Benefits of technology

[0006] An object of the present invention is to provide a golf club head including a deformation portion in a sole portion, wherein maximum deformation occurs in the thinnest portion of the deformation portion, thereby enhancing the elastic effect and the hitting performance.
[0007] Another object of the present invention is to provide a golf club head including a sole portion with a deformation portion near the face portion for shifting the center of gravity of the overall golf club head rearward, allowing more flexible adjustment of the center of gravity of the golf club head.
[0008] A further object of the present invention is to provide a golf club head including a sole portion with a deformation portion, wherein the deformation portion has a plurality of recesses in a surface thereof to enhance the elastic effect and the hitting performance.

Problems solved by technology

Although the above-mentioned golf club head may enhance the elastic deforming effect of the sole portion and thus the hitting performance by providing a deformation portion without greatly altering the shape of the head, further improvement is not provided in the basic structure of the deformation portion.
The elastic effect is enhanced when the thickness of the deformation portion is small, yet the structural strength of the sole portion is adversely affected.

first embodiment

[0028] Referring to FIGS. 1 through 3, a golf club head 10 in accordance with the present invention comprises a face portion 11, a sole portion 12, a toe portion “a” and a heel portion “b”. In the illustrated embodiment, the golf club head is an iron club head made by casting, forging, or mechanical processing. The face portion 11 is disposed on a front face of the golf club head for hitting a golf ball. The sole portion 12 forms a lower portion of the golf club head.

[0029] The sole portion 12 comprises a deformation portion 13. In the illustrated embodiment, the deformation portion 13 is formed on an outer face of the sole portion 12 near the face portion 11, with an inner face of the sole portion 12 protruding upward toward a blade (not labeled) of the golf club head 10. The deformation portion 13 extends from the toe portion “a” to the heel portion “b” of the golf club head 10, providing a structure with enhanced elastic effect.

[0030] The deformation portion 13 comprises a defor...

second embodiment

[0034]FIG. 5 illustrates the invention. In this embodiment, the golf club head 10 is a head of a wood club or utility golf club. Similarly, the sole portion 12 comprises a deformation portion 13 near the face portion 11. The deformation portion 13 extends from the toe portion (not labeled) through the heel portion (not labeled) of the golf club head 10.

[0035] The deformation portion 13 comprises a deformation-starting section 131, a deformation-ending section 132, and a maximum deformation section 133 between the deformation-starting section 131 and the deformation-ending section 132. The thickness of the deformation-starting section 131 and the thickness of the deformation-ending section 132 decrease toward the maximum deformation section 133 so that the maximum deformation section 133 has the smallest thickness. Thus, the elastic deforming capability of the sole portion 12 of the golf club head 10 is increased without sacrificing the structural strength of the sole portion 12. The...

Abstract

A golf club head includes a face portion disposed on a front face of a golf club head for hitting a golf ball and a sole portion formed on a lower portion of the golf club head. The sole portion includes a recessed deformation portion. The deformation portion includes a deformation-starting section, a deformation-ending section, and a maximum deformation section between the deformation-starting section and the deformation-ending section. A thickness of the deformation-starting section and a thickness of the deformation-ending section decrease toward the maximum deformation section so that the maximum deformation section has the smallest thickness allowing elastic deformation, thereby increasing elastic deforming capability of the sole portion.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a golf club head. In particular, the present invention relates to a golf club head with an improved sole portion. [0003] 2. Description of Related Art [0004] U.S. Pat. No. 6,887,165 discloses a golf club including a face portion, a sole portion, and a crown portion. The face portion is disposed on a front face of a metallic golf club head and has a hitting surface for hitting a golf ball. The sole portion and the crown portion respectively form a lower portion and an upper portion of the metallic golf club head. A deformation portion is disposed on the sole portion and capable of elastic deformation when a golf ball is struck. The deformation portion comprises a protruding part which protrudes such that the sole portion is formed in an obtuse angle, in continuation with the hitting surface and the face portion in order to enhance an elastic effect. The protruding part has a first cor...
