【発明の属する技術分野】
本発明は、エアコンの冷媒管のような配管を保護するための配管保護ダクトの接続部材に関するものである。
【０００２】
【従来の技術】
従来からエアコンの冷媒管のような配管を壁面に設けた取り出し口から引き出して壁面に沿って室外機のような機器まで導くように施工している。この場合、壁面７に沿わせる配管は配管保護ダクト１によりカバーして保護するようにしている。ところが、従来の配管保護ダクト１においては、壁面７に段差部８がある場合、図５に示すように、変形自在な蛇腹構造をした接続部材Ａ’により配管保護ダクト１の端部同士を接続して壁面７の段差部８を跨ぐようにしていた。
【０００３】
このような変形自在な蛇腹構造をした接続部材Ａ’で配管保護ダクト１の端部同士を接続して、蛇腹構造の接続部材Ａ’を変形させて壁面７の段差部８を跨ぐものにおいては、蛇腹構造の接続部材Ａ’の変形させた部分が経時的に劣化したり、あるいは、段差部８のみ他の配管保護ダクト１とはちがった蛇腹状の外観をしているため建物の外観が美しくないという問題があった。
【０００４】
【発明が解決しようとする課題】
本発明は上記の点に鑑みてなされたものであり、接続部材部分が経時的な劣化がなく、長期間正常に配管のカバーができ、また、建物の外観が良くなるように施工できる配管保護ダクトの接続部材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に係る配管保護ダクトの接続部材は、略筒状をし且つ所定角度に屈曲し且つ一端部に配管保護ダクト１との接続口２を有する第１接続部材３と、略筒状をし且つ所定角度に屈曲し且つ一端部に第１接続部材３の他端部が内挿又は外挿される連結口４を一端部に有する第２接続部材５とよりなり、第２接続部材５の屈曲方向が第１接続部材３の屈曲方向と逆方向となっていることを特徴とするものである。このような構成とすることで、壁面７に突部のような段差部８がある場合、第２接続部材５を第１接続部材３に接続して構成した接続部材により段差部８を跨ぎ、第１接続部材３を壁面７の段差部８以外の部分に沿って配設した配管保護ダクト１に接続することで、段差部８においても段差部８以外に配置する配管保護ダクト１とほぼ同じ外観とすることができて段差部８において違和感なく配管１０の保護ができるものである。また、接続部材Ａが従来のように蛇腹構造でなく筒状をしているので蛇腹構造のように経時変化により劣化するというようなことがないものである。
【０００６】
また、第１接続部材３と第２接続部材５とをスライド可能に接続することが好ましい。このような構成とすることで、段差部８の巾が現場により異なっても、第１接続部材３と第２接続部材５とをスライドすることで対応できるものである。
【０００７】
また、第２接続部材５の他端部同士を連結させる連結部６を設けることが好ましい。このような構成とすることで、第２の接続部材５同士を確実に接続して第２の接続部材５の端部間が開いたりしないようにできるものである。
【０００８】
【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。
【０００９】
本発明の配管保護ダクトの接続部材Ａは、第１接続部材３と第２接続部材５とにより構成してある。第１接続部材３は略筒状をし且つ所定角度に屈曲し且つ一端部に配管保護ダクト１との接続口２を有したものであり、この第１接続部材３は第１ベース３ａと第１カバー３ｂとに前後方向に２つ割りしてあって、第１ベース３ａと第１カバー３ｂとはいずれか一方に係止部３ｃを設けるとともにいずれか他方に被係止部３ｄを設けて係止部３ｃと被係止部３ｄとを係止することで両者を結合して筒状の第１接続部材３を構成するようになっている。
【００１０】
第２接続部材５は略筒状をし且つ所定角度に屈曲し且つ一端部に第１接続部材３の他端部が内挿又は外挿される連結口４を一端部に有したものであり、この第２接続部材５は第２ベース５ａと第２カバー５ｂとに前後方向に２つ割りしてあって、第２ベース５ａと第２カバー５ｂとはいずれか一方に係止部５ｃを設けるとともにいずれか他方に被係止部５ｄを設けて係止部５ｃと被係止部５ｄとを係止することで両者を結合して筒状の第２接続部材５を構成するようになっている。そして、第２接続部材５の屈曲方向は第１接続部材３の屈曲方向と逆方向となっている。つまり、添付図面に示す実施形態では、第１接続部材３は正面からみて谷折りに屈曲してあり、第２接続部材５は正面から見て山折りに屈曲してある。
【００１１】
上記の構成の２個の第１接続部材３と２個の第２接続部材５とで接続部材Ａを構成するものである。略筒状をした第１接続部材３と略筒状をした第２接続部材５とは、第１接続部材３の他端部を第２接続部材５の一端部の連結口４に内挿又は外挿して接続するものであるが、この場合、第１接続部材３と第２接続部材５とはスライド自在に内挿又は外挿して接続してある。ここで、図３に示すように、第１接続部材３の第１ベース３ａの他端部又は第２接続部材５の第１ベース５ａの一端部の内挿又は外挿箇所において、いずれか一方に接続方向に長い長孔１１を設け、いずれか他方に孔１２を設け、長孔１１、孔１２にボルト１３を通してナット１４で締め付けるのであるが、ナット１４を緩めてボルト１３を長孔１１に沿ってスライドさせることで、第１接続部材３と第２接続部材５との内挿又は外挿深さを自由に調整して接続できるものである。第２接続部材５の他端部同士の接続は、図４に示すように、一方の第２接続部材５の第２ベース５ａの他端部に孔１５ａと孔１５ｂ付き突片１５ｃを設け、他方の第２接続部材５の第２ベース５ａの他端部に同様に孔１５ａと孔１５ｂ付き突片１５ｃを設け、第２ベース５ａの他端部同士を突き合わせた状態で、突片１５ｃが隣りの第２ベース５ａの表面に重ねられて孔１５ｂと孔１５ａとを連通させ、この連通した孔１５ｂ、孔１５ａにボルト１６を挿入してナット１７を締結することで接続するものである。このようにして２個の第２接続部材５を接続するとともに両第２接続部材５の各端部にそれぞれ第１接続部材３を接続することで配管保護ダクト１同士を接続するための接続部材Ａを構成するのである。
【００１２】
上記のような２個の第１接続部材３と２個の第２接続部材５とで構成した接続部材Ａを用いて配管の保護をするには以下のようにするものである。
【００１３】
すなわち、壁面７に設けた引き出し孔２０から引き出した配管１０をエアコン室外機１８まで壁面７に沿わせて配設する場合、該配管１０を壁面７部分においては壁面７に配置して取付ける筒状をした配管保護ダクト１内に通すことで、配管１０の保護をするものである。なお、引き出し孔２０部分においては配管１０の引き出し部分は図２に示すように引き出し口カバー２１により覆うものである。この引き出し口カバー２１は配管保護ダクト１が接続される。配管保護ダクト１は壁面７に固定手段により取付けられるベース体１ａと、ベース体１ａに対して係止手段により着脱自在に取付けられるカバー体１ｂとを組み合わせて筒状に形成してある。ここで、図１、図２に示すように、例えば１階壁面と２階壁面との間のボーダのように壁面７に突出する段差部８がある場合、段差部８の上下両側に位置する各配管保護ダクト１の一端部にそれぞれ上下の第１接続部材３の接続口２を内挿又は外挿して接続し、上下の第１の接続部材３の他端部にそれぞれ第２接続部材５の連結口４を内挿又は外挿し、また、上下の第２の接続部材５の他端部同士を接続するものである。このようにすることで、２個の第１接続部材３と２個の第２接続部材５とで構成した接続部材Ａで段差部８を跨ぐいで段差部８以外の平坦な壁面７に配設した配管保護ダクト１の両端部同士を接続することができるものであり、段差部８においては配管１０が上記段差部８を跨いで両側の配管保護ダクト１に接続される上記略筒状をした接続部材内に通されて保護されるものである。
【００１４】
上記実施形態においては２個の第１接続部材３と２個の第２接続部材５とで構成した接続部材Ａで段差部８を上下方向に跨いで配管保護ダクト１の両端部同士を接続した例を示したが、壁面７に柱の外面部などが突出した縦方向の段差部８がある場合には、上記の２個の第１接続部材３と２個の第２接続部材５とで構成した接続部材で段差部８を横方向に跨いで配管保護ダクト１の両端部同士を接続するものである。
【００１５】
そして、いずれの実施形態においても、段差部８の巾が現場により異なる場合には、第１接続部材３と第２接続部材５とをスライドすることで対応するものである。
【００１６】
【発明の効果】
上記のように本発明の請求項１記載の発明にあっては、略筒状をし且つ所定角度に屈曲し且つ一端部に配管保護ダクトとの接続口を有する第１接続部材と、略筒状をし且つ所定角度に屈曲し且つ一端部に第１接続部材の他端部が内挿又は外挿される連結口を一端部に有する第２接続部材とよりなり、第２接続部材の屈曲方向が第１接続部材の屈曲方向と逆方向となっているので、壁面に突部のような段差部がある場合、第２接続部材を第１接続部材に接続して構成した接続部材により段差部を跨ぎ、第１接続部材を壁面の段差部以外の部分に沿って配設した配管保護ダクトに接続することで、段差部においても段差部以外に配置する配管保護ダクトとほぼ同じ外観とすることができて段差部において違和感なく配管の保護ができるものであり、また、接続部材が従来のように蛇腹構造でなく筒状をしているので蛇腹構造のように経時変化により劣化するというようなことがなく、この結果、長期間にわたって段差部における配管の保護が良好な外観を維持しながら確実に保護できるものである。

[Means for Solving the Problems]
In order to solve the above-mentioned problem, the connection member of the pipe protection duct according to the present invention has a substantially cylindrical shape, is bent at a predetermined angle, and has a connection port 2 with the pipe protection duct 1 at one end. And a second connecting member 5 having a substantially cylindrical shape, bent at a predetermined angle, and having a connection port 4 at one end portion where the other end portion of the first connection member 3 is inserted or externally inserted at one end portion, The bending direction of the second connection member 5 is opposite to the bending direction of the first connection member 3. By having such a configuration, when there is a stepped portion 8 such as a protrusion on the wall surface 7, the stepped portion 8 is straddled by the connecting member configured by connecting the second connecting member 5 to the first connecting member 3, By connecting the first connecting member 3 to the pipe protection duct 1 disposed along the portion other than the stepped portion 8 of the wall surface 7, the stepped portion 8 is substantially the same as the pipe protective duct 1 disposed other than the stepped portion 8. The pipe 10 can be protected without a sense of incongruity at the stepped portion 8. Further, since the connecting member A has a cylindrical shape instead of the bellows structure as in the prior art, it does not deteriorate due to a change with time like the bellows structure.
[0006]
Moreover, it is preferable to connect the 1st connection member 3 and the 2nd connection member 5 so that sliding is possible. By adopting such a configuration, even if the width of the stepped portion 8 varies depending on the site, the first connecting member 3 and the second connecting member 5 can be slid.
