GOLF CLUB HEAD
Abstract
A golf club head includes a head body and a striking plate. The
head body has a front open end, and a limiting rib projecting
inwardly from an inner wall face of the head body and proximate to
the front open end. The limiting rib has two opposite first rib
sections, and two opposite second rib sections interconnecting the
first rib sections. Each second rib section has a thickness smaller
than that of each first rib section. The striking plate covers the
front open end, and abuts against front sides of the first and
second rib sections. The striking plate has a sweet spot closer to
the first rib sections than the second rib sections.

Claims
1. A golf club head, comprising: a head body having a front open
end, and a limiting rib projecting inwardly from an inner wall face
of said head body and proximate to said front open end, said
limiting rib having two opposite first rib sections, and two
opposite second rib sections interconnecting said first rib
sections, each of said second rib sections having a thickness
smaller than that of each of said first rib sections; and a
striking plate covering said front open end and abutting against
front sides of said first and second rib sections, said striking
plate having a sweet spot closer to said first rib sections than
said second rib sections.
2. The golf club head of claim 1, wherein the thickness of each of
said second rib sections is smaller than that of each of said first
rib sections by 0.5 mm.
3. The golf club head of claim 2, wherein said first rib sections
are opposite in a top-to-bottom direction, and said second rib
sections are opposite in a left-to-right direction.
Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] This invention relates to a golf club head, more
particularly to an improvement in a golf club head.
[0003] 2. Description of the Related Art
[0004] Referring to FIG. 1, a conventional golf club head includes
a hollow head body 21, and a striking plate 22 connected to a front
side of the head body 21 for striking a golf ball (not shown). The
head body 21 has a front open end 211, and a looped limiting rib
212 projecting radially and inwardly from an inner wall face of the
head body 21 near the front open end 211 and abutting against the
striking plate 22 so as to limit inward movement of the same.
Because the limiting rib 212 is configured having a uniform
thickness, the conventional golf club head is heavy, so that a
large swinging force is necessary to strike the ball.
SUMMARY OF THE INVENTION
[0005] Therefore, the object of the present invention is to provide
a golf club head that is lighter than the above-mentioned
conventional golf club head.
[0006] According to this invention, a golf club head comprises a
head body and a striking plate. The head body has a front open end,
and a limiting rib projecting inwardly from an inner wall face of
the head body and proximate to the front open end. The limiting rib
has two opposite first rib sections, and two opposite second rib
sections interconnecting the first rib sections. Each of the second
rib sections has a thickness smaller than that of each of the first
rib sections. The striking plate covers the front open end, and
abuts against front sides of the first and second rib sections. The
striking plate has a sweet spot closer to the first rib sections
than the second rib sections.
BRIEF DESCRIPTION OF THE DRAWINGS
[0007] Other features and advantages of the present invention will
become apparent in the following detailed description of the
preferred embodiment of the invention, with reference to the
accompanying drawings, in which:
[0008] FIG. 1 is a fragmentary sectional view of a conventional
golf club head;
[0009] FIG. 2 is an exploded perspective view of the preferred
embodiment of a golf club head according to the present
invention;
[0010] FIG. 3 is a fragmentary sectional view of the preferred
embodiment taken along line III-III of FIG. 2; and
[0011] FIG. 4 is a fragmentary sectional view of the preferred
embodiment taken along line IV-IV of FIG. 2.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0012] Referring to FIGS. 2 to 4, the preferred embodiment of a
golf club head 10 according to the present invention is shown to
comprise a hollow head body 3 and a striking plate 4.
[0013] The hollow head body 3 has a front open end 310, and a
looped limiting rib 32 projecting radially and inwardly from an
inner wall face of the head body 3 and proximate to the front open
end 310. The limiting rib 32 has two first rib sections 321 that
are opposite to each other in a top-to-bottom direction, and two
second rib sections 322 that are opposite to each other in a
left-to-right direction and that are connected respectively to left
and right ends of the first rib sections 321. The thickness of each
second rib section 322 is smaller than that of each first rib
section 321. Preferably, the thickness of each second rib section
322 is 0.5 mm smaller than that of each first rib section 321.
[0014] The striking plate 4 is connected to the front open end 310
of the head body 3 so as to cover the same. The striking plate 4
abuts against front sides of the first and second rib sections 321,
322, and has a sweet spot 40 located at a central portion thereof.
The sweet spot 40 is closer to the first rib sections 321 than the
second rib sections 322. Since the sweet spot 40 is farther from
the second rib sections 322, the reduction in the thickness of the
second rib sections 322 does not affect the ball-striking effect of
the golf club head 10. Rather, the weight of the golf club head 10
is reduced, and the center of gravity of the entire golf club head
10 is moved rearward. Hence, a golf club using the golf club head
10 of the present invention can strike a golf ball farther and with
less effort during a swinging action.
[0015] From the aforementioned description, it is apparent that
because the second rib sections 322 are provided with a smaller
thickness, the weight of the entire golf club head 10 is reduced
without affecting the striking ability of the golf club head 10. In
addition, the center of gravity of the golf club head 10 is moved
rearward. Hence, a player can swing the golf club with less effort
and can strike the golf ball farther.
[0016] While the present invention has been described in connection
with what is considered the most practical and preferred
embodiment, it is understood that this invention is not limited to
the disclosed embodiment but is intended to cover various
arrangements included within the spirit and scope of the broadest
interpretations and equivalent arrangements.
