Description

The invention relates to a vibration device for training and therapeutic applications according to the preamble of claim 1. The vibrating device comprises a frame, on which a first floor element for placing a foot and a second floor element for placing another foot are provided. The two floor elements are movably held on the frame via a first and second bearing assembly. In this case, both the first bearing arrangement on the first floor element and the second bearing arrangement on the second floor element each have three bearing devices each having at least two degrees of freedom. In addition, a movement mechanism driven by a motor is provided, by means of which a recurring pivoting movement can be generated via the bearing arrangements on both floor surface elements, in each case both about a longitudinal axis and about a transverse axis.

Such vibration devices are used for medical or physiotherapeutic applications or for training purposes, in which in particular the muscles of the user should be stimulated and built up and / or the sense of balance should be improved. For this purpose, the user turns to the stand surface elements that are vibrating or wobbling moved during operation on the movement mechanics, so that the movements are delivered to the feet of the user. The muscular apparatus and the equilibrium organs of the user react to the movements generated by the vibrating device to compensate for them and thus maintain the upright posture.

Out EP1447071B1 For example, a vibration device is known in which two base elements can each be moved about a longitudinal axis and a transverse axis. The two stand surface elements are mounted on mutually adjacent inner sides of a respective ball joint and on a respectively remote from the inside outside via two pairs arranged connecting rod means. In this case, the connecting rod devices are each driven offset relative to one another via an eccentric shaft, in order to generate a wobbling vibration movement on both surface-area elements.

A disadvantage of the known vibration device is that a relatively complex movement mechanism with a double chain or belt drive is required due to the relatively widely spaced eccentric shafts of the two floor elements. This movement mechanism causes relatively high production costs and is also prone to failure or maintenance.

The object of the invention is to avoid the disadvantages mentioned in a generic vibration device and to allow a cost-effective production and a stable and cost-effective operation.

This object is achieved by a vibration device having the features of claim 1. In this case, the first bearing arrangement has a first bearing pair of two bearing devices and the second bearing assembly has a second bearing pair of two bearing devices on each of a first side of the base elements. Here, all four storage facilities of the two bearing pairs are mounted coaxially on the first side along a common axis and can be acted upon by the motor with a driving force. As a result, both footprint elements can be particularly easily driven by a common motor, whereby the manufacturing cost of the movement mechanism and the vibration device can be reduced overall. In addition, a low-maintenance and stable operation can be ensured by the simple structure of the movement mechanism.

It is advantageous if the common axis is formed by a common drive shaft. This makes it possible to apply all four storage facilities simultaneously via the common drive shaft with the torque generated by the engine to generate a staggering motion or vibration on the floor surface elements.

Advantageously, the four storage facilities each have a connecting rod, which is mounted eccentrically on the drive shaft. As a result, a stable transmission of movement is ensured by the drive shaft to the storage facilities and of these on the floor space elements.

Moreover, it is favorable if the connecting rod has a connecting rod eye on a shaft-side end, which cooperates with an eccentric disk of the drive shaft. By this arrangement, the rotational movement of the drive shaft can be converted into a stable longitudinal movement of the connecting rods, which in turn can be used for recurring deflection of the respective floor element. By appropriate dimensioning of the eccentricity of the eccentric disk while a desired amplitude of the recurrent lifting and lowering movement of the stand surface elements can be adjusted during operation of the vibrating device.

Advantageously, the storage facilities of the first pair of bearings and the storage facilities of the second pair of bearings are each offset from each other in the direction of rotation offset by a bearing offset eccentrically on the drive shaft. Through this bearing offset, the two storage devices each generate a pair of bearings each offset staggered lifting and lowering movements, which leads to a tumbling motion of both floor elements both about the longitudinal axis and about the transverse axis. In this way, the muscles and the sense of balance of the user can be stimulated in a particularly effective manner.

It is advantageous if the bearing offset 10 to 30 °, whereby the excitation of the muscles and the sense of balance takes place in a gentle manner.

Furthermore, it is advantageous if the bearing devices of the two pairs of bearings are offset from each other in the direction of rotation by a bearing pair offset offset eccentrically on the drive shaft. In this way, mutually offset tumbling movements are generated at the two footprint elements, which can further increase the excitation of the musculature and the sense of balance of the user.

Advantageously, the bearing pair offset is adjustable, such as by an adjustable within a connecting rod eye eccentric. In this way, the vibration device or the vibration behavior of the two floor elements to each other depending on the purpose and user can be set individually.

Furthermore, it is favorable if the bearing pair offset can be changed automatically, whereby the oscillation behavior of the two surface elements changes over a period of application of the vibrating device to each other in order to counteract a habituation effect of the user, especially in longer applications.

In a further advantageous embodiment, the bearing devices of the two bearing pairs in this case an offset from each other 10 up to 30 °. In this area, an effective stimulation of the muscles can be achieved, while the user can maintain a sufficiently stable state.

It is advantageous if the four storage facilities have a ball joint on a stand-side end of the respective connecting rod on which the respective floor element is rotatably mounted. As a result, the connection between the connecting rods and the stand surface elements on three degrees of freedom, whereby a trouble-free motion transmission can be ensured by the connecting rods on the floor elements.

Advantageously, both the first stand surface element and the second stand surface element is held on a side facing away from the first side second side via a ball bearing on the frame, whereby a particularly flexible mounting of the stand surface elements is achieved during operation.

In a particularly advantageous embodiment, the ball bearing is in this case rigidly connected to the frame on one side, so that only rotational movements and in particular no translational movements occur at this. In this way, an area with an amplitude of approximately zero is held on the ball bearings. In this way, a user, for example, at the beginning of an application, initially on the second side in the area of low amplitude on the stand surface elements. Once he has a firm stance, he can then move his feet toward the first side of the floor elements to expose his body to an increasingly greater amplitude. The envisaged ball bearings thus produce on the second side a zone of greater stability, which can be used by the user for easier entry or for an intermediate recovery from the tumbling movement.

It should be noted that all features described above of the article according to the invention are interchangeable or combinable, provided that an exchange or a combination of the same is not excluded for technical reasons.

The 1 and 2 show a vibrating device 2 for generating recurring pivoting movements or tumbling movements on a first floor element 4 and a second floor surface element 6 , On this a user can get his feet F Put on to his muscles and his organs of balance by the movement of the vibratory device 2 for exercise or therapeutic purposes.

The first floor element 4 is here via a first bearing arrangement 8th and the second floor surface element 6 via a second bearing arrangement 10 on a rack 12 kept, which can be parked on a floor.

Both bearing arrangements 8th . 10 each have three storage facilities L on. Two of the three storage facilities L form a first pair of bearings 14 and a second bearing pair 16 on a first page S1 the two floor space elements 4 , 6. The respective third storage facility L also forms a first ball bearing 18 or a second ball bearing 20 on one of the first page S1 remote second side S2 of the respective floor element 4 . 6 is provided.

Both ball bearings 18 . 20 on the second page S2 connect the respective floor surface element 4 , 6 directly with the frame 12 , wherein a rigid connection of one side of the ball bearing 18 . 20 with the frame 12 and a likewise rigid connection of another side of the ball bearing 18 . 20 with the respective floor element 4 . 6 is trained. In this way, during operation of the vibrating device 2 the amplitude at the ball bearing 18 . 20 towards zero.

The two bearing pairs 14 and 16 are part of a movement mechanic that comes from a motor 22 is drivable and by means of the two floor elements 4 . 6 can be placed in the desired tumbling motion in which this is both about a transverse axis AQ as well as about a respective longitudinal axis AL around are pivotally recurring. Both the transverse axis AQ as well as the two longitudinal axes AL extend through the ball bearings 18 . 20 extend.

As in particular from 3A it can be seen, have the storage facilities L the two bearing pairs 14 . 16 in each case a connecting rod 24 on, at a wave-side end a connecting rod eye 26 forms, with an eccentric disc 28 interacts. The four eccentric discs 28 are here with a drive shaft 30 connected by the engine 22 is driven, how out 1 can be seen. This forms the drive shaft 30 an axis A at the four storage facilities L the two bearing pairs 14 . 16 are stored together and coaxial and about which they with a driving force or with a drive torque M the motor can be acted upon.

At a stand-side end of the connecting rods 24 are each ball bearings 32 provided that in operation by their three degrees of freedom an undisturbed tumbling motion between the floor elements 4 . 6 and the movement mechanics of the vibration device 2 enable.

How out 3A it can also be seen, the storage facilities L the two bearing pairs 14 . 16 each with a bearing offset, for example, between 10 and 30 ° and by the two floor elements 4 . 6 the connecting rod 24 each left storage facility L in the time shown is deflected higher than the connecting rod 24 the respective right storage facility. Due to this bearing offset between the storage facilities L both bearing pairs 14 . 16 When driving the movement mechanism is a recurring pivotal movement of the two floor elements 4 . 6 around the respective longitudinal axis AL generated. Here are the two floor space elements 4 . 6 in the embodiment according to 3A arranged parallel to each other at all times.

Alternatively, it is possible that also the first pair of bearings 14 opposite the second bearing pair 16 a total bearing pair offset in the direction of rotation D around the axis A having. As a result, the two floor space elements 4 . 6 , as in 3 B illustrated during operation of the vibrating device 2 pivoted offset to each other. In this way, the reactions to be provided by the musculature and the equilibrium organs of the user can compensate for the vibratory or tumbling movements of the two standing surface elements 4 . 6 be further increased, whereby the training effect can be increased.

Here, for example, an adjustability of the bearing pair offset can be provided, such as by an adjustable relative to the connecting rod eccentric disc 28 (not shown). In this way, the intensity of the user-compensated movement of the vibrating device 2 depending on the purpose and user can be set individually. In this case, it is also possible to change the bearing pair offset automatically during an application, such as by an electric actuator on the adjustable eccentric disc 28 operating according to a given control profile or at random (not shown). In this way, especially during prolonged use or more frequent use of the vibration device by the same user a habituation effect can be prevented by which the training effect or the muscle could be reduced.

In a further alternative embodiment of the vibration device 2 according to the in 3C displayed time during an application is the first pair of bearings 14 opposite the second bearing pair 16 arranged in mirror image. In this way, both floor elements move 4 . 6 during operation of the vibratory device 2 exactly opposite.

Regardless of the orientation of the two bearing pairs 14 . 16 each other occurs on the first page 1 the two floor space elements 4 . 6 in the operation of the vibrating device in each case a maximum amplitude, while at the in the 1 and 2 illustrated second page S2 at the ball bearings 18 . 20 the amplitude is zero.

The user thereby has the option of an application, for example by placing the feet on the second side S2 To start his muscles and his sense of balance initially only a lower amplitude suspend. By shifting his feet F towards the first page S1 He can then automatically increase the intensity of the application depending on his own feelings.

It should be noted that all the above-described elements and features of the various embodiments of the subject invention are interchangeable or combinable with each other, provided that an exchange or a combination thereof for technical reasons is not excluded.
