TOILET
A toilet having the toilet seat thereof supported on the rim of the toilet bowl in a downwardly forwards extending sloping position for supporting the user in a half-squatting position such that 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.
(a) Field of the Invention
The present invention relates to toilets and more particularly to such a toilet of which the toilet seat defines with the horizontal line a 5°˜70° angle (preferably 7°˜12°) so that the user is sitting on the toilet seat at a half-squatting manner to facilitate discharging of waste matters from the bowels.
(b) Description of the Prior Art
According to researches, the rectum is empty most of the time. Because there is a functional constrictor of low tension in the junction between the rectum and the sigmoid colon, the muscles of the rectum are induced to make a reactive contraction and the sphincter muscle of the anus is relaxed during the motion of the digestive system to force waste matters out of the bowels into the rectum. Because consciousness controls the contraction of the internal and external sphincter muscles of the anus, waste matters do not leak out of the anus.
The action of discharging waste matters out of the bowels is a reactive action induced by the local intestine plexus. This reactive action is the so-called “Internal Reaction”, i.e., the plexus in the rectum wall is stretched to excite when waste matters enter the rectum, causing the descending colon, the sigmoid colon and the rectum to crawl and to push waste matters to the anus. When the crawling waves reach the anus, the intestine plexus gives a signal to the anus to relax the internal sphincter muscle of the anus, thereby discharging waste matters out of the anus.
Therefore, when conscious of discharging waste matters, the external sphincter muscle of the anus must be relaxed so that the muscles of the abdomen can apply a pressure to the rectum to force waste matters out of the anus. However, regular toilets include two types, i.e., a first type having a toilet seat and a second type without toilet seat. When using a toilet without a toilet seat, the user must sit on the heels or with the legs drawn up closely beneath the body when using a toilet without a toilet seat. Using a toilet without a toilet seat is uncomfortable. People may be unable to keep the body in a squatted position for long. An old person may be unable to stand up from a squatted position.
When using a toilet with a toilet seat, the user can sit on the toilet seat. Therefore, it is more comfortable to use a toilet having a toilet seat. When sitting on the toilet seat 110 of a toilet 100, as shown in
The present invention has been accomplished under the circumstances in view. According to one aspect of the present invention, the toilet comprises a toilet bowl and a toilet seat hinged to the toilet bowl and supported on the rim. The toilet seat is supported on the rim in a downwardly forwards extending sloping position at a sloping angle about 5°˜70° for supporting the user in a half-squatting position such that 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.
In one embodiment of the present invention, the rim of the toilet bowl slopes downwardly forwards at a sloping angle about 5°˜70°, thereby supporting the toilet seat in the downwardly forwards extending sloping position. In another embodiment of the present invention, the rim of the toilet bowl extends horizontally, and the toilet seat has a horizontal bottom wall supported on the rim and a downwardly forwards extending sloping top wall for a person to sit on.
According to still another aspect of the present invention, a toilet support is used with the toilet. The toilet support has a seat disposed above the elevation of the rim of the toilet bowl and sloping downwardly forwards at a sloping angle about 5°˜70°. The seat of the toilet support has a horizontally extending bottom wall and a downwardly forwards extending sloping top wall for a person to sit on.
According to still another aspect of the present invention, the toilet support has a plurality of vertical legs respectively fastened to the horizontally extending bottom wall bottom wall of the seat for positioning on the floor to support the seat above the elevation of the rim of the toilet bowl.
According to still another aspect of the present invention, the toilet support can be made in the form of a drop-arm commode, which has the seat thereof set in a downwardly forwards extending sloping position.
According to still another aspect of the present invention, the downwardly forwards extending sloping position of the toilet seat is preferably at a sloping angle about 7°˜12°.
According to still another aspect of the present invention, the toilet seat has a smoothly curved top surface fitting the shape of the hips of a person.
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
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.
