Description

【０００１】
【発明の属する技術分野】
本発明は、家屋の軒先の入隅部に設けられる軒樋と曲り継手の接続構造で、軒樋と曲り継手とに屋外側側壁のほぼ中央部に内方に向けて溝部が設けられている軒樋と曲り継手の接続構造に関する。
【０００２】
【従来の技術】
従来、軒先の入隅部で軒樋同士を接続する曲り継手としては、例えば、実開平７−３１７２４２号公報に記載されているものがある。
この実開平７−３１７２４２号公報の曲り継手は、断面形状が略Ｌ字型に形成された曲り継手本体と、この曲り継手本体の入隅部の屋外側側壁のほぼ中央部に内方に向けて曲り継手溝部と、この曲り継手溝部に上向きに水返し片と、両端部に軒樋が接続可能な軒樋接続部とが設けられているものである。
【０００３】
この実開平７−３１７２４２号公報記載の曲り継手では、曲り継手本体の屋外側側壁が、上部と、中央部と、下部との３つのパーツからなり、それぞれを分割して成型し、後で各パーツを結合させるものであり、３つのパーツとして金型を小型化して金型製作費を押え、上部のみを複数種類成型するだけで、曲り継手のデザインの多様化を図ったりすることができるもので、簡単な構造で、使い易いものである。
【０００４】
又、水返し片に軒先から流れ落ちる雨水が当たって、曲り継手本体内に跳ね返され、継手溝部から外に雨水がしみ出したりしない曲り継手である。
【０００５】
【発明が解決しようとする課題】
ところが、上記の実開平７−３１７２４２号公報記載の曲り継手では、曲り継手本体の屋外側側壁が、上部と、中央部と、下部との３つのパーツからなっているため、上部と、中央部と、下部とを小型化しても、それぞれ別々に金型を作ったり、保管したりせねばならず、金型製作費や保管や保守がかかりコストアップになるという問題があった。
【０００６】
又、上記の曲り継手では軒樋溝部からの流れてきた雨水を曲り継手内へ流すことができないので、軒先から流れ落ち、屋外側側壁を伝わって軒樋溝部に流れこみ、軒樋溝部に溜まった雨水は溢れ、軒樋を伝わって下に落ちたり、後が付いて汚れたりするという問題があった。
【０００７】
そこで、本発明の目的は、上記のような問題に着目し、曲り継手の製作費や保管や保守にかかるコストを削減し、軒樋溝部からの流れてきた雨水を曲り継手内へ流して、雨水が下に落ちたり、軒樋が汚れたりしない軒樋と曲り継手の接続構造を提供するものである。
【０００８】
【課題を解決するための手段】
本発明は上記の目的を達成するためになされたもので、請求項１記載の発明は、軒樋が曲り継手に接続された軒樋と曲り継手の接続構造において、軒樋は、断面形状が略Ｕ字形になされ、屋外側側壁の上端部に屋外側耳部とほぼ中央部に軒樋溝部と、屋内側側壁の上端部に屋内側耳部とが軒樋の長手方向に沿って設けられ、曲り継手は、断面形状が略Ｌ字型になされた曲り継手本体と、この曲り継手本体の入隅部の屋外側側壁のほぼ中央部に内方に向けて曲り継手溝部と、この曲り継手溝部を曲り継手本体の内方より覆う覆材と、両端部に軒樋が接続可能な軒樋接続部とが設けられ、軒樋の端部が、曲り継手本体の軒樋接続部に接続され、軒樋溝部が曲り継手溝部に嵌め込まれ、軒樋の端縁と覆材の軒樋接続部側の端縁とが当接し、曲り継手溝部の外周面の下面と軒樋溝部の内周面の下面との間に間隙部と、軒樋溝部の下端縁と覆材の下端縁との間に開口部とが設けられ、間隙部と開口部とが連通されているものである。
【０００９】
請求項２記載の発明は、軒樋が曲り継手に接続された軒樋と曲り継手の接続構造において、軒樋は、断面形状が略Ｕ字形になされ、屋外側側壁の上端部に屋外側耳部とほぼ中央部に軒樋溝部と、屋内側側壁の上端部に屋内側耳部とが軒樋の長手方向に沿って設けられ、曲り継手は、断面形状が略Ｌ字型になされた曲り継手本体と、この曲り継手本体の入隅部の屋外側側壁のほぼ中央部に内方に向けて曲り継手溝部と、この曲り継手溝部を曲り継手本体の内方より覆う覆材と、両端部に軒樋が接続可能な軒樋接続部とが設けられ、軒樋の端部が、曲り継手本体の軒樋接続部に接続され、軒樋溝部が曲り継手溝部に嵌め込まれ、軒樋溝部の端部が曲り継手溝部と覆材の間に差し込まれ、曲り継手溝部の外周面の下面と軒樋溝部の内周面の下面との間に上側間隙部と、軒樋溝部の外周面の下面と覆材の内周面の下面との間に下側間隙部とが設けられ、上側間隙部と下側間隙部とが連通されているものである。

【００１１】
請求項１記載の発明において、覆材を設ける場所と形状は、軒樋の端部が曲り継手本体の軒樋接続部に差し込まれ、軒樋の端縁と覆材の軒樋接続部側の端縁とが当接させることができれば、適宜な場所でよく、例えば、図１に示すように、曲り継手本体の屋外側側壁の内側のほぼ中央部で、Ｌ字型のコーナー部から両方向の軒樋接続部側に向けて、曲り継手溝部の形状に合わせた断面形状がコ字型の覆材をコ字型の開口部を曲り継手本体の屋外側側壁に向け、屋外側側壁に両端を取り付けて、覆材を設けておくと、成型し易いので、好ましい。
又、覆材の表面を凹凸状にしておくと、雨水が覆材の表面に当たっても跳ねたりしないし、覆材の軒樋接続部側の端縁から軒樋接続部側に向けて軒樋溝部の形状に合わせて庇部を設けておくと、開口部から外側に雨水がでるのをふせぐことができるので、好ましい。
【００１２】
請求項２記載の発明において、軒樋溝部と、曲り継手溝部と、覆材とは、曲り継手本体内で、軒樋溝部が曲り継手溝部に嵌め込まれ、曲り継手溝部が覆材で覆われ、軒樋溝部の端部が曲り継手溝部と覆材の間に差し込まれ、曲り継手溝部の外周面の下面と軒樋溝部の内周面の上面との間に上側間隙部と、軒樋溝部の外周面の下面と覆材の内周面の下面との間に下側間隙部とが設けられ、上側間隙部と下側間隙部とが連通されていいれば、適宜な構造でよく、例えば、図５に示すように、軒樋溝部の大きさを曲り継手溝部より大きくし、軒樋溝部を曲り継手溝部と覆材の間に差し込み、曲り継手溝部の外周面の下面と軒樋溝部の内周面の下面とで上側間隙部を作り、覆材の大きさを軒樋溝部より大きくし、覆材を軒樋溝部に被せ、軒樋溝部の端部を曲り継手溝部と覆材の間に差し込み、軒樋溝部の外周面の下面と覆材の内周面の下面で下側間隙部を作り、上側間隙部と下側間隙部とが連通するようにしておくと、図６に示す矢印ように、軒樋溝部に流れ込んだ雨水は、曲り継手溝部の外周面の下面と軒樋溝部の内周面の下面とでできた上側間隙部と通り、軒樋溝部の外周面の下面と覆材の内周面の下面との間に下側間隙部を通り、曲り継手本体内へ流れ込むので、軒樋溝部に雨水が溜まり、雨水が下に落ちたり、軒樋が汚れたりすることがない。
【００１３】
請求項２記載の発明において、覆材を設ける場所と形状は、軒樋の端部が曲り継手本体の軒樋接続部に接続され、軒樋溝部が曲り継手溝部に嵌め込まれ、軒樋溝部の端部が覆材内に差し込むことができれば、適宜な場所でよく、例えば、図４に示すように、曲り継手本体の軒樋接続部の近傍で、曲り継手本体の屋外側側壁の内側の曲り継手溝部の上部近傍から曲り継手本体の内周面に沿って、曲り継手本体の屋内側側壁のほぼ中央部までに、断面形状がほぼ横Ｊ字型の帯状の覆材の短手材を曲り継手本体の屋外側側壁の内側に取り付けるようにして覆材を設けておくと、軒樋溝部の端部を覆材内に差し込むことができ、成型し易いので、好ましい。
【００１４】
又、この横Ｊ字型の帯状の覆材の内側の形状は、横Ｊ字型の帯状の覆材を曲り継手本体の屋外側側壁の内側に取り付け、軒樋溝部の端部を覆材内に差し込んだとき、軒樋溝部の端縁が横Ｊ字型の帯状の覆材の奥部の短手材に当接しなければ、適宜な形状でよく、例えば、図７の（イ）に示すように、横Ｊ字型の帯状の覆材の長手材にテーパーをつけ、奥に行くにつれて、覆材と曲り継手溝部との間を狭くして、軒樋溝部の端縁が覆材の途中で止まるようにしたり、又、図７の（ロ）に示すように、横Ｊ字型の帯状の覆材の奥部の短手材を上部が入口方向に傾斜させて、軒樋溝部の端縁の上部が傾斜した覆材の短手材の上部に当るようにしておくと、軒樋溝部の端縁が覆材の奥まで差し込まれても、雨水が上側間隙部と下側間隙部とを通り、曲り継手本体内へ流れ込むので、好ましい。
【００１５】
又、請求項２記載の覆材を、図８に示すように、幅広の帯状でできた内押え体とし、内押え体の形状を曲り継手本体の側壁と底板の形状とほぼ同じで、大きさは曲り継手本体より若干小さくして、曲り継手本体に内押え体を嵌めることができ、曲り継手本体と内押え体との間で軒樋溝部の端部を押えて挟むようにしておいてもよい。

【００２０】
又、請求項１及び請求項２記載の発明において、軒樋接続部の屋内側及び屋外側両側壁の上端に軒樋の屋内側及び屋外側耳部を上方から押えることができる押え片が曲り継手本体の内側に突出させて設けられているから、曲り継手本体の軒樋接続部に軒樋の端部を接続したとき、軒樋接続部の両押え片で軒樋の両耳部を上方から押えることができ、しっかりと曲り継手本体に軒樋の端部を取り付けることができる。
