Description

Golf clubs with reference system for improved accuracy for address}

The present invention relates to a golf club having a reference system for improving accuracy for improved address, and more specifically, the angle of the lie angle and the socket coincide at the starting point when addressing using irons used in Tees or Fairways. It relates to a golf club having a reference system for improved accuracy for addressing with improved performance against typo of a golf ball by providing the most ideal and accurate angle (start).

As is well known, even if the golfer adjusts the swing of the golf club when hitting, the golf head acts as a free mass moving at a certain speed. Most of the energy of this moving mass is transferred to the golf ball in a moment, and the compressed golf ball against the front of the club will bounce vigorously, returning to its original spherical shape.

The most important factor related to the ideal hitting of the golf ball is that the hitting point of the hitting surface of the golf club head should be placed under the center of the head. The more downward the center is, the higher the hitting angle is and the more complete the batting angle is.

Since recent decades, many golf club manufactures have made golf club heads, called so-called “heavy club heads,” so that golfers can easily achieve the above objectives.

As most of the golf club's mass is concentrated on its bottom, the center of the head becomes lower, which makes it easier for the golfer to bring the center of the golf club head further down than the center of the golf ball.

Another important factor related to the ideal hitting of the golf ball is, first, the hitting point of the ball surface of the club head should ideally be aligned with the center of the club head and the center of the golf ball.

Second, the batting surface of the club head should be perpendicular to each other, that is, to the movement path of the planned surface of the golf ball. Both the center of the golf club head and the center of the ball and the center of the golf ball can be more precisely aligned when placed on a single vertical plane. Therefore, it is considered that the golf club head is precisely aligned and perpendicular to the theoretical plane including these three points when it is aligned with the planar movement path of the golf ball.

Third, since the body shape and constitution of each golfer are different at the time of addressing, the most ideal starting point (reference point) can be suggested by matching the angle of the lie angle and the socket, which are the correct starting points.

Deviation from the ideal alignment state will decrease the maximum energy transfer effect when hitting, and departure from the right angle will cause the golf ball to deviate from the planned normal course.

The following examples are intended to provide a complete understanding of the alignment and orthogonality problems mentioned above. Consider first the case where the golf club head is correctly aligned but does not form a right angle to the planned flight path of the golf ball. In this case, the maximum energy will be transmitted to the golf ball, but the moving path of the golf ball will deviate from the planned path. As a second case, consider the case where the club head is at a right angle at the time of batting, but the hitting point is out of the lateral direction toward the front or rear part of the club head, so that the correct alignment is not made. In this case, the amount of energy transferred does not reach the maximum amount, so a perfect hitting ball is not achieved and the golf ball cannot fly away. And the club head is rotated or twisted so that the right angle position will be changed by this rotation.

The term rotation or twist defines the rotation of the club head when hitting an axis that passes through the center of the club head and is parallel to the axis of the golf club shaft.

Even a highly skilled and experienced golfer will understand that it will be very difficult to achieve a highly perfect alignment and right angle. Therefore, most golf clubs are composed of iron golf club heads with relatively large mass concentrations at the back and front of the club head, which increase the moment of inertia, thereby maximizing energy transfer and suppressing rotation due to misalignment of the golf ball. Can be prevented.

The golf club iron head of the prior art is designed in the above-mentioned general method so that optimum anti-rotation characteristics are achieved and this purpose can be successfully achieved in various club heads. One basic technique used in various methods in various conventional iron golf club heads is to redistribute the mass by forming a central indentation on the back of the head or by forming indentations at predetermined positions and locations on the clubhead.

Another technique used is to form a relatively small indentation on the back of the clubhead to redistribute the indentation mass and to concentrate the load at predetermined positions on the front and rear of the clubhead.

In accordance with other design parameters, the anti-rotation characteristics of the iron golf club head depend on the mass and the specific mass concentration ratio and location, which are redistributed or concentrated on the rear and front portions of the club head. As mentioned above, the prior art has been tried many times to achieve optimum anti-rotation characteristics.

Therefore, it is desirable to provide a new golf club set having an iron head configured to provide improved anti-rotation properties compared to the prior art.
