Description

[Detailed explanation of the idea] The present invention relates to a safe ball socket for a pachinko machine.

Conventionally, the safe ball receptacle installed on the game board in a pachinko machine simply guides the safe ball to the safe ball detection means installed on the back of the game board, and releases the prize ball into the ball receptacle on the front of the game board. Along with the introduction of the safe ball, the so-called tulip was designed to change the inflow range of the batted ball into the safe ball inflow hole using, for example, a pair of movable blades that stood parallel and could tilt in an inverted eight shape. There are many things that make the game more interesting.

Conventionally, when forming the above-mentioned safe ball socket, the first
As shown in Figures A and B, first, a small hole 2 that slopes downward on the back side of the game board 1 made of plywood or the like is drilled using a drill 3 or the like, and then a safe ball socket is drilled. The hole 4 has a size corresponding to that of the small hole 2.
A through hole 5 is formed by leaving the lower part of the hole 5, and a safe ball socket 11 is formed corresponding to the through hole 5, for example, as shown in FIG. 1C. The mounting plate 13 has a safe ball inflow path 16 formed to surround the through hole 5, and the safe ball inflow path 1 is provided on the front side of the safe ball inflow path 16.
6, and when a safe ball is received by the safe ball receiving gutter 17, the through hole 5 and the mounting The ball passes through the safe ball inflow path 16 of the plate 13 and is led out to the back side of the game board 1.

However, the safe ball is inserted into the game board 1 from the above-mentioned through hole 5.
When guiding the safe ball to the back side, the safe ball will be caught on the lower end of the inner circumferential surface of the through hole 5 at the time it is led out from the safe ball receiving gutter 17, and if the through hole 5 is not sufficiently finished, the safe ball will be lost. However, even if precision finishing is performed, the drilled surface will become uneven due to the adhesion of dust and deformation of the plywood, preventing the safe ball from falling. It has the disadvantage of causing troubles such as a delay in the outflow of the prize ball, or a failure of the safe ball to fall and no outflow of the prize ball. After that, a hole 4 of a predetermined size is drilled and a through hole 5 is formed.
Therefore, it is necessary to drill two holes, which has disadvantages such as being relatively troublesome.

In addition, if the guide member is provided in an inclined state from the lower side of the safe ball socket gutter 17, a small hole 2 that slopes must be similarly drilled in the game board, and if this small hole 2 that slopes is not formed, A hollow portion corresponding to the inclination of the guide member is formed below the guide member, making it impossible to install the guide member of the safe ball socket 11 securely and with a sense of stability, and also causing vibration noise etc. due to the presence of the hollow portion. Furthermore, when the upper end of the guide member is formed in an inclined state and the lower end is formed in a horizontal state, the thickness becomes thicker.
This has disadvantages of increased material cost and weight.

The purpose of this invention is to prevent the safe ball from getting caught on the lower surface of the hole drilled in the game board, to quickly guide the safe ball to the back of the game board, and to prevent prize balls from flowing out. A safe ball holder for a pachinko machine that eliminates the risk of delays or spillage of prize balls, has a lightweight game board, makes it easy to drill through holes, allows for easy and reliable installation work, and is extremely economical. This will become clear from the detailed description below with reference to the drawings.

FIGS. 2A and 2B show a first embodiment of a safe ball socket for a pachinko machine according to the present invention, and this safe ball socket 41 has a through hole formed at a predetermined position on the game board 1. A mounting plate 43 of a safe ball socket 41 is fixed to the game board 1 with screws 15 through mounting holes 44 formed on both sides of the board 12 so as to surround the front side of the board 1. Unlike the conventional through hole 5, the hole 5 does not have a downwardly sloping portion, and is formed to extend horizontally in the front-rear direction of the game board 1.

The safe ball socket 41 has a safe ball inflow path 45 formed near the center of the mounting plate 43, and a safe ball socket gutter 42 so as to cover the lower part of this safe ball inflow path 45.
are integrally formed.

A guide member 46 extending toward the back side of the game board 1 is integrally formed in this safe ball socket gutter 42.
The safe ball received in step 2 is guided to the back side of the game board 1.

The lower end of the socket gutter 42 and the lower end of the guide member 46 on the side in contact with the lower end of the through hole 12 of the game board 1 are formed in a horizontal state to fit into the through hole 12 extending in the horizontal direction of the game board 1. At the same time, the socket gutter 42
A rising piece 47 extending in the front-rear direction is integrally formed at a position where the safe ball rolls between the guide member 46 and the guide member 46 . The upper end of this rising piece 47 is the game board 1
It is formed to be inclined downward toward the back side, that is, toward the rear. In this example, 1
Pairs of rising pieces 47 are provided at appropriate intervals.

Therefore, a pair of upright pieces 47 integrally formed on the socket gutter 42 and the guide member 46 serve as guide rails that tilt downward on the back surface of the game board 1 to move the safe ball received in the socket gutter 42. Therefore, the safe ball can be quickly guided to the back side of the game board 1. Moreover, the dust and the like attached to the safe ball fall between the pair of rising pieces 47, and the dust and the like are difficult to adhere to the upper surface of the rising piece 47, so that there is no risk of obstructing the fall of the safe ball.

In this embodiment, a case has been described in which one pair of rising pieces 47 is formed, but one or more pairs may be formed, and one pair of rising pieces 47 may be formed.
The interval between the guide members 7 and 7 may be such that it can receive the safe balls, and even if one guide member is formed near the center of the guide member 46, one side wall and the rising piece 47 may be formed.
It is sufficient that the safe ball is supported between the ball and the ball.

Further, FIGS. 3A and 3B schematically show a second embodiment of the present invention, and the safe ball socket 61 of this second embodiment has a different structure when fixed to the front surface of the game board 1. This safe ball socket 61 is equipped with a guide member 66 having a rising piece 67, and a mounting plate 6 formed on both sides of the socket gutter 62.
3, by utilizing the thickness of the socket gutter 62, a height corresponding to the thickness of the socket gutter 62 is integrally formed with the socket gutter 62 on both outsides of the socket gutter 62. A boss 65 is formed, and a nail hole 64 is formed in the center of this boss 65. Therefore, compared to the mounting plate 63 itself having nail holes formed therein, it has much greater strength and can drastically reduce the risk of the safe ball socket 61 being damaged.

According to the present invention, since it is only necessary to drill a horizontally extending hole in the game board, the hole drilling work is simple and work efficiency can be improved, and the upper end of the rising piece faces backward. Since it is tilted, there is no risk that the safe ball will get caught in the hole in the game board, and therefore the prize ball will flow out quickly, and the problem of the prize ball not flowing out can be prevented, and it is safe. A pachinko machine in which the ball socket can be mounted stably and reliably, is lighter and significantly more economical than the one in which the guide member with a sloped surface is made of bare material, and can fully satisfy the interests of players. This allows you to obtain a safe ball socket for the machine.

The above description merely shows one embodiment of the present invention, and it will be obvious that various modifications and changes can be made without departing from the spirit of the present invention.
