Abstract
A collapsible playpen having a pair of spaced apart articulated end frames, wherein the end frames are separated by articulated upper and lower rails. The end frames and rails are constructed so that the playpen is collapsed by folding the lower rails to draw lower portions of the end frames together and simultaneously rotating the upper portion of the opposing end frames away from each other such that the distance between the upper portion of the end frames is greater than the distance between the lower portion of the end frames.
