Description

【０００１】
【発明の属する技術分野】
本発明は例えば天井に設けた埋込穴に照明装置を挿入するだけで容易に照明装置の取り付けを可能にした照明装置に関するものである。
【０００２】
【従来の技術】
図３１は従来の照明装置の構成を示す分解斜視図である。
図において、１は函状の角型の照明装置本体、２は照明装置本体１の天面１ａに設けられたボルト取付穴、３は照明装置本体１の天面１ａに設けられ、化粧板４を係止する係止片、５は天井内の建築構造体より吊り下げられたボルト、６はボルト３に螺合するナット、７は照明装置本体１内に配設されるランプ、８は遮光ルーバー、９は遮光ルーバー８を保持固定するルーバー枠、１０はルーバー枠９に取り付けられたＶ字状の取付ばね、１１は照明装置本体１の側面内側に設けられ、取付ばね１０の先端を係留する係留片である。
【０００３】
従来の照明装置は上記のように構成され、例えば天井面に照明装置を取り付ける場合、まず天井内の建築構造体より吊り下げられたボルト５を照明装置本体１の天面１ａのボルト取付穴２に通し、当該ボルト５にナット６を締め付けて天井面に照明装置本体１の天面１ａを密着させ、天井に照明装置本体１を固定する。次に、天井に取り付けられた照明装置本体１内に露出するボルト５やナット６を隠すため、天面１ａに設けられた係止片３に化粧板４を係止させ、しかる後に照明装置本体１内ランプ７を配設する。
最後に、遮光ルーバー８を保持固定しているルーバー枠９に取り付けられたＶ字状の取付ばね１０を照明装置本体１の側面内側に設けられた係留片１１に引っかけ、照明装置本体１にルーバー枠９を固定して天井面に照明装置を取り付けていた。
【０００４】
【発明が解決しようとする課題】
上記のような従来の照明装置では、天井面に照明装置を取り付ける場合、建築構造体から吊り下げられたボルト５にナット６を締め付けて照明装置本体１の天面１ａを固定するため、事前に照明装置本体１に取り付けられるランプ７や遮光ルーバー８を保持固定したルーバー枠９等を取り外しておかなくてならず事前準備が必要で、しかも照明装置本体１の天面１ａへの固定後にはランプ７やルーバー枠９等を照明装置本体１に取り付けなければならず、極めて作業が面倒であるという問題があった。
【０００５】
また、天井面への照明照明装置本体１の取り付けや、照明照明装置本体１へのランプ７やルーバー枠９等の取り外し、取り付けを行うために、照明装置本体１の天面１ａにボルト取付穴２を設けたり、ボルト５、ナット６を隠すための化粧板４が必要だったり、化粧板４を取り付ける係止片３を設けたり、遮光ルーバー８を固定するためにルーバー枠９や取付ばね１０が必要となるなどにより、部品点数が多くなり、それだけ取り付け、取り外し作業が複雑となり、作業者の作業ミスによっては部品落下の危険もあるという問題点もあった。
【０００６】
本発明は、このような問題点を解決するためになされたものであり、天井への照明器具本体の取り付けが建築構造体から吊り下げられたボルト等による取り付けに依存することのない構造とし、ランプ、遮光ルーバー等の後取り付け作業を不要とする照明装置を得ることを目的とする。
【０００７】

【００１４】
【発明の実施の形態】
実施の形態１．
図１は本発明の実施の形態１に係る照明装置の構成を示す一部切り欠きの分解斜視図、図２は同照明装置の構成を斜視図、図３は同照明装置に取り付けられた取付金具を示す斜視図、図４は同照明装置に取り付けられた取付金具の部品を示す斜視図、図５は同照明装置に取り付けられた取付金具の部品を示す側面図、図６は同照明装置が取付金具により天井面に取り付けられた状態を示す斜視図、図７は同照明装置の遮光ルーバーの照明装置本体への固定直前の状態を示す斜視図、図８は同照明装置の遮光ルーバーの照明装置本体への固定状態を示す斜視図である。
【００１５】
図において、１は函状の角型の照明装置本体、１ａは照明装置本体１の天面、１ｂは照明装置本体１の下端部下方に設けられた外向フランジ、１ｃは照明装置本体１の両端部の側面の中央にそれぞれ形成された角形の開口部、１ｄは天面１ｂの光制御のための折り曲げ部である。
７は照明装置本体１内に折曲部１ｄを挟んで配設されたランプ、１２は遮光ルーバーで、１つのＶ型反射板１３と３本のフラット板１４とを格子状に組み合わせて形成されている。１３ａはＶ型反射板１３の端部の両縁が内側にそれぞれ折り返して形成された折り返し片、１５は照明装置本体１の開口部１ｃに先端が挿入され、当該先端で折り返し片１３ａを支持する断面コ字状の楔固定金具である。
【００１６】
Ｖ型反射板１３の端部を照明装置本体１の側面に固定する固定部材は照明装置本体１の開口部１ｃと、Ｖ型反射板１３の折り返し片１３ａと、開口部１ｃに先端が挿入され、当該先端で折り返し片１３ａを支持する楔固定金具１５とで構成されている。
２３は照明装置本体１を天井板３０に取り付けるための取付金具であり、照明装置本体１の両側部の側面にそれぞれ対称位置に２個取り付けられている。
取付装置２３は一端が照明器具本体１の外向フランジ１ｂに固定されたアーム２４、交差部がアーム２４の下端部に取り付けられたＶ型バネ２５、アーム２４とＶ型バネ２５に係合してアーム２４に沿って上下方向移動可能に取り付けられた押え金具２６および押え金具２６に係合して押え金具２６を下方へ引き落す引き落し金具２７から構成されている。
【００１７】
アーム２４は矩形状に形成され、その縁部２４ａが内側（アーム２４を照明器具本体１に取り付けたときにおける照明器具本体１側）に折り曲げられ断面コ字状に形成されている。アーム２４の両側の縁部２４ａにはスリット２４ｂが設けられている。なお、このアーム２４は外向フランジ１ｂに対してほぼ直角に立設されている。
【００１８】
次に、押え金具２６の形状について説明する。
押え金具２６は矩形状の押え片２６ａ、押え片２６ａの上部両側に形成されたガイド片２６ｂ、両ガイド片２６ｂのすぐ下方に設けられＶ型バネ２５と係合する係合片２６ｃ、押え片２６ａの下部両側に形成された押圧片２６ｄを備えている。ガイド片２６ｂはアーム２４に設けられた両縁部２４ａに係合して、押え金具２６をアーム２４の上下方向移動可能に案内する。
【００１９】
次に、引き落し金具７の形状について説明する。
引き落し金具２７は線材をＵ字状に曲げ加工して形成されたものであり、腕部２７ａと両方の腕部２７ａを接続する接続部２７ｂとから構成されている。そして、腕部２７ａの先端部は内方に折り曲げられさらに先端側が照明器具本体１側へ折り曲げられている。また、両腕部２７ａの基端部は照明器具本体１から離れる方向へ折り曲げられ、外方へ突出している。
【００２０】
図４はＶ型バネ２５をアーム２４に組み付けた状態を示す斜視図である。図４に基づいてＶ型バネ５の形状について説明する。
Ｖ型バネ２５は１本のバネ線材を曲げ加工して形成され、両脚部２５ａ、両脚部２５ａの交点部にコイル状に形成されたコイル状部２５ｂ及び両脚部２５ａの先端に形成されたリング部２５ｃから構成されている。そして、両脚部２５ａの中央より若干先端寄りの位置が外方向（アーム２４を照明器具本体１に取り付けたときにおける照明器具本体１から離れる方向）でかつ両脚部２５ａが近付く方向に折り曲げられ、先端折曲部２５ｅが形成されている。
図５はアーム２４にＶ型バネ２５を組み付けた状態の側面図である。この図から分かるように、Ｖ型バネ２５の脚部２５ｂとアーム２４は所定の角度αを成して装着されている。
【００２１】
次に、再び図３に基づいて、上記のように構成されたアーム２４、Ｖ型バネ２５、押え金具２６及び引き落し金具２７の組み付け状態について説明する。
図３に示したように、Ｖ型バネ２５の両脚２５ａは押し狭められた状態でその先端折曲部２５ｅが押え金具２６のガイド片２６ｂに外方から把持されている。このときＶ型バネ２５はその両側の先端折曲部２５ｅがほぼ平行になると共に外方に向かって延出した形状になる。そのため、押え片２６ａはアーム２４側に密着した状態でアーム２４の上部に保持される。また、引き落し金具２７はその先端部がアーム２４のスリット２４ｂに挿入されると共に、押え金具２６のガイド片２６ｂ上部に係合した状態でアーム２４に取り付けられている。
このとき、Ｖ型バネ２５はその弾性により広がろうとしているが、先端折曲部２５ｅがほぼ平行であるため、押え金具２６に下向きの力を及ぼすことはない。この図３に示す状態が照明器具本体１を天井に取り付ける前のセッティング状態である。
【００２２】
次に、図３のようにセッティングされた照明装置本体１を天井に取り付ける方法及びその際の取付装置２３の動作を説明する。
セッティング状態にある照明装置本体１を天井板３０に設けた埋込穴３３に挿入する。そして、引き落し金具２７の接続部２７ｂが天井下面３２に当接し、さらに照明装置本体１を押し上げると接続部２７ｂが天井下面３２により押し下げられる。接続部２７ｂが押し下げられると、押え金具２６のガイド片２６ｂ上部に係合している引き落し金具２７の先端部が押え金具２６を引き下げることになる。
【００２３】
押え金具２６が引き下げられ、押え金具２６の係合片２６ｃがＶ型バネ２５の先端折曲部２５ｅを通過してＶ形状部に至ると、Ｖ型バネ２５の広がろうとする力が押え金具２６の係合片２６ｃに下方に向かう力を及ぼすことになる。また、このＶ形状部ではＶ型バネ２５の脚部２５ａがアーム２４と所定の角度αを成しているので、脚部２５ａに係合している押え金具２６の係合片２６ｃはその両端部の上部側がＶ型バネ２５によって内方（照明器具本体１側方向）に押されることになる。
その結果、押え金具２６の押え片２６ｂの下端部がアーム２４から浮き上がることになる。すなわち、押え金具２６の係合片２６ｃがＶ型バネ２５のＶ形状部に至った状態では、Ｖ型バネ２５は押え片６ａの下端部をアーム２４から離れる方向に付勢すると共に押え金具２６を下方へ移動させる方向にも付勢することになる。
【００２４】
押え金具２６はＶ型バネ２５の付勢力によって押え片２６ａの下端部をアーム２４から浮き上がらせた状態でアーム２４に沿って降下して押え片２６ａの下端部が天井板３０の上面３１に当接すると、図６に示すように押え片２６ａの下端部と照明装置本体１の外向フランジ１ｂによって天井板３０を挟持することになり、照明装置本体１は天井に取り付けられるのである。
【００２５】
また、本実施の形態においては押え片６ａの下端部をアーム２４から離れる方向に付勢すると共に押え金具２６を下方へ移動させる方向にも付勢する手段としてＶ型バネ２５を使用した例を示したが、本発明はこれに限られるものではなく他の手段であってもよい。ただ、Ｖ型バネ２５を用いた場合には構造が簡単であり、なおかつ両脚５ａの開脚度やバネ材の湾曲度によって付勢力を容易に調整でき便宜である。
【００２６】
さらに、本実施の形態においては、引き落し金具２７の接続部２７ｂが天井下面３２により下方に押し下げられることによって、Ｖ型バネ２５の先端折曲部２５ｅによる押え金具２６の保持が解除されるようにしたので、照明器具本体１を埋込穴３３に挿入するだけで天井面に取り付けることができ、取付の操作性及び作業性のよい照明装置を得ることができる。
【００２７】
次に、上記のようにして天井面に取り付けられた照明装置の取り外し方法及びその際の取付装置２３の動作を説明する。
照明装置を取り外すには、照明装置本体１を下方へ引き下げる。このとき、押え片６ａの下端部は天井上面３１に当接した状態で押え金具２６がアーム２４上を上方に移動する。そして、押え金具２６の係合片２６ｃがＶ型バネ２５の両脚２５ａにおける折曲部を通過し、先端折曲部２５ｅに至ると押え金具２６のＣ型部が先端折曲部２５ｅに沿って外方に移動し、図３に示したように押え片２６ｂはアーム２４側に密着する。このような状態になることによって、照明装置を取付開口穴１３から下方に抜き取ることができる。
このように本実施の形態１によれば、照明装置の取り外しも操作性及び作業性よく行うことができる。
【００２８】
以上のように本実施の形態１によれば、照明装置本体１を埋込穴３３に挿入するだけで、照明装置本体１の側面に取り付けられた取付金具２３がその押え金具２６と照明装置本体１の外向フランジ１ｂとで天井板３０を挟持して照明装置本体１を天井に取り付けるから、取付の操作性及び作業性がよく、従来の照明装置のように天井から吊り下げられたボルト等の吊り金具を必要とせず、そのためボルト等が照明装置本体内部に露出して見えることもないためにボルト隠しの化粧板なども不要となることにより、構成部品を最小限にでき、簡素な構造とすることができ、ランプや遮光ルーバー等も全て装着済みで照明装置本体１を取り付けることができるため、作業者の作業ミスが少なくなり、部品落下のおそれもなくなった。
また、照明装置本体内の天面にボルト用取付け穴が不要になり、天面の形状に制約が無くなったので、光制御のための反射板など従来は別パーツを取り付けていたが、天面１ａに光制御のための折り曲げ部１ｄを設けることもできた。
【００２９】
さらに、従来は照明装置本体１の取り付けの際に、ボルト取り付けの作業性を考慮して遮光ルーバーが照明装置本体から取り外せる構造としていたが、本実施の形態の取付金具２３によれば、遮光ルーバー１２を取り外す必要もないことから、遮光ルーバー１２を照明装置本体１に固定させている。
その固定方法は照明装置本体１の端部の側面の開口部１ｃに楔固定金具１５の先端側を差し込み、その先端側で遮光ルーバー１２のＶ型反射板１３の端部の折り返し片１３ａを支持させて行っている。
【００３０】
従って、Ｖ型反射板１３の端部に折り返し片１３ａを形成し、照明装置本体１の端部の側面に開口部１ｃを設け、楔固定金具１５を用意するという極めて簡単な構成で、Ｖ型反射板１３の折り返し片１３ａを照明装置本体１の開口部１ｃに位置合わせをして楔固定金具１５を開口部１ｃに差し込んで挿入すると、楔固定金具１５の先端側がＶ型反射板１３の折り返し片１３ａを支持するため、楔固定金具１５を開口部１ｃに挿入するだけで工具を使わず容易に開口部１ｃに挿入された楔固定金具１５に対してＶ型反射板１３が固定されることとなった。
また、照明装置本体１内に配設されたランプ７を交換するために、照明装置本体１から遮光ルーバー１２を取り外す場合も、照明装置本体１を天井から取り外した後に、照明装置本体１の開口部１ｃから楔固定金具１５を引き抜くだけで簡単に遮光ルーバー１２を取り外すことができる。
【００３１】
実施の形態２．
図９は本発明の実施の形態２に係る照明装置の遮光ルーバーの照明装置本体への固定直前の状態を示す斜視図、図１０は同照明装置の遮光ルーバーの照明装置本体への固定状態を示す斜視図である。
この実施の形態２は実施の形態１の第１の変型例で、楔固定金具１５を照明装置本体１の側面にネジ止めするようにしたものである。
この実施の形態２では、楔固定金具１５の拡径端部にネジ穴１６ａを有する止着片１６を設け、照明装置本体１の側面に開口部１ｃに楔固定金具１５が装着された状態で止着片１６のネジ穴１６ａと整合するネジ穴１７を設けたものである。
【００３２】
そして、照明装置本体１へ遮光ルーバー１２を固定する場合、照明装置本体１の端部の側面の開口部１ｃに楔固定金具１５の先端側を差し込み、その先端で遮光ルーバー１２のＶ型反射板１３の端部の両縁が内側にそれぞれ折り返して形成された折り返し片１３ａを支持させる。しかる後に、整合した止着片１６のネジ穴１６ａと照明装置本体１のネジ穴１７にネジ１８で螺合させ、楔固定金具１５の止着片１６をネジ１８で照明装置本体１に止着するようにしている。
このように、楔固定金具１５に設けた止着片１６をネジ１８で照明装置本体１に止着するようにしたから、楔固定金具１５が照明装置本体１から抜け落ちることが確実に防止される。
【００３３】
実施の形態３．
図１１は本発明の実施の形態３に係る照明装置の遮光ルーバーの照明装置本体への固定直前の状態を示す斜視図、図１２は同照明装置の遮光ルーバーの照明装置本体への固定状態を示す斜視図である。
この実施の形態３は実施の形態１の第２の変型例で、楔固定金具１５を照明装置本体１の側面にネジ止めするようにしたものである。
この実施の形態３では、照明装置本体１の開口部１ｃの縁部に張り出すようにネジ穴１９ａを有する止着片１９を設け、楔固定金具１５の拡径端部側の水平中央部に、照明装置本体１の側面に開口部１ｃに楔固定金具１５が装着された状態で止着片１９のネジ穴１９ａと整合するネジ穴２０を設けたものである。
【００３４】
そして、照明装置本体１へ遮光ルーバー１２を固定する場合、照明装置本体１の端部の側面の開口部１ｃに楔固定金具１５の先端側を差し込み、その先端で遮光ルーバー１２のＶ型反射板１３の端部の両縁が内側にそれぞれ折り返して形成された折り返し片１３ａを支持させる。しかる後に、整合した照明装置本体１の止着片１９のネジ穴１９ａと楔固定金具１５のネジ穴２０にネジ１８で螺合させ、楔固定金具１５をネジ１８で照明装置本体１の止着片１９に止着するようにしている。
このように、楔固定金具１５をネジ１８で照明装置本体１の止着片１９に止着するようにしたから、楔固定金具１５が照明装置本体１から抜け落ちることが確実に防止される。
【００３５】
実施の形態４．
図１３は本発明の実施の形態４に係る照明装置の遮光ルーバーの照明装置本体への固定直前の状態を示す斜視図、図１４は同照明装置の遮光ルーバーの照明装置本体への固定状態を示す斜視図である。
この実施の形態４は照明装置本体１への遮光ルーバー１２の固定の変形例を示すものである。この実施の形態４で、実施の形態１と同様の構成は同一符号を付して重複した構成の説明を省略する。
この実施の形態４では、楔固定金具１５の拡径端部に３つの抜け止め片２１を設けたものである。
【００３６】
そして、照明装置本体１へ遮光ルーバー１２を固定する場合、照明装置本体１の端部の側面の開口部１ｃに楔固定金具１５の先端側から楔固定金具１５の３つの抜け止め片２１が照明装置本体１の端部の側面に当接するまで差し込み、楔固定金具１全体で遮光ルーバー１２のＶ型反射板１３の折り返し片１３ａを支持させる。
このように、楔固定金具１５の３つの抜け止め片２１が照明装置本体１の端部の側面に当接するまで差し込み、楔固定金具１全体で遮光ルーバー１２のＶ型反射板１３の折り返し片１３ａを支持させるようにしたから、楔固定金具１５による支持部分が多くなって充分な取付固定が行われ、しかも楔固定金具１５が照明装置本体１から抜けにくくなる。
【００３７】
実施の形態５．
図１５は本発明の実施の形態５に係る照明装置の遮光ルーバーの照明装置本体への固定直前の状態を示す斜視図、図１６は同照明装置の遮光ルーバーの照明装置本体への固定状態を示す斜視図である。
この実施の形態５は照明装置本体１への遮光ルーバー１２の固定の変形例を示すものである。この実施の形態５で、実施の形態１と同様の構成は同一符号を付して重複した構成の説明を省略する。
この実施の形態５では、更に遮光ルーバー１２のＶ型反射板１３の端部内周面の対向する両側にそれぞれ内側に向けて水平に突出するように金具支持片１３ｂを設けたものである。
【００３８】
そして、照明装置本体１へ遮光ルーバー１２を固定する場合、Ｖ型反射板１３の折り返し片１３ａを照明装置本体１の開口部１ｃに位置合わせをし、楔固定金具１５の先端側を開口部１ｃに差し込んで挿入すると、楔固定金具１５の先端がＶ型反射板１３の折り返し片１３ａを支持すると共に、その楔固定金具１５の先端がＶ型反射板１３の折り返し片１３ａと金具支持片１３ｂとで挟持状態となるため、楔固定金具１５を開口部１ｃに挿入するだけで工具を使わず容易に開口部１ｃに挿入された楔固定金具１５に対してＶ型反射板１３が上下動及び左右動することなく堅固に固定されることとなり、輸送時、施工時及びランプ交換時に照明装置本体１にこすれキズが発生するのを防止する。
また、照明装置本体１内に配設されたランプを交換するために、照明装置本体から遮光ルーバー１２を取り外す場合も、照明装置本体１を天井から取り外した後に、照明装置本体１の開口部から楔固定金具１５を引き抜くだけで簡単に遮光ルーバー１２を取り外すことができる。
【００３９】
実施の形態６．
図１７は本発明の実施の形態６に係る照明装置の遮光ルーバーの照明装置本体への固定直前の状態を示す斜視図、図１８は同照明装置の遮光ルーバーの照明装置本体への固定状態を示す斜視図である。
この実施の形態６は、実施の形態５の第１の変型例で、楔固定金具１５を照明装置本体１の側面にネジ止めするようにしたものである。
この実施の形態６では、照明装置本体１の開口部１ｃの縁部に張り出すようにネジ穴１９ａを有する止着片１９を設け、楔固定金具１５の拡径端部側の水平中央部に、照明装置本体１の側面に開口部１ｃに楔固定金具１５が装着された状態で止着片１９のネジ穴１９ａと整合するネジ穴２０を設けたものである。
【００４０】
そして、照明装置本体１へ遮光ルーバー１２を固定する場合、照明装置本体１の端部の側面の開口部１ｃに楔固定金具１５の先端側を差し込んで挿入すると、楔固定金具１５の先端がＶ型反射板１３の折り返し片１３ａを支持すると共に、その楔固定金具１５の先端をＶ型反射板１３の折り返し片１３ａと金具支持片１３ｂとで挟持する。
しかる後に、整合した照明装置本体１の止着片１９のネジ穴１９ａと楔固定金具１５のネジ穴２０にネジ１８で螺合させ、楔固定金具１５をネジ１８で照明装置本体１の止着片１９に止着するようにしている。
このように、楔固定金具１５をネジ１８で照明装置本体１の止着片１９に止着するようにしたから、楔固定金具１５が照明装置本体１から抜け落ちることが確実に防止される。
【００４１】
実施の形態７．
図１９は本発明の実施の形態７に係る照明装置の遮光ルーバーの照明装置本体への固定状態を示す斜視図である。
この実施の形態７は、実施の形態５の第２の変型例で、楔固定金具１５を照明装置本体１の側面にネジ止めするようにしたものである。
この実施の形態７では、楔固定金具１５の拡径端部にネジ穴を有する止着片１６を設け、照明装置本体１の側面の開口部１ｃに楔固定金具１５が装着された状態で止着片１６のネジ穴と整合するネジ穴を設けたものである。
【００４２】
そして、照明装置本体１へ遮光ルーバー１２を固定する場合、照明装置本体１の端部の側面の開口部１ｃに楔固定金具１５の先端側を差し込んで挿入すると、楔固定金具１５の先端がＶ型反射板１３の折り返し片１３ａと金具支持片１３ｂとで挟持される。
しかる後に、整合した止着片１６のネジ穴と照明装置本体１のネジ穴にネジ１８で螺合させ、楔固定金具１５の止着片１６をネジ１８で照明装置本体１に止着するようにしている。
このように、楔固定金具１５に設けた止着片１６をネジ１８で照明装置本体１に止着するようにしたから、楔固定金具１５が照明装置本体１から抜け落ちることが確実に防止される。
【００４３】
実施の形態８．
図２０は本発明の実施の形態８に係る照明装置の遮光ルーバーの照明装置本体への固定直前の状態を示す斜視図、図２１は同照明装置の遮光ルーバーの照明装置本体への固定状態を示す斜視図である。

この実施の形態８では、更に楔固定金具１５の後端側上部に先端側に対して略平行に延出させた挟持片４１を設けたものである。
【００４４】
そして、遮光ルーバー１２を照明装置本体１に固定する場合、Ｖ型反射板１３の折り返し片１３ａを照明装置本体１の開口部１ｃに位置合わせをし、楔固定金具１５を開口部１ｃに差し込んで挿入すると、楔固定金具１５の先端と後端側上部に先端側に向けて延出させて設けられた挟持片４１とでＶ型反射板１３の折り返し片１３ａを挟持することとなるため、楔固定金具１５を開口部１ｃに挿入するだけで工具を使わず容易に開口部１ｃに挿入された楔固定金具１５に対してＶ型反射板１５が上下動及び左右動することなく堅固に固定されることとなり、輸送時、施工時及びランプ交換時に照明装置本体１にこすれキズが発生するのを防止する。
また、照明装置本体１内に配設されたランプを交換するために、照明装置本体から遮光ルーバー１２を取り外す場合も、照明装置本体１を天井から取り外した後に、照明装置本体１の開口部から楔固定金具１５を引き抜くだけで簡単に遮光ルーバー１２を取り外すことができる。
なお、この実施の形態８では、楔固定金具１５としているが、先端側が先細りとならない固定金具であっても実施し得ることは勿論である。

Moreover, the base end part of both the arm parts 27a is bent in the direction away from the lighting fixture main body 1, and protrudes outward.
[0020]
FIG. 4 is a perspective view showing a state in which the V-shaped spring 25 is assembled to the arm 24. The shape of the V-shaped spring 5 will be described with reference to FIG.
The V-shaped spring 25 is formed by bending a single spring wire, and both legs 25a, a coiled portion 25b formed in a coil shape at the intersection of both legs 25a, and a ring formed at the ends of both legs 25a. It is comprised from the part 25c. Then, the position slightly closer to the tip than the center of both legs 25a is bent outward (in the direction away from the luminaire main body 1 when the arm 24 is attached to the luminaire main body 1) and in the direction in which both legs 25a approach, A bent portion 25e is formed.
FIG. 5 is a side view of the arm 24 with the V-shaped spring 25 assembled thereto. As can be seen from this figure, the leg portion 25b of the V-shaped spring 25 and the arm 24 are mounted at a predetermined angle α.
[0021]
Next, referring to FIG. 3 again, the assembled state of the arm 24, the V-shaped spring 25, the presser fitting 26, and the drop-off fitting 27 configured as described above will be described.
As shown in FIG. 3, both legs 25 a of the V-shaped spring 25 are gripped from the outside by the guide piece 26 b of the presser fitting 26 with the bent end portions 25 e thereof being pressed and narrowed. At this time, the V-shaped spring 25 has a shape in which the tip bent portions 25e on both sides thereof are substantially parallel and extend outward. Therefore, the presser piece 26a is held on the upper portion of the arm 24 in a state of being in close contact with the arm 24 side. The tip of the drop-off fitting 27 is inserted into the slit 24b of the arm 24 and attached to the arm 24 in a state of being engaged with the upper part of the guide piece 26b of the presser fitting 26.
At this time, the V-shaped spring 25 is going to expand due to its elasticity, but since the tip bent portion 25e is substantially parallel, no downward force is exerted on the presser fitting 26. The state shown in FIG. 3 is a setting state before the lighting fixture body 1 is attached to the ceiling.
[0022]
Next, a method for attaching the lighting device body 1 set as shown in FIG. 3 to the ceiling and the operation of the attachment device 23 at that time will be described.
The lighting device main body 1 in the setting state is inserted into the embedding hole 33 provided in the ceiling plate 30. Then, the connecting portion 27b of the drop-off fitting 27 comes into contact with the ceiling lower surface 32, and when the lighting device body 1 is further pushed up, the connecting portion 27b is pushed down by the ceiling lower surface 32. When the connecting portion 27 b is pushed down, the tip end portion of the drop-off fitting 27 engaged with the upper part of the guide piece 26 b of the press-down fitting 26 pulls down the hold-down fitting 26.
[0023]
When the presser fitting 26 is pulled down and the engaging piece 26c of the presser fitting 26 passes through the tip bent portion 25e of the V-shaped spring 25 and reaches the V-shaped portion, the force for spreading the V-shaped spring 25 is increased. A downward force is applied to the 26 engagement pieces 26c. Further, in this V-shaped portion, since the leg portion 25a of the V-shaped spring 25 forms a predetermined angle α with the arm 24, the engagement pieces 26c of the presser fitting 26 engaged with the leg portion 25a are at both ends thereof. The upper side of the part is pushed inward (in the direction of the lighting fixture body 1) by the V-shaped spring 25.
As a result, the lower end portion of the presser piece 26 b of the presser fitting 26 is lifted from the arm 24.
