Description:
FIELD OF THE INVENTION 
   The present invention relates to a sex aid device for assisting a human male and female couple to engage in sexual intercourse. 
   BACKGROUND OF THE INVENTION 
   It is believed that sex intercourse, and other types of sexual activity, are among factors for improving close relationship between a human male and female couple. The performance of the sexual act requires the male a certain amount of strength and mobility of the lower part of the trunk. For a man without the necessary degree of strength and mobility, it would be difficult to perform the sexual act. 
   For those who are handicapped or otherwise physically weak, it would be desirable for them to utilize sex aid devices to compensate their physical deficiencies. 
   SUMMARY OF THE INVENTION 
   It is an object of the present invention to assist the handicapped, especially for those who lose limb(s), to engage in sexual intercourse. 
   It is a further object of the present invention to alleviate the burden of physical strength in sexual activity, particularly, for those who are aged, infirm or corpulent. 
   According to the present invention, a sex aid device comprises a frame and at least one resilient member mounted on the frame in a fixed or removable manner. The frame has a leg portion and a support portion. The frame allows the male to lie down beneath the support portion without being hindered by the leg portion. The at least one resilient member each has its ends attached to the support portion for providing a seat for the female above the male lying down beneath the support portion. The at least one resilient member also defines at least one opening allowing genitals of the female seated on the at least one resilient member to be accessed by the genitals of the male lying therebeneath. 
   In use, the female seated on the at least one resilient member may proceed up-and-down or 360-degree rotational movement during the sexual activity while supported by the at least one resilient member, thereby facilitating control of body action or alleviate burden of physical strength. According to the invention, the device can support most of the female&#39;s weight so that the male need not to bear the full weight of the female and also assist her to attain desired actions during the sex activity. 
   The invention, together with the advantages thereof, may best be understood by reference to the following description taken in connection with the accompanying drawings.

   DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
   Referring to  FIG. 1 , there is depicted a sex aid device constructed in accordance with the present invention and designated as  10 . The sex aid device comprises a one-piece frame  16  and two spaced apart resilient belts  12  attached to the frame  16 . 
   The frame  16  includes a leg portion  16   a  and a support portion  16   b  integrated with the leg portion. The leg portion  16   a  comprises a pair of substantially U-shaped upright legs  17  and the support portion  16   b  comprises a pair of substantially parallel, transverse rods  18  disposed in an exclusively transverse direction relative the leg portion  16   b . According to the preferred embodiment, the leg portion and the support portion are integrally formed so that the frame  16  is a one-piece element. The frame can be made of iron or steel or synthetic material, as long as such material is capable of supporting the users during vigorous sexual activity. 
   Each end of the resilient belts  12  is wrapped around the rods  18  and fixed by rivets  14 . Alternatively, belts  12  may be attached to the rods by screw and nut arrangement or sewing (not shown). As shown in  FIG. 1 , the two spaced apart belts  12  are parallel to each other, defining an opening  15  therebetween. Two non-resilient bands  13  are tied to resilient belts  12  to limit relative transverse movement between the belts, so as to prevent the belts from being further displaced away from each other. The resilient belts  12  can be made of any resilient material, e.g. rubber or synthetic material, as long as such material is capable of providing enough resilience and flexibility and sufficient strength to support the users during vigorous sexual activity. 
     FIG. 2  shows an alternative embodiment  20  of a sex aid device according to the invention, which is similar to that of  FIG. 1 , except that a single piece of resilient cloth  22  with a central opening  24  thereon is attached to the frame  16 . 
     FIGS. 3 &amp; 4  illustrate a method of using the device  10  according to the invention. A person M, preferably a man, lies supine on a surface, such as a bed or the floor. He places the device across the lower portion of his trunk, centered roughly above his sexual organ. A person W, preferably a woman, is seated on the resilient belts  12  with her thighs supported by the belts. Thus, the couple can engage in sexual intercourse in a “female-up and male-down” manner. It should be noted that the resilient belts  12  are adapted to not only sufficiently bear the woman&#39;s weight without exerting excessive pressure on the man&#39;s trunk, but also keep close sexual intercourse between them during sexual activity. Since the man does not bear any (or just little) weight of the woman, uncomfortable feelings, such as numb legs or pains can be avoided for him. Moreover, due to the resiliency and three-dimensional degrees of freedom of movement of the resilient belts  12 , the woman seated thereon thus can move in each direction, e.g. up-and-down, left-and-right, front-and-back and rotation of complete 360 degrees. 
   In addition, due to the differences in individual user&#39;s height and weight, the required motion amplitude of the resilient belts  12  during sexual activity may be different. Therefore, resilient belts of different sizes may be provided so as to allow the users to attain a suitable angle, depth and motion pattern during sexual act. 
   It is possible that a user may wish to replace old resilient belts with new ones or ones of different size. Therefore, a further embodiment of a device according to the invention is shown in  FIG. 5 , wherein a device  30  comprises an integral frame  16 , two resilient belts  12  and two bands  13 , as those shown in  FIG. 1 . However, each resilient belt  12  has its both ends attached to a buckle  32 , as shown in  FIGS. 6 and 7 , which is conventionally known and comprised of portions  30   a ,  30   b  and  30   c  and an opening  32   a . The belt  12  may be removably attached to the frame  16  by the users as follows: the belt  12  with its ends having being attached to the portion  30   b  of the buckle  32  in factory has each end wrapped around the rod  18  and then inserted through a gap between the portions  30   a  and  30   b  via the opening  32   a.    
     FIG. 8  illustrates a further embodiment of a sex aid device according to the invention, wherein a device  40  comprises a frame  42  and resilient belts  12 . The frame  42  comprises a horizontally disposed U-shaped leg  44  and a support portion. The U-shaped leg  44  has a base  49  and open ends  47 . The support portion comprises a substantially T-shaped rod  48  extending upward from the base  49  and an inverted U-shaped rod  46  extending upward from the open ends  47  of the U-shaped leg  44 . Resilient belts  12  can be mounted between the T-shaped rod  48  and the inverted U-shaped rod  46 . In this case, a person may lie supine beneath the frame with the rod  46  toward his or her head. 
     FIG. 9  illustrates a further embodiment of a sex aid device according to the invention, wherein a device  50  comprises a detachable frame  86  and resilient belts  12 . The frame comprises legs  87  and rods  88  removably connected to the legs  87  through sleeve-like couplers  52 . As shown in  FIG. 10 , each end of the rods  88  has outer threads  89  and the legs  87  each has an enlarged end  90 . The coupler  52  has at one end internal threads engageable with the outer threads of the rod  88  and at the other end an opening  53  smaller than the enlarged end  90  and configured to prevent the coupler  52  from separating from the leg  87 . Thus, it is advantageous that through the couplers  52 , rods  88  and legs  87  can be disconnected for the purpose of replacing old belts  12  or storing the device  50 . 
     FIGS. 11 and 12  illustrate that a rigid plate  62  may be removably fitted on the rods  18  of the device  10  of  FIG. 1  so that the device  10  may serve as a table or chair with the plate  62  overlaying the belts  12 . As shown in  FIGS. 11 &amp; 12 , four snap-in clips  64  are provided on four corners of the bottom side of the plate  62  for clipping on the rods  18 . By means of such snap-in clips  64 , the plate  62  can be removably mounted on rods  18 . Alternatively, a piece of soft, non-resilient rectangular cloth  72  may substitute for the rigid plate  62 , as shown in  FIG. 13 . The cloth  72  is provided with a plurality of ring fastener  76  along two sides parallel to the rods  18  so that the cloth  72  can be attached to the rods  18  by strings  74  passing through the ring fasteners  76  and tied to the rods  18  with the cloth  72  overlaying the belts  12 . 
   While several embodiments of the invention have been shown and described, it will be obvious to those skilled in the art that changes and modifications may be made without departing from the invention in its broader aspects. Accordingly, the present invention is to be limited solely to the scope of the appended claims.
