发明名称 Golf swing practice platform
摘要 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.
