Description

  The present invention relates to a pachinko machine.

  A normal pachinko machine has a guide rail installed on the game board for guiding a game ball driven by a launcher to the upper side of the game area, and a game ball that is strongly driven at the edge of the guide rail. A return member (return rubber) for rebounding is installed. Among the pachinko machines, there is a so-called “right-handed” type pachinko machine configured so that a privilege can be obtained by strongly hitting a game ball into the right side of the game area at a predetermined timing. Such right-handed pachinko machines have a plurality of obstacle nails arranged side by side at a position facing the return rubber, and by using these obstacle nails, the game balls bounced back by the return rubber are dropped downwards, The ball is configured not to flow down the left side of the game area.

  However, in a right-handed pachinko machine in which obstacle nails are installed side by side at a position facing such a return rubber, if used for a long time, the obstacle nail that receives the game ball bounced back by the return rubber is damaged. There was a case. Therefore, some right-handed pachinko machines are provided with a guide member for guiding the game ball bounced back by the return rubber in a predetermined direction, as in Patent Document 1.

JP-A-8-322988

  However, a pachinko machine with a guide member installed as described above requires a large space on the board surface for installing the guide member, and the flow direction of the game ball after colliding with the guide member is constant. Since it is easy, there exists a malfunction that the game content will be limited. There is also a problem that the guide member itself is damaged.

  The object of the present invention is to solve the problems of the conventional pachinko machine, and even if the game ball continues to collide with the return member for a long period of time, the obstacle nail or game member adjacent to the return member is damaged. In addition, it is difficult to provide a pachinko machine capable of making the game contents rich in variety without restricting the falling direction of the game ball after colliding with the return member.

Among the present inventions, the invention described in claim 1 is characterized in that a guide rail for guiding the game ball driven by the launching device to the upper side of the game area is installed in the game board, and The return member for rebounding is a pachinko machine installed at the front edge of the guide rail, and a decorative member is installed at the front edge of the guide rail, and the game is provided on the back surface of the decorative member. A locking pin is erected so as to be orthogonal to the board, and a pair of regulating walls are erected substantially in parallel so as to sandwich the locking pin, while the return member extends from the front surface to the back surface. A cylindrical locking hole penetrating into the locking hole , fitted between the pair of regulating walls and installed with the locking pin inserted through the locking hole, and the return member before the tip surface is adjacent the It is in a state orthogonal to the tangent line of the guide rail (i.e., the arc center which is formed by the return distal end surface and the guide rail member is adapted to position on substantially the same plane) be characterized by Is. In the present invention, the front end surface of the return member is perpendicular to the tangent line of the adjacent guide rail. The angle between the front end surface of the return member and the tangent line of the guide rail is within a range of about 90 ° ± 10 °. It means that there is.

The invention described in claim 2 is characterized in that in the invention described in claim 1 , a gap of a predetermined size is formed between the return member and at least one of the regulating walls. It is.

The invention described in claim 3 is the notch according to the invention described in claim 1 or 2 , wherein a columnar boss is erected on the back surface of the decorative member, and the return member is formed at the base end. Is installed in a state of being engaged with the columnar boss.

  In the pachinko machine according to claim 1, the tip surface of the return member is in a state orthogonal to the tangent of the guide rail (tangent of the portion adjacent to the tip surface of the return member), Since the game ball can be bounced back in the direction close to the incident direction when it hits the ball, the impact by the game ball can be reduced very effectively. Further, since the game ball bounces back in the direction close to the incident direction, the situation where the bounced game ball continues to hit the same obstacle nail or game member does not occur. Therefore, even when used over a long period of time, it is possible to effectively prevent obstacle nails and game members adjacent to the return member.

Further, in the pachinko machine according to claim 1 , since the return member is fitted between the inner restriction wall and the outer restriction wall provided upright on the decorative member, the game ball collides with the front end surface of the return member. In this case, the angle of the tip of the return member with respect to the incident direction of the game ball is limited to a certain range, and the game ball can be rebounded in a direction very close to the incident direction, so that the impact by the game ball is extremely effective. Can be reduced.

The pachinko machine according to claim 2 can absorb the deformation caused when the game ball collides with the front end surface of the return member by the gap between the return member and the regulating wall, and the front end surface of the return member is Since it can be slightly rotated around the locking pin, the impact caused by the game ball can be reduced extremely effectively.

The pachinko machine according to claim 3 , wherein the return member is installed in a state in which the notch of the base end is engaged with the columnar boss of the decorative member, and when the game ball collides with the distal end surface of the return member, The angle of the front end surface of the return member with respect to the incident direction of the game ball does not vary greatly, and the game ball continues to rebound in the same direction as the incident direction, so that the impact by the game ball can be reduced extremely effectively. In addition, the impact when the game ball collides with the tip end surface of the return member is also applied to the columnar boss, so that there is no situation where it is intensively applied to the locking pin, so damage to the locking pin is very effective. Can be prevented.

  Hereinafter, the pachinko machine of the present invention will be described in detail with reference to the drawings. FIG. 1 shows a pachinko machine according to the present invention.

It is provided to be slidable back and forth while maintaining the state. Further, a symbol start port 21 is provided below the center of the large game member 34, and an electric open / close winning device (so-called electric tulip) 22 is provided below the symbol start port 21. It has been. A gate 37 through which a game ball can pass is provided on the right side of the symbol starting port 21. In addition, in the game area 10, an electric lamp, a windmill, and the like are installed, and a number of obstacle nails 9, 9,.

  A corner decoration 24 as a decorative member is installed at a position adjacent to the tip (upper right portion) of the guide rail 8 to repel the game ball jumped to the right side along the guide rail 8. The return member 11 is installed using the corner decoration 24.

  2 shows an installation portion of the return member 11, and FIG. 3 shows a vertical cross section (AA line cross section in FIG. 2) of the installation portion of the return member 11. As shown in FIG. FIG. 4 shows a state of the back surface of the corner decoration 24. The return member 11 is integrally formed in a substantially rectangular parallelepiped shape with silicone rubber, and the front surface (front surface) and the back surface (rear surface) are parallel to each other. A columnar locking hole 12 is provided at substantially the center so as to penetrate from the front surface side to the back surface side, and the locking hole 12 has a front surface side closer to the back surface side than a substantial center. Compared to the larger diameter. In addition, the internal diameter of the large diameter part 16 and the small diameter part 17 is about 6.5 mm and about 4.5 mm, respectively. A semi-cylindrical notch 13 is provided at the proximal end of the return member 11, and a locking step 14 is provided on the inner side surface. On the other hand, a tapered surface 15 is provided at the front end of the outer side surface, and is in an acute angle with other portions.

  On the other hand, the corner decoration 24 is integrally formed of a synthetic resin in a vertically long shape. An inner regulating wall 26 and an outer regulating wall 27 are provided on both the left and right sides of the arcuate surface plate 25 so as to protrude rearward, and the cross section (cross section perpendicular to the longitudinal direction) is U-shaped. It has become. Further, the inner regulating wall 26 is curved so as to have a curvature radius substantially the same as that of the guide rail 8, and the outer regulating wall 27 faces the substantially parallel upper portion. Furthermore, a locking pin 28 for fixing the return member 11 protrudes from the upper surface of the back surface of the front plate 25. The locking pin 28 has a larger diameter on the proximal end side than on the substantially central side compared with the distal end side, and the diameters of the large diameter portion 31 and the small diameter portion 32 are about 6.0 mm and about 4 respectively. 0.0 mm. Two columnar bosses 29 and 30 for installing the corner decoration 24 on the game board 4 are arranged in a vertically projecting manner below the locking pin 28. Each of the columnar bosses 29 and 30 has a cross-shaped cross section, and has the same width and height. In addition, on the outside of the outer regulation wall 27, a contact plate 33 for allowing the corner decoration 24 to contact the game board 4 is provided.

  The return member 11 is fitted between the inner regulating wall 26 and the outer regulating wall 27, the step 14 is locked to the edge of the inner regulating wall 26, and the locking pin 28 is inserted into the locking hole 12. The corner decoration 24 is attached. When the barb member 11 is attached to the corner decoration 24 as described above, a gap (a gap of about 2.0 mm at the tip of the taper surface) is formed between the taper surface 15 of the barb member 11 and the inner regulation wall 26. Is done. The corner decoration 24 integrated with the return member 11 is inserted into the engagement holes (not shown) drilled in the game board 4 by inserting the columnar bosses 29 and 30 into the end of the guide rail 8. It is installed so that it is located below the edge. When the corner decoration 24 is thus installed on the game board 4, the tip surface of the return member 11 is in a state perpendicular to the tangent T at the edge of the guide rail 8 (that is, jumps along the guide rail 8. The incident angle of the coming game ball is substantially orthogonal) (see FIG. 2).

  On the other hand, on the lower side of the front frame 3, a supply tray 5 for supplying game balls to a launching device (not shown) and a storage tray 6 for storing game balls are provided vertically. On the right side of the storage tray 6, a launching handle 7 for operating the launching device projects.

  In the pachinko machine 1 configured as described above, when a game ball is launched from a launching device (not shown) by the turning operation of the launch handle 7, and the launched game ball wins the symbol start opening 21, A jackpot lottery is executed in a control device (not shown) installed in the interior, and if the jackpot lottery results in a “big jackpot”, a “hit state” occurs. Each time the game ball wins the symbol start opening 21, the winning symbol display device 19 displays the symbol variation display for a predetermined time, and displays the “hit symbol” or “out of symbol symbol” after the variation display. By doing so, the result of the jackpot lottery is displayed.

  In the “hit state”, the door member 36 of the special winning opening 35 is intermittently opened a predetermined number of times (sliding backward and immersing into the game board 4). Therefore, when a “hit” occurs, the player can win a lot of prize balls by winning a lot of game balls in the big prize opening 35.

  Also, when the “hit state” occurs after the predetermined “hit symbol” is displayed, after the “hit state” ends, the time for displaying the symbols on the winning symbol display device 19 is reduced by a predetermined number of times. "Time short state" occurs. In the “short time state”, every time a game ball passes through the gate 37, a winning lottery is executed in the internal control device, and the winning lottery in the winning lottery has a high probability, and the electric open / close winning device 22 is opened. . When a game ball wins the opened electric open / close winning device 22, the open / close door 23 slides backward to open the winning opening 20, and it is possible to win many game balls. Accordingly, when the “short-time state” occurs, the player can turn the launch handle 7 greatly to fire the game ball strongly (that is, “right-handed”) to win the right side prize. The mouth 20 can be awarded, and the game can be continued without greatly changing the number of game balls obtained by the occurrence of the “hit state”.

  When the player makes a so-called “right strike” in this way, the game ball that has been struck collides with the return member 11. At this time, the return member 11 has the game ball approximately in the incident direction. It bounces back in the same direction, reducing the impact of the game ball very effectively. Therefore, the situation that the obstacle nail 9,9 ... adjacent to the return member 11 is damaged does not occur.

  In the pachinko machine 1, as described above, the tip end surface (S in FIG. 3) of the return member 11 is in a state orthogonal to the tangent line T of the adjacent guide rail 8, and the game ball that has been driven into the return member 11 When a collision occurs, the game ball can be rebounded in a direction close to the incident direction, so that the impact caused by the game ball can be reduced very effectively. Further, since the game ball bounces back in the direction close to the incident direction, the situation where the bounced game ball continues to hit the same obstacle nail 9 or game member does not occur. Therefore, even when used over a long period of time, damage to the obstacle nails 9, 9,... Adjacent to the return member 11 and the gaming member can be effectively prevented.

  In the pachinko machine 1, the return member 11 is fitted between the inner restriction wall 26 and the outer restriction wall 27 erected on the corner decoration 24, so that the game ball collides with the front end surface of the return member 11. At this time, the angle of the front end surface of the return member 11 with respect to the incident direction of the game ball is limited within a certain range, and the game ball can be rebounded in a direction very close to the incident direction, so that the impact by the game ball is extremely effective. Can be reduced.

  Further, the pachinko machine 1 can absorb the deformation caused when the game ball collides with the front end surface of the return member 11 by the gap between the tapered surface 15 of the return member 11 and the outer regulating wall 27, and the return member 11. Since the front end surface of the ball can be slightly rotated around the locking pin 28, the impact caused by the game ball can be extremely effectively reduced.

  In addition, in the pachinko machine 1, the return member 11 is installed with the notch 13 at the base end engaged with the columnar boss 29 of the corner decoration 24, and the game ball collides with the front end surface of the return member 11. At this time, the angle of the front end surface of the return member 11 with respect to the incident direction of the game ball does not fluctuate greatly, and the game ball continues to rebound in the substantially same direction as the incident direction, so that the impact by the game ball can be reduced extremely effectively. it can. Further, since the impact when the game ball collides with the front end surface of the return member 11 is also applied to the columnar boss 29 and does not concentrate on the locking pin 28, the locking pin 28 is very damaged. Can be effectively prevented.

  The configuration of the pachinko machine of the present invention is not limited to the aspect of the above embodiment, and the machine frame, front frame, game board, supply tray, storage tray, launch handle, guide rail, return member, corner The configuration of the decoration (decoration member), game member, etc., such as the shape, structure, material, etc. can be changed as appropriate without departing from the spirit of the present invention.

  For example, the return member is not limited to one formed of silicone rubber as in the above embodiment, but can be changed to one formed of another elastic material such as synthetic rubber or natural rubber. In addition, when the return member is formed of synthetic rubber, acrylic rubber (ACM), acrylonitrile butadiene rubber (nitrile rubber NBR), isoprene rubber (IR), urethane rubber (U), ethylene propylene rubber ( EPM, EPDM), epiacrylhydrin rubber (CO, ECO), chloroprene rubber (CR), silicone rubber (Q), styrene butadiene rubber (SBR), butadiene rubber (BR), butyl rubber (IIR), fluorine rubber (FKM) Etc. can be used suitably. In addition, the return member can be formed of a composite material obtained by combining synthetic rubber, natural rubber, or the like with another elastic material.

  Further, the return member is not limited to the one installed on the game board using the corner decoration as in the above embodiment, and may be installed directly on the game board. Furthermore, the return member is not limited to the one installed using one locking pin as in the above embodiment, and may be installed using two or more locking pins. In addition, the return member is not limited to a rectangular parallelepiped shape as in the above embodiment, and is a rectangular parallelepiped shape as long as the tip surface is substantially orthogonal to the tangent of the guide rail (the tangent of the portion adjacent to the tip surface). It is also possible to change to those having other shapes.

  On the other hand, the corner decoration is not limited to the one installed on the game board by the two columnar bosses as in the above embodiment, but may be one installed on the game board using one or three or more columnar bosses. Further, the corner decoration is not limited to one in which one columnar boss is engaged with the proximal end of the return member as in the above embodiment, and two or more columnar bosses are engaged with the proximal end of the return member. It is also possible to change.

  In addition, the game board is not limited to the structure in which the game ball bounced back by the return member flows down in various directions as in the above-described embodiment, and the game member (perpendicular to the game board surface) is located near the return member. It is also possible to change to a configuration in which the flow direction of the rebounded game ball is constant. When such a configuration is adopted, there is an advantage that it becomes easy to design a right-handed type pachinko machine.

  In addition, in the pachinko machine of the present invention, the layout of game members, obstacle nails, etc. on the game board surface is not particularly limited. However, as in the above embodiment, the position is substantially perpendicular to the tip surface of the return member (inside the guide rail). It is desirable not to provide game members or obstacle nails in this part. By adopting such a configuration, it is possible to avoid a situation in which the game ball immediately after bouncing off at the tip surface of the return member continues to hit the same game member or obstacle nail, etc., thus preventing damage to the game member or obstacle nail to a higher degree. It becomes possible to do.
