Description
CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] This non-provisional application claims priority under 35
U.S.C. .sctn.119(a) on Patent Application No(s). 094222985 filed in
Taiwan, R.O.C. on Dec. 29, 2006, the entire contents of which are
hereby incorporated by reference.
BACKGROUND OF THE INVENTION
[0002] 1. Field of Invention
[0003] The present invention relates to a golf club head, and more
particularly, to a golf club head for providing an optimal
vibration damping effect and having a structure of fixing weighted
parties.
[0004] 2. Related Art
[0005] In order to enable golf club heads to achieve the most
preferred striking effect, weighted structures are generally
disposed at the bottom of the club head to make the gravity center
of the club head move downwards, which increases the striker's
stability in swinging, helps the striker to effectively strike the
ball, so as to increase the flying distance of the ball and make
the ball fall at a predetermined position. Therefore, the design of
the weighted structure for the club is an extremely important
factor for determining the quality of the golf club and the
striking score of the striker.
[0006] Recently, the commonly used club head has an arc-shaped club
head body fixed with the club holder, and the club head body is
hollow and has a striking face at the front end portion, which is a
ramp. There are two types of weighted structures: the first one is
that a weighted block made of a material heavier than that of the
club head body is fastened on the back end of the club head body;
and the other one is that the weighted block is inlaid on the
bottom surface of the club head body.
[0007] Furthermore, as for the above weighted structure of the club
head, the weighted block is fastened on the back end or on the
bottom surface of the club head from the exterior, and only the
weighted block made of a single material is used. The vibration
damping capability of the weighted block made of a single material
is not desired, and it is also impossible to provide sufficient
vibration damping effect to absorb the vibration generated when
striking the ball. On the other hand, the fastening manner
generally includes screw locking, adhering, or welding. When
striking, the club is affected by the counteracting force, and
vibration occurs for the club head body, and due to the different
materials used by the weighted block and the club head body, their
conductivities for the vibration wave are different, and thus, when
the vibration wave passes between the weighted block and the club
head body, a shearing force is generated on the joining part
there-between. Therefore, after the club has been used for a long
time, the weighted block is easily loosen and fallen off from the
club head body, so that the club is damaged, and the service life
of the club is reduced.
[0008] Therefore, the conventional weighted structure of the golf
club head is directly fastened on the back end or lightly inlaid on
the bottom of the club head body, which has the disadvantage that
the weighted effect for the club head is limited, so the gravity
center cannot be effectively moved downwards, and meanwhile, the
optimal striking position is limited in a relatively small scope.
Therefore, it is an important issue for research and development in
this field to redesign a golf club head having a structure of
fixing weight body and a two-stacked weighted part structure, for
providing preferred vibration damping function for the user.
SUMMARY OF THE INVENTION
[0009] In view of the above problems of the conventional art, the
present invention provides a golf club head with dual weighted
parties having fixing structure, for solving the problems of the
weighted structure in the conventional golf club head that the
weighted effect is limited, and the vibration damping effect cannot
be enhanced.
[0010] In order to achieve the above object, the present invention
provides a golf club head with dual weighted parties having fixing
structure, which comprises a body, a first weighted part having a
fastening portion, and a second weighted part having a fixing
portion on each end and a joining portion at the bottom part. The
body has a cavity for fastening the first weighted part therein and
a snapping portion at the bottom of one side surface. The second
weighted part uses the fixing portion and the joining portion to
respectively snap with the snapping portion of the body and embed
in the fastening portion of the first weighted part, such that the
first weighted part and the second weighted part are fixed in the
body, and thereby finishing the fabricating of the golf club head
with dual weighted parties having fixing structure of the present
invention.
[0011] By implementing the present invention, at least the
following functions are achieved.
[0012] First, the present invention relates to a golf club head
with dual weighted parties having fixing structure, and by
implementing the golf club head with dual weighted parties having
fixing structure, the weighted structure made of a variety of
materials is provided, thereby improving the vibration damping
function.
[0013] Second, the present invention relates to a golf club head
with dual weighted parties having fixing structure, and by
implementing the golf club head with dual weighted parties having
fixing structure, a specific style of logo or a specific company
trademark is positioned between the dual weighted parties, for
distinctly enhancing the quality of the golf club head, and
providing a unique diversity, which also has an anti-copying
effect.
[0014] Third, the present invention relates to a golf club head
with dual weighted parties having fixing structure, and by
implementing the golf club head with dual weighted parties having
fixing structure, an upper weighted part with a different
appearance and color can be fabricated to cater to customers'
requirements, so as to provide a variety of selections for the
