Description

[0001]
[Industrial applications]
The present invention relates to a mounting structure for a ball baffle plate and a ball stop plate attached to a tank rail of a pachinko machine.
[0002]
[Prior art]
Conventionally, as is well known, a mechanical plate made of synthetic resin is mounted on the back of the game board of a pachinko machine, and a ball tank is fixed to an upper portion of the mechanical plate. Further, a tank rail for guiding the pachinko balls of the ball tank to the pachinko ball dispensing device is provided below the ball tank, in order to rectify so that the pachinko balls do not overlap with the upper surface of the opening of the tank rail and flow down. And a ball stop plate provided with a ball stop piece that can enter the ball flow path of the tank rail and stop flowing down of the pachinko ball.
[0003]
The ball straightening plate and the ball stop plate are attached by, for example, as shown in FIGS. 9 and 10, by attaching a metal long shaft 103 having a screw portion 102 to a mechanism plate 101 on which a tank rail 100 is mounted, by a nut 104. The cylindrical portions 106 and 106 of the ball baffle plate 105 and the cylindrical portion 108 of the ball stop plate 107 are inserted into the shaft 103 and the plates 105 and 107 are rotatably supported on the shaft 103. Further, an E-ring 109 for retaining is fitted to the tip of the shaft 103.
[0004]
[Problems to be solved by the invention]
However, in the conventional mounting structure of the ball baffle plate and the ball stop plate, since the ball baffle plate and the ball stop plate are mounted on the mechanism plate separately from the tank rail, if the inclination of the tank rail is changed, There has been a problem that the corresponding positional relationship is deviated, and a correct ball rectifying action and ball stopping action cannot be expected.
[0005]
In addition, the use of metal shafts and E-rings increases the number of parts and increases the cost, and also requires time and labor to mount the components, thereby significantly reducing work efficiency.
[0006]

Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a rear view of a pachinko machine to which the present invention is applied, and FIG. 2 is a perspective view of a mechanism plate. In the figure, 1 is a front frame of a pachinko machine, 2 is a game board detachably mounted on the back of the front frame 1, and 3 is a mechanical plate made of synthetic resin mounted on the back of the game board 2 so as to be openable and closable.
[0011]
A ball tank 4 is fixed to an upper portion of the rear surface of the mechanism plate 3. Below the ball tank 4, there is provided a tank rail 5 for aligning and leading the pachinko balls of the ball tank 4. The downstream end of the tank rail 5 is connected to a pachinko ball payout device 7 via a bent rail 6. Therefore, the pachinko balls in the ball tank 4 are continuously supplied to the pachinko ball payout device 7 while being aligned by the tank rails 5 and the bent rails 6. A ball straightening plate 8 and a ball stopper plate 9 are disposed above the tank rail 5 near the downstream end.
[0012]
FIG. 3 is a perspective view of an essential part for explaining the mounting structure of the ball baffle plate 8 and the ball stop plate 9 which is a feature of the present embodiment. FIG. 4 is a diagram showing the ball baffle plate 8 and the ball stop plate 9 removed from the tank rail 5. FIG. 5 is an exploded perspective view of FIG. The tank rail 5 is formed in a gutter shape having an upper surface opened by a rear side wall 10 and a bottom portion 11 and a front side wall 12 which are in contact with the mechanism plate 3 by a synthetic resin, and a partition wall 13 is formed on the bottom portion 11 in a longitudinal direction. The two spherical flow paths 14 are formed. As shown in FIG. 4, opposing support portions 10a and 12a are integrally formed at the upper ends of the rear side wall 10 and the front side wall 12 located at the downstream end of the tank rail 5, respectively. , 12a are provided with through holes 101a, 121a for shaft insertion.
[0013]
The ball baffle plate 8 and the ball stopper plate 9 are each integrally formed of a synthetic resin. The ball baffle plate 8 is entirely formed in a flat plate shape corresponding to the ball passages 14 of the tank rail 5. The tip portion located on the upstream side of the tank rail 5 is gently curved upward. As shown in FIG. 5, bearing portions 8a and 8b are provided on both sides of the upper surface of the rear end portion located on the downstream side of the tank rail 5. The bearing portions 8a and 8b have insertion holes 81a and 81b at the center. One of the bearing portions 8a and 8b is formed to have a small thickness in the axial direction and has an insertion opening 811b at a smaller interval than the insertion hole 81b. Reference numeral 8c denotes a cylindrical weight portion provided on the upper surface of the ball baffle plate 8, and reference numerals 8d and 8d denote through grooves into which claw-shaped ball stopper pieces 9b and 9b of the ball stopper plate 9 described later protrude. .
[0014]
The ball stopper plate 9 is composed of two arms 9a and 9b located between the two bearing portions 8a and 8b of the ball baffle plate 8, and two claw-shaped spheres protruding into the through grooves 8d and 8d of the ball baffle plate 8. It has stop pieces 9c, 9c and a knob piece 9d. Shafts 91a and 91b are provided on the outer sides of the two arms 9a and 9b, respectively. The one shaft 91a is formed to be slightly longer than the axial thickness of the bearing 8a of the ball baffle 8. The shaft 91b is formed to be slightly longer than the shaft 91a.
[0015]
In the present invention having such a configuration, when the ball baffle plate 8 and the ball stopper plate 9 are attached to the tank rail 5, first, one shaft 91 a of the ball stopper plate 9 is inserted into the through hole of the bearing portion 8 a of the ball baffle plate 8. At the same time, the other shaft 91b is pressed against the insertion opening 811b of the bearing portion 8b of the ball baffle plate 8 and pushed into the insertion hole 81b, whereby the ball stopper plate 9 is moved as shown in FIG. 8 is rotatably supported. Next, the protruding end of the shaft 91a protruding from the bearing portion 8a of the ball baffle plate 8 is inserted into the through hole 101a of the tank rail 5, and the protruding end of the shaft 91b protruding from the other bearing portion 8b is penetrated by the tank rail 5. It is achieved by inserting it through the hole 121a.
[0016]
When the shaft 91b is inserted into the through hole 121a of the tank rail 5, the front wall 12 of the tank rail 5 is expanded while utilizing the elastic force of the synthetic resin. The elongated shaft 91b functions to reliably prevent the ball straightening plate 8 and the ball stopper plate 9 from being detached from the tank rail 5 after being attached to the tank rail 5. Further, by reducing the thickness of one bearing portion 8b of the ball baffle 8, the insertion opening 811b can be provided with expansion elasticity, whereby the insertion of the shaft 91b into the insertion hole 81b is easily and easily performed. I can do it.
[0017]
FIGS. 7 and 8 show another embodiment of the present invention, which differs from the first embodiment in that the arms 9a and 9b of the ball stopper plate 9 are formed to be long to provide elastic force. is there. In the case of this embodiment, the shafts 91a and 91b are inserted into the insertion holes 81a and 81b of the bearings 8a and 8b of the ball baffle plate 8 by bending the arms 9a and 9b inwardly by utilizing their elasticity. Can be. Therefore, it is not necessary to provide the insertion opening 811b in the bearing 8b as in the first embodiment. Also, there is no need to reduce the axial thickness of the bearing portion 8b, which is advantageous in terms of strength.
[0018]
【The invention's effect】
As described above, the mounting structure of the ball baffle plate and the ball stop plate attached to the tank rail of the pachinko machine according to the present invention is a simple structure, in which the ball baffle plate and the ball stop plate are directly mounted on the tank rail and integrated. Therefore, even if it is necessary to change the inclination of the tank rail, the corresponding positional relationship between the tank rail and the ball baffle and the ball stop plate does not change, so that the ball straightening action and the ball stopping action can be achieved. No adverse effects will occur.
[0019]
In addition, since the use of a metal shaft rod or an E-ring for retaining is not required, the number of parts can be reduced, and excellent effects such as improvement in workability and cost reduction can be exhibited.
