Description

[Detailed description of the invention] The present invention relates to a safe ball socket for pachinko machines,
The purpose of this is to pivot 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 can be tilted from parallel standing up to an inverted H shape, as well as a front decoration. After providing the plate and the lower socket, a guide frame is formed at the rear of the board, and a scale-shaped actuating piece is swingably supported within the frame, so that the movable wing piece and the actuating piece can be operated in conjunction with each other. Based on the safe ball socket device main body which can change the safe ball socket into two wide and narrow modes, a slight gap is present directly below the actuating piece forming a locking step on the lower surface, Either the beak part of the front end part or the rear end part is pivotally supported so that one can contact and swing freely, and the front end part has a tongue-shaped ball receiving piece extending thereto facing the lower socket part, and an actuating piece. In a safe ball receptacle in which the beak locks into the locking step to maintain the elevational state of the actuating piece when the actuating piece moves in elevation, the actuating piece is protected on one side immediately after its pivot. The rear half is cut off leaving the wall part, and the rear half is lifted up from the pivot part of the lock plate in an inverted U-shape to enter the cut-off part of the actuating piece, thereby forming a safe ball that rolls from the front half of the actuating piece. The main feature is that the front half of the actuating piece is lifted up as the actuating piece rotates backward in response to the movement of the lock plate, and the elevation angle is maintained. As shown in Fig. 2, in the conventional device designed to rotate, the rear end of the actuating piece or lock plate hangs low, so a safety ball is connected directly below the rear end of the socket to interlock with other sockets. When setting up gutters,
Since it was not possible to obtain overhead space for the ball to pass through unless it was installed considerably lower, this was a factor that hindered compactness in the settings of various mechanisms, so we decided to change the operating piece and lock plate This invention has an inventive step that greatly contributes to making the back mechanism of a pachinko machine more compact, as by improving the related mechanism, the overhead space X of the connecting gutter at the same setting position can be greatly increased.

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 being integrally molded 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-like actuating piece 7 is swingably pivoted 8 in the space inside the frame. Guidance frame 9 as shown
The lock plate 10 is pivotally supported 11 with a slight gap just below the lever-shaped actuating piece 7 which is pivotally supported, and the lock plate 10 is pivoted at the top dead center in elevation due to rearward rotation of the actuating piece 7. Plate 10 is associated and maintains the elevation position. This lock plate 10 is
Only one of the beak portion 15 of the front end 13 and the rear end portion 14 that engages with the locking step portion 12 formed on the bottom surface in front of the shaft support 8 of the actuating piece 7 is connected to the corresponding bottom surface of the upper actuating piece 7. A leg portion 16 extends below the front end, and a tongue-shaped ball receiving piece 17 is integrally molded from the front end of the leg. The inner sky is about to be invaded. 1
Reference numeral 8 designates an interlocking pin that projects from below the guide frame 9 on one side of the rear end of the actuating piece 7.

The present invention is constructed as follows based on the above-mentioned known mechanism. That is, as shown in FIGS. 3 and 4, the rear half of the actuating piece 7 is cut off 20 immediately after the pivot portion 8, leaving the protective wall 19 on one side for preventing the safety ball from moving out, and the locking plate is removed. 1
0, the rear half 14' is integrally lifted up upwards like a bird's tail in relation to the front half 13' in relation to the front half 13', and the rear half is formed as a part of the actuating piece. An interlocking pin 18 is inserted into the cutout part 20, and an interlocking pin 18 is protruded from one side of the rear part to operate in conjunction with other back part mechanisms, and the other side is used to eject the safety ball rolling from the front to the side. An inclined surface 21 is formed. The protective wall portion 19 left on one side of the rear half of the operating piece 7 may be integrally formed on the lock plate 10 side, and the difference in construction does not change the gist of the present invention.

To explain its action, when the movable wing pieces 4, 4' are in the upright state as shown in Fig. 3, the rear half of the actuating piece 7, which exposes the head between the downwardly facing parts 20, is cut off. Lock plate 1 rises in space
The second half 14' of the lock plate 10 is connected and stationary, and the safe ball that enters from the top falls onto the actuating piece and rolls to the second half, causing the rear half 1 of the lock plate 10 to rise.
4', the safe ball is ejected while moving the plate downward, and the plate moves both while the front end beak 15 of the front half 13' touches the operating piece 7 which covers the head above the bottom surface of the operating piece 7. The elevation angle is rotated in relation to each other, and the bottom surface locking step portion 12 and the beak portion 15 engage with each other at the elevation angle top dead center of the actuating piece as shown in FIG. 4 to maintain the elevation angle state. Movable wing piece 4,
4' tilts to provide a wide ball socket, and then, as the tongue-shaped ball socket 17 is pressed downward by the safe ball that enters from the wide ball socket, the engagement is released and the third The state will return to the state shown in the figure.

The present invention is as described above, and the rear half 14' of the lock plate 10 formed in an inverted V-shape enters into the cutout space 20 of the actuating piece 7, and has the same effect as the rear half of the actuating piece. In comparison with the conventional example shown in FIG. 2, without impairing the original function of the actuating piece 7 at all, an interlocking gutter which is intended to be used for interlocking is set at the rear end of the lock plate 10 at the elevation angle and directly below it. The present invention has a great effect in that it is possible to obtain a head space X ₂ which is greatly increased from the head space X ₁ with respect to A. Furthermore, if an interlocking pin is provided protruding from one side of the lock plate 10, it can be operated in conjunction with other mechanisms while securing _the above-mentioned overhead space It is extremely practical as it allows effective use of a narrow space for the mechanism to be set. Note that the protective wall portion 1 left on one side of the rear half of the actuating piece 7 described above
9, the interlocking pin 18 may be provided protrudingly on one side of the wall portion 19. This is because the rear portion 14' of the lock plate 10 can be formed upwardly. The interlocking pin 18 has the effect of being able to protrude upward from itself.
