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.

[First Embodiment]
[0020] 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.
[0022] 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.
[0023] 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.
[0024] 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.
[0026] Referring to FIG. 3, the protrusions 300a, 300b, and 300c are formed to have the same protruding height or different protruding heights.
[0027] 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.
[0028] 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.
[0029] 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).
[0030] Meanwhile, FIG. 5 is an enlarged front view showing various modifications of the midsole 140 and the protrusion 300.
[0031] Referring to FIG. 5(a), a midsole 140a is formed such that a lateral surface thereof is vertical.
[0032] Referring to FIG. 5(b), a midsole 140b is formed such that a lateral surface thereof is inclined downwards. The midsole 140 is formed such that an area thereof is increased in a direction from top to bottom.
[0033] Referring to FIG. 5(c), a midsole 140c is formed such that a lateral surface thereof protrudes convexly in an arc shape.
[0034] The midsole 140c may be formed such that a portion having the protrusion 300 bulges further outwards.
[0035] Of course, it should be noted that the shape of the outer surface of the midsole may be changed in various ways.
[0036] 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.
[0037] 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.
[0038] 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).
[0039] 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.
[0040] 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.
[0041] Thus, foreign substances are removed by scratching the clubface using the end of the protrusion 300a.
[0042] 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.
[0043] 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.
[0044] Thus, foreign substances are removed by scratching the clubface using the end of the protrusion 300b.
[Second Embodiment]
[0045] 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.
[0046] 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.
[0047] As described above, the plurality of protrusions 300 is formed in one row or in multiple rows.
[0048] The plurality of protrusions 300 is formed to have the same protruding height or different protruding heights.
[0049] 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.
[0050] 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.
[0051] 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.
[0054] Referring to FIG. 5(a), the midsole 140a is formed such that the lateral surface thereof is vertical.
[0055] 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.
[0056] Referring to FIG. 5(c), the midsole 140c is formed such that the lateral surface thereof protrudes convexly in an arc shape.
[0057] The midsole 140c may be formed such that the portion having the protrusion 300 bulges further outwards.
[0058] Thus, the surface of the clubface may be cleaned by rubbing the clubface (not shown) using the protrusion 300 while slightly lifting the foot.
[0059] 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.
[0060] By forming the arc-shaped part 310 as such, foreign substances may not adhere to the protrusion 300 and may be easily removed therefrom.
[0061] 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.
[0062] 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.

[0068] 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.
[0069] 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.
[0070] 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.
[0071] Thus, the surface of the clubface may be cleaned by rubbing the clubface (not shown) using the brushes 640 while slightly lifting the foot.
[0072] 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.
[0073] 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.
[0074] While the present disclosure has been described with reference to preferred embodiments, it is apparent to those skilled in the art that these embodiments have been described for illustrative purposes, and various changes and modifications may be made without departing from the spirit and scope of the present disclosure as defined by the appended claims.
