A lifting device for articulated folding structures of sofa-beds comprises a fixed support framework (2) and a pantograph leverage (4) operatively active between a first main movable frame (3) of an articulated folding structure of a sofa-bed and the fixed support framework (2), to move the first main movable frame (3) in a vertical direction between a first position at which it is housed at the bottom of the fixed support framework (2) and a second position at which it is raised relative to the framework itself (2). The lifting device further comprises first and second means (8, 10) for connecting the pantograph leverage (4) with the first main movable frame (3), which means consists of at least one oscillating link (9, 11). <IMAGE> |
