The invention relates to the furniture industry, in particular for the production of furniture fittings and touches the mechanism of transformation of upholstered furniture.; The technical result of the claimed utility model "means transformation for upholstered furniture" is:; 1. A more rigid and robust design transformation means for upholstered furniture.; 2. Increasing insecurity transformation mechanism.; 3. Improved performance design transformation mechanism by comparison with a useful model adopted as a prototype ..; 4. The improvement of maintainability, since the transformation mechanism is collapsible.; 5. Reduction of wear carpet floor as rubber wheels are used.; 6. Reduction of sliding wear rubberized wheel and base frames, since they are fixed in the metal ferrule.; The technical result of the claimed utility model is achieved by the fact that, compared to a useful model adopted for the prototype "The means of transformation for upholstered furniture" comprising transformation mechanism comprising a sliding frame, with disposed in a front portion of the bearing rolling elements and mounted thereon additional soft element, hinged lever mechanism sidewall bonded to each other in the transverse direction of the plate-holders for mounting a soft member, wherein the transformation mechanism is provided with at least of three reference frames, comprising a base frame, said sliding frame and the fixed frame-based, wherein the base frame is mounted within the stationary frame base and is provided with a mentioned sidewalls, with longitudinal guides arranged in the lower portion of the base frame and are rigidly interconnected by cross members, the side rollers resting on the base frame guides, stops movement of rollers arranged on the rails in front of the base frame and the wheel supports, wherein the aforementioned sliding frame disposed within the base frame and comprises an arcuate drawer side disposed in a front portion thereof and fixedly connected to the rear transverse member by means of two longitudinal beams, on which is mounted said articulated-lever mechanism operable to lift the soft bed element and is provided with two lateral flanged rollers inserted in longitudinal guides of the base frame, and two stops located at the front of the drawer from the side-bar frame, in the inventive utility model, the transformation mechanism is made of a profile with a rectangular cross section of the four support members comprising mentioned base frame, a sliding frame, a fixed frame-based and is provided with a rotary frame, said base frame comprises longitudinal beams disposed in a lower portion of the base frame above said longitudinal guides, and contains an average longitudinal stiffening beam positioned in the center of the base frame and the additional center post which is fixed by welding yn -mentioned average longitudinal stiffening beams, with said two lateral roller flanged drawer frame fastened to the rear cross-member of the sliding frame, mounted on bolts cantilever-supported on longitudinal guides of the base frame and conjugate top with said longitudinal base frame beams and designed as movable bearings rolling retractable frame, allowing its movement in a horizontal position when transforming the sofa into the position of the "bed", and said hinged-lever mechanism This turns the bracket comprising two along the slot brackets adapted to change the length of the transformation mechanism by changing the gap between the rear transverse element of the sliding frame and the front cross member of the base frame, said side wall of the base frame are formed as rectangles, wherein said wheel base support frame mounted in the front part thereof and are formed as rubber-coated wheels, fixed in a metal cage, wherein said STILL zhny frame-basis is provided, arranged in front and rear of each side of the chassis base by two side walls, made of a profile with a rectangular cross section, fixed at the ends caps, wherein the sidewall of the fixed frame of the base are rigidly connected to each other by said longitudinal guide arranged below the sidewalls at the top of the chassis base, which are rigidly interconnected by a cross member, wherein said lateral base frame flanged rollers are fastened in the rear s portion of the rear strut of the base frame mounted to a support on said longitudinal guide frame-base conjugate top with said sidewalls of the carcass of the base and are designed as movable bearings rolling base frame to enable its movement up located on the upper front portion of the chassis base on said directing said restrictors are designed as stops in a horizontal position when transforming the sofa into the position of the "bed", and between the front and rear sidewalls mentioned Kark aca base formed openings removably through the openings of the side rollers with flanges, together with the base and retractable cages from the frame of the base, the frame-basis comprises lower longitudinal beams, connected by welding to the lower transverse elements mating struts to said side walls, wherein at the rear of the chassis base on top of the rear rack fixed brackets with arcuate slots, and said support frame are welded rotary cantilevered axis of rotation, which are mounted in arcuate slots in complements a bracket with the possibility of rotation with respect to the chassis member soft base on the rotation axis to form a backrest, wherein in the center, in the middle, on pivoting said support frame holds an additional stiffener.
