Description

[Detailed Description of the Invention] This invention relates to a winning ball device, and particularly to a new winning ball device that is used by being disposed on a game board of a pinball game machine that uses pachinko balls to play games.

Among the conventionally known winning ball devices of this type, for example,
There is one described in Publication No. 35024, in which a winning ball device called a chulip was placed on a game board. This tube is equipped with two ball receiving pieces (or ball receiving parts) that can be rotated left and right, and under normal conditions, both ball receiving pieces are arranged at a distance that allows one pachinko ball (hereinafter referred to as a ball) to pass through. The ball is closed with the ball held in a nearly vertical direction, and the ball receiving pieces are opened to the left and right in response to a winning ball to receive the subsequent falling ball.

However, in conventional chulips, when either the left or right ball receiving piece accepts a ball, the condition for closing the ball receiving piece from a state where it is easy to win by opening the ball receiving piece is to open both ball receiving pieces. It is closed. For this reason, the conventional tulips could only guarantee one winning ball when the ball receiving piece was open, and could not provide any service to the player. It should be noted that with conventional chulips, it is possible to generate multiple winning balls while opening the left and right ball receiving pieces once, but in order to do so, it is necessary to create two winning balls at the same time while opening the ball receiving pieces. This required a high level of gaming technology.

In addition, in the conventional chulip, as another condition for opening the ball receiving piece, there are cases where the ball receiving piece is opened electrically in response to a winning ball hitting a certain safe hole on the game board. In this case, when the left and right ball holder pieces are closed, a swingable path is provided to guide the winning ball to the back side, and this path is electrically driven to create the same state as the winning ball. This is done by causing However, in this case, there was a problem that jams were likely to occur unless the electrical drive was stopped after the passage was once tilted. This is because, if the passage continues to be tilted electrically, the balls received by the ball receiving pieces will not be collected to the back side, and will remain stuck in the state of being received by the ball receiving pieces. Therefore, even when the conventional ball tip is electrically driven to open based on certain conditions, it has not been possible to continuously produce a plurality of winning balls.

Moreover, in this type of conventional winning ball device,
The probability of winning a ball is 2 when both balls are fully open and when both balls are closed.
Only the types changed, making the game less interesting.
In other words, for players, the biggest concern is the probability of winning a ball in the winning ball device, and since the winning probability only changes in two ways, the drawback is that the game cannot be made any more interesting. It was hot.

In view of these circumstances, this invention aims to improve the service to players by guaranteeing at least two winning balls with one opening, while increasing the types of winning probabilities of balls and providing variations. To provide a winning ball device that allows rich games.

The winning ball device according to the present invention has at least an opening formed in its front surface and a mounting member that is attached to the game board, a pair of mounting members rotatably provided on both sides of the mounting member, sandwiching the opening of the mounting member. A ball receiving member that receives pachinko balls and guides them to the opening by opening, and when the pair of ball receiving members are simultaneously opened by the operation thereof, and a pachinko ball is received by either one of the ball receiving members. An opening/closing mechanism is provided that closes the ball receiver member that receives the pachinko balls in conjunction with the movement of the pachinko balls, so that the pair of ball receiver members are simultaneously opened and the ball receiver member that receives the pachinko balls is closed. It is characterized by being configured to be closed individually.

The present invention having such a configuration has the following effects.

In other words, if a pachinko ball is accepted into a pair of ball receivers that are opened at the same time by the operation of the opening/closing mechanism, only the accepted ball receiver will be closed, and the other ball receiver will be closed. It still maintains an open stance. Only when a pachinko ball is received by the open ball receiving member, both ball receiving members assume the closed position. In other words, in the middle of the change of the winning ball device from the fully open state to the closed state, a half-open state is created in which only one ball receiver member is closed, and at least two winning balls are generated by one opening. can be caused.

Furthermore, the probability of winning a ball can be changed into three types depending on whether the winning ball device is in a fully open state, a half-open state, or a closed state, and the enrichment of winning probabilities enables a game with a wide variety of variations.

Furthermore, even if there are a plurality of winning balls while the pair of ball receiving members are open, the winning ball device is in the closed state after being in the half-open state at one end, making it difficult for balls to become jammed.

Hereinafter, specific embodiments of this invention will be described with reference to the drawings.

A tilt passage 131 included in the opening/closing mechanism 13 is provided on the bottom surfaces of the guide wall 114 and the side wall 116 and is rotatably supported by a shaft 117 . A pressing protrusion 131a is fixed below the rear end of the tilting passage 131. Furthermore, spacers 118 are formed on both sides of the opening 112 on the back side of the mounting member 11 for mounting an opening/closing mechanism 13, which will be described later.

The ball bearing members 12L and 12R are formed symmetrically. These ball receiver members 12L and 12R are comprised of a ball receiver piece 121 that protrudes from the front of the mounting member 11 and a ball receiver piece 121 that appears on the front surface of the mounting member
1 is integrally formed with the back side portion of the main body. When the ball receiving piece 121 is closed, the outer surface thereof is formed into an arc shape, and the inner surface thereof is formed into a straight line shape. A hole 122 is formed at the base of the ball receiving piece 121 to allow the shaft to pass therethrough.
A plate-shaped portion 123 is formed in the lower portion of the ball receiving piece 121 so as to have a certain angle (for example, 120°) with respect to a surface that becomes inside when the ball receiving piece 121 is closed. This plate-shaped portion 123 includes the ball receiving member 12L,
When 12R rotates and opens the ball receiving piece 121, it is pushed down by the received ball and the ball receiving piece 12
It functions to rotate the ball bearing members 12L and 12R so as to close the ball bearing members 12L and 12R. A stopper piece 124 is formed on the back surface of the plate-shaped portion 123 to prevent the ball from rolling backward. In addition, each ball bearing member 12
A pin 125 for maintaining the closed state is formed on the end surface of the back surface of the plate-like portions 123 of L and 12R. In addition, the mounting member 1 of the ball bearing members 12L and 12R
1 is provided with a weight 126 for rotating the ball bearing members 12L and 12R when the restraint state of the pin 125 is released. In the ball bearing members 12L and 12R configured in this way, with the shaft 127 inserted into the hole 122, one end of the shaft 127 is supported by a bearing portion 119 formed on the front cover 113, and the shaft 127 is The other end is supported by a bearing portion 133 of a mounting plate 132 included in the opening/closing mechanism 13, which will be described later, so that it is rotatably mounted.

The opening/closing mechanism 13 includes a mounting plate 132. This mounting plate 132 includes a stopper 133 and a shaft 1.
34, 135, 136, 137 are formed. The shaft 134 rotatably supports an opening/closing crank 138. The shaft 135 rotatably supports an opening/closing crank 139. This opening/closing crank 138 and 139
is constructed by having mutually opposing parts formed in a C-shape, and a weight fixed to a part outside the fulcrum supported by the shaft 134 or 135. An L-shaped lever 141 is supported on the shaft 136. An L-shaped lever 142 is supported on the shaft 137. The upper ends of the L-shaped levers 141 and 142 form inclined portions, and are engaged with respective G-shaped portions of the corresponding opening/closing cranks 138 and 139. L-shaped lever 1
The other ends of 41 and 142 each form a protrusion in the upper portion. This L-shaped lever 141,1
The ball receiving member 12 to which the protruding portion at the other end of 42 corresponds
It selectively engages with the pins 125 of L and 12R.

Below the opening 112 and the mounting member 1
A recovery passage 15 for recovering the balls that have entered the opening 112 is formed on the back surface of the ball 1 . The recovery passage 15 is constructed by forming a U-shaped member 151 in the lower part of the opening 112 when viewed from the back, and by vertically standing a partition plate 152 in the center thereof. By providing the partition plate 152, the ball receiving member 12L
The ball received by the ball receiving piece 121 and the ball receiving member 12R
The balls received by the ball receiving piece 121 are collected to the back side through separate passages. In addition, the U-shaped member 15
1 is formed with an inclined protrusion 153 that becomes lower from the front side to the back side in order to make it easier for the ball to roll.

Next, the operation of the winning ball device 10 of this embodiment will be explained.

Figures 5A and 5B show ball bearing members 12L, 1.
FIG. 5A is a diagram showing the open state of 2R, in particular, FIG. 5A shows its front view, and FIG. 5B shows its rear view.

FIGS. 6A and 6B show one ball bearing member 12.
FIG. 6A is an illustrative view of R in a closed state, in particular, FIG. 6A shows its front view, and FIG. 6B shows its back view.

For example, as shown in FIGS. 1A and 1B, when a ball enters the winning opening 11 with the ball receivers 12L and 12R closed, the ball rolls on the tilting path 131 and moves to the back side. be led to.
At this time, due to the weight of the ball, the tilting passage 131 tilts as shown in FIG. 4, and the opening/closing cranks 138, 1
Press the C-shaped part 39. Therefore, the C-shaped portions of the opening/closing cranks 138 and 139 are pushed downward, and the corresponding L-shaped lever 14
Rotate the other end of No. 1,142 downward. As a result, the engagement state between the other ends of the L-shaped levers 141 and 142 and the corresponding pins 125 of the ball bearing members 12L and 12R is released. depending on,
Each ball bearing member 12L, 12R is rotated to the left and right by the action of the weight 126. This situation is shown in FIGS. 5A and 5B.

As described above, when the ball receiving members 12L and 12R rotate to open the ball receiving piece 121, it becomes easier for the falling balls to win a prize. At this time, when the ball receiving piece 121 of either one of the ball receiving members (for example, 12R) receives a ball, the ball is transferred to the plate-shaped portion 1 of the ball receiving member 12R.
23 is pushed down, it passes through a passage sandwiched between the U-shaped member 151 and the partition plate 152, and is recovered to the back surface. At this time, the ball receiving piece 121 of the ball receiving member 12R
When the ball received in passes through, the ball receiving member 12R rotates in the opposite direction to the opening direction, and closes the ball receiving piece 121. In this way, in the winning ball device 10 of this embodiment, only the ball receiving member (12R) that receives a ball is closed, and the ball receiving member (12L) that does not receive a ball continues to be in the open state. And the ball is the ball receiving piece 121 of the ball receiving member 12L.
When received, the ball receiving member 12L is rotated in the closing direction. Therefore, in the winning ball device 10 of this embodiment, the pair of ball receiving members 12L, 12R are 1
When the number of winning balls is opened, it can be guaranteed that at least two winning balls will be won, which has the advantage of improving the service.

Note that instead of the partition plate 152, a rod-shaped one may be used. In that case, a pair of ball bearing members 1
When 2L and 12R are opened, the plate-shaped portion 12
3, a rod-shaped member may be provided along the depth direction at a position slightly lower than the diameter of the ball and at the center of the left and right ball receiving members 12L and 12R.

By the way, in the above-mentioned embodiment, the ball bearing member 12
Although the case where a ball enters the winning hole 111 has been described as a condition for opening L and 12R at the same time, the opening may be performed based on other conditions without being limited to this.

FIG. 7A is an illustrative view of a winning ball device 20 according to another embodiment of this invention, in particular, FIG. 7A shows a perspective view as seen from the back, and FIG. 7B shows a back view. In the winning ball device 20 of this embodiment, the opening mechanism includes a solenoid 21, which is an example of an electric drive means, in addition to the opening mechanism 13 of the above-described embodiment. That is, the mounting member 11 includes:
Solenoid 21 is installed. A short side of an L-shaped lever 23 is fixed to the plunger 22 of the solenoid 21. The long side of the L-shaped lever 23 is slidably supported. A pressing piece 24 is fixed to the tip of the long side of the L-shaped lever 23. An engagement pin 25 is fixed to the side surface of the end of the tilt passage 131 in the depth direction.

In operation, the winning ball device 20 of this embodiment
is based on the detection of a ball that has passed through a specific winning hole or passage area formed on the game board.
Solenoid 21 is electrically energized. depending on,
The solenoid 21 pushes down the L-shaped lever 23 and the pressing piece 24 pushes down the engagement pin 25, thereby forcibly rotating the tilting passage 131 in the same way as when a winning ball is hit. This opens the ball bearing members 12L and 12R.

In addition, in the winning ball device 20 of this embodiment, if the solenoid 21 is continuously energized, the tilting passage 131
The crank 13 is continuously opened and closed by the pressing protrusion 131a.
Since the C-shaped portion of 8,139 is continued to be pressed, even if the ball is received by one of the ball receiving members, the L-shaped lever 141 or 142 and the pin 125 do not engage, so the ball that received the ball does not engage with the pin 125. The receiving member can open again and maintain a continuous open state. In this case, the ball receiving member that received the ball is once closed and then reopened, and the ball is transferred to the recovery passage 15.
There is also the advantage that clogging can be prevented since the particles are collected through the .

By the way, in each of the above-mentioned embodiments, a case is shown in which one mounting member 11 is provided with a pair of ball bearing members 12L, 12R and an opening/closing mechanism 13. A pair of ball bearing members and an opening/closing mechanism may be provided. In this way, there is an advantage that a plurality of winning ball devices can be attached to the game board in one attachment operation.

In addition, in this embodiment, the ball receiver members 12R and 12L are operated by winning a prize in the winning hole 111 provided on the upper part of the mounting member 11, but the present invention is not limited to this. Instead, the ball receiver members 12R, 12L may be configured to operate based on a winning ball won from between the ball receiver members 12R, 12L.

As described above, according to this invention, it is possible to reliably guarantee that a plurality of winning balls will be generated by opening one set of ball receiving members once, and it is possible to improve the service to players, and By increasing the types of winning probabilities, unique effects such as enriching the variations of the game and improving interest can be achieved.
Moreover, even if a plurality of winning balls are present while a pair of ball receiving members are open, ball clogging can be prevented from occurring.
