Description

La présente invention a pour objet un dispositif d'assistance aidant une personne à sortir d'une baignoire. Son utilisation est particulièrement recommandée pour des personnes âgées ou handicapées et notamment pour des personnes seules qui, dans la pratique, ne peuvent prendre un bain sans s'exposer à une chute ayant souvent des conséquences désastreuses au moment où la personne veut sortir de la baignoire.The present invention relates to an assistance device helping a person to get out of a bathtub. Its use is particularly recommended for elderly or disabled people and in particular for single people who, in practice, cannot take a bath without being exposed to a fall often having disastrous consequences when the person wants to get out of the bathtub. .

Pour faciliter la sortie de la baignoire, on prévoit parfois une poignée fixée à mi-hauteur d'homme sur le mur qui longe le grand côté de la baignoire, ou bien encore deux accoudoirs sur les faces internes de la baignoire. Ces dispositifs constituent déjà une assistance appréciable pour une personne n'ayant plus des capacités sportives développées et lui permettant de se redresser plus facilement dans un milieu glissant.To make it easier to get out of the bathtub, there is sometimes a handle fixed halfway up on the wall that runs along the long side of the bathtub, or even two armrests on the internal sides of the bathtub. These devices already constitute appreciable assistance for a person no longer having developed sports capacities and allowing him to straighten up more easily in a slippery environment.

Le savon, les huiles et mousses pour bains, l'eau adoucie augmentent encore les difficultés. Les statistiques montrent qu'en fait, un très grand nombre de personnes, surtout âgées et handicapées, sont victimes de chutes graves à la sortie de leur baignoire.Soap, bath oils and foams, softened water add to the difficulties. Statistics show that in fact, a very large number of people, especially the elderly and the disabled, fall victim to serious falls from their baths.

On sait que pour aider une personne en difficulté, on lui prend la main, et on tire à soi. Le dispositif d'assistance objet de la présente invention répond à ce principe et permet à une personne âgée ou handicapée de sortir seule de sa baignoire, sans danger, au moment où elle le désire. En outre, le dispositif objet de l'invention est de construction simple, fiable et peut s'adapter à n'importe quelle baignoire à faible prix. Eventuellement, la baignoire peut être spécialement prévue et équipée pour recevoir un tel dispositif d'assistance.We know that to help a person in difficulty, we take their hand and we shoot at ourselves. The assistance device object of the present invention meets this principle and allows an elderly or disabled person to get out of the bath alone, without danger, when they want. In addition, the device object of the invention is simple, reliable and can adapt to any bathtub at low cost. Optionally, the bathtub can be specially provided and equipped to receive such an assistance device.

On connaît des dispositifs à vérins hydrauliques suspendus facilitant la levée d'une personne installée dans une baignoire, tel par exemple que décrit dans le document DE-A-2 738 310. Ces dispositifs sont cependant très encombrants nécessitant un aménagement important de la salle d'eau, et leur emploi est relativement difficile, limité en fait au domaine hospitalier en vue de faciliter le travail et réduire les efforts du personnel soignant, car ils nécessitent une commande séparée pour le fonctionnement du vérin.There are known devices with suspended hydraulic cylinders facilitating the lifting of a person installed in a bathtub, such as for example that described in document DE-A-2 738 310. These devices are however very bulky requiring significant fitting out of the bathroom. water, and their use is relatively difficult, limited in fact to the hospital field in order to facilitate the work and reduce the efforts of the nursing staff, because they require a separate control for the operation of the jack.

On connaît également selon le document NL-A 7 603 243 un dispositif à levier articulé permettant une mise à l'eau dans une piscine d'une personne handicapée. Ce dispositif n'est cependant pas adapté à un usage domestique pour une salle de bain, et nécessite là encore la présence et l'assistance d'une personne commandant le mouvement du dispositif.Also known from document NL-A 7,603,243 is an articulated lever device allowing a disabled person to be put into the water in a swimming pool. This device is however not suitable for domestic use in a bathroom, and again requires the presence and assistance of a person controlling the movement of the device.

Contrairement aux dispositifs connus, le dispositif objet de l'invention est d'encombrement très réduit, d'usage très simple et trouve normalement sa place dans n'importe quelle salle d'eau individuelle. Il pourra être également utilisé pour assister la personne a entrer dans une baignoire, et tout aussi bien, à se lever d'un lit ou à s'y coucher, à se lever d'un siège ou s'y asseoir, en particulier pour l'usage d'un siège de double WC.Unlike the known devices, the device which is the subject of the invention is very compact, of very simple use and normally finds its place in any individual bathroom. It can also be used to assist the person to enter a bathtub, and just as well, to get up from a bed or to lie down, to get up from a seat or to sit there, in particular for the use of a double WC seat.

Le dispositif de l'invention est du type comprenant essentiellement un vérin susceptible d'être alimenté en pression par l'eau d'alimentation de la baignoire, des moyens de préhension tels qu'une poignée ou un harnais et des moyens pour commander à partir dudit vérin le soulèvement et l'abaissement automatiques desdits moyens de préhension, le dispositif se caractérise en ce que ladite poignée ou le harnais est monté à l'extrémité d'un levier articulé vers son autre extrémité autour d'un axe et la rotation du levier est commandée par ledit vérin, et en ce que l'alimentation et la mise sous pression du vérin sont commandées à partir de moyens à soupape qui sont actionnés directement par un effort de préhension appliqué sur ladite poignée ou sur ledit harnais.The device of the invention is of the type essentially comprising a jack capable of being supplied with pressure by the water supplying the bath, gripping means such as a handle or a harness and means for controlling from said jack the automatic raising and lowering of said gripping means, the device is characterized in that said handle or the harness is mounted at the end of a lever articulated towards its other end around an axis and the rotation of the lever is controlled by said cylinder, and in that the supply and the pressurization of the cylinder are controlled from valve means which are actuated directly by a gripping force applied to said handle or to said harness.

On comprend qu'un tel dispositif est de fonctionnement très sûr et peut être installé très facilement sur une baignoire qui est automatiquement alimentée en eau sous des débits et des pressions parfaitement compatibles avec un bon fonctionnement du vérin pour l'usage recherché.We understand that such a device is very safe to operate and can be installed very easily on a bathtub which is automatically supplied with water at flow rates and pressures perfectly compatible with proper operation of the actuator for the intended use.

L'alimentation et la mise sous pression du vérin étant commandées à partir de la poignée ou dudit harnais du dispositif, dès que la personne se saisit convenablement de la poignée ou du harnais, le dispositif se met automatiquement en actionnement, assistant efficacement la personne qui veut se redresser et sortir de sa baignoire.The supply and the pressurization of the jack being controlled from the handle or said harness of the device, as soon as the person appropriately grasps the handle or the harness, the device is automatically actuated, effectively assisting the person who wants to sit up and get out of the tub.

Selon un deuxième mode de réalisation, la poignée ou le harnais est monté à l'extrémité d'un levier dont l'autre extrémité est solidaire de l'axe de rotation d'un second levier commandé en rotation en étant articulé à une certaine distance dudit axe à une première extrémité dudit vérin dont l'autre extrémité est articulée en un point fixe. De cette façon, le dispositif peut être facilement escamoté en position de non-utilisation, dégageant entièrement l'usage de l'appareil : baignoire, siège de WC ou lit auquel il facilite l'accès.According to a second embodiment, the handle or the harness is mounted at the end of a lever whose other end is integral with the axis of rotation of a second lever controlled in rotation by being articulated at a certain distance from said axis to a first end of said cylinder whose other end is articulated at a fixed point. In this way, the device can be easily retracted into the non-use position, completely freeing the use of the device: bath, toilet seat or bed to which it facilitates access.

Selon une autre caractéristique des perfectionnements de l'invention, ledit vérin et ledit second levier sont articulés respectivement autour desdits axes fixes sur une platine de support et de fixation de l'ensemble du dispositif. De cette manière, le dispositif peut être facilement fixé à une paroi, telle qu'un mur, adjacente à l'appareil auquel il facilite l'accès. La pose et d'adaptation du dispositif en sont grandement facilitées, l'appareil pouvant être intégré voire encastré sur ou dans la paroi à laquelle il est fixé.According to another characteristic of the improvements of the invention, said cylinder and said second lever are articulated respectively around said fixed axes on a support and fixing plate of the whole device. In this way, the device can be easily attached to a wall, such as a wall, adjacent to the device to which it facilitates access. The installation and adaptation of the device are greatly facilitated, the device being able to be integrated or even embedded on or in the wall to which it is fixed.

En se référant tout d'abord à la figure 1, on a montré une personne 1 qui s'est mise en position assise, buste redressé, dans sa baignoire 2. Le dispositif d'assistance conforme à l'invention repéré dans son ensemble 3 est fixé, dans le mode de mise en oeuvre illustré, sur le mur 4 contre lequel est appuyée l'extrémité de pied de la baignoire 2. Le dispositif 3 se compose essentiellement, comme il apparaît plus clairement à la figure 2, d'un châssis 5 à deux branches verticales 6, 7 qui sont fixées au mur 4 par des vis 8 et comportant deux branches horizontales 9, 10, d'un vérin 11 et d'un cadre mobile 12 comportant une poignée 13. Le cadre mobile 12 est articulé autour d'un axe 14 dans, deux paliers 15, 16 formés vers les extrémités des branches 6, 7. Le vérin 11 est articulé à une de ses extrémités en 17 sur un axe 18 fixé aux extrémités des bras 9,10 du châssis 5. A son autre extrémité, le vérin est articulé en 19 sur une barre transversale 20 du cadre articulé 12.Referring firstly to FIG. 1, a person 1 has been shown who has taken up a sitting position, upright bust, in his bathtub 2. The assistance device according to the invention identified as a whole 3 is fixed, in the illustrated embodiment, on the wall 4 against which the end of the foot of the bathtub 2 is supported. The device 3 essentially consists, as it appears more clearly in FIG. 2, of a chassis 5 with two vertical branches 6, 7 which are fixed to the wall 4 by screws 8 and comprising two horizontal branches 9, 10, a jack 11 and a movable frame 12 comprising a handle 13. The movable frame 12 is articulated around an axis 14 in, two bearings 15, 16 formed towards the ends of the branches 6, 7. The jack 11 is articulated at one of its ends at 17 on an axis 18 fixed to the ends of the arms 9, 10 of the chassis 5. At its other end, the jack is articulated at 19 on a transverse bar 20 of the articulated frame 12.

Le vérin 11 peut être alimenté en eau à partir d'un tuyau souple 21 branché sur l'alimentation en eau 22 de la baignoire, par exemple sur la dérivation d'alimentation de la douche 23. Dans le mode de réalisation illustré schématiquement à la figure 2, une manette 24 peut occuper trois positions, soit d'alimentation du robinet de la baignoire, soit d'alimentation de la douche, soit d'alimentation du tuyau souple 21. Dans une réalisation plus simple, la douche peut être omise et la manette 24 pourra occuper seulement deux positions, soit d'alimentation du vérin.The jack 11 can be supplied with water from a flexible pipe 21 connected to the water supply 22 of the bath, for example on the supply branch of the shower 23. In the embodiment illustrated schematically in the FIG. 2, a handle 24 can occupy three positions, either for supplying the bathtub tap, or for supplying the shower, or for supplying the flexible hose 21. In a simpler embodiment, the shower can be omitted and the lever 24 can occupy only two positions, that is to say supplying the jack.

Enfin, le dispositif est complété par un clapet ou une soupape 25 formé à la base du vérin 11 et permettant sa vidange.Finally, the device is completed by a flap or a valve 25 formed at the base of the jack 11 and allowing its emptying.

Le fonctionnement du dispositif décrit va être maintenant expliqué.The operation of the device described will now be explained.

La personne étant dans son bain et désirant en sortir se met en position assise, comme illustré en 1 en trait plein à la figure 1.The person being in his bath and wishing to get out of it goes into a sitting position, as illustrated in 1 in solid lines in FIG. 1.

Si la poignée 13 du dispositif est soulevée, par exemple dans la position 13' illustrée en traits interrompus, par suite de l'extension du vérin, la personne procède tout d'abord à la vidange ou purge du vérin 11 en actionnant la soupape de vidange 25. Le vérin se vide dans la baignoire et le cadre mobile s'abaisse pour venir occuper la position basse illustrée en trait plein en 12 à la figure 1. Dans cette position, la personne peut se saisir aisément de la poignée 13.If the handle 13 of the device is raised, for example in the position 13 ′ illustrated in dashed lines, as a result of the extension of the jack, the person first of all empties or bleeds the jack 11 by actuating the valve emptying 25. The jack is emptied into the bathtub and the movable frame is lowered to occupy the low position illustrated in solid lines at 12 in FIG. 1. In this position, the person can easily take hold of the handle 13.

Dans cette position, la personne procède alors à la mise en eau sous pression du vérin, en prenant soin de placer la manette 24 dans la position d'alimentation du vérin et d'ouvrir le robinet par exemple d'alimentation d'eau froide 26 de la baignoire. Avantageusement, la mise en eau du vérin 11 ne s'effectue, à la demande de la personne, que lorsqu'elle s'appuie suffisamment sur la poignée 13 par exemple, au moyen d'un dispositif tel que celui qui sera décrit plus loin en relation aux figures 3 et 4. Une telle ouverture automatique commandée à partir de la poignée facilite encore le mouvement de sortie de la baignoire. L'eau étant admise sous pression dans le vérin 11, celui-ci se détend et soulève donc la poignée 13 lentement et progressivement de la position illustrée en trait plein à la figure 1 jusqu'à la position soulevée illustrée en traits interrompus en 13' à cette même figure. Simultanément, la personne est donc tirée et soulevée par la poignée 13 plus efficacement et progressivement qu'elle le serait par une autre personne qui tenterait de l'aider.In this position, the person then pressurizes the actuator, taking care to place the handle 24 in the actuator supply position and to open the tap, for example for cold water supply 26 from the bathtub. Advantageously, the actuation of the jack 11 is only carried out, at the request of the person, when it is sufficiently supported on the handle 13 for example, by means of a device such as that which will be described later. in relation to FIGS. 3 and 4. Such an automatic opening controlled from the handle further facilitates the movement out of the bathtub. The water being admitted under pressure into the jack 11, the latter relaxes and therefore lifts the handle 13 slowly and gradually from the position illustrated in solid lines in FIG. 1 to the raised position illustrated in broken lines in 13 ' to this same figure. Simultaneously, the person is therefore pulled and lifted by the handle 13 more efficiently and gradually than it would be by another person who would try to help him.

On notera que la force de soulèvement peut être réglée en faisant choix du point d'articulation 19 du levier sur le cadre 12, du choix de la pression d'alimentation d'eau du vérin et du choix de la section de travail du vérin.Note that the lifting force can be adjusted by choosing the point of articulation 19 of the lever on the frame 12, the choice of the water supply pressure of the jack and the choice of the working section of the jack.

Dans l'exemple illustré à la figure 1, le point d'articulation 19 est situé sensiblement au milieu des points 13 et 14, la force du vérin se retrouvant donc sensiblement divisée par 2 au niveau de la poignée 13. Si la pression d'alimentation d'eau est de 3 bars, on voit que pour des diamètres intérieurs du vérin de l'ordre de 4, 5 ou 6 centimètres, on obtient des forces de soulèvement au vérin de 38, 74 ou 84 kilogrammes respectivement. Avantageusement, on placera à l'entrée d'alimentation du vérin un clapet anti-retour évitant une vidange brutale du vérin en cas de rupture du tuyau d'alimentation souple 21 et éventuellement un réducteur de pression qui permettra en outre de régler et maintenir constante la pression d'alimentation du vérin indépendamment des variations de pression d'alimentation de la canalisation de distribution.In the example illustrated in FIG. 1, the articulation point 19 is located substantially in the middle of points 13 and 14, the force of the jack thus being found substantially divided by 2 at the level of the handle 13. If the pressure of water supply is 3 bars, it can be seen that for internal diameters of the cylinder of the order of 4, 5 or 6 centimeters, lifting forces to the cylinder of 38, 74 or 84 kilograms are obtained respectively. Advantageously, a non-return valve will be placed at the supply inlet to the jack, preventing sudden emptying of the jack in the event of rupture of the flexible feed pipe 21 and possibly a pressure reducer which will also make it possible to adjust and maintain constant the supply pressure of the actuator independently of the variations in supply pressure of the distribution pipe.

On fera maintenant référence aux figures 3 et 4 dans lesquelles on a montré un mode de réalisation particulièrement avantageux du vérin 11 permettant à la personne qui veut sortir de son bain de commander automatiquement la mise en eau du vérin à partir de la poignée 13.Reference will now be made to FIGS. 3 and 4 in which a particularly advantageous embodiment of the jack 11 has been shown. allowing the person who wants to get out of his bath to automatically control the watering of the jack from the handle 13.

A la figure 3, on aperçoit l'articulation 17 à la base du vérin 11, et en 30 la tige mobile solidaire du piston 31 du vérin.In FIG. 3, the articulation 17 can be seen at the base of the jack 11, and at 30 the movable rod secured to the piston 31 of the jack.

L'entrée d'eau se fait à la base de la chambre du vérin 11 par un orifice 32 qui communique avec le tuyau souple d'alimentation 21. L'orifice 32 communique avec la chambre 33 du vérin par l'intermédiaire d'une soupape 34 à tiroir dont l'extrémité inférieure porte l'articulation 17 du vérin. La soupape 34 comporte à son extrémité haute une garniture d'étanchéité 35 qui vient porter contre le siège 36 qui communique avec l'orifice 32. La soupape est fermée par l'action d'un ressort 37 qui tire la soupape dans le sens de la flèche 38 en prenant appui sur le pied d'articulation 39 de la soupape, l'autre extémité du ressort 37 venant porter sur une rondelle 40 prenant appui au fond d'un alésage 41 formé dans le pied du vérin 11. Les joints ou garnitures d'étanchéité 42,43 assurent l'étanchéité de la chambre 33 lorsque le vérin est mis sous pression. Il apparaît clairement que si l'on appuie avec suffisamment de force dans le sens de la flèche 44 sur l'extrémité supérieure du vérin, c'est-à-dire sur la tige 30 du piston 31, on va faire descendre l'ensemble du vérin en le faisant coulisser sur la soupape à tiroir 34 en comprimant le ressort 37. Ce faisant, comme illustré à la figure 4, on dégage la garniture d'étanchéité 35 du siège 34, permettant l'alimentation en eau de la chambre 33 et par conséquent commandant l'extension du vérin et le soulèvement de la poignée 13. Cette pression vers le bas sur le vérin 11 est automatiquement appliquée lorsque la personne voulant sortir de la baignoire tire à elle la poignée 13 en s'y accrochant pour en obtenir l'assistance.The water inlet is made at the base of the chamber of the jack 11 by an orifice 32 which communicates with the flexible supply pipe 21. The orifice 32 communicates with the chamber 33 of the jack via a slide valve 34, the lower end of which carries the articulation 17 of the jack. The valve 34 has at its upper end a seal 35 which comes to bear against the seat 36 which communicates with the orifice 32. The valve is closed by the action of a spring 37 which pulls the valve in the direction of the arrow 38 taking support on the hinge foot 39 of the valve, the other end of the spring 37 coming to bear on a washer 40 bearing on the bottom of a bore 41 formed in the foot of the jack 11. The seals or seals 42,43 seal the chamber 33 when the cylinder is pressurized. It is clear that if you press with enough force in the direction of arrow 44 on the upper end of the jack, that is to say on the rod 30 of the piston 31, we will lower the assembly of the jack by sliding it on the slide valve 34 by compressing the spring 37. In doing so, as illustrated in FIG. 4, the gasket 35 is released from the seat 34, allowing the water supply to the chamber 33 and therefore controlling the extension of the jack and the lifting of the handle 13. This downward pressure on the jack 11 is automatically applied when the person wanting to get out of the bathtub pulls the handle 13 by clinging to it. get assistance.

A la figure 3, on aperçoit également un mode de réalisation avantageux du dispositif de vidange 25 constitué par un clapet à ressort. Le dispositif 25 comprend une petite chambre 45 se vissant dans un orifice taraudé 46 formé à la base du vérin 11 et orienté vers la tête de baignoire. A l'intérieur de la chambre est monté un ressort 47 qui applique normalement un clapet 48 contre la face 49 de la chambre 45 venant obturer l'orifice de vidange 50. Le clapet 48 est solidaire d'un bouton pousssoir 51. Pour obtenir la vidange du vérin et donc l'abaissement de la poignée 13, il suffit à la personne qui repose dans sa baignoire d'appuyer sur le bouton poussoir 51.In Figure 3, we also see an advantageous embodiment of the emptying device 25 consisting of a spring valve. The device 25 comprises a small chamber 45 which is screwed into a threaded orifice 46 formed at the base of the jack 11 and oriented towards the bath head. Inside the chamber is mounted a spring 47 which normally applies a valve 48 against the face 49 of the chamber 45 closing the drain orifice 50. The valve 48 is integral with a push button 51. To obtain the emptying of the jack and therefore the lowering of the handle 13, it suffices for the person resting in his bathtub to press the push button 51.

De la description qui précède, il apparaît que le dispositif de l'invention est de construction très simple, fiable et économique, pouvant être réalisé dans des matériaux tout ce qu'il y a de plus courants dans le domaine sanitaire, par exemple en tubes d'acier chromé, laiton, cuivre, etc. Le dispositif ne demande aucun moyen spécial d'adaptation et de mise en place.From the foregoing description, it appears that the device of the invention is of very simple, reliable and economical construction, being able to be produced in all the most common materials in the sanitary field, for example in tubes. chrome steel, brass, copper, etc. The device does not require any special means of adaptation and installation.

Bien entendu, de nombreuses variantes peuvent être apportées au mode de réalisation illustré et décrit.Of course, many variants can be made to the embodiment illustrated and described.

En particulier, le dispositif peut être prévu de façon à être fixé directement au rebord de la baignoire qu'il doit équiper, la baignoire pouvant éventuellement comporter des moyens spéciaux, par exemple deux orifices de fixation pour recevoir le châssis fixe qui y sera bolulonné.In particular, the device can be provided so as to be fixed directly to the rim of the bathtub which it must equip, the bathtub possibly being able to include special means, for example two fixing orifices for receiving the fixed chassis which will be bolted there.

De même, le cadre mobile 12 peut être constitué de façon que sa longueur puisse être réglée par exemple au moyen de tubes télescopiques afin de pouvoir être adapté à la taille de l'utilisateur.Likewise, the movable frame 12 can be constructed so that its length can be adjusted for example by means of telescopic tubes in order to be able to be adapted to the size of the user.

Pour les grands handicapés, on peut prévoir à la place de la poignée 13 un harnais qui pourra prendre la personne par exemple sous les bras, ou encore une sangle.For the severely disabled, one can provide instead of the handle 13 a harness which can take the person for example under the arms, or a strap.

De même, les bras de levier assurant l'assistance pour sortir de la baignoire pourront être aménagés autrement que décrit, selon l'emplacement disponible et les aménagements du local. Par exemple, le vérin pourrait être accroché au plafond. Dans tous les cas, l'important est d'obtenir au moyen d'un vérin à alimentation d'eau une force réglable et progressive permettant de soulever une poignée ou un harnais à laquelle la personne peut s'accrocher, la purge étant obtenue par simple vidange du vérin dans la baignoire.Likewise, the lever arms providing assistance for exiting the bathtub can be fitted out as described, depending on the location available and the layout of the room. For example, the cylinder could be hung from the ceiling. In all cases, the important thing is to obtain, by means of a water supply cylinder, an adjustable and progressive force making it possible to lift a handle or a harness to which the person can hang, the purge being obtained by simple emptying of the cylinder in the bathtub.

On notera également que dans des cas exceptionnels où la distribution d'eau est assurée sous trop faible pression, il est possible d'alimenter le dispositif à partir d'un réservoir d'eau presssuri- sée de petite capacité, dont la pression au niveau souhaitable peut être obtenue par une petite pompe électrique, par exemple à vibreur ou autre.It will also be noted that in exceptional cases where the water distribution is ensured under too low pressure, it is possible to supply the device from a pressurized water tank of small capacity, the pressure at the level desirable can be obtained by a small electric pump, for example vibrator or other.

On se reportera maintenant au mode de réalisation illustré aux figures 6 à 11.We will now refer to the embodiment illustrated in FIGS. 6 to 11.

Comme aux modes de réalisation précédemment décrits, le dispositif d'assistance comprend essentiellement un vérin 111 qui est susceptible d'être alimenté en eau sous pression par un conduit 121 permettant la mise en extension du vérin. Le vérin est articulé à l'une de ses extrémités en 117 en un point fixe solidaire d'une platine support 105 qui sera par exemple fixée au mur (non représenté) à l'aide de vis traversant des orifices tels que 60 formés dans la platine. A son extrémité, la tige du vérin est articulée en 119 autour d'un axe 120 fixé à une extrémité d'un levier 112 tournant autour d'un pivot 114. Dans le mode de réalisation illustré, et comme il apparaît plus clairement à la figure 6, le levier 112 est solidaire d'une bague 61, par exemple soudée à lui, qui tourne autour du pivot 114 par exemple au moyen de roulements à billes 62. Sur la bague 61 est fixé, par exemple par deux vis 63 un chapeau 64 solidaire, par exemple par soudure, d'une extrémité d'un levier tubulaire 65 dont l'autre extrémité porte la poignée 113 d'assistance.As in the previously described embodiments, the assistance device essentially comprises a jack 111 which is capable of being supplied with pressurized water by a conduit 121 allowing the jack to be extended. The jack is articulated at one of its ends at 117 at a fixed point secured to a support plate 105 which will for example be fixed to the wall (not shown) using screws passing through orifices such as 60 formed in the platinum. At its end, the cylinder rod is articulated at 119 around an axis 120 fixed to one end of a lever 112 rotating around a pivot 114. In the illustrated embodiment, and as it appears more clearly from the Figure 6, the lever 112 is integral with a ring 61, for example welded to it, which rotates around the pivot 114 for example by means of ball bearings 62. On the ring 61 is fixed, for example by two screws 63 a cap 64 secured, for example by welding, to one end of a tubular lever 65, the other end of which carries the assistance handle 113.

Avantageusement, et comme il apparaît plus clairement aux figures 7 à 10, la poignée 113 peut se relever à 90°, comme illustré en 113', en étant montée pivotante à l'extrémité libre du levier 65. Comme illustré, le montage peut se faire par exemple en prévoyant un emmanchement sur une certaine longueur I de la poignée 113 dans le levier tubulaire 65 et en formant aux extrémités en regard du levier et de la poignée des secteurs crénélés tels que 66, 67 sur le levier 65 et 68, 69 sur l'extrémité en regard de la poignée 113 permettant un débattement d'environ 90° de la poignée 113 par rapport à l'axe 70 de montage. Une goupille 71 tournant dans deux fentes 72 formées sur un quart de tour dans la paroi rectiligne 73 de la poignée 113 termine le montage.Advantageously, and as it appears more clearly in FIGS. 7 to 10, the handle 113 can be raised by 90 °, as illustrated at 113 ′, by being pivotally mounted at the free end of the lever 65. As illustrated, the mounting can be for example by providing for a fitting over a certain length I of the handle 113 in the tubular lever 65 and by crenellated sectors such as 66, 67 on the lever 65 and 68, 69 on the opposite end of the handle 113 at the opposite ends of the lever and of the handle allowing a clearance of approximately 90 ° of the handle 113 relative to the mounting axis 70. A pin 71 rotating in two slots 72 formed on a quarter turn in the rectilinear wall 73 of the handle 113 completes the assembly.

De cette façon, il est possible de rabattre la poignée 113 à la verticale contre la paroi d'appui sur laquelle le dispositif est monté pour l'escamoter lorsque le dispositif n'est pas utilisé.In this way, it is possible to fold the handle 113 vertically against the support wall on which the device is mounted to retract it when the device is not in use.

A la figure 11 on aperçoit le capot de protection 74 du dispositif qui vient recouvrir tous les organes du dispositif à l'exception de la canalisation 121 d'alimentation en eau, du dispositif de purge 125 et du levier 65 supportant la poignée 113.In FIG. 11, the protective cover 74 of the device can be seen which covers all the organs of the device with the exception of the water supply pipe 121, the purge device 125 and the lever 65 supporting the handle 113.

On remarque que l'organisation du dispositif est telle qu'en prévoyant deux opercules décou- pables 75, 76 dans le capot 74, il est possible, par simple inversion du côté de la platine 105 sur lequel on monte le dispositif, d'avoir un appareil pour fixation à gauche ou à droite selon l'emplacement.It is noted that the organization of the device is such that by providing two cut-out lids 75, 76 in the cover 74, it is possible, by simple inversion of the side of the plate 105 on which the device is mounted, to have a device for fixing to the left or right depending on the location.

Il apparaît clairement que le dispositif peut être encastré dans le mur, auquel cas seuls le levier 65 et la poignée 113 seront apparents, si une niche a été prévue au moment de la construction ou ménagée pour la mise en place du dispositif.It is clear that the device can be built into the wall, in which case only the lever 65 and the handle 113 will be visible, if a recess was provided at the time of construction or provided for the installation of the device.

Avantageusement, le dispositif comprend en outre un ressort 77 ou autre moyen élastique équivalent facilitant la remise en position basse du dispositif après mise en eau du vérin. Le ressort peut être fixé en un point 78 du levier 112 intermédiaire entre les axes 119 et 114, et en un point fixe 79 de la platine. Ainsi, l'abaissement du levier est facilité par mise sous pression du vérin 111, dès qu'on a coupé l'alimentation en eau 121 du vérin et qu'on a ouvert le robinet de vidange 125. On notera que le dispositif peut être utilisé aussi bien pour entrer dans une baignoire que pour en sortir. Pour entrer dans la baignoire, l'utilisateur placera le dispositif en position haute, à la hauteur la plus appropriée. Il lui suffira alors de fermer l'alimentation d'eau 121 et d'ouvrir la vidange 125, une ouverture plus ou moins grande assurant un abaissement progressif plus ou moins rapide de la poignée à laquelle l'utilisateur peut s'agripper.Advantageously, the device further comprises a spring 77 or other equivalent elastic means facilitating the return to the low position of the device after the actuator has been filled with water. The spring can be fixed at a point 78 of the lever 112 intermediate between the axes 119 and 114, and at a fixed point 79 of the plate. Thus, the lowering of the lever is facilitated by pressurizing the jack 111, as soon as the water supply 121 of the jack is cut off and the drain valve 125 is opened. It will be noted that the device can be used for entering and exiting a bathtub. To enter the bathtub, the user will place the device in the high position, at the most appropriate height. It will then suffice to close the water supply 121 and to open the drain 125, a more or less large opening ensuring a more or less rapid progressive lowering of the handle to which the user can grip.

Il apparaît que le dispositif, facilement fixable sur n'importe quelle paroi murale, peut être utilisé en tout autre endroit qu'une salle de bains, par exemple dans des WC ou dans une chambre, pour assister une personne handicapée et lui permettre l'usage, dans des conditions de sécurité, d'une cuvette de WC ou d'un lit.It appears that the device, easily fixed on any wall, can be used anywhere other than a bathroom, for example in a toilet or in a bedroom, to assist a disabled person and allow him to use, under safe conditions, of a toilet bowl or a bed.

Eventuellement, le fluide d'actionnement du vérin peut être constitué par un autre fluide que de l'eau, et par exemple de l'air comprimé, notamment dans une chambre d'hôpital, habituellement équipée d'un circuit d'air sous pression. Dans ce cas, la vidange du vérin laissant échapper de l'air peut dêtre faite à l'air libre directement dans l'atmosphère de la chambre.Optionally, the actuating fluid of the jack can be constituted by a fluid other than water, and for example compressed air, in particular in a hospital room, usually equipped with a pressurized air circuit. . In this case, the emptying of the cylinder allowing air to escape can be made in the open air directly into the atmosphere of the chamber.

Précédemment, et en faisant référence en particulier aux figures 3 et 4, on a décrit un dispositif permettant le soulèvement automatique de la poignée du dispositif, lorsque après sélection de la position convenable de fonctionnement du dispositif, la personne désirant se faire assister se saisit de la poignée et y applique un certain effort.Previously, and with particular reference to FIGS. 3 and 4, a device has been described allowing the automatic lifting of the handle of the device, when, after selection of the suitable operating position of the device, the person wishing to be assisted takes hold of the handle and apply some effort to it.

On décrira maintenant, en faisant référence aux figures 12, 13 et 14, trois variantes de réalisation d'un mécanisme automatique de ce type.We will now describe, with reference to Figures 12, 13 and 14, three alternative embodiments of an automatic mechanism of this type.

Selon le mode de réalisation illustré à la figure 12 et de manière semblable au dispositif illustré aux figures 3 et 4, l'articulation 117 formée à la base du vérin 111 commande une soupape à tiroir 134 pour l'alimentation en eau du vérin. Lorsque aucune pression n'est exercée sur la poignée 113, la soupape 134 a sa garniture d'étanchéité 135 plaquée sur le siège 136, de sorte que l'alimentation en eau de la chambre 133 du vérin est coupée. La soupape 134 est maintenue sur son siège 136 sous l'effet de l'action du ressort 137 dont la force a été calculée de manière à équilibrer largement celle du ressort de rappel 77 agissant par l'intermédiaire du levier 112 en sens inverse (c'est-à-dire tendant à ouvrir la soupape).According to the embodiment illustrated in FIG. 12 and in a similar manner to the device illustrated in FIGS. 3 and 4, the articulation 117 formed at the base of the jack 111 controls a slide valve 134 for the water supply to the jack. When no pressure is exerted on the handle 113, the valve 134 has its packing 135 pressed against the seat 136, so that the water supply to the chamber 133 of the jack is cut off. The valve 134 is maintained on its seat 136 under the effect of the action of the spring 137 whose force has been calculated so as to largely balance that of the return spring 77 acting by means of the lever 112 in the opposite direction (c that is, tending to open the valve).

Comme au mode de réalisation des figures 3 et 4, lorsque l'utilisateur saisit la poignée 113 et s'y aggripe avec un effort suffisant, il comprime le ressort 137 ouvrant la soupape 134. Si l'alimentation en eau 121 du vérin a été préalablement ouverte, le vérin est alors alimenté en eau et la poignée se soulève.As in the embodiment of FIGS. 3 and 4, when the user grasps the handle 113 and grips it with sufficient force, he compresses the spring 137 opening the valve 134. If the water supply 121 of the jack has been previously opened, the cylinder is then supplied with water and the handle is raised.

Le mouvement inverse d'abaissement de la poignée est commandé par simple ouverture du robinet (non représenté) 125 vissé dans l'orifice devidange 146. L'abaissement est obtenu automatiquement sous l'effet du ressort de rappel 77. Si l'on veut utiliser le dispositif comme aide à un mouvement d'abaissement, par exemple pour s'immerger dans une baignoire, ou pour s'asseoir sur un siège WC, il suffit de fermer d'abord l'alimentation en eau 121 du vérin, après quoi il suffit de se saisir de la poignée 113, de s'y agripper et d'ouvrir le robinet de vidange 125 de la grandeur voulue pour obtenir la vitesse d'abaissement progressive désirée de la poignée.The reverse movement of the lowering of the handle is controlled by simple opening of the tap (not shown) 125 screwed into the drain orifice 146. The lowering is obtained automatically under the effect of the return spring 77. If one wishes use the device as an aid in a lowering movement, for example to immerse yourself in a bathtub, or to sit on a WC seat, it is sufficient to first shut off the water supply 121 to the jack, after which it suffices to take hold of the handle 113, to grip it and open the drain valve 125 of the desired size to obtain the desired progressive lowering speed of the handle.

Le mode de réalisation illustré à la figure 13 utilise un dispositif assez semblable à celui de la figure 12, à ceci près que la soupape à tiroir 134' fonctionne de façon inverse à ce qui a été décrit à la figure 12.The embodiment illustrated in FIG. 13 uses a device quite similar to that of FIG. 12, except that the slide valve 134 ′ operates in reverse to what has been described in FIG. 12.

On voit en effet, que telle qu'elle est montée, le ressort 137 agit, en l'absence d'une pression sur la poignée 113, pour maintenir la soupape plaquée sur sa butée basse, c'est-à-dire ouverte, la garniture 135' étant dégagée du siège 136'. En d'autres termes, si l'alimentation en eau du vérin est ouverte, et en l'absence d'un mouvement de traction sur la poignée 113, le dispositif est toujours amené en position haute.It can be seen that, as it is mounted, the spring 137 acts, in the absence of pressure on the handle 113, to keep the valve pressed against its low stop, that is to say open, the lining 135 'being released from the seat 136'. In other words, if the water supply to the jack is open, and in the absence of a pulling movement on the handle 113, the device is always brought to the high position.

Si l'utilisateur se saisit de la poignée 113 et s'y agrippe avec un effort suffisant tendant à abaisser le vérin 111 comme indiqué par la flèche F, le ressort 137 est comprimé, et à l'inverse de ce qui se passait à la figure 12, l'alimentation en eau de la chambre 133 du vérin est coupée. Dans de telles conditions, et dans ces conditions seulement, l'abaissement de la poignée 113 peut être obtenue par ouverture de la vidange 125.If the user takes hold of the handle 113 and there grips with sufficient effort tending to lower the cylinder 111 as indicated by the arrow F, the spring 137 is compressed, and unlike what was happening in FIG. 12, the water supply to the chamber 133 of the cylinder is cut. Under such conditions, and only under these conditions, the lowering of the handle 113 can be obtained by opening the drain 125.

On remarque également que ce dispositif empêche le fonctionnement de soulèvement de la poignée même si la commande en eau du vérin est ouverte, en cas de surcharge assurant la compression du ressort 137. Ce dispositif peut donc servir comme dispositif de sécurité anti- surcharge.It is also noted that this device prevents the lifting operation of the handle even if the water control of the jack is open, in the event of an overload ensuring the compression of the spring 137. This device can therefore serve as an anti-overload safety device.

On décrira maintenant le mode de réalisation illustré à la figure 14 montrant en quelque sorte une combinaison des deux systèmes de sécurité des figures 12 et 13.The embodiment illustrated in FIG. 14 will now be described, somehow showing a combination of the two security systems of FIGS. 12 and 13.

Comme le système de la figure 12, le dispositif comprend une soupape à tiroir 134" qui est normalement maintenue fermée sur son siège 136 par l'action d'un ressort 137, tant qu'une force d'application F de grandeur déterminée n'est pas appliquée au vérin 111. Jusqu'à ce moment, l'alimentation en eau de la chambre 133 du vérin est donc coupée, même si l'alimentation 121 est ouverte.Like the system of FIG. 12, the device comprises a slide valve 134 "which is normally kept closed on its seat 136 by the action of a spring 137, as long as an application force F of determined size does not is not applied to the jack 111. Until this time, the water supply to the chamber 133 of the jack is therefore cut off, even if the feed 121 is open.

Le dispositif comprend en outre pour la soupape à tiroir 134" un second siège 136' contre lequel viendra buter la soupape à tiroir 134" en fin de course lorsque le ressort 137 aura été suffisamment comprimé. Pour une telle compression correspondant à une surcharge d'effort, l'alimentation en eau du vérin est coupé et tout sou- lévement successif de la poignée est interdit. Le dispositif comprend avantageusement un second ressort 80 coaxial au ressort 137 maintenu comprimé sous le pied du vérin, par exemple par une rondelle 81 et un manchon 82 rapporté vissé. Après que la soupape 134" se soit par exemple déplacée sur sa mi-course, le pied 139 de l'articulation 117 vient repousser la rondelle 81 et comprimer le ressort 80, ce qui correspond à un second seuil d'effort déterminé. De cette façon, lorsque l'alimentation en eau du vérin est ouverte, le dispositif fonctionne automatiquement en mouvement de soulèvement dès qu'on s'agrippe à la poignée et y applique un effort suffisant. Par contre, le dispositif s'arrête lorsque l'effort imprimé sur la poignée devient trop grand, dépassant une valeur de surcharge pouvant correspondre à une mauvaise application du dispositif ou à la présence d'un corps étranger présent par inadvertance derrière le levier 65.The device further comprises for the slide valve 134 "a second seat 136 'against which the slide valve 134" will abut at the end of the stroke when the spring 137 has been sufficiently compressed. For such compression corresponding to an overload of effort, the water supply to the jack is cut off and any successive lifting of the handle is prohibited. The device advantageously comprises a second spring 80 coaxial with the spring 137 kept compressed under the foot of the jack, for example by a washer 81 and a sleeve 82 attached screwed. After the valve 134 "has for example moved over its mid-stroke, the foot 139 of the joint 117 pushes the washer 81 and compress the spring 80, which corresponds to a second determined force threshold. In this way, when the water supply to the cylinder is open, the device operates automatically in the lifting movement as soon as one grips the handle and applies sufficient force to it, on the other hand, the device stops when the effort printed on the handle becomes too large, exceeding an overload value which may correspond to improper application of the device or to the presence of a foreign body inadvertently present behind the lever 65.

Pour la vidange du dispositif, on constate que l'appareil fonctionne comme décrit précédemment.For emptying the device, it can be seen that the device operates as described above.

De nombreuses variantes peuvent être apportées aux modes de réalisations décrits.Many variants can be made to the embodiments described.

C'est ainsi par exemple qu'au levier actionné par vérin de l'appareil peut être fixé un câble qui, passant sur des poulies de renvoi, par exemple fixées au plafond d'une pièce, permettra d'accrocher un cintre auquel l'utilisateur pourra se suspendre pour s'aider à se lever ou à se baisser.Thus, for example, a cable can be attached to the lever actuated by the actuator of the device which, passing over idler pulleys, for example fixed to the ceiling of a room, will allow a hanger to be hung on which the user will be able to suspend himself to help him get up or down.

De la même façon, un seul et même appareil peut permettre l'actionnement de plusieurs câbles en parallèle auxquels seront accrochés des cintres aux divers endroits utiles dans une pièce. Ainsi, un appareil monté dans une salle de bains pourra actionner trois cintres respectivement à l'emplament de la baignoire, de la cuvette de WC et d'un bidet.In the same way, a single device can allow the actuation of several cables in parallel to which hangers will be hung at the various useful places in a room. Thus, a device mounted in a bathroom can activate three hangers respectively at the location of the bath, the toilet bowl and a bidet.

On remarquera que les dispositifs tels en particulier que décrits aux figures 5, 12 et 14 permettent un abaissement automatique du levier. Ainsi, l'abaissement du levier est automatique dès qu'on ouvre le robinet de vidange 125 et ceci sans coupure d'alimentation en eau du vérin. Cette manoeuvre peut être effectuée par la personne une fois dans la baignoire si elle y est entrée sans abaisser le levier ou sans s'y agripper.Note that the devices as in particular as described in Figures 5, 12 and 14 allow an automatic lowering of the lever. Thus, the lowering of the lever is automatic as soon as the drain valve 125 is opened and this without cutting the water supply to the jack. This maneuver can be carried out by the person once in the bathtub if they have entered it without lowering the lever or without gripping it.

On notera que de façon générale l'appareil est conçu pour que sa mise en place dans une salle de bain puisse se faire commodément et discrètement.It will be noted that in general the device is designed so that its installation in a bathroom can be done conveniently and discreetly.

Si on prévoit un débit de vidange suffisamment important l'abaissement du vérin peut être obtenu par simple ouverture de la vidange, l'alimentation en eau pouvant être maintenue.If a sufficiently large drain flow rate is provided, the lowering of the jack can be obtained by simply opening the drain, the water supply being able to be maintained.

Le rappel en position haute du levier peut être obtenu par des tendeurs en caoutchouc ou analogues qui pourront remplacer avantageusement les ressorts de rappels en acier.The return to the high position of the lever can be obtained by rubber tensioners or the like which can advantageously replace the return springs in steel.

Si la fixation du vérin sur un mur voisin de la baignoire est délicate, on peut prévoir le montage du vérin sur un pied support qui sera en partie engagée sous la baignoire.If the fixing of the jack to a wall near the bathtub is difficult, one can provide for the mounting of the jack on a support leg which will be partly engaged under the bathtub.
