【発明の属する技術分野】
本発明は、錠箱の引寄せ固定構造に関する。
【０００２】
【従来の技術】
関連する従来技術の一例として、出願人が先に提案した特開２００３−１２９７０１号公報を記載する。この公報に記載の実施例は、錠箱を扉の壁面に引寄せするものではないが、「錠構成部材（シリンダ錠）を、締付け手段（固着具）を介して扉の壁面に引寄せ固定する」という発明の構成と、「引寄せた際に扉の壁面を容易に変形させない」という発明の目的との関係では、本発明の技術と関連する。
【０００３】
また、出願人は、現時点で未公開ではあるが、日本国特許庁に対し、「錠箱のサムターン連結機構」の名称で、本発明に関連する先願を提出している。この先願発明の目的は、錠箱を長年使用していると、径年変化、衝撃等により、フロント板、或いは取付け板側の固着具が緩み、その結果、錠箱が左右に振れ、サムターンダルマ（デッドカム）と該サムターンダルマの嵌合孔に一体的に係合（嵌入）する異径断面のサムターン軸との中心軸線が一致しなくなり、両者の係合部分が互いに抉れるので、錠箱の振れ止めを防止するために、錠箱をフロント側とサムターン軸側の二箇所で固定するというものである。
【０００４】
【発明が解決しようとする課題】
本発明の主たる目的は、錠箱をフロント側とサムターン軸側の二箇所で固定する場合に於いて、錠箱を扉の内部空間を形成する一側壁側に固着具を介して引寄せたとしても、扉の壁面が容易に変形しないことである。また本発明の第２の目的は、長年使用による径年変化、衝撃等の要因により、錠箱が振れないようにすること。第３の目的は、扉の厚さ、サムターン座の厚さ、或いは取付け板の厚さ、錠箱の構造等の事情に対応して連結部材に螺合する筒状固定体を簡単に調整することができること。第４の目的は、前記筒状固定体をサムターン軸方向（扉の厚さ方向の意味）に微調整することができることである。第５の目的は、極力、扉に加工を施さないことである。
【０００５】
【課題を解決するための手段】
本発明の錠箱の引寄せ固定構造は、扉の内部空間に固定的に内装される錠箱に於いて、前記錠箱の幅広一側壁側に少なくとも２個のメネジ部を有する連結部材を固定的に設け、該連結部材に、環状板部に微調整するための放射状の係止爪を有すると共にサムターンの軸方向に調整可能な筒状固定体を螺合し、該固定体を適宜に調整した状態で扉の内壁面側から前記係止爪に係合すると共に、前記メネジ部にそれぞれ螺合する複数本の固着具を介して錠箱を引寄せ固定したことを特徴とする。
【０００６】
また、本発明の錠箱の引寄せ固定構造は、扉の内部空間に固定的に内装される錠箱に於いて、前記錠箱の幅広一側壁側に少なくとも２個のメネジ部を有する連結部材を固定的に設け、該連結部材に、係合部を有すると共にサムターンの軸方向に調整可能な筒状固定体を螺合し、該固定体を適宜に調整した状態で前記係合部に係合し、かつ、前記メネジ部にそれぞれ螺合する複数本の錠箱引寄せ用の固着具を備え、一方、扉の内壁面に扉孔と符合する開口部を有する取付け板が固定的に添設され、錠箱は、前記取付け板、前記筒状固定体、及び前記固着具をそれぞれ介して扉に引寄せ固定されていることを特徴とする。
【０００７】
また、本発明の錠箱の引寄せ固定構造は、扉の内部空間に固定的に内装される錠箱に於いて、前記錠箱の幅広一側壁側に少なくとも２個のメネジ部を有する連結部材を固定的に設け、該連結部材に、係合部を有すると共にサムターンの軸方向に調整可能な筒状固定体を螺合し、該固定体を適宜に調整した状態で前記係合部に係合し、かつ、前記メネジ部にそれぞれ螺合する複数本の錠箱引寄せ用の固着具を備え、一方、扉の内壁面に扉孔と符合する開口部を有する取付け板が固定的に添設され、さらに、該取付け板の外壁面に位置決めされた状態で支持板が添設固定され、錠箱は、該支持板、前記取付け板、前記筒状固定体、支持板及び前記固着具をそれぞれ介して扉に引寄せ固定されていることを特徴とする。
【０００８】
さらに、本発明の錠箱の引寄せ固定構造は、扉の内部空間に固定的に内装される錠箱に於いて、少なくとも２個のメネジ部を有する連結部材と、この連結部材に螺合すると共に、引寄せ用固着具と係合する係合部を有する筒状固定体と、扉の内壁面側から錠箱を引寄せ固定するために用いられる複数本の引寄せ用固着具とから成り、前記固着具は、外側ハンドル用取付け板及び該取付け板に添設された支持板をそれぞれ介して前記係合部に係合した状態で前記連結部材に螺合することを特徴とする。
【０００９】
【発明の実施の形態】
まず、図１乃至図９に示す第１実施例を参照にして説明する。この第１実施例の錠箱の引寄せ固定構造Ｘは、少なくとも２個のメネジ部１５．１５を有する連結部材７と、この連結部材に螺合すると共に、引寄せ用固着具と係合する係合部２３を有する筒状固定体２０と、扉１の内壁面４側から錠箱５を引寄せ固定するために用いられる複数本の引寄せ用固着具１６．１６とから成り、前記固着具は、取付け板３０又は／及び支持板４５を介して前記係合部２３に係合した状態で前記連結部材７に螺合することを特徴としている。
【００１０】
そこで、前記各構成要件について具体的に説明する。まず、図１は扉１の戸先側の内部空間２に錠前３が組み込まれている状態を扉の内壁面４側から見た説明図である。図１を基準にすると、錠箱５の幅広一側壁５ａの左上部には、連結部材用の錠箱開口６ａが形成されている。
【００１１】
本実施例では、図１、図７で示すように、連結部材７が錠箱５の幅広一側壁５ａの上部に形成された前記錠箱開口６ａに差し込んだ状態で、かつ、上下の差込アーム部或いは突起部分８．８を介して錠箱５に固定されている。各差込アーム部８．８には、仮想線で示す挿入棒９用の水平貫通孔が形成されている。
【００１２】
連結部材７はフロント板１０から前記差込アーム部８．８にそれぞれ串刺し状に差し込まれた上下の挿入棒９．９を介して錠箱５の幅広一側壁５ａ側に固定されている（図１、図７参照）。なお、連結部材７等が、錠箱５に予め固定されるか、又は後付固定されるかは本発明の特定要件ではない。
【００１３】
図２は、錠箱５に予め固定された連結部材７が、扉１の内部空間２に内装固定された状態を示す。この図２の状態に於いて、錠箱５は、フロント板１０等を介して一応錠箱５に固定されている。但し、錠箱５がフロント板１０を介して扉に固定されているだけでは、長年使用によって錠箱５が左右に振れる場合がある。そこで、本発明の主要部である連結部材７、これに螺合する筒状固定体、これに螺合する引寄せ用固着具等が錠箱５を扉１に固定する第２の固定部材として存在する。
【００１４】
図３は、連結部材７、筒状固定体、引寄せ用固着具等を示す。まず、連結部材７について説明する。１２は中心孔１３の内周壁に固定体用のメネジ１４を有する環状連結部である。この環状連結部１２は円形、楕円形、角形等その形態を問わない。環状連結部１２は、本実施例では外周壁１２ａが小判型状或いは楕円形状に形成され、該外周壁１２ａの上下の側壁には、前述した差込アーム部８．８がそれぞれ内側に連設している。
【００１５】
また１５．１５は、連結部材７の連結部１２の前壁１２ｂに形成された左右一対の固着具用のメネジ部で、これらのメネジ部１５．１５には、錠箱引寄せ用の複数本（本実施例では少なくとも２本）の固着具１６．１６（第１実施例では、第２の固着具）がそれぞれ螺合する。
【００１６】
次に筒状固定体２０について説明する。筒状固定体２０は、前述したように、連結部材７に螺合すると共に、固着具１６．１６と係止状態に係合する係合部を有する。
【００１７】
本実施例では、筒状固定体２０は、後述する取付け板３０又は／及び支持板４５の内壁面に面接触状態で当接する外壁面２１ａを有する環状板部２１と、この環状板部２１から突出し、かつ、連結部材７に螺合する筒状螺合部２２とから成る。
【００１８】
しかして、前記環状板部２１には、固定体２０を微調整するための放射状係合部（例えば係止爪）２３が、所定間隔を有して合計８個形成されている。また、前記筒状螺合部２２の外周壁には、連結部材７のメネジ１４に螺合するオネジ２４が形成されている。このように筒状固定体２０は、連結部材７に対して取り外し可能な螺合関係にあることから、筒状固定体２０を回転すると、該筒状固定体２０はサムンターン軸２５の軸方向へ進退動する。
【００１９】
換言すれば、連結部材７と一体的に螺合する筒状固定体２０の螺合位置を微調整することによって、取付け板３０側に進出し、又は取付け板３０から離れる。それ故に、前記係合部（係止爪）２３の数が増えるにしたがって微調整がより可能となる。
【００２０】
ところで、前記サムターン軸２５は、図７で示すように、サムターンの軸用の軸嵌合部材２６を介して錠箱内のサムターンダルマ（デッドボルト用のデッドカム）２７に嵌合する。もちろん、設形如何によって、異径断面のサムターン軸２５をダイレクトにサムターンダルマ２７の嵌合孔に嵌入しても良い。
【００２１】
図７に於いて、サムターンダルマ２７は、中心部に嵌合孔を有する断面ハット型形状の支持部材２８に回転可能に支持されているが、サムターン軸２５の連係構成や支持部材２８は本発明の特定要件ではない。
【００２２】
図４は扉１の内壁面４と、この内壁面に添設固定される取付け板３０を示す。図２で示すように、扉１の内壁面４にも、扉の外壁面と同様に扉孔が幾つか形成されている。すなわち、３１はサムターン部材のサムターン軸２５との関係で形成された比較的大きな扉第１嵌合孔或いは開口、３２は内側ハンドル軸との関係で形成された扉第２嵌合孔或いは開口、３３．３３は外側ハンドル用取付け座のメネジ杆３６．３６とそれぞれ螺合する第１固着具３７．３７用の扉貫通孔である。なお、扉貫通孔３３は扉第２嵌合孔３２と連通状態であっても構成・機能は同一である。
【００２３】
ここで、図１に関して補足説明をする。図１は扉１の内壁面４を一部切り欠いて錠箱５の幅広一側壁５ａを見せているが、該錠箱５の下部には、内側ハンドル用の嵌合孔６ｂが形成され、該嵌合孔６ｂからは内側ハンドル用のカム軸３８が見える。また錠箱５の係合部（小孔、切欠）６ｃ．６ｃには、外側ハンドル用取付け座３５のメネジ杆３６．３６が見える。
【００２４】
さて、前述したように、錠前３は内部空間２に内装された状態でフロント板、取付け長板等を介して扉１に固定的に取付けられている。そして、本実施例では、それに加えて、錠箱５は、連結部材７、筒状固定体２０、取付け板３０又は／及び支持板を介して扉１に固定されている。
【００２５】
そこで、図４は、取付け板３０と扉１の内壁面４との関係を示している。アルミニューム製の扉１は、壁面側から力が加わると、普通一般に変形し易い。そこで、第１実施例の取付け板３０は、扉に極力加工を施さないこと、扉の変形を防止すること等の理由から採用されている。
【００２６】
長板状の硬い取付け板３０は、サムターン軸２５を通すための開口部４１及び図示しない内側ハンドルを装着するための開口部を有している。また、扉１の左右の扉貫通孔３３．３３と符合すると共に、該取付け板３０を位置決めして扉１の内壁面４に添設した時に、外側ハンドル用取付け座３５のメネジ杆３６．３６と符合する第１固着具３７．３７用の取付け孔４３．４３も形成されている。
【００２７】
図５は、長板状の取付け板３０を、その円形開口部４１等が扉１側の開口３１．３２に一致するように位置決めされた状態で扉１の内壁面４に添設した状態を扉１の内壁面側から見た説明図である。取付け板３０は、仮想線で示した第１固着具３７．３７を取付け座３５のメネジ杆３６．３６にそれぞれ螺合することにより扉１に一次的に固定される。
【００２８】
図５で示すように取付け板３０の開口部４１及び扉１の開口３１の内径は、連結部材７の環状連結部１２や固定体２０の環状板部２１の外径よりも大きい。固定体２０が螺合していない場合には、連結部材７の前壁が完全に余裕を持って見える。
【００２９】
したがって、固定体２０を、取付け板３０の開口部４１又は扉１の開口３１から連結部材７に螺合することができるのみならず、室内側から指又は図示しないドライバーなどを用いて自由に回転（調整）することができる。
【００３０】
ところで、本実施例では、取付け板３０の外壁面に、さらに金属製の支持板４５を添設し、その後に、錠箱引寄せ用固着具１６．１６を連結部材７のメネジ部１５．１５に螺合させている。つまり、支持板４５、取付け板３０、固着具１６．１６、筒状固定体２０、及び連結部材７を介して錠箱５を扉の内部空間２内に引寄せ固定をしている。
【００３１】
図６乃至図９を参照にして支持板４５の構成を説明する。支持板４５は取付け板３０と略同一幅の矩形状に形成されている。支持板４５はサムターンを備えた制御箱４９を係合支持或いは固着具を介して固定することができれば十分であるから、制御箱４９の大きさを考慮してその幅や長さ寸法が設定されている（図９参照）。
【００３２】
しかして、４６は支持板４５の下端部の中央部に形成された切欠或いはサムターン軸２５用の嵌挿孔で、この嵌挿孔４６は連結部材７のサムターンダルマ２７の嵌合孔の軸線と一致する。したがって、支持板４５は、その嵌挿孔４６がサムターンダルマ２７に一体的に係合する軸嵌合部材２６の嵌合孔のそれとも完全に一致するように位置決めされた状態で取付け板３０の上面に添設される。
【００３３】
４７．４７は、支持板４５を位置決めした際に錠箱５の連結部材７のメネジ部（連結部）１５．１５と符合する第２の固着具１６．１６用の孔である。これらの孔４７．４７を介して連結部材７のメネジ部１５．１５に取付け板３０を間接的に扉１の内壁面４に固定するための第２の固着具１６．１６がそれぞれ螺合する。
【００３４】
４８は支持板４５の中央部（中央部寄りの部位も含む）に形成された矩形状の窓で、この窓４８を介して図示しない入力部材のリード線５０及びコネクタ５１が手前側に引き出される。
【００３５】
図８は、取付け板に設けた切欠凹所に入力部材側のコネクタ５１と、これに電気的に接続した制御箱側のコネクタ５２が収納された状態を示している。これによって、扉１の内壁面４にコネクタ用の収納凹所を加工追加しないで済むと共に、コネクタ５１．５２同士の接続も容易になる。本実施例では、支持板４５の具体的な構成は、発明の特定要件ではないので割愛する。
【００３６】
【実施例】
本発明では、図１乃至図９に示した錠箱の引寄せ固定構造Ｘを第１実施例とする。そこで、第１実施例を設計変更した他の発明を、それぞれ第２実施例、第３実施例、第４実施例として記載する。なお、これらの実施例を説明するにあたって、前記第１実施例等と構成・機能が同一の部分には、同一又は同様の符号を付して重複する説明を省略する。
【００３７】
図１０に示す第２実施例に於いて、前記第１実施例と主に異なる点は、支持板又は取付け板のいずれかを省略し、一枚の座板（支持板又は取付け板）３０Ａのみを用いたことである。この座板３０Ａには、中央部にサムターン軸２５用の開口４１Ａ或いは嵌挿孔４６Ａが形成されている。また、この開口４１Ａ（嵌挿孔４６Ａ）を基準にした座板３０Ａの左右の部位には、引寄せ用の固着具１６．１６が差し込まれる孔４７Ａ．４７Ａが形成されている。
【００３８】
このように構成しても、前記第１実施例と同様の効果を得ることができる。但し、発明の効果の点で、第１実施例では扉１に加工を施す必要がないのに対し、第２実施例では座板３０Ａの設形如何によって、扉１に固着具用の加工を施す必要性がある。
【００３９】
図１１に示す第３実施例（説明の便宜上、第２実施例の符号も援用する。）に於いて、前記第１実施例と主に異なる点は、第２実施例と同様に、一枚の座板（支持板又は取付け板）３０Ａのみを用いたこと、扉１にサムターン軸２５との関係で形成した開口３１Ａが小さいこと、該開口３１Ａとは別に引寄せ用の固着具１６．１６用の孔３４．３４が形成されていること、引寄せ用の固着具１６．１６を介して錠箱５を扉１の内壁面４側に引寄せると、筒状固定体２０は、扉１の内部空間２を形成する扉の壁面４ａに面接触することである。
【００４０】
すなわち、第１実施例では、扉１のサムターン軸用の開口３１の内径は、連結部材７の環状連結部１２や固定体２０の環状板部２１の外径よりも大きいのに対し、第２実施例の開口３１Ａは、例えば軸嵌合部材２６の外形寸法と略同一である。この第３実施例は、扉１に固着具用の加工を施す必要性があるものの、前記第１実施例と同様の効果を得ることができる。なお、この実施例の場合には、錠箱５の連結部材７に固定体２０を予め螺合調整した後に、固定体２０を備えた錠箱５を扉１の内部空間２に入れる必要がある点も、第１実施例と相違する。
【００４１】
図１２乃至図１５に示す第４実施例に於いて、前記第１実施例と主に異なる点は、筒状固定体２０Ａの構造、該筒状固定体２０Ａが、第１実施例のように、取付け板３０又は／及び支持板４５を介して扉１の内壁面４へと引寄せ固定されることである。この筒状固定体２０Ａは、引寄せ用固着具１６．１６を介して錠箱５を扉１の壁面に引寄せると、筒状固定体２０Ａのキャップ状外壁面２１ａが扉１のサムターン軸用の開口３１に入り込む。そして、該筒状固定体２０Ａの外壁面２１ａは、取付け板４５の内壁面に面接触可能である。しかして、この面接触可能な環状板部２１Ａの外壁面２１ａに周方向に複数個の調整孔（係合部としての係合孔）２３Ａが形成されている。
【００４２】
なお、前記調整孔２３Ａは、本実施例では円形孔を合計８個形成しているが、孔の形状や数を、真円とか、８個に限定するものではない。例えば調整孔２３Ａが長孔であれば、周方向に２個乃至６個程度形成することも可能である。
【００４３】
また、第４実施例の筒状固定体２０Ａは、筒状螺合部２２Ａの内周壁にメネジ２４Ａを形成している関係上、連結部材７Ａの環状連結部１２Ａの固定体用のオネジ１４Ａは、環状連結部１２Ａの外周壁に形成されている。このようにメネジとオネジの形成部位を任意に設計変更しても、第１実施例と同一の目的を達成することができる。
【００４４】
【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）錠箱をフロント側とサムターン軸側の二箇所で固定する場合に於いて、錠箱を扉の内部空間を形成する一側面側に固着具を介して引寄せたとしても、扉の壁面が容易に変形しない。
（２）長年使用による径年変化、衝撃等の要因により、錠箱が振れない。
（３）扉の厚さ、サムターン座の厚さ、或いは取付け板の厚さ、錠箱の構造等の事情に対応して連結部材に螺合する筒状固定体を簡単に調整することができる。
（４）実施例如何によって、筒状固定体をサムターン軸方向（扉の厚さ方向の意味）に微調整することができる。
（５）第１実施例は、扉や錠前に極力、錠前に必要な規制孔以外の孔或いは開口を形成しないで済む。
（６）サムターン軸とサムターンダルマの中心軸線を整合させることができる。

[0002]
[Prior art]
As an example of related prior art, Japanese Patent Application Laid-Open No. 2003-129701 previously proposed by the applicant is described. The embodiment described in this publication does not draw the lock box to the wall surface of the door, but “the lock component (cylinder lock) is pulled and fixed to the wall surface of the door via the fastening means (fixing tool). The relationship between the configuration of the invention “to do” and the object of the invention “does not easily deform the wall surface of the door when pulled” relates to the technique of the present invention.
[0003]
The applicant has filed a prior application related to the present invention under the name of “lock box thumb-turn coupling mechanism” to the Japan Patent Office, which has not been disclosed yet. The object of the invention of this prior application is that if the lock box has been used for many years, the fastener on the side of the front plate or the mounting plate will loosen due to changes in diameter, impact, etc. Since the center axis of the dead turn and the thumb turn shaft of different diameter cross sections that are integrally engaged (inserted) into the fitting hole of the thumb turn dharma do not coincide with each other, the engaging portions of both come into contact with each other. In order to prevent steadying, the lock box is fixed at two locations on the front side and the thumb turn shaft side.
[0004]
[Problems to be solved by the invention]
The main purpose of the present invention is that when the lock box is fixed at two locations on the front side and the thumb turn shaft side, the lock box is drawn to one side wall forming the inner space of the door via a fixing tool. The wall surface of the door is not easily deformed. A second object of the present invention is to prevent the lock box from shaking due to factors such as a change in the diameter due to long-term use and impact. The third object is to easily adjust the cylindrical fixed body that is screwed into the connecting member in accordance with the circumstances such as the thickness of the door, the thickness of the thumb turn seat, the thickness of the mounting plate, the structure of the lock box, etc. What can be done. The fourth object is that the cylindrical fixed body can be finely adjusted in the thumb turn axial direction (meaning the thickness direction of the door). The fifth purpose is to prevent the door from being processed as much as possible.
[0005]
