Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention is applicable to a winning machine installed on the game board surface of a pachinko machine. L
Regarding location.

[Prior Art 1] As is well known, the game board of a pachinko machine is equipped with a winning device that receives a ball hit from a firing device and uses it as a valid ball (safe ball). In addition to determining whether the winnings are good or bad, this winning device changes the game by changing the winning conditions, which has a great effect on interest in the game. For this reason, many proposals have been made and various devices have been provided, but the winning device of the present invention is particularly equipped with a door that opens and closes at the entrance, and prizes can be won by opening and closing the door. Concerning prize-winning devices that may or may not work.

Conventionally, there are wing-shaped devices and groove-shaped devices that change winning conditions by opening and closing a door. In general, the wing-shaped ones rotate left and right around a single fulcrum, which opens and closes the entry hole, and makes it easier to win prizes by protruding outward and catching falling batted balls. However, for the groove type type, the door is hinged to the opening that opens toward the front, and the door is usually left standing and the opening is closed, and you can also win prizes. At the same time as opening the opening, the door is made to protrude almost horizontally from the front of the game board, thereby making it easier to catch the ball and greatly relaxing the winning conditions, thereby making it possible to win big prizes. There is.

The present invention relates to improvements to this door-type winning device, and in particular, this invention improves the door provided at the opening that serves as the entrance.

As mentioned above, the door conventionally installed at the opening normally closes the opening by standing up, making the flight of the ball completely unbalanced in this state, but when the door is tilted forward and opened, the opening is closed. In addition to making it possible to enter the ball, this door, which is tilted forward, can be used as a cradle and guiding platform for the ball to greatly ease the entry conditions, making it possible to win a prize in the heavens. However, the door of conventional prize winning devices is narrow. Therefore, the opening closed by this door had to be narrow as well.

In other words, the door in the winning device generally has a pivot joint along the lower edge of the opening, and the free upper end is tilted forward using this pivot joint as a fulcrum, and the door is tilted slightly inward from the horizontal position. The ball receiver is designed to allow entry, but this door must be limited to the space provided in front of the game board, that is, the space between the game board and the glass plate that covers the front of the game board. Therefore, the opening closed by this door also follows the size of this door, and it is not possible to make a large opening, especially an opening that is wide vertically. [Problems to be solved by the invention] The present invention was researched and developed in order to revise this in view of the above-mentioned conventional situation, and its purpose is to completely cover up the entry opening, which is wide open up and down, when it is closed. In addition, when the door is opened, the door can be horizontally housed in a narrow space restricted by the game board and the glass plate, making it possible to catch and guide batted balls, and when the door is opened, the entire opening can be opened. To provide a winning device for a pachinko machine that makes it easy to look into the inside and make it easy to see the movement of a pachinko machine.

[Means for Solving the Problems] That is, the present invention has been made based on the above-mentioned object, and its feature is that the opening that opens toward the front can be freely refracted via a horizontal pivot axis. Upper and lower door plates are pivoted to the opening, and when closed, the door plates are extended flat to close the opening, and when opened, the upper and lower door plates are bent about the pivot shaft to close the opening. To provide a winning device for a pachinko machine which allows a ball to enter by opening the door and protruding an upper door plate to the front of the opening.

[Function 1] The device of the present invention opens and closes the door mainly in accordance with instructions from the outside, similar to conventional general prize-winning devices.
When an opening instruction is received, this is transmitted to the upper door plate which is pivoted via the lower door plate and the pivot shaft using a solenoid, etc., and the upper door plate is pushed down and bent around the pivot shaft as a fulcrum. The opening is opened along with this refraction.

At the same time, the upper door plate is made to protrude forward, making it possible to receive and receive the ball. When the opening is closed, the upper door plate is pulled off using a solenoid or a spring force, and the bend with the lower door plate is extended accordingly, thereby closing the opening.

Next, an embodiment illustrating the winning device according to the present invention will be described in detail to clarify its characteristics.

[Example] Fig. 1 is a front view in the closed state, Fig. 2 is a right side view of the same 1-, Fig. 3 is a right side view of the center longitudinal section of the same, and Fig. 4 is a front view in the open state. , FIG. 5 is a right side view of the center longitudinal section of the same as above.

In the drawing, l is a mounting board for the winning device that has a horizontally elongated opening 2 in the center, and 3 is a box-shaped ball holder with a hollow interior and a passage 4, which is integrally provided behind this mounting board. A frame body, 5a.

Reference numeral 5b indicates upper and lower door plates provided to close the first entrance part 2.

In this embodiment, the door plates 5a and 5b are formed into horizontally elongated plates that roughly divide the opening 2 into upper and lower halves, and bearing parts 6.7 are provided alternately at the upper and lower edges of the two. A pivot shaft 8 is inserted horizontally through the bearing portion of the lever, and the pivot shaft 8 is pivoted in a hinge-like manner and assembled as one unit. Then, shafts 9 are provided at both ends along the lower edge of the lower door plate 5b, and are pivoted to bearings 10 provided on the back side of the left and right lower ends of the opening 2, and the lower door is mounted using the bearings 10 as a fulcrum. A plate 5b is attached so that it can be opened and closed freely, and pins 11 are provided protruding from both left and right ends along the E edge on the other upper door plate 5a, and the pins 11 are attached to the box-shaped frame 3 along the left and right edges of the opening 2. It is held so that it can slide freely up and down by slidingly fitting into slits 12 vertically provided on the left and right side wall surfaces.

13 is a solenoid for opening and closing the door plates 5a and 5b, and 14 is a swing arm that transmits the operation of the solenoid to the door plate.

The swinging arm 14 is attached to one side wall of the frame 3 so as to be able to swing freely about a shaft 15 as a fulcrum, and has a plunger 18 of the solenoid 13 connected to it in the middle of its length, and has a fork 17 formed at its free swinging end. One pin 11 slidably fitted into the slit 12 is engaged to connect the solenoid 13 and the door plate.

In this embodiment, a spring 18 is contracted to the plunger 1B of the solenoid, and the plunger is normally raised by the urging force of this spring, and accordingly, the plunger is raised via the pin 11 that engages with the swinging arm 14. The upper door plate 5a is pulled up to close the opening 2.

In this state, an opening command is received from the outside like in the conventional winning device, and when the solenoid 13 is energized by the signal and the plunger 18 is lowered, the pin 11 guides the slit 12 through the swinging of the swinging arm 14. Pushed down.

Figures 4 and 5 show that the upper and lower door plates 5a are pressed down by this pin.
, 5b shows the state in which the pin 11 is bent in a bent shape using the pivot point (pivot shaft 8) as a fulcrum and the opening 2 is opened.
When the door descends, the upper and lower door panels bend into a bent shape.

The pivot portion is projected forward and folded in two to open the entire opening 2.

Then, the door plate 5a is bent and protrudes forward.

5b (mainly the upper door plate 5a) forms a platform, which receives the falling ball and guides it into the opening. In addition, 19 in the figure is a glass plate.

The door plate opened in this way becomes a solenoid when a set time elapses or when a release command is received. 3 is demagnetized, the spring 18 acts again to return to the closed state described above.

Fig. 6.7 shows that the bending direction of the pivot joints of the upper and lower door plates 5a and 5b is reversed from that of the above embodiment, so that the upper half of the upper door plate 5a is projected inside the opening. This is another embodiment in which the receiver that projects forward is a stand.

In this embodiment, the lower door plate 5a has a larger width in the height direction than the lower door plate 5b, and in order to make the upper half protrude forward, pin 1! The position of is moved to approximately the center of the side edge.

[Effects of the Invention ff11 In the winning device of the present invention, as explained in the above two embodiments, the bending directions of the pivot joints between the lower two door plates are different from the inside and outside, but in both cases, the opening 2 The door plate shall be closed by two upper and lower door plates, and when opening the door plate, the door plate should be folded down and the upper door plate should be pushed forward at the same time as the door plate is opened. It forms a pedestal for the ball and allows it to fly into the opening, and while it has exactly the same mechanism as the conventional winning device made of a single plate, in the present invention, the folded ball is placed in front of the ball. The protruding upper door plate 5a corresponds to one door plate of a conventional winning device, and the lower door plate 5b
Since these are arranged in series, when the door is closed, the opening corresponding to the width of the door plate below can be closed.

Therefore, according to the present invention, as the door plate is substantially expanded, the input f.
It is possible to enlarge the opening 2 of the i-device, and it is possible to provide a winning device that opens wide when opened.

The opening of this winning device is wide open to allow the player to feel how easy it is for winning balls to fly in, and also to see how the valid balls that fly in through this opening move inside the frame. In particular, in the case of a device in which a plurality of passages 4 are formed inside the frame and the prize ball conditions are further changed depending on the selection of the passages, the game can be visually enjoyed even more. This is advantageous because it allows you to
