Description

[Detailed description of the invention] The present invention relates to a safe ball socket for pachinko machines,
The purpose of this is to raise and lower a pair of left and right movable blades on both sides of the opening of the mounting board that is nailed to the surface of the pachinko machine so that they stand parallel to each other or tilt in an inverted diagonal shape, as shown in the conventional example in Figure 5. A guide frame is formed at the rear of the board after the front plate and the lower socket are provided, and a scale-like actuating piece is swingably supported within the frame, and the movable wing piece and Directly below the actuating piece, the actuating piece is formed to operate in conjunction with the actuating piece, and a locking step is formed on the lower surface based on the safe ball receptacle main body that changes the safe ball receptacle in two wide and narrow modes. Either the beak portion or the rear end portion of the front end portion is contactably and swingably supported directly below the pivot axis of the actuating piece, with a gap formed therebetween, and the front end portion faces the lower socket portion. A known safe ball socket has an extended tongue-shaped ball socket, and the beak locks onto the locking step when the operating piece moves in elevation to maintain the elevational state of the operating piece. The interlocking pin protruding from one side of the rear end of the actuating piece is formed to operate in conjunction with another back interlocking mechanism,
As shown in Utility Model Publication No. 6476 of 1975, the rear end of the actuating piece can be changed from a narrow ball socket to a wide ball socket even though the winning ball does not fit into the front ball socket using related parts. The operating principle is the same as that of the fluctuating operating mechanism, and the actuation is performed in conjunction with the interlocking pin, which is a protruding member, without directly touching the actuating piece, so although it is possible to actively push down the rear end of the actuating piece. In principle, it is impossible to pull up the ball, so it was impossible to consciously change the wide ball socket even though the winning ball would not fit into the narrow ball socket. Therefore, the present invention locks the beak of the lock plate to the bottom locking step when the actuating piece moves in elevation in the conventional device to maintain the elevation state, and also locks the beak of the lock plate on the bottom locking step when the actuating piece moves in elevation, and also locks the beak of the locking plate in the elevation angle state when the actuating piece moves in elevation. It is made to be able to double move up and down, and in relation to this movement, the ball socket can be consciously moved in two ways, wide and narrow.

Embodiments of the present invention will be described with reference to the attached drawings. First, a conventional example will be outlined. Reference numeral 1 is a conventionally known safe ball socket device body, and an opening in a mounting board 2 that is nailed to the surface of a pachinko machine. A pair of left and right movable wing pieces 4, 4' are pivoted on the lower side of both sides of the part 3 so as to be able to stand up in parallel or tilt in an inverted C shape, and a front decorative plate 5 that supports the movable wing pieces is attached to a lower socket. After integrally molding with the part 6, it is fixed to the mounting board 2, and a guide frame 9 is formed at the rear of the board, and a scale-shaped actuating piece 7 is swingably pivoted 8 in the air inside the frame. A lock plate 10 is swingably supported with a slight gap just below the lever-shaped actuating piece 7 which is pivotally supported at 9, and is pivotally supported 11 approximately on the vertical axis of the pivot part 8 of the actuating piece. When the piece 7 rotates backward, the lock plate 10 engages with the plate 10 at the top dead center of the elevation angle to maintain the elevation position. This lock plate 10 has a beak 15 of the front end 13 and a rear end 14 that engage with a locking step 12 formed in a notch on the bottom surface in front of the shaft support 8 of the actuating piece 7. The corresponding bottom surface of the actuating piece 7 faces so that it can be contacted, and the leg portion 16 extends below the front end.
A tongue-shaped ball receiving piece 17 is integrally molded from the front end of the leg, and the ball receiving piece faces the inside space of the lower socket part 6 on the front surface of the mounting board 2 in a state of intrusion. Reference numeral 18 designates an interlocking pin that projects from below the guide frame 9 on one side of the protective wall portion 19 at the rear end of the actuating piece 7.

The present invention utilizes the lock mechanism and is constructed as follows in order to enable the operating piece to move vertically and backward in relation to the vertical and backward movement of the back interlocking mechanism. Protective wall portion 19 integrally molded on one side of the actuating piece 7
The rear end plate part 20 is exposed and molded by removing the rear part.
Reference numeral 21 is a flow guide piece integrally formed on the rear end, which functions to change the direction of winning balls rolling from the front to the rear on the upper surface of the operating piece at right angles to the discharge port on one side. Reference numeral 12 denotes a locking step portion formed in the bottom in front of the pivot portion 8. On the other hand, the lock plate 10 has the pivot portion 1 on the vertical axis x-line passing through the pivot portion 8 of the actuating piece 7.
As shown in FIG. 4, a beak part 15 of the front part 13 is integrally formed with a leg part 16 having a tongue-shaped ball receiving piece 17 projecting from the lower end thereof, and a beak part 15 of the front part 13 has a beak part 15 formed on one side of the rear end of the rear part 14, as shown in FIG. The arm portion 22 extends rearward and upward, and a minus character-shaped cutout recess 23 is formed at the base of the arm portion, and an interlocking pin 18 is integrally protruded from the outside of the upper end of the arm portion 22. As shown in FIG. 2, when assembling these two, the rear end plate 20 of the actuating piece 7 disposed at the upper stage is inserted into the minus-shaped notch 23 in the arm 22 of the lock plate 10. They mesh and engage in a slidable manner in the lateral direction.

The present invention has the above-mentioned configuration, and when the conventional operating piece 7 with a locking mechanism is constructed so that the interlocking pin 18 protruding from the rear end is operated in conjunction with the back interlocking related member, the socket main body 1 is in an upright position. Movable wing piece 4,
Although the winning ball does not enter the ball socket, the rear end of the actuating piece 7 is pushed down to tilt the movable wing pieces 4, 4' to create a wide ball socket. Although it is possible to change the opening to the opening, it is impossible to change the opening to a wide ball socket regardless of the winning ball as described above. However, in the present invention, the arm part 22 of the lock plate 10 is By fitting the push-down and pull-up return movement related member 24 to the interlocking pin 18, the movable wing pieces 4,
4' is tilted and then when the lock plate 10 is pulled up, the rear end plate portion 20 of the actuating piece 7 is engaged with the minus letter-shaped notch recess 23 of the arm portion 22 of the lock plate 10. The movable blades 4, 4', which are tilted by being forcibly operated in conjunction with the rotation, can be moved upright and can be easily moved even in a narrow ball socket, which is different from the conventional ball socket with a locking mechanism. The operating piece 7 and the lock plate 10 have been slightly improved in this way, and in response to the up and down movement of the interlocking pin 18, the ball socket can be freely operated in two ways, regardless of the winning ball. This is an excellent invention, as it can be made as compact as conventional products, and does not interfere with conventional functions.
