Embodiment Construction

[0024] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0025] In the drawings, an iron-type golf club head 1 according to the present invention has a face 2 for hitting a ball, a top surface 3 intersecting the face 2 at an upper portion of the face edge, and a lower portion of the face edge. A sole surface 4 that intersects the face 2 , and a toe surface 5 that intersects the face 2 at the toe side of the edge of the face and extends between the top surface 3 and the sole surface 4 . The top surface 3 slopes downward from the toe towards the heel. The main part of the bottom surface 4 extends substantially horizontally in the toe-heel direction. The toe surface 5 is curved so as to be convex toward the outside. The club head 1 includes a heel portion 6 having an upwardly protruding tubular hosel portion 7 and a shaft insertion hole 7a for inserting a shaft (not shown) therethrough.

Abstract

An iron-type metal golf club head comprises: a main body including a hosel portion and a face plate portion having a back surface and a front surface forming a clubface; and a ring-shaped member disposed behind the face plate portion and having an outer periphery surface continuous in the circling direction of the ring. The ring-shaped member is made up of at least two segments parted by at least two parting planes, each parting plane extending crosswise to the circling direction of the ring-shaped member so as to form opposed sections of the adjacent segments. The segments include: a primary segment attached to the main body by welding along a first line and at least one of second lines; and a secondary segment attached to the main body by welding along the first line, wherein the first line is an intersection line of the above-mentioned outer periphery surface and the surface of the main body, and the second line is an intersection line of the back surface of the face plate portion and each of the sections of the segment.

Description

technical field [0001] The present invention relates to an iron-type golf club head and a method of manufacturing the same, and more particularly to a segmented structure of a ring member disposed behind the face and a method for welding the segment to the body of the club head. Background technique [0002] In Japanese Utility Model Patent 3,114,961, as shown in Fig. 11(a) and Fig. 11(b), there has been proposed an iron type golf club head (A1) comprising a body (a) with a flat back (b) , and an annular member (c) welded to the back face (b) to form an opening (e) behind the face. [0003] In this club head structure, the interface between the main body (a) and the ring member (c) is shown as a joint line (Bo) on the outer peripheral surface of the club head, and on the inner surface of the cavity (e) Above is shown as the bonding wire (Bi). Then, there is the possibility to carry out the welding operation along the bonding wire (Bo) and the bonding wire (Bi). [0004] W...
