Description

【０００１】
【発明の属する技術分野】
本発明は、軒樋の接続に関する。
【０００２】
【従来の技術】
従来、軒樋継手を使用して軒樋を接続する方法には、主として、軒樋と軒樋継手を接着する方法が用いられている。
この方法は、接着剤で軒樋と軒樋継手とを固着するもので、例えば、特開平９−８８２６１号公報に記載のものが知られている。
特開平９−８８２６１号公報に記載の軒樋継手は、前壁の上部前壁部と下部前壁部との間に長手方向に外面から内方に凹没する排水溝が設けられ、上部前壁部を排水溝から上部に行くに従って屋内側方向に傾く傾斜面とされたもので、軒樋継手の両端部の内周面に接着剤を塗布し、軒樋の排水長溝に軒樋継手の排水溝を嵌めながら、一方の軒樋の前壁の端部と別の軒樋の前壁の端部とを接着して、軒樋同士を接続するものである。
【０００３】
【発明が解決しようとする課題】
特開平９−８８２６１号公報に記載の軒樋継手では、軒樋継手の排水溝の深さを軒樋の排水長溝の深さより浅くして、軒樋の排水長溝に軒樋継手の排水溝を嵌めたとき、排水長溝と排水溝間に隙間を作り、軒樋の前壁の上部前壁部より排水長溝に流れ込んだ雨水を排水長溝と排水溝間に隙間を通って軒樋継手内に流れ込むようにされている。
【０００４】
ところが、図３に示すように、軒樋継手Ｃの両端部の内周面に接着剤４を塗布し、軒樋の外周面に接着するとき、排水溝３３ｂの外周面に塗布された接着剤６が、軒樋の排水長溝内に付着し、溜まって、排水長溝と排水溝３３ｂ間の隙間５が塞がれ、雨水を軒樋継手内へ流すことができず、雨水が排水長溝から溢れでるという問題があった。
又、軒樋の排水長溝に軒樋継手の排水溝３３ｂを嵌めて、排水長溝と排水溝３３ｂ間に隙間を作るため、軒樋継手Ｃの排水溝３３ｂの深さを軒樋の排水長溝の深さより浅くせねばならない。そのため、軒樋継手Ｃの排水溝３３ｂは小さくなり、雨水を十分に受け止めることができず、雨水が排水溝３３ｂから溢れでるという問題があった。
【０００５】
そこで、本発明の目的は、軒樋の排水長溝が接着剤で塞がれず、雨水を軒樋継手の排水溝を通って、軒樋継手内に流すことができ、軒樋継手の排水溝を大きくして雨水を十分に受け止めることができる軒樋継手を提供するものである。
【０００６】
【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記載の発明では、前壁の上部前壁部と下部前壁部との間に外面から内方に凹没する排水長溝が長手方向にわたって設けられ、上部前壁部は屋内側に向けて傾く傾斜面とされた軒樋を接続する軒樋継手において、軒樋継手の前壁は、上部前壁部と、下部前壁部と、両前壁部との間に設けられた外面から内方に凹没する排水溝と、両前壁部を長手方向のほぼ中央部で繋ぐ繋ぎ部材とからなり、繋ぎ部材は軒樋継手の内面に設けられ、この繋ぎ部材で軒樋継手の両端部に接続される一対の軒樋間に一定間隔が開けられ、排水溝には、内方先端部に長手方向に全長にわたってスリットが設けられているものである。
【０００７】
請求項２記載の発明では、前壁の上部前壁部と下部前壁部との間に外面から内方に凹没する排水長溝が長手方向にわたって設けられ、上部前壁部は屋内側に向けて傾く傾斜面とされた軒樋を接続する軒樋継手において、前記軒樋継手の前壁は、上部前壁部と、下部前壁部と、両前壁部を長手方向のほぼ中央部で繋ぐ繋ぎ部材とからなり、繋ぎ部材は軒樋継手の内面に設けられ、繋ぎ部材の下端部に切欠孔が設けられ、この繋ぎ部材で軒樋継手の両端部に接続される一対の軒樋間に一定間隔が開けられているものである。
【０００８】
本発明の軒樋継手の材質は、軒樋継手の軒樋接続部の内周面に接着剤を塗布して、軒樋の外周面と接着できるものであれば、適宜な材質でよく、例えば、軒樋が硬質塩化ビニル樹脂である場合は、硬質塩化ビニル樹脂用の溶剤系の接着剤が使用されるので、軒樋継手の材質も硬質塩化ビニル樹脂を使用するとよい。
尚、軒樋継手の軒樋接続部に塗布する接着剤は、両端部の軒樋接続部の内周面に帯状に塗布すると、接着剤を節約できるので、好ましい。
【０００９】
請求項１記載の発明において、繋ぎ部材の形状は、前壁の上部前壁部と下部前壁部とを長手方向のほぼ中央部で繋ぐことができれば、適宜な形状でよく、例えば、図１の（ロ）に示すように、軒樋継手の内面で、２枚の板状体の小片を一定間隔あけて、小片の上端部を上部前壁部に取り付け、小片の下端部を下部前壁部に取り付けて、上部前壁部と下部前壁部とを繋ぐようにすると、一方の軒樋の端部を一方の小片まで差し込み、他方の端部を他方の小片まで差し込むことによって、一対の軒樋間に一定間隔開けることができるので、好ましい。
尚、繋ぎ部材を１枚の板状体の小片にしてもよいが、この場合は１枚の板状体の小片の左右近傍で、軒樋継手の内面にリブを突設させ、一方の軒樋の端部を一方のリブで止め、他方の軒樋の端部を他方のリブで止めて、一対の軒樋間に一定間隔を開けるようにして、この一定間隔を開けたところのスリット（後述説明）から雨水を軒樋継手内に流すようにするとよい。
【００１０】
請求項１記載の発明において、排水溝の長さは、軒樋の排水長溝から流れてきた雨水を排水溝を通して、軒樋継手内に流すことができれば、適宜な長さでよく、例えば、前壁の長手方向に全長わたって設けられてもよいし、長手方向のほぼ中央部の一部分に設けられてもよい。
排水溝の形状は、軒樋の排水長溝に嵌めることができ、排水溝を通って雨水が軒樋継手内に流すことができれば、適宜な形状でよく、例えば、排水溝の形状を円弧状にして、円弧状の先端部から下部のいずれかの位置に長手方向に全長にわたってスリットを設けるようにすると、排水溝を通って雨水を、上記の一定間隔あけられた繋ぎ部材である２枚の板状体の小片間のスリットから軒樋継手内に流すことができるので、好ましい。
【００１１】
請求項１記載の発明において、軒樋継手の前壁の上部前壁部と下部前壁部と繋ぎ部材と排水溝と、底部と、後壁とは、射出成型法で一体に成形すると、美観の点で好ましい。
【００１２】
請求項２記載の発明において、繋ぎ部材の形状は、前壁の上部前壁部と下部前壁部とを長手方向のほぼ中央部で繋ぐことができ、繋ぎ部材より雨水が軒樋継手内に流すことができれば、適宜な形状でよく、例えば、円弧状になった１枚の帯状の小片にして、小片の下部に切欠孔を設け、小片の上端部を上部前壁部に取り付け、小片の下端部を下部前壁部に取り付けて、上部前壁部と下部前壁部とを繋ぐようにすると、円弧状の小片の一方の端縁まで一方の軒樋の端部を差し込み、円弧状の小片の他方の端縁まで他方の軒樋の端部を差し込むことによって、一対の軒樋間に一定間隔を開け、繋ぎ部材の切欠孔から雨水を軒樋継手に流すことができるので、好ましい。
【００１３】
請求項２記載の発明において、軒樋継手の前壁の上部前壁部と下部前壁部と繋ぎ部材と、底部と、後壁とは、射出成型法で一体に成形すると、美観の点で好ましい。
【００１４】
（作用）
請求項１記載の軒樋継手は、前壁が上部前壁部と、下部前壁部と、これらの両前壁部との間に設けられた外面から内方に凹没する排水溝と、両前壁部を長手方向のほぼ中央部で繋ぐ繋ぎ部材とからなり、繋ぎ部材は軒樋継手の内面に設けられ、この繋ぎ部材で軒樋継手の両端部に接続される一対の軒樋間に一定間隔が開けられ、排水溝には、内方先端部に長手方向に全長にわたってスリットが設けられているから、一方の軒樋の端部の排水長溝に軒樋継手の一方の端部の排水溝を嵌め込みながら、繋ぎ部材の一方の小片まで軒樋の端部を差し込み、他方の軒樋の端部の排水長溝に軒樋継手の他方の端部の排水溝を嵌め込みながら、繋ぎ部材の他方の小片まで軒樋の端部を差し込むことによって、一対の軒樋間に一定間隔が開けることができ、この一定間隔あけられたところのスリットから排水溝を通ってきた雨水を軒樋継手内に流すことができる。
【００１５】
又、排水溝には、内方先端部に長手方向に全長にわたってスリットが設けられているから、接着剤を軒樋継手の前壁の内周面に塗布しても、このスリット部分には接着剤が付着しない。従って、排水長溝に排水溝を差し込んでも、軒樋継手の前壁の内周面に塗布された接着剤が、排水長溝の内面に付着することがなく、接着剤で軒樋の端部の排水長溝が塞がれることなく、軒樋の排水長溝を通ってきた雨水を軒樋継手内に流すことができる。
【００１６】
又、排水溝には、内方先端部に長手方向に全長にわたってスリットが設けられているから、軒樋の端部の排水長溝に軒樋継手の端部の排水溝を嵌めるとき、排水長溝と排水溝間に隙間を設けず、排水長溝の内周面に排水溝の外周面を当接させても、雨水を軒樋継手内に流すことができる。従って、排水長溝の深さに合わせて、排水溝の肉厚分だけ浅い深さの排水溝にすることができ、軒樋継手の排水溝を大きくすることができる。
【００１７】
請求項２記載の軒樋継手は、前壁が上部前壁部と、下部前壁部と、これらの両前壁部を長手方向のほぼ中央部で繋ぐ繋ぎ部材とからなり、繋ぎ部材は軒樋継手の内面に設けられ、繋ぎ部材の下端部に切欠孔が設けられ、この繋ぎ部材で軒樋継手の両端部に接続される一対の軒樋間に一定間隔が開けられているから、一方の軒樋の端部の排水長溝を繋ぎ部材の一方の端縁まで差し込み、他方の軒樋の端部の排水長溝を繋ぎ部材の他方の端縁まで差し込むことによって、一対の軒樋間に一定間隔が開けることができ、繋ぎ部材の下端部に切欠孔から雨水を軒樋継手内に流すことができる。
【００１８】
又、上部前壁部と下部前壁部とがほぼ中央部で繋ぎ部材で繋がれ、繋ぎ部材の下端部に切欠孔が設けられているから、接着剤を軒樋継手の前壁の内面に塗布しても、この上部前壁部と下部前壁部との間は開いており、上部前壁部と下部前壁部との間には接着剤が付着しない。従って、たとえ、軒樋の端部の排水長溝を軒樋継手の端部の上部前壁部と下部前壁部との間に差し込んでも、軒樋継手の前壁の内面に塗布された接着剤が、排水長溝の内面に付着するこがなく、接着剤で軒樋の端部の排水長溝を塞がれることなく、軒樋の排水長溝を通ってきた雨水を軒樋継手内に流すことができる。
【００１９】

以下，本発明の一実施例を図１に基づいて詳述する。

【００２１】
前壁３は、上部前壁部３１と、下部前壁部３２と、これらの上部前壁部３１と下部前壁部３２との間に設けられた外面から内方に凹没する排水溝３３と、これらの上部前壁部３１と下部前壁部３２とを長手方向のほぼ中央部で繋ぐ繋ぎ部材３４とからなっている。
【００２２】
上部前壁部３１は、屋内側に向けて傾く傾斜面とされ、上部前壁部３１の両端部の上端縁に屋内側に向けて引掛部３６、３６が設けられている。
下部前壁部３２は、底部２よりほぼ垂直に上方向に立設されている。
繋ぎ部材３４は、２枚の板状体の小片３５、３５からなっており、軒樋継手Ａの内面のほぼ中央部で、一定間隔を開けて、排水溝３３のスリット３７に掛け渡されて、小片３５の上端部が排水溝３３の上部に、小片３５の下端部が排水溝３３の下部に取り付けられている。
排水溝３３は、ほぼ円弧状になされ、この円弧状の斜め下方の位置の内方先端部に長手方向に全長にわたってスリット３７が設けられている。
【００２３】
次に，この軒樋継手Ａの取付方法を説明しながら、作用を説明する。
本実施例の軒樋継手Ａは、家屋の軒先先端部に取り付けられた軒樋（図示省略）を次のようにして接続する。
図１に示すように、先ず、軒樋継手Ａの両端部の軒樋接続部１の内周面に帯状に接着剤を前壁３から後壁４にかけて塗布する。
次に、軒樋の端部同士が、軒樋継手Ａのほぼ中央部の繋ぎ部材３４の小片３５、３５にくるように合わせ、後壁４の両端部の上端縁に屋内側に向けて引掛部（図示省略）を軒樋の端部の屋内側耳部（図示省略）に引っ掛ける。
【００２４】
次に、屋内側耳部を軸として軒樋継手Ａを手前に回動させる。軒樋を軒樋継手Ａの軒樋接続部１に嵌め、上部前壁部３１の両端部の上端縁に屋内側に向けて引掛部３６、３６を軒樋の端部の屋外側耳部（図示省略）に引っ掛け、軒樋継手Ａを軒樋の端部に取り付ける。
【００２５】
このようにすると、軒樋継手Ａの前壁３は、上部前壁部３１と、下部前壁部３２と、両前壁部３１、３２との間に設けられた外面から内方に凹没する円弧状の排水溝３３と、両前壁部３１、３２を長手方向のほぼ中央部で繋ぐ繋ぎ部材３４である２枚の板状体の小片３５、３５とからなり、２枚の板状体の小片３５、３５は軒樋継手Ａの内面に設けられ、この２枚の板状体の小片３５、３５で軒樋継手Ａの両端部に接続される一対の軒樋間に一定間隔が開けられ、排水溝３３には、内方先端部に長手方向に全長にわたってスリット３７が設けられているから、一方の軒樋の端部の排水長溝（図示省略）に軒樋継手Ａの一方の端部の排水溝３３を嵌め込みながら、繋ぎ部材３４の一方の小片３５まで軒樋の端部を差し込み、他方の軒樋の端部の排水長溝に軒樋継手Ａの他方の端部の排水溝３３を嵌め込みながら、繋ぎ部材３４の他方の小片３５まで軒樋の端部を差し込むことによって、一対の軒樋間に一定間隔が開けることができ、この一定間隔あけられたところのスリット３７から排水溝３３を通ってきた雨水を軒樋継手Ａ内に流すことができる。
【００２６】
又、排水溝３３には、内方先端部に長手方向に全長にわたってスリット３７が設けられているから、接着剤を軒樋継手Ａの前壁３の内周面に塗布しても、このスリット３７部分には接着剤が付着しない。従って、排水長溝に排水溝３３を差し込んでも、軒樋継手Ａの前壁３の内周面に塗布された接着剤が、排水長溝の内面に付着することがなく、接着剤で軒樋の端部の排水長溝が塞がれることなく、軒樋の排水長溝を通ってきた雨水を軒樋継手Ａ内に流すことができる。
【００２７】
排水溝３３には、内方先端部に長手方向に全長にわたってスリット３７が設けられているから、軒樋の端部の排水長溝に軒樋継手の端部の排水溝３３を嵌めるとき、排水長溝と排水溝３３間に隙間を設けず、排水長溝の内周面に排水溝３３の外周面を当接させても、雨水を軒樋継手Ａ内に流すことができる。従って、排水長溝の深さに合わせて、排水溝３３の肉厚分だけ浅い深さの排水溝３３にすることができ、軒樋継手Ａの排水溝３３を大きくすることができる。
【００２８】
次に，本発明の他の実施例を図２に基づいて詳述する。
図２の（イ）は軒樋継手の斜視説明図、（ロ）は軒樋継手の一方の端部に軒樋が嵌め込まれている状態を示す斜視説明図である。
【００２９】
図２に示す軒樋継手は、図１に示す軒樋継手の排水溝３３がなく、前壁の上部前壁部３１と下部前壁部３２とを繋ぐ繋ぎ部材３４の形状が異なるだけで、下記の構造と作用を除き、構造、取付方法と作用は殆ど同じであるので、この異なるところのみを説明し、その他の説明は省略する。
【００３０】
図２において、Ｂは軒樋継手であり、この軒樋継手Ｂの前壁３ａは、上部前壁部３１ａと、下部前壁部３２ａと、長手方向のほぼ中央部で、上部前壁部３１ａと下部前壁部３２ａとの間に設けられた繋ぎ部材３４ａとからなっている。
【００３１】
繋ぎ部材３４ａは、軒樋の排水長溝とほぼ同じ形をした円弧状になった１枚の帯状体であり、繋ぎ部材３４ａの下部に切欠孔３８が設けられている。
繋ぎ部材３４ａの上端部は上部前壁部３１ａの下端部に取り付けられ、繋ぎ部材３４ａの下端部は下部前壁部３２ａの上端部に取り付けられている。
【００３２】
次に，この軒樋継手Ａの取付方法を説明しながら、作用を説明する。
図２に示すように、軒樋の端部が、軒樋継手Ｂのほぼ中央部の繋ぎ部材３４ａの一方の端縁にくるように合わせ、他方の端縁にも他方の軒樋の端部（図示省略）がくるように合わせて、後壁４ａの両端部の上端縁に屋内側に向けて引掛部（図示省略）を軒樋の端部の屋内側耳部（図示省略）に引っ掛ける。
【００３３】
次に、屋内側耳部を軸として軒樋継手Ｂを手前に回動させる。軒樋を軒樋継手Ｂの軒樋接続部１ａに嵌め、上部前壁部３１ａの両端部の上端縁に屋内側に向けて設けられた引掛部３６ａ、３６ａを軒樋の端部の屋外側耳部（図示省略）に引っ掛け、軒樋継手Ｂを軒樋の端部に取り付ける。
【００３４】
このようにすると、軒樋継手Ｂの前壁３ａは、上部前壁部３１ａと、下部前壁部３２ａと、両前壁部３１ａ、３２ａとの間に設けられた繋ぎ部材３４ａとからなり、繋ぎ部材３４ａは軒樋継手Ｂの内面に設けられ、この繋ぎ部材３４ａで軒樋継手Ｂの両端部に接続される一対の軒樋間に一定間隔が開けられ、繋ぎ部材３４ａの下部に切欠孔３８が設けられているから、一方の軒樋の端部の排水長溝（図示省略）を繋ぎ部材３４ａの一方の端縁まで差し込み、他方の軒樋の端部の排水長溝を繋ぎ部材３４ａの他方の端縁まで差し込むことによって、一対の軒樋間に一定間隔が開けることができ、この繋ぎ部材３４ａの下部に切欠孔３８から雨水を軒樋継手Ｂ内に流すことができる。
【００３５】
又、上部前壁部３１ａと下部前壁部３２ａとがほぼ中央部で繋ぎ部材３４ａで繋がれ、繋ぎ部材３４ａの下端部に切欠孔３８が設けられているから、接着剤を軒樋継手Ｂの前壁３ａの内周面に塗布しても、この上部前壁部３１ａと下部前壁部３２ａとの間は開いており、上部前壁部３１ａと下部前壁部３２ａとの間には接着剤が付着しない。従って、たとえ、軒樋の端部の排水長溝を軒樋継手の端部の上部前壁部３１ａと下部前壁部３２ａとの間に差し込んでも、軒樋継手の前壁３ａの内周面に塗布された接着剤が、排水長溝の内面に付着するこがなく、接着剤で軒樋の端部の排水長溝を塞がれることなく、軒樋の排水長溝を通ってきた雨水を軒樋継手Ｂ内に流すことができる。
【００３６】
以上、本発明実施例を図面に基づいて説明してきたが、具体的な構成はこの実施例の限られるものではなく本発明の要旨を逸脱しない範囲の設計変更等があっても本発明に含まれる。例えば、本発明の他の実施例では、長手方向のほぼ中央部で、上部前壁部３１ａと下部前壁部３２ａとの間に繋ぎ部材３４ａが設けられ、この繋ぎ部材３４ａは、円弧状になった１枚の帯状体であるが、縦方向の断面形状が円弧状になった箱体で、箱体の屋外側側壁の下部に切欠孔と箱体の底部を開口したものでもよい。
【００３７】
【発明の効果】
以上説明してきたように、請求項１記載の軒樋継手は、前壁が、上部前壁部と、下部前壁部と、両前壁部との間に設けられた外面から内方に凹没する排水溝と、両前壁部を長手方向のほぼ中央部で繋ぐ繋ぎ部材とからなり、繋ぎ部材は軒樋継手の内面に設けられ、この繋ぎ部材で軒樋継手の両端部に接続される一対の軒樋間に一定間隔が開けられ、排水溝には、内方先端部に長手方向に全長にわたってスリットが設けられているから、一方の軒樋の端部の排水長溝に軒樋継手の一方の端部の排水溝を嵌め込みながら、繋ぎ部材の一方の小片まで軒樋の端部を差し込み、他方の軒樋の端部の排水長溝に軒樋継手の他方の端部の排水溝を嵌め込みながら、繋ぎ部材の他方の小片まで軒樋の端部を差し込むことによって、一対の軒樋間に一定間隔が開けることができ、この一定間隔あけられたところのスリットから排水溝を通ってきた雨水を軒樋継手内に流すことができる。従って、排水長溝と排水溝間の隙間が設けられていても、接着剤でこの隙間を塞ぐことなく、雨水が排水長溝から溢れでることはない。
【００３８】
又、排水溝には、内方先端部に長手方向に全長にわたってスリットが設けられているから、接着剤を軒樋継手の前壁の内周面に塗布しても、このスリット部分には接着剤が付着しない。従って、たとえ、軒樋の端部の排水長溝に軒樋継手の端部の排水溝を嵌めて、排水長溝と排水溝間に隙間を設けても、軒樋継手の前壁の内周面に塗布された接着剤が、排水長溝の内面に付着するこがなく、接着剤で軒樋の端部の排水長溝が塞がれることなく、軒樋の排水長溝を通ってきた雨水を軒樋継手内に流すことができる。
【００３９】
又、排水溝には、内方先端部に長手方向に全長にわたってスリットが設けられているから、軒樋の端部の排水長溝に軒樋継手の端部の排水溝を嵌めるとき、排水長溝と排水溝間に隙間を設けず、排水長溝の内周面に排水溝の外周面を当接させても、雨水を軒樋継手内に流すことができる。従って、排水長溝の深さに合わせて、排水溝の肉厚分だけ浅い深さの排水溝にすることができ、軒樋継手の排水溝を大きくすることができ、排水溝で雨水を十分に受け止めることができる。
【００４０】
請求項２記載の軒樋継手は、前壁が上部前壁部と、下部前壁部と、これらの両前壁部を長手方向のほぼ中央部で繋ぐ繋ぎ部材とからなり、繋ぎ部材は軒樋継手の内面に設けられ、繋ぎ部材の下端部に切欠孔が設けられ、この繋ぎ部材で軒樋継手の両端部に接続される一対の軒樋間に一定間隔が開けられているから、一方の軒樋の端部の排水長溝を繋ぎ部材の一方の端縁まで差し込み、他方の軒樋の端部の排水長溝を繋ぎ部材の他方の端縁まで差し込むことによって、一対の軒樋間に一定間隔が開けることができ、繋ぎ部材の下端部に切欠孔から雨水を軒樋継手内に流すことができる。
【００４１】
又、上部前壁部と下部前壁部とがほぼ中央部で繋ぎ部材で繋がれ、繋ぎ部材の下端部に切欠孔が設けられているから、接着剤を軒樋継手の前壁の内面に塗布しても、この上部前壁部と下部前壁部との間は開いており、上部前壁部と下部前壁部との間には接着剤が付着しない。従って、たとえ、軒樋の端部の排水長溝を軒樋継手の端部の上部前壁部と下部前壁部との間に差し込んでも、軒樋継手の前壁の内面に塗布された接着剤が、排水長溝の内面に付着するこがなく、接着剤で軒樋の端部の排水長溝を塞がれることなく、軒樋の排水長溝を通ってきた雨水を軒樋継手内に流すことができる。
