BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for connecting a defecation pipe communicating with sewage and the like and an outlet of a defecation passage of a toilet via a drainage flange and a soft packing.

[0002]

2. Description of the Related Art A conventional structure for connecting a defecation pipe, which is connected to sewage or the like, and an outlet of a defecation passage of a toilet bowl, is as shown in a vertical sectional view of FIG. As shown in the figure, a defecation pipe 2 which is connected to a sewer pipe or the like when building a building body is vertically embedded in a floor 1 of a toilet room. In addition, the defecation tube 2 is provided with a VP1 depending on the purpose of use.
00, VU100, VP75, VU75, there are four different diameter pipes with different diameters.

A cylindrical portion 3a of a drainage flange 3 is fitted on the inflow port side of the defecation pipe 2 which opens into the toilet room. The flange portion 4 of the drainage flange 3 is fixed to the floor 1 via a mounting screw 5. Further, on the upper surface of the flange portion 4 of the drainage flange 3, a gasket 6 which is self-adhesive and made of unvulcanized butyl rubber that is compositionally deformed is placed.
The outlet 9 of the defecation passage 8 formed integrally with the toilet 7 is placed on the gasket 6 made of unvulcanized butyl rubber so as to be aligned with the inlet side of the defecation pipe 2.

Further, a T bolt 10 for fixing a toilet is fitted and mounted on the drainage flange 3 and protrudes upward. By inserting the T-bolt 10 into the upper surface side of the leg 11 of the toilet bowl 7 and screwing and fastening the nut 12, the toilet bowl 7 is fixed and the outlet 9 of the defecation passage 8 and the inlet of the defecation tube 2 are connected. I am trying to establish a communication connection. In addition, 13 is a nut 1
2 is a cosmetic cap for concealing the bolt 2 and the bolt 10.

As described above, in the conventional connection structure of the drainage flange 3, the tubular portion 3a of the drainage flange 3 is fitted in the inlet side of the defecation pipe 2, and the flange portion 4 of the drainage flange 3 is fitted.
A gasket 6 made of unvulcanized butyl rubber is interposed between the container and the toilet 7 side to maintain watertightness. By the way, in the defecation tube 2, VP100, VU100, VP75, VU
As described above, there are 75 types of different diameter pipes. The VP100 has an outer diameter of 114 mm and an inner diameter of about 100 m.
m, VU100 has an outer diameter of 114 mm and an inner diameter of about 107 m
m, VP75 has an outer diameter of 89 mm and an inner diameter of approximately 77 mm, VU
75 has an outer diameter of 89 mm and an inner diameter of about 83 mm.

With respect to such a different diameter pipe, the size of the outlet 9 of the defecation passage 8 of the toilet 7 and the size of each part of the drainage flange 3 are constant. Therefore, in the prior art, when connecting the drainage flange 3 to the four types of different diameter pipes, an adapter 14 is interposed between the drainage flange 3 and the defecation pipe 2 as shown in FIG. I was trying to establish a communication connection. The adapter 14 has an inner tubular portion 15 and an outer tubular portion 16 that are continuous on the upper end side, the VU 100 is externally fitted and joined to the outer circumferential surface of the outer tubular portion 16, and the VU 75 is externally fitted to the outer circumferential surface of the inner tubular portion 15. It is joined.

Therefore, in the conventional structure in which the defecation pipe 2 and the defecation passage outlet 9 of the toilet 7 are connected via the drainage flange 3, the adapter 14 is a double cylinder having an inner tubular portion 15 and an outer tubular portion 16. In addition, it is necessary to prepare at least two types of adapters 14 of different sizes to accommodate the four types of different diameter pipes, and the manufacturing control and selection at the time of construction become extremely complicated. It had drawbacks.

In view of this, by using the packing 17 composed of the tubular portion 18 and the collar portion 19 as shown in FIGS. 6 and 7, even if there is only one type of defecation, each different diameter defecation is performed. The technology that can be connected to the pipe 2 is 3 November 1994.
Filed on 0th. According to this prior application, the outer diameter of the tubular portion 3a of the drainage flange 3 is made to match the inner diameter of the smallest VP 75 of the four types of defecation pipe 2 of about 77 mm, and the larger VU75, VP100, VU
In the case of 100 defecation pipe 2, the packing 17 having the collar portion 19 is used to remove the gap size between the tubular portion 3a of the drainage flange 3 and the defecation pipe 2 and thereby the collar portion 19 This is to ensure the sealing property. The packing 17 is made of soft vinyl chloride or the like.

[0009]

However, in the technique of the prior application shown in FIGS. 6 and 7, the VU 100 and the VU 100 are used.
When connecting the defecation pipe 2 and the drainage flange 3 of P100, the gap between the defecation pipe 2 and the cylindrical portion 3a of the drainage flange 3 becomes too large, and the center line of the drainage flange 3 side and the defecation pipe 2 side In some cases, the two were fitted together with the center line displaced. This fitting state cannot be visually confirmed from the toilet 7 side.

Therefore, when they are fitted with their center lines displaced, the tubular portion 3a of the drainage flange 3 and the defecation pipe 2
And the packing 17 is unevenly mounted between them, and a region where the flange portion 19 is not joined to both the defecation pipe 2 and the tubular portion 3a of the drainage flange 3 is formed or the joining is not performed. There is a drawback that a sufficient area is formed and sewage or odor may leak into the toilet room from the area.

DISCLOSURE OF THE INVENTION The present invention has been made by improving and removing the above problem in view of the above-mentioned conventional problem, and the connection is made without using an adapter having a double cylinder structure and in a state where the center lines are aligned. The purpose of the present invention is to provide a connection structure between a toilet bowl and a defecation tube of different diameter.

The means adopted by the present invention in order to solve the above-mentioned problems are as follows:
A device for connecting an outlet of a defecation passage of a toilet bowl via a drainage flange, wherein the tubular part is formed between the defecation pipe and the drainage flange and protrudes from the lower end side of the tubular part in the outer diameter direction. A toilet bowl having a thick bulging portion and a soft packing having an annular tongue protruding further outward in the radial direction from the bulging portion to accommodate a different diameter of the defecation canal. And a different diameter defecation tube.

[0013]

According to the present invention, a soft slab having a thick bulge projecting outward from the lower end of the tubular portion and an annular tongue projecting outward from the bulge. A packing is prepared, and the packing is interposed between the outer surface of the cylindrical portion of the drainage flange and the inner peripheral surface of the defecation tube.

If the center lines of the defecation pipe and the drainage flange do not coincide with each other, the bulging portion interferes and the packing cannot be loaded. Therefore, in the state where the defecation pipe and the drainage flange are connected with the packing interposed, the center lines of the three members are necessarily aligned. At this time, the soft annular tongue of the packing is uniformly pressed over the entire peripheral surface in the gap portion between the drainage flange and the defecation pipe, thus performing a reliable seal.

[0015]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The structure of the present invention will be described below with reference to the embodiments shown in the drawings. The same reference numerals as in the conventional case are the same members. 1 to 3 relate to an embodiment of the present invention and are shown in FIGS. 1 (a) to 1 (d).
2 is a partial vertical cross-sectional view showing a connection structure with different diameter defecation pipes, FIG.
Is a longitudinal sectional view showing the packing 20 for the VU75, and FIG.
It is a longitudinal section showing packing 21 for P100 and VU100.

In this embodiment, the outer diameter of the cylindrical portion 3a of the drainage flange 3 is set as shown in FIG.
It is manufactured according to the inner diameter of about 77 mm of the smallest VP 75 of the four types of defecation pipes 2. In this case, the cylindrical portion 3a of the drainage flange 3 may be directly fitted in the inner peripheral surface of the defecation pipe 2 in a close contact state.

Thus, a VU having an inner diameter of about 83 mm, which is larger than the outer diameter of the cylindrical portion 3a of the drainage flange 3.
In the case of 75 defecation tube 2, packing 20 as shown in FIG. 2 is used. The packing 20 has a tubular portion 22 and an annular tongue piece 23 protruding from the lower end side of the tubular portion 22 in the outer diameter direction, and is made of soft vinyl chloride or the like. In addition, the drainage flange 3 and the defecation pipe 2
Are usually molded from rigid vinyl chloride.

To connect the drainage flange 3 and the defecation pipe 2 of the VU 75, first apply a vinyl chloride adhesive to the outer peripheral surface of the tubular portion 3a of the drainage flange 3 and the inner peripheral surface of the defecation pipe 2.
The tubular portion 22 of the packing 20 is replaced by the tubular portion 3 of the drainage flange 3.
It is fitted on the outer peripheral surface of a. Then, in this state, FIG.
(B), the annular tongue piece 23 of the packing 20 is fitted and attached to the inner peripheral surface of the defecation tube 2, and the upper end surface of the defecation tube 2 contacts the lower surface side of the flange portion 4 of the drainage flange 3. Insert to the position.

As a result, the annular tongue piece 23 of the packing 20 is
Is interposed between the tubular portion 3a of the drainage flange 3 and the defecation tube 2 in an elastically folded state, and the packing tubular portion 22 has an outer peripheral surface of the tubular portion of the drainage flange 3. And the annular tongue piece 23 is bonded to the defecation tube 2
Is adhered to the inner peripheral surface of. That is, the elastic sealing effect of the soft packing 20 and the adhesive sealing effect of the adhesive can be obtained, and extremely high sealing performance can be obtained.

When the defecation tube 2 has a VU100 with an inner diameter of about 107 mm and an outer diameter of 114 mm and when the defecation tube 2 has a VP100 with an inner diameter of about 100 mm and an outer diameter of 114 mm, as shown in FIG. A bulged portion 24 protruding in the outer diameter direction is formed on the lower end side of the ridge-shaped portion 22, and the bulged portion 24 is further formed.
The packing 21 in which the annular tongue piece 23 protruding from the outer radial direction is formed may be used.

In the case of these VU100 and VP100, a large gap is generated between the drainage flange 3 and the defecation pipe 2 as shown in FIGS. There is fear. However, when the packing 21 is used, the packing 21 is attached to the center line of the defecation tube 2.
If the center line of the drainage flange 3 fitted to the outside does not match, the bulging portion 24 interferes and the charging becomes impossible.

Therefore, the center lines of the drainage flange 3, the packing 21, and the defecation tube 2 inevitably coincide with each other, and the annular tongue piece 23 is elastically pressed against the inner peripheral surface of the defecation tube 2. A reliable seal is obtained.

[0023]

As described above, according to the present invention,
A soft packing provided with a thick bulge protruding from the lower end side of the tubular portion in the outer diameter direction and an annular tongue protruding further from the bulge in the outer diameter direction is prepared. Since the outer surface of the cylindrical portion of the above and the inner peripheral surface of the defecation tube are arranged to intervene, when the center lines of the defecation tube and the drainage flange do not match, the bulged portion interferes. The packing cannot be loaded. Therefore, in the state where the defecation pipe and the drainage flange are connected with the packing interposed, the center lines of the three members inevitably coincide with each other, and no misalignment occurs, so the soft annular tongue of the packing is The gap between the drainage flange and the defecation pipe is pressed uniformly over the entire peripheral surface, and reliable sealing is possible.
