Description

La présente invention concerne un meuble pliant, notamment à usage de chaise.The present invention relates to a folding piece of furniture, in particular for use as a chair.

On connaît de multiples réalisations de chaises pliantes dont la structure articulée a pour but de permettre le repliage de la chaise en vue du rangement.There are many known embodiments of folding chairs whose articulated structure aims to allow the folding of the chair for storage.

Bien souvent, la chaise prend une fois pliée une forme rectangulaire aplatie qui est censée occuper le volume le plus réduit possible en vue du rangement par exemple dans un placard ou local de rangement.Very often, the folded chair takes on a flattened rectangular shape which is supposed to occupy the smallest possible volume for storage, for example in a cupboard or storage room.

Pourtant, même ainsi pliée, la chaise n'est pas toujours facile à ranger. Dans les appartements où les espaces destinés au rangement sont mesurés, il est rare que l'on puisse réserver une grande partie d'un placard à l'entrepôt d'un jeu de chaises pliantes, D'autre part, la chaise ainsi pliée est particulièrement malcommode à manipuler, elle ne tient pas debout sans être appuyée contre un mur, et dans cette position, elle a souvent tendance à glisser puis à tomber. En outre, la forme des chaises pliantes connues, largement conditionnée par leur structure pliante, est généralement peu esthétique.However, even when folded, the chair is not always easy to store. In apartments where the space intended for storage is measured, it is rare that one can reserve a large part of a cupboard in the warehouse of a set of folding chairs, On the other hand, the chair thus folded is particularly awkward to handle, it does not stand upright without being pressed against a wall, and in this position, it often tends to slide and then fall. In addition, the shape of known folding chairs, largely conditioned by their folding structure, is generally unattractive.

On connaît certes d'après le brevet GB-A-1 254 227 un meuble articulé pouvant prendre une position dans laquelle l'un des constituants du meuble est dirigé vers le haut et constitue le dossier d'un fauteuil, et une autre position dans laquelle le même constituant, dirige cette fois vers le bas et reposant sur le sol complète l'assise d'un pouf.Admittedly from GB-A-1 254 227 there is known an articulated piece of furniture which can assume a position in which one of the components of the piece of furniture is directed upwards and constitutes the back of an armchair, and another position in which the same constituent, this time directs down and resting on the ground completes the seat of an ottoman.

Bien entendu, le meuble n'a pas le même forme dans les deux positions, mais aucune d'elles ne conduit à un encombrement réduit ni à un maniement facilité par rapport à l'autre. En fait, il ne s'agit pas d'un meuble pliant mais d'un meuble transformable.Of course, the piece of furniture does not have the same shape in the two positions, but neither of them leads to a reduced bulk nor to an easy handling compared to the other. In fact, it is not a folding piece of furniture but a transformable piece of furniture.

On connaît encore d'après le brevet français 1 166216 un siège pliant comportant un arceau en tube dont les bras coudés sont articulés à l'assise selon un axe situé à mi-chemin entre les pieds antérieurs et postérieurs. Dans une position, l'arceau fait office de dossier et le meuble constitue une chaise tandis que dans l'autre position, l'arceau est rabattu contre les pieds antérieurs, le meuble constituant alors un tabouret.We also know from French patent 1 166216 a folding seat comprising a tube hoop, the bent arms of which are articulated to the seat along an axis located halfway between the front and rear legs. In one position, the hoop acts as a backrest and the piece of furniture constitutes a chair while in the other position, the hoop is folded against the front legs, the piece of furniture then constituting a stool.

L'inconvénient de cette réalisation est que les bras de l'arceau situés le long des bords latéraux de l'assise sont gênants et inesthétiques.The disadvantage of this embodiment is that the arms of the arch located along the side edges of the seat are troublesome and unsightly.

Le but de l'invention est de remédier à cet inconvénient en proposant une chaise repliable en tabouret dans laquelle la commodité d'emploi et la liberté esthétique ne soient pas compromises par la liaison entre le dossier et son axe d'articulation.The object of the invention is to remedy this drawback by proposing a folding chair in a stool in which the convenience of use and the aesthetic freedom are not compromised by the connection between the backrest and its axis of articulation.

Suivant l'invention, le meuble pliant comprenant un piètement, une assise et un dossier, de manière à constituer une chaise lorsqu'il est déplié, dans lequel le dossier est articulé par rapport au piètement, selon un axe sensiblement situé dans le plan de l'assise sensiblement à mi-distance entre les pieds antérieurs et postérieurs, entre la position dépliée dans laquelle le dossier s'étend en direction opposée au piètement et une position repliée dans laquelle le dossier est rabattu contre le piètement, le meuble constituant alors un tabouret, tandis qu'un élément de liaison fixé au dossier relie ce dernier à son axe d'articulation, est caractérisé en ce que l'élément de liaison est constitué par une partie au moins de l'assise.According to the invention, the folding piece of furniture comprising a base, a seat and a backrest, so as to constitute a chair when it is unfolded, in which the backrest is articulated with respect to the base, along an axis substantially situated in the plane of the seat substantially midway between the front and rear legs, between the unfolded position in which the backrest extends in the opposite direction to the base and a folded position in which the backrest is folded back against the base, the furniture then constituting a stool, while a connecting element fixed to the backrest connects the latter to its axis of articulation, is characterized in that the connecting element consists of at least part of the seat.

Ainsi, la liaison entre le dossier et son axe d'articulation est constituée par toute ou partie de l'assise, et non par un élément surajouté n'ayant aucune utilité lorsqu'on ne désire par replier ou déplier le siège.Thus, the connection between the backrest and its hinge axis is formed by all or part of the seat, and not by an added element having no use when one does not want to fold or unfold the seat.

Il est à noter que l'invention procédé de l'idée surprenante consistant à doter une partie au moins de l'assise de deux faces d'assise opposées qui sont tour à tour en fonction selon que le meuble est en position chaise ou en position tabouret.It should be noted that the invention proceeds from the surprising idea consisting in providing at least part of the seat with two opposite seat faces which are in turn depending on whether the furniture is in the chair position or in the position stool.

D'autres particularités et avantages de l'invention ressortiront encore de la description ci-après.Other features and advantages of the invention will emerge from the description below.

Dans l'exemple représenté aux figures 1 à 7, le meuble à usage de chaise ou de tabouret comprend un piètement 1 formé de quatre pieds 2 reliés rigidement entre eux, sensiblement à mi- hauteur, par un cadre 3 constitué de quatre barreaux 4.In the example shown in FIGS. 1 to 7, the piece of furniture for use as a chair or a stool comprises a base 1 formed by four feet 2 rigidly connected together, substantially at mid-height, by a frame 3 made up of four bars 4.

La meuble comprend en outre une assise 6 montée au sommet du piètement 1, et un dossier 7 comprenant deux montants 8 reliés par une traverse de base 9, une traverse d'extrémité 11 et une traverse médiane 12.The piece of furniture further comprises a seat 6 mounted at the top of the base 1, and a backrest 7 comprising two uprights 8 connected by a base cross member 9, an end cross member 11 and a middle cross member 12.

Le meuble représenté est réalisé en bois, mais d'autres matériaux, matière plastique ou métal par exemple, sont également appropriés.The furniture shown is made of wood, but other materials, plastic or metal for example, are also suitable.

Conformément à l'invention, le dossier 7 est articulé par rapport au piètement 1 selon un axe XX sensiblement parallèle à l'assise 6. Dans l'exemple représenté, l'axe XX est dans le plan de l'assise 6.According to the invention, the backrest 7 is articulated relative to the base 1 along an axis XX substantially parallel to the seat 6. In the example shown, the axis XX is in the plane of the seat 6.

Le dossier 7 est mobile autour de l'axe XX entre une position chaise -représentée aux figures 1 à 3, et une position tabouret-, représentée aux figures 5 et 6.The backrest 7 is movable around the axis XX between a chair position - shown in Figures 1 to 3, and a stool position -, shown in Figures 5 and 6.

Dans sa position chaise, le dossier 7 s'étend en direction sensiblement opposée au piètement 1 à partir du sommet des pieds postérieurs 2.In its chair position, the backrest 7 extends in a direction substantially opposite to the base 1 from the top of the rear legs 2.

Dans sa position tabouret, le dossier 7 est rabattu contre les pieds antérieurs 2 du piètement 1. Comme le montre la figure 6, le profil frontal du dossier 7 est semblable à celui du piètement 1 de sorte qu'en position tabouret, les montants 8 sont superposés aux pieds antérieurs 2, tandis que la traverse médiane 12 recouvre le barreau antérieur 4 du cadre 3. En outre les pieds antérieurs 2 et les montant 8 ont sensiblement la même longueur, de sorte que le bord libre du dossier 7, c'est-à-dire le bord longitudinal externe de la traverse 11 dans l'exemple représente, est alors très voisin du sol. Toutefois la traverse 11 ne touche pas le sol 15 si celui-ci est plan. On assure ainsi qu'au voisinage de sa position reliée, le dossier ne frotte par sur le sol, ce qui le détériorerait et l'empêcherait peut- être de se rabattre complètement contre le piètement 1 avec l'encombrement minimal.In its stool position, the backrest 7 is folded against the front feet 2 of the base 1. As shown in FIG. 6, the front profile of the backrest 7 is similar to that of the base 1 so that in the stool position, the uprights 8 are superimposed on the front legs 2, while the central crosspiece 12 covers the front bar 4 of the frame 3. In addition the front legs 2 and the uprights 8 have substantially the same length, so that the free edge of the backrest 7, it that is to say the outer longitudinal edge of the cross member 11 in the example shown, is then very close to the ground. However, the cross member 11 does not touch the ground 15 if the latter is flat. It is thus ensured that in the vicinity of its connected position, the backrest does not rub on the ground, which would deteriorate it and perhaps prevent it from folding back completely against the base 1 with the minimum bulk.

Dans l'exemple représenté aux figures 1 à 6, l'assise 6, dont les bords latéraux sont rectilignes et parallèles, est fixée rigidement au dossier 7 et montée entre deux longerons 13 qui relient deux à deux les sommets des pieds 2 de chaque côté du meuble. Outre l'assise 6, l'axe XX traverse également les longerons 13, sensiblement au milieu de l'assise 6, à mi-distance entre les pieds 2 antérieurs et postérieurs. Ainsi, c'est le montage articulé de l'assise 6 entre les longerons 13 qui permet, par retournement de l'assise à 180°, le basculement du dossier 7 entre ses deux positions extrêmes, qui sont sensiblement symétriques par rapport à l'axe XX.In the example shown in FIGS. 1 to 6, the seat 6, the lateral edges of which are rectilinear and parallel, is rigidly fixed to the backrest 7 and mounted between two side members 13 which connect the tops of the feet 2 in pairs on each side of furniture. In addition to the seat 6, the axis XX also crosses the side members 13, substantially in the middle of the seat 6, halfway between the front and rear feet 2. Thus, it is the articulated mounting of the seat 6 between the side members 13 which allows, by turning the seat 180 °, the tilting of the backrest 7 between its two extreme positions, which are substantially symmetrical with respect to the axis XX.

La base du dossier 7 est un peu plus large que l'assise 6, et, un position chaise, repose par ses deux extrémités sur deux épaulements 14 dirigés vers le haut, ménagés sur la face arrière des pieds postérieurs 2.The base of the backrest 7 is a little wider than the seat 6, and, in a chair position, rests by its two ends on two shoulders 14 directed upwards, formed on the rear face of the rear legs 2.

L'assise 6 est sensiblement parallèle au sol 15. Le siège étant déplié et vu de profil (figure 2), le plan du dossier 7 et celui des pieds antérieurs 2 sont parallèles entre eux et inclinés par rapport au sol 15 de façon à former un angle obtus A avec le sol 15 en avant du siège. Ainsi, le piètement 2 est évasé vers le bas au profit de la stabilité du meuble tandis que le dossier offre une inclinaison confortable en position dépliée tout en s'appliquant exactement contre le piètement 1 en position repliée du siège.The seat 6 is substantially parallel to the ground 15. The seat being unfolded and seen in profile (Figure 2), the plane of the backrest 7 and that of the front legs 2 are mutually parallel and inclined relative to the ground 15 so as to form an obtuse angle A with the ground 15 in front of the seat. Thus, the base 2 is flared down to the benefit of the stability of the cabinet while the backrest offers a comfortable inclination in the unfolded position while applying exactly against the base 1 in the folded position of the seat.

Comme le montre en détail la figure 7, deux broches de verrouillage 16, parallèles à l'axe XX, sont montées à coulisse dans des perçages traversant chacun l'un des longerons 13 à distance de l'axe XX, de préférence au droit des pieds postérieurs 2. Sur chacun de ses bords latéraux, l'assise 6 présente deux perçages 17 qui peuvent être occupés tour à tour par la broche 16, selon que le dossier 7 est en position chaise ou en position tabouret.As shown in detail in Figure 7, two locking pins 16, parallel to the axis XX, are slidably mounted in holes each passing through one of the side members 13 at a distance from the axis XX, preferably in line with the rear legs 2. On each of its lateral edges, the seat 6 has two holes 17 which can be occupied in turn by the spindle 16, depending on whether the backrest 7 is in the chair position or in the stool position.

Le meuble pliant ainsi constitué est mis en oeuvre comme suit:

  • En position chaise, le meuble est rigide grâce aux épaulements 14 et aux broches de verrouillage 16. Si on veut le soulever ou le déplacer en le saisissant par le dossier 7, il ne risque pas de se replier de façon imprévue, et éV.Í1!LdQDc_Jes risques de blessure.
The folding furniture thus constituted is implemented as follows:
  • In the chair position, the piece of furniture is rigid thanks to the shoulders 14 and the locking pins 16. If you want to lift it or move it by grasping it by the backrest 7, there is no risk of it folding up unexpectedly, and éV.Í1 ! LdQDc_I risk injury.

Pour faire passer le meuble en position tabouret, il suffit de retirer les broches 16 hors des perçages 17 pour les amener dans la position représentée en trait mixte à la figure 7.To move the piece of furniture into a stool position, it suffices to remove the pins 16 from the holes 17 to bring them into the position shown in dashed lines in FIG. 7.

On fait basculer le dossier 7 et l'assise 6 autour de l'axe XX jusqu'à ce que le dossier 7 soit en appui contre les pieds antérieurs 2. Il suffit ensuite de presser sur les broches 16 qui pénètrent dans les deux perçages 17 situés à l'opposé du dossier 7.The backrest 7 and the seat 6 are tilted around the axis XX until the backrest 7 is pressed against the front legs 2. It then suffices to press on the pins 16 which penetrate the two holes 17 located opposite file 7.

En position tabouret, le meuble est facile à ranger, mais aussi à utiliser car le dossier 7, qui se superpose presque exactement au piètement 1, ne constitue pas une gêne sensible.In the stool position, the furniture is easy to store, but also to use because the backrest 7, which is almost exactly superimposed on the base 1, does not constitute a significant discomfort.

Pour revenir en position chaise, il suffit de faire la manoeuvre inverse de celle décrite précédemment, la course de l'ensemble mobile étant limitée par les épaulements 14.To return to the chair position, it suffices to do the opposite maneuver to that described above, the stroke of the mobile assembly being limited by the shoulders 14.

Le mode de réalisation des figures 1 à 7 offre comme on l'a vu des avantages appréciables en ce qui concerne la commodité d'emploi et la facilité de rangement.The embodiment of FIGS. 1 to 7 offers, as we have seen, appreciable advantages as regards convenience of use and ease of storage.

Cependant, si l'on désire que l'assise soit rembourrée, elle doit l'être sur ses deux faces, celles-ci occupant tour à tour la position supérieure selon la position du meuble.However, if you want the seat to be upholstered, it must be upholstered on both sides, these occupying the upper position in turn depending on the position of the furniture.

Le mode de réalisation des figures 8 à 14 remédie à cet inconvénient. A ces figures, les éléments analogues à ceux des figures 1 à 7 sont affectés des mêmes références, et ne seront pas décrits à nouveau.The embodiment of Figures 8 to 14 overcomes this drawback. In these figures, elements similar to those of Figures 1 to 7 are given the same references, and will not be described again.

Dans ce mode de réalisation, l'assise 6a est fixée au piètement 1 tandis que les longerons 13 sont remplacés par des bras 13a fixés au dossier 7.In this embodiment, the seat 6a is fixed to the base 1 while the side members 13 are replaced by arms 13a fixed to the backrest 7.

Au-dessus de la traverse 9, qui est directement reliée aux bras 13a, le dossier 7 est légèrement rétréci de façon que son profil frontal corresponde à celui du piètement 1 en position tabouret. En effet, à encombrement égal du meuble, le piètement 1 de la presente réalisation est plus étroit que celui de la précédente, puisqu'il est situé sous l'assise 6a, et non plus sous les bras 13a.Above the cross member 9, which is directly connected to the arms 13a, the backrest 7 is slightly narrowed so that its front profile corresponds to that of the base 1 in the stool position. Indeed, with equal dimensions of the furniture, the base 1 of the present embodiment is narrower than that of the previous one, since it is located under the seat 6a, and no longer under the arms 13a.

En position chaise, le dossier 7 repose sur les épaulements 14 des pieds 2 en deux points situés juste à la base des montants 7, et non plus aux extrémités de la traverse 9.In the chair position, the backrest 7 rests on the shoulders 14 of the feet 2 at two points located just at the base of the uprights 7, and no longer at the ends of the cross-member 9.

Les bras 13a pourraient avoir toute forme ou disposition jugée appropriée pour assurer l'articulation du dossier 7 autour de l'axe XX. Dans l'exemple représenté, chaque bras 13a est adjacent à l'un des bords latéraux de l'assise 6a, et est prolongé au-delà de l'axe XX de façon à atteindre le bord de l'assise 6a opposé au dossier 7, qu'il soit en position chaise ou tabouret. Ainsi, les bras 13a n'apportent aucune gêne à l'emploi, et au contraire complètent utilement l'assise 6a. Comme le montre la figure 11, la face supérieure de l'assise fixe 6a peut avantageusement être garnie d'un rembourrage 18 qui est aussi utile en position chaise qu'en position tabouret.The arms 13a could have any shape or arrangement deemed appropriate for ensuring the articulation of the backrest 7 around the axis XX. In the example shown, each arm 13a is adjacent to one of the lateral edges of the seat 6a, and is extended beyond the axis XX so as to reach the edge of the seat 6a opposite the backrest 7, whether in the chair or stool position. Thus, the arms 13a bring no discomfort to use, and on the contrary usefully supplement the seat 6a. As shown in FIG. 11, the upper face of the fixed seat 6a can advantageously be furnished with padding 18 which is as useful in the chair position as in the stool position.

Par ailleurs, le fonctionnement et les avantages de ce mode de réalisation s'apparentent à ceux du précédent. Pour passer de la position chaise à la position tabouret, il suffit de faire basculer de 180° le dossier 7 et les bras 13a autour de l'axe XX, comme représenté en cours d'opération aux figures 8 (traits mixtes), 11 et 12. Ainsi, dans les deux positions du dossier 7, les bras 13a sont adjacents aux bords latéraux de l'assise 6a, et l'ensemble mobile peut être verrouillé grâce aux perçages 17 et aux broches 16, ces dernières étant montées chacune dans l'un des bras 13a à proximité du dossier 7.Furthermore, the operation and the advantages of this embodiment are similar to those of the previous one. To move from the chair position to the stool position, it suffices to tilt the backrest 7 and the arms 13a around 180 ° around the axis XX, as shown during operation in FIGS. 8 (dashed lines), 11 and 12. Thus, in the two positions of the backrest 7, the arms 13a are adjacent to the lateral edges of the seat 6a, and the movable assembly can be locked by virtue of the holes 17 and the pins 16, the latter being each mounted in the 'one of the arms 13a near the backrest 7.

La structure particulièrement simple conforme à l'invention offre des avantages remarquables. Bien qu'à première vue l'encombrement du meuble replié soit moins réduit que dans d'autres réalisations connues, son rangement se révèle en pratique souvent plus facile. Contrairement aux réalisations connues, le meuble est stable et rigide dans sa position repliée, peut être facilement saisi et transporté, et présente en outre une utilité en tant que tabouret.The particularly simple structure according to the invention offers remarkable advantages. Although at first glance the size of the folded piece of furniture is less reduced than in other known embodiments, its storage often turns out to be easier. Unlike the known embodiments, the piece of furniture is stable and rigid in its folded position, can be easily grasped and transported, and furthermore has utility as a stool.

Par ailleurs, le meuble conforme à l'invention permet une grande liberté esthétique.Furthermore, the furniture according to the invention allows great aesthetic freedom.

Bien entendu, l'invention n'est pas limitée aux exemples qui viennent d'être décrits, et de nombreux aménagements ou perfectionnements peuvent être apportés à ces exemples sans sortir du cadre de l'invention.Of course, the invention is not limited to the examples which have just been described, and numerous modifications or improvements can be made to these examples without departing from the scope of the invention.

En particulier, le dossier pourrait être articulé directement par sa base au piètement, de manière à être mobile entre une position chaise dans laquelle il est verrouillé par des moyens appropriés, et une position tabouret dans laquelle il est rabattu contre les pieds postérieurs.In particular, the backrest could be articulated directly by its base to the base, so as to be movable between a chair position in which it is locked by appropriate means, and a stool position in which it is folded against the hind feet.

Par ailleurs, dans la réalisation représentée, les épaulements 14 peuvent être supprimés, la maintien du dossier en position chaise étant assuré par les broches 16.Furthermore, in the embodiment shown, the shoulders 14 can be omitted, the maintenance of the backrest in the chair position being ensured by the pins 16.

Le verrouillage en position tabouret n'est pas strictement nécessaire, et les perçages 17 correspondants peuvent être supprimés si l'on désire simplifier la construction, ou encore remplacés par des billes éclipsables.Locking in the stool position is not strictly necessary, and the corresponding holes 17 can be eliminated if one wishes to simplify construction, or even replaced by eclipsable balls.

Dans les exemples représentés, l'assise 6 ou 6a est rectangulaire. Mais celle-ci peut avoir d'autres formes. Pourvu que chacun de ses bords latéraux présente une symétrie par rapport à l'axe XX, lesdits bords pourront, dans les deux positions du meuble, s'emboîter exactement entre des bras tels que 13a ou longerons tels que 13 présentant une découpe correspondante.In the examples shown, the seat 6 or 6a is rectangular. But it can have other forms. Provided that each of its lateral edges has symmetry with respect to the axis XX, said edges may, in the two positions of the cabinet, fit exactly between arms such as 13a or side members such as 13 having a corresponding cutout.
