Abstract
Embodiments may relate to a foldable play structure which may be easily assembled and which may be form of four or more panels each connected to another to provide an accordion fold structure; corner hinges comprising a first hinge portion attached to one panel of the at least four panels; a second hinge portion attached to another panel of the at least four panels; and a fastener configured to be retained within either the first portion or the second portion; and mid-wall hinge(s) attached to two of the panels and located between the corner hinges. Typically, in a first configuration, the panels of the accordion fold structure are folded to be stacked in substantially parallel planes, and in a second configuration, the panels are unfolded forming a play structure. The retained fastener may be used to secure the corner panels together.
