Cargo platform assembly mounted to a helicopter
First Claim
1. For use on a helicopter having a pair of oppositely disposed parallel skid tubes extending longitudinally below a helicopter fuselage, a cargo platform assembly adapted for attachment to at least one of the skid tubes and the helicopter fuselage, said assembly comprising:
- a frame structure including a plurality of substantially rigid, sufficiently strong elongate tubes interconnecting with one another forming a longitudinal portion, a transverse portion, and a railing extending at least partially around an outer perimeter of said frame,said elongate tubes include metal tubes having a rectangular cross-sectional configuration,said metal tubes being of sufficient strength to support a substantial load placed on a support surface,said support surface mounted in substantially covering relation to an upper side of said frame structure defining a platform, mounting means for mounting said frame structure to at least one of the skid tubes,said mounting means structured to permit lateral movement of the skid tube with respect to said frame structure,platform support means connecting in supporting relation between said frame structure and the fuselage of the helicopter,a cross bar mounted to and extending transversely across a cabin floor of the helicopter,said cross bar including a channel configuration adapted to fit in mounting, covering relation to a transversely extended rib on the cabin floor, each opposite end of said cross bar further being dimensioned and configured to adaptively receive one end of an outboard support structure for connection thereto as a means for added support to the platform assembly,said cross bar including a plurality of connecting pins each being adapted to pass through said cross bar and said transverse rib for securing said cross bar thereto, andsaid cross bar includes two telescopically extended portions structured and configured to permit varied adjustment of the length of said cross bar.

Abstract
A cargo and work platform assembly adapted to be mounted to at least one of two longitudinally extending skid tubes beneath a helicopter fuselage wherein a plurality of support struts including inboard support struts and outboard support struts extend in supporting, connecting relation between the platform and the fuselage. In a preferred embodiment, the platform assembly includes two independent platforms separably mounted to one of the two longitudinal skid tubes in such a manner as to allow lateral displacement of the skid tubes upon landing or takeoff.
