Description

【０００１】
【発明の属する利用分野】
本発明は照明器具に関する。
【０００２】
【従来の技術】
本発明に係る従来例の側面断面図を図１０に、使用状態図を図１１に示す。
【０００３】
この照明器具は、取付面（ここでは天井面）に器具本体（以下、本体と呼ぶ。）２４が取り付けられるようにされたものであって、本体２４の前面側である下面開口側には、その下面開口側を略覆うように本体カバー（以下、カバーと呼ぶ。）２１が装着されるように構成されている。また、本体２４及びカバー２１によって形成される閉空間内に、図示しないランプソケット等によって装着され、図示しない電子点灯回路によって出力制御される図示しないランプが設けられている。
【０００４】
カバー２１は、本体２４と対向させたときに、その周端近傍であって本体２４に設けたバネ受金具２６と対向する位置に内側へ向けて突出するバネ２３が設けられて構成されている。また、本体２４は、バネ受金具２６と、バネ受金具２６と略対称な位置であってバネ２５によって付勢されるフック２２とが設けられて構成されている。そして、そのバネ２５をバネ受金具２３に取り付け、カバー２１のバネ２３側を押し上げてからフック２２側を押し上げることにより、カバー２１の内周縁部をフック２２に係合させて、カバー２１は本体２４に取り付けられる。また、カバー２１を下方向に引き下げてバネ２３をバネ受金具２６から取り外すことにより、カバー２１を本体２４から取り外すことができる。
【０００５】
【発明が解決しようとする課題】
しかし、上記従来例に示す様な照明器具では、以下に示すような問題点が生じてしまう。
【０００６】
カバー２１を取り外す際に、バネ２３側を先に取り外してしまうと、フック２２によりカバー２１の重量を支えることになるので、フック２２にストレスがかかってしまう。また、上記従来例では、カバー２１の内周縁部をフック２２に係合させているだけであり、特別の部材で結合していないので、バネ２３側を先に取り外してしまうと、場合によってはカバー２１が落下してしまう。
【０００７】
以上のような問題点を解決する手段としては、カバー２１の重量を一定値以下に規制する手段や、フック２２側にカバー２１の仮吊り様部材を設けるなどの手段が考えられるが、器具の大型化、コストアップを招いてしまう。
【０００８】
本発明は上記全ての問題点に鑑みてなされたもので、その目的とするところは、小型化可能で、カバー取り外しの際の信頼性及び安全性を向上可能な照明器具を低コストで提供することである。
【０００９】
【課題を解決するための手段】
上記問題点を解決するために、請求項１記載の発明によれば、内側面に受け金具と受け具とを有する下面開口の器具本体と、略Ｕ字形状の先端部及び略直線状のボディ部を有し弾性を有する線ばねを略Ｖ字状に折り曲げて形成した保持金具を上面部の周縁近傍に設けるととともに受け具に対応する箇所の各々に取付具を設けたカバーと、前記器具本体及び前記カバーによって形成される閉空間内に配置されるランプとを備え、カバーを下方に引き降ろせば前記取付具と前記受け具との係止が解除できる機構を有する照明器具であって、
前記カバーは、前記保持金具の前記略Ｕ字形状部を前記受け金具に係止することによって、前記器具本体の下面開口部の少なくとも一部を開放するとともに、前記受け金具と保持金具との寸法関係は、前記保持金具の略Ｕ字形状部が受け金具に当接しないときは、器具本体とカバーとの間の隙間に指が入らないものであることを特徴とする。
【００１０】
【実施の形態】
本発明に係る実施の形態の分解斜視図を図１に、その要部側面図を図２乃至６に示す。
【００１１】
この照明器具は、所謂、天井埋め込みタイプの照明器具であって、天井に設けた開口に器具本体（以下、本体と呼ぶ。）４をはめ込んで本体４を天井裏に位置させるようにして取付けるものである。そして、このように天井裏に位置するようにして天井に設けた開口にはめ込んで取付けられた本体４の下面開口部には、透光性を有する化粧カバー（以下、カバーと呼ぶ。）１８が配設して取付けられ、本体４の天井への取付け部分の化粧仕上げをするようになっている。
【００１２】
また、本体４は下方が開口した筒状または箱状をしており、その前面側である下面開口側には、その前面側の少なくとも一部を略覆うように本体カバー１５が装着され、本体４及び本体カバー１５の前面側を略覆うように、カバー１８が装着されるように構成されている。また、本体４及び本体カバー１５によって形成される閉空間内に、成形絶縁板５等の電気的な絶縁物を介して本体４の前面に対して略水平方向に保持配置されたプリント基板（以下、基板と呼ぶ。）１０上に、実装配置された電子部品１１を含んでなる電子点灯回路１２と、本体カバー１５の前面側にランプソケット９及びランプ支持バネ１４によって装着され、電子点灯回路１２によって出力制御される環形蛍光ランプ（以下、ランプと呼ぶ。）１６とが設けられている。
【００１３】
本体４は、その一方の内側面に受け具２を２つ設け、その内側面と対向する内側面に受け金具６を２つ設けており、受け具２は弾性を有する受けバネ８と、受けバネ８を保護するように覆う受け具カバー７とから構成される。また、本体４の外側面に電源供給を受ける１つの端子台１と、本体４を天井裏に係止させる為の４つの取付バネ３とが設けられている。
【００１４】
本体カバー１５は、上面部の周縁近傍の受け金具６に対応する箇所の各々に、略Ｕ字形状の先端部及び略直線状のボディ部を有し弾性を有する線ばねを略Ｖ字状に折り曲げて形成した保持金具１７と、上面部の周縁近傍の受け具２に対応する箇所の各々に、先端が略矢型形状の取付具１９とが取付けてある。この取付具１９は、受けバネ８に向かって押し込めば係止でき、カバー１８を下方に引き降ろせば係止を解除できる構造を有する。保持金具１７は、両下端部の軸支部が本体カバー１５の上面に設けた軸受け部に軸支してあり、線ばねを略Ｖ字状に折り曲げることでボディ部が左右に対向するようになっている。
【００１５】
カバー１８を取付けるには、取付具１９を対向する受けバネ８に係止することにより受けバネ８の弾性で取付具１９を保持した時点でちょうどカバー１８が所定の取付け位置になるように設定し、また、保持金具１７を受け金具６に挿入し保持金具１７の先端側を受け金具６に通過させた状態で取付けられ、つまり、保持金具１７のボディ部が受け金具６に弾接することでカバー１８を取付け支持するようにしている。
【００１６】
カバー１８を本体４から外す場合には、図６に示すように、通常は取付具１９側からカバー１８を下方に向かって引き降ろし、その後、図７に示すように、保持金具１７にてカバー１８を受け金具６に仮係止させてから外すことを望む。
【００１７】
ここで、保持金具１７側からカバー１８を下方に向かって引き降ろした場合には、図４及び図５に示すように、保持金具１７の略Ｕ字形状部が受け金具６に引っ掛かかるので、カバー１８が保持金具１７を介して受け金具６に仮係止された状態になる。この状態から保持金具１７を外すには、図９に示すように、一度、カバー１８を上方に持ち上げ、保持金具１７の略Ｕ字形状部が受け金具６に当接しないようにしてから、保持金具１７を内側へ摘まんで外す必要があるが、このとき、図８に示すように、本体４とカバー１８との間の隙間Ｌが非常に狭く、指が入らないなどにより保持金具１７を非常に操作しにくくなるように、略Ｕ字形状部の長さＸを設定すると、図５に示すように、先ず、保持金具１７側からカバー１８を下方に向かって引き降ろしてからカバー１８を本体４から取り外すことは限りなく不可能である。
【００１８】
よって、上記長さＸを適当な寸法に設定することにより、先ず、図６に示すように、取付具１９側からカバー１８を下方に向かって引き降ろし、その後、図７に示すように、保持金具１７にてカバー１８を受け金具６に仮係止させてから外す構成を実現することができる。
【００１９】
