Modular golf club

Abstract

A modular golf club includes a head, a top shaft and a connector shaft between the head and the top shaft. The connector shaft has a couple of identical fastening means at both ends thereof. The fastening means is an insertion tip in the shape of regular hexagon and a union nut secured to the connector shaft slidably but with a limit defined by a radial flange at the base of the hexagonal tip. Either union nut has an inner thread toward its outer end the diameter of which is bigger than the flange to allow the union nut to be positioned over the hexagonal tip in a juxtaposed relationship.

       8 . A modular golf club comprising: 
 a shaft section having a top grip at a top end, and a protrusion having a noncircular cross section protruding from the bottom end,    an internally threaded collar nut rotably mounted in a common axial position to the shaft section,    a plurality of clubheads, each having a slot for snugly receiving the protrusion and each having an external thread for receiving the internally threaded collar nut, wherein the protrusion does not rotate relative to the slot when inserted in the slot.    
   
   
       9 . The modular golf club of  claim 8 , wherein the protrusion has a pointed flathead tip for insertion into the slot, wherein the slot is shaped to receive the flathead tip.  
   
   
       10 . The modular golf club of  claim 8 , further comprising a radial flange at a base of the protrusion, wherein the protrusion can be inserted into the slot until the flange abuts the shaft, whereby the internally threaded collar nut can be tightened to complete axial and radial connection.  
   
   
       11 . The modular golf club of  claim 10 , wherein the slot shaped as a regular hexagon and the protrusion is a similarly sized regular hexagon.  
   
   
       12 . The modular golf club of  claim 10 , wherein the protrusion terminates in a flat head and the slot is shaped to receive the protrusion.  
   
   
       13 . The modular golf club of  claim 1 , wherein the club lengths vary due to varying hosel length.  
   
   
       14 . A modular golf club comprising: 
 a selection of clubheads, each having a protrusion having a noncircular cross section protruding from the hosel,    an internally threaded collar nut rotably mounted in a common axial position to the hosel,    a shaft section having a top grip at a top end, and at a bottom end, a slot for snugly receiving the protrusion, wherein the bottom end has an external thread for receiving the internally threaded collar nut.    
   
   
       15 . The modular golf club of  claim 14 , wherein the protrusion has a pointed tip for insertion into the slot, wherein the slot is shaped to receive the pointed tip.  
   
   
       16 . The modular golf club of  claim 15 , further comprising a radial flange at a base of the protrusion, wherein the protrusion can be inserted into the slot until the flange abuts the shaft, whereby the internally threaded collar nut can be tightened to complete axial and radial connection so that the golf club is locked in radial orientation as well as longitudinal orientation.  
   
   
       17 . The modular golf club of  claim 14 , wherein the slot is shaped as a regular hexagon and the protrusion is a similarly sized regular hexagon.  
   
   
       18 . The modular golf club of  claim 14 , wherein the protrusion terminates in a pointed flat head tip and the slot is shaped to receive the protrusion.
