Description
BACKGROUND OF THE INVENTION
[0001] 1. (a) Field of the Invention
[0002] The present invention relates to an improved structure for
the club head, and in particular, a club head which improves the
impact force on a golf ball.
[0003] 2. (b) Description of the Prior Art
[0004] FIG. 1 shows a conventional club head of a wooden shaft and
the club head 1 is normally hollow. In order to produce long
distance during impact with a golf ball, the club head is made into
a bigger size, but, due to its hollow structure, the wind
resistance during swinging cannot be controlled, as a result, the
direction of ball-impact and distance cannot be controlled.
[0005] As shown in FIG. 2, the impact face board 11 of the club
head during impact with a golf ball will cause a depression. The
formation will affect the 15 impact force. In order to solve this
drawback, titanium alloy or stainless steel is used for the making
of the club head. However, the thickness of the club head will
increase. FIG. 3 shows a wooden club head by having a ball impact
face board 11 with a inner edge extended to a flat board 2. The
flat board is connected to the long axle of the impact face board
11. As shown in FIG. 4, the flat board is extended at the rear
lateral side to the lower edge of the rear board 12. The flat board
2 can increase the compression strength of the impact face board
11. However, in view of the above-mentioned design, the flat board
2 will increase the weight of the club head and it will not provide
a long distance during impact with a golf ball.
[0006] Accordingly, it is an object of the present invention to
provide an improve structure for the club head of a wooden club,
which mitigates the above drawbacks.
SUMMARY OF THE INVENTION
[0007] Accordingly, it is an invention to provide an improve
structure for the club head of a wooden club, wherein the inner
lateral side of the ball impact face board is provided with a
plurality of cylindrical bodies and one cylindrical body is
extended to the bottom edge of the rear lateral side of the club
head so as to enhance the strength of compression of the ball
impact face board and in turn improve the objective of impact force
of the club.
[0008] Yet another object of the present invention is to provide an
improve structure for the club head of a wooden club, the top edge
of the inner lateral side of the ball impact face board is provided
with a rib, such that when the thickness of the impact face ball is
reduced, the strength of the compression of the impact face ball is
increased.
[0009] The foregoing object and summary provide only a brief
introduction to the present invention. To fully appreciate these
and other objects of the present invention as well as the invention
itself, all of which will become apparent to those skilled in the
art, the following detailed description of the invention and the

DETAILED DESCRIPTION OF THE PRESENT INVENTION
[0017] For the purpose of promoting an understanding of the
principles of the invention, reference will now be made to the
embodiment illustrated in the drawings. Specific language will be
used to describe same. It will, nevertheless, be understood that no
limitation of the scope of the invention is thereby intended,
alterations and further modifications in the illustrated device,
and further applications of the principles of the invention as
illustrated herein being contemplated as would normally occur to
one skilled in the art to which the invention relates.
[0018] Referring to FIG. 5, there is shown an improved structure of
the club head of a wooden club, wherein the inner lateral face of
the ball impact face board 3 of a club head 3 is provided with a
plurality of cylindrical bodies 41 respectively connected at one
point at the impact region on the club head. In order to reduce the
weight of the cylindrical bodies 41, the plurality of cylindrical
bodies 41 are extended and connected at one connection point on the
center of the club head, and an another cylindrical body 42 is
extended to the bottom edge of the rear board 32 of the club head
32 and is mounted at the inner lateral face of the bottom edge.
Next, the top edge of the inner lateral side of the ball-impact
face board and the continuation region of the inner side of the top
board 33 of the club head, a plurality of ribs 5 are spacingly
mounted. The ribs 5 are extended from the impact face board 31
upward to the top board 33 and the rib 5 is an L-shaped structure.
Thus, the strength of the ball-impact face board 31 is
enhanced.
[0019] Referring to FIGS. 5 and 6, the cylindrical bodies 41 can be
either in cylindrical shape or cornered cylindrical shaped body.
The cylindrical body allows the impact face board, at the instance
of impaction, to withstand the weight of the impact ball without
bending. The material of the cylindrical bodies is metal, and the
metal having a preferable strength but lighter is the best. This
will improve the strength of the cylindrical bodies 41, 42 and the
total weight of the cylindrical bodies is reduced. As shown in FIG.
5, the number of the cylindrical bodies 41 is preferable five, and
one of the cylindrical bodies, 41 is connected at the center point
of the impact face board and the other four bodies are respectively
connected at the impact region. The connection point of the
cylindrical bodies 41 is formed from a four point of the impact
force. Besides, the compression of the ball-impact face board 31 is
enhanced. In actual fact, two cylindrical bodies can be used,
however, the strength and the weight factors have to complied with
the above. As shown in FIG. 6, in order to upgrade the strength of
the cylindrical bodies 41 and to control the total weight of the
cylindrical body, the cylindrical body 41 and the other four bodies
are extended to the rear side of the club head and are connected at
the center of the club head. The cylindrical body is extended
toward the rear side of the club head to form a cylindrical body 42
and is connected at the lower edge of the rear board 32. This will
reduce the total weight of the cylindrical body and to reduce the
center of gravity of the club head.
[0020] When the total weight of the club head is to be reduced and
the club head has to be in a larger size, the thickness of the club
head has to be reduced. In this case the compression strength of
the impact face board 31 will become weaker and the connection
strength of the top board 33 and the bottom board 34 is poor. As
shown in FIG. 7, the connection edge of the bottom board 34 is
relatively smaller and the effect will be lesser. The connection
edge of the impact face board 31 and the top board 33 is provided
with the L-shaped ribs 5, and as shown in FIG. 5, the ribs 5 are
spacingly arranged.
[0021] In view of the above, the thickness of the impact portion of
the club head is reduced and a plurality of cylindrical bodies 41,
42 and ribs are used to supplement the connection strength of the
impact face board and the top board. The compression strength of
the impact face board is improved. In accordance with the present
invention, by the application of the cylindrical bodies and the
ribs will increase the volume of the club head by reduce the center
of gravity of the club head. This will increase of distance of
impact of ball.
[0022] It will be understood that each of the elements described
above, or two or more together may also find a useful application
in other types of methods differing from the type described
above.
[0023] While certain novel features of this invention have been
shown and described and are pointed out in the annexed claim, it is
not intended to be limited to the details above, since it will be
understood that various omissions, modifications, substitutions and
changes in the forms and details of the device illustrated and in
its operation can be made by those skilled in the art without
departing in any way from the spirit of the present invention.
