Definitions

  • the present invention relates to a folding chair occupying, in the folded position, a volume whose height is reduced to that of its rear leg and whose thickness is limited to the added widths of the sides of said leg and the backrest.
  • the invention relates to a folding chair of the kind comprising a seat, for example of rectangular or square shape, a U-shaped back attached to the opposite sides of this seat by means of its branches and by means of 'joints, a U-shaped front foot, secured to opposite sides of the rear part of said seat, by means of its branches and by means of joints, and a rear foot comprising two parallel branches braced and attached, by l 'intermediate of its branches and by means of joints, on the one hand, at the lower end of the branches of said backrest and, on the other hand, to the branches of said front leg.

  • Such a folding chair which is extremely simple and occupies, in the folded position, a volume reduced to a minimum, has the disadvantage of not being able to overcome a uniformity due to the fact that the forms of its various constituent elements are imposed by the necessity of their embedding in each other to bring them back in the same plane.
  • folding chair which occupies, in the folded position, a relatively large volume whose height takes into account the depth of the seat and the height of the backrest and whose thickness comprises three stages consisting of the added thicknesses of the backrest, seat and rear leg .

  • this object is obtained thanks to a folding chair of this type which is notably remarkable by the fact that it comprises, in the direction of its thickness, after folding, only two stages, that is to say a first stage constituted by the seat surrounded on three sides by the backrest, and a second stage consisting of the front leg surrounding the rear leg.
  • a folding chair is obtained, the volume of which has a reduced height and thickness, in the folded position, and allowing a greater diversity of forms for the production of its constituent elements.
  • the chair has two right and left metal frames constituted by four fittings assembled by means of joints, so as to constitute a deformable quadrilateral and on which are respectively fixed, for example by screwing, the seat, the backrest, the front foot and the rear foot of said chair ; the axes of articulation of these reinforcements corresponding, respectively, to the axes of articulation of the above-mentioned constituent elements of the latter.
  • the metal reinforcements can be produced separately and economically, in flat irons, by means of automatic machines which are not very complex.
  • To build the chair it then suffices to glue, screw or rivet, on the four flat bars constituting said frames, the four constituent elements of the chair: the seat, the backrest, the front foot and the rear foot, respectively, which can , therefore, be made in very different materials and shapes, which allows to obtain a wide variety of conformations of chairs from standard frames.
  • This chair can be made of any material with the required rigidity and solidity, used alone or in combinations. It mainly includes: - A seat 1 which can have different dimensions and shapes and, for example, a rectangular or square shape; - a file 2 having a general U shape; - a rear leg 3 consisting of two braced branches; - And a front leg 4 having a U shape or substantially.

Description

La présente invention concerne une chaise pliante occupant, en position repliée, un volume dont la hauteur est réduite à celle de son pied arrière et dont l'épaisseur est limitée aux largeurs additionnées des côtés dudit pied et du dossier.The present invention relates to a folding chair occupying, in the folded position, a volume whose height is reduced to that of its rear leg and whose thickness is limited to the added widths of the sides of said leg and the backrest.

Plus précisément, l'invention se rattache à une chaise pliante du genre comprenant un siège, par exemple de forme rectangulaire ou carrée, un dossier en forme de U rattaché aux côtés opposés de ce siège par l'intermédiaire de ses branches et au moyen d'articula­tions, un pied avant en forme de U, assujetti aux côtés opposés de la partie postérieure dudit siège, par l'intermédiaire de ses branches et au moyen d'arti­culations, et un pied arrière comprenant deux branches parallèles entretoisées et rattaché, par l'intermé­diaire de ses branches et au moyen d'articulations, d'une part, à l'extrémité inférieure des branches dudit dossier et, d'autre part, aux branches dudit pied avant.More specifically, the invention relates to a folding chair of the kind comprising a seat, for example of rectangular or square shape, a U-shaped back attached to the opposite sides of this seat by means of its branches and by means of 'joints, a U-shaped front foot, secured to opposite sides of the rear part of said seat, by means of its branches and by means of joints, and a rear foot comprising two parallel branches braced and attached, by l 'intermediate of its branches and by means of joints, on the one hand, at the lower end of the branches of said backrest and, on the other hand, to the branches of said front leg.

Des chaises pliantes de ce genre sont, par exemple, décrites dans la Demande de Brevet français N, 86/13244 et dans le document FR-A-1.510.290.Folding chairs of this kind are, for example, described in French Patent Application N, 86/13244 and in document FR-A-1,510,290.

Dans la Demande de Brevet français N, 86/13244, est décrite une chaise pliante occupant, en position repliée, un volume extrêmement réduit dont la hauteur est donnée par la longueur du pied avant et dont l'épaisseur correspond à la largeur des côtés de ces derniers.In French Patent Application N, 86/13244, a folding chair is described occupying, in the folded position, an extremely reduced volume whose height is given by the length of the front leg and whose thickness corresponds to the width of the sides of these latter.

Une telle chaise pliante qui est extrêmement simple et occupe, en position repliée, un volume réduit au minimum, a cependant pour inconvénient de ne pas pouvoir s'affranchir d'une uniformité due au fait que les formes de ses différents éléments constitutifs sont imposées par la nécessité de leur encastrement les uns dans les autres pour les ramener dans un même plan.Such a folding chair which is extremely simple and occupies, in the folded position, a volume reduced to a minimum, has the disadvantage of not being able to overcome a uniformity due to the fact that the forms of its various constituent elements are imposed by the necessity of their embedding in each other to bring them back in the same plane.

Dans le document FR-A-1.510.290, est décrite une chaise pliante qui occupe, en position repliée, un volume relativement important dont la hauteur prend en compte la profondeur du siège et la hauteur du dossier et dont l'épaisseur comprend trois étages constitués par les épaisseurs additionnées du dossier, du siège et du pied arrière. Un autre inconvénient d'une telle chaise découle du fait que les articulations du siège par rapport au dossier et au pied arrière sont réalisées au moyen de chapes dont la présence exclut, pratiquement, toute possibilité de réaliser l'ossature de ladite chaise dans un matériau autre que le métal. En outre, la limitation du basculement du dossier vers l'arrière, dans la position de dépliage, est obtenue par butée de la face supérieure de la partie postérieure de l'armature du siège contre le bord inférieur du fond de la chape, ce qui entraîne l'endommagement de ladite face supérieure visible.In document FR-A-1.510.290, a description is given folding chair which occupies, in the folded position, a relatively large volume whose height takes into account the depth of the seat and the height of the backrest and whose thickness comprises three stages consisting of the added thicknesses of the backrest, seat and rear leg . Another drawback of such a chair results from the fact that the articulations of the seat with respect to the backrest and the rear leg are produced by means of screeds, the presence of which virtually excludes any possibility of making the frame of said chair in a material other than metal. In addition, the limitation of the backrest tilting in the unfolding position is obtained by abutment of the upper face of the rear part of the seat frame against the lower edge of the bottom of the yoke, which causes damage to said visible upper face.

La présente invention a plus particulièrement pour but de remédier aux inconvénients ou insuffisances des chaises pliantes du genre susmentionné et notamment décrites dans la Demande de Brevet français N, 86/13244 et dans le document FR-A-1.510.290.The present invention more particularly aims to remedy the drawbacks or inadequacies of folding chairs of the aforementioned kind and in particular described in French Patent Application N, 86/13244 and in document FR-A-1,510,290.

Selon l'invention, ce but est obtenu grâce à une chaise pliante de ce type qui est notamment remarquable par le fait qu'elle comporte, dans le sens de son épaisseur, après pliage, seulement deux étages, soit un premier étage constitué par le siège entouré sur trois côtés par le dossier, et un deuxième étage constitué par le pied avant entourant le pied arrière.According to the invention, this object is obtained thanks to a folding chair of this type which is notably remarkable by the fact that it comprises, in the direction of its thickness, after folding, only two stages, that is to say a first stage constituted by the seat surrounded on three sides by the backrest, and a second stage consisting of the front leg surrounding the rear leg.

Grâce à cette disposition, on obtient une chaise pliante dont le volume présente une hauteur et une épaisseur réduites, en position repliée, et permettant une plus grande diversité de formes pour la réalisation de ses éléments constitutifs.Thanks to this arrangement, a folding chair is obtained, the volume of which has a reduced height and thickness, in the folded position, and allowing a greater diversity of forms for the production of its constituent elements.

Selon une autre disposition caractéristique importante de l'invention, la chaise comporte deux armatures métalliques droite et gauche constituées par quatre ferrures assemblées au moyen d'articulations, de manière à constituer un quadrilatère déformable et sur lesquelles sont respectivement fixés, par exemple par vissage, le siège, le dossier, le pied avant et le pied arrière de ladite chaise ; les axes d'articulation de ces armatures correspondant, respectivement, aux axes d'articulation des éléments constitutifs susmentionnés de cette dernière.According to another important characteristic arrangement of the invention, the chair has two right and left metal frames constituted by four fittings assembled by means of joints, so as to constitute a deformable quadrilateral and on which are respectively fixed, for example by screwing, the seat, the backrest, the front foot and the rear foot of said chair ; the axes of articulation of these reinforcements corresponding, respectively, to the axes of articulation of the above-mentioned constituent elements of the latter.

Grâce à cette construction, les armatures métalliques peuvent être réalisées séparément et de manière économique, en fers plats, au moyen de machines automatiques peu complexes. Pour construire la chaise, il suffit ensuite de coller, visser ou riveter, sur les quatre fers plats constituant lesdites armatures, les quatre éléments constitutifs de la chaise : le siège, le dossier, le pied avant et le pied arrière, respec­tivement, lesquels peuvent, de ce fait, être réalisés dans des matériaux et des formes très divers, ce qui permet d'obtenir une grande variété de conformations de chaises à partir d'armatures standard.Thanks to this construction, the metal reinforcements can be produced separately and economically, in flat irons, by means of automatic machines which are not very complex. To build the chair, it then suffices to glue, screw or rivet, on the four flat bars constituting said frames, the four constituent elements of the chair: the seat, the backrest, the front foot and the rear foot, respectively, which can , therefore, be made in very different materials and shapes, which allows to obtain a wide variety of conformations of chairs from standard frames.

On se reporte auxdits dessins pour décrire des exemples de réalisation intéressants, bien que nullement limitatifs, de la chaise pliante selon l'invention.Reference is made to said drawings to describe interesting, although in no way limiting, embodiments of the folding chair according to the invention.

Cette chaise peut être exécutée en tous matériaux présentant la rigidité et la solidité requises, utilisés seuls ou en combinaisons. Elle comprend principalement :
- un siège 1 qui peut avoir différentes dimensions et formes et, par exemple, une forme rectangulaire ou carrée ;
- un dossier 2 ayant une forme générale en U ;
- un pied arrière 3 constitué de deux branches entretoisées ;
- et un pied avant 4 ayant une forme en U ou sensiblement.This chair can be made of any material with the required rigidity and solidity, used alone or in combinations. It mainly includes:
- A seat 1 which can have different dimensions and shapes and, for example, a rectangular or square shape;
- a file 2 having a general U shape;
- a rear leg 3 consisting of two braced branches;
- And a front leg 4 having a U shape or substantially.

Le dossier 2 est fixé, par l'intermédiaire de ses branches latérales 2a et au moyen d'articulations comprenant un axe 5, sur la partie postérieure de chaque côté du siège 1, à distance du bord arrière de celui-ci.File 2 is fixed, through its lateral branches 2a and by means of articulations comprising an axis 5, on the rear part of each side of the seat 1, at a distance from the rear edge of the latter.

Les axes d'articulation 5 assurent une liaison directe entre le siège 1 et le dossier 2 et se trouvent compris à la fois dans le plan du siège et dans le plan du dossier, de sorte que, dans la position de pliage, ledit siège peut venir se loger à l'intérieur du U constitué par ledit dossier et dans le plan de celui-ci, de façon à former l'un des étages ou niveaux de la chaise en position pliée.The hinge pins 5 provide a direct connection between the seat 1 and the backrest 2 and are included both in the seat plane and in the backrest plane, so that, in the folding position, said seat can come to be housed inside the U formed by said backrest and in the plane thereof, so as to form one of the floors or levels of the chair in the folded position.

Le pied avant 4 est fixé, par l'intermédiaire de l'extrémité de ses branches latérales 4a et au moyen d'articulations comprenant un axe 6, à l'extrémité postérieure de chacun des côtés du siège, en arrière de l'articulation 5 reliant celui-ci au dossier 2.The front leg 4 is fixed, by means of the end of its lateral branches 4a and by means of articulations comprising an axis 6, at the rear end of each of the sides of the seat, behind the articulation 5 linking it to file 2.

Les branches latérales 2a du dossier 2 et les branches latérales 4a du pied avant 4 sont disposées dans les mêmes plans verticaux et l'axe d'articulation 6 desdites branches du pied avant sur le siège est disposé dans le plan de l'un de ces deux éléments seulement. Selon l'exemple illustré,l'axe 6 est disposé dans le plan des branches 4a du pied avant, cet axe étant, d'autre part, porté par une patte 7 disposée au-dessous du plan dans lequel est compris le siège 1 et rigidement solidaire de ce dernier.The lateral branches 2a of the backrest 2 and the lateral branches 4a of the front leg 4 are arranged in the same vertical planes and the articulation axis 6 of said branches of the front leg on the seat is arranged in the plane of one of these two elements only. According to the example illustrated, the axis 6 is disposed in the plane of the branches 4a of the front leg, this axis being, on the other hand, carried by a lug 7 disposed below the plane in which the seat 1 is included and rigidly attached to the latter.

Le pied arrière 3 est rattaché, par l'intermédiaire de ses branches latérales 3a :
- d'une part, au moyen d'articulations comprenant un axe 8, à l'extrémité inférieure des branches 2a du dossier 2, et,
- d'autre part, au moyen d'articulations comprenant un axe 9, à une partie intermédiaire des branches 4a du pied avant 4.The rear leg 3 is attached, by means of its lateral branches 3a:
on the one hand, by means of articulations comprising an axis 8, at the lower end of the branches 2a of the backrest 2, and,
- on the other hand, by means of articulations comprising an axis 9, at an intermediate part of the branches 4a of the front leg 4.

Les articulations 8 du pied arrière 3 et du dossier 2 sont disposées à faible distance du sommet des branches 3a dudit pied, de sorte qu'une courte portion 3b desdites branches se trouve disposée au-dessus desdites articulations. Ce prolongement 3b prend appui, par l'intermédiaire de son extrémité libre, contre la surface inférieure du siège 1 et constitue ainsi une butée limitant le pivotement des éléments constitutifs de la chaise, dans la position d'ouverture. Cette butée est, de par sa constitution, son emplacement et son mode d'action, particulièrement simple et solide, et elle contribue à une bonne stabilité de la chaise.The joints 8 of the rear foot 3 and the folder 2 are arranged a short distance from the top of the branches 3a of said foot, so that a short portion 3b of said branches is disposed above said joints. This extension 3b is supported, through its free end, against the lower surface of the seat 1 and thus constitutes a stop limiting the pivoting of the constituent elements of the chair, in the open position. This stop is, by its constitution, its location and its mode of action, particularly simple and solid, and it contributes to a good stability of the chair.

Les axes d'articulation 8 du dossier 2 sur le pied arrière 3, sont disposés dans le plan de l'un de ces deux éléments seulement. Selon l'exemple illustré, ces axes 8 sont disposés dans le plan du pied 3, chacun desdits axes étant, d'une part, porté par une patte 10 solidaire de la branche considérée 2a du dossier et déportée latéralement par rapport à ladite branche. L'articulation des pieds avant 4 et arrière 3 par l'intermédiaire des pattes 7 et 10, respectivement, permet, lors du pliage de la chaise, de plaquer ce dernier contre la face inférieure du siège 1, ledit pied avant venant entourer ledit pied arrière sur ses trois faces extérieures, en constituant ainsi le deuxième étage ou niveau que présente ladite chaise en position repliée. Les figures 2 et 4 montrent bien cette conformation de la chaise en position repliée laquelle est constituée par la superposition de deux étages dont l'un est constitué par le siège 1 entouré, sur trois de ses faces, par le dossier 2, et dont l'autre est constitué par le pied arrière 3 entouré, sur ses trois faces externes, par le pied avant 4. On voit, sur ces figures, que, dans la position de pliage, la chaise présente un volume réduit dont la hauteur est limitée à la hauteur de son pied avant et dont l'épaisseur est réduite à la superposition des deux étages précédemment décrits.The hinge pins 8 of the backrest 2 on the rear leg 3, are arranged in the plane of only one of these two elements. According to the example illustrated, these axes 8 are arranged in the plane of the leg 3, each of said axes being, on the one hand, carried by a lug 10 secured to the branch considered 2a of the backrest and offset laterally relative to said branch. The articulation of the front 4 and rear 3 legs via the legs 7 and 10, respectively, makes it possible, when folding the chair, to press the latter against the underside of the seat 1, said front foot coming to surround said foot rear on its three outer faces, thus constituting the second floor or level that said chair has in the folded position. Figures 2 and 4 clearly show this configuration of the chair in the folded position which is constituted by the superposition of two floors, one of which is constituted by the seat 1 surrounded, on three of its faces, by the backrest 2, and whose l other is constituted by the rear leg 3 surrounded, on its three external faces, by the front leg 4. It can be seen in these figures that, in the folding position, the chair has a reduced volume whose height is limited to the height of his front foot and whose the thickness is reduced to the superposition of the two stages previously described.

La figure 5 illustre une autre disposition caractéristique importante de l'invention suivant laquelle la chaise comporte deux armatures métalliques droite et gauche sur lesquelles sont fixés les quatre éléments constitutifs de ladite chaise et grâce auxquelles ces derniers sont assemblés de manière articulée.FIG. 5 illustrates another important characteristic arrangement of the invention according to which the chair comprises two right and left metal frames on which the four constituent elements of said chair are fixed and by means of which the latter are assembled in an articulated manner.

Chacune de ces armatures comprend quatre ferrures 1′, 2′, 3′, 4′ assemblées au moyen d'articula­tions, de manière à constituer un quadrilatère déformable, et sur lesquelles sont respectivement fixés, par exemple par vissage,le siège 1, le dossier 2, le pied arrière 3 et le pied avant 4, de la chaise. Ces ferrures présentent une longueur réduite par rapport aux côtés des éléments constitutifs de la chaise sur lesquels elles sont fixées.Each of these frames includes four fittings 1 ′, 2 ′, 3 ′, 4 ′ assembled by means of articulations, so as to constitute a deformable quadrilateral, and on which are respectively fixed, for example by screwing, the seat 1, the backrest 2, the rear leg 3 and the front leg 4, of the chair. These fittings have a reduced length relative to the sides of the components of the chair on which they are fixed.

Les axes d'articulations 5, 6, 8 et 9 de ces ferrures constituées par des fers plats, correspondent aux axes d'articulation précédemment décrits des différents éléments constitutifs de la chaise.The axes of articulations 5, 6, 8 and 9 of these fittings constituted by flat bars, correspond to the previously described articulation axes of the various constituent elements of the chair.

Chaque ferrure de siège 1′ est fixée sur la partie postérieure 1˝ de la face latérale considérée du siège 1 et elle s'articule, d'une part, par l'intermédiaire de l'une de ses portions terminales et au moyen de l'axe 5, sur la ferrure 2′ et, d'autre part, par l'intermédiaire de la patte 7 dont est munie son extrémité opposée et de l'axe 6, sur la ferrure 4′.Each seat fitting 1 ′ is fixed to the rear part 1˝ of the lateral face considered of the seat 1 and it is articulated, on the one hand, by means of one of its terminal portions and by means of the 'axis 5, on the fitting 2' and, on the other hand, by means of the tab 7 with which its opposite end is provided and of the axis 6, on the fitting 4 '.

Chaque ferrure de dossier 2′ est fixée sur la portion inférieure 2˝ de la face interne de la branche 2a considérée du dossier 2 et elle s'articule, d'une part, par l'intermédiaire de sa partie intermédiaire et au moyen de l'axe 5, sur la ferrure 1′ et, d'autre part, par l'intermédiaire de la patte 10 dont est munie l'une de ses extrémités et de l'axe 8, sur la ferrure 3′.Each backrest fitting 2 ′ is fixed to the lower portion 2˝ of the internal face of the branch 2a considered of the backrest 2 and it is articulated, on the one hand, through its intermediate part and by means of the 'axis 5, on the fitting 1' and, on the other hand, by means of the tab 10 which is provided with one of its ends and of the axis 8, on the fitting 3 ′.

Chaque ferrure de pied arrière 3′ est fixée sur la portion supérieure 3˝ de la face latérale considérée du pied arrière 3 et elle s'articule, d'une part, au moyen de l'une de ses extrémités et de l'axe 8, sur la patte 10 de la ferrure 2′ et, d'autre part, au moyen de sa portion intermédiaire et de l'axe 9, sur la ferrure 4′.Each rear leg fitting 3 ′ is fixed to the upper portion 3˝ of the lateral face considered of the rear leg 3 and it is articulated, on the one hand, by means of one of its ends and of the axis 8 , on the lug 10 of the fitting 2 ′ and, on the other hand, by means of its intermediate portion and the axis 9, on the fitting 4 ′.

Enfin, chaque ferrure de pied avant 4′ est fixée sur la portion supérieure 4˝ de la face interne de la branche 4a considérée du pied avant 4 et elle s'articule, d'une part, au moyen de sa portion intermédiaire et de l'axe 9, sur la ferrure 3′ et, d'autre part, par l'intermédiaire de l'une de ses extrémités et au moyen de l'axe 6, sur la patte 7 dont est munie l'une des extrémités de la ferrure 1′.Finally, each front leg fitting 4 ′ is fixed to the upper portion 4˝ of the internal face of the branch 4a considered of the front leg 4 and it is articulated, on the one hand, by means of its intermediate portion and the 'axis 9, on the fitting 3 ′ and, on the other hand, by means of one of its ends and by means of the axis 6, on the lug 7 with which one of the ends of the fitting 1 ′.

On a représenté notamment aux figures 6 et 7, une variante d'exécution de la chaise pliante dont le siège est agencé pour constituer un petit coffre, les éléments constitutifs de ladite chaise étant en outre conformés et dimensionnés de façon que cette dernière affecte, en position de pliage, la forme générale d'une mallette.There is shown in particular in Figures 6 and 7, an alternative embodiment of the folding chair whose seat is arranged to constitute a small trunk, the components of said chair being further shaped and dimensioned so that the latter affects, in folding position, the general shape of a briefcase.

Sur ces figures, les éléments et organes de la chaise qui remplissent des fonctions identiques à celles qui sont les leurs pour le mode d'exécution illustré aux figures 1 à 5, ont été désignés par les mêmes références.In these figures, the elements and organs of the chair which fulfill functions identical to those which are theirs for the embodiment illustrated in Figures 1 to 5, have been designated by the same references.

Selon le mode d'exécution illustré aux figures 6 et 7, le siège 1 a une profondeur plus importante, tandis que les branches 2a, 3a, 4a, du dossier 2, du pied arrière 3 et du pied avant 4, respectivement, ont des largeurs également plus importantes.According to the embodiment illustrated in Figures 6 and 7, the seat 1 has a greater depth, while the branches 2a, 3a, 4a, of the backrest 2, the rear foot 3 and the front foot 4, respectively, have also wider widths.

En position de pliage, la chaise comporte égale­ment seulement deux étages dont l'un est constitué par la demi-partie supérieure 1a du siège-coffre 1 entourée, sur trois de ses côtés, par le dossier 2 en forme de U et dont l'autre est formé par la demi-partie inférieure 1b dudit siège entourée sur trois de ses côtés par le pied arrière 3 en forme de U, lui-même entouré, sur ses trois faces latérales, par le pied avant 4 en forme de U.In the folding position, the chair also has only two stages, one of which is constituted by the upper half-part 1a of the trunk seat 1 surrounded, on three of its sides, by the U-shaped backrest 2 and the other of which is formed by the lower half-part 1b of said seat surrounded on three of its sides by the rear foot 3 in the form of U, itself even surrounded, on its three lateral faces, by the U-shaped front leg 4.

Les branches latérales 2a et 4a du dossier 2 et du pied avant 4, respectivement, sont disposées dans les mêmes plans verticaux, ledit dossier étant articulé, au moyen de l'axe 5, sur la demi-partie supérieure 1a du siège 1, tandis que ledit pied avant est articulé, au moyen de l'axe 6, sur la demi-partie inférieure 1b dudit siège.The lateral branches 2a and 4a of the backrest 2 and of the front leg 4, respectively, are arranged in the same vertical planes, said backrest being articulated, by means of the axis 5, on the upper half-part 1a of the seat 1, while that said front leg is articulated, by means of axis 6, on the lower half-part 1b of said seat.

Le siège 1 comporte, sur chacun de ses côtés latéraux, une feuillure 1c dont la hauteur correspond à celle de sa demi-partie inférieure et à la largeur des branches 3a du pied arrière 3 ; ces feuillures permettant le logement desdites branches dans la position de pliage de la chaise.The seat 1 comprises, on each of its lateral sides, a rebate 1c whose height corresponds to that of its lower half-part and to the width of the branches 3a of the rear leg 3; these rebates allowing the accommodation of said branches in the folding position of the chair.

Le coffre constitué par le siège 1 est muni d'un couvercle 1d constituant la face supérieure de celui-ci, ce couvercle étant articulé sur le corps du coffre par l'intermédiaire de sa partie arrière, par exemple au moyen d'une charnière 11 fixée sur son bord postérieur et sur la paroi arrière du siège. Le bord antérieur de ce couvercle et la paroi avant du coffre sont équipés des organes complémentaires d'un dispositif de fermeture magnétique connu en soi (non représenté) permettant de maintenir le coffre dans la position de fermeture lors du transport de la chaise repliée sous forme de mallette.The trunk constituted by the seat 1 is provided with a cover 1d constituting the upper face thereof, this cover being articulated on the body of the trunk by means of its rear part, for example by means of a hinge 11 fixed on its rear edge and on the rear wall of the seat. The front edge of this cover and the front wall of the trunk are equipped with complementary members of a magnetic closing device known per se (not shown) enabling the trunk to be kept in the closed position during transport of the folded chair in the form of briefcase.

Le couvercle 1d et l'ouverture 13 délimitée par les trois cotés du dossier, sont conformés et dimensionnés pour autoriser également le basculement dudit couvercle, à travers ladite ouverture, dans la position de pliage de la chaise, afin d'avoir accès au coffre, dans cette position.The cover 1d and the opening 13 delimited by the three sides of the backrest, are shaped and dimensioned to also allow the tilting of the said cover, through the said opening, in the folding position of the chair, in order to have access to the trunk, in this position.

Le dossier 2 et le pied avant 4 sont conformés et dimensionnés de façon que la traverse supérieure 2b dudit dossier et la traverse inférieure 4b dudit pied avant, se trouvent disposées face à face, dans la position de pliage, et occupent, dans cette situation, une position rapprochée permettant de les saisir simultanément à la main, de façon à pouvoir transporter commodément la chaise-coffre ainsi réalisée. Dans ce but, la traverse 2b qui a généralement une forme plate et/ou la traverse 4b qui peut également avoir une telle forme est ou sont munie(s) d'une ouverture allongée 2c et 4c, respectivement, disposée dans le sens trans­versal et permettant de constituer une poignée 12.The backrest 2 and the front leg 4 are shaped and dimensioned so that the upper crossmember 2b of the said backrest and the lower crossmember 4b of the said front leg are placed face to face, in the folding position, and occupy, in this situation, a close position allowing them to be grasped simultaneously by hand, so that the chair-chest thus produced can be conveniently transported. For this purpose, the cross member 2b which generally has a flat shape and / or the cross member 4b which can also have such a shape is or are provided with an elongated opening 2c and 4c, respectively, arranged in the transverse direction and making it possible to constitute a handle 12.

Les extrémités inférieures des branches 4a et 3a du pied avant 4 et du pied arrière 3, respectivement, destinées à prendre appui sur le sol présentent avantageusement des surfaces courbes. Dans la position de pliage, les surfaces d'appui courbes des branches du pied arrière se trouvent orientées en direction de la traverse 4b du pied avant 4 et sont masquées, latérale­ment, par les branches 4a dudit pied ; elles ne sont donc pas visibles.The lower ends of the branches 4a and 3a of the front foot 4 and the rear foot 3, respectively, intended to bear on the ground advantageously have curved surfaces. In the folding position, the curved bearing surfaces of the legs of the rear leg are oriented in the direction of the cross member 4b of the front leg 4 and are hidden, laterally, by the legs 4a of said leg; they are therefore not visible.

L'extrémité inférieure des branches latérales 3a du pied arrière 3 est munie, latéralement, d'une protubérance 3c orientée dans le sens transversal. Lorsque la chaise est repliée, ces protubérances 3c se trouvent placées devant la surface courbe d'appui 4e de l'extrémité inférieure des branches latérales 4a du pied avant (figures 10 et 11).The lower end of the lateral branches 3a of the rear leg 3 is provided, laterally, with a protuberance 3c oriented in the transverse direction. When the chair is folded, these protrusions 3c are placed in front of the curved support surface 4e of the lower end of the lateral branches 4a of the front leg (Figures 10 and 11).

Grâce à cette disposition, les surfaces d'appui de la chaise qui présentent des altérations dues au frottement sur le sol, ne sont pas visibles lorsque la chaise est pliée sous forme de mallette, de sorte que le caractère esthétique de cette dernière reste préservé.Thanks to this arrangement, the bearing surfaces of the chair which have alterations due to friction on the ground, are not visible when the chair is folded in the form of a case, so that the latter's aesthetic character remains preserved.

Un autre mode d'exécution de l'invention compréhensible sans dessins supplémentaires, consiste à articuler le pied arrière directement sous le dossier, ce qui aboutit, après pliage, au fait que le U du pied arrière n'est pas plaqué sous le siège mais sous le U du dossier, tandis que le U du pied avant entoure le U du pied arrière en débordant éventuellement autour du U du dossier. Ce mode d'exécution est plus volumineux que l'autre.Another embodiment of the invention understandable without additional drawings, is to articulate the rear foot directly under the backrest, which results, after folding, in the fact that the U of the rear foot is not pressed under the seat but under the U of the backrest, while the U of the front foot surrounds the U of the rear foot, possibly extending around the U of the backrest. This mode of execution is larger than the other.
