Description

【０００１】
【発明の属する技術分野】
本発明は、壁パネルを用いた配線システムに関するものである。
【０００２】
【従来の技術】
一般的に、集合住宅や戸建て住宅などの住戸で採用している配線システムでは、住戸内に配設する電灯、スイッチ、コンセントなどに接続される電線や、電話、インターホン、テレビ共聴機器などに接続される通信線などの配線の殆どが二重天井内や壁パネル内に敷設されている。
【０００３】
ところで配線を壁パネルを用いて行うものとしては、天井側から壁パネル内に立ち下げられた電線と壁パネルの表面側に取り付けられた埋込型の配線器具（例えば、スイッチ、コンセントなど）に接続した配線（器具側配線）とを接続するためのコネクタ装置を壁パネルの天井側端部に近い天井裏に配設した配線システムがある。（例えば、特許文献１参照）
或いは壁パネルにおいて天井に比較的近い部分の内側に接続装置を配設したものがある。（例えば、特許文献２参照）
【０００４】
【特許文献１】
特開平１１−３２４１７号公報（図１）
【特許文献２】
実開平７−３６５３５号公報（第６頁−第７頁、図１、図２）
【０００５】
【発明が解決しようとする課題】
ところで、電力会社の規定する内線規定や、電気設備技術基準によれば、上記電線と器具側の配線とを接続するコネクタ装置の配設位置には点検窓を設ける必要があるので、特許文献１に記載の構成では、壁パネルの天井側端部付近の天井に点検窓を設ける必要があり、また特許文献２に記載の構成では、壁パネルの天井側端部に近い部分に点検窓を設ける必要がある。
【０００６】
そのため、配線設備用の壁パネルが複数同一室内に用いられると、夫々に対応する点検窓が室内に露出することになり、室内の雰囲気が損なわれてしまうという不具合があった。また、接続装置を点検するための点検窓が天井或いは壁パネルにおいて天井に比較的近い部分に設けられているので、点検に手間が係るという問題があった。
【０００７】
本発明は上記事由に鑑みて為されたものであり、その目的するところは、点検窓によって室内の雰囲気が損なわれることがなく、しかもコネクタ装置の点検が容易な壁パネル用配線システムを提供することにある。
【０００８】
【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、表裏の２枚のパネル板との間に内部空間を形成した壁パネルを用い、該壁パネルの天井側端部に設けた設けた電線導入用開口部から、天井裏に配線されている電力線を上記内部空間に導入し、壁パネルのパネル板側に設けた取付窓に室内側から取り外し自在に埋込型配線器具を取り外し自在に取り付け、前記配線器具に接続される器具側配線と上記電力線側との接続を行うコネクタ装置の位置を上記取付窓近傍の上記内部空間としたことを特徴とする。
【０００９】
請求項２の発明では、請求項１の発明において、上記壁パネルの取付窓の近傍のパネル板裏面に中継用ジョイントボックスを配設し、該中継用ジョイントボックスに上記電力線の一端を接続するとともに該電力線の一端と電気的に接続された接続用電線と、上記器具側配線とを上記コネクタ装置により着脱自在に接続したことを特徴とする。
【００１０】
請求項３の発明では、請求項２の発明において、裏面側に上記中継用ジョイントボックスを取り付けるとともに、表裏に貫通する上記取付窓を開口した配線ボードを取り付ける開口部を、上記壁パネルの表側パネル板に形成していることを特徴とする。
【００１１】
請求項４の発明では、請求項１乃至３の何れかの発明において、上側部及び下側部の双方を背面側に屈曲するための屈曲部を左側部及び右側部に夫々有する枠状に形成され、前記上側部及び下側部には、夫々背面側から上下方向に前記壁の背面と当接するフランジ部が立設され、前記左側部及び右側部には、夫々正面側から左右方向に前記壁の正面と当接するフランジ部が立設されている保持枠を上記壁パネルの取付窓に取り付けるとともに、該保持枠に配線器具を取り付けた取付枠を着脱自在に取り付けていることを特徴とする。
【００１２】
請求項５の発明では、請求項１乃至４の何れかの発明において、上記壁パネルは高さ寸法及び横幅寸法が規格化された他の壁パネルと連接されて壁を構成するものであって、横幅寸法が規格化された横幅の単位寸法の整数倍若しくは整数分の１倍で形成されていることを特徴とする。
【００１３】
【発明の実施の形態】
以下本発明を実施形態により説明する。
【００１４】
（実施形態１）
図１は本実施形態の配線設備用壁パネル１を用いて間仕切り壁を構成した例を示しており、図示するように床Ｆ上には配線システム用の壁パネル１、更に間仕切り用の壁パネル２…を連接するように立設するとともに、天井側端部を二重天井の室内側天井パネル（図示せず）に接するように配設することで、間仕切り壁を構成している。
【００１５】
ここで壁パネル１は、例えば両側及び上下に枠材３…を配置した枠体表裏にパネル板４，４を配設して構成されるもので、図２に示すように表裏のパネル板４，４の間には内部空間６が形成され、この内部空間６を配線スペースとして用いるもので、天井端部側には天井裏に配線された電線（電力線）を内部空間６に垂下させるための電線導入用開口部７を設けてある。そして電線導入用開口部７の下方において、室内側となる表側のパネル板４の所定高さ位置（壁スイッチに適正な床からの２高さ位置ａと、コンセントに適正な床Ｆからの高さ位置ｂ）とに埋込型配線器具取り付け用の取付窓８ａ、８ｂを夫々開口してある。
【００１６】
この取付窓８ａ、８ｂには配線器具を着脱自在に取り付けた取付枠（図示せず）が挟み金具（図示せず）でパネル板４を挟持させることで取り外し自在に取り付けたり、或いはパネル板４に直接木ねじで取り外し自在に取り付けるようになっている。この施工方法は周知の方法であるの説明は省略する。
【００１７】
そして取付枠に取り付けられた配線器具の後部は壁パネル１内に収められ、前部が室内側に臨む。そして中央に配線器具の前部を露出させる窓を設けた化粧プレート９を取付枠の前部側に取り付けることで、取付窓８ａ、８ｂの開口及び取付枠を被蔽するようになっている。
【００１８】
さて本実施形態では壁パネル１に取り付けるコンセントからなる配線器具１２とスイッチからなる配線器具１３とに対応するように図１で示すように二重天井の電気設備の収納室１０の天井裏に配線ボックス２２から夫々に対応する電力線Ｌ１、Ｌ１’を導出しており、一方の電力線ｌは直接壁パネル１の電線導入開口７から内部空間６へ直接導入され、その先端を取付窓８ｂ付近まで内部空間６内を垂下させている。また他方の電力線Ｌ１’を天井裏に配置しているモールディングユニット２１に接続している。
【００１９】
またモールディングユニット２１は、スイッチからなる配線器具１２を介して照明器具２０の配線Ｌ２に電力線Ｌ１’を接続するためのもので、このモールディングユニット２１からはスイッチ側に接続する電力線Ｌ３を導出しており、この電力線Ｌ５は壁パネル１の電線挿入導入口７から内部空間６に導入され、その先端を取付窓８ａ近傍へ垂下させている。
【００２０】
ここで取付窓８ａにはスイッチからなる配線器具１２を取り付けている取付枠が上述のように取り付けられるのであるが、配線器具１２の裏面の接続端子（図示せず）に接続した器具側配線Ｌ４の先端にはコネクタ装置１１の被接続具を予め取り付けており、近傍位置に存在する電力線Ｌ３の先端に取り付けたコネクタ装置１１の接続具が接続される。
【００２１】
また取付窓８ｂにはコンセントからなる配線器具１３を取り付けている取付枠が上述のように取り付けられるのであるが、配線器具１３の裏面の接続端子（図示せず）に接続した器具側配線Ｌ５の先端にはコネクタ装置１１の被接続具を予め取り付けており、近傍位置に存在する電力線Ｌ１の先端に取り付けたコネクタ装置１１の接続具が接続される。
【００２２】
而して施工に当たっては取付窓８ａ、８ｂから取付枠毎、配線器具１２、１３を夫々取り外している状態で取付窓８ａ，８ｂ近傍に垂下している上記電力線Ｌ３，Ｌ１の接続具に取付窓８ａ，８ｂを介して器具側配線Ｌ４，Ｌ５の被接続具を接続して電力線Ｌ１、Ｌ３と器具側配線Ｌ４、Ｌ５とを電気的に接続するのである。
【００２３】
そしてこの接続後、配線器具１２、１３を取り付けている夫々の取付枠を対対応する取付窓８ａ，８ｂに取り付け、化粧プレート９を取付枠に装着すれば配線器具１２、１３の設置と配線とが完了する。
【００２４】
さて上述したように電力会社の規定する内線規定や、電気設備技術基準によれば、上記電線と器具側の配線とを接続するコネクタ装置の配設位置には点検窓を設ける必要があるが、本実施形態では、上記取付窓８ａ、８ｂの近傍にコネクタ装置１１が位置するため、配線器具１２，１３を取付枠とともに取り外すことで、取付窓８ａ、８ｂからコネクタ装置１１の点検することができる。つまり電力会社の内線規定や電気設備技術基準を満足できる点検窓として配線器具１２，１３の取付窓８ａ、８ｂを兼ねた壁パネル１による配線システムを構築できるのである。
【００２５】
尚本実施形態に用いる壁パネル１は、他の間仕切り用壁パネル２とともに寸法が規格されており、間仕切り用壁パネル２の標準の横幅寸法（例えば９００ｍｍ）を単位寸法とした場合に、その１／３（３００ｍｍ）、２／３（６００ｍｍ）と言うように整数倍分の１の寸法若しくはその整数倍の寸法のものが準備され、部屋の大きさなどによって適宜な横幅寸法のものが選択使用されるようになっている。
【００２６】
（実施形態２）
上記実施形態１では壁パネル１に直接配設器具取付用の取付窓８ａ、８ｂを開口させているが、図３に示すに示すように取付窓８ａ、８ｂを夫々開口させている配線ボード１４ａ、１４ｂを用いて、この配線ボード１４ａ、１４ｂを壁パネル１のパネル板４に形成した開口部４０（図４参照）に嵌め込むように取り付けるようにしても良い。
【００２７】
つまり配線ボード１４ａ（又は１４ｂ）には図５（ａ）（ｂ）及び図６に示すように取付窓８ａ（又は８ｂ）の開口位置に隣接する配線ボード１４ａ（又は１４ｂ）の裏面に中継用ジョイントボックス１５を配置し、壁パネル１の内部空間６に上述のように垂下させた電力線Ｌ１，Ｌ３の先端をジョイントボックス１５に接続し、このジョイントボックス１５にコネクタ装置１１の接続具を設け、配線器具１２，１３からの器具側配線Ｌ４、Ｌ５のコネクタ装置１１の被接続具を接続するようになっている。
【００２８】
本実施形態の場合、配線施工に当たっては予め配線ボード１４ａ、１４ｂ側の取付窓８ａ、８ｂに配線器具１２，１３を上述と同様に取付枠を用いて取り付け、ジョイントボックス１５に対して電力線Ｌ１や、Ｌ３を接続するとともに配線器具１２、１３の器具側配線Ｌ４、Ｌ５のコネクタ装置１１の被接続具をジョイントボックス１５側のコネクタ装置１５の接続具に接続する。そして接続終了後配線ボード１４ａ、１４ｂを夫々に対応するパネル板４の開口部４０に螺子固定すれば施工完了となる。
【００２９】
さて上述したように電力会社の規定する内線規定や、電気設備技術基準によれば、上記電線と器具側の配線とを接続するコネクタ装置の配設位置には点検窓を設ける必要があるが、本実施形態の場合も、上記取付窓８ａ、８ｂの近傍にジョイントボックス１５のコネクタ装置１１が位置するため、配線器具１２，１３を取付枠とともに取付窓８ａ、８ｂから取り外すことで、取付窓８ａ、８ｂからコネクタ装置１１の点検することができる。つまり電力会社の内線規定や電気設備技術基準を満足できる点検窓として配線ボード１４ａ、１４ｂの取付窓８ａ、８ｂが兼ねることになる。
【００３０】
尚本実施形態に用いる壁パネル１も実施形態１と同様に規格化された横幅寸法に形成されたものが準備される。
【００３１】
（実施形態３）
上記実施形態１，２の何れも配線器具１２，１３を取り付けた取付枠を取付窓８ａ、８ｂに取り付ける方法としては挟み金具や木ねじが用いられているが、本実施形態では図７に示すような保持枠３０と、図８に示すような取付枠４０とを用いることで取付窓８ａ、８ｂへの取付枠４０の取り付けを容易にしている。
【００３２】
先ず、図８を用いて取付枠４０について説明する。
【００３３】
図８に示す取付枠４０は、当該取付枠４０を後述の保持枠３０に保持するための先端に外向きの爪４１０ａ，４２０ａを持つ係合突片４１０，４２０がそれぞれ背面側に立設された上側部４１及び下側部４２と、いわゆる１個モジュール寸法の配線器具を最大で３個取り付けることができるようにするための複数の係止孔（図示せず）がそれぞれ形成された左側部４３及び右側部４４とを一体に有する枠状に形成されている。
【００３４】
また、上側部４１及び下側部４２には、従来と同様に、壁の取付孔の奥側に挟み金具などに螺子止めするための小判状の螺子挿通孔２１１，２２１がそれぞれ係合突片４１０，４２０の近傍に形成されている他、それら螺子挿通孔２１１，２２１の各両側に、化粧プレート９を取り付けるための取付孔（図５参照）が形成されている。
【００３５】
要するに、取付枠４０は、爪４１０ａ，４２０ａを持つ係合突片４１０，４２０がそれぞれ上側部４１及び下側部４２の背面側に立設されている以外は例えば従来の樹脂製の取付枠と同様に構成されるのであり、このため、更に詳細な説明は省略する。
【００３６】
次に、図７を用いて保持枠３０について説明する。保持枠３０は、図９に示すように壁パネル１のパネル板４に形成された取付窓８の位置でそのパネル板４に取り付けられ、その取付窓８内に埋め込まれる例えばコンセントのような配線器具１３を取り付けるための取付枠４０を保持するものであり、樹脂により、上側部３１及び上側部３２の双方を背面側に屈曲するための屈曲点３３１，３４１を左側部３３及び右側部３４にそれぞれ有する枠状に形成されている。第１実施形態では、保持枠３０は、柔軟な樹脂製であって、左側部３３及び右側部３４の中央部に、それぞれ背面側に開口する三角形状の切欠部３３２、３４２が形成され、それら切欠部３３２、３４２の頂点側がそれぞれ上記屈曲点３３１，３４１となっている。
【００３７】
そして、上側部３１及び上側部３２には、それぞれ背面側から上下方向にパネル板４の背面と当接（近接）するフランジ部３１０，３２０が立設されいる。一方、左側部３３及び右側部３４の上下端側には、それぞれ正面側から左右方向にパネル板４の正面と当接（近接）するフランジ部３３０，３４０が立設されている。
【００３８】
また、上側部３１及び上側部３２には、取付枠４０の係合突片４１０，４２０と互いに係合する係合部３１１、３２１がそれぞれ設けられている。これら係合部３１１、３２１は、内周面の正面側（図７（ｂ）では右側）に、背面側（同図では左側）ほど高さが高くなりその終端で段差が生じるテーパ状に形成され、係合突片４１０，４２０の先端の爪４１０ａ，４２０ａにそのテーパ状の部分を乗り越えさせてそれらの爪４１０ａ，４２０ａを段差面３１１ａ，３２１ａにそれぞれ係止させる。
【００３９】
また、上側部３１、上側部３２、左側部３３及び右側部３４には、それぞれパネル板４の取付窓８により強く嵌合するための嵌合用ばね部３１３，３２３，３３３，３４３が形成されている。これらのうち、嵌合用ばね部３１３，３２３は、それぞれフランジ部３１０，３２０から正面側に向かって外側に傾斜しながら立設された状態になっている。他方、嵌合用ばね部３３３，３４３は、各周囲が切り欠かれており、背面側から正面側に向かって外側に傾斜しながら立設された状態になっている。
【００４０】
更に、左側部３３及び右側部３４には、それぞれ保持枠３０をパネル板４に固定するための固定爪３３４，３４４が背面側における切欠部３３２、３４２の両側に形成されている。それら固定爪３３４，３４４は、正面側ほど高さが高くなりその終端で段差が生じるテーパ状に形成され、パネル板４の取付窓８の厚み部分をそのテーパ状の部分が乗り越えてそれらの段差面３３４ａ，３４４ａがパネル板４の背面にそれぞれ係止する構造になっている。
【００４１】
このような構造の保持枠３０及び取付枠４０の組付手順について説明すると、先ず、図９（ａ），（ｂ）に示すように、保持枠３０の上側部３１及び上側部３２の双方を背面側に屈曲し、この状態で、図９（ｃ）に示すように、上側部３１及び上側部３２をパネル板４の取付窓８の奥に挿入する。
【００４２】
続いて、保持枠３０の屈曲点３３１，３４１側を押すなどしながら、図９（ｄ），（ｅ）に示すように、フランジ部３１０，３２０がパネル板４の背面側に潜り込むように、固定爪３３４，３４４の段差面３３４ａ，３４４ａがパネル板４の背面にそれぞれ係止するまで固定爪３３４，３４４側を押し込んで、背面側に屈曲した上側部３１及び上側部３２を元の状態に戻す。これにより、パネル板４への保持枠３０の取り付けが完了する。
【００４３】
この後、図１０（ａ）〜（ｄ）に示すように、取付窓８の位置でパネル板４に取り付けられた保持枠３０内に、結線済みの配線器具１３が取り付けられた取付枠４０の係合突片４１０，４２０を所定位置に収めるようにして挿入する。このとき、係合突片４１０，４２０の爪４１０ａ，４２０ａが、それぞれ保持枠３０の係合部３１１、３２１を乗り越えて段差面３１１ａ，３２１ａに係止する。これにより、取付枠４０がパネル板４に取り付けられた保持枠３０に保持される（図３）。そして、この後は、図１０（ｅ）〜（ｆ）に示すように、従来と同様にして、化粧プレート９を取付枠４０に取着する。
【００４４】
ところで、保持枠３０は上下左右対称な形状をしているので、上側部３１と上側部３２とを逆にしても、上記と全く同様にして使用することができることは言うまでもない。
【００４５】
以上の保持枠３０によれば、工事時間の短縮、工事費削減、配線器具取付精度・強度の向上、配線器具の移設／増設作業の省略化などが可能となる。
【００４６】
具体的には、保持枠３０が、上側部３１及び上側部３２の双方を背面側に屈曲するための屈曲点３３１，３４１を左側部３３及び右側部３４にそれぞれ有する枠状に形成されるので、上側部３１及び上側部３２の双方を背面側に屈曲した状態で、上側部３１及び上側部３２側をパネル板４の取付窓８の奥に挿入し、背面側に屈曲した上側部３１及び上側部３２を元の状態に戻すことにより、工具を使用することなく、しかも極めて簡単に保持枠３０をパネル板４の取付窓８に取り付けることができる。また、上側部３１及び上側部３２には、それぞれ背面側から上下方向にパネル板４の背面と当接するフランジ部３１０，３２０が立設され、左側部３３及び右側部３４には、それぞれ正面側から左右方向にパネル板４の正面と当接するフランジ部３３０，３４０が立設されているので、正面側への脱落をフランジ部３１０，３２０で防止し、取付窓８の奥側への脱落をフランジ部３３０，３４０で防止することができる。また、上記と逆の手順によりパネル板４の取付窓８から保持枠３０を取り外すことも可能である。
【００４７】
また、保持枠３０には、背面側ほど高さが高くなりその終端で段差の生じるテーパ状の係合部３１１、３２１が上側部３１及び上側部３２の内周面の正面側に形成されている一方、取付枠４０には、背面側に立設され先端に外向きの爪４１０ａ，４２０ａを持つ係合突片４１０，４２０が係合部３１１、３２１に対応するように設けられているので、取付窓８の位置でパネル板４に取り付けられた保持枠３０内に、取付枠４０の係合突片４１０，４２０を収めるようにして挿入することにより、係合突片４１０，４２０の爪４１０ａ，４２０ａが、保持枠３０の係合部３１１、３２１を乗り越えて、段差面３１１ａ，３２１ａに係止するので、工具を使用することなく、しかも係合突片４１０，４２０に過渡的な負荷を係ることなく極めて簡単に取付枠４０を保持枠３０に保持させることができる。
【００４８】
このように構成することで取付枠４０の取付を容易にしている。尚その他の構成は実施形態１又は２の構成を採用すれば良いので説明及び図示は省略する。
【００４９】
【発明の効果】
請求項１の発明は、表裏の２枚のパネル板との間に内部空間を形成した壁パネルを用い、該壁パネルの天井側端部に設けた設けた電線導入用開口部から、天井裏に配線されている電力線を上記内部空間に導入し、壁パネルのパネル板側に設けた取付窓に室内側から取り外し自在に埋込型配線器具を取り外し自在に取り付け、前記配線器具に接続される器具側配線と上記電力線側との接続を行うコネクタ装置の位置を上記取付窓近傍の上記内部空間としたので、コネクタ装置の配置部位に電力会社の内線規定や、電気設備技術基準により必要とされる点検窓を、配線器具の取付窓で兼用させることができ、そのため従来のように各壁パネルに対応して天井部に点検窓を設けたり、壁パネルの天井端部付近のパネル板に点検窓を設ける必要が無くなり、室内の美観を損ねることがなく、しかも配線器具の取付窓を点検窓とするので、点検作業の位置も背丈範囲に収まり、作業性も向上する。
【００５０】
請求項２の発明は、請求項１の発明において、上記壁パネルの取付窓の近傍のパネル板裏面に中継用ジョイントボックスを配設し、該中継用ジョイントボックスに上記電力線の一端を接続するとともに該電力線の一端と電気的に接続された接続用電線と、上記器具側配線とを上記コネクタ装置により着脱自在に接続したので、壁パネル内に導入した電力線の配線をジョイントボックスに対して行うことで、配線器具の器具側配線の接続の施工性を良くすることができる。
【００５１】
請求項３の発明は、請求項２の発明において、裏面側に上記中継用ジョイントボックスを取り付けるとともに、表裏に貫通する上記取付窓を開口した配線ボードを取り付ける開口部を、上記壁パネルの表側パネル板に形成しているので、配線ボードを壁パネルから外した状態で取付枠の取付やジョイントボックスへの接続が行えるため、一層施工性を高めることができる。
【００５２】
請求項４の発明は、請求項１乃至３の何れかの発明において、上側部及び下側部の双方を背面側に屈曲するための屈曲部を左側部及び右側部に夫々有する枠状に形成され、前記上側部及び下側部には、夫々背面側から上下方向に前記壁の背面と当接するフランジ部が立設され、前記左側部及び右側部には、夫々正面側から左右方向に前記壁の正面と当接するフランジ部が立設されている保持枠を上記壁パネルの取付窓に取り付けるとともに、該保持枠に配線器具を取り付けた取付枠を着脱自在に取り付けているので、配線器具を壁パネルへ取り付ける作業を一層容易にすることができる。
【００５３】
請求項５の発明は、請求項１乃至４の何れかの発明において、上記壁パネルは高さ寸法及び横幅寸法が規格化された他の壁パネルと連接されて壁を構成するものであって、横幅寸法が規格化された横幅の単位寸法の整数倍若しくは整数分の１倍で形成されているので、室内の間仕切り壁を構築する場合に、配線システムに用いない壁パネルとの整合性が良くなり、間仕切り壁などを構築する際の作業性を向上させることができる。

Thereby, the attachment frame 40 is held by the holding frame 30 attached to the panel plate 4 (FIG. 3). Then, as shown in FIGS. 10E to 10F, the decorative plate 9 is attached to the mounting frame 40 in the same manner as in the related art.
[0044]
By the way, since the holding frame 30 has a shape that is symmetrical in the vertical and horizontal directions, it is needless to say that the upper frame 31 and the upper frame 32 can be used in exactly the same manner even when the upper frame 32 is reversed.
[0045]
According to the holding frame 30 described above, it is possible to shorten the construction time, reduce the construction cost, improve the mounting accuracy and strength of the wiring equipment, and omit the work of relocating / extending the wiring equipment.
[0046]
Specifically, the holding frame 30 is formed in a frame shape having bending points 331 and 341 for bending both the upper part 31 and the upper part 32 to the rear side in the left part 33 and the right part 34, respectively. In a state where both the upper part 31 and the upper part 32 are bent to the rear side, the upper part 31 and the upper part 32 are inserted into the back of the mounting window 8 of the panel plate 4, and the upper part 31 bent to the rear side By returning the upper portion 32 to the original state, the holding frame 30 can be mounted on the mounting window 8 of the panel plate 4 extremely easily without using a tool. The upper part 31 and the upper part 32 are provided with upright flange parts 310 and 320, respectively, which come into contact with the back surface of the panel plate 4 in the vertical direction from the back side, and the left part 33 and the right part 34 respectively have the front side. Since the flange portions 330 and 340 that abut on the front surface of the panel plate 4 are provided upright in the left-right direction, the flange portions 310 and 320 prevent the front panel from falling off, and prevent the mounting window 8 from falling behind. This can be prevented by the flange portions 330 and 340. Further, it is also possible to remove the holding frame 30 from the mounting window 8 of the panel plate 4 in a procedure reverse to the above.
[0047]
The holding frame 30 has tapered engagement portions 311 and 321 formed on the front side of the inner peripheral surfaces of the upper portion 31 and the upper portion 32. On the other hand, the mounting frame 40 is provided with engaging projections 410, 420 erected on the back side and having outwardly extending claws 410 a, 420 a at the ends so as to correspond to the engaging portions 311, 321. By inserting the engaging protrusions 410 and 420 of the mounting frame 40 into the holding frame 30 mounted on the panel plate 4 at the position of the mounting window 8, the claws of the engaging protrusions 410 and 420 are inserted. Since the engagement portions 410a and 420a move over the engagement portions 311 and 321 of the holding frame 30 and are locked to the step surfaces 311a and 321a, a transient load is applied to the engagement protrusions 410 and 420 without using a tool. Extremely simple The mounting frame 40 can be held by the holding frame 30.
[0048]
With this configuration, attachment of the attachment frame 40 is facilitated. Note that other configurations may employ the configuration of the first or second embodiment, and thus description and illustration are omitted.
