Description

【０００１】
【発明の属する技術分野】
この発明は、遊技機の前面枠を本体枠に対して施錠させる施錠装置に関するものである。さらに詳しくは、この発明は、パチンコ、パチスロ、スロットマシン、スマートボール、アレンジボール等に例示される遊技機の前面枠を本体枠に対して施錠したり解錠したりするのに好適な施錠装置に関するものである。
【０００２】
【従来の技術】
遊技機の前面枠は、一端が蝶番で本体枠に固定され、他端は自由端とされて本体枠に対し回動可能となっており、前面枠の自由端の背面に、本体枠に設けられた受け金具との施錠を可能とする施錠装置が取り付けられている。
【０００３】
従来より、例えば、登録実用新案第２５０８４５２号公報に記載の如き構造の施錠装置が知られており、これを図１６に示す。図１６では、受け金具、前面枠、および、本体枠も示している。この施錠装置７０は、概略、縦長の取付板７１の側方に支持板７２が起立した基枠体７３の内側に、施錠杆７４が支持板７２に沿って上下に摺動可能に配設され、施錠杆７４が引張バネ７５により施錠方向に付勢され、支持板７２の上部と下部に設けられた支軸７６、７６を中心に回動可能に軸支された鉤部材７７、７７と、施錠杆７４の上下端とがそれぞれ連結ピン７８、７８で連結され、前記取付板７１の中間部にシリンダ錠７９が取り付けられた構造をしている。
そして、ガイドピン８０が、施錠杆７４に穿設された長孔８１に挿通されて支持板７２に固定され、施錠杆７４がガイドピン８０によって案内されることで、施錠杆７４が支持板７２に沿って上下に摺動するようになっている。
【０００４】
このような施錠装置が設けられた遊技機においては、図示していない蝶番を支点にして前面枠８２を本体枠８３に対して閉鎖すると、本体枠８３に設けられた受け金具８４に鉤部材７７が当接し、鉤部材７７が上方に回動するとともに施錠杆７４が下方へ摺動する。そして、鉤部材７７の鉤爪部７７ａの先端が受け金具８４の上端縁を乗り越えると、施錠杆７４が引張バネ７５の復元力により施錠位置に戻り、受け金具８４に鉤部材７７が係合し、前面枠８２が本体枠８３に施錠される。そして、図示していないキーをシリンダ錠７９に差し込み、キー操作によりカム板８７を解錠方向に回動させて、施錠杆７４を下方に摺動させ、鉤部材７７を上方に回動させて受け金具８４と鉤部材７７との係合を解除し、蝶番を支点として前面枠を開くことができる。
【０００５】
この施錠装置７０の鉤部材７７と受け金具８４との係合関係について、さらに、詳細に説明する。
ここにおいて、上下の鉤部材７７、７７と受け金具８４、８４との係合関係は同一なことから、上方の鉤部材と受け金具に基づいて説明し、下方の鉤部材と受け金具については説明を省略する。図１７は施錠装置の上方部と受け金具の関係構造を示す部分拡大説明図である。なお、便宜上、本体枠と前面枠の図示は省略している。図１７に示されるように、鉤部材７７は、その下側縁に略台形状の切欠７７ｂが設けられ、該切欠７７ｂにより鉤部材７７の先端側に鉤爪部７７ａが形成され、該鉤爪部７７ａの切欠側は直線状の係合用縁７７ｃとなっており、施錠位置における前記鉤部材７７の係合用縁７７ｃは、施錠杆の摺動方向Ｘと平行（すなわち、前記施錠杆の摺動方向Ｘと直交し前記支軸７６の軸心を通る直線Ｙと直交）に設定されている。そして、切欠７７ｂの深さ、すなわち、切欠７７ｂの底縁７７ｄは、前記直線Ｙを越えた深さに及んでいる。
【０００６】
受け金具８４は板状であって、施錠状態において、図１７に示されるように、受け金具８４の上端縁が鉤部材７７の切欠７７ｂの底縁７７ｄと当接または底縁７７ｄ近傍にまで達しており、受け金具８４と鉤部材７７の係合用縁７７ｃが係合することになり、施錠状態において、前面枠を無理にこじ開けようとする力に抵抗することになる。
【０００７】
この鉤部材７７を受け金具８４に係合させて施錠したり、受け金具８４との係合を外して解錠するためには、鉤部材７７は、図１７の実線と２点鎖線で示すよう回動できること、すなわち、施錠状態における受け金具８４と鉤爪部７７ａとの間に、鉤部材７７が支軸７６を中心に回動できるだけの間隙ｔを設けることが必要である。
一方、この間隙ｔは、本体枠と前面枠との間のガタとして機能し、ガタの大きさによっては、例えば、先端にフックが形成された帯状で薄い鋼板や先端が折り曲げられてフックが形成されたピアノ線のような操作具をガタの間から挿入し、フックの先端を鉤部材７７に引っかけて引っ張り、鉤部材７７を支軸７６を中心に解錠方向に回動させると、受け金具８４と鉤部材７７との係合を解除でき、蝶番を支点として前面枠８２を開くことができることになる。このようにして、前面枠８２が開放されると、前面枠８２の背面に配設された機器や部品への操作が可能となり、これら機器や部品を改変したり、遊技機の勝率を制御するＲＯＭを勝率の高い裏ＲＯＭと交換するといった不正操作が可能となる。鉤部材７７の切欠７７ｂの底縁７７ｄまでの深さを深くする程間隙ｔを大きくすることが必要となることから、ガタもより大きくなることになる。
【０００８】
そして、必要とするガタよりも無理にガタを少なくするように受け金具８４を本体枠に取り付けたり、または、施錠装置７０の前面枠への取り付けや受け金具８４の本体枠への取り付け誤差等によって、受け金具８４と鉤爪部７７ａとの間隙ｔが不十分となった場合は、図１８に示すような不完全な施錠状態となり、この状態において、前面枠を無理にこじ開けようとする力が働くと、鉤部材７７と受け金具８４との係合点が徐々にずれ、鉤部材７７は支軸７６を中心に解錠方向に回動してゆき、比較的少ない力でも係合が外れ、前面枠が開いてしまうことになる。
【０００９】
そこで、遊技機の組立時等において、施錠時における受け金具８４と鉤部材７７との間隙ｔが不十分な場合や過大な場合を想定して、適正な間隙ｔに調整ができるように、受け金具８４の板厚をペンチ等で曲げることができる程度としている。しかしながら、受け金具８４をペンチ等で曲げて間隙ｔを調整する必要のある場合、前面枠を閉めた状態では、受け金具８４と鉤部材７７との関係は、前面枠が邪魔になって、直接確認ができない。間隙ｔの調整は、前面枠を開いて行うことになるが、カンに頼らざるを得ず、不正確になりやすく、また、適正な間隙ｔになるまで、調整を繰り返す必要があり、手間がかかり、コスト高に繋がる。
【００１０】
また、前述のように、受け金具は、ペンチ等の道具で曲げることができる程度の板厚であることから、強度が十分とは言い難く、施錠状態において、前面枠を不正操作等の目的で無理にこじ開けようとすると、受け金具が比較的容易に変形してしまい、前面枠が開けられてしまうことになる。
【００１１】
図１９に示すように、鉤部材７７の切欠７７ｂの深さを浅くして、施錠杆７４の摺動方向Ｘと直交し支軸７６の軸心を通る直線Ｙまでの深さとすると、図１７に示したような間隙ｔ（すなわち、ガタ）を受け金具８４と鉤爪部７７ａとの間に設けなくとも、図１９の実線と２点鎖線で示すように鉤部材７７を受け金具８４に係合させて施錠させたり、または、受け金具８４との係合を外して解錠させることができることになる。しかしながら、鉤部材７７の切欠７７ｂが浅いため、施錠状態における受け金具８４との係合が不十分となりやすい。図２０に示すように鉤爪部７７ａの先端を下方に延ばせば、施錠状態における受け金具８４と鉤部材７７との係合が十分となるが、鉤部材７７が大きくなり、コスト高となる。
【００１２】
ところで、従来の施錠装置７０は、図２１に示されるように、その構造上、施錠杆７４と連結された鉤部材７７が支軸７６の軸心を中心に回動するのに支障がないように、支持板７２には、連結ピン７８のかしめ部の逃がし用の湾曲長孔９０を穿設することが必要とされ、そして、施錠装置７０の組立においては、鉤部材７７の軸孔９１に支軸７６を挿通し、支軸７６を支持板７２にかしめ止めすること、および、鉤部材７７と施錠杆７４とを連結ピン７８でかしめて連結することが必要であり、製造上、多くの工程を必要とする。そして、このような構造においては、鉤部材７７を回動可能とする支軸７６の軸線と、鉤部材７７と施錠杆７４を連結する連結ピン７８の軸線とが平行となっていないと、鉤部材７７の回動、および／または施錠杆７４の摺動に無理な力を必要としたり、きしんだりすることから、鉤部材７７と受け金具８４との係合が円滑に行われなかったり、係合状態が不十分であったり、キー操作による解錠が円滑に行い難いといった欠点が指摘されていた。
【００１３】
【発明が解決しようとする課題】
この出願の発明は、上記のような実情に鑑み鋭意研究の結果創案されたものであり、受け金具との施錠または解錠が円滑で確実であり、しかも、容易に行うことができる遊技機の施錠装置、とりわけ、受け金具との施錠または解錠が円滑で確実であり、しかも、容易に行うことに加え、不正解錠等の不正操作を防止できることにもなる遊技機の施錠装置を提供することを目的とする。
【００１４】
【課題を解決するための手段】
上記課題を解決するため、この発明は、縦長の取付板の側方に支持板が起立した基枠体の内側に、施錠杆が前記支持板に沿って上下に摺動可能に配設され、該施錠杆が引張バネにより施錠方向に付勢され、前記取付板が本体枠に対し開閉可能とされた前面枠に取り付けられ、前記支持板の上部と下部に設けられた支軸を中心に軸支され、前記施錠杆の摺動に連動して施錠位置と解錠位置との間で回動可能な鉤部材が、本体枠に取り付けられた受け金具に係合することで施錠され、前記取付板に取り付けられたシリンダ錠の解錠操作によって、前記引張バネの付勢力に抗し前記施錠杆を支持板に沿って摺動させて、前記鉤部材を施錠位置から解錠位置に回動させ、前記鉤部材と前記受け金具との係合を解除することで解錠を行う遊技機の施錠装置であって、前記鉤部材の一側縁に前記受け金具を受け入れる切欠が設けられ、該切欠により前記鉤部材の先端側に鉤爪部が形成され、該鉤爪部の前記切欠側が前記支軸の軸心を中心とする円弧形状の係合用縁となっており、前記鉤部材の施錠位置における前記鉤部材の係合用縁と前記施錠杆の摺動方向と平行な接線との接点が、前記施錠杆の摺動方向と直交し前記支軸の軸心を通る直線上に位置するように設定され、前記施錠杆または前記鉤部材のいずれか一方にプレスによるダボ出し加工またはバーリング加工によって形成された突起が、他方に穿設された長孔に係合することで、前記施錠杆の摺動に連動して前記鉤部材が施錠位置と解錠位置との間で回動可能となっていることを特徴とする。
【００１５】
これによれば、鉤部材は、受け金具を受け入れるサイズの切欠を備え、その切欠側の受け金具と係合する係合用縁が円弧形状となっていることから、受け金具との係合用縁との間にガタとなる間隙を生ずるように設定しなくても、高々係合用縁と受け金具との間で僅かな摩擦力が発生する程度で、鉤部材は支軸を中心に円滑に回動することになり、確実に施錠することができ、また、解錠も円滑に行うことができる。
【００１６】
すなわち、前面枠を本体枠に対し閉鎖すると、鉤爪部が受け金具に当接し、引張バネの付勢力に抗し、支軸の軸心を中心に回動し、鉤部材の鉤爪部の先端が受け金具を乗り越えると、引張バネの復元力によって鉤部材が施錠位置に復帰して、受け金具が鉤部材と係合し、施錠状態となる。
施錠状態において、シリンダ錠の解錠操作を行うと、引張バネの付勢力に抗し施錠杆が支持板に沿って摺動し、該摺動に連動して鉤部材が支軸の軸心を中心に回動し、鉤部材が施錠位置から解錠位置になり、鉤部材と受け金具との係合が外れて解錠され、前面枠を本体枠に対し開くことができる。
【００１７】
そして、施錠状態において、蝶番を支点として前面枠を不正に水平方向にこじ開けようとする力が働いても、その力は、前記施錠杆の摺動方向と直交し前記支軸の軸心を通る直線に沿って働くことから、鉤部材が支軸を中心に解錠する方向に回動する恐れはなく、また、前面枠と本体枠との間に不正操作を行うことのできる間隙等が生ずることがない。
仮に、施錠状態における鉤部材の係合用縁と受け金具との間に取り付け誤差等を勘案して間隙（ガタ）を設けるとしても、その間隙（ガタ）は、図１６に示すような従来の板状の受け金具に対応した施錠装置と比べ、わずかで良く、そのため、前面枠と本体枠との間に不正操作を行うことのできる程の間隙等が生ずることがない。
【００１８】
そして、前記鉤部材の係合用縁と前記施錠杆の摺動方向と平行な接線との接点が、円柱状受け金具との係合当接点となっていてもよい。
【００１９】
また、前記施錠杆または前記鉤部材のいずれか一方にプレスによるダボ出し加工またはバーリング加工によって形成された突起が、他方に穿設された長孔に係合することで、前記施錠杆の摺動に連動して前記鉤部材が施錠位置と解錠位置との間で回動可能となっている。これにり、前記突起を、他方に穿設された長孔に係合させることで、施錠杆の摺動に連動して、鉤部材を回動させることが可能となり、従来の施錠装置のように、鉤部材と施錠杆とを連結ピンでかしめて連結する工程が必要なく、製造コストを低減することができる。また、従来の施錠装置のような支持板に連結ピンのかしめ部の逃がし用の湾曲長孔を穿設する必要がないことから、この点からも製造コストを低減することにもなる。また、従来の施錠装置においては、鉤部材の回動を可能とする支軸の軸線と、鉤部材と施錠杆を連結する連結ピンの軸線とが平行になっていないと、鉤部材の回動、および／または施錠杆の摺動に無理な力を必要としたり、きしんだりすることから、鉤部材と受け金具との係合が円滑、確実に行われなかったり、係合状態が不十分であったり、キー操作による解錠が円滑、容易に行い難いといった欠点があったが、この施錠装置では、かかる欠点がなく、施錠・解錠が円滑で確実であり、しかも、容易に行うことができることになる。
【００２０】
また、縦長の取付板の側方に支持板が起立した基枠体の内側に、施錠杆が前記支持板に沿って上下に摺動可能に配設され、該施錠杆が引張バネにより施錠方向に付勢され、前記取付板が本体枠に対し開閉可能とされた前面枠に取り付けられ、前記支持板の上部と下部に設けられた支軸を中心に軸支され、前記施錠杆の摺動に連動して施錠位置と解錠位置との間で回動可能な鉤部材が、本体枠に取り付けられた受け金具に係合することで施錠され、前記取付板に取り付けられたシリンダ錠の解錠操作によって、前記引張バネの付勢力に抗し前記施錠杆を支持板に沿って摺動させて、前記鉤部材を施錠位置から解錠位置に回動させ、前記鉤部材と前記受け金具との係合を解除することで解錠を行う遊技機の施錠装置であって、前記施錠杆または前記鉤部材のいずれか一方にプレスによるダボ出し加工またはバーリング加工によって形成された突起が、他方に穿設された長孔に係合することで、前記施錠杆の摺動に連動して前記鉤部材が施錠位置と解錠位置との間で回動可能となっていてもよい。
【００２１】
これによれば、施錠杆または前記鉤部材のいずれか一方に形成された前記突起を、他方に穿設された長孔に係合させることで、施錠杆の摺動に連動して、鉤部材を回動させることが可能となり、従来の施錠装置のように、鉤部材と施錠杆とを連結ピンでかしめて連結する工程が必要なく、製造コストを低減することができる。また、従来の施錠装置のような支持板に連結ピンのかしめ部の逃がし用の湾曲長孔を穿設する必要がないことから、この点からも製造コストを低減することにもなる。
【００２２】
また、従来の施錠装置においては、鉤部材の回動を可能とする支軸の軸線と、鉤部材と施錠杆を連結する連結ピンの軸線とが平行になっていないと、鉤部材の回動、および／または施錠杆の摺動に無理な力を必要としたり、きしんだりすることから、鉤部材と受け金具との係合が円滑、確実に行われなかったり、係合状態が不十分であったり、キー操作による解錠が円滑、容易に行い難いといった欠点があったが、この施錠装置では、かかる欠点がなく、施錠・解錠が円滑で確実であり、しかも、容易に行うことができる。
【００２３】
【発明の実施の形態】
以下、図面に基づきこの発明の態様を更に詳細に説明する。もちろんこの発明は以下の態様によって限定されるものではない。
図１は、この発明の遊技機の施錠装置の１態様を示す左側面図、図２は背面図を示す。
ここにおいて、施錠装置は、パチスロ機に使用されるものとして図示されている。
【００２４】
図１および図２から明らかなように、施錠装置１は、縦長の取付板２の側方に支持板３が起立した断面Ｌ字状の基枠体４の内側において、施錠杆５が支持板３に沿って上下に摺動可能に配設され、後述するような係合構造によって施錠杆５の摺動に連動して、支持板３の上部と下部に設けられた支軸６、６を中心に軸支された鉤部材７、７が、施錠位置と解錠位置との間で回動可能とされており（図１の矢印方向参照）、また、施錠杆５と支持板３の間にリセット作動杆８が上下に摺動可能に配設されている。
【００２５】
施錠杆５の摺動に連動して、支持板３の上部と下部に設けられた支軸６、６を中心に軸支された鉤部材７、７が、施錠位置と解錠位置との間で回動可能とされる構造は、施錠装置１の上部と下部とで機構的に同一であることから、施錠装置１の上部について図示して説明し、下部における同一の構造については説明を省略する。図３は施錠装置の上方部の部分拡大左側面図であり、鉤部材７が施錠位置にある状態であって、施錠杆５が上下方向（図ではＸ方向で示す）に摺動するものとして示されている。図４は、図３におけるＡ−Ａ線断面図である。
【００２６】
図３に示されるように、鉤部材７は、板状であって、その下側縁に湾曲状の切欠７ａが設けられ、その先端側に受け金具と係合する下向きの鉤爪部７ｂが形成されている。前記切欠７ａは、後述する受け金具１４を受け入れる大きさ（深さ、幅）を有し、鉤爪部７ｂの切欠側は支軸６の軸心Ｏを中心とする半径Ｒの円弧形状の係合用縁７ｃとなっており、鉤部材７の施錠位置における係合用縁７ｃの施錠杆５の摺動方向Ｘと平行な接線との接点が、施錠杆５の摺動方向Ｘと直交し支軸６の軸心Ｏを通る直線Ｙ上に位置するように設定されている。
鉤爪部７ｂの外側縁７ｄは、後述するように、施錠時に受け金具と当接し、鉤部材７を支軸６を中心に上方に回動させるため爪先に向かって傾斜した円弧状となっている。
【００２７】
鉤部材７の基部７ｅの支軸の挿通孔よりも取付板寄りの位置に穿設された長孔１０に、施錠杆５に形成された鉤部材側に突出する突起１１を係合させることで、施錠杆５の上下への摺動に連動し、鉤部材７が支軸６を中心に施錠位置と解錠位置との間で回動できるようになっている。
施錠杆５に形成した突起１１の突出量は、鉤部材７の厚さを越えないものとなっている。このような突起１１は、例えば、プレスによるダボ出し加工によって形成することができる。
【００２８】
そして、支持板３の後縁の上部と下部には、受け金具１４を受け入れる凹部３ａ、３ａがそれぞれ形成されており、下部の凹部３ａの下方位置には、湾曲した当接案内面を有するプラスチック製の当接部材１３が取り付けられている（図１参照）。
【００２９】
施錠装置１の鉤部材７と係合する受け金具１４は、図５の左側面図、図６の正面図に示す構造のものである。
図５、図６に示すように、受け金具１４、１４は、円柱状のピンで、基板１５の上下部に固定されている。受け金具１４、１４の基板１５への固定位置は、施錠装置１の鉤部材７が施錠位置にある状態において、鉤部材７の切欠７ａが受け金具１４を受け入れ、係合して施錠できる位置に設定されている。基板１５の下方の受け金具１４の下方位置には、前述した支持板３に取り付けられたプラスチック製の当接部材１３を受け止める受部材１６が取り付けられている。該受部材１６の前方側は、平坦部に続く傾斜面部となっている。
基板１５には、パチスロ機の本体枠に取り付けるための複数の止めネジ挿通孔１５ａが穿設されている。
【００３０】
図１、図２に示されるように、施錠杆５とリセット作動杆８の摺動は、後述するようにシリンダ錠１７のキー操作によって行われるようになっている。
支持板３に設けられた支軸６、６は、円柱状のピンが使用されており、支持板３の上下への摺動をガイドする機能も兼用するものである。支持板３の上下部に設けられた支軸６、６と中間部に設けられたピン１８が、施錠杆５の上下端部および中間部に穿設された長孔１９、１９、１９に挿通され、例えば、ピン１８が長孔１９の下端縁に当接する位置と上端縁に当接する位置との間で施錠杆５が上下に摺動することになる。
【００３１】
リセット作動杆８の上部に穿設された長孔２１には、前記中間部のピン１８が挿通されるとともに、リセット作動杆８の下部にはリセット作動片２２が設けられて、施錠杆５に穿設されたスリット２３を通り内側に突出しており、リセット作動杆８が上下に摺動できるようになっている。リセット作動片２２は、右方に直角に折り曲げられ（図１参照）、その先端が取付板２の近傍にまで達しており、リセット作動杆８の上方への摺動により図示していないリセットスイッチを作動させるようになっている。このリセットスイッチは、リセット作動片２２の有無を検出して、パチスロ機のリセット信号を出力するもので、リミットスイッチ等の接触スイッチが使用されるが、これに限られず、光電スイッチ等の非接触スイッチであってもよい。
【００３２】
リセット作動杆８の長孔２１の下方位置にはバネ掛止部２４が設けられ、施錠杆５のスリット２５を通って基枠体４の内側に突出している。該バネ掛止部２４には、引張バネ２６の一端が係止され、該引張バネ２６の他端は、施錠杆５に設けられたバネ掛止部２７に掛止されており、引張バネ２６によって、施錠杆５は上方に付勢され、リセット作動杆８は下方に付勢される。
【００３３】
取付板２の下方部は、幅広部２ａとされ、該幅広部２ａに穿設された孔にシリンダ錠１７が内側から挿入されて外側に突出し、シリンダ錠１７のフランジ部２９を介してネジ止めされている。シリンダ錠１７の錠軸３０は基枠体４の内側に突出し、該錠軸３０には、第１突部３１ａと第２突部３１ｂを備えたカム板３１が固定されている。第１突部３１ａは、シリンダ錠１７のキー操作によってカム板３１を図２の反時計方向に回動させたときに、施錠杆５の係合孔３２の下辺に係合して、施錠杆５を下方に摺動させる機能を果たし、第２突部３１ｂは、シリンダ錠１７のキー操作によってカム板３１を図２の時計方向に回動させたときに施錠杆５の逃がし窓３３を通って、リセット作動杆８の係合孔３４の上辺に係合して、リセット作動杆８を上方に摺動させる機能を果たすようになっている。
【００３４】
取付板２には、複数の止めネジ挿通孔２ｂが穿設されており、施錠装置１が止めネジでパチスロ機の前面枠の自由端の背面に取り付けられるようになっている。
【００３５】
図７に、パチスロ機の前面枠３７の自由端の背面に、上記のような構造の施錠装置１を取付板２の止めネジ挿通孔２ｂを利用してネジ（図示せず）で固定し、一方、受け金具１４、１４を、施錠状態において施錠装置１の鉤部材７、７と係合する位置に位置決めして、基板１５の止めネジ挿通孔１５ａを利用して本体枠３８にネジ（図示せず）で固定した状態を示す。図７においては、前面枠３７が、本体枠３８に対し図示していない蝶番を支点として、解放された状態を示している。
この状態における施錠装置１は、引張バネ２６の付勢力により、施錠杆５が上方位置にあって鉤部材７は施錠位置となっており、リセット作動杆８は下方位置にある。
【００３６】
そして、前面枠３７は、取り付けられている各種機器等の重量が加わることで自由端側が若干下がった状態にある。図示していない蝶番を支点にして前面枠３７を本体枠３８に対して閉鎖すると、先ず、施錠装置１の当接部材１３が、受部材１６に乗り上がり、前面枠３７の自由端側が上方に持ち上げられ、施錠装置１の鉤部材７と受け金具１４とが施錠に適した位置関係に調節される。次いで、鉤爪部７ｂの外側縁７ｄが受け金具１４に当接すると、鉤部材７は、引張バネ２６の付勢力に抗し、図８（ａ）に示すように支軸６の軸心Ｏを中心に上方に回動する。そして、鉤部材７の鉤爪部７ｂの下端が受け金具１４を乗り越えると、引張バネ２６の復元力によって鉤部材７が下方に回動し施錠位置に復帰することで、受け金具１４に鉤部材７が係合するとともに、支持板３の凹部３ａに受け金具１４が収まった図８（ｂ）に示す施錠状態となる。
【００３７】
図８（ｂ）の施錠状態からも明らかなように、鉤部材７の切欠７ａは、受け金具１４を受け入れる大きさ（深さ、幅）を有し、鉤爪部７ｂの切欠側は支軸６の軸心Ｏを中心とする半径Ｒの円弧形状の係合用縁７ｃとなっており、受け金具１４の半径ｒは、係合用縁７ｃの半径Ｒよりも小さいものとなっている。これにより、施錠状態における鉤部材７の係合用縁７ｃと受け金具１４との間に間隙（ガタ）が生じるようになっていなくても、前記したように、施錠時に上方に回動した鉤部材７の鉤爪部７ｂの先端が、受け金具１４を乗り越え、次いで、鉤部材７が、引張バネ２６の復元力によって施錠位置に復帰しようとする際、受け金具１４と係合用縁７ｃとは点接触による摩擦を生ずるに過ぎないことから、発生する摩擦力は僅かであり、施錠位置に戻らず途中に引っかかったりすることがなく、鉤部材７の円弧形状の係合用縁７ｃが受け金具１４の表面を滑りながら、その施錠位置にまで円滑に戻り、確実に施錠することができることになる。なお、解錠も同様に円滑に行うことができることはいうまでもない。
【００３８】
そして、施錠状態においては、支軸６の軸心Ｏ、受け金具１４の軸心Ｑ、および、鉤部材７の係合用縁７ｃと施錠杆５の摺動方向Ｘと平行な接線との接点Ｐは、直線Ｙ上に位置することになり、切欠７ａの深い係合位置で受け金具１４を係合することができ、確実な施錠状態を確保できる。前記接点Ｐは、鉤部材７の円弧形状の係合用縁７ｃが受け金具１４に外接する当接点ともなる。
【００３９】
この施錠状態において、蝶番を支点として前面枠３７を水平方向にこじ開けようとしても、受け金具１４は鉤部材７の円弧形状の係合用縁７ｃと前記接点Ｐで当接しており、力は直線Ｙ方向（水平方向）に作用するだけであって、鉤部材７が支軸６を中心に解錠する方向に回動する恐れはなく、また、前面枠３７と本体枠３８との間に不正操作を行うことのできる間隙等が生ずることがない。
この施錠装置１に対応した受け金具１４は、従来のような板状の受け金具と比べ、頑丈であり、前面枠３７をこじ開けようとする大きな力にも耐えうることから、安全で、確実な施錠をすることができる。
そして、従来のような板状の受け金具のように、ペンチ等で鉤部材との係合状態を調節する必要が無い等大きな利点が得られる。
【００４０】
仮に、施錠状態における鉤部材７の係合用縁７ｃと受け金具１４との間に取り付け誤差等を勘案して間隙（ガタ）を設けるとしても、その間隙（ガタ）は、図１６に示すような従来の板状の受け金具に対応した施錠装置と比べ、わずかで良く、そのため、前面枠３７と本体枠３８との間に不正操作を行うことのできる程の間隙等が生ずることがない。
【００４１】
また、仮に、図９に示すように、支軸６の軸心Ｏから鉤部材７の円弧形状の係合用縁７ｃまでの半径Ｒに比べ、支軸６の軸心Ｏから受け金具１４の軸心Ｑまでの距離Ｌと、受け金具１４の半径ｒとの和（Ｌ＋ｒ）の方が僅かでも大きい場合は、施錠状態とならないことから、容易に施錠装置１または受け金具１４の取り付けミスを発見でき、パチスロ機の施錠不良を見過ごす恐れがない。
【００４２】
また、この施錠装置１は、施錠杆５の摺動に連動して鉤部材７を回動させるため、組立において、施錠杆５に形成した突起１１を鉤部材７の基部７ｅの長孔１０に挿入し、突起１１を長孔１０に係合させるとともに、施錠杆５の上下端部の長孔１９と鉤部材７の支軸６を挿通する挿通孔（図示せず）とを合致させ、支軸６を施錠杆の長孔１９、鉤部材７の支軸６の挿通孔に挿通し、支持板３に固定すればよい。これによって、従来の施錠装置のように、鉤部材と施錠杆とを連結ピンでかしめて連結する工程が必要なくなり、製造コストを抑えることができる。
【００４３】
また、従来の施錠装置においては、鉤部材の回動を可能とする支軸の軸線と、鉤部材と施錠杆を連結する連結ピンの軸線とが平行になっていないと、鉤部材の回動、および／または施錠杆の摺動に無理な力を必要としたり、きしんだりすることから、鉤部材と受け金具との係合が円滑、確実に行われなかったり、係合状態が不十分であったり、キー操作による解錠が円滑、容易に行い難いといった欠点があったが、この施錠装置では、かかる欠点がなく、施錠・解錠が円滑で確実であり、しかも、容易に行うことができる。
【００４４】
また、前面枠３７が本体枠３８に対し閉鎖された施錠状態では、支持板３の凹部３ａ、３ａに受け金具１４、１４が収まっていることから、前面枠３７を無理に持ち上げて、鉤部材７、７と受け金具１４、１４との係合を外そうとしても、凹部３ａ、３ａの下縁が受け金具１４、１４に当接して持ち上げることができない。
【００４５】
前記施錠状態において、キー（図示せず）をシリンダ錠１７に差し込み、キー操作によりカム板３１を図２における反時計方向に回動させると、カム板３１の第１突部３１ａが、施錠杆５の係合孔３２の下辺に係合し、施錠杆５が引張バネ２６の付勢力に抗し下方に摺動することで、鉤部材７の基部７ｅの長孔１０に挿入された突起１１によって、鉤部材７が支軸６の軸心Ｏを中心として上方に回動し、鉤部材７、７と受け金具１４、１４との係合が外れ解錠される。
そこで、蝶番を支点にして前面枠３７を開放方向に回動させると、当接部材１３が、受部材１６を下り、蝶番を支点に前面枠３７を本体枠３８に対し開くことができる。
このキー操作を終了させると、施錠杆５は引張バネ２６の付勢力により、図１で示した位置に戻る。
【００４６】
また、施錠状態において、キーをシリンダ錠１７に差し込み、カム板３１を図２の時計方向に回動させると、カム板３１の第２突部がリセット作動杆８の係合孔３４の上辺に係合し、リセット作動杆８が引張バネ２６の付勢力に抗し上方に摺動することで、リセット作動片２２によって図示していないリセットスイッチを作動させ、リセット信号を出力させる。該リセット信号によってパチスロ機のリセットが行われる。キー操作によるリセット操作を解除すると、リセット作動杆８は引張バネ２６の付勢力により、図２に示す初期位置に戻る。
受け金具１４は、円柱状のピンとしているが、これに限られず、例えば、図１０に示すように六角柱状のピン３９であってもよく、また、図１１に示すように楕円柱状のピン４０であってもよく、各種の断面形状のピンが採用可能である。
【００４７】
施錠装置としては、前記した構造に限定されるものではなく、各種の態様が採用可能であり、例えば、以下のように変更された構造のものであってもよい。以下においては、前述した施錠装置との主な相違点についてのみ説明し、その他の点については詳細な説明は省略する。
【００４８】
図１２に示す施錠装置４１は、鉤部材４２の基部４２ａの取付板寄りの位置において、支軸４３を中心に回動可能とされ、基部４２ａの切欠寄りの位置に穿設された長孔４４に、施錠杆４５に形成された支持板側に突出する突起４６が挿入され、突起４６と長孔４４との係合によって、施錠杆４５の摺動に連動し、鉤部材４２が支軸４３を中心に施錠位置と解錠位置との間で回動できるようになっているものである。この構造においては、施錠杆４５を上方に移動させることで解錠できることから、カム板を時計方向に回動させたときに、施錠杆の係合孔に下方から係合して、施錠杆を上方に摺動させるようにする等適宜の変更を行えばよい。
【００４９】
なお、図１３に示す施錠装置５１は参考例であって、鈎部材５２の基部５２ａの取付板２寄りの位置において、鉤部材５２を施錠杆５３と連結ピン５４で連結し、施錠杆５３の上下への摺動に連動し、鉤部材５２が支軸５５を中心に施錠位置と解錠位置との間で回動できるようにしたものである。図１３においては、鉤部材５２には、連結ピン５４を挿通する孔は長孔としている。
【００５０】
また、図示していないが、鉤部材には、受け金具との当接を確実にするため、鉤部材の鉤爪部の外側縁を折り曲げ、受け金具との当接面を形成したものであってもよい。
【００５１】
以上においては、施錠杆に鉤部材側へ突出する突起を設け、鉤部材に該突起と係合する長孔を穿設したものとして示したが、これに限られず、鉤部材に施錠杆側へ突出する突起を設け、施錠杆に該突起と係合する長孔を穿設することで、施錠杆の上下への摺動に連動し、鉤部材が支軸を中心に施錠位置と解錠位置との間で回動できるようにしてもよいことはいうまでもない。そして、突起は、プレスによるダボ出し加工によるものだけでなく、バーリング加工によって形成したもの等であってもよい。
【００５２】
図１４は、鉤部材６１に施錠杆側へ突出する突起６２を設け、施錠杆６３に該突起６２と係合する長孔６４を穿設することで、施錠杆６３の上下への摺動に連動し、鉤部材６１が支軸６５を中心に施錠位置と解錠位置との間で回動できるようにした施錠装置６６である。
鉤部材６１に設けられた突起６２は、図１５に示すようにバーリング加工によって形成されたものとして示されている。そして、この施錠装置６６においては、鉤部材６１に穿設した支軸の挿通孔の周囲に、例えば、エンボシング加工による支持板側へ僅かな浮き出し６１ａが形成され、支持板３との接触面積が少なくなるようになっている。
その他、図１に示す施錠装置と同一の構成については、同一の番号を付し、説明を省略する。
【００５３】
施錠装置としては、パチスロ機に適したものとして説明したが、これに限られず、リセット作動杆に代えパチンコ機用のガラス枠解錠操作杆を採用することで、パチンコ機に適した施錠装置とすることができる。
【００５４】
【発明の効果】
この発明は、以上詳しく説明したように構成されているので、以下に記載されるような効果を奏する。
すなわち、遊技機の施錠装置において、鉤部材の一側縁に受け金具を受け入れる切欠が設けられ、該切欠により前記鉤部材の先端側に鉤爪部が形成され、該鉤爪部の前記切欠側が前記支軸の軸心を中心とする円弧形状の係合用縁となっており、前記鉤部材の施錠位置における前記鉤部材の係合用縁と前記施錠杆の摺動方向と平行な接線との接点が、前記施錠杆の摺動方向と直交し前記支軸の軸心を通る直線上に位置するように設定されていることにより、鉤部材は、受け金具を受け入れるサイズの切欠を備え、その切欠側の受け金具と係合する係合用縁が円弧形状となっており、受け金具との係合用縁との間に間隙を生ずるように設定しなくても、高々係合用縁と受け金具との間で僅かな摩擦力が発生する程度で、鉤部材は支軸を中心に円滑に回動することになり、確実に施錠することができるし、また、解錠も同様に円滑に行うことができる。
また、遊技機の施錠装置において、施錠杆または前記鉤部材のいずれか一方にプレスによるダボ出し加工またはバーリング加工によって形成された突起が、他方に穿設された長孔に係合することで、前記施錠杆の摺動に連動して前記鉤部材が施錠位置と解錠位置との間で回動可能となっていることにより、施錠杆または鉤部材のいずれか一方に形成された前記突起を、他方に穿設された長孔に係合させることで、施錠杆の摺動に連動して、鉤部材を回動させることが可能となり、従来の施錠装置のように、鉤部材と施錠杆とを連結ピンでかしめて連結する工程が必要なく、製造コストを低減することができる。また、従来の施錠装置のような支持板に連結ピンのかしめ部の逃がし用の湾曲長孔を穿設する必要がないことから、この点からも製造コストを低減することにもなる。また、従来の施錠装置においては、鉤部材の回動を可能とする支軸の軸線と、鉤部材と施錠杆を連結する連結ピンの軸線とが平行になっていないと、鉤部材の回動、および／または施錠杆の摺動に無理な力を必要としたり、きしんだりすることから、鉤部材と受け金具との係合が円滑、確実に行われなかったり、係合状態が不十分であったり、キー操作による解錠が円滑、容易に行い難いといった欠点があったが、この施錠装置では、かかる欠点がなく、施錠・解錠が円滑で確実であり、しかも、容易に行うことができる。
なお、本発明のその他の作用・効果については、実施の形態および図面からも明らかである。

BACKGROUND OF THE INVENTION
The present invention relates to a locking device that locks a front frame of a gaming machine to a main body frame. More specifically, the present invention relates to a locking device suitable for locking and unlocking a front frame of a gaming machine exemplified by a pachinko machine, a pachislot machine, a slot machine, a smart ball, an arrange ball, etc. It is about.
[0002]
[Prior art]
The front frame of the gaming machine is hinged at one end and fixed to the main frame, and the other end is a free end that can be rotated with respect to the main frame. The locking device which enables locking with the received metal fitting is attached.
[0003]
Conventionally, for example, a locking device having a structure as described in Registered Utility Model No. 2508452 is known, which is shown in FIG. FIG. 16 also shows a receiving metal fitting, a front frame, and a main body frame. The locking device 70 is roughly disposed inside a base frame 73 in which a support plate 72 stands on the side of a vertically long mounting plate 71, and a locking rod 74 is slidable up and down along the support plate 72. The locking rod 74 is urged in the locking direction by a tension spring 75, and the flange members 77 and 77 are pivotally supported around pivots 76 and 76 provided on the upper and lower portions of the support plate 72. The upper and lower ends of the locking rod 74 are connected by connecting pins 78 and 78, respectively, and a cylinder lock 79 is attached to the intermediate portion of the mounting plate 71.
The guide pin 80 is inserted into the long hole 81 formed in the locking rod 74 and fixed to the support plate 72, and the locking rod 74 is guided by the guide pin 80, so that the locking rod 74 is supported by the support plate 72. It slides up and down along.
[0004]
In the gaming machine provided with such a locking device, when the front frame 82 is closed with respect to the main body frame 83 with a hinge (not shown) as a fulcrum, the hook member 77 is attached to the metal fitting 84 provided on the main body frame 83. Comes into contact with each other, and the collar member 77 rotates upward, and the locking collar 74 slides downward. When the tip of the claw portion 77a of the collar member 77 gets over the upper end edge of the catch metal 84, the locking collar 74 returns to the locked position by the restoring force of the tension spring 75, and the collar member 77 engages with the catch metal 84, The front frame 82 is locked to the main body frame 83. Then, a key (not shown) is inserted into the cylinder lock 79, the cam plate 87 is rotated in the unlocking direction by the key operation, the locking rod 74 is slid downward, and the rod member 77 is rotated upward. The front frame can be opened with the hinge 84 as a fulcrum by releasing the engagement between the catch 84 and the flange member 77.
[0005]
The engagement relationship between the collar member 77 of the locking device 70 and the metal fitting 84 will be described in more detail.
Here, since the engagement relationship between the upper and lower flange members 77 and 77 and the receiving metal pieces 84 and 84 is the same, the description will be made based on the upper flange member and the receiving metal part, and the lower hook member and the receiving metal part will be described. Is omitted. FIG. 17 is a partially enlarged explanatory view showing a relational structure between the upper part of the locking device and the receiving metal fitting. For convenience, the main body frame and the front frame are not shown. As shown in FIG. 17, the collar member 77 is provided with a substantially trapezoidal cutout 77b at the lower edge thereof, and a claw portion 77a is formed on the distal end side of the collar member 77 by the cutout 77b, and the claw portion 77a. The notch side is a linear engaging edge 77c, and the engaging edge 77c of the hook member 77 in the locking position is parallel to the sliding direction X of the locking bar (that is, the sliding direction X of the locking bar). Is perpendicular to the straight line Y passing through the axis of the support shaft 76. The depth of the notch 77b, that is, the bottom edge 77d of the notch 77b extends beyond the straight line Y.
[0006]
The receiving bracket 84 is plate-shaped, and in the locked state, as shown in FIG. 17, the upper end edge of the receiving bracket 84 contacts the bottom edge 77d of the notch 77b of the flange member 77 or reaches the vicinity of the bottom edge 77d. Thus, the receiving metal 84 and the engaging edge 77c of the flange member 77 are engaged, and in the locked state, it resists a force for forcibly opening the front frame.
[0007]
In order to lock the hook member 77 by engaging with the receiving metal member 84, or to release the engagement with the receiving metal member 84 and unlock it, the hook member 77 is indicated by a solid line and a two-dot chain line in FIG. That is, it is necessary to provide a gap t that allows the hook member 77 to rotate about the support shaft 76 between the metal fitting 84 and the hook claw portion 77a in the locked state.
On the other hand, the gap t functions as a backlash between the main body frame and the front frame, and depending on the size of the backlash, for example, a thin steel plate with a hook formed at the tip or a hook is formed by bending the tip. When an operating tool such as a piano wire is inserted from between the backlashes, the tip of the hook is pulled by the hook member 77 and pulled, and the hook member 77 is rotated about the support shaft 76 in the unlocking direction. 84 and the hook member 77 can be disengaged, and the front frame 82 can be opened with the hinge as a fulcrum. In this way, when the front frame 82 is opened, it becomes possible to operate the devices and parts disposed on the back surface of the front frame 82, modify these devices and parts, and control the winning rate of the gaming machine. Unauthorized operations such as replacing the ROM with a high-winning back ROM are possible. Since the gap t needs to be increased as the depth to the bottom edge 77d of the notch 77b of the flange member 77 is increased, the backlash is also increased.
[0008]
Then, the mounting bracket 84 is attached to the main body frame so that the backlash is forcibly less than the required backlash, or the locking device 70 is mounted on the front frame or the mounting bracket 84 is mounted on the main body frame by an error. When the gap t between the catch 84 and the claw portion 77a becomes insufficient, an incomplete locking state as shown in FIG. 18 occurs, and in this state, a force for forcibly opening the front frame works. Then, the engagement point between the flange member 77 and the receiving metal member 84 gradually shifts, and the flange member 77 rotates about the support shaft 76 in the unlocking direction, and the engagement is released even with a relatively small force. Will open.
[0009]
Therefore, when assembling a gaming machine or the like, assuming that the gap t between the receiving bracket 84 and the flange member 77 at the time of locking is insufficient or excessive, the receiving gap can be adjusted to an appropriate gap t. The thickness of the metal fitting 84 is set such that it can be bent with pliers or the like. However, when it is necessary to adjust the gap t by bending the receiving bracket 84 with pliers or the like, the relationship between the receiving bracket 84 and the flange member 77 is directly obstructed by the front frame when the front frame is closed. I can't confirm. The adjustment of the gap t is performed by opening the front frame. However, it is necessary to rely on the can, and it tends to be inaccurate, and it is necessary to repeat the adjustment until the proper gap t is reached. Costs and leads to high costs.
[0010]
In addition, as described above, since the metal fitting is thick enough to be bent with a tool such as pliers, it is difficult to say that the strength is sufficient, and in the locked state, the front frame is used for an illegal operation or the like. If it is forcibly opened, the bracket will be deformed relatively easily, and the front frame will be opened.
[0011]
As shown in FIG. 19, when the depth of the notch 77 b of the flange member 77 is made shallow, the depth is up to a straight line Y that is perpendicular to the sliding direction X of the locking rod 74 and passes through the axis of the support shaft 76. Even if the gap t (that is, backlash) as shown in FIG. 9 is not provided between the receiving metal 84 and the hook claw 77a, the hook 77 is engaged with the receiving metal 84 as shown by the solid line and the two-dot chain line in FIG. Thus, it can be locked, or it can be unlocked by releasing the engagement with the receiving metal 84. However, since the notch 77b of the flange member 77 is shallow, the engagement with the receiving metal fitting 84 in the locked state tends to be insufficient. As shown in FIG. 20, if the front end of the claw portion 77a is extended downward, the engagement between the receiving member 84 and the collar member 77 in the locked state is sufficient, but the collar member 77 becomes large and the cost increases.
[0012]
By the way, as shown in FIG. 21, the conventional locking device 70 has a structure so that the hook member 77 connected to the locking hook 74 does not interfere with the rotation about the axis of the support shaft 76. In addition, the support plate 72 is required to be provided with a curved elongated hole 90 for releasing the caulking portion of the connecting pin 78, and in the assembly of the locking device 70, the shaft hole 91 of the flange member 77 is formed in the shaft hole 91. It is necessary to insert the support shaft 76, and to fix the support shaft 76 to the support plate 72, and to connect the flange member 77 and the locking rod 74 with the connection pin 78. Requires a process. In such a structure, if the axis of the support shaft 76 that allows the collar member 77 to rotate and the axis of the connecting pin 78 that couples the collar member 77 and the locking collar 74 are not parallel, Since excessive force is required for the rotation of the member 77 and / or the sliding of the locking rod 74, and the engagement between the rod member 77 and the receiving metal 84 is not smoothly performed. It has been pointed out that the combined state is insufficient and it is difficult to perform unlocking smoothly by key operation.
[0013]
[Problems to be solved by the invention]
The invention of this application was devised as a result of diligent research in view of the above-described circumstances, and is a game machine that can be locked and unlocked with a metal fitting smoothly and reliably and that can be easily performed. Provided is a locking device, in particular, a locking device for a gaming machine in which locking or unlocking with a receiving metal fitting is smooth and reliable, and in addition to being easily performed, can also prevent unauthorized operation such as unauthorized unlocking. For the purpose.
[0014]
[Means for Solving the Problems]
  In order to solve the above problems, the present invention is arranged inside the base frame body in which the support plate stands on the side of the vertically long mounting plate, and the locking rod is slidable up and down along the support plate. The locking rod is urged in the locking direction by a tension spring, the mounting plate is attached to a front frame that can be opened and closed with respect to the main body frame, and is pivoted about support shafts provided at the upper and lower portions of the support plate. A hook member that is supported and rotatable between a locking position and an unlocking position in conjunction with the sliding movement of the locking hook is locked by engaging a receiving metal fitting attached to the main body frame, and the mounting By unlocking the cylinder lock attached to the plate, the locking rod is slid along the support plate against the urging force of the tension spring, and the rod member is rotated from the locking position to the unlocking position. The locking device of the gaming machine that unlocks by releasing the engagement between the bar member and the metal fitting A notch for receiving the metal fitting is provided on one side edge of the hook member, and a notch portion is formed on the leading end side of the hook member by the notch, and the notch side of the hook member is an axis of the support shaft. An engagement edge having an arc shape centering on the center, and a contact point between the engagement edge of the collar member and a tangent parallel to the sliding direction of the locking collar at the locking position of the collar member is the locking collar. It is set to be on a straight line that is perpendicular to the sliding direction of the shaft and passes through the axis of the support shaft.A protrusion formed by doweling or burring by a press on either one of the locking bar or the bar member engages with a long hole drilled on the other side, so that the locking bar can slide. In conjunction with this, the collar member can rotate between the locked position and the unlocked position.It is characterized by.
[0015]
According to this, the flange member has a notch of a size for receiving the receiving metal fitting, and the engaging edge that engages with the receiving metal fitting on the notch side has an arc shape. Even if it is not set so as to generate a gap between them, the saddle member rotates smoothly around the support shaft so that a slight frictional force is generated between the engagement edge and the receiving metal. As a result, it can be reliably locked, and unlocking can be performed smoothly.
[0016]
That is, when the front frame is closed with respect to the main body frame, the claw portion comes into contact with the receiving metal, resists the biasing force of the tension spring, rotates around the axis of the support shaft, and the tip of the claw portion of the claw member When the bracket is moved over, the collar member is returned to the locked position by the restoring force of the tension spring, and the bracket is engaged with the collar member to be locked.
When the cylinder lock is unlocked in the locked state, the locking rod slides along the support plate against the urging force of the tension spring, and in conjunction with the sliding, the rod member moves the axis of the support shaft. Rotating to the center, the hook member is changed from the locked position to the unlocked position, the hook member is disengaged from the receiving metal and unlocked, and the front frame can be opened with respect to the main body frame.
[0017]
In the locked state, even if a force that attempts to open the front frame illegally horizontally with the hinge as a fulcrum acts, the force is perpendicular to the sliding direction of the locking rod and passes through the axis of the support shaft. Since it works along a straight line, there is no fear that the eaves member will rotate in the unlocking direction around the support shaft, and a gap or the like that allows unauthorized operation is generated between the front frame and the main body frame. There is nothing.
Even if a gap (gap) is provided between the engagement edge of the collar member in the locked state and the metal fitting in consideration of an attachment error or the like, the gap (gutter) is not a conventional plate as shown in FIG. Compared to a locking device corresponding to a metal receiving bracket, there is no need for a gap or the like to allow unauthorized operation between the front frame and the main body frame.
[0018]
A contact point between the engagement edge of the flange member and a tangent line parallel to the sliding direction of the locking rod may be an engagement contact point with the columnar bracket.
[0019]
  Also, either one of the locking ridge or the heel memberBy doweling or burring by pressingThe formed protrusion engages with the elongated hole formed in the other, so that the hook member can be rotated between the locked position and the unlocked position in conjunction with the sliding movement of the locked hook. HaveThe In this way, by engaging the projection with the long hole drilled on the other side, it becomes possible to rotate the collar member in conjunction with the sliding movement of the locking collar, like a conventional locking device. In addition, there is no need for a step of caulking and connecting the flange member and the locking rod with the connection pin, and the manufacturing cost can be reduced. Further, since it is not necessary to form a curved elongated hole for releasing the caulking portion of the connecting pin in the support plate as in the conventional locking device, the manufacturing cost is also reduced in this respect. Further, in the conventional locking device, if the axis of the support shaft that enables rotation of the eaves member and the axis of the connecting pin that connects the eaves member and the locking eaves are not parallel, the rotation of the eaves member , And / or an excessive force is required for the sliding of the locking rod or it is squeezed, so that the engagement between the flange member and the receiving metal fitting is not smoothly and reliably performed or the engagement state is insufficient. However, this locking device does not have such drawbacks, and the locking and unlocking is smooth and reliable, and can be easily performed. It will be possible.
[0020]
  A locking rod is slidable vertically along the supporting plate inside the base frame with the supporting plate standing on the side of the vertically long mounting plate, and the locking rod is locked in the locking direction by a tension spring. The mounting plate is attached to a front frame that can be opened and closed with respect to the main body frame, and is pivotally supported around pivots provided at the upper and lower portions of the support plate.

As will be described later, the outer edge 7d of the claw portion 7b is in an arc shape inclined toward the claw tip in order to abut against the receiving metal during locking and to turn the claw member 7 upward about the support shaft 6. .
[0027]
By engaging a projection 11 projecting toward the flange member formed in the locking rod 5 with a long hole 10 formed at a position closer to the mounting plate than the insertion hole of the support shaft of the base portion 7e of the flange member 7. In conjunction with the up-and-down sliding of the locking rod 5, the rod member 7 can rotate between the locking position and the unlocking position about the support shaft 6.
The protruding amount of the protrusion 11 formed on the locking bar 5 does not exceed the thickness of the bar member 7. Such a protrusion 11 can be formed by, for example, doweling by pressing.
[0028]
And the recessed part 3a, 3a which receives the receiving metal fitting 14 is each formed in the upper part and the lower part of the rear edge of the support plate 3, and the plastics which have the curved contact guide surface in the downward position of the lower recessed part 3a A contact member 13 made of metal is attached (see FIG. 1).
[0029]
The receiving metal fitting 14 engaged with the collar member 7 of the locking device 1 has a structure shown in the left side view of FIG. 5 and the front view of FIG.
As shown in FIGS. 5 and 6, the receiving brackets 14, 14 are fixed to the upper and lower portions of the substrate 15 with cylindrical pins. The fixing position of the catches 14 and 14 to the substrate 15 is a position where the notch 7a of the eaves member 7 can receive and engage with the eaves 14 in a state where the eaves member 7 of the locking device 1 is in the lock position. Is set. A receiving member 16 for receiving the plastic contact member 13 attached to the support plate 3 is attached to a position below the receiving metal fitting 14 below the substrate 15. The front side of the receiving member 16 is an inclined surface portion following the flat portion.
The substrate 15 has a plurality of set screw insertion holes 15a for attachment to the body frame of the pachislot machine.
[0030]
As shown in FIGS. 1 and 2, sliding of the locking rod 5 and the resetting operation rod 8 is performed by key operation of the cylinder lock 17 as will be described later.
The support shafts 6 and 6 provided on the support plate 3 use cylindrical pins, and also have a function of guiding the support plate 3 to slide up and down. The support shafts 6, 6 provided at the upper and lower portions of the support plate 3 and the pins 18 provided at the intermediate portion are inserted into the long holes 19, 19, 19 formed in the upper and lower end portions and the intermediate portion of the locking rod 5. For example, the locking rod 5 slides up and down between a position where the pin 18 contacts the lower end edge of the long hole 19 and a position where the pin 18 contacts the upper end edge.
[0031]
  The slot 21 formed in the upper part of the reset operation rod 8 has a pin in the intermediate portion.18Is inserted, and a reset operation piece 22 is provided at the lower portion of the reset operation rod 8 and protrudes inward through a slit 23 formed in the locking rod 5 so that the reset operation rod 8 slides up and down. It can be done. The reset operation piece 22 is bent to the right at a right angle (see FIG. 1), and the tip of the reset operation piece 22 reaches the vicinity of the mounting plate 2, and a reset switch (not shown) by sliding upward of the reset operation rod 8. Is to be activated. This reset switch detects the presence or absence of the reset operation piece 22 and outputs a reset signal of the pachislot machine. A contact switch such as a limit switch is used, but is not limited to this, and a non-contact such as a photoelectric switch. It may be a switch.
[0032]
A spring hooking portion 24 is provided at a position below the long hole 21 of the reset operating rod 8, and protrudes to the inside of the base frame body 4 through the slit 25 of the locking rod 5. One end of a tension spring 26 is locked to the spring latching portion 24, and the other end of the tension spring 26 is latched to a spring latching portion 27 provided on the locking rod 5. Thus, the locking rod 5 is biased upward, and the reset operating rod 8 is biased downward.
[0033]
The lower part of the mounting plate 2 is a wide part 2a. A cylinder lock 17 is inserted into a hole formed in the wide part 2a from the inside and protrudes outside, and is screwed through a flange part 29 of the cylinder lock 17 Has been. The lock shaft 30 of the cylinder lock 17 protrudes inside the base frame body 4, and a cam plate 31 having a first protrusion 31 a and a second protrusion 31 b is fixed to the lock shaft 30. The first protrusion 31a engages with the lower side of the engagement hole 32 of the locking rod 5 when the cam plate 31 is rotated counterclockwise in FIG. The second protrusion 31b passes through the escape window 33 of the lock rod 5 when the cam plate 31 is rotated in the clockwise direction in FIG. Thus, the reset operation rod 8 is engaged with the upper side of the engagement hole 34 to slide the reset operation rod 8 upward.
[0034]
The mounting plate 2 is provided with a plurality of set screw insertion holes 2b, and the locking device 1 is attached to the back surface of the free end of the front frame of the pachislot machine with the set screw.
[0035]
In FIG. 7, the locking device 1 having the above structure is fixed to the back surface of the free end of the front frame 37 of the pachislot machine with a screw (not shown) using the set screw insertion hole 2 b of the mounting plate 2, On the other hand, the brackets 14 and 14 are positioned at positions where they engage with the flange members 7 and 7 of the locking device 1 in the locked state, and screws (see FIG. (Not shown) shows a fixed state. In FIG. 7, the front frame 37 is shown in a released state with a hinge (not shown) as a fulcrum with respect to the main body frame 38.
In the locking device 1 in this state, due to the urging force of the tension spring 26, the locking rod 5 is in the upper position, the hook member 7 is in the locking position, and the reset operating rod 8 is in the lower position.
[0036]
The front frame 37 is in a state where the free end side is slightly lowered due to the weight of various devices attached thereto. When the front frame 37 is closed with respect to the main body frame 38 using a hinge (not shown) as a fulcrum, first, the abutting member 13 of the locking device 1 rides on the receiving member 16 and the free end side of the front frame 37 faces upward. The hook member 7 of the locking device 1 and the receiving metal fitting 14 are adjusted to a positional relationship suitable for locking. Next, when the outer edge 7d of the claw portion 7b comes into contact with the receiving metal member 14, the claw member 7 resists the urging force of the tension spring 26, and the shaft center O of the support shaft 6 is moved as shown in FIG. Rotate upward to the center. Then, when the lower end of the claw portion 7b of the collar member 7 gets over the catch metal 14, the collar member 7 is rotated downward by the restoring force of the tension spring 26 and returned to the locked position, whereby the catch metal 14 is attached to the catch metal 14. Is engaged, and the locking state shown in FIG.
[0037]
As is clear from the locked state of FIG. 8B, the notch 7a of the collar member 7 has a size (depth and width) for receiving the receiving bracket 14, and the notch side of the collar claw part 7b is the support shaft 6. This is an arcuate engagement edge 7c having a radius R centered on the shaft center O, and the radius r of the metal fitting 14 is smaller than the radius R of the engagement edge 7c. Thereby, even if a gap (backlash) does not occur between the engagement edge 7c of the collar member 7 and the receiving metal member 14 in the locked state, as described above, the collar member rotated upward at the time of locking. 7, the tip of the claw portion 7 b gets over the receiving bracket 14, and then when the flange member 7 tries to return to the locked position by the restoring force of the tension spring 26, the receiving bracket 14 and the engaging edge 7 c are in point contact. Therefore, the generated frictional force is very small and does not return to the locked position and is not caught on the way. Thus, it is possible to smoothly return to the locking position while sliding and to securely lock. Needless to say, unlocking can be performed smoothly as well.
[0038]
In the locked state, the shaft center O of the support shaft 6, the shaft center Q of the receiving bracket 14, and the contact P between the engagement edge 7 c of the collar member 7 and the tangent parallel to the sliding direction X of the locking collar 5. Is positioned on the straight line Y, and the receiving metal fitting 14 can be engaged at a deep engagement position of the notch 7a, and a reliable locking state can be secured. The contact P also serves as a contact point where the arcuate engagement edge 7 c of the flange member 7 circumscribes the receiving metal fitting 14.
[0039]
In this locked state, even if it is attempted to pry the front frame 37 horizontally by using the hinge as a fulcrum, the receiving bracket 14 is in contact with the arc-shaped engagement edge 7c of the flange member 7 at the contact point P, and the force is a straight line Y It only acts in the direction (horizontal direction), and there is no fear that the collar member 7 will rotate in the unlocking direction around the support shaft 6, and an unauthorized operation is performed between the front frame 37 and the main body frame 38. There is no gap or the like that can be performed.
The receiving bracket 14 corresponding to the locking device 1 is more robust than a conventional plate-shaped receiving bracket, and can withstand a large force to open the front frame 37, so that it is safe and reliable. Can be locked.
And there is a great advantage that there is no need to adjust the state of engagement with the heel member with pliers or the like unlike a conventional plate-shaped metal fitting.
[0040]
Even if a gap (backlash) is provided between the engagement edge 7c of the flange member 7 and the receiving metal fitting 14 in the locked state in consideration of an attachment error or the like, the gap (backlash) is as shown in FIG. Compared to a conventional locking device corresponding to a plate-shaped metal fitting, the amount of the locking device is small, so that there is no gap between the front frame 37 and the main body frame 38 to allow unauthorized operation.
[0041]
Further, as shown in FIG. 9, compared to the radius R from the axis O of the support shaft 6 to the arcuate engagement edge 7 c of the flange member 7, the axis of the support metal 14 from the axis O of the support shaft 6. If the sum (L + r) of the distance L to the center Q and the radius r of the metal fitting 14 is slightly larger, it will not be locked, so it is easy to find the locking device 1 or the metal fitting 14 being attached incorrectly Yes, there is no fear of overlooking the locking failure of the pachislot machine.
[0042]
Moreover, since this locking device 1 rotates the collar member 7 in conjunction with the sliding movement of the locking rod 5, the protrusion 11 formed on the locking rod 5 is inserted into the long hole 10 of the base portion 7 e of the collar member 7 during assembly. The protrusion 11 is engaged with the long hole 10, and the long holes 19 at the upper and lower ends of the locking bar 5 are aligned with the insertion holes (not shown) through which the support shaft 6 of the bar member 7 is inserted. The shaft 6 may be inserted into the long hole 19 of the locking rod and the insertion hole of the support shaft 6 of the rod member 7 and fixed to the support plate 3. This eliminates the need for a step of caulking the hook member and the lock hook with the connecting pin as in a conventional locking device, thereby reducing the manufacturing cost.
[0043]
Further, in the conventional locking device, if the axis of the support shaft that enables rotation of the eaves member and the axis of the connecting pin that connects the eaves member and the locking eaves are not parallel, the rotation of the eaves member , And / or an excessive force is required for the sliding of the locking rod or it is squeezed, so that the engagement between the flange member and the receiving metal fitting is not smoothly and reliably performed or the engagement state is insufficient. However, this locking device does not have such drawbacks, and the locking and unlocking is smooth and reliable, and can be easily performed. it can.
[0044]
Further, in the locked state where the front frame 37 is closed with respect to the main body frame 38, the receiving brackets 14, 14 are housed in the recesses 3 a, 3 a of the support plate 3. Even if the engagement between the seventh and seventh members and the metal fittings 14 and 14 is attempted to be disengaged, the lower edges of the recesses 3a and 3a cannot abut on the metal fittings 14 and 14 and lift.
[0045]
In the locked state, when a key (not shown) is inserted into the cylinder lock 17 and the cam plate 31 is rotated counterclockwise in FIG. 2 by the key operation, the first protrusion 31a of the cam plate 31 is locked. 5 is engaged with the lower side of the engagement hole 32, and the locking rod 5 slides downward against the urging force of the tension spring 26, so that the protrusion 11 inserted into the long hole 10 of the base portion 7e of the flange member 7 is provided. As a result, the flange member 7 rotates upward about the axis O of the support shaft 6, and the engagement between the flange members 7, 7 and the brackets 14, 14 is released and unlocked.
Therefore, when the front frame 37 is rotated in the opening direction with the hinge as a fulcrum, the contact member 13 can descend the receiving member 16 and open the front frame 37 with respect to the main body frame 38 with the hinge as a fulcrum.
When this key operation is finished, the locking rod 5 returns to the position shown in FIG. 1 by the urging force of the tension spring 26.
[0046]
When the key is inserted into the cylinder lock 17 and the cam plate 31 is rotated in the clockwise direction in FIG. 2 in the locked state, the second protrusion of the cam plate 31 is placed on the upper side of the engagement hole 34 of the reset operating rod 8. When the reset operation rod 8 is engaged and slides upward against the urging force of the tension spring 26, a reset switch (not shown) is operated by the reset operation piece 22 to output a reset signal. The pachislot machine is reset by the reset signal. When the reset operation by the key operation is released, the reset operating rod 8 returns to the initial position shown in FIG. 2 by the urging force of the tension spring 26.
Although the receiving metal fitting 14 is a cylindrical pin, it is not limited to this. For example, it may be a hexagonal column-shaped pin 39 as shown in FIG. 10, and an elliptical column-shaped pin 40 as shown in FIG. It is possible to use pins having various cross-sectional shapes.
[0047]

It can be rotated between a locked position and an unlocked position around the center. In this structure, the locking rod 45 can be unlocked by moving it upward, so that when the cam plate is rotated clockwise, the locking rod is engaged with the engagement hole of the locking rod from below. Appropriate changes may be made, such as sliding upward.
[0049]
