Description

【０００１】
【産業上の利用分野】
本発明はパチンコ機において、景品球タンクの球を整列して景品球払出装置へ導くタンクレールの取付構造に関するものである。
【０００２】
【従来の技術】
従来、この種のタンクレールの取付構造は、例えば図２１に示すようにタンクレール１００の周側縁に長孔状のねじ挿通孔１０１を有する袋状の取付部１０２を数多く設け、一方、タンクレール１００を取付ける機構板１０３には前記取付部１０２に対応させて同数の突起１０４を形成し、タンクレール１００の各取付部１０２を機構板１０３の各突起１０４にそれぞれ合致させた状態でビス１０５を取付部１０２のねじ挿通孔１０１から突起１０４に螺締することにより取付けるようにしていた。そして、タンクレール１００の傾斜勾配を変更する場合には、全てのビス１０５を緩めてねじ挿通孔１０１の範囲内で角度調節した後再びビス止めするようにしていた。
【０００３】
【発明が解決しようとする課題】
前記のように従来のパチンコ機におけるタンクレールの取付構造にあっては、多くのビスを締着しなければならず、その取付けに時間と手間が掛かって作業能率を著しく低下させており、タンクレールの傾斜勾配の変更作業も容易でなかった。また、パチンコ機において、現状では、この種のタンクレールの取付けを含む裏部品の組付けに際しては多数のビス止め作業が必要とされており、作業能率の向上及び製造上のコストダウンを図るために１本でもビス止め作業を減らすことが重要な課題とされている。
【０００４】
そこで、本発明は、上記課題を解決すべくなされたものであり、ビス止めを極力少なくし、しかも簡単な構造でタンクレールを確固と取り付けることができるパチンコ機におけるタンクレールの取付構造を提供することを目的としている。
【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、本発明のパチンコ機におけるタンクレールの取付構造は、遊技盤の裏面に景品球タンク，該景品球タンクの球を整列して景品球払出装置へ導く樋状のタンクレール等を組付けた機構板を配設してなるパチンコ機において、機構板の外側表面に当接するタンクレールの下流側に位置した後側壁に嵌合突子を設けると共に、上流側に位置した後側壁のみに長孔状のねじ挿通孔を有する袋状の取付部を設け、一方機構板にはタンクレールの下流側に位置させて嵌合突子を受容する受部を設けると共に、タンクレールの上流側に位置させて取付部に合致する突部を設け、また、タンクレールの下端側縁に位置させて機構板の前面に該機構板の前面との間に後側壁の肉厚とほぼ等しい挿入間隔が形成される側面逆Ｌ字型の受止片を設け、タンクレールの嵌合突子を受部に受容させると共にタンクレールの後側壁の下端側縁を受止片と機構板の前面間に差し込み、更に、取付部を突部に合致させ、ねじ挿通孔を介してビスを突部に螺締することによってタンクレールを機構板に取付けるようにした構成からなるものである。
【０００６】
または、遊技盤の裏面に景品球タンク，該景品球タンクの球を整列して景品球払出装置へ導く樋状のタンクレール等を組付けた機構板を配設してなるパチンコ機において、機構板の外側表面に当接するタンクレールの下流側に位置した後側壁に嵌合突子を設けると共に、上流側に位置した後側壁のみに長孔状のねじ挿通孔を有する袋状の取付部を設け、一方、機構板にはタンクレールの下流側に位置させて嵌合突子を受容する受部を設けると共に、タンクレールの上流側に位置させて取付部に合致する突部を設け、タンクレールの嵌合突子を受部に受容させると共に、取付部を突部に合致させ、ねじ挿通孔を介してビスを突部に螺締することによってタンクレールを機構板に取付けるようにし、更にタンクレールの上流側に位置する機構板に突起を設け、一方タンクレールの上流側に位置した後側壁の裏面に前記突起に嵌合し得る凹溝を設け、該凹溝を突起に嵌合するか又はタンクレールの後側壁の下縁部を突起で受けることによりタンクレールの傾斜勾配を変更可能なようにした構成からなるものである。
【０００７】
【作用】
タンクレールの嵌合突子を機構板の受部に受容させると共に、ねじ挿通孔を有する取付部に突部を合致させ、ねじ挿通孔を介してビスを突部に螺締する。これによりタンクレールが機構板に確固と組付け固定される。
【０００８】
また、タンクレールの傾斜勾配を変更するには、ビスを緩めておき、タンクレールの上流側を手で持って上方へ回動するようにひねりを与える。これにより機構板とタンクレールの後側壁とが僅かに離間し、突起と凹溝との係合が外れる。この状態で、タンクレールの上流側を上方へ押し上げ、後側壁の下縁部を突起で受けさせる。
【０００９】
【実施例】
以下、図面を参照して本発明の一実施例について説明する。図１は本発明が適用されるパチンコ機の裏面図であり、１はパチンコ機の前面枠、２は前面枠１の裏面に着脱自在に取付けられる遊技盤、３は遊技盤２の裏面に開閉自在に装着される合成樹脂製の機構板である。この機構板３の裏面上部には景品球タンク４が固着される。景品球タンク４の下方には、該景品球タンク４の球を整列して導き出すタンクレール５が設けられる。タンクレール５の下流端は、球圧を弱めるための屈曲レール６を介して景品球払出装置７に接続されている。従って、景品球タンク４の球は、タンクレール５、屈曲レール６により整列されながら景品球払出装置７に連続して導かれることになる。
【００１０】
図２は本実施例の特徴となるタンクレール５の取付構造を説明するため、該タンクレール５を機構板３から分離して示す要部斜視図、図３はタンクレール５の裏面斜視図である。タンクレール５は、機構板３の外側表面に当接する後側壁８と底部９および前側壁１０とにより上面開放の樋状に形成されると共に、底部９に仕切壁９ａ，９ａを設けて長手方向に３条の球通路１１（図７参照）が形成されている。なお、本発明は、図示しないが球通路１１が２条のタンクレールにも同様に適用することができる。
【００１１】
しかして、前記タンクレール５の上流側に位置する後側壁８の側縁部前面に１つの取付部１２が形成されている。該取付部１２は図５に示すように後面が開放した袋状を成し、その前面に長孔状のねじ挿通孔１３を貫設している。また、取付部１２の下方には後側壁８の裏面に横長の凹溝１４が形成され、更に、タンクレール５の下流端近くの下側縁部には先端が半円形状に形成された嵌合突子１５が突設されている。
【００１２】
一方、機構板３には、タンクレール５の上流側に位置させてその前面に取付部１２に合致する突部１６を突設し、その下方に凹溝１４に嵌合する突起１７が突設されている。また、タンクレール５の下流側に位置させて機構板３に嵌合突子１５が差し込まれる差込孔１８が開設され、その裏面にＵ字型（図６参照）をなして差込孔１８の下部を囲い嵌合突子１５を受容する受部１９が設けられる。該受部１９の内側中心には嵌合突子１５の軸孔２０が嵌着する軸支ピン２１が突設されている。更に、タンクレール５の下端側縁に位置させて、機構板３の前面に受止片２２，２２が形成されている。これら受止片２２，２２は機構板３の前面との間に挿入間隔Ｌが形成されるように側面から見て逆Ｌ字型（図７参照）に形成される。そして、この挿入間隔Ｌは後側壁８の肉厚とほぼ等しく形成される。
【００１３】
そこで、このような構成からなる本発明において、タンクレール５を機構板３に取付けるには、図６に示すように、タンクレール５の嵌合突子１５を機構板３の差込孔１８に差込むと共に軸支ピン２１に軸孔２０を嵌着した状態で、受部１９に受容させる。更に、図７に示すようにタンクレール５の後側壁８の下端側縁を各受止片２２，２２と機構板３の前面間に差し込むと共に、図５に示すようにタンクレール５の取付部１２を機構板３の突部１６と合致させ、ねじ挿通孔１３からビス２３を突部１６に螺合する。
【００１４】
このように、ビス止め個所が１個所のみでタンクレール５が機構板３に取付けられる。この際、機構板３の突起１７がタンクレール５の凹溝１４に係合し、更にタンクレール５の嵌合突子１５に開設された軸孔２０が軸支ピン２１に嵌着することにより正確な位置づけ及び保持機能が与えられる。
【００１５】
また、本発明のタンクレールの取付構造は、図４鎖線で示すようにタンクレール５の傾斜勾配を容易に変更することが可能である。このタンクレール５の傾斜勾配の変更は基本的には合成樹脂の弾性を利用して行うもので、タンクレール５が取付けられた状態においてビス２３を緩め、タンクレール５の上流側を手で持って上方へ回動するようにひねりを与える。これによって、機構板３とタンクレール５の後側壁８とが僅かに離間し、突起１７と凹溝１４との係合を外すことが可能となる。そして、突起１７と凹溝１４との係合を外した状態で図４鎖線のようにタンクレール５の上流側を上方へ押上げ、さらに図８に示すように後側壁８の下縁部を突起１７で受けさせることにより達せられる。
【００１６】
図９乃至図１３はタンクレールの取付構造の他の実施例を示すもので、この実施例によれば、タンクレール５１の上流側に位置する後側壁８１の後縁部前面に２つの取付部１２，１２が形成され、該各取付部１２，１２には、本発明と同様に長孔状のねじ挿通孔１３が貫設されている。また、タンクレール５１の下流端近くの下側縁部に先端が半円形状に形成されると共に、軸孔２０を有する嵌合突子１５が突設されている。
【００１７】
一方、機構板３１には、タンクレール５１の上流側に位置させてその前面に前記２つの取付部１２，１２に合致する突部１６，１６が突設され、また、タンクレール５１の下流側に位置させて機構板３１の前面に嵌合突子１５が受容される受部１９１が設けられている。該受部１９１は上面が開口したポケット状に形成され、内側面に嵌合突子１５の軸孔２０が嵌着される軸支ピン２１が突設されている。更に、タンクレール５１の下端縁に位置させて、機構板３１の前面に本実施例と同様に受止片２２，２２が形成されている。
【００１８】
そこで、タンクレール５１を機構板３１に取付けるには、図１２に示すように、タンクレール５１の嵌合突子１５を、軸支ピン２１に軸孔２０を嵌着した状態で、受部１９１に受容させる。更に、タンクレール５１の後側壁８１の下端側縁を各受止片２２，２２と機構板３１の前面間に差し込むと共に、図１３に示すようにタンクレール５１の各取付部１２，１２を機構板３１の突部１６，１６と合致させ、ねじ挿通孔１３からビス２３を突部１６に螺合する。
【００１９】
このように、ビス止め個所が２個所のみでタンクレール５１が機構板３１に取り付けられる。なお、この実施例では本実施例の如く突起１７と凹溝１４は設けられてないが、前記の通り２個所をビス止めすれば保持機能は充分達せられるからである。また、タンクレール５１の傾斜勾配の変更は２つのビス２３，２３を緩めてタンクレール５１の上流側を手で持って上方へ回動し、ねじ挿通孔１３，１３の長さ範囲内で適宜位置で止め再び前記ビス２３，２３を螺締することにより行う。
【００２０】
ところで、タンクレール５は、景品球タンク４と屈曲レール６を取り付けた後に、機構板３に取付けるようにしているが、この際、前記景品球タンク４や屈曲レール６の一部形状が邪魔して機構板３の正面側から取付けできない場合がある。
【００２１】
そこで、特にタンクレールを横方向からスライドさせて取り付けるようにした他の実施例を図１４乃至図２０に基づいて説明する。この実施例によれば、タンクレール５２の上流側に位置する後側壁８２の側縁部裏面に長孔状のねじ挿通孔１３を有する取付部１２が設けられると共に、その下方に係止凸部２４が設けられている。また、タンクレール５２の下流端近くの下側縁部に先端が半円形状に形成されると共に、軸孔２０を有する嵌合突子１５が突設され、また、その一側に横長のガイド溝２５が形成されている。更に、後側壁８２の下縁部には複数の係止孔２６，２６，２６が開設される。
【００２２】
一方、機構板３２には、タンクレール５２の上流側に位置させてその前面に凹窪部２７を形成すると共に、該凹窪部２７にねじ挿通孔１３と合致するねじ孔２８が設けられ、その下方に係止凸部２４が嵌合する複数の係止凹部２９，２９，２９が設けられている。また、タンクレール５２の下流側に位置させて機構板３２の前面に嵌合突子１５が受容される受部１９２が設けられる。該受部１９２は上面とタンクレール５２の上流側の側部が開口したポケット状に形成され、内側面に嵌合突子１５の軸孔２０が嵌着される軸支ピン２１が突設されている。また、受部１９２の一側にガイド溝２５に嵌入する突条３０が設けられている。
【００２３】
更に、機構板３２には、タンクレール５２の係止孔２６，２６，２６にそれぞれ対応する係止片３３，３３，３３が形成される。該各係止片３３，３３，３３は、後側壁８２の裏面との間に挿入間隔Ｌが形成されるように平面から見てＬ字型（図１８参照）に形成される。そして、これら挿入間隔Ｌは機構板３２の肉厚とほぼ等しく形成される。
【００２４】
そこで、タンクレール５２を機構板３２に取り付けるには、まず、図１７に示すように嵌合突子１５を受部１９２の側部に臨ませると共に、ガイド溝２５に突条３０を嵌入し、更に、各係止片３３，３３，３３に各係止孔２６，２６，２６を合致させる。次いで、タンクレール５２を横方向（図１６において右方向）にスライドさせ、図１７に示すように嵌合突子１５を軸孔２０が軸支ピン２１に嵌着された状態で、受部１９２に嵌合して受容する。これに伴い、図１８に示すように各係止片３３，３３，３３が各係止孔２６，２６，２６に係止され、更に図１９に示すように凹窪部２７内に取付部１２が嵌入して、ねじ孔２８と合致するねじ挿通孔１３からねじ孔２８にビス２３を螺締することにより、タンクレール５２が横方向からスライドさせることにより機構板３２に取り付けられる。
【００２５】
タンクレール５２のスライドの際には、図２０に示すようにガイド溝２５に突条３０が嵌入しているので、方向性が安定し取り付け易い。また、この実施例においてもタンクレール５２の傾斜勾配を容易に変更することが可能である。すなわち、ビス２３を緩めた状態で、図１６鎖線で示すようにタンクレール５２の上流側を手で持って上方へ回動するようにひねりを与える。これによって、機構板３２とタンクレール５２の後側壁８２とが僅かに離間し、係止凸部２４と係止凹部２９との係合位置が変えられる。そして、再びビス２３を螺締すれば良い。なお、図示は省略するが、この実施例において、タンクレール５２の係止孔２６と機構板３２の係止片３３を逆に設けるようにしても良い。更に、本実施例と他の実施例の相互間において、例えば嵌合突子と受部、突起と凹溝及び係止凸部と係止凹部の各組み合わせ同志を交換するようにしても良い。
【００２６】
【発明の効果】
以上説明したように、本発明に係るパチンコ機におけるタンクレールの取付構造は、簡単な構造であり、しかも僅かなビス止めによりワンタッチ操作でタンクレールを機構板に取付けることができ、作業性の向上、低コスト化等に優れた効果を発揮する。また、タンクレールの傾斜勾配の変更も容易にできると共に、タンクレールの取付け状態を確実かつ安定的に維持することができる。

FIG. is there. The tank rail 5 is formed in a gutter shape having an open top surface by a rear side wall 8 and a bottom portion 9 and a front side wall 10 which are in contact with the outer surface of the mechanism plate 3, and is provided with partition walls 9 a, 9 a on the bottom portion 9 in the longitudinal direction. Are formed with three ball passages 11 (see FIG. 7). Although not shown, the present invention can be similarly applied to a tank rail having two ball passages 11.
[0011]
Thus, one mounting portion 12 is formed on the front surface of the side edge of the rear side wall 8 located on the upstream side of the tank rail 5. As shown in FIG. 5, the mounting portion 12 has a bag shape with an open rear surface, and has a long hole-like screw insertion hole 13 penetrating the front surface thereof. A horizontally elongated groove 14 is formed on the back surface of the rear side wall 8 below the mounting portion 12, and a lower end near the downstream end of the tank rail 5 has a semicircular tip. The joint 15 is protruded.
[0012]
On the other hand, the mechanism plate 3 is provided with a projection 16 which is located on the upstream side of the tank rail 5 and which matches the mounting portion 12 on the front surface thereof, and a projection 17 which fits into the concave groove 14 is provided below the projection 16.

Further, receiving pieces 22, 22 are formed on the front surface of the mechanism plate 3 at the lower end side edge of the tank rail 5. These receiving pieces 22, 22 are formed in an inverted L-shape (see FIG. 7) when viewed from the side so that an insertion interval L is formed between the receiving pieces 22, 22 and the front surface of the mechanism plate 3. The insertion interval L is formed substantially equal to the thickness of the rear side wall 8.
[0013]
Therefore, in the present invention having such a configuration, in order to attach the tank rail 5 to the mechanism plate 3, the fitting projection 15 of the tank rail 5 is inserted into the insertion hole 18 of the mechanism plate 3 as shown in FIG. With the shaft hole 20 fitted in the support pin 21 while being inserted, the receiving portion 19 receives the shaft hole 20. Further, as shown in FIG. 7, the lower end side edge of the rear side wall 8 of the tank rail 5 is inserted between each of the receiving pieces 22, 22 and the front surface of the mechanism plate 3, and as shown in FIG. 12 is matched with the protrusion 16 of the mechanism plate 3, and a screw 23 is screwed into the protrusion 16 through the screw insertion hole 13.
