ABSTRACT:
A collapsible, portable child's play-pen, which may be foldably collapsed onto two half-members which are pivotably coupled together along an axis and which together form a base for the play-pen, which may then be subsequently folded together to form a compact portable unit. First and second frame members, each pivotably coupled to the base along parallel but mutually opposite edges of the base, form one set of opposite side walls of the play-pen. Each of the first and second frame members are provided with a respective pair of first and second pivotable linking arms. One end of each of the first pair of linking arms is pivotably coupled to a first frame member, and similarly one end of each linking arm of the second pair of linking arms is pivotably coupled to the second frame member. Each of the pairs of linking arms further possesses a releasible lock to allow releasible locking engagement of the other ends of the first pair of linking arms with the other ends of the second pair of linking arms so that when such linking arms are releasibly connected to each other they form generally parallel but opposite remaining sides of the play-pen when the play-pen is in the open position. The linking arms and frame members are adapted to support a flexible sheet in a vertical position generally around a periphery of the play-pen when the play-pen is in the open position to thereby form a plurality of vertical walls. A zipper is located on the flexible sheet along at least a portion of the upper side edges of the child's play-pen which when unzipped allows at least two of the linking arms to be pivoted free from the flexible sheet, and the unit folded in a collapsed position.
