摘要： A multi-level rack assembly comprising a plurality of base members each including a generally rectangular platform portion and an upstanding tubular portion at each corner of the platform portion having a plug dividing the interior thereof into upper and lower tubular volumes; a plurality of side support members each including a pair of spaced upstanding tubular portions and truss means interconnecting the tubular portions; and a plurality of core rod means sized to fit slidably within the tubular portions of the base members and of the side support members. In one embodiment, the core rods are elongated and unitary and have a length somewhat greater than the length of the side support member tubular portions so that the core rods may extend vertically within the side support member tubular portions and seat at their lower ends in the upper tubular volumes of the tubular portions of a lower base member and seat at their upper ends in the lower tubular volumes of the tubular portions of an upper base member. In another embodiment, each of the core rod means comprises a pair of core rod members each including an upper portion sized to fit slideably within the lower end of the tubular portion of an associated side support member or the lower tubular volume of a tubular portion of an upper base member; a lower rod portion sized to fit slideably within the upper end of the tubular portion of the associated side support member or the upper tubular volume of a tubular portion of a lower base member; and a collar portion intermediate the upper and lower rod portions to define the respective seated positions of the upper and lower rod portions.
