Claim:
A connection assembly for a frame structure, comprising: a first plate defining an inner face, an opposite outer face lying in a plane, and a bolt receiving bore extending between the inner face and the outer face thereof along a first axis at an acute angle to the outer face; and a tubular collar extending along a collar axis and being operatively connected to the first plate, the tubular collar being defined by a generally cylindrical wall extending circumferentially about the collar axis and having a first closed end and an open terminal end; a support rod extending along a rod axis and having an outer surface and a first end receivable in the open terminal end of the tubular collar such that the first end of the support rod is encircled by the cylindrical wall of the tubular collar, the rod axis being coincident with the collar axis with the support rod received in the open terminal end of the tubular collar; a first bolt extending through the bolt-receiving bore in the first plate; a first elongated frame member having a surface with a slot extending therein; and a first nut receivable in the slot in the first elongated frame member and including a bolt-receiving bore therein, the bolt-receiving bore adapted for receiving the first bolt in a mating relationship; wherein the outer surface of the support rod is continuous in a plane perpendicular to the rod axis.
