Golf club head
A golf club head includes a half-circle metal ring that extends outwards from the rear surface of the head. The weight of the half-circle metal ring is adjustable according to the weight of the head. The half-circle metal ring can be a solid ring or a hollow tube. By change in diameter of the cross section of the half-circle metal ring, the center of gravity moves back in the club head and the center-of-gravity angle as well as the depth of center-of-gravity are both increased so as to achieve greater hitting efficiency.
The present invention relates to a golf club head, especially to a head with a half-circle metal ring with certain weight being fixed on the rear surface. The half-circle metal ring extends outwards, perpendicular to the rear surface of the head so as to make the center of gravity of the head move back, increase the center-of-gravity angle and the depth of center-of-gravity of the head.
For golf clubs, especially to drivers, the design of the head directly affects the hitting efficiency. An optimum design of golf club head is a golf club head with larger angle of center-of-gravity, a longer depth of center-of-gravity, or an enlarged sweet spot. The design of the present inventions complies with the above demands.
SUMMARY OF THE INVENTIONTherefore, it is a primary object of the present invention to provide a golf club head with a half-circle metal ring fixed on the rear surface. The half-circle metal ring protrudes outwards and locates perpendicular to the read side of the head. The weight of the half-circle metal ring is adjustable in accordance with the weight of the head. For example, the half-circle metal ring can be hollow tube or a solid ring that is changeable in diameter. Thus the center of gravity of the head moves back, the center-of-gravity angle is increased, and the depth of center-of-gravity is increased so that the hitting efficiency of the head is improved.
It is another object of the present invention to provide a golf club head with holes on the plane for fixing the half-circle metal ring. During the manufacturing process of the head, insert two screws and lock nuts into the holes on the rear surface and turn the screw until the nut is firmly seated so as to make the half-circle metal ring be fixed on the rear surface of the head easily.
BRIEF DESCRIPTION OF THE DRAWINGSThe structure and the technical means adopted by the present invention to achieve the above and other objects can be best understood by referring to the following detailed description of the preferred embodiments and the accompanying drawings, wherein
Refer to
Furthermore, the weight of the half-circle metal ring 20 is adjustable in accordance with the weight of the main body 10. For example, the half-circle metal ring 20 is a hollow tube or a solid ring. Or by change in the diameter of the cross section of the half-circle metal ring 20, the weight can be adjusted so as to create more effective main body 10.
Refer to
The main body 10 is made by various processing methods.
Refer to
Additional advantages and modifications will readily occur to those skilled in the art. Therefore, the invention in its
