Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates to the field of vibrating devices used for sexual stimulation. More specifically, the invention comprises a molded cap which can be attached over the bristles of an electric toothbrush.

2. Description of the Related Art

The use of sexual aids such as vibrators of various designs and configurations is known in the prior art. These devices are typically phallic in shape (although unconventional shapes are also employed in the prior art) and are commonly used to stimulate the erogenous zones of the body including the external and internal genitalia. Some sexual aids employ a vibrating mechanism to increase the sexual stimulation provided by the device. These sexual aids are often referred to as vibrators.

It is often desirable for a vibrator to be transportable so that the user can bring the device with them when they travel. Since conventional vibrators employ internal batteries and a motor to create the vibrating motion of the device, the devices can be discovered during luggage screening at airports and in other places where luggage screening is employed. The discovery of a vibrator in these circumstances can create an uncomfortable and embarrassing situation for people who prefer to keep their use of sexual aids private.

BRIEF SUMMARY OF THE INVENTION

The present invention overcomes the problems of the prior art by providing a vibrating device which is discreet and transportable. The invention comprises a molded plastic cap which is adapted to fit over the bristles of the head of an electric toothbrush. The cap features knob-like protrusions for enhanced stimulation.

In one embodiment, the cap features a groove for secured attachment of the cap to the toothbrush.

Another embodiment provides for the use of an adhesive for permanent attachment of the cap to the toothbrush.

The invention provides all of these features, advantages, and objects along with others that will become apparent with reference to the following description and accompanying

DESCRIPTION OF THE INVENTION

A conventional electric toothbrush is shown in FIG. 1. Electric toothbrush 38 is generally composed of grip 26 and wand 28. Aside from serving as means for holding the toothbrush while a user brushes their teeth, grip 26 also serves as a housing for an internal motor and power supply. Most electric toothbrushes are powered by replaceable batteries, but some have an internal rechargeable power source. Grip 26 also generally features an on/off switch which allows the user to actuate the internal motor.

Wand 28 is attached to grip 26. Wand 28 includes brush head 30 and bristles 32. In most electric toothbrushes, wand 28 and grip 26 are detachable, so that the user can replace wand 28 when bristles 32 become worn. Wand 28 also houses a transfer (not shown) that converts the motion created by the internal motor of electric toothbrush 38 into an oscillating motion in brush head 30. In most electric toothbrushes, the head does not spin only in one direction. Instead most brush heads of electric toothbrushes oscillate having alternating positive and negative angles of rotation. Conventional electric toothbrushes typically have a range of angular rotation from +/−20° to +/−100°.

A vibrating cap for attachment to an electric toothbrush is shown in FIG. 2. Cap 10 has sidewall 34 and top 12. Cap 10 can be made of rubber, latex, plastic or other nonallergenic varieties f polymers by the process of injection molding. Sidewall 34 is substantially cylindrical in shape having circular cross section, however other shapes could also be used. Top 12 features three knobs 14 which serve to enhance sexual stimulation by concentrating the pressure and motion of cap 10 to several discrete points on the user. Although any number and configuration of knobs can be used, three knobs placed in an equilateral triangle formation is believed to be particularly effective for the desired stimulation.

FIG. 3 shows the topographical layout of a preferred embodiment. Top 12 is shown with three knobs 14. Although cap 10 can be any size, the preferred range for the diameter is 1.5 cm to 3.0 cm. Knobs 14 are illustrates in FIG. 3 as half spheres although other shapes can also be used for knobs 14 such as cylinders, rounded cylinders, rectangular prisms, pyramids, and cones. Although knobs 14 can be any size, the preferred range for the diameter is 0.5 cm to 1.5 cm. An equilateral triangular formation with knob-to-knob distances 40 in the range of 0.5 cm to 1.5 cm is also preferred.

FIG. 4 shows the molded cap from the bottom. Bottom 36 of cap 10 has bore 16. In the preferred embodiment, bore 16 terminates near the top of cap 10. Bore 16 is preferably sized to receive bristles 32 of electric toothbrush 38 which is typically in the range of 1 cm to 1.5 cm. Counterbore 18 is also provided in bottom 36 of cap 10. The difference in diameter of counterbore 18 and bore 16 forms brush-head seat 42 which mates with brush head 30 of electric toothbrush 38 when bristles 32 are inserted into bore 16.

A bottom view of an alternate embodiment of the present invention is shown in FIG. 5. Cap 10 has two perpendicularly-situated ridges 22 in the bottom of bore 16. Ridges 22 create four compartments 20 in the bottom of bore 16. When bristles 32 are inserted into bore 16 and brush head 30 is mated with brush-head seat 42, bristles 32 separate into the four compartments 20. Ridges 22 provide a surface for bristles 32 to engage when electric toothbrush 30 is switched on, thereby transferring the motion of brush head 30 and bristles 32 to cap 10.

Motion of brush head 30 and bristles 32 can also be transferred to cap 10 by the use of an adhesive applied to bristles 32, brush head 30, bore 16, and/or counterbore 18. The adhesive works to permanently affix the components of cap 10 to brush head 30, thereby insuring transfer of motion between the two parts. Any adhesive known in the art can be used to attach the components including glues, epoxies, silicone-based adhesives, and acrylic resins.

FIG. 6 shows the cap attached to the electric toothbrush. Cap 10 and electric toothbrush 38 are attached by the insertion of bristles 32 into bore 16 of cap 10. As illustrated in FIG. 6, knobs 14 face away from brush head 30. Cap 10 has counterbore 18 (not shown here) so that brush head 30 also fits inside of cap 10, and the back side of brush head 30 is relatively flush with bottom 36 of cap 10.

FIG. 7 shows an alternate embodiment of the cap. Cap 10 features counterbore 18 and partial-annular lip 24. The addition of lip 24 creates groove 44 in the counterbored region beneath lip 24. Groove 44 helps prevent the accidental detachment of cap 10 from electric toothbrush 38 when the two are attached.

FIG. 8 shows the alternate embodiment of the cap attached to an electric toothbrush. Knobs 14 again face away from brush head 30. Bottom 36 is generally flush with the back side of brush head 30 except for lip 24 which overlaps brush head 30 thereby securing cap 10 to the brush.

The preceding description contains significant detail regarding the novel aspects of the present invention. It is should not be construed, however, as limiting the scope of the invention but rather as providing illustrations of the preferred embodiments of the invention. As an example, variations in the number, shape, or configuration of the knob-like protrusions can be employed without altering the function of the invention. Thus, the scope of the invention should be fixed by the following claims, rather than by the examples given.
