Long span canopy frame connectors

摘要

A frame for supporting a fabric canopy or tent is formed from a number of elongate rigid cylindrical elements, tubes or rods, joined by a variety of special connectors. They form a frame of interconnected rigid trusses. Each truss has an upper chord and a spaced-apart lower chord connected by rigid members therebetween to form trusses with sufficient rigidity to span greater unsupported spans than conventional canopy frames. Each connector has a plurality of tubular receptacles for receiving the cylindrical elements and transverse threaded apertures for threaded locking fasteners for securing the cylindrical elements in place.
