Abstract

Divan of springs with simplified structure, of the type in which a set of springs stapled inferiorly to the support is fixed on a basic support grid and joined together by those of each row with those of the next one by means of a plurality of wires in a worm that cross transversely to the set of springs on its upper part, characterized by being established to form the metal structure a peculiar spring comprising a central stretch elongated and straight, endowed at each of its ends with a curvature that returns on the central section itself, formation that coincides with the plane of the upper and functional surface of the divan, the spring continuing, at both ends of said curves and symmetrically, by means of a single turn on each side in a helix or spiral downwards towards the plane of the frame, coinciding with which, each end is extended in a last section formed at right angles and whose angles dete they run a plane parallel to that of the support on which they rest to allow their stapling to the same, stapling that is verified through the innermost side of the two that form the mentioned angles, being perfectly aligned and facing the two short straight ends in the that completes the pier, having foreseen the possibility of replacing some of these springs in the whole frame, in internal areas of its surface and conveniently spaced, by simple wires, chords in format and structure with the upper plane of the springs claimed that, as staples, are intertwined floating thanks to the transverse worm, to determine a uniform upper surface of the metal frame.
