ABSTRACT:
A portable heliport adapted to be transported by a helicopter is described. The heliport includes a pair of deck extensions having foldable, extensible legs and which are hinged to a central deck supported by extensible legs. The deck extensions are folded and allowed to unfold by a winch which is detachable from the central deck and whose winch support also supports the deck extensions for transport by the helicopter. The extensible legs have threaded tubes telescoping in fixed tubes and quick releasable internally threaded, split clamps attached to the fixed tubes hold the threaded tubes in adjusted positions. The threaded tubes may be screwed into or out of the split clamps for fine adjustments. The legs on one side of the deck are longer than those on the opposite side so that, when the legs are all in contracted conditions, the port is in a condition adapted to a moderate slope site.
