ABSTRACT:
A collapsible infant's crib is provided with hinged sides which fold inwardly. The side hinges are constructed to be slightly non-linear when in the open position, to provide an inward bias which prevents undue flexing of the joint when the crib is in use. The crib is held in open position by a tightly fitting bottom which opposes the inward bias of the sides and holds them straight. The sides are attached to the end of the crib by means of brackets of unequal length such that the crib folds down very compactly.
