Joint construction such as for furniture and method of making

Claim 1

In a furniture joint construction; at least two rigid wood-like rail members substantially rectangular in cross section and having parallel outer and inner side surfaces and having top and bottom edges disposed in respective parallel planes, said rail members having a greater dimension between said edges than between said side surfaces, said members being disposed with the said inner side surfaces at an angle of less than 180° to one another, each member having one end part in juxtaposed relation to one end part of the other member, and a block of plastic material which undergoes an irreversible reaction upon curing molded and cured in situ on the juxtaposed said one end parts of said rail members and rigidly bonded thereto, said block of plastic material being rigid when cured and engaging at least the outer and inner side surfaces and bottom edges of said members and bonded to said outer and inner side surfaces and bottom edges, said block having outer faces spaced outwardly from the outer side surfaces of said rail members and having inner face means extending between the inner side surfaces of said rail members, said block having a top face substantially in the plane of the top edges of said members and having a bottom face disposed below said bottom edges of said rail members, said block having a socket formed therein through the bottom face and extending upwardly into said block between the said one end parts of said members, said socket adapted to receive the upper end of a leg member, said block being of ample dimensions to transmit substantial loads between said rail members, a panel in a plane between the planes of said top and bottom edges of said rail members, said rail members being grooved on the inner sides to receive the adjacent edges of said panel, and the region of said panel near the said juxtaposed one ends of said members extending into said block and being bonded thereto.
