Description

Putter head with straightness improvement structure

The present invention relates to a golf putter head, and more particularly, to a golf putter head which is capable of minimizing swing of a putter head during a putting process, thereby maintaining stability of a putting stroke, To a putter head constituting an improved structure.

In general, golf is a game in which a golf ball that is stationary on the course is hit by the head of the golf club and put in a predetermined hole, and the ball is driven by the number of strokes until that time.

A golf club used in such a golf is composed of a head having a hitting face for hitting an actual golf ball and having a hosel on one side and a shaft having a lower end coupled to the hosel and a grip on the upper end, Depending on the purpose of the head, it is divided into Wooden Club, Iron Club and Putter.

Wood clubs, which are divided into drivers and fairway woods, are used for long-distance shots. Iron clubs, which are divided into long, medium and short irons, are used for medium-range shots. Or selected from among the various types described above depending on the angle to be hit.

In addition, the putter is mainly used for putting in a hole cup which is located at a relatively short distance and weakly hit or rolled rather than hardly hit the golf ball on the green of the field. It is generally used in a form of T shape, egg shape, Type, and the type classification is classified into a face balance type, a toe balance type, and a heel to balance type.

Particularly, a putter is a golf club which is used for putting a golf ball put in green into a hole. The putter is a golf club which adjusts the strength of putting (putting speed) Accurate straightness is required, which can be transmitted in the desired direction.

These golf putters have a tendency to reduce the travel distance of the golf ball if the impact of the putting is not made at the center of the hit point and the direction of movement of the golf ball is not as desired and the putting of the impact from the center of the hit center, I can not.

The putter head of the existing putter head and the shape of the head are various in consideration of the appearance center, the weight, the shock absorbing function, and the putting feeling at the time of hitting, but when the putter does not hit the center of the hit accurately It is difficult to hit the golfer in the intended direction due to the opening or closing of the striking surface of the club due to the slight distortion of the face. This means that golfers are minimizing this by a lot of repetition exercises, but they can miss the chance of winning or the game is overturned due to a putting mistake due to the pressure and tension at the crucial moments that determine the game.

In addition, the height of the striking face of the conventional putter head is about 20 to 30 mm. The actual contact surface between the ball and the putter striking face is a circular shape having a diameter of about 5 to 6 mm, which is 1/4 to 1/6 It is difficult to hit by the center of gravity in the putting stroke, so it requires many repetition drills.

Then, the impact is applied to the putter at the moment when the putter face collides with the ball, and the impact causes the impact surface of the putter to be slightly twisted so that the force applied to the ball from the putter can not be accurately applied to the ball.

However, in the case of a general putter, the center of gravity thereof is located at the lower end and the rear end. Thus, the swing of the putter head during the stroke process is considerable, and this swing does not correct the ball striking, .

In addition, the shaking of the normal putter in the stroke process is accompanied by an unnecessary force, and it is not easy to adjust the distance.

On the other hand, a center-of-gravity moving device capable of being mounted on a shaft of a golf putter for adjusting the center of gravity in the near future has been proposed.

However, since the center-of-gravity shifting device as described above controls the weight of the shaft rather than the action of the putter head, it is impossible to finely control the shaft. In particular, due to the nature of being mounted on the shaft, .

The present invention was conceived to solve the above-mentioned problems, and the present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a putter head in which the center of gravity of the putter head is located at the front portion and the upper portion, The present invention has been made to solve the above-mentioned problems occurring in the prior art, and it is an object of the present invention to provide a putter head having a straightness improving structure for ensuring stable straightness even when striking a golf ball at a position deviated from the center.

Another object of the present invention is to provide a putter head having a straightness improving structure for enabling a precise stroke, such as enabling a stroke with a relatively small force through an upper and a forward center of gravity.

It is another object of the present invention to provide a putter head having a straightness improving structure for enabling correction of a putting posture through repeated practice in a state in which straightness is secured.

As a specific means for achieving the above object, the putter head has left and right lengths forming a heel on the golfer's body side and forming a tow on the outside, a face on the front face, and a gentle upward slope on both sides of the bottom face A head body having a hosel formed at an upper center of the head so as to be inclined toward the heel side and protruding upward to engage the shaft; And

And a weight wing portion protruding from a rear surface of the head body toward the rear side,

The weight wing portion,

A central wing portion protruding rearward from an upper center portion of the head body and striking a golf ball; And

And a side wing portion that protrudes more than the central wing portion from both sides of the head body rearwardly,

The central wing portion has a rectangular shape in cross section,

Each of the side wing portions has a shape of an inverted right triangle forming a downwardly inclined wing slope extending from the rear end to the rear end bottom face of the head body,

The upper surface of the head body and the upper surface of the central blade form a plurality of rows of scales on both sides of the center and a gap corresponding to the diameter of the golf ball in a direction perpendicular to the head body,

The weight ratio between the front head body and the rear weight wing is 7: 3,

The weight ratio of the upper part to the lower part is 7: 3,

And the weight ratio of the center wing portion side to the side wing portion sides on both sides in the left and right direction is 3: 4: 3.

As described above, the putter head constituting the improved straightness improving structure according to the present invention has a 7: 3 ratio of the center of gravity of the putter head to the front and the rear, a ratio of 7: 3 between the upper and lower portions, 3: 4: 3 ratio. In the stroke process, it is possible to make a stable stroke without shaking through the forward and the upper center, thereby ensuring the straightness of the head and precisely striking the golf ball. In particular, Even if hit, the weight is given, and the straightness is ensured without shaking. Therefore, it is possible to obtain an effect that is always stable and can be accurately putted.

In addition, stroke can be made with a comparatively small force through the center of gravity of the upper part and the front part at the time of stroke, and it is possible to obtain an effect of enabling precise putting with a small force.

In addition, it is possible to calibrate the posture in which the immediacy can be secured naturally in repetitive practice, and it is possible to achieve stable putting even when another putter head according to the correction of the putting posture is used.
