Description

【０００１】
【産業上の利用分野】
この発明は、天井等の被取付体の開口部に照明器具等の器具を取り付けるための器具の取付装置及びこれを用いる照明器具に関するものである。
【０００２】
【従来の技術】
図８は、例えば実公昭６３−４８０２０号公報に示された従来の取付装置を備えた埋込型照明器具の一部斜視図を示す。図において、１１は天井の上面、１２は天井の下面、１３は天井開口部、１５は天井造営材、３１は器具の取付金具であり操作用つまみ３１ａと係止片３１ｂ及び天井上面接触部３１ｃを有している。また、３２は器具本体、３３は器具本体３２の側壁に設けられた案内スリット、３４は案内スリット３３の周囲に凸凹に形成された波状部、３５は器具本体のフランジである。
【０００３】
次に、従来の取付金具３１による器具本体３２の取り付け方について説明する。まず、取付金具３１を器具本体３２の側壁に設けられた案内スリット３３に、操作つまみ３１ａを器具本体３２の内側に位置させて設置する。このとき、器具本体３２を取り付けようとする天井造営材１５の厚みに応じて、天井上面接触部３１ｃとフランジ３５との距離を充分とっておく。
【０００４】
器具本体３２を天井開口部１３に入れ込むと、取付金具３１が天井開口部１３の周壁に接触しバネ弾性により開口穴に合わせて変形するが、この状態で取付金具３１が天井上面１１を越えるまで押し上げると取付金具３１は元の状態に復元する。
【０００５】
次に器具本体のフランジ３５が天井下面１２に密着するように片方の手で器具本体３２を押さえながら、器具本体３２の内側から操作つまみ３１ａを操作して天井上面接触部３１ｃが天井上面１１に接触するまで取付金具３１を押し下げる。取付金具３１は係止片３１ｂと波状部３４が係合することにより固定される。
【０００６】
【発明が解決しようとする課題】
従来の器具の取付装置は以上のように構成されているので、器具本体の内側に手を入れて小さな部品を操作しなければならず取り付けにくいという問題があった。また、照明器具の取付の際には事前に取付の邪魔となる光源や光反射鏡などを取り外さなければならず、更に、器具取付後は光源や光反射鏡を再装着するという手間を必要とした。
【０００７】
この発明は上記のような問題点を解決するためになされたものであり、器具本体の側方に独立した機構の取付装置を設け取付を容易にするとともに、照明器具の光反射鏡を器具本体と一体の構成として部品構成数を低減し製造コストを下げることを目的とする。
【０００８】

【００１３】
請求項６記載の発明に係る器具の取付装置は、被取付体に形成された開口部に器具本体を挿入して取り付けるようにした器具の取付装置において、被取付体の開口部の表面側開口縁に一端が係合されるとともに左右一対の支持縁と被取付体の開口部の裏面側開口縁に係合する弾性体からなる係合片とを有する可動挟持取付具と、器具本体の外側面に固定された基部からＶ字状に延出され互いに開く方向に付勢される一対の線材からなる保持具とを備え、この保持具の線材を可動挟持取付具の支持縁の内側に摺動自在に圧接し、係合片を器具本体の被取付体への挿入時には保持具の先端部に係止させ、器具本体の取付時には被取付体の裏面側開口縁に係合するようにしたものである。
【００１４】
請求項７記載の発明に係る照明器具は、請求項１または請求項６記載の器具の取付装置において、保持具の先端側を直線状に形成し基部側を保持具の線材が開く方向に湾曲させて形成したものである。
【００１５】
請求項８記載の発明に係る照明器具は、器具本体の側方に請求項１記載の器具の取付装置を設けたものである。
【００１６】

【００１７】
請求項１０記載の発明に係る照明器具は、請求項８または請求項９記載の照明器具において、器具本体を光反射鏡と光反射鏡の開口部周縁に設けられたフランジとから構成したものである。
【００１８】
【作用】
請求項１記載の発明に係る器具の取付装置においては、器具本体を被取付体の開口部に挿入するだけで、保持具の線材の開く力により第１の可動取付具と第２の可動取付具とで被取付体が挟持されて器具が取り付けられる。すなわち、被取付体の開口部に器具本体を挿入し、第１の可動取付具の一端が被取付体の表面側開口縁に係合し動きを停止させられた後さらに器具本体を押し込むと、第１の可動取付具とともに動きを停止させられた第２の可動取付具の支持縁の内側を線材が摺動し、線材の開く力が支持縁の接触抵抗力を上回ると第２の可動取付具が保持具の基部の方向に移動させられ、被取付体の裏面側開口縁に係合した後は線材の開く力により器具本体が被取付体側に引き寄せられ、第１の可動取付具と第２の可動取付具とにより被取付体が挟持されて器具本体が取り付けられる。
【００１９】
請求項２記載の発明に係る器具の取付装置においては、器具本体を被取付体の開口部に挿入するだけで器具を取り付けられるとともに、第２の可動取付具の被取付体側にテーパ面を形成したので、器具本体を被取付体の開口部に挿入する際には開口部をテーパ面が摺動するようにして挿入される。
【００２０】
請求項３記載の発明に係る器具の取付装置においては、器具本体を被取付体の開口部に挿入するだけで器具を取り付けられるとともに、被取付体側に突出させて形成された第２の可動取付具の被取付体の裏面側開口縁に係合する係合部を保持具の基部側に可動としたため、器具本体を被取付体の開口部に挿入する際には第２の可動取付具の係合部が被取付体の表面側開口縁に当たり保持具の基部側に折り曲げられる。
【００２１】
請求項４記載の発明に係る器具の取付装置においては、器具本体を被取付体の開口部に挿入するだけで器具を取り付けられるとともに、第１の可動取付具を線材で構成しているので軽量化できる。
【００２２】
請求項５記載の発明に係る器具の取付装置においては、器具本体を被取付体の開口部に挿入するだけで器具を取り付けられるとともに、保持具の線材を器具本体側へ湾曲させたので、器具本体を被取付体の開口部に挿入する際に線材に取り付けた第１の可動取付具や第２の可動取付具が邪魔にならない。
【００２３】
請求項６記載の発明に係る器具の取付装置においては、係合片を保持具の先端部に係合させて器具本体を被取付体の開口部に挿入し、可動挟持取付具の一端が被取付体の表面側開口縁に係合した後さらに器具本体を押し入れると、線材が支持縁を摺動し係合片が保持具の先端部から外れ、被取付体の裏面側開口縁に係合して被取付体を挟持する。
【００２４】
請求項７記載の発明に係る器具の取付装置においては、器具本体を被取付体の開口部に挿入するだけで器具を取り付けられるとともに、可動挟持取付具が保持具の先端側の直線部分にあるときは、線材の開こうとする作用力よりも支持縁から受ける接触抵抗力の方が大きく可動取付具または可動挟持取付具が保持具の基部の方向に移動させられることはないため、器具本体を被取付体の開口部に挿入し始めてから取り付けられるまでにある程度の余裕がある。
【００２５】
請求項８記載の発明に係る照明器具においては、器具本体内の光源等を取り外さなくても、器具本体を被取付部の開口部に挿入するだけで、保持具の線材の開く力により第１の可動取付具と第２の可動取付具とで被取付体が挟持されて取り付けられる。
【００２６】
請求項９記載の発明に係る照明器具においては、器具本体内の光源等を取り外さなくても、器具本体を被取付部の開口部に挿入するだけで、保持具の線材の開く力により可動挟持取付具により被取付体が挟持されて取り付けられる。
【００２７】
請求項１０記載の発明に係る照明器具においては、器具本体を被取付体の開口部に挿入するだけで取り付けられるとともに、光反射鏡と光反射鏡の開口部周縁に設けられたフランジとを器具本体の一部として構成しているので光反射鏡も同時に取り付けられる。
【００２８】
【実施例】
実施例１．以下、この発明を天井埋込型照明器具に応用した一実施例を図を用いて説明する。図１において、１は内部に光源を取り付ける光反射鏡、２は光反射鏡１の下端周縁に設けられたフランジであり、光反射鏡１とフランジ２とで器具本体を形成している。３は保持具であるＶ形線バネであり、１本の線材の中央部をリング状に巻いて基部とし、基部から線材を延出させて互いに開く方向に付勢されるように形成されている。基部はフランジ２近傍の器具本体外側面に支持固定されている。固定はねじ止めによってもよいが、図３に示すように光反射鏡１の下部の一部を切り起こして基部を挿入し切り起こしの中央部を窪ませて固定すれば、光反射鏡１の表面の出っ張りが少なく取り付けの邪魔にならない。
【００２９】
４はＶ形線バネ３と組み合わされて器具本体を天井に取り付けるための取付金具である。この取付金具４は図１の左側の取付金具を分解して示しているように、第１の可動取付具であるＬ形可動金具６と第２の可動取付具であるＬ形溝付金具８とで構成されている。Ｌ形可動金具６は、下部をＬ形に折り曲げ天井下面接触部５を形成し上部に折り曲げ部７を形成して構成されており、Ｌ形溝付金具８は、左右両側の一部を内側にコの字状に折り曲げて支持縁である溝部９を形成し、下部をＬ形に折り曲げて天井上面接触部１０を形成して構成されている。
【００３０】
Ｌ形可動金具６、Ｌ形溝付金具８及びＶ形線バネ３を組み合わせるには、まずＬ形可動金具６をＬ形溝付金具８の溝部９に通し、折り曲げ部７によりＬ形溝付金具８の上部に引っ掛け、次にＶ形線バネ３の先端部を溝部９に通し摺動可能に弾接させる。この状態ではＶ形線バネ３は溝部９の側部内面に弾性接触しており、Ｌ形可動金具６はＶ形線バネ３の影響を受けない。
【００３１】
また、図２に取付装置を設けた器具本体を被取付体である天井に挿入した図を示しているが、図において、１１は天井上面、１２は天井下面、１３は天井開口部、１４は天井開口部側縁、１５は天井造営材である。
【００３２】
この取付金具４による器具本体の取り付けは次のようにして行なわれる。まず、取付金具４を図１の右側の取付金具４のようにＶ形線形バネ３の先端に位置させる。このときＬ形溝付金具８の天井上面接触部１０は天井開口部１３の径よりも外側へ張り出しているため、器具を天井開口部１３に入れる際には器具本体側へ寄せて天井開口部１３を通す。天井面上部接触部１０が天井上面を越え、器具本体側へ寄せていたＬ形溝付金具８を元に戻すと、図２に示すように、天井上面１１の側縁１４にＬ字形溝付金具８の天井上面接触部１０が引っ掛かり、仮吊りの状態となる。
【００３３】
器具本体を更に押し込むと、Ｌ形可動金具６の天井下面接触部５が天井下面１２に接触するまで、取付金具４はＶ形線バネ３の先端に位置したまま器具本体とともに上方に移動する。すなわち、Ｖ形線バネ３を挟み込んでいるＬ形溝付金具８が器具本体とともに上方へ移動し、折り曲げ部７によりＬ形溝付金具８に引っ掛けられているＬ形可動金具６も上方へ移動する。
【００３４】
Ｌ形可動金具６の天井下面接触部５が天井下面１２に係合した後、更に器具本体を押し込むと、Ｌ形可動金具６は天井下部１２により動きを停止させられ、Ｌ形溝付金具８も折り曲げ部７より上方へは移動できなくなるので、Ｖ形線バネ３がＬ形溝付金具８の溝部９をスライドし始める。Ｖ形線バネ３の開こうとする作用力が、溝部９に当たっている接触抵抗力を上回ると、Ｖ形線バネ３が開きながら上方にスライドするとともにＬ形溝付金具８は下方に移動させられる。Ｖ形線バネ３の開こうとする作用力が、溝部９に当たっている接触抵抗力を上回った後は、人が器具本体を押し上げる力をほとんどかけなくても、Ｖ形線バネ３の力により器具本体が上方へ引き上げられる。Ｌ形溝付金具８の天井上面接触部１０が天井上面に係合すると、Ｌ形溝付金具８の下方への動きは止まるため、Ｖ形線バネ３のみ、すなわち器具本体のみが上方へ移動し、最終的にフランジ２がバネ弾性力により天井下面１２に密着させられて取り付けられる。図４（ａ）に器具本体が取り付けられたときの取付金具４及びＶ形線バネ３の状態を正面から見た図を示す。また、その断面図を図４（ｂ）に示す。天井下面への密着はＶ形線バネに依っているので、振動などにより器具がずれ落ちて隙間が発生する恐れはない。
【００３５】
以上説明したように、この実施例においては、Ｖ形線バネ３の開こうとする作用を応用する際に、Ｖ形線バネ３とＬ形溝付金具８とが互いに可動側、固定側となって機能する。すなわち、Ｌ形溝付金具８はＶ形線バネ３が溝部９をスライドする際に固定されたままではなく、Ｖ形線バネ３の開こうとする力によって下方に移動させられ天井上面接触部１０が天井上面に当接するまでは可動である。このように、取付金具４が独立した構造で器具本体の側方に取り付けられて動作するため、器具本体の構造に依存する度合いが低く、活用範囲が広がるとともに設計の制約も少ない。
【００３６】
また、この実施例における取付金具によれば、取り付けに際して器具本体内部から小さな部品を操作する必要がなく、器具本体を押し込むだけで取り付けることができるため、取り付け時間を短縮できる。また、器具本体内部からの操作がなくなるので、光源や光反射鏡１などが結合されたまま作業を行なうことができる。さたに、光反射鏡等を器具本体と一体に形成しておくことができるため、部品構成数を低減でき、しかも光反射鏡等の落下の恐れがない。
【００３７】
また、器具の取り外しの際も、器具本体はＶ形線バネ３の保持力のみで取り付いているので、器具本体を押し下げるだけでＬ形溝付金具８の溝９をＶ形線バネがスライドして降り、簡単に取り外せる。さらに、器具本体が天井開口部１３から完全に外れる前に、Ｌ形溝付金具８の天井上面接触部１０が天井上面１１に接触し図２に示すような仮吊りの状態となり、Ｖ形線バネ３の先端に設けられた曲げ部が溝部９の上部に当たるため、器具の落下の恐れはない。
【００３８】
なお、この実施例においては取付金具４を器具本体側方の２か所に設けているが、器具本体の径が大きく重い場合には、３か所に設ければ、より確実に安定して取り付けることができる。
【００３９】
また、Ｖ形線バネ３は直線状でもよいが、図１に示すように湾曲させてもよい。このように形成すれば、薄い天井造営材でＶ形線バネ３の根元付近に溝９がきても開き力が弱くならず、天井造営材１５の種々の厚みに対応できる。バネの曲率はバネの太さ、溝部９の幅、器具の重さ等によって適当な値に決められる。また、曲げ方は、図１に示すようにＬ状に曲げても、Ｒ状に曲げてもよい。
【００４０】
実施例２．図５に本発明の第２の実施例を示す。取付金具４は上記の実施例１と同様であり、取付の動作もほぼ同様であるが、この実施例においてはＶ形線バネ１６を途中で折り曲げ、先端側を直線状に形成し基部側を湾曲させて形成している。Ｖ形線バネ１６をこのように形成すれば、Ｖ形線バネ１６が溝部９をスライドするときに、溝部９がＶ形線バネ１６の先端部から折り曲げ部までの間の直線部分にあるときはバネの開こうとする作用力よりも溝部９から受ける接触抵抗力の方が大きいため、Ｌ形溝付金具８が下方に押し下げられることはない。したがって、器具本体を天井開口部１３に挿入する際に、すぐにＶ形線バネ１６が開いて器具本体が取り付けられることはなく、ある程度の遊びがあるため取り付け易い。
【００４１】
実施例３．図６に本発明の第３の実施例を示す。図において、１８は一端に天井下面接触部１７を有し他端に折り曲げ部１９を有するＬ形可動金具であり、２０は線バネ３が内側に圧接する溝部２１と天井上面接触部２２を有するＬ形溝つき金具である。この実施例においてはＬ形溝付金具２０の天井上面接触部２２を溝部２１と同じように器具本体側に折り曲げて形成し、Ｌ形可動金具１８と組み合わせた際にテーパが形成されるように構成されている。このように形成すれば、器具本体を天井開口部に挿入する際、天井上面接触部２２が邪魔になることなく、テーパが天井開口部１３を摺動するため容易に挿入することができる。その他の取付の動作は上記の実施例１と同様である。
【００４２】
また、折り曲げ部１９は図１等に示すものよりも大きく形成されているが、このように形成しても同様の働きをする。
【００４３】
実施例４．図７に本発明の第４の実施例を示す。この実施例においては、Ｌ形溝付金具２４の天井上面接触部２５をコイルバネ２３を組み合わせることにより可動形としている。取付金具をこのような形状にすれば、天井開口部１３への挿入の際に天井上面接触部２５が天井開口部１３の縁に当たると下方へ折れ、天井を越えるとコイルバネ２３の力により元の位置に復元するため、取付金具４を器具本体側に寄せる必要はなく、器具の挿入が容易になる。その他の取付の動作は上記の実施例１と同様である
【００４４】
実施例５．図８に本発明の第５の実施例を示す。この実施例においてはＬ形可動金具２６を線材で形成した。Ｌ形可動金具２６の上端はＬ形溝付金具８の天井上面接触部に係合されており、この部分がＬ形溝付金具８の上方への動きを規制する働きをする。このように形成しても、上記の実施例１と同様の動作をして器具が取り付けられ、しかもＬ形可動金具を線材で形成したため軽量化が図れ、組立が容易である。
【００４５】
実施例６．図９に本発明の第６の実施例を示す。取付金具４の形状は上記実施例１と同様であり、天井への取付の動作もほぼ同様であるが、この実施例においてはＶ形線バネ２７を器具本体内側へ曲率を持って曲げて形成している。曲げの程度は、取付金具４をＶ形線バネ２７の先端に設置させたときに天井上面接触部１０が天井開口部１３の縁よりも内側に位置し、天井下面接触部５のみが天井開口部１３の縁に引っ掛かるように調整されている。このように形成すれば、取付金具４を器具本体側に寄せる必要がなく、器具の挿入が容易になる。
【００４６】
実施例７．図１０に本発明の第７の実施例を示す。この実施例においては、上記の実施例におけるＬ形溝付金具とＬ形可動金具を一体に形成して可動挟持取付具としている。可動挟持取付具はバネ鋼等で一体に形成されており、器具本体を天井開口部へ取り付ける際に天井上面に係合する係合片である板バネ２８と、天井下面に接触する天井下部接触部２９とを有している。３０はＶ形線バネ、３０ａはＶ形線バネの先端部に形成された湾曲部である。
【００４７】
器具本体の挿入時には板バネ２８をＶ形線バネの湾曲部３０ａに引っ掛けておき、器具本体の挿入を容易にする。器具本体を更に押し込むと板バネ２８がＶ形バネの先端３０ａから外れ、天井上面に接触して天井下面接触部２９とともに天井造営材を挟持して器具本体が取り付けられる。
【００４８】
この実施例によれば、取付金具を一体の部品として構成できるとともに、板バネ２８の湾曲部３０ａへの引っ掛かりを調整することにより湾曲部３０ａから外れるタイミングを調整できる。なお、図１０においては板バネ２８を天井下面接触部２９の位置で折り曲げて形成しているが、天井の厚みに応じて折り曲げの位置を調節してもよい。
【００４９】
以上、実施例１ないし実施例７においては本発明を天井に取り付ける照明器具に適用した例を示したが、本発明は壁面等に形成された開口部に取り付けられる他の器具にも応用できるものである。

[0028]
【Example】
Example 1. Hereinafter, an embodiment in which the present invention is applied to a ceiling-embedded lighting fixture will be described with reference to the drawings. In FIG. 1, reference numeral 1 denotes a light reflecting mirror for attaching a light source therein, and 2 denotes a flange provided at the lower end periphery of the light reflecting mirror 1, and the light reflecting mirror 1 and the flange 2 form an instrument body. Reference numeral 3 denotes a V-shaped wire spring which is a holding tool, and is formed so that a central portion of one wire is wound in a ring shape to be a base, and the wires are extended from the base and are urged in the opening direction. Yes. The base is supported and fixed to the outer surface of the instrument body near the flange 2. Fixing may be performed by screwing. However, as shown in FIG. 3, if the base of the light reflecting mirror 1 is cut and raised, the base is inserted, and the central portion of the cut and raised is recessed and fixed, the light reflecting mirror 1 can be fixed. There is little protrusion on the surface and it does not interfere with installation.
[0029]
Reference numeral 4 denotes a mounting bracket that is combined with the V-shaped wire spring 3 to mount the instrument body on the ceiling. As shown in the exploded view of the left-side mounting bracket in FIG. 1, the mounting bracket 4 is an L-shaped movable bracket 6 that is a first movable bracket and an L-shaped grooved bracket 8 that is a second movable bracket. It consists of and. The L-shaped movable metal fitting 6 is formed by bending the lower part into an L shape to form the ceiling lower surface contact part 5 and forming the bent part 7 at the upper part. The groove 9 as a support edge is formed by bending it into a U-shape, and the ceiling upper surface contact portion 10 is formed by bending the lower part into an L shape.
[0030]
In order to combine the L-shaped movable bracket 6, the L-shaped grooved bracket 8 and the V-shaped wire spring 3, first the L-shaped movable bracket 6 is passed through the groove 9 of the L-shaped grooved bracket 8, and the bent portion 7 causes the L-shaped groove. The top of the metal fitting 8 is hooked, and then the tip of the V-shaped wire spring 3 is slidably elastically passed through the groove 9. In this state, the V-shaped wire spring 3 is in elastic contact with the inner surface of the side portion of the groove 9, and the L-shaped movable metal fitting 6 is not affected by the V-shaped wire spring 3.
[0031]
Moreover, although the figure which inserted the instrument main body which provided the attachment apparatus in FIG. 2 in the ceiling which is a to-be-attached body is shown, 11 is a ceiling upper surface, 12 is a ceiling lower surface, 13 is a ceiling opening part, 14 is a ceiling opening part. A ceiling opening side edge, 15 is a ceiling construction material.
[0032]
The fixture body is attached by the attachment bracket 4 as follows. First, the mounting bracket 4 is positioned at the tip of the V-shaped linear spring 3 like the mounting bracket 4 on the right side of FIG. At this time, the ceiling upper surface contact portion 10 of the L-shaped grooved metal fitting 8 projects outward from the diameter of the ceiling opening portion 13, and therefore, when the appliance is put into the ceiling opening portion 13, the ceiling opening portion is moved toward the appliance body side. 13 is passed. When the L-shaped grooved fitting 8 that has been moved toward the instrument body side when the ceiling surface upper contact portion 10 has passed the ceiling upper surface is restored, as shown in FIG. 2, the side edge 14 of the ceiling upper surface 11 has an L-shaped groove. The ceiling upper surface contact portion 10 of the metal fitting 8 is caught and is in a temporarily suspended state.
[0033]
When the instrument body is further pushed in, the mounting bracket 4 moves upward together with the instrument body while being positioned at the tip of the V-shaped wire spring 3 until the ceiling lower surface contact portion 5 of the L-shaped movable bracket 6 contacts the ceiling lower surface 12. In other words, the L-shaped grooved fitting 8 sandwiching the V-shaped wire spring 3 moves upward together with the instrument body, and the L-shaped movable fitting 6 hooked on the L-shaped grooved fitting 8 by the bent portion 7 also moves upward. To do.
[0034]
After the ceiling lower surface contact portion 5 of the L-shaped movable metal fitting 6 is engaged with the ceiling lower surface 12, when the instrument body is further pushed in, the movement of the L-shaped movable metal fitting 6 is stopped by the ceiling lower part 12, and the L-shaped grooved metal fitting 8 Since it cannot move upward from the bent portion 7, the V-shaped wire spring 3 starts to slide on the groove portion 9 of the L-shaped grooved metal fitting 8. When the acting force to open the V-shaped wire spring 3 exceeds the contact resistance force hitting the groove portion 9, the V-shaped wire spring 3 slides upward while opening and the L-shaped grooved metal fitting 8 is moved downward. . After the acting force to open the V-shaped wire spring 3 exceeds the contact resistance force hitting the groove 9, the force of the V-shaped wire spring 3 can be applied by the force of the V-shaped wire spring 3 even if a person hardly applies a force to push up the device body. The main body is pulled upward. When the ceiling top surface contact portion 10 of the L-shaped grooved fitting 8 is engaged with the ceiling top surface, the downward movement of the L-shaped grooved fitting 8 stops, so that only the V-shaped wire spring 3, that is, only the instrument body moves upward. Finally, the flange 2 is attached in close contact with the ceiling lower surface 12 by the spring elastic force. The figure which looked at the state of the attachment metal fitting 4 and the V-shaped wire spring 3 when an instrument main body was attached to FIG. 4 (a) from the front is shown. Also shows a sectional view thereof in Figure 4 (b). Since the close contact with the lower surface of the ceiling depends on the V-shaped wire spring, there is no possibility that a gap may be generated due to the instrument slipping off due to vibration or the like.
[0035]
As described above, in this embodiment, when the action of opening the V-shaped wire spring 3 is applied, the V-shaped wire spring 3 and the L-shaped grooved fitting 8 are connected to each other on the movable side, the fixed side, and the like. Function. That is, the L-shaped grooved metal fitting 8 is not fixed when the V-shaped wire spring 3 slides on the groove 9, but is moved downward by the force of the V-shaped wire spring 3 to open, and the ceiling upper surface contact portion. It is movable until 10 abuts on the ceiling surface. As described above, since the mounting bracket 4 operates with being attached to the side of the instrument main body with an independent structure, the degree of dependence on the structure of the instrument main body is low, the utilization range is widened, and design restrictions are few.
[0036]
Further, according to the mounting bracket in this embodiment, it is not necessary to operate a small part from the inside of the instrument main body at the time of mounting, and the mounting can be shortened by simply pushing the instrument main body.

In addition, since the light reflecting mirror or the like can be formed integrally with the instrument body, the number of components can be reduced, and there is no fear of the light reflecting mirror or the like being dropped.
[0037]
Also, when removing the instrument, the instrument body is attached only by the holding force of the V-shaped wire spring 3, so that the V-shaped wire spring slides on the groove 9 of the L-shaped grooved metal fitting 8 simply by pushing down the instrument body. It can be easily removed. Furthermore, before the instrument main body is completely removed from the ceiling opening 13, the ceiling upper surface contact portion 10 of the L-shaped grooved fitting 8 comes into contact with the ceiling upper surface 11 to be in a temporarily suspended state as shown in FIG. Since the bent part provided at the tip of the spring 3 hits the upper part of the groove part 9, there is no fear of dropping of the instrument.
[0038]
In this embodiment, the mounting bracket 4 is provided at two locations on the side of the instrument body. However, if the instrument body is large and heavy, it can be more reliably and stably provided at three locations. Can be attached.

In this embodiment, the V-shaped wire spring 16 is bent halfway, the tip side is formed in a straight line, and the base side is formed. It is curved and formed. When the V-shaped wire spring 16 is formed in this way, when the V-shaped wire spring 16 slides in the groove portion 9, the groove portion 9 is in a linear portion between the tip portion of the V-shaped wire spring 16 and the bent portion. Since the contact resistance force received from the groove portion 9 is greater than the acting force to open the spring, the L-shaped grooved fitting 8 is not pushed downward. Therefore, when the instrument main body is inserted into the ceiling opening 13, the V-shaped wire spring 16 is not immediately opened and the instrument main body is not attached.
[0041]
Example 3 FIG. FIG. 6 shows a third embodiment of the present invention. In the figure, 18 is an L-shaped movable bracket having a ceiling lower surface contact portion 17 at one end and a bent portion 19 at the other end, and 20 has a groove portion 21 and a ceiling upper surface contact portion 22 to which the wire spring 3 is pressed inward. L-shaped grooved fitting. In this embodiment, the ceiling upper surface contact portion 22 of the L-shaped grooved metal fitting 20 is formed to be bent to the instrument body side in the same manner as the groove portion 21 so that a taper is formed when combined with the L-shaped movable metal fitting 18. It is configured. If it forms in this way, when inserting an instrument main body in a ceiling opening part, since a taper slides the ceiling opening part 13 without the ceiling upper surface contact part 22 becoming obstructive, it can insert easily. Other mounting operations are the same as those in the first embodiment.
[0042]
The bent portion 19 is formed to be larger than that shown in FIG. 1 and the like, but the same function is achieved even if formed in this way.
[0043]
Example 4 FIG. 7 shows a fourth embodiment of the present invention. In this embodiment, the ceiling upper surface contact portion 25 of the L-shaped grooved metal fitting 24 is made movable by combining a coil spring 23. If the mounting bracket has such a shape, when the ceiling upper surface contact portion 25 hits the edge of the ceiling opening portion 13 when inserted into the ceiling opening portion 13, it will be bent downward, and when it exceeds the ceiling, the original force is applied by the force of the coil spring 23. In order to restore the position, it is not necessary to bring the mounting bracket 4 toward the instrument body, and the instrument can be easily inserted. Other mounting operations are the same as those in the first embodiment.
Embodiment 5 FIG. FIG. 8 shows a fifth embodiment of the present invention. In this embodiment, the L-shaped movable metal fitting 26 is formed of a wire material. The upper end of the L-shaped movable metal fitting 26 is engaged with the ceiling upper surface contact portion of the L-shaped grooved metal fitting 8, and this part functions to restrict the upward movement of the L-shaped grooved metal fitting 8. Even if formed in this way, the same operation as in the first embodiment is performed, the instrument is attached, and since the L-shaped movable metal fitting is formed of a wire material, the weight can be reduced and the assembly is easy.
[0045]
Example 6 FIG. 9 shows a sixth embodiment of the present invention. The shape of the mounting bracket 4 is the same as that of the first embodiment, and the operation of mounting to the ceiling is substantially the same. In this embodiment, the V-shaped wire spring 27 is bent to the inside of the instrument body with a curvature. doing. The degree of bending is such that when the mounting bracket 4 is installed at the tip of the V-shaped wire spring 27, the ceiling upper surface contact portion 10 is positioned inside the edge of the ceiling opening 13, and only the ceiling lower surface contact portion 5 is open to the ceiling. It is adjusted to be caught on the edge of the portion 13. If formed in this way, it is not necessary to bring the mounting bracket 4 to the instrument body side, and the instrument can be easily inserted.
[0046]
Example 7 FIG. 10 shows a seventh embodiment of the present invention. In this embodiment, the L-shaped grooved fitting and the L-shaped movable fitting in the above-described embodiment are formed integrally to form a movable holding fixture.
