Description

【０００１】
【発明の属する技術分野】
本発明は、ＡＣ１００Ｖコンセントがない場所であっても周囲を照明することができる照明装置に関するものである。
【０００２】
【従来の技術】
近年、乾電池や充電式電池、バッテリー等の電源手段を電源として周囲の照明を行うことができる照明装置が提供されている。これらの照明装置は夜に周囲が暗くなると自動点灯したり、人が近くに来た場合にのみ点灯させる等のセンサーライトと称されるものである。これらの照明装置はＡＣ１００Ｖコンセントが配置されていない廊下、通路、玄関、物置等に設置されるものであり、予め住宅に設置されている照明装置では照明を行うことができない所に設置されることが多い。
【０００３】
【発明が解決しようとする課題】
この種の電池式の照明装置はどこでも使用することができる利点がある。しかしながら、この種の電池式の照明装置は引っ掛け式又はねじ止めなどによる完全固定式により取付けられており、引っ掛け式では手等の体が触れる位置や、地震等の衝撃により照明器具本体が落下して怪我をするという問題があり、また、完全固定式では前記のような問題はないが、一度取付けると取り外しが困難又は取り外しに手間がかかるという問題がある。更に、上記引っ掛け式のものは取り外しことができると言えども、取り外して床や机や家具やその他の台等に載せて使用する場合には設置が不安定で、設定された姿勢での使用ができないという問題がある。
【０００４】
本発明は上記の従来例の問題点に鑑みて発明したものであって、取付け、取り外しが容易で、しかも、取り外した場合に床や机や家具やその他の台等の上に載せて安定して設定された姿勢で使用でき、また、壁や天井等の取付け面に取付けた固定部に取付けた状態では人、地震等による衝撃があっても簡単に外れないように着脱でき、更に固定部に被固定部を取付けた状態で、回動自在な照明器具を回動させた場合に壁や天井等の取付け面からの突出長さを短くできる照明装置を提供することを課題とするものである。
【０００５】
【課題を解決するための手段】
上記課題を解決するために、本発明の照明装置は、内部に電源手段１を収容した照明器具本体３と、照明器具本体３の背部から突出したアーム部１３と、アーム部１３と回動自在に軸支する軸受け部１４を前面側に設けた被固定部２と、壁や天井等に固定されるものであって被固定部２を着脱自在に取付ける固定部５とを備えた照明装置において、軸受け部１４又はアーム部１３のいずれかに押圧手段により押圧される軸用突部１６を設けると共にいずれか他方に軸用突部１６が回動自在に嵌まり込むはまり込み部１７を設けて軸用突部１６とはまり込み部１７とで回動部１５を構成し、照明器具本体３の前面に対して直交する方向で照明器具本体３の側面を２分割する分割線Ｍを設定し、照明器具本体３を回動して分割線Ｍが被固定部２の前面と略平行となった状態で該分割線Ｍと被固定部２の前面との間に上記回動部１５の回動中心が位置するように設定し、被固定部２を照明器具本体３の置き台４として成ることを特徴とするものである。このような構成とすることで、壁や天井等の取付け面１２に取付けた固定部５に照明器具本体３の背面部に設けた被固定部２を取付けた状態で使用できるのはもちろん、照明器具本体３を取り外した状態で使用する場合には置き台４を兼用する被固定部２を床や机や家具やその他の台等の上に載置することで、照明器具本体３を安定して設定された姿勢で使用できることになる。しかも、照明器具本体３を回動部１５を中心に回動することで、照明角度を広範囲に設定できるものである。また、被固定部２の前面に設けた軸受け部１４又は照明器具本体３の背部から背方に突出したアーム部１３のいずれかに押圧手段により押圧される軸用突部１６を設けると共にいずれか他方に軸用突部１６が回動自在に嵌まり込むはまり込み部１７を設けて軸用突部１６とはまり込み部１７とで回動部１５を構成し、照明器具本体３の前面に対して直交する方向で照明器具本体３の側面を２分割する分割線Ｍを設定し、照明器具本体３を回動して分割線が被固定部２の前面と略平行となった状態で該分割線Ｍと被固定部２の前面との間に回動部１５の回動中心が位置するように設定してあるので、照明器具本体３を回動した場合における固定部５の前面からの突出長さを短くすることができることになる。更に、軸受け部１４又はアーム部１３のいずれかに押圧手段により押圧される軸用突部１６を設けると共にいずれか他方に軸用突部１６が回動自在に嵌まり込むはまり込み部１７を設けて軸用突部１６とはまり込み部１７とで回動部１５を構成するので、照明器具本体３の回動が自在でありながら任意の回動角度で固定できることになり、また、照明器具本体３を被固定部２から外すことも可能となるものである。
【０００６】
また、固定部５に係止部６を設け、被固定部２に係止部６に係止される被係止部７を設けることも好ましい。このような構成とすることで、係止部６と被係止部７との係止により簡単に固定部６に被固定部２を取付けたり、あるいは係止を解除することで取り外すことができるものである。
【０００７】
また、固定部５が所定の厚みを有し、該固定部５の側面に係止部６を設け、被固定部２に被係止部７を設け、被固定部２の固定部５に対する回転により被係止部７を係止部６に係止するように構成することも好ましい。このような構成とすることで、回転という簡単な手段で係止あるいは係止解除ができるものであり、また、照明器具に外力が作用する場合には通常直線的な外力が作用するものであって、このため外力が作用しても被固定部が回転しにくくて外力で不用意に係止が解除されにくいものである。
【０００８】
また、被固定部２を固定部５に取付けた状態で設定以下の力では回転不能で且つ設定以上の力で回転可能とするロック手段８を設け、該ロック手段８が固定部５に設けられる凸部９を有したたわみ片１０と、被固定部２に設けられた凸部９がはめ込まれる凹部１１とで構成してあることも好ましい。このような構成とすることで、簡単な構成のロック手段８により係止が外れないようにできるものである。
【０００９】
また、たわみ片１０が被固定部２の回転方向に対して垂直方向に撓むように構成してあることも好ましい。このような構成とすることで、簡単な構造のロック手段８を構成できるものである。
【００１０】
また、固定部５に被固定部２を取付けた状態で、壁、天井等の取付け面１２に被固定部２が接触しないように設定してあることも好ましい。このような構成とすることで、固定部５に被固定部２を取付ける際に取付け面１２を傷付けることなく、取付けができるものである。
【００１１】
また、凹部１１を貫通孔とし、凹部１１の周囲をたわみ片１０の凸部９が凹部１１より突出するように内方に半球面状に凹んだ半球面状凹み１１ａとすることも好ましい。このような構成とすることで、半球面状凹み１１ａ内に指を入れて凸部９を押すことで凸部９と凹部１１との係合を外すことができ、ロック解除をして固定部５から被固定部２を取り外す操作が簡単にできることになる。
【００１２】
【発明の実施の形態】
以下本発明の実施形態を添付図面に基づいて説明する。図１乃至図３に示すように照明器具本体３の背部には被固定部２が取付けてある。照明器具本体３は前ケース２０と後ケース２１とで外殻が形成してあり、前ケース２０内に照明手段８１が内装してあり、前ケース２０の前面部に照明手段８１からの光を拡散するためのレンズ部２２が接着又は溶着により取付けてある。照明手段８１は例えば複数個のＬＥＤを図４に示すように一直線に配置して構成してある。前ケース２０の外面部には更に照明手段８１の入、切、自動等の動作手段（図示せず）のカバー２４、及び室内の明暗を判断する手段（図示せず）のカバー２６が嵌合により取付けてある。また、前ケース２０内には人体検知手段２７を含む回路部２８が内装され、人体検知手段２７が前ケース２０の孔から露出しており、更に前ケース２０内には電池等の電源手段１を保持するためのホルダー２９が内装され、該ホルダー２９には電池手段１との電気接続を行うための接点部３０が設けてある。
【００１３】
前ケース２０には後ケース２１がねじ３１により取付けてある。後ケース２１には電源蓋３２がフック部３３及び固定リブ３３ａにより後ケース２１の開口部に着脱自在に取付けてあり、この電源蓋３２を外して電源手段１の交換を行うものである。後ケース２１か
ら背方に向けてアーム部１３が突設してあり、該アーム部１３を被固定部２の前面部に設けた軸受け部１４に回動自在に取付けてある。
【００１４】
被固定部２の前面部には図５に示すように、軸受け部１４となる一対の突起が突設してあり、この軸受け部１４にアーム部１３が回動自在に取付けられるのである。
【００１５】
すなわち、図５に示すように、軸受け部１４又はアーム部１３のいずれかに押圧手段６５により押圧される軸用突部１６を設けると共にいずれか他方に軸用突部１６が回動自在に嵌まり込むはまり込み部１７を設けて回動部１５を構成してある（図５においては、軸受け部１６側に押圧手段６５により押圧される軸用突部１６を設け、アーム部１３の両側面に凹形状をしたはまり込み部１７を設けてある）。図５において軸受け部１６は半球状をしていて端部に鍔部１６ａを設けて構成してあり、該軸受け部１６の半球状の部分を軸受け部１４の内壁面部に設けた孔にはめ込んで軸受け部１４内に内装したコイルスプリングにより構成した押圧手段６５により軸用突部１６を軸受け部１４の内壁面部に設けた孔から突出する方向に押圧してある。
【００１６】
ここで、鍔部１６ａの存在により軸用突部１６が内壁面部に設けた孔から脱落しないようになっている。一方、アーム部１３の両側面部は凹形状に凹ませてあってはまり込み部１７が設けてあり、このはまり込み部１７を構成する凹みの内面側の直径は図５（ｃ）に示すように軸用突部１６の半球状をした部分の外面側の直径よりも小さくなっており、このため図５（ｃ）に示すようにはまり込み部１７の開口縁の全周に半球状をした軸用突部１６の外面が環状をした線状態で弾接し軸用突部１６の先端部がはまり込み部１７内に嵌まりこんで抜けにくいようになっている。このように弾性的に軸用突部１６をはまり込み部１７に押圧して軸支することで、アーム部１３を回動した場合任意の回動角度で維持できるものである。また、アーム部１３を大きな力で引くとアーム部１３を軸受け部１４か取り外すことができて、照明器具本体３自体を手で持って携帯用の照明器具として使用できるものである。
【００１７】
被固定部２は後述のように天井や壁等の取付け面１２に取付ける固定部５に着脱できるようになっていると共に、照明器具本体３を床や机や家具やその他の台等の載置面４０の上に載置する場合の置き台４として兼用できるように被固定部２の後面（つまり下面）が置き面部２ａとなっている。図１、図２、図３には置き台４である被固定部２の後面（つまり下面）の置き面部２ａを床や机や家具やその他の台等の載置面４０の上に載置して使用する場合の例を示している。
【００１８】
照明器具本体３は被固定部２に対して回動部１５を中心に図２（ｂ）の矢印のように回動して照明エリア及び照明器具本体３の被固定部２に対する角度を変えることができるようになっている。被固定部２は図７（ｂ）に示すように前面部から背方に略円筒状をした周壁部４１を突設してあり、前面部の背面の中央部に環状のリブ４２が突設してあり、更に、前面部に凹部１１が形成してある。また、略円筒状をした周壁部４１の背方端縁部には周方向に複数等分（実施形態においては３等分）する位置に被係止部７が内方に向けて突出してある。
【００１９】
壁や天井等の取付け面１２に取付けるための部材である固定部５は図７（ａ）に示すように円筒部４３の前端部に前面板部４４を設けてあり、前面板部４４に設けた孔４５からねじを挿入して壁や天井等の取付け面１２に取付けるようになっている。固定部５の円筒部４３の外周部には周方向に複数等分（実施形態においては３等分）する位置に係止部６が外方に向けて突出してある。
【００２０】
そして、図１０（ａ）に示すように背部に被固定部２を取付けた照明器具本体３を壁や天井等の取付け面１２に対して取付けた固定部５に対して正面視で傾けた状態で、隣合う係止部６間に被係止部７が位置するようにして前方より円筒状をした被固定部２の周壁部４１を固定部５の円筒部４３に図１０（ｂ）のようにはめ込み、この状態で図１０（ｂ）の矢印のように固定部５に対して被固定部２を回動して図１０（ｃ）のようにするものであり、この図１０（ｃ）の状態では係止部６に被係止部７が係止され、被固定部２が固定部５に取付けられるものである。
【００２１】
このようにして被固定部２が固定部５に対して回転により取付けられるのであるが、本
発明においては、被固定部２の固定部５に対する回転方向の位置決めと、クリック感による位置決めの確認と、取付け状態を保持するために被固定部２を固定部５に取付けた状態で設定以下の力では回転不能で且つ設定以上の力で回転可能とするロック手段８が設けてある。
【００２２】
図７にはロック手段８の一例が示してあり、この実施形態においては、固定部５の前面板部４４に凸部９を有したたわみ片１０を設けると共に被固定部２の前面部に上記凸部９がはめ込まれる凹部１１を設けてロック手段８が構成してある。そして、上記図１０（ａ）、（ｂ）、（ｃ）の順番で被固定部２の被係止部７を固定部５の係止部６に係止して取付ける場合、図１０（ｂ）の状態では図１１に示すように凸部９が被固定部２の前面部の背面に当たってたわみ片１０がたわんでおり、このように凸部９が被固定部２の前面部の背面に当たった状態で被固定部２を図１０（ｃ）の状態まで回動すると、凸部９と凹部１１とが対向し、図１２に示すように凸部９がたわみ片１０の弾性力により凹部１１に嵌まりこんでクリック感による周方向の位置決めの確認ができると共にこのようにして周方向の位置決めがなされた状態において周方向の回転を規制するためのロックがなされるのである。
【００２３】
ここで、たわみ片１０は被固定部２の回転方向（図１３（ａ）の矢印イ方向）に対して垂直方向（図１３（ａ）の矢印ロ方向）に撓むようになっており、図１３（ｃ）に示すように、被固定部２の前面部の背面と凹部１１の側面とのなす角度をαとした場合、凸部９のたわみ片１０とのなす角度はα＋βであって、α＜α＋βに設定してある。また、凸部９の先端面と側面とのなすコーナ部分がアール形状に面取りしてあり、これらのことにより、図１３（ｂ）のＨ方向に力を加えてロックを解除す場合に、力学上ロックが解除できる構造とすることができる。つまり、α＝（α＋β）の場合にはロック解除ができないものであるが、α＜α＋βに設定することでロック解除ができるのである。そして、βの角度を０°超〜１８０未満の範囲で調整することでロック解除の力を使い勝手、あるいは老若男女等使用者に応じ適正なロック解除力に設定することができるものである。また、凸部９の先端面と側面とのなすコーナ部分をアール形状に面取りすることで、違和感のないロック解除が行えるものである。
【００２４】
壁や天井等の取付け面１２に取付けた固定部５に被固定部２を取付けた状態で、図６に示すように壁、天井等の取付け面１２に被固定部２の後端部が接触しないようになっている。ここで、被固定部２の背面に形成した環状のリブ４２が固定部５の前面板部４４に当接しており、このことにより被固定部２が固定部５側に移動して被固定部２の後端部が壁や天井等の取付け面１２に当たらないようになっており、被固定部２が取付け面１２に当たらないことで取付け面１２が傷つかないようになっている。また、被固定部２の背面に形成した環状のリブ４２が固定部５の前面板部４４に当接することで、被固定部２を固定部５に被せて回動して着脱操作する際の接触面を少なくして回動による着脱操作が容易になるようになっている。
【００２５】
すでに述べたように、照明器具本体３の背部から背方に向けてアーム部１３が突出し、該アーム部１３を被固定部２の前面側に設けた軸受け部１４に前述のように回動自在に軸支して回動部１５を構成しているが、照明器具本体３の前面に対して直交する方向で照明器具本体３の側面を２分割する分割線Ｍを設定した場合、図９（ａ）に示すように照明器具本体３を回動して分割線Ｍが被固定部２の前面と略平行となった状態で該分割線Ｍと被固定部２の前面との間に上記回動部１５の回動中心が位置するように設定してある。つまり、アーム部１３を軸受け部１４に軸支するに当たり、図９（ｂ）のように、分割線Ｍの延長線上にアーム部１３と軸受け部１４との回動中心を位置させた場合に、照明器具本体３を角度γ回動した場合における壁や天井等の取付け面１２からの照明器具本体３の前端までのを長さＬ_２とした場合、図９（ａ）のように照明器具本体３を回動して分割線Ｍが被固定部２の前面と略平行となった状態で該分割線Ｍと被固定部２の前面との間に上記回動部１５の回動中心が位置するように設定したものにおける、照明器具本体３を角度γ回動した場合における壁や天井等の取付け面１２からの照明器具本体３の前端までのを長さＬ1 すると、Ｌ_１＜Ｌ_２となり、照明器具本体３が回動した場合における取付け面１
２からの突出長さを短くでき、少ない突出長さで回動角度を広範囲に取れ、照明角度を広範囲に取れるものである。
【００２６】
前述のように固定部５の前面板部４４に凸部９を有したたわみ片１０を設けると共に被固定部２の前面部に上記凸部９がはめ込まれる凹部１１を設けてロック手段８が構成してあるのであるが、このロック手段８の一構成部位である凹部１１としては図１４に示すように貫通孔により構成してあってもよい。このように貫通孔により凹部１１を構成した場合、図１４（ａ）（ｂ）に示す実施形態では、凹部１１の表面側の周囲を内方に凹んだ半球面状凹み１１ａとしてある。そして、ロック状態では図１４（ｂ）のように該半球面状凹み１１ａの底に設けた凹部１１を構成する貫通孔に凸部９が嵌挿してある。このように凹部１１の表面側の周囲を内方に凹んだ半球面状凹み１１ａとすることで、ロックを解除する場合に、半球面状凹み１１ａに指を押し当てて指により凸部９を押してロック解除をすることができるものである。このようにすることで、ロック状態では指で押さないかぎり、被固定部２を回動してもロックがはずれにくい構造とすることができるものである。
【００２７】
次に、図１５に基づいて被固定部２の固定部５に対する回転方向の位置決めと取付け状態を保持するために被固定部２を固定部５に取付けた状態で設定以下の力では回転不能で且つ設定以上の力で回転可能とするロック手段８の他の実施形態につき説明する。図１５に示す実施形態においては、固定部５の円筒部４３の一部に凸部９を有するたわみ片１０を設け、被固定部２の略円筒状をした周壁部４１に凹部１１を設けてロック手段８を構成してある。この実施形態においては、被固定部２の周壁部４１を固定部５の円筒部４３にはめ込んだはじめの状態では凸部９が被固定部２の周壁部４１の内面に当たってたわみ片１０がたわんでおり、このように凸部９が被固定部２の周壁部４１の内面に当たった状態で被固定部２を回動すると、凸部９と凹部１１とが対向し、凸部９がたわみ片１０の弾性力により凹部１１に嵌まりこんで周方向の位置決めがなされると共に周方向の回転を規制するためのロックがなされるのである。
【００２８】
図１６にはロック手段８の更に他の実施形態が示してあり、この実施形態においては、円筒部４３の周方向に複数等分する位置に設けた各係止部６乃至周壁部４１の周方向に複数等分する位置に設けた各被係止部７の対向面のいずれか一方に突起部５０をいずれか他方に凹所５１を設けてロック手段８が構成してある。図１６に示す実施形態では３つの係止部６にそれぞれ突起部５０を設け、３つの被係止部７にそれぞれ凹所５１を設けてあり、係止部６と被係止部７とを係止した状態で各突起部５０と各凹所５１とが係止して周方向のロックがなされるものである。
【００２９】
ここで、３つの突起部５０は１２０°の開き角度を介して設けてあり、また、３つの凹所５１は１２０°の開き角度を介して設けてあり、このため、係止部６と被係止部７を係止して突起部５０を凹所５１に係止できる位置は被固定部２を固定部５に対して取り付けた位置から更に、１２０°、２４０°回転した位置でも係止部６と被係止部７を係止して突起部５０を凹所５１に係止できることになり、合計３箇所でロックがなされように取付けることができるものである。同様にして係止部６、被係止部７の数、突起部５０、凹所５１の数によりロックできる位置の数が２箇所又は４箇所以上とすることもできるものである。このようにして固定部５に対する被固定部２の固定姿勢を周方向に複数の姿勢に選択できるものである。
【００３０】
ところで、図４に示すように、照明器具本体３の前面部に複数個のＬＥＤのような照明手段８１からの光を拡散するためのレンズ部２２が横方向に長く突出して形成してあるが、このレンズ部２２の長手方向の延長にほぼ人の指１本程度の間隔を隔てて人体検知手段２７が前方に凸状に突出して形成してあるので、照明器具本体３を携帯用の照明器具として手で持って使用する場合、レンズ部２２の延長部分が握り部となり、レンズ部２２を手で塞ぐことなく人体検知手段２７を突出した部分を中心にして滑らないようにして確実に手で掴んで使用できるものである。
【００３１】
なお、図１に示すように、室内の明暗を判断する手段（図示せず）のカバー２６が照明手段８１からの光を拡散するためのレンズ部２２を設けた面と異なる面（実施形態では直角にずれている）に設けてあり、このことにより室内の明暗を判断する手段の感度域を照
明手段８１の照射範囲から避けることができるものである。
【００３２】
図１７には本発明の他の実施形態が示してある。この実施形態においては、被固定部２を固定部５に対して回動して着脱する例につき説明したが、図１７に示すように、壁や天井等の取付け面１２に固定する固定部５に対して被固定部２をスライドにより着脱自在に取付けるようにしてもよい。すなわち、図１７にはスライドにより着脱自在に取付ける一実施形態が示してあり、固定部５に設けた突片状の係止部６の背面側に被固定部２に設けた突片状の被係止部７がスライド自在に係止し、被固定部２のストッパ片７０が固定部５の当たり部７１に当たって支持されるようになっている。もちろんこの実施形態においても、図示を省略しているが被固定部２に照明器具本体３が回動自在に取付けられるものであり、被固定部２を固定部５から外した状態で、被固定部２を置き台として使用することができるものである。
【００３３】
【発明の効果】
本発明の請求項１記載の発明にあっては、上述のように、内部に電源手段を収容した照明器具本体と、照明器具本体の背部から突出したアーム部と、アーム部と回動自在に軸支する軸受け部を前面側に設けた被固定部と、壁や天井等に固定されるものであって被固定部を着脱自在に取付ける固定部とを備えた照明装置において、被固定部を照明器具本体の置き台としてあるので、照明器具本体を壁や天井等の取付け面に取付けて使用できるのはもちろん、固定部から被固定部を外した状態では置き台を兼用する被固定部を床や机や家具やその他の台の上に安定して載せて安定した姿勢で使用できるものである。しかも、照明器具本体を被固定部に回動部により回動自在に取付けてあるので、照明器具本体を回動することで、照明エリアを拡大できるものであり、また照明方向を変えることができるものである。また、被固定部の前面に設けた軸受け部又は照明器具本体の背部から背方に突出したアーム部のいずれかに押圧手段により押圧される軸用突部を設けると共にいずれか他方に軸用突部が回動自在に嵌まり込むはまり込み部を設けて軸用突部とはまり込み部とで回動部を構成し、照明器具本体の前面に対して直交する方向で照明器具本体の側面を２分割する分割線を設定し、照明器具本体を回動して分割線が被固定部の前面と略平行となった状態で該分割線と被固定部の前面との間に回動部の回動中心が位置するように設定してあるので、照明器具本体を回動した場合における取付け面からの突出長さを短くできて、照明器具が邪魔になりにくく、また、突出長さが長いことによる不快感がないものである。更に、軸受け部又はアーム部のいずれかに押圧手段により押圧される軸用突部を設けると共にいずれか他方に軸用突部が回動自在に嵌まり込むはまり込み部を設けてあるので、アームを任意の回動角度で保持することができて角度調整が簡単にできると共に、アームを軸受け部から取り外したり、アームを軸受け部に取付けたりするのが簡単にでき、また、アームを軸受け部から取り外した場合には照明器具本体を携帯用の懐中電灯の代わりとして使用することができるものである。
【００３４】
また、請求項２記載の発明にあっては、上記請求項１記載の発明の効果に加えて、固定部に係止部を設け、被固定部に係止部に係止される被係止部を設けてあるので、固定部に対して被固定部を取り付けるに当たり、係止という簡単な取付けにより取付けることができるものであり、被固定部の着脱が容易にできるものである。
【００３５】

【００３６】
また、請求項４記載の発明にあっては、請求項３記載の発明の効果に加えて、被固定部を固定部に取付けた状態で設定以下の力では回転不能で且つ設定以上の力で回転可能とするロック手段を設け、該ロック手段が固定部に設けられる凸部を有したたわみ片と、被固定部に設けられた凸部がはめ込まれる凹部とで構成してあるので、地震等の振動や人間による衝撃によりロックが外れにくい構造とすることができるものである。
【００３７】
また、請求項５記載の発明にあっては、請求項４記載の発明の効果に加えて、たわみ片
が被固定部の回転方向に対して垂直方向に撓むように構成してあるので、簡単な構成で、ロックが外れにくい構造にできるものである。また、請求項６記載の発明にあっては、請求項１記載の発明の効果に加えて、固定部に被固定部を取付けた状態で、壁、天井等の取付け面に被固定部が接触しないように設定してあるので、被固定部の着脱に当たって取付け面に傷を与えず、また、着脱時に被固定部と取付け面とが摺接することによる不快な音が発生しないものである。
【００３８】
また、請求項７記載の発明にあっては、上記請求項４記載の発明の効果に加えて、凹部を貫通孔とし、凹部の周囲をたわみ片の凸部が凹部より突出するように内方に半球面状に凹んだ半球面状凹みとしてあるので、外したい場合には半球面状凹みとなった凹部に指を入れて凸部を押すことで凸部を凹部から脱離させることができるものであり、また、指で押さないかぎり凸部が凹部から脱離しない構造のものとすることができて、地震や人間が加える衝撃で凸部が凹部から外れない構造とすることもできるものである。

Since it is configured to bend in a direction perpendicular to the rotation direction of the fixed portion, the lock can be easily removed with a simple configuration. Further, in the invention described in claim 6, in addition to the effect of the invention described in claim 1, in a state where the fixed part is attached to the fixed part, the fixed part comes into contact with the mounting surface such as a wall or a ceiling. Therefore, the attachment surface is not damaged when attaching and detaching the fixed portion, and unpleasant sound due to the sliding contact between the fixed portion and the attachment surface during attachment and detachment is not generated.
[0038]
  In the invention according to claim 7, the above-mentionedIn addition to the effect of the invention described in claim 4, since the concave portion is a through-hole, and the convex portion of the flexible piece protrudes from the concave portion around the concave portion, it is a hemispherical concave portion that is recessed inwardly into a hemispherical shape. If you want to remove it, you can remove the convex part from the concave part by putting your finger in the concave part that is a hemispherical concave part and pressing the convex part. It can be of a structure that does not detach from the recess, and can also have a structure in which the projection does not come off from the recess due to an earthquake or an impact applied by a human.
