【発明の属する技術分野】
本発明は、シャッターカーテンを閉塞状態で施錠、解錠するシャッターの錠装置及びこの錠装置を備えたシャッターに関する。
【０００２】
【従来の技術】
特許文献１，２，３にシャッターの錠装置が開示されている。
特許文献１に開示された錠装置は、シャッターカーテンの最下部に設けた座板に取付けた錠本体、操作部材（連動アーム）と、シャッター枠の下枠に取付けた錠受け（フックアーム）を備え、シャッターカーテンを下降して閉塞状態とすると錠本体の錠（ラッチ）が錠受けに係合して施錠し、操作部材を座板の長手方向に移動すると錠が錠受けから外れて解錠されるものである。
【０００３】
特許文献２に開示された錠装置は、シャッターカーテンの最下部に設けた座板に取付けた錠本体、操作部材（解錠兼用閉操作レバー）と、シャッター枠の側枠に設けた錠受け（ロックピン）を備え、シャッターカーテンを下降して閉塞状態とすると錠本体の錠（ロック片）が錠受けに係合して施錠し、操作部材を上方に回動すると錠が錠受けから外れて解錠されるものである（図８参照）。
【０００４】
特許文献３に開示された錠装置は、シャッターカーテンの最下部に設けた座板（ボトムスラット）に取付けた錠本体、操作部材（第１レバー）と、シャッター枠の下枠に取付けた錠受け（フック受けピン）を備え、シャッターカーテンを下降して閉塞状態とすると錠本体の錠（フックプレート）が錠受けに係止して施錠し、操作部材を上方に回動すると錠が錠受けから外れて解錠されるものである。

【特許文献２】
特開２００２−２２７５７１号公報
【特許文献３】
特開２００２−３６４２７５号公報
【０００６】
【発明が解決しようとする課題】
特許文献１に開示された錠装置は、操作部材を座板の長手方向に移動して解錠するので、操作部材を前述の方向に移動した時に座板を持ち上げてシャッターカーテンを上昇して開放するので、そのシャッターカーテンの解放操作がやりづらい。
【０００７】
特許文献２，３に開示された錠装置は、それぞれ操作部材を上方に回動して解錠するので、その操作部材を上方に回動した後に上に移動することでシャッターカーテンを上昇して開放するので、そのシャッターカーテンの開放操作がやり易い。
【０００８】
しかし、特許文献２に開示された錠装置は、錠本体に施錠揺動片を上下揺動自在に設け、操作部材に設けた係合ピンを施錠揺動片に係合し、操作部材を上方に回動するとピンを介して施錠揺動片が上方に揺動して錠がスプリングで解錠位置に回動する構成で、錠と施錠揺動片が左右方向に並設していると共に、錠受けがシャッター枠の側枠に取付けてある。
このために、錠本体は座板の長手方向端部に取付けることになり、座板の長手方向中間部には取付けできない。
また、施錠揺動片と操作部材が連結され、施錠揺動片は室内外側方向に向かうピンで座板の室内面に沿って上下に揺動し、操作部材は長手方向に向かうピンで室内外側方向に回動するから、操作部材の上方への回動によって施錠揺動片を揺動する際に、その施錠揺動片に無理な力が作用し、破損する恐れがある。
【０００９】
特許文献３に開示された錠装置は、錠本体に上下揺動自在に設けた第２レバーが上方に揺動すると施錠位置の錠がスプリングで解錠位置に回動し、その第２レバーと操作部材が連結された構成で、その第２レバーを操作部材によって上方に揺動するので、前述と同様に操作部材を上方に回動して第２レバーを上方に揺動する際に無理な力が作用し、破損する恐れがある。
【００１０】
また、この錠装置は、左右の操作部材と、左右の第２レバーを備え、その左右の第２レバーは一方が上方に揺動すると他方の第２レバーが上方に揺動するように連結し、錠本体の左右両側方から解錠できるようにしてある。
しかしこの構成であると、一方の操作部材を上方に揺動した時に、一方の第２レバーが上方に揺動し、その一方の第２レバーの揺動で他方の第２レバーが上方に揺動し、それによって他方の操作部材が上方に回動するするので、左右の第２レバーの連結部（錠本体）に無理な力、例えばかじりが生じ破損することがある。
【００１１】
なお、特許文献３に開示された錠装置においては、その図１０に示すように錠本体の上部に操作部材（第２レバー）を座板の長手方向に沿って設け、錠本体の左右両側方から解錠できるようにしているが、このようにすると、錠本体の上に操作部材が位置するから座板の上下寸法が大きくなる。
【００１２】
本発明は、前述の課題に鑑みなされたものであり、その目的は、シャッターカーテンの開放操作がやり易いこと、錠本体を座板の長手方向任意の位置に取付け可能であること、破損する恐れがないこと、錠本体の少なくとも左右一方側から解除できるようにすることが可能で、かつ座板の上下寸法を小さく、錠本体を破損することがないこと、を満足したシャッターの錠装置及びその錠装置を備えたシャッターを提供することである。
【００１３】
【課題を解決するための手段】
第１の発明は、座板７に取付けられる錠本体１０と、下枠６に取付けられる錠受け２０と、前記座板７に上下回動自在に取付けられる操作部材３０を備え、
前記錠本体１０は、錠と保持部材を有し、
その錠は錠受け２０と係合して施錠する施錠姿勢と離脱して解錠する解錠姿勢とに回動し、
前記保持部材は、錠を施錠姿勢で保持する第１位置と、保持を解除する第２位置に移動し、
前記操作部材３０は、錠本体１０の少なくとも左右一方側に位置し、かつ上方に回動することで保持部材を押して第２位置に移動する作動部材を有し、
前記錠が錠受け２０に干渉すると施錠姿勢となると共に、保持部材で保持され、
前記保持部材が第２位置に移動すると錠が解除姿勢となるようにしたことを特徴とするシャッターの錠装置である。
【００１４】
第２の発明は、第１の発明において座板７の錠本体１０の左側と右側に操作部材３０がそれぞれ上下回動自在に取付けられ、
この左右の操作部材３０間に跨って作動部材を取付けたシャッターの錠装置である。
【００１５】
第３の発明は、第１又は第２の発明において保持部材は下方の第１位置と上方の第２位置とに亘って上下移動するスライダー１２で、このスライダー１２は受部を有し、
操作部材３０に設けた作動部材が受部の下面を押しながら摺動するようにしたシャッターの錠装置である。
【００１６】
第４の発明は、第１又は第２の発明において保持部材は下方の第１位置と上方の第２位置とに亘って上下揺動する揺動プレート５０で、この揺動プレート５０は受部を有し
操作部材３０に設けた作動部材が受部の下面を押しながら摺動するようにしたシャッターの錠装置である。
【００１７】
第５の発明は、第２の発明において作動部材は作動ピン３１で、各操作部材３０は端部キャップ３３を有し、その対向した端部キャップ３３の各ピン挿通穴３５に作動ピン３１の両端部分を挿通し、その作動ピン３１の両端部を各ピン挿通穴３５の底部に当接して左右方向に動くことを規制したシャッターの錠装置である。
【００１８】
第６の発明は、シャッター枠１に沿ってシャッタースラット２を昇降自在に設けてシャッター枠１を開放、閉塞するシャッターにおいて、
前記シャッタースラット２の最下部に座板７を取付け、
この座板７に複数の錠本体１０を左右方向に間隔を置いてそれぞれ取付け、前記座板７における各錠本体１０の左側と右側に操作部材３０をそれぞれ上下回動自在に取付け、
前記シャッター枠１の下枠６に複数の錠受け２０を、前記各錠本体１０と対向してそれぞれ取付け、
前記各錠本体１０は、錠と保持部材を有し、
その錠は錠受け２０と係合して施錠する施錠姿勢と離脱して解錠する解錠姿勢とに回動し、前記保持部材は、錠を施錠姿勢で保持する第１位置と、保持を解除する第２位置に移動し、前記錠が錠受け２０に干渉すると施錠姿勢となると共に、保持部材で保持され、前記保持部材が第２位置に移動すると錠が解除姿勢となるもので、
前記隣接した操作部材３０間に跨って、その操作部材３０が上方に回動することで保持部材を押して第２位置に移動する作動部材を取付けたことを特徴とする錠装置を備えたシャッターである。
【００１９】
【作用】
第１の発明によれば、錠本体１０の錠が錠受け２０に係止した施錠状態において、操作部材３０を上方に回動することで解錠されるから、操作部材３０の解錠操作方向がシャッターカーテンを上昇する方向である。
よって、シャッターカーテンの開放操作がやり易い。
また、錠本体１０、錠受け２０の取付け位置は座板７、下枠６の長手方向に制約を受けることがなく、長手方向任意の位置に取付けることが可能である。
また、操作部材３０に設けた作動部材は錠本体１０の保持部材を押して第２位置に移動すれば良いから、この作動部材と保持部材を連結する必要がない。
よって、作動部材によって保持部材に無理な力が作用することがなく、錠本体１０、作動部材を破損する恐れがない。
【００２０】
また、操作部材３０が錠本体１０の少なくとも左右一方側に位置しているから、この操作部材３０が錠本体１０よりも大きく上方に突出しないので、座板７の上下寸法を小さくできる。
【００２１】
第２の発明によれば、左右の操作部材３０が作動部材で連結され、一方の操作部材３０を上方に回動すれば、それに追従して他方の操作部材３０も上方に回動する。
よって、作動部材がスムーズに上方に移動するので、錠本体１０の左側、右側からスムーズに解錠することができる。
また、左右の操作部材３０を上方に回動した時に前述のように作動部材が保持部材を押すだけであるから、錠本体１０を破損する恐れがない。
【００２２】
第３の発明によれば、操作部材３０を上方に回動すると作動部材がスライダー１２の受部の下面を押しながら摺動するから、スライダー１２を下方の第１位置から上方の第２位置にスムーズに移動できる。
【００２３】
第４の発明によれば、操作部材３０を上方に回動すると作動部材が揺動プレート５０の受部の下面を押しながら摺動するから、揺動プレート５０を下方の第１位置から上方の第２位置にスムーズに揺動できる。
【００２４】
第５の発明によれば、作動ピン３１が受部の下面に接するから、その作動ピン３１はスムーズに摺動する。
よって、スライダー１２、揺動プレート５０をよりスムーズに移動、揺動することができる。
また、左右の操作部材３０に設けた端部キャップ３３の各ピン挿通穴３５に作動ピン３１の両端部分を挿通することで、その作動ピン３１が左右方向に動くことを規制できる。
【００２５】
第６の発明によれば、座板７の長手方向に間隔を置いた複数個所を下枠６に施錠するので、防犯性が向上する。
また、複数の操作部材３０は作動部材で連結され、いずれか１つの操作部材３０を上方に回動すれば、他の操作部材３０も上方に回動するので、いずれか１つの操作部材３０を上方に回動すれば各錠本体１０と各錠受け２０がそれぞれ解錠状態となる。
よって、解錠操作性が向上する。
また、座板７の長手方向複数位置が下枠６に係止されるから、座板７は外力によって室外側に向けてたわみ難く、室外から故意に座板７をこじって解錠することがやりづらくなるので、防犯性が向上する。
【００２６】
【発明の実施の形態】
図１に示すように、シャッター枠１と、このシャッター枠１に沿って昇降してシャッター枠１を開放・閉塞するシャッターカーテン２と、前記シャッターカーテン２を巻き取り繰り出しする巻き取り繰り出し部３と、シャッターカーテン２を閉塞状態で施錠する錠装置４でシャッターを構成している。
前記シャッター枠１は左右の縦枠５と下枠６と図示しない上枠を備えている。このシャッター枠１は建物開口部に取付けられる。
この実施の形態では、サッシ枠１は引き違いサッシ窓のサッシ枠を兼用し、シャッター枠１はその室内側部に障子が引き違いに装着できると共に、その室外側部にシャッターカーテン２が昇降自在に設けられ、シャッター付きサッシ窓を形成している。
これに限ることはなく、シャッター枠１とサッシ枠を別々とし、シャッター枠１を建物開口部に直接取付けるようにしても良いし、サッシ枠に取付けても良い。
【００２７】
前記シャッターカーテン２は複数のスラット２ａを連結し、その最下部のスラット２ａに座板（ボトムスラット）７が設けてある。
前記巻き取り繰り出し部３は巻取ドラム８を備え、この巻取ドラム８に最上部のスラット２ａが連結され、その巻取ドラム８でシャッターカーテン２を巻き取り、繰り出しする。
前記巻取ドラム８はシャッターボックス９内に設けられている。
【００２８】
前記錠装置４は、座板７に取付けた錠本体１０と、サッシ枠１の下枠６に取付けた錠受け２０と、座板７に上下回動自在に取付けた操作部材３０を備えている。
この実施の形態では、錠本体１０は座板７の長手方向中間部に取付けてあり、この錠本体１０の左側と右側に操作部材３０が長手方向に沿って上下回動自在にそれぞれ取付けてある。この各操作部材３０は長尺である。
なお、錠本体１０は座板７の長手方向端部寄りに取付けて良く、この錠本体１０の取付け位置は限定されない。また、操作部材３０は錠本体１０の左側又は右側、つまり左右一方側にだけ取付けても良いし、操作部材３０は短尺でも良い。
【００２９】
次に、錠装置４、座板７の具体形状を説明するが、これに限ることはない。
図２、図３、図４に示すように、前記錠本体１０は座板７の室内側部に取付けたベース１１と、このベース１１に設けた保持部材、例えばベース１１に沿って上下動するスライダー１２と、前記ベース１１に施錠姿勢と解錠姿勢とに回動自在に支承した錠、例えば錠鎌（ラッチ）１３と、この錠鎌１３を解錠姿勢に回動付勢する弾性部材、例えばスプリング１４と、錠鎌１３に設けたカム１５を備え、それらはカバー体１６で覆われて見えないようにしてある。
前記スライダー１２はスプリング１４で下方位置に保持される。このスプリング１４は前記スプリング１４と別であっても良い。
前記錠受け２０は、前記錠鎌１３が係脱するピン２１を備えている。
このピン２１はブラケット、例えば上向きコ字状のブラケット２２に室内外側方向に向けて固着してある。このブラケット２２が下枠６に固着してある。例えば、ビス２３で固着してある。
前記ブラケット２２にカバー２４が嵌め込むようにして取付けてあり、このカバー２４でピン２１、ブラケット２２が見えないようにしてある。
【００３０】
前記操作部材３０は錠本体１０の左右側方において座板７に図２に実線で示す下方位置と仮想線で示す上方位置に亘って上下に回動自在に設けてある。好ましくは下方位置の時に錠本体１０よりも上方に突出しないように設けてある。
【００３１】
前記操作部材３０は作動部材、例えば断面円形の作動ピン３１を備え、その作動ピン３１は錠本体１０内部に突出している。例えば、操作部材３０は中空部３２を有し、その中空部３２に端部キャップ３３を嵌合して取付け、この端部キャップ３３に作動ピン３１を嵌合して取付けてある。この作動ピン３１は操作部材３０の長手方向端部よりも突出して錠本体１０の内部に突出している。
この実施の形態においては、錠本体１０の左側、右側にそれぞれ操作部材３０が設けられ、左右の操作部材３０に跨って作動ピン３１が設けられ、左右の操作部材３０は作動ピン３１で連結されている。
前記操作部材３０の室外側部に凹陥部３４を有し、この凹陥部３４を座板７の室内側面７ａに一体的に設けた突起７ｂに長手方向からスライドして嵌め合わせることで上下回動自在に取付けられる。
なお、操作部材３０の座板７への取付けた方はこれに限ることはない。例えば操作部材３０側に突起７ｂを設け、座板７側に凹陥部３４を設けても良いし、ヒンジで上下回動自在に取付けても良い。
【００３２】
次に動作を説明する。
図４に示すように、前記錠鎌１３が解錠姿勢であるとスライダー１２は下方位置であり、その状態で下降すると、錠鎌１３のロック溝１３ａの先端部１３ｂがピン２１に当接し、さらに下降すると錠鎌１３が施錠姿勢に向けて回動し、これと同時に錠鎌１３に設けたカム１５のカム面１５ａがスライダー１２の突起１２ａに接してスライダー１２を上方位置に向けて押し上げる。そして錠鎌１３が施錠姿勢となると図３に示すようにロック溝１３ａがピン２１を係止して施錠すると共に、カム１５が突起１２ａを越え、スライダー１２が下降して下方位置となり、突起１２ａにカム１５の端面１５ｂが干渉して錠鎌１３がスプリング１４で解錠姿勢に回動しないように保持する。
この動作の時にはスライダー１２と作動ピン３１は干渉することがない。
【００３３】
前述の状態で操作部材３０を上方に回動すると作動ピン３１が上方に移動し、スライダー１２の受部、例えば横向片１２ｂの下面に接してスライダー１２を上方に移動する。
前述の状態でスライダー１２が上方に移動すると突起１２ａがカム１５の端面１５ｂと離れ、錠鎌１３がスプリング１４によって解錠姿勢に回動する。
操作部材３０から手を離すと、スライダー１２がスプリング１４で下方に移動して図４に示すように突起１２ａがカム１５のカム面１５ａに当接する。
【００３４】
前述の動作において作動ピン３１は操作部材３０とともに円弧軌跡に沿って上方に移動するが、その作動ピン３１はスライダー１２を、その横向片１２ｂの下面に沿って室内外側方向に摺動しながら押し上げるので、作動ピン３１、横向片１２ｂに無理な力が作用せずに、スライダー１２はスムーズに上方に移動する。
【００３５】
また、左右一方の操作部材３０と左右他方の操作部材３０は作動ピン３１で連結され、一方の操作部材３０を上方に回動すると作動ピン３１を介して他方の操作部材３０も上方に回動するので、錠本体１０の内部に無理な力が作用することがない。
【００３６】
図２にはカバー１６が図示してあるが、図３、図４ではカバー１６の図示を省略して動作を理解し易くしてある。
【００３７】
次に、錠本体１０の各部材を具体的に説明する。
図５に示すように、ベース１１は縦板１１ａと、この縦板１１ａの左右両端部に設けた取付板１１ｂと、縦板１１ａの下端部に設けた横向板１１ｃと、この横向板１１ｃに設けた垂下板１１ｄを備え、その縦板１１ａに上下方向の長孔１１ｅが形成され、垂下板１１ｄにピン挿入溝１１ｆが下面に開口して形成してある。
前記スライダー１２は、縦板１２ｃに前述の横向片１２ｂを室内側（見込み方向）に向けて設け、その縦板１２ｃの一部分を切り起こして前述の突起１２ａとしてある。
このスライダー１２の縦板１２ｃに、図６（ａ），（ｂ）に示すように長孔１１ｅを挿通した固着具、例えばピン１７が固着され、スライダー１２（縦板１２ｃ）はピン１７、長孔１１ｅによってベース１１（縦板１１ａ）に沿って上下動自在に支承される。
なお、スライダー１２の縦板１２ｃに縦長の打ち出し突起１２ｄが形成され、この打ち出し突起１２ｄがベース１１の縦板１１ａに接し、接触面積を小さくしてスムーズに上下摺動するようにしてある。
【００３８】
前記錠鎌１３はピン１８でベース１１の垂下板１１ｄに回動自在に取付けられ、そのロック溝１３ａがピン挿入溝１１ｆと対向するようにしてある。
前記錠鎌１３の上面に横向片１３ｃを介してカム１５が上向きに設けてある。
前記スプリング１４はスライダー１２の横向片１２ｂの穴１２ｅとカム１５に設けた突片１５ｃに亘って取付けられる。
前記カバー体１６は下面と一側面が開口したほぼ箱形状で、左右両側面に切欠き部１６ａがそれぞれ形成してある。
【００３９】
前記錠受け２０のブラケット２２は図７に示すように一対の縦片２２ａと横片２２ｂで上向きコ字形状で、その一対の縦片２２ａの孔２５に跨ってピン２１が固着される。
前記カバー２４は上面と下面が開口したほぼ箱形状で、ブラケット２２の上から嵌め込むようにして取付ける。
このカバー２４の上部開口２６から前記錠鎌１３、垂下板１１ｄが入り込み、ピン２１と係合する。
【００４０】
前記端部キャップ３３は図８と図９に示すように、ピン挿通穴３５を有し、このピン挿通穴３５に作動ピン３１を挿入して取付ける。
このようであるから、図３に示すように左右の操作部材３０に取付けた左右の端部キャップ３３のピン挿通穴３５に作動ピン３１の両端部が挿入され、その左右端面がピン挿通穴３５の底部に当接して左右方向に動かないように固定される。
具体的には、端部キャップ３３は操作部材３０の中空部３２に挿入される本体部３３ａと操作部材３０の端面に接する端面板３３ｂを有し、その本体部３３ａに設けた係止片３６が操作部材３０の係止穴３７に係止して取付けられる。
【００４１】
次に、錠本体１０、操作部材３０の取付け手順を説明する。
前記ベース１１とスライダー１２と錠鎌１３を組み合わせた状態で、図３と図４に示すように、前記座板７の室内側面７ａに形成した下向きの鉤片７ｃの上面にベース１１の取付板１１ｂの横片１１ｂ−１を接し、その横片１１ｂ−１にビス１９で固着して取付ける。
この鉤片７ｃの上面には図４に示すように開口部７ｄが形成され、この開口部７ｄから垂下板１１ｄ、錠鎌１３が下方に突出する。
この状態で作動ピン３１を端部キャップ３３のピン挿通穴３５に挿入してピン挿通穴３５の底部に当接して取付けた左右一方の操作部材３０を前述のように左右一側方から取付けると共に、この作動ピン３１をスライダー１２の横向片１２ｂの下方に位置させる。
そして作動ピン３１が取付けられていない他方の操作部材３０を左右他側方から取付けると共に、他方の操作部材３０に取付けられた端部キャップ３３に横向片１２ｂの下方に位置した前記作動ピン３１を挿入してピン挿通穴３５の底部に当接して作動ピンが左右方向に動かないように固定する。
この後に、カバー体１６を押し込んで座板７の室内側面７ａと鉤片７ｃの上面に接して取付ける。カバー体１６の切欠き部１６ａに作動ピン３１が挿通する。
【００４２】
左右の操作部材３０の左右方向（長手方向）の動きは、錠本体１０と図１に示す座板７の室内側面７ａにおける左右端部に取付けたストッパ４０で規制する。
【００４３】
図１０と図１１に示すようにして左右の操作部材３０に作動ピン３１を左右方向に動かないように固定しても良い。
つまり、各操作部材３０をピン挿通孔、例えば断面ほぼ半円形の凹部３８を長手方向に連続して有する形状とし、この対向した凹部３８に作動ピン３１の両端部分を挿入すると共に、その各凹部３８の一部分３８ａを打ち込み変形して作動ピン３１の端部が当接するストッパとする。
この場合には操作部材３０の端部に小口キャップ３９を取付ける。
このようにすれば、操作部材３０が長手方向に同一断面で、操作部材３０をアルミ押出し形成を利用できる。
【００４４】
前述の実施の形態では作動ピン３１を左右の操作部材３０間に跨って取付けしたが、図１２に示すように左右の操作部材３０にそれぞれ作動ピン３１を取付け、各作動ピン３１をスライダー１２の横向片１２ｂの下方にそれぞれ位置させても良い。
この場合には、左右一方の操作部材３０を上方に回動して解錠した時に、他の操作部材３０は上方に回動しない。
【００４５】
また、図１３に示すようにスライダー１２の左右端部にガイド縦片１２ｆをそれぞれ設け、この各ガイド縦片１２ｆをベース１１の左右の取付板１１ｂの縦片１１ｂ−２に接してスライダー１２が左右に振れ動かずにスムーズに上下動するようにしても良い。
【００４６】
前記各実施の形態では錠本体１０の保持部材をスライダー１２としたが、図１４に示すように揺動プレート５０としても良い。
具体的には、ベース１１（縦板１１ａ）に揺動プレート５０をピン５１で上方位置と下方位置に亘って上下揺動自在に取付ける。この揺動プレート５０は突起５０ａと受部、例えば横向片５０ｂを有し、その横向片５０ｂとカム１５の突片１５ｃに亘ってスプリング１４を取付けることで錠鎌１３を解錠姿勢に回動付勢し、かつ揺動プレート５０を下方位置に回動付勢する。
そして、図１４に示すようにカム１５の端面１５ｂが突起５０ａに当接することで錠鎌１３を施錠姿勢で保持し、操作部材３０に設けた作動ピン３１は揺動プレート５０の横向片５０ｂの下方に位置し、操作部材３０が上方に回動して作動ピン３１が上方に移動すると横向片５０ｂを押して揺動プレート５０を図１４に仮想線で示すように上方に揺動して上方位置とし、その突起５０ａがカム１５の端面１５ｂから離れるようにする。
【００４７】
すなわち、保持部材は錠鎌１３（錠）を施錠姿勢で保持する第１位置（下方位置）と保持を解除する第２位置（上方位置）に移動自在で、常時第１位置であると共に、作動ピン３１で押されて第２位置となるものであれば良い。
【００４８】
また、錠は錠鎌１３に限ることはないし、錠受け２０はピン２１に限ることはなく、錠が常時解錠姿勢で錠受け２０に干渉することで施錠姿勢に向けて回動し、かつ保持部材を第１位置に移動して施錠姿勢となるものであれば良い。好ましくは保持部材が第１位置に移動するものであれば良い。
また、作動部材は断面円形の作動ピン３１に限ることはなく、断面矩形、多角形などの作動ピン、プレート形状、ブロック形状などでも良い。つまり、作動部材は前述の保持部材を押して第２位置に移動するものであれば良い。

The movement of the left and right operating members 30 in the left and right direction (longitudinal direction) is regulated by stoppers 40 attached to the left and right ends of the lock body 10 and the indoor side surface 7a of the seat plate 7 shown in FIG.
[0043]
As shown in FIGS. 10 and 11, the operating pin 31 may be fixed to the left and right operation members 30 so as not to move in the left and right direction.
In other words, each operating member 30 is formed into a shape having a pin insertion hole, for example, a concave portion 38 having a substantially semicircular cross section in the longitudinal direction, and both ends of the operating pin 31 are inserted into the opposed concave portion 38 and each concave portion is formed. A portion 38a of the 38 is driven and deformed to serve as a stopper with which the end of the operating pin 31 abuts.
In this case, the small cap 39 is attached to the end of the operation member 30.
In this way, the operating member 30 has the same cross section in the longitudinal direction, and the operating member 30 can be formed by extruding aluminum.
[0044]
In the above-described embodiment, the operation pins 31 are attached across the left and right operation members 30. However, as shown in FIG. 12, the operation pins 31 are attached to the left and right operation members 30, respectively, and each operation pin 31 is attached to the slider 12 It may be located below the horizontal piece 12b.
In this case, when one of the left and right operation members 30 is rotated upward to unlock, the other operation members 30 do not rotate upward.
[0045]
As shown in FIG. 13, guide vertical pieces 12 f are provided at left and right ends of the slider 12, and the guide vertical pieces 12 f are brought into contact with the vertical pieces 11 b-2 of the left and right mounting plates 11 b of the base 11 so that the slider 12 is moved. You may make it move up and down smoothly without swinging to the left and right.
[0046]
Although the slider 12 is used as the holding member of the lock main body 10 in each of the above embodiments, it may be a rocking plate 50 as shown in FIG.
Specifically, the swing plate 50 is attached to the base 11 (vertical plate 11a) with pins 51 so as to be vertically swingable over an upper position and a lower position. The swinging plate 50 has a projection 50a and a receiving portion, for example, a lateral piece 50b, and the spring 14 is mounted over the lateral piece 50b and the protruding piece 15c of the cam 15 to rotate the locking sickle 13 to the unlocking position. The swing plate 50 is urged and the swing plate 50 is urged to rotate downward.
Then, as shown in FIG. 14, the end face 15b of the cam 15 abuts on the projection 50a to hold the lock sickle 13 in the locked position, and the operating pin 31 provided on the operation member 30 is moved to the side of the horizontal piece 50b of the swing plate 50. When the operating member 30 is rotated upward and the operating pin 31 is moved upward, the horizontal plate 50b is pushed to swing the swing plate 50 upward as shown by the imaginary line in FIG. And the projection 50a is separated from the end face 15b of the cam 15.
[0047]
That is, the holding member is freely movable between a first position (lower position) for holding the locking sickle 13 (lock) in the locking posture and a second position (upper position) for releasing the holding, and is always in the first position and is in operation. What is necessary is just to be pushed to the 2nd position by the pin 31.
[0048]
Further, the lock is not limited to the lock sickle 13, and the lock receiver 20 is not limited to the pin 21, and the lock rotates toward the locking position by interfering with the lock receiver 20 in the always unlocked position, and What is necessary is just to be able to move the holding member to the first position to be in the locked posture. Preferably, the holding member may move to the first position.
The operating member is not limited to the operating pin 31 having a circular cross section, but may be an operating pin having a rectangular or polygonal cross section, a plate shape, a block shape, or the like. That is, the operating member may be any member that pushes the above-described holding member and moves to the second position.
[0049]
Next, an embodiment of a shutter using the lock device 4 according to the present invention will be described.
As shown in FIG. 15, a plurality of lock bodies 10, for example, three lock bodies 10 are mounted on the seat plate 7 at intervals in the longitudinal direction, and a lock receiver 20 is formed on the lower frame 6 so as to face each lock body 10. Install at intervals in the direction.
An operation member 30 is attached to the seat plate 7 on the left and right sides of the lock body 10 so as to be vertically rotatable.
[0050]
Then, as shown in FIG. 16, operation pins 31 (operation members) are attached to the adjacent operation members 30 to connect the operation members 30 to each other. The (holding member) is pushed to move upward (moving to the second position).
For example, the operation pin 31 is located below the horizontal piece 12b (receiving portion) of the slider 12 (holding member).
[0051]
【The invention's effect】
According to the first aspect of the invention, in the locked state where the lock of the lock body 10 is locked to the lock receiver 20, the operation member 30 is unlocked by rotating the operation member 30 upward. The operation direction is the direction in which the shutter curtain is raised.
Therefore, the shutter curtain is easily opened.
Further, the mounting positions of the lock main body 10 and the lock receiver 20 are not restricted by the longitudinal directions of the seat plate 7 and the lower frame 6, and can be mounted at arbitrary positions in the longitudinal direction.
Further, since the operating member provided on the operating member 30 only needs to press the holding member of the lock body 10 and move to the second position, there is no need to connect the operating member and the holding member.
Therefore, no excessive force acts on the holding member by the operating member, and there is no possibility that the lock body 10 and the operating member are damaged.
[0052]
Further, since the left and right operation members 30 are located on at least one of the left and right sides of the lock main body 10, the operation members 30 do not protrude larger than the lock main body 10, so that the vertical dimension of the seat plate 7 can be reduced.
[0053]
According to the invention according to claim 2, the left and right operating members 30 are connected by the operating member, and if one operating member 30 is turned upward, the other operating member 30 is also turned upward following the operation. .
Therefore, since the operating member moves smoothly upward, the lock can be smoothly unlocked from the left and right sides of the lock body 10.
In addition, when the left and right operation members 30 are rotated upward, the actuating member only pushes the holding member as described above, so that there is no possibility of damaging the lock body 10.
[0054]
According to the third aspect of the present invention, when the operating member 30 is rotated upward, the operating member slides while pressing the lower surface of the receiving portion of the slider 12, so that the slider 12 is moved from the lower first position to the upper second position. Can move smoothly to the position.
[0055]
According to the invention according to claim 4, when the operating member 30 is rotated upward, the operating member slides while pressing the lower surface of the receiving portion of the swing plate 50, so that the swing plate 50 is moved from the lower first position. It can swing smoothly to the upper second position.
[0056]
According to the fifth aspect of the present invention, since the operating pin 31 contacts the lower surface of the receiving portion, the operating pin 31 slides smoothly.
Therefore, the slider 12 and the swing plate 50 can be moved and swing more smoothly.
In addition, by inserting both ends of the operating pin 31 into the respective pin insertion holes 35 of the end caps 33 provided on the left and right operation members 30, the movement of the operating pin 31 in the left-right direction can be restricted.
[0057]
According to the invention according to claim 6, since a plurality of locations spaced apart in the longitudinal direction of the seat plate 7 are locked to the lower frame 6, the security is improved.
The plurality of operating members 30 are connected by an operating member, and if one of the operating members 30 is rotated upward, the other operating members 30 are also rotated upward. If it rotates upward, each lock main body 10 and each lock receiver 20 will be in an unlocked state, respectively.
Therefore, unlocking operability is improved.
Further, since a plurality of positions in the longitudinal direction of the seat plate 7 are locked to the lower frame 6, the seat plate 7 is unlikely to bend toward the outdoor side due to an external force, so that the seat plate 7 can be deliberately twisted and unlocked from the outdoor side. Since it is difficult to do so, crime prevention is improved.
