Description

【０００１】
【発明の属する技術分野】
本発明は、空調用配管、ガス導管、給湯配管、或いは電線等の長尺体を見栄え良く覆うカバーに係り、詳しくは、カバー固定対象部側に固定されるカバーベースと、このカバーベースとの間に長尺体を収容自在なスペースを確保する状態にカバーベースに対して着脱自在なカバー部材とを備えて成る長尺体カバー、並びにその長尺体カバーの一対を、長尺体長手方向に隣接させて接続してある長尺体カバーの接続部構造に関するものである。
【０００２】
【従来の技術】
室内の壁面に沿って配管される給湯用の管や電気配線、室内機と室外機とを接続する空調用配管等は体裁を構わない無骨なものであり、一定間隔毎に装備されるクランプを伴なった状態での外観はあまり芳しいものではないため、近年では、配管を覆うカバーを設けることにより、内装される長尺体の保護と見栄えの改善を図ることが標準仕様になりつつある。
【０００３】
配管カバーを用いる場合、配管長さが長く、所定長さの配管カバーを繋ぎ合せて対処するとか、エルボ部分では屈曲カバーと直線カバーとを繋ぐといった具合に、カバーどうしを継ぎ足す等の接続部が必要になることも多い。従来、そのような接続部は、突き合わせて対向配置される配管カバーの端部どうしに亘って、隠しカバーを外嵌させて装着する手段が採られていた。
【０００４】
【発明が解決しようとする課題】
隠しカバーを被せて設けることにより、対向配置された配管カバー間の隙間や中の配管類が見えてしまうことを確実に解消できるとか、現場にて寸法合わせして切断された場合の切断面を覆って見栄えを改善できる利点がある。その反面、専用の部品が必要であってコスト的に不利であるとともに、隠しカバー部分は明確に太くなってカバー自体が凹凸したように見えて、却って美観を損ねるおそれもあり、カバーの接続部には改善の余地が残されているものであった。隠しカバーが比較的接近して複数存在するような場合にはその傾向が一層顕著になる。
【０００５】
本発明の目的は、見栄えを改善できる利点を有効に活かしながら、或いはその利点をより強化しながらも廉価に構成できる長尺体カバーの接続部を実現させる点にある。
【０００６】
【課題を解決するための手段】

【００１０】
請求項５の構成は、図１、図１０に例示する如く、長尺体Ｐのストレート部を覆う直線長尺体カバー６と、長尺体Ｐの屈曲部を覆う屈曲長尺体カバーＢ１と、両長尺体カバー６，Ｂ１の隣接間の長尺体部分を覆う状態で接続される連結用の長尺体カバーＢ２とを備え、前記直線長尺体カバー６と屈曲長尺体カバーＢ１及び前記連結用の長尺体カバーＢ２の各々が、カバー固定対象部側に固定されるカバーベース１，ｈ，ｉと、このカバーベース１，ｈ，ｉとの間に長尺体を収容自在なスペースを確保する状態に前記カバーベース１，ｈ，ｉに対して着脱自在なカバー部材２，ｊ，ｋとを備えて成る長尺体カバーであって、

【００１２】
尚、上述のように、図面との対照を便利にするために符号を記したが、該記入により本発明は添付図面の構成に限定されるものではない。
【００１３】
〔作用〕
請求項１の構成によれば、（イ）一方の長尺体カバー端部の外郭形状を先細り状として、他方の長尺体カバー端部に入り込む状態に嵌合させてあるので、これら両者の長尺体長手方向での嵌合長を長短操作することにより、先細り端部の外周部と他方の長尺体端部の内周部との隙間を小さくした状態、又は殆ど無い状態で長尺体カバーを継ぎ足せるようになる。これは、先細りによって両端部間に相対角度が付いていることに因るのであるが、例えば、外嵌側の端部を先拡がり状とする手段に比べて、外側の長尺体カバーの太さを極力太くすること無く嵌合させること、すなわち、長尺体における嵌合部以外の部分の太さと嵌合部の太さとの差をできるだけ小さくすることが可能になる。
【００１４】
（ロ）又、隣合う長尺体カバーどうしが折れ曲がる状態に相対傾斜していると、例えば直管どうしの嵌合部では、折れ曲がり外側における両端部どうしに先拡がり角が生じる状態になり、嵌合外側の端部が内側端部の外周部から大きく離れて隙間が拡大してしまうのに対して、嵌合部における内側端部が先細り状である本願のものでは、その問題となる折れ曲がり外側での両端部どうしが先拡がり状態になり難いので、極力隙間が増大しないようになる。
【００１９】
請求項６の構成によれば、（ト）前記作用（イ）、（ロ）を備えた長尺体カバーを得ることができ、この長尺体カバーの複数を連続して接続することで、長い配管のカバーを行なうことができる。
【００２０】
〔効果〕
請求項１〜５のいずれに記載の長尺体カバーの接続部構造でも、（イ）の作用により、長尺体カバーどうしの接続部が太くなることを抑制しながら、カバー端端部どうしの隙間を小さくして見栄えが改善されるとともに、（ロ）の作用により、長尺体カバーどうしが折れ曲がる状態で接続されても、端部どうしの隙間が拡大されない利点がある。
【００２５】
請求項５に記載の長尺体カバーでは、（ト）の作用により、長尺体カバーどうしの接続部が太くなることを抑制しながら、カバー端端部どうしの隙間を小さくして見栄えが改善されるとともに、長尺体カバーどうしが折れ曲がる状態で接続されても、端部どうしの隙間が拡大されないようにできた。
【００２６】
【発明の実施の形態】
以下、本発明の実施の形態を図面に基づいて説明する。
図１，２に、室内にて配管された給湯管Ｐ（長尺体の一例）の隅部における方向変換部分が示されている。給湯管Ｐは、保護及び見栄えを目的とした配管カバーＢ（長尺体カバーの一例）で覆われており、配管カバーＢは、ストレート管（長尺体のストレート部の例）５を覆う直線配管カバー（直線長尺体カバーの例）６、エルボ管７（長尺体の屈曲部の例）を覆う屈曲配管カバー（屈曲長尺体カバーの例）８、直線配管カバー６と屈曲配管カバー８とに跨る連結カバー９等から構成されている。
【００２７】
室内の隅では、ｅ壁とｆ壁とｇ壁とが交わるところであり、一方の直線配管カバー６はｆ壁に対して取付けられており、他方の直線配管カバー６はｇ壁に対して取付けられている。つまり、向かい合う直線配管カバー６，６は、配管カバーＢに内装される給湯管Ｐの軸心ｘに関して互いに９０度捩じられた姿勢で、かつ、互いに異なる面に取付けられており、後述する理由（ｄ１≠ｄ２の関係。図３参照）によって、三次元的な屈曲配管経路が形成されている。
【００２８】
つまり、一方の直線配管カバー６の軸心ｘ１と、他方の直線配管カバー６の軸心ｘ２とが交わらず、段差ａが付いた状態でのエルボ管７を配管するものである。そこで、断面円形の屈曲配管カバー８と、一対の連結カバー９，９、及び一対の固定ブラケット１０，１０等から、三次元的に曲がる方向転換部分を、その双方の軸心ｘ１，ｘ２が交わらない芯ずれを吸収しながら上手く覆う屈曲カバー機構Ａを構成してある。この実施形態では、屈曲配管カバー８が長尺体カバーＢ１に、かつ、連結カバー９と固定ブラケット１０とで連結用の長尺体カバーＢ２に夫々相当して嵌合部Ｚを形成しているものである。次に、各部品の構造について説明する。
【００２９】
図３に示すように、直線配管カバー６，６は、ｆ壁等の面（ｗ１）にビス４で固定されるカバーベース１と、カバー本体２と、隣合うビス４，４間にてカバー長手方向にスライド移動自在にカバーベース１に係合支持されたクランプ３とから構成されている。カバーベース１にはクランプ３を嵌め入れるための内向きレール部１ａ，１ａと、カバー本体２を嵌め込むための外向き係入部１ｂ，１ｂが形成されている。
【００３０】
クランプ３は、レール部１ａ，１ａに嵌合する脚片３ａ，３ａと、配管Ｐを内嵌保持可能な保持片３ｂ，３ｂを有した管軸方向に短いものであり、１個の直線配管カバー６，６につき複数個装備されている。カバー本体２は、半円弧状の上部２Ａの両側にスカート部２Ｂ，２Ｂを備えた断面逆向き略Ｕ字形状を呈し、係入部１ｂに係合する一対の突起２ａを各スカート部２Ｂに形成してある。
【００３１】
クランプ３は、隣合うビス４どうしの間ではスライド自在であり、その範囲内では管軸方向の配管保持位置を自由に設定することができる。配管Ｐをクランプ３に押し込めば、保持片３ｂ，３ｂが弾性変形して嵌め入れることができる。カバー本体２は、カバーベース１に対して上方から落とし込み操作すれば、カバー本体２が弾性拡径変形して突起２ａ，２ａが係入部１ｂ，１ｂを乗り越えてから係合することができる。その乗り越え時のカバー本体２の外方への変位量ΔＤを、カバー本体２の設置状態において壁面から離しておく必要がある。
【００３２】
図１，４，１０に示すように、Ｌ字状の屈曲配管カバー８は、これの軸心８ｔに沿う面、詳しくは、屈曲軸心８ｔを全て含んだ面を割面とした基カバー８Ａと蓋カバー８Ｂとから成る２分割構造に構成されており、その両側の先端部８ｓには先細り形状となるテーパ面１１が施されている。両カバー８Ａ，８Ｂは、蓋カバー８Ｂが外側となる周縁の段差嵌合部１２と、基カバー８Ａが凹部１３ａで、かつ、蓋カバー８Ｂが凸部１３ｂとなる５箇所の凹凸嵌合部１３とによって嵌合されている。各カバー８Ａ，８Ｂには、直線配管カバー６，６双方の軸心ｘ１，ｘ２が交わる場合（図３のｄ１＝ｄ２であり、図９，１０参照）に、直接壁面にビス止め可能とするための孔を後で形成し易くする凹み１４を形成してある。
【００３３】
図６，１０に示すように、連結カバー９は、円弧形状の上部９Ａの両側にスカート部９Ｂ，９Ｂを備えた断面逆向き略Ｕ字形状を呈し、直線配管カバー側端部の外郭形状を、先細り状となるテーパ面１５に形成し、かつ、屈曲配管カバー側端部の内郭形状を、先拡がり状となるテーパ面１６に形成してある。この内側のテーパ面１６のテーパ角度は、屈曲配管カバー８のテーパ面１１のテーパ角度よりも緩いものに設定されている（図１２参照）。連結カバー９の内面には、屈曲配管カバー８の挿入限界を規定することが可能な内周リブ１７と、各スカート部９Ｂの内側に位置するフック部１８，１８が一体形成されている。
【００３４】
図７，９〜１２に示すように、固定ブラケット１０は、ビス４で壁面に固定される基部１９に、屈曲配管カバー８を係合させるための管軸方向に突出した円弧突起２０、直線配管カバー６，６のカバーベース１の壁面からの浮き上がりを規制して保持する押え面２１、連結カバー９のフック部１８を係止させるための一対の係合部２２，２２、及び、後述する蛇腹カバーＦの端部を引っ掛けて係止するための一対の引掛け部２３，２３を一体形成した多機能部品に構成されている。
【００３５】
円弧突起２０は、基部１９から立ち上がる縦壁２４から突設してあるとともに、縦壁２４の付け根部分の基部１９には、縦壁２４の基部１９からの除去を容易化するための切り込み２５が形成されている。縦壁２４の両側に間隙を持って配置される引掛け部２３は、角孔２６ａを備えて横向きに突出する下側突片２６と、同様に横向きに突出する上側突片２７とで形成されている。係合部２２は、突起２２ａと凹入面２２ｂとを備えて構成されている。
【００３６】
下側突片２６の根元から立ち上げられて上側突片２７を支える一対の脇縦壁２８，２８には、円弧突起２０と同じ中心を有して、かつ、若干径の大きい円弧端面２８ａが形成してある。この円弧端面２８ａは、管軸方向での厚みが先端程薄くなる先細り状に尖らせてあり、長さ方向の途中で寸断された蛇腹カバーＦの蛇腹部分を引っ掛けられるように設定してある。
【００３７】
図８に、仮固定状態の屈曲配管カバー８を本固定するための係止片３０を示す。係止片３０は、屈曲配管カバー８の外径に沿った円弧端面３１ａを有した略三角形の隠し壁３１に、下側突片２６と上側突片２７との間に嵌まり込む側方突片３２を形成して構成されている。側方突片３２には、挿入限界を規定するストッパ３２ａを形成してある。
【００３８】
次に、屈曲カバー機構Ａを用いて屈曲配管部分をカバーリングする手順を説明する。図９に示すように、先ず、ｆ壁とｇ壁の夫々にカバーベース１をビス４を用いて固定し、それらカバーベース１，１の端部のレール部１ａ，１ａに、固定ブラケット１０の押え面２１を嵌め入れる。次いで、一方の固定ブラケット１０のみをｇ壁にビス４で固定して、他方の固定ブラケット１０が動きうる状態で、図１０，１２に示すように、基カバー８Ａの各端部を、各円弧突起２０の外側（壁側）に嵌め入れ、それから他方の固定ブラケット１０をｆ壁にビス４で固定する。
【００３９】
この場合、基カバー８Ａの各端部を各円弧突起２０の外側に嵌め入れてから、両固定ブラケット１０，１０をビス止めするやり方も可能である。但し、一対の係止片３０，３０のうち、ｅ壁とｇ壁側のものは、基カバー８Ａの装着後には取付けることができないので、基カバー８Ａの装着前に嵌め入れておくようにすると良い。
【００４０】
これにより、両カバーベース１，１と両固定ブラケット１０，１０が固定され、かつ、基カバー８Ａが仮固定された状態になり、この状態でストレート管５、エルボ管７、これら両管５，７を接続するソケット管２９から成る給湯管Ｐを、クランプ３を用いてカバーベース１に係止保持させる。このとき、一方のストレート管５の軸心ｘ１と、他方のストレート管５の軸心ｘ２が交わらずに段差ａを生じているので（図２参照）、各カバーベース１，１の最もエルボ管７側のクランプ３，３間における給湯管Ｐの撓みによってその段差ａが吸収される。
【００４１】
次に、図１０に示すように、各カバーベース１，１にカバー本体２を嵌め込んで装着するとともに、蓋カバー８Ｂを基カバー８Ａに嵌め入れて屈曲配管カバー８を形成し、それから壁側でない側の係止片３０を各固定ブラケット１０に装備して、４個の係止片３０により、円弧突起２０の外周面に先細り先端部８ｓを押付け、仮固定状態にある屈曲配管カバー８を本固定させる。そして最後に、各連結カバー９，９を各固定ブラケット１０，１０に嵌め込んで装着することで、コーナー部分における給湯管Ｐの配管及びそのカバーリングが完了する。
【００４２】
本実施形態では、長尺体カバーＢ２としてのカバーベースｉである固定ブラケット１０に対する「カバー固定対象部側」はｆ壁に、長尺体カバーＢ１としてのカバーベースｈである基カバー８Ａに対する「カバー固定対象部側」は固定ブラケット１０に夫々相当するものである。
【００４３】
エルボ管７の両側に存在する直線配管カバー６，６間には、方向が９０度変更されるだけでなく、その曲がり方向に直交する方向に段差ａが付いているので、その段差ａを吸収して屈曲カバー機構Ａは三次元屈曲するような状態になる。屈曲配管カバー８と連結カバー９とは、若干の隙間を見込んだ遊嵌状態での円弧嵌合とされているので、屈曲配管カバー８の軸心８ｔを直線配管カバー６の軸心ｘ１又はｘ２を中心とした相対回動移動が自在（第１融通と定義する）であるとともに、屈曲配管カバー８の軸心８ｔが直線配管カバー６の軸心ｘ１又はｘ２に対して傾く折れ曲がり移動がある程度可能（第２融通と定義する）であり、この２種の融通によって前述の段差ａを吸収できるようになっている。その吸収形態としては次のような状況が考えられる。
【００４４】
< １> 屈曲配管カバー８の一方の端部が連結カバー９に対して管軸心Ｐ周りに回動し、かつ、屈曲配管カバー８の他方の端部が連結カバー９に対して管軸方向で下方に傾く（図１３参照）。これは、一方の連結カバー９部分では第１融通のみが機能し、他方の連結カバー９部分では第２融通のみが機能している状況である。
< ２> 屈曲配管カバー８の両端部が、いずれも各連結カバー９，９に対して管軸心Ｐ周りに回動するとともに管軸方向で傾く。この傾きは、一方は下方に傾き、他方は上方に傾く。これは、いずれの連結カバー９部分でも、第１融通と第２融通の双方が機能している状況である。これら第１融通や第２融通は次のような問題を解決できる利点がある。
【００４５】
すなわち、実公平７−３６２３４号公報の図１に示された従来の屈曲カバー機構では、配管の敷設場所条件によっては、屈曲配管カバーを円滑に装備し難い状態となることがあった。すなわち、図１に示すように、エルボの両側に配置される直線配管カバーが、それらカバーに内装される配管の軸心に関して互いに９０度捩じられた姿勢で、かつ、互いに異なる面に取付けられることにより、一方の直線配管カバーでの設定配管中心と、他方の直線配管カバーでの設定配管中心とが互いに交わらず、三次元的な屈曲配管経路が形成される場合である。それは、次のような原因に因る。
【００４６】
図３に示すように、直線配管カバーは、構造物の面に固定されるカバーベース１と、このカバーベース１に対して着脱自在に取付けられるカバー本体２と、カバーベース１に設けられた配管支持用のクランプ３とから構成されており、全体としての断面形状は、矩形における壁面と反対側の一辺が半円形に丸められた略カマボコ形を呈している。そして、半円形辺を円弧とする径の中心Ｘに配管Ｐが位置するようにクランプ３が形成されており、配管Ｐの直下位置にカバーベース１を壁面に固定するためのビス４が配置されている。
【００４７】
又、種々の配管径に対応可能となるように、配管Ｐの外周とカバー本体２の内周とに所定の間隙ａを設けるとか、カバー本体２をカバーベース１に弾性的に係合させるための外側への膨出変形空間ｂを確保するといった諸条件を満たすように設計すると、カバーベース１の取付対象壁面ｗ１と配管軸心ｘとの間隔ｄ１と、近接する横側方の壁面ｗ２と配管軸心ｘとの間隔ｄ２とには、ｄ１≠ｄ２の関係が生じることとなり、これが前述した原因である。
【００４８】
従って、屈曲配管カバーを直線配管カバーに直接に接続させる構造では、ｄ１≠ｄ２の関係を満たすべく、種々の施工状況に即した偏心量が施された複数種の屈曲配管カバーがその都度必要になるから、いきおい、成形金型が多くなってコスト高になってしまう。そこで、実公平７−３６２３４号公報の図７に示されたもののように、エルボ管部分を覆う断面円形の屈曲カバー本体と、該屈曲カバー本体の端部と直線配管カバーの端部とに亘って外装される連結カバーの一対と、の３部品を用いる構造を踏襲することにより、複数種の屈曲配管カバーを用意すること無く良好にカバーさせることが考えられた。
【００４９】
すなわち、前述したｄ１≠ｄ２の関係によって直線配管カバーと屈曲配管カバーとの接続箇所が傾くとか、両者の隙間が均一に取れない等の接続ずれを、連結カバーで覆うことによって外観を向上できるとともに、屈曲配管カバーと連結カバーとは１種類で良く、部品点数は増えるが金型費を削減できる点で汎用性が備わるようになり、全体としてはコストダウンできる合理的な手段としてである。
【００５０】
しかしながら、前記公報に図７に示された構造そのままでは、前述の３次元的に曲がる屈曲部を見栄え良くカバーすることが依然として難しいことが分かってきたのである。つまり、実公平７−３６２３４号公報の図７に示されたものでは、一対の連結カバーを壁面にビス止め固定し、かつ、屈曲配管カバーは、これと連結カバーとを周溝嵌合させることで相対姿勢が固定された状態で装備される構造であるから、互いに壁面に固定された連結カバーと屈曲配管カバーとの姿勢のずれを吸収する部分が存在しない。
【００５１】
故に、前述したｄ１≠ｄ２が存在する場合には、取付け施工ができない又は行ない難いとか、無理に取付けて周溝嵌合部や屈曲カバー本体を破損させてしまう等の不都合が生じ易いものであり、無理なく円滑に施工できるようにするには更なる改善の余地が残されているものであった。
【００５２】
そこで、本発明のように、内嵌側のカバー端部を先細り状として嵌合させることにより、前記< １> や< ２> で述べたように、長尺体カバーどうしである屈曲カバー本体８と連結カバー９とを、これらの両者の相対折れ曲がり変位や相対角度変位を無理なく吸収しながらも、端部どうしの隙間を小さくして目立たないようにしながら接続できる状態が得られるようになったのである。
【００５３】
〔別実施形態〕
図１５に示すように、直線配管カバー３６，３７どうしを接続するための嵌合部Ｚに本発明を適用しても良い。この場合、直線配管カバー３６，３７単品としては、一方の端部の外郭形状を先細り状の先細り端部３７ａに、かつ、他方の端部を、カバーとしての殆どを占めるカバー本体（先細り部分に続く部分に相当）３６ｂ，３７ｂよりも若干太い拡径端部３６ｃに設定してあり、これらカバー３６，３７は部品としては同一のものである。又、先細り端部３７ａを長い目に形成して、拡径端部３６ｃを、カバー本体３６ｂ，３７ｂと同じ太さ、すなわち、カバー本体３６ｂ，３７ｂの端部として構成させて、カバー接続部が見た目に膨らまないものとしても良い。
【００５４】
図１６に示すように、内嵌側カバー３８の端部の外郭形状を先細り球面状の端部３８ｒとして、対向する両配管カバー３８，３９どうしが多少折れ曲がる状態で接続されることがあっても、外嵌側カバー３９の端部の内周先端と先細り端部３８ｒとの隙間を小さい状態に維持できる嵌合部Ｚを構成しても良い。
【００５５】
又、図１５に示すカバーの接続部構造において、紙面上で左側の配管カバー３６が上で、かつ、紙面上で右側の配管カバー３７が下となる縦向き配置に嵌合部Ｚを構成しても良い。つまり、内嵌側となる先細り端部３７ａを、外嵌側となる拡径端部３６ｃ（又はカバー本体３６ｂ，３７ｂの端部）の下方となるように配置し、雨水やゴミなどの異物が接続部からカバー３６，３７の内側に入り難いようになって、室内や室外を問わずに用いることができる好都合なものとなる。
【００５６】
直線配管カバー６も長尺体カバーＢ（Ｂ１，Ｂ２）であり、そのカバーベース１はカバーベースｈ，ｉに、かつ、カバー本体２はカバー部材ｊ，ｋに夫々相当するものである。

[0002]
[Prior art]
The hot water supply pipes and electrical wiring piped along the wall surface of the room and the air conditioning pipes connecting the indoor unit and the outdoor unit are rugged, and the clamps installed at regular intervals should be attached. Since the appearance in the accompanying state is not so good, in recent years, it has become a standard specification to provide a cover that covers the piping, thereby protecting the long body that is installed and improving the appearance.
[0003]
When using a piping cover, the piping length is long, connect the piping cover of a predetermined length, handle the elbow, connect the bent cover and the straight cover, etc. Is often required. Conventionally, such a connecting portion has been provided with a means for fitting a hidden cover over the ends of pipe covers that are faced to face each other.
[0004]
[Problems to be solved by the invention]
By covering with a hidden cover, it is possible to surely eliminate the gap between the pipe covers arranged in opposition and the piping inside, or to cut the cut surface when it is cut by dimensioning on site There is an advantage that the appearance can be improved by covering. On the other hand, it requires a special part, which is disadvantageous in terms of cost, and the hidden cover part is clearly thicker and the cover itself appears to be uneven, which may adversely affect the aesthetics. There was still room for improvement. This tendency becomes more pronounced when there are a plurality of hidden covers that are relatively close to each other.
[0005]
An object of the present invention is to realize a long body cover connecting portion that can be constructed at low cost while effectively utilizing the advantage of improving the appearance or further strengthening the advantage.

  [Action]
  Claim1'sAccording to the configuration, (a) since the outer shape of one end of the long body cover is tapered to fit into the state of entering the end of the other long body cover, The long body cover is joined in a state in which the gap between the outer peripheral part of the tapered end part and the inner peripheral part of the other long body end part is made small or little by operating the fitting length in the direction. You can add. This is due to the fact that there is a relative angle between the two end portions due to the taper. For example, the outer cover is thicker than the means for making the end portion on the outer fitting side bend. It is possible to fit without increasing the thickness as much as possible, that is, to reduce the difference between the thickness of the portion other than the fitting portion and the thickness of the fitting portion as long as possible.
[0014]
(B) Also, if the adjacent long body covers are inclined relative to each other in a bent state, for example, in a fitting portion between straight pipes, a bend angle is generated between both ends on the outside of the bent portion. Whereas the outer end is far away from the outer peripheral portion of the inner end and the gap is enlarged, the inner end of the fitting portion is tapered, so that the problem is the bent outer side. Since it is difficult for the both end portions in the case to be expanded, the gap is not increased as much as possible.
[0019]
According to the configuration of claim 6, (e) it is possible to obtain a long body cover provided with the actions (b) and (b), and by continuously connecting a plurality of the long body covers, Long piping can be covered.

The appearance is improved by reducing the gap, and the effect of (b) has the advantage that the gap between the end portions is not enlarged even if the long body covers are connected in a bent state.
[0025]
  Claim5In the long body cover described in (2), the effect of (g) improves the appearance by reducing the gap between the cover end ends while suppressing the connection between the long body covers from becoming thicker. Even if the long body covers are connected in a bent state, the gap between the end portions can be prevented from being enlarged.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.
  1 and 2 show a direction changing portion at a corner of a hot water supply pipe P (an example of a long body) piped indoors. The hot water supply pipe P is covered with a piping cover B (an example of a long body cover) for the purpose of protection and appearance, and the piping cover B is a straight pipe.(Example of long straight part)5 straight piping cover(Example of straight long cover)6. Elbow tube 7(Example of bent part of long body)Bent piping cover to cover(Example of bent long body cover)8. The connecting cover 9 extends between the straight piping cover 6 and the bent piping cover 8.
[0027]
At the corner of the room, the e wall, the f wall, and the g wall intersect. One straight piping cover 6 is attached to the f wall, and the other straight piping cover 6 is attached to the g wall. ing. That is, the straight piping covers 6 and 6 facing each other are attached to different surfaces in a posture twisted by 90 degrees with respect to the axis x of the hot water supply pipe P housed in the piping cover B. A three-dimensional bent piping path is formed by the relationship (d1 ≠ d2; see FIG. 3).
[0028]
    In other words, the elbow pipe 7 is piped in a state in which the axis x1 of one straight pipe cover 6 and the axis x2 of the other straight pipe cover 6 do not intersect but with a step a. Therefore, both the axial centers x1 and x2 intersect the direction changing portion that is bent three-dimensionally from the bent pipe cover 8 having a circular cross section, the pair of connecting covers 9 and 9, the pair of fixed brackets 10 and 10, and the like. A bending cover mechanism A that covers well while absorbing a misalignment is configured.

As shown in FIG. 3, the straight piping covers 6 and 6 cover the cover base 1 fixed to the surface (w1) such as the f wall with screws 4, the cover body 2, and the adjacent screws 4 and 4. It comprises a clamp 3 engaged and supported by the cover base 1 so as to be slidable in the longitudinal direction. The cover base 1 is formed with inward rail portions 1a and 1a for fitting the clamp 3 and outward engaging portions 1b and 1b for fitting the cover main body 2.
[0030]
The clamp 3 is short in the tube axis direction having leg pieces 3a, 3a fitted to the rail portions 1a, 1a and holding pieces 3b, 3b capable of holding the pipe P therein, and is one straight pipe. A plurality of covers 6 and 6 are provided. The cover body 2 has a substantially U-shaped cross-section with skirt portions 2B, 2B on both sides of the semicircular upper portion 2A, and a pair of protrusions 2a that engage with the engaging portions 1b are formed on each skirt portion 2B. It is.
[0031]
The clamp 3 is slidable between the adjacent screws 4, and the pipe holding position in the pipe axis direction can be freely set within the range. If the pipe P is pushed into the clamp 3, the holding pieces 3b and 3b can be elastically deformed and fitted. If the cover body 2 is dropped from above with respect to the cover base 1, the cover body 2 can be engaged after the elastic expansion of the cover body 2 and the protrusions 2a and 2a get over the engaging portions 1b and 1b. It is necessary to keep the amount of displacement ΔD outward of the cover body 2 at the time of getting over from the wall surface in the installed state of the cover body 2.
[0032]
As shown in FIGS. 1, 4, and 10, the L-shaped bent pipe cover 8 has a base cover 8A having a plane along the axis 8t, specifically, a plane including all the bent axes 8t as a split surface. And a lid cover 8B. The tip 8s on both sides is provided with a tapered surface 11 having a tapered shape. Both covers 8A and 8B have a step fitting portion 12 on the periphery where the lid cover 8B is on the outside, and five concave and convex fitting portions 13 where the base cover 8A is a concave portion 13a and the lid cover 8B is a convex portion 13b. And is fitted by. Each cover 8A, 8B can be screwed directly to the wall surface when the axes x1, x2 of both the straight piping covers 6, 6 intersect (d1 = d2 in FIG. 3, see FIGS. 9, 10). A recess 14 is formed to facilitate later formation of a hole.
[0033]
  FIG., 10, the connection cover 9 has a substantially U-shaped cross-section with skirt portions 9B, 9B on both sides of the arcuate upper portion 9A, and the outer shape of the end portion of the straight pipe cover is tapered. The inner surface of the bent pipe cover side end portion is formed on the taper surface 16 that is bent forward. The taper angle of the inner tapered surface 16 is set to be looser than the taper angle of the tapered surface 11 of the bent pipe cover 8 (see FIG. 12). On the inner surface of the connecting cover 9, an inner peripheral rib 17 capable of defining the insertion limit of the bent pipe cover 8 and hook portions 18 and 18 positioned inside each skirt portion 9B are integrally formed.
[0034]
  7, 9-12As shown in FIG. 4, the fixed bracket 10 includes a base 19 that is fixed to the wall surface with screws 4 and an arc projection 20 that protrudes in the tube axis direction for engaging the bent pipe cover 8, and covers for the straight pipe covers 6 and 6. A holding surface 21 that regulates and holds the base 1 from the wall surface, a pair of engaging portions 22 and 22 for locking the hook portion 18 of the connecting cover 9, and an end portion of the bellows cover F to be described later. A pair of hooking portions 23, 23 for hooking and locking are formed into a multi-functional part integrally formed.
[0035]
The circular arc protrusion 20 protrudes from the vertical wall 24 rising from the base portion 19, and the base portion 19 of the base portion of the vertical wall 24 has a notch 25 for facilitating removal from the base portion 19 of the vertical wall 24. Is formed. The hooking portion 23 disposed with a gap on both sides of the vertical wall 24 is formed of a lower protruding piece 26 that has a square hole 26a and protrudes sideways, and an upper protruding piece 27 that also protrudes sideways. ing. The engaging portion 22 includes a protrusion 22a and a recessed surface 22b.
[0036]
A pair of side vertical walls 28, 28 raised from the base of the lower protruding piece 26 and supporting the upper protruding piece 27 has an arc end surface 28 a having the same center as the arc protrusion 20 and having a slightly larger diameter. It is formed. The arc end surface 28a is tapered so that the thickness in the tube axis direction becomes thinner toward the tip, and is set so that the bellows portion of the bellows cover F cut off in the length direction can be hooked.
[0037]
  FIG.5 shows a locking piece 30 for permanently fixing the bent pipe cover 8 in the temporarily fixed state. The locking piece 30 is a side protrusion that fits between the lower protruding piece 26 and the upper protruding piece 27 on a substantially triangular hidden wall 31 having an arcuate end surface 31 a along the outer diameter of the bent pipe cover 8. A piece 32 is formed. The side protrusion 32 is formed with a stopper 32a that defines the insertion limit.
[0038]
  Next, a procedure for covering the bent pipe portion using the bent cover mechanism A will be described.FIG.First, the cover base 1 is fixed to each of the f wall and the g wall by using screws 4, and the holding surface of the fixing bracket 10 is fixed to the rail portions 1 a and 1 a at the ends of the cover bases 1 and 1. 21 is inserted. Next, in a state where only one fixing bracket 10 is fixed to the g wall with screws 4 and the other fixing bracket 10 is movable,10 and 12As shown in FIG. 4, each end of the base cover 8A is fitted into the outer side (wall side) of each arc projection 20, and the other fixing bracket 10 is fixed to the f wall with screws 4.
[0039]
In this case, after fixing each end part of the base cover 8A to the outer side of each circular arc protrusion 20, the method of screwing both the fixing brackets 10 and 10 is also possible. However, the e-wall and g-wall side of the pair of locking pieces 30 and 30 cannot be attached after the base cover 8A is attached, so that they are fitted before the base cover 8A is attached. good.
[0040]
  As a result, the cover bases 1 and 1 and the fixing brackets 10 and 10 are fixed, and the base cover 8A is temporarily fixed. In this state, the straight pipe 5, the elbow pipe 7, and the pipes 5, A hot water supply pipe P composed of a socket pipe 29 to which 7 is connected is locked and held on the cover base 1 using the clamp 3. At this time, since the axis x1 of one straight pipe 5 and the axis x2 of the other straight pipe 5 do not intersect, a step a is generated (see FIG. 2).Cover baseThe level difference a is absorbed by the bending of the hot water supply pipe P between the clamps 3 and 3 closest to the elbow pipes 1 and 1.
[0041]
  Next, as shown in FIG.Cover base1 and 1, the cover body 2 is fitted and attached, and the lid cover 8B is fitted into the base cover 8A to form the bent pipe cover 8, and then the locking piece 30 on the side that is not on the wall side is attached to each fixing bracket 10. Equipped with the four locking pieces 30, the tapered tip 8 s is pressed against the outer peripheral surface of the arc projection 20, and the bent pipe cover 8 in the temporarily fixed state is permanently fixed. Finally, the connecting covers 9 and 9 are fitted into the fixing brackets 10 and 10 to complete the piping of the hot water supply pipe P in the corner portion and the covering thereof.
[0042]
In the present embodiment, the “cover fixing target portion side” for the fixing bracket 10 that is the cover base i as the long body cover B2 is “f” on the wall f, and the “base cover 8A that is the cover base h as the long body cover B1” is “ The “cover fixing target part side” corresponds to the fixing bracket 10.
[0043]
Between the straight pipe covers 6 and 6 existing on both sides of the elbow pipe 7, not only the direction is changed by 90 degrees, but also a step a is provided in a direction perpendicular to the bending direction, so that the step a is absorbed. Thus, the bending cover mechanism A is in a state of being three-dimensionally bent. Since the bent pipe cover 8 and the connecting cover 9 are arc-fitted in a loose fitting state with some clearance, the axis 8t of the bent pipe cover 8 is connected to the axis x1 or x2 of the straight pipe cover 6. Is relatively movable (defined as first accommodation), and the bent pipe cover 8 has an axial center 8t that can be bent to a certain degree with respect to the axial center x1 or x2 of the straight pipe cover 6. (It is defined as second accommodation), and the above-described step a can be absorbed by these two types of accommodation. The following situations can be considered as the absorption form.
[0044]
<1> One end of the bent pipe cover 8 rotates around the tube axis P with respect to the connecting cover 9, and the other end of the bent pipe cover 8 moves in the tube axis direction with respect to the connecting cover 9. (See FIG. 13). This is a situation in which only the first interchange is functioning in one connecting cover 9 portion and only the second interchange is functioning in the other connecting cover 9 portion.
<2> Both ends of the bent pipe cover 8 rotate around the tube axis P with respect to the connection covers 9 and 9 and are inclined in the tube axis direction. As for this inclination, one inclines downward and the other inclines upward. This is a situation where both the first accommodation and the second accommodation are functioning in any connecting cover 9 portion. These 1st accommodation and 2nd accommodation have the advantage which can solve the following problems.
[0045]
That is, in the conventional bent cover mechanism shown in FIG. 1 of the Japanese Utility Model Publication No. 7-36234, depending on the installation location conditions of the pipe, it may be difficult to smoothly install the bent pipe cover. That is, as shown in FIG. 1, the straight piping covers arranged on both sides of the elbow are attached to different surfaces in a posture in which they are twisted by 90 degrees with respect to the axial center of the piping built in the covers. This is a case where the set pipe center in one straight pipe cover and the set pipe center in the other straight pipe cover do not cross each other and a three-dimensional bent pipe path is formed. This is due to the following causes.
[0046]
As shown in FIG. 3, the straight pipe cover includes a cover base 1 fixed to the surface of the structure, a cover body 2 that is detachably attached to the cover base 1, and a pipe provided on the cover base 1. It is comprised from the clamp 3 for support, and the cross-sectional shape as a whole is exhibiting the substantially scallop shape by which the one side on the opposite side to the wall surface in a rectangle was rounded by the semicircle. The clamp 3 is formed so that the pipe P is located at the center X of the diameter having a semicircular side as an arc, and a screw 4 for fixing the cover base 1 to the wall surface is disposed immediately below the pipe P. ing.
[0047]
In addition, a predetermined gap a is provided between the outer periphery of the pipe P and the inner periphery of the cover body 2 so that various pipe diameters can be accommodated, or the cover body 2 is elastically engaged with the cover base 1. If it is designed so as to satisfy the various conditions such as securing the bulging deformation space b to the outside, the distance d1 between the wall surface w1 to be attached to the cover base 1 and the pipe axis x, and the adjacent lateral wall surface w2 The relationship d1 ≠ d2 occurs in the interval d2 with the pipe axis x, which is the cause described above.
[0048]
Therefore, in the structure in which the bent pipe cover is directly connected to the straight pipe cover, a plurality of types of bent pipe covers having eccentric amounts corresponding to various construction situations are required each time in order to satisfy the relationship of d1 ≠ d2. As a result, the number of molds increases and the cost increases. Therefore, as shown in FIG. 7 of the Japanese Utility Model Publication No. 7-36234, the bent cover main body having a circular cross section covering the elbow pipe portion, the end of the bent cover main body, and the end of the straight piping cover are covered. By following the structure using three parts of a pair of connecting covers to be externally mounted, it was conceived to cover well without preparing a plurality of types of bent pipe covers.
[0049]
That is, the appearance can be improved by covering the connection shift such as the connection portion between the straight pipe cover and the bent pipe cover incline due to the above-described relationship of d1 ≠ d2 or the gap between the two cannot be made uniform with the connecting cover. The bent pipe cover and the connecting cover may be one type, and the number of parts increases, but the versatility comes to be able to reduce the cost of the mold, and as a rational means for reducing the cost as a whole.
[0050]
However, it has been found that if the structure shown in FIG. 7 in the above publication is used as it is, it is still difficult to cover the above-described three-dimensional bent portion with a good appearance. That is, in the one shown in FIG. 7 of the Japanese Utility Model Publication No. 7-36234, a pair of connecting covers are fixed to the wall surface with screws, and the bent pipe cover is fitted to the connecting cover with a circumferential groove. Therefore, there is no portion that absorbs the deviation of the posture between the connecting cover and the bent pipe cover that are fixed to the wall surface.
[0051]
Therefore, in the case where d1 ≠ d2 described above exists, it is easy to cause inconveniences such as inability to install or difficult to perform, or forcibly mounting and damaging the peripheral groove fitting portion and the bent cover body. However, there was still room for further improvement in order to enable smooth construction without difficulty.
[0052]
Therefore, as described in the above <1> and <2>, the bent cover body 8 which is the long body cover is formed by fitting the cover end portion on the inner fitting side in a tapered shape as in the present invention. And the connecting cover 9 can be connected to each other while making the gap between the ends small and inconspicuous, while absorbing the relative bending displacement and relative angular displacement of both of them without difficulty. It is.
[0053]
[Another embodiment]
As shown in FIG. 15, the present invention may be applied to the fitting portion Z for connecting the straight pipe covers 36 and 37. In this case, as the straight piping covers 36 and 37 alone, the outer shape of one end portion is a tapered tapered end portion 37a, and the other end portion is a cover body that occupies most of the cover (the tapered portion). (Corresponding to the following part) 36b and 37b are set to be slightly thicker end portions 36c, and these covers 36 and 37 are the same parts. Further, the tapered end portion 37a is formed in a long shape, and the enlarged diameter end portion 36c is configured to have the same thickness as the cover main bodies 36b and 37b, that is, the end portions of the cover main bodies 36b and 37b. It may be something that does not swell visually.
[0054]
As shown in FIG. 16, even if the outer pipes 38 and 39 facing each other are connected in a slightly bent state, the outer shape of the end of the inner fitting side cover 38 is a tapered spherical end 38r. The fitting portion Z that can maintain the gap between the inner peripheral tip of the end portion of the outer fitting side cover 39 and the tapered end portion 38r in a small state may be configured.
[0055]
Further, in the cover connecting portion structure shown in FIG. 15, the fitting portion Z is configured in a vertical arrangement in which the left pipe cover 36 is on the top and the right pipe cover 37 is on the bottom. May be. In other words, the tapered end portion 37a on the inner fitting side is disposed below the enlarged diameter end portion 36c (or the end portion of the cover main body 36b, 37b) on the outer fitting side, and foreign matters such as rainwater and dust are collected. It becomes difficult to enter the inside of the covers 36 and 37 from the connection portion, and it becomes convenient that it can be used both indoors and outdoors.
[0056]
The straight piping cover 6 is also a long body cover B (B1, B2). The cover base 1 corresponds to the cover bases h and i, and the cover body 2 corresponds to the cover members j and k, respectively.
