Abstract

An interchangeable golf putting system with variable loft, convex face, and vertical weighting system, including a removeable hosel to permit the on-demand interchangeability of the head balance. An interchangeable head to permits the on-demand interchangeability between one or more radiuses of a convex head face, or to a flat face. An interchangeable weight allows the on-demand interchangeability of the weight of the putter. The putter also allows for interchangeability between the blade, mallet, and wing styles.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . An interchangeable golf putter system with variable loft, convex face, and weighting system, comprising:
 a removeable hosel to permit the on-demand interchangeability among multiple hosels to modify the head balance;   an interchangeable head to permit the on-demand interchangeability between one or more radiuses of a convex putter face at 12.01 inch or greater, or to a flat face; and   an interchangeable weight to allow the on-demand interchangeability of the weight of the putter.   
     
     
         2 . The apparatus of  claim 1 , wherein the interchangeable head is a blade configuration. 
     
     
         3 . The apparatus of  claim 1 , wherein the interchangeable head is a mallet configuration. 
     
     
         4 . The apparatus of  claim 1 , wherein the interchangeable head is a “half-mallet” as described as a Wing. 
     
     
         5 . The apparatus of  claim 1 , wherein the removeable hosel permits a face balanced configuration. 
     
     
         6 . The apparatus of  claim 1 , wherein the removeable hosel permits a toe-weighted configuration. 
     
     
         7 . The apparatus of  claim 1 , wherein the weight is comprised of a vertical metal, composite, or plastic plate insert. 
     
     
         8 . The apparatus of  claim 1 , wherein the weight is comprised of at least one of the following materials: stainless steel, copper, zinc, titanium, milled steel, forged steel, aluminum, other alloys, composite, thermoplastic or thermosets. 
     
     
         9 . The apparatus of  claim 1 , wherein the interchangeable head is comprised of at least one of the following materials: stainless steel, copper, zinc, titanium, milled steel, forged steel, aluminum, or other alloys. 
     
     
         10 . The apparatus of  claim 1 , wherein the removeable hosel allows for a shaft of the putter to be positioned in an onset placement. 
     
     
         11 . The apparatus of  claim 1 , wherein the removeable hosel allows for a shaft of the putter to be positioned in an offset placement. 
     
     
         12 . The apparatus of  claim 1 , wherein the removeable hosel allows for a shaft of the putter to be positioned in a center set placement. 
     
     
         13 . The apparatus of  claim 1 , wherein the head face has a variable loft to provide a constant loft during the putting stroke. 
     
     
         14 . An interchangeable convex golf putter with variable loft and weighting system, comprising:
 a removeable hosel to permit the on-demand interchangeability of the head balance;   an interchangeable head to permit the on-demand interchangeability between one or more radiuses of a head face, or to a flat face, the head face including a variable loft to provide a constant loft during the putting stroke;   an interchangeable weight to allow the on-demand interchangeability of the weight of the putter, wherein the interchangeable weight is positioned between a head back and the head face, and wherein the interchangeable weight is coupled to the head back and the head face via one or more bolts.   
     
     
         15 . The apparatus of  claim 13 , wherein the interchangeable head is a blade configuration or a mallet configuration. 
     
     
         16 . The apparatus of  claim 13 , wherein the removeable hosel permits a face balanced configuration. 
     
     
         17 . The apparatus of  claim 13 , wherein the removeable hosel permits a toe-weighted configuration. 
     
     
         18 . The apparatus of  claim 13 , wherein the weight is comprised of a vertical metal, composite, or plastic plate insert. 
     
     
         19 . The apparatus of  claim 13 , wherein the weight is comprised of at least one of the following materials: stainless steel, copper, zinc, titanium, milled steel, forged steel, aluminum, or other alloys. 
     
     
         20 . The apparatus of  claim 13 , wherein the interchangeable head is comprised of at least one of the following materials: stainless steel, copper, zinc, titanium, milled steel, forged steel, aluminum, or other alloy. 
     
     
         21 . The apparatus of  claim 13  wherein the removeable hosel allows for a shaft of the putter to be positioned in an onset placement, an offset placement, or a center set placement.
