【発明の属する技術分野】
本発明は電気錠の切換え装置に関する。本発明は、電気錠の作動モード（非通電時施錠型か、それとも通電時施錠型かに切換えること）と電気錠の内外の操作部材態様（例えばレバーハンドルの回動操作を自由にするか、それとも不自由にすること）を切換えることができることを特徴とする電気錠の切換え装置に関する。
【０００２】
【従来の技術】
従来、電気錠は建物の扉に取り付けられているが、住居用、商業用、福祉施設用など建物の用途如何によって、非通電時施錠型か、それとも通電時施錠型か、何れかの錠前を選択して取り付けている。また電気錠は、非通電時施錠型であれ或いは通電時施錠型であれ、例えばホテルの各部屋の扉に取り付ける場合には、アンチパニック機能（サムターンを操作しなくても内側操作部材の操作のみで扉を開けることができること。）を有することが望ましいので、室内からサムターンを操作しなくても、レバーハンドルの回動操作のみで扉を開くことができる電気錠を取り付けることが多い。一方、養老ホーム、公共的施設などの建物の扉に取り付ける場合には、防災時を考慮し、部屋の外からシリンダーのキー操作をしなくても外側操作部材の操作のみで扉を開けることができることが望ましい。そこで、そのようなタイプの電気錠が取り付けられている。このように電気錠は、現在、様々な型式のものが存在し、建物の用途別に選択されている。
【０００３】
ところで、ある建物の扉に非通電時施錠型を装着した場合に於いて、当該電気錠を通電時施錠型に作動モードを換えたい時がある。また、建物の用途変更に対応して当該電気錠の内外操作部材の態様も変えたいという場合もある。このような場合、従来の電気錠では、扉に一旦取り付けた電気錠を所望する型式の電気錠と交換せざるを得ないという問題点があった。そこで、一つの電気錠で作動モードと内外の操作部材の態様を自由に切換えることが可能な電気錠の切換え装置が要望されている。
【０００４】
【発明が解決しようとする課題】
本発明の第１の目的は、一つの電気錠で作動モードと内外の操作部材の態様を自由に切換えることが可能な電気錠の切換え装置を提供することである。第２の目的は、錠箱からフロント板を取り外すだけで、電気錠の作動モード及び／又は内外の操作部材の態様を簡単に切換えることができることである。第３の目的は、各作動部材を合理的に組み合わせ、錠箱内のスペースを有効的に活用することができることである。第４の目的は、レバー状の切換え手段を切換える時に「クリック感」を得ることができることである。第５の目的は、錠箱のコンパクト化を図るために各部材をそれぞれ枢支する左右の軸同志の間隔を狭めても、例えば内側切換え手段の切換え力が内側操作部材用の内側の駆動カムまで伝わることである。第６の目的は、デッドボルトをスムースに案内することができることである。
【０００５】
【課題を解決するための手段】
本発明の電気錠の切換え装置は、錠箱錠箱３内に、少なくとも複数個の切換え手段と、内外の操作部材７，６によりそれぞれ回動する内外の駆動カム２０，２１と、これら内外の駆動カムとそれぞれ係脱する内外操作部材用のロック手段３５，３６とをそれぞれ設け、前記複数個の切換え手段は、前記錠箱３のフロンド板４或いは開口を有する裏板１１近くに横設された一つの枢軸１８に併設状態に設けられた、内側の操作部材用の前記ロック手段３５のロック態様を切換えるレバー状の内側切換え手段５１と、外側の操作部材用の前記ロック手段３６のロック態様を切換えるレバー状の外側切換え手段５２と、電気錠の作動モードを非通電時施錠型か、それとも通電時施錠型かに切換えるレバー状の作動モード切換え手段６５であることを特徴とする。
【０００６】
上記構成に於いて、錠箱３内に、少なくとも内側切換え手段５１と係合する内側係合作動レバー５６と、この内側係合作動レバー５６と係合するように中央軸４３に軸支され、かつ、第１係合部４６と第２係合部４７とを有する内側の係合アーム４１と、この内側の係合アーム４１と係合し、かつ、該内側の係合アームの回転によって内側の駆動カム２０と係脱するように錠箱にスライド自在に設けられた内側操作部材用のロック手段３５とがそれぞれ配設されていることを特徴とする。
【０００７】
また本発明の電気錠の切換え装置は、錠箱３内の開口１１ａを有する裏板１１近くに横設された一つの枢軸１８に、内側の操作部材のロック態様を切換えるレバー状の内側切換え手段５１と、外側の操作部材のロック態様を切換えるレバー状の外側切換え手段５２とを設け、一方、錠箱３内にフロント板４や裏板１１の案内窓１２に臨むようにデッドボルト５用の案内部材を固定し、該案内部材には前記内外の切換え手段５１，５２の各変位部５１ｄ，５１ｄの先端部に設けた各係合爪５５，５５がそれぞれ摺接係合するクリック感用突起１３ｄを設けたことを特徴とする。
【０００８】
上記構成に於いて、一つの枢軸１８に電気錠の作動モードを非通電時施錠型か、それとも通電時施錠型かに切換えるレバー状の作動モード切換え手段６５とを併設状態に設け、この作動モード切換え手段６５の変位部６５ｄの先端部にも、案内部材のクリック感用突起１３ｄと摺接係合する係合爪６８を形成したことを特徴とする。
【０００９】
【発明の実施の形態】
図１乃至図２１に基づいて一実施例を説明する。図１は電気錠１の外観を示す。図２は扉２の自由側端部に形成された錠箱用空洞に電気錠１を収納した場合に於いて、フロント板の一部を切欠、かつフロント板側から見た説明図である。まず図１及び図２を参照に本発明の環境部材を説明する。電気錠１の錠箱３は、普通一般に一側開口のケース身３ａとケース蓋３ｂとから成り、ケース身３ａには後述する各部材が組み込まれる。４はフロント板、５はデッドボルト、ラッチボルトなどの施錠片、６は外側の操作部材（ノブ，レバーハンドル）、７は内側の操作部材（ノブ，レバーハンドル）、８はキー操作によって施・解錠するシリンダー、９はサムターンである。
【００１０】
次に図３乃至図１４を参照に本発明の主要部について説明する。まず、本発明の錠前は、電気錠１であることが前提である。普通一般に「電気錠」とは、電気的に施錠片を施・解錠操作する錠前のことをいう。
【００１１】
したがって、本発明の電気錠１も、特に図示しないが、離れた場所から制御回路により電気的に錠箱３に内装された駆動源（例えばマイクロモータ）を起動し、該駆動源の駆動力によって錠箱３内の各部材（歯車、ロック片など）を作動させて施錠片５用のロック部材１０のロック状態を解消させることができる。なお、サムターンやシリンダーを操作した後に内外の操作部材をそれぞれ回すこともできる。
【００１２】
以下、本発明の電気錠の切換え装置Ｘの特定事項を中心に説明し、付随的な構成要件については図示や説明を割愛する。まず、図３で示すように錠箱３はフロント板４の裏面に固定的に接合する裏板１１、固着具などを介して扉２に固定される。この錠箱３内には、電気錠の切換え装置Ｘを構成する各部材が内装される。裏板１１の下部には、後述する複数個のレバー状切換え手段の自由端部が臨む開口１１ａが形成されている。
【００１３】
次に、施錠片としてのデッドボルト５（通称、「デッド」）は、フロント板４或いは裏板１１を基準に出没自在に進退動する。デッドボルト５は、図示しない戸枠側のストライクと係脱する。
【００１４】
デッドボルト５は水平状態で進退動する時、フロント板４や裏板１１の案内窓１２に臨むようにケース身３ａに固定された合成樹脂製第１案内板１３（図４参照）と、該第１案内板１３に接合状態に合体するケース蓋３ｂ側の合成樹脂製の第２案内板１４（図５参照）とに案内される。本実施例の案内部材は、第１案内板１３と第２案内板１４とを一体的に結合すると、デッドボルト５の左右の垂直壁面と摺接する角筒状部材となる。
【００１５】
デッドボルト５は前記案内窓１２を基準として突出する先端部側５ａと、この先端部側５ａに連設する後端部側５ｂと、この後端部側５ｂからケース身の後壁側へと延びる長杆部５ｃと、後端部の下部側に固定された鉤状片５ｄと、一方、後端部の上部側に固定されたＬ型係合片５ｅとから成る。
【００１６】
１５はケース身３ａの中央部に固定されたアングル状の第３案内板で、この第３案内板１５は前記長杆部５ｃを案内するガイド機能を有すると共に、長杆部５ｃに巻装されたデッドバネ１６の後端部を受けるバネ受け機能を有している。デッドボルト５はデッドバネ１６のバネ力に抗して後退する。
【００１７】
ここで、図４乃至図７を参照にして前記第１案内板１３と第２案内板１４の構成を説明する。図４は第１案内板１３である。第１案内板１３は、ケース蓋３ｂ、デッドボルト５、取付け筒１７、枢軸１８など他の組み合わせ部材を取り外した時に全体的な形状が見える。
【００１８】
図４に於いて、１３ａはケース身３ａの内壁面に固定されるベース板本体で、特に要部の形状のみ図示している。このベース板本体１３ａは、ケース身３ａに固定されると垂直状態になる。１３ｂはベース板本体３ａの中央部に交差状態に連設するデッド下面案内壁で、このデッド下面案内壁１３ｂの一端部（右端部）には、ケース蓋３ｂ方向に所要量延伸するオス嵌合突起１３ｃが設けられている。
【００１９】
１３ｄはオス嵌合突起１３ｃに連設して設けられた端面Ｖ時型のクリック感用突起である。このクリック感用突起１３ｄもデッド下面案内壁１３ｂの一端部から突出しているが、前記オス嵌合突起１３ｃよりもケース蓋方向への突出量は少ない。しかし、クリック感用突起１３ｄは、後述する内外の切換手段５１，５２との係合関係を得るために、デッド下面案内壁１３ｂの下面より逆山形状に所要量突出している。
１３ｅはデッド上面案内壁で、このデッド上面案内壁１３ｅはベース板本体１３ａの適当な端部にデッド下面案内壁１３ｂに対して所定間隔離間して設けられている。なお、１３ｆはメネジを有する取付け筒１７用貫通孔、１３ｇは枢軸１８用の軸孔である。
【００２０】
一方、図５は第２案内板１４である。この第２案内板１４は、本実施例では第１案内板１３とは別部材である。しかし、図６で示すように両部材１３，１４は互いに対向的に接合してデッドボルト５を案内する機能、デッドボルト５を所定位置で止めるストッパー機能などを果す。図５に於いて、１４ａは板状の蓋部、１４ｂは蓋部の他端部（左端部）に突出された差込端部で、この差込端部１４ｂは前述した裏板１１の案内窓１１ａに入り込み、デッドボルト５の側面と摺接して該デッドボルトの横揺れを防止する。
１４ｃは蓋部の一端部（右端部）側に形成されたメス嵌合孔で、このメス嵌合孔１４ｃには前述したオス嵌合突起１３ｃが嵌合する。なお、１４ｆはメネジを有する取付け筒１７用貫通孔、１４ｇは枢軸用軸孔である。
【００２１】
次に電気錠の切換え装置Ｘを構成する主な部材について説明する。なお、本発明の実施例に於いて、錠箱３内に対称的に配設される内外の部材に関しては、同一名称の部材が出てくる。そこで部品図については、説明の便宜上、一方の部材の部品のみ示し、他方の部材の図示や説明を割愛する場合がある（機能上同一の部分には、同一の符号を付す）。
【００２２】
図３に於いて、２０は内側の操作部材７の回転操作により回る内側駆動カムである。これに対して２１は外側の操作部材６の操作により回る外側駆動カムである。切換え装置Ｘは、内外の操作部材７，６によりそれぞれ回動する内外の駆動カム２０，２１を備えている（図８参照）。
【００２３】
図８は内側駆動カム２０の一例を示す正面図である。図８で示す符号２３を、ここでは内側操作部材７用の操作軸とする。そこで、２４は操作軸用の軸孔、２５は段差状の操作軸２３が嵌合する環状の連結筒、２６は連結筒から半径方向に突出する幅広（親指の関節形状）の第１カム部である。２７は係合切欠２８を形成するように連結筒から突出する幅狭（指関節形状）の第２カム部で、この第２カム部２７は、第１カム部２６の一辺と対向する。２９は右の人差し指を上方に向けるように連結筒から突出する押圧部で、この押圧部２９は長板形状の連動部材（リトラクター）３０の中央部の側辺と摺接する（図３参照）。
【００２４】
なお、外側駆動カム２１は、図３を基準にすると、内側駆動カム２１の背面側に係合切欠２８を「１０時の方向」に向けた状態で、かつ、操作軸２３と同軸上に配設されている。そして、内側操作部材７を回すと手前側の内側駆動カム２０が独立に回転し、一方、外側操作部材６を回すと奥側の外側駆動カム２１が独立に回転するように軸に支承されている。
【００２５】
前記連動部材３０は、内外の駆動カム２０，２１と係合するように錠箱３に軸支されて、かつ、駆動カムに押されて戸枠側のストライクに係合している施錠片５を引き戻す。
【００２６】
しかして、連動部材３０の下端部は、図３で示すように錠箱３に横設された横軸３１に軸支され、一方、その上端部３０ａはデッドボルト５の後端部５ｂに長杆部５ｃを介して連結或いは係合している。
【００２７】
３５，３６は内外の駆動カム２０，２１とそれぞれ係脱するように錠箱３に摺動自在に設けられた内外操作部材（直接的には駆動カム）用のロック手段である。ここでは符号３５を内側操作部材用のロック手段、一方、符号３６を外側操作部材用のロック手段とする。上下に対称的に配設されるロック手段３５，３６は、図９で示すようにそれぞれ矩形状に形成され、かつ、錠箱３に斜め方向に形成された上下一対の案内部（開口、溝、切欠など）３７，３７にそれぞれスライド自在に嵌め込まれている。
【００２８】
図９は下方に位置する内側操作部材用のロック手段３５の底面図（ケース身の底壁から１０時方向に見た図）である。しかして、３８は中央部に形成された長孔状の係合切欠部で、この係合切欠部３８には、次に説明する内側係合アーム４１の第１係合部側の小突４８が係合する。
【００２９】
さて、４１，４２は内外のロック手段３５，３６のロック状態をそれぞれロック解除の状態に切換えることができるように中央軸４３を介して軸支された内外の係合アームである。ここでは符号４１を内側の係合アームとし、これと対称的に錠箱３に軸支されたそれを外側の係合アーム４２とする。中央軸４３は、ケース身３ａの下部の中央部に固定的に横設されている。
【００３０】
図１０は内側の係合アーム４１、ロック手段３５等を正面（ケース蓋）側から見た説明図である。この図１０を基準に説明すると、４５は中央軸４３に嵌着する軸受け部、４６は軸受け部から右下に挟み状に突出する第１係合部、４７は軸受け部４６から左へと延設された腕状の第２係合部である。
【００３１】
しかして、前記挟み状第１係合部４６の一つ（右側）には米粒状の小突起４８が形成されている。また前記第２係合部４７は下向き湾曲状に形成されている。なお、外側の係合アーム４２は、内側の係合アーム４１とは対称的に中央軸４３に装着されるので、その湾曲状第２係合部は上向きとなる（図３参照）。
【００３２】
前記中央軸４３にはバネ部材５０が巻装され、このバネ部材５０の一端部は、内外の係合アーム４１，４２に適宜に圧接し（他端部は、他の部材に受止めされている。）、かつ、内外の係合アームを一方向に付勢している。本実施例では、内側の係合アーム４１はバネ部材５０のバネ力により常時反時計方向に、一方、外側の係合アーム４２はバネ部材５０のバネ力により常時時計方向に付勢されている。
【００３３】
図１１は切換え手段５１，５２の一例を示す。５１，５２は、前述した一つの枢軸１８（同軸上、正面視方向或いは軸方向）に併設状態に軸支された内外の操作部材態様用切換え手段である。枢軸１８は裏板１１の下部に形成した開口１１ａ付近に位置し、かつ、前述した中央軸４３よりも上方に位置するようにケース身３ａに横設されている。本実施例では、枢軸１８を基準といると、中央軸４３は下方にフオセットした位置にある。つまり、枢軸１８と中央軸４３は、同一水平ライン上に位置していない。これは錠箱３内の恒常的スペースを有効活用するためである。
ここでは符号５１を内側の切換え手段、符号５２を外側の切換え手段とする。図１１から明らかなように、内外のレバー状切換え手段５１，５２は同一形状である。なお、内外のレバー状切換え手段５１，５２は作用や機能が同じであれば、その形状は異なるものであっても良い。
【００３４】
内外のレバー状切換え手段５１，５２は、後述する内側と外側の係合作動レバー５６，５６をそれぞれ介して内外係合アーム４１，４２に間接的に係合している。図１１は内外の切換え手段５１，５２を並べて示した正面図である。説明の便宜上、一方のみを説明する（他方の各部位には同一の符号を付す）。
５１ａは軸孔を有する中心部、５１ｂは中心部から裏板１１の開口１１ａに向かって延伸する先端部、５１ｃは中心部からケース身の後壁側（連動部材の中央部）に向かって延伸する後端部である。
【００３５】
しかして、本実施例では、前記先端部５１ｂには「クチバシ状」の小さな水平溝５３が形成され、該水平溝５３には図示しない小さなドライバー（工具）の先端部が係合可能である。また前記後端部５１ｃには、上方に多少の間隙５４を有して中心部５１ｂへと延びる細幅の変位部５１ｄが連設している。そして、変位部５１ｄの先端部には、第１案内板１３のクリック感用突起１３ｄと摺接係合する山形状の係合爪５５が形成されている。
【００３６】
図１２は内側の係合作動レバー５６を示す正面図である。この内側の係合作動レバー５６は、用語のとおり、内側の切換え手段５１と内側の係合アーム４１にそれぞれ係合する。ところで、特に図示しないが外側の係合作動レバー５６（便宜上、同一の符号を付す。）がケース身３ａの内壁面側にある。外側の係合作動レバー５６は、その形状が内側のそれと同一か否かを問わず、内側の係合作動レバー５６と同様な作用や機能を有する。したがって、外側の係合作動レバー５６も、外側の切換え手段５２の後端部と外側の係合アーム４２の挟み状第１係合部４６にそれぞれ係合する。
【００３７】
図１２及び図１３を参照に内側の係合作動レバー５６の構成を説明する。ここでは、同一の作用を有する外側の係合作動レバーの説明を割愛する。内側の係合作動レバー５６は、例えば左手の親指と人差し指を広げた場合のように、全体として「Ｃ字型形状」をしている。５６ａは下端部、５６ｂは上端部、５６ｃは上端部と下端部に連設する板状連設部である。
【００３８】
しかして、前記下端部５６ａには、図１３で示すように内側の係合アーム４１の挟み状第１係合部４６，４６に係合する突起５７が設けられている。一方、板状連設部５６ｃの上部の一部には内側の切換え手段５１の後端部５１ｃに係合可能な係合突片５８が設けられている。この係合突片５８は前記上部の一部を内側に折り曲けることにより形成されている。さらに、幅広上端部５６ｂには施錠片５の長杆部５ｃの下方に位置するようにケース身３ａに固定された固定軸５９に嵌合する軸孔が形成されている。内側の係合作動レバー５６は前記固定軸５９を支点に回動する。
【００３９】
なお、外側の係合作動レバー５６も他の固定軸５９（便宜上、同一の符号を付す。）に軸支されている。また、必要に応じて内外の係合作動レバー５６を図示しないバネでそれぞれ一方向に付勢することができる。
【００４０】
６０は錠箱３内に移動可能に設けられた駆動源で、本実施例ではソレノイドが用いられている（図３参照）。ソレノイド６０は錠箱３の隅部に水平移動可能に配設され、作動杆の突出部６１には、中央部が錠箱３に軸支（軸６２）された棒状の駆動片６３が連結されている。駆動片６３の上端部６３ａは、内外係合アーム４１，４２の対向的な第２係合部４７内にそれぞれ係合可能に位置している。またソレノイド６０は、その上壁にオス係合部としての突起片６４を有している。
【００４１】
６５は枢軸１８の軸支されたレバー状の作動モード切換え手段である。この作動モード切換え手段６５は、内外の切換え手段と一緒に併設状態に枢軸１８に設けられている。そして、形態的には切換え手段の形状と多少異なるが、機能的には同様の部分が幾つかある。
【００４２】
図１４は作動モード切換え手段６５を示す正面図である。６５ａは軸孔を有する胴体部、６５ｂは胴体部から裏板１１の開口１１ａに向かって延伸する頭部、６５ｃは尾部である。
【００４３】
しかして、本実施例では、前記頭部６５ｂには、切換え手段５１，５２と同様に「クチバシ状」の小さな水平溝６６が形成され、該水平溝６６には、同じく小さなドライバー（工具）の先端部が係合可能である。また前記尾部部６５ｃには、上方に多少の間隙６７を有して延びる細幅の変位部６５ｄが連設している。そして、該変位部６５ｄの先端部には、同じく第１案内板１３のクリック感用突起１３ｄと摺接状態に係合する山形状の係合爪（説明の便宜上、切換え手段と同一の用語を用いる。）６８が形成されている。
また胴体部６５ａの下方には二脚状のメス係合突起６９が設けられ、該メス係合突起６９には前述したソレノドの突起片６４が係合する。
【００４４】
なお、作動モード切換え手段６５を操作すると、ソレノイド６０の配設位置が水平移動し、これにより電気錠の作動モードを非通電時施錠か、それとも通電時施錠かに切換えることができる。
【００４５】
上記構成に於いて、（１）電気錠の作動モードの切換え（非通電時施錠型か、それとも通電時施錠型かに切換えること）と、（２）電気錠の内外の操作部材態様（例えばレバーハンドルの回動操作を自由にするか、それとも固定的にロックすること）の切換えとをそれぞれ説明する。以下、概略的な図面を参照に説明する。
【００４６】
まず図１５は非通電時施錠型、かつ、内外の操作部材をロック態様にした場合の電気錠１である。この電気錠１は、ソレノイド６０に電気が流れていない時（非通電状態の時）に作動杆６１が伸張し、一方、通電時に作動杆６１が収縮する。枢軸１８を基準にすると、作動モード切換え手段６５の頭部６５ｂはやや上向である（左図）。また、内側の切換え手段５１の先端部５１ｂもやや上向きである。
【００４７】
図１５を参照にして電気錠１の作動状態を簡単に説明する。まず非通電時に於いて、ソレノイド６０の作動杆６１は伸張している。この時駆動片６３は略垂直状態に起立し、その上端部６３ａは内外係合アーム４１，４２の第２係合部４７内に位置している。
また内外係合アーム４１，４２の第１係合部４６は内外の駆動カム２０，２１に接近しているため、内外の操作部材用ロック手段３５，３６は、内外の駆動カム２０，２１の係合切欠部２８にそれぞれ入り込んでいる。この時内外の係合アーム４１，４２は、非通電時の時と全く変わらない。つまり、図３で示すように内外の操作部材用ロック手段３５，３６は、内外の駆動カム２０，２１の係合切欠部２８にそれぞれ入り込んでいる。
【００４８】
それ故に、電気錠１が非通電状態の時は、何らかのロック解消手段、例えばサムターン９、サムターンに連動する部材等を介して内側の操作部材用ロック手段３５のロックを解消させない限り、内側操作部材７を回すことができない。この点外側操作部材も同様であり、シリンダーを回さない限りロックされている。
【００４９】
これに対し、電気錠１の通電時（下図）は、上記とは逆であり、作動杆６１は矢印で示すように収縮する。この時駆動片６３は軸６２を支点に時計方向へ回転して傾倒状態となる。その結果、上端部６３ａは内外係合アーム４１，４２の軸受け部４５に近づく。
そうすると、内外係合アーム４１，４２は上端部６３ａを介して互いに逆方向に回転するため、湾曲状第２係合部４７並びに第１係合部４６の小突起４８は互いに離れる方向へと移動する。そのため内外の操作部材用ロック手段３５，３６は内外の駆動カム２０，２１の係合切欠部２８から離脱する。したがって、内外の操作部材７，６の阻止（ロック）の状態が同時に解消される。
【００５０】
図１６は、ソレノイドの位置を右側に多少移動させることにより、図１５の「非通電時施錠型の電気錠１」を「通電時施錠型の電気錠１」へと換えた、すなわち、作動モードを切換えた場合の説明図である。図１７は作動モードを切換えた場合の模式的説明図である。この場合内外の切換え手段５１，５２はそのままの状態なので、内外操作部材のロック態様は、図１５と同様である。単に電気錠の作動モードを変えたに過ぎない。
【００５１】
ところで、作動モードを変える場合には、錠箱３のフロント板４を取り外し、かつ裏板１１の開口１１ａから図示しないドイラバーを作動モード切換え手段６５の水平溝６６に差し込んで切換える。そうすると、ソレノイド６０は、所定位置までスライドする。なお、作動態様は重複するので割愛する。
【００５２】
図１８及び図１９は、電気錠のモード態様が、「非通電時施錠型の電気錠１」又は「通電時施錠型の電気錠１」の場合に於いて、内側の切換え手段５１のみを切換えた時の各説明である。非通電時施錠型であれ、又は通電時施錠型であれ、前述したように錠箱３のフロント板４を取り外し、かつ、裏板１１の開口１１ａから図示しないドイラバーを利用して内側の切換え手段５１の先端部５１ｂを下方へと切換えると、切換え手段５１は枢軸１８を基準にして時計方向へと回転する。
【００５３】
したがって、切換え手段５１の後端部５１ｃは上方へ移行する。この時切換え手段５１の細幅の先端部にある係合爪５５は、クリック感用突起１３ｄを超える。また内側の係合作動レバー５６は、その係合突片５８を介して切換え手段５１の後端部５１ｃに持ち上げられるので、該係合作動レバー５６は、固定軸５９を支点に時計方向へ所定量回転する。
そうすると、内側係合アーム４１は中央軸４３を支点に時計方向へと所定位置まで回転する。その結果、内側の操作部材用ロック手段３５は、内側係合アーム４１の第１係合腕４６側の小突起４８を介して内側の駆動カム２０の係合切欠部２８から離脱する。したがって、内側の操作部材７の阻止（ロック）の状態が解消される。この場合外側操作部材６は相変わらず外側の操作部材用ロック手段３６によりロックされている。
【００５４】

The outer engagement operation lever 56 is also pivotally supported by another fixed shaft 59 (for the sake of convenience, the same reference numeral is assigned). Further, if necessary, the inner and outer engagement operating levers 56 can be urged in one direction by a spring (not shown).
[0040]
A drive source 60 is movably provided in the lock box 3, and a solenoid is used in this embodiment (see FIG. 3). The solenoid 60 is disposed at the corner of the lock box 3 so as to be horizontally movable, and a rod-like drive piece 63 whose central part is pivotally supported (shaft 62) on the lock box 3 is connected to the protrusion 61 of the operating rod. ing. The upper end portion 63a of the drive piece 63 is positioned so as to be engageable with the opposing second engagement portion 47 of the inner and outer engagement arms 41 and 42, respectively. Moreover, the solenoid 60 has the protrusion piece 64 as a male engaging part in the upper wall.
[0041]
Reference numeral 65 denotes a lever-like operation mode switching means supported by the pivot 18. The operation mode switching means 65 is provided on the pivot 18 in a side-by-side state together with the internal and external switching means. There are some functionally similar parts, although the form is slightly different from the shape of the switching means.
[0042]
FIG. 14 is a front view showing the operation mode switching means 65. 65a is a body portion having an axial hole, 65b is a head portion extending from the body portion toward the opening 11a of the back plate 11, and 65c is a tail portion.
[0043]
In the present embodiment, the head 65b is formed with a small horizontal groove 66 having a “beaky” shape, similar to the switching means 51 and 52, and the horizontal groove 66 is also provided with a small screwdriver (tool). The tip can be engaged. In addition, a narrow displacement portion 65d extending with a slight gap 67 is connected to the tail portion 65c. Further, at the tip of the displacement portion 65d, a mountain-shaped engagement claw that engages with the click feeling projection 13d of the first guide plate 13 in the same sliding state (for convenience of explanation, the same term as the switching means is used. Used.) 68 is formed.
A bipod-shaped female engaging projection 69 is provided below the body portion 65 a, and the above-described Sorenod protruding piece 64 is engaged with the female engaging projection 69.
[0044]
When the operation mode switching means 65 is operated, the position of the solenoid 60 is moved horizontally, whereby the operation mode of the electric lock can be switched between locking when not energized or locking when energized.
[0045]
In the above configuration, (1) switching of the operation mode of the electric lock (switching between the non-energized locking type and the energized locking type), and (2) the operation member mode (for example, lever) inside and outside the electric lock The switching of the operation of turning the handle freely or fixing the handle in a fixed manner will be described. Hereinafter, description will be made with reference to the schematic drawings.
[0046]
First, FIG. 15 shows the electric lock 1 when the non-energized locking type is used and the inner and outer operation members are in a locked state. In the electric lock 1, the operating rod 61 expands when electricity is not flowing through the solenoid 60 (in a non-energized state), while the operating rod 61 contracts when energized. With reference to the pivot 18, the head 65b of the operation mode switching means 65 is slightly upward (left figure). The tip 51b of the inner switching means 51 is also slightly upward.
[0047]
The operating state of the electric lock 1 will be briefly described with reference to FIG. First, at the time of de-energization, the operating rod 61 of the solenoid 60 is extended. At this time, the drive piece 63 stands up in a substantially vertical state, and its upper end 63 a is located in the second engagement portion 47 of the inner and outer engagement arms 41, 42.
Since the first engaging portions 46 of the inner and outer engaging arms 41 and 42 are close to the inner and outer driving cams 20 and 21, the inner and outer operating member locking means 35 and 36 are connected to the inner and outer driving cams 20 and 21, respectively. Respectively entering the engagement notch 28. At this time, the inner and outer engagement arms 41 and 42 are not different from those at the time of non-energization. That is, as shown in FIG. 3, the inner and outer operation member locking means 35 and 36 are respectively inserted into the engagement notches 28 of the inner and outer drive cams 20 and 21.
[0048]
Therefore, when the electric lock 1 is in a non-energized state, the inner operation member is not unlocked unless the lock of the inner operation member lock means 35 is released via some lock release means, for example, the thumb turn 9 or a member interlocked with the thumb turn. Cannot turn 7. This outside operation member is the same, and is locked unless the cylinder is rotated.
[0049]
On the other hand, when the electric lock 1 is energized (the following figure), the above is opposite, and the operating rod 61 contracts as shown by the arrow. At this time, the driving piece 63 is tilted by rotating clockwise around the shaft 62 as a fulcrum. As a result, the upper end portion 63 a approaches the bearing portion 45 of the inner and outer engagement arms 41 and 42.
Then, the inner and outer engagement arms 41 and 42 rotate in opposite directions via the upper end portion 63a, so that the curved second engagement portion 47 and the small protrusion 48 of the first engagement portion 46 move away from each other. To do. Therefore, the inner and outer operation member locking means 35 and 36 are disengaged from the engagement notches 28 of the inner and outer drive cams 20 and 21. Therefore, the blocking (locking) state of the inner and outer operation members 7 and 6 is canceled at the same time.
[0050]
FIG. 16 shows that the position of the solenoid is moved slightly to the right to change the “non-energized lock type electric lock 1” to the “energized lock type electric lock 1” in FIG. It is explanatory drawing at the time of switching. FIG. 17 is a schematic explanatory diagram when the operation mode is switched. In this case, since the inside and outside switching means 51 and 52 are left as they are, the lock mode of the inside and outside operation members is the same as that in FIG. It merely changed the operating mode of the electric lock.
[0051]
By the way, when changing the operation mode, the front plate 4 of the lock box 3 is removed, and a driver bar (not shown) is inserted into the horizontal groove 66 of the operation mode switching means 65 from the opening 11a of the back plate 11 and switched. Then, the solenoid 60 slides to a predetermined position. In addition, since an operation mode overlaps, it omits.
[0052]
18 and 19 show that only the inner switching means 51 is switched when the mode mode of the electric lock is “non-energized locking type electric lock 1” or “energized locking type electric lock 1”. It is each explanation at the time. Regardless of the non-energized locking type or the energized locking type, the front plate 4 of the lock box 3 is removed as described above, and the inner switching means is utilized from the opening 11a of the back plate 11 using a screwdriver bar (not shown). When the tip 51b of 51 is switched downward, the switching means 51 rotates clockwise with the pivot 18 as a reference.
[0053]
Therefore, the rear end portion 51c of the switching means 51 moves upward. At this time, the engaging claw 55 at the narrow end of the switching means 51 exceeds the click feeling projection 13d. Further, since the inner engagement operating lever 56 is lifted to the rear end portion 51c of the switching means 51 through the engagement protrusion 58, the engagement operating lever 56 is positioned clockwise with the fixed shaft 59 as a fulcrum. Rotate quantitatively.
Then, the inner engagement arm 41 rotates clockwise to a predetermined position with the central shaft 43 as a fulcrum. As a result, the inner operating member locking means 35 is disengaged from the engagement notch 28 of the inner drive cam 20 via the small protrusion 48 on the first engagement arm 46 side of the inner engagement arm 41. Therefore, the state of blocking (locking) the inner operation member 7 is eliminated. In this case, the outer operating member 6 is still locked by the outer operating member locking means 36.
[0054]
20 and 21 show that only the outer switching means 52 is switched when the mode mode of the electric lock is "non-energized locking type electric lock 1" or "energized locking type electric lock 1". It is explanation when. As described above, whether it is a non-energized locking type or an energized locking type, the front plate 4 of the lock box 3 is removed, and an outside switching means is used from the opening 11a of the back plate 11 using a driver bar (not shown). The tip of 52 is switched downward.
[0055]
At the time of this switching, the sliding contact relationship between the engaging claw at the narrow tip of the outer switching means and the click feeling projection, the rear end of the outer switching means and the outer engagement operating lever When the outer engagement operating lever rotates counterclockwise around another fixed shaft, the outer engagement arm rotates clockwise by a predetermined amount around the central axis. As a result, the operation mode such as the relationship in which the outer operation member lock means is disengaged from the engagement notch portion of the outer drive cam through the small protrusion on the first engagement arm side of the outer engagement arm is the inner switching means. This is the same as the case where is switched downward.
[0056]
Therefore, the blocking (locking) state of the outer operation member 6 is eliminated. In this case, the inner operation member 7 is still locked by the inner and outer operation member locking means 35, which is completely opposite to the case of FIG. Thus, by switching the switching means of the inner and outer operation member modes downward or upward, the inner and outer operation members 6 and 7 can be immediately turned.
[0057]
【Example】
In the embodiment of the present invention, a groove for engaging the tip of the tool (tribar) is provided at the tip of the inner switching means 51, the outer switching means 52, etc., but this is not necessarily a specific requirement of the invention. . Moreover, you may make the square cylindrical guide member which guides a dead bolt with a hard metal.
[0058]
【The invention's effect】
As is clear from the above description, the present invention has the following actions and effects.
(1) It is possible to provide an electric lock switching device capable of freely switching between an operation mode and an internal / external operation member with one electric lock.
(2) By simply removing the front plate from the lock box, the operation mode of the electric lock and / or the mode of the internal and external operation members can be easily switched.
(3) Each actuating member can be rationally combined to make switching appropriate.
(4) When the lever-like switching means is switched, a “click feeling” can sometimes be obtained.
(5) Even if the distance between the left and right shafts that pivot each member is reduced in order to make the lock box compact, for example, the switching force of the inner switching means is transmitted to the inner drive cam for the inner operation member.
(6) The deadbolt can be smoothly guided.
