DESCRIPTION OF THE PREFERRED EMBODIMENTS The invention of the present application is a golf practice tool using a short golf club for practice, in which a golf ball is provided at the tip of a 10-50 cm arm that extends substantially horizontally, The ball may be a golf ball itself or a pseudo golf ball. If the length of the arm is less than 10 cm, the possibility of accidentally hitting the axis during swinging increases. If the length of the arm is more than 50 cm, the golf ball rotates around the axis.

The other end enables the pseudo golf ball and the arm to rotate about the axis or integrally with the axis at the time of impact. For example, in order to rotate about the axis, Preferably, a cylindrical member is provided at the end of the arm. Further, the arm with the arm may be rotated, for example, the arm and the shaft may be integrated, and the shaft may be inserted into a cylindrical member to rotate.

When a cylindrical member is provided at the end of the arm, a shaft serving as a rotation center is provided in the tube, and a slight gap is provided between the tube and the shaft to facilitate rotation. doing. Further, a mechanism may be adopted in which a bearing or the like is attached to the cylindrical portion to reduce friction with the shaft and facilitate rotation.

The arm is preferably made of a plastic, an elastomer, a fiber reinforced resin, or a metal having a low specific gravity, for example, an aluminum alloy or a titanium alloy. One-piece molding is inexpensive and absorbs the impact during impact. The shaft serving as the center of rotation is preferably one that does not easily wear, and may be an amorphous material such as metal or ceramic.

It is preferable that the axis is inclined at 5 ° to 45 ° with respect to the vertical direction, because the hit golf ball can always be set at a position before hitting. If the inclination is less than 5 degrees, the golf ball may not return to the position before hitting.If the inclination is more than 45 degrees, the club head may swing upward during swing, making it easier to hit the arm. There is. Also, a rod-shaped object may extend from the stand to the ground in a substantially horizontal direction, and a shaft may be provided at the end thereof to attach an arm having a pseudo golf ball at one end. By doing so, after hitting the ball, the golf ball and the arm always return to the position of the lowest point after rotating about the axis, so that there is no trouble in setting the golf ball. The arm only needs to be rotatable, and the arm may be rotatable with respect to the axis, or the arm may be integral with the axis, and the arm and the axis may be rotatable. .

[0010] Furthermore, in this golf practice tool, by mounting a plurality of arms having a golf ball or a pseudo golf ball at one end in the up-down direction, it is easy to confirm the swing of the swing in the up-down direction. It may be. In particular, if three are attached, it will be easy to see which one is up or down. Further, it is more preferable to color-code each golf ball or pseudo golf ball, since a target golf ball can be determined during swing practice and swing practice can be performed.

The arm is fixed to a shaft so that the short club can be swung in a normal posture so that the arm does not come off when the ball is hit. The method of fixing is not particularly limited, but it is preferable to fix with screws.

[0012] The height of the golf ball of the training tool from the ground is preferably 50 cm to 100 cm, and the stand may have a height adjusting function so that the height can be adjusted. If it is less than 50 cm, the length of the short club must be increased, making it difficult to practice indoors. If the height is 100 cm or more, the height of the golf ball may be higher than the position of the hand.

[0013] It is necessary for the golf training device of the present invention to prevent falling when hitting a ball. For example, the width of the bottom surface of the stand is preferably 30% or more of the height of the golf ball. If the width of the stand is less than 30% of the height of the golf training equipment, the golf training equipment may fall down at impact.

The material of the stand is preferably the same or heavier as the main material used for the stand, compared to the main material used for the arm. In particular, it is preferable to attach a weight to the stand or make the lower part heavier so that the stand will not fall down.
