Description

【０００１】
【産業上の利用分野】
本発明は、例えば照明器具等の天井器具を天井に取付けるための天井器具取付装置およびこの取付装置を用いた天井器具の取付方法に関するものである。
【０００２】
【従来の技術】
図１０は例えば実公平４ー３１６８２号公報に示された従来の天井器具の取付装置を示す断面図、図１１はその取付方法の説明図である。各図において、１は天井器具すなわち照明器具の本体、２は一端が本体１にビス８によって止着された支持ばね、３は支持ばね２の自由端に取付けられた環状のランプ、４は本体１に形成されたつば部、５はつば部４によって支持されるセード、６は本体１の上面中央部に倒伏状態で装着された断面略コ字形のコードガイド具、７はコードガイド具６を覆う筒であり、筒７とコードガイド具６とは共にビス８によって本体１に止着されている。９はコード、１０はコード９を本体１に接続するためのコネクタ、１１はコード９の抜け防止とコードガイド具６からの上方への突出寸法を規定するためのコードストッパ、１２はコード９の上端に接続した引掛プラグ、１３は天井、１４は天井１３に取付けたローゼット、１５はねじりばねのばね線、１６，１７はばね線１５の基部を取付けるためにコードガイド具６の両側に形成した切り起こし爪、１８はばね線１５の巻回部、１９は引掛プラグ１２とローゼット１４とからなる器具取付部を覆う略碗状のカバー、２０はカバー１９の上部内面に形成したブリッジ部で、ブリッジ部２０が形成する穴にばね線１５の自由端が差し込まれている。２１は外向きのつば部２２が付いた短筒で、筒７の上端に嵌着されている。２３はカバー１９の下端部にある内向きのつば部であり、短筒２１のつば部２２に下方から係合し、カバー１９が筒７から抜けるのを防止している。
【０００３】
次に、前述の構成を有する従来装置の天井への取付手順について説明する。まず、図１１に示す如く、カバー１９を下げ、この状態で引掛プラグ１２を手で持って天井１３のローゼット１４に接続する。これにより、本体１が器具取付部にコード９を介して支持される。本体１が器具取付部に支持されると、カバー１９を所定量持ち上げる。カバー１９を所定量持ち上げると、ばね線１５のばね力がカバー１９を天井１３に押し上げる方向に働き、カバー１９を天井１３面に押圧して固定する。
【０００４】
また、器具を取付部から取り外すには、取付けと同様に本体１と天井１３との間に手を差し入れてカバー１９を下げ、この状態で引掛プラグ１２を天井１３のローゼット１４から取り外す。
【０００５】
【発明が解決しようとする課題】
前述のような従来の器具取付構造の場合、本体１と天井１３との間に、器具取付部を覆うカバー１９の取付スペースの他に、器具の取付け、取り外しのための作業空間を確保する必要があり、このため本体１と天井１３面との間の距離、つまり器具の天井１３面から室内への突出量が、器具が取付られた状態にあるときにおいても大きくなって、使用者に圧迫感を与えてしまうという難点があった。
【０００６】
また、カバー１９はつば部２３を介して筒７側の上部に組付けられるようになっているため、使用者から見えるカバー１９の下端と筒７との境目位置に段差ができ、意匠性を損なうという問題点があった。
【０００７】
また、このようなものにおいて、例えばカバー１９、筒７、コードガイド具６を本体１より取り外し、本体１を天井１３面に直接取付けられるようにするためには、本体１の下部より電気的な接続と共に機械的な器具取付を行えるように、天井１３のローゼット１４を露出させる必要がある。このため、本体１の中央部分に大きく穴を開けなければならず、更に本体１の中央部分に穴を開けることにより、本体１内部に収納するスイッチや安定器などを本体１の中央部を避けた周囲部分に配置せざるを得ず、その結果、本体１が大形で高重量化し、取付性が悪くなるという問題点があった。
【０００８】
本発明は叙上の点に鑑み、天井器具の天井面から室内への突出量を小さく抑えることができて、使用者に圧迫感を与えることがなく、またカバー部と器具本体との距離を圧縮できて、使用者からはカバーが器具本体に連続して見え、意匠性が高く、更にスイッチや安定器などを器具本体の中央部に配置できて、器具本体の小形・軽量化が図れる天井器具取付装置およびこの取付装置を用いた天井器具の取付方法を提供することを目的とする。
【０００９】

【００１６】
また、本発明の第８の発明に係る天井器具取付装置は、係止部を、棒状脚部の長手方向にのこ歯状に多段形成したものである。
【００１７】
また、本発明の第９の発明に係る天井器具取付装置を用いた天井器具の取付方法は、天井器具本体との係止部を有し、かつ上部間が連結部によって連結された複数の棒状脚部を備えた取付部材の該脚部を、前記器具本体に貫通させる工程と、前記取付部材の連結部を天井側に固定する工程と、天井器具本体を取付部材の棒状脚部に沿わせて上方にスライドさせる工程と、取付部材の棒状脚部の係止部の上面を天井器具本体側の棒状脚部貫通部と係合させる工程とを有することを特徴としている。
【００１８】
また、本発明の第１０の発明に係る天井器具取付装置を用いた天井器具の取付方法は、天井器具本体の脚部貫通部の近傍に設けた出没自在な動片を付勢手段の付勢力に抗して該脚部貫通部より退出させる工程と、天井器具本体との係止部を有し、かつ上部間が連結部によって連結された複数の棒状脚部を備えた取付部材の該脚部を、前記器具本体の脚部貫通部に貫通させる工程と、動片を解放して付勢手段の付勢力により取付部材の棒状脚部における係止部が形成されている側の面に押し付けさせる工程と、天井器具本体を取付部材の棒状脚部に沿わせて上方にスライドさせることにより、天井器具本体側の動片を該棒状脚部の係止部を乗り越えさせて該係止部の上面と係合させる工程とを有することを特徴としている。
【００１９】
【作用】
本発明の第１の発明においては、天井器具本体と係合してその落下を防止する係止部を有しかつ該器具本体に貫通して該器具本体を上下にスライド可能に案内する複数の棒状脚部を備えた取付部材を介し、器具本体を天井側に取付けるようにしているので、取付けのための作業空間の確保が容易になるとともに、器具が取付けられた状態では、器具本体が上方にスライドされて棒状脚部の係止部に支持されるため、器具本体を天井面に近付けることができ、使用者に圧迫感を与えることがない。また、器具本体の中央部分に穴を開ける必要がないので、本体内部に収納するスイッチや安定器などを本体内の中央部や中央部寄りに配置できるので、その分本体の幅寸法を圧縮でき、本体の小形・軽量化が図れる。
【００２０】
また、本発明の第２の発明においては、取付部材の各棒状脚部を連結する連結部を、天井器具用配線器具に接続される引掛プラグと一体化したので、本体の取付状態が安定する。
【００２１】
また、本発明の第３の発明においては、取付部材の各棒状脚部を連結する連結部を、天井器具用配線器具に接続される引掛プラグのコードと一体化したので、引掛プラグに取付部材を取付けるためのねじ穴等を設ける必要がなく、標準の（市販されている通常の）引掛プラグを用いることができるとともに、器具本体を天井器具用配線器具にある程度回転自在に支持させることができ、天井器具用配線器具を保護することができる。
【００２２】
また、本発明の第４の発明においては、取付部材の各棒状脚部を連結する連結部を、天井器具用配線器具のローゼットが挿通可能な孔を有する板状に形成し、該ローゼット周辺の天井面に直接的に取付けるようにしたので、器具の天井面から室内への突出量をより小さく抑えることができる。
【００２３】
また、本発明の第５の発明においては、取付部材の少なくとも連結部を、ばね性を有する材料から構成して、取付部材の各棒状脚部にばね力を付与することができるようにしたので、このばね力を利用して各棒状脚部の係止部を天井器具本体側の脚部貫通部に係合させることができ、取付け、取り外しのための作業が極めて容易となる。
【００２４】
また、本発明の第６の発明においては、天井器具本体側の脚部貫通部の近傍に、付勢手段により常に棒状脚部の係止部が形成されている側の面に押し付けられて出没自在な動片を設けたので、天井器具取付後に使用者が不用意に棒状脚部の下端部に触れて、棒状脚部を天井器具本体側の脚部貫通部内で撓ませ、あるいは動かしたとしても、この棒状脚部の撓みや動きに動片が追従して動き、常に棒状脚部の係止部との係合状態を保持し、天井器具本体の落下を防止する。これにより、安全性の確保が容易となる。
【００２５】
また、本発明の第７の発明においては、取付部材の棒状脚部に設けた係止部を、棒状脚部に形成した溝内に収容され、かつ背面より付勢手段により付勢されて棒状脚部表面から出没自在に突出する爪から構成したので、取付部材の棒状脚部を天井器具本体側の脚部貫通部に挿通し、そのまま天井器具本体を押し上げるだけで、係止部の爪と天井器具本体側の脚部貫通部とを係合させることができ、更に係止部の爪を棒状脚部の溝内に引っ込めるだけで、係止部の爪と天井器具本体側の脚部貫通部との係合を解くことができる。これにより、取付け、取り外しのための作業が一層容易となる。
【００２６】
また、本発明の第８の発明においては、係止部を、棒状脚部の長手方向にのこ歯状に多段形成したので、天井器具本体の取付位置を調整することができる。これにより、天井器具本体の取付位置を常に高位置に設定できるので、室内への突出寸法の大きいローゼットであっても天井器具本体と天井面との距離を圧縮することができる。
【００２７】
また、本発明の第９の発明においては、天井器具本体との係止部を有し、かつ上部間が連結部によって連結された複数の棒状脚部を備えた取付部材の該脚部を、前記器具本体に貫通させ、前記取付部材の連結部を天井側に固定した後、天井器具本体を取付部材の棒状脚部に沿わせて上方にスライドさせて、取付部材の棒状脚部の係止部の上面と天井器具本体側の棒状脚部貫通部とを係合させるようにしたので、取付け作業の効率化が図れる。
【００２８】
また、本発明の第１０の発明においては、天井器具本体の脚部貫通部の近傍に設けた出没自在な動片を付勢手段の付勢力に抗して該脚部貫通部より退出させた状態で、天井器具本体との係止部を有し、かつ上部間が連結部によって連結された複数の棒状脚部を備えた取付部材の該脚部を、天井器具本体の脚部貫通部に貫通させてから、動片を解放して付勢手段の付勢力により取付部材の棒状脚部における係止部が形成されている側の面に押し付けさせた後、天井器具本体を取付部材の棒状脚部に沿わせて上方にスライドさせることにより、天井器具本体側の動片を該棒状脚部の係止部を乗り越えさせて該係止部の上面と係合させるようにしたので、取付け作業の効率化が図れ、かつ取付け後の安全性の確保が容易となる。
【００２９】
【実施例】
実施例１．
以下、図示実施例により本発明を説明する。
図１は本発明の第１の実施例に係る天井器具取付装置の一部を破砕して示す構成図、図２はその要部を拡大して示す斜視図、図３はその取付方法の説明図であり、各図中、従来に相当する部分には同一符号を付しその説明を省略する。また、ここでは天井器具として照明器具を例に挙げて説明する。各図において、２４はスイッチ、２５は安定器であり、これらは照明器具の本体１内の中央部や中央部寄りに配置されて収納されている。コード９の途中に固定されたコードストッパ１１は、本体１からのコード９の抜け防止を行う。略碗状のカバー１９は、本体１の上部に取付けられた押上ばね２６のばね力によって常に天井１３方向に押し上げられ、コード９の上端に接続した引掛プラグ１２と天井１３に取付けたローゼット１４とからなる器具取付部２７を覆うようになっている。また押上ばね２６は、カバー１９との係合状態を保持したままカバー１９を所定量上方向に付勢できるように設定されている。２８は本体１を上下方向にスライド可能に保持するコ字状に形成された取付部材である。
【００３０】
取付部材２８は、棒状の両脚部２９，３０と、両脚部２９，３０の上端間を連結する連結部３１と、両脚部２９，３０の長手方向の中間部にそれぞれ外方に突出形成した係止部３２，３３と、両脚部２９，３０の下端にそれぞれ取付けたストッパ３４，３５とから成り、かつ連結部３１はビス８によって引掛プラグ１２と一体化されている。また、両脚部２９，３０は、いずれも本体１の上部に設けた各挿通穴３６と本体１の下部に設けた各係止穴３７とを貫通し、それぞれが本体１を上下方向に案内するようになっている。本体１上部の各挿通穴３６は、それぞれ両脚部２９，３０の係止部３２，３３が挿通可能な幅を有する長穴に形成され、また本体１下部の各係止穴３７は、図２に示す如く、それぞれ両脚部２９，３０の係止部３２，３３が挿通可能な幅を有する第１の穴３７ａと、係止部３２，３３と係合可能な小幅に設定されて第１の穴３７ａに連続する第２の穴３７ｂとから形成されている。更にストッパ３４，３５は、それぞれ第１の穴３７ａ（あるいは挿通穴３６）よりも大きい寸法に設定されており、第１の穴３７ａ（又は第２の穴３７ｂ）と係合することにより本体１の落下を防止するようになっている。なお、ストッパ３４，３５は、両脚部２９，３０を本体１の挿通穴３６と係止穴３７とを貫通させた後に、両脚部２９，３０の下端に取付けられることは言うまでもない。
【００３１】
次に、前述の構成を有する本実施例の天井器具取付装置を用いた天井器具の取付方法について、図１乃至図３に基づき説明する。まず、図３に示す如く、本体１を取付部材２８の両脚部２９，３０下端のストッパ３４，３５に乗せた状態で、カバー１９を本体１上部の押上ばね２６の自由端に乗せる。この状態では、本体１は取付部材２８の両脚部２９，３０の下端にあるため、引掛プラグ１２と本体１との間にはカバー１９と手の入る充分なスペースが発生している。次いで、引掛プラグ１２を手で持って天井１３のローゼット１４に接続する。この状態では、本体１が器具取付部２７に取付部材２８のストッパ３４，３５を介して支持されている。次に、本体１を両脚部２９，３０に沿わせて下側から押し上げ、両脚部２９，３０の係止部３２，３３を、本体上部の各挿通穴３６と本体下部の各係止穴３７の第１の穴３７ａとを貫通させた後、本体１を取付部材２８に対し下面側から見て時計方向に相対回動させて、係止部３２，３３と各係止穴３７の第２の穴３７ｂとを、図１に示す如く、それぞれ係合させる。これにより、本体１が器具取付部２７に取付部材２８の係止部３２，３３を介して支持されるとともに、カバー１９が押上ばね２６のばね力により天井１３面に押圧されて密着する。
【００３２】
また、器具を器具取付部２７から取り外すには、前述の取付けと逆の手順により引掛プラグ１２を天井１３のローゼット１４から取り外す。即ち、まず本体１を取付部材２８に対し下面側から見て反時計方向に相対回動させて、係止部３２，３３と各係止穴３７の第１の穴３７ａとの位置合わせを行った後、本体１を持ち下げて取付部材２８の両脚部２９，３０下端のストッパ３４，３５に乗せる。次いで、引掛プラグ１２を天井１３のローゼット１４から取り外す。
【００３３】
このように、本実施例においては、器具の引掛プラグ１２を天井１３のローゼット１４に取付け、あるいは引掛プラグ１２をローゼット１４から取り外す際、本体１を取付部材２８の両脚部２９，３０下端のストッパ３４，３５に乗せた状態で作業を行うので、取付け、取り外しのための作業空間を大きく確保できるとともに、器具が取付けられた状態では、本体１が取付部材２８の係止部３２，３３に支持されて高い位置に配置されるので、カバー１９と本体１との距離が圧縮されて、使用者からはカバー１９が本体１に連続して見え、意匠性を損なうことがなく、更に器具の天井１３面から室内への突出量も小さく抑えられ、使用者に圧迫感を与えることがない。
【００３４】
また、本体１内に収納するスイッチ２４や安定器２５を、本体１内の中央部や中央部寄りに配置できるので、その分本体１の幅寸法を圧縮でき、本体の小形・軽量化が図れる。
【００３５】
また、取付部材２８の連結部３１と引掛プラグ１２とをビス８によって一体化しているので、本体１の取付状態が安定する。
【００３６】
実施例２．
図４は本発明の第２の実施例に係る天井器具取付装置の要部を拡大して示す正面図であり、実施例１と同一部分には同一符号を付してある。また、ここでは図１を参照しながら説明する。この実施例の天井器具取付装置は、本体１を上下方向にスライド可能に保持するコ字状に形成された取付部材２８の連結部３１を、コード９の上端部、つまりコード９における引掛プラグ１２近傍に取付けたものであり、それ以外の構成は前述の実施例１と同様である。
【００３７】
この実施例においては、取付部材２８をコード９を介して引掛プラグ１２側に取付けるようにしているので、引掛プラグ１２に取付部材２８を取付けるためのねじ穴等を設ける必要がなく、標準の（市販されている通常の）引掛プラグ１２を用いることができる利点を有している。
【００３８】
また、取付部材２８を引掛プラグ１２側にコード９を介して取付けたことにより、本体１を器具取付部２７にある程度回転自在に支持させることができるため、使用者が誤って本体１を長穴（各挿通穴３６と各係止穴３７）の範囲内を越えて回した場合でも、器具取付部２７に力が加わることがなく、器具取付部２７を保護することができる。
【００３９】
なお、この実施例の利点である器具取付部保護機能の観点からみれば、取付部材２８と引掛プラグ１２とは、コード９の挿通穴を有するトラニオンホルダ等を介して相対回転自在に組付けるようにしてもよく、この場合には器具取付部保護機能を更に向上させることができるとともに、コード９の保護機能をも高めることができる。
【００４０】
実施例３．
図５は本発明の第３の実施例に係る天井器具取付装置の要部を拡大して示す断面図であり、実施例１に相当する部分には同一符号を付してある。この実施例の天井器具取付装置は、天井１３に木ねじ３８で取付金具３９を取付け、取付金具３９につまみねじ４０で取付部材２８を取付けるようにしたものである。
【００４１】
これを更に詳述すると、取付金具３９は、底部中央に天井１３のローゼット１４が挿通可能な孔４１を有する皿状に形成され、その底部が天井１３面に接した状態で木ねじ３８により固定されている。
【００４２】
また、取付部材２８は、下部に外向きの係止部３２，３３を有する棒状の両脚部２９，３０と、両脚部２９，３０の上端間を連結するとともに、中央部にローゼット１４が挿通可能な孔４２を有し、かつ周縁に固定用のつば部４３が設けられた板状の連結部４４とから形成され、つば部４３が取付金具３９のつば部４５に接した状態でつまみねじ４０により固定されている。
【００４３】
また、本体１には、その上面中央に引掛プラグ１２とローゼット１４とからなる器具取付部２７を収容できる凹部４６が設けられており、器具が取付けられた状態では、本体１の凹部４６周辺の上面が天井１３面に接した状態で、その各係止穴３７の第２の穴３７ｂ（図２参照）が取付部材２８の係止部３２，３３と係合して支持されるようになっている。それ以外の構成は前述の実施例１と同様である。
【００４４】
この実施例の天井器具取付装置を用いて天井器具を取付けるには、まず取付金具３９をその孔４１に天井１３のローゼット１４を挿通させた状態で木ねじ３８により天井１３に固定する。次に、取付部材２８の連結部４４の孔４２にローゼット１４を挿通させた状態で、そのつば部４３と取付金具３９のつば部４５の位置合わせを行い、これらをつまみねじ４０により一体化する。次いで、本体１と共に引掛プラグ１２を手で持ってローゼット１４に接続する。次いで、本体上部の各挿通穴３６と取付部材２８の両脚部２９，３０の位置合わせを行い、本体１を両脚部２９，３０に沿わせて下側から押し上げて、両脚部２９，３０の係止部３２，３３を、各挿通穴３６と本体下部の各係止穴３７の第１の穴３７ａ（図２参照）とを貫通させ、かつその凹部４６内に器具取付部２７を収容させた後、本体１を取付部材２８に対し下面側から見て時計方向に相対回動させて、係止部３２，３３と各係止穴３７の第２の穴３７ｂ（図２参照）とを、図５に示す如く、それぞれ係合させる。これにより、本体１はその凹部４６周辺の上面が天井１３面に接した状態で、取付金具３９に取付部材２８を介して支持される。
【００４５】
また、器具を器具取付部２７から取り外すには、まず本体１を取付部材２８に対し下面側から見て反時計方向に相対回動させて、係止部３２，３３と各係止穴３７の第１の穴３７ａとの位置合わせを行った後、持ち下げて取付部材２８の両脚部２９，３０から引き抜き、次いで引掛プラグ１２を天井１３のローゼット１４から取り外す。
【００４６】
この実施例においては、取付部材２８を天井１３に直接的に取付けるようにしたので、器具の天井１３面から室内への突出量をより小さく抑えることができる。
【００４７】
また、本体１の上面中央に器具取付部２７を収容できる凹部４６を設け、本体１の凹部４６周辺の上面を天井１３面に接した状態で器具が取付けられるようにしたので、器具取付部２７の天井１３面から室内への突出が実質的になくなって、意匠的に斬新なものが得られる。
【００４８】
また、取付部材２８を皿状の取付金具３９を介して天井１３に取付けるようにしたので、取付部材２８の製作誤差を取付金具３９が備えているばね機能で吸収することができる。
【００４９】
実施例４．
図６は本発明の第４の実施例に係る天井器具取付装置の要部を拡大して一部を破砕して示す断面図であり、実施例１に相当する部分には同一符号を付してある。この実施例の天井器具取付装置は、取付部材２８を、開口部を広げた略コ字状のばね性のある線材４７と、下端が先細り状に傾斜した略直角三角形に形成された外向きの係止部３２，３３を有し、かつ線材４７の両脚部４８，４９にそれぞれ外嵌状態に一体的に成形した樹脂性のガイド棒５０，５１と、線材４７における両脚部４８，４９を連結する連結部５２の中央部に外嵌状態に一体的に成形した樹脂性の取付部５３とから構成している。
【００５０】
また、本体１には、その上部に挿通穴５４が、その下部に係止穴５５が、それぞれ設けられている。各挿通穴５４と各係止穴５５は、いずれもガイド棒５０，５１の係止部３２，３３が挿通できる程度の大きさに形成され、かつ各係止穴５５はその位置が各挿通穴５４よりも本体１中心寄りに設定されている。このため、各係止穴５５は、その外側エッジで線材４７のばね力を常に受けるようになっている。それ以外の構成は前述の実施例１と同様である。
【００５１】
この実施例の天井器具取付装置を用いて天井器具を取付けるには、まずガイド棒５０，５１の上端部を手で挾んでその下端部を線材４７のばね力に抗して若干閉じさせた状態で、本体１の各挿通穴５４と各係止穴５５に挿通し、この状態で引掛プラグを天井のローゼットに接続した後、本体１を押し上げる。本体１が押し上げられると、各係止穴５５の外側エッジは、係止部３２，３３の傾斜面を乗り越え、係止部３２，３３の上面と係合する。これにより、本体１は器具取付部に取付部材２８のガイド棒５０，５１の係止部３２，３３を介して支持される。
【００５２】
また、器具を器具取付部２７から取り外すには、ガイド棒５０，５１の下端部を手で挾んで線材４７のばね力に抗して閉じ、各係止穴５５とガイド棒５０，５１の係止部３２，３３との係合を解く。これにより、本体１をガイド棒５０，５１から引き抜くことができ、引掛プラグを天井のローゼットから取り外すことができる。
【００５３】
この実施例においては、本体１にガイド棒５０，５１を挿通した状態で引掛プラグを天井のローゼットに接続し、本体１を押し上げるだけで取付けが完了し、またガイド棒５０，５１の下端部を線材４７のばね力に抗して閉じるだけで本体１をガイド棒５０，５１から引き抜くことができ、引掛プラグを天井のローゼットから取り外すことができるので、取付け、取り外しのための作業が極めて容易となる。
【００５４】
実施例５．
