A composite safe ball socket is known in which an actuating member for controlling the upright and tilting of each pair of opening/closing blades is pivotally attached.

This composite safe ball receiver can bring about various changes in the manner of winning, and is useful for increasing the interest of the game.

[Problems to be solved by the invention] By the way, this conventional composite safe ball socket has the following problems:
The upper and lower opening/closing blade pairs and the actuating member are assembled and integrated onto a single mounting board.

For this reason, there was a drawback that the upper and lower parts could not be separated and used as a single safe ball socket. In addition, it is very difficult and time-consuming to assemble the two sets of components of the safe ball receptacle into one mounting plate, resulting in high manufacturing costs.

Therefore, the purpose of the present invention is to provide a double fluctuating safe ball socket for a pachinko machine that can be manufactured easily and inexpensively by eliminating the above-mentioned conventional problems, and can be separated and used alone. be.

[Means for solving the problems] Means for solving the above problems will be explained using FIGS. 1 to 6, which correspond to embodiments.

Reference numeral 8 is a box frame connected to the back surface of the mounting plate 1 at the rear of the ball inlet 2, and rotatably supports a rotating body 10a, which is an operating member 10, on a horizontal shaft 9 extending inside the box frame. As shown in FIG. 5, the rotating body 10a is provided with four ball engagement pieces 11 that protrude in the radial direction at equal intervals from the center, and engagement walls 12 are provided between the ball engagement pieces 11 at both ends. They are formed alternately. One of the ball engaging pieces 11 is always connected to the opening/closing wing pieces 3, 3.
It is placed in a position where it contacts the ball that enters the ball inlet 2 through the gap. Further, when the engagement wall 12 is in an engaged position with the inner surface of the projections 5, 5 of the opening/closing wings 3, 3, the engaging walls 12 hold the opening/closing wings 3, 3 in the upright position shown by solid lines in FIG.

In addition, 13 is pivotally supported on a horizontal shaft 14 in the box frame 8 to engage the ball in order to prevent the rotating body 10a from increasing one predetermined rotation angle (360°/number of ball engagement pieces 11). A rotation regulating piece 15 is engaged from above between the joint pieces 11, and a lever 15 swings by a ball guided to an opening 16 on the upper surface of the rear end of the box frame 8 to rotate the rotating body 10a by a predetermined angle. It is a working body.

These variable-safe ball sockets a ₁ and a ₂ are designed to prevent a ball from entering the rotating body when the opening and closing blades 3 and 3 are upright as shown by the solid line in Figure 3. 1
It contacts the ball engaging piece 11 of 0a and falls downward while rotating the rotating body 10a. At this time, the rotation regulating piece 13 in contact with the ball engaging piece 11 causes the rotating body to
0a is prevented from over-rotating, and as a result, each time the ball enters between the opening and closing blades 3, 3, the rotating body 1
0a is correctly rotated by the angle between the ball engaging pieces 11. The opening/closing wings 3, 3 repeatedly perform an operation of standing up when the protrusions 5, 5 thereof are engaged with the engagement wall 12 of the rotating body 10a, and tilting when the engagement is released. .

Further, when the opening/closing wings 3, 3 are upright, when the ball is guided from the opening 16 of the box frame 8 to the upper surface of the lever actuating body 15, the lever actuating body 15 is rotated by the weight of the ball, and the tip thereof is rotated by the weight of the ball. spring up. Then, it comes into contact with the ball engagement piece 11 of the rotating body 10a, rotates the rotating body 10a, and tilts the opening/closing blades 3, 3.

In order to prevent the overlapped portions of the two variable safe ball sockets a ₁ and a ₂ from shifting, the lower part of one mounting plate 1 is made to protrude, and the upper part of the other mounting plate 1 is recessed. In addition, the upper variable safe ball socket a ₁ has a guide part 17 that guides the ball flowing out from the ball inlet 2 to the opening 16 of the box frame 8 to the lower safe ball socket a ₂ at the rear of the mounting plate 1. A screw insertion hole 19 is formed in the rear plate 18 of the box frame 8. Also,
The lower variable safe ball socket _a2 has a fitting protrusion 20 on the rear plate 18 of the box frame 8, and a screw insertion hole 21 in the center.
