  However, conventionally, the connection flange and the nut inserted into the resin flange are coupled using bolts. The bolt and nut are made of metal, and the resin flange is a resin molded product. When the bolt is turned with a tool such as a spanner, the nut pulls on the bolt head, and the nut presses the resin part of the resin flange, damaging the resin flange, which is a resin molded product. There is a problem that it becomes easy to do. In addition, the nut easily rotates together with the rotation of the bolt, so that there is a problem that the tightening of the bolt and the nut is liable to be loosened and the mounting strength of the toilet with respect to the resin flange is liable to be lowered.

  The present invention has been made in view of the above circumstances, and its object is to easily and firmly attach the connecting flange of the toilet bowl to the resin flange while reinforcing and protecting the resin flange. An object of the present invention is to provide a toilet mounting structure that can be performed.

  In order to solve the above-described problems, the present invention provides a drainage path for a bowl inside a toilet and communicates the drainage path with an external drainage pipe below the floor via a drainage member fixed to the floor side. A toilet mounting structure in which a connection flange provided at the end of a path and a resin flange provided on the outer periphery of the drainage member are coupled using a bolt and a square nut, and is attached to the upper surface of the resin flange. A mounting surface for attaching the connection flange is formed, and a side opening for inserting and holding the square nut from a side to a position below the mounting surface is formed on a side surface of the resin flange. A protective member is attached to the protective member, and the protective member is disposed in an upper piece portion that covers the upper surface of the attachment surface, a fixing portion that fixes the upper piece portion to the attachment surface, and the side opening portion. Previous A side piece for stopping rotation of the square nut by abutting against a flat part on the outer periphery of the square nut is integrally formed, and the bolt is connected to the upper piece and the mounting surface from the connection flange. And is fastened to the square nut.

  Moreover, it is preferable to provide a flat surface on the side piece of the protective member so as to come into contact with one flat surface of the outer periphery of the square nut.

  Further, the side piece of the protective member is provided with a protrusion that protrudes inward of the side opening of the resin flange, and the protrusion is connected to the outer periphery of the square nut with which the side piece contacts. It is preferable to make it contact | abut to another plane part adjacent to one plane part.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 3 shows an example of the casing 3 constituting the drainage path 5 (see FIG. 1) provided behind the bowl 2 inside the toilet bowl 1. The casing 3 is held by a holding frame body 60. In FIG. 3, 10 is a bolt, and 8 is a protective member to be described later.

  FIG. 4 shows an example of the turn trap unit 4. The turn trap portion 4 is formed of a telescopic bendable tube 4 a, and the base end of the telescopic bendable tube 4 a is connected to the discharge tube of the bowl 2. A support member 61 is fixed to the telescopic bendable tube 4a. In the support member 61, a rotary shaft 62 extending outside the turn trap portion 4 passes through a shaft hole (not shown) of the casing 3, and is shown in the figure. Not connected to the motor via a reduction gear, clutch means or the like. The support member 61 stands by with the tip of the telescopic bendable tube 4a facing upward. When cleaning the bowl 2, the tip of the telescopic bendable tube 4a is bent downward (in the direction of arrow Q in FIG. 4) by the support member 61 so as to face the drainage member 32 (see FIG. 6) at the lower end of the casing 3. As a result, the waste from the bowl 2 and the washing water are discharged from the drainage path 5 to the external drainage pipe 30 under the floor through the drainage member 32 and the horizontal pulling pipe 70.

  In addition, the external drain pipe 30 under the floor is piped below the drainage member 32 without using the horizontal pulling pipe 70, and the excrement and the wash water of the bowl 2 are passed through the bottom surface of the drainage member 32 from the drainage path 5 and below the floor. You may make it discharge | emit to the external drain pipe 30 directly.

  FIG. 5 is a perspective view of the casing 3 and the holding frame 60. In FIG. 5, the illustration of the lid 3a (see FIG. 4) of the casing 3 is omitted. A mounting hole 63 substantially equal to the outer diameter of the turn trap portion 4 is provided on the front side wall of the casing 3, and the turn trap portion 4 that can be rotated and turned upside down is inserted and attached to the mounting hole 63.

  FIG. 6 is a perspective view of the drainage member 32 accommodated in the holding frame 60. The floor fixing plate 33 at the lower end of the drainage member 32 is fixed to the floor surface 20. The outlet 32a opened in the horizontal direction of the drainage member 32 is connected to the external drainage pipe 30 under the floor via a horizontal pulling pipe 70 shown in FIG.

  On the outer periphery of the drainage hole 32 b at the upper end of the drainage member 32, a resin flange 6 is provided so that the connection flange 7 on the toilet 1 side is fastened by a bolt 10 and a square nut 9.

  FIG. 1 shows a protective member 8 attached to the resin flange 6. The resin flange 6 is formed with a mounting surface 11 on which the connecting flange 7 (see FIG. 2) on the toilet 1 side is placed, and a side opening 12 into which the square nut 9 is inserted. In addition, illustration of the connection flange 7 is abbreviate | omitted in FIG.

  In FIG. 1, hexagonal nuts 9 a and square nuts 9 j are given as examples of the square nut 9. Below, it demonstrates using the hexagon nut 9a.

  The mounting surface 11 is perforated with an upper surface opening 13 that is opened up and down through which the shaft portion 10b of the bolt 10 is inserted.

  The side opening 12 has a depth that reaches the position below the mounting surface 11 from the side surface 6 a of the resin flange 6. The hexagon nut 9a can be removably inserted into the side opening 12 from the side with the hole 9b facing upward. The hexagonal nut 9 a is held at a position on the back side of the side opening 12 and facing the lower side of the upper surface opening 13 of the mounting surface 11. At this time, the lower surface of the hexagon nut 9 a is supported by the left and right bottom walls 12 b in the side opening 12.

  FIG. 2 shows a state in which the connection flange 7 and the resin flange 6 are connected and fixed using the protection member 8. The protection member 8 is attached to the resin flange 6. The protective member 8 of this example is made of a sheet metal part bent into a groove shape. The protective member 8 includes an upper piece portion 14, a fixing portion 15, and a side piece portion 16 that are integrally formed.

  The upper piece 14 is placed so as to cover the surface of the mounting surface 11 of the resin flange 6. On the center side of the upper piece portion 14, a hole portion 17 through which the shaft portion 10 b of the bolt 10 can be inserted is formed at a position facing the upper surface opening portion 13 of the mounting surface 11.

  The fixing portion 15 is bent in a rib shape downward from one end of the upper piece portion 14. On the other hand, a slit groove 18 is formed on the mounting surface 11 of the resin flange 6 at a position opposite to the side surface 6a of the resin flange 6 with the upper surface opening 13 interposed therebetween. The slit groove 18 opens upward and extends in parallel with the side surface 6a of the resin flange 6, so that the rib-shaped fixing portion 15 of the protection member 8 can be fitted from above.

  The side piece 16 is formed in a flat plate shape that is bent downward from the other end of the upper piece 14. The side piece 16 is disposed at a position to close the side opening 12 of the resin flange 6, and has a flat surface 16a that abuts on a flat surface portion 9c of the outer periphery of the hexagon nut 9a. In this example, the flat side piece 16 is flattened on the near flat surface 9c in a state where the flat surface 9d on the back side of the outer periphery of the hexagon nut 9a is abutted against the wall surface 12a on the far side of the side opening 12. The surface 16a comes into contact. As a result, the hexagonal nut 9a is prevented from rotating around its hole 9b and is also prevented from moving back and forth. Further, the left and right corners 9e and 9f of the hexagon nut 9a are in contact with the left and right inner walls 19a and 19b of the side opening 12, respectively, and the left and right movement of the hexagon nut 9a is also prevented.

  Next, an example of the procedure for installing the toilet 1 will be described.

  Prior to installation of the toilet 1, the hexagon nut 9 a is inserted from the side opening 12 of the resin flange 6 in the direction indicated by the arrow A in FIG. 1 and held at a position below the upper surface opening 13 of the mounting surface 11. On the other hand, an adhesive tape (not shown) is attached to the back surface of the upper piece portion 14 of the protective member 8 and adhered to the upper surface of the mounting surface 11 of the resin flange 6, and in the direction indicated by the arrow B in FIG. Is inserted into the slit groove 18. At this time, the side piece 16 is arranged in a direction covering the side opening 12 of the resin flange 6 in the direction indicated by the arrow C in FIG. At this time, as shown in FIG. 2, the flat surface 16a of the side piece 16 is in contact with the one flat surface portion 9c in front of the outer periphery of the square nut 9a.

  Next, the toilet 1 is lifted and the toilet 1 is placed on the floor surface 20 while the connecting flange 7 and the resin flange 6 of the toilet 1 are aligned. As a result, as shown in FIG. 2A, the connection flange 7 is placed on the upper surface of the upper piece 14 of the protection member 8 mounted on the mounting surface 11 of the resin flange 6.

  Thereafter, with the side cover (not shown) constituting the outline of the toilet bowl 1 removed, the connection flange 7 and the resin flange 6 located inside from the outside of the toilet bowl 1 are fastened with bolts 10. That is, as shown in FIG. 1, the shaft portion 10 b of the bolt 10 is inserted into the bolt insertion hole (not shown) of the connection flange 7 (see FIG. 2A) via the washer 22. Further, the shaft portion 10b is sequentially inserted from the hole portion 17 of the upper piece portion 14 of the protective member 8 into the upper surface opening portion 13 of the mounting surface 11 of the resin flange 6 and screwed into the hole 9b of the hexagon nut 9a. FIG. 2A shows a state in which the shaft portion 10b of the bolt 10 is fastened to the square nut 9a with the head portion 10a of the bolt 10 protruding above the connection flange 7. FIG.

  At this time, when the bolt 10 is tightened with a tool such as a spanner (not shown), a force G to be pulled upward is applied to the hexagon nut 9a as shown in FIG. Accordingly, an upward pulling force F acts on the mounting surface 11 of the resin flange 6, but the mounting surface 11 is pressed from above by the upper piece 14 of the protective member 8, so that the mounting surface 11 is configured. The resin part to be made becomes difficult to lift upward. Thereby, the resin flange 6 which is a resin molded product is reinforced by using the protection member 8 of the sheet metal product, and the resin is hardly damaged.

  Further, when the bolt 10 is rotated and tightened, as shown in FIG. 2B, the flat surface 16a of the side piece 16 abuts against one flat surface portion 9c of the outer periphery of the hexagon nut 9a, so that the hexagon nut 9a. Becomes difficult to rotate in the direction indicated by the arrow N in FIG. As a result, the bolt 10 and the hexagonal nut 9a can be tightened firmly and effortlessly. As a result, the mounting strength of the toilet 1 can be increased, and workability is improved.

  Not only when the toilet 1 is installed, but also when the toilet 1 is removed, the protective function of the resin flange 6 by the protective member 8 and the co-rotation preventing function of the hexagon nut 9a are exhibited.

  Further, since the protective member 8 of this example is made of a sheet metal part bent into a groove shape, there is an advantage that the manufacturing cost can be kept low.

  Further, the entire protective member 8 can be fixed so as not to move relative to the resin flange 6 simply by forming the fixing portion 15 of the protection member 8 into a rib shape and fitting it into the slit groove 18 of the resin flange 6. Accordingly, there is an advantage that the protection member 8 can be fixed relatively easily.

  FIG. 7 shows another embodiment, and two projecting portions 25 and 26 projecting from both ends of the side piece 16 of the protective member 8 toward the inner side M of the side opening 12 of the resin flange 6 are shown. It is protruding. These projecting portions 25 and 26 are brought into contact with another flat surface portion 9g and 9h adjacent to one flat surface portion 9c of the outer periphery of the hexagon nut 9a with which the side piece portion 16 is in contact. Here, the two protruding portions 25 and 26 are illustrated, but one protruding portion 25 (or 26) may be protruded from one end of the side piece portion 16. Other configurations are the same as those in FIG. 2, and corresponding portions are denoted by the same reference numerals and detailed description thereof is omitted.

  In this example, one protrusion 25 protruding from the side piece 16 abuts one flat surface 9g adjacent to the one flat surface 9c of the outer periphery of the hexagon nut 9a, and the other protrusion 26 contacts the other flat surface 9h. It is in contact. As a result, the side piece 16 and the two protrusions 25 and 26 come into contact with the three flat portions 9c, 9g, and 9h, respectively, thereby further enhancing the effect of preventing the joint rotation of the hexagon nut 9a. It becomes. In the example of FIG. 7, the flat surface 16a of the side piece portion 16 is in contact with the one flat surface portion 9c of the hexagon nut 9a, but the hexagonal nut 9a is not in contact with the flat surface portion 9c. It is possible to stop the rotation of the nut 9a.

  Further, since the protective member 8 only has the rib-shaped fixing portion 15 fitted in the slit groove 18 of the resin flange 6, the protective member 8 is located above the resin flange 6 before or during the installation of the toilet 1. It becomes easy to leave. However, in this example, the rotation-preventing projections 25 and 26 provided on the side piece 16 protrude toward the inner side M of the side opening 12, respectively, so that the side piece 16 can be prevented from coming off. Function. That is, when the fixing portion 15 is about to come out above the slit groove 18, the protrusions 25 and 26 are caught on the top surface portion 12 e of the side surface opening portion 12. As a result, the side piece 16 is less likely to be pulled upward in the direction indicated by the arrow Q in FIG. 7C, and the advantage that the protective member 8 is difficult to be detached from the flange 6 is obtained.
