[Detailed description of the invention] (Field of industrial application) This invention consists of a launch rail 1 installed in the launcher section of a pachinko machine 6 and a game board 7 of the pachinko machine 6.
The present invention relates to a rail body of a pachinko machine 6 such as a guide rail 2 installed in a game board 7 for guiding a pachinko ball B to a game surface 8 of a game board 7 (see FIG. 1).

(Prior Art) Conventionally, the launching rail 1 and the guiding rail 2, which are the rail bodies of the pachinko machine 6, have been made of corrosion-resistant material in order to make the pachinko ball B run smoothly and to maintain the directionality of the launching of the pachinko ball B. Stainless steel was used, and the surface of the launch rail 1 was plated with hard chrome to provide wear resistance.

(Problem to be solved by the invention) However, stainless steel generally has poor workability and is expensive, and it passes over the rail body frequently and in large quantities (with electric pachinko machines used recently, stainless steel There was a problem in that the surface was easily damaged by Pachinko balls B (about 100 Pachinko balls are fired), the rail body was easily damaged in a short period of time, and furthermore, the damage caused rust. Damage or rust to the rail body is a fatal problem for the pachinko machine 6 because it changes the launch direction or flight distance of the pachinko ball B. To avoid this problem, The only option was to frequently replace the rail body parts.

Nitriding is a method for hardening the surface layer of a workpiece by bringing it into a nitrogen-rich state, and uses nitrogen generated when ammonia is decomposed at high temperatures as a nitrogen source. Specifically, the treatment is performed by heat-treating the object in an atmosphere of ammonia or a mixed gas of ammonia and carbon dioxide, ammonia and methane, or the like. The heat treatment is preferably performed at a temperature in the range of 500 to 800℃, and the lower the temperature or the thinner the surface treatment layer of the object to be treated, the shorter the treatment time, but usually
It takes about 0.5 to 4 hours.

As the wax 4, corrosion-preventing metal soaps such as calcium, chromium, and zinc can be used. In addition, a lubricating wax 4 may be used, and the components of the wax 4 are not particularly limited. This wax 4 coating may be applied by dipping the nitrided rail member in a wax 4 solution, or by wiping the rail member by spraying or the like.

In general, the surface of the nitrided object becomes rough, but it has good adhesion to the wax 4 coating, which helps prevent the wax 4 from peeling off from the rail member 3 (see FIG. 2).

Note that the rail member heat-treated by the nitriding process is cooled, and the cooling is preferably performed by rapid cooling into an emulsion of water and oil. Prior to this cooling,
If the object to be treated is oxidized by exposing it to the air for several seconds (2 to 20 seconds), the corrosion resistance of the object will be further improved. In this case, the surface of the object to be processed becomes black, resulting in a rail body that is not conventionally (conventionally, silver), and it is possible to form a game board 7 with a different design.

The rail body thus obtained has excellent corrosion resistance (corrosion resistance of more than 200 hours in a salt spray test) and wear resistance (Vickers hardness of approximately 1000 degrees (harder than ordinary hardened blades)), and is coated with Wax 4. The surface is smooth and allows pachinko ball B to slide easily.

In addition, especially when lubricating wax is used as the wax, taking advantage of its good sliding properties, the firing rail 1 is formed into a cylindrical shape, as shown in FIG. be able to. In other words, the conventional launching rail 1 has a V-groove formed in the center of the flat rail surface, on which the pachinko ball B is made to travel, but the hammer that launches the pachinko ball B has a V-groove that is designed to launch the pachinko ball B at the same time. Due to the repetition, the position where the pachinko ball B is hit may be slightly shaken, and for this reason, with the conventional launch rail 1, the pachinko ball B sometimes flies out of the V-groove and cannot maintain directionality. On the other hand, in order to obtain stability in the directionality of the pachinko ball B, it is conceivable to make the contact point between the pachinko ball B and the launch rail 1 larger, but if it is made larger, the friction that the pachinko ball B can withstand increases, and the ball The slippage becomes worse. However, if a rail body coated with lubricating wax is used as described above, even if it is cylindrical, the inner surface 5
Since the whole ball has good sliding, the pachinko ball B can run smoothly and the ball can have stability in direction.

(Effects of the invention) As described above, the rail body of the pachinko machine according to the present invention does not use stainless steel, which is difficult to process, as in the past, but uses a relatively soft material and hardens it after processing, so the structure of the rail body is improved. It has the advantage that even if it is complicated, it can be easily processed.
In addition, the rail body of the present invention is made by nitriding the surface of the rail member and then coating it with wax, so it has excellent corrosion resistance and abrasion resistance, and the smooth surface makes it easier to hold pachinko balls. It can run smoothly. In particular, coating the rail body with wax for lubrication will improve the sliding of the rail body more than ever before, so the rail body can be made into a shape that has more contact with the pachinko balls, such as a cylindrical shape. can be made more stable.

Furthermore, from a manufacturing standpoint, there is no problem with sewage caused by the conventional hard chrome plating process, and the rail body can be manufactured at low cost.
