Abstract

A period chair, entirely motor-operated which the user can transform into a chair for resting of relaxation or into a bed, without leaving the chair or without the aid of another person for placing in position the foot support.

Description

La présente invention concerne des sièges conçus pour être transformables par leur utilisateur en siège de repos ou en siège de relaxation ou en lit. De nombreux modèles de sièges ou de fauteuils transformables sont déjà connus. Leur actionnement est le plus souvent réalisé par l'utilisateur qui, par ses propres efforts, modifie l'équilibre du siège, ou qui actionne un ou plusieurs leviers.. Ils sont rarement motorisés et cette motorisation est toujours partielle.The present invention relates to seats designed to be transformable by their user into a rest seat or a relaxation seat or a bed. Many models of transformable seats or armchairs are already known. Their actuation is most often carried out by the user who, by his own efforts, modifies the balance of the seat, or who actuates one or more levers. They are rarely motorized and this motorization is always partial.

Les modèles connus de fauteuils dits de repos ou de détente présentent un repose-pieds qui ne soutient que très partiellement les jambes (US-A-3 588 170 ou US-A-1 442 338). Le brevet US-A-1 442 338 sert de base au préambule de la revendication 1. Les modèles connus de fauteuils dits de relaxation ne peuvent faire disparaître le repose-pieds, du fait de sa nécessaire grande longueur, sans l'aide d'une personne extérieure, ou par l'utilisateur qui doit sortir de son siège, et dans l'obligation de trouver un endroit de rangement pour le coussin de repose-pieds. Quelques rares modèles connus ne présentent pas cet inconvénient, mais leur esthétique, par leur assise trop haute, est très médiocre (US-A 4 691 694, US-A-3 907 051, FR-2 309 178).The known models of so-called rest or relaxation armchairs have a footrest which only partially supports the legs (US-A-3,588,170 or US-A-1,442,338). US-A-1 442 338 serves as a basis for the preamble of claim 1. Known models of so-called relaxation chairs cannot remove the footrest, because of its necessary great length, without the aid of an outside person, or by the user who must get out of his seat, and in the obligation to find a storage place for the footrest cushion. Some rare known models do not have this drawback, but their aesthetics, by their too high seat, is very poor (US-A 4,691,694, US-A-3,907,051, FR-2,309,178).

La nouveauté de la présente invention réside, d'une part dans la réunion dans un même siège d'avantages que l'on trouve répartis dans différents modèles connus, et réputés incompatibles entre eux, et d'autre part des avantages qui lui sont propres, principalement de pouvoir être qualifié par un public averti de "griffé" ou de "style" et d'offrir en même temps à son utilisateur la possibilité de le transformer en siège de relaxation, ou en fauteuil de repos ou de détente, à son choix, sans efforts de sa part, et sans problème de rangement du repose-pieds, qui est néanmoins fonctionnel et confortable par sa grande longueur. Ce siège est donc caractérisé par une esthétique, une fonctionalité et une simplicité d'utilisation inconnues aujourd'hui l'utilisateur pouvant atteindre n'importe quelle position sans quitter son siège.The novelty of the present invention resides, on the one hand in the combination in a same seat of advantages which are found distributed in different known models, and deemed to be incompatible with each other, and on the other hand of the advantages which are specific to it. , mainly to be able to be qualified by an informed public of "scratched" or "style" and to offer at the same time to its user the possibility of transforming it into a relaxation seat, or into a rest or relaxation chair, at its choice, without effort on its part, and without problem of storage of the footrest, which is nevertheless functional and comfortable by its great length. This seat is therefore characterized by an aesthetics, a functionality and a simplicity of use unknown today the user being able to reach any position without leaving his seat.

Le siège représenté en figure 1 est à titre d'exemple un fauteuil, mais on pourrait envisager une bergère ou même un canapé ou tout autre siège selon le style que l'on recherche, ici d'époque classique,mais d'autres époques pourraient être envisagées, ou l'usage que l'on désire en faire, ici un meuble de salon, mais on peut envisager des meubles plus sobres pour l'extérieur, ou adaptés à des fins professionnelles médicales, paramédicales ou autres, ou spécialement adaptés à des personnes handicapées ou agées.The seat shown in FIG. 1 is by way of example an armchair, but one could envisage a shepherdess or even a sofa or any other seat depending on the style that one is looking for, here of classical era, but other eras could be considered, or the use that one wishes to make of it, here a living room furniture, but one can consider more sober furniture for the outside, or adapted for professional medical, paramedical or other purposes, or specially adapted to disabled or elderly people.

Ce siège est constitué d'un piètement 1, d'un coussin d'assise 2, des accoudoirs 3, d'un dossier 4 et son coussin 5 . Sous le coussin d'assise est dissimulé un ensemble mécanique 6 et un repose-pieds qui ne sont pas visibles. L'esthétique du siège en position "salon", tel qu'il est présenté ici, est alors totalement intacte. En se reportant à la figure 2, le mécanisme est supporté par le piètement 1 ou caisse ou carcasse, selon le style ou la destination du siège. Il se compose d'un chassis fixe 10 supportant un chassis mobile 11 qui porte le coussin d'assise 2, par l'intermédiaire de quatre biellettes 12 et 13. Il faut noter que dans les vues où le mécanisme est représenté de profil, on ne voit que les biellettes situées sur un côté, le mécanisme étant symétrique. Ces biellettes sont particulièrement articulées les unes, 12, par les axes 14 situés sous le niveau du chassis mobile 11, les autres, 13, par les axes 15 situés au-dessus du chassis mobile 11.This seat consists of a base 1, a seat cushion 2, the armrests 3, a backrest 4 and its cushion 5. Under the seat cushion is concealed a mechanical assembly 6 and a footrest which are not visible. The aesthetics of the seat in the "lounge" position, as it is presented here, is then completely intact. Referring to Figure 2, the mechanism is supported by the base 1 or body or carcass, depending on the style or destination of the seat. It consists of a fixed frame 10 supporting a movable frame 11 which carries the seat cushion 2, by means of four links 12 and 13. It should be noted that in the views where the mechanism is shown in profile, we sees only the rods located on one side, the mechanism being symmetrical. These links are particularly articulated, one, 12, by the axes 14 located below the level of the movable chassis 11, the other, 13, by the axes 15 situated above the movable chassis 11.

Cette disposition propre à l'invention permet d'une manière simple une variation continue de l'inclinaison, nulle au départ, jusqu'à une valeur maximale sans modification importante de la position du centre de gravité de l'utilisateur ce qui est un avantage de confort. Un autre avantage de cette géométrie, est de soulever l'extrémité de l'assise et de permettre le déploiement du repose-pieds. Un autre avantage est de pouvoir par dépassement de l'inclinaison maximale, retrouver une valeur nulle avec un déplacement notable cette fois de l'assise et du centre de gravité de l'utilisateur pour obtenir une position chaise longue ou lit, sans crainte de basculement du siège donc sans la nécessité d'un piètement supplémentaire.This arrangement specific to the invention allows in a simple manner a continuous variation of the inclination, zero at the start, up to a maximum value without significant modification of the position of the user's center of gravity which is an advantage comfort. Another advantage of this geometry is to raise the end of the seat and allow the deployment of the footrest. Another advantage is to be able by exceeding the maximum inclination, finding a zero value with a notable displacement this time of the seat and the center of gravity of the user to obtain a position chaise longue or bed, without fear of tilting seat therefore without the need for an additional base.

L'inclinaison est obtenue par un actionneur à translation 16, électrique, hydraulique, pneumatique ou mû par toute autre forme d'énergie selon l'utilisation, appuyé en 17 sur le chassis fixe et en 18 sur le chassis mobile. Pour des raisons de sécurité, cet actionneur est autobloquant c'est-à-dire qu'en l'absence de commande, l'actionneur ne peut changer de position.sous l'action d'une force extérieure. Dans l'exemple décrit, l'actionneur a une position centrale, mais on pourrait envisager de le remplacer par deux actionneurs disposés latéralement. Sur le chassis mobile s'articule le support de dossier portant le dossier 4 et son coussin 5 dont l'inclinaison est obtenue par un actionneur 20 semblable à l'actionneur 16 qui peut aussi être remplacé par deux actionneurs latéraux. Le dossier 4 est articulé sur son support en 21 ce qui permet de le transporter plié. Un verrouillage 22 le maintient pendant l'utilisation.The inclination is obtained by a translational actuator 16, electric, hydraulic, pneumatic or driven by any other form of energy depending on the use, supported at 17 on the fixed chassis and at 18 on the mobile chassis. For safety reasons, this actuator is self-locking, i.e. in the absence of a command, the actuator cannot change position under the action of an external force. In the example described, the actuator has a central position, but it could be envisaged to replace it with two actuators arranged laterally. On the movable frame is articulated the backrest support carrying the backrest 4 and its cushion 5 whose inclination is obtained by an actuator 20 similar to the actuator 16 which can also be replaced by two lateral actuators. The file 4 is articulated on its support at 21 which allows it to be transported folded. A lock 22 maintains it during use.

En se reportant à la figure 3 , le chassis mobile 11 supporte le repose-pieds 23 et son coussin 24, qui peuvent être invisibles en se repliant sous l'assise. La traverse de décor 25 est portée par le repose-pieds 23, l'ensemble étant relié au chassis mobile par quatre biellettes 26 et 27 dont la forme particulière permet un débordement latéral du coussin d'assise et de la traverse de décor, parachevant ainsi l'esthétique du siège et dissimulant complètement le repose-pieds et la mécanique en position "salon".Referring to Figure 3, the movable frame 11 supports the footrest 23 and its cushion 24, which can be invisible by folding under the seat. The decorative crosspiece 25 is carried by the footrest 23, the assembly being connected to the movable chassis by four links 26 and 27 whose particular shape allows a lateral overflow of the seat cushion and the decorative crosspiece, thus completing the aesthetics of the seat and completely concealing the footrest and the mechanics in the "lounge" position.

La biellette 26 est articulée en 28 sur le chassis mobile 11, et en 29 sur le repose-pieds 23. Elle est articulée en 30 avec un actionneur 31, semblable à l'actionneur 16, articulé en 32 au chassis mobile. La biellette 27 est articulée en 33 sur le chassis mobile, en dessous de l'articulation 28 et en 34 sur le repose-pieds en dessous et en avant de l'articulation 29 en position repliée. Cette géométrie particulière où les biellettes se croisent a l'avantage de permettre un développement du repose-pieds dans un passage de hauteur plus faible qu'avec une simple articulation qui de surcroît aurait été visible.The link 26 is articulated at 28 on the movable chassis 11, and at 29 on the footrest 23. It is articulated at 30 with an actuator 31, similar to the actuator 16, articulated at 32 to the movable chassis. The link 27 is articulated at 33 on the movable chassis, below the articulation 28 and at 34 on the footrest below and in front of the articulation 29 in the folded position. This particular geometry where the links cross has the advantage of allowing the development of the footrest in a passage of lower height than with a simple articulation which in addition would have been visible.

La figure 4 montre une variante de l'invention lorsque l'on veut aider l' utilisateur à se relever ou à s'asseoir. Un chassis 40 supportant le coussin d'assise 2 et le support de dossier 19 est supporté par le chassis mobile 11 par l'intermédiaire de quatre biellettes 41 et 42. La biellette 41 est articulée en 43 sur le chassis 40, et en 44 sur le chassis mobile 11. La biellette 42 est articulée en 45 sur le chassis 40, et en 46 sur le chassis mobile 11. Par sa disposition particulière, le chassis 40 se trouve soulevé dès que le dossier est complètement relevé alors que l'actionneur 20 continue à se déployer.Figure 4 shows a variant of the invention when one wants to help the user to get up or sit down. A chassis 40 supporting the seat cushion 2 and the backrest support 19 is supported by the movable chassis 11 by means of four links 41 and 42. The link 41 is articulated at 43 on the chassis 40, and at 44 on the mobile chassis 11. The link 42 is articulated at 45 on the chassis 40, and at 46 on the mobile chassis 11. By its particular arrangement, the chassis 40 is raised as soon as that the backrest is completely raised while the actuator 20 continues to deploy.

La figure 5 montre une variante du repose-pieds qui en deux parties 34 et 35 permet son déploiement dans une hauteur encore plus faible grâce à une came 36 solidaire de la biellette motrice 26 et de deux biellettes 37 munies de deux galets 38 et 39 qui roulent sur la came 36.Figure 5 shows a variant of the footrest which in two parts 34 and 35 allows its deployment in an even lower height thanks to a cam 36 secured to the drive rod 26 and two rods 37 provided with two rollers 38 and 39 which roll on cam 36.

Les actionneurs sont commandés par des boutons 47 et 48 en nombre suffisant , dissimulés pour sauvegarder l'esthétique dans le ou les accoudoirs, ce qui est un avantage par rapport aux commandes "à bout de fil" que l'on connaît (US-A 4 691 964) qui peuvent tomber hors d'atteinte de l'utilisateur assis dans le siège, disparaître entre les coussins quand l'utilisateur n'est pas lui-même assis dessus. Ces commandes ne sont pas sur l'accoudoir (US-A 3 907 051), ce que l'on connaît, mais dessous sur la face 59, ou derrière sur la face 60, ainsi que le montrent les figures 6 et 7.The actuators are controlled by buttons 47 and 48 in sufficient number, concealed to save the aesthetics in the armrest (s), which is an advantage compared to the "wired" controls that we know (US-A 4 691 964) which may fall out of the reach of the user seated in the seat, disappear between the cushions when the user is not himself seated on it. These controls are not on the armrest (US-A 3,907,051), as is known, but below on the face 59, or behind on the face 60, as shown in FIGS. 6 and 7.

La figure 8 montre une version préférée de l'invention où les boutons sont situés sur la face supérieure 61, dissimulés sous la garniture de l'accoudoir qui peut se soulever en totalité, ou partiellement, ce qui offre les avantages d'une esthétique intacte et l'impossibilité de manoeuvres indésirables par appui involontaire du bras de l'utilisateur. A titre d'exemple la garniture de l'accoudoir pivote sur un de ses côtés offrant la possibilité d'une petite tablette 49 pouvant recevoir rafraichissements, cendrier, petit écritoire, ou tout autres accessoires ; les télécommandes peuvent aussi être réparties dans les deux accoudoirs et on peut y ajouter d'autres télécommandes : chaine HI FI, télévision,etc... ou d'autres accessoires : allume-cigare etc...FIG. 8 shows a preferred version of the invention where the buttons are located on the upper face 61, hidden under the trim of the armrest which can be lifted entirely, or partially, which offers the advantages of intact aesthetics and the impossibility of unwanted maneuvers by involuntary support of the user's arm. For example, the armrest trim pivots on one of its sides, offering the possibility of a small shelf 49 which can receive refreshments, ashtray, small writing desk, or any other accessory; the remote controls can also be distributed in the two armrests and one can add other remote controls: HI FI chain, television, etc ... or other accessories: cigarette lighter etc ...

La figure 9 se rapporte à une mécanique simplifiée, variante de la présente invention, où deux actionneurs seulement sont nécéssaires, l'actionneur de l' assise étant supprimé, le mouvement de celle-ci étant lié séquentiellement à celui du repose-pieds. Cette disposition a l'avantage de déployer le repose-pieds quand la hauteur de son passage est maximum, donc sans risques de heurter le sol. Dans ce but le mouvement du chassis mobile est précontraint par les ressorts 50. Lorsque l'actionneur du repose-pieds 31 , articulé sur le chassis fixe 10 en 51 se développe, le chassis mobile 11 s'incline jusqu'à une position définie par la butée 52 sans que le repose-pieds ne bouge, puis ce dernier se développe à son tour jusqu'à l'inclinaison souhaitée. On notera que les biellette 26 et 27 sont également plus simples ,et que la butée 52 peut être placée pour bloquer le chassis 11 ou la biellette 12 ou la biellette 13 cas montré ici à titre d'exemple.FIG. 9 relates to a simplified mechanism, a variant of the present invention, where only two actuators are necessary, the seat actuator being eliminated, the movement of the latter being linked sequentially to that of the footrest. This arrangement has the advantage of deploying the footrest when the height of its passage is maximum, therefore without risk of hitting the ground. For this purpose, the movement of the mobile chassis is prestressed by the springs 50. When the footrest actuator 31, articulated on the fixed chassis 10 at 51 develops, the mobile chassis 11 tilts to a position defined by the stop 52 without the footrest moving, then the latter in turn develops to the desired inclination. It will be noted that the link 26 and 27 are also simpler, and that the stop 52 can be placed to block the frame 11 or the link 12 or the link 13 as shown here by way of example.

La figure 10 montre une vue partielle de l'ensemble mécanique simplifié dans le cas où l'on veut une position chaise longue. Dans le but de sinplification, les biellettes 26 et 27 sont droites. Un petit actionneur 53 appuie une biellette de blocage 54 contre la biellette motrice 26. Le blocage ne peut se faire que lorsque le repose-pieds est aligné avec l'assise ; dans ce cas et simultanément le mouvement de l'actionneur 31 est inversé et le mouvement se poursuit jusqu'à l'inclinaison souhaitée.FIG. 10 shows a partial view of the simplified mechanical assembly in the case where a chaise longue position is desired. For the purpose of simplification, the links 26 and 27 are straight. A small actuator 53 presses a locking rod 54 against the driving rod 26. The locking can only be done when the footrest is aligned with the seat; in this case and simultaneously the movement of the actuator 31 is reversed and the movement continues until the desired inclination.

La figure 11 montre une variante du système de blocage de la biellette 26 où un pène 64 mu par un actionneur peut sortir du chassis mobile 11 pour venir dans la gâche 65 dès que la biellette 26 est en position pour que l'ensemble soit en position chaise longue.Figure 11 shows a variant of the rod 26 locking system where a bolt 64 mu by an actuator can come out of the movable frame 11 to come into the keeper 65 as soon as the rod 26 is in position so that the assembly is in position lounge chair.

La figure 12 montre un autre mécanisme pour obtenir la position chaise longue cette fois sans retour arrière. Une butée mobile 66 actionnée par la biellette 26 du repose-pieds par l'intermédiaire d'une biellette supplémentaire 67 laisse échapper la butée 52. Le mouvement de l'assise se poursuit alors vers l'avant, et la forme particulière de la butée 66 maintient l'ensemble en position chaise longue.Figure 12 shows another mechanism to obtain the deckchair position this time without backtracking. A movable stop 66 actuated by the link 26 of the footrest via an additional link 67 lets escape the stop 52. The movement of the seat then continues forward, and the particular shape of the stop 66 keeps the unit in the chaise longue position.

La figure 13 montre un fauteuil contemporain selon l'invention, auquel on a ajouté un mouvement de rotation selon un axe vertical entre l'assise 62 et le piètement 63 par l'intermédiaire d'un actionneur 55.FIG. 13 shows a contemporary armchair according to the invention, to which a rotational movement has been added along a vertical axis between the seat 62 and the base 63 by means of an actuator 55.

La figure 14 montre un fauteuil transformable selon l'invention pour personnes handicapées. Il est muni de deux moteurs 56 situés sur les pieds arrières qui permettent de se déplacer, ainsi que de deux accoudoirs articulés en 57 et 58 sur chacun des pieds d'accoudoir au niveau du chassis fixe, ce qui permet de les escamoter en position lit.Figure 14 shows a convertible chair according to the invention for disabled people. It is equipped with two motors 56 located on the rear legs which allow movement, as well as two armrests articulated at 57 and 58 on each of the armrest legs at the level of the fixed frame, which allows them to be retracted in the bed position .
