Description

【０００１】
【発明の属する技術分野】
本発明は、扉を枠体に回転可能に取り付けるための蝶番に関するものである。
【０００２】
【従来の技術】
扉を枠体に取り付ける場合、軸心に回動可能に取り付けられた２枚の羽根板からなる蝶番を用い、一方の羽根板を枠体側に、他方の羽根板を扉側にビスなどで固定して、扉を枠体に回転可能に取り付けている。
また、枠体と扉とは、良好な状態で装着されるように設計されているが、通常、蝶番を介して枠体に扉を取り付けた後に、微調整が要求される。
【０００３】
そこで、蝶番を用いて扉を枠体に取り付けた後に、扉の高さ方向（以下、上下方向という場合もある）と扉の横幅方向（以下、左右方向という場合もある）の装着位置を微調整可能な蝶番が種々提案されている（たとえば特許文献１、特許文献２参照）。
【０００４】
特許文献１に記載の蝶番は、立て枠に、円周カムが形成された箱状の固定部材を固定し、この固定部材内に上下方向に摺動可能で、蝶番の一方の羽根板が固定された移動部材を設け、移動部材には固定部材の円周カムと当接する当接子が形成され、また、移動部材には、一方の羽根板の内面と当接する角度調整ネジが設けられている。
そして、円周カムの回動操作によって扉の上下方向の微調整が行われ、角度調整ネジの回動操作によって扉の左右方向の微調整が行われる。
【０００５】
特許文献２に記載の蝶番は、２枚の羽根板の軸心に小突起と雄ねじ部を設け、一方の羽根板の管部に円柱状の切り欠き部を設け、この切り欠き部に、内部に雌ねじ部を有する上下調整用ワッシャをはめ込み、雄ねじ部と雌ねじ部を係合させる。
また、一方の羽根板は、本体羽根板と、調整板と、調整板の回動を阻止し、上下移動を案内する調整板支持台を有し、この調整板支持台に左右調整用ネジを回動可能に設けている。

【発明が解決しようとする課題】
上述した特許文献１および２に記載の蝶番は、蝶番を用いて扉を枠体に取り付けた後に、扉の上下、左右方向の微調整を行うことが可能であるが、以下に示すような不利益がある。
【０００８】
特許文献１および２に記載の蝶番は、基本的に２つの羽根板を枠体と、この枠体に近接する扉の側部に取り付けるものであることから、一般的な住宅等に適用される扉等には適している。
しかしながら、特許文献１および２に記載の蝶番は、取り付けを近接した領域で行わなければならないことから、たとえば、いわゆるスィング仕様の比較的大型で重量のある扉の場合には、取り付け作業を細心の注意を払いながら行う必要があり、容易に取り付けることが困難である。
【０００９】
また、特許文献１および２に記載の蝶番は、２枚の羽根板を枠体と、この枠体に近接する扉の側部に取り付けることから、扉の上下、左右方向の微調整を行う場合にも、無理な姿勢で細心の注意を払いながら行う必要があり、調整自体が煩雑で手間がかかり、また、熟練を要する。
【００１０】
本発明は、かかる事情に鑑みてなされたものであり、その目的は、扉の大きさにかかわらず、細心の注意を払うことなく容易に取り付けることが可能で、また、無理な姿勢をしいることなく、また熟練を要することなく、扉の上下、左右方向の微調整を容易に行うことが可能な蝶番を提供することにある。
【００１１】

【００１８】
【発明の実施の形態】
以下、本発明の実施の形態を添付図面に関連付けて説明する。なお、説明の便宜上、一部の図面においては、透視図法を用いて示している。
【００１９】
図１（Ａ），（Ｂ）は、本発明に係る蝶番を採用した扉装置の一実施形態を示す外観図であって、図１（Ａ）は正面図、図１（Ｂ）は側面図である。なお、図１（Ａ）において、ハンドルを除く、蝶番は図中では実線で示してあるが、本実施形態では蝶番およびそれに付随するサブアーム等は扉本体の裏面側が配置され、装着される。
また、図２（Ａ）は図１（Ａ）のＡ−Ａ線矢視方向における断面図であって扉が開いた状態を示す図であり、２（Ｂ）は図１（Ａ）のＡ−Ａ線矢視方向における断面図であって扉が閉じた状態を示す図であり、２（Ｃ）は図１（Ａ）のＢ−Ｂ線矢視方向における断面図である。
【００２０】
本実施形態に係る扉装置１は、図１および図２の（Ａ），（Ｂ）に示すように、扉本体２、枠体としての支柱３ａ，３ｂ、蝶番部４、第１のサブアーム体５、第２のサブアーム体６、およびサブアーム取付部７を、主構成要素として有している。
また、図中、Ｃは天井を、Ｆは床面を、Ｗ１，Ｗ２は壁をそれぞれ示しており、本実施形態に係る扉装置１は、壁Ｗ１，Ｗ２間に形成された天井Ｃから床面Ｆに至る開放部（空間部）ＯＰに配置されて、所定のスィング動作によりこの開放部ＯＰを開閉するように装着される。
【００２１】
扉本体２は、たとえば、高さが２３００ｍｍ、横幅が３００ｍｍ、厚さが３０ｍｍに設定された板状をなし、前面側の左中央部に略コ字形状をなすハンドル２１が取り付けられている。
この場合、天井Ｃの高さは、床面Ｆから２３００ｍｍに設定される。
【００２２】
支柱３ａは、その第１側部３１ａが壁Ｗ１の開放部ＯＰに臨む端部の裏面側にネジ等により固定され、第２側部３２ａに蝶番部４、およびサブアーム取付部７の一端が取り付けられる。
支柱３ａの上端部３３ａは高さ調整ネジ部を含む固定具３４ａで天井Ｃに対して固定され、下端部３５ａは高さ調整ネジ部を含む固定具３６ａで床面Ｆに対して固定されている。
また、図１（Ｂ）に示すように、支柱３ａの上端側裏面がブラケット３７ａにより天井Ｃに対して固定され、下端側裏面がブラケット３８ｂにより床面Ｆに対して固定されている。
【００２３】
支柱３ｂは、その第１側部３１ｂが壁Ｗ２の開放部ＯＰに臨む端部の裏面側にネジ等により固定され、第２側部３２ｂにサブアーム取付部７の他端部が取り付けられる。
支柱３ｂの上端部３３ｂは高さ調整ネジ部を含む固定具３４ｂで天井Ｃに対して固定され、下端部３５ｂは高さ調整ネジ部を含む固定具３６ｂで床面Ｆに対して固定されている。
また、支柱３ｂの上端側裏面がブラケット（３７ｂ：図示せず）により天井Ｃに対して固定され、下端側裏面がブラケット（３８ｂ：図示せず）により床面Ｆに対して固定されている。
【００２４】
蝶番部４は、所定長さ（たとえば４００ｍｍ）を有し、一端側が支柱３ａの第２側部３２ａの第１の位置、たとえば天井Ｃから３５０ｍｍの位置に形成された取付ブラケット３９−１に回転可能に取り付けられ、他端側に長手方向に対して略直交する方向に第１の挿通孔が形成された第１のアーム体４１と、第１のアーム体４１の他端側の下方近傍の扉本体２に固定された第１の取付部４２と、第１のアーム体の第１の挿通孔を一端側から挿通された状態で当該一端側が第１の取付部４２の所定の位置に螺合され、他端側が第１のアーム体４１に対して第１の挿通孔を中心に回転可能に係合されている第１の取付軸４３と、所定長さ（たとえば４００ｍｍ）を有し、一端側が支柱３ａの第２側部３２ａの第２の位置、たとえば床面Ｆから３５０ｍｍの位置に形成された取付ブラケット３９−２に回転可能に取り付けられ、他端側に長手方向に対して略直交する方向に第２の挿通孔が形成された第２のアーム体４４と、第２のアーム体４４の他端側の下方近傍の扉本体２に固定された第２の取付部４５と、第２のアーム体４４の第２の挿通孔を一端側から挿通された状態で当該一端側が第２の取付部の所定の位置に螺合され、他端側が第２のアーム体４４に対して第２の挿通孔を中心に回転可能に係合されている第２の取付軸４６と、第１のアーム体４１の長手方向中央部と第２のアーム体４４の長手方向中央部とを連結する連結竿４７と、を有している。
【００２５】
以下、蝶番部４の第１および第２のアーム体４１，４４、並びに、第１および第２の取付部４２，４５の具体的な構成、取り付け構造、および機能について、図面に関連付けて説明する。なお、第１および第２のアーム体４１，４４は同様の構成を有することから、第１のアーム体４１を例として説明する。同様に、第１および第２の取付部４２，４５は同等の構成を有することから、第１の取付部４２を例として説明する。
【００２６】
図３（Ａ），（Ｂ）はアーム体４１の具体的な構成および取り付け構造を示す図であって、図３（Ａ）は上面図、図３（Ｂ）は裏面側から見た一部切欠裏面図である。
【００２７】
第１のアーム体４１は、図３（Ａ）に示すように、支柱３ａに取り付けられた一端側から一旦、扉本体２の裏面から離れるように斜めに延びるように形成された第１アーム部４１１ａと、第１アーム部４１１ａの先端部から扉本体２の裏面側の第１の取付部４２の固定位置の上方近傍に向かって延びるように形成された第２アーム部４１１ｂとを有する。
このように第１のアーム体４１は略Ｌ字状をなすように構成されており、第１アーム部４１１ａと第２アーム部４１１ｂとの連結部で空間部４１１ｃが形成される。この空間部４１１ｃにより、図２（Ａ）に示すように、扉装置１を開放状とするために扉本体２をスィングさせた際に、支柱３ａ，壁Ｗ１を避けて第１のアーム体４１１を回転させることができる。
好適には、空間部４１１ｃに臨む第１アーム部４１１ａの内壁側は、図２および図３の（Ａ）に示すように、支柱３ａ，壁Ｗ１とにそれぞれ対応したステップ形状をとることが望ましい。
【００２８】
第１アーム部４１１ａの後端側に、支柱３ａに取り付けられた取付ブラケット３９−１に対して回転可能に軸支するための回転孔４１２が形成されている。そして、この回転孔４１２に対して両端が取付ブラケット３９−１内でナット等により固定された回転軸３９ａが挿通されている。そして、取付ブラケット３９−１と第１アーム部４１１ａとの間には、回転軸３９ａが挿通され、回転をスムース行わせるためのにスペーサ３９ｂが配置されている。
第２アーム部４１１ｂの先端部、すなわち第１のアーム体４１の他端側に、第１の取付軸４３が挿通される第１の挿通孔４１３が形成されている。
また、第２アーム部４１１ｂの長手方向の略中央部で扉本体２の裏面と対向する内側壁には、円柱状をなす連結竿４７の一端部を収容し固定するための円弧状の取付溝４１４が形成されている。
連結竿４７は、その一端部が取付溝４１４に半分だけ収容された状態で、円弧状をなす取付ブラケット４７１で押さえるようにして、取付ブラケット４７１を第２アーム部４１１ｂの内側壁にネジ４７２，４７３により固定することにより、第１のアーム体４１に対して固定される。
また、図３（Ａ）に示すように、第１アーム部４１１ａの長手方向略中央部で外側よりに第１のサブアーム体５の一端を取り付けるための取付孔４１５が形成されている。
【００２９】
このように、第１のアーム体４１は、一端側が支柱３ａに回転可能に取り付けられ、他端側が第１の挿通孔４１３を上方から挿通させた第２の取付軸４３の一端側が第１の取付部４３に螺合されて、枠体としての支柱３ａと扉本体２に対して回転可能に取り付けられる。
【００３０】
上述したように、第２のアーム体４４も第１のアーム体と同様の構成を有し、同様の取り付け構造をもって一端側が支柱３ａに回転可能に取り付けられ、他端側が第２の挿通孔（４４３）を上方から挿通させた第２の取付軸４６の一端側が第２の取付部４５に螺合されて、枠体としての支柱３ａと扉本体２に対して回転可能に取り付けられる。
【００３１】
そして、第１のアーム対４１と第２のアーム対４４とは、連結竿４７で連結しており、第１のアーム対４１と第２のアーム対４４とは、扉開閉時に一体的に回転することから、スムースで安定した開閉動作を実現でき、また、強度の面でも十分な強度を保つことが可能となっている。
【００３２】
次に、第１の取付部４２の具体的な構成および機能について説明する。
【００３３】
図４（Ａ）は第１の取付部４２の正面図、図４（Ｂ）は第１の取付部４２の側面図、図４（Ｃ）は第１の取付部４２の底面図である。また、図５は第１の取付部４２の第１のアーム体を取付状態時の一部切欠側面図である。
【００３４】
第１の取付部４２は、扉本体２の裏面側の所定の位置に４つのネジ２２〜２５により固定されるスライドベース４２１と、スライドベース４２１が扉本体２の裏面側に固定された状態で、第１のアーム体４１の第１の挿通孔４１３を上方（扉本体２の天井Ｃ側）から挿通され、第１の取付軸４３の一端部に形成された雄ねじ４３１が螺合可能な雌ねじ部を有し、スライドベース４２１を第１の取付軸４３の軸方向に対して略直交する方向、すなわち扉の横幅方向（左右方向）にスライド可能に配置されたスライド部４２２と、スライド部４２２のスライドベース４２１上のスライド位置を調整可能な調整部４２３と、を主構成要素として有している。
【００３５】
図６（Ａ）〜（Ｃ）は、スライドベース４２１の構成例を説明するための図であって、図６（Ａ）は上面図、図６（Ｂ）は長手方向の側面図、図６（Ｃ）は長手方向に直交する側の側面図である。
【００３６】
図６（Ａ）〜（Ｃ）に示すように、スライドベース４２１は、スライド部４２２が跨ぐようにして長手方向にスライドさせるように、いわゆる下面側が開放された中空のレール状（箱状）に形成されたガイド部４２１ａと、ガイド部４２１ａの長手方向の両側部の下端部に延設され、扉本体２に対してネジ２２〜２４により固定するためのネジ穴２４１１〜２４１４が形成された鍔部４２１ｂ，４２１ｃを有する。
そして、ガイド部４２１ａの内中空部４２１ａ−１は、後述するように略板状をなす調整部４２３がスライド可能な大きさを有するように形成されている。そして、図３（Ｂ）に示すように、長手方向に直交する側の一側面には、後述する調整ネジのネジ部が挿入され、頭部が回転可能に係合させる調整孔２４１５が形成されている。
また、ガイド部４２１ａの上面には、スライド部４２２のスライド範囲を規制するための長孔４２１６が形成されている。
【００３７】
図７（Ａ）〜（Ｄ）は、スライド部４２２の構成例を説明するための図であって、図７（Ａ）は上面図、図７（Ｂ）は長手方向の一部切欠側面図、図７（Ｃ）は長手方向に直交する側の側面図、図７（Ｄ）は底面図である。
【００３８】
スライド部４２２は、底面側にスライドベース４２１のガイド部４２１ａを跨ぐように装着可能な被ガイド部４２２ａが形成されている。
スライド部４２２の上面の中央部で、長手方向に直交する方向に第１の取付軸４３が挿入される挿入部４２２１と、第１の取付軸４３の一端部に形成された雄ねじ部４３１が螺合可能な雌ねじ部を有る図８に示すようなアウトサートナット４２２ｂが収容されるナット収容部４２２２を有する挿入螺合取付部４２２ｃが形成されている。
なお、挿入螺合取付部４２２ｃにアウトサートナット４２２ｂが収容されるナット収容部４２２２を形成した例を示しているが、この収容部の位置に第１の取付軸４３の一端部に形成された雄ねじ４３１が螺合可能な雌ねじ部を形成することも可能である。ただし、アウトサートナット４２２ｂを採用した方が蝶番４の汎用性が高くなる。
また、挿入螺合取付部４２２ｃの中央部の両側近傍には、スライドベース４２１の内中空部にスライド可能に配置される調整部４２３と、図４（Ａ），（Ｂ）に示すように、ネジ４２４，４２５で長孔４２１６を通して連結固定するためのネジ穴４２２３，４２２４が形成されている。
【００３９】
図９（Ａ）〜（Ｃ）は調整部４２３の構成例を説明するための図であって、図９（Ａ）は上面図、図９（Ｂ）は長手方向の一部切欠側面図、図９（Ｃ）は長手方向に直交する側の側面図である。
【００４０】
調整部４２３は、図９（Ａ），（Ｂ）に示すように、一端部が略直角をなすように形成された略Ｌ字状の調整板であり、上面部４２３ａには、ネジ４２４，４２５で長孔４２１６を通してスライド部４２２と連結固定するための雌ねじ４２３１，４２３２が形成されている。
調整部４２３の一端側部４２３ｂには、調整ネジ４２６（図４（Ａ）〜（Ｃ）参照）の一端側が挿通する挿通孔４２３３が形成され、かつ挿通孔４２３３と軸を一致させるようにして固定され、調整ネジ４２６の雄ねじ部が螺合される雌ねじ部を有するナット４２３ｃが固定されている。
【００４１】
以上の構成を有する第１の取付部４２の組み立ては、たとえば以下のようにして行われる。
まず、図４（Ｃ）に示すように、スライドベース４２１のガイド４２１ａ内に形成された中空部４２１ａ−１に対して板状の調整部４２３を、ナット４２３ｃがスライドベース４２１のねじ穴４２１５と対向するようにスライド可能に収容する。
この状態で、たとえば調整ねじ４２６をその一端側からスライドベース４２１のねじ穴４２１５に挿入し、調整部４２３のナット４２３ｃに対して螺合させる。
そして、スライドベース４２１のガイド部４２１ａに対してスライド部４２２の被ガイド部４２２ａを跨ぐようにして載置し、この状態でネジ４２４，４２５を長孔４２１６を通して調整部４２３の上面４２３ａに形成された雌ねじ４２３１，４２３２に対して螺合させて、スライド部４２２と調整部４２３とを連結固定する。
これにより、スライド部４２２と調整部４２３が略所定の位置に配置される。この場合、スライド部４２２と調整部４２３はスライドベース４２１の長穴４２１６を通して連結固定されることから、長穴４２１６により規制された範囲内で、スライド部４２１のガイド部４２１ａに沿ってスライド可能となっている。
そして、扉本体２の所定の位置に形成した図示しない４つの雌ねじに対して、スライドベース４２１の鍔部４２１ｂ，４２１に形成されたネジ穴２４１１〜２４１４を通して螺合して、第１の取付部４２を扉本体２の所定の位置に固定する。
【００４２】
このように組み立てられた第１および第２の取付部４２，４５は、調整ねじ４２６の雄ねじ部と調整部４２３のナット４２３ｃの螺合状態を調整するこにより、調整部４２３は、スライドベース４２１の中空部４２１ａ−１を扉本体２の横幅方向（左右方向）にスライドし、これに伴い、調整部４２３と連結固定されているスライド部４２２も同様に扉本体２の横幅方向（左右方向）にスライドする。
【００４３】
扉本体２の横幅方向（左右方向）にスライド可能に配置されたスライド部４２２と、スライド部４２２のスライドベース４２１上のスライド位置を調整可能な調整部４２３と、を主構成要素として有している。
【００４４】
上述したように、第２の取付部４５が上述したように第１の取付部４２と同様の構成を有し、同様に組み立てられて、扉本体２の所定の位置に固定される。
【００４５】
第１の取付軸４３および第２の取付軸４６は一端部に上述した第１および第２の取付部４２，４５のアウトサートナット４２２ｂに螺合可能な雄ねじ部が形成された、たとえばボルトにより構成される。
第１の取付軸４３および第２の取付軸４６は、第１および第２のアーム体４１，４４の第１の挿通孔４１３，４４３を上方（扉本体２の天井Ｃ側）から挿通され、第１および第２の取付軸４３，４６の一端部に形成された雄ねじ４３１が第１および第２の取付部４２，４５のアウトサートナット４２２ｂに螺合されて状態で、頭部は第１および第２のアーム体４１，４４の第１の挿通孔４１３，４４３を上方側に位置し第１および第２のアーム体４１，４４と係合した状態となる。
第１の取付軸４３および第２の取付軸４６は、その雄ねじ４３１の第１および第２の取付部４２，４５のアウトサートナット４２２ｂに螺合状態を調整することにより、扉本体の高さ方向（上下方向）の微調整が可能となっている。
【００４６】
第１のサブアーム体５は、図１（Ａ）に示すように、一端側が第１のアーム体４１に形成された取付孔４１５に回転可能に取り付けられ、他端部が両端部が支柱３ａ，３ｂに固定されたサブアーム取付部７の下面７１側の略中央部に、位置調整可能なブラケット５１を介して回転可能に取り付けられている。
また、第１のサブアーム体５は、ガススプリング５２を有する。
【００４７】
第２のサブアーム体６は、図１（Ａ）に示すように、一端側が両端部が支柱３ａ，３ｂに固定されたサブアーム取付部７の上面７２側の略中央部で、第１のサブアーム体５の取り付け位置より支柱３ａよりに回転転可能に取り付けられ、他端部が支柱３ｂの近傍の扉本体２の裏面側に位置調整可能なブラケット６１を介して回転可能に取り付けられている。
【００４８】
次に、上記構成を有する蝶番部４を用いて扉本体２を枠体としての支柱３ａに取り付ける作業は、たとえば以下のようにして行われる。なお、以下の説明では、第１のサブアーム体５と第２のサブアーム体６についての説明は、理解を容易にするために省略する。
【００４９】
たとえば、上述したように組み立てられた第１の取付部４２と第２の取付部４５とを、扉本体２の所定の位置に形成した図示しない４つの雌ねじに対して、スライドベース４２１の鍔部４２１ｂ，４２１に形成されたネジ穴２４１１〜２４１４を通して螺合して、第１の取付部４２を扉本体２の所定の位置に固定する。
【００５０】
次に、第１のアーム体４１を、支柱３ａの第１の位置に取り付けられた取付ブラケット３９−１に対して回転可能に軸支するための回転孔４１２に対して回転軸３９ａを挿通し、その両端を取付ブラケット３９−１内でナット等により固定する。このとき、回転をスムース行わせるために、取付ブラケット３９−１と第１のアーム体４１の一端側との間にスペーサ３９ｂを配置する。
同様に、第１のアーム体４４を、支柱３ａの第２の位置に取り付けられた取付ブラケット３９−１に対して回転可能に軸支するための回転孔４１２に対して回転軸３９ａを挿通し、その両端を取付ブラケット３９−１内でナット等により固定する。このとき、回転をスムース行わせるために、取付ブラケット３９−１と第２のアーム体の一端側との間にスペーサ３９ｂを配置する。
この第１および第２のアーム体４１，４４の一端側を回転可能に取り付け作業が回転軸を回転孔に通し、スペーサを介してナットで取付ブラケットに対して固定するだけであることから、極めて簡単に終了する。
【００５１】
次に、扉本体２の裏面側に取り付けた第１の取付部４２と第２の取付部４５の挿入螺合取付部４２２ｃの挿入部４２２１と、第１のアーム体４１と第２のアーム体４４の他端側に形成した第１の挿通孔４１３と第２の挿通孔（４４３）とが略対向するような位置に、扉本体２を仮に位置させる。
この状態で、第１の取付軸４３および第２の取付軸４６を、第１および第２のアーム体４１，４４の第１の挿通孔４１３，４４３を上方（扉本体２の天井Ｃ側）から挿通させ、第１および第２の取付軸４３，４６の一端部に形成された雄ねじ４３１を第１および第２の取付部４２，４５のアウトサートナット４２２ｂに螺合させる。このとき、第１の取付軸４３および第２の取付軸４６の頭部は第１および第２のアーム体４１，４４の第１の挿通孔４１３，４４３を上方側に位置し第１および第２のアーム体４１，４４と係合した状態となる。
【００５２】
すなわち、扉本体２を、仮位置に位置させた状態で、第１の取付軸４３および第２の取付軸４６を、第１および第２のアーム体４１，４４の第１の挿通孔４１３，４４３を上方（扉本体２の天井Ｃ側）から挿通させ、第１および第２の取付軸４３，４６の一端部に形成された雄ねじ４３１を第１および第２の取付部４２，４５のアウトサートナット４２２ｂに螺合させただけで、扉本体２を枠体として支柱３ａに対して極めて容易に取り付けることが可能である。
【００５３】
このように取り付けた扉の位置調整については、次のように行う。
扉本体２の高さ方向（上下方向）の微調整については、第１の取付軸４３または／および第２の取付軸４６の頭部をスパナ等を用いて所望の方向に回転させて、第１の取付軸４３および第２の取付軸４６の雄ねじ４３１と第１および第２の取付部４２，４５のアウトサートナット４２２ｂの雌ねじ部と螺合状態を調整することにより容易に行われる。
【００５４】
また、扉本体２の横幅方向（左右方向）の微調整は、第１の取付部４２または／および第２の取付部４５において、調整ねじ４２６の雄ねじ部と調整部４２３のナット４２３ｃの螺合状態を調整するこにより、調整部４２３をスライドベース４２１の中空部４２１ａ−１内を扉本体２の横幅方向（左右方向）にスライドさせる。
これにより、調整部４２３と連結固定されているスライド部４２２も同様に扉本体２の横幅方向（左右方向）にスライドし、スライド部４２２に第１の取付軸４３と第２の取付軸４６と螺合状態をもって第１のアーム体４１、第２のアーム体４４が取り付けられていることから、扉本体２の横幅方向（左右方向）の微調整を容易に行うことができる。
【００５５】
以上説明したように、本実施形態によれば、蝶番部４が、所定長さを有し、一端側が支柱３ａの第２側部３２ａの第１の位置に形成された取付ブラケット３９−１に回転可能に取り付けられ、他端側に長手方向に対して略直交する方向に第１の挿通孔が形成された第１のアーム体４１と、第１のアーム体４１の他端側の下方近傍の扉本体２に固定された第１の取付部４２と、第１のアーム体の第１の挿通孔を一端側から挿通された状態で当該一端側が第１の取付部４２の所定の位置に螺合され、他端側が第１のアーム体４１に対して第１の挿通孔を中心に回転可能に係合されている第１の取付軸４３と、所定長さを有し、一端側が支柱３ａの第２側部３２ａの第２の位置に形成された取付ブラケット３９−２に回転可能に取り付けられ、他端側に長手方向に対して略直交する方向に第２の挿通孔が形成された第２のアーム体４４と、第２のアーム体４４の他端側の下方近傍の扉本体２に固定された第２の取付部４５と、第２のアーム体４４の第２の挿通孔を一端側から挿通された状態で当該一端側が第２の取付部の所定の位置に螺合され、他端側が第２のアーム体４４に対して第２の挿通孔を中心に回転可能に係合されている第２の取付軸４６と、第１のアーム体４１の長手方向中央部と第２のアーム体４４の長手方向中央部とを連結する連結竿４７と、を有することから、以下の効果を得ることができる。
【００５６】
スィング仕様の比較的大型で重量のある扉の場合には、取り付け作業を細心の注意を払いながら行う必要がなく、仮位置に配置しておいて、容易に取り付けることが可能となる。
また、取り付けを無理な姿勢で細心の注意を払いながら行う必要がなく、熟練を要することなく、扉の上下、左右方向の微調整を容易に行うことができるという利点がある。
また、第１のアーム対４１と第２のアーム対４４とは、連結竿４７で連結することから、第１のアーム対４１と第２のアーム対４４とは、扉開閉時に一体的に回転する。したがって、スムースで安定した開閉動作を実現でき、また、強度の面でも十分な強度を保つことが可能である。
【００５７】
なお、アーム体の長さは本実施形態に限定されるものではなく、仕様に応じた長さを適宜選択することが可能である。
また、たとえば短尺なアーム体を構成し、回転孔と挿通孔と共有させて、取付軸で扉本体に取り付けた取付部に螺合して取り付けるように構成することも可能である。
【００５８】
また、本実施形態では、枠体としての支柱３ａに扉本体２を蝶番部４を介して取り付ける場合を例に説明したが、本発明は、たとえば図１０（Ａ），（Ｂ）、並びに、図１１（Ａ）〜（Ｃ）に示すように、キャビネットの内側壁８ａ，８ｂを枠体として扉本体２を蝶番部４を介して取り付ける等、仕様に応じた適用が可能である。
【００５９】
【発明の効果】
以上説明したように、本発明によれば、扉の大きさにかかわらず、細心の注意を払うことなく容易に取り付けることが可能である。
また、無理な姿勢をしいることなく、また熟練を要することなく、扉の上下、左右方向の微調整を容易に行うことが可能となる利点がある。
