Abstract

Sofa with folding frame for bed, which being of the type that have a frame divided transversely into three sections articulated with each other, essentially characterized in that the end section (1) is articulated to two pieces (2), which in turn they articulate with the bends (3) elbowed and these with the legs (4) of the section (1), in such a way that when folding the section (1) on the central theme (5), the tilting of the legs is achieved (13). ); the parts (2) being articulated to the central section which has plates 6 with articulation therein; and on the plates (3), also having folding legs (7) with braces 8 and arms (9) in whose articulation with the section (5) there are other arms (10) that articulate to the free ends of tilt plates (11) that are joined at their midpoints, by means of tie rods (12), to other tilting plates (13), smaller than the previous ones and parallel to them. With the particularity that both tilting plates (11) and (13) are jointed together, by a composite strut. By two plates (14) and (15) articulated with each other, the plates (14) joining the free ends of the tilting plates (13) with the end of the central section (5), and the plates (15) that join said plates (14) with the free ends of the tilting plates (11); further characterized the strips (15) joins the inner section (16) by means of braces (17) with a slotted collet to adjust the inclination between the central section (5) and the internal section (16).
