Abstract
A shock-absorbing golf club head includes a front recess in the striking face of a golf club head, having a plurality of through holes communicating with a rear recess in order to form a shock-absorbing layer when the front recess and the rear recess are formed into shape. A metal face plate affixed to the striking face is mounted in the front recess. When shock-absorbing material is put into the front and rear recesses, a double layer for shock-absorbing is formed, thereby adding shock-absorbing, shock-lessening, and stability to the golf club head to give better ball control.
Description
BACKGROUND OF THE INVENTION
This invention relates to a shock-absorbing golf club head, particularly to one having a double-deck shock-absorbing layer to effectively absorb wrenching and shock force caused by hitting to achieve effective shock-absorbing, shock-lessening, and stability of ball-controlling.
Generally, when a golfer swings a golf club in striking a ball, the striking face of the golf club will give rise to a kind of wrenching and shock force, which may hurt a golfer's wrists.
In order to eliminate such drawbacks, some conventional golf club heads are integrally provided with a shock-absorbing layer for absorbing the wrench and shock force caused by hitting. U.S. Pat. No. 5,772,527 is a typical example.
In accordance with U.S. Pat. No. 5,772,527, the striking face
21
of a golf club head
2
is provided with a recess
22
having projections
23
around a front circumferential edge to be fixedly mounted with a metal face plate
25
by welding, sealing the recess
22
and forming an intermediate hollow with a slot
24
on an upper edge for injecting shock-absorbing material into the recess
22
to form a shock-absorbing layer
1
, as shown in
FIGS. 1
,
2
, and
3
.
However, the wrench and shock force of a golf club head caused by hitting takes place instantly and spreads so quickly that it can hardly be absorbed completely by the single shock-absorbing layer inside the striking face of the golf club head.
SUMMARY OF THE INVENTION
The objective of this invention is to offer a golf club head having a double layer for shock absorbing, able to effectively absorb the wrench and shock force caused by hitting, enabling a golfer to acquire stability of ball controlling.
BRIEF DESCRIPTION OF DRAWINGS
This invention will be better understood by referring to the accompanying drawings, wherein:
FIG. 1
is a perspective view or a known conventional golf club head with a metal faceplate separated:
FIG. 2
is a perspective view of the known conventional golf club head:

is an exploded perspective view of a golf club head with a metal faceplate separated in the present invention:
FIG. 5
is a rear view of the golf club head half completed in the present invention.
FIG. 6
is a front view of the golf club head in the present invention:
FIG. 7
is a rear view of the golf club head in present invention:
FIG. 8
is a vertical side cross-sectional view of the golf club head in the present invention: and
FIG. 9
is a horizontal side cross-sectional view of the golf club head in the present invention.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
A preferred embodiment of a shock-absorbing golf club head in the present invention, as shown in
FIGS. 4 and 5
, includes a front recess
32
in the striking face of a golf club head, extending to the top and the rear portions of the striking face and communicating with a rear recess
33
by means of a plurality of through holes
321
. Then, a shock-absorbing layer
4
is formed into shape and affixed to the front and the rear recesses
32
and
33
, and a metal face plate
34
is fixedly mounted on the front recess
32
, having a dented portion around its circumferential edge fixed with the striking face synchronously when the shock-absorbing layer
4
is formed and affixed to the front and the rear recess
32
and
33
, as shown in
FIGS. 6
,
7
,
8
, and
9
.
In addition, the shock-absorbing layer
4
is formed by compression with shock-absorbing material such as pure rubber or thermoplastic elastomers (so called TPE).
Further,
FIG. 8
shows that the front and the rear recesses
32
,
33
are respectively provided with a shock-absorbing layer
4
formed integrally to make up a double layer for shock-absorbing. With this design, the front shock-absorbing layer
4
in the striking face can directly absorb or lessen the wrench and shock force caused by hitting, and subsequently the rear shock-absorbing layer
4
in the rear recess
33
will completely absorb or eliminate the remaining shock force, thus obtaining an effectiveness of shock-absorbing, shock-lessening and stability of controlling balls.
While the preferred embodiment of the invention has been described above, it will be recognized and understood that various modifications may be made therein and the appended claims are intended to cover all such modifications that may fall within the spirit and scope of the invention.
Claims
- 1. A shock-absorbing golf club head comprising:at least four layers of materials, said layers including a metal face plate, a first shock-absorbing layer, a body of said golf club head, and a second shock-absorbing layer; wherein said body of said golf club head comprises a plurality of through holes, and said first and second shock absorbing layers are formed from a shock-absorbing material, said shock-absorbing material also fills said through holes in said body of said golf club head, an open space on a top side of said golf club head, and an open groove around a perimeter of said metal face plate; such that said shock-absorbing material is exposed on a front side of said golf club head around said perimeter of said metal face plate, said top side of said golf club head, and a rear side of said golf club head, said second shock-absorbing layer covering a majority of said rear side of said golf club head, and said first shock-absorbing layer is in physical contact with said second shock-absorbing layer, thereby maximizing a damping effect.
- 2. The golf-club head as claimed in claim 1, wherein:said shock-absorbing material is a thermoplastic elastomer.
- 3. The golf-club head as claimed in claim 1, wherein:said shock-absorbing material is rubber.
