Description

  The present invention relates to a reversing motion mechanism suitable for moving up and down and swinging an accessory placed on a board surface of a pachinko game machine at a high speed.

  Various kinds of accessories are arranged on the board surface of the pachinko game machine, and there is one that raises the expectation of the big hit state by performing up and down or swinging motion.

  Such a movable accessory is easy to drive if it is lightweight and small, but recently, the weight has been increased by mounting a light emitting device and the size tends to be increased. For this reason, a small motor that can be incorporated into the game board can be moved only at a low speed, which is not interesting.

  Therefore, as shown in Patent Document 1, an exercise mechanism has been proposed in which a moving object that has been raised at a low speed is dropped to increase the downward movement speed. However, since this motion mechanism uses gravity, it could not be raised at high speed. Further, the movement is limited to the vertical direction, and it cannot be moved at a high speed in the horizontal direction. Furthermore, it was impossible to combine high speed and low speed movements.

  Accordingly, an object of the present invention is to provide a reversing motion mechanism that can move an object having a large mass at high speeds in the forward and reverse directions or a combination of high speed and low speed by a small motor that can be incorporated into a game board. is there.

  The reversal motion mechanism of the present invention made to solve the above-described problems includes a drive rotating body that can be rotated in both forward and reverse directions by a motor, a swinging member that is coaxially supported by the drive rotating body, A torsion coil spring suspended between the rotator and the swing member and biased by the drive rotator, a lock pawl for locking the swing member, and a lock pawl before, during or during the rotation of the drive rotator. It comprises release means that can be engaged and disengaged, and is characterized in that the rocking member is rocked by the torsion coil spring by releasing the lock claw while the torsion coil spring is biased.

  As in claim 2, it is preferable that the lock claw releasing means is a solenoid. According to the third aspect of the present invention, the swinging member can be swung by the torsion coil spring and the driving rotating body.

  The reversing motion mechanism of the present invention is such that the rotating member is rotated at a low speed by the motor while the swinging member is locked by the lock claw, the elastic energy is gradually accumulated in the torsion coil spring, and the lock claw is released. The rocking member is rocked by a torsion coil spring. If the capacity of the torsion coil spring is appropriately set, a rocking member having a large mass can be moved at a high speed. The operation can be alternately performed in the forward direction and the reverse direction.

  Further, the reversing motion mechanism of the present invention can engage and disengage the lock claw by a releasing means such as a solenoid before and after the rotation of the driving rotating body, so that the swinging member can be swung at a high speed by a torsion coil spring. Not only can this be performed, but part of the rocking motion can also be performed at a low speed by the drive rotor. In this way, it is possible to combine the high speed motion and the low speed motion by the same mechanism.

Embodiments of the present invention will be described below.
FIG. 1 is an overall perspective view showing an embodiment of the present invention, wherein 1 is a case, and 2 is a swinging member whose base is pivotally supported inside the case 1. Stoppers 3 and 3 are formed on both sides of the opening of the case 1 to regulate the swing angle of the swing member 2. The swing member 2 can be used as an accessory with its own decoration, or can be used as a drive lever for other accessories. The swing member 2 is not limited to a lever shape, and may be a gear, a pulley, or the like.

  As shown in FIGS. 2 to 4, the base of the swing member 2 is pivotally supported on the case 2 by a shaft 4, and the drive rotator 5 is also supported on the same axis as the shaft 4. ing. In this embodiment, the drive rotator 5 includes a gear 6 and can be rotated in both forward and reverse directions by a motor 7 and an intermediate gear 8.

  A torsion coil spring 9 is suspended between the drive rotator 5 and the swing member 2 as shown in FIG. The torsion coil spring 9 is rotatably supported on the cylindrical shaft 10 of the swing member 2 and includes two end portions 11 and 12 protruding outward. A projecting piece 13 extending between the end portions 11 and 12 is projected from the base portion of the swing member 2. Further, as shown in FIG. 4, the driving rotator 5 is also provided with a driving protrusion 14 extending between the end portions 11 and 12. The torsion coil spring 9 is actuated by the projecting pieces 13 and the driving projecting pieces 14, and the operation procedure will be described later.

  The outer periphery of the base of the swing member 2 is provided with an arcuate protrusion 23, and stepped engagement portions 15 and 16 are formed on both sides thereof. Reference numeral 17 denotes a lock claw provided in the vicinity thereof. The lock claw 17 swings about the shaft 18 and is urged by the spring 19 in the direction of the protruding portion 23. However, even before and after the rotation of the drive rotating body is performed by the solenoid 20 as a release means, Alternatively, it can be engaged / disengaged at an arbitrary timing even during rotation. Reference numeral 21 denotes a photosensor for detecting the rotation angle of the drive rotator 5.

Next, the movement of the reverse movement mechanism of the present invention will be described.
First, as shown in FIG. 5, the lock claw 17 is engaged with the engaging portion 15 of the swing member 2, and the swing member 2 is locked at the initial position where it is in contact with the stopper 3. At this time, the end 11 of the torsion coil spring 9 is in contact with the left end of the drive protrusion 14 of the drive rotator 5, and the other end 12 is in contact with the right end of the protrusion 13 of the swing member 2.

  When the drive rotator 5 is rotated clockwise by the motor 7 from the state of FIG. 5, the driving protrusion 14 moves the end 12 of the torsion coil spring 9 to the right as shown in FIG. The end 11 of the torsion coil spring 9 hits the protruding piece 13 of the swing member 2, but the swing member 2 does not move because it is locked. From this state, the drive rotator 5 is further rotated as shown in FIG. 7, and the torsion coil spring 9 is pushed and spread to sufficiently accumulate elastic energy. In addition, since this operation should just take time, even if the motor 7 is small, it can be performed without trouble.

  FIG. 8 shows the moment when the lock claw 17 is removed by the solenoid 20. As described above, the end portion 11 of the torsion coil spring 9 is in contact with the protruding piece 13 of the swing member 2 and is biased in the direction in which the end portions 11 and 12 are brought closer to the torsion coil spring 9. The member 2 swings rapidly in the clockwise direction as shown in FIG. 9, and stops at the reverse position of FIG. Since the swing member 2 swings instantaneously by the elastic energy accumulated in the torsion coil spring 9 as described above, when applied to the board surface of the pachinko machine, the accessory can be moved at high speed in any direction up, down, left and right. .

  After that, as shown in FIG. 11, the rocking member 2 is locked at the reverse position by the lock claw 17 and the motor 7 is reversed. Then, the driving projecting piece 14 causes the end 11 of the torsion coil spring 9 to move counterclockwise. As a result, the end 12 of the coil spring 9 stops at a position where it hits the projecting piece 13 of the swing member 2, and elastic energy is again accumulated in the coil spring 9. Thereafter, when the lock claw 17 is released, the swinging member 2 instantaneously returns from the inverted position of FIGS. 10 and 11 to the initial position shown in FIG. In this manner, the reversing motion mechanism of the present invention can swing the rocking member 2 having a large mass in the forward and reverse directions at high speed.

  In the embodiment described above, the swing member 2 is moved at high speed between the initial position and the reverse position. However, if the timing for releasing the lock claw 17 is changed as shown in FIG. High-speed movement can be combined.

  First, from the initial state of FIG. 12, the lock claw 17 is removed as shown in FIG. 13, and the drive rotating body 5 is rotated clockwise. When the driving rotating body 5 is further rotated while the driving projecting piece 14 is aligned with the projecting piece 13 of the swing member 2 as shown in FIG. 14, the end 11 of the torsion coil spring 9 is moved to the swing member 2. The projecting piece 13 is pressed, and the swinging member 2 rotates together with the drive rotator 5 as shown in FIG. For this reason, the swing member 2 swings at a low speed and stops at the reverse position of FIG. In this state, the rocking member 2 is locked by the lock claw 17 as shown in FIG. 17, and thereafter, if the elastic energy is accumulated in the torsion coil spring 9 as described above, it moves at a low speed from the initial position to the reverse position, in the reverse direction. Can be moved at high speed. Such an operation can be used for, for example, raising an accessory at a low speed and dropping it at a high speed.

  In other embodiments shown in FIG. 18 and subsequent figures, a large number of projections and depressions are formed on the arcuate protrusion 23 at the base of the swing member 2. These irregularities function as the engaging portion 22 of the lock claw 17. The starting end and the terminating end are the engaging portions 15 and 16 as described above. Next, the movement of the reverse movement mechanism of the present embodiment will be described.

  First, as shown in FIG. 18, the locking claw 17 is engaged with the engaging portion 15 on the start end side of the swinging member 2, and the swinging member 2 is locked at the initial position where it is applied to the stopper 3. At this time, the end 11 of the torsion coil spring 9 is in contact with the left end of the drive protrusion 14 of the drive rotator 5, and the other end 12 is in contact with the right end of the protrusion 13 of the swing member 2.

  From this initial state, the lock claw 17 is removed as shown in FIG. 19, and the drive rotator 5 is rotated clockwise. When the drive rotator 5 is further rotated while the drive protrusion 14 is aligned with the protrusion 13 of the swing member 2 as shown in FIG. 20, the end 11 of the torsion coil spring 9 is moved to the swing member 2. The swinging member 2 rotates together with the drive rotator 5 as shown in FIG. During this time, the swing member 2 swings at a low speed. If the retraction of the lock claw 17 is released by the solenoid 20 as shown in FIG. 22 at any timing during the low-speed movement, the lock claw 17 is advanced to a position where it comes into contact with the engaging portion 22 of the swinging member 2 by the spring 19. Then, when the engagement portion 22 in the middle coincides with the lock claw 17, the swing member 2 is locked and stopped as shown in FIG.

  When the drive rotating body 5 is rotated as shown in FIG. 24 while the swinging member 2 is locked in this way, the driving projecting piece 14 moves the end 12 of the torsion coil spring 9 to the right, and the torsion is performed. The coil spring 9 is spread and elastic energy is accumulated. Thereafter, when the lock claw 17 is released, the swinging member 2 instantaneously swings due to the elastic energy accumulated in the torsion coil spring 9 as shown in FIG. Stop. Thereafter, the drive rotator 5 may be reversed and returned to the initial position. However, the drive rotator 5 can be returned at a low speed or can be stopped once in the middle.

  As described above, according to the reversing motion mechanism of the present invention, by selecting the timing at which the lock claw 17 is engaged with the engaging portions 15, 16 and the intermediate engaging portion 22, various motions can be performed on the swing member 2. Can be done. For example, the driving rotating body 5 can be rotated in the reverse direction from the state where the swinging member 2 is stopped halfway, and returned to the intended position. Further, as described above, when the lock claw 17 is released in a state where the torsion coil spring 9 is not biased, the swing member 2 can be swung at a low speed by the motor 7, and various motions can be applied to the swing member 2. Can be performed.

  As described above, according to the present invention, there is an advantage that an accessory having a large mass can be moved in the forward direction or the reverse direction at high speed or at high speed and low speed by the small motor 7 that can be incorporated into the game board.
