Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a tree-shaped winning device.

(Prior art) Conventionally, the front end of a seesaw-type spherical guide plate has a pair of opening/closing wings, and the front end of the seesaw-type ball guide plate is pushed in and out between the opening/closing wings from the rear side of the mounting board, whereby both opening/closing wings can be operated at the same time. 2. Description of the Related Art Tulip-type winning devices that are configured to open and close are known.

However, when a tulip-type winning device with such a configuration is installed close to the side edge of the game board (the guide rail of the ball), when opening on both sides, the guide rail and the tip of the opening/closing wing on the side closer to this It is necessary to leave a gap between them through which the ball can pass. The reason for this is that if the gap is smaller than the diameter of the balls, the balls will fill the upper part of the gap and form a stone wall. Therefore, in the past, double-opening double-operated tube-type winning devices could not be installed based on the lateral dimension when both opening and closing wings were closed, but had to be installed using the radius of the longer opening and closing wings as a reference. Nakatsuta. In other words, the conventional double-opening ticket type winning device has a structure that is inappropriate for placement as close as possible to the side edge of the game board.

(Purpose of the invention) The object of the invention is to provide a tulip-shaped winning device in which only one side of a pair of wings is movable and can be placed closer to the side edge of a game board than before.

(Structure of the invention) The tube type winning device of the invention has only one of the two blades configured as a movable blade, and the front end of the seesaw type spherical guide plate is connected from the rear side of the mounting board. The present invention is characterized in that the movable blades are opened and closed by moving them in and out between the blades.

(Example) Hereinafter, the present invention will be explained based on the illustrated example.

FIG. 1 and FIG. 2 show a closed state and an open state of this tulip type winning device. 1 is a mounting board;
Approximately in the center thereof, there is an opening 2 extending vertically as a ball entrance. Two wing pieces 3 and 4 are provided on the surface of the mounting board 1 on both sides of the opening 2. One wing 3 is a fixed wing fixed to the mounting board 1, and the other wing 4 is a movable wing that can rotate around a shaft 5 to open and close. The wings 3, 4 are spaced apart enough to allow one ball to pass downward in the closed state shown in FIG. A guide passage 6 is provided at the lower part of the passage between the blades 3 and 4 to guide the ball passing downward from between the blades to the opening 2. In this embodiment, a front decoration covering the lower part of the blades 3 and 4 is provided. It is formed vertically in the center of the plate 7 and integrally with the front decorative plate 7.

The movable wing piece 4 is composed of a wing portion 4A that extends outward with the shaft 5 as the center, and a contact portion 4B that extends inward with the shaft 5 as the center. However, such a contact portion is not formed in the fixed wing piece 3. The fixed wing pieces 3 and the movable wing pieces 4 are formed bilaterally symmetrically.
In this embodiment, when viewed from the front with the movable wing 4 closed, the shape of the portion of the wing 3, 4 exposed from the front decorative plate 7 is in the shape of a quarter circular segment. ing. The movable wing piece 4 has a weight 8 to give it the ability to rotate outward, and the fixed wing piece 3 has a pseudo weight 9 to give it a symmetrical shape.
is provided.

In FIGS. 4 and 5, a frame 10 forming a side wall of the ball passage is provided on the back side of the mounting board 1, and within this frame 10 there is a see-saw type ball guide plate 1.
1 is supported by a shaft 12 so as to be rotatable in the front-back direction. As can be clearly seen from FIGS. 2 and 3, there are notches 1 on both sides of the tip 11A of the ball guide plate 11.
3 and 13 are provided, and this notch portion is located in a recess 4C provided inside the lower part of the movable wing piece 4. The rear end 11B of the ball guide plate 11 extends to a position where it can engage with a stopper 14 provided on the frame body 10. Further, as shown in FIG. 3, a return ball engaging piece 15 is provided below the ball guide plate 11 on the front side of the rotation center axis 5, and the tip of this ball engaging piece 15 is , into the guide passage 6 at the center of the front decorative plate 7. In this case, the tip of the ball engaging piece 15 is formed into a tapered shape so as not to interfere with the opening/closing operation of the movable wing piece 4.

When the movable wing piece 4 is closed, the spherical guide plate 11 is at rest in a slightly backwardly inclined state (FIG. 4), and its tip 11A is located in the recess 4C of the movable wing piece 4 and The opening operation of the piece 4 is prevented. Further, the return ball engaging piece 15 is located near the bottom of the guide passage 6 as shown in FIG.

If a ball enters the prize between the wings 3 and 4 which are in the closed state, the winning ball rolls backward on the ball guide plate 11 and pushes down the rear end 11B of the ball guide plate 11 (Fig. 2). ,
It exits from the outlet 10A provided in the frame 10. Due to the pushing down action of the rear end 11B of the ball guide plate by the winning ball, the tip 11A of the ball guide plate rises upward, and is pushed up by the pawl to open the movable wing piece 4 as shown in FIG. The opening angle of the movable wing 4 is determined by the outer rear end 4E of the movable wing 4 shown in FIG. 6 coming into contact with the return ball engagement piece 15 (FIG. 5). The open movable wing piece 4 is stabilized in this position by its own weight including the weight 8. In order to maintain this open state more stably, a magnet can be provided on one side of the stopper 14 and the lower surface of the rear end 11B of the ball conductive plate in contact with the stopper 14, and a magnetic material can be provided on the other side. In this embodiment, the stopper 14 is constructed as a magnetic pin, and a magnet 16 is provided on the lower surface of the rear end 11B of the ball conductive plate.

When the movable wing piece 4 is opened, the ball guide plate tip 11A
is retreated rearward to the extent that the ball can pass between the winglets 3 and 4. Further, the return ball engaging piece 15 rises diagonally with respect to the guide passage 6, as shown in FIG.
Therefore, when the movable wing piece 4 is open and a ball wins next time, the winning ball will hit the inner lower end 4 of the movable wing piece 4.
While pressing F (FIG. 6), it passes between the wing pieces 3 and 4 and falls into the ball guide passage 6. The ball that has fallen into the ball guide passage 6 rides on the returning ball engaging piece 15 protruding within the ball guiding passage 6, and flows out backward while pushing down the returning ball engaging piece 15. Therefore, the spherical guide plate 11 tilts from the state shown in FIG. 5 to the state shown in FIG. 4, and the tip 11A of the spherical guide plate pushes down the contact portion 4B of the movable wing 4, so that the movable wing 4 closes.

In this way, the movable wing piece 4 and the ball guide plate 11
oscillates between two stable positions each time a ball lands.

By the way, the reversal of the static position of the ball conductive plate 11, that is, the opening and closing of the movable blade 4 is performed by the blades 3 and 4 as described above.
In addition to the case where the ball enters between the balls, this can also be done by moving the rear end 11B of the ball guide plate up and down using a suitable switching drive means. For example, as shown in FIG. 7, the movable blade 4 can be opened and closed by protruding a lever 17 from the rear end 11B of the ball conductive plate and pushing down the lever with an electromagnetic solenoid 18 provided above. .

Further, it is preferable that the wing pieces 3 and 4 are made of a transparent or semi-transparent member, and that they are illuminated from the rear side of the mounting board 1 as necessary. In this example, the seventh
As shown in the figure and FIG. 8, lamp insertion holes 19 are provided in the mounting board 1 at both sides of the frame 10, a lamp 20 is inserted into the hole 19, and the lamp board 21 is inserted into the back side of the mounting board 1. It is screwed to a boss portion 22 provided in the.

9 and 10 show an example of application to a pachinko machine. FIG. 9 shows an example in which the main winning device 25 is placed on the sides of the two upper and lower chuckers 23 and 24. When the movable wing piece 4 is closed, the winning device 25 flows to the side of the movable wing piece 4 and almost reaches the chucker 24. The ball does not enter, but when the movable wing piece 4 opens, the ball enters the winning device 25 from between the movable wing piece 4 and the nail 26, and
The structure is such that the ball hits the tip of the movable wing, jumps between the nails 26, 26, and enters the chucker 24. FIG. 10 shows an example in which the main winning device 25 is disposed close to the ball guide rail 28, taking advantage of the fact that it is opened on one side. The wing piece on the side closer to the ball guide rail 28 is the fixed wing piece 5, so even if it is closer to the ball guide rail 28 than in the case of a conventional winning device in which this wing piece opens and closes, the winning device 25 and A ball passage space T can be provided between the ball guide rail 28 and the ball guide rail 28.

Although the above explanation has been made using a right-opening type winning device as an example, the present invention is not limited to this, and may be changed to a left-opening type winning device,
It is possible to use a combination of right-opening and left-opening winning devices. Therefore, it is preferable that this prize-winning device is configured so that as many common parts as possible are included. In this sense, the tip of the return ball engaging piece 15 is tapered so that it does not obstruct the opening/closing operation of the movable wing piece even if it is used in either a right opening type or a left opening type winning device. This is very important.

FIG. 11 shows an example in which a right-opening type winning device 25 and a left-opening type winning device 25' are provided on the left and right above the starting chucker 29 with a ball detector. Both prize-winning devices 25, 25' are arranged so that the movable wing pieces 4 are located inside each other. When both movable wing pieces 4, 4' are closed, the ball hits the outer surface of the wing piece, that is, the curved surface, and flows down, so it is easy to enter the starting hole chucker 29, but the movable wing piece 4,
When the ball 4' is opened, the ball is captured by the movable wing pieces 4, 4', making it difficult for the ball to enter the starting hole chuck car 29, thereby greatly increasing the player's interest in both benefits and harms.

(Effects) As described above, in the tube-type winning device of the present invention, only one of the two blades is configured as a movable blade, and the front end of the seesaw-type ball guide plate is connected to the mounting board. The movable blades are configured to open and close by moving in and out between the blades from the rear side. Therefore, compared to the conventional double-opening ticket type winning device, it can be installed closer to the side edge of the game board (ball guide rail).
