Description

  The present invention relates to a ball game machine such as a pachinko machine.

  2. Description of the Related Art Conventionally, a ball game machine such as a pachinko machine includes a launch rail that launches a game ball and a guide rail that guides the game ball launched from the launch rail to the upper side of the game board. A ball return path is provided on the lower side between the guide rail and the firing rail to return the game ball stalled in the middle of the guide rail to the lower plate side. ing.

  And when launching the game ball, after hitting the game ball on the launch rail with a striking rod, and passing it over the ball return passage from the launch rail to the lower side of the guide rail by its inertial force The game ball that is guided along the guide rail to the upper side of the game board and stalled in the middle of the guide rail returns downward along the guide rail, and passes between the guide rail and the launch rail through the ball return passage. It is designed to return to the bottom plate side.

  In a conventional ball game machine, a ball return passage is provided below the firing rail and the guide rail, and the game ball stalled in the middle of the guide rail is guided back to the ball return passage from the lower end side of the guide rail. Therefore, in order to ensure the transfer of the game ball from the launch rail to the guide rail, and to ensure that the stalled game ball is guided to the ball return path, a large interval in the longitudinal direction of the launch rail is required. It is necessary to ensure that the lower side of the guide rail is gently curved and to be placed on the lower side from the extension line of the firing rail.

  However, if the lower side of the guide rail is placed on the lower side of the extension line of the launch rail, the game ball launched from the launch rail jumps over the ball return passage with inertial force and passes over the ball return passage to guide. When the lower end side of the rail is contacted, a very large impact is received from the guide rail. For this reason, when the game ball is transferred from the launch rail to the guide rail side, there is a drawback that the inertia force of the game ball is greatly reduced by the impact, and a miss of launching the game ball that stalls in the middle of the guide rail is likely to occur.

In view of such a conventional problem, the present invention is configured so that a game ball stalled in the middle of a guide rail is returned from the upper side of the guide rail to reduce an impact when the game ball is transferred to the guide rail. In addition to reducing the stall of the game ball along the way, the game ball can be guided along the guide rail to the upper side of the game board in a stable state, and even if the game ball stalls in the middle of the guide rail, An object of the present invention is to provide a bullet ball game machine that can smoothly and surely return the game ball to the dish side.

The present invention is provided with a launching device 9 for launching a game ball on the launch rail 18 to the game board 5 side below the game board 5, and an inner surface surrounding a plurality of winning holes in the front of the game board 5.

  In the mounting member 25, the bracket part 30 is attached to the game board 5 with screws 31 in a state where the ball guiding part 28 is made to correspond to the ball return port 23 of the game board 5. Note that the lower end of the tip of the support portion 27 is cut so as to be thin so that a game ball moving on the guide rail 11 does not come into contact therewith.

  The guide member 24 includes a columnar mounting portion 32, and a strip-shaped guide portion 33 that protrudes horizontally from the mounting portion 32 to the upper surface side of the guide rail 11, and is a flexible soft material having wear resistance. It is integrally formed of a synthetic resin material. A thin plate-like bent portion 34 is formed on the right end side of the guide portion 33, and a plurality of scooping pieces 35 formed in a strip shape by slits are formed on the left end side. The tip of each scooping piece 35 is cut so that the lower side is slanted so that the game ball that has stalled in the middle of the guide rail 11 and returned to the guide member 24 side is smoothly transferred from the tip to the guide portion 33. To move to.

  In this guide member 24, the attachment portion 32 is detachably attached to the attachment portion 26 of the attachment member 25 from the front side in a fitting manner, and the left and right sides of the bending portion 34 are supported by the support portion 27 and are held substantially horizontally. In addition, the tip of the scooping piece 35 is placed on the guide rail 11.

  A ball return prevention member 36 that prevents the game ball from returning to the passage 12 is provided at the tip of the inner rail 13. As shown in FIG. 7, the ball return preventing member 36 includes a main body portion 37 that engages with the front end portion of the inner rail 13, and a protrusion 38 that is bent from the front end of the main body portion 37 toward the guide rail 11. And a bracket portion 39 provided on the game board 5 side of the main body portion 37.

  The ball return prevention member 36 is configured to fix the bracket portion 39 to the game board 5 with screws 40 so that the distance k between the tip of the projection 38 and the guide rail 11 is slightly larger than the diameter of the game ball. ing. As shown in FIG. 3, a fall prevention member 41 is mounted on the back side of the front plate 4 so that the game ball does not fall from the lower end portion of the guide rail 11 and the launch rail 18 to the front plate 4 side.

  Next, the operation of the pachinko machine having the above configuration will be described. At the start of the game, when a game ball is placed in the upper plate 6 and the operation handle 10 is turned, the launching device 9 is activated, and one game ball is supplied from the upper plate 6 onto the launch rail 18 one by one. Fire along the firing rail 18 by hitting the spear 19.

  The game ball hit by the hitting ball 19 usually reaches the upper side of the game board 5 via the launch rail 18 and the guide rail 11, and then falls downward along the game board 5 while hitting the obstacle nail, Enter the winning entrance 14 or the like, or enter the lower outport. Further, when the game ball moves from the launch rail 18 to the guide rail 11, the tip end side of the launch rail 18 and the lower end side of the guide rail 11 are arranged adjacent to each other. Is immediately supported by the guide rail 11. Therefore, when the game ball contacts the guide rail 11, it moves smoothly with almost no impact.

  When the game ball after launch moves upward along the guide rail 11 and comes into contact with the lower side of the guide member 24, the flexible portion 34 bends so that the free end side of the guide member 24 is lifted, and the guide member A game ball passes to the upper side of 24. If the game ball passes above the guide member 24, the free end side of the guide member 24 descends due to the elastic return of the flexure 34 and contacts the upper surface of the guide rail 11.

  If the game ball further rises and moves to the upper end of the passage 12, the game ball passes between the ball return prevention member 36 along the guide rail 11 without contacting the ball return prevention member 36. For this reason, on the upper end side of the passage 12, the game ball is smoothly guided without receiving resistance.

  The game ball flies from the upper end of the guide rail 11 to the upper side of the game board 5 and hits an obstacle nail or the like. At this time, even if the game ball hitting the obstacle nail or the like may bounce back toward the passage 12, the ball return prevention member 36 is disposed inside the guide rail 11 with a gap k slightly larger than the diameter of the game ball. Therefore, there is almost no possibility that the game ball returns from the space between the guide rail 11 and the ball return prevention member 36 to the passage 12 side.

  Also, if the game ball that has passed above the guide member 24 stalls in the middle of the guide rail 11 due to insufficient striking force, etc., it will return downward along the guide rail 11 and from the guide rail 11 to the free end side of the guide member 24 After passing through the upper surface of the guide portion 33, it is guided to the front side of the ball return port 23. Then, the game ball is guided to the ball return port 23 by the ball guide portion 28 of the mounting member 25 and returns to the lower plate 8 side.

  According to the configuration of this embodiment, the ball return port 23 for returning the game ball to the lower plate 8 side, and the guide member 24 for guiding the game ball stalled in the middle of the guide rail 11 to the ball return port 23 side, are guided. It is provided on the upper side of the rail 11 and at the lower part of the game board 5, and is returned from the upper side of the guide rail 11 to the lower plate 8 side through the guide member 24 and the ball return port 23. It is not necessary to leave a large gap between the lower end side of the guide rail 11 so that the lower end side of the guide rail 11 is below the extension line of the firing rail 18.

  Accordingly, it is possible to adopt a configuration in which the lower end side of the guide rail 11 is disposed adjacent to the firing rail 18 so that the lower end side of the guide member 24 and the guide rail 11 substantially coincides with the extension line of the firing rail 18. Yes, it is possible to reduce the impact of game balls launched from the launch rail 18 when moving from the launch rail 18 to the lower end side of the guide rail 11, and to reduce the stall of the game ball in the middle of the guide rail 11, and to be stable In this state, the game ball can be guided to the upper side of the game board 5.

  In particular, by arranging the lower end side of the guide rail 11 adjacent to the firing rail 18 so that the lower end sides of the guide member 24 and the guide rail 11 substantially coincide with the extension line of the firing rail 18, the guide rail 24 and the guide rail 11 are guided. The game ball can be moved to the 11 side very smoothly, and the length of the launch rail 18 can be lengthened, or a straight portion can be provided on the lower end side of the guide rail 11, so that the game ball in a stable state Can be guided.

  For this reason, the game ball can be smoothly and reliably launched from the launch rail 18 through the guide rail 11 to the upper side of the game board 5, and the inertial force of the game ball in the middle of the launch rail 18 and the guide rail 11 is reduced. Since the game ball can be guided to the upper side of the game board 5 with as little as possible reduction, the flight distance of the game ball flying from the upper end of the guide rail 11 to the upper side of the game board 5 and the variation of the flight trajectory Less.

  Even if the game ball stalls in the middle of the guide rail 11, the game ball is guided from the guide rail 11 to the ball return port 23 via the guide member 24, and the lower plate 8 Therefore, it is possible to prevent the game balls from being clogged with the guide rail 11 or the firing rail 18.

  One end side of the guide member 24 is mounted on the game board 5 side, and the free end side of the other end is placed on the upper surface of the guide rail 11, and the free end side swings in the vertical direction. Since the bent portion 34 is provided in the middle, the structure of the guide member 24 is very simple, but when the game ball passes the guide member 24, the bent portion 34 A game ball can be passed to the upper side of the guide member 24 without reducing the inertial force of the ball, and when the game ball stalls in the middle of the guide rail 11 after the passage, the game ball is moved to the guide member 24. It is possible to reliably scoop from the guide rail 11 side on the free end side and guide it to the ball return port 23 side.

  Further, the guide member 24 has a bent portion 34 in the middle, and the other end of the guide member 24 is divided into a plurality of scooping pieces 35 by slits. The end side is easily bent, and the inertial force of the game ball due to the frictional resistance of the guide member 24 can be suppressed as much as possible, thereby preventing the game ball from stalling.

  In addition, when the guide member 24 is damaged or deformed, the guide member 24 is detachably attached to the mounting member 25, so it is only necessary to remove the guide member 24 and replace it with a new one quickly and easily. It can correspond to. Further, since the mounting member 25 is provided with a ball guiding portion 28 for guiding the game ball guided by the guide member 24 to the ball return port 23, the game ball guided to the front side of the ball return port 23 by the guide member 24 is provided. The ball guiding unit 28 can reliably guide the ball to the ball return port 23.

  Since the ball return prevention member 36 is disposed at the front end of the passage 12 inside the guide rail 11 with a gap k slightly larger than the diameter of the game ball, the game ball is separated from the guide rail 11 and the ball return prevention member 36. Can pass along the guide rail 11 without contacting the ball return preventing member 36. For this reason, on the lower side of the guide rail 11, there is no resistance on the upper side even if a slight frictional resistance occurs when the game ball lifts the free end side of the guide member 24. While preventing the ball from returning, it is possible to smoothly guide the game ball along the guide rail 11 while suppressing the stall of the game ball as much as possible.

  8 and 9 show a second embodiment of the present invention, in which a guide member 24 is pivotally attached to a mounting member 25 so as to be rotatable and detachable. The guide member 24 has a mounting hole 42 on the base side, and is pivotably mounted in a vertically swingable and removable manner by a pivot shaft 43 in the front-rear direction inserted into the mounting hole 42. The pivot shaft 43 has a split shape protruding forward from the mounting member 25 and is integrally formed with the mounting member 25. A stopper 44 is formed at the tip of the pivot shaft 43. In the case of the present embodiment, it can be carried out similarly to the first embodiment.

  10 and 11 show a third embodiment of the present invention, which is provided with a drive means 45 for lifting the free end side of the guide member 24 in conjunction with the launch of a game ball. A solenoid is used for the driving means 45, and is arranged vertically on the back side of the game board 5 below the ball return port. A coil spring 47 for urging the operating rod 46 downward is attached to the operating rod 46 of the driving means 45, and an interlocking member 48 for lifting the free end side of the guide member 24 is screwed to the upper end portion. It is fixed by.

  The interlocking member 48 is formed by bending a metal wire, and includes a lower horizontal part 49 extending forward, a vertical part 50 extending upward from the front end of the lower horizontal part 49, and an upper part extending forward from the upper end of the vertical part 50. The lower horizontal portion 49 is inserted into the cutout groove 52 of the game board 5, and the upper horizontal portion 51 protrudes from the center lower side of the guide member 24.

  In this embodiment, when the game ball hit by the hitting rod 19 reaches the lower side of the guide member 24, the drive means 45 is excited and the operating rod 46 is raised, and the guide member 24 is moved via the interlocking member 48. The driving means 45 is interlocked with the launching device 9 so as to lift the free end side. For this reason, it is not necessary to lift the free end side of the guide member 24 with the game ball as in the first embodiment, and the resistance of the guide member 24 to the game ball can be completely eliminated.

  When the game ball passes below the guide member 24, the excitation of the driving means 45 is released, the operating rod 46 is lowered by the coil spring 47, and the free end side of the guide member 24 is restored by the elastic return of the flexible portion 34. Place on the guide rail 11. Even if the driving means 45 does not operate or there is a deviation in the timing to raise the guide member 24, as in the first embodiment, if the game ball comes into contact with the lower side of the guide member 24, Since the free end side is lifted, the game ball can pass above the guide member 24.

  Each embodiment includes the following inventions. The first is a ball guide machine provided with a launch rail 18 for launching a game ball and a guide rail 11 for guiding the game ball launched from the launch rail 18 to the upper side of the game board 5.
