【発明の属する技術分野】
本発明は、サポートおよび配線器具に関する。
【従来の技術】
従来、スイッチやコンセント等のような配線器具は、配線器具を取付枠であるサポートに取り付け、営造物である壁面に埋め込まれた配線ボックスから引き出された配線を接続器具に接続した上でサポートを配線ボックスにねじ止めし、配線器具の作用部を露出させた状態で取付枠等を覆う化粧プレートを取り付けることで壁面に設置されている。なお、配線器具の「作用部」というのは、その配線器具の作用を奏する部分を意味し、例えば、スイッチの場合であればスイッチ操作部、コンセントの場合であればプラグ挿入部が「作用部」に該当する。
【０００２】
このような従来技術として、出願人は、特開２０００−２８７３２８号公報に記載の発明を開示している。
【０００３】
この従来技術は、配線器具が一面から他面に向かって挿入される開口部を設けた枠部と、枠部の一側に設けられ、配線器具の一側を係止する固定係止部と、枠部の他側に設けられた取付受部と、取付受部に取り付けられ、配線器具の他側を係止する弾性変形可能な可動係止部を設けた係止体とを具備したサポートであり、これにより配線器具の一側を固定係止部に係止し、配線器具の他側を係止体の可動係止部を弾性変形させて係止することにより、配線器具がサポートに工具を用いずに取り付けられ、配線器具を取り付ける作業性が良好になるというものである。
【発明が解決しようとする課題】
しかしながら従来技術は、サポートを営造物である壁面に埋め込まれた配線ボックスへ取着するために、サポートの開口部の上下方向にそれぞれ一個所ずつ形成されている壁面取付用ねじ孔へ壁面取付用ねじを挿入し、配線ボックスへ形成されたサポート取付用ねじ孔へ壁面取付用ねじを螺合させているが、壁面取付用ねじ孔が設けられているサポート部分が平板状であるので、壁面取付用ねじを螺合する際に生じる配線ボックス側へのサポートの撓み力に対して抗ずることができずサポートを撓ませるということがまれにあった。
【０００４】
このようにサポートが撓んでしまうと、サポートへ取付けるアダプタ等にも撓みが生じてしまい、壁面とアダプタ等との間に隙間を生じさせてしまうので、外観上好ましいものではなかった。
【０００５】
本発明は上記に鑑みなされたものであり、サポートを壁面等に取付ける際のサポートの撓みを防ぐとともに、サポートに取付けるアダプタ、化粧プレート等にも撓みを生じさせずに壁面へ取付けた際に生じる不具合を防止するサポート及び配線器具を提供することを目的とする。
【課題を解決するための手段】
請求項１記載の配線器具は、配線器具本体と；複数の配線器具本体が一面から他面に向かって挿入して配置することができる開口部と、この開口部の長手向において開口部を挟んで対向する一対の器具支持部とを設け、開口部に挿入させた配線器具本体を一対の器具支持部で支持する枠部と、枠部の一方の器具支持部側に設けられ、配線器具本体の一側と係合する係合係止部と、枠部の他方の器具支持部側に設けられ、配線器具本体の他側を係止する可動係止部と、一方の器具支持部側よりも枠部の長手方向に延出された枠部の長手方向から見て開口部よりも他面側に突出する断面コの字状に形成された第１補強枠部と、一面側及び他面側から見てコ字状に形成される切欠きを介して前記第１補強枠部から延出された枠部の長手方向から見て開口部よりも他面側に突出する断面コの字状に形成された第２補強枠部と、他方の器具支持部側よりも枠部の長手方向に延出された枠部の長手方向から見て開口部よりも他面側に突出する断面コの字状に形成された第３補強枠部と、他方の器具支持部側であって、前記切欠きと対向する位置には枠部の長手方向から見て開口部よりも他面側に突出し、かつ他面側から見て他方の器具支持部よりも外側に突出する突出片を備える断面コの字状に形成された第４補強枠部と、対向する補強枠部間に形成されたアダプタ取付用ねじ孔と、アダプタ取付用ねじ孔よりも開口部側に形成された壁面取付用ねじ孔とを具備するサポートと；両端部、この両端部の内側にサポートの開口部と対向するように窓部が設けられるとともに、サポートに設けられたアダプタ取付用ねじ孔に螺合するアダプタ取付用ねじが挿入されるねじ挿入孔が形成された取付部を上下２箇所に設けており、両端部と各取付け部との間には補強枠部が当接しないように補強枠部除け部が設けられたアダプタと；アダプタに取付けられる化粧プレートと；を具備することを特徴とする。
【０００６】
サポートは、例えば、一枚の板金にプレス加工、押し抜き加工、曲げ加工等を施すことによって形成される。その材料としては、例えば、亜鉛クロマイトメッキを施した鉄（ＳＰＣＣ）等が用いられるがこれに限定されるわけではない。
【０００７】
係合係止部は、枠部と一体で形成することが可能であるがこれに限定されるわけではない。
【０００８】
可動係止部は、例えば、弾性を有する金属片等によって形成される。その材料として好ましくは、例えば、厚さ０．３ｍｍ程度のステンレス（ＳＵＳ）等が用いられるがこのようなものに限定されるわけではない。
【００１８】
配線器具本体は、作用部が一体で形成されているものであってもよいし、別体で形成されているものでもよい。別体で形成されているものは、例えばワイドハンドル形のスイッチ装置等であり、この場合はプレートの開口部を閉塞するようにワイドハンドル部である操作部が配線器具本体に取付けられる。
【００１９】
請求項１の発明によれば、サポートを壁面へ取付ける際にサポートに撓みを生じさせないことに加えて、アダプタをサポートへ取付ける際にまれに生じる壁面取付手段へ作用するアダプタの撓み力が両端部へ伝わらないので、アダプタ自体が撓むことを防ぐことができ、壁面とアダプタ等との間に隙間を生じさせることをより防ぎことができる、したがって、外観上も更に確実に良好なものとすることができる。

また、配線器具本体１２は、カバー１５から突出し、かつ、揺動自在に支持されたハンドル１３を備えており、このハンドル１３には金属製のハンドル受け１３aが取付けられている。
【００２８】
サポート１は、取付枠とも呼ばれるもので、図１ないし図４に示すように、亜鉛クロマイトメッキを施した鉄（ＳＰＣＣ）などの金属製の枠状をなす枠部２１を備えており、この枠部２１の内側に、配線器具本体１２を例えば縦に最大３個取付可能な開口部２３及び一対の器具支持部３が形成されている。この器具支持部３は、開口部２３を挟んで対向配置された２辺である。さらに、この枠部２１の上下には、長孔状の壁面取付用ねじ孔２５が形成され、この壁面取付用孔２５に挿入される壁面取付用ねじ（ボックスねじ）にて、サポート１１が図示しない配線ボックスにねじ止めされる。さらに、枠部２１の上下には、アダプタ取付用ねじ孔２６が形成され、このアダプタ取付用ねじ孔２６に螺合するアダプタ取付用ねじにて、アダプタ３０がサポート１１に固定される。
【００２９】
また、サポート１は、一方の器具支持部３ａに係合係止部５を備え、他方の器具支持部３ｂに可動係止部６を備え、これらの係合係止部５と可動係止部６とに配線器具本体１２を係止させて固定する。
【００３０】
なお、一対の器具支持部３は、開口部２３に挿入される配線器具本体１２の表面側の一部、ここでは止め金具１６の一部を裏面側で係止して支持する構造となっている。
【００３１】
係合係止部５は、枠部２１における一方の器具支持部３ａに設けられ、この器具支持部３ａの裏面に支持される配線器具本体１２の止め金具１６に設けられた係止爪１７を係止孔５１で係止する（図１及び図２を参照）。これらの係止孔５１は、配線器具本体１２が並列配置された場合、それらの配線器具本体１２の各々の係止爪１７が挿入され得る位置に形成されている。
【００３２】
また、係合係止部５が設けられた器具支持部３ａは、図２または図６に示したように、正面側から裏面側へと折り曲げられており、その端部５２が開口部２３側に向かって傾斜するように第一面取り５３が施されている（図４及び図５参照）。
【００３３】
また、係合係止部５は、開口部２３側から開口部２３側とは反対側である器具支持部３ａの外端面８に向かって傾斜するように第二面取り５４が施されている（図５参照）。
【００３４】
可動係止部６は、器具支持部３ｂにおける開口部２３を介して固定係止部５と対向する３箇所にそれぞれ設けられ、器具支持部３ｂの外端面８との間に僅かな隙間を開けて取り付けられ、その器具支持部３ｂの裏面に当接支持された配線器具本体１２の係止爪１７を器具支持部３ｂの裏面との間で挟持し、弾性変形することによって係止爪１２の挟持を行なう。つまり、図３に示したように、器具支持部３ｂには、器具支持部３ｂの端部から枠体４の裏面側に向けて延出する可動係止部取付片９が設けられている。この可動係止部取付片９は、図７に示すように、可動係止部６が設けられる３箇所の位置に空間部１０を有する。そして、このような可動係止部取付片９には、可動係止部６を形成する金属弾性９１１が取り付けられている。この金属弾性片９１は、例えば、厚さ０．３ｍｍ程度のステンレス（ＳＵＳ）を用いた金属部材であり、一端が折り曲げ加工されて可動係止部取付片９に巻き付き、他端が直角に曲げ加工されて器具支持部３ｂの裏面に固定されている。そして、金属弾性片９１には、可動係止部取付片９の３つの空間部１０に独立して位置付けられる切欠部分が形成され、これらの切欠部分が可動係止部６として形成されている。このような可動係止部６は、空間部１０に位置することから、何れの方向にも弾性変形が可能である。
【００３５】
また可動係止部６には、中央部分が上方に突出する高い部分となり、その両側に中央部よりも低い一対の係止作用部１３が形成されている。これらの係止作用部１３が、器具本体１２の係止爪１７を器具支持部３ｂの裏面との間で挟持する作用をもたらす。
【００３６】
またサポート１は、図１、図４及び図６に示すように、一対の器具支持部３ａ、３ｂよりも枠部２１の長手方向に延出された枠部２１の長手方向から見て断面コの字状の第１、第２、第３及び第４の補強枠部４ｄ、４ｃ、４ｂ、４ａが設けられている。すなわち、第 1 補強枠部４ｄは、一方の器具支持部である器具支持部３ａよりも枠部２１の長手方向に延出された枠部２１の長手方向から見て開口部２３よりも一面４ｆ側とは反対側である他面４ｇ側に突出する断面コの字状に形成されている。また、第２補強枠部４ｃは、一面４ｆ側及び他面４ｇ側から見てコ字状に切欠かれて形成されている切欠き４ｅを介して前記第１補強枠部４ｄから延出されて枠部２１の長手方向から見て開口部２３よりも他面４ｇ側に突出する断面コの字状に形成されている。また、第３補強枠部４ｂは、他方の器具支持部側である器具支持部３ｂよりも枠部２１の長手方向に延出された枠部２１の長手方向から見て開口部２３よりも他面４ｇ側に突出する断面コの字状に形成されている。また、第４補強枠部４ａは、器具支持部３ｂ側であって、前記切欠き４ｅと対向する位置に枠部２１の長手方向から見て開口部２３よりも他面４ｇ側に突出し、かつ他面４ｇ側から見て器具支持部３ｂよりも外側に突出する突出片４ａ１を備える断面コの字状に形成されている。
【００３７】
アダプタ３０は、図９に示すように、合成樹脂からなり、両端部３１、３１の内側にサポート１の開口部２３と対向するように窓部３２が形成されている。そして、アダプタ取付用ねじ孔２６に螺合するアダプタ取付用ねじが挿入されるねじ挿入孔３３が設けられた取付部３４が上下２個所に設けられている。
【００３８】
またアダプタ３０は、窓部３２と連続して形成され、かつ、両端部３１、３１と取付部３４との間に補強枠部除け部３５が設けられている。
【００３９】
化粧プレート４０は、図１０に示すように合成樹脂からなり、窓部３２と対向するように窓部４１が形成され、アダプタ３０に設けられた化粧プレート取付孔３６，３６…に嵌合するように図示しない突起部を設けている。
【００４０】
操作体であるハンドル５０は、図１１に示すように窓部３２と略同様の大きさに形成されており、裏側には配線器具本体１２のハンドル受け１３ａに係合保持される図示しない保持部が形成されている。
【００４１】
本実施形態の配線器具１００は、まず、サポート１の背面側から器具支持部３ａの係合係止部５へ配線器具本体１２の一方の係止爪１７を係止させる。そして、係合係止部５に係止させた係止爪１７を支点として他方の器具支持部３ｂの可動係止部６の係止作用部１３に係止させるようにサポート１の正面側へ回動させることによって他方の係止爪１７を可動係止部６へ係止させることによって配線器具本体１２をサポート１に取付ける。次に、配線器具本体１２が取付けられたサポート１を壁面等に埋め込まれた配線ボックスにサポート取付用ねじによって取付ける。
【００４２】
この時、配線ボックスへサポート１を取付ける際には、壁面取付用ねじ孔２５を支点として配線ボックス側へサポート１が引っ張られるが、補強枠部４ａ，４ｂ，４ｃ，４ｄによりサポート１の器具支持部３ａ、３ｂが撓むことを防いでいる。
【００４３】
そして、壁面に取付けられたサポート１にアダプタ３０をアダプタ取付用ねじによって取付けるが、この時、アダプタ３０をサポート１へ取付ける際には、ねじ挿入孔３３を支点として配線ボックス側へアダプタ３０が引っ張られるが、両端部３１、３１及び補強枠部除け部３５を介して設けられた取付部３４により、アダプタ３０の両端部３１，３１が撓むことを防いでいる（図１３参照）。
【００４４】
そして、アダプタ３０に化粧プレート４０を取付け、ハンドル５０を配線器具本体１２に係合させて取付けることによって、壁面に配線器具１００が取付けられる。
【００４５】
本実施形態によれば、一対の器具支持部３ａ、３ｂよりも枠部２１の長手方向に延出された枠部２１の長手方向から見て断面コの字状の補強枠部４ａ、４ｂ、４ｃ、４ｄがサポート１に設けられたことにより、配線ボックスへサポート１を取付ける際に生じる配線ボックス側へのサポート１の撓み力に対して補強枠部４ａ、４ｂ、４ｃ、４ｄが充分に耐え得ることができるので、サポート１が撓むことを防ぐことができるるとともに、サポート１が撓みにくいので、サポート１とへ取付けるアダプタ３０、化粧プレート４０等にも撓みを生じにくくでき、壁面とアダプタ３０等との間に隙間を生じさせることがなく、外観上も良好なものとすることができる。
【００４６】
さらに、補強枠部４ａ、４ｂ、４ｃ、４ｄを有するサポート１と、両端部３１，３１、この両端部３１、３１及び補強枠部除け部３５を介して設けられた取付部３４を有するアダプタ３０を具備するので、アダプタ３０をサポート１へ取付ける際にまれに生じる配線ボックス側へのアダプタの撓み力が両端部３１，３１へ伝わらないので、アダプタ３０自体が撓むことを防ぐことができるので、壁面とアダプタ３０等との間に隙間を生じさせることをより防ぎ、外観上も更に確実に良好なものとすることができる。
【００４７】
さらに、係合係止部５が設けられた器具支持部３ａに第一面取り５３、係合係止部５に第二面取り５４が施されているので、配線器具本体１２をサポート１に取付ける作業性を向上させることができる。
【発明の効果】
請求項１記載の発明によれば、サポートを壁面へ取付ける際にサポートに撓みを生じさせないことに加えて、アダプタをサポートへ取付ける際にまれに生じる壁面取付手段へ作用するアダプタの撓み力が両端部へ伝わらないので、アダプタ自体が撓むことを防ぐことができ、壁面とアダプタ等との間に隙間を生じさせることをより防ぎことができる、したがって、外観上も更に確実に良好なものとすることができる。
