Description
CROSS-REFERENCE TO RELATED APPLICATION
[0001] This application claims the priority benefits of U.S.
provisional application Ser. No. 60/749,178, filed on Dec. 19,
2005. All disclosures are incorporated herewith by reference.
BACKGROUND OF THE INVENTION
[0002] 1. Field of the Invention
[0003] The present invention generally relates to a machine tool
and a fabricating method of a golf club head. More particularly,
the present invention relates to a surface finishing tool and a
method for forming a pattern on a golf club head.
[0004] 2. Description of Related Art
[0005] Sports are becoming more and more popular, and golf has
already become one of the most widely enjoyed sports. In addition,
the number of participants in the sport of golf has risen rapidly.
In which, the golf club used for playing golf, because of the
varieties in purposes and course geographies, are categorized into
different types such as wood club, iron club, and putter. However,
an appearance design is also important for the success of the
products, wherein surface finishing is usually conducted to form
various patterns for aesthetic appeal on the surface of the golf
club head.
[0006] Conventionally, such patterns always appear on the planar
external surface of the golf club head such as the striking surface
of a putter as shown in FIG. 1, wherein planar milling performed by
a numerical control (NC) machine is applied on the striking surface
of the putter to form the patterns. However, the conventional
fabricating method for forming the patterns on the golf club head
still has at least the following limitation and drawbacks. Firstly,
the planar milling can be only applied on a planer surface, and
thus the positions of the conventional patterns are limited on
specific regions of the golf club, e.g. the striking surface of the
putter. Secondly, application of the planar milling is restricted
by the lifetime and the reliability of the machine tool, wherein
high hardness or toughness material are excluded from being
fabricated. Furthermore, the fabricating process of the planar
milling performed by the NC machine is complex and takes a long
time, which leads to a high production cost.
SUMMARY OF THE INVENTION
[0007] Accordingly, the purpose of the present invention is to
provide a widely used surface finishing tool for forming patterns
on any preferred region of the golf club in addition to the planar
surface.
[0008] The purpose of the present invention is to provide a
fabricating method having simple process and lower cost by using
the surface finishing tool mentioned above.
[0009] The purpose of the present invention is to provide a golf
club fabricated by the aforementioned method and surface finishing
tool.
[0010] Based on the aforementioned and other purposes, the present
invention proposes a surface finishing tool for forming a pattern
on a golf club head. The surface finishing tool comprises a shank,
a resilient cylinder, and a rubbing head. The shank has a center
axis, and the resilient cylinder is disposed along the center axis
and fixed on an end of the shank. In addition, the rubbing head has
a rough surface and is disposed on the resilient cylinder.
[0011] In an embodiment of the present invention, the resilient
cylinder is made of rubber.
[0012] In an embodiment of the present invention, the rubbing head
comprises abrasive cloth.
[0013] The present invention also proposes a fabricating method for
forming a pattern on a golf club head by using the aforementioned
surface finishing tool. In the fabricating method, the surface
finishing tool is driven to rotate along the center axis first.
Then, the surface finishing tool is moved for keeping the rough
surface of the rubbing head contacting with the golf club head to
form the pattern on the golf club head, wherein the resilient
cylinder is deformed along a profile of the golf club head as the
rubbing head contacts with the golf club head.
[0014] In an embodiment of the present invention, the surface
finishing tool is driven by a rotary machine, which may be a
driller, a lathe, or a miller.
[0015] The present invention further proposes a golf club head
having the pattern made by the fabricating method mentioned
above.
[0016] In an embodiment of the present invention, the pattern
formed on the golf club head is a whirlpool pattern.
[0017] With the elasticity of the resilient cylinder, it is assured
that the rough surface of the rubbing head is kept contacting with
the golf club head during the fabricating process, and thus the
pattern can be formed on any preferred regions of the golf club
head, even the one having curved surface.

serve to explain the principles of the invention.
[0019] FIG. 1 shows a conventional striking surface of a putter
having a pattern.
[0020] FIG. 2 schematically shows a surface finishing tool
according to an embodiment of the present invention.
[0021] FIG. 3 schematically shows the fabricating method according

[0022] FIGS. 4-7 show different golf club heads having patterns
according to embodiments of the present invention.
DESCRIPTION OF THE EMBODIMENTS
[0023] Reference will now be made in detail to the present
preferred embodiments of the invention, examples of which are
illustrated in the accompanying drawings. Wherever possible, the
same reference numbers are used in the drawings and the description
to refer to the same or like parts.
[0024] The present invention mainly provides a surface finishing
tool and a fabricating method applying the same for forming a
pattern on a golf club head. By the surface finishing tool and the
fabricating method, the pattern can be easily formed even on a
curved surface of the golf club head in a simpler and low-cost way.
The surface finishing tool and the accompanying fabricating method
will now be illustrated in more detailed by embodiments in the
following paragraphs, wherein a work piece for being fabricated in
the embodiments can be various portion of the golf club head, such
as crown, sole, striking surface, or back surface.
[0025] FIG. 2 schematically shows a surface finishing tool
according to an embodiment of the present invention. As shown in
FIG. 2, the surface finishing tool 300 comprises a shank 310, a
resilient cylinder 320 and a rubbing head 330. The shank 310 has a
center axis 310a, and the resilient cylinder 320 is disposed along
the center axis 310a and fixed on an end of the shank 310. The
rubbing head 330 has a rough surface 330a and is disposed on the
resilient cylinder 320.
[0026] In the present invention, the shank 310 can be mounted on a
rotary machine (not shown) and driven by the same for rotating
along the center axis 310a. Moreover, the resilient cylinder 320 is
made of rubber or other applicable elastic materials, which is
suitable for being deformed along a profile of a workpiece in the
fabricating process. The rubbing head 330 may comprise abrasive
cloth and rub against the workpiece through the rough surface 330a
to form the pattern thereon.
[0027] FIG. 3 schematically shows the fabricating method according
to an embodiment of the present invention. As shown in FIGS. 3, the
fabricating method is suitable for forming a pattern on a finished
surface 400a of a workpiece 400 by using the aforementioned surface
finishing tool 300: First, the surface finishing tool 300 is driven
to rotate along the center axis 31Oa. In order to drive the surface
finishing tool 300, the shank 310 of the surface finishing tool 300
may be mounted on a rotary machine (not shown), such as a driller,
a lathe, or a miller.
[0028] Then, the surface finishing tool 300 is moved to contact
with the finished surface 400a of the workpiece 400 and makes the
rubbing head 330 rub against the finished surface 400a of the
workpiece 400 through the rough surface 330a. Since the resilient
cylinder 320 is elastic and can be deformed along the profile of
the workpiece 400, the rough surface 330a of the rubbing head 330
can be kept contacting with the finished surface 400a of the
workpiece 400 even if the surface is a curved surface and thus
forms the pattern on the finished surface 400a of the workpiece
400.
[0029] Specifically, the dimensions and resolution of the pattern
depend on the size of the resilient cylinder 320 and the roughness
of the rough surface 330a, e.g. the mesh of abrasive cloth. In one
case, the pattern can be a whirlpool pattern if the surface
finishing tool 300 is kept rotating and staying at one point on the
workpiece 400. However, the surface finishing tool 300 can further
be driven in different dynamic modes and then forms various
patterns on the workpiece 400. For example, a striped pattern can
be attained by driven the surface finishing tool 300 to move along
a path, and a stacked whirlpool pattern can be formed by repeating
the fabricating process.
[0030] In a practical application, the fabricating method can be
applied to a surface color paint of a golf club head to form a
novel and brilliant pattern thereon. By the effect of various
reflecting light from the brilliant pattern, the aesthetic appeal
of the golf club head can be improved. FIG. 4 shows an iron club
head, wherein several whirlpool patterns are formed on a striking
surface thereof. FIG. 5 shows another iron club head having
whirlpool patterns on its back surface. In addition, FIG. 6 shows a
crown of a. wood club head, wherein multiple whirlpool patterns are
formed on the surface color paint and covered by varnish. Moreover,
FIG. 7 shows another wood club head, wherein whirlpool patterns are
formed on a sole of the wood club head.
[0031] Accordingly, the present invention provides a useful surface
finishing tool for forming patterns on any preferred regions of the
golf club head, for.example on a planar surface or a curved
surface. By using the surface finishing tool, a fabricating method
having simple process and lower cost is also provided. Therefore,
the production yield and the aesthetic appeal can be improved and
the success in the market is expected.
[0032] It will be apparent to those skilled in the art that various
modifications and variations can be made to the structure of the
present invention without departing from the scope or spirit of the
invention. In view of the foregoing, it is intended that the
present invention cover modifications and variations of this
invention provided they fall within the scope of the following
claims and their equivalents.
