【発明の属する技術分野】
本発明は、例えば、照度センサ、温度センサ、リモコン受光部、照明器具の如き埋込型機器の取付装置に関するものである。
【０００２】
【従来の技術】
図７は、例えば、特開平４ー６２７０９号公報に開示された従来の天井埋込型照明器具の取付装置の一例を示す斜視図である。１は円筒状の本体、２は天井取付バネで、この天井取付バネ２を本体１に取り付けできるようになっている。そして、天井取付バネ２には、係止爪３、耳片４ａ，４ｂ、取付ネジ５を挿通するネジ挿通孔６ａ，６ｂが設けられており、また、本体１には、天井取付バネ２の係止爪３を受け入れる爪係止孔７ａ，７ａ、耳片４ａ，４ｂを受け入れる耳片係止孔８ａ，８ｂ及び取付ネジ５を受け入れる長孔９が設けられている。
【０００３】
そして、天井取付バネ２の係止爪３を本体１の爪係止孔７ａ（又は７ｂ）に係止させ、耳片４ａ，４ａを耳片係止孔８ａ，８ｂに係止させた後、取付ネジ５を天井取付バネ２のネジ挿通孔６ａ，６ｂから本体１の長孔９に挿通してネジ止めし、本体１に固定する。この場合、係止爪３を爪係止孔７ａ，７ｂのどちらに入れるかで、天井の厚み変化に対応させている。
【０００４】
また、図８は上記公報に記載された他の例で、図７で示した天井取付バネ２の耳片４ａ，４ｂと円筒状の本体１の耳片係止孔８ａ，８ｂを省略して、本体１に振れ止め用のガイド溝７を設けたもので、天井取付バネ２を本体１のガイド溝７に嵌合させ、取付ネジ５で固定する。
【０００５】
【発明が解決しようとする課題】
上記のように構成した従来の天井埋込型照明器具の取付装置によれば、円筒状の本体１と天井取付バネ２は、取付ネジ５を使って固定しているだけであり、係止爪３を爪係止孔７ａ（７ｂ）に挿入させ耳片４ａ，４ｂを耳片係止孔８ａ，８ｂにさせている部分はずれ防止のためだけのものである。また、本体１は円筒状であるため天井取付バネ２と本体１との接触面が狭い。このため、本体１を設置場所に埋め込み設置する場合や設置した後に、安定かつ安全な状態を保持することは困難であった。
【０００６】
本発明は上記のような課題を解決するためになされたもので、常時、安定かつ安全な設置状態を保持できる埋込型機器の取付装置を得ることを目的とする。
【０００７】
【課題を解決するための手段】

【００１０】
上記の埋込型機器の取付装置において、本体側係止部として係止突部を設け、前記バネ取付片側係止部として係止孔を設けて、前記係止突起部に前記係止孔を嵌合させ係止させるようにしたものである。
【００１１】
上記の埋込型機器の取付装置において、係止突起部に嵌合する係止孔を複数箇設け、係止孔をスライド方向にずらして係止突起部に係止することにより埋込面の厚さに対応するようにしたものである。
【００１３】
上記の埋込型機器の取付装置において、取付バネのバネ係止片に落下防止用爪を設けたものである。
【００１４】
【発明の実施の形態】
実施形態１
図１は本発明の第１の実施形態の斜視図である。１０ほぼ円筒状で、上部は天板１１で閉塞され、下部につば部１２が設けられて内部に例えばセンサを有する埋込型照度センサの本体（以下本体という）で、１３，１３は本体１０の側壁に対向して設けられたバネ取付部である。２０はほぼＶ字状で例えばバネ鋼からなる一対の取付バネ（図には一方だけ示してある）で、本体１０のバネ取付部１３，１３に差し込んで取り付けられる。
【００１５】
まず、本体１０のバネ取付部１３（２箇所に設けられた一方の側のみ）について詳述すると、１４はバネ取付部１３の外側壁で、本体１０の一部を上下方向に平面状に切除したものである。１５は外側壁１４のほぼ中央部付近から本体１０の中心部方向に向かって設けられた凹状のバネ係止部で、１６はバネ係止部１５の最奥部に設けられた平面状の取付背板（底面）、１７ａ，１７ｂは取付背板１６の両側部に外側方向に向けて溝部を形成した取付ガイドで、これらにより、断面ほぼＴ字状に形成されている。１８は取付背板１６のほぼ中央近傍に設けられた係止突起部で、例えば下側方向に狭くなるテーパ部によって形成されている。
【００１６】
次に、取付バネ２０（図には一方の側のみ示してある）について詳述すると、２１はほぼＶ字状の取付バネ２０の一方の側（バネ取付部１３に差し込む側）に設けられたバネ取付片で、その両側部には背面に突設したバネガイド部２２ａ，２２ｂが設けられている。そして、バネ取付片２１を本体１０のバネ係止部１５の取付背板１６に沿って上方からその両側縁を取付ガイド１７ａ，１７ｂに差し込んで、バネガイド部２２ａ，２２ｂでガタを抑えて下方向にスライドさせるようになっている。２３ａ，２３ｂはバネ取付片２１の上下方向の中央部付近に設けられた上部係止孔及び下部係止孔で、そのいずれかを本体１０のバネ係止部１５の係止突起部１８に嵌合させて固定するようになっている。
２４は取付バネ２０の他方の側（天井等の埋込部に係止させる側）に設けられたバネ係止片、２５はバネ係止片２４の先端部に外側方向に折り曲げて形成した落下防止爪である。
【００１７】
上記のように構成した第１の実施形態の作用を説明する。埋込型機器の取付装置の本体１０に設けられたバネ係止部１５に上方から取付バネ２０のバネ取付片２１を取付背板１６に沿って差し込み、取付ガイド１７ａ，１７ｂでガイドして下方向にスライドさせる。そして、バネ取付片２１の上部係止孔２３ａと下部係止孔２３ｂのいずれか一方を係止突起部１８に嵌合させて係止する。なお、他方の側のバネ取付部１３にも同様にして取付バネ２０を取付ける。
【００１８】
このようにして、本体１０に取付バネ２０，２０を取付けた取付装置により埋込型機器を天井や壁等に取付けるには、次のようにして行う。まず、図２に示すように、比較的厚い材料からなる天井、壁等の埋込面２６に設けた埋込孔２７に埋込型機器を取付ける場合について説明する。この場合は、バネ取付片２１の下方向に設けられた下部係止孔２３ｂを係止突起部１８に嵌合して係止させ、バネ係止片２４が本体１０の側面のやや上方に位置するようにしておく。なお、４０は本体１０内に設けた例えばセンサの如き内部機器である。
【００１９】
この状態にしてから、取付バネ２０，２０のバネ係止片２４，２４を本体１０側に圧縮して折り曲げ、その状態のままで本体１０を埋込孔２７の下方から埋込孔２７内に挿入する。そして、つば部１２が埋込面に当接すると、取付バネ２０，２０のバネ係止片２４，２４がその復元力によって本体１０の外側方向に付勢され、埋込孔２７の側壁に圧接されて固定される。その後、本体１０の取付け方向を調整する。
なお、埋込型機器を埋込孔２７に挿入した際の、及び取付バネ２０，２０が本体１０の外側方向に付勢されその反発力によって埋込型機器が埋込孔２７に固定された際の、埋込型機器の落下は落下防止爪２５によって防止される。
【００２０】
次に、この埋込型機器を、図３に示す比較的薄い埋込面２８に取付ける場合を説明する。図２では、取付バネ２０の下部係止孔２３ａを本体１０の係止突起部１８に係止させたが、図３に示すように、取付バネ２０のバネ取付片２１を取付背板１６に沿って下方向にずらして、係止突起部１８に上方係止孔２３ｂを嵌合して係止させる。
【００２１】
この状態にしてから、取付バネ２０，２０のバネ係止片２４，２４を本体１０側に圧縮して折り曲げ、その状態のままで本体１０を埋込孔２９の下方から埋込孔２９内に挿入すると、取付バネ２０，２０のバネ係止片２４，２４がその復元力によって本体１０の外側方向に付勢され、埋込孔２９の側壁に圧接されて固定される。その後、本体１０の取付け方向を調整する。
【００２２】
このように、本実施形態によれば、埋込型機器の取付装置の本体１０に設けたバネ係止部１５の取付背板１６を平面状に形成したので、取付バネ２０を本体１０に取り付けたときに両者の接触面が従来よりも広くなり、安定かつ確実に固定され、強度が大となる。
また、本体１のバネ係止部１５に取付ガイド１７ａ，１７ｂと係止突起部１８を設けて、取付バネ２０を取付ガイド１７ａ，１７ｂでガイドしつつスライドさせ、係止突起部１８を上部又は下部係止孔２３ａ，２３ｂに嵌合させるようにしたので、取付バネ２０の強度が増し本体１０に容易、正確かつ確実に固定することができる。
【００２３】
また、バネ係止部１５を本体１０の中心部方向に向かって凹状に形成したので、従来のように埋込面に本体とバネを合わせた大きさの埋込孔を設ける必要はなく、埋込孔の大きさを最小限にすることができる。そして、本体１０を埋込孔に埋め込む方向を自由に設定することができるので作業が容易になり、また安定したバネの反発力と構造によって確実で安定、かつ安全に取付けることができる。
【００２４】
また、取付バネ２０の２箇所に上部、下部係止孔２３ａ，２３ｂを設け、埋込面の厚さに応じて係止突起部１８に係止する係止孔の位置をずらして嵌合するようにしたので、例えば９ｍｍ〜１８ｍｍ厚さの天井材はもちろんのこと、５ｍｍ程度の厚さの壁の金属パーテーションや２０ｍｍ以上の厚さのシステム天井等の、埋め込む箇所の材料の厚さ変化に対応して安定して取付けることができる。
【００２５】
また、取付バネ２０には落下防止爪２５を設けたので、取付け時及び取付け後に埋込型機器の落下を防止でき、安全性を保持することができる。
また、取付バネ２０の取付けを差し込み式にしたので、取付バネ２０を本体１０に固定するためのボルト、ナット等のネジ部品等が不要になり、省部品化、製造の容易化、効率向上が実現できる。
【００２６】
実施形態２
第１の実施形態では、取付バネ２０のバネ取付片２１の上下方向に上部係止孔２３ａと下部係止孔２３ｂを２箇所設けたが、本実施形態では係止孔を上下方向に３箇所以上設けたものである。
本実施形態によれば、第１の実施形態に示した場合と同様の効果を有するが、さらに、取付バネ２０の３箇所以上に係止孔を設け、埋込面の厚さに応じて係止突起部１８に係止する係止孔の位置をずらすようにしたので、埋込面の厚さ変化に緻密に対応してより安定した状態で取付けることができる。
【００２７】
実施形態３
第１、第２の実施形態では、取付バネ２０のバネ取付片２１に係止孔２３ａ，２３ａを設け、本体１０の取付背板１６に係止突起部１８を設けたが、本実施形態では取付バネ２０のバネ取付片２１に係止突起部を設け、本体１０の取付背板１６に凹状の係止孔を設けて、これらの係止突起部を凹状の係止孔に嵌入して係止させるようにしたものである。
本実施形態によれば、第１の実施形態に示した場合と同様の効果を有するが、さらに、係止突起部と係止孔の位置選定を多様化することができる。
【００２８】
実施形態４
第１、第２、第３の実施形態では、ほぼＶ字状の取付バネ２０，２０を別個に２個設けたが、本実施形態では、図４に示すように、取付バネ２０，２０のバネ取付片２１，２１の上部を連結部２０ａにより相互に連結して門型に形成し、１個の取付バネとして、その連結部２０ａを本体１０の上面に接触させて係止するようにしたものである。なお、連結部２０ａを本体１０の天板１１にねじ止めしてもよい。
従って、本実施形態によれば、第１の実施形態に示した場合と同様の効果を有するが、さらに、取付バネ２０のバネ取付片２１，２１の上部を相互に連結したので取付バネ２０を本体１０により確実に固定することができる。
【００２９】
実施形態５
図５は本発明の第５の実施形態の斜視図である。１０はほぼ円筒状で、上部に天板１１が取付けられ、下部につば部１２を有し、内部に例えば照度センサのセンサを有する埋込型機器の取付装置の本体で、１３，１３は本体１０の側壁の対向位置に設けた一対のバネ取付部である。１６はバネ取付部１３に設けた取付背板で、本体１０の一部を平面状に切除して形成したものである。３０ａ，３０ａはバネ取付部１３の取付背板１６に対向して設けたＬ字状の係止爪で、上方から差し込まれた取付バネ２０のバネ取付片２１の両側をガイドしてスライドさせる。１８は係止爪３０ａ，３０ｂの間に設けられた係止突起部である。
【００３０】
２０は例えばバネ鋼からなるほぼＶ字状の一対の取付バネで、本体１０のバネ取付部１３，１３に差し込んで取り付けられる。
２１はほぼＶ字状の取付バネ２０の一方の側（バネ取付部１３に取付ける側）に設けられたバネ取付片で、その両側にはガタ防止用のバネガイド部２２ａ，２２ｂが設けられている。そして、バネ取付片２１を取付背板１７に沿って係止爪３０ａ，３０ｂの上方向から差し込んで、その両縁部を係止爪３０ａ，３０ｂでガイドして下方向にスライドさせ、取付バネ２０を本体１０に取付けるようにしてある。２３はバネ取付片２１に設けられた係止孔で、取付背板１６の係止突起部１８に嵌入して係止するようになっている。
【００３１】
上記のように構成した本実施形態の作用を説明する。取付バネ２０のバネ取付片２１を、本体１０の取付背板１６に沿って係止爪３０ａ，３０ｂの上方向から差し込んで、その両縁部を係止爪３０ａ，３０ｂでガイドして下方向にスライドさせ、つば部１２を埋込面２８に当接させてバネ取付片２１に設けられた係止孔２３を取付背板１６の係止突起部１８に嵌合して係止させる。
【００３２】
なお、上記の実施形態において、取付バネ２０のバネ取付片２１に係止突起部を設け、本体１０の取付背板１６に凹状の係止孔を設けて、取付バネ２０の係止突起部を本体１０の係止孔に嵌入して係止させるようにしてもよい。
また、実施形態４（図４）に示すように、取付バネ２０，２０の上部を連結部２０ａで連結して一体に構成してもよく、さらに、取付バネ２０，２０のバネ係止片２４の先端部に落下防止爪を設けてもよい。
【００３３】
本実施形態によれば、取付バネ２０を本体１０に取り付けたときに両者の接触面が広くなり、安定かつ確実に固定され、強度が大となる。また、取付バネ２０を係止爪３０ａ，３０ａに沿ってスライドさせ、係止突起部１８に係止孔２３を嵌入するようにしたので、取付バネ２０を本体１０に容易かつ確実に固定することができる。さらに、本体１０の側壁の一部を平面状に切除してバネ取付部１３，１３に平面状の取付背板１６を形成したので、天井等に設ける埋込孔の大きさを最小限にすることができ、取付作業も容易になる。また、取付バネ２０の取付けを差し込み式にしたので、ボツト、ナット等のネジ部品等が不要になり、省部品化、製造の容易化、効率向上が実現できる。
