Abstract
Description
Assise de siège, notamment de fauteuil roulant pour handicapé
La présente invention concerne une assise de siège, notamment de fauteuil roulant pour handicapé, comprenant une toile supportée par deux tringles latérales dont les extrémités sont respectivement tournées vers l'avant et vers l'arrière du siège.Seat, especially wheelchair for disabled
The present invention relates to a seat cushion, in particular a wheelchair for the disabled, comprising a fabric supported by two lateral rods, the ends of which face the front and rear of the seat respectively.
Il n'est pas possible actuellement de régler avec précision la tension de la toile utilisée pour réaliser l'assise de certains sièges. It is not currently possible to precisely adjust the tension of the fabric used to seat certain seats.
La présente invention se propose de remédier à cette lacune et, pour ce faire, elle a pour objet une assise qui se caractérise en ce qu'elle comporte des moyens pour régler la tension de la toile, ces moyens exerçant leur fonction de préférence en assurant une modification de la position relative des deux tringles. The present invention proposes to remedy this gap and, to do this, it relates to a seat which is characterized in that it comprises means for adjusting the tension of the fabric, these means exercising their function preferably by ensuring a modification of the relative position of the two rods.
Afin de répondre au mieux aux exigences des utilisateurs, les moyens de réglage peuvent être prévus au niveau des extrémités antérieures et/ou des extrémités postérieures des tringles. In order to best meet user requirements, the adjustment means can be provided at the front ends and / or the rear ends of the rods.
Selon un mode d'exécution préféré de l'invention, les moyens de réglage comprennent une tige s'étendant perpendiculairement arx tringles et dont les extrémités sont filetées en sens inverse, deux coulisseaux vissés sur les extrémités filetées de la tige, ces coulisseaux étant immobilisés en rotation mais libres en translation, deux leviers coudés montés pivotants sur deux axes perpendiculaires à la tige, l'une des extrémités de ces leviers coudés étant logée dans une encoche ménagée dans un coulisseau tandis que leur autre extrémité comporte un orifice dans lequel est enfilée l'une des extrémités d'une tringle, deux supports sur lesquels prennent appui les axes des leviers coudés, et un organe de commande pour faire tourner la tige. According to a preferred embodiment of the invention, the adjustment means comprise a rod extending perpendicularly with rods and the ends of which are threaded in opposite directions, two sliders screwed onto the threaded ends of the rod, these sliders being immobilized in rotation but free in translation, two bent levers pivotally mounted on two axes perpendicular to the rod, one end of these bent levers being housed in a notch in a slide while their other end has an orifice in which is threaded one of the ends of a rod, two supports on which bear the axes of the bent levers, and a control member for rotating the rod.
En faisant tourner la tige de manière à rapprocher les coulisseaux, on éloigne les extrémités des tringles qui sont en prise avec les leviers coudés et l'on assure ainsi la tension de la toile au niveau de ces extrémités. By rotating the rod so as to bring the slides together, the ends of the rods which are engaged with the bent levers are moved away and the tension of the fabric is thus ensured at these ends.
En revanche, si l'on fait tourner la tige en sens inverse, on diminue la tension de la toile au niveau des extrémités des tringles qui sont en prise avec les leviers coudés.On the other hand, if the rod is rotated in the opposite direction, the tension of the fabric is reduced at the ends of the rods which are engaged with the bent levers.
En prévoyant des moyens de réglage aussi bien au niveau des extrémités antérieures qu'au niveau des extrémités postérieures des tringles, on peut donner à la toile des inclinaisons très diverses vers l'avant ou vers l'arrière, ce qui permet à l'utilisateur de se tenir assis dans la position qui lui est la plus confortable. By providing adjustment means both at the anterior ends and at the posterior ends of the rods, the fabric can be given very different inclinations towards the front or towards the rear, which allows the user to sit in the most comfortable position.
D'autres caractéristiques et avantages de la présente invention ressortiront de la description qui sera donnée ci-après à titre d'exemple nullement limitatif en référence au dessin annexé dans lequel
la figure 1 est une vue en perspective d'une assise conforme à l'invention ; et
la figure 2 est une vue en coupe des moyens de réglage prévus au niveau de l'extrémité antérieure des tringles.Other characteristics and advantages of the present invention will emerge from the description which will be given below by way of nonlimiting example with reference to the appended drawing in which
Figure 1 is a perspective view of a seat according to the invention; and
Figure 2 is a sectional view of the adjusting means provided at the front end of the rods.
L'assise de siège que l'on peut voir sur le dessin comprend une toile 1 comportant deux ourlets parallèles réalisés le long de deux de ses cô- tés, cette toile étant supportée par deux tringles latérales 2 enfilées dans ses ourlets et dont les extrémités sont respectivement tournées vers l'avant et vers l'arrière du siège (non représenté,. The seat cushion that can be seen in the drawing comprises a fabric 1 comprising two parallel hems produced along two of its sides, this fabric being supported by two lateral rods 2 threaded in its hems and the ends of which are respectively facing the front and rear of the seat (not shown ,.
Elle comprend également des moyens 3 permettant de régler la tension de la toile 1 en modifiant la position relative des deux tringles 2. It also includes means 3 making it possible to adjust the tension of the fabric 1 by modifying the relative position of the two rods 2.
Dans l'exemple de réalisation représenté sur la figure 1, les moyens 3 sont prévus aussi bien au niveau des extrémités antérieures qu'au niveau des extrémités postérieures des tringles. il va de soi cependant que ces moyens pourraient n'être prévus qu au niveau des extrémités antérieures ou des extrémités postérieures des tringles. In the embodiment shown in Figure 1, the means 3 are provided both at the front ends and at the rear ends of the rods. it goes without saying, however, that these means could only be provided at the anterior ends or the posterior ends of the rods.
En se référant plus particulièrement à la figure 2, on remarquera que les moyens 3 comprennent une tige 4 s'étendant perpendiculairement aux tringles 2et dont les extrémités sont filetées en sens inverse ^ deux coulisseaux 5 vissés sur les extrémités filetées de la tige 4, ces coulisseaux étant immobilisés en rotation mais libres en translation, deux leviers coudés 6 montés pivotants sur deux axes 7 perpendiculaires à la tige 4, l'extrémité inférieure 8 des leviers coudés 6 étant logée dans une encoche 9 ménagée dans un coulisseau tandis que leur extrémité supérieure 10 comporte un orifice 11 dans lequel est enfilée et retenue l'une des extrémités d'une tringle 2, deux supports 12 dont l'extrémité supérieure est constituée de deux pattes parallèles sur lesquelles prennent appui les axes 7 des leviers coudés, et un manchon 13 immobilisé sur la tige 4 par l'intermédiaire d'une vis pointeau 14, ce manchon étant moleté sur sa face latérale pour qu'un utilisateur puisse faire tourner plus facilement la tige 4. Referring more particularly to FIG. 2, it will be noted that the means 3 comprise a rod 4 extending perpendicularly to the rods 2 and the ends of which are threaded in opposite directions ^ two slides 5 screwed onto the threaded ends of the rod 4, these sliders being immobilized in rotation but free in translation, two bent levers 6 pivotally mounted on two axes 7 perpendicular to the rod 4, the lower end 8 of the bent levers 6 being housed in a notch 9 formed in a slider while their upper end 10 comprises an orifice 11 in which is threaded and retained one of the ends of a rod 2, two supports 12 whose upper end consists of two parallel legs on which the axes 7 of the bent levers bear, and a sleeve 13 immobilized on the rod 4 by means of a needle screw 14, this sleeve being knurled on its lateral face so that a user can rotate more f acutely the rod 4.
La tige 4 et les coulisseaux 5 sont logés dans un tube 15 reliant les supports 12, ce tube étant pourvu sur sa face inférieure d'une lumière cen trale 16 livrant passage au manchon 13 et sur sa face supérieure de deux lumières latérales 17 livrant passage aux extrémités supérieures des leviers coudés. The rod 4 and the slides 5 are housed in a tube 15 connecting the supports 12, this tube being provided on its underside with a central lumen 16 delivering passage to the sleeve 13 and on its upper face with two lateral lumens 17 delivering passage at the upper ends of the bent levers.
Les moyens de réglage prévus au niveau de l'extrémité postérieure des tringles ont la même structure que ceux qui sont prévus au niveau de leur extrémité antérieure et il est donc inutile de les décrire ici. The adjustment means provided at the rear end of the rods have the same structure as those provided at their front end and it is therefore unnecessary to describe them here.
Bien que le fonctionnement des moyens de réglage 3 soit évident, on indiquera toutefois que pour tendre la toile 1, on fait tourner la tige 4 de façon à rapprocher les coulisseaux 5 l'un de l'autre et par suite à faire pivoter les leviers coudés dans le sens des flèches F1 et F2 sur la figure 2. Although the operation of the adjustment means 3 is obvious, it will however be indicated that in order to tension the fabric 1, the rod 4 is made to rotate so as to bring the sliders 5 together and consequently rotate the levers bent in the direction of arrows F1 and F2 in Figure 2.
il suffira bien entendu de tourner la tige 4 en sens inverse pour détendre la toile 1. it will of course suffice to turn the rod 4 in the opposite direction to relax the fabric 1.
Etant donné que l'assise représentée sur le dessin comporte des moyens de réglage 3 au niveau des extrémités antérieures et postérieures des tringles 2, on conçoit aisément qu'en actionnant judicieusement ces moyens, on peut donner des inclinaisons très diverses à la toile, ce qui permet de régler cette dernière dans la position qui est la plus confortable pour l'utilisateur. Given that the seat shown in the drawing comprises adjustment means 3 at the front and rear ends of the rods 2, it is easily understood that by judiciously actuating these means, it is possible to give very different inclinations to the fabric, this which allows the latter to be adjusted to the position which is most comfortable for the user.
L'assise qui vient d'entre décrite est plus particulièrement destinée à un fauteuil roulant pour handicapé, notamment pour enfant. Elle pourrait toutefois, moyennant quelques légères modifications, etre adaptée sur n'importe quel siège. The seat which has just been described is more particularly intended for a wheelchair for the disabled, in particular for children. It could however, with a few slight modifications, be adapted to any seat.
On notera enfin que l'on ne sortirait pas du cadre de la présente invention Si l'on utilisait les moyens de réglage 3 sur des dossiers de siège comprenant à leur tour une toile supportée par deux tringles latérales. Finally, it will be noted that it would not go beyond the scope of the present invention If the adjustment means 3 were used on the seat backs, in their turn comprising a canvas supported by two lateral rods.
