Description

Anti-sway golf shoes.

The present invention relates to golf shoes, and in particular, prevents sway during the backswing during a golf swing while maintaining a uniform feeling of support delivered to the sole of the foot during a takeaway throughout 18 holes.

Golf shoes currently worn when playing golf have studs (a general term for protrusions made of plastic or rubber) protruding from the outsole to prevent slipping on the grass.

However, the studs of these golf shoes were used only for the purpose of preventing slipping on the tee box or grass such as the fairway or rough during the golf swing, not only during the backswing, but also during the downswing, impet, or follow-through.

In addition, the basic pattern in the golf swing consists of the address, back swing, and top swing after taking a stance, followed by a downswing, impact, follow-through, and finish. The most important thing is that the lower body is strong when doing the takeaway for the backswing at address. The shoulder turn is performed in a well-supported state. At this time, the lower body, especially the knees, must not be pushed in the takeaway direction. There is enough twist by separating the upper and lower body to produce a uniform, accurate, and strong impact with the downswing using the lower body. This makes it possible to hit the golf ball accurately at the sweet spot of the golf club head.

In other words, the basic stage of the golf swing can be said to be the start of the golf swing from the address, which is called the basic posture of the golf swing. The exact path of the swing trajectory is determined depending on whether this start is straight or not, especially the starting stage of the backswing. As the takeaway is made accurately, the opening and closing of the head of the golf club is determined at the top, which determines the ease or discomfort of dropping the club directly downward or rotating the body (pelvis) during the downswing, which is the starting stage for hitting the ball. It is possible.

Therefore, it can be seen that these comforts and inconveniences greatly affect the result of the shot depending on which part of the body is used and how the power is used. In particular, at impact, the opening and closing of the club head is affected in the area where the golf ball and the club head meet. Accordingly, the direction of the ball is determined and whether the force is transmitted accurately. In the follow-through immediately after impact, the movement of the club head toward the target point generates centrifugal force in the golf swing, allowing the club to be sent in the target direction.

Therefore, the finish at the end of the golf swing is not a movement made intentionally, but is achieved automatically by the centrifugal force of the follow-through, so if this finishing posture is not performed properly, it can be seen that the golf swing is not performed properly.

Among these, especially during a takeaway, whether the lower body, especially the knees, are pushed in the direction of the takeaway (sway) can be seen as the most important point in the golf swing.

Therefore, in order to prevent this sway, ordinary amateurs apply force to the inside (inner line) of the sole of the foot while placing the center of gravity on the sole of the foot while taking a stance (address) through strength training or practice. In this case, if they make a mistake, the reverse occurs. Even if there is a problem with the pivot phenomenon or no sway occurs during the takeaway, it is impossible for an ordinary amateur to maintain this movement throughout 18 holes.

Therefore, it has recently been proposed to change the structure of the sole (midsole) of golf shoes to prevent sway during takeaway, but this structure simply causes the outer line (rim) of the sole to slope outward and protrude more, thereby preventing the takeaway. When away, this more protruding part improves support and prevents the lower body from sliding.

However, although this structure can prevent the inner line of the sole of the right foot from being lifted during a takeaway, there is a problem in that it is not enough to keep the knee facing forward when the bottom surface of the golf shoe sole remains flat.

To this end, the present invention provides comfort when walking, improves the support of the right foot during the takeaway for the backswing, prevents sway (shape where the knee is pushed), and also provides support for the left foot during downswing, impact, and follow-through. This prevents sway and supports the left foot while making it possible to maintain sensation throughout the 18-hole round.

For this purpose, the outsole is separated into the inner and outer surfaces of the bottom of the golf shoe sole (midsole) and attached to each with a separation space in the center. The outsole is provided with a through hole to penetrate laterally, and the edge of the through hole is provided. In other words, a certain thickness of flesh is provided, and a stud is provided to protrude on the exposed surface exposed to the outside while the outsole is attached to the midsole.

In addition, the outsole separates the forefoot and heel parts of the sole and is spaced apart on the inner and outer surfaces, respectively.

In addition, when the outsole is attached to the inner and outer surfaces of the bottom of the midsole, an inner groove is provided so that the outsole can be inserted when a separation space is formed in the center, so as to improve the ease and stability of attachment, as well as the inner and outer sides. Reinforcement ribs are provided at a certain height in the space between the outsole attached to the outer surface.

In addition, with the outsole attached, the through hole of the outsole attached to the outer surface of the sole is gradually expanded up and down from the inner to the outer so that more support can be felt on the outer surface of the sole than on the inner surface during the backswing or downswing with the outsole attached. It was meant to be lost.

In addition, the through hole is formed in an oval shape to provide a constant repulsion force during support and repulsion to provide a stable ground repulsion force.

In addition, when the outsole is made up of multiple stages up and down on the forefoot and heel, each block of the outsole forming the multistage is connected with a curved part to facilitate the adhesion of the outsole by interlocking the through-holes of the outsole provided with each block. It works excellently.

In addition, when forming a through hole for attaching the outsole to the outer surface, the inner diameter of the through hole is the same or the through hole is expanded outward, and the thickness of the flesh forming the through hole is made thick to increase elastic strength. By making it stronger than the one attached to the side, it is possible to prevent sway of the right foot or improve left foot support.

Therefore, when making a takeback for a golf swing, if you are right-handed, pressure is transmitted to the outer line of the sole of your right foot, causing sway in which your right knee is pushed outward, and this sensation can be maintained continuously. This makes it possible to sensibly prevent sway, and the pressure on the outer line is reduced by the cushion of the grass when walking, providing comfort when walking. Additionally, when walking for a long time, the cushion of the tube body Fatigue can also be prevented through exercise.

The best form for carrying out the present invention is to divide the forefoot portion of the golf shoe sole (hereinafter referred to as midsole) into an inner and outer side, provide a separation space in the center, and place the outsole on the inner and outer sides of the forefoot portion of the midsole, respectively. Attach them spaced apart,

The outsole has a through hole to penetrate laterally,

Meat of a certain thickness is provided along the edge of the through hole,

With the outsole attached to the inner and outer surfaces of the forefoot of the midsole, a stud is provided to protrude on the exposed surface exposed to the outside.

In the worn state, when a load is applied and pressed by the through hole of the outsole, the inner line of the outsole provided on the left and right of the space is the outer line. When the weight of the sole is concentrated and pressed, the inner line of the outsole is These are anti-sway golf shoes that are pressed more than the outer line and naturally transmit support to the outer side of the sole, preventing sway of the right foot during the backswing and improving support of the left foot during the downswing and impact.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

As shown in Figures 1 to 7, the configuration of the present invention divides the bottom of the golf shoe sole (also called midsole) 100 into a forefoot part 110 and a heel part 120, and is used only in the forefoot part 110. When wearing golf shoes, the sole is divided into two equal parts, the inner surface 111 and the outer surface 112, and a separation space 10 is provided in the center, and the outsole 200 is placed on the inner and outer surfaces of the forefoot, respectively. Attached, the outsole 200 is provided with a through hole 210 so as to penetrate laterally, and flesh 220 of a certain thickness is provided along the edge of the through hole, and a nail is formed on the exposed surface of the outsole 200. (230) is provided to protrude.

Therefore, when a load is applied and pressed by the through hole 210 of the outsole 200 in a worn state, the inner line 201 of the outsole 200 provided on the left and right forms a separation space 130. When the weight of the sole of the foot is doubled and pressed against the outer line (202), the inner line (201) of the outsole is pressed more than the outer line (202), naturally generating support resistance on the outer line (202) during the backswing. In addition to preventing sway of the right foot, the support of the left foot during downswing and impact can also be improved.

At this time, the heel part 120 is divided into an inner surface 121 and an outer surface 122 in the same way as the forefoot part 110, and an outsole 200a is attached to each with a separation space 20 formed in the center thereof. In the case of wearing golf shoes, the support of the sole is concentrated more in the center, and the inner lines (201, 201a) of the outsole are pressed more than the outer lines (202, 202a), so that the heel (120) is pressed rather than only the forefoot (110). ), so a more natural support can be generated.

In addition, when the outsole (200, 200a) is attached to the inner and outer surfaces of the bottom of the midsole and a separation space (10, 20) is formed in the center, the outsole (200, 200a) can be inserted into an internal groove ( 130), so as to facilitate the attachment of the outsole (200, 200a) and stability after attachment, as well as the midsole in the space (10, 20) of each outsole attached to the inner surface (111) and the outer surface (112). The reinforcing spokes 131 protruding from (100) are provided at a certain height so that the outsole (200, 200a) is not crushed when a direct load is generated by the through hole 210 penetrated laterally. It is designed to maintain stable elasticity while controlling the degree of elasticity.

In addition, with the outsole attached, the through hole 210 of the outsole attached to the outer surface of the midsole is attached to the midsole so that more support can be felt on the outer surface of the sole than on the inner surface during the backswing or downswing. Takeaway for a backswing at address while wearing golf shoes by gradually expanding from the inner line to the outer line, or expanding only a certain length of the outer line and spreading it upward and downward, that is, by making the inner diameter of the outer line larger than the inner diameter of the inner line. This is to prevent sway caused by natural support by allowing the support force transmitted to the sole of the foot to be transmitted to the outer line of the outsole and to feel supported.

In addition, the through hole of the outsole is made in an oval shape rather than a circle if possible to provide a constant repulsion force during support and repulsion to stably provide a ground repulsion force in the golf swing.

In addition, when the outsole is attached to the forefoot and heel of the midsole, in the case where it is made up of multiple stages up and down in the form of a block, each block of the outsole forming the multistage is connected with a curved part to attach the outsole to the midsole. The adhesion work is facilitated by the fact that the interlocking action of the through holes of the outsole provided in each block is integrated by the bending portion.

Even in this case, ease of adhesion and stability can be provided by providing an inner insertion line so that the curved parts can be seated at the top and bottom of the inner portion.

At this time, the outsole attached to the toe of the midsole does not form a space, but can be used as a single outsole by connecting it in multiple stages at the top and bottom through bends. In this band, a through hole passes through the side of the outsole from the inner line to the outer side. The purpose of the present invention can be achieved only when used by expanding the line.

In addition, when attaching an outsole to the forefoot or heel of a midsole, when forming a through hole in the outsole attached to the outer surface, the through hole is formed with the inner diameter of the through hole being the same or with the through hole being expanded outward. By making the thickness of the outer sole thicker, when the support force of the outsole occurs, the elastic strength is stronger than that attached to the inner side, thereby preventing sway of the right foot or improving the support power of the left foot.

Figure 8 is to induce easy attachment when the outsole of the present invention is attached to the midsole. When the midsole is provided with a groove line (1) and the outsole is provided with a protruding line (2) for primary insertion and adhesion. This is to provide ease of adhesion.
