Definitions

  • This invention relates to an articulation mechanism allowing the installation in at least two extreme positions and a series of intermediate positions of two elements of a seat or sofa, consisting of a first frame forming a seat and a second frame forming a backrest. , each of these seat and backrest frames being pivotally connected by levers to a cross member belonging to the support frame of the seat or the couch.
  • the joint can never be moved away from the lateral ends of the seat or the sofa. This is naturally very annoying when it is a sofa bed where it is not possible to tolerate the presence of articulation parts above the general horizontal plane occupied by the seat frame and by the frame forming a backrest when the latter is folded down in this horizontal plane.
  • the object of the invention is to remedy these drawbacks and to propose an articulation of a new and original type which allows the use of uninterrupted frames, i.e. standard frames which must not be modified to be incorporated into the structure of a seat, sofa or sofa bed.
  • angles which are fixed, the seat-forming frame and the back-forming frame are, apart from their pivoting connection with the aforementioned cross-member, by virtue of the abovementioned levers, connected to one another by a set of bent levers having between them a point of articulation and, beyond from this articulation point, a second hinged connection using levers kinematically connecting the above-mentioned angles.
  • each of the above-mentioned bent levers has an arcuate shape so that the side members, both of the frame belonging to the seat and of the frame belonging to the backrest, can cross the plane in which the articulation mechanism works.
  • Frame 1 essentially constitutes the backrest while frame 2 constitutes the seat.
  • To frame 1 belong the side members 3 and the cross members 4 while to frame 2 belong the side members 3 'and the cross members 4'.
  • angle iron 5 To one of the crosspieces 4 of the frame 1 is fixed the angle iron 5 while a similar angle iron 6 is fixed to a crosspiece 4 'of the frame 2.
  • a specific object of the invention is to be able to fix these angles 5 and 6 not to the ends of the frames 1 and 2, but to any cross member 4 without having to interrupt one of the side members 3 or 3 '.
  • the angle 5 is articulated by a lever 7 to the cross member 8 which constitutes an element which is fixed to the frame of the sofa bed.
  • the lever 7 is articulated at 9 to the angle 5 and at 10 on the cross-member 8.
  • the other angle, 6, is articulated by levers 11 and 12 on the same cross member 8.
  • the points of articulation of the levers 11 and 12 relative to the angle 6 are located at 13 and 14.
  • the points of articulation by relative to the cross-member 8 are located at 15 and 16.
  • a return spring 18 is fixed at 19 to the lever 12, on the one hand, and at 20 to the lower end of the lever 7.
  • a ratchet mechanism 21 of a known type, is mounted at articulation between a point 22, located on the cross-member 8 and a point 23, located on the lever 12.
  • the articulation mechanism according to the invention is essentially characterized by the presence of the angled levers 24 and 25.
  • These strongly arched angled levers allow, as the figures show, the passage of the side members 3 and 3 'so that the entire articulation mechanism can be mounted on another cross member 4 or 4' than the end cross members of the frames 1 and 2.
  • the bent levers 24 and 25 have a point of common pivot between them 26. They are articulated at one end at 27 on the angle 5 and at 28 on the angle 6.
  • bent levers 24 and 25 are articulated at 29 and 30 on levers 31 and 32 which are themselves articulated at 33 and 34 on the angles 6 and 5 respectively.
  • a stop 17 fixed on the cross member 8 limits the travel of the bent lever 24 which strikes with its lower part the stop in question.
