【発明の属する技術分野】
本発明はパチンコ機やスロットマシン等の遊技機の遊技機枠に関する。
【０００２】
【従来の技術】
固定枠とこの固定枠に対してヒンジを介して片開き開閉可能に取付けられるとともにパチンコ機の遊技盤、スロットマシンの回胴表示装置を含む遊技主体技を搭載した可動枠とを備えた遊技機枠において、可動枠の下端部に回転体すなわちローラ付きスライダー装置を設け、固定枠の下枠上面に案内板又は滑り板等の受け面を設け、可動枠が開閉される際にスライダー装置のローラが受け面上を転がるように構成することにより開閉動作を円滑に行えるようにしたものが知られている（例えば、特許文献１，２参照）。また、ローラを可動腕で保持し、可動腕のてこ動作により可動枠を迫り上げる構造のものも知られている（例えば、特許文献３参照）。

【発明が解決しようとする課題】
しかしながら、上記特許文献の遊技機枠では、スライダー装置におけるローラがその外周で受け面上に接触して支持する構成となっているため、可動枠を閉じた状態において遊技盤，貯球タンク，球樋、制御装置，電源装置等で構成される遊技主体を搭載した可動枠の重量（２０Ｋｇ程度である）がローラを介して受け面に加わるので、可動枠の開閉を繰り返すうちにローラの外周と線接触する受け面が次第に窪んできてしまい、これにより可動枠が垂れ下がってしまうという課題があった。特に特許文献３の場合は、ローラを支点として可動枠を迫り上げており、可動枠の重量がローラを介して受け面に加わりやすい構造のために、可動枠が垂れ下がってしまうという問題が顕著に生じる。
本発明は、可動枠の垂れ下がり、即ち、可動枠の片下がりを少なくできる構造を備えた遊技機枠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】
本発明は、固定枠と、この固定枠に対して開閉可能に取付けられるとともに遊技主体を搭載する可動枠とを備えた遊技機枠において、上記固定枠の下部に設けられた下枠の上面に取付けられた金属板により形成された受け面と、上記可動枠の下端部裏面に形成された凹部内に収納された収納部と、この収納部の両側より同方向に延長し上記可動枠の下端部の裏面に対向して設けられて上記収納部を上記可動枠の下端部の裏面に取付ける一対の取付部と、上記収納部の下部に設けられて上記可動枠の裏側に突出する一対の回転体支持部材と、上記一対の回転体支持部材に取付けられて上記可動枠の開閉に伴い上記受け面上を回転する回転体と、上記回転体支持部材の基端部の下部に設けられて上記可動枠が上記固定枠に対して閉じられた場合に下面が上記受け面上に接触する当接面部とを備え、当該当接面部の下面は上記回転体の外周下面よりも下方に設けられ、上記収納部と上記取付部と上記回転体支持部材と上記当接面部とが同じ一枚の金属板材が折曲されて形成されるとともに、上記受け面の前縁には回転体又は当接面部を受け面上に案内する案内部が形成されたので、遊技主体を搭載した可動枠の重量を当接面部を介して受け面の面で受けることができることから、経時による受け面の窪みを少なくでき、可動枠の垂れ下がり（片下がり）を少なくできる。特に、上述したように、当接面部の下面を回転体の外周下面よりも下方に設けたことにより、当接面部が受け面に接触した状態において回転体の外周が受け面に接触せず、可動枠が閉じられた場合に回転体と受け面とが線接触しないので、回転体と受け面とが線接触することによる経時的な受け面の窪み発生のおそれを少なくできる。
また、上述したように、受け面を固定枠の下枠の上面に取付けられた金属板により形成したので、可動枠の重量を受ける受け面を簡単かつ強固に形成できる。
また、上述したように、一枚の金属板材が折曲されて収納部と取付部と当接面部と回転体支持部材とが形成されたものとしたので、当接面部と回転体支持部材の強度を向上できる。
また、上述したように、受け面の前縁には回転体又は当接面部を受け面上に案内する案内部が形成されたものとしたので、回転体や当接面部が案内部を介して受け面上にスムーズに乗り上がるので、可動枠を開閉する際に要する人力を軽減することができる。
【０００６】
【発明の実施の形態】
図を参照し、本発明の実施形態による遊技機枠１を説明する。図１は可動枠２を開いた遊技機枠１を示す斜視図、図２はスライダー装置９の外観を示す斜視図、図３はスライダー装置９の分解斜視図、図４はスライダー装置９の本体の展開図、図５はスライダー装置９の動作説明図である。
【０００７】
図１は遊技機枠１の可動枠２を固定枠３から開放し、その裏面２’側を見せるように描いている。図１に示すように、遊技機枠１は、図外の遊技盤，貯球タンク，球樋、制御装置，電源装置等で構成される遊技主体を搭載する可動枠２が遊技店の島に取付けられる額縁状の固定枠３に上下の枠ヒンジ４，４’の支軸４ａ，４ｂを支点として矢印Ａ，Ｂに示すように前方横方向に片開き可能に取付けられて成る。可動枠２の前面には遊技盤の遊技領域に対向する図外の透過性パネルが片開き開閉可能に取付けられ、また、図外の前面飾り等が取付けられている。
固定枠３は上枠２９、下枠３０、上枠２９と下枠３０とをその両端で結合する右横枠３３及び図外の左横枠を備えて構成される。また、固定枠３の下枠３０の前側には化粧板３００が取付けられている。可動枠２及び固定枠３は木枠により形成されている。可動枠２の自由端側縦縁には施錠装置５が配置される。施錠装置５及び可動枠ロック機構６は可動枠２の裏面２’に固定されたリアプレート８に取付けられる。リアプレート８は可動枠２との間にパチンコ機の遊技盤やパチンコ玉を遊技媒体として用いるスロットマシンの回胴表示装置を収納するための空間を形成する。そして、可動枠２が矢印Ｂ方向に回動され、固定枠３に取付けられている状態において、図外のキーが人為操作で施錠装置５に可動枠２の前側より差込まれて一方向に例えば９０度回転操作されると、可動枠２の裏面２０に設けられた可動枠ロック機構６の可動枠ロックレバー６ａが固定枠３に設けられた可動枠止具７より外れる。これにより、可動枠２が固定枠３に対して矢印ＡＢ方向に開閉可能となる。可動枠ロックレバー６ａが可動枠止具７より外れた状態のまま、可動枠２が人為操作で前側に引かれることにより枠ヒンジ４，４’を中心として矢印Ａに示す横方向前側に片開きされる。また、可動枠２が開かれた状態から可動枠２が人為操作で矢印Ｂに示す裏側に向けて押されることにより、可動枠ロックレバー６ａの先端フックが可動枠止具７を超えて、可動枠ロックレバー６ａが可動枠ロック機構６に内蔵されたばね力で元の位置に戻り可動枠止具７に係合する。これにより、可動枠２は固定枠３に対して開閉不能となる。
【０００８】
図１〜５を参照し、スライダー装置９について説明する。スライダー装置９は、可動枠２の自由端側寄りで、かつ下端部２１の裏面２０に取付けられ、本体９０と回転体としてのローラ９９とを備えて構成される。本体９０は、可動枠２の下端部２１の裏面２０に形成された凹部２２に収納される収納部９１と、この収納部９１の両側より同方向に延長し可動枠２の下端部２１の裏面２０に対向して当該裏面２０に取付けられる取付部９２，９２’と、収納部９１の下部に設けられ可動枠２の裏側に突出するローラ支持部材（回転体支持部材）９３，９３’と、ローラ支持部材９３，９３’の基端部９３ａ，９３’ａの下部に設けられた当接面部９４とで構成される。ローラ９９は、ローラ支持部材９３，９３’の先端部９３ｂ，９３’ｂに形成された軸支持孔９５，９５’に装着される回転支持軸９６を介して回転可能に取付けられる。固定枠３の下枠３０及び化粧板３００の上面３１には止めねじ３２等により金属板１０が下枠３０及び化粧板３００にまたがって取付けられ、ローラ９９は可動枠２の開閉に伴い金属板１０の上面１１（受け面）上を転がり、当接面部９４は可動枠２が固定枠３に対して閉じられる場合に金属板１０の上面１１に接触し可動枠２の重量を金属板１０の上面１１（受け面）で受けさせるものである。
上記当接面部９４は少なくとも金属板１０の上面１１との当接面９４ｃがローラ９９の外周下面９９ａより０．１ｍｍ〜１．０ｍｍ程度下方に位置するよう形成されている。そして、この構成により、可動枠２は固定枠３に固定されているときは、スライダー装置９の当接面部９４の当接面９４ｃにより、金属板１０の上面１１上で面状に支持される。
本体９０は図４に示すように一枚の金属板材１００を折曲して形成される。即ち、一枚の金属板材１００を折曲して当接面部９４とローラ支持部材９３，９３’とを形成したので、当接面部９４とローラ支持部材９３，９３’の強度を向上できる。
また、金属板１０の前縁にはローラ９９や当接面部９４を金属板１０の上面１１に案内するための円弧面や斜面等による案内部１２が形成されている。
以上の構成から成るスライダー装置９は、可動枠２の下端部２１の裏面２０に形成された凹部２２に収納部９１を収納し、取付部９２，９２’に形成された取付け孔９２ａを介して可動枠２の下端部２１の裏面２０に止めねじ２３等で取付けられる。尚、ローラ９９は両側のローラ支持部材９３，９３’により回転支持軸９６を介して両支持状態に支持され、回転支持軸９６が離脱しないように回転支持軸９６の先端には止め輪９７が取付けられている。また、ローラ支持部材９３には可動枠２の下端部２１の裏面２０に形成された位置決め突起２４に係合する位置決め孔９２ｂを備え、スライダー装置９の本体９０の可動枠２への位置決めを容易にしている。
【０００９】
次にスライダー装置９の動作を説明する。可動枠２を固定枠３側に閉じる場合、まず、図５（ａ）のように矢印Ｂ方向に可動枠２を移動させ、その移動に伴ってローラ９９が案内部１２を介して矢印Ｃ方向に回転しつつ金属板１０の上面１１に案内されて乗り上がる。そして、図５（ｂ）のようにローラ９９が金属板１０の上面１１（受け面）上を矢印Ｃ方向に転がりながら可動枠２は更にＢ方向に進み、当接面部９４の後端９４ａの下縁９４ｂが案内部１２をすべりながらスライドして金属板１０上に乗り上げ、更に図５（ｃ）のように当接面部９４が完全に金属板１０の上面１１に乗り上がって当接面９４ｃと接触し、ローラ９９の外周面９９ａは金属板１０の上面１１（受け面）より離れて可動枠２が固定枠３内に収納されて閉じる。従って、可動枠２が固定枠３に対して閉じられる場合において、当接面部９４がその当接面９４ｃを金属板１０の上面１１に接触させて乗り上げ、かつ、ローラ９９の外周面９９ａは金属板１０の上面１１より離れるので、金属板１０とスライダー装置９との接触は当接面部９４を介した面接触となり、遊技主体を搭載した可動枠２の重量を面で受けて支えることができることから、従来のようにローラと受け面とが線接触する構造に比べて、経時による金属板１０の上面１１（受け面）の窪みを少なくでき、可動枠２の垂れ下がり（片下がり）のおそれを少なくできる。
【００１０】
また、当接面部９４はローラ９９の外周面９９ａよりもやや下方に下げぎみに位置するよう形成されているので、当接面部９４が金属板１０の上面１１に接触した状態においてローラ９９の外周が金属板１０の上面１１に接触せず、可動枠２が閉じられた場合にローラ９９と金属板１０とが線接触しないので、ローラ９９と金属板１０の上面１１とが線接触することによる経時的な金属板１０の上面１１（受け面）の窪みを少なくできる。また、受け面を固定枠３の下枠３０の上面３１に取付けられた金属板１０により形成したので、可動枠２の重量を受ける受け面を簡単にかつ強固に形成できる。また、金属板１０の前縁にはローラ９９や当接面部９４を金属板１０の上面１１（受け面）上に案内する案内部１２を形成したので、金属板１０の上面１１にローラ９９や当接面部９４がスムーズに乗り上がるので、可動枠２を開閉する際に要する人力を軽減することができる。
【００１１】
尚、当接面部９４をローラ９９の外周面９９ａよりやや下方に位置するよう形成したが、当接面部９４とローラ９９の外周下面９９ａとを同じ高さの位置に形成してもよい。この場合でも、可動枠２が固定枠３に対して閉じられる場合において、可動枠の重量が当接面部９４とローラ９９とに分散して加わるので、ローラ９９と金属板１０の上面１１とが線接触することによる経時の金属板１０の上面１１（受け面）の窪みを少なくでき、可動枠２の垂れ下がり（片下がり）を少なくできる。また、受け面を形成した金属枠により固定枠３の下枠３０を形成してもよい。また、ローラ９９は金属製でも合成樹脂製でもよい。

[0008]
The slider device 9 will be described with reference to FIGS. The slider device 9 is attached to the back surface 20 of the lower end portion 21 near the free end side of the movable frame 2 and includes a main body 90 and a roller 99 as a rotating body. The main body 90 includes a storage portion 91 housed in a recess 22 formed on the back surface 20 of the lower end portion 21 of the movable frame 2, and a rear surface of the lower end portion 21 of the movable frame 2 extending in the same direction from both sides of the storage portion 91. Mounting portions 92 and 92 ′ that are attached to the back surface 20 so as to face 20, roller support members (rotary body support members) 93 and 93 ′ provided at the lower portion of the storage portion 91 and projecting to the back side of the movable frame 2, It is comprised with the contact surface part 94 provided in the lower part of base end part 93a, 93'a of roller support member 93,93 '. The roller 99 is rotatably attached via a rotation support shaft 96 mounted in shaft support holes 95 and 95 ′ formed in the tip end portions 93b and 93′b of the roller support members 93 and 93 ′. The metal plate 10 is attached over the lower frame 30 and the decorative plate 300 by a set screw 32 or the like on the lower frame 30 of the fixed frame 3 and the decorative plate 300, and the roller 99 is moved by opening and closing the movable frame 2. 10, the contact surface portion 94 contacts the upper surface 11 of the metal plate 10 when the movable frame 2 is closed with respect to the fixed frame 3, and the weight of the movable frame 2 is reduced. It is received by the upper surface 11 (receiving surface).
The contact surface portion 94 is formed such that at least the contact surface 94 c with the upper surface 11 of the metal plate 10 is positioned about 0.1 mm to 1.0 mm below the outer peripheral lower surface 99 a of the roller 99. With this configuration, when the movable frame 2 is fixed to the fixed frame 3, the movable frame 2 is planarly supported on the upper surface 11 of the metal plate 10 by the contact surface 94 c of the contact surface portion 94 of the slider device 9. .
The main body 90 is formed by bending a single metal plate 100 as shown in FIG. That is, since the contact surface portion 94 and the roller support members 93 and 93 ′ are formed by bending the single metal plate 100, the strength of the contact surface portion 94 and the roller support members 93 and 93 ′ can be improved.
Further, a guide portion 12 is formed on the front edge of the metal plate 10 by an arc surface, an inclined surface or the like for guiding the roller 99 and the contact surface portion 94 to the upper surface 11 of the metal plate 10.
The slider device 9 having the above configuration stores the storage portion 91 in the concave portion 22 formed on the back surface 20 of the lower end portion 21 of the movable frame 2 and through the mounting holes 92a formed in the mounting portions 92 and 92 ′. It is attached to the back surface 20 of the lower end portion 21 of the movable frame 2 with a set screw 23 or the like. Incidentally, the roller 99 is supported in both supported states by the roller support members 93 and 93 ′ on both sides via the rotation support shaft 96, and a retaining ring 97 is provided at the tip of the rotation support shaft 96 so that the rotation support shaft 96 is not detached. Installed. Further, the roller support member 93 is provided with a positioning hole 92b that engages with a positioning protrusion 24 formed on the back surface 20 of the lower end portion 21 of the movable frame 2, so that the main body 90 of the slider device 9 can be easily positioned on the movable frame 2. I have to.
[0009]
Next, the operation of the slider device 9 will be described. When closing the movable frame 2 to the fixed frame 3 side, first, the movable frame 2 is moved in the direction of the arrow B as shown in FIG. 5A, and the roller 99 is moved in the direction of the arrow C via the guide portion 12 along with the movement. It is guided by the upper surface 11 of the metal plate 10 while rotating. Then, as shown in FIG. 5B, the movable frame 2 further advances in the B direction while the roller 99 rolls on the upper surface 11 (receiving surface) of the metal plate 10 in the direction of the arrow C. The lower edge 94b slides on the guide portion 12 and slides on the metal plate 10, and the contact surface portion 94 completely rides on the upper surface 11 of the metal plate 10 as shown in FIG. The outer peripheral surface 99a of the roller 99 is separated from the upper surface 11 (receiving surface) of the metal plate 10, and the movable frame 2 is accommodated in the fixed frame 3 and closed. Accordingly, when the movable frame 2 is closed with respect to the fixed frame 3, the contact surface portion 94 rides with the contact surface 94 c contacting the upper surface 11 of the metal plate 10, and the outer peripheral surface 99 a of the roller 99 is made of metal. Since it is away from the upper surface 11 of the plate 10, the contact between the metal plate 10 and the slider device 9 becomes surface contact via the contact surface portion 94, and the weight of the movable frame 2 on which the game main body is mounted can be received and supported by the surface. Therefore, compared with the conventional structure in which the roller and the receiving surface are in line contact, the depression of the upper surface 11 (receiving surface) of the metal plate 10 with time can be reduced, and the movable frame 2 may be drooped (lowered). Less.
[0010]
Further, since the contact surface portion 94 is formed so as to be slightly below the outer peripheral surface 99 a of the roller 99, the outer periphery of the roller 99 is in a state where the contact surface portion 94 is in contact with the upper surface 11 of the metal plate 10. Is not in contact with the upper surface 11 of the metal plate 10, and the roller 99 and the metal plate 10 are not in line contact when the movable frame 2 is closed, so that the roller 99 and the upper surface 11 of the metal plate 10 are in line contact. The depression of the upper surface 11 (receiving surface) of the metal plate 10 over time can be reduced. Further, since the receiving surface is formed by the metal plate 10 attached to the upper surface 31 of the lower frame 30 of the fixed frame 3, the receiving surface that receives the weight of the movable frame 2 can be easily and firmly formed. Further, since the guide portion 12 for guiding the roller 99 and the contact surface portion 94 onto the upper surface 11 (receiving surface) of the metal plate 10 is formed on the front edge of the metal plate 10, the roller 99 or Since the contact surface portion 94 runs smoothly, it is possible to reduce the manpower required to open and close the movable frame 2.
[0011]
Although the contact surface portion 94 is formed to be positioned slightly below the outer peripheral surface 99a of the roller 99, the contact surface portion 94 and the outer peripheral lower surface 99a of the roller 99 may be formed at the same height. Even in this case, when the movable frame 2 is closed with respect to the fixed frame 3, the weight of the movable frame is dispersedly applied to the contact surface portion 94 and the roller 99, so that the roller 99 and the upper surface 11 of the metal plate 10 are connected. The depression of the upper surface 11 (receiving surface) of the metal plate 10 over time due to line contact can be reduced, and the sag (one-down) of the movable frame 2 can be reduced. Moreover, you may form the lower frame 30 of the fixed frame 3 with the metal frame in which the receiving surface was formed. The roller 99 may be made of metal or synthetic resin.
