【発明の属する技術分野】
本発明は長尺体カバーの接続部に関し、詳しくは、構造物の壁面に沿って配設される長尺体を覆う第一カバー部材と、前記第一カバー部材と前記壁面との間に介装される第一スペーサとで構成される第一保護カバーに対して、前記壁面に取り付けられた第一保護カバーに支持される配管、配線等の長尺体を前記第一保護カバーの外側で保護し、前記長尺体を覆う第二カバー部材と、前記第二カバー部材と前記壁面との間に介装される第二スペーサとで構成される第二保護カバーを接続する長尺体カバーの接続部に関する。
【０００２】
【従来の技術】
従来、構造物の壁面に沿って配設される長尺体は、保護カバーにより覆われて保護されている。この保護カバーには、時として前記保護カバーと前記壁面との間にスペーサが介装されている。こうしたスペーサを介装した保護カバーの接続部においては、前記長尺体を覆う第一カバー部材と、前記第一カバー部材と前記壁面との間に介装される第一スペーサとで構成される第一保護カバーに対して、前記壁面に取り付けられた第一保護カバーに支持される長尺体を前記第一保護カバーの外側で保護し、前記配管又は配線を覆う第二カバー部材と、前記第二カバー部材と前記壁面との間に介装される第二スペーサとで構成される第二保護カバーが接続される。前記第一スペーサと前記第二スペーサとは夫々の端面を接当させるだけで前記壁面に取り付けられ、前記第一スペーサと前記第二スペーサとに第一保護カバーと第二保護カバーとが夫々係止固定され、その接続部を接続カバー材で外側から覆うことが行われている。
【０００３】
【発明が解決しようとする課題】
ところが、上記従来構成の長尺体カバーの接続部においては、前記第一スペーサと前記第二スペーサとは夫々の端面を接当させるだけで前記壁面に取り付けられるから、前記第一スペーサに対する前記第二スペーサの芯合わせを確実に行ための労力と時間が必要であるという問題を有していた。また、その接続部を外側から覆う接続カバー材が前記第一カバー部材と第二カバー部材とに十分に密着せず、前記接続部を十分に保護することができない場合があった。
【０００４】
そこで、本発明の目的は、接続するスペーサ同士の芯合わせが極めて容易で、簡単に接続でき、その接続部においての保護機能を十分に維持できる長尺体カバーの接続部を提供する点にある。
【０００５】
【課題を解決するための手段】
【０００６】
〔本発明の特徴構成〕
本発明に係る長尺体カバーの接続部は、構造物の壁面に沿って配設される長尺体を覆う係止固定自在な第一カバー部材とベース部材、及び、前記ベース部材と前記壁面との間に介装される第一スペーサとで構成される第一保護カバーに対して、前記第一保護カバーの外側で前記長尺体を覆う係止固定自在な第二カバー部材と係止部材、及び、前記係止部材と前記壁面との間に介装される第二スペーサとで構成される第二保護カバーを接続する長尺体カバーの接続部であって、夫々に以下のような特徴を備えるものである。
【０００７】
請求項１に係わる本発明の長尺体カバーの接続部の特徴構成は、第二カバー部材の接続側端部を第一カバー部材の接続側端部に外嵌自在に構成すると共に、第二スペーサの接続側端部に、第一スペーサの接続側端部に接当自在で、前記第一スペーサの接続側端部を内嵌自在な凹入部を形成し、前記凹入部に前記第一保護カバー内に支持する長尺体の配置基準線に直交する接当面を形成すると共に、その接当面の両側に接当突起を形成して、その内側対向面を前記第一スペーサの両外側面に対して接当自在とし、さらに、前記第二スペーサには、当該第二スペーサを壁面に取付けるための取付孔と、前記係止部材に形成のネジ孔に挿通されたネジで係止部材とともに第二スペーサを壁面に取付けるためのネジ貫通孔とを形成してある（第１特徴構成）点にある。
これを図３に示す例に沿って説明すれば、図示の例においては、第二カバー部材５の接続側端部を第一カバー部材２の接続側端部に外嵌自在に構成すると共に、第二スペーサ６の接続側端部に第一スペーサ３の接続側端部に接当自在で、前記第一スペーサ３の接続側端部を内嵌自在な凹入部１０を形成し、前記凹入部１０に第一保護カバー１内に支持する長尺体の配置基準線に直交する接当面１１を形成すると共に、その接当面１１の両側に接当突起１２を形成して、その内側対向面１２ａを前記第一スペーサ３の両外側面に対して接当自在とし、さらに、前記第二スペーサ６には、当該第二スペーサ６を壁面に取付けるための取付孔１７と、前記係止部材２８に形成のネジ孔２６に挿通されたネジで係止部材２８とともに第二スペーサ６を壁面に取付けるためのネジ貫通孔１８とを形成してある。
【０００８】
請求項２に係わる本発明の長尺体カバーの接続部の特徴構成は、上記第１特徴構成に加えて、第一スペーサの壁面に接当する下方側に溝を形成し、前記溝の側壁に接当可能で、且つ、前記溝内に挿入自在な突出片部を、前記接当面に突出形成してある（第２特徴構成）点にある。これを図８に示す例に沿って説明すれば、図示の例においては、第一スペーサ３の下方側、即ち壁面Ｗに接当する側に溝２２を形成し、前記溝２２の側壁に接当可能で、且つ、前記溝２２内に挿入自在な突出片部１３を、第二スペーサ６に形成した凹入部１０の接当面１１に突出形成するのである。
【０００９】
請求項３に係わる本発明の長尺体カバーの接続部の特徴構成は、上記第１特徴構成に加えて、第一スペーサの壁面に接当する下方側に溝を形成し、前記溝内に挿入自在で、且つ、前記溝の両側壁部を一対の接当突起夫々との間で狭持自在な一対の狭持突起部を、接当面に突出形成してある（第３特徴構成）点にある。これを図９に示す例に沿って説明すれば、図示の例においては、第一スペーサ３の下方側、即ち壁面Ｗに接当する側に溝２２を形成し、前記溝２２内に挿入自在で、且つ、前記溝２２の両側壁部２３を第二スペーサ６に形成した凹入部１０における接当面１１の両側に形成した一対の接当突起１２夫々との間で狭持自在な一対の狭持突起部１４を、前記接当面１１に突出形成するのである。
【００１０】
〔特徴構成の作用及び効果〕
上記本発明に係る長尺体カバーの接続部によれば、第一スペーサと第二スペーサとの間で芯合わせを容易としてあり、結果として、第一保護カバーと第二保護カバーとの内に支持する長尺体の配置計画線に対する前記第一保護カバーと前記第二保護カバーのずれを防止できるもので、夫々に、以下のような独特の作用効果を奏する。
【００１１】
上記本発明に係わる長尺体カバーの接続部の第１特徴構成によれば、労を多くすることなく、長尺体カバーの保護カバー同士を接続でき、且つ、芯出しできて、その保護機能も十分に維持できる。つまり、第二スペーサの凹入部に第一スペーサの接続側端部を嵌入することで、簡単に第一スペーサと第二スペーサとの間の配置基準線を一致させることができる。しかも、前記第二スペーサの凹入部に形成した接当面を配置基準線に直交させてあるから、前記第一スペーサの接続側端部が正確に加工されておれば、接当させるだけで芯出しすることができ、しかも、両側の接当突起の間に前記第一スペーサの接続側端部を嵌入させるから、両者の配置基準線の横ずれを防止することが可能になる。これを図３に示した例に沿って説明すると、第一保護カバー１を構成する第一スペーサ３の接続側端部に対して、第二保護カバー４を構成する第二スペーサ６の接続側端部に凹入部１０を形成し、その凹入部１０に、前記第一スペーサ３の接続側端部を嵌入自在に構成してあるから、前記第一スペーサ３の接続側端部を前記凹入部１０の接当突起１２の間に内嵌するだけで、前記第一スペーサ３と前記第二スペーサ６との間での配置基準線Ｌのずれを防止できる。また、前記凹入部１０の接当面１１を前記配置基準線Ｌに直交させてるから、前記第一スペーサ３の接続側端部が正確に加工されておれば、これを前記接当面１１に接当させるだけで、確実な芯出しができる。しかも、前記第一スペーサ３の接当側端部の加工が正確でなくても、その接当側端部を前記接当突起１２の間に嵌入することで、方向付けも可能であり、芯出しが容易となる。さらに、前記第一保護カバー１を構成する第一カバー部材２の接続側端部に対して、前記第二保護カバー４を構成する第二カバー部材５を外嵌自在に構成してあることで、接続部でカバー部材を重ね合わすことになるから、接続部においても、内部に支持する長尺体を十分に保護できるようになる。
【００１２】
上記本発明に係わる長尺体カバーの接続部の第２特徴構成によれば、上記第１特徴構成の作用効果を奏する中で、接続部を有する長尺体カバーの壁面への取り付けがさらに容易となる。つまり、第二スペーサの接当面に突出形成した突出片部を、第一スペーサを取り付ける壁面側に形成した第一スペーサの溝内に挿入することで、前記接当面に突出形成した接当突起による芯合わせを補強できる。しかも、前記接当突起が前記第一スペーサの溝内で、前記壁面との間に位置することで、前記第一スペーサと前記壁面との間で第二スペーサを仮保持することも可能となる。これを図８に示した例に沿って説明すると、第一スペーサ３の下方側、即ち壁面Ｗに接当する側に形成した溝２２内に前記第二スペーサ６の凹入部１０における接当面１１に突出形成した突出片部１３を挿入することで、その側方で前記溝２２の側壁面に接当させることができて、前記接当面１１に突出形成した接当突起１２による前記第一スペーサ３に対する位置合わせ機能を補強できる。しかも、前記溝２２内における前記第一スペーサ３と前記壁面Ｗとの間で、挿入された前記突出片部１３を保持できるから、前記第二スペーサ６を前記第一スペーサ３に仮保持させることができ、前記第一スペーサ３及び前記第二スペーサ６を壁面に組み付けることが容易となる。長尺体は前記第一スペーサ３及び前記第二スペーサ６の上で支持され、第一カバー部材２及び第二カバー部材５はこの第一スペーサ３及び第二スペーサ６に係止固定されるのである。
【００１３】
上記本発明に係わる長尺体カバーの接続部の第３特徴構成によれば、上記第１特徴構成の作用効果を奏する中で、接続部における長尺体カバーの壁面への取り付けがさらに容易となる。つまり、第二スペーサの凹入部における接当面の両側に突出形成された一対の接当突起と、前記接当面に突出形成された一対の狭持突起との間に第一スペーサの溝の両側壁部を夫々狭持することで、前記第二スペーサを前記第一スペーサに取り付けることが可能になる。これを図９に示した例に沿って説明すると、第一スペーサ３の下方側、即ちこれを取り付ける壁面Ｗ側に溝を形成し、第二スペーサ６の接続側端部に形成した凹入部１０に、前記第一スペーサ３の接続側端部を接当自在な接当面１１を形成してあり、その接当面１１の両側に形成された一対の接当突起１２と前記接当面１１に突出形成された狭持突起部１４との間に、前記第一スペーサ３の溝２２の両側壁部２３を狭持することで、前記第二スペーサ６は、前記第一スペーサ３に仮付けできるのである。
【００１４】
その結果、長尺体を保護する長尺体カバーの保護カバー同士を簡単に接続で、その接続部においても十分な保護機能を発揮させることができる。
【００１５】
尚、上記の本発明の課題を解決するための手段の説明において、図面を参照し、図面との対照を便利にするために符号を記したが、上記図面の参照及び符号の記入により本発明が参照図面他添付図面の構成に限定されるものではない。
【００１６】
【発明の実施の形態】
以下、本発明に係わる長尺体カバーの接続部の実施の形態の一例について図面を参照しながら説明する。
【００１７】
本発明に係る長尺体カバーにおいては、例えば図１に示すように、接続される接続部の一方側には直線カバーとしての第一保護カバー１が配置され、構造物の壁面Ｗに沿って配設される長尺体を覆う第一カバー部材２と、前記第一カバー部材２と前記壁面Ｗとの間に介装される第一スペーサ３とで構成される。前記接続部の他方側の第二保護カバー４は、前記壁面Ｗに取り付けられた第一保護カバー１に支持される配管、配線等の長尺体を前記第一保護カバー１の外側で保護し、前記長尺体を覆う第二カバー部材５と、前記第二カバー部材５と前記壁面Ｗとの間に介装される第二スペーサ６とで構成される。図示の例においては、長尺体カバーは長尺体として配管を覆っている。前記第二保護カバー４は、その他方側に配置された直線カバーである第三保護カバー７を前記第一保護カバー１に接続する接続カバーとして構成してある。前記各保護カバー内においては、図２にその代表として第二保護カバー４の断面を示すように、内部に長尺体としての配管が支持される。そして、前記第三保護カバー７と前記第二保護カバー４との間の接続部は、前記第一保護カバー１と前記第二保護カバー４との間の接続部と同様に構成される。前記第三保護カバー７は、前記第一保護カバー１と同様に、前記壁面Ｗに取り付けられる第三スペーサ９と、前記第三スペーサ９に係止固定自在な第三カバー部材８とで構成される。
【００１８】
前記第二カバー部材５の両端部は、図１に示したように、接続側端部として前記第一カバー部材２及び前記第三カバー部材８の接続側端部に夫々外嵌自在に構成する。そして、図３及び図４に示すように、前記第一スペーサ３、第二スペーサ６及び第三スペーサ９には、夫々に保護する長尺体の配置軸線に対応する配置基準線Ｌを表面に罫書きしてある。前記第二スペーサ６の両側端部である接続側端部には、前記第一スペーサ３及び前記第三スペーサ９の接続側端部に夫々接当自在で、前記第一スペーサ３及び前記第三スペーサ９の接続側端部を内嵌自在な凹入部１０を夫々に形成する。この凹入部１０には、図５に示すように、前記第一保護カバー１又は前記第三保護カバー７内に支持する長尺体の夫々の配置軸線に対応して罫書きされた配置基準線Ｌの延長線に対応する前記第二保護カバー４の両側端部における配置基準線Ｌに直交する接当面１１が形成される。そして、その接当面１１の両側に接当突起１２を形成して、その内側対向面１２ａを前記第一スペーサ３又は第三スペーサ９の両外側面に対して接当自在とする。つまり、第一スペーサ３同士を重ね合わせたときに、横ずれなく重ねることができるようにしてある。
【００１９】
前記第一スペーサ３（或いは前記第三スペーサ９）には、図５に示したように、裏面、即ち、それを取り付ける壁面Ｗ側の面に、平行で、且つ全長に亘る三条の溝２２を形成してある。そして、各溝２２を仕切るリブは、外側に形成された前記溝２２の側壁部２３と共に前記壁面Ｗに接当するように形成されている。前記壁面Ｗに取り付けるための取付孔１７が前記配置基準線Ｌ上の複数箇所に形成されており、その表面の配置基準線Ｌに沿う両側に、前記第一カバー部材２を係止固定自在に取り付けるベース部材２５の側部に接当自在な位置決め突条２４を突出形成してある。これら位置決め突条２４は、軸線を合わせて取り付けられるべき前記ベース部材２５の側部に接当可能に配置してある。これら位置決め突条２４により幅方向の位置ずれを規制した状態で、前記第一スペーサ３に貫通形成してあるネジ貫通孔（図示省略）に位置合わせして貫通してあるネジ孔（図示省略）にタッピングネジ等のネジを挿通して、前記第一スペーサ３と共に、前記ベース部材２５がその軸線を合わせた状態で前記壁面Ｗに取り付けられるのである。これら位置決め突条２４は、図５に示したように、何れも、その外側面を裏面側に形成された両外側の溝２２の外側壁面２２ａに位置を合わせてある。尚、前記ベース部材２５は、前記第一スペーサ３を介装することなく壁面に取り付けることができるように構成されたものである。このベース部材２５には、図３及び図４に示したように、これに係止固定可能に構成した配管を支持自在な支持部材２７が所要の箇所に係止固定される。
【００２０】
また、図３及び図４に示したように、前記第二スペーサ６の表面にも、前記第二カバー部材５を係止固定自在な係止部材２８を位置決め可能な位置決め突条１５と、位置決め突起１６とを突出形成してある。前記第二カバー部材５を前記第二スペーサ６に接当させた状態で係止固定するために、前記係止部材２８には、前記第二カバー部材５を係合させるための係合部２９を備えている。この係合部２９には、下端部を除く外側面の外周部を残して凹部２９ａを形成してあり、その上端部に、前記第二カバー部材５の内面に形成した係合突起２１（図３参照）を係合させるようにしてある。このように構成して、図４（イ）に示すように、前記各スペーサ３，６，９を前記壁面Ｗに仮固定した後、図４（ロ）に示すように、前記第一スペーサ３及び前記第三スペーサ９の表面上に位置合わせして夫々ベース部材２５を、前記第二スペーサ６の表面上に位置合わせして係止部材２８を配置して、前記各スペーサ３，６，９を介装した状態で前記壁面Ｗに夫々を取り付ける。
【００２１】
図示の例は、径違い継手部を保護するものであり、図４に示したように、前記第一スペーサ３と前記第三スペーサ９とは幅が異なり、前記第二スペーサ６は、図６に示すように、前記第一スペーサ３側と前記第三スペーサ９側とで幅が異なっている。つまり、図１に示したように、前記第一保護カバー１内に支持する配管の径は、前記第三保護カバー７内に支持する配管の径よりも大きく、従って、前記第一スペーサ３の幅は前記第三スペーサ９の幅よりも広いのである。前記位置決め突条１５は、幅の広い側、即ち、前記第一スペーサ３側に設け、前記位置決め突起１６を、幅の狭い側、即ち、前記第三スペーサ９の側に設けてある。前記位置決め突条１５は、前記係止部材２８の係合部２９の下方に形成された凹部２９ａの下端幅に合わせた長さに形成してあり、前記第一スペーサ３におけると同様に、前記係止部材２８の前記凹部２９ａに接当可能に位置させて形成されている。前記係止部材２８は、前記位置決め突起１６を下面に備える係止孔（図示省略）に係入させ、且つ、これら位置決め突条１５により位置ずれを規制した状態で、前記第二スペーサ６に貫通形成してあるネジ貫通孔１８に位置合わせして貫通してあるネジ孔２６にタッピングネジ等のネジを挿通して、前記第二スペーサ６と共に、前記係止部材２８が前記壁面Ｗに取り付けられるのである。
【００２２】
前記第二スペーサ６の裏面には、図７に示すように、周部に低い周壁１９を形成してあり、前記位置決め突起１６は、前記裏面に突出形成されたＬ字型の係止凸部２０に係合する位置に設けてある。尚、前記第二スペーサ６の表面に形成された位置決め突条１５の外側面も、その裏面に形成された前記周壁１９の内側面に位置を合わせてある。つまり、前記第二スペーサ６を重ねたときに、ずれなく重ねることが容易となるようにしてある。
【００２３】
前記第二カバー部材５の接続側端部である両端部は、図１に示したように、薄肉に形成し、外面をなだらかな曲面で形成し、前記第一カバー部材２又は前記第三カバー部材８との接続部に外面に形成される段差を極力小さくしてある。前記第二スペーサ６の側部輪郭は、前記第二カバー部材５の下端縁の外部輪郭と同形状に形成してあり、前記接当突起１２の内側対向面１２ａを、夫々接続する前記第一スペーサ３又は前記第三スペーサ９の両外側面との間に極力隙間を形成しないように形成してある。
【００２４】
以上のように構成した結果、接続する保護カバーのスペーサ同士の芯出しが容易になり、壁面上の罫書き線に沿って配置基準線を合わせた上で一方の例えば第一スペーサ３を仮固定し（図５（イ）参照）、これに第二スペーサ６を位置合わせすればよい（図５（ロ）参照）。上記例のように、第二保護カバー４の両側に保護カバーを配置する場合には、第三スペーサ９の配置基準線を前記壁面上の罫書き線に合わせて仮固定し、両スペーサ３，９の間に前記第二スペーサ６を介装することで、計画線上に長尺体を配置して保護することが容易となる。また、前記各スペーサを特定の厚さに形成しておいて、必要に応じて、所定の高さになるように重ねた状態で、前記各カバー部材と前記壁面との間に介装して取り付けることが容易となっている。
【００２５】
また、前記第二カバー部材５を、その接続側端部をなだらかに薄く形成して、前記第一カバー部材２に外嵌し、また、第三カバー部材８にも外嵌するようにして、前記第二スペーサ６の側部輪郭を前記第二カバー部材５の下端縁の外部輪郭と同形状に形成したから、接続部の保護性能を向上すると同時に、外観的にも美観に優れたものにできた。当然のことながら、各保護カバーの一端側と他端側とに、上述の第一保護カバーの接続側端部の構造と、上述の第二保護カバーの接続側端部の構造とを備えるようにすれば、各保護カバーを、その接続部に他の接続カバーを介装することなく接続することもできる。
【００２６】
〔別実施形態〕
上記実施の形態において示さなかった本発明に係る長尺体カバーの接続部の実施の形態について以下に説明する。
【００２７】
〈１〉上記実施の形態においては、直線カバーである第一保護カバー１に支持される配管と、直線カバーである第三保護カバー７に支持される配管の径が異なる径違い継手を保護する保護カバーとして、且つ、前記第一保護カバー１と前記第三保護カバー７とを接続する接続カバーとして形成した第二保護カバー４を図示して説明したが、前記第二保護カバー４は、上記径違い継手以外に、単なる管継手等の長尺体の径が増大している箇所を保護する接続カバーであってもよく、曲がり管継手等の長尺体の屈曲部を保護する接続カバーとして構成してもよい。この屈曲部の場合、第二スペーサは平面視屈曲形成してあり、前記第二スペーサの表面に罫書きされる配置基準線は、屈曲点の両側において所定角度に方位を異ならせて、前記屈曲点において交差させてあればよい。
【００２８】
〈２〉上記実施の形態においては、直線カバーである第一保護カバー１と第三保護カバー７とを、第二保護カバー４を接続カバーとして接続する例について説明したが、本発明に係る長尺体カバーの接続部は、前記第一保護カバー１と前記第二保護カバー４とを接続するだけの接続部であってもよい。例えば、前記第二保護カバー４が、配管の曲がり接続部において、壁面Ｗに沿う配管或いは電線等の長尺体に対して、接続される長尺体が、壁に穿たれた貫通孔内に配置される場合の保護カバー終端部を形成するものであってもよい。また、前記第二保護カバー４も直線配置された長尺体を保護する直線カバーとして構成してあってもよい。つまり、本発明に係る長尺体カバーの接続部を、単に直線カバー同士を接続する接続部として構成してもよいのである。
【００２９】
〈３〉上記〈２〉の代わりに、前記第二保護カバー４が、前記長尺体のＴ型分岐部を保護するものであってもよい。例えば、直線カバーである第一保護カバーと、第三保護カバーとが直線上に配置され、他の直線カバーである第四保護カバーがこれと直交する方向に配置された分岐部を保護する第二保護カバーとして構成され、両端に接続側端部を備え、且つ、その中間部から側方に延出してその先端に接続側端部を備えるように形成されていてもよい。この場合には、第二スペーサは、平面視Ｔ字状に形成され、各接続側端部に上記実施の形態における第二スペーサ６の接続側端部に形成された凹入部１０と同様に構成される凹入部を形成してあればよい。その第二スペーサに係止固定される第二カバー部材に関しても平面視Ｔ字状に形成する点は同様である。
【００３０】
〈４〉上記実施の形態においては、第一スペーサ３（若しくは第三スペーサ９）の裏面、即ち、それを取り付ける壁面Ｗ側の面に、平行で、且つ全長に亘る三条の溝２２を形成した例について説明したが、前記溝２２は、単一のものが全長に亘って形成されていてもよく、また、中央部に長さ方向に形成された縦リブを有するものであってもよい。さらに、前記溝２２は、接続側端部のみに形成されていてもよい。尚、これらスペーサに溝が形成されていなくてもよい。
【００３１】
〈５〉上記実施の形態における第二スペーサ６の凹入部１０に備える接当面１１に、例えば図８に示すように、前記第一スペーサ３の下方側、即ち前記壁面Ｗに接当する側に形成した溝２２の側壁に接当可能で、且つ、前記溝２２内に挿入自在な突出片部１３を、前記接当面１１に突出形成することもできる。図示の例においては、前記第一スペーサ３には、前記溝２２は平行に三条、夫々全長に亘って形成してあり、前記突出片部１３は、同図（イ）に示すように、前記第二スペーサ６の接続側端部の前記第一スペーサ３の溝２２内に位置する前記接当面１１の部位に、前記第一スペーサ３の両外側の溝２２における前記外側壁面２２ａに接当可能に一対形成し、前記第一スペーサ３を前記凹入部１０に相対嵌入することで、同図（ロ）に示すように、前記突出片部１３の外側面が前記外側壁面２２ａに接当し、前記凹入部１０に備える接当突起１２の芯出し機能を補完する。尚、前記第二スペーサ６に備える突出片部１３は、上記実施の形態に示したように、第一スペーサ３と第三スペーサ９との間に介装した場合に、前記第二スペーサ６を仮止めしなくても、前記第一スペーサ３と前記第三スペーサ９とに支持させた状態を維持できるから、そのまま係止部材２８を取り付けて、固定することも可能となる。また、前記突出片部１３を前記溝２２の深さにあわせてある場合には、前記第一スペーサ３（或いは第三スペーサ９）と前記壁面Ｗとの間に前記突出片部１３が狭持されるようになるから、前記突出片部１３を挿入するだけで、前記第二スペーサ６を仮固定することも可能である。尚、これら突出片部１３は、前記両外側の溝２２の内側壁面２２ｂ、即ち前記溝２２間のリブの側面に接当可能に形成してもよい。さらに、前記溝２２が単一形成されている場合には、前記突出片部１３も単一形成されていてもよい。この場合には、前記突出片部１３の幅を前記溝２２の幅に合わせてあることが好ましい。
【００３２】

[0026]
[Another embodiment]
Embodiments of the connecting portion of the long body cover according to the present invention not shown in the above embodiment will be described below.
[0027]
<1> In the above-described embodiment, the pipe joint supported by the first protective cover 1 that is a linear cover and the pipe joint supported by the third protective cover 7 that is a linear cover are protected from different diameter joints. The second protective cover 4 formed as a protective cover and as a connection cover for connecting the first protective cover 1 and the third protective cover 7 has been illustrated and described. In addition to the different diameter joint, it may be a connection cover that protects the location where the diameter of a long body such as a simple pipe joint has increased, or as a connection cover that protects a bent part of a long body such as a bent pipe joint. It may be configured. In the case of this bent portion, the second spacer is bent in plan view, and the arrangement reference line marked on the surface of the second spacer has a different angle at both sides of the bending point, and the bent portion is bent. It only needs to intersect at the point.
[0028]
<2> In the above embodiment, the example in which the first protective cover 1 and the third protective cover 7 that are linear covers are connected using the second protective cover 4 as a connection cover has been described. The connecting portion of the scale cover may be a connecting portion that only connects the first protective cover 1 and the second protective cover 4. For example, when the second protective cover 4 is connected to a long body such as a pipe or an electric wire along the wall surface W in the bent connection portion of the pipe, the long body to be connected is in a through hole formed in the wall. A protective cover terminal portion may be formed when arranged. Further, the second protective cover 4 may also be configured as a linear cover that protects the elongated body arranged in a straight line. That is, the connection part of the long body cover according to the present invention may be configured as a connection part that simply connects the linear covers.
[0029]
<3> Instead of the above <2>, the second protective cover 4 may protect the T-shaped branch portion of the elongated body. For example, a first protective cover that is a linear cover and a third protective cover are arranged on a straight line, and a fourth protective cover that is another linear cover protects a branch portion that is arranged in a direction orthogonal thereto. It may be configured as two protective covers, provided with connection-side end portions at both ends, and extended laterally from the intermediate portion thereof, and provided with a connection-side end portion at the tip thereof. In this case, the second spacer is formed in a T shape in plan view, and is configured in the same manner as the recessed portion 10 formed at the connection side end of the second spacer 6 in the above embodiment at each connection side end. What is necessary is just to form the recessed part to be formed. The second cover member locked and fixed to the second spacer is the same in that it is formed in a T shape in a plan view.
[0030]
<4> In the above-described embodiment, the three grooves 22 extending in parallel and over the entire length are formed on the back surface of the first spacer 3 (or the third spacer 9), that is, the surface on the wall surface W side to which the first spacer 3 is attached. Although the example was demonstrated, the said groove | channel 22 may be formed over the full length, and may have the vertical rib formed in the length direction in the center part. Further, the groove 22 may be formed only at the connection side end. In addition, the groove | channel does not need to be formed in these spacers.
[0031]
<5> On the contact surface 11 provided in the recessed portion 10 of the second spacer 6 in the above embodiment, on the lower side of the first spacer 3, that is, on the side contacting the wall surface W as shown in FIG. A protruding piece portion 13 that can be brought into contact with the side wall of the formed groove 22 and that can be inserted into the groove 22 can be formed to protrude from the contacting surface 11. In the illustrated example, the groove 22 is formed in the first spacer 3 over the entire length in parallel with each other, and the protruding piece 13 is formed as shown in FIG. It is possible to contact the outer wall surface 22a of the groove 22 on both outer sides of the first spacer 3 with the portion of the contact surface 11 located in the groove 22 of the first spacer 3 at the connection side end of the second spacer 6. The first spacer 3 is relatively fitted into the recessed portion 10 so that the outer surface of the protruding piece 13 contacts the outer wall surface 22a, as shown in FIG. The centering function of the contact protrusion 12 provided in the recessed portion 10 is supplemented. In addition, when the protrusion piece part 13 with which the said 2nd spacer 6 is equipped is interposed between the 1st spacer 3 and the 3rd spacer 9 as shown in the said embodiment, said 2nd spacer 6 is attached. Even if it is not temporarily fixed, since the state supported by the first spacer 3 and the third spacer 9 can be maintained, the locking member 28 can be attached and fixed as it is. Further, when the protruding piece 13 is adjusted to the depth of the groove 22, the protruding piece 13 is sandwiched between the first spacer 3 (or the third spacer 9) and the wall surface W. Therefore, the second spacer 6 can be temporarily fixed by simply inserting the protruding piece 13. In addition, you may form these protrusion piece parts 13 so that the inner side wall surface 22b of the said both outer side groove | channel 22, ie, the side surface of the rib between the said groove | channels 22, can contact | connect. Furthermore, when the groove 22 is formed as a single piece, the protruding piece 13 may be formed as a single piece. In this case, it is preferable that the width of the protruding piece 13 is matched to the width of the groove 22.

<6> In the above <5>, the example in which the pair of contact projections 12 and the pair of protruding pieces 13 are formed in the recessed portion 10 of the second spacer 6 has been described. In the case where the groove 22 is formed on the lower side in contact, instead of the projecting piece 13, for example, as shown in FIG. 9, the groove 22 can be inserted into the groove 22 and both side walls of the groove 22. A pair of holding projections 14 that can hold the portion 23 between the pair of contact projections 12 may be formed to protrude below the contact surface 11. In the example shown in the figure, as shown in FIG. 5A, the pair of sandwiching protrusions 14 can be pressed and contacted to the inner surface of the outer side wall 23 in the groove 22 inside the both sides of the first spacer 3. As shown in FIG. 5B, the contact projections are respectively formed on the side wall portions 23 from the outside by relatively fitting the first spacer 3 with the second spacer 6. 12 comes into surface contact, and the holding projection 14 is pressed from the inside. If the contact side portion 14a of the holding projection 14 is formed with irregularities to prevent the holding projection 14 and the side wall 23 from slipping in the arrangement reference line L direction, The relative holding member between the one spacer 3 and the second spacer 6 can be maintained well. The contact side portions 14a of the pair of sandwiching protrusions 14 are opposed to each other so that the ribs erected in the groove 22 are sandwiched between the contact side portions 14a on both sides. Also good.

<7> The above describes the example in which both the connection side end portions of the protective cover have the same configuration and the second protective cover 4 is the connection cover. It is good also as a structure of the connection side edge part in a protective cover, and making the other connection side edge part into a structure of the connection side edge part in said 2nd protection cover. If comprised in this way, protection covers can be easily and easily connected between one end side and the other end side, and a protective function for an internal long body without using another connection cover or connection member at the connection portion. Can be granted.
