Description

【０００１】
【発明の属する技術分野】
この発明は、照明器具に関するものである。
【０００２】
【従来の技術】
第１の従来例（たとえば特開平6-251611号公報) は、器具本体の丸穴部に支承体を差込み、引掛シーリングの引掛金具に支承体のフランジ部を係止して引掛シーリングに器具本体を取付けるものであった。
第２の従来例（たとえば実開平6-58514 号公報) は、引掛シーリングに引っ掛ける引掛爪を有する引掛シーリングキャップに通電メス金具を設け、通電メス金具に接触する通電オス金具を有して引掛シーリングキャップに嵌着するシーリング受け部材を器具本体に取付けているものであった。
【０００３】
【発明が解決しようとする課題】
第１の従来例は、照明器具を天井に取付ける場合、支承体と器具本体とを持って移動しなければならず、高所で取付作業をするとき片手では両者を持ちにくく、また両方の手に持つと不安定で危険であった。また器具本体の丸穴部に支承体を差し込むための位置合わせ等の作業が必要で高所作業では危険であった。さらに器具本体と支承体が別部品のため、器具の清掃等による取外しおよび取付けにおいて紛失のおそれがあった。
【０００４】
第２の従来例は、シーリング受け部材が器具本体に取付けられているが、受電オス金具が組み込まれているために構造が複雑で形状が大きくなって器具が大型化した。
したがって、この発明の目的は、器具本体の着脱作業が安全かつ容易にでき、部品の紛失がなく、しかも小型化を図ることができる照明器具を提供することである。
【０００５】
【課題を解決するための手段】

前記器具本体は回転により着脱自在なグローブを有し、前記本体支持体は前記グローブの回転中心に対して偏心した位置で前記器具本体に設けられているものである。
【０００６】
請求項１記載の照明器具によれば、本体支持体を器具本体に取付けたため、天井取付時に器具本体をもって取付作業をすればよいので片手で作業ができ、器具本体の着脱作業が安全かつ容易になる。また片手取付けが可能になるため省施工となり、器具本体に本体支持体が固定されているため本体支持体が紛失するおそれがない。また取付基体に本体支持体を回転により取付けるため、本体支持体および取付基体がコンパクトにできるので器具本体を小型化することができる。
また本体支持部がグローブの回転中心にある場合と比較して、ランプ交換や保守のためグローブを回転し着脱する際に、グローブの回転により器具本体が回転しようとする回転力が軽減し、本体支持体に加わるグローブの回転力が軽減されるので、器具本体の回転抑止を行うために器具本体と器具本体が取付けられるたとえば天井との間に摩擦係数の大きなパッキン等の部材を必要とせず、低コスト化でき、また外観上の制約もなくなる。
【０００７】
請求項２記載の照明器具は、天井の引掛シーリングに引っ掛ける引掛爪を有しこの引掛爪に接続された給電装置を有し回転係合部を下面に有する取付基体と、前記回転係合部に回転により係止する回転係止部を設けた本体支持体を有し前記給電装置を接続する接続部を有する器具本体とを備え、

請求項２記載の照明器具によれば、本体支持体を器具本体に取付けたため、天井取付時に器具本体をもって取付作業をすればよいので片手で作業ができ、器具本体の着脱作業が安全かつ容易になる。また片手取付けが可能になるため省施工となり、器具本体に本体支持体が固定されているため本体支持体が紛失するおそれがない。また取付基体に本体支持体を回転により取付けるため、本体支持体および取付基体がコンパクトにできるので器具本体を小型化することができる。
器具本体は天井に固定したまま本体支持体を回転することで取付基体に固定でき、天井面を傷付けたりすることがなく、また器具本体を回転して本体支持体を取付基体に取付ける場合と比較して取付基体に過大な力が加わらず破損等のおそれがない。
また本体支持部がグローブの回転中心にある場合と比較して、ランプ交換や保守のためグローブを回転し着脱する際に、グローブの回転により器具本体が回転しようとする回転力が軽減し、本体支持体に加わるグローブの回転力が軽減されるので、器具本体の回転抑止を行うために器具本体と器具本体が取付けられるたとえば天井との間に摩擦係数の大きなパッキン等の部材を必要とせず、低コスト化でき、また外観上の制約もなくなる。
【０００８】
請求項３記載の照明器具は、天井の引掛シーリングに引っ掛ける引掛爪を有しこの引掛爪に接続された給電装置を有し回転係合部を下面に有する取付基体と、前記回転係合部に回転により係止する回転係止部を設けた本体支持体を有し前記給電装置を接続する接続部を有する器具本体とを備え、
前記本体支持体は前記器具本体に対して回転可能に取付けられるものであって、前記器具本体は楕円形の取付孔を有し、前記本体支持体は前記取付孔に嵌合可能であって前記取付孔の短軸よりも長い長軸をもった楕円柱形の嵌合部を有し、前記取付孔の短軸方向の縁部に摺動自在に係合する係合溝を前記本体支持体の長軸方向の周面の周方向に形成したものである。
【０００９】
請求項３記載の照明器具によれば、本体支持体を器具本体に取付けたため、天井取付時に器具本体をもって取付作業をすればよいので片手で作業ができ、器具本体の着脱作業が安全かつ容易になる。また片手取付けが可能になるため省施工となり、器具本体に本体支持体が固定されているため本体支持体が紛失するおそれがない。また取付基体に本体支持体を回転により取付けるため、本体支持体および取付基体がコンパクトにできるので器具本体を小型化することができる。
器具本体は天井に固定したまま本体支持体を回転することで取付基体に固定でき、天井面を傷付けたりすることがなく、また器具本体を回転して本体支持体を取付基体に取付ける場合と比較して取付基体に過大な力が加わらず破損等のおそれがない。
また取付孔が楕円形であり本体支持体が楕円柱形の嵌合部を有するので本体支持体は９０度以上の範囲で取付孔に係合したまま本体支持体を回転することができる。このため、角形の照明器具を室内に取付けた場合、照明器具の角と部屋の角とがほぼ合致するように天井に照明器具取付け後器具本体をさらに回転させて調整することができ、角形の照明器具の位置合わせができる。また本体支持体を回転させて器具本体に固定できるので組立が容易であり、本体支持体の嵌合部が楕円形であるので回転操作時に手が滑りにくく操作しやすく、しかも固定部品が不要で組立も容易である。
【００１０】
請求項４記載の照明器具は、天井の引掛シーリングに引っ掛ける引掛爪を有しこの引掛爪に接続された給電装置を有し回転係合部を下面に有する取付基体と、前記回転係合部に回転により係止する回転係止部を設けた本体支持体を有し前記給電装置を接続する接続部を有する器具本体とを備え、

請求項４記載の照明器具によれば、本体支持体を器具本体に取付けたため、天井取付時に器具本体をもって取付作業をすればよいので片手で作業ができ、器具本体の着脱作業が安全かつ容易になる。また片手取付けが可能になるため省施工となり、器具本体に本体支持体が固定されているため本体支持体が紛失するおそれがない。また取付基体に本体支持体を回転により取付けるため、本体支持体および取付基体がコンパクトにできるので器具本体を小型化することができる。
また本体支持体は取付孔に係合したまま本体支持体を回転することができる。このため、角形の照明器具を室内に取付けた場合、照明器具の角と部屋の角とがほぼ合致するように天井に照明器具取付け後器具本体をさらに回転させて調整することができ、角形の照明器具の位置合わせができる。また本体支持体を回転させて器具本体に固定できるので組立が容易であり、本体支持体の嵌合部が角形であるので回転操作時に手が滑りにくく操作しやすく、しかも固定部品が不要で組立も容易である。
【００１１】
請求項５記載の照明器具は、請求項３または請求項４において、前記器具本体が回転により着脱自在なグローブを有し、前記本体支持体は前記グローブの回転中心に対して偏心した位置で前記器具本体に設けられているものである。
請求項５記載の照明器具によれば、請求項３または請求項４の効果のほか、本体支持部がグローブの回転中心にある場合と比較して、ランプ交換や保守のためグローブを回転し着脱する際に、グローブの回転により器具本体が回転しようとする回転力が軽減し、本体支持体に加わるグローブの回転力が軽減されるので、器具本体の回転抑止を行うために器具本体と器具本体が取付けられるたとえば天井との間に摩擦係数の大きなパッキン等の部材を必要とせず、低コスト化でき、また外観上の制約もなくなる。
【００１２】
請求項６記載の照明器具は、請求項１において、前記回転係合部が筒状をなし、前記回転係止部は前記回転係合部を嵌合する穴部を有し、前記給電装置はリード線とその先端に設けたコネクタを有し、前記リード線は前記回転係合部を通して引き出されて前記穴部に通されているものである。
請求項６記載の照明器具によれば、請求項１の効果のほか、比較的小さなコネクタおよびリード線を回転係合部から引出して穴部に通して、回転係合部と回転係止部のガイドを兼ねることにより、穴部が小さくても取付操作を容易に行えるとともに、穴部を小さくすることによって部品の小型化すなわち器具の小型化を実現することができる。
【００１３】
請求項７記載の照明器具は、請求項１において、前記本体支持体は前記取付基体の回転係合部に外嵌する略円筒状であり、前記取付基体の先端は前記本体支持体の内方に位置し、前記給電装置は前記取付基体の先端から前記本体支持体の外方に引き出したリード線と、このリード線の先端に接続したコネクタを有するものである。
【００１４】
請求項７記載の照明器具によれば、請求項１の効果のほか、本体支持体からのリード線の出代を少なくできるため、リード線がグローブ等に影として現れにくくなり器具を薄型化できる。
請求項８記載の照明器具は、天井の引掛シーリングに引っ掛ける引掛爪を有しこの引掛爪に接続された給電装置を有し回転係合部を下面に有する取付基体と、前記回転係合部に回転により係止する回転係止部を設けた本体支持体を有し前記給電装置を接続する接続部を有する器具本体とを備え、

【００１５】

本体支持体の回転係止部を取付基体の回転係合部に軸方向に差込むことにより結合することができるので、取付操作時間が短縮し、取付け操作性が向上する。
請求項９記載の照明器具は、天井の引掛シーリングに引っ掛ける引掛爪を有しこの引掛爪に接続された給電装置を有し回転係合部を下面に有する取付基体と、前記回転係合部に回転により係止する回転係止部を設けた本体支持体を有し前記給電装置を接続する接続部を有する器具本体とを備え、

【００１６】
請求項９記載の照明器具によれば、本体支持体を器具本体に取付けたため、天井取付時に器具本体をもって取付作業をすればよいので片手で作業ができ、器具本体の着脱作業が安全かつ容易になる。また片手取付けが可能になるため省施工となり、器具本体に本体支持体が固定されているため本体支持体が紛失するおそれがない。また取付基体に本体支持体を回転により取付けるため、本体支持体および取付基体がコンパクトにできるので器具本体を小型化することができる。
器具本体は天井に固定したまま本体支持体を回転することで取付基体に固定でき、天井面を傷付けたりすることがなく、また器具本体を回転して本体支持体を取付基体に取付ける場合と比較して取付基体に過大な力が加わらず破損等のおそれがない。
本体支持体の回転係止部を取付基体の回転係合部に軸方向に差込みかつ回転することにより結合することができるので、取付操作時間が短縮し、取付け操作性が向上する。
【００１７】
【発明の実施の形態】
この発明の第１の実施の形態を図１ないし図３により説明する。すなわち、この照明器具は、器具本体１と、取付基体１２とを有する。
取付基体１２は、天井１５の引掛シーリング（シーリングローゼット）４２に引っ掛ける引掛爪２４を有し、この引掛爪２４に接続された給電装置４１を有し、回転係合部２２を下面に有する。引掛シーリング２０の引掛孔４０は下面に形成され、引掛爪２４はこの引掛孔４０に電気的かつ機械的に係止する。実施の形態において、取付基体１２は引掛爪２４を引掛孔４０に差込み回転する際に把持しやすくなるように長方体形に形成されている。回転係合部２２は取付基体１２の下面より垂下した筒状の挿通部１２ａと、その先端の両側面に突設した係止突起２２ａにより形成している。給電装置４１は引掛爪２４に接続され挿通部１２ａを通して引き出されたリード線２５と、リード線２５の先端に接続されたコネクタ２６とを有する。
【００１８】
器具本体１は、回転係合部２２に回転して係止する回転係止部１９を設けた本体支持体２を有し、給電装置４１を接続する接続部２０を有する。実施の形態の器具本体１は上面に天井１５との間に介在されるスペーサ１６を設け、下面にランプソケット１７、ランプ支持ばね１８およびグローブ固定部４３を設け、グローブ２１の金具を用いたグローブ止め具４４をグローブ２１を水平回転することによりグローブ固定部４３に固定している。またランプソケット１７およびランプ支持ばね１８に環形蛍光ランプを用いたランプ２３が装着される。接続部２０に接続された点灯装置（図示せず）は内蔵されており、ランプソケット１７に給電している。
【００１９】
また実施の形態の本体支持体２は中空の略円筒形をなし、鍔部２ａをねじ４５により器具本体１に取付けている。また本体支持体２の回転係止部１９は本体支持体２の中空の穴部２ｂと、その内周面に図３に破線で示すように軸方向の縦溝と横溝部１９ａとで略Ｚ字形に形成された複数の溝１９′により形成しており、取付基体１２の挿通部１２ａに本体支持体２を外嵌し、回転係止部１９に回転係合部２２を摺動自在に挿通し、かつ回転して回転係止部１９の横溝部１９ａで係止している。
【００２０】
この照明器具の取付方法は、引掛シーリング４２に取付基体１２の引掛爪２４を引掛けて固定する。器具本体１に固定した本体支持体２の穴部２ｂにコネクタ２６のリード線２５を通し、挿通部１２ａの回転係合部２２が回転係止部１９に摺動するように挿通部１２ａを本体支持体２に挿入し、回転係止部１９の横溝部１９ａに回転係合部２２が移動するように器具本体１の本体支持体２を回転し係止する。コネクタ２６を接続部２０に接続する。これにより器具本体１の天井取付けが完了するが、一方器具本体１を外すときは前記と逆の操作をする。
【００２１】
この実施の形態によれば、本体支持体２を器具本体１に取付けたため、天井取付時に器具本体１をもって取付作業をすればよいので片手で作業ができ、器具本体１の着脱作業が安全かつ容易になる。また片手取付けが可能になるため省施工となり、器具本体１に本体支持体２が固定されているため本体支持体２が紛失するおそれがない。また取付基体１２に本体支持体２を回転により取付けるため、本体支持体２および取付基体１２がコンパクトにできるので器具本体１を小型化することができる。
【００２２】
また、回転係合部２２が筒状をなし、回転係止部１９は回転係合部２２を嵌合する穴部２ｂを有し、給電装置４１はリード線２５とその先端に設けたコネクタ２６を有し、リード線２５は回転係合部２２を通して引き出されて穴部２ｂに通されているため、比較的小さなコネクタ２６およびリード線２５を回転係合部２２から引出して穴部２ｂに通して、回転係合部２２と回転係止部１９のガイドを兼ねることにより、穴部２ｂが小さくても取付操作を容易に行えるとともに、穴部２ｂを小さくすることによって部品の小型化すなわち器具の小型化を実現することができる。この点、従来例では器具本体に設けられたホルダの貫通孔が大きく、アダプタとの嵌合の際にアダプタに突出したガイドの有無は取付け作業性に大きな影響を与えるものではなかった。これに対して、この実施の形態のように簡易取付け方式の照明器具を小型化する際に電気的な接続とリード線２５を突出させることにより、器具の取付け操作性を向上させることができるのである。
【００２３】
この発明の第２の実施の形態を図４および図５に示す。すなわち、この照明器具は、第１の実施の形態において、本体支持体２を器具本体１に対して回転可能に取付けたものである。この第２の実施の形態では、器具本体１の取付孔３を略半長円形に形成し、長円をなす周縁を下方に切曲げて略Ｌ字形で略Ｕ字形の係合リブ４を形成し、その両端にねじ孔９を形成している。本体支持体２は上端部に係合リブ４の内縁に摺動自在に係合する周溝５を形成し、この周溝５を係合リブ４の開放部に合わせ横にスライドして係合している。金具で形成した板状の外れ防止具６の両端に孔７を形成し、孔７を通して固定ねじ８をねじ孔９に締付けて外れ防止具６を開放部に取付け、本体支持体２を抜止めする。外れ防止具６は周溝５に係合してもよいし本体支持体２の外周面に摺接してもよい。
【００２４】
この実施の形態によれば、本体支持体２は外れ防止具６により係合リブ４から外れ防止され、係合リブ４に支持されて回転可能となる。したがって、器具本体１は天井１５に固定したまま本体支持体２を回転することで取付基体１２に固定でき、天井面１５の表面を傷付けたりすることがなく、また器具本体１を回転して本体支持体２を取付基体１２に取付ける場合と比較して取付基体１２に過大な力が加わらず破損等のおそれがない。その他は第１の実施の形態と同様である。
【００２５】
この発明の第３の実施の形態を図６および図７に示す。すなわち、この照明器具は、第１の実施の形態において、器具本体１が楕円形の取付孔３を有し、本体支持体２は取付孔３に嵌合可能であって取付孔３の短軸よりも長い長軸をもった楕円柱形の嵌合部２ａを有し、取付孔３の短軸方向の縁部に摺動自在に係合する係合溝３０を本体支持体２の長軸方向の周面の周方向に形成している。実施の形態において、器具本体１の中心に凸部３２を形成し、凸部３２の中心に取付孔３を形成している。本体支持体２は全体を中空の楕円柱形に形成し、その上端部を嵌合部２ａとしている。なお本体支持体２の中空部分は第１の実施の形態と同様に断面円形であり、その内面に回転係止部１９が形成されている。
【００２６】
この実施の形態によれば、取付孔３が楕円形であり本体支持体２が楕円柱形の嵌合部２ａを有するので本体支持体２は９０度以上の範囲Ｌで取付孔３に係合したまま本体支持体２を回転することができる。このため、角形の照明器具を室内に取付けた場合、照明器具の角と部屋の角とがほぼ合致するように天井１５に照明器具取付け後器具本体１をさらに回転させて調整することができ、角形の照明器具の位置合わせができる。また本体支持体２を回転させて器具本体１に固定できるので組立が容易であり、本体支持体２が楕円形であるので回転操作時に手が滑りにくく操作しやすく、しかも固定部品が不要で組立も容易である。その他は第１の実施の形態と同様である。なお、楕円は長円を含み、楕円柱は長円柱を含む。
【００２７】
この発明の第４の実施の形態を図８および図９に示す。すなわち、この照明器具は、第１の実施の形態において、器具本体１は角形の取付孔３を有し、本体支持体２は取付孔３に嵌合可能な角柱形の嵌合部２ａを有し、取付孔３の辺部３ａに摺動自在に係合する係合溝３０を嵌合部２ａの角部の周方向に形成している。実施の形態では、取付孔３が三角形をなし、本体支持体２が三角柱形をなしてその上端部を嵌合部２ａとしている。また器具本体１の中心に凸部３２を形成し、凸部３２の中心に取付孔３を形成している。なお本体支持体２の中空部分は第１の実施の形態と同様に断面円形であり、その内面に回転係止部１９を形成している。
【００２８】
この実施の形態によれば、本体支持体２は取付孔３に係合したまま本体支持体２を回転することができる。とくに取付孔３を三角形にし、本体支持体２が三角柱形の嵌合部２ａを有しているため、本体支持体２の回動範囲Ｌ1 は９０度以上にすることができる。このため、角形の照明器具を室内に取付けた場合、照明器具の角と部屋の角とがほぼ合致するように天井１５に照明器具取付け後器具本体１をさらに回転させて調整することができ、角形の照明器具の位置合わせができる。また本体支持体２を回転させて器具本体１に固定できるので組立が容易であり、本体支持体２が角形であるので回転操作時に手が滑りにくく操作しやすく、しかも固定部品が不要で組立も容易である。
【００２９】
この発明の第５の実施の形態を図１０および図１２に示す。すなわち、この照明器具は、第１の実施の形態ないし第４の実施の形態において、器具本体１が回転により着脱自在なグローブ２１を有しており、本体支持体２は器具本体１の中心に一致するグローブ２１の回転中心Ｐ1 に対して偏心した位置Ｐ2 で器具本体１に設けられている。実施の形態では本体支持体２がランプソケット１７とランプ支持ばね１８との間でランプ支持ばね１８寄りに偏位して配置されている。本体支持体２は器具本体１に回転自在に取付けられており、具体的には第２の実施の形態ないし第４の実施の形態を適用しているが、第１の実施の形態のように固定的に取付けられてもよい。２９は点灯装置である。
【００３０】
この実施の形態によれば、本体支持部２がグローブ２１の回転中心にある場合と比較して、ランプ交換や保守のためグローブ２１を回転し着脱する際に、グローブ２１の回転により器具本体１が回転しようとする回転力が軽減し、本体支持体２に加わるグローブ２１の回転力が軽減されるので、器具本体１の回転抑止を行うために器具本体１と天井１５との間に摩擦係数の大きなパッキン等の部材をとくに必要とせず、低コスト化できまた外観上の制約もなくなる。
【００３１】
その他は、第１の実施の形態ないし第４の実施の形態と同様である。
この発明の第６の実施の形態を図１３および図１４に示す。すなわち、この照明器具は、第１の実施の形態において、本体支持体２は取付基体１２の回転係合部２２に外嵌する略円筒状であり、取付基体１２の先端は本体支持体２の内方に位置し、給電装置４１のリード線２５は取付基体１２の先端から穴部２ｂを通して本体支持体２の外方に引き出して、その先端にコネクタ２６を接続している。取付基体１２の先端から出たリード線２５は、本体支持体２の先端で略Ｕ字形に曲がってコネクタ２６が接続部２０に接続されている。この場合、図１４に示すようにリード線２５は許容しうる最小の曲率半径Ｒで曲がるとき、本体支持体２の内径の直径Ｄとし、取付基体１２と本体支持体２との高さ方向の差Ｈとしたとき、Ｄ／２＞Ｒ，Ｈ＞Ｒの関係を保つように取付基体１２および本体支持体２の寸法を設定している。
【００３２】
この実施の形態によれば、本体支持体２からのリード線２５の出代を少なくできるため、リード線２５がグローブ２１等に影として現れにくくなり器具を薄型化できる。この点、たとえば取付本体１２の挿通部１２ａの先端が本体支持体２の下面と同一または本体支持体２よりも突出しているとき、リード線２５が下方に垂れ易くなり、リード線２５の影がグローブ２１に写るのを避けるため、器具本体１の高さが大きくなり易かった。これに対してこの実施の形態の簡易施工方式であって電源接続をリード線２５を介したコネクタ２６により接続する照明器具において、リード線２５の出代を極力少なくして器具高さを低くすることができる。
【００３３】
その他は第１の実施の形態ないし第５の実施の形態と同様である。
この発明の第７の実施の形態を図１５ないし図１７に示す。すなわち、この照明器具は、第１の実施の形態において、回転係合部２２と回転係止部１９とをねじにより構成し、回転係止部１９のねじ山５０は回転係止部１９を回転係合部２２に軸方向に差し込む際に径方向に後退可能としている。実施の形態において、回転係合部２２は雄ねじであり、回転係止部１９は雌ねじのあるスピードナットとしている。本体支持体２の回転係止部１９は穴部２ｂと、穴部２ｂの内周面に径方向に形成した複数溝５２と、これらの溝５２に出没自在に収納されたねじ山５０と、ねじ山５０を穴部２ｂ内に突出するように付勢するばね５１とを有する。ねじ山の最大突出量はストッパ（図示せず）により規制されている。そして、ねじ山５０の先端は軸方向の一方に向いた傾斜面５０ａを有する。
【００３４】
回転係止部１９を回転係合部２２に軸方向に外挿して押し上げるとき、ねじ山５０の傾斜面５０ａが回転係合部２２の雄ねじのねじ山に当たり、傾斜面５０ａが摺動してばね５１を圧縮するようにねじ山５０が後退する。このため、回転係止部１９を回転係合部２２に回転することなく軸方向に挿入することができる。回転係止部１９を回転係合部２２から外す方向にはねじ山５０に傾斜面がないので係止したままとなるが、ねじ戻し方向に回転することにより外すことができる。また回転係止部１９を回転係合部２２に挿入後に締めつける方向に回転することにより、回転係止部１９を強固に固定できる。
【００３５】
この実施の形態によれば、本体支持体２の回転係止部１９を取付基体１２の回転係合部２２に軸方向に差込みかつ回転することにより結合することができるので、取付操作時間が短縮し、取付け操作性が向上する。
なお、この実施の形態では、本体支持体２が器具本体１と分離されているが、図１７の状態に器具本体１に取付けられていてもよい。また回転係合部２２を雌ねじにし、回転係止部１９を雄ねじに構成してもよく、さらに雄ねじおよび雌ねじの一方のねじ山が後退可能な構成であればよい。
【００３６】
その他は第１の実施の形態ないし第６の実施の形態と同様である。
この発明の第８の実施の形態を図１８および図１９に示す。すなわち、この照明器具は、第１の実施の形態において、回転係合部２２および回転係止部１９は凹凸嵌合する構成であり、凸側となる回転係合部２２の側面にピン状の係止突起２２ａを突出し、凹側となる回転係止部１９に略７字状の溝部１９′を形成して、回転係止部１９を回転係合部２２に差込み回転により係合するものである。この実施の形態では、回転係合部２２の構成は第１の実施の形態と同様に挿通部１２ａと係止突起２２ａにより構成され、回転係止部１９は図１９に示すように器具本体１の取付孔３に回転自在に係合した溝５７を外周面に有し、穴部２ｂの内周面に逆姿勢の状態に略７字状の溝部１９′を有し、先端につば５８を形成し、かつ外端面にリング状凹部６４を形成した筒状の内体５６と、この内体５６に被冠してつば５８に回転自在に係合する内周溝５９を形成した把持用の外体６０と、内体５６のリング状凹部６４に収納され、内体５６および外体６０の間に介在されて両端がそれぞれ内体５６および外体６０にストッパ６２、６３により回動方向に移動するのを防止したねじりコイルばね６１とを有する。
【００３７】
器具本体１および外体６０を把持して、取付基体１２に対して押し上げ、挿通部１２ａに穴部２ｂを外挿すると、取付基体１２の係止突起２２ａと溝部１９′が嵌合する。さらに押し上げていくと、係止突起２２ａに規制された内体５６の溝部１９′に沿って内体５６のみがコイルばね６１のコイルばねのコイル中心を広げる方向に回転し始め、略７字状の溝部１９′の水平部までくると、コイルばね６１の復元力で内体５６は元の位置に戻り、係止突起２２ａが溝部１９′の端部に係止する。この間、人の操作は押し上げる操作だけで済み、回転操作が不要になる。
【００３８】
この実施の形態によれば、本体支持体２の回転係止部１９を取付基体１２の回転係合部２２に軸方向に差込みかつ回転することにより結合することができるので、取付操作時間が短縮し、取付け操作性が向上する。その他は第１の実施の形態ないし第７の実施の形態と同様である。
なお、回転係合部２２および回転係止部１９が凹凸嵌合する構成であり、凸側および凹側の一方の側面に係止突起２２ａを突出し、他方に略７字状の溝部１９′を形成して、回転係止部１９を回転係合部２２に差込み回転により係合するものであれば、前記と同作用効果がある。
