Description

【０００１】
【発明の属する技術分野】
本発明は、左右縦框および上下框で組まれた框内に鏡板を配してなる扉およびその製造方法に関する。
【０００２】
【従来の技術】
従来の扉は、左右縦框および上下框を枠状に框組みし、各框の内周に沿って形成されている凹溝に鏡板の四周縁の凸部を嵌合固定した構成を有しており（下記特許文献１参照）、このような構成の扉を製造するには、左右縦框間に上下框のいずれか一方を固定して得られた三方枠の内周縁に沿って連続している凹溝に鏡板の凸部を嵌合固定した後、他方の横框の凹溝に鏡板凸部を嵌合させることにより該横框を固定して、框形成している。

また、下記特許文献２には、あらかじめ裏面側にＶ溝を形成した基板を準備し、この基板をＶ溝部分で折り曲げて鉄骨などの基柱に巻き付けるようにした技術が開示されている。基板の両端表面側には切り欠き段部が形成され、Ｖ溝部分で折り曲げて柱を形成したときにこれら両端の切り欠き段部同士が相対して凹溝となり、この凹溝にパネルの端部が嵌合固定される。

【０００６】
【発明が解決しようとする課題】
上記特許文献１に記載のような従来の扉構成によると、三方枠の開口側から鏡板の凸部を三方枠内周縁の凹溝に挿入し、相対的にずらしながら嵌合させていかなければならないため、寸法精度や製造条件などの管理を十分に行わないと、鏡板を相対的にずらし移動させていく途中で、縦框、横框および／または鏡板の表面に貼着した化粧シートが剥がれ（めくれ）るおそれがあった。これらの部材に貼着した化粧シートが剥がれ（めくれ）ると、部材の生地が露出し、外観上見苦しくなるばかりでなく、木材の吸放湿に伴う寸法変化が大きくなるなど品質上も好ましくない。
【０００７】
上記特許文献２に記載の技術は柱に関するもので、扉に関するものではないことに加えて、Ｖ溝部分で折り曲げた基板両端面の間にパネル端部を挟む構造であるためパネル端部が嵌合される深さ寸法が制限され、パネルの反りや振動などによって外れるおそれがある。したがって、この技術を、扉において鏡板を嵌合する構造に応用するには不安が大きい。
【０００８】
【課題を解決するための手段】
そこで本発明は、上記問題を解決し、扉製造工程中に框や鏡板の表面に貼着した化粧材が剥がれることがなく、また、鏡板を框組内に嵌合固定して扉を製造した後には各部材の反りや振動などによっても鏡板が外れにくい新規な構成の扉を提供すること、および、そのような構成の扉の製造方法を提供することを目的とする。
【０００９】
この目的を達成するため、請求項１にかかる本発明は、左右縦框および上下框を枠状に框組みし、この框内に鏡板の四周縁部を嵌合固定してなる扉において、左右縦框および上下框の各框が、芯材と、芯材の少なくとも表裏面を被覆するとともに芯材の内周面を越えてさらに内周方向に延長し且つその延長先端から内方に鉤形に折り返されて一対の略平行な折り返し部を有する表面材とからなり、表面材の一対の略平行な折り返し部の間に鏡板の周縁部が挟持固定されており、各框の表面材は、基材と、該基材の一面に貼着される化粧シートとからなり、表面材の少なくとも一端には長手方向略全長に亘って延長するＶ溝が化粧シートの反対側から形成されて表面材を折り曲げ可能としており、表面材をＶ溝部分で折り返して接着することにより前記折り返し部を形成していることを特徴としている。
【００１１】
請求項２にかかる本発明は、枠状の芯材と、芯材の開口部に配置される鏡板と、芯材の表裏面を被う左右縦框用表面材および上下框用表面材とからなり、左右縦框用表面材および上下框用表面材は芯材の内周面を越えてさらに内周方向に延長し且つその延長先端から内方に折り返されて一対の略平行な折り返し部を有しており、また、左右縦框用表面材および上下框用表面材は、板状の基材と、該基材の一面に貼着される化粧シートとからなり、且つ、表面材の少なくとも一端には長手方向略全長に亘って延長するＶ溝が化粧シートの反対側から形成されて表面材を折り曲げ可能としており、表面材をＶ溝部分で折り返して接着することにより、芯材の開口部に臨んで前記一対の略平行な折り返し部が形成され、該一対の略平行な折り返し部の間に鏡板の周縁部が挟持固定されることを特徴とする扉である。
【００１２】
請求項３にかかる本発明は、基材と、基材の一面に貼着される化粧シートとからなり、且つ、その少なくとも一端に長手方向略全長に亘って延長するＶ溝が化粧シートの反対側から形成されてＶ溝部分で折り曲げ可能とされた表面材を左右縦框および上下框の各框ごとに用意し、これらの表面材を各々Ｖ溝部分で折り返して接着することにより長手方向に延長する側縁に沿って折り返し部を有するものとし、これらの表面材を左右および上下に配置して枠組み固定し、中央に開口部を残して枠組み形成された芯材を表面材の枠組上に載置固定し、このときに表面材に形成した折り返し部が芯材の中央開口部に突出した状態とし、この芯材の中央開口部に鏡板を嵌合してその周縁部を該表面材の折り返し部上に載置し、次いで、この芯材の上に表面材を貼着して、芯材の上下に配された表面材の折り返し部の間に鏡板の周縁部を挟持固定することを特徴とする扉の製造方法である。
【００１３】
請求項４にかかる本発明は、基材と、基材の一面に貼着される化粧シートとからなり、且つ、その両端に長手方向略全長に亘って延長するＶ溝が化粧シートの反対側から形成されてＶ溝部分で折り曲げ可能とされた表面材を左右縦框および上下框のいずれか一方の各框ごとに用意し、一方、基材と、基材の一面に貼着される化粧シートとからなり、且つ、その少なくとも一端に長手方向略全長に亘って延長するＶ溝が化粧シートの反対側から形成されてＶ溝部分で折り曲げ可能とされた表面材を左右縦框および上下框の他方の各框ごとに用意し、これらの表面材を各々Ｖ溝部分で折り返して接着することにより長手方向に延長する側縁に沿って折り返し部を有するものとし、これらの表面材を左右および上下に配置して枠組み固定し、中央に開口部を残して枠組み形成された芯材を表面材の枠組上に載置固定し、このときに表面材に形成した折り返し部が芯材の中央開口部に突出した状態とし、この芯材の中央開口部に鏡板を嵌合してその周縁部を該表面材の折り返し部上に載置し、次いで、折り返し部を両端に有する表面材が芯材の下に配されている場合には該表面材を芯材の外周面に沿って折り曲げることにより芯材上に貼着するとともに、折り返し部を一端に有する表面材が芯材の下に配されている場合には該表面材とは別に用意された折り返し部を一端に有する表面材を該折り返し部が中央開口部側となるように芯材上に貼着して、芯材の上下に配された表面材の折り返し部の間に鏡板の周縁部を挟持固定することを特徴とする扉の製造方法。
【００１４】
【発明の実施の形態】
図１ないし図３を参照して本発明の一実施形態による扉の構成について説明する。
【００１５】
この扉１０は、左右縦框１１，１２および上下框１３，１４を枠状に框組みし、この框内に鏡板１５の四周縁部を嵌合固定してなる（図１）。
【００１６】
左縦框１１は、芯材１１１と、芯材１１１の表裏面および外周面を被覆する左縦框用表面材１１２とからなる。左縦框用表面材１１２の両端は、芯材１１１の内周面１１１ａを越えてさらに内周方向（右方向）に延長し且つその延長先端から内方に鉤形に折り返されて一対の垂直部１１２ａ，１１２ａおよび一対の略平行な折り返し部１１２ｂ，１１２ｂを形成している（図２）。
【００１７】
左縦框用表面材１１２は、図４に示す縦框表面材用化粧板１６から形成される。この縦框用化粧板１６は、板状の基材１６１の一面に化粧シート１６２が貼着されたものであり、基材１６１の両端にはそれぞれ２つのＶ溝１６３ａ，１６３ｂが、また中央には２つのＵ溝１６４，１６４が、いずれも化粧シート１６２の反対側から刻設形成されている。これらＶ溝およびＵ溝は、化粧シート１６２に略達する深さに形成されるか、あるいは、該Ｖ溝・Ｕ溝部分での折り曲げを可能にするわずかな厚さを基材１６１に残すような深さに形成される。Ｖ溝１６３ａ，１６３ｂの角度はいずれも９０度であり、これらＶ溝部分で順次折り曲げて接着固定することにより、Ｖ溝１６３ａ，１６３ｂ間の部分が垂直部１１２ａとなり、Ｖ溝１６３ａより端部側が折り返し部１１２ｂとなる。Ｕ溝１６４，１６４は芯材１１１の厚さに相当する間隔で形成されており、これらＵ溝部分で折り曲げて接着固定することにより、Ｖ溝１６３ｂとＵ溝１６４との間の部分が芯材１１１の表裏を被覆する部分１１２ｃ，１１２ｄとなり、Ｕ溝１６４，１６４間の部分が芯材１１１の外周面を被覆する部分１１２ｅとなる。
【００１８】
右縦框１２は、左縦框１１と対称的な構成を有している。すなわち、右縦框１２は、芯材１２１と、芯材１２１の表裏面および外周面を被覆する右縦框用表面材１２２とからなり、その両端は、芯材１２１の内周面１２１ａを越えてさらに内周方向（左方向）に延長し且つその延長先端から内方に鉤形に折り返されて一対の垂直部１２２ａ，１２２ａおよび一対の略平行な折り返し部１２２ｂ，１２２ｂを形成している（図２）。
【００１９】
右縦框用表面材１２２も、左縦框用表面材１１２と同様に、図４に示す縦框表面材用化粧板１６から形成される。Ｖ溝１６３ａ，１６３部分で順次折り曲げて接着固定することにより、Ｖ溝１６３ａ，１６３ｂ間の部分が垂直部１２２ａとなり、Ｖ溝１６３ａより端部側が折り返し部１２２ｂとなる。また、Ｕ溝１６４，１６４部分で折り曲げて接着固定することにより、Ｖ溝１６３ｂとＵ溝１６４との間の部分が芯材１２１の表裏を被覆する部分１２２ｃ，１２２ｄとなり、Ｕ溝１６４，１６４間の部分が芯材１１１の外周面を被覆する部分１２２ｅとなる。
【００２０】
上框１３は、芯材１３１と、芯材１３１の表裏面をそれぞれ被覆する上框用表面材１３２，１３３とからなる。芯材１３１の表面１３１ｂを被覆する上框用表面材１３２は、芯材１３１の内周面１３１ａを越えてさらに内周方向（下方）に延長し且つその延長先端から内方に鉤形に折り返されて垂直部１３２ａおよび折り返し部１３２ｂを形成している（図３）。同様に、芯材１３１の裏面１３１ｃを被覆する上框用表面材１３３は、芯材１３１の内周面１３１ａを越えてさらに内周方向（下方）に延長し且つその延長先端から内方に鉤形に折り返されて垂直部１３３ａおよび折り返し部１３３ｂを形成している（図３）。折り返し部１３２ｂ，１３３ｂは略平行である。
【００２１】
上框用表面材１３２，１３３は、図５に示す横框表面材用化粧板１７から形成される。この縦框用化粧板１７は、板状の基材１７１の一面に化粧シート１７２が貼着されたものであり、基材１６１の一端には２つのＶ溝１７３ａ，１７３ｂが化粧シート１７２の反対側から刻設形成されている。これらＶ溝は、化粧シート１７２に略達する深さに形成されるか、あるいは、該Ｖ溝部分での折り曲げを可能にするわずかな厚さを基材１７１に残すような深さに形成される。Ｖ溝１７３ａ，１７３ｂの角度はいずれも９０度であり、これらＶ溝部分で順次折り曲げて接着固定することにより、Ｖ溝１７３ａ，１７３ｂ間の部分が垂直部１３２ａ，１３３ａとなり、Ｖ溝１７３ａより端部側が折り返し部１３２ｂ，１３３ｂとなる。Ｖ溝１７３ｂと反対側端部の間が芯材１３１の表裏面１３１ｂ，１３１ｃを被覆する部分１３２ｃ，１３３ｃとなる。
【００２２】
下框１４は、上框１３と対称的な構成を有している。すなわち、芯材１４１と、芯材１４１の表裏面をそれぞれ被覆する下框用表面材１４２，１４３とからなる。下框用表面材１４２は、芯材１４１の内周面１４１ａを越えてさらに内周方向（上方）に延長し且つその延長先端から内方に鉤形に折り返されて垂直部１４２ａおよび折り返し部１４２ｂを形成している（図３）。同様に、下框用表面材１４３は、芯材１４１の内周面１４１ａを越えてさらに内周方向（上方）に延長し且つその延長先端から内方に鉤形に折り返されて垂直部１４３ａおよび折り返し部１４３ｂを形成している（図３）。折り返し部１４２ｂ，１４３ｂは略平行である。
【００２３】
下框用表面材１４２，１４３も、上框用表面材１３２，１３３と同様に、図５に示す横框表面材用化粧板１７から形成される。Ｖ溝１７３ａ，１７３ｂ溝部分で順次折り曲げて接着固定することにより、Ｖ溝１７３ａ，１７３ｂ間の部分が垂直部１４２ａ，１４３ａとなり、Ｖ溝１７３ａより端部側が折り返し部１４２ｂ，１４３ｂとなり、Ｖ溝１７３ｂと反対側端部の間が芯材１４１の表裏面１４１ｂ，１４１ｃを被覆する部分１４２ｃ，１４３ｃとなる。
【００２４】
左右縦框１１，１２の芯材１１１，１２１および上下横框１３，１４の芯材１３１，１４１としては、合板、木質繊維板（ＭＤＦなど）、木削片板、単板積層板などの木質系が好適に用いられる。これら芯材の厚みは扉１０の用途や施工条件などにより適宜選択可能であるが、たとえば２０〜５０ｍｍ程度の範囲とすることができる。
【００２５】
図４に示す縦框表面材用化粧板１６の基材１６１および図５に示す横框表面材用化粧板１７の基材１７１としては、その一面に化粧シートを貼着することができるものであれば特に限定されないが、合板、木質繊維板（ＭＤＦなど）、木削片板、単板積層板などの木質系、スチロール樹脂板、塩化ビニル樹脂板、強化プラスチック板、発泡スチロール樹脂板、発泡ウレタン樹脂板などの合成樹脂系、あるいは木質系や合成樹脂系の複合積層板などを使用することができる。基材１６１，１７１の厚みは扉１０の用途や施工条件などにより適宜選択可能であるが、たとえば３〜６ｍｍ程度の範囲とすることができる。
【００２６】
これら化粧板１６，１７の化粧シート１６２，１７２としては、たとえば天然木材を切削して得られる天然突板、人工突板、不織布、紙、合成樹脂シートなどを用いることができ、可撓性を有する材料から形成したシートに各種模様を印刷したものを使用してもよい。化粧シート１６２，１７２として好適な合成樹脂シートとしては、たとえばオレフィン樹脂、塩化ビニル樹脂、ポリエステル樹脂、アクリル樹脂などのシートが挙げられる。また、これら合成樹脂シートの間に紙を挟んで圧着した複合シートや、合成樹脂を含浸させた含浸紙なども化粧シート１６２，１７２として用いることができる。これらの化粧シート１６２，１７２に上塗りを施してもよい。化粧シート１６２，１７２の厚みは、たとえば０．０５〜１ｍｍ程度の範囲から選択することができる。なお、化粧シートに代えて、基材に表面塗装を施して化粧層を形成してもよい。
【００２７】
このような化粧シート１６２，１７２を、接着剤、たとえば酢酸ビニル樹脂などの熱可塑性樹脂に熱硬化性樹脂または尿素粉末などを混入させて耐水性向上を図ったものを用いて、基材１６１，１６２の一面に貼着した後、化粧シート貼着面とは反対側から、前述のように、化粧シート１６２，１７２に略達する深さまたはわずかな厚さを基材１６１，１７１に残すような深さに、Ｖ溝１６３ａ，１６３ｂ，１７３ａ，１７３ｂおよびＵ溝１６４，１６４を刻設して、縦框表面材用化粧板１６および横框表面材用化粧板１７を得る。
【００２８】

【００２９】
上述のような構成を有する扉１０の製造方法について、図６ないし図８を参照して説明する。
【００３０】
左縦框用表面材１１２および右縦框用表面材１２２を形成するための縦框表面材用化粧板１６（図４）各１枚を用意し、それらのＵ溝１６４，１６４にそれぞれホットメルト接着剤を充填する（図６（ａ））。ホットメルト接着剤の充填は、スチレン・ブタジエン・スチレンブロック共重合体（ＳＢＳ）、シリコン樹脂などの熱可塑性樹脂を加熱溶融させた状態でＵ溝１６４，１６４に充填するものであり、充填後も弾力性を有している。また、スチレン・ブタジエン・ラバー（ＳＢＲ）やシリコン樹脂などから円形、楕円形、多角形などの断面形状を有するように成形された棒状部材を酢酸ビニル樹脂などの軟質材用接着剤を用いてＵ溝１６４，１６４に貼着することにより充填してもよい。
【００３１】
縦框表面材用化粧板１７のＶ溝１６３ａ，１６３ｂには、充填後曲げ加工をした後に硬化する接着剤を充填する（図６（ａ））。そして、接着剤充填後、速やかにＶ溝１６３ａ，１６３ｂ部分を順次内方に折り曲げて鉤形状とし、垂直部１１２ａ，１２２ａおよび折り返し部１１２ｂ，１２２ｂを形成する（図６（ｂ））。
【００３２】
一方、上框用表面材１３２，１３３および下框用表面材１４２，１４３を形成するための横框表面材用化粧板１７（図５）を各１枚用意し、それらの１７３ａ，１７３ｂに、充填後曲げ加工をした後に硬化する接着剤を充填する（図７（ａ））。そして、接着剤充填後、速やかにＶ溝１７３ａ，１７３ｂ部分を順次内方に折り曲げて鉤形状とし、垂直部１３２ａ（１３３ａ），１４２ａ（１４３ａ）および折り返し部１３２ｂ（１３３ｂ），１４２ｂ（１４３ｂ）を形成する（図７（ｂ））。
【００３３】
このようにして形成した左縦框用表面材１１２、右縦框用表面材１２２、上框用表面材１３２，１３３のいずれか一方（図８では１３２）、下框用表面材１４２，１４３のいずれか一方（図８では１４２）をそれぞれ所定位置に配置して枠組みして接着剤にて固定した後、枠組みした表面材１１２，１２２，１３２，１４２上に、芯材１１１，１２１，１３１，１４１を枠組みした芯材枠１８を載置して接着剤にて貼着する（図８）。このとき、芯材枠１８の左右縁１８ａ，１８ｂが左右縦框用表面材１１２，１２２の内側のＵ溝１６４，１６４の中心線上に沿って配置される。また、芯材枠１８の開口縁に沿って開口部１９に突出するように、左右縦框表面材１１２，１２２および上下横框表面材１３２，１４２の垂直部分１１２ａ，１２２ａ，１３２ａ，１４２ａが突出し、それらの先端から折り返し部１１２ｂ，１２２ｂ，１３２ｂ，１４２ｂが芯材枠１８の開口縁近くに至るまで形成されていて、鏡板１５に対する載置枠を与えている。
【００３４】
そして、芯材１８の開口部１９に、枠組みした表面材１１２，１２２，１３２，１４２とは反対側から、鏡板１５を挿入し、その四周縁を、開口縁近くに突出している折り返し部１１２ｂ，１２２ｂ，１３２ｂ，１４２ｂ上に載置する。
【００３５】
そして、左縦框用表面材１１２を外側のＵ溝１６４部分で折り曲げることにより左縦框部分の芯材１１１の外周面から表面側に巻き込むように貼着するとともに、同様に、右縦框用表面材１２２を外側のＵ溝１６４部分で折り曲げることにより右縦框部分の芯材１２１の外周面から表面側に巻き込むように貼着する。これによって、垂直部１１２ａ，１２２ａおよび折り返し部１１２ｂ，１２２ｂよりなる鉤形先端部分が芯材開口部１１９に上方から入り込み、既に芯材枠１８の下方に配置されている折り返し部１１２ｂ，１２２ｂと協働して鏡板１５の左右周縁を挟持する（図２）。
【００３６】
また、上下縦框については、枠組みに用いた上下框用表面材１３２，１４２以外の上下框用表面材１３３，１４３（図７）を、枠組みに用いた上下框用表面材１３２，１４２に相対させるように芯材枠１８の上方から上框部分の芯材１３１および下框部分の芯材１４１に貼着する。これによって、垂直部１３３ａ，１４３ａおよび折り返し部１３３ｂ，１４３ｂよりなる鉤形先端部分が芯材開口部１１９に上方から入り込み、既に芯材枠１８の下方に配置されている上下框用表面材１３２，１４２の折り返し部１３２ｂ，１４２ｂと協働して鏡板１５の上下周縁を挟持する（図３）。
【００３７】
折り返し部１１２ｂ，１２２ｂ，１３３ｂ，１４３ｂにはあらかじめ接着剤が塗布されているので、上記のようにして鏡板１５の四周縁が折り返し部１１２ｂ，１１２ｂ間（左框部）、１２２ｂ，１２２ｂ間（右框部）、１３２ｂ，１３３ｂ間（上框部）および１４２ｂ，１４３ｂ間（下框部）に挟持されている状態で上から面的に加圧することにより、接着剤を硬化させ、鏡板１５を堅固に嵌合保持した扉１０を製造することができる。
【００３８】
なお、左右縦框用表面材１１２，１２２をＵ溝１６４，１６４部分で折り曲げて鉤形先端部分を開口部１９内に突入させたときに、該鉤形先端部分の長手方向両端部が上下框部分の芯材１３１，１４１と干渉しないように、該鉤形先端部分の両端部をあらかじめ切除しておく（図８）。
【００３９】
図９ないし図１１には、本発明の他の実施形態による扉の構成が示されている。この実施形態による扉１０’は、左右縦框１１’，１２’および上下框１３，１４を枠状に框組みし、この框内に鏡板１５の四周縁部を嵌合固定してなるものであり（図９）、上下框１３，１４および鏡板１５については、既述実施形態による扉１０におけると同様であるので、説明を割愛する。
【００４０】
左縦框１１’は、既述実施形態による扉１０’における左縦框１１と略同様の構成を有し、芯材１１１’と、芯材１１１’の表裏面および外周面を被覆する左縦框用表面材１１２’とからなる。
【００４１】
左縦框用表面材１１２’は、図１２に示す縦框表面材用化粧板１６’から形成される。この縦框用化粧板１６’は、板状の基材１６１’の一面に化粧シート１６２’が貼着されたものであり、基材１６１’の両端にはそれぞれ９０度のＶ溝１６３ｃ’と４５度のＶ溝１６３ａ’が隣接して形成されるとともに若干の間隔をおいてもう一つの４５度のＶ溝１６３ｂが形成され、また、中央には２つのＵ溝１６４’，１６４’が形成されている。これらＶ溝およびＵ溝はいずれも化粧シート１６２’の反対側の基材１６１’面から刻設され、化粧シート１６２’に略達する深さに形成されるか、あるいは、該Ｖ溝・Ｕ溝部分での折り曲げを可能にするわずかな厚さを基材１６１’に残すような深さに形成される。Ｖ溝１６３ｂ’，１６３ａ’，１６３ｃ’部分で順次折り曲げて接着固定することにより、Ｖ溝１６３ｂ’，１６３ａ’間の部分が傾斜部１１２ａ’となり、Ｖ溝１６３ａ’，１６３ｃ’間の部分が垂直部１１２ｂ’となり、Ｖ溝１６３ｃ’より端部側が折り返し部１１２ｃ’となる。Ｕ溝１６４’，１６４’は芯材１１１’の厚さに相当する間隔で形成されており、これらＵ溝部分で折り曲げて接着固定することにより、Ｖ溝１６３ｂ’とＵ溝１６４’との間の部分が芯材１１１’の表裏を被覆する部分（符号なし）となり、Ｕ溝１６４’，１６４’間の部分が芯材１１１’の外周面を被覆する部分（符号なし）となる（図１０）。
【００４２】
右縦框１２’は、左縦框１１’と対称の構成を有しており、芯材１２１’と、芯材１２１’の表裏面および外周面を被覆する右縦框用表面材１２２’とからなる。
【００４３】
右縦框用表面材１２２’も、左縦框用表面材１１２’と同様に、図１２に示す縦框表面材用化粧板１６’から形成される。Ｖ溝１６３ｂ’，１６３ａ’，１６３ｃ’部分で順次折り曲げて接着固定することにより、Ｖ溝１６３ｂ’，１６３ａ’間の部分が傾斜部１２２ａ’となり、Ｖ溝１６３ａ’，１６３ｃ’間の部分が垂直部１２２ｂ’となり、Ｖ溝１６３ｃ’より端部側が折り返し部１２２ｃ’となる。Ｕ溝１６４’，１６４’部分で折り曲げて接着固定することにより、Ｖ溝１６３ｂ’とＵ溝１６４’との間の部分が芯材１２１’の表裏を被覆する部分（符号なし）となり、Ｕ溝１６４’，１６４’間の部分が芯材１２１’の外周面を被覆する部分（符号なし）となる（図１０）。
【００４４】
なお、左右縦框１１’，１２’は、上記した点を除いて、既述実施形態による扉１０’における左右縦框１１，１２と実質的に同様の構成を有している。
【００４５】
この実施形態による扉１０’によれば、既述実施形態による扉１０と同様、表面材の折り返し部の間に鏡板１５の四周縁を挟持固定することができるほか、左右縦框用表面材１１２’，１２２’の両端鉤形先端部に傾斜部１１２ａ’，１２２ａ’が形成されるので、意匠性が向上するという付加的な作用効果を発揮することができる。
【００４６】
以上に本発明を図示実施形態に基づいて説明したが、本発明はこれらの実施形態に限定されるものではなく、特許請求の範囲に記載された発明の範囲内において様々な実施形態を取り得る。たとえば、図１ないし図８に示す実施形態では、左右縦框用表面材および上下横框用表面材がいずれもコの字形断面形状の鉤形先端部を有するものとして、左右縦框用表面材のコの字形先端部と上下横框用表面材のコの字形先端部とを直交させていも接ぎによる接合形態を採用している（図８）が、表面材の先端部鉤形状は、略平行に延長する一対の折り返し部間に鏡板の周縁を挟持固定できるものである限りにおいて任意であり、多角形、円弧、曲線またはこれらの組み合わせ形状を断面形状とする鉤形先端部を表面材に形成してもよい。左右縦框用表面材の鉤形先端部と上下横框用表面材の鉤形先端部との接合形態も、いも接ぎのほか、留め接ぎによるものであってもよい。

[Problems to be solved by the invention]
According to the conventional door configuration as described in Patent Document 1, the projection of the end plate is inserted into the concave groove on the inner periphery of the three-side frame from the opening side of the three-side frame, and must be fitted while being relatively displaced. Therefore, if the dimensional accuracy and manufacturing conditions are not sufficiently controlled, the decorative sheet attached to the surface of the downspout, recumbent and / or end plate will be peeled off while the end plate is relatively shifted and moved. There was a risk of turning. If the decorative sheets attached to these members are peeled off (turned over), the material of the members is exposed and not only looks unsightly but also unfavorable in terms of quality, such as a large dimensional change associated with moisture absorption and desorption of wood. .
