Description

[Detailed explanation of the idea] [Industrial application field] The present invention relates to a golf ball that emits light.

[Prior Art] Due to the overheating golf boom in recent years, the so-called golfing population is rapidly increasing, but in Japan, which has a small land area, it is difficult to increase the number of golf courses. This trend is particularly noticeable in the suburbs of large cities, where golf courses are filled with golfers on holidays. As a result, there are times when you have to start while it's still dark, and times where you have to start late and play after sunset. This situation is most noticeable in autumn and winter, where the sun sets early, and in the Tohoku and Hokkaido regions, where the sun sets early.

When playing in such twilight or darkness, even if there is lighting equipment, it is difficult to follow the ball's trajectory, and it is possible to lose track of its destination (fall, stop position) and end up losing the ball. There is still time. Therefore, a ball with fluorescent paint coated on its surface was devised. However, fluorescent paint does not emit light unless it receives light from the outside, so
There wasn't enough light.

[Problems to be Solved by the Invention] Therefore, the present invention provides a luminous golf ball that emits light by itself without being exposed to external light, and the amount of light is sufficient to follow the trajectory.

[Means for Solving the Problems] In order to solve the above problems, the present invention provides a golf ball with a central hole penetrating through the center thereof, and a small hole penetrating through the center of the golf ball with the above-mentioned small hole penetrating through the center of the golf ball. Two or more holes are drilled symmetrically around the center hole,
Translucent synthetic resin was press-fitted into the small holes, reaching the peripheral wall of the center hole from each opening thereof, and a light emitting body was inserted into and out of the center hole.

[Function] According to the present invention having the above configuration, a light emitter that emits light by itself is inserted into the golf ball, so that the light is radiated to the outside of the golf ball from the end face of the light emitter and the end face of the translucent synthetic resin. . Therefore, after the ball is hit, it flies while creating various light patterns according to its rotation, and even after it falls or stops, the radial light is scattered, so you will never lose sight of it.

[Example] Hereinafter, an example of the present invention will be described in detail based on the accompanying drawings. In addition, FIG. 1 is a perspective view of the golf ball of this example, FIG. 2 is a front view of the same example, FIG. 3 is a plan view of the same example, and FIG. 4 is a line A-A in FIG. 2. FIG.

In the figure, reference numeral 10 denotes a golf ball, and in this embodiment, a so-called large size two-piece ball is used. Reference numeral 12 indicates a center hole passing through the center of the golf ball 10, and 14a, 14b, and 14c each intersect the center hole 12 at an angle of 60°, and each form an angle of 120°. These are small holes that pass through the center of the golf ball 10 in an intersecting manner. The diameter of the center hole 12 is 4.5 mm, the small hole 14a,
The diameter of 14b and 14c is preferably 5 mm.

Reference numeral 16 denotes a psyllium in which capsules made of hard transparent synthetic resin are enclosed in a soft transparent synthetic resin, and psyllium liquid is sealed in each capsule.
The outer diameter of the cylinder is approximately the same as or slightly smaller than the inner diameter of the center hole 12. When the capsule is broken, the liquid in the capsule and the liquid between the capsule and the tube mix, causing a chemical reaction that takes several hours.
It is a chemical light that emits light for over 10 hours. Its colors include red, blue, green, etc.

Reference numeral 18 denotes a transparent acrylic resin 18 that is inserted from the respective openings of the small holes 14a, 14b, and 14c to the peripheral wall of the center hole 12. This acrylic resin 18
are glued so that they do not come off through the small holes 14a, 14b, and 14c. In this golf ball 10, the center hole 12 has the sirium 16 and the small hole 1.
The balance is maintained with acrylic resin 18 inserted into 4a, 14b, and 14c.

Next, a method of using the golf ball 10 having the above configuration will be explained. Sirium 16 is
Immediately before use, the golf ball 10 is inserted into the center hole 12, and just before insertion, it is bent from the center and the capsule inside is broken. The sirium 16 now starts emitting light, and when it is inserted into the center hole 12, it is guided by its both end faces and the acrylic resin 18, and the light is diffused to the outside from each end face.

After playing, you can leave the sirium 16 as it is, but when you play again, remove the old sirium 16 that does not emit light.
Insert a new sirium 16.

Although the preferred embodiments of the present invention have been described above, various modifications can be made. An example of the change will be explained below.

In addition to the size of the golf ball in this embodiment, there is a small size golf ball, but either size may be used. Optical fiber may be used instead of the acrylic resin 18.

The center hole and the two small holes may be perpendicular to each other. A vinyl chloride pipe or the like may be inserted into the small hole so that the center of inertia coincides with the center of the ball. However, in this case, it became easier to slice and hook, and the flight distance became shorter and more variable. Furthermore, the lack of light made it easy to lose track of the trajectory of the ball.

Increasing the number of small holes or increasing their diameter will increase the amount of light, but the flight distance will be shorter, the balance will be worse, and it will be easier to slice and hook. When the number of small holes was reduced or the diameter was reduced, the amount of light became insufficient and the balance deteriorated.

[Effects of the Invention] As is clear from the above explanation, according to the luminescent golf ball of the present invention, the ball can be tracked even under illumination during a night game or in the dark. Moreover, compared to a regular golf ball, the ball loses less distance and flies straight without losing its balance. Also, it can be used repeatedly by changing the sirium.
