Patent ID: 7845113

Claim:
A liftable support platform adapted for the dual role of supporting a layer of natural turf or a layer of artificial turf and infill above a foundation, the platform comprising: a structure moulded in foamed plastics in two halves joined to form a square or rectangle, the join being about a diagonal, the sides of the structure being between 2250 and 2400 mm in length, the structure further having a) a closed planar top surface adapted to support the layer of turf above the foundation, said top surface being provided with specifically positioned drainage holes adapted for draining water which has drained through the layer of turf thereabove, b) a latticework which supports the top surface and hence the layer of turf, said latticework having mutually perpendicular walls defining a flexible open foundation engaging planar base, and c) a pair of elongate spaced parallel wall channels extending across each side of the planar base of the latticework to facilitate forklift tine entry therein and lifting of the support platform and layer of turf; edge retainers fixed to the sides of the structure, the edge retainers having an upper edge above the top surface of the structure to define an enclosure to prevent escape of the layer of turf from the top surface; a slot across adjacent edges of each corner of the structure; and members which are accommodated in said slots and which are adapted to extend and join the structure to similar adjacent structures in abutting contact and to prevent each corner of the structure from arching upwardly in use relative to the associated corners of the similar adjacent structures.
