Abstract
A frame connector assembly is configured to releasably, rigidly, and safely join large frame members to one another to form temporary structures. A connector assembly typically comprises a housing, a hoop element, a first cam block, a second cam clock and a rotatable actuator adapted to be engaged by a torquing tool. The housing is secured within the first frame member. Rotation of the actuator causes the threadedly-engaged second cam element to force movement of the first cam element in a direction opposing a spring bias. The hoop element is resultingly pulled toward the housing, along with a cleat or other detent element which is affixed to the second frame member. The housing can be manufactured inexpensively by way of extrusion. The frame connector assembly is adaptable to facilitate rapid construction and disassembly of various frame joint configurations, including end-to-face joints, and mitered 90-degree joints.
