Description

Multifunctional golf putter {A MULTI FUNCTIONAL GOLF PUTTER}

The present invention relates to a putter, which is one of the golf clubs, and more particularly, it is possible to adjust the shaft length, the lie angle between the putter head and the shaft and the weight of the putter head according to the physical condition, and putting feelings according to the characteristics and conditions of each player. The present invention relates to a multifunctional golf putter that can be optimized, provides an address stability when putting, and makes aiming at a target point comfortable.

In general, golf is a sport in which a golf ball is put into a hole cup on the green with the lowest possible number of hits using various golf clubs. The importance of putter in this golf movement is incredibly important.

In the game of golf, the average of putter accounts for half of the number of strokes, so everyone realizes its importance. Putting the ball into the hole cup requires a lot of putting practice to match the direction and distance to the hole cup because the ball's distance and direction are determined by the ball's strength and strength. However, the practice itself is difficult because the putting itself involves a very sensitive reaction.

Therefore, it is necessary to practice with a putter in consideration of the individual's body shape and personal movement characteristics, so that the effect of the exercise can be exerted and the improvement of skill can be brought. If you do not, you will not be able to expect to improve your skills because of improper putting posture.

In this way, putting practice is difficult and it is more difficult to select a putter according to personal characteristics. As a result, many golfers go through several trials and errors in the purchase of putters, resulting in a high cost loss.

Conventional golf putter 100 is a shaft 110 formed of a metal or carbon fiber material, as shown in Figure 1, the grip (handle) 120 is installed 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 the putter having the above configuration is putting a lot of pressure on beginner golfers. Conventional putter selection criteria are based on whether the shaft 110 length, putter face angle, lie angle (a), weight, and overall balance of the putter are organic.

Even if each player selects a putter that satisfies all of the above points, a change in the amount of practice and the method of practice will lead to the need for another putter purchase over time.

In other words, the length, lie angle, putter face angle, weight and swing balance are very important for the golfer's personal characteristics. The swing balance of the putter is determined by the balance between the head weight and the grip weight along with the weight of the head. Commercial putters are made up of standard products that are constantly fitted. Golfers are choosing to purchase one of these standard products closest to their body type according to their personal characteristics.

However, it is difficult to choose a putter that suits each person's body type before actually using it. In addition, there is a limit in dealing with the balance sensation that changes from time to time personally because the balance sensation changes according to the change in body shape, skill acquisition and body condition of the golfer.

Conventionally, there is a case in which a putter capable of changing a lie angle has been developed, but when the lie angle of the putter changes, a change in the center of gravity of the putter head comes. However, the above putter lacks a solution that can cope with such a change in the center of gravity, and has a limit in effectiveness, and thus no actual purchase is made.

The general putter head is made of a metallic material, it is difficult to match the distance because of the high resilience of the steel (steel) material. In the embodiment of the present invention, as shown in FIG. 3, a chamfering surface 5 is formed on the face 2a of the head 2 and the surfaces of the hemispheres 4 as shown in FIG. 3. One structure is presented.

In the present embodiment, the chamfering surface 5 has a structure in which a plurality of cubes or regular hexagonal pyramids (preferably 100 or more) are engraved within 1 cm 2. According to the structure of the chamfering surface 5, it is possible to soften the feeling of hitting at the time of impact of the ball and to freely give spin to the ball. Therefore, the directionality and distance control are excellent when putting. In addition, it is possible to maintain a soft hitting feeling by the player by the kneading processing of the face surface 2a, and accordingly, there is an effect of maintaining a sense of distance by feeling a distance that matches the rhythm of the player.

Preferably, the diameter of the golf ball is 42.67mm, so it is 36m ± 6 which is smaller than this. This is because when the height of the head 2 and the hemisphere 4 is out of the range of 36 mm ± 6, the size of the ball and the continuity of the line during alignment are visually different.

If the height of the head 2 and the hemisphere 4 is formed smaller than the golf ball as described above, an optical illusion or bending phenomenon in which the golf ball becomes larger at the time of the putting address occurs. This can impart continuity of putting and also has the advantage of making it easier to align the scale 4a to the center of the ball.

In addition, the present embodiment proposes a structure in which the length of the scale 4a is equal to or longer than the line marked on the golf ball. This has the advantage that the alignment of the golf ball and the putter head is easy, because the head can be moved in a straight line in the pendulum motion direction when putting, the direction is accurate. It can also prevent the head face from opening or closing. As a result, the address stability at the time of putting can be provided.
