Abstract

The invention concerns a device comprising an elongated handle (4) at the end of which are arranged means (2, 3) for holding food (7). The means (2, 3) comprise two symmetrical parts arranged symmetrically relatively to the handle (4) longitudinal axis (L). Each of the parts (2, 3) can be spaced apart and brought together in rotation about pins (5, 6) parallel to the handle (4) axis. Thus, when the parts are brought together they form the hollow part of a spoon, the prongs of a fork or jaw-like grippers. The device comprises an electronic control for spacing apart or bringing together the parts (2, 3) by applying them on a surface, for example the surface of a plate.

Description

La présente invention a pour objet un dispositif automatique pour handicapé physique, notamment pour la saisie de la nourriture dans une assiette.The present invention relates to an automatic device for the disabled physical, especially for entering food on a plate.

La saisie d'un morceau de nourriture déterminé dans une assiette pose souvent de difficiles problèmes à un handicapé.
Privé d'une main ou souffrant d'un manque de coordination, il éprouve souvent de la difficulté à pousser le morceau de son choix sur une fourchette ou cuillère avant de la porter à la bouche.
Même munie d'un rebord rehaussé servant de butée à la nourriture, l'assiette spéciale ne résout que partiellement le problème. En glissant, la cuillère ou la fourchette sur le fond de l'assiette jusqu'au rebord, il ne sera pas rare que la bouchée souhaitée se retrouve sur la table, en dépit du rehaussement extérieur de l'assiette.Entering a certain piece of food on a plate often poses difficult problems for a disabled person.
Deprived of one hand or suffering from a lack of coordination, he often finds it difficult to push the piece of his choice on a fork or spoon before bringing it to the mouth.
Even with a raised rim serving as a stop for food, the special plate only partially solves the problem. By sliding, the spoon or the fork on the bottom of the plate to the rim, it will not be rare that the desired bite is found on the table, despite the external enhancement of the plate.

On connaít par le document US-A-1 535 600 (GODDU) un dispositif pour prendre des sucreries. Ce dispositif comporte un manche allongé à l'extrémité duquel sont disposés des moyens pour saisir de la nourriture, notamment des sucreries. Lesdits moyens destinés à saisir de la nourriture comprennent deux parties symétriques disposées symétriquement relativement à l'axe longitudinal du manche, chacune d'elles pouvant s'écarter et se rapprocher en rotation excentrée autour d'axes parallèles à l'axe longitudinal du manche de manière à former une pince, qui lorsque lesdites parties sont en position rapprochées constituent un moyen de pince permettant de saisir de la nourriture. Ce dispositif est utile pour saisir de la nourriture et la déposer ailleurs, mais il ne pourra en aucun cas être employé par un handicapé pour porter de la nourriture à sa bouche. Document US-A-1,535,600 (GODDU) discloses a device for take sweets. This device has an elongated handle at the end which are arranged means for grasping food, in particular sweets. Said means for gripping food comprises two symmetrical parts arranged symmetrically relative to the longitudinal axis of the handle, each of them being able to deviate and approach in rotation eccentric around axes parallel to the longitudinal axis of the handle so as to forming a clamp, which when said parts are in close position are a gripper means for gripping food. This device is useful for picking up food and dropping it off elsewhere, but does not may in no case be used by a disabled person to carry food to his mouth.

L'invention a pour but de fournir un dispositif, qui permet d'éviter ces inconvénients. En effet, le dispositif automatique pour handicapé physique défini à la revendication 1 est conçu de manière à ce que, une fois choisie la bouchée puisse être saisie avec précision et sans qu'elle ne puisse s'échapper et ceci d'une seule main.The object of the invention is to provide a device which makes it possible to avoid these disadvantages. Indeed, the automatic device for the physically handicapped defined in claim 1 is designed so that, once chosen the bite can be grasped accurately and without escape and this with one hand.

L'invention vise à réaliser une indépendance du handicapé qui pourra, sans aide extérieure, saisir sélectivement une nourriture solide ou liquide d'une assiette conventionnelle. Les fonctions difficiles ou impossibles pour un handicapé sont effectuées par un mécanisme motorisé commandé par un circuit électronique.The invention aims to achieve independence for the disabled who can, without outside help, selectively grab solid or liquid food from a conventional plate. Difficult or impossible functions for a disabled are carried out by a motorized mechanism controlled by a electric circuit.

L'invention sera mieux comprise et ses caractéristiques, ainsi que ses avantages apparaítront plus clairement à la lecture de la description de réalisations, donnée à titre d'exemple, en regard des dessins sur lesquels :

  • La figure 1 représente une forme d'exécution de l'invention réalisée sous forme d'une cuillère.
  • La figure 2 représente un détail du mécanisme d'un dispositif selon l'invention.
  • La figure 3 représente une variante du dispositif de la figure 1.
  • La figure 4 représente une variante d'un dispositif selon l'invention.
    • The invention will be better understood and its characteristics, as well as its advantages, will appear more clearly on reading the description of embodiments, given by way of example, with reference to the drawings in which:
  • FIG. 1 represents an embodiment of the invention produced in the form of a spoon.
  • Figure 2 shows a detail of the mechanism of a device according to the invention.
  • FIG. 3 represents a variant of the device of FIG. 1.
  • FIG. 4 represents a variant of a device according to the invention.

    • Comme on le voit sur la figure1 un dispositif selon l'invention comporte un manche 4 à l'extrémité du duquel sont disposés deux parties 2 et 3 constituant un moyen de saisie de la nourriture. Dans la forme d'exécution de la figure 1 ce moyen de saisie constitue, dans une position déterminée des deux parties, la partie creuse d'une cuillère, mais cela pourrait aussi constituer une pince pour saisir des spaghettis, par exemple, comme représenté à la figure 3.As can be seen in FIG. 1, a device according to the invention comprises a handle 4 at the end of which are arranged two parts 2 and 3 constituting a means of seizing food. In the embodiment of Figure 1 this means of seizure constitutes, in a determined position of the two parties, the hollow part of a spoon, but this could also be a forceps for sear spaghetti, for example, as shown in Figure 3.

    En revenant à la figure 1, on constate que les deux parties 2 et 3 sont constituées par deux demi-coquilles symétriques selon l'axe longitudinal L de la partie creuse d'une cuillère. Chaque demi coquille 2 et 3 pouvant s'écarter en rotation pour permettre la saisie de la nourriture sélectionnée, puis se refermer pour reconstituer la partie creuse d'une cuillère normale à l'intérieur de laquelle l'on retrouvera la nourriture choisie (fig. 1c).Returning to Figure 1, we see that the two parts 2 and 3 are formed by two symmetrical half-shells along the longitudinal axis L of the hollow part of a spoon. Each half shell 2 and 3 can deviate in rotation to allow entry of the selected food, then close to reconstitute the hollow part of a normal spoon inside from which we will find the chosen food (fig. 1c).

    De simples pressions transmises de l'utilisateur par le manche 4 sur les coquilles 2, 3 commandent respectivement fermeture puis ouverture des deux coquilles par rotation de celles-ci selon les angles α autour des axes moteurs 5, 6 tournant en sens inverse.Simple pressures transmitted from the user by the handle 4 on the shells 2, 3 respectively command closing and then opening of the two shells by rotation thereof according to the angles α around the motor axes 5, 6 turning in opposite direction.

    En position ouverte, l'utilisateur sélectionne la nourriture 7, appuie sur les deux coquilles 2, 3 lesquelles vont se refermer sur le morceau de nourriture 7. Ce dernier ne pourra s'échapper et se retrouvera captif à l'intérieur de la cuillère ou de la forme de saisie reconstituée.In the open position, the user selects the food 7, presses the two shells 2, 3 which will close on the piece of food 7. This the latter cannot escape and will be trapped inside the spoon or the reconstituted form of seizure.

    Une fois vidée de son contenu, une nouvelle pression sur la cuillère contre le bord ou le fond de l'assiette ouvrira les deux coquilles 2, 3.Once emptied of its contents, a new pressure on the spoon against the edge or bottom of the plate will open the two shells 2, 3.

    La force motrice est fournie par un groupe moteur-réducteur miniature 8, fig. 1a et fig. 2, constituant un ensemble rigide1 alimenté par la batterie 21, dont le pignon 9 du réducteur actionne deux engrenages 10, 11 identiques, l'un d'eux étant solidaire d'une roue dentée 12 entraínée par ledit pignon moteur 9.The driving force is provided by a miniature motor-reduction unit 8, fig. 1a and fig. 2, constituting a rigid assembly1 supplied by the battery 21, the pinion 9 of the reducer drives two identical gears 10, 11, one of them being integral with a toothed wheel 12 driven by said motor pinion 9.

    Les deux coquilles 2, 3 entraínées par deux canons 22, 23 solidaires des engrenages 10, 11 sont amovibles, facilitant leur nettoyage après usage ; elles sont entraínées, via un prisonnier et positionnées selon les axes 5 et 6 par des aimants 13, 14 intégrés respectivement dans les roues dentées 10, 11. The two shells 2, 3 entrained by two cannons 22, 23 integral with the gears 10, 11 are removable, facilitating their cleaning after use; they are entrained, via a prisoner and positioned along axes 5 and 6 by magnets 13, 14 integrated respectively in the toothed wheels 10, 11.

    L'angle du mouvement souhaitable effectué par les coquilles 2, 3 est défini par des butées 15, 16 ( fig. 2), constituées dans l'ensemble rigide 1 du groupe moteur-réducteur.The angle of the desirable movement performed by the shells 2, 3 is defined by stops 15, 16 (fig. 2), formed in the rigid assembly 1 of the group motor reducer.

    Le moteur est alimenté pendant une durée prédéterminée par un circuit électronique 17 (fig. 1a) dans le sens de rotation qui convient. Un verrouillage électronique empêche l'ouverture des coquilles pendant un temps réglable, de manière à ce qu'une pression involontaire dans la bouche de l'opérateur ne puisse en commander l'ouverture.The motor is powered for a predetermined time by an electronic circuit 17 (fig. 1a) in the appropriate direction of rotation. A electronic lock prevents opening of the shells for a while adjustable, so that an involuntary pressure in the mouth of the operator cannot control opening.

    Une variante consiste à faire ouvrir les deux coquilles après un temps déterminé, qui peut être en fonction des spécificités de l'utilisateur.A variant consists in opening the two shells after a time determined, which can be based on the specifics of the user.

    En butée d'ouverture ou fermeture des deux coquilles 2, 3 l'énergie du groupe moteur-réducteur est absorbée par un limiteur de couple mécanique, tandis qu'un limiteur électronique coupe l'alimentation du moteur.When the two shells 2, 3 open or close, the energy of the group motor-reducer is absorbed by a mechanical torque limiter, while an electronic limiter cuts the power to the motor.

    Le départ de la séquence est donné par le contact 18 (fig. 1a), actionné par une légère pression sur le manche 4 dont le mouvement relatif par rapport à l'ensemble moteur-réducteur circuit électronique autour de l'axe de pivotement 19 (fig. 1 et fig. 2) est ramené en position initiale par le ressort 20.The start of the sequence is given by contact 18 (fig. 1a), actuated by a slight pressure on the handle 4 whose relative movement relative to the motor-reducer assembly of the electronic circuit around the pivot axis 19 (fig. 1 and fig. 2) is returned to the initial position by the spring 20.

    Une deuxième pression ou impulsion du contact 18 ouvrira les deux coquilles, toutefois avec une temporisation d'inhibition. Une pression d'ouverture ou fermeture trop brève ne sera pas enregistrée pour tenir compte de mouvements involontaires furtifs de l'utilisateur.A second pressure or pulse of contact 18 will open the two shells, however with an inhibition delay. Opening pressure or closing too short will not be recorded to take account of involuntary stealthy movements of the user.

    Une autre variante consiste à permettre l'ouverture des coquilles 2, 3 non plus par temporisation, mais par un acte volontaire consistant à tenir le manche approximativement vertical, coquilles dirigées vers le haut ou le bas. Another variant consists in allowing the opening of the shells 2, 3 either by time delay, but by a voluntary act of holding the handle approximately vertical, shells pointing up or down.

    Dans ces deux positions, volontaires et fugitives seulement, une mémoire activée par un contact décrit ci-après, donnera soit l'autorisation de fermeture qui s'opérera dès la pression des coquilles sur une surface, soit directement l'ordre de fermeture de ces dernières.In these two positions, voluntary and fugitive only, a memory activated by a contact described below, will give either the authorization to close which will operate as soon as the shells are pressed on a surface, either directly the closing order of these.

    Ce mode de sécurité protège l'utilisateur de tout risque de fermeture du dispositif de saisie par une fausse manoeuvre.This security mode protects the user from any risk of closing the device for seizure by a false maneuver.

    La fermeture fugitive d'un contact en position verticale est obtenue par une bille 24 (fig. 4), introduite dans un anneau de révolution 25, dont les parois intérieures 26 sont presque verticales, l'axe L du dispositif de saisie étant horizontal. Les deux faces externes de l'anneau 25 sont fermées par une plaque métallique 27, isolée électriquement de l'anneau 25 par une rondelle 28 ouverte en son centre de manière à ce que la bille 24 puisse établir un contact électrique entre l'anneau 25 et la plaque métallique 27. Ceci n'interviendra que lorsque l'axe L sera approximativement vertical, permettant à la bille 24 de rouler vers le centre et activer une mémoire.The fleeting closure of a contact in vertical position is obtained by a ball 24 (fig. 4), introduced into a ring of revolution 25, the walls of which interior 26 are almost vertical, the axis L of the gripping device being horizontal. The two external faces of the ring 25 are closed by a metal plate 27, electrically insulated from the ring 25 by a washer 28 open in its center so that the ball 24 can establish contact between the ring 25 and the metal plate 27. This will only happen when the L axis is approximately vertical, allowing ball 24 to roll towards the center and activate a memory.

    Une prise de nourriture donne lieu à un transfert du dispositif de saisie approximativement horizontal, en particulier pour les liquides, sur le parcours assiette bouche et retour, de sorte que la position verticale marque une volonté délibérée qu'il serait difficile d'effectuer lorsque le dispositif de saisie est dans la bouche.Food intake results in transfer of the gripping device approximately horizontal, especially for liquids, on the course mouth and back plate, so that the vertical position marks a will deliberate that it would be difficult to perform when the gripping device is in the mouth.

    Une combinaison d'une temporisation et du dispositif ci-dessus est également possible tout comme une fermeture de contact semblable à celui décrit mais opérant par rotation du manche autour de son axe L longitudinal plutôt que de le placer verticalement.A combination of a timer and the above device is also possible just like a contact closure similar to that described but operating by rotating the handle around its longitudinal axis L rather than place it vertically.
