に関するものである。[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a toilet drain connection device that connects a toilet bowl and a drain pipe.

（従来の技術） 従来、此種の接続装置として既に第５図に示すものが存
在する。(Prior Art) Conventionally, this type of connection device already exists as shown in FIG. 5.

曲するようにバッキング上に外嵌合するものである。This existing product has a backing with multiple short flanges 1 on the outer circumferential surface.
At the tip of a short cylindrical main body 101 made of an elastic material provided with . The short cylindrical portion 102 has an inner cylindrical portion 103 made of the same material as the short cylindrical portion 102 at the tip thereof.
The opening rim 7 formed at the tip of the drain port 4 is inserted into the stepped portion 105 formed by the inclined surface 103, and the connecting portion 6 of the drain pipe C is connected to the outer flange. The portion 104 is bent to fit externally onto the backing.

ところが、この従来品の場合、下記の不具合がある。However, this conventional product has the following problems.

■ 主体と、それより若干大きい短筒部とを傾斜面を介
して連設してその傾斜面と主体後端縁との間に段差１０
５からなる排水口４の開口突縁７用の嵌合部を形成して

を許容するため、寸法が小さい場合に排水口４の開口突
縁７との間に隙間が生じやすく漏水を起因する虞れがあ
る。■ The main body and a slightly larger short cylindrical part are connected via an inclined surface, and there is a step 10 between the inclined surface and the rear edge of the main body.
However, since ceramic toilet bowls allow slight dimensional errors in molding accuracy, if the dimensions are small, the opening protrusion 7 of the drain port 4 may fit. A gap is likely to be formed between the edge 7 and the edge 7, which may cause water leakage.

■ その隙間の発生により排水管との接続時に捩じれ等
の変形を起因させ、漏水の危険性を増大させる。■ The gap causes deformation such as twisting when connecting to the drain pipe, increasing the risk of water leakage.

■ 主体と、それより若干大きい短筒部を傾斜面を介し
て連設すると共に短筒部の先端に内鰐部と外鍔部を設け
たものである為、形状が複雑であるばかりでなく、内周
面に段差状の嵌合部がある為、底形が面倒で且つ難しい
。■ The main body and a slightly larger short cylindrical part are connected to each other via an inclined surface, and the short cylindrical part has an inner crocodile part and an outer flange part at the tip, so it is not only complex in shape, but also Since there is a stepped fitting part on the inner peripheral surface, the bottom shape is troublesome and difficult.

■ 排水口の開口突縁と排水管の接続部との隙間が小さ
いため比較的容易に弾性変形する範囲が狭い。■ Because the gap between the opening edge of the drain outlet and the connection part of the drain pipe is small, the range in which it can be elastically deformed relatively easily is narrow.

特に開口突縁の外径が最大の場合には更に隙間は小さく
なり、外鍔部のような突出部があると排水管を嵌合する
のが困難であり無理に嵌合するとバッキングがめくれた
り、捩れたりしやすく漏水が起こりやすい。In particular, when the outer diameter of the opening edge is the largest, the gap becomes even smaller, and if there is a protruding part such as the outer flange, it is difficult to fit the drain pipe, and if it is fitted forcibly, the backing may turn over. , easy to twist and leakage.

Several mountain-shaped protruding ring pieces are provided protruding from the tip toward the leading edge, and a collar portion is provided on the opposite rear end edge to bend inward through the flat portion, so that the annular backing body is flattened. The opening edge is elastically bulged and deformed to fit outwardly into the drain port, and the connecting part is forcibly fitted outwardly to the annular backing body to connect the drain pipe.

（作 用） 本考案は平面部で便器の排水口の先端に存在する開口突

縁より内向に同一体に折曲して鍔部２を形成する。(Example) The backing body A is made of synthetic rubber or synthetic resin that has flexible elasticity, corrosion resistance, and chemical resistance, and is molded into an annular body whose inner circumferential diameter is the same over the entire length. , from approximately the center of the outer circumferential surface toward the tip edge, such that the inner circumferential surface of the connecting portion 6 of the drain pipe 3 and the outer circumferential surface of the base 5 of the drain port 4 of the toilet bowl B can be brought into close contact with each other in a compressed watertight manner. Several mountain-shaped projecting ring pieces 1 are protruded at appropriate intervals, and a flat part 3 is formed toward the opposite rear edge of the outer peripheral surface of the backing body A, and further from this rear edge. The flange portion 2 is formed by bending inwardly into the same body.

からの漏水を遮断する。The protruding ring pieces 1 are integrally molded into the annular body and projectingly provided at appropriate intervals from the approximate center of the outer circumferential surface of the backing main body A to the distal edge thereof, and have a mountain-shaped cross section, and are integrally provided on the annular body to protrude from the inner circumference of the connecting portion 6 of the drain pipe C. The surface of the toilet bowl 2 is designed so that it is clamped and pressed in an outward fitting manner between the surface and the outer circumferential surface of the concave surface portion 8 formed at the base 5 of the drain port 4 of the toilet bowl 2, so that in the event that the drain pipe C and the backing body The leakage of water from between A and A is completely prevented because the protruding ring pieces 1 are in close contact with each other at several places. Water leakage from the connection part 6 side of C is blocked.

平面部３が開口突縁７の全面に至るまで緊張密着する。The flange 2 is bent inward from the rear end edge of the backing body A so as to cover the opening edge 7 of the drain port 4.
By pushing and inserting the connecting portion 6 of the drain pipe C, the flange 2 is pulled while being covered and engaged with the opening flange 7, and accordingly, the backing body A is The flat part 3 is brought into tight contact with the entire surface of the opening edge 7.

従って、排水口４から排水される水を排水口突縁７なら
びに凹陥面部８へ漏水せしめることなく完全に排水口外
周からの漏水を防止する。Therefore, the water drained from the drain port 4 is completely prevented from leaking from the outer periphery of the drain port without causing the water to leak to the drain port flange 7 and the concave surface portion 8.

、排水管Ｃの接続部６からの水の漏出を防止する。The drain pipe C has a connecting portion 6 formed by bulging so that the opening can be inserted into the drain port 4, and the connecting portion 6 is inserted from the drain port 4 to the base while squeezing the backing body A covering the drain port 4. 5, and press the protruding ring piece 1 of the backing body A against the inner circumferential surface of the opening of the connecting portion 6, and the flange portion 2 and the flat portion 3 to the outer circumferential surface of the drain port 4. Tight pressure is applied to prevent leakage of water from the connection part 6 of the drain pipe C.

や変形することなく、漏水の原因を解消できる。(Effects of the invention) As described above, the present invention has an elastic backing body formed into an annular shape with the inner circumferential surface having the same diameter over the entire length, and the inner circumferential surface has a step caused by the presence of an inclined surface. Since there are no recesses and it is flat, even if there is a slight dimensional error in the molding accuracy of the toilet bowl, the flat part will be forcibly deformed elastically and will fit in a watertight manner without forming any gaps. Even if it is inserted for connection, it is fixed to the drain port without forming a gap due to the tension and close contact between the flange and the opening rim, so it can eliminate the cause of water leakage without twisting or deforming.

更に、バッキング本体はその内周面に凹凸部がなく平滑
面を形成しているをもって、極めてその成形が容易であ
り、且又外周面後半部が同様平滑面を形成しているので
、更に安定よく成形可能である。Furthermore, the backing body has no unevenness on its inner peripheral surface and forms a smooth surface, making it extremely easy to mold, and the second half of the outer peripheral surface also forms a smooth surface, making it even more stable. Well moldable.

する時にバッキングがめくれたり、捩れたりすることも
なく比較的容易に嵌合することができる。In addition, since the part of the backing that is in close contact with the opening rim is a flat part and bulges and deforms along the opening rim, there is only the thickness of the backing body between the opening rim and the connection part of the drain pipe.
If the outside diameter of the opening rim is the maximum, the flat part of the backing will expand and the thickness will be slightly thinner. They can be fitted relatively easily without turning over or twisting.

依って、所期の目的を遠戚できる。Therefore, the intended purpose can be a distant relative.
