Description

The invention relates to a stimulation device for stimulating the female body according to the preamble of claim 1.

Stimulation devices, which are used in particular for women for targeted sexual stimulation of the female body, are known in various designs from the prior art. Such stimulation devices are from the documents US2005 / 273024 . US2015 / 141883 . WO2016 / 033712 A1 . CN102743276 . WO2014 / 008606 . DE102008028221 and US2010 / 076257 known.

That's how it describes EP 1 824 440 B1 a stimulation device, which can be worn by the woman during intercourse and with which the female clitoris and the clitoris-facing area of the vagina can be stimulated simultaneously. For this purpose, the device has a base body with a vibration drive accommodated therein, which has a contact surface which is anatomically adapted to the clitoral region of a woman. Arranged on the base body is a U-shaped bent arm, which has a support body made of a titanium-nickel memory alloy or of a spring-elastic plastic material, the distal end of which can be inserted into the vagina. Since the device is intended to be worn by a woman during intercourse, the turning point of the U-shaped arm is very narrow and thin-walled. The resilient properties of the titanium-nickel memory alloy, or the plastic material that provide the resilient pressure force on the clitoral region when the leg portions are pressed apart when inserting the U-shaped arm in the vagina, hereby represent a reversible plastic deformability of the Material contrary.

The dimensioning of the base body and the arm and the pressure force generated by the resilient arm are chosen in such a way that the stimulation device is held in position during sexual intercourse by the inherent elasticity of the material, without the need for the hand must be used.

The in the EP 1 824 440 B1 described stimulation device has the problem that it is due to the lack of reversible plastic deformability of the used inside hollow support body made of memory metal or made of elastic plastic material is not possible to change the distance between the clitoral contact surface of the body and the arm, without damaging the device, or unusable. As a result, the pressure force with which the clitoral contact surface rests against the clitoral region is determined solely by the elasticity of the material and the distance between the inner wall of the vagina and the clitoral region. As a result, the pressure force is determined solely by the anatomical conditions that are different in each woman, without the possibility that a user of the device can adjust the pressure force to a personally perceived as pleasant level. For the same reasons, the length of the arm section which is received in the vagina when the clitoral contact surface of the main body rests against the clitoral region can not be changed in the described device. As a result, a targeted stimulation of the so-called Gräfenberg point (G-point) is considerably more difficult or even impossible if the clitoral contact surface of the body rests against the clitoris.

Accordingly, it is the object of the present invention to provide a stimulation device for simultaneous stimulation of the clitoris and the vagina, which is adjustable with little effort to different anatomical conditions of the female body.

This object is achieved by a stimulation device with the features of claim 1.

Further features of the invention are contained in the subclaims.

According to the invention, a stimulation device for stimulating the female body comprises a base body on which is formed a clitoral contact surface which is adapted to contact the clitoral area of a woman. On the main body an arm is received, which is insertable with its distal end into the vagina of a woman, while the clitoral contact surface of the clitoral area of the Woman contacted to stimulate this particular by mechanical vibrations.

The stimulation device according to the invention is characterized in that the arm has a core of a reversibly plastically deformable material. The reversible plastic deformability of the core here means that the core can be reversibly deformed from a first position to another second position by applying a sufficiently large external force to the arm outside the region in which an elastic deformation occurs, without the Kern breaks or the material is changed by exceeding the associated yield and expansion limits by the deformation so that it can be bent back with a substantially reduced force in the first position. This makes it possible for the core to remain in a new position after bending it and can only be bent back into the first or another position by applying an approximately equal force.

In order nevertheless to provide a sufficient elasticity of the material when using the device, the core and preferably also the entire base body is surrounded by a shell made of rubber-elastic material. The sheath of the core with the rubber-elastic material, which may for example have a thickness of 1 to 8 mm or more, and preferably consists of silicone or a similar soft and elastic plastic material, or contains such, allows the user that they Core may be deformed into the desired arch shape prior to use of the device by gripping the arm with both hands and applying an increased force to the distal end of the core, or the base body. If the resulting arch shape of the arm does not produce the desired pressure force on the clitoral region after bending, the shape of the stimulation device according to the invention can be readjusted with little effort after removing the distal end of the arm, in which the opposing areas of the distal end of the arm and the body by hand further apart or pressed together.

Likewise, because of the reversible plastic deformability of the material from which the core is made, there is the potential for the position of the distal end of the arm to be displaced relative to the body without altering the clearance between the clitoral contact surface and the arm. if these have previously been deformed, for example, in the shape of a U. This allows the length at which the distal end dips into the vaginal canal upon contact of the clitoral interface with the clitoris to be freely changed.

In addition, the stimulation device according to the invention has the advantage that in a U-shaped configuration described above, the angle between the insertable into the vaginal canal end portion of the arm and located outside of the vagina part of the arm, or the body can be freely changed adapt the shape of the stimulation device to the respective anatomical conditions. It is also possible, for example, to bend the end section of the arm introduced into the vaginal canal in a wave-like or arcuate manner in order to adapt it to the natural course of a vaginally vaginal canal.

In other words, the combination of the reversibly plastically deformable core with the elastic sheath applied thereto allows the stimulation device of the invention to allow the clitoral contact surface to contact the clitoris while the arm is inserted into the vagina and the end of the arm, which is preferably a thickened portion can be positioned exactly in the region of the G-spot of the woman and with a by the elasticity of the silicone material of the conversion uniformized pressure force acts on it gently.

The reversible plastic deformability of the core allows for almost any configuration of the arm with respect to the body, which also allows the arm to be positioned slightly rotated relative to the body so that the distal end of the arm deflect slightly further to the left or right while the clitoral interface stimulates the clitoris.

When the yield strength of the core according to another idea underlying the invention is chosen so that the female genital tissue with inserted device can exert no forces above the yield point on the core, and the length of the core is selected so that the yield strength by By deforming the core by hand with a certain amount of force, the forces which act on the stimulation device, in particular on the core, during use, move in an elastic range below the yield point of the material of the core. In other words, the material, as well as the diameter and length of the core, are preferably selected so that the force / tension needed to deform the arm to exceed the yield point is above the force / tension that is present inserted device is exerted by the genital tissue on the arm, or exercisable. Thus, the stimulation device can be adapted to the individual needs and anatomical conditions of each woman, without the risk that the device will not remain in the newly selected shape after reconfiguration when it is re-inserted into the vagina.

The core preferably has a circular cross-section in the extended, extended state of the arm and, in the case of copper, has e.g. a diameter of 10 mm to 25 mm or even more.

It has proven to be particularly advantageous with regard to the material used if the material has an extended yield strength, which is before reaching the yield point, as is the case in particular with copper or a copper alloy, soft iron or a soft iron alloy.

In this case, a particular advantage of the device is that it can be deformed into different configurations solely by manual force. Other tools for reshaping the core are not required for this, which makes handling very easy even for inexperienced users. The use is facilitated by the fact that in the case of metal, in particular copper, the material usually begins to flow briefly during a deformation of the core after exceeding the yield strength and thus the force required for further movement is usually less than the force, which is needed to exceed the yield strength.

In an exemplary embodiment, the reversibly plastically deformable core accordingly consists of copper or a copper alloy with a copper content of preferably more than 50 wt.% Copper based on the total weight of the metal core. In particular, copper has the advantage that it has an extended yield strength and can thus be converted almost as often into a new configuration without breaking. In addition, the forming force or forming torque required to reshape the copper-molded arm from a first configuration to a second configuration does not substantially change after a plurality of forming operations, but remains nearly constant.

According to another example, the reversibly plastically deformable core is a metal core having at least two partial cores of metal, which are preferably connected at their respective ends by sleeve-like elements. The metal core or the two partial cores are preferably made of solid material, ie of material which has no voids or cavities. This has the advantage that the force required for forming, in particular in the case of copper, does not change significantly even after numerous forming operations. Although it is also possible to solder or weld together the at least two partial cores at the ends and / or over the entire length of the cores, eg by compressing the partial cores and applying a corresponding electrical voltage, these are preferably merely pressed together, which allows a particularly cost-effective production of the core. It has proved to be particularly advantageous In this case, when the two partial cores are additionally twisted in themselves, as this reduces the load on the material during the forming process at the deflection points, in particular in the region of the arc of a U-shaped configuration, and the durability of the metal core is correspondingly improved.

Alternatively, instead of just two split cores, there is the possibility that a plurality of individual copper wires having a diameter of e.g. in each case 0.2 to 5 mm or even more, in particular in the manner of a copper strand, e.g. twisted, woven or spliced together to form the core. These are preferably interconnected at their ends by sleeve-like elements, e.g. frictionally pressed onto the ends. At the same time or alternatively, the wires can also be connected to each other at least selectively by contact welding.

As Applicant has further found, the use of a core of plastically reversible deformable metal in conjunction with the rubber-elastic material sheath provides the further advantage that the arm may be used e.g. by immersing in hot water at a temperature prior to use of the device, the e.g. 10 to 15 ° C above body temperature. In the subsequent use of the device, the core temperature falls due to the relatively high specific heat capacity of the metal and the low temperature difference and the insulating effect of the rubber-elastic coating only slowly from the body temperature, so that the associated additional stimulating effect persists over a longer period of time.

According to another example, the basic body has an elongated, inherently rigid shape. In this case, the area of the base body facing the female intimate area is preferably designed in a stepped manner. This has the advantage that it is arranged on the side of the base body, which is also referred to below as the underside, and originates at the clitoral contact surface and extends from there to the region in which the arm is received on the base body, one to the mold the female vulva has adapted contour.

This means that special when using a vibration drive described in more detail below, the mechanical vibrations can be introduced over a large area in the outer genital area, resulting in a particularly pleasant and gentle stimulation of the entire area.

As already mentioned above, according to a further example, a vibration drive, an energy store and a control device are accommodated in the main body, with which the main body as well as the mechanically coupled arm can be set into mechanical oscillations whose oscillation frequency and / or amplitude are also preferably can be changed via the control device. The vibration drive, for example, a known DC electric motor with an eccentrically mounted on the drive shaft rotating mass, or a piezoelectrically driven actuator, which is attached to the base body and by the control device in the case of the engine with a corresponding variable current, or in the case of the actuator is acted upon by a corresponding periodically changing voltage whose size, or frequency, for example can be varied by means of a potentiometer or switch received on the base body in order to change the frequency of the generated mechanical oscillation.

In the preferred embodiment of the invention, the base body may for this purpose comprise a control part which is mounted on the upper side of the base body, i. is arranged on the opposite side of the clitoral contact surface, and can be operated after insertion of the arm received in the base body in the vagina by hand. The arranged on the control panel switch for switching on and off of the drive, or for changing the mechanical vibration frequency generated by the vibration drive, can be arranged advantageously below the envelope of rubber-elastic plastic material, preferably throughout the arm as well as the Base body extends across.

In order to recharge the energy store, the base body may have at its distal end an electrical contact element whose housing is preferred for Interior of the body is sealed to prevent the ingress of moisture during use, or cleaning. Alternatively, an induction coil and a charging electronics can be arranged in the interior of the main body, via which the energy store can be charged without contact via a known induction charging device. In this case, the envelope of rubber-elastic material may be completely closed.

The control device and the vibration drive are preferably designed such that the vibration drive can be driven by the control device in such a way that the core can be set into a mechanical resonance oscillation. As has been shown, the transmission of the vibrations induced by the vibration drive in the arm mechanical vibrations by the use of a metal, in particular solid copper material as a material for the core positively favors, since the mechanical vibrations in contrast to plastic in the core material forwarded almost without damping losses become.

In a particularly advantageous manner, the base body has an inherently rigid housing made of plastic or else of thin-walled metal, which in the same way as the core is preferably completely surrounded by the rubber-elastic sheath. In the housing, there is the vibration drive, which is preferably arranged directly in the area of the clitoral contact surface or the area assigned to the genital area and is mechanically coupled to the inherently rigid housing, so that the mechanical vibrations generated by the vibration drive are coupled directly into this area. The energy storage device is, for example, a conventional lithium-ion accumulator that supplies both the vibration drive and the control device with electrical energy.

According to a particularly advantageous embodiment, the vibration drive is additionally mechanically coupled to the core, so that the mechanical vibrations generated by the vibration drive are likewise coupled into the core. For this purpose, the core with its end opposite the distal end in a corresponding receiving part, for example a Clamping bracket, be included, which is mounted directly in or on the inherently rigid housing of the body.

The invention will be described below with reference to the drawings with reference to a preferred embodiment of the invention

In the drawings show:

A schematic cross-sectional view of the stimulation device, wherein the arm is in a linear configuration, and

Fig. 2

the stimulation device of Fig. 1 in which the arm has been bent into a C-shaped configuration to use the device.

As in Fig. 1 1, a stimulation device 1 comprises a base body 2 which has a clitoral contact surface 4 which is adapted to contact the intimate area of a woman not shown in detail in the drawings. On the base body 2, an arm 6 is received, which is inserted with its distal end 8 in the vagina of a woman, also not shown. The arm 6 has a core 10a, made of copper or a copper alloy, which is preferably designed as a plastically reversible deformable copper rod with a circular cross-section or an oval cross-section extending over a majority of the length of the arm 6 and from a sheath 12 rubber-elastic material, in particular silicone, is surrounded.

As the representation of Fig. 2 can be removed, the arm 6 can be due to the reversible plastic deformability of the material from the in Fig. 1 shown extended configuration in the Fig. 2 shown U-shaped or C-shaped Configuration and back out of this again Fig. 1 Forming shown configuration without the force or torque, which is spent for forming in the new configuration, significantly reduced even after several forming operations.

Like the presentation of Fig. 2 can be taken in detail, the core 10 has such a length (for example, 12 cm) and such a cross-section (for example, 5 mm) that the distal end 8 of the arm 6 is the base body 2 in the U-shaped configuration opposite and the clitoral area after insertion of the arm 6 in the vagina through the clitoral contact surface 4 and the pubic bone facing portion of the vagina are acted upon by the arm 6 with a resilient contact force.

As the representation of Fig. 1 and 2 can furthermore be removed, at the respective ends of the core 10, which may for example also consist of several partial cores, respectively sleeve-like elements 28, 30 are fixed, which preferably also consist of metal and have on its outer side a polygonal cross-section structure. The sleeve-like elements are pressed or glued, for example, to the ends of the rod-shaped material of the core 10 and serve to connect the split cores together, or to secure the core 10 to the base body 2, or to improve the vibration behavior of the core, as follows will be described in more detail. By the sleeve-shaped element 28 in this case a mechanically fixed connection of the core 10 is obtained on the base body 2, which can be done, for example, that the sleeve-shaped element 28 inserted into a shape adapted female receiving part 29 in the housing 2a of the body, preferably pressed becomes. This receiving part 29 may be formed, for example, as an integral part of the housing 2 a of the base body 2.

As the representation of FIGS. 1 and 2 can be removed, the base body 2 has an elongated inherently rigid shape and has on its underside a clitoris-facing surface 14, which is step-shaped and has an S-shape in cross-section, as indicated in the figures.

In the interior of the main body 2, a vibration drive 16 is arranged, which in the in the FIGS. 1 and 2 As shown embodiment comprises a drive motor 16a, on the drive shaft, a mass 16b is mounted eccentrically. In order to supply the vibratory drive 16 with energy, an energy store 18 and a control device 20 are further accommodated in the housing 2, via which the rotational speed of the drive motor 16a, and thus the mechanical oscillation frequency can be changed. In the case of a drive motor 16a designed as a DC electric motor, this can be done by supplying it with an electrical voltage from the energy store 18 whose height can be changed in the simplest case by means of a variable resistor or in another known manner.

By the accommodated in the receiving part 29 in the housing 2 a of the base body 2 sleeve-like element 28, a rigid mechanical connection between the vibration drive 16 and the rod-shaped core 10 of copper material or other suitable, plastically reversibly deformable material is generated, which ensures that the generated mechanical Vibrations are effectively coupled into the distal end 8 of the arm 6. Due to the further sleeve-shaped element 30, which is attached to the distal end of the core 10 and serves as an additional oscillating element due to its mass, an effective excitation of the distal end 8 of the arm 6 takes place via the rubber-elastic material of the casing 12 on the inner wall of the Vaginalkanals and in particular to the Gräfenberg point is transmitted when the device 1 in the in Fig. 2 shown configuration with the distal end 8 of the arm 6 is inserted in advance in the vaginal canal of a woman.

By the control device 20, the rotational speed of the drive motor 16a hereby preferably can be changed so that the frequency of the mechanical vibration generated by the vibration drive 20 is in the range of at least one of the resonant frequencies of the core 10. As a rule, this changes as a function of the respective spatial configuration of the arm, which is why the rotational speed is preferably infinitely variable via the control device 20.

In order to activate the control device 20 and to change the speed / frequency of the vibration drive 16, the main body 2 comprises a control part 22, which is located on the upper side of the main body 2, so that the device 1 after insertion of the base body 2 received in the arm 6 in the vagina of a woman can be operated by this hand. In order to recharge the energy store 18 after prolonged use of the device, a contact element 26 is preferably located at the head end of the main body 2, via which the energy store 18 can be connected to an electric charger.

As the representation of FIGS. 1 and 2 can still be removed, the base body 2 and the arm 6 are preferably coated by a continuous sheath 12 made of rubber-elastic material, which preferably has a greater thickness in the region of the arm 6, as in the region of the base body 2, and the clitoral contact surface 4th In this case, due to the increasing thickness of the rubber-elastic casing 12, the arm 6 expands from its center towards its distal end 8, wherein at the end of the rod-shaped core 10 in the region of the further sleeve-like element 30, preferably the head-like thickening 12a is formed, which for example is a Diameter of 30 mm and serves to specifically stimulate the Gräfenberg point, while the clitoral contact surface 4 rests against the clitoris of a woman.
