Abstract: A children's play structure includes a frame having hinging structures capable of being arranged into a free-standing structure and at least one interchangeable panel capable of removable attachment to the frame. The frame is easily assembled and is foldable into a compact structure when not in use. In another embodiment, a children's play structure comprises a unitary piece of relatively rigid, resilient plastic that has been scored in a generally vertical direction to create joints which form foldable frame sections. Interchangeable panels may be attached thereto by means of complementary pairs of hook and loop fasteners attached to the panels and to the frame sections. Alternatively, panels may be removably attached thereto by means of closed loop fasteners such as "O" rings. Such structures are stackable to form a multi-level play structure.

Abstract: A children's play structure includes a hinged frame structure having mounted thereon a plurality of panels depicting murals or scenes. The hinged frame structure which is comprised of a plurality of hinging sections and which is of lightweight, simple and economical construction is provided with substantial rigidity by corner structures which include hinging apparatus at the upper and lower ends of vertical tubes to permit pivoting rotation of the corner structure relative to one but not the other of a pair of frame sections coupled thereby. Each of the upper and lower hinging apparatus includes a clevis and a lever releasably coupled to the horizontal tubes of the adjacent frame sections by plugs with resilient release tabs. The clevis and lever have interleaved legs which receive a shaft and an opposite cap within apertures therein to permit pivoting rotation between the lever and the clevis while at the same time providing substantial resistance to unwanted vertical flexure.

Abstract: A children's play structure includes a frame having hinging sections capable of being arranged into a free-standing structure and interchangeable panels capable of removable attachment to the frame to provide multiple scenes on the plurality of hinging sections of the frame. The hinging sections of the frame comprise elongated beams or pipes joined at their opposite ends to form an open rectangular frame pivotally joined to adjacent hinging sections. In a first embodiment, the panels are provided by a piece of canvas folded over on itself and stitched together at opposite ends to form a sock which is dropped onto the frame. The canvas is easily replaced by another canvas having different scenes or murals to change the theme or environment of the play structure.
