Description

  Aspects of the present invention generally relate to toilet seats.

  2. Description of the Related Art A hollow toilet seat is formed by combining and bonding an upper plate and a lower plate (for example, Patent Document 1). The bonding between the upper plate and the lower plate is performed by injecting an adhesive from the outside into a gap provided between the upper plate and the lower plate in a state where the upper plate and the lower plate are combined. At this time, if the adhesive leaks into the inner space side of the hollow toilet seat, the amount of the adhesive filled in the gap decreases, and the adhesiveness between the upper plate and the lower plate may be reduced. There is.

  For this reason, in the toilet seat formed by bonding the upper plate and the lower plate, even when the adhesive is injected from the outside and the upper plate and the lower plate are bonded, the leakage of the adhesive to the inner space side is suppressed. It is desirable to be able to do so.

  The present invention has been made based on the recognition of such a problem, and even when an adhesive is injected from the outside and the upper plate and the lower plate are bonded, leakage of the adhesive to the internal space side can be suppressed. The purpose is to provide a toilet seat.

  A first invention is a lower plate, an upper plate provided on the lower plate, forming an internal space between the lower plate, and an adhesive portion for bonding the lower plate and the upper plate, Wherein the lower plate has an upper surface facing upward and a side end surface facing sideways, the upper surface has a peripheral portion extending along the side end surface, and the upper plate has An inner surface facing the plate, an end of the inner surface of the upper plate is located on the side than the side end surface of the lower plate, and at least a part of the side end surface of the lower plate. And the inner surface of the upper plate is opposed to the side end surface to form a first space between the inner end surface and the side end surface, and is opposed to the peripheral edge portion of the upper surface. And a second space is formed between the first space and the second space, and the adhesive portion is provided in the first space. The lower plate and the upper plate are bonded by the side end surface and the inner surface, and the width between the lower plate and the upper plate in the third space is equal to the lower plate of the first space. And a width between the lower plate and the upper plate in the second space and a width between the lower plate and the upper plate in the second space.

  According to this toilet seat, since the third space is provided between the first space and the second space, when the adhesive is injected from the outside into the first space to provide the bonding portion, the bonding portion is formed by the second space. Leakage into the space and the internal space can be suppressed.

  According to a second aspect, in the first aspect, the bonding portion has a first portion provided in the first space and a second portion provided in the second space. It is a toilet seat.

  According to this toilet seat, by providing the second portion provided in the second space, the lower plate and the upper plate can be more appropriately bonded. Further, by providing the third space, even when the second portion is provided in the second space, it is possible to suppress the second portion from leaking to the first space side. That is, when the adhesive is injected into the first space from the outside, it is possible to suppress the second portion from affecting the injection of the adhesive.

  A third invention is characterized in that, in the first or second invention, a portion of the inner surface forming the third space is substantially parallel to a portion of the lower plate forming the third space. Toilet seat.

  According to this toilet seat, the portion that forms the third space of the inner surface and the portion that forms the third space of the lower plate are made substantially parallel, so that the lower plate and the upper plate are formed along a substantially parallel surface. Even when the position is shifted, the width of the third space can be prevented from changing. Thus, even when the lower plate and the upper plate are misaligned, it is possible to appropriately prevent the bonding portion from leaking into the second space and the internal space.

  In a fourth aspect based on the third aspect, the peripheral portion has a planar shape, and the inner surface faces the peripheral portion to form the second space, and faces the peripheral portion. A toilet seat that forms the third space.

  According to this toilet seat, the width of the third space can be reduced even when the lower plate and the upper plate are misaligned in the horizontal direction when the lower plate and the upper plate are combined when the planar peripheral portion is made substantially horizontal. Can be suppressed from changing. Thereby, even when the displacement between the lower plate and the upper plate occurs in the horizontal direction, it is possible to appropriately suppress the leakage of the bonding portion into the second space and the internal space. This makes it possible to more easily absorb the positional deviation between the lower plate and the upper plate, thereby making it easier to manufacture the toilet seat.

  According to the aspect of the present invention, there is provided a toilet seat capable of suppressing leakage of the adhesive to the internal space side even when the upper plate and the lower plate are bonded by injecting an adhesive from the outside.

Hereinafter, embodiments will be described with reference to the drawings. In each of the drawings, similar components are denoted by the same reference numerals, and detailed description will be omitted as appropriate.
FIG. 1 is a perspective view schematically illustrating a toilet apparatus provided with a toilet seat according to the embodiment.
As shown in FIG. 1, the toilet device 2 includes a toilet seat device 4 and a Western-style sitting toilet (hereinafter simply referred to as a “toilet”) 6.

  The toilet seat device 4 is mounted on the toilet 6. The toilet seat device 4 may be integrally attached to the toilet 6 or may be detachably attached to the toilet 6. The toilet seat device 4 includes a toilet seat 10, a toilet lid 12, and a main body 14.

  Here, in the specification of the present application, the upper side is defined as “upper” when viewed from the user sitting on the toilet seat 10, and the lower side is defined as “downward” when viewed from the user sitting on the toilet seat 10. Further, when viewed from the user sitting on the toilet seat 10 with the back facing the toilet lid 12 in the open state, the left-right direction is “left” and “right”, respectively, and the front-rear direction is “front” and “rear”, respectively. ". FIG. 1 illustrates an example of an upper UW, a lower DW, a left LW, a right RW, a front FW, and a rear BW.

  The toilet 6 has a bowl portion 6a that is recessed downward. The toilet bowl 6 receives user's excrement such as urine and stool in the bowl portion 6a. The main body 14 of the toilet seat device 4 is provided at an upper part of the toilet 6 behind the bowl 6 a. The main body 14 pivotally supports the toilet seat 10 and the toilet lid 12 so that they can be opened and closed.

  The toilet seat 10 has an opening 10a. The toilet seat 10 is provided on the toilet bowl 6 so as to surround the outer edge of the bowl portion 6a, and the bowl portion 6a is exposed through the opening 10a. Thus, the user can excrete the bowl portion 6a while sitting on the toilet seat 10. In this example, a so-called O-shaped toilet seat 10 in which a through-hole-shaped opening 10a is formed is shown. The toilet seat 10 is not limited to the O-shape, but may be a U-shape. Inside the toilet seat 10, a heater or the like for appropriately heating the seating portion (the portion where the user's buttocks come into contact) is provided as appropriate.

FIG. 2 is an exploded perspective view schematically illustrating the toilet seat according to the embodiment.
As shown in FIG. 2, the toilet seat 10 includes a lower plate 100 and an upper plate 200. The upper plate 200 is provided on the lower plate 100. Note that, here, the directions such as “up” and “down” correspond to a state in which the lower plate 100 of the toilet seat 10 is placed on a horizontal plane (a state in which the lower plate 100 is placed on the toilet bowl 6 and a user can sit down). Is based on

  As shown in FIG. 2, the lower plate 100 and the upper plate 200 have an opening 100a and an opening 200a, respectively. The shapes of the lower plate 100 and the upper plate 200 viewed from above are substantially the same as the shapes of the toilet seat 10 viewed from above. That is, the shape of the lower plate 100 and the upper plate 200 as viewed from above is annular or U-shaped. The opening 10a of the toilet seat 10 is formed by the opening 100a of the lower plate 100 and the opening 200a of the upper plate 200.

FIG. 3 is a cross-sectional view schematically illustrating a part of the toilet seat according to the embodiment.
FIG. 3 schematically illustrates a cross section taken along line A1-A2 of FIG.
As shown in FIG. 3, the toilet seat 10 further includes bonding portions 300 and 320 for bonding the lower plate 100 and the upper plate 200.

  The bonding part 300 bonds the inner peripheral sides of the lower plate 100 and the upper plate 200. The bonding section 320 bonds the outer peripheral sides of the lower plate 100 and the upper plate 200. Here, the “inner peripheral side” is a side facing the openings 10a, 100a, 200a, and the “outer peripheral side” is a side opposite to the side facing the openings 10a, 100a, 200a.

  For example, the bonding portion 300 bonds the inner peripheral sides of the lower plate 100 and the upper plate 200 in a ring shape over substantially the entire circumference. The bonding section 320 bonds the outer peripheral sides of the lower plate 100 and the upper plate 200 in a ring shape over substantially the entire circumference, for example. Accordingly, it is possible to suppress the occurrence of a gap between the lower plate 100 and the upper plate 200, and to appropriately bond the lower plate 100 and the upper plate 200.

  Note that the structure of the hinge portion of the toilet seat 10 that is pivotally supported by the toilet seat device 4 may be different from the structure of the main body portion of the toilet seat 10 on which the user sits. For example, the adhesive part 320 on the outer peripheral side may not be provided on the hinge part.

  The lower plate 100 is, for example, a flat plate. The upper plate 200 has, for example, a plate shape curved upward. In other words, the upper plate 200 has a substantially U-shaped cross section that opens downward. Thus, the upper plate 200 forms an internal space SP between the upper plate 200 and the lower plate 100. The lower plate 100 and the upper plate 200 are bonded to each other by the bonding portions 300 and 320 to form the hollow toilet seat 10 having the internal space SP.

  The upper plate 200 is formed one size larger than the lower plate 100. The inner peripheral end of the upper plate 200 is located closer to the inner peripheral side than the inner peripheral end of the lower plate 100. The outer peripheral end of the upper plate 200 is located on the outer peripheral side of the outer peripheral end of the lower plate 100.

  The bonding portion 300 is provided between the inner peripheral end of the lower plate 100 and the inner peripheral end of the upper plate 200. For example, the bonding portion 300 is exposed only below, and is not exposed above and on the inner peripheral side. Thereby, the design of the toilet seat 10 can be enhanced. In addition, it is possible to prevent the adhesive part 300 (the joint between the lower plate 100 and the upper plate 200) from coming into contact with the buttocks or the legs of the user sitting on the toilet seat 10, and to enhance the sitting comfort of the toilet seat 10. Can also.

  The bonding portion 320 is provided between the outer peripheral end of the lower plate 100 and the outer peripheral end of the upper plate 200. The bonding portion 320 is, for example, exposed only below, and not exposed above and on the outer peripheral side. Thereby, the design of the toilet seat 10 can be further enhanced.

FIG. 4 is an enlarged cross-sectional view schematically illustrating a part of the toilet seat according to the embodiment.
FIG. 4 schematically shows an enlarged portion of the encircling line B in FIG. That is, FIG. 4 schematically shows an enlarged inner peripheral portion of the cross section of the toilet seat 10.

  As shown in FIG. 4, the upper plate 200 has an outer surface 210 and an inner surface 220. The outer surface 210 has a curved portion 212 that is curved in an upwardly convex shape so as to descend downward toward the inner peripheral side. The inner surface 220 faces the lower plate 100.

  The upper plate 200 further has, for example, a bottom surface 230. The bottom surface 230 connects the lower end of the outer surface 210 and the lower end of the inner surface 220. 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 surface 110, a bottom surface 120, and an upper surface 130. The upper surface 130 faces upward. The upper surface 130 faces the inner surface 220 of the upper plate 200. The side end face 110 faces sideways. In other words, the side end surface 110 is a surface facing the inner peripheral side. The side end surface 110 is, for example, a portion where the opening 100a of the lower plate 100 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 may have at least a portion extending in the vertical direction (up and down direction) and facing the inner peripheral side.

  The lower end of the side end surface 110 is continuous with the bottom surface 120, for example. In other words, the vertical position of the lower end of the side end surface 110 is substantially the same as the vertical position of the bottom surface 120. 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 bottom surface 230 of the upper plate 200 is substantially flush with the bottom surface 120 of the lower plate 100, 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 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.

  In this example, the vertical position of the lower end 212a of the curved portion 212 is substantially the same as the vertical position of the lower end of the upper plate 200. In other words, in this example, the lower end of the outer surface 210 is the lower end 212a of the curved portion 212.

  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 inner peripheral end 222 of the inner surface 220 of the upper plate 200 is located on the inner peripheral side (the side facing the side end surface 110) than the side end surface 110 of the lower plate 100, and the side end surface of the lower plate 100. It is located below at least a part of 110.

  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 provided on the inner surface 220 by arranging the end portion 222 as described above.

  The upper surface 130 of the lower plate 100 has a peripheral portion 132 extending along the side end surface 110. In other words, the peripheral portion 132 extends along the inner peripheral edge of the lower plate 100. The peripheral portion 132 has, for example, a planar shape. In other words, the peripheral portion 132 is a surface substantially parallel to one plane. The peripheral portion 132 has, for example, a horizontal plane shape. Therefore, when the lower plate 100 is placed so that the peripheral portion 132 is horizontal, the height of the peripheral portion 132 is substantially constant. A part of the peripheral part 132 is substantially flush with another part of the peripheral part 132 on the opposite side across the opening 100a. Here, “substantially parallel” means, for example, a state in which the difference in distance between two surfaces facing each other is 2 mm or less over the entire two surfaces. In addition, “substantially flush” refers to, for example, a state where the difference between the heights of the two surfaces is 2 mm or less.

  The peripheral portion 132 extends annularly along the side end surface 110 (inner peripheral edge) of the lower plate 100, for example. The peripheral portion 132 is provided, for example, over the entire periphery of the inner peripheral edge of the lower plate 100. However, the peripheral portion 132 does not necessarily need to be provided on the entire periphery, and may have a discontinuous portion in a part in the circumferential direction along the inner peripheral edge. The upper surface 130 may have, for example, a plurality of peripheral portions 132 arranged along the inner peripheral edge. In this case, the plurality of peripheral portions 132 are arranged on the same plane. In other words, the plurality of peripheral portions 132 are substantially flush. In the plurality of peripheral portions 132, a configuration may be employed in which a part of the plurality of peripheral portions 132 is substantially flush and another portion different from the one is substantially flush. In other words, the plurality of peripheral portions 132 may have a first group and a second group. The plurality of peripheral portions 132 included in the first group are substantially flush with each other. The plurality of peripheral portions 132 included in the second group are set at different heights from the plurality of peripheral portions 132 of the first group, and are substantially flush with each other. Further, the plurality of peripheral portions 132 may have two or more groups having different heights.

  The inner surface 220 of the upper plate 200 has a facing portion 226 facing the peripheral portion 132. The facing portion 226 extends, for example, along the inner peripheral edge of the upper plate 200 and has a planar shape substantially parallel to the peripheral portion 132. The facing portion 226 has, for example, a horizontal plane shape. The facing portion 226 extends annularly, for example, along the inner peripheral edge of the upper plate 200. The facing portion 226 is provided, for example, over the entire inner peripheral edge of the upper plate 200. However, like the peripheral portion 132, the facing portion 226 may have a portion interrupted in a part of the circumferential direction along the inner peripheral edge. The inner surface 220 may have, for example, a plurality of opposing portions 226 arranged along the inner peripheral edge similarly to the upper surface 130.

  Further, the inner surface 220 of the upper plate 200 further has an opposing portion 228 opposing the peripheral portion 132. The facing part 228 is provided between the facing part 224 and the facing part 226. In other words, the facing portion 228 is provided on the inner peripheral side of the facing portion 226. The opposing portion 228 protrudes below the opposing portion 226 and reduces the distance between the opposing portion 226 and the peripheral portion 132. The facing portion 228 extends, for example, along the inner peripheral edge of the upper plate 200 and has a planar shape substantially parallel to the peripheral portion 132. Hereinafter, the opposing portion 228 is the same as the opposing portion 226, and a detailed description thereof will be omitted.

  Thus, the inner surface 220 of the upper plate 200 faces the side end surface 110 to form the first space S1 between the inner surface 220 and the side end surface 110, and faces the periphery 132 of the upper surface 130 and faces the periphery 132. A second space S2 is formed at the same time, and a third space S3 is formed between the first space S1 and the second space S2. The inner surface 220 faces the peripheral portion 132 to form a third space S3.

  The first space S1 is, in other words, a space between the side end surface 110 and the facing portion 224. The second space S2 is, in other words, a space between the peripheral portion 132 and the facing portion 226. The third space S3 is, in other words, a space between the peripheral portion 132 and the facing portion 228.

  As described above, the facing portion 228 is substantially parallel to the peripheral portion 132. Therefore, the portion of the inner surface 220 that forms the third space S3 (the facing portion 228) is substantially parallel to the portion of the lower plate 100 that forms the third space S3 (the peripheral portion 132).

  The width W3 between the lower plate 100 and the upper plate 200 of the third space S3 is the same as the width W1 between the lower plate 100 and the upper plate 200 of the first space S1, and the width W1 of the second space S2. It is smaller than the width W2 between the plate 200.

  The width W1 is, in other words, the distance between the side end surface 110 and the facing portion 224. The width W2 is, in other words, the distance between the peripheral portion 132 and the facing portion 226. The width W3 is, in other words, the distance between the peripheral portion 132 and the facing portion 228.

  The inner peripheral adhesive portion 300 is provided in the first space S1 (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.

  Further, the bonding portion 300 is also provided in the second space S2 (between the peripheral portion 132 and the facing portion 226). The bonding portion 300 bonds the lower plate 100 and the upper plate 200 also at the peripheral portion 132 and the facing portion 226.

  The bonding section 300 has, for example, a first portion 301 and a second portion 302. The first portion 301 is a portion provided in the first space S1. The second portion 302 is a portion provided in the second space S2.

  In this example, a part of the first part 301 enters the third space S3, and a part of the second part 302 enters the third space S3, and the first part 301 and the second part 302 in the third space S3. Is in contact. Without being limited to this, the second portion 302 may be separated from the first portion 301. The first portion 301 and the second portion 302 do not have to enter the third space S3.

  The material of the second portion 302 is different from the material of the first portion 301, for example. 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. However, the material of the second portion 302 may be the same as the material of the first portion 301.

  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. For the lower plate 100 and the upper plate 200, for example, a thermoplastic resin such as polypropylene may be used. Further, the material of the bonding portion 300 is not limited to a material that is bonded by adhesion or adhesion, and may be a material that bonds 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.

FIG. 5 is an enlarged cross-sectional view schematically illustrating a part of the toilet seat according to the embodiment.
FIG. 5 schematically shows an enlarged portion of the encircling line C in FIG. That is, FIG. 5 schematically shows an enlarged outer peripheral portion of the cross section of the toilet seat 10.

  As shown in FIG. 5, the upper plate 200 further has, for example, a bottom surface 232 that connects a lower end on the outer peripheral side of the outer surface 210 and a lower end on the outer peripheral side of the inner surface 220. The bottom surface 232 is, in other words, a lower end on the outer peripheral side of the upper plate 200. The bottom surface 232 is, for example, a substantially horizontal plane.

  The lower plate 100 further has a side end surface 112. The side end surface 112 faces sideways. In other words, the side end surface 112 is a surface facing the outer peripheral side. The side end surface 112 extends in, for example, a substantially vertical direction. However, the side end surface 112 may be inclined with respect to the vertical direction. The side end surface 112 may extend at least in the vertical direction (vertical direction) and have a portion facing the outer peripheral side.

  The lower end of the side end surface 112 is continuous with the bottom surface 120, for example. In other words, the vertical position of the lower end of the side end surface 112 is substantially the same as the vertical position of the bottom surface 120.

  The bottom surface 232 of the upper plate 200 is substantially flush with the bottom surface 120 of the lower plate 100, for example. Thus, the vertical position of the lower end of the upper plate 200 on the outer peripheral side is set to be substantially the same as the vertical position of the lower end of the side end surface 112 of the lower plate 100. The vertical position of the bottom surface 232 of the upper plate 200 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 lower surface 120 of the lower plate 100.

  The end 240 on the outer peripheral side of the inner surface 220 of the upper plate 200 is located on the outer peripheral side (the side facing the side end surface 112) than the side end surface 112 of the lower plate 100, and at least the side end surface 112 of the lower plate 100. It is located below some.

  The inner surface 220 of the upper plate 200 has an opposing portion 242 that faces the inner peripheral side and faces the side end surface 112 of the lower plate 100. The facing portion 242 is provided on the inner surface 220 by arranging the end portion 240 as described above.

  The upper surface 130 of the lower plate 100 has a peripheral portion 134 extending along the side end surface 112. In other words, the peripheral portion 134 extends along the outer peripheral edge of the lower plate 100. The peripheral portion 134 is, for example, planar. In other words, the peripheral portion 134 is a surface substantially parallel to one plane. The peripheral portion 134 has, for example, a horizontal plane shape. Therefore, when the lower plate 100 is placed so that the peripheral portion 134 is horizontal, the height of the peripheral portion 134 is substantially constant. A part of the peripheral part 134 is substantially flush with another part of the peripheral part 134 on the opposite side across the opening 100a.

  The peripheral portion 134 extends annularly along the side end surface 112 (outer peripheral edge) of the lower plate 100, for example. The peripheral portion 134 is provided, for example, over the entire outer peripheral edge of the lower plate 100. However, the peripheral portion 134 does not necessarily need to be provided on the entire periphery, and may have a portion interrupted in a part of the circumferential direction along the outer peripheral edge. The upper surface 130 may have, for example, a plurality of peripheral portions 134 arranged along the outer peripheral edge. In this case, the plurality of peripheral portions 134 are arranged on the same plane. In other words, the plurality of peripheral portions 134 are substantially flush. In addition, similarly to the inner peripheral side 132, in the plurality of peripheral parts 134, a part of the plurality of peripheral parts 134 is substantially flush, and another part different from the part is substantially flush. The configuration may be as follows.

  The inner surface 220 of the upper plate 200 has a facing portion 244 facing the peripheral portion 134. The facing portion 244 extends, for example, along the outer peripheral edge of the upper plate 200 and has a planar shape substantially parallel to the peripheral portion 134. The facing part 244 is, for example, in a horizontal plane. The facing portion 244 extends annularly along the outer peripheral edge of the upper plate 200, for example. The facing portion 244 is provided, for example, over the entire outer peripheral edge of the upper plate 200. However, like the peripheral portion 134, the facing portion 244 may have a portion interrupted in a part of the circumferential direction along the outer peripheral edge. The inner surface 220 may have, for example, a plurality of opposing portions 244 arranged along the outer peripheral edge similarly to the upper surface 130.

  Further, the inner surface 220 of the upper plate 200 further has an opposing portion 246 opposing the peripheral portion 134. The facing part 246 is provided between the facing part 242 and the facing part 244. In other words, the facing portion 246 is provided on the outer peripheral side of the facing portion 244. The opposing portion 246 projects below the opposing portion 244 and reduces the distance between the opposing portion 244 and the peripheral portion 134. The facing portion 246 extends, for example, along the outer peripheral edge of the upper plate 200 and has a planar shape substantially parallel to the peripheral portion 134. Hereinafter, the facing portion 246 is the same as the facing portion 244, and thus a detailed description is omitted.

  As a result, the inner surface 220 of the upper plate 200 faces the side end surface 112 to form a fourth space S4 (first outer circumferential side space) between the inner surface 220 and the side end surface 112, and faces the peripheral portion 134 of the upper surface 130. To form a fifth space S5 (an outer peripheral side second space) between the peripheral space 134 and the sixth space S6 (an outer peripheral side third space) between the fourth space S4 and the fifth space S5. ) Is formed. The inner surface 220 faces the peripheral portion 134 to form a sixth space S6.

  The fourth space S4 is, in other words, a space between the side end surface 112 and the facing portion 242. The fifth space S5 is, in other words, a space between the peripheral portion 134 and the facing portion 244. The sixth space S6 is, in other words, a space between the peripheral portion 134 and the facing portion 246.

  As described above, the facing portion 246 is substantially parallel to the peripheral portion 134. Therefore, the portion of the inner surface 220 that forms the sixth space S6 (the facing portion 246) is substantially parallel to the portion of the lower plate 100 that forms the sixth space S6 (the peripheral portion 134).

  The width W6 between the lower plate 100 and the upper plate 200 of the sixth space S6 is equal to the width W4 between the lower plate 100 and the upper plate 200 of the fourth space S4 and the width W4 of the fifth space S5. It is smaller than the width W5 between the plate 200.

  The width W4 is, in other words, the distance between the side end surface 112 and the facing portion 242. The width W5 is, in other words, the distance between the peripheral portion 134 and the facing portion 244. The width W6 is, in other words, the distance between the peripheral portion 134 and the facing portion 246.

  The outer peripheral side bonding portion 320 is provided in the fourth space S4. As a result, the upper part of the adhesive part 320 is covered by the upper plate 200, the side part is covered by the side end surface 112 and the facing part 242, and only the lower part is exposed. The bonding portion 320 bonds the outer peripheral sides of the lower plate 100 and the upper plate 200 with the side end surface 112 and the facing portion 242.

  Further, the bonding section 320 is also provided in the fifth space S5. The bonding portion 320 bonds the lower plate 100 and the upper plate 200 also at the peripheral portion 134 and the facing portion 244.

  The bonding section 320 has, for example, a third portion 323 and a fourth portion 324. The third portion 323 is a portion provided in the fourth space S4. The fourth portion 324 is a portion provided in the fifth space S5.

  In this example, a part of the third part 323 enters the sixth space S6, and a part of the fourth part 324 enters the sixth space S6, and the third part 323 and the fourth part 324 in the sixth space S6. Is in contact. Without being limited to this, the fourth portion 324 may be separated from the third portion 323. The third portion 323 and the fourth portion 324 do not have to enter the sixth space S6.

  The material of the fourth portion 324 is different from the material of the third portion 323, for example. The third portion 323 is made of, for example, substantially the same material as the first portion 301 of the inner peripheral side adhesive portion 300. The fourth portion 324 is made of, for example, substantially the same material as the second portion 302 of the inner-side adhesive portion 300.

  In the manufacture of the toilet seat 10, for example, the second portion 302 of the adhesive is applied to the facing portion 226 of the upper plate 200, the fourth portion 324 of the adhesive is applied to the facing portion 244, and the lower plate is attached to the upper plate 200. Adhere 100. Thus, the lower plate 100 and the upper plate 200 are temporarily fixed by the second portion 302 and the fourth portion 324, and the lower plate 100 and the upper plate 200 are positioned.

  Thereafter, the first portion 301 as an adhesive is filled between the side end surface 110 and the facing portion 224, and the third portion 323 as the adhesive is filled between the side end surface 112 and the facing portion 242. Thereby, the lower plate 100 and the upper plate 200 are permanently fixed.

  Thus, for example, 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. Thus, the productivity of the toilet seat 10 can be improved.

  As described above, in the toilet seat 10 according to the present embodiment, by providing the third space S3 between the first space S1 and the second space S2, the adhesive is injected into the first space S1 from the outside. Thus, when the inner peripheral side bonding portion 300 is provided, it is possible to suppress the bonding portion 300 from leaking into the second space S2 and the internal space SP. Similarly, by providing the sixth space S6 between the fourth space S4 and the fifth space S5, when the adhesive is injected into the fourth space S4 from the outside to provide the outer peripheral bonding portion 320, Leakage of the bonding portion 320 into the fifth space S5 and the internal space SP can be suppressed.

  In the above-described embodiment, the third space S3 is provided on the inner peripheral side of the toilet seat 10, and the sixth space S6 is provided on the outer peripheral side of the toilet seat 10. The space for reducing the width (third space) does not necessarily need to be provided on both the inner peripheral side and the outer peripheral side, and may be provided on at least one side. Hereinafter, the sixth space S6 is the same as the third space S3.

  In the toilet seat 10, by providing the second portion 302 provided in the second space S2, the lower plate 100 and the upper plate 200 can be more appropriately bonded. Further, by providing the third space S3, even when the second portion 302 is provided in the second space S2, it is possible to suppress the second portion 302 from leaking to the first space S1 side. . That is, it is possible to prevent the second portion 302 from affecting the injection of the adhesive when the adhesive is injected into the first space S1 from the outside.

  Further, in the toilet seat 10, the portion (the facing portion 228) of the inner surface 220 forming the third space S3 and the portion (the peripheral portion 132) of the lower plate 100 forming the third space S3 are substantially parallel to each other. Thereby, even when the positions of the lower plate 100 and the upper plate 200 are displaced along the substantially parallel plane, it is possible to prevent the width W3 of the third space S3 from changing. Accordingly, even when the lower plate 100 and the upper plate 200 are misaligned, it is possible to appropriately suppress the bonding portion 300 from leaking into the second space S2 and the internal space SP.

  Further, in the toilet seat 10, the peripheral portion 132 has a planar shape, and the inner surface 220 faces the peripheral portion 132 to form a second space S <b> 2, and also faces the peripheral portion 132 to form a third space S <b> 3. I do. Accordingly, even when the lower plate 100 and the upper plate 200 are displaced in the horizontal direction when the lower plate 100 and the upper plate 200 are combined with the planar peripheral portion 132 being substantially horizontal, the third space is formed. A change in the width W3 of S3 can be suppressed. Thereby, even when the displacement between the lower plate 100 and the upper plate 200 occurs in the horizontal direction, etc., it is possible to appropriately prevent the adhesive portion 300 from leaking into the second space S2 and the internal space SP. . This makes it easier to absorb the positional deviation between the lower plate 100 and the upper plate 200, and to make the toilet seat 10 easier to manufacture.

  In the above embodiment, the inner surface 220 faces the peripheral portion 132 to form the third space S3. Without being limited to this, the inner surface 220 may, for example, face the side end surface 110 to form the third space S3. However, the configuration of the third space S3 is not limited to the above, and any configuration that is provided between the first space S1 and the second space S2 and has a smaller width than the first space S1 and the second space S2. Is fine.
