Description

The invention relates to a device for transmitting stimulating mechanical impulses to the body of a user.

Devices are already known of the type mentioned, which should transmit stimulating mechanical impulses to the body of a user. The previously known devices have a motor rotatably driven Exenterwelle with adjustable amplitude, wherein the non-circular motion of the eccentric shaft is transmitted as stimulating impulse to the body of the user. With such devices a stimulation is aimed at mechanical whole body vibrations. The complex nature of the vibrations is decisive, which results in effects on physiological levels. Whereas in everyday life the movement sequences before the training are characterized by a coarse structure, randomized stimulation leads to an improved interaction between the central and peripheral nervous system and thus to more efficient rounder movement sequences. If nerves and muscles are stressed with high variable stimulus sequences, the organism constantly reacts to the altered stimuli. On the basis of these mechanical oscillations and impulses, physiological movement patterns and abilities can be improved. Improved processes in the body on numerous levels, for example receptor stimulation, reflex release or improved or enhanced brain activities, are aimed at.

The prior art devices are structurally complex and therefore also in need of improvement.

It is therefore an object to provide a device of the type mentioned, which is structurally simple and can be produced with little effort, and which is characterized by a more efficient transmission of stimulating mechanical impulses to the body of the user.

The achievement of this object is the features of the current claim 1.

The device according to the invention has at least one base plate, which is held movably in the longitudinal and / or transverse direction. On the underside of the plate plate at least one hammer is movably mounted, which strikes upon movement of the base plate on the underside of the plate. This percussion hammer converts the movements of the user standing on the at least one footplate into blows on the underside of the plate and thus into mechanical impulses which the user can feel as mechanical stimuli and if necessary also hear.

The desired effect of the device according to the invention is further improved if the device has two foot plates, which are preferably kept independently movable and each having at least one movably mounted percussion hammer on its underside of the plate. Does the device have two? independently movably mounted foot plates, which each have at least one movably mounted percussion hammer on its underside of the plate, can be transmitted to the user's body independently of one another via the one footplate and the other footplate, independently of one another.

In order to make the movement pattern of the user standing on the at least one footplate as varied as possible, and in order to transfer the most complex, randomly acting vibration patterns to the user's body, it is advantageous if the at least one footplate is movably suspended from the device and if the at least a foot plate is preferably suspended by means of cables or chains movable.

The at least one footplate can be moved particularly well in approximately one plane of movement if the at least one footplate is rectangular and if in the corner regions of the at least one footplate in each case at least one chain or a rope acts.

A preferred embodiment according to the invention provides that at least one, on the underside of the plate at least one base plate movably mounted percussion hammer is designed as a two-armed lever which abuts with the arm end of its one lever arm on the underside of the plate.

In order to be able to convert a movement of the at least one footplate into mechanical stimuli with the aid of the at least one percussion hammer, it is advantageous if a lever arm which projects preferably approximately at right angles over the underside of the panel carries a weight or is designed as a weight. A stimulus transmission to the user and a transmission of a blow of the percussion hammer on the underside of the plate vibrations generated is favored when the abutting on the underside of a foot plate arm end is angled towards the underside of the plate.

In order to transfer as many as possible randomly sequential stimuli to the user during the training, it is advantageous if two or more percussion hammers are movably mounted on the underside of one foot plate and if at least one percussion hammer is deviating from the other percussion hammers.

In order to facilitate the handling of the device according to the invention and to provide the user with the greatest possible comfort, a preferred embodiment according to the invention provides that for the movement of at least one base plate it is in drive connection with a motorized eccentric drive.

The eccentric drive can attack with its eccentric directly to at least one of the foot plates. However, preference is given to an embodiment in which the eccentric drive is connected at least to one foot plate via at least one of the ropes or chains intended for the movable suspension of this foot plate and / or the at least one cable or the at least one chain with its end region facing away from the foot plate at one Eccentric cam of the eccentric is held.

In order to implement the eccentric movement of the eccentric drive in corresponding pulses on the device according to the invention, it is advantageous if the eccentric drive has a drive shaft with at least two spaced-apart eccentrics, and if each of the eccentric one of each of the movable suspension of this foot plate certain ropes or Chains is held.

The pulses generated by means of the eccentric drive can be transmitted to the footplates in a particularly effective manner if the eccentrics provided on the drive shaft are preferably offset diametrically in the circumferential direction of the shaft. In this embodiment, the corresponding foot plate is alternately raised or lowered by the one or the other eccentric of the eccentric drive, whereby the on the underside of the plate base movably mounted percussion hammer can strike on the underside of the plate.

A preferred embodiment according to the invention, by means of which the desired mechanical impulses can be transmitted to the user without jeopardizing the firmness of the user on the foot plates, provides that on a narrow side of the foot plate and in particular on the heel-side narrow side the footplate provided ropes or chains are in drive connection with the drive shaft.

Further developments according to the invention will become apparent from the following description taken in conjunction with the claims and the drawings. The invention will be explained in more detail with reference to a preferred embodiment.

In the Fig. 1 to 5 and FIGS. 6 to 7 show two embodiments of a device 1, which device 1 is provided for transmitting stimulating mechanical impulses to the body of a user. The device 1 has a device stand 2, which can be placed on the floor 3 immovable.

The device 1 has at least one base plate 4, 5 and preferably two base plates 4, 5, which are held movable in the longitudinal and / or transverse direction. In order to keep the at least one base plate 4, 5 preferably movable on all sides, is the at least one foot plate 4, 5 on the device 1 preferably suspended by means of cables or chains 6 movable.

From a comparison of Fig. 1 to 3 and 6 to 7 It is clear that the at least one base plate 4, 5 is formed at right angles and that in the corner regions of the at least one base plate 4, 5 each a rope or - as here - a chain 6 attacks.

On the plate bottoms 7 of the foot plates 4, 5 are one, two or preferably several percussion hammer 8 held movable.

The on the underside of the plate 7 of the foot plates 4, 5 movably held percussion hammer 8 strike at a movement of the base plate 4, 5 on the underside of the plate 7. These percussion hammer 8 thus translate the movements of the user standing on the at least one footplate 4, 5 into beats on the underside of the plate 7 and thus into mechanical impulses which the user can feel as mechanical stimuli and optionally also hear.

The provided for the right and left foot of the user foot plates 4, 5 are suspended from the device stand 2 of the device 1 movable. The foot plates 4, 5, for example, in the Fig. 1 to 5 shown device 1 by the legs of the user horizontally forward and backward alternately in slow and fast sequence of the legs moves. Due to the loose or floating suspension, the foot plates 4, 5 move horizontally in the x- / y-axis. Under each foot plate, the percussion hammer 8 are mounted. During exercise, the user can hold and support at least one handle and preferably two handles 20 of the implement stand.

In the Fig. 1 to 7 It can be seen that each percussion hammer 8 is designed as a two-armed lever which abuts with the arm end 9 of its one lever arm 10 on the underside of the plate 7. While a preferably at rest about the plate bottom 7 protruding approximately right lever arm 10 carries a weight 11, which is on the underside 7 of a foot plate 4, 5 abutting arm end 9 is angled towards the plate bottom 7 out.

In the Fig. 1 to 7 It can be seen that on the underside of the plate 7 several, here for example three percussion hammer 8 are movably mounted, wherein at least one percussion hammer 8 should be deviating from the remaining percussion hammers 8 of this base plate 4, 5 formed. The percussion hammer 8 at least one foot plate 4, 5, for example, have different lengths of lever arms 10 and / or different weights 11, so that the percussion hammer 8 implement the movement of their associated foot plate 4, 5 different in noticeable blows on the underside of the plate.

While at the in the Fig. 1 to 5 Device shown embodiment, the movement of the foot plates 4, 5 is generated by a shift of weight of the user and / or by a movement of his feet by the user himself is in the in the Fig. 6 and 7 illustrated device version of the device 1 a motorized Fußplattenantrieb provided. This Fußplattenantrieb has a motor eccentric 21, which is for driving at least one base plate 4, 5 with this in drive connection. The eccentric drive 21 is at least connected to a foot plate 4, 5 via at least one of the movable suspension of this foot plate 4, 5 specific chains 6.

In the embodiment shown here according to the Fig. 6 and 7 are both, on a narrow side of the base plate 4, 5 and preferably provided on the heel side narrow side of the base plate 4, 5 chains 6 with the drive shaft 22 of the eccentric 21 in drive connection. The eccentric drive 21 has a rotatably mounted drive shaft 22 which has two spaced-apart eccentric 23, 24. At each of these eccentrics 23, 24 each one of the movable suspension of the foot plate 4, 5 specific chains 6 is held.

Out Fig. 7 It can be seen that the provided on the drive shaft 22 eccentric 23, 24 offset in the circumferential direction of the drive shaft 22 and in particular diametrically, that are offset by 180 °. The eccentric 21 causes the provided on a narrow side of the base plate 4, 5 plate corner areas are alternately alternately raised and lowered.

The foot plates 4, 5 of the device 1 according to Fig. 6 and 7 may be assigned a common eccentric 21, the two foot plates 4, 5 to move in motion and in particular to raise or lower alternately. However, preference is given to the here in the Fig. 6 and 7 illustrated embodiment in which each foot plate 4, 5 is associated with an eccentric 21 each. The eccentric drives 21 have a preferably electric drive motor 25 which is in drive connection with the drive shaft 22 via a gearbox 26 designed as a toothed belt drive. By alternately lifting the foot plates 4, 5 by means of the eccentric drive of the foot plates 4, 5 desired wobble effect is favored and extended. The here on the heel-side corner regions of the foot plates 4, 5 attacking and with the eccentrics 23, 24 in drive connection Chains 6 cause the lifting of the foot plates 4, 5 at its heel-side end face about the rotation axis C, which is arranged approximately in the region of the toe-side narrow side of the foot plates 4, 5. The wobbling movements of the Fußplätten 4, 5 are favored by the mounted on the plate bottoms 7 percussion hammer 8 even more. By using an eccentric drive, which has an eccentric or, as here, also several eccentrics, in conjunction with hammer hammers 8 of different weights, the conditions for the targeted metering of the chaotic movement of the foot plates 4, 5 can be created.
From a comparison of Fig. 6 and 7 It becomes clear that the tumbling movements generated by the footplate drive represent a more or less subtle movement in principle around all axes. In Fig. 7 is indicated by dashed lines that move with the help of Fußplattenantriebs foot plates 4, 5 - querab to the user - perform in the area D, among other things, horizontal movements.

Due to the different length of the lever arms 12, the percussion hammers 8 in the forward or backward movement of the foot plates 4, 5 in time sequence never equal to the bottom plate 7 of the base plate 4, 5 in the vertical direction. By the same motion pattern of the foot plates 4, 5, by the unequal load of the feet of the user on the base plates 4, 5 of the device 1 and by the inertia of the foot plate 4, 5 and the suspended from her percussion hammer 8 system do not work predictable impulses to the human body of the user. The vibration stimuli exerted on the body of the user with the aid of the device 1 are particularly suitable for the rehabilitation of patients whose strength and mobility is limited or whose coordination ability is weakened. The standing on the base plates 4, 5 users can Foot plates 4, 5 deliberately put in forward and backward movements. These irregular impulses and signals are perceived by the user's brain, which initiate positive processes in the user's organism. This neurotrophins, that is, body-own signaling substances released that cause a targeted connection between the nerve cells and ensure the survival of neuronal connections. With the help of the device embodiments of the device 1 shown here, the nerves of the user are to be stimulated, the vibrations generated by the percussion hammer 8 on the underside of the plate 7 of the foot plates 4, 5 generate a signal of low energy. Depending on the design of the percussion hammer 8 and / or the underside of the plate 7 of the foot plates 4, 5 every beat of the percussion hammer 8 on the underside of the plate 7 is good or less audible, with well audible beating and an increased stimulus can be generated.
