Abstract

<P>PROBLEM TO BE SOLVED: To reduce the quantity of resin material to be used on a game board by fitting a game nail in two members: a front panel and a back panel. <P>SOLUTION: On the game board 1, the game nail 20 of the game machine is fitted and securely held in the two members: the front panel 31 and the back panel 32. Accordingly, the resin material can be reduced by the space between the front panel 31 and the back panel 32, and as a result, the quantity of use of the resin material on the whole and the weight of the game board 1 can be reduced. Lower holes 34 and 35 are formed on the front panel 31 and the back panel 32. As the lower holes 34 and 35 are dislocated in the vertical direction according to the difference in the vertical direction of the positions where the shaft of each game nail 20 crosses the front panel 31 and the back panel 32 respectively, an angle of elevation can be applied to the game nail 20 by fitting the game nail 20 into the lower holes 34 and 35. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention belongs to the technical field of ball game machines, and particularly relates to a game board mounted on a ball game machine.

The game board of the ball game machine is mainly made of plywood, but this may be made of synthetic resin. For example, JP-A-11-99244 (Patent Document 1) discloses a game board by injection molding. Japanese Laid-Open Patent Publication No. 10-179854 (Patent Document 2) discloses a game board made of a light-transmitting synthetic resin.
JP-A-11-99244 Japanese Patent Laid-Open No. 10-179854

  In order to complicate the course of the game ball on the game board, a metal (for example, brass) game nail (obstruction nail) is usually erected. For this reason, the game board is required to have a thickness sufficient to securely hold the game nail. Therefore, when the game board is made of synthetic resin, its weight is relatively large according to the plate thickness.

Further, an elevation angle of about 4 degrees is given instead of being perpendicular to the surface of the game board (the surface facing the player).
In the case of a game board made of veneer or beech plywood, there is no problem because it only needs to be struck upward by about 4 degrees.

  However, in the game board made of synthetic resin, if you try to drive the game nail like the one made of plywood, the game board will be cracked or cracked. In the meantime, a method of press-fitting a game nail into this prepared hole was taken.

The game board according to claim 1 is:
In the game board of the ball game machine,
The game board includes a synthetic resin front plate and a synthetic resin back plate arranged in parallel with a space between each other,
A game nail that penetrates through the front plate and reaches the back plate is fitted at an angle that is an elevation angle when the surface of the game board is along the vertical direction,
The front plate and the back plate are provided with pilot holes for fitting the game nails. The same one of the pilot holes for the game nails has the axis of the game nail as the front plate. And it is provided to be shifted in the vertical direction corresponding to the vertical difference of the position intersecting with the back plate.

  In this game board, the front plate made of synthetic resin and the rear plate made of synthetic resin are arranged in parallel with a space between each other, and the game nail is inserted through the front plate until reaching the back plate. It has been. The game nail is fitted to the two members of the front plate and the back plate, and is securely held. For this reason, since the synthetic resin material is not required for the space between the front plate and the back plate, the amount of resin material used can be reduced, and the weight of the game board can also be reduced.

  The front plate and the rear plate are provided with pilot holes for fitting game nails, but the same single pilot nail pilot hole intersects the front plate and the rear plate with the axis of the game nails. Since the position is shifted in the vertical direction corresponding to the vertical difference in position, the elevation angle can be given by fitting the game nail into the prepared hole. The “position where the axis of the game nail intersects with the front plate and the back plate” may correspond to each other such as the front surfaces of the front plate and the back plate, the back surfaces, or the center surfaces.

  The above-described vertical displacement of the pilot hole varies depending on the distance between the front plate and the back plate and the size of the elevation angle, but is actually less than 1 mm. Moreover, the plate | board thickness of a front plate and a back plate can be about 3-5 mm, respectively. If it is in this range, even if the pilot hole for the game nail is provided perpendicular to the surface of the front plate or the back plate, the rigidity of the game nail deforms the pilot hole, so there is no possibility that the game nail will bend. . That is, it is not necessary to incline the pilot hole according to the elevation angle (of course, it may be provided to be inclined).

  In the description about the elevation angle, “when the surface of the game board is along the vertical direction” is based on the position of the game board in a state where the game board is used (up and down relationship), and similarly “The same one hole for the game nail is displaced in the vertical direction corresponding to the vertical difference” is also the top and bottom in the state where the game board is used.

  In order to arrange the front plate and the rear plate in parallel, the peripheral member is arranged along the outer peripheries of the front plate and the rear plate and integrated with the front plate and the rear plate as described in claim 2. The distance between the front plate and the back plate is maintained by the peripheral member, and the front plate and the back plate are arranged in series via the peripheral member.

  The peripheral member may be provided in a wall shape over the entire circumference of the front plate and the back plate, or may be provided in a discrete manner. Further, in addition to the outer peripheral portion (that is, the portion from the center), ribs, bosses, and the like that maintain the above-mentioned distance may be arranged in cooperation with the peripheral member.

Next, embodiments of the present invention will be described based on examples of the present invention. The present invention is not limited to the following examples and the like, and it goes without saying that the present invention can be implemented in various ways without departing from the gist of the present invention.
[Example]
The game board 1 of the present embodiment is for a pachinko machine, and has a substantially rectangular shape as shown in FIG. The game board 1 is provided with guide rails 2a and 2b having a substantially arc shape by rail pins 21, and a substantially circular section surrounded by the guide rails 2a and 2b is a game area 4. In addition, the cut | interruption part between the front-end | tips of the guide rails 2a and 2b is closed with a return rubber (not shown).

  At the bottom of the game area 4, an out hole 5 is provided for discharging the game ball that has passed through the game area 4 as an out ball, and the guide rail 2 b guides the game ball to the out hole 5. Dent 2c is provided.

  Above the out hole 5, an attacker-type big winning opening 6 that is opened and closed by an opening and closing plate 6a is arranged. In addition, the normal winning openings 7 and 8 are arranged obliquely above and to the left and right of the special winning opening 6, respectively. The large winning port 6 and the normal winning ports 7 and 8 are assembled to a common base plate 9 to form a winning port unit 10 and are attached to the game board 1 with screws 11. In this embodiment, the winning opening unit 10 is adopted, but the large winning opening 6 and the normal winning openings 7 and 8 can be separately attached to the game board 1.

Above the grand prize winning port 6, a composite winning device 14 including an electric tulip type variable winning device 12 and a start winning port 13 is installed.
As is apparent from the drawing, when the variable winning device 12 is in the closed state (the illustrated state), the starting winning port 13 prevents the variable winning device 12 from being won (the variable winning device 12 is open when opened). Only winning a prize). The variable prize winning device 12 is released when a lottery occurs due to the game balls entering the passage openings 15 arranged on the left and right sides thereof.

  On the other hand, when the winning prize opening 13 is won, a jackpot lottery is performed, and in response to this, a display device (not shown in FIG. 1 is shown on the screen outline of the display device) arranged behind the game board 1. Corresponding fluoroscopic areas 16 are shown.) The symbols are displayed in a variable manner. If the jackpot lottery is won, the display device displays a jackpot following the symbol change display. When the jackpot display is made, the jackpot game is started and the jackpot 6 is opened. This display device is for effect display, and the result of the jackpot lottery is displayed by a 7-segment LED (not shown), but it is possible to determine whether or not it is a big hit only by display on the display device.

  Although the display device is not integrated with the game board 1 (not part of the game board 1), a guard rod 17 is attached to the game board 1 so as to correspond to the upper side of the transparent area 16, A stage 18 is attached so as to correspond to the lower side. In addition, wind turbines 19 are arranged on the left and right sides of the stage 18.

  The guard rod 17 prevents the game ball from above from entering the fluoroscopic region 16 (front of the screen of the display device) (the game ball is prevented from obstructing visibility through the front of the screen). For).

The guard rod 17 and the stage 18 also serve to show the player the upper and lower limits of the fluoroscopic region 16, that is, the screen of the display device, and the windmill 19 shows the left and right limits, though not exactly.
As illustrated, a large number of game nails 20 are implanted in the game area 4.

  A game nail 20 is arranged as a so-called ceiling nail in the upper center of the game area 4 (above the guard rod 17), and as a so-called life nail just above the normal winning openings 7, 8, the start winning opening 13 and the passing opening 15, respectively. Has been. In addition, below the left and right windmills 19 and the stage 18, row-like game nails 20 are arranged so as to guide the game balls to the composite winning device 14 or the passage port 15. In addition, although there is a difference in arrangement density, the game nails 20 are appropriately arranged. However, since the game nail 20 does not substantially exist in the transparent area 16 (in front of the screen of the display device), the game nail 20 does not impair the visibility of the screen.

  As shown in FIG. 2, the game board 1 has a two-layer structure of a front plate 31 and a back plate 32. A peripheral wall rib 33 (corresponding to a peripheral member) is connected to the outer peripheral portion of the back surface of the front plate 31. The peripheral wall rib 33 and the back plate 32 are bonded together with a transparent adhesive, so that they are integrated as illustrated. It has a structure.

  The front plate 31 (including the peripheral wall ribs 33) is made of a transparent synthetic resin (polycarbonate in the present embodiment), the thickness of the front plate 31 is 3 mm, and the rising height of the peripheral wall ribs 33 is 5 mm.

The back plate 32 is an injection molded product of a transparent synthetic resin (polycarbonate in this embodiment).
The above-described game area 4 is formed on the surface of the front plate 31, and the game nail 20 and the shaft nail of the windmill 19 (not shown because they are similar to the game nail 20) are hit against the front plate 31 and the back plate 32. ing. However, as shown, the game nail 20 and the shaft nail of the windmill 19 have an elevation angle, and this elevation angle is set to 4 degrees in this embodiment.

The guide rails 2a and 2b are also attached to the game board 1 by rail pins 21 that are driven against the front plate 31 and the back plate 32.
In FIG. 2, only one game nail 20 and one rail pin 21 are shown.

  As shown in detail in FIG. 3, the front plate 31 and the back plate 32 are provided with pilot holes 34 and 35, respectively. The game nail 20 and the shaft nail of the windmill 19 (hereinafter collectively referred to as the game nail 20 or the like). Are fitted in these pilot holes 34 and 35.

  As described above, the game nail 20 or the like has an elevation angle of 4 degrees, but the axes of the pilot holes 34 and 35 are not inclined with respect to the surfaces of the front plate 31 and the back plate 32, and It is provided vertically with respect to it.

  The elevation angle can be given to the game nail 20 and the like while using the pilot holes 34 and 35, as shown in FIG. 3A. This is because the position C of the game nail 20 is shifted in the vertical direction corresponding to the vertical difference between the positions where the axis C of the game nail 20 intersects the front plate 31 and the back plate 32 (see (d)). In the case of FIG. 3D, the angle at which the axis C intersects the surface of the front plate 31 and the surface of the back plate 32 is 4 degrees of the elevation angle.

  Then, the game nail 20 or the like has its tip aligned with the pilot hole 34 of the front plate 31 (FIG. 3A), and is inserted into the pilot hole 34 (FIG. 3B). When the tip reaches the pilot hole 35 of the back plate 32 (FIG. 3B), the cone-shaped tip enters the pilot hole 35 (FIG. 3C). Further, when the game nail 20 or the like is advanced and inserted for a set length, the tip of the game nail 20 or the like is fitted into the lower hole 35 of the back plate 32 and the middle is the lower hole 34 of the front plate 31. (Fig. 3 (d)). Thus, the elevation angle of 4 degrees is given to the game nail 20 or the like by the vertical displacement of the pilot holes 34 and 35. Since the elevation angle is given by the vertical displacement of the lower holes 34, 35, stress is generated between the lower holes 34, 35 and the game nail 20 or the like. Since the 31 and the back plate 32 are made of synthetic resin, this force causes the pilot holes 34 and 35 to be deformed (elastic deformation or plastic deformation). That is, the game nail 20 or the like does not bend according to the displacement of the pilot holes 34 and 35, and its axis C maintains a straight line.

  As described above, the game board 1 according to the present embodiment includes the front plate 31 made of synthetic resin and the rear plate 32 made of synthetic resin arranged in parallel with a space between each other. A game nail 20 that penetrates through the front plate 31 and reaches the back plate 32 is fitted at an angle that becomes an elevation angle along the vertical direction, and the game nail 20 is fitted into the front plate 31 and the back plate 32. Although the pilot holes 34 and 35 for wearing are provided, the same one of the pilot holes 34 and 35 for the game nail 20 is a position where the axis C of the game nail 20 intersects the front plate 31 and the back plate 32. Are provided so as to be shifted in the vertical direction corresponding to the vertical difference between the two.

  In this game board 1, the game nail 20 is fitted into the two members of the front plate 31 and the back plate 32 and is securely held. For this reason, since the synthetic resin material is not needed for the space between the front plate 31 and the back plate 32, the amount of the resin material used can be reduced, and the weight of the game board 1 can also be reduced.

  Since peripheral wall ribs 33 (peripheral members) are connected to the outer periphery of the back surface of the front plate 31 and the peripheral wall ribs 33 and the back plate 32 are bonded with a transparent adhesive, the front plate 31 and the back plate 32 are connected. The parallel relationship (the distance between the front plate 31 and the back plate 32) can be reliably maintained.

  The front plate 31 and the back plate 32 are provided with pilot holes 34 and 35 for fitting the game nails 20. The same one of the pilot holes 34 and 35 for the game nails 20 is provided in the game nails 20. Since the vertical axis is provided so as to be shifted in the vertical direction corresponding to the vertical difference between the positions of the front plate 31 and the back plate 32, the elevation angle (the embodiment) can be obtained by fitting the game nail 20 into the lower holes 34, 35. Then 4 degrees) can be given.

  The vertical displacement of the pilot holes 34 and 35 varies depending on the distance between the front plate 31 and the back plate 32 and the size of the elevation angle, but is actually slight. Further, the thickness of the front plate 31 and the back plate 32 can be set to about 3 to 5 mm, respectively. Within this range, even if the pilot hole for the game nail 20 is provided perpendicular to the surface of the front plate 31 or the back plate 32, the rigidity of the game nail 20 deforms the pilot hole. There is no risk of turning. That is, it is not necessary to incline the pilot holes 34 and 35 according to the elevation angle.
