Novel curvilinear golf club-head

Abstract

The present invention provides a novel visual golf club-head curvilinear path indicator and method of use. Specifically, the present invention provides a visual golf club-head curvilinear path guide in the form of one or more alignment lines or markings on putters and other club-heads that are curvilinear (instead of linear) and that curve toward the golfer's body as he or she stands at address. The curvilinear line (or lines) and/or shape (or shapes) are intended to provide the golfer with a visual reminder to move the club-head back and through along a curvilinear path.

       6 . The golf club putter head as claimed in  claim 1 , further comprising one or more curvilinear indicia on an upper surface of the central body which curve toward the body of the user when standing at address. 
   
   
       7 . The golf club putter head as claimed in  claim 1 , further comprising a linear alignment indicia located on the upper surface of the central body. 
   
   
       8 . The golf club putter head as claimed in  claim 6 , wherein the curvilinear indicia are of the same or different lengths, of the same or different colors, of the same or different widths. 
   
   
       9 . The golf club putter head as claimed in  claim 6 , wherein the curvilinear indicia are selected from one or more of an arc, a compound arc, a curved representation of dots, a curved representation of dashes, a curved representation of triangles, a curved representation of circles or partial circles, a curved representation of spheres, a curved representation of arrows, or a curved representation of geometric shapes, all that arc toward the body of the user while standing at address. 
   
   
       10 . The golf club putter head as claimed in  claim 6  wherein the curvilinear indicia curve open toward the user in different degrees or have different radii of curvature. 
   
   
       11 . The golf club as claimed in  claim 6 , wherein the curvilinear indicia may be formed by one or more of a raised portion, a sunken portion, an otherwise contoured portion able to visualized by the user. 
   
   
       12 . The golf club as claimed in  claim 6 , wherein the curvilinear indicia are adjustable or removable. 
   
   
       13 . A golf club putter head, comprising:
 a central body having a heel end, a toe end, a front, a back, wherein the central body comprises one or more curvilinear indicia that curve toward the body of the user when standing at address and wherein the central body excludes any curvilinear indicia that curve away from the body of the user.   
   
   
       14 . The golf club putter head of  claim 1  wherein the curvilinear indicia extends as an arc having a single radius of curvature along all or part of the depth of the putter-head. 
   
   
       15 . The golf club putter head of  claim 13  wherein the curvilinear indicia begins at or near the front of the central body. 
   
   
       16 . The golf club putter head of  claim 13  wherein the curvilinear indicia ends at or near the back of the central body. 
   
   
       17 . The golf club putter head of  claim 13  wherein the curvilinear indicia begins at any point along the central body and extends along all or part of the depth of the putter-head. 
   
   
       18 . The golf club putter head as claimed in  claim 13 , further comprising a linear alignment indicia located on the upper surface of the central body. 
   
   
       19 . The golf club putter head as claimed in  claim 13 , wherein the curvilinear indicia are of the same or different lengths, of the same or different colors, of the same or different widths. 
   
   
       20 . The golf club putter head as claimed in  claim 13 , wherein the curvilinear indicia are selected from one or more of an arc, a compound arc, a curved representation of dots, a curved representation of dashes, a curved representation of triangles, a curved representation of circles or partial circles, a curved representation of spheres, a curved representation of arrows, or a curved representation of geometric shapes, all that arc toward the body of the user while standing at address. 
   
   
       21 . The golf club putter head as claimed in  claim 13  wherein the curvilinear indicia curve open toward the user in different degrees or have different radii of curvature. 
   
   
       22 . The golf club as claimed in  claim 13 , wherein the curvilinear indicia may be formed by one or more of a raised portion, a sunken portion, an otherwise contoured portion able to visualized by the user. 
   
   
       23 . The golf club as claimed in  claim 13 , wherein the curvilinear indicia are adjustable or removable. 
   
   
       24 . A golf club head to encourage a curvilinear swing path, comprising:
 a central having a heel end, a toe end, a front, a back, wherein all or part of the central body is of a curvilinear shape that curves toward the body of the user when standing at address.   
   
   
       25 . The golf club head of  claim 24  wherein the curvilinear shape extends as an arc having a single radius of curvature along all or part of the depth of the golf club head.
