Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for forming the face of a Colts club '\7.1, commonly known as Wood, Dryno, etc., and particularly relates to a method for forming the face of a genuine corf club such as Persimmon. MonodeΔ)ru.

Traditionally, Persimmon's wooden Kolfukushisopa No. 1-
In order to protect the direct ball hitting surface of the club face from ball impact or damage,
It has a structure in which a face plate 1-, which consists of a separate part from the throat body, is attached.

Such conventional golf clubs have the following problems.

In other words, when hitting a ball placed on the teeing ground, etc., it is fine as long as the ball is reliably hit in the face play area, but it is sufficient to hit the ball in the face play area.
Players who are not accustomed to setting the ball address often end up hitting the ball with a part of the face other than the fly or spray plate. If this kind of thing is repeated, dents or scratches will occur on the surface of the face part other than the face plate, which is made of the same material as the throat body, resulting in an extremely unsightly club face and shortening the life of the product. Cause. In particular, a ball with a high surface hardness, called a two-piece hole, is used with great advantage.11. Nowadays, the degree of occurrence of dents and damage on the surface of face parts other than face play 1- has become obvious.

Also, in order to prevent damage to the face parts other than face play I~, it is possible to have a structure where the entire club face is covered with a face plate, but this is...
In addition to damaging the features of Persimmon golf clubs, such as destroying the weight balance of the throat body and moving the center of gravity toward the face, it also impairs directionality. There is a problem in that it becomes difficult to properly align the position of the club face with the sweet spot and throat.

The present invention provides a method for molding the face of a club head made of wood such as Persimmon, which solves the above-mentioned problems. This makes it possible to prevent damage, which in turn simplifies the moldability of the face, and facilitates the setting of the address of the club head relative to the ball.

EMBODIMENT OF THE INVENTION Hereinafter, a specific example of the method for molding a face of a golf club head according to the present invention will be described based on the drawings.

Figure 1 (al~(cl) shows an example of the method for forming a throat face according to the present invention. First, as shown in Figure 1 (a), the metal body 1 is put into a club made of ice phase such as vershimon. On the face 2, a circular concave portion 4.5 of a desired diameter is formed to a desired depth by 1-' drilling so as to be closer to the toe 1a and heel 1b side. A disk-shaped auxiliary face plate 6.7 having the same volume as 1 is press-fitted as shown in FIG.

The auxiliary face plate 6.7 is made of, for example, a synthetic resin-impregnated material (hardness: 100.8 mm, specific gravity: 1, i
9) Or stack many reinforcing fiber sheets such as carbon 1i
solidified with a synthetic resin phase (hardness 121
．． 3mm, specific gravity 1.72), etc.
Persimmon (hardness 32.1 mm) that molds the head body 1
, specific gravity 0.68), etc., which is harder than the peripheral part and less likely to cause dents and damage, and the specific gravity is almost the same as the base material of the throat body 1.

After the installation process of the auxiliary face plate 6.7 is completed, a front shape extending from the top IC of the head body ■ to the sole 1d is attached to the central part of the club face 2 of the head body 1, as shown in FIG. 1 (e+). A trapezoidal face plate 1/mounting step 8 is formed by milling or the like.This step 8 overlaps a part of the auxiliary face plate 6.7, and the horizontal W1 of the step 8 The shape is a dovetail groove.After that, a large number of strong fibers such as carphones are laminated to a desired thickness of 6 io,), which is solidified using a synthetic JM fat mill, and a stand is formed from one piece. Insert the shaped face plate 9 into the stepped portion 8 of the sole 1.
Press in from d and adhere with adhesive (see 2nd page)
. Next, the face surface i after attaching the face plate 9
After finishing the face, grooves (face lines) 10 are carved on the finished surface. This completes the molding of the club face 2a.

In the club face 2a of the throat body 1 formed as described above, the toe 1d and heel i b of the head body 1 (the face portion adjacent to the jill is almost the same as the head body 1) sandwiching the face plate 1-9. With the same specific gravity,
Moreover, the auxiliary face spray 1-6 is made of 4A quality, which has a higher hardness. 'N Due to the awkward structure, the auxiliary face plate 6.7 has been removed from the face plate 9.
Even if the ball is hit in this area, dents and scratches are less likely to occur, and the quality of the gutter body 1 can be maintained over a long period of time, and the weight tolerance of the head body 1 does not change. , without detracting from the characteristics of wooden clubs such as Persimmon. Furthermore, by making the recess into which the auxiliary face plate 6.7 is embedded a simple circular hole, the machining of the gutter body 1 and the gutter body 1 becomes simple and highly productive. Furthermore, if the auxiliary face plate 1-6.7 and the face plate 9 are color-coded, the existence of the face plate 9, which falls over the face 2, will stand out visually, and this will make it easier to swing towards the club. When addressing the throat body 1 to the rear of the ball, the club face 2 should be oriented toward the ball flight line, or can be quickly changed direction, and the position relative to the pole of face plays 1 to 9 should be 61. It also becomes easier to set up.

FIGS. 3(a) to (C1) show other embodiments of the face forming method of the present invention. First, as shown in FIG. Attach it to the center part, and then attach it to the tops 1a and 5 of the club face 2 with the parts of the face plates 1 and 9 as shown in (b).
b (,!J) to form a circular concave Hl!4.5, and an auxiliary face plate 1-6.7 of the same shape as this is shown in Fig. 3 FC+ in each of the four parts 4 and 5. Press-fit into the hole and attach with adhesive.

In this embodiment, in addition to obtaining the same effect as in the embodiment described in 1) above, the pattern of Tough Fufu L-S 2 is shaped like 4 dogs or erect, and the image of Crappa No. 〃The fruit is turned. This is also the same in the examples.
