Description

【０００１】
【発明の属する技術分野】
本発明は軒天井取付ドレンに関する。
【０００２】
【従来の技術】
従来、床取付ドレンは、実開昭５９−１５０８２１号公報に記載あるように、上側床挟持体と、下側床挟持体とからなり、上側床挟持体は、下端部の外周面に雄ネジが設けられた内側筒状体と、この内側筒状体の上端に設けられた上側鍔状体と、上端部の上に設けられた排水キャップとからなり、下側床挟持体は、上端部内周面に雌ネジが設けられた外側筒状体と、この外側筒状体の下端部に下側鍔状体と、この下側鍔状体の外周面に雄ネジとが設けられているものである。
【０００３】
この床取付ドレンは、上側床挟持体の内側筒状体を床の上方向から床の貫通孔に挿入し、下側床挟持体の外側筒状体を床の下方向から床の貫通孔に挿入し、内側筒状体の雄ネジに外側筒状体の雌ネジを螺入して、上側鍔状体と下側鍔状体とで床を挟持し、床に床取付ドレンをしっかり固定するものである。
【０００４】
【発明が解決しようとする課題】
しかし、軒天井の上側に住宅のバルコニー、ポーチ等がある場合、軒天井の下側からの貫通孔を通してバルコニー、ポーチ等の床の裏側が見えるため、この床の裏側に化粧性を持たせるために軒天井を設けることが通常行われる。
その際、床の貫通孔の真下に軒天井の貫通孔を設けて床から軒天井の貫通した床取付ドレンを設けてもよいが、バルコニー、ポーチ等の床の床取付ドレンの取付位置の真下より別の場所に、軒天井の軒天井取付ドレンの取付位置を設けたいときがある。
ところが、図３のように、軒天井はできるだけバルコニー、ポーチ等の床に近づけて取り付けられているため、バルコニー、ポーチ等の床と軒天井との間のスペースが狭くなっている。
そのため、上記の実開昭５９−１５０８２１号公報に記載の床取付ドレンと同じ構造のドレンを軒天井取付ドレンとして使用して軒天井に取り付けようとすると、軒天井の上に床があり、床と軒天井との間のスペースが狭いため、内側筒状体を上方向から手で押えることができない。
従って、外側筒状体の雌ネジを内側筒状体の雄ネジに螺入しようとしても、内側筒状体が動いて、内側筒状体の雄ネジに外側筒状体の雌ネジを螺入できず、上側鍔状体と下側鍔状体とで軒天井をしっかりと挟持できないという問題がある。
そこで、本発明の目的は、バルコニー、ポーチ等の床と軒天井との間のスペースが狭くても、軒天井に簡単にドレンを取り付けることができる軒天井取付ドレンを提供することである。
【０００５】
【課題を解決するための手段】
請求項１記載の本発明は、上側天井挟持体と、下側天井挟持体とからなる軒天井に取り付けられる軒天井取付ドレンであって、前記上側天井挟持体は、外周面に雄ネジが設けられた内側筒状体と、この内側筒状体の上端に設けられた上側鍔状体とからなり、この上側鍔状体の下面には、下方に向けて１個以上の突出片が設けられ、前記下側天井挟持体は、上端部内周面に雌ネジが設けられた外側筒状体と、この外側筒状体の上端に設けられた下側鍔状体とからなり、前記軒天井は、貫通孔と、この貫通孔の周縁部上面に形成された凹凸部とからなり、前記軒天井の貫通孔に、上側天井挟持体の内側筒状体を上方向から挿入して、内側筒状体の上側鍔状体の下面に設けられている突出片を軒天井の上面の凹部に係止させ、内側筒状体の上側鍔状体が回転しないようにして、内側筒状体の雄ネジに下側天井挟持体の外側筒状体の雌ネジを軒天井の下方向から螺入して、上側天井挟持部と下側天井挟持部とで軒天井を挟んで固着されている軒天井取付ドレンである。
【０００６】
本発明において使われる突出片は、上側鍔状体の下面から下方に向けて突出し、軒天井の周縁部上面に形成された凹部に係止するものであれば、適宜なものでよく、例えば、上側鍔状体にコ字状の切り込みを入れて、コ字状の内側部分を下方に向けて押えて、上側鍔状体の下面から下方に突出するようにしたり、予め、上側鍔状体にコ字状の切欠とコ字状の内側部分が上側鍔状体の下面から下方に突出するように成形したり、又、上側鍔状体の下面に突出片を取り付けて、軒天井の凹部に係止するようにしてもよい。上側鍔状体にコ字状の切り込みを入れたり、コ字状の切欠付けの成形にしておくと、突出片がバネ状になるので、軒天井の周縁部上面に形成された凹部に係止させないとき、突出片が軒天井の凸部で押え込まれ、コ字状の切り込まれた部分や切欠部分に突出片が入り込んで上側鍔状体が浮き上がらず、好ましい。
【０００７】
本発明の上側天井挟持体と下側天井挟持体の材質は、合成樹脂、金属と適宜なものでよいが、例えば、塩化ビニル樹脂にすると、軽量、価格、成型性の点で好ましい。
【０００８】
本発明の上側天井挟持体の雄ネジと、内側筒状体と、上側鍔状体と、上側鍔状体のコ字状の切欠と、突出片とは射出成形法で一体成形したものが、軽量、外観の点で好ましい。又、下側天井挟持体の雌ネジと、外側筒状体と、下側鍔状体とも射出成形法で一体成形すると、軽量、外観の点で好ましい。
【０００９】
本発明の軒天井の材質は、金属、合成樹脂と適宜なものでよいが、例えば、アルミニュウムにすると、軽量、価格の点で好ましい。
【００１０】
本発明において、外側筒状体の下端部に角筒状の管、又は、継手が接続される場合には、図３に示す様にすると、簡単に接続できるので、都合がよい。
即ち、外側筒状体の上端部で相対する外面に２つの突設物と、角筒状の回転リングの上端部で外側筒状体の外面の２つの突設物に対応した位置に１つの突設物とを設け、外側筒状体の２つの突設物に、回転リングの１つの突設物を嵌め込んで、外側筒状体と回転リングを取り付け、回転リングの内側面に角筒状の管、又は、継手の外側面が当接するようにする。
【００１１】
（作用）
本発明の軒天井取付ドレンを軒天井に取り付ける場合には、先ず、軒天井に貫通孔を開け、この貫通孔に、上方向から内側筒状体を挿入して、内側筒状体の上側鍔状体の下面の突出片を軒天井の上面の凹部に係止させて、内側筒状体の上側鍔状体が回転しないようにして、内側筒状体の雄ネジに軒天井の下側の外側筒状体の雌ネジを螺入して、上側天井挟持部と下側天井挟持部とで軒天井を挟んで固着する。
【００１２】
このようにすると、上側天井挟持体は、外周面に雄ネジが設けられた内側筒状体と上側鍔状体とからなり、この上側鍔状体の下面には、下方に向けて１個以上の突出片が設けられ、下側天井挟持体は、上端部内周面に雌ネジが設けられた外側筒状体と下側鍔状体とからなり、軒天井は、貫通孔の周縁部上面に形成された凹凸部とからなっているから、上側鍔状体の下面の突出片が軒天井の上面の凹部に係止して、内側筒状体の上側鍔状体が回転せずに、内側筒状体の雄ネジに軒天井の下側から外側筒状体の雌ネジを螺入することができ、上側天井挟持部と下側天井挟持部とで軒天井を挟んでしっかりと固着することができる。従って、軒天井の上に床があり、床と軒天井との間のスペースが狭くても、簡単に、軒天井取付ドレンを軒天井に取り付けることができる。
【００１３】
【発明の実施の形態】
次に、本発明の実施例を説明する。
