Horizontal shelf unit for handling papers

摘要

A shelf unit includes a U-shaped frame having a pair of spaced legs connected by a bight. The frame comprises first and second L-shaped members, having cooperable coupling structures provided at the ends thereof for rigidly and releasably interconnecting the members together. The cooperating coupling structures prevent movement of the L-shaped members relative to each other, except angular movement between a use position in which the legs of the frame are substantially parallel and an assembly position in which the outer ends of the legs are adjacent each other. The members can be separated in the assembly position to disengage the coupling structures. A plurality of vertically spaced horizontal grooves are provided on the inner surfaces of the frame, and a planar shelf can be slidably received in each groove when the L-shaped members are in the use position, thereby preventing the legs of the frame from moving toward each other. The coupling structures each include a flange and a recess on one L-shaped member respectively cooperable with a recess and flange on the other member.
