Abstract
Abstract A collapsible construction set comprises a plurality of parts, each of which includes at least one integrally formed connector. A plurality of connector designs are provided. A first design includes a tapered receptacle and a stabilizing pin at the center of the receptacle. A second design includes a tapered end which fits in the receptacle and a hole which receives the stabilizing pin. A third design includes a ledge which forms a recess, and a fourth design includes a hook which engages the ledge and extends into the recess. The ledge of the third design is preferably formed adjacent the receptacle of the first design, and the second design preferably also includes at least one flange which overlies and holds a hook of the fourth design. To dismember the parts of a structure, a tapered end is moved out of the tapered receptacle until the stabilizing pin disengages from the hole, and then all of the parts of the structure topple.
