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 surface of the club head. There is still room for improvement in terms of sufficient deformation for the deformation of the state brought in by the side
In addition, due to the use of resin materials, there is a problem in strength along with making it low rigidity

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. More specifically, it relates to a golf club head capable of reducing (appropriate) the amount of backspin of the ball when hitting a ball and increasing the angle of shot, thereby extending the flight distance. Background technique [0002] Needless to say, in order to make the golf ball fly farther and speed up the head speed, it is also necessary to square the club face and use the sweet spot to catch the ball. The amount of backspin and the angle of the ball are also factors used to extend the flight distance. [0003] For example, if the amount of downspin is too large, the ball will become a bouncing (rapidly rising) trajectory, and after reaching the highest point, it will fall rapidly, causing a greater loss of distance. This is the same for the shot angle. If the shot angle is extremely large, the ball will reach the highest point in a short time and then drop rapidly, making the distance loss greate...
