Abstract
Abstract A device to aid golfers in perfecting their golf swing during putting, chipping, driving and other usual golf situations. It provides a swing track comprising a pair of parallel spaced rails, rotatably mounted to a bracket, so as to be offset from the base surface. This track defines the preferred swing trajectory in the vicinity of ball contact. Faulty swings outside of such trajectory will touch one of the rails, imparting motion to the track. This rotation of the track both indicates the faulty swing and suggests the correction needed.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
112 words
A golf swing practice device comprising a pair of rails; a pair of crossed bracket means, securely connected to said rails near one end thereof by connecting means to maintain said rails spaced laterally apart in a constant parallel relationship and allow the head of a golf club to be swung therebetween; and a base, connected to said crossed bracket means at the intersection point thereof by a shouldered fastening means so as to promote free rotation of said rails about said base and including near the extremities of said base feet means, enabling the connection of said base to a stationary surface and the offset of said base from said surface.
