ABSTRACT:
A knock-down bookcase and shelf unit includes a pair of upright mirror image side members and a plurality of shelves which extend through relatively large openings in the side members, with the shelves being supported on the bottom edges of those openings so that the shelves lie in horizontal planes. Abutments are provided to prevent the shelves from shifting laterally relative to the side members. Also, an elongated, flexible resilient slat is positioned under each shelf with the opposite ends of the slat engaging in slits in the side members. Other abutments are provided to maintain the slats in a bowed condition so that the slats exert outward forces on the side members thereby stiffening the unit as a whole while supporting the shelves from below.
