Description

  The present invention relates to a seat-type toilet (Western-style toilet), and relates to a technique that allows a user to sit comfortably and use a toilet.

Conventionally, with regard to the functionality of a seat-type toilet (Western-style toilet), the main point of the toilet body is how to cleanly and efficiently flow the stool after use.
In addition, the toilet seat has a convex (mountain-shaped cross-section) bank shape so that the buttock can be comfortably seated, and in order to eliminate the cold feeling of the buttock when the user is seated, especially in winter. It is known that a heater or the like is attached to the toilet seat.

  Here, the shape of the toilet main body 51 that has been on the market has been designed based on the shape defined in the Japanese Industrial Standard (JIS-A5207-1995) as shown in FIG. 5 (a). The dimensions in JIS are length P = 470 mm, width Q = 355 mm, thigh region radius R = 343 mm, and front end 50 radius S = 120 mm.

  The toilet body 51 has an oval shape and is formed such that an intermediate point Q1 between the region 51a where the buttocks sit and the region 51b where the thigh sits has the maximum width Q as the center of the toilet body. The width Q in the region 51 b where the part is seated is a tapered shape over the front end part 50. And the toilet bowl width | variety of the area | region 51a where a buttocks sits is not defined in particular. As described above, according to the Japanese Industrial Standard, the front part of the toilet body 51 is particularly stipulated.

  As shown in FIG. 5 (b), the shape of the toilet body 51 in recent years is such that the front part of the toilet body 51 is shaped based on Japanese Industrial Standards, and the rear part can be washed without using paper after the toilet. From the standpoint of securing space for high functionality such as a washlet or from a design standpoint, there are many shapes that extend the width Q in parallel from the midpoint Q1 to the rear.

  As shown in FIG. 5C, the outer shape of the toilet seat 52 is formed in substantially the same manner as the outer shape of the toilet body 51. From the intermediate point T1 between the region 52a where the buttocks sit and the region 52b where the thigh is seated. The width T of the toilet seat is extended in parallel (end portion T2, end portion T3) up to the center 52a of the buttocks and the center of the toilet seat mounting hole. In the thigh region 52b, the shape is tapered from the intermediate point T1 to the vicinity of the front end portion 54.

  However, with this tapered shape, the seating area where the thigh contacts the toilet seat cannot be secured sufficiently, so that a sense of stability cannot be obtained, and the sitting comfort (hold feeling) is not comfortable, and the thigh is not comfortable. There was a problem that the feet became numb when sitting for a long time due to local load concentration.

  As means for solving this problem, it is conceivable to increase the area of the region where the thigh is in contact with the toilet seat.

As shown in FIG. 6 (Patent Document 1), although the subject is different from the present application, a configuration in which the width of the toilet seat 60 is made parallel to the entire area is disclosed in the figure. With this configuration, the seating area of the thigh is reduced. Can be wide.

  However, in the toilet seat of Patent Document 1, the seating area of the thigh can be increased. However, since the toilet seat has a flat plate structure, the region where the thigh is in contact with the toilet seat is unstable and the seating comfort is poor. There was a problem.

  Therefore, the present invention increases the width of the toilet seat, increases the seating area on which the thigh is seated, makes the toilet seat a shape corresponding to the outer shape of the thigh, and makes the thigh contact with the toilet seat An object of the present invention is to provide a seat-type toilet that can increase the stability by dispersing the load of the seat and improve the sitting comfort.

  The invention of claim 1 is a seat-type toilet comprising a toilet seat made up of a convex (cross-section) bank surrounding an oval opening in the center and a toilet body, and the outer shape of the toilet seat in plan view is The rear portion of the toilet seat as a region where the seat is seated is continuously widened from the rear end portion of the toilet seat to the substantially central portion of the toilet seat, and the front portion of the toilet seat as a region where the thigh is seated is substantially half The height of the convex bank is continuously curved into a curved shape so that the convex bank in the region where the thigh is seated substantially corresponds to the outer shape of the thigh. It is characterized by being formed.

  In this seat-type toilet, the rear part of the toilet seat is continuously widened from the rear end of the toilet seat to the substantially central part of the toilet seat, so that the area of the toilet seat in the region where the thigh is seated can be increased. Further, since the height of the convex bank is continuously curved and formed so as to correspond to the outer shape of the thigh, a toilet seat shape corresponding to the outer shape of the thigh can be formed. .

  The invention according to claim 2 is the seat-type toilet according to claim 1, wherein the convex bank in the region where the thigh is seated of the toilet seat is an outer slope than an inner slope of the toilet seat. The outer slope is formed so that the height of the slope is the lowest at a position where the thigh is away from the toilet seat.

  In this seat-type toilet, the toilet seat can have a shape corresponding to the outer shape of the thigh. Moreover, a slope can be formed naturally in the direction in which the thigh extends downward.

  The invention of claim 3 is the seat-type toilet according to claim 1 or 2, wherein the toilet main body is configured to hold a plurality of toilet seat legs provided in the vicinity of the outer peripheral end portion on the back side of the toilet seat. The shape of the toilet seat is substantially the same as that of the toilet seat in plan view.

  In this seat-type toilet, the width of the front part of the toilet body is wide and formed in a substantially circular shape.

  According to the invention of claim 1, the area where the thigh of the toilet seat is seated can be widened. Further, the toilet seat can have a shape corresponding to the outer shape of the thigh. For this reason, the load in the region where the thigh is in contact with the toilet seat can be dispersed, and the stability can be increased and the sitting comfort can be improved.

  According to the invention of claim 2, the toilet seat has a shape corresponding to the outer shape of the thigh, and the seating area can be increased. Moreover, a slope can be formed in the direction in which the thigh extends downward. For this reason, the stability of the region where the thigh is in contact with the toilet seat can be increased, and the load can be dispersed to improve the sitting comfort.

  According to invention of Claim 3, the front part of a toilet bowl main body is formed in a substantially circular shape, and the width | variety of a front part becomes wide. For this reason, the cleaning effect in the swirl cleaning with the cleaning water of the toilet body is improved. When urinating, the urine will not scatter due to its wide width.

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

<Composition of seat-type toilet>
As shown in FIGS. 1 and 2, a seat-type toilet 1 according to an embodiment of the present invention includes a toilet seat 5 including a convex (cross section) bank 4 surrounding a substantially elliptical opening 2 provided in a central region 2 and a toilet. The main body 6 is comprised.

  The outer shape of the toilet seat 5 in a plan view is such that the full width 10 of the toilet seat 5 continuously extends from the rear end 8 of the rear portion 7 of the toilet seat 5 including the region where the buttocks are seated to the central portion 9 of the toilet seat 5. The front portion 11 of the toilet seat 5 including the region 5b on which the thigh is seated is formed in a substantially semicircular shape having the entire width 10 of the central portion 9 of the toilet seat 5 as a diameter.

  In the convex bank 4 in the region 5b where the thigh is seated, the bank 4 (height H) is continuously curled into the curved surface shape M so as to correspond to the outer shape of the thigh. It is formed.

  The toilet seat 5 is fixed to the rear end portion 8 of the seat-type toilet 1 by a hinge portion 30 so as to be freely opened and closed. Further, the toilet lid 31 can be closed by the hinge portion 32 so as to cover the toilet seat 5 in the same manner.

  Here, since the width E of the rear end portion corresponds to the size of the user's buttocks, it is substantially the same width as the width T of the toilet seat of the conventional seat-type toilet described with reference to FIG. Further, since the substantially elliptical opening 2 in the central region 2 is required to have a size that allows the stool to be stably held in the toilet seat and the stool to pass stably, the shape and dimensions of the opening 2 are the same as those of the conventional area. It is almost equivalent to the shape.

  From this, the toilet seat 5 in the embodiment of the present invention has the full width 10 of the toilet seat 5 continuously expanding from the rear end portion 8 to the central portion 9 of the toilet seat 5, so that the front of the toilet seat 5 is compared with the conventional toilet seat. Since the both ends of the part 11 protrude, the area of the region 5b where the thigh is seated can be increased.

  The outer peripheral part of the front part of the toilet seat is formed in a substantially semicircular shape, but the shape of the toilet body is also adjusted so that a plurality of toilet seat legs 34 provided near the outer peripheral end part on the back side of the toilet seat can be held in accordance with this shape. The outer shape of the toilet seat is substantially the same.

  As shown in FIGS. 3A and 3B, the planar shape of the toilet seat 5 is, for example, the width E = approximately 355 mm of the rear end 8, the entire width F = approximately 390 mm, and the entire length (based on the toilet seat mounting hole center). G = approximately 440 mm, the lateral width E1 of the approximately elliptical (egg-shaped) opening 2 = approximately 205 mm, and the total length G1 = approximately 315 mm.

  The toilet seat 5 is formed by surrounding a convex bank 4 around a substantially elliptical (egg-shaped) opening 2 so that the convex bank 4 can stably and comfortably hold the thigh of the user. The curved surface M is formed.

  Now, the curved surface of the surface of the toilet seat 5 will be described with reference to five curves 21, 22, 23, 24, 25 surrounding the opening 2. A curved line 21 is an inner contour line of the toilet seat 5, and a curved line 25 is an outer contour line of the toilet seat 5. Curves 22, 23, and 24 are ridge lines of the convex bank 4 (ridge lines, not contour lines).

  Here, in the region 5a where the buttocks are seated, the curve 23 spreads in the width direction of the toilet seat 5, so the length between the curves 21 and 23 is the distance K1 in the width direction from the length K2 in the length direction. Also long. For this reason, a gently curved slope is formed in the width direction corresponding to the shape of the flange.

  In the region 5b in which the thigh is seated, from the center point 20 of the egg-shaped opening 2 (here, centered on the vicinity where the lateral width E1 is the maximum width), approximately α = approximately 40 in the front direction. If a straight line of a degree is drawn and the intersections intersecting with the curves 22, 23, 24 on this straight line are points 26, 27, 28, the distance K3 between the points 26, 27 is shorter than the distance K4 between the points 27, 28.

  For this reason, the convex bank 4 in the region 5b where the thigh is seated is formed such that the slope on the outer side (near K3) of the toilet seat 5 is smoother than the slope on the inner side (near K3).

  In the vicinity of the point 27 where the thigh is seated on the toilet seat 5, the height of the curve 23 as the ridgeline of the convex bank 4 is formed to be the lowest. Then, at the point 28 of the curve 24 as the position where the thigh is separated from the toilet seat 5, the slope height H is formed to be the minimum height.

  Here, between the curves 21 and 22 and between the curves 23 and 24 is for chamfering of the rising as the convex bank 4 on the inside and outside of the toilet seat 5, respectively, and the user's buttocks and thighs are substantially Never sit down.

<Effects of sitting toilet>
As described above, the shape of the toilet seat in plan view is formed in a substantially semicircular shape in which the full width continuously expands from the rear end portion to the central portion, and the front portion has the full width of the central portion of the toilet seat as a diameter. Furthermore, the convex bank in the region where the thigh is seated is formed in a curved surface corresponding to the outer shape of the thigh.

  As for the shape of the curved surface, a region near the point 27 which is a position where the toilet seat 5 is seated as the approximate center of the thigh is formed so that the height of the curve 23 as the ridgeline of the convex bank 4 is the lowest. The convex bank is formed such that the outer slope is gently formed from the inner slope, and the slope height H is the minimum height at the point 28 where the thigh is separated from the toilet seat 5. The

  Therefore, as shown in FIG. 4, when sitting on the toilet seat, the area in which the thigh in the natural state is seated increases (increase region 16), and a curved surface is formed corresponding to the outer shape of the thigh. Therefore, the feeling of fatigue when sitting on the toilet seat can be reduced.

  According to the experiment, the surface pressure in the center region 15 of the thigh, which is considered to feel the most fatigue, can be reduced by about 25% compared to the conventional product.

  Conventionally, since the region where the thigh is seated was small, the heating effect was not obtained so much. However, according to the present invention, the increased region 16 (in the outer peripheral portion of the front portion of the toilet seat where the thigh is seated) Heating heaters can be added to a region that increases compared to conventional toilet seats), so that the region where the thigh is seated can be heated over a wide area, and an efficient heating effect can be obtained.

  In addition, as described with reference to FIG. 2, the outer peripheral portion of the front part of the toilet seat where the region where the thigh is seated increases is formed in a substantially semicircular shape. In accordance with this shape, when the shape of the toilet body is formed to be substantially the same as the outer shape of the toilet seat so as to hold a plurality of toilet seat legs 34 provided in the vicinity of the outer peripheral end portion on the back side of the toilet seat, The portion 11 has a substantially circular shape in plan view.

  For this reason, the flushing water of the toilet becomes easy to turn, and the cleaning effect of the bowl surface of the toilet is improved. Moreover, since the front opening of the toilet body is wide, it does not scatter during urination, so it is hygienic.

  As mentioned above, although embodiment of this invention was described based on drawing, all said Example showed an example of this invention, and it cannot be overemphasized that this invention should not be limited to these. Absent.

  For example, the toilet seat is formed of a convex (mountain-shaped cross section) bank surrounding the substantially elliptical opening, but it does not necessarily have to be a donut-shaped toilet seat with a continuous entire circumference. It may be a toilet seat.

It is a perspective view of the seat type toilet bowl in the embodiment of the present invention. It is a side view of the seat type toilet bowl in the embodiment of the present invention.
