DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a golf club set, and more particularly, to a golf club set having improved controllability of a hit ball in a high-count golf club.

[0002]

2. Description of the Related Art In general, a golf club set composed of iron clubs is composed of 1 to 3 long irons, 4 to 6 middle irons, and 7 to 9 irons and a short iron of sand wedge. With long irons, the overall length of the club is formed longer than that of middle irons and short irons so that the flight distance can be secured, and as the iron count rises to middle irons and short irons, emphasis is placed on controllability. The structure is such that the loft angle of the head is increased and the overall length of the club is shortened so as to enable sharp and sharp shots.

[0003] Then, as the count increases from long irons to middle irons and short irons, the head is sequentially increased by the amount corresponding to the shortening of the overall length of the club, so that all golf clubs can swing in a uniform form (feeling). The swing balance is set substantially constant. FIG. 2 shows the change of the balance point in the conventional golf club set 1, and the balance point BP is
As the count increases, it moves to the head 3 side. The balance point refers to a position on the shaft 9 where the head 3 and the grip 7 are balanced when one golf club 5 is placed on a plate having a thickness of, for example, about 5 mm.

As conventionally known, the swing balance is obtained by subtracting 14 inches from the length A between the balance point BP and the grip end 7a shown in FIG. 3, and adding this to the weight (ounce) of the golf club 5 as a whole. By designing the golf clubs 5 of each count so that the numerical values of the obtained swing balance are substantially the same,
All the golf clubs 5 can swing in a uniform form.

[0005]

As described above, conventionally, in the golf club set 1, the swing balance is set to be substantially constant so that all the golf clubs 5 can swing in a uniform form. As shown in FIG. 7, the grips 7 of each count are formed with the same dimensions, but the golf clubs 5 of high count such as middle irons and short irons are formed.
In order to easily control the hit ball by easily returning the head 3, the swing balance may be ignored and the golf club 5 may be gripped on the front side (head side) of the normal grip position (grip position). is there.

[0006] However, as described above, conventionally, in this type of golf club set 1, each of the grips 7
Are formed in the same dimensions, so that the grip area is restricted. As a result, when the golf club 5 is swung while gripping the golf club 5 in front of the normal grip position, in the worst case, the golf player swings while gripping the shaft 9 portion. There was a problem that had to be done.

[0007] The shaft 9 itself is thinner than the grip 7 and may be slippery, so that the directionality of the hit ball is often disturbed despite the emphasis on controlling the hit ball. It was a fact. The present invention has been devised in view of such circumstances, and an object of the present invention is to provide a golf club set that solves the above-mentioned disadvantages and improves the controllability of hitting in a high-count golf club.

[0008]

In order to achieve the above object, the golf club set according to the first aspect is characterized in that the grip attached to the shaft is sequentially lengthened as the count increases. According to a second aspect of the present invention, in the golf club set of the first aspect, the swing balance of the golf clubs of each count is made substantially constant.

(Function) In the case where the invention according to each claim is applied to, for example, an iron club set, if the ball is hit with the grip held in a normal position, the flying distance of the long iron is the same as in the conventional case. As the number increases to middle iron and short iron, a shot with sharp spin and sharpness becomes possible.

For example, when a player hits a ball with a short iron, the head is easily formed so that the head can be easily returned to control the hitting ball more accurately. It is sufficient to grasp the distal end side of the grip, and the grip prevents the hand from slipping, and the grip end side becomes heavier and the head returns faster by the amount of gripping the distal end side.

According to the golf club set of the second aspect, since the swing balance is set to be substantially constant over all counts, the player can swing in a uniform form.

[0012]

Embodiments of the present invention will be described below in detail with reference to the drawings.

FIG. 1 shows an overall view of an embodiment in which the invention according to claims 1 and 2 is applied to an iron club set. As shown in FIG. 1, a golf club set 11 according to this embodiment is also a conventional golf club set. Like the iron club set, it consists of 1 to 3 long irons, 4 to 6 middle irons, and 7 to 9 short irons, from 1 iron 13 to 9 iron 15 As the club number increases, the overall length of the club is shortened, and the loft angle of the head 17 is sequentially increased from the first iron 13 to the ninth iron 15.

As the club length is shortened as the iron count increases from the first iron 13 to the ninth iron 15, the head 17 is sequentially heavier as the iron count increases to the middle iron and the short iron. By moving the balance point BP toward the head 17 as the count increases, the swing balance is set to be substantially constant so that the swing can be performed in a uniform form over all counts.

Thus, the golf club set 11 according to the present embodiment has the same configuration as the conventional one as described above, as well as FIG.
As shown in (1), the length of the grip 21 attached to the base end side of the shaft 19 is gradually increased as the iron count increases from the first iron 13 to the ninth iron 15. Incidentally, in order to manufacture the grip 21, the grip 21 having a different length may be manufactured by creating a different mold for each count, or the grip 21 of the longest ninth iron 15 may be manufactured.
May be manufactured by cutting the head-side end portion of each head.

Conventionally, the general length of a grip mounted on a golf club is 250 mm to 280 mm. However, in the golf club set 11 according to this embodiment, [Example 1] $ 1200 mm, $ 5 300 mm , ♯9 400m [Example 2] ♯1 250mm, ♯5 280mm, ♯9 300m [Example 3] ♯1 250mm, ♯5 260mm, ♯9 280m, etc. If it is longer, the range can be selected as appropriate,
For example, in Example 1 above, # 3 or # 4 may be set to a standard length (250 mm to 280 mm).

Since the present embodiment is configured as described above, if the ball is hit with the grip 21 held in a normal position, the flight distance is ensured with a long iron as in the conventional case, and the middle iron and short The higher the iron count, the sharper the shot becomes. Then, since the swing balance is set to be substantially constant over all counts, the player can swing in a uniform form.

For example, when the player hits the ball using the ninth iron 15, the player can easily return the head 17 to accurately control the hitting ball. When you want to swing, use the long grip 21
The grip 21 prevents the hand from slipping, and the grip end 21a becomes heavier by the amount of gripping the distal end side.
Will return earlier.

Therefore, according to the present embodiment, by gripping the normal grip position, it can be used as a general golf club set. The controllability of the hit ball in the golf club is improved. In the above embodiment, the present invention is applied to an iron golf club set. However, the present invention can be applied to a wood golf club set.

[0020]

As described above, according to the present invention, by gripping the normal grip position, it can be used as a general golf club set, and of course, the grip position can be changed. Thus, the controllability of the hit ball in a golf club having a high count is improved as compared with the related art. According to the golf club set of the second aspect, since the swing balance is set to be substantially constant over all counts, there is an advantage that the player can swing in a uniform form.
