Abstract
Abstract A putter uses an angled mirrored upper club surface with a deeply scribed and pigment filled line to act as a sighting device. In one embodiment, a clear plastic block has a bottom surface coated with a highly reflective coating. A pair of lines are scribed on upper and lower surfaces of the block and must be aligned while the target is sighted in the mirrored surface. Other embodiments utilize deep grooves formed in the top of a mirrored or unmirrored club surface.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
129 words
A golf club comprising: a shaft; a grip region formed on said shaft; and a golf ball striking head attached to said shaft, said head including a striking surface portion and an upwardly sloped planar extension portion extending rearwardly of the head from an area proximate to said striking surface portion, said extension portion including a first mirrored surface with sighting means centrally positioned thereon, said sighting means including a groove cut into said first mirrored surface, said groove having darkened sidewalls so as to form a contrast between said first mirrored surface and said groove, and further wherein said head includes a second mirrored surface disposed proximate said groove for reflecting light through said groove whereby said groove is thoroughly illuminated during a use of said golf club.
Claim 2
Dependent Claim
129 words
A golf club comprising: a shaft; a grip region formed on said shaft; and a golf ball striking head attached to said shaft, said head including a striking surface portion and an upwardly sloped planar extension portion extending rearwardly of the head from an area proximate to said striking surface portion, said extension portion including a first mirrored surface with sighting means centrally positioned thereon, said sighting means including a groove cut into said first mirrored surface, said groove having darkened sidewalls so as to form a contrast between said first mirrored surface and said groove, and further wherein said head includes a second mirrored surface disposed proximate said groove for reflecting light through said groove whereby said groove is thoroughly illuminated during a use of said golf club.
Claim 3
Dependent Claim
17 words
The golf club of claim 1, wherein said sighting means includes a pair of spaced parallel edges.
Claim 4
Dependent Claim
21 words
The golf club of claim 2 wherein said parallel edges are formed in upper and lower surfaces of said extension portion.
Claim 5
Dependent Claim
41 words
The golf club as defined in claim 1, wherein said first mirrored surface portion extends to an edge of said striking surface so that a top portion of said golf ball to be struck is reflected in said first mirrored surface.
Claim 6
Dependent Claim
157 words
A golf club comprising: a shaft; a grip region formed on said shaft; and a golf ball striking head attached to said shaft, said head including a striking surface portion and an upwardly sloped planar portion forming a first extension, said first extension extending rearwardly of said head from an area proximate to said striking surface portion, said first extension including a first mirrored surface with sighting means centrally positioned thereon, said sighting means including a groove cut into said first mirrored surface and extending completely through said first extension, a group engaging portion extending rearwardly from said head forming a second extension, said second extension being positioned in an underlying relationship to said first extension and having a second mirrored surface on a topmost portion thereof, so as to permit a reflection of light from said second mirrored surface upwardly through said groove to effectively illuminate said groove to facilitate an effective use of sighting means.
Claim 7
Dependent Claim
157 words
A golf club comprising: a shaft; a grip region formed on said shaft; and a golf ball striking head attached to said shaft, said head including a striking surface portion and an upwardly sloped planar portion forming a first extension, said first extension extending rearwardly of said head from an area proximate to said striking surface portion, said first extension including a first mirrored surface with sighting means centrally positioned thereon, said sighting means including a groove cut into said first mirrored surface and extending completely through said first extension, a group engaging portion extending rearwardly from said head forming a second extension, said second extension being positioned in an underlying relationship to said first extension and having a second mirrored surface on a topmost portion thereof, so as to permit a reflection of light from said second mirrored surface upwardly through said groove to effectively illuminate said groove to facilitate an effective use of sighting means.
