Abstract: ahe support extends longitudinally beneath the worktop portion of the desk, structurally connects tubular legs, box legs, load-bearing drawer units and worktop portions and is formed by modular elements of predetermined length having at the ends thereof connecting elements for connecting modular elements end to end. Mountings are provided at intervals for laterally connecting other modular elements by means of connecting elements giving rise to various configurations. The modular elements and the connecting elements internally house power outlets and cables and are of channel section with large openings of intervals along their bottom and side walls, to permit easy access to the cables and to power outlets for supplying the items of electrical equipment which are supported by the worktop portions.

Abstract: A piece of metal furniture in sectional units comprises a base, two side panels, and a rear panel assembly. the assembly of these pieces is very simple and can be done by unskilled persons and without the use of any special tools or equipment. The base comprises complementary elements and locking devices which cooperate with corresponding parts of the side panels to allow the parts to be assembled and to be locked together, while taking up any relative play therebetween. The units are all of substantially parallelepipedal shape, resulting in less space being needed either for storing or for transport. The rear panel assembly is a modular assembly of individual rear panels wherein at least one dimension of the rear panel assembly is a multiple of the dimension of the base. Rear panels have the side edges which are suitably folded and shaped so as to interconnect with one another and with corresponding edges of the side panels.
