Description

La présente invention concerne un dispositif d'assistance à l'ouverture d'un tiroir d'un meuble ou similaire.The present invention relates to an assistance device for opening a drawer of a piece of furniture or the like.

Le document FR 2 181 287 décrit un dispositif d'assistance à l'ouverture d'un tiroir d'une armoire. Le dispositif d'assistance décrit dans ce document comporte un support monté sur le bâti du meuble, un poussoir destiné à coopérer avec le tiroir, une première et une seconde barres de liaison reliées l'une à l'autre en croix par une articulation, la première barre de liaison comprenant une première extrémité montée articulée sur le support et une seconde extrémité montée coulissante sur le poussoir, et la seconde barre de liaison comprenant une première extrémité montée articulée sur un organe de guidage monté coulissant sur le support et une seconde extrémité montée articulée sur le poussoir. Le dispositif d'assistance comporte en outre des moyens d'entraînement agencés pour entraîner en coulissement l'organe de guidage entre une position de fermeture dans laquelle les premières extrémités des barres de liaison sont éloignées l'une de l'autre et le poussoir est rapproché du support, et une position d'ouverture dans laquelle les premières extrémités des barres de liaison sont rapprochées l'une de l'autre et le poussoir est éloigné du support.The document FR 2 181 287 discloses an assistance device for opening a drawer of a cabinet. The assistance device described in this document comprises a support mounted on the furniture frame, a pusher for cooperating with the drawer, a first and a second connecting bar connected to one another in a cross manner by a hinge, the first connecting bar comprising a first end mounted articulated on the support and a second end slidably mounted on the pusher, and the second connecting bar comprising a first end mounted articulated on a guide member slidably mounted on the support and a second end articulated rise on the pusher. The assistance device further comprises driving means arranged to slidably drive the guide member between a closed position in which the first ends of the connecting bars are spaced apart from each other and the pusher is close to the support, and an open position in which the first ends of the connecting bars are brought closer to each other and the pusher is removed from the support.

Un tel dispositif d'assistance présente une structure complexe et ne permet la transmission au tiroir d'une force de poussée suffisamment élevée pour permettre un déplacement aisé du tiroir lorsque celui-ci est relativement lourd.Such a support device has a complex structure and does not allow the transmission to the drawer of a pushing force high enough to allow easy movement of the drawer when it is relatively heavy.

La présente invention vise à remédier à ces inconvénients.The present invention aims to remedy these disadvantages.

Le problème technique à la base de l'invention consiste donc à fournir un dispositif d'assistance qui soit de structure simple, économique et fiable, qui présente un faible encombrement, et qui permette la transmission au tiroir d'une force de poussée élevée.The technical problem underlying the invention therefore consists in providing a support device which is simple in structure, economical and reliable, which has a small footprint, and which allows the transmission to the drawer of a high thrust force.

A cet effet, la présente invention concerne un dispositif d'assistance à l'ouverture d'un tiroir d'un meuble ou similaire, caractérisé en ce qu'il comporte :

  • un support destiné à être monté sur le bâti du meuble,
  • un poussoir destiné à coopérer avec le tiroir,
  • des moyens de liaison, conformés en parallélogramme déformable, reliant le support au poussoir et déformables entre une position d'ouverture dans laquelle le poussoir est éloigné du support et une position de fermeture dans laquelle le poussoir est rapproché du support, et
  • des moyens d'actionnement agencés pour déformer les moyens de liaison entre leurs positions d'ouverture et de fermeture.
For this purpose, the present invention relates to a device for assisting the opening of a drawer of a piece of furniture or the like, characterized in that it comprises:
  • a support intended to be mounted on the frame of the furniture,
  • a pusher for cooperating with the drawer,
  • connecting means, shaped as a deformable parallelogram, connecting the support to the pusher and deformable between an open position in which the pusher is removed from the support and a closed position in which the pusher is brought closer to the support, and
  • actuating means arranged to deform the connecting means between their open and closed positions.

Le fait que les moyens de liaison sont conformés en parallélogramme déformable assure la transmission d'une force de poussée suffisamment élevée pour permettre un déplacement aisé du tiroir quel que soit le poids de ce dernier. Ces dispositions évitent ainsi une usure prématurée des moyens d'actionnement.The fact that the connecting means are shaped deformable parallelogram ensures the transmission of a pushing force high enough to allow easy movement of the drawer regardless of the weight of the latter. These provisions thus prevent premature wear of the actuating means.

En outre, cette forme des moyens de liaison permet d'obtenir un dispositif d'assistance de structure simple et économique, et de faible encombrement.In addition, this form of connecting means provides a simple structure of assistance and economic, and small footprint.

De plus, cette forme des moyens de liaison permet de pousser le tiroir en n'importe quel point de sa largeur avec le même degré d'efficacité. Il est ainsi possible d'adapter le poussoir de telle sorte que ce dernier coopère avec la face arrière du tiroir sur une portion allant du centre aux extrémités de cette face arrière.In addition, this form of the connecting means makes it possible to push the drawer at any point of its width with the same degree of efficiency. It is thus possible to adapt the pusher so that it cooperates with the rear face of the drawer on a portion from the center to the ends of the rear face.

Cette configuration des moyens de liaison permet également d'assurer une poussée sur le tiroir selon un axe parallèle à la direction d'ouverture de ce dernier sans exercer de frottements sur le tiroir.This configuration of the connecting means also ensures a push on the slide along an axis parallel to the opening direction of the latter without exerting friction on the drawer.

De préférence, les moyens de liaison et les moyens d'actionnement sont conçus de telle sorte que la courbe de vitesse du poussoir lors de ses déplacements de sa position d'ouverture à sa position de fermeture présente une forme en arc de cercle. Ces dispositions permettent d'obtenir une poussée douce et constante sur le tiroir sur sa course d'éjection.Preferably, the connecting means and the actuating means are designed so that the velocity curve of the pusher during its movements from its open position to its closed position has an arcuate shape. These provisions allow to obtain a gentle and constant push on the drawer on its ejection stroke.

It should be noted that the number of revolutions measured by the encoder decreases as a function of the increase of the mass of the spool and that each control law is predefined to be used for a given mass range. This design of the motor and the control means makes it possible to automatically adapt the control law of the motor according to the mass of the slide, and thus to use an optimum driving force to ensure that the slide is opened at a substantially identical speed. whatever the mass of the drawer. Thus, regardless of the impetus performed on the front face of the drawer and its loading, the drawer is always expelled at the same opening speed and its output stroke is substantially the same.

La durée prédéterminée peut être par exemple d'environ une seconde et la mesure du nombre de tours est de préférence effectuée en début d'ouverture du tiroir.The predetermined duration may be for example about one second and the measurement of the number of revolutions is preferably performed at the beginning of opening of the drawer.

Chaque organe de guidage 12, 14 est de préférence réalisé en matière plastique, et avantageusement en matière plastique à faible coefficient de frottement. Chaque organe de guidage 12, 14 comporte deux broches d'articulation 16, 17 d'axes verticaux confondus portées respectivement par deux faces opposées dudit organe de liaison.The connecting means comprise a first connecting member 12 having a through bore 13 unthreaded, and a second connecting member 14 having a through bore 15 internally threaded. Each guide member 12, 14 is preferably made of plastic material, and advantageously of plastic material with a low coefficient of friction. Each guide member 12, 14 has two hinge pins 16, 17 vertical axes combined respectively carried by two opposite faces of said connecting member.

Les moyens de liaison comportent en outre une première paire de bielles comportant une première bielle 18 dont les extrémités sont respectivement montées pivotantes d'une part autour d'un axe vertical matérialisé par deux broches d'articulation 19 portées par le support 3 et d'autre part autour d'un axe vertical matérialisé par les deux broches d'articulation 16 portées par le premier organe de liaison 12, et une seconde bielle 20 dont les extrémités sont respectivement montées pivotantes autour d'un axe vertical matérialisé par deux broches d'articulation 21 portées par le support 3 et d'autre part autour d'un axe vertical matérialisé par les broches d'articulation 17 portées par le second organe de liaison 14.

Les deux paires de broches d'articulation 23, 25 sont décalées l'une de l'autre selon une direction perpendiculaire à la direction d'ouverture / fermeture du tiroir.The connecting means also comprise a second pair of connecting rods comprising a third connecting rod 22, the ends of which are respectively pivotally mounted on the one hand about a vertical axis represented by two articulation pins 23 carried by the pusher 5 and on the other hand part about a vertical axis materialized by the two hinge pins 16 carried by the first connecting member 12, and a fourth connecting rod 24 whose ends are respectively pivotally mounted about a vertical axis materialized by two hinge pins 25 carried by the pusher 5 and secondly around a vertical axis shown by the two hinge pins 17 carried by the second connecting member 14. The two pairs of hinge pins 23, 25 are offset one of the other in a direction perpendicular to the direction of opening / closing of the drawer.

Chacune des première, seconde, troisième et quatrième bielles 18, 20, 22, 24 comporte une portion centrale, et deux branches latérales solidaires de la portion centrale. Chaque branche latérale comporte un oeillet à proximité de chacune de ses extrémités. Il convient de noter que les portions centrales des différentes bielles sont conformées pour permettre un encastrement des première et troisième bielles 18, 22 et un encastrement des seconde et quatrième bielles 20, 24 lorsque les moyens de liaison sont dans leurs positions de fermeture.Each of the first, second, third and fourth links 18, 20, 22, 24 comprises a central portion, and two lateral branches integral with the central portion. Each side branch has an eyelet near each of its ends. It should be noted that the central portions of the different connecting rods are shaped to allow recessing of the first and third connecting rods 18, 22 and a recessing of the second and fourth links 20, 24 when the connecting means are in their closed positions.

Le dispositif d'assistance 2 comporte de plus des moyens d'actionnement agencés pour déformer les moyens de liaison entre leurs positions d'ouverture et de fermeture.The assistance device 2 further comprises actuating means arranged to deform the connecting means between their open and closed positions.

Les moyens d'actionnement comportent une tige de manoeuvre 26 agencée pour coopérer avec les premier et second organes de liaison 12, 14 de manière à déplacer relativement ces derniers entre une première position (montrée sur les figure 3 et 5) dans laquelle ils sont rapprochés l'un de l'autre et les moyens de liaison sont dans leur position d'ouverture, et une seconde position (montrée sur les figures 2 et 4) dans laquelle ils sont éloignés l'un de l'autre et les moyens de liaison sont dans leur position de fermeture.The actuating means comprise an operating rod 26 arranged to cooperate with the first and second connecting members 12, 14 so as to relatively move the latter between a first position (shown in FIGS. figure 3 and 5 ) in which they are brought closer to one another and the connecting means are in their open position, and a second position (shown on the figures 2 and 4 ) in which they are distant from each other and the connecting means are in their closed position.

La tige de manoeuvre 26 présente une première portion 27 non filetée montée mobile en rotation dans l'alésage 13 du premier organe de liaison 12, et une seconde portion 28 filetée extérieurement agencée pour coopérer avec l'alésage fileté 15 du second organe de liaison 14.The operating rod 26 has a first unthreaded portion 27 mounted rotatably in the bore 13 of the first connecting member 12, and a second threaded portion 28 externally arranged to cooperate with the threaded bore 15 of the second connecting member 14. .

Les moyens d'actionnement comportent en outre un moteur électrique réversible 29 dont l'arbre de sortie 30 est couplé en rotation avec la tige de manoeuvre 26 de manière à entraîner en rotation cette dernière respectivement dans un premier sens de façon à déplacer les premier et second organes de liaison 12, 14 de leur première position vers leur seconde position, et dans un second sens de façon à déplacer les premier et second organes de liaison 12, 14 de leur seconde position vers leur première position.The actuating means further comprise a reversible electric motor 29 whose output shaft 30 is coupled in rotation with the operating rod 26 so as to rotate the latter respectively in a first direction so as to move the first and second connecting members 12, 14 from their first position to their second position, and in a second direction so as to move the first and second connecting members 12, 14 from their second position to their first position.

Le moteur électrique 29 comporte un carter 31 solidaire du premier organe de liaison 12. Le carter 31 du moteur électrique 29 est solidarisé au premier organe de liaison 12 par l'intermédiaire d'une couronne 32, entourant la tige de manoeuvre 26, fixée d'une part sur une extrémité du premier organe de liaison 12 et d'autre part sur une extrémité du carter 31 du moteur.The electric motor 29 comprises a housing 31 secured to the first connecting member 12. The housing 31 of the electric motor 29 is secured to the first connecting member 12 via a ring 32, surrounding the operating rod 26, fixed by on one side on one end of the first connecting member 12 and on the other hand on one end of the housing 31 of the motor.

Le dispositif d'assistance 2 comporte également des moyens de commande agencés pour commander le fonctionnement du moteur électrique. Les moyens de commande comportent un capteur de force 33 monté sur le poussoir 5 entre le corps 6 et la plaque métallique 7 du poussoir 5. Il convient toutefois de noter que la zone de détection du capteur de force 33 est intercalée entre la portion de montage de l'élément d'amortissement 8 et le corps 6 du poussoir 5. Le capteur de force 33 est ainsi agencé pour mesurer la force exercée par le tiroir sur le poussoir 5. Le capteur de force 33 est par exemple monté sur le corps 6 du poussoir 5 par l'intermédiaire d'un adhésif double-face ou surmoulé dans le corps 6 ou l'élément d'amortissement 8.The assistance device 2 also comprises control means arranged to control the operation of the electric motor. The control means comprise a force sensor 33 mounted on the pusher 5 between the body 6 and the metal plate 7 of the pusher 5. It should however be noted that the detection zone of the force sensor 33 is interposed between the mounting portion of the damping element 8 and the body 6 of the pusher 5. The force sensor 33 is thus arranged to measure the force exerted by the slide on the pusher 5. The force sensor 33 is for example mounted on the body 6 the pusher 5 by means of a double-sided adhesive or overmolded in the body 6 or the damping element 8.

Les moyens de commande comportent en outre des moyens de contrôle conçus pour commander le fonctionnement du moteur électrique 29 lorsque la force mesurée par le capteur de force 33 est supérieure ou égale à une valeur prédéterminée. Les moyens de contrôle pourraient par exemple comporter un microprocesseur.The control means further comprise control means adapted to control the operation of the electric motor 29 when the force measured by the force sensor 33 is greater than or equal to a predetermined value. The control means could for example include a microprocessor.

Le fonctionnement du dispositif d'assistance est le suivant.The operation of the assistance device is as follows.

On supposera que les moyens de liaison sont dans leur position de fermeture et que le tiroir est en position fermée (montrée sur la figure 10), c'est-à-dire que la face arrière du tiroir est au contact du poussoir 5.It will be assumed that the connecting means are in their closed position and that the drawer is in the closed position (shown on the figure 10 ), that is to say that the rear face of the drawer is in contact with the pusher 5.

Pour ouvrir le tiroir, un utilisateur doit exercer une pression sur la face avant du tiroir suffisante pour que le capteur de force 33 porté par le poussoir 5 détecte une force supérieure ou égale à la valeur prédéterminée. Dans ce cas, les moyens de contrôle commandent l'alimentation du moteur électrique 29 de telle sorte que ce dernier entraîne en rotation la tige de manoeuvre 26 dans le sens correspondant à un rapprochement des premier et second organes de liaison 12, 14. Il s'en suit un déplacement du poussoir 5 dans sa position d'ouverture et donc un déplacement du tiroir vers sa position ouverte (montrée sur la figure 11). Il convient de noter que la poussée exercée par le poussoir 5 sur le tiroir s'exerce uniquement sur le début de la course du tiroir vers sa position ouverte, l'ouverture complète de ce dernier se réalisant du fait de l'inertie liée à la poussée initiale.To open the drawer, a user must exert pressure on the front of the drawer sufficient for the force sensor 33 carried by the pusher 5 detects a force greater than or equal to the predetermined value. In this case, the control means control the power supply of the electric motor 29 so that the latter rotates the operating rod 26 in the direction corresponding to a bringing together of the first and second connecting members 12, 14. follows a movement of the pusher 5 in its open position and therefore a displacement of the slide towards its open position (shown on the figure 11 ). It should be noted that the thrust exerted by the pusher 5 on the drawer is exerted solely on the beginning of the travel of the drawer towards its open position, the complete opening of the latter being realized because of the inertia related to the initial thrust.

Ensuite, les moyens de contrôle commandent une alimentation du moteur 29 de telle sorte que ce dernier entraîne en rotation la tige de manoeuvre 26 dans le sens correspondant à un éloignement des premier et second organes de liaison 12, 14 et donc à un déplacement du poussoir 5 dans sa position de fermeture.Then, the control means control a supply of the motor 29 so that the latter rotates the operating rod 26 in the direction corresponding to a distance of the first and second connecting members 12, 14 and therefore to a displacement of the pusher 5 in its closed position.

Pour fermer le tiroir, l'utilisateur pousse ce dernier vers sa position fermée, la fermeture complète du tiroir étant facilitée par l'intermédiaire de ressorts de rappel intégrés aux glissières du tiroir assurant une fermeture automatique du tiroir sur la fin de course de ce dernier, par exemple sur les cinquante derniers millimètres.To close the drawer, the user pushes the latter to its closed position, the complete closure of the drawer being facilitated by means of return springs integrated drawer slides ensuring automatic closure of the drawer on the end of the latter , for example on the last fifty millimeters.

Les figures 13 à 17 représentent un dispositif d'assistance selon un second mode de réalisation qui diffère de celui représenté sur les figures 1 à 12 essentiellement en ce que chaque organe de liaison 12, 14 comporte :

  • une première pièce 40, 40' sensiblement parallélépipédique dans laquelle sont ménagés l'alésage 13, 15 correspondant destiné à coopérer avec la tige de manoeuvre 26 et un logement traversant 41, 41' dans lequel débouche l'alésage 13, 15 correspondant,

  • un ressort hélicoïdal 44, 44', monté autour de la tige de manoeuvre 26 et interposé entre les première et seconde pièces correspondantes, agencé pour solliciter la seconde pièce 42, 42' dans sa première position.
The Figures 13 to 17 represent an assistance device according to a second embodiment which differs from that shown in the Figures 1 to 12 essentially in that each connecting member 12, 14 comprises:
  • a first substantially parallelepipedal part 40, 40 'in which are formed the corresponding bore 13, 15 intended to cooperate with the operating rod 26 and a through-housing 41, 41 'into which the corresponding bore 13, 15 opens,
  • a second piece 42, 42 'on which are pivotally mounted the corresponding rods, the second piece 42, 42' having a non-threaded bore 43, 43 'for the passage of the operating rod 26, and being slidably mounted in the corresponding housing 41, 41 'delimited by the first corresponding piece 40, 40' in a direction parallel to the axis of the operating rod 26 between a first position in which the second piece 42, 42 'is brought closer to the other connecting member and a second position in which the second piece 42, 42 'is remote from the other link member, and
  • a helical spring 44, 44 ', mounted around the operating rod 26 and interposed between the first and second corresponding parts, arranged to urge the second piece 42, 42' in its first position.

Chaque extrémité du ressort hélicoïdal 44, 44' de chaque organe de liaison 12, 14 est de préférence engagée autour d'une bague 45, 45' montée autour de la tige de manoeuvre 26.Each end of the helical spring 44, 44 'of each connecting member 12, 14 is preferably engaged around a ring 45, 45' mounted around the operating rod 26.

Une telle structure de chaque organe de liaison 12, 14 assure un amortissement des chocs générés par le contact du tiroir avec le poussoir 5 lors de la fermeture du tiroir.Such a structure of each connecting member 12, 14 provides damping shocks generated by the contact of the drawer with the pusher 5 when closing the drawer.

Selon un mode de réalisation non représenté sur les figures, le poussoir 5 comporte un aimant permanent agencé pour coopérer avec la face arrière métallique du tiroir.According to an embodiment not shown in the figures, the pusher 5 comprises a permanent magnet arranged to cooperate with the metal rear face of the drawer.

Selon ce mode de réalisation, le fonctionnement du dispositif d'assistance est le suivant.According to this embodiment, the operation of the assistance device is as follows.

On supposera que les moyens de liaison sont dans leur position de fermeture et que le tiroir est en position fermée, c'est-à-dire que la face arrière du tiroir est au contact du poussoir.It will be assumed that the connecting means are in their closed position and the drawer is in the closed position, that is to say that the rear face of the drawer is in contact with the pusher.

Pour ouvrir le tiroir, un utilisateur doit exercer une pression sur la face avant du tiroir suffisante pour que le capteur de force 33 porté par le poussoir 5 détecte une force supérieure ou égale à la valeur prédéterminée. Dans ce cas, les moyens de contrôle commandent l'alimentation du moteur électrique 29 de telle sorte que ce dernier entraîne en rotation la tige de manoeuvre 26 dans le sens correspondant à un rapprochement des premier et second organes de liaison 12, 14. Il s'en suit un déplacement du poussoir 5 dans sa position d'ouverture et une éjection du tiroir vers sa position ouverte, cette éjection du tiroir étant possible du fait que la force d'attraction exercée par l'aimant permanent porté par le poussoir sur le tiroir est faible comparée à la force de poussée exercée par le poussoir 5 sur le tiroir lors du déplacement du poussoir vers sa position d'ouverture. Les moyens de contrôle commandent ensuite l'arrêt du moteur électrique 29 de manière à ce que le poussoir 5 reste dans sa position d'ouverture jusqu'à une fermeture ultérieure du tiroir.To open the drawer, a user must exert pressure on the front of the drawer sufficient for the force sensor 33 carried by the pusher 5 detects a force greater than or equal to the predetermined value. In this case, the control means control the power supply of the electric motor 29 so that the latter rotates the operating rod 26 in the direction corresponding to a bringing together of the first and second connecting members 12, 14. follows a movement of the pusher 5 in its open position and an ejection of the drawer to its open position, this ejection of the drawer being possible because the attraction force exerted by the permanent magnet carried by the pusher on the drawer is low compared to the force of thrust exerted by the pusher 5 on the drawer during movement of the pusher to its open position. The control means then control the stopping of the electric motor 29 so that the pusher 5 remains in its open position until a subsequent closure of the drawer.

Pour fermer le tiroir, l'utilisateur pousse ce dernier vers sa position fermée. Dès que le tiroir vient en contact avec l'élément d'amortissement 8 du poussoir 5, le tiroir est plaqué contre le poussoir du fait de la force d'attraction exercée par l'aimant permanent sur le tiroir et le capteur de force 33 détecte une force supérieure à la valeur prédéterminée. Les moyens de contrôle commandent alors l'alimentation du moteur électrique 29 de telle sorte que ce dernier entraîne en rotation la tige de manoeuvre 26 dans le sens correspondant à un éloignement des premier et second organes de liaison 12, 14. Il s'en suit un déplacement du poussoir 5 dans sa position de fermeture et un déplacement du tiroir dans sa position fermée du fait de la coopération entre l'aimant permanent porté par le poussoir et le tiroir. Une fois en position fermée, le tiroir est maintenu dans cette position du fait de cette coopération entre l'aimant permanent et le tiroir.To close the drawer, the user pushes the drawer to its closed position. As soon as the drawer comes into contact with the damping element 8 of the pusher 5, the drawer is pressed against the pusher because of the attraction force exerted by the permanent magnet on the drawer and the force sensor 33 detects a force greater than the predetermined value. The control means then control the supply of the electric motor 29 so that the latter rotates the operating rod 26 in the direction corresponding to a distance from the first and second connecting members 12, 14. It follows a displacement of the pusher 5 in its closed position and a displacement of the slide in its closed position due to the cooperation between the permanent magnet carried by the pusher and the slide. Once in the closed position, the drawer is held in this position because of this cooperation between the permanent magnet and the drawer.

Les figures 18 et 19 représentent un dispositif d'assistance selon un troisième mode de réalisation qui diffère de celui représenté sur les figures 13 à 17 essentiellement en ce que les troisième et quatrième bielles 22, 24 sont montées pivotantes respectivement sur les première et deuxième bielles 18, 20 autour d'axes de rotation 46, 47 décalés par rapport à l'axe de la tige de manoeuvre 26 et par rapport aux broches de rotations 16, 17.The Figures 18 and 19 represent an assistance device according to a third embodiment which differs from that shown in the Figures 13 to 17 essentially in that the third and fourth links 22, 24 are pivotally mounted respectively on the first and second connecting rods 18, 20 about axes of rotation 46, 47 offset from the axis of the operating rod 26 and relative to to the rotation spindles 16, 17.

L'axe de rotation 46 est matérialisé par deux ergots ménagés respectivement sur deux faces opposées de la première bielle 18, tandis que l'axe de rotation 47 est matérialisé par deux ergots ménagés respectivement sur deux faces opposées de la deuxième bielle 20.The axis of rotation 46 is embodied by two lugs respectively formed on two opposite faces of the first connecting rod 18, while the axis of rotation 47 is embodied by two lugs respectively formed on two opposite faces of the second connecting rod 20.

Le dispositif d'assistance selon l'invention permet, du fait de la conception des moyens de liaison en parallélogramme déformable et de la présence du capteur de force et des moyens de commande, d'éviter toute ouverture intempestive du tiroir et d'assurer :

  • une poussée sur le tiroir auto-adaptative selon la charge de ce dernier,
  • une poussée en n'importe quel point de la face arrière du tiroir avec un même degré d'efficacité, et
  • une poussée suivant un axe linéaire qui évite tout frottement sur le tiroir.
The assistance device according to the invention makes it possible, because of the design of the deformable parallelogram linkage means and the presence of the force sensor and the control means, to prevent any inadvertent opening of the drawer and to ensure:
  • a push on the self-adaptive drawer according to the load of the latter,
  • a push at any point on the back of the drawer with the same degree of efficiency, and
  • thrust along a linear axis that avoids any friction on the drawer.

Comme il va de soi, l'invention ne se limite pas aux seules formes d'exécution de ce dispositif d'assistance, décrites ci-dessus à titre d'exemples, elle en embrasse au contraire toutes les variantes de réalisation. C'est ainsi notamment que le support pourrait être monté coulissant sur un profilé vertical fixé à l'arrière du meuble ou sur une équerre de fixation fixée sur une portion latérale du meuble.As goes without saying, the invention is not limited to the embodiments of this assistance device, described above as examples, it encompasses all the variants. Thus, in particular, the support could be slidably mounted on a vertical section fixed to the back of the piece of furniture or on a fixing bracket fixed to a lateral portion of the piece of furniture.
