Patent Abstract:
The erogenic stimulator includes a first resilient end region (phallic) extending from a base and a second resilient bulbous end region extending therefrom. The bulbous end is connected via a reduced diameter neck to the base. The base and first and second ends form a truncated substantially U-shaped stimulator. A concave suction element is formed on the base in the curved portion of the U-shape. A passageway may be included from the concave suction element through the base into which may be inserted either a plug or a vibratory element. The plug/vibratory element closes the base end of the passageway thereby permitting expansion and contraction of the passageway dependent upon a predetermined condition at the suction opening of the passageway. If the suction element contacts the skin or an erogenous region and blocks the passageway, the rocking stimulator suctions and evacuates, alternatively, air through the suction opening of the passageway.

Full Description:
The present invention relates to an erogenic stimulator with a suction cup and optionally with an associated chamber for either suction control or insertion of a vibrating unit. 
   BACKGROUND OF THE INVENTION 
   This invention pertains to sexual or erogenous stimulation devices in general and, more particularly, to a self-retained device for simultaneous use by two sexual partners such that the erotic areas of both such users are concurrently excited. 
   GENERAL BACKGROUND 
   Marital or sexual aids have been known and used throughout the centuries. Generally, such aids have been designed either for self-stimulation or for the stimulation of one party only. However, some aids satisfy two partners at the same time. This latter type of aid or stimulators is designed primarily for use by a female user and often incorporates a flexible phallic shaped stimulator secured to a base. Variations of this type of stimulator include two such phallic shapes linearly secured to opposite sides of a common or intermediate flange. Unfortunately, because of the co-linear nature of these opposite shapes, the simultaneous use of such a device by two partners requires some gymnastic-like maneuvers. 
   Also, it is common for these devices to not be self-retaining, that is, when one end is retained in the vagina or anal cavity, the other end is free to stimulate of the other person. Instead, these devices rely upon a series of straps in order to hold and retain the device in place on one user for proper use on the other person. However, fastening such straps prior to use is cumbersome and discomforting and causes undesirable delay. 
   U.S. Pat. No. 5,690,603 to Kain discloses a self-retaining stimulator, that is, when one end is retained in the vagina or anal cavity, the other end is free to stimulate the other person. 
   OBJECTS OF THE INVENTION 
   It is thus an object of the present invention to provide a marital or sexual aid that is capable of simultaneously stimulating the erotic areas of both users. 
   It is a further object of this invention to provide an aid that is self-retaining such that straps or other holding devices are not required, thereby eliminating any delay and discomfort. 
   A further object of this invention is to provide a device that is capable of being used by partners of the same sex or of the opposite sex. 
   Still another object of this invention is to provide a device that is capable of flexing as needed but which returns to its original position upon its release. 
   Yet another object of this invention is to provide an aid that is smoothly contoured for comfort. 
   An additional object is to stimulate the clitoris of one of the users with a suction element during sexual play with the stimulator. 
   A further object of the present invention is to develop a suction chamber which co-acts with the suction element thereby enhancing the sexual play with the stimulator. 
   SUMMARY OF THE INVENTION 
   In one embodiment, the erogenic stimulator includes a first elongated, resilient, cylindrical end region (typically a phallic shape) with a first end extending from a proximal base end and a second resilient, cylindrical, bulbous end region also extending from a proximal base end. The bulbous distal end is connected via a reduced diameter neck to that base. The base is further connected to the first end region. The base, the first phallic end and the second bulbous end extend upwards from the base forming a truncated substantially U-shaped stimulator. The stimulator includes a concave suction element on the base in a curved portion of the truncated U-shape. Other features include: a passageway from that bottom of the concave suction element through said base, into which may be inserted either a plug or a vibratory element. The plug/vibratory element closes the base end of the passageway thereby permitting expansion and contraction of the passageway dependent upon a predetermined condition of the suction opening of the passageway. If the suction element contacts the skin or erogenous region of one user and the plug/vibratory element blocks the passageway, a rocking or undulation of the stimulator suctions and evacuates, alternatively, air through the suction opening of the passageway. This suction and evacuation of air further energizes the skin or erogenous region of the user. The base may have a cut-away for removal of the plug/vibratory element.

   DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
   The present invention relates to a erogenic stimulator or martial aid. 
   Similar numerals designate similar items throughout the drawings and specification.  FIG. 1A  diagrammatically illustrates stimulator  10  having a first elongated, resilient and generally cylindrical end region  12 . In the preferred embodiment, end region  12  has a phallic shape. First end region includes a first distal end  14  and a first proximal base end generally identified at end portion  16 . Stimulator  10  includes a second resilient and generally cylindrical end region  18  sized for receipt in an anal or vaginal cavity. Second end region  18  includes a second bulbous distal end  20  and a second proximal base end generally near portion  22 . This bulbous distal end  20  is connected via a reduced diameter neck portion or neck  24  between the bulbous end  20  and the second proximal base end  22 . The second end region includes the bulbous element, the neck and the base end  22 . Neck  24  enables bulbous end region  20  to flex thereat. Bulbous end  20  is adapted to permit the muscle groups of one of the partners using the stimulator to hold the second end in place during use. An alternative construct of the invention eliminates the neck and bulbous nature of second end  18 . 
   Stimulator  10  includes a base  30  connected intermediate first proximal base end  16  and second proximal base end  22 . First end region  12  and second end region  18  extend upwards from base  30  and forms a truncated, substantially U-shape stimulator. The U-shape is truncated since the second end region  18  is smaller in length then the first end region  12 . Hence one of the legs of the U-shaped stimulator is truncated or shorter compared to the other leg. The U-shaped stimulator has a curved region  33 . The U-shape of stimulator  10  may also be considered to be an L-shape due to the truncated nature of the bulbous end  18 . The L-shape is rotated such that the intersection between the upper leg of the L-shape and the base of the L-shape is the location of the suction cup  32 . Reference to a U-shaped stimulator is meant to cover an L-shaped stimulator herein. 
   A concave suction element  32  is mounted, attached or formed as part of the base in curved portion  33  of the truncated U-shape stimulator. Suction element  32  rises above or is formed on curve  33  of the U-shaped stimulator  10 . Concave suction element  32  has a outer rim  34  rising above surface  35  of curve portion  33  of the truncated U-shape stimulator in the preferred embodiment. Outer rim  34  may be a circle, oval, ellipse, triangle, square, polygon, rectangle or a diamond shape. The suction element may have a low rise rim and be primarily formed by a depression in base  30 . 
   Concave suction element  32  has an interior space  36 . In one embodiment (an alternative embodiment), a passageway  38  leads from the base of interior  36  of suction element  32  and extends outboard or away from the suction element  32  and exits base  30  opposite curve portion  33  of the concave U-shape stimulator. Accordingly, passageway  38  has a first opening at the base of suction element  32  and a second opening on base  30  opposite curve region  33  of the truncated U-shape. 
   A removable plug or a vibrating element  40  is sized to fit snugly within passageway  38  and to extend either fully or partially into passageway  38  as shown by arrow  41  in  FIG. 1A . In order to assist the user to remove or insert removable plug/vibrator element  40 , base  30  may have a cut-away  50  about the second opening  49  of passageway  38 . One type of small, cylindrical vibratory element is a MAGIC BULLET vibrator. Passageway  38  may extend at various angles from suction element  32 . Auxiliary passageway  60  (an angled chamber) is shown in  FIG. 1A  with a dash-dot-dash line as an alternative route. Rather than a vertical passage, angled passageway  60  also works. Passageway  60  has an opening  61  generally opposite curved portion  33  of truncated U-shaped stimulator  10 . A cut-away  63  may also be provided at opening  61  of chamber  60 . Chamber  60  is sized to receive fully or partially a vibrating element. The vibratory element may be longer than passageway  38 ,  60 . If the element slightly extends into the bottom of the suction element bowl  36 , removal is easier. 
     FIG. 1B  shows that removable plug  40  or vibrating element  40  has been partially inserted into passage  38 . 
   In operation, one partner places bulbous distal end  20  in an anal or vaginal cavity and the first cylindrical end region  12 , preferably having a phallic shape, is inserted into an anal or vaginal cavity of the other partner. 
   When removal plug or vibratory unit  40  is inserted into passageway  38 , passageway  38  is partially closed. When in use, concave suction element  32  contacts the skin and erogenous zones of one of the partners. When suction element  32  (particularly rim  34 ) is in contact with skin or other erogenous body zone, and the stimulator  10  moves or rotates due to thrusting or rocking motion of one partner with respect to the other partner, suction is created and then released in truncated cavity  38  shown in  FIG. 1B . Air is trapped when suction opening  37  is closed. If open, air is ejected from the passage. Thereafter upon close contact to the skin or erogenous zone, the passageway draws air therein enhancing the suction at element  32 . Without the passageway  38 ,  60 , suction is developed by flexing action of cup  32  on the skin or erogenous zone. Therefore, the suction element  32  enhances the sexual play of the users. The degree of suction is controlled by the inserted location of plug or element  40 . The inclusion of a vibratory element  40  or a removable plug also affects the sexual play of the users. Cut-away  50  permits the plug to be removed or vibratory unit to be removed from chamber  38 . The predetermined condition of the suction opening (or suction cup rim) depends upon an open or closed position with respect to the skin or erogenous zone. 
     FIG. 1C  shows that passageway  38  with at least one step  70  which may be used to seal the vibratory unit or the removable part securely in the passageway. Multiple steps may be used.  FIG. 1D  shows that passageway  38  is threaded. The steps may provide a tactile indication of plug/vibrator depth. 
     FIG. 1E  diagrammatically illustrates a one-way valve  50  in the passageway  38 . The valve and valve stem  50  may be similar to the one-way valve and valve stem used on beach balls and other common manually inflatable items. The common valve and valve stem  50  extends from the distal end of passage  38 . When cap  54  is withdrawn from the cap seat on the valve stem  56 , air may flow out of passageway  38  due to compression at suction cup end  32 ,  34 . The one way air valve  50  permits flow of air outbound from passage  38 . One way valve  50  is opened when radial compression is applied to stem region  56 , which compression opens valve  52  in the stem. Operationally, when the valve cap  54  is withdrawn from the valve stem seat, air may flow outboard of the passageway  38 , but not inward into the passageway due to the one-way action of valve  52 . When the cap is on the valve stem seat, air flow is generally prohibited. 
     FIG. 2  shows a front elevational view of stimulator  10  with cutout  50  in the base  30  and shows the location of exit opening  49  of passageway  38 . 
     FIG. 3  shows a rear view of stimulator  10 . 
     FIG. 4  is a top view showing stimulator  10  and generally round or oval rim  34  of suction element  32 . 
     FIG. 5  is a bottom view of stimulator  10  shown through passage  38 . 
   Stimulator  10  may be constructed of a rather rigid material such as hard plastic, rubber, or the like. However, it is preferable for stimulator  10  to be constructed of a more compressible or resilient material, such as soft plastic or a foam material, of the type that is capable of retaining its shape and rigidity during use, but which is not so un-bending or inflexible as to be uncomfortable. Silicone is a good material to use. Also, an outer continuous covering or coating which is both smooth and slippery over such material would further enhance the enjoyment of stimulator  10 . Preferably, stimulator  10  is a unitary item wherein the base, the first end region and the bulbous second end region are all one piece and all made of the same flexible resilient material. Finally, it is anticipated that the angles of the legs of the truncated U-shape, that is, the general angle between the phallic end and bulbous end, would be in the range of from 60 to 80 degrees, more or less, so as to provide the most comfort during use, however, such angle may be as sharp as 45 degrees or as great as 90 degrees in some instances. 
   Of course, the actual length and diameter of phallic end and bulbous end can vary as needed depending on the needs of the partners. In this fashion, it is anticipated that different sizes of these ends can be offered which correspond with different sizes of the suction element and the neck portion or region so that stimulator  10  can conform to the needs and comfort levels of the intended users. The base at the curved region of the truncated U-shape may be larger or smaller than shown in relation to the phallus end and the bulbous end. 
   The claims appended hereto are meant to cover modifications and changes within the scope and spirit of the present invention.
