Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] 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.
[0003] 2. Description of the Related Art
[0004] 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 INVENTION
[0005] 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.
[0006] 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.
BRIEF DESCRIPTION OF THE DRAWINGS
[0007] FIG. 1 is a perspective view of a first preferred embodiment
of the present invention;
[0008] FIG. 2 is an exploded view of the preferred embodiment of
the present invention;
[0009] FIG. 3 is a sectional view along the 3-3 line of FIG. 1;
and
[0010] FIG. 4 is an exploded view of a second preferred embodiment
of the present invention.
DETAILED DESCRIPTION OF THE INVENTION
[0011] 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.
[0012] 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.
[0013] 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.
[0014] 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.
[0015] 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.
[0016] As shown in FIG. 4, the second preferred embodiment of the
present invention provides a shock-absorption member 20, which is
made of carbon fiber reinforced resin or plastic, is embedded with
a reinforced metal tube 40 in a neck 12 to enhance the strength of
the neck 12.
[0017] A face member 30 of the second preferred embodiment provides
bores on a sloe 35 thereof. In FIG. 4, it shows that there are two
bores 36 adjacent to a toe and a heel respectively for reduction of
weight. The bores 36 are sealed with plugs (not shown), which are
light materials, such as aluminum, magnesium, plastic, fiber
reinforced resin, or other suitable materials. The face member 30
may be fixed with weight devices (not shown) on the sole 35 for
adjustment of a center of gravity of the wood golf club head
10.
[0018] 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.
[0019] 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.
