Patent Application
20210337929
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
Hereinafter, preferred embodiments will be described in detail with reference to the accompanying drawings.
Embodiments of the present disclosure will be described in detail such that those skilled in the art can easily practice the present disclosure. However, the present disclosure may be implemented in various ways without being limited to particular embodiments described herein.
Furthermore, the size or shape of components shown in the drawings may be exaggerated for the clarity and convenience of description. Since terms can be differently defined according to the intention of a user or an operator or customs, these terms should be interpreted as having a meaning that is consistent with the technical spirit of the present disclosure.
