Description
[L'invention est relative à un fauteuil roulant, en particulier électrique.[The invention relates to a wheelchair, in particular an electric wheelchair.
L'invention sera plus particulièrement décrite en regard d'un fauteuil roulant électrique d'extérieur, dit encore fauteuil roulant « outdoor », sans toutefois y être limitée. L'invention s'applique à tout fauteuil roulant autonome, électrique ou non, c'est-à-dire à un fauteuil roulant qui en utilisation est conduit sans aucun dispositif de traction ou de poussée qui serait attaché au fauteuil. Le fauteuil est à avancement manuel ou électrique.The invention will be more particularly described with regard to an outdoor electric wheelchair, also known as an “outdoor” wheelchair, without however being limited thereto. The invention applies to any autonomous wheelchair, electric or not, that is to say a wheelchair which in use is driven without any traction or pushing device which would be attached to the wheelchair. The chair is manually or electrically advanced.
Les fauteuils électriques d'extérieur sont des fauteuils tout terrain qui sont conçus avec des roues et un nombre de roues, adaptés au franchissement d'obstacles. Ils permettent de franchir les obstacles en ville tels que les trottoirs; ils sont manoeuvrables pour circuler dans l'herbe, les graviers, la neige, le sable, etc.Outdoor power chairs are all-terrain chairs that are designed with wheels and a number of wheels, suitable for crossing obstacles. They make it possible to overcome obstacles in the city such as sidewalks; they are maneuverable to move through grass, gravel, snow, sand, etc.
On cherche bien entendu à ce que l'accès au tout terrain, en particulier l'accès à une plage de sable, devienne possible au plus grand nombre parmi les personnes à mobilité réduite, âgées ou handicapées. Le fauteuil se doit d'être facilement transportable pour être amené jusqu'à l'endroit désiré.It is of course sought that access to all terrain, in particular access to a sandy beach, become possible for the greatest number of people with reduced mobility, elderly or disabled. The chair must be easily transportable to be brought to the desired location.
Toutefois, ces fauteuils d'extérieur sont lourds, généralement de poids de l'ordre de 40 kg jusqu'à 120 kg. Ils sont donc difficilement transportables. Leur transport est réalisé à l'aide de véhicules spéciaux dont l'intérieur est aménagé pour loger un tel fauteuil.However, these outdoor armchairs are heavy, generally weighing around 40 kg to 120 kg. They are therefore difficult to transport. They are transported using special vehicles, the interior of which is designed to accommodate such an armchair.
De plus, ces fauteuils sont généralement très chers à l'achat et ne sont donc pas accessibles à tous.In addition, these armchairs are generally very expensive to purchase and are therefore not accessible to everyone.
Par ailleurs, ces fauteuils aux composants multiples sont fastidieux à nettoyer, ce qui n'incite pas à leur utilisation dans des endroits au sol sableux (plages) ou boueux (forêts).Furthermore, these multi-component armchairs are tedious to clean, which does not encourage their use in places with sandy soil (beaches) or muddy (forests).
L'invention a donc pour but de proposer un fauteuil roulant, en particulier électrique et d'extérieur, qui soit aisément transportable, peu lourd pour être aisément soulevé, apte au tout terrain, tout en étant facile d'entretien. Le fauteuil roulant étant autonome dans son utilisation (lorsqu'un utilisateur est assis dessus pour se déplacer), l'invention vise non pas le déplacement du fauteuil mais son transport hors utilisation.The invention therefore aims to provide a wheelchair, especially electric and outdoor, which is easily transportable, light to be easily lifted, suitable for all terrain, while being easy to maintain. The wheelchair being autonomous in its use (when a user is seated on it to move around), the invention does not aim to move the chair but to transport it when not in use.
Selon l'invention, le fauteuil roulant, de préférence électrique, comporte un châssis, des roues, un siège, et est caractérisé en ce qu'il comporte un moyen de couplage pour attelage de véhicule (de couplage à un moyen d'attelage), le moyen de couplage étant de préférence solidaire du châssis.According to the invention, the wheelchair, preferably electric, comprises a chassis, wheels, a seat, and is characterized in that it comprises a coupling means for vehicle coupling (coupling to a coupling means) , the coupling means preferably being integral with the chassis.
Selon une caractéristique, le moyen de couplage pour attelage de véhicule est apte à se fixer sur une boule d'attelage de remorque de véhicule.According to one characteristic, the coupling means for vehicle coupling is adapted to be fixed on a vehicle trailer coupling ball.
Le moyen de couplage constitue un moyen de couplage pour porter le fauteuil (et le transporter).The coupling means constitutes a coupling means for carrying the chair (and transporting it).
Le moyen de couplage est configuré et agencé sur le fauteuil de sorte à porter le fauteuil, c'est-à-dire que le moyen de couplage est approprié pour élever l'ensemble/la totalité du fauteuil en position d'accouplement du fauteuil avec le moyen d'attelage du véhicule auquel est destiné le moyen de couplage.The coupling means is configured and arranged on the chair so as to carry the chair, that is to say that the coupling means is suitable for raising the whole / all of the chair to the position of coupling of the chair with the coupling means of the vehicle for which the coupling means is intended.
Ainsi, le fauteuil roulant dispose pour son transport de moyens d'attache/de couplage qui assurent un montage direct du fauteuil sur l'organe d'attelage d'un véhicule, telle qu'une boule d'attelage de remorque. Le fauteuil est alors très aisé à fixer/monter sur l'attelage, y compris de manière rapide, pour être positionné en hauteur par rapport au sol (sans toucher le sol)/être porté et être ainsi directement transportable. Aucun véhicule spécial de transport n'est nécessaire.Thus, the wheelchair has for its attachment / coupling means which ensure direct mounting of the chair on the coupling member of a vehicle, such as a trailer coupling ball. The chair is then very easy to fix / mount on the hitch, including quickly, to be positioned high above the ground (without touching the ground) / to be carried and thus be directly transportable. No special transport vehicle is required.
Selon une autre caractéristique, le moyen de couplage est disposé à l'arrière du fauteuil. Le moyen de couplage est disposé en saillie. Le moyen de couplage est disposé en particulier à une hauteur de l'ordre de 200 à 500 mm par rapport au plan de roulement du fauteuil (surface d'extrémité inférieure des roues).According to another characteristic, the coupling means is arranged at the rear of the chair. The coupling means is arranged projecting. The coupling means is arranged in particular at a height of the order of 200 to 500 mm relative to the rolling surface of the chair (lower end surface of the wheels).
Dans un exemple de mode de réalisation, le fauteuil roulant qui est autonome en utilisation, comporte le moyen de couplage qui est disposé à l'arrière du fauteuil et constitué d'un attelage de véhicule apte à se fixer sur une boule d'attelage de véhicule, le moyen de couplage étant utilisé pour porter et transporter le fauteuil hors utilisation en fixant le fauteuil directement sur la boule d'attelage.In an exemplary embodiment, the wheelchair which is autonomous in use, comprises the coupling means which is arranged at the rear of the wheelchair and consists of a vehicle coupling capable of being fixed on a coupling ball of vehicle, the coupling means being used to carry and transport the wheelchair out of use by fixing the wheelchair directly on the tow ball.
Selon une caractéristique préférée, le fauteuil ne comporte que deux roues à l'avant et au moins une roue à l'arrière (de préférence deux roues à l'arrière), de préférence les roues avant étant motrices et de plus grande dimension que la ou les roues arrière, de préférence au moins les roues avant possédant des pneus tout terrain.According to a preferred characteristic, the wheelchair has only two wheels at the front and at least one wheel at the rear (preferably two wheels at the rear), preferably the front wheels being driven and of larger dimension than the or the rear wheels, preferably at least the front wheels having all-terrain tires.
De préférence, les roues avant sont les roues motrices et de préférence présentent un diamètre de 24 pouces.Preferably, the front wheels are the drive wheels and preferably have a diameter of 24 inches.
Avantageusement, le siège est en matière plastique, de préférence en polyéthylène. La matière plastique est un revêtement facilement nettoyable, et qui répond aux obligations d'hygiène attendue, en particulier en cas de location du fauteuil, et qui n'est pas allergisant. En outre, la matière plastique permet de donner au siège la forme souhaitée.Advantageously, the seat is made of plastic, preferably polyethylene. The plastic is a coating that can be easily cleaned, and which meets the expected hygiene requirements, in particular in the case of rental of the chair, and which is not allergenic. In addition, the plastic makes it possible to give the seat the desired shape.
En particulier, le siège forme une coque, de préférence à laquelle sont associés latéralement deux garde-boue opposés chapotant les roues (avant) à l'avant du fauteuil.In particular, the seat forms a shell, preferably with which are associated laterally two opposite mudguards covering the wheels (front) at the front of the chair.
Selon une autre caractéristique, le fauteuil comporte un repose-pieds amovible ou mobile apte à être sorti vers l'avant du fauteuil en position d'utilisation, de préférence le repose-pieds comporte des moyens de butée et d'anti-basculement, tels que des roulettes.According to another characteristic, the chair comprises a removable or movable footrest capable of being taken out towards the front of the chair in the position of use, preferably the footrest comprises stop and anti-tilt means, such only wheels.
Le fauteuil comporte des moyens de maintien, de préhension et/ou de positionnement des mains, en particulier le siège comporte (vers l'avant dudit siège) au moins un organe en saillie qui présente de préférence une géométrie bombée (aux contours arrondis) telle qu'une boule ou un pommeau.The chair comprises means for holding, gripping and / or positioning the hands, in particular the seat comprises (towards the front of said seat) at least one projecting member which preferably has a convex geometry (with rounded contours) such than a ball or a pommel.
Le fauteuil peut comporter un arceau de préférence amovible, et éventuellement une capote, et/ou présente son siège inclinable et/ou pivotable. L'arceau peut servir de moyens de préhension, maintien et/ou de positionnement des mains, et de structure de fixation pour capote (par exemple de capote de protection contre la pluie). L'inclinaison du siège est par exemple effectuée par des moyens du type vérins.The chair may include a preferably removable hoop, and possibly a soft top, and / or has its reclining and / or swivel seat. The roll bar can serve as means of gripping, holding and / or positioning of the hands, and of a fixing structure for a hood (for example a hood for protection against rain). The seat is tilted for example by means of the actuator type.
De préférence, le fauteuil est électrique, notamment les batteries étant agencées sur une plateforme arrière et devant le moyen de couplage, ou bien sous le fauteuil.Preferably, the chair is electric, in particular the batteries being arranged on a rear platform and in front of the coupling means, or else under the chair.
Avantageusement, le fauteuil roulant est électrique et présente un poids d'au plus une vingtaine de kilogramme, de préférence d'au plus 20 kg, notamment du fait du choix des matériaux, d'un châssis épuré et du nombre de roues.Advantageously, the wheelchair is electric and has a weight of at most about twenty kilograms, preferably at most 20 kg, in particular due to the choice of materials, a refined chassis and the number of wheels.
L'invention porte également sur un procédé de transport du fauteuil roulant précité de l'invention et hors utilisation du fauteuil, le procédé comportant une étape d'élévation du fauteuil, par exemple de soulèvement manuel du fauteuil, et une étape d'accouplement/d'agencement du moyen de couplage du fauteuil en coopération avec un attelage de véhicule, en particulier une boule d'attelage d'un véhicule. Le fauteuil est fixé directement sur l'attelage. En position couplée du fauteuil sur l'attelage du véhicule, le fauteuil est en hauteur et à distance du sol. Le fauteuil ne touche pas le sol. Le fauteuil est en position portée et est surélevé (par rapport au sol, sans que ses roues ne touchent le sol) ; il peut alors être transporté.The invention also relates to a method of transporting the aforementioned wheelchair of the invention and without using the chair, the method comprising a step of raising the chair, for example of manual lifting of the chair, and a step of coupling / arrangement of the coupling means of the chair in cooperation with a vehicle hitch, in particular a vehicle hitch ball. The chair is attached directly to the hitch. In the coupled position of the chair on the vehicle hitch, the chair is high and at a distance from the ground. The chair does not touch the ground. The chair is in the carried position and is raised (off the ground, without its wheels touching the ground); it can then be transported.
Le procédé comporte une étape de verrouillage de l'accouplement du fauteuil sur l'attelage.The method includes a step of locking the coupling of the chair on the hitch.
Le procédé peut comporter une étape de protection du fauteuil, en particulier contre les intempéries, en le couvrant d'une bâche de protection.The method may include a step of protecting the chair, in particular against bad weather, by covering it with a protective cover.

Le moyen de couplage 5 est en saillie du reste du châssis 2.The coupling means 5 projects from the rest of the
Le moyen de couplage 5 est disposé à une hauteur supérieure à la surface de roulement, de préférence dans un plan horizontal situé dans le plan ou au-dessus du plan d'extrémité supérieur de la ou des roues arrière 4-3. Le moyen de couplage 5 est par exemple situé à une hauteur de l'ordre de 200 mm par rapport au plan d'extrémité inférieure des roues (de la surface de roulement du fauteuil).The coupling means 5 is disposed at a height greater than the running surface, preferably in a horizontal plane situated in the plane or above the upper end plane of the rear wheel or wheels 4-3. The coupling means 5 is for example located at a height of the order of 200 mm relative to the lower end plane of the wheels (of the rolling surface of the chair).
Tout moyen de couplage 5 pour se monter sur le moyen d'attelage d'un véhicule est envisageable. Par exemple, le moyen de couplage 5 comporte une pièce apte à coopérer avec une boule d'attelage de véhicule (apte à s'emmancher autour de la boule), et des organes de serrage et blocage en rotation du moyen de couplage, et éventuellement des moyens de verrouillage empêchant le démontage du moyen de couplage 5, et donc du fauteuil, sans avoir à disposition l'accessoire de déverrouillage du type clé.Any coupling means 5 for mounting on the coupling means of a vehicle is conceivable. For example, the coupling means 5 comprises a part able to cooperate with a vehicle coupling ball (able to be fitted around the ball), and clamping and rotation-blocking members of the coupling means, and possibly locking means preventing the disassembly of the coupling means 5, and therefore of the chair, without having the unlocking accessory of the key type available.
