Problems solved by technology

[0003] However, in rainy weather, etc., when water accumulates in the grooves of the face, or when the ball rolls away from the standard trajectory due to a directional hit or a mis-hit, sometimes the ball cannot be given sufficient backspin just by the grooves of the face.

Embodiment Construction

[0045] Hereinafter, a golf club head and a method of manufacturing the same according to an embodiment of the present invention will be described with reference to the drawings.

[0046]

[0047] figure 1It is a view when the golf club head 1 according to this embodiment is viewed from the face 2 side. The golf club head 1 according to the present embodiment is an iron type golf club head. The characteristic groove pattern described later is formed on the club face 2, the main purpose of which is to increase the amount of backspin of the ball, and the same groove pattern can also be applied to golf clubs such as woods and utility types. in the club head.

[0048] Golf club head 1 is made of metal material, such as figure 1 As shown, the golf club head 1 includes a head body portion 3 and a hosel portion 4 integrally provided on the head body portion 3 via a neck portion 9 . The hosel 4 is a cylindrical member into which the shaft of the golf club is inserted. A club fac...

Abstract

A golf club head including a face surface for hitting a ball is provided. The face surface has a plurality of score lines, a first groove pattern, and a second groove pattern. The score lines extend in a toe-heel direction. The first groove pattern is made up of first micro grooves extending along a plurality of first virtual lines. The second groove pattern is made up of second micro grooves extending along a plurality of second virtual lines intersecting the first virtual lines. At least one out of the first micro grooves and the second micro grooves extend as dashed lines interrupted in a vicinity of intersections between the first virtual lines and the second virtual lines, such that the first micro grooves and the second micro grooves do not overlap each other.

Description

technical field [0001] The present invention relates to a golf club head having a club face for striking a ball and a method of manufacturing the same. Background technique [0002] Conventionally, there are known golf club heads in which face grooves and fine groove patterns extending in the toe-heel direction are formed on the face (see Patent Documents 1 to 3). The purpose of forming the face grooves is to increase the amount of backspin imparted to the ball by applying friction to the ball sliding on the face at the time of impact. In addition, in order to maximize this frictional effect, the face grooves are generally formed in a direction that is different from the trajectory of the ball on the face when it hits the ball with a so-called positive face at the sweet spot. (hereinafter, referred to as "standard trajectory") vertical direction. [0003] However, in rainy weather, etc., when water accumulates in the grooves of the face, or when the ball rolls away from th...
