摘要

Improvements in the articulated systems of convertible furniture, characterized by comprising a constructive arrangement integrated by the combination and coordination of all its components, assembled with the metal frame of the furniture itself, constituting an articulated, extendable and retractable monoblock whole, whose components are organized laterally on both sides of the furniture, based on a plurality of levers-parts that make up a device whose elements consist of a bar top, linked at the top, with the possibility of rotation, to a second bar that is fixed at the bottom to the first articulated section of the frame. And that in the initial position corresponds to the back of the sofa, while the lower part of the first bar is fixed to a second frame positioned in the lower plane, in conjunction with an opposing spring that completes this first mobile constructive arrangement, which is combined with a third revolving bar whose end free is joined with another bar with figure of circular sector, which in turn, at the other end is joined, with rotating juago, with the second frame of the combined frame and with another curved bar, which is attached to the frame located on the bottom lower, in conjunction with an elastic recovery device that contributes to the articulated and sliding play of the system, which still has another bar that joins the third articulated section, while inferiorly it is free of all ties, so that in the total deployment it fits in a throat that, for this purpose, has practiced said section, thanks to a pivot provided for this purpose, at the same time, said third section has a bar that is attached to it with the small section or supplement that completes the final conformation of the piece of furniture, in conjunction with a profile that in the folding down of the frame assembly, performs the function of the rear support leg of the bed in collaboration with another intermediate leg fixed to a bar with figure d e four that is set with the aforementioned curved bar, with free rotating play, artifice that provides greater stability to the piece of furniture that also has ratchet pieces that fix the immovability of the articulated parts of the support frame in its deployment and conversion into bed furniture .
