Description

GOLF BALL}

The present invention relates to a golf ball, a feature of the present invention is the degree of elasticity, that is, the modulus of elasticity that the golf ball changes under various ballistics without changing the standard (diameter and material) of the core is called a ballistic in the present invention. It is about golf ball which we could make with.

In general, the golf ball is made of a rubber core (Core) and the outer layer covering the core is formed of two or three or more, the core determines the trajectory with the outer layer surrounding the core.

Of course, the dimple formed on the outer surface of the golf ball is also one of the factors affecting the ballistic trajectory of the golf ball to improve turbulence by forming turbulence during the flight process, but various factors affecting the trajectory including the dimple Among them, the core and the outer layer surrounding the core are the most important factors affecting the trajectory.

In particular, the core of the structure, that is, the material and diameter mainly affect the weight, repulsion and resilience of the golf ball and determine the trajectory as the largest factor for determining the trajectory, thereby determining the trajectory.

In this regard, various developments and researches related to ballistics of golf balls have been made.

Korean Utility Model Publication No. 20-2000-0000671 includes at least two kinds of fluids having different specific gravity inside the protective film and not being mixed with each other, and the eccentric core and the cavity move the fluid to increase the eccentric force. It is separated by the bulkhead, which is separated by the bulkhead, and a hole for fluid movement in the bulkhead is formed to help the downward movement of the center of gravity. It is.

Republic of Korea Patent Publication No. 10-0726802 has a hole is formed from one surface of the golf ball penetrating the other surface, the cross-sectional area size of the hole is the golf ball is formed smaller than the central portion of the hole than one side or the other surface distance of the golf ball And a golf ball with a hole to increase accuracy and accuracy.

Republic of Korea Patent Publication No. 10-1998-033344 consists of a cavity center formed from a material selected from the group consisting of rubber, thermoplastic resins and mixtures thereof, at least one core rubber layer formed on the cavity center and the skin formed on the core rubber layer There is a hollow golf ball showing excellent durability and showing a small impact and having an excellent shot-foot without sacrificing flight performance.

In addition, the Republic of Korea Patent Publication No. 10-2005-0112505 is formed by the core space inside the golf ball to fill the space with a liquid liquid, the golf ball is not rolled well due to the swelling of the liquid liquid, the golfer is putting wrong A golf ball for putting practice is provided.

In addition, the Republic of Korea Patent Publication No. 10-2007-0093342 is formed in a portion of the surface of the sphere and the groove (Groove) of the net shape having a width and depth is formed to have a smaller air resistance than a golf ball dimple formed on the surface A golf ball has been published with improved flying distance and accurate orientation.

In particular, Patent Document 1 (Korean Patent Laid-Open Publication No. 10-2002-0007836) is provided on the outer circumferential surface of a golf ball when the golf ball is hit by installing a plurality of reinforcing members radially from the outer circumference to the center of the golf ball. The force is concentrated in the center of the golf ball to generate a strong repulsive force and prevent the deformation of the golf ball is published for a golf ball that can be extended.

The golf ball disclosed in Patent Document 1 forms a reinforcing member made of steel or the like radially in the outer circumferential direction from the inner circumference of the inner core, and when the golf ball strikes the force applied to the outer circumferential surface of the golf ball By generating strong repulsion force and preventing the golf ball deformation, it is possible to extend the distance.

That is, in the golf ball formed with a reinforcing member in the golf ball, the golf ball of the invention is modified in its shape at the site where it collides with the club head when hitting the club during the swing because a plurality of reinforcing members are inserted in the outer peripheral surface of the core This minimizes air resistance by preventing deformation of the area impacting the club head, thereby extending the flying distance.

In addition, when the golf ball hit the club head is deformed golf ball formed the reinforcing member is increased resistance to air and the flight distance due to the time delay until the golf ball emerges by the repulsive force and repulsive force at impact (Impact) In order to solve the relative shortening, the outer peripheral surface of the core is reinforced with steel or the like to prevent the deformation of the core and the shape of the impact portion of the club head so as not to deform the resistance to air to increase the flying distance.

However, the golf ball formed with the reinforcing member is a result of reducing the repulsion force and the repulsive force due to the steel or the like formed on the outer circumferential surface of the inner core, resulting in further shortening the flying distance, and also the weight of the golf ball due to the internal reinforcing member This becomes heavy.
