Description

Cette invention concerne un mécanisme d'articulation permettant l'installation dans au moins deux positions extrêmes et une série de positions intermédiaires de deux éléments d'un siège ou divan, constitués d'un premier cadre formant siège et d'un second cadre formant dossier, chacun de ces cadres formant siège et dossier étant reliés à pivotement par des leviers à une traverse appartenant au chassis de support du siège ou du divan.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.

Des mécanismes de l'espèce sont connus.Mechanisms of the species are known.

En raison de leur encombrement et de la continuité des leviers s'étendant sensiblement dans le même plan, jusqu'ici, il était nécessaire d'interrompre les longerons de base de chacun des cadres précités pour permettre aux divers leviers formant articulation de se deplacer au cours des mouvements imprimés à chacun des cadres formant siège et dossier.Due to their size and the continuity of the levers extending substantially in the same plane, hitherto, it was necessary to interrupt the base beams of each of the aforementioned frames to allow the various levers forming articulation to move to the course of movements printed on each of the frames forming seat and back.

Pour cette même raison, l'articulation ne peut jamais être éloignée des extrémités latérales du siège ou du divan. Ceci est naturellement très gênant lorsqu'il s'agit d'un lit-divan où il n'est pas possible de tolérer la présence de pièces d'articulation au-dessus du plan général horizontal occupé par le cadre formant siège et par le cadre formant dossier lorsque celui-ci est rabattu dans ce plan horizontal.For this same reason, 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.

L'invention a pour but de remédier à ces inconvénients et de proposer une articulation d'un type nouveau et original qui permet l'utilisation de cadres non interrompus, c.à.d. de cadres standard qui ne doivent pas être modifiés pour être incorporés dans la structure d'un siège, d'un sofa ou d'un lit-divan.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.

A cet effet, des cornières auxquelles sont fixés le cadre formant siège et le cadre formant dossier sont, en dehors de leur liaison à pivotement avec la traverse précitée, grâce aux leviers susdits, reliées entre elles par un jeu de leviers coudés ayant entre eux un point d'articulation et, au delà de ce point d'articulation, une seconde liaison à charnière à l'aide de leviers reliant cinématiquement entre elles les cornières précitées.For this purpose, 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.

Toujours selon l'invention, chacun des leviers coudés précités présente une forme arquée de manière telle que les longerons, tant du cadre appartenant au siège que du cadre appartenant au dossier puissent croiser le plan dans lequel travaille le mécanisme d'articulation.Still according to the invention, 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.

D'autres détails et avantages de l'invention ressortiront de la description qui sera donnée ci-après d'un mécanisme d'articulation d'un siège ou d'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, selon une vue en perspective, avec brisures partielles le mécanisme d'articulation dans la position "divan".
  • La figure 2 est une vue en perspective, avec brisures partielles d'un mécanisme d'articulation en 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 seat or 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 a perspective view, with partial breaks the hinge mechanism in the "couch" position.
  • Figure 2 is a perspective view, partially broken of an articulation mechanism in the "bed" position.

Aux figures 1 et 2 on remarque plusieurs éléments appartenant aux cadres 1 et 2. Le cadre 1 constitue essentiellement le dossier tandis que le cadre 2 constitue le siège. Au cadre 1 appartiennent les longerons 3 et les traverses 4 tandis qu'au cadre 2 appartiennent les longerons 3' et les traverses 4'.In Figures 1 and 2 there are several elements belonging to frames 1 and 2. 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'.

A une des traverses 4 du cadre 1 est fixée la cornière 5 tandis qu'une cornière analogue 6 est fixée à une traverse 4' du cadre 2.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.

Un objet précis de l'invention est de pouvoir fixer ces cornières 5 et 6 non pas aux extrémités des cadres 1 et 2, mais à n'importe quelle traverse 4 sans devoir interrompre l'un des longerons 3 ou 3'.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 '.

La cornière 5 est articulée par un levier 7 à la traverse 8 qui constitue un élément qui se fixe au chassis du lit-divan. Le levier 7 est articulé en 9 à la cornière 5 et en 10 sur la traverse 8.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.

L'autre cornière, 6, est articulée par des leviers 11 et 12 sur la même traverse 8. Les points d'articulation des leviers 11 et 12 par rapport à la cornière 6 sont situés en 13 et 14. Les points d'articulation par rapport à la traverse 8 sont situés en 15 et 16. Un ressort de rappel 18 est fixé en 19 sur le levier 12, d'une part, et en 20 sur l'extrémité inférieure du levier 7.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.

D'autre part, un mécanisme à cliquets 21, d'un type connu, est monté à articulation entre un point 22, situé sur la traverse 8 et un point 23, situé sur le levier 12.On the other hand, 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.

En dehors des leviers 7, 11 et 12 décrits ci-dessus, le mécanisme d'articulation selon l'invention est essentiellement caractérisé par la présence des leviers coudés 24 et 25. Ces leviers coudés fortement arqués permettent, comme le montrent les figures, le passage des longerons 3 et 3' de telle sorte que tout le mécanisme d'articulation peut se monter sur une autre traverse 4 ou 4' que les traverses d'extrémité des cadres 1 et 2. Les leviers coudés 24 et 25 ont un point de pivotement commun entre eux 26. Ils sont articulés à une extrémité en 27 sur la cornière 5 et en 28 sur la cornière 6.Apart from the levers 7, 11 and 12 described above, 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.

A leur extrémité opposée les mêmes leviers coudés 24 et 25 sont articulés en 29 et 30 sur des leviers 31 et 32 qui sont eux-mêmes articulés en 33 et 34 sur les cornières 6 et 5 respectivement. Une butée 17 fixée sur la traverse 8 limite la course du levier coudé 24 qui vient heurter avec sa partie inférieure la butée en question.At their opposite end, the same 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.

De la description qui vient d'être donnée et de la lecture des figures résulte très clairement le grand intérêt du mécanisme d'articulation selon l'invention, puisque ce mécanisme permet le montage, à tout endroit des cadres 1 et 2, des cornières 5 et 6. Celles-ci ne doivent plus être fixées aux traverses d'extrémités comme cela a déjà été souligné plus haut. Il n'est plus nécessaire non plus d'interrompre à proximité de leurs extrémités, les longerons 3 et 3' si l'on veut disposer le mécanisme à l'intérieur des cadres 1 et 2.From the description which has just been given and from the reading of the figures very clearly results the great interest of the articulation mechanism according to the invention, since this mechanism allows the mounting, at any place of the frames 1 and 2, of the angles 5 and 6. These must no longer be fixed to the end crosspieces as has already been pointed out above. It is no longer necessary either to interrupt, near their ends, the side members 3 and 3 ′ if the mechanism is to be placed inside the frames 1 and 2.
