Description

A putter for golf club

The present invention relates to a putter, which is one of golf clubs, and more particularly, to give an address stability when putting, and to adjust the shaft length, the angle between the putter head and the shaft (lie angle) and the weight of the putter head according to physical conditions. It is possible to optimize the keen putting feeling according to the characteristics and conditions of each player, and relates to a golf club putter that can comfortably target the AIM.

In general, golf is an exercise that puts golf balls into hole cups on the green with the lowest possible number of hits using various golf clubs.

Putting practice is a good practice when practicing with a putter that takes into account the individual's body shape and personal movement characteristics, but if it does not, effective practice is not achieved by taking an improper putting posture. You can't expect it. In the game of golf, the number of putters accounts for half of the regular strokes, so anyone realizes the importance, but it is difficult to practice putting and selecting a putter that suits your personal characteristics is more difficult. It leads to trial and error and costly loss.

In particular, the golf putter 100 has a shaft 110 formed of a metal or carbon fiber material, as shown in Figure 1, the grip (handle) 120 formed on the top of the shaft, and to hit the golf ball directly It consists of a head 130 made of a metal material, which is connected to the shaft through a neck (neck).

Selection of putters having the above-described configuration puts a lot of pressure on beginner golfers. The selection criteria for putters are shaft 110 length, putter face angle, lie angle (a), weight, and overall balance of putters. Works organically (see Figure 1, which shows a general putter 100).

And even though we currently select putters that meet all of these points, the need for another putter is created by the individual change that comes from the difference between the amount of practice and the practice method.

That is, the length of the shaft, lie angle, putter face angle, weight and swing balance are very important for the golfer's personal characteristics, and the swing balance is a combination of the weight of the head and the weight of the grip part. It is very sensitive enough to be influenced by it. Currently, among the standard product putters that are constantly fitted (fitting) by each manufacturer, the golfer chooses to purchase one close to his / her own body type according to the personal characteristics of the golfer.

However, it is difficult to choose a putter that fits each person's body type before actually using it, and there is a limit to coping with a personally changing balance sense because the balance sensation changes according to the shape change, skill acquisition, and golfer's physical condition. .

In the past, there is a case where a putter has been developed that can change the lie angle, but when the lie angle of the putter changes, the center of gravity of the putter head comes, but there is a solution that can cope with the change of the center of gravity, thus limiting the effectiveness in There is no real purchase.
