connecting piece 44 at their upper ends. Since the holding device 40 is connected to the base plate 34, the housing and the rocker mounted therein can move freely relative to the base plate 34 and the holding device 40, in particular with three spatial degrees of freedom.

The described storage of the housing allows oscillation of the housing and the associated rocker in any spatial directions, these vibrations must be compensated by the body of the person standing on the rocker, which positively affects the training effect for the person.

The irregularity of the vibrations caused by the bearing of the housing can be intensified even more when the rocker is held in an elastic manner (cf., FIGS. 5 and 6), so that the training effect can be further advantageously supported.

At the connector 44, for example, a not shown Screen, in particular touch screen, or another interface device to be mounted, which is or connected to the control unit 24 shown in Figure 1 and allows the adjustment of the control unit 24 by the person standing on the rocker. Of course, the rods 42 and the connector 44 may also be integrally formed with each other. The holding device 40 makes it easier for the person using the training device to ascend / descend onto or from the rocker floating with respect to the floor 38. Furthermore, the holding device also allows the person during the rocking, if it can not hold the balance for a short time or if an adjustment of the rocking frequency and / or amplitude is performed.
