Abstract

L'invention concerne principalement un mécanisme de pied qui se déplie afin de permettre la descente marche après marche à tout véhicule de transport de personne ou de marchandise. Il est composé d'un système de type pantographe, dont une glissière permet de définir le trajet d'un pied lors de son extension et de sa contraction, afin de s'adapter à la configuration désirée (diamètre des roues du fauteuil, hauteur/profondeur maximale des marches,...). En complément, un vérin amortisseur (ou contrôleur de vitesse) permet de réguler la vitesse de descente. Ce vérin amortisseur est doté d'une précharge ce qui lui permet de se repositionner en extension rapidement et sans résistance, permettant ainsi son déploiement à chaque marche sans intervention extérieure.The invention mainly relates to a foot mechanism which unfolds in order to allow the descent step by step to any vehicle for transporting people or goods. It is composed of a pantograph type system, a slide of which allows the path of a foot to be defined during its extension and contraction, in order to adapt to the desired configuration (diameter of the wheels of the chair, height / maximum depth of the steps, ...). In addition, a damping cylinder (or speed controller) can regulate the descent speed. This shock absorber cylinder has a preload which allows it to reposition itself in extension quickly and without resistance, thus allowing its deployment on each step without external intervention.

Description

DescriptionDescription

Titre de l’invention : Dispositif de descente de marches pour équipement de transport [0001] L’invention concerne un dispositif non motorisé permettant à un équipement de transport de personnes ou de marchandises de descendre des marches.Title of the invention: Device for descending steps for transport equipment The invention relates to a non-motorized device enabling equipment for transporting people or goods to descend from the steps.

[0002] Il n’est pas connu à l’heure actuelle de documents faisant référence à un tel dispositif permettant de descendre des escaliers.It is not known at the present time of documents referring to such a device making it possible to descend stairs.

[0003] Les solutions de l’art antérieur ne montrent pas de solution à cette problématique.The solutions of the prior art do not show a solution to this problem.

[0004] Un des objectifs de l’invention consiste à proposer une solution permettant de faciliter la descente d’obstacles, tels que des escaliers, à un charriot ou à un fauteuil roulant pour Personne à Mobilité Réduite.One of the objectives of the invention to provide a solution to facilitate the descent of obstacles, such as stairs, a cart or a wheelchair for people with reduced mobility.

[0005] Ainsi, l’invention concerne un mécanisme de descente qui est fixé sur un chariot ou un fauteuil roulant qui permet à ces derniers de descendre marche après marche en prenant appui sur la marche en aval et en dissipant l’énergie potentielle libérée lors de la descente.Thus, the invention relates to a descent mechanism which is fixed on a trolley or a wheelchair which allows the latter to descend step after step by resting on the step downstream and by dissipating the potential energy released during of the descent.

[0006] Selon l’invention, le système est conçu sur le principe de vérins amortisseurs fixés sur le chariot ou le fauteuil qui permettent d’amortir la descente.According to the invention, the system is designed on the principle of damping cylinders fixed on the carriage or the chair which make it possible to dampen the descent.

[0007] La solution de l’invention consiste en un unique système de vérins fixés sur le châssis de l’équipement.The solution of the invention consists of a single system of jacks fixed to the chassis of the equipment.

[0008] Un pied dont l’extrémité comporte une roulette est fixé sous le châssis du fauteuil et vient prendre appui sur la marche inférieure et ainsi réguler la vitesse de descente entre chaque marche.A foot whose end has a caster is fixed under the chassis of the chair and comes to rest on the bottom step and thus regulate the speed of descent between each step.

[0009] La cinématique du pied est pilotée par un système de type pantographe, dont une glissière permet de définir le trajet du pied lors de son extension et de sa contraction, afin de s’adapter à la configuration désirée (diamètre des roues du fauteuil, hauteur/ profondeur maximale des marches, ...).The kinematics of the foot is controlled by a pantograph type system, a slide of which makes it possible to define the path of the foot during its extension and its contraction, in order to adapt to the desired configuration (diameter of the wheels of the chair , maximum height / depth of steps, ...).

[0010] En complément du système de type pantographe décrit précédemment et servant à piloter le trajet du pied, un vérin amortisseur (ou contrôleur de vitesse) permet de réguler la vitesse de descente. Il n’intervient pas dans la cinématique, mais est dimensionné de façon à limiter la vitesse de descente à la valeur souhaitée pour l’emport maximal du fauteuil. Pour un emport plus faible, la vitesse sera proportionnellement plus basse. Ce vérin amortisseur est un vérin simple effet amortissant uniquement lors de la compression.In addition to the pantograph type system described above and used to control the path of the foot, a damping cylinder (or speed controller) can regulate the descent speed. It does not intervene in the kinematics, but is dimensioned so as to limit the speed of descent to the desired value for the maximum carrying of the wheelchair. For a lower lift, the speed will be proportionally lower. This damping cylinder is a single acting cylinder damping only during compression.

[0011] Il peut aussi se repositionner en extension de manière quasi-instantanée sans résistance, et déploie le système à chaque marche sans intervention extérieure. Un ressort de détente peut être positionné dans le système pour sécuriser le déploiement du vérin.It can also reposition itself in extension almost instantaneously without resistance, and deploys the system at each step without external intervention. A detent spring can be positioned in the system to secure the deployment of the jack.

[0012] [0013] [0014] [0015] [0016] [0017][0012] [0014] [0015] [0016] [0017]

L’invention concerne aussi tout dispositif de transport équipé avec au moins un système d’amortissement de descente tel que décrit précédemment.The invention also relates to any transport device equipped with at least one descent damping system as described above.

Selon différents modes de réalisation de l’invention, qui pourront être pris ensemble ou séparément :According to different embodiments of the invention, which can be taken together or separately:

- le dispositif de transport de l’invention comprend un fauteuil de transport d’une personne à mobilité réduite,- the transport device of the invention comprises a transport chair for a person with reduced mobility,

- le dispositif de transport de l’invention comprend un réceptacle destiné au transport d’objets divers,- the transport device of the invention comprises a receptacle intended for the transport of various objects,

- le dispositif de transport de l’invention est applicable à tout équipement de transport motorisé ou pas.- the transport device of the invention is applicable to any motorized or non-motorized transport equipment.

- La figure N°1 décrit les éléments constitutifs du système- Figure N ° 1 describes the constituent elements of the system

- Les figures N°2 à 9 décrivent le dispositif dans les positions qu’il adopte successivement lors du passage d’une marche à la suivante.- Figures N ° 2 to 9 describe the device in the positions it adopts successively when switching from one step to the next.

- La cinématique du pied est pilotée par un système de type pantographe, dont une glissière permet de définir le trajet du pied lors de son extension et de sa contraction, afin de s’adapter à la configuration désirée (diamètre des roues du fauteuil, hauteur/profondeur maximale des marches, ...).- The kinematics of the foot is controlled by a pantograph type system, a slide of which makes it possible to define the path of the foot during its extension and its contraction, in order to adapt to the desired configuration (diameter of the wheels of the chair, height / maximum depth of the steps, ...).

- En complément du système de type pantographe décrit précédemment et servant à piloter le trajet du pied, un vérin amortisseur (ou contrôleur de vitesse) permet de réguler la vitesse de descente. Il n’intervient pas dans la cinématique, mais est dimensionné de façon à limiter la vitesse de descente à la valeur souhaitée pour l’emport maximal du fauteuil. Pour un emport plus faible, la vitesse sera proportionnellement plus basse. Ce vérin amortisseur est un vérin simple effet amortissant uniquement lors de la compression. Il est également doté d’une précharge. Ainsi il se repositionne en extension de manière quasi-instantanée sans résistance, et déploie le système à chaque marche sans intervention extérieure.- In addition to the pantograph-type system described above and used to control the path of the foot, a damping cylinder (or speed controller) makes it possible to regulate the descent speed. It does not intervene in the kinematics, but is dimensioned so as to limit the speed of descent to the desired value for the maximum carrying of the wheelchair. For a lower lift, the speed will be proportionately lower. This damping cylinder is a single acting cylinder damping only during compression. It also has a preload. Thus it repositioned in extension almost instantaneously without resistance, and deploys the system on each step without external intervention.

- Le système de transport avance vers le premier nez de marche (figures N°3 et 4), où le pied pourra se déployer vers la marche suivante.- The transport system advances towards the first stair nosing (figures N ° 3 and 4), where the foot can be deployed towards the next step.

- Avant que le contact roues/sol n’atteigne le nez de marche, le pied se déploie (figures N°5 et 6).- Before the wheels / ground contact reaches the stair nosing, the foot is deployed (figures N ° 5 and 6).

- Lorsque le système de transport avance et commence à descendre vers la marche suivante, le pied avance également, mais oppose une force verticale tout en se repliant sous le châssis, ce qui régule la vitesse de descente (figures N°7 à 9).- When the transport system advances and begins to descend towards the next step, the foot also advances, but opposes a vertical force while folding under the chassis, which regulates the speed of descent (Figures N ° 7 to 9).

- Le système de transport avance vers le nez de marche suivant (figures N°3 et 4), où le pied pourra ensuite se déployer à nouveau vers la marche suivante, et ainsi de suite.- The transport system advances to the next step nosing (figures N ° 3 and 4), where the foot can then deploy again towards the next step, and so on.

[0018] Le dispositif prévoit un mécanisme de ressorts qui permettent au dispositif de rester au repos en position relevée (figure N°2). Un simple système de relâchement des pieds de descente est actionné par Γ utilisateur à sa demande.The device provides a spring mechanism which allows the device to remain at rest in the raised position (Figure No. 2). A simple system for releasing the lowering feet is activated by sa user at his request.
