Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to a grip of golf club and its
manufacture method, and more particularly to a grip of golf club
with a damping effective expanded sandwiching and an anti-slip
surface constituted of rubber collars and rubber-fibre composite
spacing arrange, and the manufacture processing.
[0003] 2. Description of Prior Art
[0004] In accordance with the conventional grip of golf club, most
of them are moulded of single material-rubber expected to buffer
the strike on the hands as batting. But the damping effect is not
so good as expectation actually. On the other hand, for increasing
the friction between the grip and the hands so as to reduce the
rate of slipping out from the hands, some manufacturers cover a
fibre mesh on the outside surface of the semi-finished articles to
process together so that the finished product appears many cross
strands of fibre on the surface of the rubber grip (as shown on
FIG. 9). Even though the rubber grip is covered with the fibre, the
users still feel it will slip out easily.
OBJECTS AND SUMMARY OF THE INVENTION
[0005] It is therefore a main object of the present invention to
provide a grip of golf club, which has a better damping effect as
batting and more smoothly with a great friction.
[0006] This object is achieved by a grip of golf club, which is
consisted of a core bar, an expanded sandwiching, and a surround.
Wherein, the core bar has a collar indentation for retaining the
expanded sandwiching and the surround sequentially from inner to
outer; the surround is an anti-slip cover in which the rubber
collars are covered on the hoop rubber and rubber-fibre composite's
surfaces in spacing arrange axially.
[0007] For obtaining above-mentioned structure and functions, the
manufacture process provided in the present invention includes the
following processing steps: pre-mould the core bar with the collar
indentation, and fill out the foaming material in the collar
indentation; then cut out the raw rubber sheet suiting to cover on
the outside of the foaming material, and layover the fibre mesh on
the raw rubber sheet, next stick the rubber collars on the outside
of the fibre mesh layer in spacing arrange axially to combine the
surround; then gum the combined surround layer up on the core bar
collar indentation portion filled with foaming material be a
semi-finished article for standing by. Finally process the
semi-finished grip in the mould with heating setting and
sulphurating treatment to shape a finished product.
[0008] In processing, for avoiding the foaming material overflowing
from the seaming of the surround, before gumming the surround up on
the foaming material, pre-lay a thin raw rubber type along the
seaming portion to screen the under foaming material inside. Or
laps joint the both side edges of the surround to get the same
effect.
[0009] For avoiding the foaming material overflowing from the both
joint ends between the rims of the collar indentation and the
surround, before gumming the surround up on the foaming material,
pre-lay a raw rubber type on inside of the joint portion for
screening the joint separately.
[0010] Due to applying said expanded interlayer, the reactive force
of the strike is absorbed to get the damping effect. The grip is
moulded in the mould with heating treat so that the attached layers
integrate into the core bar. In addition, because the rubber
collars are arranged in spacing arrange axially on the surfaces of
the hoop rubber and the rubber-fibre composite of the grip to form
two different friction coefficients in checker arrange axially, so
that the hands grasp at the grip more smoothly.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
[0020] Referring to FIG. 1, it shows the outlook of the present
invention, which is covered with rubber 11 and the rubber-fibre
composite 12.
[0021] Referring to FIG. 2 to FIG. 8, the present invention
consists of a core bar 2, an expanded sandwiching 3, a surround 4.
Wherein, the core bar 2 has a collar indentation 21 for retaining
the expanded sandwiching 3 and the surround 4 sequentially from
inner to outer; said surround is an anti-slip cover in which the
rubber collars are covered on the hoop rubber 11 and rubber-fibre
composite 12's surface in spacing arrange axially.
[0022] The above-mentioned grip of golf club may be manufactured as
following processing steps:
[0023] Referring to FIG. 2, firstly, pre-mould the core bar 2 with
the collar indentation 21, and fill out the foaming material 3' in
the collar indentation 21 for ready (referring to FIG. 3); then
referring to FIG. 4, cut out the raw rubber sheet suiting to cover
on the outside of the foaming material, and layover the fibre mesh
41 on the raw rubber sheet, next stick the rubber collars 42 on the
outside of the fibre mesh layer in spacing arrange axially to
combine the surround 4; then gum the combined surround layer 4 up
on the core bar collar indentation 21 portion filled with foaming
material 3' for standing by. Finally (referring to FIG. 6) process
the semi-finished grip in the mould with heating setting and
sulphurating treatment so that the foaming material fills out the
space between the collar indentation and the inside of the surround
4 to form a damping interlayer. Meanwhile the surround 4 in the
heating setting processing is pressed from the both sides, one is
come from inside foaming interlayer, and the another is limited by
the die, so that the foaming interlayer and the surround 4 are made
in thermal interfusion together to form an integrated grip with an
anti-slip surface mechanism--the rubber collars 11 and the
rubber-fibre composite 12 in spacing arrange.
[0024] Referring to FIG. 7, in processing, for avoiding the foaming
material 3' overflowing from the seaming of the surround 4 so as to
damage the outward appearance, so before gumming the surround 4 up
on the foaming material 3', pre-lay a thin raw rubber type 7 along
the seaming portion 43 to screen the seaming line of the surround
4. Or lap joints the both side edges of the surround 4 to get the
same effect (unshown in the drawing). As heating process in the
mould, the raw rubber type 7 will be interfused with the surround 4
so as to seal the joint of the surround 4 to block the overflowing
channel.
[0025] Referring to FIG. 8, for avoiding the foaming material 3'
overflowing from the both joint ends between the rims 22 and joints
23 of the collar indentation 21 and the surround 4 to damage the
outward appearance, before gumming the surround 4 up on the foaming
material 3', pre-lay a raw rubber type 7 on inside of the joint
portion (in the drawing, a raw rubber ring 7 is placed on the
inside end in another operation of the present invention) for
screening the joint separately. As heating process in the mould,
the pre-laid raw rubber type 7 will be interfused with the surround
4 and the rim 22 of the collar indentation 21 so as to seal the
joint portions to block the overflowing channel.
