Description

【０００１】
【発明の属する技術分野】
本発明は、パチンコ機の前面枠を本体枠に対し施錠すると共に、前面枠内に開閉可能に取付けられたガラス枠を、前面枠に対し施錠するパチンコ機用施錠装置に関する。
【０００２】
【従来の技術】
パチンコ機の前面枠を本体枠に対し施錠する施錠装置として、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材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板が固定されてなる施錠装置が、一般に使用されている。
【０００３】
一方、パチンコ機の前面枠内には、ガラスを嵌め込んだガラス枠が開閉可能に取付けられているが、この種の施錠装置には、ガラス枠を施錠するガラス枠用施錠具は設けられてなく、単にガラス枠用施錠具を解錠するための作動片付き作動杆が、施錠装置の基枠内に設けられ、シリンダ錠によるカム板の回動によりその作動杆を摺動させる機構が設けられているのみである。
【０００４】
このため、ガラス枠用施錠具を別個に前面枠の内側に取付ける必要があり、その際の取付け作業に多くの工数がかかると共に、施錠装置側の作動片をガラス枠用施錠具側の受け具に合せるように、位置調整を行なう必要があり、取付け時の調整作業にも多くの作業工数がかかる問題があった。
【０００５】
そこで、本出願人は、特開平１１−２０６９９９号公報により、取付板と支持板からなる縦長の基枠の内側に、上部と下部に鉤部を一体的に設けた摺動杆が摺動可能に配設され、基枠の取付板にシリンダ錠がその錠軸を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板が固定され、基枠の取付板の上部と下部に挿入孔が形成され、挿入孔に対応した位置に係止孔を設けたガラス枠施錠杆が、基枠内の取付板に沿って摺動可能に配設され、ガラス枠施錠杆の一部に前記カム板が係合可能な係合部が設けられ、パチンコ機のガラス枠の内側に設けたガラス枠鉤部が、ガラス枠の閉鎖時に、挿入孔からガラス枠施錠杆の係止孔に進入して係止・施錠され、シリンダ錠を前面枠の解錠時と反対方向に回してカム板を同方向に回動させることにより、ガラス枠施錠杆を摺動させてガラス枠鉤部と係止孔の係合を解きガラス枠を解錠する構造のパチンコ機用施錠装置を提案した。
【０００６】
【発明が解決しようとする課題】
ところで、近年、パチンコホールでは、営業中にパチンコ機の前面枠やガラス枠を不正に解錠し、本体枠内の遊技プログラムを格納したＲＯＭなどを不正なものと取り替えてしまい、多くの入賞球を不正に払い出すようにする不正行為が行われる事件が発生している。このような不正解錠は、通常、本体枠と前面枠の隙間から針金や線材などを差込み、針金の先端で施錠装置の摺動杆やガラス枠施錠杆を引っ掛けて、解錠方向にそれを動かすことにより行われている。このために、針金などを用いて行われる不正解錠を未然に防止することができるパチンコ機用施錠装置が要望されていた。
【０００７】
本発明は、上記の課題を解決するためになされたもので、針金などを用いて行われる不正解錠を未然に防止することができるパチンコ機用施錠装置を提供することを目的とする。
【０００８】
【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、本発明のパチンコ機用施錠装置は、パチンコ機の前面枠を本体枠に対し施錠し、且つガラス枠を前面枠に対し施錠するパチンコ機用施錠装置において、縦長の基枠が取付板と支持板を断面略Ｌ形に曲折して形成され、基枠の支持板の内側に１本の摺動杆が摺動可能に配設され、基枠内の上部と下部に鉤部材が独立して摺動可能で且つ摺動杆に対し解錠方向にのみ連動可能に連結されて配設され、鉤部材は本体枠側の受け金具に係止可能とされ、基枠の取付板にシリンダ錠がその錠軸を基枠の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可能なカム板が固定され、基枠の取付板の上部と下部に挿入孔が形成され、上部と下部の挿入孔に対応した位置に各々係止孔を有するガラス枠施錠部材が、基枠内の取付板に沿って独立して摺動可能で且つ摺動杆に対し解錠方向にのみ連動可能に連結されて配設され、ガラス枠の閉鎖時、ガラス枠側のガラス枠鉤部がガラス枠施錠部材の係止孔に係止され、カム板によらず摺動杆を鉤部材の解錠方向に摺動させたとき、摺動杆の移動を阻止するストッパが、摺動杆におけるカム板との係合部の下側であってカム板側に設けられたことを特徴とする。
【００１０】
【作用】
このような構成のパチンコ機用施錠装置では、パチンコ機の前面枠を本体枠に対し閉じると、施錠装置の上下の鉤部材が本体枠側の受け金具に当って摺動しながら係止され、施錠状態となる。
【００１１】
それを解錠する場合は、キーによってシリンダ錠を回し、カム板を回転させると、カム板が摺動杆と係合してこれを摺動させ、上下の鉤部材が連動して解錠方向に移動することによって、本体枠の受け金具との係合が外れ、前面枠は開放可能な状態となる。
【００１２】
一方、前面枠内のガラス枠を前面枠に対し閉じると、ガラス枠内のガラス枠鉤部が前面枠側に取り付けた本施錠装置の取付板の挿入孔からガラス枠施錠部材の係止孔に進入し、これを摺動させながら、ガラス枠が閉じられたとき、ガラス枠鉤部が係止孔の縁部に係止され、ガラス枠は施錠状態となる。
【００１３】
ガラス枠を解錠する場合は、シリンダ錠のキーを逆方向に回して、カム板を同方向に回動させる。このとき、カム板の係合凸部が摺動杆と係合して摺動杆を上記とは逆方向に摺動させる。この摺動杆の上記とは逆方向の摺動に連動して、ガラス枠施錠部材が摺動し、ガラス枠施錠部材の係止孔とガラス枠鉤部との係合が外れ、ガラス枠は解錠される。
【００１４】
一方、施錠された状態で、パチンコ機の隙間から針金などが差し込まれ、上部または下部の鉤部材に引っ掛けて、上部または下部の一方を鉤部材を上方（解錠側）に引いた場合、鉤部材の一方は上方に移動するが、上部と下部の鉤部材は一体ではなく独立して形成され、解錠側には独立して移動可能であるから、針金が掛けられた一方の鉤部材が解錠方向に移動した場合でも、他方の鉤部材は移動しない。したがって、針金などにより一方の鉤部材が解錠方向に移動したとしても、他方の鉤部材は施錠状態を保持するから、前面枠の不正解除は防止される。
【００１５】
また、同様に、上部と下部のガラス枠施錠部材も解錠側には独立して移動するように、摺動杆に対して連動可能に連結されているから、一方のガラス枠施錠部材に針金などを引っ掛けて行う不正解錠を防止することができる。
【００１６】
【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は施錠装置の正面図を、図２はその背面図を示し、図３はその右側面図を、図４はその左側面図を各々示している。１は取付板２と支持板３を断面略Ｌ形に曲折して一体成形してなる縦長の基枠で、取付板２には複数の取付孔が穿設され、さらにその上部と下部に、後述のガラス枠鉤部２６，２７が進入する挿入孔１４，１５が矩形孔として形成される。また、その挿入孔１４，１５の下側の取付板２上には、ガイドピン２ａ、２ｂが後述のガラス枠施錠部材１０，１１の摺動をガイドするために、取り付けられている。
【００１７】
上部と下部に鉤部材４，５を上方移動時のみ連動して摺動させる摺動杆６が支持板３の内側に、上下に摺動可能に配設される。摺動杆６は、図６に示すように、金属板により帯状に形成され、上部と下部にガイド孔６ｅ、６ｆを設け、中間部に手動操作用の操作部６ｇを突設し、下部のガイド孔６ｆの少し上には、後述のカム板８が係合可能な２個の係合部６ｃ、６ｄが矩形孔として形成されて構成される。係合部６ｄは前面枠を解錠する際にシリンダ錠７を右に回したとき、カム板８の第一係合凸部８ａが係合し、係合部６ｃはガラス枠を解錠する際にシリンダ錠７を左に回したとき、カム板８の第二係合凸部８ｂが係合する。
【００１８】
上部と下部の鉤部材４，５は三角形頭部を有しその中間部に係合凹部を下側に向けて形成されている。また、上下の鉤部材４，５には、その裏側から各々ガイドピン４ａ，５ａが、支持板３の上部と下部に設けた小判形のガイド孔３ａ、３ｂに通して、鉤部材４，５に固定され、さらに、鉤部材４，５は、図５に示すように、支持板３の上部と下部に設けたガイド部３ｃ、３ｄにガイドされ保持される。このガイドピン４ａ，５ａとガイド部３ｃ、３ｄによって鉤部材４，５は、所定の範囲で上下に摺動可能に保持される。
【００１９】
さらに、上記ガイドピン４ａ，５ａが上記摺動杆６のガイド孔６ｅ，６ｆに挿通されており、且つ鉤部材４，５と取付板２の間にコイルばね９ｂ、９ｄが掛けられ、鉤部材４，５は下方に付勢される。また、ガイドピン４ａ，５ａが摺動杆６のガイド孔６ｅ，６ｆと支持板３のガイド孔３ａ、３ｂの下側縁部に当接しているから、摺動杆６が上方に摺動するとき、鉤部材４，５は連動して移動する。したがって、各々の鉤部材４，５は、独立して上方に移動可能であり、針金などで上下の鉤部材４，５を上方に移動させる場合は、両方の鉤部材４，５に引っ掛けて上に引かなければならず、針金などで一方のみの鉤部材４または５を引っ掛けて上に引いただけでは、不正解錠をすることができない。
【００２０】
一方、ガラス枠施錠装置を構成するガラス枠施錠部材１０，１１は、図５、図６に示すように、金属板を断面コ字状に折り曲げて形成され、取付板２側に係止孔１２，１３が矩形孔として形成され、この係止孔１２，１３は取付板２側の挿入孔１４，１５に対向して配置される。また、このガラス枠施錠部材１０、１１には、各々ガイド孔１０ａ，１０ｂ、１１ａ，１１ｂが設けられ、ガイド孔１０ａ、１１ａには、摺動杆６の上部と下部に固定されたガイドピン６ａ，６ｂが係合している。
【００２１】
また、ガイド孔１０ｂ、１１ｂには、取付板２の上部と下部に固定されたガイドピン２ａ，２ｂが係合し、ガラス枠施錠部材１０，１１と取付板２の間にコイルばね９ａ、９ｃが掛けられ、ガラス枠施錠部材１０，１１は上方に付勢され、ガイドピン２ａ，２ｂがガラス枠施錠部材１０，１１のガイド孔１０ｂ，１１ｂの下側縁部に当接し、ガイドピン６ａ、６ｂがガラス枠施錠部材１０，１１のガイド孔１０ａ，１１ａの下側縁部に当接した状態で停止する。このようなガラス枠施錠部材１０，１１の停止位置において、その係止孔１２，１３は、取付板２側の挿入孔１４，１５の上側に対向して位置する。
【００２２】
したがって、ガラス枠施錠部材１０，１１は、後述のガラス枠鉤部２６，２７がその係止孔１２，１３に進入したとき、その鉤部に押されコイルばねの付勢力に抗して下方に摺動し、その後、コイルばねの付勢力で元の位置に戻り、ガラス枠鉤部２６，２７を係止する。また、ガラス枠施錠部材１０，１１は、解錠時には、摺動杆６の下方への摺動に伴いそれに連結されて下方に摺動し、ガラス枠鉤部２６，２７と係止孔１２，１３の係合が解除される。
【００２３】
さらに、取付板２の下部の拡幅部分に、シリンダ錠７を取り付けるための異形孔が形成されると共に、取付ブラケット部１８が形成される。取付ブラケット部１８は、取付板２の一部を切り開き、それを内側に曲げて凹状に形成され、シリンダ錠７の元部を基枠１の内側に入れ、その元部（フランジ）をそこに固定する。シリンダ錠７は、その元部にフランジ７ａを有し、錠軸を基枠１の内側に挿入するようにして、フランジ７ａを取付ブラケット部１８にねじ止めして固定される。
【００２４】
このように、基枠１の内側に凹状に形成された取付ブラケット部１８にシリンダ錠７を固定することにより、シリンダ錠の７の前面への突き出し長を短くし、規格化されたシリンダ錠を厚さの薄い前面枠にも良好に使用することができる。シリンダ錠７の錠軸には第一係合凸部８ａと第二係合凸部８ｂを持つカム板８が固定される。
【００２５】
シリンダ錠７を操作してカム板８を図２反時計方向に回動させた場合、カム板の第一係合凸部８ａが摺動杆６の係合部６ｄに係合し、摺動杆６を上方に摺動させ、鉤部材４，５を上方に摺動させる。このとき、鉤部材４，５と本体枠側の受け金具２４，２５との係合が解除され、前面枠が解錠される。したがって、この鉤部材４，５、摺動杆６、カム板８、シリンダ錠７によって、前面枠の施錠・解錠機構が形成されることになる。
【００２６】
一方、シリンダ錠７を操作してカム板８を図２時計方向に回動させた場合、カム板の第二係合凸部８ｂが摺動杆６の係合部６ｃに係合し、摺動杆６を下方に摺動させ、ガラス枠施錠部材１０，１１を下方に摺動させる。このとき、ガラス枠施錠部材１０，１１とガラス枠側のガラス枠鉤部２６，２７の係合が解除され、ガラス枠が解錠される。
【００２７】
したがって、ガラス枠施錠部材１０，１１、摺動杆６、カム板８、シリンダ錠７によって、ガラス枠の施錠・解錠機構が形成されることになる。従来のこの種の施錠装置では、上下のガラス枠施錠部材が一体に形成され、大型となっていたが、本施錠装置では、ガラス枠施錠部材１０，１１が別個に小形化されて形成され、前面枠用解錠機構の摺動杆６に連係して解錠動作を行うようにしている。このため、施錠装置の軽量化が図れ、構造も簡単となる。
【００２８】
一方、摺動杆６における係合部６ｄの下側のカム板側には、ストッパ１６が内側に突出して設けられる。このストッパ１６は、摺動杆６の不正な上方摺動を防止するもので、施錠状態において、摺動杆６が上方に針金などで不正に移動したとき、図２，３の通常位置にあるカム板８の第一係合凸部８ａにストッパ１６が当接し、摺動杆６と鉤部材４，５がその解錠位置まで移動することを阻止するように作用する。
【００２９】
このように構成された施錠装置は、図８に示すように、パチンコ機における例えば合成樹脂製の前面枠２１の内側に、シリンダ錠７の先端を前面に露出させ、鉤部材４，５をパチンコ機の本体枠２０側に突出した状態で、取付板２を用いて縦に取付けられる。
【００３０】
一方、本体枠２０の内側の鉤部材４，５に対応した上下位置には、受け金具２４、２５が固定される。さらに、パチンコ機の前面にはガラス枠２２が前面枠２１の開口部にヒンジを介して開閉可能に取付けられ、そのガラス枠２２の自由端部に、且つガラス枠施錠部材１０，１１の係止孔１２、１３に進入可能な位置に、ガラス枠鉤部２６、２７が内側に突出して固定される。
【００３１】
このようなパチンコ機用施錠装置は、パチンコ機における前面枠２１を本体枠２０に対し閉じると、図８に示すように、施錠装置の上下の鉤部材４，５が、各々独立して、コイルばね９ｂ、９ｄの付勢力に抗して、本体枠２０側の受け金具２４、２５に当りながら上方に移動し、その後、コイルばね９ｂ、９ｄの付勢力により戻って受け金具に係止され、施錠状態となる。
【００３２】
それを解錠する場合は、キーによってシリンダ錠７の錠軸を回し、カム板８を図２反時計方向に回転させると、カム板８の第一係合凸部８ａが摺動杆６の係合部６ｄと係合してこれを上方へ摺動させ、摺動杆６の上昇時のみ連動する上下の鉤部材４，５を上に移動させる。この鉤部材４，５の上移動によって、本体枠の受け金具２４、２５との係合が外れ、前面枠２１は開放可能な状態となる。
【００３３】
一方、前面枠２１内のガラス枠２２を前面枠２１に対し閉じると、図７に示すように、ガラス枠２２の内側に突出したガラス枠鉤部２６、２７が、挿入孔１４，１５から基枠１内に進入し、ガラス枠施錠部材１０，１１の係止孔１２、１３に入る。そして、ガラス枠施錠部材１０，１１をコイルばね９ａ，９ｃの付勢力に抗して下方に摺動させた後、コイルばね９ａ，９ｃの付勢力によりガラス枠施錠部材１０，１１が上方に戻り、これにより、ガラス枠鉤部２６、２７が係止孔１２、１３の縁部に係止され、ガラス枠２２は施錠状態となる。
【００３４】
ガラス枠２２を解錠する場合は、シリンダ錠７のキーを逆方向に回して、カム板８を図２時計方向へ回動させると、図７に示すように、カム板８の第二係合凸部８ｂが摺動杆６の係合部６ｃと係合し、これをコイルばね９ａ，９ｃの付勢力に抗して下方へ摺動させ、摺動杆６の下方への摺動時にのみ連動する上下のガラス枠施錠部材１０，１１を下方に摺動させる。このガラス枠施錠部材１０，１１の係止孔１２、１３の下方への移動動作によって、ガラス枠２２のガラス枠鉤部２６、２７と係止孔１２、１３の縁部の係合が外れ、ガラス枠２２は開放される。
【００３５】
一方、施錠された状態で、図１０に示すように、パチンコ機の隙間から針金ｗなどが差し込まれ、鉤部材４又は５に引っ掛けて、鉤部材４または５を上方に引いた場合、鉤部材４または５は上方に移動するが、鉤部材４，５は一体ではなく独立して形成され、上方には独立して移動可能であるから、針金ｗが掛けられた一方の鉤部材４または５のみが解錠方向に移動し、他方の鉤部材４または５は移動しない。したがって、針金などにより一方の鉤部材が解錠方向に移動したとしても、他方の鉤部材は施錠状態を保持するから、前面枠の不正解除は防止される。
【００３６】
また、針金などを摺動杆６に引っ掛けてそれを上方に摺動させて解錠しようとした場合には、図１１のように、摺動杆６のカム板側に設けたストッパ１６がカム板８の第一係合凸部８ａに当たり、摺動杆６の解錠側への移動を阻止するから、矢張り前面枠の不正解錠は防止される。
【００３７】
一方、ガラス枠施錠部材１０，１１も、摺動杆６に対しては独立して下方に移動可能に形成されているから、パチンコ機の隙間から差し込まれた針金などをガラス枠施錠部材１０または１１に引っ掛けて不正に解除方向の下方に摺動させたとしても、一方のみのガラス枠施錠部材１０または１１の移動では、ガラス枠は解錠状態とならず、不正解錠を防止することができる。
【００３８】
【発明の効果】
以上説明したように、上部と下部の鉤部材が一体ではなく独立して摺動可能に形成され、解錠方向には独立して移動可能であるから、パチンコ機の隙間から針金などが差し込まれ、一方の鉤部材に引っ掛けて、それを上方に引いたとしても、一方の鉤部材は移動するが、他方の鉤部材は施錠状態を保持して、前面枠の不正解除を防止することができる。また、上部と下部のガラス枠施錠部材も、一体ではなく、別体で独立して摺動可能に形成され、解錠側には独立して移動可能であるから、一方のガラス枠施錠部材に針金などを引っ掛けて行うガラス枠の不正解錠を防止することができる。また、上下の鉤部材と上下のガラス枠施錠部材は１本の摺動杆により解錠方向に動かす構造であるから、従来に比べ、ガラス枠施錠部材は小形化され、構造が簡単で、軽量化を図ることができる。さらに、カム板によらずに摺動杆の解錠方向への移動を阻止するストッパを設けることにより、隙間から差し込まれた針金などを摺動杆に引っ掛けて、摺動杆を解錠側に動かそうとした場合、摺動杆は解錠側に動かず、不正解錠を防止することができる。

[0006]
[Problems to be solved by the invention]
By the way, in recent years, pachinko halls illegally unlocked the front frame and glass frame of pachinko machines during operation, and replaced ROMs that stored game programs in the main frame with illegal ones, and many winning balls Incidents have been made in which fraudulent acts to illegally pay out Such unauthorized unlocking usually involves inserting a wire or wire from the gap between the main body frame and the front frame, hooking the sliding rod of the locking device or the glass frame locking rod with the tip of the wire, and releasing it in the unlocking direction. It is done by moving. For this reason, there has been a demand for a locking device for a pachinko machine that can prevent unauthorized unlocking using a wire or the like.
[0007]
The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a locking device for a pachinko machine that can prevent unauthorized unlocking using a wire or the like.
[0008]
[Means for Solving the Problems]
In order to achieve the above object, a locking device for a pachinko machine according to the present invention is a vertically long locking device for a pachinko machine that locks the front frame of the pachinko machine to the main body frame and locks the glass frame to the front frame. The base frame is formed by bending the mounting plate and the support plate into a substantially L-shaped cross section, and one sliding rod is slidably disposed inside the support plate of the base frame. The hook member can be slid independently at the lower part and is connected to the sliding hook so as to be interlocked only in the unlocking direction, and the hook member can be locked to the receiving bracket on the main body frame side. A cylinder lock is fixed to the frame mounting plate so that the lock shaft is inserted into the inside of the base frame, and a cam plate that can be engaged with a sliding rod is fixed to the tip of the lock shaft. And a glass frame locking member having locking holes at positions corresponding to the upper and lower insertion holes, respectively. It can be slid independently along the mounting plate and is connected to the sliding rod so that it can be interlocked only in the unlocking direction. When the glass frame is closed, the glass frame flange on the glass frame side is the glass frame. A stopper that prevents the movement of the sliding rod when the sliding rod is slid in the unlocking direction of the flange member regardless of the cam plate is locked in the locking hole of the locking member. It is provided below the engaging portion with the cam plate side .
[0010]
[Action]
In the locking device for a pachinko machine having such a configuration, when the front frame of the pachinko machine is closed with respect to the main body frame, the upper and lower hook members of the locking device are locked while sliding against the receiving metal fitting on the main body frame side, It becomes locked.
[0011]
When unlocking it, turn the cylinder lock with the key and rotate the cam plate. The cam plate engages the sliding rod and slides it, and the upper and lower rod members are interlocked to unlock the direction. By moving to, the engagement of the main body frame with the metal fitting is released, and the front frame becomes openable.
[0012]
On the other hand, when the glass frame in the front frame is closed with respect to the front frame, the glass frame collar portion in the glass frame changes from the insertion hole of the mounting plate of the locking device attached to the front frame side to the locking hole of the glass frame locking member. When the glass frame is closed while entering and sliding, the glass frame collar is locked to the edge of the locking hole, and the glass frame is locked.
[0013]
When unlocking the glass frame, the key of the cylinder lock is turned in the reverse direction to rotate the cam plate in the same direction. At this time, the engaging convex portion of the cam plate engages with the sliding rod to slide the sliding rod in the opposite direction. The glass frame locking member slides in conjunction with the sliding of the sliding rod in the opposite direction to the above, and the engagement between the locking hole of the glass frame locking member and the glass frame collar portion is released. Unlocked.
[0014]
On the other hand, when a wire is inserted from the gap of the pachinko machine in the locked state, hooked on the upper or lower hook member, and the upper or lower hook member is pulled upward (unlocked), One of the members moves upward, but the upper and lower hook members are not integrated but formed independently, and can be moved independently on the unlocking side. Even when moved in the unlocking direction, the other flange member does not move. Therefore, even if one hook member moves in the unlocking direction due to a wire or the like, the other hook member maintains the locked state, so that the unauthorized release of the front frame is prevented.
[0015]
Similarly, the upper and lower glass frame locking members are connected to the sliding rod so as to move independently to the unlocking side, so that one of the glass frame locking members has a wire. It is possible to prevent unauthorized unlocking by hooking.

DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings. 1 is a front view of the locking device, FIG. 2 is a rear view thereof, FIG. 3 is a right side view thereof, and FIG. 4 is a left side view thereof. Reference numeral 1 denotes a vertically long base frame formed by bending a mounting plate 2 and a support plate 3 into a substantially L-shaped cross section, and a plurality of mounting holes are formed in the mounting plate 2, and at the upper and lower portions thereof, Insertion holes 14 and 15 into which glass frame flanges 26 and 27 described later enter are formed as rectangular holes. Further, guide pins 2a and 2b are mounted on the lower mounting plate 2 of the insertion holes 14 and 15 in order to guide sliding of glass frame locking members 10 and 11, which will be described later.
[0017]
A sliding rod 6 for sliding the collar members 4 and 5 in conjunction with the upper and lower portions only when moving upward is disposed inside the support plate 3 so as to be slidable up and down. As shown in FIG. 6, the sliding rod 6 is formed in a strip shape by a metal plate, provided with guide holes 6e and 6f in the upper and lower portions, and provided with an operation portion 6g for manual operation in the middle portion, Slightly above the guide hole 6f, two engaging portions 6c and 6d with which a cam plate 8 described later can be engaged are formed as rectangular holes. When the cylinder lock 7 is turned to the right when the engaging portion 6d unlocks the front frame, the first engaging convex portion 8a of the cam plate 8 is engaged, and the engaging portion 6c unlocks the glass frame. When the cylinder lock 7 is turned counterclockwise, the second engaging projection 8b of the cam plate 8 is engaged.
[0018]
The upper and lower flange members 4 and 5 have triangular heads and are formed in the middle with the engaging recesses facing downward. In addition, the upper and lower flange members 4 and 5 have guide pins 4a and 5a from the back side thereof through oval guide holes 3a and 3b provided in the upper and lower portions of the support plate 3, respectively. Further, as shown in FIG. 5, the flange members 4 and 5 are guided and held by guide portions 3 c and 3 d provided on the upper and lower portions of the support plate 3. The flange members 4 and 5 are held by the guide pins 4a and 5a and the guide portions 3c and 3d so as to be slidable up and down within a predetermined range.
[0019]
Further, the guide pins 4a and 5a are inserted into the guide holes 6e and 6f of the sliding rod 6, and coil springs 9b and 9d are hung between the flange members 4 and 5 and the mounting plate 2, respectively. 4 and 5 are biased downward. Further, since the guide pins 4a and 5a are in contact with the guide holes 6e and 6f of the sliding rod 6 and the lower edges of the guide holes 3a and 3b of the support plate 3, the sliding rod 6 slides upward. At this time, the eaves members 4 and 5 move in conjunction with each other. Accordingly, each of the hook members 4 and 5 can be independently moved upward. When the upper and lower hook members 4 and 5 are moved upward by a wire or the like, the hook members 4 and 5 are hooked on both the upper and lower hook members 4 and 5. If the hook member 4 or 5 is only hooked with a wire or the like and pulled upward, unauthorized unlocking cannot be performed.
[0020]
On the other hand, the glass frame locking members 10 and 11 constituting the glass frame locking device are formed by bending a metal plate into a U-shaped cross section as shown in FIGS. , 13 are formed as rectangular holes, and the locking holes 12, 13 are arranged to face the insertion holes 14, 15 on the mounting plate 2 side. The glass frame locking members 10 and 11 are provided with guide holes 10a, 10b, 11a and 11b, respectively, and the guide holes 6a and 11a have guide pins 6a fixed to the upper and lower parts of the sliding rod 6, respectively. , 6b are engaged.
[0021]
Further, guide pins 2a and 2b fixed to the upper and lower portions of the mounting plate 2 are engaged with the guide holes 10b and 11b, and coil springs 9a and 9c are interposed between the glass frame locking members 10 and 11 and the mounting plate 2, respectively. The glass frame locking members 10 and 11 are biased upward, and the guide pins 2a and 2b abut against the lower edges of the guide holes 10b and 11b of the glass frame locking members 10 and 11, and the guide pins 6a and 6b stops in the state which contact | abutted to the lower edge part of the guide holes 10a and 11a of the glass frame locking members 10 and 11. FIG. In such a stop position of the glass frame locking members 10, 11, the locking holes 12, 13 are positioned facing the upper side of the insertion holes 14, 15 on the mounting plate 2 side.
[0022]
Accordingly, the glass frame locking members 10 and 11 are pushed downward by a glass spring against the urging force of the coil spring when the glass frame flanges 26 and 27 (described later) enter the locking holes 12 and 13 when the glass frame locking members 10 and 11 enter the locking holes 12 and 13. After that, the glass frame collar portions 26 and 27 are locked by returning to the original position by the biasing force of the coil spring. Further, when unlocking, the glass frame locking members 10, 11 are connected to and slide downward as the sliding rod 6 slides downward, and the glass frame locking portions 26, 27 and the locking holes 12, 13 is disengaged.
[0023]
Furthermore, a deformed hole for attaching the cylinder lock 7 is formed in the widened portion at the lower part of the mounting plate 2, and a mounting bracket portion 18 is formed. The mounting bracket portion 18 is formed by opening a part of the mounting plate 2 and bending it inward to form a concave shape. The base portion of the cylinder lock 7 is placed inside the base frame 1 and its base portion (flange) is placed there. Fix it. The cylinder lock 7 has a flange 7 a at its base portion, and is fixed by screwing the flange 7 a to the mounting bracket portion 18 so that the lock shaft is inserted inside the base frame 1.
[0024]
Thus, by fixing the cylinder lock 7 to the mounting bracket portion 18 formed in a concave shape inside the base frame 1, the protruding length of the cylinder lock 7 to the front surface is shortened, and a standardized cylinder lock is attached. It can also be used well for a thin front frame. A cam plate 8 having a first engaging convex portion 8a and a second engaging convex portion 8b is fixed to the lock shaft of the cylinder lock 7.
[0025]
When the cylinder lock 7 is operated and the cam plate 8 is rotated counterclockwise in FIG. 2, the first engagement convex portion 8a of the cam plate engages with the engagement portion 6d of the sliding rod 6 and slides. The scissors 6 are slid upward, and the scissors members 4 and 5 are slid upward. At this time, the engagement between the flange members 4 and 5 and the receiving brackets 24 and 25 on the main body frame side is released, and the front frame is unlocked. Therefore, the locking / unlocking mechanism of the front frame is formed by the flange members 4 and 5, the sliding rod 6, the cam plate 8, and the cylinder lock 7.
[0026]
On the other hand, when the cam plate 8 is rotated clockwise in FIG. 2 by operating the cylinder lock 7, the second engagement convex portion 8 b of the cam plate is engaged with the engagement portion 6 c of the sliding rod 6, and the sliding is performed. The sliding rod 6 is slid downward, and the glass frame locking members 10 and 11 are slid downward. At this time, the engagement between the glass frame locking members 10 and 11 and the glass frame flange portions 26 and 27 on the glass frame side is released, and the glass frame is unlocked.
[0027]
Therefore, the glass frame locking members 10 and 11, the sliding rod 6, the cam plate 8, and the cylinder lock 7 form a glass frame locking / unlocking mechanism. In this type of conventional locking device, the upper and lower glass frame locking members are integrally formed and are large, but in this locking device, the glass frame locking members 10 and 11 are separately reduced in size, The unlocking operation is performed in conjunction with the sliding rod 6 of the unlocking mechanism for the front frame. For this reason, the locking device can be reduced in weight and the structure can be simplified.
[0028]
On the other hand, a stopper 16 protrudes inwardly on the cam plate side below the engaging portion 6d of the sliding rod 6. The stopper 16 prevents the sliding rod 6 from being illegally slid upward. When the sliding rod 6 is illegally moved upward with a wire or the like in the locked state, the stopper 16 is in the normal position shown in FIGS. The stopper 16 comes into contact with the first engaging convex portion 8a of the cam plate 8 and acts to prevent the sliding rod 6 and the flange members 4 and 5 from moving to the unlocked position.
[0029]
As shown in FIG. 8, the locking device configured in this way has the front end of the cylinder lock 7 exposed on the front surface inside the front frame 21 made of, for example, a synthetic resin in the pachinko machine, and the hook members 4 and 5 are attached to the pachinko machine. In a state of protruding to the main body frame 20 side of the machine, it is mounted vertically using the mounting plate 2.
[0030]
On the other hand, receiving brackets 24 and 25 are fixed at the upper and lower positions corresponding to the flange members 4 and 5 inside the main body frame 20. Further, a glass frame 22 is attached to the front surface of the pachinko machine so as to be openable and closable through an opening of the front frame 21 via a hinge, and the glass frame locking members 10 and 11 are engaged with the free end of the glass frame 22. The glass frame collars 26 and 27 are fixed to protrude into the inside at positions where they can enter the holes 12 and 13.
[0031]
In such a locking device for a pachinko machine, when the front frame 21 of the pachinko machine is closed with respect to the main body frame 20, as shown in FIG. Against the biasing force of the springs 9b, 9d, it moves upward while hitting the receiving brackets 24, 25 on the side of the main body frame 20, and then returned by the biasing force of the coil springs 9b, 9d and locked to the receiving bracket, It becomes locked.
[0032]
When unlocking it, the lock shaft of the cylinder lock 7 is rotated by the key and the cam plate 8 is rotated counterclockwise in FIG. The engaging part 6d is engaged and slid upward, and the upper and lower hook members 4 and 5 interlocked only when the sliding hook 6 is raised are moved upward. By the upward movement of the flange members 4 and 5, the engagement of the main body frame with the receiving brackets 24 and 25 is released, and the front frame 21 becomes openable.
[0033]
On the other hand, when the glass frame 22 in the front frame 21 is closed with respect to the front frame 21, the glass frame flange portions 26 and 27 protruding inside the glass frame 22 are formed from the insertion holes 14 and 15 as shown in FIG. It enters the frame 1 and enters the locking holes 12 and 13 of the glass frame locking members 10 and 11. Then, after the glass frame locking members 10 and 11 are slid downward against the urging force of the coil springs 9a and 9c, the glass frame locking members 10 and 11 are returned upward by the urging force of the coil springs 9a and 9c. Thereby, the glass frame collar portions 26 and 27 are locked to the edge portions of the locking holes 12 and 13, and the glass frame 22 is locked.
[0034]
When unlocking the glass frame 22, when the key of the cylinder lock 7 is turned in the reverse direction and the cam plate 8 is rotated clockwise in FIG. 2, the second engagement of the cam plate 8 as shown in FIG. The mating projection 8b engages with the engaging portion 6c of the sliding rod 6 and slides it downward against the urging force of the coil springs 9a, 9c. Only the upper and lower glass frame locking members 10 and 11 that are interlocked with each other are slid downward. By the downward movement of the locking holes 12 and 13 of the glass frame locking members 10 and 11, the glass frame collar portions 26 and 27 of the glass frame 22 and the edges of the locking holes 12 and 13 are disengaged, The glass frame 22 is opened.
[0035]
On the other hand, in the locked state, as shown in FIG. 10, when a wire w or the like is inserted from the gap of the pachinko machine and hooked on the hook member 4 or 5, the hook member 4 or 5 is pulled upward. 4 or 5 moves upward, but the hook members 4 and 5 are not integrated but formed independently, and can move independently upward, so that one hook member 4 or 5 on which the wire w is hung is provided. Only moves in the unlocking direction, and the other flange member 4 or 5 does not move. Therefore, even if one hook member moves in the unlocking direction due to a wire or the like, the other hook member maintains the locked state, so that the unauthorized release of the front frame is prevented.
[0036]
In addition, when an attempt is made to unlock the wire by hooking the wire or the like on the sliding rod 6 and sliding it upward, the stopper 16 provided on the cam plate side of the sliding rod 6 is a cam as shown in FIG. Since it hits the first engaging convex portion 8a of the plate 8 and prevents the sliding rod 6 from moving to the unlocking side, unauthorized unlocking of the arrow-clad front frame is prevented.
[0037]
On the other hand, since the glass frame locking members 10 and 11 are also formed so as to be movable downward with respect to the sliding rod 6, the wire inserted through the gap of the pachinko machine is attached to the glass frame locking member 10 or Even if the glass frame locking member 10 or 11 moves only one side even if it is hooked on 11 and illegally slid downward, the glass frame is not unlocked, and unauthorized unlocking can be prevented. it can.
[0038]
【The invention's effect】
As described above, the upper and lower flange members are formed so as to be slid independently rather than integrally, and can be moved independently in the unlocking direction, so that a wire or the like is inserted from the gap of the pachinko machine. Even if one hook member is hooked and pulled upward, one hook member moves, but the other hook member holds the locked state and can prevent unauthorized release of the front frame. . In addition, the upper and lower glass frame locking members are not integrated, but are formed separately and slidable independently, and can be moved independently on the unlocking side. Unauthorized unlocking of the glass frame by hooking a wire or the like can be prevented. In addition, since the upper and lower hook members and the upper and lower glass frame locking members are moved in the unlocking direction by a single sliding hook, the glass frame locking members are smaller in size and simpler and lighter than conventional ones. Can be achieved. Furthermore, by providing a stopper that prevents the sliding rod from moving in the unlocking direction regardless of the cam plate, the wire inserted from the gap is hooked on the sliding rod and the sliding rod is moved to the unlocking side. When trying to move, the sliding rod does not move to the unlocking side, and unauthorized unlocking can be prevented.
