Definitions
- the present invention relates to an indoor or outdoor armchair which comprises, on the one hand, a seat supported by two lateral pairs of legs extending above the seat to receive armrests and, on the other hand , a backrest articulated at its base relative to the rear of this seat, as well as above relative to the armrests.
- the invention aims to allow the back of the chair to fold forward to cover the seat and therefore make the chair stackable. Concomitantly, for the maneuver to be simple, quick and easy, the armrests must follow the backrest when it is folded down without it being necessary to dismantle parts which may be accompanied by losses.
- the invention also aims to ensure that the backrest is adjustable in inclination without the above-mentioned essential aim being compromised.
- the invention finally aims to ensure that the chair can be made of plastic with a very small number of components, therefore of molds, and can be easily and quickly mounted without particular skill with a very small number of connecting axes.
- the invention resides in that the legs of each pair converge upwards and are rigidly connected by a high cross member in order to be stackable and in that each armrest resting on the conjugate cross member is fixed on it. ci in a removable way and connected to the backrest by a hinge pin located above the level of the armrest considered at a distance from the hinge pin of the backrest on the seat such, relative to the distance of this second axis at the anterior end of the above-mentioned conjugate cross-member, that the rear end of the armrest in question can cross the front end of said cross-member, during the folding of the backrest on the seat.
- each armrest contains a rack cooperating with a finger of the conjugate crosspiece, finger which is trapped in the armrest over the entire adjustment stroke thanks to which the backrest is adjustable in inclination, this armrest having a lower opening located at the rear of the rack so that the finger can escape when said armrest is raised to fold the backrest.
- the seat is made monolithic, preferably by molding, with the two pairs of legs.
- Each armrest is extended, for its articulation on the backrest, by a raised stick located on the inner side of the conjugate crossing, this stick coming to be placed during the folding of the backrest in a previous recess of the seat and coming to abut against the bottom of this recess to determine the substantially horizontal folded position of the corresponding armrest.
- the four components of the armchair consisting of the seat and its legs, the backrest and the two armrests, are made of molded plastic.
- the armchair is made of molded plastic and manufactured in four pieces consisting of a stool 1, a backrest 2, a right armrest 3 and a left armrest 4.
- the stool 1 has a seat 5 molded with four legs 6 to 9 and extending at an intermediate level relative thereto.
- the legs 6 and 7 located on the right side converge upward and are interconnected at their upper part by a high cross member 10; similarly, the legs 8 and 9 located on the left side converge upwards and are connected to each other at their upper part by a high cross member 11.
- the stools 1 of several armchairs are stackable, provided however that the backrests 2 and the armrests 3, 4 can be folded forward against the corresponding seats 5.
- the backrest 2 of the chair shown in Figures 1 and 2 is articulated at its base relative to the rear of the seat 5 by means of axes 12, 13 passing through legs 14 and 15, 16 and 17 coming molding with said back and said seat.
- the right armrest 3 fitting onto the upper crossmember 10 of the stool in a removable manner is articulated on the backrest 2 by means of an axis 18 passing through a butt-shaped extension 19 of said armrest and likewise, the left armrest 4 fitting onto the upper crossmember 11 of the stool in a removable manner, is articulated on the backrest 2 by means of an axis 20 passing through a butt-shaped extension 21 of said armrest.
- the axes 18 and 20 are aligned parallel to the axes 12 and 13 which are themselves aligned; in addition, the brackets 19 and 21 make it possible to define the position of the axes 18 and 20 high enough above the level of the armrests. This arrangement allows, as described in detail in this which follows for the left side with reference to FIG. 2, folding the backrest 2 onto the seat 5 and successfully crossing the high crosspieces 10, 11 with the armrests, the sticks remaining on the inside.
- the backrest 2 is foldable, but it can also be adjustable in inclination.
- each of the armrests 3 and 4 has an internal rack cooperating selectively with a finger of the high cross member. These means are illustrated for the left armrest 4 in FIGS. 4 and 5.
- a rising leg 22 has come from molding with the high cross member 11 of the stool and ends with a finger 23 projecting from both sides.
- the armrest 4 is U-shaped and covers the tab 22 and its finger 23; its top 24 has ribs 25 projecting internally to form a rack cooperating with finger 23; depending on the selected rib, the armrest is more or less advanced and the backrest is more or less inclined; in addition, the side walls of the armrest have internally projecting lower flanges 25 which prevent the finger 23 from escaping; however, sufficient clearance is provided between the ribs 25 and the flanges 26 in order to be able to lift the armrest and move it in translation when the backrest changes inclination. Furthermore, the edges 26 are interrupted at the rear of the armrest, in order to delimit an opening 27 allowing the armrest 4 to be completely released from the finger 23, by pivoting upwards.
- the distance "R” separating the articulation axes 13 (and 12) of the backrest 2 on the seat 5 and the articulation axes 20 (and 18) of the backrest 2 on the armrests 4 (and 3) is such with respect to the distance "d” separating these axes 13 (and 12) of the front ends 28 of the high crosspieces 11 (and 10) of the stool to each position of the backrest 2 (position 2.1 for example) a raised position (4.2) of the armrests 4 (and 3) in which the spacing "E” between the axes 13 (and 12) and the rear ends 29 of said armrests is equal to said distance "d".
- the crossing of the crosspieces by the armrests during the folding of the backrest becomes possible thanks to the crosspieces 21 (and 19) which move the axes 20 (and 18) away from the axes 13 (and 12).
- the backrest 2 comes to rest on the seat 5 (position 2.3) and the brackets 21 (and 19) are placed in recesses 31 (and 30) of the seat ( Figure 1).
- the substantially horizontal lower position 4.3 of the armrests is obtained by abutment of their hooks against the bottom 32 of the abovementioned recesses.

According to the invention, the legs (8 and 9) of each pair converge upwards and are rigidly connected by a high crosspiece (11) so as to be stackable; in addition, each armrest (4) resting on the conjugate crossmember (11) is fixed thereon in a removable manner and connected to the backrest (2) by a hinge pin (20) located above the level of the armrest considered at a distance "R" from the articulation axis (13) of the backrest (2) on the seat (5) as, relative to the distance (d ") of this second axis at the anterior end ( 28) of the aforementioned conjugate cross, that the rear end (29) of the armrest considered can cross the front end (28) of said cross during the folding of the backrest on the seat.
Description
La présente invention concerne un fauteuil d'intérieur ou d'extérieur qui comprend, d'une part, une assise supportée par deux paires latérales de jambages s'étendant au-dessus de l'assise pour recevoir des accoudoirs et, d'autre part, un dossier articulé à sa base relativement à l'arrière de cette assise, ainsi qu'au dessus relativement aux accoudoirs.The present invention relates to an indoor or outdoor armchair which comprises, on the one hand, a seat supported by two lateral pairs of legs extending above the seat to receive armrests and, on the other hand , a backrest articulated at its base relative to the rear of this seat, as well as above relative to the armrests.
L'invention a pour but de permettre au dossier du fauteuil de se plier vers l'avant pour recouvrir l'assise et par conséquent de rendre ce fauteuil empilable. Concomitamment, pour que la manoeuvre soit simple, rapide et aisée, les accoudoirs doivent suivre le dossier lors de son repliement sans qu'il soit nécessaire de procéder à des démontages de pièces pouvant s'accompagner de pertes.The invention aims to allow the back of the chair to fold forward to cover the seat and therefore make the chair stackable. Concomitantly, for the maneuver to be simple, quick and easy, the armrests must follow the backrest when it is folded down without it being necessary to dismantle parts which may be accompanied by losses.
L'invention vise également à ce que le dossier soit règlable en inclinaison sans que le but essentiel précité soit compromis.The invention also aims to ensure that the backrest is adjustable in inclination without the above-mentioned essential aim being compromised.
L'invention vise enfin à ce que le fauteuil puisse être fabriqué en matière plastique avec un nombre très réduit de composants, donc de moules, et puisse être monté facilement et rapidement sans compétence partculière avec un nombre très faible d'axes de liaison.The invention finally aims to ensure that the chair can be made of plastic with a very small number of components, therefore of molds, and can be easily and quickly mounted without particular skill with a very small number of connecting axes.
Pour atteindre ce but, l'invention réside en ce que les jambages de chaque paire convergent vers le haut et sont reliés rigidement par une traverse haute afin d'être empilables et en ce que chaque accoudoir reposant sur la traverse conjuguée est fixé sur celle-ci de façon démontable et relié au dossier par un axe d'articulation situé au-dessus du niveau de l'accoudoir considéré à une distance de l'axe d'articulation du dossier sur l'assise telle, relativement à la distance de ce deuxième axe à l'extrémité antérieure de la traverse conjuguée précitée, que l'extrémité postérieure de l'accoudoir considéré puisse franchir l'extrémité antérieure de ladite traverse, pendant le repliement du dossier sur l'assise.To achieve this object, the invention resides in that the legs of each pair converge upwards and are rigidly connected by a high cross member in order to be stackable and in that each armrest resting on the conjugate cross member is fixed on it. ci in a removable way and connected to the backrest by a hinge pin located above the level of the armrest considered at a distance from the hinge pin of the backrest on the seat such, relative to the distance of this second axis at the anterior end of the above-mentioned conjugate cross-member, that the rear end of the armrest in question can cross the front end of said cross-member, during the folding of the backrest on the seat.
Par ailleurs, et conformément l'invention, chaque accoudoir contient une crémaillère coopérant avec un doigt de la traverse conjuguée, doigt qui est prisonnier de l'accoudoir sur toute la course de règlage grâce à laquelle le dossier est règlable en inclinaison, cet accoudoir présentant une ouverture inférieure située à l'arrière de la crémaillère afin que le doigt puisse échapper lorsque ledit accoudoir est relevé pour replier le dossier.Furthermore, and in accordance with the invention, each armrest contains a rack cooperating with a finger of the conjugate crosspiece, finger which is trapped in the armrest over the entire adjustment stroke thanks to which the backrest is adjustable in inclination, this armrest having a lower opening located at the rear of the rack so that the finger can escape when said armrest is raised to fold the backrest.
Suivant d'autres caractéristiques importantes de l'invention, l'assise est rendue monolithique, de préférence par moulage, avec les deux paires de jambages.According to other important features of the invention, the seat is made monolithic, preferably by molding, with the two pairs of legs.
Chaque accoudoir est prolongé, pour son articulation sur le dossier, par une crosse relevée située du côté intérieur de la traversée conjuguée, cette crosse venant se placer lors du repliement du dossier dans un décrochement antérieur de l'assise et venant buter contre le fond de ce décrochement pour déterminer la position sensiblement horizontale de repliement de l'accoudoir correspondant.Each armrest is extended, for its articulation on the backrest, by a raised stick located on the inner side of the conjugate crossing, this stick coming to be placed during the folding of the backrest in a previous recess of the seat and coming to abut against the bottom of this recess to determine the substantially horizontal folded position of the corresponding armrest.
Les quatre composants du fauteuil, constitués par l'assise et ses jambages, le dossier et les deux accoudoirs, sont en matière plastique moulée.The four components of the armchair, consisting of the seat and its legs, the backrest and the two armrests, are made of molded plastic.
Divers autres caractéristiques et avantages de l'invention ressortent d'ailleurs de la description détaillée qui suit.Various other characteristics and advantages of the invention will also emerge from the detailed description which follows.
Une forme de réalisation de l'objet de l'invention est représentée, à titre d'exemple non limitatif, sur le dessin annexé.An embodiment of the object of the invention is shown, by way of nonlimiting example, in the accompanying drawing.
Sur ce dessin :
- - la figure 1 est une perspective du fauteuil conforme à l'invention,
- - la figure 2 est une élévation latérale illustrant l'inclinaison du dossier et son repliement sur l'assise accompagné du coulissement, du soulèvement et du rabattement des accoudoirs,
- - la figure 3 est une vue analogue à la figure 2 montrant l'empilage des fauteuils,
- - la figure 4 est une coupe prise, à plus grande échelle, suivant la ligne IV-IV de la figure 1, pour visualiser la crémaillère d'inclinaison du dossier.
- - la figure 5 est une coupe prise suivant la ligne V-V de la figure 4.
- FIG. 1 is a perspective of the chair according to the invention,
- FIG. 2 is a side elevation illustrating the inclination of the backrest and its folding back onto the seat accompanied by the sliding, lifting and folding of the armrests,
- FIG. 3 is a view similar to FIG. 2 showing the stacking of the chairs,
- FIG. 4 is a section taken, on a larger scale, along line IV-IV of Figure 1, to view the backrest tilt rack.
- - Figure 5 is a section taken on the line VV in Figure 4.
Dans cette forme de réalisation, le fauteuil est réalisé en matière plastique moulée et fabriqué en quatre morceaux constitués par un tabouret 1, un dossier 2, un accoudoir droit 3 et un accoudoir gauche 4.In this embodiment, the armchair is made of molded plastic and manufactured in four pieces consisting of a
Le tabouret 1 comporte une assise 5 venue de moulage avec quatre jambages 6 à 9 et s'étendant à un niveau intermédiaire relativement à ceux-ci. Les jambages 6 et 7 situés du côté droit convergent vers le haut et sont reliés entre eux à leur partie supérieure par une traverse haute 10 ; de même, les jambages 8 et 9 situés du côté gauche convergent vers le haut et sont reliés entre eux à leur partie supérieure par une traverse haute 11.The
Dès lors, les tabourets 1 de plusieurs fauteuils sont empilables, à condition cependant que les dossiers 2 et les accoudoirs 3, 4 puissent être repliés vers l'avant contre les assises 5 correspondantes.Consequently, the
A cet effet, le dossier 2 du fauteuil représenté sur les figures 1 et 2 est articulé à sa base relativement à l'arrière de l'assise 5 au moyen d'axes 12, 13 traversant des pattes 14 et 15, 16 et 17 venues de moulage avec ledit dossier et ladite assise. Par ailleurs, l'accoudoir droit 3 s'emboîtant sur la traverse haute 10 du tabouret de façon démontable est articulé sur le dossier 2 au moyen d'un axe 18 traversant un prolongement en forme de crosse 19 dudit accoudoir et de même, l'accoudoir gauche 4 s'emboîtant sur la traverse haute 11 du tabouret de façon démontable, est articulé sur le dossier 2 au moyen d'un axe 20 traversant un prolongement en forme de crosse 21 dudit accoudoir. Les axes 18 et 20 sont alignés parallèlement aux axes 12 et 13 qui sont eux-mêmes alignés ; de plus, les crosses 19 et 21 permettent de définir la position des axes 18 et 20 suffisamment haut au-dessus du niveau des accoudoirs. Cette disposition permet, ainsi que cela est décrit en détail dans ce qui suit pour le côté gauche en se référant à la figure 2, de replier le dossier 2 sur l'assise 5 et de réussir le franchissement des traverses hautes 10, 11 par les accoudoirs, les crosses restant sur le côté intérieur.To this end, the
Le dossier 2 est repliable, mais il peut aussi être règlabe en inclinaison.The
A cet effet, chacun des accoudoirs 3 et 4 comporte une crémaillère interne coopérant sélectivement avec un doigt de la traverse haute conjuguée. Ces moyens sont illustrés pour l'accoudoir gauche 4 sur les figures 4 et 5. Une patte montante 22 est venue de moulage avec la traverse haute 11 du tabouret et se termine par un doigt 23 faisant saillie des deux côtés. L'accoudoir 4 est profilé en U et coiffe la patte 22 et son doigt 23 ; son dessus 24 présente en saillie interne des nervures 25 afin de former une crémaillère coopérant avec le doigt 23 ; suivant la nervure sélectionnée, l'accoudoir est plus ou moins avancé et le dossier est plus ou mons incliné ; de plus, les parois latérales de l'accoudoir présentent en saillie interne des rebords inférieurs 25 qui empêchent le doigt 23 d'échapper ; cependant, un jeu suffisant est ménagé entre les nervures 25 et les rebords 26 afin de pouvoir soulever l'accoudoir et le déplacer en translation lors d'un changement d'inclinaison du dossier. Par ailleurs, les rebords 26 sont interrompus à l'arrière de l'accoudoir, afin de délimiter une ouverture 27 permettant de dégager complètement l'accoudoir 4 du doigt 23, par pivotement vers le haut.To this end, each of the
Il est très important de remarquer, avant de décrire le repliement du fauteuil pour son empilage (figures 2 et 5) que les crosses 21 (et 19) s'étendent du côté intérieur des traverses 10 (et 11) du tabouret, mais que par contre, les accoudoirs 4 (et 3) sont toujours situés à l'aplomb de ces traverses jusqu'à leur extrémité postérieure 29. D'autre part, la distance "R" séparant les axes d'articulation 13 (et 12) du dossier 2 sur l'assise 5 et les axes d'articulation 20 (et 18) du dossier 2 sur les accoudoirs 4 (et 3) est telle par rapport à la distance "d" séparant ces axes 13 (et 12) des extrémités antérieures 28 des traverses hautes 11 (et 10) du tabouret qu'à chaque position du dossier 2 (position 2.1 par exemple) correspond une position relevée (4.2) des accoudoirs 4 (et 3) dans laquelle l'écartement "E" entre les axes 13 (et 12) et les extrémités postérieures 29 desdits accoudoirs est égal à ladite distance "d". Autrement dit, le franchissement des traverses par les accoudoirs lors du repliement du dossier devient possible grâce aux crosses 21 (et 19) qui éloignent les axes 20 (et 18) des axes 13 (et 12).It is very important to note, before describing the folding of the chair for its stacking (Figures 2 and 5) that the hooks 21 (and 19) extend from the inside of the crosspieces 10 (and 11) of the stool, but only by against, the armrests 4 (and 3) are always located plumb with these crosspieces up to their
Pour replier le fauteuil, il faut procéder comme cela ressort de la figure 2 :
- tout d'abord, il faut déplacer les accoudoirs 4 (et 3) en translation dans le sens de la flèche F.1 jusqu'à ce qu'ils occupent la postion antérieure 4.1 dans laquelle leur ouverture 27 est située en regard des doigts 23 ; ;aga cette position 4.1 des accoudoirs, correspond la position antérieure 2.1 du dossier,
- puis, il faut relever lesdits accoudoirs en les faisant pivoter vers le haut dans le sens de la flèche F.2 autour des axes 20 (et 18) et en même temps, il faut faire pivoter le dossier 2 vers l'avant dans le sens de la flèche F.3 autour des axes 13 (et 12),
- ensuite, après avoir fait reposer les extrémités postérieures 29 des accoudoirs 4 (et 3) sur les traverses hautes 11 (et 10) du tabouret, il faut poursuivre le pivotement du dossier 2 dans le sens de la flèche F.3,
- lors du franchissement des extrémités antérieures 28 des traverses par les extrémités postérieures 29 des accoudoirs, il faut retenir ceux-ci. Le dossier 2 vient s'appuyer sur l'assise 5 (position 2.3) et les crosses 21 (et 19) viennent se placer dans des décrochements 31 (et 30) de l'assise (figure 1). La position basse 4.3 sensiblement horizontale des accoudoirs est obtenue par butée de leurs crosses contre le fond 32 des décrochements précités.To fold the chair, proceed as shown in Figure 2:
- first of all, the armrests 4 (and 3) must be moved in translation in the direction of the arrow F.1 until they occupy the anterior position 4.1 in which their
- Then, it is necessary to raise said armrests by rotating them upwards in the direction of arrow F.2 around the axes 20 (and 18) and at the same time, it is necessary to rotate the
- then, after having rested the
- When crossing the front ends 28 of the crosspieces by the
Comme le montre la figure 3, dans cette position 4.3 des accoudoirs de plusieurs fauteuils empilés, il subsiste entre les extrémités postérieures 29 desdits accoudoirs et les jambages antérieurs 6, 8 des passages 33 à travers lesquels les jambages homologues 6, 8 d'au moins un nouveau fauteuil à empiler peuvent être introduits en étant guidés à l'intérieur par les crosses 21 (et 19) des fauteuils sous-jacents.As shown in Figure 3, in this position 4.3 of the armrests of several stacked armchairs, there remains between the
Bien entendu, le fauteuil peut être constitué par d'autres matériaux et assemblé différemment. Par exemple, chaque paire de jambages peut être en tube métallique cintré fixé au moyen de vis sur une assise en bois ; le dossier peut être un cadre en bois rempli d'un garnissage confortable comme cela peut également être le cas pour l'assise ; les accoudoirs peuvent être en bois avec une crémaillère et une ferrure d'articulation métalliques. Mais il est bien évident que la construction choisie et représentée en matière plastique est préférable pour des raisons d'esthétique, d'entretien, de prix de revient...Of course, the chair can be made of other materials and assembled differently. For example, each pair of legs can be made of bent metal tube fixed by means of screws on a wooden seat; the backrest can be a wooden frame filled with comfortable padding, as can also be the case for the seat; the armrests can be made of wood with a metal rack and hinge fitting. But it is obvious that the construction chosen and represented in plastic material is preferable for reasons of aesthetics, maintenance, cost price ...
