Description

【０００１】
【発明の属する技術分野】
本発明は、扉枠とその扉枠に開閉自在に蝶着された扉との間に、扉を扉枠に対して締め付ける締め付け装置を備えた扉装置に関する。
【０００２】
【従来の技術】
従来、扉を扉枠に対して締め付ける締め付け装置は、特開２００１−１３２３０４号公報に記載されたクレモンロック装置が知られている。そのクレモンロック装置は、扉に設置したラッチボルトと固定枠体（扉枠）に設置した受金とから成るラッチ機構を介して、扉を閉鎖位置に錠止することができる。そして、扉が閉鎖位置に錠止された状態において、扉に設けたハンドル（ドアノブ）を施錠方向に回転すると、扉を固定枠体（扉枠）に締め付け状態とすることができる。
【０００３】
【発明が解決しようとする課題】
上記のクレモンロック装置では、扉が閉鎖位置に錠止された状態において、扉に設けたハンドルを施錠方向に回転しなければ、扉を扉枠に対して締め付けることができず手間がかかる。そこで、本発明の課題は、扉を扉枠に自動的に締め付けることが容易な扉装置を提供することにある。
【０００４】
【課題を解決するための手段】
上記課題解決のため、本願では、扉枠とその扉枠に開閉自在に蝶着された扉との間に、扉を扉枠に対して締め付ける締め付け装置を備えた扉装置において、扉には締め付け装置の駆動機構を備え、その駆動機構は扉の開閉により操作エネルギーを蓄えるエネルギー蓄積手段を備えるとともに扉を閉鎖した時にエネルギー蓄積手段に蓄えた操作エネルギーを開放する開放トリガーを備え、扉を閉鎖した時に前記駆動機構が開放する前記操作エネルギーにより、前記締め付け装置を自動的に締め付け操作するように構成した。
【０００５】
具体的に駆動機構は、扉の閉鎖動作により揺動する揺動部材を扉に取り付け、その揺動部材に弾性部材の一端を連繋し、その弾性部材の他端を締め付け装置に開放トリガーを介して連繋し、開放トリガーは、弾性部材の他端を固定状態とする所定のロック位置と、扉閉鎖時に前記ロックを解除して弾性部材の他端の固定状態を解除する解除位置との間で移動するように設けてあり、扉開放状態から扉が閉鎖されるまでの間は前記開放トリガーをロック位置として他端を固定状態とした弾性部材に揺動部材を介して操作エネルギを弾性エネルギーとして蓄積し、扉閉鎖時に開放トリガーを解除位置にすることで、弾性部材の他端の固定状態を解除して蓄積された弾性エネルギーで締め付け装置を締め付け動作させるように構成した。
【０００６】
上記の揺動部材は扉枠に設けた固定ピン部材に先端が係合して根元部分が垂直軸線回りに揺動する第１揺動部材と、その揺動部材の揺動で水平軸線回りに揺動するように第１揺動部材と係合している第２揺動部材とから成り、第２揺動部材にばね部材の一端を固定し、ばね部材の他端を押し引き連繋部材に連結し、押し引き連繋部材の先端を開放トリガーを介して締め付け装置に連繋した。
【０００７】
締め付け装置は、扉に設けられる締め付け部材と扉枠に設けられる締め付け係合部材とから成り、押し引き連繋部材の先端を中間部材に係脱構造を介して係脱可能に係合し、その中間部材を前記締め付け部材に連結すると共に開放トリガーと係脱するように設け、押し引き連繋部材と中間部材とが係脱構造を介して係止しかつ中間部材がロック位置にある開放トリガーに係合して保持位置に保持されている状態で、扉が閉鎖されて開放トリガーが解除位置となると、ばね部材の蓄積エネルギーが押し引き連繋部材を介して、保持を解除された中間部材に作用して解除位置にあった締め付け部材を締め付け係合部材に係合させて締め付け動作させるように構成し、さらに、締め付け動作している締め付け部材を解除位置に戻すと共に中間部材を開放トリガーと係止可能な上記保持位置に戻す戻し機構を設け、前記係脱構造を締め付け部材が締め付け動作すると係合が外れるように構成し、前記戻し機構により締め付け部材を解除位置とした後の扉の開き動作により揺動部材を介して押し引き連繋部材がエネルギー開放時と反対に移動して、扉の開放によりロック位置に戻った開放トリガーにより保持位置に保持された中間部材と係合するように構成した。
【０００８】
更に駆動機構は、扉に操作ハンドルを設け、扉を開くためにその操作ハンドルを操作することにより揺動する揺動部材を扉に取り付け、その揺動部材の揺動により弾性部材に操作エネルギーを蓄積するように構成すると共に操作エネルギーを蓄積すると前記揺動部材と係止する開放トリガーを設け、扉閉鎖時に開放トリガーが揺動部材との係止を解除されると、前記弾性部材に蓄積された弾性エネルギーで揺動部材を介して締め付け装置を締め付け動作させるように構成しても良い。そして、締め付け装置は、扉に設けられる締め付け部材と扉枠に設けられるフック部材とから成り、締め付け部材を揺動部材と操作ハンドルとの間に設けた。
【０００９】
具体的に、フック部材の回動軸線と締め付け部材の回動軸線とが直角を成して配置され、その締め付け部材のフック側面には、フック部材と係脱する係合部と、操作ハンドルの操作で締め付け部材が回転した時にフック部材を押し出してフック部材と締め付け部材との係合を解除する解除部分と、フック部材と係合部との係合状態において操作ハンドルの操作で締め付け部材が前記と逆に回転した時に、フック部材を介して扉を扉枠に締め付ける締め付け面とを備えた。
【００１０】
【発明の実施の形態】
実施の形態について図面を参照して説明する。図１は、扉枠２とその扉枠２に開閉自在に蝶着された扉３との間に、扉３を扉枠２に対して締め付ける締め付け装置４を備えた扉装置１であって、締め付け装置４は扉３に備えた駆動機構５により操作されるようになっている。駆動機構５は扉３の開閉により操作エネルギーを蓄えるエネルギー蓄積手段１０を備えるとともに扉３を閉鎖した時にエネルギー蓄積手段１０に蓄えた操作エネルギーを開放する開放トリガー１１を備え、扉３を閉鎖した時に前記駆動機構５が開放する前記操作エネルギーにより、前記締め付け装置４を自動的に締め付け操作するように構成されている。
【００１１】
駆動機構５のエネルギー蓄積手段１０について説明する。エネルギー蓄積手段１０は、扉３の開閉動作により揺動する揺動部材１２に弾性部材１３を連繋したものであり、扉３の上部に設置されている。揺動部材１２は扉枠２（上枠２ａ下面）に設けた固定ピン部材６に先端が係合して根元部分１４ｂが垂直軸線回りに揺動する第１揺動部材１４と、その揺動部材１２の揺動で水平軸線回りに揺動するように第１揺動部材１４と係合している第２揺動部材１５とから成る。扉３の上部にはケース１６が取り付けられ、そのケース１６内には、前記第１，２揺動部材１４，１５が夫々揺動自在に設置されている。先ず第１揺動部材１４について説明する。第１揺動部材１４は板部材１４ａの下面に軸部材１４ｂを固着したものであって、板部材１４ａの先端には切欠き溝１７が設けられている。その切欠き溝１７は先端側が開口している。軸部材１４ｂ（根元部分）の下面には２つの突起部１８，１９が設けられ、一方の突起部１８（第１突起部）は軸部材１４ｂの軸中心に配置され、もう一方１９（第２突起部）は軸部材１４ｂの軸中心から離れた位置であって、前記切欠き溝１７の中心線の延長上に配置されている。ケース１６には、軸部材１４ｂの下面と対峙する支持部を備えたブラケット２０が設置されている。そのブラケット２０の支持部に、扉３上面を貫通した軸部材１４ｂの第１突起部１８が回動自在に嵌め込まれている。
【００１２】
次に第２揺動部材１５について説明する。第２揺動部材１５は、ブラケット２０の下方に、水平軸１５ｅ回りに揺動自在に取り付けられている。第２揺動部材１５の上端には、前記第２突起部１９が係合する溝２１が設けられている。その溝２１は、図４に示すように略く字状に形成されている。そして、溝２１に係合した第１揺動部材１４の第２突起部１９が、第１揺動部材１４の揺動にともなって第１突起部１８を支点に第２揺動部材１５の側面１５ａ側から中心線に向けて揺動すると｛図４（ａ）から（ｂ）｝、第２揺動部材１５の下端がケース１６下面に向けて揺動するようになっている。第２揺動部材１５の下端には、弾性部材として例示する板ばね（ばね部材）１３の一端が固定してあり、前記のように第２揺動部材１５が揺動すると、ばね部材１３の他端が固定位置Ａと解除位置Ｂとの間を揺動する。ばね部材１３の他端には、押し・引き両方向に力を伝達できる押し引き連繋部材７が連結してある。その押し引き連繋部材７の先端側は、ケース１６に設けたプーリ２２を介してケース１６の外側に引き出され、扉３の上部から戸先部を巡って締め付け装置４に達している。そして、押し引き連繋部材７の先端部７ａに取り付けたピン部材８の両端部を、扉３の戸先部分の上下方向中間に設けた締め付け装置４の第１長孔３６（後述）に係合させてある。また、押し引き連繋部材７は、ばね部材１３の他端が固定位置Ａの時には、ピン部材８が第１長孔３６の下端に位置し、ばね部材１３の他端が解除位置Ｂの時には、ピン部材８が第１長孔３６の上端に位置するように長さが設定されている。
【００１３】
前記締め付け装置４について説明する。締め付け装置４は、扉３に設けられる締め付け部材３０と扉枠２（竪枠２ｂ）に設けられる締め付け係合部材３１とから成り、締め付け部材３０を締め付け係合部材３１の内側傾斜面３１ａに係合させると、扉３を扉枠２に対して締め付けたことになる（図５，６の状態）。扉３の戸先部分の上下方向中間にはケース３２が取り付けられ、そのケース３２内には、複数のクランク部材３３ａ〜３３ｄを連結したクランク機構３３が設置されている。そのクランク機構３３は、第１ピン部材３４ａを介して連結した第１，２クランク部材３３ａ，３３ｂの端部と、第２ピン部材３４ｂを介して連結した第３，４クランク部材３３ｃ，３３ｄの端部とを、第３ピン部材３４ｃを介して連結したものである。前記第１ピン部材３４ａの両端部は、両側のケース側板３２ａに設けた第２長孔３５に係合させてあり、第２ピン部材３４ｂの端部はケース側板３２ａに回動自在に取り付けてある。第１，２クランク部材３３ａ，３３ｂの間において、第１ピン部材３４ａには先端にローラ部材３０ａを備えた締め付け部材３０が取り付けられている。また、前記第１長孔３６は、両側のケース側板３２ａに設けられている。これにより、第３ピン部材３４ｃを上下移動させると、第１ピン部材３４ａが第２長孔３５に沿って前後方向に移動され、締め付け部材３０先端のローラ部材３０ａが締め付け係合部材３１に係合する係合位置Ｃ（図６）と、ローラ部材３０ａが扉３端面より内側となる解除位置Ｄとの間で進退移動する。上記係合位置Ｃにおいては、第３ピン部材３４ｃがクランク機構３３のデットポイント（クランク死点）を僅かに越えて上側に位置するようにしてあり（図５の状態）、これにより、係合位置Ｃに押し出された締め付け部材３０はその位置で保持される。
【００１４】
クランク機構３３の上方には、先端にローラ部材１１ａを備えた開放トリガー１１が、ローラ部材１１ａが大きく突出するロック位置Ｅと、竪枠２ｂと係合して押し込まれた解除位置Ｆとの間で移動するように設けられている。開放トリガー１１の後方には付勢部材（バネ）３７が設置されており、扉３の開放時には、バネ３７により開放トリガー１１はロック位置Ｅに付勢されている。そして、扉３の閉鎖時には、竪枠２ｂによって解除位置Ｆに押し込まれる。この開放トリガー１１の中間部には、後述する中間部材３８が通過できる貫通部１１ｂが設けられている。クランク機構３３と開放トリガー１１との間には中間部材３８が配置されている。中間部材３８の下端部に設けた第３長孔３８ａにクランク機構３３の第３ピン部材３４ｃが挿通しており、中間部材３８が上下すると第３ピン部材３４ｃが上下方向へ移動（締め付け部材３０の前後方向への移動）するようになっている。そして、前記開放トリガー１１がロック位置Ｅにある場合（図９の状態）では、中間部材３８の上端は開放トリガー１１の下面と係合して保持位置Ｇに中間部材３８が保持されるようになっており、開放トリガー１１が解除位置Ｆにある場合（図５の状態）では、中間部材３８は貫通部１１ｂを通過して上方に移動可能となっている。
【００１５】
中間部材３８と押し引き連繋部材７の先端部７ａとの間には、係脱構造３９が形成されている。係脱構造３９において、中間部材３８には、断面Ｌ字状の段付き溝部３９ａが形成されると共に板ばね部材３９ｂが備えてある。その段付き溝部３９ａには、第１長孔３６に沿って往復移動する押し引き連繋部材７の先端部７ａの鉤状係止部７ｂが係脱可能に挿入されている。その押し引き連繋部材７の先端部７ａが中間部材３８の下端側に移動した時には、板ばね部材３９ｂに付勢されて段付き溝部３９ａに係止する。この状態では、押し引き連繋部材７の上下方向への移動とともに中間部材３８が上下方向へ移動することになる。第１長孔３６の上端側には、上方に向かって吊元側から戸先側へ傾斜した傾斜面３６ａが形成されている。その傾斜面３６ａに沿って中間部材３８に係止した押し引き連繋部材７が移動すると、先端部７ａの係止部７ｂは板ばね部材３９ｂのばね力に抗して段付き溝部３９ａから離れ、押し引き連繋部材７と中間部材３８の係脱構造３９による係止状態が解除されるようになっている。
【００１６】
締め付け装置４には戻し機構４０が設置されている。戻し機構４０は、ケース底板３２ｂに設置した捩りバネ４１と、第２ピン部材３４ｂに取り付けたレバー部材４２を揺動させる揺動装置４３とから成る。捩りバネ４１は一方の端部がケース後板３２ｃに向けて付勢してあり、その一方の端部を締め付け部材３０に連結してある。第２ピン部材３４ｂに取り付けたレバー部材４２の一方の端部は、第３，４クランク部材３３ｃ、３３ｄの上方に位置するように形成されており、もう一方の端部には、揺動装置４３に連結された連結部材４４が取り付けてある。また、揺動装置４３は、扉３に取り付けた操作ハンドル９を操作することで、連結部材４４を前後方向に移動させるように構成されている。
【００１７】
上記のように構成された駆動機構５と締め付け装置４とを備えた扉装置１の動作について説明する。図８に示すように、扉３が扉枠２から開放されている時には、駆動機構５、締め付け装置４は図９に示すようになっている。この時、駆動機構５のエネルギー蓄積手段１０は、第２突起部１９を第２揺動部材１５の側面１５ａ側に配置することで｛図４（ａ）｝、切欠き溝１７を扉３と扉枠２との間に配置するとともに、ばね部材１３の他端は固定位置Ａにある。開放トリガー１１はバネ３７によりロック位置Ｅに付勢されている。締め付け装置４の締め付け部材３０は、戻し機構４０の捩りバネ４１により解除位置Ｄに付勢されている。その締め付け部材３０が解除位置Ｄにあることで、中間部材３８はロック位置Ｅにある開放トリガー１１に係合して保持位置Ｇに保持されている。そして、中間部材３８の段付き溝部３９ａに挿入された押し引き連繋部材７の先端部７ａは、ばね部材１３の他端が固定位置Ａであることから中間部材３８に係脱構造３９を介して係止されている。
【００１８】
この状態から扉３を閉鎖回転させる。図１０に示すように、扉３の閉鎖回転中に切欠き溝１７が扉枠２の固定ピン部材６に係合する。そして、図１１に示すように、扉３を閉鎖回転し続けると、第１揺動部材１４を介して第２揺動部材１５の下端がケース１６下面に向けて揺動する。この時に、ばね部材１３の他端に連結している押し引き連繋部材７の先端部７ａが保持位置Ｇの中間部材３８に係止していることから、ばね部材１３の他端は固定位置Ａに維持された状態となるが、ばね部材１３の一端は第２揺動部材１５とともにケース１６下面に向けて揺動しようとするので、ばね部材１３が撓んで弾性エネルギーが蓄積される（図１２の状態）。
【００１９】
図１３に示すように、扉３が閉鎖位置に近づくと、扉枠２によって開放トリガー１１が扉３内側に向けて押し込まれる。その後、図１４に示すように、扉３が閉鎖位置に移動すると、開放トリガー１１が解除位置Ｆに移動し、開放トリガー１１と中間部材３８との係合状態が解除される（図１５の状態）。これによって、ばね部材１３の他端の固定状態が解除され、図２に示すように、ばね部材１３の蓄積エネルギー（弾性エネルギー）が解放されて押し引き連繋部材７を介して、保持を解除された中間部材３８に作用して中間部材３８を上方に向けて移動させる。中間部材３８が上方に移動することで、第３ピン部材３４ｃが上方移動して、クランク機構３３を介して解除位置Ｄにあった締め付け部材３０が係合位置Ｃに向けて移動し、締め付け部材３０が締め付け係合部材３１に係合する。すると、扉３を扉枠２に設けたパッキン部材４５を押し付けるように、扉３が扉枠２に対して締め付けられる（図１６の状態）。その後、第３ピン部材３４ｃが、図１７に示すデットポイント（クランク死点）を越えて図５の状態となると締め付け部材３０が係合位置Ｃでロックされる。従って、扉３を閉鎖した時に蓄えられる操作エネルギーにより、締め付け装置４を自動的に締め付け操作するようにしたので、扉３を閉鎖動作させることにより閉鎖位置に移動した扉３を扉枠２に対して締め付けることが可能となる。図５の状態では、押し引き連繋部材７の先端部７ａに取り付けたピン部材８が第１長孔３６の傾斜面３６ａに沿って移動すると、押し引き連繋部材７と中間部材３８との係止状態が解除されている。
【００２０】
次に、上記の扉３を開放する場合について説明する。扉３に取り付けた操作ハンドル９を操作することで、戻し機構４０の揺動装置４３を駆動する。その揺動装置４３によりレバー部材４２を図５で反時計方向に揺動させ、第３，４クランク部材３３ｃ，３３ｄの上縁を押し下げて、第３ピン部材３４ｃをデットポイント（クランク死点）より下方に移動させる。すると、ロック状態を解除された締め付け部材３０は、捩りバネ４１により係合位置Ｃから解除位置Ｄに移動するとともに、中間部材３８を下方に移動させる。この状態において、扉３を開放方向へ回転させる。すると、図１８に示すように、バネ３７により開放トリガー１１がロック位置Ｅに移動し、その開放トリガー１１に中間部材３８は保持される。そして、扉３を開放方向へ回転し続けると、扉枠２の固定ピン部材６に係合している揺動部材１２が扉３を閉鎖する時と逆方向に揺動し、図２で解除位置Ｂにあったばね部材１３の他端が固定位置Ａに移動する。すると、押し引き連繋部材７がエネルギー開放時と反対に移動して、先端部７ａが保持位置Ｇに保持された中間部材３８の段付き溝部３９ａに係合する（図９の状態）。その後、扉３を再び閉鎖動作すれば、上述したようにエネルギー蓄積手段１０に操作エネルギーを蓄えることができる。
【００２１】
次に、別の実施形態について説明する。図１９は、扉枠２とその扉枠２に開閉自在に蝶着された扉３との間に、扉３を扉枠２に対して締め付ける締め付け装置５０を備えた扉装置１であって、上記同様に締め付け装置５０は扉３に備えた駆動機構６０により操作されるようになっている。駆動機構６０について説明する。駆動機構６０は、操作ハンドル９を操作することにより揺動する揺動部材６１により弾性部材６２に操作エネルギーを蓄積するように構成すると共に操作エネルギーを蓄積すると前記揺動部材６１と係止する開放トリガー６３を設け、扉３閉鎖時に開放トリガー６３が揺動部材６１との係止を解除されると、前記弾性部材６２に蓄積された弾性エネルギーで揺動部材６１を介して締め付け装置５０を締め付け動作させるように構成されている。
【００２２】
扉３の戸先部分の上下方向中間に取り付けられたケース６４の上板６４ａと中間板６４ｂとの間には上下方向の支持軸６５が設けられている。その支持軸６５に操作ハンドル９を取り付けるカム体６６が揺動自在に支持されている。その揺動自在のカム体６６を介して操作ハンドル９は、支持軸６５を揺動中心として締付位置Ｈと所定角度揺動した蓄積位置Ｉとに揺動する。カム体６６の先端側には動作カム６７が取り付けてある。カム体６６の下方には揺動部材６１が水平軸線回りに回動自在に取り付けられている。図２０に示すように、揺動部材６１には前方に突出した上下２つの突出部６１ａ，６１ｂが形成されており、支持軸６５を支点に２つの突出部６１ａ，６１ｂが上下方向に揺動するようになっている。揺動部材６１の下側の突出部６１ａ（第１突出部）後方には、弾性部材として例示する圧縮ばね（ばね部材）６２が設置されている。そのばね部材６２により、２つの突出部６１ａ，６１ｂはケース上板６４ａに向けて付勢されている。前記揺動部材６１の下方には軸部材６８が設置されている。その軸部材６８には係脱部材６９が回動自在に取り付けられている。係脱部材６９の下端側には前記揺動部材６１の第１突出部６１ａと係脱可能な係脱部６９ａが形成されており、上端側には開放トリガー６３が取り付けられている。係脱部材６９の前方にはバネ部材７０が設置されている。そのバネ部材７０により、係脱部材６９の上端側が扉枠２に向けて付勢されている。
【００２３】
次に、締め付け装置５０について説明する。締め付け装置５０は、扉３に回動可能に設けられた締め付け部材５１と、扉枠２（竪枠２ｂ）に回動自在に設けられたフック部材５２とから成り、締め付け部材５１がフック部材５２と係合すると、扉３を扉枠２に対して締め付けたことになる（図２０，２１）。扉枠２に垂直軸線回りに回動自在に支持されたフック部材５２の先端５２ａが扉３側に突出し、かつ、扉３の開放方向に捩りバネ５３によって付勢されている。締め付け部材５１は、フック部材５２の回動軸線と直交する軸線（戸先面３ａに対して垂直な軸線）回りに回動するように揺動部材６１とカム体６６との間に取り付けられている。締め付け部材５１の後面には、図２６に示すように、突起部５４が設けられている。操作ハンドル９が締付位置Ｈにある時（図２２の状態）には、動作カム６７が前記突起部５４の一方の端面５４ａに当接し、もう一方の端面５４ｂは、揺動部材６１の第２突出部６１ｂと当接可能となっている。このことから、操作ハンドル９を締付位置Ｈから蓄積位置Ｉに揺動すると、図２６に示すように、動作カム６７を介して締め付け部材５１が回動するとともに、突起部５４により第２突出部６１ｂが下方に押し付けられることで揺動部材６１が揺動するようになっている。
【００２４】
前記締め付け部材５１のフック部材５２と対向する面には、操作ハンドル９の操作で締め付け部材５１が回動した時に、フック部材５２を押し出してフック部材５２と締め付け部材５１との係合を解除する解除部分５５と、締め付け部材５１が前記と逆に回転した時に、フック部材５２を介して扉３を扉枠２に締め付ける締め付け面５６とを備えている。そして、操作ハンドル９が締付位置Ｈから蓄積位置Ｉに揺動する場合には、締め付け部材５１が回転して解除部分５５がフック部材５２を押し出す押し出し角度位置Ｊに揺動するようにしてあり（図２８）、操作ハンドル９が蓄積位置Ｉから締付位置Ｈに揺動する場合には、締め付け部材５１が回転して締め付け面５６がフック部材５２を介して扉３を扉枠２に対して締め付ける締め付け角度位置Ｋ（図２３）に揺動するようにしてある。
【００２５】
上記のように構成された駆動機構６０と締め付け装置５０とを備えた扉装置１の動作について説明する。扉３が扉枠２から開放されている時には、扉枠２のフック部材５２は捩りバネ５３によって先端５２ａが扉３側に突出している。この状態で、扉３に設けた操作ハンドル９を締付位置Ｈから蓄積位置Ｉに揺動する。操作ハンドル９を蓄積位置Ｉにしたことで、締め付け部材５１は押し出し角度位置Ｊに移動する。また、締め付け部材５１の上記回転で、第２突出部６１ｂが突起部５４により押し下げられ、揺動部材６１がケース底板６４ｃに向けて揺動し、下側の第１突出部６１ａは、バネ部材７０により付勢されている係脱部材６９の係合部６９ａに係止される。揺動部材６１が揺動してばね部材６２が圧縮されるので、ばね部材６２には弾性エネルギーが蓄積される。この状態において、図２４に示すように、扉３を閉鎖回転させる。
【００２６】
扉３が閉鎖位置に近づくと、扉３の端面３ａ及び締め付け部材５１によって、フック部材５２が扉枠２の内側に押し込まれる。その後、図２１に示すように、扉３が閉鎖位置に移動すると、開放トリガー６３が扉枠２により扉３内側に押し込まれる。開放トリガー６３がケース後板６４ｄに向けて移動すると、係脱部材６９の係合部６９ａがケース底板６４ｃに向けて移動し、揺動部材６１の第１突出部６１ａと係合部６９ａとの係止状態が解除される（図２９）。その後、ばね部材６２の蓄積エネルギーが揺動部材６１に作用して、揺動部材６１を図２９から図２１の位置に揺動させ、押し出し角度位置Ｊにあった締め付け部材５１を締め付け角度位置Ｋに回転させるとともに、押し込まれていたフック部材５２が捩りバネ５３によって扉３側に突出し、締め付け部材５１がフック部材５２と係合する。すると、扉３を扉枠２に設けたパッキン部材４５を押し込むように、扉３が扉枠２に対して締め付けられる（図２０，２１の状態）。
