Description

【0001】
【発明の属する技術分野】
本発明は、シャッターの施錠装置に関する。
【0002】
【従来の技術】
シャッターの施錠装置の一つの形態として、特開平8−109780号公報に開示されているようなものがある。この施錠装置は、シャッターを昇降案内するガイドレールの下端にラッチ掛りを設け、シャッター下端部の座板の両側にラッチ掛りと係合するラッチ体を設け、シャッターを閉鎖すると自動的にラッチ体がラッチ掛りに係止して施錠される。また、座板にはラッチ体の係止を解くための解除レバーを、シャッターカーテンを開放するための引き手を兼ねるように座板の長手方向に沿って設けてあり、この引き手を持ってシャッターカーテンを上げれば、自動的に施錠が解除されてシャッターを開放できる。
【0003】
【発明が解決しようとする課題】
上記の施錠装置は、施錠と解錠をいちいち行う必要がなく、とても便利なものであったが、解除レバーを設けた屋内側でしか解錠できない。つまり、従来のこの手の施錠装置を備えるシャッター装置は、屋外側からシャッターを開けることができなかった。
【0004】
本発明は、この欠点を克服し、操作性と防犯性に優れたシャッターの施錠装置を提供することを目的とする。
【0005】
【課題を解決するための手段】
上記の課題を達成するために、本発明によるシャッターの施錠装置は、シャッターとシャッターのガイドレールとの間に設けてあり、閉鎖したシャッターを自動的に施錠するロック機構と、シャッターの屋内側に回動自在に設けてあり、回動操作により施錠を解除する解錠部材と、シャッターの屋外側に設けてあり、キー操作により押し込み可能な状態と押し込み不可能な状態に切り替えることのできる解錠ボタンとを備え、解錠ボタンは、シャッターを貫通して解錠部材に当接可能に設けてあり、押し込まれた解錠ボタンが解錠部材を押動し、解錠部材が施錠を解除する位置まで回動することを特徴とする。
【0006】
【発明の実施の形態】
以下、本発明の実施の形態を図面に基づいて説明する。図1は、本発明による施錠装置を備えるシャッター装置を、屋外側から見た正面図である。このシャッターの施錠装置は、シャッター1の最下部に設けた座板6とシャッターのガイドレール2との間に、シャッター1を閉鎖した時に自動的に施錠するロック機構3を備えており、座板6の屋内側の面には、ロック機構3の施錠を解除するための解錠部材4を有する。また、シャッター1の屋外側には、解錠部材4を動作させてロック機構3の施錠を解除できる屋外側解錠部材7を有する。
【0007】
まず、図4と図5に即して、ロック機構3の仕組みについて述べる。ロック機構3は、座板6の屋内側の面の左右両側に設けたラッチ体8と、ガイドレール2に設けたラッチ掛り9とから成る。両側のロック機構3は左右対象であり、以下は左側のものについて説明する。ラッチ体8は、鉄板を二重に折り曲げて形成したホルダー10に、係止金具11とストッパー金具12をピン13,14で回転可能に軸支してある。係止金具11は、ガイドレール2側に二股に形成した係止溝15を有し、反対側にストッパー金具12のための第一、第二の二つの係止部16,17を有する。ストッパー金具12には、係止金具11の係止部16,17に係止する爪部18と、ホルダー10の外側に下方に向けて斜めに伸びる解除レバー19を有する。係止金具11とストッパー金具12の上部には板バネ20を渡してあり、係止金具11が左回り、ストッパー金具12が右回りに付勢してある。ラッチ掛り9は、断面コの字形のベース体21に係止軸22を架け渡したもので、シャッター1を閉鎖した時に、ベース体21の間にラッチ体8が進入する位置に、ガイドレール2に固定してある。なお、図中の23はシャッタースラットとの連結部であり、24はゴム製のクッションである。
【0008】
シャッター1を開けた状態では、ラッチ体8は図4(ロ)の状態となっており、係止金具11の係止溝15が下方に向けて開口し、第一係止部16にストッパー金具12の爪部18が係止している。シャッター1を下ろしてくると、係止溝15にラッチ掛り9の係止軸22が進入し、係止金具11が右回りに回転し、係止溝15が真横を向いたところで、第二係止部17に爪部18が係止してロックが掛かり、図4(イ)に示すように、係止溝15に係止軸22が係止して施錠される。このように本ロック機構3は、シャッターを閉鎖することで、自動的に施錠される。施錠を解除するには、ストッパー金具12を左回りに僅かに回転させることで、爪部18が第二係止部17から外れて係止金具が左回りに回転して図4(ロ)の状態に復帰し、施錠が解除される。
【0009】
施錠の解除を行うのは、座板6の屋内側に設けた解錠部材4である。解錠部材4は、座板6の長手方向に沿った横長の部材で、上部に形成した連結部25に、座板6に突設した取付片26を嵌合させて回動自在に取り付けてある。なお、連結部25と取付片26の間には、図示しない捩りバネを介在してあって、解錠部材4は下向きに付勢してある。解錠部材4の左右両側の下部には解除バー27が突出しており、解除バー27は、ストッパー金具12の解除レバー19の内側に伸びている。解錠部材4は、屋内側からシャッター1を上げる際の把手を兼ねており、解錠部材4の下部に手を掛けてシャッター1を上げようとすると、図5(ロ)に示すように、解錠部材4が上方に向けて回動し、解除バー27が解除レバー19を押し上げてストッパー金具12を左回りに回転させるから、先に述べた通りロック機構3の施錠が解除されることとなる。
【0010】
座板6の屋外側の面には、図2に示すような屋外側解錠部材7を設けてある。屋外側解錠部材7は、座板6に固定したケース体28に、シリンダー錠29と解錠ボタン5を横並びに有する。ケース体28には、下部に把手30を一体に形成してある。解錠ボタン5は、先端部が座板6を貫通して屋内側に突出しており、解錠ボタン5を押し込むと、図3(ロ)に示すように、屋内側の解錠部材4が上方に向けて回動し、先に述べたロック機構3の施錠を解除できるようになっている。また解錠ボタン5は、バネ31によって屋外側に突出する状態に付勢されている。シリンダー錠29は、鍵孔32にキーを差し込んで回すことでデッドボルト33が解錠ボタン5に出没し、解錠ボタン5を押し込み可能な状態と押し込み不可能な状態とに切り替えることができる。押し込み不可能な状態となっていれば、屋外側からシャッターを開けることはできない。
【0011】
本発明のシャッターの施錠装置は以上のような構成となっており、シャッター1を閉めると自動的に施錠され、シャッター1を開ける時は、屋内側からであれば解錠部材4に手を掛けて回動するだけで解錠でき、屋外側からであれば、シリンダー錠29を操作して、押し込み可能な状態にした解錠ボタン5を押し込むことで解錠できる。なお解錠ボタン5は、押し込み操作部とシャッター貫通部と解錠部材当接部とが連動して動くものであれば、必ずしも一体成形されたものである必要はなく、形状や構成は適宜変更できる。
【0012】
本発明のシャッターの施錠装置は、以上に述べた実施形態に限定されない。ロック機構の詳細な構造は若干異なっていても良い。また、上下方向に開閉するシャッターに限らず、横方向に開閉するシャッターに利用することもできる。屋内側に設ける解錠部材は、例えば横方向に開閉するシャッターの場合には、垂直軸回りに回動自在に設けることとなり、シャッターの開閉方向に応じて回動方向が変更される。
【0013】
【発明の効果】
本発明によるシャッターの施錠装置は、シャッターを閉鎖すると自動的に施錠されるので、鍵を掛け忘れることがない。屋内側からは解錠部材を回動させることで簡単に解錠でき、屋外側からも解錠ボタンを押し込むことで解錠できる。解錠ボタンは、キー操作により押し込み不可能な状態にできるので、防犯性が確保されている。また、屋内側と屋外側の解錠部材は互いに連携させてあり、別々に設けるよりも安上がりである。
