The present invention relates to a toilet bowl, and more particularly to a wall-mounted toilet bowl mounted on a vertical surface such as a wall. Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

In the following description, the front-back direction is determined based on the user seated on the toilet bowl 1. That is, as shown in FIG. 1, the direction in which the toilet bowl 1 protrudes from the vertical surface is forward, and the opposite direction is backward. Further, a direction parallel to the forward and backward directions is referred to as a front-rear direction, and a direction orthogonal to the front-rear direction and along the horizontal plane may be referred to as a left-right direction.

(1) Outline The toilet bowl 1 of the present embodiment is a toilet bowl 1 attached to a vertical surface such as a wall surface 70 of a toilet room. The toilet bowl 1 is arranged away from the floor surface 71, and is configured so that the floor surface 71 located below the toilet bowl 1 can be easily cleaned. On the other hand, since the toilet bowl 1 of the present embodiment is arranged at a position away from the floor surface 71, the toilet bowl body 3 is fixed to the vertical surface in order to withstand a load such as when the user is seated. Supported by. The toilet bowl 1 includes a toilet bowl main body 3 and a support frame 2.

As shown in FIGS. 2A and 3A, the support frame 2 includes a fixed body 21 and a support 20 projecting forward from the fixed body 21. The support 20 has a pair of support portions 24 extending in the front-rear direction and a pair of reinforcing portions 8. As shown in 3B, the pair of support portions 24 of the support frame 2 are configured to support the pair of mounting portions 4 of the toilet bowl body 3 on a one-to-one basis. In the mounting portion 4, the region supported by the supporting portion 24 is referred to as the mounting region 41. The mounting area 41 extends in the front-rear direction of the toilet bowl body 3. The mounting area 41 of the present embodiment includes a part of the back surface of the rim portion 33.

The mounting area 41 of the toilet bowl main body 3 of the present embodiment extends in the front-rear direction and is supported by the support frame 2 over the entire length of the mounting area 41. Therefore, the downward load applied to the toilet bowl body 3 is received by the support frame 2 via the mounting area 41 extending in the front-rear direction. Therefore, in the toilet bowl 1 of the present embodiment, a load consisting of the own weight of the toilet bowl body 3 and the weight of the user when the user is seated can be applied to the pair of support portions 24 as a distributed load. As a result, the toilet bowl 1 of the present embodiment has a structure that can withstand a load such as when the user is seated even if the toilet bowl 1 is arranged at a position away from the floor surface 71.

(2) Details Hereinafter, the toilet bowl 1 of the present embodiment will be described in detail. However, the configuration described below is merely an example of the present invention, and the present invention is not limited to the following embodiments. As long as the technical idea of the present invention is not deviated, various changes from the following embodiments can be made according to the environment and specifications of the installation site.

(2.1) Support frame The support frame 2 mounts the toilet bowl body 3 on a vertical surface. The support frame 2 is made of a member having a certain degree of rigidity or higher, and is made of, for example, a metal such as iron, stainless steel, or aluminum, carbon, wood, or the like. As shown in FIG. 2A, the support frame 2 includes a fixed body 21 and a support 20.

The fixed body 21 is configured to be fixed on a vertical surface. Here, the vertical surface is composed of the wall surface 70 of the toilet room in the present embodiment. Although the vertical surface is a vertical surface in the present embodiment, it does not mean only a strict vertical surface, and any surface along the vertical and horizontal directions is included in the category of "vertical surface". That is, the vertical surface referred to here includes a surface tilted slightly forward and a surface tilted slightly backward. Further, the vertical surface does not have to be a flat surface, and may be an uneven surface.

The fixed body 21 includes a pair of vertical bodies 22 arranged along the wall surface 70, and a horizontal body 23 connecting the pair of vertical bodies 22. The pair of vertical bodies 22 are formed of hollow pipes extending in the vertical direction and are separated from each other in the horizontal direction. The horizontal body 23 is arranged between the upper ends of the pair of vertical bodies 22 and is fixed to the pair of vertical bodies 22. The horizontal body 23 includes a fixing plate 232 and a pair of reinforcing pieces 233 protruding forward from both ends in the vertical direction of the fixing plate 232, and is formed in a substantially C-shaped cross section. The pair of reinforcing pieces 233 suppresses the deformation of the fixing plate 232. The fixing plate 232 is screwed to the wall surface 70 by a fixing tool. Examples of the fixing tool here include a screw tool 73 (see FIG. 1) such as a screw or a bolt, a rivet, a nail, or the like. The screw tool 73 has at least a shaft portion having a male screw formed on the outer periphery thereof, but may not have a head portion. Further, a flat washer and a spring washer are appropriately used as needed.

The fixing plate 232 is fixed along the wall surface 70. The fixing plate 232 is a portion extending in the left-right direction and formed in a band shape. The fixing plate 232 is formed in a plate shape.

The fixing plate 232 is provided with a plurality of fixing tool insertion holes 231. A plurality of fixing tools used for fixing to the wall surface 70 are passed one-to-one through the plurality of fixing tool insertion holes 231. The peripheral edge portion (opening peripheral edge portion 234) of each fixing tool insertion hole 231 is formed thicker than a plurality of portions other than the opening peripheral edge portions 234 in the fixing plate 232. The thickness of the opening peripheral edge portion 234 is formed to be thicker than the length of one pitch of the thread of the male screw, for example, when the fixing tool is the screw tool 73. As a result, at least two or more male screw threads are configured to hit the inner peripheral surface of the fixing tool insertion hole 231. Further, the outer diameter of the opening peripheral edge portion 234 is formed to be the same as or larger than the outer diameter of the washer of the fixing tool.

The diameter (inner diameter) of the fixing tool insertion hole 231 is formed so as to be substantially the same as the outer diameter of the shaft portion of the fixing tool. As a result, when the support frame 2 is attached to the wall surface 70, the inner peripheral surface of the fixing tool insertion hole 231 and the outer peripheral surface of the shaft portion of the fixing tool come into contact with each other or face each other in close proximity to each other and are fixed to the fixing tool insertion hole 231. It is configured so that nothing intervenes between it and the shaft of the tool.

Here, in general, in a wall-mounted toilet made of pottery, the wall surface and the toilet body made of pottery are connected by a screw tool. In this wall-mounted toilet, a cushioning material is interposed between the shaft of the screw and the inner peripheral surface of the insertion hole of the toilet body so that the threads of the screw do not come into contact with the toilet body. Is being done. For this reason, in a wall-mounted toilet made of earthenware, when the user sits on the toilet seat, the cushioning material elastically deforms, so that the toilet body moves so as to sink slightly.

On the other hand, in the toilet bowl 1 of the present embodiment, the support frame 2 which is hard to be damaged is interposed between the wall surface 70 and the toilet bowl main body 3, and comes into contact with the thread of the screw tool 73 screwed to the wall surface 70. The portion is configured to be the support frame 2. Therefore, even if a load is applied to the toilet bowl body 3, it is unlikely to be damaged or cracked. Therefore, in the toilet bowl 1 of the present embodiment, by forming the diameter of the fixing tool insertion hole 231 to be substantially the same as the outer diameter of the fixing tool, it is possible to suppress the sinking when the user is seated. ..

Further, the opening peripheral edge portion 234 of the present embodiment is formed to be thicker than a portion other than the opening peripheral edge portion 234. In other words, the contact area between the shaft portion of the fixing tool and the fixing plate 232 is configured to be a certain area or more. As a result, by using a material as thin as possible as the fixing plate 232, it is possible to disperse the external force applied to the fixing plate 232 from the fixing tool while reducing the material cost, and it is possible to suppress the destruction of the fixing plate 232.

The support 20 projects forward from the fixed body 21. The support 20 supports the toilet body 3. The support 20 includes a pair of support portions 24 and a pair of reinforcing portions 8.

The pair of support portions 24 support the toilet bowl body 3. The pair of support portions 24 project forward from the pair of vertical bodies 22 and are separated from each other in the left-right direction. The pair of support portions 24 of the present embodiment are formed so as to extend linearly in the front-rear direction.

As shown in FIG. 2B, the support portion 24 includes a vertical piece 243, an upper horizontal piece 244 protruding inward from the upper and lower ends of the vertical piece 243, and a lower horizontal piece 245.

As shown in FIG. 2A, the pair of reinforcing portions 8 support the pair of supporting portions 24 in a one-to-one correspondence. That is, each reinforcing portion 8 reinforces the corresponding supporting portion 24. Each reinforcing portion 8 is formed over a corresponding support portion 24 of the pair of support portions 24 and a corresponding vertical body 22 of the pair of vertical bodies 22, and the support portion 24 and the vertical body 22 Is fixed to. As a result, each reinforcing portion 8 maintains the relative positional relationship between the corresponding vertical body 22 and the support portion 24. Each reinforcing portion 8 of the present embodiment is composed of a brace 81.

Each brace 81 connects the lower end of one of the pair of vertical bodies 22 with the corresponding support portion 24. That is, the brace 81 located on the left side connects the lower end portion of the vertical body 22 located on the left side and the support portion 24 located on the left side. Further, the brace 81 located on the right side connects the lower end portion of the vertical body 22 located on the right side and the support portion 24 located on the right side.
