  • Patent number: 4225181
    Abstract: A rugged and stylish wooden chair shippable in compact knock-down form includes separate prefabricated back and arm subassemblies with lower portions proportioned to serve as contour-blended marginal parts of the seat of a seat-leg assembly, the cooperating sub-assemblies being readily united and fastened together securely and unobtrusively with the aid of laterally-extending dowels and bolts. Major stresses occurring at joining sites are advantageously in shear and are reliably resisted by both the dowels and the bolts, and corner posts for the back are prefabricated as parts of the arm sub-assemblies to realize outstanding structural strength. Rocker runners may be fastened to the lower ends of the seat legs, in a rocking-chair embodiment, and each runner thereof is provided with one leg-socket and fastener opening of elongated form accommodating the somewhat coarse leg-spread tolerances expected for the seat subassemblies.
