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
1

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.

CA 02591401 2009-02-19
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.

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
CA 02591401 2009-02-19
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.

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.
