Description

【０００１】
【産業上の利用分野】
本発明は、パチンコ機の遊技板の前面を被うガラスを安定的にガラス枠に装着するようにしたガラス枠に関する。
【０００２】
【従来の技術】
一般にパチンコ機の遊技板の前面を被うガラスはガラス枠に嵌め入れて前枠か、若しくはこの前枠に蝶着される飾り枠に取付られるが、従来のガラス枠はスチール製の帯板をプレス成形によって２条のガラス装着溝をもった枠材に形成し、この枠材を装着溝を内側にして矩形に折り曲げ枠本体を形成している。そして、通常はこの枠本体の前縁部に沿って額縁形をなす同一素材の飾り前面枠を組付けて構成し、上に向け開放される上記装着溝の端部からそれぞれ落とし込むようにして２枚のガラス板を間隔を置いて対面する如く装着している。
【０００３】
このガラス枠は通常の場合前枠の前面の一側縁に蝶着し、或いは前枠に蝶着される飾り枠に対して開閉自由に取付けられ、前枠の開口部を閉塞して遊技板の前面を被うようにしているが、このガラス枠は単に遊技板の前面を被うだけでなく、ガラス枠と前枠乃至飾り枠との空隙を突いて行われる不正行為を防止するため常に密閉状態に閉塞されなければならず、またこのため装着されるガラスはガラス枠と一体となってこの間に空隙が生じないようにすると共に、ガタ付かないようにしなければならない。
【０００４】
【発明が解決しようとする問題点】
しかし、スチール製のガラス枠は上述したようにプレス成形によるためスプリングバックによって形状が戻り精度が出し難く、ことにガラスの装着溝の幅に不安定さがあり装着したガラスとの間に不要な間隙を生じる問題がありガタ付きを生じ、また防犯効果上好ましくなかった。また従来のガラス枠は枠本体と飾り前面枠とを別体に成形してその後この両者を接合させ組み立てる構造に係るため製造性が悪く、しかも強度的にも不安定なものがあり防犯上問題があった。
【０００５】
本発明は、この様な問題点に鑑みこれを改善する目的でなされたもので、ガラス枠の本体を形成する枠材をアルミの押出形材にしてこれに設けるガラスの装着溝を正確に形成して精度をもったガラス枠を形成すると共に、上記ガラスの装着溝とこれに装着されるガラスとの間の空隙を効果的に詰めてガタ止めしたパチンコ機のガラス枠を提供せんとするものである。
【０００６】
【問題点を解決するための手段】
本発明は上述の目的に基づきなされたもので、その特徴とするところは突条を挟んで２条のガラス装着溝を並行に備える断面Ｅ字形に押出成形されるアルミ型材を素材にして該型材を前記装着溝を内側にコ字形に屈曲し、一側枠部の両端から並行する２側枠部を延設すると共に、上記並行する２側枠部の端部の間に他側枠部を渡して矩形の枠本体を組み立て、その一方、前記２側枠部の端部において開放する前記装着溝の端部からそれぞれガラスの縁部を嵌入して２枚のガラスを間隔を置いて対面状に装着してなるパチンコ機のガラス枠において、前記２条の装着溝には弧状に屈曲するバネ片を有するガタ止め部材を嵌合し、上記バネ片を溝側壁と前記装着されるガラスとの間に弾力的に介挿してなることを特徴としたガラス枠を提供することにある。
【０００７】
また本発明は、前記ガタ止め部材は突条に嵌合する断面コ字型をなす取付部を有し、該取付部の一方若しくは双方の端部からバネ片を延設して前記突条に対して取付部を嵌合止着するのに伴わせて上記バネ片を突条側の溝側壁とガラスとの間に介挿してなることを特徴としたガラス枠を提供することにある。
【０００８】
また本発明は、前記ガタ止め部材の取付部には下面に小突起を垂下し、他方ガラス枠の突条上面には嵌入小孔を形成して該小孔に前記小突起を圧入することによってガタ止め部材を止着してなることを特徴としたガラス枠を提供することにある。
【０００９】
【作用】
本発明によれば、上述の構成によって明らかなようにガラス枠本体を形成する枠材を突条を挟んで並行する２条のガラス装着溝を有する断面Ｅ字形をなすアルミの押出型材としたことから容易に精度の高い枠体を得ることができ、従ってガラスの板厚に対応させた枠本体を容易に成形することができると共に、上記装着溝とこれに装着されるガラスとの間にガタ止めが介挿されることから安定したガラス枠が得られる。
次に、本発明の特徴とするところを図面に示す実施例に従って詳細に説明することにする。
【００１０】
【実施例】
図１は本発明に係るガラス枠を装着したパチンコ機のガラスを取り外した状態の斜視図で、図２は機枠から外した前枠の正面図、図３は前枠に組付ける諸種の部材を外した状態を示す分解斜視図である。図面において１ａはパチンコ機の機枠であり、１ｂは前枠である。
前枠１ｂは上下の枠部分２，３と左右の枠部分４，５によって縦長矩形の額縁形に形成してあり、各枠部分を平板にして全体を扁平に形成してある。この前枠は合成樹脂を素材に一体成形してあり、左枠部分４側の上端と下端には前記機枠１ａに対して開閉自由に蝶着するための上下の蝶着片６，７を止め付ける金属製の当板８，９を取付けてあり、また開口部１０に臨む右枠部分５の内側縁には後述する飾り枠を施錠する錠装置１１を止め付ける金属製当板１２，１３が取付けてある。
【００１１】
この前枠１ｂは前記機枠の前面を被う大きさに形成してあり、下枠部分３の前面は後述する下皿基板１４を止着する取付部として平滑な面に形成してある。そして、中央部には賞球の出口となる窓１５を開設し、左右及び中央部の適所には下皿基板１４の背面から突出する鉤形の係止爪を掛け止める係止孔１６が設けてある。
【００１２】
上記開口部１０は後述する遊技板の前面を覗かせると共に打球発射装置の前面を覗かせるものであり、この開口部には飾り枠１７と上皿基板１８が組付けられる。
一方、前記左枠部分４には上下の端部に設けられる蝶着片６，７の中間に位置するように中間の蝶着片１９が設けてある。この蝶着片１９と上蝶着片６とにより飾り枠１７の左側縁の上下両縁を枢着し、これを開閉自由に蝶着する。その一方上記中間蝶着片１９とこの蝶着片と向い合う下皿基板１４の上端部の間に上皿基板１８の左側縁部を収め、その上下両端を各枢着して同じく開閉自由に蝶着し、この両者を揃えて閉じることによって開口部１０を塞ぐことができるようにしてある。
【００１３】
上記飾り枠１７は図１０に示したように蝶着側一側縁の上端部にバネによって上方に突出するように付勢される枢着軸２０を備え、この枢着軸２０を上蝶着片６に設ける軸受孔に嵌合することによって、また下端部に下向きに突出する軸２１を中間蝶着片１９の軸受孔に嵌合させることによって蝶着するようにしてあり、他方、上皿基板１８は蝶着側下端部に設ける下向きの軸２２を下皿基板１４の一側縁上端部に設ける軸受孔２３に嵌合させ、上端部に設ける軸受孔２４に前記飾り枠１７の軸２１を嵌合させることによってそれぞれ蝶着するようにしてある。
【００１４】
上記上皿基板１８は軸２２を引き上げ軸受孔２３から抜き取ることによって蝶着を解除することができ、前枠１ｂから取り外すことができるものとなっている（これについては後記詳述する。）。また飾り枠１７はバネに抗して軸２０を引き下げ上蝶着片６から外したのち、飾り枠１７を持ち上げて軸２１を中間蝶着片１９から外すことによって前枠１から取り外せるものとなっている。勿論、飾り枠１７、上皿基板１８の両者は上述した取り外しの逆の作業によって前枠１ｂに組付けることができる。
【００１５】
飾り枠１７は合成樹脂を材料に額縁形に形成してあり、閉じたとき前枠１ｂの略上半部の全面を被い隠せる大きさに形成してある。ここに示す飾り枠は上縁部１７ａと左右の縁部１７ｂ，１７ｃを前方に膨出させて立体化し、背面に中空部２５を形成して照明乃至表示用ランプのリード線の配線空間を設けている。上記各縁部の前面には着色した半透明のレンズカバー２６，２７，２８を装着して各縁部に形成する透孔２９を通して前方に向け臨む上記照明乃至表示用ランプを被うようにしてある。
【００１６】
上記レンズカバー２６，２７，２８はそれぞれの縁部１７ａ，１７ｂ，１７ｃの前面に形成する縁取りした装着部３０に嵌め付けるようにして取付けるようにしてあり、それぞれのカバーの縁から後方に向け突出する爪３１を上記装着部３０の縁に沿って設ける切欠き係止部３２に弾性を利用して係入し取付けられる。尚、ここでは左右のカバー２７，２８を装着したのち上部のカバー２６を装着して三者の端部を継ぎ合せて飾り枠１７の前面に門形に形成し飾るようにしてある。
【００１７】
図中、３３は上記飾り枠１７の背面から開口部３４を塞ぐ本発明に係るガラス枠である。このガラス枠３３は２枚のガラス３５，３５を間隔をおいて対面状に装着するもので、一側縁を飾り枠の左縁部１７ｂの背面に蝶着して開閉自由に取付けてある。
【００１８】
ここに示したガラス枠３３は防犯効果を高めると共に装着時のガタ付きを防止するためアルミの押出型材を素材に形成して精度を高めてある。ここに使用される型材は図１６に示したように中央部に中心部分に沿って円形の貫通穴を設ける突条３６を長さ方向に沿って隆設し、この突条３６を挟んで２条のガラス装着溝３７，３７を設けてあり、実質的に断面Ｅ字型をなすように形成してある。この型材を長さの途中において図示するようにコ字形に屈曲させて一側枠たる左縦枠３３ａとその上下の端から他の側枠たる横枠３３ｂ，３３ｃを並行をなすように延設し、更にこの両横枠３３ｂ，３３ｃの自由端間に別の断面コ字型をなすアルミの型材からなる他の側枠たる右縦枠３３ｄを渡して全体として矩形の枠に組み立て構成してある。
【００１９】
上記右縦枠３３ｄは図１４，１５に示すようにコ字形に屈曲する型材の突条３６の幅員に合わせた細身の型材であり、上下の横枠３３ｂ，３３ｃの端部に臨む突条３６，３６間に両端を渡してビス（図示せず）を前記円形の貫通穴に揉み込むことによって連結し矩形に組立ててあり、またこの右縦枠３３ｄの連結によって上下の横枠のガラス装着溝３７，３７の端部を開放し（図１５参照）、ここからガラス３５の挿入が行えるようにしてある。
【００２０】
ところで、ガラス枠３３を構成する型材は前述した様に一側枠たる左縦枠３３ａを中心にしてその両端を直角に折り曲げることによって上下の側枠たる横枠３３ｂ，３３ｃを形成するものとしているが、この折曲げによって形成されるコーナー部３８，３８は直角とはならず弧状を呈することになる。このため矩形に切り出すガラス３５を前記装着溝３７の端部から差し入れ装着すると、直角をなすガラスの隅部が弧状をなす上記コーナー部３８に収まらず、その結果左縦枠３３ａとガラス３５の側縁との間に隙間が出来ることになる。
【００２１】
上記の問題はガラス３５の隅部をコーナー部３８に合わせて弧状に隅取りすれば解決されるが、ガラスにこの様な前加工を施すことはコスト高になると同時に、ガラスの一側縁上下両隅部にのみ加工することになることからガラス３５の嵌め込みに方向性が生じ、取扱い上不便になる。
そこで本発明では両コーナー部３８，３８に当たるガラス装着溝３７，３７の底部を弧状をなす部分において長さ方向に添って切除し、長孔状の突出し穴３９、３９を開設してガラスの隅部が抜き出るようにし、矩形に形成されるガラス３５の隅部がガラス枠の弧状のコーナー部３８に対してぴったり正確に収まるようにしてある。
【００２２】
図中の符号、４０はガラス枠内に嵌め入れたガラス３５のガタ付きを止めるため上下の横枠３３ｂ，３３ｃに取付けたガタ止め部材である。このガタ止め部材４０は弾性を有した合成樹脂を素材に成形してあり、図示するように断面コ字形をなす取付部４０ａとこの取付部４０ａの両端部から延設する二股の弧状をなすバネ片４０ｂからなっており、取付部４０ａを各横枠の突条３６に被せるように嵌め付け、これの下面から垂設する小突起４０ｃを突条３６の上面に設ける嵌入小孔４１に圧入することで取付き、この取付によって各バネ片４０ｂをそれぞれの装着溝３７内に長さ方向に沿って挿入するようにしてある。
【００２３】
図１９及び図２０は上記ガタ止め部材４０の装着と、このガタ止め部材によるガラス３５のガタ付き防止の実際を下横枠３３ｃにおいて示したものである。ガラス装着溝３７の端部から挿入されるガラス３５は横枠の途中に取付けられるガタ止め部材４０に達したところで、溝３７に横たわるバネ片４０ｂを押し潰して侵入し、左縦枠３３ａの装着溝３７に一側縁を嵌め入れるまでスライドさせて装着される。
【００２４】
２枚のガラス３５は同様にしてそれぞれの装着溝３７に差し入れられ、それぞれのガタ止め部材４０のバネ片４０ｂを押し潰し、その反発力で溝の側壁に押圧されることによってガタ止めされることになり、且つガラス間の間隔を保つことになる。このガタ止め部材４０は上横枠３３ｂにも相対向するように装着され、上下において弾力的にガタ止めすることになる。
【００２５】
ところで、このガタ止め部材４０の装着のため、この実施例ではガラス枠の各装着溝３７の幅をガラス３５の板厚より広幅に形成してあり、ガラス３５と共に弧状のバネ片４０ｂが容易に収まるようにしてある。またこの幅を拡張したことによってガラス３５の嵌め付けが楽に行えるようにしてある。また同時にガラス３５を内外方向から押圧した場合、その力をバネ片４０ｂが吸収してくれるようにしてある。
特に上記バネ片４０ｂによる押圧の吸収はこのガラス枠３３を前記飾り枠１７に閉じ合わせたとき、開口部３４の後方に向って突き出す縁３４ａを前方のガラス３５の前面に当接させ密着させることを保障するものであり、更にはこの閉じあわせに当たって飾り枠１７の縁３４ａとガラス枠３３に収まるガラス３５の双方の位置関係に誤差がある場合、この誤差を吸収することができ有効に作用することになる。
【００２６】
尚、上記ガタ止め部材４０は当該実施例において取付部４０ａの両端にバネ片４０ｂを一対宛備えた例につき説明しているが、一端側のバネ片４０ｂのみであっても、また両端から派生する２つのバネ片の一方を省略して並行する２条の装着溝３７に対して１つづつのバネ片が挿入されるようにしても実施できることは言うまでもない。
また、このガタ止め部材４０は前述したようにガラス枠に嵌め込まれるガラス３５の板厚と装着溝３７の溝巾の差から生ずるガタ付きを防止するための外、ガラス枠を飾り枠１７に閉じ合わせたとき両者間の閉じ合わせの誤差から生ずるガタ付きを防止するためにもあることから、その取付位置、個数或いはバネ片の数等の選択は実施に当たって適宜選択されることになる。
【００２７】
図中、符号４２，４３はガラス枠３３を飾り枠１７に蝶着するための枢着片である。この枢着片は帯状の金属片をクランク状に屈曲させ形成したもので、ガラス枠３３のコーナー部３８の外側に添わせてリベット等を使って一体に止め付けられる。この枢着片の取付けによりコーナー部３８の突出し穴３９から外に突出するガラス３５の隅部が被われることになり取扱い時の危険が回避されることになる（図１７参照）。
【００２８】
上記ガラス枠３３は飾り枠１７の左縁部１７ｂの背面の上下に備えられる枢着軸４４，４５に上記枢着片４２，４３の軸受片４２ａ，４３ａを各枢着させることによって開閉自由に取付き、また自由端側の右縦枠３３ｄに設けるピン４６を係止爪４７に係合させることによって閉塞状態に保持される。
【００２９】
係止爪４７は右縁部１７ｃの背面に立設する取付台４８にビス４９で止め付け立ち上げてあり、ガラス枠３３の閉塞によって上方（実際には後方水平方向）から近付いてくるピン４６を爪５０の頭部に受けてその傾斜面に透導して一旦撓ませたのち掛け止めるられるようにしてある。
図中、５１はこのガラス枠の閉塞に際してピン４６を係止爪４７に真直に衝合させ係合するよう誘導するためのガイドであり、飾り枠の右縁部１７ｃの背面部から壁状に立設し、縦に切込むスリット５２にピン４６を滑合させ係止爪４７に誘導できるようにしてある。尚、図中、５３は上記係止爪４７を位置決め固定する突起である。
【００３０】
ガラス枠３３を背面に備えた飾り枠１７は前述したように枢着軸２０，２１を支点に前枠１ｂの前面に接面するように閉じ合され、自由端側となる右縁部１７ｃの背面に備える係止爪（図示せず）を施錠装置１１に掛け止め施錠される。そして、このとき前枠１の右枠部５の前面中央部に備える鍵穴飾り５４を右縁部１７ｃに設ける切欠き部５５に受け入れ両者の衝突を避けるようにしてある。
【００３１】
鍵穴飾り５４は前枠１ｂを機枠１ａに施錠して任意に開放しないようにするシリンダ錠５６を前枠１ｂに取付けるための取付部材である。この鍵穴飾りは前方からシリンダ錠の鍵穴に鍵を差し入れ開錠したとき、この鍵を差し入れたまゝ飾り枠１７を自由に開閉操作できるよう鍵の操作摘みの幅より広幅に形成してあり、また切欠き部５５はこの鍵穴飾り５４を受け入れると同時に両者の間に不要の間隙が生じない大きさに形成してある。
【００３２】
上記鍵穴飾り５４は飾り枠１７を閉じ合せたとき一体感を出すため前面にはカバー２８に調子を揃えたレンズカバー５７が装着してある。図中５８はシリンダ錠５６の回転片であり、機枠１ａに掛け止められる係止フック５９を解錠操作時に作動させることになる。
【００３３】
一方、前記上皿基板１８は前述したように軸２２を下皿基板１４の軸受孔２３に軸着し、左側上端部の軸受孔２４に中間蝶着片１９に枢着した軸２１を嵌入させることによって蝶着され開閉自由に前枠１ｂに組付けられるが、この基板は前記飾り枠１７に合せて合成樹脂を素材に成形し、上部前面の中央部に賞球装置から放出される賞球を受ける受皿６０を一体に設け、基板背面の適所には打球供給樋６１や、放出賞球を賞球樋から受け取る連絡樋６２を装備する裏基板（図示せず）を止め付けるためのビス受け６３が設けてある。そして、蝶着端側の背面には軸２２を支持し、また軸受孔２４を補強する金属製補強材６４が、そして自由端側の背面には係止部材６５がそれぞれ取付けてある。
【００３４】
補強材６４は帯状の金属板の両端を直角に折り曲げ、一方を軸受孔２４の補強片６６とし、他方を軸２２の支持片６７とするもので、上記補強片６６には軸受孔２４に対応した位置に透孔６８を設け、支持片６７には軸２２を受け入れる挿通孔を設けてある。
軸２２は金属丸棒をＬ字形に折り曲げ形成したもので、一方の軸を摘みとして補強材に縦に開設するスリット６９に滑合させて上記支持片６７の挿通孔に通した他方の軸をこの摘みにより上下に操作できるようにしてある。
【００３５】
この軸２２の上下の移動は上皿基板１８の装着に便ならしめるためのもので、前述したように中間蝶着片１９に通した軸２１を軸受孔２４、透孔６８に挿通したのち、軸２２を引き上げて下皿基板１４の軸受孔２３の直上に臨ませ、その後スリット６９に滑合する軸部（摘み）を操作して引き下げ軸受孔２３に突入させることによって上皿基板１８の組付けが行えるようにしてある。
【００３６】
一方、係止部材６５は取付片７０とスライド係止片７１からなっており、取付片７０を介して基板の自由端側背面に設けられる取付部７２に装着される。
スライド係止片７１はこの片に設ける爪７３と取付片７０に設ける爪７４との間に縮設するバネ（図示せず）によって常時上方に付勢され、前記軸２１，２２を支点に上皿基板１８を回動し閉塞したとき、このスライド係止片７１から後方に向けて突設する係止爪７５を前枠１の右枠部５に設ける係止部７６に上記バネに抗して掛け止められるようにしてある。
【００３７】
上記係止部７６は金属板を打抜き形成したものであり、係止爪７５はこの係止部７６に開設する穴７７に突入し掛け止められることになる。そして、係止部材６５は上皿基板の自由端側上端に頭を出すスライド係止片７１の上端７８を押圧することによって係止爪７５の係合を解き上皿基板の開放を許すことになる。
【００３８】
上皿基板１８の前面に設けられる受皿６０の前面には飾り枠１７の左縁部１７ｂの前面に沿って縦長に配置されるレンズカバー２７に揃えてこれに連続するように横長の飾りレンズカバー７９が配設される。また、前面右側縁には同じくレンズカバー２８の下端に接続するように飾りレンズカバー８０を配設し、この上皿基板１８と飾り枠１７とが一つの統一した意匠の中にあるように揃えてある。
【００３９】
下皿基板１４は前枠１ｂの下枠部３の前面に固定されるが、上皿基板と同様に合成樹脂を材料に成形されるもので、前面には受皿８１と灰皿８２の取付部８３と打球発射用の操作グリップ８４を装置する装着部８５が一体に備えられ、上記受皿８１の前面にはレンズカバー８０に続く飾りのレンズカバー８６を装着して上皿基板と一体となる意匠が施してある。
【００４０】
図中、８７は前枠１ｂの背面に取付けられる機構枠体である。この機構枠体８７は金属板で浅い箱形に形成してあり、内部下方には上下に仕切るように遊技板８８の受台８９が設けてあり、その前面部には打球発射装置９０ａと発射レール９０ｂが備えられる。この機構枠体の背面上部には賞球タンク９１が取付けられ、窓９２を開設した背板９３の背面には賞球装置、賞球放出樋、セーフ球集合室、セーフ球通路等の機構装置、部品類が設備され、更にこれら部品類を被うカバー９４が取付けられると共に、機構枠体の下方には賞球箱９５が取付けられ、前記下皿基板１４の背後から受皿８１に賞球を送り出せるようにしてある。
【００４１】
遊技板８８は前枠１ｂの開口部１０を塞ぐ飾り枠１７、上皿基板１８を開放して前方から機構枠体内部に持込み、機構枠体に備える止めクリップ（図示せず）で遊技板の周縁部を固定し着脱自由に取付けられ、常には閉塞される飾り枠１７の開口部３４に装着されるガラス枠３３を通して前方から覗けるようにしてある。
【００４２】
ところで、前記飾り枠１７及び上皿基板１８は使用時塞閉状態におかれ、前枠１ｂの開口部１０を閉ざすことになるが、両者の召し合せ部分を通して行われる遊技板に対する不正行為を防止するため、前枠１ｂの前面外周縁には縁に沿って段部９６を設け、また飾り枠１７と上皿基板１８の周縁部には上記段部９６に嵌り付く後向きの縁部９７，９８が設けてある。
【００４３】
飾り枠１７と上皿基板１８の横幅を前枠１ｂの横幅に揃えてその前面を被う大きさに形成してあるのは一つの理由として両者の召し合わせ部分を前枠１ｂの開口部１０から離して不正行為を防止することにあるが、更にここでは段部９６と縁部９７，９８の噛み合せを加えることによってその効果を高めるものにしてある。
【００４４】
本発明における不正行為の防止策について更に説明すると、前枠の右枠部５の前面に取付けられる鍵穴飾り５４とこれに臨む飾り枠１７の右縁部１７ｃに設けられる切欠き部５５との間にも同じく噛み合せ関係が形成してある。即ち、図８に示す如く鍵穴飾り５４には内側の縁９９を断面コ字形に形成して前方に開放する溝形に形成し、この縁に切欠き部５５の後向きの縁１００を嵌め入れて両者の召し合せ部分からのピアノ線等の不正部材の侵入が阻止できるようにしてあるのである。
【００４５】
また、飾り枠１７と上皿基板１８とが向い合う縁部には図５及び図７に示したように上皿基板の上縁１０１を断面コ字形にして前方に開放する溝を設け、他方飾り枠１７の下縁部１７ｄは後向きの縁１０２にして両者を閉じ合せたとき噛み合って前後方向に真直な空隙が出来ないようにしてある。
【００４６】
本発明を図面に従って説明したが、前述した各部は組立製造する前に、各独立のものとして構成され、機枠については矩形の枠体として、また前枠１ｂは扁平な額縁形に、飾り枠１７、上皿基板１８及び下皿基板１４はそれぞれ合成樹脂を素材に個別に形成し、機構枠体８７については金属板により別体に形成することになる。
【００４７】
この個別に形成される各部につき、機枠１ａについては前枠１ｂを蝶着する蝶着片１０３を予め取付け、前枠１ｂには同じく機枠１ａの蝶着片に対応させて上下の蝶着片６，７と中間蝶着片１９及び施錠装置１１を予め取付けてそれぞれ基本構成体として準備しておかれる。
【００４８】
その一方、飾り枠１７は前面を飾るレンズカバー２６，２７，２８を装着しておくと共に表示若しくは照明のランプを装着し、上皿基板及び下皿基板についても同様にレンズカバー７９，８６を装着しておくことになる。
機構枠体８７は貯留タンク９１を始めとして諸種の機構部品類を装着し、前面には発射装置９０ａ、発射レール９０ｂ等を組付けておくことになる。
【００４９】
この様に各部材を個別に、しかもそれぞれ予め定められた部品類を装着した部材は独立した状態で保管、管理され、製造の最終組立の段階で集められ、前述した組合せ関係において結合組立て完成される。この組立時には相互の組立調整と電気関係並びに入賞に伴う賞球の放出等の諸調整、検査が行われる。
【００５０】
尚、飾り枠１７、上皿基板１８、下皿基板１４は組立完成時にパチンコ機の前面に現れ、パチンコ機のデザインを決定することから前枠１ｂとの組立に先立って三者の取り合せが決定され、この段階でパチンコ機そのもののデザインが確定することになる。このことから前枠１ｂと機構枠体８７を同一にして飾り枠１７、上皿下皿の基板１４，１８の取り合わせを変えることによってデザインを違えた複数種のパチンコ機を製造することができることになる。勿論、パチンコ機は遊技板８８の選択によって、またこの遊技板に組込まれる入賞装置に関連するゲームソフトの変更によって機種が変化し、異なるパチンコ機として組立られることは言うまでもない。
【００５１】
【発明の効果】
以上本発明を図示する実施例につき説明したが、本発明によればガラス枠本体をアルミの押出型材によって構成したことからガラスの装着溝をガラスの板厚に合わせた適正な幅に成形することができ、従って精度の高いガラス枠を提供出来ると共に、上記装着溝には弾性を有したガタ止め部材が介挿されガラスと装着溝の側壁との空隙を埋めることからガタ付きのない、しかも安全なガラス枠を提供することができる。
また本発明は上記ガタ止め部材によってガラスが前方に押圧された状態にあることからガラス枠を閉じてガラスを飾り枠に添わせたとき密着し、またこの両者間に多少の位置的誤差があってもこれを上記ガタ止め部材が吸収してくれることから安定した閉じ合わせがえられることになる。
また本発明のガタ止め部材は合成樹脂による成形品であるので容易に且つ廉価に提供できる利点がある。

Generally, the glass that covers the front of the game board of a pachinko machine is fitted into a glass frame and attached to a front frame or a decorative frame that is hinged to this front frame, but a conventional glass frame uses a steel band plate. A frame material having two glass mounting grooves is formed by press molding, and this frame material is bent into a rectangular shape with the mounting grooves inside to form a frame main body. A decorative front frame of the same material, which usually forms a picture frame, is assembled along the front edge of the frame body, and is dropped from an end of the mounting groove which is opened upward. The glass plates are mounted facing each other at intervals.
[0003]
This glass frame is usually hinged to one side edge of the front surface of the front frame, or is attached to a decorative frame hinged to the front frame so that it can be opened and closed freely. However, this glass frame not only covers the front of the game board, but also always prevents fraudulent acts performed by piercing the gap between the glass frame and the front frame or decorative frame. The glass must be closed in a closed state, and the glass to be mounted must be integrated with the glass frame so that no gap is formed between them and the glass is not rattled.
[0004]
[Problems to be solved by the invention]
However, since the steel glass frame is formed by press molding as described above, the shape is difficult to return due to the springback, and the width of the mounting groove of the glass is unstable. There is a problem that a gap is generated, which causes backlash, and is not preferable in terms of the security effect. In addition, the conventional glass frame has a structure in which the frame main body and the decorative front frame are formed separately and then the two are joined and assembled, so that the manufacturability is poor, and the strength is also unstable. was there.

The present invention has been made based on the above-mentioned object, and is characterized by using an aluminum mold material extruded into an E-shaped cross section having two glass mounting grooves in parallel with a ridge therebetween. The mounting groove is bent in a U-shape inward, two parallel side frame portions are extended from both ends of one side frame portion, and the other side frame portion is placed between the ends of the parallel two side frame portions. The rectangular frame body is assembled by handing over, while the edge of the glass is inserted from the end of the mounting groove opened at the end of the two side frame portion, and the two glasses are faced at an interval. In a glass frame of a pachinko machine mounted on a pachinko machine, a play preventing member having a spring piece bent in an arc is fitted into the two mounting grooves, and the spring piece is formed between the groove side wall and the glass to be mounted. To provide a glass frame characterized by being elastically interposed therebetween. Located in.
[0007]
Further, according to the present invention, the play preventing member has a mounting portion having a U-shaped cross section to be fitted to the ridge, and a spring piece is extended from one or both ends of the mounting portion to the ridge. Another object of the present invention is to provide a glass frame characterized in that the spring piece is inserted between the glass and the groove side wall on the ridge side as the mounting portion is fitted and fixed.
[0008]
Also, the present invention is characterized in that a small protrusion is hung on the lower surface of the mounting portion of the backlash preventing member, while a small fitting hole is formed on the upper surface of the ridge of the glass frame, and the small protrusion is pressed into the small hole. It is an object of the present invention to provide a glass frame characterized by fastening a play preventing member.
[0009]
[Operation]
According to the present invention, as is apparent from the above-described configuration, the frame material forming the glass frame body is an aluminum extruded die material having an E-shaped cross section having two glass mounting grooves parallel to each other with a ridge therebetween. From the mounting groove and the glass to be mounted on the frame can be easily formed, so that the frame body corresponding to the thickness of the glass can be easily formed. A stable glass frame is obtained because the stopper is inserted.
Next, features of the present invention will be described in detail with reference to embodiments shown in the drawings.

[0011]
The front frame 1b is formed to have a size covering the front surface of the machine frame, and the front surface of the lower frame portion 3 is formed as a smooth surface as a mounting portion for fixing a lower plate substrate 14 described later. A window 15 serving as an exit of a prize ball is opened in the center, and a locking hole 16 for hooking a hook-shaped locking claw protruding from the back surface of the lower plate substrate 14 is provided at an appropriate position on the left, right, and center. It is.
[0012]
The opening 10 allows the front face of the game board to be seen and the front face of the hitting and launching device to be seen, and the decorative frame 17 and the upper plate 18 are assembled to this opening.
On the other hand, an intermediate hinge piece 19 is provided on the left frame portion 4 so as to be located between the hinge pieces 6 and 7 provided at the upper and lower ends. The upper and lower edges of the left side edge of the decorative frame 17 are pivotally connected to the hinge piece 19 and the upper hinge piece 6, and the hinge is freely opened and closed. On the other hand, the left edge of the upper plate 18 is housed between the middle hinged piece 19 and the upper end of the lower plate 14 facing the hinged piece, and the upper and lower ends are pivotally attached to each other to open and close similarly. The opening 10 can be closed by hinged and closing both together.
[0013]
As shown in FIG. 10, the decorative frame 17 has a pivot shaft 20 urged by a spring so as to protrude upward at the upper end of one side edge on the hinge side. The hinge is formed by fitting into a bearing hole provided in the piece 6 and by fitting a shaft 21 projecting downward at a lower end portion into a bearing hole of the intermediate hinge piece 19, and The base plate 18 has a downward shaft 22 provided at the lower end on the hinged side fitted into a bearing hole 23 provided at the upper end of one side edge of the lower plate substrate 14, and the shaft 21 of the decorative frame 17 is fitted into a bearing hole 24 provided at the upper end. Are fitted to each other so as to be hinged.
[0014]
The upper plate 18 can be released from the hinge by pulling up the shaft 22 from the bearing hole 23 and can be removed from the front frame 1b (this will be described later in detail). The decorative frame 17 can be removed from the front frame 1 by pulling the shaft 20 down from the upper hinge piece 6 against the spring and then lifting the decorative frame 17 to remove the shaft 21 from the intermediate hinge piece 19. ing. Needless to say, both the decorative frame 17 and the upper plate 18 can be assembled to the front frame 1b by performing the above-described removal operation in reverse.
[0015]
The decorative frame 17 is made of a synthetic resin in the shape of a frame, and is formed in such a size that it can cover and cover almost the entire upper half of the front frame 1b when closed. In the decorative frame shown here, the upper edge 17a and the left and right edges 17b, 17c are bulged forward to be three-dimensional, and a hollow portion 25 is formed on the back surface to provide a wiring space for lead wires of lighting or display lamps. ing. A colored translucent lens cover 26, 27, 28 is mounted on the front surface of each edge to cover the illumination or display lamp facing forward through a through hole 29 formed in each edge. is there.
[0016]
The lens covers 26, 27, and 28 are mounted so as to be fitted to a mounting portion 30 formed on the front surface of each of the edge portions 17a, 17b, and 17c, and project rearward from the edge of each cover. The hook 31 is engaged and attached to the notch engaging portion 32 provided along the edge of the mounting portion 30 by using elasticity. In this case, the left and right covers 27 and 28 are attached, then the upper cover 26 is attached, and the ends of the three members are joined to form a gate shape on the front surface of the decorative frame 17 for decoration.
[0017]
In the figure, reference numeral 33 denotes a glass frame according to the present invention for closing the opening 34 from the back of the decorative frame 17. The glass frame 33 is provided with two glass plates 35, 35 facing each other at an interval, and has one side edge hinged to the back of the left edge portion 17b of the decorative frame, and is freely openable and closable.
[0018]
The glass frame 33 shown here is formed by extruding an aluminum material into the material to enhance the security effect and to prevent rattling at the time of mounting, thereby improving the accuracy. As shown in FIG. 16, the profile used here is provided with a ridge 36 provided with a circular through hole at the center along the center portion along the lengthwise direction. The glass mounting grooves 37, 37 are provided, and are formed so as to have a substantially E-shaped cross section. As shown in the figure, this profile is bent in a U-shape as shown in the figure, and a left vertical frame 33a as one side frame and horizontal frames 33b and 33c as other side frames are extended from the upper and lower ends thereof in parallel. Further, a right vertical frame 33d, which is another side frame made of aluminum having a U-shaped cross section, is passed between the free ends of the two horizontal frames 33b and 33c, and assembled into a rectangular frame as a whole. is there.
[0019]
As shown in FIGS. 14 and 15, the right vertical frame 33d is a thin profile material adapted to the width of the projecting ridge 36 which is bent in a U-shape, and is a ridge 36 facing the ends of the upper and lower horizontal frames 33b and 33c. , 36 are screwed (not shown) into the circular through-hole by screwing both ends together to form a rectangular assembly. By connecting the right vertical frame 33d, the glass mounting grooves in the upper and lower horizontal frames are connected. The ends of 37, 37 are opened (see FIG. 15) so that the glass 35 can be inserted from here.
[0020]
By the way, as described above, the shape material constituting the glass frame 33 is to form the horizontal frames 33b and 33c as the upper and lower side frames by bending both ends thereof at right angles around the left vertical frame 33a as one side frame. However, the corners 38, 38 formed by this bending do not form a right angle but have an arc shape. Therefore, when the glass 35 cut into a rectangular shape is inserted from the end of the mounting groove 37 and mounted, the corners of the right-angled glass do not fit in the arc-shaped corners 38, and as a result, the left vertical frame 33a and the side of the glass 35 There will be a gap between the edge and the edge.
[0021]
The above-mentioned problem can be solved by forming the corners of the glass 35 in an arc shape so as to match the corners 38. However, performing such pre-processing on the glass increases the cost and at the same time raises and lowers one side edge of the glass. Since the processing is performed only on both corners, the fitting of the glass 35 has directivity, which is inconvenient in handling.
Therefore, in the present invention, the bottoms of the glass mounting grooves 37, 37, which correspond to the two corners 38, 38, are cut along the length direction at the arcuate portions, and elongated protruding holes 39, 39 are formed to open the corners of the glass. The corners of the glass 35 formed in a rectangular shape are fitted exactly to the arc-shaped corners 38 of the glass frame.
[0022]
Reference numeral 40 in the figure denotes a rattling member attached to the upper and lower horizontal frames 33b and 33c to stop the glass 35 fitted in the glass frame from rattling. The play preventing member 40 is formed of a synthetic resin having elasticity, and has a mounting portion 40a having a U-shaped cross section as shown in the figure and a bifurcated arc-shaped spring extending from both ends of the mounting portion 40a. The mounting portion 40a is fitted so as to cover the ridge 36 of each horizontal frame, and a small projection 40c vertically extending from the lower surface thereof is pressed into a fitting small hole 41 provided on the upper surface of the ridge 36. The spring pieces 40b are inserted into the respective mounting grooves 37 along the length direction by this mounting.
[0023]
FIGS. 19 and 20 illustrate the mounting of the rattling member 40 and the prevention of rattling of the glass 35 by the rattling member in the lower horizontal frame 33c. When the glass 35 inserted from the end of the glass mounting groove 37 reaches the play preventing member 40 attached in the middle of the horizontal frame, the glass piece 35b lying in the groove 37 is crushed and penetrated, and the left vertical frame 33a is mounted. It is mounted by sliding until one side edge is fitted in the groove 37.
[0024]
The two glasses 35 are similarly inserted into the respective mounting grooves 37, crushing the spring pieces 40b of the respective rattling members 40, and being pressed against the side walls of the grooves by the repulsive force thereof, thereby being rattled. And the spacing between the glasses is maintained. The rattling member 40 is also attached to the upper horizontal frame 33b so as to oppose each other, and elastically stops vertically.
[0025]
By the way, in order to mount the backlash preventing member 40, in this embodiment, the width of each mounting groove 37 of the glass frame is formed to be wider than the thickness of the glass 35, so that the arc-shaped spring piece 40b can be easily formed together with the glass 35. It fits. Further, by expanding the width, the glass 35 can be easily fitted. At the same time, when the glass 35 is pressed from inside and outside, the spring piece 40b absorbs the force.
In particular, when the glass frame 33 is closed to the decorative frame 17, the edge 34a protruding toward the rear of the opening 34 is brought into contact with the front surface of the glass 35 in front of the glass frame 33 so that the spring piece 40b absorbs the pressure. In addition, if there is an error in the positional relationship between the edge 34a of the decorative frame 17 and the glass 35 that fits in the glass frame 33 in the closing operation, this error can be absorbed and it works effectively. Will be.
[0026]
In this embodiment, the backlash preventing member 40 is described with respect to an example in which a pair of spring pieces 40b are provided at both ends of the mounting portion 40a. Needless to say, it is also possible to omit one of the two spring pieces and insert one spring piece into the two mounting grooves 37 in parallel.
In addition, as described above, the rattling member 40 is used to prevent rattling caused by the difference between the thickness of the glass 35 fitted into the glass frame and the groove width of the mounting groove 37, and the glass frame is closed by the decorative frame 17. In order to prevent rattling caused by a closing error between the two when they are aligned, the mounting position, the number thereof, the number of spring pieces, and the like are appropriately selected in implementation.
[0027]
In the figure, reference numerals 42 and 43 denote pivot pieces for hinged the glass frame 33 to the decorative frame 17. This pivoting piece is formed by bending a strip-shaped metal piece into a crank shape, and is attached integrally to the outside of the corner portion 38 of the glass frame 33 using a rivet or the like. By attaching the pivot piece, the corner of the glass 35 protruding outside from the protruding hole 39 of the corner 38 is covered, and danger in handling is avoided (see FIG. 17).
[0028]
The glass frame 33 can be freely opened and closed by pivotally attaching the bearing pieces 42a, 43a of the pivot pieces 42, 43 to pivot shafts 44, 45 provided above and below the rear surface of the left edge 17b of the decorative frame 17, respectively. The pin 46 provided on the right vertical frame 33d on the free end side is engaged with the locking claw 47 so as to be held in a closed state.

[0031]
The keyhole decoration 54 is an attachment member for attaching the cylinder lock 56 to the front frame 1b for locking the front frame 1b to the machine frame 1a so as not to open the cylinder lock arbitrarily. This keyhole decoration is formed wider than the width of the key operation knob so that when the key is inserted into the keyhole of the cylinder lock from the front and unlocked, the decoration frame 17 can be freely opened and closed while the key is inserted. The cut-out portion 55 is formed in such a size that it receives the keyhole decoration 54 and at the same time does not generate an unnecessary gap therebetween.
[0032]
The keyhole decoration 54 is provided with a lens cover 57 having the same condition as the cover 28 on the front surface to give a sense of unity when the decoration frame 17 is closed. In the figure, reference numeral 58 denotes a rotating piece of the cylinder lock 56, which operates the locking hook 59 hooked to the machine frame 1a at the time of unlocking operation.
[0033]
On the other hand, as described above, the upper plate 18 has the shaft 22 mounted on the bearing hole 23 of the lower plate 14 and the shaft 21 pivotally mounted on the intermediate hinge piece 19 is fitted into the bearing hole 24 at the upper left end.

【The invention's effect】
Although the embodiment of the present invention has been described above, according to the present invention, since the glass frame main body is made of an extruded aluminum material, the mounting groove of the glass is formed into an appropriate width according to the thickness of the glass. Therefore, a high-precision glass frame can be provided, and an elastic play preventing member is interposed in the mounting groove to fill a gap between the glass and the side wall of the mounting groove. A simple glass frame can be provided.
Further, in the present invention, since the glass is pressed forward by the play preventing member, the glass frame is closed when the glass frame is closed and the glass is attached to the decorative frame, and there is a slight positional error between the two. However, since the backlash absorbing member absorbs this, stable closing can be obtained.
Further, since the play preventing member of the present invention is a molded product made of a synthetic resin, there is an advantage that it can be easily and inexpensively provided.
