• the platelet-shaped body 16aa provided on the first section 16a also extends essentially parallel to the planes 18ba and thus also defines a corresponding virtual plane.
• a virtual plane can be defined in a corresponding manner for the ring-shaped connecting element 19 from its cross-sectional plane or opening plane, which is oriented essentially parallel to the mentioned planes 18ba.
• the distances between the individual virtual planes change. If the moveable structure 16 is pulled apart, the distance between the individual virtual planes increases; and conversely, when the moveable structure 16 is compressed, the spacing between each virtual plane decreases.
• the virtual plane 18ba that is spanned by the fold line 18b between the platelet-shaped body 16aa and the first wall section 18a in the area of the first section 16a of the movable structure 16 has a smaller area delimited by this fold line 18b than the fold line 18b between the annular connecting element 19 and the fourth wall portion 18a in the region of the second portion 16b of the mobile structure 16, while those delimited by the fold lines 18b therebetween Areas from the first portion 16a toward the second portion 16b of the movable structure 16 from virtual plane to virtual plane become larger.
• edge regions of the wall sections 18a each containing a fold line 18b are curved or rounded essentially in the direction transverse to the fold lines 18b, as can also be seen in FIG. 2 .
• the arranged coupling element 26 is provided with a bore 26a, through which a pin (not shown in the figures) is inserted, which protrudes through a complementary bore (also not designated in the figures) in the in Fig. 1 extends the connecting rod 24b shown, as a result of which the connecting rod 24b is coupled to the coupling element 26.
• the wall 40 is provided with flexible or elastic material at least in the area of the fold line 40b.
• the entire wall 18 can preferably consist of flexible or elastic material. Silicone is preferably considered as such a material.
• both the platelet-shaped body 16aa in the first section 16a of the movable structure 16 and the connecting element 19 are made of a less flexible or less flexible, preferably essentially rigid material, which is in particular a suitable plastic.
• the coupling element 26, the plate-like body 16aa in the first portion 16a of the movable structure 16, the wall 18 and the connecting element 19 together form a single piece which, for the sake of simplicity, should be made of the same material;
• the flexibility desired for the wall 18, at least in sections, is achieved in that the wall thickness is significantly less than that of the platelet-shaped body 16aa and the ring-shaped connecting element 19, as can be seen in FIG.
• FIGS. 3a to c are basically the same longitudinal sectional view as FIG. 1, although for reasons of clarity only the movable structure is identified by the reference number, but otherwise, in contrast to FIG. 1, no further reference numbers are given.
• Figure 3b shows the moveable structure 16 in an intermediate position similar to Figures 1 and 2.
• Figure 3a shows the moveable structure 16 in a fully extended position in which the first portion 16a of the moveable structure 16 is a maximum distance of the application opening 8 is located.
• FIG. 3c shows the movable structure 16 in a fully compressed or upset position, in which the first section 16a of the movable structure 16 is at a minimal distance from the application opening 8 .
• the movable structure 16 is alternately pulled apart or lengthened in the manner of an accordion or a bellows and thus brought into the state shown in FIG. 3a and compressed or shortened again and in the state shown in FIG. 3c shown condition.
• the platelet-shaped body 16aa in the first section 16a of the movable structure 16 extends essentially parallel to the plane spanned by the application opening 8 and is subjected to a reciprocal movement essentially at right angles thereto, which is carried out according to the double arrow X im shown in Fig. 1 Is oriented substantially in the longitudinal direction of the hollow body 12.
• the distance between its first section 16a and the application opening 8 and thus from the first end 12a of the hollow body 12 changes at each point by essentially the same amount.
• the structure 16 in such a way that during its re- ciprocal movement, the distance at different points of the first section 16a of the movable structure 16 from the application opening 8 and thus the first end 12a of the cavity 12 changes by a different amount.
• the movable structure 16 is arranged at the inner second end 12b of the hollow body 12 and thus at the point remote from the first end 12a of the hollow body 12 with the application opening. Since in this exemplary embodiment the hollow body 12 forms a single continuous chamber which has an essentially straight tubular shape, the movable structure 16 is thus located opposite the application opening 8 . As a result, the pressure waves generated by the reciprocal movement of the structure 16 and/or correspondingly generated air flows run in the longitudinal direction of the hollow body 12 and are guided by the side wall 14 of the hollow body 12 .
• the movable structure 16 on or in the hollow body 12 in such a way that the direction of movement of the movable structure 16 is at an angle, in particular essentially transverse, to the direction of the pressure field or the reciprocal air flow in the application opening 8 is oriented.
• the movable structure 16 can be integrated into a section of the side wall 14 of the hollow body 12 .
• the pressure wave massage device 1 described according to the embodiment shown in Fig. 1 is designed as a hand-held device and for use with the spout 6 is placed on the body part to be stimulated (not shown in the figures) in such a way that it is in the area of the application opening 8 from the spout 6 is essentially enclosed. During operation, the body part to be stimulated is then alternately exposed to different air pressures and/or air flows by the reciprocal movement of the movable structure 16 .
• any relative excess pressure that may have developed during the respective movement in the direction of the application opening 8 and the resulting shortening of the movable structure 16 due to compression or compression can escape to a large extent. Compression can arise, so that therefore essentially the pattern shown in Fig. 4 of a modulated relative Negative pressure compared to the normal results in a reference pressure Po.
• maximum relative overpressures can occur compared to the reference pressure Po, which, however, can be significantly lower than the minimum of the relative underpressure.
• the amount of the relative overpressure, based on the reference pressure P o is usually no more than 10% of the amount of the relative underpressure, but can also be higher depending on the operating condition and application be.
• the pressure field consists only of a pattern of relative underpressures or relative overpressures, which is modulated onto the reference pressure Po.
• the sinusoidal-periodic pressure curve shown in FIG. 4 results.
• the spout 6 is placed on the body part to be stimulated in such a way that air exchange with the environment does not take place.
• the movement of the movable structure 16 produces pressure waves that change over time, preferably periodically, and that act in the entire hollow body 12 .
• the pressure waves are essentially isotropic and thus also affect the body part to be stimulated. In contrast, there is essentially no air flow.
• the open operation is characterized in that an exchange of air takes place between the hollow body 12 and the environment.
• the spout 6 is placed on the body part to be stimulated in such a way that the application opening 8 only partially encloses the body part to be stimulated and at least one gap-shaped intermediate space remains free between at least one section of the application opening 8 and at least one section of the body part to be stimulated, whereby air can escape from the hollow body 12 into the environment.
• air from the environment in the Hollow body 12 are absorbed, so that in this case there is a regular exchange of air and the air is moved reciprocally within the hollow body 12 in the direction of the longitudinal extent of the hollow body 12, as indicated by the double arrow X in FIG.
• the positive and negative pressures are significantly lower than in sealed operation.
• half-open operation is also conceivable, in which, after the spout 6 has initially been completely placed on the body part to be stimulated, not too strong contact pressures are exerted, so that due to a flexibility of the body part to be stimulated, as already mentioned, possible relative overpressures can escape, while after a negative pressure has developed in the hollow body 12 when the movable structure 16 moves in the direction away from the application opening 8, the sections of the body part to be stimulated that have been opened by the excess pressure are drawn back to the application opening 8 due to the suction effect created thereby, and thus the stimulating body part completely closes the application opening 8 again.
• the body part to be stimulated acts in the manner of a non-return valve.
• the overpressures are considerably lower than in sealed operation, while the negative pressures can be of a similar order of magnitude as in sealed operation.
• half-open operation is the most common application.
• the cross section of the cavity 12 is essentially almost the same, at least in the area of the first section 14a and the central second section 14b of the side wall 14, this means that in open operation the air flow speed in both directions at least there is essentially constant, and in half-open operation to the fact that at least there the air flow rate in the direction of the application opening 8 is also essentially constant.
• a particularly effective air flow can be generated in these operating states for effective stimulation of the part of the body to be stimulated with relatively little energy consumption by the drive motor 22 .
• the previously mentioned control circuit board 28 preferably has a memory, also not shown in the figures, in which different modulation patterns for the generation of pressure waves and the vibration are stored. A desired modulation pattern can then be selected for operation by appropriate operation of the rocker switch 30 .
• the stimulation device 1 preferably has no valves.
