Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in an instrument such as that shown in Patent Document 1, in actuality, vibration is applied by the clitoral stimulation part on the clitoral hood that covers the clitoris, and direct stimulation is not applied to the clitoris, so there is a problem that a woman cannot obtain sufficient pleasure. Further, in order to directly apply the vibration of the clitoral stimulation part to the clitoris, it is necessary to peel back the clitoral hood with a finger and hold the clitoris in an exposed state, and there is a problem that the operability (user-friendliness) of the instrument may impair the pleasure of the woman.

[0005] The present invention has been made to solve the above problems, and an object thereof is to provide an instrument that can give sufficient pleasure to a woman.

Means for Solving the Problems

[0006] The instrument according to the invention described in claim 1, which has been made to achieve the above object, is The gripping part (10) is the part that the user grasps, A contact portion (20) is provided at the tip of the gripping portion and has a communication hole (22a) formed at its tip, A clitoral stimulator (30) is provided inside the contact portion, coaxially with the communication hole, The present invention is characterized by having a drive unit (70) that drives the clitoral stimulator.

[0007] According to this method, when the contact part is pressed against the female genitalia so that the clitoris is centered on the connecting opening, the contact part on the outer circumference of the connecting opening is pressed against the tissue surrounding the clitoris, and the clitoral hood covering the clitoris is pulled outward from the clitoris, exposing it. Then, the clitoral stimulator comes into direct contact with the clitoris, and the clitoris can be directly stimulated by the clitoral stimulator. This makes it possible to provide a device that can give women sufficient pleasure. Conventional devices required the user to retract the clitoral hood with the hand opposite to the one holding the device before pressing the device against the clitoris. However, with the device of the present invention, the clitoral hood can be retracted with only one hand while the clitoral stimulator can be pressed against the clitoris. This allows the other hand to be free, for example, to stimulate one's own erogenous zones, such as the nipples, making it possible to experience greater sexual pleasure.

[0008] The invention described in claim 2 is, in the invention described in claim 1, The diameter of the aforementioned communication hole is characterized by being 8 to 12 mm.

[0009] The inventors of this invention investigated the optimal diameter of the connecting hole for proper clitoral retraction. They discovered that the clitoral retraction is appropriate when the diameter of the connecting hole is between 8 and 12 mm. Thus, by setting the diameter of the connecting hole to 8 to 12 mm, the clitoris can be properly exposed by pressing the contact part against the female genitalia so that the clitoris is centered in the connecting hole. As a result, the clitoral stimulator can be more reliably brought into direct contact with the clitoris, and the woman can more reliably experience pleasure.

[0010] The invention described in claim 3 is, in the invention described in claim 1, The clitoral stimulator is mounted so as to be movable in the axial direction of the gripping portion. The device further includes a movable member (50) that is mounted within the gripping portion so as to be movable in the axial direction and connected to the clitoral stimulator, The clitoral stimulator is configured to be adjustable in its axial direction by the user adjusting the axial position of the movable member.

[0011] According to this, the user can adjust the axial position of the clitoral stimulator relative to the communication hole by adjusting the axial position of the movable member. This allows the user to adjust the pressure of the clitoral stimulator on the clitoris. For example, if the pressure of the clitoral stimulator on the clitoris is too strong and the user feels pain, the user can reduce the pressure to prevent pain. On the other hand, if the pressure is too weak and the user feels insufficient pleasure, the user can increase the pressure to experience more intense pleasure.

[0012] The invention described in claim 4 is, in the invention described in claim 3, An operating part (51) is attached to the base end of the gripping part so as to be retractable in the axial direction, The present invention further comprises a biasing member (52) that biases the movable member toward the base end of the gripping portion.

[0013] According to this design, the user can adjust the axial position of the clitoral stimulator and the pressure applied to the clitoris simply by pressing the operating part with the fingers of the hand holding the gripping part. Therefore, the user can adjust the pressure applied to the clitoris with one hand, providing a user-friendly device.

[0014] The invention described in claim 5 is, in the invention described in claim 3, The aforementioned drive unit is a motor having a rotating shaft, An eccentric member (73) is attached to the rotating shaft or an output shaft to which the rotating shaft is rotationally connected, and an eccentric shaft (73c) is formed with an axis eccentric to the axis of the rotating shaft or the output shaft. The moving member is further provided with a reciprocating member (76) that is arranged to be reciprocable in a direction perpendicular to the axis of the eccentric shaft and engages with the eccentric shaft. The clitoral stimulation part is configured such that the reciprocating motion by the reciprocating member is transmitted thereto.

[0015] According to this, the rotational force by the motor can be surely converted into a reciprocating motion, and the clitoral stimulation part can be made to move based on the reciprocating motion. For this reason, natural stimulation such as caressing the clitoris with a finger or licking the clitoris with a tongue can be given to a woman like actual sexual intercourse, and the woman can obtain more sufficient pleasure.

[0016] The invention according to claim 6 is the invention according to claim 5, wherein A pair of shafts (74) are provided on the moving member so as to face each other. The reciprocating member is characterized in that it is movably attached to the pair of shafts.

[0017] According to this, the straightness of the shaft which is a shape tolerance and the parallelism which is a posture tolerance can be ensured, accurate positioning of the moving member with respect to the shaft can be performed, the reciprocating member is suppressed from tilting with respect to the moving member, and the reciprocating member reciprocates smoothly. As a result, the clitoral stimulation part can be moved smoothly, and the woman can obtain more pleasure.

[0018] The invention according to claim 7 is the invention according to claim 6, wherein A cylindrical bush (75) is movably attached to each of the pair of shafts. The reciprocating member is characterized in that it is movably attached to the shaft via the pair of bushes by holding the pair of bushes.

[0019] According to this, it is possible to further ensure the straightness of the shaft which is a form tolerance and the parallelism which is a posture tolerance, it is possible to further perform accurate positioning of the moving member with respect to the shaft, it is more suppressed that the reciprocating member tilts with respect to the moving member, and the reciprocating member reciprocates more smoothly. As a result, the clitoral stimulation part can be moved more smoothly, and a woman can obtain more pleasure.

[0020] In addition, it is preferable that the bush has a lower frictional force with the shaft than a bush formed in a solid metal cylindrical shape. The bush is preferably a linear bush in which a large number of balls that roll in contact with the shaft are accommodated, a fluororesin (PTFE, polytetrafluoroethylene) having a small coefficient of friction itself, or an oil-free bush in which a lubricant is embedded.

[0021] Thus, when using a bush with low frictional force, the reciprocating member reciprocates more smoothly. As a result, the clitoral stimulation part can be moved even more smoothly, and a woman can obtain even more pleasure.

[0022] The invention according to claim 8 is the invention according to any one of claims 5 to 7, further comprising a transmission member (77) tiltably connected to the reciprocating member. The transmission member is a transmission shaft (77a) connected to the reciprocating member, and a fulcrum shaft (77b) extending in a direction perpendicular to the transmission shaft in the middle part of the transmission shaft, and is provided with, the fulcrum shaft is swingably supported by the moving member, the clitoral stimulation part is attached to the tip of the transmission shaft.

[0023] According to this, the clitoral stimulation part can be swung with the fulcrum shaft as the swing center. For this reason, it is possible to give a woman a natural stimulation such as caressing the clitoris with a finger or licking the clitoris with a tongue like in actual sexual intercourse, and a woman can obtain even more sufficient pleasure.

[0024] The invention described in claim 9 is, in the invention described in claim 8, The dimension from the upper end of the transmission shaft to the axis of the pivot shaft is longer than the dimension from the lower end of the transmission shaft to the axis of the pivot shaft.

[0025] According to this, the force applied to the reciprocating member can be amplified by the lever principle and then transmitted to the clitoral stimulator. Therefore, even if a woman presses the clitoral stimulator firmly against her clitoris, the clitoral stimulator will not stop moving, and will continue to move reliably.

[0026] The invention described in claim 10 is, in the invention described in claim 8, The clitoral stimulator has multiple parts with different tip shapes, The clitoral stimulator is characterized in that one of the clitoral stimulators with different tip shapes can be selected and detachably attached to the tip of the transmission shaft.

[0027] According to this, users can select a clitoral stimulator with a shape that suits their preference and attach it to the transmission shaft. Furthermore, by selecting and attaching different shaped clitoral stimulators to the transmission shaft, users can enjoy different types of stimulation.

[0028] The invention described in claim 11 is, in the invention described in claim 3, The contact portion is mounted so as to be rotatable in the circumferential direction relative to the gripping portion. The movable member is characterized by being rotatably connected to the contact portion.

[0034] (Structure of the device) Below, an embodiment of the device 100 will be described with reference to Figures 1 to 11. As shown in Figures 1 to 5, the device 100 includes a gripping part 10, a contact part 20, a clitoral stimulator part 30, a moving member 50, an adjustment part 62, a power switch 63, a terminal insertion part 65, a drive part 70, a transmission member 77, a battery 91, and a control unit 92.

[0035] The gripping portion 10 is the part that the user grips. The gripping portion 10 is made of synthetic resin and is a vertically elongated, roughly gourd-shaped structure with a cavity 10a (shown in Figures 3 and 4) formed inside. As shown in Figure 1, a narrower constricted portion 10z is formed slightly below the top of the gripping portion 10 compared to the other parts. In this embodiment, as shown in Figure 2, the gripping portion 10 has a dividing surface 10b in the vertical direction and is composed of a first gripping member 11 on the front side and a second gripping member 12 on the back side.

[0036] As shown in Figures 3 and 4, a circular support hole 10d is formed in the center of the upper end portion 10c of the gripping portion 10. A horizontally extending support plate 10g is formed inside the upper part of the gripping portion 10. A support hole 10h is formed in communication with the center of the support plate 10g. A cylindrical mounting portion 10f is formed at the lower end of the gripping portion 10. A pair of fitting protrusions 10x are formed protruding from the inner circumferential surface of the lower end portion of the mounting portion 10f.

[0037] A contact portion 20 is attached to the mounting portion 10f. The contact portion 20 consists of a first member 21, a second member 22, a waterproof member 23, and an O-ring 24. The first member 21 and the second member 22 are made of synthetic resin.

[0038] The first member 21 is a member that is attached to the mounting portion 10f. A cylindrical mounting portion 21a is formed on the upper part of the first member 21. As shown in Figure 6(D), a rectangular engagement hole 21b is formed in communication with the mounting portion 21a. An O-ring groove 21c is recessed around the entire circumference of the outer circumferential surface of the mounting portion 21a, and an O-ring 24 made of synthetic rubber is attached to this O-ring groove 21c. An annular plate-shaped flange portion 21d extending in the outer circumferential direction is formed at the lower end of the mounting portion 21a. As shown in Figure 6, a fitting piece 21f is formed projecting outward at a certain angle from the outer circumferential edge of the flange portion 21d. As shown in Figure 3 and Figure 6(D), a plurality of fitting recesses 21g are recessed at a certain angle from the lower end of the mounting portion 21a. In this embodiment, as shown in Figure 11, a pair of fitting recesses 21g are formed at the lower end of the mounting portion 21a at an angle of 180°.

[0039] As shown in Figure 3, the waterproof member 23 is integrally constructed from a base 23a, an expandable portion 23b, and an enclosing portion 23c, and is made of a flexible material such as rubber or elastomer. In this embodiment, the waterproof member 23 is made of silicone rubber. The base 23a is a disc-shaped (annular disc-shaped) with a hole in the center, and the upper surface of this base 23a is attached to the lower surface of the flange portion 21d of the first member 21 with adhesive, thereby attaching the waterproof member 23 to the first member 21. The expandable portion 23b is formed on the inner circumference side of the base 23a and has a bellows shape that protrudes upward. In this embodiment, the cross-section of the expandable portion 23b is stepped. The expandable portion 23b is expandable and contractible in the vertical direction. The enclosing portion 23c is a bag-shaped structure that protrudes downward from the center of the expandable portion 23b and has an upward opening. The enclosing portion 23c encloses the mounting portion 77c, which will be described later, and has a shape corresponding to the mounting portion 77c. Since the expandable portion 23b is expandable and contractible in the vertical direction, the enclosing portion 23c is movable in the vertical direction relative to the flange portion 21d. The engagement hole 21b is closed by the waterproofing member 23.

[0040] As shown in Figure 3, the mounting portion 21a of the first member 21 is inserted into the mounting portion 10f, and the pair of fitting projections 10x are fitted into the fitting recesses 21g of the mounting portion 21a, thereby attaching the first member 21 to the mounting portion 10f. In this state, the O-ring 24 is in contact with the inner circumferential surface of the mounting portion 10f over its entire circumference.

[0041] The first member 21 is rotatable relative to the mounting portion 10f. In this embodiment, the rotation-preventing mechanism 20x described below prevents the contact portion 20 from rotating beyond a certain angle relative to the gripping portion 10. As shown in Figure 11, the rotation-preventing mechanism 20x consists of a pair of rotation-preventing protrusions 21x, a pair of fitting recesses 21g, a pair of fitting protrusions 10x, and a pair of rotation-allowing recesses 10y.

[0042] As shown in Figure 6(D) and Figure 11, the portion of the outer circumferential surface of the mounting portion 21a of the first member 21 where the aforementioned fitting recess 21g is not formed becomes the rotation-preventing projection 21x. In this embodiment, the rotation-preventing projections 21x are formed in pairs at 180° intervals.

[0043] The portion of the inner circumferential surface of the mounting portion 10f of the gripping portion 10 where the aforementioned fitting projections 10x are not formed is a pair of rotation-permissible recesses 10y. Within the range where the pair of rotation-blocking projections 21x are located within the pair of rotation-permissible recesses 10y, the contact portion 20 is rotatable relative to the gripping portion 10. However, the contact of the contact portion 20 relative to the gripping portion 10 is prevented by the contact of the pair of rotation-blocking projections 21x with the pair of fitting projections 10x. This prevents disconnection of the wiring (not shown) connected to the control unit 92, which will be described later.

[0044] The second member 22 is cylindrical above the middle section and dome-shaped below the middle section. The outer diameter of the lower part of the second member 22 decreases as it moves downwards. A communication hole 22a is formed at the lower end of the second member 22. The diameter of the communication hole 22a is preferably 8 to 12 mm, and in this embodiment it is 10 mm. The inner and outer surfaces around the communication hole 22a at the lower end of the second member 22 are formed with a flexible part 22c made of a flexible material such as rubber or elastomer. As will be described later, this flexible part 22c is the part that is pressed against the tissue surrounding the clitoris of the female genitalia. Because the flexible part 22c is made of a flexible material, when the contact part 20 around the communication hole 22a is pressed against the tissue surrounding the clitoris, it flexibly contacts the tissue, suppressing pain and discomfort for the woman.

[0045] As shown in Figures 6(A) and (B), fitting recesses 22b are formed in the upper inner circumferential surface of the second member 22 at a certain angle in the vertical direction. In this embodiment, three fitting recesses 22b are formed on the upper inner circumferential surface of the second member 22 at 120° intervals. Each of the fitting pieces 21f of the first member 21 is lightly press-fitted into each of the fitting recesses 22b of the second member 22, and the second member 22 is detachably attached to the first member 21. Therefore, by removing the second member 22, the second member 22 and components such as the clitoral stimulator 30 located inside the second member 22 can be cleaned, making it hygienic. As described above, since the engagement hole 21b is closed by the waterproof member 23, even if components such as the clitoral stimulator 30 are cleaned, moisture will not enter the inside of the gripping portion 10. Since each of the fitting pieces 21f is fitted into each of the fitting recesses 22b, when the second member 22 is rotated, the first member 21 also rotates in accordance with the rotation of the second member 22.

[0046] As shown in Figures 3 and 4, a movable member 50 is housed and mounted inside the gripping portion 10 so as to be movable in the vertical direction. The structure in which the movable member 50 is mounted inside the gripping portion 10 so as to be movable in the vertical direction will be described below. As shown in Figure 7, a cylindrical upper support portion 50a is formed at the upper end of the movable member 50. The upper support portion 50a is inserted through the support hole 10h of the gripping portion 10.

[0047] As shown in Figure 7, a pair of plate-shaped lower support portions 50b extending vertically are formed at the lower end of the movable member 50, facing each other and spaced apart. As shown in Figures 3 and 4, the pair of lower support portions 50b are inserted through the engagement hole 21b. This structure allows the movable member 50 to be mounted inside the gripping portion 10 so as to be movable in the vertical direction. Since the expandable portion 23b of the waterproof member 23 is expandable and contractible in the vertical direction, the vertical movement of the movable member 50 inside the gripping portion 10 is not hindered. Only a small gap is formed between the pair of lower support portions 50b and the engagement hole 21b. Therefore, when the second member 22 rotates and the first member 21 rotates, the movable member 50 also rotates, and the clitoral stimulator 30, which will be described later, also rotates.

[0048] As shown in Figure 4, an operating section 51 is attached to the upper support section 50a. The operating section 51 is made of synthetic resin and consists of an outer cylinder section 51a, an inner cylinder section 51b, a top section 51c, and a protruding section 51d. The outer cylinder section 51a is cylindrical in shape. The inner cylinder section 51b is cylindrical in shape and is concentric with the outer cylinder section 51a, positioned inside the outer cylinder section 51a. The top section 51c closes the upper openings of the outer cylinder section 51a and the inner cylinder section 51b, thereby sealing off the outer cylinder section 51a and the inner cylinder section 51b. The lower part of the operating section 51 is inserted through the support hole 10d of the gripping section 10 and is guided by the support hole 10d. The protruding section 51d protrudes downward from the top section 51c inside the inner cylinder section 51b and is cylindrical in shape in this embodiment.

[0049] An engaging projection 50a1 is formed on the outer circumferential surface of the upper end of the upper support portion 50a. A projection 51b1 is formed on the inner circumferential surface of the lower end of the inner cylinder portion 51b, projecting inward along its entire circumference. The upper support portion 50a is inserted through the inner cylinder portion 51b. The operating portion 51 is movable vertically relative to the upper support portion 50a, but the engaging projection 50a1 and the projection 51b1 prevent the operating portion 51 from falling off the upper support portion 50a.

[0050] On the outer circumference of the upper support portion 50a, a coil spring 52 is positioned between the upper surface of the support plate 10g and the lower end of the inner cylinder portion 51b. This coil spring 52 biases the movable member 50 upward.

[0051] When the operating part 51 is pressed, the movable member 50 moves downward, and the transmission member 77 and the clitoral stimulator 30, which will be described later, also move downward, and the tip of the clitoral stimulator 30 moves to the vicinity of the communication hole 22a of the contact part 20.

[0052] As shown in Figures 3 and 4, a cover member 19 made of a flexible material such as rubber or elastomer is provided to cover the gripping portion 10 and the operating portion 51. This cover member 19 prevents moisture and foreign matter from entering the divided surface 10b of the gripping portion 10 and the space between the gripping portion 10 and the operating portion 51.

[0053] As shown in Figure 8, below the upper support portion 50a of the movable member 50, a drive unit housing portion 50c is formed, with a space formed inside. The drive unit housing portion 50c houses the drive unit 70, which consists of a motor 71 and a reduction gear 72. The motor 71 is housed in the upper part of the drive unit housing portion 50c. In this embodiment, the motor 71 is a DC brushed motor. The reduction gear 72 is positioned adjacent to the motor 71 below it. The reduction gear 72 has an output shaft 72a and a plurality of gears (not shown), and the plurality of gears reduce the rotation of the output shaft (not shown) of the motor 71 and output rotational force to the output shaft 72a.

[0054] As shown in Figure 8, below the drive unit housing portion 50c of the movable member 50, a space is formed inside, and a Scotch yoke mechanism housing portion 50d is formed to house the Scotch yoke mechanism described later. The lower support portion 50b mentioned above protrudes downward from the lower end of the Scotch yoke mechanism housing portion 50d. The Scotch yoke mechanism is a mechanism that converts rotational motion into reciprocating motion and consists of an eccentric member 73, a pair of shafts 74, a pair of bushings 75, and a reciprocating member 76.

[0055] As shown in Figures 8 and 9, an eccentric member 73 made of synthetic resin is attached to the output shaft 72a. The eccentric member 73 consists of a base 73a, an eccentric portion 73b, and an eccentric shaft 73c. ​​The base 73a is cylindrical and is attached coaxially to the output shaft 72a. The eccentric portion 73b protrudes horizontally from the lower part of the base 73a. The eccentric shaft 73c is cylindrical with its axis coinciding with the vertical direction and is connected to the end of the eccentric portion 73b. With this configuration, the axis of the eccentric shaft 73c is eccentric with the axis of the output shaft 72a.

[0056] As shown in Figure 8, a pair of shafts 74 are mounted inside the Scotch yoke mechanism housing 50d, their axes coinciding in the width direction and spaced apart in the depth direction. A cylindrical bush 75 is movably positioned on the outer circumference of each of the shafts 74 in the axial direction of the shaft. In this embodiment, the bush 75 is a linear bush containing a number of balls that roll in contact with the shaft 74, resulting in low sliding resistance between the shaft 74 and the bush 75.

[0057] The reciprocating member 76 is located within the Scotch yoke mechanism housing 50d. The reciprocating member 76 is made of synthetic resin and consists of a base 76a, a pair of first support parts 76b, and a second support part 76c. The base 76a is block-shaped. A sliding recess 76d is formed on the upper surface of the base 76a, which has an oval cross-section and whose longitudinal direction is aligned with the depth direction. The eccentric shaft 73c of the eccentric member 73 is inserted through the sliding recess 76d. The first support parts 76b are cylindrical in shape, with their axis coinciding with the width direction, and are connected to both ends of the base 76a in the depth direction. A bush 75 is located inside the first support parts 76b and supports the bush 75. With this structure, the reciprocating member 76 is supported so as to be movable in the width direction within the Scotch yoke mechanism housing 50d. The second support portion 76c has a cylindrical shape with its axis aligned with the vertical direction and protrudes downward from the lower surface of the base portion 76a. The space on the inner circumference side of the second support portion 76c is an insertion hole 76c1.

[0058] As shown in Figure 8, a pivot recess 50e, which is a cylindrical space whose axial direction coincides with the depth direction, is formed as a recess on the opposing surfaces of the lower ends of the pair of lower support portions 50b. As shown in Figures 8 and 9, the transmission member 77 is made of synthetic resin and is a roughly cross-shaped member composed of a transmission shaft 77a and a pivot shaft 77b. The transmission shaft 77a is cylindrical, and its upper end is inserted through the insertion hole 76c1 of the reciprocating member 76 and connected. A gap is formed between the outer surface of the transmission shaft 77a and the inner surface of the insertion hole 76c1. Therefore, the transmission shaft 77a is tiltable relative to the reciprocating member 76. A mounting portion 77c is formed at the lower end of the transmission shaft 77a. As shown in Figure 8, the mounting portion 77c is a block shape with a D-shaped cross-section.

[0059] The pivot shaft 77b is cylindrical and protrudes in the depth direction from the front and rear sides of the outer circumferential surface of the lower end of the transmission shaft 77a. The dimension α from the upper end of the transmission shaft 77a to the axis of the pivot shaft 77b is longer than the dimension β from the lower end of the transmission shaft 77a (including the mounting portion 77c) to the axis of the pivot shaft 77b. It is more preferable that dimension α is 2 to 3 times the dimension β.

[0060] As shown in Figure 8, the pair of pivot shafts 77b are housed in and engaged with the pivot recess 50e. Therefore, the transmission member 77 swings with the pivot recess 50e as the pivot center.

[0061] Figure 10 shows a detailed view of the clitoral stimulator 30. As shown in Figures 3, 4, and 10, the clitoral stimulator 30 is composed of a base portion 31 and a flexible portion 32.

[0062] The base portion 31 is made of a hard material such as synthetic resin and, as shown in Figure 10(D), is composed of a cylindrical portion 31a, a flange portion 31b, and an engaging portion 30c. The cylindrical portion 31a is a bottomed cylindrical shape, opening upward, and has a fitting recess 31a1 formed on its inner circumferential surface whose cross-sectional shape corresponds to the cross-sectional shape of the mounting portion 77c. In this embodiment, the cross-sectional shape of the inner circumferential surface of the fitting recess 31a1 is D-shaped. As shown in Figures 3 and 4, the mounting portion 77c of the transmission member 77 is inserted through the fitting recess 31a1, and the clitoral stimulator 30 is detachably attached to the mounting portion 77c. The clitoral stimulator 30 is provided coaxially with the communication hole 22a of the second member 22 of the contact portion 20, and its tip (lower end) is positioned slightly above the communication hole 22a.

[0063] The inner circumferential cross-sectional shape of the mounting portion 77c and the fitting recess 31a1 is a non-circular D shape, so the clitoral stimulator 30 cannot rotate relative to the mounting portion 77c. This prevents the clitoral stimulator 30 from rotating unintentionally when the user uses the device 100. The flange portion 31b is an annular plate shape and is formed in the middle of the outer circumferential surface of the cylindrical portion 31a in the vertical direction. The mounting portion 31c is formed to protrude downward from the lower end of the cylindrical portion 31a. The mounting portion 31c is roughly cylindrical in shape, but a large-diameter portion 31c1 with a larger outer diameter than the other parts is formed at the lower end. The cross-sectional shape of the large-diameter portion 31c1 is D-shaped.

[0064] The flexible part 32 is made of a flexible material such as rubber or elastomer. In this embodiment, the flexible part 32 is made of silicone rubber. An engaging recess 32a is formed on the upper surface of the flexible part 32, corresponding to the shape of the lower part of the cylindrical part 31a and the mounting part 31c of the base part 31. The mounting part 31c engages with the engaging recess 32a, so that the flexible part 32 is detachably attached to the base part 31. As described above, the cross-sectional shape of the large diameter part 31c1 is D-shaped so that the flexible part 32 does not rotate relative to the base part 31. In this embodiment, as shown in Figure 10(F), the outer shape of the flexible part 32 becomes smaller as it is located towards the tip, and a recess 32b is formed at its tip, so that its tip is bifurcated. When the center of the clitoris is pressed against the recess 32b of the flexible part 32, and the clitoris is held between the bifurcated tip of the flexible part 32, the clitoral stimulator 30 is activated as described later, allowing the female user to experience intense pleasure. In addition to the shape shown in Figure 10, the flexible part 32 is available in several other shapes and can be replaced according to the female user's preference.

[0065] As shown in Figure 1, the first gripping member 11 has an oval-shaped adjustment hole 11a and a circular power switch hole 11b connected to it. As shown in Figure 3, a power switch 63 is located inside the gripping part 10, and as shown in Figure 1, the power switch 63 is exposed through the power switch hole 11b. The power switch 63 switches the device 100 between the ON state and the OFF state each time the user presses it. When the device 100 is in the ON state, current is supplied to the motor 71, and the clitoral stimulator 30 is driven, as will be described later.

[0066] As shown in Figure 3, a disc-shaped adjustment part 62 is rotatably positioned inside the gripping part 10, and as shown in Figure 1, the adjustment part 62 is exposed through the adjustment part hole 11a. The adjustment part 62 is a variable resistor whose resistance value changes depending on its rotational position, and it changes the rotational speed of the motor 71. As shown in Figure 4, the terminal insertion part 65 is positioned inside the gripping part 10 and opens onto the surface of the gripping part 10. Charging terminals for charging the battery 91 are inserted into the terminal insertion part 65.

[0067] As shown in Figure 3, a battery 91 and a control unit 92 are arranged inside the gripping unit 10. The battery 91 is a rechargeable secondary battery such as a lithium-ion battery. The control unit 92 has multiple electronic components mounted on an electronic circuit board and is electrically connected to the power switch 63, adjustment unit 62, battery 91, and terminal insertion unit 65 by wiring (not shown). The control unit 92 supplies a DC current from the battery 91 to the motor 71 using PWM control, with a duty cycle corresponding to the resistance value of the adjustment unit 62. The control unit 92 also charges the battery 91 with the current supplied to the terminal insertion unit 65.

[0068] The operation of the device 100 is described below. When the user presses the power switch 63, current is supplied to the motor 71, and the rotation shaft (not shown) of the motor 71 rotates. Then, the rotational speed is reduced and the rotational torque is amplified by the reduction gear 72, and the output shaft 72a rotates. When the output shaft 72a rotates, the eccentric member 73 rotates, and the reciprocating member 76, which is engaged with the eccentric shaft 73c of the eccentric member 73 in the sliding recess 76d, reciprocates in the width direction. Then, the transmission member 77 swings around the pivot recess 50e as the pivot center, and the clitoral stimulator 30 swings in the width direction around the pivot recess 50e as the pivot center.

[0069] The female user grasps the gripping part 10 and presses the flexible part 22c of the contact part 20 against her genitals, positioning her clitoris in the center of the communication hole 22a. The flexible part 22c on the outer circumference of the communication hole 22a is then pressed against the tissue surrounding the clitoris, pulling the clitoral hood covering the clitoris outward and exposing it. When the operating part 51 is pressed in this state, the moving member 50 moves downward, and the clitoral stimulator 30 also moves downward, bringing the tip of the clitoral stimulator 30 near the communication hole 22a, and the tip of the clitoral stimulator 30 comes into contact with the clitoris, allowing the female user to experience intense pleasure.

[0070] The female user can adjust the pressure applied by the clitoral stimulator 30 to her clitoris to her preference by adjusting the amount of pressure applied by the control unit 51. The user can also change the oscillation speed of the clitoral stimulator 30 to her preference by rotating the adjustment unit 62.

[0071] As described above, when the second member 22 of the contact portion 20 is rotated, the movable member 50 also rotates, and therefore the clitoral stimulator 30 also rotates. By rotating the second member 22 of the contact portion 20, the female user can change the direction in which the clitoral stimulator 30 swings, thereby changing the direction in which the clitoral stimulator 30 swings to give her the most pleasure.

[0072] (Effects of the device) The effects of device 100 are described below. The device 100 includes a gripping portion 10 which is the part that the user grasps, a contact portion 20 provided at the tip of the gripping portion 10 and having a communication hole 22a formed at its tip, a clitoral stimulator 30 provided inside the contact portion 20 coaxially with the communication hole 22a, and a drive unit 70 which drives the clitoral stimulator 30.

[0073] According to this, when the contact portion 20 is pressed against the female genitalia so that the clitoris is positioned in the center of the communication hole 22a, the contact portion 20 on the outer circumference of the communication hole 22a is pressed against the tissue surrounding the clitoris, and the clitoral hood covering the clitoris is pulled outward from the clitoris, exposing the clitoris. Then, the clitoral stimulator 30 comes into direct contact with the clitoris, and the clitoris can be directly stimulated by the clitoral stimulator 30. Therefore, it is possible to provide a device 100 that can give a woman sufficient pleasure. With conventional devices, it was necessary to retract the clitoral hood with the hand opposite to the one holding the device before pressing the device against the clitoris. However, with the device 100 of the present invention, the clitoral hood can be retracted with only one hand while the clitoral stimulator 30 is brought into contact with the clitoris. As a result, one hand is free to use, for example, to stimulate one's own erogenous zones, such as the nipples, making it possible to experience greater sexual pleasure.

[0074] Furthermore, the diameter of the communication hole 22a is 8 to 12 mm.

[0075] The inventors of this invention varied the diameter of the communication hole 22a to investigate the size of the communication hole 22a that allows the clitoral hood to be properly retracted. The inventors discovered that the clitoral hood is properly retracted when the diameter of the communication hole 22a is 8 to 12 mm. Thus, by setting the diameter of the communication hole 22a to 8 to 12 mm, when the contact part 20 is pressed against the female genitalia so that the clitoris is positioned in the center of the communication hole 22a, the clitoris can be properly exposed. Therefore, the clitoral stimulator 30 can be more reliably brought into direct contact with the clitoris, and the woman can more reliably experience pleasure.

[0076] Furthermore, the clitoral stimulator 30 is mounted so as to be movable in the axial direction of the gripping portion 10. The device 100 has a movable member 50 mounted within the gripping portion 10 so as to be movable in the axial direction and connected to the clitoral stimulator 30. The device 100 is configured so that the axial position of the clitoral stimulator 30 can be adjusted by the user adjusting the axial position of the movable member 50.

[0077] According to this, the user can adjust the axial position of the clitoral stimulator 30 relative to the communication hole 22a by adjusting the axial position of the movable member 50. This allows the user to adjust the pressure applied by the clitoral stimulator 30 to the clitoris. For example, if the pressure applied by the clitoral stimulator 30 to the clitoris is too strong and the user feels pain, the user can reduce the pressure to prevent pain. On the other hand, if the pressure is too weak and the user feels insufficient pleasure, the user can increase the pressure to experience more intense pleasure.

[0078] Furthermore, the device 100 includes an operating section 51 that is attached to the base end of the gripping section 10 so as to be retractable in the axial direction, and a coil spring 52 that biases the movable member 50 toward the base end of the gripping section 10.

[0079] According to this design, the user can adjust the axial position of the clitoral stimulator 30 and the pressure applied to the clitoris by simply pressing the operating section 51 with the fingers of the hand holding the grip 10. Therefore, the user can adjust the pressure applied to the clitoris by the clitoral stimulator 30 with one hand, providing a user-friendly device.

[0080] Furthermore, the drive unit 70 is a motor 71 having a rotating shaft. The device 100 has an eccentric member 73 and a reciprocating member 76. The eccentric member 73 is attached to the output shaft 72a, to which the rotating shaft is rotatably connected, and an eccentric shaft 73c is formed, whose axis is eccentric with the axis of the output shaft 72a. The reciprocating member 76 is arranged on the movable member 50 so as to be able to reciprocate in a direction perpendicular to the axis of the eccentric shaft 73c, and is engaged with the eccentric shaft 73c. ​​The clitoral stimulator 30 is configured to receive reciprocating motion from the reciprocating member 76.

[0081] According to this, the rotational force from the motor 71 can be reliably converted into reciprocating motion, allowing the clitoral stimulator 30 to move based on this reciprocating motion. As a result, it is possible to provide women with natural stimulation, such as caressing the clitoris with a finger or licking it with a tongue, just like in actual sexual intercourse, allowing women to experience greater pleasure.

[0082] Furthermore, a pair of shafts 74 are provided inside the movable member 50, facing each other. The reciprocating member 76 is movably attached to the pair of shafts 74.

[0083] According to this, the straightness of the shaft 74, which is a shape tolerance, and the parallelism, which is a posture tolerance, can be ensured, the movable member 50 can be accurately positioned relative to the shaft 74, tilting of the reciprocating member 76 relative to the movable member is suppressed, and the reciprocating member 76 moves back and forth smoothly. As a result, the clitoral stimulator 30 can move smoothly, and the woman can experience greater pleasure.

[0084] Furthermore, a cylindrical bushing 75 is movably attached to each of the pair of shafts 74. The reciprocating member 76 is movably attached to the shafts 74 via the pair of bushings 75 by holding the pair of bushings 75.

[0085] According to this, the reciprocating member 76 is less likely to tilt relative to the moving member 50, and the reciprocating member 76 moves back and forth more smoothly. As a result, the clitoral stimulator 30 can move more smoothly, and the woman can experience greater pleasure.

[0086] Furthermore, the device 100 has a transmission member 77 that is tiltably connected to the reciprocating member 76. The transmission member 77 comprises a transmission shaft 77a connected to the reciprocating member 76, and a pivot shaft 77b extending in a direction perpendicular to the transmission shaft 77a at an intermediate point on the transmission shaft 77a. The pivot shaft 77b is pivotably supported by the movable member 50. The clitoral stimulator 30 is attached to a mounting portion 77c formed at the tip of the transmission shaft 77a.

[0087] According to this, the clitoral stimulator 30 can be oscillated with the pivot axis 77b as the center of motion. As a result, it is possible to provide women with natural stimulation, such as caressing the clitoris with a finger or licking it with a tongue, just like in actual sexual intercourse, allowing women to experience even greater pleasure.

[0088] Furthermore, as shown in Figure 9, the dimension α from the upper end of the transmission shaft 77a to the axis of the pivot shaft 77b is longer than the dimension β from the lower end of the transmission shaft 77a to the axis of the pivot shaft 77b.

[0089] According to this, the force applied to the reciprocating member 76 can be amplified by the lever principle and then transmitted to the clitoral stimulator 30. Therefore, even if a woman presses the clitoral stimulator 30 firmly against her clitoris, the clitoral stimulator 30 will not stop oscillating, and the clitoral stimulator 30 will continue to oscillate reliably.

[0090] Furthermore, the clitoral stimulator 30 has multiple parts with different tip shapes. One of the clitoral stimulators 30 with different tip shapes can be selected and detachably attached to the mounting part 77c formed at the tip of the transmission shaft 77a.

[0091] According to this, a clitoral stimulator 30 of a shape that suits the user's preference can be selected and attached to the mounting part 77c formed at the tip of the transmission shaft 77a. Furthermore, the user can enjoy different types of stimulation by selecting clitoral stimulators 30 of different shapes and attaching them to the mounting part 77c.

[0092] Furthermore, the contact portion 20 is mounted to the gripping portion 10 so as to be rotatable in the circumferential direction. The movable member 50 is rotatably connected to the contact portion 20.

[0093] According to this, the user can rotate the clitoral stimulator 30 to any desired position by rotating the contact portion 20. This allows the direction in which the clitoral stimulator 30 contacts the clitoris to be changed. Thus, the orientation of the clitoral stimulator 30 that allows a woman to experience greater pleasure can be changed.

[0094] Furthermore, as shown in Figure 11, a rotation prevention mechanism 20x is provided to prevent the contact portion 20 from rotating beyond a certain angle relative to the gripping portion 10.

[0095] According to this, breakage of the wiring connected to the motor 71, control unit 92, and battery 91 is suppressed.
