Abstract
A frame connector assembly is adapted to releasably secure first and second frame members in line with one another. The connector assembly includes first and second expansion elements elastically interconnected. The second expansion element includes two hollow lobes joined by a web. When the connector assembly is received by the two frame members, threaded rotation of one or more threaded actuators forces the expansion elements apart and into engagement with opposing primary walls of the frame members. The threaded actuator also presses against the web, thereby causing resilient outward rotation of the lobes. This rotation results in compressive engagement between the outboard edges of the second expansion element and respective intermediate walls of the frame members. Thus, the connector assembly imposes locking forces to the frame members along two axes orthogonal to the main axis of the frame connector assembly. The expansion elements may have an identical extrusion cross-section.
