Estimating the term…
The door sill of a cargo loading and unloading opening in an aircraft body is protected against damage by a cover plate that is hinged to the loading floor alongside the door opening to be tiltable outwardly to cover the sill when in the operative position. The outwardly pointing edge of the cover plate is supported by a support linkage, including a support link or section and a tie rod or bracing link, which are pivoted to the cover plate and to each other, so that the plate and its support linkage may be tilted into a recessed position in which the plate with its support linkage extends substantially in parallel and close to the door or gate that closes the cargo opening, thereby using very little space in the stowed condition.
A device for covering and protecting a door sill of an opening leading into an aircraft body, comprising a cover plate, at least one hinge connecting an inner first edge of said cover plate to a floor of the aircraft, and a support linkage for supporting an outward second edge of said cover plate, said support linkage including a support section (10), a bracing section (13), a first journal (11) connecting said outward second edge of said cover plate to said support section, a second journal (15) connecting said bracing section to said cover plate, and a third journal (14) connecting said bracing section (13) to said support section (10), said support section (10) comprising a foot (18) for releasably cooperating with a holding member (18A) secured to said aircraft body, and wherein a spacing is provided between said second journal (15) and said at least one hinge, said spacing being just sufficient to permit folding said support linkage toward a back side of said cover plate when said cover plate is in a stowed position.
