Description

【０００１】
【発明の属する技術分野】
本発明は、器具本体を開閉可能に設置した照明装置に関する。
【０００２】
【従来の技術】
従来、鉄道車両などの車両に車内灯として用いられる照明装置は、車内の天井に設置される器具本体を備え、この器具本体にはランプやこのランプを点灯させる点灯装置などが配設されている。器具本体の表面側にグローブなどの制光体が配置される場合には、制光体の一側がヒンジによって器具本体に回動可能に支持され、制光体の他側が係止機構によって器具本体に閉じた状態で解除可能に係止される。照明装置を車両に設置する場合には、車両側からのケーブルと器具本体の点灯装置から引き出されたケーブルとを電気的に接続した後、器具本体を車両側に固定している。ランプ交換の際には、制光体を開放して器具本体内のランプを交換している（例えば、特許文献１参照）。
【０００３】
【特許文献１】
特開平１１−９６８２４号公報（第２頁ないし第３頁、図１）
【０００４】
【発明が解決しようとする課題】
ところで、車両の天井裏に各種の機器が配置されており、車内側から天井裏の機器を点検するようにしている。器具本体の裏側に機器が配置されている場合には、器具本体の裏側を開放して機器の点検作業をしなければならない。器具本体の裏側を開放するには、車両側に固定している器具本体を天井から取り外すとともに器具本体側と車両側とを電気的に接続するケーブルを外し、取り外した照明器具を作業の邪魔にならない別の場所などに運んで載置しなければならない。また、点検後には、別の場所などに載置しておいた照明器具を運び込み、器具本体側と車両側とのケーブルを接続し、器具本体を天井に配置して車両側に固定しなければならない。
【０００５】
したがって、車両に設置されている器具本体の裏側を開放するには、車両からの器具本体の着脱を伴うため、作業性が悪い問題がある。
【０００６】
本発明は、このような点に鑑みなされたもので、器具本体を取り外すことなく器具本体の裏側を開放でき、作業性を向上できる照明装置を提供することを目的とする。
【０００７】
【課題を解決するための手段】
請求項１記載の照明装置は、器具本体と；器具本体に対して開閉可能に配置される制光体と；器具本体を設置する被設置部に対して器具本体を開閉可能に支持する器具本体用ヒンジ部と；制光体を器具本体に対して開閉可能に支持する制光体用ヒンジ部と；を具備しているものである。
【０００８】
そして、この構成では、制光体用ヒンジ部により制光体を器具本体に対して開閉可能に支持することで、例えばランプ交換や清掃などのメンテナンスが可能となることに加え、器具本体用ヒンジ部により器具本体を設置する被設置部に対して器具本体を開閉可能に支持するため、器具本体を取り外すことなく器具本体の裏側を開放可能とし、作業性が向上する。
【０００９】
請求項２記載の照明装置は、請求項１記載の照明装置において、器具本体用ヒンジ部および制光体用ヒンジ部が一体に設けられ、器具本体の一側および制光体の一側をそれぞれ回動可能に支持するヒンジを備えているものである。
【００１０】
そして、この構成では、ヒンジに、器具本体の一側および制光体の一側をそれぞれ回動可能に支持する器具本体用ヒンジ部および制光体用ヒンジ部を一体に設けたため、部品点数が削減される。
【００１１】
請求項３記載の照明装置は、請求項１または２記載の照明装置において、制光体は、制光部、制光部を支持し一辺が制光体用ヒンジ部に取り付けられた枠部、および枠部の一辺に取り付けられた補強金具を有しているものである。
【００１２】
そして、この構成では、制光体の制光体用ヒンジ部に取り付けられた枠部の一辺に補強金具を取り付けたため、制光体の変形が防止され、制光体の開閉が安定する。
【００１３】
請求項４記載の照明装置は、請求項１ないし３いずれか一記載の照明装置において、器具本体の端部との間に間隙をあけて器具本体の内側にランプソケットを取り付け、器具本体の端部とランプソケットとの間の間隙に反射体を取り付けたものである。
【００１４】
そして、この構成では、例えば使用するランプの長さより器具本体が比較的長く、器具本体の端部と器具本体の内側に取り付けられるランプソケットとの間に比較的大きく間隙があく場合でも、それら器具本体の端部とランプソケットとの間の間隙に反射体を取り付けたため、反射体からの反射光によって照明装置の端部側が明るくなる。
【００１５】
【発明の実施の形態】
以下、本発明の一実施の形態を図面を参照して説明する。
【００１６】
図１ないし図６に第１の実施の形態を示し、図１は照明装置の断面図、図２は照明装置のヒンジの底面図、図３は照明装置の側面図、図４は照明装置の正面図、図５は照明装置の制光体を開いた状態の断面図、図６は照明装置の制光体および器具本体を開いた状態の断面図である。
【００１７】
図３および図４に示すように、照明装置１１は、例えば鉄道の車両１２の室内灯として用いられるものであり、車両１２の車内に臨む被設置部としての天井部１３にその天井部１３の両側位置つまり車両１２の両側の側壁部１４との間にそれぞれ設置されているとともに、車両１２の長手方向に連続して複数の照明装置１１が設置されている。
【００１８】
照明装置１１は、器具本体２１、この器具本体２１に対して開閉可能に配置される制光体２２、これら器具本体２１および制光体２２の一側を天井部１３に対してそれぞれ個別に回動可能に支持する複数のヒンジ２３を備えている。
【００１９】
そして、図１および図２に示すように、ヒンジ２３は、天井部１３に複数のボルトやねじなどによって取り付ける複数の取付孔２６が設けられた取付部２７を有し、この取付部２７の両側に複数の筒状の軸受部２８が曲げ形成されている。
【００２０】
取付部２７の一端に器具本体２１の一側を回動可能に支持する器具本体用ヒンジ部２９が一体的に設けられている。この器具本体用ヒンジ部２９は、器具本体２１に複数のボルトやねじなどによって取り付ける複数の取付孔３０が設けられた取付片３１を有し、この取付片３１の端部に筒状の軸受部３２が曲げ形成され、この軸受部３２が取付部２７の複数の軸受部２８間に配置されてこれら軸受部２８，３２を挿通するヒンジ軸３３によって回動可能に軸支されている。
【００２１】
取付部２７の他端に制光体２２の一側を回動可能に支持する制光体用ヒンジ部３４が一体的に設けられている。この制光体用ヒンジ部３４は、制光体２２に複数のボルトやねじなどによって取り付ける複数の取付孔３５が設けられた取付片３６を有し、この取付片３６の端部に筒状の軸受部３７が曲げ形成され、この軸受部３７が取付部２７の複数の軸受部２８間に配置されてこれら軸受部２８，３７を挿通するヒンジ軸３８によって回動可能に軸支されている。
【００２２】
また、図１、図３および図４に示すように、器具本体２１は、ランプとして長尺な直管形蛍光ランプＬを使用する器具であってこの直管形蛍光ランプＬの長手方向に対応して長尺に形成されており、長手方向に長尺の基部４１、この基部４１の長手方向と交差する両側から拡開するように折曲形成された両側の側板４２，４３、および長手方向の両端に取り付けられた端板４４を有し、前面に照射開口４５が形成されている。そして、器具本体２１は、断面略三角形状に形成され、照射開口４５が車内の中央側に向くようにして天井部１３のコーナーに配置されている。
【００２３】
器具本体２１の内側の両端には、直管形蛍光ランプＬの両端の口金を接続する一対のランプソケット４６が取り付けられている。器具本体２１の上側には、直管形蛍光ランプＬを点灯させる点灯装置４７が取り付けられており、この点灯装置４７から引き出された電源入力ケーブル４８と車両１２の天井部１３に配線されている電源供給ケーブル４９とが着脱可能にコネクタ接続されている。
【００２４】
器具本体２１の一側の側板４２の内面側にヒンジ２３の器具本体用ヒンジ部２９の取付片３１が取り付けられ、器具本体用ヒンジ部２９を介して器具本体２１が天井部１３に回動可能に支持されている。
【００２５】
器具本体２１の他側の側板４３からは天井部１３を覆うカバー体５０が延長されて形成されている。このカバー体５０は他側の側板４３から折曲形成されていて器具本体２１に一体形成されており、側板４３の裏面側からカバー体５０の裏面側にわたって変形を防止する補強部材５１が取り付けられている。カバー体５０の先端側には、器具本体２１およびカバー体５０を天井部１３に閉じた状態で例えばねじなどの係止具によって天井部１３の構造物に着脱可能に係止するための複数の係止部５２が形成されている。
【００２６】
器具本体２１の照射開口４５の周辺部には、器具本体２１に閉じられる制光体２２の周辺部が接触する例えばゴム製の弾性を有するパッキング５３が粘着剤などで貼り付けて配置されている。器具本体２１の一側の側板４２にはパッキング５３を貼り付けて取り付けるパッキング取付部５４が折曲形成され、他側の側板４３にはパッキング５３を貼り付けて取り付けるブラケット５５が取り付けられ、端板４４にはパッキング取付部５４と同様に図示しないパッキング取付部が折曲形成されている。一側のパッキング取付部５４には、制光体２２の制光体用ヒンジ部３４側のパッキング５３について、制光体２２の制光体用ヒンジ部３４と反対側への移動を規制するストッパ５６が一体に折曲して設けられている。
【００２７】
また、制光体２２は、器具本体２１の照射開口４５に対応した長方形板状で光透過性を有する乳白色に形成された制光部としてのグローブ６１を有し、このグローブ６１の周辺が長方形枠状の枠部６２の裏面側に配置されて保持されている。枠部６２の中央部にはグローブ６１より小形の窓孔６３が形成され、枠部６２の裏面側の周辺部には例えばゴム製の弾性を有するパッキング６４を介してグローブ６１の周辺部を枠部６２の裏面側に押し付けて保持するグローブ押え金具６５が取り付けられている。制光体２２の裏面側の周辺部に配置されたグローブ押え金具６５は、制光体２２を器具本体２１に閉じた際に、器具本体２１の周辺部に配置されたパッキング５３に接触する接触部として構成されている。
【００２８】
枠部６２の一辺である一側の裏面側にヒンジ２３の制光体用ヒンジ部３４の取付片３６が取り付けられ、制光体用ヒンジ部３４を介して制光体２２が天井部１３に回動可能に支持されている。
【００２９】
制光体用ヒンジ部３４の取付片３６が取り付けられた枠部６２の一辺の裏面側には、枠部６２の変形を防止するための補給金具６６が取り付けられている。この補強金具６６は、制光体用ヒンジ部３４の取付片３６の部分を除き枠部６２の一辺の略全面域にわたって取り付けられており、枠部６２の外縁側の一端には天井部１３などと干渉しないように９０°以上曲げられた曲げ部６７が形成され、枠部６２の内側の他端にはグローブ６１、パッキング６４およびグローブ押え金具６５などと干渉しないように略直角に曲げられた曲げ部６８が形成されている。
【００３０】
枠部６２の他側にはカバー体５０の下面側に回り込んで配置される縁部６９が形成され、この縁部６９に、制光体２２を器具本体２１に閉じた状態で例えばねじなどの係止具によって器具本体２１側に着脱可能に係止するための複数の係止部７０が形成されている。
【００３１】
そして、照明装置１１を車両１２に設置する場合には、各ヒンジ２３の取付部２７を車両１２の天井部１３に固定する。器具本体２１の裏面側に取り付けられている点灯装置４７から引き出された電源入力ケーブル４８と車両１２の天井部１３に配線されている電源供給ケーブル４９とをコネクタ接続する。この配線の際、器具本体２１が既に天井部１３に取り付けられているため、配線作業を容易にできる。
【００３２】
器具本体２１およびカバー体５０をヒンジ２３の器具本体用ヒンジ部２９を介して回動させながら車両１２の天井部１３に閉じ合わせ、カバー体５０の各係止部５２を通じて例えばねじなどの係止具で天井部１３の構造物に係止する。
【００３３】
制光体２２をヒンジ２３の制光体用ヒンジ部３４を介して回動させながら器具本体２１に閉じ合わせ、各係止部７０を通じて例えばねじなどの係止具で器具本体２１側に係止する。制光体２２を器具本体２１に閉じることにより、制光体２２の裏面側の周辺部つまりグローブ押え金具６５が器具本体２１の周辺部に配置されたパッキング５３に接触し、害虫などが器具本体２１内に進入するのを防止する。
【００３４】
また、ランプ交換や、器具本体２１および制光体２２の清掃などの際には、図５に示すように、制光体２２の各係止部７０を器具本体２１側に係止している例えばねじなどの係止具による係止を解除し、制光体２２をヒンジ２３の制光体用ヒンジ部３４を介して下方へ回動させて開放し、器具本体２１の照射開口４５を開放する。
【００３５】
そのため、器具本体２１内の直管形蛍光ランプＬの交換や、器具本体２１の内面および制光体２２のグローブ６１の裏面側の清掃ができる。
【００３６】
また、器具本体２１の裏面側すなわち車両１２の天井部１３に設置されている例えば空調機などの機器の保守点検などの際には、図６に示すように、上述のように制光体２２を開放した後、カバー体５０の各係止部５２を天井部１３側に係止している例えばねじなどの係止具による係止を解除し、器具本体２１およびカバー体５０をヒンジ２３の器具本体用ヒンジ部２９を介して下方へ回動させて開放し、車両１２の天井部１３を開放する。
【００３７】
そのため、器具本体２１の裏面側すなわち車両１２の天井部１３が開放されるため、車両１２の天井部１３に設置されている例えば空調機などの機器の保守点検ができる。このとき、器具本体２１と一緒にカバー体５０も開放され、天井部１３が大きく開放されるため、天井部１３の機器の保守点検をより容易にできる。このとき、器具本体２１は天井部１３から取り外すことがなく、ヒンジ２３によって設置状態が保たれ、かつ、点灯装置４７の電源入力ケーブル４８と車両１２の天井部１３に配線されている電源供給ケーブル４９とを外すことがなく、配線接続状態が保たれる。
【００３８】
また、保守点検後は、上述した設置時のように、まず、器具本体２１およびカバー体５０を回動させて閉じて天井部１３に係止し、次に、制光体２２を回動させて器具本体２１に係止する。
【００３９】
そして、照明装置１１によれば、制光体用ヒンジ部３４により制光体２２を器具本体２１に対して開閉可能としたことで、例えばランプ交換や清掃などのメンテナンスができることに加え、器具本体用ヒンジ部２９により器具本体２１を設置する車両１２の天井部１３に対して車内側に器具本体２１を開閉可能としたため、器具本体２１を取り外すことなく、かつ、点灯装置４７の電源入力ケーブル４８と車両１２の天井部１３に配線されている電源供給ケーブル４９との配線接続を外すことなく、器具本体２１の裏側を開放でき、作業性を向上できる。
【００４０】
しかも、ヒンジ２３に、器具本体２１の一側および制光体２２の一側をそれぞれ回動可能に支持する器具本体用ヒンジ部２９および制光体用ヒンジ部３４を一体に設けたため、部品点数を削減できる。
【００４１】
また、制光体２２の制光体用ヒンジ部３４に取り付けられた枠部６２の一辺に補強金具６６を取り付けたため、制光体２２の変形を防止でき、制光体２２の開閉を安定させることができる。
【００４２】
また、制光体２２を器具本体２１に閉じる際、制光体２２を押し上げながら器具本体２１に閉じて係止するため、係止後に制光体２２がヒンジ２３の制光体用ヒンジ部３４と反対側すなわち下方へ移動し、このとき、制光体２２のグローブ押え金具６５が器具本体２１のパッキング５３に接触しているので、パッキング５３がこのパッキング５３を器具本体２１側に貼り付けている面と平行な斜め下方へ押圧される。あるいは、制光体２２を器具本体２１から開放する際、制光体２２のグローブ押え金具６５が器具本体２１のパッキング５３に圧着して貼り付いている場合には、パッキング５３がこのパッキング５３を器具本体２１側に貼り付けている面と平行な斜め下方へ押圧される。特に、器具本体２１に閉じられる制光体２２が接触する器具本体２１のパッキング５３のうち、制光体２２の制光体用ヒンジ部３４側のパッキング５３の部分において、パッキング５３が斜め下方へ強く押圧され、パッキング５３がパッキング取付部５４から剥離し易くなる。ただし、パッキング取付部５４にはストッパ５６を設けられているため、このストッパ５６によりパッキング５３が斜め方へ押圧されて移動するのを規制でき、制光体２２の開閉に伴うパッキング５３の剥離を防止できる。しかも、パッキング取付部５４にストッパ５６を一体に形成したため、別のストッパ部品を用いる必要がなく、部品点数を削減できる。
【００４３】
次に、図７に第２の実施の形態を示し、図７は照明装置の器具本体の端部の斜視図である。
【００４４】
通常の照明装置１１では、器具本体２１の長手方向の長さが直管形蛍光ランプＬの長手方向の長さに近く、器具本体２１内の直管形蛍光ランプＬを配置した状態での器具本体２１の端部と直管形蛍光ランプＬの端部との間の間隙が比較的小さく、照明装置１１の端部側でも明るい。車両１２の長手方向に連続して複数の照明装置１１を設置する場合に、車両１２の長手方向の長さ寸法と連続して設置する複数の照明装置１１の長さ寸法とが一致しないことが多く、照明装置１１の連続性を維持するために、通常の照明装置１１より長い照明装置１１ａが１つあるいは複数用いられて組み合わされる。この照明装置１１ａの場合、長さが長い器具本体２１の一端側に直管形蛍光ランプＬの一端側を寄せて配置した場合、器具本体２１の他端と直管形蛍光ランプＬの他端との間の間隙が大きいため、照明装置１１の他端部が暗くなる。
【００４５】
そこで、この照明装置１１ａにおいて、器具本体２１の端部と直管形蛍光ランプＬの端部との間に、直管形蛍光ランプＬの光を照明装置１１の端部側に反射させる反射体８１が取り付けられている。
【００４６】
反射体８１は、１枚の板材によって器具本体２１の断面形状に合わせて形成されており、ランプソケット４６が取り付けられた基部４１から器具本体２１の端部の照射開口４５にわたって斜めに配置される第１の反射面８２を有するとともに、器具本体２１の両側の側板４２，４３に沿って配置される第２の反射面８３を有している。反射体８１の表面は、器具本体２１の内面の光反射率より高い例えば鏡面に形成されている。
【００４７】
そして、この反射体８１により、直管形蛍光ランプＬの光を照明装置１１の端部側に反射させ、照明装置１１の端部側を明るくできる。
【００４８】
次に、図８に第３の実施の形態を示し、図８は照明装置の側面図である。
【００４９】
照明装置１１の端板４４における照射開口４５側の縁部９１の高さが低く、つまり端板４４における照射開口４５側の縁部９１に切欠部９２が形成され、端板４４の照射開口４５側で制光体２２との間に端部開口９３が形成されている。
【００５０】
そして、複数の照明装置１１を長手方向に連続して設置した場合に、隣接した照明装置１１間の端部間が端部開口９３を通じて互いに連通するため、隣接した照明装置１１の端部に各照明装置１１の直管形蛍光ランプＬの光が端部開口９３を通じて互いに侵入し、隣接した照明装置１１の端部が明るくなり、連続して設置される照明装置１１の明るさを均一にできて連続性が得られる。
【００５１】
また、制光体２２の表面側には、枠部６２のうち、制光体用ヒンジ部３４側である一側の枠部６２ａおよび制光体用ヒンジ部３４側と反対側である他側の枠部６２ｂのみが配置され、これら枠部６２ａ，６２ｂと交差した両端に枠部は配置されない。これら枠部６２ａ，６２ｂは裏面側の両端部が枠繋ぎ金具９６によって一体的に連結され、これら枠部６２ａ，６２ｂおよび枠繋ぎ金具９６によって枠部６２が構成されている。枠繋ぎ金具９６は、端板４４の切欠部９２の外形状つまり端部開口９３の外形状に対応して端板４４の内側に配置されるように形成され、両端に各枠部６２ａ，６２ｂ側に取り付けられる取付片９７が形成されている。枠繋ぎ金具９６の各取付片９７は、各枠部６２ａ，６２ｂに取り付けられたグローブ押え金具６５の端部に取り付けられている。
【００５２】
そして、制光体２２の表面側には枠部６２ａ，６２ｂと交差した両端に枠部は配置されないため、複数の照明装置１１を連続して配置した場合に、複数の照明装置１１のグローブ６１が一連に連続しているように視認でき、外観を向上できる。また、枠繋ぎ金具９６を端板４４の切欠部９２の外形状つまり端部開口９３の外形状に対応して端板４４の内側に配置されるように形成したため、端部開口９３を遮ることなく端部開口９３の開口状態を維持でき、隣接した照明装置１１の端部に各照明装置１１の直管形蛍光ランプＬの光が端部開口９３を通じて互いに侵入するようにできる。また、枠繋ぎ金具９６を各枠部６２ａ，６２ｂに取り付けられたグローブ押え金具６５の端部に取り付けるため、別の取付金具などを用いることなく取り付けることができ、部品点数を削減でできる。
【００５３】
なお、前記実施の形態では、器具本体用ヒンジ部２９および制光体用ヒンジ部３４を、ヒンジ２３に一体に設けたが、それぞれ別々に設けてもよい。この場合、制光体２２は、制光体用ヒンジ部３４によって、天井部１３でなく、器具本体２１に開閉可能に取り付けてもよい。
【００５４】
また、制光体２２の制光部としては、グローブ６１に限らず、バッフルやルーバーなどの制光に関する構成を用いることができる。
【００５５】
また、照明装置１１を鉄道の車両１２に適用したが、鉄道以外の車両や、あるいは建築物などにも適用でき、同様の作用効果を奏する。
【００５６】
【発明の効果】
請求項１記載の照明装置によれば、制光体用ヒンジ部により制光体を器具本体に対して開閉可能に支持することで、例えばランプ交換や清掃などのメンテナンスができることに加え、器具本体用ヒンジ部により器具本体を設置する被設置部に対して器具本体を開閉可能に支持するため、器具本体を取り外すことなく器具本体の裏側を開放でき、作業性を向上できる。
【００５７】
請求項２記載の照明装置によれば、請求項１記載の照明装置の効果に加えて、ヒンジに、器具本体の一側および制光体の一側をそれぞれ回動可能に支持する器具本体用ヒンジ部および制光体用ヒンジ部を一体に設けたため、部品点数を削減できる。
【００５８】
請求項３記載の照明装置によれば、請求項１または２記載の照明装置の効果に加えて、制光体の制光体用ヒンジ部に取り付けられた枠部の一辺に補強金具を取り付けたため、制光体の変形を防止でき、制光体の開閉を安定させることができる。
【００５９】
請求項４記載の照明装置によれば、請求項１ないし３いずれか一記載の照明装置の効果に加えて、例えば使用するランプの長さより器具本体が比較的長く、器具本体の端部と器具本体の内側に取り付けられるランプソケットとの間に比較的大きく間隙があく場合でも、それら器具本体の端部とランプソケットとの間の間隙に反射体を取り付けたため、反射体からの反射光によって照明装置の端部側を明るくできる。
