An endwise pushdown guide and lateral restraint fitting for cargo having a base adapted to be secured to an aircraft subfloor. The base supports to a pair of parallel pivot pins and pivotally secured on each pin is a respective blade normally extending in an upright position. Each blade is supported by a pair of lugs through which a respective pivot pin extends, the pin for each blade being remote therefrom to provide a moment arm from the pivot to the blade. The blades are parallel and have respective ramp surfaces, tapering toward the direction from which cargo may be moved along an aircraft floor. Thus, when a cargo container is moved against one tapering surface the horizontal force thereof has a downward component which acts on the tapering surface and the moment arm of that blade to cause the blade to pivot downwardly under the container so that it can be moved past what would otherwise be a restricting blade, the blades being adapted to restrict cargo on their lateral surfaces outwardly of the supporting base and pivots.

An endwise pushdown guide and lateral restraint fitting for cargo, comprising: a base; two juxtaposed laterally spaced generally upright blades for laterally restraining cargo, said blades being pivotally mounted on said base; said base supporting two laterally spaced juxtaposed pivot pins; each blade being mounted to pivot on a respective pivot pin remote therefrom; a coil spring to normally retractably secure said blades in an upper pivotal position in a direction upwardly from said base, said spring having one end associated with one blade and the other end associated with the other blade so as to bias said blades toward and in said upper pivotal position; each respective blade being pivotal toward said base from said upper position when a force acting on and through a respective blade is applied to said coil spring through the association of the blade and spring; and means on each respective blade to receive said force and to direct a downward component of said force in a direction transverse to the force and downwardly toward said base to pivot the respective blade toward the base and below the force source.
