Abstract

Frame for bunk convertible seats, characterized, essentially because the frames constituting the bed bases are associated with each other by connecting rods located two to two on the frame beams, which connecting rods are the directors of the lifting or lowering movement of the sommier upper are articulated inferiorly to vertical stops mounted on the lower frame, on which stop the upper frame will rest when the assembly is folded, while above said cranks are able to move along rectilinear guides integral to the stringers of the upper frame the cranks are associated to the upper frame by means of intermediate connecting rods articulated respectively to each steering link and to a lower plate of the frame, which rods will act as reinforcement braces when the upper sommier is in its most stable position. Elevated has a linkage configured by an elbow plate articulated to the steering linkage and fitted by an extreme notch in a pivot of the connecting rod, all arranged in such a way that acting in opposite directions on the two steering rods of a side, provided for such effect of handles, will rotate inferiorly by its point of articulation while superiormente they will move by the guides making the rise or descent of the upper sommier whose movement will be helped by the action of a recuperator spring acting on a layered plate and articulated to the same axis of articulation as the steering rods.
