Golf putter

Abstract

The putter head is constructed with a front face with a small loft angle of from 0° to 10°. The club head has a center of gravity that is located behind the face and below a plane passing through the point of contact of the putter head and the center of gravity of the struck golf ball.

1 . A golf putter head having a front face for impacting against a golf ball at a predetermined contact point within a horizontal plane and having a center of gravity disposed below and behind the face and below and behind said horizontal plane and said contact point.  
   
   
       2 . A golf putter head as set forth in  claim 1  wherein said front face is disposed angularly of a vertical plane between zero and ten degrees or a convex face in either or both the vertical and the horizontal planes.  
   
   
       3 . A golf putter head as set forth in  claim 2  wherein said front face is disposed at an angle of 3° to said vertical plane.  
   
   
       4 . A golf putter head as set forth in  claim 1  having a contoured shape in a horizontal plane including a pair of rearwardly directed lobes disposed in symmetric relation about a centerline of said head.  
   
   
       5 . A golf putter head as set forth in  claim 4  wherein said contoured shape includes a triangular section and said lobes extend symmetrically from said triangular section.  
   
   
       6 . A golf putter head as set forth in  claim 4  further having a pair of weights, each said weight being mounted in an upper surface of a respective lobe.  
   
   
       7 . A golf putter head as set forth in  claim 4  further having a pair of recesses in an upper surface thereof, said recesses being disposed symmetrically of said centerline.  
   
   
       8 . A golf putter head as set forth in  claim 4  further having a recess in an upper surface thereof forwardly of said lobes.  
   
   
       9 . A golf putter head as set forth in  claim 1  having a transversely extending shoulder at a forward end and a bore in said shoulder for receiving a shaft.  
   
   
       10 . A golf putter head as set forth in  claim 9  wherein said bore is disposed at an obtuse angle to a horizontal plane.  
   
   
       11 . A golf putter head as set forth in  claim 9  wherein said obtuse angle is 72°.  
   
   
       12 . A golf putter head as set forth in  claim 9  having a groove in an upper surface of said shoulder extending perpendicularly of said bore and parallel to said front face for alignment of said front face perpendicularly to an imaginary line extending from said front face to a cup.  
   
   
       13 . A golf putter head having a contoured shape in a horizontal plane including a triangular section and a pair of lobes extending from said triangular section in symmetric relation about a centerline of said triangular section, a front face for impacting against a golf ball at a predetermined contact point on said centerline and within a horizontal plane and a center of gravity disposed below said horizontal plane and said contact point.  
   
   
       14 . A golf putter head as set forth in  claim 13  wherein said front face is disposed angularly of a vertical plane.  
   
   
       15 . A golf putter head as set forth in  claim 13  further having a pair of weights, each said weight being mounted in an upper surface of a respective lobe.  
   
   
       16 . A golf putter head as set forth in  claim 13  further having a pair of recesses in an upper surface thereof, said recesses being disposed symmetrically of said centerline.  
   
   
       17 . A golf putter head as set forth in  claim 13  further having a recess in an upper surface thereof forwardly of said lobes.  
   
   
       18 . A golf putter head as set forth in  claim 13  having a transversely extending shoulder at a forward end and a bore in said shoulder for receiving a shaft.  
   
   
       19 . A golf putter head as set forth in  claim 18  having a groove in an upper surface of said shoulder extending perpendicularly of said bore and parallel to said front face for alignment of said front face perpendicularly to an imaginary line extending from said front face to a cup.  
   
   
       20 . A golf putter comprising 
 a head having a front face for impacting against a golf ball at a predetermined contact point within a horizontal plane, a center of gravity disposed below said horizontal plane and said contact point, a transversely extending shoulder at a forward end and a bore in said shoulder; and    a shaft received in said bore.    
   
   
       21 . A golf putter as set forth in  claim 20  wherein said head has a contoured shape in a horizontal plane including a triangular section and a pair of lobes extending from said triangular section in symmetric relation about a centerline of said triangular section.  
   
   
       22 . A golf putter as set forth in  claim 21  further having a pair of weights mounted in said head, each said weight being mounted in an upper surface of a respective lobe.  
   
   
       23 . A golf putter as set forth in  claim 22  further having at least one recesses in an upper surface thereof, said recess being disposed symmetrically of said centerline.  
   
   
       24 . A golf putter as set forth in  claim 20  having a groove in an upper surface of said shoulder extending perpendicularly of said bore and parallel to said front face for alignment of said front face perpendicularly to an imaginary line extending from said front face to a cup.  
   
   
       25 . A golf putter as set forth in  claim 20  wherein said putter head has large moments of inertia about three primary axes.  
   
   
       26 . A golf putter as set forth in  claim 20  wherein said face faces upward when the putter is balanced in a horizontal manner.
