Description

【0001】
【発明の属する技術分野】
本発明は、ドアを開口枠に回動自在に取付けることができると共に、その開口枠を柱等の躯体に取付けることのできるドア取付け金具に関するものである。
【0002】
【従来の技術】
一般の建物においては、図1および図10に示すように、ドア20は蝶番Cによって開口枠10に回動自在に取付けられ、また、この開口枠10は柱等の躯体70に別の固定金具Kで取付けられている。従って、ドア20は、実質的に開口枠10によって支持されている。
【0003】
通常、ドア20の重量は中空のいわゆるフラッシュ構造でも15kg程度であり、無垢の木材を使用した高級品では40kg程度もある。従って、毎日の開閉や、建物の歪み、あるいはドア20や開口枠10を取付けるネジの緩み等によって、ドア20と開口枠10あるいは開口枠10と躯体70との間の間隔が変化し、ドア取付け後、数年程度でドア20が開口枠10に接触する等の不具合が発生し易い。
【0004】
その原因が単なるネジの緩みであれば、そのネジを締め直して対処することができるが、それ以外の蝶番Cや固定金具K自体による場合には修正が困難である。かつては、ドア20の接触する部分を鉋等で削り落としたり、蝶番Cの取付け位置を微妙にずらすなどの面倒な調整に頼っていた。
【0005】
こうした点に鑑み、近年では、蝶番Cに調整機構を組み込んで、ドア20の取付け位置を修正できるようにしたものが開発され、広く使用されるようになってきた。
例えば、本出願人が先に出願した蝶番(特開2001−220938)は、ドアを上下、左右および前後の三方向に移動させて微調整することができる。
【0006】
一方、開口枠10と躯体70との位置調整に関しても、両者の間隔を調整できる固定金具が開発され、使用されるようになっている(例えば、特許第2929002号や特許第2966792号に開示の調整金具)。
【0007】
【発明が解決しようとする課題】
しかしながら、こうした従来のドア取付構造には、次のような問題点がある。
(1)蝶番と固定金具といった二つの別個の部材を必要とするため、取付けが厄介で、その取り扱い(搬送など)も面倒である。
(2)構造が複雑で、調整部分が多いため、調整が厄介である。
ドアを開口枠に取付けるための蝶番と、開口枠を躯体に取付けるための固定金具をそれぞれ別々に取付け、かつそれぞれの調整機構を別々に調整する必要があるため、ドアの建付け調整に多くの時間を要する。すなわち、ドアの建付け時に、まず枠体を固定金具で躯体に取付けてその位置を固定金具の調整機構によって微調整した後、その枠体に蝶番でドアを取付けた後、その蝶番の調整機構によってドアの位置を微調整する必要がある。このとき、蝶番の調整機構によってドアを適正位置に取付けることができない場合は、一旦、ドアを開口枠から取り外して開口枠の躯体に対する位置関係を再度調整し、再びドアを取付ける必要があるなど、調整が厄介となる。
(3)ネジが緩み易く、ドアの取付け姿勢が不安定となり易い。
調整部分が多く、多数のネジを使用しているので、その分、ネジの緩みが発生し易い。特に、ドアを開口枠へ取付ける蝶番は木ねじを使用して行っているので、長期間の開閉による振動により、緩みが発生し易く、その結果、時間の経過と共にドアが傾く等の弊害が発生し易い。
(4)開口枠に高い強度が要求され、高価となる。
開口枠は固定金具によって躯体に取付けられ、また、この開口枠には蝶番によってドアが取付けられるので、これらの取付け姿勢を安定に保つために、開口枠には高い強度が要求される。従って、開口枠は肉厚で重い合板等を使用せざるを得ず、価格も高価となってしまう。
(5)ドア開口部が狭くなる。
開口枠は、高い強度が要求されるために肉厚となり、従って、ドア開口部の幅や高さがそれだけ狭くなってしまう。
【0008】
そこで、本発明の目的とするところは、ドア等の取付けやそれ自体の取り扱いが容易で、構造が簡単で調整が容易であり、ドアの取付け姿勢が長期にわたって安定し、開口枠を廉価することができ、ドア開口部を狭くすることのないドア取付け金具を提供することにある。
【0009】
【課題を解決するための手段】
上記の目的を達するために、請求項1に記載の発明は、後端部同士がヒンジ結合された第一プレート(31)と第二プレート(32)の先端部にそれぞれ結合された、開口枠(10)に取付けられる枠側ベース部材(41)と、ドア(20)端部に取付けられるドア側ベース部材(42)とを備え、開口枠(10)にドア(20)を回動自在に取付けると共に、前記開口枠(10)を柱等の躯体(70)に取付ける金具であって、前記枠側ベース部材(41)に、開口枠(10)を貫通し、内周面に雌ネジを有する雌ネジ部(41b)が設けられ、当該雌ネジ部(41b)には、開口枠(10)側である一方端部にレンチ孔(60b)を有するとともに外周面に雄ネジを有する雄ネジ部材(60)が螺合され、当該雄ネジ部材(60)の躯体(70)側には、躯体(70)に当接し、雄ネジ部材(60)の他方端部と回転自在かつ抜け出し不能に組付く受け部材(61)が設けられ、雄ネジ部材(60)と受け部材(61)の中央部には、ネジ孔(60a,61a)が形成されていることを特徴とする。
【0010】
また、請求項2に記載の発明は、後端部同士がヒンジ結合された第一プレート(31)と第二プレート(32)の先端部にそれぞれ結合された、開口枠(10)に取付けられる枠側ベース部材(41)と、ドア(20)端部に取付けられるドア側ベース部材(42)とを備え、開口枠(10)にドア(20)を回動自在に取付けると共に、前記開口枠(10)を柱等の躯体(70)に取付ける金具であって、前記第二プレート(32)は、ドア側ベース部材(42)に対して分離可能であり、ドア側ベース部材(42)は、ドア(20)の厚み方向に左右対称の形状で、ドア(20)から突出することなくドア(20)端部に埋設され、しかもドア側ベース部材(42)にはドア(20)の厚み方向に貫通し、第二プレート(32)の先端部をドア(20)の表側からも裏側からも差込み案内可能なスリット(44)が形成されるとともに、スリット(44)に案内された第二プレート(32)を係止するロック機構が設けられ、前記枠側ベース部材(41)に、開口枠(10)を貫通し、内周面に雌ネジを有する雌ネジ部(41b)が設けられ、当該雌ネジ部(41b)には、開口枠(10)側である一方端部にレンチ孔(60b)を有するとともに外周面に雄ネジを有する雄ネジ部材(60)が螺合され、当該雄ネジ部材(60)の躯体(70)側には、躯体(70)に当接し、雄ネジ部材(60)の他方端部と回転自在かつ抜け出し不能に組付く受け部材(61)が設けられ、雄ネジ部材(60)と受け部材(61)の中央部には、ネジ孔(60a,61a)が形成されていることを特徴とする。
【0011】
さらに、請求項3に記載の発明は、請求項2に記載の発明において、第二プレート(32)の後端部は、第一プレート(31)の後端部に対して調整螺子(36,37)により上下方向に移動自在に結合され、しかも第一プレート(31)の先端部は、枠側ベース部材(41)に形成された第一プレート(31)の板厚よりも幅広の長孔(43)に挿入され調整螺子(47,49)により長孔(43)内で第一プレート(31)の厚み方向に移動自在に結合されるとともに、第一プレート(31)の先端部は、枠側ベース部材(41)に対して調整螺子又は調整カム(45)により接離調整自在に結合されていることを特徴とする。
【0012】
またさらに、請求項4に記載の発明は、請求項2または3に記載の発明において、第二プレート(32)の先端部中央には孔(34)が設けられ、ロック機構は、第二プレート(32)に当接する間は収縮するが孔(34)の位置に達すると伸長して孔(34)を係止する弾性突部(51,52)からなり、伸長した弾性突部(51,52)を収縮させて係止を解除可能にしたことを特徴とする。
【0013】
なお、上記の課題を解決するための手段に記載された括弧内の記号は図面及び後述する発明の実施の形態に記載された記号に対応するものである。
【0014】
請求項1に記載の発明によれば、ヒンジ結合された第一プレートと第二プレートの先端部に、開口枠に取付けられる枠側ベース部材と、ドア端部に取付けられるドア側ベース部材とを備えているので、ドアを開口枠に回動自在に取付けることができる。
【0015】
また、枠側ベース部材に、開口枠を貫通し、内周面に雌ネジを有する雌ネジ部が設けられ、その雌ネジ部には、開口枠側である一方端部に六角孔を有するとともに外周面に雄ネジを有する雄ネジ部材が螺合され、雄ネジ部材の躯体側には、躯体に当接し、雄ネジ部材の他方端部と回転自在かつ抜け出し不能に組付く受け部材が設けられ、さらに、雄ネジ部材と受け部材の中央部には、ネジ孔が形成されているので、開口枠を柱等の躯体に取付けることができる。
【0016】
すなわち、請求項1に記載の発明に係るドア取付け金具は、それのみ(単体)によってドアを開口枠に取付けることができると共に、その開口枠を躯体に取付けることができるので、以下の作用効果を発揮する。
【0017】
(1)ドア取付け金具のみで、ドアと開口枠の取付けができるので、従来と比較して部品点数を減らすことができる。それにより、ドアおよび開口枠の取付け作業が容易であり、また、その部品自体の取り扱いも容易である。
(2)構造が簡単で、調整部材が少ないため、調整が容易である。
従来のように、ドアを開口枠に取付けるための蝶番と、開口枠を躯体に取付けるための固定金具をそれぞれ別々に取付け、かつそれぞれの調整機構を別々に調整する必要がないため、ドアの建付け調整が容易である。
(3)ネジが緩み難く、ドアの取付け姿勢が安定する。
調整部分が少なく、ネジの数も少ないので、その分、ネジの緩みが発生し難い。従って、長期間の開閉による振動によっても緩みが発生し難く、ドアの取付け姿勢が長期にわたって安定する。
(4)開口枠に高い強度が要求されないので、開口枠の低廉化を図ることができる。
ドアを、開口枠ではなく、実質的に躯体で支持するので、開口枠はドアを支える必要がない。従って、肉薄かつ簡易な中空構造のものを使用することができ、低廉なものを使用することができる。
(5)ドア開口部を広くすることができる。
開口枠を肉薄なものとすることができるので、その分、ドア開口部の幅や高さを広くすることができる。
【0018】
また、請求項2に記載の発明によれば、請求項1に記載の発明の作用効果に加えて、第二プレートとそれに結合された第一プレートそしてその第一プレートに結合された枠側ベース部材から構成される部品が、ドア側ベース部材に対して分離可能で、それらはドア側ベース部材に形成されたスリットに簡単に差し込むだけでワンタッチでドア表側にもドア裏側にも何度でも取付けることができる。よって、いわゆる左吊元用・右吊元用のいずれか現場の要求に簡単にかつ迅速に応じることができる。
【0019】
また、これにより、第一プレート,第二プレート及び枠側ベース部材からなる部品をドア側ベース部材から取外した状態で梱包することができる。しかも、ドア側ベース部材は、ドアから突出することなくドア端部に埋設されるので搬送時の安定性が良い。
【0020】
さらに、請求項3に記載の発明によれば、請求項2に記載の発明の作用効果に加えて、調整螺子又は調整カムによって、開口枠に対してドアを上下方向,ドア閉時のドア面に沿った左右方向,及びドア閉時のドア厚み方向にそれぞれ移動させることができるので、取付けの際あるいは取付け後に微調整する場合に有効である。
【0021】
また、請求項4に記載の発明によれば、請求項2または3に記載の発明の作用効果に加えて、ロック機構は、例えばスプリングバネ,係止片や板バネを利用した弾性突部からなるものであるので構造がシンプルである。また、解除も弾性突部を収縮させるだけでよいので簡単である。
【0022】
【発明の実施の形態】
本発明の実施形態について図面を参照して説明する。
図1に示すように、開口枠10は、上下に、本発明に係るドア取付け金具がH,Hが取付けられた蝶番側縦枠材11と,ハンドルLの回動によってドア20から進退するラッチR1を受け入れ可能なラッチ受け具R2が付けられた、蝶番側縦枠材11と同長のラッチ受け具側縦枠材12と,両者の上端部間に挿入、結合された上枠材13と,より構成される。
【0023】
ドア取付け金具Hは、図2乃至図6に示すように、後端部同士がヒンジ結合された第一プレート31と第二プレート32と、それら第一プレート31と第二プレート32の先端部にそれぞれ結合された枠側ベース部材41とドア側ベース部材42よりなり、それによって、開口枠10に対してドア20が回動自在に保持されるよう構成されている。図4に示すように枠側ベース部材41は開口枠10に取付けられ、ドア側ベース部材42はドア20の端部に取付けられる。
【0024】
また、枠側ベース部材41には、開口枠10を貫通し、内周面に雌ネジを有する短円筒状の雌ネジ部41bが設けられている。この雌ネジ部41bには、開口枠10側である一方端部に六角孔60bを有するとともに外周面に雄ネジを有する円筒状の雄ネジ部材60が螺合される。また、当該雄ネジ部材60の躯体70側には、躯体70に当接し、雄ネジ部材60の他方端部と回転自在かつ抜け出し不能に組付く略平板状の受け部材61が設けられている。さらに、雄ネジ部材60と受け部材61の中央部には、ネジ孔60a,61aが形成されている。
【0025】
このドア取付け金具Hの使用状態を、図1および図2に示す。開口枠10にはドア取付け金具Hの枠側ベース部材41がネジによって固定され、また、当該開口枠10は、枠側ベース部材41や固定ネジ62等によって躯体(柱)70に取付けられる。この状態で、ドア20の取付け位置を調整するには、雄ネジ部材60の六角孔60bに六角レンチを差し込んで当該雄ネジ部材60を回転させる。このとき、雄ネジ部材60の端部は受け部材61に回転自在かつ抜け出し不能に組付けられているので、その位置で円滑に回転する。
【0026】
雄ネジ部材60が回転することによって、それに螺合している雌ネジ部41b(枠側ベース部材41)が回転し、これに伴い、開口枠10が躯体70に対して左または右方向へ移動する。これによって、開口枠10を微動させ、その取付け位置を容易に調整することができる。
【0027】
このドア取付け金具Hについてさらに詳細に説明する。ドア側ベース部材42は、ドア20の厚み方向(表裏方向)に左右対称の形状であり、ドア20端部に埋設され、ドア20から突出することなく、複数のねじNによって固定される。すなわち、その幅(最大の幅)はドア20の端面の幅に等しく、ドア20端面から、開口枠10側に突出しないものである。
【0028】
また、ドア側ベース部材42の中央部には、ドア20の厚み方向に貫通し、第二プレート32の先端部をドア20の表側(図5及び図6において右側)からも裏側(図5及び図6において左側)からも差込み案内可能なスリット44が形成されている。また、そのスリット44に案内された第二プレート32を係止するロック機構が設けられている。なお、図示は省略したが第二プレート32の挿入方向とは逆側のスリット44に開口部を覆うキャップを装着してもよい。
【0029】
ロック機構は、スリット44に挿入された第二プレート32に当接する間は収縮するが、挿入にしたがって第二プレート32の先端部中央に設けられた孔34の位置に達すると伸長して孔34を係止する弾性突部からなる。弾性突部は、より具体的には、図7,図8に示すようなスプリングバネ51とそれを介してドア側ベース部材42の厚み方向に突出する係止片52から構成される。図7は、スプリングバネ51が収縮して係止片52が押し込められた状態を示し、図8は、スプリングバネ51が伸長して突出した係止片52で第二プレート32が係止された状態を示す。
【0030】
弾性突部は、第二プレート32のドア20表側からの挿入,ドア裏側からの挿入に関係なく機能するように、係止片52の先端外周にはテーパー面が形成されている。なお、弾性突部として、スプリングバネ51の機能と係止片52の機能とを一体化した板ばねを使用することもできる。
このように、先端部に枠側ベース部材41が結合された第二プレート32とドア側ベース部材42との結合は、ワンタッチで行うことができる。
【0031】
またスリット44を介して係止片52に相対向するドア側ベース部材42の位置には孔46が形成されていて、係止片52による係止を解除させるには、孔46にドライバー等の棒状先端部を差し込み係止片52に当接させ押し込むことにより行われる。すなわち、伸長したスプリングバネ51は収縮させられ、係止片52が押し込まれることにより係止が解除される。
【0032】
第二プレート32の後端部には、図9に示すように、筒状部36が設けられている。筒状部36には切欠き部が設けられたカラー38が嵌め込まれ、カラー38が一体化された筒状部36は、第一プレート31の後端部の上下に間をあけて設けられた筒状の軸受部33,33の間に、鉛直軸35を介して回動自在に取付けられる。軸受部33,33の内側に設けられたねじ部に、鉛直軸35の上下から高さ調整ねじ37,37が螺合されている。調整ねじ37,37の内側には鉛直軸35を受ける凹部37aが形成され、その逆の外側には六角ねじが嵌合される孔37bが形成されている。調整ねじ37は軸受部33よりも長く、調整ねじ37を上下方向に移動することにより調整ねじ37の端部を筒状部36に当接させ、これにより第二プレート32の後端部が、第一プレート31の後端部に対して上下方向に移動自在になるようにされている。その結果、開口枠10に対するドア20の上下方向の微調整が可能となる。調整ねじ37,37の上下には装飾用キャップ39,39が取付けられている。
【0033】
次に第一プレート31の先端部は、枠側ベース部材41に形成された縦長孔43に挿入されている。そして、図6に示すように、第一プレート31の先端部上部には枠側ベース部材41に設けられた調整カム45が嵌め込まれる間隙部31aが設けられ、調整カム45の回転により枠側ベース部材41に対する第一プレート31の位置関係が接近または離間自在にされている。その結果、開口枠10に対するドア20の前後方向(ドア20を閉じた場合のドア20の厚み方向)の微調整が可能となる。なお、調整カム45にかえて、例えば第一プレート31側壁にねじ溝を形成し、その溝に螺合する調整螺子を枠側ベース部材41に設けるようにしてもよい。
【0034】
また、第一プレート31の先端部が挿入される、枠側ベース部材41に形成された縦長孔43の幅は、図7,図8に示すように、第一プレート31の板厚よりも幅広(本実施形態例では第一プレート31の板厚のおよび2倍とした)に設定され、第一プレート31が縦長孔43内で第一プレート31の厚み方向に移動自在にされている。そして、第一プレート31の先端部前側は固定ねじ47により枠側ベース部材41に固定され、その先端部後側には調整用イモねじ49が取付けられている。調整用イモねじ49の調整により、第一プレート31は固定ねじ47で固定された部位を支点にして第一プレート31の厚み方向に移動自在にされている。その結果、開口枠10に対するドア20の左右方向(ドア20を閉じた場合のドア20の厚み方向及び上下方向にともに直角な方向)の微調整が可能となる。図7は、第一プレート31が枠側ベース部材41の内側(図7の上側)に移動してドア20閉時にはドア20の端部が枠側ベース部材41に接近する状態を示し、図8は、第一プレート31が枠側ベース部材41の外側(図7の下側)に移動してドア20閉時にはドア20の端部が枠側ベース部材41から離間する状態を示す。
【0035】
なお、固定ねじ47を緩めると第一プレート31の先端部は調整用イモねじ49が取付けられた状態で上述した調整カム45の作用により枠側ベース部材41に接離自在になるように固定ねじ47が貫通する第一プレート31の孔31b及び調整用イモねじ49が嵌め込まれる枠側ベース部材41の孔41aはともに横長孔にされている。
【0036】
以上のように構成されたドア取付け金具Hによれば、それのみによってドア20を開口枠10に取付けることができると共に、その開口枠10を躯体70に取付けることができるので、次のような作用効果を発揮する。
(1)ドア取付け金具Hのみでドアと開口枠の取付けができるので、取付け作業が容易であり、部品としての取り扱いも容易となる。
(2)構造が簡単で、調整が容易である。
従来のように、ドア20を開口枠10に取付けるための蝶番Cと、開口枠10を躯体に取付けるための固定金具Kをそれぞれ別々に取付け、かつそれぞれの調整機構を別々に調整する必要がないため、ドア20の建付け調整が容易である。
(3)ネジが緩み難く、ドア20の取付け姿勢が安定する。
調整部分が少なく、ネジの数も少ないので、その分、ネジの緩みが発生し難い。従って、長期間の開閉による振動によっても緩みが発生し難く、ドア20の取付け姿勢が長期にわたって安定する。
(4)開口枠10に高い強度が要求されないので、開口枠10の低廉化を図ることができる。
ドア20を、開口枠10ではなく、実質的に躯体70で支持するので、開口枠10はドア20の重量を支える必要がない。従って、肉薄かつ簡易な中空構造のものを使用することができ、低廉な開口枠10を使用することができる。例えば、通常の高級ドア20の場合、重量が25〜35kg程度であるので、開口枠10の肉厚は少なくとも30mm程度必要であるが、15mm程度で充分である。これにより、開口枠10を廉価なものとすることができる。
(5)ドア開口部を広くすることができる。
開口枠10を肉薄なものとすることができるので、その分、ドア開口部の幅や高さを広くすることができる。開口枠10の肉厚を30mmから15mmにすれば、開口枠10の幅を30mm広くすることができる。
【0037】
さらに、本発明の実施形態に係るドア取付け金具Hは、以下の作用効果を発揮する。すなわち、枠側ベース部材41が結合された第一プレート31とそれにヒンジ結合された第二プレート32からなるものは、ドア側ベース部材42に対して分離型であり、ドア20の表側からも裏側からも容易に取付けることができるので、現場の要求が左吊元用・右吊元用いずれであっても、その要求に迅速に対応可能である。この場合には所定位置で枠側ベース部材41を開口枠10にねじN止めすればよい。
【0038】
また、梱包時にドア20にはドア側ベース部材42だけが埋設されドア表側又は裏側に突出部はないので梱包は簡単であり、特に緩衝材等を必要としない。
【0039】
【発明の効果】
以上のとおり、請求項1に記載の発明に係るドア取付け金具は、それのみによってドアを開口枠に取付けることができると共に、その開口枠を躯体に取付けることができるので、次の作用効果を発揮する。(1)ドアと開口枠の取付けが容易であり、ドア取付け金具の取り扱いが容易である。(2)構造が簡単で、調整部分が少ないので、調整が容易である。(3)ネジが緩み難く、ドアの取付け姿勢が安定する。(4)開口枠に高い強度が要求されないので、開口枠の低廉化を図ることができる。(5)ドア開口部を広くすることができる。
【0040】
また、請求項2に記載の発明によれば、請求項1に記載の発明の作用効果に加えて、第一プレート,第二プレート及び枠側ベース部材からなる部品は、ドア側ベース部材に対して分離可能で、それらはドア側ベース部材に形成されたスリットに簡単に差し込むだけでワンタッチでドア表側にもドア裏側にも何度でも取付けることができるので、左吊元用・右吊元用のいずれか現場の要求に簡単にかつ迅速に応じることができる。また、ドア表側からドア裏側、あるいはその逆に移動させる場合に、従来のように木ネジ等を外したり取付けることは不要であるので、施工が簡単で、しかも木ネジ等の保持力の低下等のデメリットを考慮する必要はない。
【0041】
これにより、第一プレート,第二プレート及び枠側ベース部材からなる部品をドア側ベース部材から取外した状態で梱包することができるので、搬送時に外部からの衝撃で変形破損するおそれはなく、搬送時の安定性が良い。しかも余分な緩衝材を必要としないのでコストの低廉が図れる。しかも、ドア側ベース部材は、ドアから突出することなくドア端部に埋設されるので、搬送時の安定性はより良い。
【0042】

TECHNICAL FIELD OF THE INVENTION
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door mounting bracket capable of rotatably mounting a door to an opening frame and mounting the opening frame to a frame such as a pillar.
[0002]
[Prior art]
In a general building, as shown in FIGS. 1 and 10, the door 20 is rotatably attached to an opening frame 10 by a hinge C, and the opening frame 10 is attached to a frame 70 such as a pillar by another fixing bracket. Installed with K. Accordingly, the door 20 is substantially supported by the opening frame 10.
[0003]
Normally, the weight of the door 20 is about 15 kg even in a hollow so-called flush structure, and about 40 kg in a high-end product using solid wood. Therefore, the interval between the door 20 and the opening frame 10 or the distance between the opening frame 10 and the frame 70 changes due to daily opening and closing, distortion of the building, or loosening of the screws for attaching the door 20 and the opening frame 10, and the door mounting. In a few years later, problems such as the door 20 coming into contact with the opening frame 10 are likely to occur.
[0004]
If the cause is mere loosening of the screw, it can be dealt with by retightening the screw, but it is difficult to correct it with the other hinge C or the fixing bracket K itself. In the past, it relied on tedious adjustments such as scraping off the contacting part of the door 20 with a plane or the like, or slightly shifting the mounting position of the hinge C.
[0005]
In view of these points, in recent years, hinges C that incorporate an adjustment mechanism so that the mounting position of the door 20 can be modified have been developed and have been widely used.
For example, the hinge filed by the applicant of the present invention (Japanese Patent Application Laid-Open No. 2001-220938) can be finely adjusted by moving the door up and down, left and right, and front and rear.
[0006]
On the other hand, with respect to the position adjustment between the opening frame 10 and the frame 70, a fixing bracket capable of adjusting the distance between the two has been developed and used (for example, Japanese Patent No. 2929002 and Japanese Patent No. 2966792). Adjustment bracket).
[0007]
[Problems to be solved by the invention]
However, such a conventional door mounting structure has the following problems.
(1) Since two separate members such as hinges and fixing brackets are required, installation is troublesome, and handling (transportation and the like) is troublesome.
(2) Adjustment is troublesome because the structure is complicated and there are many adjustment parts.
Since it is necessary to separately install hinges for attaching the door to the opening frame and fixing brackets for attaching the opening frame to the frame, and adjust each adjustment mechanism separately, many adjustments are required for door installation adjustment. Takes time. That is, at the time of door installation, first, the frame is attached to the frame with the fixing bracket, the position is finely adjusted by the adjusting mechanism of the fixing bracket, then the door is attached to the frame with the hinge, and then the hinge adjusting mechanism is attached. It is necessary to fine-tune the position of the door. At this time, if the door cannot be mounted at an appropriate position by the hinge adjustment mechanism, it is necessary to temporarily remove the door from the opening frame, re-adjust the positional relationship of the opening frame to the frame, and mount the door again. Adjustment is cumbersome.
(3) The screws are easily loosened, and the mounting posture of the door tends to be unstable.
Since there are many adjustment portions and a large number of screws are used, the screws are likely to be loosened accordingly. In particular, the hinges used to attach the door to the opening frame are made using wood screws, so vibrations caused by long-term opening and closing tend to cause loosening, resulting in adverse effects such as the door tilting over time. easy.
(4) A high strength is required for the opening frame, which is expensive.
Since the opening frame is attached to the skeleton by a fixing bracket, and a door is attached to the opening frame by a hinge, a high strength is required for the opening frame in order to stably maintain these attaching postures. Therefore, a thick and heavy plywood or the like must be used for the opening frame, and the price becomes expensive.

As shown in FIGS. 2 to 6, the door mounting bracket H includes a first plate 31 and a second plate 32 having rear ends hinged to each other, and a front end of the first plate 31 and the second plate 32. It comprises a frame-side base member 41 and a door-side base member 42 which are respectively coupled to each other, whereby the door 20 is held rotatably with respect to the opening frame 10. As shown in FIG. 4, the frame-side base member 41 is attached to the opening frame 10, and the door-side base member 42 is attached to an end of the door 20.
[0024]
The frame-side base member 41 is provided with a short cylindrical female screw portion 41b penetrating the opening frame 10 and having a female screw on the inner peripheral surface. A cylindrical male screw member 60 having a hexagonal hole 60b at one end on the opening frame 10 side and having a male screw on the outer peripheral surface is screwed to the female screw portion 41b. A substantially flat receiving member 61 is provided on the side of the skeleton 70 of the male screw member 60 and is in contact with the skeleton 70 and is rotatably and irreversibly assembled with the other end of the male screw member 60. Further, screw holes 60a and 61a are formed in the central portions of the male screw member 60 and the receiving member 61.
[0025]
FIGS. 1 and 2 show the use state of the door mounting bracket H. FIG. The frame-side base member 41 of the door mounting bracket H is fixed to the opening frame 10 by screws, and the opening frame 10 is attached to the frame (column) 70 by the frame-side base member 41, fixing screws 62, and the like. To adjust the mounting position of the door 20 in this state, a hexagon wrench is inserted into the hexagonal hole 60b of the male screw member 60 and the male screw member 60 is rotated. At this time, since the end of the male screw member 60 is rotatably and non-extractably assembled to the receiving member 61, the male screw member 60 smoothly rotates at that position.
[0026]
When the male screw member 60 rotates, the female screw portion 41b (frame-side base member 41) screwed thereto rotates, and accordingly, the opening frame 10 moves leftward or rightward with respect to the frame 70. I do. Thereby, the opening frame 10 can be finely moved, and the mounting position thereof can be easily adjusted.
[0027]
The door fitting H will be described in more detail. The door-side base member 42 has a symmetrical shape in the thickness direction (front and back direction) of the door 20, is embedded at the end of the door 20, and is fixed by a plurality of screws N without protruding from the door 20. That is, the width (maximum width) is equal to the width of the end face of the door 20 and does not protrude from the end face of the door 20 toward the opening frame 10.
[0028]
In addition, the central portion of the door-side base member 42 penetrates in the thickness direction of the door 20, and the leading end of the second plate 32 extends from the front side of the door 20 (the right side in FIGS. A slit 44 that can be inserted and guided also from the left side in FIG. 6) is formed. Further, a lock mechanism for locking the second plate 32 guided by the slit 44 is provided. Although not shown, a cap that covers the opening may be attached to the slit 44 on the side opposite to the direction in which the second plate 32 is inserted.
[0029]
The lock mechanism contracts while abutting on the second plate 32 inserted into the slit 44, but expands when reaching the position of the hole 34 provided at the center of the distal end of the second plate 32 as it is inserted, and extends. And an elastic projection for locking. More specifically, the elastic projection is constituted by a spring spring 51 as shown in FIGS. 7 and 8 and a locking piece 52 projecting in the thickness direction of the door-side base member 42 via the spring. FIG. 7 shows a state in which the spring spring 51 is contracted and the locking piece 52 is pushed in, and FIG. 8 shows that the second plate 32 is locked by the locking piece 52 in which the spring spring 51 is extended and protruded. Indicates the status.
[0030]
The elastic projection has a tapered surface on the outer periphery of the distal end of the locking piece 52 so that the elastic projection functions regardless of whether the second plate 32 is inserted from the front side of the door 20 or the rear side of the door. In addition, a leaf spring in which the function of the spring spring 51 and the function of the locking piece 52 are integrated may be used as the elastic projection.
As described above, the connection between the second plate 32 having the frame-side base member 41 connected to the distal end portion and the door-side base member 42 can be performed with one touch.
[0031]
A hole 46 is formed at a position of the door-side base member 42 opposite to the locking piece 52 through the slit 44. To release the locking by the locking piece 52, a hole such as a screwdriver is inserted into the hole 46. This is performed by inserting the rod-shaped tip into the locking piece 52 and pushing it. That is, the extended spring spring 51 is contracted, and the engagement is released by pushing the engagement piece 52.
[0032]
At the rear end of the second plate 32, a tubular portion 36 is provided as shown in FIG. A collar 38 provided with a notch is fitted into the cylindrical portion 36, and the cylindrical portion 36 with the integrated collar 38 is provided with a space above and below the rear end of the first plate 31. It is rotatably mounted between the cylindrical bearing portions 33, 33 via a vertical shaft 35. Height adjusting screws 37, 37 are screwed from above and below the vertical shaft 35 into screw portions provided inside the bearing portions 33, 33. A concave portion 37a for receiving the vertical shaft 35 is formed inside the adjusting screws 37, 37, and a hole 37b into which a hexagonal screw is fitted is formed outside the adjusting screw 37. The adjusting screw 37 is longer than the bearing 33, and the end of the adjusting screw 37 is brought into contact with the cylindrical portion 36 by moving the adjusting screw 37 in the vertical direction, whereby the rear end of the second plate 32 is The first plate 31 is configured to be vertically movable with respect to the rear end. As a result, fine adjustment in the vertical direction of the door 20 with respect to the opening frame 10 can be performed. Decorative caps 39, 39 are mounted above and below the adjusting screws 37, 37, respectively.
[0033]
Next, the tip of the first plate 31 is inserted into a vertically long hole 43 formed in the frame-side base member 41. As shown in FIG. 6, a gap portion 31 a into which the adjustment cam 45 provided on the frame-side base member 41 is fitted is provided on the upper end portion of the first plate 31. The positional relationship of the first plate 31 with respect to the member 41 can be freely approached or separated. As a result, fine adjustment in the front-back direction of the door 20 with respect to the opening frame 10 (the thickness direction of the door 20 when the door 20 is closed) can be performed. Instead of the adjusting cam 45, for example, a thread groove may be formed on the side wall of the first plate 31, and an adjusting screw screwed into the groove may be provided on the frame-side base member 41.
[0034]
Further, the width of the vertically long hole 43 formed in the frame-side base member 41 into which the tip of the first plate 31 is inserted is wider than the thickness of the first plate 31 as shown in FIGS. (In this embodiment, the thickness is set to twice the thickness of the first plate 31), and the first plate 31 is movable in the thickness direction of the first plate 31 in the vertically long hole 43. The front end of the first plate 31 at the front end is fixed to the frame-side base member 41 by a fixing screw 47, and an adjustment pot screw 49 is attached to the rear end of the front end. By adjusting the adjusting screw 49, the first plate 31 is movable in the thickness direction of the first plate 31 with the portion fixed by the fixing screw 47 as a fulcrum. As a result, fine adjustment in the left-right direction of the door 20 with respect to the opening frame 10 (in the direction perpendicular to both the thickness direction and the vertical direction of the door 20 when the door 20 is closed) can be performed. FIG. 7 shows a state in which the first plate 31 moves inside the frame-side base member 41 (upper side in FIG. 7) and the end of the door 20 approaches the frame-side base member 41 when the door 20 is closed. 7 shows a state in which the first plate 31 moves to the outside of the frame-side base member 41 (the lower side in FIG. 7), and when the door 20 is closed, the end of the door 20 is separated from the frame-side base member 41.
[0035]
When the fixing screw 47 is loosened, the tip of the first plate 31 is fixed to the frame-side base member 41 by the action of the adjusting cam 45 with the adjusting cam screw 49 attached. Both the hole 31b of the first plate 31 through which the hole 47 penetrates and the hole 41a of the frame-side base member 41 into which the adjusting potion screw 49 is fitted are elongated holes.
[0036]
According to the door mounting bracket H configured as described above, the door 20 can be mounted on the opening frame 10 by itself, and the opening frame 10 can be mounted on the frame 70 by itself. It is effective.
(1) Since the door and the opening frame can be mounted only with the door mounting bracket H, the mounting operation is easy and the handling as a part is also easy.
(2) Simple structure and easy adjustment.
Unlike the related art, the hinge C for attaching the door 20 to the opening frame 10 and the fixing bracket K for attaching the opening frame 10 to the frame are separately attached, and there is no need to separately adjust the respective adjustment mechanisms. Therefore, the installation adjustment of the door 20 is easy.
(3) The screws are not easily loosened, and the mounting posture of the door 20 is stabilized.
Since the number of adjustment parts is small and the number of screws is small, loosening of screws is less likely to occur. Therefore, loosening is unlikely to occur even by vibration due to long-term opening and closing, and the mounting posture of the door 20 is stabilized for a long time.
(4) Since high strength is not required for the opening frame 10, the cost of the opening frame 10 can be reduced.
Since the door 20 is substantially supported by the frame 70 instead of the opening frame 10, the opening frame 10 does not need to support the weight of the door 20. Therefore, a thin and simple hollow structure can be used, and the inexpensive opening frame 10 can be used. For example, in the case of a normal high-end door 20, since the weight is about 25 to 35 kg, the thickness of the opening frame 10 needs to be at least about 30 mm, but about 15 mm is sufficient. Thereby, the opening frame 10 can be made inexpensive.
(5) The door opening can be widened.
Since the opening frame 10 can be made thinner, the width and height of the door opening can be increased accordingly. If the thickness of the opening frame 10 is changed from 30 mm to 15 mm, the width of the opening frame 10 can be increased by 30 mm.
[0037]
Further, the door fitting H according to the embodiment of the present invention exhibits the following operation and effects. That is, the first plate 31 to which the frame-side base member 41 is connected and the second plate 32 hinged to the first plate 31 are separate from the door-side base member 42, Since it can be easily installed from the factory, it is possible to quickly respond to the request of the site whether it is for the left suspension or the right suspension. In this case, the frame-side base member 41 may be screwed to the opening frame 10 at a predetermined position.
[0038]
Further, since only the door-side base member 42 is buried in the door 20 at the time of packing and there is no protrusion on the front side or the back side of the door, the packing is simple, and a cushioning material or the like is not particularly required.
[0039]
【The invention's effect】
As described above, the door mounting bracket according to the first aspect of the present invention enables the door to be mounted on the opening frame by itself, and also allows the opening frame to be mounted on the skeleton, thereby exhibiting the following operational effects. I do. (1) The door and the opening frame can be easily mounted, and the door mounting bracket can be easily handled. (2) The adjustment is easy because the structure is simple and there are few adjustment parts. (3) The screws are not easily loosened, and the mounting posture of the door is stabilized. (4) Since high strength is not required for the opening frame, the cost of the opening frame can be reduced. (5) The door opening can be widened.

According to the second aspect of the present invention, in addition to the functions and effects of the first aspect, the component including the first plate, the second plate, and the frame-side base member is disposed with respect to the door-side base member. It can be detached and easily inserted into the slit formed in the base member on the door side, and it can be mounted on the front side of the door or the back side of the door any number of times with one touch. Can easily and quickly respond to the requirements of the site. In addition, when moving from the front side of the door to the back side of the door or vice versa, it is not necessary to remove or attach a wood screw or the like as in the conventional case, so the construction is simple and the holding force of the wood screw etc. is reduced. There is no need to consider the disadvantages.
[0041]
This allows the components including the first plate, the second plate, and the frame-side base member to be packed in a state where the components are removed from the door-side base member. Good stability at time. In addition, since no extra cushioning material is required, the cost can be reduced. In addition, since the door-side base member is buried at the door end without protruding from the door, the stability at the time of transportation is better.
[0042]
Furthermore, in the case of a hinge that can be inserted and removed vertically, the door is temporarily lifted and the vertical shaft cylinder is dropped onto the vertical shaft on the opening frame side, so that the space above the vertical shaft is required at the top of the door. If there is no space of at least about 10 cm, the door cannot be mounted, and the mounting becomes difficult depending on the surrounding conditions. However, according to the present invention, the door is hinged to the first plate connected to the frame-side base member. Since only the second plate needs to be inserted horizontally into the door-side base member, it is possible to cope with an obstacle around the door or a case where there is almost no space above the door.
[0043]
According to the third aspect of the invention, in addition to the functions and effects of the second aspect of the invention, the door is vertically moved with respect to the opening frame by the adjusting screw or the adjusting cam, and the door surface when the door is closed. Can be moved in the left-right direction along the direction of the door and the thickness direction of the door when the door is closed, which is effective for fine adjustment at the time of installation or after installation.
[0044]
According to the fourth aspect of the present invention, in addition to the functions and effects of the second or third aspect of the present invention, the lock mechanism is formed by an elastic projection using, for example, a spring, a locking piece or a plate spring. Therefore, the structure is simple. In addition, the release is simple because only the elastic protrusions need to be contracted.
