ABSTRACT:
The invention relates to a rigid frame structure especially for a cabinet or like piece of furniture, e.g. of the shelved type comprising normally vertical uprights maintained laterally spaced from one another by normally horizontal lateral yokes, and longitudinally spaced by normally horizontal longitudinal cross-members, and characterized in that the yokes are provided with externally protruding tenons arranged substantially in the longitudinal plane of the yoke and substantially perpendicularly to the longitudinal edges of the yoke, which tenons are intended to be inserted or fitted, preferably with a tight fit, into corresponding sockets provided at the end of the vertical uprights.
This structure offers great simplicity of assembly.
