[0008] [1] The toilet seat of the present disclosure has a seating surface softer than the legs provided on the toilet lid, and a recess is provided in a portion of the seating surface corresponding to the legs. According to such a configuration, since the recess is provided in the soft seating surface from the beginning and the legs of the toilet lid do not cause a dent in the seating surface, it is difficult for the user to feel that this is a defective product. Therefore, the toilet lid can be made a common component for both a toilet seat with a hard seating surface and a toilet seat with a soft seating surface. [2] In the toilet seat described in [1] above, it may have a toilet seat main body portion made of foamed resin, and in a fallen state along the upper surface of the toilet body, the recess and the legs may not be in contact with each other. According to such a configuration, since the legs of the toilet lid do not hit the seating surface, it is possible to surely prevent a dent from being generated by the legs hitting the seating surface. [3] In the toilet seat described in [2] above, it may be rotatable between the fallen state and a standing state rising on the upper surface of the toilet body, and the recess may not be in contact with the legs even during rotation. According to such a configuration, since the legs of the toilet lid do not hit the seating surface even when the toilet seat is rotated, it is possible to surely prevent a dent from being generated by the legs hitting the seating surface. [4] In the toilet seat according to [1] above, it may have a toilet seat main body portion and a toilet seat cover made of foamed resin that is installed on the upper surface of the toilet seat main body portion and serves as a seating surface, and the concave portion may be provided on the toilet seat cover. According to such a configuration, since the concave portion is provided on the toilet seat cover from the beginning, and the recess does not occur on the seating surface when the leg portion of the toilet lid hits it, it is difficult for the user to feel that this is a defective product. Therefore, the toilet lid can be a common component for a toilet seat with a hard seating surface and a toilet seat with a soft toilet seat cover installed on the upper surface. [5] In the toilet seat according to any one of [1] to [4] above, the concave portion may be provided at the center in the left - right direction of the seating surface. According to such a configuration, It is possible to prevent a recess from occurring on the seating surface due to the leg portions provided at the center in the left - right direction of the toilet lid. [6] The toilet seat device of the present disclosure includes the toilet seat according to any one of [1] to [5] above, a toilet lid having leg portions, and a support portion that supports the toilet seat and the toilet lid.

[0009] <Embodiment 1> As shown in FIG. 1, the toilet seat 10 in the present embodiment is provided in the toilet seat device 40. The toilet seat device 40 is provided in the wash - type toilet 43. The wash - type toilet 43 includes a toilet body 44 and a toilet seat device 40. The toilet body 44 is made of pottery and has a toilet bowl portion 45. The toilet seat device 40 includes a toilet seat 10, a toilet lid 30, and a support portion 41. The toilet seat 10 has a seating surface 17 that is softer than a normal toilet seat, and the sitting comfort of the toilet seat 10 is comfortable.

[0010] Hereinafter, in each component member, the X - axis direction is described as the front, the Z - axis direction is described as the upper, and the Y - axis direction is described as the left. The side of the toilet body 44 where the toilet bowl portion 45 is provided is the front side, and the side where the toilet seat device 40 is attached is the rear side. The Z - axis extends in the vertical direction.

[0011] As shown in FIG. 2, the support portion 41 rotatably supports the toilet seat 10 and the toilet lid 30 in the fallen state and the upright state, respectively. The support portion 41 includes a casing 42, a toilet lid shaft portion 46, a toilet seat shaft portion 47, and various functional components (not shown). The fallen state is a state in which the toilet seat 10 is tilted along the upper surface of the toilet body 44. The upright state is a state in which the toilet seat 10 stands upward from the upper surface of the toilet body 44.

[0012] As shown in FIG. 1, the toilet lid 30 has a lid main body portion 31, a lid peripheral portion 32, and a lid hinge portion 33. The toilet lid 30 is formed of a hard resin material. The lid main body portion 31 covers the upper surface of the toilet seat 10 and the entire opening of the toilet bowl portion 45 in the fallen state.

[0013] The lid main body portion 31 has legs 34. The legs 34 have rubber feet, and when the rubber feet contact a normal hard toilet seat, they are in a state of contacting the seating surface. Thereby, the toilet lid 30 is supported by a normal hard toilet seat. The legs 34 are provided so as to protrude from the lid main body portion 31. The legs 34 are arranged at the center in the left-right direction of the lid main body portion 31. The contact surface of the legs 34 with the toilet seat 10 is formed of a resin material having elasticity such as synthetic rubber. The legs 34 are provided at the upper part of the lid main body portion 31 in the upright state. When the upright toilet lid 30 is viewed from the front side, the legs 34 have a vertically long shape.

[0014] The lid peripheral portion 32 is provided at the outer peripheral edge of the lid main body portion 31. The lid peripheral portion 32 covers the outer surface 21 of the toilet seat 10 in the fallen state. The lid hinge portion 33 is assembled to the toilet lid shaft portion 46 of the support portion 41.

[0015] The toilet seat 10 has a toilet seat main body portion 11 and a toilet seat hinge portion 12. The toilet seat main body portion 11 is made of foamed resin obtained by foam-molding a soft resin such as polyethylene. The toilet seat main body portion 11 may be manufactured by a molding method such as heat compression molding, cold press molding, or vacuum molding. The toilet seat hinge portion 12 is attached to the rear end portion of the toilet seat main body portion 11. The toilet seat hinge portion 12 is made of hard resin. The toilet seat hinge portion 12 is, for example, polypropylene resin or the like. The toilet seat hinge portion 12 is assembled to the toilet seat shaft portion 47 of the support portion 41.

[0016] The toilet seat main body portion 11 includes a front portion 13, a rear portion 14, and left and right side portions 15, and has an annular shape with an opening 16 formed at the center. The shape of the opening 16 is an oval shape that tapers toward the front portion 13 side in plan view.

[0017] The toilet seat main body portion 11 includes a seating surface 17, a lower surface 18, an inner surface 19, and an outer surface 21. As shown in FIG. 3, the seating surface 17 slopes downward from the outer peripheral side toward the inner peripheral side. In the fallen state, the lid main body portion 31 contacts the seating surfaces 17 of the left and right side portions 15. Thereby, the toilet lid 30 is supported by the toilet seat 10. Since the seating surface 17 is soft, even if the hard lid main body portion 31 contacts it, it is possible to prevent the lid main body portion 31 from being damaged or the generation of collision noise. Since the contact area between the lid main body portion 31 and the toilet seat main body portion 11 is large, the support load acting on the seating surface 17 of the toilet seat main body portion 11 is dispersed. Thereby, it is possible to prevent the support load of the toilet lid 30 from acting concentratedly on a part of the toilet seat main body portion 11, and to prevent deformation of the toilet seat main body portion 11.

[0018] As shown in FIG. 1, the lower surface 18 faces the upper surface of the toilet bowl main body 44 in the fallen state. Since the elasticity of the toilet seat main body portion 11 is high, the lower surface 18 may be flat without providing rubber legs or the like. The inner surface 19 constitutes the peripheral surface of the opening 16. The inner surface 19 slopes toward the center side of the opening 16 from the upper end to the lower end (see FIG. 3). The outer surface 21 faces the side opposite to the opening 16.

[0019] As shown in Fig. 1, a recess 22 is provided in a portion of the seating surface 17 corresponding to the legs 34. The recess 22 is located at the center in the left - right direction of the front part 13. The recess 22 is formed on the rear side of the front part 13. In the front part 13, a tip part 23 is left in front of the recess 22. The tip part 23 is continuously connected without a step from the left and right side parts 15 and closes the front of the recess 22.

[0020] As shown in Fig. 4, in a plan view, the left - right dimension of the recess 22 increases from the front side to the rear side. As shown in Fig. 5, when viewed from the rear, the left - right dimension of the recess 22 decreases from the upper side to the lower side.

[0021] As shown in Fig. 6, the up - down dimension of the recess 22 increases from the front side to the rear side. The upper end of the recess 22 is located on the seating surface 17. The lower end of the recess 22 is located on the inner surface 19.

[0022] The recess 22 has a front - side region 24 and a rear - side region 25. The front - side region 24 is located above the rear - side region 25. The bending direction of the front - side region 24 is different from that of the rear - side region 25. The front - side region 24 bulges upward and curves. The center point of the bending of the front - side region 24 is located inside the front part 13. The rear - side region 25 is recessed downward and curves. The center point of the bending of the rear - side region 25 is located outside the front part 13.

[0023] In the collapsed state, as shown in Fig. 6, the legs 34 are located above the rear - side region 25. In the collapsed state, the recess 22 and the legs 34 are not in contact.

[0024] During the rotation of the toilet seat 10 and the toilet lid 30, as shown in Fig. 7, the legs 34 do not contact the recess 22 and only contact the tip part 23. The contact force between the legs 34 and the tip part 23 is strong enough not to deform the tip part 23. Even if the legs 34 and the tip part 23 come into contact during the rotation of the toilet seat 10 and the toilet lid 30, the legs 34 do not continuously hit the same position of the tip part 23, so the tip part 23 is not deformed.

[0025] In the standing state, as shown in FIG. 8, the leg portion 34 is disposed at a height position equivalent to that of the tip portion 23. In the standing state, the leg portion 34 does not contact the recess 22 and only contacts the tip portion 23. The contact force between the leg portion 34 and the tip portion 23 is of a strength that does not deform the tip portion 23.

[0026] According to the embodiment configured as described above, the following effects are achieved. The toilet seat 10 has a seating surface 17 that is softer than the leg portion 34 provided on the toilet lid 30. The recess 22 is provided in a portion of the seating surface 17 corresponding to the leg portion 34. According to this configuration, since the recess 22 is provided in the soft seating surface 17 from the beginning and the leg portion 34 of the toilet lid 30 does not cause a dent in the seating surface 17, it is difficult for the user to feel that this is a defective product. Therefore, the toilet lid 30 can be made a common component for a toilet seat with a hard seating surface and the toilet seat 10 with a soft seating surface 17.

[0027] The toilet seat 10 has a toilet seat main body portion 11 made of foamed resin. In a state where the toilet seat 10 is laid down along the upper surface of the toilet body 44, the recess 22 and the leg portion 34 do not contact each other. According to this configuration, since the leg portion 34 of the toilet lid 30 does not hit the seating surface 17, it is possible to surely prevent a dent from occurring due to the leg portion 34 hitting the seating surface 17.

[0028] The recess 22 does not contact the leg portion 34 even during the rotation of the toilet seat 10 and the toilet lid 30. According to this configuration, it is possible to surely prevent a dent from occurring due to the leg portion 34 hitting the seating surface 17.

[0029] The recess 22 is provided at the center in the left - right direction of the seating surface 17. According to this configuration, it is possible to prevent a dent from occurring in the seating surface 17 due to the leg portion 34 provided at the center in the left - right direction of the toilet lid 30.

[0030] <Embodiment 2> Next, a toilet seat 50 according to a second embodiment of the present disclosure will be described with reference to Figures 9 to 14. The toilet seat 50 of this embodiment differs from the first embodiment in that the recess 51 penetrates from the inner surface 19 to the outer surface 21 of the toilet seat body 11. Note that the same components as those in the first embodiment are given the same reference numerals and redundant explanations will be omitted.

[0031] Similar to the first embodiment, the toilet seat 50 has a toilet seat main body 11 and a toilet seat hinge part 12, the toilet seat main body 11 being made of foamed resin and the toilet seat hinge part 12 being made of hard resin. Similar to the first embodiment, the toilet seat main body 11 has a seating surface 17, a lower surface 18, an inner surface 19 and an outer surface 21. Similar to the first embodiment, a recess 51 is provided in the portion of the seating surface 17 corresponding to the leg part 34.

[0032] 10, the recess 51 extends linearly in plan view from the outer surface 21 of the front portion 13 to the inner surface 19 of the front portion 64. The left and right dimensions of the recess 51 are equal from the front side to the rear side.

[0033] The left-right dimension of the recess 51 decreases from top to bottom when viewed from the rear, as shown in Fig. 11. The recess 51 has left and right regions 52 and a bottom region 53. The left and right regions 52 gently slope from the seating surface 17 to the bottom region 53. The bottom region 53 is parallel to the underside 18 of the toilet seat main body 11. The left-right dimension of the bottom region 53 is smaller than the front-rear dimension of the front portion 13 (see Fig. 10).

[0034] In the laid-down position, the legs 34 are located above the bottom region 53, as shown in Figure 12. In the laid-down position, there is no contact between the front portion 13 and the legs 34. During rotation of the toilet seat 50 and toilet lid 30, the legs 34 do not contact the front portion 13, as shown in Figure 13. In the upright position, there is no contact between the legs 34 and the front portion 13, as shown in Figure 14.

[0035] As described above, in this embodiment, similar to Embodiment 1, the soft seating surface 17 is initially provided with the recess 51, and since the recess in the seating surface 17 does not occur due to the contact of the leg portion 34 of the toilet lid 30, it is difficult for the user to feel that this is a defective product. Therefore, the toilet lid 30 can use the same common parts for a toilet seat with a hard seating surface and a toilet seat 50 with a soft seating surface 17.

[0036] <Embodiment 3> Next, the toilet seat 60 according to Embodiment 3 embodying the present disclosure will be described with reference to FIGS. 15 to 18. The toilet seat 60 of this embodiment has a hard toilet seat main body portion 61, a soft toilet seat cover 62, and a toilet seat hinge portion 12, and is different from Embodiment 1 in that the recess 63 is provided in the toilet seat cover 62. In addition, the same components as those in Embodiment 1 are denoted by the same reference numerals, and redundant descriptions are omitted.

[0037] The toilet seat main body portion 61 is a normal toilet seat and has a general hardness. Since the toilet seat main body portion 61 does not have a heater, when the toilet seat cover 62 is not installed, it is easy for the person sitting on it to feel cold. When the toilet seat cover 62 is not installed, the leg portion 34 is in contact with the upper surface of the toilet seat main body portion 61. As a result, the toilet lid 30 is supported by the toilet seat main body portion 61.

[0038] The toilet seat cover 62 is detachably attached to the upper surface of the toilet seat main body portion 61. The toilet seat cover 62 includes a front portion 64, a rear portion 65, and left and right side portions 66, and forms an annular shape with an opening 67 formed at the center.

[0039] The toilet seat cover 62 includes a seating surface 68, a lower surface 69, an inner surface 71, and an outer surface 72. The lower surface 69 fits exactly on the upper surface of the toilet seat main body portion 61. The inner surface 71 constitutes the peripheral surface of the opening 67. The outer surface 72 faces the outside of the toilet seat cover 62.

[0040] The toilet seat cover 62 is manufactured using a material softer than the toilet seat main body portion 61. The toilet seat cover 62 has a predetermined cushioning property. The toilet seat cover 62 may be made of a foamed resin obtained by foam molding a soft resin such as polyethylene.

[0041] In the portion of the seating surface 68 corresponding to the leg portion 34, a recess 63 is provided in the same manner as in the first embodiment. The recess 63 is located at the center in the left - right direction of the front portion 64 and is formed on the rear side of the front portion 64, in the same manner as in the first embodiment. In the front portion 64, in front of the recess 63, a tip portion 73 is left. The tip portion 73 is continuously connected without a step from the left and right side portions 66 and closes the front of the recess 63 (see FIG. 17).

[0042] As shown in FIG. 16, the recess 63 has a rectangular shape in plan view. The dimension of the recess 63 in the left - right direction is equal to or slightly larger than the dimension of the leg portion 34 in the left - right direction. The recess 63 is formed from the center in the front - rear direction of the front portion 64 to the inner surface 71 of the front portion 64.

[0043] In the portion of the front portion 64 where the recess 63 is formed, as shown in FIG. 18, it is thinner and compression - hardened than the tip portion 73. In the toppled state, the front end portion of the leg portion 34 is in contact with the front end portion of the recess 63.

[0044] As described above, in the present embodiment, the toilet seat body 11 and the toilet seat cover 62 made of foamed resin installed on the upper surface of the toilet seat body 11 to form the seating surface 68 are provided, and the recess 63 is provided in the toilet seat cover 62. According to this configuration, since the recess 63 is provided in the toilet seat cover 62 from the beginning and the concave portion is compressed and hardened, when the leg portion 34 of the toilet lid 30 hits, the seating surface 68 does not dent. Therefore, it is difficult for the user to feel that this is a defective product. Thus, the toilet lid 30 can be a common part for a toilet seat with a hard seating surface and a toilet seat 60 provided with a soft toilet seat cover 62.

[0045] <Embodiment 4> Next, a toilet seat 80 according to Embodiment 4 embodying the present disclosure will be described with reference to FIGS. 19 to 22. The recess 81 of the toilet seat 80 of the present embodiment is different from that of the third embodiment in that it penetrates from the inner surface 71 to the outer surface 72 of the toilet seat cover 62. In addition, the same components as those in the third embodiment are denoted by the same reference numerals, and redundant descriptions are omitted.

[0046] The toilet seat 80 has a toilet seat main body 61 and a foamed resin toilet seat cover 62 installed on the upper surface of the toilet seat main body 61, similar to Embodiment 3, and the recess 81 is provided in the toilet seat cover 62. The toilet seat cover 62 includes a seating surface 68, a lower surface 69, an inner surface 71, and an outer surface 72, similar to Embodiment 3. The recess 81 is provided in a portion of the seating surface 68 corresponding to the leg portion 34, similar to Embodiment 3.

[0047] As shown in FIG. 20, in plan view, the recess 81 extends linearly from the outer surface 72 of the front portion 64 to the inner surface 71 of the front portion 64. The left and right dimensions of the recess 81 are equal from the front side to the rear side in plan view. The left and right dimensions of the recess 81 are equal to or slightly larger than the left and right dimensions of the leg portion 34.

[0048] As shown in FIG. 21, the formed portion of the recess 81 in the front portion 64 is compression-hardened thinner than the portion adjacent to the recess 81 in the front portion 64. In the fallen state, as shown in FIG. 22, the front end portion of the leg portion 34 contacts the rear portion of the recess 81.

[0049] As described above, in the present embodiment, similar to Embodiment 3, since the recess 81 is provided in the toilet seat cover 62 from the beginning and the recessed surface portion is compressed and hardened, the seating surface 68 does not dent when the leg portion 34 of the toilet lid 30 hits it, so the user is less likely to feel that this is a defective product. Therefore, the toilet lid 30 can be a common component for a toilet seat with a hard seating surface and a toilet seat 80 provided with a soft toilet seat cover 62.
