An improved play yard having a lower horizontal support formed of rails, an upper horizontal support formed of rails and vertical support rails pivotably coupled therebetween, a central hub pivotably coupling the radially interior ends of the rails of the lower horizontal support and hinges coupling the rails of the upper horizontal support at intermediate locations. The hinges are adapted to be rotated about their axes between a locked position wherein the play yard is secure for operation and use and an unlocked position wherein the upper rails may be pivoted and the entire play yard collapsed upon the raising of the hub. Also disclosed is the hinge per se.
