Definitions

  • the invention relates to a device for closing an access opening, comprising an opening generally consisting of a flat rectangular plate, a frame which comprises at least one rectangular frame delimiting said access opening, and means for mobile association of each opening with the frame making it possible to move the opening with respect to the frame from a closed position in which it closes at least partially the access opening, to an open position in which it leaves the opening free to allow access through this opening, and vice versa.

Description

L'invention concerne un dispositif de fermeture d'une ouverture d'accès, comprenant un ouvrant globalement constitué d'une plaque plane rectangulaire, un dormant qui comporte au moins un encadrement rectangulaire délimitant la dite ouverture d'accès, et des moyens d'association mobile de chaque ouvrant au dormant permettant de déplacer l'ouvrant par rapport à l'encadrement d'une position de fermeture dans laquelle il vient fermer au moins en partie l'ouverture d'accès, à une position d'ouverture dans laquelle il laisse libre l'ouverture pour permettre l'accès à travers cette ouverture, et vice-versa.The invention relates to a device for closing an access opening, comprising an opening generally consisting of a flat rectangular plate, a frame which comprises at least one rectangular frame delimiting said access opening, and means for mobile association of each opening with the frame making it possible to move the opening with respect to the frame from a closed position in which it closes at least partially the access opening, to an open position in which it leaves the opening free to allow access through this opening, and vice versa.

De très nombreux types de tels dispositifs de fermeture sont connus, qu'il s'agisse de portes, fenêtres ou autres, et utilisés dans de nombreuses applications, notamment l'immobilier et les éléments d'aménagement.Many types of such closure devices are known, whether doors, windows or other, and used in many applications, including real estate and furnishings.

Dans les dispositifs les plus classiques, chaque ouvrant forme battant et est articulé à pivotement autour d'un axe solidaire du dormant matérialisé par des charnières, gonds ou autres. Dans d'autres types de dispositifs, chaque ouvrant est associé au dormant à pivotement autour de plusieurs axes de pivotement, ou autour d'un axe de pivotement mobile et non matérialisé (c'est-à-dire un axe de rotation théorique instantané dont la position peut varier dans le temps). Tel est le cas par exemple dans la demande de brevet français non publiée N° 8606054. D'autres types de dispositifs sont connus dans lequels l'ouvrant se déplace par translation ou translation/rotation. Dans tous les cas, les moyens d'association mobile connus ont essentiellement deux fonctions distinctes et antagonistes: d'une part porter l'ouvrant en l'associant au dormant de façon généralement ferme et sans jeu, et d'autre part permettre le déplacement entre les deux positions d'ouverture et de fermeture.In the most conventional devices, each opening leaf shape and is pivotally articulated about an axis integral with the frame materialized by hinges, hinges or the like. In other types of devices, each opening is associated with the frame pivoting around several pivot axes, or around a mobile and non-materialized pivot axis (that is to say an instantaneous theoretical axis of rotation whose position may vary over time). This is the case for example in the unpublished French patent application No. 8606054. Other types of devices are known in which the opening moves by translation or translation / rotation. In all cases, the known mobile association means essentially have two distinct and antagonistic functions: on the one hand carrying the door by associating it with the frame in a generally firm and play-free manner, and on the other hand allowing movement between the two open and closed positions.

On sait qu'en position de fermeture, la position de l'ouvrant par rapport au dormant, et notamment le centrage de l'ouvrant par rapport à l'encadrement, doivent être réalisés avec beaucoup de précision, et ce pour diverses raisons (bonne herméticité, bon fonctionnement des serrures, esthétique...). Cela oblige en pratique à employer des moyens d'association de l'ouvrant au dormant excessivement solides et sophistiqués, et montés avec une grande précision, dans les applications pour lesquelles le dormant et/ou l'encadrement peuvent être ou devenir légèrement gauches, déformables ou non parfaitement à l'équerre, ou encore lorsque l'ouvrant est particulièrement lourd.It is known that in the closed position, the position of the opening relative to the frame, and in particular the centering of the opening relative to the frame, must be carried out with great precision, and this for various reasons (good hermeticity, proper functioning of the locks, aesthetics ...). In practice, this requires the use of excessively solid and sophisticated means of opening the sash with the frame, and mounted with great precision, in applications for which the frame and / or the frame may be or become slightly awkward, deformable. or not perfectly square, or even when the opening is particularly heavy.

Le problème se pose en particulier avec acuité pour les éléments d'aménagement tels que les meubles de bureaux ou d'ateliers devant contenir des objets relativement lourds, par exemple des dossiers ou des outils. En effet, pour de tels meubles, généralement métalliques, les tolérances de fabrication sont relativement grossières et le centrage de l'ouvrant par rapport à l'encadrement est réalisé à vide. Or, une fois le meuble installé et rempli, on constate souvent des défauts à la fermeture dus à la déformation de l'encadrement et/ou du dormant qui ont nécessairement une certaine souplesse, déformation engendrée par la charge et/ou mauvais calage du meuble par rapport au sol. De plus, les charnières ou gonds généralement utilisés tendent à fléchir sous le poids de l'ouvrant. Classiquement, il est quasiment impossible d'obtenir deux ouvrants articulés sur le même encadrement parfaitement centrés, de niveau, et le rester. Par exemple, un mauvais calage engendre une légère déformation de l'encadrement dans son plan, et un décentrage de l'ouvrant par rapport à l'encadrement.The problem is particularly acute for furnishing elements such as office or workshop furniture which must contain relatively heavy objects, for example files or tools. Indeed, for such furniture, generally metallic, the manufacturing tolerances are relatively coarse and the centering of the opening relative to the frame is carried out empty. However, once the furniture is installed and filled, there are often defects in closing due to the deformation of the frame and / or the frame which necessarily have a certain flexibility, deformation caused by the load and / or poor setting of the furniture. relative to the ground. In addition, the hinges or hinges generally used tend to bend under the weight of the door. Conventionally, it is almost impossible to obtain two openings articulated on the same frame perfectly centered, level, and remain so. For example, a bad setting generates a slight deformation of the frame in its plane, and a decentering of the opening relative to the frame.

Une première solution à ce problème consiste à monter le meuble sur des vérins verticaux permettant de rectifier si nécessaire l'assiette du meuble en fonction du relief du sol, et éviter tout défaut de calage. Cette solution extrêmement sophistiquée est onéreuse. De plus, le réglage initial des vérins doit être corrigé régulièrement. Enfin, les vérins ne permettent pas de remédier à la légère déformation des charnières ou gonds sous l'effet du poids de l'ouvrant.A first solution to this problem consists in mounting the piece of furniture on vertical jacks making it possible to correct if necessary the trim of the piece of furniture as a function of the relief of the ground, and to avoid any defect in setting. This extremely sophisticated solution is expensive. In addition, the initial setting of the cylinders must be corrected regularly. Finally, the jacks do not make it possible to remedy the slight deformation of the hinges or hinges under the effect of the weight of the opening.

Une deuxième solution consiste à prévoir des moyens d'ajustement du centrage de l'ouvrant sur les charnières d'articulation de cet ouvrant permettant de régler à volonté la position de cet ouvrant par rapport à l'encadrement en position de fermeture. (Brevets français 2456201, 2355149, 221612, 2221611, 2372949, 2222520, 2111044, 2111464). Une telle solution n'est cependant applicable qu'aux charnières classiques utilisables en menuiserie, et surtout nécessite des réglages réguliers au fur et à mesure du fluage des charnières ou du dormant. De plus les charnières ainsi équipées sont complexes, onéreuses et ne permettent pas de supporter des ouvrants de poids élevé.A second solution consists in providing means for adjusting the centering of the opening on the hinges of articulation of this opening making it possible to adjust at will the position of this opening relative to the frame in the closed position. (French patents 2456201, 2355149, 221612, 2221611, 2372949, 2222520, 2111044, 2111464). However, such a solution is only applicable to conventional hinges usable in carpentry, and above all requires regular adjustments as the creep of the hinges or the frame. In addition, the hinges thus equipped are complex, costly and do not allow to support large openings.

Par ailleurs, dans d'autres applications telles que l'immobilier, on constate souvent, malgré l'utilisation de gonds surdimensionnés, des défauts de fermeture dus à des déformations des gonds et/ou de l'encadrement et/ou de l'ouvrant au cours de l'utilisation. Ces déformations sont généralement inévitables du fait que, pour remplir correctement simultanément les deux fonctions antagonistes précitées, les gonds devraient être exagérément renforcés, ce qui nuit en général à l'esthétique et surtout au prix de revient.Furthermore, in other applications such as real estate, we often find, despite the use of oversized hinges, closing defects due to deformations of the hinges and / or the frame and / or the opening during use. These deformations are generally inevitable since, to correctly fulfill the two abovementioned antagonistic functions simultaneously, the hinges should be excessively reinforced, which generally harms the aesthetics and especially the cost price.

Une troisième solution consiste à prévoir des organes de soutien du battant montés d'une part sur le chant vertical libre du battant, et d'autre part sur l'huisserie à un niveau correspondant. Les brevets américain US-2453049 et allemands DE-1584005 et DE-1298907 décrivent déjà divers modes de réalisation possibles de tels organes qui fonctionnent comme des cames. Cependant, là encore, il est nécessaire de régler régulièrement la position relative de ces organes en fonction du fluage ou de l'usure des charnières. Par ailleurs, avec de tels organes, l'ajustement réalisé ne peut être que de très faible amplitude, car il va à l'encontre de la position normale imposée par les charnières. Il s'agit dans tous les cas de comparer une usure, et non de permettre véritablement un ajustement automatique du centrage des battants.A third solution consists in providing support elements for the leaf mounted on the one hand on the free vertical edge of the leaf, and on the other hand on the frame at a corresponding level. American patents US-2453049 and German DE-1584005 and DE-1298907 already describe various possible embodiments of such members which function like cams. However, here again, it is necessary to regularly adjust the relative position of these members as a function of creep or wear of the hinges. Furthermore, with such members, the adjustment carried out can only be of very small amplitude, because it goes against the normal position imposed by the hinges. In all cases, it is a question of comparing wear, and not really allowing automatic adjustment of the centering of the leaves.

L'invention vise donc à remédier aux inconvénients précités de l'état de la technique en fournissant un dispositif de fermeture dans lequel l'ouvrant est automatiquement, et correctement centré par rapport à l'encadrement, (notamment lors de chaque manoeuvre), de sorte que la fermeture soit toujours correctement réalisée, sans coincement, et ce même après un usage prolongé dans des conditions difficiles (telles que celles résultant d'une utilisation dans un atelier ou dans l'industrie). L'invention vise aussi à proposer un tel dispositif dans lequel l'axe de pivotement, et plus généralement les moyens de guidage, de l'ouvrant ne participent pas à et ne gênent pas cet ajustement du centrage de l'ouvrant. L'invention vise également à fournir un tel dispositif dont le prix de revient est extrêmement faible, notamment inférieur ou faiblement supérieur à celui des dispositifs connus. L'invention vise également à permettre le perfectionnement des dispositifs déjà installés et en usage. L'invention vise aussi à assurer automatiquement, en position de fermeture, l'alignement de deux ouvrants associés à une même ouverture et ayant des chants en regard en partie médiane de cette ouverture, de façon à assurer une bonne fermeture et un aspect esthétique extérieur optimal.The invention therefore aims to remedy the aforementioned drawbacks of the state of the art by providing a closing device in which the opening is automatically, and correctly centered with respect to the frame, (in particular during each maneuver), so that the closure is always carried out correctly, without jamming, even after prolonged use under difficult conditions (such as those resulting from use in a workshop or in industry). The invention also aims to propose such a device in which the pivot axis, and more generally the guide means, of the opening do not participate in and do not interfere with this adjustment of the centering of the opening. The invention also aims to provide such a device whose cost price is extremely low, in particular lower or slightly higher than that of known devices. The invention also aims to allow the improvement of the devices already installed and in use. The invention also aims to automatically ensure, in the closed position, the alignment of two opening elements associated with the same opening and having facing edges in the middle part of this opening, so as to ensure good closing and an external aesthetic appearance. optimal.

L'invention a par ailleurs pour objet un élément d'aménagement notamment un meuble d'atelier tel qu'un armoire de stockage d'outils ou autres objets lourds, dont les manoeuvres de fermeture sont constamment faciles et sûres, et ce même après une longue utilisation dans des conditions difficiles (surcharge, mauvais calage, chocs...) et sans nécessiter des interventions de réglage régulières. Un autre objet de l'invention est d'augmenter la rigidité de l'élément d'aménagement en position de fermeture de ses ouvrants.The subject of the invention is moreover a design element, in particular a workshop furniture such as a tool storage cabinet or other heavy objects, the closing operations of which are constantly easy and safe, even after a long use in difficult conditions (overload, poor timing, shocks ...) and without requiring regular adjustment interventions. Another object of the invention is to increase the rigidity of the fitting element in the closed position of its opening elements.

Pour ce faire, l'invention propose un dispositif de fermeture d'une ouverture d'accès ― notamment d'un élément d'aménagement tel qu'un meuble d'atelier ― comprenant au moins un ouvrant globalement constitué d'une plaque plane rectangulaire, un dormant qui comporte au moins un encadrement rectangulaire délimitant ladite ouverture d'accès, et des moyens d'association mobile de chaque ouvrant au dormant, permettant de déplacer l'ouvrant par rapport à l'encadrement d'une position de fermeture dans laquelle il vient fermer au moins en partie l'ouverture d'accès à une position d'ouverture dans laquelle il laisse libre l'ouverture pour permettre l'accès à travers cette ouverture, et vice-versa, et comportant des moyens d'ajustement du centrage de l'ouvrant par rapport à l'encadrement qui sont distincts, indépendants et éloignés des moyens d'association mobile de l'ouvrant au dormant, caractérisé en ce que les moyens d'association mobile de l'ouvrant au dormant laissent l'ouvrant, au moins en position de fermeture, libre de branler par rapport à l'encadrement avec un jeu au moins dans les directions parallèles au plan P1 de l'encadrement ou P3 de l'ouvrant ― notamment un jeu de l'ordre de la distance normale qui sépare l'encadrement de chaque chant de l'ouvrant ―, de sorte que les moyens d'association mobile de l'ouvrant au dormant ne participent pas à et ne gênent pas l'ajustement du centrage de l'ouvrant par rapport à l'encadrement, les moyens d'ajustement réalisant le centrage de et maintenant centré l'ouvrant en position de fermeture.To do this, the invention provides a device for closing an access opening - in particular a fitting element such as a workshop piece of furniture - comprising at least one opening generally made up of a rectangular flat plate , a frame which comprises at least one rectangular frame delimiting said access opening, and means of mobile association of each opening with the standing, making it possible to move the opening with respect to the frame from a closed position in which it comes to close at least partially the access opening to an open position in which it leaves the opening free to allow access through this opening, and vice versa, and comprising means for adjusting the centering of the opening relative to the frame which are distinct, independent and distant from the means of mobile association of the opening with the frame, characterized in that the means of mobile association of the opening with the frame leave the opening, at least in the closed position, free to wank relative to the frame with a clearance at least in the directions parallel to the plane P1 of the framework or P3 of the opening - in particular a clearance of the order the normal distance which separates the framing of each edge of the sash -, so that the means of mobile association of the sash with the frame do not participate in and do not interfere with the adjustment of the centering of the opening relative to the frame, the adjustment means realizing the centering of and now centered the opening in the closed position.

Les moyens d'ajustement du centrage de l'ouvrant par rapport à l'encadrement sont actifs lorsque l'ouvrant est en position de fermeture et inactifs dans les autres positions de l'ouvrant, et sont actifs automatiquement lorsque l'ouvrant vient en position de fermeture, à chaque manoeuvre.The means for adjusting the centering of the opening relative to the frame are active when the opening is in the closed position and inactive in the other positions of the opening, and are automatically active when the opening comes into position. closing, at each maneuver.

De plus, selon l'invention, les moyens d'association mobile de l'ouvrant au dormant laissent l'ouvrant, au moins en position de fermeture, libre de branler par rapport à l'encadrement avec un jeu au moins dans les directions parallèles au plan P1 de l'encadrement ou P3 de l'ouvrant ― notamment un jeu de l'ordre de la distance normale qui sépare l'encadrement de chaque chant de l'ouvrant ―, de sorte que ces moyens d'association mobile de l'ouvrant au dormant ne participent pas à et ne gênent pas l'ajustement du centrage de l'ouvrant par rapport à l'encadrement lorsque cet ouvrant est en position de fermeture. L'invention concerne également un tel dispositif de fermeture comportant en combinaison avec les caractéristiques précédentes des moyens d'association mobile de l'ouvrant au dormant tels que décrit dans la demande de brevet français non publiée N° 8606054. L'invention concerne aussi un élément d'aménagement notamment un meuble d'atelier tel qu'une armoire de rangement d'outils ou autres objets lourds ― comportant un dispositif de fermeture selon l'invention.In addition, according to the invention, the means of mobile association of the sash with the frame leaves the sash, at least in the closed position, free to wiggle relative to the frame with play at least in the parallel directions. at the plane P1 of the frame or P3 of the opening - in particular a play of the order of the normal distance which separates the frame from each edge of the opening -, so that these means of mobile association of the opening to the frame do not participate in and do not interfere with the adjustment of the centering of the opening relative to the frame when this opening is in the closed position. The invention also relates to such a closure device comprising, in combination with the preceding characteristics, means of mobile association of the leaf to the frame as described in the unpublished French patent application No. 8606054. The invention also relates to a design element including a workshop furniture such as a tool storage cabinet or other heavy objects - comprising a closure device according to the invention.

D'autres caractéristiques et avantages de l'invention apparaîtront à la lumière de la description suivante, se référant à la figure unique annexée représentant schématiquement en perspective le mode de réalisation préférentiel d'un élément d'aménagement selon l'invention muni d'un dispositif de fermeture selon l'invention.Other characteristics and advantages of the invention will appear in the light of the following description, with reference to the single appended figure schematically showing in perspective the preferred embodiment of an arrangement element according to the invention provided with a closing device according to the invention.

Dans le contexte de la présente demande de brevet, le terme "dispositif de fermeture" désigne un dispositif permettant à volonté d'obturer ou de dégager une ouverture d'accès 1 séparant un premier espace 2 dénommé "espace intérieur" par convention, bien qu'il ne soit pas nécessairement clos ni situé à l'intérieur de quelque chose dans l'absolu, d'un second espace 3 dénommé "espace extérieur" par opposition au premier. Bien entendu, dans l'application préférentielle particulière de l'invention à un élément d'aménagement 4, l'ouverture d'accès 1 considérée est celle qui sépare l'expace intérieur 2 de l'élément d'aménagement 4 de l'espace extérieur 3 en permettant l'accès à l'intérieur 2 de l'élément d'aménagement 4, ce qui justifie la dénomination conventionnelle précitée pour ces espaces 2, 3.In the context of the present patent application, the term "closing device" designates a device allowing at will to close or clear an access opening 1 separating a first space 2 called "interior space" by convention, although '' it is not necessarily enclosed or located inside something in the absolute, a second space 3 called "outdoor space" as opposed to the first. Of course, in the particular preferential application of the invention to a fitting element 4, the access opening 1 considered is that which separates the interior space 2 from the fitting element 4 from the space exterior 3 by allowing access to the interior 2 of the furnishing element 4, which justifies the aforementioned conventional designation for these spaces 2, 3.

Un dispositif de fermeture d'une ouverture d'accès 1 comprend au moins un ouvrant 5 globalement constitué d'une plaque plane rectangulaire dont les dimensions correspondent à au moins une partie de celles de l'ouverture d'accès 1, un dormant qui comporte au moins un encadrement rectangulaire 6 délimitant la dite ouverture d'accès 1, et des moyens 7 d'association mobile de chaque ouvrant 5 au dormant permettant de déplacer cet ouvrant 5 par rapport à l'encadrement 6 d'une position de fermeture dans laquelle il vient fermer au moins en partie l'ouverture d'accès 1, à une position d'ouverture dans laquelle il laisse libre l'ouverture 1 pour permettre l'accès à travers cette ouverture 1 de l'espace extérieur 3 dans l'espace intérieur 2, et vice-versa de la position d'ouverture à la position de fermeture.A device for closing an access opening 1 comprises at least one opening 5 generally made up of a flat rectangular plate whose dimensions correspond to at least part of those of the access opening 1, a frame which comprises at least one rectangular frame 6 delimiting said access opening 1, and means 7 for mobile association of each opening 5 with the frame making it possible to move this opening 5 relative to the frame 6 from a closed position in which it comes at least partially to close the access opening 1, to an open position in which it leaves the opening 1 free to allow access through this opening 1 from the external space 3 into the space interior 2, and vice versa from the open position to the closed position.

L'ouvrant 5 rectangulaire doit, en position de fermeture, être correctement placé par rapport à l'encadrement 6. En particulier, il doit être dans le plan P1 de l'encadrement 6 lorsque chaque ouvrant 5 vient en position de fermeture à l'intérieur de l'encadrement 6, comme représenté, ou au moins dans un plan parallèle à P1. De plus, et surtout, les chants 8, 9, 10, 11 de l'ouvrant 5 doivent être strictement parallèles et en regard des montants et traverses 6a, 6b, 6c, 6d formant l'encadrement 6, c'est-à-dire que l'ouvrant 5 doit être bien "centré" par rapport à l'encadrement 6. Dans toute la suite, le terme "centrer" et ses dérivés seront utilisés dans le sens précité. Dans le mode de réalisation représenté, l'ouvrant 5 en position de fermeture est centré par rapport à l'encadrement 6, et n'a pas subi de rotation autour d'un axe perpendiculaire à son plan P3 par rapport à l'encadrement 6.The rectangular opening 5 must, in the closed position, be correctly positioned relative to the frame 6. In particular, it must be in the plane P1 of the frame 6 when each opening 5 comes in the closed position at inside the frame 6, as shown, or at least in a plane parallel to P1. In addition, and above all, the edges 8, 9, 10, 11 of the opening 5 must be strictly parallel and opposite the uprights and crosspieces 6a, 6b, 6c, 6d forming the frame 6, that is to say say that the opening 5 must be well "centered" relative to the frame 6. In the following, the term "center" and its derivatives will be used in the above sense. In the embodiment shown, the opening 5 in the closed position is centered relative to the frame 6, and has not been rotated about an axis perpendicular to its plane P3 relative to the frame 6 .

Un dispositif de fermeture selon l'invention comporte des moyens 12 d'ajustement du centrage de l'ouvrant 5 par rapport à l'encadrement 6 qui sont distincts, indépendants et éloignés des moyens 7 d'association mobile de l'ouvrant 5 au dormant et permettent ainsi d'assurer le meilleur centrage possible de l'ouvrant 5 par rapport à l'encadrement 6, même lorsque le dormant, l'encadrement 6, ou les moyens 7 d'association mobile de l'ouvrant 5 au dormant sont légèrement gauches, déformés ou non parfaitement à l'équerre. De plus, selon l'invention, les moyens 12 d'ajustement du centrage de l'ouvrant 5 par rapport à l'encadrement 6 sont actifs automatiquement lorsque l'ouvrant 5 vient en position de fermeture, c'est-à-dire sans nécessité d'une manoeuvre spécifique supplémentaire de l'utilisateur, et ajustent automatiquement le centrage de l'ouvrant 5 à chaque manoeuvre de cet ouvrant 5 en position de fermeture. Les moyens 12 d'ajustement du centrage de l'ouvrant 5 par rapport à l'encadrement 6 sont actifs lorsque l'ouvrant 5 est en position de fermeture, et inactifs dans les autres positions de l'ouvrant 5.A closure device according to the invention comprises means 12 for adjusting the centering of the opening 5 relative to the frame 6 which are distinct, independent and distant from the means 7 mobile association of the opening 5 to the frame and thus ensure the best possible centering of the opening 5 relative to the frame 6, even when the frame, the frame 6, or the means 7 of mobile association of the opening 5 to the frame are slightly awkward, deformed or not perfectly square. In addition, according to the invention, the means 12 for adjusting the centering of the opening 5 relative to the frame 6 are active automatically when the opening 5 comes into the closed position, that is to say without need for an additional specific operation of the user, and automatically adjust the centering of the opening 5 each time this opening 5 is operated in the closed position. The means 12 for adjusting the centering of the opening 5 relative to the frame 6 are active when the opening 5 is in the closed position, and inactive in the other positions of the opening 5.

Selon l'invention, les moyens 7 d'association mobile de l'ouvrant 5 au dormant laissent l'ouvrant 5, au moins en position de fermeture, libre de branler par rapport à l'encadrement 6 avec un jeu au moins les directions parallèles au plan P1 de l'encadrement 6 ou dans les directions parallèles au plan P3 de l'ouvrant 5 ― notamment un jeu de l'ordre de la distance normale qui sépare l'encadrement 6 de chaque chant 8, 9, 10, 11 de l'ouvrant 5 ―, de sorte que ces moyens 7 d'association mobile de l'ouvrant 5 au dormant ne participent pas à et ne gênent pas l'ajustement du centrage de l'ouvrant 5 par rapport à l'encadrement 6 lorsque cet ouvrant 5 est en position de fermeture, les moyens 12 d'ajustement réalisant le centrage de et maintenant rigidement centré l'ouvrant 5 en position de fermeture, dans une position autorisée par le jeu laissé par les moyens 7 d'association mobile.According to the invention, the means 7 for movable association of the opening 5 with the frame leaves the opening 5, at least in the closed position, free to wiggle relative to the frame 6 with play at least in the parallel directions in the plane P1 of the frame 6 or in the directions parallel to the plane P3 of the opening 5 - in particular a clearance of the order of the normal distance which separates the frame 6 from each edge 8, 9, 10, 11 of the opening 5 -, so that these means 7 of mobile association of the opening 5 with the frame do not participate in and do not interfere with the adjustment of the centering of the opening 5 relative to the frame 6 when this opening 5 is in the closed position, the adjustment means 12 centering and now rigidly centered the opening 5 in the closed position, in a position authorized by the clearance left by the means 7 of mobile association.

Les moyens 7 d'association mobile maintiennent fermement sans jeu l'ouvrant 5 en position de fermeture dans la direction perpendiculaire à son plan P3 ou à celui P1 de l'encadrement 6. Au contraire, dans les directions parallèles au plan P3 de l'ouvrant 5 ou à celui P1 de l'encadrement 6, les moyens 12 d'ajustement, seuls, maintiennent et supportent l'ouvrant 5 fermement et sans jeu. Le jeu de l'ouvrant 5 laissé par les moyens d'association mobile a lieu dans les directions parallèles au plan P1 de l'encadrement 6, et ce quelque soit la position de l'ouvrant 5 par rapport au dormant.The movable association means 7 firmly maintain the opening 5 in the closed position without play in the direction perpendicular to its plane P3 or to that of the frame P1 6. On the contrary, in the directions parallel to the plane P3 of the opening 5 or to that P1 of the frame 6, the adjustment means 12, alone, hold and support the opening 5 firmly and without play. The play of the opening 5 left by the mobile association means takes place in the directions parallel to the plane P1 of the frame 6, regardless of the position of the opening 5 relative to the frame.

De la sorte, les moyens 7 d'association mobile de l'ouvrant 5 réalisent uniquement la fonction de guidage de l'ouvrant 5 lorsqu'il est en position de fermeture. La fonction de support de cet ouvrant 5 en position de fermeture est donc séparée des moyens 7 d'association mobile, et est remplie intégralement et uniquement par les moyens 12 d'ajustement du centrage de l'ouvrant 5 par rapport à l'encadrement 6.In this way, the means 7 for movable association of the opening 5 only perform the function of guiding the opening 5 when it is in the closed position. The support function of this opening 5 in the closed position is therefore separate from the means 7 of mobile association, and is fulfilled entirely and only by the means 12 for adjusting the centering of the opening 5 relative to the frame 6 .

De plus, les moyens 7 d'association mobile de l'ouvrant 5 au dormant sont des moyens permettant un pivotement de l'ouvrant 5 par rapport à au moins un axe matérialisé ou théorique, fixe ou mobile, de pivotement parallèle à un côté 6a, 6b dans l'encadrement 6. Ces moyens 7 d'association mobile laissent l'ouvrant 5 libre de branler par rapport à l'encadrement 6 au moins dans la direction parallèle au plan P3 de cet ouvrant 5 ou au plan P1 de l'encadrement 6, et au moins perpendiculairement à l'axe de pivotement.In addition, the means 7 for mobile association of the door 5 with the frame are means allowing the door 5 to pivot relative to at least one material or theoretical axis, fixed or mobile, for pivoting parallel to a side 6a. , 6b in the frame 6. These movable association means 7 leave the sash 5 free to wank relative to the frame 6 at least in the direction parallel to the plane P3 of this sash 5 or to the plane P1 of the frame 6, and at least perpendicular to the pivot axis.

L'axe de pivotement est matérialisé et fixe dans les modes de réalisation où les moyens 7 d'association mobile de l'ouvrant 5 au dormant sont constitués de charnières à gonds; ou théorique et mobile par exemple dans le mode de réalisation décrit par la demande de brevet français N° 8606054.The pivot axis is materialized and fixed in the embodiments where the means 7 for mobile association of the opening 5 with the frame are made up of hinges with hinges; or theoretical and mobile, for example in the embodiment described by French patent application No. 8606054.

Dans d'autres modes de réalisations possibles, les moyens 7 d'association mobile permettent un pivotement de l'ouvrant 5 par rapport à plusieurs axes d'articulation parallèles matérialisés, fixes ou mobiles.In other possible embodiments, the mobile association means 7 allow pivoting of the opening 5 with respect to several parallel articulated axes, fixed or mobile.

Dans le mode de réalisation préférentiel représenté, les moyens 7 d'association mobile de chaque ouvrant 5 ou dormant sont conformes aux caractéristiques de la demande de brevet français N° 8606054, et sont du type permettant un pivotement de l'ouvrant 5 autour d'un axe de pivotement mobile et non matérialisé mais qui reste toujours parallèle au montant 6a, 6b de l'encadrement 6 et proche d'un de ces montants 6a, 6b. De tels moyens 7 d'association mobile comportent en premier lieu au moins un bras 13 articulé d'une part à un point fixe 14 d'une traverse 6c, 6d de l'encadrement 6, et d'autre part à l'ouvrant 5 en un point 15 éloigné des chants 8, 9 parallèles à l'axe de pivotement de l'ouvrant 5, en second lieu des moyens 16 de guidage d'un 8 de ces chants astreignant ce chant 8 à se déplacer contre un plan P2 sensiblement perpendiculaire au plan P1 de l'encadrement 6 et contenant un montant périphérique 6a ou 6b de l'encadrement 6, et en troisième lieu des moyens 17 de manoeuvre de l'ouvrant 5.In the preferred embodiment shown, the means 7 for movable association of each opening 5 or dormant conform to the characteristics of French patent application No. 8606054, and are of the type allowing pivoting of the opening 5 around a movable pivot axis not materialized but which always remains parallel to the upright 6a, 6b of the frame 6 and close to one of these uprights 6a, 6b. Such means 7 of mobile association comprise in the first place at least one arm 13 articulated on the one hand at a fixed point 14 of a cross 6c, 6d of the frame 6, and on the other hand to the opening 5 at a point 15 distant from the edges 8, 9 parallel to the pivot axis of the opening 5, secondly means 16 for guiding an 8 of these edges compelling this edge 8 to move against a plane P2 substantially perpendicular to the plane P1 of the frame 6 and containing a peripheral upright 6a or 6b of the frame 6, and thirdly means 17 for operating the opening 5 .

Selon l'invention, l'articulation 14 d'un bras 13 à traverse 6c, 6d de l'encadrement 6, comporte une lumière 18 oblongue dans la direction parallèle à celle de cette traverse 6c, 6d, de sorte que l'extrémité 19 de ce bras 13 articulée sur l'encadrement 6 dans la lumière 18 peut jouer dans cette lumière 18 parallèlement à la traverse 6c, 6d. Les deux lumières 18c, 18d prévues respectivement pour les traverses supérieures et inférieures 6c, 6d sont similaires, oblongues dans la même direction et situées à la verticale l'une de l'autre.According to the invention, the articulation 14 of an arm 13 with cross member 6c, 6d of the frame 6, includes a slot 18 oblong in the direction parallel to that of this cross member 6c, 6d, so that the end 19 of this arm 13 articulated on the frame 6 in the slot 18 can play in this slot 18 parallel to the cross 6c, 6d. The two slots 18c, 18d provided respectively for the upper and lower crosspieces 6c, 6d are similar, oblong in the same direction and situated vertically from one another.

Selon l'invention, les moyens 12 d'ajustement du centrage de l'ouvrant 5 par rapport à l'encadrement 6 en position de fermeture, sont éloignés de l'axe de pivotement de cet ouvrant 5 par rapport au dormant, et coopèrent avec les chants 10, 11 de l'ouvrant 5 venant, en position de fermeture, en regard des côtés 6c, 6d de l'encadrement qui sont perpendiculaires à l'axe de pivotement.According to the invention, the means 12 for adjusting the centering of the opening 5 relative to the frame 6 in the closed position, are distant from the pivot axis of this opening 5 relative to the frame, and cooperate with the edges 10, 11 of the opening 5 coming, in the closed position, facing the sides 6c, 6d of the frame which are perpendicular to the pivot axis.

Chaque ouvrant 5 vient en position de fermeture, de préférence à l'intérieur de l'encadrement 6, c'est-à-dire que les chants 8, 9, 10, 11 de cet ouvrant 5 viennent en position de fermeture en regard des montants et traverses 6a, 6b, 6c, 6d de l'encadrement 6. Cependant, une telle caractéristique n'est pas strictement nécessaire, dans la mesure où il existe d'autres modes de réalisation pour lesquelles l'ouvrant 5 vient recouvrir l'ouverture 1 et l'encadrement 6, modes de réalisation pour lesquels l'invention est également applicable.Each opening 5 comes in the closed position, preferably inside the frame 6, that is to say that the edges 8, 9, 10, 11 of this opening 5 come in the closed position opposite the uprights and crosspieces 6a, 6b, 6c, 6d of the frame 6. However, such a characteristic is not strictly necessary, insofar as there are other embodiments for which the opening 5 comes to cover the opening 1 and frame 6, embodiments for which the invention is also applicable.

Dans le mode de réalisation préférentiel représenté, les moyens 12 d'ajustement du centrage de chaque ouvrant 5 par rapport à l'encadrement 6 sont constitués d'au moins une roulette 12 solidaire d'un côté 6c, 6d de l'encadrement 6 et susceptible de coopérer avec un chant 10, 11 de l'ouvrant 5 venant, en position de fermeture, contre -notamment en regard de- ce côté 6c, 6d. Une roulette 12 d'ajustement du centrage d'un ouvrant 5 par rapport à l'encadrement 6 est montée libre en rotation autour d'un axe 20 parallèle aux côtés 6c, 6d de l'encadrement 6 qui la porte. Une roulette 12 d'ajustement du centrage d'un ouvrant 5 par rapport à l'encadrement 6 est solidaire d'une traverse 6c, 6d de l'encadrement 6 perpendiculaire à l'axe de pivotement de l'ouvrant 5. De plus, une telle roulette 12 est éloignée du montant 6a, 6b de l'encadrement 6 parallèle et proche de l'axe de pivotement de cet ouvrant 5, de sorte que cette roulette 12 coopère avec la partie 21 du chant 10, 11 de l'ouvrant 5 qui est la plus proche du chant 9 perpendiculaire de l'ouvrant 5 qui est opposé auxdits montants 6a, 6b de l'encadrement 6 parallèle et proche de l'axe de pivotement, c'est-à-dire avec la partie 21 du chant 10, 11 la plus éloignée de l'axe de pivotement.In the preferred embodiment shown, the means 12 for adjusting the centering of each opening 5 with respect to the frame 6 consist of at least one caster 12 secured on one side 6c, 6d of the frame 6 and likely to cooperate with a edge 10, 11 of the opening 5 coming, in the closed position, especially against-facing this side 6c, 6d. A wheel 12 for adjusting the centering of an opening 5 with respect to the frame 6 is mounted free to rotate about an axis 20 parallel to the sides 6c, 6d of the frame 6 which carries it. A centering adjustment wheel 12 an opening 5 relative to the frame 6 is integral with a cross 6c, 6d of the frame 6 perpendicular to the pivot axis of the opening 5. In addition, such a wheel 12 is distant from the amount 6a, 6b of the frame 6 parallel and close to the pivot axis of this opening 5, so that this caster 12 cooperates with the part 21 of the edge 10, 11 of the opening 5 which is closest to the edge 9 perpendicular to the opening 5 which is opposite to said uprights 6a, 6b of the frame 6 parallel and close to the pivot axis, that is to say with the part 21 of the edge 10, 11 furthest from the pivot axis.

Le dispositif de fermeture selon l'invention comporte deux roulettes 12c, 12d d'ajustement par ouvrant 5, montées respectivement sur deux côtés 6c, 6d opposés de l'encadrement 6 de façon symétrique, c'est-à-dire à même distance des autres côtés 6a, 6b dans l'encadrement 6, et définissant entre elles une hauteur ou une largeur de l'ouvrant 5, compte tenu bien entendu des tolérances industrielle. De la sorte, l'ouvrant 5 est en position de fermeture, maintenu entre ces deux roulettes 12c, 12d. Ainsi, la position de l'ouvrant 5 par rapport à ces roulettes 12c, 12d est imposée en position de fermeture, et ce quelles que soient les légères déformations éventuelles de l'encadrement 6. Cela est rendu possible grâce au jeu laissé par les lumières oblongues 18c, 18d d'articulation de bras 13c, 13d. Il a été ainsi constaté que le fait de prévoir de telles roulettes 12 et de laisser un jeu dans les moyens 7 d'association mobile permet d'obtenir une fermeture parfaite de l'ouvrant 5 sur l'encadrement 6, et ce contrairement à ce que prévoit l'état de la technique dans lequel les moyens d'articulation de l'ouvrant sont au contraire parfaitement et extrêmement rigides, et même surdimensionnés pour maintenir fermement l'ouvrant.The closure device according to the invention comprises two rollers 12c, 12d for adjusting by opening 5, mounted respectively on two opposite sides 6c, 6d of the frame 6 symmetrically, that is to say at the same distance from the other sides 6a, 6b in the frame 6, and defining between them a height or a width of the opening 5, taking into account of course industrial tolerances. In this way, the opening 5 is in the closed position, held between these two rollers 12c, 12d. Thus, the position of the opening 5 relative to these rollers 12c, 12d is imposed in the closed position, regardless of any slight deformations of the frame 6. This is made possible thanks to the play left by the lights oblong 18c, 18d arm articulation 13c, 13d. It has thus been found that the fact of providing such rollers 12 and of leaving a clearance in the means 7 of mobile association makes it possible to obtain perfect closure of the opening 5 on the frame 6, and this in contrast to this that provides for the state of the art in which the means of articulation of the opening are on the contrary perfectly and extremely rigid, and even oversized to firmly hold the opening.

Dans le mode de réalisation préférentiel représenté, le dispositif selon l'invention comporte deux ouvrant 5′, 5˝, rectangulaires, similaires associés à pivotement autour d'axes de pivotement respectivement parallèles entre eux et au moins sensiblement parallèles aux montants 6a, 6b de l'encadrement 6, chaque ouvrant 5 couvrant en position de fermeture la moitié de l'ouverture d'accès 1, les ouvrants 5 ayant, en position de fermeture, deux chants libres 9′, 9˝ centraux parallèles aux axes de pivotement, en regard l'un de l'autre. Les moyens 12 d'ajustement du centrage des ouvrants 5 par rapport à l'encadrement 6 coopèrent avec les chants 10, 11 des ouvrants 5 qui sont perpendiculaires aux axes de pivotement, et plus précisément avec la partie 21 de ces chants 10, 11 des ouvrants 5 qui qui est la plus proche des chants 9′, 9˝ centraux des ouvrants 5′, 5˝ venant en regard l'un de l'autre. Les moyens 12 d'ajustement du centrage des ouvrants 5′, 5˝ par rapport à l'encadrement 6 sont solidaires des traverses 6c, 6d de l'encadrement 6, symétriquement disposés autour du centre 22c, 22d de chaque traverse 6c, 6d et proches de ce centre 22c, 22d. Les lumières oblongues 18 d'articulation sont aussi symétriquement disposées par rapport au centre 22c, 22d de chaque traverse 6c, 6d.In the preferred embodiment shown, the device according to the invention comprises two opening 5 ′, 5˝, rectangular, similar associated with pivoting around pivot axes respectively parallel to each other and at least substantially parallel to the uprights 6a, 6b of the frame 6, each opening 5 covering in the closed position half of the access opening 1, the opening 5 having, in the closed position, two free edges 9 ′, 9˝ central parallel to the pivot axes, in look at one of the other. The means 12 for adjusting the centering of the openings 5 relative to the frame 6 cooperate with the edges 10, 11 of the openings 5 which are perpendicular to the pivot axes, and more precisely with the part 21 of these edges 10, 11 of the opening 5 which is closest to the central edges 9 ′, 9˝ of the opening 5 ′, 5˝ coming opposite one another. The means 12 for adjusting the centering of the openings 5 ′, 5˝ relative to the frame 6 are integral with the crosspieces 6c, 6d of the frame 6, symmetrically arranged around the center 22c, 22d of each crosspiece 6c, 6d and close to this center 22c, 22d. The oblong openings 18 of articulation are also symmetrically arranged with respect to the center 22c, 22d of each crosspiece 6c, 6d.

Le mode de réalisation préférentiel représenté sur la figure concerne l'application de l'invention à un élément d'aménagement tel qu'un meuble d'atelier de rangement ou d'outils ou autres objets lourds déjà décrit en ce qui concerne ses caractéristiques générales dans la demande de brevet français 8606054. Ces caractéristiques générales ne seront donc pas décrites en détail dans la présente demande qui suppose connu l'enseignement de la demande de brevet français N° 8606054.The preferred embodiment shown in the figure relates to the application of the invention to a furnishing element such as a workshop workshop furniture or tools or other heavy objects already described with regard to its general characteristics. in French patent application 8606054. These general characteristics will therefore not be described in detail in the present application, which assumes that the teaching of French patent application No. 8606054 is known.

Chaque ouvrant 5 est généralement constitué d'une plaque au moins sensiblement plane, rectangulaire et métallique. L'un 5˝ de ces ouvrants est représenté en position de fermeture sur la figure. L'autre 5′ est représenté en position de semi-ouverture. L'articulation de chaque ouvrant 5 au dormant est réalisée grâce à deux bras coudés 13c, 13d articulés d'une part respectivement aux traverses 6c, 6d de l'encadrement et d'autre part à un boîtier 23 solidaire de la face interne de chaque ouvrant 5. De préférence, les deux bras 13c, 13d sont réalisés par une même tige coudée et donc, mécaniquement solidaires l'un de l'autre à travers le boîtier 23. L'un 5′ des ouvrants comporte des moyens spécifiques de manoeuvre 17 accessibles par les deux faces de l'ouvrant 5′, tandis que l'autre 5˝ ne comporte qu'un rebord 24 prolongeant parallèlement à son plan P3 le chant central 9˝, ce rebord 24 permettant le blocage de cet ouvrant 5˝ lorsque l'autre ouvrant 5′ est lui-même bloqué par des moyens 25 de blocage/déblocage solidaires de cet ouvrant 5′ et coopérant avec des moyens complémentaires 26 du dormant. Ces moyens 25 de blocage/déblocage sont commandés par une poignée 27 et un mécanisme à serrure appropriés.Each opening 5 generally consists of an at least substantially flat, rectangular and metallic plate. One 5˝ of these openings is shown in the closed position in the figure. The other 5 ′ is shown in the semi-open position. The articulation of each opening 5 to the frame is achieved by two bent arms 13c, 13d articulated on the one hand respectively to the crosspieces 6c, 6d of the frame and on the other hand to a housing 23 secured to the internal face of each opening 5. Preferably, the two arms 13c, 13d are produced by the same bent rod and therefore, mechanically integral with one another through the housing 23. One 5 ′ of the opening comprises specific means of operation 17 accessible by the two faces of the opening 5 ′, while the other 5˝ only has a rim 24 extending parallel to its plane P3 the central edge 9˝, this rim 24 allowing the locking of this opening 5˝ when the other opening 5 ′ is itself blocked by locking / unlocking means 25 integral with this opening 5 ′ and cooperating with complementary means 26 of the frame. These means 25 of locking / unlocking are controlled by a handle 27 and a suitable locking mechanism.

Un élément d'aménagement selon l'invention est caractérisé en ce qu'il comporte une ouverture d'accès 1 et un dispositif de fermeture de cette ouverture d'accès 1 selon l'invention. L'élément d'aménagement selon l'invention, qui peut être, par exemple, une armoire de stockage d'outils, comporte donc quatre roulettes 12 d'ajustement du centrage des ouvrants 5′, 5˝: deux roulettes 12c′, 12c˝ solidaires de la traverse supérieure 6c de l'encadrement 6 et coopérant respectivement avec les ouvrants 5′ et 5˝, et deux roulettes 12d′ et 12d˝, solidaires de la traverse inférieure 6d de l'encadrement 6 et coopérant également respectivement avec les ouvrants 5′ et 5˝. Ces roulettes 12 sont disposées le plus proche possible des centres 22c, 22d des traverses 6c, 6d, compte tenu de la présence des moyens 26 du dormant complémentaires des moyens 25 de blocage/déblocage des ouvrants 5. Ces roulettes 12 sont articulées autour d'axes de rotation 20 parallèles aux traverses 6c, 6d.An arrangement element according to the invention is characterized in that it comprises an access opening 1 and a device for closing this access opening 1 according to the invention. The arrangement element according to the invention, which can be, for example, a tool storage cabinet, therefore comprises four castors 12 for adjusting the centering of the opening elements 5 ′, 5˝: two casters 12c ′, 12c ˝ secured to the upper cross member 6c of the frame 6 and cooperating respectively with the openings 5 ′ and 5˝, and two rollers 12d ′ and 12d˝, secured to the lower cross member 6d of the frame 6 and also cooperating respectively with the opening 5 ′ and 5˝. These rollers 12 are arranged as close as possible to the centers 22c, 22d of the crosspieces 6c, 6d, taking into account the presence of the means 26 of the complementary frame of the means 25 for locking / unlocking the opening elements 5. These rollers 12 are articulated around axes of rotation 20 parallel to the crosspieces 6c, 6d.

L'élément d'aménagement 4 représenté sur la figure comporte un fond 28, parallèle à l'encadrement 6, et quatre parois planes dont deux 29a, 29b sont verticales tandis que deux autres 29c, 29d sont horizontales, pour former une caisse ouverte sensiblement parallélépipédique. Sur la figure, la paroi supérieure horizontale 29c n'est pas représentée, et ce pour mieux illustrer l'invention.The arrangement element 4 shown in the figure has a bottom 28, parallel to the frame 6, and four flat walls, two of which 29a, 29b are vertical while the other two 29c, 29d are horizontal, to form a substantially open box parallelepiped. In the figure, the horizontal upper wall 29c is not shown, to better illustrate the invention.

Les extrémités 19 des bras 13 d'articulation sont engagées dans des lumières 19 oblongues dans la direction parallèle à celle des traverses 6c, 6d. De la sorte, ces extrémités 19 peuvent branler avec jeu dans ses lumières. Bien entendu, il aurait aussi été possible de prévoir d'autres dispositions permettant le branlement de l'ouvrant 5 parallèlement au plan P1 de l'encadrement 6 en position de fermeture et dans les positions voisines de la position de fermeture. Les lumières 18c supérieures sont ménagées dans un renfoncement 30 en retrait vers l'espace intérieur 2 et vers le bas et s'étendent parallèlement à la traverse 6c, de sorte que les extrémités libres 19c des bras d'articulation supérieurs 13c ne saillent pas au-delà du plan horizontal supérieur défini par les chants libres supérieurs 31 des parois verticales 29a, 29b et du fond 28. Ainsi, les extrémités supérieures 19 ne viennent pas au contact de la paroi horizontale supérieure 29c. Au contraire, dans la partie inférieure, les lumières 18d recevant les extrémités libres 19d des bras inférieurs d'articulation 13d sont simplement ménagées directement dans la paroi horizontale inférieure 29d au voisinage de la traverse 6d.The ends 19 of the articulation arms 13 are engaged in slots 19 oblong in the direction parallel to that of the crosspieces 6c, 6d. In this way, these ends 19 can jerk with play in its lights. Of course, it would also have been possible to provide other arrangements allowing the opening of the opening 5 parallel to the plane P1 of the frame 6 in the closed position and in the positions close to the closed position. The upper slots 18c are formed in a recess 30 set back towards the interior space 2 and downwards and extend parallel to the cross-member 6c, so that the free ends 19c of the upper articulation arms 13c do not project at the beyond the upper horizontal plane defined by the upper free edges 31 of the vertical walls 29a, 29b and of the bottom 28. Thus, the ends upper 19 do not come into contact with the upper horizontal wall 29c. On the contrary, in the lower part, the openings 18d receiving the free ends 19d of the lower articulation arms 13d are simply arranged directly in the lower horizontal wall 29d in the vicinity of the cross-member 6d.

Les dimensions des roulettes 12 et de leurs axes 20 sont bien entendu adaptées en fonction du jeu possible des ouvrants 5, et des contraintes qu'elles doivent supporter. De préférence, ces roulettes 12 sont disposées légèrement vers l'intérieur 2 de l'élément d'aménagement 4, de sorte que ces roulettes 12 ne sont pas visibles de l'extérieur lorsque les ouvrants 5 sont en position de fermeture. Un cache peut être prévu pour recourir la traverse supérieure 6c, ou même la traverse inférieure 6d.The dimensions of the rollers 12 and their axes 20 are of course adapted as a function of the possible play of the openings 5, and of the constraints which they have to bear. Preferably, these rollers 12 are arranged slightly towards the inside 2 of the arrangement element 4, so that these rollers 12 are not visible from the outside when the opening elements 5 are in the closed position. A cover can be provided to use the upper cross member 6c, or even the lower cross member 6d.

Ainsi, l'élément d'aménagement 4 selon l'invention a ses ouvrants 5 parfaitement centrés et alignés, de niveau lorsqu'ils sont en position de fermeture. Ces ouvrants sont maintenus par les roulettes 12 d'ajustement du centrage. Cela confère un aspect esthétique meilleur à l'élément d'aménagement 4 selon l'invention, ainsi qu'une plus grande rigidité et une meilleure fiabilité et sécurité d'utilisation. On remarquera que l'invention est réalisée grâce à des éléments extrêmement peu coûteux.Thus, the arrangement element 4 according to the invention has its openings 5 perfectly centered and aligned, level when they are in the closed position. These opening elements are held by the wheels 12 for adjusting the centering. This gives a better aesthetic appearance to the furnishing element 4 according to the invention, as well as greater rigidity and better reliability and safety in use. It will be noted that the invention is achieved thanks to extremely inexpensive elements.

L'invention peut faire l'objet de nombreuses variantes et applications évidentes à l'homme du métier.The invention can be the subject of numerous variants and applications obvious to those skilled in the art.
