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。
図1及び図2は本発明の軒天井取付ドレンの一実施例を示すもので、図1の(イ)は軒天井取付ドレンの上側天井挟持部と下側天井挟持部とに分解して示す断面説明図、(ロ)は軒天井に軒天井取付ドレンを取り付け上方向から見た状態図、(ハ)は(ロ)のX−X線矢視図、図2はバルコニー、ポーチ等の床の下に軒天井を設け、軒天井取付ドレンを軒天井に取り付けた状態を示す断面説明図である。
【0014】
図1において、Aは軒天井取付ドレンであり、この軒天井取付ドレンAは塩化ビニル樹脂製で、上側天井挟持体1と、下側天井挟持体2とからなっている。
上側天井挟持体1は、外周面に雄ネジ15が設けられた内側筒状体12と、この内側筒状体12の上端に設けられた上側鍔状体11とからなっており、この上側鍔状体11には、図1の(ハ)に示すように、左右対称の位置にそれぞれ1個づつ、同方向にむけてコ字状の切欠13と、コ字状の内側部分が上側鍔状体11の下面から下方に突出した突出片14が設けられ、この突出片14はバネ状になり、上下に動くようになされている。
【0015】
下側天井挟持体2は、上端部内周面に雌ネジ23が設けられた外側筒状体22と、この外側筒状体22の上端に設けられた下側鍔状体21とからなっている。
【0016】
軒天井3は、アルミニュウム製で、軒天井3の全体が凹凸状に形成され、軒天井3の所定の位置に貫通孔31が開けられている。
【0017】
下側天井挟持体2が軒天井3の下側に当接され、上側天井挟持体1の内側筒状体12が軒天井3の上方向から貫通孔31に挿入され、内側筒状体12の雄ネジ15が下側天井挟持体2の外側筒状体22の雌ネジ23に螺入されて、上側鍔状体11と下側鍔状体21とで軒天井3が挟持されると同時に上側天井挟持体1の上側鍔状体11の下面の突出片14が軒天井3の上面の凹部に係止されている。
【0018】
次に、この軒天井取付ドレンAの施工方法および作用について説明する。
先ず、図2に示すように、バルコニー、ポーチ等の床の排水口より接続される軒天井3の排水口の位置を決める。次に、この位置に貫通孔31を穿設する。次に、この貫通孔31に、上方向から内側筒状体12を挿入して、内側筒状体12の上側鍔状体11の下面の突出片14を軒天井3の上面の凹部に係止させる。次に、軒天井3の上面の凹部に突出片14が係止し、上側天井挟持体1の内側筒状体12の上側鍔状体11が回転しないようになされている内側筒状体12の雄ネジ15に下側天井挟持体2の外側筒状体22の雌ネジ23を螺入する。すると、上側天井挟持部1と下側天井挟持部2とで軒天井3を挟んで、軒天井取付ドレンAを軒天井3に固着する。
【0019】
このようにすると、上側鍔状体11の突出片14が軒天井3の上面の凹部に係止して、内側筒状体12の上側鍔状体11が回転せずに、内側筒状体12の雄ネジ15に軒天井3の下側から外側筒状体22の雌ネジ23を螺入することができ、上側天井挟持部1と下側天井挟持部2とで軒天井3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3の上に床4があり、床4と軒天井3との間のスペースが狭くても、簡単に、軒天井取付ドレンAを軒天井3に取り付けることができる。
【0020】
又、この上側鍔状体11には、左右対称の位置にそれぞれ1個づつ、コ字状の切欠13の内側部分が上側鍔状体11の下面から下方に突出した突出片14が設けられ、この突出片14はバネ状になっているから、軒天井3の凹部に突出片14を係止させないとき、突出片14が軒天井3の凸部で押え込まれ、コ字状の切欠13に突出片14が入り込んで上側鍔状体11が浮き上がるようなことはなく、上側鍔状体11の下面は軒天井3の凸部に当接し、しっかりと収まっている。
【0021】
次に、他の実施例を図3に基づいて説明する。
図3の(イ)は外側筒状体の外面に角筒状の回転リングが取り付けた断面説明図、(ロ)は(イ)のY−Y線矢視図である。

本実施例では、一実施例の外側筒状体の下端部への接続が円筒状の管、又は、継手でなく、角筒状の管、又は、継手を接続するようになっているところが異なるだけで、下記の構造と作用を除き、構造、使用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。
【0023】
図3において、外側筒状体22aの上端部で相対する外面に2つの突設物24、24と、角筒状の回転リング5の上端部で外側筒状体22aの外面の2つの突設物24、24に対応した位置に1つの突設物25とを設け、外側筒状体22aの2つの突設物24、24に、回転リング5の1つの突設物25を嵌め込んで、外側筒状体22aと回転リング5を取り付けて、下側天井挟持部2aとしたものである。
【0024】
このようにすると、下側天井挟持部2aの外側筒状体22aの下端部に角筒状の管、又は、継手の上端部外面に接着剤を塗布して、回転リング5と外側筒状体22aの間に差し込み、角筒状の管、又は、継手の上端部外面を回転リング5の内面に接着することにより、外側筒状体22aの下端部に角筒状の管、又は、継手を接続することができる。

However, if there is a balcony, porch, etc. on the upper side of the eave ceiling, the back side of the balcony, porch, etc. can be seen through the through-hole from the lower side of the eave ceiling. It is usual to provide eaves ceilings.
At that time, a through-hole in the eaves ceiling may be provided immediately below the through-hole in the floor, and a floor-mounted drain from the floor to the eaves ceiling may be provided. There is a case where it is desired to provide a mounting position of the eave ceiling mounting drain in a different location.
However, as shown in FIG. 3, since the eaves ceiling is attached as close as possible to the floor of the balcony, porch, etc., the space between the floor of the balcony, porch, etc. and the eaves ceiling is narrow.
Therefore, when the drain having the same structure as the floor-mounted drain described in Japanese Utility Model Laid-Open No. 59-150821 is used as an eaves ceiling-mounted drain, the floor is located above the eaves ceiling. Since the space between the roof and the eaves ceiling is narrow, the inner cylindrical body cannot be pressed by hand from above.
Therefore, even when trying to screw the female screw of the outer cylindrical body into the male screw of the inner cylindrical body, the inner cylindrical body moves and the female screw of the outer cylindrical body is screwed into the male screw of the inner cylindrical body. There is a problem that the eaves ceiling cannot be firmly held between the upper bowl and the lower bowl.
