Abstract

1.somier for sofa-bed, of the type in which its stringers are articulated in four sections, leaving the headrest section suspended from vertical supports integral to a support frame, by means of a lever of second gender articulated by its center in the head and at the ends to the corresponding vertical support and a connecting rod whose free end is articulated to the corresponding side of the secondary intermediate section, so as to allow the extension movement, characterized in that said lever of second gender is folded in zeta and because in the area half of each head section is anchored a spring whose other spring whose other end is attached to the corresponding side of the support frame, equipped with small legs; at the points of articulation between the intermediate and tertiary intermediate sections of the stringers are articulated, a support leg for when the bed is extended, driven by means of a connecting rod linked articulately to a crowbar that articulates through the center in the central area of the corresponding lateral of the intermediate section, while the other end articulates in the support frame; near the lower end of said bell-shaped lever articulately receives a small rod that articulates its other end in a small appendix integral with a support articulated to the lower part of the support frame, whose support receives the corresponding end of a panel that will cover the front of the seat of the sofa, and when it extends to the bed position such panel tilts driven by the levers and previous cranks to a lower position, allowing the extension of the bed base. 2.somier for sofa bed, according to the preceding claim, characterized in that the tertiary sections on an upper end leg bent, so that when extending the bed base said leg is placed in the support position, while in the folding position is it adjoins the stringer, while the upper end bent supports a recess provided in the corresponding side of the secondary intermediate section, fixing the correct position of sofa; said actuating rod of the extreme leg receives articulated to another small connecting rod that in turn is articulated to a crosspiece conveniently articulated to the foot section; said crosspiece has a series of small springs that are fixed in transversal alignment to the elastic mesh of the bed base, facilitating its tensioning in the extended position, and in the folded position, in which position it forces the mesh to retain a dihedral folds without deformations. 3.
