Description

【０００１】
【発明の属する技術分野】
本発明は、地震時に適合するドア用錠受け金具に関する。
【０００２】
【従来の技術】
従来技術の一例としては、特開平１１−６２３３７号（特許第３０３７９１３号）に記載の一例がある。この実施例のドア用錠受の構成は次の通りである。
【０００３】
「ドア枠に設けた取付け孔（受入れ口）に固定する固定部材と、ドア側のカンヌキを係脱させる係止孔が形成され、かつ、固定部材に挿嵌されて該固定部材を介して取付け孔に嵌め込み状態に支持させる筒形部材と、筒形部材に固定され、かつ、取付け孔と固定部材及び筒形部材の全体を覆うカバーとを備え、筒形部材は、ドア閉鎖時にドアと平行方向に付与される面内外力の発生方向に所定間隔をあけて固定部材に挿嵌され、この間隔の範囲で面内外力の発生方向にスライド可能とされ、また、面内外力と直交方向の面外外力が発生したときは、固定部材に対しスライド不能とした状態で、ドア枠の取付け孔に嵌め込み状態に保持させて面外外力と対抗させるようにしており、カバーは、所定以上の面内外力が発生したとき変形して、その発生方向への筒形部材の固定部材に対するスライドを許し、通常時には筒形部材の固定部材に対するスライドを阻止するようにドア枠に保持されているドア用錠受」。
【０００４】
ところで、該ドア用錠受は、普通一般に扉を左右何れから開くかによって、ドア枠の左縦枠か、それとも右縦枠かのいずれかに取付けられるが、上記実施例は、左右勝手自由に取付けることができる旨の構造が具体的に示されていないので改良すべき問題点を含んでいる。また、該ドア用錠受は、ドア枠に設けた取付け孔（受入れ口）と丁度嵌合する筒形部材にケース状の固定部材を貫通状態に挿入嵌合し、筒形部材の上下の開口端から突出した前記固定部材の取付け耳部（取付け片）をドア枠の正面壁に固着するものであるから、地震発生時、筒形部材はカバーの上下斜辺部分の変形に伴い水平方向に後退動可能なものの、上下方向に移動できないという問題点を有している。であるから、地震の揺れ方向如何により、筒形部材が著しく変形する可能性がある。それ故に、ドアの開閉がスムースにできなくなる可能性がある。
【０００５】
【発明が解決しようとする課題】
本発明は以上のような従来の要望点に鑑み、第１の目的は、錠前の施錠片の位置等を変更しないで、少なくとも可動コアをそのままドア枠の左縦枠、又は右縦枠のいずれにでも自由に取付けることができるドア用錠受け金具を提供することである。第２の目的は、第１の目的を前提として地震発生時、地震の揺れ方向如何に拘わらず、施錠片と関係があるストライク及び可動コアが、トロヨケ内の後方空隙部ないし上下の空隙部へと多方向へ後退動することができることである。
【０００６】
これによりドアの開閉がスムースにできなくなる危険性を極力回避することができる。第３の目的は、切欠部を有する可動コアの上下端部が容易に変形や破壊しないことである。これにより、保持ピンが外れ、可動コアが落下するのを未然に防ぐことができる。その他各部材を合理的に組み合わせることができることである。
【０００７】
【課題を解決するための手段】
本発明のドア用錠受け金具は、ドア枠１に嵌合状態に固定されるトロヨケ２と、このトロヨケの奥の内壁面並びに上下の対向内壁との間にそれぞれ空隙部４５、４６を設定してその正面開口１６から該トロヨケ内に遊嵌合状態に嵌め込まれる枠状可動コア３と、トロヨケ２及び可動コア３の正面側をカバーするように可動コア３を介して前記ドア枠１の正面壁１０ａに当接状態に取付けられるカバー状ストライク４とから成り、前記トロヨケ２の左右の側壁１５ｃ，１５ｃには左右一対の保持ピン逃し用切欠部２０，２０が形成され、前記保持ピン２１は切欠部２０，２０に係合した状態で該切欠部２０，２０並びに可動コア３の左右の側壁３ｃ，３ｃに形成した挿通孔２８を貫通し、地震発生時、前記ストライク並びに可動コアは、ストライクの傾斜状上下端部の変形に伴い前記空隙部４５、４６の方向Ｘ・Ｙへと移動し、さらに、前記可動コア３の左右の側壁３ｃ，３ｃの中央部には、所要長さの垂直案内係合長孔３２を形成し、これら左右一対の垂直案内係合長孔には、施錠片６を受ける受け棒部材３３を架設したことを特徴とする。
【０００８】
上記の構成に於いて、自重で落下する施錠片用受け棒部材３３は、垂直案内係合長孔３２の下方に位置する縁部３２ａに支持されるスライド係合ピン３３ａと、このスライド係合ピンに貫通状態に挿嵌された回転筒３３ｂとから成ることを特徴とする。
【０００９】
また本発明のドア用錠受け金具は、ドア枠１に嵌合状態に固定されるトロヨケ２Ａと、このトロヨケの奥の内壁面並びに上下の対向内壁との間にそれぞれ空隙部４５、４６を設定してその正面開口１６から該トロヨケ内に遊嵌合状態に嵌め込まれる枠状可動コア３Ａと、トロヨケ２Ａ及び可動コア３Ａの正面側をカバーするように可動コア３Ａを介して前記ドア枠１の正面壁１０ａに当接状態に取付けられるカバー状ストライク４Ａとから成り、前記トロヨケ２Ａの左右の側壁１５ｃ，１５ｃには、左右一対の保持ピン用挿通孔２８Ａ，２８Ａが形成され、前記保持ピン２１は可動コア３Ａの左右の側壁３ｃ，３ｃに形成した保持ピン逃し用切欠部２０Ａ，２０Ａに係合した状態で貫通し、地震発生時、前記ストライク並びに可動コアは、ストライクの傾斜状上下端部の変形に伴い前記空隙部４５、４６の方向Ｘ・Ｙへと移動し、さらに、前記可動コア３の左右の側壁３ｃ，３ｃの中央部には、所要長さの垂直案内係合長孔３２を形成し、これら左右一対の垂直案内係合長孔には、施錠片６を受ける受け棒部材３３を架設したことを特徴とする。
【００１０】
また上記構成に於いて、可動コア３Ｂの上下の端部内に、それぞれ枠状の補強部材５０を固定的に添着したことを特徴とする。
【００１１】
【発明の実施の形態】
まず、図１及び図２に於いて、本発明の実施の環境部材を説明する。１はドア枠、２はドア枠に嵌合状態に固定されるトロヨケ、３はトロヨケ内に、少なくともトロヨケの奥の内壁面並びに上下の対向内壁との間にそれぞれ空隙部を設定して遊嵌合状態に嵌め込まれる枠状可動コア、４はトロヨケ２及び可動コア３の正面側を全体又は部分的にカバーするように可動コア３を介し、例えばドア枠１の左側縦枠の方に選択的に取付け用とする場合には、左側縦枠の角筒部の正面壁に当接状態に取付けられるカバー状ストライク、５はドア枠１に対して開閉可能に設けられるドア、６はドア側に設けた錠前の第１施錠片（ここではデッドボルト）、７はデッドボルト６と並存的に設けられた錠前の第２の施錠片（ここでは鎌片）である。
【００１２】
なお、前記鎌片７は、防犯機能を高めるために設けられており、施錠時、図１で示すようにデッドボルト６と水平方向に重なった状態で可動コア３の正面壁２６の内壁面に対してその先端部が掛合可能な状態となっている。そして、本実施例の受け金具は、可動コアやストライクを逆様にする（１８０度回す）だけで、ドア枠１の左側縦枠又は右側縦枠の何れにでも選択的に取付けることができる構造である。
【００１３】
図１はドア枠１の左側縦枠の角筒部にトロヨケ２、枠状可動コア３、カバー状ストライク４をそれぞれ固定的に取付けた場合における通常の使用状態を示す。なお、本発明の特定要件に関係のない部分（例えばドア枠の他の部分、錠前のラッチなど）は省略してある。
【００１４】
次に図２乃至図８を参照にして本発明の第１実施例を説明する。図２はドア用錠受け具を構成する各部材の分解斜視図である。図２の左側から錠受け具の構成部材を順番に説明する。
【００１５】
まず簡略化したドア枠１から説明する。角筒部１０はドア５の垂直端面と対向する一部のみを示してある。１０ａは正面壁、１０ｂは背面壁、１０ｃ，１０ｃは左右の側壁、１１は前記正面壁１０ａに形成された縦長状の受入れ口（固定トロヨケと係合する係合長孔）、１２は受入れ口に連通するように左側の上下の部位にそれぞれ垂直線状に切欠されたストライク用切欠溝、１３はこれらの切欠溝１２，１２付近の正面壁１０ａに形成された上下のネジ孔である。
【００１６】
次にトロヨケ２について説明する。トロヨケ２の形状は普通一般のそれと同様である。すなわち、トロヨケ２の部分を区分けすると、図３で示すように、ドア枠１の受入れ口１１にスッポリトと入り込む正面開口１６の角形ケース部１５と、この角形ケース部１５の正面開口１６側の上下端部にそれぞれ一体形成された突片状の取付け片１７，１７とから成り、前記取付け片１７，１７には、ドア枠１のネジ孔１３，１３と符合する貫通孔１８，１８が形成されている。
【００１７】
しかして、本実施例では、前記角形ケース部１５の左右の側壁１５ｃ，１５ｃの上下の部位には、左右一対の保持ピン逃し用切欠部２０，２０がそれぞれ計４個形成されている。これらの切欠部２０は、図１又は図２で示すように、それぞれ上下一対の可動コア用保持ピン２１，２１と関係する。
【００１８】
すなわち、各保持ピン２１は左右一対の逃し用切欠部２０，２０をそれぞれ貫通する。切欠部２０は、通常の使用状態では、一つの保持ピン２１の外周面と一部係合するやや半円弧状の小係合溝２０ａと、該切欠部２０の中央部に相当する基準縁部としての小係合溝２０ａを基準にして角形ケース部１５の背面壁１５ｂ方向に拡大して幅広（例えば矩形状、垂直長孔状など）に広がる保持ピン逃し部２０ｂとを有している。
また前記左右の側壁１５ｃ，１５ｃの上下部位寄りの部位には、小さな被係合部（例えば係合小孔、内壁面に形成された小さな溝など）２２，２２が形成されている。
【００１９】
次に可動コア３について説明する。可動コア３は、図１、図４で示すように、前後に開口を有する箱型形状に形成されている。すなわち、３ａ，３ａは上下の正面壁で、本実施例では、施錠時、鎌片７の先端部はいずれか一方の正面壁３ａの内壁面に対して掛合可能な状態となっている（鎌片７は可動コアに対しては係合している）。
【００２０】
３ｃ，３ｃは左右の側壁、２５は前記正面壁３ａ，３ａの間に形成された縦長の前方開口、２６は正面壁３ａ，３ａにそれぞれ形成された上下の縦長状凹所、２７はこれらの凹所２６，２６にそれぞれ形成された複数個のネジ孔、２８は前記左右の側壁３ｃ，３ｃの上下にそれぞれ形成された保持ピン用挿通孔、３０は左右の側壁３ｃ，３ｃの上下部位寄りの部位にそれぞれ形成され、かつ、前述したトロヨケ２の小さな被係合部２２，２２にそれぞれ係脱する小さな係合部（例えば小突起）、３１は後方開口、３２は左右の側壁３ｃ，３ｃの中央部にそれぞれ形成された所要長さの垂直案内係合長孔、３３は左右一対の垂直案内係合長孔３２，３２に架設された施錠片用受け棒部材である。
【００２１】
しかして、施錠片用受け棒部材３３は、図１で示すように、可動コア３を縦状態にすると自重で落下する。したがって、受け棒部材３３は、左右一対の垂直案内係合長孔３２，３２の下方に位置する弧状縁部３２ａ，３２ａ（可動コア３を１８０度回すと、上方の弧状縁部が下方になる）に支持されるスライド係合ピン３３ａと、このスライド係合ピンに貫通状態に挿嵌された回転筒３３ｂとから成る。
【００２２】
ところで、図１で示すように、可動コア３は係合部３０や上下の保持ピン２１，２１を介してトロヨケ２に遊嵌合状態に保持される。可動コア３がトロヨケ２に遊嵌合した時、可動コア３の小突起状の係合部３０，３０は、トロヨケ２の小さな被係合部２２，２２にそれぞれ係合する。したがって、トロヨケ２と可動コア３は、仮ではあるが一体的になる。
【００２３】
また、可動コア３に入り込んだ施錠片６の下面と受け棒部材３３との間には、多少のクリアランス（たとえば７ｍｍ程度）が設定されているが、地震時にドア枠の変形によって傾倒した施錠片６が直接当るのは前記回転筒３３ｂである。それ故に、可動コア３は、施錠片６を受ける受け棒部材３３を介して少なくともトロヨケ２側（下方空隙部４６及び奥の内壁面側の後方空隙部４５）に移動する（図８参照）。なお、また本実施例では鎌片７も設けられているので、施錠片６と同時に鎌片７が後退しながら上昇した場合には、可動コア３の前方開口２５の上縁部が、両方の施錠片６，７からその衝撃力を受ける。
【００２４】
次に図４を参照にしてカバー状のストライク４について説明する。３５はカバー部本体、３６はカバー部本体に上方と下方にそれぞれ連設する変形可能な傾斜状上下端部、３７はカバー部本体の右側端部から該カバー部本体に直交するように設けられた進入係合側壁、３８は可動コア３の前方開口２５と同一形状の正面開口、３９はカバー部本体の上下部に形成され、かつ、可動コア３の計２個のネジ孔２７，２７とそれぞれ符合するストライク固着具４０用の挿通孔である。
【００２５】
なお、ストライク４は、前記進入係合側壁３７に対向する他方側の側壁を有しない。またドア枠１の切欠溝１２に係合する進入係合側壁３７の上下の突片状端部３７ａ，３７ａと傾斜状上下端部３６，３６とは互いに切れている。
【００２６】
したがって、ストライク４のトロヨケ固着具４１，４１をカバーする前記傾斜状上下端部３６，３６は、例えばストライク４を戸枠側に押し付ける略水平方向Ｘ、又はストライク４をドア５の端面側に押し付ける逆方向Ｘの衝撃力が作用すると変形可能である。
【００２７】
次に各部材の組み合わせについて簡単に説明する。まずトロヨケ２と可動コア３とを一体的に組み合わせる。この時受け棒部材３３のスライド係合ピン３３ａの両端部を左右の垂直案内係合長孔３２，３２にそれぞれ係合させる。これにより受け棒部材３３の回転筒３３ｂは、可動コア３の左右の側壁内に回転自在に位置する。また、トロヨケ２の被係合部２２，２２に可動コア３の係合部３０，３０を係合させる。また上下の保持ピン２１，２１をトロヨケ２の上下の切欠部２０，２０と可動コア３の上下の挿通孔２８，２８にそれぞれ差し込む。
【００２８】
次にトロヨケ２のケース部１５を、例えば図２で示すように、ドア枠１の左縦枠の受入れ口１１に嵌め込み、上下の取付け片１７，１７をドア枠１の正面壁１０ａに面接触させる。そして、トロヨケ固着具４１，４１を可動コアの貫通孔１８，１８に合わせてドア枠のネジ孔１３，１３に螺締する。これによりトロヨケ２はドア枠１に固着される。
【００２９】
ところで、受け棒部材３３は、前述したように可動コア３を縦状態にすると、左右の垂直案内係合長孔３２，３２を介して自重で下方に落下する。したがって、本実施例の受け棒部材３３は、錠受け具を構成する可動コア並びにストライクをそれぞれ１８０度回転（上下に反転）しても、施錠片６の下面と当接可能であるから、戸枠１に対しては左右勝手自由に使用することができる。
【００３０】
そこで、次にストライク４をトロヨケ２の上下の取付け片１７，１７を覆うようにする。しかる後にストライク固着具４０，４０を挿通孔３９，３９にそれぞれ合わせて可動コア３のネジ孔２７，２７に螺締する。螺締すると、上下の保持ピン２１，２１はトロヨケの小係合溝２０ａに確実に係合するから、図１，図５に示すように、各部材２，３，４は一体的になる。なお、施錠片６の上面とストライク４の正面開口２８の上縁部との間には多少のリアランスがある。
【００３１】
図６及び図７は、ドア枠１が変形するような地震発生時における可動コア３の移動方向の一例を示す。前述したように、地震発生時、例えば施錠片６がドア枠１の変形によって施錠片６の下面と受け棒部材３３とが互いに衝突し合った場合には、可動コア３がその回転筒３３ｂを介して施錠片６から強い衝撃力を受ける。なお、この時回転筒３３ｂは傾倒する施錠片６によって回転する。それ故に、施錠片６が回転筒３３ｂに圧接していても、ドアは開き易くなる。
【００３２】
したがって、今仮に、図１の使用状態に於いて、ストライク４のカバー部本体３５の壁面に対して交差する方向Ｘの面外外力が発生すると同時に、カバー部本体３５の壁面に対して平行する方向Ｙの外力が発生した場合には、ドア枠１とドア５との間でストライク４が水平〜垂直方向へと衝撃的に押圧されることになるから、その上下端部３６，３６は外拡変位してドア枠１の正面壁１０ａをトロヨケ方向Ｘ並びに上下方向Ｙへとスライドする。この時可動コア３の小係合突起３０，３０は変形し、或いは破壊してトロヨケ２の小孔２２から外れる。
【００３３】
しかし、保持ピン２１を介してトロヨケ４と可動コア３は一体であるから、トロヨケ４と可動コア３は、トロヨケ１内の後方空隙部４５及び上下の空隙部４６へと多方向へ後退上下動する。したがって、可動コア用保持ピン２１，２１は、可動コア３の後退上下動に対応してトロヨケ２の切欠部２０の小係合溝２０ａから幅広の保持ピン逃し部２０ｂへと移行する。
【００３４】
【実施例】
第１実施例に於いて、トロヨケ２の左右の側壁１５ｃ，１５ｃの上下の部位には、左右一対の保持ピン逃し用切欠部２０，２０がそれぞれ計４個形成されているが、ドア側の錠前の構造如何によってはその数を増やし又は減じても良い（例えば中央部にも左右一対保持ピン逃し用切欠部２０，２０を形成するなど）。また可動コアの左右の側壁に被係合部２２を形成し、一方、トロヨケの左右の側壁に前記被係合部２２に仮止め係合する係合部３０を設けることも均等事項である。
【００３５】
次に図９乃至図１１に示す第２実施例について説明する。なお、第２実施例の説明にあたって、第１実施例と同一の部分には、同一又は同様の符合を付して重複する説明を省略する。
【００３６】
第２実施例において、前記実施例と主に異なる点は、本発明の要部（保持ピン用切欠部と挿通孔の形成対象）を設計変更したことである。すなわち、図１０で示すようにトロヨケ２Ａの左右の側壁１５ｃ，１５ｃの方に保持ピン２１，２１用の挿通孔２８Ａ，２８Ａを上下にそれぞれ形成し、一方、可動コア３Ａの左右の側壁３ｃ，３ｃに、保持ピン逃がし用切欠部２０Ａ，２０Ａを上下にそれぞれ形成したことである。
【００３７】
この実施例の上下の保持ピン２１，２１と上下の切欠部２０Ａ，２０Ａとの係合関係は、図９に示す通りである。この図９と第１実施例の図１とを比較すると、切欠部２０Ａ，２０Ａの向きが逆になっており、ストライク固着具４０，４０を螺締した時は、上下の保持ピン２１，２１は、トロヨケ２Ａ内の後方空隙部４５側に位置する小係合溝２０ａ，２０ａにそれぞれ係合する。このように設計変更しても第１実施例と同一の作用・効果がある。
【００３８】
図１２乃至図１５に示す第３実施例に於いて、前記第１実施例と主に異なる点は、可動コア３Ｂの上下の端部内に、それぞれ枠状の補強部材５０を固定的に添着したことである。また、可動コア３Ｂの上下の端面が開口５１していると共に、可動コア３Ｂそのものを強靭にするために、左右の側壁３ｃ，３ｃの後方端面５２を内側に折り曲げている。
【００３９】
この第３実施例の可動コア３Ｂも第２実施例の可動コア３Ａと同様に左右の側壁の上下端部に幅広の切欠部２０Ｂ，２０Ｂが形成されている。したがって、上下の保持ピン２１，２１が係合する挿通孔２８Ｂ，２８Ｂも第２実施例のトロヨケと同様にトロヨケ２Ｂの方に形成されている。
【００４０】
内端面コ字型状補強部材５０の構成について説明する。補強部材５０は、図１２で示すように、可動コア３Ｂの上下の端部内に上下対称に組み込まれている。５５はストライク４Ｂのカバー本体部３５Ｂの端部内壁面に当接する突片部５６を有する取付け板部で、この取付け板部５５には、可動コア３Ｂと補強部材５０との結合を図る第１固着具５７用の第１ネジ孔５８と、可動コア３Ｂをストライク４Ｂに固定するために、補強部材５０とストライク４Ｂと結合を図る第２固着具５９用の第２ネジ孔６０がそれぞれ形成されている。
【００４１】
６１，６１は取付け板部５５に対して交差方向に折り曲げられ、可動コア３Ｂの左右の側壁３ｃ，３ｃの端部と面接触状態に対向する左右対向壁である。これらの対向壁６１，６１には、可動コア３Ｂの幅広の切欠部２０Ｂ，２０Ｂと符合する同一形状の保持ピン用の補強切欠部６２，６２が形成されている。
【００４２】
なお、本実施例では、ストライク４Ｂの挿通孔３９Ｂは補強部材５０の第２ネジ孔６０と符合する。また可動コア３Ｂの上下の正面壁３ａ，３ａの下端部の中央部は、第２固着具５９が通過することができるように弧状切欠部６５，６５が形成されている。
【００４３】
上記構成に於いて、まず、補強部材５０を可動コア３Ｂの上下開口５１，５１を介して可動コア３Ｂの上下端部内にそれぞれ差し込む。そして、第１固着具５７を可動コア３Ｂのネジ孔２７に通して補強部材５０の第１ネジ孔５８に螺締する。これにより可動コア３Ｂと補強部材５０は一体的に結合する。この時、補強部材５０の突片部５６は、カバー本体部３５Ｂの端部内壁面にピッタリと当接可能な状態となる。また補強部材５０の補強切欠部６２と可動コア３Ｂの切欠部２０Ｂは完全に連通状態となる。
【００４４】
次にストライク４Ｂの挿通孔３９Ｂに第２固着具５９を通して補強部材５０の第２ネジ孔６０に螺締する。これにより可動コア３Ｂとストライク４Ｂは一体的に結合する。
【００４５】
このように構成すると、切欠部２０Ｂを有する可動コア３Ｂの上下端部が容易に変形や破壊しない。したがって、保持ピン２１が外れて可動コア３Ｂが落下すること未然に防ぐことができる。
【００４６】
なお、この第３実施例の可動コア２Ｂは、ストライク４Ｂの挿通孔３９Ｂを通って螺合する補強部材５０を介してストライクに間接的に固着されているが、可動コアの正面壁の凹所２６に複数個のネジ孔を形成し、一方、ストライクに前記ネジ孔と対応する複数個の挿通孔を形成し、複数個の固着具を介してストライク４Ｂと可動コア２Ｂとを互いに直接的に一体化しても良い。また前記補強部材５０は、第２実施例に適用した例で説明したが、第１実施例に適用しても良い。
【００４７】
【発明の効果】
以上の説明から明らかなように、本発明にあっては、次に列挙するような効果がある。（１）錠前の施錠片の位置等を変更しないで、そのままドア枠の左縦枠、又は右縦枠のいずれにでも自由に取付けることができる。
（２）地震発生時、地震の揺れ方向如何に拘わらず、施錠片と関係があるストライク及び可動コアが、トロヨケ内の後方空隙部ないし上下の空隙部へと多方向へ後退動することができる。これによりドアの開閉がスムースにできなくなる危険性を極力回避することができる。
（３）補強部材を有する実施例の場合には、切欠部を有する可動コアの上下端部が容易に変形や破壊しないようにすることができる。これにより、保持ピンが外れ、可動コアが落下防止するのを未然に防ぐことができる。
（４）係合部と被係合部を有する実施例の場合には、可動コアをトロヨケに組み合わせる際に簡単に仮止めすることができる。
（５）その他各部材を合理的に組み合わせることができる。

BACKGROUND OF THE INVENTION
The present invention relates to a lock bracket for a door that is suitable for an earthquake.
[0002]
[Prior art]
As an example of the prior art, there is an example described in JP-A-11-62337 (Patent No. 3037913). The structure of the door lock of this embodiment is as follows.
[0003]
“A fixing member for fixing to a mounting hole (receiving port) provided in the door frame and a locking hole for engaging and disengaging the door-side cannula are formed, and is inserted into the fixing member and attached via the fixing member. A cylindrical member that is fitted in the hole and supported, and a cover that is fixed to the cylindrical member and covers the mounting hole, the fixing member, and the entire cylindrical member, and the cylindrical member is parallel to the door when the door is closed. Is inserted into the fixing member at a predetermined interval in the direction of generation of the in-plane external force applied in the direction, and is slidable in the direction of generation of the in-plane external force within the range of this interval, and is orthogonal to the in-plane external force When an out-of-plane external force is generated, the fixed member is made slidable and is held in the door frame mounting hole so as to be opposed to the out-of-plane external force. When internal / external force is generated, Allowing sliding relative to the stationary member of the tubular member to the raw direction, door lock receiving held in the door frame so as to prevent sliding with respect to the fixed member of the cylindrical member at the time of normal. "
[0004]
By the way, the door lock is generally attached to either the left vertical frame or the right vertical frame of the door frame depending on whether the door is opened from the left or right side. Since the structure that can be attached is not specifically shown, there is a problem to be improved. In addition, the door lock is formed by inserting and fitting a case-like fixing member in a penetrating manner into a cylindrical member that just fits into a mounting hole (accepting port) provided in the door frame. Since the mounting ears (mounting pieces) of the fixing member protruding from the end are fixed to the front wall of the door frame, the cylindrical member is retracted in the horizontal direction along with the deformation of the upper and lower oblique sides of the cover in the event of an earthquake. Although it can move, it has a problem that it cannot move up and down. Therefore, the cylindrical member may be significantly deformed depending on the direction of the earthquake. Therefore, there is a possibility that the door cannot be opened and closed smoothly.
[0005]

It is to provide a door lock bracket that can be freely attached to the door. The second purpose is that if the earthquake occurs assuming the first purpose, the strike and movable core related to the locking piece will move to the rear gap or the upper and lower gaps in the troyoke regardless of the direction of the earthquake. It is possible to move backward in multiple directions.
[0006]
As a result, it is possible to avoid the danger that the door can be opened and closed smoothly. The third purpose is that the upper and lower end portions of the movable core having the notch portions are not easily deformed or broken. Thereby, it is possible to prevent the holding pin from coming off and the movable core from dropping. In addition, each member can be rationally combined.

[0013]
FIG. 1 shows a normal use state when the troyoke 2, the frame-like movable core 3, and the cover-like strike 4 are fixedly attached to the rectangular tube portion of the left vertical frame of the door frame 1, respectively. Note that portions not related to the specific requirements of the present invention (for example, other portions of the door frame, latches of locks, etc.) are omitted.
[0014]
Next, a first embodiment of the present invention will be described with reference to FIGS. FIG. 2 is an exploded perspective view of each member constituting the door lock receiver. The components of the lock receiver will be described in order from the left side of FIG.
[0015]
First, the simplified door frame 1 will be described. Only a part of the rectangular tube portion 10 facing the vertical end surface of the door 5 is shown. 10a is a front wall, 10b is a back wall, 10c and 10c are left and right side walls, 11 is a vertically long receiving port (engagement long hole engaging with a fixed trowel) formed on the front wall 10a, and 12 is a receiving port. Strike notch grooves 13 that are notched in a vertical line at the upper and lower parts on the left side so as to communicate with the upper and lower parts are upper and lower screw holes formed in the front wall 10a in the vicinity of these notch grooves 12 and 12, respectively.
[0016]
Next, Troyoke 2 will be described. The shape of Troyoke 2 is generally the same as that of ordinary ones. That is, when the portion of the troyoke 2 is divided, as shown in FIG. 3, the rectangular case portion 15 of the front opening 16 that enters into the receiving port 11 of the door frame 1 and the upper and lower sides of the rectangular case portion 15 on the front opening 16 side. Each of the mounting pieces 17 and 17 is formed with through-holes 18 and 18 coinciding with the screw holes 13 and 13 of the door frame 1. ing.
[0017]
Thus, in this embodiment, a total of four left and right holding pin relief notches 20 and 20 are formed in the upper and lower portions of the left and right side walls 15c and 15c of the rectangular case portion 15, respectively. These notches 20 are related to a pair of upper and lower movable core holding pins 21 and 21, respectively, as shown in FIG.
[0018]
That is, each holding pin 21 penetrates the pair of left and right relief cutouts 20, 20. In a normal use state, the notch 20 has a slightly semicircular arc-shaped small engagement groove 20 a that partially engages with the outer peripheral surface of one holding pin 21, and a reference edge corresponding to the center of the notch 20. And a holding pin relief portion 20b that expands in the direction of the back wall 15b of the rectangular case portion 15 and widens (for example, rectangular shape, vertical elongated hole shape, etc.).
Further, small engaged portions (for example, small engagement holes, small grooves formed on the inner wall surface, etc.) 22 and 22 are formed at portions of the left and right side walls 15c and 15c near the upper and lower portions.
[0019]
Next, the movable core 3 will be described. As shown in FIGS. 1 and 4, the movable core 3 is formed in a box shape having openings at the front and rear. That is, 3a and 3a are upper and lower front walls, and in this embodiment, when locked, the tip of the sickle piece 7 can be engaged with the inner wall surface of one of the front walls 3a (sickle). The piece 7 is engaged with the movable core).
[0020]
3c and 3c are left and right side walls, 25 is a vertically long front opening formed between the front walls 3a and 3a, 26 is a vertically long recess formed in each of the front walls 3a and 3a, and 27 is these A plurality of screw holes formed in the recesses 26 and 26, 28 is a holding pin insertion hole formed above and below the left and right side walls 3c and 3c, and 30 is near the upper and lower parts of the left and right side walls 3c and 3c. And small engagement portions (for example, small protrusions) respectively engaged with and disengaged from the small engaged portions 22 and 22 of the troyoke 2 described above, 31 is a rear opening, and 32 is left and right side walls 3c and 3c. A vertical guide engagement long hole 33 having a required length formed in the center of each of them is a receiving bar member for a locking piece installed in a pair of left and right vertical guide engagement long holes 32, 32.
[0021]
Therefore, as shown in FIG. 1, the locking piece receiving bar member 33 falls by its own weight when the movable core 3 is in the vertical state. Accordingly, the receiving bar member 33 has arcuate edges 32a and 32a located below the pair of left and right vertical guide engagement slots 32 and 32 (when the movable core 3 is turned 180 degrees, the upper arcuate edge becomes downward. ) And a rotating cylinder 33b inserted through the slide engagement pin in a penetrating state.
[0022]
By the way, as shown in FIG. 1, the movable core 3 is held in a loosely fitted state on the trowel 2 via the engaging portion 30 and the upper and lower holding pins 21 and 21. When the movable core 3 is loosely fitted to the trowel 2, the small protrusion-like engaging portions 30, 30 of the movable core 3 are engaged with the small engaged portions 22, 22 of the troyoke 2, respectively. Accordingly, the troyoke 2 and the movable core 3 are integrated with each other, though temporarily.
[0023]
In addition, a slight clearance (for example, about 7 mm) is set between the lower surface of the locking piece 6 that has entered the movable core 3 and the receiving bar member 33, but the locking piece is tilted due to deformation of the door frame during an earthquake. It is the rotating cylinder 33b that 6 directly hits. Therefore, the movable core 3 moves to at least the Troyoke 2 side (the lower gap 46 and the rear gap 45 on the inner wall surface side) via the receiving bar member 33 that receives the locking piece 6 (see FIG. 8) . In addition, since the sickle piece 7 is also provided in the present embodiment, when the sickle piece 7 rises while retracting simultaneously with the locking piece 6, the upper edge portion of the front opening 25 of the movable core 3 becomes both The impact force is received from the locking pieces 6 and 7.
[0024]
Next, the cover-like strike 4 will be described with reference to FIG. 35 is a cover main body, 36 is a deformable inclined upper and lower end portion that is connected to the cover main body upward and downward, and 37 is provided so as to be orthogonal to the cover main body from the right end of the cover main body. The entrance engaging side wall 38 is a front opening having the same shape as the front opening 25 of the movable core 3, 39 is formed in the upper and lower portions of the cover body, and a total of two screw holes 27, 27 of the movable core 3, It is the insertion hole for the strike fixing tool 40 which each corresponds.
[0025]
The strike 4 does not have the other side wall facing the entry engagement side wall 37. Further, the upper and lower projecting end portions 37a and 37a and the inclined upper and lower end portions 36 and 36 of the approach engagement side wall 37 engaged with the notch groove 12 of the door frame 1 are cut off from each other.
[0026]
Therefore, the inclined upper and lower end portions 36 and 36 that cover the trolley sticking fixtures 41 and 41 of the strike 4, for example, press the strike 4 against the door frame side in the substantially horizontal direction X, or press the strike 4 against the end face side of the door 5. When an impact force in the reverse direction X is applied, it can be deformed.
[0027]
Next, the combination of each member is demonstrated easily. First, the troyoke 2 and the movable core 3 are combined together. At this time, both end portions of the slide engagement pin 33a of the receiving rod member 33 are engaged with the left and right vertical guide engagement long holes 32, 32, respectively. As a result, the rotating cylinder 33 b of the receiving bar member 33 is rotatably positioned in the left and right side walls of the movable core 3. Further, the engaging portions 30 of the movable core 3 are engaged with the engaged portions 22 of the troyoke 2. The upper and lower holding pins 21, 21 are inserted into the upper and lower cutout portions 20, 20 of the troyoke 2 and the upper and lower insertion holes 28, 28 of the movable core 3, respectively.
[0028]
Next, the case portion 15 of the troyoke 2 is fitted into the receiving port 11 of the left vertical frame of the door frame 1, for example, as shown in FIG. 2, and the upper and lower mounting pieces 17, 17 are in surface contact with the front wall 10 a of the door frame 1. Let Then, the Troyoke fixing tools 41 and 41 are screwed into the screw holes 13 and 13 of the door frame in accordance with the through holes 18 and 18 of the movable core. As a result, the trolley 2 is fixed to the door frame 1.
[0029]
By the way, when the movable core 3 is set in the vertical state as described above, the receiving bar member 33 falls downward by its own weight through the left and right vertical guide engagement long holes 32 and 32. Therefore, the receiving bar member 33 of the present embodiment can contact the lower surface of the locking piece 6 even if the movable core and the strike constituting the lock receiving member are rotated 180 degrees (inverted up and down). The frame 1 can be used freely on the left and right sides.
[0030]
Then, the strike 4 is made to cover the upper and lower mounting pieces 17, 17 of the troyoke 2. Thereafter, the strike fixing members 40, 40 are screwed into the screw holes 27, 27 of the movable core 3 in alignment with the insertion holes 39, 39, respectively. When screwed, the upper and lower holding pins 21 and 21 are surely engaged with the small engagement groove 20a of the troyoke, so that the members 2, 3 and 4 are integrated as shown in FIGS. In addition, there is some rear lance between the upper surface of the locking piece 6 and the upper edge of the front opening 28 of the strike 4.
[0031]
6 and 7 show an example of the moving direction of the movable core 3 when an earthquake occurs that causes the door frame 1 to deform. As described above, when the earthquake occurs, for example, when the locking piece 6 is deformed by the door frame 1 and the lower surface of the locking piece 6 and the receiving bar member 33 collide with each other, the movable core 3 moves the rotating cylinder 33b. Through the locking piece 6. At this time, the rotating cylinder 33b is rotated by the tilted locking piece 6. Therefore, even if the locking piece 6 is in pressure contact with the rotary cylinder 33b, the door is easily opened.
[0032]
Therefore, in the state of use of FIG. 1, an out-of-plane external force in the direction X intersecting the wall surface of the cover body 35 of the strike 4 is generated and at the same time parallel to the wall surface of the cover body 35. When an external force in the direction Y is generated, the strike 4 is shockedly pressed in the horizontal to vertical direction between the door frame 1 and the door 5, so that the upper and lower end portions 36 and 36 are outside. The front wall 10a of the door frame 1 is slid in the trolley direction X and the vertical direction Y by expanding and displacing. At this time, the small engagement protrusions 30, 30 of the movable core 3 are deformed or broken and come out of the small hole 22 of the trojoke 2.
[0033]
However, since the troyoke 4 and the movable core 3 are integrated with each other via the holding pin 21, the troyoke 4 and the movable core 3 are moved back and forth in multiple directions to the rear gap 45 and the upper and lower gaps 46 in the troyoke 1. To do. Therefore, the movable core holding pins 21 and 21 shift from the small engagement groove 20a of the notch 20 of the troyoke 2 to the wide holding pin escape portion 20b in response to the backward and upward movement of the movable core 3.
[0034]
