Description

【０００１】
【発明の属する技術分野】
本発明は、パチンコ機、スロットマシンなどの遊技機の前面枠（前扉）を本体枠（筐体）に対し施錠する施錠装置に関し、特に前面枠を本体枠に対しがたつきなく閉鎖し施錠することが可能な遊技機用施錠装置に関する。
【０００２】
【従来の技術】
遊技機の前面枠（前扉）を本体枠に対し施錠する施錠装置として、略断面Ｌ字状の取付板と支持板からなる基枠の内側に、摺動杆が摺動可能に配設され、支持板の上部と下部に鉤部が摺動杆に連結されて傾動可能に枢支され、取付板の中間部にシリンダ錠がその錠軸を取付板に設けた孔から内側に差込むように固定され、錠軸の先端に摺動杆と係合するカム部材が固定されてなる施錠装置が、一般に使用されている（例えば下記特許文献１などを参照）。
【０００３】

【０００４】
【発明が解決しようとする課題】
この種の施錠装置は、遊技機の前面枠の自由端の内側に、その鉤部を本体枠側に向けて縦に固定され、本体枠の内側には、上下の鉤部に対向する位置に、受け部が固定される。そして、前面枠を閉じたとき、その鉤部が受け部に当って傾動しまたは平行移動した後、ばねの付勢力により元の係止姿勢に戻ることにより、鉤部が受け部に係止され施錠される。
【０００５】
しかしながら、このような構造の施錠装置では、鉤部が受け部に対し係止動作を行う際、鉤部の傾動または平行移動を良好にするために、通常、鉤部と受け部の間に僅かな隙間を生じるようにしているか、或いはばねの付勢力に抗して鉤部が動き得る状態にしている。このため、施錠された遊技機の前面枠を持って開放方向に引いた場合、僅かではあるが前面枠にがたつきが生じ、それによって、前面枠と本体枠の間に隙間が生じる場合があった。このような隙間が前面枠と本体枠の間に生じた場合、その隙間から針金などを差し込んで不正解錠が行なわれる問題があった。
【０００６】
本発明は、上記の課題を解決するためになされたもので、筐体に対し前扉をがたつきなく閉鎖して隙間が生じないように堅固にロックすることができる遊技機用施錠装置を提供することを目的とする。
【０００７】
【課題を解決するための手段】
上記の目的を達成するために、本発明の施錠装置は、筐体側の内側に固定された受け部に、前扉側の内側に固定された嵌入ロック部を嵌入させて前扉を施錠する遊技機用施錠装置であって、受け部には嵌入ロック部を嵌入させる嵌入凹部が形成されると共に、嵌入凹部の内面に鋸歯状部が設けられ、嵌入ロック部のケーシング内には、係止部を突設した係止部材が係止部をケーシングから出入する方向に回動可能に枢支され、ばね部材が係止部をケーシングから突き出す方向に係止部材を付勢して配設されると共に、係止部材に係合して係止部を内側に戻す方向に回動させるための解錠部材が嵌入ロック部に配設され、解錠部材をシリンダ錠の錠軸に固定したカム板に連係させたことを特徴とする遊技機用施錠装置。
【０００８】
ここで、上記施錠装置においては、請求項２のように、受け部を筐体の上部と下部に取り付けると共に、嵌入ロック部が前扉における該受け部の対応位置に取り付けられ、上部と下部に取り付けられた嵌入ロック部の中間位置にフレームが前扉に対し固定されると共に、フレームにシリンダ錠が固定され、フレーム内にカム板をその錠軸に固定して配設することができる。
【０００９】
また、上記施錠装置においては、請求項３のように、嵌入ロック部のケーシング内に複数の係止部材が回動可能に枢支され、受け部の嵌入凹部内には複数の係止部材に対応して複数の鋸歯状部が係止部材の係止部に係止可能に配設され、複数の係止部材または複数の鋸歯状部の位置を相互に、係止部材の移動方向に沿ってずらして配置することができる。
【００１０】
【作用】
この遊技機用施錠装置は、遊技機の前扉を筐体に対し閉じると、前扉側の嵌入ロック部が筐体側の受け部の嵌入凹部内に進入する。このとき、嵌入ロック部のケーシングから外側に突出した係止部材の係止部が、嵌入凹部内面の鋸歯状部を乗り越えながら奥に向かって進入する。鋸歯状部には多数の鋸歯が進入方向に向かって配置され、係止部材はばね部材により鋸歯に係止される方向に付勢されるため、受け部の嵌入凹部内に一旦進入した嵌入ロック部は、係止部が鋸歯に噛合して係止され、後戻りすることができない。このため、前扉を筐体に対して閉じるに応じて、嵌入ロック部が受け部の奥まで進入し、その嵌入位置を保持するように係止部が鋸歯状部に係止される施錠状態となる。このとき、前扉を筐体側に閉じる閉鎖力に応じて、係止部が受け部の鋸歯状部を一つ一つ乗り越え、退行ができない状態となるため、施錠状態において前扉は筐体に対しがたつきなく、堅固にロックされ施錠される。
【００１１】
一方、それを解錠する場合は、キーによってシリンダ錠を回し、カム部材を回転させると、カム部材の回動によって、それの連係された解錠部材が係止部材をその係止部と鋸歯状部の係合を外す方向に回動させる。これにより、係止部材がその係止部と鋸歯状部の係合を外す方向にばね部材の付勢力に抗して回動し、嵌入ロック部の受け部に対するロック動作が解除され、嵌入ロック部が受け部の嵌入凹部内から退出し、前扉は解錠され開放される。
【００１２】
【発明の実施の形態】
以下、本発明の実施例を図面に基づいて説明する。図１は本施錠装置の前扉に取り付けられる嵌入ロック部１側の左側面図を示し、図２はその背面図を示している。また、図１２、図１３は筐体側に取り付けられる受け部２の斜視図等を示している。この施錠装置は、概略的には、筐体側の内側に固定された受け部２に、前扉側の内側に固定された嵌入ロック部１を嵌入させながらロックして前扉を施錠するように構成される。
【００１３】
図１２、図１３に示すように、受け部２には嵌入ロック部１を嵌入させる嵌入凹部２０が形成され、嵌入凹部２０の内面に２個の鋸歯状部２１，２２が設けられる。受け部２は断面が略コ字状に形成され、内部に矩形断面をもった嵌入凹部２０が形成されている。嵌入凹部２０は一方の端部に進入口を形成し、他方の端部も開口して形成される。進入口は嵌入ロック部１が進入しやすいように、斜めに開口した開口部を有した形状、つまり前部の開口部を傾斜して切断し形状に形成されている。さらに、受け部２は、両側の側壁により、進入した嵌入ロック部１を挟んで保持するように形成され、一方の側壁内面に２つの鋸歯状部２１，２２が形成されている。
【００１４】
この鋸歯状部２１，２２の形状は、図１２，１３に示すように、鋸歯の先端の方向が斜め奥を向くように形成され、嵌入ロック部１が進入しその係止部１３，１４が鋸歯状部２１，２２に係止されたとき、鋸歯を乗り越えて進入可能で、後退ができない形状に形成されている。さらに、この２つの鋸歯状部２１，２２はその位置を前後方向つまり進入方向に鋸歯の半ピッチだけずらして配置されている。これにより、鋸歯状部２１，２２の鋸歯の大きさをある程度確保しながら、嵌入ロック部１の嵌入ロック位置を細かくセット可能としている。
【００１５】
一方、嵌入ロック部１は、図３〜図６に示すように、そのケーシング１０が受け部２の嵌入凹部２０内に嵌入可能な形状に形成され、ケーシング１０内には、係止部１３，１４を突設した２個の係止部材１１，１２が係止部１３，１４をケーシング１０から出入する方向に、各々独立して回動可能に枢支されている。さらに、ばね部材１７が２個の係止部材１１，１２の係止部１３，１４を、ケーシング１０内から外側に突き出す方向に係止部材１１，１２を付勢して配設される。ばね部材１７は捻りコイルばねから構成され、ロッド１６に外嵌して取り付けられる。また、ケーシング１０内には係止部材１１，１２の係合部１１ａ，１２ａに係合して係止部１３，１４を内側に戻す方向に回動させるための解錠部材１５が上下方向に摺動可能に配設されている。
【００１６】
嵌入ロック部１のケーシング１０は、図７に示すように、平板部の両側に直角な側壁部を設けた断面コ字状に形成され、その端部に固定用の固定フランジ１０ｃを設け、平板部に上記係止部１３，１４を突き出すための２つの開口部１０ａ，１０ｂを設けて形成される。さらに、ケーシング１０の先端部に軸孔を有した軸支部が形成され、その軸支部の軸孔には、２個の係止部材１１，１２を回動可能に支持したロッド１６が嵌入され、ロッド１６を介して係止部材１１，１２はケーシング１０内で独立して回動可能に支持される。
【００１７】
２個の係止部材１１，１２は、図９、図１０に如く、略同様な形状に形成され、ケーシング１０と同様に、平板部の両側に直角な側壁部を設けた断面コ字状に形成され、平板部に係止部１３，１４を外側に切り起こし、斜め上方に突き出すように、つまり嵌入ロック部１の反進入方向に向けて斜めに傾斜して形成される。また、その末端にはロッド１６が貫通する軸孔を設けた軸支部１１ｂ、１２ｂが設けられ、さらに、係止部材１１、１２の先端には、下側に曲げた部分に係合部１１ａ，１２ａが設けられる。
【００１８】
この係合部１１ａ，１２ａは、解錠部材１５の傾斜した係合部１５ａ，１５ｂと係合可能に配設され、解錠時、解錠部材１５が上方に摺動したとき、係合部１１ａ，１２ａが傾斜した係合部１５ａ，１５ｂに押されて、係止部材１１，１２を内側に回動させ、係止部１３，１４を内側に入れるように動作する。このように、２個の係止部材１１，１２は、ケーシング１０の内側に並んで配設され、その元部の軸支部１１ｂ、１２ｂがロッド１６により独立して回動可能に支持される。そして、係止部１３，１４をケーシング１０の開口部１０ａ、１０ｂから外側に突き出すように、両係止部材１１，１２を付勢するためのばね部材１７が、ロッド１６に外嵌されて装着されている。なお、２個の係止部材１１，１２の係止部１３，１４は、受け部２側の鋸歯状部２１，２２の鋸歯の位置が相互にずれている場合、同じ位置でよいが、鋸歯状部２１，２２の鋸歯の位置が相互にずれていない場合、図のように、その進入方向の前後位置を鋸歯の半ピッチづつずらして配置する。
【００１９】
さらに、ケーシング１０内には、解錠部材１５が、傾斜した部分を有する係合部１５ａ、１５ｂを、係止部材１１，１２の先端の係合部１１ａ，１２ａに係合可能に且つ上下方向に摺動可能に配設される。そして、コイルばね１８が、ケーシング１０と解錠部材１５の間に、解錠部材１５を下方につまり非解錠方向に付勢して掛けられている。
【００２０】
解錠部材１５は、図１１に示すように、平板を略コ字状に曲げた形状に形成され、一方の側の上部と下部に係合部１５ａと１５ｂが設けられ、他方の側に連結杆５が連結される連結部１５ｄが孔を有して形成される。２つの係合部１５ａ，１５ｂは、上部に傾斜部を有して形成され、解錠部材１５の上方移動時、この傾斜部が係止部材１１，１２の先端の係合部１１ａ，１２ａに当り、係止部材１１，１２を内側に回動させ、その係止部１３，１４を内側に入れて係止を外すように作用する。なお、係止部材１１，１２の係止部１３，１４の先端は、直角な矩形先端面を有して形成され、その先端角部が受け部２側の鋸歯状部２１，２２に斜めから噛合したとき、そのまま強固に係止されるような傾斜角度に形成されている。
【００２１】
このような構成の嵌入ロック部１は、図１、図２に示すように、施錠装置の上部と下部に同じものが同じ向きに配設され、それら上下の嵌入ロック部１，１の解錠部材１５に、シリンダ錠７の箇所から上方と下方に延設された連結杆５の上端部と下端部が連結されている。連結杆５は、シリンダ錠７を取り付けたフレーム９内に上下摺動可能に装着されている。フレーム９は取付板と支持板をＬ字状に曲折して縦長の枠状に形成され、その取付板に、シリンダ錠７を取り付けるための孔が形成され、シリンダ錠７はそのフレーム９の取付板の孔に、外側からその錠軸を挿入するように差し込み、フランジ部をねじ止めして固定される。
【００２２】
さらに、シリンダ錠７の錠軸にはカム部材８が固定され、カム部材８には、その回動時に連結杆５の対応位置に設けた係合部と係合する係合凸部が設けられる。連結杆５はフレーム９内の支持板に沿って上下摺動可能に配置され、そこにはカム部材８の係合凸部が係合可能な係合部が設けられ、シリンダ錠７にキーを差し込んで回した際、錠軸とカム部材８が回動し、そのとき、係合凸部が連結杆５を押して上方に移動させる。なお、図１，２において、フレーム９は上下の嵌入ロック部１，１と分離した構造で図示されているが、勿論、上下の嵌入ロック部１，１のケーシング１０とフレーム９は、一体にまたは一体的に連結して構成することもできる。
【００２３】
このように構成された施錠装置は、図１４，１５に示すように、その嵌入ロック部１を有する本体側が、遊技機における例えば合成樹脂製の前扉３１の内側に、シリンダ錠７の先端を前面に露出させ、嵌入ロック部１を遊技機の筐体３０側に突出した状態で取り付けられる。この例では、シリンダ錠７を取り付けたフレーム９が前扉３１の中間部に固定され、その上方に上部の嵌入ロック部１がケーシング１０の固定フランジ１０ｃを前扉３１にねじ止めして固定され、その下方に下部の嵌入ロック部１が同様にその固定フランジ１０ｃを前扉３１にねじ止めして固定される。
【００２４】
一方、筐体３０の内側の嵌入ロック部１，１に対応した上下位置（側壁の一部）には、図１５のように、受け部２、２がその進入口を前方に向けて配設され、固定ねじで固定される。
【００２５】
このような遊技機用施錠装置は、遊技機における前扉３１を筐体３０に対し閉じると、図１４、図１５に示すように、上下の嵌入ロック部１，１が筐体３０側の受け部２，２の嵌入凹部２０内に進入する。
【００２６】
このとき、上下の嵌入ロック部１，１は、その平板部の開口部１０ａ，１０ｂから外側に突き出した係止部１３，１４を、受け部２，２の内側の鋸歯状部２１，２２に接触させながら進入していく。つまり、前方に傾斜して配設された係止部１３，１４の先端が、鋸歯状部２１，２２に接触し、鋸歯を乗り越えながら、嵌入凹部２０の奥に進入していく。
【００２７】
このとき、係止部材１１，１２は、ばね部材１７により、その係止部１３，１４を突き出す側に付勢されているから、そのばね力に抗して僅かに回動するように作用し、係止部１３，１４が鋸歯を乗り越えることになる。またこのとき、嵌入ロック部１，１には、各々２個の係止部材１１，１２が配設され、その各々が受け部２側に設けた２つの鋸歯状部２１，２２に接触しながら進入し、２つの鋸歯状部２１，２２はその鋸歯のピッチがその進入方向で半ピッチずれて形成されているため、鋸歯状部２１，２２の鋸歯が大形であっても、嵌入ロック部１，１に進入してロックされる係止部材１１，１２の係止部１３，１４の移動ピッチは、その半ピッチとなり、細かい移動に伴い係止（ロック）を繰り返しながら、嵌入ロック部１，１は受け部２、２内に進入していく。
【００２８】
つまり、前扉３１を筐体３０に対し閉じていくと、嵌入ロック部１，１は受け部２、２内に徐々に進入していくが、鋸歯状部２１，２２の鋸歯の半ピッチづつの非常に細かい僅かな押し込み量で、嵌入ロック部１，１が受け部２，２に対し徐々にロックされていくため、図１６に示すように、最終的に前扉３１を閉じた状態では、扉と筐体の間に殆ど隙間が生じず、前扉３１はがたつきのない状態で筐体３０に対し堅固にロックされる。
【００２９】
前扉３１を解錠する場合は、キーをシリンダ錠７に差し込みその錠軸を回し、カム部材８を図２の反時計方向に回転させると、カム部材８の回転により、カム部材の係合部が同方向に回動して連結杆５側の係合部に係合し、その係合部つまり連結杆５を上方に摺動させる。このとき、連結杆５が上昇すると、上下の嵌入ロック部１，１内の解錠部材１５、１５が上方に移動し、解錠部材１５，１５に設けられた係合部１５ａ，１５ｂが係止部材１１，１２の先端の係合部１１ａ，１２ａ（傾斜部）に当る。このとき、係止部材１１，１２が内側への回動力を受けてロッド１６を軸に図１６の下側に回動し、その係止部１３，１４が内側に入って、受け部２の鋸歯状部２１，２２との係止を外す。これにより、嵌入ロック部１，１のロックが解除され、受け部２，２の嵌入凹部２０，２０から嵌入ロック部１，１が退出し、前扉３１は開放される。
【００３０】
このように、本施錠装置では、前扉３１を筐体３０に対し閉じるに応じて、上下の嵌入ロック部１，１が受け部２，２内に進入し、嵌入ロック部１，１の係止部１３，１４が受け部２，２の内側の鋸歯状部２１，２２に接触しその鋸歯を乗り越えながら奥に進入していく。このために、筐体３０に対し前扉３１を閉じて押し込んだとき、その押し込み量に応じて、嵌入ロック部１，１が受け部２，２に進入しロックされる状態となり、最終的に前扉３１を閉じた状態では、殆ど隙間が生じない状態となり、前扉３１を筐体３０に対しがたつきのない状態で堅固にロックすることができる。
【００３１】
また、受け部２内に設けた２つの鋸歯状部２１，２２はその鋸歯のピッチがその進入方向で半ピッチづつずれて形成され、或いは嵌入ロック部１，１内の２つの係止部材１１，１２の係止部１３，１４の位置が進入方向に半ピッチづつずれて配設されているため、鋸歯状部２１，２２の鋸歯の大きさを強度保持のために比較的大形とした場合でも、嵌入ロック部１，１が進入してロックされるピッチは、その鋸歯の半ピッチとなり、細かい押し込み量でロックすることが可能となり、筐体３０に対し前扉３１を一層隙間なく且つがたつきなく施錠することができる。
【００３２】
【発明の効果】
以上説明したように、本発明の遊技機用施錠装置によれば、前扉を筐体に対し閉じると、嵌入ロック部が受け部内の嵌入凹部に進入し、嵌入ロック部のケーシングから突出した係止部が受け部内の鋸歯状部の鋸歯に接触しながら進入し、嵌入ロック部は退行できない状態で受け部内に進入してロックされ、前扉を筐体に対して閉じる動作に応じて、嵌入ロック部の係止部が退行不可能な状態で受け部の鋸歯状部の鋸歯を一つ一つ乗り越えて進みロックされるから、前扉を筐体に対し押し付けるように閉鎖して施錠した場合、前扉と筐体の間に殆ど隙間が生じず、前扉をがたつきのない状態で、堅固に施錠することができる。
【００３３】
また、受け部内に配設した２つの鋸歯状部の鋸歯のピッチを、相互にその進入方向で半ピッチづつずらして形成し、或いは嵌入ロック部内の２つの係止部材の係止部の位置を進入方向に半ピッチづつずらして配置すれば、鋸歯状部の鋸歯の大きさを強度保持のために比較的大形とした場合でも、嵌入ロック部が進入してロックされるピッチは、その鋸歯の半ピッチとなり、細かい押し込み量でロックすることが可能となり、筐体に対し前扉を一層隙間なく且つがたつきなく施錠することができる。
