Abstract
An improved apparatus for golf practice formed from two coaxial wedge-shaped structures, one above the other and rotatable relative to each other and with respect to an underlying supporting platform to provide tilt and tilt direction for practicing golf swings on up slope, down slope and cross slope lies, to simulate the various slope and slope directions of a real golf course. The lower wedge-shaped structure acts as a solid support for the upper wedge-shaped structure and rotation of the upper wedge-shaped structure may result in the tilt of the upper surface of the upper wedge-shaped structures over a continuous range from zero degrees up to the total of the angles of the two wedge-shaped structures. The direction of the tilt angle of the upper surface of the upper wedge-shaped structure relative to an underlying planar base can then be varied by rotating the two structures together about a vertical axis. The upper surface of the upper wedge-shaped structure is preferably covered with a simulated grass mat. The wedge-shaped structures may be either solid or formed from an assembly of structural elements that are arranged into a wedge shape and may be rotated manually and locked in a selected position, or each may be driven to such selected position by a powered drive assembly disposed either internally or externally on the structure itself.
