Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an accessory for a ball and ball game machine.

[0002]

2. Description of the Related Art In recent years, in ball game machines typified by pachinko machines, symbols are variably displayed on a variability display portion in accordance with a winning start, and when a specific symbol is fixedly displayed, a big hit occurs. A game machine (for example, a “fever machine”), which has a closed winning opening in a closed state and can acquire a large number of prize balls, is gaining popularity. An accessory having a special winning opening is also referred to as an “attacker”, and has a structure in which a horizontally long winning opening is opened and closed by a corresponding horizontally-shaped closing member.
Normally, the closing member is hinged to the front plate or the like of the lower edge at both ends, for example, a closing position for closing the big winning opening, and an opening position for falling forward from the closing position and opening the big winning opening. In between, it is driven to open and close by a solenoid.

[0003]

By the way, in the above-mentioned attacker, the forward / backward displacement of the solenoid is transmitted to the closing member via the transmission mechanism.
A generally used solenoid actively excites only the movable rod by excitation, and uses a return force of a bias spring that elastically deforms when the movable rod advances when the movable rod is moved forward. Therefore, there is a disadvantage that the closing member can be easily pulled down from the closing position to the opening position as long as the force that overcomes the elastic force (usually not so large) of the bias spring is applied. For example, there is also a problem that the closing member is intentionally opened by inserting a wire or the like through a gap or the like in the pachinko machine front frame, and an award ball is illegally obtained even though a big hit state has not occurred.

In order to prevent the game ball from being pinched between the closing member and the front glass plate when the closing member falls to the open position, the transmission member constituting the transmission mechanism is coupled with a play of a fixed width. In many cases, a return displacement of the closing member in the direction of the closing position can be absorbed. However, in the configuration in which the closing member is returned from the open position to the closed position by the elastic return of the bias spring of the solenoid, the elastic return force is closed unless the spring returns by the sum of the play width formed between the transmission members. Not transmitted to the member. That is, when an attacker release end command is issued from the pachinko machine control unit as a solenoid excitation release command, a considerable time delay occurs before the closing member is actually closed. When such a delay occurs, more game balls than the limit set in one round of the jackpot enter the attacker, which may cause a trouble.

SUMMARY OF THE INVENTION An object of the present invention is to provide an accessory for a ball and ball game machine in which it is difficult to forcibly pull the closing member from the outside to the open position, and thus it is possible to effectively prevent illegal acts and the like. This is the first issue. It is a second object of the present invention to provide an accessory for a ball game machine which is unlikely to cause a delay in returning the closing member to the closed position due to the release of the bias of the drive actuator.

[0006]

[0010]

Embodiments of the present invention will be described below with reference to some embodiments shown in the drawings. (Embodiment 1) FIG. 1 schematically shows an example of a ball game machine to which an accessory for a ball game machine of the present invention (hereinafter, also simply referred to as "game item") is applied. . The ball game machine 1 has a structure in which a starting winning port 3, a fluctuation display section 4, an attacker 5 which is an embodiment of the character of the present invention, and the like are arranged on a game board 6, and is provided on a machine frame. By operating the firing handle 2 provided, the game ball is repelled toward the game board 6. Then, when the game ball wins the starting winning opening 3, it is determined whether or not the game is successful by a program process in an internal control unit (not shown), and at the same time, the change of the display symbol of the change display unit 4 is started. Then, when the contents (for example, a combination) of the symbols confirmed and displayed after the elapse of a predetermined time period are uniquely determined in response to the jackpot, the attacker 5 is opened, and the game ball is in a state where it is easy to win.

FIG. 2 shows the appearance of the attacker 5. As shown in (a), the attacker 5 has a front plate 10 in which a horizontally long winning opening (winning opening) 9 is formed,
A closing position (see FIG. 3) which is attached to the lower edge side of the special winning opening 9 via rotating fulcrums 15, 15 and closes the special winning opening 9
(State shown in FIG. 5 (a)) and an opening position (state shown in FIG. 5 (b)) that is opened and closed between the closed position and the open position (state shown in FIG. And Further, as shown in FIG. 2B, a case 8 in which a guide path for a winning ball, a known V zone opening / closing mechanism and the like are incorporated, and a drive actuator for opening / closing the closing member 11 are provided behind the front plate 10. (Linear actuator)
Is provided. The transmission mechanism 7 for transmitting the driving force of the solenoid 12 to the closing member 11 is also assembled in the case 8.

As shown in FIG. 3, the solenoid 12 and the transmission mechanism 7 are provided so as to correspond to one end of the horizontally long closing member 11 in the width direction. As we all know,
The solenoid 12 uses the movable rod 13 as a drive output unit and drives it to expand and contract by energizing and exciting a coil (not shown). At the tip of the movable rod 13, a slide member 24 serving as a first transmission main body is, for example, a rod. They are connected via a side engaging portion 14a and a member side engaging portion 24a. As a result, the slide member 24 is
Is driven in the opening and closing direction of the closing member 11 with the expansion and contraction of the closing member 11. The movable rod 13 is in a first displacement state when moved forward, and is in a second displacement state when retracted. A coil-shaped bias spring 14 is disposed coaxially with the outside of the movable rod 13, and is connected to the solenoid 12.
Is excited and the movable rod 13 moves backward, the solenoid 1
2 and the slide member 24 are compressed. When the excitation of the solenoid 12 is released, the bias spring 14 elastically returns to drive the movable rod 13 and the slide member 24 forward.

The transmission mechanism 7 includes the closing member 1 at the closing position.
When the movable rod 13 is in the advanced position (first displaced state) when a forcible operating force is applied to cause the closing member 11 to fall to the open position, the closing member 11 is prevented from moving to the open position. Also, it includes a function of a forced open protection mechanism that allows the closing member 11 to move to the open position when it is in the retracted position (second displacement state). Hereinafter, the details will be described.

First, the slide member 24 which is displaced in conjunction with the operation of the movable rod 13 functions as a first transmitting body, and the closing member driving as a second transmitting body which is displaced in conjunction with the first transmitting body. A part 16 is provided. The second transmitting main body is directly or indirectly connected to the first transmitting main body (slide member 24) on the side close to the closing member 11 via another member. Here, the closing member driving unit 16 as the second transmission main body is provided so as to be integrally rotatable with the closing member 11 around the rotation fulcrum 15 and not to be relatively rotatable.

Specifically, the closing member drive section 16 is formed in a plate shape extending obliquely downward from one edge in the width direction on the back side of the closing member 11, and is provided in a predetermined direction in the rotational radius direction from the rotation fulcrum 15. At a position separated by a distance, a shaft portion 18 as a driving action portion is formed. In this shaft portion 18, an intermediate transmission member 20, which will be described later, moves from
In the direction in which the opening / closing drive moment is generated.

A lock member 17 is freely rotatably connected to a lower end of the closing member driving portion 16 serving as a second transmitting body by a shaft portion 18, and a second side acting member is provided at an end near the slide member 24. A part 50 is formed. On the other hand, a first side action portion 51 is formed at a lower edge position of a front portion of the slide member 24. Note that the idle rotation limit of the lock member 17 to the rear side is set at the inner rear end of the closing member drive unit 16.
It is defined by a stopper 19 formed in a form projecting inward.

As shown in FIG. 3B, in the direction of the rotation axis # 1 of the closing member 11, on the side opposite to the closing member driving portion 16 with respect to the lock member 17, the shaft 22 substantially forms the rotation axis # 1. A plate-shaped intermediate transmission member 20 rotatably supported around a parallel axis # 3 is provided. The intermediate transmission member 20 abuts on the closing member driving portion 16 at the shaft portion 18 serving as a driving action portion, and plays a role of transmitting its own rotational displacement while converting it into a rotational displacement of the opening / closing member driving portion 16. The base portion of the shaft portion 22 is supported by a base portion 28 provided on the opposite side of the slide member 24 with respect to the intermediate transmission member 20 inside the case 8 (FIG. 2B).

The intermediate transmission member 20 is rotatably connected to the slide member 24 so that the slide displacement of the slide member 24 is converted into its own rotational displacement and transmitted. Specifically, the slide member 2 of the intermediate transmission member 20
4 is slidable into a transmission guide 25 formed on the back surface of the slide member 24 in a direction intersecting with the sliding direction (here, a direction orthogonal to the slide direction). The structure is arranged so as to be relatively rotatable around the axis. The transmission guide 25
Here, in a back case portion 27 formed on the back surface side of the slide member 24, for example, a U-shaped guide wall portion 26 protruding from the plate surface of the slide member 24 is formed.
To form a groove. In addition, the first side action portion 51
Is formed on the lower surface side of the back case 27 here.

On the other hand, the abutting portion of the closing member driving portion 16 with the shaft portion 18 is a guide wall portion 21 which defines both ends in the rotational circumferential direction around the shaft portion 22. here,
The guide wall portion 21 is formed in a notch shape cut in the plate surface direction at a predetermined width larger than the outer diameter of the shaft portion 18 from the end surface side of the intermediate transmission member 20 on the closing member drive unit 16 side. .

In the above mechanism, as the movable rod 13 advances and retreats, the slide member 24 as the first transmitting body reciprocates between the interference position moved forward and the retracted position retracted rearward. The slide member 24 serving as the first transmission body
When the drive output unit is in the first displacement state, that is, when the movable rod 13 is in the forward position, the closing member 11
When the forcible operation force is applied to move the closing member driving unit 16 to the open position, it moves to the inhibition position (FIG. 3 (a) or FIG. 4) which inhibits the displacement of the second transmission main body, that is, the closing member drive unit 16. Similarly, in the second displacement state, that is, when the movable rod 13 is at the retracted position, the allowable position (FIG.
Move to (a)). In this way, by using the transmission mechanism 7, the function of the forced opening protection mechanism can be rationally realized with a small number of parts.

Specifically, the closing member 11 at the closing position
Is forcibly displaced toward the open position, the closing member driving unit 16 rotates upward in conjunction with this. As shown in FIG. 4, the solenoid 12 (FIG. 3) is in a non-excited state, that is, the slide member 24 is located at the interference position. At this time, the first side action portion 51 is
7 is located on the path of the rotational displacement operation of the second side action section 50 (that is, the displacement path of the second side action section 50 is the first side action section 5 associated with the sliding displacement of the slide member 24).
0). When the closing member driving unit 16 rotates upward with the forced displacement operation of the closing member 11, the second side operating unit 50 interferes with the first side operating unit 51, and the displacement operation of the closing member driving unit 16 is performed.
That is, the movement of the closing member 11 to the open position is prevented.

On the other hand, as shown in FIG. 5 (a), when the solenoid 12 is excited,
Is moved to the retracted position, the first side operating portion 51 is retracted from the displacement path of the second side operating portion 50, so that a passage for moving the lock member 17 is opened. As a result, as shown in FIG. 6B, interference between the second side operating portion 51 and the first side operating portion 50 is avoided, and the displacement operation of the closing member drive unit 16, that is, the closing member 11 is moved to the open position. Is allowed. As shown in FIG. 3, in a state where the slide member 24, which is the first transmission main body, is located at the interference position and the closing member 11 is located at the closing position, the first side working portion 51
A predetermined amount of a buffer gap G is formed between the first side action portion 50 and the second side action portion 50. Then, as the closing member 11 is forcibly moved toward the open position, the closing member driving unit 16 and, consequently, the locking member 17 are displaced to reduce the buffer gap G, and the buffer gap G is eventually eliminated, and the first side operating unit is released. 51 and the second side working portion 50 come into contact with each other. At this time, the closing member 11 receives the special winning opening 9 by a predetermined amount which does not allow the game ball itself to be accepted.
Is half-opened. Thus, the closing member 11
Is configured to be able to be semi-opened from the outside within the minimum necessary range, which is convenient, for example, when performing maintenance of a gaming machine in a pachinko hall or the like.

The intermediate transmission member 20 has a receiving convex portion 23 as a driving action portion on which the sliding movement force of the slide member 24 acts, and is formed above the shaft portion 22 which is its own rotation shaft fulcrum. With the retreat of the member 24, the formation side of the guide wall 21 turns upward. As a result, the lower edge of the inner surface of the guide wall 21 is
8 is flipped up from below. At this time, as described above, since the slide member 24 has already retracted and the passage of the lock member 17 has been secured, the closing member 11 is moved by the lifting force from the intermediate transmission member 20 so that the closing member driving unit 1
6 together with the lock member 17 to fall forward by inertia,
This is the open position (FIG. 5B). Further, the shaft portion 18 also jumps upward due to the fall, but the upper limit position is defined by the upper edge of the inner surface of the guide wall portion 21 serving as a stopper. Therefore, the lower limit position of the fall of the closing member 11 is also defined by this. You.

By the displacement operation of the slide member 24, the first side action portion 51 completes the retreat of the second side action portion 50 from the displacement path before the second side action portion 50 arrives. The amount of formation of the buffer gap G is set.
With this, the first side working portion 51 and the second side working portion 50 are connected to the closing member 11 in the entire section from the closing position to the opening position as well as the state where the closing member 11 is located at the closing position. Unless a forced release operation is applied, the contact is practically non-contact. Therefore, even if the opening / closing operation of the attacker based on the normal game operation is repeated many times, the first side operating portion 51 and the second side operating portion 50 hardly wear due to contact, and conversely, the forced opening operation is not performed. If done,
A reliable interference contact state between the two can be ensured.

Next, when the excitation of the solenoid 12 is released, as shown in FIG.
The slide member 24 immediately starts moving forward due to the elastic return force of 4. In this embodiment, the transmission guide 25 and the shaft 23
Is formed to be 1/10 or less of the outer diameter of the shaft portion 23, and when the slide member 24 starts to advance, the intermediate transmission member 20 also immediately starts rotating in the opposite direction. . As described above, in the state where the closing member 11 is laid down to the open position, the shaft portion 18 is in contact with the upper edge of the inner surface of the guide wall portion 21, so that the closing member driving portion 16 and thus the closing member 11 also immediately starts moving toward the closed position.

Since the lock member 50 is attached to the shaft portion 18 so as to be freely rotatable, the inertia when the closing member 11 returns to the closing position with a certain amount of momentum causes the state shown in FIG. Easily return to. Even if the slide member 24 slightly hits the advancing slide member 24, strong interference can be avoided by slightly rotating forward.

As described above, the closing member 11 receiving the driving force from the intermediate transmission member 20 falls down by inertia together with the closing member driving portion 16, and the shaft portion 18 as the driving action portion is moved to the intermediate transmission member side upper limit regulation. Guide wall 21 as stopper
By contacting the upper edge of the inner surface of the first member, there is less delay in returning the closing member to the closed position. Further, the intermediate transmission member side upper limit regulating stopper portion (guide wall portion 2)
1 and an intermediate transmission member side lower limit regulating stopper portion (an inner surface lower edge of the guide wall portion 21).
When 1 is located at the open position, a gap (that corresponds to the notch opening width of the guide wall portion 21) is formed so as to allow the idle return to the closed position. The problem of ball biting between the two is unlikely to occur.

(Embodiment 2) FIG. 6 shows another embodiment of the attacker. Since the attacker 100 has many common parts with the attacker 5 of FIG. 1, the same reference numerals are given to the parts that are conceptually common, detailed description is omitted, and the differences will be described below. The differences are mainly the following three points. First, in this configuration, FIG.
The lock member used in the attacker 5 is omitted, and the upper surface of the rear end of the closing member driving unit 16 is
0 and the slide member 24 (the back case 2).
It is configured to interfere with the first side action portion 51 formed in 7).

Second, between the transmission guide 25 of the slide member 24 and the shaft portion 23 as the drive action portion of the intermediate transmission member 20, a predetermined amount of buffer gap L in the slide direction of the slide member 24 is provided. Are formed. further,
Third, the closing member 11 or the drive transmission member that directly drives the closing member 11, here, the intermediate transmission member 20,
An elastic member, specifically, a torsion spring 30 is provided as closing urging means for applying an urging force in a direction toward the closing position. As shown in FIG. 6B, in this embodiment, the winding portion of the torsion spring 30 is extrapolated to the shaft portion 22 between the intermediate transmission member 20 and the base portion 20, and one of the extending ends is a case. 8 side fixed base B
The other extension end is locked by a locking portion (a locking hole in this case) 31 formed at a lower front portion of the intermediate transmission member 20. When the intermediate transmission member 20 is to be turned upward, the torsion springs 30 have their extended ends approaching each other, causing torsional elastic deformation. Due to the elastic return force, the intermediate transmission member 2
0 is urged in the direction of turning downward, that is, in the direction of moving the closing member 11 to the closing position.

The operation of the attacker 100 is as follows. As in the case of the attacker 5 in FIG. 1, the slide member 24 is in the forward position when the solenoid 12 is not excited, and the closing member 11 is forcibly moved from the closing position to the opening position in this state as shown in FIG. In this case, the second side action portion 50 of the closing member driving portion 16 is
The opening is prevented by interfering with the first side working portion 51 of No. 4.

On the other hand, when the solenoid 12 is excited, the slide member 24 retreats as shown in FIG. 8A, but the buffer gap L is reduced and the front edge of the transmission guide 25 and the shaft 23 The intermediate transmission member 20 and, consequently, the closing member drive unit 16 do not start moving until the contact is made. That is,
Only the slide member 24 moves backward, so that the passage of the second side action portion 50 of the closing member drive unit 16 is naturally opened.
That is, the size of the buffer gap L is determined in accordance with the amount of retreat movement of the slide member 24 necessary for preventing the interference between the second side operating portion 50 and the first side operating portion 51 from occurring. .

When the front edge of the transmission guide 25 abuts on the shaft 23, the intermediate transmission member 20 pivots upward (the torsion spring 30 is elastically deformed at this time), as shown in FIG. As shown, the shaft portion 18 of the closing member drive unit 16 is flipped up, and the closing member 11 is moved to the open position, similarly to the attacker 5 of FIG.

Next, when the excitation of the solenoid 12 is released, the slide member 24 starts to move forward, but the intermediate transmission member 20 also immediately starts to rotate in the reverse direction due to the elastic return force of the torsion spring 30. Also, as in FIG. 1, the shaft portion 18 is in contact with the upper edge of the inner surface of the guide wall portion 21, so that the closing member driving section 16 and thus the closing member 11 also immediately start moving toward the closing position. I do.
During this time, the front edge of the transmission guide 25 and the shaft portion 23 are kept in contact with each other by the urging force of the torsion spring 30, so that the second side working portion 50 of the closing member driving portion 16
The slide member 24 returns to the original position without causing interference with the first side action portion 51. Thereafter, the slide member 24 further retreats and returns to the state of FIG.

In this configuration, due to the formation of the buffer gap L, the intermediate transmission member 20 and thus the closing member drive unit 16 do not start moving until the front edge of the transmission guide 25 and the shaft 23 come into contact with each other. Therefore, when it is not necessary to make the closing member 11 particularly semi-open, the buffer gap G is abolished, and
The second side operating portion 50 and the first side operating portion 51 may be in a state where they are in contact with each other. Further, the closing urging means may be constituted by a spring mechanism other than the torsion spring 30,
An appropriate weight is integrated with the lower end of the intermediate transmission member 20,
You may make it urge gravity downward.

(Embodiment 3) FIG. 9 shows a further embodiment of the attacker. This attacker 150 is shown in FIG.
Most of the configuration is the same as the attacker 100 of
They differ in the following points. That is, in this configuration,
The second side action portion 50 is formed not on the upper surface of the rear end of the closing member driving portion 16 but on the interference projection 35 protruding from the plate surface of the intermediate transmission member 20 on the slide member 24 side. The operation of the attacker 100 is as follows. That is, when the solenoid 12 is not excited, the slide member 24 is in the forward position, and as shown in FIG. 10, when the closing member 11 is forcibly moved from the closing position to the opening position in this state, the intermediate transmission member The second side action portion 50 formed on the interference projection 35 of the 20 interferes with the first side action portion 51 of the slide member 24 and is prevented from being opened. On the other hand, FIG. 11 shows the operation when the solenoid 12 is excited,
Since this is almost the same as the operation of the attacker 100 shown in FIG. 8, detailed description will be omitted.
