Knock-down furniture assembly
First Claim
1. In an article of furniture having selected components which are adapted to be disassembled and reassembled in a given direction, a joint providing for such disassembly and reassembly between said selected components comprising two axially mutually separable slip fitting elements, one said elements being affixed to one of said selected components and another said element being affixed to another of said selected components, said elements being arranged with their axial slip fit in the same direction as said selected components are adapted to be disassembled, and means for releasably locking said elements when they are mutually slip fitted, said locking means comprising set screw means threadably engaged with a transverse threaded bore of said one element and selectively operable transversely of the direction of slip fit to one position for transversely directly contacting and forcefully bearing against said another element and forcing said another element against said one element thereby to lock said elements against axial separation and to another position permitting said elements to axially separate, one of said selected components having a bore aligned with and forming a continuation of said transverse threaded bore of said one element, said set screw means extending into the end of said continuation bore adjacent said one element and being non-protruding from the opposite end of said continuation bore of said one selected component when said set screw transversely forcefully contacts said another element.

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.

- 2. In an article of furniture having selected components that are disassemblable and reassemblable in a given direction, a joint providing such disassembly and reassembly between respective confronting surfaces of said selected components, said joint comprising two axially mutually separable slip fitting elements, a first said element being affixed to one of said selected components and comprising a hollow tubular sidewall extending from one of said components and perpendicularly to the confronting surface thereof, a second said element being affixed to another of said selected components and comprising a shank, said elements being arranged with said first and second elements axially longitudinally aligned and with the direction of their axial slip fit being the same as the given direction of assembly of said selected components, and means for releasably locking said elements when they are mutually slip fitted comprising means engaged with one of said elements and selectively operable transversely of the direction of slip fit to one position for directly contacting and forcefully bearing against the other said element and forcing said other element against said one element thereby to lock said elements against axial separation and to another position permitting said elements to axially separate.

11. A joint for attaching a first component of an article of furniture to a second component thereof, comprising:
-
an elongated tubular member, mounted at one end to said first component, said tubular member having an end opening, a sidewall, and an access opening in said sidewall; an elongated bar member, mounted at one end to said second component and being adapted to axially slip fit into said tubular member through said end opening, said bar member including a transverse threaded bore; and means for locking said bar member within said tubular member when said bar member and said tubular member are operatively assembled, said locking means comprising a set screw threadedly engaged with said transverse threaded bore, said access opening being located to align with said threaded bore and provide access to said set screw when said bar member is slip fit into said tubular member, said set screw being selectively operable to directly contact and bear against said sidewall of said tubular member. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
