Description

  The present invention relates to a pachinko machine in which a windmill made of synthetic resin is attached to a game board as a windmill for changing the flow path of pachinko balls.

  Conventionally, various proposals in consideration of decorativeness have been made in windmills of pachinko machines (for example, Patent Documents 1 to 3).

  In Patent Document 1, a shaft cylinder for inserting a nail is integrally formed of a translucent material at the center of the back surface of the disk portion, and a plurality of blade members are centered around the shaft center on the outer periphery of the shaft cylinder. It is arranged radially at equiangular intervals, and its disc part is covered with a tin decorative plate, which is a non-transparent decorative plate with a pattern or the like, and is drilled in three places on the front of this decorative plate. It has been proposed to enhance the decorativeness by illuminating a windmill provided so that a part of the disk portion can be seen through the provided annular hole with a light emitting diode embedded behind the windmill (FIG. 10A). reference).

  Patent Document 2 discloses a windmill body having a peripheral wall on the front circumferential surface, a size substantially the same as a concave portion surrounded by the peripheral wall, a decorative sheet having an arbitrary design, the same size as the concave portion, A transparent or translucent front decorative plate that can be locked by means, and a decorative sheet is interposed in the recess of the windmill body so that the front decorative plate can be engaged and disengaged by the locking means. A wind turbine that appropriately responds to changes in the design is proposed (see FIG. 10B).

Patent Document 3 uses a windmill in which at least a part is formed of a light-transmitting member in a portion where the game board overlaps when viewed from the player, so that the player can visually recognize the back side of the windmill. (See FIG. 10C).
JP 2002-153614 A (FIGS. 1 and 2) JP-A-10-234944 (FIGS. 3 and 4) Japanese Patent Laying-Open No. 2005-287785 (FIGS. 3 and 5)

  Since the windmill described in Patent Document 1 is synthetic resin integral molding, the shaft holes through which the nails are inserted have the same diameter. For this reason, if the diameter of the shaft hole is increased in order to facilitate rotation, rattling increases, and smooth rotation may not be possible.

  The windmills described in Patent Documents 2 and 3 are structured so as to lock a separate front decorative plate, so that both ends of the shaft hole can be made thin and the middle part can be made thick, so that the windmill rotates smoothly without rattling. It is possible to construct a windmill that performs.

  However, in the windmill described in Patent Document 2, since the front decorative plate is locked in the recess surrounded by the peripheral wall of the windmill body, some parts are used after being assembled once. It is difficult.

  Further, the windmill described in Patent Document 3 includes three parts, a disk member 311, a blade member 313, and a connecting member 312, as shown in <FIG. 5 of JP-A-2005-287785> in FIG. Since it is what is assembled by aligning, the alignment at the time of an assembly is troublesome. Further, the engaging piece 313 c provided on the blade member 313 is fitted into the hole 312 c provided on the connecting member 312 from the rear, so that the connecting member 312 and the blade member 313 are coupled to the connecting member 312 at the same time. Since the deployed locking piece 312b is locked at the inner peripheral edge of the opening 311c via the opening 311c, the connecting member 312 and the disk member 311 are coupled to each other. Therefore, it is not easy to disassemble.

  The purpose of this application is to make it possible to visually recognize how the pachinko ball changes its flow path by a windmill that rotates smoothly, and to prevent the decorative effect of adopting a light-transmitting synthetic resin from the game board. .

The pachinko machine of the present invention, which has been made to achieve the above object, has a windmill for changing the flow path of the pachinko ball on the surface of the game board with nails and fixed with nails and adopts the following configuration. It is characterized by that.

In addition, each latching claw 15 with a return is arrange | positioned in the position where the angle between a blade | wing and a latching claw becomes 60 degree | times so that it may each be located in the middle of the blade | wing 12-12. These three locking claws 15 with a bar shape have a single arrow shape with the barb 16 facing outward. Each of the locking claws 15, 15, 15 with barbs includes a root portion 15 a extending outward from the upper end of the shaft tube portion 11, a main body portion 15 b extending in the axial direction from the tip of the root portion 15 a, and the tip of the main body portion 15 b. And a barb 16 projecting outward from. And in the axial cylinder part 11, the slit 18 of the aspect cut | disconnected in the axial direction in the outer side of the root part 15a is formed in the connection part with the root part 15a of the latching claw 15 with a return | turnback. Further, a projection 17 having an oval cross section is provided projecting from the upper end surface of each blade 12, 12, 12.

  As shown in FIGS. 1 and 3, the decorative plate 30 is formed with pores 31 having substantially the same diameter as the narrow diameter portion 13 of the shaft tube portion 11 of the windmill member 10, and is returned around the pores 31. The three locking holes 32 with which the attached locking claws 15 are engaged are opened radially at 120 degree intervals with the axis of the small hole 31 as the center. A fitting hole 33 into which the projection 17 of each blade 12 is fitted at the time of assembly is also formed at a corresponding position of the decorative board 30. Further, on the back surface of the decorative plate 30, a protrusion row 34 that abuts on the upper side surface of the blade 15 at the time of assembly is protruded at a position sandwiching the fitting hole 33. The decorative plate 30 has the same number of the locking holes 32 and the protrusion rows 34, the fitting holes 33 are located on the center lines of the protrusion rows 34 and the protrusion rows 34, and on the center lines of the fitting holes 33. The protrusion row 34-the locking hole 32 and the locking hole 32-the fitting hole 34 are configured to have the same angle so that the locking hole 32 is positioned.

  Here, the decorative board 30 is formed of a disk integrally formed with a circular step portion 35 concentric with the pores 31 and having a concave portion 35a on the front surface side and a protrusion 35b on the back surface side. Each locking hole 32 is formed in a range on the center side of the circular step portion 35, and each protrusion row 34 is formed in a range outside the circular step portion 35. Further, the concave portion 35a on the surface side constituting the circular step portion 35 has a depth that is slightly larger than the length from the return 16 to the tip of the return locking claw 15. Further, the upper end surface of each blade 12 of the wind turbine member 10 is such that its center side portion 19a is flush with the upper end of the shaft tube portion 11 and the outer peripheral side portion 19b is in contact with the back surface of the decorative plate 30 during assembly. The stepped surface 19 corresponds to the shape of the back surface of the decorative plate 30.

  Moreover, the windmill member 10 and the decorative board 30 are formed by injection molding with a transparent synthetic resin.

  According to this windmill, since the locking claw 15 with the barbs is locked in a state in which the barbs 16 protrude from the surface of the decorative plate 30, the barbs 16 are narrowed in a direction to avoid the locking by the locking holes 32. It can be easily disassembled by deforming the locking claw 15 as if it were completely. Therefore, it is easy to change the decorativeness by replacing the decorative plate 30, and in that case, the windmill member 10 can be used in common.

  Further, at the time of assembly, the blade 12 is in a state in which the protrusion 17 is fitted in the fitting hole 33 of the decorative plate 30. Furthermore, each blade 12 is in a state in which the protrusion 17 is fitted into the fitting hole 33 and is also fitted between the protrusion rows 34. As shown in FIG. 9, when the nail 51 is attached to the game board 110, the upper and lower ends are supported while contacting the outer surface of the mounting nail, and the middle part does not contact the mounting nail, so that Rotate to. In addition, the protrusion 17 of the blade | wing 12 and the fitting hole 33 of the decorative board 30 may have some play, when fitted. This is because, in combination with being locked by the three hooking pawls 15, rattling that affects the rotation is unlikely to occur. Further, there may be some play in the fitted state of the blades 12 with respect to the ridge row 34. Rather, it is easier to perform disassembly and assembly if there is some play.

  In addition, the decorative plate 30 and the windmill member 10 can be assembled in contact with each other, and the locking claw 15 does not protrude from the surface of the decorative plate 30 at the time of the assembly, so that the height standard when assembled to the game board is clear. It becomes.

  Furthermore, according to the windmill 1 of the present embodiment, the locking claw 15 with a barb is formed with a root portion 15a extending outward from the upper end of the shaft tube portion 11, a main body portion 15b extending in the axial direction from the tip of the root portion 15a, It comprises a barb 16 projecting outward from the tip of the main body part 15b, and the shaft cylinder part 11 is connected to the base part 15a of the hooking pawl 15 with the outer side of the base part 15a in the axial direction. Since the slit 18 is cut into the shape, the latching claw 15 with the return is latched into the latching hole 32 of the decorative plate 30, and the latching claw 15 with the return is locked with the decorative plate 30. When being removed from the hole 32, the locking claw 15 is easily deformed inward and outward, and the workability of disassembly and assembly is good.

  In addition, the angle between the blade and the locking claw is set to 60 degrees so that each of the hooked locking claws 15 is located in the middle of the blade 12-12. Since the angle between the locking hole 32 and the fitting hole 33 is also 60 degrees, it is correct if the locking claw 15 is locked to the locking hole 32 in the assembly of the windmill member 10 and the decorative plate 20. It can be assembled in a positional relationship and is easy to assemble.

  In addition, since the windmill member 10 and the decorative plate 30 are made of a transparent synthetic resin injection-molded product, it is possible to visually recognize how the windmill 1 and the pachinko ball on the back side of the windmill 1 change the flow path. In such a case, the end face of the blade 12 that can be seen through appears to be a beautiful radial shape, so that the decorative effect due to the use of the light-transmitting synthetic resin is not hindered. Therefore, if the gaming board is also light-transmitting and a large liquid crystal display device is arranged, an image of a portion overlapping the windmill 1 can be visually recognized. In that case, the windmill 1 does not impair the decorativeness.

  Next, a pachinko machine to which the windmill 1 is attached will be described. In the description of the pachinko machine, “left” or “right” indicates “left” or “right” when viewed from the front side (front side) of the pachinko machine.

  As shown in FIGS. 4 to 9, the pachinko machine of the embodiment includes a game board 110, a back base 120 disposed on the back side of the game board 110, and a liquid crystal display device 130 attached to the back of the back base 120. I have.

The stage component 201 is a component for entering the back side of the game board 110, rolling the game ball that has passed through the warp route in the left-right direction, and finally guiding it forward as in the case of a normal pachinko machine. It is. The warp route is formed by a warp route component 180 fixed to the back side of the game board 110. Since the center window 111 of the game board 110 is located inward of the liquid crystal display viewing window 122 of the back base 120 in the left portion, the warp route component 180 is located inside the opening of the liquid crystal display viewing window 122. It is installed so as to face.

  As shown in FIGS. 7 and 8, the warp root component member 180 is a component that is injection-molded with a light-transmitting synthetic resin as a U-shaped cross-section component that is open on the front surface. Therefore, as described above, although it is installed so as to face the opening of the liquid crystal display viewing window 122, the image by the liquid crystal display device 130 behind it can be viewed from the front through the warp route constituent member 180. ing. In addition, the game ball passing through the warp route is visible through the game board 110.

  In this pachinko machine, as shown in FIGS. 4 and 9, the windmill 1 is attached so as to partially overlap the warp route component 180. Since the windmill 1 of the embodiment is made of a transparent synthetic resin molded product, the image of the large liquid crystal display device 130 behind can be seen through the windmill 1, the game board 110, and the warp route constituent member 180. it can. In this case, in this embodiment, the projections 34 and the like are arranged at equal intervals so that the end face of the blade 12 appears beautifully. There is no loss.
