L' invention est illustrée ci-après à l 'aide d'un exemple de réalisation et en référence aux dessins annexés , sur lesquels : les figures 1 et 2 sont des vues schématiques d'un dispositif de repose- jambes selon l'invention sans coussins, respectivement en coupe transversale en position repliée escamotée et en perspective en extension de service, et les figures 3 à 6 sont des vues schématiques montrant les diverses étapes de la mise en service de ce dispositif de repose- jambes .The invention is illustrated below with the aid of an exemplary embodiment and with reference to the accompanying drawings, in which: FIGS. 1 and 2 are schematic views of a legrest device according to the invention without cushions, respectively in cross section in the retracted retracted position and in perspective in service extension, and FIGS. 3 to 6 are schematic views showing the various stages of the putting into service of this legrest device.
Pour mieux voir les divers éléments constitutifs du dispositif de repose- jambes selon l ' invention, on l'a représenté aux figures 1 et 2 sans ses éléments de coussins . Le dispositif de repose- jambes selon l'invention comporte un
jeu de deux ferrures latérales parallèles 1, articulées à leur extrémité supérieure à la partie .-. nt de l'élément d'assise 3 du siège ou fauteuil équip*. h et un jeu de coulisses latérales parallèles 7, adjacentes chacune à une ferrure, et montées articulées et coulissantes à l'extrémité inférieure des ferrures. Les ferrures sont disposées de part et d'autre de l'élément d'assise 3 du fauteuil, étant articulées chacune dans un plan vertical latéral du fauteuil. Le plan d'articulation et de coulissèment des coulisses est le même que celui des ferrures, à savoir vertical et dans le prolongement de chacune des ferrures. Les ferrures sont identiques l'une à l'autre et consistent en une plaque de forme sensiblement triangulaire et dont le sommet A du triangle à l'arrière est sous l'élément d'assise 3 ou coussin d'assise du siège ou du fauteuil. Ces ferrures sont reliées rigidement à une plaque transversale 9 support d'un premier coussin 11 ou coussin supérieur du repose- jambes (figures 3-6). Cette plaque est rectangulaire, sensiblement de la largeur du coussin qu'elle reçoit. Celui- ci est monté avec la plaque noyée en son sein. Les coulisses 7 sont également reliées à une plaque 13 support d'un second coussin 15 ou coussin inférieur monté adjacent au premier. Cette plaque est également rectangulaire, de même largeur que le coussin associé et celui-ci est monté avec la plaque noyée en son sein. La largeur des deux coussins (dans le plan longitudinal du siège ou fauteuil) est sensiblement égale à la demi-longueur du repose-jambes en service (figure 5 et 6).To better see the various constituent elements of the legrest device according to the invention, it has been shown in Figures 1 and 2 without its cushion elements. The legrest device according to the invention comprises a set of two parallel lateral fittings 1, articulated at their upper end to the part .-. nt of the seat element 3 of the fitted seat or armchair * . h and a set of parallel lateral slides 7, each adjacent to a fitting, and mounted articulated and sliding at the lower end of the fittings. The fittings are arranged on either side of the seat element 3 of the chair, each being articulated in a vertical lateral plane of the chair. The plane of articulation and sliding of the slides is the same as that of the fittings, namely vertical and in the extension of each of the fittings. The fittings are identical to each other and consist of a plate of substantially triangular shape and the apex A of the triangle at the rear is under the seat element 3 or seat cushion of the seat or the armchair . These fittings are rigidly connected to a transverse plate 9 supporting a first cushion 11 or upper cushion of the legrest (Figures 3-6). This plate is rectangular, substantially the width of the cushion it receives. It is mounted with the plate embedded in it. The slides 7 are also connected to a plate 13 supporting a second cushion 15 or lower cushion mounted adjacent to the first. This plate is also rectangular, of the same width as the associated cushion and the latter is mounted with the plate embedded therein. The width of the two cushions (in the longitudinal plane of the seat or chair) is substantially equal to the half-length of the legrest in use (Figures 5 and 6).
Une bielle arrière 17 relie le jeu de coulisses 7 au jeu de ferrures 1. Cette bielle est articulée à la partie arrière du jeu de coulisses, dans son plan médian et au niveau de la partie de sommet A du jeu de ferrures également dans son plan médian. Cette bielle est donc en débattement dans un plan vertical médian du siège ou fauteuil, étant montée articulée à une patte inférieure arrière 19 solidaire de la plaque 13 du jeu de coulisses et à une patte supérieure 21 solidaire de la plaque 9 du jeu de ferrures.
L'ensemble cinématique constitué est donc analogue à un triangle articulé en section, monté suspendu à la partie avant de l'élément d'assise 3. Une tige arrière 23 disposée sous l'élément d'assise est reliée articulée à la biellette 17. Cette tige est animée en translation, en poussée ou en traction selon flèche, par un élément moteur, tel qu'un vérin à vis, monté solidaire du siège ou cadre du fauteuil.A rear connecting rod 17 connects the set of slides 7 to the set of fittings 1. This connecting rod is articulated at the rear part of the set of slides, in its median plane and at the level of the apex part A of the set of fittings also in its plane median. This connecting rod is therefore in movement in a vertical median plane of the seat or chair, being hinged to a rear lower tab 19 secured to the plate 13 of the set of slides and to an upper tab 21 secured to the plate 9 of the set of fittings. The kinematic assembly constituted is therefore analogous to a triangle articulated in section, mounted suspended from the front part of the seat element 3. A rear rod 23 disposed under the seat element is articulated connected to the link 17. This rod is driven in translation, pushing or pulling according to arrow, by a motor element, such as a screw jack, mounted integral with the seat or frame of the chair.
Le fonctionnement du repose-jambes est à présent précisé en relation avec les figures 3 à 6. A la figure 3, le repose- jambes est en position escamotée sous le siège ou fauteuil, replié dans l'espace libre sous l'élément d'assise 3 et entre les montants latéraux non représentés du cadre ou châssis du siège ou fauteuil. Le coussin supérieur 11 est disposé avec sa face avant en position sensiblement verticale. Le coussin inférieur 15 est complètement rentré vers l'arrière, sa face supérieure touchant le coussin supérieur et son bord avant vient dans le prolongement vertical de la face avant du coussin supérieur. Il est à faible distance du sol. Dans une première phase de déploiement (figure 4) du repose-jambes, correspondant à une poussée de la tige 23, selon flèche, le coussin inférieur 15 est mû seul vers l'avant en position sensiblement horizontale et à faible distance du sol, le jeu de coulisses 7 se translatant sur toute la longueur de coulisse disponible sur leur point d'articulation inférieur sur les ferrures. Dès qu'on a atteint cette course limite de coulissement, la tige continuant à pousser, le triangle articulé s'aplatit progressivement de sorte que les coussins 11 et 15 viennent en prolongement l'un de l'autre selon un même plan à un angle d'environ 40° de la verticale (figure 5). La bielle 17 de liaison arrière dans cette position bloque les plans supports de coussin dans un même plan (par appui des plans en butée sur celle-ci). Jusqu'à cette position, l'extrémité avant du coussin inférieur 15 est à faible distance du sol. La tige continuant à pousser, l'ensemble tourne alors sur l'axe d'articulation de la partie avant de l'élément
d'assise 3, les coussins demeurant dans un même plan et en continuité l'un de l'autre, jusqu'à une position limite supérieure, légèrement relevée par rapport à l'horizontale, représentée à la figure 6. Le débattement angulaire permis entre les positions des figures 5 et 6 correspond à la zone utile de service du repose-jambes où celui-ci peut être commandé en orientation variable à souhait par les personnes l'utilisant.The operation of the legrest is now specified in relation to FIGS. 3 to 6. In FIG. 3, the legrest is in the retracted position under the seat or chair, folded back into the free space under the element of seat 3 and between the side uprights, not shown, of the frame or chassis of the seat or chair. The upper cushion 11 is arranged with its front face in a substantially vertical position. The lower cushion 15 is completely retracted back, its upper face touching the upper cushion and its front edge comes in the vertical extension of the front face of the upper cushion. It is a short distance from the ground. In a first deployment phase (FIG. 4) of the legrest, corresponding to a thrust of the rod 23, according to arrow, the lower cushion 15 is moved alone forward in a substantially horizontal position and at a short distance from the ground, the set of runners 7 translating over the entire run length available at their lower point of articulation on the fittings. As soon as this sliding limit stroke is reached, the rod continuing to push, the articulated triangle progressively flattens so that the cushions 11 and 15 come in extension of one another in the same plane at an angle about 40 ° from the vertical (Figure 5). The rear link rod 17 in this position blocks the cushion support planes in the same plane (by pressing the plans in abutment thereon). Up to this position, the front end of the lower cushion 15 is a short distance from the ground. The rod continuing to push, the assembly then rotates on the hinge axis of the front part of the element seat 3, the cushions remaining in the same plane and in continuity with each other, up to an upper limit position, slightly raised relative to the horizontal, shown in FIG. 6. The angular movement allowed between the positions of FIGS. 5 and 6 corresponds to the useful service area of the legrest where it can be controlled in variable orientation as desired by the people using it.
Naturellement, le déplacement de la tige 23 dans le sens inverse à celui précité, provoque un mouvement symétrique à celui de l'extension de service jusqu'à la position hors service escamotée précitée sous le siège.Naturally, the displacement of the rod 23 in the opposite direction to that mentioned above, causes a movement symmetrical to that of the service extension to the above-mentioned retracted out-of-service position under the seat.
On notera par ailleurs que l'élément d'assise du siège ou fauteuil peut être mobile, selon un mouvement de faible amplitude, de translation ou d'orientation angulaire, accompagnant le mouvement du repose-jambes pour un confort optimal de support des jambes. La cinématique décrite fonctionne parfaitement.It will also be noted that the seat element of the seat or armchair can be mobile, according to a movement of small amplitude, of translation or of angular orientation, accompanying the movement of the legrest for optimal comfort of leg support. The kinematics described works perfectly.
Si l'élément d'assise reste fixe, le repose-jambes peut encore être monté articulé par ses ferrures 1 aux montants latéraux du cadre support du siège ou fauteuil, par exemple à ses éléments d'accoudoirs latéraux.If the seat element remains fixed, the legrest can also be mounted articulated by its fittings 1 to the lateral uprights of the support frame of the seat or armchair, for example to its lateral armrest elements.
On notera encore que les coussins peuvent être d'une épaisseur relativement importante, sans que la cinématique de triangle articulée soit empêchée. Ceci assure un bon confort de soutien des jambes (sans point de pression).It will also be noted that the cushions can be of relatively large thickness, without the kinematics of articulated triangle being prevented. This ensures good comfort in supporting the legs (without pressure point).
Par ailleurs, le coussin 11 peut être relié à un ressort arrière solidaire du cadre du siège ou fauteuil et le rappelant dans l'orientation verticale. Ce ressort en retenant le coussin favorise le coulissement du coussin 15 pour éviter que l'ensemble des deux coussins ne soit relevé en bloc sans coulissement préalable du coussin inférieur et de même le retour en position escamotée des coussins en assurant une action positive sur le coulissement du coussin inférieur à la limite inférieure de l'orientation de service. De même, l'extrémité avant du coussin coulissant inférieur peut être munie d'un tampon destiné à venir en
contact avec le sol pour favoriser le coulissement de ce coussin au cours de ce mouvement et inversement à son retour en position escamotée.
Furthermore, the cushion 11 can be connected to a rear spring secured to the frame of the seat or chair and recalling it in the vertical orientation. This spring while retaining the cushion promotes the sliding of the cushion 15 to prevent the assembly of the two cushions from being lifted as a whole without prior sliding of the lower cushion and likewise the return to the retracted position of the cushions while ensuring a positive action on the sliding cushion lower than the lower limit of service orientation. Similarly, the front end of the lower sliding cushion can be provided with a buffer intended to come in contact with the ground to favor the sliding of this cushion during this movement and vice versa when it returns to the retracted position.
