Description

La présente invention est relative à un mécanisme d'articulation pour un lit-divan.The present invention relates to a hinge mechanism for a sofa bed.

Le but de l'invention est de réaliser un mécanisme d'articulation qui puisse être monté aux extrémités des cadres formant siège et dossier dans un lit-divan ou un meuble analogue, mécanisme dont les éléments ne dépassent pas le niveau du matelas ou de l'équipement analogue disposés sur les cadres formant siège et dossier.The object of the invention is to provide an articulation mechanism which can be mounted at the ends of the seat and back frames in a sofa bed or the like, a mechanism the elements of which do not exceed the level of the mattress or the 'analogous equipment arranged on the seat and back frames.

A cet effet, le mécanisme d'articulation selon l'invention comprend des cornières articulées entre elles et supportant chacune un cadre appartenant l'un aux éléments formant dossier et l'autre aux éléments formant siège, les deux cornières étant reliées d'autre part à une traverse du chassîs par des leviers montés à charnière: à leurs extrémités, d'une part sur ladite traverse et, d'autre part, sur chacune des cornières, un ressort de rappel étant prévu pour ramener le mécanisme d'articulation dans la position dans laquelle les deux cidres précités forment un divan.To this end, the articulation mechanism according to the invention comprises angle brackets hinged together and each supporting a frame belonging one to the backrest elements and the other to the seat elements, the two angles being connected on the other hand to a cross member of the chassîs by hinged levers: at their ends, on the one hand on said cross member and, on the other hand, on each of the angles, a return spring being provided to bring the articulation mechanism back into the position in which the two aforementioned ciders form a couch.

. D'autres détails et avantages de l'invention ressortiront de la description qui sera donnée ci-après d'un mécanisme d'articulation pour un lit-divan selon l'invention. Cette description n'est donnée qu'à titre d'exemple et ne limite pas l'invention. Les notations de référence se rapportent aux figures ci-jointes.

  • La figure 1 montre en perspective, avec brisures partielles, e mécanisme d'articulation et les éléments de cadre qui lui sont ass )ciés, dans la position "divan".
  • La figure 2 montre, également en perspective, et avec brisures partielles, le mécanisme d'articulation dans la position "lit".
. Other details and advantages of the invention will emerge from the description which will be given below of an articulation mechanism for a sofa bed according to the invention. This description is given by way of example only and does not limit the invention. The reference notations refer to the attached figures.
  • Figure 1 shows in perspective, with partial breaks, e hinge mechanism and the frame elements which are ass) ciés, in the position "couch".
  • Figure 2 shows, also in perspective, and with partial breaks, the articulation mechanism in the "bed" position.

Le mécanisme d'articulation selon l'invention comprend essentiellement deux cornières 1 et 2 qui sont montées à pivotement en 3. A la cornière 1 est fixé le cadre 4 qui est un élément du dossier tandis qu'à la cornière 2 est fixé le cadre 5 et qui constitue un élément du siège.The articulation mechanism according to the invention essentially comprises two angles 1 and 2 which are pivotally mounted at 3. At the angle 1 is fixed the frame 4 which is an element of the backrest while at the angle 2 is fixed the frame 5 and which constitutes an element of the seat.

En dehors de leur articulation commune en 3, les cornières 1 et 2 sont encore reliées à une traverse T qui se fixe sur le chassîs du lit-divan. Cette liaison à charnières se fait par des leviers 6, 7 et 8.Apart from their common articulation at 3, the angles 1 and 2 are still connected to a cross-member T which is fixed on the chasis of the sofa bed. This hinged connection is made by levers 6, 7 and 8.

Les points d'articulation du levier 6 par rapport à la cornière 1 et à la traverse 4 se trouvent en 9 et 10. Les points d'articulation du levier 7 par rapport à ces mêmes éléments sont 11 et 12. La cornière 2 n'est articulée à la traverse T que par le seul levier 8 dont les points d'articulation sont 13 et 14 respectivement.The points of articulation of the lever 6 with respect to the angle 1 and the cross-member 4 are located at 9 and 10. The points of articulation of the lever 7 with respect to these same elements are 11 and 12. The angle 2 is articulated to the cross-member T only by the single lever 8 whose articulation points are 13 and 14 respectively.

Un ressort de rappel 15 est tendu entre un point 16 de la traverse T et un point 17 du levier 8.A return spring 15 is tensioned between a point 16 of the cross-member T and a point 17 of the lever 8.

Le mouvement de basculement vers la position siège du mécanisme est limité par un un ergot saillant 18 prévu sur la face extérieure de la cornière 2 et disposé à un endroit tel qu'il vient buter contre le levier 7 lorsque le mécanisme se trouve dans la position siège, c.à.d. la position représentée à la figure 1.The tilting movement towards the seat position of the mechanism is limited by a protruding lug 18 provided on the outer face of the angle iron 2 and disposed in a place such that it abuts against the lever 7 when the mechanism is in the position headquarters, i.e. the position shown in Figure 1.

De la description qui vient d'être donnée et de la lecture des figures, on remarque que tout le mécanisme d'articulation et principalement les cornières 1 en 2, ne dépasse jamais le niveau du matelas dont est équipé un lit-divan auquel le mécanisme d'articulation selon l'invention est destiné.From the description which has just been given and from the reading of the figures, it will be noted that the whole articulation mechanism and mainly the angles 1 in 2, never exceeds the level of the mattress with which a sofa bed is equipped with which the mechanism articulation according to the invention is intended.
