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 pachinko machine surface so that they stand parallel to each other or tilt in an inverted diagonal shape, as shown in the conventional example in Figure 7. After the front plate and the lower socket are provided, a guiding frame is formed at the rear of the board, and a scale-shaped actuating piece is swingably supported within the frame, and the movable wing piece is pivotably mounted. and said movable piece to operate in conjunction with each other, and based on a safe ball socket main body that can move the safe ball socket in two wide and narrow modes, directly below said operating piece forming a locking step on the lower surface. , with a slight gap, either the beak or the rear end of the front end is contactably and swingably supported directly below the pivot of the actuating piece, and the front end has a lower socket. A known safe ball socket is provided with a tongue-shaped ball receiving piece extending facing the operating piece, and when the operating piece moves in elevation, the beak locks onto the locking step to maintain the elevational state of the operating piece. The vessel is
Since the engagement relationship between the locking step on the back of the actuating piece and the front end beak of the lock plate is an extremely small angle engagement, the actuating piece is normally affected by the impact of the movable blade being struck on the board surface. , a flapping action occurs, which leads to the phenomenon of hitting the front end of the lock plate, which forces the lock plate in the forward rotational direction, often causing the lock plate to unexpectedly release its engagement even though the safe ball does not enter. I was worried that the plate would rotate forward.
Therefore, in the present invention, the locking mechanism has been improved in order to exhibit a strong locking effect against unexpected pressing of the lock plate against the actuating piece in the forward rotational direction.

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 substantially on the vertical axis x-line with the pivot part 8 of the actuating piece; Actuation piece 7
At the top dead center of the elevation angle due to the rearward rotation, the lock plate 10 is engaged and held in the elevation position.
This lock plate 10 is connected to the shaft support 8 of the actuating piece 7.
The beak part 15 of the front end 13 and the rear end part 14, which engage with the locking step part 12 formed in the front bottom part, are made to be able to come into contact with the corresponding bottom face of the upper operating piece 7. A leg portion 16 is extended below the front end, and a tongue-shaped ball receiving piece 17 is integrally molded from the front end of the leg, and the ball receiving piece enters into the inner space of the lower front socket portion 6 of the mounting board 2. I'm making it happen. Reference numeral 18 denotes a movement 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. The first embodiment is shown in FIGS. 1-4, and the second embodiment is shown in FIGS. 5-6.

To explain the first embodiment first, a protruding shaft 22 is provided on the slightly front side surface of the actuating piece 7 in front of the pivot portion 8.
In the lock plate 10 which is integrally provided and is provided directly below the actuating piece 7, the pivot support 11 is formed with a pivot support 11a on the vertical line x passing through the pivot support 8, as in the conventional example shown in FIG. , the leg part 16 supporting the tongue-shaped ball receiving piece 17 integrated in the lower front part is extended upwardly 23
A locking step 24 is cut out at the top of the locking step 24, and at the elevation top dead center position of the actuating piece 7, the locking step 24 engages with the protruding shaft 22 on the front side of the actuating piece 7 to maintain the elevational posture. do. Now, as shown in FIG. 2, the movable wing pieces 4,
4', when the safety ball enters from above, the rear end of the actuating piece 7 moves downward, and as a result,
When the rear end 14 of the lock plate 10 is pushed down and turned into an elevation position by the action of the safety ball, the movable wing pieces 4, 4' are tilted as shown in FIG. The protruding shaft 22 of the piece 7 engages with the protruding shaft 22, and as the tongue-shaped ball receiving piece 17 moves downward with the next safe ball, the locking stepped portion 24 rotates forward,
The meshing engagement with the protruding shaft 22 is released, and the actuating piece 7 operates horizontally by the weight of its head, and the movable wing piece 4, which stands up,
4' and returns to FIG.

Next, to explain the second embodiment, the operating piece 7 is integrally provided with a protruding shaft 22 on the side surface slightly in front of the pivot part 8, and is provided with protection to prevent the safe ball on one side from moving out before and after the pivot part 8. Although the wall portion may be left, the illustration shows a case where the wall portion is not left, and the rear half is cut off at 20
At the same time, the shaft support 11 of the lock plate 10 is provided near the front end 13 on the vertical axis A movable pin 1 that is integrally lifted up and formed like a tail, whose rear half enters the cutout 20 of the actuating piece, and on one side of the rear half is used to operate in conjunction with other back part mechanisms.
8 protrudes, and the other side forms an inclined surface 21 for discharging the safe balls rolling from the front to the side. If the protective wall portion is left on one side of the rear half of the operating piece 7, it may be integrally formed on the lock plate 10 side. The leg part 16 supporting the tongue-shaped ball receiving piece 17 integrated in the lower front part is extended upwardly 23, and a locking step part 24 is cut out at the top of the leg part 16, and the leg part 16 is cut out at the top dead center position of the actuating piece 7 in terms of elevation angle. The locking step portion 24 engages with the protruding shaft 22 on the front side surface of the actuating piece 7 to maintain the elevational attitude.
In this embodiment, the locking stepped portion 24 forms a plate cam portion 25 that continues behind it, and as the lock plate 10 rotates backward, the protruding shaft 22 is pushed upward by the cam. The operating piece 7 begins to escape and begins to rotate in elevation.

Now, when the movable wing pieces 4, 4' are in the upright state as shown in Fig. 5, the rear half of the actuating piece 7, which exposes the head between the downward facing portions, is cut off 20, so the rear part of the actuating piece 7 is cut off in the cut-off space. The rear end 14 of the lock plate 10 is connected and stationary in an upward direction, and the safe ball that enters from the upper part falls onto the actuating piece and rolls to the rear half, and the lock plate 1
The safe ball rides on the rear end 14 of the rising rear end at 0, and while moving the plate downward, the safe ball moves along its sloped surface 21.
The plate is discharged laterally along the upwardly extending portion 23 of the leg portion 16 as the projecting shaft 22 of the actuating piece 7 is gradually pushed by the plate cam portion 25 on the rear surface of the upper extending portion 23 of the leg portion 16. When the actuating piece rotates in elevation, the locking step 24 of the lock plate 10 and the protruding shaft 22 of the actuating piece 7 engage to maintain the elevation state. The movable wing pieces 4, 4' tilt 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 stopped. The state is released and the state shown in FIG. 5 is restored.

The present invention has the above-mentioned configuration, and due to the related operation of the actuating piece 7 and the lock plate 10, the actuating piece 7
In the safe ball socket main body 1, which can be fixed at the top dead center position of the elevation angle, the safe ball socket can be moved in two wide and narrow modes. 10 shaft supports 11a are provided, and a locking step 24 is provided in the upwardly extending portion 23 with a means for holding the elevation top dead center position, and the protruding shaft 2 of the actuating piece.
2, and the protruding shaft 22 of the actuating piece to which the plate cam part 25 is attached, so that the original function of the actuating piece 7 is not impaired at all. Instead, the locking step 24 of the lock plate 10 faces directly below the protruding shaft 22 of the actuating piece 7, which coincides with the swing locus. Therefore, since the angle of engagement between the operating piece 7 and the lock plate 10 in the conventional example is changed to a substantially right angle angle of engagement, the lock mechanism does not require the use of separate members such as magnetic force. Mechanically, a slight improvement in the structural members has produced a remarkable tensioning effect, and even when the movable blades 4 and 4', which tilt in an inverted C-shape on the board surface, are simply struck by a passing ball, the impact can be reduced. The worry of unexpected changes in the safe ball socket due to the influence of can be completely eliminated, and
This invention brings about great benefits, such as making it possible to make the whole structure more compact, thereby making it possible to obtain a large overhead space x' for the connecting gutter A that communicates with other mechanisms installed at the rear and lower part of the guide frame 9.
