<p>A golf driving range platform (20) having: a base plate (22) having a lower surface (21) and an upper surface (23), the base plate lower surface (21) being provided to rest on a ground; a lower wedge (26) having a lower surface (27) and an upper surface (28) inclined relative to each other by a first predetermined angle (29), the lower wedge lower surface (27) being disposed above said base plate upper surface (23) and supported thereon, the lower wedge (26) being rotatable relative to said base plate (22) about a first rotation axis (40) extending substantially perpendicular to the base plate upper surface (23); an upper wedge (30) having a lower surface (31) and an upper surface (32) inclined relative to each other by a second predetermined angle (33), the upper wedge lower surface (31) being disposed above said lower wedge upper surface (28) and supported thereon, the upper wedge (30) being rotatable relative to said base plate (22) and said lower wedge (26); a top plate (34) having a lower surface (35) and an upper surface (36), the top plate lower surface (35) disposed above said upper wedge upper surface (32) and supported thereon, the upper wedge (30) being rotatable relative to said top plate (34) about a second rotation axis (41) extending substantially perpendicular to the top plate lower surface (35); and a joint means (42) connecting said top plate (34) to said base plate (22) such that the top plate (34) is substantially not rotatable relative to the base plate (22), the top plate (34) can tilt relative to the base plate (22), and the upper and lower wedges (30, 26) are rotatable relative to said top plate.</p> |
