Peripheral-weighted putter head

Abstract

A golf putter head having a toe and a heel. The putter head has a face defining a ball-striking portion and lateral portions extending from the ball-striking portion toward the toe and the heel. There is a rear section spaced from the face, and a connecting section extending from the ball-striking portion of the face to the rear section. A pair of elongated weights, one weight coupled at one end to each of the lateral portions of the face at locations equidistant from the ball-striking portion, and each weight also coupled at its other end to the rear section, accomplish balanced peripheral weighting. The weights are preferably replaceable.

1 . A golf putter head having a toe and a heel, comprising: 
 a face defining a ball-striking portion and lateral portions extending from the ball-striking portion toward the toe and the heel;    a rear section spaced from the face;    a connecting section extending from the ball-striking portion of the face to the rear section; and    a pair of elongated weights, one weight coupled at one end to each of the lateral portions of the face at locations equidistant from the ball-striking portion, and each weight also coupled at its other end to the rear section, to accomplish balanced peripheral weighting.    
   
   
       2 . The golf club putter head of  claim 1 , wherein the weights are removably coupled to both the face and the rear section, to allow their replacement.  
   
   
       3 . The golf club putter head of  claim 2 , wherein the removable coupling is accomplished with threaded connecting members.  
   
   
       4 . The golf club putter head of  claim 1 , wherein the face, the rear section and the connecting section are unitary.  
   
   
       5 . The golf club putter head of  claim 4 , wherein the lateral width of the face and of the rear section are about the same.  
   
   
       6 . The golf club putter head of  claim 5 , wherein the connecting section has a lateral width that is about the same as the ball-striking portion.  
   
   
       7 . The golf club putter head of  claim 6 , wherein the ball-striking portion is substantially circular.  
   
   
       8 . The golf club putter head of  claim 7 , wherein the connecting section is substantially cylindrical along at least a part of its length.  
   
   
       9 . The golf club putter head of  claim 8 , wherein the connecting section defines an elongated slot along its top.  
   
   
       10 . The golf club putter head of  claim 9 , wherein the slot extends through the thickness of the connecting section, to divide the connecting section into two part cylinders.  
   
   
       11 . The golf club putter head of  claim 10 , wherein the rear section comprises two distinct portions, one integral with each part cylinder.  
   
   
       12 . The golf club putter head of  claim 11 , wherein the two distinct portions of the rear section lie essentially at right angles to the slot.  
   
   
       13 . The golf club putter head of  claim 8 , wherein the connecting section is flattened at its lower circumferential region.  
   
   
       14 . The golf club putter head of  claim 8 , wherein the lateral portions of the face are not as high as the cylinder, to define narrowed wings extending from the ball-striking portion.  
   
   
       15 . The golf club putter head of  claim 14 , wherein the lower edges of the wings rise up along their length toward the heel and toe.  
   
   
       16 . The golf club putter head of  claim 14 , wherein the weights are connected near the tips of the wings.  
   
   
       17 . The golf club putter head of  claim 16 , wherein the weights have a substantially circular cross-section.  
   
   
       18 . The golf club putter head of  claim 17 , wherein the substantially circular cross-section extends along at least much of the length of the weights.  
   
   
       19 . The golf club putter head of  claim 18 , wherein the substantially circular cross-section extends along effectively the entire length of the weights.  
   
   
       20 . The golf club putter head of  claim 18 , wherein the diameter of the weights varies along their length.  
   
   
       21 . The golf club putter head of  claim 20 , wherein the diameter of the weights is largest near their center.  
   
   
       22 . The golf club putter head of  claim 21 , wherein the diameter of the weights tapers from the largest point toward the front that is coupled to the face.  
   
   
       23 . The golf club putter head of  claim 22 , wherein the diameter of the weights tapers from the largest point toward the back that is coupled to the rear section.  
   
   
       24 . The golf club putter head of  claim 23 , wherein the taper of the weights toward the front is greater than it is toward the back.  
   
   
       25 . The golf club putter head of  claim 1 , further comprising a hosel for accepting a club shaft.  
   
   
       26 . The golf club putter head of  claim 25 , wherein the hosel is in the connecting section.  
   
   
       27 . A golf putter head having a toe and a heel, comprising: 
 a face defining a substantially circular ball-striking portion, and narrowed lateral portions extending from the ball-striking portion toward the toe and the heel;    a rear section spaced from and essentially parallel to the face;    a connecting section extending from the ball-striking portion of the face to the rear section;    wherein the face, rear section and the connecting section are unitary; and    a pair of removable elongated weights, one weight removably coupled at one end to each of the lateral portions of the face at locations equidistant from the ball-striking portion, and each weight also removably coupled at its other end to the rear section, to accomplish balanced peripheral weighting.
