ABSTRACT:
A double tang articulating hub assembly used in combination with a collapsible self-supporting structure. The double tang articulating hub assembly is used as a connector among tubular rod elements which together provide a generally tubular frame matrix used to erect a collapsible self-supporting prefabricated deployable structure where a clear span interior without supporting columns is required. The hub employs a plurality of one piece “forked plugs” each containing a cylindrical plug with two tangs and an integral post connecting the tangs allowing the forked plug to rotate.
