BACKGROUND OF THE INVENTION
The present invention relates to an outer rail for guiding a game ball launched from a launching device in a pachinko machine to the game surface side.
[0002]
[Prior art]
Conventionally, in the game board 1 of the pachinko machine, as shown in FIG. 4, the outer rail 2 is attached in a predetermined curved shape and perpendicular to the front surface of the game board 1, and is returned to the guide end side of the outer rail 2. A rubber 3 is attached, and a decorative frame 4 having an arc surface 5 substantially continuous with the outer rail 2 is attached to the return rubber 3, and an inner rail 6 is connected to the arc surface 5 of the decorative frame 4 continuously with the outer rail 6. 2 is attached with a predetermined interval inside. Further, a return ball prevention holder 7 is attached to the rising end of the inner rail 6, and various patterns are won on the substantially circular game surface 8 surrounded by the outer rail 2, the decorative frame 4 and the inner rail 6. Mouth is formed.
[0003]
In forming the game surface 8, the outer rail 2 and the inner rail 6 are each provided with a mounting hole 9 at a predetermined interval at the lower edge of a stainless steel strip having a predetermined width as shown in FIG. A mounting bracket (nailing) 10 is attached to the game board 8 and is driven perpendicularly (at right angles) to the front surface of the game board 1 by a dedicated rail driving machine to form the game surface 8.
[0004]
[Problems to be solved by the invention]
However, in order to attach the outer rail 2 to the game board 1 in a predetermined curved shape and vertically, the outer rail 2 itself is made of a stainless steel strip. There is a problem that the cost becomes high because a dedicated machine for driving 2 is required. Further, since the outer rail 2 is mounted perpendicular to the game board 1, the game ball P launched from the launching device (not shown) is in contact with the outer rail 2 and the game board 1 as shown in FIG. Cause the player to become irritated because it is difficult to adjust the resilience of the game ball P because the travel track is not stable because the vehicle travels in a state where the outer rail 2 and the glass G surface are in contact with each other. In addition, when touching the glass G surface, there is a problem that unpleasant noise is generated and the player is further irritated. The present invention has been made in order to solve the above-described conventional problems, and can stably guide the shot ball from the launch device to the game surface side and prevent the generation of unpleasant noise. It is intended to provide an outer rail of a pachinko machine that can be used.
[0005]
[Means for Solving the Problems]
As described in claim 1, the game ball that is attached to the front surface of the game board set inside the glass for the window frame and is launched from the launch device provided below the game surface that is the game area is in curved outer rails to the top of the game board may induce a state of an arc, outer rails, the mounting piece in front view substantially semi-annular shape is attached in abutment on the front surface of the game board made by molding the guide rail is extended in a stenter greater than the diameter of the game ball toward the glass side from the inner peripheral edge of the mounting piece together by a synthetic resin material, further balls traveling guide of the guide rail by tilting the plane of the tilt angle at an acute angle to the front surface of the game board, the game balls induced on the game board in an arc, the game board front and the spherical traveling guide surface of the guide rail snap which is adapted to travel in contact with two points To provide the outside rail of the machine. According to the present invention, the game ball launched from the launching device is guided and traveled to the game surface side in a state where the game ball is in contact with two points in a substantially V-shaped groove formed by the guide rail and the game board surface. Since the guide rail of the outer rail is provided at a predetermined inclination angle toward the center of the game surface in this guided running state, even if the game ball tries to move to the glass surface side, the movement is suppressed by this inclination angle. In addition, since it is guided and driven to the game surface side with two points in contact with the substantially V-shaped groove, the generation of unpleasant noise caused by the conventional glass surface is prevented and the game ball is guided. Since the running is constant and stable, the game is coupled with the ability to adjust the resilience easily and accurately by visually checking the landing position of the game ball on the game surface side. Can alleviate annoyance. In addition, since the guide rail and the mounting piece are integrally formed of a synthetic resin material, the outer rail can be easily provided with a curved shape and an inclination angle of the guide rail, so that a conventional external rail dedicated machine is required. It can be easily attached and can be removed even once attached. Further, the structure of the molding die is simple, which is advantageous in terms of cost.
[0006]
【Example】
Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a plan view of the outer rail 11 of the present embodiment, and FIG. 2 is a cross-sectional view of the outer rail 11. The outer rail 11 is formed by injection molding of a resin material. The outer rail 11 is formed in a curved shape with a predetermined curvature with a length of a conventional attachment range of the outer rail 2, and its cross-sectional shape is a guide rail as shown in FIG. 12 and the mounting piece 13 are formed in a substantially L shape, and the mounting piece 13 is formed in a predetermined decorative shape, and a plurality of nail holes and screw holes 14 are provided therethrough.
[0007]
When the outer rail 11 thus formed is attached to the game board 1 along the guide rail 12 at a predetermined position via the attachment piece 13, the guide rail 12 is directed toward the center of the game surface 8. A substantially V-shaped groove portion 15 is formed between the guide rail 12 and the surface of the game board 1 so as to be inclined at an inclination angle α that forms an acute angle with the surface.
[0008]
In the pachinko machine to which the outer rail 11 formed in this way is attached, the game ball P launched from the launcher is substantially V-shaped formed by the guide rail 12 and the game board 1 as shown in FIG. It is guided to the game surface 8 side in a state in which two points are in contact with the groove portion 15. At this time, since the guide rail 12 of the outer rail 11 is inclined at an inclination angle α that forms an acute angle toward the center of the game surface 8, even if the game ball P attempts to move to the glass G surface side, the inclination angle α Thus, the movement is suppressed, and the vehicle is guided to the game surface 8 side while always in contact with the substantially V-shaped groove 15 at two points. Therefore, the generation of unpleasant noise caused by the conventional glass G surface is prevented and the guided travel of the game ball P is constant and stable, so that the landing position of the game ball P on the game surface 8 side is visually observed. It is possible to easily and accurately adjust the resilience while confirming with the above, thereby reducing the player's irritation.
[0009]
In addition, since the outer rail 11 is injection-molded with a synthetic resin material, the guide rail 12 and the mounting piece 13 can be integrally molded, and the curved shape and the inclination angle of the guide rail 12 can be easily attached. Installation can be easily performed without requiring an outer rail dedicated machine, and can be removed even if it is installed once. Further, the structure of the molding die is simple, which is advantageous in terms of cost.
[0010]
In the above-described embodiment, the outer rail 11 is formed by using only a synthetic resin material. However, the present invention is not limited to this. For example, the game ball P is in sliding contact with the same surface portion of the inclined inner side surface of the guide rail 12. 3, when the outer rail 12 is injection-molded as shown in FIG. 3, the stainless steel strip 16 is insert-molded along the inner surface of the guide rail 12 so that the game ball P is used. Abrasion can be prevented. Further, in consideration of wear on the game board 1 side (the game ball passage part) forming the guide rail 12 and the groove portion 15, a stainless steel plate is provided on the game surface 1 side, or the insert is inserted into the outer rail 12. In place of the stainless steel strip 16 to be formed, it is more effective to insert and attach a stainless member bent into a substantially L-shaped cross section.
