Golf club head including alignment device
First Claim
1. A golf club head comprising:
- a ball striking face having a predetermined ball-striking location thereon for striking a ball;
said face defining a plane having a predetermined preferred vertical orientation and;
a bottom;
a top;
alignment means comprising;
an alignment device comprising;
a sight having a center and comprisinga first centered figure having a perimeter and a color or pattern;
a first concentric ring surrounding said first centered figure;
said first concentric ring being transparent;
a second concentric ring having a pattern or color and an inside perimeter radially outwardly spaced from the perimeter of said first centered figure and an outside perimeter; and
a third concentric ring surrounding said second concentric ring;
said third concentric ring being transparent; and
a target disposed below said sight and separated therefrom by a transparent medium;
said target having a center and comprising;
a second centered figure having a perimeter larger than the perimeter of said first centered figure and distinguishable in color or pattern from said first centered figure; and
a fourth concentric ring having an inside perimeter smaller than said inside perimeter of said second concentric ring and an outside perimeter larger than said outside perimeter of said second concentric ring and distinguishable in color or pattern from said second concentric ring; and
attaching means for attaching said alignment device to said head such that said striking face is at the preferred vertical orientation when the center of said sight is vertically aligned with the center of said target such that the resulting vertical sight picture includes at least four concentric colored or patterned rings.

Abstract
A golf club head includes a transparent cylinder with a sight on top and target on the bottom for indicating to the golfer when the club head is level and on line. An exemplary sight includes a centered disk surrounded by concentric rings; some rings being transparent. The target includes a larger central disk sounded by concentric rings of contrasting color or pattern. At the preferred club orientation, the center of the sight is vertically aligned with the center of the target and the vertical sight picture includes at least four concentric colored or patterned rings. In a second embodiment, the sight and target each include a swing stripe in the swing direction. The relative location of the sight and target centers and swing stripes show the golfer the position of the club head relative to the ball and aid in swing smoothness.
