【発明の属する技術分野】
本発明はドアの外周部を構成する縦框材と横框材とを直角に接合してなるドア構造に関する。
【０００２】
【背景の技術】
住宅等の建物の開口部を開閉するドアとして、縦框材と横框材とを矩形枠状に組立て、この矩形枠の内側に面材（鏡板）をはめ込む形式のドアが知られている。このようなドアの一例として、特許文献１に記載のものが知られている。この特許文献１では縦框材と横框材とを矩形枠状に組立てるとともに、縦框材と横框材に連なる嵌合孔を形成し、該嵌合孔に跨り嵌入されるやといざねをもって結合一体化せしめることで、縦框材と横框材とを接合している。

【０００４】
【発明が解決しようとする課題】
ところで、上記のドアでは、縦框材と横框材とはそれぞれ合板や角材等の中実な材料で形成されている。そこで、材料コストや框材の重量軽減を目的として、縦框材および横框材を、例えば樹脂による押出成形で中空に形成することが考えられるが、この場合、縦框材と横框材に連なる嵌合孔を形成した場合、框材が中空であるので、嵌合孔の深さが浅くなって十分でなく、このため、やといざねが嵌合孔にしっかりと嵌入できず、よって、縦框材と横框材とを確実に接合し難いという問題ある。
【０００５】
本発明は上記事情に鑑みてなされたもので、中空の縦框材と横框材とを確実に接合することができるドア構造を提供することを課題としている。
【０００６】
【課題を解決するための手段】
上記課題を解決するために、請求項１に記載の発明は、例えば図１〜図６に示すように、ドア１の外周部を構成する縦框材２と横框材３とを直角に接合してなるドア構造であって、
前記縦框材２と横框材３とはそれぞれ内部に、框材２，３の長手方向に沿って長尺な中空部２ａ，３ａを有しており、
前記縦框材２と横框材３とのうちの一方の框材（例えば横框材３）の端面が、他方の框材（例えば縦框材２）の端部側面に接合部材６を介して接合されており、
前記接合部材６は、基板７と、この基板７の一方の面に設けられた嵌合部８，９と、前記基板７の他方の面に設けられた係止部１１，１１とを備え、
前記基板１１は、一方の框材３の端面と他方の框材２の端部側面とに挟まれた状態でこれらに当接しており、前記嵌合部８，９は前記一方の框材３の端面から中空部３ａ，３ａに挿入されて嵌合しており、前記係止部１１，１１は他方の框材２の端部側面から、この側面に形成された孔１３を通して中空部２ａに挿入されたうえで、この孔１３の縁部に係止していることを特徴とする。
【０００７】
ここで、一方の框材３を横框材、他方の框材２を縦框材とすると、框材どうしの接合は、縦框材２かちの接合となる。また、一方の框材を縦框材、他方の框材を横框材とすると、框材どうしの接合は、横框材かちの接合となる。
【０００８】
請求項１に記載の発明によれば、接合部材６の基板７が一方の框材３の端面と他方の框材２の端部側面とに挟まれた状態でこれらに当接しているで、これら框材２，３はその端面に中空部３ａが開口していても、基板７を介して安定的に互いに直角に当接される。そして、接合部材６の嵌合部８，９が中空部３ａ，３ａに挿入されて嵌合しており、係止部１１，１１が框材２の側面に形成された孔１３，１３を通して中空部２ａに挿入されたうえで、この孔１３の縁部に係止しているので、中空の縦框材２と横框材３とを容易かつ確実に接合できる。
【０００９】
請求項２に記載の発明は、請求項１に記載のドア構造において、
前記基板７の一方の面には、嵌合部８，９が複数形成されており、これら嵌合部８，９がそれぞれ前記一方の框材３の複数の中空部３ａ，３ａに挿入されて嵌合していることを特徴とする。
【００１０】
請求項２に記載の発明によれば、基板１の一方の面に形成された複数の嵌合部８，９が、一方の框材３の複数の中空部３ａ，３ａに挿入されて嵌合しているので、中空の縦框材２と横框材３とをより強固に接合できる。
【００１１】
請求項３に記載の発明は、請求項１または２に記載のドア構造において、
前記係止部１１は、弾性的に縮径した状態で前記孔１３に挿通され、孔１３から中空部２ａに至った際に弾性復帰して拡径することによって前記孔１３の縁部に係止していることを特徴とする。
【００１２】
請求項３に記載の発明によれば、接合部材６の係止部１１を他方の框材２の側面に形成された孔１３に挿入して中空部２ａに至らしめるだけて、該係止部１１を孔１３の縁部に容易に係止できる。したがって、接合部材６を他方の框材２の側面に容易に取付けることができる。
【００１３】
請求項４に記載の発明は、請求項１〜４のいずれか一項に記載のドア構造において、
前記他方の框材２の側面には、凹溝１２が框材２の長手方向に沿って形成されており、前記基板７の他方の面には、前記凹溝１２に嵌合する凸条１０が形成され、この凸条１０の先端部に前記係止部１１が形成されており、
前記凹溝１２には前記凸条１０が嵌合しており、前記係止部１１は凹溝１２の底面に形成された孔１３を通して前記中空部２ａに挿入されたうえで、この孔２ａの縁部に係止していることを特徴とする。
【００１４】
請求項４に記載の発明によれば、他方の框材２の凹溝１２に、接合部材６の凸条１０が嵌合しているので、接合部材６を他方の框材２の側面に位置決めして強固に取付けることができ、よって、接合部材６によってより強固に框材２，３どうしを接合できる。
【００１５】
請求項５に記載の発明は、請求項４に記載のドア構造において、
前記凹溝１２には、前記縦框材２と横框材３とで形成された枠体４内に設けられた面材５の縁部が挿入されていることを特徴とする。
【００１６】
ここで、前記凹溝１２は他方の框材２の側面に形成されているが、一方の框材３にも同様形状の凹溝１７を形成するのが望ましい。
【００１７】
請求項５に記載の発明によれば、他方の框材２の側面に形成された凹溝１２に、面材５の縁部が挿入されているので、この面材５を確実に保持できる。
【００１８】
請求項６に記載の発明は、請求項４に記載のドア構造において、
前記凹溝１２には、額縁材１６が挿入され、前記縦框材２と横框材２とで形成された枠体４内に設けられた面材５の縁部が前記額縁材１６によって保持されていることを特徴とする。
【００１９】
ここで、一方の框材３にも同様形状の凹溝１７を形成した場合、この凹溝１７にも額縁材１８を挿入して、この額縁材１８によっても面材５の縁部を保持するのが望ましい。
【００２０】
請求項６に記載の発明によれば、ドア１の面材５を額縁材２６を介して確実に保持でき、また框材２，３と面材５との接合部を額縁材２６によって秀麗に仕上げることができる。
【００２１】
請求項７に記載の発明は、請求項１〜６のいずれか一項に記載のドア構造において、
前記縦框材２と横框材３とは、それぞれセルロース系微粉粒と樹脂とを混合して押出成形した中空材であることを特徴とする。
【００２２】
ここで、前記セルロース系微粉粒とは、例えば、廃材等の木材の粗粉砕物、バカスの祖粉砕物、稲藁の粗粉砕物等における各種植物細胞体の原料材粗粉砕物を出発原料とし、これを磨砕処理することによって得ることができる。
【００２３】
磨砕処理とは、粉砕処理と研磨処理とを併せ持つ処理を言うものであり、これら粉砕処理と研磨処理とを同時に行う処理であっても、粉砕処理を行った後、研磨処理を行う二工程からなる処理であってもよい。すなわち、ここで言う磨砕処理とは、後述するように、粗粉砕物から微粉砕物にする粉砕処理と、微粉際された粉粒を、繊維状態のものが絡み合い、その表面が繊毛で覆われている状態の粉粒形状から、表面に繊毛が少ない状態となるように表面研磨する研磨処理とを併せた処理を指している。
【００２４】
前記セルロース系微粉粒は、上記のように磨砕処理により粒径状に形成されることで、通常の木粉のような繊毛上の突出部分が少なくなり、水（湿気を含む）や溶剤などを吸着しにくくなっている。
【００２５】
また、前記樹脂とは、硬質樹脂や軟質樹脂のことであり、塩化ビニル樹脂、発泡塩化ビニル樹脂、ポリエチレン樹脂、ポリプロピレン樹脂、フェノール樹脂、ウレタン樹脂、ポリウレタン樹脂、ＡＢＳ樹脂、ポリスチレン樹脂等が用いられるが、中でも塩化ビニル樹脂、ポリエチレン樹脂、ポリプロピレン樹脂が、成形部材を形成するには好適である。また、樹脂は廃材の樹脂から得るようにしてもよい。
【００２６】
請求項７に記載の発明によれば、框材２，３に防水性、防腐性や木質感を付与することができる。また、押出成形したものであるので、框材２，３の内部に押出成形の際に容易に中空部２ａ，３ａを形成できる。
【００２７】
【発明の実施の形態】
以下、図面を参照して本発明の実施の形態を説明する。
図１（ａ）、（ｂ）にそれぞれ示すように、本発明に係るドア構造を備えたドア１は、格子入板戸であり、２本の縦框材２と２本の横框材３とを矩形枠状に組立てた枠体４の内側に格子状に面材５をはめ込んだ構造となっている。ここで、図１（ａ）に示すドアは面材５が合板で形成されたものであり、図１（ｂ）に示すドアは面材５がガラス板で形成されたものである。
【００２８】
前記縦框材２と横框材３とは、それぞれセルロース系微粉粒と樹脂とを混合して押出成形した中空材で形成されており、内部にはそれぞれ複数の中空部２ａ…，３ａ…を有している。縦框材２と横框材３とは、縦框材２かちとなるように、直角に接合されている。つまり、縦框材２の端部側面に、横框材３の端面が接合部材６を介して接合されている。
【００２９】
接合部材６は、基板７と、この基板７の一方の面に設けられた嵌合部８，９と、基板７の他方の面に設けられた凸条１０と、この凸状１０の先端面に形成された係止部１１とを備え、これらは樹脂による一体成形によって形成されている。基板７は、図２および図４に示すように、縦長の長方形板状のものであり、その幅は縦横の框材２，３の厚さと等しくなっている。また、基板７の下端部には、後述する額縁材の端部がはめ込まれる矩形状の切欠き７ａが形成されている。
【００３０】
嵌合部８は、左右一対のプレート８ａ，８ａと、これら一対のプレート８ａ，８ａの上端部間に設けられたプレート８ｂとを備えており、左右一対のプレート８ａ，８ｂは先開き状態となっており、上側のプレート８ｂは上方に開いた状態となっている。また、これらプレート８ａ，８ａ，８ｂの先端部には、内側に傾斜する傾斜面８ｃがそれぞれ形成されている。
嵌合部９は、嵌合部８と隙間を隔ててその下方に設けられたもので、左右一対のプレート９ａ，９ａと、これら一対のプレート９ａ，９ａの下端部間に設けられたプレート９ｂとを備えており、左右一対のプレート９ａ，９ｂは先開き状態となっており、下側のプレート９ｂは下方に開いた状態となっている。また、これらプレート９ａ，９ａ，９ｂの先端部には、先端に向かうに従って漸次内側に傾斜する傾斜面９ｃがそれぞれ形成されている。
【００３１】
嵌合部８と嵌合部９とはそれぞれ、横框材３の下二つの中空部３ａ，３ａに挿入されて嵌合するものであり、嵌合部８，９間の隙間は、中空部３ａ，３ａ間の壁部３ｂの厚さとほぼ等しくなっている。また、嵌合部８，９の開いた状態における正面視における縦横の寸法は、中空部３ａ，３ａの縦横の寸法より若干大きめに設定されており、嵌合部８のプレート８ａ，８ａ，８ｂおよび嵌合部９のプレート９ａ，９ａ，９ｂは内側に弾性的に撓めるようになっている。
【００３２】
そして、嵌合部８，９を中空部３ａ，３ａに挿入する際に、嵌合部８のプレート８ａ，８ａ，８ｂおよび嵌合部９のプレート９ａ，９ａ，９ｂがそれぞれ内側に弾性的に撓み、中空部３ａ，３ａに挿入された際に、プレート８ａ，８ａ，８ｂおよびプレート９ａ，９ａ，９ｂが、その弾性復帰力によって中空部３ａ，３ａの内壁面に圧接することによって、嵌合部８，９が中空部３ａ，３ａに嵌合している。
また、プレート８ａ，８ａ，８ｂおよびプレート９ａ，９ａ，９ｂの先端部に形成されている傾斜面８ｃ，９ｃは、嵌合部８，９が中空部３ａ，３ａに挿入される際に、中空部３ａ，３ａの入口縁部によって押されて、プレート８ａ，８ａ，８ｂおよびプレート９ａ，９ａ，９ｂを内側に押圧し始める際のガイドとなる。
【００３３】
前記凸条１０は基板７の他方の面に、基板７の上端から前記嵌合部９の下端位置に対向する位置まで帯状に形成されたもので、断面矩形状に形成されている。また、凸条１０の長手方向に沿う両側面には、それぞれ細かい多数の突起が凸条１０の長手方向に延在するようにして形成されている。
一方、縦框材２の側面には凹溝１２が上下方向に沿って形成されている。この凹溝１２は接合部材６の凸条１０が嵌合するものであり、断面矩形状に形成されている。また、凹溝１２の対向する内側面には、それぞれ細かい多数の突起が凹溝１２の長手方向に延在するようにして形成されている。
そして、縦框材２の凹溝１２に、凸条１０が嵌合しており、この状態において、凹溝１２の側面の突起が、凸条１０の側面の突起間に係合することによって凹溝１２と凸条１０の嵌合が強固なものとなっている。
【００３４】
さらに、前記凸条１０の先端面には二つの係止部１１，１１が上下に所定間隔離間して設けられている。この係止部１１は、図４（ａ）、（Ｃ）に示すように４つの係止爪１１ａによって構成されており、これら係止爪１１ａは外側に向けて先開きの状態となっている。係止爪１１ａは開いた状態から内側に弾性的に撓み可能となっており、係止爪の１１ａの先端部には、先端に向かうに従って漸次内側に傾斜する傾斜面１１ｂが形成されている。
【００３５】
一方、縦框材２の凹溝１２の底面には、前記係止部１１，１１と対向して孔１３，１３が形成されている。この孔１３は縦框材２の中空部２ａに開口しており、その直径は前記係止爪１１ａ…が最も閉じた状態における係止部１１の直径より大きく、かつ係止爪１１ａ…が互いに平行となるような若干開いた状態における係止部１１の直径より小さくなっている。
そして、係止部１１は、弾性的に縮径した状態で前記孔１３に挿通され、孔１３から中空部２ａに至った際に弾性復帰して拡径することによって孔１３の縁部に係止している。
また、係止爪１１ａの先端部に形成されている傾斜面１１ｃは、係止部１１が孔１３に挿入される際に、孔１３の入口縁部によって押されて、係止爪１１ａを内側に押圧し始める、つまり、係止部１１を縮径し始める際のガイドとなる。
【００３６】
そして、縦框材２と横框材３とを接合部材６を介して直角に接合する場合、まず、横框材３の端面から中空部３ａ，３ａに接合部材６の嵌合部８，９を挿入して、中空部３ａ，３ａに嵌合するとともに、基板７を横框材３の端面に当接する。
この場合、嵌合部８，９を中空部３ａ，３ａに挿入した際に、傾斜面８ｃ，９ｃが中空部３ａ，３ａの入口縁部によって押されて、プレート８ａ，８ａ，８ｂおよびプレート９ａ，９ａ，９ｂが内側に弾性的に撓み、この状態で、嵌合部８，９を中空部３ａ，３ａに挿入していき、中空部３ａ，３ａに完全に挿入した際に、プレート８ａ，８ａ，８ｂおよびプレート９ａ，９ａ，９ｂが、その弾性復帰力によって中空部３ａ，３ａの内壁面に圧接することによって、嵌合部８，９が中空部３ａ，３ａに嵌合する。
また、プレート８ａ，８ａ，８ｂおよびプレート９ａ，９ａ，９ｂの外面には細かい突起が形成されているので、この突起は中空部３ａ，３ａの内壁面に食い込むことによって、嵌合部８，９が中空部３ａ，３ａにより確実に嵌合する。
なお、嵌合部８，９を中空部３ａ，３ａに挿入する際に、嵌合部８，９の外面または中空部３ａ，３ａの内壁面に接着剤を塗布しておき、この接着剤によって嵌合部８，９を中空部３ａ，３ａの内壁面に接着固定しもよい。
【００３７】
次に、横框材３の固定された接合部材６の凸条１０を縦框材３の凹溝１２にはめ込むとともに、接合部材６の係止部１１，１１を凹溝１２の底部に形成されている孔１３，１３に挿入して、係止部１１，１１を縦框材２の中空部２ａに至らしめるとともに、接合部材６の基板７を縦框材２の側面に当接する。
この場合、係止部１１を孔１３に挿入した際に、傾斜面１１ｂが孔１３の入口縁部によって押されて、係止爪１１ａ…が内側に弾性的に撓み、この状態で、係止部１１を孔１３に挿入していき、係止部１１が中空部２ａに至った際に、係止爪１１ａ…が、その弾性復帰力によって外側に撓み、孔１３の縁部に係止する。
また、接合部材６の凸条１０を縦框材２の凹溝１２にはめ込む際に、凹溝１２の側面の突起が、凸条１０の側面の突起間に係合することによって凹溝１２と凸条１０の嵌合が強固なものとなる。なお、凸条１０を凹溝１２にはめ込む際に、凸条１０の外面または凹溝１２の内壁面に接着剤を塗布しておき、この接着剤によって凸条１０を凹溝１２の内壁面に接着固定しもよい。
【００３８】
なお、本例では、横框材３に接合部材６を取付けてから、この接合部材６を縦框材２に取付けることによって、これら框材２，３どうしを接合したが、これとは逆に、縦框材２に接合部材６を取付けてから、この接合部材６を横框材２に取付けることによって、框材２，３どうしを接合してもよく、さらには、接合部材６を同時に横框材３と縦框材２とに取付けることによって、框材２，３どうしを接合してもよい。
【００３９】
このようにして、縦框材２と横框材３とを接合部材６を介して直角に接合することによって、接合部材６の基板７が横框材３の端面と縦框材２の端部側面とに挟まれた状態でこれらに当接しているで、これら框材２，３はその端面に中空部２ａ，３ａが開口していても、基板７を介して安定的に互いに直角に当接される。そして、接合部材６の嵌合部８，９が横框材３の中空部３ａ，３ａに挿入されて嵌合しており、係止部１１が横框材２の側面に形成された凹溝１２の底の孔１３を通して縦框材２の中空部２ａに挿入されたうえで、この孔１３の縁部に係止しているので、中空の縦框材２と横框材３とを容易かつ確実に接合できる。
また、縦框材２の凹溝１２に、接合部材６の凸条１０が嵌合しているので、接合部材６を縦框材２の側面に位置決めして強固に取付けることができ、よって、接合部材６によってより強固に框材２，３どうしを接合できる。
【００４０】
さらに、基板７の一方の面に形成された二つの嵌合部８，９が、横框材３の二つの中空部３ａ，３ａに挿入されて嵌合しているので、縦框材２と横框材３とをより強固に接合できる。
加えて、接合部材６の係止部１１を縦框材２の側面（凹溝１２の底面）に形成された孔１３に挿入して中空部１２ａに至らしめるだけて、該係止部１１の係止爪１１ａ…が弾性復帰して孔１３の縁部に係止するので、係止部１１を孔１３に容易に係止でき、したがって、接合部材６を縦框材２の側面に容易に取付けることができる。
【００４１】
上記のような縦框材２と横框材３との接合は、図１に示すような、ドア１の四つの角部で同様にして行われ、これによって２本の縦框材２，２と２本の横框材３，３とによって枠体４が形成される。
そして、この枠体４内に合板やガラス板で形成された面材５が以下のようにしてはめ込まれる。
【００４２】
すなわち、前記縦框材２の側面に形成されている凹溝１２には、図２および図３に示すように、額縁材１６が挿入されている。この額縁材１６はセルロース系微粉粒と樹脂とを混合して押出成形した上下に長尺なものであり、額縁本体１６ａと、この額縁本体１６ａの裏面に形成された挿入部１６ｂ，１６ｂとから構成されている。
額縁本体１６ａは左右一対の爪部１６ｃ，１６ｃを備えており、この爪部１６ｃ，１６ｃによって面材５の縦方向に沿う縁部が挟持されて保持されている。挿入部１６ｂ，１６ｂは平行離間して設けられており、挿入部１６ｂ，１６ｂの外面間の距離は、前記凹溝１２の溝幅とほぼ等しくなっている。したがって、この挿入部１６ｂ，１６ｂを凹溝１２に挿入して嵌合することによって、額縁材１６が溝１２に固定されている。
【００４３】
また、前記横框材３の内側の側面には、凹溝１７が形成されており、この凹溝１７に額縁材１８が挿入されている。この額縁材１８はセルロース系微粉粒と樹脂とを混合して押出成形した上下に長尺なものであり、額縁本体１８ａと、この額縁本体１８ａの裏面に形成された挿入部１８ｂ，１８ｂとから構成されている。
額縁本体１８ａは左右一対の爪部１８ｃ，１８ｃを備えており、この爪部１８ｃ，１８ｃによって面材５の横方向に沿う縁部が挟持されて保持されている。挿入部１８ｂ，１８ｂは平行離間して設けられており、挿入部１８ｂ，１８ｂの外面間の距離は、前記凹溝１７の溝幅とほぼ等しくなっている。したがって、この挿入部１８ｂ，１８ｂを凹溝１７に挿入して嵌合することによって、額縁材１８が溝１７に固定されている。
【００４４】
なお、本実施の形態では、図１に示すように、枠体４内に縦横に帯材が組み付けられているので、帯材の側面にも、框材２，３と同様に凹溝を形成するとともに、この凹溝に額縁材を挿入し、この額縁材によって面材５の他の縁部を保持する。
【００４５】
このように、面材５は額縁材１６，１８に保持されているので、面材５を額縁材１６，１８を介して枠体４内に確実に保持でき、また框材２，３と面材５との接合部を額縁材１６，１８によって秀麗に仕上げることができる。
【００４６】
なお、本実施の形態では、縦横の框材２，３にそれぞれ形成された凹溝１２，１７に額縁材１６，１８を挿入し、この額縁材１２，１７によって面材５の縁部を保持したが、額縁材１６，１８を使用せずに、凹溝１２，１７に直接面材５の縁部を挿入して嵌合し、これによって面材５を枠体４内に保持してもよい。
また、本実施の形態では、ドア１の縦横の框材２，３内には、それぞれ中空部２ａ，３ａがあるので、この中空部２ａ，３ａにウレタン等の断熱材を充填してもよい。
【００４７】
