Description

CAISSON LUMINEUX A OUVERTURE COMPAS A RESSORT LUMINOUS CABINET WITH SPRING COMPASS OPENING
La présente invention concerne un caisson articulé de préférence lumineux à cadre interne mobile. Ce caisson lumineux est destiné à être fixé sur une paroi, telle qu'un mur ou un plafond. II comprend un cadre interne muni d'une nappe tendue fixée à la base dudit cadre interne, une enveloppe destinée à être fixée à une paroi et comportant un cadre externe et un fond, et un ensemble charnière reliant le cadre interne et l'enveloppe de manière à permettre un basculement dudit cadre interne par rapport à l'enveloppe du caisson.The present invention relates to a hinged box preferably bright with movable internal frame. This light box is intended to be fixed on a wall, such as a wall or a ceiling. It comprises an inner frame provided with a stretched sheet attached to the base of said inner frame, an envelope intended to be fixed to a wall and comprising an outer frame and a bottom, and a hinge assembly connecting the inner frame and the outer casing. so as to allow a tilting of said inner frame relative to the casing of the box.
En particulier, l'enveloppe peut être équipée de moyens d'éclairage et la nappe peut être de type translucide. Le caisson peut encore comprendre, de manière connue, des éléments raidisseurs pour renforcer sa rigidité.In particular, the envelope may be equipped with lighting means and the sheet may be of translucent type. The box may further comprise, in a known manner, stiffening elements to reinforce its rigidity.
Pour permettre les opérations de maintenance, tant de la face interne de la nappe tendue (nettoyage) que celle des moyens d'éclairage (nettoyage et échange des tubes fluorescents par exemple) , le cadre interne est monté pivotant sur l'enveloppe du caisson.To allow maintenance operations, both the inner face of the stretched web (cleaning) and that of the lighting means (cleaning and exchange of fluorescent tubes for example), the inner frame is pivotally mounted on the casing of the box.
Une articulation du cadre interne par rapport à l'enveloppe est connue notamment du document FR 2 911 619. Toutefois, l'articulation, qui comprend une première partie montée sur une face dudit cadre interne en regard du fond de l'enveloppe et une deuxième partie montée sur ledit fond, les première et deuxième parties étant montées pivotantes l'une par rapport à l'autre, présente plusieurs inconvénients. Ainsi, la fixation de la deuxième partie sur ledit fond rend la mise en place et la maintenance délicates. En outre, cette articulation ne possède pas de moyens de blocage permettant d' immobiliser le cadre interne quelque soit sa position d'ouverture, ce qui peut être dangereux car ledit cadre interne peut tomber d'un seul coup, lorsque l'on déverrouille les loquets de fixation qui le maintiennent en position fermée, en risquant ainsi de blesser l'opérateur venu réaliser la maintenance. Enfin, il est prévu des moyens, qui peuvent être constitués par un fil souple, une sangle ou une chainette, pour maintenir le cadre interne dans une position ouverte inclinée, ces moyens peuvent être une entrave lors des opérations de maintenance et de la fermeture du caisson lumineux. La présente invention a pour but de proposer une solution plus simple, plus sûre et plus efficace pour le basculement du caisson.An articulation of the internal frame with respect to the envelope is known in particular from document FR 2 911 619. However, the articulation, which comprises a first portion mounted on one face of said inner frame facing the bottom of the envelope and a second portion mounted on said bottom, the first and second parts being pivotally mounted relative to each other, has several disadvantages. Thus, fixing the second part on said bottom makes setting up and maintaining delicate. In addition, this joint does not have locking means for immobilizing the internal frame whatever its open position, which can be dangerous because said internal frame can fall at once, when unlocking the latches that hold it in the closed position, thus risking injury to the operator who came to perform maintenance. Finally, there are provided means, which may be constituted by a flexible wire, a strap or a chain, to maintain the internal frame in an inclined open position, these means may be an obstacle during maintenance operations and the closure of the light box. The present invention aims to provide a simpler, safer and more effective solution for tilting the box.
A cet effet, il est proposé un caisson articulé, notamment pour faux plafond, comprenant : - une enveloppe comportant un cadre, dit cadre externe, formé de quatre côtés définissant un quadrilatère sur lesquels est monté un fond, destinée à être fixée à une paroi,For this purpose, it is proposed an articulated box, especially for false ceiling, comprising: - an envelope comprising a frame, said outer frame formed of four sides defining a quadrilateral on which is mounted a bottom, intended to be fixed to a wall ,
- un cadre interne formé de quatre profilés à la base desquels est fixée une nappe tendue,an internal frame formed of four profiles at the base of which is fixed a stretched sheet,
- au moins une articulation reliant ledit cadre interne et ladite enveloppe de manière à permettre un basculement dudit cadre interne par rapport à ladite enveloppe et, - au moins une fermeture pour maintenir le cadre interne en position de fermeture, dite de fonctionnement, ledit cadre interne étant monté coulissant sur 1' articulation.at least one hinge connecting said inner frame and said casing so as to allow said inner frame to tilt relative to said casing and, at least one closure to hold the internal frame in the closed position, said operating position, said internal frame being slidably mounted on the hinge.
Ledit caisson articulé est remarquable en ce que l'articulation est du type à freinage permettant d' immobiliser le cadre interne en toute position basculée et comporte un ensemble charnière comprenant une plaquette, une bride, un mécanisme déformable de type quadrilatère déformable composé de deux bielles articulées et un moyen de freinage, lesdites bielles et ledit moyen de freinage sont articulés à l'une de leurs extrémités à la plaguette et à l'autre à la bride.Said articulated box is remarkable in that the articulation is of the braking type for immobilizing the internal frame in any tilted position and comprises a hinge assembly comprising a plate, a flange, a deformable mechanism of deformable quadrilateral type consisting of two connecting rods articulated and a way braking, said connecting rods and said braking means are articulated at one of their ends to the fly and the other to the flange.
Cet agencement permet une mise en œuvre facile et une maintenance sécurisée du caisson articulé, en effet, le fait de pouvoir immobiliser le cadre interne en toute position basculée permet de ne pas munir ledit caisson de moyen de retenue et d'éviter une chute intempestive du cadre interne qui pourrait blesser un opérateur de maintenance ou endommager le caisson si un objet de grande hauteur est placé en-dessous.This arrangement allows easy implementation and secure maintenance of the articulated box, indeed, the fact of being able to immobilize the internal frame in any tilted position makes it possible not to provide said box with a holding means and to avoid an inadvertent fall of internal frame that could hurt a maintenance operator or damage the box if a high-rise object is placed underneath.
Avantageusement, l'ensemble charnière est solidaire du cadre externe de l'enveloppe du caisson.Advantageously, the hinge assembly is integral with the outer frame of the casing of the box.
On décrira ci-après à titre d'exemple non limitatif, une forme d'exécution de la présente invention, en référence au dessin annexé sur lequel :One embodiment of the present invention will be described hereinafter by way of nonlimiting example, with reference to the appended drawing in which:
- la figure 1 est une coupe verticale d'un caisson articulé en position de fermeture, ou position de fonctionnement , - la figure 2 est une coupe verticale d'un caisson articulé en position d'ouverture, ou position de maintenance,- Figure 1 is a vertical section of a hinged box in the closed position, or operating position, - Figure 2 is a vertical section of a hinged box in the open position, or maintenance position,
- la figure 3 illustre un mode de réalisation de l'ensemble charnière en position ouverture. On a représenté sur les figures 1 et 2 un caisson articulé 1, selon l'invention, comportant une enveloppe 2 destinée à recevoir un cadre interne 3 mobile.- Figure 3 illustrates an embodiment of the hinge assembly in the open position. FIGS. 1 and 2 show an articulated box 1, according to the invention, comprising an envelope 2 intended to receive an internal mobile frame 3.
Dans cette description, on suppose que le dispositif à caisson est fixé à un plafond. Les expressions "supérieure" et "inférieure" utilisées ici se rapportent donc à des positions relatives par rapport au sens vertical. Plus généralement, par exemple dans le cas d'un dispositif à caisson fixé à un mur, il convient d'interpréter "supérieure" et "inférieure" respectivement - A - dans le sens "en regard du fond (ou proche du fond) " et "éloigné du fond".In this description, it is assumed that the box device is attached to a ceiling. The terms "upper" and "lower" used herein, therefore, refer to positions relative to the vertical direction. More generally, for example in the case of a box device attached to a wall, it is appropriate to interpret "upper" and "lower" respectively - A - in the direction "opposite the bottom (or near the bottom)" and "away from the bottom".
Le cadre interne 3 est, en fonctionnement, logé dans l'enveloppe 2 du caisson 1, comme représenté sur la figure 1 et est, notamment pour la maintenance, basculé hors de l'enveloppe 2, comme représenté sur la figure 2.The internal frame 3 is, in operation, housed in the casing 2 of the casing 1, as shown in FIG. 1 and is, in particular for maintenance, tilted out of the casing 2, as represented in FIG.
L'enveloppe 2 comprend un cadre, dit cadre externe 4, formé de quatre côtés 5, définissant un quadrilatère, sur lesquels est monté un fond 6. Cette enveloppe 2 est destinée à être fixée à une paroi, telle qu'un mur ou un plafond comme dans cet exemple. Le cadre interne 3 est formé de quatre profilés 7 à la base desquels est fixée une nappe tendue 8.The envelope 2 comprises a frame, said outer frame 4, formed of four sides 5, defining a quadrilateral, on which is mounted a bottom 6. This envelope 2 is intended to be fixed to a wall, such as a wall or a wall. ceiling as in this example. The internal frame 3 is formed of four sections 7 at the base of which is attached a stretched sheet 8.
Comme représenté sur les figures 1 et 2, le cadre interne 3 peut être équipé d'une seconde nappe tendue 9 située au-dessus de la première nappe tendue 8. Par exemple, la première nappe tendue 8 est translucide et la deuxième nappe tendue 9 est transparente. La deuxième nappe tendue 9 a notamment pour rôle de protéger la première nappe tendue 8 contre les poussières et les insectes qui pourraient se déposer sur celle-ci et qui seraient visibles par les usagers.As shown in FIGS. 1 and 2, the inner frame 3 may be equipped with a second stretched sheet 9 situated above the first stretched sheet 8. For example, the first stretched sheet 8 is translucent and the second sheet is stretched 9 is transparent. The second stretched sheet 9 has the role of protecting the first stretched sheet 8 against dust and insects that could be deposited on it and which would be visible by users.
Dans un mode de réalisation préférentiel, le caisson articulé 1 comprend en outre des moyens raidisseurs (non représentés) pour rigidifier le cadre interne 3 formés d'au moins un longeron s ' étendant entre deux profilés 7 opposés du cadre interne 3 du caisson articulé 1. Il comprend encore des moyens d'éclairage, tels que des tubes néons 10, avantageusement montés sur le fond 6. Le cadre interne 3 est apte à basculer par rotation autour d'un axe parallèle à l'un des côtés du caisson articulé 1. Pour maintenir le cadre interne 3 en position de fermeture dite de fonctionnement, le caisson articulé 1 comporte au moins une fermeture 11. Cette fermeture 11 est de préférence de type à encliquetage . Ainsi, pour déverrouiller ladite fermeture 11 et donc ouvrir le caisson articulé 1, on exerce une impulsion sur le cadre interne 3 en direction du fond 6 de l'enveloppe 2 et pour verrouiller ladite fermeture 11 et donc fermer le caisson articulé 1, on exerce une impulsion semblable à la précédente. Ce type de fermeture 11 ne nécessite ni de poignée ni d'outillage pour sa manipulation, ce qui rend son utilisation simple et renforce l'aspect esthétique du caisson articulé 1. Pour assurer le mouvement de rotation du cadre interne 3, une articulation 12, relie le cadre interne 3 à l'enveloppe 2. Cette articulation 12 est du type à freinage c'est-à-dire qu'elle permet d'immobiliser le cadre interne 3 en toute position basculée. On a représenté sur la figure 3 un mode de réalisation préférentiel de ladite articulation 12. En pratique, le caisson articulé 1 comporte deux articulations 12 disposées sur des profilés 7 opposés du cadre interne 3 et définissant l'axe de rotation du cadre interne 3. Chaque articulation 12 comprend un ensemble charnière 13, un sabot 14 et ^n organe de coulissement 15.In a preferred embodiment, the articulated box 1 further comprises stiffening means (not shown) for stiffening the inner frame 3 formed of at least one spar extending between two sections 7 opposite the inner frame 3 of the articulated box 1 It also comprises lighting means, such as neon tubes 10, advantageously mounted on the bottom 6. The inner frame 3 is able to swing by rotation about an axis parallel to one of the sides of the articulated box 1 In order to maintain the internal frame 3 in the so-called operating closing position, the articulated box 1 comprises at least one closure 11. This closure 11 is preferably snap type. Thus, to unlock said closure 11 and thus open the articulated box 1, it exerts a pulse on the inner frame 3 towards the bottom 6 of the casing 2 and to lock said closure 11 and thus close the articulated box 1, it is used a pulse similar to the previous one. This type of closure 11 does not require any handle or tools for its handling, which makes its use simple and enhances the aesthetic appearance of the articulated box 1. To ensure the rotational movement of the inner frame 3, a hinge 12, connects the inner frame 3 to the casing 2. This hinge 12 is of the braking type that is to say that it allows to immobilize the inner frame 3 in any tilted position. FIG. 3 shows a preferred embodiment of said hinge 12. In practice, the hinged box 1 comprises two hinges 12 arranged on opposite sections 7 of the internal frame 3 and defining the axis of rotation of the internal frame 3. Each hinge 12 comprises a hinge assembly 13, a shoe 14 and a sliding member 15.
L'ensemble charnière 13 comprend une plaquette 131 fixée, par exemple, par une pluralité de vis sur la face interne d'un des cotés 5 de l'enveloppe 2, une bride 132 en forme générale de L fixée, par exemple, par une pluralité de vis sur le sabot 14, un mécanisme déformable de type quadrilatère déformable composé de deux bielles 133, 134 et un moyen de freinage 135. Lesdites bielles 133, 134 et ledit moyen de freinage 135 sont articulés à l'une de leur extrémité à la plaquette 131 et à l'autre à la bride 132 de sorte que la déformation du quadrilatère constitué par les deux bielles 133, 134 permet l'ouverture ou la fermeture de l'ensemble charnière 13.The hinge assembly 13 comprises a plate 131 fixed, for example, by a plurality of screws on the internal face of one of the sides 5 of the casing 2, a flange 132 in the general shape of an L fixed, for example, by a plurality of screws on the shoe 14, a deformable mechanism of the deformable quadrilateral type composed of two connecting rods 133, 134 and a braking means 135. Said connecting rods 133, 134 and said braking means 135 are articulated at one of their end to the plate 131 and the other at the flange 132 so that the deformation of the quadrilateral formed by the two connecting rods 133, 134 allows the opening or closing of the hinge assembly 13.
Le moyen de freinage 135 est avantageusement un ressort hélicoïdal que l'on pourra tarer en fonction notamment du poids du cadre interne 3. Ce moyen de freinage 135 exerce un effort de traction entre la plaquette 131 et la bride 132 tendant à les rapprocher de manière à immobiliser en toute position le mécanisme déformable composé de deux bielles 133, 134. On évite ainsi une ouverture brutale intempestive du cadre interne 3.The braking means 135 is advantageously a helical spring that can be tapped according to the weight of the inner frame 3. This braking means 135 exerts a tensile force between the plate 131 and the flange 132 tending to bring them together so as to immobilize in any position the deformable mechanism composed of two connecting rods 133, 134. This avoids a sudden untimely opening of the inner frame 3.
Il va de soi que le moyen de freinage 135 peut être de tout autre type connu procurant de effets similaires, tel que, par exemple, un vérin, sans pour autant sortir du cadre de l'invention.It goes without saying that the braking means 135 may be of any other known type providing similar effects, such as, for example, a jack, without departing from the scope of the invention.
Le sabot 14 est avantageusement un profilé en alliage léger tel qu'un alliage d'aluminium de forme globalement tubulaire dont la section a une forme générale de carré. Le sabot 14 comporte en outre une rainure 141 longitudinale en forme globale de T sur sa face externe, qui est en contact avec le dessus du profilé 7 du cadre interne 3 sur lequel il est disposé.The shoe 14 is advantageously a light alloy profile such as an aluminum alloy of generally tubular shape whose section has a generally square shape. The shoe 14 further comprises a longitudinal groove 141 in the overall shape of T on its outer face, which is in contact with the top of the profile 7 of the inner frame 3 on which it is arranged.
Ledit profilé 7 comporte également une rainure 71 longitudinale en forme globale de T inversé sur sa face supérieure et située en regard de la rainure 141 du sabot 14.Said section 7 also comprises a longitudinal groove 71 in the overall shape of an inverted T on its upper face and located facing the groove 141 of the shoe 14.
Le moyen de coulissement 15, qui est de préférence un profilé en alliage léger tel qu'un alliage d'aluminium dont la section a une forme générale de I, est apte à coopérer simultanément avec la rainure 141 du sabot 14 et la rainure 71 du profilé 7, de manière à permettre le coulissement du sabot 14 le long du profilé 7. De plus, le moyen de coulissement 15 est dimensionné de telle sorte qu' il permette un coulissement du sabot 14 le long du profilé 7 sans rupture du contact entre lesdits sabot 14 et profilé 7.The sliding means 15, which is preferably a light alloy profile such as an aluminum alloy whose section has a general shape of I, is able to cooperate simultaneously with the groove 141 of the shoe 14 and the groove 71 of the section 7, so as to allow the sliding of the shoe 14 along the profile 7. In addition, the sliding means 15 is dimensioned so that it allows a sliding of the shoe 14 along the section 7 without breaking the contact between said shoe 14 and profile 7.
On comprend bien que, compte tenu de la cinématique de l'ensemble charnière 13, il est primordial d'avoir une possibilité de coulissement du cadre interne 3 par rapport à l'articulation 12 par le biais du moyen de coulissement 15 afin de ne pas avoir un jeu trop important entre ledit cadre interne 3 et l'enveloppe 2 et ainsi, de ne pas nuire à l'esthétique du caisson articulé 1 selon l'invention. Ce coulissement est d'autant plus nécessaire dans le cas où l'on souhaite avoir une étanchéité entre le cadre interne 3 et l'enveloppe 2 en mettant en place un joint par exemple sous forme de balais sur le pourtour du cadre interne 3.It is understood that, given the kinematics of the hinge assembly 13, it is essential to have a possibility of sliding of the inner frame 3 with respect to the hinge 12 by means of the sliding means 15 in order not to have a too large clearance between said inner frame 3 and the casing 2 and thus not to harm the aesthetics of the articulated box 1 according to the invention. This sliding is all the more necessary in the case where it is desired to have a seal between the inner frame 3 and the casing 2 by putting in place a seal, for example in the form of brushes around the periphery of the internal frame 3.
Ainsi avec une configuration telle que décrite précédemment, pour ouvrir le caisson articulé 1 selon l'invention, on appuie sur le cadre interne 3 en direction du fond 6 jusqu'au déverrouillage de la fermeture 11 puis on tire sur ledit cadre interne 3 vers le bas pour le basculer et obtenir l'ouverture souhaitée. De façon analogue, pour fermer le caisson articulé 1, on repousse le cadre interne 3 vers le haut jusqu'au verrouillage de la fermeture 11. Enfin, il va de soi que l'exemple de caisson articulé conforme à l'invention qui vient d'être décrit n'est qu'une illustration particulière, en aucun cas limitative de 1 ' invention. Thus with a configuration as described above, to open the articulated casing 1 according to the invention, is pressed on the inner frame 3 in the direction of the bottom 6 to unlock the closure 11 and then draws on said inner frame 3 to the down to rock it and get the desired opening. Similarly, in order to close the articulated box 1, the inner frame 3 is pushed upwards until locking of the closure 11. Finally, it goes without saying that the example of an articulated box according to the invention which comes from To be described is only a particular illustration, in no way limiting of the invention.
