Abstract
Abstract There is disclosed a crib which can be folded into a highly compact form, and which can be converted for use as a playpen or a dressing table with a minimum of effort. The unit includes four legs each of which is pivoted at its upper end to a side of a foldable rim, and each of which has a link which connects another point on the same side of the rim to an intermediate point on the leg. Between those pivot points on the leg connected between the rim and the link there is provided a hinge joint which permits the two sections of each leg to be rotated 180* relative to each other. At a point further below the link pivot on each leg, there is provided another link which connects the leg to the side of a floorboard section. The four lower links permit the floorboard to be switched between two distinct positions with a minimum of effort.
