Description
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.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.
Il 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.It comprises an internal 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
On connaît également, dans des domaines techniques voisins, des mécanismes permettant un blocage en position d'un élément. Ainsi, le modèle d'utilité
La présente invention a pour but de proposer une solution plus simple, plus sûre et plus efficace pour le basculement du caisson.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,
- un cadre interne formé de quatre profilés à la base desquels est fixée une nappe tendue,
- 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,
- 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,
- an internal frame consisting of four profiles at the base of which is fixed a stretched sheet,
- at least one hinge connecting said inner frame and said casing so as to allow tilting of said inner frame with respect to said casing and,
- at least one closure to maintain the internal frame in the closed position, said operating,
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 plaquette 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 deformable quadrilateral type mechanism consisting of two connecting rods articulated and a braking means, said connecting rods and said braking means are articulated at one of their ends to the plate and the other to the flange.
Cet agencement permet une mise en oeuvre 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 :

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 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 in the direction "facing the bottom (or near the bottom)" and "remote the bottom".
Le cadre interne 3 est, en fonctionnement, logé dans l'enveloppe 2 du caisson 1, comme représenté sur la
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
Comme représenté sur les
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.In a preferred embodiment, the articulated box 1 further comprises stiffening means (not shown) for stiffening the
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.The
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.To ensure the rotational movement of the
On a représenté sur la
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
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
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
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.
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
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
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.Thus with a configuration as described above, to open the articulated casing 1 according to the invention, is pressed on the
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 l'invention.Finally, it goes without saying that the example of articulated box according to the invention which has just been described is only a particular illustration, in no way limiting the invention.
