JP7111379B2 - Swing practice equipment for fast-twitch training to increase flight distance in golf - Google Patents

Description

The present invention aims to train the fast-twitch muscles to increase the flight distance. It is a golf practice equipment that enables adjustment of the center-of-gravity distance, center-of-gravity depth, and center-of-gravity angle so as to swing.

Conventionally, practice equipment for practice swings in golf is often as heavy as 500g to 900g. There was no choice but to swing the swinging practice equipment upside down, or to swing a stick-shaped object.

For example, in Patent Document 1, a golf swing training device in which a one-side grip is provided on one end side of a shaft and the other-side grip is provided on the other end side of the shaft, the one-side grip is included and the grip is When the provided part is one side grip, the other side grip is included, and the part where the grip is provided is the other side grip, the one side grip is adjusted to be heavier than the other side grip, The frequency when one side grip is vibrated with the other side grip portion fixed is defined as "F1 (cpm)", and the frequency when the other side grip is vibrated with the one side grip portion fixed is defined as " When F2 (cpm)", a golf swing training device is disclosed, which is characterized in that it is adjusted so that "F1 < F2" and "F1 = 90 cpm to 220 cpm".

If the golf swing practice device described in Patent Document 1 is used, when swinging with the other side grip as the tip and holding the one side grip, the tip is light, so you can feel the weight at high speed without feeling the weight. It is said that it is possible to perform a swing with feeling.

However, the golf swing training device of Patent Document 1 is a stick-shaped object having the center of gravity at the tip of the stick, and cannot provide the center-of-gravity distance, the center-of-gravity depth, and the center-of-gravity angle, which are the characteristics of golf clubs. It was easy to learn a swing different from the swing, and there was a concern that it would adversely affect the actual shot.

Accordingly, the present invention has been made to deal with the above problem, and the problem to be solved is to provide a golf swing training device that has the same characteristics as a golf club while training the fast muscles to increase the swing speed. I have to do it.

In order to achieve the above object, the present invention, as a result of intensive research on the shape, structure, material, etc. of a golf swing training device, has been developed by attaching a head to the tip of a shaft to which a grip is attached, from the tip of the shaft to the toe side of the head. The center of gravity can be set at the center of the golf club, the center of gravity angle, the distance of the center of gravity, and the depth of the center of gravity, which are the characteristics of the golf club, can be realized.

In order to solve the above problems, the present invention
A head body fixed to the tip of a shaft, a grip provided on the outer periphery of the shaft opposite to the head, a weight member provided on the side surface of the head, and the weight member provided on the weight member. To provide a golf swing practice device characterized by comprising a weight that can move in a direction perpendicular to the shaft from one end to the other end of the

In the golf swing practice device of the present invention,
Characterized by a total weight of 150g to 250g

In the golf swing practice device of the present invention,
By attaching the weight member and the weight to the head, the distance from the extension of the shaft to the position of the center of gravity turned on the face surface, or from the extension of the shaft to the actual center of gravity in the air. Center of gravity distance, which is the distance of , Center of gravity depth, which is the distance from the position of the center of gravity turned on the face surface to the actual position of the center of gravity in the hollow, and the angle between the extension of the shaft and the actual position of the center of gravity in the hollow A certain center of gravity angle can be created, and by moving the weight, the center of gravity distance, the depth of the center of gravity, and the center of gravity angle of the head can be adjusted.

In the golf swing training device of the present invention, the total weight of the golf swing training device can be reduced to 150 g to 250 g by making the head of wood, for example, and the swing speed can be increased by training fast muscles by swinging quickly. I can.

By providing the head with, for example, a bolt as the weight member and providing, for example, a nut as the weight, it is possible to adjust the center-of-gravity distance, the center-of-gravity depth, and the center-of-gravity angle. As a result, it is possible to adjust the center-of-gravity distance, center-of-gravity depth, and center-of-gravity angle to be the same as those of golf clubs that are usually used, thereby avoiding adverse effects on the golf swing.

With the golf swing training device of the present invention having the structure described above, it is possible to train the fast muscles for increasing the swing speed without impairing the normal golf swing.

1 is a front view of the present invention; FIG. It is a right side view of a head. FIG. 4 is an exploded front view of the head, shaft and bolt; It is the front view which turned the position of the center of gravity to the face surface. It is a plan view in which the center of gravity distance is turned to the actual position in midair and the face surface. It is the top view which looked at the center-of-gravity depth. It is the top view which looked at the center-of-gravity angle from the upper part.

FIG. 1 is a front view showing a golf swing training device that is an embodiment of the present invention, FIG. 2 is a right side view of the head of the golf swing training device of the present invention, and FIG. 3 is a shaft and head of the golf swing training device of the present invention. , and an exploded front view of the bolt.

As shown in FIG. 1, the golf swing training device of this embodiment includes a head 1 attached to the tip of a shaft 2 and a grip 3 provided on the other end side of the shaft 2. As shown in FIG.

Further, the head 1 is provided with a bolt 4 provided on the side surface, a movable nut 5 provided on the bolt 4, and a nut fixing packing 6. - 特許庁
