Abstract
Abstract A foldable playpen having two end portions and two side portions which are interconnected to form a substantially square frame, and a flexible skirt forming a wall thereabout, where the two end portions are pivotable in a downward direction toward a center vertical leg located at each end, and the side portions are pivotable inwardly bringing the two folded end portions together, to thereby fold the playpen into a small, almost square area less than the area of the opened frame. The floor of the playpen is formed of spaced apart, hinged slats covered with a padding protection. The covered slats can be folded into a cylindrical shape which is adapted to receive the folded playpen frame therein, such that the entire playpen can be easily carried, such as by a handle connected thereto.

Claim 1
Independent Claim
451 words
A foldable playpen comprising: an upper frame including two end members and two side members; each end member including two end sections hingedly interconnected to each other at their respective inner ends to provide junctions; two pairs of legs, each pair having its upper ends hingedly interconnected with a respective one of said end members at said junction; two vertical legs, each having its upper end fixedly interconnected to a respective one of said end members at said junction; each side member including two side sections and first hinge means interconnecting said two side sections to each other at their inner ends for permitting said two side sections to be pivoted inward towards each other into a substantially parallel position with respect to each other, second hinge means interconnecting outer ends of said two side sections to outer ends of said end sections for permitting each of said two side sections to be pivoted to a substantially parallel position with respect to an associated connected one of said end sections; three bars, each bar including two bar sections and third hinge means interconnecting said two bar sections to each other at their inner ends for permitting said two end sections to be pivoted inward towards each other into a substantially parallel position with respect to each other, fourth hinge means interconnecting outer ends of two of said bars respectively between a corresponding leg on each of said pairs of legs adjacent bottom ends thereof for permitting each of said bar sections of said two bars to be pivoted to a substantially parallel position with respect to said corresponding leg connected thereto, fifth hinge means interconnecting outer ends of the third bar between said vertical legs adjacent bottom ends thereof for permitting each of said bar sections of said third bar to be pivoted to a substantially parallel position with respect to an associated connected one of said vertical legs; wherein, in an unfolded condition, each of said side members and said three bars are horizontal and substantially parallel to each other, each of said end members are horizontal and substantially perpendicular to said side members, and said pairs of legs diverge downwardly from their respective junctions; and in a folded condition, each of said end members are pivoted downward, said pairs of legs are placed inward toward their respective upright legs to provide folded ends, each of said side members are pivoted upward and inward, and said bars are pivoted upward and inward to bring said folded ends towards each other; whereby longitudinal axes of each of said end sections, side sections, bar sections and legs are disposed in the same direction in said folded condition to provide a compact arrangement.
Claim 2
Dependent Claim
451 words
A foldable playpen comprising: an upper frame including two end members and two side members; each end member including two end sections hingedly interconnected to each other at their respective inner ends to provide junctions; two pairs of legs, each pair having its upper ends hingedly interconnected with a respective one of said end members at said junction; two vertical legs, each having its upper end fixedly interconnected to a respective one of said end members at said junction; each side member including two side sections and first hinge means interconnecting said two side sections to each other at their inner ends for permitting said two side sections to be pivoted inward towards each other into a substantially parallel position with respect to each other, second hinge means interconnecting outer ends of said two side sections to outer ends of said end sections for permitting each of said two side sections to be pivoted to a substantially parallel position with respect to an associated connected one of said end sections; three bars, each bar including two bar sections and third hinge means interconnecting said two bar sections to each other at their inner ends for permitting said two end sections to be pivoted inward towards each other into a substantially parallel position with respect to each other, fourth hinge means interconnecting outer ends of two of said bars respectively between a corresponding leg on each of said pairs of legs adjacent bottom ends thereof for permitting each of said bar sections of said two bars to be pivoted to a substantially parallel position with respect to said corresponding leg connected thereto, fifth hinge means interconnecting outer ends of the third bar between said vertical legs adjacent bottom ends thereof for permitting each of said bar sections of said third bar to be pivoted to a substantially parallel position with respect to an associated connected one of said vertical legs; wherein, in an unfolded condition, each of said side members and said three bars are horizontal and substantially parallel to each other, each of said end members are horizontal and substantially perpendicular to said side members, and said pairs of legs diverge downwardly from their respective junctions; and in a folded condition, each of said end members are pivoted downward, said pairs of legs are placed inward toward their respective upright legs to provide folded ends, each of said side members are pivoted upward and inward, and said bars are pivoted upward and inward to bring said folded ends towards each other; whereby longitudinal axes of each of said end sections, side sections, bar sections and legs are disposed in the same direction in said folded condition to provide a compact arrangement.
Claim 3
Dependent Claim
