Abstract

A foldable playpen formed by rigid panels, each panel comprising two horizontal bars connected by vertical bars. Adjacent panels are joined to each other by flexible deformable elements which are attached to the ends of the horizontal bars. The panels are each locked in position to form a rigid structure by means of cross members which are inserted between vertical bars of adjacent panels so as to span the angle formed between the adjacent panels.
