Abstract

PURPOSE: To provide a stable feeling of sitting with no drop of buttocks by supporting body weight just under an ischicadic tuber by providing buttocks supporting planes for supporting the ischiadic tuber on a sitting plane just under it on the toilet seat. CONSTITUTION: This toilet seat 1 is composed of a main body 2 of the toilet seat provided with buttocks supporting planes 4 for supporting an ischiadic tuber on a sitting plane just under it, and an inner edge 5 of the toilet seat is elliptically formed whose longer diameter is longer than that of a conventional toilet seat. By the existence of these buttocks supporting planes 4, most of the weight loaded to the buttocks can be supported just under the ischiadic tuber, and a stable feeling of sitting with no drop of the buttocks can be obtained. Besides, since the toilet seat is formed with a little gradient and a smooth curvature so as not to partially eccentrically support the femurs and shaped to support the femurs by extending the internal edge, sitting pressure at the parts in contact with these femurs is diffused and the circulation of the blood at the femurs is not disturbed. Further, the rear end of the toilet seat is made higher than the front end so that the angle of the pelvis can not be rotated back more than needed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a toilet seat having a shape capable of supporting the body weight just under the ischial tuberosity and reducing the pressure which is a factor inhibiting blood circulation in the thigh in order to improve the sitting comfort. is there.

[0002]

2. Description of the Related Art In recent years, the proportion of the elderly population has increased remarkably,
It is desired to develop a device for improving daily activities. Of these, defecation and bathing are particularly heavy and frequent. Regarding toilet seats, in addition to the toilet seat with heating function and the toilet seat with cleaning function which have already been popular, various products have been announced for this purpose. A typical example thereof is disclosed in Japanese Patent Laid-Open No. 62-275422. This is because an elderly person or the like can easily sit up and down on the toilet seat by configuring the toilet seat with a support body that can move up and down with respect to the toilet bowl and a hydraulic cylinder rotating toilet seat body that can be placed on the support body. In addition, JP-A-4-338
Japanese Patent No. 430 discloses that a toilet seat having a comfortable sitting comfort can be provided by forming a molding layer having rubber elasticity and a molding layer having rigidity at low pressure on the surface of the toilet seat.

[0003]

However, in the conventional toilet seat, a local force acts on the human body due to the shape of the toilet seat,
There was a problem that I got tired when I was sitting for a long time. In particular, elderly people tend to have a long stool time, and for the coming aging society, it is desired to have a comfortable seat and a seat that does not get tired even after sitting for a long time. The above-mentioned conventional examples relate to movable up and down, elastic materials, and the like, and neither mentions consideration of sitting comfort due to the shape of the toilet seat itself. In addition, the durability of movable and elastic materials is questionable, and the cost is considerably high. The present invention solves the above problems, and a first object of the present invention is to provide a toilet seat having a better sitting comfort.

The second purpose is not to disturb the blood circulation in the thigh.

[0005]

In order to achieve the first object of the present invention, the inner edge of the toilet seat has a shape capable of having a weight-bearing surface capable of supporting the ischial tuberosity on the seat surface immediately below.

In order to achieve the second object, a shape of a gentle curvature with a small inclination without partial biased support of the thigh and a shape of a thigh support with an extended inner edge having a seat pressure diffusion effect are provided. It became the composition.

Further, the mounting surface of the toilet bowl to which the toilet seat is attached is horizontal, and the height from here to the toilet seat surface is different between the front and the rear, and the rear end is higher than the front end.

Further, the front end of the toilet seat is provided with a convex shape that promotes the opening of the crotch joint.

[0009]

The present invention has the following effects due to the above-mentioned structure.

That is, the shape of the inner edge of the toilet seat, which can have a weight supporting surface just below the ischial node, can support most of the weight of the buttocks on the toilet seat surface directly below the same point.

The shape of the thigh with a gentle curvature with no partial uneven support and a small slope, and the shape of the thigh support with an extended inner edge diffuse the seat pressure at the portion where the same contact, and Does not interfere with blood circulation.

Further, since the rear end of the toilet seat is higher than the front end of the toilet seat, the pelvis angle is not rotated backward more than necessary.

The convex shape of the front end of the toilet seat promotes the opening of the crotch joint.

[0014]

Embodiments of the present invention will be described below with reference to FIGS.

(Embodiment 1) FIG. 1A is a plan view of a toilet seat body. The toilet seat 1 comprises a toilet seat body 2 having a buttocks support surface 4 capable of supporting the ischial tuberosity on the seat surface directly below. The shape of the inner edge of the toilet seat is shown in comparison with the conventionally used toilet seat. The inner edge 5 of the toilet seat of this embodiment is elliptic than the inner edge 6 of the conventional toilet seat. As a result, the dimension m becomes shorter than the dimension n. In this embodiment, m = 177 mm and n = 200 mm. Figure 1 (b)
[FIG. 3] is a cross-sectional view at the position AA shown in the above plan view. Since the inner edge has an elliptical shape as compared with the conventional one, the seating surface also becomes wider, and the cross-sectional width dimension p becomes longer than the conventional same dimension q. In this embodiment, p = 116 mm and q = 106 mm.

The operation and effect of the above structure will be described. In FIG. 1A, the human body outline 7 is the standard sitting position. As shown in the ischial tuberous position 3, the buttocks supporting surface 4 supports most of the weight of the buttocks on the surface directly below the ischial tuberosity point, so that a stable seating feeling can be obtained without the buttocks falling.

(Second Embodiment) FIG. 2A is a plan view of a second embodiment of the present invention. FIG. 2B shows a comparison of the cross section of the thigh support surface 8 taken along the line BB with the conventional toilet seat body 9. The cross-sectional shape of the same-portion support surface in the present embodiment has a gentle curvature with a small slope so as to follow the outer contour of the thigh when seated. Therefore, the dimension m is smaller than the dimension n. In this embodiment, m = 15 mm and n = 24 mm. As a result, the seat pressure of the portion where the parts come into contact is diffused, and blood circulation is not impeded, so that the legs do not get tired even after sitting for a long time.

(Embodiment 3) FIG. 3A is a plan view of Embodiment 3 of the present invention. The cross section at the C-C position is shown in FIG.
FIG. 3 shows a cross section of the conventional toilet seat body 9 at the same position.
It shows in (C).

This embodiment differs from the other embodiments in that the height from the toilet seat mounting surface to the toilet seat surface differs between the front and the rear and the rear end is higher than the front end. Further, the difference in height between the front and rear, that is, the difference between the dimension m and the dimension n shown in FIG. 3B is the same as that of the conventional toilet seat, that is, FIG. 3C.
It is larger than the difference between the dimension p and the dimension q shown in.
In this embodiment, m = 15 mm, n = 32 mm, p = 24 mm, q
= 32 mm.

Thus, when seated, the pelvis angle is not rotated backward more than necessary, and an excessive load is not applied to the waist.

(Embodiment 4) The construction of Embodiment 4 of the present invention is shown in FIG. It differs from the other embodiments in that a convex shape 10 is provided at the front end of the toilet seat. As a result, when sitting, the legs of the crotch joint can be promoted to smoothly move to the excretion posture during sitting.

[0022]

As is apparent from the above embodiments, according to the present invention, the following effects can be obtained.

(1) Since the surface just below the ischial tuberosity node supports most of the weight of the buttocks, a stable seating feeling can be obtained without the buttocks falling.

(2) The shape of the thigh with a gentle curvature with no partial uneven support and the gentle curvature of the thigh and the shape of the thigh with the inner edge extended diffuses the seat pressure of the same part and does not impede blood circulation. Therefore, there is an effect that legs do not become numb even when sitting for a long time. (3) The configuration in which the rear end is higher than the front end of the toilet seat does not rotate the pelvis angle rearward more than necessary and does not place an excessive burden on the lower back.

(4) Since the convex shape of the front end of the toilet seat promotes the leg opening of the crotch joint, it can be smoothly introduced into the excretory posture when sitting.
