Abstract

A structural framework assembly made up of tubular members interconnected by a first connector arrangement which uses a connector having a concave surface pressing against a curved outer surface of a tubular member and having a pair of spreadable arms which are spread by a setscrew to lock inside an end of another tubular member, and a second connector arrangement which uses a connector plate extending into the end of a tubular member with the bottom of the connector plate inserted into a longitudinal slot at the bottom of the tubular member and a top tab on the connector plate inserted into an upper slot at the top of the tubular member. The longitudinal slot at the bottom of the tubular member opens out to the end of the tubular member and the upper slot is located at a distance from the end of the tubular member.
