Description

【０００１】
【発明の属する技術分野】
本発明は、器具本体の基板に表側から安定器が取着される照明器具、詳しくはその安定器の取り付け構造に関するものである。
【０００２】
【従来の技術】
一般に、照明器具の安定器は器具本体内に納められている。しかしながら、照明器具が天井等に埋め込まれた状態に施工される埋め込み型である場合、安定器が器具本体内に納められていると、その点検や交換が困難となる。そこで、器具本体の基板の表側に安定器を取着して、この安定器を覆い隠すように反射板を取り付けた照明器具が提供されている。この場合、器具本体を天井等の施工個所から取り外すことなく反射板を取り外すだけで、安定器のメンテナンス作業を行うことができる。
【０００３】
そして、器具本体の基板の表側に安定器を取着する照明器具では、通常、図６に示す如く、安定器１の長手方向両端に取着部２を配設し、器具本体Ａの基板３に同安定器１の両取着部２各々が結合される固定部４を配設し、両固定部４に両取着部２を各々結合させて安定器１を基板３の表側に取着固定している。この場合は、取着部２及び固定部４がいずれも貫通孔で形成されており、両貫通孔となる取着部２と固定部４とに基板３の裏側から固定ボルト23を挿通して、この固定ボルト23に締付ナット24を螺合させることにより、両固定部４に両取着部２を各々ネジ止め固定している。
【０００４】
したがって、この照明器具にあっては、安定器１が器具本体Ａの基板３の表側に取着固定されているので、同安定器１のメンテナンス作業を表側から行うことができる。しかしながら、この場合、安定器１を交換するために基板３から取り外す際等に、締付ナット24を固定ボルト23から外すと、この固定ボルト23が同基板３の貫通孔となる固定部４から裏側へ抜け外れてしまうことがある。この場合には、安定器１を更めて取着する際に、固定ボルト23を基板３の裏側から貫通孔となる固定部４に挿入してセットし直す必要があり、器具本体Ａを天井等の施工個所から取り外さなければならなくなってしまう。
【０００５】
又、図７に示す如く、安定器１及び端子台13を給電部品台25に固定して、この給電部品台25を器具本体Ａの基板３の表側に取着固定してなる照明器具も知られている（特開２００２−１５６１７号公報参照）。この場合、給電部品台25に安定器１を固定ボルト23と締付ナット24とでネジ止め固定し、端子台13を同給電部品台25に係止固定し、その後に、この給電部品台25を基板３の表側に取着固定している。
【０００６】
その際、給電部品台25の長手方向両端には取着部２が配設され、基板３にはこの両取着部２各々が結合される固定部４が配設されており、両固定部４に両取着部２を各々結合させて同給電部品台25を基板３の表側に取着固定している。そして、一方の固定部4aを取着部2aがネジ止めされるものとなし、他方の固定部4bを取着部2bが引っ掛け係止されるものとなしている。この場合は、取着部2bを固定部4bに引っ掛け係止させた状態で、固定部4aに取着部2aがネジ止めされるものである。そして、ここでは、取着部2aと固定部4aとに基板３の裏側から固定ボルト23を挿通し、この固定ボルト23に蝶ナット26を螺合させ表側から締め付けることにより、同固定部4aに取着部2aをネジ止め固定している。
【０００７】
更には、この場合、基板３の貫通孔となる固定部4aにその裏側から挿通された固定ボルト23には、この固定ボルト23を同基板３に固定する締付ナット24が螺合されている。したがって、この照明器具にあっては、安定器１が給電部品台25と一体化されて器具本体Ａの基板３の表側に取着固定されているので、同安定器１のメンテナンス作業を表側から行うことができる。しかも、固定部4aに挿通される固定ボルト23は締付ナット24で基板３に固定されているので、同基板３から給電部品台25を取り外しても固定ボルト23が同固定部4aから裏側へ抜け外れることはない。しかしながら、この場合、安定器１を交換するために基板３から取り外す際、一体化された給電部品台25全体を同基板３から取り外す必要がある。

【発明が解決しようとする課題】
ところで、最近、この種の安定器は技術的な進歩により年々その小型化が図られており、又、安定器はその機能によって長手方向寸法が異なる場合も多い。そして、同じ寸法の安定器を交換する場合は、上記従来の技術に示した照明器具でも対応可能であるが、寸法の異なる安定器に交換する場合には、上記従来の技術に示したいずれの照明器具にあっても、その対応作業が困難となる。例えば、図６に示した照明器具では、器具本体Ａを天井等の施工個所から取り外し、同器具本体Ａの基板３に新たな固定部４として貫通孔を追加加工により形成しなければならず、このような作業を伴う交換は手間がかかって困難となる。又、図７に示した照明器具では、安定器１及び端子台13を一体化した給電部品台25全体を基板３から取り外し、この給電部品台25から更に同安定器１を取り外さなければならず、このような作業を伴う交換は手間がかかって困難となる。
【００１０】
本発明は、上記従来の技術における問題を悉く解決するために発明されたもので、その課題は、種類が異なってその長さ寸法の相違した安定器に交換する場合にも、簡単な作業で対応することができる照明器具を提供することである。
【００１１】
【課題を解決するための手段】
本発明の請求項１記載の照明器具は、安定器の長手方向両端に取着部を配設し、器具本体の基板には同安定器の両取着部各々が結合される固定部を配設し、両固定部に両取着部を各々結合させて安定器を基板の表側に取着固定してなる照明器具であって、基板における両固定部を結ぶ直線上で一方の固定部を、種類の異なる安定器の長さ相違寸法に対応した所定間隔で複数にして一連に配設してなるものである。
【００１２】
したがって、この場合、安定器が器具本体の基板の表側に取着固定されているので、同安定器のメンテナンス作業を表側から行うことができる。しかも、一方の固定部が基板における両固定部を結ぶ直線上で複数にして一連に配設され、同一方の各固定部は種類の異なる安定器の長さ相違寸法に対応した所定間隔で一連とされているので、種類が異なってその長さ寸法の相違した安定器に交換する場合にも、この交換で更めて取り付けられる安定器の長さ相違寸法に対応した一方の固定部を選択して、この固定部に同安定器の取着部を結合取着させることにより、簡単な作業で同交換に対応することができる。
【００１３】
又、本発明の請求項１記載の照明器具は、上記の照明器具において、一方の固定部を取着部がネジ止めされるものとなし、他方の固定部を取着部が引っ掛け係止されるものとなしたことを特徴としている。
【００１４】
したがって、この場合は特に、一方の固定部に取着部をネジ止め結合させる際に、他方の固定部に取着部を引っ掛け係止させて安定器を基板に対し仮保持させておくことができるので、同ネジ止め結合作業は容易となる。しかも、一方の固定部に取着部をネジ止め結合させた後には、この一方のネジ止めによる結合と他方の引っ掛け係止による結合とで、安定器が基板に対して安定した状態で取着保持され、又、同安定器を取り外す際には、一方だけでネジを弛める作業を行えばよく、安定器の交換作業がより手間を要しないものとなる。
【００１５】
本発明の請求項２記載の照明器具は、請求項１記載の照明器具において、ネジ止めされる方の固定部及びこの固定部に結合される取着部をいずれも貫通孔として形成し、両貫通孔となる取着部と固定部とに挿通される固定ネジによって、同取着部が固定部にネジ止めされるものとなしたことを特徴としている。
【００１６】
したがって、この場合は特に、両貫通孔となる取着部と固定部とに挿通される固定ネジによって、同取着部が固定部にネジ止めされるので、ネジ止めされる方の同固定部に対し取着部は位置合わせされて確実に結合固定される。
【００１７】
本発明の請求項３記載の照明器具は、上記請求項２記載の照明器具において、基板が金属板材料で形成されていて、ネジ止めされる方の固定部の貫通孔周縁にバーリング加工によって形成される筒状壁を基板の裏側へ突設し、取着部の貫通孔に表側から挿通される固定ネジをセルフタッピングネジで形成して、この固定ネジを前記筒状壁内にねじ込み挿通させることにより、同取着部が固定部にネジ止めされるものとなしたことを特徴としている。
【００１８】
したがって、この場合は特に、ネジ止めされる方の固定部がバーリング加工による筒状壁を有し、この筒状壁内に取着部の表側からセルフタッピングネジでなる固定ネジをねじ込み挿通させることにより、同取着部は固定部にネジ止めされるので、従来のように締付ナットを要さず、ネジ止め作業がより簡単となる。しかも、筒状壁は基板の裏側へ突設されていて邪魔にならず、従来のように、固定ボルト（或いは締付ナット）が同基板の裏側へ外れてしまうようなこともなくなり、これを同裏側からセットし直す必要もなくなって、安定器の交換作業は器具本体を天井等の施工個所から取り外すことなく簡単に行われる。
【００１９】
更に、本発明の請求項１記載の照明器具は、基板が金属板材料で形成されていて、引っ掛け係止される方の固定部を基板に切り起こし加工を施して同基板の表側へ突出形成し、ネジ止めされる方の固定部を、種類の異なる安定器の長さ相違寸法に対応した所定間隔で複数にして一連に配設したことを特徴としている。
【００２０】
したがって、この場合は特に、引っ掛け係止される方の固定部が基板に切り起こし加工を施して簡単に形成され、その際、この固定部は同基板の表側へ突出されるが、この表側に突出する固定部は一か所だけでよくて邪魔にならず、ネジ止めされる方の固定部を複数配設することにより、異なる長さ寸法の安定器の交換に支障なく対応することができるようになっている。
【００２１】
更に、又、本発明の請求項１記載の照明器具は、引っ掛け係止される方の固定部を略Ｌ字状に突出形成し、この固定部に結合される取着部を安定器の長手方向端の裏側から突出される板材料で形成し、この取着部の先端部分が同固定部に挿入されて引っ掛け係止されるものとなしたことを特徴としている。
【００２２】
したがって、この場合は特に、基板の表側へ略Ｌ字状に突出する固定部に、安定器の長手方向端の裏側から突出された板材料でなる取着部の先端部分が挿入されて引っ掛け係止されるので、この引っ掛け係止作業は同基板の表側からこれに沿わせて簡単且つ確実に行われる。
【００２３】
本発明の請求項４記載の照明器具は、上記請求項１〜３のいずれか一つに記載の照明器具において、引っ掛け係止する方の取着部を表側へ開口した略コ字型にして突出形成し、この取着部の両側壁間で当接規制されて略Ｌ字状の固定部が係合されるようになしたことを特徴としている。
【００２４】
したがって、この場合は特に、引っ掛け係止する方の取着部が表側へ開口した略コ字型にして突出形成され、略Ｌ字状の固定部は同取着部の両側壁間で当接規制されて係合されるので、この取着部を同固定部に対して横ズレなく位置決めされた状態で簡単且つ確実に引っ掛け係止させることができる。
【００２５】
本発明の請求項５記載の照明器具は、上記請求項４記載の照明器具において、引っ掛け係止される方の固定部を安定器の巾方向に切り起こし折曲させて形成し、この固定部を略コ字型に形成される取着部の両側壁各々に当接されるよう対にして配設し、両固定部を相互に内側へ傾斜させて突出形成すると共に、各固定部の取着部が摺接係止される略Ｌ字状内側縁をその先端側へと基板から離れるように傾斜させて形成したことを特徴としている。
【００２６】
したがって、この場合は特に、引っ掛け係止される方の固定部が略Ｌ字の板片状に形成されて略コ字型の取着部の両側壁に当接されるよう対に配設され、この両固定部は相互に内側へ傾斜され、各固定部の略Ｌ字状内側縁がその先端側へと基板から離れるように傾斜しているので、この両固定部に取着部を挿入して係止させている際に、各固定部の傾斜した略Ｌ字状内側縁は挿入される同取着部の先端部分に摺接係合し、これに伴って、両固定部は傾斜状態から直立状態へと変形されてこれによる復元力が同略Ｌ字状内側縁での係合部位に作用し、又、直立状態とされる両固定部は同取着部の両側壁に当接され易くなり、それ故、この取着部を同両固定部に対してガタツキなくより安定した状態で確実に引っ掛け係止させることができる。
【００２７】
【発明の実施の形態】
図１は、本発明の請求項１〜４に対応した第一の実施形態である照明器具を示す。この実施形態の照明器具は、安定器１の長手方向両端に取着部２を配設し、器具本体Ａの基板３には同安定器１の両取着部２各々が結合される固定部４を配設し、両固定部４に両取着部２を各々結合させて安定器１を基板３の表側に取着固定してなるものである。そして、この場合、基板３における両固定部４を結ぶ直線Ｌ上で一方の固定部４ａを、種類の異なる安定器１の長さ相違寸法に対応した所定間隔で複数にして一連に配設している。
【００２８】
又、この実施形態の照明器具では、一方の固定部4aを取着部2aがネジ止めされるものとなし、他方の固定部4bを取着部2bが引っ掛け係止されるものとなしている。そして、ネジ止めされる方の固定部4a及びこの固定部4aに結合される取着部2aをいずれも貫通孔として形成し、両貫通孔となる取着部2aと固定部4aとに挿通される固定ネジ５によって、同取着部2aが固定部4aにネジ止めされるものとなしている。この場合、基板３が金属板材料で形成されていて、ネジ止めされる方の固定部4aの貫通孔周縁にバーリング加工によって形成される筒状壁６を基板３の裏側へ突設し、取着部2aの貫通孔に表側から挿通される固定ネジ５をセルフタッピングネジで形成して、この固定ネジ５を前記筒状壁６内にねじ込み挿通させることにより、同取着部2aが固定部4aにネジ止めされるものとなしている。
【００２９】
又、この実施形態の照明器具では、基板３が金属板材料で形成されていて、引っ掛け係止される方の固定部4bを基板３に切り起こし加工を施して同基板３の表側へ突出形成し、ネジ止めされる方の固定部4aを、種類の異なる安定器１の長さ相違寸法に対応した所定間隔で複数にして一連に配設している。そして、引っ掛け係止される方の固定部4bを略Ｌ字状に突出形成し、この固定部4bに結合される取着部2bを安定器１の長手方向端の裏側から突出される板材料で形成し、この取着部2bの先端部分が同固定部4bに挿入されて引っ掛け係止されるものとなしている。この場合、引っ掛け係止する方の取着部2bを表側へ開口した略コ字型にして突出形成し、この取着部2bの両側壁７間で当接規制されて略Ｌ字状の固定部4bが係合されるようになしている。
【００３０】
以下、この実施形態の照明器具を、より具体的に説明する。安定器１は断面略コ字型の金属製型材21とその表側を覆うカバー部材22とを有し、同金属製型材21とカバー部材22とで囲まれるスペースに安定器１となるための回路部品や配線等が内蔵されている。安定器１の長手方向両端ではカバー部材22の端縁から金属製型材21の端部が突出し、この突出した金属製型材21の一方の端部にはその略コ字型の底板部分に貫通孔となるネジ止めする方の取着部2aが形成され、同他方の端部は略コ字型で引っ掛け係止する方の取着部2bとなる。この場合、引っ掛け係止する方の取着部2bにも貫通孔が形成されており、これは、上記図６で示した従来の照明器具における安定器１を用いたためで、同取着部2bの貫通孔が本発明では不要となる。
【００３１】
基板３は後記器具本体Ａの中程平坦部分を構成するもので、鋼板等の金属板材料で形成されている。基板３にはその長手方向一方側に貫通孔となる固定部4aが三つ配設され、同他方側には断面略Ｌ字状の固定部4bが一つだけ突出形成されている。この場合、貫通孔となる三つの固定部4aは、この固定部4aと他方の固定部4bの中央を結ぶ直線Ｌ上に略等間隔で配設されており、この間隔が種類の異なる安定器１の長さ相違寸法と対応している。又、各固定部4aの貫通孔周縁には、図１（ｂ）に示す如く、バーリング加工によって形成される略円筒形状の筒状壁６が基板３の裏側へ突設されている。そして、前記安定器１の貫通孔となる取着部2aに下方から挿通されるセルフタッピングネジで形成された固定ネジ５が、いずれか選択される一つの固定部4aの筒状壁６内にねじ込み挿入される。
【００３２】
他方、引っ掛け係止される方の断面略Ｌ字状の固定部4bは、基板３に切り起こし加工を施すことによりその表側に突出形成されるもので、この固定部4bの巾方向寸法が前記安定器１の略コ字型に突出する取着部2bの両側壁７間の間隔寸法と略合致されている。この場合、断面略Ｌ字状の固定部4bに前記安定器１の取着部2bが基板３の表面に沿いスライドされてスムーズに挿入係止され、挿入係止された状態で、同取着部2bはその両側壁７間で固定部4bが当接規制され、横ズレなく位置決めされて確実に引っ掛け係止される。そして、この取着部2bが固定部4bに引っ掛け係止された状態、すなわち、安定器１の一端を基板３に仮保持させた状態で、前記固定ネジ５は取着部2aに下方から挿通されて固定部4aの筒状壁６内にねじ込み挿入される。
【００３３】
ところで、この実施形態の照明器具は、例えば、図２に示す如き構造としてその全体が施工されるものである。この場合、天井Ｂに略矩形状の取付用開口９が形成され、器具本体Ａは同取付用開口内９に埋め込まれた状態に施工される。取付用開口９内には吊り下げ用の取付ボルト10が垂設されており、又、同取付用開口９からは外部配線である電源ケーブル11が導出され、この電源ケーブル11は器具本体Ａとなる基板３を貫通して端子台13に接続される。そして、端子台13から前記安定器１や後記ソケット12へと電源供給される。
【００３４】
器具本体Ａは下方へ開口した略矩形箱状であり、その長手方向で相対向する両側内面に対のソケット12が配設されており、同器具本体Ａの底板部分となる基板３の下面には前記安定器１が取着され、この安定器１と接続される端子台13も同基板３の下面に取着されている。そして、器具本体Ａは前記取付用開口９に下方から嵌め込まれて施工されるもので、その際、同器具本体Ａの基板３に形成された取付孔14に前記取付ボルト10が挿通され、この取付ボルト10には取付ナット15が螺合され、この取付ナット15をワッシャ16を介し同基板３の下面に対して締め付けることにより、器具本体Ａは天井Ｂ内に埋め込み施工されて吊り下げ固定される。
【００３５】
更に、ここでは、基板３の表側に安定器１及び端子台13を覆い隠すよう反射板17を取り外し得るようにして取着し、この反射板17よりも表側で照明ランプ18を器具本体Ａに接続保持させている。この場合、反射板17は断面略Ｖ字状に折曲した長板状に形成されており、基板３の中程部分にその長手方向に沿ってネジ止め等により取着固定されて、前記安定器１及び端子台13等の電気部品や取付ボルト10と取付ナット15との螺合部位を覆い隠すものである。そして、反射板17の両側各々では直管型の蛍光灯である照明ランプ18が、前記器具本体Ａに配設されたソケット12に接続保持されることによって装着される。
【００３６】
又、この実施形態の照明器具は、図３に示す如き構造としてその全体が施工されてもよい。この場合、器具本体Ａは矩形平板状の基板３で形成され、その両側に複数対の取着片19が突設されている。又、反射板17は下方へ開口した略矩形箱状に形成され、その底板部分の中程に断面略Ｖ字状に折曲された部分が形成されており、この断面略Ｖ字状に折曲した部分にて前記安定器１及び端子台13等の電気部品や取付ボルト10と取付ナット15との螺合部位が覆い隠されるもので、同反射板17は天井Ｂの取付用開口９に下方から嵌め込まれて器具本体Ａに取着固定されるものである。
【００３７】
その際、器具本体Ａとなる基板３の長手方向の両端部分各々で対にして垂設されるソケット12が反射板17を貫通してその下方に突設され、この状態で、同反射板17は前記器具本体Ａの各取着片19に対してツマミネジ20で取着固定される。そして、反射板17の下方に突設された各対のソケット12に、照明ランプ18が接続保持されることによって装着される。なお、それ以外の構造は、前記図２に示したものと同様であり、ここではその説明を省略する。
【００３８】
したがって、この実施形態の照明器具においては、安定器１が器具本体Ａの基板３の表側に取着固定されているため、同安定器１のメンテナンス作業を表側から反射板17を取り外すだけで簡単に行うことができる。しかも、一方の固定部4aが基板３における両固定部４を結ぶ直線Ｌ上で複数にして一連に配設され、同一方の各固定部4aは種類の異なる安定器１の長さ相違寸法に対応した所定間隔で一連とされているので、種類が異なってその長さ寸法の相違した安定器１に交換する場合にも、この交換で更めて取り付けられる安定器１の長さ相違寸法に対応した一方の固定部4aを選択して、この固定部4aに同安定器１の取着部2aを結合取着させることにより、簡単な作業で同交換に対応することができる。
【００３９】
又、この実施形態の照明器具においては、一方の固定部4aに取着部2aをネジ止め結合させる際に、他方の固定部4bに取着部2bを引っ掛け係止させて安定器１を基板３に対し仮保持させておくことができるので、同ネジ止め結合作業は一方だけで容易に行われる。しかも、一方の固定部4aに取着部2aをネジ止め結合させた後には、この一方のネジ止めによる結合と他方の引っ掛け係止による結合とにより、安定器１が基板３に対して安定した状態で取着保持される。又、安定器１を取り外す際には、一方だけでネジを弛める作業を行えばよく、同安定器１の交換作業がより手間を要しないものとなる。
【００４０】
又、この実施形態の照明器具においては、両貫通孔となる取着部2aと固定部4aとに挿通される固定ネジ５によって、同取着部2aが固定部4aにネジ止めされるので、ネジ止めされる方の同固定部4aに対し取着部2aは位置合わせされて確実に結合固定される。更に、この場合、ネジ止めされる方の固定部4aがバーリング加工による筒状壁６を有し、この筒状壁６内に取着部2aの表側からセルフタッピングネジでなる固定ネジ５をねじ込み挿通させることにより、同取着部2aは固定部4aにネジ止め固定されるので、従来のように締付ナット24を必要とせず、同ネジ止め作業がより簡単となる。
【００４１】
しかも、筒状壁６は基板３の裏側へ突設されていて邪魔にならず、従来のように、固定ボルト23（或いは締付ナット24）が同基板３の裏側へ外れてしまうようなこともなくなり、これを同裏側からセットし直す必要もなくなって、安定器１の交換作業は器具本体Ａを天井Ｂ等の施工個所から取り外すことなく簡単に行われる。すなわち、器具本体Ａから反射板17を取り外すだけで、天井Ｂ等に施工された状態のままの同器具本体Ａの基板３の表側から安定器１を容易に交換することができる。
【００４２】
又、この実施形態の照明器具においては、引っ掛け係止される方の固定部4bが金属板材料でなる基板３に切り起こし加工を施して簡単に形成され、その際、この固定部4bは同基板３の表側へ突出されるが、この表側に突出する固定部4bは同基板３において一か所だけでよく邪魔にならず、ネジ止めされる方の固定部4aを複数配設することにより、異なる長さ寸法の安定器１の交換に支障なく対応することができるようになっている。
【００４３】
又、この場合、基板３の表側へ略Ｌ字状に突出する固定部4bに、安定器１の長手方向端の裏側から突出された金属板材料でなる取着部2bの先端部分が挿入されて引っ掛け係止されるので、この引っ掛け係止作業は同基板３の表側からこれに沿わせて簡単且つ確実に行われる。しかも、その際、引っ掛け係止する方の取着部2bが表側へ開口した略コ字型にして突出形成されており、略Ｌ字状の固定部4bは同取着部2bの両側壁７間で当接規制されて係合されるので、この取着部2bを同固定部4bに対して横ズレなく位置決めされた状態で簡単且つ確実に引っ掛け係止させることができる。
【００４４】
図４、５は、本発明の請求項１〜５全てに対応した第二の実施形態である照明器具を示す。この実施形態の照明器具では、図５（ｂ）に示す如く、引っ掛け係止される方の固定部４ｂを安定器１の巾方向Ｘに外側へ切り起こし折曲させて形成し、図４にも示す如く、この固定部４ｂを略コ字型に形成される取着部２ｂの両側壁７各々に当接されるよう対にして配設し、両固定部４ｂを相互に内側へ傾斜（傾斜角度β）させて突出形成すると共に、図５（ａ）に示す如く、各固定部４ｂの取着部２ｂが挿入されて摺接係止される略Ｌ字状内側縁８を、その先端側へと基板３から離れるように傾斜（傾斜角度α）させて形成している。
【００４５】
この場合、両固定部4bは略Ｌ字状で基板３の長手方向に沿った板片として形成され、その基板３と対向する略Ｌ字状内側縁８が傾斜角度αで傾斜されて、この略Ｌ字状内側縁８と同基板３との間に形成される溝状部は奥方程その溝巾寸法が巾狭となるように形成されており、同溝状部の奥端における溝巾寸法はこれに挿入係止される取着部2bの板厚寸法と略等しいか少し小さく設定され、同溝状部の開口端における溝巾寸法は同取着部2bの板厚寸法よりも少し大きく設定されている。そのため、両固定部4bが基板３から傾斜角度βで傾斜するように突出されていると、前記溝状部に取着部2bが挿入されてその略Ｌ字状内側縁８が同取着部2bの先端部分に摺接係合されることにより、両固定片4bは直立突出状態に近くなるよう徐々に変形される。
【００４６】
したがって、この実施形態の照明器具においては、引っ掛け係止される方の固定部4bが略Ｌ字の板片状に形成されて略コ字型の取着部2bの両側壁７に当接されるよう対に配設され、この両固定部4bは相互に内側へ傾斜され、各固定部4bの略Ｌ字状内側縁８がその先端側へと基板３から離れるように傾斜しているので、この両固定部4bに取着部2bを挿入して係止させている際に、各固定部4bの傾斜した略Ｌ字状内側縁８は挿入される同取着部2bの先端部分に摺接係合し、これに伴って、両固定部4bは傾斜状態から直立状態へと変形されてこれによる復元力が同略Ｌ字状内側縁８での係合部位に作用し、又、直立状態とされる両固定部4bは同取着部2bの両側壁７に当接され易くなって、この取着部2bを同両固定部4bに対してガタツキなくより安定した状態で確実に引っ掛け係止させることができる。
【００４７】
なお、それ以外については、上記第一の実施形態と同様に構成されており、同第一の実施形態におけると同様の作用効果が奏されるので、ここではそれ等の説明を省略する。又、照明器具全体の施工構造としても、上記図２、３のいずれの全体施工構造であってもよいものである。
【００４８】
【発明の効果】
上述の如く、本発明の請求項１記載の照明器具においては、安定器のメンテナンス作業を表側から行うことができ、種類が異なってその長さ寸法の相違した安定器に交換する場合にも、この交換で更めて取り付けられる安定器の長さ相違寸法に対応した一方の固定部を選択して、この固定部に同安定器の取着部を結合取着させることにより、簡単な作業で同交換に対応することができる。

BACKGROUND OF THE INVENTION
The present invention relates to a lighting fixture in which a ballast is attached to the substrate of the fixture body from the front side, and more particularly to a mounting structure for the ballast.
[0002]
[Prior art]
Generally, the ballast of the lighting fixture is housed in the fixture body. However, in the case of the embedded type in which the lighting fixture is embedded in a ceiling or the like, if the ballast is stored in the fixture main body, it is difficult to check or replace the ballast. Therefore, a lighting fixture is provided in which a ballast is attached to the front side of the substrate of the fixture body, and a reflector is attached so as to cover the ballast. In this case, the maintenance work of the ballast can be performed only by removing the reflector without removing the instrument body from the construction site such as the ceiling.
[0003]
And in the lighting fixture which attaches a ballast to the front side of the board | substrate of a fixture main body, as shown in FIG. 6, the attachment part 2 is normally arrange | positioned at the longitudinal direction both ends of the stabilizer 1, and the board | substrate 3 of the fixture main body A is shown. Are provided with fixing parts 4 to which both mounting parts 2 of the ballast 1 are connected, and both fixing parts 4 are connected to both fixing parts 4 to attach the ballast 1 to the front side of the substrate 3. It is fixed. In this case, both the attachment part 2 and the fixing part 4 are formed by through holes, and the fixing bolts 23 are inserted into the attachment part 2 and the fixing part 4 serving as both through holes from the back side of the substrate 3. The fastening nuts 24 are screwed to the fixing bolts 23 to fix the both attaching portions 2 to the both fixing portions 4 with screws.
[0004]
Therefore, in this lighting apparatus, since the ballast 1 is attached and fixed to the front side of the substrate 3 of the main body A, the maintenance work of the ballast 1 can be performed from the front side. However, in this case, when the clamping nut 24 is removed from the fixing bolt 23 when removing the ballast 1 from the board 3 in order to replace the ballast 1, the fixing bolt 23 is removed from the fixing portion 4 that becomes a through hole of the board 3. It may come off to the back side. In this case, when the ballast 1 is further attached, it is necessary to insert the fixing bolt 23 from the back side of the substrate 3 into the fixing portion 4 serving as a through hole, and set it again. Will have to be removed from the construction site.
[0005]
In addition, as shown in FIG. 7, there is also known a lighting fixture in which the ballast 1 and the terminal block 13 are fixed to a power supply component base 25, and this power supply component base 25 is attached and fixed to the front side of the board 3 of the fixture body A. (See JP 2002-15617 A). In this case, the ballast 1 is fixed to the power supply component base 25 with a fixing bolt 23 and a tightening nut 24, and the terminal block 13 is locked and fixed to the power supply component base 25. Thereafter, the power supply component base 25 is fixed. Is fixed to the front side of the substrate 3.
[0006]
At that time, the attachment parts 2 are arranged at both ends in the longitudinal direction of the power supply component base 25, and the fixing parts 4 to which the both attachment parts 2 are coupled are arranged on the substrate 3. 4, both attachment portions 2 are coupled to each other, and the power supply component base 25 is attached and fixed to the front side of the substrate 3. One fixing portion 4a is attached to the attaching portion 2a, and the other fixing portion 4b is attached to the attaching portion 2b. In this case, the attachment portion 2a is screwed to the fixing portion 4a in a state where the attachment portion 2b is hooked and locked to the fixing portion 4b. In this case, the fixing bolt 23 is inserted into the attachment portion 2a and the fixing portion 4a from the back side of the substrate 3, and a wing nut 26 is screwed into the fixing bolt 23 and tightened from the front side to thereby fix the fixing portion 4a. The attachment portion 2a is fixed with screws.
[0007]
Further, in this case, a fixing nut 23 that fixes the fixing bolt 23 to the substrate 3 is screwed to the fixing bolt 23 inserted from the back side into the fixing portion 4a that becomes a through hole of the substrate 3. . Therefore, in this lighting fixture, since the ballast 1 is integrated with the power supply component base 25 and fixed to the front side of the board 3 of the fixture body A, the maintenance work for the ballast 1 is performed from the front side. It can be carried out. Moreover, since the fixing bolt 23 inserted into the fixing portion 4a is fixed to the substrate 3 with the tightening nut 24, the fixing bolt 23 is moved from the fixing portion 4a to the back side even if the power supply component base 25 is removed from the substrate 3. It will not come off. However, in this case, when the ballast 1 is removed from the substrate 3 in order to replace the ballast 1, it is necessary to remove the entire power supply component base 25 from the substrate 3.

And when exchanging a ballast of the same size, it is possible to deal with the lighting fixtures shown in the above-mentioned prior art. Even if it is in a lighting fixture, the corresponding work becomes difficult. For example, in the lighting apparatus shown in FIG. 6, the apparatus body A must be removed from a construction site such as a ceiling, and a through hole must be formed as a new fixing portion 4 in the substrate 3 of the apparatus body A by additional processing. Replacement involving such work is time consuming and difficult. Further, in the lighting apparatus shown in FIG. 7, the entire power supply component base 25 in which the ballast 1 and the terminal block 13 are integrated must be removed from the substrate 3, and the ballast 1 must be further removed from the power supply component base 25. The exchange involving such work is time consuming and difficult.

The fixed portion 4b is abutted and regulated between the side walls 7 of the portion 2b, and the portion 2b is positioned without lateral displacement and is securely hooked and locked. The fixing screw 5 is inserted into the mounting portion 2a from below in a state where the mounting portion 2b is hooked and locked to the fixing portion 4b, that is, in a state where one end of the ballast 1 is temporarily held on the substrate 3. Then, it is screwed and inserted into the cylindrical wall 6 of the fixed portion 4a.
[0033]
By the way, the whole lighting fixture of this embodiment is constructed as a structure as shown in FIG. 2, for example. In this case, a substantially rectangular mounting opening 9 is formed in the ceiling B, and the instrument body A is constructed in a state of being embedded in the mounting opening 9. A hanging mounting bolt 10 is suspended in the mounting opening 9, and a power cable 11, which is an external wiring, is led out from the mounting opening 9. Is connected to the terminal block 13 through the substrate 3. Then, power is supplied from the terminal block 13 to the ballast 1 and the socket 12 described later.
[0034]
The instrument body A has a substantially rectangular box shape that opens downward, and a pair of sockets 12 are disposed on the inner surfaces of both sides facing each other in the longitudinal direction. The ballast 1 is attached, and a terminal block 13 connected to the ballast 1 is also attached to the lower surface of the substrate 3. And the instrument main body A is inserted into the mounting opening 9 from below, and is constructed. At that time, the mounting bolt 10 is inserted into the mounting hole 14 formed in the substrate 3 of the instrument main body A, and this A mounting nut 15 is screwed onto the mounting bolt 10, and by tightening the mounting nut 15 against the lower surface of the substrate 3 via a washer 16, the instrument main body A is embedded in the ceiling B and suspended and fixed. The
[0035]
Further, here, the reflector 17 is attached to the front side of the substrate 3 so as to be able to cover the ballast 1 and the terminal block 13, and the illumination lamp 18 is attached to the instrument body A on the front side of the reflector 17. The connection is maintained. In this case, the reflecting plate 17 is formed in a long plate shape bent in a substantially V-shaped cross section, and is fixed to the middle portion of the substrate 3 by screwing or the like along the longitudinal direction thereof. It covers the electrical parts such as the container 1 and the terminal block 13 and the screwed portions of the mounting bolt 10 and the mounting nut 15. On both sides of the reflector plate 17, an illumination lamp 18, which is a straight tube type fluorescent lamp, is mounted by being connected and held to the socket 12 disposed in the instrument body A.
[0036]
Moreover, the whole lighting fixture of this embodiment may be constructed as a structure as shown in FIG. In this case, the instrument main body A is formed of a rectangular flat plate-shaped substrate 3, and a plurality of pairs of attachment pieces 19 are provided on both sides thereof. The reflecting plate 17 is formed in a substantially rectangular box shape that opens downward, and a portion bent in a substantially V-shaped cross section is formed in the middle of the bottom plate portion. The reflecting plate 17 is folded in a substantially V-shaped cross section. In the bent portion, the electrical parts such as the ballast 1 and the terminal block 13 and the screwed portion between the mounting bolt 10 and the mounting nut 15 are covered and the reflector 17 is provided in the mounting opening 9 of the ceiling B. It is fitted from below and fixed to the instrument body A.

At that time, sockets 12 suspended in pairs at both ends in the longitudinal direction of the substrate 3 serving as the instrument body A pass through the reflecting plate 17 and project downwardly. In this state, the reflecting plate 17 Is fixedly attached to each attachment piece 19 of the instrument body A with a knob screw 20. Then, the illumination lamp 18 is mounted and connected to each pair of sockets 12 protruding below the reflecting plate 17. The other structure is the same as that shown in FIG. 2, and the description thereof is omitted here.
[0038]
Therefore, in the lighting fixture of this embodiment, since the ballast 1 is attached and fixed to the front side of the substrate 3 of the fixture main body A, the maintenance work of the ballast 1 is simply performed by removing the reflector 17 from the front side. Can be done. In addition, one fixed portion 4a is arranged in series on the straight line L connecting the two fixed portions 4 in the substrate 3, and the same fixed portion 4a has different lengths of different types of ballasts 1. Since it is made into a series at the corresponding predetermined intervals, even when the ballast 1 is replaced with a ballast 1 of a different type and a different length size, the length difference size of the ballast 1 to be further attached by this replacement is changed. By selecting one of the corresponding fixed portions 4a and connecting and attaching the mounting portion 2a of the ballast 1 to the fixed portion 4a, it is possible to cope with the replacement by a simple operation.
[0039]
Further, in the lighting apparatus of this embodiment, when the attachment portion 2a is screwed and coupled to one fixing portion 4a, the attachment portion 2b is hooked and locked to the other fixing portion 4b to fix the ballast 1 to the substrate. 3 can be temporarily held, so that the screwing and joining operation can be easily performed by only one side. In addition, after the attachment portion 2a is screwed to one fixing portion 4a, the ballast 1 is stabilized with respect to the substrate 3 by this one screwing connection and the other hooking engagement. It is attached and held in the state. Further, when the ballast 1 is removed, it is only necessary to loosen the screw with one side, and the work for exchanging the ballast 1 becomes less time-consuming.
[0040]
Further, in the lighting fixture of this embodiment, since the attachment portion 2a is screwed to the fixing portion 4a by the fixing screw 5 inserted through the attachment portion 2a and the fixing portion 4a serving as both through holes, The mounting portion 2a is aligned and securely fixed to the fixing portion 4a to be screwed. Further, in this case, the fixing part 4a to be screwed has a cylindrical wall 6 by burring, and a fixing screw 5 made of a self-tapping screw is screwed into the cylindrical wall 6 from the front side of the attachment part 2a. By inserting, the attaching portion 2a is fixed to the fixing portion 4a with screws, so that the tightening nut 24 is not required as in the conventional case, and the screwing operation becomes easier.
[0041]
In addition, the cylindrical wall 6 protrudes from the back side of the substrate 3 and does not get in the way, and the fixing bolt 23 (or the tightening nut 24) may come off to the back side of the substrate 3 as in the prior art. This eliminates the need to reset the ballast 1 from the back side, and the ballast 1 can be easily replaced without removing the fixture body A from the construction site such as the ceiling B. That is, the ballast 1 can be easily replaced from the front side of the substrate 3 of the instrument main body A as it is applied to the ceiling B or the like by simply removing the reflector 17 from the instrument main body A.
[0042]
In the lighting fixture of this embodiment, the fixing portion 4b to be hooked and locked is simply formed by cutting and raising the substrate 3 made of a metal plate material. In this case, the fixing portion 4b is the same as the fixing portion 4b.
