Description

[Detailed description of the invention] The present invention relates to a safe ball socket for pachinko machines,
The mechanism for this is that a pair of left and right movable wings are pivoted on both sides of the opening in the front of the mounting board to the pachinko machine surface so that they can stand up in parallel or tilt in an inverted C shape, and a guide frame formed on the rear surface of the mounting board has a balance-shaped pair of movable wings. In a conventionally known safe ball socket device, an operating piece is swingably supported, and the operating piece operates in conjunction with the movable blade to move the safe ball socket in two modes, wide and narrow. Then, when some external force is applied to the operating member of the movable wing piece or the balance-shaped actuating piece, such as contact with a passing ball or vibration of the board surface, the actuating piece unexpectedly operates, and the safe ball socket does not operate unexpectedly. The purpose is to mechanically lock the actuating piece to ensure the opening/closing operation of the safe ball socket body.

Embodiments of the present invention will be described with reference to the accompanying drawings. Reference numeral 1 is a conventionally known safe ball socket device body, and there are two pairs of left and right holes located below both sides of an opening 3 of a mounting board 2 that is nailed to the surface of a pachinko machine. The movable wing pieces 4, 4' are pivoted so that they can stand up in parallel or tilt in an inverted C shape, and the front decorative plate 5 that supports the movable wing pieces is integrally molded with the lower socket part 6. , 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 space within the frame. It was constructed as follows using a known mechanism. That is, as shown in FIG. 2, there is a slight gap just below the lever-shaped actuating piece 7 that is pivotally supported in the guide frame 9, and the lock plate 10 is pivotably supported 11 so that the actuating piece 7 can rotate backward. At the top dead center of the elevation angle, the lock plate 10 engages and maintains the elevation attitude. 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 cut out in the front surface of the shaft support 8 of the 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, and the ball receiving piece is attached to the mounting board 2.
The interior space of the front lower socket part 6 is exposed to the intrusion state. Reference numeral 18 indicates a guide frame 9 on one side of the rear end of the actuating piece 7.
It is an interlocking pin that protrudes from below. Note that the interlocking pin 18 may be provided protruding from one side of the rear end portion 14 of the lock plate 10 instead of protruding from the rear end of the actuating piece 7. The related operating members of the movable blades 4, 4' and the operating piece 7 in the safe ball socket main body 1 utilize a conventionally known mechanism as described above, and in the illustrated embodiment of the present invention, the movable blades 4 and 4' have their centers of gravity in the outward direction and normally tilt in an inverted C shape, with a stepped portion 19 provided on the corresponding surface of each blade, and a step portion 19 provided on the rear end of the flat portion from the lower side to the lower end slightly in the corresponding direction. an operating piece 7 which is integrally molded with a protrusion 20 for preventing a batted ball from escaping backwards and which protrudes from the outside; The movable wing pieces 4,
4' is maintained in the upright position. When the movable wing pieces 4, 4' are in the upright state, the narrow-mouth safe ball socket 22 is connected to the entry path regulating device 2 as shown in the perspective view of FIG. 1 and the sectional view of FIG.
3. That is, a direction regulating tongue piece 24 that tilts obliquely backward is integrally molded in the center of the U-shaped leg part 25, and the base end of the tongue piece 24 is engaged with the top of the front plate 5 to cut the upper surface of the leg part 25. A stepped part 26 is formed by fitting into the upper edge of the opening 3 of the mounting board 2 from below, and the safe ball that enters the ball receiving opening 22 hits the direction regulating tongue 24 that tilts backward, and the opening 3 and falls into the rear part of the actuating piece 7.
The rear end of the actuating piece 7 is pushed down, and as it rotates backward, the heavy front head 21 rises, and the movable wing pieces 4, 4' tilt in an inverted C-shape as the obstacles intervening in their corresponding lower parts disappear. , the aspect of the socket is changed to a wide-mouth safe ball socket 27.

Next, to explain the operation of the present invention, the movable wing pieces 4,
4' is upright, and when the safe ball enters the narrow safe ball socket 22, it hits the direction regulating tongue piece 24 of the transfer path regulating device 23 and rotates the operating piece 7 backward. At this time, after pressing down the rear end 14 of the lock plate 10 where the lower surface of the rear end of the operating piece faces directly below and operating the beak 15 of the front end 13 upward, the safe ball moves out and The heavy actuating piece 7 of 21 has its locking step 1
2 engages with the beak portion 15, and the state in which the downward movement of the forehead 21 is prevented is maintained. The movable blades 4, 4' which tilt in an inverted C-shape in relation to the backward rotation of the actuating piece 7 form a wide-mouthed safe ball socket, and the safe ball that enters from the socket is inserted into the movable blades 4, 4'. Flows into the center of the wing, spreads out the lower parts of both wings 4, 4', falls into the lower socket 6, rides on the tongue-shaped ball socket 17 facing the interior of the socket as shown in Figure 3, and locks. The plate 10 has a beak 1 that engages with the locking step 12 of the actuating piece 7.
As the engagement of the actuating piece 5 is released and the front end 13 is independently rotated forward, that is, the front end 13 is lowered, the rear end 14 pushes up the rear end of the actuating piece 7 and provides forward rotational force, and the front head 21 is formed to be heavy. If so, the front end moves downward under its own weight, changing from the state shown in FIG. 3 to the state shown in FIG. 2, causing the movable wing pieces 4, 4' to rise, and the safe ball socket also narrows accordingly. However, if the safe ball enters the narrow-mouth safe ball socket 22 even when the movable wing pieces 4, 4' are in the tilted state due to the action of the entry path restrictor 23, the swinging of the actuating piece 7 whose elevation angle is fixed The ball suddenly falls along the sloped upper surface without applying any pressure, and is guided to the next prize discharging process as a suspended safe ball without giving any action to the operating mechanism, that is, without narrowing the wide-mouthed safe ball receptacle.

Since the present invention has the above-described configuration, the locking step portion 12 of the actuating piece 7 and the front end beak portion 15 of the lock plate 10 which is pivotably supported directly below the locking step portion 12 are connected from the narrow safe ball socket 22. The inserted safe ball rotates the actuating piece 7 backward and moves it in elevation to the top dead center to form a wide-mouthed safe ball socket that expands the movable wing pieces 4, 4, and at the same time, the actuating piece 7 is completely held in its original position. A locking action that prevents unexpected fluctuations of the ball socket can be achieved with a simple mechanical structure, and the effect is that accurate operation can be expected.

Furthermore, if an interlocking pin 18 is provided on one side of the rear end of the lock plate 10 and protrudes from one side of the rear end of the actuating piece 7, when the movable wing pieces 4, 4' are raised, the movable wing pieces 4, 4' can be moved by appropriate related members. When the pin 18 is pushed down, the actuating piece 7
As the elevation angle moves in conjunction with the movable wing pieces 4,
4' is in the tilted state, and the actuating piece 7 engages with the lock plate 10 to maintain the elevation angle state in the same manner as when the safe ball is operated by the safe ball inserted into the narrow-mouth safe ball socket. also brings. The conventionally known safe ball socket main body 1 according to the embodiment of the present invention can vary the safe ball socket into two wide and narrow modes by the related operation of the movable blades 4, 4' and the lever-like actuating piece 7. It suffices if the narrow-mouth safe ball socket 22 has a transfer path regulating device 23 or not, and its actuating piece 7
If the lock plate 10 is combined with the lock plate 10, it is considered as a non-invention.
