The transformation tool for upholstered furniture, contains a transformation mechanism made of three supporting elements, including the base frame 1 (Fig.Z), a retractable element 2 (Fig.Z) and the headrest frame 3 (Fig.Z). The base frame 1 (Fig. 3) is installed inside the stationary frame of the sofa 4 (Fig. 1,4,5) and is equipped with sidewalls 5 (Fig. 1,2,4,5), made in the form of arcs, in the upper part of which are fixed plates 6 (FIG. 3) for mounting the seat of the sofa 7 (FIG. 1, 2, 4, 5), longitudinal guides 8 (FIG. 1, 2, 4, 5), rigidly interconnected by transverse elements 9 (FIG. 3) made of pipes, wheel supports 10 (Fig. 1,2,4,5), two brackets And (Fig. 1,2,4,5) located in the rear part from the side of the headrest frame 3 (Fig. C) with side rollers 12 (Fig. 1,2,4,5), based on the guide lining 13 (Figs. 1,2,4,5) of the sofa frame 4 (Figs. 1,4,5) and limiters 14 (Figs. 1,2,4,5) to move the rollers 12 (Figs. 1,2,4 , 5), made in the form of holes located on the guides 13 (Fig. 1,2,4,5) in front of the frame of the sofa 4 (Fig. 1,4,5). The head frame 3 (Fig. 3) is fixed with its frame 15 (Fig. 1,2,4,5) with a one-piece swivel on two brackets 16 (Fig. 1,2,4,5) mounted in the back of the arches of the sidewalls 5 ( Fig. 1,2,4,5) of the base frame 1 (Fig. 3), and in its rear part two brackets 17 (Fig. 1,2,4,5) with side rollers 18 (Fig. 1,2, 4,5), based on the guides 19 (Fig. 1,2,4,5) of the sofa frame 4 (Fig. 1,4,5), while four plates 20 are mounted in the corners of the frame of the headrest frame 3 (Fig. 3) (FIG. 3) for attaching the soft element 21 (FIG. 1, 2, 4, 5), wherein said retractable element 2 (FIG. 3) positioned inside the base frame 1 (Fig. 3) and contains an arcuate collet 22 (Fig. 1, 2, 4, 5) located in its front part and rigidly connected to the rear transverse element 23 (Fig. 3) using two longitudinal beams 24 (Fig. 2), on which the articulated lever mechanism 25 (Figs. 1,2,4,5) is mounted, made with the possibility of lifting the soft element 26 (Figs. 1,2,4,5) and provided with two side rollers with flange 27 (FIG. 1,2,4,5) inserted into the longitudinal guides 8 (Fig. 1,2,4,5) of the base frame 1 (Fig. 3) and two stops 28 (Fig. 1,2,4,5) located in front of the side of the arcuate collet 22 (Fig. 1,2,4,5) of the retractable element 2 (Fig.Z). Retractable element 2 (Fig.Z) has wheel bearings 29

(figure 2). Under the guides 13 (Figs. 1,2,4,5) of the sofa frame 4 (Figs. 1, 4, 5), the legs 30 (Figs. 1,2,4,5) are mounted. The transformation mechanism is made of metal tubular frames 1, 2 and 3 (Fig.Z). The guides 8,13,19 (Fig. 1,2,4,5) are made of metal, and the side rollers 12 (Fig. 1,2,4,5), the side rollers 8 (Fig. 1,2,4,5 ) and rollers with a flange 27 (Fig. 1,2,4,5) are made of plastic.

The work of the transformation means is as follows.

When the transformation mechanism is unfolded into the “bed” position (FIG. 2), a pull-out element 2 is pulled out behind the collet 22, the wheel bearings 29 that come out of the footboards 30 move along the floor, while the rollers with the flange 27 move along the longitudinal guides 8 of the base frame 1. After the rollers with the flange 27 abut against the sidewalls 5, the movement of the base frame 1 begins, which moves on the wheel supports 10 along the floor, on the side rollers 12 along the guides 13 of the sofa frame 4 to the limiter 14, made in the form of holes, where the transformation mechanism fix camping in the unfolded position. Simultaneously with the movement of the base frame 1, the movement begins and the headrest frame 3, which moves on the side rollers 18 along the guides 19, rotates relative to the bracket 16 and occupies a horizontal position. Then, from the sliding element 2 behind the frame of the soft element 26, moving up on itself, and then down from itself using the articulated lever mechanism 25, the soft element of the berth 26 rises, gets into place with the seat of the sofa 7, rests on the drawer 22 and thereby fixes the base frame 1 and the sliding element 2 relative to each other.

When unfolding the means of transformation in the position "sofa with increased depth of seat, they perform the same actions as when unfolding the means of transformation in the position" bed. The only difference is that after the transformation mechanism is completely unfolded into the “bed” position, the sliding element 2 behind the collet 22 is moved inside the base frame 1, while the side rollers 12 of the base frame 1 remain fixed in the limiter holes 14 of the guides 13, the headrest frame 3 remains in a horizontal position, resting on the guides 19 on the side rollers 18.

The proposed transformation tool compares favorably with prototin in that it greatly simplifies the process of unfolding it, since it is only necessary to push all the frames to the stop and raise the soft element 26. Moreover, all the soft elements 7, 21, 26 of the sofa automatically occupy a horizontal position and are securely fixed.
