Description

【０００１】
【発明の属する技術分野】
本発明は、錠箱に対する操作部材（シリンダーユニット及びサムターンユニット）の取付け構造に関する。
【０００２】
【従来の技術】
錠箱の内外の幅広側壁には、操作部材と称されるシリンダーユニットとサムターンユニットを戸向きに対応してそれぞれ対向的に取り付ける必要がある。図９は本願発明の主要部を理解するための従来の概略説明図である。例えば錠箱１Ａを構成するケース身２Ａの嵌合孔１６Ａにシリンダーユニット３０Ａを装着する場合に於いて、該シリンダーユニット３０Ａが錠箱の嵌合孔から「ポロポロ」落ちないように、最低２本の挿入固定ピン５５Ａ、５５Ａをケース身２Ａの前壁５Ａの小孔１４Ａ、１４Ａからシリンダーユニット３０Ａを構成する外筒３１Ａの突起状係合部３３Ａ、３３Ａの貫通孔３４Ａ、３４Ａへと串状に突き刺す必要がある。
【０００３】
このような場合に於いて、従来の錠箱に対する操作部材３０Ａの取付け構造は、ケース身２Ａとは別個に成型された任意形状の位置決め案内片６０を、ケース身２Ａの幅広側壁に形成した縦方向係合孔に予め係合させ、この位置決め案内片６０がケース身２Ａの幅広側壁から外れないような係合状態にした上で、挿入固定ピン５５Ａ、５５Ａをケース身２Ａの前壁５Ａの小孔１４Ａ、１４Ａから位置決め案内片６０に形成した上下のガイド小孔６１、６１及びシリンダーユニット３０Ａの外筒３１Ａの係合部３３Ａに突き刺していた。
【０００４】
【発明が解決しようとする課題】
従来例である図９と、本願発明の一例である図８とを対比すれば明らかなように、従来の錠箱に対する操作部材の取付け構造に於いては、組立部品点数が多いために、錠箱に対する操作部材の取付け作業時間がかかる、錠箱自体がコスト高になるという問題点を有していた。そこで、本発明は、従来の問題点に鑑み、錠箱に操作部材を短時間で取付けることができること、錠箱のコストの低減化を図ること等を課題としている。
【０００５】
【課題を解決するための手段】
本発明の錠箱に対する操作部材の取付け構造は、錠箱１と、この錠箱１の内外の幅広側壁９、５１にそれぞれ固定的に装着される２個の操作部材３０、４０と、これらの操作部材を錠箱１にそれぞれ対設するために前記錠箱の前壁５の小孔１４から前記操作部材の突起状係合部３３、４４の各貫通孔へと串状に突き刺す細長状挿入固定ピン５５とから成り、前記幅広側壁は、前記前壁側から見て、縦断面上、錠箱１の内側に小突起状にそれぞれ上下左右に対向的に張り出し成形された複数個の挿入固定ピン用位置決め案内部１９、２４を有し、これらの挿入固定ピン用位置決め案内部は前記前壁と前記突起状係合部の各貫通孔との間で、かつ、上下方向に所定間隔を有して対設され、しかも、それらの外側湾曲面は、前記挿入固定ピン５５の通過をそれぞれ許容する案内通路１９ａ、２４ａを構成していることを特徴とする。
【０００６】
また本発明の錠箱に対する操作部材の取付け構造は、錠箱１と、この錠箱１の幅広側壁に固定的に装着される少なくとも１個の操作部材３０（４０）と、この操作部材を錠箱１にそれぞれ対設するために前記錠箱の前壁５の小孔１４から前記操作部材の突起状係合部の上下の貫通孔へと串状に突き刺す細長状挿入固定ピン５５とから成り、前記幅広側壁は、前記前壁側から見て、縦断面上、錠箱１の内側に小突起状にそれぞれ上下に対向的に張り出し成形された挿入固定ピン用位置決め案内部１９（２４）を有し、これらの挿入固定ピン用位置決め案内部は前記前壁と前記突起状係合部の各貫通孔との間で、かつ上下方向に所定間隔を有して対設され、しかも、それらの外側湾曲面は、前記挿入固定ピン５５の通過をそれぞれ許容する案内通路１９ａ（２４ａ）を構成していることを特徴とする。
【０００７】
【発明の実施の形態】
図１乃至図９に示一実施例を参照に本発明を説明する。
【０００８】
（１）発明の実施の環境と主要部材
図１を参照に発明の実施の環境について説明する。１は戸（開閉扉）の中に収められる彫り込み型錠箱である。この錠箱１には、錠前を構成する主たる部材、例えばデッドボルト、ダルマ、ラッチボルトなどが組み込まれている。そして、デッドボルトにはデッドカム軸等を介してシリンダーユニット（以下、「シリンダー」という。）やサムターンユニット（以下、「サムターン」という。）がそれぞれ連結され、一方、ラッチボルトにはハンドルカム軸等を介して内外のハンドルが連結されている。本発明の主要部材は錠箱１と、この錠箱１に固定的に装着されるシリンダー３０及びサムターン４０（ここでは、説明の便宜上「操作部材」ともいう。）、これらの操作部材３０、４０を錠箱１に対設固定するための複数本の挿入固定ピン５５である。
【０００９】
（２）錠箱の構成
図１を参照に錠箱１を構成する部材について説明する。錠箱１は、一側面開口のケース身２と、このケース身２の一側面開口部を閉鎖する板状ケース蓋３と、ケース身２の前壁に取り付けられる長板状のフロント４とから成る。まずケース身２について簡単に説明する。５は前壁、６は後壁、７は底壁、８は上壁、９は前記各壁と交差する幅広側壁、１０は一側面開口部である。
【００１０】
次にケース蓋３は、ケース身の前記一側開口部１０を閉鎖する矩形状の本体側壁（他方の幅広側壁）５１と、この本体側壁５１の先端部を折曲形成して連設した取付け壁５２とから成る。フロント４はこの取付け壁５２の前面に図示しない固着具を介して固定される。
【００１１】
（３）ケース身の前壁
ケース身２の前壁５の中央部には、デッドボルト用案内窓１１やラッチボルト用窓１２がそれぞれ形成されている。また前壁５の上下端部には、ネジ孔１３、１３がそれぞれ形成されている。さらに、前壁５の上端部側には、上下にそれぞれ一対をなして合計４個の挿入固定ピン用円型小孔１４、１４、１５、１５が形成されている。これらの円型小孔１４、１４、１５、１５は、各小孔の中心を直線で結ぶと、丁度縦方向の長方形が出来上がるように配設されている。
【００１２】
（４）ケース身の幅広側壁
ケース身の幅広側壁９は、錠箱１の外側の側壁に相当する。一方、ケース蓋３の本体側壁５１は、錠箱１の内側の側壁に相当する。したがって、錠箱１の一方の幅広側壁９には、図２に示すシリンダー３０が固定的に取り付けられ、また錠箱１の他方の本体側壁（幅広側壁）５１にはサムターン４０が取り付けられる。
【００１３】
図３ないし図６を参照にケース身２の幅広側壁９について説明する。ケース身２は鋼板でケース状に出来ているので、幅広側壁９にはプレス手段等により複数個の孔、固定ピン用位置決め案内部、操作部材用受け座部などが形成されている（本発明の関係のない固定軸用孔、ハンドル用軸孔などは省略している）。
すなわち、図３で示すように１６は第１操作部材としてのシリンダー３０を取り付けるための第１嵌合孔で、この第１嵌合孔１６にはシリンダーの一部を構成する外筒３１が嵌着する。
【００１４】
１７は幅広側壁９の内壁面から突出するようにプレスで成形された受け座部で、この受け座部１７は前記第１嵌合孔１６に臨むように幅広側壁９に連設し、かつ、中央部に前記第１嵌合孔１６と連通するダルマ用受け孔１８が形成されている。シリンダー用第１嵌合孔１６は、図３で示すようにケース身２の右上隅角部寄りの部位に形成され、上下方向の径が左右方向のそれよりも長い。
【００１５】
また１９、１９は、前記受け座１７と同様に幅広側壁９の内壁面から突出するようにプレスで成形された２個の挿入固定ピン用位置決め案内部である。これらの位置決め案内部１９、１９は、図３で示すように前壁５と受け座部１７との間で、かつ、上下方向に所定間隔を有して対設されている。
【００１６】
図４は挿入固定ピン５５と上下２個の位置決め案内部１９、１９との関係を示す縦断面であるが、この図４から明らかなように、２個の位置決め案内部１９、１９はケース身２の内側に小突起状にそれぞれ対向的に張り出し、その外側湾曲面は挿入固定ピンの通過を許容する案内通路１９ａ、１９ａとなっている。しかして、これら上下の案内通路１９ａ、１９ａは、前壁５の前述した外側（左側）上下の挿入固定ピン用小孔１４、１４と同一の水平線上に位置するように設定されている。
【００１７】
（５）ケース蓋の本体側壁
図１で示すように、ケース蓋３の本体側壁５１にもケース身２の幅広側壁９と同様に第２操作部材用の嵌合孔や受け座が設けられている。
【００１８】
すなわち、２１は第２操作部材としてのサムターン４０を取り付けるための第２嵌合孔で、この第２嵌合孔２１にはサムターンの一部を構成する外筒４１が嵌着する。
【００１９】
２２は本体側壁２１の内壁面から突出するようにプレスで成形された第２受け座部で、この第２受け座部２２は前記第２嵌合孔２１に臨むように本体側壁２１に連設し、かつ、中央部には第２嵌合孔２１と連通する受け孔２３が形成されている。なお、サムターン用第２嵌合孔２１も、図１で示すようにケース身２のそれと対向するように右上隅角部寄りの部位に形成され、上下方向の径が左右の径よりも長い。つまり、第１嵌合孔１６と第２嵌合孔２１は同一形状である。それ故に、戸の開閉向き如何によって、第１及び第２操作部材３０、４０を入れ替えることが可能である。
【００２０】
また２４、２４は、本体側壁５１の内壁面から突出するようにプレスで成形された２個の挿入固定ピン用位置決め案内部である。これらの位置決め案内部２４、２４は、図１で示すように前壁５の小孔１５、１５の位置を考慮し、取付け壁５２と第２受け座部２２との間で、かつ、上下方向に所定間隔を有して設けられている。
【００２１】
図４は前述したように固定ピン５５と上下２個の位置決め案内部２４、２４（１９、１９）との関係を示す縦断面であるが、この図４から明らかなように、右側の２個の位置決め案内部２４、２４は、ケース蓋３の内側に小突起状にそれぞれ対向的に張り出し、その外側湾曲面は固定ピン５５の通過を許容する案内通路２４ａ、２４ａとなっている。
【００２２】
したがって、錠箱１の幅広側壁の上端部は、縦断面上、ケース身３の内側に小突起状にそれぞれ上下左右に対向的に張り出した小突起部を有し、これらの小突起部の外側湾曲面は、合計４本の挿入固定ピン５５の通過を許容する案内通路１９ａ、１９ａ、２４ａ、２４ａを構成している。
【００２３】
（６）ケース蓋の取付け壁
図１で示すように、ケース蓋３の取付け壁５２の上下端部は、本体側壁５１よりも上下方向にそれぞれ突出している。しかして、２５、２５は上下端部にそれぞれ形成された皿状の取付け孔で、本実施例では、これらの取付け孔２５、２５を介して錠箱１が戸に固定される。
【００２４】
２６、２６、２７、２７は上端部側に形成され、かつ、上下にそれぞれ対をなす合計４個の三角型収納小孔で、これらの収納小孔２６、２６、２７、２７は、前壁５の固定ピン用円型小孔１４、１４、１５、１５とそれぞれ符合する。２８、２８はフロント４の上下一対の皿孔２９、２９と符合する透孔で、これらの透孔２８、２８は前壁５の上下のネジ孔１３、１３とそれぞれ符合する。なお、取付け壁５２には、特に符号を付さないが、デットボルト用の切欠部などが適宜に形成されている。
【００２５】
（７）操作部材
本実施例では、第１操作部材としてのシリンダー３０は、ケース身２の第１嵌合孔１６を介して受け座１７に装着される。このシリンダー３０は、図２で示すように図示しないキー操作によって回転する駆動軸を備えたシリンダー本体と、このシリンダー本体を包む外筒３１と、この外筒３１に摺動可能に設けられたミニスカート型二重構造カバー３２など複数個の部材から構成されている。そして、前記外筒３１の端部の外周壁面には、突起状の係合部３３、３３が上下に一対設けられている。またこれらの係合部３３、３３には、横方向に前壁５の固定ピン用円型小孔１４、１４に対向する貫通孔３４がそれぞれ形成されている。
【００２６】
一方、第２操作部材としてのサムターン４０は、ケース蓋３の第２嵌合孔２１を介して第２受け座２２に装着される。このサムターン４０も、図２で示すように操作摘み４２の操作によって回転する駆動軸部材と、この駆動軸部材を包む外筒４１と、この外筒４１に摺動可能に設けられたミニスカート型二重構造カバー４３など複数個の部材から構成されており、前記外筒４１の端部の外周壁面には、突起状の係合部４４、４４が上下に一対形成されている。そして、これらの係合部４４、４４にも、横方向に前壁５の固定ピン用円型小孔１５、１５に対向する貫通孔４５がそれぞれ形成されている。
【００２７】
（８）固定ピン
固定ピン５５は、図１で示すように合計４本である。これらの固定ピン５５は、楊枝状の細長棒状部５５と、この細長棒状部５５の後端部に鉤状に突出する薄板状係合頭部５７とから成る。
上記構成に於いて、操作部材３０、４０のそれぞれの固定方法は同一なので、説明の便宜上、第１操作部材としてのシリンダー３０をケース身２に固定的に装着する場合を中心に説明する。
【００２８】
図３で示すように４本の固定ピン５５は、前壁５の小孔１４、１４、１５、１５側から挿入するが、この場合まずケース蓋３の取付け壁５２の収納小孔２６、２７から挿入する。
【００２９】
図７は、挿入固定ピン５５を各操作部材の外筒３１、４１の貫通孔３４、４５にそれぞれ挿通した場合の説明図である。このように各操作部材の外筒３１、４１の位置決め案内部１９、２４に固定ピン５５を通すためには、錠箱１の第１及び第２嵌合孔１６、２１に前記外筒３１、４１の突起状係合部３３、４４を予めそれぞれ係合させた状態で固定ピン５５を上手に各孔に順次通す必要がある。
【００３０】
しかして、図８は、錠箱１の第１嵌合孔１６にシリンダー３０の外筒３１の突起状係合部３３を予め係合させた状態で、固定ピン５５を、まずケース蓋３の収納小孔２６とケース身２の小孔１４に通し、次にケース身の位置決め案内部１９に通し、次いで外筒３１の係合部３３に通し、これにより第１操作部材３０をケース身２に固定的に装着した場合である。この時固定ピン５５を完全に通すと、その鉤状頭部５７はケース蓋３の収納小孔２６内に完全に収まる。
【００３１】
したがって、第２操作部材４０を錠箱１に固定的に装着する場合も同様であり、錠箱１（ケース蓋）の第２嵌合孔２１にサムターン４０の外筒４１の突起状係合部４４を予め係合させた状態で、固定ピン５５を、まずケース蓋３の収納小孔２７とケース身２の小孔１５に通し、次にケース蓋の位置決め案内部２４に通し、次いで外筒４１の係合部４４に通し、これにより第２操作部材４０をケース蓋３に固定的に装着することができる。
【００３２】
【実施例】
錠箱の幅広側壁に形成した位置決め案内部の形状や大きさは特に問わない。要は幅広側壁にプレスなどの手段により突起状に連設形成され、かつ、細長状の挿入固定ピンを案内する位置決め機能を有する形状であれば良い。
【００３３】
ところで、本実施例では、錠箱１に２個の操作部材をそれぞれ固定的に装着する場合の一例であるが、例えば操作部材としてのシリンダーを錠箱に装着しない場合もあり得るので、このような場合には、操作部材１個、挿入固定ピン２本だけ、と言うことになる。
【００３４】
したがって、本発明の要旨は、「錠箱１と、この錠箱１の幅広側壁に固定的に装着される１個の操作部材と、この操作部材を錠箱１に固定的に装着するための複数本の細長状挿入固定ピンとから成り、錠箱１の前記幅広側壁は、縦断面上、ケース身３の内側に小突起状にそれぞれ上下に対向的に張り出した複数個の小突起部を有し、これらの小突起部の外側湾曲面は、合計２本の挿入固定ピン５５の通過をそれぞれ許容する案内通路１９ａ、１９ａ（２４ａ、２４ａ）を構成していることを特徴とする錠箱に対する操作部材の取付け構造」と言うことになる。
【００３５】
【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、錠箱に操作部材を短時間で取り付ける、錠箱のコストの低減化を図る等の課題を達成することができる。
