This application claims priority of Taiwanese Invention Patent Application No. 107124610, filed on Jul. 17, 2018.
The disclosure relates to a striking plate of a golf club head, and more particularly to a striking plate of a golf club head which is formed with a rib member.
A golf club utilizes a striking plate to hit a golf ball, and thus the features of the striking plate directly affect the hitting performance of a player. High impact resistance strength and high coefficient of restitution of the striking plate are the key features that are sought by players in order to hit the golf ball easily. However, it is often necessary to greatly reduce the thickness of the striking plate so as to increase the coefficient of restitution. On the other hand, thinning of the striking plate will cause the strength thereof to be diminished. Therefore, balancing the strength of the striking plate and providing a high coefficient of restitution thereof is a long-standing technical problem in the field of golfing that needs to be resolved.
Therefore, an object of the disclosure is to provide a striking plate of a golf club head that can alleviate at least one of the drawbacks of the prior art. A golf club head including the striking plate is also provided.
According to an aspect of the disclosure, a striking plate for connecting a shell of a golf club head, which has a sole, a crown, a toe and a heel, includes a plate body and at least one rib member.
The plate body has a crown-connecting side configured to connect the crown of the shell, a sole-connecting side configured to connect the sole, a toe-connecting side configured to connect the toe, a heel-connecting side configured to connect the heel, a central portion that is surrounded by the crown-connecting side, the sole-connecting side, the toe-connecting side and the heel-connecting side, a front striking face, and a rear face opposite to the front striking face.
The at least one rib member includes two opposite end portions connected to and projecting rearwardly from the rear face, and a bridge portion connected between the two opposite end portions and spaced apart from the rear face. One of the two opposite end portions is proximal to one of the crown-connecting side and the toe-connecting side, and the other one of the two opposite end portions is proximal to one of the sole-connecting side and the heel-connecting side.
According to another aspect of the disclosure, a golf club head includes a shell having a sole, a crown, a toe, a heel, and an inner chamber surrounded by the sole, the crown, the toe and the heel, and a striking plate.
The striking plate covers the inner chamber and has a plate body and at least one rib member. The plate body has a crown-connecting side connecting the crown, a sole-connecting side that connects the sole, a toe-connecting side that connects the toe, a heel-connecting side that connects the heel, a central portion that is surrounded by the crown, the sole, the toe-connecting side and the heel-connecting side, a front striking face, and a rear face opposite to the front striking face and facing the inner chamber.
The at least one rib member includes two opposite end portions connected to and projecting rearwardly from the rear face, and a bridge portion connected between the two opposite end portions and spaced apart from the rear face. One of the two opposite end portions is proximal to one of the crown-connecting side and the toe-connecting side, and the other one of the two opposite end portions is proximal to one of the sole-connecting side and the heel-connecting side.
Other features and advantages of the disclosure will become apparent in the following detailed description of the embodiment(s) with reference to the accompanying drawings, of which:
Before the disclosure is described in greater detail, it should be noted that where considered appropriate, reference numerals or terminal portions of reference numerals have been repeated among the figures to indicate corresponding or analogous elements, which may optionally have similar characteristics.
The plate body 31 has a first width (W1) along a first direction (B) parallel to a line passing through the central portion 311 and connecting between the crown-connecting side 312 and the sole-connecting side 313, and a second width (W2) along a second direction (C) parallel to a line passing through the central portion 311 and connecting between the toe-connecting side 314 and the heel-connecting side 315. The second width (W2) is greater than the first width (W1). The two opposite end portions 321 of the at least one rib member 32 is spaced apart along one of the first and second directions (B, C), and the bridge portion 322 of the at least one rib member 32 extends along one of the first and second directions (B, C). In this embodiment, the bridge portion 322 of the at least one rib member 32 curvedly extends along the first direction (B), and the two opposite end portions 321 is respectively proximal to the crown-connecting side 312 and the sole-connecting portion 313 of the plate body 31.

The results in Table 1 show that the golf club heads 1 having the at least one rib member 32 have higher hitting surface stress, indicating better hitting surface stress than that of a conventional golf club head without the at least one rib member 32. While Groups 3-1, 3-2, 6 generate satisfying hitting surface stress, each of the Groups 5-1, 5-2, 2-1 and 2-2 generates a much higher hitting surface stress. Groups 5-1 and 5-2, in which the bridge portion 322 of the at least one rib member 32 is spaced apart from the plate body 31 along the third direction (A) by the maximum distance of 8 mm, and the two opposite end portions 321 extend straightly from the plate body 31, exhibits the best ball-hitting performance of the striking plate 3.
In summary, a high coefficient of restitution value is obtained through the spring-like effect of the at least one rib member 32, while the bridge portion 322 of the at least one rib member 32 provides a high structural strength, and thereby the striking plate 3 of the golf head club 1 of this disclosure simultaneously has a high coefficient of restitution value and a high structural strength, in addition to having practical values and is available in various forms and/or designs.
In the description above, for the purposes of explanation, numerous specific details have been set forth in order to provide a thorough understanding of the embodiment(s). It will be apparent, however, to one skilled in the art, that one or more other embodiments may be practiced without some of these specific details. It should also be appreciated that reference throughout this specification to “one embodiment,” “an embodiment,” an embodiment with an indication of an ordinal number and so forth means that a particular feature, structure, or characteristic may be included in the practice of the disclosure. It should be further appreciated that in the description, various features are sometimes grouped together in a single embodiment, figure, or description thereof for the purpose of streamlining the disclosure and aiding in the understanding of various inventive aspects, and that one or more features or specific details from one embodiment may be practiced together with one or more features or specific details from another embodiment, where appropriate, in the practice of the disclosure.
While the disclosure has been described in connection with what is (are) considered the exemplary embodiment(s), it is understood that this disclosure is not limited to the disclosed embodiment(s) but is intended to cover various arrangements included within the spirit and scope of the broadest interpretation so as to encompass all such modifications and equivalent arrangements.
