Abstract

PROBLEM TO BE SOLVED: To achieve the optimum grip size for golf clubs of respective uses from wood clubs to short iron clubs by varying the size of golf club shaft at the grip part sequentially in the order of the size number thereof per club or per group made in terms of the closeness of the number. SOLUTION: A grip (cover rubber) 2 is set at 250 mm in length, tapered from the extreme end to the tip thereof and a lower winding tap is applied inside the grip 2. Wood clubs provided with this grip part are grouped into a set of number 1, 3 and 4 and combined with iron clubs in a set of number 3 to 9 from pitching wedge to pitching sand and sand wedge types... in total of ten. Then, the diameter of the shaft 1 at the grip part is reduced according to the increase in the size number of the clubs in terms of the diameter A (the diameter of the extreme part of the shaft 1 at the grip part) and the diameter B (the diameter of the tip part of the shaft 1 at the grip part).

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a golf club set of usually 13 or less golf clubs excluding putters, a set of only wood clubs, and a set of only iron clubs.

[0002]

2. Description of the Related Art The thickness of a grip portion of a golf club is mainly obtained by adding the thickness of a grip cover rubber to the size of a shaft. Generally, the thickness or diameter of the grip is empirically determined to be the optimal grip thickness to accurately hit the ball with the face of the club head and to withstand the impact and swing the club in the correct direction. , The same thickness of the grip portion was applied to the clubs of each count other than the putter, so that the shaft thickness of the grip portion was also the same for each count.

However, in some cases, a thick grip is preferred in consideration of the directionality of the ball and the impact on the hand at the time of impact. In this case, a lower winding with a double-sided adhesive tape is thickly wound on a shaft of a specific count, and the entire grip is thickened by covering the lower winding with a grip cover rubber.

[0004] Recently, only the driver wood is used, and a shaft whose entire shaft is extremely thick has emerged, and attempts have been made to improve the directionality of hitting a long shaft in a fashionable fashion. The thickness of the grip part of the driver wood club alone is extremely thick.

[0005]

If the grip portion is too thick, it cannot be gripped by fingers alone, but must be firmly gripped by the entire palm of the hand, and the wrist is fixed. While the rotation is suppressed, it becomes easier to catch the ball accurately on the face surface of the club head, but the free movement of the fingers and wrists makes a subtle hitting, and the rotation of the wrist increases the head speed and makes a strong impact There are characteristics that make it difficult to do things.

[0006] Therefore, as in the above-mentioned conventional general clubs, all clubs are available, from wood clubs and long irons, in which a particularly large flight distance is emphasized, to short irons, in which directionality and accurate flight distance are particularly important. When the grip thickness is the same, the grip characteristics described above are not sufficiently utilized, and the improvement in club performance is suppressed.

In the case where the lower winding tape is wrapped around the shaft and the grip portion is made thicker, a process of making the grip thicker is added to a product which has been completed in advance. Therefore, there is a problem that a so-called swing balance of the adjusted shaft is broken, and that the processing is complicated.

Further, in the case of the extremely thick shaft, only the grip portion of the long driver club becomes extremely thick, and taking advantage of the above-mentioned shaft characteristics, each club of each count constituting the set is used. It does not set the grip thickness suitable for the role.

Accordingly, an object of the present invention is to provide a golf club set in which clubs for various uses from wood clubs to short irons have optimum grip thicknesses.

[0010]

SUMMARY OF THE INVENTION To achieve the above object, the present invention provides a golf club set comprising a plurality of golf clubs excluding a putter, wherein the thickness of the golf club shaft of the grip portion is in the order of the number. , For each individual club, or for each group of clubs with similar numbers.

[0011]

Preferred embodiments of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is a cross-sectional view showing a grip portion of a shaft 1 of a golf club. The length of the grip (cover rubber) 2 is 250 mm, and a taper that becomes thinner from the end to the tip is provided. A lower winding tape 3 is wound around the inside of the grip 2. A wood club having such a grip portion is set as No. 1, No. 3, and No. 4, and as an iron club, No. 3 to No. 9, pitching wedge (P), pitching sand (PS), and sand wedge (S). When 10 sets are combined, the diameter of A at the grip portion of the shaft 1 (the shaft 1 at the grip portion)
And the diameter of B (the diameter of the distal end of the shaft 1 in the grip portion) were set as shown in Table 1 below.

[0013]

[Table 1]

In the golf club set shown in Table 1, as the club number increases, the shaft 1 at the grip portion increases.
The diameter of has been reduced. Therefore, in the case of a wood club or a long iron, the movement of the wrist at the time of the swing becomes small, and the swing becomes stable, and it becomes easy to hit the face surface squarely with the ball. Also, in short irons, it is easy to hit the ball on the face from the specifications (loft angle, sole width, shaft length, etc.), so you can freely move the wrist, such as controlling the amount of spin according to the approach situation The diameter of the shaft at the grip has been reduced so that various subtle punches are possible.

Contrary to the embodiment shown in Table 1, the thickness of the shaft 1 in the grip portion can be made to flow. In such an embodiment, in a wood club or a long iron, a force is easily applied during a swing due to a thin grip, and the speed of the club head is increased, so that the flight distance of the ball can be increased. On the other hand, the short iron has a thick grip, so that a stable stroke without using the wrist can be made, and an accurate shot with few mistakes such as a duff and a top can be performed.

In still another embodiment, a wood club,
Between the long iron and the middle iron, the diameter of the shaft of the grip is made to flow gradually thinner in the order of increasing iron count, and three wedges (P, PS, S) are set as a golf club set with a larger shaft diameter. You can do it. In this case, in addition to the features of the club set of the embodiment shown in Table 1, the wedge club does not use the wrist, that is, accurately hits the ball on the face surface with a stable stroke that does not rotate or return the wrist. It becomes possible to hit.

Further, as a method of the flow of the diameter of the shaft 1 of the grip portion, any of the three types shown in Table 2 below may be used.

[0018]

[Table 2]

In the methods I to III shown in Table 2,
A grip portion having no taper from the diameter A to the diameter B may occur. Further, the above method is defined as I or II, the variation of the outer diameter within the set of the shaft 1 at the tip of the grip is 3 mm or more, and the variation of the thickness of the shaft 1 at the tip of the grip is It is preferable to set so as not to become smaller than the variation of the thickness. By setting such an amount of variation, a thin taper at the tip of the grip can be easily adopted, and a good grip feeling can be obtained.

In the above-described embodiment, a set in which a set of wood clubs and a set of iron clubs are combined has been described. However, it is a matter of course that the present invention can be applied to a set of only wood clubs or a set of only iron clubs. .

In the above embodiment, the diameter (B) of the tip of the grip is set to be smaller than the diameter (A) of the end of the grip, and the tip of the grip has a small taper. Is the value at the tip of the grip,
Also, by setting the value of B as the value at the end of the grip,
The diameter (B) of the grip tip is the diameter (A) of the grip end
By setting a larger value, the end of the grip can have a narrow reverse taper.

[0022]

As described above, according to the present invention, the thickness of the grip portion is changed to the turn sequence of the club by changing the thickness of the shaft of the grip portion. When the thickness is increased, excessive rotation of the wrist during the swing is suppressed, the face of the club head easily hits the square with the ball, and the directional stability of the ball increases. In addition, when a long iron, which a general golfer is not good at, also has a thick grip, it is easy to hit the face core and the directionality is improved. In the short iron, when the grip is set to be thin, the wrist is easy to use, various subtle hits such as spin control can be performed, and a variety of shots according to changes in the situation around the green can be made. Conversely, if the grip thickness from the wood club to the long iron club is reduced and the grip thickness of the short iron club is set to be large, the wood club or long iron club must have a small grip when swinging. Is easy to enter, the head speed increases, and the flight distance of the ball increases. The short iron allows a stable stroke without using the wrist due to the thick grip, and enables accurate shots with less mistakes such as duffling and top. further,
The change of the grip thickness, that is, the flow, is performed by changing the thickness of the shaft of the grip portion, and the swing balance of the shaft is set in consideration of the variation of the shaft thickness in advance. This prevents the swing balance from being improperly broken.
