Description

L'invention concerne un mobilier de sécurité à tiroir susceptible de contenir des objets précieux à protéger contre les agressions extérieures telles que : le feu, les gaz, le vol..., mais devant être régulièrement utilisés.The invention relates to safety furniture with a drawer capable of containing precious objects to be protected against external aggressions such as: fire, gas, theft, but which must be regularly used.

On connait déjà (par exemple : demande de brevet européen EP-0 112 412, français FR-2 196 193, brevet français FR-1 154 183, et brevets américains US-2 118 382, US-2 145 314 et US-2 517 175), divers dispositifs de motorisation ou de rappel élastique des manoeuvres d'ouverture et de fermeture des tiroirs. De tels dispositifs, lorsqu'ils sont du type à fermeture automatique, obligent l'utilisateur ou une personne extérieure à actionner sur une pédale ou un contacteur de commande. De plus, dans le cas où le rappel est effectué par un moteur électrique actif sur toute la course de déplacement du tiroir, l'utilisation du dispositif implique une consommation en électricité importante, et il se peut que le dispositif soit laissé en position ouverte si les accumulateurs alimentant le moteur viennent à être déchargés ou si l'alimentation électrique est coupée. De plus, de tels dispositifs ne répondent pas aux normes de sécurité puisque le moteur ou le ressort de rappel est actif au moment précis de la fermeture du tiroir, alors que cette fermeture peut être gênée par des objets mal rangés, voire même des membres de l'utilisateur. En particulier, de tels dispositifs sont particulièrement dangereux pour l'utilisateur si la fermeture automatique intervient alors que celui-ci manipule les objets à l'intérieur du tiroir.We already know (for example: European patent application EP-0 112 412, French FR-2 196 193, French patent FR-1 154 183, and American patents US-2 118 382, US-2 145 314 and US-2 517 175), various motorization or elastic return devices for the opening and closing operations of the drawers. Such devices, when they are of the self-closing type, oblige the user or an outside person to actuate on a pedal or a control switch. In addition, in the case where the recall is carried out by an active electric motor over the entire travel of movement of the drawer, the use of the device involves a significant consumption of electricity, and it may be that the device is left in the open position the accumulators supplying the engine come to be discharged or if the electrical supply is cut. In addition, such devices do not meet safety standards since the motor or the return spring is active at the precise moment of closing the drawer, while this closing can be hampered by poorly stored objects, or even members of the user. In particular, such devices are particularly dangerous for the user if the automatic closing occurs while the latter is handling the objects inside the drawer.

Par ailleurs, les dispositifs connus sont fort complexes et mettent en jeu de nombreuses pièces mécaniques et électriques. De ce fait, lorsqu'un des éléments mécaniques ou électriques du dispositif vient à être défaillant, le tiroir devient inutilisable, et surtout n'est pas forcément en position fermée de sécurité.Furthermore, the known devices are very complex and involve many mechanical and electrical parts. Therefore, when one of the mechanical or electrical elements of the device becomes faulty, the drawer becomes unusable, and above all is not necessarily in the closed safety position.

Par ailleurs, la réparation de l'élément défectueux ou même la remise du dispositif à l'état normal après une utilisation dans des conditions d'urgence ou d'alerte peut nécessiter l'ouverture du tiroir. De ce fait, en cas de défaillance d'un de ces éléments, pendant tout le temps de la réparation ou de la maintenance, les objets contenus dans le tiroir ne sont pas protégés.Furthermore, repairing the defective element or even returning the device to its normal state after use in emergency or alert conditions may require the drawer to be opened. Therefore, in case of failure of one of these elements, during the entire repair or maintenance, the objects contained in the drawer are not protected.

On connait également, par exemple de la demande de brevet français 2 580 324 un mécanisme de fermeture et verrouillage automatiques pour armoire de sécurité anti-feu. Dans de tels mécanismes, les portes de l'armoire sont rappelées en position fermée/verrouillée par des moyens de rappel au cas où le feu viendrait à se déclarer. La détection du feu se fait grâce à des biellettes en matière thermo-fusible qui maintiennent normalement les portes en position ouverte. De tels mécanismes connus sont extrêmement sophistiqués et n'offrent pas en pratique une sécurité suffisante. En effet, il se peut que le feu détruise les objets contenus dans le mobilier, sans pour autant que les biellettes thermo-fusibles n'aient fondu. Il se peut également par ailleurs, que les biellettes thermo-fusibles viennent à fondre alors qu'aucun incendie ne se soit véritablement déclaré. Enfin, de tels mécanismes sont inefficaces pour des mobiliers de sécurité de protection des objets contre les gaz ou le vol.Also known, for example from French patent application 2,580,324, is an automatic closing and locking mechanism for a fire safety cabinet. In such mechanisms, the cabinet doors are recalled to the closed / locked position by return means in the event that a fire breaks out. Fire detection is carried out using rods made of heat-fusible material which normally hold the doors in the open position. Such known mechanisms are extremely sophisticated and do not offer sufficient security in practice. Indeed, it may be that the fire destroys the objects contained in the furniture, without the hot-melt links having melted. It is also possible, moreover, that the fusible links will melt when no fire has really started. Finally, such mechanisms are ineffective for security furniture for protecting objects against gas or theft.

Le brevet américain US-A- 2 145 314, ce dernier correspondant au préambule de la revendication 1, décrit un tiroir-caisse fonctionnant soit en mode normal dans lequel le tiroir est rappelé par un ressort en position fermée mais verrouillé/déverrouillé manuellement, soit en mode de sécurité dans lequel il est verrouillé à distance en cas d'agression et ne peut être déverrouillé qu'après un certain temps. Le tiroir n'est donc pas en permanence en position de sécurité, l'utilisateur ne peut pas détecter par un simple regard l'état du tiroir et ce tiroir n'est pas applicable à un mobilier anti-feu ou de protection contre les agressions chimiques.American patent US-A-2 145 314, the latter corresponding to the preamble of claim 1, describes a cash drawer operating either in normal mode in which the drawer is recalled by a spring in the closed position but manually locked / unlocked, or in security mode in which it is locked remotely in the event of an attack and can only be unlocked after a certain time. The drawer is therefore not permanently in the safety position, the user cannot detect the state of the drawer at a glance and this drawer is not applicable to fire-fighting or protection against attack furniture chemicals.

L'invention vise à remédier aux inconvénients précités des mobiliers de sécurité, et a pour objet de proposer un tel mobilier à tiroir pour lequel le tiroir est obligatoirement et en permanence en position fermée/vérrouillée sauf si l'utilisateur l'utilise effectivement et le maintient en position ouverte, et qui donc est en permanence et systématiquement à l'état de sécurité dans lequel il protège effectivement les objets qu'il contient.The invention aims to remedy the aforementioned drawbacks of furniture safety, and aims to provide such a drawer furniture for which the drawer is necessarily and permanently in the closed / locked position unless the user actually uses it and keeps it in the open position, and which is therefore permanently and systematically in the security state in which it effectively protects the objects it contains.

L'invention a simultanément pour objet de proposer un tel mobilier qui soit d'une sécurité totale d'utilisation, et notamment qui ne puisse pas détériorer les objets ou blesser l'utilisateur lors de la manoeuvre de fermeture automatique.The invention simultaneously aims to provide such furniture which is completely safe to use, and in particular which cannot damage the objects or injure the user during the automatic closing maneuver.

Un autre objet de l'invention est de proposer un tel mobilier qui ne consomme que peu d'énergie électrique, et qui soit en position fermée en cas de défaillance de l'alimentation électrique.Another object of the invention is to provide such furniture which consumes little electrical energy, and which is in the closed position in the event of failure of the electrical supply.

Un autre objet de l'invention est de proposer un tel mobilier qui protège les objets qu'il contient du feu ou des agressions chimiques liquides ou gazeuses.Another object of the invention is to provide such furniture which protects the objects it contains from fire or liquid or gaseous chemical attack.

Le mode de réalisation préférentiel représenté sur les figures d'un mobilier 1 selon l'invention est un coffre ignifuge parallélépipédique comportant un tiroir 1 coulissant perpendiculairement à l'une des faces du mobilier 1 dénommée conventionnellement face avant 3.The preferred embodiment represented in the figures of a piece of furniture 1 according to the invention is a rectangular fireproof chest comprising a drawer 1 sliding perpendicularly to one of the faces of the piece of furniture 1 conventionally called the front face 3.

Le coffre 1 comporte cinq autres faces dénommées également de façon conventionnelle faces arrière 4, latérale gauche 5, latérale droite 6, de dessus 7, de dessous 8.The trunk 1 has five other faces also conventionally called rear faces 4, left side 5, right side 6, from above 7, from below 8.

Le tiroir 2 comporte une paroi avant 9 munie d'une poignée 10 et au moins un élément 11 formant contenant s'étendant vers l'arrière à partir de la paroi verticale avant 9 du tiroir 2.The drawer 2 comprises a front wall 9 provided with a handle 10 and at least one element 11 forming a container extending rearwards from the front vertical wall 9 of the drawer 2.

Le coffre 1 forme châssis 12 pour le tiroir 2 qui est monté coulissant sur ce châssis 12 grâce à des moyens 13 de guidage qui sont par exemple constitués de glissières, roulettes...The trunk 1 in the form of a chassis 12 for the drawer 2 which is slidably mounted on this chassis 12 by means of guide means 13 which for example consist of slides, rollers, etc.

Les éléments précités d'un mobilier 1 selon l'invention sont largement connus de l'homme du métier en eux-mêmes, et peuvent faire l'objet de nombreuses variantes évidentes. Par exemple, le mobilier peut être constitué d'un bureau, ou d'une armoire, le tiroir 2 peut être du type horizontal, vertical ou incliné, peut coulisser horizontalement, verticalement, ou selon une direction inclinée, peut être du type simple ou double extension, ... Par ailleurs, le coffre 1 tel que représenté peut également faire partie intégrante d'un mobilier plus général, par exemple être inséré dans une armoire anti feu, ou encore être inséré rigidement et de façon inamovible dans les murs d'un bâtiment. Dans le cadre de la présente description, le terme "position" désigne non seulement un état fonctionnel du tiroir 2, mais aussi une position effective du tiroir 2 par rapport au châssis 12. Le mobilier 1 de sécurité pour objets précieux, selon l'invention, comportant un châssis 12, un tiroir 2 monté coulissant horizontalement sur ce châssis 12 grace aux moyens 13 de guidage, est caractérisé en ce qu'il comporte :

  • des moyens 14 non-motorisés de rappel du tiroir 2 à partir de toute position ouverte dans laquelle l'intérieur 15 du tiroir 2 est accessible, vers une position fermée/déverrouillée dans laquelle l'intérieur 15 du tiroir 2 est entièrement occulté et à partir de laquelle le tiroir 2 peut être tiré manuellement en position ouverte à l'encontre des moyens 14 de rappel, ces moyens 14 de rappel étant actifs pour rappeler le tiroir 2 en position fermée/déverrouillée dès qu'il est relâché à partir de toute position ouverte,
  • des moyens 16 motorisés de verrouillage/déverrouillage actifs entre la position fermée/déverrouillée et une position fermée/verrouillée à partir de laquelle le tiroir 2 ne peut plus être ouvert manuellement, ces moyens 16 motorisés de verrouillage/déverrouillage rappelant automatiquement et systématiquement le tiroir 2 en position fermée/verrouillée,
  • des moyens 17 de commande du déverrouillage qui, lorsqu'ils sont actionnés dans la position fermée /verrouillée du tiroir 2, déclenchent le déverrouillage du tiroir 2 et sa mise en position fermée/déverrouillée par les moyens 16 motorisés de verrouillage/ déverrouillage.
The aforementioned elements of furniture 1 according to the invention are widely known to those skilled in the art in themselves, and can be the subject of many obvious variants. For example, the furniture can consist of a desk, or a cabinet, the drawer 2 can be of the horizontal, vertical or inclined type, can slide horizontally, vertically, or in an inclined direction, can be of the simple type or double extension, ... Furthermore, the trunk 1 as shown can also be an integral part of more general furniture, for example being inserted in a fire-resistant cabinet, or even being rigidly and irremovably inserted in the walls of 'a building. In the context of the present description, the term "position" designates not only a functional state of the drawer 2, but also an effective position of the drawer 2 relative to the chassis 12. The security furniture 1 for precious objects, according to the invention , comprising a chassis 12, a drawer 2 mounted to slide horizontally on this chassis 12 by means of the guide means 13, is characterized in that it comprises:
  • non-motorized means 14 for returning the drawer 2 from any open position in which the interior 15 of the drawer 2 is accessible, to a closed / unlocked position in which the interior 15 of the drawer 2 is completely obscured and from from which the drawer 2 can be pulled manually in the open position against the return means 14, these return means 14 being active to return the drawer 2 to the closed / unlocked position as soon as it is released from any position opened,
  • motorized locking / unlocking means 16 active between the closed / unlocked position and a closed / locked position from which the drawer 2 can no longer be opened manually, these motorized locking / unlocking means 16 automatically and systematically recalling the drawer 2 in closed / locked position,
  • means 17 for controlling the unlocking which, when they are actuated in the closed / locked position of the drawer 2, trigger the unlocking of the drawer 2 and its setting into the closed / unlocked position by the motorized means 16 for locking / unlocking.

Le châssis 12 définit un encadrement 18 pour la paroi avant 9 du tiroir 2. En position fermée/verrouillée (figure 1), la paroi avant 9 est complètement encastrée dans l'encadrement 18, et la face avant extérieure verticale 19 de la paroi 9 du tiroir 2 vient affleurer la face avant 3 du mobilier 1 ; les chants périphériques 20 de cette paroi 9 étant invisibles.The frame 12 defines a frame 18 for the front wall 9 of the drawer 2. In the closed / locked position (FIG. 1), the front wall 9 is completely embedded in the frame 18, and the vertical outer front face 19 of the wall 9 of the drawer 2 is flush with the front face 3 of the furniture 1; the peripheral edges 20 of this wall 9 being invisible.

Dans cette position fermée/verrouillée, les objets contenus à l'intérieur 15 du mobilier 1 sont parfaitement protégés contre les agressions extérieures. Par exemple, dans le cas d'un coffre 1 ignifuge, les joints de protection assurant l'herméticité totale du tiroir 2 sont comprimés et actifs.In this closed / locked position, the objects contained inside 15 of the furniture 1 are perfectly protected against external aggressions. For example, in the case of a fire-retardant chest 1, the protective seals ensuring the total tightness of the drawer 2 are compressed and active.

La paroi avant 9 verticale du tiroir 2 est épaisse et comporte des chants périphériques 20 plans s'étendant de préférence sur toute l'épaisseur de cette paroi 9. La paroi 9 peut être constituée de plusieurs couches de matériaux différents en fonction des applications de l'invention. Cependant, les chants phériphériques 20 de cette paroi 9 ne comportent aucun rebord ou épaulement susceptible de venir à recouvrement de la face avant 3 du mobilier 1. La paroi 9 peut comporter, si nécessaire, une feuillure interne.The vertical front wall 9 of the drawer 2 is thick and has peripheral edges 20 planes preferably extending over the entire thickness of this wall 9. The wall 9 may consist of several layers of different materials depending on the applications of the 'invention. However, the peripheral edges 20 of this wall 9 do not have any rim or shoulder capable of coming to overlap the front face 3 of the furniture 1. The wall 9 can comprise, if necessary, an internal rebate.

Cependant, dans le mode de réalisation préférentiel représenté, la paroi 9 ne comporte pas de feuillure interne, mais a au contraire la forme d'un parallélépipède rectangle, et les chants périphériques 20 s'étendent sur toute son épaisseur. Le châssis 12 comporte une feuillure interne 21 contre laquelle la paroi 9 est plaquée en position fermée/verrouillée. Les joints éventuels sont insérés entre cette feuillure 21 et la paroi 9 du tiroir 2.However, in the preferred embodiment shown, the wall 9 does not have an internal rebate, but on the contrary has the shape of a rectangular parallelepiped, and the peripheral edges 20 extend over its entire thickness. The chassis 12 has an internal rebate 21 against which the wall 9 is pressed in the closed / locked position. Any seals are inserted between this rebate 21 and the wall 9 of the drawer 2.

En position fermée/déverrouillée (figure 2) distincte de la position fermeé/verrouillée, la paroi avant 9 du tiroir 2 saille de la face avant 3 du mobilier 1 tout en occultant l'intérieur 15 du tiroir 2 et en ne laissant apparentes que la face avant 19 et une partie plane des chants périphériques 20 de cette paroi 9. Ainsi, aucun coincement d'objets ou de membres entre l'encadrement 18 et la paroi 9 du tiroir 2 n'est possible dans ou à partir de cette position fermée/déverrouillée.In the closed / unlocked position (FIG. 2) distinct from the closed / locked position, the front wall 9 of the drawer 2 projects from the front face 3 of the furniture 1 while obscuring the interior 15 of the drawer 2 and leaving only visible the front face 19 and a flat part of the peripheral edges 20 of this wall 9. Thus, no jamming of objects or members between the frame 18 and the wall 9 of the drawer 2 is possible in or from this closed position / unlocked.

Par contre, le fait que la paroi 9 du tiroir 2 saille à l'extérieur par rapport à la face avant 3 du mobilier 1, permet à l'utilisateur de savoir d'un simple regard que le tiroir 2 est en position fermée/déverrouillée, et donc qu'il peut être ouvert.By cons, the fact that the wall 9 of the drawer 2 protrudes outside relative to the front face 3 of the furniture 1, allows the user to know at a glance that the drawer 2 is in the closed / unlocked position , and therefore that it can be opened.

Une position ouverte du tiroir 2 est représentée en figure 3. Dans cette position ouverte, l'intérieur 15 est accessible. Cependant, les moyens 16 motorisés de verrouillage/déverrouillage sont inactifs. Les moyens 16 motorisés de verrouillage/déverrouillage ne sont actifs qu'à partir des positions fermée/déverrouillée ou fermée/verrouillée. Ainsi, en position ouverte, l'utilisateur peut utiliser et manipuler le tiroir 2 et les objets qu'il contient en toute sécurité, et sans risque de voir ce tiroir 2 se refermer brusquement ou de façon intempestive.An open position of the drawer 2 is shown in FIG. 3. In this open position, the interior 15 is accessible. However, the motorized locking / unlocking means 16 are inactive. The motorized locking / unlocking means 16 are only active from the closed / unlocked or closed / locked positions. Thus, in the open position, the user can use and manipulate the drawer 2 and the objects it contains safely, and without the risk of seeing this drawer 2 close suddenly or inadvertently.

Au contraire, dans toute position ouverte, les moyens 14 non-motorisés de rappel du tiroir sont actifs, de sorte que ce tiroir 2 est rappelé en position fermée/déverrouillée (figure 2) dès que l'utilisateur lâche le tiroir 2. Les moyens 14 non-motorisés de rappel sont des moyens contre lesquels il est aisé d'agir en tirant le tiroir 2. De plus, ces moyens 14 sont conçus de telle sorte, que l'arrêt du tiroir en toute position ouverte est possible à volonté. Ainsi, si un objet ou un membre de l'utilisateur vient à être coincé entre le châssis 12 et le tiroir 2, ce tiroir 2 restera en position ouverte. C'est là le seul cas de figure accidentel dans lequel le tiroir 2 ne revient pas en position fermée/verrouillée.On the contrary, in any open position, the non-motorized means 14 for returning the drawer are active, so that this drawer 2 is returned to the closed / unlocked position (FIG. 2) as soon as the user releases the drawer 2. The non-motorized return means 14 are means against which it is easy to act by pulling the drawer 2. In addition, these means 14 are designed so that stopping the drawer in any open position is possible at will. Thus, if an object or a member of the user is trapped between the frame 12 and the drawer 2, this drawer 2 will remain in the open position. This is the only accidental scenario in which the drawer 2 does not return to the closed / locked position.

Cependant, un tel cas de figure est infiniment peu probable, dans la mesure où l'élément 11 formant contenant du tiroir peut être conformé de façon à empêcher au maximum toute saillie des objets qu'il contient en dehors de l'intérieur 15 qu'il délimite. Les moyens 14 non-motorisés de rappel sont suffisamment doux pour éviter toute blessure de l'utilisateur au cas où ses doigts viendraient accidentellement à être coincés entre la paroi 9 du tiroir 2 et l'encadrement 18.However, such a scenario is extremely unlikely, insofar as the element 11 forming the drawer container can be shaped so as to prevent as much as possible any protrusion of the objects which it contains outside the interior 15 that it delimits. The non-motorized return means 14 are gentle enough to avoid any injury to the user in the event that his fingers accidentally get caught between the wall 9 of the drawer 2 and the frame 18.

Par exemple, les moyens 14 de rappel comprennent un organe élastique 14 de traction de grande longueur qui s'étend lors de l'ouverture du tiroir 2.For example, the return means 14 comprise an elastic traction member 14 of great length which extends when the drawer 2 is opened.

La figure 5 représente une forme de réalisation possible de ces moyens 14 non-motorisés de rappel. L'organe élastique 14 de traction est constitué d'un ressort de traction 14 de grande longueur dont une extrémité 22 est solidaire du châssis 12, tandis que l'autre extrémité 23 est associée rigidement à une corde 24 qui est reliée à son autre extrémité à l'arrière de l'élément 11, formant contenant du tiroir 2. Le ressort 14 est associé à et monté sur une paroi verticale arrière 25 percée d'un trou 26 à travers lequel la corde 24 passe. Des galets 27 maintiennent le ressort 14 contre la paroi 25, tout en autorisant son extension.FIG. 5 represents a possible embodiment of these non-motorized return means 14. The elastic traction member 14 consists of a very long tension spring 14, one end 22 of which is integral with the chassis 12, while the other end 23 is rigidly associated with a rope 24 which is connected at its other end at the rear of the element 11, forming a container for the drawer 2. The spring 14 is associated with and mounted on a rear vertical wall 25 pierced with a hole 26 through which the cord 24 passes. Rollers 27 hold the spring 14 against the wall 25, while allowing its extension.

Les moyens 14 de rappel peuvent cependant être constitués, en variante, soit d'une simple inclinaison des moyens 13 de guidage vers le bas et vers l'arrière du mobilier 1, soit d'un poids levé lors de l'ouverture du tiroir 2, ce poids étant relié de façon appropriée par des poulies et par une corde à l'arrière du tiroir 2. D'autres variantes sont encore possibles (vérin pneumatique, hydraulique,...).The return means 14 may however consist, alternatively, either of a simple inclination of the means 13 for guiding downwards and rearwards of the furniture 1, or of a weight lifted when the drawer 2 is opened , this weight being appropriately connected by pulleys and by a rope at the rear of the drawer 2. Other variants are still possible (pneumatic, hydraulic cylinder, etc.).

Les moyens 16 motorisés de verrouillage/déverrouillage sont de préférence électriques et comportent un moteur électrique 28 à courant continu, des accumulateurs 29 fournissant l'énergie électrique au moteur 28, un dispositif chargeur/redresseur 30 permettant de recharger les accumulateurs 29 et/ou d'alimenter le moteur électrique 28 à partir du secteur par l'intermédiaire d'une prise extérieure 31, des contacteurs de fin de course 33, 34, de position 35 du tiroir 2, un train d'engrenages 36 de transmission coopérant avec l'arbre du moteur 28 et comprenant un arbre de sortie 37, et un relais inverseur de polarités 38 contrôlant l'alimentation du moteur 28.The motorized locking / unlocking means 16 are preferably electric and comprise a direct current electric motor 28, accumulators 29 supplying electrical energy to the motor 28, a charger / rectifier device 30 making it possible to recharge the accumulators 29 and / or d 'power the electric motor 28 from the sector via an external socket 31, limit switches 33, 34, position 35 of the drawer 2, a gear train 36 of transmission cooperating with the motor shaft 28 and comprising an output shaft 37, and a polarity reversing relay 38 controlling the supply of motor 28.

Selon l'invention, le mobilier 1 comporte un dispositif de temporisation 39 actif sur les moyens 16 motorisés de verrouillage/déverrouillage de sorte que, après écoulement du temps To de temporisation, les moyens 16 motorisés de verrouillage/déverrouillage rappellent systématiquement le tiroir 2 en position fermée/verrouillée à partir de la position fermée/déverrouillée. Ainsi, si le tiroir 2 passe dans la position fermée/déverrouillée et si le temps To de temporisation est écoulé, le tiroir 2 sera rappelé automatiquement et systématiquement en position fermée/verrouillée par les moyens 16 motorisés de verrouillage/déverrouillage. De préférence, le dispositif de temporisation 39 est déclenché par actionnement sur les moyens 17 de commande du déverrouillage. Dans ce cas, le temps To de la temporisation est bien entendu supérieur au temps nécessaire pour la mise en place du tiroir 2 en position fermée/déverrouillée par les moyens 16 de verrouillage/déverrouillage. Grâce à cette temporisation, si le tiroir 2 reste en position fermée/déverrouillée sans être ouvert, il sera automatiquement replacé en position fermée/verrouillée. Au contraire, si le tiroir 2 est placé en position ouverte par l'utilisateur, les moyens 16 de verrouillage/ déverrouillage deviennent inactifs, mais le temps de temporisation continue à s'écouler. Ainsi, lorsque l'utilisateur relâchera le tiroir 2, celui-ci repassant en position fermée/déverrouillée, le temps To de temporisation sera généralement écoulé, et le tiroir sera immédiatement placé en position fermée/verrouillée par les moyens 16 motorisés de verrouillage/déverrouillage. Ainsi, le mobilier selon l'invention est en permanence et systématiquement à l'état de sécurité, et ne nécessite aucune action extérieure en cas d'alerte.According to the invention, the furniture 1 comprises a time delay device 39 active on the motorized means 16 for locking / unlocking so that, after the time delay To has elapsed, the motorized means 16 for locking / unlocking systematically recall the drawer 2 by closed / locked position from closed / unlocked position. Thus, if the drawer 2 goes into the closed / unlocked position and if the time delay To has elapsed, the drawer 2 will be automatically and systematically recalled to the closed / locked position by the motorized means 16 for locking / unlocking. Preferably, the time delay device 39 is triggered by actuation on the unlocking control means 17. In this case, the time To of the time delay is of course greater than the time necessary for the introduction of the drawer 2 in the closed / unlocked position by the locking / unlocking means 16. With this time delay, if the drawer 2 remains in the closed / unlocked position without being opened, it will automatically be returned to the closed / locked position. On the contrary, if the drawer 2 is placed in the open position by the user, the locking / unlocking means 16 become inactive, but the time delay continues to elapse. Thus, when the user releases the drawer 2, the latter going back to the closed / unlocked position, the time delay To will generally be over, and the drawer will be immediately placed in the closed / locked position by the motorized means 16 for locking / unlocking. . Thus, the furniture according to the invention is permanently and systematically in a safe state, and does not require any external action in the event of an alert.

De préférence, le dispositif de temporisation 39 est inclus dans le relais inverseur de polarités 38 qui est temporisé. Le temps To de temporisation est avantageusement compris entre 2 et 15, notamment de l'ordre de 8 secondes.Preferably, the timing device 39 is included in the polarity reversing relay 38 which is timing. The time delay To is advantageously between 2 and 15, in particular of the order of 8 seconds.

Selon l'invention, le mobilier 1 comporte un boîtier 40 électrique associé rigidement mais de façon amovible au châssis 12, et qui contient l'ensemble des dispositifs électriques nécessaires au fonctionnement du mobilier 1, notamment les moyens 16 motorisés de verrouillage/déverrouillage, les accumulateurs 29 et les moyens 17 de commande du déverrouillage.According to the invention, the furniture 1 comprises an electrical box 40 rigidly but removably associated with the chassis 12, and which contains all of the electrical devices necessary for the operation of the furniture 1, in particular the motorized means 16 for locking / unlocking, the accumulators 29 and the unlocking control means 17.

Ce boîtier 40 est par exemple réalisé en tôle pliée. Il forme une platine de support pour le moteur 28, le train d'engrenages 36, les différents contacteurs 33, 34, 35, le relais 38, les accumulateurs 29, le dispositif chargeur/redresseur 30, les moyens de commande 17, la prise de connexion électrique 31. Il supporte également sur sa face avant 41, outre les moyens de commande 17 et la prise électrique 31, un voyant lumineux 42 indiquant la mise à l'état actif du dispositif chargeur/redresseur 30, et des moyens 43 à serrure formant interrupteur général de l'alimentation électrique du moteur 28 par les accumulateurs 29 et/ou le dispositif chargeur/redresseur 30. Le boîtier 40 supporte également une butée de fin de course 44 du déverrouillage, et une butée de fin de course 45 du verrouillage associées respectivement au voisinage des contacteurs de fin de course 33 de déverrouillage, et 34 de verrouillage pour protéger ces contacteurs.This housing 40 is for example made of folded sheet. It forms a support plate for the motor 28, the gear train 36, the various contactors 33, 34, 35, the relay 38, the accumulators 29, the charger / rectifier device 30, the control means 17, the socket of electrical connection 31. It supports also on its front face 41, in addition to the control means 17 and the electrical outlet 31, an indicator light 42 indicating that the charger / rectifier device 30 is in the active state, and means 43 with lock forming a general switch of the electrical supply to the motor 28 by the accumulators 29 and / or the charger / rectifier device 30. The housing 40 also supports an end of travel stop 44 for unlocking, and a end travel stop 45 for locking associated respectively with the vicinity of the contactors limit switch 33 for unlocking, and 34 for locking to protect these contactors.

Le boîtier 40 est inséré dans un logement latéral correspondant 46 formé dans le châssis 12 et débouchant sur la face avant 3 du coffre 1. Lorsque le boîtier 40 est en place dans le logement 46, sa face avant 41 affleure et vient en prolongement de la face avant 3 du coffre 1. Le boîtier 40 est bloqué encastré dans le logement 46 du chassis 12 par des moyens d'association amovible, par exemple un dispositif 47 à serrure, solidaire de la face latérale gauche 5 du coffre 1. Ce dispositif 47 à serrure comporte par exemple un pène rotatif qui vient coopérer avec une gâche solidaire de la paroi latérale du boîtier 40. Le logement 46 comporte par ailleurs des moyens de guidage et de support du boîtier 40 facilitant son insertion et son extraction et assurant son maintien dans le logement 46. Ces moyens de guidage et de support sont de préférence simplement constitués de plaques ou glissières solidaires du châssis 12.The housing 40 is inserted into a corresponding lateral housing 46 formed in the chassis 12 and opening onto the front face 3 of the boot 1. When the housing 40 is in place in the housing 46, its front face 41 is flush and comes in extension of the front face 3 of the trunk 1. The box 40 is locked embedded in the housing 46 of the chassis 12 by removable association means, for example a device 47 with lock, integral with the left lateral face 5 of the trunk 1. This device 47 with lock comprises for example a rotary bolt which comes to cooperate with a keeper integral with the side wall of the housing 40. The housing 46 also comprises means for guiding and supporting the housing 40 facilitating its insertion and extraction and ensuring its maintenance in the housing 46. These guide and support means are preferably simply made up of plates or slides integral with the chassis 12.

Le schéma électrique de fonctionnement est représenté sur la figure 8. Les accumulateurs 29, par exemple constitués de huit éléments de 1,2 V/1,2 Ah au cadnium-nickel, sont connectés en sortie et en paralléle du dispositif chargeur/redresseur 30. Le voyant lumineux 42 est associé à ce dispositif 30 pour indiquer son fonctionnement. Un fusible 48 est également avantageusement associé au dispositif 30 chargeur/redresseur. La prise 31 permet d'alimenter le dispositif 30 chargeur/redresseur en courant alternatif 220 V, 50 Hz. Le dispositif interrupteur à serrure 47 est monté en série à la borne positive de sortie 49 du dispositif chargeur/redresseur 30. Le dispositif de temporisation 39 comporte avantageusement un condensateur 51, une résistance 52, et un transistor 53. Ce dispositif de temporisation 39 est commandé par le bouton poussoir 17 formant les moyens de commande du déverrouillage. Le dispositif 39 de temporisation commande le relais 38 inverseur de polarités. Sur le schéma, ce relais 38 d'alimentation du moteur 28 est représenté deux fois pour indiquer comment l'inversion de polarités est commandée par le dispositif 39 de temporisation, et comment par ailleurs, ce relais 38 est actionné par le bouton poussoir 17 de commande du déverrouillage, et permet d'alimenter le moteur 28.The electrical operating diagram is shown in FIG. 8. The accumulators 29, for example made up of eight elements of 1.2 V / 1.2 Ah with cadnium-nickel, are connected at the output and in parallel of the charger / rectifier device 30 The indicator light 42 is associated with this device 30 to indicate its operation. A fuse 48 is also advantageously associated with the device 30 charger / rectifier. The socket 31 makes it possible to supply the charger / rectifier device 30 with alternating current 220 V, 50 Hz. The lock switch device 47 is mounted in series at the positive output terminal 49 of the charger / rectifier device 30. The timing device 39 advantageously comprises a capacitor 51, a resistor 52, and a transistor 53. This timing device 39 is controlled by the push button 17 forming the unlocking control means. The timing device 39 controls the relay 38 for reversing polarities. In the diagram, this relay 38 for supplying the motor 28 is shown twice to indicate how the reversal of polarities is controlled by the timing device 39, and how, moreover, this relay 38 is actuated by the push button 17 of unlocking command, and enables the motor 28 to be powered.

Sur la figure 8, le relais 38 formant quatre interrupteurs 54, 55, 56, 57, est représenté dans son état initial, c'est-à-dire correspondant à la position fermée/verrouillée, le bouton poussoir 17 n'étant pas actionné. Lorsque l'on enfonce ce bouton poussoir 17, après avoir mis le dispositif en service gr̂ace à l'interrupteur à serrure 47, le bouton poussoir 17 déclenche la temporisation 39. Simultanément, le bouton poussoir 17 ferme l'interrupteur 54 connecté à la borne négative 50, et en série au contacteur de fin de course de déverrouillage 33 ; ouvre l'interrupteur 55 connecté à la borne positive 49, et en série avec le contacteur de fin de course de verrouillage 34, ces deux contacteurs 33, 34 étant reliés en parallèle à une borne commune 58 du moteur 28 ; ouvre l'interrupteur 57 connecté à la borne négative 50, et en série au contacteur de positionnement 35 ; et ferme l'interrupteur 56 connecté à la borne positive 49, et en parallèle avec le contacteur de position 35 à l'autre borne d'alimentation 59 du moteur 28.In FIG. 8, the relay 38 forming four switches 54, 55, 56, 57, is shown in its initial state, that is to say corresponding to the closed / locked position, the push button 17 not being actuated . When this push button 17 is pressed, after having put the device into service thanks to the lock switch 47, the push button 17 triggers the time delay 39. Simultaneously, the push button 17 closes the switch 54 connected to the terminal negative 50, and in series with the unlocking limit switch 33; opens the switch 55 connected to the positive terminal 49, and in series with the locking limit switch 34, these two contactors 33, 34 being connected in parallel to a common terminal 58 of the motor 28; opens the switch 57 connected to the negative terminal 50, and in series with the positioning switch 35; and closes the switch 56 connected to the positive terminal 49, and in parallel with the position switch 35 to the other supply terminal 59 of the motor 28.

Ces quatre interrupteurs 54, 55, 56, 57, du relais 38 restent dans le même état jusqu'à ce que la temporisation 39 commande le relais 38, ce qui a pour effet de remettre ces interrupteurs 54, 55, 56, 57, dans leur état initial tels que représentés.These four switches 54, 55, 56, 57 of the relay 38 remain in the same state until the time delay 39 controls the relay 38, which has the effect of resetting these switches 54, 55, 56, 57, in their initial state as shown.

Lorsque le tiroir 2 est en position fermée/déverrouillée, le contacteur de position 35 se ferme. Lorsque l'arbre de sortie 37 arrive en fin de déverrouillage, le contacteur 33 correspondant s'ouvre. De même, lorsque l'arbre 37 de sortie arrive en fin de verrouillage, le contacteur correspondant 34 s'ouvre. Ces différents contacteurs 33, 34, 35, sont rappelés dans leur position initiale telle que représentée par des ressorts.When the slide 2 is in the closed / unlocked position, the position switch 35 closes. When the output shaft 37 reaches the end of unlocking, the corresponding contactor 33 opens. Likewise, when the output shaft 37 reaches the end of locking, the corresponding contactor 34 opens. These different contactors 33, 34, 35 are returned to their initial position as shown by springs.

Il est clair à la lecture du schéma de la figure 8, que dans l'état représenté des interrupteurs 54, 55, 56, 57, la borne 58 du moteur est reliée à la borne positive 49, tandis que l'autre borne 59 du moteur est reliée à la borne négative 50 si le contacteur de position 35 est fermé. Dans cet état d'alimentation le moteur 28 tourne dans le sens du verrouillage jusqu'à ce que le contacteur 34 de fin de verrouillage s'ouvre.It is clear from reading the diagram in FIG. 8, that in the represented state of the switches 54, 55, 56, 57, the terminal 58 of the motor is connected to the positive terminal 49, while the other terminal 59 of the motor is connected to the negative terminal 50 if the position switch 35 is closed. In this supply state, the motor 28 rotates in the locking direction until the end of locking contactor 34 opens.

Au contraire, dans l'autre état de ces interrupteurs 54, 55, 56, et 57, la borne 58 du moteur 28 est reliée à la borne négative 50 via l'interrupteur 54, et l'autre borne 59 du moteur est reliée à la borne positive 49 via l'interrupteur 56. Dans cet état d'alimentation le moteur 28 tourne dans le sens du déverrouillage jusqu'à ce que le connecteur 33 de fin de déverrouillage s'ouvre.On the contrary, in the other state of these switches 54, 55, 56, and 57, the terminal 58 of the motor 28 is connected to the negative terminal 50 via the switch 54, and the other terminal 59 of the motor is connected to the positive terminal 49 via the switch 56. In this supply state, the motor 28 rotates in the unlocking direction until the connector 33 for ending the unlocking opens.

L'arbre de sortie 37 du train d'engrenages 36 comporte une tige 60 associée rigidement transversalement à cet arbre 37 et qui coopére avec les contacteurs 33, 34 de fin de course, et avec les butées 44, 45. Cet arbre de sortie 37 est disposé de façon à s'étendre latéralement vers l'intérieur du coffre 1, c'est-à-dire vers la droite si le logement 46 est situé à gauche du tiroir 2 comme représenté, pour coopérer avec un dispositif 61 de transmission. Ce dispositif 61 de transmission commande au moins une fourchette 62 de verrouillage/déverrouillage associée au châssis 12 pivotante par rapport à un axe 63 horizontal, transversal, et venant coopérer avec un goujon 64 horizontal, transversal solidaire du tiroir 2. Le dispositif 61 de transmission comporte pour ce faire, un arbre 65 supérieur horizontal, transversal dont une extrémité libre 66 coopére avec l'arbre de sortie 37 du train d'engrenages 36 solidaire du boîtier 40.The output shaft 37 of the gear train 36 comprises a rod 60 rigidly associated transversely with this shaft 37 and which cooperates with the limit switches 33, 34, and with the stops 44, 45. This output shaft 37 is arranged so as to extend laterally towards the inside of the boot 1, that is to say to the right if the housing 46 is located to the left of the drawer 2 as shown, to cooperate with a transmission device 61. This transmission device 61 controls at least one locking / unlocking fork 62 associated with the chassis 12 pivoting with respect to a horizontal, transverse axis 63 and coming to cooperate with a horizontal, transverse stud 64 secured to the drawer 2. The transmission device 61 to do this, comprises a horizontal, transverse upper shaft 65, one free end 66 of which cooperates with the output shaft 37 of the gear train 36 secured to the housing 40.

L'arbre de sortie 37 entraîne l'arbre de transmission 65 en rotation. Cependant, lorque le tiroir 2 est en position fermée/verrouillée, l'arbre de sortie 37 peut être dissocié de l'arbre de transmission 65 du dispositif 61 de transmission. Pour ce faire, l'arbre de sortie 37 du train d'engrenages 36 comporte avantageusement un méplat qui est engagé dans une fente radiale 67 de l'extrémité libre 66 de l'arbre de transmission 65, cette fente radiale 67 s'étendant sensiblement horizontalement lorsque le tiroir 2 est en position fermée/verrouillée. Une autre fente radiale, verticale 68, en position fermée/verrouillée, est prévue à l'extrémité libre 66 de l'arbre de transmission 65 pour la tige 60 de l'arbre de sortie 37. L'arbre de transmission 65 est monté en rotation par rapport au châssis 12 grâce à des paliers supports 69. L'arbre de transmission 65 commande le mouvement de chaque fourchette 62 (figures 7a, 7b), par l'intermédiaire d'une biellette 70 solidaire en rotation de l'arbre de transmission 65, et d'une bielle 71 de connexion articulée par l'une de ses extrémités à l'extrémité libre de la biellette 70 par un axe d'articulation 72. La bielle 71 est articulée à son autre extrémité la fourchette 62 par un axe 73 d'articulation éloigné de l'axe 63 de pivotement de cette fourchette 62.The output shaft 37 drives the transmission shaft 65 in rotation. However, when the drawer 2 is in the closed / locked position, the output shaft 37 can be separated from the transmission shaft 65 of the transmission device 61. To do this, the output shaft 37 of the gear train 36 advantageously comprises a flat which is engaged in a radial slot 67 of the free end 66 of the transmission shaft 65, this radial slot 67 extending substantially horizontally when the drawer 2 is in the closed / locked position. Another radial, vertical slot 68, in the closed / locked position, is provided at the free end 66 of the transmission shaft 65 for the rod 60 of the output shaft 37. The transmission shaft 65 is mounted in rotation relative to the chassis 12 by means of support bearings 69. The transmission shaft 65 controls the movement of each fork 62 (FIGS. 7a, 7b), by means of a link 70 integral in rotation with the shaft of transmission 65, and a connecting rod 71 articulated by one of its ends to the free end of the rod 70 by a hinge pin 72. The connecting rod 71 is articulated at its other end the fork 62 by a axis 73 of articulation distant from the axis 63 of pivoting of this fork 62.

Afin d'éviter les ponts thermiques entre le châssis 12 et l'élément 11 formant contenant du tiroir 2, chaque goujon 64 transversal du tiroir 2 coopérant avec une fourchette 62, est associé rigidement à l'extrémité libre 74 formant chape d'un bras 75 associé rigidement à la paroi avant 9 du tiroir 2 et s'étendant perpendiculairement vers l'intérieur 15 à partir de cette paroi 9.In order to avoid thermal bridges between the chassis 12 and the element 11 forming the container of the drawer 2, each stud 64 transverse of the drawer 2 cooperating with a fork 62, is rigidly associated with the free end 74 forming a yoke of an arm 75 rigidly associated with the front wall 9 of the drawer 2 and extending perpendicularly inward 15 from this wall 9.

On prévoit deux fourchettes 62 situées symétriquement de part et d'autre du tiroir 2, et coopérant respectivement avec deux goujons 64 portés par deux bras 75 solidaires de la paroi 9 du tiroir 2. L'arbre 65 du dispositif 61 de transmission commande alors respectivement en synchronisme deux biellette 70 et deux bielles 71 de connexion qui agissent elles-mêmes respectivement et en synchronisme sur les deux fourchettes 62 pour les entraîner en rotation autour de leur arbre de pivotement 63 (figure 6).There are two forks 62 located symmetrically on either side of the drawer 2, and cooperating respectively with two studs 64 carried by two arms 75 integral with the wall 9 of the drawer 2. The shaft 65 of the transmission device 61 then controls respectively in synchronism two connecting rods 70 and two connecting rods 71 which act themselves respectively and in synchronism with the two forks 62 to drive them in rotation around their pivot shaft 63 (FIG. 6).

Les deux bras 75 sont associés rigidement à la paroi avant 9 du tiroir 2 au voisinage de ses chants latéraux 20 de façon à coopérer respectivement avec les fourchettes 62 à travers deux orifices 76 ménagés dans la feuillure 21 du châssis 12. Le bras 75 gauche situé à proximité du boîtier 40 électrique coopère, lorsqu'il est engagé dans l'orifice 76 en position fermée/déverrouillée du tiroir 2, avec une languette 77 montée sur le châssis 12 et qui coopère elle-même avec le contacteur de position 35.The two arms 75 are rigidly associated with the front wall 9 of the drawer 2 in the vicinity of its lateral edges 20 so as to cooperate respectively with the forks 62 through two orifices 76 formed in the rebate 21 of the chassis 12. The left arm 75 located near the electrical box 40 cooperates, when it is engaged in the orifice 76 in the closed / unlocked position of the drawer 2, with a tongue 77 mounted on the chassis 12 and which itself cooperates with the position switch 35.

Le fonctionnement du dispositif de transmission 61 et de la fourchette 62 apparaît clairement sur les figures 7a et 7b. Lorsque le tiroir 2 est en position fermée/déverrouillée (figure 7a), la languette 77 actionne le contacteur de position 35, et, lorsque le temps de temporisation To est écoulé, le moteur électrique 28 entraîne l'arbre de sortie 37 en rotation dans le sens du verrouillage, qui lui-même commande la rotation de l'arbre de transmission 65, de la biellette 70, de la biellette 71, et donc de la fourchette 62 autour de son axe 63. Dès lors, le goujon 64 qui est en regard de la fourchette 62 lorsque le tiroir 2 est en position fermée/déverrouillée, est engagé dans la fourchette 62 lors de sa rotation, et le tiroir 2 est ainsi placé en position fermée/verrouillée (figure 7b).The operation of the transmission device 61 and the fork 62 is clearly shown in Figures 7a and 7b. When the drawer 2 is in the closed / unlocked position (FIG. 7a), the tongue 77 actuates the position switch 35, and, when the delay time To has elapsed, the electric motor 28 drives the output shaft 37 in rotation in the direction of locking, which itself controls the rotation of the transmission shaft 65, of the link 70, of the link 71, and therefore of the fork 62 around its axis 63. Consequently, the stud 64 which is opposite the fork 62 when the drawer 2 is in the closed / unlocked position, is engaged in the fork 62 during its rotation, and the drawer 2 is thus placed in the closed / locked position (FIG. 7b).

En position ouverte, même si le moteur 28 entraîne accidentellement la fourchette 62, celle-ci n'a aucun effet sur le tiroir 2 puisque le goujon 64 est éloigné de cette fourchette 62. Ainsi, selon l'invention, les moyens 16 de verrouillage/déverrouillage sont complètement dissociés du tiroir 2 et ne peuvent avoir aucun effet sur ce tiroir 2 même de façon accidentelle lorsque ce tiroir 2 est en position ouverte.In the open position, even if the motor 28 accidentally drives the fork 62, the latter has no effect on the drawer 2 since the stud 64 is distant from this fork 62. Thus, according to the invention, the locking means 16 / unlocking are completely dissociated from drawer 2 and can have no effect on this drawer 2 even accidentally when this drawer 2 is in the open position.

Dans un mode de réalisation particuliérement avantageux mais non représenté, les axes de pivotement 63 de la fourchette 62 et d'articulation 73 de la bielle 71 sur la fourchette 62 peuvent être placés de fa on que ce goujon 64 soit sensiblement aligné horizontalement avec l'axe de pivotement 63 de la fourchette 62, mais à l'opposé de la paroi 9 du tiroir 2, en position fermée/verrouillée. Une telle disposition assure un verrouillage mécanique du tiroir 2. Elle nécessite cependant une légère fléxibilité ou une articulation du bras 75 pour que le goujon 64 puisse passer sous l'axe de pivotement 63 de la fourchette 62.In a particularly advantageous embodiment but not shown, the pivot axes 63 of the fork 62 and articulation 73 of the connecting rod 71 on the fork 62 can be placed so that this stud 64 is substantially aligned horizontally with the pivot axis 63 of the fork 62, but opposite the wall 9 of the drawer 2, in the closed / locked position. Such an arrangement ensures mechanical locking of the drawer 2. However, it requires a slight flexibility or an articulation of the arm 75 so that the stud 64 can pass under the pivot axis 63 of the fork 62.

Lorsque le tiroir 2 est en position fermée/verrouillée, c'est-à-dire dans sa position normale de sécurité, l'utilisateur pour ouvrir le tiroir 2 doit insérer la clé dans les moyens interrupteur à serrure 43, puis appuyer sur le bouton poussoir 17. Si le dispositif fonctionne, le tiroir 2 est alors placé en position fermée/déverrouillée grâce à la rotation de la fourchette 62, et le tiroir 2 peut être facilement ouvert à partir de cette position par simple traction sur la poignée 10. Au cas où le dispositif ne fonctionnerait pas en réponse à l'actionnement du bouton poussoir 17, les accumulateur 29 sont déchargés, ou un des éléments du mobilier 1 est défaillant. Dans un tel cas, l'utilisateur branchera le boîtier électrique 40 au secteur par l'intermédiaire de la prise 31. Si le voyant 42 s'allume, le dispositif chargeur/redresseur 30 est alors en fonctionnement, et une nouvelle action sur le bouton poussoir 17 doit faire fonctionner les moyens 16 motorisés de verrouillage/déverrouillage. Dans le cas contraire, une intervention s'impose sur le boîtier électrique 40. Pour ce faire, il suffit de débrancher le secteur, d'insérer la clé dans le dispositif 47 à serrure pour libérer le boitier 40, et de tirer ce boîtier 40 vers l'avant afin d'examiner ses différents constituants.When the drawer 2 is in the closed / locked position, that is to say in its normal safety position, the user to open the drawer 2 must insert the key into the lock switch means 43, then press the button. pusher 17. If the device works, the drawer 2 is then placed in the closed / unlocked position by virtue of the rotation of the fork 62, and the drawer 2 can be easily opened from this position by simply pulling on the handle 10. Au if the device does not operate in response to actuation of the push button 17, the accumulators 29 are discharged, or one of the elements of the furniture 1 is faulty. In such a case, the user will connect the electrical box 40 to the mains via of the socket 31. If the light 42 lights up, the charger / rectifier device 30 is then in operation, and a new action on the push button 17 must operate the motorized means 16 for locking / unlocking. Otherwise, intervention is required on the electrical box 40. To do this, simply disconnect the power, insert the key into the device 47 with lock to release the box 40, and pull this box 40 forward to examine its various constituents.

L'arbre de sortie 37 des moyens 16 de verrouillage/déverrouillage coopère avec l'arbre 65 d'entrée du dispositif 61 de transmission de sorte que le boîtier 40 électrique ne peut être extrait hors du châssis 12 que lorsque le tiroir 2 est en position fermée/verrouillée. Mais en cas de panne, en position normale, le tiroir 2 est nécessairement en position fermée/verrouillée et c'est pourquoi le boîtier 40 peut être facilement extrait. Après extraction, le tiroir 2 peut éventuellement être manoeuvré manuellement à partir de la position fermée/verrouillée.The output shaft 37 of the locking / unlocking means 16 cooperates with the input shaft 65 of the transmission device 61 so that the electrical box 40 can only be extracted from the chassis 12 when the drawer 2 is in position closed / locked. But in the event of a breakdown, in the normal position, the drawer 2 is necessarily in the closed / locked position and this is why the housing 40 can be easily removed. After extraction, the drawer 2 can optionally be operated manually from the closed / locked position.

La poignée 10 est de préférence conformée de façon à offrir une prise relativement faible pour éviter que l'utilisateur ne puisse forcer sur cette poignée et sur le tiroir 2 dans le sens de l'ouverture si l'un des éléments mécaniques du dispositif 61 de transmission venait à se bloquer notamment en position fermée/déverrouillée.The handle 10 is preferably shaped so as to offer a relatively weak grip to prevent the user from being able to force on this handle and on the drawer 2 in the opening direction if one of the mechanical elements of the device 61 transmission was especially blocked in the closed / unlocked position.

L'invention peut faire l'objet de multiples variantes et applications évidentes à l'homme du métier non limitées au mode de réalisation préférentiel représenté sur les figures et décrit ci-dessus, donné uniquement à titre d'exemple. Par exemple les moyens 16 motorisés de verrouillage/déverrouillage et les moyens 17 de commande peuvent être hydrauliques ou pneumatiques au lieu d'être électriques, ainsi que les parties qui leurs sont communes.The invention can be the subject of multiple variants and applications obvious to those skilled in the art not limited to the preferred embodiment shown in the figures and described above, given only by way of example. For example, the motorized locking / unlocking means 16 and the control means 17 can be hydraulic or pneumatic instead of being electric, as are the parts which are common to them.
