Description

【０００１】
【発明の属する技術分野】
本発明は、コンセント等の配線器具等の取付構造に関するものである。
【０００２】
【従来の技術】
従来より、壁材にコンセント等の配線器具を取付ける構造としては種々のものが提案されているが、その中でも、特開平６ー２２５４２６号公報にて提案されているものがあり、具体的には、図５及び図６に示すような構造となっている。
【０００３】
即ち、取付枠１０３の裏面に支持部材１０４が突設するように支持されており、これを円穿孔１１０内に収納配置し、支持部材１０４の先部に設けられた当接片１０５を円穿孔１１０の裏面側開口縁１０５に当接させ、この状態でボックスねじ１０２を取付枠１０３の上部に形成された通孔１０３ａと支持部材１０４の下端部に形成されたねじ孔に締め込むことによって取付枠１０３と当接片１０５とで壁板１０１を挟持して円穿孔１１０に取付けられるようになっている。
【０００４】
【発明が解決しようとする課題】
しかしながら、上述のような従来の配線器具等の取付構造を使用して、壁材１０１に穿設された一の円穿孔又は複数の重合からなる円穿孔１１０に取付ける場合に、ボックスねじ１０２は支持部材１０４の下端部に形成されたねじ孔に螺合されるので、支持部材１０４の下端部が取付枠１０３方向に引き寄せられて締付け固定される。従って、壁板１０１を挟持する取付枠１０３と当接片１０５との挟持力は弱くなってしまい、確実な挟持を行なうことができないという問題があった。
また、壁板１０１を挟持する取付枠１０３と当接片１０５との挟持力を強くするために、ボックスねじ１０２の強い締付けを要し、支持部材１０４を変形させる虞があるという問題があった。
【０００５】
本発明は、上記の事情に鑑みてなされたもので、その解決すべき課題は、上述した従来の点字板が具備する問題点を解決することであり、その目的は、壁材の挟持を確実に強固に行なうことができる配線器具等の取付構造及び挟持具を提供することである。
【０００６】
【課題を解決するための手段】
以上を解決するために、本発明の採った手段は、実施形態において使用する符号を付して説明すると、まず請求項１に係る発明の配線器具等の取付構造は、壁材１に形成された一の円穿孔又は複数の円穿孔の重合からなる取付孔１０の壁表周縁に当接する器具取付枠２０と、前記取付孔の壁裏周縁に当接する挟持具３０とで壁材を挟持する配線器具等の取付構造１００を前提とするものであって、前記挟持具３０は、前記壁材１に貼着可能な当接部を備えるとともに、その左右両端部３１が取付孔周端部１１に交差する位置より上方の略中央部で、器具取付枠２０に貫通された締付ねじ４０が螺合されてなり、前記締付ねじ４０の締付によって、器具取付枠２０と挟持具３０により壁材１を挟持することをその要旨としている。
【０００７】
次に、請求項２に係る発明の挟持具３０は、壁材１に形成された一の円穿孔又は複数の円穿孔の重合からなる取付孔１０の壁表周縁に当接する器具取付枠２０を、前記壁材１に固定する挟持具３０を前提とするものであって、前記取付孔１０の壁裏周縁に当接し、前記壁材１に貼着可能な当接部を備えるとともに、前記壁裏周縁に配置した際に、その左右両端部３１が取付孔周端部１１に交差する位置より上方の略中央部で、器具取付枠２０に貫通された締付ねじ４０が螺合し、前記締付ねじ４０の締付によって前記器具取付枠２０とにより壁材１を挟持することをその要旨としている。
【０００８】
最後に、請求項３に係る発明の挟持具３０は、壁材１に形成された一の円穿孔又は複数の円穿孔の重合からなる取付孔１０の壁表周縁に当接する器具取付枠２０を、前記壁材１に固定する挟持具３０を前提とするものであって、前記取付孔１０の壁裏周縁に当接し、前記壁材１に貼着可能な当接部と、前記壁裏周縁に配置した際に、その左右両端部３１が取付孔周端部１１に交差する位置より上方の略中央部で、器具取付枠２０に貫通された締付ねじ４０が螺合すべく、前記取付孔１０の切口端に当接するガイド部３３とを備えたことをその要旨としている。
【０００９】
図１又は図２に示すように、配線器具等の取付構造１００は、矩形状に形成された器具取付枠２０と板状に形成された挟持具３０と、締付ねじ４０とから構成されている。
【００１０】
そして、ベニヤ板、石膏ボート等で形成されている壁材１には、一部を二つの円穿孔が重合するように切り欠くことによって形成された取付孔１０が設けられており、この取付孔１０に器具取付枠２０が取付けられるようになっている。取付孔１０は、取付けられる配線器具等のサイズに応じて、一つの円穿孔又は複数の円穿孔が重合されて形成されたものでもよい。
【００１１】
前記器具取付枠２０は、合成樹脂等で一体形成されており、壁材１に形成された取付孔１０の壁表周縁に配置できるように矩形状に形成されたものである。器具取付枠２０には平面部２２が形成され、該平面部の上部と下部の略中央には締付ねじ４０が挿通される挿通孔２１が各々設けられており、挿通孔２１の上部には器具取付枠２０を覆うように器具取付枠２０の外面側に設置される化粧カバーを固定するための固定ネジ（図示せず）が挿入されるネジ孔２６が形成されている。
【００１２】
図１に示すように、平面部２２の中央部には、コンセント、スイッチ等の配線器具５０が挿入され配線器具５０の前面部が壁の表側に臨ませるように四角形状に開口部２３が形成されている。そして、器具取付枠２０の裏面側には開口部２３の全周に至って裏側に向かって突出する板状の枠体２４が一体に形成されている。枠体２４の左右片部には配線器具５０の係止突起部を係止して取り付けるための保持部２５が設けられている。
【００１３】
次に、挟持具３０は、図１又は図３に示すように、合成樹脂等で板状に形成されたものである。そして、取付孔１０の壁裏周縁に当接する部分には、請求項に当接部として記載の貼着部３４が形成されている。この貼着部３４は、両面粘着テープが貼着されている構成となっている。この貼着部３４により壁体１の壁裏に仮固定することが可能となるので後述する器具取付枠２０等の取付けが容易となるのである。尚、貼着部３４は両面テープを貼着した構成に限定されることなく、例えば、壁材１に突き刺すことによって仮固定が可能な突起体を当接部３４に設けたものでもよく、仮固定が可能な構成であればどんな構成のものでもよい。また、挟持具３０の略中央部には締付ねじ４０が螺着される螺着孔３２が形成され、その螺着孔３２の両側にはガイド部３３が各々設けられている。
【００１４】
前記ガイド部３３は、挟持具３０を壁裏周縁に配置させるときに、取付孔１０の壁材切口端に当接させることにより、挟持具３０を所定位置に配置させる役割をするものである。つまり所定位置とは、図３に示すように、挟持具３０に形成された貼着部３４を取付孔１０の壁裏周縁に当接させ且つ各々のガイド部３３を取付孔１０の壁材切口端に当接するように配置した際に、螺着孔３２が挟持具３０の左右両端部３１が取付孔１０の取付孔周端部１１に交差する位置より上方の略中央になるように配置される位置である。これにより、左右両端部３１が取付孔周端部１１に当接するため、図４に示すように、締付ねじ４０を器具取付枠２０に形成された挿通孔２１に挿通させ且つ螺着孔３２に螺合させて締め込めば、器具取付枠２０は挟持具３０方向に略平行に引き寄せられる。その結果、貼着部３４の全体と器具取付枠２０とによって壁材１の挟持を確実に強固に行なうことが可能となる。
また、挟持具３０の上下両端部の長さ（ａ）は、取付孔１０を形成する円穿孔の口径（ｂ）よりも短いため、取付孔１０の壁裏に容易に挿入させて配置することができる。
【００１５】
尚、ガイド部３３は実施例に示したものに限定することはなく、例えば、取付孔１０の壁材切口端に沿うように当接する円弧形状の壁材等を立設させたものでもよく、壁材切口端に当接することにより螺着孔３２が所定位置に配置されるものであればどんなものでもよい。
【００１６】
次に、器具取付枠２０、挟持具３０及び締付ねじ４０とから構成される配線器具等の取付構造１００の取付けについて説明する。
【００１７】
図１、図３又は図４示すように、壁材１に形成された取付孔１０の上下壁裏周縁に各々の挟持具３０を挿入する。そして、各々のガイド部３３を取付孔１０の壁材切口端に当接させると共に、貼着部３４を取付孔１０の壁裏周縁に貼着させて仮固定をする。このとき螺着孔３２は、上述したように、挟持具３０の左右両端部が取付孔１０の取付孔周端部１１に交差する位置より上方の略中央に位置している。そして、器具取付枠２０を取付孔１０の壁表周縁に当接するように配置させる。
【００１８】
次に、図４に示すように、締付ねじ４０を器具取付枠２０に形成された挿通孔２１に挿通させ且つ螺着孔３２に螺合させて締め付ければ器具取付枠２０は挟持具３０に対して略平行に引き寄せられる。従って、貼着部３４の全体と器具取付枠２０とによって壁材１の挟持を確実に強固に行なうことができる。
【００１９】
【発明の効果】
以上詳述した通り、本願請求項１記載に係る発明の配線器具等の取付構造においては、壁材に形成された一の円穿孔又は複数の円穿孔の重合からなる取付孔の壁表周縁に当接する器具取付枠と、前記取付孔の壁裏周縁に当設する挟持具とで壁材を挟持する配線器具等の取付構造であって、前記挟持具は、前記壁材に貼着可能な当接部を備えるとともに、その左右両端部が取付孔周端部に交差する位置より上方の略中央部で、器具取付枠に貫通された締付ねじが螺合され、前記締付ねじの締付けによって、器具取付枠と挟持具とにより壁材を挟持する構成となっている。
【００２０】
従って、締付ねじの締付けにより器具取付枠が挟持具方向に略平行に引き寄せられるため、貼着部の全体と器具取付枠とによって壁材の挟持を確実に強固に行なうことができるという優れた効果を奏するものである。さらに、壁体の壁裏に容易に仮固定することができるため、器具取付枠等の取付けを容易に行なうことができるという優れた効果を奏するものである。
【００２１】
次に、請求項２記載に係る発明の挟持具においては、壁材に形成された一の円穿孔又は複数の円穿孔の重合からなる取付孔の壁表周縁に当接する器具取付枠を
、前記壁材に固定する挟持具であって、前記取付孔の壁裏周縁に当接し、前記壁材に貼着可能な当接部を備えるとともに、前記壁裏周縁に配置した際に、その左右両端部が取付孔周端部に交差する位置より上方の略中央部で、器具取付枠に貫通された締付ねじが螺合し、前記締付ねじの締付によって前記器具取付枠とにより壁材を挟持する構成となっている。
【００２３】
従って、請求項１と同様に、締付ねじを器具取付枠に形成された挿通孔に挿通させ且つ螺着孔に螺合させて締め込めば、器具取付枠は挟持具方向に略平行に引き寄せられるため、当接部の全体と器具取付枠とによって壁材の挟持を確実に強固に行なうことができるという優れた効果を奏するものである。さらに、壁体の壁裏に容易に仮固定することができるため、器具取付枠等の取付けを容易に行なうことができるという優れた効果を奏する。
【００２４】
最後に、請求項３記載に係る発明の挟持具は、請求項２記載の挟持具に、取付孔の切口端に当接するガイド部を備えたことにより、請求項２記載の発明と同様な目的を達成することができる他、さらに、挟持具に形成された当接部を取付孔の壁裏周縁に当接させ且つ各々のガイド部を取付孔の壁材切口端に当接するように配置させるのみで、容易に螺着孔が挟持具の左右両端部が取付孔の取付孔周端部に交差する位置より上方の略中央になるように配置することができる。
