Abstract
A playyard system having an upper rail assembly with two parallel upper long side rails and two parallel upper short end rails. Each of the upper rails has a hinge with horizontal pivot pins adjacent to the midpoint thereof. The upper rail assembly also includes four upper corner brackets with hinges coupling the remote exterior ends of the four upper rails for rotation thereabout. In association with the upper rail assembly is a lower rail assembly with two parallel lower long side rails. Each of the lower rails has a hinge with vertical pivot pins adjacent to the midpoint thereof. The lower rail assembly also includes four lower corner brackets with pivot pins coupling the exterior remote ends of the lower rails to the lower corner brackets for oscillation of the lower rails about their axes and for pivoting with respect to the corner brackets. A pair of lower cross bars is included as part of the lower rail assembly. Each lower cross bar has exterior remote ends coupled to the lower rails at regions thereof intermediate the exterior remote ends and the midpoints of the lower rails for oscillating the lower rails about their axes and for rotating the cross rails with respect to t…
