Abstract

A collapsible three dimensional support structure is provided which may be either free standing or adapted to hang from an overhead support. The structure has utility as an ornament or ornament support as well as general utility as a support rack. The structure includes a base formed from interfitting flat cross members which includes an upstanding central post member and a collapsible and expandable cover structure which mounts on the base. The cover structure is made of a single element comprising concentric rings connected by integral flexible connectors which permit the rings to be laterally separated along an axis normal to their common center point to form a conical framework. The cover element is placed over the upright post member and expanded along its longitudinal axis and connected to the top and bottom portions thereof to form a conical configuration. Interfitting flat decorative top pieces may be press fitted to the top end of the central post. A hanger element may also be provided which adapts the structure for hanging from an overhead surface.
