  • the present disclosure relates to a sofa-bed or armchair-bed comprising an articulated mechanism 1.
  • an articulated mechanism according to the present disclosure is denoted with reference number 1.
  • the articulated mechanism comprises a profiled element 10 having an end region, or terminal, 10a at which there is profiled element in the shape of a "C", that is, a "U”, or in the shape of an "H".
  • the profiled element 10 in the end region 10a has a cross section in the shape of a "C", "U”, or "H”.
  • the profiled element 10 includes, at this end region 10a, a first wall 101 and a second wall 102, opposite each other, that is, facing each other, to form the two flaps of the profiled element in the shape of a "C", "U” or "H".
  • the articulated mechanism 1 further comprises an arm element 30.
  • arm element 30 means, in the context of the present disclosure, an element having a prevailing direction of extension; for example the arm element 30 is a rod or bar element.
  • the arm element 30 has an end 30a rotatably associated with the first wall 101 and with the second wall 102 of the profiled element 10 to define a hinge portion 40.
  • the end 30a of the arm element 30 is coupled to the first wall 101 and to the second wall 102 of the profiled element 10 so as to be able to rotate with respect to these.
  • the articulated mechanism 1 further comprises a first lining element 21 and a second lining element 22, associated respectively with the first wall 101 and the second wall 102 at the end region 10a of the profiled element 10.
  • the first lining element 21 comprises a protective wall 211 interposed between the arm element 30 and the first wall 101 in such a way as to prevent contact between them and the second lining element 22 comprises a protective wall 221 interposed between the arm element 30 and the second wall 102 in such a way as to prevent contact between them.
  • the protective wall 211 of the first lining element 21 and the protective wall 221 of the second lining element 21 are interposed between the arm element 30 and, respectively, the first wall 101 of the profiled element 10 and the second wall 102 of profiled element 10. In this way, contact between the arm element 30 and the profiled element 10 is prevented. It therefore follows that, in use, during the movement of the arm element 30 with respect to the profiled element 10, the surfaces of these elements, not being in direct contact with each other, cannot be subjected to friction.
  • the profiled element 10 is also a substantially rod-shaped element, that is, having a prevailing direction of extension.
  • the profiled element has a section in the shape of a "C", that is "U”, or in the shape of an "H” for its entire extension along the prevailing direction of extension.
