ABSTRACT:
A connector system joins together long rods or tubes at various angles to form a wide variety of shelter frames for diverse applications as well as railings, racks, and the like. The diverse connectors required are assembled from modules of the invention which are bolted together in various combinations. The modules fasten at one end to the rods or tubes. The other end of the module terminates in an annular gear adapted to intermesh at an adjustable angle with one or more gears of other modules. Once bolted together the modules form a rigid connector. The modules may be unbolted and reused to form a connector of another configuration. The few module types required to form the many connector configurations reduces inventory and manufacturing requirements.
