Golf club head

Abstract

A golf club head includes a striking plate, a base block, a connecting unit and a bottom plate. The striking plate includes a bottom end and a top end. The base block is disposed separately from and extending away from the bottom end of the striking plate. The connecting unit is connected to the striking plate and the base block. The bottom plate is formed as a separate piece from the striking plate and the base block, and is connected to the bottom end of the striking plate and the base block. The base block and the bottom plate cooperatively form a sole portion of the golf club head and define a recess therebetween.

1 . A golf club head, comprising:
 a striking plate that includes a bottom end and a top end;   a base block that is disposed separately from and extending away from said bottom end of said striking plate;   a connecting unit that is connected to said striking plate and said base block; and   a bottom plate that is formed as a separate piece from said striking plate and said base block, and that is connected to said bottom end of said striking plate and said base block,   wherein said base block and said bottom plate cooperatively form a sole portion of said golf club head and define a recess therebetween,   wherein said base block further includes a base portion that is connected to said bottom plate, and an extending portion that extends from said base portion toward said striking plate and that is spaced apart from said bottom plate, said recess being formed among said base portion, said extending portion and said bottom plate.   
     
     
         2 . The golf club head as claimed in  claim 1 , wherein said striking plate further includes:
 a plate body having a striking face,   a bottom bent portion which has said bottom end and which is bent and extends from said plate body away from said striking face and toward said base block, and   a top bent portion which has said top end, which is disposed opposite to said bottom bent portion, and which is bent and extends from said plate body away from said striking face.   
     
     
         3 . The golf club head as claimed in  claim 2 , wherein said plate body further has a rear face opposite to said striking face, said connecting unit connecting to said rear face of said plate body, said top bent portion and said base block. 
     
     
         4 . The golf club head as claimed in  claim 2 , wherein said extending portion of said base block extends toward said plate body of said striking plate. 
     
     
         5 . The golf club head as claimed in  claim 4 , wherein said extending portion of said base block and said bottom plate are spaced apart by a distance of less than 6 mm. 
     
     
         6 . The golf club head as claimed in  claim 4 , wherein said extending portion of said base block and said plate body of said striking plate are spaced apart by a distance ranging from 1 mm to 6 mm. 
     
     
         7 . The golf club head as claimed in  claim 4 , further comprising a weight block connected to said extending portion of said base block and disposed in said recess. 
     
     
         8 . The golf club head as claimed in  claim 7 , wherein said weight block is spaced apart from said bottom plate by a distance of less than 6 mm. 
     
     
         9 . The golf club head as claimed in  claim 1 , wherein said striking plate further includes a surrounding portion that is connected to said connecting unit and said bottom plate, and that defines an opening, and a plate body that is connected to said surrounding portion to cover said opening, said surrounding portion having said top end and said bottom end respectively at two opposite sides thereof. 
     
     
         10 . The golf club head as claimed in  claim 1 , wherein said connecting unit includes a connecting part and a cover part, said connecting part being connected to the top end of the striking plate, forming a crown portion of said golf club head, and cooperating with said base block to define an opening, said cover part interconnecting said connecting part and said base block to cover said opening. 
     
     
         11 . The golf club head as claimed in  claim 1 , wherein said bottom plate has a thickness ranging from 1 to 4 mm. 
     
     
         12 . The golf club head as claimed in  claim 1 , wherein said bottom plate is made from a material different from those of said striking plate and said base block. 
     
     
         13 . The golf club head as claimed in  claim 7 , wherein said weight block extends from said extending portion downwardly towards said bottom plate.
