Abstract
A decorative, spherically shaped structure formed by a plurality of circumferentially spaced, elongated, pivotably interconnected ribs that lie in substantially coplanar, contiguous relation to each other when not expanded, but are readily expandable to form a discontinuous, substantially spherical body having top and bottom hub sections formed by end panels unitarily molded onto the ends of each rib. The pivotable interconnection between adjacent ribs is achieved by providing tabs on the end panels, the tabs having cylindrical apertures cooperatively alignable with mating tabs of adjacent ribs, permitting such cooperatively aligned tabs to be pinned or riveted together to form an integral structure. The end panels of each molded rib preferably further comprise cooperatively engageable lips having stepped cross-sections that intermesh to form substantially continuous upper and lower hub surfaces providing strength and rigidity to the expanded sphere.
