Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a head of a golf club.

(Prior Art) In the head of a conventional golf club, the head body is made of wood or synthetic resin, and metal face plates and sole plates are attached to the face surface and the sole surface so as not to damage or wear them. .

(Problems to be solved by the invention) In the conventional head, a metal face plate or a sole plate is attached to a wood or synthetic resin head main body by screwing or bonding with an adhesive. Therefore, the production is extremely troublesome, and there are problems such as peeling due to repeated hitting of the ball, water entering from the gap, and cracking of the head. Also, if the face plate is thin, it will warp due to the ball hitting, and if it is thick, the weight of the entire head will increase and it will be difficult for women to use, and the center of gravity will also rise, so the ball will often fall off the sweet spot, and the ball will rebound. There is a problem that the force is small and the flight distance is short, and the flight direction is different from the target direction.

In order to solve such a problem, the present invention reinforced the periphery of the face plate and the sole plate, firmly fixed the face plate and the sole plate to the head body, and hit the face plate out of the center. It is intended to provide a head of a golf club in which the ball can fly in the target direction and the flight distance can be extended even when the golf ball hits.

(Means for Solving the Problem) In order to achieve the above-mentioned object, the present invention has a face plate and a sole plate connected to each other, and an appropriate number of wide tabs with wide tips project from the periphery of the face plate and the sole plate. The face-sole integrated plate is punched out from the stainless steel plate, the periphery of the face-sole integrated plate is bent at a substantially right angle with the ear piece to form a brim, and the face plate and the sole plate are curved to the predetermined face curved surface and sole curved surface, respectively. Then, the face groove (score line) is recessed in the face plate by hydraulic press processing, and the face sole metal fittings obtained by bending at the boundary between the face plate and the sole plate are attached to the face surface and the sole surface of the head mold. A head of a golf club, which is obtained by filling a head mold with a synthetic resin after being placed at a corresponding position, and solidifying the synthetic resin in a state in which a collar and an ear piece are buried.

(Function) The face plate and the sole plate are connected, and the collar plate and the ear plate are provided at a substantially right angle on the face plate and the sole plate.The flange and the ear plate are buried in the synthetic resin that constitutes the head body. Since the tip of the ear piece is wide, the face plate and the sole plate do not peel off or deform even if a strong hit is repeatedly performed. Conventionally, the face plate and the sole plate were made separately and attached separately, so the impact of the ball received by the face plate is not transmitted to the sole plate, and the face plate of the face plate is momentarily dented, If is the center of the face plate, the ball flies in the direction of the target, but if the ball is hit at a place outside the center of the face plate, the ball deviates from the target and flies in the wrong direction. However, in the present invention, a flange is formed on the peripheral edge of the face plate in a direction substantially perpendicular to the face surface, and since the sole plate is also connected, the impact at the time of hitting is transmitted to the flange and the sole plate,
The brim and the sole plate work to reinforce the face plate, and the dents prevent the momentary dents generated in the face plate from moving away from the center of the face plate. Therefore, the hit ball at a position outside the center of the face plate does not change its direction easily as in the conventional case, but it can fly at a nearly normal angle, so that the so-called sweet spot spreads. Since the face plate is made of stainless steel and the face groove (score line) is recessed by hydraulic press working, the vicinity of the face groove is hardened due to work hardening, resulting in good ball breakage when hitting and repulsion force. To increase the flight distance.

In the present invention, since the sole plate has the brim and the ear piece on the periphery, the periphery is heavier than the center and the moment of inertia is large.
The direction of the hit ball is stabilized.

As described above, in the head of the present invention, not only the face plate and the sole plate securely protect the face surface and the sole surface of the head, but also the direction stability of the hit ball can be improved and the flight distance can be increased, and the head is inexpensive. Can be manufactured.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

Reference numeral 1 is a synthetic resin head main body, 2 is a face sole metal fitting made by punching out a stainless steel plate, and a face plate 3 and a sole plate 4 are connected to each other and bent at a boundary 5. The face plate 3 is formed into a predetermined face curved surface, a face groove (score line) 3a is concavely formed on the surface by hydraulic press working, and a peripheral edge is bent inward at a substantially right angle to form a flange 6, and the flange 6 is formed. A T-shaped ear piece 7 is projecting at 6. Sole plate 4
Is formed into a predetermined sole curved surface, and a rim 8 is bent inwardly at a substantially right angle to form a brim 8, and a T-shaped ear piece 9 projects from the brim 8. Insert the face-sole metal fitting 2 into the head mold (not shown), locate the face plate and the sole plate at the face part and the sole part inside the mold, respectively, and fill the mold with synthetic resin to make the head body. To be Tsuba 6,8 and ear pieces
7, 9 are buried in the synthetic resin, and the face plate 3 and the sole plate 4 are firmly integrated with the head body 1 by the solidification of the synthetic resin.

The ear pieces 7 and 9 are shaped as shown in FIG. 6 (a),
Alternatively, the tip may be bent as shown in (b), or the tip may be circular as shown in (c) (Effect of the Invention) Since the present invention is configured as described above, the structure is simple and inexpensive. It can be mass-produced, the weight is not heavy, the head is sufficiently protected, and the flight direction can be stabilized and the flight distance can be increased.
