A hinge positioned at the intermediate extents of the adjacent rail components to hold such components in an aligned orientation including a saddle with a central button aperture, interior plate apertures and exterior end apertures with associated rail pins for pivotally coupling the saddle and the adjacent interior ends of associated rail components, a pair of locking plates each with a plate pin coupling the upper end of each plate to a plate aperture of the saddle, each plate having an opening extending therethrough the plates urged away from each other, a liftable button with an elongated slot and with an associated button pin for slidably coupling the button to the saddle, the button having inclined bearing surfaces on their edges and an inwardly facing projection located at the adjacent interior edge of each adjacent rod segment, each projection having an upper curved surface and a lower planar surface receivable by the bearing opening.

[ What is claimed as being new and desired to be protected by Letters Patent of the United States is as follows:] [1.] In a playyard of the type having a frame with an upper rail assembly positionable in a horizontal orientation when in a deployed orientation and formed of two side rails and two end rails with each of the rails being formed of two rail components having interior ends and exterior ends, the interior ends being pivotally coupled with respect to each other for movement between the deployed orientation wherein the rails are horizontally disposed in a common plane and a collapsed orientation wherein the rails are vertically disposed and parallel, the frame also including a lower rail assembly positionable in a horizontal orientation beneath the upper rail assembly when in a deployed orientation, the frame also including four vertically extending corner rails pivotally coupling the upper rail assembly and the lower rail assembly, the playyard also having fabric components above the lower frame assembly and between the corner rails:a hinge positioned at the intermediate extents of the end rails and side rails to allow movement of the associated rail components between the horizontal orientation and each hinge including:a saddle in a generally inverted U-shaped configuration with a central button aperture, interior plate apertures and exterior end apertures with associated rail pins for pivotally coupling the saddle and the adjacent interior ends of associated rail components;a pair of normally vertically-oriented locking plates each with a plate pin coupling the upper end of each plate to a plate aperture of the saddle, each plate having an opening extending therethrough with a lower bearing surface and with springs urging the plates away from each other to a vertical orientation;a liftable button with a vertically-oriented elongated slot through a central extent thereof and with an associated button pin for slidably coupling the button to the saddle, the saddle having inclined bearing surfaces on their upper exterior edges; andan inwardly facing projection located on the interior end of each rail component, each projection having an upper surface and a lower planar surface with a notch whereby the notches are receivable with the bearing surfaces of the plates when the rail components are in axial alignment to thereby provide a supplemental force to maintain the playyard deployed and wherein upward movement of the button will allow movement of the inclined surfaces against the lower edges of the plates to urge the plates inwardly toward each other and thereby allow separation of the notches from the plates and subsequent movement of the playyard to the collapsed orientation.
