Portable playpen

Claim 1

A portable, foldable playpen (10) comprising upper (12) and lower (14) frames, each having a plurality of side (16) and end (18) members pivotally interconnected (34) with each other side (16) and end (18) members of said upper (12) frame positioned vertically above corresponding side (16) and end (18) members of said lower (14) frame, a flexible enclosure (42) attached to members of said frames, and vertical members (32) having pivotally interconnecting means with the pivotal interconnections (34) of the side (16) and end (18) members of said upper (12) and lower (14) frames, the inner ends of sections (38, 40) of the vertical members (32) and the inner ends of sections (20, 22) of the end members (18) in each of said upper (12) and lower (14) frames having pivotally interconnecting means (24, 50) for permitting, in cooperation with the upper (12) and lower (14) frames and the pivotal interconnections (34) of the vertical members (32), said upper (12) and lower (14) frame end (18) members and said vertical members (32) to be collapsed into substantially parallel and abutting arrangements relative to each other and relative to side (16) members, the pivotally interconnected means (24) of the vertical members with the pivotal interconnections (34, 50) of the side (16), end (18) members and vertical members (32) comprising locking and interlocking means for preventing the collapsing of the upper (12) and lower (14) frame end (18) members, until the pivotal interconnections (24) are collapsed, wherein when in an unfolded condition said upper (12) and lower (14) frames lying in substantially parallel planes with side (16) and end (18) members of the upper (12) frame aligned vertically with the respective side (16) and end (18) members of the lower (14) frame and the side (16) and end (18) members of the upper (12) and lower (14) frames being positioned orthogonally to the vertical members (32) to form an enclosed play area with said flexible enclosure (42), and when in a folded condition the pivotal interconnections (34) of the upper (12) and lower (14) frames side (16) and end (18) members with the vertical members (32), in cooperation with the pivotally interconnected inner ends of sections (20, 22) of the end (18) members in each of the upper (12) and lower (14) frames permit each of said upper (12) and lower (14) frame end (18) members to be collapsed into substantially parallel and abutting arrangements relative to each other and relative to side (16) members, and the pivotal interconnections (34) of the upper (12) and lower (14) frame side (16) and end (18) members with vertical members (32), in cooperation with the pivotally interconnected inner ends of sections (38, 40) of the vertical members (32) permit the side (16) members of each of the upper (12) and lower (14) frames not having any pivoting interconnections to be positioned substantially parallel to and in abutting arrangements relative to each other and relative to end (18) members and vertical members (32) to form a compact arrangement with said flexible enclosures (42).
