Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a golf club set, and more particularly to a golf club set having improved long iron club, middle iron club, and short iron club head shapes.

[Prior Art] Generally, a golf club set including an iron club is disclosed, for example, in Japanese Utility Model Publication No. 62-38676, in which a long iron club numbered 2 to 4 and a middle iron numbered 5 to 7 are used. It is composed of clubs and short iron clubs such as 8 to 10 and sand wedge.

Then, in the head of the golf club set disclosed in this publication, the thickness of the ball striking face of each head becomes thinner as going from the long iron club to the short iron club.

With such a golf club set, it is possible to exhibit the original function of each iron club, that is, the function of accurately dropping the ball to the target point and stopping the ball, without adding a special separate member. Becomes

[Problems to be Solved by the Invention] However, in such a conventional golf club set, since the thickness of the ball striking face changes, the shot feeling in each iron club is different, and the features of each iron club are the same. There was a problem that it was difficult to fully draw out.

The present invention has been made to solve the conventional problems, and an object of the present invention is to provide a golf club set capable of sufficiently bringing out the characteristics of each iron club with the same shot feeling.

[Means for Solving the Problems]

A golf club set according to the present invention is a golf club set consisting of a long iron club, a middle iron club, and a short iron club, wherein the intermediate wall thickness of the middle portion of the head of each iron lug is substantially the same, The upper wall thickness of the upper part of the middle portion of each head is increased as the length from the long iron club to the short iron club is increased.

[Action]

In the golf club set of the present invention, since the intermediate thickness of the intermediate portion of the head of each iron club is approximately the same, elastic deformation (vibration characteristics) of the impact surface of each iron club upon impact at impact is approximate. It will be what you did.

In addition, the upper part of the middle part of each head is thicker as it goes from the long iron club to the short iron club, so that the long iron club has a soft feeling and has a long flight distance. The club has a hard feeling that the ball line at the start of the ball is low, the ball rises near the falling point, and the ball stops well when falling.

〔Example〕

Hereinafter, the details of the present invention will be described with reference to the embodiments shown in the drawings.

FIG. 1 shows an embodiment of the golf club set of the present invention, in which only the heads of each count are shown.

That is, in the figure, reference symbol A is three heads 2a, 3a, 4a of three long iron clubs 2 to 4, and reference symbol B is
3 middle iron club heads 5 to 7
Reference symbol C indicates a, 6a, 7a, and a short iron club composed of three iron clubs 8a, 9a, 10a of Nos. 8 to 10 and one sand wedge (SW) 11a.

Then, in this embodiment, the head of each iron club is
The intermediate portions 2b, 3b ... 11b of the intermediate portions 2a, 3a ... 11a have substantially the same thickness T.

Further, the upper wall thicknesses W2, W3 ... W11 of the upper portions 2c, 3c ... 11c of the middle portions of the heads 2a, 3a ... 11a go from the long iron club A to the short iron club C. Therefore, it is thickened.

In this embodiment, W1 <W2 <W3 <W4 <W5 <W6 <W7 <
W8 <W9 <W10 <W11.

2 and 3 show details of the head 2a of the No. 2 long iron club. In FIG. 2, reference numeral 2d indicates a sole portion, reference numeral 2e indicates a hosel portion, and reference numeral 2f.
Shows a step portion that partitions the intermediate portion 2b and the upper portion 2c. Further, in FIG. 3, reference numeral 2g indicates a face portion, and reference numeral 2h indicates a back portion.

In the head 2a of this No. 2 iron club, the back part 2h
A concave portion 2j having a shape larger than that of the head 5a of the middle iron club is formed in.

FIGS. 4 and 5 show the details of the head 5a of the long iron club No. 5, in which the reference numeral 5d indicates the sole portion, the reference numeral 5e indicates the hosel portion, and the reference numeral 5f.
Shows a step portion that partitions the intermediate portion 5b and the upper portion 5c. Further, in FIG. 5, reference numeral 5g indicates a face portion and reference numeral 5h indicates a back portion.

In the 5th iron club head 5a, the back part 5h
A concave portion 5j having a shape larger than that of the head 8a of the short iron club is formed in.

6 and 7 show details of the head 8a of the No. 8 long iron club. In FIG. 6, reference numeral 8d indicates a sole portion, reference numeral 8e indicates a hosel portion, and reference numeral 8f.
Shows a step portion that partitions the intermediate portion 8b and the upper portion 8c. Further, in FIG. 7, reference numeral 8g indicates a face portion and reference numeral 8h indicates a back portion.

In the 8th iron club head 8a, the back part 8h
A concave portion 8j having a shape smaller than that of the head 5a of the middle iron club is formed in the.

In the golf club set configured as described above, the intermediate portions 2b, 3b of the heads 2a, 3a ...
..The thickness of the intermediate portion of 11b is made substantially the same as T, and the upper portion 2 of the intermediate portion 2b ... 11b of each head 2a ... 11a
c, 3c ・ ・ ・ 11c upper wall thickness W1, W2 ・ ・ ・ W11 is made thicker as going from the long iron club A to the short iron club C, so the characteristics of each iron club are fully brought out with the same shot feeling. It will be possible.

That is, the thickness of the intermediate portions of the intermediate portions 2b, 3b, ... 11b of the heads 2a, 3a, ... The elastic deformation (vibration characteristics) with respect to is similar, and it is possible to obtain almost the same shot feeling in each iron club.

Also, the upper part of the intermediate portion 2b ... 11b of each head 2a ... 11a
2c, 3c ・ ・ ・ 11c upper wall thickness W1, W2 ・ ・ ・ W11 became thicker as going from the long iron club A to the short iron club C, so the long iron club A has a soft feeling and the amount of torsion is large. It becomes a ball streak that is large, has high spin, and has a small amount of spin.

On the other hand, in the short iron club C, the amount of torsion is small, the spin is large, the ball stripe at the beginning of the ball is low, the ball rises near the falling point, and the ball stops well when falling. become.

In the embodiments described above, the head thickness of each iron club is different, but the present invention is not limited to such an embodiment. For example, a long iron club may be used. Of course, the thickness may be the same in the middle iron club and the short iron club.

[Effect of device]

As described above, in the golf club set of the present invention,
The thickness of the middle part of the middle part of each iron club is almost the same, and the upper part of the upper part of the middle part of each head is thicker as going from the long iron club to the short iron club. There is an advantage in that the characteristics of each iron club can be fully brought out with the shot feeling.
