Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a hitting device for a pachinko machine that launches a pachinko ball toward a game board surface.
[0002]
[Prior art]
A hitting body formed of an elastic material is generally attached to the tip of a metal hitting spear even if there is a difference in driving method.
The hitting body absorbs a direct impact on the spear and effectively repels the ball to the game board surface by the repulsive force of the material, and is an indispensable element in the launching device.
[0003]
The hitting body used in the past is made of a soft synthetic resin with elasticity and made into a cap shape, and is attached so as to cover the tip of the spear. The striking part rushes to the starting end of the guide rail and ejects a pachinko ball waiting on this.
[0004]
FIG. 4 shows the conventional hitting body in a solenoid hitting device. A cap-shaped impacting body 20 formed of a soft synthetic resin has an annular convex groove 21 formed on the inner peripheral surface portion, and an annular concave groove formed on the peripheral surface of the plunger 23 of the solenoid 22 serving as an impact rod. The protrusions 21 are fitted to 24 and attached integrally.
[0005]
The striking body 20 is attached to the tip of the plunger 23 by forcibly expanding it using elasticity, and has a structure in which the convex strip 21 is fitted into the concave groove 24 by a restoring force to prevent it from being removed. Sometimes, the top hitting portion 25 receives the ball and is compressed to increase the repulsive force and cooperate with the pushing of the plunger 23 to eject the ball.
[0006]
[Problems to be solved by the invention]
This conventional striking body is easy to attach to the plunger that becomes the heel, and in use, it is in close contact with the tip by the elastic restoring force to obtain a stable mounting state, but the material is an elastic body and is deformed at the time of striking. Since it is premised, there may be a position shift with respect to the tip of the heel, and there is a drawback that causes uneven firing.
[0007]
Needless to say, the ball striking device launches as many as 100 pachinko balls per minute when in use, and it must ensure a stable firing distance each time according to the player's operation. Therefore, causing unevenness of launch not only gives off a foul ball, but also detracts from the player's willingness to play. In this sense, the displacement of the impacting body relative to the tip of the heel is a major improvement issue.
[0008]
The positional displacement of the impacting body occurs at the time of a collision with a ball, and the impacting body that is stably in close contact with the constant restoring force and ensures the integrity of the impacting object is deformed by the distortion generated at the time of the impact and It is thought that this occurs due to the loss of adhesiveness and backlash. However, this distortion is a characteristic of the elastic body as described above and cannot be completely suppressed.
[0009]
In this situation, the present invention eliminates misalignment with the tip of the heel and ensures stable firing of the ball while ensuring an appropriate firing force without suppressing the distortion at impact, that is, the repulsive force based on elasticity. In particular, the present invention aims at integrating the center position of the striking body with the center position of the striking body when striking the striking body. It is an object of the present invention to provide a hitting device for a pachinko machine that secures the center position without being affected by the generated distortion so that a constant hitting state can be obtained.
[0010]
[Means for Solving the Problems]
The present invention has been made on the basis of the above-mentioned object, and is characterized in that a concave hole is drilled from the end surface portion along the axial center to the tip portion of the hitting ball in the hitting ball launcher, while the tip of the hitting rod is provided. The impacting body to be mounted on the part is formed into a cap shape by an elastic material, and an engaging convex part is projected from the center of the inner surface of the impacting part, and the engaging part is inserted when the impacting body is attached to the tip of the impacting rod. It is an object of the present invention to provide a hitting ball launcher for a pachinko machine characterized in that a convex part is fitted into the concave hole and integrally mounted.
[0011]
Further, the present invention provides a pachinko machine characterized in that, in the hitting ball launching device, the concave hole of the striking gutter has a bottom, and the engaging convex portion of the striking body fitted to this has a tip abutting on the bottom. The object is to provide a ball striking device.
[0012]
Further, the present invention is the ball hitting device according to the present invention, wherein an annular retaining groove is formed on the outer peripheral surface of the tip of the hitting gutter, and an annular engaging ridge is formed on the inner peripheral surface of the cap-shaped hitting body. It is an object of the present invention to provide a hitting device for hitting a pachinko machine, which is raised and fitted and stopped using the elasticity of the hitting body.
Next, embodiments illustrating the present invention will be described.
[0013]
Embodiment
【Example】
FIG. 1 is a partially cutaway front view showing a use state of a hitting ball launching apparatus according to the present invention, FIG. 2 is an enlarged front view of the hitting ball launching apparatus, and FIG. It is an enlarged front view which made the principal part the cross section.
In the drawings, 1 is a front frame covering the front surface of the pachinko machine, 2 is a glass metal frame for containing glass mounted on the front frame, and 3 is a prize ball tray that is arranged under the glass metal frame 2. Reference numeral 4 denotes a grip for operation of the hit ball launching device 5, and reference numeral 6 denotes a prize ball lower plate.
[0014]
In this embodiment, the hitting ball launching device 5 is a device using a solenoid. Here, a plunger 8 serving as a hitting rod is mainly composed of a solenoid 7 serving as a driving force, and when the plunger 8 is in a demagnetized state, it is returned to a retracted position. The spring 9 is configured as a main element.
[0015]
The hitting ball launching device 5 is set on a base 10 serving as a mounting substrate when assembled in a pachinko machine, and the leading end of a guide rail 11 for hitting a ball hitting the tip of the plunger 8, that is, the tip of the hitting rod 8, extends from the base 10. It faces the part 11a.
[0016]
In the figure, reference numeral 12 denotes an impacting body attached to the tip of the impacting saddle 8.
The impacting body 12 is formed of a material having elasticity, such as a soft synthetic resin having elasticity, and being strong and durable, and polyurethane rubber is selected here.
[0017]
This striking body 12 is formed in a cap shape as shown in FIG. 3, and an annular ridge 13 is raised at an intermediate portion of the inner peripheral surface, and a hollow portion is formed at the center of the inner surface of the striking portion 14 which is a top portion. A cylindrical engaging convex portion 15 is projected along the center of the portion.
[0018]
The cap-shaped striking body 12 is mounted so as to cover the front end portion of the striking gutter 8, and an annular retaining groove for engaging the convex strip 13 at the front end portion of the gutter 8. 16 is formed over the entire circumference of the outer peripheral surface, and a concave hole 17 into which the engaging convex portion 15 is fitted is formed in the central portion of the distal end surface.
[0019]
The striking body 12 is formed in a cylindrical cap shape so as to be in close contact with the distal end portion of the rod 8 and has an inner diameter slightly smaller than the outer diameter of the distal end portion, and an elastic restoring force. Further, the protrusion 13 is fitted to the inner surface of the recessed groove for retaining or is formed to be slightly larger and contracted.
[0020]
Further, the engaging convex portion 15 is formed to be slightly thicker than the concave hole 17 at the front end portion of the heel and to reach the bottom of the hole, and when the impacting body is mounted, the engaging convex portion 15 is forcibly pushed into the concave hole 17 and closely adhered. I have to do it.
[0021]
The striking body 12 constructed as described above is fitted into the tip of the flange 8 while being expanded using the elasticity of the material, and the engaging projection 15 is inserted into the recess 17 and the projection 13 is inserted into the retaining recess 16. Each of them is attached and attached, and after the attachment, they are brought into close contact by a restoring force and integrated.
[0022]
The solenoid 7 is assembled to the main body of the pachinko machine via the base 10 and fixed together with the guide rail 11 at a fixed position.
When the ball hitting device 5 is in a normal state, the ball 9 is demagnetized and the striking rod (plunger) 8 is placed in the retracted position by the spring 9, and the tip portion is railed while compressing the spring 9 when firing with excitation. The pachinko ball which protrudes to the start end part 11a of 11 and waits for this is ejected.
[0023]
When hitting the hit ball, the hitting body 12 hits the hitting portion 14 against the ball, and fires by applying the elastic repulsive force of the portion in conjunction with the pushing out of the spear 8.
At this time, the impacting body 12 may be deformed and distorted, and lacks integrity with the tip of the heel. However, the engaging protrusion 15 projecting from the center of the inner surface of the striking portion 14 is formed in the center of the heel tip. Since it fits into the concave hole 17 and always stays at a fixed position with respect to the tip of the heel, it is possible to catch the ball at a fixed position of the striking portion 14 and thus perform a constant launch.
[0024]
In this embodiment, since the tip of the engaging projection 15 is in contact with the bottom of the recess 17 at the tip of the saddle, it retracts unnecessarily when the striking portion 14 is compressed during striking. It is avoided that the hitting portion inner surface is damaged at the edge of 17.
Of course, the main purpose of the engaging convex portion 15 is to secure the center position and prevent the displacement of the impacting body 12, so even if it has a length that does not reach the bottom of the concave hole 17. It goes without saying that
[0025]
The present invention is constructed and used as described above. The impacting body 12 is fatigued by use, and when damaged, it can be forcibly peeled off while expanding using elasticity, and the impacting body to be replaced is described above. Thus, if it is fitted so as to be pressed toward the tip of the heel, it can be easily mounted.
[0026]
Of course, although the solenoid type launching device has been described in the embodiment, the driving force is not limited to this, and the present invention can be applied to all launching devices having a striking gutter. It can be used effectively and expected to be effective.
[0027]
【The invention's effect】
As described above with reference to the embodiments of the present invention, the impacting body to be mounted on the tip of the striking kite is fitted with the engaging convex portion provided on the striking tip in the concave hole of the tip of the scissors so that the positional deviation at the time of striking Therefore, it is possible to always ensure hitting at a certain portion, and thus it is possible to stably hit the hit ball.
[0028]
Further, according to the present invention, not only the striking body is placed on the tip of the heel but also the engaging convex portion is fitted into the concave hole of the heel tip so that a stable fixation can be obtained and a robust mounting can be expected.
[0029]
Furthermore, the present invention further increases the hitting point for the pachinko ball due to the increase of the hitting area of the hitting portion as the engaging convex portion is provided on the inner surface of the hitting portion of the hitting body, and there is a slight positional deviation. Even if it occurs, a stable launch can always be expected.
