DETAILED DESCRIPTION OF THE INVENTION

[0001]

[Industrial application] This invention is a golf club iron head that is easy to hit and easy to use, good news for golfers who want to reach a distance, those who do not know the direction, and those who want to improve further. A club that offers. Both left-handed and right-handed can be manufactured.

2. Description of the Related Art Since the center of gravity of a conventional iron head is 6: 4 or 7: 3, which is higher than the neck, it is difficult to hit the sweet spot (center of gravity) when hitting. Although the length of the shaft is shortened or the sole is penetrated to the sole to move the center of gravity, there is a risk that the head comes off because the bonding surface between the shaft and the head is reduced. At the same time, it is difficult to adjust the lie angle and loft angle. In addition, when hitting the heel, there is a problem that the heel is caught, which causes the directionality to be lost. When the top line mark is attached to a conventional iron head, the player tends to hit the neck when holding up because the neck is leaned.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in order to eliminate the drawback, and the center of gravity is moved from the conventional position to the center of the face to make it easier to hit the sweet spot. In addition, the resistance between the heel and the turf surface during the swing is eliminated, the direction and distance of the ball are kept stable, and the danger of the head coming off is avoided and safety is ensured.
Enables adjustment of lie angle and loft angle. Also, by marking the top line, it is a mark of the sweet spot, giving the player a sense of security when holding it.

[0004]

Means for Solving the Problems A groove is dug in FIG. 1-2 where a top line diagram 1-4 and a hosel diagram 1-1 intersect.
Like 9 Cut from the heel diagram 6-13 of the sole diagram 6-12 to the bag edge diagram 6-15 as shown in FIG. 6-14. Mark the center of gravity on the top line figure 1-4.

[0005]

The weight of the neck portion (FIG. 1-2) and the heel portion (FIG. 1-7) is reduced by cutting as shown in FIGS. 3-9 and 6-14, and the center of gravity moves to the center diagram (8-18). . Since the center of gravity can be moved in this way, the hosel
By adjusting the length of -1, the center of gravity need not be brought to the center. Further, by cutting as shown in FIG. 6-14, the contact portion with the grass surface is reduced. Top line figure 1
-4 is marked cheaper if you attach the center of gravity mark 1-3.

[0006]

[Embodiment] The center of gravity of the entire head is at the center of the face.
When the ball hit 8, the ball hit the sweet spot more easily and the flight distance increased. Also, since the contact with the turf surface of the sole shown in FIG. 6-12 is reduced, the disadvantage that the heel gets stuck on the turf surface when hitting is eliminated, and the advantage that the directionality of the ball is stabilized is also produced. Since the hosel can be kept long, the mounting method is also safe. Therefore, the lie angle diagram 4-10 and the loft angle diagram 5-11 can be freely adjusted. There is a sense of security when setting up by marking the center of gravity on the top line.

[0007]

As described above, the iron head of the present invention is a golf club that is the easiest and easy to use for golf players. The club is also safe and can be used with peace of mind. It is a revolutionary club not found in conventional models.
