Mattresses And Other Support Structures For Chairs And Beds
(AREA)
Abstract
Folding structure for sofa-bed, of the type consisting of a support base and a folding frame formed by pairs of elements of rectilinear rods, articulated to each other, and by a normal bed mesh, characterized in that each structure is endowed with a series of articulated rods, arranged symmetrically on each side, of the frame which serve to allow the folding of the rectilinear elements of the frame, in such a way that they are alternately arranged parallel and perpendicular to the support base, and to allow the folding of the legs, so that the latter are arranged parallel and perpendicular respectively to the elements of the frame; because it presents a first articulated joint for the folding of the anterior legs of the bed; a second articulated joint for folding the intermediate legs of the bed; an adjustable plane to contain the mattress and the support of the cushions, joined to the frame by means of a first articulated rod train; a second train of articulated rods for the folding composed by sofa-bed.
