摘要:
An iron golf club head having a sole and a hosel molded integrally as a frame from a metallic material, a core portion disposed in an upper part above the sole and the outer periphery of the core portion and the outer periphery of the frame except for the sole are covered with a fiber-reinforced resin and a weight having a greater specific gravity than the metallic material of the frame disposed between the sole and the core portion. The weight consists of a mass of 92 to 98 wt. % of powdery tungsten mixed in a polyamide resin.
摘要:
This invention relates to a wood golf club and its production method, wherein an outer peripheral surface recessed from an outer surface of a club head main body through a step is formed on a neck portion of a club head made of a fiber-reinforced resin, a long-fiber-reinforced resin layer formed by winding resin-impregnated long fibers in such a manner as to cross the axial direction of the neck portion is fitted over the outer peripheral surface, and the outer surface of the long-fiber-reinforced resin layer and the outer surface of the club head main body are at substantially the same level.
摘要:
A golf club wherein at least the surface of the face of a club head made of fiber-reinforced plastic or wood or the surface of a club shaft made of fiber-reinforced plastic is covered with a cured coating layer of a silicone-modified synthetic resin.
摘要:
A golf club head in which a core buried in the interior of an outer shell of a fiber reinforced resin is molded out of a molten mixture of a thermoplastic resin and powder of a metal having a high specific gravity, and a method of manufacturing such golf club heads.
摘要:
A wood-type golf club head molded from a fiber-reinforced resin having at least one fin equipped with at least one hook fixed by brazing to the inner side surface of the metal sole plate so that the fiber-reinforced resin of the head will flow into and under the hook of the fin during molding to securely bond the club head to the sole plate.
摘要:
A metal mold for producing a wood type golf club head, including an upper metal mold member having a molding recess including a surface for molding an upper end portion of a shaft bore in a club head, a lower metal mold member having a molding recess including a surface for molding a sole of the club head, a shaft bore molding upper pin fitted firmly in the portion of the surface of the upper metal mold member which corresponds to an upper end portion of the shaft bore, so as to project to the inner side of the metal mold, and a shaft bore-molding lower pin fitted firmly in the lower metal mold member so as to project to the inner side of the metal mold, the upper and lower pins being arranged coaxially in an opposed state via a narrow clearance, the direction in which the upper and lower pins are arranged crossing perpendicularly the direction in which the joint surfaces of the upper and lower metal mold members extend.
摘要:
An iron-type golf club set includes three club groups; a long iron-type club group comprising a plurality of long iron-type clubs having lower club numbers, a middle iron-type club group including a plurality of middle iron-type clubs having medium club numbers, and a short iron club group including a plurality of short iron-type clubs having higher club numbers. The long iron-type clubs of the long iron-type club group each includes a club head which contains a sole made of a metal material and a shell having a ball-hitting face and a core which is made of a foaming material and enclosed in the shell, and the shell is made of a fiber-reinforced material. The middle iron-type clubs of the middle iron-type club group each includes a club head having a sole and an external periphery each made of a metal material and at least a ball-hitting face made of a fiber-reinforced resin. The short iron-type clubs of the short iron-type club group each includes a club head made of a metal material.
