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、前面枠に対しガラス枠を施錠し、且つ前面枠内に開閉可能に取付けられた前パネルを施錠するパチンコ機の施錠装置に関する。
【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体の内側に、連結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連結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、錠軸の先端に連結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（例えば、実公昭５７−８８６７号公報等参照）。
【０００３】
【発明が解決しようとする課題】
一方、パチンコ機の前面枠内には、金枠が取付けられ、その金枠の上部に盤面を覆うガラス枠が開閉可能に取付けられ、金枠の下部には上皿等を取付けるための前パネルが開閉可能に取付けられている。通常、この前パネルの自由端側の縁部に、鉤部を有する施錠部材が上下摺動可能に取付けられ、前パネルを閉じた際に、施錠部材の鉤部が金枠側に設けた係止片に係止されて前パネルを施錠する構造となっている。
【０００４】
そして、前パネルを開く際には、先ず、ガラス枠を開いた状態で、正面側からその開口部に手を挿入し、前パネルに設けられた施錠部材を手で動かすことにより、係止片との係合を解いて前パネルを解錠するようにしている。
【０００５】
しかし、前パネルは、通常、比較的薄い金属板で形成され、同様の金属板でその施錠部材も形成されているため、解錠時に施錠部材を押し下げ操作する際に、前パネル自体を変形させる場合があり、その変形により施錠部材の鉤部と係止片の位置関係が悪化し、前パネルの施錠と解錠が円滑に行われなくなる問題があった。
【０００６】
そこで、本発明者らは、従来、特開平１０−６６７７５号公報において、前パネル施錠機構を設けた施錠装置を提案した。この施錠装置は、前パネル用作動杆が支持板に沿って鉤部を取付板から前面側に突出させた状態で上下に摺動可能に配設され、前パネルを施錠側に付勢するばねが取付けられ、前パネルを閉じると、前パネル用作動杆の鉤部が前パネルの縁部に設けた係止片に係止され、前パネルが施錠されるように構成される。
【０００７】
しかしながら、この施錠装置の前パネル施錠機構は、前パネル用作動杆に鉤部が突出するように一体成形され、前パネルを前面枠に対し閉じると、鉤部の傾斜部が係止片に当たって、前パネル用作動杆が鉤部と共に解錠方向に摺動し、その後ばね部材の付勢力により前パネル用作動杆が戻り、前パネルが施錠される構造のため、前パネル用作動杆の摺動抵抗が大きく、コイルばねの付勢力も大きくする必要があるため、前パネルを閉じる際にある程度大きな力を必要とする問題があった。
【０００８】
本発明は、上記の課題を解決するためになされたもので、構造が簡単で、軽い操作力で、前パネルの施錠と解錠を円滑に行うことができるパチンコ機の施錠装置を提供することを目的とする。
【０００９】
【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、取付板と支持板を有する縦長の基枠体と、基枠体の取付板に固定され、基枠体内に位置する錠軸にカム板を取り付けてなるシリンダ錠と、本体枠側に固定された受け金具に係止されて前面枠を施錠する鉤部材を有し、シリンダ錠によるカム板の一方向への回動に係合して鉤部材を解錠方向に動かす前面枠施錠機構と、ガラス枠側の係止片に係止されてガラス枠を施錠する鉤部材を有し、シリンダ錠によるカム板の他方向への回動に係合して鉤部材を解錠方向に動かすガラス枠施錠機構と、を備え、前面枠の内側に縦に取り付けられ、本体枠に対し前面枠を施錠し、前面枠に対しガラス枠を施錠するパチンコ機の施錠装置において、前パネル用鉤部材が基枠体の取付板から前方に突きして基枠体の下部に傾動可能に枢支され、基枠体内に前パネル用鉤部材を解錠方向にのみ動かすための前パネル用作動杆が摺動可能に配設され、前パネル用鉤部材には施錠側に付勢するコイルばねが掛止され、前パネル用作動杆の一部に操作部が設けられ、前面枠内の下部に開閉可能に取付けられた前パネル側に係止片が設けられ、前パネル用鉤部材が該係止片に係止されて前パネルが施錠されることを特徴とする。
【００１０】
ここで、請求項２のように、基枠体の支持板に前面枠施錠用の鉤部材を傾動可能に枢支し、鉤部材には施錠方向に付勢するコイルばねを掛止し、鉤部材を解錠方向にのみ動かすための前面枠施錠用の作動杆を支持板に沿って摺動可能に配設し、作動杆の一部にカム板が係合可能な係合孔を設けることができる。
【００１１】
また、請求項４のように、基枠体の支持板にガラス枠用鉤部材を傾動可能に枢支し、ガラス枠用鉤部材に施錠方向に付勢するコイルばねを取り付け、ガラス枠用鉤部材を解錠方向にのみ動かすためのガラス枠用作動杆を支持板に沿って摺動可能に配設し、ガラス枠用作動杆の一部にカム板が係合可能な係合孔を設けることができる。
【００１２】
【作用】
このような構成のパチンコ機の施錠装置では、前面枠を本体枠に対し閉じると、前面枠施錠用の鉤部材が本体枠側の受け金具に当り動いて係止され、施錠状態となる。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、カム板が前面枠施錠機構を動かして鉤部材を解錠方向に動かす。これにより、本体枠の受け金具と鉤部材との係合が外れ、前面枠は開放可能な状態となる。
【００１３】
一方、ガラス枠を閉じると、ガラス枠内の係止片が基枠体の取付板から突出したガラス枠用鉤部材に当り、これを動かして鉤部材に係止片が係止され、ガラス枠は施錠状態となる。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、カム板がガラス枠用作動杆を動かし、ガラス枠用作動杆がガラス枠用鉤部材を解錠方向に傾動させる。このガラス枠用鉤部材の傾動によって、ガラス枠の係止片と鉤部材の係合が外れ、ガラス枠は解錠される。
【００１４】
前パネルを開く場合、ガラス枠を開いた状態で、その開口部から前面枠内に手を入れ、施錠装置に取付けた前パネル用作動杆を、その操作部を持って押し下げる。このとき、前パネル用作動杆の係合部が前パネル用鉤部材の係合凸部に係合し、その前パネル用鉤部材を解錠方向に傾動させ、それによって、前パネル側に設けた係止片との係合が外れ、前パネルが解錠され、開かれる。一方、前パネルを閉じると、前パネル内の係止片が基枠体の取付板から突出した前パネル用鉤部材に当り、前パネル用鉤部材が傾動して係止片が係止され、前パネルは施錠状態となる。
【００１５】
このように、前パネルを施錠する際には、前パネルを前面枠に対し閉じると、前パネル用鉤部材のみが枢支ピンを軸に傾動して係止片に係止され、前パネルが施錠状態となるから、前パネルを軽く閉めるだけで、きわめて軽い操作力で確実に施錠することができ、また、解錠操作も軽く行なうことができる。
【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はその左側面図を、図３はその右側面図を、図４はその背面図を各々示し、図５はその分解図を示している。
【００１７】
１は取付板２と支持板３を略直角に曲折して一体成形してなる縦長の基枠体で、基枠体１の支持板３の上部と下部に、枢支部３ａ、３ｂがその部分のみを内側に入れるように分離して形成される。取付板２には複数の取付孔が穿設される。さらに、図５に示すように、支持板３の中間部には、後述の作動杆６を摺動可能にガイドするガイド部３ｃが、支持板３の一部を内側に切り起こして形成される。また、図１に示す如く、取付板２の上部と中間部の左側に、後述のガラス枠用鉤部材１１、１２を前方に突出させるためのスリット孔２ａ，２ｂが形成され、さらに、取付板２の下部の左側には、後述の前パネル用鉤部材１８，１９を前方に突出させるためのスリット孔２ｃ、２ｄが形成されている。
【００１８】
枢支部３ａ，３ｂには、各々鉤部材４、５が基枠体１の背面側を向けて、且つ下方に傾動（回動）可能に、枢支ピン４ａ，５ａにより枢支される。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有して、フック状に形成されている。さらに、鉤部材４，５の元部には、解錠時に後述の作動杆６の係合部６ｃ、６ｄが係合して解錠方向に押すための係合凸部４ｂ，５ｂが突設され、また、この係合凸部４ｂ，５ｂには、コイルばね９ａ，９ｂが施錠方向（上方）付勢するように掛止される。
【００１９】
この鉤部材４，５は、前面枠を本体枠に対し施錠するためのものであるが、施錠する際には、各鉤部材４，５が独立してコイルばね９ａ，９ｂの付勢力に抗して傾動するのみであるから、前面枠を閉じた際、非常に小さい力で軽く鉤部材を傾動させて施錠することができる。また、各鉤部材４，５が独立して傾動するから、針金などを前面枠の隙間に差し込んで行なわれる不正解錠に対しては、何れか一方の鉤部材を針金などで引っ掛けて、解錠方向に傾動させても、他方の鉤部材は解錠方向に動くことはないため、この種の不正解錠を防止することができる。
【００２０】
図５に示すように、作動杆６の上部と下部には、ガイド孔６ａ，６ｂが形成され、そのガイド孔６ａ，６ｂに、鉤部材４，５を枢支する枢支ピン４ａ，５ａが挿通され、基枠体１の内側に支持板３に沿って摺動可能に配設される作動杆６は、その枢支ピン４ａ，５ａとガイド孔６ａ，６ｂ及び上記ガイド部３ｃにより、上下にガイド摺動可能に支持されている。また、この作動杆６の上部寄りには後述のシリンダ錠７のカム板８が係合するための係合孔６ｅが形成される。また、この作動杆６にはコイルばね１５ａが掛止され、作動杆６を非解錠側に付勢している。
【００２１】
取付板２の上部寄りに、シリンダ錠７がその錠軸を孔から基枠体１の内側に挿入するように、ねじ又はかしめで固定される。シリンダ錠７の錠軸には第一係合部８ａと第二係合部８ｂを持つカム板８が固定される。図４の反時計方向にカム板８を回動させた場合、カム板の第一係合部８ａは作動杆６の係合孔６ｅに係合し、作動杆６を上方に摺動させ、鉤部材４、５の末部の係合凸部４ｂ、５ｂを上方に押して鉤部材４，５を下方に傾動させる。作動杆６と後述の前パネル用鉤部材１８間にコイルばね１５ａが掛けられ、作動杆６はコイルばね１５ａにより下側に付勢される。
【００２２】
さらに、取付板２のスリット孔２ａ、２ｂから前方に突き出すように、ガラス枠を施錠するガラス枠用鉤部材１１，１２が、基枠体１内の支持板３の上部と下部に、枢支ピン１１ａ，１２ａによって枢支されて取り付けられる。このガラス枠用鉤部材１１，１２は、下向きの係合凹部を持ったフック状に形成され、図５に示すように、元部に係合凸部１１ｂ、１２ｂが設けられ、後述のガラス枠用作動杆１０の係合部によってこの係合凸部１１ｂ、１２ｂが下方に押されることにより、このガラス枠用鉤部材１１，１２は解錠方向（上方）に傾動（回動）する。また、上部のガラス枠用鉤部材１１には、コイルばね１４ａが掛止され、このコイルばね１４ａにより鉤部材１１は下側施錠方向に付勢される。下部のガラス枠用鉤部材１２には、コイルばね１４ｂが掛止され、このコイルばね１４ｂにより鉤部材１２は下側施錠方向に付勢される。
【００２３】
作動杆６と支持板３の隙間に、ガラス枠を解錠するガラス枠用作動杆１０が摺動可能に配設される。ガラス枠用作動杆１０は、図５に示すように、帯状金属の上部と下部に、上記枢支ピン１１ａ，１２ａを挿通させるガイド孔１０ｃ、１０ｄを設け、さらに、その近傍に上記ガラス枠用鉤部材１１，１２を解錠方向に押すための係合部１０ａ，１０ｂを設けて形成される。また、このガラス枠用作動杆１０の中間部には、カム板８の第二係合部８ｂと係合可能な係合孔１０ｅが設けられている。
【００２４】
上下のガラス枠用鉤部材１１，１２は、独立して傾動可能であり、後述のガラス枠が閉じられてそこに設けた係止片が当たったとき、ガラス枠用作動杆１０の移動を伴わずに、上方に傾動して係止片に係止される。また、図２に示すように、支持板３の上部外側には、ガラス枠を解錠したとき、ガラス枠を開放側に押すための開放レバー１３が枢支ピン１３ａを介して枢支される。この開放レバー１３には、コイルばね１４ａがその下部に掛止され、開放レバー１３はコイルばね１４ａの付勢力により解錠されたガラス枠を前面に押し出すように作用する。
【００２５】
このガラス枠用鉤部材１１，１２においても、上記と同様に、各鉤部材１１，１２が独立してコイルばね１４ａ，１４ｂの付勢力に抗して傾動するのみであるから、ガラス枠を閉じた際、非常に小さい力で鉤部材１１，１２を傾動させて施錠することができる。また、各ガラス枠用鉤部材１１，１２が独立して傾動するから、針金などをガラス枠の隙間に差し込んで行なわれる不正解錠に対しては、何れか一方の鉤部材を針金などで引っ掛けて、解錠方向に傾動させても、他方の鉤部材は解錠方向に動くことはないため、不正解錠を防止することができる。
【００２６】
さらに、基枠体１内の下部には、図５、図６に示すように、後述の前パネル２８を施錠するための前パネル施錠機構が設けられる。前パネル施錠機構は、基枠体１の取付板２の下部に設けたスリット孔２ｃ、２ｄから前方に突出するように、２本の前パネル用鉤部材１８，１９を配設して構成され、前パネル用鉤部材１８，１９は支持板３の内側に枢支ピン１８ａ，１９ａを介して枢支される。また、支持板３の内側には解錠用に前パネル用作動杆１７が摺動可能に配設される。
【００２７】
図６に示すように、２本の前パネル用鉤部材１８，１９は、先端部がフック状に形成され、取付板２に設けたスリット孔から前方に突出する。前パネル用鉤部材１８，１９の元部には係合凸部１８ｂ、１９ｂが設けられ、上部の前パネル用鉤部材１８は、その係合凸部１８ｂにコイルばね１５ａが掛止され、上方の施錠側に付勢される。また、下部の前パネル用鉤部材１９は、その末端部にコイルばね１５ｂが掛止され、上方の施錠側に付勢される。
【００２８】
前パネル用作動杆１７には、前パネル用鉤部材１８，１９の元部の係合凸部１８ｂ、１９ｂに係合可能な係合部１７ｅ，１７ｆが設けられる。また、前パネル用作動杆１７には、２個のガイド孔１７ａ，１７ｂが形成され、このガイド孔１７ａ，１７ｂに上記の枢支ピン１８ａ，１９ａが挿通し、前パネル用作動杆１７はガイド孔１７ａ，１７ｂと枢支ピン１８ａ，１９ａを介して上下摺動可能に支持される。
【００２９】
前パネル用作動杆１７には、正面側に操作部１７ｃが設けられ、ガラス枠を開いた際、この操作部１７ｃが正面側に現れるようにしている。また、作動杆１７の中間部には、検出部１７ｄが突設され、図示しない検出器（近接スイッチなど）を対向して配設することにより、前パネルの開放動作を電気的に検出する。この前パネル用作動杆１７にはコイルばね１４ｂがその上部に掛止され、通常は上方に付勢される。操作部１７ｄを押し下げて、その付勢力に抗して前パネル用作動杆１７を下方に摺動させると、係合部１７ｅ，１７ｆが係合凸部１８ｂ、１９ｂに係合して前パネル用鉤部材１８，１９を下側の解錠方向に傾動させる。
【００３０】
このように、前パネル用鉤部材１８，１９は、上記と同様に、各鉤部材１８，１９が独立して傾動可能に枢支され、施錠時にはコイルばね１５ａ，１５ｂの付勢力に抗して傾動するのみであるから、前パネルを閉じた際、非常に小さい力で鉤部材を傾動させて、軽く施錠することができる。また、上記と同様に、各前パネル用鉤部材１８，１９が独立して傾動するから、針金などを前パネルの隙間に差し込んで行なわれる不正解錠に対しては、何れか一方の鉤部材を針金などで引っ掛けて、解錠方向に傾動させても、他方の鉤部材は解錠方向に動くことはないため、不正解錠を防止することができる。
【００３１】
このように構成された施錠装置は、図７、図８に示す如く、パチンコ機の本体枠２０に開閉可能に装着された前面枠２１の内側における矩形開口部の縁部に、シリンダ錠７の先端を前面に露出させ、鉤部材４、５を本体枠側に向けた姿勢で、取付板２を用いて縦に取付けられる。
【００３２】
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、ガラス枠２２が、前面枠２１の開口部に内に取付けられた金枠内にヒンジを開閉可能に取付けられ、そのガラス枠２２の自由端部内側に、ガラス枠用鉤部材１１，１２が係止可能な係止片２６、２７が設けられる。また、上皿などを設けた前パネル２８は、前面枠２１内の金枠の下部にヒンジを介して開閉可能取り付けられ、前パネル２８の自由端部内側に、前パネル用鉤部材１８，１９が係止可能な係止片２９，３０が設けられる。
【００３３】
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７に示すように、施錠装置の上下の鉤部材４、５が本体枠２０側の受け金具２４、２５に当って下方に傾動し、コイルばね９ａ，９ｂの付勢力により戻って係止され、施錠状態となる。このとき、鉤部材４，５は、各々が独立して傾動可能に枢支され、コイルばね９ａ，９ｂの付勢力に抗して傾動するのみであるから、前面枠２１を閉じた際、非常に小さい力で軽く鉤部材４，５を傾動させて施錠することができる。一方、施錠した状態では、各鉤部材４，５は独立して傾動するから、針金などを前面枠２１の隙間に差し込んで行なわれる不正解錠に対しては、何れか一方の鉤部材を針金などで引っ掛けて、解錠方向に傾動させても、他方の鉤部材は解錠方向に動くことはないため、この種の不正解錠を防止することができる。
【００３４】
前面枠２１を解錠する場合は、キーによってシリンダ錠７を回し、カム板８を図４の反時計方向に回転させると、カム板８の第一係合部８ａが作動杆６の係合孔６ａと係合してこれを上方へ摺動させる。このとき、作動杆６の係合部６ｃ、６ｄが鉤部材４、５の末端の係合凸部４ｂ、５ｂに係合して、鉤部材４，５を下方に傾動させる。この鉤部材４、５の傾動によって、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。
【００３５】
一方、ガラス枠２２を前面枠２１の金枠内に閉じると、ガラス枠２２内の係止片２６、２７がガラス枠用鉤部材１１，１２に当り、これを上方に傾動させながら閉じられ、コイルばね１４ａ，１４ｂの付勢力によりガラス枠用鉤部材１１，１２が水平位置に戻る。これにより、ガラス枠用鉤部材１１，１２に係止片２６、２７が係止され、ガラス枠２２は施錠状態となる。この場合も、ガラス枠用鉤部材１１，１２は、各々が独立してコイルばね１４ａ，１４ｂの付勢力に抗して傾動するのみであるから、ガラス枠２２を閉じた際、非常に小さい力で軽くガラス枠用鉤部材１１，１２を傾動させて施錠することができる。また、針金などによる不正解錠も防止することができる。
【００３６】
ガラス枠２２を解錠する場合は、図８に示すように、シリンダ錠７に差し込んだキーを左方向に回して、カム板８を図４時計方向へ回動させると、カム板８の第二係合部８ｂがガラス枠用作動杆１０の係合孔１０ｅと係合してこれを下方へ摺動させ、ガラス枠用作動杆１０の係合部１０ａ，１０ｂが鉤部材１１，１２の係合凸部１１ｂ、１２ｂに係合して、ガラス枠用鉤部材１１，１２を上方へ傾動させる。この動作によって、ガラス枠２２の係止片２６、２７とガラス枠用鉤部材１１，１２との係合が外れ、ガラス枠２２は開放される。
【００３７】
上皿等を前面に取付けた前パネル２８を開く場合、ガラス枠２２を開いた状態で、その開口部から内側に手を入れ、前パネル用作動杆１７の操作部１７ｃを持って押し下げる。これによって、前パネル用作動杆１７が下降し、その係合部１７ｅ，１７ｆが前パネル用鉤部材１８，１９の係合凸部１８ｂ、１９ｂに係合して、前パネル用鉤部材１８，１９が下方に傾動する。これにより、前パネル用鉤部材１８，１９と前パネル側の係止片２９、３０との係合が外れ、前パネル２８が解錠され、開かれる。
【００３８】
前パネル２８を閉じる場合、前パネル２８を前面枠２１内に閉じるように軽く押し込む。このとき、その係止片２９、３０が前パネル用鉤部材１８，１９の傾斜頭部に当たって、前パネル用鉤部材１８，１９を傾動させ、前パネル用鉤部材１８，１９に係止片２９、３０が係止され、前パネル２８は、施錠状態となる。この場合も、前パネル用鉤部材１８，１９は、各々が独立してコイルばね１５ａ，１５ｂの付勢力に抗して傾動するのみであるから、前パネル２８を閉じた際、非常に小さい力で軽く前パネル用鉤部材１８，１９を傾動させて施錠することができる。また、針金などによる不正解錠も防止することができる。
【００３９】
【発明の効果】
以上説明したように、本発明のパチンコ機の施錠装置によれば、前パネルを施錠する際、前パネルを前面枠に対し閉じると、前パネル用鉤部材のみがコイルばねの付勢力に抗して、枢支ピンを軸に傾動して係止片に係止され、前パネルが施錠状態となるから、前パネルを軽く閉めるだけで、きわめて軽い操作力で確実に施錠することができる。また、前パネルを解錠する際にも、前パネル用作動杆の操作部を軽く押し下げるだけで、解錠操作を容易に行なうことができる。
【００４０】
さらに、請求項２又は３の発明によれば、前面枠施錠用の鉤部材は、各々が独立して傾動可能に枢支され、施錠時にはコイルばねの付勢力に抗して傾動するのみであるから、前面枠を閉じた際、非常に小さい力で軽く鉤部材を傾動させて施錠することができる。さらに、請求項４又は５の発明によれば、ガラス枠用鉤部材は、各々が独立して傾動可能に枢支され、施錠時にはコイルばねの付勢力に抗して傾動するのみであるから、ガラス枠を閉じた際、非常に小さい力で軽くガラス枠用鉤部材を傾動させて施錠することができる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a locking device for a pachinko machine that locks a front frame of a pachinko machine to a main body frame, locks a glass frame to the front frame, and locks a front panel openably and closably mounted in the front frame. .
[0002]
[Prior art]
As a locking device for locking the front frame of the pachinko machine with respect to the main body frame, a connecting rod is slidably disposed inside a base frame body including an L-shaped cross-section mounting plate and a support plate, and an upper portion of the support plate. A hook member is connected to the connecting rod at the lower part and pivotally supported pivotally, and a cylinder lock is fixed to an intermediate portion of the mounting plate so that the lock shaft is inserted inward from a hole provided in the mounting plate. A locking device in which a cam plate engaged with a connecting rod is fixed to the tip of the lock is generally used (for example, see Japanese Utility Model Publication No. 57-8867).
[0003]
[Problems to be solved by the invention]
On the other hand, a metal frame is mounted in the front frame of the pachinko machine, a glass frame covering the panel surface is mounted on the upper part of the metal frame so as to be openable and closable, and a front panel for mounting an upper plate and the like is mounted on a lower part of the metal frame. Is mounted to be openable and closable. Normally, a locking member having a hook is slidably attached to an edge on the free end side of the front panel, and the hook of the locking member is provided on the metal frame side when the front panel is closed. The front panel is locked by a stop piece.
[0004]
When the front panel is opened, first, with the glass frame opened, a hand is inserted into the opening from the front side, and the locking member provided on the front panel is moved by hand, whereby the locking piece is opened. And the front panel is unlocked.
[0005]
However, the front panel is usually formed of a relatively thin metal plate, and the locking member is also formed of a similar metal plate. Therefore, when the locking member is pressed down during unlocking, the front panel itself is deformed. In some cases, the deformation deteriorates the positional relationship between the hooks of the locking member and the locking pieces, causing a problem that locking and unlocking of the front panel cannot be performed smoothly.
[0006]
Therefore, the present inventors have proposed a locking device provided with a front panel locking mechanism in JP-A-10-66775.

BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 is a front view of the locking device, FIG. 2 is a left side view thereof, FIG. 3 is a right side view thereof, FIG. 4 is a rear view thereof, and FIG. 5 is an exploded view thereof.
[0017]
Reference numeral 1 denotes a vertically long base frame which is formed by bending the mounting plate 2 and the support plate 3 at a substantially right angle and integrally forming the base plate 1. The support portions 3a and 3b are provided on the upper and lower portions of the support plate 3 of the base frame 1. It is formed separately so that only the inside is inserted. A plurality of mounting holes are formed in the mounting plate 2. Further, as shown in FIG. 5, a guide portion 3c for slidably guiding an operation rod 6 to be described later is formed at an intermediate portion of the support plate 3 by cutting and raising a part of the support plate 3 inward. . As shown in FIG. 1, slit holes 2a and 2b for projecting glass frame hook members 11 and 12 to be described later are formed on the upper side of the mounting plate 2 and on the left side of the intermediate portion. On the left side of the lower part of 2, there are formed slit holes 2c, 2d for projecting front panel hook members 18, 19 described later forward.
[0018]
Hook members 4 and 5 are pivotally supported by the pivot pins 4a and 5a at the pivot portions 3a and 3b, respectively, so that the hook members 4 and 5 can be tilted (turned) downward toward the back side of the base frame 1. Each of the hook members 4 and 5 has a triangular head and an engagement recess at an intermediate portion thereof, and is formed in a hook shape. Further, engaging protrusions 4b and 5b are provided at the bases of the hook members 4 and 5 to engage with engaging portions 6c and 6d of the operating rod 6 to be pushed in the unlocking direction during unlocking. Further, the coil springs 9a, 9b are hooked on the engaging projections 4b, 5b so as to urge the locking direction (upward).
[0019]
The hook members 4, 5 are for locking the front frame to the main body frame. When locking, each of the hook members 4, 5 independently resists the urging force of the coil springs 9a, 9b. When the front frame is closed, the hook member can be tilted lightly with a very small force to lock. In addition, since each of the hook members 4 and 5 tilts independently, in order to prevent unauthorized unlocking performed by inserting a wire or the like into a gap in the front frame, one of the hook members is hooked with a wire or the like to unlock. Even if it is tilted in the locking direction, the other hook member does not move in the unlocking direction, so this type of unauthorized unlocking can be prevented.
[0020]
As shown in FIG. 5, guide holes 6a, 6b are formed in the upper and lower portions of the operating rod 6, and pivot pins 4a, 5a for pivotally supporting the hook members 4, 5 are formed in the guide holes 6a, 6b. The operating rod 6, which is inserted and slidably disposed inside the base frame 1 along the support plate 3, is vertically moved by the pivot pins 4a, 5a, the guide holes 6a, 6b and the guide portion 3c. The guide is slidably supported. Further, an engagement hole 6e for engaging a cam plate 8 of a cylinder lock 7, which will be described later, is formed near the upper portion of the operating rod 6. A coil spring 15a is hooked on the operating rod 6 to urge the operating rod 6 to the unlocking side.
[0021]
Near the upper part of the mounting plate 2, the cylinder lock 7 is fixed by screws or caulking so that the lock shaft is inserted into the inside of the base frame 1 from the hole. A cam plate 8 having a first engaging portion 8a and a second engaging portion 8b is fixed to the lock shaft of the cylinder lock 7. When the cam plate 8 is rotated counterclockwise in FIG. 4, the first engaging portion 8a of the cam plate engages with the engaging hole 6e of the operating rod 6, and slides the operating rod 6 upward. The engaging projections 4b, 5b at the ends of the hook members 4, 5 are pushed upward to tilt the hook members 4, 5 downward. A coil spring 15a is hung between the operating rod 6 and a front panel hook member 18, which will be described later, and the operating rod 6 is urged downward by the coil spring 15a.
[0022]
Further, glass frame hook members 11 and 12 for locking the glass frame are projected on the upper and lower portions of the support plate 3 in the base frame 1 so as to protrude forward from the slit holes 2 a and 2 b of the mounting plate 2. It is pivotally mounted by the pins 11a and 12a. The hook members 11 and 12 for glass frames are formed in a hook shape having downwardly engaging recesses, and as shown in FIG. When the engaging projections 11b and 12b are pushed downward by the engaging portion of the operating rod 10, the glass frame hook members 11 and 12 are tilted (turned) in the unlocking direction (upward). A coil spring 14a is hung on the upper glass frame hook member 11, and the hook member 11 is urged in the lower locking direction by the coil spring 14a. A coil spring 14b is hooked on the lower glass frame hook member 12, and the hook member 12 is urged in the lower locking direction by the coil spring 14b.
[0023]
A glass frame operating rod 10 for unlocking the glass frame is slidably disposed in the gap between the operating rod 6 and the support plate 3. As shown in FIG. 5, the operating rod 10 for a glass frame is provided with guide holes 10c and 10d for inserting the pivot pins 11a and 12a at the upper and lower portions of the band-shaped metal. It is formed by providing engaging portions 10a and 10b for pushing the hook members 11 and 12 in the unlocking direction. An engagement hole 10e engageable with the second engagement portion 8b of the cam plate 8 is provided at an intermediate portion of the glass frame operating rod 10.
[0024]
The upper and lower glass frame hook members 11 and 12 can be tilted independently, and when the below-described glass frame is closed and a locking piece provided there comes in contact, the glass frame operating rod 10 moves. Instead, it is tilted upward and locked by the locking pieces. As shown in FIG. 2, an opening lever 13 for pushing the glass frame to the open side when the glass frame is unlocked is pivotally supported via a pivot pin 13a on the upper outside of the support plate 3. . A coil spring 14a is hung on the lower part of the opening lever 13, and the opening lever 13 acts to push the unlocked glass frame to the front by the urging force of the coil spring 14a.
[0025]
Also in the hook members 11 and 12 for the glass frames, the hook members 11 and 12 independently tilt only against the urging force of the coil springs 14a and 14b, similarly to the above, so that the glass frames are closed. In this case, the hook members 11, 12 can be tilted and locked with a very small force. Further, since each of the glass frame hook members 11 and 12 tilts independently, one of the hook members is hooked with a wire or the like against unauthorized unlocking performed by inserting a wire or the like into the gap of the glass frame. Thus, even if the other hook member is tilted in the unlocking direction, the other hook member does not move in the unlocking direction, so that unauthorized unlocking can be prevented.
[0026]
Further, a lower part of the base frame 1 is provided with a front panel locking mechanism for locking a front panel 28 described later, as shown in FIGS. The front panel locking mechanism is configured by arranging two front panel hook members 18 and 19 so as to protrude forward from slit holes 2c and 2d provided in a lower portion of the mounting plate 2 of the base frame body 1. The front panel hook members 18, 19 are pivotally supported inside the support plate 3 via pivot pins 18a, 19a. A front panel operating rod 17 is slidably disposed inside the support plate 3 for unlocking.
[0027]
As shown in FIG. 6, the two front panel hook members 18 and 19 have hook-like tips, and protrude forward from slit holes provided in the mounting plate 2. Engagement projections 18b, 19b are provided at the bases of the front panel hook members 18, 19, and the coil spring 15a is hooked on the engagement projection 18b of the upper front panel hook member 18, and Is biased to the locking side. In addition, the lower front panel hook member 19 has a coil spring 15b hooked at the end thereof, and is urged upward to the locking side.
[0028]
The front panel operating rod 17 is provided with engaging portions 17e, 17f which can be engaged with the engaging convex portions 18b, 19b of the front portions of the front panel hook members 18,19. The front panel operating rod 17 is formed with two guide holes 17a and 17b. The pivot pins 18a and 19a are inserted into the guide holes 17a and 17b. It is vertically slidably supported via the holes 17a, 17b and the pivot pins 18a, 19a.
[0029]
The front panel operating rod 17 is provided with an operation section 17c on the front side, and when the glass frame is opened, this operation section 17c appears on the front side. A detecting portion 17d is protrudingly provided at an intermediate portion of the operating rod 17, and a detector (not shown) (such as a proximity switch) is disposed so as to oppose to electrically detect opening operation of the front panel. A coil spring 14b is hooked on an upper part of the front panel operating rod 17, and is normally urged upward. When the operating portion 17d is pressed down and the front panel operating rod 17 is slid downward against the urging force, the engaging portions 17e and 17f engage with the engaging projections 18b and 19b to engage the front panel operating rod 17d. The hook members 18 and 19 are tilted in the lower unlocking direction.
[0030]
As described above, the front panel hook members 18 and 19 are pivotally supported so that the hook members 18 and 19 can be tilted independently, and against the urging force of the coil springs 15a and 15b when locked. Since only the tilting is performed, when the front panel is closed, the hook member can be tilted with a very small force to lightly lock. Further, similarly to the above, since the front panel hook members 18 and 19 are independently tilted, any one of the hook members against unauthorized unlocking performed by inserting a wire or the like into the gap of the front panel. Is hooked with a wire or the like and tilted in the unlocking direction, the other hook member does not move in the unlocking direction, so that unauthorized unlocking can be prevented.
[0031]
As shown in FIGS. 7 and 8, the locking device configured as described above has a cylinder lock 7 on the edge of a rectangular opening inside a front frame 21 that is openably and closably mounted on a main frame 20 of a pachinko machine. It is attached vertically using the attachment plate 2 with the tips exposed to the front and the hook members 4, 5 facing the body frame side.
[0032]
On the other hand, receiving metal fittings 24 and 25 are fixed to upper and lower positions corresponding to the hook members 4 and 5 inside the main body frame 20. Further, a glass frame 22 is mounted in a metal frame mounted in an opening of the front frame 21 so as to open and close a hinge, and inside the free end of the glass frame 22, hook members 11 and 12 for glass frames are provided. Locking pieces 26 and 27 are provided. A front panel 28 provided with an upper plate and the like is attached to the lower part of the metal frame in the front frame 21 via a hinge so as to be openable and closable, and inside the free end of the front panel 28, front panel hook members 18 and 19 are provided. Locking pieces 29 and 30 are provided.
[0033]
When the front frame 21 of the pachinko machine is closed with respect to the main body frame 20, the upper and lower hook members 4, 5 of the locking device are tilted downward against the metal fittings 24, 25 on the main body frame 20, as shown in FIG. Then, it is returned and locked by the urging force of the coil springs 9a and 9b, and becomes locked. At this time, the hook members 4 and 5 are pivotally supported independently of each other and can only tilt against the urging force of the coil springs 9a and 9b. The hook members 4 and 5 can be locked by slightly tilting them with a small force. On the other hand, in the locked state, each of the hook members 4 and 5 tilts independently. Therefore, in the case of unauthorized unlocking performed by inserting a wire or the like into the gap of the front frame 21, one of the hook members is connected to the wire. Even if it is hooked and tilted in the unlocking direction, the other hook member does not move in the unlocking direction, so this type of unauthorized unlocking can be prevented.
[0034]
When unlocking the front frame 21, the cylinder lock 7 is turned by a key and the cam plate 8 is rotated in the counterclockwise direction in FIG. 4 so that the first engagement portion 8 a of the cam plate 8 engages with the operating rod 6. It engages with the hole 6a and slides it upward. At this time, the engaging portions 6c and 6d of the operating rod 6 are engaged with the engaging projections 4b and 5b at the ends of the hook members 4 and 5 to tilt the hook members 4 and 5 downward. Due to the tilting of the hook members 4 and 5, the engagement of the main frame with the receiving fittings 24 and 25 is released, and the front frame 21 can be opened.
[0035]
On the other hand, when the glass frame 22 is closed in the metal frame of the front frame 21, the locking pieces 26 and 27 in the glass frame 22 hit the hook members 11 and 12 for the glass frame and are closed while tilting them upward. The hook members 11 and 12 for glass frames return to the horizontal position by the urging force of the coil springs 14a and 14b. Thereby, the locking pieces 26 and 27 are locked to the hook members 11 and 12 for the glass frame, and the glass frame 22 is in a locked state. Also in this case, since the glass frame hook members 11 and 12 only tilt independently against the urging force of the coil springs 14a and 14b, when the glass frame 22 is closed, a very small force is applied. Thus, the hook members 11 and 12 for the glass frame can be lightly tilted and locked. Also, unauthorized unlocking by wire or the like can be prevented.
[0036]
When unlocking the glass frame 22, as shown in FIG. 8, the key inserted into the cylinder lock 7 is turned counterclockwise to rotate the cam plate 8 clockwise in FIG. The two engaging portions 8b are engaged with the engaging holes 10e of the glass frame operating rod 10 and slid downward, and the engaging portions 10a and 10b of the glass frame operating rod 10 The hook members 11 and 12 for glass frames are tilted upward by engaging with the engaging projections 11b and 12b. By this operation, the engagement pieces 26 and 27 of the glass frame 22 are disengaged from the hook members 11 and 12 for the glass frame, and the glass frame 22 is opened.
[0037]
When opening the front panel 28 with the upper plate or the like attached to the front, with the glass frame 22 opened, put a hand inward from the opening and hold down the operating portion 17c of the operating lever 17 for the front panel and push it down. As a result, the front panel operating rod 17 is lowered, and the engaging portions 17e, 17f engage with the engaging projections 18b, 19b of the front panel hook members 18, 19, and the front panel hook members 18, 19 are engaged. 19 tilts downward. As a result, the engagement between the front panel hook members 18 and 19 and the front panel side locking pieces 29 and 30 is released, and the front panel 28 is unlocked and opened.
[0038]
When closing the front panel 28, the front panel 28 is lightly pushed into the front frame 21 so as to be closed. At this time, the locking pieces 29, 30 hit the inclined heads of the front panel hook members 18, 19, and the front panel hook members 18, 19 are tilted, and the front panel hook members 18, 19 are attached to the front panel hook members 18, 19. , 30 are locked, and the front panel 28 is locked. Also in this case, since the front panel hook members 18 and 19 only tilt independently against the urging force of the coil springs 15a and 15b, when the front panel 28 is closed, a very small force is applied. Thus, the front panel hook members 18 and 19 can be tilted and locked. Also, unauthorized unlocking by wire or the like can be prevented.
[0039]
【The invention's effect】
As described above, according to the pachinko machine locking apparatus of the present invention, when locking the front panel, when the front panel is closed with respect to the front frame, only the front panel hook member resists the urging force of the coil spring. Thus, the pivot pin is tilted about the axis to be locked by the locking piece, and the front panel is in a locked state. Therefore, just by closing the front panel lightly, it is possible to reliably lock with a very light operating force. Also, when unlocking the front panel, the unlocking operation can be easily performed only by lightly pressing down the operating portion of the operating rod for the front panel.
[0040]
Further, according to the second or third aspect of the present invention, each of the hook members for locking the front frame is independently pivotally supported so as to be tiltable, and only tilts against the urging force of the coil spring when locking. Therefore, when the front frame is closed, the hook member can be tilted lightly with a very small force to lock. Further, according to the invention of claim 4 or 5, since the hook members for the glass frame are each pivotally supported independently so as to be tiltable, and when locked, they only tilt against the urging force of the coil spring. When the glass frame is closed, the lock member can be locked by tilting the hook member for the glass frame lightly with a very small force.
