Abstract:
1. A golf driving range platform having: a base plate having a lower surface and an upper surface, the base plate lower surface being provided to rest on a ground; a lower wedge having a lower surface and an upper surface inclined relative to each other by a first predetermined angle, the lower wedge lower surface being disposed above said base plate upper surface and supported thereon, the lower wedge being rotatable relative to said base plate about a first rotation axis extending substantially perpendicular to the base plate upper surface; an upper wedge having a lower surface and an upper surface inclined relative to each other by a second predetermined angle, the upper wedge lower surface being disposed above said lower wedge upper surface and supported thereon, the upper wedge being rotatable relative to said base plate and said lower wedge; a top plate having a lower surface and an upper surface, the top plate lower surface disposed above said upper wedge upper surface and supported thereon, the upper wedge being rotatable relative to said top plate about a second rotation axis extending substantially perpendicular to the top plate lower surface; and a joint means connecting said top plate to said base plate such that the top plate is substantially not rotatable relative to the base plate, the top plate can tilt relative to the base plate, and the upper and lower wedges are rotatable relative to said top plate.
