Abstract
Abstract A training device adapted for improving a golfer''s swing comprises a wing-shaped member attached to the shaft of a golf club adjacent to the head thereof. The member has substantial air drag inducing surface areas formed thereon with a preselected maximum aspect ratio for initially impeding club head speed and for gradually permitting such speed to increase when the club head enters the hitting zone.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
142 words
A golf training device including an attachment to a golf club to improve a golfer''s swing comprising: a one-piece member having two wing portions extending away from each other in opposite directions, substantial air drag inducing surface area means formed on said two wing portions and positioned with respect to said golf club so as to have a variable effective aspect ratio for creating and encountering turbulent air resistance for impeding club head speed during a golfer''s downswing and for permitting such speed to gradually increase to a maximum velocity when a club head enters a hitting zone, and fastening means positioned between and connected to said wing portions for attaching said wing portions directly to the shaft of a golf club for selectively orientating said wing portions on said shaft for inducing a hook or fade when a ball is hit.
