  • the sides consist essentially of two uprights 1A, 13, forming respectively the front XII-XII of a detail of and rear leg of the same side.
  • the legs are joined to each other by an upper transverse-piece 1C and by a lower transverse piece 1D.
  • the two side structures of the divan are joined to' each other by longitudinal beams and bands (not illustrated for drawing convenience) to give the fixed structure of the divan.
  • the dropable or overtumable main framework that in the position of FIG. 1, receives upperly the seat cushions 3 (which can also be mobile) and has lowerly a mattres 4, anchored by known means, that forms the couch when thedivan is positioned to constitute a bed.
  • the back frame is generallyindicated.
  • Every side of the dropable framework 2 has a bridge 6 that joins two tubular structures 2A, 2B constituting the framework itself.
  • An arm 8 of a first crank-like lever is articulated to a pivot 7 of said bridge, and is hinged to the other end within a tube 9 connected with the front leg 1A.
  • Every side of the framework 2 has, towards the rearward part, a first bracket 10 projecting upperly and developing into a square (see FIG. 1 In the intermediate stretch, at the angle of said square, is fulcrumed an arm 11' of a second crank-like lever articulated to a tube 12 occurring at the lower transverse piece 1D.
  • Said arm at the tube l2 is connected with a lever arm 14 by means of a pivot 13.
  • a spring 15. is tensioned between a fixed point 16 and the end of said lever arm 14.
  • the arm 8, analogous to the arm 11, is connected through the articulation on the tube 9,-to a corresponding lever arm 17 to which anchors a second spring 18, anchored to the other end at 19.
  • the two arms 8, 11 are dimensioned in such a way so as to allow the drop structure 2 in the arrangement illustrated in FIG. 1 to assume a horizontal position.
  • the corner of said square can be reinforced by connections 23, they also developing as squares, and which are suitable to increase the surface of junction of the back itself.
  • a strut 24 is articulated at its two ends at 25 and 26 respectively between every square 21 and at the end of the horizontal extension 10A of the square 10. Said strut assuring the position of the back to be approximately vertical in the daytime arrangement, and controls the rotation of the back itself to arrange itself in a horizontal way, during the transformation from divan to bed.
  • the springs and 18 intervene, in the transformation from one to the other arrangement, to facilitate the beginning of the movement and to restrain it at the end.
  • FIGS. 6 to 12 illustrate an embodiment of a divan transformable into a double bed.
  • At 36 is indicated one of the two fixed sides, that are joined between them by longitudinal beams 37 and form together the principle skeleton resting through feet on the floor. ,A'transverse piece 38, aids to form the am.
  • a tiltableor drop framework made up of three sections articulated to each other, and formed from three frames 40A, 40C,'40D with spring members forming together the springed surface functioning as elastic-like nets. As is visible in the side view of FIGS. 6 and 7, the structure 40 can assume a rectangular position.
