Definitions

  • the invention relates to a training apparatus for the stimulation and training of the locomotor system of a person, comprising a seesaw supporting the person and pivotable with respect to a seesaw stand, and also a drive assembly with at least one motor and a transmission unit having transmission elements, wherein the transmission elements form at least one power-transmission chain between the seesaw and the motor.
  • a training apparatus of this type is known from EP 0 929 284 B1, wherein a seesaw, on which the training person stands with both legs, is driven by an electric motor which is in driving connection with two lifting devices arranged on either side of the seesaw axis.
  • the drive unit has two power-transmission chains which extend in opposition to one another from the motor disposed below the seesaw axis and operate synchronously to one another but counter-rotating, i.e. act in opposed mode on the seesaw.
  • Such a drive unit is altogether relatively complicated and is therefore expensive.
  • the seesaw is mounted without play on bearing blocks fixed to a frame so that the seesaw always carries out the same seesaw movements, i.e. reciprocating pivoting movements about a well-defined spatially located pivot axis. It is only possible to vary the frequency of the seesaw motion by setting a desired lifting frequency by means of a control device.
  • At least one transmission element is elastically connected to the seesaw or to a lever element securely connected to the seesaw.
  • Such an elastic connection damps in an advantageous manner shocks or impacts occurring at the bottom or top dead-centre position of the pivoting movement. It is thereby possible for the seesaw to be operated in a manner considerate to joints. Moreover, owing to such an elastic connection it is possible to dispense with a pivot bearing, which is both expensive and subject to wear, for coupling the power-transmission chain to the seesaw or to the lever element.
  • the elastic connection is such that the transmission element has at least two different degrees of freedom of elastic movement relative to the seesaw or to the lever element.
  • the elastic connection is such that the transmission element has at least one degree of freedom of elastic pivotal movement relative to the seesaw or to the lever element.
  • an elastic connection is proposed such that the transmission element has at least one degree of freedom of elastic movement in the power-transmission direction, in particular for the cushioning of the pivoting movement imparted to the seesaw in operation via the power-transmission chain, in particular at the movement direction reversal points.
  • At least one leaf-spring element which makes possible relative pivotability between the seesaw and the transmission element and/or a cushioning of the pivoting movement imparted to the seesaw in operation, in particular at the movement direction reversal points thereof. It is especially preferable here that at least one leaf-spring element is itself a transmission element of the power-transmission chain, via which driving forces can be transmitted to the seesaw.
  • Such a leaf-spring element has the advantage that it makes possible the desired elastic mounting and damping of shocks but in which sufficient stability is provided in order to enable the driving forces to be transmitted to the seesaw.
  • At least two leaf-spring elements are provided, which are connected in series in the power transmission chain and which can be deflected elastically in different directions which are preferably orthogonal to one another. An especially effective damping action can thus be achieved.
  • the seesaw is mounted elastically relative to the seesaw stand.
  • Such a mounting is constructionally simpler and less liable to wear compared to a pivot joint mounting known from the state of the art.
  • further movement components superimposed on the pivoting movement component are induced which have the result that the seesaw carries out small irregular movements.
  • Such a movement pattern which has as principal component the pivoting movement and further components in different spatial directions, above all preferably also a translational movement component of the seesaw in deflection direction of a leaf-spring element assembly possibly coming into consideration advantageously acts on a training effect of the person using the seesaw, since the person's body cannot adjust to a regularly repeating movement pattern, such as is the case for example in the seesaw apparatus known from the state of the art.
  • the movement pattern induced by the elastic mounting of the seesaw also does not have a clearly definable effective pivot axis but in the course of the movement to a certain extent a plurality of temporary movable axes are developed, about which respective temporary partial pivoting movements of the seesaw are carried out. In certain circumstances, no effective pivot axis can be identified at all but the pivoting movement results solely from a spatially distributed deflection/deformation of the leaf-spring element assembly under discussion here.
  • the elastic mounting of the seesaw is such that the seesaw has at least two, preferably at least three, different degrees of freedom of elastic movement relative to the seesaw stand.
  • the elastic mounting is such that the seesaw has at least one degree of freedom of elastic pivoting movement relative to the seesaw stand. Therefore, a pivot bearing which is liable to wear and is expensive can be replaced by a constructionally per se very simple measure, as already mentioned.
  • the elastic connection is such that the seesaw has at least one degree of freedom of elastic movement in a longitudinal direction of the seesaw relative to the seesaw stand, in particular so as to make possible a translational seesaw movement superimposed on the pivoting movement of the seesaw.
  • the seesaw no longer moves up and down strictly according to a predetermined pivoting movement pattern but can also move in its longitudinal direction (to the right and left).
  • This additional movement is dependent on various influences, such as weight, practice and constitution of the training person, etc. This results in undefined oscillations and additional movements which are superimposed on the lifting movement or the pivoting movement. It has been found that the body reacts very strongly and positively on such a training, since an accustomising effect is obviated or is at least reduced to a very considerable extent.
  • a translational movement of the seesaw relative to the seesaw stand such that one point on a seesaw end, which is moving up and down during the pivoting movement according to a maximum movement travel, moves at least approximately on a path corresponding to a horizontal figure of eight.
  • a movement path of the seesaw movement superimposed on the pivoting movement appears to have especially good therapeutic effectiveness.
  • a horizontal figure of eight is a significant and very positively regarded symbol which stand for powerful and positive effects on humans.
  • the elastic connection is preferred in such a way that the seesaw has at least one degree of freedom of elastic movement in a vertical direction of the training apparatus relative to the seesaw stands, in particular for cushioning the pivoting movement imparted to the seesaw in operation, in particular at its movement direction reversal points.
  • cushioning is considerate to the joints and assists the therapeutic effect, as already mentioned with respect to the elastic connection of the transmission element to the seesaw or to the lever element.
  • At least one leaf-spring element is provided which ensures a possibility of relative pivoting movement between the seesaw and the seesaw stand and/or a possibility of translational movement of the seesaw in its longitudinal direction relative to the seesaw stand and/or a possibility of movement of the seesaw relative to the seesaw stand in a/the vertical direction of the training apparatus.
  • the at least one leaf-spring element is retained on the seesaw side and on the stand side and the possibility of pivoting movement of the seesaw relative to the seesaw stand is provided by a bending or torsional deflection of the leaf-spring element.
  • the at least one leaf-spring element is retained on the seesaw side and on the stand side and the possibility of pivoting movement and/or of translational movement and/or of movement in the vertical direction of the seesaw relative to the seesaw stand is effected by a deflection of the leaf-spring element or at least one of a plurality of leaf-spring elements, in particular a bending or torsional deflection of the leaf-spring element or of the respective leaf-spring element in respect of the possibility of pivoting movement and, in particular, bending deflection of the leaf-spring element or of the respective leaf-spring element in respect of the possibility of translational movement or the possibility of movement in a vertical direction.
  • At least two series-connected leaf-spring elements can be provided which can be elastically deflected in different directions which are preferably orthogonal to one another so that, on the one hand, especially good damping and, on the other hand, a pronounced possibility of additional movement superimposed on the pivoting movement is achieved.
  • the seesaw stand is designed to have a support extending transversely to and under the seesaw, wherein it is preferable that along the support a single leaf-spring element or a plurality of mutually separate leaf-spring elements is/are clamped on the underside of the seesaw and on the support.
  • the support can be retained rigidly on a stand assembly of the seesaw stand and, to this extent, may be considered to be part of the seesaw stand.
  • the mounting of the seesaw to comprise a support which extends transversely to and under the seesaw, and which is preferably retained elastically on a stand assembly of the seesaw stand.
  • a support may be considered to be part of the elastic mounting of the seesaw on the seesaw stand and, for example, can be retained on the stand assembly by means of at least one leaf-spring element which can preferably be deflected in a vertical direction.
  • a single leaf-spring element or a plurality of separate leaf-spring elements can be clamped, on the one hand, on the support and, on the other hand, on the stand assembly. It is also possible to provide two leaf-spring elements arranged on different sides of the support or two leaf-spring element groups arranged on different sides of the support.
  • the mounting, optionally clamping, of the leaf-spring element or the respective leaf-spring element is preferably effected in a positive-engagement manner with the transmission element or with the seesaw or with the support or the seesaw or the stand assembly.
  • an adhesive or cohesive connection for example by welding, bonding or the like.
  • a mounting of this type is clearly simpler and more economical to build compared with a swivel joint arrangement with a seesaw shaft mounted therein.
  • such a mounting of the seesaw and also the already described elastic connection of the transmission element to the seesaw or to a lever element securely connected to the seesaw does not require any expensive maintenance, in particular it does not require lubrication.
  • the leaf-spring element for the elastic connection of the at least one transmission element and/or for the elastic mounting of the seesaw is preferably produced from metal, in particular from steel.
  • the leaf-spring element between the transmission element and the seesaw or lever element or between the seesaw and seesaw stand or support can in this case be of length of approximately 1.0 to 3.0 cm, preferably approximately 1.5 to 2.0 cm.
  • the leaf-spring element is designed with a material thickness of ⁇ 5.0 mm, preferably approximately 1.5 mm.
  • the leaf-spring element can be formed by a spring steel plate.
  • connection element or mounting element it is also possible to use, instead of a leaf-spring element in particular made of metal, a different elastic element, for example made of plastics material, rubber or the like as connection element or mounting element, wherein the dimensions of such an elastic element have to be chosen in accordance with the desired modes of operation of the seesaw.
  • a different elastic element for example made of plastics material, rubber or the like
  • Such an elastic element made of plastics material, rubber or the like can be provided in particular as a mounting for the seesaw on the support securely connected to the seesaw stand, since substantially static forces act on this mounting, which exhibit only small dynamic force components during the movement of the seesaw.
  • the elastically connected transmission element may be a push rod/tie rod which, with respect to the power-transmission chain, is connected in an articulated manner at its end nearest the motor to a transmission element in the form of a cam.
  • the cam can be formed separate from the motor and connected thereto via another transmission element of the power-transmission chain, in particular via a belt or the like.
  • Such a configuration makes it possible for the motor and the cam to be accommodated in a seesaw housing so that good weight distribution and a high degree of stability of the training apparatus is achieved.
  • the cam it is also possible for the cam to be arranged directly on an output shaft of the motor.

  • Rotary motion of the electric motor 2 imparts rotation to the cam disc 26 , the eccentric pin 27 of which entrains the end of the force-transmission rod 29 articulated thereto, the rotary motion of which is transmitted by means of the elastically acting leaf-spring element 52 to the lower end of the pivot lever 28 . Since the upper end of the pivot lever 28 is located on the seesaw 16 , the seesaw 16 is caused to rotate about its seesaw axis 23 , which results in the oscillating pivoting or swinging motion of the seesaw 16 . Owing to the leaf-spring element 52 , damping of shocks is achieved here as in the first embodiment.
  • a training apparatus in an analogous manner to that in the first embodiment, can be connected to a control device similar to that in FIG. 1 but not shown in FIG. 4 .
  • FIG. 5 illustrates a third embodiment of the training apparatus which differs from the first embodiment in that the seesaw 16 is retained elastically by means of at least one further leaf-spring element 54 on a support 56 attached to the housing of the training apparatus, in particular to the walls 19 , 20 or other stand assembly.
  • the support 56 is here fastened to the front wall 19 and the rear wall 20 (cf. FIG. 2 ) and extends over the entire width of the housing.
  • the leaf-spring element 54 is clamped at 58 to the upper side of the support 56 in the manner of a positive-engagement or preferably adhesive or cohesive connection.
  • An outwardly facing end of the leaf-spring element 54 is clamped at 60 in the seesaw 16 .
  • the leaf-spring element 54 is free between these two clamping zones 58 and 60 and can be deformed to the left and right with reference to FIG. 6 so that pivoting of the seesaw 16 can take place as a result of the driving force transmitted by the pivot lever 14 to the seesaw 16 .
  • no stationary pivot axis is defined here, as is the case of a pivot mounting according to the embodiment in FIG. 1 , since the extent of the deformation and the exact course of any deflection of the leaf-spring element 54 is influenced by different factors, for example such as the weight of the person standing on the seesaw, the position of the person's feet, seesaw frequency and lifting height.
  • the seesaw also does not undergo a genuine rotating movement about a pivot axis but moves to the left and right in a translational manner to a certain extent along an arcuate course corresponding to the deformation of the leaf-spring element 54 distributed spatially between the support and the seesaw.
  • the seesaw 16 carries out a translational movement superimposed on the actual pivoting motion so that a reference point at one end of the seesaw follows a movement path corresponding to a horizontal figure of eight, as indicated by the movement path B in FIG. 8 .
  • leaf-spring elements extending in a vertical direction in cross-section
  • leaf-spring elements extending in a horizontal direction, in particular also in order to achieve especially effective cushioning in a vertical direction.
  • a plurality of series-connected spring elements can be provided as in the variant of embodiment evident from FIG. 9 .
  • the pivot lever 14 is connected to the seesaw 16 via first, approximately horizontally oriented spring element 50 a , an intermediate part 14 a and a second, approximately vertically oriented leaf-spring element 50 .
  • the seesaw mounting is effected via a support 56 which is itself elastically mounted and which is retained elastically on the stand assembly 56 a via first leaf-spring elements 54 a extending approximately horizontally in cross-section.
  • a leaf-spring element 54 corresponding to the leaf-spring element 54 in FIG. 5 is operative between the support 56 and the seesaw 16 .
  • the pivoting movement does not require a large amount of travel at the seesaw ends in order to achieve a therapeutic effect.
  • a seesaw of a length of 80 cm from one end to the other end a maximum travel at the ends of approximately 12 mm can be provided.
  • the translational movement of the seesaw it is possible to provide for a translational extent of approximately 2 mm superimposed on the pivoting movement to occur so that, in the case of the movement path B according to FIG. 8 , the horizontal figure of eight has a length of approximately 2 mm.
  • the depth of the seesaw may be 40 cm for example so that a plate with dimensions of 40 ⁇ 80 cm, for example, can be used to produce the seesaw.
  • FIG. 9 is especially effective in cushioning and damping in a particularly effective manner peaks and reversals in the direction of movement.
  • the leaf-spring element 54 can be formed, like the support 1056 , continuously from the front side to the rear side, in which case upon being clamped in the support 56 it is not directly connected to the housing. However, it is also possible to provide a plurality of leaf-spring elements separate from one another in the support 56 . A corresponding configuration arises on account of the operating conditions to be satisfied or maximum loads which act on such an elastic seesaw mounting during operation.
  • the leaf-spring elements 54 could be designed accordingly.
  • one or more leaf-spring elements below the seesaw, it also possible to arrange one or more leaf-spring elements on the seesaw in such a way that they protrude on the front side or rear size of the seesaw and are directly connected to the housing. In such an arrangement a pivoting movement of the seesaw is made possible by a torsional deflection of the leaf-spring elements and, moreover, effective cushioning in a vertical direction can be simply achieved.
  • leaf-spring elements 50 , 52 , 54 By using leaf-spring elements 50 , 52 , 54 according to the above-described embodiments in each case at least one swivel joint bearing assembly can be dispensed with, which makes possible a simplified and economical construction of the training apparatus. Moreover, maintenance costs are reduced because a mounting or connection by means of a leaf-spring element does not have wearing parts rubbing against one another and in which lubrication is necessary.
  • the housing of the training apparatus in particular its front wall 20 and its base plate 1 , are illustrated schematically.
  • the drive assembly or seesaw mounting accommodated in the housing can be designed in accordance with one of the above-described embodiments and will not be described in more detail here.
  • the housing rests with its base plate 1 on four bearing elements 32 , two of which are illustrated and which themselves are supported on a base plate 34 of the training apparatus.
  • the base plate 34 is in turn supported in a slip-resistant manner by corresponding support feet 36 on the floor 38 so that the base plate 34 does not move relative to the floor 38 during seesaw operation.
  • the bearing elements 32 are secured in a suitable manner to the base plate 1 of the housing or the base plate 34 .
  • Tubular rubber parts are used as the bearing elements 32 , wherein the two rubber parts 32 illustrated are aligned differently in relation to the front wall 20 so that movements of the housing in horizontal spatial directions disposed orthogonally to one another can be uniformly accommodated.
  • the two rubber parts 32 illustrated are aligned differently in relation to the front wall 20 so that movements of the housing in horizontal spatial directions disposed orthogonally to one another can be uniformly accommodated.
  • all the rubber parts of such a mounting to be equally aligned.
  • a retaining device 40 is mounted on the base plate 34 and has two rods 42 which extend vertically upwardly from the base plate 34 and which are joined together at their upper ends via a horizontal connecting member 44 . Since the retaining device 40 is connected to the base plate 34 , the housing and the seesaw mounted therein can move or swing freely relative to the base plate 34 and the retaining device 40 , in particular with three spatial degrees of freedom.
  • the above-described mounting of the housing enables the housing and the seesaw connected thereto to swing in any spatial direction desired, wherein these oscillations have to be balanced out by the body of the person standing on the seesaw, which has a positive influence on the training effect for the person.
  • the irregularity of the oscillations induced by the mounting of the housing can be intensified in particular with an elastic mounting of the seesaw (cf. FIGS. 5 and 6 ), so that the training effect can be further assisted in an advantageous manner.
  • a visual display unit (not shown), in particular a touch screen, or other interface appliance can be attached to the connecting member 44 and is connected with the control device 24 illustrated in FIG. 1 , and makes it possible the adjustment of the control device 24 by the person standing on the seesaw.
  • the rods 42 and the connecting member 44 can also be formed in one piece with one another.
  • the retaining device 40 simplifies for the person using the training apparatus the stepping-on and off of the seesaw mounted in a floating manner relative to the floor 38 .
  • the retaining device also make possible for the person to keep a firm hold during the seesawing, in the event that he/she temporarily cannot hold the balance or if an adjustment of the seesaw frequency and/or amplitude is carried out.
