Description

【０００１】
【発明の属する技術分野】
この発明は、照明器具の反射板が器具本体から落下するのを防止する落下防止体に関するものであり、落下防止体がアース機能を有するものに関する。
【０００２】
【従来の技術】
従来の照明器具は、次のようなものである。
照明器に、反射板の器具本体からの落下を防止する落下防止体が用いられている場合は、この落下防止体を導電性とすることにより、器具組立時の組立工数および部品点数を増加させることなく、器具本体と反射板との電気的接続を容易かつ確実に確保できる。
すなわち、落下防止体は、導電性を有する金属製の鎖など紐状の部材で形成された落下防止チェーンであり、基部が器具本体のシャーシに電気的かつ機械的に接続されているとともに、先端部に設けた導電性を有する金属フック部を、反射板のバッフルに形成した紐孔に引っ掛けることにより、落下防止体を介して、器具本体と反射板との電気的接続を確保できる。
なお、落下防止体は、チェーンに限らず、単線の紐状線、線からなる紐状線などで構成することもできる（例えば、特許文献１参照。）。

【発明が解決しようとする課題】
しかしながら、特許文献１の照明器具においては、落下防止体８１は落下防止機能とアース機能を併せ有するものではあるが、接地の信頼性、落下防止の信頼性及び照明器具の取付時の作業の容易さは、必ずしも総て併せて満足できるものではなかった。
【０００５】
本発明は、接地の信頼性及び落下防止の信頼性が高く、しかも照明器具取付作業時の取付作業性が良いアース機能付き落下防止体を有する照明器具を得ることを目的とする。
【０００６】
【課題を解決するための手段】
本発明による照明器具は、一端が器具本体に固定され、他の一端は長形状のピンが固定され、ピンが反射板の折返し部に収納された後、折返し部がつぶされ、ピンが反射板に固定されることにより、反射板を器具本体に機械的かつ電気的に接続させた落下防止体を有するものである。
【０００７】
【発明の実施の形態】
実施の形態１．
本発明の実施の形態１の照明器具を図に基づいて説明する。
図１は、実施の形態１の照明器具の概略の断面図であり、反射板を落下防止体で吊り下げた図である。
本実施の形態の照明器具は、器具本体１、安定器等の電気部品３、反射板２、落下防止体４及びランプである蛍光灯５を取付けるランプソケット等から構成される。
ここで、器具本体１は、天板１ａ、下方に開くように延びる左右の側板１ｂ、１ｂ及び両端部の端板１ｃ、１ｃからなり、下面が開放された箱状のものである。
また、天板１ａの幅方向の中央部の長手方向に、安定器、電源端子台（図示省略）等の電気部品３が取り付けられる。
また、器具本体１の長手方向の全長に亘って断面Ｖ字状の反射板２（反射板２は、例として断面Ｖ字状のものを挙げているが、箱型のもの等反射板であればよい）が照明器具本体１に電気部品３を覆うように装着される。
さらに、器具本体１の幅方向に各一対のランプ取付け用ソケット（図示省略）が設けられ、反射板２の下部で、器具本体の長手方向に対向するランプ取付け用ソケット間に蛍光灯５、５が取り付けられる。
落下防止体４は、反射板２を器具本体１に接続し、反射板２の落下防止と反射板２を器具本体１を介して接地するアース機能とを有するものである。
【０００８】
次に、器具本体１と反射板２をアース機能付きの落下防止体４で接続することを説明する。
図２は、器具本体と反射板をアース機能付きの落下防止体で接続する落下防止体の取付を説明する図である。
図において、固定ねじ７が、器具本体１又は反射板２の表面からねじ部が突出するようにねじ込み固定、溶接固定等で設けられる。落下防止体４の一端は、反射板２又は器具本体に固定されており、他の一端の金属製のフック６は、固定ねじに引っ掛け、上からナット、例えば蝶ナットをねじ込むことにより着脱可能に固定される。
落下防止体４は、フック６も含めて導電部材からなり、反射板２は、落下防止体４により器具本体１に吊り下げられ、落下が防止できるとともに、器具本体１を介して接地される。
【０００９】
本実施の形態によると、導電部材からなる落下防止体４の一端はあらかじめ器具本体１または反射板２に固定され、他の一端であるフックは反射板２又は器具本体１の固定された固定ねじとナットで固定されるので、落下防止とともに、確実に接地される。また、照明器具の取付工事においては、落下防止体４のフック６をねじ止めするだけでよく、作業が極めて容易である。しかも、反射板２を一旦取付けた後、取外す際にもねじ固定のため簡単に取外すことが可能である。
【００１０】
図３は、落下防止体の取り付けの別の例を説明する図であり、固定ナット９が、器具本体１又は反射板２の表面からナット部が突出するように溶接固定等で設けられる。落下防止体４の一端は、反射板２又は器具本体に固定されており、他の一端に取付けられたフック６は、つまみねじ１０に引っ掛け、固定ナットにねじ込むことにより着脱可能に固定される。
このようにしても、上記と同様な効果が得られる。
【００１１】
図４は、落下防止体の取り付けの更に別の例を説明する図であり、固定ナットであるねじ取付部１１が、器具本体１又は反射板２の表面に直接設けられる。
落下防止体４の一端は、反射板２又は器具本体１に固定されており、他の一端は、ねじに取り付けられており、このワイヤ付きねじをねじ取付部１１にねじ込むことにより着脱可能に固定される。
このようにしても、上記と同様な効果が得られる。
【００１２】
図５は、落下防止体の一端の丸フックを示す図であり、図２、３に示した落下防止体４の一端のフック６を丸フック６ａとしたものである。図２及び図３のねじ径に合せることにより、より確実な接続ができる。
また、図６は、落下防止体をチェーンとし、一端に丸フックを取付けたものを示す図であり、落下防止体をチェーン４ａとし、一端に丸フック６ａを取付たものである。
【００１３】
本実施の形態は、落下防止体４の両端ともに、フック６または丸フック６ａを取付け、器具本体１及び反射板２の両方に、固定ねじ７、固定ナット９またはねじ取付部１１を設け、照明器具の取付け時に、ナット８又はつまみねじ１０により、ねじ止めすることにより、器具本体１と反射板２を接続してもよい。
【００１４】
実施の形態２．
実施の形態２の照明器具を説明する。但し、落下防止体４の取付けの他は、実施の形態１と同じであるので、主としてこの相違点について説明する。
図７は、アース機能付の落下防止体の取付けを説明する図であり、図７（ａ）は、落下防止体の一端のピンを反射板の折返し部（カール部）に取付けた要部を示す図であり、図７（ｂ）は、落下防止体の一端のピンを反射板の折返し部に取付た状態を折返し部の断面側から見た図である。
図において、反射板２、例えばＶ字状の反射板２の上端部は長手方向に沿って、内側にカールする折返し部２ｂが形成されており、この折返し部２ｂに切欠き２ｃを設ける。また、２個の切欠き２ｃ、２ｃで分割された巻き部２ｂ（図７に示すように、反射板２の端部の折返し部２ｂの場合は、１個の切欠き２ｃで分割された折返し部２ｂ）に穴ｄを設ける。
落下防止体４は、一端をあらかじめ器具本体１に固定し、他端には、折返し部２ｂに収まり、導電材からなる長形状のピン１３を固定しておく。
【００１５】
照明器具の取付け作業時に、他の一端のピン１３を反射板２の折返し部２ｂに収納し、折返し部２ｂをつぶすことにより、反射板２とピン１３を確実に接触させる。この際、折返し部２ｂの穴２ｄを落下防止体４が通るようにする。
また、ピン１３の表面に突起を設ければ、つぶしたとき、より確実に接触する。
さらに、ピン１３を長手方向にテーパを有する柱状体又は管状体とし、折返し部２ｂの端部の開口部からピン１３の細い方を先にして挿入する。ここで、ピン１３の断面形状、テーパを巻き部２ｂの収容部に対して適当にすることで、巻き部２ｄをつぶさなくても、両者の接触を確実にでき、その分、手数が減る。この場合も、接触をより確実にするために、ピン１３の表面に突起を設けてもよい。
【００１６】
本実施の形態の照明器具は、反射板２の上端部の長手方向に沿って折返し部２ｂが形成され、落下防止体４は、一端が器具本体１に固定され、他の一端は長形状のピン１３が固定され、該ピン１３が反射板２の折返し部２ｂに収納された後、該折返し部２ｂがつぶされ、ピン１３が反射板２に固定されることにより、反射板２を器具本体１に機械的かつ電気的に接続させたので、反射板２を確実に接地及び落下防止でき、しかも照明器具取付作業時の取付作業性が良い落下防止体を有する照明器具を得ることができる。
【００１７】
図８及び図９は、それぞれ、落下防止体の取付けを説明する別の図、さらに別の図である。
これらの落下防止体４においては、一端は器具本体１または反射板２に固定しておき、他の一端にピン１３を取付けておく。落下防止体４の一端が固定していない反射板２または器具本体１に、それぞれの図に示すように、立上り部１４ａと切起し穴１４ｂからなる切起し部（一箇所支持の切起し部）１４、立上り部１６ａと切起し穴１６ｂからなる切起し部（二箇所支持の切起し部）１６を形成し、またこの近傍に穴１５を設ける。
【００１８】
照明器具の取付け作業時に、それぞれ、落下防止体４を切起し部１４の立上り部１４ａ、切起し部１６の立上り部１６ａを通して、他の一端のピン１３を、反射板２または器具本体１の穴１５に小さい方の断面側からはめ込み、大きい方の断面側で、穴１５から抜けないようにする。そして、ピン１３と立上り部１４ａ間、ピン１３と立上り部１６ａ間、それぞれの間で落下防止体４の弛みをなくし、ピン１３がそれぞれの器具本体１または反射板２に密着するように張った状態で、それぞれ、立上り部１４ａ、立上り部１６ａをつぶし、落下防止体４との電気的接続をとる。
【００１９】
このように、ピン１３を器具本体１または反射板２に密着させ、また、立上り部１４ａ、１６ａをつぶすことにより、落下防止体４を器具本体１または反射板２に接触させ、反射板２を器具本体１に機械的に、かつ電気的に接続させる。
【００２０】
本実施の形態の照明器具においては、反射板２又は器具本体１に穴部１５と切起し部１４、１６が形成され、落下防止体４は、一端が器具本体１又は反射板２に固定され、他の一端はピン１３が固定され、該ピン１３が切起し部１４、１６の立上り部１４ａ、１６ａを通って、穴部１５に挿入された後、切起し部１４、１６の立上り部１４ａ、１６ａがつぶされ、ピン１３が反射板２に固定されることにより、反射板２を器具本体１に機械的かつ電気的に接続させたので、反射板２を確実に接地及び落下防止でき、しかも照明器具取付作業時の取付作業性が良い落下防止体を有する照明器具を得ることができる。
【００２１】
また、本実施の形態の照明器具においては、図７、８、９に示す照明器具の落下防止体いずれも、器具本体１又は反射板２に固定ねじ７又は固定ナット９、１１が固定され、落下防止体４の一端は、器具本体１又は反射板２に固定される代わりに、ナット８又はねじ１０、１２により、器具本体１又は反射板２に固定された固定ねじ７又は固定ナット９、１１に挟み固定されるようにしてもよく、このようにすれば、反射板２を一旦取付けた後、取外す際にもねじ固定のため簡単に取外すことが可能である。
【００２２】
実施の形態３．
実施の形態３の照明器具の落下防下体４の取付けを説明する。落下防止体４の取付けの他は、実施の形態１と同じであるので、主としてこの相違点について説明する。

また、器具本体１または反射板２の落下防止体４の他の一端を固定する場所に長円状の穴１５を形成する。
【００２３】
照明器具の取付け作業時に、他の一端のラッチ１８の回転部１８ｂを、器具本体１または反射板２に形成した穴１５に長手方向を合せて挿入する。そして、つまみ部を９０度回転し抜けないようにして、基部１８ａと回転部１８ｂとで器具本体１または反射板２を挟むことにより、クイックラッチ１８と器具本体１または反射板２が電気的に接触する。
本実施の形態の照明器具によれば、落下防止体４は、一端が器具本体１又は反射板２に固定され、他の一端はラッチ１８が接続され、反射板２又は器具本体１に形成された穴部１５にラッチ１８の回転部１８ｂが挿入され、抜き取りできないように回転され固定されることにより、反射板２を器具本体１に機械的かつ電気的に接続したので、反射板２を確実に接地及び落下防止できるとともに、照明器具１取付作業時の取付作業性が良い落下防止体を有する照明器具１を得ることができる。さらに、一旦取付けた反射板２を自在に着脱できる。
【００２４】

【００２６】
実施の形態５．
