従来例のような接続構造は、以下のような問題点があった。
図１３の従来例では、槽体の表面側から向かって雄ねじを目皿部材の貫通孔に挿通させて、本体部の雌ねじ受け部に螺合させるので、槽体の表面側から雄ねじの頭部分が露出してしまい、外観上意匠性が非常に悪かった。
また、図１４の従来例では、取付ガイドをわざわざ槽体の裏面に溶着せねばならないので、取付作業が非常に手間であった。
また、図１５の従来例では、雄ねじを使用しないことや、取付ガイドのようなものを槽体裏面にわざわざ取り付けないでもよいのでメリットはあるが、オーバーフローフランジと本体部の取付をねじ螺合による接続としているため、オーバーフローフランジ及び本体部を円形状にせねばならないので、槽体の取付口の形状の選択の幅が狭く、使用者によっては意匠性が非常に悪いと感じられる場合もあった。
また、図１６の従来例では、取付口と本体部の取付をねじ螺合による接続としているため、取付口及び本体部、ナット部材を円形状にせねばならないので、槽体の取付口の形状の選択の幅が狭く、使用者によっては意匠性が非常に悪いと感じられる場合もあった。
また、図１７の従来例では、取付口と本体部の取付を、槽体裏面から雄ねじと雌ねじによるねじ接続としているため、雄ねじを槽体の裏面に直接的に接続せねば成らず、槽体の裏面に雌ねじを刻設することが必要であった。このような作業は非常に手間である上、槽体に直接的に雌ねじを刻設するので、槽体が金属の薄板状の素材であったり、大理石などの脆い素材であった場合には雌ねじが刻設できないので、そういった素材の槽体には取り付けることは出来なかった。 The connection structure as in the conventional example has the following problems.
In the conventional example of FIG. 13, the male screw is inserted into the through hole of the countersink member from the surface side of the tank body and screwed into the female screw receiving portion of the main body portion. Was exposed, and the design was very poor in appearance.
Further, in the conventional example shown in FIG. 14, the mounting guide has to be welded to the back surface of the tank body, so that the mounting work is very troublesome.
Further, in the conventional example of FIG. 15, there is a merit because it is not necessary to use a male screw or to attach an attachment guide or the like to the rear surface of the tank body. Since it is connected, the overflow flange and the main body must be circular, so the range of selection of the shape of the mounting opening of the tank body is narrow, and some users may feel that the design is very poor.
In addition, in the conventional example of FIG. 16, since the attachment port and the main body are attached by screw threading, the attachment port, the main body, and the nut member must be circular. The range of selection was narrow, and some users felt that the design was very poor.
Moreover, in the conventional example of FIG. 17, since the attachment port and the main body portion are attached by screw connection with a male screw and a female screw from the rear surface of the tank body, the male screw must be directly connected to the rear surface of the tank body. It was necessary to engrave an internal thread on the back side of the. Such work is very troublesome and the internal thread is directly engraved in the tank body, so if the tank body is a thin metal plate material or a brittle material such as marble, the internal thread Could not be engraved, so it could not be attached to a tank of such material.

１．使用者が外観視できる槽体の表面側の意匠性が良い接続構造。
２．取付作業が簡単である接続構造。

The drainage channel 16 is a channel connected from the main body 11 connected to the attachment port 1 and is finally connected to the sewer pipe. Moreover, it is a pipe body for discharging the waste water in the tank body 13 to the sewer pipe finally.

このように構成された接続構造は以下のように接続される。
カバー体５の筒部２に第１止水パッキン６を配置させ、槽体１３の取付口１に、槽体１３の表面側からカバー体５の筒部２を挿入し、カバー体５のフランジ部３を、第１止水パッキン６を介して取付口１周縁に係止させる。そして、槽体１３の裏面からカバー体５の筒部２外周に第２止水パッキン７を配置させ、槽体１３の裏面から飛び出しているカバー体５の筒部２に、本体１１の受け部９を挿入する。このとき、第２止水パッキン７の凸部８は本体１１の受け部９に水密的に当接させるように、また、本体１１の貫通孔１０はカバー体５の雌ねじ部４に合致するようにそれぞれ挿入する。そして、槽体１３の裏面から、雄ねじ体１２を、本体１１の貫通孔１０に挿通させ、貫通孔１０に合致するように配置されたカバー体５の雌ねじ部４に螺合させる。そうすると、本体１１は雄ねじ体１２とカバー体５に挟まれるように雄ねじ体１２の締め付けによりカバー体５と接続される。また、同時に雄ねじ体１２の締め付けにより、槽体１３の取付口１はカバー体５のフランジ部３と本体１１の受け部９に挟持されるように接続される。そして、槽体１３の取付口１にカバー体５・本体１１を接続することが出来る。このとき、カバー体５のフランジ部３と槽体１３の取付口１周縁は第１止水パッキン６により水密化されているので漏水することがなく、また、カバー体５と本体１１の間には第２止水パッキン７が介在して水密化しているので漏水することがない。このように接続することで、槽体１３に簡単に接続することが出来るし、槽体１３の取付口１に直接的に雌ねじを刻設することもなく、槽体１３の表面側から雄ねじ体１２の頭が露出するようなこともなく、また、取付口１の形状を丸形以外の形状とすることができる。また、第２止水パッキン７の外周に凸部８を構成したからより水密性が向上することとなった。
また、本体１１の下流には、排水管及び排水トラップを接続し、最終的には排水流路１６と接続するように配管される。 The connection structure configured in this way is connected as follows.
The first water-stopping packing 6 is disposed in the cylindrical portion 2 of the cover body 5, the cylindrical portion 2 of the cover body 5 is inserted into the attachment port 1 of the tank body 13 from the surface side of the tank body 13, and the flange of the cover body 5 The portion 3 is locked to the periphery of the attachment port 1 via the first water-stop packing 6. And the 2nd water stop packing 7 is arrange | positioned from the back surface of the tank body 13 to the cylinder part 2 outer periphery of the cover body 5, and the receiving part of the main body 11 is provided in the cylinder part 2 of the cover body 5 protruding from the back surface of the tank body 13 9 is inserted. At this time, the convex portion 8 of the second waterstop packing 7 is brought into watertight contact with the receiving portion 9 of the main body 11, and the through hole 10 of the main body 11 is matched with the female screw portion 4 of the cover body 5. Insert into each. Then, the male screw body 12 is inserted into the through hole 10 of the main body 11 from the back surface of the tank body 13 and screwed into the female screw portion 4 of the cover body 5 arranged so as to match the through hole 10. Then, the main body 11 is connected to the cover body 5 by tightening the male screw body 12 so as to be sandwiched between the male screw body 12 and the cover body 5. At the same time, when the male screw body 12 is tightened, the attachment port 1 of the tank body 13 is connected so as to be sandwiched between the flange portion 3 of the cover body 5 and the receiving portion 9 of the main body 11. And the cover body 5 and the main body 11 can be connected to the attachment port 1 of the tank body 13. At this time, the flange portion 3 of the cover body 5 and the periphery of the attachment port 1 of the tank body 13 are watertight by the first water-stopping packing 6, so that no water leaks, and between the cover body 5 and the main body 11. Since the second water-stopping packing 7 is interposed and watertight, there is no water leakage. By connecting in this way, it can be easily connected to the tank body 13, and a male screw body is formed from the surface side of the tank body 13 without engraving a female screw directly in the mounting port 1 of the tank body 13. The 12 heads are not exposed, and the shape of the attachment port 1 can be a shape other than a round shape. Moreover, since the convex part 8 was comprised in the outer periphery of the 2nd water stop packing 7, watertightness will improve more.
Further, a drain pipe and a drain trap are connected downstream of the main body 11 and finally piped so as to be connected to the drain channel 16.

このような実施例の接続構造においては、以下のような排水の流れとなる。
槽体１３内に排水が発生すると、槽体１３底面に開口された取付口１から排水が槽体１３裏面に取り付けられた本体１１内へ流入する。本体１１内の排水は、排水流路１６へと排出され、排水トラップを介して最終的には下水管へと排出される。 In the connection structure of such an embodiment, the flow of drainage is as follows.
When drainage occurs in the tank body 13, the drainage flows into the main body 11 attached to the rear surface of the tank body 13 from the attachment port 1 opened on the bottom surface of the tank body 13. The drainage in the main body 11 is discharged to the drainage channel 16 and finally discharged to the sewer pipe through the drainage trap.

また、本発明の実施例は上記に記載した実施例のほかにも、特許請求の範囲を逸脱しない範囲で適宜変更が可能である。
例えば前記実施例では洗面ボウルのオーバーフロー用流路１５や排水流路１６に用いる接続構造であるが、例えば台所の流し台やトイレのタンク配管などに用いられてもかまわない。 In addition to the embodiments described above, the embodiments of the present invention can be modified as appropriate without departing from the scope of the claims.
For example, in the above-described embodiment, the connection structure is used for the overflow flow path 15 and the drain flow path 16 of the wash bowl, but it may be used, for example, for a kitchen sink or a toilet tank pipe.

また、本実施例では、カバー体５に雌ねじ部４を刻設し、雄ねじ体１２と螺合しているが、カバー体５に雄ねじ、本体１１にナットなどの雌ねじを刻設して、両者を螺合させて接続しても良い。 In the present embodiment, the female thread portion 4 is engraved on the cover body 5 and screwed with the male thread body 12. However, both the male thread 11 is engraved on the cover body 5 and the female thread such as a nut is engraved on the main body 11. May be connected by screwing.
