Description

The The invention relates to a training device for stimulation and training the musculoskeletal system of a person comprising a person carrying, in terms of a seesaw stand pivotable rocker and a drive assembly with at least one Engine and a gearbox having gear, wherein the Transmission elements at least one power transmission chain between the Form the rocker and the engine.

Such a training device is from the EP 0 929 284 B1 known. 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 has two power transmission chains, which extend from the motor arranged below the rocker axis opposite to each other and each other synchronously, but counter 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 free of play in the known training device on frame-fixed pedestals stored, so that the rocker always performs the same rocking movements, and while reciprocating pivotal movements around a well-defined, fixed in the room pivot axis. It can only change the frequency of the rocking motion changed be by a desired Hub frequency is set by means of a control unit.

task The invention is to provide a training device in which a a joint-friendly introduction of force into the rocker is made possible, whereby a simpler Construction with the associated cost savings in production and maintenance shall be.

These Task is solved by that at least one transmission element on the rocker or at one with the rocker firmly connected lever element is connected elastically.

A dampens such elastic connection advantageously at the bottom or top dead center of the pivoting movement occurring impacts or Punches. Thus, the rocker can be operated joint-friendly. Furthermore, can by such elastic connection to a costly and wear-underlying Swivel bearing for coupling the power transmission chain to the rocker or to be dispensed with the lever element.

It It is proposed that the elastic connection is such that the transmission element at least two different elastic degrees of freedom of movement relative to the rocker or the lever element has. Preferably the elastic connection such that the transmission element at least an elastic Schenkbewegungsfreiheitsgrad relative to the rocker or to the lever element has.

Concerning the already mentioned damping of bumps in particular proposed such elastic connection, that the transmission element at least one elastic degree of freedom of movement in power transmission direction has, in particular for cushioning the rocker in operation over the Power transmission chain granted pivotal movement, in particular at the movement direction reversal points.

It This results in both cost advantages and significant advantages for the User, namely a joint-sparing and the body more appropriate implementation the rocking movement with correspondingly high therapeutic Use.

A development It is proposed that at least one elastic connection Leaf spring element is provided, which has a relative pivoting between the rocker and the transmission element and / or a suspension the rocker in operation given pivoting movement in particular allows at their movement reversal points. It is special preferred that the at least one leaf spring element itself Transmission element of the power transmission chain is over which driving forces transferable to the seesaw are.

One such leaf spring element has the advantage that it is the desired elastic Storage and damping of shocks, but with sufficient stability to drive forces transfer the rocker to be able to.

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. So can a particularly effective steaming be achieved.

A development but also independent It is proposed that the rocker with respect to the rocker stand elastic is held.

A such bracket is compared with one of the prior art known pivot joint construction structurally simpler and less susceptible to wear. Further arise through the elastic support in addition to the pivoting movement component further components of motion superimposed on the pivoting movement component, which cause that the seesaw has little irregular movements performs. Such a movement pattern, the pivoting movement as the main component and further components in different spatial directions, especially preferably also a translational motion component of Rocker in the deflection of a suitably eligible leaf spring element arrangement acts beneficial to a training effect of using the rocker Person out, since the body of the Person not on a regularly repeating Movement pattern can set, as for example in the known from the prior art rocker device is the case. The movement pattern caused by the elastic support of the rocker also has no clearly definable effective pivot axis, but in the course of the movement, so to speak, several are formed temporary location-variable axes to which respective temporary partial pivoting movements of the Rocker performed become. It may even be possible no effective pivot axis are identified, but the pivoting movement results alone from a spatially distributed deflection / bending of the leaf spring element assembly discussed here.

It is particularly thought that the elastic holder of Rocker is such that the rocker at least two, preferably at least three different elastic degrees of freedom of movement relative to seesaw stand Has.

Prefers is the elastic attitude such that the rocker at least one has elastic Schwenkbewegungsfreiheitsgrad relative to the rocker stand. A wear-prone and costly pivot bearing can be so by a constructive very simple measure be replaced, as already mentioned.

Further It is proposed that the elastic connection is such that the rocker at least one elastic degree of freedom of movement a longitudinal direction the rocker has relative to the rocker stand, in particular to enable one of the pivotal movement of the rocker superimposed translational Rocker movement. It thus results in the just mentioned additional Movement component superimposed on the pivoting movement and therapeutic is very beneficial. The rocker no longer moves strictly a given swing motion pattern up and down, but can also in their longitudinal direction move (to the right and left). This extra movement is dependent on different influences, like weight, exercise and constitution of the exercising person, etc. It results in undefined Vibrations and additional movements, the lifting movement or the Swivel motion superimposed are. It has been shown that the body is very training on such strongly and positively reacts, since a habituation effect avoids or at least very much reduced.

Especially preferred is such a translational mobility of the rocker relative to the rocker stand, a point on one in the pivotal movement according to a maximum movement stroke up and down moving rocker end at least nearly moving on a track that is in line with a lying eight. Such a movement path of the pivoting movement superimposed Rocker movement seems to have a particularly good therapeutic effect to have. Anyway, a lying eight in the eastern Medicine is an important and very positive symbol for strong and positive impact on the man.

Prefers the elastic connection is further such that the rocker at least an elastic degree of freedom of movement in a vertical direction of the exercise machine relative to the rocker stand has given, in particular for cushioning the rocker in operation Pivoting movement, in particular at their direction of movement reversal points. Such cushioning is gentle on the joints and supports the therapeutic effect, as already associated with the elastic Connection of the transmission element on the rocker or addressed to the lever element.

Testing with patients and with professionals have shown that the device according to the invention with the elastic rocker bearing and the elastic connection of the power transmission chain feels much more harmonious and softer than the prior art device 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-way up of the training device allows.

there it is particularly preferred that the at least one leaf spring element rocker side and stand side is held and the pivoting movement of the rocker relatively through to the rocker stand a bending or Torsionsauslenkung the leaf spring element takes place. In contrast, generalized, it is proposed that the at least one leaf spring element rocker side and / or stand side is held and the pivoting movement and / or the translational Mobility and / or mobility in the vertical direction of the seesaw relative to the rocker stand by a deflection of the leaf spring element or at least one of several Leaf spring elements, in particular bending or torsional deflection of the leaf spring element or respective leaf spring element concerning the pivoting mobility and in particular bending deflection of the leaf spring element or respective Leaf spring element regarding the translational mobility or the mobility in the vertical direction.

Especially can be useful for elastic holder at least two in series, in different, preferably mutually orthogonal directions be provided elastically deflectable leaf spring elements, so that on the one hand a particularly good damping and on the other hand, a distinct, the pivoting movement superimposed additional Agility is achieved.

There the bending or torsion deflection depending on the dimensions and Material properties of the leaf spring element and depending on the On the rocker acting loads changeable already lead small changes the foot position the person or / and changes in the lifting height or stroke frequency of the rocker to a changed movement pattern, so that the advantages already described above achieved particularly effective become. It should be noted, however, that other spring elements in question come to achieve the appropriate benefits and effects.

Around to allow the elastic support of the rocker, it is proposed that the rocker stand with a transversely extending to the rocker below this extending carrier, it being preferred that along the carrier a single leaf spring element or a plurality of mutually separate leaf spring elements in the rocker base and in the carrier is / are clamped. The carrier can be rigid on a stand arrangement of the rocker stand be considered as part of the seesaw stand.

According to one appropriate modification is in contrast provided that the holder of the rocker is a transverse to the rocker below this extending support, preferably elastic on a stator assembly of the rocker stand is held. Such a carrier Can be considered as part of the elastic support of the rocker on the rocker stand be and for example by means of at least one preferably vertically deflectable leaf spring element on the stator assembly be held. Also in this case it is preferable that along of the carrier a single leaf spring element or a plurality of separate leaf spring elements is clamped in the rocker base and in the vehicle. Corresponding may be a single leaf spring element or a plurality of separate leaf spring elements on the one hand on the carrier and on the other hand, on the stator assembly be clamped. It can also arranged on different sides of the carrier leaf spring elements or two arranged on different sides of the carrier leaf spring element groups be provided.

The Holder, possibly clamping the leaf spring element or the respective Leaf spring element is preferably a positive fit with the transmission element or with the rocker or with the carrier or the rocker or the Ständeraordnung. Appropriately also a material-locking Provided connection, for example by welding, bonding or similar. Such a holder is compared with a Swivel assembly with a rocker shaft mounted therein clearly easier and cheaper manufacture. Further needed Such a support of the rocker and also the already mentioned elastic connection of the gear element on the rocker or on a with the rocker firmly connected lever element no complex maintenance, especially 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 made of steel.

there the leaf spring element between the gear element and rocker or Lever or between rocker and rocker stand or carrier a length of about 1.0 to 3.0 cm, preferably about 1.5 to 2.0 cm. Preferably, the leaf spring element with a material thickness of <5.0 mm, preferably about 1.5 mm executed. Depending on the type and configuration, the leaf spring element of a Be formed spring steel plate.

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

Further It is also conceivable, in place of a leaf spring element in particular metal another elastic element, such as plastic or rubber or the like as the attachment member to use, with a dimensioning of such an elastic element according to the desired Operating modes of the rocker selected must become. Such an elastic element made of plastic or Rubber or the like can in particular as a holder for the rocker on the one with the rocker stand firmly connected carrier be provided because of this holder substantially static personnel act when moving the rocker only small dynamic force components exhibit.

The elastically connected transmission element can be a push / pull rod be related to the power transmission chain at its end facing the engine with a trained as an eccentric Transmission element is pivotally connected.

there the eccentric from the engine separately, via another transmission element the power transmission chain, especially about a belt or the like may be formed connected thereto. Such a design allows it to accommodate the motor and the eccentric in such a rocker housing, that a good weight distribution and high stability of the training device is reached.

alternative this is also possible in that the eccentric is arranged directly on an output shaft of the motor is.

A development It is also proposed that the drive arrangement be exactly one Power transmission chain or more such, mutually parallel and in common mode Power transmission chains acting on the rocker having. this leads to a very simple and thus inexpensive construction of the training device. The parallel and in common mode acting on the rocker arrangement of several Power transmission chains has the advantage that the synchronous operation of the various Power transmission chains very simple, in particular much easier than in known opposing Power transmission chains is feasible.

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 in the way as from the EP 0 929 284 B1 be known per se.

Prefers is provided that the power transmission chain or the respective power transmission chain an acting on the rocker, attacking on the underside lifting device includes.

By the elastic support of the rocker in combination with the elastic Connection of the gear element can, depending on the set rocker amplitude and rocker frequency some additional vibration of the rocker be achieved in different directions. These vibrations are opposite the actual rocker vibration driven by the motor irregular, like that that is the training device using person or her body can not permanently adjust to this, creating a habituation effect, like him with only regular vibrations is observed, can be avoided. This has a positive Effect on the training effect. Such as two-dimensional, preferably three-dimensional characterizable oscillation, which the Rocking motion superimposed is, in particular in certain diseases, such as Parkinson's, of great benefit.

following become three embodiments a training device according to the invention below Reference to the drawings closer explained. It shows:

1 a schematic view of a first embodiment of a training device from behind (with the back wall omitted);

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

3 a side view of the drive according to 2 .

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

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

6 an enlargement of the area of the 5 and

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

8th shows an enlarged section of the 5 for explaining an inventively achievable, superimposed on a pivoting movement path of the rocker.

9 shows a variant of the rocker of 5 in a representation accordingly 8th ,

This in 1 Training device shown is composed of a serving as a rocker stand housing with a base plate arranged in the lower region 1 , on the one vertical front wall 20 , a vertical back wall 19 and vertical side walls 21 respectively. 22 are fastened such that the housing forms a total open-topped box.

At the base plate 1 is an electric motor 2 trained drive by means of several fasteners 3 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 to this one axis 6 at two camps 8th respectively. 9 stored. On the axis 6 is aligned with the pulley 4 a pulley 7 attached. About the pulleys 4 and 7 a belt is running 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 perpendicular to the axis 6 is arranged.

Camps 8th respectively. 9 are by means of fasteners 10 also on the base plate 1 stored. In the field of bearings 8th respectively. 9 are on the axis 6 two eccentric discs 11 respectively. 12 attached. At the eccentric discs 11 and 12 is in each case parallel to the axis 6 in alignment with each other an eccentric pin 13 arranged. At the eccentric bolt 13 is the lower end of each rocker arm 14 . 14 ' rotatably mounted. The upper ends of the two rocker arms 14 . 14 ' are by means of a respective leaf spring element 50 with the seesaw 16 connected. Here are the leaf spring elements 50 both on the respective rocker arm 14 . 14 ' as well as on the underside of the rocker 16 firmly clamped. If now by the rotation of the eccentric discs 11 . 12 the rocker arms 14 . 14 ' be placed in an up / down movement, transfer the leaf spring elements 50 the driving forces on the rocker 16 , so this around the rocker axis 23 is pivoted. 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 dimensioned so that they are the acting driving forces safely on the rocker 16 can transmit, so that the training device can be operated reliably.

In this embodiment, a drive arrangement starting from the electric motor 2 a power transmission chain coming from the pulley 4 , the belt 5 , the pulley 7 , the axis 6 , the two eccentrics 11 . 12 the trained as push rods swing levers 14 . 14 ' and the leaf spring elements 50 is formed. The power transmission is on the axle 6 on the two eccentrics 11 . 12 and the two rocker arms 14 . 14 ' split in parallel. 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 seesaw 16 is in this embodiment in its center on its underside by means of a rocker axis 23 defining rocker shaft 30 stored in each one on the front wall 20 and on the back wall 19 of the housing by means of fasteners 18 fortified warehouse 17 is stored. The seesaw 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 the seesaw 16 is arranged almost flush with the upper edge of the housing, but to the side walls 21 respectively. 22 and to the front wall 20 and to the back wall 19 has so much play that they oscillate oscillating or pivoting about their rocker axis 23 can perform. The gap between the side edges of the rocker 16 and the walls 19 . 20 . 21 and 22 however, are kept so small that no body parts or objects can be trapped.

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 middle of the axis 6 , It also depends on the length of the rocker arm 14 or from the position of a connection 15 the rocker arm on the rocker off. Preferably, the amplitude is variable in the range of 1 mm to about 40 mm. Such amplitude variability can be achieved, for example, by a set of interchangeable eccentric discs whose eccentric pins are at different distances from the rotator 6 exhibit. Furthermore, it can be thought of in the unchanged used to use eccentrics, the connection 15 slidably fastened to the rocker in the direction orthogonal to the rocker axis. 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 thought that the rocker arms 14 . 14 ' are formed so that they are adjustable in length to adjust a mean horizontal or tilt of the rocker. Of course they are to set the amplitude as needed combinations of said adjustment options on the various transmission elements possible. 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 his feet more or less far to the right and left of the rocker axis 23 on the seesaw 16 placed.

A adjustment the swing amplitude independently from the mentioned Change in the stance on the seesaw has the advantage that the training effect at consistent, in particular ideal or comfortable for the person foot distance elevated can be. Furthermore, by one from the foot position independent Amplitude adjustment Extreme loads on the rocker, which in particular Then, when a person's weight through a very wide Foot position completely Outside transfers to the seesaw, avoided become.

Furthermore, the speed of the electric motor is preferably 2 variable, allowing for the frequency of the oscillating motion of the rocker 16 set a range of about 3 to 70 Hz. The speed change of the electric motor 2 is preferably done by a frequency converter.

The electric motor 2 and the lifting device with the axle 6 are preferred on different sides of the rocker axis 23 arranged. Here are the bearings 8th respectively. 9 for the axis 6 and the camps 15 at the bottom of the seesaw 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 respectively. 12 or the axis 6 may be provided with balance weights to avoid unwanted vibration on the housing. The seesaw 16 is designed as a stable plate, optionally with additional stiffeners, so that no vibrations can occur due to changing bending loads.

The seesaw 16 is preferably designed as an aluminum plate with respect to the forces acting on the underside in the exemplary embodiment, not shown struts. The orientation and dimensions of the struts are chosen so that the rocker by the unilateral parallel introduction of force by means of the two rocker arms 14 . 14 ' no significant bending or / and twisting experiences. 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 with a in 1 indicated control unit 24 equipped with a program memory 25 in which a plurality of different training programs each having a different time profile of the frequency and / or the amplitude of the oscillating oscillatory movement of the rocker 16 stored and available 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 use the program memory 25 equipped variant as well as in a simpler variant manually adjust the frequency and / or amplitude. The adjustment of the parameters is preferably carried out on a handrail, not shown, known from the aforementioned prior art, for example, on the front wall 20 is attached and goes up about the chest height of the user. However, it can also, for example, by rotary switch on a side wall 22 of the housing.

According to the in 4 schematically illustrated second embodiment, the training device also includes an open-topped housing with a base plate 1 , on the two side walls 21 and 22 and two not shown front and rear walls are attached. At a distance to the walls is a seesaw 16 used in the form of a rectangular plate in the open top of the housing. The seesaw 16 is in its longitudinal center by means of a rocker shaft 30 rotatably mounted in pivot bearings in the front and rear walls, not shown, and is characterized by a drive described below in an oscillating oscillation about the rocker axis 23 added. In the following, only the differences from the embodiment of 1 to 3 explained.

The drive includes an electric motor 2 who is at the base plate 1 under one, in the 4 the right side of the seesaw 16 is attached. The electric motor 2 is controllable in terms of its speed and an eccentric with the underside of the rocker 16 in the area of the rocker shaft 30 for torque input into the rocker 16 connected. Alternatively, the eccentric with the rotatable with the rocker 16 connected rocker shaft 30 keep in touch. Finally, the advantageous principle of a central rotary drive of the rocker 16 also by a direct drive of the rocker shaft 30 or the rocker rotatably mounted thereon are realized by a reversible electric motor.

The output axis of the electric motor 2 is fixed with an eccentric disc 26 connected to an eccentric pin 27 wearing.

One end of a rocker arm 28 is in the range of the wave 30 firmly with the underside of the rocker 16 connected. The other end of the rocker arm 28 is via a power transmission rod 29 with the eccentric bolt 27 the eccentric disc 26 connected. The transmission rod 29 is elastic by means of a leaf spring element 52 with the lower end of the rocker arm 28 and the eccentric bolt 27 connected. The lower end of the rocker arm 28 comes at a distance above the base plate 1 to lie.

Thus, the power transmission chain of the transmission in the second embodiment includes the eccentric disc 26 with its eccentric bolt 27 , the transmission rod 29 , the leaf spring element 52 and the rocker arm 28 , Together with the engine 2 they form the only drive arrangement. It should be noted that the parallel arrangement of a second such transmission, which is connected either to the same engine (approximately at the other end of the motor shaft) or 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 motion of the electric motor 2 displaces the eccentric disc 26 in rotation, the eccentric pin 27 the end of the power transmission rod hinged to it 29 entrains, the rotational movement by means of the elastically behaving leaf spring element 52 on the lower end of the rocker arm 28 is transmitted. Because the upper end of the rocker arm 28 on the seesaw 16 is fixed, the rocker 16 around her rocker axis 23 set in rotation, causing the oscillating oscillation or pivoting movement of the rocker 16 leads. It is characterized by the leaf spring element 52 achieved as described in the first embodiment damping of shocks.

Of course you can too in this embodiment adjustment be provided on the transmission elements, so that the amplitude of Swivel movement is adjustable.

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

In the 5 a third embodiment of the training 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 elastic on a on the housing of the training device, in particular the walls 19 . 20 or a different stator assembly, mounted carrier 56 is held. The carrier 56 is on the front wall 19 and the back wall 20 (see. 2 ) and extends over the entire width of the housing. At the top of the carrier 56 is the leaf element 54 positive fit and preferably material fit at 58 clamped.

An upwardly facing end of the leaf spring element 54 is at 60 in the seesaw 16 clamped. Between these two clamping areas 58 and 60 is the leaf spring element 54 free and can be relative to the 6 bend to the left and to the right, allowing a pivoting of the rocker 16 due to the rocker arm 14 on the seesaw 16 transmitted driving force can be done. It is in such a holder of the rocker 16 fixed no fixed pivot axis, as in a pivot bearing according to the embodiment of 1 the case is because the amount of bending and the exact course of a deflection of the leaf spring element 54 is 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 element 54 to the left and to the right.

Advantageously, by means of the inventive elastic holder of the rocker 16 be achieved that this one of the actual pivotal movement superimposed translational movement performs, such that a reference point follows a rocker end of a lying a corresponding eight trajectory, as in 8th indicated by the movement path B.

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

It can also be several successively connected spring elements, in particular leaf spring elements, may be provided as in the itself 9 realized implementation variant. Of the rocker 14 is about a first, approximately horizontally oriented spring element 50a , an intermediate piece 14a and a second, approximately vertically oriented leaf spring element 50 on the seesaw 16 tethered. The rocker bearing takes place via a itself also elastically mounted carrier 56 , the first about, in cross-section approximately horizontally extending leaf spring elements 54a on a stand assembly 56a is held elastic. Between the carrier 56 and the seesaw 16 is also a leaf spring element 54 according to the leaf spring element 54 of the 5 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. Concerning the translatory movement of the rocker it can be provided that a translatory design of about 2 mm superimposed on the pivoting movement occurs, so that in the case of the movement path B according to FIG 8th the lying eight has a length of about 2 mm. The depth of the rocker may be, for example, 40 cm, so that, for example, a plate of dimension 40 × 80 cm can be used for the provision of the rocker.

In particular, the embodiment of 9 is particularly effective in cushioning and dampening stroke tips and reversals of movement.

The leaf spring element 54 can be like the carrier 56 be formed continuously from the front to the back, and it is when clamped in the carrier 56 not directly connected to the housing. 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 be educated.

Next the arrangement of one or more leaf spring elements below the Rocker, it is also conceivable, one or more leaf spring elements on to arrange the rocker that they are on the front or back protrude the rocker and are connected directly to the housing. In such an arrangement, a pivoting movement of the rocker is through a Torsionsauslenkung the leaf spring elements allows and it can do that as well simply an effective cushioning in the vertical direction can be achieved.

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 7 a possibility of storage of the training device on the ground is described. The housing of the training device, in particular its front wall 20 and its 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 of which two are shown and the ones themselves on a base plate 34 are supported by the training device. The base plate 34 is in turn by appropriate feet 36 on the ground 38 non-slip supported, so that the base plate 34 in rocker mode not relative to the ground 38 emotional. Of course, the bearing elements 32 at the base plate 1 of the housing or the base plate 34 fastened in a suitable manner.

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

At the base plate 34 is a holding device 40 attached, which two are vertically from the base plate 34 upwardly extending rods 42 which has a horizontal connector 44 are connected together at their upper ends. As the holding device 40 with the base plate 34 is connected, the housing and the rocker mounted therein can relative to the base plate 34 and the holding device 40 move freely or swing, especially with three spatial degrees of freedom.

The described storage of the housing allows a Vibration of the housing and the associated rocker in any spatial directions, these vibrations being through the body of the rocker Person need to be compensated what the training effect for the Person influenced positively.

The irregularity of the vibrations caused by the bearing of the housing can, in particular with elastic retention of the rocker (cf. 5 and 6 ), so that the training effect can be further advantageously supported.
