ABSTRACT:
A knock-down furniture assembly comprises a joint construction between furniture components wherein a rod has a slip fit engagement with a bushing. The rod is affixed to one component and the bushing to another. In one embodiment, the rod has a head which fits within a hole in a first wood component and is captured by means of cured epoxy resin introduced into the hole around an immediately adjacent portion of the rod's shank. The remainder of the rod projects from the first wood component and when the first wood component is moved into assembly with a second wood component, the rod slip fits within the bushing on the second wood component. Set screws are threaded into tapped holes in the sidewall of the bushing and are accessible through aligned holes in the second wood component for actuation by a polygonally shaped wrench engaging similarly shaped sockets in the ends of the set screws for tightening against the inserted rod shank thereby to lock the two components in assembly, and for loosening to unlock them. The disclosed embodiment is in an upholstered chair.
