Description

【０００１】
【発明が属する技術分野】本発明は、大型通信機器筐体などに使用される扉の多点締込みロック装置に関するものである。
【０００２】
【従来の技術】通常の大型通信機器筐体では、ロックハンドル装置のロック板による密閉方式が主流である。
この方式では、扉の左右一側に装着したヒンジによって扉を筐体に回転可能に連結し、扉の左右他側の１箇所に装着したロックハンドル装置の施錠軸にロック板を連動装備し、ヒンジ軸を中心に扉を閉鎖回転させた後、施錠軸を操作ハンドルで回して前記ロック板を筐体側の受金部に迫り合い係合させ、これによって扉と筐体間に装着したパッキングを締め込み圧縮している。
【０００３】
しかしながら、この密閉方式では、扉に反りや捻れが発生した場合、ロック板と受金部の迫り合い係合が不十分となり、これがパッキングの圧縮不足となって密閉性能が低下する懸念がある。
扉の反りや捻れに対抗するために扉にロックハンドル装置を多数箇所に装着することも考えられるが、多数のロックハンドル装置を操作するのは非常に煩わしいばかりか、どれか一つ又は幾つかの操作忘れによって所期の密閉性能が得られないことがある。
【０００４】
また、多数個のロックハンドル装置を設けた場合には、全てのロックハンドル装置による締め込み操作は同時に実行されなければならない。その、理由は、一部のロックハンドル装置のロック棒が先に操作されると、未操作のロックハンドル装置のロック棒が担当する個所にあるパッキングが、既操作箇所の圧縮変形の逃げとして膨らんでしまうため、扉が斜めに浮き出てしまい、未操作のロック棒が筐体側の対応する受金部から係合不可能な程度に離れてしまうからである。
このような多数箇所のロックハンドル装置を同時に締め込み操作するには、一人の作業員では不可能であり、複数の作業員を担当させる必要がある。
【０００５】
【発明が解決しようとする課題】したがって本発明の目的は、操作点が１箇所であるにもかかわらず、パッキングの締付けを扉の三辺の全長にわたってほぼ均等かつ的確に行なえ、安定した密閉性能を確保することができる扉用多点締込みロック装置を提供することである。
本発明の別の目的は、運動方向の変換機構やロック部材の駆動機構が簡略化され、製作加工コストが節減される扉用多点締込みロック装置を提供することである。
【０００６】
【課題を解決するための手段】以下、添付図面中の参照符号を用いて説明すると、本発明の扉用多点締込みロック装置では、扉１の自由端側の垂直辺２と上側水平辺３が交差する隅部にデルタ板形状の上位コネクタ部材４を配置し、上位コネクタ部材４をその下部角部において扉１側に枢着し、扉１の上側水平辺３に沿って水平方向に移動案内させて上位水平サポート部材５を扉１側に取付け、上位コネクタ部材４を二つの上部角部の一方において上位クランクレバー３２を介して上位水平サポート部材５の基端に枢着し、扉１の前記垂直辺２に沿って垂直方向に移動案内させて上位垂直サポート部材６を扉１側に取付け、上位コネクタ部材４を二つの上部角部の他方において別の上位クランクレバー３３を介して上位垂直サポート部材６の上端に枢着する。
【０００７】
扉１の前記垂直辺２と下側水平辺７が交差する隅部にデルタ板形状の下位コネクタ部材８を配置し、下位コネクタ部材８をその上部角部において扉１側に枢着し、扉１の下側水平辺７に沿って水平方向に移動案内させて下位水平サポート部材９を扉１側に取付け、下位コネクタ部材８を二つの下部角部の一方において下位クランクレバー６９を介して下位水平サポート部材９の基端に枢着し、扉１の前記垂直辺２に沿って垂直方向に移動案内させて下位垂直サポート部材１０を扉１側に取付け、下位コネクタ部材８を二つの下部角部の他方において別の下位クランクレバー７０を介して下位垂直サポート部材１０の下端に枢着し、
上位クランクレバー３２，３３と上位水平サポート部材５及び上位垂直サポート部材６との各枢着部、並びに下位クランクレバー６９，７０と下位水平サポート部材９及び下位垂直サポート部材１０との各枢着部に遊びを無くし、
扉１の外部から回転力が入力される駆動主軸１１を扉１側に装備し、駆動主軸１１の内端に駆動レバー部材１２をその中間点において固着し、駆動レバー部材１２の一方端に上位連動アーム部材１３の下端を枢着し、上位連動アーム部材１３の上端に上位垂直サポート部材６の下端を枢着し、駆動レバー部材１２の他方端に下位連動アーム部材１４の上端を枢着し、下位連動アーム部材１４の下端に下位垂直サポート部材１０の上端を枢着する。
【０００８】
扉１の上側水平辺３に沿って複数個の第１ロック部材１５をその中間部において扉１側に枢着し、駆動主軸１１の正逆回転によって上位水平サポート部材５が水平方向に進退するとき、第１ロック部材１５の先端部が筐体１６の上側水平辺部１７に係脱するように、第１ロック部材１５の基端部を上位水平サポート部材５に枢着し、
扉１の前記垂直辺２に沿って複数個の第２ロック部材１８をその中間部において扉１側に枢着し、駆動主軸１１の正逆回転によって上位垂直サポート部材６が垂直方向に進退するとき、第２ロック部材１８の先端部が筐体１６の垂直辺部１９に係脱するように、第２ロック部材１８の基端部を上位垂直サポート部材６に枢着する。
【０００９】
扉１の下側水平辺７に沿って複数個の第３ロック部材２０をその中間部において扉１側に枢着し、駆動主軸１１の正逆回転によって下位水平サポート部材９が水平方向に進退するとき、第３ロック部材２０の先端部が筐体１６の下側水平辺部２１に係脱するように、第３ロック部材２０の基端部を下位水平サポート部材９に枢着し、
扉１の前記垂直辺２に沿って複数個の第４ロック部材２２をその中間部において扉１側に枢着し、駆動主軸１１の正逆回転によって下位垂直サポート部材１０が垂直方向に進退するとき、第４ロック部材２２の先端部が筐体１６の垂直辺部１９に係脱するように、第４ロック部材２２の基端部を下位垂直サポート部材１０に枢着する。
【００１０】
【発明の作用】この扉用多点締付けロック装置では、図１に示したように扉１が筐体１６に締付けロックされているときには、連動レバー部材１２は両端を結ぶ長軸が水平線に対してほぼ４５度に傾斜した位置にあり、上位連動アーム部材１３は、連動レバー部材１２との枢着点１１０が駆動主軸１１に立てた垂直線より右側に来ている最上限位置にあり、上位垂直サポート部材６は最も押し上げられた前進位置にある。上位コネクタ部材４は、上位クランクレバー３２との枢着点３６が別のクランクレバー３３との枢着点３７と同じ水平高さに来ている倒立位置にあり、上位水平サポート部材５はヒンジ２４側に押し動かされた前進位置にある。
他方、下位連動アーム部材１４は、連動レバー部材１２との枢着点１１１が駆動主軸１１に立てた垂直線より左側に来ている最下限位置にあり、下位垂直サポート部材６は最も押し下げられた前進位置にある。下位コネクタ部材８は、下位クランクレバー６９との枢着点７４が別の下位クランクレバー７０との枢着点と同じ水平高さに来ている正立位置にあり、下位水平サポート部材９はヒンジ２４側に押し動かされた前進位置にある。
第２ロック部材１８について図１４に示したように、各ロック部材の先端部は筐体１６の各辺部と密接係合している。
【００１１】
扉１の正面側に装備されたロックハンドル装置２５を操作して駆動主軸１１を解錠方向に回したときには、図１において駆動レバー部材１２が時計回り方向に回動するため、上位連動アーム部材１３は、連動レバー部材１２との枢着点１１０が駆動主軸１１を通る水平線の下側に来るように牽引され、上位垂直サポート部材６と上位クランクレバー３３は最も引き下げられた後退位置に牽引される。この上位垂直プレート部材６の牽引によって、第２ロック部材１８と上位垂直プレート部材６との枢着点４５が下降するため、第２ロック部材１８は扉１側との枢着点３８を中心に図１において反時計回り方向に回動し、図１５に示したように第２ロック部材１８の先端部が筐体１６の垂直辺部１９から離脱する。
また、上位垂直プレート６及び上位クランクレバー３３の下向きの後退移動にともなって、上位コネクタ部材４が扉１側との枢着点３１を中心として図１において時計回り方向に回動するため、上位水平プレート部材５及び上位クランクレバー３２が図１において最も右側に移動した後退位置に牽引される。この上位水平プレート部材５の牽引によって、第１ロック部材１５と上位水平プレート部材５との枢着点６３が右側に移動するため、第１ロック部材１５は扉１側との枢着点５７を中心として図１において反時計回り方向に回動し、第１ロック部材１５の先端部が筐体１６の上側水平辺部１７から離脱する。
【００１２】
他方、前記のように駆動主軸１１を解錠方向に回したときには、下位連動アーム部材１４は、連動レバー部材１２との枢着点１１１が駆動主軸１１を通る水平線の上側に来るように牽引され、下位垂直サポート部材１０と下位クランクレバー７０は最も引き上げられた後退位置に牽引される。この下位垂直プレート部材１０の牽引によって、第４ロック部材２２と下位垂直プレート部材１０との枢着点８２が上昇するため、第４ロック部材２２は扉１側との枢着点７５を中心に図１において時計回り方向に回動し、図１７に示したように第４ロック部材２２の先端部が筐体１６の垂直辺部１９から離脱する。
また、下位垂直プレート１０の上向きの後退移動にともなって、下位コネクタ部材８が扉１側との枢着点６８を中心として図１において反時計回り方向に回動するため、下位水平プレート部材９と下位クランクレバー６９が図１において最も右側に移動した後退位置に牽引される。この下位水平プレート部材９の牽引によって、第３ロック部材２０と下位水平プレート部材９との枢着点１００が右側に移動するため、第３ロック部材２０は扉１側との枢着点９４を中心として図１において時計回り方向に回動し、第３ロック部材２０の先端部が筐体１６の下側水平辺部２１から離脱する。
【００１３】
このようにして扉１は上側水平辺３と下側水平辺７及び自由端側の垂直辺２の三辺における締付けロックを解除されるため、前記ロックハンドル装置２５などを使用することによって、収蔵機器の点検修理等の作業のために扉１がヒンジ２４を中心に開放される。
【００１４】
扉１を閉鎖した後、駆動主軸１１を施錠方向に回すと、図３において駆動レバー部材１２が反時計回り方向に回動するため、上位連動アーム部材１３は、連動レバー部材１２との枢着点１１０が駆動主軸１１を通る水平線の上側に来るように押され、上位垂直サポート部材６と上位クランクレバー３３は最も押し上げられた前進位置に動かされる。
この上位垂直プレート部材６の上向き前進移動によって、第２ロック部材１８と上位垂直プレート部材６との枢着点４５が上昇するため、第２ロック部材１８は扉１側との枢着点３８を中心に図３において時計回り方向に回動し、図１４に示したように第２ロック部材１８の先端部が筐体１６の垂直辺部１９に係合する。また、上位垂直プレート６及びクランクレバー３３の前進移動にともなって、上位コネクタ部材４が扉１側との枢着点３１を中心として図３において反時計回り方向に回動するため、上位水平プレート部材５が図３においてヒンジ２４側に接近した前進位置に押し動かされる。この上位水平プレート部材５の左向き前進移動牽引によって、第１ロック部材１５と上位水平プレート部材５との枢着点６３が左側に移動するため、第１ロック部材１５は扉１側との枢着点５７を中心として図３において時計回り方向に回動し、第１ロック部材１５の先端部が筐体１６の上側水平辺部１７に係合する。
【００１５】
他方、前記のように駆動主軸１１を施錠方向に回したときには、下位連動アーム部材１４は、連動レバー部材１２との枢着点１１１が駆動主軸１１を通る水平線の下側に来るように押され、下位垂直サポート部材１０とクランクレバー７０は最も押し下げられた前進位置に動かされる。この下位垂直プレート部材１０の下向き前進移動によって、第４ロック部材２２と下位垂直プレート部材１０との枢着点８２が下降するため、第４ロック部材２２は扉１側との枢着点７５を中心に図３において反時計回り方向に回動し、図１６に示したように第４ロック部材２２の先端部が筐体１６の垂直辺部１９に係合する。
また、下位垂直プレート１０と下位クランクレバー７０の下向き前進移動にともなって、下位コネクタ部材８が扉１側との枢着点６８を中心として図３において時計回り方向に回動するため、下位水平プレート部材９が図３においてヒンジ２４に接近した前進位置に押し動かされる。この下位水平プレート部材９の左向き前進移動によって、第３ロック部材２０と下位水平プレート部材９との枢着点１００が左側に移動するため、第３ロック部材２０は扉１側との枢着点９４を中心として図１において反時計回り方向に回動し、第３ロック部材２０の先端部が筐体１６の下側水平辺部２１に係合する。
【００１６】
常法にしたがって、第１ロック部材１５、第２ロック部材１８、第３ロック部材２０及び第４ロック部材２２の各先端部には、筐体１６側との迫り合い係合のための折曲げ加工がなされており、迫り合い係合の過程でパッキング２３が適度に圧縮変形され、所要の密閉状態が確保される。
【００１７】
