Modular golf putter

Abstract

A modular golf putter head having a hollow body is provided. The modular putter head comprises a permeable thin center piece disposed between two substantially identical large hollow cups. The large hollow cups selectively secure to either side of the thin center piece to enable use for right-handed or left-handed golfers. The modular putter head is configured to receive one or more removable weights, wherein the removable weights can be distributed in accordance to a user's preference to provide a customized center of gravity.

1 . A modular golf club head securable to a shaft comprising:
 a center piece including a wall having a front side and an opposite back side, and a top surface and an opposite bottom surface, the top surface including a cavity for securing the shaft;   a large hollow front cup selectively securable to the front side, the large hollow front cup including a striking surface for contacting a golf ball; and   a large hollow back cup selectively securable to the back side, the large hollow back cup including a back surface;   wherein the large hollow front and back cups extend axially outward with respect to the center piece.   
   
   
       2 . The modular golf club head of  claim 1 , wherein the wall of the center piece is relatively thin; and
 wherein the center piece, the large hollow front cup, and the large hollow back cup each include at least one hole coaxially aligned with each other.   
   
   
       3 . The modular golf club head of  claim 2 , further comprising:
 at least one fastener threadable through each hole of the center piece, the large hollow front cup, and the large hollow back cup;   wherein the fastener is configured to selectively secure the large hollow front and back cups to the front and back sides, respectively.   
   
   
       4 . The modular golf club head of  claim 3 , further comprising:
 at least one removable weight, the removable weight securable therein; and   at least one alignment line disposed along a top surface of the putter head, the alignment line extending in a perpendicular direction with respect to the striking surface.   
   
   
       5 . The modular golf club head of  claim 4 , wherein the club head is a putter head. 
   
   
       6 . A modular golf putter head securable to a shaft and adaptable to right-handed and left-handed users comprising:
 a thin center piece including a wall having a front side and an opposite back side, and a top surface and an opposite bottom surface, the top surface including a cavity for securing the shaft;   a large hollow front cup selectively securable to the front side, the large hollow front cup including a striking surface for contacting a golf ball;   a large hollow back cup selectively securable to the back side, the large hollow back cup including a back surface; and   at least one removable weight, the removable weight securable therein;   wherein the large hollow front and back cups extend axially outward with respect to the center piece.   
   
   
       7 . The modular golf putter head of  claim 6 , wherein the thin center piece, the large hollow front cup, and the large hollow back cup each include at least one hole coaxially aligned with each other;
 wherein at least one fastener is threadable through each hole of the center piece, the large hollow front cup, and the large hollow back cup; and   wherein the fastener is configured to selectively secure the large hollow front and back cups to the front and back sides, respectively.   
   
   
       8 . The modular golf putter head of  claim 7 , wherein the large hollow front and back cups each include a top surface having a centered alignment line extending in a substantially perpendicular direction with respect to the striking surface and the back surface, respectively. 
   
   
       9 . The modular golf putter head of  claim 8 , wherein the striking and back surfaces are flat. 
   
   
       10 . The modular golf putter head of  claim 8 , wherein the striking and back surfaces are angled to provide a loft when the large hollow front and back cups are secured to the front and back sides, respectively. 
   
   
       11 . The modular golf putter head of  claim 10 , wherein the lofts of the striking and back surfaces are each three degrees from vertical. 
   
   
       12 . The modular golf putter head of  claim 6 , wherein the bottom surface of the center piece is convex, the convex bottom surface having an apex configured to provide minimal contact with golf surfaces. 
   
   
       13 . The modular golf putter head of  claim 6 , wherein the bottom surface of the center piece is substantially flat. 
   
   
       14 . The modular club head of  claim 6 , wherein the large hollow front and back cups are interchangeable.
