A golf club head includes a front member, a rear member and a neck connected together to form a housing. The front member, which is made of a flexible material, such as aluminum alloy, stainless or Maraging steel, has a face and an annular wall projected from a back of the face to form a cup-like member, wherein the wall has a connecting portion at a distal end thereof, and a length of the wall is identical to or greater than 8 mm and a thickness of the wall is identical to or less than 2 mm. The rear member, which is made of a light metal, such as magnesium alloy or aluminum alloy, has a connecting portion to engage the connecting portion of the front member. The neck is fixed on the rear member.
Description
- 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
- A golf club head, which a housing thereof is made of magnesium alloy or aluminum alloy, has many advantages, such as light weight, greater size and lower center of gravity. Especially for a magnesium alloy golf club head, it has a superior vibration absorbing capacity. But, magnesium alloy has a weak strength that is not suitable for the face. To overcome this issue, the face is usually made of the alloy with superior flexibility, such as titanium alloy or stainless. However, magnesium alloy or aluminum alloy has a lower melting temperature than titanium alloy and stainless, so that the titanium alloy or stainless face can't bond to the magnesium alloy or aluminum alloy housing by brazing or other conventional welding. Such golf club head usually has a weal bonding strength between the housing and the face because that the housing and the face are made of different materials.
- The primary objective of the present invention is to provide a golf club head, which a housing made of magnesium alloy or aluminum alloy and a face made of titanium alloy or stainless have a strong bonding strength therebetween without the drawback as described above.
- According to the objectives of the present invention, a golf club head includes a front member, a rear member and a neck connected together to form a housing. The front member, which is made of a flexible material, such as aluminum alloy, stainless or Maraging steel, has a face and an annular wall projected from a back of the face to form a cup-like member, wherein the wall has a connecting portion at a distal end thereof, and a length of the wall is identical to or greater than 8 mm and a thickness of the wall is identical to or less than 2 mm. The rear member, which is made of a light metal, such as magnesium alloy or aluminum alloy, has a connecting portion to engage the connecting portion of the front member. The neck is fixed on the rear member.

FIG. 1 is a perspective view of a first preferred embodiment of the present invention; -
FIG. 2 is a sectional view along 2-2 line ofFIG. 1 ; -
FIG. 3 is an enlarged view of the circle inFIG. 1 ; -
FIG. 4 is a bottom view ofFIG. 1 ; and -
FIG. 5 is a sectional view of a second preferred embodiment of the present invention. - As shown in
FIG. 1 toFIG. 4 , agolf club head 10 of a first preferred embodiment of the present invention includes afront member 20 and arear member 30. - The
front member 20 is made of a flexible material, such as aluminum alloy, stainless or Maraging steel. Thefront member 20 has aface 21 and anannular wall 22 projected from a back of theface 21. Thefront member 20 is a cup-like member. Theannular wall 22 has a connecting portion at a distal end. As shown inFIG. 3 , a length W of thewall 22 is identical to or greater than 8 mm, and a thickness D thereof identical to or less than 2 mm. In the present embodiment, the length is 10 mm, and the thickness D is 1.5 mm. - The
rear member 30 is made of a light material, such as magnesium alloy or aluminum alloy. Therear member 30 is a cup-like member also with a greater depth. Therear member 30 has a connectingportion 31 at an open end to be engaged with the connectingportion 23 of thefront member 20. As shown inFIG. 3 , the connectingportion 23 of thefront member 20 has a protrusion and the connectingportion 31 of therear member 30 has a recess. A thickness S of therear member 30 between an exterior side and therecess 31 is less than 3 mm. In the present embodiment, the thickness S is 1.5 mm. - As shown in
FIG. 4 , at a bottom of thegolf club head 10, thefront member 20 has abottom portion 24 projecting rearwards from a middle thereof, and therear member 30 has a gap or slot to engage thebottom portion 24. As a result, thebottom portion 24 forms a protective portion at the bottom of thegolf club head 10. Thebottom portion 24 may be wider to form the whole bottom of thegolf club head 10 also. It also may provides therear member 30 has an indentation at an exterior side (not shown) and thebottom portion 24 of thefront member 20 is complementary to the indentation, in other words, thefront member 20 and therear member 30 are overlapped at thebottom portion 24. - The
golf club head 10 further includes aneck 11 formed on therear member 30 to provide vibration absorbing capacity. - Adhesive, such as epoxy resin, is added between the connecting
portions rear members - The present invention provides the
front member 20 made of flexible metal, such as titanium alloy or stainless with the length W of thewall 22 greater than 8 mm, more preferable is 10 mm and the thickness D is less than 2 mm, more preferable is between 1.2 mm and 1.5 mm, such that thewall 22 has a superior flexibility to sustain an impact of swing. Thewall 22 has a strain to absorb most of the impact that the connectingportions rear member 30 may be thinner to reduce the thickness and weight at acrown 13 of thegolf club head 10. - As shown in
FIG. 5 , agolf club head 40 of the second preferred embodiment of the present invention includes arear member 50 consisting of an upper member and abottom member 70. Theupper member 60 is made of a light metal with a specific weight less than 3 and vibration absorbing capacity, such as industrial plastic, fiber reinforced resin, magnesium alloy or aluminum alloy, and thebottom member 70 is made of a heavy metal with a specific weight greater than 4 and wear-proof capacity, such as stainless, titanium, iron, wolfram made by powder metallurgy or wolfram-copper alloy, which provides the wear-proof and weight distribution effects. - 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.
