Description

  The present invention relates to a winning device for a pachinko machine including a movable wing piece that can swing in an open position where a game ball to be thrown into a game area can enter and a closed position where the game ball cannot enter.

  In a pachinko machine, when a game ball that has been driven into the game area wins the start winning opening, a movable wing piece arranged in the center of the game area triggers the game ball in the game object. It is advantageous for the player if the game ball that has entered the accessory moves from the closed position in which the player cannot enter the ball to the open position where the player can enter, and enters the V winning opening provided in the accessory. It is designed to generate special game rights.

  Usually, a solenoid having a plunger that moves straight when energized is used as a power source for opening and closing the movable blade piece. When the solenoid is energized and the plunger moves straight from the protruding position to the retracted position, the movable blade piece is moved from the closed position to the opening direction via the connecting lever connected to the plunger, and when the energization is stopped. The plunger is returned to the protruding position by the biasing force of the spring, and the movable blade piece is held in the closed position.

Further, the pin that moves integrally with the movable wing piece, when the movable wing piece moves in the opening direction by a predetermined amount, is engaged with the enlarged diameter portion of the engagement hole provided in the connecting lever, thereby driving into the game area. The movable wing piece is locked against the spring force so that it does not move from the closed position to the open direction against the spring force, for example, when the game ball hits the movable wing piece.

The relay link is capable of swinging the movable blade piece from the closed position to the open position and vice versa via the cam lever, and the relay link, when the solenoid is in an off state, A blocking portion that engages with a cam portion provided on the cam lever to prevent the movable blade piece from swinging in the opening direction, and a predetermined amount of swinging around the second rotation shaft in conjunction with the operation of turning on the solenoid. Move After the part is disengaged from the cam portion engages the engaging portion provided on said cam lever, and a engagement portion for oscillating the movable wing in the closed position.

(2) In the above item (1), assuming that the point where the blocking portion engages with the cam portion is an action point, a straight line connecting the action point and the center of the second rotation shaft is the action point. It is set to be substantially perpendicular to a straight line connecting the center of the first rotation axis.

According to the present invention, the following effects can be achieved.
According to the first aspect of the present invention, since the blocking portion of the relay link engages with the cam portion provided on the cam lever, the movable blade piece is securely held in the closed position, and the movement in the opening direction is reliably ensured. Can be blocked.

  According to the second aspect of the present invention, the movement of the movable blade piece in the opening direction can be reliably prevented with a simple configuration.

  Hereinafter, an embodiment according to the present invention will be described with reference to the drawings. FIG. 1 is a front view of a pachinko machine 1 to which the present invention is applied. In the following description, the front side of the drawing in FIG. 1 is “front or front surface”, the drawing surface is “rear or back surface”, the left side is “left”, and the right side is “right”.

  The pachinko machine 1 has an outer frame 2 installed in a gaming facility, a game board fixed in the outer frame 2 and formed with a circular game area 5 surrounded by an outer guide rail 3 and an inner guide rail 4 on the surface. 6 and a glass frame door 7 supported on the outer frame 2 while covering the surface of the game board 6 so as to be openable and closable.

  The game balls stored in the ball supply tray 8 provided below the glass frame door 7 are rotated by operating the operation handle 9 provided at the lower right of the glass frame door 7 to thereby produce a launching device (not shown). ), Is guided by the outer guide rail 3 and the inner guide rail 4 and is driven into the game area 5, and flows down while contacting a large number of game nails implanted in the game area 5. The game nails are omitted for simplification of the drawing.

  In almost the center of the game area 5, an accessory 20 that can receive a game ball that has been driven into the game area 5 is disposed. On the upper part of the accessory 20, an open position (a position indicated by a solid line in FIG. 1) where a game ball to be driven into the game area 5 can enter the accessory 20 and a closed position (imaginary in FIG. 1). The left and right movable wing pieces 21 are provided at a position indicated by a line. Below the accessory 20 in the game area 5, a first start winning port 10 and left and right second start winning ports 11 through which a game ball can win or pass are arranged. Further, at the bottom of the game area 5, there is provided an out port 12 through which game balls that have been thrown into the game area 5 are discharged to the back side of the game board 6.

  2 is a perspective view of the accessory 20 as viewed obliquely from the rear, FIG. 3 is a perspective view of an opening / closing mechanism 30 for opening and closing the movable wing piece 20, and FIG. 4 is an exploded perspective view of the opening / closing mechanism 30. is there. Since the left and right opening / closing mechanisms 30 have the same structure, only the opening / closing mechanism 30 that operates the left movable wing piece 21 will be described.

  The accessory 20 includes a box-shaped housing 22 that is fixed to the game area 5 and has an open front surface. On the upper part of the housing 22, the left and right movable blade pieces 21 are pivotally supported by a first rotating shaft 37 that faces in the front-rear direction so as to be swingable in the vertical direction. The movable wing piece 21 is opened and closed a predetermined number of times by the opening / closing mechanism 30 when a game ball has entered the first start winning opening 10 or the second starting winning opening 11.

  When the movable wing piece 21 is in the closed position, the swinging end is in a posture that faces obliquely upward, and when in the open position, the movable wing piece 21 is in a substantially horizontal posture and temporarily opens the upper portion of the housing 22. The probability that a game ball that has been driven into the game area 5 enters the accessory 30, that is, the housing 22 is increased. When a game ball entered in the housing 22 wins a V prize opening (not shown) provided in the housing 22, the movable wing piece 21 repeatedly opens and closes a predetermined number of times as a result. A special game state advantageous to the player is generated, and a predetermined game value is given to the player.

  The opening / closing mechanism 30 includes a base plate 31 fixed to the upper part of the housing 22, a solenoid 32 in which the plunger 41 can move straight in the left-right direction, a connection lever 33 connected to the plunger 41 of the solenoid 32, and a connection lever 33. The relay link 36 connected to the plunger 41 and the cam lever 38 that can swing integrally with the movable blade 21 are provided.

  The solenoid 32 includes a yoke 40 that is fixed to the base plate 31 and a plunger 41 that is supported by the yoke 40 so as to be movable in the left-right direction. The plunger 41 is urged in the protruding direction (rightward in FIGS. 5 to 8) by a conical coil spring 43 interposed between the plunger 40 and the urging force of the coil spring 43 when the solenoid 32 is turned on. Against this, it moves to the left from the protruding position (see FIG. 5), and when turned off, it returns to the protruding position by the urging force of the coil spring 43.

  The connecting lever 33 is pivotally attached to the plunger 41 by a connecting shaft 39 facing in the front-rear direction, and along the upper surface of the yoke 40 as the plunger 41 moves in the left-right direction when the solenoid 32 is turned on / off. Move left and right.

  The relay link 36 is pivotally supported by the base plate 31 by a second rotating shaft 35 that faces in the front-rear direction so as to be swingable in the vertical direction, and is connected to the operating end (left end) of the connecting lever 33 by the connecting shaft 34 that faces in the front-rear direction. When the plunger 41 is moved in the left-right direction by turning on and off the solenoid 32, the lock position (see FIG. 5) in an oblique posture facing leftward and upward via the connection lever 33 and the substantially horizontal posture is obtained. It swings back and forth around the second rotary shaft 35 between the open position. A shaft-shaped blocking portion 361 protrudes forward from the swing end portion of the relay link 36. Similarly, a cam that opens between the swing end portion and the second rotation shaft 35 opens. A groove-shaped engaged portion 362 is provided.

  The cam lever 38 is pivotally supported on the upper portion of the housing 22 so as to swing between the open position and the closed position integrally with the movable blade piece 21 via the first rotating shaft 37, and the upper arm portion 381 and the lower arm portion 381. The front view having the arm portion 383 is substantially C-shaped. A cam portion 382 is provided at the lower edge near the tip of the upper arm portion 381 so that the blocking portion 361 can be engaged obliquely from below when the relay link 36 is in the locked position, and at the end of the lower arm portion 383. A shaft-shaped engaging portion 384 that is loosely fitted to the engaged portion 362 is provided so as to protrude rearward. Furthermore, a stopper portion 385 that bends substantially downward at a right angle is provided at the tip of the upper arm portion 381. The stopper portion 385 is for ensuring the engagement between the blocking portion 361 and the cam portion 382.

  When the relay lever 36 swings from the lock position to the opening direction (counterclockwise in FIG. 5) by turning on the solenoid 32, the blocking portion 361 is detached from the cam portion 382 as shown in FIG. When 384 contacts the upper edge of the engaged portion 362, the cam lever 38 and the movable blade piece 21 move in the opening direction. That is, when the solenoid 32 is turned on, the relay lever 36 releases the lock that holds the movable blade piece 21 and the cam lever 38 in the open position in the initial stage movement, and then moves the movable blade piece 21 and the cam lever 38 in the open position. Move to. The engaging portion 384 is loosely fitted to the engaged portion 362 so that the engaging portion 384 of the cam lever 38 is not engaged with the engaged portion 362 until the blocking portion 361 is released from the cam portion 382. ing.

Next, the operation of the opening / closing mechanism 30 will be described with reference to FIGS.
As shown in FIG. 5, when the movable blade piece 21 and the cam lever 38 are in the closed position, the solenoid 32 is in the off state, the plunger 41 is held in the protruding position by the biasing force of the coil spring 43, and the relay link 36 is The locking lever 33 is held in the locked position. In this state, the blocking portion 361 of the relay lever 36 is engaged with the cam portion 382 of the cam lever 38, and the movement of the cam lever 38 from the closed position to the opening direction is blocked.

  This closed state will be described in detail. When the point where the cam portion 382 abuts against the blocking portion 361 is defined as an action point A, a straight line L1 connecting the action point A and the center of the second rotation shaft 35 is the action point. It becomes substantially perpendicular to a straight line L2 connecting A and the center of the first rotation shaft 37. Therefore, when the relay link 36 is in the locked position, the force in the opening direction input from the movable blade piece 21 acts toward the second rotation shaft 35 that is the rotation center of the relay link 36, It does not act in the direction of rotation. Therefore, the movable blade piece 21 and the cam lever 38 can be reliably held in the closed position without increasing the urging force of the coil spring 43. Further, even if a game ball that has been driven into the game area 5 collides with the movable wing piece 21 and acts to move the movable wing piece 21 in the opening direction, the blocking portion 361 can be connected to the cam portion 382. Therefore, the movable blade piece 21 does not rattle in the opening direction.

  Further, the force for holding the movable blade piece 21 in the closed position is sufficient as a small force sufficient to engage the blocking portion 361 with the cam portion 382. Therefore, the coil spring that biases the plunger 39 of the solenoid 32 to the protruding position. 43 can be made small. Thereby, insufficient suction force of the plunger 41 when the solenoid 32 is turned on can be prevented, and the movable blade piece 21 can be reliably moved to the open position.

  In the state shown in FIG. 5, when the solenoid 32 is turned on and the plunger 41 is attracted against the urging force of the coil spring 43, the operation is transmitted to the relay link 36 via the connecting lever 33. When the relay link 36 rotates by a predetermined amount from the lock position in the opening direction, as shown in FIG. 6, the blocking portion 361 moves to the left and separates from the cam portion 382, and the opening direction of the cam lever 38 and the movable blade piece 21. Unlock to prevent movement to. Immediately after the lock is released, the upper edge of the engaged portion 362 of the relay link 36 engages with the engaging portion 384 of the cam lever 38 to push down the cam lever 38 and the movable blade piece 21, and FIGS. 6 and 7. As shown in FIG. 8, the cam lever 38 and the movable blade piece 21 move to the open position via the state shown in FIG.

  When the cam lever 38 and the movable blade 21 move to the open position, the solenoid 32 is turned off, the plunger 41 returns to the protruding position by the biasing force of the coil spring 43, and the movement is transmitted to the relay link 36 via the connecting lever 33. Is done. When the relay link 36 rotates from the open position to the locked position, the lower edge of the engaged portion 362 engages with the engagement shaft 384 to lift the cam lever 38 and the movable blade piece 21, and at the final stage, the blocking portion The cam lever 38 and the movable blade piece 21 are moved to the closed position shown in FIG. 5 when the 361 contacts the stopper portion 385 and engages with the cam portion 382.

Although the embodiment of the present invention has been described above, the following various modifications and changes can be made to the present embodiment without departing from the gist of the present invention.
(I) The plunger 39 of the solenoid 32 is directly connected to the relay link 36.
(Ii) The engaged portion 362 of the relay link 36 has a protruding shape, and the engaging portion 384 of the cam lever 39 has a cam groove shape in which the protruding engaged portion 362 is loosely fitted.
