Description
La présente invention propose une suspente de plafond pour suspendre les faux-plafonds à une paroi de plafond.The present invention provides a ceiling hanger for suspending false ceilings to a ceiling wall.
La suspente de plafond présente usuellement une tige et une extrémité de liaison. La tige est généralement méplate, et elle est destinée à être fixée dans la paroi de plafond, par exemple clouée sur des poutres, tandis que l'extrémité de liaison est reliée à un rail, ou profilé en U, dénommé encore fourrure. Aussi, des alignements de suspentes sont réalisés dans la paroi de plafond de manière à porter leur extrémité de liaison dans un même plan horizontal. Quant au profilé en U, il présente deux ailes étendues en regard l'une de l'autre, lesquelles ailes présentent une bordure d'aile terminée par un bord libre replié vers l'intérieur de l'espace compris entre les deux ailes de manière à former un rebord. En outre, les bordures d'aile sont recourbées l'une vers l'autre, en demeurant espacées l'une de l'autre et en définissant une ouverture, de telle sorte que les rebords s'étendent dans des sens opposés l'un de l'autre. Par ailleurs, l'extrémité de liaison des suspentes alignées présente deux portées d'appui latérales en retour par rapport à la tige. Ainsi, les portées d'appui des suspentes sont orientées vers la paroi de plafond tandis que les profilés en U sont engagés sur les extrémités de liaison, leur ouverture en direction de la paroi de plafond également, et leurs bordures d'aile recourbées respectivement en appui sur les portées d'appui latérales en retour. Une pluralité de profilés en U sensiblement parallèle entre eux, est alors accrochée à la paroi de plafond par l'intermédiaire d'une pluralité d'alignement de suspentes. Les profilés en U sont aussi ajustés dans un même plan grâce au positionnement des extrémités de liaison.The ceiling hanger usually has a rod and a connecting end. The rod is generally flat, and it is intended to be fixed in the ceiling wall, for example nailed to the beams, while the connecting end is connected to a rail, or U-shaped, still called fur. Also, lines of lines are made in the ceiling wall so as to bring their connecting end in the same horizontal plane. As for the U-shaped profile, it has two wings extended facing one another, which wings have a wing edge ending with a free edge folded inwardly of the space between the two wings so to form a rim. In addition, the wing edges are bent toward each other, remaining spaced from one another and defining an opening, so that the flanges extend in opposite directions. the other. Furthermore, the connecting end of the aligned lines has two lateral bearing surfaces in return with respect to the rod. Thus, the support surfaces of the lines are oriented towards the ceiling wall while the U-shaped sections are engaged on the connecting ends, their opening towards the ceiling wall as well, and their wing edges curved respectively in support on the lateral bearing surfaces in return. A plurality of U-shaped sections substantially parallel to each other, is then hooked to the ceiling wall through a plurality of line alignment. The U-shaped profiles are also adjusted in the same plane thanks to the positioning of the connection ends.
Les suspentes auxquelles sont accrochés les profilés en U, présentent une résistance en traction limitée au poids du faux-plafond et affectée d'un coefficient multiplicatif de sécurité. C'est bien plutôt la liaison entre l'extrémité de liaison et le profilé en U qui est vulnérable et on observe dans certaines circonstances, à une désolidarisation du profilé et de la suspente, notamment lorsque la charge du faux-plafond est importante. De surcroît, lorsque le profilé en U est mal ajusté sur l'extrémité de liaison, le poids du faux-plafond tend à provoquer la déformation puis l'écartement des bordures d'aile recourbées qui échappent alors aux portées d'appui en retour.The lines to which the U-profiles are hung, have a tensile strength limited to the weight of the false ceiling and assigned a multiplicative safety coefficient. It is rather the connection between the connecting end and the U-shaped section is vulnerable and in certain circumstances, there is a separation of the profile and the hanger, especially when the load of the false ceiling is important. In addition, when the profile U-shaped is poorly fitted on the connecting end, the weight of the false ceiling tends to cause the deformation and then the spacing of curved wing edges which then escape the bearing staves back.
Il a déjà été imaginé de limiter le mouvement relatif des profilés en U et des extrémités de liaison, non pas pour renforcer leur liaison mais pour atténuer les vibrations du profilé en U par rapport aux suspentes. On pourra notamment se référer au document
Aussi, un problème qui se pose et que vise à résoudre la présente invention est de proposer une suspente qui permette un meilleur accrochage du profilé en U à son extrémité de liaison.Also, a problem that arises and that aims to solve the present invention is to provide a hanger that allows better attachment of the U-shaped section at its connecting end.
Dans le but de résoudre ce problème, la présente invention propose une suspente de plafond destinée à accrocher un profilé en U à une paroi de plafond pour suspendre un faux-plafond. Ledit profilé en U présente deux ailes en regard et un espace intérieur délimité par lesdites deux ailes, lesdites ailes présentant respectivement une bordure terminée par un bord libre, ledit bord libre étant replié vers ledit espace intérieur pour former un rebord et lesdites bordures sont recourbées l'une vers l'autre, tandis que lesdits rebords s'étendent à l'opposé l'un de l'autre. Ladite suspente, quant à elle, présente une tige destinée à être fixée dans ladite paroi de plafond et une extrémité de liaison apte à venir en prise dans ledit espace intérieur dudit profilé en U, ladite extrémité de liaison présentant deux portées d'appui latérales en retour par rapport à ladite tige et opposées l'une de l'autre, les portées d'appui latérales étant destinées à recevoir en appui respectivement lesdites bordures recourbées dudit profilé en U. Selon l'invention, lesdites portées d'appui latérales présentent respectivement un ergot en retour, les ergots en retour desdites portées d'appui latérales étant destinés à venir respectivement en prise dans lesdits rebords opposés pour interdire le mouvement relatif dudit profilé en U et de ladite extrémité de liaison. Au surplus, toujours selon l'invention, ladite extrémité de liaison présente des languettes déformables destinées à venir s'étendre respectivement en regard desdites portées d'appui latérales, lesdites languettes déformables étant déformables entre une position écartée desdites portées d'appui latérales et une position rapprochée desdites portées d'appui latérales de manière à venir s'appuyer contre les bordures recourbées l'une vers l'autre de façon à prendre lesdites bordures recourbées entre lesdites portées d'appui latérales et les languettes déformables pour interdire ainsi le mouvement relatif dudit profilé en U et de ladite extrémité de liaison.In order to solve this problem, the present invention provides a ceiling hanger for hanging a U-profile to a ceiling wall for suspending a false ceiling. Said U-shaped section has two facing wings and an interior space delimited by said two wings, said wings respectively having a border terminated by a free edge, said free edge being folded towards said interior space to form a rim and said edges are curved l towards each other, while said flanges extend opposite each other. Said hanger, meanwhile, has a rod intended to be fixed in said ceiling wall and a connecting end adapted to engage in said interior space of said U-shaped section, said connecting end having two lateral bearing surfaces in return relative to said rod and opposed to each other, the lateral bearing surfaces being intended to receive respectively bearing said curved edges of said U-shaped section. According to the invention, said lateral bearing surfaces present respectively a lug in return, the lugs in return of said lateral bearing surfaces being intended to respectively engage in said opposite flanges to prohibit the relative movement of said U-shaped section and said connecting end. In addition, still according to the invention, said connecting end has deformable tabs intended to extend respectively opposite said lateral bearing surfaces, said deformable tongues being deformable between a position spaced apart from said lateral bearing surfaces and a position close to said lateral bearing surfaces so as to bear against the curved edges towards each other so as to take said curved edges between said lateral bearing surfaces and the deformable tabs to thereby prohibit the relative movement of said U-shaped section and said connecting end.
Ainsi, une caractéristique de l'invention réside dans la mise en oeuvre des languettes déformables. Lorsqu'elles sont dans ladite position écartée des portées d'appui latérales, il n'y a aucune difficulté à engager des extrémités de liaison dans l'espace intérieur du profilé en U et de venir porter précisément les portées d'appui latérales contre les bordures recourbées et encore plus précisément, les ergots en arrière des rebords.Thus, a feature of the invention lies in the implementation of the deformable tongues. When in said spaced apart position of the lateral bearing surfaces, there is no difficulty in engaging connecting ends in the interior space of the U-shaped section and in precisely bringing the lateral bearing surfaces against the curved borders and even more precisely, the lugs behind the edges.
Une autre caractéristique avantageuse de l'invention réside dans la mise en oeuvre d'ergots qui s'étendent en saillie des portées d'appui et dans le mode de coopération de ces ergots avec les rebords des bordures recourbées. En effet, les rebords des bordures recourbées forment des épaulements d'appui opposés contre lesquelles les ergots sont susceptibles de venir en butée latéralement, ce qui bloque en translation le mouvement des bordures recourbées selon une direction parallèle aux portées d'appui. De la sorte, l'écartement latéral des bordures recourbées, l'une de l'autre, est interdit quelque soit la charge supportée par le profilé en U. En conséquence, l'accrochage du profilé en U est assuré.Another advantageous feature of the invention lies in the implementation of lugs which protrude from the bearing surfaces and in the mode of cooperation of these lugs with the edges of the curved edges. Indeed, the edges of the curved edges form opposite bearing shoulders against which the lugs are likely to come into abutment laterally, which blocks in translation the movement of curved edges in a direction parallel to the bearing surfaces. In this way, the lateral spacing of the curved edges, one of the other, is prohibited regardless of the load supported by the U-shaped section. As a result, the U-shaped section is secured.
Ensuite, les languettes déformables sont aptes à être déformées à force, et notamment à être entraînées en pivotement pour venir dans une position rapprochée et en regard des portées d'appui latérales de manière à venir s'appuyer contre les bordures recourbées l'une vers l'autre, du côté de leur face opposée à l'espace intérieur. Ainsi, les bordures recourbées sont en prise entre les portées d'appui latérales et les languettes déformables, déformées. Aussi, les bordures recourbées sont alors prisonnières de l'extrémité de liaison, car leur mouvement vertical est alors interdit, et le rebord ne peut plus être engagé par dessus l'ergot, comme on l'expliquera en détail ci-après. Par conséquent, les deux bordures recourbées l'une vers l'autre sont prisonnières des portées d'appui latérales et le profilé en U est alors verrouillé sur l'extrémité de liaison.Then, the deformable tongues are adapted to be deformed by force, and in particular to be pivoted to come in a close position and facing the lateral bearing surfaces so as to come to rest against the curved edges one towards the other, on the side of their face opposite to the interior space. Thus, the curved edges are engaged between the lateral bearing surfaces and the deformable, deformed tongues. Also, the curved edges are then trapped in the connecting end, because their vertical movement is then prohibited, and the rim can not be engaged over the lug, as will be explained in detail below. Therefore, the two edges bent towards each other are trapped lateral support surfaces and the U-profile is then locked on the connecting end.
Au surplus, et de manière avantageuse, lesdites portées d'appui latérales s'étendent de entre une partie proximale et une partie distale, et ledit ergot est avantageusement situé dans la partie distale, de telle sorte que, lors du montage et de l'engagement de l'extrémité de liaison dans l'espace intérieur du profilé en U, les ergots viennent s'ajuster respectivement en arrière des rebords des bordures recourbées, tandis que précisément, ces rebords viennent s'étendre dans la partie proximale des portées d'appui latérales. On expliquera plus en détail dans la description détaillée le mode de coopération des ergots et des rebords.In addition, and advantageously, said lateral bearing surfaces extend from between a proximal portion and a distal portion, and said lug is advantageously located in the distal portion, so that during assembly and engagement of the connecting end in the inner space of the U-shaped profile, the lugs are respectively fitted behind the edges of curved edges, while precisely, these flanges are extended in the proximal portion of the spans of lateral support. The method of cooperation of the lugs and flanges will be explained in more detail in the detailed description.
Selon une variante d'exécution de l'invention, lesdites portées d'appui latérales opposées définissent une droite moyenne, et lesdites languettes déformables sont aptes à être entraînées en pivotement autour d'un axe sensiblement parallèle à ladite droite moyenne définie par lesdites portées d'appui. De la sorte, les languettes déformables peuvent être rabattues aisément contre les bordures recourbées et venir s'appliquer selon une direction sensiblement perpendiculaire, ce qui permet un meilleur verrouillage. Préférentiellement, et selon la variante d'exécution précitée, lesdites languettes présentent respectivement une zone de pivotement qui s'étend en regard desdites portées d'appui latérales et une extrémité libre opposée à ladite zone de pivotement, ainsi lorsque les languettes sont rabattues contre les bordures recourbées, la force de réaction des bordures recourbées contre les extrémités libres opposées, présente une direction coupant sensiblement la zone de pivotement ce qui améliore plus encore la sécurité du verrouillage.According to an alternative embodiment of the invention, said opposite lateral bearing surfaces define an average line, and said deformable tongues are adapted to be pivotally driven about an axis substantially parallel to said mean line defined by said staves. 'support. In this way, the deformable tongues can be easily folded against the curved edges and come to apply in a substantially perpendicular direction, which allows a better locking. Preferably, and according to the aforementioned alternative embodiment, said tongues respectively have a pivoting zone which extends opposite said lateral bearing surfaces and a free end opposite to said pivoting zone, thus when the tongues are folded against the curved edges, the reaction force of the curved edges against the opposite free ends, has a direction substantially intersecting the pivot area which further improves the security lock.
Selon une caractéristique particulièrement avantageuse, ladite extrémité libre de languette présente une portion latérale en oblique située au droit dudit ergot. De la sorte, lorsque les languettes déformables sont dans leur position écartée de la portée d'appui, l'espace libre entre les ergots et les languettes respectives est alors suffisamment important pour pouvoir engager sans peine les bordures recourbées entre languette et portée d'appui.According to a particularly advantageous characteristic, said tongue free end has an oblique lateral portion located at the right of said lug. In this way, when the deformable tongues are in their position away from the bearing surface, the free space between the lugs and the respective tongues is then large enough to be able to easily engage the curved edges between tongue and bearing surface .
Ladite extrémité de liaison définissant un plan moyen, lesdites languettes sont avantageusement inclinées, à l'opposé de ladite tige, en formant un angle aigu avec ledit plan moyen, lorsque ladite languette s'étend dans ladite position écartée. Et ainsi, la déformation des languettes déformables autour de leur zone de pivotement est d'une faible amplitude, inférieur à 90°, ce qui permet d'éviter la fragilisation locale du matériau, avantageusement de l'acier galvanisé, et ainsi de conserver son intégrité. Préférentiellement, les languettes sont inclinées d'un angle voisin de 45° avec ledit plan moyen.Said connecting end defining a mean plane, said tabs are advantageously inclined, opposite said rod, forming an acute angle with said middle plane, when said tab extends in said spaced position. And so, the deformation of the deformable tongues around their pivoting area is of a small amplitude, less than 90 °, which avoids the local embrittlement of the material, preferably galvanized steel, and thus to maintain its integrity. Preferably, the tongues are inclined at an angle close to 45 ° with said average plane.
Par ailleurs, ladite tige présente au moins un trou oblong s'étendant vers ladite extrémité de liaison, permettant de prérégler plus aisément la position verticale de la suspente.Furthermore, said rod has at least one oblong hole extending towards said connecting end, making it easier to preset the vertical position of the hanger.
En outre, dans le but de renforcer la rigidité de la tige de la suspente, ladite tige présente avantageusement deux rives latérales opposées, recourbées dans des sens opposés l'un de l'autre. Au surplus, la suspente de plafond est formée d'une seule pièce obtenue par découpage emboutissage, par exemple dans une plaque d'acier galvanisé.In addition, in order to reinforce the stiffness of the rod of the hanger, said rod advantageously has two opposite lateral edges curved in opposite directions from each other. In addition, the ceiling hanger is formed of a single piece obtained by cutting stamping, for example in a galvanized steel plate.

Aussi, dans cette situation, les bordures recourbées 40, 42 sont respectivement engagées à travers les entailles des bordures latérales opposées 18, 20 de l'extrémité de liaison 14 et précisément, en appui contre les portées d'appui opposé 22, 24. Au surplus, les ergots 30 sont engagés en arrière des bords libres repliés 44, 46, et ainsi respectivement en regard, latéralement, des deux épaulements opposés 48, 50. Ainsi, les bords libres repliés 44, 46 s'étendent respectivement dans la partie proximale 26 des portées d'appui latérales 22, 24. De la sorte, lorsqu'une force verticale F s'exerce sur le profilé en U 32, dans une direction opposée à l'extrémité de liaison 14, il tend à se déformer, mais les deux épaulements opposés 48, 50 des bords libres repliés 44, 46 viennent en butée latérale contre les ergots 30 ce qui interdit l'écartement des deux ailes en regard 36, 38 du profilé en U 32. De la sorte, malgré la déformation, le profilé en U 32 demeure en prise dans l'extrémité de liaison 14 de la suspente 10.Also, in this situation, the
