Description

Technical Field

[0001] The utility model relates to the technical field of sports goods, in particular to a spiral golf club shaft and a golf club including the shaft.

Background Art

[0002] In the sport of golf, the golf club is one of the important factors affecting the player's hitting effect. In the production and manufacturing process of traditional steel golf club shafts, there will be a longitudinal weld extending from the top end of the shaft to the bottom end. The hardness of the weld is higher than other positions, just like a ridge line, which is called "Shaft spine" in the golf equipment industry. As shown in Figure 6 Mark 5, it plays a role of support and strengthening in the shaft.

[0003] However, the existence of an obvious ridge line will bring some potential problems. For example, if the relative angle between the ridge line and the golf club head is not paid attention to during the assembly of the golf club shaft and the club head, resulting in a mismatch between the angle of the ridge line and the club head, it will cause the club face to twist or deflect during hitting, thereby affecting the flight direction and rotation characteristics of the golf ball when the player hits the ball, leading to the player's confusion about whether it is a problem with the hitting action or the golf club, thus affecting the player's training and competition performance.

Content of the Utility Model

[0004] The purpose of the utility model is to provide a spiral golf club shaft to solve the problem that the club face twists or deflects during hitting due to the obvious ridge line existing in the golf club shaft at present.

[0006] A spiral golf club shaft, one end of the shaft is assembled with a grip, the other end is assembled with a club head, and a threaded portion for adjusting the ridge line is provided on the shaft. The threaded portion is formed by spiral welding of metal sheets, and the threaded portion is located on the shaft and extends spirally along the axial direction.

[0007] For the spiral golf club shaft as described above, the thickness c of the threaded portion is less than or equal to or greater than the thickness a of the shaft.

[0008] For the spiral golf club shaft as described above, the ratio of the width b of the threaded portion to the thickness a of the shaft is (0.8 - 5):1.

[0009] For the spiral golf club shaft as described above, the spiral angle β of the threaded portion is 45 - 75°.

[0010] For the spiral golf club shaft as described above, the material of the threaded portion and the material of the shaft are the same or multiple materials.
