Ordinary golf ball is a structure that covers the surface of the urethane cover the core so formed so deep that the overall strength is not reduced.

Of course, in consideration of the fact that the dimensional variation of the dimple is caused in the course of the grinding process after the molding of the cover in the manufacturing of the golf ball, the above-mentioned dimensions can each allow 1% error.

The arranging of the diameter of the three dimples and the diameter of the four dimples formed the diameter of the three dimples and the one of the peanut-shaped dimples in the pentagonal body 100 formed in the golf ball of the present invention flows at the time of hitting. This is to facilitate the formation of turbulent flow, which is less affected by the physical conditions of the air, to favor the initial designed flight characteristics.

In addition, it is preferable that the area of the fourth dimple 305 constituting the triangular body 200 is 1.24%, and the volume thereof is 9.14 mm3.

In addition, the fourth dimple 305 is preferably formed with a diameter of 3 or more and less than 4.8 and is formed to a depth of 0.16mm to 0.18mmm.

Ordinary golf ball is a structure that covers the surface of the urethane cover the core so formed so deep that the overall strength is not reduced.

Of course, in consideration of the fact that the dimensional variation of the dimple is caused in the course of the grinding process after the molding of the cover in the manufacturing of the golf ball, the above-mentioned dimensions can each allow 1% error.

In the detailed configuration of the present invention, twenty-one dimples are formed in each pentagonal body 100 and twenty dimples are formed in each triangular body 200, and a total of 372 dimples are provided.

12 first dimples 301, 60 second dimples 302, 60 dimples 303 of the peanut shape, 120 third dimples 304, and the fourth dimples ( 305 is composed of 120 to form a total of 372 dimples.

As an example of the golf ball design of the present invention, if the area of the dimple formed in one piece of the pentagonal body 100 is 5.08%, the total area of the golf ball occupies 60.96% of the total surface area of the golf ball.

If the area of the dimples formed in one piece of the triangular body 200 is 1.24%, the total size is 20 pieces, which occupies 24.8% of the total surface area of the golf ball.

When describing the volume conditions for determining the flight time and ballistic height (ie, flying distance) of the golf ball, a volume of 39.14㎣ is formed in one piece of the pentagonal body 20 to form a volume of 469.68㎣ for a total of 12 pieces. , By forming a volume of 9.14 체 within one piece of the triangular body 200 to form a volume of 182.8㎣ for a total of 20 pieces.

This is to maintain the proper ball and volume when flying the ball to maintain the proper ball with the area according to the size of the golf ball, that is, the thickness of the cover, the properties of the inner core, and the volume. The dimple of the golf ball according to the detailed configuration of the present invention described above satisfies the above condition because the dimple area of 85.8% and the volume of 652.48 mm3 are formed in the whole sphere. If the area or volume of the dimple is less than the set value, the turbulence function is weakened, making it difficult to fly stably. If the set value is exceeded, the complexity of the manufacturing process is increased compared to the improved function.

Golf ball having a dimple structure according to the present invention has a perfect symmetrical structure in spherical shape to implement a feature that has a high reliability of turbulence formation when the ball goes straight while having a consistent straight direction.

Of course, in the application of actual mass production, the size of dimples and peanut-shaped dimples and the depths of dimples and peanut-shaped dimples are varied according to the properties of the raw materials, thereby changing the characteristics of the ball distance, rotational speed when hitting, and height of trajectory. can do.
