Description

DISPOSITIF DE PLAFOND TENDU.TENSIONED CEILING DEVICE.
La présente invention a pour objet un dispositif de plafond tendu .The present invention relates to a stretch ceiling device.
On sait qu'un plafond tendu consiste en un faux-plafond constitué d'une nappe tendue, dont les bords sont solidarisés, par l'intermédiaire de moyens de fixation réversibles, à une lisse se présentant sous la forme d'un cadre constitué de profilés aboutés, et solidarisé au plafond à équiper ou aux murs qui bordent celui-ci.We know that a stretch ceiling consists of a false ceiling made up of a stretched sheet, the edges of which are secured, by means of reversible fixing means, to a stringer in the form of a frame made of butted profiles, and secured to the ceiling to be fitted or to the walls which border it.
De manière traditionnelle, la nappe consiste en une feuille de matière plastique comportant le long de chacun de ses côtés une bordure d'accrochage également en matière plastique, qui présente en section le profil d'un crochet ou d'un harpon recourbé vers le bas, et qui est destinée à venir s'accrocher sur une lèvre d'accrochage que comporte le cadre.Traditionally, the tablecloth consists of a plastic sheet comprising along each of its sides a hooking edge also made of plastic, which has in section the profile of a hook or a harpoon bent downwards , and which is intended to come and hang on a hooking lip that the frame has.
L'accrochage de la nappe doit être réalisé de proche en proche en exerçant une poussée en direction du mur afin que la bordure en forme de crochet dépasse l'épaulement et puisse en retour s'y encliqueter .The hanging of the tablecloth must be carried out step by step by exerting a push towards the wall so that the hook-shaped border exceeds the shoulder and can in turn snap into it.
Cette opération, qui est généralement réalisée au moyen d'un outil du type spatule de faible largeur engagée dans la gorge de la bordure, est longue et pénible, d'autant que, pour des raisons esthétiques évidentes, la nappe doit être parfaitement tendue, ce qui est obtenu en la fabriquant dans des dimensions inférieures à celles de la surface à couvrir.This operation, which is generally carried out using a tool of the spatula type of small width engaged in the groove of the border, is long and painful, especially since, for obvious aesthetic reasons, the sheet must be perfectly stretched, which is obtained by manufacturing it in dimensions smaller than those of the surface to be covered.
On notera qu' afin de faciliter la pose de la nappe du fait de ces dimensions réduites, on élève la température de la pièce à équiper, en sorte de distendre ladite nappe pendant la durée de la pose. Il est également à noter que l'opération de pose est également relativement délicate, puisqu'il est possible d'endommager malencontreusement la nappe avec l'outil utilisé.It will be noted that in order to facilitate the laying of the sheet due to these reduced dimensions, the temperature of the part to be fitted is raised, so as to distend said sheet during the laying period. It should also be noted that the laying operation is also relatively delicate, since it is possible to inadvertently damage the sheet with the tool used.
Par ailleurs, il est parfois nécessaire, pour des raisons diverses, de remplacer la nappe par une autre. L'enlèvement d'une telle nappe ne pose pas de difficultés techniques particulières, par contre c'est une opération relativement longue puisqu'il faut également procéder de proche en proche.In addition, it is sometimes necessary, for various reasons, to replace the sheet with another. The removal of such a sheet does not pose any particular technical difficulty, on the other hand it is a relatively long operation since it is also necessary to proceed step by step.
Outre les inconvénients liés à la mise en place de la nappe sur le cadre et à son éventuel enlèvement, un plafond tendu tel que défini précédemment présente des inconvénients du point de vue de la fabrication de la nappe .In addition to the drawbacks linked to the placing of the ply on the frame and to its possible removal, a stretch ceiling as defined above has drawbacks from the point of view of the manufacture of the ply.
En effet, la nappe est réalisée par la juxtaposition et le soudage de lés, lesquels comportent, de fabrication, sur chacun de deux bords opposés , une bordure d' accrochage . Or , l'aboutement et le soudage des bordures d'accrochage de deux lés adjacents présentent des inconvénients nécessitant un outillage particulier .Indeed, the ply is produced by the juxtaposition and the welding of strips, which comprise, by manufacture, on each of two opposite edges, a fastening edge. However, the joining and welding of the attachment edges of two adjacent strips have drawbacks requiring special tools.
Enfin, du fait du mode de fixation utilisé, une partie du cadre demeure visible après la mise en place de la nappe ce qui nécessite de prévoir soit une lisse présentant un profil particulier, du type corniche par exemple, soit un élément de finition rapporté, destiné à venir recouvrir la région de jonction entre la nappe et le cadre. Une lisse de profil particulier ou un élément de finition rapporté doivent être d'une largeur relativement importante, ce qui, outre le surcoût engendré, peut nuire à l'esthétique.Finally, due to the method of attachment used, part of the frame remains visible after the ply has been put in place, which requires providing either a heddle having a particular profile, of the cornice type for example, or an added finishing element, intended to cover the junction region between the sheet and the frame. A smooth profile or an added finishing element must be of relatively large width, which, in addition to the additional cost, can affect the aesthetics.
La présente invention a pour objet de proposer un dispositif de plafond tendu permettant de remédier aux divers inconvénients précités. Le dispositif de plafond tendu objet de l'invention est du type comportant une nappe tendue dont les bords sont solidarisés , par l'intermédiaire de moyens de fixation réversibles, à un cadre lui-même solidarisé au plafond à équiper ou aux murs qui bordent celui-ci, et il se caractérise essentiellement en ce que lesdits moyens de fixation réversibles consistent en des moyens auto- agrippants constitués de deux parties solidarisées pour l'une en bordure de ladite nappe et pour l'autre sur ledit cadre, dont la mise en contact assure un ancrage de l'une à l'autre apte à assurer une résistance à la traction dans au moins un sens parallèle au plan de ladite nappe.The object of the present invention is to propose a stretch ceiling device making it possible to remedy the various aforementioned drawbacks. The stretch ceiling device object of the invention is of the type comprising a stretched sheet whose edges are secured, by means of reversible fixing means, to a frame itself secured to the ceiling to be fitted or to the walls which border that -this, and it is essentially characterized in that said reversible fixing means consist of hook-and-loop means consisting of two integral parts for one at the edge of said ply and for the other on said frame, the setting of which contact ensures anchoring from one to the other capable of ensuring tensile strength in at least one direction parallel to the plane of said ply.
La mise en place d'une telle nappe est très aisée, il suffit d' appliquer sans outil la partie des moyens auto-agrippants dont est muni le bord de ladite nappe contre l'autre partie dont est muni le cadre. Du point de vue pratique, la nappe est de préférence solidarisée au cadre par ses coins avant de fixer les bords, la réversibilité aisée de l'accrochage permettant d'affiner la fixation.The establishment of such a ply is very easy, it suffices to apply without tool the part of the hook-and-loop means with which the edge of said ply is provided against the other part with which the frame is provided. From a practical point of view, the sheet is preferably secured to the frame by its corners before fixing the edges, the easy reversibility of the attachment making it possible to refine the fixing.
De manière avantageuse, il est possible, par le dimensionnement de la nappe, de faire affleurer les bords de celle-ci avec les murs , en sorte qu' il est possible de recouvrir la ligne de jonction avec une simple petite baguette d'angle du type quart de rond.Advantageously, it is possible, by sizing the tablecloth, to make the edges of the latter flush with the walls, so that it is possible to cover the junction line with a simple small corner rod of the quarter round type.
Selon une caractéristique additionnelle du dispositif selon l'invention, les moyens de fixation sont du type velours- crochets .According to an additional characteristic of the device according to the invention, the fixing means are of the velvet-hook type.
Selon une autre caractéristique additionnelle du dispositif selon l'invention, le cadre consiste en un profilé du type cornière de section en L, dont une aile est destinée à être fixée sur un mur tandis que l'autre, perpendiculaire audit mur et positionnée en bas, reçoit sur sa face inférieure et longitudinalement l'une des deux parties des moyens auto- agrippants .According to another additional characteristic of the device according to the invention, the frame consists of a section of the L-shaped angle type, one wing of which is intended to be fixed to a wall while the other, perpendicular to said wall and positioned at the bottom. , receives on its underside and longitudinally one of the two parts of the hook-and-loop means.
Selon une autre caractéristique additionnelle du dispositif selon l'invention, la partie des moyens auto-agrippants solidarisée à la nappe, est assujettie à celle-ci par soudage.According to another additional characteristic of the device according to the invention, the part of the hook-and-loop means secured to the sheet, is subjected to the latter by welding.
Avantageusement, le soudage à la nappe de la partie des moyens auto-agrippants qui lui est destinée, est réalisé après l'opération d' aboutement et de soudage des différents lés qui la compose, en sorte que cette opération ne nécessite pas d'outillage particulier.Advantageously, the sheet welding of the part of the hook-and-loop means which is intended for it, is carried out after the operation of abutting and welding of the various strips which composes it, so that this operation does not require any tooling. particular.
Le dispositif de plafond tendu selon l' invention présente de nombreux avantages, que ce soit du point de vue de sa fabrication, ou de l'opération de pose, ce qui conduit à un coût bien inférieur à celui des produits existants .The stretch ceiling device according to the invention has many advantages, either from the point of view of its manufacture, or of the laying operation, which leads to a cost much lower than that of existing products.
Les avantages et les caractéristiques du dispositif selon l'invention, ressortiront plus clairement de la description qui suit et qui se rapporte au dessin annexé, lequel en représente un mode de réalisation non limitatif.The advantages and characteristics of the device according to the invention will emerge more clearly from the description which follows and which refers to the appended drawing, which represents a non-limiting embodiment thereof.
Dans le dessin annexé la figure unique représente une vue schématique partielle en coupe d'un dispositif de plafond tendu selon l'invention.In the accompanying drawing the single figure shows a partial schematic sectional view of a stretch ceiling device according to the invention.
Sur cette figure on peut voir un dispositif 1 de plafond tendu selon l'invention, destiné à être posé dans une pièce dont n'est représenté qu'un mur 2.In this figure we can see a stretch ceiling device 1 according to the invention, intended to be installed in a room of which only one wall 2 is represented.
Le dispositif 1 de plafond tendu selon l'invention comprend un cadre 3 et une nappe 4. Le cadre 3 est constitué de l'assemblage de profilés 30 du type cornière de section en L, dont une aile 31 est fixée au mur 2 par des moyens appropriés, non représentés, tandis que son autre aile 32 s'étend perpendiculairement au mur 2, en dessous de l'aile 31.The stretch ceiling device 1 according to the invention comprises a frame 3 and a ply 4. The frame 3 consists of the assembly of profiles 30 of the L-section angle type, one wing 31 of which is fixed to the wall 2 by appropriate means, no shown, while its other wing 32 extends perpendicular to the wall 2, below the wing 31.
La nappe 4 consiste de manière connue en une feuille de matière plastique présentant une certaine élasticité pour sa mise en plac .The ply 4 consists in a known manner of a sheet of plastic material having a certain elasticity for its positioning.
Selon l'invention, la solidarisation de la nappe 4 au cadre 3 est réalisée par l'intermédiaire d'un moyen 5 de fixation réversible constitué de deux parties 50 et 51 solidaires chacune, respectivement, du cadre 3 et de la nappe 4, et qui sont du type auto-agrippant , c'est-à-dire aptes à assurer un ancrage lors de leur mise en contact.According to the invention, the connection of the sheet 4 to the frame 3 is carried out by means of a reversible fixing means 5 consisting of two parts 50 and 51 each secured, respectively, to the frame 3 and the sheet 4, and which are of the hook-and-loop type, that is to say capable of ensuring anchoring when brought into contact.
Les parties 50 et 51 sont du type velours-crochets, se présentant sous la forme de bandes, l'une fixée, par collage par exemple, sous l'aile 32 du profilé 30, et l'autre fixée, par soudage par exemple, sur le bord la nappe 3.The parts 50 and 51 are of the velvet-hook type, in the form of strips, one fixed, for example by gluing, under the wing 32 of the profile 30, and the other fixed, by welding for example, on the edge of the tablecloth 3.
La fixation procurée par le moyen auto-agrippant 5 assure une excellente résistance au cisaillement, il est de plus aisément réversible ce qui est très utile lors de la pose de la nappe 3 pour réajuster celle-ci, ou pour son enlèvement.The fixing provided by the self-gripping means 5 ensures excellent shear strength, it is more easily reversible which is very useful when laying the ply 3 to readjust it, or for its removal.
On notera que le cadre peut être constitué de profilés présentant des sections différentes de celle représentée, chacun adapté à une application particulière pour, par exemple fixer le cadre directement au plafond.It will be noted that the frame can be made up of profiles having sections different from that shown, each adapted to a particular application for, for example fixing the frame directly to the ceiling.
II est également possible d'envisager de fixer l'une des deux parties 50 ou 51 du moyen auto-agrippant 5 directement sur le plafond, dans ce cas par cadre il convient d'entendre la zone périphérique du plafond ayant subit une préparation de surface pour permettre la fixation par collage par exemple. It is also possible to envisage fixing one of the two parts 50 or 51 of the hook-and-loop means 5 directly on the ceiling, in this case by frame it is necessary to hear the peripheral zone of the ceiling having undergone a surface preparation to allow fixing by gluing for example.
