Description
TECHNICAL FIELD
[0001] The present disclosure relates to a golf shoe and a method
for manufacturing the golf shoe and, more particularly, to a golf
shoe which is worn during a golf game to protect the foot and
maintains a stable swing action, and a method for manufacturing the
golf shoe.
BACKGROUND ART
[0002] Unless otherwise indicated herein, contents described in
this section are not the related art to claims of this application.
Although contents are included in this section, they are not
admitted to be the related art.
[0003] A golf club is connected to a grip which is a handle portion
by a shaft, and a groove is formed in a surface of a clubface to
induce the spin and back spin of a golf ball. Several transverse
grooves formed in the surface of the clubface to spin or back spin
the golf ball are designed to induce the spin of the golf ball at
the moment of impact.
[0004] Thus, the surface and the groove formed on the golf clubface
play an important role in sending the golf ball to a desired place
or spinning the golf ball to send the golf ball in a desired
direction.
[0005] An iron face may be designed by collectively considering the
shape, position, depth of the surface or groove to induce a precise
iron shot by optimally maintaining the energy transfer effect to
the golf ball or the position of a hitting point depending on a
swing.
[0006] However, in the golf clubface designed in this way, a large
number of foreign substances are accumulated in the surface and
groove due to the repeated swing actions.
[0007] As the golf ball is worn, debris therefrom may be
accumulated in the groove, or particles or grains such as soil or
sand may be lodged and accumulated between the surface and the
groove during repeated iron-shot processes. Likewise, since the
golf clubface comes into contact with the surface of grass, the
grass or the like is accumulated in the surface and groove.
[0008] Meanwhile, during rounding, a golfer may make several
practice swings on the grass before actually hitting the ball. The
most effective result can be achieved by actually hitting the ball
while maintaining such a swing sensation.
[0009] However, after several practice swings, foreign substances
such as grass or soil are accumulated on the clubface. An addition
action (action for wiping the foreign substances of the clubface
with the hand and then wiping the hand with a golfer's clothes, or
action for wiping the clubface with a separate towel or the like)
for removing the foreign substances leads to damage to the swing
sensation which is obtained through the practice swing.
[0010] Due to the foreign substances on the golf clubface, the ball
is inevitably subjected to resistance when hitting the ball.
Depending on a difference in resistance, a large deviation in
hitting distance and direction and rotating force occurs, thus
causing psychological atrophy and a stiff swing. An unnatural swing
action leads to incomplete hitting. An additional action for
removing the foreign substances leads to damage to sensation which
is obtained through the practice swing.
[0011] Therefore, in order for a golfer to maintain a swing
sensation which is obtained through the practice swing, a surface
cleaning means capable of removing foreign substances from the
clubface with the smallest movement is required.
DISCLOSURE
Technical Problem
[0012] Therefore, the present disclosure is intended to provide a
golf shoe having a surface cleaning means that can remove foreign
substances from a clubface with the smallest movement so as to
stably maintain the sensation of a practice swing, and a method for
manufacturing the golf shoe.
Technical Solution
[0013] In order to accomplish the above objective, the present
disclosure provides a method for manufacturing a golf shoe, the
golf shoe including a sole composed of an outsole and a midsole;
and an upper formed on a top portion of the sole, the method
including a process of injection molding the midsole; and a process
of forming a plurality of protrusions on a front- or rear-side of a
lateral surface of the midsole.
Advantageous Effects
[0014] According to an embodiment of the present disclosure, it is
possible to remove foreign substances by rubbing a clubface on a
protrusion of a midsole, and it is possible to remove foreign
substances from the clubface only by the smallest movement, so that
the sensation of a practice swing can be maintained without being
negatively affected, thus enhancing athletic performance.

[0031] [First Embodiment]
[0032] A method for manufacturing a golf shoe according to the
first embodiment includes process a of injection molding a midsole
140, and process b of forming a plurality of protrusions 300 on a
front- or rear-side of a lateral surface of the midsole 140. Here,
the golf shoe includes a sole 100 composed of an outsole 120 and
the midsole 140, and an upper 200 formed on a top portion of the
sole 100.
[0033] The midsole 140 is formed by injecting a raw material into a
mold of a molding apparatus.
[0034] A plurality of grooves is formed in the mold to form the
protrusions 300. Thus, by injecting the raw material into the
plurality of grooves, the protrusions 300 may be formed on the
outer lateral surface of the midsole 140.
[0035] As shown in FIGS. 1 to 6, the golf shoe A1 according to the
first embodiment includes the sole 100 composed of the outsole 120
and the midsole 140, and the upper 200 formed on the top portion of
the sole 100. The plurality of protrusions 300 is formed on the
front- or rear-side of the outer lateral surface of the midsole
140.
[0036] As shown in FIG. 1, the plurality of protrusions 300 may be
formed on the outside of the outer lateral surface of the midsole
140. However, without being necessarily limited thereto, the
protrusions 300 may be formed on the outside of a right shoe and
the outside of a left shoe.
[0037] One or multiple protrusion(s) 300 may be formed in one row
or in multiple rows.
[0038] Referring to FIG. 3, the protrusions 300a, 300b, and 300c
are formed to have the same protruding height or different
protruding heights.
[0039] Further, the plurality of protrusions 300 formed in the
multiple rows each have a hemi-spherical shape. The protrusion 300a
of an upper row and the protrusions 300b and 300c of a low row have
different diameters and are formed of materials having different
hardness.
[0040] The protrusion 300a of the upper row and the protrusions
300b and 300c of the low row may be formed such that large-diameter
protrusions and small-diameter protrusions are mixed.
[0041] The protrusion 300a of the upper row is formed to be smaller
in length than the protrusions 300b and 300c of the low row (see
FIG. 3).
[0042] Meanwhile, FIG. 5 is an enlarged front view showing various
modifications of the midsole 140 and the protrusion 300.
[0043] Referring to FIG. 5(a), a midsole 140a is formed such that a
lateral surface thereof is vertical.
[0044] Referring to FIG. 5(b), a midsole 140b is formed such that a
lateral surface thereof is inclined downwards.
[0045] The midsole 140 is formed such that an area thereof is
increased in a direction from top to bottom.
[0046] Referring to FIG. 5(c), a midsole 140c is formed such that a
lateral surface thereof protrudes convexly in an arc shape.
[0047] The midsole 140c may be formed such that a portion having
the protrusion 300 bulges further outwards.
[0048] Of course, it should be noted that the shape of the outer
surface of the midsole may be changed in various ways.
[0049] Thus, in the case of a right-handed person, foreign
substances may be removed by scratching a clubface (not shown)
using the protrusion 300 while slightly lifting the golf shoe of
the right foot.
[0050] Meanwhile, as shown in FIG. 11, according to a fifth
embodiment, the protrusion 300a is formed long on the outside of
the midsole 140 in an arc shape to have a predetermined length.
[0051] The protrusion 300a is formed long in a section ranging from
a start portion (portion corresponding to the toe and the upper end
of the drawing) to an end portion (portion corresponding to the
midsection of the foot and the middle portion of the drawing).
[0052] Preferably, the protrusion 300a is formed adjacent to the
midsole while a width thereof is gradually reduced at the start
portion or the end portion.
[0053] When seen from the front, the protrusion 300a has on an
upper portion thereof a curved surface 301a, so that the protrusion
protrudes out towards an end to be pointed, a lower portion thereof
being formed horizontally.
[0054] Thus, foreign substances are removed by scratching the
clubface using the end of the protrusion 300a.
[0055] Meanwhile, as shown in FIG. 12, according to a sixth
embodiment, a plurality of protrusions 300b is formed on the
outside of the midsole 140 in a section from the toe to the foot
midsection to be spaced apart from each other at a predetermined
gap.
[0056] When seen from the front, the protrusion 300b has on an
upper portion thereof a curved surface 301b, so that the protrusion
protrudes out towards an end to be pointed, a lower portion thereof
being formed horizontally.
[0057] Thus, foreign substances are removed by scratching the
clubface using the end of the protrusion 300b.
[0058] [Second Embodiment]
[0059] A method for manufacturing a golf shoe according to the
second embodiment includes a process of injection molding a midsole
140, and a process of forming a plurality of protrusions 300 on a
front- or rear-side of a lateral surface of the midsole 140 by
double injection molding. Here, the golf shoe includes a sole 100
composed of an outsole 120 and the midsole 140, and an upper 200
formed on a top portion of the sole 100.
[0060] Preferably, the plurality of protrusions 300 is made of a
material different from that of the midsole 140. For example, the
protrusion 300 may be formed of a material having strength higher
than that of the midsole 140.
[0061] As described above, the plurality of protrusions 300 is
formed in one row or in multiple rows.
[0062] The plurality of protrusions 300 is formed to have the same
protruding height or different protruding heights.
[0063] A golf shoe A2 according to the second embodiment includes
the sole 100 composed of the outsole 120 and the midsole 140, and
the upper 200 formed on the top portion of the sole 100. The
plurality of protrusions 300 formed of a material different from
that of the midsole 140 is formed by double injection molding on
the front- or rear-side of the outer lateral surface of the midsole
140.
[0064] The plurality of protrusions 300 formed in the multiple rows
each have a hemi-spherical shape. The protrusions 300 of an upper
row and the protrusions 300 of a low row have different diameters
and are formed of materials having different hardness.
[0065] The protrusions 300 of the upper row and the protrusions 300
of the low row may be formed such that large-diameter protrusions
and small-diameter protrusions are mixed.
[0066] The protrusion 300 of the upper row is smaller in length
than the protrusion of the low row.
[0067] FIG. 5 shows various modifications of the midsole 140 and
the protrusion 300.
[0068] Referring to FIG. 5(a), the midsole 140a is formed such that
the lateral surface thereof is vertical.
[0069] Referring to FIG. 5(b), the midsole 140b is formed such that
the lateral surface thereof is inclined downwards. The midsole 140
is formed such that the area thereof is increased in a direction
from top to bottom.
[0070] Referring to FIG. 5(c), the midsole 140c is formed such that
the lateral surface thereof protrudes convexly in an arc shape.
[0071] The midsole 140c may be formed such that the portion having
the protrusion 300 bulges further outwards.
[0072] Thus, the surface of the clubface may be cleaned by rubbing
the clubface (not shown) using the protrusion 300 while slightly
lifting the foot.
[0073] Meanwhile, as shown in FIGS. 5 and 6, an arc-shaped part 310
is formed in a curved manner on a portion where an outer surface of
the midsole 140 and the protrusion 300 thereof are connected.
[0074] By forming the arc-shaped part 310 as such, foreign
substances may not adhere to the protrusion 300 and may be easily
removed therefrom.
[0075] Furthermore, a vent hole 330 is formed in the protrusion
300, and an air passage 320 is formed to pass through the midsole
140 and an insole 150, thus allowing ventilation while walking.
[0076] Thus, when foot is set on the ground, internal air is
discharged through the air passage 320 and the vent hole 330, so
that foreign substances on the protrusion 300 may be removed by
blowing the air.
[0077] [Third Embodiment]
[0078] A method for manufacturing a golf shoe according to a third
embodiment includes a first process of injection molding a midsole
140; and a second process of planting brushes 500 into a front- or
rear-side of a lateral surface of the midsole 140 before the
midsole 140 is cured. Here, the golf shoe includes a sole 100
composed of an outsole 120 and the midsole 140, and an upper 200
formed on a top portion of the sole 100.
[0079] As shown in FIGS. 7 and 8, a golf shoe A3 according to the
third embodiment includes the sole 100 composed of the outsole 120
and the midsole 140, and the upper 200 formed on the top portion of
the sole 100.
[0080] The brushes 500 are formed on a front- or rear-side of an
outer lateral surface of the midsole 140.
[0081] Preferably, the brushes 500 are formed in different
thicknesses and lengths.
[0082] Thus, the surface of the clubface may be cleaned by rubbing
the clubface (not shown) using the brushes 500 while slightly
lifting the foot.
[0083] [Fourth Embodiment]
[0084] A method for manufacturing a golf shoe according to a fourth
embodiment includes a first process of forming a hole 142 in a
lateral surface of a midsole 140; and a second process of fitting a
protrusion member 600 into the hole 142. Here, the golf shoe
includes a sole 100 composed of an outsole 120 and the midsole 140,
and an upper 200 formed on a top portion of the sole 100.
[0085] As shown in FIG. 9, a golf shoe A4 according to the fourth
embodiment includes the sole 100 composed of the outsole 120 and
the midsole 140, and the upper 200 formed on the top portion of the
sole 100. A plurality of protrusion members 600 is detachably
coupled to an outer lateral surface of the midsole 140.
[0086] Meanwhile, as shown in FIG. 9, each protrusion member 600
includes a pointed conical part 620 fitted into the hole 142, and a
hemi-spherical projecting part 630 formed on another side of the
conical part 620. A plurality of brushes 640 is planted into an
outer surface of the hemi-spherical projecting part 630.
[0087] Thus, the surface of the clubface may be cleaned by rubbing
the clubface (not shown) using the brushes 640 while slightly
lifting the foot.
[0088] Meanwhile, as shown in FIG. 10, according to another
embodiment, the protrusion member 600 may include a plate member
650 having on one side surface thereof a plurality of fitting tips
652 that each are fitted into the hole 142, and a plurality of
brushes 640 formed on the other side surface of the plate member
650.
[0089] Therefore, the surface of the clubface may be cleaned by
rubbing a clubface (not shown) held in the right hand using the
brushes 640 while slightly lifting the golf shoe of the right
foot.
[0090] While the present disclosure has been described with
