Description

[Detailed description of the invention] [Field of industrial application] The present invention has a pair of opening/closing wings that are rotatably supported on the front surface of a mounting plate, which can freely rise and tilt. A rotating body rotates by a ball passing between the pieces to control the upright and tilting of the opening/closing wing pieces; This invention relates to an improvement of a safe ball socket for a pachinko machine which is provided with a lever operating body that causes the body to rotate.

[Prior Art] Conventionally, in this type of safe ball receptacle, a magnetic body is provided in a lever actuating body, and a magnet is provided in a box frame portion facing the magnetic body at a non-acting position of the lever actuating body, A mechanism that prevents the lever operating body from moving inadvertently by the attraction action of the magnetic body has already been proposed and known in U.S. Pat. No. 60-194080 by the present applicant.

[Problems to be solved by the invention] However, this conventional safe ball receptacle prevents the lever operating body from moving accidentally due to the mutual attraction between the magnetic bodies. It was found that if the magnetic force is weak, it is not useful for preventing the lever actuating body from moving accidentally, and if the magnetic force is strong, the lever actuating body cannot swing, etc., making it unsuitable for practical use. It was devised in view of the above circumstances, and its purpose is to provide a safe ball socket for pachinko machines that can reliably prevent the lever actuator from moving accidentally without using a magnet. .

[Means for solving the problems] The structure of the present invention to achieve the above purpose is as follows:
This will be explained using FIGS. 1 to 4 corresponding to the embodiment.

In the present invention, a pair of opening/closing wings 3, 3 that can be freely raised and tilted are pivotally supported on the front surface of the mounting plate 1, and a passage between the opening/closing wings 3, 3 is provided in a box frame 8 on the back side of the mounting plate 1. A rotating body 12 rotates with a ball to control the upright and tilting of the opening/closing wings 3, 3, and a rotating body 12 that swings in response to a ball entering the interior through an introduction opening 10 formed on the rear upper surface of the box frame 8. In a safe ball socket including a lever operating body 17 that causes rotation of the rotating body 12, a ball contact portion 27 facing the introduction opening 10 of the box frame 8 is provided above the lever operating body 17; 1
An engaging portion 26 that contacts and engages with 7 to restrain its swinging.
The movable restraint member 24 provided with the movable restraint member 24 is pivotally mounted.

[Function] Normally, the engaging portion 26 of the movable restraint member 24 contacts and engages the lever operating body 17.

Further, a spherical outflow opening 11 is formed in one side wall.

Reference numeral 12 denotes a rotating body that corresponds to the upper part of the ball inlet 2 and is freely rotatably supported on a horizontal shaft 13 extending within the box frame 8. This rotating body 12 is arranged at equal intervals from the center as shown in FIG. Three ball engagement pieces 14a to 14c are provided which protrude in the radial direction, and engagement walls 15, 15 are provided at part of both ends. Each ball engaging piece 14a
~14c are always placed in a position where one of them is in contact with the ball entering the ball inlet 2 through the opening/closing wings 3, 3. Further, when the engaging walls 15, 15 are engaged with the inner surfaces of the protrusions 5, 5 of the opening/closing wings 3, 3, the engaging walls 15, 15 hold the opening/closing wings 3, 3 in the upright position shown by solid lines in FIG. 16
The upper end is fixed to the back surface of the mounting plate 1, and the free end is connected from the rear of the rotating body 12 to one of the ball engaging pieces 14a to 1.
This is a leaf spring that is pressed against the rotating body 4c, and prevents the rotating body 12 from moving inadvertently or excessively.

Reference numeral 17 denotes a lever actuating body which is supported in a freely swinging manner on a horizontal shaft 18 extending across the box frame 8 at the rear part of the rotating body 12, and is located below the horizontal shaft 18 and at the rear as shown in FIG. A ball receiving part 20 is provided in a protruding manner to rotate the rotating body 12 by engaging the ball engaging piece 14c that stops at the ball engaging piece 14c. will be established.
In addition, a groove-shaped engagement recess 21 is located above the horizontal shaft 18.
will be established. The upper surface of the ball receiving part 20 has an outflow opening 11
It is formed as an inclined surface toward . A weight 22 is attached to the lever operating body 17 below the horizontal shaft 18, so that the lever actuating body 17 is always rotatably held in a substantially horizontal position shown by the solid line in FIG. 23 is a stopper formed on the box frame 8.

Reference numeral 24 denotes a movable restraint member rotatably supported on a horizontal shaft 25 extending over the box frame 8 at the upper part of the lever actuating body 17, and as shown in FIG.
The engagement recess 21 of the lever operating body 17 is located below the lever operating body 17.
An engaging portion 26 that engages with the horizontal shaft 25 is provided in a hanging shape.
A ball contact portion 27 facing the introduction opening 10 of the box frame 8 is formed in a protruding shape at the rear of the box frame 8. The movable restraint member 24 is provided with a weight 28 below the horizontal shaft 25, and is always urged to rotate downward, and as shown in FIG. This prevents the lever operating body 17 from moving inadvertently.

The rotary body 21 has a rear end portion cut out from the ball engaging pieces 14a, 14b so that the feed pawl 19 of the lever actuating body 17
A spacing section 29 is provided to avoid contact with. Further, each of the engaging surfaces of the engaging portion 26 of the movable restraint member 24 and the engaging recess 21 of the lever actuating body 17 is formed as a circular arc surface centered on the horizontal axis 25.

To explain the operation of this embodiment, when the opening/closing wings 3, 3 are standing up as shown by the solid lines in FIGS. It is guided by the guide bottom piece 7 and comes into contact with the ball engaging piece 14a of the rotating body 12, and flows out into the ball passage 9 while rotating the rotating body 12. The pressing action of the leaf spring 16 prevents the rotating body 12 from over-rotating, and each time the ball enters between the opening and closing blades 3, 3, the rotating body 12 is rotated by the angle between the ball engagement pieces 14a to 14c ( (120 degrees in this embodiment) rotation is correctly regulated. On the other hand, the opening/closing blades 3, 3 are moved to the engagement wall 1 by the rotation of the rotating body 12.
5 and 15 move rearward and are disengaged from the protrusions 5 and 5, so that they tilt under their own weight as shown by the chain lines in FIG. Thereafter, in the same way, each time the ball enters between the opening/closing wings 3, 3, the rotating body 12 rotates, and the protrusions 5, 5 of the opening/closing wings 3, 3 are engaged with the engaging walls 15, 15 of the rotating body 12. It stands up, and when the engagement is released, the tilting motion occurs without any disturbance.

Therefore, in the present invention, as shown in FIG.
It prevents delusional movements. When a ball enters from the introduction opening 10 of the box frame 8 in this state, it contacts the ball contact piece 27 as shown by the solid line in FIG. Guided by 20. This rotation of the movable restraining member 24 causes the engaging portion 26 to move into the engaging recess 2 of the lever actuating body 17.
1, the lever operating body 17 comes off while sliding on the arc surface.
release the restraints. Therefore, the ball causes the lever actuating body 17 to swing as shown by the chain line in FIG. Rotate and tilt the opening/closing blades 3, 3. Then, when the ball flows outward, the lever operating body 17 and the movable restraint member 24 are returned to the state shown in FIG. 4 by the action of the weights 22 and 28, respectively. It should be noted that when the opening/closing blades 3, 3 are tilted, the feed pawl 19 corresponds to the gap 29, so that it passes through the gap 29 without rotating the rotating body 12 and only reciprocates.

[Effects of the Invention] As described above, according to the present invention, the installation of the movable restraint member completely prevents the lever operating body from moving accidentally due to external impact. Since the lever actuating body is directly restrained and held by the engagement of the movable restraint member, it is more stable and prevents accidental movement to a much higher degree than when using the attraction action of a magnet as in the past. Unique effects such as being able to exhibit effects can be achieved.
