Description

[Detailed explanation of the invention] This invention uses a ball that fits between a pair of opening/closing pieces provided on the front of the mounting plate to raise the opening/closing pieces or tilt them in an inverted figure eight shape to change the possibility of winning a prize. Regarding the variable safe ball socket, to be more specific, it is a variable safe ball socket that can cause the opening/closing piece to tilt even when balls enter other winning holes and flow out onto the back side of the game board. This relates to the opening device in the device.

In pachinko machines in which a variable safe ball socket is attached to the game board, an interlocking member that is activated by the weight of balls that enter from other winning holes has been installed on the back of the game board, and the vertical operating rod of this is connected to the safe ball socket. The opening of the guide box on the back side of the socket allows the rear end of the swinging rod to be pushed upward from the top of the opening, so that even if a ball enters another winning opening, the opening/closing piece will tilt. In order to increase the interest of the game by giving an advantage to the player. However, in this case, there is a drawback that the tip of the operating rod obstructs the flow of balls in the guide box, and the lower end of the vertical operating rod faces into the guide box, so only safe ball receivers are used. This has the disadvantage that it gets in the way when removed from the game board, and that it is difficult to assemble and repair because the removal and installation must be done at the same time as the interlocking members.

The present invention aims to solve the above-mentioned drawbacks, and includes forming a notch in the side wall opposite to the side wall in which the outflow opening of the guide box is provided, and an operating projection projecting outward from the notch at the rear of the swinging rod. By providing a piece so that balls entering other winning openings act on the actuating protrusion, the opening/closing piece can be easily tilted and the flow of balls entering the guide box can be obstructed. This is designed to ensure smooth operation by avoiding the conventional drawbacks.

An embodiment of the present invention will be described below with reference to the drawings. Reference numeral 1 denotes a mounting plate, on both sides of the front of which a pair of opening/closing pieces 2, 2 are supported by shafts 3, 3 so as to be freely erected in parallel and tilted in an inverted eight shape. , both sides and the front side below the axis of the opening/closing pieces 2, 2 are covered by a cover member 4. Reference numeral 5 denotes a guide box fixed to the mounting plate 1 so as to cover the rear part of the mounting plate 1, and a swinging rod 7 is attached to a horizontal shaft 6 extending inside the guide box, and a swinging rod 7 projects downward from the tip thereof. A ball stopper piece 8 is provided. 9 is the swinging rod 7
This is an outflow opening formed in one side wall 10 of the guide box 5 corresponding to the rear end, and in this embodiment, it is shown as being formed in the right side wall of the guide box 5 in FIG. It can also be formed.

In the variable safe ball receptacle in this embodiment, when a ball B enters between the opening and closing pieces 2, which are tilted in an inverted eight shape, as shown by the chain line in FIG. As shown by the solid line in FIG. 5, the ball stopper piece 8 at the tip of the swinging rod 7 once prevents the outflow, and the opening/closing pieces 2 are held in the upright position as shown by the solid line in FIG. In this state, when a ball enters the guide box from the upper opening of the guide box 5, the weight of the ball lowers the rear end of the swinging rod 7 as shown by the chain line in Figure 5, and at the same time flips up the tip to release the ball B. The opening/closing pieces 2, 2 are caused to tilt, and the balls flow out from the outflow opening 9 of the guide box 5.

FIG. 3 shows one mode of using the variable safe ball socket of the present invention in conjunction with other winning holes. That is, 15 is a board on which interlocking members for supporting the ball commutation rod 16 and the operating rod 17 on fulcrum shafts 18 and 19, respectively, are attached, and is associated with the two variable safe ball sockets a ₁ and a ₂ . Then, it is fixed to the back side of the game board 12. Reference numeral 20 denotes a weight such that the center of gravity of the ball commutation rod 16 is normally placed on one side; 21 is a blocking piece provided integrally with the base plate 15 at the end of the ball commutation rod 16; Ball diversion rod 16
is able to maintain the angle necessary for commutation of the ball while still preventing its distal end from rising upwards. Reference numeral 22 is a continuous rod provided integrally with the ball commutation rod 16, and its tip bent portion 23 is located in contact with the lower surface of one end of the operating rod 17. Further, the operating rod 17 is configured to be longer than the other side, calculated from the fulcrum shaft 19, so that the center of gravity is on one side, and therefore, the tip of one side is always placed on the bent portion 23. The tip of the other end is integrated with the swinging rod 7 of the variable safe ball socket _A1 , and the guide box 5
It is arranged so as to be able to come into contact with an actuating protrusion 14 that protrudes outward from a notch 13 formed in the side wall 11 on the opposite side from which the outflow opening 9 is provided. Note that 24 is a transfer port for receiving balls flowing out from other winning ports provided on the front surface of the game board 12 and transferring them to the upper surface of the ball transfer rod 16.

Now, the opening and closing pieces 2 of the variable safe ball sockets a ₁ and a ₂ ,
When 2 is standing up, balls that enter from other winning holes
B' is diverted from the diverting outlet 24 onto the ball diverting rod 16,
The ball commutation rod 16 lowers its tip as shown by the chain line in Figure 3 against the weight of the weight 20, and drops the ball B' into the interior through the opening on the top of the guide box 5 of the floating safe ball socket _a2 . let me,
The weight of the ball moves the rear end of the swinging rod 7 downward to tilt the opening/closing pieces 2, 2. At the same time as the above operation is carried out, one end of the operating rod 17 is moved upward as shown by the chain line in FIG. ball socket
By pushing the operating protrusion 14 of a ₁ , the rear end of the swinging rod 7 is moved downward, and the opening/closing pieces 2, 2 are tilted.

As is clear from the above explanation, according to the present invention,
In a variable safe ball socket having a structure in which when the rear end of the swinging rod 7 is moved downward, the opening/closing pieces 2, 2 can be caused to tilt in relation to this, the swinging rod 7 is mounted on a shaft. A notch 13 is formed in the side wall 11 on the opposite side of the side wall 10 in which the outflow opening 9 of the guide box 5 is provided, and the notch 13 is formed in the rear part of the shaft 6 of the swinging rod 7.
An operating protrusion 14 is provided that protrudes outward from the guide box, so that the weight of the balls that enter other prize openings on the outside of the guide box and flow out onto the back side of the game board can be applied to the rear end of the swinging rod. It is. Therefore, it is possible to eliminate the disadvantage of obstructing the flow of balls and the inconvenience during installation and removal, which occur when the vertical operating rod is exposed inside the guide box as in the prior art. In addition, since the ball can flow out from the opposite side of the actuating protrusion, the length behind the axis of the swinging rod required to tilt the swinging rod due to the weight of the ball is calculated as the total depth inside the guide box. Since the dimensions can be secured, there is also the advantage that the existing space can be used for sufficient assembly without fear of running out of space on the back of the game board by enlarging the guide box.
