Definitions

  • the object of this invention is a hinge to move the backrest of a sofa forwards and backwards in a simple manner, achieving two different sofa depths.
  • This invention is characterised in that the hinge is specially designed and configured in such a way that an articulation mechanism is achieved that enables a sofa to be furnished with two different depths by moving the backrest forwards and backwards, but without the need to make a cut in the seat perpendicular to the backrest.
  • This invention is, therefore, confined within the field of armchairs and sofas, and in particular to those equipped with mechanisms for adjusting their constructive characteristics.
  • This type of mechanism is attached to the seat of the sofa and, by means of the relevant articulations, allows the backrest to be moved forwards or backwards. All the mechanisms on the market suffer from a serious disadvantage, which is the need for the seat to have a cut therein perpendicular to the backrest.
  • the object of this invention is to overcome the disadvantages of state of the art of mechanisms that allow the backrests of sofas to be moved forwards or backwards, in particular, the fact that a cut has to be made in the seat perpendicular to the backrest, by developing a hinge such as the one described below and the essential features of which are described in the first claim.
  • the object of this invention is a hinge that allows the backrest of an armchair to be moved forwards and backwards without the need to make a cut in the seat of the armchair perpendicular to the backrest.
  • the hinge to achieve the stated purposes comprises a first holding platform and a second holding platform arranged parallel to the first and placed one after the other, both platforms being connected to each other by a first angular element and a second connecting element, wherein both connecting elements have a right-angle shape and are connected in an articulated manner at their ends to the respective platforms, such that the first connecting element has a first vertical section that starts from the rear end of the first platform and is followed by a horizontal section that ends in an articulated manner at the rear end of the second holding platform, while the second connecting element comprises a first horizontal section connected in an articulated manner to the front end of the first platform and said first horizontal section is followed by a vertical section that is connected in an articulated manner to the front end of the second holding platform.
  • the second holding platform moves in such a way that it always remains parallel to the first holding platform, producing a forwards and backwards movement of the backrest attached to said hinge.
  • Figure 1 shows that the hinge that is the object of the invention comprises a first holding platform (1), or lower holding platform; a second holding platform (2) or upper holding platform both of which are arranged parallel to each other and connected by means of a first angular connecting element (3) and a second angular connecting element (4),wherein the first angular connecting element (3) has a first vertical section connected at its lower end to the first holding platform (3) by means of a first articular joint (3.1), the first vertical section being followed by a second horizontal section that is connected at its end to the rear part of the second holding platform (2) by means of a second articular joint (3.2), while the second connecting element (4) has a first horizontal section, which, at its end, is connected to the front part of the first holding platform (1) by means of an articular joint (4.1), said first horizontal section being followed by a vertical section, which, at its end, is connected to the front part of the second holding platform (2) in its front part by means of a fourth articular joint (4.2), so that the vertical sections of the first connecting element (3)
  • the first, second, third and fourth articular joint in a preferred but non-limiting embodiment, is formed by two parallel plates between which the end of the connecting element is housed and is traversed by a pin which acts as a pivot axis.
  • Figure 2 shows how the upper holding platform is moved from a backwards to a forwards position, keeping the second holding platform (2) horizontal at all times with respect to the floor.
  • Figure 3 shows how said hinge is arranged in such a way as to allow a backrest connected to the second holding platform to be moved to the forwards position.
  • Figures 4 to 6 show said hinge housed within the structure of the sofa and how, in order to be able to move the backrest of the sofa forwards or backwards, it is not necessary to have a cut in the seat that is perpendicular to the backrest of the sofa.
