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 wood golf club head.
[0003] 2. Description of the Related Art
[0004] A conventional wood golf club head has a hollow housing
which a center of gravity is positioned at bottom and rear as
possible. In such point, a crown, which is a top potion of the
housing, is made as thinner as possible. The conventional crown is
made of a metal, which is too heavy to make the center of gravity
of the golf club head at bottom and rear. In the present days,
there is a crown made of composite material, which the composite
material is lighter in weight, so that the center of gravity of the
golf club head is positioned lower.
[0005] The only problem of the composite material crown is that how
to couple the crown to the metallic housing in a firm
condition.
SUMMARY OF THE INVENTION
[0006] The primary objective of the present invention is to provide
a golf club head, which the center of gravity thereof is lower.
[0007] The secondary objective of the present invention is to
provide a golf club head, which has a well performance in
absorption of vibration.
[0008] According to the objectives of the present invention, a golf
club head has a metallic head housing and a nonmetallic crown,
wherein the head housing has a face, a sole, a heel, a .toe and a
neck and is open at a top thereof, and the crown is coupled to the
top of the head housing. The crown has two arms coupled to the heel
and the toe of the head housing respectively whereby the crown and
the head housing are coupled together in a firm condition.
[0009] In addition, the head housing is provided with two gaps
respectively at the heel and the toe. The gaps are extended from
tops of the heel and the toe to where adjacent to the sole, or to
the sole. The arms of the crown shield the gaps respectively. With
such structure, the golf club head is lighter such that the head
can be made into a greater size or can be mounted with more weight
devices at the sole to adjust the position of the center of
gravity. Furthermore, the crown can be made of a composite
material, such as reinforced fiber resin, so that the crown is
lighter in weight and has a well elasticity. While the face is
hitting a ball, the crown is deformed elastically to prolong the
time of the face contacted with the ball, such that the golf club
head will have well properties of ball control and absorption of
vibration.

[0010] FIG. 1 is a perspective view of a first preferred embodiment
of the present invention;
[0011] FIG. 2 is an exploded view of the first preferred embodiment
of the present invention;
[0012] FIG. 3 is a sectional view along the 3-3 line of FIG. 1,
and
[0013] FIG. 4 is an exploded view of a second preferred embodiment
of the present invention.
DETAILED DESCRIPTION OF THE INVENTION
[0014] As shown in FIGS. from FIG. 3 to FIG. 5, a golf club head 10
of the first preferred embodiment of the present invention
comprises:
[0015] A metallic head housing 20 has a face 21, a sole 22, a rear
23, a toe 24, a heel 25, and a neck 26. The head housing 20 is
hollow and has an opening at a top thereof. Around the top of the
head housing 20 is an annular shoulder portion 27 and at the toe 24
and the heel 24 is a gap 28 respectively. The gaps 28 are extended
downwardly from the shoulder portion 27 to the toe 24 and the heel
24 at where adjacent to the sloe 22 respectively.
[0016] A nonmetallic crown 30, which is made of carbon fiber
prepreg epoxy resin, or other fiber reinforced resin or plastics in
the present preferred embodiment, has two arms 31 at opposite sides
thereof. The crown is a thin plate to be coupled to the top of the
head housing 20, in which the shoulder portion 27 is attached to a
bottom of the crown 30 and the arms 31 of the crown 30 are attached
on the toe 24 and the heel 24 to shield the gaps 28
respectively.
[0017] In assembly, glue is provided to the shoulder portion 27 and
sidewalls of the gaps 28 of the head housing 20 to stick the crown
30 thereon.
[0018] The arms 31 serve like a clip to hold the crown 30 on the
head housing 20 and make the crown 30 having more portions to be
stuck with the head housing 20 so that the crown 30 is coupled with
the head housing 20 in a firm condition, even the golf club head of
the present invention has been used for a long time, the crown is
not loose.
[0019] In addition, the crown of the present invention is made of a
composite material, which is lighter in weight, and that makes the
golf club head has a center of gravity at lower.
[0020] The golf club head 10 of the present invention has gaps
between the face 21 and the rear 23, and in the gaps 28 are filled
with the arms 31 of the crown 30. While the face 21 is hitting a
ball (not shown), the impact will transmit the arms 31 first and
the composite material arms will absorb the impact to make the golf
club head 10 of the present invention has a well property of
absorption of vibration.
[0021] As shown in FIG. 5, a golf club head 40 of the second
preferred embodiment of the present invention is consisted of a
metallic head housing 50 and a nonmetallic crown 60. The
differences of the second preferred embodiment from the first
preferred embodiment are that the head housing 50 has two gaps 51
are extended to a sole 52 thereof and has a plurality of holes 54
at a rear 53 thereof. The crown 60 has two arms 61 to shield the
gaps 51 respectively and a tail 62 to be coupled to the rear 53 to
shield the holes 54. In such structure, more weight of the golf
club head 40 is reduced to make the designer has less limitation in
the design of the golf club head.
