Abstract

PURPOSE:To prevent sways during backswings and to realize exact swing, by providing both golf shoes with a tilt retainer to keep the heel in the shooting direction higher than the toe, and by making the tilt of the backward shoe in the shooting direction larger than that of the forward one. CONSTITUTION:Since the right-side spike 3 of the right-shoe's sole is formed DELTAh higher than the left-side spike 3', the right foot tilts inward by DELTAh upon putting the shoe on. The material of the sole 2, namely, rubber or leather is thickened by a tilt of DELTAh on the right side. Alternatively, a DELTAh-thick insert 4 made of another material such as rubber, leather, metal, or the like is interposed between the sole 2 and the spike 3 at the position of the rear-side spike 3 of the shoe' s sole 2. A preferable thickness DELTAh is 10-25mm. On the other hand, the left-side golf shoe should be based on the right-side one except that the height is lowered.

Description

DETAILED DESCRIPTION OF THE INVENTION A. Field of Industrial Application The present invention relates to a golf course, and is designed to improve and improve it so that general golf players can swing more accurately and reliably to the ball when playing golf. It is related to the Purfuseuse that I went to.

BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 shows the trajectory of a typical ideal golf swing, the principle of which 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,
Movement including the body's axis, ie, the body sway phenomenon, generally occurs. In the ideal swing shown in Figure 1, the swing starts from point rSJ, descends to rSJ 4rT, 1l-rHJ with radius of rotation R, and the club is pushed out horizontally by ΔX, and the apogee of club rotation becomes R + ΔX. Move to rFJ. On the other hand, when the body sways as shown in Figure 2, the points rTJ and rHJ move by ΔX in the pax ink, and the swing starts from point rSJ and starts at point rsJ → rTJ−rH.
' J →rHJ-rF'', the apogee of club rotation becomes smaller as R-ΔX°, and compared to the ideal swing, the distance beyond that point is (R-(Δχ+ΔX°)), only the movement of the body relative to ΔX The time to actually hit the ball is delayed, and when you hit the ball, the club face is at a point as high as ΔY as shown in the second figure, and at an angle of θ as shown in the fourth figure, which is an addition to the loft angle of the club. The situation becomes (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 It has an angle of θ, which becomes a force F', and ΔF
The force becomes smaller. That is, F>F' and F=Δ
The relationship F+F' holds true. This shows that, as shown in Figure 5, compared to the ideal flight distance diagram (a), the flight distance is shorter as shown in b). This relationship (C
) shows the relationship between the player's foot position and the position when holding the ball, Figure 6 shows the relationship rHJ between the ideal stance and the position of the ball, and Figure 7 shows the relationship between the player's foot position and the position when holding the ball. When the body moves towards the right foot by ΔR,
The positional relationships of rSJ, rHJ, and rH' J are shown in detail.

C. Problems that need to be solved As mentioned above, when an ordinary player makes a backswing to hit the ball, the ideal swing situation will result in a 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 great, and the direction in which the ball is launched is not determined.

20 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. For this reason, when swaying, the end of the foot in one direction of the sway is held high in order to counteract it by applying a force in the opposite direction corresponding to the movement of the body weight and prevent the sway. We are proposing a golf shoe that allows you to play golf.In addition, the left and right shoes are provided with an inclined holding part that holds the rear end side in the ball hitting direction higher than the front end side, and the slope of the shoe on the rear side in the ball hitting direction is changed from the slope of the shoe on the front side in the ball hitting direction. It is characterized by being larger than shoes.

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

Figures 8 and 9 show the foot position of a right-handed player,
Show different foot situations with that angle. In the case of Figure 8, the left and right shoes are taken in a normal stance along the ground, and in the case of Figure 9, the right foot is taken in a stance with an angle of α to the ground. , and 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 applied at an angle of α to the ground as shown in Figure 10. , i.e. x-
Since it is perpendicular to the x' plane, the weight W is α for Figure 8.
It is perpendicular to the plane x-x' with an angle of . 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 will occur from the right foot to the left foot. In other words, as explained in Figures 1 to 7, if the force generated from the right foot to the left foot of ΔW is The situation where the player moves to the right side from a normal swing is offset by the force △W in the opposite direction, which corresponds to the weight shift.
The more ideal swing shown in Figure 1 can be easily achieved in the situation shown in Figure 9 without the player's body swaying.

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 in order to maintain bad momentum, and at the same time, it is expected that there will be a countervailing force that synergizes with the counterbalancing force of ΔW. And there are three forms:

Among these, the effect is greatest when α>α°.

Therefore, The maximum effect can be ensured when .

Specific examples of the inclined holding part that actually realizes the situation shown in FIG. 10 of the present invention are shown in FIGS. 13 to 17, and the same applies hereafter. I will explain about the side golf shoes. Golf shoes for the left foot should be similar to those for the right foot in order to reduce the height. The golf shoe is a schematic diagram seen from the heel side. Figure 13 shows the bottom of a normal golf shoe. Figure 13 shows the right row of spikes 3.300. is made higher by Δh than the spikes 3°, 3', . . . in the left row. When wearing this, the right foot will be inclined inward by Δh. The shape of this spike 3 is similar to the conventional type, with a butterfly pin on one side of the washer that connects to a screw hole in the sole, and a tapered pin on the other side, but the washer is thicker. Figure 14 shows the material of the bottom part 2, that is, the material of the bottom part 2.
The thickness of the rubber or leather is changed from the beginning by Δh on the right side and gradually increases in thickness. Figure 13 shows spikes 3.300. At the position of bottom 2 and spike 3
．． A clamping part 4 made of a different material such as rubber, leather, or metal flexure and having a thickness of Δh is additionally inserted between the openings 3 and 3. The clamping part 4 may be glued to the bottom part 2 or spikes 3.381. Fig. 16 shows a case where a rug 5 having a thickness of Δh, which is gradually thickened on the right side, is inserted into the inside of an ordinary shoe. Similar effects of the present invention can be produced.

The above Δh can be from 5 to 40, but from 10 to 25
It is preferred or preferred.

Functions and Effects of the Invention According to the present invention as described above, the left and right shoes are provided with inclined holding portions that hold the rear end side in the ball hitting direction at a higher height than the curved end side, and the shoes on the rear side in the ball hitting direction The slope of the shoe was made larger than that of the front shoe, so the structure of the sole of an actual golf shoe, especially for a right-handed golf player, the sole of the right foot is larger than that of the left foot, and for a left-handed golf player, the sole of the right foot is larger than that of the left foot. By making the sole of the left foot have a larger angle than that of the right foot, the sway during the backswing is reduced by the force in the opposite direction corresponding to the movement of the body weight, thereby significantly eliminating the sway. By making the swing more 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, slices and hooks in the target direction were suppressed. Directionality can be significantly improved.

In addition, the present invention provides a slope for not only the right shoe of a right-handed player but also the left foot, changing the slope of the soles of both feet in the same direction,
By giving a stronger angle to the shoes on the rear side of the ball, the effect is further enhanced and more effective results are produced.
