Grip sheath used for a golf club class

Abstract

A grip sheath used for a golf club includes a tapered, elongated hollow body made of an elastomer. The tapered, elongated hollow body has an open end and a closed end opposite to and larger than the open end. The hollow body is formed with a longitudinal central hole extending from the open end towards the closed end and with a plurality of longitudinal blind bores extending from the closed end towards the open end. In addition, the longitudinal blind bores are arranged around the longitudinal central hole. Therefore shock may be significantly absorbed at the grip sheath when a ball is hit by the golf club.

What is claimed is:  
     
         1 . A grip sheath used for a golf club, comprising a tapered, elongated hollow body made of an elastomer, said tapered, elongated hollow body having an open end and a closed end opposite to and larger than said open end, said tapered, elongated hollow body being formed with a longitudinal central hole extending from said open end towards said closed end and with a plurality of longitudinal blind bores extending from said closed end towards said open end, and said longitudinal blind bores being arranged around said longitudinal central hole, whereby shock may be significantly absorbed at said grip sheath when a ball is hit by said golf club.  
     
     
         2 . The grip sheath as claimed in  claim 1 , wherein said tapered, elongated hollow body is made of rubber.  
     
     
         3 . The grip sheath as claimed in  claim 1 , wherein said tapered, elongated hollow body is adapted to be formed by way of injection.  
     
     
         4 . The grip sheath as claimed in  claim 1 , wherein said longitudinal blind bores are tapered in shape.  
     
     
         5 . The grip sheath as claimed in  claim 1 , wherein said longitudinal blind bores are cylindrical in shape.  
     
     
         6 . The grip sheath as claimed in  claim 1 , wherein said longitudinal blind bores have respective channel parts in fluid communication with said longitudinal central hole.  
     
     
         7 . The grip sheath as claimed in  claim 1 , wherein said tapered, elongated hollow body is adapted to be formed by way of extrusion.  
     
     
         8 . The grip sheath as claimed in  claim 6 , wherein each of said longitudinal blind bores have a cross section substantially like a sector.  
     
     
         9 . The grip sheath as claimed in  claim 1 , wherein said tapered, elongated hollow body has a through-hole defined in a center of said closed end.
