Abstract
A rescue basket structure to be suspended from a helicopter winch cable comprises a cruciform-like suspension frame and a collapsible rectangular basket-like container suspended by cables from the frame. The suspension frame has tail fins to stabilize the structure when it is airborne and the cable configuration is designed to impart a scooping action to the container when it is lowered into water to facilitate access thereto by a person being rescued or an object being recovered. The basket-like container may also be partially covered over its base and may trail a sea anchor to enhance the scooping action.
Claims15
Apparatus for suspension from a helicopter and the like for use in rescue and recovery operations, the apparatus comprising a suspension frme, means for attaching the frame to a helicopter winch cable and the like, means for suspending a basket-like container from the frame, and fin means or the frame for stabilizing the apparatus when airborne, wherein the suspension frame includes an elongate frame member, and a cross bar, the means suspending the container comprises cables connected at opposite ends of the elongate member and cross bar, the means for attaching the frame to a helicopter winch cable or the like is located substantially centrally of the elongate member, and the fin means is located at one end of the elongate member.
