In the illustrated embodiments, preferably a first to fourth guide and support element 3, 3 ', 3 ", 3''' are provided, each at 90 ° to each other concentric around the Longitudinal axis GL of the massaging device 1 are arranged, in such a way that the respective axis of the first to fourth guide and support element 3, 3 ', 3 ", 3"' each having the same distance from the longitudinal axis GL.

In addition to the guide and support elements 3, 3 ', 3 ", 3' '', the drive device 2 a plurality of along the longitudinal axis GL of the massaging device 1 successively arranged, disc-shaped jaw members 4, the first to fourth leadership and Supporting elements 3, 3 ', 3 ", 3' '' are threaded. The jaw elements 4 are preferably circular disk-shaped and flat and each have the same diameter D. The outer or edge surfaces of the jaw elements 4 in this case form support surfaces which abut against the wall or elastic sheath 1.3.

To generate the oscillating movement on the head piece 1.2, the drive device 2 further comprises at least one shaft 5, which preferably extends along the longitudinal axis GL of the massage device 1, wherein its free end facing away from the head piece 1.2 is guided through an opening of the support member 1.1 and thus of the protrudes the head piece 1.2 opposite surface of the support element 1.1. The shaft 5 is rotatably mounted in the carrier element 1.1 and the shaft portion projecting away from the carrier element 1.1 in the direction of the head piece 1.2 has at least one eccentric portion 5 'for driving the circular-disk-shaped jaw elements 4, wherein a rotational movement about the longitudinal axis via a drive unit, not shown in the figures GL or parallel to the longitudinal axis GL extending axis is generated.

The circular-disc-shaped jaw elements 4 each have a plurality of guide holes 6, 6 ', 6 ", 6''' arranged concentrically with respect to their center for receiving the guide and support elements 3, 3 ', 3", 3''', ie with respect to Longitudinal axis GL fixed fixed guide and support members 3, 3 ', 3 ", 3''' pass through the guide holes 6, 6 ', 6", 6''' of the jaw members 4 and are guided by the inner surfaces. In addition, each one the center of the circular disc-shaped jaw member 4 enclosing drive hole 7 to Recording the shaft 5 is provided. Each jaw element 4 is thus designed to be movable radially independently of the adjacent jaw elements 4 ', 4 "radially about the longitudinal axis GL, in a plane running perpendicularly to the longitudinal axis GL of the massaging device 1. The guide holes 6, 6', 6", 6 ''' And the drive hole 7 can hereby have different cross-sectional shapes depending on the massage movement to be generated. For example, they may be slot-shaped, oval or round.

In FIG. 2 is an embodiment with a first to fourth slot-shaped guide hole 6, 6 ', 6 ", 6''' and an elongated oval drive hole 7 and in FIG. 3 with a first to fourth round guide hole 6, 6 ', 6 ", 6''' and a round drive hole 7 exemplified by the inner surface of the guide holes 6, 6 ', 6", 6''' and the drive hole 7 on the one hand and the diameter and / or the outer shape of the guide and support elements 3, 3 ', 3 ", 3''' and the shaft 5 on the other hand, a control curve is predetermined, the movement direction or the radius of movement of the respective jaw member 4 in the perpendicular to the longitudinal axis GL of the massaging device 1 extending plane depending on the rotation angle of the shaft 5 pretends.

The shaft 5 may in this case have different eccentric 5 ', which, for example, in the FIGS. 10 (a), (b) or 11 (a), (b) are shown. In the embodiment according to the FIG. 10 (a), (b) the shaft 5 has a spiral course around the respective wavelength axis WL. In the FIG. 11 (a), (b) illustrated shaft 5 has at least one or more lying in a plane E eccentric 5 'in the form of vibrations about the wavelength axis WL. About the number of distributed over the total length of the drive means 2 oscillations of the shaft 5 and the slope of the spiral, the frequency of the oscillating movement of the head piece 1.2 is at least partially adjustable.

Depending on the design of the shaft 5 in cooperation with the inner surfaces of the guide holes 6, 6 ', 6 ", 6''' and the drive hole 7 results in a displacement of the respective jaw member 4 in the longitudinal axis GL of Massager 1 perpendicular plane and thus in total consideration of the head piece 1.2 of the massaging device 1 along the longitudinal axis GL progressive lifting movement of the jaw members 4, ie the jaw members 4 follow the respective course of the shaft 5. Due to the lifting movement of the jaw members 4 creates an oscillating deformation of the shell 6 to the outside and inwards relative to the longitudinal axis GL of the head piece 1.2.

In an alternative embodiment according to the FIGS. 4 to 6 are provided instead of the guide and support elements 3, 3 ', 3 ", 3''' a plurality of shafts 5.1 - 5.6, the waves longitudinal axes WL are each arranged parallel to the longitudinal axis GL of the massaging device 1 with the same distance in each case .. The waves 5.1 - 5.6 are rotatably mounted in the support element 1.1 and a in the FIGS. 4 to 6 not shown drive preferably synchronously driven to each other. The in the FIGS. 4 to 6 provided shafts 5.1 - 5.6 each have a spiral-shaped eccentric 5 ', which extends from the support member 1.1 along the head piece 1.2. Such a "spiral" type of shaft is exemplary in FIG FIG. 10 shown, in a first side view (a) and after a rotation of 90 ° in a second side view (b).

For example, in FIGS. 4, 5 and 6 a first to sixth, each having a spiral course having wave 5.1 - 5.6, which are provided for receiving a plurality of ball elements 8. For this purpose, the ball elements 8 each have a guide bore 9 through which the respective shaft 5.1 - 5.6 runs, ie the ball elements 8 are consecutively lined up on the eccentric section 5 'of the first to sixth shafts 5.1-5.6 formed by a spiral and thus form a Variety of the spiral shape of the shaft 5.1 - 5.6 replicating support surfaces against which the elastic sheath 1.3 is applied.

The cooperating with the outer surface of the ball elements 8 elastic sheath 1.3 thus forms, for example, a hexagonal cross-section polygon ( FIGS. 5 and 6 ), whose scope is dependent on the distance of the respective ball element 8 to the longitudinal axis L of the massaging device 1. Depending on the angle of rotation of the first to sixth wave 5.1 - 5.6 thus results in an expansion or contraction of the elastic sheath 1.3 by means of the adjacent thereto ball elements 8, whereby the diameter of the rod-shaped massaging device 1 periodically expands or contracts and thus along the longitudinal axis GL progressive oscillatory stroke movement results.

In the FIGS. 5 and 6 is an example of a section through the in FIG. 4 shown headpiece 1.2 of the massaging device 1 along the line AA or BB shown, wherein FIG. 5 the maximum achievable expansion of the elastic sheath 1.3 by means of the first to sixth shaft 5.1 - 5.6 or the ball elements 8 and FIG. 6 the fully contracted elastic sheath 1.3 shows. By a preferably synchronous rotation of the shafts 5.1 to 5.6, the ball elements 8 located on the shafts 5.1 to 5.6 thus move in a plane perpendicular to the longitudinal axis GL, namely alternately from outside to inside and vice versa.

The eccentric portions 5 'of the shafts 5.1 - 5.6 are arranged in such a way to each other in a preferred embodiment that during operation of the massaging device 1 almost simultaneously at different points of the head piece 1.2 is both a maximum and minimum expansion of the elastic sheath 1.3. Alternatively, however, the eccentric portions 5 'of the shafts 5.1 - 5.6 may be oriented in the same direction, i. the spiral eccentric portions 5 'of the shafts 5.1 - 5.6 are parallel to each other. Thus, overall, there is a helical movement of the elastic sheath 1.3 with a constant diameter D.

In a further alternative embodiment of the massage device 1 according to FIG. 7 the drive device 2 consists of a thick-walled tubular element 10 extending along the longitudinal axis GL, which preferably has a round cross-section. The rod-shaped tube element 10 forms a preferably cylindrical cavity 11 for receiving a shaft 5, which is closed by the carrier element 1.1. That the carrier element 1.1 opposite free end of the rod-shaped tube member 10 may be formed either open or closed.

The shaft 5 has a drill-like shape and in turn is rotatably mounted in the carrier element 1.1. In this case, its eccentric portion 5 'is formed by a helix forming edge of the shaft 5, which extends around the longitudinal axis GL of the massaging device 1, and that within the cylindrical cavity 11. The shaft 5 has a deviating from the circular shape, for example, triangular cross section, which is rotated along the shaft axis WL or longitudinal axis GL of the massaging device 1 such that the extremities or vertices of this cross section lie on a helix about the shaft axis WL.

Furthermore, the outer wall of the tubular element 10 has a plurality of guide bores 13, which are distributed along the longitudinal axis GL of the massaging device 1, wherein, for example, a plurality of guide bores 13 are provided in each case in a direction perpendicular to the longitudinal axis GL plane. The guide bores 13 are provided for receiving and guiding preferably solid ball elements 12 which rest against at least one of the eccentric sections 5 '. The ball elements 12 thus interact with the thick-walled tubular element 10 surrounding elastic sheath 1.3 and the drill-like shaft portion 5 'together. The ball elements 12 are in this case against the outer surface of the eccentric 5 'and are pressed by the elastic sheath 1.2 through the respective guide holes 13 of the tubular element 10 on the outer surface of the eccentric 5'.

In the FIGS. 8 and 9 By way of example, the two inflection points of the strokes of the elastic sheath 1.3 which can be generated via the shaft section 5 'are shown. In the present embodiment, three, offset by 120 ° to each other arranged ball elements 12 are each arranged in a direction perpendicular to the longitudinal axis GL of the massaging device 1 level. Along the longitudinal axis GL close to several such ball arrays.

In FIG. 8 is the ball elements 12 has reached the greatest distance from the longitudinal axis GL, in which they protrude beyond the outer surface of the tubular element 10 and are still partially pressed by the elastic sheath 1.3 in the guide holes 13. FIG. 9 shows the state in that the ball elements 12 are completely received in the tube member 10 and its cavity 11, so that the elastic sheath 1.3 abuts directly against the outer surface of the tubular element 10.

By changing from the in FIG. 8 shown outside position in the in FIG. 9 shown inside position and vice versa thus results in an oscillating lifting movement of the elastic sheath 1.3 on the head piece 1.2, which advances due to the drill-like shape of the shaft 5 along the longitudinal axis GL of the massage device 1. The phase of the lifting movement of the ball elements 12 thus changes in the longitudinal direction GL depending on the current rotational position of the shaft 5, from the inboard position to the outboard position and intermediate positions.

The diameter of the guide bores 13 is in this case adapted to the diameter of the ball elements 12. In a preferred embodiment, the guide bores 13 taper slightly outward from the cavity 10, so that the outer radius of the guide bores 13 is smaller than the inner radius of the respective guide bore 13. As a result, leakage of the ball elements 12 is avoided from the guide holes 13.

Instead of a shaft 5 with a drill-like shape can in a massage device 1 according to the FIGS. 7, 8 and 9 also a plurality of concentric with the longitudinal axis of the massager Gl of the massager 1 arranged spiral waves 5.1 - be provided 5.3, as for example in the FIGS. 10 (a) and (b) shown. For example, three such spiral shafts 5.1 - 5.3 arranged and synchronously driven to each other, that a comparable to the use of the drilling-like shaft 5 stroke arises.

The invention has been described above by means of an embodiment. It is understood that numerous changes and modifications are possible without thereby departing from the inventive concept underlying the invention.
