Problems solved by technology

[0006] However, in the golf club head described in Patent Document 1, a low-rigidity and easy-to-bend crown portion is generally formed inside a region called the crown surface. Only this portion is relatively easy to deform, and it is difficult to obtain a side s

Abstract

The invention discloses a golf club head, wherein based on the elastic deformation of the top surface of the club head, the hitting angle is ensured to be larger than the inclination of the club while the backspin momentum applied on a golf ball is reduced so as to prolong the flight distance of the golf ball. The golf club head is provided with a bottom surface forming part (17) used for forming the bottom surface (11) of the golf club head, a top surface forming part (18) used for forming the top surface (12) of the golf club head, and engagement parts (30A, 30B and 30C) formed from the top side (P1), the back side to the central heel side (P4) of the golf club head so as to be positioned within the 1/4-1/2 range of the height of the golf club head. In this way, the central part of the top surface (12) of the golf club head is bent in an expansion manner, so that the inclination of the ball surface is increased temporarily and the hitting angle is increased temporarily.

Description

technical field [0001] The present invention relates to a golf club head, and more specifically, to a golf club head capable of reducing (optimizing) the amount of backspin of the ball when hitting the ball, increasing the launch angle, and extending the flight distance. Background technique [0002] In order for the golf ball to fly farther, it is not only necessary to increase the speed of the club head, but also to have a square club face and use the sweet spot to catch the ball, and the amount of backspin and launch angle of the ball are also factors for extending the flight distance. [0003] For example, if the amount of backspin is too large, the ball will become a bouncing (rapidly rising) trajectory, and after reaching the highest point, it will drop rapidly, causing a greater loss of distance. The same is true for the launch angle. If the launch angle is too large, the ball will reach the highest point in a short time and then drop rapidly, resulting in a greater l...
