Abstract
Abstract A main frame for support from the ground is provided and a pair of right and left foot support plates are mounted on the frame in spaced side-by-side relation. The first foot plate is supported from the frame for shifting toward and away from the left foot plate and the latter is supported from the frame for oscillation about a horizontal axis extending normal to a path extending between the plates. A pair of signal generator actuating switches are operatively associated with the frame and the left foot support plate for indicating predetermined positions of opposite angular displacement of the left foot support plate relative to the frame and the right and left foot support plates include toe guides for positioning the toe of the associated golfer's shoes. In addition, the left foot plate includes a heel guide for positioning the heel of the left shoe of the golfer. The frame also adjustably supports an elongated guide support outwardly therefrom in position generally paralleling the aforementioned path and for lateral adjustment toward and away from the frame and the support includes structure for supporting a golf ball therefrom.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
199 words
A golf swing practice device including a base adapted for support from a horizontal surface, a pair of foot support platforms supported from said base in side-by-side spaced relation, and for adjustable shifting of at least one of said platforms relative to said base toward and away from the other platform, a first of said platforms being supported from said base for oscillation relative thereto about a horizontal axis disposed generally normal to a line extending between said platforms and signal means operatively associated with at least said first platform and base for rendering a signal should said first platform exceed at least one position of a pair of opposite predetermined opposite positions of oscillation relative to said base and including an elongated support generally paralleling said line and means operatively connecting said support with said base for selected lateral shifting toward and away from said platforms with said support generally horizontally aligned with said platforms, said support including golf ball means for support of a golf ball in stationary position thereon, wherein said elongated support includes a longitudinally extending guide, said golf ball support means comprising an upstanding tee supported from said guide for slidably adjustable positioning therealong.
Claim 2
Dependent Claim
199 words
A golf swing practice device including a base adapted for support from a horizontal surface, a pair of foot support platforms supported from said base in side-by-side spaced relation, and for adjustable shifting of at least one of said platforms relative to said base toward and away from the other platform, a first of said platforms being supported from said base for oscillation relative thereto about a horizontal axis disposed generally normal to a line extending between said platforms and signal means operatively associated with at least said first platform and base for rendering a signal should said first platform exceed at least one position of a pair of opposite predetermined opposite positions of oscillation relative to said base and including an elongated support generally paralleling said line and means operatively connecting said support with said base for selected lateral shifting toward and away from said platforms with said support generally horizontally aligned with said platforms, said support including golf ball means for support of a golf ball in stationary position thereon, wherein said elongated support includes a longitudinally extending guide, said golf ball support means comprising an upstanding tee supported from said guide for slidably adjustable positioning therealong.
Claim 3
Dependent Claim
