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.

Claims

1. In a portable heliport,

a central deck,

winch means including a central support and a pair of pads,

means detachably securing said central support of the winch means to the central deck,

deck extension means foldable into engagement with the pads,

means mounting the deck extension means foldably on the central deck,

and cable means connecting the winch means to the deck extension means.

2. The portable heliport of claim 1 wherein the winch means includes handle means positioned above the central deck in a position operable by a helicopter pilot to lower the deck extension means.

3. In a portable heliport,

a central deck,

a plurality of deck extensions,

hinge means connecting the deck extensions to the central deck,

means for supporting the heliport by a helicopter for transport,

folding leg means connected to the deck extensions,

and second leg means connected to the central deck,

some of the leg means being telescopic,

the telescopic leg means including fixed tubes, extensible tubes telescopic relative to the fixed tubes, and releasable split clamp means for holding the extensible tubes in adjusted positions relative to the fixed tubes,

the extensible tubes having threaded portions and being rotatable,

the split clamp means having thread segments for engaging the threaded portions.

4. In a portable heliport

deck means,

and leg means for supporting the deck means and including at least one extensible leg,

said extensible leg including a fixed leg section secured to the deck means, an extensible leg section telescopic relative to the fixed leg section, and quickly releasable locking means comprising a split clamp for holding the extensible leg section in a plurality of extended positions relative to the fixed leg section,

the split clamp including a pair of arms, a pair of opposed thread segments on the arms, and quick release actuating means for opening and closing the arms relative to the extensible leg section,

the extensible leg section having an external thread adapted to interlock with the thread segments when the arms are closed.

5. The portable heliport of claim 4 wherein the extensible leg section is rotatable relative to the clamp to screw the extensible leg section further into and farther out of the clamp.

6. The portable heliport of claim 4 wherein the quick release actuating means includes a pin secured to one arm and a movable slotted member on the other arm.
