Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to a golf club head. More
particularly, the present invention relates to a golf club head,
which utilizes a flange and a groove to be squeezed with each other
and to be deformed so as to form a close engagement relation.
[0003] 2. Description of the Prior Art
[0004] Generally, in a golf club head, a body and a striking face
plate are mostly combined through a titanium-pressing technique. At
least one flange and at least one groove are correspondingly
disposed on corresponding end surfaces of the body and the striking
face plate respectively, and the flange and the groove are squeezed
with each other to generate a deformation function, so as to
closely match the club head with the striking face plate into a
whole. However, in this method, if the shape and the position of
the flange and the groove are poorly designed, both the flange and
the striking face plate are easily deformed during squeezing, and
as a result, the striking surface is restricted to a plane, which
makes the light-weighting or weighting effect limited, and makes
the elastic effect poor, and thus, the effective striking area is
relatively small. Therefore, people skilled in the art combine the
club head body with the striking face plate through a
lateral-fastening structure.
[0005] FIG. 1 is a schematic view of a structure with the club head
body and the striking face plate being combined through a
lateral-fastening structure. The conventional golf club head
includes a striking face plate 110 and a club head body 120. The
striking face plate 110 is cup shaped, and at least one catching
flange 111 is disposed near an inner side at an opening. A catching
portion is disposed on an end surface of the club head body 120
facing the striking face plate 110, and at least one annular slot
121 is opened at a position of the catching portion corresponding
to the catching flange 111. Then, after the catching flange 111 and
the annular slot 121 are aligned with each other, the striking face
plate 110 is pressed under an external force in order to engage the
catching flange 111 with the annular slot 121, so that the striking
face plate 110 is combined with the club head body 120 to form a
club head through the lateral-fastening structure.
[0006] However, the above manner has inevitable disadvantages, that
is, if shapes of the catching flange and the annular slot are
poorly designed, if the design of the corresponding position is
inaccurate, if the force is not uniformly applied on the striking
face plate, or if the stress resistance of the fabrication material
itself is relatively high, then the striking face plate and the
club head body cannot be easily engaged together closely. A slit
may be generated at the joint surface, so that the combined
strength of the striking face plate and the club head body is quite
limited. Furthermore, due to the external force, the striking face
plate may fall off the club head body.
SUMMARY OF THE INVENTION
[0007] In order to solve the above problems, the present invention
provides a golf club head, which is capable of easily, quickly and
accurately combining the striking face plate and the body closely
into a whole, effectively controlling the effective striking area
of the striking face plate, easily performing the light-weighting
or weighting block operating flow, and preventing a joint slit from
generating at the joint surface between the striking face plate and
the body, so as to improve the combined strength of the striking
face plate and the body.
[0008] The present invention provides a golf club head. The golf
club head includes a face plate and a body. The face plate has an
annular fastening portion with at least one fastening groove
mounted therearound. The body has a clamping portion including at
least one annular block and at least one annular stopper. An
accommodation slot is formed between the annular block and the
annular stopper, and is used for accommodating the annular
fastening portion. At least one flange is disposed on the top of
the clamping portion. During the assembling process, the annular
fastening portion corresponds to the accommodation slot, and the
face plate is pressed under an external force and squeezed towards
the body. At this time, the flange bears against the face plate,
and the flange is pressed so that it is deformed towards the
direction of the fastening groove, so as to form a catching portion
for being engaged with the fastening groove. The annular block
bears against the annular fastening portion, so as to help the
annular fastening portion to be accurately accommodated into the
accommodation slot and closely adhered to the accommodation
slot.
[0009] In addition, when the flange is disposed on an end surface
of the annular stopper facing the face plate, if the position of
the annular stopper corresponds to an inner side of the annular
fastening portion, the fastening groove is disposed on the inner
side of the annular fastening portion corresponding to the position
of the flange, and the annular block is disposed correspondingly on
an outer side of the annular fastening portion. However, if the
position of the annular stopper corresponds to the outer side of
the annular fastening portion, the fastening groove is disposed on
the outer side of the annular fastening portion corresponding to
the position of the flange, and the annular block is disposed on
the inner side of the annular fastening portion. Next, if the
flanges are disposed on the end surfaces of both the annular block
and the annular stopper facing the face plate, the fastening
grooves are disposed on both the inner side and the outer side of
the annular fastening portion. Furthermore, the cross section of
the fastening groove is a trapezoid and with the opening facing the
annular stopper, and the flange is disposed on the end surface of
the annular stopper facing the face plate. Furthermore, the flange
can be disposed around the clamping portion in a continuous manner
or an equidistant or non-equidistant interrupted manner, and the
fastening groove, corresponding to the flange, is mounted around
the annular fastening portion in a continuous manner or an
equidistant or non-equidistant interrupted manner. In addition, the
fastening groove is a groove with a rectangle-shaped, arc-shaped,
straight V-shaped, or trapezoid-shaped cross section, and the club
head is one of an iron club head, a wood club head, or a putter
head.
[0010] The following efficacies are achieved by the present
invention. The striking surface can be randomly designed, and can
extend to the outer side of the body to increase the effective
striking area. Next, the striking face plate can be light-weighted
by using a titanium alloy, which is helpful for the weighting
process. Furthermore, it merely requires the processes of joining
the striking face plate and the body, pressing the flange into the
fastening groove, and performing a layout flattening operation, so
the yield is is improved without any complex operating flow.
Furthermore, the face plate and the body are closely joined
together through making the annular block bear against the annular
fastening portion, thereby preventing the joint slit from
generating on the joint surface.

DETAILED DESCRIPTION OF THE INVENTION
[0037] To make the objective, structural features, and function of
the present invention more comprehensible, the relevant embodiments
and detailed description of the drawings are described as
follows.
[0038] FIGS. 2A to 2C are a schematic structural view, a schematic
structural view at the pressing process, and a combined schematic
structural view of a golf club head according to a first embodiment
of the present invention respectively, which show the process of
combining a face plate 210 with a body 220. The face plate 210 has
an annular fastening portion 211, and a fastening groove 212. The
fastening groove 212 with a rectangle-shaped cross section is
mounted around an inner side of the annular fastening portion 211.
The body 220 has a clamping portion 221 formed by an annular block
222 and an annular stopper 223. An accommodation slot 225 is formed
between the annular block 222 and the annular stopper 223. An
opening of the accommodation slot 225 corresponds to the annular
fastening portion 211, and the annular stopper 223 comprises a
flange 224 disposed on an end surface of the annular stopper 223
facing the face plate 210.
[0039] The annular fastening portion 211 and the accommodation slot
225 are made to align with each other, and the face plate 210 is
pressed under an external force and squeezed towards the body 220.
The annular fastening portion 211 is accurately placed into the
accommodation slot 225. In this embodiment, the position of the
annular block 222 corresponds to the outer side of the annular
fastening portion 211, and the position of the annular stopper 223
corresponds to the inner side of the annular fastening portion 211.
The flange 224 bears against the face plate 210, and the face plate
210 and the body 220 are continuously squeezed with each other in
order to be gradually deformed towards the direction of the
fastening groove 21, so as to form a catching portion 227 for being
engaged with the fastening groove 212. However, the annular block
222 bears against the outer side of the annular fastening portion
211, which aims at preventing the annular fastening portion 211
from being deformed due to an excessively strong force generated
when the face plate 210 and the body 220 are squeezed with each
other. Therefore, the annular fastening portion 211 can be closely
adhered to the inner side of the accommodation slot 225, so as to
prevent slits from being generated at the joint surface between the
face plate 210 and the body 220. Furthermore, if slight bumps or
metal burrs are generated at the outer side part of the joint
surface between the face plate and the body due to the mutual
squeezing process therebetween, a polishing process or other
similar surface processing operations can be used for
finishing.
[0040] FIGS. 3A and 3B are a schematic structural view and a
combined schematic structural view of a golf club head according to
a second embodiment of the present invention respectively. In order
to assure that the flange is deformed towards the direction of the
fastening groove during squeezing, the flange is designed with a
configuration having a lead angle, as shown by the trapezoid flange
226. When the face plate 210 and the body 220 are squeezed with
each other, the trapezoid flange 226 firstly bears against the face
plate 210 and is pressed by the squeezing force, and an inclined
surface of the trapezoid flange 226 is relatively slowly pressed by
the squeezing force, so the trapezoid flange 226 can only be
deformed towards the fastening groove 212 to form a catching
portion 227 for being engaged with the fastening groove 212.
[0041] FIGS. 4A and 4B are a schematic structural view and a
combined schematic structural view of a golf club head according to
a third embodiment of the present invention respectively. The
fastening groove can be designed as a trapezoid-shaped fastening
groove 213 with a trapezoid-shaped cross section, so that the
trapezoid flange 226 can form a hook-shaped catching portion 227
once it is squeezed and deformed, thereby enhancing the engagement
effect between the face plate 210 and the body 220. In addition,
the fastening groove can be designed as grooves in different
shapes, for example, with an inclined V-shaped, arc-shaped, or
straight V-shaped cross section, depending upon different
situations. Furthermore, the flange can be disposed around the
clamping portion in a continuous manner or an equidistant or
non-equidistant interrupted manner, and the fastening groove,
corresponding to the flange, is mounted around the annular
fastening portion in a continuous manner or an equidistant or
non-equidistant interrupted manner.
[0042] FIGS. 5A and 5B are a schematic structural view and a
combined schematic structural view of a fourth embodiment of the
present invention respectively. In this embodiment, the position of
the annular stopper 223 corresponds to the outer side of the
annular fastening portion 211, and the position of the annular
block 222 corresponds to the inner side of the annular fastening
portion 211, so the fastening groove 212 is opened on the outer
side of the annular fastening portion 211. The trapezoid flange 226
is disposed on the end surface of the annular stopper 223 facing
the face plate 210. During the assembling process, the
trapezoid-shaped flange 226 bears against the face plate 210 and is
deformed towards the direction of the fastening groove 212, so as
to form the catching portion 227 for being engaged with the
fastening groove 212. At this time, the annular stopper 223 may
generate slight bumps or metal burrs due to the squeezing process,
and a polishing process or other similar surface processing
operations can also be used for finishing. The annular fastening
portion 211 bears against the annular block 222 to prevent the
slits from being generated at the joint surface.
[0043] FIGS. 6A and 6B are a schematic structural view and a
combined schematic structural view of a golf club head according to
a fifth embodiment of the present invention respectively. The
fastening grooves 212 are disposed on both the inner side and the
outer side of the annular fastening portion 211 on the face plate
210. The flanges 224 are disposed on both the end surfaces of the
annular block 222 and the annular stopper 223 facing the face plate
210. Therefore, when the face plate 210 and the body 220 are
assembled, the flanges 224 are turned to become the catching
portion 227 for being engaged with the fastening groove 212. In
this embodiment, the combined strength of the face plate 210 and
the body 220 is increased through the multi-engaging effects of the
catching portion 227 and the fastening groove 212.
[0044] FIGS. 7A to 7D are a schematic structural view and a
schematic flow chart of a sixth embodiment of the present invention
respectively. The face plate 210 has a butting fastening portion
230 having a butting fastening groove 231 with a trapezoid-shaped
cross section. The opening of the butting fastening groove 231 is
relatively small, and the opening faces the body 220. The body 220
has a butting clamping portion 240 that includes an outer annular
block 241, an inner annular block 242, and a central annular
stopper 243. The central annular stopper 243 forms a butting
accommodation slot 244 with the outer annular block 241 and the
inner annular block 242 respectively.
[0045] During the assembling process, the butting fastening groove
231 corresponds to the central annular stopper 243 and accommodates
the central annular stopper 243 therein. The central annular
stopper 243 bears against the face plate 210 and they are squeezed
with each other, so that the central annular stopper 243 is pressed
by the squeezing force and deformed, and thus engages with the
butting fastening groove 231. The butting accommodation slot 244
accommodates the protruding part of the butting fastening portion
230, and the outer annular block 241 and the inner annular block
242 bear against the outer side of the butting fastening portion
230, so as to prevent slits from being generated at the joint
surface between the face plate 210 and the body 220.
[0046] FIGS. 8A and 8B are a schematic structural view and a
combined schematic structural view of a golf club head according to
a seventh embodiment of the present invention respectively, which
show the process of combining the face plate 210 with the body 220.
In this embodiment, the body 220 does not have the accommodation
slot 225 mentioned in the above embodiments. The face plate 210 has
the annular fastening portion 211. The annular fastening portion
211 includes a protrusion 214 and a fastening groove 212. The
protrusion 214 is used to define the fastening groove 212, and the
fastening groove 212 with a rectangle-shaped cross section is
disposed on the outer side of the annular fastening portion 211.
The body 220 has an annular stopper 223, and a flange 224 is
disposed on the top of the annular stopper 223.
[0047] During the assembling process, the annular stopper 223
corresponds to the fastening groove 212, and the face plate 210 is
pressed under an external force and squeezed towards the body 220.
In this embodiment, the position of the annular stopper 223
corresponds to the outer side of the annular fastening portion 211,
and the position of the fastening groove 212 corresponds to the
outer side of the annular fastening portion 211. The flange 224 is
disposed on the inner side of the annular stopper 223. The flange
224 bears against the face plate 210, and due to the continuous
squeezing between the face plate 210 and the body 220, the flange
224 is gradually deformed towards the direction of the fastening
groove 212, so as to form a catching portion 227 for being engaged
with the fastening groove 212, and thus making the face plate 210
and the body 220 closely combined.
[0048] FIGS. 9A and 9B are a schematic structural view and a
combined schematic structural view of a golf club head according to
an eighth embodiment of the present invention respectively. The
structure in this embodiment is similar to that of the seventh
embodiment in that the body 220 does not have the accommodation
slot 225. However, in this embodiment, the face plate 210 further
includes an annular strip 215 disposed on the outer side of the
annular fastening portion 211, and the distance between the annular
strip 215 and the protrusion 214 is sufficiently long for
accommodating the annular stopper 223. In addition, the fastening
groove 212 is disposed on the outer side of the annular fastening
portion 211, and the inner side of the annular fastening portion
211 has a step-like cross section.
[0049] During the assembling process, the annular stopper 223
corresponds to a corresponding position between the annular strip
215 and the protrusion 214, and the face plate 210 is pressed under
an external force and squeezed towards the body 220. The flange 224
bears against the face plate 210 so that the flange 224 is deformed
towards the direction of the fastening groove 212, so as to form
the catching portion 227 for being engaged with the fastening
groove 212. The annular strip 215 bears against the outer side of
the annular stopper 223, so that the annular stopper 223 is
accommodated between the annular strip 215 and the annular
fastening portion 211, and thus the face plate 210 and the body 220
are closely combined.
[0050] FIGS. 10A and 10B are a schematic structural view and a
combined schematic structural view of a golf club head according to
a ninth embodiment of the present invention respectively. The
similarity between this embodiment and the seventh embodiment is
that the body 220 does not have the accommodation slot 225.
However, in this embodiment, the annular fastening portion 211 of
this embodiment is disposed on the periphery of the face plate 210,
the annular stopper 223 is disposed correspondingly on the inner
side of the annular fastening portion 211, the fastening groove 212
is disposed on the inner side of the annular fastening portion 211,
and the flange 224 is disposed on the outer side of the annular
stopper 223.
[0051] During the assembling process, the annular stopper 223
corresponds to the fastening groove 212, and the face plate 210 is
pressed under an external force and squeezed towards the body 220.
The flange 224 bears against the face plate 210, and due to the
continuous squeezing between the face plate 210 and the body 220,
the flange 224 is gradually deformed towards the direction of the
fastening groove 212, so as to form a catching portion 227 for
being engaged with the fastening groove 212, and thus the face
plate 210 and the body 220 are closely combined.
[0052] FIGS. 11A and 11B are a schematic structural view and a
combined schematic structural view of a golf club head according to
a tenth embodiment of the present invention respectively. The
structure of this embodiment is similar to that of the eighth
embodiment, but in this embodiment, the annular strip 215 has an
inclined bottom part 216 gradually inclined from the outer side
edge of the annular strip 215 to the inner side edge of the annular
strip 215, and the thickness of the outer side edge of the annular
strip 215 is greater than that of the inner side edge of the
annular strip 215. The inclined bottom part 216 is opposite a
bearing surface 228 of the body 220, and the bearing surface 228 is
a plane.
[0053] During the assembling process, the outer side edge of the
inclined bottom part 216 firstly contacts the outer side edge of
the bearing surface 228 of the body 220, and an external force is
applied to press and thus deform the bearing surface 228 of the
body 220, so that the inclined bottom part 216 of the annular strip
215 and the bearing surface 228 of the body 220 are closely
adhered.
[0054] FIGS. 12A and 12B are a schematic structural view and a
combined schematic structural view of a golf club head according to
a eleventh embodiment of the present invention respectively. The
structure of this embodiment is similar to that of the tenth
embodiment, but in this embodiment, the annular strip 215 has a
step-like bottom part 217 with a pressing block 218 disposed on the
outer side edge thereof. The step-like bottom part 217 is opposite
a bearing surface 228 of the body 220, and the bearing surface 228
is a plane.
[0055] During the assembling process, the pressing block 218
firstly contacts the outer side edge of the bearing surface 228 of
the body 220, and an external force is applied to press the bearing
surface 228 of the body 220 so that it is deformed, and the
step-like bottom part 217 is also deformed accordingly, so that the
step-like bottom part 217 of the annular strip 215 and the bearing
surface 228 of the body 220 are closely adhered.
[0056] The face plate 210 can further include an annular strip
disposed on the inner side of the annular fastening portion. In
addition, besides the rectangle-shaped cross section mentioned in
the above embodiment, the fastening groove 212 can also have a
trapezoid-shaped, arc-shaped, straight V-shaped, or inclined
V-shaped cross section.
[0057] While the embodiments of the present invention have been
illustrated and described, various modifications and improvements
can be made by those skilled in the art. The embodiments of the
present invention are therefore described in an illustrative, but
not restrictive, sense. It is intended that the present invention
may not be limited to the particular forms as illustrated, and that
all modifications which maintain the spirit and scope of the
present invention are within the scope as defined in the appended
claims.
