Description

【０００１】
【発明の属する技術分野】
本発明は、洗面台、トイレや収納用具等のための家具用扉に関する。
【０００２】
【従来の技術】
家具用扉の中空の上下枠の端部を中空の左右枠の端部にコーナ結合具を用いて連結させ、これら枠に化粧板を組み付けることは知られている。
実開平５−２４８７３号公報や実開平２−１３０９８９号公報は、上下枠と左右枠の両端面を約４５度の角度に切断し、各枠の向かい合う該端面を当接し、Ｌ形のコーナ結合具を用いて中空の各枠を結合し、額縁を構成する。使用されるコーナ結合具は、上下枠の中空部形状に合致する外形部と左右枠の中空部形状に合致する外形部とを直角に交差させる形状となっている。
【０００３】
コーナ結合具を金属板をＬ形に曲げた単純形状としたものが、実開昭６２−４２６８２号公報に開示される。
この公報は、上下左右の各枠に金属板からなるコーナ結合具を挿入する特別に設計した係止溝を設けることを教示する。
【０００４】
これとは別に、特開昭５９−２１０１８０号公報は、左右枠の側面にブロック状の長方形スペーサをビス止めし、このスペーサを上下枠の中空部に挿入し、ビスを上下枠よりスペーサにねじ込み、左右枠に上下枠を固定させることを教示する。

【発明が解決しようとする課題】
上下枠と左右枠との対接面を４５度(角度)の切断面とし、上下枠の中空部形状に相当する部分と左右枠の中空部形状に相当する部分とからなるＬ形のブロック即ちコーナ結合具は、合成樹脂材の成形品又は金属材の鋳造品で作るが、コスト高であり、取付時にコーナ結合具の上下枠への挿入部と左右枠への挿入部の形状が異なるため上下枠の左右枠への組付作業が煩わしい。
【０００７】
金属板をＬ形としたコーナ結合具は、前述した不具合の解消は可能であるが、各枠にコーナ結合具を受ける係止溝の設置が必要となり、枠の設計を複雑にする。加えてコーナ結合具へのビスねじ込み量が少なく、結合強度に問題を残す。
【０００８】
これに対し、ブロック状の長方形スペーサをコーナ結合具として用いる例は、上下枠の端面を左右枠の側面に当接させる形であり、左右枠の長手方向に加わる荷重を左右枠からスペーサにねじ込んだビスの剪断力で受けることになり、強度上に問題を残す。
【０００９】
それ故に、本発明は前述した従来技術の不具合を解消させることを解決すべき課題とする。
【００１０】
【課題を解決するための手段】
本発明は、前述した課題を解決するために、基本的には、断面長方形の中空部を備える上下横枠と、断面長方形の中空部を備える左右縦枠と、端面が４５度に切断された上下横枠と左右縦枠とを対接して結合する直方体状のコーナ結合具とを備え、コーナ結合具の一部は上下横枠の切断部のそれぞれ下方と上方から挿入され、他の部分は左右縦枠の中空部に挿入され、コーナ結合具の、上下横枠と縦枠のなす矩形の面に直交する一方の面には上下方向の全長に沿って第１のビス溝を形成し、コーナ結合具の縦枠に挿入される側面のうち建物側に向く外側面の全長に沿って第２のビス溝を開口形成し、上下横枠のそれぞれ上方と下方から挿通したビスを上記第１のビス溝の延びる方向にねじ込み、横枠の延びる方向に沿って水平に挿通したビスを上記第２のビス溝の延びる方向に直交してねじ込み、上下横枠と左右縦枠を連結したことを特徴とする。
【００１１】
本発明によれば、端面が４５度に切断された上下横枠と左右縦枠とを対接させて枠組みし、コーナ結合具の一部を上下横枠の切断部のそれぞれ下方と上方から挿入し、他の部分は左右縦枠の中空部に挿入する構成であるから、コーナ結合具の組み付け作業が容易であり、また、上下方向に設けられた第１のビス溝に上下横枠よりビスをねじ込み、また建物側に向く外側面の全長に沿って形成された第２のビス溝に左右縦枠よりビスをねじ込んで上下横枠と左右縦枠を連結するので、コーナ結合具へのビスねじ込み量は十分であり、端面が４５度に切断された上下横枠と左右縦枠とを対接させて枠組みする構造であるから、左右縦枠の長手方向に加わる荷重は上下横枠で受けるから、結合強度を確保することができる。
【００１２】
【発明の実施の形態】
図１乃至図３を参照する。家具用扉１は、上下横枠２，３、左右縦枠４，５からなる額縁と、各枠の見付け６にその側縁を収納する好ましくは透明又は乳白色のアクリル板或いはガラス板からなる化粧板７を備える。
上下横枠２，３は同断面形状のものを対称に配し、左右縦枠３，４は同断面形状のものを対称に配する。各枠はアルミニウム合金材の押出形材よりなる。

【００２０】
上下横枠２，３は、図８に示すように、円弧状とすることもできる。この場合にも、図示例のコーナ結合具１２を用いることができる。
コーナ結合具１２の突条１８，１９は、左右縦枠４，５の中空部１０の内面に接し、中空部１０内でのコーナ結合具１２のガタ付きを防止する。
コーナ結合具１２は額縁の四隅に利用でき、しかも、形材を適当な長さに切断するのみであり、その製造は容易である。同一コーナ結合具１２を四隅に利用できるので、部品の補給、管理が簡単となる。
【００２１】
図示例では、上下横枠２，３にコーナ結合具１２をビス止めし、左右縦枠４，５の中空部１０にコーナ結合具１２を挿入したが、予め、左右縦枠４，５にコーナ結合具１２をビス止めし、次いで、上下横枠２，３をコーナ結合具１２にビス止めしてもよい。
コーナ結合具１２の主要部を左右縦枠４，５に挿入する代わりに、上下横枠２，３の主中空部９にコーナ結合具１２の主要部を挿入して、コーナ結合具１２を支持し、これに左右縦枠４，５を保持してもよい。
