ABSTRACT:
FIELD OF THE INVENTION
This invention relates to vibrating sexual enhancement devices designed to increase sexual stimulation and more particularly to devices that improve gratification during oral-genital sex acts.
BACKGROUND OF THE INVENTION
It is well known by those knowledgeable in the art that vibrating devices can greatly enhance sexual stimulation. In use, these devices typically directly contact the area to be stimulated. Such devices work well when used for self-masturbation whereby the user and the recipient are the same person. This is because the user feels the resulting sensations and he/she is therefore able to optimally manipulate the device. However, when one person uses such devices to stimulate another there is no auto-tactile feedback to the user making it difficult to apply the precise amount of force to precisely the right area. Often too much or too little force is applied, and often to the wrong areas. This can become especially problematic in the case where the device is used for clitoral stimulation. This is because a woman's clitoris can be extremely sensitive, and harsh or direct stimulation can actually be irritating or even painful. Although clitoral stimulation is the only way some women can achieve orgasm, overly aggressive or improper stimulation can accordingly be adversely effective.
An intimate and sensual means of accomplishing clitoral stimulation between sex partners is oral sex, which can be used as a means of foreplay to increase a woman's arousal before intercourse, or as a complete sex act to bring the woman to orgasm. During this act the woman's partner experiences lingual tactile feedback and is therefore more able to effectively control both the force and location of the stimulation given in order to achieve the desired sensations. In an attempt to optimize these sensations the woman's partner often tries to rapidly flick or “vibrate” his/her tongue on and around the woman's clitoris. But due to biomechanical limitations it is difficult, if not impossible, to achieve the sensual cyclic rapidity of an electro-mechanical vibration device.
One form of a certain prior-art device comprises a vibrator that is attached to an elastic ring that encircles the user's tongue. A problem with this device is that it has exposed metal surfaces that can irritatingly contact and, by admission, even damage the user's teeth. In an attempt to address this problem, the device is provided with elastomeric sleeves, however the sleeves only shroud a portion of the metal surfaces leaving major portions uncovered. Also the sleeves are thin-walled and are therefore inadequately effective. Another problem with the device is that since the tongue is compliant and tapers toward its tip, the elastic ring easily slips inappropriately forward to the extent that the vibrator rattles against the user's anterior teeth or even falls out of the user's mouth. Also, the constrictive elastic ring can be quite uncomfortable. In another form of the device, the vibrator is attached to the user's tongue by means of a shaft, which passes through a hole pierced in the tongue and is then screwed into an opposing barbell. A problem with this device is that its use is limited to those individuals having pierced tongues.
Accordingly, there is a need in the art for a comfortable, reliably stabilized device that enables lingual tactile feedback while causing a user's tongue to rapidly, yet gently, vibrate during various oral sex acts such as cunnilingus. And also a device that is useable by anyone.
SUMMARY OF THE INVENTION
The present invention is a device for use during oral sex that causes a user's tongue to vibrate. The device comprises a mouthpiece containing an electrically powered vibrator, and a controller. In the preferred embodiment, the mouthpiece is bilaterally symmetrical to a vertical plane that is coincident with the sagittal plane of symmetry of the user. The mouthpiece includes a constrained portion adapted to fit in the user's mouth below the tongue in a sub-lingual basin that is defined by the lingual surfaces of the mandibular teeth and gums, the floor of the mouth, and a basal portion of the inferior surface of the tongue. The sub-lingual basin has an anterior portion essentially comprising the lingual surfaces of the anterior mandibular teeth and gums. The anterior portion has a substantially cylindrically curved surface having a radius that varies somewhat between different individuals within a range of about 0.75 inch to about 1.0 inch. The constrained portion of the mouthpiece has a length between an anterior end and a posterior end, and a thickness between an upper surface and a lower surface. During use, the upper surface contacts the inferior surface of the users' tongue, the lower surface contacts the anterior portion of the sublingual basin, and the anterior end is situated adjacent the upper edges of the anterior mandibular teeth. The constrained portion is constrained in the sub-lingual basin as it is held against the anterior portion by the inferior surface of the tongue. As used herein, terms such as “anterior”, “posterior”, “upper” and “lower” and other terms describing orientation of features of the mouthpiece relate to the mouthpiece when it is appropriately positioned in the user's mouth as the user's head is upright.
The mouthpiece includes a retaining means for retaining the vibrator in an orientation perpendicular to the vertical plane of symmetry of the mouthpiece. A portion of the upper surface of the mouthpiece adjacent the user's anterior mandibular teeth is preferably situated above an occlusal plane that is coincident with the tops of the mandibular teeth. This assures that vibrations are optimally imparted to the tongue, and also helps prevent the tongue from contacting the tops of the anterior mandibular teeth, which could act to dampen the tongue's vibrations. The vibrator is connected via electrical conductors such as wires to the controller whereby the controller comprises a battery compartment, a battery, and an electrical switch that serves to turn the vibrator on and off. The battery compartment includes a cover that is at least partially removable for the purpose of providing access thereto. The vibrator comprises a capsule made of a rigid material that encapsulates an electric motor having a shaft that has an eccentric weight attached thereto which causes the vibrator to vibrate when the shaft rapidly rotates. The vibrator is preferably approximately 1.0 inch long and about 0.4 inch in diameter. This size satisfies spatial constraints inherent with the location and function of the mouthpiece while allowing for a vibrator having sufficient energy to impart adequate vibrations to the tongue. The vibrator may be permanently encased within the mouthpiece or it may be removable/replaceable. If permanently encased it is hermetically sealed therein to prevent moisture such as saliva from entering the cavity during use or other liquids during cleaning. This protects the vibrator's electronics from possibly shorting and also seals habitats that could harbor and support the growth of deleterious microorganisms. If removable/replaceable, the vibrator itself is hermetically sealed for the same reasons.
The mouthpiece is made substantially of a compliant, resilient material such as silicone, vinyl, or latex or a non-reticulated foamed plastic material. Such materials act to dampen the harsh vibrations of the rigid vibrator against the user's sensitive, unyielding teeth and gums while facilitating the transmission of vibrations to the supple tongue. Also, such compliant materials enable the mouthpiece to yieldingly adapt to fit variations in the anatomical contours of individual user's mouths. Additionally, when the constrained portion is held against the anterior portion of the basin by the tongue, the compliant material embeds into and conforms to irregularities and crevices in the user's teeth and gums, which helps to stabilize the
