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.

A multi-level rack assembly comprising: (A) upper and lower base members each including a polygonal platform portion and an upstanding tubular portion at each corner of the platform portion; (B) a plurality of side support members upstandingly and removably positioned between said upper and lower base members and each comprising a pair of vertically extending and laterally spaced tube means and truss means interconnecting the spaced tube means, each of said tube means having an inner diameter corresponding to an inner diameter of said base member tubular portion, extending between said upper and lower base members and axially aligned with respective tubular portions of said upper and lower base members, an upper end of at least one of said vertically extending tube means of said side support members abuttingly engaging a tubular portion of the upper platform member and a lower end of said at least one of said vertically extending tube means abuttingly engaging the corresponding tubular portion of the lower tubular member so that said at least one tube means transfers the loading imposed on said upper base member to said lower base member; (C) an elongated locating and aligning core rod respectively slidably received within each of said tube means, each of said core rods having a constant diameter throughout its length less than said inner diameter of said base member tubular portions and of said tube means and having a length exceeding the length of the respective tube means so that each rod projects out of the upper and lower ends of the respective tube means for slidable locating receipt of the projecting upper end in the corresponding tubular portion of the upper base member and for slidable locating receipt of the projecting lower end in the corresponding tubular portion of the lower base member; and (D) means preventing movement of said projecting lower ends of said core rods downwardly through said tubular portions of said lower base member whereby said rods locate said side members relative to said base members to facilitate assembly of the rack assembly, interconnect said base members and said side support members in the assembled condition of said rack assembly, and prevent relative lateral movement of said base members and said side support members by providing a continuous structural member extending through said tube means and into said upper and lower base members.
