Description
FIELD OF THE INVENTION
[0001] The present invention relates to a golf club head
weight-adjusting structure, and more particularly to the design of
a weight-adjusting structure that can be installed to various golf
club heads for adjusting the center of gravity of the head and
maintain its best central position to achieve the effect of
striking a golf ball more accurately.
BACKGROUND OF THE INVENTION
[0002] There are different models of golf club head structures
available in the market, and these golf club heads include driver
heads, putt heads, and iron heads, and a golfer may not be able to
stably control the ball striking direction of a swing, since the
center of gravity of the golf club head is fixed and proximate to a
ball striking surface plate which has a heavy weight based on the
design of the golf club head.
[0003] However, the foregoing golf club head structure still has
the following issues in the actual process of swinging a golf club
to strike a golf ball:
[0004] 1. The center of gravity for a swing is unstable. The
structure of a traditional golf club head comes with a fixed center
of gravity. If the center of gravity for a swing is found unstable,
the balance of the swing will be lowered, and will thus adversely
affect the stable control of striking a golf ball.
[0005] 2. A poor control of striking a golf ball is resulted. Since
the center of gravity of the head is fixed and proximate to the
ball-striking plate, it is difficult to accurately control the ball
striking direction when a strike is made by swinging the golf club
head, and thus it affects the ball striking effect, and the control
of striking a golf ball will not be as good.
SUMMARY OF THE INVENTION
[0006] The primary objective of the present invention is to provide
a golf club head weight-adjusting structure in hope of using this
design to provide a simpler weight-adjusting structure that can
adjust the center of gravity of the head to maintain the best
central position.
[0007] To achieve the foregoing objective of the present invention,
a technical measure adopted by the invention provides a golf club
head weight-adjusting structure, and the weight-adjusting structure
disposed perpendicularly at a rear position of the backside of a
ball-striking plate of various different models of golf club heads
(such as driver heads, putt heads, and iron heads, etc) comprises a
containing body, an adjusting module and a cover panel, wherein the
containing body is extended outwardly from the rear end of the
backside to form a containing groove therein, and both sides of the
containing body have first and second slots, and the containing
body is coupled and perpendicular to a rear end of the backside of
a ball-striking plate of the head. The adjusting module includes a
weight member, a screw rod screwed at the center of the weight
member is pivotally coupled into the first and second slots, and
the screw rod includes rotary elements separately disposed on both
ends of the screw rod; and a cover panel is a member disposed on a
containing portion of a base.
[0008] With the foregoing design of a golf club head
weight-adjusting structure, the present invention can achieve the
following effects:
[0009] 1. A golf ball can be struck more accurately by adopting the
invention. The weight-adjusting structure is perpendicularly
disposed at a rear position of the backside of the ball-striking
plate of different golf club heads, such that the screw rod
disposed at a corresponding position of the adjusting module can be
tuned to adjust the center of gravity of the head to shift
backward, so as to increase the weight of the rear end of the head
and achieve the effect of striking a golf ball more accurately.
[0010] 2. The invention provides a simple structure. The
weight-adjusting structure is comprised of simple components
including a club head body, an adjusting module and a cover panel
for adjusting the center of gravity of the head to shift backward
and maintaining the center of gravity at the best central position,
so as to achieve balanced and stable swings and ball striking
direction and lower the manufacturing cost of the weight-adjusting
structure.
