Description

DETAILED DESCRIPTION OF THE INVENTION A. Field of Industrial Application The present invention relates to golf shoes, and has been devised 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.

BACKGROUND OF THE INVENTION Figure 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 Figure 2, in the initial backswing,
Generally, movement including the body axis, ie, a body sway phenomenon occurs. In the ideal swing shown in Figure 1, the swing starts from point rS1, and the rotation -
``t[R-['rSJ → rTJ → rHJ, the club is pushed out horizontally by ΔX, and the apogee of club rotation becomes R + ΔX, shifting to rFJ. When swaying, the pax ink moves from point rTJ and fHJ by ΔX, and the swing starts from point rSJ and moves from point rSJ to point rsJ 4rTJ-r.
H' J-rHJ-rFJ, and the apogee of club rotation becomes small, approximately -ΔX゛.Compared to the ideal swing, the point beyond that becomes (R-(Δχ+ΔX゛)), only the moving platform relative to the body's moving platform ΔX. The time to actually hit the ball is delayed, and when hitting the ball, the club face is at a point ΔY higher as shown in the second diagram, and at an angle of 0 as shown in the fourth diagram, relative to the loft angle of the club. , the situation is the sum of (L10) (see Figure 5). Therefore, for the horizontal force F (Figure 3) in the ideal swing Figure 1, the force shown in Figure 4 is Since it has an angle of θ, it becomes a force F′, and Δ
The force of F becomes smaller. That is, F>F', and F=
The relationship ΔF+F' holds true. This shows that, as shown in FIG. 5, compared to the ideal flight distance diagram (a), the flight distance becomes shorter as shown in (b). This relationship is shown in (C). Figure 6 shows the relationship between the position of the player's feet and the position when holding the ball. Figure 6 shows the relationship rHJ between the ideal stance and the position of the ball. Figure 7 shows rsJ, rHJ, r)1' J(7) between positions 41+ when the body of a right-handed player moves toward the right foot by ΔR.

C. Problems that need to be solved As mentioned above, when a general player makes a backswing to hit the ball, a situation occurs where the swing sways from the ideal swing situation to the rear side, that is, for a right-handed golfer, to the right foot side. As a result, the flight distance is not great, and the direction in which the ball is launched is not determined.

21. Means for Solving Problems Therefore, in the present invention, when performing pax ink, a right-handed batter can make an ideal swing without swaying to the right side from an ideal swing state. To do this, when swaying, the end of the foot in one direction of the sway should be made higher so that the force in the opposite direction corresponding to the shifting platform of the weight is applied to cancel it out and prevent swaying. A golf shoe is proposed, which is characterized by having an inclined holding part for holding the rear end side of the shoe on the rear foot side in the ball hitting direction so as to be higher than the front end side.

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 feet of a right-handed player. In the case of Figure 8, the left and right shoes are in a normal stance along the ground. This is a conventional case, and FIG. 9 is an example of the present invention, which shows a case where the right foot stands at an angle α with respect to the ground. Assume that the weight on the player's right foot is W. In the case of horizontal stance to the ground in Figure 8,
While the weight W is applied perpendicular to the ground, in the case of Figure 9, as shown in Figure 10, it is perpendicular to the plane that has an angle of α to the ground, that is, the X-X'' plane. Therefore, the weight W is perpendicular to the plane x-x' at an angle of α with respect to Figure 8. Therefore, in the case of Figure 9, that is, if only the right foot has an angle of α, the weight W is W minutes will be generated due to the movement of the weight created by the angle α applied to the left foot.In other words, the force generated from the right foot to the left foot of this ΔW, as explained in Figures 1 to 7, is generally When a player makes a backswing to hit the ball, the player's body moves from the ideal swing to the right side.
This is offset by the force △W in the opposite direction corresponding to the weight shifting table, and the more ideal swing shown in Figure 1 can be easily achieved in the situation shown in Figure 9 without causing the player's body to sway. It is possible to make it happen. Specific examples of inclined holding portions that actually realize the situation shown in FIG. 9 of the present invention are shown in FIGS. 12 to 15. The same will be said below, or in this embodiment, a golf shoe for the right foot of a right-handed player will be described. The golf shoe is a schematic diagram seen from the heel side.

FIG. 13 shows the bottom of a normal golf shoe 1. Figure 13 shows spikes 3.3 on the right row of the sole of the right shoe. .

, is formed to be higher by △h than the spikes 3" and 3°00. on the left row. When wearing this, the right foot will be inclined inward by △h. The shape of this spike 3 is the conventional one. As shown in the figure, one side of the seat is equipped with an insert pin that connects to a screw hole in the sole, and the other side is equipped with a tapered pin. It is also possible to have a structure in which washers are provided on both sides of the pins. Fig. 13 shows that the material of the bottom part 2, that is, the thickness of the rubber or leather, is changed from the beginning by Δh on the right side and is gradually made thicker. The slanted bottom part 2'' is glued or sewn onto the flat bottom part.

Figure 14 shows spikes 3.381. on the rear side of the bottom 2 of a regular golf shoe. At this position, a clamping part 4 made of another material such as rubber, leather, metal, etc. and having a thickness of Δh is additionally inserted between the bottom part 2 and the spikes 3.3. The clamping part 4 may be glued to the bottom part 2 or spikes 3.301. The bottom 2
It may also be clamped by screwing into. FIG. 16 shows a case where a rug 5 having a slope of thickness Δh, which is gradually thickened toward the right, is inserted inside a normal shoe, and thereby the same effect of the present invention can be produced. The above Δh can be used in the range of 5 to 401 mm, or preferably in the range of 10 to 25 mm.

F6 Functions and Effects of the Invention According to the present invention as described above, an inclination holding portion that holds the rear end side of the shoe on the rear foot side in the ball hitting direction so as to be higher than the front end side is provided, and an actual golf shoe can be used. By providing the structure of the back of the golf ball, especially the sole of the right foot for right-handed golf players, and the sole of the left foot for left-handed golf players, the swaying state during the backswing can be improved. By reducing the amount of force in the opposite direction corresponding to the movement of the weight, it eliminates sway, making the swing significantly more accurate, and increasing the flight distance of the ball as shown in Figures 1 to 5, and as shown in Figure 6. By modifying the swing conditions as described above, it is possible to significantly improve the directionality by suppressing slices, hooks, etc. in the target direction.

In addition, the present invention is applicable not only to the right shoe for right-handed players, but also to changing the thickness and angle of the soles of both feet in the same direction.
It enhances similar effects and produces effective results.
