Description

The invention relates to a massage toy, in particular a dildo or vibrator or the like, with an essentially cylindrical base body which is formed from a flexible material. The use of a love ball, in particular a smartball (smartballs is a registered trademark of the applicant), and a method for producing a massage toy are also disclosed.

Massage toys of the type mentioned are known in the prior art in many forms, see for example the utility model DE 20 2009 010 633 U1 . Basically, a distinction is made between passive and active toys, with the passive toys generally being referred to as dildos and the active, in particular motor-driven toys, being referred to as vibrators. For this purpose, the vibrators usually have a battery or a rechargeable battery and a motor that drives an imbalance so that a base body of the toy or a section of it is set in vibration and can thus be used for stimulation or massage. The disadvantage here is, in particular, the limited service life of the battery or the rechargeable battery.

Dildos, on the other hand, are usually passive and do not have an electric drive. They usually have a cylindrical base body, which is often essentially modeled on the shape of an erect male genital organ. Furthermore, they often have a widened section or a handle part with which the dildo can be handled, the widened section also serving to limit an insertion depth into a body opening. In addition, dildos for female couples are known which usually have two opposing cylindrical base bodies arranged coaxially or at an angle to one another. The present invention relates to the class of passive, non-powered dildos.

Even if a large number of different dildos are already known on the market, there is still a need to provide dildos with improved properties with regard to suitability for massage, stimulation, in particular stimulation of female genital organs, in particular without an electric drive.

Accordingly, it is an object of the present invention to provide massage toys of the type mentioned at the beginning, a use of love balls and a method for production which are improved with regard to the above-mentioned properties.

The object is achieved in the massage toy of the type mentioned at the outset in that the base body has at least one inner cavity and an inertia body is arranged freely movable in the cavity, the inertia body being designed as a spherical body, the inner cavity having an inner contour which has a larger diameter than the inertial body, so that the inertial body can move freely within the cavity, and wherein at least one dimensionally stable housing is arranged in the base body completely enclosed by this, and the housing defines the cavity, the base body radially on the outside is slightly widened in the area of the cavity.

The inertial body can move within the cavity. As a result of the movement of the inertial body within the cavity, the flexible base body is set in motion and / or vibration, so that improved stimulation can be achieved. Since this is inert, it can hit an inner wall of the cavity when the toy moves accordingly and, when it comes into contact with the wall, gives off impact energy to the base body, causing it to vibrate. Furthermore, the inertial body can roll or slide on the wall of the cavity and thus exert a centrifugal force on the base body when the toy moves accordingly. Furthermore, the movement of the inertial body in the cavity shifts the center of gravity of the base body, which also significantly improves the stimulation. Overall, the invention makes it possible to significantly improve stimulation even in the case of a dildo, without the need for a motor-driven imbalance as is the case with conventional vibrators. Just by moving the dildo by hand, the inertial body starts moving and transfers energy to the base body.

The main body is essentially cylindrical, and preferably modeled approximately in the shape of an erect male genital organ. Essentially cylindrical here refers to the basic shape of the base body and also includes slightly wavy outer contours and slightly curved shapes. The base body itself is preferably formed entirely from a flexible material, which is preferably medically and skin-friendly.

The inertia body is preferably dimensionally stable. The inertial body is capable of moving within the cavity, shifting the center of gravity and generating an energy (e.g. Impact energy) to be transferred to the base body. A dimensionally stable inertial body is particularly suitable for this purpose. The inertia body is preferably dimensionally stable in such a way that it absorbs as little impact energy as possible when it hits an inner wall of the cavity, but rather transfers it as completely as possible to the base body. A particularly good stimulation is achieved in this way. For less intense stimulation, it can also be preferred to use a liquid, instead of the inertial body, the volume of which is less, in particular 50% or less, than the internal volume of the cavity.

The inertia body is designed as a spherical body. A round, in particular spherical shape is a particularly simple shape which, on the one hand, has manufacturing advantages, and on the other hand, such an inertial body can roll within the cavity and thus act as an imbalance when the toy is moved and also transmit impact energy.

The inner cavity has an inner contour which has a larger diameter than the inertia body, so that the inertia body can move freely within the cavity. The cavity preferably has an inner diameter which is larger at each point than the largest diameter of the inertia body. As a result, the inertial body can move particularly freely within the cavity and jamming and the like cannot occur.

At least one dimensionally stable housing is arranged in the base body, completely enclosed by the latter, and defines the cavity. The housing thus encloses a cavity which forms the cavity and an inner surface of the housing defines the contour of the cavity. Since the base body is made of a flexible material, the provision of a dimensionally stable housing around the inertia body allows energy to be transferred particularly well from the inertia body to the base body. The energy, for example impact energy, is not already absorbed by the material of the base body, but rather the energy is first transferred to the dimensionally stable housing, which in turn transfers it along its entire outer surface, which is completely enclosed in the base body.

According to a first preferred embodiment, the base body has two, preferably three, or more inner cavities, and an inertial body is arranged in a freely movable manner in each cavity. This further improves the stimulation. With a preferred axial length of the main body in the range of approximately 17 cm to 22 cm, three cavities can advantageously be provided. With dildos with two opposite one another Base bodies that are intended for female couples can therefore preferably be provided with a total of six cavities. The cavities can all be identical or differ from one another. For example, it can be preferred to make a cavity larger at the front axial end of the base body than at the rear axial end. The reverse configuration is also conceivable and preferred depending on the application.

In a preferred development, the diameter of the cavity exceeds the diameter of the inertial body by a value in a range from 2 mm to 20 mm, preferably 3 mm to 15 mm, particularly preferably 4 mm to 10 mm, more preferably about 6 mm to 10 mm.

It is also preferred that the diameter of the cavity exceeds the diameter of the inertial body by a value in a range from 10% to 100%, preferably 10% to 50%, in particular 10% to 70%, more preferably 20% to 60%, particularly preferably 15% to 30%, or 30% to 50%. With such values and ratios, a play between the inertia body and an inner wall of the cavity is provided, which is sufficient to transmit both a preferred impact energy by providing a sufficiently long distance to accelerate the inertia body, and a vibration transmission due to a Rolling of the inertial body within the cavity and by shifting the center of gravity of the base body.

According to a preferred development, the inertial body has a volume V1 and the cavity has an inner volume V2, and a ratio of the volumes V1 / V2 has a value in a range from 0.1 to 1.0, preferably from 0.1 to 0, 6, particularly preferably 0.2 to 0.5. This also provides a clearance between the inertial body and an inner wall of the cavity, which is sufficient to transfer a preferred impact energy by providing a sufficiently long distance to accelerate the inertial body and to transmit vibrations due to rolling of the inertial body within the cavity and by shifting the center of gravity of the base body.

The inertia body preferably has a mass m1 and the toy has a mass m2, and a ratio of the masses m1 / m2 has a value in a range from 0.01 to 1, preferably from 0.01 to 0.5, particularly preferably 0, 1 to 0.3, most preferably around 0.2. Such a ratio of the masses achieves a "self-dynamic" effect and the toy moves due to a transmission of impulses from the inertial body to the body of the toy. In the case of several cavities with a corresponding number of inertia bodies, the mass m1 relates to the sum of the masses of all inertia bodies.

In a further preferred embodiment, the cavity has an inner contour that is essentially spherical. In a further preferred embodiment, the cavity has an inner contour that is essentially ellipsoidal. Both contours, both spherical and ellipsoid, are particularly preferred if the inertia body likewise has a round, for example spherical or ellipsoidal shape. As a result, the inner contour of the cavity is designed to correspond to an outer contour of the inertial body and the inertial body can roll within the cavity in a particularly preferred manner and thus transfer impact energy due to centrifugal forces to the base body and shift the center of gravity of the base body. Furthermore, corresponding contours have the advantage that there is less noise, which is also preferred. It is desirable that such a toy does not generate any rattling or clicking noises when in use, but rather that it can be operated with as little noise as possible.

According to a further preferred embodiment, the cavity has a main axis and the main axis extends essentially coaxially with a central axis of the base body. According to this embodiment, the cavity is preferably designed to be essentially ellipsoidal. As a result, a movement path of the inertial body in the direction of the central axis of the base body is greater than a movement path radially to the base body, which in turn improves the stimulation with the toy. A shift in the center of gravity along the central axis is greater than radially to the base body, and an impact energy transfer in this direction is also greater. This corresponds more to a natural movement and thus leads to improved stimulation.

It is also preferred that the housing is formed from two half-shells. This is a particularly simple way of forming the dimensionally stable housing and leads to a cost reduction in the assembly and manufacture of the toy. The housing can thus be produced, for example, as an injection-molded part and enclose the inertial body by joining the two housing half-shells.

According to a further preferred embodiment, ribs are formed on an inner wall enclosing the cavity. The ribs preferably protrude in the direction of the cavity, in such a case the inwardly directed end sections of the ribs define an envelope surface which defines the contour of the cavity. The ribs reduce a contact area between the inertia body and the wall or envelope surface of the cavity, which in turn reduces the generation of noise when handling the toy. Is, as in one of the embodiments described above, a housing Provided in the base body which defines the cavity, the ribs are preferably formed integrally on the housing.

Also disclosed is an embodiment according to which at least one love ball, preferably a smartball, is arranged in the base body and according to which the housing of the love ball defines the cavity and the inner ball of the love ball defines the body of inertia. The love ball is preferably a so-called smart ball, as it is developed, manufactured and sold by the local applicant, in particular under the article numbers EAN 4032498331652 and EAN 4032498333083. Such love balls or smartballs or B-Balls are used to strengthen and strengthen the Pelvic floor muscles are provided and have a movable ball inside, which causes the pelvic floor muscles to be stimulated and thereby trained. Such smartballs are particularly suitable for integration into the basic body of the toy and lead to a toy with which a particularly preferred stimulation can be achieved.

In a further preferred embodiment, the base body is formed from a silicone, preferably a medical silicone. Silicone is particularly suitable because it is pleasantly soft and thus creates a particularly pleasant stimulation when using the toy. Above all, the base body is very supple due to an elastic surface structure and enables its outer contour to be adapted to body parts that are massaged or stimulated with the toy.

According to the present invention, the base body is slightly expanded radially on the outside in the region of the cavity. If several cavities are provided, the base body is preferably slightly widened in the area of each cavity. The base body thus has a slightly wavy outer structure. Accordingly, slight constrictions are provided on the body between the cavities. Due to the wavy structure, the toy is better suited for stimulation. A wall thickness of the base body around the cavity is preferably provided in a range from 2 mm to 15 mm, preferably 3 mm to 10 mm. This enables particularly good transmission of the energy from the inertial body or from the housing to the base body and to the outside. If a housing is provided around the cavity, the stated values relate to a wall thickness of the base body around the housing.

Furthermore, the use of a love ball, in particular a smart ball, is disclosed by using the love ball or the smart ball for integration into a base body of a dildo. This achieves the advantages described above. In this respect, reference is made in full to the above description.

A method is also disclosed for producing a massage toy, in particular according to one of the preferred embodiments of a massage toy described above, by pouring at least one love ball, in particular smartballs, into a silicone material to form a base body. The love ball, especially smartball, is to arrange it in a mold and fill the mold with silicone in such a way that the love ball, in particular smartball, is completely enclosed by the silicone material. One, two, three or more love balls are preferably provided. With regard to the further preferred configurations of the massage toy produced in this way, reference is made to the above preferred embodiments of a massage toy and in this respect reference is made to the above description.

In the embodiment of the invention in the form of a vibrator, a vibration or motion sensor is provided which is motor-driven and in which the vibration or motion sensor ensures that the inertial body within the cavity is excited, that is, moved. Such a vibrator also has a corresponding energy source, e.g. a battery.

The invention will be described in more detail below on the basis of an exemplary embodiment with reference to the accompanying figures. Show:

an open case with an inertia body.

According to Figure 1 a massage toy 1 has a base body 2. The base body 2 is essentially cylindrical and has a central axis A which, according to this exemplary embodiment, is slightly curved. The base body 2 is formed from a flexible medical silicone material and is therefore generally elastic, so that it can also be erected in such a way that the central axis A is straight. The base body 2 also has a front axial end 4 and a rear axial end 6. At the rear axial end 6, a flange-like radial extension 8 is provided, which serves to limit the axial insertion depth of the base body 2 from the front axial end 4 to the rear axial end 6. Furthermore, the flange-like radial extension 8 serves as a handle or harness for handling the toy 1.

According to this exemplary embodiment, the base body 2 has three cavities 22 (see FIG Figure 3 and 4th ) and accordingly are in Figure 1 three radial widenings 10a, 10b, 10c on the base body 2 and three radial constrictions 12a, 12b, 12c corresponding to the radial widenings 10a, 10b, 10c, so that the base body 2 is slightly wavy overall. This configuration is also shown in the perspective view in Figure 2 to recognize.

Figure 3 shows a partial full section through the toy 1 along the axis A. The section is only partial, since the cavities 22 themselves and the inertial bodies 24 cannot be seen (see FIG Figure 4 ). According to this exemplary embodiment, the cavities 22 are defined by housings 14a, 14b, 14c, which are shown in FIG Figure 3 are not cut. According to this exemplary embodiment, three housings 14a, 14b, 14c are provided, inside each of which an inertial body 24 (cf. Figure 4 ) is arranged. The housings 14a, 14b, 14c, together with the inertial bodies 24 arranged therein, form a smartball as developed, manufactured and sold by the present applicant. Accordingly, the in Figure 3 The embodiment shown, three smartballs are provided in the base body 2.

According to this exemplary embodiment, the ratio of the sum of the masses of all three inertial bodies 24 to the total mass of the toy 1 is 0.07. How out Figure 3 results, the radial widenings 10a, 10b, 10c are provided in the areas in which the housings 14a, 14b, 14c are arranged in the base body 2. The housings 14a, 14b, 14c have an essentially ellipsoidal or egg-shaped outer contour and are arranged at a distance W _{A from} one another. The housings 14a, 14b, 14c are not connected to one another, even if this can be provided in other embodiments. According to this exemplary embodiment, a housing 14a is provided in the area of the base body 2 which, in relation to a male genital organ, the glans, and two housings 14b, 14c are provided in the area of the base body 2 which, in relation to a male genital organ, the Shank represents. The distance W _A between two adjacent housings 14b, 14c and 14a, 14b is selected such that there is sufficient material here so that the base body 2 can be bent. In addition, a slight constriction is provided on the base body in areas 12a, 12b, 12c. This results in a preferred outer contour, which has already been described above in relation to the Figures 1 and 2 has been described.

On the outside radially, each housing 14a, 14b, 14c is surrounded by a wall thickness W _R (only identified in the case of housing 14c) of the base body 2. The wall thickness W _R is selected so that an energy transfer from the housing 14a, 14b, 14c to the base body 2 and from there to the outside is possible and an absorption by the silicone material of the base body 2 is not too strong. Because the housings 14a, 14b, 14c are dimensionally stable and are preferably formed from a solid plastic, the base body 2 experiences a certain stability and compressive strength, which in turn is preferred for the stimulation.

On a radially outer surface of the housing 14a, 14b, 14c, a rib 16a, 16b, 16c is provided, which serves to establish an improved connection between the silicone material of the base body 2 and the housing 14a, 14b, 14c.

In Figure 4 Both the cavity 22 and the inertial body 24 can be seen in detail. Also in Figure 4 a housing 14 is shown, in the open state, so that the two housing half-shells 18, 20, from which the housing 14 is formed, are dismantled. The housing 14 defines a cavity 22 in its interior, and an inertial body 24 is arranged in the cavity 22. The housing 14 has in both half-shells 18, 20 in each case inwardly directed ribs 26 extending circumferentially around a main axis A (only one rib is provided with reference numerals), wherein the radially inwardly directed end sections 26a of the ribs 26 jointly define an envelope contour which forms the contour of the cavity 22.

According to this exemplary embodiment, the inertial body 24 is designed as a ball, in particular as a ball made of a metal material, hard plastic material, ceramic material or wood material, preferably a material with a relatively high density, preferably a higher density than the density of the base body 2.

The cavity 22 has an essentially ellipsoidal basic shape with a main axis H. The main axis H is in the installed state of the housing (cf. Figure 3 ) aligned so that it is essentially coaxial with the axis A of the base body.

How further from Figure 4 As can be seen, the inertia body 24 is significantly smaller than the cavity 22, that is to say has a smaller diameter. The diameter D _{T of} the inertia body 24 is smaller than the radial diameter D _{K1 of} the cavity 22 and the diameter D _{K2 of} the cavity 22 measured along the main axis H. In particular, the diameter D _{K1 is} about 30% larger than the diameter D _T and the According to this exemplary embodiment, diameter D _K2 is approximately 45% larger than diameter D _K2 . The diameter D _K1 is about 30.5 mm here, while the diameter D _{K2 is} about 26.4 mm. The outer diameter of the housing 14 is approximately 30 mm to 34 mm (in the area of the minor axis of the ellipsoids). As a result, the inertial body 24 can roll within the cavity 22 on the end sections 26a of the ribs and hit them and thus act differently on the base body 2. On the one hand, in the event of a jerky movement, the inertial body 24 can hit the housing 14 and thus transfer impact energy to the base body 2; Centrifugal force is transmitted to the housing, which in turn transmits a vibration to the base body 2. Furthermore, a center of gravity of the base body 2 can be continuously changed by simply displacing the inertial body 24 within the housing 14. All three types produce a particularly pleasant massage or stimulation when the toy 1 is used for massage or stimulation.

The weight of the housing 14 including the inertia body 24 in this exemplary embodiment is in a range from 29 grams to 35 grams, the weight of the inertia body being approximately 20 grams.
