Description

【０００１】
【発明の属する技術分野】
この発明は、器具本体の下面開口部に取付けられる照明器具の光制御部材の取付構造に関する。
【０００２】
【従来の技術】
図１３は、例えば、特開平６−１１９８０６号公報に示された従来の光制御部材を有する照明器具の斜視図、図１４は光制御部材７の取付け用のラッチの断面図、図１５はラッチの反対側の取付部の断面図である（従来例１）。図１３において１は器具本体、３１は下端枠部、２は反射板、４は蛍光ランプ、３３は天井材（破断面）、３５は光制御部材である。図１４において、３６は本体器具１の下端枠部３１側に設けられた光制御部材３５の係止用の角穴、４３は光制御部材３５の長手方向片側の外面下側固定されたラッチ、４１は揺動可能に設けられた係止金具であり操作部３９とガイド部４０を有する。３７は回転軸、３８は係止金具４１を外方に回転させるねじりバネである。図１５において、４５は光制御部材３５の長手方向片側に取付けられた係止片である。
【０００３】
この構成において、光制御部材３５を装着するときは、光制御部材３５の係止片４５を器具本体１の角穴３６に係止した後、光制御部材３５を回転させるようにして器具本体１の内側に押し上げると、器具本体１の下端枠部３１に係止金具４１のガイド部が当り、さらに光制御部材３５を押し上げると、ガイド部４０が器具本体１内面を摺動し、角穴３６の所でねじりバネ３８により角穴３６に係合され、光制御部材３５が装着される。そして、光制御部材３５外すときは操作部３９を操作し、ガイド部４０を角穴３６から外し、次に、係止片４５を角穴３６から取り外す。
【０００４】
図１６は、例えば、実登２５８１０３４号公報に示された従来の照明器具の光制御部材の取付構造の部分斜視図、図１７は取付構造の断面図である（従来例２）。図１６、１７において、５１は器具本体、５２は付属部材である光制御部材、６１は器具本体５１のエンドプレート、５９はランプソケット、５３はエンドプレート６１に設けられた係止孔、５４は光制御部材５２に設けられ、係止孔５３に挿入される係止片であり、固定具５５に取付けられている。５７は位置決め金具６０の両脚片の間に配設された係留体であり、円柱状の係止体５７ａと軸部５７ｂからなる。５６は係留体５７と固定具５５を結び付ける紐状体である。
【０００５】
この構成において、光制御部材５２を装着するときは、器具本体５１の係止孔５３に光制御部材５２の係止片５４を挿入することによって装着するが、このとき、係留体５７を係止孔５３に通して位置決め金具６０の間に配置してから紐状体５６を引っ張って係留体５７が位置決め金具６０の両脚片の間に収め、光制御部材５２が器具本体５１からの落下するのを防止している。
【０００６】
【発明が解決しようとする課題】
しかしながら、従来例１では光制御部材３５の長手方向側と照明器具本体５１の開口部の長手方向側に間隙がある場合は、長手方向側で取付ができないという問題があった。また、ラッチ４３の操作部３９が下から見えるので外観が悪いという問題があった。
また、光制御部材３５の長手方向に係止金具４１、係止片４５があるので、光制御部材３５の長手方向の枠が大きくなり、光を有効に出す器具本体１の開口部面積が狭くなるという問題があった。
また、従来例２では、長手方向側でなく、短手方向側に係止孔５３と係止片５４が設けられており、照明器具本体１の開口部の長手方向側に間隙があっても取付ができるが、係止片５４を操作するために、光制御部材５２の下面に操作部があるため、操作部が下から見え外観が悪いという問題があった。
また、蛍光ランプを交換するときは、光制御部材５２を紐状体５６により器具本体５１に吊り下げたままなので、安定した作業を行うことができないという問題があった。
【０００７】
この発明は上記のような問題点を解消するためになされたもので、簡単な構成により、蛍光ランプの交換作業を容易に行うことができ、器具本体の下面の開口部に取付けられる光制御部材を着脱するための取付構造を見えないようにして外観がよく、光を有効に出す開口部面積を大きくできる照明器具の光制御部材の取付構造を提供することを目的とする。
【０００８】
【課題を解決するための手段】
この発明に係る照明器具の光制御部材の取付構造は、器具本体の下面開口部に取付けられる照明器具の光制御部材の取付構造において、前記光制御部材は、長手方向の両側面側に断面が略Ｖ字形状のＶ字形枠部を有し、前記Ｖ字形枠部の両方が前記器具本体の反射板から離間して設けられ、前記光制御部材の前記Ｖ字形枠部の両端部内に各々設けられ、挿入部を有する係止手段と、前記器具本体の両端部に設けられ、前記係止手段の前記挿入部と各々係合する係止孔と、を備え、前記Ｖ字形枠部のうち、一方の前記Ｖ字形枠部に設けられた前記係止手段を前記係止孔に係合したまま、これを回転軸とし、他方の前記Ｖ字形枠部に設けられた前記係止手段を前記係止孔から外すことにより、前記光制御手段を回動可能としたものである。
【０００９】
また、光制御部材は、Ｖ字形枠部の間に長手方向に直角に設けられた複数の光制御片と、光制御部材の長手方向の両端部に設けられた各々一対の遮蔽板の上部両側に各々設けられた支持孔と、を備え、係止手段は、両端部が前記一対の遮蔽板の支持孔に各々摺動自在に挿入され、器具本体の端部側の一端を挿入部、他端が支持部とし、中間に突設された操作部と、前記挿入部を前記器具本体の前記端部側に付勢する付勢手段と、を備える。
【００１０】
また、器具本体の下面開口部に取付けられる照明器具の光制御部材の取付構造において、前記光制御部材は、長手方向の両側面側に断面が略Ｖ字形状のＶ字形枠部を有し、前記Ｖ字形枠部の一方が前記器具本体の反射板から離間し、他方が前記器具本体の反射板に接して設けられ、前記光制御部材の前記Ｖ字形枠部の両端部内に各々設けられ、挿入部を有する係止手段と、前記器具本体の両端部に設けられ、前記係止手段の前記挿入部と各々係合する係止孔と、を備え、前記Ｖ字形枠部のうち、一方の前記Ｖ字形枠部に設けられた前記係止手段を前記係止孔に係合したまま、これを回転軸とし、他方の前記Ｖ字形枠部に設けられた前記係止手段を前記係止孔から外すことにより、前記光制御手段を回動可能としたものである。
【００１１】
また、光制御部材は、Ｖ字形枠部の間に長手方向に直角に設けられた複数の光制御片と、光制御部材の長手方向の両端部に設けられた各々一対の遮蔽板の反射板から離間した側の上部に各々設けられた支持孔と、前記光制御部材の長手方向の両端部に設けられた各々一対の遮蔽板の下部の前記反射板に接した側の一部をＶ字形枠部の内側側面部から各々突設し、各々支持孔を有する一対の支持部と、を備え、
前記反射板から離間した側のＶ字形枠部の係止手段は、両端部が前記一対の遮蔽板の支持孔に各々摺動自在に挿入され、前記器具本体の端部側の一端を挿入部、他端を支持部とし、中間に突設された操作部と、前記挿入部を前記器具本体の前記端部側に付勢する付勢手段と、を備え、前記反射板に接した側のＶ字形枠部の係止手段は、両端部が前記一対の支持部の支持孔に各々回動・摺動自在に挿入され、器具本体の端部側の一端を挿入部、他端を支持部とし、中間を操作部とする略Ｕ字形状の線バネとしたものである。
【００１２】
また、反射板から離間した側のＶ字形枠部の係止手段の挿入部の光制御部材の外側方向にテーパ部を設け、係止孔はテーパ部に対応した形状としたものである。
【００１３】
また、光制御部材は、Ｖ字形枠部の間に長手方向に直角に設けられた複数の光制御片と、光制御部材の長手方向の両端部に設けられた各々一対の遮蔽板の下部両側の一部をＶ字形枠部の内側側面部から各々突設し、各々支持孔を有する一対の支持部と、を備え、係止手段は、両端部が前記一対の支持部の支持孔に各々回動・摺動自在に挿入され、器具本体の端部側の一端を挿入部、他端を支持部とし、中間を操作部とする略Ｕ字形状の線バネとしたものである。
【００１４】
また、係止手段は、Ｖ字形枠部の外側側面部の上端縁部と前記Ｖ字形枠部の外側側面部と対向する反射板の下端縁部とを結ぶ線から下方の範囲に位置するように、前記Ｖ字形枠部の内側側面部に取り付けたものである。
【００１５】
【発明の実施の形態】
実施の形態１．
図１はこの発明の実施の形態１を示す光制御部材を有する照明器具の平面図と断面図、図２は光制御部材の平面図と側面図、図３は照明器具の光制御部材の取付構造の要部斜視図、図４は図１の断面図の拡大図、図５は動作説明図である。
図１において図１（ａ）は光制御部材を有する照明器具の平面図、図１（ｂ）は断面図であり、１は器具本体、１ａ、１ｂは器具本体１のエンドプレート（端板）、２は反射板、３はソケット、４は蛍光ランプ、５は光制御部材である。
【００１６】
図２において、図２（ａ）は光制御部材の平面図、図２（ｂ）、（Ｃ）は光制御部材の側面図である。図２、３、４において６は光制御部材５の制御片、７ａ、７ｂはＶ字形枠部、６ａ、６ｂは光制御部材５の一方の端部の一対の遮蔽板、６ｃ、６ｄは光制御部材５の他方の端部の一対の遮蔽板、７１は遮蔽板６ａ、６ｂ、６ｃ、６の下部に各々一体に設けられ、ソケット３を見えないようにする下部遮蔽板、８ａ、８ｂは光制御部材５の一方の端部に設けられた係止手段である係止金具であり、一端の挿入部８０ａが遮蔽板６ａの支持孔１０、他端の支持軸部８０ｃが遮蔽板６ｂの支持孔１０に、摺動自在に支持され、中央部にＶ字形枠部７ａ、７ｂに各々設けられたガイド孔７２を通して突設された操作部８０ｂが設けられ、支持部８０ｃの外側の操作部８０ｂと遮蔽板６ｂの支持孔１０との間に係止金具８ａ、８ｂを各々をエンドプレート１ａ方向に付勢する付勢手段であるコイルバネ１１が装着されている。
【００１７】
１３ａ、１３ｂは係止金具８ａ、８ｂの挿入部８０ａが各々挿入される係止孔である。図示してないが、係止金具８ｃ、８ｄは係止金具８ａと同じ構成である。（１３ｃ）、（１３ｄ）は、エンドプレート１ａの反対側にあるエンドプレート１ｂに設けられ、係止孔１３ａ、１３ｂと対向した位置に各々設けられた係止孔を示し、係止金具８ｃ、８ｄの挿入部８０ａが各々挿入される。
【００１８】
なお、図４に示すように、係止金具８ｂは、Ｖ字形枠部７ｂの外側側面部の上端縁部ｂとＶ字形枠部７ｂの外側側面部と対向する反射板２の下端縁部ａとを結ぶ線ｃから下方の範囲に位置するように、Ｖ字形枠部７ｂの内側側部に取り付けて、器具本体１の下方から係止金具８ｂが見えないように構成されている。他の係止金具８ａ、８ｃ、８ｄ及びＶ字形枠部７ａについても同じである。
【００１９】
次に、図１〜５により動作を説明する。光制御部材５を器具本体１に装着するときは、光制御部材５の一方の係止金具８ｂの挿入部８０ａが突き出たまま、挿入部８０ａの先端をエンドプレート１ａの係止孔１３ｂに挿入し、光制御部材５の他方の係止金具８ｄの操作部８０ｂをスライドさせ挿入部８０ａを光制御部材５の内部に没入させ、挿入部８０ａがエンドプレート１ｂの係止孔１３ｄの位置に合うように光制御部材５を移動し、位置が合ったときに、操作部８０ｂを解放して挿入部８０ａが係止孔１３ｄに挿入させる。このとき、挿入されている係止金具８ｂ、８ｄを中心にして、制御部材５が吊り下がった状態となる（図５（ｃ））。
なお、係止金具８ｂ、８ｄを別々に係止孔１３ｂ、１３ｄに挿入したが、同時に挿入してもよい。
【００２０】
次に、光制御部材５の係止金具８ａ、８ｃの各々の操作部８０ｂをスライドさせ挿入部８０ａを光制御部材５の内部に没入させ、既に挿入された係止金具８ｂ、８ｄを中心にして、制御部材５を回動させ、光制御部材５の係止金具８ａの挿入部８０ａがエンドプレート１ａの係止孔１３ａ、係止金具８ｃの挿入部８０ａがエンドプレート１ｂの係止孔１３ｃの位置に各々合ったとき、各々の操作部８０ｂを解放して挿入部８０ａを各々係止孔１３ａ、１３ｃに挿入させる（図５（ａ））。
【００２１】
次に、光制御部材５を取り外すときは、光制御部材５の係止金具８ａ、８ｃの各々の操作部８０ｂをスライドさせ挿入部８０ａを光制御部材５の内部に没入させ、光制御部材５の係止金具８ａ、８ｃの挿入部８０ａを各々係止孔１３ａ、１３ｃから外すと、挿入されている係止金具８ｂ、８ｄを中心にして、制御部材５が下方に回動し（図５（ｂ））、吊り下がった状態となる（図５（ｃ））。
蛍光ランプ４を交換するときは、この状態で行い、上記のようにして光制御部材５を器具本体１に装着する。
【００２２】
光制御部材５を取外すときは、さらに、光制御部材５の係止金具８ｂ、８ｄの各々の操作部８０ｂをスライドさせ挿入部８０ａを光制御部材５の内部に没入させ、光制御部材５の係止金具８ｂ、８ｄの挿入部８０ａを各々係止孔１３ｂ、１３ｄから外す。このとき、係止金具８ｂ、８ｄのうち、一方ずつ取外してもよい。
【００２３】
以上のように、簡単な構成により、Ｖ字形枠部７ａ、７ｂのうち、例えば、一方の光制御部材５の係止金具８ｂ、８ｄを係止孔１３ｂ、１３ｄに係合したまま、これを回転軸とし、他方の光制御部材５の係止金具８ａ、８ｃを各々係止孔１３ａ、１３ｃから外すことにより、光制御部材５を回動可能としたので、蛍光ランプ４の交換作業を容易に行うことができる。
また、器具本体１の下面の開口部に取付けられる光制御部材５を着脱するための係止金具８ａ〜８ｄを見えないようにして外観をよくすることができ、また、このときの着脱操作を簡単にすることができる。
また、ソケット３が見えないので見た目をスッキリさせることができる。
また、光制御部材５の長手方向に係止金具８ａ〜８ｄを配設しないことで、光制御部材５の長手方向の枠部寸法が大きくならず、光を有効に出す器具本体１の開口部面積を大きくすることができる。
【００２４】
実施の形態２．
実施の形態１では、コイルバネにより付勢される係止金具を使用したが、本実施の形態は係止金具にＵ字形状の線バネを使用したものである。
図６は実施の形態２を示す照明器具の光制御部材の取付構造の要部斜視図である。実施の形態１の図３と同じ部分には同一の符号を付し、説明を省略する。
図６において１４ａは遮蔽板６ａの下部を延設し、支持孔１５を設けた支持部、１４ｂは遮蔽板６ａの下部を延設し、Ｖ字形枠部７ｂの内側側板を貫通させ、支持孔１５を設けた支持部、９ｂはＵ字状線ばね係止金具であり、エンドプレート１ａの下部に設けられた係止孔１３ｂに挿入されるとともに、支持部１４ａに摺動・回動自在に支持される挿入部９０ａ、中央部の操作部９０ｂ及び支持部１４ｂに摺動・回動自在に支持される支持部９０ｃから構成される。
【００２５】
図示してないが、支持部１４ａ、１４ｂはＶ字形枠部７ａ側にも設けられており、９ａは挿入部９０ａ、操作部９０ｂ及び支持部９０ｃから構成され、挿入部９０ａがエンドプレート１ａの係止孔１３ａに挿入される線バネ係止金具である。
また、図示してないが、エンドプレート１ｂとエンドプレート１ｂ側の光制御部材端部にも、係止孔１３ａ、１３ｂ、線バネ係止金具９ａ、９ｂと同じものが、同じ位置に設けられている。
この構成による動作は実施の形態１と同様であり説明を省略する。
【００２６】
以上のように、部品点数を減らした簡単な構成で、器具本体１の下面の開口部に取付けられる光制御部材５を着脱するための線ばね係止金具９ａ、９ｂ等を見えないようにして外観をよくすることができ、また、このときの着脱操作を簡単にすることができる。
また、線バネ係止金具９ａ、９ｂ等の支持部１４ａ、１４ｂを光制御部材５のＶ字形枠部７ａ、７ｂの下部に設け、係止孔１３ａ、１３ｂ等をエンドプレート１ａ、１ｂの下部に設けることができるので、光制御部材５の着脱時に、光制御部材５の回動中心軸が光制御部材５の下部となるので、反射板２と光制御部材５の間隔が狭いときでも、光制御部材５の下部が反射板２に接触するのを防ぐことができる。
【００２７】
実施の形態３．
実施の形態１ではルーバが器具本体の反射板の中心部に配設されていたが、本実施の形態はルーバが反射板の片側に接するように配設したものであり、光制御部材５が反射板２に接する側に、実施の形態２で示した線バネ係止金具を用い、反対側に実施の形態１で示した係止金具を用いたものである。
図７はこの発明の実施の形態３を示す光制御部材を有する照明器具の平面図と断面図、図８は光制御部材の平面図と側面図、図９は照明器具の光制御部材の取付構造の要部斜視図、図１０は図７の断面図の拡大図、図１１は動作説明図である。
【００２８】
図８において、実施の形態１の図１〜３及び実施の形態２の図６と同じ部分または相当部分には同一の符号を付し説明を省略する。９ｂはエンドプレート１ａ側に設けられた線バネ係止金具である。図９において７５ｂは線バネ係止金具９ｂの挿入部９０ａが挿入される長孔、（７５ｄ）はエンドプレート１ｂに長孔７５ｂと対向した位置に設けられ、線バネ係止金具９ｄの挿入部９０ａが挿入される長孔である。
【００２９】
なお、図１０に示すように、係止金具８ａは、Ｖ字形枠部７ａの外側側面部の上端縁部ｂとＶ字形枠部７ａの外側側面部と対向する反射板２の下端縁部ａとを結ぶ線ｃから下方の範囲に位置するように、Ｖ字形枠部７ａの内側側部に取り付けて、照明器具本体１の下方から取付金具８ａが見えないように構成されている。他の、係止金具８ｃ、線バネ係止金具９ｂ、９ｄ及びＶ字形枠部７ｂについても同じである。
【００３０】
次に、図７〜１１により動作を説明する。光制御部材５を器具本体１に装着するときは、光制御部材５の一方の線ばね係止金具９ｂの挿入部９０ａが突き出たまま、挿入部９０ａの先端をエンドプレート１ａの係止孔７５ｂに挿入し、光制御部材５の他方の線バネ係止金具９ｄの操作部９０ｂをたわませて挿入部９０ａを光制御部材５の内部に没入させ、挿入部９０ａがエンドプレート１ｂの係止孔７５ｄの位置に合うように光制御部材５を移動し、位置が合ったときに、操作部９０ｂを解放して挿入部９０ａを係止孔７５ｄに挿入させる。このとき、挿入されている線バネ係止金具９ｂ、９ｄを中心にして、光制御部材５が吊り下がった状態となる（図１１（ｃ））。
なお、線バネ係止金具９ｂ、９ｄを別々に係止孔７５ｂ、７５ｄに挿入したが、同時に挿入してもよい。
【００３１】
次に、光制御部材５の係止金具８ａ、８ｃの各々の操作部８０ｂをスライドさせ挿入部８０ａを光制御部材５の内部に没入させ、既に挿入された係止金具９ｂ、９ｄを中心にして、光制御部材５を回動させ、光制御部材５の係止金具８ｂの挿入部８０ｂがエンドプレート１ａの係止孔１３ａ、係止金具８ｃの挿入部８０ａがエンドプレート１ｂの係止孔１３ｃの位置に各々合ったとき、各々の操作部８０ｂを解放して挿入部８０ａを各々係止孔１３ａ、１３ｃに挿入させる（図１１（ａ））。
【００３２】
次に、光制御部材５を取り外すときは、光制御部材５の係止金具８ａ、８ｃの各々の操作部８０ｂをスライドさせ挿入部８０ａを光制御部材５の内部に没入させ、光制御部材５の係止金具８ａ、８ｃの挿入部８０ａを各々係止孔１３ａ、１３ｃから外すと、挿入されている線バネ係止金具９ｂ、９ｄを中心にして、光制御部材５が下方に回動し（図１１（ｂ））、吊り下がった状態となる（図１１（ｃ））。このとき、線バネ係止金具９ｂ、９ｄは係止孔７５ｂ、７５ｄの反射板２から離れた側に当てるようにして回動させ、光制御部材５が反射板２に接触しないようにする。
蛍光ランプ４を交換するときは、この状態で行い、上記のようにして光制御部材５を器具本体１に装着する。
【００３３】
光制御部材５を取外すときは、さらに、光制御部材５の線バネ係止金具９ｂ、９ｄの各々の操作部９０ｂをたわませて挿入部９０ａを光制御部材５の内部に没入させ、光制御部材５の線バネ係止金具９ｂ、９ｄの挿入部９０ｂを各々係止孔７５ｂ、７５ｄから外す。このとき、線バネ係止金具９ｂ、９ｄを一方ずつ取外してもよい。
【００３４】
以上のように、光制御部材５が反射板２に接している側に、線バネ係止金具９ｂ、９ｄを用い、線バネ係止金具係９ｂ、９ｄの支持部１４ａ、１４ｂを光制御部材５のＶ字形枠部７ｂの下部に設け、係止孔７５ｂ、７５ｄをエンドプレート１ａ、１ｂの下部に設けたので、光制御部材５の着脱時に、光制御部材５の回動中心軸が光制御部材５の下部となり、光制御部材５の下部が反射板２に接触するのを防ぐことができる。
また、係止孔７５ｂ、７５ｄを長孔としたので、光制御部材５の着脱時に光制御部材５を反射板２から離すようにしながら光制御部材５を回動させることができるので作業をしやすくすることができる。
【００３５】
また、係止金具８ａ、８ｃ及び線バネ係止金具９ｂ、９ｄを見えないようにして外観をよくすることができ、また、このときの着脱操作を簡単にすることができる。
また、ソケット３が見えないので見た目をスッキリさせることができる。
また、光制御部材５の長手方向に係止金具８ａ、８ｃ及び線バネ係止金具９ｂ、９ｄを配設しないことで、光制御部材５の長手方向の枠部が大きくならず、光を有効に出す器具本体１の開口部面積を大きくすることができる。
【００３６】
なお、本実施の形態では反射板２に接してない側に係止金具８ａ、８ｃを用いたが、線バネ係止金具９ａ、９ｃを用いてもよい。
【００３７】
実施の形態４．
実施の形態３では、光制御部材と反射板の接触をより密接にし、光が漏れないようにしたものである。
図１２は照明器具の光制御部材の取付構造の要部斜視図である。図において、実施の形態３の図９と同じ部分または相当部分には同一の符号を付し説明を省略する。１９ａはテーパ部を有する挿入部８５ａ、操作部８０ｂ、支持部８０ｃから構成される係止金具、１６ａは係止金具１９ａの挿入部８５ａが挿入される係止孔である。（１６ｃ）はエンドプレート１ｂに設けられる係止孔を示し、（１９ｃ）は光制御部材５のエンドプレート１ｂ側に設けられ、挿入部８５ａ、操作部８０ｂ、支持部８０ｃから構成される係止金具を示す。
【００３８】
この構成において、動作は実施の形態３と同じであるが、光制御部材５を本体器具１に装着するとき、係止金具１９ａ、１９ｃを係止孔１６ａ、１６ｃに挿入すると挿入部８５ａのテーパ部が挿入するに従って、図１２に示すように、Ａ方向にルーバが移動しルーバと反射板が密接する。
【００３９】
以上のように、光制御部材５と反射板２の接触をより密接にすることができ、光が漏れないようにすることができる。
【００４０】
【発明の効果】
