Definitions
- the invention relates to a training device according to the preamble of réelle1.
- Such a training device is from the DE 199 44 456 A1 known.
- Another training device is from the EP 0 929 284 B1 known.
- 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.
- 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.
- 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.
- 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.
- An elastic connection of the gear element on the rocker or on a fixedly connected to the rocker lever element dampens in an advantageous manner at the bottom or top dead center of the pivotal movement occurring shocks or blows.
- the rocker can be operated joint-friendly.
- the elastic connection is such that the transmission element has at least two different elastic degrees of freedom of movement relative to the rocker or to the lever element.
- the elastic connection is such that the transmission element has at least one elastic Schenkambas mecanicsgrad relative to the rocker or the lever element.
- 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 over the power transmission chain issued pivotal movement, in particular at the movement direction reversal points.
- 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.
- 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.
- a particularly effective damping effect can be achieved.
- Such a bracket 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 the main component the pivoting movement and other components in different spatial directions, especially a translational movement component of the rocker in the deflection of the leaf spring element arrangement has an advantageous effect on a training effect of the person using the rocker, since the body of the person does not a regularly repeating pattern of movement can be set, as is the case for example with the rocker device known from the prior art.
- 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 Operaschwenkambaen the rocker be performed. Under certain circumstances, no effective pivot axis can be identified, but the pivoting movement results solely from a spatially distributed deflectionNerbiegung the leaf spring element arrangement addressed here.
- the elastic support of the rocker is such that the rocker has at least three different degrees of elastic freedom of movement relative to the rocker stand.
- the elastic posture is such that the rocker has at least one degree of elastic freedom of movement relative to the rocker Rocker stand has.
- a wear-prone and costly pivot bearing can be replaced by a structurally very simple measure, as already mentioned.
- 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 order to facilitate a translatory rocker movement superimposed on the pivoting movement of the rocker.
- 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 exercising person, etc. This results in undefined vibrations and additional movements, which are superimposed on the lifting movement or the pivoting movement. 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 translatory mobility 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 moves at least approximately in a path corresponding to a horizontal path.
- a movement path of the rocker movement superimposed on the pivoting movement seems to have a particularly good therapeutic effect.
- a lying eight in eastern medicine is an important and very positive symbol that stands for strong and positive effects on the man.
- 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.
- At least one leaf spring element is provided for elastic support, which allows a relative pivoting movement between the rocker and the rocker stand and a translational mobility of the rocker in the longitudinal direction relative to the rocker stand and preferably also a mobility of the rocker relative to the rocker stand in one / the vertical direction of the training device ,
- 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.
- 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 relative to the rocker stand is effected by a deflection of the leaf spring element or at least one of a plurality of leaf spring elements, in particular bending or Torsionsausschung 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- the leaf spring element between the gear element and rocker or lever element or between rocker and rocker stand or carrier has a length of about 1.0 to 3.0 cm, preferably about 1.5 to 2.0 cm.
- the leaf spring element is designed with a material thickness of ⁇ 5.0 mm, preferably about 1.5 mm.
- the leaf spring element may be formed by a spring steel plate.
- a leaf spring element in particular made of metal
- another elastic element for example made of plastic or rubber or the like as a connection element, wherein a dimensioning of such an elastic element must be selected according to the desired operating modes of 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.
- 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.
- the eccentric is arranged directly on an output shaft of the motor.
- 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.
- the drive arrangement has at least two power transmission chains acting in push-pull on the rocker.

- This in Fig. 1 shown exercise equipment is composed of a housing serving as a rocker stand with a base plate 1 arranged in the lower region, to which a vertical front wall 20, a vertical rear wall 19 and vertical side walls 21 and 22 are fixed such that the housing has an open overall Box forms.
- 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.
- a pulley 7 is attached on the axis 6 is aligned with the pulley 4, a pulley 7 is attached.
- a belt 5 which is preferably designed as a toothed belt, but can also be formed by a V-belt or a flat belt.
- 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.
- two eccentric discs 11 and 12 are attached to the axis 6.
- an eccentric pin 13 is arranged in each case parallel to the axis 6 in alignment with one another.
- 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.
- the leaf spring elements 50 transmit the driving forces on the rocker 16, so that it is pivoted about the rocker axis 23.
- 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.
- 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.
- a drive arrangement starting from the electric motor 2, has a power transmission chain consisting of 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 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 example here thus has gear elements arranged parallel to one another which execute the same movements during operation and which belong to the same drive arrangement in the example.
- 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 about 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.
- 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.
- 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.
- 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.
- 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, on its underside in the example 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 with a in Fig. 1 indicated control unit 24 equipped with a program memory 25, in which several different training programs with a respective different temporal course of the frequency and / or the amplitude of the oscillating oscillatory movement of the rocker 16 are stored and retrievable as needed.
- control unit 24 equipped with a program memory 25, in which several different training programs with a respective different temporal course of the frequency and / or the amplitude of the oscillating oscillatory movement of the rocker 16 are stored and retrievable as needed.
- 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.

- the drive comprises an electric motor 2, which on the base plate 1 under a, in the FIG. 4 the right side of the rocker 16 is attached.
- 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.
- the eccentric with the rotatably connected to the rocker 16 rocker shaft 30 are in communication.
- 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.
- rocker arm 28 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 lower end of the rocker arm 28 comes to rest at a distance above the base plate 1.
- the power transmission chain of the transmission in the second form includes the eccentric 26 with its eccentric pin 27, the power transmission rod 29, the leaf spring element 52 and the rocker arm 28. Together with the motor 2, they form the only drive arrangement. 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 form damping of shocks is achieved by the leaf spring element 52.
- Fig. 4 In an analogous manner as in the first form can also be a training device according to the second form with a in Fig. 4 not shown, but for Fig. 1 be connected to similar control device.
- a first embodiment of the exercise device is shown, which differs from the first example in that the rocker 16 by means of at least one further leaf spring element 54 elastically held on a housing 56 of the training device, in particular the walls 19, 20 or a different stand assembly, mounted carrier 56 is.
- the carrier 56 is on the front wall 19 and the rear wall 20 (see. Fig. 2 ) and extends over the entire width of the housing.

- 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.
- leaf spring elements instead of extending in the cross-section in the vertical direction leaf spring elements also in cross-section extending in the horizontal direction leaf spring elements can be conveniently provided, especially in order to achieve a cushioning in the vertical direction particularly effective.
- the 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.

- the pivoting motion does not require a large stroke at the rocker ends to achieve a therapeutic effect.
- 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 Fig. 8 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 x 80 cm can be used for the provision of the rocker.
- Fig. 9 is particularly effective in cushioning and dampening stroke tips and reversals of movement.
- the leaf spring element 54 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.
- one or more leaf spring elements 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.
- leaf spring elements 50, 52, 54 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.

- the bearing elements 32 are secured to the base plate 1 of the housing or the base plate 34 in a suitable manner.
- 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.

Abstract
Description
Die Erfindung betrifft ein Trainingsgerät nach dem oberbegriff von Anspruch1.The invention relates to a training device according to the preamble of Anspruch1.
Ein derartiges Trainingsgerät ist aus der
Eine weiteres Trainingsgerät ist aus der
Die Wippe ist beim bekannten Trainingsgerät an gestellfesten Lagerböcken spielfrei gelagert, so dass die Wippe stets die gleichen Wippbewegungen ausführt, und zwar hin und hergehende Schwenkbewegungen um eine wohl definierte, im Raum festgelegte Schwenkachse. Es kann nur die Frequenz der Wippbewegung geändert werden, indem eine gewünschte Hubfrequenz mittels eines Steuergeräts eingestellt wird.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.
Aufgabe der Erfindung ist es, ein Trainingsgerät zu schaffen, bei dem eine gelenkschonende Krafteinleitung in die Wippe ermöglicht wird, wobei ein einfacher Aufbau mit den damit verbundenen Kosteneinsparungen bei Herstellung und Wartung berücksichtigt werden soll.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.
Diese Aufgabe wird durch ein Trainingsgerät nach Anspruch 1 gelöst,This object is achieved by a training device according to
Eine elastische Anbindung des Getriebeelements an der Wippe oder an einem mit der Wippe fest verbundenen Hebelelement dämpft in vorteilhafter Weise beim unteren bzw. oberen Totpunkt der Schwenkbewegung auftretende Stöße bzw. Schläge. Somit kann die Wippe gelenkschonender betrieben werden. Ferner kann durch eine solche elastische Anbindung auf ein kostenaufwändiges und verschleißunterliegendes Schwenklager zur Ankopplung der Kraftübertragungskette an der Wippe bzw. am Hebelelement verzichtet werden.An elastic connection of the gear element on the rocker or on a fixedly connected to the rocker lever element dampens 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.
Es wird vorgeschlagen, dass die elastische Anbindung derart ist, dass das Getriebeelement wenigstens zwei verschiedene elastische Bewegungsfreiheitsgrade relativ zur Wippe bzw. zum Hebelelement hat. Bevorzugterweise ist die elastische Anbindung derart, dass das Getriebeelement zumindest einen elastischen Schenkbewegungsfreiheitsgrad relativ zur Wippe bzw. zum Hebelelement hat.It is proposed that the elastic connection is such that the transmission element has at least two different elastic degrees of freedom of movement relative to the rocker or to the lever element. Preferably, the elastic connection is such that the transmission element has at least one elastic Schenkbewegungsfreiheitsgrad relative to the rocker or the lever element.
Betreffend die schon angesprochene Dämpfung von Stößen wird insbesondere eine derartige elastische Anbindung vorgeschlagen, dass dasConcerning the already mentioned damping of shocks, such an elastic connection is proposed in particular that the
Getriebeelement zumindest einen elastischen Bewegungsfreiheitsgrad in Kraftübertragungsrichtung hat, insbesondere zur Abfederung der der Wippe im Betrieb über die Kraftübertragungkette erteilten Schwenkbewegung, insbesondere an den Bewegungsrichtungsumkehrpunkten.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 over the power transmission chain issued pivotal movement, in particular at the movement direction reversal points.
Es ergeben sich somit sowohl Kostenvorteile als auch wesentliche Vorteile für den Benutzer, nämlich eine gelenkschonendere und dem Körper angemessenere Durchführung der Wippbewegung mit dementsprechend besonders hohem therapeutischen Nutzen.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.
Weiterbildend wird vorgeschlagen, dass zur elastischen Anbindung wenigstens ein Blattfederelement vorgesehen ist, welches eine relative Schwenkbarkeit zwischen der Wippe und dem Getriebeelement oder/und eine Abfederung der der Wippe im Betrieb erteilten Schwenkbewegung insbesondere an deren Bewegungsrichtungsumkehrpunkten ermöglicht. Dabei ist es besonders bevorzugt, dass das wenigstens eine Blattfederelement selbst ein Getriebeelement der Kraftübertragungskette ist, über welches Antriebskräfte auf die Wippe übertragbar sind.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.
Ein solches Blattfederelement weist den Vorteil auf, dass es die gewünschte elastische Lagerung und Dämpfung von Stößen ermöglicht, wobei aber eine ausreichende Stabilität gegeben ist, um die Antriebskräfte auf die Wippe übertragen zu können.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.
Nach einer besonders zweckmäßigen Weiterbildung ist vorgesehen, dass zu elastischen Anbindung wenigstens zwei in der Kraftübertragungskette hintereinander geschaltete, in verschiedene, vorzugsweise zueinander orthogonale Richtungen elastisch auslenkbare Blattfederelemente vorgesehen sind. So kann eine besonders wirkungsvolle Dämpfwirkung erzielt werden.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.
Erfindungsgemäß ist die Wippe bezüglich des Wippenständers elastisch gehalten.According to the rocker is held elastically with respect to the rocker stand.
Eine solche Halterung ist im Vergleich mit einer aus dem Stand der Technik bekanten Drehgelenklagerung konstruktiv einfacher und weniger verschleißanfällig. Ferner ergeben sich durch die elastische Halterung neben der Schwenkbewegungskomponente weitere, der Schwenkbewegungskomponente überlagerte Bewegungskomponenten, welche dazu führen, dass die Wippe kleine unregelmäßige Bewegungen durchführt. Ein solches Bewegungsmuster, das als Hauptkomponente die Schwenkbewegung und weitere Komponenten in verschiedene Raumrichtungen aufweist, vor allem auch eine translatorische Bewegungskomponente der Wippe in Auslenkrichtung der Blattfederelementanordnung wirkt sich vorteilhaft auf einen Trainingseffekt der die Wippe benutzenden Person aus, da sich der Körper der Person nicht auf ein sich regelmäßig wiederholendes Bewegungsmuster einstellen kann, wie dies beispielsweise bei der aus dem Stand der Technik bekannten Wippenvorrichtung der Fall ist. Das durch die elastische Halterung der Wippe hervorgerufene Bewegungsmuster weist auch keine eindeutig festlegbare effektive Schwenkachse auf, sondern es bilden sich im Verlauf der Bewegung gewissermaßen mehrere temporäre ortsvariable Achsen aus, um welche jeweilige temporäre Teilschwenkbewegungen der Wippe durchgeführt werden. Unter Umständen kann überhaupt keine effektive Schwenkachse identifiziert werden, sondern die Schwenkbewegung resultiert alleine aus einer räumlich verteilten AuslenkungNerbiegung der hier angesprochenen Blattfederelementanordnung.Such a bracket 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 the main component the pivoting movement and other components in different spatial directions, especially a translational movement component of the rocker in the deflection of the leaf spring element arrangement has an advantageous effect on a training effect of the person using the rocker, since the body of the person does not a regularly repeating pattern of movement can be set, as is the case for example with the rocker device known from the prior art. 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 deflectionNerbiegung the leaf spring element arrangement addressed here.
Es wird insbesondere daran gedacht, dass die elastische Halterung der Wippe derart ist, dass die Wippe wenigstens drei verschiedene elastische Bewegungsfreiheitsgrade relativ zum Wippenständer hat.It is particularly contemplated that the elastic support of the rocker is such that the rocker has at least three different degrees of elastic freedom of movement relative to the rocker stand.
Erfindungsgemäß ist die elastische Haltung derart, dass die Wippe zumindest einen elastischen Schwenkbewegungsfreiheitsgrad relativ zum Wippenständer hat. Ein verschleißanfälliges und kostenaufwendiges Schwenklager kann so durch eine konstruktiv an sich sehr einfache Maßnahme ersetzt werden, wie schon angesprochen.According to the invention, the elastic posture is such that the rocker has at least one degree of elastic freedom of movement relative to the rocker Rocker stand has. A wear-prone and costly pivot bearing can be replaced by a structurally very simple measure, as already mentioned.
Erfindungsgemäß ist die elastische Anbindung derart, dass die Wippe zumindest einen elastischen Bewegungsfreiheitsgrad in einer Längsrichtung der Wippe relativ zur Wippenständer hat, zur Emnöglichung einer der Schwenkbewegung der Wippe überlagerten translatorischen Wippenbewegung. Es resultiert so die eben angesprochene zusätzliche Bewegungskomponente, die der Schwenkbewegung überlagert ist und therapeutisch sehr vorteilhaft ist. Die Wippe bewegt sich nicht mehr streng nach einem vorgegebenen Schwenkbewegungsmuster auf und ab, sondern kann sich auch in ihrer Längsrichtung (nach rechts und links) bewegen. Diese zusätzliche Bewegung ist abhängig von verschiedenen Einflüssen, wie Gewicht, Übung und Konstitution der trainierenden Person usw. Es resultieren undefinierte Schwingungen und Zusatzbewegungen, die der Hubbewegung bzw. der Schwenkbewegung überlagert sind. Es hat sich gezeigt, dass der Körper auf ein solches Trainieren sehr stark und positiv reagiert, da ein Gewöhnungseffekt vermieden oder zumindest sehr stark reduziert wird.According to the invention, 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 order to facilitate 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 exercising person, etc. This results in undefined vibrations and additional movements, which are superimposed on the lifting movement or the pivoting movement. 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.
Besonders bevorzugt ist eine solche translatorische Beweglichkeit der Wippe relativ zum Wippenständer, dass ein Punkt an einem bei der Schwenkbewegung gemäß einem maximalen Bewegungshub sich auf und ab bewegenden Wippenende zumindest annähernd sich auf einer einer liegenden Acht entsprechenden Bahn bewegt. Eine solche Bewegungsbahn der der Schwenkbewegung überlagerten Wippenbewegung scheint eine besonders gute therapeutische Wirksamkeit zu haben. Jedenfalls ist eine liegende acht in der östlichen Medizin ein wichtiges und sehr positiv belegtes Symbol, das für starke und positive Auswirkungen auf den Meschen steht.Such a translatory mobility 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 moves at least approximately 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.
Bevorzugt ist die elastische Anbindung ferner derart, dass die Wippe zumindest einen elastischen Bewegungsfreiheitsgrad in einer Hochrichtung des Trainingsgeräts relativ zum Wippenständer hat, insbesondere zur Abfederung der der Wippe im Betrieb erteilten Schwenkbewegung insbesondere an deren Bewegungsrichtungsumkehrpunkten. Eine solche Abfederung ist gelenkschonend und unterstützt die therapeutische Wirkung, wie schon im Zusammenhang mit der elastischen Anbindung des Getriebeelements an der Wippe bzw. an dem Hebelelement angesprochen.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 mit Patienten und mit Fachleuten haben gezeigt, dass das erfindungsgemäße Gerät mit der elastischen Wippenlagerung und der elastischen Anbindung der Kraftübertragungskette sich sehr viel harmonischer und weicher anfühlt als Gerät des Stands der Technik ohne derartige Elastizitäten.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.
Erfindungsgemäß ist zur elastischen Halterung wenigstens ein Blattfederelement vorgesehen, welches eine relative Schwenkbeweglichkeit zwischen der Wippe und dem Wippenständer und eine translatorische Beweglichkeit der Wippe in deren Längsrichtung relativ zum Wippenständer und vorzugsweise auch eine Beweglichkeit der Wippe relativ zum Wippenständer in einer/der Hochrichtung des Trainingsgeräts ermöglicht.According to the invention, at least one leaf spring element is provided for elastic support, which allows a relative pivoting movement between the rocker and the rocker stand and a translational mobility of the rocker in the longitudinal direction relative to the rocker stand and preferably also a mobility of the rocker relative to the rocker stand in one / the vertical direction of the training device ,
Dabei ist es besonders bevorzugt, dass das wenigstens eine Blattfederelement wippenseitig und ständerseitig festgehalten ist und die Schwenkbeweglichkeit der Wippe relativ zum Wippenständer durch eine Biege- oder Torsionsauslenkung des Blattfederelements erfolgt. Demgegenüber verallgemeinert wird vorgeschlagen, dass das wenigstens eine Blattfederelement wippenseitig oder/und ständerseitig festgehalten ist und die Schwenkbeweglichkeit oder/und die translatorische Beweglichkeit oder/und die Beweglichkeit in Hochrichtung der Wippe relativ zum Wippenständer durch eine Auslenkung des Blattfederelements oder wenigstens eines mehrerer Blattfederelemente erfolgt, insbesondere Biege-oder Torsionsauslenkung des Blattfederelements bzw. jeweiligen Blattfederelements betreffend die Schwenkbeweglichkeit und insbesondere Biegeauslenkung des Blattfederelements bzw. jeweiligen Blattfederelements betreffend die translatorische Beweglichkeit bzw. die Beweglichkeit in Hochrichtung.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 relative to the rocker stand is effected 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.
Besonders zweckmäßig können zur elastischen Halterung wenigstens zwei hintereinander geschaltete, in verschiedene, vorzugsweise zueinander orthogonale Richtungen elastisch auslenkbare Blattfederelemente vorgesehen sein, so dass einerseits eine besonders gute Dämpfung und andererseits eine ausgeprägte, der Schwenkbewegung überlagerte zusätzliche Beweglichkeit erreicht wird.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.
Da die Biege- oder Torsionsauslenkung abhängig von den Dimensionen und Materialeigenschaften des Blattfederelements sowie abhängig von der auf die Wippe wirkenden Belastungen veränderlich ist, führen bereits kleine Veränderungen der Fußstellung der Person oder/und Veränderungen in der Hubhöhe bzw. Hubfrequenz der Wippe zu einem veränderten Bewegungsmuster, so dass die oben bereits beschriebenen Vorteile besonders wirkungsvoll erreicht werden. Anzumerken ist aber, dass auch andere Federelemente in Frage kommen, um entsprechende Vorteile und Wirkungen zu erreichen.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.
Um die elastische Halterung der Wippe zu ermöglichen, wird vorgeschlagen, dass der Wippenständer mit einem sich quer zur Wippe unterhalb dieser erstreckenden Träger ausgeführt ist, wobei es bevorzugt ist, dass entlang des Trägers ein einziges Blattfederelement oder mehrere ineinander gesonderte Blattfederelemente in der Wippenunterseite und im Träger eingespannt ist/sind. Der Träger kann starr an einer Ständeranordnung des Wippenständers gehalten sein und insoweit als Teil des Wippenständers angesehen werden.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.
Gemäß einer zweckmäßigen Abwandlung ist demgegenüber vorgesehen, dass die Halterung der Wippe einen sich quer zur Wippe unterhalb dieser erstreckenden Träger umfasst, der vorzugsweise elastisch an einer Ständeranordnung des Wippenständers gehalten ist. Ein solcher Träger kann als Teil der elastischen Halterung der Wippe am Wippenständer angesehen werden und beispielsweise mittels wenigstens eines vorzugsweise in Hochrichtung auslenkbaren Blattfederelements an der Ständeranordnung gehalten sein. Auch in diesem Fall ist es bevorzugt, dass entlang des Trägers ein einziges Blattfederelement oder mehrere voneinander gesonderte Blattfederelemente in der Wippenunterseite und im Träger eingespannt ist/sind. Entsprechend kann ein einziges Blattfederelement oder können mehrere gesonderte Blattfederelemente einerseits am Träger und andererseits an der Ständeranordnung eingespannt sein. Es können auch zwei auf verschiedenen Seiten des Trägers angeordnete Blattfederelemente oder zwei auf verschiedenen Seiten des Trägers angeordnete Blattfederelementgruppen vorgesehen sein.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.
Die Halterung, ggf. Einspannung des Blattfederelements bzw. des jeweiligen Blattfederelements erfolgt vorzugsweise formschlüssig mit dem Getriebeelement bzw. mit der Wippe bzw. mit dem Träger bzw. der Wippe bzw. der Ständeraordnung. Zweckmäßig kann auch eine materialschlüssige Verbindung vorgesehen sein, beispielsweise durch Verschweißung, Verklebung oder dergleichen. Eine solche Halterung ist im Vergleich mit einer Drehgelenkanordnung mit einer darin gelagerten Wippenwelle deutlich einfacher und kostengünstiger herzustellen. Ferner benötigt eine solche Halterung der Wippe und auch die bereits angesprochene elastische Anbindung des Getriebeelements an der Wippe oder an einem mit der Wippe fest verbundenen Hebelelement keine aufwändige Wartung, insbesondere keine Schmierung.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.
Das Blattfederelement für die elastische Anbindung des wenigstens einen Getriebeelements oder/und für die elastische Halterung der Wippe ist vorzugsweise aus Metall, insbesondere aus Stahl, hergestellt.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.
Dabei kann das Blattfederelement zwischen Getriebeelement und Wippe bzw. Hebelelement bzw. zwischen Wippe und Wippenständer bzw. Träger eine Länge von etwa 1,0 bis 3,0 cm, vorzugsweise etwa 1,5 bis 2,0 cm aufweisen. Bevorzugt ist das Blattfederelement mit einer Materialdicke von < 5,0 mm, vorzugsweise etwa 1,5 mm ausgeführt. Je nach Art und Ausgestaltung kann das Blattfederelement von einer Federstahlplatte gebildet sein.In this case, the leaf spring element between the gear element and rocker or lever element or between rocker and rocker stand or carrier has 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.
Selbstverständlich können die hier genannten Dimensionierungen auch für andere in Frage kommende Materialien angepasst werden, so dass eine gewünschte Halterung der Wippe bzw. Anbindung des Getriebeelements erreicht werden kann.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.
Ferner ist es auch denkbar, an Stelle eines Blattfederelements insbesondere aus Metall ein anderes elastisches Element, beispielsweise aus Kunststoff oder Gummi oder dergleichen als Anbindungs element zu verwenden, wobei eine Dimensionierung eines solchen elastischen Elements entsprechend der gewünschten Betriebsarten der Wippe ausgewählt werden muss.Further, it is also conceivable to use instead of a leaf spring element, in particular made of metal, another elastic element, for example made of plastic or rubber or the like as a connection element, wherein a dimensioning of such an elastic element must be selected according to the desired operating modes of the rocker.
Das elastisch angebundene Getriebeelement kann eine Schub-/Zugstange sein, die bezogen auf die Kraftübertragungskette an ihrem dem Motor zugewandten Ende mit einem als Exzenter ausgebildeten Getriebeelement gelenkig verbunden ist.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.
Dabei kann der Exzenter vom Motor gesondert, über eine weiteres Getriebeelement der Kraftübertragungskette, insbesondere über einen Riemen oder dergleichen, mit diesem verbunden ausgebildet sein. Eine solche Ausgestaltung ermöglicht es, den Motor und den Exzenter derart in einem Wippengehäuse unterzubringen, dass eine gute Gewichtsverteilung und eine hohe Standfestigkeit des Trainingsgeräts erreicht wird.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.
Alternativ hierzu ist es auch möglich, dass der Exzenter unmittelbar an eine Ausgangswelle des Motors angeordnet ist.Alternatively, it is also possible that the eccentric is arranged directly on an output shaft of the motor.
Weiterbildend wird ferner vorgeschlagen, dass die Antriebsanordung genau - eine Kraftübertragungskette oder mehrere derartige, zueinander parallel verlaufende und im Gleichtakt auf die Wippe wirkende Kraftübertragungsketten aufweist. Dies führt zu einem sehr einfachen und somit kostengünstigen Aufbau des Trainingsgeräts. Die parallele und in Gleichtakt auf die Wippe wirkende Anordnung mehrerer Kraftübertragungsketten weist den Vorteil auf, dass der synchrone Betrieb der verschiedenen Kraftübertragungsketten sehr einfach, insbesondere deutlich einfacher als bei bekannten gegenläufigen Kraftübertragungsketten realisierbar ist.Further, 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.
Es kommt durchaus aber auch in Betracht, dass die Antriebsanordnung wenigstens zwei im Gegentakt auf die Wippe wirkende Kraftübertragungsketten aufweist. Insoweit könnte ein Antrieb in der Art wie aus der
Bevorzugt ist vorgesehen, dass die Kraftübertragungskette bzw. die jeweilige Kraftübertragungskette eine auf die Wippe wirkende, an deren Unterseite angreifende Hubeinrichtung umfasst.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.
Durch die elastische Halterung der Wippe in Kombination mit der elastischen Anbindung des Getriebeelements kann je nach eingestellter Wippenamplitude und Wippenfrequenz eine gewisse zusätzliche Schwingung der Wippe in verschiedene Raumrichtungen erreicht werden. Diese Schwingungen sind gegenüber der eigentlichen, durch den Motor angetriebenen Wippenschwingung unregelmäßig, so dass sich die das Trainingsgerät benutzende Person bzw. ihr Körper nicht dauerhaft hierauf einstellen kann, wodurch ein Gewöhnungseffekt, wie er bei nur regelmäßigen Schwingungen zu beobachten ist, vermieden werden kann. Dies hat eine positive Auswirkung auf den Trainingseffekt. Eine solche als zweidimensional, vorzugsweise dreidimensional bezeichenbare Schwingung, welche der Wippbewegung überlagert ist, ist insbesondere bei bestimmten Krankheitsbildern, wie beispielsweise Parkinson, von hohem Nutzen.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.

Das in
An der Grundplatte 1 ist ein als Elektromotor 2 ausgebildeter Antrieb mittels mehrerer Befestigungen 3 verankert. Die Abtriebswelle des Elektromotors 2 trägt eine Riemenscheibe 4. Parallel zur Abtriebswelle des Elektromotors 2 ist beabstandet zu diesem eine Achse 6 an zwei Lagern 8 bzw. 9 gelagert. Auf der Achse 6 ist fluchtend zur Riemenscheibe 4 eine Riemenscheibe 7 befestigt. Über die Riemenscheiben 4 und 7 läuft ein Riemen 5, der vorzugsweise als Zahnriemen ausgebildet ist, aber ebenso von einem Keilriemen oder einem Flachriemen gebildet werden kann. Ersatzweise ist auch ein Antrieb mittels einer Kette, einem Seil, einem Zahnrädergetriebe, einem Kegelradgetriebe oder ähnlichem möglich, wobei bei einem Kegelradgetriebe die Abtriebswelle des Elektromotors 2 senkrecht zur Achse 6 angeordnet ist.On the
Die Lager 8 bzw. 9 sind mittels Befestigungen 10 ebenfalls an der Grundplatte 1 gelagert. Im Bereich der Lager 8 bzw. 9 sind an der Achse 6 zwei Exzenterscheiben 11 bzw. 12 befestigt. An den Exzenterscheiben 11 und 12 ist jeweils parallel zur Achse 6 fluchtend zueinander ein Exzenterbolzen 13 angeordnet. An den Exzenterbolzen 13 ist das untere Ende jeweils eines Schwinghebels 14, 14' drehbar gelagert. Die oberen Enden der beiden Schwinghebel 14, 14' sind vermittels eines jeweiligen Blattfederelements 50 mit der Wippe 16 verbunden. Dabei sind die Blattfederelemente 50 sowohl am jeweiligen Schwinghebel 14, 14' als auch an der Unterseite der Wippe 16 fest eingespannt. Wenn nun durch die Drehung der Exzenterscheiben 11, 12 die Schwinghebel 14, 14' in eine Auf-/ Abbewegung versetzt werden, übertragen die Blattfederelemente 50 die Antriebskräfte auf die Wippe 16, so dass diese um die Wippenachse 23 verschwenkt wird. Dabei dämpft das Blattfederelement durch seine elastische Auslenkung insbesondere in den Totpunkten der Exzenterbewegung auftretende Stöße, so dass diese nicht direkt und ungedämpft an die Wippe und somit die darauf stehende Person übertragen werden. Selbstverständlich sind die Blattfederelemente 50 derart dimensioniert, dass sie die wirkenden Antriebskräfte sicher auf die Wippe 16 übertragen können, so dass das Trainingsgerät zuverlässig betrieben werden kann.The
In diesem Beispiel weist eine Antriebsanordnung ausgehend vom Elektormotor 2 eine Kraftübertragungskette auf, die von der Riemenscheibe 4, dem Riemen 5, der Riemenscheibe 7, der Achse 6, den beiden Exzentern 11, 12 den als Schubstangen ausgebildeten Schwinghebeln 14, 14' sowie den Blattfederelementen 50 gebildet ist. Die Kraftübertragung wird an der Achse 6 auf die beiden Exzenter 11, 12 und die beiden Schwinghebel 14, 14' parallel aufgeteilt. Die im Beispiel einzige Kraftübertragungskette weist hier somit parallel zueinander angeordnete Getriebeelemente auf, welche im Betrieb die gleichen Bewegungen ausführen und welche zur gleichen, im Beispiel einzigen Antriebsanordnung gehören.In this example, a drive arrangement, starting from the
Die Wippe 16 ist in dieser Ausführungsform in ihrer Mitte an ihrer Unterseite mittels einer die Wippenachse 23 definierenden Wippenwelle 30 gelagert, die in jeweils einem an der Vorderwand 20 und an der Rückwand 19 des Gehäuses mittels Befestigungen 18 befestigten Lager 17 gelagert ist. Die Wippe 16 weist eine gesamte Länge L von etwa 70 Zentimetern auf. Die Länge L ist etwa geringer als der Abstand der Seitenwände 21 und 22, so dass die Wippe 16 mit der Oberkante des Gehäuses nahezu bündig angeordnet ist, jedoch zu den Seitenwänden 21 bzw. 22 und zur Vorderwand 20 und zur Rückwand 19 so viel Spiel aufweist, dass sie eine oszillierende Schwing- bzw. Schwenkbewegung um ihre Wippenachse 23 ausführen kann. Die Spalte zwischen den Seitenkanten der Wippe 16 und den Wänden 19, 20, 21 und 22 sind in jedoch so klein gehalten, dass keine Körperteile oder Gegenstände eingeklemmt werden können.The
Die Amplitude der oszillierenden Schwingbewegung der Wippe 16 hängt ab von der Größe des Abstandes des Exzenterbolzens 13 zur Mitte der Achse 6. Sie hängt auch von der Länge des Schwinghebels 14 bzw. von der Position einer Anbindung 15 der Schwinghebel an der Wippe ab. Vorzugsweise ist die Amplitude im Bereich von 1 mm bis etwa 40 mm variabel. Eines solche Variabilität der Amplitude kann beispielsweise durch einen Satz von austauschbaren Exzenterscheiben erreicht werden, deren Exzenterbolzen unterschiedliche Abstände von der Drehahse 6 aufweisen. Ferner kann bei unverändert zum Einsatz kommenden Exzentern daran gedacht werden, die Anbindung 15 in der zur Wippenachse orthogonalen Richtung verschiebbar an der Wippe zu befestigen. Eine solche lösbare Befestigung könnte beispielsweise durch miteinander in Eingriff bringbare komplementäre Profile, beispielsweise im Sinne von Rasten oder dergleichen, an den Anbindungen und der Wippe erreicht werden. Hierbei könnten die Profile zur sicheren Festsetzung der Anbindungen während des Betriebs zusätzlich noch durch eine Schraubverbindung oder dergleichen gegeneinander gedrückt und festgeklemmt werden. Schließlich wird auch daran gedacht, dass die Schwinghebel 14, 14' derart ausgebildet sind, dass sie in ihrer Länge verstellbar sind, um eine mittlere Horizontalität oder Neigung der Wippe einzustellen. Selbstverständlich sind zum bedarfsweisen Einstellen der Amplitude auch Kombinationen der genannten Verstellmöglichkeiten an den verschiedenen Getriebeelementen möglich. Die Einstellung solcher Verstellelemente kann manuell oder automatisiert, beispielsweise unter Einsatz von entsprechenden Stellgliedern, erfolgen. Selbstverständlich kann der Benutzer die Amplitude aber auch dadurch beeinflussen, dass er seine Füße mehr oder weniger weit rechts und links der Wippenachse 23 auf der Wippe 16 platziert.The amplitude of the oscillating oscillatory movement of the
Eine Verstellmöglichkeit der Schwenkamplitude unabhängig von der erwähnten Veränderung der Fußstellung auf der Wippe weist den Vorteil auf, dass der Trainingseffekt bei gleichbleibendem, insbesondere idealem bzw. für die Person bequemem Fussabstand erhöht werden kann. Ferner können durch eine von der Fußstellung unabhängige Amplitudenverstellung Extrembelastungen auf die Wippe, welche insbesondere dann auftreten, wenn eine Person ihr Gewicht durch eine sehr breite Fußstellung ganz außen auf die Wippe überträgt, vermieden werden.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.
Ferner ist vorzugsweise die Drehzahl des Elektromotors 2 variabel, so dass sich für die Frequenz der oszillierenden Bewegung der Wippe 16 ein Bereich von etwa 3 bis 70 Hz einstellen läßt. Die Drehzahländerung des Elektromotors 2 erfolgt vorzugsweise durch einen Frequenz-Umrichter.Furthermore, preferably, the rotational speed of the
Der Elektromotor 2 und die Hubvorrichtung mit der Achse 6 sind bevorzugt auf unterschiedlichen Seiten der Wippenachse 23 angeordnet. Dabei sind die Lager 8 bzw. 9 für die Achse 6 und die Lager 15 an der Unterseite der Wippe 16 vorzugsweise im äußeren Viertel der Länge L angeordnet, während der schwerere Elektromotor 2 näher an der Mitte des Gehäuses angeordnet ist. Insgesamt ergibt sich dadurch eine ausgeglichene Gewichtsverteilung, die das Tragen des Trainingsgeräts erleichtert. Die Exzenterscheiben 11 bzw. 12 oder die Achse 6 können mit Ausgleichsgewichten versehen sein, um unerwünschte Vibrationen am Gehäuse zu vermeiden. Die Wippe 16 ist als stabile Platte, gegebenenfalls mit zusätzlichen Versteifungen ausgebildet, so dass keine Schwingungen durch wechselnde Biege- Belastungen auftreten können.The
Die Wippe 16 ist im Hinblick auf die wirkenden Kräfte vorzugsweise als Aluminiumplatte ausgeführt, die auf ihrer Unterseite im Beispiel nicht dargestellte Verstrebungen aufweist. Die Ausrichtung und Dimensionierungen der Verstrebungen sind dabei so gewählt, dass die Wippe durch die einseitige parallele Krafteinleitung vermittels der beiden Schwinghebel 14, 14' keine nennenswerten Verbiegungen oder/und Verwindungen erfährt. Die Ausbildung von Verstrebungen erfolgt vorzugsweise durch Ausfräsen von Ausnehmungen in der Metallplatte, was neben der gewünschten Steifigkeit auch zu einer Gewichtsreduktion führt.The
Das Trainingsgerät ist weiterhin vorzugsweise mit einem in
Der Benutzer kann jedoch auch bei der mit einem Programmspeicher 25 ausgerüsteten Variante wie auch in einer einfacheren Variante die Frequenz und/oder die Amplitude manuell einstellen. Die Verstellung der Parameter erfolgt vorzugsweise an einem nicht dargestellten, aus dem eingangs genannten Stand der Technik bekannten Handbügel, der beispielsweise an der Vorderwand 20 befestigt ist und etwa in Brusthöhe des Benutzers hinauf reicht. Sie kann jedoch auch beispielsweise durch Drehschalter an einer Seitenwand 22 des Gehäuses erfolgen.However, the user can also manually set the frequency and / or the amplitude in the variant equipped with a

Der Antrieb umfasst einen Elektromotor 2, der an der Grundplatte 1 unter einer, in der

Ein Ende eines Schwinghebels 28 ist im Bereich der Welle 30 fest mit der Unterseite der Wippe 16 verbunden. Das andere Ende des Schwinghebels 28 ist über eine Kraftübertragungsstange 29 mit dem Exzenterbolzen 27 der Exzenterscheibe 26 verbunden. Die Kraftübertragungsstange 29 ist elastisch vermittels eines Blattfederelements 52 mit dem unteren Ende des Schwinghebels 28 und dem Exzenterbolzen 27 verbunden. Das untere Ende des Schwinghebels 28 kommt mit Abstand über der Grundplatte 1 zu liegen.One end of a
Somit umfasst die Kraftübertragungskette des Getriebes in der zweiten Form die Exzenterscheibe 26 mit ihrem Exzenterbolzen 27, die Kraftübertragungsstange 29, das Blattfederelement 52 und den Schwinghebel 28. Zusammen mit dem Motor 2 bilden sie die einzige Antriebsanordnung. Es wird darauf hingewiesen, dass auch die parallele Anordnung eines zweiten derartigen Getriebes, das entweder mit dem gleichen Motor (etwa am anderen Ende der Motorwelle) oder mit einem synchron laufenden zweiten Motor verbunden ist, denkbar ist. Hierdurch würden sich zwei Kraftübertragungsketten ergeben, die parallel zueinander verlaufen und im Gleichtakt arbeiten.Thus, the power transmission chain of the transmission in the second form includes the eccentric 26 with its eccentric pin 27, the
Eine Drehbewegung des Elektromotors 2 versetzt die Exzenterscheibe 26 in Drehung, deren Exzenterbolzen 27 das an ihm angelenkte Ende der Kraftübertragungsstange 29 mitnimmt, dessen Drehbewegung vermittels des sich elastisch verhaltenden Blattfederelements 52 auf das untere Ende des Schwinghebels 28 übertragen wird. Da das obere Ende des Schwinghebels 28 an der Wippe 16 festgelegt ist, wird die Wippe 16 um ihre Wippenachse 23 in Drehung versetzt, was zur oszillierende Schwingung bzw. Schwenkbewegung der Wippe 16 führt. Dabei wird durch das Blattfederelement 52 eine wie bei der ersten Form beschriebene Dämpfung von Stößen erreicht.A rotary movement of the
Selbstverständlich können auch bei dieser Form Verstellmöglichkeiten an den Getriebeelementen vorgesehen sein, damit die Amplitude der Schwenkbewegung einstellbar ist.Of course, can be provided to the transmission elements in this form adjustment, so that the amplitude of the pivotal movement is adjustable.
In analoger Weise wie bei der ersten Form kann auch ein Trainingsgerät gemäß der zweiten Form mit einem in

Vorteilhaft kann mittels der erfindungsgemäßen elastischen Halterung der Wippe 16 erreicht werden, dass dieser eine der eigentlichen Schwenkbewegung überlagerte translatorische Bewegung durchführt, derart, dass ein Bezugspunkt an einem Wippenende einer einer liegenden acht entsprechenden Bewegungsbahn folgt, wie in
Anzumerken ist, dass anstelle von sich im Querschnitt in Hochrichtung erstreckenden Blattfederelementen auch im Querschnitt sich in horizontaler Richtung erstreckende Blattfederelemente zweckmäßig vorgesehen sein können, speziell auch, um eine Abfederung in Hochrichtung besonders wirkungsvoll zu erreichen. Entsprechendes gilt für die elastische Anbindung des Schwinghebels an der Wippe, um den oberen und unteren Umkehrpunkt (Totpunkt) abzufedern.It should be noted that instead of extending in the cross-section in the vertical direction leaf spring elements also in cross-section extending in the horizontal direction leaf spring elements can be conveniently provided, especially in order to achieve a cushioning in the vertical direction particularly effective. The same applies to the elastic connection of the rocker arm on the rocker to cushion the upper and lower reversal point (dead center).
Es können auch mehrere hintereinander geschaltete Federelemente, insbesondere Blattfederelemente, vorgesehen sein, wie bei der sich aus
Es ist anzumerken, dass die Schwenkbewegung keinen großen Hub an den Wippenenden erfordert, um eine therapeutische Wirkung zu erzielen. So kann beispielsweise bei einer Wippe mit einer Länge von 80 cm von einem Ende zum anderen Ende ein maximaler Hub an den Enden von etwa 12 mm vorgesehen sein. Betreffend die translatorische Bewegung der Wippe kann vorgesehen sein, dass eine der Schwenkbewegung überlagerte translatorische Auslegung von etwa 2 mm auftritt, so dass im Falle der Bewegungsbahn B gemäß
Insbesondere die Ausgestaltung der
Das Blattfederelement 54 kann wie der Träger 56 durchgehend von der Vorderseite zur Rückseite ausgebildet sein, wobei es bei Einspannung im Träger 56 nicht unmittelbar mit dem Gehäuse verbunden ist. Es ist aber ebenso denkbar, dass im Träger 56 mehrere, voneinander getrennte Blattfederelemente vorgesehen sind. Eine entsprechende Ausgestaltung erfolgt auf Grund der zu erfüllenden Betriebsbedingungen bzw. Maximalbelastungen, welche beim Betrieb auf eine solche elastische Wippenhalterung wirken. In entsprechender Weise könnten die Blattfederelemente 54a ausgebildet sein.The
Neben der Anordnung eines oder mehrerer Blattfederelemente unterhalb der Wippe ist es auch denkbar, ein oder mehrere Blattfederelemente derart an der Wippe anzuordnen, dass sie auf der Vorder- bzw. Rückseite der Wippe vorstehen und mit dem Gehäuse direkt verbunden werden. Bei einer solchen Anordnung wird eine Schwenkbewegung der Wippe durch eine Torsionsauslenkung der Blattfederelemente ermöglicht, und es kann so überdies einfach eine wirkungsvolle Abfederung in Hochrichtung erreicht werden.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.
Durch die Verwendung von Blattfederelementen 50, 52, 54 gemäß den vorgestellten Ausführungsformen kann auf jeweils wenigstens eine Drehgelenk-Lageranordnung verzichtet werden, was einen vereinfachten und kostengünstigen Aufbau des Trainingsgeräts ermöglicht. Ferner reduziert sich der Wartungsaufwand, da eine Halterung bzw. Anbindung mittels eines Blattfederelements keine aneinander reibende Verschleißteile aufweist, bei denen eine Schmierung notwendig ist.By using

Da die Haltevorrichtung 40 mit der Basisplatte 34 verbunden ist, kann sich das Gehäuse und die darin gelagerte Wippe relativ zur Basisplatte 34 und der Haltevorrichtung 40 frei bewegen bzw. schwingen, insbesondere mit drei räumlichen Freiheitsgraden.On the
