Abstract

PURPOSE:To attain an ideal swinging by making a rear side shoe sole in the direction of ball hitting into a double structure composed of a hard sale and a soft elastic sole, and providing a inclination holding part of the hard sole in the rear side soft shoe sole is so as to make the rear side edge of the shoe higher than the front side edge of it. CONSTITUTION:A shoe sole part 2 is composed by a soft bottom 4 having an elasticity on a hard sole 3 and the upper surface of the soft sole 4 is formed in a horizontal shape. An inclination holding part 5 is formed to a flat plate shape, angle bar shape, round bar shape, inclination plate, etc., with a hard material so as to be packaged into the soft bottom 4. For the height of the inclination holding part 5, 10 or 25mm are preferably optimum. At the time of walking, the feeling of much inclination and incompatibility does not occur, and at the time of hitting a ball, a foot becomes a kicking state against the rear side edge, the force of the foot is added to the front side edge and the soft shoe 4 is strongly suppressed. At this time, though naturally the force is added to the rear side edge, the sinking due to the suppression is prevented by the inclination holding part 5, the front side edge largely sinks, the angle of alphais created at a body through a foot 7 and the force equivalent to a body weight transferring DELTAW is created.

Description

DETAILED DESCRIPTION OF THE INVENTION A. Field of Industrial Application The present invention relates to golf shoes, and is designed and improved so that general golf players can swing shots at the ball more accurately and reliably. It's related to the golf shoes I went to.

2. Description of the Related Art Figure 1 shows the trajectory of an ideal golf swing. This principle is well known. However, even for many amateur golfers, it is not easy to swing as shown in Figure 1. In many cases, as shown in Figure 2, in the initial backswing,
This is generally the case when a movement involving the body's axis, that is, a body sway phenomenon occurs. In the ideal swing shown in Figure 1, the swing starts from point rSJ, the radius of rotation R decreases to rSJ-+rTJ → rHJ, and the club is pushed out horizontally by ΔX, and the apogee of club rotation becomes R+ΔX and rFJ to move to. On the other hand, when the body sways as shown in Figure 2, the backswing moves from point fTJ and rHJ by ΔX, and the swing starts from point rSJ and moves from rSJ → rTJ → "Ho".
→rHJ−→rFJ, and the apogee of club rotation is R−Δ
The swing becomes smaller than the ideal swing (R-
(Δχ×ΔX°)). The time to actually hit the ball is delayed by the amount of movement of the body relative to ΔX, and when hitting the ball, the ball is hit at a point higher by ΔY as shown in the second figure, and at a point that is higher than the club face by an angle of θ as shown in the fourth figure. , the situation is (L+0) added to the loft angle of the club (see Figure 5).

For this reason, the horizontal force F in the ideal swing (Fig. 3) in Fig. 1 has an angle θ as shown in Fig. 4, resulting in a force F'.

The force becomes smaller by ΔF. That is, F'>F' and F
The relationship =ΔF+F' holds true. As shown in Fig. 5, this car shows that the flying distance is shorter than the ideal flying distance diagram (a) as shown in (b). This relationship (
Shown in c). Next, we will show the relationship between the position of the player's feet and their position when keeping the ball. Figure 6 shows the relationship rHJ between the ideal stance and the position of holding the ball, and Figure 7 shows rS when the body of a right-handed player moves by △R towards the right foot.
The positional relationships of J, rHJ, and "Ho" are shown, respectively.

C. Problems to be solved As mentioned above, when an ordinary player makes a backswing to hit the ball, the ideal swing situation may sway to the rear side, that is, for a right-handed golfer, to the right foot side. As a result, the flight distance is not determined, the time at which the ball is hit is not determined, and the direction in which the ball is launched is also not determined.

21 Means for Solving Problems Therefore, in the present invention, when making a backswing, a right-handed batter can make an ideal swing without swaying to the right side from an ideal swing state. In order to do so, it is offset by applying a force in the opposite direction corresponding to the movement of the body weight when swaying.

In order to prevent sway, golf shoes are designed to hold the end of the foot in one direction high when swaying, and the shoe does not tilt during normal walking, but only maintains the slope during shots. In this proposal, the sole of the shoe on the rear side in the ball hitting direction has a double structure of a hard sole and a soft sole made of elastic material placed on top of the hard sole, and the rear end of the soft sole is higher than the front end. It is characterized by providing an inclined holding part made of a hard material for holding.

E, Example The present invention will be explained in detail below with reference to embodiments shown in the figures.

Figures 8 and 9 show different foot situations with the position and angle of the foot of a right-handed player. Figure 8 shows a normal stance with the left and right shoes along the ground, and Figure 9 shows a stance with the right foot at an angle α to the ground.

Suppose that the weight on the player's right foot is W. In the case of the stance horizontal to the ground in Figure 8, the weight W is applied perpendicular to the ground, whereas in the case of Figure 9, as shown in Figure 10, the weight is applied at an angle of α to the ground. Because it is perpendicular to the plane with , that is, the x-x' plane.

The weight W has an angle α with respect to FIG. 8 and is perpendicular to the plane x-x'. Therefore, in the case of Figure 9, that is, when only the right foot holds the angle α, the weight shift △W produced by the angle α from the right foot to the left foot will occur. In other words, the force generated from the right foot to the left foot of this △W is
As explained in Figures 1 to 7, when an ordinary player makes a backswing to hit the ball, the situation in which the player's body moves from the ideal swing to the right side is determined by the amount of weight movement. The opposite force ΔW corresponding to
By offsetting this, the more ideal swing shown in Figure 1 can be easily realized in the situations shown in Figures 9 and 10 without causing the player's body to sway.

However, when tilting the shoe on the rear side in the ball hitting direction, it is natural to tilt the shoe on the front side as well, and it is expected that there will be a countervailing force that synergizes with the countervailing force of △W at the same time,
There are three forms as follows:

Among these, the case where α〉α゛ is the most effective.

Therefore, Maximum effectiveness can be achieved when

A specific example of an inclined holding part that actually realizes the situation shown in FIGS. 9 and 10 of the present invention is shown in FIGS. The golf shoe worn on the right foot of a hitting player will be explained. Regarding the golf shoes for the left foot, there are cases in which conventional ones are used, and there are cases in which they are formed in accordance with the golf shoes for the right foot of the present invention, but with a lower height. The golf shoe is a schematic diagram seen from the heel. Fig. 13 shows the sole of a conventional golf shoe 1, in which the sole λ is flat and has spike fittings 6 screwed into it.In the present invention, the sole λ is made of leather, synthetic leather, It is constructed by providing a soft sole 4 made of elastic plastic, soft rubber, etc. on a hard sole 3 made of synthetic rubber or the like. The upper surface of the soft sole 4 is formed horizontally. The soft sole 4 is preferably fixed on the hard sole 3, but may simply be placed on it. 5 is an inclined holding part, which can be made of hard rubber, plastic, wood, iron, metal such as aluminum, etc. Made of hard material, it is formed in the shape of a flat plate, square bar, round bar, slanted plate, etc. The inclined holding part 5 is installed so as to be wrapped in the soft sole 4, but the heel part and the foot part may be formed separately and attached, or it may be formed in one piece over an appropriate length. Moreover, the inclined holding part 5 can be installed to be curved to match the outer surface of the sole of the shoe or to match the shape of the foot. Of course, the soft sole 4 may be formed integrally, or the heel portion and the foot portion may be formed separately. The height of this inclined holding part 5 is preferably 5 to 40 mm, preferably 10 to 25 mm. Also soft sole 4
Of course, a bedding layer may be placed on top.

The shoes are used in the same way as ordinary golf shoes, but when the foot 7 rests on the soft sole 4, the soft sole 4 is pressed and compressed by one body weight. In this case, the soft sole 4 is formed to be thinner because the rear end is compressed more than the front end due to the inclined field holding part 5 provided at the rear end in the ball hitting direction.
Although it is slightly tilted toward the front end, the pressure when walking is not as great as that of the husband, and the heights of the front and back are slightly different. Therefore, when walking, there is no inclination as much as the husband's, and there is no discomfort.However, when hitting a ball, the foot kicks toward the rear end, and the force of the foot is applied to the front end, strongly pressing the soft sole 4. At this time, of course, force is applied to the rear end, but it hits the inclined holding part 5, preventing it from sinking due to further pressure, and as a result, the front end sinks greatly and is applied to the body via the foot 7 as shown in Fig. 13. An angle α is created, and a force corresponding to the weight shift ΔW is created.

Functions and Effects of the Invention According to the invention as described above, the sole of the shoe on the rear side in the ball hitting direction has a double structure of a heart sole and a soft sole made of an elastic material provided thereon. A tilting holding part made of a hard material is provided on the rear end of the sole to hold it higher than the front end, so when walking, your foot rests on the sole in almost the same way as regular golf shoes, and you won't feel any discomfort. In the case of a right-handed golf player, the sloping holding part provided on the right edge of the right side allows the front end to sink deeply and the rear end to compress the soft sole of the foot when shooting the ball. Because this is blocked, it is performed in a state where it is tilted toward the front end. Therefore, by making the swing extremely accurate and increasing the flight distance of the ball as shown in Figures 1 to 5, and by modifying the swing situation as shown in Figure 6, you can slice and swing in the target direction. etc., and the directionality can be significantly improved.

In addition, the present invention is not only suitable for right-handed players, but also allows the soles of both feet to have different thicknesses and angles in the same direction.
Enhance similar effects and produce more effective results.
