Description

Cu alloy golf club head and it's consent, shaft}

The metal material to be used as the head part of the golf putter club should have a certain hardness and strength to ensure the repulsion of the ball when impacted with the golf ball. The hardness and strength of the material were not suitable, and gold coating on strong materials such as titanium could not be continued due to the friction and impact with the ground or turf, and frequent discoloration. The production of gold golf club heads that maintain the hardness and strength as golf club heads, such as wear or wear, has been recognized as technically impossible. In the case of conventional golf putters, the overall design of the head is horizontally centered on the hitting surface of the ball. That the swing stability is not maintained In addition, when the game was played on the slope, the swing posture of the player and the swing progress direction of the putter did not get good results. In particular, in the putting, which is the most important part of the game, the actual putter does not solve the problems that are not technically difficult for general players, such as the slope of the terrain and the texture of the grass, and the number of strokes is increased. The development of the equipment was sluggish compared to the importance of putting, which determines the performance of the company. In particular, in the case of mid-level athletes who exceed the standard strokes by about 20 strokes, unless they are particularly strong in terms of strength and grip, they must use shafts made of carbon graphite with a certain flex, and generally manufacture monolithic mandrel. In the case of the construction shaft, there was a technical limitation that inevitably there was a distortion in the case of bending.

The present invention solves the above problems Al 4.0%, Si 0.4%, Ag 1.5%, Co 0.3%, Fe 0.8%, Ma 1.2%, Zn 0.2%, Be 0.3%, Ni 3.0%, Cr 0.8% Participate in copper to obtain mechanical properties of 95Kg / mm3 tensile strength, 4% elongation and 260HV10Kg hardness to solve the problems of hardness and strength that are not suitable as golf club materials.

The wedge-shaped golf putter head manufactured by the precision casting method of the material is installed with two shaft mounting holes and coupled with the shaft through a dedicated outlet to increase the efficiency of torque correction.

The surface of the wedge-shaped putter head is curved with a 70mm pie to maintain a constant trajectory even if the surface is hit by the ball under any swing posture or terrain.

In the design of the wedge-shaped putter head, the longitudinal axis in the direction perpendicular to the hitting surface is designed to overcome the swing instability which is a problem of the conventional transverse design putter head.

In the case of iron sets 3-9, pitching wedges and sand wedges, the sweet spot recognition plate is installed based on the horizontal axis design to increase the impact of the hitting.

In the case of the flat putter head, a blow plate made of natural rubber is inserted to prolong the contact time with the ball at the time of batting, thereby significantly increasing the fine batting control ability.

Two adjustable gears are installed on the rotating shaft to ensure maneuverability of 360 degrees on the vertical axis and 320 degrees on the horizontal axis so that any lie or loft angle can be adjusted according to the objective conditions of the stadium and the subjective needs of the competitor. Designed to

In the case of a combined shaft, when manufacturing a golf club shaft with a vibration cycle of 220 cpm or less using a prepreg with a tensile strength of 240 kg / m2 or less, it was technically impossible to adjust the torque to 3.5 or less by the conventional monolithic mandrel manufacturing method. This combination type shaft is designed to firmly combine the details, so that the torque can be adjusted to 3.0 or less in the vibration cycle of 200cpm to stabilize the ball's flight direction at the time of hitting.
