Grip of golf club and its manufacture method

Abstract

The present invention relates to a grip of golf club and manufacture method, which has a foaming interlayer with damping effect, and an anti-slip surface mechanism-the rubber collars and the rubber-fiber composite in spacing arrange on the outside surface of the surround. Its manufacture method includes that pre-mould a rubber core bar with a collar indentation, and fill out the foaming blowing agent in the collar indentation; then cut out the raw rubber sheet suiting to cover on the outside of the foaming material, and layover the fiber mesh on the raw rubber sheet, next stick the rubber collars on the outside of the fiber mesh layer in spacing arrange axially to combine the surround; then gum the combined surround layer up on the core bar collar indentation portion filled with foaming material for standing by. Finally process the semi-finished grip in the mould with heating setting treat and sulphurating treat.

I claim:  
     
         1 . A manufacture method of the grip of golf club, wherein pre-mould a rubber core bar with a collar indentation, and fill out the foaming material in the collar indentation; then cut out the raw rubber sheet suiting to cover on the outside of the foaming material, and layover the fibre mesh on the raw rubber sheet, next stick the rubber collars on the outside of the fibre mesh layer in spacing arrange axially to combine the surround; then gum the combined surround layer up on the core bar collar indentation portion filled with foaming material be a semi-finished article for standing by; finally process the semi-finished grip in the mould with heating setting treat and sulphurating treat so that the foaming material fills out the space between the collar indentation and the inside of the surround to form a damping interlayer, and an anti-slip surface mechanism-the rubber collars and the rubber-fibre composite in spacing arrange on the outside surface of the surround.  
     
     
         2 . A manufacture method of the grip of golf club as claimed in  claim 1 , wherein in processing, for avoiding the foaming material overflowing from the seaming of the surround, before gumming the surround up on the foaming material, pre-lay a thin raw rubber type on the surface of foaming material opposite the seaming portion of the surround to screen the under foaming material at inside.  
     
     
         3 . A manufacture method of the grip of golf club as claimed in  claim 1 , wherein in processing, for avoiding the foaming material overflowing from the seaming of the surround, before gumming the surround up on the foaming material, laps joint the both side edges of the surround together to seal the seaming.  
     
     
         4 . A manufacture method of the grip of golf club as claimed in  claim 1 , wherein for avoiding the foaming material overflowing from the both joint ends between the rims of the collar indentation and the surround, before gumming the surround up on the foaming material, pre-lay a raw rubber type on inside of the joint portion for screening the joint separately to screen the joints.  
     
     
         5 . A grip of golf club consisting of a core bar, an expanded sandwiching, and a surround, wherein, the core bar has a collar indentation for retaining the expanded sandwiching and the surround sequentially from inner to outer; the surround is an anti-slip cover in which the rubber collars are covered on the hoop rubber and rubber-fibre composite's surfaces in spacing arrange axially.
