ABSTRACT:
An apparatus for coupling tubular frame members is disclosed. A coupling block has a plurality of couplings extended therefrom. Each coupling has a guide recess, a clamp mounted for sliding movement within each guide recess, a bolt having a first end connected with the clamp and a second end screwed into the coupling. The clamp is provided with a hole which receives the first end of the bolt. A bearing within the hole supports the bolt at the first end for free turning movement. The bolt has a circular groove adjacent the first end, and a pin is mounted to the clamp and extended through said circular groove. The clamp is operable to slide responsive to the rotation of the bolt within the guide recess to press the tubular frame member surrounding said clamp and the coupling defining the respective guide recess thereby solidly holding said coupling and tubular frame member to each other.
