Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a golf ball having a putting guide line and a rotation guide line,

The present invention relates to a golf ball having a putting guide line and a rotation guide line and a method of manufacturing the same. More particularly, the present invention relates to a putting guide line for guiding a putting direction having a good straight- A golf ball having a putting guide line and a rotation guide line formed on the outer surface of the golf ball so as to guide the batting direction in which the rotation axis is not changed during the golf course, And a method for producing the same.

Generally, when driving a driver's shot or iron shot in a golf game, in order to improve the distance of the golf ball, the attitude of the player and the hit point of the golf ball are important. In particular, if the golf ball is struck downward by a predetermined distance with respect to the center of the golf ball, the golf ball reversely rotates, and the upward force acts in a direction perpendicular to the direction of travel, thereby allowing the golfer to move forward.

This principle is particularly recognized for players to accurately grasp the center of gravity of the golf ball and strike it in order to allow the golf ball to fly away in a desired direction, especially when applied to a golf game.

Here, the golf ball has a diameter larger than 1.68 inches (42.67 mm) and a weight smaller than 1.62 ounces (45.93 g), and is used in a golf game. As shown in FIG. 1, (2) and a cover (3) surrounding the core (2).

However, since a golf ball produced in large quantities has a different center of gravity and there may be a difference in internal mass, it is necessary to find the center of gravity of the golf ball and set the upper point of the center of gravity as the center axis of rotation Is a very difficult situation.

In other words, since the core of the golf ball is heavier than the cover, the core is not positioned in the center as shown in FIG. 1, and when the golf ball is biased toward one side, the ball becomes heavy and light and unbalanced. The golf ball must be bent toward the heavy side.

Recently, a putting line is arbitrarily displayed on the outer circumference of a golf ball. However, since the accuracy of the line is lower than the accuracy of the putting line, a problem that causes an inaccurate shot is caused. It is a fact that it works.

In the following description, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

In the following description of the present invention, it is to be understood that the terminology used herein is for the purpose of describing the exemplary embodiments of the present invention and is not intended to limit the scope of the present invention. May be exaggerated for clarity and convenience of explanation, and the embodiments described in the present specification and the constitutions shown in the drawings are merely the most preferred embodiments of the present invention, and not all of the technical ideas of the present invention It is to be understood that various equivalents and modifications may be substituted for those at the time of the present application.

FIG. 5 is a schematic cross-sectional view of a golf ball according to an embodiment of the present invention.

First, the golf ball according to the present invention includes a putting guide line for guiding the putting guide line so as to secure the best straightness according to putting, and a rotation guide line for minimizing the change of the rotation axis when flying and blowing, So that it can be selectively utilized according to the situation of golf.

The resistance generated from a fast-flying golf ball has frictional resistance from the front side and shape resistance from the back side. The frictional resistance is a resistance generated in the golf ball due to the friction between the air and the golf ball, and the shape resistance is a resistance caused by the swirl of air generated in the rear of the golf ball when the golf ball is flying in the air.

In order to reduce the shape resistance, the shape resistance of the resistors serves as a main factor for lowering the trajectory and the flying distance of the golf ball. In order to reduce the shape resistance, a recessed groove called a dimple 11 having various shapes and numbers is formed on the outer surface of the golf ball. Respectively.

Since the golf ball having the dimples 11 formed therein is slower in the flow of air than the dimples 11 having no dimples, the area of the vortices or wakes occurring behind the golf ball is reduced, The shape resistance caused by pulling in the direction opposite to the direction is reduced.

Recently, in order to further increase the distance of the golf ball and to further improve the aerodynamic symmetry, various studies have been conducted on the arrangement of the dimples, the total number, various dimensions, the volume, and the shape.

In addition, a golf ball makes a core, and the cover is divided into two halves to be pressed on both sides. When looking closely, the joining line connecting the cover to the center of the ball is finely formed.

Golf using the golf ball described above is a game in which a golf ball is struck by a plurality of golf clips and put in a predetermined hole. To do this, a golf ball is put in a hole by putting or a golf ball is blown away .

In this case, when the golf ball is put in the hole by putting, when the golf ball is rolled, the weight distribution of the right and left is uniform on the basis of the putting guide line formed on the golf ball, 13 are positioned in the same line on the left and right sides with respect to the putting guide line 30.

That is, when the center of gravity indication point 20 of the golf ball is positioned on the putting guide line of the golf ball when the golf ball is hit, the center of gravity of the golf ball is not shifted to either side of the putting guide line So that it is possible to prevent the golf ball from rocking when the golf ball rotates and to ensure the straight rotation of the golf ball.

Therefore, in the present invention, the putting guide line 30 is formed on an arbitrary line where the center of gravity display point and the joining line are perpendicular to each other so that the joining line is symmetrically positioned on the left and right sides with respect to the putting guide line, So as to improve the straightness progression due to the impact.

In addition, when the golf ball is blown away, the rotation axis is changed due to the influence of the dimple formed on the outer surface of the golf ball and the center of gravity of the golf ball itself. In this case, , The rotation shaft which is severely changed causes a reduction in the primary distance, as well as a phenomenon of flying in an unexpected direction.

Therefore, in the present invention, an optimal rotation guide line is formed on the outer surface of the golf ball in a state in which the golf ball floats in the air and is rotated at a constant number of revolutions by providing an environment similar to an environment in which the golf ball flies in the air, It is possible to improve the flying distance when flying according to the blow.

As described above, the golf ball according to the present invention includes a putting guide line for guiding the ball to secure the best straightness at the time of putting, and a rotation guide line for guiding the position where the change of the rotation axis can be minimized when the ball is blown away So that the golf club can be selectively used according to the situation of golf.

In the golf ball 10 of the present invention, a plurality of dimples 11 and a bonding line 13 are formed on the outer surface of the golf ball. In the golf ball, A putting guide line 30 is formed on an arbitrary connecting line that vertically connects the center of gravity point 20 and the connecting line 13, A rotation guide line having the same direction as the rotation direction of the golf ball is formed on the outer surface of the golf ball rotated at a constant rotation axis when the ball is rotated, and the rotation guide line 40 is formed at the farthest point from the rotation axis .

The center of gravity display point 20 is formed on the outer surface of the golf ball so as to locate the center of gravity of the golf ball and recognize the position of the center.

In the present invention, brine having a specific gravity larger than that of water is used to display the gravity center display point 20 on the outer surface of the golf ball. When a golf ball is floated on brine, a part of the golf ball is exposed on the surface of the brine, Wherein the center of gravity mark is displayed at any of the exposed top point and the opposite point symmetrical to the top point thereof.

That is, the exposed top point where the center of gravity display point 20 is displayed is a point formed on the surface of the golf ball through a straight line passing through the center of gravity at the center of gravity of the golf ball.

The putting guide line 30 is formed on an arbitrary connecting line in which the center of gravity point 20 and the joining line 13 of the golf ball are perpendicular to each other and is formed by a marker or printed on an outer flat surface of a golf ball You will not be easily peeled off.

The putting guide line 30 displays a straight direction of the golf ball when the putting is easy to understand by the user, and the weight distribution of the right and left of the golf ball rolling on the green is made uniform so as to improve the straightness of the golf ball do.

Here, there may be a case where the center of gravity indication point 20 indicating the center of gravity of the golf ball is located at the joining line of the golf ball and at the pole, The putting guide line 30 may be formed so as to be perpendicular to the bonding line 13 and when the center of gravity indication point is located at the pole of the golf ball, It may be formed by selecting any one of the lines.

The center of gravity display point 20 may be positioned at the center of the putting guide line 30. [ That is, the putting guide line 30 is formed on an arbitrary line perpendicular to the bonding line 13 while passing through the center-of-gravity point 20.

Since the center of gravity is positioned at the center of the putting guide line 30 and the putting guide line is perpendicular to the joining line 13 as described above, So that it is possible to secure more effective straightness at the time of putting.

The rotation guide line 40 guiding the direction of the golf ball in which the rotation axis is not changed when the golf ball is blown by hitting the golf ball, After the ball is rotated, the outer surface is formed with a marking member.

At this time, as shown in FIG. 6, the air flowing into the air induction groove 63 rotates in a and a ', b, and b' directions for several seconds and gradually comes close to the air induction groove 63 And then the rotation axis of the golf ball becomes constant and rotates in the S direction which is the same direction as that of the air guide groove 63.

When the golf ball is rotated through the rotation means and rotated constantly in the S direction, a rotation guide line in the same direction as the rotation direction is formed on the outer surface of the golf ball through a separate marking member.

Here, the marking member 80 may form a rotation guide line 40 on the outer surface of the golf ball which is rotated by being floated by the air blowing device 70, and may be a spraying method, a laser marking method, There will be.

The rotation guide line 40 formed on the outer surface of the golf ball through the marking member 80 in the process of being rotated by the rotation means is formed at a position farthest from the rotation axis of the golf ball to be rotated.

That is, the rotation guide line 40 is formed at an intersection between a plane cut along the center of the golf ball at a right angle to the rotation axis of the golf ball and an index.

Meanwhile, it is preferable that the putting guide line 30 and the rotation guide line 40 formed on the outer surface of the golf ball are formed to have mutually different shapes. In case of putting on the green or blowing golf balls, So that the user can select the guide line that is appropriate for the user.

In the case where the putting guide line 30 and the rotation guide line 40 are formed to have the same rotation axis and the same direction, as shown in FIGS. 7 and 8, the putting guide line 30 and the rotation guide line 40 have different shapes, So that the user can recognize that the putting guide line and the rotation guiding line of the user have the same rotation direction.

The step of forming the center of gravity display point S10 is a step of forming a center of gravity mark on the outer surface of the golf ball indicating the center of gravity of the golf ball, It would be desirable to find the center of gravity of the golf ball prior to formation.

A center of gravity display point 20 is formed on the outer surface of the golf ball by looking at the center of gravity of the golf ball and then the bonding line 13 formed on the golf ball is identified.

In other words, the golf ball forms a spherical core as described above, and covers the core by pressing the cover in half by pressing the cover in half, wherein the joint line 13 is a line in which the covers of the hemispheres are joined to each other .

After the joint line is identified in the golf ball, a putting guide line 30 is formed which guides the putting shot on any line connected to the center of gravity marking point perpendicular to the joint line.

Here, the putting guide line 30 is formed on an arbitrary vertical line connecting the center of gravity display point and the joining line. When the gravity center indicating point is located at the joining line of the golf ball, the putting guide line 30 And the putting guide line (30) is arranged so as to be perpendicular to the bonding line, and when the center of gravity indication point is located at the pole of the golf ball, any one of a large number of lines perpendicular to the bonding line It may be preferable to select it.

Thus, if the putting guide line formed on the outer surface of the golf ball on the outer surface of the golf ball is perpendicular to the direction of travel of the golf ball, the putted golf ball is rotated along the putting guide line to contribute to accurate putting.
