Abstract

(57) [PROBLEMS] To provide a golf club head which has stability when launching a ball from a bunker and does not dug soil or sand together when hitting the ball. SOLUTION: The thickness of the area of the bottom portion 13 of the head 1 is reduced so that the center of gravity 12 on the back side of the ball striking face 11 of the golf club head 1 is located at a position that is at least half the height of the head 1, and then the bottom portion 13 is thinned. Reduce resistance to banks. In the golf club head 1, the center of gravity 12 on the back side of the ball striking face 11 is located at a half or more of the height of the head 1 and the thickness of the bottom portion 13 thereof is thin, so that the ball hit on the bank is hit. Sometimes you can hit the bottom of the ball directly, and because it doesn't hit the sand or soil of the bank at the same time, you can hit the ball upwards into a high trajectory parabola, and after it hits the ground, it doesn't roll too much forward. .

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 A golf club head that facilitates hitting a ball that has fallen on a bunker.

[0002]

[Prior art]

 A type of golf club head used in the past is shown in FIG. 3, and the center of gravity 30 on the back side of the ball striking face 20 is generally half or less of the height of the head. Also, some are in less than three-fifths. When a golf player looks at the golf club head with respect to the ball before hitting the ball on the bunker, the golf player usually adjusts the bottom of the head about one ball or a half distance after the ball 40. As a result, the striking surface 20 of the head 10 and the ground are inclined by about 60 °. Then, when the ball is actually hit, as shown in FIG. 4, the ball 40 is hit upward by digging the bottom of the head under the surface of the bunker 50, and the sand or soil is dug at the same time. Then the ball is hit indirectly. The lower the center of gravity of the head 10, the smaller its swaying motion. However, a general golf player does not pay attention to the drawback of the low center of gravity of the head 10, and if the center of gravity of the head is low, the area of the bottom portion becomes large, so that the area of contact of the head bottom portion with the bunker 50 also becomes large, and thus the head bottom portion becomes large. The resistance between the bunker and the bunker 50 is also increased relatively, so the force when the club hits the ball is subtracted from that resistance and the ball does not reach the expected position. This is a drawback of the head that exists when hitting a ball that has fallen on a bank or a rough surface (high grass).

[Problems to be solved by the device]

 SUMMARY OF THE INVENTION The main object of the present invention is to provide a golf club head which has stability when hitting a ball from a bunker and does not dig up soil or sand together when hitting the ball.

[0004]

Means for Solving the Problems The thickness of the bottom area of the head is reduced so that the center of gravity on the back side of the ball striking face of the golf club head is located at a position that is at least half the height of the head. The resistance between them is reduced. In the golf club head of the present invention, the center of gravity on the back side of the ball striking surface is located at one or more of the half of the height of the head, and the thickness of the bottom is thin, so when hitting a ball that has fallen into the bank It can hit the bottom of the ball directly to the ground, and because it does not launch the sand or soil of the bank at the same time, the ball can be thrown upward into a high trajectory parabola, and after falling to the ground, it does not roll very forward. .

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. As shown in FIG. 1, the golf club head with the improved center of gravity of the present invention has the center of gravity 12 on the back side of the ball striking face 11 of the head 1 at a position not less than ½ of the height of the head 1, Therefore, the thickness of the area of the bottom portion 13 is increased. Therefore, the area where the bottom portion 13 of the head 1 contacts the surface of the bunker 2 is made smaller. As a result, the resistance between the bottom 13 of the head 1 and the bunker 2 becomes smaller.

When a golf player hits a ball 3 with a club head 1 of the present invention from a bunker 2 (or a high grass field or a recessed hole in which grass is dug), a ball hitting surface 11 of the head 1 is placed behind the ball 3. Swing the club so that it tilts about 60 ° to the ground and hit the ball 3. Therefore, the contact point between the ball striking surface 11 of the head 1 of the present invention and the ball 3 is relatively opposite to the contact point of the conventional head and ball, that is, the center of gravity of the ball striking surface 11 of the present invention is higher, Since the center of gravity is lower, head 1 launches ball 3 directly out of the bunker, and the ball striking force exerted on the club is adjusted by the player enough to drop it to the intended point, so ball 3 has a high trajectory. It flies in the air in the form of a parabola and falls to a planned point.

The golf club head of the present invention has the following effects on the ball striking action. Since the center of gravity on the back side of the ball striking surface is higher than half the height of the head, the head can hit the bottom of the ball when hitting the ball and hitting the ball upwards. It can form and fly a high trajectory parabola, drop it to its intended location, and have less distance to hit the ground and roll forward than a ball hit by a conventional low-center-of-gravity club head, so It can be dropped to a more accurate spot.

When the golf club head of the present invention is viewed along the ball before hitting the ball dropped in the bank, the hitting surface is brought close to the center of gravity of the ball, and the high center of gravity of the head and the low center of gravity of the ball are adjusted. By utilizing the relative relationship, it is possible to hit the ball upward in the shape of a parabola at the moment of swinging the club, so that it is not necessary to hit the sand or soil of the bank together with the ball unlike the conventional club head.

Since the golf club head of the present invention hits the ball upward and easily makes the ball fly in the reverse rotation, the ball does not roll forward excessively with inertia after it hits the ground.
