【発明が解決しようとする課題】
上記のような従来の照明器具では、円形蛍光灯９の装着時に三本の支持具１４の全てを円形蛍光灯９に嵌合させるまでは円形蛍光灯９の姿勢が安定せず、円形蛍光灯９を落下させる恐れがある。また、照明器具８廻りのスペースが狭い場合には、ソケット１３を円形蛍光灯９の口金ピンに嵌合させる操作が容易でなく煩雑な手数が掛かるという問題点があった。
【０００７】
この発明は、かかる問題点を解消するためになされたものであり、簡易な操作によって円形蛍光灯を容易に着脱することができる照明器具を得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においては、台座に設けられた円形蛍光灯用のスタータ及び安定器と、一端が互いに枢着されると共に台座に枢着された二本の取付リンクと、一端が取付リンクの回動端にそれぞれ枢着されて他端は互いに枢着された二本の支持リンクと、これら支持リンク相互の枢着端に装着された取っ手と、それぞれの支持リンクにおける取付リンクの枢着端側の端部に設けられ、それぞれ円形蛍光灯の横断面形に対応した湾曲形状をなし、互いに外向きに開口する支持具と、この支持具の湾曲形における内面に設けられて円形蛍光灯の口金ピンに対応し、スタータ及び安定器に接続されたソケットとが設けられる。
【０００９】
また、この発明に係る照明器具においては、台座に対する台座と取付リンクの取付部が、回動自在に構成されて一直線状態に配置された支持リンクを水平線に対して傾斜させ、支持具に保持された円形蛍光灯の姿勢を適宜に設定できる枢着部によって構成される。
【００１０】
【発明の実施の形態】
実施の形態１．
図１〜図１０は、この発明の実施の形態の一例を示す図で、図１はエレベーターかごの天井箇所の縦断面図、図２は図１のＢ部拡大図、図３は図２の平面図、図４は図２における円形蛍光灯の装着時の第一状況を示す図、図５は図２における円形蛍光灯の装着時の第二状況を示す図、図６は図２における円形蛍光灯の装着時の第三状況を示す図、図７は図２における円形蛍光灯の離脱時の第一状況を示す図、図８は図２における円形蛍光灯の離脱時の第二状況を示す図、図９は図２における円形蛍光灯の離脱時の第三状況を示す図、図１０は図１のＣ部拡大図である。
【００１１】
図において、１はかごの壁板、２は壁板１の上端に縁部が締結された天井、３は上縁部が天井２下面に締結された吊り天井、４は吊り天井３下面に形成された光天井で、両側の縁部寄りに縁部照明板５、縁部照明板５の相互間に配置されて中間が上方に湾曲した中央照明板６が設けられている。
【００１２】
７は送風装置で、天井２の上に設けられて壁板１と吊り天井３側面の間から送風する。１５は照明器具で次に述べるように構成されている。すなわち、１６は円形蛍光灯９用のスタータ１１及び安定器１２が設けられた台座、１７は一端が互いに枢着されると共に台座１６に枢着された二本の取付リンク、１８は一端が取付リンク１７の回動端にそれぞれ枢着されて他端は互いに枢着された二本の支持リンク、１９は支持リンク１８相互の枢着端に装着された取っ手である。
【００１３】
２０はそれぞれの支持リンク１８における取付リンク１７の枢着端側の端部に設けられて反取っ手１９側に開口し円形蛍光灯９の横断面形に対応した湾曲形状をなす支持具、２１は支持片で、円弧状をなし支持具２０の湾曲内面に嵌合状態に配置されて円形蛍光灯９の横断面が嵌合され、支持具２０の湾曲内面に対し円形蛍光灯９の横断面における外周面に沿う方向に摺動自在に装備されている。
【００１４】
２２は支持片２１の湾曲内面に設けられて円形蛍光灯９の口金ピン２３に対応したソケットで、配線２４によってスタータ１１及び安定器１２に接続されている。２５は台座１６に対する台座１６と取付リンク１７の枢着部である。なお、台座１６と取付リンク１７の枢着部２５、また取付リンク１７、支持リンク１８のそれぞれの枢着部は、取付リンク１７等の自重等による所定値以下の荷重によっては回動せず所定姿勢に保持され、また所定値を超えた外力が作用することによって回動するように構成されている。
【００１５】
上記のように構成された照明器具において、取付リンク１７、支持リンク１８によって四節リンク機構が構成される。以下、まず円形蛍光灯９を照明器具１５に装着する操作を説明する。すなわち、円形蛍光灯９が装着されていない状況であって、両方の支持リンク１８が一直線に配置された図２に示す状態から取っ手１９を引き下げると、四節リンク機構が菱形となり支持具２０は互いに接近して図４に示す状態となる。
【００１６】
そして、図４に示すように円形蛍光灯９の口金ピン２３を対応した支持片２１のソケット２２に挿入すると共に、円形蛍光灯９の円環の一側をソケット２２が設けられた支持具２０に嵌合する。次いで、取っ手１９を押し上げると図５に示すように両側の支持具２０が互いに離れる。そして、この動作と共に円形蛍光灯９の円環の他側を持ち上げる。
【００１７】
そして、さらに取っ手１９を押し上げて図６に示す状態において、円形蛍光灯９の円環の他側を他方の支持具２０に嵌合し、両方の支持リンク１８が一直線に配置されることによって図２に示すように円形蛍光灯９が照明器具１５に装着される。以上説明した操作において、円形蛍光灯９の口金ピン２３をソケット２２に挿入すると共に、円形蛍光灯９の円環の一側を支持具２０に嵌合した図５に示す状態によって、円形蛍光灯９が確実に支持具２０に保持される。
【００１８】
したがって、円形蛍光灯９を照明器具１５に装着するときに簡易な操作によって円形蛍光灯９を安定状態で支持具２０に保持することができる。また、円形蛍光灯９の装着操作の初期に円形蛍光灯９の円環の一側を支持具２０に嵌合することによって、円形蛍光灯９が確実に支持具２０に保持される。このため、円形蛍光灯９を落下させる粗相の発生を未然に防ぐことができる。
【００１９】
次に、円形蛍光灯９を照明器具１５から離脱する操作を説明する。すなわち、図２に示す状態から取っ手１９を引き下げると支持リンク１８が一直線状態から図７に鎖線で示す状態を経て実線で示す状態となる。また、円形蛍光灯９の円環における反口金ピン２３側が支持具２０から外れて図７に示す状態となる。そして、図８に示すように支持具２０下端からの支持片２１下端の突出寸法がＣ１となる。
【００２０】
この状態から、円形蛍光灯９の自重によって円形蛍光灯９の円環における反口金ピン２３側が下方へ移動して図９に示す状態となることにより、前述の突出寸法Ｃ１が図９に示す突出寸法Ｃ２と増大する。このため、円形蛍光灯９の横断面における鉛直方向の重合範囲が増し、円形蛍光灯９が安定した状態に支持片２１に掛合する。これより、円形蛍光灯９を照明器具１５から離脱する操作時に円形蛍光灯９を取り落とす粗相の発生を未然に防止することができる。
【００２１】
以上説明したように、簡易な操作によって円形蛍光灯９を照明器具１５に着脱でき、またこの操作時に円形蛍光灯９を安定した状態で支持具２０に保持することができる。これによって、照明器具１５に対する円形蛍光灯９の着脱が容易にでき作業能率を向上することができる。
【００２２】
また、円形蛍光灯９の装着操作時に円形蛍光灯９の円環の一側を支持具２０に嵌合することによって、円形蛍光灯９が確実に支持具２０に掛合される。また、円形蛍光灯９を照明器具１５から離脱するときに円形蛍光灯９が下垂することにより、円形蛍光灯９の横断面における鉛直方向の重合範囲が増す。このため、照明器具１５に対する離脱操作時に円形蛍光灯９を取り落とす粗相の発生を未然に防止することができる。
【００２３】
また、台座１６に対する台座１６と取付リンク１７の枢着部２５を回動し、一直線状態に配置された両方の支持リンク１８を水平線に対して傾斜させて図１０に示すように配置する。これによって、円形蛍光灯９の装着姿勢を光天井を形成する中央照明板６等の状況に合わせて適宜に設定することができる。このため、光天井における光むらの発生を防ぐことができ良好な照明作用を得ることができる。
【００２４】
【発明の効果】
この発明は以上説明したように、台座に設けられた円形蛍光灯用のスタータ及び安定器と、一端が互いに枢着されると共に台座に枢着された二本の取付リンクと、一端が取付リンクの回動端にそれぞれ枢着されて他端は互いに枢着された二本の支持リンクと、これら支持リンク相互の枢着端に装着された取っ手と、それぞれの支持リンクにおける取付リンクの枢着端側の端部に設けられ、それぞれ円形蛍光灯の横断面形に対応した湾曲形状をなし、互いに外向きに開口する支持具と、この支持具の湾曲形における内面に設けられて円形蛍光灯の口金ピンに対応し、スタータ及び安定器に接続されたソケットとを設けたものである。
【００２５】
これによって、取っ手を上下移動させて支持リンク等を回動し、支持具を相互に進退させる簡易な操作によって円形蛍光灯を照明器具に着脱でき、またこの操作時に円形蛍光灯を安定した状態で支持具に掛合することができる。このため、円形蛍光灯を照明器具に容易に着脱でき着脱作業を能率化する効果があり、また照明器具に対する着脱操作時に円形蛍光灯を落下させる粗相の発生を未然に防止する効果がある。
【００２６】
また、この発明は以上説明したように、台座に対する台座と取付リンクの取付部が、回動自在に構成されて一直線状態に配置された両方の支持リンクを水平線に対して傾斜させ、支持具に保持された円形蛍光灯の姿勢を適宜に設定できる枢着部によって構成したものである。
【００２７】
これによって、取っ手を上下移動させて支持リンク等を回動し、支持具を相互に進退させる簡易な操作によって円形蛍光灯を照明器具に着脱でき、またこの操作時に円形蛍光灯を安定した状態で支持具に掛合することができる。このため、円形蛍光灯を照明器具に容易に着脱でき着脱作業を能率化する効果があり、また照明器具に対する着脱操作時に円形蛍光灯を取り落とす粗相の発生を未然に防止する効果がある。さらに、円形蛍光灯の装着姿勢を光天井を形成する照明板の状況に合わせて適宜に設定することができ、光天井における光むらの発生を防ぐことができ良好な照明作用を得る効果がある。

The pivoting portions 25 of the pedestal 16 and the mounting link 17 and the pivoting portions of the mounting link 17 and the support link 18 are not rotated by a load below a predetermined value due to the weight of the mounting link 17 and the like. It is configured to rotate in response to an external force that is held in a posture and exceeds a predetermined value.
[0015]
In the lighting fixture configured as described above, the attachment link 17 and the support link 18 constitute a four-bar linkage mechanism. Hereinafter, the operation of mounting the circular fluorescent lamp 9 on the lighting fixture 15 will be described first. That is, when the circular fluorescent lamp 9 is not mounted and the handle 19 is pulled down from the state shown in FIG. 2 in which both the support links 18 are arranged in a straight line, the four-bar link mechanism becomes a rhombus and the support 20 is It will approach mutually and will be in the state shown in FIG.

Further, when the circular fluorescent lamp 9 is detached from the lighting fixture 15, the circular fluorescent lamp 9 hangs down, so that a vertical overlapping range in the cross section of the circular fluorescent lamp 9 is increased. For this reason, generation | occurrence | production of the rough phase which drops off the circular fluorescent lamp 9 at the time of detachment | leave operation with respect to the lighting fixture 15 can be prevented beforehand.
[0023]
Further, the pedestal 16 with respect to the pedestal 16 and the pivoting portion 25 of the attachment link 17 are rotated, and both support links 18 arranged in a straight line are inclined with respect to the horizontal line as shown in FIG. Thereby, the mounting posture of the circular fluorescent lamp 9 can be appropriately set according to the situation of the central illumination plate 6 and the like forming the optical ceiling. For this reason, generation | occurrence | production of the light nonuniformity in an optical ceiling can be prevented, and a favorable illumination effect | action can be obtained.
