Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a golf ball, and more particularly to a golf ball in which a pattern to be displayed on the spherical surface of the golf ball is formed with a groove and a fluorescent paint is applied to the inner surface of the groove.

[0002]

[Prior art and its problems]

 A golf ball has many dimples on its spherical surface in order to improve the flight distance. In general, initials, symbols or numbers are printed on the spherical surface provided with such dimples so that the golf balls of the respective athletes can be identified.

Further, a golf ball, which is a color ball in which the entire surface of the golf ball is colored, has also been used. A golf ball printed with such initials is an individual golf ball for use on the golf course, and in order to clearly distinguish it from the golf balls of other players, the initials etc. It was displayed by printing etc.

By the way, as a preparation for going out to a golf course, it is common practice to practice hitting. This batting practice is commonly referred to as leaving the ball, and its purpose is to confirm the feeling of the batting posture and the flight direction of the golf ball.

In order to carry out this batting practice, a dedicated golf training field (hereinafter referred to as a batting training field) is often used. This batting practice field is formed by stretching a ball-proof net with a side length of several tens of meters so that the whole structure becomes a substantially rectangular parallelepiped. Then, the golf ball can be driven to the other side from the striking space provided on one side in the ball-preventing net formed in the substantially rectangular parallelepiped, and the flight distance can be confirmed. Each facility is in place.

Since the golf ball used in the batting practice range cannot be collected during the batting practice, a golf ball lent at the batting practice field is generally used. An inexpensive one is used, which is formed only by ordinary dimples on the surface.

However, a golf ball having only dimples formed on such a surface is hit by one player from a single direction in practice in the above-mentioned batting practice field, and therefore, the ball cannot be hit by itself. I was confused with the hits of other players, and it became difficult to follow the whereabouts of the ball, which was a win. Also, especially in the practice at night, the golf ball is small even if the lighting equipment is fully equipped, so the player often loses sight of the direction of flight of the ball, making it difficult to practice effectively.

[0008] Therefore, as one of the measures for keeping track of the flight direction of a golf ball and the like, it is often the case that a powerful lighting facility that can illuminate a large practice field is provided to enhance the lighting. It was

However, there is a problem in that such strong lighting may damage the surrounding environment at night and the cost for lighting increases.

[0010]

[The purpose of the device]

 The present invention has been made in view of the above-mentioned conventional problems, and even if the lighting equipment in the driving range is not sufficient, the flight direction can be easily confirmed, and the manufacturing cost is low. An object of the present invention is to provide a golf ball that can be manufactured.

[0011]

[Key points of the device]

 According to the present invention, the object is to form a sphere of soft rubber, plastic, polyurethane foam, or other material, and to form a pattern over the entire spherical surface of the sphere by means of a groove, and to form a fluorescent light on the inner surface of the groove. It is achieved by providing a golf ball which is characterized by being coated with a paint.

【Example】

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. 1 (a) to 1 (g) are schematic orthographic views showing a first embodiment of a golf ball according to the present invention.

In FIGS. 1A to 1G, the golf ball 1 is formed to have substantially the same outer dimensions as a golf ball that is generally used. On the spherical surface of the golf ball 1, for example, a curved display pattern 2 (hereinafter simply referred to as pattern 2) formed by a groove is provided.

A fluorescent paint is applied to the inner surface of the pattern 2 so that the pattern 2 is displayed with the fluorescent paint. Therefore, when this pattern 2 is displayed with a fluorescent paint, it looks as if it was raised from the surface of the golf ball 1 because the pattern 2 glows during practice at night. Since the pattern 2 extends over the entire golf ball 1, it can be confirmed from any direction of the golf ball 1. Therefore, it is not necessary to apply the entire surface of the golf ball 1 with the fluorescent coating, and the cost is naturally lower than the case where the entire surface of the golf ball 1 is applied with the fluorescent coating.

This fluorescent paint can be colored in various colors with dyes such as xanthene dyes and basic dyes. For example, golf painted with a fluorescent paint of a different color from an adjacent player at a batting range. By using the ball, confusion with other players is less likely to occur, so you can easily check your own ball hitting direction.

In particular, by using the fluorescent paint, even if the lighting at the batting practice field is weak, it becomes easy to confirm the flight distance and the batting direction of the golf ball, and the cost for lighting at the batting practice field is suppressed. Will also be possible.

Then, as shown in FIG. 1A, the pattern 2 swells counterclockwise along the circular contour of the golf ball 1 when viewed from the front, crosses the approximate center of the circle to the right, and then the circular contour. It has a substantially S shape that swells in a clockwise direction.

The plan view shows a state in which the pattern 2 is displayed in a substantially lateral Ω shape that swells from the left side to the right side ((c) in the same figure). It shows that the parts extend from three directions toward the center of the circle at intervals of 60 ° ((e) in the same figure). When the pattern 2 is viewed from the back, the pattern 2 is symmetrical to the pattern 2 shown in the front view (the same figure (b)), and when the pattern 2 is viewed from the bottom, the pattern 2 is the pattern 2 shown in the plan view. It has a symmetrical shape (Fig. 2 (d)).

The patterns 2 shown in the left side view and the right side view are point-symmetric with respect to the center of the circle ((e) and (g) in the figure). The sectional view taken along the line A-A in the front view shows that the portion where the pattern 2 is formed is slightly recessed from the surface of the golf ball 1 to form a groove ((f) in the same figure). .

2 (a) to 2 (g) are schematic orthographic views showing a second embodiment of the golf ball according to the present invention. In FIGS. 1A to 1G, fluorescent paint is applied to the inner surface forming the pattern 2 appearing on the surface of the golf ball 1.

The pattern 2 of the golf ball 1 is formed in a zigzag shape similar to the arithmetic number “3” when viewed from the front. Therefore, the pattern 2 seen from the plane is almost the same as the pattern 2 seen from the front. The pattern 2 seen from the left side surface is shown as an arc shape on the upper, lower, left and right sides of the circular surface of the outline representing the spherical shape of the golf ball 1.

The cross-sectional view taken along the line AA in the front view shows a state in which two recesses are formed on the top, bottom, left, and right of the circular shape of the golf ball 1 to form the pattern 2. Has been done.

Further, the curve of the pattern 2 seen from the back surface is symmetrical with the pattern 2 seen from the front surface, and the pattern 2 on the bottom surface appears symmetrical with the pattern 2 on the plane. The pattern 2 seen from the right side surface is the same as the pattern that appears when the pattern 2 seen from the left side surface is rotated about 45 ° to the left or right.

3 (a) to 3 (g) are schematic orthographic views showing a third embodiment of the golf ball according to the present invention. In FIGS. 1A to 1G, fluorescent paint is applied to the inner surface forming the pattern 2 appearing on the surface of the golf ball 1.

The pattern 2 drawn on the golf ball 1 is formed into three wavy lines extending in a vertical direction when viewed from the front, and in FIG. 1 (a), the substantially central portions of these wavy lines are respectively formed. Is a curve that swells to the right. The wavy lines in the upper and lower parts sandwiching the wavy line in the central part are curved lines that swell to the left side, respectively, and the pattern 2 seen from the plane appears to be almost the same as the pattern 2 in the front view (FIG. (C)). .

The patterns 2 on the back surface and the bottom surface appear symmetrically with the patterns 2 on the front surface and the plane (FIGS. (B) and (d)). On the other hand, the pattern 2 seen from the left shows an annular curve that projects slightly in the vertical and horizontal directions (Fig. (E)). In addition, the pattern 2 from the right side is the same as the pattern that appears when the pattern 2 viewed from the left side is rotated about 45 ° to the left or right (Fig. (G)).

The cross-sectional view taken along the line AA in the front view shows a state in which eight recesses of the above-mentioned recess are shown around the circle ((f) of the same figure). 4 (a) to 4 (g) are schematic orthographic views showing a fourth embodiment of the golf ball according to the present invention.

In FIGS. 1A to 1G, fluorescent paint is applied to the inner surface forming the pattern 2 appearing on the surface of the golf ball 1. The pattern 2 seen from the front of the golf ball 1 is formed in a shape similar to the S-shape of the alphabet, and in the plan view is a substantially horizontal U-shape on the right side at the approximate center position of the circular shape of the golf ball. The bulging curve is shown ((a) and (c) in the same figure). The pattern 2 seen from the left side surface shows streak-shaped arcs at intervals of about 60 ° from the center point of the golf ball 1. The pattern 2 seen from the back and the bottom appears symmetrical to the pattern 2 seen from the front and the plane ((b) and (d) in the same figure), and the pattern 2 on the right side is the patterns 2 and 1 on the left side. It appears in the pattern 2 which is point-symmetrical at 80 ° (Fig. 2 (g)).

The sectional view taken along the line AA in the front view shows a state in which the six concave portions are shown around the circle ((f) of the same figure). The golf ball of the present invention shown in each of the above embodiments has, for example, a diameter of 41. It is formed into a sphere within the range of 15 mm to 42.67 mm and the weight of 25 g to 28 g. The material of the golf ball 1 is made of a uniform material such as soft rubber, plastic, and foamed polyurethane. Further, the surface layer is made of plastic, and the core is made of foamed polyurethane. It can also be formed.

Further, even if the golf ball 1 is practiced in a batting practice field where lighting is weak, the flight direction and flight distance of the golf ball 1 can be easily confirmed. The recess of the groove forming the pattern 2 prevents the flight distance from being extended due to the air resistance. Therefore, even when the golf ball 1 is fully shot with a golf club, the flight distance is not extended as compared with a conventional golf ball.

Further, since the pattern 2 formed on the golf ball 1 having the above-mentioned structure is formed in a groove shape slightly recessed from the surface of the golf ball 1, the pattern 2 is less likely to be chipped and less likely to be worn. Therefore, even if the pattern 2 is used for a long period of time, the degree of recognition by the pattern 2 does not decrease.

In addition to the pattern shown in the above embodiment, the pattern 2 may be any pattern as long as the pattern of the golf ball can be recognized in all directions. As the fluorescent paint to be applied to the inner surface of the golf ball, a single color of fluorescent paint may be used for one golf ball, or a plurality of colors of fluorescent paint may be used for one golf ball.

[0033]

[Effect of device]

 As described above in detail, according to the present invention, since the groove is formed with a pattern extending over the entire spherical surface of the golf ball, and the inner surface of the groove is coated with the fluorescent paint, it is possible to perform the illumination under weak illumination. It is now possible to obtain a golf ball that can confirm the flight direction and flight distance even in the competition.

Further, even if the lighting at the batting practice range is weak, it is possible to easily check the flight distance, the batting direction, etc. of the golf ball, so that it is possible to reduce the cost of lighting at the batting practice field.

[Correction content]

A fluorescent paint is applied to the inner surface of the pattern 2 so that the pattern 2 is displayed with the fluorescent paint. The fluorescent paint here refers to what is called a luminous paint or a phosphorescent paint , as is well known . Therefore, when this pattern 2 is displayed with a fluorescent paint, it looks as if it was raised from the surface of the golf ball 1 because the pattern 2 glows during practice at night. Since the pattern 2 extends over the entire golf ball 1, it can be confirmed from any direction of the golf ball 1. Therefore, it is not necessary to apply the entire surface of the golf ball 1 with the fluorescent coating, and the cost is naturally lower than the case where the entire surface of the golf ball 1 is applied with the fluorescent coating.
