Description

LLEC"I'RO-MECHANICAL SEXUAL STIMULA'I'ION DEVICB

"I'lie present invention relates to the field of sexual paraphernalia. In particular, the present invention provides an electro-mechanical device for sexual stimulation intended for use by women eitlier as an auto-erotic aid or during ititercourse.

'I'llere are numerous devices available for use by women for sexual stimulation. 'I'hey include products that are entirely manually operated, and achieve stimulation by shape and/or texture, and products that are provided with intertlal motors that acliieve stimulation by shape, texture and vibration. 1'hese latter devices, commonly referred to as vibrators, are usually phallus shaped, and are provided with a handle for manipulation in atld around the genital region by a woman. As such, they can generally be used to stimulate only one area at a time. I-lowever, it is known that there are at least three distinct effective genital stimulation areas in most women, namely the clitoris and surrounding skin, the innet-surface of the vagina and the so-called G-spot, a nerve reflex area inside the vagina, alotig the anterior surface.

The applicant is aware of several devices that can be used to stimulate the G-spot, such as that shown in U.S. Patent No. 5,853,362. 'I'his device is generally hook-shaped, so that if

2(} grasped by its shaft, can be inserted into a woman's vagina, and used to massage the G-spot area. Again, this type of device is effective for stimulating only one, and perliaps two (if one considers that stimulation of the G-spot will result in some stimulation of the vaginal wall) areas at a time. "I'he device illustrated is US5$53362 is, like many similar devices, of fairly hard surface construction.

tJS2004/0230093 Al illustrates a device with a handle that is generally U-shaped with an inner arm tet=minating in a curve for stimulating the G-spot, and an outer arm witli a gripping handle and a textured face for clitoral stimulation. 'I'he outer arm of the device may be provided with a cavity into which a small self contained "bullet"
shaped vibrator may be inserted. Essentially, tlien, this device may be used as a manually movable clitoral vibrator, with an artn extending into the vagitia. No direct vibration means effective to stimulate the vagina or U-spot during intercourse are provided.

"I'lie present invention seeks to overcotne the shortcotnings of the prior art by providing a sexual stimulation vibrator appliance that is a significant advance over known vibrators.
"I'he vibrator of the present invention is designed to provide vibratory stitnttlation sitnultaneously to the clitoris, G-spot and vagina. Moreover, the vibrator of the present invention can be comfortably worn durinf; intercourse unlike the devices of the prior art.
The vibrator of the present invention is provided with an internal power source that provides power to two independently operating motors. Moreover, the tnotors can be operated to created a harmonic vibration in the entire device. 'I'l1e vibrator of the preseni invention, moreover, is provided with an itlternal skeleton of either molded plastic and/ot=
pre-shaped tnetal (sueh as a memory alloy) so that use of a very soft silicone body will not i=esult in an appliance that can't hold its shape.

In a broad aspect, then, the present invention relates to a device for use durinl; intercourse by a feniale for sexual stimulation comprising an inner arm diniensioned for inscrtion into a vagina, to contact the wall of the vagina at or near the (i-spot, ati outer arm dimensioned to contact the clitoris, and a resilient lJ-shaped nieniber connecting the inner and outer arms.
In an otller broad aspect, tlien, the present invention relates to a sexual vibrator havint; a first arna including vibratitag nieans, a secoald arm including vibratinl;
nieans, and a slender generally U-shaped nlember connecting the two arnis The inner artn, in a preferred fortn, terminates in a generally teardrop-shaped pad including a rounded inwat-dly directed protuberance.

'I'he outer artn preferably widens fi=otn said U-shaped rnember to its extremity, and has a smooth inner surface adapted to contact the clitoris.

The device may be provided with a resilient inner skeleton covered with a soft, pliable outer layer.

The outer arm defines a clitoral pad that is substantially rectangular or oval, and tapers to meet the U-shaped member. It is of a width such that it may be tucked between the labia majora, in contact with the clitoris.

Moreover, preferably at least one of said inner and outer arms is provided with a vibratory motor and/or electrostimulation and/or mechanical movement all of which may be referred to as vibrator means.

Most preferably, each of said inner and outer anns is provided with a vibratory motor.
Accordingly, each device will be provided with power means.
The power means may a recharageable battery. The rechargeable battery is located in said outer arm.

Accordingly, the outer arm includes an outlet for recharging said battery, and a recharging circuit or a wire.

Furthermore, the outer arm will be provided with switch means. The switch means is capable of actuating said motors in more than one on mode.

In a most preferred embodiment, the device has a silicone outer layer, and a resilient plastic inner skeleton.

In drawings that illustrate the present invention by way of example:
Figure 1 is a perspective view of a first embodiment of the device of the present invention;
Figure 2 is a side view of the device of Figure 1;

3 Figure 3 is a cross-sectional view through line 3-3 of Figure 5;
,= Figure 4 is a front view of the device of Figure 1;
Figure 5 is a rear view of the device of Figure 1;
Figure 6 is a perspective view of a second embodiment of the device of the present invention;
Figure 7 is a side view of the device of Figure 6, also showing a surface texturing in the clitoral stimulation area;
Figure 8 is a cross-sectional view through line 8-8 of Figure 10;
Figure 9 is a front view of the device of Figure 6; and Figure 10 is a rear view of the device of Figure 6.

Referring now to Figure 1, the present invention provides a vibrator/sexual stimulation device that is anatomically shaped, and very flexible. It is shaped to provide an inner arm 1 that terminates in a bulbous teardrop-shaped pad 2 especially visible from Figures 2 and 5. This pad is intended to lie against the region of the vagina near which the G-spot is located. Arm I narrows to a slender U-shaped transition portion 3 and then widens into a broad, flat clitoris stimulator pad 4. The clitoris stimulation pad 4 is fairly flat (as can be seen in Figure 2), and dimensioned in width to fit within the labia majora (see Figure 4).
It will be understood, then, that in use, the clitoral pad 4 is tucked between the labia majora, against the clitoris, and will provide a direct vibration stimulus to the clitoris. The inner arm 1 meanwhile, is inside the vagina, drawn up against the G-spot, and also vibrating. Moreover, it will be understood that a harmonic pulsation will occur in the entire device due to the interaction between the vibrations produced by each motor.

It will also be noted that because the inner arm I is drawn forward in use and the U-shaped admittance arm or transition portion is quite thin and narrow, emplacement of the device will not interfere with ordinary sexual intercourse.

Referring now to Figure 3, it will be observed that the device includes an elastomeric outer skin 5 of silicone, vinyl, rubber, or other suitable material, and an inner core 6 comprising a skeletal core made from a shape memory alloy like Ti Ni, or from a less expensive material,

4 such as a thermoplastic elastomer, or a moulded nylon or polyurethane. Core 6 must be flexible enough to withstand fairly vigorous use, resilient enough to consistently exert a forward pressure on the G-spot and hard enough to protect the components and circuitry located inside it. Located in a first shell 7 at the end of the inner arm 1 toward the tear-drop shaped G-spot pad 2, a longitudinally oriented first vibration motor 8, provided with a small rotating eccentric weight (not shown). Wiring 9 connects the first motor to a second motor located in a shell 71 at the other end of the generally U-shaped core 6, and then further wiring connects two motors to a power source or power means comprising a battery 16 such as an AA or AAA NiCd, a switch 11, preferably a three-position sliding switch, located near 10 the end of the device so that it can be manipulated between an `off position and a pair of `on' positions; and a recharging circuit 12 and outlet 13. As illustrated, recharging outlet 13 may be accessible from the outside, but it may be covered with a removeable plug.
Alternately, recharging circuit 12 may be an induction recharger, not requiring metal to metal contact. It will be understood, moreover, that the number, orientation, and strength of the motors, will be a matter of choice to one skilled in the art. If desired, two or more motors may be provided at each end of the device, or only one motor at each end, or any combination. Furthermore, the switch may be provided with any number of `on' settings to power any combination of the motors at the same or different levels or direction of rotation.
This will create variable harmonic wave patterns in the device, so that a harmonic wave pattern pleasing to the user may be determined on an individual basis.
Moreover, the switch may be a push button, a dial, or any other suitable type of switch.
Furthermore, the core 6 component itself may be made from a bimetallic alloy capable of `twitching' upon application of a current, which may be applied in any desired pattern.

It will also be understood that the device of Figures 1 to 5 may be manufactured with a non-rechargeable battery, and so not be provided with a recharging circuit and outlet.
Accordingly, the unit may be considered disposable after the battery is completely discharged. Alternatively, replaceable batteries may be used. In this case, the device should be provided with a re-sealable access means, such as a peel-back silicone layer, to access the batteries. As shown in the drawings, the vibrator means and the battery may be sealed inside the device.

5 CA 02591401 2007-06-12 pCT/CA2005/001916 26 January 2007 (26-01-2007) Referring now to Figures 6 to 10, a series of views similar to those shown in Figures 1 to 5 is illustrated, for a second embodiment of the device of the present invention. The principle difference in the two devices is that in the case of the second device, the clitoral pad is elongated, aiid formed as a handle for manual manipulation. The outer arm 15 is provided S with second vibrator motor 18. It is not necessary that the wiring 9 to the inner arm motor be contained within the core 6 or shell 7, as it will be covered with a resilient layer of silicone or like material.

The core 6, as shown in Figure 8, is enibodied in the U-shaped curved portion 3 and terminates in the open-ended sliell portion 71 containing a ftrst vibrator motor 10. As can be seen from Figure 8, the interior volume of the device is then occupied by a rechargeable battery 16, followed by a further open shell portion 17, liousing a further vibrator motor 18, a recharge circuit 13, outlet 11, and switch 12. It will be iuiderstood that the shell portion may, if desired, be manufactured as one continuous piece, housing all three motors, the battery, the recharge circuit and the switch. As can be seen in Figure 7, the inner wall of the device in the clitoral pad area 41 may be textured to provide enhanced stimulation.

Since three motors are used in the second embodiment of the device of the present invention, very substantial harmonic wave effects can be created by simultaneous activation of the motors.

It will be understood, nioreover, that many variations of the device of the present invention are possible, without departing from the spirit of the invention.
