Abstract
Abstract A foldable crib for a child having hinged wall sections and hinged corner sections adapted to accordian-fold into a compact unit with a backwall section embracing the other wall sections and into a package having the general shape of an ordinary suitcase. A handle at one edge of this folded unit permits it to be easily carried. A cloth-type floor in the crib, with the weave arranged on a bias, stabilizes the same when opened, and when folded, the floor section is merely pulled upwardly between the wall sections. The auxiliary features may be incorporated in this crib, on the opposing sides of the backwall section, such as a mattress and a foldable baby seat, the same enhancing its usefulness and versatility.
