ABSTRACT:
BACKGROUND OF THE INVENTION
A complacent golf putter is something to a golfer just like a good brush is to a painter. The common point is that both require delicate skills, which can be accumulated and upgraded only by constant practice.
As the green is where the golfers fight it out, in addition to skill and experience, a complacent putter is also considered a key weapon for winning a game. However, as the center of gravity of an existing golf putter is usually unadjustable and located at its center position, a slight striking deflection will cause a miss of the so-called “sweet spot” effectively.
Various patented structures of golf putter are briefly described with annexed diagrams as below:
1. According to the disclosed patent No. 83208275 in Taiwan dated Mar. 1, 1996 (shown in FIG.
1
), a putter head
1
is combined with a neck
10
, wherein the putter head
1
is provided with a plurality of tapped holes
11
selectable for fixedly jointing the putter head
1
to the neck
10
and a golf shaft
12
, and for compensating offset of a center of gravity A (shown in FIG.
2
). However, in the small enclave of the putter head
1
, only a few tapped holes
11
can be made available for adjusting the center of gravity A. It can hardly meet different requirements of the users.
2. According to another disclosed patent No. 83216776 in Taiwan dated Jul. 1, 1996 (shown in FIG.
3
), a putter head
2
and a neck
20
are screw-jointed, then a shaft
21
is inserted in the neck
20
to form a golf club. In this structure, the center of gravity A is fixed because there is only one screw-joint position available in spite of the rotatable neck
20
.
3. According to a further disclosed patent No. 80210365 in Taiwan dated Apr. 21, 1997 (shown in FIG.
5
), a neck
30
is inserted in a putter head
3
then jointed with a shaft
31
, wherein the neck
30
is curved in a designated angle with a specified weight, hence, the center of gravity is deflected upwards from the ball center (shown in
FIG. 6
) to affect striking accuracy.
In view of the above-described imperfections, after years of constant effort in research, the inventor of this invention has consequently developed and proposed an improved framework pertaining to the subject matter.
SUMMARY OF THE INVENTION
This invention relates to a four-in-one golf putter comprising a body, two wing parts, and an insertion piece, made of a material respectively with specific gravity different from each other, which may be associated in different combinations and adjusted to create center of gravity in different positions. For more detailed information regarding this invention together with further advantages or features thereof, at least an example of a preferred embodiment will be elucidated below with reference to the annexed drawings.
