Description

【０００１】
【発明の属する技術分野】
本発明は、スロットマシン、パチンコ機などのゲーム機の前扉（前枠）を筐体（本体枠）に対し開閉自在に取り付ける着脱式のゲーム機用蝶番に関する。
【０００２】
【従来の技術】
従来、パチンコ機などのゲーム機の前枠を本体枠に対し開閉自在に取り付ける蝶番として、上部に取り付けられる上部蝶番と下部に取り付けられる下部蝶番からなる構造の蝶番が、通常使用されている。この蝶番は、上部蝶番、下部蝶番共に固定部と可動部とに分かれて形成され、ピンと軸受部の嵌合により可動部側が固定部側に対し回動可能に支持される。つまり、上部蝶番の固定部は本体枠の上角部に固定され、上部蝶番の可動部は前枠の上角部に固定され、下部蝶番の固定部は本体枠の下角部に固定され、下部蝶番の可動部は前枠の下角部に固定される。そして、前枠を本体枠に対し取り付ける場合、前枠を持ってその下部蝶番の可動部を本体枠側の固定部にピンと軸受の嵌合により嵌め込み、同時に、その上部蝶番の可動部を本体枠側の固定部にピンと軸受の嵌合により嵌め込む。
【０００３】
【発明が解決しようとする課題】
従って、上記のように、前枠を本体枠に対し装着する際には、上角部と下角部に設けた両蝶番のピンと軸受を上下同時に嵌め合わせて行なう必要があり、加えて、ゲーム機の前枠には、各種の機械機器、電気機器が数多く取り付けられているから、前枠の重量は非常に重い。また、これらの前枠は、作業者の手作業により本体枠側に装着されるため、このような前枠の取り付け作業は、かなり難しく、労力を必要とし、ピンと軸受の嵌合が良好にできない場合には、蝶番や他の部材を傷つけてしまう問題があった。
【０００４】
本発明は、上記の点に鑑みてなされたもので、ゲーム機の前扉と筐体に着脱可能に固定される蝶番の可動部材と固定部材を容易に嵌合して組み付けることができるゲーム機用蝶番を提供することを目的とする。
【０００５】
【課題を解決するための手段】
上記目的を達成するために、本発明のゲーム機用蝶番は、ゲーム機の筐体側に固定され、上部に下向きの上ピンを設け、下部に上向きの下ピンを設けた固定部材と、
該固定部材の上部の該上ピンに嵌合する軸受部材を上部に設け、下部の該下ピンに嵌合する軸受孔を下部に設けて、該固定部材に対し回動可能に支持され、該ゲーム機の前扉側に取り付けられる可動部材と、
を備えたゲーム機用蝶番において、
該固定部材は縦長の固定取付板の上部に上突出支持部を略水平に設け該固定取付板の下部に下突出支持部を略水平に設けて形成され、
前記上ピン及び下ピンが該固定取付板の位置より左側前方に位置するように、該上突出支持部の先端部に該上ピンが下向きに突設されると共に、該固定部材の下部に設けた下突出支持部に該下ピンが上向きに突設され、
該可動部材は縦長の可動取付板の上部に上突出板部を水平状に設け該可動取付板の下部に下突出板部を水平状に設けて形成され、該上突出支持部は平面を略コ字状とした形状に形成されると共に前方に突出して設けられ、
該可動部材の上部に設けた上突出板部上に該固定部材側の前記上ピンを軸支する前記軸受部材が設けられると共に、該軸受部材の軸受孔の一部を開閉する回動部材が回動可能に取り付けられ、
該可動部材の下部に設けた下突出板部上には該固定部材側の前記下ピンを軸支する前記軸受孔が設けられ、
該固定取付板及び該可動取付板は共に該筐体と該前扉の内側に取り付けられ、該可動部材の該上突出板部と該下突出板部は該前扉の内側に配置され、
前記固定部材の固定取付板の縁部に沿って当接壁部が設けられ、前記可動部材の可動取付板には該可動部材の閉動作時に該固定部材側の該当接壁部に当接する閉鎖壁部が縁部に沿って設けられ、
該固定部材に該可動部材を組み付ける際、該可動部材側の該下突出板部の該軸受孔を該固定部材側の該下突出支持部上の該下ピンに嵌合した状態で、該固定部材側の該上ピンを該可動部材側の該上突出板部の該軸受部材の軸受孔に、該回動部材を開口側に回動させながら嵌合させることを特徴とする。
【０００６】
ここで、上記構成の蝶番においては、請求項２のように、回動部材に上ピンをガイドするピン案内部を設け、軸受部材の軸受孔を閉じる側に回動部材を付勢するばね部材を設け、上ピンを軸受孔に挿入する際、上ピンによって回動部材を回動させて軸受部材の軸受孔に挿入するように構成することができる。
【０００８】
【作用】
このような構成のゲーム機用蝶番は、ゲーム機の筐体の内側に蝶番の固定部材が固定され、前扉の内側に蝶番の可動部材が固定される。
【０００９】
前扉を筐体に対し開閉可能に装着する場合、先ず、前扉を持って可動部材の下突出板部の軸受孔を、筐体側の固定部材の下突出支持部の下ピンに嵌め込む。
【００１０】
次に、その下突出支持部の下ピンを支点にして前扉を少し傾けながら、可動部材の上突出板部の軸受部材を、その固定部材の上突出支持部の上ピンの近傍に近づけ、その上ピンを上突出板部上に進入させ、回動部材を上ピンで押すように動かす。これにより、上ピンは、回動部材の回動によって開口した軸受部材の軸受孔内に滑るように進入する。そして、上ピンが軸受孔内に嵌入した後、回動部材がばね部材の付勢力で元の位置に戻り、軸受孔の切欠き開口部が閉鎖され、上ピンは軸受部材の軸受孔に良好に嵌合し、可動部材は固定部材に対し回動可能に支持される。
【００１１】
このように、可動部材の下軸受孔を固定部材側の下ピンに嵌め、次に下ピンを支点にして前扉を少し水平方向に傾けながら、上突出板部上の軸受部材を、固定部材の上ピンに近づけ、上ピンによって回動部材を回動させながら、軸受部材の軸受孔を開口させ、そこに上ピンを滑り込ませるように嵌合させるため、従来のように、上部蝶番と下部蝶番のピンと軸受部の嵌合を、前枠を持ちながら同時に行なう必要がなく、重量のある前扉を非常に簡単に、筐体に対し蝶番を介して取り付けることができる。さらに、上突出支持部は、平面を略コ字状とした形状に形成され且つ前方に突出して設けられ、その上突出支持部の先端部に上ピンが下向きに突設されるから、上突出支持部の上ピン及びそれに対応した下ピンつまり蝶番の軸ピンの位置を、固定部材の取付面より左側前方に離して位置させることができ、これにより、スロットマシンのように筐体と前扉の内側に蝶番が取り付けられ且つ厚さの厚い前扉を設けた場合でも、筐体側の前面の蝶番装着部分を凹状に切り欠く必要がなく、閉鎖時の筐体と前扉の隙間を最小にすることができる。
【００１２】
また、固定取付板の縁部に沿って当接壁部を設け、可動取付板には可動部材の閉動作時に固定部材側の当接壁部に当接可能な閉鎖壁部を設ければ、前扉を閉じたとき、可動部材の閉鎖壁部が固定側の当接壁部に当接し、筐体と前扉との間に生じやすい隙間を、蝶番によって閉鎖し、ゲーム機の前扉の隙間から針金などを差し込んで行なわれる不正行為を防止することができる。
【００１３】
【発明の実施の形態】
以下、本発明の実施の形態を図面に基づいて説明する。図１、図２はスロットマシンなどのゲーム機の筐体側に固定される蝶番の固定部材１を示している。この固定部材１は、板状の縦長の固定取付板４の上端に上突出支持部２が略水平に形成され、固定取付板４の下端に下突出支持部６が略水平に形成され、上突出支持部２の先端の下面に上ピン３が下向きに突設され、下突出支持部６の先端の上面に下ピン７が上向きに突設されて構成される。
【００１４】
図２の平面図に示すように、上突出支持部２と下突出支持部６は、鋼板を略コ字状に裁断して形成され、その先端に上ピン３と下ピン７を固定することにより、上ピン３と下ピン７つまり蝶番の軸心位置を、できるだけ筐体の左側面寄りに設定している。勿論、上ピン３と下ピン７の軸心位置は、縦長の固定取付板４の平面に沿った１本の軸線上に一致する。また、上突出支持部２においては、後述の可動部材１０側の上突出板部１２のストッパ１２ａが回動可能な空間を作っている。また、下突出支持部６には、可動部材１０が開動作をしたとき、その回動端で可動部材１０の下突出板部１６に当接するストッパ６ａが上向きに突設されている。このストッパ６ａは、可動部材１０の最大開放角度を設定し、ここでは略９０度としている。
【００１５】
さらに、固定取付板４の正面側の縁部には、当接壁部５が縁部を正面側に略直角に曲げるように形成され、この当接壁部５は、後述の可動部材１０の可動取付板１１の閉鎖壁部１８に対し、蝶番の閉動作時に当接し、固定部材と可動部材間の隙間をなくし所定の位置関係で閉鎖状態とする。
【００１６】
可動部材１０は、図４〜図６に示すように、縦長で板状の可動取付板１１の上端に上突出板部１２を水平状に設け、可動取付板１１の下端に下突出板部１６を水平状に設け、上突出板部１２上には軸受部材１３を固定し、下突出板部１６には下軸受孔１７を穿設して構成される。上突出板部１２上に固定される軸受部材１３は、固定部材１側の上ピン３を嵌入させるために軸受孔１４を設けて形成され、図５に示すように、軸受孔１４はその一部の側壁が切り欠かれ、その切欠き開口部から上ピン３を嵌めこみ可能としている。
【００１７】
下軸受孔１７と軸受部材１３の軸受孔１４の軸心位置は、可動取付板１１の平面に沿った１本の軸線上に一致するように形成され、且つこの軸心位置つまり蝶番の軸位置は、可動部材１０の正面寄りで左側面寄りの角部に位置するように形成される。また、可動取付板１１の縁部には、固定部材１に対し可動部材１０を閉じる方向に回動させたとき、所定の回動位置で停止し、縁部を正面側に曲げた板部として、閉鎖壁部１８が形成され、
さらに、軸受孔１４の切欠き開口部を閉じるために、回動部材１５が回動軸１５ａを軸にして回動可能に軸支される。回動部材１５は、軸受孔１４の切欠き部を閉鎖する円弧部を有するとともに、その円弧部に続いて上ピン３を案内するためのピン案内部１５ｃを凹部状に設けて形成される。
【００１８】
さらに、手動操作により容易に回動できるように、回動部材１５の端部にはレバー操作部１５ｄが設けられている。回動部材１５上に長孔１５ｅが形成され、その長孔１５ｅにピンが嵌挿され、回動部材１５の回動範囲を所定の角度範囲に制限している。また、回動部材１５にはばね部材１５ｂが装着され、ばね部材１５ｂは回動部材１５を図５の時計方向に付勢している。回動部材１５のピン案内部１５ｃは、上ピン３の移動力を受けて、回動部材１５が図５の反時計方向に回動し、軸受孔１４の切欠き部を開放するように形成される。
【００１９】
また、図９に示すように、固定部材１側の上ピンを可動部材１０側の軸受孔１４に挿入する場合、上突出板部１２の背面側から上ピンを進入させ、回動部材１５のピン案内部１５を押して、前方の軸受部材１３内に移動するように、上突出板部１２上に上ピンの導入路が形成されている。
【００２０】
このように構成された蝶番の固定部材１は、その固定取付板４に設けた取付孔と固定ねじを使用して、図７〜図１２に示すように、ゲーム機の筐体２０の内側の左側面に、その上突出支持部２と下突出支持部６を前方に出して固定される。
【００２１】
一方、蝶番の可動部材１０は、ゲーム機の前扉２１の内側の左側面に、その可動取付板１１とそこに穿設した取付孔及び固定ねじを用いて、その上突出板部１２と下突出板部１６を前扉２１の内側に入れた状態で、縦に固定される。
【００２２】
前扉２１を筐体２０に対し開閉可能に装着する場合、先ず、前扉２１を持ち筐体２０に対し約４５度開いた状態で、可動部材１０の下突出板部１６の下軸受孔１７を、筐体２０側の固定部材１の下突出支持部６の下ピン７に嵌め込む。下軸受孔１７は鋼板に穿設した孔であり、ピンと孔の嵌め合いには多少の間隙があるため、前扉２１は多少傾動可能である。
【００２３】
次に、その下突出支持部６の下ピン７を支点にして前扉２１を少し傾けながら、可動部材１０の上突出板部１２の軸受部材１３を、その固定部材１の上突出支持部２の上ピン３の近傍に近づけ、その上ピン３を図９のように、上突出板部１２上の進入路に進入させ、回動部材１５のピン案内部１５ｃを上ピン３で押すように動かす。これにより、上ピン３は、回動部材１５を図９のようにばね部材１５ｂの付勢力に抗して回動させて、軸受孔１４を開くと共に、回動部材１５の回動によって開口した軸受孔１４内に滑るように進入する。そして、上ピン３が軸受孔１４内に嵌入した後、回動部材１５がばね部材１５ｂの付勢力で元の位置に戻り、軸受孔１４の切欠き開口部が閉鎖され、上ピン３は軸受部材１３の軸受孔１４に嵌合し、可動部材１０は固定部材１に対し回動可能に正常位置に支持される状態となる。
【００２４】
このように、先ず、可動部材１０の下軸受孔１７を固定部材１側の下ピン７に嵌め、次に下ピン７を支点にして前扉２１を少し水平方向に傾けながら、上突出板部１２上の軸受部材１３を、固定部材１の上ピン３に近づけ、上ピン３によって回動部材１５を回動させながら、軸受部材１３の軸受孔１４に上ピン３を滑り込ませるように嵌合させるため、従来のように、上部蝶番と下部蝶番のピンと軸受部の嵌合を、前枠を持ちながら同時に行なう必要がなく、重量のある前扉２１を非常に簡単に、筐体２０に対し蝶番を介して取り付けることができる。
【００２５】
蝶番を介して開閉可能に取り付けられた前扉２１は、図１１に示すように、その閉鎖位置では、固定部材１の当接壁部５に可動部材１０の閉鎖壁部１８が当接して所定の閉鎖位置を確保し、その当接によって筐体２０と前扉２１間の隙間を塞ぐこともできる。一方、前扉２１を開放側に回動したときには、図１２のように、可動部材１０の上突出板部１２のストッパ１２ａが固定部材１の上突出支持部２の側部に当接した状態が回動端となって、この例では約９０度の最大開放角度が設定される。
【００２６】
また、固定部材１の上突出支持部２の上ピン３及び下突出支持部６の下ピン７の位置が、固定部材１の取付面より左側に寄って位置し、つまり筐体２０の蝶番を取り付ける側の側壁の外側面近傍に蝶番の軸ピンが位置するため、筐体２０側の前面の蝶番装着部分を凹状に切り欠かなくても、前扉２１を良好に開閉することができ、筐体２０に対し前扉２１を最小の隙間で開閉することができる。
【００２７】
前扉２１を筐体２０から外す場合、つまり蝶番の可動部材１０を固定部材１より外す場合、前扉２１を筐体２０の前方に開いた状態で、可動部材１０の上突出板部１２上の回動部材１５を図９の位置まで回動させれば、上ピン３が軸受部材１３の軸受孔１４から容易に外れ、簡単に前扉２１つまり蝶番の可動部材１０を外すことができる。回動部材１５を回して軸受孔１４を開放しない状態では、可動部材１０の上突出板部１２が固定部材１の上突出支持部２の下面に当り、前扉２１を持ち上げることができないから、前扉２１を外すことはできない。
【００２８】
図１３〜図２５は他の実施形態のゲーム機用蝶番を示し、その図１３、図１４はゲーム機の筐体側に固定される蝶番の固定部材３１を示している。この固定部材３１は、板状の縦長の固定取付板３４の上部に上突出支持部３２が略水平に突き出すように形成され、固定取付板３４の下端に水平板状の下突出支持部３６が段差をつけて略水平に形成され、上突出支持部３２の先端の下面に上ピン３３が下向きに突設され、下突出支持部３６の一端の上面に下ピン３７が上向きに突設されて構成される。
【００２９】
図１５の平面図に示すように、上突出支持部３２は、鋼板を略コ字状に裁断して形成され、その前方左側に突き出した先端部に上ピン３３が固定される。また、下突出支持部３６は鋼板を略矩形に裁断して形成され、その一端の角部つまり前方の突き出した部分の左側に、下ピン７が固定される。これにより、上ピン３３と下ピン３７つまり蝶番の軸心位置を、できるだけ筐体の左側面寄りに設定している。勿論、上ピン３３と下ピン３７の軸心位置は、縦長の固定取付板３４の平面に沿った１本の軸線上に一致している。
【００３０】
さらに、固定取付板３４の正面側の縁部には、当接壁部３５が縁部を正面側に略直角に曲げるように形成され、この当接壁部３５は、後述の可動部材４０の可動取付板４１の閉鎖壁部４８に対し、蝶番の閉動作時に当接し、固定部材と可動部材間の隙間をなくし所定の位置関係で閉鎖状態とする。また、特に、当接壁部３５は、筐体に固定されたとき、筐体の左側壁部の縁部を覆うように左側に曲折され、筐体の左側壁部の角部で正面側に略直角に曲げられ、筐体の左側壁部の外面近傍で隙間を閉鎖するようにしている。
【００３１】
また、この当接壁部３５は、上ピン３３を設けた上突出支持部３２の位置より上方に突出して上突出当接壁部３５ａを形成している。この上突出当接壁部３５ａは、蝶番が筐体に固定されたとき、筐体の上部に隙間が生じないように、そこを塞ぐために形成され、後述の可動部材４０の閉鎖壁部４８の上部にも、この上突出当接壁部３５ａに対応した部分として、上突出閉鎖壁部４８ａが、前扉の閉鎖時に上突出当接壁部３５ａと当接可能に設けられる。
【００３２】
可動部材４０は、図１７〜図１９に示すように、縦長で板状の可動取付板４１の上部に上突出板部４２を水平状に設け、可動取付板４１の下端に下突出板部４６を水平状に設け、上突出板部４２上には軸受部材４３を固定し、下突出板部４６には下軸受孔４７を穿設して構成される。上突出板部４２上に固定される軸受部材４３は、上記固定部材３１側の上ピン３３を嵌入させるために軸受孔４４を設けて形成され、図１９に示すように、軸受孔４４はその一部の側壁が切り欠かれ、その切欠き開口部から上ピン３３を嵌めこみ可能としている。
【００３３】
下軸受孔４７と軸受部材４３の軸受孔４４の軸心位置は、可動取付板４１の平面に沿った１本の軸線上に一致するように形成され、且つこの軸心位置つまり蝶番の軸位置は、可動部材４０の正面寄りで左側面寄りの角部に位置するように形成される。また、可動取付板４１の縁部には、上記固定部材３１に対し可動部材４０を閉じる方向に回動させたとき、上記固定部材側の当接壁部３５に当接して停止するように、縁部を正面側に曲げた板部として、閉鎖壁部４８が形成される。
【００３４】
また、この閉鎖壁部４８は、軸受部材４３を設けた上突出板部４２の位置より上方に突出して上突出閉鎖壁部４８ａを形成している。この上突出閉鎖壁部４８ａは蝶番の可動部材４０が前扉５１に固定され、前扉が閉鎖されたとき、前扉５１と筐体５０との間の上部の隙間を塞ぐように、固定部材３１の上部に設けた上突出当接壁部３５ａに、この上突出閉鎖壁部４８ａは当接する。
【００３５】
さらに、軸受孔４４の切欠き開口部を閉じるために、回動部材４５が回動軸４５ａを軸にして回動可能に軸支される。回動部材４５は、軸受孔４４の切欠き部を閉鎖する部分を有するとともに、当該部分に続いて上ピン３３を案内するためのピン案内部４５ｃを凹状に設けて形成される。
【００３６】
さらに、手動操作により容易に回動できるように、回動部材４５の端部にはレバー操作部４５ｄが設けられている。また、回動部材４５にはばね部材４５ｂが装着され、ばね部材４５ｂは回動部材４５を図１９の時計方向に付勢している。回動部材４５のピン案内部４５ｃは、上ピン３３の移動力を受けて、回動部材４５が図１９の反時計方向に回動し、軸受孔４４の切欠き部を開放するように形成される。
【００３７】
また、図１９に示すように、固定部材３１側の上ピンを可動部材４０側の軸受孔４４に挿入する場合、上突出板部４２の背面側から上ピンを進入させ、回動部材４５のピン案内部４５ｃを押して、前方の軸受部材４３内に移動するように、上突出板部４２上に上ピンの導入路が形成されている。
【００３８】
このように構成された蝶番の固定部材３１は、その固定取付板３４に設けた取付孔と固定ねじを使用して、図２１〜図２５に示すように、ゲーム機の筐体５０の内側の左側面に、その上突出支持部３２と下突出支持部３６を前方に出して固定される。
【００３９】
一方、蝶番の可動部材４０は、ゲーム機の前扉５１の内側の左側面に、その可動取付板４１とそこに穿設した取付孔及び固定ねじを用いて、その上突出板部４２と下突出板部４６を前扉５１の内側に入れた状態で、縦に固定される。
【００４０】
前扉５１を筐体５０に対し開閉可能に装着する場合、先ず、前扉５１を持ち筐体５０に対し約４５度開いた状態で、可動部材４０の下突出板部４６の下軸受孔４７を、筐体５０側の固定部材３１の下突出支持部３６の下ピン３７に嵌め込む。下軸受孔４７は鋼板に穿設した孔であり、ピンと孔の嵌め合いには多少の間隙があるため、前扉５１は多少傾動可能である。
【００４１】
次に、その下突出支持部３６の下ピン３７を支点にして前扉５１を少し傾けながら、可動部材４０の上突出板部４２の軸受部材４３を、その固定部材３１の上突出支持部３２の上ピン３３の近傍に近づけ、その上ピン３３を、上突出板部４２上の進入路に進入させ、回動部材４５のピン案内部４５ｃを上ピン３３で押すように動かす。これにより、上ピン３３は、回動部材４５をばね部材４５ｂの付勢力に抗して回動させて、軸受孔４４を開くと共に、回動部材４５の回動によって開口した軸受孔４４内に滑るように進入する。そして、上ピン３３が軸受孔４４内に嵌入した後、回動部材４５がばね部材４５ｂの付勢力で元の位置に戻り、軸受孔４４の切欠き開口部が閉鎖され、上ピン３３は軸受部材４３の軸受孔４４に嵌合し、可動部材４０は固定部材３１に対し回動可能に正常位置に支持される状態となる。
【００４２】
このように、先ず、可動部材４０の下軸受孔４７を固定部材３１側の下ピン３７に嵌め、次に下ピン３７を支点にして前扉５１を少し水平方向に傾けながら、上突出板部４２上の軸受部材４３を、固定部材３１の上ピン３３に近づけ、上ピン３３によって回動部材４５を回動させながら、軸受部材４３の軸受孔４４に上ピン３３を滑り込ませるように嵌合させるため、従来のように、上部蝶番と下部蝶番のピンと軸受部の嵌合を、前枠を持ちながら同時に行なう必要がなく、重量のある前扉５１を非常に簡単に、筐体５０に対し蝶番を介して取り付けることができる。
【００４３】
蝶番を介して開閉可能に取り付けられた前扉２１は、図２３、図２５に示すように、その閉鎖位置では、固定部材３１の当接壁部３５に可動部材４０の閉鎖壁部４８が当接して所定の閉鎖位置を確保し、その当接によって筐体５０と前扉５１間の隙間が塞がれる。
【００４４】
このとき、当接壁部３５の前縁部は筐体５０の左側壁部の外側面と同一面上に位置し、前扉の閉鎖時、可動部材４０側の閉鎖壁部４８がこの位置の当接壁部３５の前縁部に当接する。このため、筐体５０と前扉５１との間の蝶番側に生じる隙間は、最も外側の面で固定部材３１の当接壁部３５と可動部材４０の閉鎖壁部４８との当接によって、確実に閉鎖することができる。
【００４５】
さらに、前扉５１の閉鎖時には、可動部材４０側の上突出閉鎖壁部４８ａが固定部材３１側の上突出当接壁部３５ａに当接するため、筐体５０と前扉５１の間の蝶番の上部に生じやすい隙間も、この上突出当接壁部３５ａと上突出閉鎖壁部４８ａとの当接により閉鎖することができる。
【００４６】
一方、前扉５１を最も広く開放側に回動したときには、図２２、図２４のように、可動部材４０の上突出板部４２の閉鎖壁部４８の一部が、固定部材３１の上突出支持部３２の側部に当接して回動端となり、これが最大開放角度となる。
【００４７】
前扉５１を筐体５０から外す場合、つまり蝶番の可動部材４０を固定部材３１より外す場合、前扉５１を筐体５０の前方に開いた状態で、可動部材４０の上突出板部４２上の回動部材４５を図１９の反時計方向に回動させれば、上ピン３３が軸受部材４３の軸受孔４４から容易に外れ、簡単に前扉５１つまり蝶番の可動部材４０を外すことができる。回動部材４５を回して軸受孔４４を開放しない状態では、可動部材４０の上突出板部４２が固定部材３１の上突出支持部３２の下面に当り、前扉５１を持ち上げることができないから、前扉５１を外すことはできない。
【００４８】
なお、上記実施例では、固定部材１、３１を一体に形成していたが、固定部材の上突出支持部と下突出支持部とは別個に形成することもできる。この場合、上突出支持部と下突出支持部とを繋ぐ固定取付板の部分が省略できるから、固定部材の軽量化が可能となる。

Then, after the upper pin 33 is fitted into the bearing hole 44, the rotating member 45 is returned to its original position by the biasing force of the spring member 45b, the notch opening of the bearing hole 44 is closed, and the upper pin 33 is The movable member 40 is engaged with the bearing hole 44 of the member 43 and is supported at a normal position so as to be rotatable with respect to the fixed member 31.
[0042]
In this way, first, the lower bearing hole 47 of the movable member 40 is fitted to the lower pin 37 on the fixed member 31 side, and then the upper protruding plate portion is tilted slightly in the horizontal direction with the lower pin 37 as a fulcrum. The bearing member 43 on 42 is brought close to the upper pin 33 of the fixing member 31, and the upper pin 33 is fitted into the bearing hole 44 of the bearing member 43 so that the upper pin 33 is slid while the rotating member 45 is rotated by the upper pin 33. Therefore, unlike the conventional case, it is not necessary to simultaneously fit the upper hinge pin and the lower hinge pin and the bearing portion while holding the front frame, and the heavy front door 51 can be very easily attached to the housing 50. Can be attached via a hinge.
[0043]
As shown in FIGS. 23 and 25, the front door 21 that is attached to be able to be opened and closed via a hinge has a closed wall portion 48 of the movable member 40 against the abutting wall portion 35 of the fixed member 31 in the closed position. A predetermined closed position is secured by contact, and the contact between the casing 50 and the front door 51 closes the gap.
[0044]
At this time, the front edge portion of the abutting wall portion 35 is located on the same plane as the outer side surface of the left side wall portion of the housing 50, and when the front door is closed, the closing wall portion 48 on the movable member 40 side is at this position. It contacts the front edge of the contact wall 35. For this reason, the gap generated on the hinge side between the housing 50 and the front door 51 is caused by the contact between the contact wall 35 of the fixed member 31 and the closed wall 48 of the movable member 40 on the outermost surface. It can be securely closed.
[0045]
Further, when the front door 51 is closed, the upper projecting closing wall portion 48a on the movable member 40 side contacts the upper projecting contact wall portion 35a on the fixed member 31 side. The gap that is likely to occur at the upper portion can also be closed by the contact between the upper protruding contact wall portion 35a and the upper protruding closing wall portion 48a.
[0046]
On the other hand, when the front door 51 is rotated to the widest open side, a part of the closing wall portion 48 of the upper protruding plate portion 42 of the movable member 40 protrudes upward of the fixed member 31 as shown in FIGS. It contacts with the side part of the support part 32 and becomes a rotation end, and this becomes a maximum opening angle.
[0047]
When the front door 51 is removed from the housing 50, that is, when the hinge movable member 40 is removed from the fixed member 31, the front door 51 is opened in front of the housing 50, and the movable member 40 is placed on the upper protruding plate portion 42. 19 is rotated counterclockwise in FIG. 19, the upper pin 33 can be easily removed from the bearing hole 44 of the bearing member 43, and the front door 51, that is, the hinge movable member 40 can be easily removed. it can. In a state where the rotating member 45 is not rotated to open the bearing hole 44, the upper projecting plate portion 42 of the movable member 40 hits the lower surface of the upper projecting support portion 32 of the fixed member 31 and the front door 51 cannot be lifted. The front door 51 cannot be removed.
[0048]
In addition, in the said Example, although the fixing members 1 and 31 were formed integrally, the upper protrusion support part and lower protrusion support part of a fixing member can also be formed separately. In this case, since the portion of the fixed mounting plate that connects the upper projecting support portion and the lower projecting support portion can be omitted, the weight of the fixing member can be reduced.
[0049]
【The invention's effect】
  As described above, according to the hinge for a game machine of the present invention, the lower bearing hole of the movable member is fitted to the lower pin on the fixed member side, and then the front door is tilted slightly in the horizontal direction with the lower pin as a fulcrum. Fit the bearing member on the upper protruding plate part close to the upper pin of the fixed member, open the bearing hole of the bearing member while rotating the rotating member with the upper pin, and slide the upper pin there Therefore, unlike the conventional case, it is not necessary to simultaneously fit the pin of the upper hinge and the lower hinge and the bearing part while holding the front frame, and the heavy front door can be hinged to the housing very easily. Can be attached via.Further, the upper pin of the upper projecting support part and the corresponding lower pin, that is, the hinge shaft pin, can be positioned on the left front side from the mounting surface of the fixing member. Even when a hinge is attached to the inside of the body and the front door and a thick front door is used, it is not necessary to cut out the hinge mounting part on the front side of the housing in a concave shape. The gap can be minimized.
[0050]
According to a second aspect of the present invention, a pin guide portion that guides the upper pin is provided on the rotating member, a spring member that biases the rotating member is provided on the side of the bearing member that closes the bearing hole, and the upper pin is inserted into the bearing hole. If the rotating member is rotated by the upper pin and inserted into the bearing hole of the bearing member when inserted into the shaft, the rotating member automatically rotates at the time of attachment / detachment by the movement of the upper pin and the spring member. Thus, the movable member can be attached and detached more easily.
