Adjustable weight retention assembly

Abstract

An adjustable weight retention assembly comprising a hollow body having first outer diameter and a proximal and distal end; a flange abutting the proximal end having a second outer diameter greater larger than the first; and a plurality of concentric rings circumscribing the hollow body; wherein the assembly is formed of a high specific gravity polymer composition. A set of golf clubs containing a plurality of adjustable weight retention assemblies, as well as a set of adjustable weight retention assemblies are also described.

         2 . The assembly of  claim 1 , wherein the hollow body further comprises a bisecting slit.  
     
     
         3 . The assembly of  claim 1 , wherein the proximal end comprises a first aperture and the distal ends comprises a second aperture.  
     
     
         4 . The assembly of  claim 1 , wherein the body comprises three concentric rings.  
     
     
         5 . The assembly of  claim 1 , wherein the rings are elevated above the first outer diameter.  
     
     
         6 . The assembly of  claim 5 , wherein the rings are elevated between about 0.002 inches and about 0.010 inches.  
     
     
         7 . The assembly of  claim 1 , wherein the rings are recessed below the first outer diameter.  
     
     
         8 . The assembly of  claim 7 , wherein the rings are recessed between about 0.002 inches and about 0.010 inches.  
     
     
         9 . The assembly of  claim 1 , wherein the polymer composition comprises high specific gravity thermoplastic compounds; crystalline thermoplastics or elastomers with high-density fillers; nylons, polypropylenes, ABS, polyesters, polyester elastomers, PBT, nylon elastomers, urethanes, and mixtures thereof.  
     
     
         10 . The assembly of  claim 1 , wherein the polymer composition has a specific gravity of between about 1.7 and about 10.  
     
     
         11 . The assembly of  claim 10 , wherein the specific gravity of between about 4 and about 10.  
     
     
         12 . The assembly of  claim 1 , wherein the flange has a thickness of between about 0.02 inches and about 0.05 inches.  
     
     
         13 . The assembly of  claim 12 , wherein the flange has a thickness of between about 0.03 inches and about 0.04 inches.  
     
     
         14 . The assembly of  claim 1 , wherein the hollow body has a length of between about 0.5 inches and about 2 inches.  
     
     
         15 . A set of golf clubs comprising a plurality of adjustable weight retention assemblies comprising: 
 a hollow body having first outer diameter and a proximal and distal end;    a flange abutting the proximal end having a second outer diameter greater larger than the first; and    a plurality of concentric rings circumscribing the hollow body;    wherein the assemblies are formed of a high specific gravity polymer composition and each assembly in the set has a differing and increasing weight.    
     
     
         16 . A set of adjustable weight retention assemblies comprising: 
 a hollow body having first outer diameter and a proximal and distal end;    a flange abutting the proximal end having a second outer diameter greater larger than the first; and    a plurality of concentric rings circumscribing the hollow body;    wherein the assemblies are formed of a high specific gravity polymer composition and each assembly in the set has a differing and increasing weight.    
     
     
         17 . The set of assemblies of  claim 16 , wherein the set comprises 5 assemblies comprising: 
 a first assembly having a first weight;    a second assembly having a second weight greater than the first;    a third assembly having a third weight greater than the second;    a fourth assembly having a fourth weight greater than the third; and    a fifth assembly having a fifth weight greater than the fourth.    
     
     
         18 . The set of  claim 17 , wherein the weights increase by at least about 2 g.
