Patent ID: 8074818

Claim:
A container adapted to be transported by air or surface transportation, said container comprising: a base forming a pocket and having a generally flat bottom surface adapted to engage rollers of an aircraft cargo handling system for air transportation of said container, said base being located at the bottom of said container; a corner post including a first end, a second end and a central axis, said pocket located below said first end of said corner post; a lower movable corner block having a plurality of apertures and a bottom surface, said pocket adapted to receive said movable corner block, said lower movable corner block located below said first end of said corner post and movably coupled to said corner post for selective movement with respect to said base along a translational axis generally transverse to said bottom surface of said base between a retracted air transport position and an extended surface transport position, said lower movable corner block being located at least partially within said pocket when said lower movable corner block is in said retracted air transport position and when said lower movable corner block is in said extended surface transport position, said bottom surface of said lower movable corner block being located outwardly from said bottom surface of said base when said lower movable corner block is located in said extended surface transport position such that said container is configured for surface transportation, said bottom surface of said lower movable corner block being located generally coplanar with or inwardly from said bottom surface of said base when said lower movable corner block is located in said retracted air transport position such that said container is configured for air transportation wherein said bottom surface of said base is adapted to engage the rollers of an aircraft cargo handling system; and an adjustment mechanism adapted to selectively position said lower movable corner block with respect to said base, said adjustment mechanism adapted to selectively move said bottom surface of said lower movable corner block along said translational axis toward said bottom surface of said base when said lower movable corner block is moved from said extended surface transport position toward said retracted air transport position, said adjustment mechanism adapted to selectively move said bottom surface of said lower movable corner block along said translational axis away from said bottom surface of said base when said lower movable corner block is moved toward said extended surface transport position.
