DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

In the following described various embodiments of the present invention, the user keeps the body in a half-squatting position when sitting on the toilet seat, and the angle defined between the femur and the tibia is greater than 90-degrees. At this time, the muscles of the abdomen and the anus and the muscles around the bottom side of the pelvis are relaxed, and the user can easily apply a pressure to force waste matters out of the rectum and the anus to the outside of the body.

Referring to FIG. 1, the toilet, referenced by 300, comprises a toilet bowl 310, a tank 330 at the rear side above the toilet bowl 310, a toilet seat 350 hinged to the toilet bowl 310 and rested on the rim 311 of the toilet bowl 310, and a lid cover 370 hinged to the rear side of the toilet seat 350. The tank 330 may be formed integral with a part of the toilet bowl 310. Alternatively, the tank 330 may be separately installed. The tank 330 is adapted to hold water and to discharge water into the toilet bowl 310 to clean the toilet bowl 310 with a sudden rush of water. The rim 311 of the toilet bowl 310 slopes downwardly forwards at an angle about 5°˜70°, preferably at about 7°˜12°. Because the toilet seat 350 is supported on the rim 311, it is held in a sloping position. When sitting on the toilet seat 350, the user's body is kept in a half-squatting position, and the angle defined between the femur and the tibia is greater than 90°.

Further, the front edge a of the rim 311 of the toilet bowl 310 is spaced above the floor 390 at a distance greater than the length of the calf of an adult. To an adult, the length of the calf between the foot and the knee is about 0.285 of the body height. The average length of the calves of human beings is about 45 cm. Therefore, it is preferably to keep the front edge a of the rim 311 of the toilet bowl 310 spaced above the floor 390 at about 45 cm. Thus, when an adult is sitting on the toilet seat 350 of the toilet 300 above the rim 311 of the toilet bowl 310, the body is kept in a half-squatting position. At this time, the muscles of the abdomen and the anus and the muscles around the bottom side of the pelvis are relaxed, and the user can easily apply a pressure to force waste matters out of the rectum and the anus to the inside of the toilet bowl 310.

Further, the toilet seat 350 has a curved top surface 351 that fits the shape of the hips, allowing the user to sit comfortably. The lid cover 370 is hinged to the rear side of the toilet seat 350. When the lid cover 370 is closed on the toilet seat 350, the toilet seat 350 and the lid cover 370 block the top opening (not shown) of the toilet bowl 310, preventing external matters from falling into the toilet bowl 310.

FIG. 2 shows another form of the present invention. According to this embodiment, the toilet seat 710 is supported on the horizontal rim of the toilet bowl of the toilet 700, having a sloping top wall 711 for allowing the user to sit on. The sloping top wall 711 slopes downwardly forwards at an angle about 5°˜70°, preferably at about 7°˜12°. Further, the sloping top wall 711 has a smoothly curved surface that supports the user's hips comfortably. When sitting on the sloping top wall 711 of the toilet seat 710, the body of the user is kept in a half-squatting position. At this time, the muscles of the abdomen and the anus and the muscles around the bottom side of the pelvis of the user are relaxed, therefore the user can easily apply a pressure to force waste matters out of the rectum and the anus to the inside of the toilet bowl of the toilet 700. According to this embodiment, the toilet seat 710 has a horizontal bottom wall fitting the horizontally extending rim of the toilet bowl of the toilet 700. Alternatively, the toilet seat can be made having bottom pegs that support the toilet seat on the rim of the toilet bowl of the toilet in a sloping position.

FIG. 3 shows a toilet support 510 for use with a toilet 500 according to the present invention. The toilet support 510 has a horizontal bottom wall 511 attached to or facing the rim 501 of the toilet 500, and a sloping top wall 513 sloping downwardly forwards for the user to sit on. The sloping top wall 513 defines with the horizontal bottom wall 511 an angle about 5°˜70°, preferably about 7°˜12°. Further, the sloping top wall 513 has a curved surface fitting the shape of the hips of a human being. The toilet support 510 further has a plurality of legs 515 perpendicularly downwardly extended from the horizontal bottom wall 511 for supporting the toilet support 510 on the floor above the rim 501 of the toilet bowl of the toilet 500.

Referring to FIG. 4, the toilet support 510a has short front legs 515b and long rear legs 515a, and a seat 513a supported on the short front legs 515b and the long rear legs 515a in a downwardly forwards sloping position. The sloping angle of the seat 513a is designed to be at about 5°˜70°, preferably about 7°˜12°. Further, the legs of the toilet support may be made retractable and extendable.

FIGS. 5-7 show different forms of toilet according to the present invention. These toilets 300, 700 and 500 have different shape designs, holding the respective toilet seats 311, 711 and 513 at different sloping angles. When sitting on the toilet seat 311, 711 or 513, the user keeps the body in a half-squatting position. In this half-squatting position, the vertical distance between the front edge a of the toilet seat 311, 711 or 513 and the floor is greater than the length of the calf.

A prototype of toilet has been constructed with the features of FIGS. 1-7. The toilet functions smoothly to provide all of the features discussed earlier.

Although particular embodiments of the invention have been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the invention. Accordingly, the invention is not to be limited except as by the appended claims.
