【０００１】
【発明の属する技術分野】
本発明は、天井に設けられた引掛シーリングや引掛埋込ローゼット等の引掛型天井配線器具に照明器具を取り付けるための照明器具取付構造に関する。
【０００２】
【従来の技術】
図１６は、従来一般に用いられている照明器具取付構造を示す斜視図である。図において、天井に設けられている引掛型天井配線器具１０１に照明器具本体部１０３を取り付けるには、まず、円盤状の照明器具取付装置１０２を引掛型天井配線器具１０１に取り付ける。次に、照明器具本体部１０３の嵌合筒部１０４を照明器具取付装置１０２に外挿する。嵌合筒部１０４の内側には図示しないばねで内方に付勢された一対の爪１０５が設けられており、この爪１０５が照明器具取付装置１０２と係合して照明器具本体部１０３は保持される。爪１０５は、照明器具本体部１０３が照明器具取付装置１０２へ円滑に外挿されるように先端部がテーパ加工されている。また、照明器具本体部１０３を照明器具取付装置１０２から外すときには、操作部１０６により爪１０５を強制的に開くことができるように構成されている。
【０００３】
図１７は上記照明器具取付装置１０２を斜め下方から見た斜視図である。照明器具取付装置１０２の上面には引掛型天井配線器具１０１（図１６）に引掛接続するための一対の栓刃１０７が設けられている。また、側面の周方向には溝１０２ａが形成され、ここに略Ｃ字状（図１８参照）のリング１０８が装着されている。リング１０８は取り外しが可能であり、引掛型天井配線器具１０１の種類に合わせて着脱される。
例えば引掛型天井配線器具１０１が図１６に示すような引掛シーリング（完全露出型）である場合は、リング１０８を装着した状態で照明器具本体部１０３を取り付ける。この場合、爪１０５はリング１０８の外周面上を乗り越えて照明器具取付装置１０２の上面に達し、ここに係合する。これにより照明器具本体部１０３が保持される。
一方、引掛型天井配線器具１０１が、天井からの突出長が引掛シーリングより短い引掛埋込ローゼット（半埋込型）である場合は、リング１０８を取り外して溝１０２ａを塞がない状態にする。この場合、嵌合筒部１０４を照明器具取付装置１０２に外挿すると、爪１０５が溝１０２ａに係合する。従って、その位置で照明器具本体部１０３を安定保持することが可能になる。
【０００４】
このようにして、リング１０８の着脱により、高さ方向における、照明器具本体部１０３の取付位置を調節することができるように構成されている。この結果、引掛型天井配線器具１０１の種類に関わらず、照明器具本体部１０３の上部と天井との距離を略一定に保つことができる。この照明器具本体部１０３の上部と天井との間には、照明器具本体部１０３のがたつきを抑えるためのスペーサ（虫よけを兼用したもの）が取り付けられる。
【０００５】
【発明が解決しようとする課題】
しかしながら、上記のような照明器具取付装置１０２と照明器具本体部１０３とによる従来の照明器具取付構造においては、照明器具本体部１０３の爪１０５が照明器具取付装置１０２に確実に係合していないにもかかわらず照明器具本体部１０３が照明器具取付装置１０２に一応保持される場合がある。このような場合には、操作部１０６が定位置に戻らないことにより、操作部１０６のところに赤いマーキングが見えるようになっている。そこで、取付作業者はこの赤いマーキングを見て照明器具本体部１０３が照明器具取付装置１０２に確実に係合していないことを知り、照明器具本体部１０３の取付直しを行って、確実な係合をさせることができる。しかしながら、このような手順は取付作業者の注意力に依存するため確実性に乏しく、取付作業者がマーキングを見落とした場合はそのままの状態で放置され、その結果、照明器具本体部１０３が落下する危険性があった。
【０００６】
一方、上記のような従来の照明器具取付装置１０２では、取付作業者がリング１０８の着脱を間違える場合があった。例えば、引掛型天井配線器具１０１が引掛シーリングであるにもかかわらず、取付作業者が誤ってリング１０８を外してしまった場合には、照明器具本体部１０３の取付はできるものの、その上面と天井との距離が適正値より大きくなる。この結果、特に横引きスイッチ（スイッチひもが水平に張架されてから垂下したもの）を備えた照明器具の場合、スイッチ操作によって照明器具本体部１０３が揺動して不安定になる。逆に、引掛型天井配線器具１０１が引掛埋込ローゼットであるにもかかわらず、リング１０８を外さなかった場合は、照明器具本体部１０３が取り付けられなくなる。
このように、取付作業者がリング１０８の着脱を間違えると、照明器具の適正な取付ができなくなるという問題点があった。
【０００７】
上記のような従来の問題点に鑑み、本発明の第１の目的は、取付作業者の注意力に依存することなく、照明器具の落下を常に確実に防止する照明器具取付構造を提供することにある。
また、本発明の第２の目的は、取付作業者の注意力に依存することなく、常に確実に照明器具本体部の適正な取付を行うことができる照明器具取付構造を提供することにある。
【０００８】
【課題を解決するための手段】
本発明は、天井に設けられた引掛型天井配線器具に引掛接続された照明器具取付装置に照明器具本体部を着脱可能に取り付ける照明器具取付構造であって、前記照明器具本体部は、前記照明器具取付装置との電気的接続を行うためのコネクタを有する筐体部と、前記筐体部により可動に保持され、前記照明器具取付装置と係合する係合部と、前記係合部と一体的に動作する操作部と、前記筐体部により可動に保持され、前記係合部が前記照明器具取付装置と適正に係合したときにのみ、前記操作部と係合してその操作を妨げる位置に移動可能であるとともに、前記操作部と非係合状態では前記コネクタの接続を妨げるインタロック部材とを備えたことを特徴とするものである（請求項１）。
このような照明器具取付構造では、係合部が適正に照明器具取付装置に係合するように照明器具本体部が取り付けられた場合にのみ、インタロック部材が操作部と係合する位置に移動可能となり、インタロック部材を移動することにより、コネクタ接続が可能となる。従って、係合部が適正に照明器具取付装置に係合していない場合は、インタロック部材を移動させることはできず、コネクタ接続ができない。
【０００９】
上記照明器具取付構造（請求項１）において、コネクタに接続された相手側のコネクタが、インタロック部材の移動を妨げるものであってもよい（請求項２）。
この場合、照明器具本体部のコネクタに接続された照明器具取付装置のコネクタがインタロック部材の移動を妨げることにより、インタロック部材は操作部と非係合状態になることができず、操作部の操作を行うことができない。すなわち、コネクタ接続がなされた状態では照明器具本体部を取り外すことができない。
【００１０】
また、本発明は、天井からの突出長が相異なる少なくとも２種類の引掛型天井配線器具に接続される照明器具取付装置に、照明器具本体部を着脱可能に取り付ける照明器具取付構造であって、
前記照明器具取付装置は、引掛型天井配線器具に引掛接続する栓刃を端面に有し、かつ、照明器具本体部側の係合部と選択的に係合して当該照明器具本体部を支持する第１の支持部を有する第１取付部材と、前記第１取付部材と係合するとともに、この第１取付部材に対して、天井面と直交する方向に所定範囲で移動可能であって、一の引掛型天井配線器具とは干渉せず、他の引掛型天井配線器具と干渉する突起部と、前記係合部と選択的に係合して前記照明器具本体部を支持する第２の支持部とを有する第２取付部材と、自由な状態において前記突起部が前記端面より突出した状態に維持すべく、前記第２取付部材を前記第１取付部材に対して相対的に付勢する弾性体とを備え、前記栓刃を前記一の引掛型天井配線器具に引掛接続したとき前記第１の支持部によって前記照明器具本体部を支持し、前記栓刃を前記他の引掛型天井配線器具に引掛接続するとき、前記第２取付部材の前記突起部が当該引掛型天井配線器具に当接した状態から前記第１取付部材を押し上げることにより、前記端面から突出した前記突起部を前記弾性体に抗して引っ込ませ、これにより、前記第２取付部材を前記第１取付部材に対して相対的に移動させ、この移動に基づいて、前記突出長の差を相殺する方向に移動した前記第２の支持部によって前記照明器具本体部を支持するものであり、
前記照明器具本体部は、前記照明器具取付装置との電気的接続を行うためのコネクタを有する筐体部と、前記筐体部により可動に保持され、前記照明器具取付装置と係合する係合部と、前記係合部と一体的に動作する操作部と、前記筐体部により可動に保持され、前記係合部が前記照明器具取付装置と適正に係合したときにのみ、前記操作部と係合してその操作を妨げる位置に移動可能であるとともに、前記操作部と非係合状態では前記コネクタの接続を妨げるインタロック部材とを備えたものであってもよい（請求項３）。
【００１１】
このような照明器具取付構造においては、栓刃を前記一の引掛型天井配線器具に引掛接続したときは第１の支持部が照明器具本体部を支持する。一方、栓刃を前記他の引掛型天井配線器具に引掛接続するときは、第２取付部材の突起部が引掛型天井配線器具に当接した状態から第１取付部材を弾性体に抗して押すことにより、第２取付部材を前記第１取付部材に対して相対的に移動させ、この移動に基づいて、前記突出長の差を相殺する方向に移動した第２の支持部が照明器具本体部を支持する。従って、引掛型天井配線器具の種類による天井面からの突出長の違いを、支持部を変えることにより補償して、照明器具本体部と天井面との距離を略一定に保つことができる。
また、このような照明器具取付構造では、係合部が適正に照明器具取付装置に係合するように照明器具本体部が取り付けられた場合にのみ、インタロック部材が操作部と係合する位置に移動可能となり、インタロック部材を移動することにより、コネクタ接続が可能となる。従って、係合部が適正に照明器具取付装置に係合していない場合は、インタロック部材を移動させることはできず、コネクタ接続ができない。
【００１２】
上記照明器具取付構造（請求項３）において、引掛型天井配線器具に引掛接続する状態において前記第２取付部材は前記第１取付部材より実質的に下方にあり、第２取付部材の側面に、第１取付部材の一部を下方に露出させる切欠部が設けられていてもよい（請求項４）。
この場合、切欠部に指を通して、指先で第１取付部材を押し上げながら、照明器具取付装置を取り付ける操作を行うことができる。
【００１３】
上記照明器具取付構造（請求項４）において、前記弾性体を保持する押さえ板を前記第２取付部材の下方に配置し、この押さえ板にも前記第１取付部材の前記一部を下方に露出させる切欠部が設けられ、この切欠部による切欠エリアが、前記天井面と直交する方向に見たとき、前記第２取付部材の切欠部の切欠エリアと重なっていることが好ましい（請求項５）。
この場合、切欠エリアの重なりによって天井面と直交する方向に連続した凹部空間が形成され、ここに指を入れることができるので、切欠部に指を当てて、指先で第１取付部材を押し上げながら、照明器具取付装置を稔回する操作を行うことができる。
【００１４】
上記照明器具取付構造（請求項３）において、第２の支持部によって照明器具本体部が支持されるとき、第１の支持部と第２の支持部との高さ位置の差は、前記突出長の差に実質的に等しいことが好ましい（請求項６）。
この場合、引掛型天井配線器具の種類による突出長の差が支持部の高さ位置の差により一定確実に相殺される。従って、照明器具本体部と天井面との距離を一定に保つことができる。
【００１５】
【発明の実施の形態】
図１〜図１５は、本発明の一実施形態による照明器具取付構造に関する図面である。まず、図５〜７に基づいて、照明器具取付装置の構造について説明する。図５は照明器具取付装置１０の組立を示す斜視図である。図に示すように、照明器具取付装置１０は、第１取付部材１、第２取付部材２、ばね３、一対のガイド部材４、押さえ板５及びカバー６により構成されている。なお、各図において、本発明に直接関係のない構成部分は図示を省略するか若しくは図示しても説明を省略する。
【００１６】
図６は、上記第１取付部材１を示す図であり、（ａ）は平面図、（ｂ）は側面図、（ｃ）は底面図である。図５及び図６において、第１取付部材１の筐体は樹脂からなり、その基本的形状は、円形の上面部１ａと、円筒面状の側面部１ｂと、側面部１ｂの外周下端部に形成された鍔状部１ｃとを備えたものである。
引掛型天井配線器具に引掛接続される一対の栓刃１１は、上記上面部１ａから上方に突出して設けられている。上面部１ａの周辺部同一円周上の４箇所には、後述の第２取付部材２の突起部２ｄを嵌挿させるため、円弧状に逃がし孔１ｄが設けられている。また、上面部１ａの一対の孔１ｅは、ねじ７（図５）を貫通させるために設けられている。一方、図６の（ｃ）に示すように、上面部１ａの裏側には、栓刃１１とそれぞれ接続された一対のリード線端子１２が設けられている（但し、リード線の図示は省略する。）。
【００１７】
第１取付部材１の側面部１ｂは、外周上の相対向する２箇所の所定範囲が切除され、切欠部１ｆとなっている。切欠部１ｆに沿った側面部１ｂの周方向エッジ部分には突起部１ｇが設けられている。上記鍔状部１ｃは、一対の切欠部１ｆを除く側面部１ｂの外周下端部に設けられ、照明器具本体部を支える「第１の支持部」としての機能を有している（詳細は後述する。）。
【００１８】
次に、図７は、上記第２取付部材２を示す図であり、（ａ）は平面図、（ｂ）は側面図、（ｃ）は底面図である。図５及び図７において、第２取付部材２は樹脂からなり、その基本的形状は、円形の一部としての形状の上面部２ａと、部分的に円筒面状の側面部２ｂと、側面部２ｂの外周下端部に形成された鍔状部２ｃとを備えたものである。
４個の突起部２ｄは、上面部の外周端部から上方へ突設され、前述の第１取付部材１の逃がし孔１ｄに嵌挿されるように同一円周上に配置されている。ばね保持部２ｅは上面部２ａの中央をプレス成形したもので、図の（ａ）及び（ｂ）では凸部であり、（ｃ）では凹部である。ばね保持部２ｅを挟んで一対形成された角孔２ｆは、前述のリード線端子１２の逃がし孔となる。また、ガイド部材４を嵌挿させるため、ばね保持部２ｅを挟んで丸孔２ｇが一対形成されている。上面部２ａの裏側に突設された一対のボス２ｈには、図５におけるねじ８を螺合させるための雌ねじが形成されている。
【００１９】
第２取付部材２の側面部２ｂ及び上面部２ａは、外周上の相対向する２箇所の所定範囲が切除され、切欠部２ｉとなっている。上記鍔状部２ｃは、一対の切欠部２ｉを除く側面部１ｂの外周下端部に設けられ、照明器具本体部を支える「第２の支持部」としての機能を有している（詳細は後述する。）。鍔状部２ｃは、その外周径が下方ほど小さくなるようにテーパ状に加工されている。
【００２０】
図５に示すように、照明器具取付装置１０は、上記のように構成された第１取付部材１及び第２取付部材２に、さらにばね３、樹脂製のガイド部材４、金属製の押さえ板５、金属製のカバー６、ねじ７及びねじ８を用いて組み立てられる。ここで、ばね３は圧縮ばねである。ガイド部材４はスタッド状の外観形状で、内部にはねじ７を挿通させる貫通孔４ａが設けられている。また、ガイド部材４の円筒部（鋲頭部を除く部分）４ｂの直径は前述の第２取付部材２の丸孔２ｇの内径より小さい。押さえ板５の中央部にはプレス成形されたばね保持部５ａが凹部として形成され、そのばね保持部５ａを挟んで両側に雌ねじ部５ｂが形成されている。また、押さえ板５には、第２取付部材２のボス２ｈの逃がし孔５ｃが設けられているとともに、他の円形部分の外周より切り込まれた切欠部５ｄが設けられている。カバー６にはねじ８を挿通させるための一対の孔６ａと、外周上の相反位置に円弧状の切欠部６ｂとが設けられている。
【００２１】
ここで、図の上下方向、すなわち照明器具取付装置１０を取り付ける天井面と直交する方向を装置の「軸方向」とすると、軸方向に直交する平面における押さえ板５の上記切欠部５ｄによる切欠エリアは、第２取付部材２の切欠部２ｉの同平面における切欠エリアと重なるように配置構成されている。すなわち、平面図的に当該装置を見たとき、各切欠部５ｄ及び２ｉの存在によって装置全体の外周から凹む領域部分が少なくともその一部において共通しているのである。同様に、軸方向に直交する平面におけるカバー６の上記切欠部６ｂによる切欠エリアも、第２取付部材２の切欠部２ｉの同平面における切欠エリアと重なるように配置構成されている。従って、カバー６の切欠部６ｂ、押さえ板５の切欠部５ｄ及び第２取付部材２の切欠部２ｉによる、軸方向に直交する平面上の切欠エリアが所定範囲で相互に一致している。また、第２取付部材２の切欠部２ｉの円周上における位置は、第１取付部材１の切欠部１ｆの円周上における位置と略一致している。
【００２２】
照明器具取付装置１０を組み立てるには、まず、第２取付部材２の突起部２ｄが第１取付部材１の逃がし孔１ｄに嵌挿されるように第１取付部材１と第２取付部材とを互いに係合させる。次に、ばね３を第２取付部材２のばね保持部２ｅと押さえ板５のばね保持部５ａとで挟持し、かつ、ガイド部材４の円筒部４ｂが第２取付部材２の丸孔２ｇに挿通されるように、押さえ板５と第２取付部材２とを相互に押しつける。この状態でねじ７を通し、押さえ板５の雌ねじ部５ｂに螺合させる。最後に、カバー６をねじ８により、第２取付部材２に固定する。
【００２３】
このようにして組立完成した照明器具取付装置１０において、第２取付部材２は、第１取付部材１との係合及びガイド部材４による案内によって、軸方向に直交する平面での回転を規制されるとともに、軸方向には、ばね３の付勢に抗して第１取付部材に対して相対的に所定範囲で移動可能となる。
また、前述のようにカバー６の切欠部６ｂ、押さえ板５の切欠部５ｄ及び第２取付部材２の切欠部２ｉの、軸方向に直交する平面上の切欠エリアが共通し、さらに第２取付部材２の切欠部２ｉの円周上における位置は第１取付部材１の切欠部１ｆの円周上における位置と略一致しているため、軸方向に連続した所定の凹部空間が形成される。
【００２４】
図８は、上記のようにして組み立てた照明器具取付装置１０の側面図である。図に示すように凹部Ｖが側面及び側面から内方へ入り込んで形成されている。この凹部Ｖは、照明器具取付装置１０の装着時において人の指を当て得る凹部となる。また、第１取付部材１の上面部１ａには切欠部が設けられていないため、この上面部１ａ裏面の一部が下方に露出した状態（下方から見える状態）となり、そこに指の先端が当たって押圧力が付与される。すなわち、一対の凹部Ｖに親指と例えば人指し指をあてがい、照明器具取付装置１０を摘むように保持しつつ、栓刃１１を引掛型天井配線器具に挿入して稔回することにより、当該照明器具取付装置１０を引掛型天井配線器具に取り付けることができる。このとき、凹部Ｖに指が収まることで稔回力も付与しやすい。
なお、当該組立状態において、第２取付部材２の突起部２ｄが第１取付部材１の上面から突出する高さをｈ１、第１取付部材１の鍔状部１ｃの高さをｈ２とすると、ｈ１＋ｈ２は、後述する引掛シーリングと引掛埋込ローゼットとの天井面から下方への突出長の差に等しくなるように設計されている。
【００２５】
次に、以上のようにして組み立てられた照明器具取付装置１０を、引掛型天井配線器具に取り付ける場合の状態について説明する。
図９は、引掛型天井配線器具が引掛シーリング３１である場合の照明器具取付装置１０の取付状態を示す側面図である。引掛シーリング３１は引掛埋込ローゼットと比較すると、天井３２から下方への突出長（すなわち高さ）Ｈ１が大きく、全幅Ｗ及び全長Ｌは比較的小さい。この全長Ｌ及び全幅Ｗともに第２取付部材２の４個の突起部２ｄによって形成される円の内径より小さい。従って、引掛シーリング３１に照明器具取付装置１０を取り付けても、突起部２ｄはどこにも干渉しない。すなわち、照明器具取付装置１０は図８に示す組立状態のまま取り付けされる。照明器具本体部の係合部（詳細後述）は、第１取付部材１の鍔状部１ｃの上面に乗る形で保持される。この鍔状部１ｃの上面と天井面との距離をＨｃとする。
【００２６】
図１０は、引掛型天井配線器具が引掛埋込ローゼット３３である場合の照明器具取付装置１０の取付状態を示す側面図である。引掛埋込ローゼット３３は円盤状であり、引掛シーリング３１と比較すると、天井３２からの突出長Ｈ２が小さく、直径Ｄは比較的大きい。この直径Ｄは４個の突起部２ｄによって形成される円の外径より大きい。従って、引掛埋込ローゼット３３に照明器具取付装置１０を取り付けようとすると、突起部２ｄが引掛埋込ローゼット３３に必ず当接する。突起部２ｄが引掛埋込ローゼット３３に当接した状態からさらに第１取付部材１を押し上げることにより、ばね３（図５）に抗して第２取付部材２が第１取付部材１に対して相対的に下降する。これにより、第１取付部材１の上面部１ａから突出していた突起部２ｄは引っ込み、第２取付部材２の鍔状部２ｃと第１取付部材の鍔状部１ｃとの間に照明器具本体部の係合部が入り込み得る隙間ができる。このときの天井面から鍔状部２ｃの上面までの距離Ｈｒは、前述のＨｃとの比較において、引掛シーリング３１と引掛埋込ローゼット３３との突出長の差（Ｈ１−Ｈ２）の分が減少要因となるが、鍔状部１ｃと２ｃとの上面の高さの差ｄＨが増加要因となる。この差ｄＨは、前述のｈ１＋ｈ２に等しい。従って、高さの差ｄＨは、引掛シーリング３１と引掛埋込ローゼット３３との天井面からの突出長の差に相当する。すなわち、ｄＨ＝Ｈ１−Ｈ２である。従って、増加要因と減少要因が相殺し、結局、距離Ｈｒ＝Ｈｃとなる。
【００２７】
図１１及び図１２は、引掛型天井配線器具に取り付けられた照明器具取付装置１０に照明器具本体部４０を装着した状態を示す断面図であり、図１１は、引掛型天井配線器具が引掛シーリング３１である場合を、また図１２は引掛型天井配線器具が引掛埋込ローゼット３３である場合を、それぞれ示している。
図１１において、照明器具本体部４０は筐体部４１と、その上部に取り付けられた天板部４２と、先端部がテーパ加工され、筐体部４１からばね４３により内側方向に付勢された係合部４４とを備えている。なお、照明器具は照明器具本体部４０と共に構成されるが、ここでは図示を省略している。
【００２８】
上記照明器具本体部４０を含む照明器具全体の重量は、係合部４４に負荷される。照明器具本体部４０を照明器具取付装置１０に取り付けるには、図９に示した照明器具取付装置１０の取付完了状態から照明器具本体部４０を下方から外挿する。これにより、係合部４４が第２取付部材２の鍔状部２ｃに当接してばね４３に抗して外方へ後退する。こうして照明器具本体部４０の上昇とともに係合部４４は鍔状部２ｃを乗り越え、続いて、第１取付部材１の鍔状部１ｃを乗り越える。ここで係合部５５は鍔状部１ｃの上面と係合する。これにより照明器具本体部４０は照明器具取付装置１０に確実に保持される。天井３２の天井面と天板部４２の外周最上面との間には隙間Ｘｃが形成され、ここには虫よけ兼用のスペーサ４５が取り付けられる。
【００２９】
一方、図１２に示すように引掛型天井配線器具が引掛埋込ローゼット３３である場合においては、照明器具本体部４０の上昇とともに係合部４４は第２取付部材２の鍔状部２ｃを乗り越える。ここで係合部５５は鍔状部２ｃの上面と係合する。これにより照明器具本体部４０は照明器具取付装置１０に確実に保持される。天井３２の天井面と天板部４２の外周最上面との間に形成される隙間Ｘｒは、前述のように、引掛シーリング３１の場合の天井面から鍔状部１ｃ上面までの距離Ｈｃ（図９）と引掛埋込ローゼット３３の場合の天井面から鍔状部２ｃ上面までの距離Ｈｒが実質的に等しいことにより、引掛シーリング３１の場合の隙間Ｘｃと実質的に等しい。すなわち、引掛型天井配線器具が引掛シーリング３１であるか引掛埋込ローゼット３３であるかに関わらず、天板部４２と天井面との隙間は一定である。従って、一定のスペーサ等を設けることにより、常に、照明器具本体部４０を安定して取り付けることができる。
【００３０】
なお、本実施形態においては、照明器具取付装置１０の取り付け対象を、引掛シーリング及び引掛埋込ローゼットとしたが、他の種類の引掛型天井配線器具にも適用できることはいうまでもない。また、鍔状部１ｃ及び２ｃの他にさらに同様な支持部を設ければ、３以上の種類の引掛型天井配線器具に対しても、照明器具を一定の取付状態に取り付けることが可能である。また、ばね４の代わりに他の弾性体を用いることも可能である。
【００３１】
図１３は、照明器具取付装置１０の第２の例における第１取付部材１及び第２取付部材２を示す斜視図である。本例では、第１の例における第１取付部材１の切欠部１ｆ（図５）の位置に、第１取付部材１の外周面より凹んで、かつ、下方に延伸されたガイド部１ｈが形成されている。図の一点鎖線で示すように、第２取付部材２の切欠部２ｉは第１取付部材１のガイド部１ｈを逃がすべく、所定の寸法で形成されている。なお、図示は省略しているが、本例においても、第１の例における押さえ板５及びカバー６と同様の部材を設け、それらにも上記ガイド部１ｈに適合した切欠部を設ける。
このように構成された第２の例の照明器具取付装置１０においては、取付時に、作業者がガイド部１ｈに指の全面を当てて、取付（又は取り外し）操作を行うことができる。従って、非常に操作しやすいという利点がある。また、装置全体を組み立てたときガイド部１ｈの存在によって内部の露出が防止されるので、内部への異物の侵入防止効果がある。
なお、その他の構成及び取付動作は第１の例と同様である。
【００３２】
図１４は、照明器具取付装置１０の第３の例における第１取付部材１の概略外形形状を示す平面図である。本例では、第１の例における切欠部１ｆに相当する外周上の対向位置に、外周より凹んだ互いに平行な平面状の操作部１ｉを設け、上面部１ａのみを円形としたものである。なお、図示は省略しているが、本例においても、第１の例における第２取付部材、押さえ板５及びカバー６と同様の部材を設け、それらを上記第１取付部材１と適合した形状とすることはいうまでもない。
このように構成された第３の例の照明器具取付装置１０においては、取付時に、作業者が操作部１ｉに指の全面を当てて、取付（又は取り外し）操作を行うことができる。しかも、操作部１ｉが比較的広いため、複数の指を当てることもできる。従って、簡素な構成であって、かつ、非常に操作しやすいという利点がある。また、第２の例と同様に、装置全体を組み立てたときの内部の露出が防止されるので、内部への異物の侵入防止効果がある。

図１５は、照明器具取付装置１０の第４の例における第１取付部材を示す斜視図である。本例における第１取付部材１は、鍔状部１ｃの下端部外周側が小区間ごとに面取りされて、複数のテーパ部１ｊが形成されている。隣接するテーパ部１ｊ間には面取りしない非テーパ部１ｋが介在している。その他は、第１の例と同様の構成である。
このように構成された第４の例の照明器具取付装置１０においては、取付時に作業者の指が切欠部１ｆ以外の外周部分に触れても、テーパ部１ｊの存在によって第１取付部材１と第２取付部材２との間に指の肉を挟まれることがほとんどない。従って、取付作業をより安全に行うことができる。
なお、本例のようにテーパ部１ｊを設ける構成は、第２及び第３の例の構成と併用してもよい。

次に、照明器具本体部４０の構造（但し、天板部４２及びスペーサ４５は省略する。）について、図１〜図４を参照して、詳細に説明する。
図１及び図２は、照明器具本体部４０の底面図であり、図３は垂直断面図（上方が天井側）である。図１及び図３において、係合部４４の一部として一体的に形成された操作部４４ａは、筐体部４１に設けられた孔４１ａから下方に突出している。操作部４４ａは孔４１ａに対して遊嵌された状態にあり、この操作部４４ａをばね４３に抗して外方に操作することにより、係合部４４の内方先端部を外方に後退させることができる。係合部４４が照明器具取付装置１０と適正に係合した状態において、一対の操作部４４ａは各孔４１ａの内方側端面に当接しており、この位置が操作部４４ａの定位置である。
コネクタ４７は筐体部４１の底面に設けられており、照明器具（図示せず）の電源線がここに接続されている。また、照明器具取付装置１０のリード線端子１２（図６の（ｃ）参照）に接続されたリード線１３の先端に取り付けられた相手側のコネクタ１４が、コネクタ４７に挿入されることにより、引掛シーリング３１等から照明器具への電源接続が完了する。
【００３５】
インタロック部材４６は筐体部４１に対して所定範囲で回動自在に取り付けられており、図１に示す状態から時計回り方向に回動可能である。図４は、このインタロック部材４６の形状を示す底面図及び側面図である。図４において、インタロック部材４６は、リング状の回動基部４６ａと、この回動基部４６ａの周上の２箇所から外方へ突出形成され、回動基部４６ａと同心円弧の一方向に沿って形成されたＵ字状の凹部４６ｃを有するロック部４６ｂと、一方のロック部４６ｂに隣接して形成されたカバー部４６ｄとを有している。
【００３６】
インタロック部材４６の回動中心Ｏ（図１）から見た凹部４６ｃの径方向位置は、操作部４４ａが定位置にあるときのその径方向位置と合致している。従って、図１に示すように、ロック部４６ｂを操作部４４ａに係合させることができる。この状態では、操作部４４ａを操作することができない。また、コネクタ４７は露出している。
一方、図１に示す位置から時計回り方向にインタロック部材４６を回動させることにより、図２に示すように、ロック部４６ｂが操作部４４ａから外れて、カバー部４６ｄがコネクタ４７を覆う状態となる。この状態では、操作部４４ａを操作することができるが、コネクタ４７に相手側のコネクタ１４を接続することはできない。
【００３７】
照明器具本体部４０を照明器具取付装置１０に取り付けるとき、係合部４４が確実に照明器具取付装置１０に係合していないが一応保持された状態であるとすると、係合部４４と一体の操作部４４ａが定位置に戻らず、例えば図２の点線で示す位置にある。従って、このときインタロック部材４６を回動させようとしても、操作部４４ａの位置と孔４６ｃの位置が合わないため、回動させることができない。従って、コネクタ４７を露出させることができないので、相手側のコネクタ１４を接続することができない。これでは、照明器具の取付作業が終了しない。コネクタ４７に相手側のコネクタ１４を接続するためには、照明器具本体部４０を取付け直して、係合部４４を確実に照明器具取付装置１０に係合させ、操作部４４ａを定位置にすることが必要となる。すなわち、必然的に確実な係合を行わせることになる。
【００３８】
一方、照明器具本体部４０を照明器具取付装置１０から取り外すには、図１に示す状態からでは操作部４４ａを操作することができない。そこで、インタロック部材４６を時計回り方向に回動させようとすると、コネクタ４７に接続されている相手側のコネクタ１４が邪魔になって回動させることができない。従って、まず、相手側のコネクタ１４を外し、その後、インタロック部材４６を回動させることが必要となる。すなわち、コネクタ４７から相手側のコネクタ１４を外すことなく、照明器具本体部４０を照明器具取付装置１０から取り外すことはできない。このようなインタロック構造によれば、相手側のコネクタ１４を接続したまま照明器具本体部４０を取り外そうとして双方のコネクタ４７及び１４やリード線１３を傷めるという事態も起こり得ない。
【００３９】

請求項５の照明器具取付構造によれば、切欠エリアの重なりによって天井面と直交する方向に連続した凹部空間が形成され、ここに指を入れることができるので、切欠部に指を当てて、指先で第１取付部材を押し上げながら、照明器具取付装置を稔回する操作を行うことができ、照明器具取付装置を引掛型天井配線器具に容易に取り付けることができる。
【００４４】
請求項６の照明器具取付構造によれば、引掛型天井配線器具の種類による突出長の差が支持部の高さ位置の差により一定確実に相殺されるので、照明器具本体部と天井面との距離を一定に保つことができる。従って、一定のスペーサを照明器具本体部と天井面との間に設けることで照明器具本体部のがたつきを確実に抑えるとともに虫の侵入も確実に防止することができる。

BACKGROUND OF THE INVENTION
The present invention relates to a lighting fixture mounting structure for mounting a lighting fixture on a hook-type ceiling wiring fixture such as a hook ceiling or a hook embedded rosette provided on a ceiling.
[0002]
[Prior art]
FIG. 16 is a perspective view showing a lighting fixture mounting structure generally used conventionally. In the figure, in order to attach the lighting fixture main body 103 to the hook-type ceiling wiring fixture 101 provided on the ceiling, first, the disk-shaped lighting fixture mounting device 102 is attached to the hook-type ceiling wiring fixture 101. Next, the fitting tube portion 104 of the luminaire main body portion 103 is extrapolated to the luminaire attachment device 102. A pair of claws 105 urged inward by a spring (not shown) is provided inside the fitting cylinder portion 104, and the claws 105 engage with the luminaire mounting device 102 so that the luminaire main body portion 103 is Retained. The nail | claw 105 has the front-end | tip part taper-processed so that the lighting fixture main-body part 103 may be smoothly extrapolated to the lighting fixture attachment apparatus 102. FIG. Further, when the luminaire main body 103 is detached from the luminaire attachment device 102, the nail 105 can be forcibly opened by the operation portion 106.
[0003]
FIG. 17 is a perspective view of the luminaire mounting device 102 as viewed obliquely from below. On the upper surface of the lighting fixture mounting apparatus 102, a pair of plug blades 107 for hooking and connecting to the hook-type ceiling wiring fixture 101 (FIG. 16) is provided. In addition, a groove 102a is formed in the circumferential direction of the side surface, and a substantially C-shaped ring 108 (see FIG. 18) is attached thereto. The ring 108 can be removed, and is attached / detached according to the type of the hook-type ceiling wiring device 101.
For example, when the hook-type ceiling wiring device 101 is a hook ceiling (fully exposed type) as shown in FIG. 16, the lighting fixture main body 103 is attached with the ring 108 attached. In this case, the claw 105 climbs over the outer peripheral surface of the ring 108 and reaches the upper surface of the lighting fixture mounting apparatus 102 and engages there. Thereby, the lighting fixture main body 103 is held.
On the other hand, when the hook-type ceiling wiring device 101 is a hook embedded rosette (semi-embedded type) whose protrusion length from the ceiling is shorter than the hook ceiling, the ring 108 is removed so that the groove 102a is not blocked. In this case, when the fitting tube portion 104 is extrapolated to the lighting fixture mounting device 102, the claw 105 is engaged with the groove 102a. Therefore, the lighting fixture main body 103 can be stably held at that position.
[0004]
Thus, the attachment position of the lighting fixture main body 103 in the height direction can be adjusted by attaching and detaching the ring 108. As a result, the distance between the upper part of the lighting fixture main body 103 and the ceiling can be kept substantially constant regardless of the type of the hook-type ceiling wiring fixture 101. Between the upper part of the luminaire main body 103 and the ceiling, a spacer (which also serves as an insect repellent) for suppressing the shakiness of the luminaire main body 103 is attached.
[0005]
[Problems to be solved by the invention]
However, in the conventional lighting fixture mounting structure using the lighting fixture mounting apparatus 102 and the lighting fixture main body 103 as described above, the claw 105 of the lighting fixture main body 103 is not securely engaged with the lighting fixture mounting apparatus 102. Nevertheless, the luminaire main body 103 may be temporarily held by the luminaire attachment device 102. In such a case, since the operation unit 106 does not return to the home position, a red marking can be seen at the operation unit 106. Therefore, the installation operator sees this red marking and knows that the luminaire main body 103 is not securely engaged with the luminaire attachment device 102, and then reattaches the luminaire main body 103 to ensure reliable engagement. Can be combined. However, since such a procedure depends on the attention of the installation worker, the reliability is poor. If the installation operator overlooks the marking, the procedure is left as it is, and as a result, the luminaire main body 103 falls. There was a danger.
[0006]
On the other hand, in the conventional lighting fixture mounting apparatus 102 as described above, there are cases where the mounting operator makes a mistake in attaching and detaching the ring 108. For example, if the installation operator accidentally removes the ring 108 even though the hook-type ceiling wiring apparatus 101 is a hook ceiling, the lighting apparatus main body 103 can be mounted, but the upper surface and the ceiling The distance between and becomes larger than the appropriate value. As a result, in particular, in the case of a luminaire provided with a horizontal pull switch (a switch string that is hung down after being stretched horizontally), the luminaire main body 103 swings and becomes unstable by the switch operation. On the other hand, if the ring 108 is not removed even though the hook-type ceiling wiring device 101 is a hook embedded rosette, the luminaire main body 103 cannot be attached.
As described above, when the attaching operator makes a mistake in attaching and detaching the ring 108, there is a problem that the lighting fixture cannot be properly attached.
[0007]
In view of the conventional problems as described above, a first object of the present invention is to provide a lighting fixture mounting structure that reliably prevents the lighting fixture from falling without depending on the attention of the mounting operator. It is in.
In addition, a second object of the present invention is to provide a lighting fixture mounting structure that can always reliably attach a lighting fixture main body appropriately without depending on the attention of the mounting operator.
[0008]
[Means for Solving the Problems]
The present invention is a lighting fixture mounting structure in which a lighting fixture main body is detachably attached to a lighting fixture mounting device hooked and connected to a hook-type ceiling wiring fixture provided on a ceiling, wherein the lighting fixture main body includes the lighting A housing portion having a connector for electrical connection with the fixture mounting device; an engagement portion that is movably held by the casing portion and engages with the lighting fixture mounting device; and an integral with the engagement portion Only when the engaging portion is properly engaged with the lighting fixture mounting device, and engages with the operating portion to prevent the operation. An interlock member that is movable to a position and prevents connection of the connector in a non-engaged state with the operation portion is provided (claim 1).
In such a lighting fixture mounting structure, the interlock member moves to a position where it engages with the operating portion only when the lighting fixture main body is mounted so that the engaging portion properly engages with the lighting fixture mounting device. The connector can be connected by moving the interlock member. Therefore, when the engaging portion is not properly engaged with the lighting fixture mounting apparatus, the interlock member cannot be moved and the connector cannot be connected.
[0009]
In the lighting fixture mounting structure (Claim 1), the mating connector connected to the connector may prevent the interlock member from moving (Claim 2).
In this case, the connector of the luminaire mounting device connected to the connector of the luminaire main body section prevents the interlock member from moving, so that the interlock member cannot be disengaged from the operation section. Cannot perform the operation. That is, the luminaire main body cannot be removed when the connector is connected.
[0010]
Further, the present invention is a lighting fixture mounting structure for detachably attaching a lighting fixture main body to a lighting fixture mounting apparatus connected to at least two types of hook-type ceiling wiring fixtures having different projecting lengths from the ceiling,
The lighting fixture mounting device has a plug blade hooked to a hook-type ceiling wiring fixture on the end surface, and selectively engages with an engaging portion on the lighting fixture main body side to support the lighting fixture main body. A first mounting member having a first support portion that engages with the first mounting member, and is movable within a predetermined range in a direction perpendicular to the ceiling surface with respect to the first mounting member; A projection part that does not interfere with one hook-type ceiling wiring apparatus and interferes with another hook-type ceiling wiring apparatus, and a second part that selectively engages with the engaging part to support the lighting apparatus main body part. A second mounting member having a support portion, and the second mounting member is biased relative to the first mounting member so as to maintain the protruding portion protruding from the end surface in a free state. When the plug blade is hook-connected to the one hook-type ceiling wiring device When the lighting fixture main body is supported by the first support portion and the plug blade is hook-connected to the other hook-type ceiling wiring fixture, the protrusion of the second mounting member is connected to the hook-type ceiling wiring fixture. The first mounting member from the state of contacting By pushing up, the protrusion protruding from the end face Against the elastic body Let this in By moving the second mounting member relative to the first mounting member, and based on this movement, the lighting device is moved by the second support portion moved in a direction to offset the difference in the protruding length. It supports the main body,
The luminaire main body includes a housing having a connector for electrical connection with the luminaire mounting device, and an engagement that is movably held by the housing and engages with the luminaire mounting device. Only when the engagement portion is properly engaged with the lighting fixture mounting device, and is movably held by the housing portion. And an interlocking member that prevents connection of the connector when disengaged from the operation portion. .
[0011]
In such a lighting fixture mounting structure, when the plug blade is hooked and connected to the one hook-type ceiling wiring fixture, the first support portion supports the lighting fixture body. On the other hand, when the plug blade is hook-connected to the other hook-type ceiling wiring device, the first mounting member is opposed to the elastic body from the state in which the protrusion of the second mounting member is in contact with the hook-type ceiling wiring device. By pushing, the second mounting member is moved relative to the first mounting member, and based on this movement, the second support portion moved in a direction to cancel out the difference in the protruding length is the luminaire main body. Support the part. Therefore, the difference in the protruding length from the ceiling surface depending on the type of the hook-type ceiling wiring device can be compensated by changing the support portion, and the distance between the lighting fixture main body portion and the ceiling surface can be kept substantially constant.
Further, in such a lighting fixture mounting structure, the position where the interlock member engages with the operating portion only when the lighting fixture main body is mounted so that the engaging portion properly engages with the lighting fixture mounting device. The connector can be connected by moving the interlock member. Therefore, when the engaging portion is not properly engaged with the lighting fixture mounting apparatus, the interlock member cannot be moved and the connector cannot be connected.
[0012]
In the lighting fixture mounting structure (Claim 3), the second mounting member is substantially below the first mounting member in a state of being hooked to the hook-type ceiling wiring fixture, and on the side surface of the second mounting member, A notch that exposes a part of the first attachment member downward may be provided (claim 4).
In this case, it is possible to perform an operation of attaching the lighting fixture attachment device while passing the finger through the notch and pushing up the first attachment member with the fingertip.
[0013]
In the lighting fixture mounting structure (claim 4), Elastic body A pressing plate for holding the first mounting member is disposed below the second mounting member, and the pressing plate is also provided with a notch for exposing the part of the first mounting member downward. The cutout area formed by the cutout portion preferably overlaps the cutout area of the cutout portion of the second mounting member when viewed in a direction perpendicular to the ceiling surface. (Claim 5).
in this case, A concave space that is continuous in the direction perpendicular to the ceiling surface is formed by the overlap of the notch areas, and you can put your fingers here, It is possible to perform an operation of winding the lighting fixture attachment device while placing a finger on the notch and pushing up the first attachment member with the fingertip.
[0014]
In the lighting fixture mounting structure (Claim 3), when the lighting fixture main body is supported by the second support portion, the difference in height position between the first support portion and the second support portion is the protrusion. Preferably, it is substantially equal to the difference in length (claim 6).
In this case, the difference in the protrusion length depending on the type of the hook-type ceiling wiring apparatus is surely offset by the difference in the height position of the support portion. Therefore, the distance between the luminaire main body and the ceiling surface can be kept constant.
[0015]

Further, the position on the circumference of the notch 2 i of the second mounting member 2 is substantially the same as the position on the circumference of the notch 1 f of the first mounting member 1.
[0022]
In order to assemble the lighting fixture mounting apparatus 10, first, the first mounting member 1 and the second mounting member are mutually connected such that the protrusion 2 d of the second mounting member 2 is fitted into the relief hole 1 d of the first mounting member 1. Engage. Next, the spring 3 is sandwiched between the spring holding portion 2e of the second mounting member 2 and the spring holding portion 5a of the holding plate 5, and the cylindrical portion 4b of the guide member 4 is formed in the round hole 2g of the second mounting member 2. The presser plate 5 and the second attachment member 2 are pressed against each other so as to be inserted. In this state, the screw 7 is passed and screwed into the female screw portion 5b of the pressing plate 5. Finally, the cover 6 is fixed to the second mounting member 2 with screws 8.
[0023]
In the lighting fixture mounting apparatus 10 thus assembled and completed, the second mounting member 2 is restricted from rotating on a plane orthogonal to the axial direction by engagement with the first mounting member 1 and guidance by the guide member 4. At the same time, it can move in a predetermined range relative to the first mounting member against the bias of the spring 3 in the axial direction.
Further, as described above, the notch portion 6b of the cover 6, the notch portion 5d of the pressing plate 5 and the notch portion 2i of the second mounting member 2 have the same notch area on the plane orthogonal to the axial direction, and the second attachment. Since the position on the circumference of the notch 2 i of the member 2 substantially coincides with the position on the circumference of the notch 1 f of the first mounting member 1, a predetermined recessed space that is continuous in the axial direction is formed.
[0024]
FIG. 8 is a side view of the lighting fixture mounting apparatus 10 assembled as described above. As shown in the figure, a concave portion V is formed so as to enter inward from the side surface and the side surface. The recess V is a recess that can be touched by a human finger when the lighting fixture mounting apparatus 10 is mounted. In addition, since the upper surface portion 1a of the first mounting member 1 is not provided with a notch, a part of the back surface of the upper surface portion 1a is exposed downward (a state seen from below), and the tip of the finger is there. A pressing force is applied. That is, by attaching a thumb and, for example, a forefinger to the pair of recesses V and holding the lighting fixture mounting apparatus 10 so as to hold it, the plug blade 11 is inserted into the hook-type ceiling wiring fixture and wound, whereby the lighting fixture mounting apparatus 10 can be attached to a hook-type ceiling wiring apparatus. At this time, it is easy to apply a winding force because the finger fits in the recess V.
In the assembled state, if the height at which the protrusion 2d of the second mounting member 2 protrudes from the upper surface of the first mounting member 1 is h1, and the height of the hook-shaped portion 1c of the first mounting member 1 is h2, h1 + h2 is designed to be equal to the difference in the downward projecting length from the ceiling surface of the hook ceiling and hook embedded rosette, which will be described later.
[0025]
Next, the state in the case of attaching the lighting fixture mounting apparatus 10 assembled as described above to a hook-type ceiling wiring fixture will be described.
FIG. 9 is a side view showing a mounting state of the lighting fixture mounting apparatus 10 when the hook-type ceiling wiring fixture is the hook ceiling 31. Compared with the hook embedded rosette, the hook ceiling 31 has a longer protruding length (ie, height) H1 from the ceiling 32, and the total width W and the total length L are relatively small. Both the full length L and the full width W are smaller than the inner diameter of the circle formed by the four protrusions 2d of the second mounting member 2. Therefore, even if the lighting fixture mounting apparatus 10 is attached to the hook ceiling 31, the protrusion 2d does not interfere anywhere. That is, the lighting fixture mounting apparatus 10 is mounted in the assembled state shown in FIG. The engaging part (details will be described later) of the luminaire main body is held so as to ride on the upper surface of the bowl-shaped part 1c of the first mounting member 1. The distance between the upper surface of the bowl-shaped portion 1c and the ceiling surface is Hc.
[0026]
FIG. 10 is a side view showing a mounting state of the lighting fixture mounting apparatus 10 when the hook-type ceiling wiring fixture is the hooking embedded rosette 33. The hook-embedded rosette 33 is disk-shaped, and compared with the hook ceiling 31, the protrusion length H2 from the ceiling 32 is small, and the diameter D is relatively large. This diameter D is larger than the outer diameter of the circle formed by the four protrusions 2d. Therefore, when the lighting fixture mounting apparatus 10 is to be attached to the hooked embedded rosette 33, the protrusion 2 d always comes into contact with the hooked embedded rosette 33. By further pushing up the first mounting member 1 from the state in which the projection 2d is in contact with the hooked embedded rosette 33, the second mounting member 2 against the first mounting member 1 against the spring 3 (FIG. 5). Relatively descends. As a result, the protrusion 2d protruding from the upper surface portion 1a of the first mounting member 1 is retracted, and the luminaire main body is located between the hook-shaped portion 2c of the second mounting member 2 and the hook-shaped portion 1c of the first mounting member. A gap is formed in which the engaging portion can enter. At this time, the distance Hr from the ceiling surface to the upper surface of the bowl-shaped portion 2c is reduced by the difference of the protrusion length (H1-H2) between the hook ceiling 31 and the hook embedded rosette 33 in comparison with the above-mentioned Hc. As a factor, the difference dH between the heights of the upper surfaces of the flanges 1c and 2c becomes an increase factor. This difference dH is equal to the aforementioned h1 + h2. Therefore, the height difference dH corresponds to a difference in protrusion length from the ceiling surface of the hook ceiling 31 and the hook embedded rosette 33. That is, dH = H1-H2. Therefore, the increase factor and the decrease factor cancel each other, and the distance Hr = Hc is obtained.
[0027]
11 and 12 are cross-sectional views showing a state in which the luminaire main body 40 is mounted on the luminaire attachment device 10 attached to the hook-type ceiling wiring apparatus, and FIG. 11 shows the hook-type ceiling wiring apparatus being hooked and sealed. FIG. 12 shows a case where the hook type ceiling wiring apparatus is a hook embedded rosette 33. FIG.
In FIG. 11, the luminaire main body 40 has a housing portion 41, a top plate portion 42 attached to the upper portion thereof, and a tip portion that is tapered, and is biased inward by a spring 43 from the housing portion 41. And an engaging portion 44. In addition, although a lighting fixture is comprised with the lighting fixture main-body part 40, illustration is abbreviate | omitted here.
[0028]
The weight of the entire luminaire including the luminaire main body 40 is applied to the engaging portion 44. In order to attach the luminaire main body 40 to the luminaire attachment device 10, the luminaire main body 40 is extrapolated from below from the attachment completion state of the luminaire attachment device 10 shown in FIG. 9. As a result, the engaging portion 44 abuts against the flange-shaped portion 2 c of the second mounting member 2, and retreats outward against the spring 43. Thus, as the luminaire main body 40 is raised, the engaging portion 44 gets over the hook-like portion 2c, and then gets over the hook-like portion 1c of the first mounting member 1. Here, the engaging portion 55 engages with the upper surface of the bowl-shaped portion 1c. Thereby, the luminaire main body 40 is securely held by the luminaire attachment device 10. A gap Xc is formed between the ceiling surface of the ceiling 32 and the outermost uppermost surface of the top plate portion 42, and a insect repellent spacer 45 is attached here.
[0029]
On the other hand, as shown in FIG. 12, when the hook-type ceiling wiring device is the hook embedded rosette 33, the engaging portion 44 gets over the hook-like portion 2 c of the second mounting member 2 as the lighting fixture main body portion 40 rises. . Here, the engaging portion 55 engages with the upper surface of the bowl-shaped portion 2c. Thereby, the luminaire main body 40 is securely held by the luminaire attachment device 10. As described above, the gap Xr formed between the ceiling surface of the ceiling 32 and the outermost uppermost surface of the top plate portion 42 is the distance Hc from the ceiling surface to the upper surface of the bowl-shaped portion 1c in the case of the hooking ceiling 31 (see FIG. The distance Hr from the ceiling surface in the case of 9) and the hook embedded rosette 33 to the upper surface of the bowl-shaped portion 2c is substantially equal, so that the gap Xc in the case of the hook ceiling 31 is substantially equal. In other words, regardless of whether the hook-type ceiling wiring apparatus is the hook ceiling 31 or the hook embedded rosette 33, the gap between the top plate portion 42 and the ceiling surface is constant. Therefore, by providing a certain spacer or the like, the luminaire main body 40 can always be attached stably.
[0030]
In addition, in this embodiment, although the attachment object of the lighting fixture attachment apparatus 10 was set as the hook ceiling and the hook embedded rosette, it cannot be overemphasized that it can apply also to another kind of hook type ceiling wiring fixture. Further, if a similar support portion is provided in addition to the bowl-shaped portions 1c and 2c, it is possible to attach the lighting fixture to a fixed mounting state even with respect to three or more types of hook-type ceiling wiring fixtures. . It is also possible to use another elastic body instead of the spring 4.
[0031]
FIG. 13 is a perspective view showing the first mounting member 1 and the second mounting member 2 in the second example of the lighting fixture mounting apparatus 10. In this example, a guide portion 1h that is recessed from the outer peripheral surface of the first mounting member 1 and extended downward is formed at the position of the notch portion 1f (FIG. 5) of the first mounting member 1 in the first example. Has been. As shown by the one-dot chain line in the figure, the notch 2 i of the second mounting member 2 is formed with a predetermined size so as to allow the guide 1 h of the first mounting member 1 to escape. In addition, although illustration is abbreviate | omitted, also in this example, the member similar to the press board 5 and the cover 6 in a 1st example is provided, and the notch part suitable for the said guide part 1h is also provided in them.
In the lighting apparatus mounting apparatus 10 of the second example configured as described above, at the time of mounting, the operator can perform mounting (or detaching) operation by placing the entire surface of the finger on the guide portion 1h. Therefore, there is an advantage that it is very easy to operate. Further, when the entire apparatus is assembled, the internal exposure is prevented by the presence of the guide portion 1h, so that there is an effect of preventing foreign matter from entering the inside.
Other configurations and mounting operations are the same as those in the first example.
[0032]
FIG. 14 is a plan view showing a schematic outer shape of the first mounting member 1 in the third example of the lighting fixture mounting apparatus 10. In the present example, planar operation parts 1i that are parallel to each other and are recessed from the outer periphery are provided at opposing positions on the outer periphery corresponding to the notch part 1f in the first example, and only the upper surface part 1a is circular. In addition, although illustration is abbreviate | omitted, also in this example, the same member as the 2nd attachment member in the 1st example, the pressing board 5, and the cover 6 is provided, and these are the shapes which adapted the said 1st attachment member 1. Needless to say.
In the luminaire mounting apparatus 10 of the third example configured as described above, at the time of mounting, an operator can perform mounting (or detaching) operation by placing the entire surface of the finger on the operation unit 1i. Moreover, since the operation unit 1i is relatively wide, a plurality of fingers can be applied. Therefore, there is an advantage that it has a simple configuration and is very easy to operate. Further, similarly to the second example, since the internal exposure when the entire apparatus is assembled is prevented, there is an effect of preventing foreign matter from entering the inside.
[0033]
FIG. 15 is a perspective view showing a first mounting member in the fourth example of the lighting fixture mounting apparatus 10. In the first mounting member 1 in this example, the outer peripheral side of the lower end portion of the bowl-shaped portion 1c is chamfered for each small section, and a plurality of tapered portions 1j are formed. A non-chamfered non-tapered portion 1k is interposed between the adjacent tapered portions 1j. Other configurations are the same as those in the first example.
In the lighting fixture mounting apparatus 10 of the fourth example configured as described above, even if the operator's finger touches the outer peripheral portion other than the notch portion 1f during mounting, the presence of the tapered portion 1j causes the first mounting member 1 and Finger flesh is hardly sandwiched between the second mounting member 2. Therefore, the mounting operation can be performed more safely.
The configuration in which the tapered portion 1j is provided as in this example may be used in combination with the configurations in the second and third examples.
[0034]
Next, the structure of the luminaire main body 40 (however, the top plate 42 and the spacer 45 are omitted) will be described in detail with reference to FIGS.
1 and 2 are bottom views of the luminaire main body 40, and FIG. 3 is a vertical sectional view (above the ceiling side). In FIG. 1 and FIG. 3, the operation part 44 a integrally formed as a part of the engagement part 44 projects downward from a hole 41 a provided in the housing part 41. The operation portion 44a is loosely fitted into the hole 41a. By operating the operation portion 44a outward against the spring 43, the inner end of the engagement portion 44 is retracted outward. Can be made. In a state where the engaging portion 44 is properly engaged with the lighting fixture mounting apparatus 10, the pair of operation portions 44a are in contact with the inner side end surfaces of the holes 41a, and this position is a fixed position of the operation portion 44a. .
The connector 47 is provided on the bottom surface of the housing portion 41, and a power line of a lighting fixture (not shown) is connected here. Further, by inserting the mating connector 14 attached to the tip of the lead wire 13 connected to the lead wire terminal 12 (see FIG. 6C) of the lighting fixture mounting device 10 into the connector 47, The power connection from the hook ceiling 31 or the like to the lighting fixture is completed.
[0035]
The interlock member 46 is rotatably attached to the casing 41 within a predetermined range, and can be turned clockwise from the state shown in FIG. FIG. 4 is a bottom view and a side view showing the shape of the interlock member 46. In FIG. 4, the interlock member 46 is formed to project outward from two places on the circumference of the ring-shaped rotation base 46a and the rotation base 46a, and along one direction concentric with the rotation base 46a. A lock portion 46b having a U-shaped recess 46c formed in the above manner, and a cover portion 46d formed adjacent to one lock portion 46b.
[0036]
The radial position of the recess 46c viewed from the rotation center O (FIG. 1) of the interlock member 46 coincides with the radial position when the operation portion 44a is at a fixed position. Therefore, as shown in FIG. 1, the lock portion 46b can be engaged with the operation portion 44a. In this state, the operation unit 44a cannot be operated. The connector 47 is exposed.
On the other hand, when the interlock member 46 is rotated in the clockwise direction from the position shown in FIG. 1, the lock portion 46b is detached from the operation portion 44a and the cover portion 46d covers the connector 47 as shown in FIG. It becomes. In this state, the operation unit 44 a can be operated, but the mating connector 14 cannot be connected to the connector 47.
[0037]
When attaching the luminaire main body 40 to the luminaire attachment device 10, assuming that the engagement portion 44 is not securely engaged with the luminaire attachment device 10 but is temporarily held, the engagement portion 44 is integrated. The operation unit 44a does not return to the home position but is at a position indicated by a dotted line in FIG. 2, for example. Therefore, even if it tries to rotate the interlock member 46 at this time, since the position of the operation part 44a and the position of the hole 46c do not match, it cannot be rotated. Therefore, since the connector 47 cannot be exposed, the mating connector 14 cannot be connected. This does not end the installation work of the lighting fixture. In order to connect the mating connector 14 to the connector 47, the luminaire main body 40 is reattached, the engagement portion 44 is securely engaged with the luminaire attachment device 10, and the operation portion 44a is brought into a fixed position. It will be necessary. In other words, inevitably reliable engagement is performed.
[0038]
On the other hand, in order to remove the luminaire main body 40 from the luminaire attachment device 10, the operation portion 44a cannot be operated from the state shown in FIG. Therefore, if the interlock member 46 is to be rotated in the clockwise direction, the mating connector 14 connected to the connector 47 cannot be rotated because it becomes an obstacle. Therefore, it is necessary to first remove the mating connector 14 and then rotate the interlock member 46. That is, the luminaire main body 40 cannot be removed from the luminaire attachment device 10 without removing the mating connector 14 from the connector 47. According to such an interlock structure, there is no possibility that both the connectors 47 and 14 and the lead wire 13 are damaged by trying to remove the luminaire main body 40 while the counterpart connector 14 is connected.
[0039]

The The lighting fixture mounting device can be easily attached to the hook-type ceiling wiring fixture.
[0044]
According to the lighting fixture mounting structure of claim 6, since the difference in the protrusion length due to the type of the hook-type ceiling wiring fixture is surely offset by the difference in the height position of the support portion, The distance can be kept constant. Therefore, by providing a certain spacer between the luminaire main body and the ceiling surface, it is possible to reliably suppress rattling of the luminaire main body and to prevent insects from entering.
