Description

Cette invention concerne une fixation pour profilés de plafonds suspendus et plus spécialement un type de fixation entre l'extrémité d'un profilé et l'âme, pourvue de fentes, d'un autre profilé.This invention relates to a fixing for profiles of suspended ceilings and more particularly to a type of fixing between the end of a profile and the core, provided with slots, of another profile.

L'invention concerne plus particulièrement une fixation pour profilés en acier galvanisé destinés à constituer la grille de fauxplafonds monolithiques.The invention relates more particularly to a fixing for galvanized steel profiles intended to constitute the grid of monolithic false ceilings.

On connaît plusieurs systèmes de fixation pour profilés de plafonds suspendus. Une première construction bien connue consiste à accrocher simplement et sans bloquage les profilés entre eux. Ce système présente l'inconvénient que les profilés se décrochent lorsqu'on les pousse vers le haut. Dans ce cas il est impossible de prévoir des constructions spéciales, telles que des trappes ou dispositifs semblables, sur lesquelles il faut pousser vers le haut, par exemple pour ouvrir et/ou fermer une trappe.Several fixing systems are known for suspended ceiling profiles. A first well-known construction consists in simply hanging the sections together without blocking them. This system has the disadvantage that the profiles come loose when pushed upwards. In this case it is impossible to provide special constructions, such as hatches or similar devices, on which it is necessary to push upwards, for example to open and / or close a hatch.

On connaît également un système où les profilés s'encastrent au moyen de lèvres, qu'il faut plier, afin de former un accrochage fixe. Il est manifeste qu'un tel assemblage demande du doigté et beaucoup de temps.There is also known a system where the profiles fit together by means of lips, which must be folded, in order to form a fixed attachment. It is obvious that such an assembly requires skill and a lot of time.

On troisième système emploie des pièces d'assemblage reliant les profilés entre eux, ce qui complique la constructionThe third system employs assembly parts connecting the profiles together, which complicates construction

On connait également, du document AU-B-472 037) une fixation pour profilés de plafonds suspendus avec un premier profilé s'emboîtant au moyen d'une saillie avec crochet dans une des fentes dont est pourvue l'âme du second profilé. La saillie se trouve au bout du premier profilé et forme un prolongement d'une partie de l'âme de ce profile de façon à ce que la saillie se trouve essentiellement dans le même plan que cette âme.Also known, from document AU-B-472 037) a fixing for suspended ceiling profiles with a first profile fitting by means of a projection with hook in one of the slots which is provided with the core of the second profile. The projection is at the end of the first profile and forms an extension of part of the core of this profile so that the projection is essentially in the same plane as this core.

Tous les systèmes présentent l'inconvénient de ne laisser nulle part assez de jeu pour la dilatation et/ou un assemblage souple des profilés.All systems have the drawback of not leaving enough clearance anywhere for expansion and / or flexible assembly of the profiles.

La présente invention prévoit, dans le but d'éliminer les inconvénients cités ainsi que d'autres, un assemblage de profilés pour plafonds suspendus, pouvant être réalisé simplement et rapidement, permettant la dilatation des profilés et ayant une fixation qui ne peut plus être démontée sans outilsThe present invention provides, in order to eliminate the aforementioned drawbacks as well as others, an assembly of profiles for suspended ceilings, which can be carried out simply and quickly, allowing the expansion of the profiles and having a fixing which can no longer be dismantled. without tools

A cette fin, la fixation selon l'invention se compose d'un bout de fixation d'au moins un premier profilé s'emboîtant au moyen d'une saillie, avec crochet à la forme d'un ardillon, dans une des fentes dont est pourvue l'âme du second profilé, dans laquelle ladite saillie se trouve au bout du premier profilé et forme un prolongement d'une partie de l'âme de ce profilé de façon à ce que la saillie se trouve essentiellement dans le même plan que cette âme, caractérisé en ce que au moins une des distances entre, d'une part, l'extrémité libre du crochet et, d'autre part, respectivement, les extrémités jouxtant la partie prolongée du premier profilé, soit plus grande que les distances horizontales correspondantes entre la surface de l'âme verticale du second profilé situées vers le crochet et les parties extrêmes de la section droite du second profilé situées vers le premier profilé, de façon à laisser du jeu entre une des parties nommées en dernier lieu et le second profilé.To this end, the fixing according to the invention consists of a fixing end of at least a first profile which fits by means of a projection, with a hook in the shape of a barb, in one of the slots, is provided with the core of the second profile, in which said projection is located at the end of the first profile and forms an extension of part of the core of this profile so that the projection is essentially in the same plane as this core, characterized in that at least one of the distances between, on the one hand, the free end of the hook and, on the other hand, respectively, the ends adjoining the extended part of the first profile, is greater than the distances corresponding horizontal lines between the surface of the vertical core of the second profile located towards the hook and the end portions of the cross section of the second profile located towards the first profile, so as to leave play between one of the last named parts and the second profile.

Dans le but de mieux démontrer les caractéristiques de l'invention, suvent, à titre d'exemple et sans aucune intention limitative, deux descriptions de réalisations préférables avec des renvois aux dessins annexées, dans lesquels:

  • la figure 1 est un croquis représentant une fixation selon l'invention;
  • la figure 2 montre, à plus grande échelle, un bout de fixation d'un profilé selon la figure 1;
  • les figures 3, 4 et 5 représentent le bout de fixation vu selon les flèches F3, F4 et F5;
  • la figure 6 représente une variante de l'exécution de la figure 2.
In order to better demonstrate the characteristics of the invention, there follow, by way of example and without any limiting intention, two descriptions of preferable embodiments with references to the appended drawings, in which:
  • Figure 1 is a sketch showing a binding according to the invention;
  • Figure 2 shows, on a larger scale, a fixing end of a profile according to Figure 1;
  • Figures 3, 4 and 5 show the fixing end seen according to arrows F3, F4 and F5;
  • FIG. 6 represents a variant of the execution of FIG. 2.

Se référant aux figures 1 à 5, la fixation se compose essentiellement d'un bout de fixation 1 d'au moins un profilé 2, qui peut s'emboîter à l'aide d'une saillie 3 d'un crochet 4 dans une fente 5 d'un second profilé 6.Referring to Figures 1 to 5, the fixing essentially consists of a fixing end 1 of at least one profile 2, which can be fitted using a projection 3 of a hook 4 in a slot 5 of a second profile 6.

La saillie 3 forme le prolongement d'une partie 7 de l'âme 8, ou éventuellement d'un bourrelet du premier profilé 2 et se trouve donc essentiellement dans le même plan.The projection 3 forms the extension of a part 7 of the core 8, or possibly of a bead of the first profile 2 and is therefore essentially in the same plane.

Le crochet 4 sur la saillie 3 est un ardillon formé, par exemple, par découpage au poinçonnage. Au moins une des distances, respectivement A et B, entre, d'une part, l'extrémité libre 9 du crochet 4 et, d'autre part, respectivement, les extrémités des parties 10 - 11 jouxtant la partie prolongée de l'âme, doit être plus grande que les distances, respectivement C et D, nécessaires pour mettre le second profilé 6 en place. Par conséquent existe un jeu 12 et/ou 13 entre au moins une des deux parties 10 - 11 et le profilé 6. Dans l'exemple donné il y a deux fois du jeu (12 et 13).The hook 4 on the projection 3 is a barb formed, for example, by punching cutting. At least one of the distances, respectively A and B, between, on the one hand, the free end 9 of the hook 4 and, on the other hand, respectively, the ends of the parts 10 - 11 adjoining the extended part of the core , must be greater than the distances, respectively C and D, necessary to put the second profile 6 in place. Consequently there is a clearance 12 and / or 13 between at least one of the two parts 10 - 11 and the profile 6. In the example given there are two clearances (12 and 13).

Dans le cas où il n'y a qu'une fois du jeu, ce qui a pour effet que le profilé ne peut plus se dilater, il vaut mieux garder du jeu en dessous, pour quand même permettre un assemblage souple des profilés 2 et 6.In the case where there is only one clearance, which has the effect that the profile can no longer expand, it is better to keep the clearance below, to still allow a flexible assembly of the profiles 2 and 6.

La saillie 3 peut être pourvue facultativement d'un emboutissage 14. Un tel emboutissage raidit la partie 3 et serre davantage les profilés 6 dans les fentes 5The projection 3 can optionally be provided with a stamping 14. Such a stamping stiffens the part 3 and further clamps the profiles 6 in the slots 5

Selon les figures 2 à 6, cet emboutissage peut ou ne peut pas se prolonger jusqu'au bout 15 de la saillie 3. La figure 6 représente une exécution alternative où le bout 15 est rectiligne.According to Figures 2 to 6, this stamping may or may not extend to the end 15 of the projection 3. Figure 6 shows an alternative embodiment where the tip 15 is straight.

L'invention permet également de monter deux profilés, chacun étant pourvu de bouts de fixation 1, de part et d'autre du second profilé au travers d'une seule et même fente 5, de façon à ce que ces profilés soient alignés sur un même axe.The invention also makes it possible to mount two profiles, each one being provided with fixing ends 1, on either side of the second profile through a single slot 5, so that these profiles are aligned on a same axis.

Le crochet 4 peut facultativement être pourvu d'une échancrure 16, qui facilite l'emboîtement du crochet 4 dans la fente 5.The hook 4 can optionally be provided with a notch 16, which facilitates the fitting of the hook 4 into the slot 5.
