Abstract
A top crown of a golf club head has a crown body and multiple reinforcing ribs formed on at least one of an inner surface and an outer surface of the crown body. The reinforcing ribs are arranged as a mesh including multiple grids. The top crown can be hot forged to form the meshed reinforcing ribs. With the meshed reinforcing ribs on the top crown, a thickness of the crown body of the top crown can be appropriately reduced and the strength of the crown body is enhanced by the reinforcing ribs. Accordingly, elasticity of the top crown of the golf club head is increased and the top crown has low center of gravity.
Description
- 1. Field of the Invention
- The present invention relates to a top crown of a golf club head, especially to a top crown of a golf club head that has light weight and low center of gravity.
- 2. Description of the Prior Art(s)
- Since golf wood club heads have very specific shapes, the golf wood club heads are difficult to be formed as one piece. Therefore, the golf wood club head is usually manufactured by attaching four pieces, i.e. a top crown, a base, a strike face, and a hosel. For a conventional top crown made of titanium alloy, multiple cavities are formed on an inner surface of the conventional top crown by acidic etching to reduce weight and enhance elasticity of the golf club head. Thus, the conventional top crown of the golf club head, which has an average thickness of 1 millimeter (mm), has some portions with thickness of 0.5 mm to 0.9 mm.
- When the cavities on the conventional titanium alloy top crown are formed by acidic etching, tapes should be manually adhered on the surface of the conventional titanium alloy top crown to cover portions that do not need acidic etching. Then, hydrofluoric acid is applied to other portions of the conventional titanium alloy top crown that are not covered by the tapes to form the cavities. Afterwards, the conventional top crown of the golf club head is cleaned and is formed into a predetermined shape.
- However, during the acidic etching process to reduce the weight of the conventional top crown of the golf club head, it takes time and efforts to adhere the tapes on the portions of the conventional top crown that do not need acidic etching. Moreover, the hydrofluoric acid used during the acidic etching is toxic and pollutes the environment. Hydrogen ion in the hydrofluoric acid infiltrates into the titanium alloy easily to embrittle the conventional top crown. Thus, strength of the conventional top crown is weakened and the conventional top crown breaks easily. On the other hand, during the acidic etching process to reduce the weight of the conventional titanium alloy top crown, time for acidic etching and concentration of the hydrofluoric acid influence the thickness of the conventional top crown such that the thickness of the top crown is hard to be kept under control as desired. In addition, the conventional top crown being acidic etched is still too thick, so the elasticity the conventional top crown is not good enough for striking golf balls far. Furthermore, shapes of the cavities formed by the acidic etching are irregular and cannot be molded and controlled according to a required striking performance of the golf club head.
- To overcome the shortcomings, the present invention provides a top crown of a golf club head to mitigate or obviate the aforementioned problems.
- The main objective of the present invention is to provide a top crown of a golf club head.
- The top crown has a crown body and multiple reinforcing ribs. The crown body has an inner surface and an outer surface. The reinforcing ribs are formed on at least one of the inner and outer surfaces of the crown body. The reinforcing ribs are arranged as a mesh including multiple grids.
- In the above-mentioned top crown, the reinforcing ribs of the top crown are formed on the inner surface of the crown body.
- In the above-mentioned top crown, the reinforcing ribs of the top crown are formed on the outer surface of the crown body.
- In the above-mentioned top crown, the reinforcing ribs of the top crown are formed on the inner surface and the outer surface of the crown body.
- In the above-mentioned top crown, the top crown is formed by hot processing.
- In the above-mentioned top crown, a thickness of the crown body is 0.2 millimeter (mm) to 1.0 mm, and a thickness of each of the reinforcing ribs is 0.1 mm to 1.8 mm.
- In the above-mentioned top crown, each of the grids of the mesh of the reinforcing ribs is circular, elliptical, or polygonal.
- In the above-mentioned top crown, each of the grids of the mesh of the reinforcing ribs is triangular, quadrilateral, or hexagonal.
- The top crown can be hot forged to form the meshed reinforcing ribs. With the meshed reinforcing ribs on the top crown, a thickness of the crown body of the top crown can be appropriately reduced and the strength of the crown body is enhanced by the reinforcing ribs. Accordingly, elasticity of the top crown of the golf club head is increased and the top crown has low center of gravity.
- Other objectives, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
-

FIG. 2 is a cross-sectional side view of the top crown inFIG. 1 ; -
FIG. 3 is an operational exploded perspective view of the top crown inFIG. 1 , showing the top crown is attached to a base, a strike face, and a hosel to form the golf club head; -
FIG. 4 is an operational cross-sectional side view of the top crown inFIG. 1 , showing the top crown is attached to the base, the strike face, and the hosel to form the golf club head; -
FIG. 5 is a perspective view of a second embodiment of a top crown of a golf club head in accordance with the present invention; -
FIG. 6 is a front view of a third embodiment of a top crown of a golf club head in accordance with the present invention; -
FIG. 7 is a front view of a fourth embodiment of a top crown of a golf club head in accordance with the present invention; -
FIG. 8 is a front view of a fifth embodiment of a top crown of a golf club head in accordance with the present invention; and -
FIG. 9 is an operational perspective view of the golf club head having the top crown of the present invention. - With reference to
FIG. 1 , atop crown 1 of a golf club head in accordance with the present invention is hot forged and has acrown body 10 and multiple reinforcingribs 20. - With further reference to
FIG. 2 , thecrown body 10 is made of titanium alloy, and has aninner surface 11 and anouter surface 12. A thickness d1 of thecrown body 10 is 0.2 millimeter (mm) to 1.0 mm. The reinforcingribs 20 are foamed on at least one of the inner andouter surfaces crown body 10 and are arranged as a mesh. The mesh includesmultiple grids 21. Each of thegrids 21 of the mesh may be circular, elliptical, or polygonal. - With further reference to
FIGS. 3 and 4 , thetop crown 1 is welded with abase 2, astrike face 3, and ahosel 4 to form the golf club head. Then the golf club head is surface treated and thehosel 4 is attached securely to a shaft to accomplish the golf club.
