Abstract

PROBLEM TO BE SOLVED: To provide a tank rail of a pachinko machine resisting jamming of balls. SOLUTION: The downgrade angle θ1 of a first inclined passage 37 where game balls P flowing out of the exit 21 of a ball tank 20 first drop is greater than the downgrade angle θ2 of a second inclined passage 40, so that the initial speed of the game ball P at its drop point when the game ball P coming out of the exit 21 drops onto the second inclined passage 40 can be made higher than the initial speed of the game ball at its drop point when it is assumed to drop onto an inclined passage with the same downgrade angle as the downgrade angle θ2 of the second inclined passage 40. Thus, even if the number of game balls P coming out of the exit 21 increases, the number of game balls P which flow down can follow this increase, preventing the jamming of the game balls P at the drop point.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tank rail of a pachinko machine for guiding game balls flowing out of a ball tank for storing game balls on the upstream side of the pachinko machine to the downstream side.

[0002]

2. Description of the Related Art Conventionally, for example, a tank rail of this type is known as shown in FIG. FIG.
(A) is an explanatory view showing a role of a tank rail provided in a conventional pachinko machine. In the following description, the supply side of the game balls is referred to as an upstream side, and the side on which the game balls flow is referred to as a downstream side. A ball tank 81 is provided above the back setting mechanism plate 80 of the pachinko machine.
A tank rail 83 is attached to a lower portion of the first rail 1.
The ball tank 81 stores the game balls P supplied from a ball supply path provided at the top of an island (not shown). Ball tank 81
A ball flow outlet 82 is formed at the bottom of the game ball P, and the game balls P stored in the ball tank 81 flow out of the ball flow outlet 82 to the upstream side of the tank rail 83. The bottom surface inside the tank rail 83 is slightly inclined downward from the upstream side to the downstream side, and the game ball guiding rail 8 is provided on the downstream side.
4 are connected. That is, the game ball P flowing out to the upstream side of the tank rail 83 rolls on the bottom surface inside the tank rail 83 and is guided to the game ball guide rail 84 on the downstream side. On the downstream side of the game ball guiding rail 84, a prize ball unit 85 for paying out the guided game ball P as a prize ball is provided, and on the downstream side of the prize ball unit 85, a guided game is provided. A ball lending unit 86 for lending the ball as a ball lending is provided.

[0003]

However, the above-mentioned conventional tank rail 83 has a problem that ball clogging sometimes occurs. For example, FIG. 5B is an explanatory view showing an example of a state in which a ball is clogged in the tank rail 83. As shown in FIG. 5B, a ball discharge port 82 of a ball tank 81 and a game ball discharged therefrom are shown. The ball may be clogged with the bottom surface of the tank rail 83 on which the water drops. This is because when the amount of the game ball P flowing out from the ball tank 20 to the tank rail 83 increases, the tank rail 83
It is considered that the cause is that the amount of the game balls P flowing down the ball cannot follow, and the game balls P are congested between the ball outlet port 82 and the bottom surface of the tank rail. in this way,
When the ball is clogged, call the pachinko hall clerk,
Since it is necessary to open the back set mechanism plate 80 to clear the ball clogging, there is a problem that it is troublesome,
There is also a problem that the fun is halved because the game is interrupted. In addition, some players try to clear the ball clogging by vibration by hitting the game table, but if you hit the game table in this way, it will make the surrounding players unpleasant. Would. Further, if a ball hit occurs when a large hit occurs when the number of balls possessed is small, there is a problem that the number of game balls to be driven becomes insufficient, and an opportunity to acquire a large amount of prize balls is missed. In addition, it is conceivable to solve the above-mentioned traffic jam by increasing the descending angle of the tank rail 83 and increasing the falling speed of the game ball P flowing down the tank rail 83.
The maximum height H2 in the up-down direction required when attaching 3 to the back setting mechanism plate 80 increases, which is not desirable because it is necessary to change the attachment position of other structures. On the other hand, if the falling speed is too high, the game balls P are excessively concentrated on the downstream game ball guide rail 84, and there is a possibility that ball clogging may occur at the concentration point.

Accordingly, the present invention has been made to solve the above-mentioned problems, and has as its object to realize a tank rail in which ball clogging is unlikely to occur.

[0005]

According to the present invention, in order to achieve the above object, a game flowing out of an outlet of a ball tank for storing game balls on an upstream side is provided. In a tank rail of a pachinko machine for guiding a ball to a downstream side, a first ramp for guiding a game ball flowing out from the outlet to the downstream side, and the game ball guided to the downstream side by the first ramp. A second ramp for guiding the game ball further to the downstream side, wherein a down-slope angle of the first ramp is larger than a down-slope angle of the second ramp. Is used.

That is, the downward slope angle of the first ramp is:
When the initial velocity at the point where the game ball that has flowed out of the outlet falls first because it is larger than the downward slope angle of the second ramp, falls on an inclined surface having the same angle as the downward gradient angle of the second ramp. Can be faster than the initial speed. Therefore, even when the number of the game balls flowing out of the outlet increases, the number of the game balls flowing down can be made to follow the increase. Does not occur. Also,
Since the descending slope angle of the second ramp is smaller than the descending slope angle of the first ramp, the acceleration of the downflow speed of the game ball that has flowed down from the first ramp can be relaxed. Ball clogging due to excessive inflow of game balls can be eliminated. In addition, only the down slope angle of the first ramp needs to be increased, and it is not necessary to increase the down slope angle of the entire tank rail. Therefore, the maximum vertical height required when mounting the tank rail is increased. There is no need to change the mounting position of other structures.

According to a second aspect of the present invention, in the tank rail of the pachinko machine according to the first aspect, a technical means is used in which the first slope is formed in a stepped shape.

That is, by forming the first ramp in a step shape, the initial velocity of the game ball flowing out of the outlet of the ball tank can be relaxed and the flow can be made smoother.

According to the third aspect of the present invention, in the tank rail of the pachinko machine according to the first or second aspect, the downward slope angle is gradually reduced from the upstream side to the downstream side. Use technical means that

In other words, on the upstream side, the flow speed of the game balls flowing out of the outlet is increased, so that the congestion of the game balls at the drop point of the game balls is eliminated. Ball clogging due to excessive inflow of game balls on the side can be eliminated.

I have. That is, the game ball P stored in the ball tank 20 is guided to the game ball guide rail 50 by rolling on the bottom surface of the tank rail 30. Game ball guidance rail 50
A prize ball unit 60 is provided below the prize ball unit 60 via a rail 16, and a ball lending unit 70 is provided below the prize ball unit 60 via a rail 17. Although not shown, three rails are formed in the vertical direction in the inside of the game ball guide rail 50, two of the three rails are connected to the prize ball unit 60, and one of the rails is It is connected to the ball lending unit 70. Also, on the back setting mechanism plate 11, there are provided circuit boards 12, 1 for performing various controls of the game.
3, 14 and a launch motor 15 for driving a launch device for launching a game ball to a game board are provided.

[Structure of Tank Rail] As shown in FIG. 2, the tank rail 30 is provided with a back setting mechanism plate 11 (FIG. 1).
Is provided with a back plate portion 33 facing the rear plate portion 3.
A front plate portion 34 is formed at a position facing the front plate 3 at a predetermined distance. A curved plate portion 36 is formed so as to swell in the front direction from the middle of the front plate portion 34 toward the upstream side 31. A left side plate 35 is formed between the upstream end of the curved plate 36 and the upstream end of the back plate 33. The lower end of the back plate 33 and the front plate 34
A bottom plate 38 is formed between the lower end and the lower end. A first inclined path 37 is formed, which is steeply inclined downward from a position slightly lower than the upper end of the left side plate 35 toward the upstream end of the bottom plate 38.

[0015] The second slope 37 has a downward slope at a gentle angle from the lower end 37b on the downstream side of the first ramp 37 toward the downstream side.
Ramp 40 is formed. That is, the flow path of the game ball on the bottom surface of the tank rail 30 is formed so that the downward slope angle becomes gentler from the upstream side to the downstream side. A partition plate 41 is provided on the second slope 40 from the upstream side to the downstream side with a predetermined distance between the plate surface thereof and the plate surface of the rear plate portion 33 and the rear plate portion 3.
3 is formed so as to face the plate surface. The partition plate 4
A partition plate 42 is formed between the front plate portion 1 and the front plate portion 34 at a predetermined distance from each of the plate surfaces and opposed to each plate surface. That is, the second inclined path 37 is divided into three flow paths from the upstream side to the downstream side by the two partition plates 41 and 42.

In FIG. 3A, reference numeral L1 indicates a parallel line parallel to the installation surface 18 of the pachinko machine 10 (FIG. 1).
The parallel line L4 parallel to the parallel line L1 is connected to the first ramp 37.
Is drawn to intersect with the lower end 37b of the first ramp 37
Is assumed to be θ1. In addition, a parallel line L2 parallel to the parallel line L1 is drawn so as to intersect the downstream end of the second ramp 40, and the downward gradient angle of the second ramp 40 is θ2.
And In this embodiment, θ1> θ2, for example, θ1 = 20 ° to 45 °, and θ2 = 5 ° to 10 °. In addition, when the second inclined surface 40 is extended to the upstream side, the extension line is L3, the perpendicular from the upper end 37a of the first inclined path 37 to the parallel line L1 is L5, and the extension line L3.
Assuming that an intersection at which C and the perpendicular L5 intersect is C1, a distance H1 exists between the intersection C1 and the upper end 37a. Here, assuming that the extension line L3 of the second ramp 40 is substantially equal to the extension line of the bottom surface of the conventional tank rail, the intersection C1
Substantially coincides with the upper end of the bottom surface of the conventional tank rail. That is, the upper end 37a of the first ramp 37 is formed closer to the outlet 21 of the ball tank 20 by the distance H1 than the upper end of the conventional tank rail, and the first ramp 37 Is larger than the conventional downward slope angle of the bottom surface of the tank rail.

[Flow of Game Ball in Tank Rail 30] As shown in FIG.
When the game ball P which has flowed downward from 1 falls on the first slope 37, it flows down while rapidly accelerating at the same time as the fall because of the steep descending slope, and falls on the second slope 40. Subsequently, the game ball P flows down the second ramp 40 while gradually decreasing the acceleration due to a gentle downward gradient, and then flows into the game ball guide rail 50 (FIG. 1).

[Effects of the First Embodiment] As described above, if the tank rail 30 of the first embodiment is used, the first game ball P which flows out from the outlet 21 of the ball tank 20 first falls. Since the descending slope angle θ1 of the slope 37 is larger than the descending angle θ2 of the second slope 40, the outlet 2
It is assumed that the initial velocity at the falling point when the game ball P flowing out from the first drop falls on the second ramp 40 falls on the ramp having the same downward gradient angle θ2 as the downward gradient angle θ2 of the second ramp 40. It can be faster than the initial speed at the fall point in the case. Therefore, since the number of the game balls P flowing down from the outlet 21 can follow the increase in the number of the game balls P flowing down, the game balls P are congested in the portion where the game balls P fall and the ball is clogged. I won't.
Further, since the descending gradient angle θ2 of the second ramp 40 is smaller than the descending gradient angle θ1 of the first ramp 37,
Since the acceleration of the falling speed of the game ball P flowing down from the inclined path 37 can be reduced, the ball clogging due to the excessive inflow of the game ball P on the downstream side can be eliminated. Further, only the down slope angle θ1 of the first ramp 37 needs to be increased, and it is not necessary to increase the down slope angle of the entire tank rail 30. Therefore, the maximum vertical height required when the tank rail 30 is mounted is required. Since it is not necessary to increase the height H2 (FIG. 3A), there is no need to change the mounting position of another structure. In FIG. 3A, a line indicated by reference numeral L6 is a parallel line drawn in parallel with the parallel line L1 from the lowermost end on the most downstream side of the tank rail 30.

<Second Embodiment> Next, a second embodiment of the present invention will be described with reference to FIG. FIG. 4 (A)
FIG. 4 is a perspective explanatory view showing a part of a tank rail in a flowing direction omitted, FIG. 4 (B) is a plan view of the tank rail shown in FIG. 4 (A), and FIG. It is a front view of FIG. Except for the first ramp which constitutes the tank rail, the structure is the same as that of the first embodiment, and the description of the same parts will be omitted.

The first ramp 37 has an upper end 37 at the most upstream side.
a having a and having a downward slope inclined downstream 37c
And a slope 37d having an upper end at a position slightly lower from the downstream end of the slope 37c, and inclined downhill to the downstream, and slightly from the downstream end of the slope 37d. An inclined path 37e having an upper end at a position descending downward and having a downward slope inclined downstream. That is, the first
Is formed in a total of three steps that descend to the downstream side. Further, each of the ramps 37c, 37d, 3
Each downward slope angle of 7e is larger than the downward slope angle of the second ramp 40, respectively. Thereby, the ball tank 20
The game ball P flowing out from the outlet 21 of the falling, since the descending slope angle of the ramp 37c that falls first is steep,
It immediately flows down to the next ramp 37d, and subsequently flows down to the next ramp 37e. Then, the ball falls on the second ramp 40, and gradually reduces the acceleration while guiding the game ball guiding rail 50.
(FIG. 1).

[Effects of the Second Embodiment] As described above, if the tank rail 30 of the second embodiment is used, like the tank rail 30 of the first embodiment, the first ramp 37 is used.
Is formed in a step-like shape having slopes 37c, 37d, and 37e having a descending slope angle larger than the descending slope angle of the second slope 40, so that the game balls P flowing out from the outlet 21 increase. Therefore, since the number of flowing game balls P can follow, the game balls P are not congested at the portion where the game balls P fall, and the ball is not clogged. Further, since the descending slope angle of the second ramp 40 is smaller than the descending gradient angle of the first ramp 37, the first ramp 3
Since the acceleration of the downflow speed of the game balls P flowing down from 7 can be reduced, it is possible to eliminate the ball clogging due to the excessive inflow of the game balls P on the downstream side. Further, only the down slope angle of the first ramp 37 needs to be increased, and it is not necessary to increase the down slope angle of the entire tank rail 30. Therefore, the maximum height required in the vertical direction when the tank rail 30 is mounted. Since it is not necessary to increase H2, there is no need to change the mounting position of another structure. Furthermore, the first
Is formed in a step-like manner, so that the initial velocity of the game ball flowing out of the outlet 21 of the ball tank 20 can be relaxed and the flow can be made smoother.

<Other Embodiments> (1) In the first embodiment, the case where the surface shape of the first ramp 37 is a plane has been described, but the surface shape is curved downward or arcuately elliptical. It can also be formed. In the case of forming this surface shape, the downward slope angle at the point where the game ball falls is formed so as to be larger than the second slope 40. Thereby, substantially the same effect as the tank rail 30 of the first embodiment can be obtained. Also, the first ramp 3
7 to the second ramp 40 can also be formed in a continuous shape without a step. (2) Among the ramps 37c, 37d, and 37e constituting the first ramp 37 in the second embodiment, the ramp 37
The downward slope angle of c may be formed to be larger than the downward slope angles of the other inclined paths 37d and 37e. Also, the first
May be two or four or more. Furthermore, the first part, the middle part, or the last part of the step portion may be formed not in a step shape but in a flat shape or a curved shape with a downward slope.
