Abstract

(57) [Summary] [Purpose] To provide a hammer tip member for a pachinko machine that has a wide ball-hitting surface, can completely transmit the ball-hitting force to the ball, and has no fluctuation in ball flight even after long-term use. [Structure] The tip portion of the coil spring 3 is tightly wound, and a ceramic material 4 covering the tip surface of the coil spring 3 is fixed to this portion using the elasticity of the coil spring 3.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention is a hammer tip member for pachinko machines that is attached to the tip of a pinball mallet of a pachinko machine. It is related to

0002

[Conventional technology]

Metal coil springs are generally used as the hammer tip parts for conventional pachinko machines. ing. However, such a coiled mallet tip spring has variations in the end winding position of the tip. The center of the annular ball hitting surface at the tip should be aligned with the center of the short mallet. It takes a lot of work to attach it to the hammer, and it is difficult to attach the handle set after attaching it to the short hammer tip. Even when attached to a pachinko machine, due to slight errors in the thickness of the plywood, etc. Inside the pachinko ball located at the center of the tip of the coiled mallet tip spring and the base of the ball hitting rail. This caused his mind to deviate from the proper ball hitting position, which required adjustment. Furthermore, this coiled hammer tip spring will suffer from metal fatigue due to direct impact if used for a long period of time. This caused an impact on the flight of the ball.

0003 Therefore, as shown in Japanese Utility Model Publication No. 58-18942, a ball with a wide hitting surface is attached to the tip of the mallet tip spring. Elastic plastic materials such as urethane have also been developed. Plastic material absorbs the force of the ball when you hit it, so you should either strengthen the tension spring or use the hammer. Another problem occurred in that the length had to be increased to provide stronger hitting power.

0004

[Problem that the idea aims to solve]

This invention solves the above-mentioned conventional problems, provides a wide hitting surface, and provides sufficient hitting power. A pachinko machine that can transmit information to the ball accurately and that does not change the flight of the ball even after long periods of use. It was completed to provide a hammer point member.

[0005]

[Means to solve the problem]

The present invention was developed to solve the above problems. The tip of the spring is wrapped tightly and a ceramic material is used to cover the tip of the coil spring. It is characterized in that it is fixed.

[0006]

【Example】

The present invention will be explained in more detail below by means of illustrated embodiments. Figure 1 shows the first embodiment of the present invention, where 1 is a ball mallet and 2 is a ball at the tip. The metal hammer tip short rod 3 is a coil spring. This coil spring 3 has an effective spring winding part in the center, but the tip and base end are tightly wound. It has a rolled part and is fixed by wrapping the base part around the hammer tip short rod 2.

[0007] In addition, the tip of the coil spring 3 is covered with a densely wound portion at the tip of the coil spring 3. A ceramic material 4 is fixed thereon. The material of the ceramic material 4 used in the present invention is not particularly limited. However, considering hardness and impact resistance, for example, alumina ceramics and zirconia ceramics are used. Lamic or the like can be used.

[0008] The ceramic material 4 in FIG. The leg portion 4b is press-fitted into the tip of the coil spring 3 and connected. It is attached with adhesive. However, as shown in the upper right of FIG. Form a screw 5 equal to the lock and screw it into the inside of the coil spring 3. It can also be fixed. In either case, spread out the tip of the coil spring 3. By inserting the leg portion 4b into the sea urchin, the elasticity of the coil spring 3 will ensure secure fixation. Wear.

[0009] In the second embodiment shown in FIG. 2, a cap-shaped ceramic material 4 is used. Ru. In this case, the inner diameter of the recess on the back side should be slightly smaller than the outer diameter of the coil spring 3. Then, use the adhesive force of the adhesive and the elasticity of the coil spring 3 to attach the tip. It is preferable to keep it fixed at .

[Effect]

The hammer tip member for a pachinko machine of the present invention configured as described above is provided at the tip of the coil spring 3. is covered with ceramic material 4, ensuring a wide ball-hitting surface, compared to conventional It is easier to assemble and allows for more stable ball hitting compared to those made only of coil springs. be able to. Moreover, compared to conventional elastic plastic materials such as urethane, ceramic material 4 This allows the ball to be completely transmitted to the ball without absorbing the force of the ball. , a good ball flight can be obtained.

[0011] In addition, ceramic material 4 has high hardness, so there is no risk of wear and tear even after long-term use. Moreover, it has the effect of preventing metal fatigue of the coil spring 3, so it can be used for a long time. It is possible to guarantee a stable ball flight. Furthermore, as in the embodiment, the ceramic material 4 is applied to the tightly wound portion of the tip of the coil spring 3. If the coil spring 3 is attached using its own elasticity, the ceramic material 4 will not loosen. It has the advantage that there is no risk of it falling off.

[Effect of the idea]

As explained in detail above, the pachinko machine hammer tip member of the present invention has a wide ball hitting surface. What you get is that you can completely transmit the batting force to the ball, and even after long-term use. It has many advantages, such as no fluctuation in ball flight, so it overcomes the problems of conventional methods. As a pachinko machine hammer tip component that eliminates the problem, its practical value is extremely large. be.
