Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a grip for a golf club, particularly a grip suitable for a pantograph type horizontal push golf club proposed by the present inventor.

The principle of the pantograph type horizontal push golf club invented by the present invention is as shown in Fig. 1. The grip (6) is held from both sides with both hands (4) and (5) from both shoulders (2) and (3) of the head (1). Grip the four joints of both shoulders and wrists (7) (8) (9) (
10) connecting the four sides (2, 3) (11) (12) (4, 5
) to form a pantograph, and the joints of both shoulders (7) (
Swing your arms (11) and (12) around point 8) and move the golf club in parallel (13), (14), and (15).
The ball (1) always keeps the club face (16) square.
7) This is a club that hits the ball straight. This is like the conventional club shown in Figure 2, where you hold the grip (20) with your left and right hands (18) and (19) overlapping each other as if you were squeezing a towel.
There is no need to hold the grip, and therefore the body is not forced to exercise, and for this reason, the grip (6
) is completely different from the grip (20) of the conventionally known golf club, and the present invention determined the ratio of the width or depth of the grip to the length after repeated experiments.

The conventional grip was as shown in FIG. 2, and the width of the grip was tapered, and the ratio of the grip width to length was as shown in Table 1.

In addition, the width or depth of the grip described in this specification is the average value of the grip part of the golf club, with the thickest part being D1 and the thinnest part being D2. The length is the length of the gripping part, which is indicated by L, and the ratio is the ratio of the average width or depth of the gripping part to the length L of the gripping part.

Regarding D1, D2, and L, Figure 3 shows Wood No. 3 in Table 1.
Figure 4 shows an example of the grip of the present invention, D1=D2=43mm.
L=151 mm, and both FIGS. 3 and 4 are 1/3 scale of the actual product.

Table 1 To explain the embodiments of the present invention using drawings, as shown in Fig. 5, the diameter, width or depth of the grip (22) attached to the shaft (21) of the golf club (13) is D, and the length is L. Then, the grip has the following relationship.

0.09≦D/L≦1.0 The reason for this ratio is that, as shown in Figure 5, the left and right thumbs (23) and (24) are placed on the grip in parallel, and the grip is The basic ratio is the ratio of the minimum width of the top surface for gripping from both sides to the length of the palm, and this allows the player to hit the ball with a pantograph-style swing.

If the ratio D/L of the present invention is smaller than 0.09, the grip will be long and heavy, and the head will have to be made heavier for balance reasons, making the entire grip heavier. Also, if the grip part is heavy, it will be top heavy and the swing will become unstable and difficult to swing.

According to the invention, for example, a head of 337 grams, a grip of 1
The weight is 30 grams, the weight of the head WH and the weight of the grip W
The ratio of G is WH/WG=2.59, but the ratio is 0.0
If it is less than 9, this value will be extremely small and it will be difficult to hit. If the ratio D/L is greater than 1.0, the length of the grip will be too small, the palm will protrude and it will be difficult to grasp the ball reliably, the direction of the ball will not be stable, or the grip width or depth will be too large.

Through repeated experiments, the present invention has developed a grip that is shorter in length and wider than conventional grips, and by adopting a ratio within the above-mentioned range, it not only becomes possible to perform side-to-side hitting, but also reduces the weight of the grip, resulting in a better head/grip ratio. is large and easy to hit,
Moreover, not only can the club as a whole be held light and yet securely, but it is also possible to obtain an ideal grip for a club that is pushed laterally in pantograph-type swinging.

The present invention allows the golf club to be accurately moved in the lateral direction as shown in FIG.
) (14) and (15), you can swing and hit the ball efficiently, improving your score, and you can also obtain a grip that has remarkable effects, such as contributing to health improvement without forcing your arm to exercise.

Although the present invention can be modified in various ways in addition to the above-mentioned embodiments,
All of these are included in the present invention. The present invention can be applied to various golf clubs such as putters, drivers, golf clubs, and irons.
