Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to an improved golf club
structure, more particularly to an improved golf club structure
that reduces the vibration conducted to the rod when the golf ball
is stricken in order to avoid athletic injury and improve the
accuracy of the direction of striking the golf ball. In the
meantime, the present invention also has the effect of lowering the
noise, improving the accuracy of the direction of striking the golf
ball, and enhancing the strength of the coupling between the club
head and the club stick.
[0003] 2. Description of the Related Art
[0004] In general, a golf club is composed of a club stick and a
club head, wherein the club stick at it upper end further comprises
a handle for the golfer to grip; and the club head is divided into
different types and shapes such as wooden club head, iron club
head, and putter head according to the application of the striking.
Since the wooden club head has better flexibility, therefore it is
generally used for long-distance driving. Most of the iron club
heads are made of alloys or soft steel materials; although these
materials have better rigidity, lower center of gravity, and a
flexibility lower than the wooden club head, yet the iron club head
is generally used for short-distance or mid-distance stroke.
Furthermore, the design with special inclination for the stroke is
very suitable for striking the golf ball in all kinds of angles and
in the poor landform conditions such as in the sand trap and rough.
The putter head is generally made of alloys or soft steel materials
as well, and is generally used for short-distance putt on the
green.
[0005] In general, the material used for the golf club stick
usually adopts hollow copper pipe, glass fiber, carbon fiber, or
other special fiber, etc. The club stick is coupled to the club
head. In other words, both of the club head and club stick are
rigid. Therefore, when the club head hits a golf ball, the strong
vibration wave so produced will be conducted along the club stick
directly to the golfer's hands. According to Newton's third law of
motion, the larger the force of the stroke, the larger is the
reaction conducted to the club stick. The golfer's hand will feel
numb due to the striking of the golf ball. If the golfer cannot
strike the ball with correct pose, it may cause athletic injury
after playing such game for long time.
[0006] Further, the vibration wave produced from striking the golf
ball is an external force, which is conducted to the golfer's hands
along the club stick and will affect the stability of gripping the
club. Furthermore, it will affect the accuracy of the striking
direction. Traditionally, the beginner needs to take a long-time
practice to improve the striking accuracy, and the expenses for the
golf game is higher than other sports. It discourages the beginners
and makes them lose their confidence under the situation of gaining
not much improvement for a long-time practice as well as spending
lots of money.
[0007] In another aspect, the coupling between the club stick and
club head of the golf club is roughly divided into two types: the
first type is to insert the club stick into the insert hole
disposed on the neck section of the club head, and then a
mechanical component such as a twig or a rivet is nailed into the
preset hole of the neck section of the club head and the club
stick; the second type is to use an adhesive such as epoxy resin to
coat the lower end of the club stick and the insert hole of the
club head, and then insert the stick with coated adhesive into the
insert hole of the club head. In the second type, the improved
quality of adhesive can give a good coupling, but the sticky
interface of the club stick may be loosened easily. Thus it will
lower the coupling strength and has the shortcoming of falling
off.
[0008] Therefore, the present invention focuses on the
aforementioned shortcoming of the traditional golf club for the
improvement.
SUMMARY OF THE INVENTION
[0009] The primary objective of the present invention is to provide
an improved golf club structure that can reduce the strength of the
vibration wave conducted to the club stick when the golf ball is
hit to avoid athletic injury and enhance the accuracy of the
direction of striking the golf ball.
[0010] The secondary objective of the present invention is to
reduce the noise generated when the club head hits the golf
ball.
[0011] Another objective of the present invention is to further
improve the coupling strength of the sticky interface when the club
head and the club stick are coupled with adhesive.
[0012] To accomplish these objectives, the present invention
comprises a plurality of openings disposed around the periphery of
the neck section of club head that is connected to the club stick,
such that most of the vibration waves and sound waves produced when
the golf ball is hit will be dispersed out from these openings, and
further reduce the vibration of the golfer's hands to avoid
athletic injury. In the meantime, the present invention has the
effect of lowering the noise. While reducing the vibration, it can
also improve the accuracy of striking the golf ball. The
aforementioned opening further improves the coupling strength by
permeating some of the adhesives into the opening when the club
head and club stick are coupled with adhesives.
[0013] To make it easier for our examiner to understand the
objective of the invention, its structure, innovative features, and
performance, we use a preferred embodiment together with the
attached drawings for the detailed description of the
invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0021] Refer to FIG, 1 for the golf club of the present invention
comprising a club head 1 and a club stick 2; the club head having a
neck section 11 integrally disposed at an upper end of the club
head 1 and an insert hole 12 disposed at an end of the neck section
11; a plurality of openings 13 disposed on the sidewall surrounding
the neck section 11 of the club head 1; such opening 13 could be in
the spiral shape and arranged on the sidewall surrounding the neck
section 11 of the club head 1. Alternatively, the opening 13 could
be in linear shape as shown in FIG. 3, and arranged on the sidewall
surrounding the neck section 11 of the club head 1, or the opening
13 could be in triangular shape as shown in FIG. 4, and arranged on
the sidewall surrounding the neck section 11 of the club head 1, or
the opening 13 could be in circular shape as shown in FIG. 5, and
arranged on the sidewall surrounding the neck section 11 of the
club head 1. The structure with such opening disposed on the
sidewall surrounding the neck section 11 of the club head 1 is
applicable to the wooden club head, iron club head, and putter
head. Since the structure is the same, therefore the wooden club
head is used as an embodiment for illustration in the diagram.
[0022] By means of the opening 13 disposed on the sidewall
surrounding the neck section 11 of the club head 1, the strong
vibration wave produced when striking a golf ball is conducted to
the neck section 11, and some of the vibration waves are dispersed
out from the opening 13, and the remaining vibration waves will be
greatly reduced when they are conducted to the club stick 2. Such
effect is very similar to the fire-extinguishing hood at the front
end of the barrel of a riffle, so that it can reduce the recoil and
vibration. After the vibration is reduced, the stability for the
golfer holding the club will be improved, and further enhances the
accuracy of the direction of the striking ball. Such arrangement
allows beginners to master the golfing technique within a short
time, which is very helpful on building up the confidence of the
player. In addition, the reduction of the vibration can avoid
athletic injury to the hands of the player for the long-time play
of the game.
[0023] Refer to FIG. 6 for the structure of the present invention
having a plurality of openings 13 disposed at the club head 1. When
the club stick 2 coated with adhesive 3 is inserted into the insert
hole 12 of club head 1 also coated with adhesive, some of the
adhesives permeate into the opening 13 to supplement the coupling
interface between the club stick 2 and the club head 1 after the
adhesive in the opening 13 is hardened, so that the coupling
strength of the club stick 2 and the club head 1 is improved, and
they will not fall apart easily.
[0024] While the invention has been described by way of example and
in terms of a preferred embodiment, it is to be understood that the
invention is not limited thereto. To the contrary, it is intended
to cover various modifications and similar arrangements and
procedures, and the scope of the appended claims therefore should
be accorded the broadest interpretation so as to encompass all such
modifications and similar arrangements and procedures.
