Description

【０００１】
【発明の属する技術分野】
この発明は、建築物内の壁材裏側に配置され、取付ビスにより配線器具を取付可能な配線器具取付枠に関するものである。
【０００２】
【従来の技術】
従来より、建築物内の壁材表面にコンセント等の配線器具を取り付けるため、四角枠状をなす配線器具取付枠がその開口が壁材側へ臨む状態で同壁材の裏側に設置されている。この配線器具取付枠は四角枠状の枠本体を備え、その周壁の上下に相対向する一対の側壁の内面には、それぞれ配線器具取付部が内方へ突設されている。各配線器具取付部にはそれぞれ前方へ臨む取付孔が形成され、各取付孔の内周面には取付ビスの雄ねじが螺合可能な雌ねじ部が形成されている。
【０００３】
そして、上記構成の配線器具取付枠において、取付ビスを使用して配線器具を取り付けるには、まず、配線器具を保持した保持枠に形成された上下一対の挿通孔から前記取付孔に取付ビスを挿通する。その取付ビスの雄ねじを雌ねじ部に螺合することにより、保持枠を介して配線器具が配線器具取付枠に取り付けられる。
【０００４】
ところが、取付ビスは配線器具の取付作業時に別途用意しなければならず非常に面倒であるという問題があった。そこで、枠本体の周壁の内面に一定間隔をおいて３箇所にビス保持部を構成する保持突片を並設し、隣接する保持突片間にそれぞれ一本ずつ前記取付ビスの軸部を保持させることが提案された。そして、配線器具を配線器具取付枠に取り付けるとき、取付ビスは保持突片間から取り外されて使用される。
【０００５】
【発明が解決しようとする課題】
ところが、枠本体の周壁の内面から枠本体内方へビス保持部を突設させた場合、配線器具を枠本体の内部に収容すると、配線器具とビス保持部とが接触したり、ビス保持部が枠本体の開口の一部を閉塞したりして配線器具を枠本体内に収容する作業が行いにくくなるという問題があった。
【０００６】
この発明は、このような従来技術に存在する問題点に着目してなされたものである。その目的とするところは、配線器具の枠本体の内部への収容及び取付作業の際の不具合をなくすことができるビス保持部を備えた配線器具取付枠を提供することにある。
【０００７】

【００１３】
請求項７に記載の発明の配線器具取付枠は、請求項１又は請求項４に記載の発明において、前記枠本体は、四角枠状に形成されているものである。
【００１５】
【発明の実施の形態】
以下、この発明の実施形態を、図面に基づいて詳細に説明する。
（第１実施形態）
図１に示すように、配線器具取付枠１１は、略四角枠状をなす金属板製の枠本体１９を備え、その枠本体１９の周壁には、同枠本体１９に配線器具（図示せず）を取り付けるための取付ビス１５を保持可能なビス保持部１４が設けられているものである。ビス保持部１４は保持された取付ビス１５を枠本体１９の前面側に位置させるように設けられている。さらに、枠本体１９に取り付けられる前記配線器具との接触を防止するために枠本体１９から折り取り除去又は枠本体１９の後面側へ移動可能に設けられているものである。なお、本実施形態において、前記配線器具はコンセント、スイッチ、テレビ端子、モジュラージャック等を含む概念とする。
【００１６】
まず、枠本体１９について説明すると、枠本体１９は略長方形状をなす金属板を、前記ビス保持部１４が形成される部分が残存するようにその他の部分を打ち抜き除去して略四角枠状に形成されている。また、金属板の上端縁、下端縁及び左端縁にはそれぞれ外側壁２１が折り曲げ形成され、上下両外側壁２１の先端部にはバインド線２６ａ等の線材を結束可能に切り欠き形成されている。さらに、金属板に形成された開口の内周縁には金属板に対して略垂直に内側壁２２が折り曲げ形成され、それら外側壁２１及び内側壁２２により枠本体１９の周壁が形成されている。
【００１７】
上下両内側壁２２の相対向する中央部下端縁からは、それぞれ配線器具取付部２８が枠本体１９内方へ突設され、各配線器具取付部２８には枠本体１９の開口側に臨む取付孔２８ａが形成されている。各取付孔２８ａの内周面には前記取付ビス１５の雄ねじが螺合可能な雌ねじが螺刻された雌ねじ部（図示せず）が形成されている。
【００１８】
左外側壁２１の上下両端部にはそれぞれ先端部が先細に尖る形状をなす一対の固定突片１６が、左外側壁２１に対して略垂直に外方へ切り起こすことにより形成されている。そして、図４に破線に示すように、各固定突片１６を建築物内に立設された柱１２に対して差し込むことにより、図４に示すように、配線器具取付枠１１を前記柱１２に取り付け可能に構成されている。また、図２に示すように、左外側壁２１には固定孔１７が３箇所に形成され、各固定孔１７から固定ビス（図示せず）を柱１２に固定することにより前記固定突片１６とともに、配線器具取付枠１１を柱１２に取付可能に構成されている。さらに、その取付状態において、図５に示すように、配線器具取付枠１１の前方には壁材１３が設置され、その壁材１３の裏側に配線器具取付枠１１が設置されている。
【００１９】
次いで、前記ビス保持部１４について説明すると、図１及び図２に示すように、ビス保持部１４は四角板状をなす保持部本体１４ａを備えている。その保持部本体１４ａは左内側壁２２の中央部下端縁から同左内側壁２２の長さ方向に沿って所定幅を有する状態で枠本体１９内方へ突設されている。ビス保持部１４は保持部本体１４ａの平面部分が枠本体１９の開口に臨むとともに、枠本体１９の前面側より後退した位置に配置されている。
【００２０】
そして、保持部本体１４ａの前面と枠本体１９の前端面との間には、図３に示す壁材切除手段３７を構成する穿孔ビット３８の先端部に形成された非切除部４０の内側壁２２内周面に沿った移動を可能とする空間が確保されている。
【００２１】
また、図１に示すように、保持部本体１４ａの基端部中央部は、左内側壁２２の長さ方向に沿って切り欠き除去され、その切り欠かれた部分により保持部本体１４ａの枠本体１９からの折り取り又は折り曲げ作業の簡易化を図る補助手段が構成されている。そして、保持部本体１４ａは基端部の上下両端部の２箇所で左内側壁２２に連結され、前記２箇所の連結部分を折り曲げて切断することにより、保持部本体１４ａを枠本体１９から除去することが可能に構成されている。
【００２２】
保持部本体１４ａの中央部には、保持部本体１４ａの上側中央部及び下側中央部をそれぞれ保持部本体１４ａの中央部側へ四角形状に切り起こすことにより相対向する一対の第１突片１４ｂが形成され、それら第１突片１４ｂは保持部本体１４ａ前面から枠本体１９の前面側へ突設されている。さらに、保持部本体１４ａをその左側部及び右側部をそれぞれ保持部本体１４ａの中央部側へ四角形状に切り起こすことにより一対の第２突片１４ｃが形成され、それら第２突片１４ｃは保持部本体１４ａ前面から枠本体１９の前面側へ突設されている。
【００２３】
各第２突片１４ｃの先端部はそれぞれ第１突片１４ｂ側へ円弧状に膨らむ状態に曲げ形成されている。そして、保持部本体１４ａに第１及び第２突片１４ｂ，１４ｃが形成されることによりビス保持部１４が形成されている。保持部本体１４ａにおいて、一対の第１突片１４ｂの左側端面と左側の第２突片１４ｃとの間及び一対の第１突片１４ｂの右側端面と右側の第２突片１４ｃとの間にそれぞれ取付ビス１５が保持可能に形成され、保持された取付ビス１５の前方への抜け出しが前記膨出部分により規制されている。保持部本体１４ａに一対の取付ビス１５が保持された状態において、各取付ビス１５は枠本体１９内における前面側に配置されている。
【００２４】
壁材切除手段３７は、図３に示すように、切除工具３７ａの回転により壁材１３を切除可能な穿孔ビット３８を備えている。その穿孔ビット３８はビット軸３８ａの回転により前記壁材１３を切除可能に形成された切除刃部３９と、同切除刃部３９の先端側に設けられた非切除部４０とから構成されているものである。ビット軸３８ａの基端側（図３では右端側）には略円柱状をなし、図３に２点鎖線に示す切除工具３７ａの先端に取付可能なシャンク３８ｂが設けられている。非切除部４０のビット軸３８ａの長さ方向への長さは保持部本体１４ａの前面と枠本体１９の前端面との間の長さより若干短く形成されている。
【００２５】
上記構成の穿孔ビット３８において、シャンク３８ｂを切除工具３７ａの先端側にセットすることにより壁材切除手段３７が構成され、切除工具３７ａにより穿孔ビット３８を回転させることができるように構成されている。
【００２６】
前記配線器具取付枠１１を使用した配線器具の取付方法について記載する。
まず、枠本体１９の前端面と柱１２の前面とが面一となるように図４に示すように、配線器具取付枠１１を固定突片１６により柱１２に取り付け、さらに、ケーブル２６を枠本体１９内に引き込む。そして、ケーブル２６をバインド線２６ａにより保持した状態でそのバインド線２６ａを外側壁２１の切り欠き部分に係止させて結束し、ケーブル２６を枠本体１９に固定する。次いで、図５に示すように、配線器具取付枠１１の前方位置に壁材１３を設置し、配線器具取付枠１１を壁材１３の裏側に配置する。
【００２７】
次に、壁材１３の表側から配線器具取付枠１１の開口内の任意の位置に、穿孔ビット３８が通過可能な孔を形成し、その孔内に非切除部４０及び切除刃部３９を挿入させる。そして、切除工具３７ａにより穿孔ビット３８を回転させ、切除刃部３９により壁材１３を切除しながら切除工具３７ａを介して穿孔ビット３８を周壁側へ移動させ、非切除部４０を内側壁２２内面に当接させる。
【００２８】
次いで、穿孔ビット３８を内側壁２２の内周面に沿って移動させて、その穿孔ビット３８により壁材１３を切除する。このとき、図５に示すように、保持部本体１４ａは左内側壁２２の前端面より後退した位置から枠本体１９内へ突設されている。そのため、穿孔ビット３８が移動するとき、穿孔ビット３８がビス保持部１４に接触するのが防止される。そして、穿孔ビット３８の壁材１３の切除により、図６に示すように、配線器具取付枠１１の開口の内周形状に沿った形状をなす透孔３１が壁材１３に穿設され、枠本体１９の開口が壁材１３の表側に臨む。
【００２９】
続いて、前記透孔３１から枠本体１９内へ手を挿入し、ビス保持部１４に保持された取付ビス１５をそれぞれ指で摘んで取外す。このとき、ビス保持部１４、即ち取付ビス１５は枠本体１９の前面側に配置されているため、手を枠本体１９の奥方まで挿入することなく取付ビス１５を指で摘むことが可能となる。
【００３０】
一対の取付ビス１５をそれぞれビス保持部１４から取り外した後、保持部本体１４ａを指で摘み、前後方向へ折り曲げる作業を繰り返して枠本体１９から折り取る。このとき、保持部本体１４ａは基端部の上下両端部のみで左内側壁２２と連結されているため前記折り取り作業が容易に行われる。なお、保持部本体１４ａを枠本体１９から折り取らず、左内側壁２２と保持部本体１４ａの基端部との連結部分を中心にして後方へ折り曲げて枠本体１９の後面側へ移動させてもよい。
【００３１】
最後に、図７に示すように、配線器具３３にケーブル２６を接続するとともに、保持枠３２に配線器具３３を保持させる。このとき、配線器具３３とケーブル２６との接続作業の簡易化を図るためバインド線２６ａを除去してもよく、図示しないがバインド線２６ａをそのままにしてもよい。とその保持枠３２の上下両端部に形成された挿通孔３４から雌ねじ部に取付ビス１５を螺合して保持枠３２を介して配線器具３３を配線器具取付枠１１に取り付ける。このとき、ビス保持部１４は枠本体１９内から除去されているため、配線器具３３を枠本体１９の内部に収容するとき、配線器具３３がビス保持部１４に接触したり、ビス保持部１４により枠本体１９の開口が閉塞されて配線器具３３が枠本体１９内に収容不可能になったりするといった不具合がなくなる。
【００３２】
さらに、配線器具３３を壁材１３の表側に臨ませた状態で配線器具取付枠１１の開口を被覆する化粧プレートを壁材１３の表面に取り付けると、壁材１３の表面に配線器具３３が取り付けられる。
【００３３】
前記の第１実施形態によって発揮される効果について、以下に記載する。
・ビス保持部１４から取付ビス１５を取り外した後、ビス保持部１４を構成する保持部本体１４ａを枠本体１９から折り取り除去又は折り曲げ可能に構成した。従って、ビス保持部１４が枠本体１９内へ突設されたままの場合と異なり、配線器具取付枠１１に配線器具３３を収容して取り付けるとき、ビス保持部１４が配線器具３３に接触したり、収容の障害となったりするといった不具合をなくすことができ、配線器具取付枠１１への配線器具３３の取付作業を容易に行うことができる。
【００３４】
・ビス保持部１４を左内側壁２２内面における枠本体１９の前面側に設けることにより、そのビス保持部１４に保持された取付ビス１５を枠本体１９の前面側に配置した。そのため、ビス保持部１４が左外側壁２１の後端から突設され、取付ビス１５が枠本体１９の奥方に保持されている場合と異なり、手を枠本体１９内奥方まで挿入することなく取付ビス１５を指で容易に摘むことができ、ビス保持部１４から容易に取り外すことができる。
【００３５】
・保持部本体１４ａはその基端部の上下両端縁のみで左内側壁２２と連結されているため、保持部本体１４ａの基端部全体が左内側壁２２と連結されている場合と比較して保持部本体１４ａの折り取り又は折り曲げ作業を容易に行うことができる。従って、ビス保持部１４の枠本体１９からの除去作業又は折り曲げ作業を速やかに行うことができ、配線器具３３の配線器具取付枠１１への取付作業の短時間化を図ることができる。
【００３６】
・保持部本体１４ａが枠本体１９に残存するように金属板を打ち抜き除去することにより、枠本体１９は四角枠状に形成され、その保持部本体１４ａを切り起こして第１及び第２突片１４ｂ，１４ｃが形成されてビス保持部１４が構成されている。そのため、保持部本体１４ａを枠本体１９とは別に形成し、左内側壁２２に接着等により設ける場合と比較して配線器具取付枠１１の製造工程を簡易化することができる。
【００３７】
・ビス保持部１４は左内側壁２２内面において、枠本体１９の前端面から後退した位置より枠本体１９内方へ突設されている。そのため、ビス保持部１４と接触することなく穿孔ビット３８を内側壁２２内周面に沿って移動させることができる。従って、透孔３１穿設作業を円滑に行うことができるとともに、枠本体１９の開口に沿った透孔３１を壁材１３に穿設する作業を容易に行うことができる。
【００３８】
・ビス保持部１４の位置を確認し、そのビス保持部１４を避けながら切除工具３７ａ及び穿孔ビット３８を移動させる必要がなくなる。そのため、壁材１３表側から切除工具３７ａ及び穿孔ビット３８を内側壁２２内周面に沿って移動させればよく、透孔３１の穿設作業の簡易化を図ることができる。
【００３９】
（第２実施形態）
第２実施形態では、上記第１実施形態と異なる点について主に説明する。
図８に示す第２実施形態の配線器具取付枠１１のビス保持部１４について説明すると、ビス保持部１４は保持部本体１４ａを備えている。保持部本体１４ａは左内側壁２２の中央部下端縁から左内側壁２２の長さ方向に沿って所定幅有する状態で左外側壁２１側へ延び、さらに、枠本体１９の後面側へ所定長さ延びて形成されている。なお、保持部本体１４ａの基端部と左内側壁２２の下端縁との間には第１実施形態と同様に折り取り又は折り曲げ補助手段が構成されている。
【００４０】
第１及び第２突片１４ｂ，１４ｃはそれぞれ保持部本体１４ａを枠本体１９内方へ切り起こして形成され、第１及び第２突片１４ｂ，１４ｃの先端面はそれぞれ左内側壁２２の内面より外方へ後退した位置に配置されている。そして、ビス保持部１４は左内側壁２２内面より外面側へ後退した位置に設けられ、枠本体１９内へ突出しておらず、ビス保持部１４に保持された取付ビス１５も左内側壁２２内面から枠本体１９内へ突出していない。
【００４１】
配線器具取付枠１１の未使用時、ビス保持部１４は左内側壁２２の内面に沿った位置、即ち左内側壁２２内面の延長面から外方へ後退した位置に配置されている。そして、取付ビス１５をビス保持部１４から取外すとき、図８に２点鎖線に示すように、保持部本体１４ａの基端部と左内側壁２２との連結部分を折り曲げ中心として枠本体１９内方へ折り曲げることにより平面部分が枠本体１９の開口側に臨むように移動可能に構成されている。
【００４２】
また、ビス保持部１４を元の状態に戻すため、保持部本体１４ａと左内側壁２２との連結部分を中心にして保持部本体１４ａを後方へ折り曲げることによりビス保持部１４を枠本体１９の後面側へ移動可能に構成されている。なお、保持部本体１４ａの基端部と左内側壁２２との間を係合関係により係合するとともに、その係合部分を回動中心としてビス保持部１４を枠本体１９の開口側又は後面側へ移動可能に設けてもよい。
【００４３】
さて、第２実施形態の配線器具取付枠１１の使用方法は、まず、配線器具取付枠１１を壁材１３の裏側に配置し、穿孔ビット３８により枠本体１９の開口の内周形状に沿った透孔３１を穿設する。このとき、保持部本体１４ａは左内側壁２２内面の延長面から枠本体１９内方へ突出していないため、穿孔ビット３８がビス保持部１４に接触することなく内側壁２２内周面に案内され、配線器具取付枠１１の開口の内周形状に沿った形状をなす透孔３１が壁材１３に穿設される。
【００４４】
続いて、前記透孔３１から枠本体１９内へ手を挿入し、保持部本体１４ａを指で摘んで枠本体１９の内方へ移動させて開口側へ臨ませ、そのビス保持部１４に保持された取付ビス１５をそれぞれ指で摘んで取外す。
【００４５】
次に、保持部本体１４ａを枠本体１９から折り取り除去する。又は保持部本体１４ａを枠本体１９の後面側、即ち左外側壁２１側へ回動させて、左内側壁２２内面の延長面から外方へ後退した位置に再度配置してもよい。そして、以下、第１実施形態と同様に取付ビス１５を使用して配線器具３３の配線器具取付枠１１への取付作業が行われる。
【００４６】
従って、第２実施形態の配線器具取付枠１１によれば、保持部本体１４ａは左内側壁２２内面より同左内側壁２２の外面側へ後退した位置に設けられ、枠本体１９内方へ突出していない。そのため、壁材１３に透孔３１を穿設する際、穿孔ビット３８を枠本体１９奥方まで挿入してもビス保持部１４に接触するのが防止されて配線器具取付枠１１の開口の内周形状に沿った形状をなす透孔３１を壁材１３に確実かつ容易に穿設することができる。
【００４７】
なお、本実施形態は、次のように変更して具体化することも可能である。
・図９に示すビス保持部１４を備えた配線器具取付枠１１としてもよい。ビス保持部１４は保持部本体１４ａを備え、その保持部本体１４ａは左内側壁２２の中央部下端縁から左内側壁２２の長さ方向に沿って所定幅有する状態で枠本体１９の後面側へ所定長さ延びて形成されている。第１及び第２突片１４ｂ，１４ｃはそれぞれ保持部本体１４ａを枠本体１９外方、即ち左外側壁２１側へ切り起こして形成され、ビス保持部１４に保持された取付ビス１５も枠本体１９の左内側壁２２の外面に保持されている。そして、左内側壁２２の内面は面一に形成されている。
【００４８】
配線器具取付枠１１の未使用時、ビス保持部１４はその裏面が左内側壁２２として枠本体１９内に配置されている。そして、取付ビス１５をビス保持部１４から取外すとき、図９に２点鎖線に示すように、保持部本体１４ａの基端部と左内側壁２２との間の連結部分を折り曲げ中心として枠本体１９内方へ１８０度回動させることにより第１及び第２突片１４ｂ，１４ｃが枠本体１９内方へ突設する状態に配置され、取付ビス１５が枠本体１９内に配置されるように構成されている。なお、保持部本体１４ａの基端部と左内側壁２２との間を係合関係により係合するとともに、その係合部分を回動中心としてビス保持部１４を枠本体１９の開口側又は後面側へ移動可能に設けてもよい。
【００４９】
なお、取付ビス１５をビス保持部１４から取り外した後、保持部本体１４ａを枠本体１９から折り取って除去してもよく、保持部本体１４ａを枠本体１９の後面側へ回動させて左内側壁２２の内面に沿った位置に配置してもよい。
【００５０】
従って、壁材１３に透孔３１を穿設するとき、第１及び第２突片１４ｂ，１４ｃ及び取付ビス１５は左内側壁２２の外面に配置されているため、穿孔ビット３８を枠本体１９奥方まで挿入してもビス保持部１４に接触することがなく配線器具取付枠１１の開口の内周形状に沿った形状をなす透孔３１を壁材１３に確実かつ容易に穿設することができる。
【００５１】
・図１０に示すビス保持部１４を備えた配線器具取付枠１１としてもよい。ビス保持部１４は、枠本体１９と別部材により構成されているとともに、枠本体１９に対して着脱可能に設けられている。図１１に示すように、ビス保持部１４を構成する保持部本体１４ａは四角板状をなし、その相対向する上下両外端面の一端部からはそれぞれ回動機構を構成する係合突起３５が外方へ突設されている。一方、左内側壁２２の中央部下端面には所定間隔をおいて一対の軸受け３６が回動機構として突設され、各軸受け３６にはそれぞれ前記係合突起３５が係合可能な係合孔３６ａが形成されて回動機構が形成されている。
【００５２】
そして、図１０に示すように、前記各係合突起３５がそれぞれ係合孔３６ａに係合されて保持部本体１４ａは左内側壁２２、即ち枠本体１９に対して回動可能に取り付けられている。ビス保持部１４が枠本体１９に取り付けられた状態において、保持部本体１４ａを枠本体１９の前面側へ回動させることにより、各取付ビス１５を枠本体１９の前面側に配置可能に構成されている。
【００５３】
従って、図１１に示すように、ビス保持部１４は係合突起３５と係合孔３６ａとの係合を解除することにより枠本体１９から除去することができるため、ビス保持部１４を左内側壁２２から折り取る場合と比較してビス保持部１４の除去作業の簡易化を図ることができ、配線器具３３の配線器具取付枠１１への取付作業の短時間化を図ることができる。
【００５４】
・図１２に示すように、枠本体１９の周壁としての上下両内側壁２２の中央部下端から配線器具取付部２８を介して保持部本体１４ａを延設する。図１３に示すように、保持部本体１４ａの基端側の後面に第１及び第２突片１４ｂ，１４ｃを切り起こし形成してビス保持部１４を形成するとともに、それら第１及び第２突片１４ｂ，１４ｃにより保持部本体１４ａの後面に取付ビス１５を保持させてもよい。なお、保持部本体１４ａの基端部と配線器具取付部２８の外面とは２箇所で連結されている。また、保持部本体１４ａの先端側前面に磁石保持突片１８を３箇所に切り起こし、その磁石保持突片１８の間に磁石１８ａが保持されている。
【００５５】

Next, the perforation bit 38 is moved along the inner peripheral surface of the inner side wall 22, and the wall material 13 is cut off by the perforation bit 38. At this time, as shown in FIG. 5, the holding portion main body 14a is protruded into the frame main body 19 from a position retracted from the front end surface of the left inner wall 22. Therefore, when the piercing bit 38 moves, the piercing bit 38 is prevented from contacting the screw holding portion 14. Then, by cutting off the wall material 13 of the drill bit 38, as shown in FIG. 6, a through hole 31 having a shape along the inner peripheral shape of the opening of the wiring device mounting frame 11 is formed in the wall material 13. The opening of the main body 19 faces the front side of the wall material 13.
[0029]
Subsequently, a hand is inserted into the frame main body 19 through the through hole 31, and the mounting screws 15 held by the screw holding portions 14 are pinched and removed with fingers. At this time, since the screw holding portion 14, that is, the mounting screw 15 is arranged on the front side of the frame main body 19, the mounting screw 15 can be picked up with a finger without inserting a hand deep into the frame main body 19. .
[0030]
After each of the pair of mounting screws 15 is removed from the screw holding portion 14, the holding portion main body 14 a is gripped with a finger, and the work of bending the holding portion main body 14 a in the front-rear direction is repeated to be cut off from the frame body 19. At this time, since the holding portion main body 14a is connected to the left inner wall 22 only at the upper and lower ends of the base end, the above-mentioned folding operation is easily performed. It is to be noted that the holding portion main body 14a is not separated from the frame main body 19, but is bent rearward around the connecting portion between the left inner wall 22 and the base end of the holding portion main body 14a to be moved to the rear surface side of the frame main body 19.

At this time, since the screw holding portion 14 has been removed from the inside of the frame main body 19, when the wiring device 33 is accommodated inside the frame main body 19, the wiring device 33 comes into contact with the screw holding portion 14, This eliminates the problem that the opening of the frame main body 19 is closed and the wiring device 33 cannot be housed in the frame main body 19.
[0032]
Furthermore, when the decorative plate for covering the opening of the wiring device mounting frame 11 is mounted on the surface of the wall material 13 with the wiring device 33 facing the front side of the wall material 13, the wiring device 33 is mounted on the surface of the wall material 13. Can be
[0033]
The effects exerted by the first embodiment will be described below.
After the mounting screw 15 has been removed from the screw holding portion 14, the holding portion main body 14a constituting the screw holding portion 14 can be cut off from the frame main body 19 or can be bent. Therefore, unlike the case where the screw holding portion 14 is kept protruding into the frame main body 19, when the wiring device 33 is housed and mounted on the wiring device mounting frame 11, the screw holding portion 14 may come into contact with the wiring device 33. In addition, it is possible to eliminate problems such as an obstacle to accommodation, and to easily perform the work of attaching the wiring device 33 to the wiring device mounting frame 11.
[0034]
The mounting screw 15 held by the screw holding portion 14 is disposed on the front side of the frame main body 19 by providing the screw holding portion 14 on the front side of the frame main body 19 on the inner surface of the left inner side wall 22. Therefore, unlike the case where the screw holding portion 14 is protruded from the rear end of the left outer wall 21 and the mounting screw 15 is held at the back of the frame main body 19, the screw is not attached to the inside of the frame main body 19 without being inserted. The screw 15 can be easily picked with a finger, and can be easily removed from the screw holding portion 14.
[0035]
Since the holding portion main body 14a is connected to the left inner wall 22 only at the upper and lower ends of the base end thereof, it is compared with the case where the entire base end of the holding portion main body 14a is connected to the left inner wall 22. Thus, the work of folding or bending the holding portion main body 14a can be easily performed. Therefore, the work of removing or bending the screw holding portion 14 from the frame main body 19 can be performed quickly, and the work of attaching the wiring device 33 to the wiring device mounting frame 11 can be shortened.
[0036]
The frame body 19 is formed in a rectangular frame shape by punching and removing the metal plate so that the holding portion main body 14a remains in the frame body 19, and the holding portion main body 14a is cut and raised to form the first and second protrusions. The screw holding portion 14 is formed by forming 14b and 14c. Therefore, the manufacturing process of the wiring device mounting frame 11 can be simplified as compared with a case where the holding portion main body 14a is formed separately from the frame main body 19 and provided on the left inner side wall 22 by bonding or the like.
[0037]
The screw holding portion 14 is provided on the inner surface of the left inner side wall 22 so as to protrude into the frame main body 19 from a position retracted from the front end surface of the frame main body 19. Therefore, the drill bit 38 can be moved along the inner peripheral surface of the inner wall 22 without contacting the screw holding portion 14. Therefore, the work of drilling the through hole 31 can be performed smoothly, and the work of drilling the through hole 31 along the opening of the frame body 19 in the wall member 13 can be easily performed.
[0038]
It is not necessary to check the position of the screw holding portion 14 and move the cutting tool 37a and the drill bit 38 while avoiding the screw holding portion 14. Therefore, the cutting tool 37a and the drill bit 38 need only be moved along the inner peripheral surface of the inner wall 22 from the front side of the wall material 13, and the work of drilling the through-hole 31 can be simplified.
[0039]
(2nd Embodiment)
In the second embodiment, differences from the first embodiment will be mainly described.
The screw holding portion 14 of the wiring device mounting frame 11 according to the second embodiment shown in FIG. 8 will be described. The screw holding portion 14 includes a holding portion main body 14a. The holding portion main body 14a extends from the lower end edge of the central portion of the left inner wall 22 to the left outer wall 21 with a predetermined width along the length direction of the left inner wall 22, and further has a predetermined length toward the rear side of the frame main body 19. It is formed to extend. In addition, between the base end portion of the holding portion main body 14a and the lower end edge of the left inner wall 22, a folding or bending assisting means is configured as in the first embodiment.
[0040]
The first and second protruding pieces 14b and 14c are formed by cutting and raising the holding portion main body 14a into the frame main body 19, respectively, and the distal end faces of the first and second protruding pieces 14b and 14c are respectively formed on the inner surface of the left inner wall 22. It is located at a position further retracted outward. The screw holding portion 14 is provided at a position retracted to the outer surface side from the inner surface of the left inner wall 22, does not protrude into the frame body 19, and the mounting screw 15 held by the screw holding portion 14 also has the inner surface of the left inner wall 22. Does not protrude into the frame body 19.
[0041]
When the wiring device mounting frame 11 is not used, the screw holding portion 14 is disposed at a position along the inner surface of the left inner wall 22, that is, at a position retracted outward from an extension of the inner surface of the left inner wall 22. Then, when the mounting screw 15 is removed from the screw holding portion 14, as shown by a two-dot chain line in FIG. 8, the connection portion between the base end portion of the holding portion main body 14a and the left inner wall 22 is bent around the inside of the frame main body 19.
