Two-piece type wood golf club head

Two-piece type wood golf club head description/claims

1. Field of the Invention

The present invention relates generally to a golf club, and more particularly to a golf club head made of light alloy, such as magnesium alloy or aluminum alloy.

2. Description of the Related Art

Conventional golf club heads have single-piece type, two-piece type or multi-piece type. The single piece type golf club heads usually are made by casting. Typically, the conventional two-piece type wood golf club head consists of a first piece, which is made by casting, with a face, a sole, a toe, a heel, a back and a neck and a second piece with a crown. The first piece is like a cup with an opening at a top thereof and the second piece is like a lid sealing the opening. The second piece is a thin plate to shift a center of gravity of the golf club head to the bottom. Another conventional two-piece type wood golf club head consists of a cup-like first piece with an opening at a bottom thereof and a second piece sealing the opening. The second piece is made of a heavy and wear-proof metal to adjust a center of gravity of the golf club head and make model, logo or other information thereon. The third conventional two-piece type wood golf club head consists of a cup-like first piece with an opening at a front thereof and a second piece sealing the opening. The second piece is a face made of a particular material.

The primary objective of the present invention is to provide a wood golf club head with a light crown, a flexible face, a wear-proof sole and a neck with excellent shock absorption capacity.

According to the objectives of the present invention, a wood golf club head includes a shock-absorption member and a face member connected together. The shock-absorption member is made of a light and shock absorption material with a specific weight less than three including a crown and a neck. The face member is made of a heavy material 1 with a specific weight greater than four including a face and a sole.

FIG. 1 is a perspective view of a first preferred embodiment of the present invention;

FIG. 2 is an exploded view of the preferred embodiment of the present invention;

FIG. 3 is a sectional view along the 3-3 line of FIG. 1; and

FIG. 4 is an exploded view of a second preferred embodiment of the present invention.

As shown in FIG. 1 to FIG. 3, a wood golf club head 10 of a first preferred embodiment of the present invention includes a shock-absorption member 20 and a face member 30.

The shock-absorption member 20 is made of aluminum alloy, magnesium alloy, fiber reinforced resin (like carbon fiber), or plastic, or other suitable material, which is light, shock-absorption material with a specific weight less than three. The shock-absorption member 20 includes a crown 11 and a neck 12 of the wood golf club head 10.

The face member 30 is made of a heavy metal, such as titanium alloy, or stainless, or Maraging steel, with a specific weight greater than four. Typically, the face member 30 is made by casting. The face member 30 includes a face 13 and a sole 14 of the wood golf club head 10. The face member 30 has a wall 32 at a top thereof, which is extended backwardly from the face 13 to make the face 13 as a cup-like member.
