Description

【０００１】
【発明の属する技術分野】
本発明は、主に天井に換気や空調に用いられるダクト用換気扇やグリルなどの機器を取り付ける場合の取付装置及び取付方法に関する。
【０００２】
【従来の技術】
従来から、取付ねじを用いた機器の取付装置が種々提案されている。例えば、本体枠の外周に設けた凹状の溝部の内を支点にした一対の支持手段により起立状態または横伏せ状態に傾倒自在に支持される取付金具を取付ボルトにより可動としている取付装置が知られている（例えば、特許文献１参照）。
【０００３】
このような機器の取付装置においては、取付ボルトを締め付けることにより支持手段に支持された一対の取付金具の先端が横伏せ状態となり、本体枠に設けたフランジ部と取付金具の先端との間で天井板を挟み込んで２点固定により本体枠を固定している。
【０００４】
【特許文献１】
特開平８−２５４３４１号公報（第３頁、図１）
【０００５】
【発明が解決しようとする課題】
しかしながら、このような特許文献１記載の機器の取付装置では、取付金具の先端は支持手段を支点として回動して天井板に押し当てられるので、天井板と取付金具の先端との接点は点または線での当接となり、ドライバーなどを用いて強く取付金具を取り付けた場合には、取付金具の先端が天井板内に潜り込み天井板が破損する恐れがあった。また、２点固定の線接触による挟持のため保持力が不十分であった。
【０００６】
本発明は上記課題を解決するもので、強く固定しても天井板の取付け面が破損しにくい機器の取付装置及び取付方法を提供することを目的とする。
【０００７】
【課題を解決するための手段】
第１の発明は、取付面材の表面に固定するためのフランジ部とダクト連設部を備えた本体枠と、該本体枠を挿嵌するためのダクト用開口を備え前記フランジ部と共に前記取付面材を挟持して前記本体枠を前記取付面材に固定する取付具と、から構成され、前記取付具は取付面材に形成された取付開口から挿入できる平板部材であり、中央に本体枠を挿嵌するためのダクト用開口を備えることによりその周囲に前記フランジ部と共に取付面を挟持して支持する面状支持部を備え、該面状支持部は、前記取付開口の内周に対応する大きさに前記面状支持部から立設又は曲折された複数の位置決め爪を備えると共に、前記取付開口の内周側に位置する部位に穿設された固定用螺孔と、前記取付開口の外周側に位置する部位に穿設された前記取付具を前記取付面材に仮固定するための仮止め用螺孔とを備え、前記フランジ部は、前記固定用螺孔に対応する位置に穿設されたねじ固定用孔を備え、前記取付具に設けられた固定用螺孔は、前記本体枠に設けられた固定用孔とともに前記取付面材を前記フランジ部と前記取付具とで挟持して前記本体枠を取付面材に取付固定することを特徴とする機器の取付装置である。
【０００８】
このように構成すれば、取付面材に形成された取付開口より平面部材である取付具を挿嵌させて取付面材の裏面に取付具を位置決めしつつ仮固定することができる。ついで、取付具に備えられたダクト用開口から（機器の）本体枠を挿嵌させることにより、ダクト用開口の周囲に形成された面状支持部と本体枠のフランジ部とで取付面材を面接触させて機器を取付面材に固定することができる。
これにより、機器を強く固定しても、天井板等の取付面材が破損しにくい機器の取付装置を提供することができる。
【０００９】
また、第２の発明の機器の取付装置は、取付面材の表面に固定するためのフランジ部とダクト連設部を備えた本体枠と、該本体枠を挿嵌するためのダクト用開口を備え前記フランジ部と共に前記取付面材を挟持して前記本体枠を前記取付面材に固定する取付具と、から大略構成され、前記取付具は取付面材に形成された取付開口から挿入できる平面視縦長の長さの異なる平板部材であり、中央に本体枠を挿嵌するためのダクト用開口を備えることによりその周囲に前記フランジ部と共に取付面を挟持して支持する面状支持部を備え、該面状支持部は、前記取付開口の内周に対応する大きさに前記面状支持部から立設又は曲折された複数の位置決め爪を備えると共に、前記取付開口の内周側に位置する部位の長手方向に沿った中央位置であって前記開口の中心に対して対称位置に穿設された一対の固定用螺孔と、前記取付開口の外周側に位置する部位の長手方向に沿って前記開口の中心に対して対称位置であって長手方向からずれた位置に穿設された前記取付具を前記取付面材に仮固定するための一対の仮止め用螺孔と、該仮止め用螺孔に対して短辺方向に対称位置に穿設された一対の位置決め孔を備え、前記フランジ部は前記取付開口よりも内周側に形成された段落部と該段落部の外周であって前記取付開口よりも外周側に前記段落部とは階段状に形成された前記取付面材を挟持する挟持部とを備え、前記段落部は、前記固定用螺孔に対応する位置に穿設されたねじ固定用孔を備え、前記取付具に設けられた固定用螺孔は、前記本体枠に設けられた固定用孔とともに前記取付面材を前記挟持部と前記取付具とで挟持して前記本体枠を取付面材に取付固定することを特徴とする。
【００１０】
また、本発明の機器の取付方法は、上記の機器の取付装置を用い、取付面材の所定位置に位置決め爪の位置に対応する大きさの取付開口を切り開く取付開口の開口工程、前記取付面材の表面側から前記位置決め爪を前記取付開口の内周に挿嵌しつつ取付具の位置決めをした状態で、前記位置決め孔を利用して前記取付面材に仮止めねじ貫通用の仮止用貫通孔を穿設する貫通孔の穿設工程、前記取付開口から取付面材の裏面に取付具を挿嵌させ、位置決め爪を前記取付開口の内周に挿嵌しつつ前記仮止用貫通孔の位置を前記仮止め用螺孔に位置合わせを行い、仮止め用部材で前記取付面材の裏面に前記取付具を位置決めして固定する取付面材の仮止め工程、前記ダクト用開口から本体枠を挿嵌してねじ固定用孔を固定用螺孔に位置合わせを行い、表面側から固定用螺孔に螺合するねじにより螺合することにより、前記取付面材を前記フランジ部と前記取付具とで挟持して前記本体枠を前記取付面材に取付固定する取付固定工程とを順次行うことを特徴とする。
【００１１】
このように構成すれば、取付面材の所定位置に位置決め爪の位置に対応する大きさの取付開口を切り開き、ついで、取付面材の表面側から位置決め爪を取付開口の内周に挿嵌しつつ取付具の位置決めをし、位置決め孔を利用して取付面材に、例えば、ドリルなどにより穿設して仮止め用の貫通孔を穿設し、ついで、取付開口から取付面材の裏面に取付具を挿嵌させ、裏面側から位置決め爪を取付開口の内周に挿嵌しつつ穿設された仮止用貫通孔の位置を仮止め用螺孔に位置合わせを行い、仮止め用部材で仮固定すれば、取付面材の裏面に取付具が位置決めされて仮り固定される。ついで、ダクト用開口から本体枠のダクト連設部を挿嵌してねじ固定用孔を固定用螺孔に位置合わせを行い、表面側から固定用螺孔に螺合するねじにより螺合することにより、取付面材をフランジ部と取付具とで挟持して本体枠を取付面材に取付固定することができる。
【００１２】
この取付具と取付面材との当接は面接触であるので、取付ねじを強く螺合させる等して取付面材に機器を固定しても、取付具が取付面材に潜り込むことがない。これにより、強くねじ込んでも天井板の取付け面が破損しにくい機器の取付装置及び取付方法を提供することができる。
【００１３】
【発明の実施の形態】
以下、本発明の実施の形態を図１〜図９を参照しつつ説明する。
【００１４】
本発明の機器の取付装置１は、取り付けるべき所定箇所に取付開口２が開口された取付面材３の表面に固定するためのフランジ部４と不図示のダクトに連設するダクト連設部５を備えた本体枠６と、フランジ部４と共に取付面材３を挟持して本体枠６を取付面材３に固定する取付金具（取付具）７とから大略構成されている。
【００１５】
この取付金具７は、図５，６に示すように、取付開口２から挿入できる平面視縦長の長さの異なるプレートから大略構成され、中央に本体枠６を挿嵌するための大きなダクト用開口８を備えている。これにより、このダクト用開口８の周囲にフランジ部４と共に取付面材３を挟持して支持する面状支持部９が形成されている。
【００１６】
この面状支持部９には、取付開口２の内周に対応する位置に複数（図では４個）の位置決め爪１０…が裏面９ｂ側に向けて立設又は曲折され（図では曲折）、また、この位置決め爪１０が立設又は曲折される面とは反対側（表面９ａ側）に向けてダクト用開口８の内周に一対の補強リブ１１、１１が曲折され、また、長辺側の外側に沿って一対の補強リブ１２、１２が曲折されて設けられている。
【００１７】
また、この面状支持部９には、固定用螺孔１３及び仮止め用螺孔１４とこの仮止め用螺孔１４に対して短辺方向に対称位置に大きめに穿設された一対の位置決め孔１５が設けられている。
【００１８】
固定用螺孔１３は、取付開口２の内周側に位置する部位の長手方向に沿った中央位置であって取付開口２の中心に対して対称位置に一対穿設され、また、仮止め用螺孔１４または位置決め孔１５は、取付開口２の外周側に位置する部位の長手方向に沿って取付開口２の中心に対して対称位置であって長手方向からそれぞれ短辺方向に対称位置に穿設されている。
【００１９】
また、フランジ部４は取付開口２よりも内周側に形成された段落部１６と取付開口２よりも外周側に段落部１６とは階段状に形成された取付面材３を挟持する挟持部１７とから形成されている。この段落部１６には、固定用螺孔１３に対応する位置にねじ固定用孔１８が穿設されている。また、挟持部１７には表面側に向けて窪んだ環状凹部１７ａを備えている。この環状凹部１７ａは、挟持部１７に凹凸を持たせることにより挟持部１７の強度を持たせる為と、後述する仮止め用ねじ（仮止め用部材）２０の頭部２０ａと挟持部１７とが干渉しないようにするためのものであるので、その形状は自由である。例えば、後述のルーバの外形に沿った平面視方形であってもよく、また、円形であってもよい。また、挟持部の強度が小さくてよい場合には、環状ではなく頭部２０ａに干渉しない程度の局部的な凹部であってもよい。
【００２０】
以上のように構成された機器の取付装置１を用いれば、取付面材３の所定位置に位置決め爪１０の位置に対応する大きさの取付開口２を切り開く。ここでこの取付開口２は、あらかじめ開口された取付面材３を用いてもよく、また、取り付けられた状態で表面側から切り開いてもよい。
【００２１】
ついで、取付面材３の表面３ａに取付金具７の表面７ａを向けて、取付面材３の表面３ａ側から位置決め爪１０を取付開口２の内周に挿嵌しつつ取付金具７の位置決めを行う。
【００２２】
ついで、位置決め孔１５を利用して、例えば、ドリルなどにより取付面材３を穿設して仮止め用の貫通孔１９を穿設する。
【００２３】
ついで、取付開口２から裏面３ｂ側に取付金具７を挿嵌させ、取付面材（取付け部：天井面）３の裏面３ｂに取付金具（取付具）７の表面７ａを向けて、取付面材３の裏面３ｂ側から位置決め爪１０を取付開口２の内周に挿嵌しつつ穿設された仮止用貫通孔１９の位置を仮止め用螺孔１４に位置合わせを行う。この状態で、仮止め用ねじ２０を取り付ければ、取付面材３の裏面３ｂに取付金具７が位置決めされて仮り固定される。この仮止め用ねじ２０の尾部２０ｂは取付面材３の裏面３ｂに突出することになるが、屋内側から視認できないのでこのままでよい。
【００２４】
このように、本願発明においては、仮止め用螺孔１４の位置と位置決め孔１５の位置とを短辺方向に対して対称に設けることにより、取付金具７を取付面材３に対して表裏を反転して当接させた状態で、位置決め孔１５の位置が仮止め用螺孔１４の位置に位置決めできる。それ故、この発明の実施の形態では、取付金具７の位置決め爪１０補強リブ１１，１２などのその他の部位部材も対称に設けられているが、必ずしもこれらの部位部材は対称である必要はない。
【００２５】
また、この位置決め用孔１５は、ドリルなどを用いて取付面材３に貫通孔１９を形成するので、図示の通り、仮止め用螺孔１４比べて開口径が大きい方がよい。
【００２６】
ついで、ダクト用開口８から本体枠６のダクト連設部５を挿嵌してねじ固定用孔１８を固定用螺孔１３に位置合わせを行い、表面側３ａから固定用螺孔１３に螺合する固定ねじ（固定具）２１により螺合することにより、取付面材３をフランジ部４と取付金具７の面状支持部９とで挟持して本体枠６を取付面材３に取付固定することができる。固定ねじ２１の頭部２１ａはこの時点では露出するが、グリル２２等を表面側からかぶせることにより、室内側から視認されることはない。
【００２７】
この取付金具７と取付面材３との当接面（表面３ａ）は広い面積で当接するので、固定ねじ２１を強く螺合させても、取付金具７が取付面材３に潜り込むことがない。これにより、強くねじ込んでも取付面材として石膏ボードなどを用いても、取付面が破損しにくい機器の取付装置１及び取付方法を提供することができる。
【００２８】
取付金具７は、位置決め機能、仮止め機能、固定機能と複数の機能を有していることにより、部品点数を増やすことなく、機器を簡単に取り付けることができる。
【００２９】
以上、この発明の実施の形態を図面により詳述してきたが、具体的な構成はこの実施の形態に限らず、この発明の要旨を逸脱しない範囲の設計の変更等があってもこの発明に含まれる。
【００３０】
例えば、以上の発明の実施の形態では取付ねじは取付金具に穿設されたねじ溝に螺合していたが、取付金具に裏ナットなどを適宜固着していてもよい。
【００３１】
【発明の効果】
以上説明したように、本発明に従えば、取付具が取付面に潜り込むことがない。これにより、固定用のねじ等の固定具により強く固定しても天井板の取付け面が破損しにくい機器の取付装置及び取付方法を提供することができる。
