Abstract

1. Technology Field

The golf club is divided into three parts: the grip part, the shaft part, and the head part.

The present invention relates to a shaft which is one of the components of a golf club.

2. Technical Challenge

Conventional golf recruitment shaft is made of a thin thin body of a straight line, so when a driver shots a golf ball with a strong force, a large shock is immediately transferred to the wrist and the human body, which causes a large impact on the wrist injury and the human body, thereby causing a strain on the body. Was added.

Therefore, the present invention is intended to improve the structure of the shape and shape of the golf shaft to minimize the impact that is transferred directly to the wrist and body when the driver shot the ball.

3. Summary of solution

As a method for minimizing the shock wave that a large impact is transmitted to the wrist part and the human body when hitting the ball, the present invention has a large number of (1-100) concave nodes (2), such as a node in bamboo, on the outer peripheral surface of the golf shaft. Or, to provide a golf recruiting shaft made of a structure that constitutes a convex node (3) horizontally or inclined continuously.

4. Uses

The present invention relates to a golf recruiting shaft, and more particularly, to a golf recruiting shaft that has improved impact mitigation.

The golf club is divided into three parts: the grip, the shaft, and the head that hits the ball. The shaft is made of a thin tube made of metal or fiber reinforced resin. Recently, glass metal has been developed to promote club development for shaft use.

Golf is a game (exercise) in which the result of a game can be determined depending on how far the golf ball should be sent to the correct position at a time. Therefore, everybody makes a driver shot with a strong force. The strong shock is transmitted to the wrist and the human body directly through the shaft and the grip without filtration, which causes a great impact on the human body.

Looking at the golf adoption shaft in the case up to now, rather than the development of technology for the impact prevention and mitigation of the above impact was in the situation that the weight of the development of the material of the shaft itself. Therefore, the present invention is to solve the conventional technology and problems in order to be able to mitigate and disperse the impact through changes in the shape and structure of the shaft.

Looking at this in detail by the accompanying drawings as follows.

Golf employing shaft 1 of the present invention is a regular or irregular shape of a plurality of concave nodes (2), or convex (3) consisting of a shape and shape suitable for the outer peripheral surface, such as a bark in bamboo To provide a shaft (1) formed in a continuous horizontal or inclined structure.

When the operation effect of the golf recruitment shaft 1 of the present invention configured as described above is seen, the concave node in which the width of the groove of the node, the depth of the groove of the node, and the distance between the node and the mi is appropriately configured on the outer circumferential surface of the shaft 1 (2) Or, by forming a node of the shape of the convex node (3), unlike the shaft consisting of a straight line, the strong shock wave generated when the driver shot the ball with a strong force in a straight line in the straight form And waves in the form of waves that are not transmitted to the body Because the shock wave is transmitted to the body, the speed at which the shock wave is transmitted to the body becomes slow, and the shock wave is dispersed and reduced in the middle while passing through the wave-shaped wavelength, so that the shock wave transmitted to the human body decreases. You will get reduced results.

In addition, by mounting an elastic member such as rubber on the inner surface of the groove of the concave section 2 provided on the outer circumferential surface of the shaft 1 of the present invention (not shown in the drawing), the shock absorption and relaxation action can be further doubled. You will get the results you can.

Of course, even in the case of the existing shaft of the metal takes the form of a section called a step, but this is fundamentally different from the shape of the concave section 2 and the convex section 3 of the present invention.

That is, in the conventional metal shaft, the shape of the node is a stepped node ( It is taking form.

Unexplained symbol w. Is the width of the groove of the node, d. Is the depth of the groove of the node, L is the distance between the node and the node c. Is the angle of inclination of the node.

If the concave node 2, or the convex node 3 of the present invention is configured as described above when using the golf recruiting shaft 1 is formed;

Unlike the conventional straight shaft, the manufacturing process is not complicated, difficult, or more expensive. Rather, the concave or convex nodes 2 and 3 are horizontally or inclined to the outer peripheral surface of the shaft 1 continuously. By forming it, it is possible to obtain more elastic effect, and to reduce the impact on the wrist and the human body due to the large shock wave generated when the driver shots the ball with a strong force, and to obtain the impact relaxation and dispersion effect as much as possible. It is a useful design with several advantages that can contribute to the sales and export growth due to the differentiation and high quality of the product.
