Abstract

Abstract A disassemblable portable crib with a fabric crib body having a fabric floor and fabric sides and a frame suitable for supporting the fabric crib body. The frame comprises a frame base which forms a substantially planar platform held horizontally above the surface on which the crib rests and includes floor supports joined at one end to a central connector which extend beneath the floor of the crib body and feet joined at a second end of the floor supports. The frame also comprises upright corner posts joined to the frame base. The fabric crib body comprises fabric crib body sides joined with a fabric floor to form a box-like structure and means for snugly and slideably fitting the box-like crib body structure onto the corner posts such that the floor of the crib body rests on the floor supports and so that the crib body sides are tautly extended. Side stiffening members are joined to the body sides at their upper edges and extend along the entire width of the body sides. Floor stiffening members are joined to the crib body and extend across the crib floor from side to side. The resulting portable crib has significantly improved strength and rigidity over fabric bodied cribs in the prior art.
