As shown in the end views of FIG. 3A to FIG. 3E and FIG. 4A to FIG. side wall portions 412, 422, 432 that stand up, top surface portions 414, 424, 434 formed across both inner and outer peripheral side wall portions 412, 422, 432; , 434 and curved surface portions 413, 423, 433 having a constant radius of curvature. The entire toilet seat including the rear part 44 and the hinge part 45 is similarly configured to have a bottom part, a side wall part, a top part, and a curved part. Below, except when explaining specific parts among the large curvature part 41, the intermediate part 42, and the side parts 43, the bottom part of the entire toilet seat will be collectively referred to as the bottom part 401, the side wall parts as the whole will be collectively referred to as the bottom part 401, the side wall part 402, The curved surface portions are collectively referred to as a curved surface portion 403, and the top surface portions are collectively referred to as a top surface portion 404.

The boundary positions between the curved surface portion 403, the side wall portion 402, and the top surface portion 404 are positions where the curvature of the curved surface portion 403 changes on both the inner and outer peripheral sides. The end of each part exists at the boundary position.

As shown in FIGS. 3B to 3E, the large curvature portion 41 and the intermediate portion 42 have sloped surface portions 415, 425 that slope downward to the outer peripheral end in the top surface portions 414, 424. The outer peripheral end means the boundary between the top surface portions 414, 424 and the curved surface portions 413, 423. Since both the large curvature section 41 and the intermediate section 42 are sloped downward to the outer peripheral edge, it is possible to reduce the restraint on the user's body when sitting and to reduce the feeling of pressure on the legs from the toilet seat. Improves comfort.

Both the large curvature portion 41 and the intermediate portion 42 only need to have sloped surface portions 415, 425 that slope downward to the outer periphery, and the top surface portions 414, 424 need to slope monotonically downward from the inner periphery to the outer periphery. There isn't. In consideration of stability when the user is seated, the shape may be such that, for example, the midpoint of a straight line connecting the inner periphery and the outer periphery is the highest. In this embodiment, the top surface portions 414, 424 have inclined surface portions 415, 425 that slope downward from the center to the outer peripheral edge.

3A to 3E show the vertical height of the seat surface, and FIGS. 4A to 4E show the width W and inclination angle of the seat surface. In the present disclosure, the seat surface of the toilet seat 4 means a portion consisting of the top surface portion 404 and the curved surface portion 403.

Points O to R shown in FIGS. 3A to 3E and 4A to 4E indicate the following positions. A subscript character indicates that it pertains to the end face of the corresponding character. For example, point _OA represents point O on the AA' end face of straight line AA'.
Point O...In the end view of the toilet seat 4, the midpoint position of the width W1 of the toilet seat 4 in the top surface part 404.Point P...In the end view of the toilet seat 4, the outer peripheral edge position of the top surface part 404.Point Q...In the end view of the toilet seat 4, Lower end position of the curved surface part 403 on the inner peripheral side of the toilet seat 4 Point R... In the end view of the toilet seat 4, the lower end position of the curved surface part 403 on the outer peripheral side of the toilet seat 4

In FIGS. 3A to 3E, A1 to E1 each represent the height from the bottom surface portion 401 of the toilet seat 4 to the point O. A2 to E2 each represent the height from the lower of point Q and point R to point P. A3 to E3 each represent the height from whichever is lower of point Q and point R to point O.

In FIGS. 4A to 4E, W _A to W _E represent the width W of the seat surface corresponding to each end surface. The width W of the seat surface means the straight-line distance W between the point Q and the point R shown in FIGS. 4A to 4E. The inclination angles θ _A to θ _E of the seat surface are the inclination angles of the inclined surface portions 415, 425, and 435, and represent the angles formed between the straight line OP and the horizontal line.

The large curvature portion 41 of the toilet seat 4 according to the present embodiment shown in FIGS. 3B to 3D has a small height difference between points O and P, and is configured in a substantially planar shape. By reducing the height difference in the top surface portion 414, the stability of the user's seated state is improved, and the pressure applied to the body, such as the thighs, is dispersed, resulting in improved sitting comfort. Specifically, it is preferable that the difference in height between point O and point P is 5 mm or less.

The height of the outer peripheral end of the top surface portion 404 of the toilet seat 4 from the bottom surface portion 401 gradually decreases from the large curvature portion 41 toward the intermediate portion 42. The heights from the bottom of points P _B , P _C , and P _D , which are the outer peripheral ends of the BB' end face, CC' end face, and DD' end face of the large curvature part 41, are the outer circumference of the intermediate part 42. It is higher than the point _PE which is the edge. By forming the outer circumferential edge of the intermediate portion 42 to be lower than the outer circumferential edge related to the BB′ end surface of the large curvature portion 41, when the user stands up from a seated state, there is no resistance in front of the toilet seat, and the user can stand up smoothly. can. The height of the outer peripheral edge of the intermediate portion 42 is preferably the lowest among the heights of the outer peripheral edge of the toilet seat 4 as a whole.

The large curvature portion 41 has a portion in which the width W of the seat surface is larger than the width of the seat surface of the side portion 43 . For example, the width W _C of the seat surface on the CC' end surface is wider than the width W _A of the seat surface on the AA' end surface of the side portion. This increases the area that supports the user's thighs and improves stability when sitting, providing a sense of security and improving sitting comfort.

The inclination angle of the inclined surface portion 425 in the intermediate portion 42 is larger than the inclination angle of the inclined surface portion 415 in the large curvature portion 41 . This reduces the contact area between the toilet seat 4 and toilet lid 12 when they are opened and closed at the same time, improving sliding performance.

This will be explained in detail below. As shown in FIG. 5, the toilet lid 12 has a buffer portion 121 on the surface on the toilet seat 4 side. When opening and closing the toilet seat 4 and the toilet lid 12, the intermediate portion 42 of the toilet seat 4 collides with the buffer portion 121 due to the force of opening and closing. The buffer portion 121 is formed for the purpose of buffering the collision between the intermediate portion 42 and the buffer portion 121, and is therefore made of an elastic body such as rubber.

Since the positions of the rotation axes of the toilet seat 4 and the toilet lid 12 are different when they are opened and closed, their relative positions change between when they are opened and when they are closed (see FIGS. 5 and 6). Therefore, when opening and closing both at the same time, sliding may occur between the intermediate section 42 and the buffer section 121 along with the opening and closing operations. If the sliding properties of the two are poor, there is a risk that the toilet seat 4 and the toilet lid 12 may be damaged or that opening and closing may become difficult. In this embodiment, the distal end of the intermediate section 42 is inclined downward toward the outer circumferential direction, thereby improving the slidability between the intermediate section 42 and the buffer section 121, thereby preventing the occurrence of scratches and hindrance to opening/closing. be able to.

It is preferable that the toilet seat 4 has at least one leg portion 46 on the back surface that comes into contact with the toilet bowl 15 when the toilet seat 4 is in a lowered state. The legs 46 are made of an elastic body such as rubber, so that they can buffer collisions with the toilet bowl 15 when the toilet seat 4 is opened and closed.

The toilet seat 4 according to an embodiment of the present disclosure has been described above. According to the toilet seat 4, the following effects are achieved.

The toilet seat 4 of this embodiment has, on the front side, a pair of large curvature parts 41 whose outer periphery has the maximum curvature, and an intermediate part 42 interposed between the pair of large curvature parts 41. 41 and the intermediate portion 42 both have inclined surface portions 415 and 425 that slope downward to the outer peripheral end. Thereby, it is possible to reduce the restraint on the user's body when sitting, and also to reduce the feeling of pressure on the legs from the toilet seat 4, improving the comfort of sitting.

The large curvature portion 41 is configured to have a substantially planar shape. This improves the stability of the user's seated state, and also disperses the pressure applied to the user's body, such as the thighs, thereby improving sitting comfort.

The large curvature portion 41 and the intermediate portion 42 are formed across the bottom portions 411, 421, a pair of side wall portions 412, 422 rising along the inner and outer peripheries of the bottom portions 411, 421, and the pair of side wall portions 412, 422. and curved surface portions 413, 423 interposed between the pair of side wall portions 412, 422 and the top surface portions 414, 424. The height of the outer peripheral end from the bottom surface part 411 is higher than the height of the outer peripheral end of the top surface part 424 in the intermediate part 42 from the bottom surface part 421. As a result, when a user stands up from a seated position, there is no resistance in front of the toilet seat, and the user can stand up smoothly, improving comfort.

The height of the outer peripheral end of the top surface part 424 in the intermediate part 42 from the bottom surface part 421 is the lowest in the height of the outer peripheral end of the top surface part 404 of the entire toilet seat 4 from the bottom surface part 401. This further improves comfort.

The pair of large curvature parts 41 have a pair of lateral parts 43 arranged on the opposite side to the middle part 42, and the large curvature part 41 has a seat surface whose width is wider than the width of the seat surface of the lateral parts 43. It is composed of large parts. This increases the area that supports the user's thighs and improves stability when sitting, providing a sense of security and improving sitting comfort.

The slope of the slope portion 425 in the intermediate portion 42 is greater than the slope of the slope portion 415 in the large curvature portion 41 . This improves the slidability of the toilet seat 4 with the toilet lid 12.

A preferred embodiment of the present disclosure has been described above. The present disclosure is not limited to the embodiments described above, and can be modified as appropriate.
