FIG. 4 is a perspective view showing a configuration of a conventional windmill for gaming machines. As shown in FIG. 4, a conventional windmill 100 for a gaming machine includes a blade plate 110 and a decorative rotating plate 120. The wing plate 110 has a cylindrical body (cylinder portion) 112 having a through hole having a diameter larger than the outer diameter of the game nail 130 at the center. A plurality of (for example, three) blades 110 are formed on the outer peripheral surface of the cylindrical body 112 at equal intervals. The decorative rotating plate 120 is a disc-like body in which a decoration 122 is provided on one surface (or the entire surface) and a through hole 114 larger than the outer diameter of the game nail 130 is formed at the center. The plurality of blades 110 having the cylindrical body 112 and the decorative rotating plate 120 are integrally formed by, for example, a plastic mold.
[0004]
In the gaming machine windmill 100, the game nail 130 is inserted into the cylindrical body 112 and the through hole 114 of the decorative rotating plate (decorative rotating portion) 120, and the game nail 130 is substantially perpendicular to the game board (not shown). Installed by hitting. Of course, when installing the windmill 100 for the gaming machine, the decorative surface of the decorative rotating plate 120 is arranged on the player side (front surface) and the blade plate 110 is arranged on the game board side. Therefore, the gaming machine windmill 100 rotates integrally around the game nail 130. In recent years, a windmill for a gaming machine has been put into practical use in order to further enhance the visual effect by providing an decoration device such as an LED in a decorative part.
[0005]
[Problems to be solved by the invention]
However, in the conventional windmill 100 for gaming machines described above, the entire windmill including the decorative surface of the decorative rotating plate 120 rotates together. Therefore, even if a complicated decoration is applied in the decoration state, the decoration part appears to be one by the rotation of the windmill itself and is monotonous. Moreover, it is difficult to maintain the rotating operation by the weight of the windmill itself. In addition, in a windmill for a gaming machine equipped with an electric decoration device, wiring is simplified by using a dedicated board, but failure is likely to occur due to a complicated structure, and inspection work and maintenance work are complicated. And since this kind of windmill for game machines becomes large compared with the windmill for conventional game machines mentioned above, there exists a problem that an installation place is limited.

[0009]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the configuration and operation of a preferred embodiment of a windmill for gaming machine according to the present invention will be described in detail with reference to the accompanying drawings.
[0010]
FIG. 1 is an exploded perspective view showing a configuration of a preferred embodiment of a windmill for gaming machine according to the present invention. As shown in FIG. 1, a windmill 10 for gaming machine according to the present invention includes a windmill body 20 including a blade portion 30 and a decorative rotating portion 40, and a decorative rotating body 60. The blade part 30, the decorative rotating part 40, and the decorative rotating body 60 have separate structures, but are integrated by a connecting part as will be described later and rotated to the game board of the gaming machine by the game nail 50. Installed as possible.
[0011]
The blade portion 30 includes a cylindrical portion 32 having a through hole 31 in the center, and a plurality (three in this specific example) of blade plates 33 formed radially on the outer periphery of the cylindrical portion 32. As will be described later, the blade portion 30 is rotatably attached to the game board of the gaming machine. The blade portion 30 is attached so that the right side shown in FIG. 1 is the game board side and the left side is the far end from the game board. A pin (cylindrical) connecting portion 34 is formed at a far end of, for example, the blade plate 33a, which is one of the blade plates 33, and at a position away from the through hole 31. The decoration rotating part 40 has a relatively thin disk shape, has a through hole 41 at the center thereof, and is decorated with a decoration 42 on the front surface.
[0012]
FIG. 2 is a diagram showing a detailed configuration of the decorative rotator 60 constituting the windmill 10 for the gaming machine shown in FIG. 1, and FIG. 2 (A) is a front view of the decorative rotator 60, and FIG. Is a cross-sectional view thereof. As can be understood from FIGS. 2A and 2B, the decorative rotating body 60 includes a plurality of (six in this specific example) blades 63 extending radially from a disk portion 62 having a through hole 61 in the center. It is a substantially snow-ice crystal shape (or substantially arrow wheel-like) flat plate member having a suitable decorative pattern (not shown) on its front surface (player side). The through hole 61 of the decorative rotating body 60 is substantially elliptical and is rounded on the inner wall thereof as shown in FIG.
[0013]
Next, with reference to FIG. 1 and FIG. 3, the assembly process and operation | movement of the windmill 10 for game machines by this invention are demonstrated. FIG. 3A is a front view of the decoration rotating unit 40. FIG. 3B is a cross-sectional view of the decorative rotating unit 40 and the blade unit 30. FIG. 3C is a rear view of the blade portion 30. First, the game nail 50 is inserted into the through hole 31 of the blade portion 30 and driven into a predetermined position of the game board of the gaming machine. At this time, the front end of the game nail 50 is prevented from substantially protruding forward from the front surface of the blade portion 30 (interference with the decorative rotating body 60 is prevented). Next, by inserting the through hole 61 of the decorative rotating body 60 into the connecting portion 34 of the blade portion 30, the decorative rotating body 60 is attached to be rotatable around the connecting portion 34. Finally, the blade part 30 and the decorative rotating part 40 are connected at the connecting part 34. Note that a suitable adhesive may be used for the connection at the connecting portion 34 between the blade portion 30 and the decorative rotating portion 40 constituting the windmill body 20. Alternatively, the front end of the connecting portion 34 may be inserted into an attachment hole (not shown) formed at a predetermined position of the decorative rotating portion 40 and bonded or heat welded. In this case, it is preferable that the mounting hole of the decorative rotating portion 40 and the front end shape of the connecting portion 34 be non-circular. As can be understood from FIG. 3 (B), the cylindrical portion 32 of the blade portion 30 is formed with a rounded protruding portion 35 on the game board side, thereby reducing the contact area with the game board. The contact resistance is reduced.
[0014]
With the configuration described above, the center of the decorative rotating body 60 is eccentric with respect to the centers of the blade portion 30 and the decorative rotating portion 40, that is, the game nail 50. Therefore, when the wing part 30 rotates due to the collision of the game balls, the decorative rotating body 60 also rotates in conjunction with the rotation of the wing part 30. However, since the center of rotation of the decorative rotating body 60 with respect to the decorative rotating unit 40 described above is eccentric from the center of rotation of the windmill body 20, the decorative effect of the windmill 10 for gaming machines can be enhanced. Note that a plurality of such windmills for gaming machines can be selectively attached within the gaming area of gaming machines such as pachinko machines.
[0015]
The configuration and operation of the preferred embodiment of the windmill for gaming machine according to the present invention have been described above in detail. However, this embodiment is merely an example of the present invention. The present invention is not limited at all. Those skilled in the art will readily understand that various modifications and changes can be made without departing from the scope of the present invention. For example, in the above-described preferred embodiment, one decoration rotating body 60 is used, but a plurality of decoration rotating bodies may be used with a thin thickness of the decoration rotating body. In that case, a common connecting portion may be used, or a plurality of connecting portions may be used. Furthermore, the decorative rotating body does not necessarily have a flat plate shape, and a rotating weight may be added to the tip of the decorative rotating body to make it irregular. Further, the connecting part 34 may be formed not on the blade part 30 side of the windmill body 20 but on the decorative rotating part 40 side. In that case, a relatively thin disk may be formed on the front end side of the blade portion 30 to facilitate connection. Furthermore, it is not always necessary to use a game nail for attaching the windmill body to the game board, and other similar attachment means may be used. Therefore, in the present specification, the “game nail” should be understood as a general term for such attachment means.
[0016]
【The invention's effect】
As can be understood from the above description, the windmill for gaming machine of the present invention has the following practically significant effects. That is, the blade portion and the decorative rotating portion are not integrally formed as in the prior art, but are coupled to each other with an eccentric substantially cylindrical connecting portion. Therefore, the connecting part has a plurality of functions as a connecting part that connects the blade part and the decorative rotating part at a distance, and as a rotating shaft of the decorative rotating body. Therefore, the decoration effect can be greatly improved by making the windmill body and the decorative rotating body eccentric and mutually rotatable.
[0017]
Further, according to the windmill for gaming machine of the present invention, for example, by using a thin or lightweight material, the decorative rotating body is made lighter than the windmill main body, so that the decorative rotating body can be operated even if the windmill main body stops operating. It is possible to further rotate and enhance the decoration effect. In addition, the contact area between the windmill body and the game board is reduced by the formation of the rounded protrusion, so that the rotation continues for a relatively long time due to the collision of the game ball with the blade.
