Golf club head having complex striking plate structure

Abstract

A golf club head includes a golf club head body and a striking plate connected thereto. The striking plate includes a first plate, a second plate and elastically deformable spaces. The first plate has a front surface to provide a striking surface, and a rear surface to provide a first connecting surface. The second plate has a front surface to provide a second connecting surface, and a rear surface. The first connecting surface of the first plate is attached to the second connecting surface of the second plate to form the striking plate which is connected to a front portion of the golf club head body. The elastically deformable spaces are formed between the first connecting surface of the first plate and the second connecting surface of the second plate.

1 . A golf club head, comprising:
 a golf club head body;   a first plate having a front surface to provide a striking surface, and a rear surface to provide a first connecting surface;   a second plate having a second connecting surface, a rear surface and a plurality of upraised engaging members, the second connecting surface being attached to the first connecting surface of the first plate to form a complex striking plate; and   at least one elastically deformable space formed between the first connecting surface of the first plate and the second connecting surface of the second plate;   wherein the complex striking plate connects with the golf club head body to provide a degree of elastic deformability while striking a golf ball.   
   
   
       2 . The golf club head as defined in  claim 1 , further including a plurality of upraised engaging members formed on the second connecting surface of the second plate to engage with the first connecting surface of the first plate. 
   
   
       3 . The golf club head as defined in  claim 2 , wherein formed between the first connecting surface of the first plate and the upraised engaging member of the second plate is a connecting layer selectively formed from one of a braze welding layer, an explosion welding layer, a press rolling layer and an adhesive layer. 
   
   
       4 . The golf club head as defined in  claim 2 , wherein the upraised engaging member formed from an upright rib, a tilted rib or a saw-toothed member. 
   
   
       5 . The golf club head as defined in  claim 2 , wherein the second plate is made from a single sheet formed with sine waves, square waves, triangular waves or zigzag shapes. 
   
   
       6 . The golf club head as defined in  claim 1 , further including a plurality of protruded reinforcing members formed on the first connecting surface of the first plate. 
   
   
       7 . The golf club head as defined in  claim 6 , wherein the protruded reinforcing members are formed from upright ribs or upright blocks. 
   
   
       8 . The golf club head as defined in  claim 6 , wherein the protruded reinforcing members and the upraised engaging members are arranged in a staggered manner when the first plate and the second plate are combined together. 
   
   
       9 . The golf club head as defined in  claim 6 , wherein the protruded reinforcing members engage with the upraised engaging members when the first plate and the second plate are combined together. 
   
   
       10 . The golf club head as defined in  claim 1 , wherein each of the protruded reinforcing members extends into any two of the adjacent upraised engaging members, and is not in contact with the second connecting surface of the second plate. 
   
   
       11 . The golf club head as defined in  claim 1 , further including a third plate attached to the rear surface of the second plate. 
   
   
       12 . The golf club head as defined in  claim 11 , wherein another elastically deformable space is formed between the second plate and the third plate. 
   
   
       13 . The golf club head as defined in  claim 11 , wherein the third plate is made from a material possessing a high degree of elastic deformability. 
   
   
       14 . The golf club head as defined in  claim 11 , wherein the third plate is made from a material possessing a high degree of vibration absorbability. 
   
   
       15 . A golf club head, comprising:
 a golf club head body;   a complex striking plate connected with the golf club head body, the complex striking plate having a first plate and a second plate;   a plurality of elastically deformable spaces formed between the first plate and the second plate; and   a plurality of connecting layers formed between the first plate and the second plate, the connecting layer separating any two of the adjacent elastically deformable spaces;   wherein the elastically deformable spaces of the complex striking plate provides a degree of elastic deformability while striking a golf ball.   
   
   
       16 . The golf club head as defined in  claim 15 , wherein the connecting layer is selectively formed from one of a braze welding layer, an explosion welding layer, a press rolling layer and an adhesive layer. 
   
   
       17 . The golf club head as defined in  claim 15 , wherein the complex striking plate further including a third plate attached to a rear surface of the second plate. 
   
   
       18 . The golf club head as defined in  claim 15 , wherein another elastically deformable spaces are formed between the second plate and the third plate. 
   
   
       19 . The golf club head as defined in  claim 15 , wherein the third plate is made from a material possessing a high degree of elastic deformability. 
   
   
       20 . The golf club head as defined in  claim 15 , wherein the third plate is made from a material possessing a high degree of vibration absorbability.
