Description

Putter {PUTTER}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a putter, and more particularly, to a putter that is adjustable such that a face of a head is opened or closed so that even if a user performs a pushing and pulling according to a specific habit, The present invention relates to a putter in which a hit golf ball can be straightened to a desired hole cup with an accurate direction by being configured to be capable of an angle change.

Golf clubs have drivers, woods, irons, wedges, and putters depending on their purpose. Among them, putters are the most important golf clubs that determine the score to be used on the green of the field. Used to insert.

As shown in Fig. 1, the putter includes a head 1 striking the ball, a shaft 2 having a predetermined length and swinging the head, and a shaft 2 fixed to the top of the shaft 2, (3) to maintain the basic shape of the golf club. The head 1 is formed in the form of a substantially rectangular or elliptical shape having a longitudinal direction before and after so as to accurately hit the ball.

The above putter putting is the most sensitive operation among the golf swing. If the golf club swings slightly or the angle deviates, the putting ball gets out of the hole cup. Therefore, golfers are making a lot of efforts to find their own putting movements and putters that fit their body.

In general, the swing trajectory of a golf putter has a swing (pull) and a pulling swing (push) by the user's own habits, the characteristics of the user, and the use of the ordinary wrist. Thus, It is often difficult to go straight to the hole and get out of the hole. Therefore, when most of the putter is practiced with one putter and the putter ball does not go straight to the hole cup and goes out to the inside or outside of the hole cup, it tries to correct the putting posture while changing his or her shoulder or arm motion.

However, it is much more effective for a golfer who is familiar with his putting motion to have his or her own putter suitable for his putting motion rather than correcting his or her putting posture. Changing the familiar putting behavior is not only time-consuming, but also often loses its own sense of putting during the calibration process. In other words, each golfer has his or her own physical condition or unique habit. For example, a golfer with a tall or long arm bends his / her arms consciously, so he puts a golf ball on the top of the golf ball for a longer time than the target, while a golfer with a strong grip on the right hand IN) line. Accordingly, the golfer who has learned the characteristics of the putting operation suitable for him uses the putter to replace or fit the putter to match his putting motion rather than correcting it. The fitting process of the putter takes place in a place that specializes in the sale and repair of golf clubs. First, after the golfer removes the golf grip, the length of the shaft is shortened according to the golfer's order, or the left and right angles of the head surface are precisely adjusted, and then the new grip is fixed again.

This fitting process was not only time-consuming and costly, but also was troublesome because it was necessary to re-fit the putter after completing the fitting once and time and cost again. For this reason, weekend golfers tried to change their putting behavior more and more, rather than fitting their own putter, which was a major cause of not increasing putting ability.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and it is an object of the present invention to provide an apparatus and a method for adjusting a face of a head to be opened or closed so that a user can perform a pushing and pulling The golf ball can be corrected in its angle by the error, thereby providing a putter that increases the probability that the hit golf ball has a correct direction and goes straight to the target hole cup and can hold it.
