【発明の属する技術分野】
本発明は、軒樋同士を接続させる軒樋継手に関する発明である。
【０００２】
【従来の技術】
従来から、軒樋同士を接続させる軒樋継手にあっては、図１７に示すように、底壁の前端縁に前壁３を立設させると共に底壁の後端縁に後壁４を立設させて軒樋の外面に沿わせるように縦断面略Ｕ字状の継手本体１で主体が構成され、そして、上記継手本体１の長手方向の両端部に軒樋を接続させる軒樋接続部が設けられるものであった。この軒樋継手にあっては、後壁４を建物に沿わせて位置させると共に前壁３を建物と反対側である外側に位置させるようにして建物に沿わせて配置されるものである。
【０００３】
【発明が解決しようとする課題】
ここで、建物と反対側である外側に位置させた前壁３の外面には雨水が降りかかるものであるが、この雨水にあっては、前壁３の外面を伝ってそのまま流下し、つまり軒樋継手から地面に滴り落ちてしまうものであった（矢印Ｄ）。
【０００４】
本発明は上記の点に鑑みてなされたものであり、前壁の外面に降りかかった雨水を地面に滴り落とさずに継手本体内に取り込むようにした軒樋継手を提供することを課題とするものである。
【０００５】
【課題を解決するための手段】
上記課題を解決するために本発明の請求項１に係る軒樋継手は、底壁２の前端縁に前壁３を立設すると共に底壁２の後端縁に後壁４を立設して縦断面略Ｕ字状にした継手本体１で主体が構成され、上記継手本体１の長手方向の両端に軒樋接続部を設けた軒樋継手において、前壁３を底壁２と一体となった下前壁３ｂと、上記下前壁３ｂと別体の上前壁３ａとで構成し、上方に行く程後方に位置するような傾斜を持たせると共に下端部分近傍に後方且つ斜め下方に凹没部２４を凹没させて上前壁３ａを形成し、上前壁３ａを下前壁３ｂの上部に装着し、上記凹没部２４の下端で構成された上前壁３ａの下端を下前壁３ｂの上端よりも後方位置に位置させるようにして上前壁３ａの下端と下前壁３ｂの上端との間に隙間５を介在させたことを特徴とする。これにより、上前壁３ａの外面に降りかかった雨水は上前壁３ａの外面に沿って流下し、下前壁３ｂの上端と隙間５を隔てて位置した上前壁３ａの下端から水切れよく滴り落ちるものであり、このとき、上前壁３ａの下端を下前壁３ｂの上端よりも後方位置に位置しているから、上前壁３ａの下端から滴り落ちる雨水は継手本体１の内部に流れ込むものであり、しかして、上前壁３ａの外面に降りかかった雨水が軒樋継手から地面に滴り落ちるように流下するといったことを無くすることができるものである。
【０００６】
また、本発明の請求項２に係る軒樋継手は、請求項１において、上前壁３ａの下端から係合突起６を下方に突設すると共に、下前壁３ｂの上端に係合孔７を上下方向に穿設し、上記係合突起６を係合孔７に嵌め合わせて上前壁３ａと下前壁３ｂとを装着したことを特徴とする。これにより、上前壁３ａを下前壁３ｂに装着するにあたり、上前壁３ａの係合突起６を下前壁３ｂの係合孔７に上方から挿入することで下前壁３ｂに対して上前壁３ａが位置決めされて装着することができ、しかして、位置ずれを無くして上前壁３ａと下前壁３ｂとを装着することができることから施工性が向上するものである。
【０００７】
また、本発明の請求項３に係る軒樋継手は、請求項１において、建物の角部に沿わせて配置される上面視略Ｌ字状の軒樋継手であって、上前壁３ａの下端から係止突起８を下方に突設すると共に下前壁３ｂの上端から係止片９を後方に突設し、上記係止突起８を係止片９に引掛け係止させて継手本体１の長手方向の両端近傍にあたる上前壁３ａと下前壁３ｂとを装着し、上前壁３ａの下端から係合突起６を下方に突設すると共に下前壁３ｂの上端に上下方向に係合孔７を穿設し、上記係合突起６を係合孔７に嵌め合わせて建物の角部に位置する前壁３の屈曲部分にあたる上前壁３ａと下前壁３ｂとを装着したことを特徴とする。これにより、上面視略Ｌ字状の軒樋継手における上前壁３ａと下前壁３ｂとの装着は、継手本体１の長手方向の両端近傍部分と前壁３の屈曲部分といった複数箇所で行われるものであり、上前壁３ａと下前壁３ｂとの装着がブレなく強固に行われるものである。
【０００８】
また、本発明の請求項４に係る軒樋継手は、請求項１において、継手本体１の内面に沿わせた軒樋２５の長手方向の端部が差し込まれる差込隙間を継手本体１の長手方向の端部に開口するように形成して軒樋接続部を構成し、上前壁３ａの上端には継手本体１に接続した軒樋２５の軒樋前壁２７に係止する耳係止爪１４を設けたことを特徴とする。これにより、継手本体１の長手方向の端部に開口するように形成した差込隙間に継手本体１の前壁３内面に沿わせた軒樋２５を差し込むことで施工性よく軒樋継手を軒樋２５に接続支持させることができ、また、上前壁３ａの上端に設けた耳係止爪１４を軒樋前壁２７の上端に引掛け係止することで上前壁３ａを軒樋２５からも支持させることができ、上前壁３ａの下前壁３ｂへの装着強度を向上させることができるものである。
【０００９】
【発明の実施の形態】
以下、本発明を添付図面に示す実施形態に基づいて説明する。
【００１０】
図１乃至図１６に本発明の実施の形態の例を示す。本例の軒樋継手は建物の出隅に沿って配置される外曲がりの軒樋継手である。この軒樋継手にあっては、軒樋２５を接続させる軒樋接続部を長手方向の両端に備えた継手本体１で主体が構成されている。この継手本体１は、内面に軒樋２５を沿わすために軒樋２５より一廻り大きく且つ軒樋２５と略同様の断面形状である縦断面略Ｕ字状にするように底壁２の前端縁に前壁３を立設すると共に底壁２の後端縁に後壁４を立設して形成したものである。ここで、上記継手本体１の前壁３にあっては別体である上前壁３ａ及び下前壁３ｂの２部材により構成されている。具体的に、継手本体１は、底壁２と後壁４と下前壁３ｂとで縦断面略Ｕ字状に形成した本体部材２０（図２乃至図５）と、上記本体部材２０の下前壁３ｂの上部に装着される上前壁３ａである板状のカバー部材２１（図６乃至図９）とで構成されているものである。なお、カバー部材２１は、その上端が本体部材２０の後壁４よりも上方位置まで至るように配置されるもので、建物の屋根に沿って流下する雨水が上記屋根の下端から飛び出した際にも上記雨水をカバー部材２１の内面に当て、後述する本体部材２０の排水溝に流し込むといった役割を担うものである。
【００１１】
本体部材２０は、図２及び図３に示すように、底壁２の前端縁に上前壁３ａを立設すると共に底壁２の後端縁に後壁４を立設して縦断面略Ｕ字状で且つ上面視略Ｌ字状に形成したものである。ここで、上記底壁２と後壁４と下前壁３ｂとで凹状に囲まれる部位は軒樋の排水が流れる排水溝を構成している。本例の軒樋継手は建物の出隅に配置される外曲がりの軒樋継手であるから、本体部材２０は、建物に沿う後壁４の外面が対向するように（建物の正面側に位置する下前壁３ｂの内面が対向するように）屈曲しているものである。
【００１２】
そして、この本体部材２０の長手方向の両端部にはそれぞれ軒樋接続部が設けられるものである。ここで、この軒樋継手に接続される軒樋２５は、軒樋底壁２６と軒樋前壁２７と軒樋後壁２８とで縦断面略Ｕ字状に主体が構成されると共に、軒樋前壁２７及び軒樋後壁２８の上端にそれぞれ耳部を設け、上記軒樋前壁２７の上下中央部分に後方に向って凹没した凹溝部２９を略水平方向に亙るように形成したものである。この軒樋接続部はカバー部材２１と本体部材２０とに亙って設けられるものであるが、本体部材２０にあっては、本体部材２０の内面に積層した軒樋２５の軒樋前壁２７及び軒樋底壁２６の前半分を挟持する前挟持部１０と、上記軒樋２５の軒樋後壁２８及び軒樋底壁２６の後半分を挟持する後挟持部１１と、上記軒樋２５の軒樋後壁２８の耳部（以下、後耳部２８ａ）を嵌合する後耳嵌合部１２とが設けられている。これらは、それぞれ本体部材２０の内面に沿わせた軒樋２５の長手方向の端部が差し込まれる差込隙間を本体部材２０の長手方向の端部に開口するように形成されている。具体的には、前挟持部１０は本体部材２０の底壁２及び下前壁３ｂから突設されて底壁２及び下前壁３との間に一定の隙間１０ａを形成する板片で構成されており、また、後挟持部１１は本体部材２０の底壁２及び後壁４から突設されて底壁２及び後壁４との間に一定の隙間１１ａを形成する板片で構成されている。なお、後挟持部１１を構成する板片のうち後壁４に平行にした部分には前方に突出した半リング１９が設けられている。この半リング１９は後述する針金取付片１８に一端を結わい付けた銅線等の金属線の他端を結わい付けて、軒樋継手の強度を向上させるためのものである。また、後耳嵌合部１２は本体部材２０の後壁４の上端に設けた軒樋２５の後耳部２８ａを挿入する隙間１２ａを形成するような断面Ｌ字状の板片で構成されている。なお、この後耳嵌合部１２は、軒樋２５の後耳部２８ａを上記隙間１２ａに挿入し易くさせるように、継手本体１の長手方向の端部に行く程隙間１２ａを大きくするような形状にしてある。つまり、本体部材２０では上記差込隙間は隙間１０ａ，１１ａ，１２ａで構成されている。
【００１３】
また、本体部材２０の下前壁３ｂは上方に行く程前方に位置するような傾斜を有して立設しているものであるが、その上端部分にはカバー部材２１を位置決めして取り付ける嵌合取付部２２と、カバー部材２１を単に係止させて取り付ける係止取付部２３とが設けられている。この嵌合取付部２２は下前壁３ｂの本体部材２０の屈曲部分に設けられ、係止取付部２３は下前壁３ｂの本体部材２０の長手方向の両端部近傍に設けられている。具体的に、嵌合取付部２２は、図４に示すように、下前壁３ｂから一定の隙間を隔てた内方位置で下前壁３ｂに平行配置した上面視略Ｌ字状の板状の取付片２２ａと、下前壁３ｂの上端のうち屈曲頂点部分から略水平後方に突出して取付片２２ａの中央に連結する中央リブ２２ｂと、下前壁３ｂの上端のうち屈曲頂点部分から長手方向の両方に一定間隔を隔てた位置からそれぞれ略水平後方に突出して取付片２２ａの長手方向端部に連結する１対の側端リブ２２ｃとで構成されるものである。ここで、中央リブ２２ｂと１対の側端リブ２２ｃと取付片２２ａの間には上下隙間である１対の係合孔７が上面視Ｌ字状に直交するように形成されている。また、取付片２２ａは上方にいく程後方に位置するような傾斜を有しており、上記係合孔７は下方に行く程狭い隙間になるように形成されている。また、係止取付部２３は、図５に示すように、下前壁３ｂの上端内面から後方且つ斜め上方に突出した長手方向に長く形成した板状の係止片９で構成される。ここで、上記係止片９の長手方向の中央部分には係止片９を切り欠いて水平方向に折り曲げた爪受片９ａが形成されると共に、下前壁３ｂの上端内面と係止片９とを連結した補強リブ２３ａが設けられている。
【００１４】
一方、カバー部材２１は、図６及び図７に示すように、上方に行く程後方に位置する傾斜を有すると共に上面視略Ｌ字状に形成した板状部材である。なお、上記傾斜はその内面が軒樋継手に接続される軒樋２５の軒樋前壁２７の外面に沿うように形成されている。このカバー部材２１の長手方向の両端部にはそれぞれ軒樋接続部が設けられている。上述したように軒樋接続部はカバー部材２１と本体部材２０とに亙って設けられるものであるが、カバー部材２１にあっては、継手本体１の内面に積層した軒樋２５の軒樋前壁２７の耳部（以下、前耳部２７ａ）を係止する前耳嵌合部１３が設けられている。具体的には、この前耳嵌合部１３はカバー部材２１の上端から後方且つ斜め下方に向けて突出すると共に突出先端から前方且つ斜め下方に向けて突出した耳係止爪１４を有した板片で構成されている。なお、前耳嵌合部１３は耳係止爪１４とカバー部材２１の内面との間に隙間１３ａを形成させている。この隙間１３ａはカバー部材２１側の差込隙間であり、カバー部材２０側の差込隙間（隙間１０ａ、１１ａ，１２ａ）と同様に継手本体１の長手方向の端部に開口させるように形成されている。また、前耳嵌合部１３の突出先端には後方且つ水平方向に突設した針金取付片１８が突設されている。この針金取付片１８は、建物や前述した半リング１９に一端を結わい付けた銅線等の金属線の他端を結わい付けて、軒樋継手の強度を向上させるためのものである。
【００１５】
このカバー部材２１は、詳述すると、その下端部分近傍では後方且つ斜め下方に凹没した凹没部２４が形成してあり、この凹没部２４の下端がカバー部材２１の下端を構成している。このカバー部材２１の下端には、本体部材２０の嵌合取付部２２の１対の係合孔７に挿入して係合させる１対の係合突起６と、本体部材２０の２つの係止取付部２３の係止片９に係止させる２つの係止突起８とが設けられている。この係合突起６はカバー部材２１の屈曲頂点部分に上面視Ｌ字状に直交するように１対設けられており、係止突起８はカバー部材２１の長手方向の両端部近傍にそれぞれ設けられている。具体的に、係合突起６は、図８に示すように、カバー部材２１の下端から下方に突出してその突出先端である下端に後方に突出した係合爪１５を備えて構成された第１係合突起６ａと、上記第１係合突起６ａの付根から前方に突出すると共にその突出先端で下方に屈曲した第２係合突起６ｂとで構成されている。ここで、第２係合突起６ｂは下方に行く程先細になる形状になっている。なお、係合突起６の幅寸法は本体部材２０の係合孔７の幅寸法と略同幅寸法に形成されている。また、係止突起８は、図９に示すように、カバー部材２１の下端から前後方向に突設された板状部材であり、この板状部材は前方を上方に位置させると共に後方を下方に位置させるような傾斜を有して設けられている。なお、係止突起８のうちカバー部材２１の下端より前方部分は係止爪１６を構成し、また、係止突起８のうちカバー部材２１の下端より後方部分はガイド１７を構成する。ここで、係合突起６は係止突起８に比べて下方突出量が大きく、その係合突起６の下端は係止突起８の下端の位置に比べて下方位置に位置しているものである。
【００１６】
上述した継手本体１を構成する本体部材２０とカバー部材２１とは、以下のように、軒樋２５を接続しながら装着される。なお、前提として軒樋２５は建物に固定した支持具等で支持されるものであって、軒樋継手は上記建物に支持された軒樋２５によって支持されるものである。
【００１７】
まず、図１０及び図１１に示すように、継手本体１の軒樋接続部（前挟持部１０，後挟持部１１，後耳嵌合部１２）の差込隙間（隙間１０ａ，１１ａ，１２ａ）に軒樋２５の長手方向の端部を差し込み、軒樋２５に本体部材２０を支持させる。このとき、後耳嵌合部１２の隙間１２ａは継手本体１の長手方向の端部に行く程大きくなっているので、軒樋２５はスムーズに軒樋接続部に差し込まれる。
【００１８】
次に、図１２に示すように、軒樋２５が接続された本体部材２０にカバー部材２１を上方から被せるようにして装着する。具体的には、まず、カバー部材２１の係合突起６を本体部材２０の嵌合取付部２２の係合孔７に上方から挿入して係合固定させ、次いで、カバー部材２１の係止突起８を本体部材２０の係止取付部２３の係止片９に引掛けて係止固定させることで本体部材２０へのカバー部材２１の装着が行われる。以下、係合突起６の係合孔７への係合及び係止突起８の係止片９への係止につき詳述する。
【００１９】
係合突起６の係合孔７への係合は、図１３に示すように、第１係合突起６ａ及び第２係合突起６ｂを係合孔７に挿入し、第１係合突起６ａの係合爪１５を嵌合取付部２２を構成する取付片２２ａの下端に係止させることで行われる。このとき、第２係合突起６ｂは下方に先細りの形状になっていると共に係合孔７は上方程広い隙間を有した形状であるから、係合突起６の係合孔７への挿入はスムーズに行われるものである。また、係合突起６を係合孔７に係合固定した状態では、第１係合突起６ａの根元部分が取付片２２ａに下方に向けて弾接されると共に第１係合突起６ａの下端の係合爪１５が取付片２２ａの下端に係止されるものであり、そして、第１係合突起６ａが下端近傍で取付片２２ａに後方に向けて弾接されると共に第２係合突起６ｂが下前壁３ｂの内面に前方に向けて弾接されている。更には係合突起６の幅寸法は係合孔７の幅寸法と略同幅寸法であるから、係合突起６は係合孔７に隙間無く嵌合するのである。このように、係合突起６を係合孔７に挿入するといった簡単な動作で係合突起６の係合爪１５を取付片２２ａの下端に係止させることができ、このとき、係合突起６は係合孔７に隙間無く嵌合するので上下左右にガタつきなく係合突起６が係合孔７に係合されるものであり、カバー部材２１が本体部材２０に位置決めされて装着されるのである。
【００２０】
係止突起８の係止片９への係止は、図１４に示すように、係止突起８を係止片９に近接させていき、係止突起８の係止爪１６を係止片９の爪受片９ａに下方から引掛け係止させることで行われる。なお、係止突起８を係止片９に近接させた際に、たとえ係止突起８の下面が係止片９の爪受片９ａに当接してしまった場合でも、そのままカバー部材２１を後方に押し込むことで、係止突起８のガイド１７によりスムーズに係止突起８の係止爪１６を係止片９の爪受片９ａに導くことができ、係止突起８の係止爪１６をスムーズに係止片９の爪受片９ａに引掛け係止させることができるのである。
【００２１】
上述したカバー部材２１の本体部材２０への装着は、まず、係合突起６を係止孔に係合させて位置決め固定し、次いで、係止突起８を係止片９に係止させることで行われる。すなわち、係合突起６は係止突起８よりも下方に大きく突出することから、係合突起６を係合孔７に挿入しただけでは係止突起８の係止片９への係止は行われないからである。はじめに係合突起６の係合孔７への係合を行わせることは、この係合突起６の係合孔７への係合によってカバー部材２１の本体部材２０への位置決めを行わせるためであり、つまり、次いで行う係止突起８の係止片９への係止施工が新たに位置決めをすることなしに行わせることが図られているのである。更に言うと、はじめに行う係合突起６の係合孔７への嵌め合わせは前壁３の屈曲部分において行われるものであり、この前壁３の屈曲部分は上面視略Ｌ字状の軒樋継手のうち目立つ部分で目印となる部分であるから、上前壁３ａの下前壁３ｂへの位置合わせが容易で、係合突起６の係合孔７への嵌め合わせの良好な施工性が図られているものである。このように、本例のカバー部材２１の本体部材２０への装着は、本体部材２０とカバー部材２１とを位置決めして取り付ける係合突起６の係合孔７への係合を１箇所で行わせ、本体部材２０とカバー部材２１と単に取り付ける係止突起８の係止片９への係止を２箇所で行わせているので、係合突起６の係合孔７への嵌め合わせの際の位置決めだけで行えるワンタッチ取付動作で行われるものであり、施工性よくカバー部材２１の本体部材２０への装着が行われるのである。
【００２２】
そして、上述したように本体部材２０に装着したカバー部材２１にあっては、図１５及び１６に示すように、カバー部材２１の軒樋接続部である前耳嵌合部１３が軒樋２５の前耳部２７ａの外面に沿うと共に耳係止爪１４を前耳部２７ａに引掛け係止し、また、カバー部材２１の凹没部２４が軒樋２５の凹溝部２９の上面２９ａの外面に沿うように係止し、すなわち、カバー部材２１の前耳嵌合部１３と凹没部２４とが軒樋２５の軒樋前壁２７を上下に挟持するようにしているのである。このように、カバー部材２１は、その下端において上述した係合突起６の係合孔７への係合及び係止突起８の係止片９への係止によって本体部材２０と固定され、そして、その長手方向の端部において前耳嵌合部１３及び凹没部２４による軒樋２５の挟持によって軒樋２５と固定されるものであり、つまり、カバー部材２１は強固且つガタつきなく本体部材２０及び軒樋２５に固定支持されるものである。
【００２３】
ここで、本体部材２０にカバー部材２１を装着した状態にあっては、図１に示すように、上前壁３ａであるカバー部材２１の下端を本体部材２０の下前壁３ｂの上端よりも後方位置に位置させるようにして上前壁３ａの下端と下前壁３ｂの上端との間に隙間５を介在させてある。上前壁３ａであるカバー部材２１にあっては、建物に沿わせて軒樋継手を配置した際には建物と反対側である外側に位置されることからカバー部材２１の外面には雨水が降りかかるものである。そして、カバー部材２１の外面に降りかかった雨水はカバー部材２１の外面に沿って流下し（矢印Ａ）、本体部材２０の下前壁３ｂの上端と隙間５を隔てたカバー部材２１の下端から水切れよく滴り落ちるものである（矢印Ｂ）。このとき、カバー部材２１の下端は本体部材２０の下前壁３ｂの上端よりも後方位置に位置しているから、カバー部材２１の下端から滴り落ちる雨水は軒樋継手の内部（つまり本体部材２０の排水溝）に漏れなく流れるものである（矢印Ｃ）。しかして、カバー部材２１の外面に降りかかった雨水が軒樋継手から地面に滴り落ちることはないのである。なお、上述したが、カバー部材２１は、建物の屋根を伝って流下する雨水が屋根の下端から飛び出た際に、上記雨水をカバー部材２１の内面に当てて軒樋継手の内部に流し込むといった本来的な役割を有するものであるが、本例のカバー部材２１はその下端に凹没部２４を有すると共にカバー部材２１の下端を本体部材２０の下前壁３ｂの上端よりも後方位置に位置させていることから、カバー部材２１の内面を流下する雨水は凹没部２４で流れる勢いを弱められてカバー部材２１の下端から滴り落ちるものであり、上記カバー部材２１の外面を流下する雨水同様に軒樋継手の内部に漏れなく流れるものである。また、更に言うと、本例の軒樋継手にあっては、本体部材２０の下前壁３ｂが下端に行く程後方に位置する傾斜を有して形成されているから、上方から降る雨水は下前壁３ｂの外面には降りかかりにくいものであり、軒樋継手から流下してしまう雨水を極力少なくした構造になっているものでもある。
【００２４】
【発明の効果】
上記のように本発明の請求項１記載の軒樋継手にあっては、叙述したように、底壁と一体となった下前壁と、上記下前壁とは別体の上前壁とで構成し、上方に行く程後方に位置するような傾斜を持たせると共に下端部分近傍に後方且つ斜め下方に凹没部を凹没させて上前壁を形成し、上前壁を下前壁の上部に装着し、上記凹没部の下端で構成された上前壁の下端を下前壁の上端よりも後方位置に位置させるようにして上前壁の下端と下前壁の上端との間に隙間を介在させたので、上方に行く程後方に位置するように傾斜した上前壁の外面に降りかかった雨水は上前壁の外面に沿って流下し、下前壁の上端と隙間を隔てて位置した上前壁の下端から水切れよく滴り落ちるものであり、このとき、上前壁の下端は下前壁の上端よりも後方位置に位置しているから、上前壁の下端から滴り落ちる雨水は継手本体の内部に流れ込ませることができ、しかして、上前壁の外面に降りかかった雨水が軒樋継手から地面に滴り落ちることを無くすることができるものである。
【００２５】
また、請求項２記載の軒樋継手にあっては、請求項１の効果に加えて、上前壁の下端から係合突起を下方に突設すると共に、下前壁の上端に係合孔を上下方向に穿設し、上記係合突起を係合孔に嵌め合わせて上前壁と下前壁とを装着したので、上前壁を下前壁に装着するにあたり、上前壁の係合突起を下前壁の係合孔に上方から挿入することで下前壁に対して上前壁が位置決めされて装着することができ、しかして、位置ずれを無くして上前壁と下前壁とを装着することができることから施工性が向上するものである。
【００２６】
また、請求項３記載の軒樋継手にあっては、請求項１の効果に加えて、建物の角部に沿わせて配置される上面視略Ｌ字状の軒樋継手であって、上前壁の下端から係止突起を下方に突設すると共に下前壁の上端から係止片を後方に突設し、上記係止突起を係止片に引掛け係止させて継手本体の長手方向の両端近傍にあたる上前壁と下前壁とを装着し、上前壁の下端から係合突起を下方に突設すると共に下前壁の上端に上下方向に係合孔を穿設し、上記係合突起を係合孔に嵌め合わせて建物の角部に位置する前壁の屈曲部分にあたる上前壁と下前壁とを装着したので、上面視略Ｌ字状の軒樋継手における上前壁と下前壁との装着は、継手本体１の長手方向の両端近傍部分と前壁の屈曲部分といった複数箇所で行われるものであり、上前壁と下前壁との装着がブレなく強固に行われるものである。
【００２７】
また、請求項４記載の軒樋継手にあっては、請求項１の効果に加えて、継手本体の内面に沿わせた軒樋の長手方向の端部が差し込まれる差込隙間を継手本体の長手方向の端部に開口するように形成して軒樋接続部を構成し、上前壁の上端には継手本体に接続した軒樋の軒樋前壁に係止する耳係止爪を設けたので、継手本体の長手方向の端部に開口するように形成した差込隙間に継手本体の前壁内面に沿わせた軒樋を差し込むことで施工性よく軒樋継手を軒樋に接続支持させることができ、また、上前壁の上端に設けた耳係止爪を軒樋前壁の上端に引掛け係止することで上前壁を軒樋からも支持させることができ、上前壁の下前壁への装着強度を向上させることができるものである。

The end of the eaves bowl 25 in the longitudinal direction is inserted, and the main body member 20 is supported by the eaves bowl 25. At this time, since the gap 12a of the rear ear fitting portion 12 becomes larger toward the end portion in the longitudinal direction of the joint body 1, the eaves rod 25 is smoothly inserted into the eaves connection portion.
[0018]
Next, as shown in FIG. 12, the cover member 21 is attached to the main body member 20 to which the eaves 25 is connected from above. Specifically, first, the engagement protrusion 6 of the cover member 21 is inserted into the engagement hole 7 of the fitting attachment portion 22 of the main body member 20 from above to be engaged and fixed, and then the engagement protrusion of the cover member 21 is engaged. The cover member 21 is attached to the main body member 20 by hooking 8 to the locking piece 9 of the locking mounting portion 23 of the main body member 20 to be locked. Hereinafter, the engagement of the engagement protrusion 6 with the engagement hole 7 and the engagement of the engagement protrusion 8 with the engagement piece 9 will be described in detail.
[0019]
As shown in FIG. 13, the engagement protrusion 6 is engaged with the engagement hole 7 by inserting the first engagement protrusion 6a and the second engagement protrusion 6b into the engagement hole 7, and then the first engagement protrusion 6a. The engagement claw 15 is engaged with the lower end of the attachment piece 22a constituting the fitting attachment portion 22. At this time, the second engagement protrusion 6b is tapered downward and the engagement hole 7 has a wider gap upward, so that the engagement protrusion 6 can be inserted into the engagement hole 7. It is done smoothly. Further, in a state where the engagement protrusion 6 is engaged and fixed in the engagement hole 7, the root portion of the first engagement protrusion 6a is elastically contacted downward with the attachment piece 22a and the lower end of the first engagement protrusion 6a. The engaging claw 15 is locked to the lower end of the mounting piece 22a, and the first engaging projection 6a is elastically contacted rearward to the mounting piece 22a in the vicinity of the lower end and the second engaging projection. 6b is elastically contacted to the inner surface of the lower front wall 3b. Furthermore, since the width dimension of the engagement protrusion 6 is substantially the same as the width dimension of the engagement hole 7, the engagement protrusion 6 fits into the engagement hole 7 without a gap. Thus, the engaging claw 15 of the engaging protrusion 6 can be locked to the lower end of the mounting piece 22a by a simple operation of inserting the engaging protrusion 6 into the engaging hole 7, and at this time, 6 is engaged with the engagement hole 7 without a gap, so that the engagement protrusion 6 is engaged with the engagement hole 7 without rattling in the vertical and horizontal directions, and the cover member 21 is positioned and attached to the main body member 20. It is.

The hook 9 can be smoothly hooked and locked to the claw receiving piece 9 a of the locking piece 9.
[0021]
The cover member 21 is mounted on the main body member 20 by first engaging and engaging the engaging protrusion 6 with the engaging hole, and then engaging the engaging protrusion 8 with the engaging piece 9. Done. That is, since the engaging protrusion 6 protrudes greatly below the locking protrusion 8, the locking protrusion 8 can be locked to the locking piece 9 simply by inserting the engaging protrusion 6 into the engaging hole 7. Because it is not broken. First, the engagement protrusion 6 is engaged with the engagement hole 7 in order to position the cover member 21 on the main body member 20 by the engagement of the engagement protrusion 6 with the engagement hole 7. That is, that is, it is intended that the next locking operation of the locking projection 8 to the locking piece 9 is performed without newly positioning. More specifically, the fitting of the engaging protrusion 6 to the engaging hole 7 performed first is performed at the bent portion of the front wall 3, and the bent portion of the front wall 3 has a substantially L-shaped eaves when viewed from above. Since the conspicuous portion of the joint is a mark, it is easy to align the upper front wall 3a with the lower front wall 3b, and the workability of fitting the engagement protrusion 6 to the engagement hole 7 is good. It is what is being illustrated. As described above, when the cover member 21 of this example is mounted on the main body member 20, the engagement protrusion 6 of the engagement protrusion 6 that positions and attaches the main body member 20 and the cover member 21 is engaged at one place. In addition, since the main body member 20 and the cover member 21 are simply engaged with the engaging protrusion 9 to be attached to the engaging piece 9 at two locations, the engaging protrusion 6 is fitted into the engaging hole 7. The cover member 21 is mounted on the main body member 20 with good workability.
[0022]
And in the cover member 21 attached to the main body member 20 as described above, as shown in FIGS. 15 and 16, the front ear fitting portion 13 which is the eaves connection portion of the cover member 21 is the eaves 25. Along the outer surface of the front ear portion 27a, the ear locking claw 14 is hooked and locked to the front ear portion 27a, and the recessed portion 24 of the cover member 21 is placed on the outer surface of the upper surface 29a of the recessed groove portion 29 of the eaves bowl 25. In other words, the front ear fitting portion 13 and the recessed portion 24 of the cover member 21 sandwich the eave ridge front wall 27 of the eave ridge 25 up and down. Thus, the cover member 21 is fixed to the main body member 20 by the engagement of the engagement protrusion 6 with the engagement hole 7 and the engagement of the engagement protrusion 8 with the engagement piece 9 at the lower end thereof, and The eaves hook 25 is clamped by the front ear fitting part 13 and the recessed part 24 at the end in the longitudinal direction thereof, that is, the cover member 21 is a main body member that is strong and has no play. 20 and the eaves 25 are fixedly supported.
[0023]
Here, when the cover member 21 is attached to the main body member 20, as shown in FIG. 1, the lower end of the cover member 21, which is the upper front wall 3a, is positioned higher than the upper end of the lower front wall 3b of the main body member 20. A gap 5 is interposed between the lower end of the upper front wall 3a and the upper end of the lower front wall 3b so as to be located at the rear position. In the cover member 21 which is the upper front wall 3a, when the eaves joint is arranged along the building, it is located on the outer side opposite to the building, so rainwater is formed on the outer surface of the cover member 21. It is something that falls. Then, the rain water that has fallen on the outer surface of the cover member 21 flows along the outer surface of the cover member 21 (arrow A), and from the lower end of the cover member 21 that separates the gap 5 from the upper end of the lower front wall 3b of the main body member 20. Water is dripping well (arrow B). At this time, since the lower end of the cover member 21 is located behind the upper end of the lower front wall 3b of the main body member 20, the rainwater dripping from the lower end of the cover member 21 is inside the eaves joint (that is, the main body member 20). In the drainage groove) (arrow C). Therefore, the rain water that has fallen on the outer surface of the cover member 21 does not drip from the eaves joint to the ground. Although the cover member 21 has been described above, the rainwater flowing down along the roof of the building jumps out from the lower end of the roof, so that the rainwater hits the inner surface of the cover member 21 and flows into the eaves joint. Although the cover member 21 of this example has a recessed portion 24 at the lower end thereof, the lower end of the cover member 21 is positioned behind the upper end of the lower front wall 3b of the main body member 20. Therefore, the rainwater flowing down the inner surface of the cover member 21 is dampened from the lower end of the cover member 21 due to weakened momentum flowing in the recessed portion 24, and is similar to the rainwater flowing down the outer surface of the cover member 21. It flows without leakage into the eaves joint. In addition, in the eaves joint of this example, since the lower front wall 3b of the main body member 20 is formed to have an inclination that is located rearward as it goes to the lower end, rainwater falling from above is The outer surface of the lower front wall 3b is less likely to fall, and has a structure in which the amount of rainwater that flows down from the eaves joint is reduced as much as possible.
