Description

【０００１】
【発明の属する技術分野】
本発明は、パチンコ機の遊技盤を支持する遊技盤取付枠に関し、詳しくは、遊技盤前面の非遊技領域に配設される飾り縁枠の取り付け／取り外しを容易にする技術に関する。
【０００２】
【従来の技術】
パチンコ機では、一般に、遊技盤の前面中央に設定される遊技領域を取り囲む非遊技領域（外周スペース）に飾り縁枠を配置することによって装飾効果が高められている。
【０００３】
【発明が解決しようとする課題】
ところが、従来のパチンコ機が備える飾り縁枠は遊技盤の前面に対してビスや圧入等の手段でもって固定される構造である為、その取り付け作業や分解作業において、工具や機械等が必要で手間もかかっていた。
また、遊技盤を交換する際、飾り縁枠も必然的に交換しなければならず不必要なコストアップにつながっていた。
【０００４】
本発明は上記の事情に鑑みてなされたものであり、その目的とするところは、パチンコ機の遊技盤前面に配置する飾り縁枠の取り付け／取り外しを容易にすることであり、また、遊技盤交換時において飾り縁枠を再使用し易くすることである。
【０００５】
【課題を解決するための手段】
この課題は、前記の請求項に記載した構成のパチンコ機の遊技盤取付枠により解決される。なお、本明細書において、遊技盤前面のうち湾曲したパチンコ球誘導レールに囲まれる領域、すなわち障害釘や入賞口や役物などが配設されている部分を遊技領域といい、誘導レールの外側部分を非遊技領域という。
【０００６】
請求項１に係る発明では、遊技盤取付枠が備える飾り縁枠取付部に飾り縁枠を取り付けることで遊技盤前面の非遊技領域の所定の位置にあたかも直接被せたように飾り縁枠を配置することができる。すなわち、非遊技領域に飾り縁枠を配置して装飾効果を高め得る。なお、従来のように飾り縁枠を遊技盤に対し直接取り付けるものではないから、遊技盤を交換する場合において飾り縁枠を着脱する必要がなく、そのまま再使用することができる。また、飾り縁枠だけの交換もできるので簡単かつ安価に装飾効果（趣)を変えることが可能になると共に、飾り縁枠取付部に対して飾り縁枠をワンタッチ式に着脱可能に構成することが可能であるから、取り付け作業や分解作業において、工具や機械等が不要で作業性が向上する。さらに、飾り縁枠を分解することで外レールの取り替えも簡単にできるようになる。
また、飾り縁枠を遊技盤取付枠に取り付ける際に、先ず、飾り縁枠を第１の係合部を介して回動可能に支持し、続いてその飾り縁枠を遊技盤面に沿わせて所定の回転角度位置まで回転させたうえで第２の係合部を介して保持する。このように、互いに係合／離脱するときの動作方向が異なる第１及び第２係合部を有する着脱構造としたことで位置決め精度と信頼性を共に高め得る。なお、ここでいう第１と第２の各係合部は、互いに係合／離脱可能に形成されたもの（係合部）が飾り縁枠と遊技盤取付枠とにそれぞれ設けられて対をなす構成とされている。
【０００８】
請求項２に係る発明においては、突起が窪みにはまり込むことで所定の位置に位置決めされる。
【０００９】
【発明の実施の形態】
以下、本発明の実施形態を図に基づいて説明する。図１は遊技盤取付枠と飾り縁枠の取付構造を説明する分解斜視図である。同図に示す遊技盤取付枠１は、例えば合成樹脂で全体の形状が縦長の略矩形枠状に成形され、上下左右の周縁部分には多数の補強リブが設けられて軽量化と剛性向上が図られている。この遊技盤取付枠１の背面側に遊技盤２０がボルト等を利用した適宜な固定手段を介して取り付けられ、遊技盤前面の障害釘や入賞口や役物などが配設されている部分（遊技領域ともいう）を遊技盤取付枠１の開口部（くり抜き部）２から露出させるようになっている。
【００１０】
この遊技盤取付枠１の内側四隅のコーナー部には、飾り縁枠取付部（以下、単に「取付部」という）３ａ，３ｂ，３ｃ，３ｄが設けられており、詳しくは後述するが、ここに飾り縁枠３０，４０，５０を取り付けるようになっている。図中の６０は証紙貼付部３ｅに取り付けられる窓付きの飾り縁枠である。
なお、遊技盤取付枠１の前面側には、図示されていないが、遊技盤２０の盤面を被う透明ガラス板と電飾装置を有する保持枠、パチンコ球を貯留する上皿及び下皿、パチンコ球発射装置を操作するハンドル装置などが前面枠と共に配置されてパチンコ機が構成される。
【００１１】
本実施形態の場合、遊技領域を取り囲むようにセットされるパチンコ球誘導レールのうち、右下隅のパチンコ球発射装置から飛び出したパチンコ球が衝突して方向を変えるように遊技盤２０のほぼ左半面に配置する略円弧状の外レール７０が上記の飾り縁枠３０及び４０にて保持されるようになっている。
【００１２】
上記の飾り縁枠３０は、底部材３１にカバー部材３８を被せて一体化する構成とされ、底部材３１とカバー部材３８には両者を固定するための嵌合凹凸部と、外レール７０を挟み込んで保持するためのレール保持部とが形成されている。
上記の飾り縁枠４０は、底部材４１にカバー部材４８を被せて一体化する構成とされ、底部材４１とカバー部材４８には両者を固定するための嵌合凹凸部と、外レール７０を挟み込んで保持するためのレール保持部とが形成されている。
この場合、外レール７０は飾り縁枠３０と４０とにより中央部分を若干残して両側部分が保持されるので、飾り縁枠３０と４０の固定前においては外レール７０の中央部分を弾性限度内で曲げることが可能である（図８参照）。
また、飾り縁枠５０は、底部材５１にカバー部材５８を被せて一体化する構成である。
なお、これらの飾り縁枠３０，４０，５０には、ランプを内蔵させて装飾効果を一層高めるようにするのが好ましい。
【００１３】
次に、上記の飾り縁枠３０，４０，５０の取付構造について説明する。図２は遊技盤取付枠の左上部分を拡大して示す正面図、図３は図２のＩＩＩ−ＩＩＩ線断面を斜めにして見た図である。図１〜図３に示すように、遊技盤取付枠１の各取付部３ａ〜３ｄは遊技盤２０の盤面と平行に延びる薄板状に形成されており、遊技盤取付枠１が遊技盤２０を所定の位置に支持したときに、各取付部３ａ〜３ｄの背面側が遊技盤２０の前面、詳しくは遊技盤２０の非遊技領域と接触もしくは近接する位置にくるように設定されている。
【００１４】
そして、各取付部３ａ〜３ｄと、対応する各飾り縁枠３０，４０，５０とには互いに係合／離脱可能に形成されて対をなす係合部がそれぞれ設けられ、飾り縁枠３０，４０，５０を遊技盤取付枠１の前面側からワンタッチ式に着脱することができるようになっている。この係合部の構成について、左上の取付部３ａと飾り縁枠３０を例にとって詳しく説明することにする。
【００１５】
先ず、取付部３ａ側の係合部について説明すると、取付部３ａには係合穴４と、係合片５及び６とが形成されている。この係合片５及び６は、図３及び図７参照、取付部３ａから基部５ａ，６ａが隆起し、その基部５ａ，６ａから係止梁部５ｂ，６ｂが取付部３ａ前面（飾り縁枠取付面）との間に板部材を差し込み可能なように略一定の間隔を隔てた位置に片持ち梁状に延び、かつ、係止梁部５ｂ，６ｂの背面側の所定の位置には略半球形状の突起５ｃ，６ｃが取付部３ａとの隙間を狭める方向に突設されてなる構成である。なお、取付部３ａには、係合片５及び６の真下にその係合片５及び６とほぼ同一形状の窓孔５ｄ，６ｄが形成されているが、これは成形を容易にするためのものである。
【００１６】
次に、飾り縁枠３０側の係合部について説明する。図４は飾り縁枠３０の底部材３１を示す平面図である。飾り縁枠３０は、図１参照、略板状の底部材３１の底面（背面）を取付部３ａに当接させるようになっており、この底部材３１には取付部３ａに直交する方向、すなわち遊技盤２０の盤面垂直方向に延びて前記係合穴４に回動自在に嵌合する棒状の係合突部３２（図４及び図８参照）と、図示形状の孔部３３，３４が形成されている。孔部３３，３４は、それぞれ、前記係止梁部５ｂ，６ｂの平面形状より僅かに大きな略矩形の孔部３３ａ，３４ａと、前記基部５ａ，６ａの断面形状に対応する大きさの孔部（あるいは溝）３３ｂ，３４ｂとが連設された状態に形成されている。孔部３３，３４は本例のような貫通孔のほか、適宜形状の窪みであっても良い。
【００１７】
さらに、底部材３１には、孔部３３，３４近傍の所定位置に、前記突起５ｃ，６ｃに対応する大きさの孔部もしくは窪み３５，３６が形成されている（図７参照）。図中の３７は、前記外レール７０を保持するための段付部（保持部）であり、このほかに、カバー部材３８を取り付けるための嵌合凹凸部が形成されている。なお、底部材３１とカバー部材３８の連結に、ボルトナット等の適宜な締結具を用いることにしても構わない。
【００１８】
ここで、取付部３ａと底部材３１の両係合部の作用について説明する。図５は、係合の第１ステップを説明する図である。すなわち、底部材３１に設けられた係合突部３２が取付部３ａの係合穴４にはめ込まれ、底部材３１の孔部３３ａ，３４ａに対しては取付部３ａ側の係合片５及び６がはまり込んでいる。この状態において、底部材３１の底面（背面）が取付部３ａの上面（取付面）に当接し、底部材３１は係合突部３２の軸線回りに回動自在な状態で支持されているが、軸線方向、すなわち、取付部３ａに対して垂直に引っ張ると係合突部３２が抜けて係合関係が解除される。この係合突部３２と係合穴４が対をなして、本発明でいうところの第１の係合部を構成している。
【００１９】
続いて、係合の第２ステップとして、底部材３１を係合突部３２の軸線回りに反時計方向に回動させれば、図６及び図７に示すように、係合片５，６の基部５ａ，６ａと孔部３３ｂ，３４ｂが係合し、突起５ｃ，６ｃが窪み３５，３６にはまり込むことで所定の位置に位置決めされる。このように、底部材３１の一部（孔の縁部）が係合片５，６の係止梁部５ｂ，６ｂの下側に潜り込んだ状態になって抜け止めがなされるので、底部材３１がしっかりと保持され、一方向の動きだけでは簡単に外れない。上記の係合片５，６と底部材３１とを係合／離脱させる構成、具体的には、基部５ａ，６ａと孔部３３ｂ，３４ｂ、及び突起５ｃ，６ｃと窪み３５，３６がそれぞれ対をなして、本発明でいうところの第２の係合部を構成している。
【００２０】
飾り縁枠３０と取付部３ａにそれぞれ設けられた係合部は上記のように構成されている。なお、飾り縁枠４０，５０と取付部３ｂ，３ｃの係合関係も上記と同様の構成であり、取付部３ｂには係合穴７と係合片８，９が形成され、取付部３ｃには係合穴１１と係合片１２，１３，１４が形成されている。他方、飾り縁枠４０の底部材４１には孔部４３，４４が形成され、飾り縁枠５０の底部材５１には孔部５３，５４，５５が形成され、底部材４１には係合突部４２が形成され、さらに、カバー部材５８には係合突部５２が形成されている。各係合部の作用は前述したのとほぼ同様である。
【００２１】
次に、上記の係合部構成を有する、飾り縁枠３０，４０，５０の着脱操作について説明する。飾り縁枠３０及び４０は、図８に示すように、それぞれ一体に組み立てられ外レール７０を保持して連結しているものとする。
先ず、図９に示すように、外レール７０を若干内側に折り曲げるようにして飾り縁枠３０と４０を取付部３ａ，３ｂにあてがう。そして、前述したように、係合突部３２，４２を対応する係合穴４，７にはめ込むとともに、係合片５，６，８，９をそれぞれ対応する孔部３３，３４，４３，４４にはめ込んだ状態にする。これで底部材３１，４１の底面（背面）と取付部３ａ，３ｂの前面（取付面）とが当接する。
【００２２】
その後、飾り縁枠３０と４０を上下に押し開くようにして取付部３ａ，３ｂに沿わせて係合突部３２，４２の軸線回りに回転させると、前述したように、取付部３ａ，３ｂ側の係合部に対し底部材３１，４１側の係合部が係合することで両飾り縁枠３０，４０が所定の位置に保持される。
また、飾り縁枠６０を証紙貼付部３ｅに取り付け、さらに、図１０に示すように、向かって右側の飾り縁枠５０を係合穴１１にはめ込んだ後、係合突部５２の軸線回りに回転させることで取り付けを終える。
この状態が図１１に示されている。
【００２３】
なお、取り外す場合は、取付時とは反対方向に各飾り縁枠を動かせば良い。
このように、各飾り縁枠は、工具を用いずとも簡単かつ迅速に遊技盤取付枠の取付部に着脱することができる。さらに、飾り縁枠３０，４０を底部材３１，４１とカバー部材３８，４８とに分解することで外レール７０の取り替えが簡単にできる。
【００２４】
【発明の効果】
本発明によれば、パチンコ機の遊技盤前面に配置する飾り縁枠の取り付け／取り外しが容易になり、ひいては、遊技盤交換時において飾り縁枠を再使用し易くなる。
