Description

A putter configured to measure an inclination angle of a green gradient,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a putter, and more particularly, to a putter that uses a shaft to read a tilt angle of a green, The present invention relates to a putter configured to be able to read green readings more accurately and to measure a green inclination angle so as to reduce the number of teeth.

In general, golf is a set of eighteen courses consisting of four par, four par, four ten par, and five par five, namely, when a ball is hit by a golf club with a golf club of 72, and the ball is put in a hole cup, In the event of an increase in the number of strokes, it is an athletic event that reduces the number of strokes by using the word over.

The number of golf clubs to be used at this time is not to exceed 14, and the putter has the most number of bats, 36 of the 18 courses, and the putter in golf plays the most important role.

In other words, par 3 is a golf ball that matches the distance, putting up the green at once, putting it in a small circular hole cup of 108mm by two putts, par 4, 2 and par 5, And putting it on the green and placing it in the hole cup with two putts.

Therefore, the other golf clubs are selected according to the distance, and only the distance will be played. The ball will fly from the ground, so do not pay much attention to the inclination angle to the hole cup. Since the ball must be rolled from the green to enter the hole cup, the importance of the putter is emerging because it determines the direction of the hole in the direction of the hole so that the ball can enter the hole cup.

Recently plum bobbing technique, which is popular among famous golfers, is firing.

This technique is a method of measuring the direction in which the hole cup is inclined by aligning the ball and the hole cup in a straight line after the putter is set up vertically using the shaft of the putter.

However, there is a problem that it is difficult to find the center of the putter in the currently used putter.

For example, the putter shown in Figs. 1 and 2 is mainly used as a putter provided conventionally.

However, there is a big difference in the shape of the head for each company, but two types of shafts are used.

An example of this is shown in the accompanying figures 1 and 2.

The putter 20 includes a head portion 11 of a putter having various shapes in order to strike the ball and a grip portion 12 made of a rubber material for excellent grip feeling when gripping by hand, And a shaft 13 for connecting the shaft 12 with each other.

The shaft 13 connects the grip portion 12 and the head portion 11 while setting the length of the putter and the center of gravity is positioned on one side of the head so that the head portion 11 is perpendicular to the ground, Or a connection part of a serpentine shape 15 inclined at an inclined surface on the head part.

In addition, the shaft 13 has an inclined surface having a larger diameter toward the grip portion 12.

However, in order to perform line reading using a conventional putter having the above structure, the grip portion 12 is grasped by the thumb and forefinger, and the head portion 11 is directed to the ground so that the shaft and the hole cup are aligned in a straight line, You are looking at the line.

In this case, the shaft 13 can not be maintained in a vertical state due to the weight of the head portion 11, and the weight of the head portion is inclined in a heavy direction, and the line can not be read.

Even if the head portion is held long by the grip portion and the shaft is linearly formed, the shaft itself is inclined so that the correct line reading is impossible. Japanese Patent Application Laid-Open No. 10-2010-0059091, and Japanese Patent Application Laid-Open No. 2000-237354 as a putter used outside the country.

Japanese Unexamined Patent Application Publication No. 2000-237354 discloses a structure in which a shaft is formed in an upper light-tight shape, and a scale made of a circular tube is formed on one side of a shaft on the upper side of the shaft.

However, a putter with this structure is a putter that can not be used because it is contrary to Article 4 of the golf rules.

The putter is also intended to strike the putter face (strike face) in a straight line perpendicular to the direction in which it is intended to be sent.

However, when the protruding structure is attached, the center will be twisted so that it can not strike the ball in a linear direction.

Therefore, the putter of the Japanese Laid-open Patent Publication is a disabled putter in the regular hole and at the same time the state of the green line is known, but there is a defect that the putter can not hit in a desired direction.

Korean Patent Application Publication No. 10-2010-0059091 discloses that a laser is applied to the handle of the putter to display the straightness distance between the ball and the hole cup. However, this invention is also a putter that is not in accordance with the golf regulations, You can display the distance of the straight line to the direction you want to send with the laser light, but you can not know the degree of the green's inclination, so you have to depend on the eyes of the person using the putter.

However, human eyes are totally different from each other, and depending on the surrounding environment, optical illusions are caused, which can be mistaken for the slope of the green, which makes it impossible to put the correct putter.

It is an object of the present invention to provide a putter which can accurately read a golf putter without violating the golf regulations.

Another object of the present invention is to find an accurate center regardless of the center of gravity of the head of the putter.

Another object of the present invention is to make the shaft of the putter have the same diameter so as to eliminate the error caused by the inclination angle of the conventional putter whose diameter becomes smaller toward the bottom, thereby enabling a more accurate green reading.

In order to accomplish the above object, the present invention provides a putter comprising a head portion of a putter having various shapes for hitting a ball, a grip portion made of rubber for gripping by hand, and a shaft connecting the head portion and the grip portion, The head portion is provided with a bent portion or a shaft so as to be positioned at one side of the head so that the center of gravity is positioned at one side of the head so as to set the length of the putter perpendicularly to the ground while connecting the grip portion and the head portion, The shaft of the putter is constituted by a tubular body having a diameter equal to the diameter of the shaft of the remaining portion except for the portion connected to the head portion and a central axis which is changed in accordance with the weight of the head portion is located at the upper side portion of the shaft, The grip portion The present invention relates to a putter that can accurately read a green image by means of a plumb-bobbing technique by having a display portion so as to locate a position where a shaft is vertically positioned while being lightly gripped by a hand.

Further, the putter of the present invention may further comprise a horizontal unit so that the head part can be seen whether the head part is laid horizontally on the ground.

At this time, the leveling unit should be positioned inside the shaft and positioned at the lower end of the display unit so that the angle of the eye at the time of putting can watch the head of the putter.

In the present invention, the display unit may be constituted by stickers whose vertical lines are arranged at even intervals, and the stickers are positioned above the shaft, so that the user can recognize the vertical lines corresponding to the centers of the positions of the display units. .

In the present invention, the display unit can achieve the above object by using a sticker having one vertical line to enable green reading using a vertical line at all times in accordance with the center of gravity.

The display unit of the present invention can achieve the above object by configuring the shaft so that the vertical line of the engraved or embossed line coincides with the center of gravity of the shaft.

It is preferable that the horizontal unit in the present invention is built in the shaft so as not to protrude out of the body of the shaft.

According to the present invention, accurate center is detected by the display unit, and central deviation due to the weight of the head is not caused, so that accurate green reading is possible when the green is read by the plumb-bobbing technique.

The present invention has the effect of correcting green reading by eliminating deviations in reading a line by a plumb-bobbing technique with a conventional shaft in which the diameter of the shaft is reduced from the conventional grip portion to the head portion.

The present invention has the effect of making it possible to know whether the head unit is maintained in a horizontal state by constituting a horizontal unit so that the impact force applied to the ball can be accurately transmitted to the ball.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

In order to accomplish the above object, the present invention provides a golf club head comprising a head portion 11 having various shapes in order to hit the ball, a grip portion 12 made of rubber for gripping by hand, and a head portion 11 and a grip portion 12 A known putter made up of a shaft 13 for making

The length of the putter 20 is set while connecting the grip portion 12 and the head portion 11 so that the center of gravity is positioned at one side of the head portion 11 so that the head portion 11 stands upright on the ground surface. (14), or in the form of a sloped surface (15) on the head part,

The shaft 13 of the putter is composed of a shaft 23 having a diameter equal to the diameter of the shaft corresponding to the remaining portion except for the portion connected to the head portion 11 and the head portion 11 11), and the display unit (30) is provided so as to be able to accurately read the green image by the plumb-bobbing technique regardless of the shape of the head part (11) .

The display unit 30 may be provided with various types of display units 30 as shown in FIG. 5A. A plurality of vertical lines 32 having a predetermined length are formed at predetermined intervals on the sticker 31, The head portion 11 is fixed to the shaft 23 and the center position is grasped so that a vertical line 32 is formed on the portion corresponding to the center, (32) may be positioned.

6 and 7, the display unit 30 is provided with a straight line groove 34 formed by embossing lines 33 or engraved lines as shown in Figs. 6 and 7, and when the head unit 11 is fixed, The object of the present invention can be achieved even if the projecting line 33 or the groove line 34 is aligned with the center.

In this case, the center of gravity can be adjusted by vertically rotating a wall or a putter assembled with other weights so that the straight shaft 23 is aligned with a vertical line such as a wall surface, .

If a plurality of vertical lines 32 displayed on the sticker 31 are composed of different colors or numbers are written on the vertical lines, it is possible to read a putting line of a green easily by finding a color or a number without centering each time of use.

Further, the putter 20 of the present invention can further constitute a horizontal machine 50 so as to know whether the head part 11 is horizontally laid on the ground.

At this time, the horizontal unit 50 is preferably positioned between the display unit 30 of the shaft 23 and the head unit 11.

The reason why the leveling unit 50 is positioned at the lower end of the display unit 30 is that it should be positioned at the lower end of the display unit 30 so that the angle of the eyes at the time of putting can easily identify the horizontal state while watching the head portion of the putter.

According to the present invention configured as described above, in order to insert a ball into a hole cup by putting while putting the ball on the fairway in a state where the golfer puts the ball on the green, the state of the green, that is, The ball must be rolled to a position higher than the hole cup according to the degree of inclination. In this case, the present invention judges which portion of the hole cup is higher in the left side and higher in the right side, and hits the ball to the left or right side.

However, eyes often cause optical illusions depending on the surrounding scenery, so that accurate measurements can not be made frequently.

In this case, the present invention locates the center in advance and places the selected display portion on the front of the eye, and when the shaft () is placed, the shaft is in a straight line state, and the vertical state is maintained.

At this time, if you see the shaft, ball and the hole in a straight line, the hole will be moved to the left or right according to the slope of the green.

Therefore, when the direction in which the hole cup appears to be low is higher, it becomes possible to know the degree of inclination depending on how much the ball is moved.

The striker can strike the ball in the direction of the green with the width of the slope so that it can put the ball into the hole cup more accurately, thereby reducing the number of his own batting.

In addition, according to the present invention, by using a horizontal ruler to adjust the putter to a horizontal state with the green, the force transmitted to the ball can be accurately hit at the center of the ball without having a spin, You can enjoy it.

The above description is only an example for implementing a golf putter, and the present invention is not limited to the above-described embodiment.
