Description

La présente invention concerne l'industrie des appareils médicaux et porte sur un fauteuil roulant à propulsion manuelle, constitué d'un siège relié à un châssis reposant sur des roues, dont le mode de conception permet d'offrir à l'utilisateur un plus grand confort et davantage d'autonomie par rapport aux dispositifs usuels.The present invention relates to the medical device industry and relates to a manually powered wheelchair, consisting of a seat connected to a chassis resting on wheels, whose design mode allows to offer the user a larger comfort and more autonomy compared to the usual devices.

En effet, les fauteuils roulants couramment utilisés à l'heure actuelle par les personnes à mobilité réduite, dans un cadre quotidien, se distinguent par leur structure sommaire présentant de nombreux inconvénients.In fact, the wheelchairs currently used by persons with reduced mobility, in a daily setting, are distinguished by their summary structure with many disadvantages.

Ainsi, le châssis se révèle généralement non seulement volumineux et encombrant, mais comprend également des éléments entravant les mouvements de l'utilisateur, tels que notamment deux barres destinées à maintenir le dos et gênant les gestes latéraux.Thus, the chassis is generally not only bulky and cumbersome, but also includes elements impeding the user's movements, such as including two bars to maintain the back and hindering lateral movements.

En outre, le siège, dont l'assise est classiquement définie par une simple toile tendue, n'offre aucun confort.In addition, the seat, whose seat is conventionally defined by a simple stretched canvas, offers no comfort.

D'autre part, du fait d'un châssis rigide, tous les chocs résultant du déplacement du fauteuil roulant sur des surfaces cahoteuses ou inégales, telles que des pavés ou des descentes de trottoirs, sont ressentis par la colonne vertébrale de l'utilisateur.On the other hand, because of a rigid chassis, all the impacts resulting from the wheelchair moving on bumpy or uneven surfaces, such as paving stones or sidewalk descents, are felt by the user's spine.

Enfin ces fauteuils, destinés à une utilisation ordinaire, ne sont pas adaptés à des usages dans des environnements variés et ne permettent généralement pas d'accéder aisément à des zones non goudronnées.Finally these chairs, for ordinary use, are not suitable for use in various environments and generally do not allow easy access to unpaved areas.

L'on connaît à l'heure actuelle également des fauteuils roulants spécialement étudiés pour la pratique de certaines disciplines sportives, dont les structures permettent davantage de liberté de mouvement, sont très stables, très compactes et très confortables. Cependant, ces fauteuils sont très onéreux car ils nécessitent une grande technicité et l'utilisation de matériaux sophistiqués aptes à répondre aux contraintes de la discipline sportive considérée, ce qui se révèle évidemment superflu et inadapté dans le cadre d'une utilisation au quotidien.Wheelchairs specially designed for the practice of certain disciplines are also known at present. sports, whose structures allow more freedom of movement, are very stable, very compact and very comfortable. However, these chairs are very expensive because they require great technicality and the use of sophisticated materials able to meet the constraints of the sports discipline in question, which is obviously superfluous and unsuitable in the context of everyday use.

Une solution supposée pallier ces différents inconvénients est notamment connue du document FR 2 799 641 . Elle consiste à équiper un fauteuil roulant d'une part d'un siège articulé dont la structure est étudiée pour épouser au plus près la morphologie de l'utilisateur, et d'autre part d'un châssis peu encombrant équipé d'un amortisseur apte à atténuer les chocs, et dont la structure permet une certaine polyvalence par rapport à différents environnements d'utilisation, en permettant notamment de faire varier le carrossage de roues arrière.A solution supposed to overcome these various disadvantages is particularly known from the document FR 2 799 641 . It consists of equipping a wheelchair with an articulated seat whose structure is designed to fit the user's morphology as closely as possible, and a space-saving chassis equipped with a suitable shock absorber. to mitigate shocks, and whose structure allows a certain versatility with respect to different environments of use, allowing in particular to vary the camber of the rear wheels.

Ainsi, plus précisément, le châssis est constitué d'une part, d'un cadre central coudé défini par une partie supérieure sensiblement horizontale supportant le siège et une potence sensiblement verticale portant à son extrémité inférieure au moins un moyen d'appui avant tel qu'une roue orientable, et d'autre part un balancier portant deux roues arrière, monté pivotant sur ledit cadre central et de plus relié à celui-ci au travers d'un moyen amortisseur, ledit balancier présentant deux bras qui s'étendent de part et d'autre de l'axe dudit châssis et qui portent chacun en extrémité l'une desdites deux roues arrière, les extrémités desdits bras étant usinées en sorte d'autoriser deux emplacements de fixation correspondant chacun à un angle de carrossage.Thus, more specifically, the frame is constituted firstly of a central bent frame defined by a substantially horizontal upper portion supporting the seat and a substantially vertical bracket carrying at its lower end at least one front support means such that a steerable wheel, and secondly a rocker carrying two rear wheels, pivotally mounted on said central frame and further connected thereto through damping means, said balance having two arms which extend from and other axis of said frame and which each end at one of said two rear wheels, the ends of said arms being machined so as to allow two mounting locations each corresponding to a camber angle.

Cette architecture n'apporte cependant toujours pas totale satisfaction, notamment en raison d'un poids élevé, d'une structure dont la tenue mécanique se révèle médiocre à l'usage et d'un coût de fabrication élevé du fait de la nécessité d'usiner un grand nombre de pièces.However, this architecture does not always provide total satisfaction, especially because of a high weight, a structure whose mechanical strength is mediocre to use and a high manufacturing cost due to the need to machine a large number of parts.

Par ailleurs, les roues arrière sont indépendantes de la roue avant, ce qui, lors des mouvements d'oscillation du balancier, pose un problème de verticalité de l'arbre qui porte la roue avant et qui permet de l'orienter, ce qui, outre les risques d'endommagement dudit arbre, peut constituer une entrave au roulage. Le même problème peut également se poser si le moyen d'appui avant est un patin ou analogue.Furthermore, the rear wheels are independent of the front wheel, which, during oscillating movements of the balance, poses a problem of verticality of the shaft which carries the front wheel and which allows to orient it, which, in addition to the risk of damage to said shaft, may constitute an obstacle to rolling. The same problem can also arise if the front support means is a pad or the like.

On connaît déjà des fauteuils roulants à structure déformable, permettant d'améliorer le confort de l'utilisateur. C'est notamment le cas de celui décrit dans le document NL 9 400 853 , dont la structure est articulée au moyen d'un vérin à gaz, afin de permettre de faire monter ou descendre l'utilisateur. Toutefois, un tel fauteuil ne permet que la modification de l'assise par rapport au châssis, il n'autorise pas l'adaptation du châssis à la forme du terrain.Wheelchairs with a deformable structure are already known, making it possible to improve the comfort of the user. This is particularly the case of the one described in the document NL 9,400,853 , whose structure is articulated by means of a gas cylinder, to allow to raise or lower the user. However, such a chair only allows the modification of the seat relative to the chassis, it does not allow the adaptation of the chassis to the shape of the ground.

La présente invention a donc pour but de proposer un fauteuil roulant adapté à un usage quotidien, dont la structure, parfaitement adaptée à la morphologie de l'utilisateur, apporte du confort et de l'aisance dans les déplacements, ainsi qu'une certaine polyvalence d'utilisation, tout en conservant sa stabilité au fil des utilisations et des variations de terrain.The present invention therefore aims to provide a wheelchair suitable for everyday use, whose structure, perfectly adapted to the morphology of the user, provides comfort and ease in travel, as well as a certain versatility of use, while maintaining its stability over uses and variations of terrain.

Le fauteuil roulant selon l'invention comprend un siège relié à un châssis reposant sur des roues, où ledit châssis comprend :

  • un cadre central coudé défini par une partie supérieure sensiblement horizontale supportant ledit siège et une potence sensiblement verticale portant à son extrémité inférieure au moins un moyen d'appui avant tel qu'une roue orientable,
  • et un balancier qui, d'une part est monté pivotant sur la potence dudit cadre central par l'intermédiaire d'un palier; d'autre part est relié audit cadre central travers d'un moyen amortisseur; et d'autre part encore porte deux roues arrières et présente à cet effet deux bras qui s'étendent de part et d'autre de l'axe dudit châssis et qui portent chacun en extrémité l'une desdites roues arrière, ledit fauteuil se caractérise essentiellement en ce que ledit moyen d'appui avant est relié à l'extrémité de ladite potence au travers d'une pièce montée sur ladite extrémité de manière pivotante selon un axe horizontal et transversal, ladite pièce étant de plus liée audit balancier par l'intermédiaire d'une bielle apte à permettre la transmission à ladite pièce de la variation d'angle entre ledit balancier et ladite potence.
The wheelchair according to the invention comprises a seat connected to a frame resting on wheels, wherein said chassis comprises:
  • a central bent frame defined by a substantially horizontal upper portion supporting said seat and a substantially vertical stem carrying at its lower end at least one front support means such as a steerable wheel,
  • and a balance which, on the one hand, is pivotally mounted on the bracket of said central frame by means of a bearing; on the other hand is connected to said central frame through a damping means; and on the other hand still carries two rear wheels and presents for this purpose two arms which extend on both sides of the axis of said frame and which each carry at the end one of said rear wheels, said chair is essentially characterized in that said front support means is connected to the end of said stem through a room mounted on said end pivotally along a horizontal and transverse axis, said part being further connected to said beam by means of a connecting rod adapted to allow the transmission to said piece of the angle variation between said beam and said stem.

Selon l'invention, le moyen d'appui avant est relié au balancier au travers d'une structure de type parallélogramme déformable, en sorte que son orientation est liée à celle dudit balancier.According to the invention, the front support means is connected to the balance beam through a deformable parallelogram-type structure, so that its orientation is linked to that of said balance.

Selon une caractéristique additionnelle du fauteuil selon l'invention le moyen d'appui consiste en une roue montée dans une chape reliée à la pièce pivotante au travers d'un pivot d'axe perpendiculaire à celui de rotation de ladite roue, lequel pivot est apte à tourillonner sur la pièce pivotante.According to an additional feature of the chair according to the invention the support means consists of a wheel mounted in a yoke connected to the pivoting part through a pin axis perpendicular to that of rotation of said wheel, which pivot is fit to spin on the pivoting part.

Selon une autre caractéristique additionnelle du fauteuil selon l'invention le balancier et le cadre central consistent en des profilés tubulaires en alliage léger.According to another additional feature of the chair according to the invention the balance and the central frame consist of tubular sections of light alloy.

Selon une variante, le balancier et le cadre central sont réalisés en un matériau composite moulé, ledit matériau étant de type fibres noyées dans une matrice thermodurcissable ou thermoplastique.According to a variant, the balance and the central frame are made of a molded composite material, said material being of the fiber type embedded in a thermosetting or thermoplastic matrix.

Selon une autre caractéristique additionnelle du fauteuil selon l'invention le balancier est essentiellement en forme de U, il comporte deux bras s'étendant chacun de part et d'autre de l'axe du châssis, et une traverse munie de deux pattes permettant la liaison avec le cadre au travers d'un arbre de pivotement.According to another additional feature of the chair according to the invention the balance is substantially U-shaped, it comprises two arms each extending on either side of the axis of the frame, and a crossbar provided with two legs allowing the connection with the frame through a pivot shaft.

Les avantages et les caractéristiques du dispositif selon l'invention, ressortiront plus clairement de la description qui suit et qui se rapporte au dessin annexé, lequel en représente un mode de réalisation non limitatif.The advantages and characteristics of the device according to the invention will become clearer from the description which follows and which refers to the attached drawing, which represents a non-limiting embodiment.

La présente invention a pour objet un fauteuil roulant à propulsion manuelle spécialement étudié pour offrir à l'utilisateur une parfaite maniabilité quels que soient les environnements d'utilisation, ainsi qu'un grand confort.The present invention relates to a wheelchair with manual propulsion specially designed to provide the user with perfect handling in all operating environments, as well as a high level of comfort.

De manière classique, un fauteuil roulant comprend un siège, non représenté, porté par un châssis 1 reposant sur des roues.In a conventional manner, a wheelchair comprises a seat, not shown, carried by a frame 1 resting on wheels.

Conformément à l'invention, et tel que visible sur les figures 1, 2 et 3, le châssis 1 comprend d'une part un cadre central coudé 2 défini par une barre supérieure 20 apte à supporter le siège, et une potence 21 apte à porter une roue avant 3, et, d'autre part, un balancier 4 monté pivotant sur le cadre central 2 et supportant des roues arrière 5 et 6.According to the invention, and as visible on the Figures 1, 2 and 3 , the frame 1 comprises on the one hand a central bent frame 2 defined by an upper bar 20 adapted to support the seat, and a bracket 21 adapted to carry a front wheel 3, and, on the other hand, a rocker 4 pivotally mounted on the central frame 2 and supporting rear wheels 5 and 6.

La roue avant 3 est du type orientable, c'est-à-dire qu'elle est montée dans une chape 30 montée pivotante sur un pivot 31 dont l'axe est perpendiculaire à celui de rotation de la roue 3, et de préférence vertical.The front wheel 3 is of the steerable type, that is to say it is mounted in a yoke 30 pivotally mounted on a pivot 31 whose axis is perpendicular to that of rotation of the wheel 3, and preferably vertical .

Le balancier 4 est essentiellement en forme de U, il comporte deux bras 40 et 41, s'étendant chacun de part et d'autre de l'axe du châssis 1, les bras 40, 41 étant munis chacun, au niveau de leurs extrémités libres, de deux emplacements 42, 43 de fixation d'une roue arrière 5, 6, qui définissent chacun un angle de carrossage.The balance 4 is essentially U-shaped, it comprises two arms 40 and 41, each extending on either side of the axis of the frame 1, the arms 40, 41 being each provided, at their free ends, two locations 42, 43 for fixing a rear wheel 5, 6, each defining a camber angle.

Les bras 40 et 41 sont réunis par une traverse 44 munie de deux pattes 45 et 46 qui s'étendent selon des plans parallèles à l'axe du châssis 1, et qui sont destinées à porter un arbre 7 permettant une liaison articulée du balancier 4 sur le cadre central 2, qui comporte à cet effet, sur la potence 21 à proximité de son rattachement à la barre supérieure 20, un palier 23.The arms 40 and 41 are joined by a crossbar 44 provided with two tabs 45 and 46 which extend in planes parallel to the axis of the frame 1, and which are intended to carry a shaft 7 allowing an articulated connection of the balance 4 on the central frame 2, which comprises for this purpose, on the bracket 21 near its attachment to the upper bar 20, a bearing 23.

On notera de plus que, dans un but de rigidifier la structure, les deux bras 40 et 41 sont, à proximité de leurs extrémités libres, entretoisés par une barre transversale 47. par ailleurs, le balancier 4 et le cadre central 2 consistent de préférence en des structures tubulaires en alliage léger, ou bien en matériau composite moulé, incorporant des fibres de verre, de carbone ou d'aramide, par exemple.Note further that, in order to stiffen the structure, the two arms 40 and 41 are, near their free ends, braced by a transverse bar 47. Furthermore, the balance 4 and the central frame 2 preferably consist of tubular structures of light alloy, or of molded composite material incorporating glass fiber, carbon fiber or aramid, for example.

Le balancier 4 et le cadre central 2, ou plus exactement la barre supérieure 20, sont reliés par des moyens amortisseurs 8 qui peuvent être prévus de dureté réglable, tandis que le point de fixation des moyens amortisseurs sur la barre supérieure 20 consiste en une bride coulissante 24 pour permettre, par le réglage de son positionnement, de faire varier la hauteur d'assise.The rocker 4 and the central frame 2, or more precisely the upper bar 20, are connected by damping means 8 which can be provided with adjustable hardness, while the point of attachment of the damping means on the upper bar 20 consists of a flange sliding 24 to allow, by adjusting its positioning, to vary the seat height.

Selon l'invention, la roue avant 3 est liée à la potence 21 au travers d'une plaque ou analogue 25, apte à pivoter sur cette potence 21 sur un pivot 26, cette plaque 25 étant de plus liée au balancier 4 par l'intermédiaire d'une bielle 27.According to the invention, the front wheel 3 is connected to the bracket 21 through a plate or the like 25, able to pivot on this bracket 21 on a pivot 26, this plate 25 being further connected to the balance 4 by the intermediate of a connecting rod 27.

La plaque 25, la potence 21, le balancier 4 et la bielle 27 constituent une structure de type parallélogramme déformable qui permet au pivot 31 de conserver la verticalité de son axe quel que soit l'angle formé par le balancier 4 et le cadre 2.The plate 25, the bracket 21, the balance 4 and the connecting rod 27 constitute a deformable parallelogram structure which allows the pivot 31 to maintain the verticality of its axis regardless of the angle formed by the balance 4 and the frame 2.
