A weatherproof cover for an opening in a cargo container comprising a flexible curtain secured across the top of the opening by a header, rails secured to the sides and bottom of the opening with flanges extending away from the opening, and a cable in a tunnel sewed into the periphery of the curtain which overhangs the rail flanges. One end of the cable is secured to the header on one side, and the other end is secured to a sheave in a ratchet assembly on the other side of the header. The ratchet assembly is used to pull the cable tight against the rails under their flanges. A fitting on the curtain comprised of a hub and a sheave is provided at each lower corner for the cable. The hubs of the curtain fittings are placed over posts on gussets at the lower corners of the container opening. Diagonal cables in tunnels sewn in back of the curtain reinforce the curtain and the container itself.
A cover for an opening in a cargo container comprising a curtain of flexible material, means for securing said curtain to said container along one side and on the outside of said opening, flanging means rigidly secured to said container for providing a flange around said opening substantially uninterrupted from one end to the other of said curtain securing means, said flange standing out away from said container and extending in a direction away from said opening, thereby providing a channel from substantially one end to the other of said curtain securing means, said curtain being of a size and shape to overhang said flange, and having along its edge a tunnel running substantially uninterrupted from one end to the other of said curtain securing means, a cable inserted in said curtain tunnel, said cable having one end anchored at said one end of said curtain securing means, tensioning means anchored to said container at the other end of said curtain securing means for pulling said cable taut in said channel, and releasable latching means for latching said tensioning means with tension on said cable.
A flexible cover for an opening in a cargo container comprising a curtain of flexible material, a cable, releasable cable tensioning means, means for fastening said curtain to an outside wall of said container along one side of said opening, and flanging means around said opening from one end of said curtain fastening means to the other for providing a flange which stands away from said container and turns back from the outer edge of said opening in a direction away from said opening in a plane substantially parallel to said outside wall, said cable extending around said curtain through a substantially continuous tunnel along the periphery thereof from one end of said curtain fastening means to the other, one end of said cable being securely fixed at the one end of said curtain fastening means, and the other end of said cable being secured at the other end of said curtain fastening means by said cable tensioning means, said curtain being shaped to fit over the opening with enough overlap for the cable to fit over said flange so that when the curtain is placed in a covering position over said opening with said cable over said flange, and the cable is pulled taut by said releasable tensioning means, said curtain is sealed against said flange around the container opening.
