ABSTRACT:
A folding joint for a foldable playyard having a base frame having two connecting members pivotably secured at the inside for holding two rails permitting them to be held in a longitudinally aligned position or folded up into a collapsed position. The connecting members each have an axial hole at one end for inserting either rail, two through holes on two opposite side walls thereof, and a track connected between the two through holes. The rails each have a pivot hole secured between the two through holes by a headed pin. The two rails are held in the longitudinally aligned position when the head of the headed pin is engaged in one through hole; and the two rails are allowed to be folded up when the head of the headed pin is rotated to the other through hole.
