Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to a golf club head. In
particular, the present invention relates to a golf club head with
at least one damping member.
[0003] 2. Description of Related Art
[0004] U.S. Pat. No. 6,409,612 discloses a weighting member for a
golf club head. The club head comprises at least one indentation or
cavity for receiving at least one weighting device composed of a
polymer body having a plurality of receiving ports therein. A
plurality of high density members are placed within a corresponding
receiving port of the plurality of receiving ports. The plurality
of high density members allow for the weight of the weight device
to be modified depending on the number of the high density members
placed within the receiving ports. The center of gravity of the
golf club head can be adjusted while improving the overall
vibration-absorbing effect of the golf club head.
[0005] The weighting device is mechanically fixed through
compaction in the indentation (or cavity), or chemically adhered to
the recessed portion or indentation with an adhesive. However, in
either case, due to the nature of easy deformation of the
elastomeric weighting device, the weighting device temporarily
deforms during a swing. The bonding reliability between the
weighting device and indentation (or cavity) is adversely affected.
Further, the mechanical or chemical bonding of the weighting device
causes inconvenience to frequent detachment of the weighting device
for altering the number and/or the size of the high density
members. Further, the weight device has a relatively large size and
thus compromises the weighting effect. Further, rolling of the high
density members in the receiving ports result in odd sound during a
swing.
OBJECTS OF THE INVENTION
[0006] An object of the present invention is to provide a golf club
head with improved vibration-absorbing effect while allowing easy
assembly.
[0007] Another object of the present invention is to provide a golf
club head with improved vibration-absorbing effect and reliable
assembly.
[0008] A further object of the present invention is to provide a
golf club head with improved sounding frequency during a swing.
SUMMARY OF THE INVENTION
[0009] In accordance with an aspect of the present invention, a
golf club head comprises a body including at least one compartment
and at least one damping member removably mounted in the at least
one compartment. The damping member includes a receptacle, and a

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0025] Referring to FIGS. 1 and 2, a first embodiment of a golf
club head in accordance with the present invention comprises a body
2 and at least one damping member 3 (one in this embodiment). The
body 2 is made of metal or non-metal material, such as stainless
steel, carbon steel, alloy steel, Fe--Mn--Al alloy, or carbon
fiber. The body 2 can be formed by casting, forging, or mechanical
processing. The body 2 in the illustrated embodiment is a wood-type
golf club head body, detailed structure of which is not described
to avoid redundancy. The body 2 includes at least one compartment
21 (one in this embodiment) in a rear end of a sole thereof. In the
illustrated embodiment, an inner periphery delimiting the
compartment 21 includes an inner threading 22 for threadedly
engaging with the damping member 3.
[0026] The damping member 3 is substantially in the form of a bolt.
The damping member 3 is made of a material the same as or different
from that of the body 2, such as tungsten, iron, nickel, titanium,
copper, and alloys thereof. Usable iron alloys include stainless
steel, carbon steel, alloy steel, and Fe--Mn--Al alloy. The damping
member 3 includes an outer threading 31 for threadedly engaging
with the inner threading 22 of the compartment 21. The damping
member 3 further includes a receptacle 32 defined in an end of the
damping member 3 and a damping block 33 mounted in the receptacle
32. The damping block 33 may be directly filled into and thus
formed in the receptacle 32. Alternatively, the damping block 33 is
formed and then adhered in the receptacle 32. The damping block 33
is made of a damping material capable of absorbing vibrations
generated during a swing. The damping material is selected from the
group comprising epoxy, polyurethane, rubber, thermoplastic
elastomers, foam materials, foamable resins, polyethylene,
polyamides, and mixtures thereof.
[0027] Further, the damping member 3 includes a driving portion 34.
A user may use a tool (such as a wrench or the like, not shown) to
engage with the driving portion 34 for turning the damping member
3, thereby mounting or disengaging the damping member 3 into or
from the compartment 21. The golf club head in FIG. 2 is in an
assembled state. The damping member 3 is reliably mounted in the
compartment 21 of the body 2 due to threaded engagement between the
inner threading 22 of the body 2 and the outer threading 31 of the
damping member 3. During a swing, the damping block 33 in the
receptacle 32 of the damping member 3 absorbs vibrations as a
result of the swing, reducing the odd sounds and improving the
sounding frequency. Loosening of the damping member 3 resulting
from vibrations is less likely to occur.
[0028] It is noted that the center of gravity (CG) of the golf club
head can be adjusted and the moment of inertia (MOI) of the golf
club head can be increased can be can be adjusted by altering the
weight of the damping member 3. The driving portion 34 and the
outer threading 31 of the damping member 3 allows easy, rapid
mounting, removal, and replacement of the damping member 3,
increasing the assembling convenience and improving utility.
[0029] FIG. 3 illustrates a second embodiment of the present
invention. In this embodiment, the body 2 is also a wood-type golf
club head body. Nevertheless, the compartment 21 is defined in a
sole. The compartment 21 in the illustrated embodiment is in the
central portion of the sole. Nevertheless, the compartment 21 can
be in a position adjacent to the toe, heel, or striking plate of
the body 2. Thus, the position of the compartment 21 and the weight
of the damping member 3 can be selected to meet different needs in
the location of the CG and vibration-absorbing effect.
[0030] FIGS. 4 and 5 illustrate a third embodiment of the
invention. In this embodiment, the body 2 is an iron-type golf club
head body comprising a plurality of compartments 21 (three in this
embodiment) in a bottom portion of a rear side thereof, and a
plurality of damping members 3 (three in this embodiment) are
respectively mounted in the compartments 21. Similar to the first
embodiment, an inner periphery delimiting each compartment 21
includes an inner threading 22, and each damping 3 includes an
outer threading 31, a receptacle 32, a damping block 33, and a
driving portion 34. More flexible adjustment in the position of the
CG and the vibration-absorbing effect is allowed.
[0031] FIG. 6 illustrates a fourth embodiment of the invention. In
this embodiment, the damping member 3 includes at least one weight
member 35 (one in this embodiment) mounted in the receptacle 32.
The weight member 35 is at least partially embedded in the damping
block 33. The weight member 35 is made of a material the same as or
different from that of the damping member 3. In this embodiment,
the weight member 35 includes a first end in contact with an end
wall delimiting the receptacle 32 and a second end flush with an
outer end face of the damping block 33. FIG. 7 illustrates a fifth
embodiment of the invention, wherein the weight member (now
designated by 35') is embedded in the damping block 33, with the
first end of the weight member 35' still in contact with the end
wall delimiting the receptacle 32. FIG. 8 illustrates a sixth
embodiment of the invention, wherein the weight member (now
designated by 35'') is completely embedded in the damping block 33,
with the first end of the weight member 35'' not in contact with
the end wall delimiting the receptacle 32. Thus, a variety of
damping members 3 with different vibration-absorbing effects and
different weighting effects (for adjusting the position of the CG)
can be manufactured to allow easy, rapid replacement of the damping
member 3 in the golf club head in accordance with the present
invention, increasing the assembling convenience and improving
utility.
[0032] FIG. 9 illustrates a seventh embodiment of the invention
modified from the fourth embodiment in FIG. 6. In this embodiment,
an inner periphery delimiting the receptacle 32 includes an inner
threading 321, and the damping block 33 includes an outer threading
331 for threading engagement with the inner threading 321 of the
receptacle 32. Further, a driving portion 351 is provided on an end
of the damping block 33, allowing easy, rapid removal of the
damping block 33 by a wrench or the like. Thus, the damping member
3 can be used with various damping blocks 33 and various weight
members 35, reducing the number of the damping blocks 3 while
increasing assembling convenience and improving utility.
[0033] While the principles of this invention have been disclosed
in connection with specific embodiments, it should be understood by
those skilled in the art that these descriptions are not intended
to limit the scope of the invention, and that any modification and
variation without departing the spirit of the invention is intended
to be covered by the scope of this invention defined only by the
appended claims.
