Description

Dispositif pour déplacement de personne handicapée.Device for moving disabled people.

L'invention a pour objet un dispositif de déplacement pour personne invalide qui permet, même à une personne gravement.handicapée, de se déplacer et de retrouver une certaine autonomie dans un logement de construction courante pour personnes valides.The subject of the invention is a movement device for a disabled person which allows, even to a severely handicapped person, to move around and regain a certain autonomy in a housing of current construction for able-bodied people.

On connait déjà des fauteuils roulants de divers types, plus ou moins perfectionnés, qui peuvent être motorisés. Ces fauteuils sont nécessairement encombrants, lourds et coûteux. Leur largeur ne leur permet pas de passer dans les ouvertures des portes courantes. Leur poids ne permet pas de les emporter facilement d'un logement à un autre ; même quand ils sont pliants, leur encombrement reste important et nécessite un coffre de voiture automobile de grandes dimensions. Quand ils sont motorisés, leur maniement n'exige plus que très peu de force et de mobilité de la personne handicapée, mais ils sont encore plus lourds et plus coûteux.There are already known wheelchairs of various types, more or less sophisticated, which can be motorized. These chairs are necessarily bulky, heavy and expensive. Their width does not allow them to pass through the openings of standard doors. Their weight does not allow them to be easily taken from one accommodation to another; even when they are foldable, their bulk remains large and requires a large car trunk. When they are motorized, their handling only requires very little strength and mobility from the disabled person, but they are even heavier and more expensive.

Le but principal de l'invention est d'apporter un dispositif de déplacement pour personne invalide qui diffère des fauteuils roulants par un encombrement réduit permettant son passage par toute ouverture de porte de largeur courante, par un poids peu élevé autorisant, grâce à son faible encombrement, son transport dans le coffre de toute voiture, ce dispositif n'exigeant cependant qu'une faible énergie et qu'une faible amplitude d'un seul membre supérieur pour rendre possible tous déplacements voulus à l'intérieur d'un logement d'une personne handicapée.The main object of the invention is to provide a movement device for disabled person which differs from wheelchairs by a reduced size allowing its passage through any door opening of current width, by a low weight allowing, thanks to its low size, its transport in the trunk of any car, this device however requiring only a low energy and a low amplitude of a single upper member to make possible any desired movements inside a housing a disabled person.

Un but supplémentaire de l'invention est de parvenir à un dispositif tel que précisé ci-dessus avec lequel il soit possible de se mouvoir avec une grande précision sur les distances très petites, ce qui est souvent nécessaire dans un logement encombré.A further object of the invention is to achieve a device as specified above with which it is possible to move with great precision over very small distances, which is often necessary in a congested housing.

Un autre but supplémentaire de l'invention est d'apporter un dispositif du type ci-dessus qui soit capable, en plus, de produire un effet de rééducation de la partie inférieure des membres inférieurs pendant son utilisation par une personne handicapée se servant de ses membres supérieurs.Another additional object of the invention is to provide a device of the above type which is capable, in addition, of producing a reeducation effect on the part lower limbs during use by a disabled person using their upper limbs.

On atteint le but principal de l'invention avec un dispositif de déplacement comprenant un châssis à roues ayant au moins une roue motrice et une roue directrice dans lequel le châssis comprend des surfaces d'appui destinées à supporter les pieds d'un siège courant quelconque tel qu'une chaise, par exemple, ayant une assise pour recevoir la personne invalide ,; le châssis se termine en sens vertical à un niveau inférieur à celui de l'assise et il sert à supporter d'une part, un moyen d'entraînement ayant un organe de manoeuvre situé sur un côté de l'emplacement destiné à être occupé par le siège, d'autre part, un mécanisme de commande de la roue ou des roues directrices ayant un organe de direction situé sur un côté de l'emplacement destiné à être occupé par le siège.The main object of the invention is achieved with a displacement device comprising a wheeled chassis having at least one driving wheel and a steering wheel in which the chassis comprises bearing surfaces intended to support the feet of any common seat. such as a chair, for example, having a seat to receive the disabled person,; the frame ends in a vertical direction at a level lower than that of the seat and it serves to support on the one hand, a drive means having an operating member located on one side of the space intended to be occupied by the seat, on the other hand, a control mechanism for the wheel or steerable wheels having a steering member located on one side of the space intended to be occupied by the seat.

De préférence, le moyen d'entraînement comprend un arbre disposé en sens transversal du dispositif à un niveau inférieur à celui de l'assise du siège et ayant ses deux parties extrêmes accessibles respectivement d'un côté et de l'autre de l'emplacement réservé au siège. Chacune des parties extrêmes de l'arbre transversal est destinée à recevoir un volant amovible auquel on peut substituer, en variante, à volonté un levier à cliquet également amovible. Le mécanisme de commande des 4 roues directrices comprend un guidon situé à un niveau inférieur à celui de l'assise du siège et ayant une position neutre dans laquelle il est disposé en sens transversal du dispositif, ce guidon ayant à chacune de ses deux parties extrêmes opposées une allonge télescopique.Preferably, the drive means comprises a shaft arranged in the transverse direction of the device at a level lower than that of the seat cushion and having its two end parts accessible respectively from one side and the other from the location reserved for headquarters. Each of the end parts of the transverse shaft is intended to receive a removable flywheel which can be substituted, as a variant, at will, a ratchet lever also removable. The control mechanism of the 4 steering wheels comprises a handlebar located at a level lower than that of the seat cushion and having a neutral position in which it is arranged in the transverse direction of the device, this handlebar having at each of its two end parts opposite a telescopic extension.

Dans un mode de réalisation de l'invention, le châssis comprend deux flasques dressés parallèles, espacés en sens transversal du dispositif et les surfaces d'appui sont disposées à l'extérieur de ces deux flasques. Chaque flasque comprend deux tôles espacées et une roue non directrice est placée entre les deux tôles de chaque flasque, l'une au moins de ces roues étant entourée d'une courroie de préférence de type crantée qui s'étend jusqu'à une poulie calée sur un arbre transversal sur lequel se trouve au moins un organe de manoeuvre, la courroie passant autour de la surface de roulement de la roue en question.In one embodiment of the invention, the chassis comprises two parallel upright flanges, spaced in transverse direction of the device and the bearing surfaces are arranged outside these two flanges. Each flange comprises two spaced sheets and a non-steering wheel is placed between the two sheets of each flange, at least one of these wheels being surrounded by a belt, preferably of the notched type, which extends to a pulley wedged on a transverse shaft on which there is at least one drive member, the belt passing around the rolling surface of the wheel in question.

De préférence aussi, le châssis est équipé de deux repose-pieds montés avec une possibilité de déplacement entre une première position dans laquelle ils reposent sur le sol et une seconde position dans laquelle ils sont surélevés au-dessus du sol.Also preferably, the chassis is equipped with two footrests mounted with a possibility of displacement between a first position in which they rest on the ground and a second position in which they are raised above the ground.

Selon un mode préféré de réalisation de l'invention, les repose-pieds ont un prolongement et sont réunis par le prolongement à une barre transversale supportée par le châssis et pivotante entre une position avancée mettant les repose-pieds à leur première position et une position reculée mettant les repose-pieds à leur seconde position. En outre, la roue motrice est calée en rotation sur un "11 arbre transversal sur lequel sont montées deux cames à moyen d'embrayage et de débrayage en correspondance chacune respectivement avec un prolongement d'un repose-pieds, chaque prolongement étant espacé de la came correspondante quand le repose-pieds occupe sa première position et étant en contact avec cette même came quand le repose-pieds occupe sa seconde position et que les cames sont rendues actives par le moyen d'embrayage.According to a preferred embodiment of the invention, the footrests have an extension and are joined by the extension to a transverse bar supported by the frame and pivoting between an advanced position putting the footrests in their first position and a position moved back putting the footrests in their second position. In addition, the drive wheel is fixed in rotation on a "11 transverse shaft on which are mounted two cams by means of clutch and disengage in correspondence each respectively with an extension of a footrest, each extension being spaced from the corresponding cam when the footrest occupies its first position and being in contact with this same cam when the footrest occupies its second position and the cams are made active by the clutch means.

On donnera maintenant, sans intention limitative, et sans exclure aucune variante, une description d'un mode préféré de réalisation de l'invention. On se reportera aux dessins annexés dans lesquels :

  • La figure 1 est une vue générale en perspective de l'avant d'un dispositif selon l'invention, avec les repose-pieds en position de déplacement,
  • - la figure 2 est une vue analogue à la figure 1 mais le dispositif supportant une chaise pour une personne désirant l'utiliser pour se déplacer ,
  • - la figure 3 est une vue en perspective de l'arrière du dispositif de la figure 1,
  • - la figure 4 est une vue de dessous du même dispositif.
A description will now be given, without limiting intention, and without excluding any variant, of a preferred embodiment of the invention. Reference is made to the appended drawings in which:
  • FIG. 1 is a general perspective view of the front of a device according to the invention, with the footrests in the displacement position,
  • FIG. 2 is a view similar to FIG. 1 but the device supporting a chair for a person wishing to use it to move around,
  • FIG. 3 is a perspective view of the rear of the device in FIG. 1,
  • - Figure 4 is a bottom view of the same device.

Un dispositif conforme à l'invention comprend essentiellement un châssis 1 monté sur roues comprenant de préférence deux roues directrices 2 - qui sont les roues arrière dans cet exemple -et deux roues non directrices 3, 4 dont une seule, la roue 3, est une roue motrice. Ce châssis 1 comprend des surfaces d'appui 5 destinées à supporter les quatre pieds d'un siège tel qu'une chaise 6 représentée en trait plus fin sur la figure 2 seulement.A device according to the invention essentially comprises a chassis 1 mounted on wheels preferably comprising two steered wheels 2 - which are the rear wheels in this example - and two non-steered wheels 3, 4 of which only one, the wheel 3, is a Driving wheel. This frame 1 includes bearing surfaces 5 intended to support the four legs of a seat such as a chair 6 shown in a finer line in FIG. 2 only.

Les surfaces d'appui 5 se trouvent aussi près que possible du sol sur lequel roulent les roues 2 à 4 ; elles peuvent être disposées et dimensionnées pour convenir à un seul type de siège 6 mais il est préférable dans l'esprit de l'invention, de prévoir des surfaces d'appui 5 capables de recevoir indifféremment plusieurs types de siège 6. Il s'agit cependant de sièges d'usage courant quelconque dont la largeur est telle qu'ils passent sans difficulté par les ouvertures des portes courantes à l'intérieur des logements. Le châssis 1 est à peine plus large que le siège 6. Il peut être souhaitable, pour une meilleure stabilité, que certaines surfaces d'appui 5, celles de l'arrière dans l'exemple décrit ici, soient entourées d'une bordure qui s'oppose au glissement du pied correspondant.The bearing surfaces 5 are as close as possible to the ground on which the wheels 2 to 4 roll; they can be arranged and dimensioned to suit a single type of seat 6 but it is preferable in the spirit of the invention, to provide bearing surfaces 5 capable of indifferently receiving several types of seat 6. This is however, seats of any common use whose width is such that they pass without difficulty through the openings of current doors inside the accommodation. The frame 1 is hardly wider than the seat 6. It may be desirable, for better stability, that certain bearing surfaces 5, those of the rear in the example described here, are surrounded by a border which opposes the sliding of the corresponding foot.

Le siège 6 a une assise 8. Dans le sens de la hauteur à partir du sol, le châssis 1 se termine à un niveau inférieur à celui de l'assise 8, de sorte qu'il se trouve en-dessous de celle-ci.The seat 6 has a seat 8. In the height direction from the ground, the frame 1 ends at a level lower than that of the seat 8, so that it is below the latter. .

Le châssis 1 sert à supporter un moyen d'entraîne--ment de la roue motrice 3 ; ce moyen comprend un arbre 9 s'étendant en sens transversal au dispositif et situé près du sommet de ce dernier, à une faible distance en-dessous de l'assise 8. Sur chacun des côtés de l'emplacement destiné à cette dernière, l'arbre 9 présente une partie extrême libre réservée à un organe de manoeuvre. Chaque partie extrême est prévue pour recevoir un volant 10 ou pour recevoir un levier à cliquet 11. L'un ou l'autre de ces organes de manoeuvre 10, 11 peut être utilisé pour mouvoir le dispositif, en fonction de la validité de l'un ou l'autre membre supérieur de la personne assise sur le siège 8 et en fonction du genre de mouvement (rotation de volant ou mouvementsalternatifs du levier à cliquet 11) qu'elle préfère exécuter. Les deux organes de manoeuvre sont amovibles, interchangeables d'un côté et de l'autre du dispositif.The chassis 1 serves to support a drive means for the driving wheel 3; this means includes a tree 9 extending transverse to the device and located near the top of the latter, a short distance below the seat 8. On each side of the space intended for the latter, the shaft 9 has a part extreme free reserved for an operating device. Each end part is designed to receive a steering wheel 10 or to receive a ratchet lever 11. Either of these operating elements 10, 11 can be used to move the device, depending on the validity of the one or the other upper limb of the person sitting on the seat 8 and according to the kind of movement (rotation of the steering wheel or alternative movements of the ratchet lever 11) which he prefers to execute. The two operating members are removable, interchangeable on one side and on the other of the device.

Le châssis 1 sert encore à supporter un mécanisme de commande des roues directrices 2. Ce mécanisme comprend un guidon 12 qui a une position neutre de déplacement en ligne droite du dispositif dans laquelle il est disposé en sens transversal à ce dernier. A Chacune de ses extrémités opposées, le guidon 12 est pourvu d'une allonge télescopique 13 qui peut être escamotée comme sur la partie gauche de la figure 3 ou qui peut être étendue comme sur la partie droite de la même figure 3. Chaque allonge 13 est un organe de direction qui peut être rendu accessible sur l'un ou l'autre côté de l'emplacement destiné à l'assise 8 du siège 6, en fonction de la mobilité de l'un ou l'autre membre supérieur de la personne handicapée. Chaque allonge 13 peut être étendue sur le côté et escamotée quand il le faut, pour passer dans l'ouverture d'une porte ou pour la manoeuvre du volant 10 ou du levier 11.The chassis 1 also serves to support a control mechanism for the steered wheels 2. This mechanism includes a handlebar 12 which has a neutral position for displacement in a straight line of the device in which it is arranged in a direction transverse to the latter. At each of its opposite ends, the handlebar 12 is provided with a telescopic extension 13 which can be retracted as on the left part of FIG. 3 or which can be extended as on the right part of the same FIG. 3. Each extension 13 is a steering device which can be made accessible on either side of the space intended for the seat 8 of the seat 6, depending on the mobility of one or the other upper member of the disabled person. Each extension 13 can be extended on the side and retracted when necessary, to pass through the opening of a door or for the operation of the steering wheel 10 or of the lever 11.

La liaison entre le guidon 12 et les roues directrices 2 se fait de manière connue en soi à l'aide d'une tige verticale 14 (figure 4) munie d'un bras de commande 15 articulé par l'intermédiaire d'un bras auxiliaire 16 avec.un parallélogramme articulé 17 avec lequel les roues 2 sont accouplées pour leur orientation.The connection between the handlebars 12 and the steered wheels 2 is made in a manner known per se using a vertical rod 14 (FIG. 4) provided with a control arm 15 articulated by means of an auxiliary arm 16 with an articulated parallelogram 17 with which the wheels 2 are coupled for their orientation.

La liaison entre la roue motrice 3 et l'arbre transversal 9 se fait de façon connue en soi à l'aide de poulies et d'une courroie. Toutefois, dans le mode préféré de réalisation décrit ici, le châssis 1 comprend deux flasques parallèles espacés 18, 19 qui sont eux-mêmes composés chacun de deux tôles 18A, 18B et 19A, 19B, parallèles, tenues espacées par des entretoises. Les surfaces d'appui 5 sont justes en dehors de la largeur définie par la distance qui sépare les tôles extérieures 18A, 19A.The connection between the drive wheel 3 and the transverse shaft 9 takes place in a manner known per se using pulleys and a belt. However, in the preferred embodiment described here, the chassis 1 comprises two spaced parallel flanges 18, 19 which are themselves each composed of two parallel sheets 18A, 18B and 19A, 19B, held spaced apart by spacers. The bearing surfaces 5 are just outside the width defined by the distance which separates the outer sheets 18A, 19A.

'Dans chaque flasque 18, 19, les tôles 18A, 18B et 19A, 19B sont espacées de la distance nécessaire à la mise en place entre elles des roues non directrices 3, 4. Ces roues 3, 4 sont calées sur un arbre transversal 20 et la roue motrice 3 est entourée par une courroie 21 qui s'étend entre les deux tôles 18A, 18B du flasque 18 jusqu'à une poulie 22 calée sur l'arbre 9. De préférence, la roue 3, la poulie 22 et la courroie 21 sont crantées. On remarquera que la courroie 21 passe autour de la surface de roulement de la roue 3 de sorte qu'elle est serrée entre celle-ci et le sol, sous le poids du dispositif, de la chaise et de la personne assise sur cette dernière. On dispose d'un entraînement du type à cheville avec lequel tout effet de patinage est pratiquement supprimé. Grâce aux crans de la courroie 21, le plus léger mouvement de l'organe de manoeuvre 10., 11 provoque un déplacement correspondant du dispositif.Celui- ci est donc manoeuvrable avec une grande précision.'In each flange 18, 19, the sheets 18A, 18B and 19A, 19B are spaced by the distance necessary for the establishment between them of non-steerable wheels 3, 4. These wheels 3, 4 are wedged on a transverse shaft 20 and the drive wheel 3 is surrounded by a belt 21 which extends between the two sheets 18A, 18B of the flange 18 up to a pulley 22 wedged on the shaft 9. Preferably, the wheel 3, the pulley 22 and the belt 21 are notched. It will be noted that the belt 21 passes around the rolling surface of the wheel 3 so that it is clamped between the latter and the ground, under the weight of the device, the chair and the person seated on the latter. There is an ankle type drive with which any slip effect is practically eliminated. Thanks to the notches of the belt 21, the slightest movement of the operating member 10., 11 causes a corresponding movement of the device. It is therefore maneuverable with great precision.

Le dispositif décrit jusqu'à présent pourrait être utilisé à condition que les membres inférieurs de la personne assise sur le siège 6 restent pendants en avant de ce dernier.The device described so far could be used provided that the lower limbs of the person sitting on the seat 6 remain hanging in front of the latter.

Pour des personnes handicapées, il est souvent préférable de prévoir des repose-pieds 23 supportés par le bâti 1 entre les flasques 18, 19, en avant de l'emplacement destiné à recevoir le siège 6.For disabled people, it is often preferable to provide footrests 23 supported by the frame 1 between the flanges 18, 19, in front of the location intended to receive the seat 6.

De préférence, chaque repose-pied 23 a un prolongement 24 incliné vers l'arrière à un angle de 30° environ avec le sol et s'étendant entre les flasques 18, 19 jusqu'à une barre transversale mobile 25. Cette dernière est pivotante entre les flasques 18, 19 entre une position avancée et une position reculée à laquelle elle est représentée sur la figure 1 et à laquelle les repose-pieds 23 occupent une position surélevée au-dessus du sol. Cette position surélevée assure une garde au sol suffisante au déplacement par exemple pour passer au-dessusd'untapis ou d'un seuil en bordure d'une moquette. Cette position est appelée la seconde'position, la première position étant celle dans laquelle les repose-pieds 27 reposent sur le sol par leur face inférieure, quand la barre transversale mobile 25 a été mise à sa position avancée. Cette barre mobile 25 est pivotante dans cet exemple parce qu'elle constitue le côté inférieur d'un cadre dont le côté supérieur 26 est supporté et articulé entre les deux flasques 18, 19. A ce côté supérieur 26 est fixé un levier 27 qui s'étend vers l'arrière et qui est accessible en arrière et en dessous de l'assise 8 du siège 6 (figure 2). Ce levier 27 passe le long d'un tube vertical 28 qui contient et qui guide la tige verticale 14 à laquelle est fixé le guidon 12. Des moyens d'accrochage (non visibles sur les dessins) sont prévus pour l'accrochage du levier 27 au.tube 28 en correspondance avec la position avancée et avec la position reculée de la barre transversale mobile 25.Preferably, each footrest 23 has an extension ment 24 inclined rearward at an angle of approximately 30 ° with the ground and extending between the flanges 18, 19 to a movable transverse bar 25. The latter is pivotable between the flanges 18, 19 between an advanced position and a retracted position at which it is shown in Figure 1 and at which the footrests 23 occupy an elevated position above the ground. This raised position provides sufficient ground clearance for movement, for example to pass over a carpet or a threshold at the edge of a carpet. This position is called the second position, the first position being that in which the footrests 27 rest on the ground by their underside, when the movable crossbar 25 has been brought to its advanced position. This movable bar 25 is pivotable in this example because it constitutes the lower side of a frame whose upper side 26 is supported and articulated between the two flanges 18, 19. To this upper side 26 is fixed a lever 27 which s 'extends rearward and which is accessible behind and below the seat 8 of the seat 6 (Figure 2). This lever 27 passes along a vertical tube 28 which contains and guides the vertical rod 14 to which the handlebar is fixed 12. Hooking means (not visible in the drawings) are provided for hooking the lever 27 au.tube 28 in correspondence with the advanced position and with the retracted position of the movable crossbar 25.

Les prolongements 24 sont réunis à la barre transversale mobile 25 par leur extrémité supérieure. Au voisinage de leur extrémité inférieure par laquelle ils sont réunis aux repose-pieds 23, il existe entre les flasques 18, 19 une barre de soutien transversale 29, fixe, sur laquelle les prolongements 24 reposent et glissent librement. Cette barre de soutien fixe 29 a pour effet que lorsque la barre transversale mobile 25 est mise à sa position avancée, les prolongements 24 se déplacent vers l'avant et basculent légèrement autour de cette barre de soutien fixe 29. Les repose-pieds 23 viennent au contact du sol au moins par leurs bords extrêmes, ce qui fait qu'une personne handicapée qui marche en trainant ou en faisant glisser ses pieds sur le sol , peut néanmoins monter sur les repose-pieds 23 sans avoir à soulever réellement ses pieds et sans risquer d'être déséquilibrée en se tenant sur une seule jambe. Quand cette personne s'est assise sur le siège 6 après s'être retournée en position debout sur les repose-pieds 23, une autre personne manoeuvre le levier 27 et l'accroche au tube vertical 28 en position de soulèvement des repose-pieds 23.The extensions 24 are joined to the movable crossbar 25 by their upper end. In the vicinity of their lower end by which they are joined to the footrests 23, there is between the flanges 18, 19 a transverse support bar 29, fixed, on which the extensions 24 rest and slide freely. This fixed support bar 29 has the effect that when the movable crossbar 25 is put in its advanced position, the extensions 24 move forward and tilt slightly around this fixed support bar 29. The footrests 23 come into contact with the ground at least by their extreme edges, so that a disabled person who walks by dragging or sliding his feet on the ground can nevertheless climb on the footrests 23 without having to actually lift his feet and without risking being unbalanced by standing on one leg. When this person sits on the seat 6 after having turned over in a standing position on the footrests 23, another person operates the lever 27 and hooks it to the vertical tube 28 in the lifting position of the footrests 23 .

L'arbre 20 qui porte les roues 3, 4 passe en dessous des prolongements 24, à une position plus élevée et plus en arrière que celle de la barre de soutien fixe 29. De ce fait, quand la barre transversale mobile 25 est mise à sa position avancée, les prolongements 24 sont plus éloignés de cet arbre 20 puisqu'ils ont été avancés et qu'ils ont basculé vers l'avant autour de la barre de soutien fixe 29.The shaft 20 which carries the wheels 3, 4 passes below the extensions 24, to a higher position and further back than that of the fixed support bar 29. Therefore, when the movable transverse bar 25 is brought to in its advanced position, the extensions 24 are more distant from this shaft 20 since they have been advanced and they have tilted forward around the fixed support bar 29.

L'arbre 20 porte un fourreau 30 coulissant en sens axial qui porte lui-même deux cames 31 à excentration qui correspondent chacune respectivement à un prolongement 24. Ces cames 31 peuvent être embrayées ou débrayées par rapport à l'arbre 20 grâce à un moyen de crabotage 32 prévu entre cet arbre 20 et le fourreau 30 qui peut être rendu actif ou inactif selon la position en sens axial du fourreau 30. Sur la figure 4, le moyen de crabotage 32 est inactif.The shaft 20 carries an axially sliding sleeve 30 which itself carries two eccentric cams 31 which each correspond respectively to an extension 24. These cams 31 can be engaged or disengaged relative to the shaft 20 by means clutch 32 provided between this shaft 20 and the sleeve 30 which can be made active or inactive depending on the position in the axial direction of the sleeve 30. In Figure 4, the clutch means 32 is inactive.

Chaque prolongement 24 est pourvu sur sa face inférieure d'une nervure de renforcement longitudinale 33 avec- laquelle la surface de la came 31 correspondante peut coopérer quand le fourreau 30 a été déplacé pour rendre actif le moyen de crabotage 32. Ce déplacement axial du fourreau 30 et des cames 31 jusqu'à mettre celles-ci en-dessous des nervures 33 est possible quand la barre transversale mobile 25 a été mise à sa position avancée et que les repose-pieds 23 touchent le sol. Ainsi, quand la personne s'est assise sur le siège 6 et que la barre transversale mobile 25 a été remise à sa position reculée à l'aide du levier 27, les prolongements 24 viennent reposer par leurs nervures de renforcement 33 sur les cames 31, si bien qu'ils sont soulevés au-dessus de la barre de soutien fixe 29. Pendant le déplacement du dispositif, l'arbre 20 fait tourner le fourreau 30 et les cames 31 à excentration. Les prolongements 24 et les repose-pieds 23 sont alors soulevée et abaissés de l'amplitude déterminée par le profil des cames 31 de manière'continue répétée. A cet effet, la barre transversale mobile 25 est réunie par un axe aux petits côtés du cadre dont elle fait partie. Les cames 31 peuvent être du type à excentration réglable.Each extension 24 is provided on its underside with a longitudinal reinforcing rib 33 with which the surface of the corresponding cam 31 can cooperate when the sleeve 30 has been moved to make the dog clutch means 32 active. This axial movement of the sleeve 30 and cams 31 until they are placed below the ribs 33 is possible when the movable crossbar 25 has been put in its advanced position and the footrests 23 touch the ground. Thus, when the person sits on the seat 6 and the movable crossbar 25 has been returned to its retracted position using the lever 27, the extensions 24 come to rest by their reinforcing ribs 33 on the cams 31 , so that they are raised above the fixed support bar 29. During the movement of the device, the shaft 20 rotates the sleeve 30 and the cams 31 eccentrically. The extensions 24 and the footrests 23 are then raised and lowered by the amplitude determined by the profile of the cams 31 repeatedly. To this end, the movable crossbar 25 is joined by an axis to the short sides of the frame of which it is a part. The cams 31 may be of the type with adjustable offset.

L'amplitude des mouvements de soulèvement et d'abaissement successifs imposés aux pieds est faible mais elle est utile dans de nombreuses circonstances contre l'ankylose ou au début d'exercices de rééducation.The amplitude of the successive movements of lifting and lowering imposed on the feet is small but it is useful in many circumstances against ankylosis or at the beginning of rehabilitation exercises.
