Abstract: To secure containers on the floor of the cargo area of an aircraft, latches are known that comprise a frame and at least one latch hook, which is mounted on the frame so that it can pivot about an axle from a retracted resting position into an upright operating position. If due to inattentiveness of the service personnel the latch hook is left in its operating position and a container strikes against it while it is in this position, the result is often destruction of the floor structure. It is proposed to provide a safety device that allows the latch to be deflected out of the way when it is subjected to a predetermined overload in a direction parallel to the floor of the cargo area.

Abstract: A plurality of vertical rod assemblies restrain the movement of cargo during transport on a floor of a carrier having source of fluid which is at about atmospheric pressure while the carrier is being loaded and which is pressurized after loading, e.g., a trailer having wheels with brakes which are actuated by a pressurized air line. Each vertical rod assembly contains a rod which remains flush with the floor on which the cargo is loaded when the fluid source is not pressurized. When the fluid source is pressurized, each rod rises from openings in the floor at locations adjacent the cargo. Each rod is attached to a piston in a cylinder which moves up and down in response to the application and release of pressure.

Abstract: A guide rail and support assembly for use in an aircraft cargo compartment for guiding cargo containers being transported by the aircraft cargo container transportation system uses a four bar mechanism to allow the guide rail to be lowered to accommodate wide cargo containers.
