Definitions

  • the present invention relates to an electrically driven massage device according to the preamble of claim 1.
  • Massage devices of the above type are generally known and are used for body massage.
  • the electrically driven, rotating brushes - usually such a device has several rotating brushes - stimulate the skin and promote its blood circulation.
  • the device In order to place the brushes of the massager evenly on the body areas to be massaged, the device, guided by hand, must be aligned with the course of the body parts, so that the brushes lie almost flat with their bristles on the skin zones to cover all brush and bristle areas use and use the massage.
  • Electrically driven massage devices as described above, require a drive train, which is usually constructed from intermeshing gear wheels, which drives the output shaft of the motor with the axes of the brushes.
  • Another massage device which has projecting massage pins over a base plate and which are moved by an electric motor and a gear drive, is known from EP-AO 568 503.
  • the individual pins are guided axially displaceably in a bore in the cover or base plate of the device, whereby they pass through a spring can be pressed into a position retracted into the housing which lies between the inside of the base plate and an enlarged head of the massage stick.
  • the individual heads are in turn supported against a cam plate which is rotated centrally.
  • the cam plate has elevations and depressions, along which the pins are pushed out by rotating the plate over the base plate or, in the region of a recess, pulled back into the housing by the action of the spring.
  • a non-electrically driven massage brush for massaging parts of the body is described in DE-A-39 28 919, which has individual bristle bundles which are held in a housing on corresponding bearing parts and protrude through openings through a base plate of the housing. These bristle bundles can be adjusted in their length with which they protrude above the base plate by a position of the holder which is screwed into the housing differently.
  • the bristles are each held on a ball which is mounted in the holder so that the bristle bundles can oscillate at a slight angle to their longitudinal extent.
  • the bristle bundles can also move about their own axis, overcoming the frictional forces acting between the balls to which the bristle bundles are attached and the corresponding bearing shells; it can be assumed that such a rotation about its own axis only takes place by a small angle of rotation, if at all.
  • This device is conceived as a purely hand-held device, so that the massage is effected solely by guiding the device by hand over the parts of the body to be massaged.
  • the present invention is based on the object of specifying a massage device with rotating brush elements, in which, in contrast to the prior art, a more uniform massage takes place, and in which there is also the possibility of a stronger massage with the brush elements to effect or quasi vigorously walk through skin areas.
  • each brush element is in eccentrically mounted a gear disc that rotates relative to the bearing plate.
  • two superimposed movements are produced according to the invention, one movement being the rotation of the brush element about the holding part, that is to say about itself, and the second movement being the rotation of the brush element about the axis of the carrier disk, so that the brush element moves simultaneously on a circular path while rotating about its own axis.
  • the skin is massaged much better due to the superimposed movements, while the massage location always changes so that the skin can recover in the short term.
  • the brush element is rotated about its own axis by simultaneously rolling in its gear when it rotates around the center of the bearing plate.
  • the bearing plate serves simultaneously as a bearing for the reduction gear and the pinion.
  • the intermediate gear consists of a bearing plate or the like which is fixed to the housing and which is formed in one piece with the intermediate gear.
  • a ring gear or a ring gear is used as a gear according to claim 4, wherein the internal toothing of this ring gear or ring gear engages in the teeth of the brush drive gear.
  • a ring gear or hollow gear has the advantage that with a sufficiently large dimensioning via the internal toothing, several brush elements whose brush drive gearwheels engage in this toothing can be set in rotation at the same time.
  • the toothing geometry and the mounting of the respective brush element allow them to pivot freely by a solid angle, while at the same time they are driven by a gear drive.
  • the extension of the individual teeth of the brush drive gear and the teeth of the intermediate gear, which engage in the toothing of the brush drive gear, is, seen in the direction of the axis of rotation, so long that they are in each pivot position of the corresponding brush element into one another remain in mesh.
  • the features of claim 6 are provided. Due to the pan-shaped mounting on two opposite bearing points, the brush element is rotatably and pivotably mounted both in the axial and in the radial direction. Such storage can be implemented at low cost and represents permanent storage.
  • the pivot point about which the brush element pivots forms the center of those circles or lateral surfaces on which the respective base points and the respective tip circles of the individual teeth lie, so that the different Pivotal positions can also be adopted while rotating the brush elements, without the toothing of the brush element rubbing, crocheting or otherwise jamming in the gearwheel and possibly being destroyed in the process.
  • Such a drive of the brush elements further ensures that the respective brush elements can be rotated almost frictionlessly and with the least noise under a greater load.
  • each brush drive gear is a ring gear arranged on a ball element.
  • the free surfaces of this spherical element i.e. the free surfaces at the upper and lower ends, viewed in the direction of the axis of rotation, are used as bearing surfaces, which are preferably, according to claim 9, mounted on one side in a bearing groove and on the other side in bearing shells.
  • Such a bearing groove in the bearing plate is then adapted according to claim 10 in its cross section according to the radius of curvature of the ball element, so that the ball element can be guided in such an annular bearing groove lying flat.
  • the massage device is preferably designed with two, possibly also with three or four, brush elements, with two brush elements each.
  • elements in opposite directions according to claim 1 1 should rotate in their directions of rotation both about their own and about the axis of rotation of the gear discs.
  • two brush elements with a diameter D of 40 mm each and an opposite movement, which, according to the invention, is also superimposed by an eccentric movement of the brush elements about the axis of rotation of the gear wheel disc can be achieved that the skin not only by the circular brush elements are massaged, but also a flexing effect is caused.
  • the height of the teeth of the bearing plate 4 can be reduced.
  • two brush elements are set in rotation by each gear wheel. As a result, a relatively large number of brush elements can be used if four carrier disks are then evenly rotatably mounted on the circumference of the lower part.
  • an intermediate gear is assigned at least one brush element.
  • two, three or four brush elements can also be assigned to an intermediate gearwheel, which are then rotatably mounted together on a gearwheel disk.
  • 2, 4, 6 or 8 brush elements could then be formed on the massage device.

  • this pivoting about the pivot angle b takes place not only in one plane, but also about a solid angle b, which is determined solely by the opening 11 in the carrier disc 12, in which the holding part 7 is located in the applies respective pivot positions to the inner wall of the opening 1 1 and thereby a further pivoting is avoided.
