Description

【０００１】
【発明の属する技術分野】
本発明は、スイッチやコンセントなどの配線器具を壁面などの造営面に埋込配設するために用いられる配線器具用取付枠に関するものである。
【０００２】
【従来の技術】
従来より、スイッチやコンセントのような配線器具を壁面等の造営面に埋込配設するために、図１７及び図１８に示すような金属製の配線器具用取付枠（以下、取付枠と言う。）Ａが用いられている。この取付枠Ａは、壁に埋設された埋込ボックス６０の開口面側に取付ねじ（ボックスねじ）６１，６１によって取り付けられ、さらに合成樹脂製のプレー
ト枠６２がねじ６３，６３により前面に取着されるとともに、プレート枠６２の前面に化粧プレート６４が被着されるようになっている。
【０００３】
また、取付枠Ａの両側部２ａ，２ｂには配線器具５０の組立枠５２，５２に設けられた溝部５２ａに係合する係合突起５ａ，５ｂが設けられ、且つ一方の側部２ｂに溝孔６５が設けられて開口窓４との間で薄肉部６６が形成されている。ここで、取付枠Ａへの配線器具５０の取り付けは、配線器具５０の一部を取付枠Ａの開口窓４に挿入するようにして一方の側部２ａの係合突起５ａを片側の組立枠５２の溝部５２ａに係合し、溝孔６５にドライバ等の工具を挿入してこじることにより薄肉部６６を突出変形させて他方の側部２ｂの係合突起５ｂを反対側の組立枠５２の溝部５２ａに係合することで行われる。
【０００４】
【発明が解決しようとする課題】
上述した配線器具用取付枠では、配線器具５０を取付枠Ａに取り付ける際に取付枠Ａの開口窓４に一部を挿入した状態に配線器具５０を作業者が手で位置決めし且つ保持しながらドライバ等の工具によって薄肉部６６を突出変形させなければならず、作業性が悪いという問題があった。
【０００５】
本発明は上記事情に鑑みて為されたものであり、その目的とするところは、配線器具を容易に取り付けることができる配線器具用取付枠を提供することにある。
【０００６】
【課題を解決するための手段】
上記目的を達成するために、請求項１の発明では、対向する一対の側部並びに両側部を連結する連結部を有し側部と連結部とで囲まれた開口窓に単位寸法の配線器具の一部を挿入した形で配線器具を複数個並べて保持する枠本体と、枠本体を壁面のような造営面に固定する固定手段と、一方の側部から開口窓側へ突出し各配線器具の側面にそれぞれ設けられた溝部に各々係合する複数の係合突起と、他方の側部に設けられ、各配線器具の側面にそれぞれ突出する突出部に各々係脱自在に係止する複数の係止片とを備え、複数の係止片は可撓性を有する材料により一体に形成され、他方の側部にかしめ固定される固定部と、突出部が係止する切欠部を有して固定部の背面から背面側に向かって突設された保持部と、保持部の先端側に設けられ、背面側に行くほど外側への突出量が大きくなるように傾斜する傾斜部とを具備することを特徴とし、複数の係止片は可撓性を有する材料で形成されているので、配線器具の溝部と係合突起とを係合させた状態で、配線器具の突出部と係止片とを係止片のばね力によって係止させることができ、従来の取付枠のように取付枠をこじて変形させることによって、配線器具を取付枠に保持させる場合に比べて、取付作業を容易に行うことができる。しかも複数の係止片は一体に形成されているので、複数の係止片を一度に枠本体に固定することができ、取付枠を組み立てる手間を少なくできる。
【０００７】
請求項２の発明では、対向する一対の側部並びに両側部を連結する連結部を有し側部と連結部とで囲まれた開口窓に単位寸法の配線器具の一部を挿入した形で配線器具を複数個並べて保持する枠本体と、枠本体を壁面のような造営面に固定する固定手段と、一方の側部から開口窓側へ突出し各配線器具の側面にそれぞれ設けられた溝部に各々係合する複数の係合突起と、他方の側部に設けられ、各配線器具の側面にそれぞれ突出する突出部に係脱自在に係止する複数の係止片とを備え、複数の係止片は可撓性を有する材料により一体に形成され、他方の側部にかしめ固定される固定部と、当該固定部から背面側に向かって突設されて前記突出部を保持する保持部とを備え、保持部の中間部に開口窓側に突出する凸部を設けて成ることを特徴とし、係止片は可撓性を有する材料で形成されているので、配線器具の溝部と係合突起とを係合させた状態で、配線器具の突出部と係止片とを係止片のばね力によって係止させることができ、従来の取付枠のように取付枠をこじて変形させることによって、配線器具を取付枠に保持させる場合に比べて、取付作業を容易に行うことができる。しかも、複数の係止片は一体に形成されているので、複数の係止片を一度に枠本体に固定することができ、取付枠を組み立てる手間を少なくできる。
【０００８】
【発明の実施の形態】
本発明の実施の形態を図面を参照して説明する。
【０００９】
（参考例１）
本参考例の配線器具用取付枠について図１（ａ）（ｂ）を参照して説明する。この配線器具用取付枠（以下、取付枠と言う。）Ａの枠本体１は金属製であって、対向する一対の側部２ａ，２ｂと、両側部２ａ，２ｂを連結する連結部３，３と、側部２ａ，２ｂ及び連結部３，３で囲まれた開口窓４とを有する矩形枠状に形成されている。また、各連結部３，３には、枠本体１を埋込ボックス６０に取り付けるための取付ねじ６１（図１８参照）が挿通される長孔状のねじ挿通孔３ａと、壁面を形成する壁パネル等の壁材に枠本体１を取り付けるための挟み金具（図示せず）が係止される挟み金具係止溝３ｂ，３ｂと、プレート枠６２を取り付けるためのねじ６３が螺合するねじ孔３ｃとが設けてある。ここに、ねじ挿通孔３ａや挟み金具係止溝３ｂなどから、枠本体１を壁面のような造営面に固定する固定手段が構成される。
【００１０】
一対の側部２ａ，２ｂは長手方向に沿った外側（開口窓４と反対側）の端縁が前方へ折曲されており、両側部２ａ，２ｂの長手方向に沿った内側（開口窓４に臨む側）の端縁には、開口窓４側に突出して配線器具５０の組立枠５２に設けられた溝部５２ａに係合する係合突起５が長手方向に沿って等間隔に３個づつ設けてある。ここで、以下の参考例および実施形態においては、規格化された単位寸法の配線器具（例えば、日本工業規格に規定された大角形連用配線器具（ＪＩＳＣ８３０４参照）の１個モジュール寸法）を短幅方向に３個並べて取り付けることができるように枠本体１並びに開口窓４の寸法が設定してある。
【００１１】
また、一方の側部２ｂには、係止片としての係合突起５にそれぞれ対応する部位に溝孔６が穿設されており、開口窓４と溝孔６との間で、係合突起５の突設された部位を側部２ｂに連結する可撓性を有する連結片７が形成されており、係合突起５は連結片７によって開口窓４側にばね付勢されている。尚、側部２ｂに設けた係合突起５の背面側には面取り加工が施され、背面側から前面側に近付くにつれて開口窓４側への突出量が大きくなるように傾斜する傾斜面５ｃが形成されている。
【００１２】
ここで、取付枠Ａに配線器具５０を取り付ける際は、配線器具５０の一部（器具本体５１の前面に突出するボス部５１ａ）を枠本体１の背面側から開口窓４内に挿入するようにして、一方の組立枠５２の溝部５２ａに一方の側部２ａに設けた係合突起５を係合させ、さらにその状態から器具本体５１を枠本体１の方へ押し付けていくと、他方の組立枠５２が他方の側部２ｂに設けた係合突起５の傾斜面５ｃに当接し、係合突起５が組立枠５２に押されて連結片７が外側に撓められ、係合突起５が外側（開口窓４と反対側）に後退する。そこからさらに器具本体５１を枠本体１の方へ押し付けると、係合突起５が組立枠５２を乗り越え、連結片７のばね復帰力によって係合突起５が内側（開口窓４側）へ移動し、係合突起５と組立枠５２の溝部５２ａとが係合して、器具本体５１が取付枠Ａに取り付けられるのである。このように、係合突起５は連結片７のばね力によって内側に付勢されており、連結片７のばね力によって係合突起５が組立枠５２の溝部５２ａと係合するので、従来の取付枠Ａのように、溝孔６５にドライバ等の工具を挿入してこじることにより薄肉部６６を突出変形させ、係合突起５ｂを組立枠５２の溝部５２ａと係合させる場合に比べて取り付けの手間を少なくできる。また、係合突起５は連結片７を介して枠本体１に一体に連結されており、取付枠Ａは金属板に打ち抜き加工を施すことによって形成されるので、取付枠Ａを容易に形成することができる。
【００１３】
（参考例２）
本参考例の配線器具用取付枠について図２乃至図５を参照して説明する。尚、側部２ｂ及び係止片１０以外の構成は参考例１の取付枠Ａと同様であるので、同一の構成要素には同一の符号を付して、その説明を省略する。
【００１４】
一対の側部２ａ，２ｂは長手方向に沿った外側の端縁が前方へ折曲されており、一方の側部２ａの長手方向に沿った内側の端縁には、開口窓４の方へ突出し配線器具５０の組立枠５２に設けられた溝部５２ａに係合する係合突起５が長手方向に沿って等間隔に３個設けてある。
【００１５】
他方の側部２ｂにはスリット状の３つの貫通孔８が長手方向に沿って列設されている。また、側部２ｂにおける貫通孔８の外側の端縁からは背面側に突出する垂下片９がそれぞれ突設されており、図２及び図４に示すように、貫通孔８に一部を挿通した状態で垂下片
９に係止片１０がそれぞれかしめ固定される。
【００１６】
係止片１０は、図５に示すように、可撓性（ばね性）を有する短冊状の金属片を折曲加工して、断面略Ｖ字状に形成されており、垂下片９における外側の面にかしめ固定される固定部１１と、固定部１１の背面側の端縁から前面側に向かって延設され、前面側に行くほど内側への突出量が大きくなるように傾斜し、配線器具５０の組立枠５２に突設された係止爪（突出部）５２ｂを保持する保持部１２と、保持部１２の先端部から側部２ｂと略直交する方向に延設され貫通孔８を介して側部２ｂの前面側に突出する操作部１３とを具備している。尚、操作部１３の幅寸法は保持部１２の幅寸法よりも小さい寸法に形成されており、操作部１３の両側には係止段部１２ａ，１２ａが形成されている。また、固定部１１には垂下片９の外側の面に突設された固定用突起９ａを挿通する挿通孔１１ａが設けられており、垂下片９の固定用突起９ａを挿通孔１１ａに通して、固定用突起９ａの先端をかしめることで固定部１１が垂下片９に固定される。
【００１７】
そして、取付枠Ａに配線器具５０を取り付ける際は、配線器具５０の一部（器具本体５１の前面に突出するボス部５１ａ）を枠本体１の背面側から開口窓４内に挿入するようにして、一方の組立枠５２の溝部５２ａに一方の側部２ａに設けた係合突起５を係合させる。さらにその状態から器具本体５１を枠本体１の方へ押し付けていくと、他方の組立枠５２に突設されている一対の係止爪５２ｂ，５２ｂが係止片１０の保持部１２に当接し、保持部１２が係止爪５２ｂ，５２ｂによって外側に押されて撓められる。そこからさらに器具本体５１を枠本体１の方へ押し付けると、係止爪５２ｂ，５２ｂが保持部１２を乗り越え、保持部１２のばね復帰力によって係止爪５２ｂ，５２ｂと係止片１０の係止段部１２ａ，１２ａとがそれぞれ係止し、器具本体５１が取付枠Ａに取り付けられるのである。また、取付枠Ａから配線器具５０を取り外す際は、貫通孔８から前面側に突出する操作部１３を外側に押すと、保持部１２が外側に撓められて、配線器具５０の係止爪５２ｂと係止段部１２ａとの係止状態が解除されるので、配線器具５０を取付枠Ａから容易に取り外すことが出来る。
【００１８】
このように、係止片１０のばね力によって係止爪５２ｂ，５２ｂと係止片１０の係止段部１２ａ，１２ａとがそれぞれ係止し、器具本体５１が取付枠Ａに取り付けられるので、従来の取付枠Ａのように、溝孔６５にドライバ等の工具を挿入してこじることにより薄肉部６６を突出変形させ、係合突起５ｂを組立枠５２の溝部５２ａと係合させる場合に比べて取り付けの手間を少なくできる。また、係止片１０は、垂下片９における開口窓４と反対側の面にかしめ固定されているので、取付枠Ａが背面側から落下したとしても、落下衝撃を垂下片９で受けることができるから、係止片１０をかしめ固定する固定部１１に落下衝撃が加わることはなく、係止片１０が変形するのを防止できる。
【００１９】
（参考例３）
本参考例の配線器具用取付枠について図６乃至図９を参照して説明する。尚、係止片１０以外の構成は参考例２の取付枠Ａと同様であるので、同一の構成要素には同一の符号を付して、その説明を省略する。
【００２０】
係止片１０は、図９に示すように、可撓性（ばね性）を有する短冊状の金属片を折曲加工して形成されており、垂下片９における内側の面にかしめ固定される固定部１１と、固定部１１の端縁から前面側に向かって延設され、前面側に行くほど内側への突出量が大きくなるように形成され、配線器具５０の係止爪５２ｂを保持する保持部１２と、保持部１２の先端部から側部２ｂと略直交する方向に延設され貫通孔８を介して側部２ｂの前面側に突出する操作部１３とを具備している。尚、操作部１３の幅寸法は保持部１２の幅寸法よりも小さい寸法に形成されており、操作部１３の両側には係止段部１２ａ，１２ａが形成されている。また、固定部１１には垂下片９における内側の面に突設された固定用突起９ｂを挿通する挿通孔１１ａが設けられており、垂下片９の固定用突起９ｂを挿通孔１１ａに通して、固定用突起９ｂの先端をかしめることで固定部１１が垂下片９に固定される。
【００２１】
ここで、取付枠Ａに配線器具５０を取り付ける際は、配線器具５０の一部（器具本体５１の前面に突出するボス部５１ａ）を枠本体１の背面側から開口窓４内に挿入するようにして、一方の組立枠５２の溝部５２ａに一方の側部２ａに設けた係合突起５を係合させる。さらにその状態から器具本体５１を枠本体１の方へ押し付けていくと、他方の組立枠５２に突設されている一対の係止爪５２ｂ，５２ｂが係止片１０の保持部１２に当接し、保持部１２が係止爪５２ｂ，５２ｂによって外側に押されて撓められる。そこからさらに器具本体５１を枠本体１の方へ押し付けると、係止爪５２ｂ，５２ｂが保持部１２を乗り越え、保持部１２のばね復帰力によって係止爪５２ｂ，５２ｂと係止片１０の係止段部１２ａ，１２ａとが係止し、器具本体５１が取付枠Ａに取り付けられるのである。また、取付枠Ａから配線器具５０を取り外す際は、貫通孔８から前面側に突出する操作部１３を外側に押すと、保持部１２が外側に撓められて、配線器具５０の係止爪５２ｂと係止段部１２ａとの係止状態が解除されるので、配線器具５０を取付枠Ａから容易に取り外すことが出来る。
【００２２】
このように、係止片１０のばね力によって係止爪５２ｂ，５２ｂと係止片１０の係止段部１２ａ，１２ａとがそれぞれ係止し、器具本体５１が取付枠Ａに取り付けられるので、従来の取付枠Ａのように、溝孔６５にドライバ等の工具を挿入してこじることにより薄肉部６６を突出変形させ、係合突起５ｂを組立枠５２の溝部５２ａと係合させる場合に比べて取り付けの手間を少なくできる。また、係止片１０は、垂下片９における開口窓４側の面にかしめ固定されているので、取付枠Ａが背面側から落下したとしても、落下衝撃を垂下片９で受けることができるから、係止片１０をかしめ固定する固定部１１に落下衝撃が加わることはなく、係止片１０が変形するのを防止できる。
【００２３】
（実施形態１）
本実施形態の配線器具用取付枠について図１０乃至図１２を参照して説明する。上述した参考例２又は３の配線器具用取付枠では、一方の側部２ｂに３個の係止片１０をかしめ固定しているが、本実施形態では３個の係止片１０を一体化した係止部材１０’を側部２ｂにかしめ固定している。尚、係止部材１０’以外の構成は参考例２又は３の配線器具用取付枠と同様であるので、同一の構成要素には同一の符号を付して、その説明を省略する。
【００２４】
係止部材１０’は可撓性を有する材料から形成され、側部２ｂの前面側にかしめ固定される長尺の固定部１１と、固定部１１の背面における各貫通孔８に対応する部位から背面側に向かってそれぞれ突設され、配線器具５０の係止爪５２ｂを保持する保持部１２とを備えており、保持部１２の先端部には、背面側に行くほど外側への突出量が大きくなるように形成された傾斜部１４が形成されている。また、保持部１２の両側縁には、それぞれ、側方に開放された切欠部１２ｂ，１２ｂが形成されている。尚、固定部１１には、側部２ｂの前面に突設された複数個（本実施形態では例えば４個）の固定用突起２ｃをそれぞれ挿通する複数個（本実施形態では例えば４個）の挿通孔１１ｂが設けられており、側部２ｂの固定用突起２ｃを挿通孔１１ｂに通して、固定用突起２ｃの先端をかしめることで係止部材１０’が側部２ｂに固定される。
【００２５】
ここで、取付枠Ａに配線器具５０を取り付ける際は、配線器具５０の一部（器具本体５１の前面に突出するボス部５１ａ）を枠本体１の背面側から開口窓４内に挿入するようにして、一方の組立枠５２の溝部５２ａに一方の側部２ａに設けた係合突起５を係合させる。さらにその状態から器具本体５１を枠本体１の方へ押し付けていくと、他方の組立枠５２に突設されている一対の係止爪５２ｂ，５２ｂが係止部材１０’の傾斜部１４に当接し、傾斜部１４が係止爪５２ｂ，５２ｂによって外側に押されて撓められる。そこからさらに器具本体５１を枠本体１の方へ押し付けると、係止爪５２ｂ，５２ｂが傾斜部１４に案内されて前面側へ移動して保持部１２を乗り越え、保持部１２のばね復帰力によって係止爪５２ｂ，５２ｂと係止部材１０’の切欠部１２ｂ，１２ｂとがそれぞれ係止し、器具本体５１が取付枠Ａに取り付けられるのである。
【００２６】
このように、係止部材１０’のばね力によって係止爪５２ｂ，５２ｂと係止部材１０’の係止段部１２ｃ，１２ｃとがそれぞれ係止し、器具本体５１が取付枠Ａに取り付けられるので、従来の取付枠Ａのように、溝孔６５にドライバ等の工具を挿入してこじることにより薄肉部６６を突出変形させ、係合突起５ｂを組立枠５２の溝部５２ａと係合させる場合に比べて取り付けの手間を少なくできる。また、本実施形態では複数個（本実施形態では３個）の係止片を一体に形成しているので、複数個の係止片をそれぞれ枠本体１に溶着したりかしめ固定する場合に比べて、係止部材１０’を取り付ける手間を少なくできる。
【００２７】
（実施形態２）
本実施形態の配線器具用取付枠について図１３及び図１４を参照して説明する。尚、側部２ｂ及び係止部材１０’以外の構成は実施形態１の取付枠と同様であるので、同一の構成要素には同一の符号を付して、その説明を省略する。
【００２８】
枠本体１の一方の側部２ａは、長手方向に沿った外側の端縁が前方へ折曲されており、長手方向に沿った内側の端縁には、開口窓４の方へ突出し配線器具５０の組立枠５２に設けられた溝部５２ａに係合する係合突起５が長手方向に沿って等間隔に３個設けてある。
【００２９】
また他方の側部２ｂにおける外側の端縁からは背面側に突出する垂下片９が突設されている。側部２ｂ及び垂下片９には、側部２ｂから垂下片９にわたって開口するスリット状の貫通孔８ａが、側部２ｂの長手方向に沿って等間隔に３個設けてあり、さらに貫通孔８ａに対して背面側の垂下片９の部位には垂下片９を貫通するスリット状の貫通孔８ｂがそれぞれ穿設されている。
【００３０】
係止部材１０’は可撓性を有する材料から形成され、側部２ｂの前面側にかしめ固定される長尺の固定部１１と、固定部１１の外側の端縁における貫通孔８ａに対応する部位から背面側に向かってそれぞれ突設され、配線器具５０の係止爪５２ｂを保持する保持部１５とを備えている。ここで、保持部１５の中間部には内側（開口窓４側）に突出する凸部１５ａが設けられている。
【００３１】
尚、固定部１１には、側部２ｂの前面に突設された複数個（本実施形態では例えば６個）の固定用突起２ｃをそれぞれ挿通する複数個（本実施形態では例えば６個）の挿通孔１１ｂが設けられており、側部２ｂの固定用突起２ｃを挿通孔１１ｂに通して、固定用突起２ｃの先端をかしめることで係止部材１０’が側部２ｂに固定される。
【００３２】
ここで、取付枠Ａに配線器具５０を取り付ける際は、配線器具５０の一部（器具本体５１の前面に突出するボス部５１ａ）を枠本体１の背面側から開口窓４内に挿入するようにして、一方の組立枠５２の溝部５２ａに一方の側部２ａに設けた係合突起５を係合させる。さらにその状態から器具本体５１を枠本体１の方へ押し付けていくと、他方の組立枠５２に突設されている一対の係止爪５２ｂ，５２ｂが係止部材１０’の保持部１５に当接し、保持部１５が係止爪５２ｂ，５２ｂによって外側に押されて撓められる。そこからさらに器具本体５１を枠本体１の方へ押し付けると、係止爪５２ｂ，５２ｂが保持部１５の凸部１５ａを乗り越え、保持部１５のばね復帰力によって係止爪５２ｂ，５２ｂが保持され、器具本体５１が取付枠Ａに取り付けられるのである。
【００３３】
一方、取付枠Ａから配線器具５０を取り外す際は、図１４（ａ）（ｂ）に示すように、固定部１１の前面に形成された工具挿入口１１ｃから例えばマイナスドライバー７０の先端を挿入し、保持部１２を外側に押し撓めることにより、保持部１２と係止爪５２ｂとの係止状態が解除され、配線器具５０を容易に取り外すことが出来る。
【００３４】
このように、係止部材１０’のばね力によって係止爪５２ｂ，５２ｂと係止部材１０’の凸部１５ａとがそれぞれ係止し、器具本体５１が取付枠Ａに取り付けられるので、従来の取付枠Ａのように、溝孔６５にドライバ等の工具を挿入してこじることにより薄肉部６６を突出変形させ、係合突起５ｂを組立枠５２の溝部５２ａと係合させる場合に比べて取り付けの手間を少なくできる。また、本実施形態では複数個（本実施形態では３個）の係止片を一体に形成しているので、複数個の係止片をそれぞれ枠本体１に溶着したりかしめ固定する場合に比べて、係止部材１０’を取り付ける手間を少なくできる。
【００３５】
（参考例４）
本参考例の配線器具用取付枠について図１５を参照して説明する。上述した参考例３の配線器具用取付枠では、一方の側部２ｂに３個の係止片１０をかしめ固定しているが、本参考例では３個の係止片１０を一体化した係止部材１０’を側部２ｂにかしめ固定している。尚、係止部材１０’以外の構成は参考例３の配線器具用取付枠と同様であるので、同一の構成要素には同一の符号を付して、その説明を省略する。
【００３６】
係止部材１０’は可撓性を有する材料から形成され、側部２ｂに設けた垂下片９の内側の面にかしめ固定される長尺の固定部１１と、固定部１１の前面側の端縁から前面側に延設され、前面側に行くほど内側への突出量が大きくなり、配線器具５０の係止爪５２ｂを保持する保持部１２とを具備しており、保持部１２の前面側の端縁における各貫通孔８に対応する部位にはそれぞれ凹部１２ｄが形成されている。尚、固定部１１には、垂下片９における内側の面に突設された複数の固定用突起９ｂをそれぞれ挿通する複数の挿通孔１１ａが設けられており、垂下片９の固定用突起９ｂを挿通孔１１ａに通して、固定用突起９ｂの先端をかしめることで係止部材１０’が側部２ｂに固定される。
【００３７】
ここで、取付枠Ａに配線器具５０を取り付ける際は、配線器具５０の一部（器具本体５１の前面に突出するボス部５１ａ）を枠本体１の背面側から開口窓４内に挿入するようにして、一方の組立枠５２の溝部５２ａに一方の側部２ａに設けた係合突起５を係合させる。さらにその状態から器具本体５１を枠本体１の方へ押し付けていくと、他方の組立枠５２に突設されている一対の係止爪５２ｂ，５２ｂが係止部材１０’の保持部１２に当接し、保持部１２が係止爪５２ｂ，５２ｂによって外側に押されて撓められる。そこからさらに器具本体５１を枠本体１の方へ押し付けると、係止爪５２ｂ，５２ｂが保持部１２を乗り越え、保持部１２のばね復帰力によって係止爪５２ｂ，５２ｂが係止部材１０’の凹部１２ｄと係止し、器具本体５１が取付枠Ａに取り付けられるのである。
【００３８】
このように、係止部材１０’のばね力によって係止爪５２ｂ，５２ｂと係止部材１０’の凹部１２ｄとがそれぞれ係止し、器具本体５１が取付枠Ａに取り付けられるので、従来の取付枠Ａのように、溝孔６５にドライバ等の工具を挿入してこじることにより薄肉部６６を突出変形させ、係合突起５ｂを組立枠５２の溝部５２ａと係合させる場合に比べて取り付けの手間を少なくできる。また、本参考例では複数個（例えば３個）の係止片を一体に形成しているので、複数個の係止片をそれぞれ枠本体１に溶着したりかしめ固定する場合に比べて、係止部材１０’を取り付ける手間を少なくできる。しかも、係止部材１０’は、垂下片９における開口窓４側の面にかしめ固定されているので、取付枠Ａが背面側から落下したとしても、落下衝撃を垂下片９で受けることができるから、係止片１０をかしめ固定する固定部１１に落下衝撃が加わることはなく、係止片１０が変形するのを防止できる。
【００３９】
ところで、上述した実施形態２又は参考例４の配線器具用取付枠では、例えばフープ材に打ち抜き加工を施すことによって枠本体１及び係止部材１０’を夫々形成しているのであるが、図１６に示すように、係止部材１０’を金型で打ち抜いて一つ一つに分離する際に、同一の金型で係止部材１０’を枠本体１にかしめ固定している。
【００４０】
図１６は取付枠Ａを製造する各工程を示しており、図中の矢印はフープ材が移動する流れを示している。図１６の工程Ｗ１では、それぞれ打ち抜き加工の施された枠本体１の側部２ｂと係止部材１０’とが重ね合わせされ、同一の金型で枠本体１と係止部材１０’とをかしめ固定するとともに、係止部材１０’の打ち抜き加工が行われ、係止部材１０’が一つ一つに分離される。尚、図１６中の斜線部は打ち抜き加工によって切断される箇所を示している。そして、次の工程Ｗ２で係止部材１０’の不要な部分を切断した後、工程Ｗ３で側部２ｂの曲げ加工が行われる。このように、同一の金型で係止部材１０’の打ち抜き加工を行うと共に、係止部材１０’を枠本体１にかしめ固定しているおり、２つの作業を一度に行っているので、作業工程を削減することができ、生産性を向上させることができ、且つ、複数個の係止片が一体化された係止部材１０’を枠本体１にかしめ固定しているので、複数個の係止片を枠本体１に溶着したりかしめ固定する場合に比べて、組立の手間を少なくすることができる。尚、枠本体１及び係止部材１０’を打ち抜く工程とは別の工程で、係止部材１０’を枠本体１にかしめ固定するようにしても良いのは勿論のことであり、この場合でも複数個の係止片が一体化された係止部材１０’を枠本体１にかしめ固定しているので、複数個の係止片を枠本体１に溶着したりかしめ固定する場合に比べて、組立の手間を少なくすることができる。
