Description

【０００１】
【発明の属する技術分野】
本発明は建具用開口枠固定金具に係り、たとえば、柱体等の建具取付部に扉体等を開閉自在に取り付ける開口枠体を固定するものに関する。
【０００２】
【従来の技術】
従来、この種の建具用開口枠固定金具としては、たとえば、特開平９−１１２１３５号公報に記載されているように、建具取付部に取り付ける開口枠体に埋込み固定する雄ねじ部を有する円筒状の調整固定具の外端部にこの調整固定具の径より大きい座金を回転自在にかつ軸方向に移動不能に取り付け、この調整固定具に前記開口枠体を前記建具取付部に固定する固定ねじを挿入する構成が知られている。
【０００３】
また、実用新案登録第３０２８８８９号公報に記載されているように、開口枠固定金具は建具取付部に取り付ける開口枠体にねじ込む第１のねじ軸部と、前記建具取付部にねじ込む第２のねじ軸部と、を有し、前記第１のねじ軸部と第２のねじ軸部とは互いに回転自在にかつ軸方向に移動不能に連結する構成が知られている。
【０００４】
【発明が解決しようとする課題】
前記特開平９−１１２１３５号公報に記載の構成では、開口枠体に調整固定具を取り付けるときは、調整固定具の外端部にこの調整固定具の径より大きい座金を有するので、この調整固定具の雄ねじ部の内端部を開口枠体の外側面から螺合し、この開口枠体の内側面から前記調整固定具を回転操作して調整固定具の雄ねじ部を開口枠体の内側に向かって引き込んで開口枠体に埋設し、この調整固定具の雄ねじ部の外端部と座金との間及び座金を開口枠体の外側面から外方に向かって突出させるため、開口枠体に対する調整固定具の取り付けに手数を要し、開口枠体の外側面から突出させる座金の突出量を建具取付部と開口枠体との間の間隔を調整して突出しなければならず、すなわち、建具取付部に開口枠体を取り付ける際には座金を建具取付部に当接した状態で調整固定具から座金を介して建具取付部に固定ねじを挿入するため、座金は建具取付部に当接する状態に突出しなければならず、さらに、建具取付部と開口枠体との間の間隔を調整する際には開口枠体に埋設した調整固定具を回動操作する手数を要し、したがって、現場作業が簡単ではなく、作業能率を向上する上で好ましくない、という問題がある。また、現場とは別に工場等で開口枠体に調整固定具をあらかじめ取り付けて現場に運搬するようにすると、開口枠体の外側面から調整固定具の雄ねじ部の外端部と座金との間及び座金が突出するため、梱包が容易でなく、整然と積み込み難く運搬上に不都合がある、という問題もある。
【０００５】
また、実用新案登録第３０２８８８９号公報に記載の構成では、第１のねじ軸部と第２のねじ軸部とは互いに回転自在にかつ軸方向に移動不能に連結され、全体として長さを有するため、この第１のねじ軸部と第２のねじ軸部とを開口枠体から建具取付部に真っ直ぐにねじ込むことが簡単ではなく、開口枠体に対する第１のねじ軸部と建具取付部に対する第２のねじ軸部とは同時にねじ込む必要があるため、特殊のねじ込み治具を必要とし、強いねじ込み力を必要とする、という問題がある。また、現場とは別に工場等で開口枠体に第１のねじ軸部をあらかじめ取り付けて現場に運搬するようにすると、開口枠体の外側面から第２のねじ軸部が突出するため、梱包が容易でなく、整然と積み込み難く運搬上に不都合がある、という問題もある。
【０００６】
本発明は、このような点に鑑みてなされたもので、現場作業が容易で、建具取付部に対する開口枠体の調整操作が容易で、工場等で開口枠体に固定具及びこの固定具に調整板を介して支持具を取り付けても開口枠体から調整ねじが突出することもなく、運搬する際も開口枠体を整然と積み込むことができる建具用開口枠固定金具を提供することを目的とするものである。
【０００７】
【課題を解決するための手段】
請求項１記載の発明は、建具取付部に取り付ける開口枠体に埋込み固定される円筒状の固定具と、この固定具内に嵌合され中心部にねじ軸挿通孔を有する調整板と、前記固定具に着脱可能に螺合されこの固定具内の前記調整板を軸方向に移動不能に支持する円筒状の支持具と、この支持具から前記調整板のねじ軸挿通孔に挿通され前記建具取付部に前記開口枠体を取り付ける調整ねじと、を具備し、前記固定具は、一端面に前記支持具を挿入する挿入口を開口するとともにこの挿入口に連通して前記支持具を螺合するねじ孔と、他端面に前記ねじ孔に連通して形成され前記調整ねじを挿通する挿通孔と、外周面に突設され前記開口枠体に圧入する圧入係止部と、を有し、前記調整板は、前記固定具のねじ孔の内端側に当接する当接部と、この当接部から中心部に向かってそれぞれ突出され先端部にて前記固定具の挿通孔に連通する前記ねじ軸挿通孔を形成した複数の弾性突片と、を有し、前記支持具は、外周面に形成され前記固定具のねじ孔に螺合するねじ部と、両端面に開口して形成され前記調整ねじを回動操作する治具挿入用の治具挿入孔と、この治具挿入孔の他端開口縁部に形成され前記固定具のねじ孔の内端側との間で前記調整板を挟持してこの調整板を軸方向に移動不能に支持する支持部と、を有し、前記調整ねじは、前記支持具の治具挿入孔内に位置してこの調整ねじをねじ込み操作する操作部と、この操作部に一体に形成され前記調整板のねじ軸挿通孔に前記複数の弾性突片に抗して挿通しこの複数の弾性突片の先端部にて軸方向に移動不能に係止される係止軸部及び前記建具取付部にねじ込む軸方向のねじ軸部と、を有する、ものである。
【０００８】
そして、固定具内に調整板及び支持具を組み込むときは、固定具のねじ孔内に調整板を嵌合し、このねじ孔の内端側に調整板の当接部を当接し、この固定具のねじ孔に支持具の外周部のねじ部を螺合して支持具を回動操作することにより、この支持具が固定具のねじ孔に深くねじ込まれ、この支持具の治具挿入孔の他端開口縁部の支持部が調整板の当接部に当接され、この支持具の支持部と固定具のねじ孔の内端側との間に調整板の当接部が挟持され、この調整板が固定される。したがって、固定具内に調整板及び支持具が簡単に組み込まれる。
【０００９】
また、開口枠体に調整板及び支持具を組み込んだ固定具を埋設するときは、開口枠体の埋設位置に固定具を挿入するとともに、この固定具内の支持具を回動操作することにより、この支持具にて固定具が回動され、この固定具の外周面の圧入係止部が埋設位置の内壁部に圧入される。そして、調整板及び支持具を組み込んだ固定具が開口枠体の埋設位置に埋設固定され、この固定具のねじ孔の一端面の挿入口が開口枠体の内側面に開口され、この固定具の他端面の挿通孔が開口枠体の外側面に開口される。したがって、調整板及び支持具を組み込んだ固定具が開口枠体の埋設位置に簡単に埋設固定される。
【００１０】
また、建具取付部に開口枠体を取付けるときは、建具取付部に開口枠体の外側面を対向して開口枠体を配置し、この開口枠体に固定された固定具のねじ孔に螺着された支持具の治具挿入孔から調整板のねじ軸挿通孔に調整ねじのねじ軸部を挿通し、この治具挿入孔内に位置した調整ねじの操作部を回動操作することにより、この調整ねじのねじ軸部が建具取付部に深くねじ込まれるとともに、この調整ねじの操作部側の係止軸部が調整板のねじ軸挿通孔を形成した複数の弾性突片に抗して挿通される。
【００１１】
そして、調整板のねじ軸挿通孔より大径の調整ねじの操作部が調整板のねじ軸挿通孔の開口縁部に当接されるとともに、この調整板のねじ軸挿通孔を形成した複数の弾性突片が弾性復帰してこの複数の弾性突片の先端部が調整ねじの係止軸部に圧着係止し、この複数の弾性突片の先端部にて調整ねじがこの調整ねじのねじ込み方向と反対方向に向かって抜け出すことを阻止される。すなわち、調整ねじは、固定具と支持具とにより挟持された複数の弾性突片を有する調整板にて軸方向に移動不能に確実に支持される。
【００１２】
したがって、開口枠体から建具取付部に調整ねじをねじ込み操作することにより、この調整ねじにて建具取付部に開口枠体が簡単に取り付けられる。
【００１３】
つぎに、建具取付部に取り付けた開口枠体を建具取付部に対して垂直状に調整して矯正する必要がある場合は、支持部の治具挿入孔から調整ねじの操作部にこの操作部を回動操作する操作治具を嵌合し、この操作治具にて操作部を回動操作することにより、この調整ねじの係止軸部が調整板の複数の弾性突片の先端部に対して回動されるとともに、この調整ねじのねじ軸部が建具取付部に対して調整回動されて進退回動される。
【００１４】
このとき、調整ねじは、固定具と支持具とにより挟持された複数の弾性突片を有する調整板にて軸方向に移動不能に支持されていることにより、この調整ねじが調整回動されて進退動されると、この調整ねじにて開口枠体が建具取付部に対して進退動されて間隔が調整され、この開口枠体が建具取付部に対して簡単に垂直状に矯正される。
【００１５】
したがって、調整板及び支持具を組み込んだ固定具を開口枠体の埋設位置に埋設固定し、この固定具内の支持具内から建具取付部に調整ねじを組付けることにより、建具取付部に対して開口枠体が簡単に取り付けられるため、現場作業が容易であり、また、調整ねじを調整操作することにより、建具取付部に対して開口枠体が簡単に垂直状に矯正される。
【００１６】
また、開口枠体に調整板及び支持具を組み込んだ固定具を埋設固定しても、この固定具等とは別体の調整ねじが開口枠体の外面に突出することがなく、工場で開口枠体に、調整板及び支持具を組み込んだ固定具をあらかじめ埋設固定しても、この開口枠体の梱包及び運搬が容易に行われる。
【００１７】
請求項２記載の発明は、請求項１記載の発明において、固定具は、一端面の挿入口の開口縁部にこの固定具を回動操作する複数の治具係合溝を有するとともに、ねじ孔の内端側に形成され調整板の当接部を当接する当接段部を有する、ものである。
【００１８】
そして、複数の治具係合溝に固定具を回動操作する操作治具を係合して操作治具を回動操作することにより、この操作治具にて固定具が確実に回動され、特に固定具を開口枠体から取外す際に有利である。また、固定具のねじ孔に調整板を嵌合することにより、この調整板の当接部が固定具の当接段部に当接され、この当接段部と支持具の支持部とにより調整板の当接部が確実に挟持され、この調整板にて調整ねじが軸方向に移動不能に確実に支持される。
【００１９】
請求項３記載の発明は、請求項１記載の発明において、支持具は、治具挿入孔の一端開口部にこの支持具を回動操作する多角形状の治具係合部を有するとともに、前記治具挿入孔の他端開口部内に調整ねじの操作部を回転自在に嵌合する、ものである。
【００２０】
そして、多角形状の治具係合部に支持具を回動操作する操作治具を係合して操作治具を回動操作することにより、この操作治具にて支持具が固定具のねじ孔に簡単にかつ確実に深くねじ込まれる。また、開口枠体に調整板及び支持具を組み込んだ固定具を埋設するときは、この支持具の治具係合部に操作治具を係合して操作治具を回動操作することにより、この操作治具にて支持具を介して固定具が回動され、この固定具の外周面の圧入係止部が埋設位置の内壁部に圧入される。そして、調整板及び支持具を組み込んだ固定具が開口枠体の埋設位置に確実に埋設固定される。また、治具挿入孔の他端開口部内に調整ねじの操作部を回転自在に嵌合することにより、治具挿入孔内において調整板に対して調整ねじの操作部が容易に調整回動される。
【００２１】

【００２６】
15は前記左右の柱体２に前記左右の側枠６を取り付ける建具用開口枠固定金具で、この開口枠固定金具15は、前記左右の側枠６に埋込み固定される円筒状の固定具16と、この固定具16内に嵌合される調整板31と、前記固定具16に着脱可能に螺合されこの固定具16内の前記調整板31を軸方向に移動不能に支持する円筒状の支持具18と、この支持具18から前記調整板31に挿通され前記左右の柱体２に前記左右の側枠６を取り付ける調整ねじ17と、を有して構成されている。
【００２７】
前記固定具16は、一端面に前記支持具18を挿入する挿入口19を開口するとともに、この挿入口19に連通して前記支持具18を他端面に向かって螺合する雌ねじ20を形成した軸方向のねじ孔21と、他端面に一体の閉塞板22の中心部に形成され前記ねじ孔21に連通して前記調整ねじ17を挿通する挿通孔23と、外周面に突設され前記左右の側枠６の小径孔部11に圧入する圧入係止部としての軸方向の螺旋状突条24と、前記一端面のねじ孔21の挿入口19の開口縁部に相対して形成されこの固定具16を回動操作する複数の治具係合溝25と、前記他端面の挿通孔23の開口縁部の近傍で前記ねじ孔21の内端側に形成された当接段部26と、を有して形成されている。
【００２８】
また、前記固定具16は全体として一端部から他端部に向かって順次縮径した形状に形成され、その外周面に突設された前記螺旋状突条24は一端部から他端部に向かって順次高さを低くして外周面に突設され、この螺旋状突条24に複数個の略三角形状の切欠部27が軸方向に沿って間隔をおいて形成され、この各切欠部27間の螺旋状突条24がそれぞれ独立して前記左右の側枠６の小径孔部11に食い込んで圧入されるようになっている。
【００２９】
前記調整ねじ17は、前記支持具18内に位置してこの調整ねじ17をねじ込み操作するプラス溝を有する大径頭部状の操作部28と、この操作部28に一体に形成され前記左右の柱体２にねじ込む軸方向のねじ軸部29a 及び前記調整板31に係止される係止軸部29b と、を有し、この係止軸部29b は前記操作部28側に位置して形成され、この係止軸部29b に連続して前記ねじ軸部29a が軸方向に一体に形成されている。
【００３０】
また、前記係止軸部29b は前記操作部28の近傍に位置して前記調整板31により係止される環状溝30を有している。また、前記ねじ軸部29a は軸方向に螺旋状の雄ねじ32を有している。
【００３１】
前記調整板31は、前記調整ねじ17のねじ軸部29a 及び係止軸部29b を回動自在に挿通するねじ軸挿通孔33a を有する前記調整ねじ17の操作部28より大径の円板状の座金33と、前記調整ねじ17のねじ軸部29a 及び係止軸部29b を挿通するねじ軸挿通孔34a を有する前記調整ねじ17の操作部28より大径のスプリングワッシャ35と、を有して構成されている。
【００３２】
また、前記スプリングワッシャ35は、前記固定具16のねじ孔21の内端側に形成された前記当接段部26に当接する環状の当接部35a と、この当接部35a から前記調整ねじ17のねじ込み方向に僅かに傾斜してこの当接部35a の中心部に向かってそれぞれ突出され先端部34b にて前記ねじ軸挿通孔34a を形成した複数の弾性突片34と、を有して形成されている。
【００３３】
前記ねじ軸挿通孔34a は、前記調整ねじ17のねじ軸部29a 及び係止軸部29b より僅かに小径に形成され、このねじ軸挿通孔34a に調整ねじ17のねじ軸部29a 及び係止軸部29b を挿通する際にはこのねじ軸挿通孔34a に前記複数の弾性突片34に抗して、すなわち、ねじ軸部29a 及び係止軸部29b の外周部にて前記複数の弾性突片34を弾性変形させて、このねじ軸挿通孔34a に調整ねじ17のねじ軸部29a 及び係止軸部29b が挿通されるようになっている。
【００３４】
また、この調整ねじ17の操作部28が前記座金33に当接するとともに、この調整ねじ17の係止軸部29b の環状溝30に前記複数の弾性突片34の先端部34b がそれぞれ嵌合し、この複数の弾性突片34の先端部34b にて調整ねじ17が軸方向に移動不能に係止されるようになっている。
【００３５】
前記支持具18は、外周面に形成され前記固定具16のねじ孔21の雌ねじ20に螺合する軸方向の雄ねじ36を有するねじ部37と、両端面に開口して形成され前記調整ねじ17の操作部28を回動操作する治具挿入孔38と、この治具挿入孔38の一端開口部に形成されこの支持具18を回動操作する多角形状の治具係合部39と、前記治具挿入孔38の他端開口部に形成され前記調整ねじ17の操作部28を回転自在に嵌合する嵌合部40と、前記治具挿入孔38の他端開口縁部に形成され前記固定具16の当接段部26との間で前記調整板31、すなわち座金33の周縁部及び前記スプリングワッシャ35の当接部35a を挟持してこの座金33及びスプリングワッシャ35を軸方向に移動不能に支持する支持部41と、を有して形成されている。
【００３６】
しかして、前記固定具16、前記調整ねじ17、前記支持具18及び前記調整板31は金属にてそれぞれ別体に形成されている。
【００３７】
つぎに、前記実施の形態の作用を説明する。
【００３８】
まず、各固定具16内に調整板31及び支持具18を組み込むときは、各固定具16のねじ孔21内に調整板31をそれぞれ嵌合し、この各ねじ孔21の内端側の当接段部26に調整板31、すなわちスプリングワッシャ35の当接部35a を当接するとともに、このスプリングワッシャ35の当接部35a に座金33の周縁部をそれぞれ当接することにより、このスプリングワッシャ35のねじ軸挿通孔34a に座金33のねじ軸挿通孔33a が連通される。
【００３９】
また、各固定具16のねじ孔21に支持具18の外周部のねじ部37を螺合して各支持具18を、この各支持具18の治具係合部39に係合した操作治具によりそれぞれ回動操作すると、この各支持具18がそれぞれの固定具16のねじ孔21にそれぞれ深くねじ込まれ、この各支持具18の治具挿入孔38の他端開口縁部の支持部41が調整板31の当接部、すなわち座金33の周縁部にそれぞれ当接され、この各支持具18の支持部41と各固定具16のねじ孔21の内端側の当接段部26との間に調整板31の当接部、すなわちスプリングワッシャ35の当接部35a 及び座金33の周縁部が挟持され、このスプリングワッシャ35及び座金33が各固定具16内に確実に固定される。したがって、各固定具16内に調整板31及び支持具18が簡単に組み込まれる。
【００４０】
また、開口枠体４の左右の側枠６に調整板31及び支持具18を組み込んだ固定具16を埋設するときは、開口枠体４の左右の側枠６の各固定具埋設孔９に固定具16をそれぞれ挿入するとともに、この各固定具16内の支持具18を、この各支持具18の治具係合部39に係合した操作治具によりそれぞれ回動操作すると、この各支持具18にて固定具16がそれぞれ回動され、この各固定具16の外周面の螺旋状突条24が固定具埋設孔９の小径孔部11の内壁部にねじ込まれて圧入される。そして、調整板31及び支持具18を組み込んだ各固定具16が小径孔部11にそれぞれ埋設固定されるとともに、この各固定具16の一端部が固定具埋設孔９の大径孔部11内にそれぞれ深く埋設される。
【００４１】
この際、各固定具16の外周面の螺旋状突条24は所定の間隔をおいて切欠部27を有するので、この各切欠部27間の螺旋状突条24がそれぞれ独立して小径孔部11の内壁部に喰い込み、その喰い込みが次第に深くなり、そして一旦喰い込んだ螺旋状突条24はそれぞれ独立して固定具16の回動を阻止し、したがって、各固定具16が小径孔部11に確実に埋設固定される。
【００４２】
そして、この各固定具16のねじ孔21の一端面の挿入口19が左右の側枠６の内側面にそれぞれ開口され、この各固定具16の他端面の挿通孔23が左右の側枠６の外側面にそれぞれ開口される。
【００４３】
したがって、左右の側枠６の各固定具埋設孔９内に調整板31及び支持具18を組み込んだ各固定具16がそれぞれ簡単に埋設固定され、かつ、この各固定具16は両側端が左右の側枠６の両面に突出することのない状態に埋設固定される。
【００４４】
つぎに、左右の枠体２に開口枠体４を取り付けるときは、左右の柱体２に左右の側枠６の外側面を対向して開口枠体４を配置し、この開口枠体４の左右の側枠６に固定された各固定具16のねじ孔21に螺着された各支持具18の治具挿入孔38から座金33のねじ軸挿通孔33a 及びスプリングワッシャ35のねじ軸挿通孔34a に調整ねじ17のねじ軸部29a をそれぞれ挿通し、この各治具挿入孔38内に位置した各調整ねじ17の操作部28をそれぞれ回動操作することにより、この各調整ねじ17のねじ軸部29a が左右の柱体２にそれぞれ深くねじ込まれるとともに、この各調整ねじ17の操作部28側の係止軸部29b が各調整板31のスプリングワッシャ35にねじ軸挿通孔34a を形成した複数の弾性突片34に抗してそれぞれ挿通される。
【００４５】
そして、各調整板31のスプリングワッシャ35のねじ軸挿通孔34a 及び座金33のねじ軸挿通孔33a より大径の各調整ねじ17の操作部28が座金33のねじ軸挿通孔33a の開口縁部に当接されるとともに、この各スプリングワッシャ35にねじ軸挿通孔34a を形成した複数の弾性突片34が弾性復帰してこの複数の弾性突片34の先端部34b が各調整ねじ17の係止軸部29b に形成された環状溝30にそれぞれ圧着係止し、この複数の弾性突片34の先端部34b にて各調整ねじ17がこの調整ねじ17のねじ込み方向と反対方向に向かって抜け出すことを阻止される。すなわち、各調整ねじ17は、各固定具16と各支持具18とにより挟持された複数の弾性突片34を有する調整板31にて軸方向に移動不能に確実に支持される。
【００４６】
したがって、左右の側枠６から左右の柱体２に各調整ねじ17をそれぞれねじ込み操作することにより、この各調整ねじ17にて左右の柱体２に左右の側枠６が簡単に取り付けられる。
【００４７】
つぎに、左右の柱体２に取り付けた開口枠体４の左右の側枠６を、左右の柱体２に対して垂直状に調整して矯正する必要がある場合は、その左右の側枠６を調整する位置の開口枠固定金具15の支持具18の治具挿入孔38から調整ねじ17の操作部28にこの操作部28を回動操作する操作治具（図示せず）を嵌合し、この操作治具にて操作部28を回動操作することにより、この調整ねじ17の係止軸部29b が環状溝30で調整板31の複数の弾性突片34の先端部34b に対して回動されるとともに、この調整ねじ17のねじ軸部29a が左右の柱体２に対して進退回動される。
【００４８】
このとき、調整ねじ17は、固定具16と支持具18とにより挟持された複数の弾性突片34を有する調整板31にて軸方向に移動不能に支持されていることにより、この調整ねじ17が調整回動されて進退動されると、この調整ねじ17にて左右の側枠６が左右の柱体２に対して進退動されて間隔５が調整され、この左右の側枠６が左右の柱体２に対して簡単に垂直状に矯正される。
【００４９】
そして、左右の側枠６の一部が左右の柱体２に近付き過ぎたり、離間し過ぎることを確実に防止され、この開口枠体４内に扉体等の開閉体をスムーズに開閉自在にかつ精度よく取り付けることができる。
【００５０】
したがって、調整板31及び支持具18を組み込んだ固定具16を開口枠体４の埋設位置に埋設固定し、この固定具16内の支持具18内から左右の柱体２に調整ねじ17を組付けることにより、左右の柱体２に対して開口枠体４の左右の側枠６が簡単に取り付けられるため、現場作業が容易であり、また、調整ねじ17を調整操作することにより、左右の柱体２に対して開口枠体４の左右の側枠６が簡単に垂直状に矯正される。
【００５１】
