Description

【０００１】
【発明の属する技術分野】
本発明は収納庫扉開閉構造に関する。
【０００２】
【従来の技術】
壁面等に設けられる前方に開口部を有する収納庫において、従来では、扉本体が収納庫本体に対して一側縁部を揺動中心として揺動し開閉するものが知られている（例えば、特許文献１参照。）。従って、扉本体が二枚有る収納庫では、扉本体が観音開きするよう構成されている。また、他に知られている構成としては、二枚の扉本体が収納庫本体の開口部側の内部にて、扉本体がレール溝に沿ってスライドし開閉するものがある。
【０００３】
【特許文献１】
特開平９−５１８２１号公報
【０００４】
【発明が解決しようとする課題】
従来のように、扉本体が揺動して開閉される構成では、扉本体が開かれた状態で、扉本体に頭等をぶつけたりしてけがをするおそれがある。あるいは、収納庫を天井近くに設けた場合、扉本体を開けると照明器具等と干渉し、設備配置に自由が効かないという欠点がある。つまり、従来の揺動式の扉開閉構造では、収納庫手前側に広い空間が必要であった。
また、二枚の扉本体をスライドして開閉する構造では、収納庫本体の奥行きがレール溝によって縮小され、また、一方の扉本体を全開しても収納庫の有効開口幅が全幅の半分より小さくなり、また、二枚の扉本体を同時に開状態とできず、全面を開口させることができないという欠点がある。
また、従来の揺動動作により開閉を行う扉開閉構造は、収納庫の大きさに応じた専用の蝶番等により構成されており、扉本体の裏面の上下所定位置に夫々配設されている。従って、蝶番を違う位置に取着変更させたり、左右反対勝手にして用いることができなかった。さらに、扉本体を高さの異なるものに取り替えたくても対応できず、収納庫本体側ごと取り替える必要があるという欠点がある。
また、従来において、扉本体の上下位置に夫々ガイド具（蝶番等）なるものを配設し、これらを鉛直方向の連結杆にて同調動作させるよう構成するものもあるが、連結杆が長くなるとその応答性は劣り、また、構成が複雑で見た目が悪いという欠点がある。
【０００５】
そこで本発明は、開状態の扉本体が収納庫の手前で邪魔にならず、また、収納庫の開口部を完全に開口できて収納物の出し入れが容易で、かつ、操作性がよい収納庫扉開閉構造を提供することを目的とする。
【０００６】
【課題を解決するための手段】
上述の目的を達成するために、本発明に係る収納庫扉開閉構造は、前方に開口部を有する収納庫本体の該開口部において扉本体を開閉させる揺動リニア支持具を備え、該揺動リニア支持具は、該扉本体を一旦手前へ引き出してから側方へスライドして開けるよう構成され、一枚の該扉本体に対して該揺動リニア支持具が一台具備されるものである。
また、上記揺動リニア支持具は、上記扉本体を上記収納庫本体に対して揺動して手前に引き出す平行リンク機構部と、手前に引き出された状態の該扉本体を該収納庫本体に対して側方へスライドさせるリニアガイド機構部と、を備え、さらに、該揺動リニア支持具は上下対称形状に構成されている。
また、上記平行リンク機構部は、第一・第二・第三リンクアームを備え、これらの基端部が上記収納庫本体側において平面視三角形に配置される３つの鉛直軸心廻りに夫々枢着され、かつ、先端部が上記扉本体側において平面視三角形に配置される３つの鉛直軸心廻りに夫々枢着され、上記扉本体を上記収納庫本体に対して揺動して手前に引き出すようにしたものである。
また、上記リニアガイド機構部は、上記扉本体の裏面に取着される上下一対の水平状の丸棒レール部材と、上記平行リンク機構部の上記扉本体側と連結されて該丸棒レール部材を外嵌保持する上下一対の円筒状リニア軸受部材と、を備え、該丸棒レール部材が該リニア軸受部材によりガイドされて該扉本体がスライド自在となるようにしたものである。
また、上記揺動リニア支持具は、上記扉本体の裏面に取着される鉛直方向のガイド軸部材を備え、さらに、上記平行リンク機構部側に、該扉本体が揺動する際に該ガイド軸部材を挿入状として誘導しかつ上記平行リンク機構部により該扉本体が手前引き出し状態となった際に該ガイド軸部材を離脱可能とさせる円弧状ガイド溝を形成した揺動ガイド部材を備えたものである。
【０００７】
【発明の実施の形態】
以下、図示の実施の形態に基づき、本発明を詳説する。
【０００８】
図１は本発明に係る収納庫扉開閉構造を有する収納庫の実施の一形態を示す平面図であり、図２はその収納庫の正面図、図３と図４はその収納庫の側面断面図である。なお、図１は上面板が外された状態の平面図である。
図１〜図４の収納庫は、収納部（収納庫本体１）が２箇並設されたものであり、それに対応して扉本体２も二枚有している。なお、収納庫の形態はこれに限らず、１個の収納庫本体１に一枚の扉本体２により構成されたものでもよい。
【０００９】
そして、本発明に係る収納庫扉開閉構造は、前方に開口部１０を有する収納庫本体１の開口部１０において扉本体２を開閉させる揺動リニア支持具Ｇを備えており、揺動リニア支持具Ｇは収納庫本体１の側壁１４（右側壁）に接続され、扉本体２を一旦手前へ引き出してから左右方向の一方側の側方へスライドさせて開けることができるよう構成されている。また、一枚の扉本体２に対して一台の揺動リニア支持具Ｇのみとし、揺動リニア支持具Ｇは上下対称形状に構成されている。従って図示の実施例では、扉本体２を正面視右側方へスライド移動させるよう構成しているが、揺動リニア支持具Ｇを上下逆にして反対面側の側壁１５（左側壁）に左右反対勝手に取着させることで、扉本体２を左側方へスライド移動させることができる。また、揺動リニア支持具Ｇは既にある収納庫に対し後付けも可能である。
【００１０】
図５は扉本体２が全閉状態にある収納庫扉開閉構造で扉本体２を省略した正面図であり、図６は扉本体２が全開状態にある背面斜視図であり、収納庫本体１を省略している。図７、図８、図９と図１０は収納庫扉開閉構造を説明する平面図であるが、これらは順に、扉本体２が全閉状態、手前引き出し状態、スライド移動前の状態、全開状態を示す。これらの図により揺動リニア支持具Ｇを具体的に説明すると、支持具Ｇは、扉本体２を収納庫本体１に対して揺動して手前に引き出させる平行リンク機構部３と、手前に引き出された状態の扉本体２を収納庫本体１に対して側方へスライドさせるリニアガイド機構部４と、を備えている。
【００１１】
平行リンク機構部３は、第一リンクアーム５、第二リンクアーム６、第三リンクアーム７を備えており、これらの基端部が収納庫本体１側において平面視三角形に配置される３つの鉛直軸心廻りに夫々枢着され、かつ、先端部が扉本体２側において平面視三角形に配置される（上記鉛直軸心とは別の）３つの鉛直軸心廻りに夫々枢着され、扉本体２を収納庫本体１に対して平行状態を保ったまま揺動して手前に引き出すようにしている。
【００１２】
つまり平行リンク機構部３は、収納庫本体１の側壁１４（又は１５）にビス等にて図示省略の座金部材を介して高さ・向き調整可能に固定されるベース部材１６と、扉本体２側と（リニアガイド機構部４を介在させて）接続されるガイド部材１８と、ベース部材１６の取付部１７に第一鉛直軸心２１廻りに揺動自在に基端部が枢着されかつガイド部材１８に第二鉛直軸心２２廻りに揺動自在に先端部が枢着された第一リンクアーム５と、取付部１７に第三鉛直軸心２３廻りに揺動自在に基端部が枢着されかつガイド部材１８に第四鉛直軸心２４廻りに揺動自在に先端部が枢着された第二リンクアーム６と、取付部１７に第五鉛直軸心２５廻りに揺動自在に基端部が枢着されかつガイド部材１８に第六鉛直軸心２６廻りに揺動自在に先端部が枢着された第三リンクアーム６と、を備える。
【００１３】
つまり、揺動リニア支持具Ｇの基端部側であるベース部材１６の取付部１７に、第一鉛直軸心２１と第三鉛直軸心２３と第五鉛直軸心２５とが配設され、これらが三角形（略正三角形）に配置される。また、揺動リニア支持具Ｇの先端部側であるガイド部材１８に、第二鉛直軸心２２と第四鉛直軸心２４と第六鉛直軸心２６とが配設され、これらが三角形（略正三角形）に配置される。そして、取付部１７側の三角形状とガイド部材１８側の三角形状は同一形状であり、第一・第二・第三リンクアーム５，６，７とが相互に平行状態で揺動する複合平行リンクを構成する。
【００１４】
また、平面視において、第一鉛直軸心２１と第五鉛直軸心２５、及び、第二鉛直軸心２２と第六鉛直軸心２６、が夫々取付部１７、及び、ガイド部材１８において、第三鉛直軸心２３、及び、第四鉛直軸心２４より手前側に配置され三角形配置となる。さらに、第一鉛直軸心２１と第二鉛直軸心２２とを結ぶ直線と、第五鉛直軸心２５と第六鉛直軸心２６とを結ぶ直線とは、扉本体２の揺動引き出し角度の範囲内において（使用範囲内において）、平面視同一直線上とならないようにしている。
【００１５】
第一リンクアーム５は、図５と図６に示すように一枚の鉛直盤状の揺動部材であり、第一リンクアーム５のうち基端部側（収納庫本体１側）の上部・下部において夫々ベース部材１６の取付部１７，１７に枢着され、先端部側（扉本体２側）の上部・下部において夫々ガイド部材１８に枢着される。
また、第二リンクアーム６は、盤状の第一リンクアーム５の上方及び下方位置に夫々配設されて一対で一組とされた円弧状補助揺動アーム板であり、夫々の基端部側が取付部１７，１７に枢着され、先端部側がガイド部材１８に枢着されている。なお、第二リンクアーム６は、図９に示すように扉本体２の揺動引き出し角度が９０°を越えて扉本体２を手前引き出し状態とした際に、収納庫本体１の側壁１４と干渉するのを防止するために湾曲状とされている。
【００１６】
さらに、第三リンクアーム７は、盤状の第一リンクアーム５の上縁と下縁との間に配設され上下一対で一組とされた直線状リンクアーム板であり、夫々の基端部側が取付部１７，１７に枢着され、先端部側がガイド部材１８に枢着されている。
この平行リンク機構部３は、３つのリンクアームを備え、１つを（第二リンクアーム６を）他の２つの上下位置に高さを違えて配設し、コンパクトな構造とし、揺動に際し干渉しないようにしている。
【００１７】
この構成によれば、図７〜図９に示すように、扉本体２の揺動引き出し角度の範囲内において、平面視３つのリンクアームの全てが直線状に並ぶことがないため、常に平行リンク機構部３は鉛直軸心間隔Ｐが広い平行四辺形を保つことができる。このため支持具Ｇの剛性は高く、片持ち状となる扉本体２の荷重を安定して保持しスムーズに開閉動作させることができる。このように常に剛性を有することができる構成であるため、扉本体２の揺動引き出し角度が９０°を越えることが可能となる。従って、扉本体２を収納庫本体１の開口部１０から大きく側方外方へ位置させることができ、開口部１０を広く開放させることができる。
【００１８】
また図９に示すように、上記３種のリンクアームのうちの１つ（本発明では第三リンクアーム７）の基端部側の所定位置に切欠によるストッパ部３０を形成し、ストッパ部３０が側壁１４に固定されるベース部材１６に当接することで扉本体２の手前引き出し位置を決定できる。なおこの揺動引き出し角度は各リンクアームの揺動角度と一致し、扉本体２が全閉状態で０°となる。そして、揺動角度は９０°を越えて任意に設定可能であるが、全閉の０°から全開の１３５ °程度としている。
【００１９】
次に、リニアガイド機構部４について説明すると、図５と図６に示すように、リニアガイド機構部４は、扉本体２の裏面２ａに取着される上下一対の水平状の中空又は中実の丸棒レール部材８，８と、平行リンク機構部３の扉本体２側（先端部側）と連結されて丸棒レール部材８を外嵌保持する上下一対の円筒状リニア軸受部材（リニアベアリング）９と、を備えている。そして、丸棒レール部材８がリニア軸受部材９によりガイドされて扉本体２が、図９と図１０に示すように平行リンク機構部３の先端部側において、スライド自在となる。
【００２０】
直線状の丸棒レール部材８，８は、夫々両端部側において、扉本体２の裏面２ａにビス等にて連結させた固定用治具１９，１９により固定されており、治具１９，１９がスライド移動のストローク始点・終点用のストッパともなる。
円筒状リニア軸受部材９は、丸棒レール部材８の長手方向に対して滑らかに転動自在の転がり軸受を複数個内周面に有する円筒状の軸受部材であり、丸棒レール部材８の外周面円周方向に複数箇所接触可能である。そして、この円筒状リニア軸受部材９が、平行リンク機構部３の先端部側のガイド部材１８に接続されている。つまり、扉本体２は、基端部が収納庫本体１に接続された平行リンク機構部３の先端部に、リニアガイド機構部４を介在させ、接続されている。
【００２１】
さらに、揺動リニア支持具Ｇは、図５と図６及び図１１と図１２と図１３の平面説明図に示すように、扉本体２の裏面２ａに取着される鉛直方向のガイド軸部材１１を備えている。このガイド軸部材１１は、正面視右側（全閉状態にある扉本体２に近接する側）の固定用治具１９の一部に形成されている。さらに、揺動リニア支持具Ｇは、第一リンクアーム５の所定位置に配設した揺動ガイド部材１３を備えている。揺動ガイド部材１３には、扉本体２が揺動する際にガイド軸部材１１を挿入状として誘導し、かつ、平行リンク機構部３により扉本体２が手前引き出し状態となった際に始めてガイド軸部材１１を離脱可能とさせる円弧状ガイド溝１２を形成している。つまり、ガイド軸部材１１と揺動ガイド部材１３とによりリニアガイド機構部４に対するスライドストッパとしての機能を有する。そして、このガイド溝１２の一端部には、開口出入口部２９が形成されており、ガイド軸部材１１はこの開口出入口部２９を通過する。
【００２２】
扉本体２側のガイド軸部材１１は、支持具Ｇの略中央高さ位置に同一鉛直線上に二本配設され、相互が向かい合う方向へ延伸し相互の先端部が所定間隔を有している。平行リンク機構部３側の揺動ガイド部材１３は、一対のガイド軸部材１１，１１が挿入状となるよう上下面両側に円弧状ガイド溝１２，１２が形成されており、ガイド溝１２は第二鉛直軸心２２を中心として円弧状に形成され、扉本体２の揺動動作に従ってガイド軸部材１１，１１が、ガイド溝１２，１２内を第二鉛直軸心２２を中心として移動する。つまり、扉本体２が揺動引き出し動作を行う間はガイド軸部材１１がガイド溝１２内に挿入状となるため、扉本体２はスライド移動することができない。
【００２３】
また、平行リンク機構部３は、扉本体２が全閉状態に近づくと閉方向へ、乃至、手前引き出し状態に近づくと手前引き出し方向へ、扉本体２を弾発的に付勢する引張バネ部材２７が、ベース部材１６の取付部１７とガイド部材１８との間に、付設されている。このバネ部材２７は、図７に示すように扉本体２が全閉状態に近づくとバネ部材２７の中心線が上記リンクアーム５，６，７の軸線よりも扉本体閉方向側（収納庫本体１の奥壁側）に配置され取付部１７とガイド部材１８との間を引張って閉方向に揺動させ、扉本体２が手前に引き出され、ある点（デッドポイント）を越えると、図９に示すようにバネ部材２７の中心線が上記リンクアーム５，６，７の軸線のうちの一つよりも扉本体開方向側に配置され、取付部１７とガイド部材１８との間を引張って開方向へ揺動させるよう構成している。
【００２４】
次に、扉本体２を全閉状態から全開状態に移行する際の揺動リニア支持具Ｇの作用（動作）について説明する。符号２８は扉本体２の表面２ｂに取着された取手である。
図７に示す状態では、扉本体２はバネ部材２７の弾発力により全閉状態に保持され勝手に開くことがなく、ぐらつかない。この状態では扉本体２は後方位置にある。そして、取手２８を持ってバネ部材２７の弾発力に抗して扉本体２を手前に引き出していくと、扉本体２は矢印ａの方向に揺動し、図８の扉揺動途中状態を経て、図９の手前引き出し状態となる。この状態で扉本体２は前方位置となり、平行リンク機構部３の先端部側は扉本体２の正面視右側方部に位置する。また、バネ部材２７が扉本体２を開方向へ付勢するため、勝手に扉本体２が閉方向へ閉じることがない。また、平行リンク機構部３の第三リンクアーム７の一部に設けたストッパ部３０が、固定状態のベース部材１６に当接することにより、扉本体２が必要以上に揺動しないように抑制されている。
【００２５】
さらに、この揺動動作の際に、扉本体２側のガイド軸部材１１が、図１１から図１２に示すように、扉本体２の揺動に伴って平行リンク機構部３側の揺動ガイド部材１３の円弧状ガイド溝１２に沿って移動するため、扉本体２はリニアガイド機構部４によりスライド移動することはなく、手前引き出し状態となる。
つまり、扉本体２を収納庫本体１の鉛直開口面に対して正面視、全閉状態の後方左側方と、手前引き出し状態の前方右側方へ、平行状態を保ったまま揺動可能とすることができる。
【００２６】
その後、扉本体２をさらに右側方（矢印ｂの方向）へスライドさせていくと、図１０に示すように、扉本体２の正面視左側方部に平行リンク機構部３の先端部側が位置し、扉本体２が全開状態となる。
また、扉本体２が手前引き出し状態では、扉本体２側のガイド軸部材１１が、図１２に示すように、揺動ガイド部材１３のガイド溝１２の開口出入口部２９に位置し、図１２から図１３に示すように、扉本体２がスライド動作を開始すると、ガイド軸部材１１はその開口出入口部２９を通過して揺動ガイド部材１３から脱して、扉本体２は側方へ直線移動できる。
なお、扉本体２を開状態から閉状態へ移行させる動作は、上記と逆の工程を経て行えばよい。
【００２７】
【発明の効果】
本発明は上述の構成により次のような効果を奏する。
【００２８】
（請求項１によれば）扉本体２を開閉させるために必要な空間が小さくて済み、開状態で扉本体２が大きく突出しないため邪魔にならず、また、照明機器等と干渉するおそれもない。つまり、図１に示すように突出寸法Ｄが小さく済み、扉本体２の開閉にスペースを取らず、収納庫をどのような場所にも設置可能となる。また、扉本体２を収納庫本体１から手前へ一旦引き出してスライドさせるため、収納庫本体１の開口部１０を大きく開状態とすることができ、収納物の出し入れが容易となり収納部を有効利用できる。
揺動リニア支持具Ｇを一台のみとしているため、扉本体２の形状・大きさに左右されることなく設置が可能である。また、一台の揺動リニア支持具Ｇのみの調整により、上下左右に扉本体２の取付位置を簡単に調整できる。
【００２９】
（請求項２によれば）揺動リニア支持具Ｇが上下対称形状に形成されているため、左右反対勝手に取付けが可能となり（扉左右開きが同一機構で対応でき）、左開閉用と右開閉用とに区別する必要がなく、取付けに手間取ることがない。
（請求項３によれば）扉本体２を揺動させ３つのリンクアームの内の２つが平面視重なり状となっても、残りの１つのリンクアームにより揺動リニア支持具Ｇの剛性を保持することができるため、扉本体２を全角度において安定して保持できる。従って、扉本体２の揺動角度を９０°を越えてさらに大きくすることが可能となり、開口部１０の開口度を大きくすることができる。
【００３０】
（請求項４によれば）揺動リニア支持具Ｇが一台であり、扉本体２の重心がリニアガイド機構部４上に無くても、がたつかずスムーズに操作できる。さらに、扉本体２が、上下一対の丸棒レール部材８のどちらか一方に片当たりとなることが防止でき、組み立ての際に精度が出やすく組み付けが容易となる。また、丸棒レール部材８の長さを変えることによりスライドさせる扉本体２の移動距離を変えることが容易にできる。
（請求項５によれば）扉本体２の揺動動作を安定させることができる。一旦扉本体２を所定の手前引き出し状態まで揺動させないと側方へスライドできないよう構成でき、誤操作を防止し、操作性の優れたものとすることができる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a storage door opening / closing structure.
[0002]
[Prior art]
2. Description of the Related Art In a storage provided with an opening in the front provided on a wall surface or the like, conventionally, there is known a storage in which a door main body swings around one side edge with respect to the storage main body to open and close (for example, See Patent Document 1.). Therefore, in a storage having two door bodies, the door body is configured to be double-opened. Further, as another known configuration, there is a configuration in which two door bodies slide along a rail groove and open and close inside the opening side of the storage body.
[0003]
[Patent Document 1]
Japanese Patent Application Laid-Open No. 9-51821
[Problems to be solved by the invention]
In a configuration in which the door main body is opened and closed by swinging as in the related art, there is a possibility that the head or the like may be hit against the door main body or the like in a state where the door main body is opened to cause an injury. Alternatively, when the storage is provided near the ceiling, there is a disadvantage that opening the door body interferes with the lighting equipment and the like, so that the arrangement of the equipment is not effective. That is, in the conventional swing type door opening / closing structure, a large space is required on the front side of the storage.
Moreover, in the structure in which the two door bodies are slid and opened and closed, the depth of the storage body is reduced by the rail groove, and even if one of the door bodies is fully opened, the effective opening width of the storage is more than half of the full width. Further, there is a disadvantage that the doors cannot be opened at the same time because the two door bodies cannot be opened at the same time.
Further, the conventional door opening / closing structure that opens / closes by swinging operation is configured by a dedicated hinge or the like corresponding to the size of the storage, and is disposed at predetermined upper and lower positions on the back surface of the door body. Therefore, the hinge could not be changed to a different position, or the hinge could not be used. Further, there is a drawback that even if it is desired to replace the door main body with one having a different height, it is not possible to cope with it, and it is necessary to replace the entire storage main body.
Conventionally, guides (hinges and the like) are provided at upper and lower positions of the door body, respectively, and these are configured to be tuned by a vertical connecting rod. However, if the connecting rod becomes longer, Its responsiveness is inferior, and it has the disadvantage that its configuration is complicated and its appearance is poor.
[0005]
Therefore, the present invention provides a storage container in which the opened door body does not obstruct the storage container in front of the storage container, and the opening of the storage container can be completely opened so that storage items can be easily taken in and out, and the operability is good. It is an object to provide a door opening and closing structure.
[0006]
[Means for Solving the Problems]
In order to achieve the above object, a storage door opening / closing structure according to the present invention includes a swing linear support for opening and closing the door body at the opening of the storage body having an opening in the front, and The linear support is configured such that the door body is once pulled out to the front and then slid sideways to be opened, and one swing linear support is provided for one door body. .
In addition, the swinging linear support tool swings the door body with respect to the storage body and pulls the door body toward the front, and the door body that is pulled out toward the storage body is connected to the storage body. A linear guide mechanism that slides sideways with respect to the pivotable linear support mechanism, and the swinging linear support is configured to be vertically symmetrical.
The parallel link mechanism includes first, second, and third link arms, and their base ends are respectively pivoted around three vertical axes arranged in a triangular shape in a plan view on the storage body side. The door body is pivotally mounted around three vertical axes arranged in a triangular shape in plan view on the door body side, and the door body is swung with respect to the storage main body and pulled out toward the user. It is like that.
The linear guide mechanism section includes a pair of upper and lower horizontal round bar rail members attached to the back surface of the door body, and the round bar rail member connected to the door body side of the parallel link mechanism section. And a pair of upper and lower cylindrical linear bearing members that externally hold the door, and the round bar rail member is guided by the linear bearing member so that the door body is slidable.
Further, the swing linear support includes a vertical guide shaft member attached to the back surface of the door body, and further includes a guide member which swings toward the parallel link mechanism when the door body swings. A swinging guide member formed with an arcuate guide groove for guiding the shaft member as an insertion shape and enabling the guide shaft member to be detached when the door body is brought into the front drawer state by the parallel link mechanism. Things.
[0007]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, the present invention will be described in detail based on the illustrated embodiments.

The parallel link mechanism 3 has three link arms, one of which (the second link arm 6) is disposed at the other two upper and lower positions at different heights, and has a compact structure. Try not to interfere.
[0017]
According to this configuration, as shown in FIGS. 7 to 9, all the three link arms in plan view do not line up linearly within the range of the swing-out angle of the door body 2, so that the parallel link is always provided. The mechanism section 3 can maintain a parallelogram having a wide vertical axis center interval P. For this reason, the rigidity of the support tool G is high, and the load of the cantilevered door body 2 can be stably held and smoothly opened and closed. As described above, since the configuration can always have rigidity, the swing pulling-out angle of the door main body 2 can exceed 90 °. Therefore, the door main body 2 can be positioned largely laterally outward from the opening 10 of the storage main body 1, and the opening 10 can be widely opened.
[0018]
As shown in FIG. 9, a stopper portion 30 is formed at a predetermined position on the base end side of one of the above-mentioned three types of link arms (the third link arm 7 in the present invention). Abuts against the base member 16 fixed to the side wall 14, the front draw-out position of the door body 2 can be determined. This swing-out angle matches the swing angle of each link arm, and is 0 ° when the door body 2 is fully closed. The swing angle can be arbitrarily set beyond 90 °, but is set to about 0 ° for fully closed to about 135 ° for fully open.
[0019]
Next, the linear guide mechanism 4 will be described. As shown in FIGS. 5 and 6, the linear guide mechanism 4 is a pair of upper and lower horizontal hollow or solid members attached to the back surface 2a of the door body 2. And a pair of upper and lower cylindrical linear bearing members (linear bearings) connected to the door body 2 side (tip end side) of the parallel link mechanism unit 3 and externally holding the round bar rail member 8. 9). Then, the round bar rail member 8 is guided by the linear bearing member 9, and the door main body 2 is slidable on the distal end side of the parallel link mechanism 3 as shown in FIGS. 9 and 10.
[0020]
The linear round bar rail members 8, 8 are fixed at both end sides by fixing jigs 19, 19 connected to the back surface 2a of the door body 2 by screws or the like. Also serve as stoppers for the start and end points of the stroke of the slide movement.
The cylindrical linear bearing member 9 is a cylindrical bearing member having a plurality of rolling bearings that can smoothly roll in the longitudinal direction of the round bar rail member 8 on the inner peripheral surface. A plurality of locations can be contacted in the surface circumferential direction. The cylindrical linear bearing member 9 is connected to a guide member 18 on the distal end side of the parallel link mechanism 3. That is, the door main body 2 is connected to the distal end of the parallel link mechanism 3 whose base end is connected to the storage main body 1 with the linear guide mechanism 4 interposed therebetween.
[0021]
Further, as shown in the plan explanatory views of FIGS. 5 and 6 and FIGS. 11, 12 and 13, the swing linear support G is a vertical guide shaft member attached to the back surface 2 a of the door body 2. 11 is provided. The guide shaft member 11 is formed on a part of a fixing jig 19 on the right side in front view (on the side close to the door body 2 in a fully closed state). Further, the swing linear support G includes a swing guide member 13 disposed at a predetermined position of the first link arm 5. The guide shaft member 11 is guided into the swing guide member 13 when the door body 2 swings, and is guided only when the door body 2 is pulled out by the parallel link mechanism 3. An arc-shaped guide groove 12 that allows the shaft member 11 to be detached is formed. That is, the guide shaft member 11 and the swing guide member 13 function as a slide stopper for the linear guide mechanism 4. An opening / entrance 29 is formed at one end of the guide groove 12, and the guide shaft member 11 passes through the opening / entrance 29.
[0022]
The two guide shaft members 11 on the side of the door main body 2 are arranged on the same vertical line at a position substantially at the center of the support tool G, extend in the direction in which they face each other, and have a predetermined interval between their tips. . The swing guide member 13 on the side of the parallel link mechanism 3 has arc-shaped guide grooves 12 on both sides of the upper and lower surfaces so that the pair of guide shaft members 11 is inserted. The guide shaft members 11, 11 are formed in an arc shape about the second vertical axis 22, and move around the second vertical axis 22 in the guide grooves 12, 12 according to the swinging operation of the door body 2. That is, the guide shaft member 11 is inserted into the guide groove 12 while the door body 2 performs the swing-out operation, so that the door body 2 cannot slide.
[0023]
The parallel link mechanism portion 3 is a tension spring member that resiliently urges the door body 2 in the closing direction when the door body 2 approaches the fully closed state, or in the front drawing direction when approaching the near-drawing state. 27 is provided between the mounting portion 17 of the base member 16 and the guide member 18. As shown in FIG. 7, when the door body 2 approaches the fully closed state, the center line of the spring member 27 is closer to the door body closing direction than the axis of the link arms 5, 6, and 7 (the storage body body). When the door body 2 is pulled out to the front side and pulled beyond a certain point (dead point), the space between the mounting portion 17 and the guide member 18 is pulled and swung in the closing direction. As shown in the figure, the center line of the spring member 27 is disposed closer to the door main body opening direction than one of the axes of the link arms 5, 6, and 7, and the space between the mounting portion 17 and the guide member 18 is pulled. It is configured to swing in the opening direction.
[0024]
Next, the action (operation) of the swing linear support G when the door body 2 shifts from the fully closed state to the fully opened state will be described. Reference numeral 28 denotes a handle attached to the front surface 2b of the door body 2.
In the state shown in FIG. 7, the door body 2 is held in the fully closed state by the elastic force of the spring member 27, does not open without permission, and does not move. In this state, the door body 2 is at the rear position. When the user pulls the door body 2 toward the user against the elastic force of the spring member 27 by holding the handle 28, the door body 2 swings in the direction of arrow a, and the door swinging state shown in FIG. , The state shown in FIG. In this state, the door body 2 is at the front position, and the distal end side of the parallel link mechanism 3 is located on the right side of the door body 2 when viewed from the front. Further, since the spring member 27 urges the door main body 2 in the opening direction, the door main body 2 does not arbitrarily close in the closing direction. Further, the stopper 30 provided on a part of the third link arm 7 of the parallel link mechanism 3 abuts on the fixed base member 16 so that the door main body 2 is prevented from swinging more than necessary. ing.
[0025]
Further, at the time of this swinging operation, the guide shaft member 11 on the side of the door body 2 swings along with the swinging movement of the door body 2 as shown in FIGS. Since the door body 2 moves along the arc-shaped guide groove 12 of the member 13, the door main body 2 does not slide by the linear guide mechanism 4, and is brought into the front drawer state.
In other words, the door main body 2 can be swung to the rear opening left side in the fully closed state and the front right side in the front drawing state with respect to the vertical opening surface of the storage main body 1 while maintaining the parallel state. Can be.
[0026]
Thereafter, when the door body 2 is further slid to the right (in the direction of arrow b), the distal end side of the parallel link mechanism 3 is located on the left side of the door body 2 in front view as shown in FIG. Then, the door body 2 is fully opened.
Further, when the door body 2 is pulled out to the front, the guide shaft member 11 on the door body 2 side is located at the opening / entrance portion 29 of the guide groove 12 of the swing guide member 13 as shown in FIG. As shown in FIG. 13, when the door body 2 starts the sliding operation, the guide shaft member 11 passes through the opening / entrance portion 29 and is disengaged from the swing guide member 13, and the door body 2 can linearly move laterally. .
Note that the operation of shifting the door main body 2 from the open state to the closed state may be performed through a process reverse to the above.
[0027]
【The invention's effect】
The present invention has the following effects by the above configuration.
[0028]
(According to claim 1) The space required for opening and closing the door main body 2 is small, and the door main body 2 does not greatly protrude in the open state, so that it does not become a hindrance, and there is a possibility of interference with lighting equipment and the like. Absent. That is, as shown in FIG. 1, the protrusion dimension D is small, and no space is required for opening and closing the door body 2, and the storage can be installed at any place. Further, since the door body 2 is once pulled out from the storage main body 1 and slid, the opening 10 of the storage main body 1 can be largely opened, so that it is easy to take in and out the storage items, and the storage part is effectively used. it can.
Since there is only one swing linear support G, installation is possible without being affected by the shape and size of the door body 2. Further, the mounting position of the door main body 2 can be easily adjusted vertically and horizontally by adjusting only one swing linear support G.
[0029]
(According to claim 2) Since the oscillating linear support G is formed in a vertically symmetrical shape, it can be mounted on the left and right sides independently (the door can be opened and closed by the same mechanism), and the left and right opening and closing can be used. There is no need to distinguish between opening and closing, and there is no need for installation.
(According to claim 3) Even if the door main body 2 is swung and two of the three link arms overlap in plan view, the rigidity of the swing linear support G is maintained by the remaining one link arm. Therefore, the door body 2 can be stably held at all angles. Therefore, the swing angle of the door body 2 can be further increased beyond 90 °, and the opening degree of the opening 10 can be increased.
[0030]
(According to claim 4) The number of the swing linear supports G is one, and even if the center of gravity of the door body 2 is not on the linear guide mechanism 4, the operation can be smoothly performed without rattling. Further, the door main body 2 can be prevented from hitting one of the pair of upper and lower round bar rail members 8 at one side, so that accuracy can be easily obtained at the time of assembling, and the assembling becomes easy. Further, by changing the length of the round bar rail member 8, the moving distance of the door body 2 to be slid can be easily changed.
According to the fifth aspect, the swinging operation of the door body 2 can be stabilized. The door main body 2 can be configured so that it cannot slide to the side unless it is once swung to the predetermined front drawer state, thereby preventing erroneous operation and improving operability.
