Abstract
Abstract An extended unit load device for loading cargo into the lower decks of aircraft which comprises a standard pallet having a peripheral seat track and an inclined side support adapted to be pivotably and removably inserted in the track. The inclined side support may be mounted upon an attachment leg which comprises an engagement foot which engages the seat track and pivots in such a fashion as to lift the inclined side support to the inclined position. The inclined side support preferably comprises a sandwich of corrugated metal filled with polyurethane foam therebetween. Reinforcing rods may be inserted at periodic intervals along the length thereof. Cables affixed at one end thereof to each side of the inclined side support and at the other end thereof to the seat track serve to retain the inclined side support in the inclined position.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
193 words
An extended unit load device comprising: a standard pallet having a peripheral seat track, disposed in its operative orientation in a horizontal plane, said peripheral seat track defining in cross section a recess and first and second edge members partially overlapping said recess; an inclined side support adapted to be removably and pivotably inserted in the track and oriented in an inclined position, said inclined side support including an attachment leg having an elongate upstanding portion having a generally vertical operative orientation, perpendicular to the plane of said standard pallet, and a foot portion including a toe portion extending in operative orientation sideways in cross section and underlying said first edge member and a heel portion extending in operative orientation sideways in cross section and engaging said second edge member; a first cable attached at one end thereof to one side of the inclined side support; and a second cable attached at one end thereof to the other side of the inclined side support; said first and second cables being anchored at the other ends thereof to the peripheral seat track so as to retain the inclined side support in the inclined position.
Claim 2
Dependent Claim
193 words
An extended unit load device comprising: a standard pallet having a peripheral seat track, disposed in its operative orientation in a horizontal plane, said peripheral seat track defining in cross section a recess and first and second edge members partially overlapping said recess; an inclined side support adapted to be removably and pivotably inserted in the track and oriented in an inclined position, said inclined side support including an attachment leg having an elongate upstanding portion having a generally vertical operative orientation, perpendicular to the plane of said standard pallet, and a foot portion including a toe portion extending in operative orientation sideways in cross section and underlying said first edge member and a heel portion extending in operative orientation sideways in cross section and engaging said second edge member; a first cable attached at one end thereof to one side of the inclined side support; and a second cable attached at one end thereof to the other side of the inclined side support; said first and second cables being anchored at the other ends thereof to the peripheral seat track so as to retain the inclined side support in the inclined position.
Claim 3
Dependent Claim
36 words
An extended unit loading device according to claim 1 and wherein said an attachment leg is affixed to the inclined side support and is adapted to removably and pivotably engage the seat track of the pallet.
Claim 4
Dependent Claim
162 words
An extended unit load device comprising: a standard pallet having a peripheral seat track, disposed in its operative orientation in a horizontal plane, said peripheral seat track defining in cross section a recess and first and second edge members partially overlapping said recess; an inclined side support; an attachment leg affixed to the inclined side support which is adapted to be removably inserted in the track and pivoted so as to lift the inclined side support to an inclined position, said attachment leg having a foot portion including a toe portion extending in operative orientation sideways in cross section and underlying said first edge member and a heel portion extending in operative orientation sideways in cross section and engaging said second edge member and first and second cables attached at one end thereof to each side of the inclined side support and at the other end thereof to the track so as to retain the inclined side support in the inclined position.
Claim 5
Dependent Claim
162 words
An extended unit load device comprising: a standard pallet having a peripheral seat track, disposed in its operative orientation in a horizontal plane, said peripheral seat track defining in cross section a recess and first and second edge members partially overlapping said recess; an inclined side support; an attachment leg affixed to the inclined side support which is adapted to be removably inserted in the track and pivoted so as to lift the inclined side support to an inclined position, said attachment leg having a foot portion including a toe portion extending in operative orientation sideways in cross section and underlying said first edge member and a heel portion extending in operative orientation sideways in cross section and engaging said second edge member and first and second cables attached at one end thereof to each side of the inclined side support and at the other end thereof to the track so as to retain the inclined side support in the inclined position.
Claim 6
Dependent Claim
22 words
An extended unit load device according to claim 3 and wherein the inclined position ranges from 0° to 45° from the horizontal.
Claim 7
Dependent Claim
26 words
A device according to claim 3 and wherein the inclined side support comprises a sandwich of two sheets of corrugated material filled with polyurethane foam therebetween.
Claim 8
Dependent Claim
