Abstract
A stackable set of tray carrying units is disclosed wherein each unit has a floor member and a ceiling member. Each of the floor and ceiling members has downwardly extending feet, and the ceiling member also has upwardly extending split posts. The floor and ceiling members are connected together by vertical beams having upper and lower I-beam extensions which frictionally engage with the respective feet of the ceiling and floor members. The stacking arrangement is such that each of the split posts of the ceiling member is sized to frictionally fit within one of the feet of a floor member assembled on top of the ceiling member, with the web of the lower I-beam extension of a beam in an upper one of such units having an interference fit with the space defined by the split post of a lower one of such units.
