Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stool-type simple toilet, and more particularly, to a simple toilet that can easily stand and sit.

[0002]

2. Description of the Related Art A ceramic flush toilet is made such that the front surface of the peripheral wall of the toilet body is located at a position retracted from the front of the toilet body including the toilet seat. Therefore, when the toilet user performs the standing and sitting operation, the leg can be placed in a state of being inclined slightly closer to the toilet main body side than the vertical position and can stand and sit in a natural state.

[0003] On the other hand, there is a portable stool which is called a portable toilet and is provided with a pot with a lid in a toilet body. Such a simple toilet is mainly made of a synthetic resin, and includes a toilet body a mainly composed of a trunk peripheral wall b, and a toilet seat c and a toilet lid d mounted on the upper part thereof as shown in FIG. ing.

[0004] In such a simple toilet, the trunk wall b is usually formed by injection molding, and the trunk wall b is a wall surface which is inclined outward from the upper end downward. The reason for this is that when the body wall is reversely inclined, the mold structure causes an undercut when the mold is opened, making molding impossible, and, like a Western-style flush toilet made of ceramics, Because it is not fixed to the floor, it is also preferable to incline the torso peripheral wall outwardly because the stability at the time of installation is improved.

[0005] However, in the case of the torso peripheral wall which is inclined so as to spread, since the foot comes forward of the toe of the torso peripheral wall, a perpendicular line passing through the grounding point A of the foot and the center of gravity G of the human body while sitting on the floor. When the distance D from C becomes long and the user stands and sits, excessive force or moment is applied to the legs and hips, and the muscles may be damaged. In particular, it is a great physical burden for a physically handicapped person, an elderly person, or a sick person who needs a simple toilet.

Accordingly, the applicant has disclosed in Japanese Patent Application Laid-Open No. 5-187049.
Proposed a toilet bowl as disclosed in Japanese Patent Application Laid-Open Publication No. H10-209,878. In this toilet, a recessed portion is provided on the front surface of the trunk peripheral wall of the toilet main body so as to be able to store a leg of a human body in a posture of sitting on the toilet main body. In this toilet, when the user is seated on the toilet, the legs can be put into the recessed portions, so that the standing and sitting operation is facilitated. In addition, by making the rear surface of the body peripheral wall largely inclined, it is possible to prevent an undercut from occurring when the mold is opened, and to solve a problem in molding.

However, in the toilet described in the above-mentioned Japanese Patent Application Laid-Open No. Hei 5-18749, the inclination and depth of the recessed portion are still limited due to molding reasons of avoiding undercut.
Therefore, the standing and sitting motions are still limited, so that they are not always satisfactory.

[0008]

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems of the prior art, and does not impose an unreasonable physical burden on the human body when the user stands and sits down, and furthermore, the under An object of the present invention is to provide a simple toilet bowl that eliminates restrictions on molding such as a need to eliminate cuts.
