TWO-PIECE TYPE WOOD GOLF CLUB HEAD
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, such as aluminum alloy, magnesium alloy, fiber reinforced resin, or plastic, with a specific weight less than three. The shock-absorption member includes a crown and a neck. The face member is made of a heavy material, such as titanium alloy, or stainless, or Maraging steel, with a specific weight greater than four. The face member includes a face and a sole.
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.
SUMMARY OF THE INVENTIONThe 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.
As shown in
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.
There are a slot 22 and a protrusion 33 on the shock-absorption member 20 and the face member 30 respectively for combination of the shock-absorption member 20 and the face member 30. The places of the slot 22 and the protrusion 33 may be switched that may combine the shock-absorption member 20 and the face member 30 also.
The face member 30 has a gap 34 on a toe and a heel respectively rather than the protrusion 33 that the shock-absorption member 20 and the face member 30 will not be engaged at the gaps 34. This will be advantageous to the combination of the shock-absorption member 20 and the face member 30.
As shown in
A face member 30 of the second preferred embodiment provides bores on a sloe 35 thereof. In
The wood golf club head of the present invention provides the face member with flexible and wear-proof properties for hitting ball and the shock-absorption member with light and shock absorption properties to reduce the shock of hitting ball transferring to player's hand through the neck and a shaft and to shift the center of gravity of the wood golf club head to a bottom and rear portion.
The description above is a few preferred embodiments of the present invention and the equivalence of the present invention is still in the scope of the claim of the present invention.
Claims
