【発明の属する技術分野】
本発明は、建物の内装壁の裏側に配置された柱等の造営材又は奥壁に固着することで、内装壁に設けられる壁開口に配設する配線器具取付部材に関するものである。
【０００２】
【従来の技術】
従来より、内装壁裏側の可撓電線管内の電線が接続される配線器具を壁開口に配設するには、配線器具取付部材としてスイッチボックスを上記壁開口に配設し、このスイッチボックスに上記配線器具を取り付ける方法が採られていた。
【０００３】
スイッチボックスは、前面（室内側の面）が開口した大略箱状の部材であって上記可撓電線管の接続も可能であり、内装壁表側（室内側）からは、配線器具保持プレートを介して壁スイッチや壁コンセント等の配線器具を取り付けることが可能となっている。
【０００４】
しかし、このようなスイッチボックスにあっては、前面が開口した大略箱状をしているため、配線器具に結線したりする作業が内装壁表側からしかできないものであり、また、可撓電線管を接続する際には別体の接続部品が必要となるものであり、さらに、配線器具等を良好に収容できるようにスイッチボックスの奥行き長さを長くしているため、内装壁裏側の隙間の奥行きが狭い場合にはスイッチボックスを配設できないものであった。
【０００５】
そこで、本願出願人は図５，図６に示すような配線器具取付部材を提案した。これは、図５に示すように、建物の内装壁Ａに設けられる壁開口Ａ１の裏側近傍に配設されてある柱等の造営材Ｂに配線器具取付部材２’を固着具Ｆで取り付け、内装壁Ａ裏側に配設されてある可撓電線管Ｄの端部を配線器具取付部材２’にて保持し、可撓電線管Ｄ内を挿通する電線（図示せず）を配線器具Ｃに接続して、配線器具取付部材２’に形成された開口３１’に配線器具Ｃを取り付けるものである。配線器具取付部材２’は、図６に示すように、内部に配線器具Ｃを配設するための開口３１’を形成した本体枠部３’にて主体が構成され、配線器具Ｃを取り付けるための配線器具取着部３２’を本体枠部３’の開口３１’縁の上下二箇所に設けると共に、本体枠部３’を上記造営材Ｂに固着するための造営材固着部４’を本体枠部３’の両側部に設けてある。造営材固着部４’には固着具Ｆが挿通される固着具挿通孔４２’が穿孔されており、柱等の造営材Ｂの側面のうち内装壁Ａに垂直な側面Ｂ１に造営材固着部４’を当接させて、開口３１’側より固着具Ｆを固着具挿通孔４２’に挿入して上記側面Ｂ１に螺着することで本体枠部３’を造営材Ｂに固着する。このようにして、本体枠部３’が内装壁Ａに設けられる壁開口Ａ１縁に沿うように配線器具取付部材２’を壁開口Ａ１に配設するものである。なお、図中のＥは、内装壁Ａの表側より壁開口Ａ１に配設される化粧プレートを示す。
【０００６】
しかし、このような配線器具取付部材２’にあっては、内装壁Ａに設ける壁開口Ａ１裏側近傍に柱等の造営材Ｂが配設されていなかったりした場合、特に、コンクリート製の奥壁の表側に隙間を介して石膏ボードで形成した内装壁を配置する所謂ＧＬ工法のように、内装壁Ａ裏側に柱等の造営材Ｂが存在しないといった場合には、壁開口Ａ１縁に沿うように本体枠部３’を固着することができず、壁開口Ａ１に配線器具取付部材２’を配設することができないという問題があった。
【０００７】
【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、その目的とするところは、内装壁に設ける壁開口裏側近傍に柱等の造営材が配設されていなかったりした場合でも、壁開口縁に沿うように本体枠部を固着して壁開口に配設可能な配線器具取付部材を提供することを課題とするものである。
【０００８】
【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線器具取付部材は、内装壁の裏側に配置された柱等の造営材又は奥壁１に固着して内装壁に設けられる壁開口に配設する配線器具取付部材２であって、配線器具が配設される開口３１を内部に形成し枠状をした本体枠部３で主体が構成され、本体枠部３に該本体枠部３に形成した開口３１に配設される配線器具を取着する配線器具取着部３２を設け、本体枠部３の側部に上記造営材の側面に固着することで本体枠部３を上記壁開口縁に沿って配設可能とする造営材固着部４を設け、本体枠部３の少なくとも一側部に上記奥壁１の表側面に固着することで本体枠部３を上記壁開口縁に沿って配設可能とする奥壁固着部５を設け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、本体枠部３を内装壁の裏側に配設されてある柱等の造営材の側面に固着して配線器具取付部材２を壁開口に配設することができるうえに、内装壁の裏側に配設されてある奥壁１の表側面にでも本体枠部３を固着して配線器具取付部材２を壁開口に配設することが可能となる。
【０００９】
また、奥壁固着部５を本体枠部３に対して着脱自在とすることが好ましい。このような構成とすることで、本体枠部３を奥壁１の表側面に固着する際に本体枠部３に奥壁固着部５を取り付けたり、本体枠部３を柱等の造営材の側面に固着する際に不要となる奥壁固着部５を取り外したりすることが可能となる。
【００１０】
また、奥壁固着部５を、奥壁１の表側面に当接すると共に固着具５１にて奥壁１の表側面に固着されるための固着具通孔５２が穿孔された当接部５３と、当接部５３より連設されて本体枠部３に係止される係止部５４とで構成し、本体枠部３に奥壁固着部５の係止部５４が係止可能な被係止部３５を設けることが好ましい。このような構成とすることで、本体枠部３に形成された開口３１内側から又は本体枠部３の外側からの何れ側からでも奥壁固着部５を取り付け自在とすることが可能となって、本体枠部３を奥壁１の表側面に固着する場合に、本体枠部３の外側に奥壁固着部５を取り付けることで本体枠部３の開口３１の背面側に背面カバーを取り付けること可能となったり、何らかの障害物が存在して奥壁固着部５を本体枠部３の外側に取り付けると奥壁１の表側面に本体枠部３を取り付けられなくなる時に、奥壁固着部５を本体枠部３の開口３１内側に取り付けることで本体枠部３を奥壁１の表側面に取り付けることが可能になったりするものであり、さらに、一種類の奥壁固着部５を複数種類の配線器具取付部材２に対応させることが可能となって、新たな配線器具取付部材２の設計・製造コストを低く抑えることができるようになる。
【００１１】
【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。
【００１２】
本発明における配線器具取付部材２は、建物の内装壁に設けられる壁開口に配設して、この配線器具取付部材２に配線器具を取り付けると共に、該配線器具に内装壁の裏側に配設されてある可撓電線管内の電線を接続するものである。
【００１３】
建物の内装壁は、一定厚さの石膏ボードで形成された板状の壁材で、室内に面するものであり、該内装壁の裏側（すなわち室内と反対側）には、建物の造営材であって該内装壁が取り付けられる柱が配置されてあると共に、更に柱の裏側にコンクリート製の奥壁１が配置されてある。
【００１４】
奥壁１は、平面状の表側面を有するコンクリート製の壁材で、その表側（すなわち室内側）には柱が複数配置されてある。柱はそれぞれ水平断面略矩形をしており、複数の柱の表側面は、奥壁１の表側面と平行な同一平面上に位置するように配置されてある。そして、複数の柱の表側面に上記内装壁を取り付けてあり、さらに、内装壁と奥壁１との間に形成される隙間には、電線が内部に挿通された可撓電線管が配設されてある。
【００１５】
内装壁には、内装壁の表側と裏側とを連通する、前面視（すなわち内装壁の表側から裏側に向かう方向に見て）で上下方向に長い略矩形の壁開口が設けられるもので、この壁開口に対応する奥壁１の表側面に配線器具取付部材２を固着するものである。
【００１６】
配線器具取付部材２は、前面視で略矩形の枠状をした本体枠部３で主体が構成される。本体枠部３は、前面視で外形が内装壁に設ける壁開口縁とほぼ同形同大の略矩形の枠状のもので、内部には配線器具が配設される前面視略矩形の開口３１が形成されると共に、該開口３１縁には配線器具を本体枠部３に取着するための配線器具取着部３２が設けてある。
【００１７】
配線器具取着部３２は、本体枠部３内に形成された開口３１縁の上辺及び下辺の中央に、前後方向に長い略円筒状のものとして開口３１内に向けてそれぞれ突設してあり、配線器具取着部３２の内部には、配線器具を取着する固着具５１が螺入される螺入孔３２ａが表側より穿孔してある。
【００１８】
また、本体枠部３には、本体枠部３の上横片及び下横片の一側端部に、可撓電線管を保持する管保持部３３が設けてある。管保持部３３は、平面視で背方に開口した略Ｕ字形の半筒状のもので、本体枠部３の上横片の一側端部より上方に向けて突設すると共に、下横片の同側端部より下方に向けて突設してある。この管保持部３３は、内装壁の裏側に配設されてある可撓電線管を本体枠部３に保持するため、可撓電線管が管保持部３３の略Ｕ字形の開口３３ａ内に嵌め込まれるものである。
【００１９】
また、本体枠部３の両側部には、内装壁の裏側に配設されてある柱に固着する造営材固着部４が設けてある。造営材固着部４には、前記柱の側面のうち内装壁に垂直な側面に当接する造営材当接部４１が形成してあると共に、造営材当接部４１には、前後方向に長い固着具挿通孔４２が穿孔してある。
【００２０】
造営材当接部４１は、本体枠部３の両側部外面の上下方向三箇所にそれぞれ前後方向に長い凸部として形成してあり、凸部の突出面が造営材である柱の側面に当接する造営材当接面４３となっている。このように造営材当接部４１を本体枠部３に設けることで、造営材当接部４１を内装壁の裏側に配設されてある柱の側面のうち内装壁に垂直な側面に当接させて固着した際に、本体枠部３を内装壁の壁開口縁に沿うように配設することが可能となり、更に、本体枠部３の両側部に造営材当接部４１を設けることで、柱が内装壁に設ける壁開口裏側の左右いずれ側に位置する場合であっても、上記のように造営材当接部４１を柱の側面に当接して固着することが可能となる。そして、造営材当接部４１には、本体枠部３内に形成された開口３１内と造営材当接面４３の外方とを連通する前後方向に長い固着具挿通孔４２が穿孔してある。本体枠部３の柱への固着は、本体枠部３に設けた造営材当接部４１の造営材当接面４３を上記柱の側面に当接させ、固着具５１を本体枠部３内に形成された開口３１側より固着具挿通孔４２に挿入して柱の側面に螺着することで行うが、固着具挿通孔４２を前後方向に長く設けてあるため、固着具挿通孔４２内の前後方向の任意位置に固着具５１を挿入して柱に螺着することが可能となっている。
【００２１】
また、本体枠部３の両側部には、内装壁裏側の奥壁１に固着する奥壁固着部５を着脱自在に設けるものである。奥壁固着部５は、奥壁１の表側面に当接する当接部５３と、当接部５３より突設されて本体枠部３の造営材固着部４の固着具挿通孔４２に係止される係止部５４とからなる。
【００２２】
当接部５３は、前面視大略矩形でその背面が奥壁１の表側面に当接する当接面５５となっており、前面視でほぼ中央部には、円形の固着具通孔５２が穿孔してある。当接部５３の本体枠部３側には、本体枠部３に係止される係止部５４が突設してある。係止部５４は、平面視で背方に開口する大略コ字形をしており、奥壁固着部５を本体枠部３に係止する際、係止部５４の先端５４ａを本体枠部３の造営材固着部４の固着具挿通孔４２に挿入して、固着具挿通孔４２の後方側端部に大略コ字状の係止部５４の開口内奥部５４ｂを嵌め込むものである。すなわち、本実施形態においては、奥壁固着部５の係止部５４が係止される本体枠部３側の被係止部３５を、本体枠部３を造営材に固着するための固着具挿通孔４２と兼用するものであり、このようにすることで、本体枠部３の製造工程等を簡略化することができる。そして、奥壁固着部５を本体枠部３に係止する際、奥壁固着部５の係止部５４は、本体枠部３の開口３１内側から又は本体枠部３の造営材当接面４３の外側からの何れ側からでも本体枠部３の固着具挿通孔４２に挿入して係止することが可能となっている。このようにすることで、本体枠部３を奥壁１の表側面に固着するにあたって、本体枠部３の開口３１の背面側に配線器具に接続された電線等が奥壁１に接触するのを防止する背面カバー（図示せず）を取り付けたりする場合には、奥壁固着部５を本体枠部３の外側に取り付ればよく、また、何らかの障害物が存在して奥壁固着部５を本体枠部３の外側に取り付けると奥壁１の表側面に本体枠部３を取り付けられなくなる場合には、奥壁固着部５を本体枠部３の開口３１内側に取り付けることで本体枠部３を奥壁１の表側面に取り付けることが可能になったりするものである。また、上記のように係止部５４を本体枠部３の固着具挿通孔４２に係止して奥壁固着部５を本体枠部３に取り付けた時、奥壁固着部５の当接面５５は本体枠部３の背面とほぼ同一平面となるように当接部５３を成形してあるため、奥壁固着部５を本体枠部３に取り付けて奥壁１の表側面に当接させた状態で、当接部５３に穿孔した固着具通孔５２に固着具５１を挿入して奥壁１の表側面に螺着することで、本体枠部３を奥壁１の表側面に固着することができる。
【００２３】
以上ような構成の配線器具取付部材２を内装壁の壁開口に配設するには、内装壁の裏側に配設された柱等の造営材の側面に本体枠部３を固着するか、あるいは、内装壁の裏側に配設された奥壁１の表側面に本体枠部３を固着するかの二通りの方法があり、前者は図５に示すように従来例と同様の方法であるため、後者について以下に説明する。
【００２４】
配線器具取付部材２の本体枠部３を内装壁の裏側に配設された奥壁１の表側面に固着するには、まず、二個の奥壁固着部５を本体枠部３の両側部に取り付ける。これは上述した通り、奥壁固着部５に突設されてある係止部５４の先端５４ａを本体枠部３の造営材固着部４の固着具挿通孔４２に挿通して、大略コ字状の係止部５４の開口内奥部５４ｂを固着具挿通孔４２の背方側端部に当接するように嵌め込むものである。なお、本体枠部３に取り付ける奥壁固着部５は二個に限定されるものではなく、一個でもよい。次に、奥壁固着部５を取り付けた本体枠部３を内装壁の壁開口に対応する奥壁１の表側面に当接させる。そして、奥壁固着部５の固着具通孔５２に固着具５１を表側より挿入して奥壁１の表側面に螺着し、奥壁固着部５を奥壁１の表側面に固着する。その後、可撓電線管の端部を本体枠部３の管保持部３３に保持して可撓電線管を配設したり、配線器具を配線器具取付部材２に取り付けたり、可撓電線管内の電線を配線器具に接続するといった作業を行うものである。
【００２５】
かかる構成によれば、配線器具取付部材２を内装壁に設けられる壁開口に配設するにあたって、奥壁固着部５を本体枠部３に着脱自在に取り付けて、奥壁固着部５を奥壁１の表側面に固着具５１にて固着することで本体枠部３を奥壁１に固着可能となって、配線器具取付部材２を配設する内装壁の壁開口裏側近傍に柱等の造営材が配設されていない場合でも、本体枠部３が壁開口縁に沿うように配線器具取付部材２を壁開口に配設可能となるものである。特に、コンクリート製の奥壁１の表側に隙間を介して石膏ボードで形成した内装壁を配置する所謂ＧＬ工法のように、内装壁裏側に柱等の造営材が存在しない場合でも、本体枠部３が壁開口縁に沿うように配線器具取付部材２を壁開口に配設可能となる。また、本体枠部３を壁開口裏側の柱等の造営材の側面に固着する場合には、奥壁固着部５が本体枠部３より外方に向けて突出して邪魔にならないように、奥壁固着部５を取り外しておくことで本体枠部３の造営材固着部４を柱等の造営材の側面に固着することができる。さらに、従来の配線器具取付部材２’に着脱自在な奥壁固着部５を取り付けるたけで本発明の配線器具取付部材２とすることもできるため、この場合には配線器具取付部材２の新たな設計・製造は着脱自在とした奥壁固着部５についてのみ行えばよく、また、配線器具一個取着用，配線器具二個取着用，配線器具三個取着用といった複数種類の配線器具取付部材２に同一の奥壁固着部５を対応させることも可能となって、新たな配線器具取付部材２の設計・製造コストを低く抑えることができる。さらに、奥壁固着部５は本体枠部３の開口３１内側から又は本体枠部３の造営材当接面４３の外側からの何れ側からでも本体枠部３に取り付け可能となっており、奥壁固着部５を本体枠部３の外方に取り付けることで、背面カバーを本体枠部３の開口３１の背面側に取り付けたりすることができる。
【００２６】
次に他の実施形態について図４に基づいて説明する。本実施形態も上実施形態と基本的に同じであり、主に異なる点について述べる。本実施形態の場合は、奥壁固着部５を、本体枠部３に形成された開口３１内の四隅に本体枠部３に一体的に設けるものである。
【００２７】
本実施形態の奥壁固着部５は、前面視略正方形の当接部５３が本体枠部３の開口３１内の四隅に開口３１内に向けて一体的に突設してある。当接部５３には、上実施形態と同様に奥壁固着部５を奥壁１の表側面に固着するための固着具通孔５２が設けてあるが、奥壁固着部５は本体枠部３に一体的に設けてあるため不要となる係止部５４は設けていない。本実施形態における当接部５３は、上実施形態における奥壁固着部５よりも小さいため、本体枠部３の開口３１内に向けて突設してあっても該開口３１内を広く使用することができる。
【００２８】
また、当接部５３は、本体枠部３の外側に向けて本体枠部３に一体的に突設してもよく、この場合には、本体枠部３の開口３１の背面側に背面カバーを取り付けることも可能となる。
【００２９】
