Club head conducive to enhancement of resilience

Abstract

A club head conducive to enhancement of resilience includes a body and a panel. The body has a first front side and a first rear side. The panel is disposed on the first front side of the body. The panel has a second top edge, a second bottom edge, a second front side and a second rear side. The second front side is a ball-hitting surface. The second bottom edge extends toward the second rear side to form a wall portion. The wall portion partially sinks to a depth for defining a bending section facing the upper edge. As soon as the panel hits a ball, the bending section deforms and thereby generates bounce resilience.

Description

BACKGROUND OF THE INVENTION

1. Technical Field

The present disclosure relates to golf clubs and, more particularly, to a club head conducive to enhancement of ball-hitting resilience.

2. Description of Related Art

A conventional golf club is typically composed of a shaft and a club head. The club head is mainly composed of a body 1 and a panel 2, as shown in FIG. 1. From a structural perspective of commercially-available club heads, their panels are generally of two types: plate-shaped panels and cup-shaped panels. Referring to FIG. 1, the edge of the plate-shaped panel is coupled to the body and thus fixed thereto. The cup-shaped panel has the same edge as the plate-shaped panel. The edge of the cup-shaped panel extends to form an annular wall portion which surrounds the panel. The annular wall portion is coupled to the body. The plate-shaped panels and the cup-shaped panels each have a drawback, that is, providing additional bounce resilience during a ball-hitting process by deformation of the panel itself.

BRIEF SUMMARY OF THE INVENTION

It is an objective of the present disclosure to provide a club head conducive to enhancement of ball-hitting resilience of ball-hitting surface

In order to achieve the above and other objectives, the present disclosure provides a club head conducive to enhancement of resilience, comprising a body and a panel. The body has a first front side and a first rear side. The panel is disposed on the first front side of the body. The panel has a second top edge, a second bottom edge, a second front side and a second rear side. The second front side is a ball-hitting surface. The second bottom edge extends toward the second rear side to form a wall portion. The wall portion partially sinks to a depth for defining a bending section facing the upper edge. As soon as the panel hits a ball, the bending section deforms and thereby generates bounce resilience.

Referring to FIG. 2 through FIG. 7, a club head conducive to enhancement of resilience according to the first embodiment of the present disclosure comprises a body 10 and a panel 20.

The body 10 has a first front side 11, a first rear side 12, a first top edge 13 and a first bottom edge 14. A heel portion 15 and a toe portion 16 are disposed at two opposing ends of the body 10, respectively. The heel portion 15 has a neck portion 17 connected to a shaft (not shown). The first front side 11 has an annular groove 111.

The panel 20 is disposed on the front side 11 of the body 10 and corresponds in shape to the body 10. The panel 20 has a second top edge 21, a second bottom edge 22, a second front side 23 and a second rear side 24. The second rear side 24 has an annular rib 241. The second front side 23 is a ball-hitting surface. The second bottom edge 22 integrally extends toward the second rear side 24 to form a wall portion 25. Part of the wall portion 25 sinks to a depth for defining a bending section 26 facing the upper edge such that the wall portion 25 is divided, from the starting point of the extension to the end point thereof, into three sections, namely a first transverse section 251, the bending section 26 and a second transverse section 252. The bending section 26 comprises a leading leg segment 261, a vertex segment 262 and a trailing leg segment 263, so as to be capable of deforming and thereby generating bounce resilience. Therefore, the bending section 26 is arcuate or V-shaped, as shown in FIG. 7. The annular rib 241 of the panel 20 engages with the annular groove 111 of the body 10, by gluing, welding or screwing, such that the panel 20 is disposed on the first front side 11 of the body 10.

As soon as the panel 20 hits a ball, the bending section 26 formed from the wall portion 25 deforms and thereby generates bounce resilience. The bounce resilience generated by the bending section 26, together with resilience generated because of deformation of the second front side 23 when the panel 20 hits a ball, augments the ball-hitting force and ball-hitting distance achieved by the club head. The bending section 26 can generate the bounce resilience, provided that the bending section 26 has a predetermined length and width. In this embodiment, the length L2 of the bending section 26 is ⅛˜1 time the length L1 of the panel 20, and the length L1 of the panel 20 is equal to the maximum distance between the left end of the panel 20 and the right end of the panel 20. In this embodiment, the width W2 of the bending section 26 is ½˜ 4/8 time the width W1 of the bottom of the club head, and the width W1 of the bottom of the club head is equal to the maximum distance between the second bottom edge 22 of the panel 20 and the first bottom edge 14 of the body 10. In this embodiment, the depth H2 defining the bending section 26 is equal to 5/100˜ 30/100 time the maximum distance H1 between the second top edge 21 and the second bottom edge 22.

Although the bending section 26 in the first embodiment is in the number of one, the bending section 26 in the second embodiment is in the number of two. Referring to FIG. 8, in the second embodiment of the present disclosure, the club head conducive to enhancement of resilience comprises a body 10 and a panel 20. Two bending sections 26 are formed discretely from the wall portion 25 and aligned along the long axis of the panel 20. A discrete segment 27 is disposed between the two bending sections 26 and adapted to provide weak bounce resilience. Therefore, the position and width of the discrete segment 27 can be changed in order to change the ball-hitting force of the panel, thereby adjusting the ball-hitting distance and ball-hitting direction of the club head.

In the second embodiment of the present disclosure, the total length of the two bending sections is ⅛˜ 9/10 time the length L1 of the panel, and the length L1 of the panel is equal to the maximum distance between the left end of the panel and the right end of the panel. The two bending sections are of equal or unequal length. In the second embodiment of the present disclosure, the width of the two bending sections is ½˜⅛ time the width W1 of the bottom of the club head, and the width W1 of the bottom of the club head is equal to the maximum distance between the first bottom edge 22 and the second bottom edge 14. The two bending sections are of equal or unequal width.
