Description

The invention relates to a vibrator device according to the preamble of claim 1.

Such a vibrator device for introducing vibrations into a person comprises a carrier which is arranged and intended to make contact with that person for introducing vibrations into a person, a vibration generator which is arranged and intended to perform a vibration, wherein the vibration generator is mounted for transmitting vibrations to the carrier about a pivot axis pivotally mounted on the carrier.

The invention has for its object to provide a vibrator device of the type mentioned, which is improved in terms of the storage of the vibrator.

This object is achieved by a vibrator device having the features of claim 1.

Thereafter, it is provided that the vibration generator is mounted in a direction perpendicular to the pivot axis extending about the pivot axis pivotally elastically on the carrier, in particular ball bearing free. That is, the pivot axis can be displaced along all spatial directions encompassed by that plane by a predefinable amount, due to the elastic support, the pivot axis returns to its original position. Preferably, the vibration generator is elastically mounted in two spaced apart along the pivot axis points of the pivot axis, so that the pivot axis can also change their angular position in space, ie, the pivot axis can be rotated from its initial position by a predefinable amount out, here also due to elastic storage takes place a provision in the starting position.

The pivotable mounting of the vibrator ensures that essentially only vibrations of the vibrator are transmitted to the carrier, which take place along the weight of the vibrator (transverse to the pivot axis). That is, in a carrier extended along a horizontal plane, such coupling of the vibrator to the carrier results in periodic movement of the carrier between two reversal points which are opposite to the vertical.

Preferably, the vibrator is also elastically supported on the carrier along the pivot axis, that is, it can be displaced by a predefinable amount along the pivot axis, wherein the elastic bearing also causes a reset of the vibrator in its initial position (force-free position).

The vibrator device according to the invention thus has a low-wear and low-noise storage.

At least one bearing element is provided for the aforesaid elastic mounting of the vibration generator, wherein that at least one bearing element causes a restoring pivoting movement of the vibration generator in the opposite direction of pivoting when the vibration generator is pivoted about the pivot axis in a pivoting direction (rotating the pivot axis).

Such a pivotal movement as part of a pendulum motion of the vibrator arises because the vibrator for generating oscillations preferably by a rotation axis rotating imbalances, which cause a circular oscillation of the vibrator in a direction perpendicular to the pivot axis extending plane. The portions of the circular oscillation pointing along the vertical are transmitted to the carrier, whereas the vibrations directed transversely thereto (along the horizontal) significantly cause the pendulum movement of the oscillator along the horizontal. Of course, due to the pivotal mounting of the vibrator on the carrier, the carrier can also be excited to horizontal oscillations, so that the carrier finally executes a vibration with an elliptical path in a plane perpendicular to the rotation or pivot axis, whose main axis is oriented along the vertical and amount is much larger than the along the horizontal extending minor axis of that elliptical orbit. Ideally, the storage is such that the minor axis disappears and results in a linear, along the vertical extending vibrational path of the wearer.

Preferably, the at least one bearing element for elastic mounting of the vibrator on an elastically deformable body, which preferably surrounds the pivot axis in a direction perpendicular to the pivot axis extending plane. In a variant of the invention that body of the bearing element consists of a rubber.

In one embodiment of the invention, the elastically deformable body is formed as a hollow cylinder, wherein said hollow cylindrical body is positively and materially enclosed by a pivot axis about the first (preferably hollow cylindrical) sleeve, wherein the cylinder axes of the body and the first sleeve coincide. The first sleeve is in particular firmly connected to the outwardly facing outer lateral surface of the elastic body. Furthermore, the at least one bearing element is firmly connected to the carrier via the first sleeve.

The inwardly facing inner circumferential surface of the elastic body is preferably connected to the peripheral axis of the pivoting second sleeve shape and material fit. That is, the second sleeve is encompassed in cross section by both the elastic body and the first sleeve. Since the two sleeves are connected to each other via the elastic body, they can be rotated against each other or the cylinder axes of the sleeves are brought out of alignment, and moved against each other along their cylinder axes, wherein the elastic body causes each of the provision of the sleeves, so that the Cylinder axes of the sleeves coincide and the sleeves along the common cylinder axis are not shifted from each other. Preferably, the cylinder axes of the sleeves and the elastic body coincide with the pivot axis of the vibrator.

Preferably, the bearing element is connected via the second sleeve fixed to the vibration generator. For this purpose, in one variant of the invention, a bolt is in particular inserted in a form-fitting manner into the second sleeve, so that it passes through the second sleeve, wherein a free end portion of the bolt is out of the second sleeve and is connected to a protruding from the vibrator flange, in particular with this is screwed. For this purpose, that free end region of the bolt has a corresponding thread. In particular, the bolt is inserted into the second sleeve so that it coincides with the pivot axis.

For attaching the first sleeve on the carrier, a receptacle on the support for the first sleeve is preferably provided, which is the first sleeve for fixing the at least one Bearing element on the carrier in a direction perpendicular to the pivot axis extending closely engages, so that the first sleeve is held in particular immovable by the recording. Such a receptacle can also be formed on a separate, sheet-shaped carrier plate of the carrier, ie, the carrier can be designed in several parts.

Preferably, a further bearing element is provided for the elastic mounting of the vibration generator, wherein the further bearing element is opposite to a bearing element along the pivot axis. For the construction of the further bearing element that applies above with regard to the one bearing element executed accordingly.

The elastic properties of the bodies of the bearing elements are determined essentially by the geometrical dimensions of those bodies as well as the elastic properties of the materials of which the elastically deformable bodies are made (in the case of elastic bodies made of an elastomer, the elastic properties are essentially determined by the Shore hardness characterized the elastomer).

Particularly preferably, the vibration generator is set up and provided to carry out a vibration in the form of a circular oscillation, wherein the vibration generator is preferably mounted so pivotally on the carrier, that the carrier is excited only to vertical vibrations and horizontal vibrations are largely suppressed.

The carrier of the vibrator device serves to receive a person into whom the vibrations generated by the vibrator and transmitted to the carrier are to be introduced, so that the body of that person is excited to a corresponding vibration (vibration). To accommodate the person, the wearer forms a surface which, in the case of an intended carrier, preferably extends in a horizontal plane, so that a person can stand on that surface of the wearer or can occupy it in some other way. The said vertical vibrations, to which the carrier is preferably excited, thus extend perpendicular to that surface of the carrier. The wearer can hereby absorb the entire weight of that person.

Preferably, the pivot axis about which the vibrator is pivotally mounted on the carrier - relative to the vertical - below that surface, in particular parallel to that surface of the carrier. In this case, the vibrator is arranged along the vertical below the carrier on the carrier hanging, so that the Gravity of the vibrator over the entirety of the bearing elements is introduced into the carrier.

The carrier itself is coupled via at least one spring element to a base plate arranged below the carrier and extending parallel to the carrier, which is set up and provided for placement on a flat base (eg a floor) extending along a horizontal plane. For this purpose, stand from the bottom plate in the direction of the pad feet, over which the bottom plate is supported on the pad. In order that as possible no vibrations are transmitted to the base, the feet are designed to damp elastically deformable vibrations. Preferably, the feet are made of a rubber. The damping properties of the type of storage of the bottom plate are determined by the number of feet, the shape of the feet, and possibly by the properties of the rubber used for the feet (Shore hardness).

Preferably, the at least one spring element is supported on a support element (base) of the base plate which extends perpendicularly to the base plate and protrudes from the base plate in the direction of the carrier, which is in alignment with the spring element. The length of the support element along its extension direction is dimensioned such that the vibrator does not touch the bottom plate even with full compression of the at least one spring element along the extension direction (vertical). Preferably, the bottom plate below the vibrator on a continuous recess (opening). This opening serves on the one hand as a mounting opening through which the vibrator of the vibrator device can be removed or mounted, this opening additionally provides a greater distance between the vibrator and the bottom plate or a below the bottom plate extending pad. In the presence of such openings, the vibrator may thus possibly oscillate beyond the plane of extension of the bottom plate.

Preferably, the carrier is coupled via a plurality of spring elements of the above type with the bottom plate. The spring elements are preferably hollow rubber springs which have a bellows-like shape.

Preferably, the vibration generator is adapted to perform in a plane extending perpendicular to the pivot axis a vibration in the form of a circular movement. The pivotable about the pivot axis storage now ensures that primarily directed perpendicular to the carrier portion of that vibration of the Vibrator is transmitted to the carrier. The transverse oriented portions cause a pendulum movement of the pivotally suspended vibrator, so that the tendency of the wearer to perform an oscillation along its plane of extension is comparatively low.

For generating the oscillation, the oscillation generator has a shaft rotatable about a rotation axis, on which is arranged at least one mass element whose center of gravity is at right angles to the axis of rotation away from the axis of rotation. Preferably, the axis of rotation is parallel to the pivot axis, and preferably below the pivot axis. During the rotation of the shaft, the center of gravity of the vibrator due to this imbalance performs a circular oscillation in a plane extending perpendicular to that axis of rotation. Preferably, a further mass element of the aforementioned type is arranged on the shaft, wherein the two mass elements are preferably each fixed to a free end portion of the shaft and face each other along the shaft.
Preferably, the mass elements are manipulated so that it can be generated from any variable imbalances of the wave. This can for example be realized in that the mass elements each have at least two mutually displaceable (rotatable) parts, which are mutually displaceable against each other (rotatable about the shaft), that the center of gravity of the existing of the two parts mass element transverse to the shaft in the direction the shaft or can be shifted away from it.

In this case, those mutually displaceable or rotatable parts of the mass elements are preferably mounted on the shaft so that the center of gravity of the imbalance shifting or rotation of the two parts of a mass element against each other by a reversal of rotation of the shaft is triggered. In this way, by reversing the direction of rotation of the shaft of the oscillator, the amplitude of the oscillation to be generated can be varied at least between two values (corresponding to the differently sized imbalances of the shaft). The frequency of the oscillation to be generated is largely determined by the rotational frequency of the shaft.

The parts of a mass element (unbalance) preferably have stops that limit the rotation (displacement) of those parts against each other.

FIG. 1 shows in connection with the FIGS. 2 to 6 and 17 a vibrator device 1 according to the invention, with a carrier T, which is supported by four spring elements 70 on a bottom plate 65 arranged along the vertical (in the following z-axis) below the carrier T. At one of the bottom plate 65 facing underside 2 of the carrier T, a vibration generator S is pivotally mounted on the carrier T.

The carrier T forms a surface 60, which extends relative to a vibrator device 1 positioned as intended along the xy plane oriented perpendicular to the z-axis, along which also the base plate 65 arranged below the carrier T or the surface 60 which is designed to be arranged on a flat (running along the xy plane) pad, so that the vibrator device 1 has a stable state. The surface 60 is adapted to be occupied by a person become. For this purpose, that person standing on the said surface 60 of the carrier T, sit or occupy this in any other way. The carrier T can absorb the entire weight of the person.

The support T preferably has a framework T 'for reinforcement (compare in particular FIG FIGS. 15 and 17 ), which preferably consists of a metal, wherein the vibration generator S is preferably connected via that framework T 'to the carrier T. This frame is provided with a cap T "forming the surface 60 of the carrier T. The cap T" may be made, for example, by glass fibers or carbon fibers. in particular fiber mats) or by injection molding.

On the underside 2 of the carrier T are the spring elements 70 of corresponding mounting portions 71 (see. FIG. 15 ) of the frame T 'of the carrier T in a direction extending parallel to the z-axis extension direction in the direction of the bottom plate 65 and depending depending on a support member 75, wherein the support elements 75 respectively from the bottom plate 65 in the direction of the carrier T along protrude a direction parallel to the z-axis oriented extension direction. In this case, the support elements 75 are aligned with the respective associated spring elements 70th According to the Figures 17 and 20 the bottom plate 65 in the center of a continuous opening 65a through which the vibration generator S on the frame T 'of the carrier T can be set or can be removed from the carrier T. Further, this opening 65a ensures sufficient clearance for the vibrator S downwardly. For a secure state and for damping the vibrations generated by the oscillator S, the bottom plate has feet 65b made of a rubber, over which the bottom plate 65 can rest on a flat surface.

From one of the underside 2 facing top 3 of the bottom plate 65 is along the z-axis from a handle 4, on which a person occupying the surface 60, in particular a person standing on it, can comfortably hold. The handle 4 has two mutually parallel end portions 5, 6, over which that handle 4 is fixed to the bottom plate 65, wherein the two end portions 5, 6 are connected to each other via a curved central portion 7. On the handle 4, a control unit 8 is provided, by means of which the vibration generator S can be operated. This includes, in particular, activation, deactivation and adjustment (programming) of the vibration generator S. Furthermore, the control unit 8 can be adjusted by means of a storage means (possibly programmable) settings of the vibration generator S. store, in particular a time course of the frequency and amplitude of a vibration generated by the oscillator S, the duration of the oscillation, exercise sequences, and system settings (eg language of program guide) The memory means may be formed in a development of the invention as a portable storage means (smart card) ,

Thus, the vibrator device 1 is also operable when a person due to their current position in the room, the control unit 8 can not reach, the vibrator device 1 according to the FIGS. 18 to 20 preferably a portable control device 8a in the form of a manual switch, with which the vibrator device 1 in particular on and off. This manual switch 8a can be connected to the vibrator device 1 via a flexible line connection 8b or even without a line. The manual switch 8a can be set as needed on the handle 4

FIG. 7 shows in connection with the FIGS. 8 to 12 the oscillator S. This is to set up and provided to perform a circular oscillatory movement, which is transferable to the support T over the support on the support T, so that the oscillating support T put a person occupying the surface 60 of the wearer T in a corresponding vibration can. In this case, in particular, the entire body of the person can be excited to vibrate. The vibrator device 1 is particularly suitable for the physiotherapeutic treatment and sportive exercise of a person.

For generating the circular oscillation, the oscillation generator S has a motor 87, in particular an electric motor, which drives a shaft 80 extending along a rotation axis A 'so that it rotates about the axis of rotation A'. At two opposite end portions 81, 82 of the shaft 80, a mass element 85, 86 is provided, whose center of gravity does not coincide with the axis of rotation A '. These mass elements 85, 86 thus represent an imbalance, which force upon rotation of the shaft 80 a circular movement (vibration) of the vibrator S in a plane perpendicular to the shaft 80. The motor 87, the shaft 80 and the mass elements 85, 86 are in the FIG. 9 schematically marked.

In order to transform this circular oscillatory motion into a linear oscillation of the carrier T along the z-axis, such that in particular the surface 60 of the carrier T oscillates substantially only along the z-axis, the oscillator S is round a pivot axis A pivotally mounted on the bottom plate 65 facing bottom 2 of the carrier T (suspended).

The pivot axis A is parallel to the surface 60 of the carrier T, that is, parallel to the x-y plane, wherein the axis of rotation A 'of the vibrator S along the z-axis to the pivot axis A is spaced and arranged parallel thereto. In this case, the pivot axis A lies along the z-axis in particular congruent over the axis of rotation A '.

Due to this pivotal mounting, the vibration component of the circular vibration of the vibration generator S extending along the z-axis is effectively transmitted to the carrier T. The component of that oscillation oriented perpendicular to the z-axis results in a pendulum movement of the oscillator S about the pivot axis A, whose influence on the oscillation of the carrier T decreases with increasing distance between the pivot axis A and the axis of rotation A 'along the z-axis, ie , the unwanted horizontal vibrations of the carrier T transverse to the z-axis decrease with increasing distance between the pivot axis A and the axis of rotation A 'from.

In order to store the vibration generator S in the aforementioned manner on the underside 2 of the carrier T, according to the Figures 13 and 14 a sheet-shaped, in particular rectangular support plate 9 is provided, which according to the FIGS. 15 and 16 is fixed centrally on the underside 2 of the carrier T below said surface 60 of the carrier T, preferably on the frame T 'of the carrier T.

For this purpose project from the bottom 2 of the carrier T (in particular from the frame T ') from bolts 61, which engage through corresponding through holes 62 of the support plate 9. The bolts 61 each have an external thread, so that the free end portions of those bolts 61 can be screwed with suitable nuts 63, which press the support plate 9 against the underside 2 of the carrier T. However, the carrier plate 9 may also be formed as an integrally formed on the carrier T region of the support T (in particular of the frame T ').

Of two mutually along the pivot axis A opposite edge regions 64 of the support plate 9, each extending transversely to the pivot axis A, stand two hollow cylindrical receptacles 50 along the z-axis in the direction of the bottom plate 65 from whose cylinder axes coincide with the pivot axis A. These shots are 50 designed to each receive a bearing element 10, 11 for the elastic mounting of the vibrator S on the carrier T.

The two bearing elements 10, 11 each have an outer, first sleeve 20 which is formed as a hollow cylinder and accordingly has an outwardly facing outer lateral surface 21 and an outer lateral surface 21 facing away from the inner lateral surface 22, wherein the cylinder axis of the first sleeve 20 with the pivot axis A is aligned.

About the outer lateral surfaces 21, the two bearing elements 10, 11 each fixed to one of the outer surface 21 facing inner surface 51 of the respective receptacle 50 are connected. For this purpose, the two bearing elements 10, 11 are inserted along the pivot axis A in the receptacles 50.

Thus, the mediated by the bearing elements 10, 11 storage of elastic nature and a displacement of the pivot axis A both transversely to the pivot axis A and along the pivot axis A and further allows a deflection of the pivot axis A, each bearing element 10, 11 an elastically deformable body 25 made of a rubber, which is formed as a hollow cylinder.

The bodies 25 each have an outwardly facing outer lateral surface 26 and an inwardly facing (the outer lateral surface 26 facing away) inner lateral surface 27, wherein they form over their outer lateral surfaces 26 and cohesively with the inner lateral surfaces 22 of the first sleeves 20th are connected. About their inner circumferential surfaces 27, the elastically deformable body 25 are each connected to an outwardly facing, outer circumferential surface 29 of a second hollow cylindrical sleeve 28 of the respective bearing element 10, 11 fixed, which are each arranged coaxially to the first sleeve 20, so that the cylinder axes of second sleeves 28 are also aligned with the pivot axis A. Furthermore, the second sleeve 28 has an inner circumferential surface 30, which faces away from the outer lateral surface 29 of the second sleeve 28. The inner circumferential surface 30 of the second sleeves 28 each define a recess of the second sleeves 28, in each of which a bolt 31 (cf. Figures 9 and 11 ) for attaching the vibration generator S can be inserted. Along the pivot axis A, the two lateral surfaces 21, 22 of the first sleeve 20 and the two lateral surfaces 29, 30 of the second sleeves 28 each bounded by two end faces 20a, 20b and 28a, 28b, respectively along the pivot axis A (or along the cylinder axis of the respective sleeve 20, 28) are opposite.

In this way, the outer first sleeve 20 is elastically coupled via the elastically deformable body 25 with the disposed within the first sleeve 20 second sleeve 28. The elastic body 25 fills in the space between the two coaxially arranged sleeves 20, 28, that is, it is arranged transversely to the pivot axis A between the inner circumferential surface 22 of the first sleeve 20 and the outer circumferential surface 29 of the second sleeve 28. The two sleeves 20, 28 of the bearing elements 10, 11 are preferably made of a metal.

About those second sleeves 28, the vibration generator S is now connected to the bearing elements 10, 11 (see, in particular Figures 9 and 11 ). To this end protrude from the vibration generator S, in particular perpendicular to the axis of rotation A 'two along the axis of rotation A' spaced from each other flanges 40, each having at a free end portion 41 has a recess 42 with an internal thread. Preferably, those flanges 40 are connected to a housing 44 of the vibrator S, which forms a receptacle for the motor 87, the shaft 80 and the mass elements 85, 86. Preferably, the mass elements 85, 86 are each covered by cap-shaped elements 89 of the housing 44.

For fixing the vibration generator S to the two bearing elements 10, 11, a bolt 31 which is aligned with the pivot axis A is inserted into the second sleeve 28 along the pivot axis A and passes through the respective second sleeve 28 with a free end section 32, those free end sections 32 are each screwed into a recess 42, so that the heads 33 of the bolts 31, on the sides facing away from the flanges 40 of the second sleeves 28 against the end faces 28b of the second sleeves 28 press (possibly via washers 33a), whereby the second sleeves 28 with the opposite end faces 28a are pressed firmly against the flanges 40 (this end faces 28a, 28b of the second sleeves 28 preferably extend along the cylinder axis of the second sleeves 28 on the end faces 20a, 20b of the first sleeves 20 addition). Preferably, the bolts 31 do not play in the second sleeves 28, that is, the second sleeves 28 closely surround the bolts 31 in cross section.

Due to the elastic bodies 25, which rotate around the bolts 31 along the pivot axis A at a distance from each other, said elastic mounting of the oscillator S on the carrier T is realized, which allows not only a displacement of the pivot axis A transverse to the pivot axis A and along the pivot axis A, but also a change in the angular position of the pivot axis A in space or with respect to the carrier T. Due to the elastic properties of the two bodies 25 has this storage the tendency to return the pivot axis A in its force-free starting position.

By a suitable choice of the elastic properties of the elastic body 25, in particular the material composition of this body 25, resonances of the vibrator device can be selectively shifted so that they are outside the preferred frequency range of 20-60 Hz, in which the vibrator device is preferably operated. Depending on the design of the vibrator, the frequency may of course also be below or above this interval. The amplitude of the vibration of the carrier T or the surface 60 of the carrier T along the z-axis is preferably 0.5 mm to 5 mm, but may also deviate upwards and downwards from this value range.
