The upper plate 200 further has, for example, a bottom surface 230. The bottom surface 230 is the outer surface 21
0 and the lower end of the inner surface 220 are connected. The bottom surface 230 is, in other words, the lower end of the upper plate 200. The bottom surface 230 is, for example, a substantially horizontal plane.

The lower plate 100 has a side end face 110 facing the inner peripheral side. The side end surface 110 is, for example, the lower plate 1
00 is a portion where the opening 100a is formed. The side end face 110 extends in, for example, a substantially vertical direction. However, the side end surface 110 may be inclined with respect to the vertical direction. The side end face 110 is
It suffices to have at least a portion extending in the vertical direction (up-down direction) and facing the inner peripheral side.

The lower plate 100 further has, for example, a bottom surface 120. The lower end of the side end face 110 is, for example,
It is continuous with the bottom surface 120. In other words, the vertical position of the lower end of the side end surface 110 is
0 is substantially the same as the vertical position. In addition, a plurality of legs (cushion portions) that come into contact with the upper surface (rim surface) of the toilet 6 may be provided on a surface facing the lower side of the toilet seat 10 (a surface facing the toilet 6) (for example, FIG. 2). reference). The vertical position of the bottom surface 120 is a vertical position in a portion excluding such a leg portion.

The inner peripheral end 222 of the inner surface 220 of the upper plate 200 is located on the inner peripheral side with respect to the side end surface 110 of the lower plate 100 and is located below at least a part of the side end surface 110 of the lower plate 100. I do.

The inner surface 220 of the upper plate 200 has an opposing portion 224 facing the outer peripheral side and facing the side end surface 110 of the lower plate 100. The facing portion 224 is formed by arranging the end portion 222 as described above.
It is provided on the inner surface 220.

The inner peripheral side adhesive portion 300 is provided between the side end surface 110 of the lower plate 100 and the facing portion 224 of the inner surface 220 of the upper plate 200. As a result, the upper part of the adhesive part 300 is covered by the upper plate 200, the side part is covered by the side end face 110 and the facing part 224, and only the lower part is exposed. The bonding portion 300 bonds the inner peripheral sides of the lower plate 100 and the upper plate 200 with the side end surface 110 and the facing portion 224.

At least a part of the bonding portion 300 is located above a virtual line V1 orthogonal to the lower end 212a of the curved portion 212. The virtual line V1 is, in other words, the lower end 212a of the curved portion 212.

Further, at least a part of the bonding portion 300 is located on the inner peripheral side with respect to the virtual line V2 orthogonal to the upper end 212b of the curved portion 212. That is, at least a part of the bonding portion 300 is provided, for example, in a region surrounded by the curved portion 212, the virtual line V1, and the virtual line V2.

In this example, substantially the entirety of the bonding section 300 is located above the virtual line V1. Adhesive part 30
Substantially the entirety of 0 is provided in a region surrounded by the curved portion 212, the virtual line V1, and the virtual line V2. Substantially the entirety of the bonding portion 300 is, for example, a portion that is 90% or more of the bonding portion 300.

The vertical distance D1 between the lower end of the upper plate 200 and the lower end of the side end surface 110 of the lower plate 100 is:
It is shorter than the length L1 of the side end surface 110 in the vertical direction. The distance D1 is, in other words, the vertical distance between the bottom surface 230 of the upper plate 200 and the bottom surface 120 of the lower plate 100. The bottom surface 230 of the upper plate 200 is substantially flush with the bottom surface 120 of the lower plate 100, for example. The distance D1 is substantially 0, for example.

Thus, the vertical position of the lower end of the upper plate 200 is set to be substantially the same as the vertical position of the lower end of the side end surface 110 of the lower plate 100. The vertical position of the bottom surface 230 of the upper plate 200 is
It is set to be substantially the same as the vertical position of the bottom surface 120 of the lower plate 100 or higher than the bottom surface 120 of the lower plate 100.

Further, in this example, the vertical position of the lower end 212a of the curved portion 212 is
Is substantially the same as the position of the lower end in the vertical direction. In other words, in this example, the lower end of the outer surface 210 is the lower end 212a of the curved portion 212. The angle θ between the tangent to the lower end 212a of the curved portion 212 and the bottom surface 230 is, for example, less than 90 °.

However, the lower end of the outer surface 210 is not necessarily the lower end 212a of the curved portion 212.
The outer surface 210 may further have, for example, a portion extending vertically downward from the lower end 212a of the curved portion 212. The angle θ between the tangent to the lower end of the outer surface and the bottom surface 230 may be, for example, 90 ° or more.

The vertical length H1 (height) from the lower end of the outer surface 210 (the bottom surface 230 of the upper plate 200) to the upper end 212b of the curved portion 212 is, for example, 5 cm or less. The vertical length H1 from the lower end of the outer surface 210 to the upper end 212b of the curved portion 212 is, for example, the width W of the curved portion 212.
Shorter than one. The width W1 of the curved portion 212 is, for example, the horizontal width of the curved portion 212 in a cross section orthogonal to the direction along the opening 10a (the cross section shown in FIG. 4).

The bonding section 300 has a first portion 301 and a second portion 302. The first portion 301 is a portion provided between the side end surface 110 and the facing portion 224. The second portion 302 includes the first
A portion where the lower plate 100 and the upper plate 200 are bonded on the outer peripheral side of the portion 301. Second
The portion 302 extends, for example, from the upper end of the first portion 301 (the upper end of the side end surface 110) to the outer peripheral side, and bonds the upper surface 130 of the lower plate 100 and the inner surface 220 of the upper plate 200. The second portion 302 may be in contact with the first portion 301 as illustrated, or may be separated from the first portion 301 toward the outer periphery. The second portion 302 is provided as needed and can be omitted. The bonding section 300 may have at least the first portion 301.

The material of the second portion 302 is different from the material of the first portion 301. For the first portion 301, for example, an adhesive such as an epoxy resin is used. For the second portion 302, for example, a hot-melt adhesive such as synthetic rubber is used. For the lower plate 100 and the upper plate 200, for example, a thermosetting resin such as a urea resin or a melamine resin is used. Lower plate 100 and upper plate 20
For 0, for example, a thermoplastic resin such as polypropylene may be used. In addition, the bonding portion 30
The material of No. 0 is not limited to a material that is adhered by adhesion or adhesion, but may be a material that adheres the lower plate 100 and the upper plate 200 by welding, for example. In this case, for example, the same type of resin material as the lower plate 100 and the upper plate 200 may be used for the bonding portion 300.

As described above, according to the toilet seat 10 according to the present embodiment, the side end surface 11 of the lower plate 100
0 and the opposing portion 224 of the upper plate 200, the adhesive portion 3 on the inner peripheral side is provided.
00 can be turned downward. Therefore, it is possible to prevent the adhesive portion 300 from being exposed on the inner peripheral side of the toilet seat 10 and to prevent the adhesive portion 300 from contacting the user and impairing the sitting comfort. In addition, the design of the toilet seat 10 can be improved by directing the adhesive portion 300 downward and suppressing exposure to the inner peripheral side.

Then, by locating at least a part of the bonding portion 300 above the virtual line V1 orthogonal to the lower end 212a of the curved portion 212, the load when sitting on the toilet seat 10 is raised above the virtual line V1. It is possible to make it easy to act on at least a part of the bonded portion 300 in the direction of compression. As a result, the load at the time of sitting is reduced by the bonding portion 300 (side end surface 110).
Acting in the direction of increasing the distance between the contact portion 224 and the opposing portion 224), and a decrease in the adhesiveness of the adhesive portion 300 can be suppressed. For example, it is possible to suppress the occurrence of cracks, peeling, and the like in the bonding portion 300.

Therefore, in the toilet seat 10 according to the present embodiment, even when the inner peripheral adhesive portion 300 of the lower plate 100 and the upper plate 200 is directed downward, a decrease in the adhesiveness of the inner peripheral adhesive portion 300 is suppressed. A toilet seat that can be provided can be provided.

For example, the length H in the vertical direction from the lower end of the outer surface 210 to the upper end 212b of the curved portion 212
1 to 5 cm or less. Thereby, the design of the toilet seat 10 can be further improved. Furthermore, the load when sitting on the toilet seat 10 can be more easily applied to the adhesive portion 300 depending on the direction in which the adhesive portion 300 is compressed, and the adhesion of the adhesive portion 300 is more reliably prevented from being reduced. Can be.

The lower end 212a of the curved portion 212 is set to the lower end of the outer surface 210, and
The angle θ between the tangent to the lower end 212a of the second and the bottom surface 230 is set to less than 90 °. Accordingly, the load when the user sits on the toilet seat 10 can be more easily applied to the adhesive portion 300 in the direction of compressing the adhesive portion 300, and the adhesiveness of the adhesive portion 300 is more reliably prevented from being reduced. be able to.

In the toilet seat 10, the vertical distance D1 between the lower end of the upper plate 200 and the lower end of the side end face 110 is shorter than the vertical length L1 of the side end face 110. Accordingly, it is possible to suppress the lower end of the upper plate 200 from protruding excessively downward with respect to the lower end of the side end surface 110, and it is possible to further improve the design of the toilet seat 10. The load at the time of sitting on the toilet seat 10 can be easily applied to the adhesive portion 300 depending on the direction in which the adhesive portion 300 is compressed, and the decrease in the adhesiveness of the adhesive portion 300 can be more reliably suppressed. .

In the toilet seat 10, the bonding portion 300 has the first portion 301 and the second portion 302, and the material of the second portion 302 is different from the material of the first portion 301. Thereby, the first portion 301 and the second portion 302 can be used properly for different purposes, and the productivity of the toilet seat 10 can be further improved.

For example, when a thermosetting resin such as a urea resin or a melamine resin is used for the lower plate 100 and the upper plate 200, by using different materials for the first portion 301 and the second portion 302, respectively, The upper plate 200 can be more reliably and efficiently bonded.

For example, the second portion 302 of the adhesive is applied to the upper plate 200, and the lower plate 100 is bonded to the upper plate 200. Thus, the lower plate 100 and the upper plate 200 are temporarily fixed by the second portion 302, and the lower plate 100 and the upper plate 200 are positioned. Thereafter, the lower plate 100 and the upper plate 200 are permanently fixed by filling the first portion 301 as an adhesive between the side end surface 110 and the facing portion 224. Accordingly, even when a thermosetting resin such as a urea resin or a melamine resin is used for the lower plate 100 and the upper plate 200, the lower plate 100 and the upper plate 200 can be securely and efficiently bonded, and the toilet seat 10 can be improved in productivity.
