【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、可動枠の下端部に回転体支持部材を設け、この回転体支持部材には、可動枠の開閉に伴い固定枠の下部に形成された受け面上を回転する回転体と、可動枠が固定枠に対して閉じられた場合に受け面上に接触する当接面部とを設けたので、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。また、当接面部の下面を回転体の外周下面より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、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、一枚の金属板材が折曲されて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、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。

[Problems to be solved by the invention]
However, in the gaming machine frame of the above-mentioned patent document, since the roller in the slider device is configured to be in contact with and supported on the receiving surface at the outer periphery thereof, the game board, the ball storage tank, the ball and the ball are closed when the movable frame is closed. The weight (about 20 kg) of the movable frame on which the game main body including the gutter, the control device, the power supply device, and the like is mounted is added to the receiving surface via the roller. There has been a problem that the receiving surface that comes into line contact gradually becomes concave, which causes the movable frame to hang down. In particular, in the case of Patent Document 3, the movable frame is raised with the roller as a fulcrum, and the problem that the movable frame hangs down due to the structure in which the weight of the movable frame is easily added to the receiving surface via the roller is remarkable. Occurs.
SUMMARY OF THE INVENTION An object of the present invention is to provide a gaming machine frame having a structure capable of reducing hanging of a movable frame, that is, one-sided movement of a movable frame.
[0005]
[Means for Solving the Problems]
The present invention provides a game machine frame including a fixed frame, and a movable frame mounted on the fixed frame so as to be openable and closable, and on which a game main body is mounted, wherein a rotating body support member is provided at a lower end portion of the movable frame. The rotating body support member includes a rotating body that rotates on a receiving surface formed below the fixed frame as the movable frame is opened and closed, and comes into contact with the receiving surface when the movable frame is closed with respect to the fixed frame. Since the contact surface is provided, the weight of the movable frame on which the game main body is mounted can be received on the surface of the receiving surface via the contact surface, so that the depression of the receiving surface over time can be reduced, and the movable frame sags. (Side drop) can be reduced. Further, by providing the lower surface of the contact surface portion below the outer peripheral lower surface of the rotating body, the outer periphery of the rotating body does not contact the receiving surface when the contact surface portion is in contact with the receiving surface, and the movable frame is closed. In this case, there is no line contact between the rotating body and the receiving surface, so that it is possible to reduce the possibility of occurrence of dents in the receiving surface over time due to linear contact between the rotating body and the receiving surface.
Further, since the receiving surface is formed by the metal plate attached to the upper surface of the lower frame of the fixed frame, the receiving surface for receiving the weight of the movable frame can be formed easily and firmly.
In addition, since one metal plate is bent to form the contact surface portion and the rotating body support member, the strength of the contact surface portion and the rotating body support member can be improved.
In addition, since the guide portion for guiding the rotating body or the contact surface portion on the receiving surface is formed at the front edge of the receiving surface, the rotating body and the contact surface portion are smoothly placed on the receiving surface via the guide portion. As a result, the manpower required to open and close the movable frame can be reduced.
[0006]
BEST MODE FOR CARRYING OUT THE INVENTION
A gaming machine frame 1 according to an embodiment of the present invention will be described with reference to the drawings. 1 is a perspective view showing the gaming machine frame 1 with the movable frame 2 opened, FIG. 2 is a perspective view showing the appearance of the slider device 9, FIG. 3 is an exploded perspective view of the slider device 9, and FIG. FIG. 5 is an explanatory view of the operation of the slider device 9.
[0007]
FIG. 1 shows the movable frame 2 of the gaming machine frame 1 opened from the fixed frame 3 so as to show the back surface 2 ′ thereof. As shown in FIG. 1, a gaming machine frame 1 has a movable frame 2 on which a game main body composed of a game board, a ball storage tank, a ball gutter, a control device, a power supply device, and the like, which are not shown, is mounted. As shown by arrows A and B, the frame-shaped fixing frame 3 is attached to the frame-shaped fixing frame 3 to be attached so as to be openable in the front lateral direction as shown by arrows A and B. A transparent panel (not shown) facing the game area of the game board is attached to the front surface of the movable frame 2 so as to be openable and closable, and a front decoration (not shown) is attached. The fixed frame 3 includes an upper frame 29, a lower frame 30, a right horizontal frame 33 connecting the upper frame 29 and the lower frame 30 at both ends, and a left horizontal frame (not shown). Further, a decorative plate 300 is attached to the front side of the lower frame 30 of the fixed frame 3. The movable frame 2 and the fixed frame 3 are formed by wooden frames. A locking device 5 is arranged on a vertical edge on the free end side of the movable frame 2. The locking device 5 and the movable frame lock mechanism 6 are attached to a rear plate 8 fixed to the back surface 2 ′ of the movable frame 2. The rear plate 8 and the movable frame 2 form a space for accommodating a game board of a pachinko machine or a turning display of a slot machine using pachinko balls as a game medium. When the movable frame 2 is rotated in the direction of arrow B and is attached to the fixed frame 3, a key (not shown) is manually inserted into the locking device 5 from the front side of the movable frame 2 in one direction. For example, when rotated 90 degrees, the movable frame lock lever 6 a of the movable frame lock mechanism 6 provided on the back surface 20 of the movable frame 2 comes off the movable frame stopper 7 provided on the fixed frame 3. Thereby, the movable frame 2 can be opened and closed with respect to the fixed frame 3 in the arrow AB direction. With the movable frame lock lever 6a being disengaged from the movable frame stopper 7, the movable frame 2 is pulled to the front by manual operation, so that the movable frame 2 is opened to the front in the horizontal direction indicated by arrow A around the frame hinges 4 and 4 '. Is done. Further, when the movable frame 2 is manually pushed toward the back side indicated by the arrow B from the state where the movable frame 2 is opened, the tip hook of the movable frame lock lever 6a moves beyond the movable frame stopper 7 and is movable. The frame lock lever 6a returns to the original position by the spring force built into the movable frame lock mechanism 6, and engages with the movable frame stopper 7. As a result, the movable frame 2 cannot be opened and closed with respect to the fixed frame 3.
[0008]
The slider device 9 will be described with reference to FIGS. The slider device 9 is mounted near the free end of the movable frame 2 and on the back surface 20 of the lower end portion 21 and includes a main body 90 and a roller 99 as a rotating body. The main body 90 includes a storage portion 91 that is stored in a concave portion 22 formed on the back surface 20 of the lower end portion 21 of the movable frame 2, and a back surface of the lower end portion 21 of the movable frame 2 that extends in the same direction from both sides of the storage portion 91. Mounting portions 92, 92 ′ attached to the back surface 20 so as to face the rear surface 20, roller support members (rotary body support members) 93, 93 ′ provided at the lower portion of the storage portion 91 and protruding to the back side of the movable frame 2; The roller support members 93 and 93 'are configured by a contact surface portion 94 provided below the base end portions 93a and 93'a. The roller 99 is rotatably mounted via a rotary support shaft 96 mounted in shaft support holes 95, 95 'formed in the distal end portions 93b, 93'b of the roller support members 93, 93'. The metal plate 10 is attached to the lower frame 30 and the upper surface 31 of the decorative plate 300 over the lower frame 30 and the decorative plate 300 by a set screw 32 or the like. When the movable frame 2 is closed with respect to the fixed frame 3, the contact surface portion 94 comes into contact with the upper surface 11 of the metal plate 10 to reduce the weight of the movable frame 2. It is to be received on the upper surface 11 (receiving surface).
The contact surface portion 94 is formed such that at least the contact surface 94c 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 99a of the roller 99. With this configuration, when the movable frame 2 is fixed to the fixed frame 3, the contact surface 94 c of the contact surface portion 94 of the slider device 9 supports the movable frame 2 on the upper surface 11 of the metal plate 10 in a planar manner. .
The main body 90 is formed by bending a single metal plate material 100 as shown in FIG. That is, since one metal plate member 100 is bent to form the contact surface portion 94 and the roller support members 93 and 93 ', the strength of the contact surface portion 94 and the roller support members 93 and 93' can be improved.
A guide portion 12 is formed at the front edge of the metal plate 10 by an arc surface, a slope, or the like for guiding the roller 99 and the contact surface portion 94 to the upper surface 11 of the metal plate 10.
In the slider device 9 having the above-described configuration, the storage portion 91 is stored in the concave portion 22 formed on the back surface 20 of the lower end portion 21 of the movable frame 2, and is mounted via the mounting holes 92 a formed in the mounting portions 92 and 92 ′. The movable frame 2 is attached to the back surface 20 of the lower end portion 21 with a set screw 23 or the like. The roller 99 is supported by both roller supporting members 93 and 93 ′ via a rotation support shaft 96 in a bi-support state, and a retaining ring 97 is provided at the tip of the rotation support shaft 96 so that the rotation support shaft 96 does not come off. Installed. The roller support member 93 is provided with a positioning hole 92b that engages with the positioning protrusion 24 formed on the back surface 20 of the lower end portion 21 of the movable frame 2 to facilitate positioning of the main body 90 of the slider device 9 on the movable frame 2. I have to.
[0009]
Next, the operation of the slider device 9 will be described. When the movable frame 2 is closed to the fixed frame 3 side, first, the movable frame 2 is moved in the direction of arrow B as shown in FIG. 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 direction B while the roller 99 is rolling on the upper surface 11 (receiving surface) of the metal plate 10 in the direction of arrow C, and the rear end 94a of the contact surface portion 94 is formed. The lower edge 94b slides on the metal plate 10 while sliding on the guide portion 12, 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 housed in the fixed frame 3 and closed. Therefore, when the movable frame 2 is closed with respect to the fixed frame 3, the contact surface portion 94 comes in contact with the contact surface 94 c against the upper surface 11 of the metal plate 10, and the outer peripheral surface 99 a of the roller 99 is Being separated from the upper surface 11 of the plate 10, the contact between the metal plate 10 and the slider device 9 becomes a 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 with each other, the depression of the upper surface 11 (receiving surface) of the metal plate 10 with the passage of time can be reduced, and the danger of the movable frame 2 sagging (side-down) can be reduced. Can be reduced.
[0010]
Further, since the contact surface portion 94 is formed so as to be slightly lower than the outer peripheral surface 99 a of the roller 99, the outer peripheral surface 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. Does not come into contact with the upper surface 11 of the metal plate 10 and the roller 99 does not make line contact with the metal plate 10 when the movable frame 2 is closed. 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 for receiving the weight of the movable frame 2 can be formed easily and firmly. Further, since the guide portion 12 for guiding the roller 99 and the contact surface portion 94 on the upper surface 11 (receiving surface) of the metal plate 10 is formed at the front edge of the metal plate 10, the roller 99 and the roller 99 are provided on the upper surface 11 of the metal plate 10. Since the contact surface portion 94 rides smoothly, it is possible to reduce the manpower required for opening and closing the movable frame 2.
[0011]
Although the contact surface portion 94 is formed to be 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. Also in this case, when the movable frame 2 is closed with respect to the fixed frame 3, the weight of the movable frame is distributed and added 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 separated from each other.
