Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to the structure of a toilet seat of a Western style toilet bowl.

[Prior Art] In the conventional toilet seat of a Western-style toilet, the front portions of both sides of the toilet seat 1 on which the thighs of the human body rest are almost the same height as the other portions. As shown in FIG. 9, the cross-sectional shape was such that the central portion of the upper surface portion was substantially flat, and the corner portion formed by the central portion of the flat upper surface portion and the side surface was sharply bent.

[Problems to be Solved by the Invention] In the conventional example as described above, however, the outer corner portion of the front portion of the side portion of the toilet seat 1 on which the thigh of the human body rests is different from the other portions. Since it was not recessed, the thigh of the human body was partially pressed at this corner, and a comfortable feeling was not obtained.

The present invention was devised in view of the problems of the above-mentioned conventional example, and its purpose is to prevent partial compression of the thigh of the human body when sitting on the toilet seat. The purpose of the present invention is to provide a toilet seat structure that provides a comfortable feeling.

[Means for Solving the Problems] The structure of the toilet seat according to the present invention is such that the outer corners of the front portions of both sides of the toilet seat 1 on which the thighs of the human body rest are slightly lowered to place the thighs on the thigh. Forming the recessed portion 2 for the seat, the curvature of the upper surface of the seat of the toilet seat 1 is set to 1 / 0.0075 to 1 / 0.01 mm, and the curvature of the upper surface of the recessed portion 2 for thigh mounting is 1 / 0.008 to 1 / 0.012 mm By adopting such a configuration, the problems of the conventional example described above are solved.

[Operation] Then, by slightly lowering the outer corner portions of the front portions of the both sides of the toilet seat 1 on which the thighs of the human body are placed to form the thigh placement recesses 2, By placing the thigh in the thigh placing concave portion 2 slightly lowered, it was possible to prevent partial pressure on the thigh.

[Embodiments] The present invention will be described in detail below based on embodiments shown in the accompanying drawings.

FIG. 1 shows a perspective view of the toilet seat 1. The toilet seat 1 has an annular shape, and the front outer corner portions of both sides of the toilet seat 1 are slightly lowered as compared with the other outer side corner portions and the outer front corner portions. It is a thigh mounting recess 2. The thigh mounting recess 2 is continuous with the other part by a gentle curved surface. Then, as shown in FIG. 2, the thigh is placed in the thigh mounting recess 2 which is slightly recessed, and the thigh is released to eliminate the feeling of pressure on the thigh so that the thigh is comfortable to sit on. I am doing it. That is, since the thighs are lowered, the weight is distributed to the legs and the weight burden on the hips is reduced. A portion 3 of the rear part of the toilet seat 1 against which the rear part of the human body hits is formed so that the rear part of the rear part comes into close contact with the rear part of the human body to prevent water splashing when washing with warm water.

By the way, as shown in FIG. 3, the toilet seat 1 is inclined downward as a whole so that the rear side is higher and the front side is gradually lower, and the inclination gradient is 3 to 5 degrees. Inclining the toilet seat 1 as a whole forward and downward as described above extends the spine and reduces the burden on the lower back during use.

The cross-sectional shape of the above-mentioned thigh mounting concave portion 2 shown in FIG. 3 taken along the line EE has a cross-sectional shape as shown in FIG. 4, and its curvature is from 1 / 0.008 to 1 / 0.012
It is formed in mm.

In addition, the cross-sectional shape of the portion on which the bottom shown by the line roll in FIG. 3 is placed has the cross-sectional shape as shown in FIG. 5, and the curvature of the cross-sectional portion is formed to be 1 / 0.0075 to 1 / 0.01 mm. There is.

Here, FIG. 6 shows the experimental results showing the relationship between the inclination gradient of the seat surface of the toilet seat in FIG. 3 and the ease of sitting. Also,
FIG. 7 shows experimental results showing the relationship between the upper surface curvature of the portion on which the thigh is placed and which is indicated by the line EE in FIG. 3 and the fit of the thigh. Further, FIG. 8 shows the experimental results showing the relationship between the upper surface curvature of the portion where the hips are placed and which is indicated by the line roll in FIG. 3 and the fit of the hips.

As is clear from the results shown in FIGS. 6 to 8, the toilet seat 1
It was found that the degree of satisfaction can be obtained by setting the inclination gradient of 3 to 5 degrees. It was also found that the upper surface curvature of the part on which the thigh is placed has a degree of satisfaction of 1 / 0.008 to 1 / 0.012 mm. Furthermore, it was found that the degree of satisfaction can be obtained by forming the upper surface curvature of the portion where the hips are placed to 1 / 0.0075 to 1 / 0.01 mm.

[Advantages of the Invention] As described above, according to the present invention, the outer corners of the front portions of both sides of the toilet seat, which is the portion on which the thigh of the human body rests, are slightly lowered to allow the thigh placement recess. Since it was formed, by placing the thigh of the human body in the thigh mounting recess slightly lowered, it is possible to prevent partial pressure on the thigh,
A comfortable feeling is obtained, especially, the curvature of the upper surface of the buttocks of the toilet seat is 1 / 0.0075 to 1 / 0.01 mm, and the curvature of the upper surface of the thigh mounting recess is 1 / 0.008 to Since it is 1 / 0.012 mm, the experimental results of the relationship between the upper surface curvature of the portion on which the thigh is placed and the fit of the thigh shown in FIGS. 7 and 8 and the hip are placed. As is clear from the experimental result of the relationship between the upper surface curvature of the part and the fit of the hip, a satisfactory fit of the user's thigh or hip to the toilet seat can be obtained.
