Patent ID: 7625294

Claim:
An apparatus to improve a golf swing, comprising: a. a generally rectangular shaped plank having an upper surface and a lower surface, a pair of oppositely disposed lengthwise sides and a pair of oppositely disposed widthwise edges, and a longitudinal centerline; b. the lower surface of the generally rectangular shaped plank having a multiplicity of positioning markers including a first and second parallel row of positioning makers aligned along the lengthwise distance of the generally rectangular shaped plank, each positioning marker in a row spaced apart from an adjacent positioning marker by a given distance, the two rows of positioning markers respectively spaced away from a respective lengthwise side of the plank and also spaced apart from each other by a given distance, the lower surface also having a first pair of positioning markers adjacent one widthwise edge of the plank and a second pair of positioning markers adjacent an opposite widthwise edge of the plank, a respective positioning marker from the first pair aligned with a respective positioning marker from the second pair, the lower surface also having a third pair of positioning markers adjacent the longitudinal centerline of the plank and a fourth pair of positioning markers adjacent the longitudinal centerline of the plank, each of the positioning markers of the third and fourth pair aligned on opposite sides of the longitudinal centerline of the plank and also respectively aligned with a respective positioning marker of the third and fourth pair, all of the positioning markers acting as position reference locators on the plank; c. height adjustable risers having mating means which are attached to the plank at the location of the positioning markers, each of the height adjustable risers affixed over at least two respective positioning markers to produce different orientations when the apparatus is in use; d. a multiplicity of foot positioning templates with a given one template attachable to the upper surface of the plank for use at a given time, the multiplicity of foot positioning templates selected from the group consisting of full swing right handed, full swing left handed, pitch shot right handed, pitch shot left handed, chip shot right handed, chip shot left handed, closed stance right handed and open shot left handed, open stance right handed and closed stance left handed; and e. the positioning of the height adjustment risers in particular positioning markers combined with the use of selected foot positioning templates determining the type of golf swing being simulated, the nature of the height adjustment risers enabling the apparatus to be in a stable condition regardless of which positioning markers the height adjustment risers are placed into.
