【０００１】
【発明の属する技術分野】
本発明は、パチンコ機、スロットマシン等のゲーム機の前面枠（前扉）を本体枠（筐体）に対し施錠する施錠装置に使用されるシリンダ錠の取付構造に関する。
【０００２】
【従来の技術】
パチンコ機、スロットマシンなどに使用される施錠装置は、一般に、縦長の基枠体の取付板にシリンダ錠が前面に突き出すように取り付けられ、シリンダ錠の錠軸の先端にカム板が固定され、そのカム板の係合部が回動時に連結杆に係合可能とされ、基枠体の上部と下部に枢支された鉤部材を、連結杆の摺動によって傾動させ、本体枠側の受け金具との係合を外し、解錠するように構成される。
【０００３】
ところで、この種の施錠装置のシリンダ錠は、通常、その外筒部の元部にフランジ部が形成され、そのフランジ部を基枠体の取付板の所定部位に当接させ、固定ねじを用いてフランジ部の上下２箇所を取付板に対し締付固定して取り付けている。
【０００４】
【発明が解決しようとする課題】
しかし、２箇所で固定ねじをねじ孔に差し込みながら締付固定するため、最初のシリンダ錠の位置決めや仮固定の作業が難しく、また、２箇所で固定ねじの締付作業を行う必要があるため、シリンダ錠の取付作業が煩雑化する問題があった。
【０００５】
本発明は、上記の点に鑑みてなされたもので、施錠装置の基枠体にシリンダ錠をより簡単に且つより少ない作業工数で取り付けることができるシリンダ錠の取付構造を提供することを目的とする。
【０００６】
【課題を解決するための手段】
上記目的を達成するために、本発明の請求項１のシリンダ錠の取付構造は、ゲーム機の施錠装置における基枠体の取付板に設けられた取付挿入孔にシリンダ錠の外筒部を挿入し、外筒部の末端に位置するフランジ部を取付板に当接させ、該フランジ部と取付板に設けた固定孔に固定ねじを挿入してシリンダ錠を取り付けるシリンダ錠の取付構造において、フランジ部が外筒部の末端近傍部分の外周の一方のみに突出して設けられ、外筒部の末端近傍部分の反フランジ部側の元部に係止突部が突設され、係止突部の接触面には円周方向に沿って傾斜した傾斜面が設けられ、取付板の取付挿入孔には係止突部が嵌入可能な切欠き部が設けられて構成され、シリンダ錠の外筒部を取付挿入孔に挿入すると共に、係止突部を切欠き部に挿入した後、シリンダ錠の外筒部をフランジ部と共に回動して係止突部を取付挿入孔の縁部に係止させ、フランジ部を１個の固定孔と１本の固定ねじを用いて取付板に固定することを特徴とする。
【０００７】
ここで、上記の取付構造においては、請求項２のように、シリンダ錠の外筒部末端近傍部分の係止突部を、取付挿入孔の切欠き部の対応位置から変位して設けることができる。
【０００８】
また、請求項３のように、フランジ部は、シリンダ錠の外筒部の末端に嵌入された合成樹脂製または金属製の取付用フランジ部材のフランジ部として形成し、取付用フランジ部材の円筒部の一部に係止突部を突設し、係止突部の接触面に傾斜面を設けて構成することができる。
【０００９】
また、請求項４のように、フランジ部の上面とその上面に接触する取付板の表面に、フランジ部を所定角度回動したときに相互に嵌合する位置決め突部と位置決め孔を設けることができる。
【００１０】
【作用】
上記構成のシリンダ錠の取付構造では、シリンダ錠を基枠体の取付板に取り付ける場合、先端のシリンダ錠を基枠体の内側から取付板の取付挿入孔に挿入し、その元部の円筒部の係止突部を、取付挿入孔の切欠き部に合わせて挿入する。そして、フランジ部を持ってシリンダ錠を所定角度回し、フランジ部の内側に突設された位置決め突部を、取付板側の位置決め孔に合わせるようにする。
【００１１】
このとき、係止突部が取付板の外側に嵌入し、係止突部がフランジ部の回動に応じて取付板の縁部を強く押圧し、取付板の取付挿入孔の縁部が、係止突部とフランジ部との間で挟持された状態となる。これにより、シリンダ錠は、所定の位置にがたつきなく位置決めされて装着された状態となり、最後に、固定孔に固定ねじをねじ込んで締め付け、シリンダ錠は取付板の取付挿入孔上に固定される。このように、係止突部を取付挿入孔の切欠き部に嵌めて回すだけの簡単な操作でシリンダ錠を所定位置に仮固定することができ、さらに1本の固定ねじを固定孔にねじ込むだけで簡単に固定することができる。また、係止突部の接触面には円周方向に沿って傾斜した傾斜面が形成されるから、フランジ部の回動に応じて徐々に取付板の縁部を強く押圧するように作用し、がたつきなく固定することができる。
【００１２】
【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はシリンダ錠の取付に使用する取付用フランジ部材１の正面図を示し、図２はその左側面図を、図３はその断面図を示している。この取付用フランジ部材１は、円筒部４の元部にフランジ部２が一方向にのみ円筒部４の軸方向と垂直に突き出すように突設されて構成され、硬質合成樹脂または金属により一体成形される。
【００１３】
円筒部４は、後述のシリンダ錠２０の外筒部２１がその上端に嵌着されるように、小径の嵌入部を段差をつけて形成し、さらにその外周部にかしめ受け溝７を設けて構成される。円筒部４の内側にはシリンダ錠２０の錠軸連結軸２２が嵌入する孔が形成され、錠軸連結軸２２はこの円筒部４内に嵌入され回動可能に支持される。
【００１４】
図１に示すように、取付用フランジ部材１は、円筒部４の一方の側のみ元部にフランジ部２が直角に突設され、他方の側の円筒部４の外周元部には、フランジ部２の軸心位置から左に所定角度だけ変位した位置に、係止突部３が突設される。この係止突部３は、後述の基枠体１０における取付板１１の取付挿入孔１２に設けた切欠き部１３と略同じ形状で、且つこの切欠き部１３内に進入可能に形成されている。
【００１５】
また、この係止突部３のフランジ部２に対する水平位置は、図３に示すように、フランジ部２の平面の水平位置より、取付板１１の板厚だけ上方にずれた位置に突設される。これによって、取付用フランジ部材１を取付板１１の取付挿入孔１２に差し込んで所定角度回したとき、取付板１１をフランジ部２と係止突部３との間で挟持し、取付用フランジ部材１を取付板１１に対し保持可能にしている。
【００１６】
さらに、この係止突部３の接触面には傾斜面３ａが円周方向に沿って傾斜して形成され、取付用フランジ部材１を取付板１１に対し回したとき、この傾斜面３ａが徐々に取付板１１を押圧するように作用し、取付板１１の挟持を確実に行うようにしている。図２において、８は円筒部４の外周部に突設した位置決め用突起であり、シリンダ錠２０の外筒部２１の末端に位置決め用凹部が形成され、その凹部がその位置決め用突部８に嵌め込まれることにより、シリンダ錠２０の外筒部２１の取付用フランジ部材１に対する円周方向の位置が決められる。
【００１７】
シリンダ錠２０としては、例えば、錠軸の周囲にその錠軸と平行な複数のタンブラーピンを配設した円環状のキー挿入口を有する構造のシリンダ錠が使用される。この種のシリンダ錠２０は、外ケースとなる外筒部内に錠本体を固定し、錠本体内に大径部を持った錠軸を回動可能に嵌入し、大径部と錠本体との間に複数のピン孔を軸方向と平行に穿設し、大径部の中央にはキー挿入口に突出するキー嵌入部を設けると共に、複数のタンブラーピンの先端をキー挿入口内に突出させる。そして、大径部と錠本体のピン孔に各々コードピンとタンブラーピンをコイルばねと共に挿入し、キー挿入口に差し込まれたキーの先端部によって、タンブラーピンがコードピンとタンブラーピンとの接触面を、錠軸の大径部と錠本体の摺動面と一致するように揃えて位置させたとき、解錠となるように構成される。
【００１８】
この実施例で使用されるシリンダ錠２０は、図５に示すように、その錠本体から取付用フランジ部材１までの長さを長くするために、シリンダ錠２０の本来の外筒部に接続用の外筒部２１を継ぎ足す形態で固定し、シリンダ錠２０の錠軸についても、長尺の錠軸連結軸２２をシリンダ錠の錠軸に連結した状態で取り付け、外筒部２１の軸心位置に回動可能に配設している。
【００１９】
しかし、このような外筒部２１付きの長いシリンダ錠を使用せずに、標準の長さのシリンダ錠のみを使用する場合は、上記のような外筒部２１、錠軸連結軸２２を使用せずに、標準的なシリンダ錠の外筒部を直接取付用フランジ部材１の円筒部４に固定し、そのシリンダ錠の錠軸の末端を円筒部４の軸孔に嵌入して使用すればよい。なお、長尺のシリンダ錠においては、錠軸連結軸を本来のシリンダ錠の錠軸と一体に形成することもでき、また、外筒部も本来のシリンダ錠の外筒部と一体に形成することもできる。
【００２０】
図５に示すように、シリンダ錠２０の外筒部２１の末端部が、取付用フランジ部材１の円筒部４に位置決めされて嵌入され、そのかしめ受け用溝７の位置で外筒部２１の一部外周を内側にかしめて押し込むようにして、かしめ固定される。また、同時に、錠軸連結軸２２の末端部が取付用フランジ部材１の軸孔に嵌入され、回動可能に支持される。このシリンダ錠２０と取付用フランジ部材１の固定時には、シリンダ錠２０の外筒部２１の末端に形成された位置決め用凹部に、取付用フランジ部材１の円筒部４の位置決め用突部８を嵌め込むことにより、シリンダ錠２０の外筒部２１の取付用フランジ部材１に対する円周方向の位置が決定される。
【００２１】
このような取付用フランジ部材１を備えたシリンダ錠２０は、図７〜図１０に示すように、ゲーム機用の施錠装置における基枠体１０の取付板１１の取付挿入孔１２に差し込むようにして装着される。基枠体１０の取付板１１には、図６に示すように、固定孔１４と位置決め孔１５が、上記フランジ部２の対応位置に穿設されている。基枠体１０は、取付板１１と支持板を断面Ｌ形に曲折して縦長に形成され、図では省略されているが、基枠体１０の支持板の上部と下部に枢支された鉤部材、上下の鉤部材を連結し基枠体に沿って摺動することにより鉤部材を傾動させて解錠する連結杆、シリンダ錠の操作に応じて連結杆を摺動させるカム板などを設けて構成される。
【００２２】
取付用フランジ部材１付きのシリンダ錠２０を基枠体１０の取付板１１に取り付ける場合、図１０に示すように、先端のシリンダ錠２０を基枠体１０の内側から取付板１１の取付挿入孔１２に挿入し、その元部の取付用フランジ部材１の係止突部３を、取付挿入孔１２の切欠き部１３に合わせて挿入する。そして、図７のように、取付用フランジ部材１のフランジ部２を持って、左に所定角度回して、フランジ部２の内側に突設された位置決め突部５を、取付板１１側の位置決め孔１５に合わせるようにする。
【００２３】
このとき、係止突部３が取付板１１の外側に入って嵌め込まれ、位置決め突部５が位置決め孔１５に嵌入して、図８のような状態となる。また、このとき、係止突部３の傾斜面３ａがフランジ部２の回動に応じて徐々に取付板１１の縁部を強く押圧するように作用する。このようにして、取付板１１の取付挿入孔１２の縁部は、係止突部３とフランジ部２との間で挟持された状態となり、シリンダ錠２０は、所定の位置にがたつきなく位置決めされて装着される。そして、この状態で、図９のように、固定孔６、１４に固定ねじ２３をねじ込み、シリンダ錠２０は、取付用フランジ部材１を介して取付板１１上に固定される。図９の例は、取付板１１の固定孔１４にめねじを設けて、そこに固定ねじ２３をねじ込み固定したが、取付板の固定孔にめねじがない場合はナットで固定ねじ２３を締め付けることもできる。
【００２４】
このように、取付用フランジ部材１の係止突部３を取付挿入孔１２の切欠き部１３に嵌め込み、所定角度回すことにより、フランジ部２と係止突部３で取付挿入孔１２の縁部を挟持させ、１本の固定ねじをねじ込むだけの操作で、簡単にシリンダ錠２０を取付板１１の所定位置に取り付けることができる。
【００２５】
なお、上記実施例では、通常の長さのシリンダ錠に長尺の外筒部を接続した長尺のシリンダ錠を使用したが、標準的な長さのシリンダ錠の外筒部に取付用フランジ部材を取り付け、上記と同様に、取付用フランジ部材を介してシリンダ錠を取付板に取り付けることもできる。また、取付用フランジ部材をシリンダ錠の外筒部と一体に形成することもできる。また、上記実施例では、フランジ部２の内側に位置決め突部５を設け、取付板１１側に位置決め孔１５を設けたが、それとは逆に、フランジ部２側に位置決め孔を設け、取付板１１側に位置決め突部を設けることもできる。
【００２６】
【発明の効果】
以上説明したように、本発明のシリンダ錠の取付構造によれば、係止突部を取付挿入孔の切欠き部に嵌め込むようにして、シリンダ錠の元部を取付板の取付挿入孔に嵌め込み、そのフランジ部を回して簡単に仮固定することができ、その状態で、固定孔に１本の固定ねじをねじ込み、簡単に少ない工数で固定することができる。また、フランジ部と係止突部で取付挿入孔の縁部を挟持して取付用フランジ部材が取り付けられるから、１本の固定ねじであっても、がたつきなく強固にシリンダ錠を固定することができる。
