Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to a golf club head having a
decorated hosel and a golf club using the golf club head, and
particularly, to a golf club head having a hosel characterized by a
brilliant, three-dimensional decorative member fixed to a surface
of the hosel and a golf club using the golf club head.
[0003] 2. Description of the Related Art
[0004] A portion of a golf club head connected to a shaft is called
a hosel or a neck. A hole for use in connection with the tip end of
a shaft is usually formed inside of a cylindrical shape.
[0005] As mentioned above, the hosel is a portion used for
adhesively fixing a face for use in hitting a ball to the tip end
of the shaft and usually formed from the same material as that of a
head integrally with the head. The appearance of the hosel has
hitherto been provided with no decoration and is devoid of a design
or ornamental characteristic.
[0006] A decorated hosel is disclosed in which calibration marks
are formed in a face surface of the hosel at an arbitrary angle
with respect to the axial direction of a shaft and at intervals
along a circumferential direction of the shaft in order to allow a
golfer to determine the state of an address; and in which the
calibration marks are made in the hosel in the form of a groove;
provided on the hosel in the form of protruding streaks; drawn with
paint; or made by means of coating interior surfaces of grooves
formed in the hosel with paint, as disclosed in Japanese Utility
Model Registration No. 3006951.
[0007] In relation to a ferrule (also called a "socket"), there has
already been proposed a decorated socket in which a decorated ring
is fixed to an appropriate point in the axial cross section of a
socket pipe in order to enhance a decorative characteristic of the
ferrule or the golf club and in which the decorated ring is formed
integrally by means of sandwiching a metallic-colored intermediate
layer, such as metal foil, between a small-diameter tube section
made of a synthetic resin and a large-diameter tube section made of
a synthetic resin, as disclosed in JP-UM-B-55-21710. There has also
been proposed a socket in which metal decoration rings are
interposed among split cylindrical elements of a socket main body
formed so as to become split in an axial direction thereof, as
disclosed in Japanese Utility Model Registration No. 3103748.
SUMMARY OF THE INVENTION
[0008] However, the hosel described in Japanese Utility Model
Registration No. 3006951 is merely machined in consideration of
practical utility; namely, the ease of determination of an address
state, and cannot be said to be decorated. The hosel does not have
any gorgeousness or sumptuousness and is devoid of a design or
ornamental characteristic.
[0009] Likewise, the related-art ferrule and the related-art golf
club described in JP-UM-B-55-21710 and Japanese Utility Model
Registration No. 3103748 are provided with a simple design such as
a chain of ring-shaped patterns. They are devoid of a design or
ornamental characteristic, either; do not show gorgeousness or
sumptuousness; are inconspicuous; and exhibit an indistinctive
design characteristic and yield a low ornamental effect.
[0010] Further, the related-art ferrule is split, and decoration
rings are interposed among the split pieces of the ferrule. Hence,
the related-art ferrule has low strength, and there has been a
drawback of a ferrule of a golf club being easily broken. Moreover,
the ferrule is formed through a plurality of processes and suffers
a drawback of complicated manufacturing processes and an increase
in cost.
[0011] In particular, in association with a recent increase in the
number of female golfers, fashionable golf products, such as wear
or accessories, have been offered, and the golfers enjoy
fashionableness, too. In contrast, a golf club has been developed
to pursue only functionality and lacks an ornamental
characteristic. Hence, the golf club cannot be used with an
ornamental pleasure.
[0012] Therefore, the present invention aims at solving the
drawbacks in the related art and providing a golf club with
decoration without involvement of a decrease in strength, thereby
offering a golf club which exhibits a high ornamental effect; which
can be manufactured readily, inexpensively; which radiates
brilliance, to thus attracts attention; and which enables usage of
the club with an ornamental pleasure, and offering a golf club head
having a hosel for use with the golf club.
[0013] In order to serve as means for solving the drawback,
according to a first aspect of the invention, there is provided a
golf club head including a hosel in which a brilliant
three-dimensional decoration member is fixed to a surface of the
hosel.
[0014] Further, according to a second aspect of the invention
according the first aspect of the invention, a concave portion is
formed on a part of the surface of the hosel; and the brilliant
three-dimensional decoration member is fixed in the concave
portion.
[0015] Further, according to a third aspect of the invention
according the second aspect of the invention, the concave portion
is formed over a circumference of the hosel.
[0016] Further, according to a fourth aspect of the invention
according the second or third aspect of the invention, the concave
portion has a width of from 2 to 5 mm in a shorter side direction
and has a depth of from 0.2 to 2 mm.
[0017] Further, according to a fifth aspect of the invention
according any one of the first to fourth aspect of the invention,
the brilliant three-dimensional decoration member has a width of
from 0.5 to 3 mm.
[0018] Further, according to a sixth aspect of the invention
according any one of the first to fifth aspect of the invention,
the brilliant three-dimensional decoration member includes at least
one of a transparent resinous granular article and a metal granular
article.
[0019] Further, according to a seventh aspect of the invention
according the sixth aspect of the invention, the transparent
resinous granular article is faintly colored.
[0020] Further, according to a eighth aspect of the invention
according the sixth or seventh aspect of the invention, a resin
constituting the transparent resinous granular article is an acryl
resin.
[0021] Further, according to a ninth aspect of the invention, there
is provided a golf club including any one of the golf club head
according to any one of the first to eighth aspect of the
invention.
[0022] According to the present invention described above, a
brilliant three-dimensional decoration member is fixed to a surface
of the hosel. As a result, an ornament can be provided readily,
inexpensively without involvement of a decrease in strength. By
means of radiation of brilliance, a design characteristic and an
ornamental effect can be enhanced, so that a golf club which
noticeably attracts attention and can be used with a pleasure can
be provided.
[0023] Further, an concave portion is formed in a portion of the
surface of the hosel, and the brilliant three-dimensional
decoration member is fixed to the concave portion. Accordingly, the
brilliant three-dimensional decoration member becomes difficult to
exfoliate, and enhanced fixing strength can have been achieved.
Further, an attempt can have been made to reduce the overall weight
of the head. A decrease in the weight of the hosel enables lowering
of the centroid of the head and design of wide-range distribution
of weight become feasible. Enlargement of a sweet area, or the
like, and an increase in the degree of freedom of a design can be
attained.
[0024] Since the concave portion is provided along a circumference
of the hosel, the appearance of the club head is enhanced, and the
design characteristic of the golf club head can be improved.
[0025] Further, a shorter width of the concave portion ranges from
2 mm to 5 mm, and a depth of the concave portion ranges from 0.2 mm
to 2 mm. Accordingly, fixing of the brilliant three-dimensional
decoration member has become easy and reliable.
[0026] The width of the brilliant three-dimensional decoration
member ranges from 0.5 mm to 3 mm. Consequently, the design
characteristic and the ornamental effect can be enhanced without
posing difficulty in playing of a golf.
[0027] Since the brilliant three-dimensional decoration member
corresponds to transparent granular plastic and/or a granular
metallic substance, further enhancement of the design
characteristic can have been achieved by radiation of further
brilliance.
[0028] Since the transparent granular plastic is pale-colored,
further enhancement of the design characteristic can have been
achieved by radiation of further brilliance.
[0029] Since resin of the transparent granular plastic corresponds
to an acrylic resin, the resin becomes less susceptible to
discoloration, so that the resin can radiate greater brilliance
over a long period of time has become feasible.
[0030] Since a golf club includes any one of the ferrules, the golf
club has become possible to yield advantages such as those
mentioned above.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0037] The present invention is described in detail hereunder by
reference to the drawings. In a golf club 10, a grip 3 is attached
to an upper end of a shaft 2, and a lower end of the shaft 2 is
inserted into an insert hole 19 formed in a hosel 41 formed
integrally with a head 4. A ferrule 1 is attached so as to cover
the lower end of the shaft 2 inserted into the hosel 41. There may
also be used the head 4 assembled by fitting the hosel 41 formed
separately from a head main body 49 to the head main body 49. A
concave portion 7 is formed in the surface of the hosel 41, and a
brilliant three-dimensional decoration member 6 is fixed to the
concave portion 7 by way of an adhesive layer 9. The brilliant
three-dimensional decoration member 6 is to form a decoration
element which decorates the hosel 41. The decoration member 6 may
also be used alone, or a plurality of decoration members may also
be used as an ornament having a single pattern such as a floral
pattern, a continual pattern, and the like.
[0038] The hosel 41 is an element for use in adhesively fixing the
tip end of the shaft 2 to a face 45 used for hitting a ball. The
length of the hosel 41 which enables superior adhesion of the shaft
2 preferably ranges from 10 mm to 60 mm. In the case of a golf club
head involving a slow head speed, such as a putter head, the shaft
can be sufficiently fixed even at a length of 10 mm or thereabouts.
However, in the case of a wood golf club head involving a high head
speed, such as an ordinary driver, the length (depth) L of the
insert hole 19 in the hosel 41 ranges from 30 mm to 60 mm. In the
case of an iron golf club head involving an intermediate speed
between the head speed of the putter head and the head speed of the
driver, the length of the insert hole ranges from 20 mm to 35
mm.
[0039] For these reasons, impact force is exerted on a connection
43 between the face 45 and the hosel 41, and hence the thickness of
the connection 43 must be increased to withstand the impact.
Incidentally, the upper end of the hosel 41 requires a length which
enables connection of the shaft 2, but a thickness which is smaller
than the thickness of the connection 43 between the face 45 and the
hosel 41 is sufficient for the upper end in view of strength.
Therefore, the concave portion 7 is desirably provided at a
position which is located inwardly below 3 mm to 20 mm from the
upper end of the hosel 41.
[0040] Granular plastic exhibiting reflectance and brilliance;
especially, transparent granular plastic, a metallic granular
substance, glass, gems, imitation jewelry, and the like, can be
used as the brilliant three-dimensional decoration member 6.
Alternatively, plastic made by coating them with resin or metal, a
chain made by connecting them through use of metal, and the like,
is also available.
[0041] No particular limitations are imposed on resin used for
granular plastic and any granular plastic can be used, so long as
the resin exhibits reflectance and brilliance. Use of resin
exhibiting transparency, more particularly pale-colored resin,
preferably enables radiation of brilliance and enhancement of
design and ornamental characteristics. Alternatively, acrylic
plastic exhibiting high transparency and involving little
discoloration is particularly preferable. Alternatively, common
urethane resin exhibits flexibility and is preferable. However, the
urethane resin becomes yellowed after lapse of a long period of
time. For this reason, use of urethane resin of the type which is
less apt to yellow is desirable.
[0042] Two-pack polyurethane resin is mentioned as urethane resin.
This resin is cold setting resin which involves, at the time of use
of resin, mixing of polyol serving as a base resin with
polyisocyanate serving as a curing agent. Polyol to be used
includes acrylic polyol having a hydroxyl group in molecules,
polyester polyol, polyether polyol, polyurethane polyol, and the
like. Polyisocyanate pre-polymer includes a large number of types
according to isocyanate used as a raw material. Among them,
aromatic isocyanate-based polymers are generally likely to become
yellowed upon exposure to ultraviolet radiation and hence
undesirable. However, xylylene-diisocyanate-based polymers,
isophorone-diisocyanate-based polymers, and
hexamethylene-diisocyanate-based polymers are characterized as
being less apt to yellow.
[0043] Moreover, a metallic granular substance is usually greater
than resin in terms of specific gravity. Hence, it may be the case
where the quantity of metallic granular substance used for fixing
affects the weight of a club head, the balance of a club head, or
the like. Hence, metal having comparatively-small specific gravity;
e.g., aluminum or titanium, is preferably used as the metallic
granular substance.
[0044] Moreover, because of analogous reasons, granular plastics
coated with a metallic film can also be used as a metallic granular
substance. Light metals, such as aluminum, titanium, and the like,
are preferable as a metal film. For instance, an urethane-based
elastomer is coated with aluminum, or acrylic resin is coated with
titanium, thereby imparting metallic gloss to the elastomer and
making the elastomer brilliant.
[0045] Line stone can be used preferably as imitation jewelry. The
line stone is imitation jewelry made of glass and can be formed in
various colors, such as blue, red, green, violet, or the like, by
mixing gold, iron, manganese, or the like with glass.
[0046] In the case of the brilliant three-dimensional decoration
member 6 exhibiting transparency, reflection is enhanced by
affixing metal on the back of the member, whereby the decoration
member preferably becomes more brilliant.
[0047] No specific limitations are imposed on the shape of the
brilliant three-dimensional decoration member 6 within a range
where the decoration member is fitted into the concave portion 7. A
surface of the decoration member opposite an adhesion surface
thereof; namely, a front surface, is provided with a curve such as
a part of a sphere, or a plurality of facets such as facets of
diamond, whereby the appearance of the decoration member can be
made beautiful by utilization of reflection of light.
Alternatively, the back surface of the brilliant three-dimensional
decoration member 6; namely, the surface of the decoration member
opposing the hosel 41, may be plane. However, the surface
preferably assumes a uniform concave surface matching the concave
curve of the opposing hosel 41; namely, a bottom surface 71 of the
concave portion 7. The reason for this is that, by means of such a
configuration, bonding is facilitated, and fixing strength is
enhanced.
[0048] No specific limitations are imposed on the vertical and
horizontal widths of the brilliant three-dimensional decoration
member 6. However, the vertical and horizontal widths of each of
granular substances are preferably set so as to fall within a range
from 0.5 mm to 3 mm. The reason why the widths are made narrow is
that, since the brilliant three-dimensional decoration member 6 is
affixed on a circumference of the cylindrical hosel 41, an adhesive
portion to be affixed cannot fix the decoration member when the
widths are excessively large; particularly, when the back of the
brilliant three-dimensional decoration member 6 is flat, lift
arises in right and left edges of the decoration member, which
readily exfoliate the decoration member. The vertical width and/or
the horizontal width of the brilliant three-dimensional decoration
member 6 may also be made identical with the vertical width of the
concave portion 7, and the brilliant three-dimensional decoration
member 6 may be fitted to the concave portion 7, to thus enhance
fixing strength.
[0049] The concave portion 7 formed in a portion of the surface of
the hosel 41 is provided for making the brilliant three-dimensional
decoration member 6 difficult to exfoliate by means of fixing the
brilliant three-dimensional decoration member 6 to the concave
portion 7, thereby enhancing fixing strength. By means of such a
configuration, removal of the brilliant three-dimensional
decoration member 6, which would otherwise be caused as a result of
being caught; for example, when a golf club is pulled out of a golf
bag or the like, can be prevented.
[0050] Limitations are not particularly imposed on the shape,
number, and position of the concave portion 7. The essential
requirement is to provide the desired number of a concave portion
having a desired shape at a desired location. As shown in FIG. 3A,
the concave portion 7 may be provided on the circumference of the
hosel 41. As shown in FIG. 3B, the concave portion may also be
provided in a portion of the circumference of the hosel 41. As
shown in FIG. 3C, the concave portion may also be vertically
provided over a long area of the hosel 41. As shown in FIG. 3D, the
concave portion may also be provided in a rectangular or circular
shape. A C-shaped cross-sectional profile, or the like, can be
adopted as a longitudinal cross-sectional profile of the concave
portion 7. Moreover, the concave portion can also be configured by
appropriate combination of these shapes. In particular, when such
an concave portion is provided along the circumference of the hosel
41, good appearance is preferably achieved. Alternatively, a bottom
71 of the concave portion 7; namely, a face of the concave portion
7 opposing the brilliant three-dimensional decoration member 6, is
formed so as to assume a linear shape when viewed sideways. This
facilitates affixation of the brilliant three-dimensional
decoration member 6, so that the brilliant three-dimensional
decoration member 6 is stably fixed.
[0051] When the vertical width of the concave portion 7 is too
narrow, the brilliant three-dimensional decoration member 6 becomes
difficult to affix. In contrast, when the vertical width of the
concave portion 7 is too large, a junction between the hosel 41 and
the brilliant three-dimensional decoration member 6 undesirably
becomes likely to catch an external substance. Accordingly, the
vertical width W of the concave portion 7 is preferably set so as
to fall within a range from 2 mm to 5 mm.
[0052] When the thickness N of the concave portion 7 has come to
0.8 mm or less as result of the concave portion having been
recessed deeply, it may be the case where a low thickness portion
undesirably bends when the tip end of the shaft 2 is inserted.
Accordingly, the depth D of the concave portion 7 preferably falls
within a range from 0.2 mm to 2 mm.
[0053] Moreover, the relationship between the depth D of the
concave portion 7 and the height of the brilliant three-dimensional
decoration member 6 is not limited particularly. When the depth D
of the concave portion 7 is greater than the thickness of the
brilliant three-dimensional decoration member 6, difficulty is
encountered in affixing the brilliant three-dimensional decoration
member 6. Conversely, when the depth D of the concave portion 7 is
smaller than the thickness of the brilliant three-dimensional
decoration member 6, the decoration member becomes apt to contact
an external substance and likely to become exfoliated. For these
reasons, as shown in FIG. 4B, a desired depth of the concave
portion 7 is one which allows slight raise of the brilliant
three-dimensional decoration member 6. However, as shown in FIG.
4C, the depth of the concave portion 7 is preferably set to such a
level at which the depth is slightly greater than the thickness of
the brilliant three-dimensional decoration member 6 and at which
the brilliant three-dimensional decoration member 6 becomes fully
buried in the concave portion 7.
[0054] When the golf club head 4 is formed by means of casting and
when the concave portion 7 of the hosel 41 is provided along the
circumference, an internal area of a mold corresponding to the
concave portion 7 becomes narrow, which worsens flow of molten
metal. For this reason, according to a method which provides
superior yields and is desirable because of ease of manufacture, an
area of the mold corresponding to the concave portion 7 is
partially removed such that the upper end of the hosel 41 is
connected to the head main body 49 at an ordinary thickness. The
club head 4 which has been removed from the mold and in which the
concave portion 7 has not yet been formed along the circumference
of the club head is machined through post-processing, thereby
forming the concave portion 7 along the circumference. Moreover,
when the concave portion 7 is cut in a post-processing process,
corners of a protruding area of the mold used for creating the
concave portion 7 are desirably rounded, to thus facilitate flow of
molten metal. When the iron golf club head 4 is created by means of
casting, it may also be better to perform casting in such a way
that an concave portion is previously created in an area of the
hosel 41 where the concave portion 7 is to be created; and to
machine the thus-created concave portion into the concave portion 7
of a desired shape.
[0055] In relation to bonding of the brilliant three-dimensional
decoration member 6 to the hosel 41, there can be used a method for
previously applying an adhesive on the back surface of the
brilliant three-dimensional decoration member 6 and fusing the
adhesive by means of ultrasonic vibration or heating, a method for
welding the brilliant three-dimensional decoration member 6 without
use of an adhesive and by means of ultrasonic vibration or heating
when the brilliant three-dimensional decoration member 6 is made of
resin, or the like, in addition to use of a method for providing an
adhesive layer 9 by means of applying an adhesive to the hosel 41
and press-fitting the brilliant three-dimensional decoration member
6 onto the adhesive layer 9. Moreover, as shown in FIG. 5, a
flexible sheet 8 made of a synthetic resin, or the like, into a
shape fitting the concave portion 7 can be used. The brilliant
three-dimensional decoration member 6 is previously affixed to the
entire surface of the flexible sheet 8 by a method, such as that
mentioned previously, and the adhesive layer 9 is provided on the
other surface of the flexible sheet 8, whereby the flexible sheet 8
is bonded to the hosel 41. In this case, the shape of a floral
pattern, or the like, and a series of pattern, such as a continual
pattern or the like, can have been created in advance by use of the
plurality of brilliant three-dimensional decoration members 6.
Accordingly, manufacture of the decoration member is facilitated
and made easier.
[0056] As shown in FIG. 4A, the brilliant three-dimensional
decoration member 6 may also be fixed directly without forming a
concave portion in the surface of the hosel 41.
[0057] The present invention is practiced in connection with the
iron golf club 10. First, the head is created from SUS630
(stainless steel) by means of the lost wax casting technique. A
metal ingate is positioned on a tow side of the hosel. In order to
make flow of molten metal to the hosel 41 easy, a concave portion
which is to form a portion of the concave portion 7 is created in
an area of the hosel 41 except the tow side and a heel side of the
hosel. The concave portion 7 is machined from a position 5 mm away
from the upper edge of the hosel 41 downwardly to assume a width of
4 mm and a depth of 1 mm. A cutting tool used for boring purpose
and a cutting tool used for scraping are different from each other.
Hence, it is better to create a portion of the concave portion in
advance. The reason for this is that, since machining can be
performed without replacement of the cutting tool, machining is
facilitated.
[0058] The outer diameter of the hosel is formed to 13.5 mm, and
the inner diameter of the hosel is formed to 9.2 mm. The extremity
of the shaft is formed to assume a diameter of 9.0 mm including the
thickness of coating. A paint area on an tip end of the shaft 2
fitted into the hosel 41 is cut away by means of sandpaper. Next,
the ferrule 1 is inserted from the tip end of the shaft 2 to an
appropriate location (separated form the tip end by 28 mm). The tip
end of the shaft 2 is inserted into the insert hole 19 of the hosel
41 and adhesively fixed. The shaft 2 is inserted to a length of 28
mm.
[0059] After full adhesive fixing of the shaft 2 and the head 4, an
adhesive is applied to the concave portion 7, and six granular
substances, which are pale-colored; which are made of clear acrylic
resin and have multi-facets, such as facets of diamond; and which
have vertical and horizontal widths of about 2.5 mm, are affixed to
the concave portion 7 of the hosel 41.
[0060] Consequently, there is acquired a golf club with decoration
without involvement of a decrease in strength, thereby offering a
golf club which exhibits a high ornamental effect; which can be
manufactured readily, inexpensively; which radiates brilliance, to
thus attracts attention; and which enables usage of the club with
an ornamental pleasure.
