Definitions

  • This invention relates to a sofa-bed according to the preamble part of claim 1 whose structure is such as to make easier to the user the opening and closing operations thereof, corresponding respectively to the transformation of the piece of furniture from a sofa to a bed, and vice versa.
  • sofa-bed Many types of sofa-bed are known wherein mechanisms are provided, embodying different arrangements, but being in any case devised with the objective of obtaining a variable or better modifiable position structure, so that it can be used in a first position as a sofa, for sitting on, and in a second position as a bed.
  • the particular connection arrangement between the various frames including the stationary one, which comprises the sofa base structure, allows opening of the sofa, and consequently closing thereof, to be performed through a single operation.
  • the sofa according to the invention is comprised of a stationary frame generally shown at 10, and of two movable frames, shown at 11 and 12 respectively, wherein first movable frame 11 is adjacent to the stationary frame 10, while second movable frame 12 comprises the sofa end frame in the bed position thereof.
  • Both stationary frame 10 and the two movable frames 11 and 12 are made up of metal tubing and have a substantially rectangular shape wherein the longer sides comprise the transverse beams of the sofa, while the shorter sides, aligned with each other, comprise the side edges of the piece of furniture.
  • a back 13 is connected in any known way and can be of any desired shape.
  • Stationary frame 10 is provided, at the four corners thereof, with support legs 14, while movable frames 11 and 12 are provided, only at the front corners thereof, with support legs shown at 15 and 16 respectively.
  • support legs 14, 15 and 16 are all the same height, for obvious reasons of arranging the sofa in the bed position ( Figure 4).
  • Figure 2 In the sofa position ( Figure 2), support legs 15 and 16 of movable frames 11 and 12 will remain slightly raised from the ground but that will not impair the stability of the piece of furniture in said position.
  • substantially resilient members which, in the embodiment shown herein, are comprised of wooden strips also known as "slats", whose ends are inserted through the longer sides of frames 10, 11 and 12, whereby they extend longitudinally, i.e. in a direction parallel to that of sofa opening and closing.
  • Wooden strips or slats 17 replace the conventional bed wire net, which could be used in any case for the subject sofa as well without any modification to the innovative concept.
  • the three frames 10, 11 and 12 are connected to each other by means of an assembly of three substantially straight rods, whereby movable frames 11 and 12 can go from the Figure 2 position (sofa) to the Figure 4 position (bed) through an intermediate position, shown in Figure 3, by means of a traverse movement along a substantially semicircular path.
  • First movable frame 11 is connected, at the ends thereof, both to second movable frame 12 and to stationary frame 10. More particularly, first movable frame 11 is connected to the second movable frame by means of a substantially straight rod 18 pivoted at 19 on the front end of first movable frame 11, and pivoted at the opposite end, at 20, on second movable frame 12 in a region thereof slightly set back relative to the centerline position.
  • First movable frame 11 is also connected to stationary frame 10 by means of a substantially straight rod 21 pivoted at one end thereof on the rear end of movable frame 11 and, at the opposite end, at 23, on stationary frame 10 at a region substantially set forward relative to the centerline position thereof.
  • the three frames 10, 11 and 12 are connected to each other by means of a substantially straight rod 24 of a larger length compared to the above rods 18 and 21, being in particular of a length which is substantially equal to the sum of the lengths of the rods mentioned above.
  • Connecting rod 24 has one end pivotally connected, at 25, on the front end of stationary frame 10 and the other end pivotally connected, at 26, on the rear end of second movable frame 12, while in a substantially intermediate position said rod pivots, at 27, on first movable frame 11.
  • opening and closing of the sofa i.e. the transition from the Figure 2 position to the Figure 4 position takes place through a single operation in that the three frames 10, 11 and 12 are completely connected to each other.
  • said motion causes a corresponding motion of first movable frame 11 connected thereto by means of rods 24 and 18, and the two frames perform the motion mentioned above relative to stationary frame 10 simultaneously, in that they are connected to stationary frame 10 through rods 24 and 21.
