Abstract
Le fauteuil roulant comporte des roues motrices qui sont situées à l'avant et qui sont de grande tailles, et des roues arrière orientables qui peuvent être rapprochées des roues avant, ce qui a pour effet de faire basculer le fauteuil vers l'avant. Après ce basculement, le support des pieds de l'utilisateur touche le sol, ce qui facilite son embarquement et son débarquement. De grandes roues situées à l'avant ont aussi pour avantage de faciliter le franchissement d'obstacles. Les roues arrière peuvent être remplacées par une ou plusieurs chenilles.The wheelchair has large front-wheel drive wheels and steerable rear wheels that can be moved closer to the front wheels, causing the wheelchair to tip forwards. After this tilting, the support of the feet of the user touches the ground, which facilitates its embarkation and disembarkation. Large wheels at the front also have the advantage of facilitating the crossing of obstacles. The rear wheels can be replaced by one or more tracks.
Description
Fauteuil roulant à géométrie variableWheelchair with variable geometry
Domaine d’application L’invention est un fauteuil roulant inclinableField of application The invention is a reclining wheelchair
Problème posé L’objectif poursuivi par la présente invention est de réaliser un fauteuil roulant permettant un embarquement aisé du passager, ainsi qu’un meilleur franchissement des obstacles.Problem The objective of the present invention is to provide a wheelchair for easy boarding of the passenger, and a better obstacle clearance.
Description sommaire des dessins L’invention sera bien comprise, et d’autres buts, avantages et caractéristiques de celle-ci apparaîtront plus clairement à la lecture de la description qui va suivre, laquelle est illustrée par les figures 1 à 3 qui représentent toutes un fauteuil roulant selon l'invention.Brief description of the drawings The invention will be better understood, and other objects, advantages and characteristics thereof will appear more clearly on reading the description which follows, which is illustrated by FIGS. wheelchair according to the invention.
La figure 1 représente le fauteuil roulant en configuration de transport normal.Figure 1 shows the wheelchair in normal transport configuration.
La figure 2 représente le fauteuil roulant en configuration d’embarquement et de débarquementFigure 2 shows the wheelchair in embarkation and disembarkation configuration
La figure 3 représente le fauteuil roulant en configuration de transport semi allongé.Figure 3 shows the wheelchair in a semi-elongated transport configuration.
Exposé de l’invention L'invention est un fauteuil roulant caractérisé par le fait que son empattement est réglable et que la réduction dudit empattement a pour conséquence un basculement du fauteuil vers l’avant. Selon d'autres caractéristiques : le basculement rapproche du sol le support des pieds de l'utilisateur les roues avant sont plus grande que les roues arrière les roues avant sont motrices le fauteuil est muni d’une chenille escamotable qui peut être abaissée pour passer d’une position de repos dans laquelle elle ne touche pas le sol à une position de travail dans laquelle elle touche le sol et est entraînée par une roue avant la réduction de l'empattement provoque le remplacement de la roue arrière par une chenille le fauteuil comporte un mécanisme de leviers associé chacun a une roue libre entraînant les roues avant le mouvement dudit levier entraîne le mouvement du fauteuil vers l’avantDESCRIPTION OF THE INVENTION The invention is a wheelchair characterized by the fact that its wheelbase is adjustable and that the reduction of said wheelbase results in a tilting of the wheelchair forward. According to other characteristics: the tilting brings the support of the user's feet closer to the ground, the front wheels are larger than the rear wheels, the front wheels are driving, the wheelchair is equipped with a retractable track that can be lowered to a rest position in which it does not touch the ground to a working position in which it touches the ground and is driven by a wheel before the reduction of the wheelbase causes the replacement of the rear wheel by a caterpillar the wheelchair comprises a lever mechanism each associated with a free wheel driving the wheels before the movement of said lever causes the movement of the wheelchair forward
Description détaillée de l’inventionDetailed description of the invention
Le principe de la présente invention est de faire basculer le fauteuil vers l’avant lorsqu’on diminue son empattement. Après ce basculement, le support des pieds de futilisateur touche avantageusement le sol, ce qui facilite son embarquement et son débarquement.The principle of the present invention is to tilt the wheelchair forward when decreasing its wheelbase. After this tilting, the support of the user's feet advantageously touches the ground, which facilitates its boarding and disembarkation.
Le fauteuil roulant comporte avantageusement des roues motrices qui sont situées à l’avant et qui sont de grande tailles. La préhension d’une roue située à l’avant est plus ergonomique que celle d’une roue située à l’arrière du fauteuil.The wheelchair advantageously comprises driving wheels which are located at the front and which are large. The grip of a wheel at the front is more ergonomic than that of a wheel located at the back of the chair.
De grandes roues situées à l’avant ont aussi pour avantage de faciliter le franchissement d’obstacles.Large wheels at the front also have the advantage of facilitating the crossing of obstacles.
Les roues arrière peuvent être remplacées par une ou plusieurs chenilles. Il est également possible d’avoir des roues arrière qui ne » changent pas de position, et une chenille qui peut se déplacer pour s’abaisser en s’avançant, ce qui a pour effet de diminuer l’empattement du fauteuil tout en assurant son support à l’arrière par une ou plusieurs chenilles et non plus par les roues arrières (version non représentée).The rear wheels can be replaced by one or more tracks. It is also possible to have rear wheels that do not "change position, and a track that can move to lower itself while advancing, which has the effect of reducing the wheelbase of the chair while ensuring its support at the rear by one or more tracks and no longer by the rear wheels (not shown).
Une roue avant peut être munie d’une chenille escamotable qui peut être abaissée pour passer d’une position de repos dans laquelle elle ne touche pas le sol à une position de travail dans laquelle elle touche le sol et est entraînée par une roue avant (version non représentée). Avantageusement, le fauteuil comporte un mécanisme de leviers associé chacun a une roue libre entraînant les roues avant. Dans une version perfectionnée, le mouvement de ce levier d’avant en arrière entraîne le mouvement du fauteuil vers l’avant. Il est évidemment possible de munir cette transmission d’un variateur.A front wheel may be provided with a retractable track which can be lowered from a resting position in which it does not touch the ground to a working position in which it touches the ground and is driven by a front wheel ( version not shown). Advantageously, the chair comprises a lever mechanism each associated with a freewheel driving the front wheels. In an improved version, the movement of this lever from front to back causes the movement of the chair forward. It is obviously possible to provide this transmission with a variator.
Les roues motrices peuvent être motorisées, ainsi que les mécanismes assurant la modification de la géométrie du fauteuil roulant.The driving wheels can be motorized, as well as the mechanisms ensuring the modification of the geometry of the wheelchair.
Applications L'invention s’applique à tous fauteuils roulants motorisée ou non. Elle permet également de réaliser des véhicules urbains électriques particulièrement sécures, confortables et peu encombrants.Applications The invention applies to all motorized wheelchairs or not. It also makes electric urban vehicles particularly safe, comfortable and space-saving.
