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.
A knock-down chair comprising a first prefabricated sub-assembly including a central seat part having four depending legs fixed therewith, said central seat part lacking side and rear marginal portions needed to complete the full side and rear lateral expanse of the seat for the chair, second and third prefabricated sub-assemblies each including arm rest means respectively fixed with and extending above right and left marginal seat parts which are proportioned to abut with the right and left sides of said central seat part and to complete the right and left side lateral expanse of the seat, a fourth prefabricated sub-assembly including back rest means fixed with and extending above a rear marginal seat part proportioned to abut with the rear of said central seat part and to complete the rear lateral expanse of the seat, and means for securing said marginal seat parts in abutted relationship with said marginal portions of said central seat part.
A knock-down chair comprising a first sub-assembly including a central seat part having four depending legs fixed therewith, said central seat part lacking side and rear marginal portions needed to complete the full side and rear lateral expanse of an exposed uncovered seat for the chair, second and third sub-assemblies each including an upstanding support fixed with and extending above right and left marginal seat parts proportioned to abut with the right and left sides of said central seat part and to complete the right and left side lateral expanse of the seat, a fourth prefabricated sub-assembly including back rest means fixed with and extending above a rear marginal seat part proportioned to abut with the rear of said central seat part and to complete the rear lateral expanse of the seat, laterally-extending means for securing said marginal seat parts in abutted relationship with said marginal portions of said central seat part and strongly resisting separations therebetween in shear, and means for securing said back rest means with said upstanding supports of said second and third sub-assemblies.
A knock-down rocking chair comprising a sub-assembly including a seat part having four depending legs fixed therewith, the lower ends of said legs being formed as tenons of cross-section reduced in relation to wider leg portions immediately thereabove, and further comprising a pair of elongated rocker runners each having a pair of uniformly-spaced mortise-type openings recessed into the top thereof, said openings being spaced about the same as the spacing between a front-and-rear pair of said legs along a side of said seat part, one of said pair of openings fitting closely about one of said tenons of one of said pair of legs and the other being of elongated configuration and elongated in the direction of elongation of said runner, said elongated recess being of length not greater than about the combined lengths in the same direction of half the cooperating tenon and half the leg portion immediately thereabove, whereby a runner may be affixed to a pair of said legs by fitting one of said tenons snugly into the close-fitting opening thereof and inserting the other tenon into the elongated opening, the latter being thereby closed by the wider leg portion above the said other tenon, and bolt means for fastening said runners with lower ends of said legs through restricted openings communicating with said mortise-type openings from below.
