Golf clubs and shafts

Abstract

This invention provides a golf club and its shaft. The golf club utilizes a movable weight mechanism installed within the shaft. During a high-speed swing, the centrifugal force generated drives the weight within this mechanism to move instantaneously and at high speed along the shaft towards the clubhead. This causes the weight to violently impact the clubhead, generating a strong impact force feedback and shifting the club's center of gravity. This strong feedback and shift in the club's center of gravity, even with a very light weight, allows the swinger (even a beginner) to easily feel and adjust their body posture, grip strength, and power release techniques. This achieves the effects of improving balance control, rapid awareness, swing technique adjustment, and refining shot technique during the swing.

Claims

1. A golf club, said golf club comprising at least: A shaft, handle, and head, characterized in that: the shaft comprises: a body and a movable counterweight mechanism assembled within the body; the body is a hollow elongated tube with two ends, one end connected to the handle and the other end connected to the head; the movable counterweight mechanism comprises at least a magnetic body and a metal counterweight; the magnetic body is fixed within the body and positioned between the handle and the head; the metal counterweight is magnetically attracted to the magnetic body. With the above-described structure, before swinging, we align the clubhead with the ball and begin to lift the shaft to the optimal hitting position. At this point, the metal weight is magnetically attracted to the magnetic body. Once the swing begins, the high-speed centrifugal force generated by the downward swing causes the metal weight to be quickly thrown off and move at high speed along the inside of the shaft towards the clubhead. It then violently impacts the inner wall of the clubhead, instantly generating a high-speed impact force feedback and shifting the shaft's center of gravity. Through this strong feedback and shift in the shaft's center of gravity, we can easily feel and adjust our body posture, grip strength, and techniques for releasing power appropriately during the swing, thus correctly striking the ball to achieve the optimal hitting point.

2. The golf club as described in claim 1, wherein the movable weight mechanism further includes a stop body, the stop body being fixed within the body and positioned between the handle and the clubhead; once the player swings the club, utilizing the high-speed centrifugal force generated by the downward rapid swing, the metal weight is quickly thrown off and moves at high speed along the inside of the shaft towards the clubhead, violently impacting the stop body to instantly generate a high-speed impact force feedback feel and a shift in the shaft's center of gravity. Through this strong feedback feel and the shift in the shaft's center of gravity, even with a very light weight, the player can easily feel the shaft's feedback upon impact, which can help adjust the body posture during the swing, control the grip strength of the handle, and the techniques for appropriately releasing power, thereby correctly striking the ball to achieve the optimal hitting point.

3. The golf club as described in claim 1, further comprising an adapter connector, one end of which is assembled to the other end of the body relative to the handle, the other end of which is connected to the clubhead, and the adapter connector having an inner wall; once the club is swung on the course, utilizing the high-speed centrifugal force generated by the downward rapid swing, the metal weight is quickly thrown off and moves at high speed along the inside of the shaft towards the adapter connector, violently impacting the inner wall of the adapter connector, instantly generating a high-speed impact force feedback feel and a shift in the center of gravity of the shaft. Through this strong feedback feel and the shift in the center of gravity of the shaft, even with a very light weight, we can easily feel the shaft feel feedback during the impact, which can help adjust the body posture during the swing, control the grip strength of the handle, and the techniques of how to properly release power, thereby correctly hitting the ball to achieve the optimal hitting point.

4. As described in claim 1, the movable weight mechanism further includes a stop and an adapter with an inner wall, one end of which is assembled to the other end of the body relative to the handle, and the other end of which is connected to the clubhead; the stop is fixed within the body and positioned between the handle and the adapter; when swinging the club, the high-speed centrifugal force generated by the downward swing causes the metal weight to be quickly thrown away and move at high speed along the inside of the shaft towards the clubhead, violently impacting the stop, instantly generating a high-speed impact force feedback and a shift in the shaft's center of gravity. Through this strong feedback and shift in the shaft's center of gravity, even with a very light weight, one can easily feel the impact feedback, which can help adjust body posture during the swing, control grip strength, and techniques for releasing power appropriately, thereby correctly hitting the ball to achieve the optimal hitting point.

5. The golf club as claimed in claim 1, wherein the magnetic body is a hard magnet and is integrally fixed to the body via a fixture assembly.
