ABSTRACT:
A slidably staggerable tiered document tray has upper and lower trays with feet. A pair of risers slidably mounted on the side walls of the lower tray provides vertical separation between the upper and lower trays. The risers are designed with ledges upon which the upper tray rests and the feet on the upper tray extend through holes in these ledges and thereby couple the upper tray to the risers. The risers are held on the lower tray with interlaced inner bottom tabs and outer bottom tabs having an alternating inner bottom tab and outer bottom tab arrangement along the length of the risers that slidably attach over the side walls of the lower tray. The upper tray is held on the riser ledges by a combination of the operation of the upper tray feet loosely coupling with the holes in the ledges and tabs on the risers that are in contact with the outside of the upper tray side walls.
