Description

"Armature de fauteuil à repose pieds et dossier rabattables avec mémorisation de leur position d'utilisation". "Armchair frame with folding footrest and backrest with memorization of their position of use".

L'invention est relative à une armature de fauteuil du type composé d'un châssis d'assise, d'un dossier et d'un repose pieds dont les extrémités des cadres sont articulées aux extrémités du châssis, de manière à pouvoir venir en position de rangement l'un sur l'autre au dessus de l'assise, et de moyens assurant le verrouillage de chacun des cadres dans la position désirée par l'utilisateur avec possibilité de déverrouillage en fin d'utilisation. The invention relates to a chair frame of the type composed of a seat frame, a backrest and a footrest, the ends of the frames of which are articulated at the ends of the frame, so as to be able to come into position. storage one on the other above the seat, and means ensuring the locking of each of the frames in the position desired by the user with the possibility of unlocking at the end of use.

Généralement, les moyens de verrouillage sont constitués par des systèmes à crans et à cliquets procurant des positions immuables séparées par des espaces dépendant des pas des crans et dont le déverrouillage nécessite une manipulation déjà complexe pour une personne âgée. Generally, the locking means are constituted by systems with notches and ratchets providing immutable positions separated by spaces depending on the steps of the notches and the unlocking of which requires already complex manipulation for an elderly person.

Par ailleurs, la mise en position de rangement du fauteuil nécessite d'actionner les moyens de déverrouillage et oblige.ainsi l'utilisateur à effacer la position d'utilisation et donc à définir, à nouveau, cette position lors de la prochaine utilisation. Furthermore, putting the chair in the storage position requires actuation of the unlocking means and oblige.ains the user to erase the position of use and therefore to define, again, this position during the next use.

La présente invention a pour but de fournir une armature de fauteuil, de construction simple, permettant de donner à au moins l'un des cadres du dossier et du repose pieds une position quelconque entre deux valeurs extrêmes mais aussi, lors du rabattement de ce cadre sur l'assise, de n'exiger aucun actionnement des moyens de verrouillage tout en mémorisant la position d'utilisation antérieure. The object of the present invention is to provide an armchair frame, of simple construction, making it possible to give at least one of the frames of the backrest and the footrest any position between two extreme values, but also, when this frame is folded down. on the seat, to require no actuation of the locking means while memorizing the position of previous use.

A cet effet, dans cette armature du type précité, au moins l'un des cadres est muni, à proximité de son articulation sur le châssis de l'assise, d'au moins une butée apte, en position d'utilisation du cadre, à venir en contact contre une face de butée d'une bielle qui, montée libre en rotation sur le même axe que le cadre, est attelée à l'extrémité d'un moyen télescopique verrouillable en position, associé à des moyens de déverrouillage et dont l'autre extrémité est articulée sur le châssis. To this end, in this frame of the aforementioned type, at least one of the frames is provided, near its articulation on the chassis of the seat, with at least one suitable stop, in the position of use of the frame, coming into contact against a stop face of a connecting rod which, mounted free in rotation on the same axis as the frame, is coupled to the end of a telescopic means lockable in position, associated with unlocking means and of which the other end is articulated on the chassis.

Ainsi, la position angulaire du cadre est définie par celle de la bielle sur laquelle il s'appuie par sa butée. Grâce à l'indépendance du cadre par rapport à ces moyens, le cadre peut être rabattu sur l'assise sans qu'il soit nécessaire d'actionner ses moyens de calage en position d'utilisation. Ceux-ci conservent donc la position qui leur était assignée et assurent la mémorisation de cette position. Thus, the angular position of the frame is defined by that of the connecting rod on which it is supported by its stop. Thanks to the independence of the frame from these means, the frame can be folded down on the seat without it being necessary to actuate its wedging means in the position of use. They therefore keep the position assigned to them and ensure that this position is memorized.

Dans une forme d'exécution de l'invention, les moyens télescopiques sont constitués par un ressort pneumatique dont la tige est articulée sur le châssis, à proximité d'un levier pivotant d'actionnement de son dispositif de déblocage, et dont le corps est articulé sur la bielle correspondante. In one embodiment of the invention, the telescopic means consist of a pneumatic spring, the rod of which is articulated on the chassis, near a pivoting lever for actuating its release device, and the body of which is articulated on the corresponding connecting rod.

D'autres caractéristiques et avantages ressortiront de la description qui suit en référence au dessin schématique annexé représentant à titre d'exemples non limitatifs une forme d'exécution de l'invention. Other characteristics and advantages will emerge from the description which follows with reference to the appended schematic drawing showing by way of nonlimiting examples an embodiment of the invention.

Figures 1 et 2 sont des vues de côté en élévation de l'armature la représentant respectivement en position d'utilisation et en position de rangement. Figures 1 and 2 are side elevational views of the frame representing it respectively in the use position and in the storage position.

Cette armature est composée d'un châssis d'assise 1 sur lequel sont articulés, respectivement, sur les axes 2 et 3, un cadre 4 de dossier et un cadre 5 de repose pieds. Chacun des cadres 4 et 5 est muni, au niveau de son articulation et de chaque côté, d'une joue respectivement 5a et 4a. This frame is composed of a seat frame 1 on which are articulated, respectively, on the axes 2 and 3, a frame 4 of the backrest and a frame 5 of the footrest. Each of the frames 4 and 5 is provided, at its articulation and on each side, with a cheek 5a and 4a respectively.

Dans la forme d'exécution représentée, chacun des cadres 4 et 5 comporte, à proximité de son articulation, une butée respectivement 4b et 5b. Cette butée peut être constituée par une barre transversale et plate reliant les deux montants du cadre. Chaque butée est destinée à venir en appui contre une face de butée 6a ou 7a d'une bielle 6 ou 7 articulée sur le même axe 2-3 que le cadre correspondant 4 ou 5. En pratique, chaque cadre est associé à deux bielles latérales qui sont fixées sur un arbre tubulaire coaxial à l'axe 3 et montées libres en rotation sur lui. In the embodiment shown, each of the frames 4 and 5 comprises, near its articulation, a stop respectively 4b and 5b. This stop can be constituted by a transverse and flat bar connecting the two uprights of the frame. Each stop is intended to come into abutment against a stop face 6a or 7a of a connecting rod 6 or 7 articulated on the same axis 2-3 as the corresponding frame 4 or 5. In practice, each frame is associated with two lateral connecting rods which are fixed on a tubular shaft coaxial with the axis 3 and mounted free in rotation on it.

Comme le montre la figure 1, au moins l'une des bielles de chaque paire de bielles est attelée, par articulation en 8, au corps d'un ressort pneumatique 9 ou 10 dont la tige est articulée en 12 sur l'assise. As shown in FIG. 1, at least one of the connecting rods of each pair of connecting rods is coupled, by articulation at 8, to the body of an air spring 9 or 10, the rod of which is articulated at 12 on the seat.

Les tiges de commande 13 des ressorts pneumatiques qui, de façon connue, dépassent de l'extrémité de la tige 12 de ce ressort, sont disposées en vis à vis et de part et d'autre d'une palette oscillante 14 actionnable par un levier 15. The control rods 13 of the pneumatic springs which, in known manner, protrude from the end of the rod 12 of this spring, are arranged opposite and on either side of an oscillating pallet 14 actuable by a lever 15.

Ainsi un même levier commande les deux ressorts pneumatiques 9 et 10. Quand ce levier 15 est actionné, par exemple, dans le sens du déblocage du ressort 9, celui-ci est soumis à une extension dans le sens de la flèche 16 provoquant le pivotement des bielles 10 et le redressement du dossier 4 dans le sens de la flèche 17 jusqu'à obtention de la position désirée. Pour déplacer le dossier en sens inverse, il faut exercer sur lui un effort physique en actionnant le levier 15 pour débloquer le ressort pneumatique 9 et permettre sa contraction. Thus the same lever controls the two pneumatic springs 9 and 10. When this lever 15 is actuated, for example, in the direction of release of the spring 9, the latter is subjected to an extension in the direction of the arrow 16 causing the pivoting connecting rods 10 and straightening the backrest 4 in the direction of arrow 17 until the desired position is obtained. To move the backrest in the opposite direction, physical effort must be exerted on it by actuating the lever 15 to release the air spring 9 and allow it to contract.

I1 est évident que la même opération peut être effectuée sur le repose pieds. It is obvious that the same operation can be carried out on the footrest.

Avec l'agencement, selon l'invention, lorsque l'utilisateur a trouvé une position particulièrement adaptée, il lui est possible de ranger le fauteuil de relaxation sans avoir à perdre cette position, ce qui exigerait qu'il la retrouve lors de la manipulation suivante. With the arrangement according to the invention, when the user has found a particularly suitable position, it is possible for him to store the relaxation chair without having to lose this position, which would require him to find it during handling. next.

Pour cela, il lui suffit, comme le montre la figure 2 de rabattre le repose pieds 5 et le dossier 4 sur l'assise. Ce rabattement éloigne les butées des cadres 4 et 5 des bielles respectives sans modifier la position de ces bielles, qui assurent ainsi la mémorisation de la position idéale retenue par l'utilisateur. Dans une variante de réalisation, et pour éviter le rabattement intempestif de l'un des cadres sur le dossier, par exemple par l'appui d'une personne sur l'extrémité de celui-ci, une cheville amovible transversale 20 est engagée dans des perforations appropriées de la bielle 6-7 et de la joue 4a-5a correspondante. For this, it suffices, as shown in Figure 2 to fold the footrest 5 and the backrest 4 on the seat. This folding away from the stops of the frames 4 and 5 of the respective connecting rods without changing the position of these connecting rods, which thus ensure the storage of the ideal position retained by the user. In an alternative embodiment, and to avoid inadvertent folding down of one of the frames on the backrest, for example by the support of a person on the end of the latter, a removable transverse pin 20 is engaged in appropriate perforations of the rod 6-7 and the corresponding cheek 4a-5a.
