Description

{HANDFORWARD GOLF CLUB FOR AMATEUR}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a golf club used to hit a golf ball, and more particularly, to a golf club including a head having a face as a striking face striking a golf ball and a shaft as a rod portion.

Generally, a golf club is a golf club which is generally called a golf club, and includes a head having a face as a striking face for hitting a golf ball and a shaft made of steel or graphite as a rod portion of the golf club And are classified into wood, iron, and putter according to the shape and material of the head, and they have different uses and functions.

Wood clubs are clubs that send golf balls as far away as possible, iron clubs are clubs that are chosen according to the right distance, and putters are clubs used to determine the score by putting the golf ball on the green in a hole cup. There is also a practical utility club, a hybrid type of wood club and iron club.

These woods and irons are numbered for each golf club, and the longer the club goes, the longer the wood is.

Referring to FIG. 1A, when a beginner starts to learn golf for the first time, the pair of feet are spread at regular intervals, and then the golfer's arm and golf club are prepared to form an English capital letter "Y" The sole, which is the bottom of the head, can be easily positioned in parallel with the ground.

However, when the golf club reaches the impact point hitting the golf ball placed on the ground through the downswing after the backswing, the golfer's arm and golf club are formed in the shape of the English lower case "y " You must maintain a hand-held posture that is positioned in front of the head.

Such a hand-forward type posture is very important in impact, and therefore, the distance and direction of the golf ball are greatly influenced. However, a general amateur golfer who has not been systematically trained correctly maintains such a hand- It is not easy to impact a golf ball. Rather, as shown in FIG. 1D, a golf ball is frequently pushed up and often causes a wrong distance or direction of the golf ball.

In addition, as shown in FIG. 1A, it is not easy for a general amateur golfer to maintain the shape of the English capital letter "Y" in the prepared posture and then switch to the form of the English lowercase letter "y" at the impact of the golf ball through the backswing and the downswing.

When swinging in a hand-forwarded posture with the form of an English capital letter "Y" from the initial preparation position, the likelihood of a golf club becoming a bad shot due to a severe tilt increases, Distance and direction are not constant, and the harmony may be broken by the distance difference between the golf clubs.

Also, as shown in FIG. 1E, since a professional golfer has sufficient strength and flexibility and has been systematically trained even if he or she puts a golf ball in the middle of a pair of legs, the head of the golf club during the swing, like the solid- , The golf club head swings in a swing direction after passing through the position of the golf ball. However, when the amateur golfer puts the golf ball in the center of the swing, So that the exact impact interval narrows and the probability of a wrong shot increases.

Thus, as shown in FIG. 1F, an amateur golfer can swing the golfer with an ideal swing trajectory such as a professional golfer by placing the golf ball slightly to the right foot than the middle position of the legs and then swinging, The head of the golf club is severely tilted as shown in FIG. 1G, so that the original design of the golf club can not be utilized and the golf ball can be sent to the desired distance. There is no problem.

The present invention has been devised in order to solve all of the above-mentioned problems, and it is an object of the present invention to provide an impact point striking a golf ball with a back swing and a down swing, The posture of the hand forward type can easily be maintained in the golf ball. Since the loft angle is not changed as intended in the design of the original golf club and the head of the head is not tilted so as to be parallel to the ground, So that the distance and direction of the golf ball can be kept constant, and the swing is easy and easy.

According to an aspect of the present invention, there is provided a golf club comprising a head having a face, which is a striking face against which a golf ball is struck, and a shaft as a rod portion, Wherein the shaft is inclined from a vertical line toward a side opposite to the face of the head by a predetermined shaft angle.

At this time, in a state in which the golfer is in a ready state in which the two legs are opened, a hand posture type posture is taken so that both arms and the shaft form a letter "y" in English, and the golf ball is positioned on the right side of the golfer, And the loft angle, which is the angle formed by the vertical line of the head and the face of the head in the vertical direction at the leading edge of the head, is kept constant.

In addition, the golf club is an iron club, and the shaft angle is also characterized by an angle in the range of 3 to 20 degrees.

In addition, the golf club is a utility club, and the shaft angle is also characterized by having an angle in the range of 3 to 15 degrees.

In addition, the golf club is a wood club, and the shaft angle is also characterized by an angle in the range of 3 ° to 10 °.

In addition, the golf club is an iron club, and has an opening angle of 7.5 ° or less, which is an angle formed by the normal line of the acetabular line and the swing locus.

Further, the golf club is a utility club, and the opening angle of the head, which is the angle formed by the normal line of the acetabular line and the swing locus, is 2 DEG or less.

In addition, the golf club is a wood club, and the opening angle of the head, which is an angle formed by the normal line of the acetabular line and the swing locus, is 2 ° or less.

According to the present invention, a hand posture type posture can be taken from a ready posture, and a back forward swing and a down swing are performed with a golf ball slightly on the right foot side, so that a hand forward type posture can be easily maintained at an impact point striking a golf ball , The loft angle does not change as intended in the design of the original golf club, and since the sole of the head is not tilted, it becomes parallel to the ground, so that the swing's usability is increased and the flying distance and direction of the golf ball are kept constant And the swing is easy and easy.

Hereinafter, the contents of the present invention will be described in detail with reference to the accompanying drawings.

2, the hand forward golf club 1 for an amateur according to the present invention includes a head 20 having a face 25 as a striking face striking a golf ball B, 10) and a grip grip (30) formed on the upper portion of the shaft.

At this time, the shaft 10 may be made of various materials such as steel, titanium, graphite or composite materials thereof, and a grip 30 having a non-slip surface for gripping the golf club 1 may be formed do.

2, the head 20 includes a top 21 corresponding to the top surface, a sole 22 corresponding to the bottom surface, a toe 23 corresponding to the front end, A face 25 which is provided between the tow 23 and the heel 24 to form a striking face striking the golf ball and a face 25 which is provided between the toe 23 and the heel 24, And a leading edge 26, which is a sharp portion.

3, the hand-for-golf club 1 for an amateur according to the present invention is characterized in that the sole 22, which is the bottom of the head 20, is parallel to the ground, Is inclined toward the other side opposite to the face 25 formed by being slightly inclined to one side by a predetermined shaft angle S about a vertical line.

However, when the golf ball is hit, the golfer's arm and the golf club are formed in the shape of a lower case letter "y" in English, so that the golfer's hand is positioned in front of the head. It is very important that the distance and direction of the golf ball is greatly influenced.

Thus, in the amateur golfer, after taking a stance with both legs spaced apart at regular intervals, the golfer's arms and golf clubs are ready to take the form of an English capital letter "Y" The golfer's arm and golf club should be converted into a hand-forwarded posture in which the golfer's hand is positioned in front of the head in the form of the English lower case letter "y" It is not easy for a general amateur golfer who has not received such a hand-forward posture to take an impact on the golf ball, and in addition to maintaining the form of the English capital letter "Y" in the ready position, It is difficult to switch to the English lowercase "y" form at the time of ball impact.

However, if the golfer takes a ready position in the form of a handwritten letter "y" in the form of a lower case letter from the beginning and swings the golf ball slightly biased toward the right foot, the address becomes relatively natural, And as a result, the sole of the golf club becomes much tilted, so that the leading edge 26 of the head 20 digs into the ground to increase the possibility of an erroneous shot.

However, in the case of using the hand-forward golf club for amateurs according to the present invention, even if the amateur golfer takes a hand-forward posture such that both the arms and the shaft 10 form a small letter "y" Golf clubs and sole are not tilted and you can use the correct shot.

4, when the golf ball B is positioned at a position offset to the right foot side of the golfer, the golfer performs a backswing and a downswing to move the golf ball B to the face 25 of the head 20, The sole 22 of the head 20 is parallel to the ground and perpendicular to the leading edge 26 of the head 20 and the face 25 of the head 20 The golf ball's flying distance and direction are maintained constant and the golf ball's flying distance and direction can be maintained constantly while using a single golf club. It is possible to solve the problem that the direction is not constant and the problem that the harmony is broken due to the difference in distance between the existing golf clubs.

In addition, as shown in FIG. 4, the backswing and downswing are performed with the golf ball slightly on the right foot side, so that the posture of the hand forward type can be easily maintained at the impact point striking the golf ball.

5 is a view showing the shaft angle S according to the preparation posture of the hand-for-hand golf club 1 for an amateur according to the present invention.

As shown in FIG. 5, when the preparation posture is taken, when the height to the golfer's shoulder is 140 cm and the shoulder length is 40 cm, the shaft angle ( S) varies depending on the position of the golf ball. When the golfer grasps the golf club in a straight line with the left arm, when the golf ball is placed in front of the right foot, the shaft angle s1 becomes 16 °, , The shaft angle s2 is 8.1 °, and when the golf ball is placed at a distance of two golf balls in the left foot direction from the center between the feet, the shaft angle s3 becomes 4.8 °. As a result of repetition through the golfers having various shoulder heights and shoulder lengths as described above, it was found that when the golfer had narrow shoulders or elongated golf clubs in the iron club, the shaft angle S was at least 3 °, The shaft angle (S) was found to be up to 20 ° for a tall, shoulder-width golfer.

In addition, when the golf club is a utility club, it has been found that the shaft angle S has an angle in the range of 3 ° to 15 °, and when the golf club is a wood club, the shaft angle S is in the range of 3 ° to 10 ° . &Lt; / RTI >

FIG. 6 is a view showing an opening angle (A) of an amateur hand forward golf club according to the present invention.

As shown in FIG. 6, when the golfer swings the golf club 1 by the backswing and the downswing around the center of the legs with the golf ball B positioned on the right foot side of the golfer, At the point where the club head 20 impacts the golf ball B, the swing trajectory becomes inside out, increasing the possibility of a draw or a hook.

In order to prevent such a phenomenon, the face 25 of the golf club head 20 must be opened to some extent and the opened angle A is equal to the angle formed by the normal line and the acetyl line at the point where the golf ball is placed do. Here, an acetabular line refers to a virtual straight line connecting a golf ball and a target point.

For example, according to the experiment, when the sum of the golfer's arm and the length of the golf club is 150 cm, when the golf ball is placed at a position (8.534 cm) apart from two golf balls from the center position of the feet to the right foot, The opening angle (A) between the normal line and the acetylene line was measured as 3.9 °. When the golf ball was placed in front of the right foot, the opening angle (A) between the normal line passing through this point and the acetabular line was measured at 15 °, Is positioned at the center of the pair of legs, the opening angle (A) becomes 0 DEG.

However, the above-described opening angle A corresponds to the case of swinging the golf club horizontally. Actually, since the golf club swings diagonally downwardly, the actual opening angle A is smaller than the above- . In this case, when the line connecting the shoulder to the head 20 of the golf club is 60 degrees with the ground, the opening angle A of the head 20 is the distance between the golf ball B and the golf club head (B) is 1.95 ° when the golf ball (B) is positioned at the center of the golf ball at a distance of two feet to the right foot, and 7.5 ° when the golf ball (B) is positioned at the right foot.

Therefore, when a golfer having a total length of arms and iron clubs of 150 cm is placed on a golf ball (B) at a distance from the center of the legs to the right foot by two golf balls and hitting the golf ball with the iron club, There is a high possibility that the golf ball is struck and straightly fed at an opening angle (A) of 0 to 7.5 degrees.

In addition, when the golf club is a utility club or a wood club, the opening angle (A) between the acetabular line and the normal line is measured within a range of 2 °.

As a result, the hand forward golf club 1 for an amateur according to the present invention can take a posture in the form of a hand-forward from the preparation posture, and is able to take the impact of hitting the golf ball with the backswing and down- It is possible to easily maintain the posture of the hand posture at the point, and as the intention of the original golf club does not change the loft angle as intended, the ball of the head is not tilted so as to be parallel with the ground, The distance and direction of the ball can be kept constant, and the swing becomes easier and easier.
