Planar-parallactic golf alignment aide

Abstract

A Planar-Parallactic Golf Alignment Aide is disclosed. Also disclosed is a device that provides the golfer with a planar alignment sight line for aligning the club face with the target. The invention further provides the golfer with a parallactic alignment sight line for placing his or her head in the proper and repeatable position in order to eliminate unintentional stance variations. The aide may be incorporated within the club head and operate by aligning an aperture or line with the projected image of that aperture or line to use the phenomena of parallax for head alignment. The aperture or line is formed in the top of a dome, and the projected image then appears on a projection surface below the dome. The device may either be an attachment for a conventional club head, or may incorporated into the head itself.

What is claimed is:  
     
         1 . A golf club, comprising: 
 a head defined by a face and a top surface;    an alignment assembly comprising a dome attached to said top surface.    
     
     
         2 . The club of  claim 1 , wherein said dome is further defined by a top surface, said top surface having a slot formed therein.  
     
     
         3 . The club of  claim 2 , wherein said slot is aligned along a line that is generally perpendicular to said face.  
     
     
         4 . The club of  claim 3 , wherein said dome is further defined by a void formed within said dome, said void bounded at its top by said top surface and at its bottom by a projection surface.  
     
     
         5 . The club of  claim 4 , wherein said projection surface and said slot are cooperatively arranged whereby incident light upon said slot creates a projected image of a line on said projection surface.  
     
     
         6 . The club of  claim 5 , wherein said projection surface, slot and said projected image are oriented whereby said projected image is aligned with said slot along a parallactic alignment sight line.  
     
     
         7 . The club of  claim 1 , wherein said dome is further defined by a top surface, said top surface having at least a pair of apertures formed therethrough.  
     
     
         8 . The club of  claim 7 , wherein said apertures are aligned along a line that is generally perpendicular to said face.  
     
     
         9 . The club of  claim 1 , wherein said dome is defined by a top surface, said dome top surface being said club head top surface.  
     
     
         10 . The club of  claim 9 , wherein said top surface is defined by at least a pair of apertures formed therethrough, said apertures aligned in a line that is generally perpendicular to said face.  
     
     
         11 . The club of  claim 9 , wherein said top surface is defined by a slot formed therethrough, said slot defining a line that is generally perpendicular to said face.  
     
     
         12 . An alignment assembly for attachment to a top surface of a golf club head, comprising: 
 a dome defined by a top surface and a projection surface, said dome further defined by a slot formed in said top surface.    
     
     
         13 . The assembly of  claim 12 , wherein said top surface further comprises at least one darkened portion of said surface adjacent to said slot.  
     
     
         14 . The assembly of  claim 13 , wherein said projection surface further comprises a lightened portion.  
     
     
         15 . A golf club having head defining a face and a top surface, the head comprising: 
 parallactic alignment means for defining a parallactic alignment sight line; and    planar alignment means for defining a planar alignment sight line.    
     
     
         16 . The club of  claim 15 , wherein said planar alignment means comprises a slot associated with said club oriented perpendicular to said face.  
     
     
         17 . The club of  claim 16 , wherein said parallactic alignment means comprises a dome attached to said head top surface, said slot formed in said dome.  
     
     
         18 . The club of  claim 17 , wherein said parallactic alignment means comprises a projection surface associated with said head top surface opposite to said slot.  
     
     
         19 . The club of  claim 18 , wherein said dome comprises a clear dome having a pair of darkened portions adjacent to said slot.  
     
     
         20 . The club of  claim 19 , wherein said projection surface further comprises a lightened portion generally opposite to said slot.
