A gear unit provides power transmission chains between the see-saw and an output unit (4) of a motor. The drive arrangement has exactly one power transmission chain or the set of power transmission chains running parallel to each other and acting in a common mode on the see-saw.

Description

The invention relates to a training device for the stimulation and training of the musculoskeletal system of a person, in particular for the stimulation of muscles, tendons and / or bones, comprising a person supporting, a rocker axis pivotable rocker and at least one drive assembly with at least one drivable output element having the motor and with a rocker with the output element bewegungsverkoppelnden, gear elements having gear so that the rocker is displaceable by means of the drive assembly in an oscillating pivotal movement about the rocker axis, wherein the transmission elements form at least one power transmission chain between the rocker and the output element of the motor.

Such a training tool is known from EP 0929284 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 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.

The object of the invention is to provide a training device that has a simpler structure with the associated cost savings in production and maintenance.

This object is achieved in that the drive arrangement has in a generic training device exactly one force transmission chain or more such mutually parallel and acting in a common mode on the rocker power transmission chains.

A drive assembly designed in this way has a very simple and therefore cost-effective design, especially in the case of exactly one power transmission chain. A simple structure is also given in several power transmission chains, which preferably have identical transmission elements. 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 very simple, in particular much easier than in known counter-rotating power transmission chains, can be realized.

Preferably, the or at least one power transmission chain has gear elements which are parallel to one another in sections. This allows, for example, the stable support of the rocker on a plurality of parallel arranged transmission elements. Such a power transmission chain also makes it possible to divide the power flow in parallel, so that the total load distributed to the individual transmission elements arranged parallel to one another and thus the load on the individual transmission element can be reduced.

Particularly preferred is exactly acting between the motor and the rocker drive assembly to achieve the simplest possible construction of the rocker.

To two rotating or reciprocating gear elements, For example, a motor driven pulley and an eccentric arranged therefrom to couple, a transmission element may be formed as a circumferential, elongate force transmission element, in particular as a chain or a belt.

The power transmission chain preferably has at least one pair of articulated interconnected elements from the group of thrust element, lifting element, tension element, lever element and crank element, so that depending on the arrangement of the engine and depending on the configuration of the connection between the power transmission chain and the rocker, the power transmission chain structurally simple and can be made up of comparatively few parts. In this case, the or at least one crank element can be designed as an eccentric, in particular eccentric disk.

According to a first alternative development, a coupling point at which the force transmission chain is coupled to the rocker is offset relative to the rocker axis in the direction of one end of the rocker, wherein preferably a push or pull element of the power transmission chain is articulated to the coupling point. One of the rocker axis offset to one end of the rocker Ankoppelstelle allows due to the other, not coupled with a power transmission chain end of the rocker overall a less hard perceived change of direction of the reciprocation, since the rocker due to their other, free end of the push or Tensile element can dampen transmitted forces by their own elasticity.

In this context, the eccentric can be arranged offset relative to a central plane containing the rocker axis on the same side, on which the power transmission chain is connected to the rocker. As a result, the hinged on the rocker and connected to the eccentric cam via an eccentric shear or tension element may be relatively short, and between the eccentric and the Rocker extend substantially vertically. This allows an optimum for the generation of the pivoting force introduction of force by means of the thrust element.

In order to achieve a good force distribution and a suitable effective Hebelarmlänge, it is proposed that the power transmission chain or the push or pull element is connected in the outer quarter of a rocker extension between the ends of the rocker with this.

So that the center of gravity of the training device is located in a central region, in particular below the rocker axis, and in order to enable an overall compact design, it is proposed to arrange the motor offset from the central plane on the other side. It is preferred if the motor is arranged closer to the rocker axis than the eccentric.

According to a preferred embodiment, the power transmission chain comprises at least one acting on the rocker lifting device by which an up-down movement, which is preferably derived by the eccentric from the rotational movement of the motor, is easily transferable to the rocker.

According to the invention, in particular, a training device for the stimulation and training of the musculoskeletal system of a person with at least one motor which drives a lifting device, by which a rocker carrying the person about a rocker axis is set in pivotal movement, according to the invention only a lifting device one side of the rocker axis is provided.

The fact that the training device is provided only on one side with a lifting device for the rocker, no vote multiple lifts is necessary. The device is simpler in construction, lighter and less expensive.

According to a second alternative development of the invention, it is proposed that the force transmission chain in the rocker axis is rigidly connected to a rocker shaft rotatably connected to the rocker and defining the rocker axis or to the rocker.

While two lifting devices are provided for driving the rocker in the prior art, this alternative development allows a slightly different way constructively compared with the first alternative training with a rotary drive for the rocker, which acts on this in the region of their rocker axis to their oscillating oscillatory motion produce. This type of introduction of the driving force in the rocker is thus fundamentally different from that of the prior art. In addition, the drive according to the invention can be realized in different ways easily and inexpensively.

In this context, it is preferred that as a rigidly connected transmission element of the power transmission chain is provided at an angle, preferably orthogonal from a bottom of the rocker downwardly extending lever or crank member which is hingedly connected to another transmission element, in particular a pusher ,

According to the invention, in particular, a training device for the stimulation and training of the musculoskeletal system of a person with at least one motor and a person supporting rocker, wherein the rocker is about a rocker axis in Schwenkbewegung.versetzbar via a motor actuated by the motor and in which According to the invention, the drive causes the rocker to rotate in the area of the rocker axis.

Such a drive is also easy and inexpensive to implement.

A preferred realization of the rotary drive is based on an eccentric, which is rotationally driven by the motor and connected to the rocker. Preferably, the eccentric is connected via a rocker arm with the rocker, which is fixed to the underside of the rocker. This training allows a minimization of the driving force by leverage. Preferably, the eccentric is connected to the rocker end with the swing lever. This can optimize the leverage of the rocker arm. The eccentric preferably comprises an eccentric disk with eccentric bolts and a power transmission rod, one end of which is rotatably connected via the eccentric pin to the eccentric disk and the other end of which is rotatably connected to the oscillating lever. This eccentric design is inexpensive and inexpensive with regard to the introduction of force from the engine to the rocker. Preferably, the eccentric disc is fixedly connected to the output shaft of the motor.

In order to have the greatest possible flexibility in achieving desired training effects, it is generally proposed that the amplitude of the pivoting movement of the rocker is adjustable, in particular in a range of 1 to 40 mm, measured on the lateral edge of the rocker parallel to the rocker axis. In this context, it is further proposed that the frequency of the pivoting movement is adjustable, in particular in a range of 3 to 70 Hz.

Preferably, a variable in its speed electric motor is used as the drive. This drives preferably via a arranged on its output shaft pulley and a belt pulley on a parallel to the output shaft axis. On this axis, preferably at least one eccentric disc is arranged, which forms the lifting device in conjunction with a hinged on the underside of the rocker arm. Preferably, however, two eccentric discs are arranged on the axis, each driving a rocker arm near the leading edge and a rocker arm near the lower edge of the rocker. This results in a more stable support of the rocker on the lifting device and a better distribution of forces. The eccentric discs and the rocker arms are preferably formed as equal parts.

The invention also includes other eccentric drives which are well known to those skilled in the drive technology art.

As already mentioned, the articulation of the lifting device is preferably provided in the outer quarter of the length of the rocker. In this case, a displaceable arrangement of the arranged on the underside of the rocker bearing can be provided, which allows you to vary the amplitude of the oscillating movement of the rocker in a simple manner. Appropriately, a radially adjustable articulation of the rocker arm can be provided on the eccentric disc for this purpose.

In order to provide a stable standing surface for the person using the training device and to absorb the forces introduced by the drive arrangement, it is proposed that the rocker pivotally mounted by means of a seesaw axis defining rocker shaft extending from this to both ends of the rocker metal plate, preferably aluminum plate, includes. A plate made of aluminum has the additional advantage that it has a comparatively low weight and is easy to work.

In order to further increase the stability and at the same time to reduce the weight of the rocker, it is preferred that the metal plate is designed with struts preferably defined by material recesses, which extend in particular at an angle, preferably orthogonal, to the rocker axis.

According to a particularly preferred embodiment of the invention, the training device has a control unit with a program memory in which different training programs with a different temporal course of the frequency and / or the amplitude of the oscillating movement of the rocker can be driven. The training device is thus suitable for a wide variety of requirements; It can be used both in the field of geriatrics for the prevention or treatment of osteoporosis or muscular atrophy, as well as recreational or competitive athletes for convalescence or targeted training and competition preparation.

In order to keep the effects of the operation of the training device on the environment as small as possible, it is proposed that the training device has a housing in which the drive assembly is accommodated, wherein the housing is mounted or storable with respect to the training device supporting soil such that the transmission of Vibrations, especially natural vibrations, the training device is damped to the ground.

In this context, it is preferred that the mounting of the housing is designed such that the housing is movable relative to the floor in a plurality of spatial directions, preferably in any spatial directions. For this purpose, it is further proposed that the housing by means of elastic bearing elements, preferably rubber-elastic and / or tubular trained bearing elements, is supported relative to the bottom. By such storage or such bearing elements vibrations of the housing containing the drive assembly can be absorbed by the storage or the bearing elements and their transmission to the ground are largely prevented.

It is further proposed that the bearing or the bearing elements between the housing, preferably a housing base plate, and a preferably non-slip supported on the floor or support base plate of the training device acts / act. Such an arrangement leads to decoupling of the vibrations of the drive assembly transmitting housing from the ground, so that by the drive assembly vibration and impact noise caused by the up / down movement of the rocker will not be transmitted as structure-borne noise to the ground. Furthermore, this opens up the possibility of optimizing the damping characteristics in terms of frequency. In this context, it is also specifically thought that the non-slip support of the base plate on the floor elastic elements, in particular rubber elements, comprises, which can be further attenuated transmitted to the base plate, by the storage or the bearing elements not fully absorbed vibrations, so that in essentially no vibration transmission to the ground occurs. As a result, the stability of the training device is increased, so that a "walking" of the training device is excluded on the floor.

In order to simplify the person using the exercise device climbing the rocker mounted on the floating housing and the descent of this and to allow the person, if necessary, a support during the rocking motion, it is preferred that on the base plate, a holding device is arranged on who can hold a person standing on the seesaw with their hands, if necessary.

Particular advantages arise when the mounting of the housing relative to the base plate and possibly to the holding device is such that the housing is capable of oscillations with at least two, preferably with three, spatial degrees of freedom relative to the base plate. This leads depending on the set rocker amplitude and rocker frequency to a certain vibration of the housing and thus the person supporting rocker in different directions in space. These vibrations are compared to the actual, driven by the motor rocker vibration, irregular, so that the person using the training device or her body can not permanently adjust to this, 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 two-dimensional, preferably Three-dimensional characterizable vibration, which is superimposed on the rocking motion, is of particular use in particular clinical pictures, such as Parkinson's, of great benefit. One could, however, also remember to give the rocker vibration by appropriate control of the engine and / or by appropriate design of the power transmission chain an irregular character.

The training device shown in Fig. 1 is composed of a housing 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 fixed such that the housing in total one forms 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 spaced therefrom an 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 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 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 each rocker arm 14, 14 'is rotatably mounted, the upper ends of which are pivotably articulated to a bearing 15 on the underside of a rocker 16.

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 pulley 7, the axle 6, the two eccentrics 11, 12 and the rocking levers 14, 14 'designed as push rods is. The power transmission is divided on the axis 6 on the two eccentrics 11, 12 and the two rocker arms 14, 14 '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 rocker 16 is in its center on its underside by means of a Rocker shaft 23 defining rocker shaft 30 is mounted, which is mounted in a respective fixed to the front wall 20 and on 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 to the side walls 21 and 22 and the front wall 20 and the rear wall 19 has so much game in that it can perform an oscillating oscillating or pivotal movement about its rocker axis 23. However, the gaps between the side edge of the rocker 16 and the walls 19, 20, 21 and 22 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 center of the axis 6. It also depends on the length of the rocker arm 14 and of the position of the bearing 15. 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 with unchanged use coming eccentrics, the bearings 15 in the direction orthogonal to the rocker axis slidably attached to the rocker. Such a releasable attachment could for example be achieved by engageable complementary profiles, for example in the sense of detents or the like, on the bearings and the rocker. Here, the profiles for safe fixing of the bearing 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, for the purpose of setting the amplitude and combinations of the above Adjustment options on the various gear 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 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 are arranged for the axis 6 and the bearings 15 on the underside of the rocker 16 preferably 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 may be provided with balancing weights to avoid unwanted vibrations on the 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 with respect to the forces acting as an aluminum plate having not shown on its underside in the embodiment 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 different temporal course of the frequency and / or the amplitude of the oscillating oscillatory movement of the rocker 16 is stored and depending on Demand are available. 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 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 shown schematically in Fig. 4, the training device comprises an open-topped housing with a base plate 1, on the two side walls 21 and 22 and two front and front, not shown Rear walls are attached. 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 rotatably mounted in its longitudinal center by means of a rocker axis 23 in pivot bearings in the front and rear walls, not shown, and is offset by a drive described below in an oscillating oscillation about the rocker axis 5. 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 rocker axis 23 for rotational force introduction into the rocker 16. Alternatively, the eccentric with the rotatably connected to the rocker 16 rocker shaft 23 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 axis 23 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 rocking lever 28 is fixedly connected to the underside of the rocker 16 in the area of the rocker axis 23. 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 rotatably connected to 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 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, 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 rotational movement of the electric motor 2 causes the eccentric 26 in rotation, the eccentric pin 27 entrains the end of the power transmission rod 29 articulated thereto, the rotational movement of which is transmitted to the lower end of the rocker arm 28. 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.

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.

In the figure 5, the housing of the training device, in particular its front wall 20 and the base plate 1, shown schematically. The accommodated in the housing drive assembly may be formed according to one of the two 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 corresponding feet 36 on the Floor 38 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.

At the connector 44, for example, an unillustrated screen, in particular touch screen, or another interface device may be attached, which is connected to the control unit 24 shown in Figure 1 and allows the adjustment of the controller 24 by the person standing on the rocker. Of course, the rods 42 and the connecting piece 44 may also be integrally formed with each other be. 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.
