STRIKE PLATE OF A GOLF CLUB HEAD
A strike plate of a golf club head has a striking zone and an elastic annular part defined around the striking zone and adjacent to the edge of the strike plate. Multiple annular grooves are formed in the elastic annular part on the rear face of the strike plate and are arranged at intervals. Multiple annular flanges are formed on the rear face. Each annular flange is formed between two adjacent annular grooves. The elastic annular part with multiple thicker and thinner parts alternately arranged provides elasticity as a spring. Therefore, when any part of the striking zone of the strike plate is stricken on the golf ball, the elastic annular part generates a sufficient elastic effect to effectively enlarge the sweet spot on the strike plate.
1. Field of the Invention
The present invention relates to a golf club head, especially to a strike plate of the golf club head.
2. Description of the Prior Arts
A conventional golf club head comprises a head body and a strike plate attached securely to a front face of the head body. The head body has a hosel formed on an end thereof and opposite to the strike plate for receiving a shaft to form a golf club.
When the user hits the golf ball with the conventional golf club, the strike plate on the front face of the head body strikes the golf ball. Thus, the strike plate plays important roles in the striking performance of the golf club.
The strike plate of the conventional golf club heads is mostly made of a plate of uniform thickness. Only by using metal material with high strength and high elasticity without modifying the structures, the reacting elastic force resulted from striking the golf ball by the strike plates is limited. Moreover, the edge of the strike plate is attached securely to the head body. As the head body holds the edge of the strike plate, only the central part of the strike plate provides elastic effect. Then the striking sweet spot of the conventional strike plate only occupies a small area of the conventional strike plate. Therefore, the user cannot easily strike the golf ball on the sweet spot of the conventional strike plate.
Additionally, a conventional strike plate is developed with a protrusion formed on a center of a rear face thereof to form a structure having a thicker center and a thinner edge. The thinner area enhances the elasticity of the edge of the conventional strike plate so that the conventional strike plate provides elastic effect while striking.
However, the edge of the aforementioned conventional strike plate with the central protrusion on the rear face still has a certain thickness such that the enhanced elastic effect is still insufficient.
To overcome the shortcomings, the present invention provides a strike plate of a golf club head to mitigate or obviate the aforementioned problems.
SUMMARY OF THE INVENTIONThe main objective of the present invention is to provide a strike plate of a golf club head. The strike plate of a golf club head has a striking zone and an elastic annular part defined around the striking zone and adjacent to the edge of the strike plate. Multiple annular grooves are formed in the elastic annular part on the rear face of the strike plate and are arranged at intervals. Multiple annular flanges are formed on the rear face. Each annular flange is formed between two adjacent annular grooves. The elastic annular part with multiple thicker and thinner parts alternately arranged provides elasticity as a spring. Therefore, when any part of the striking zone of the strike plate is stricken on the golf ball, the elastic annular part generates a sufficient elastic effect to effectively enlarge the sweet spot on the strike plate.
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.
A preferred embodiment of a strike plate 1A of a golf club head in accordance with the present invention is shown in
With reference to
In a preferred embodiment, the strike plate 1A, 1B has two to six annular grooves 111 formed on the elastic annular part 11. The width of the elastic annular part on the radial direction is preferably 3 mm to 15 mm.
