【００１６】
【実施の形態】
本発明に係る実施の形態の全体斜視図を図１に、その分解斜視図を図２に、その正面図を図３（ａ）に、その右側面図を図３（ｂ）に、その側面断面図を図４に、その灯具の側面断面図を図５に示す。
【００１７】
以下、図１乃至図５を参照して説明する。
【００１８】
この電気スタンドは、ランプ（ここでは、片口金蛍光灯）４が着脱自在に装着されるランプソケット（以下、ソケットと呼ぶ。）１３を備えた灯具５と、その先端部分に灯具５が嵌着される支柱３と、支柱３の基端が固定されて机上等に載置されるベース１とで構成されるものである。
【００１９】
ベース１には先端に電源プラグを備える電源コード９が設けられており、電源プラグと電源コード９とを介して供給される商用電源は、ランプ４を点滅させるためのタッチ式のスイッチ２を介して、ベース１に納装されている点灯回路２７に供給されるとともに、アーム２２の内部に挿通された電線４０によりソケット１３及びランプ４へと供給される。 灯具５は、上セード１１、下セード１２、反射板１５、ソケット１３等からなり、上セード１１の開口下面を略覆う様に下セード１２と金属製の反射板１５とが配設されている。下セード１２と反射板１５とは、上セード１１の内壁面であってその短手方向に略平行に設けた短手方向リブ３２によって位置決めされる。上セード１１の背面（図２中の支柱３側）略中央には穴部３１が設けられている。上セード１１の下面には３つのネジ受け部が設けられ、２つのねじ１７を下セード１２に設けた貫通穴３３を介してネジ受け部にねじ込むことにより下セード１２を上セード１１の下面側に固定配置している。また、１つのねじ１８をランプ支持バネ１６に設けた貫通穴及び反射板１５に設けた貫通穴を介してネジ受け部にねじ込むことにより反射板１５、ランプ支持バネ１６を上セード１１の下面側に固定配置している。
【００２０】
反射板１５はランプ４の光を灯具５の下方へ反射するものである。ソケット１３は下セード１２に設けたソケット台３４に設置される。
【００２１】
支柱３は、内部に電線４０を通線可能なアーム２２が挿入されており、アーム２２を納装するように樹脂製のパイプで覆われている。その樹脂製パイプは、灯具５に近い上半分側がプレシキブルパイプ状になっており、その部分を伸縮することにより灯具５を自在に動かすことができる。
【００２２】
ベース１は、その一部に略半円筒状の凸部８を設けてなる底面開口のカバー３０と、カバー３０の底面側を覆うように設けられる底板２５とからなる。底板２５は、底板２５に設けたネジ穴を介してカバー３０の内壁面に設けたネジ受部（図示せず）にネジ２８をねじ込むことによりカバー３０に固定される。底板２５には、点灯ブロック２７とスイッチ２とが絶縁板を介してネジで固定されている。また、底板２５に設けた穴部から臨むように転倒スイッチ２６が設けられている。カバー３０の背面側（図２中の支柱３側）には、アーム２２の下端部が貫通する貫通穴２３が形成され、アーム２２の基端部に形成されたネジ部を貫通穴２３に貫通させてから、カバー３０の内部でアーム２２のネジ部にナット及びワッシャ４３を螺着させることにより、アーム２２（及び支柱３）をベース１に固定する。
【００２３】
スイッチ２は、凸部８に設けた穴部２４から臨むように設けられ、スイッチ２をオンオフすることによりランプ４を点滅させるものである。転倒スイッチ２６は、転倒スイッチ２６がオフされる程度に照明器具が傾くと、ランプ４を消灯させるものである。
【００２４】
アーム２２の先端部には、取付金具２０が上セード１１の短手方向に略平行な向きに装着されている。この取付金具２０は、略板状の板金を略階段状に曲折し、２つの平面の各々の略中央にはネジ穴が設けられてなる。また、上セード１１の内壁面略中央には、支持金具１４が、上セード１１の長手方向に略平行な向きにネジ１９により装着されている。この支持金具１４は、略板状の板金であり、３つのネジ穴が略等間隔で設けられ、両端の２つのネジ穴は、支持金具１４を上セード１１の内壁面に装着する為のものである。
【００２５】
そして、取付金具２０の先端側に設けたネジ穴と支持金具１４の略中央に設けたネジ穴とを介して、上セード１１の内壁面に設けたネジ受け部（図示しない）にネジ２１をねじ込むことにより、取付金具２０と支持金具１４とを互いに固定する。また、取付金具２０の他方のネジ穴を介して上セード１１の支柱３近くの内壁面に設けたネジ受け部（図示しない）にネジ２１をねじ込む。よって、取付金具２０の先端部を上セード１１の内壁面に固定することができ、取付金具２０及び支持金具１４を介して、支柱３の先端部に灯具５を安定して嵌着することができる。
【００２６】
上セード１１の内壁面の長手方向には反射板１５を位置決めする２つのリブ３７が形成されており、リブ３７に反射板１５の端部を当接することにより反射板１５を配設する。このリブ３７の下端部は上セード１１の内壁面側に傾斜し、反射板１５の長手方向端部もリブ３７の該傾斜に沿った角度で折り曲げられて形成されているので、反射板１５を上セード１１に取付ける際には、上セード１１と反射板１５とが互いに適正に係合しあう。
【００２７】
以上の様に構成することにより、上セード１１と反射板１５との間の隙間を小さくすることができる。また、仮に、上セード１１や反射板１５に反りや歪みなどが発生しても、上セード１１と反射板１５とが互いに食い込むように係合しあうので、互いに適合に係合しあうことができ、該反りや歪みなどを矯正することができる。また、反射板１５の配置位置を簡単に合せることができ、反射板１５の取付バラツキを抑制することができる。
【００２８】
なお、本発明に適応するものであれば、照明器具の構造は前述のものに限らず何でも良い。
【００２９】
【発明の効果】
請求項１乃至請求項５に記載の発明によれば、反射板を確実に上セードの内壁面に固定することが可能な照明器具を提供できる。
