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 frame having hinge structures that enable the structure to be arranged into a free-standing structure having a variety of adjustable positions. Interchangeable panels can be provided for removable attachment to the structure. At least one of the panels may include an article mounting sheet configured to receive articles such as drawings, photographs, and the like in one or more transparent pockets. The frame is easily assembled and is foldable into a compact structure when not in use. A hinge mount structure having two mounting posts facilitates assembly, disassembly, folding, and adjustable positioning, and affords structural stability to the free-standing play structure. In particular, such a hinge structure allows adjoining frames to be mounted at the same level and to be freely pivoted independently of one another. Further, a coupling structure enables portions of the play structure to be divided into segments that can be attached upon assembly.

Abstract: A container is presented having a hollow substrate with a coating covering at least a portion of the substrate. The coating includes a mixture of a base material and an adhesive where the base material is absorbent with respect to nontoxic dyes such as food coloring. One preferred base material includes rice powder. The substrate can be egg shaped, so that the coated container forms a synthetic Easter egg that can be colored with food coloring.

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.
