Description

[Detailed description of the invention]

B. Field of Industrial Application The present invention relates to golf shoes, and relates to golf shoes that have been devised and improved so that general golf players can swing shots toward the ball more accurately and reliably when playing golf. . B. Prior Art FIG. 1 shows the trajectory of a typical 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 FIG. 2, during the initial backswing, movement including the body axis, that is, a body sway phenomenon generally occurs. In the ideal swing shown in Figure 1, the swing starts from point ``S'', moves down from ``S'' to ``T'' to ``H'' with a radius of rotation R, and the club is pushed out horizontally by ΔX. The apogee of club rotation becomes R+ΔX and shifts to "F". On the other hand, when the body sways as shown in Figure 2, the points "T" and "H" move by ΔX during the backswing, and the swing starts from point "S" and moves from "S" to "H". T'→'H''
→ “H” → “F”, and the apogee of club rotation is R
+ΔX', and compared to the ideal swing, the swing becomes [R-(ΔX+ΔX')]. The time to actually hit the ball is delayed by the amount of movement relative to ΔX of the body, and when hitting the ball, ΔY as shown in the second diagram.
As shown in Figure 4, the club face is at a higher point than the loft angle L of the club by an angle θ.
The situation becomes (L + θ) (fifth
(see figure). For this reason, the horizontal force F in the ideal swing (Fig. 3) in Fig. 1 has an angle of θ as shown in Fig. 4, resulting in a force F' and ΔF.
becomes smaller by the force of That is, F>F' and F=
The relationship ΔF+F' holds true. This shows that compared to the ideal flight distance chart a as shown in FIG. 5, the flight distance becomes shorter as shown in b. This relationship is 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 ``H'' between the ideal stance and the position of the ball, and Figure 7 shows ``S'', ``H'', and ``H'' when the body of a right-handed player moves toward the right foot by ΔR. '''
The positional relationship of each is shown. C. Problems to be solved As mentioned above, when an ordinary player performs a backswing to hit the ball, a situation occurs where the swing sways from the ideal swing situation to the rear side, that is, to the right foot side for a right-handed golfer. , As a result, the flight distance is not good and the direction in which the ball is launched is not determined. D. Means for solving the problem Therefore, in the present invention, when performing 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 prevent sway by applying a force in the opposite direction corresponding to the movement of the body weight when swaying, and to prevent swaying, the end of the foot in the swaying direction is held high, and We propose golf shoes that do not have an inclination during normal walking, but maintain an inclination only when shooting.
It is composed of two stages: a hard bottom and a soft bottom. The hard bottom is formed to be higher toward the rear end in the ball hitting direction to form an inclined holding part, and the soft bottom made of an elastic material is placed on top of the hard bottom so that the upper surface is horizontal. It is characterized by having been provided. E. Examples The present invention will be explained in detail with reference to examples shown in the figures below. Figures 8 and 9 show different foot situations with the position and angle of the foot of a right-handed player.
In the case of Fig. 8, the left and right shoes are taken in a normal stance along the ground, and in the case of Fig. 9, the right foot is shown in a stance with 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, the weight is at an angle α to the ground as shown in Figure 11. Therefore, the weight W is perpendicular to the plane XX' at an angle α with respect to FIG. Therefore, in the case of Fig. 9, that is, when only the right foot holds the angle α, a weight shift ΔW generated by the angle α will occur from the right foot to the left foot. In other words, the force generated from this ΔW from the right foot to the left foot is, when an ordinary player performs a backswing to hit the ball as explained in Figures 1 to 7, the player's body moves away from the ideal swing. The situation of moving to the right image is expressed by the opposite force ΔW corresponding to the weight movement.
As a result, the more ideal swing shown in FIG. 1 can be easily realized in the situations shown in FIGS. 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.
Moreover, it is possible to expect a countervailing force that synergizes with the above-mentioned countervailing force of ΔW, and there are the following three forms.

[Table] Of these, the effect is greatest when α>α'. Therefore,

The maximum effect can be ensured when [Table]. 13 to 15 show specific examples of the inclined holding portion that actually realizes the situations shown in FIGS. 9 and 10 of the present invention.
As shown in the figure. The same applies to the following, but in this embodiment, a golf shoe on the right foot side of a right-handed player will be described. As for the golf shoes on the left foot side, there are cases in which conventional ones are used, and there are cases in which they are formed in accordance with the golf shoes on the right foot side of the present invention, but with a lower height. Golf Shoes is a schematic diagram seen from the heel side. FIG. 13 shows the bottom of a conventional golf shoe 1. The bottom surface of the sole 2 is flat and has a spike fitting 6 screwed into it. The sole 2 is constructed by providing a soft sole 4 made of elastic plastic, soft rubber, etc. on a hard sole 3 made of leather, synthetic leather, synthetic rubber, or the like. The soft sole 4 is preferably fixed on the hard sole 3 with its upper surface horizontal, but it may also be simply placed on the hard sole 3. Reference numeral 5 denotes an inclined holding part, which is formed on the hard sole 3 or separately from the hard sole and fixed thereon;
Made of hard materials such as hard rubber, plastic, wood, iron, metal such as aluminum, etc., in the shape of a flat plate, square bar, round bar, etc.
It is formed on an inclined plate, etc. The inclined holding part 5 is installed so that its surface is covered by the soft sole 4, but the heel part and the foot part may be formed and attached separately,
It may be formed in one piece over an appropriate length. Further, the inclined holding part 5 can be installed so as to be curved to match the outer surface of the sole part 2 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. Moreover, it goes without saying that a padding material may be laid on the soft sole 4. It is used in the same way as regular golf shoes, but when the foot 7 rests on the soft sole 4, the soft sole 4 is pressed and compressed by the body weight. At this time, due to the inclined holding part 5 provided at the rear end in the ball hitting direction, the soft sole 4 is formed thinner at the rear end than at the straight end, and the compressed part is thinner, so the front end tends to sink deeper and the front and rear heights are lowered. It becomes slightly unbalanced. Therefore, although I can tilt a little when walking, I don't feel as uncomfortable as my husband. However, when hitting the ball, the foot kicks toward the rear end, and the force of the foot is applied to the front end.
Press down firmly on the soft sole 4. At this time, of course, force is applied to the rear end, but it hits the inclined holding part 5 and prevents 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 α as shown in FIG. 101. An angle of ΔW is generated, and a force corresponding to the weight shift ΔW is generated. F. Functions and Effects of the Invention According to the present invention as described above, the sole of the shoe on the rear side in the direction of ball hitting is structured into two stages: a hard sole and a soft sole;
The hard sole is formed to be higher in the direction of the rear end in the ball hitting direction to form an inclined holding part, and the soft sole made of elastic material is provided on the hard sole so that the upper surface is horizontal, so it can be used normally when walking. Compared to the golf shoe shoes, there is a slight feeling of discomfort when the foot rests on the sole of the shoe, but it does not interfere with walking.If you are a right-handed golf player, the slanted holding part provided on the right edge of the shoe will help you when shooting the ball. The extent to which the soft sole of the foot is compressed is deep at the front end and blocked at the rear end, so it is performed in a state where it is inclined toward the front end. Therefore, by making the swing extremely accurate and increasing the flight distance of the ball as shown in Figs. 1 to 5, and by modifying the swing situation as shown in Fig. 6, it is possible to slice and swing in the target direction. Directionality can be significantly improved by suppressing hooks, etc. In addition, the present invention can enhance the same effect and produce effective results not only by changing the thickness and angle of the soles of both feet in the same direction, but also by changing the thickness of the soles of the right shoes of right-handed players.
