Abstract

Unlike earlier visual alignment aids, the present devices and methods may transfer focus away from a central sight line to a plurality of multicolored auxiliary sight lines. The multicolored sight lines are typically brightly colored to maintain the player's focus and help avoid head movement during initiation of the swing. Further, in some embodiments, the central and/or auxiliary sight lines are dashed, with the dashes either aligned or offset from one another. In this way, hyper-acuity becomes two-dimensional with sight lines running in a first dimension (e.g., from face-to-back, when markings are on the crown, or top-to-bottom, when markings are on the face) and cross lines, made up of inter-sight line dashes, running in a second dimension (e.g., from heal-to-toe).

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A golf club comprising:
 a shaft connected to a head, the head having a planar front face;   a plurality of parallel grooves in the planar front face running from a heal to a toe of the head, the plurality of parallel grooves and material between the parallel grooves defining a grooved area; and   a plurality of sight lines within the grooved area;   wherein at least one of the sight lines is multicolored.   
     
     
         2 . The golf club of  claim 1 , wherein each of the sight lines is oriented perpendicular to the plurality of parallel grooves. 
     
     
         3 . The golf club of  claim 1 , wherein each of the sight lines is disposed on the material between the parallel grooves. 
     
     
         4 . The golf club of  claim 3 , wherein each of the sight lines is disposed in the parallel grooves. 
     
     
         5 . The golf club of  claim 4 , wherein each of the sight lines is at least partially or completely disposed on bottom surfaces of the parallel grooves. 
     
     
         6 . The golf club of  claim 1 , wherein each of the sight lines is disposed in the parallel grooves. 
     
     
         7 . The golf club of  claim 6 , wherein each of the sight lines is at least partially or completely disposed on bottom surfaces of the parallel grooves. 
     
     
         8 . The golf club of  claim 1 , wherein colors of the multicolored sight line(s) are spatially separate from one another. 
     
     
         9 . The golf club of  claim 1 , wherein the plurality of sight lines comprises a central line and at least two outer lines. 
     
     
         10 . The golf club of  claim 9 , wherein the outer lines have the same multicolored pattern. 
     
     
         11 . The golf club of  claim 1 , wherein the golf club is a wood, a driver, an iron, a wedge, a hybrid or a putter. 
     
     
         12 . A golf club comprising:
 a shaft connected to a head, the head having a planar front face;   a plurality of parallel grooves in the planar front face running from a heal to a toe of the head, the plurality of parallel grooves and material between the parallel grooves defining a grooved area; and   at least one sight line within the grooved area;   wherein the at least one of the sight line is multicolored.   
     
     
         13 . The golf club of  claim 12 , wherein the at least one sight line is oriented perpendicular to the plurality of parallel grooves. 
     
     
         14 . The golf club of  claim 12 , wherein the at least one sight line is disposed on the material between the parallel grooves. 
     
     
         15 . The golf club of  claim 14 , wherein the at least one sight line is disposed in the parallel grooves. 
     
     
         16 . The golf club of  claim 15 , wherein the at least one sight line is at least partially or completely disposed on bottom surfaces of the parallel grooves. 
     
     
         17 . The golf club of  claim 11 , wherein the at least one sight line is disposed in the parallel grooves. 
     
     
         18 . The golf club of  claim 17 , wherein the at least one sight line is at least partially or completely disposed on bottom surfaces of the parallel grooves. 
     
     
         19 . The golf club of  claim 11 , wherein colors of the multicolored sight line are spatially separate from one another. 
     
     
         20 . The golf club of  claim 11 , wherein the golf club is a wood, a driver, an iron, a wedge, a hybrid or a putter.
