Description

  The present invention relates to an improvement of a windmill accessory that is arranged on a game board surface constituting a pachinko gaming machine and changes a flow path of game balls.

In pachinko gaming machines, various board parts such as a prize opening, a windmill accessory, a symbol display device, and an electrical decoration device are provided on the board surface of the game board in order to diversify the game contents.
The windmill accessory has a configuration in which the impeller is rotatably supported by a windmill shaft standing on the game board, and the impeller rotates when the game ball flowing down the surface of the game board abuts on the impeller blade. Thus, the production effect is exhibited, and the flow path of the game ball is changed by the interference by the blades (Patent Document 1).
FIGS. 5A and 5B are an exploded perspective view showing a configuration example of a conventional windmill accessory and a longitudinal sectional view of a finished product. The windmill accessory 100 is a resin impeller 102 that is rotatably supported by a windmill nail 101 projecting by being driven into the game board surface 110, and is fixed to the front surface of the impeller 102 to rotate integrally with the impeller. And a front plate 103 made of sheet metal (for example, Patent Document 1).
On the front of the front plate 103, symbols, characters, etc. related to the game content are displayed. However, if the symbols, etc. displayed on the front of the front plate have a vertical direction, the symbols are displayed when the windmill is stopped. It is preferable to configure so that the direction of is correctly oriented up and down.
However, when the front plate 103 rotates integrally with the impeller 102 as in the windmill accessory shown in FIG. 5 , the direction of the symbols on the front of the front plate is constant depending on the stop angle of the impeller when the rotation is stopped. In many cases, the stop state is not suitable for the directionality of the symbol or the like.

Patent Document 2 is configured such that the vertical direction of the pattern is always restored to the initial state when the windmill is stopped by attaching a weight to an impeller decorated with a vertical pattern or the like on the front surface. A windmill is disclosed.
By the way, for the effect of the gaming machine, there is a case where a request not to rotate these patterns may be generated when a pattern or the like having a vertical direction is drawn on the front surface of the windmill accessory. However, in the invention described in Patent Document 2, since the pattern rotates integrally with the windmill accessory, such a request cannot be satisfied. In particular, if the design stops when the top and bottom of the symbols are reversed, the appearance will deteriorate.

Patent Document 3 discloses a configuration in which an impeller is rotatably supported by a windmill shaft, and a front plate is fixed to a tip portion of the windmill shaft. According to this, even if the impeller rotates, it is possible to completely prevent the rotation of the front plate displaying the pattern having the vertical direction.
However, even if the impeller is rotatably supported by the wind turbine shaft independently of the front plate, there is a demand for not completely fixing the front plate displaying the pattern having the vertical direction to the wind turbine shaft. In such a case, the invention of Patent Document 3 cannot satisfy such a requirement.
That is, when there is a request to move the front plate as the impeller rotates, no windmill accessory that can satisfy such a request has been proposed.
JP 2002-200313 A Japanese Patent Laid-Open No. 10-085396 JP-A-11-114161

As described above, in the case of a windmill accessory used in a conventional pachinko machine, even if the pattern, characters, etc. displayed on the front of the windmill accessory have a vertical direction, the windmill accessory At the time of the stop, there was a bad appearance, such as the pattern upside down. In addition, there is a conventional example in which the front plate displaying the pattern is fixed to the wind turbine shaft while the impeller is rotatably supported, but according to this, it is desired to swing the front plate when the impeller rotates. Can't meet the demands of production.
The present invention has been made in view of the above, and in a windmill accessory provided with a front wheel depicting a pattern, characters, etc. having an up and down directionality and an impeller, when the impeller stops rotating, An object of the present invention is to provide a windmill accessory that can be stopped in a normal posture and can swing a front plate as the impeller rotates.

In order to achieve the above object, the invention of claim 1 is directed to a wind turbine shaft erected on a board surface of the game board, and a collision with a game ball that is rotatably supported by the wind turbine axis and flows down the board surface. A windmill accessory comprising: an impeller that freely rotates along with the impeller, and a front plate that is disposed in front of the impeller and is rotatably supported by the windmill shaft so as to be relatively rotatable with the impeller. The plate is provided with a displaced center of gravity structure for uniquely determining the rotational direction posture of the front plate when stopped, and at least one of the impeller and the front plate is provided with the rotation of the impeller. There is provided a biasing member that interferes with the front plate and biases it in the rotational direction, and the biasing member is directed from at least one blade constituting the impeller toward the back surface of the front plate. Projecting protrusions and / or protruding from the front plate toward the impeller Characterized in that it is a projection.
Since the impeller supported by the same wind turbine shaft and the front plate are independently rotatably supported, and the front plate is always stopped in a predetermined rotational orientation when stopped, the picture drawn on the front plate When the direction of characters is required, the player can visually check the picture or the like written on the front plate in a normal posture, and can eliminate the feeling of strangeness. “Uniquely defined” means that the posture of the front plate that rotates or rotates almost returns to the original vertical orientation determined based on the direction of the symbol displayed on the front surface or the shape of the front plate. Means that .

Not always than stopping the front plate which rotates independently of the vanes, as possible out be rotated by the rotational force from the blade plate.

According to the present invention, the front plate is supported so as to be rotatable independently of the rotating vane plate, and the front plate is stopped when the symbols, characters, etc. drawn on the front plate have a vertical direction. Sometimes the vertical direction of the symbol and the like can be maintained in a normal posture.
In other words, the fact that the front board is completely stopped during play is a cause of halving the visual fun. By turning (swinging) or rotating the front plate, it is possible to realize the fun that the pattern or the like cannot be discriminated. On the other hand, when the front plate stops, the sense of incongruity can be eliminated by stopping the picture or the like in a normal vertical position.
Since the center of gravity is located at the position corresponding to the lower part of the front plate, etc., so that the posture of the design drawn when the front plate stops is in a normal state, the design etc. when the front plate stops The vertical direction of can be maintained in a normal posture.
The displaced center-of-gravity structure can be realized by making a part of the front plate a different material such as a heavy metal or by increasing the thickness of a part of the front plate.
Alternatively, the position of the center of gravity may be shifted downward by making the shape of the front plate asymmetric.

Hereinafter, the present invention will be described in detail with reference to embodiments shown in the drawings.
FIG. 1A is a perspective view showing a configuration of a windmill accessory according to an embodiment of the present invention, FIG. 1B is an exploded perspective view thereof, and FIG. 1C is a cross-sectional view of the windmill accessory installed on a game board surface. FIG.
The windmill accessory 1 is set on the game board surface of the pachinko gaming machine and includes an impeller that rotates when the game ball comes into contact with it, thereby slowing down the fall speed of the game ball and changing the direction of the game. The above-mentioned interest is raised.
The windmill accessory 1 is made of resin having a windmill nail (windmill shaft) 2 erected by being driven into a game board surface 40 made of a plywood board or an acrylic board, and a shaft hole 10 a inserted through the windmill nail 2. An impeller 10 and a front plate 20 pivotally supported by a center hole 20a by a windmill nail 2 on the front side of the impeller 10 are provided.
The impeller 10 has a configuration in which a plurality of blades 12 protrude from the central shaft portion 11 in the outer diameter direction, and can freely rotate in accordance with a collision with a game ball flowing down the game board surface.
The front plate 20 in this example is a circular plate, and the center hole is rotatably supported by the windmill nail 2 and is positioned by a stopper ring 25 made of metal, resin or the like so that the axial position does not move. The front plate 20 can rotate independently (relatively) from the impeller 10. In addition, on the front surface of the front plate 20, a character 21 having a vertical direction is displayed. In addition, what kind of thing may be used for the front board front surface as long as it is not only a character but arbitrary symbols, and has the up-and-down directionality (top and bottom).

The front plate 20 is inserted into the windmill nail 2, the stopper ring 25 is fixed to the windmill nail 2, the front plate 20 is assembled so as to be rotatable and not displaced in the axial direction, and then the shaft hole 10a of the impeller 10 is formed. By inserting the windmill nail into the game board surface 40 by driving the tip of the windmill nail 2 protruding from the rear surface of the impeller 10 in a state where the assembly of the windmill accessory 1 is completed, the windmill accessory can be installed. Complete.
The characteristic configuration of the present invention is arranged in front of the impeller 10 and the impeller 10 that is rotatably supported by the windmill nail 2 and that freely rotates in accordance with the collision with the game ball flowing down the board surface 40. In addition, in the windmill accessory provided with the front plate 20 that is pivotally supported by the windmill shaft so as to be rotatable relative to the impeller, the front plate 20 uniquely determines the rotation angle (rotational direction posture) of the front plate when stopped. The point of having a displaced center of gravity structure.
Note that “uniquely defined” means that the posture of the front plate that rotates or rotates is substantially the original vertical orientation determined from the directionality of the symbols displayed on the front surface or the shape of the front plate. It means to return.

In the present embodiment, the displaced center-of-gravity structure is realized by the weight member 22.
The weight member 22 is composed of, for example, a heavy metal such as a metal fixed at one location along the periphery of the front plate 20 having a uniform plate thickness, and the front plate surface depends on the weight of the weight member 22 when the front plate 20 is stopped. The character 21 is fixed to the lower part of the character 21 so that the vertical direction of the character 21 is in the normal state shown in FIGS.
Or you may implement | achieve the center-of-gravity structure displaced by comprising only a part of front board 20 with a metal material.
Furthermore, in the present invention, in order to transmit the rotational force of the impeller 10 rotated by the collision of the game ball to the front plate 20 and to swing it, the impeller 10 or the front plate 20 is provided with at least one of the impellers. There is provided a biasing member 30 that interferes with the front plate 20 during the rotation of 10 and biases it in the rotational direction.
FIGS. 3A and 3B are an exploded perspective view of the windmill accessory 1 according to the embodiment including an urging member, and a cross-sectional view of the windmill accessory installed on the game board surface.

In the present embodiment, the urging member 30 includes a protrusion 31 projecting from at least one blade 12 constituting the impeller 10 toward the back surface of the front plate 20, and movement of the impeller blade 12 from the front plate 20. This is a protrusion 32 protruding toward the locus. Both protrusions 31 and 32 are formed in a hemispherical shape, and when the impeller rotates, the tops of the protrusions lightly come into contact with each other, thereby pressing the front plate 20 in the rotation direction by a predetermined angle by the impeller-side protrusion 31. Thus, the projection 32 is detached from the projection 31 and only the impeller continues to rotate. While the projection 31 on the impeller side presses the projection 32 on the front plate side, the front plate rotates in the same direction, but after the projection 31 passes through the projection 32, the reverse for returning to the original position. Rotate in the direction. For this reason, the front plate repeats the operation of swinging left and right as the blades rotate.
Specifically, for example, the front plate 20 is configured to be able to advance and retreat by a predetermined axial distance by the stopper ring 25, so that the protrusion 31 is released from the protrusion 32 after pressing the protrusion 32 in the rotation direction. It is preferable to make it easy to configure. At this time, for example, the front plate is always elastically biased rearward by an elastic material (not shown) such as rubber or resin disposed between the head of the windmill nail 2 and the recess 23 provided on the front surface of the front plate 20. You may comprise as follows.

In the above embodiment, the projections are provided on both the impeller and the front plate. However, the front plate may be swung by the action of the projection provided on only one of them.
As the protrusions 31 and 32, for example, a resin material such as urethane having low frictional resistance is preferable.
In the above embodiment, the front plate 20 is rotated (swinged) by the impeller 10, but the front plate may be rotated. In this case, it is possible to add interest that makes the pattern unreadable.
In the windmill accessory according to the above-described embodiment, the impeller and the front plate are rotatably supported by the windmill nail 2 driven into the game board surface 40, but are fixed to the game board surface 40 with screws as shown in FIG. The impeller 10 and the front plate 20 may be rotatably supported by a wind turbine shaft 51 protruding from the base plate 50. Unlike the windmill nail of FIG. 1, the windmill shaft 51 is not driven into the game board surface, but is integrally formed with the base plate 50.

Next, FIG. 4 is a front view showing the configuration of a windmill accessory according to another embodiment of the present invention. This windmill accessory 1 uniquely determines the vertical position of the front plate 20 when rotation is stopped. The center-of-gravity structure that is displaced to achieve this is realized by making the shape of the front plate itself an asymmetric shape (vertical asymmetric structure).
First, the wind turbine won game 1 of FIG. 4 (a), by adopting the structure Asymmetric the projection 60 provided on the outer periphery of the circular body as a front plate 20, projecting upon rotation of the impeller 10 (not shown) stops The front plate 20 is configured to stop with the portion 60 facing downward.
Figure 4 windmill won game 1 (b), by employing the structure Asymmetric provided with protrusions 60 on the outer periphery of the elliptical body as front plate 20, projecting upon rotation stop of the impeller 10 (not shown) section The front plate 20 is configured to stop in a state where 60 is directed downward.
Figure 4 windmill won game 1 (c), by adopting the structure Asymmetric provided with protrusions 60 at the corners of the square body as front plate 20, projection 60 during rotation stop of the impeller 10 (not shown) The front plate 20 is configured to stop in a state in which is directed downward.
FIG. 4 (d) without providing the protruding portion, by devising the shape of the front plate itself, always front plate 20 in a state facing the predetermined vertical direction is configured to stop.

As a result of this configuration, the vertical posture at the time of stopping can be uniquely determined by the weight balance of the front plate itself without adding a weight member, and is matched with the directionality of the displayed symbol 21 or the like. be able to.
In addition, you may add a weight member to the protrusion part 60 as needed.
As described above, in the present invention, when the front plate is moved in the rotation direction by the rotation of the blade plate, the displaced center of gravity structure is provided for uniquely determining the rotation direction posture of the front plate when the front plate is stopped. It was. In other words, the impeller and front plate supported by the same wind turbine shaft are rotatably supported independently, and when the front plate stops, it always stops in a predetermined rotational orientation. When there is an up-and-down direction in the picture, character, etc. 21, the player can visually check the picture or the like written on the front board in a normal posture, and can eliminate a sense of incongruity.

Further, since the displaced center of gravity structure is constituted by the weight member 22 provided on the front plate, the stop posture of the front plate can be controlled to be constant only by adding a weight to the eccentric position of the front plate. .
In addition, since the center of gravity structure is configured by making the shape of the front plate asymmetrical, the stop posture can be controlled to be constant by the weight balance of the shape of the front plate itself without attaching a weight to the front plate. Can do.
Further, since at least one of the impeller and the front plate is provided with a biasing member that interferes with the front plate and biases it in the rotation direction when the impeller rotates, independently of the blade plate The rotating front plate is not always stopped, but can be rotated by the rotational force from the blade plate.

According to the present invention, the front plate is supported so as to be rotatable independently of the rotating vane plate, and the front plate is stopped when the symbols, characters, etc. drawn on the front plate have a vertical direction. Sometimes the vertical direction of the symbol and the like can be maintained in a normal posture.
In other words, the fact that the front board is completely stopped during play is a cause of halving the visual fun. Therefore, in the present invention, by turning (swinging) or rotating the front plate, it is possible to realize the fun that the pattern or the like cannot be discriminated. On the other hand, when the front plate stops, the sense of incongruity can be eliminated by stopping the picture or the like in a normal vertical position.
Since the center of gravity is located at the position corresponding to the lower part of the front plate, etc., so that the posture of the design drawn when the front plate stops is in a normal state, the design etc. when the front plate stops The vertical direction of can be maintained in a normal posture.
The displaced center-of-gravity structure can be realized by making a part of the front plate a different material such as a heavy metal or by increasing the thickness of a part of the front plate.
Alternatively, the position of the center of gravity may be shifted downward by making the shape of the front plate asymmetric.
The windmill accessory of the present invention can be used in general pachinko gaming machines and other gaming machines using game balls.
