U-shaped parts are connected to each other by inserting protrusions into slots so that U-shaped parts can be rotated around axis joining two flared protrusions. Self-drilling screw (34) is used to secure both U-shaped parts together. An independent claim is also included for a manufacturing process of a carrier structure, such as suspended ceiling.

Description

L'invention a pour objet un faux plafond avec une suspente, une partie en Forme de U pour une suspente et un procédé de fabrication d'un tel faux plafondThe invention relates to a false ceiling with a hanger, a U-shaped portion for a hanger and a method of manufacturing such a false ceiling

US-A-3 295 806 montre une partie en forme de U, selon le préambule de la revendication 5. US-A-3,295,806 shows a U-shaped portion, according to the preamble of claim 5.

FR-A-2 581 407 montre un faux plafond avec une suspente et un profilé. FR-A-2,581,407 shows a false ceiling with a hanger and a profile.

On connaît des suspentes fractionnées en plusieurs parties assemblées. Ces parties peuvent être positionnées et orientées les unes par rapport aux autres de sorte à permettre la réalisation d'une structure de niveau, même si le solivage ou, plus généralement, la structure de soutien ne l'est pas. Une partie supérieure de la suspente est fixée à la structure de soutien via une tige filetée, le cas échéant. La forme spécifique de la partie inférieure permet d'assembler cette partie inférieure avec un rail ou un profilé. Des rails ou profilés forment alors avec les suspentes une structure porteuse sur laquelle sont ultérieurement fixées des plaques pour réaliser un faux plafond.Frames are known to be divided into several assembled parts. These parts can be positioned and oriented relative to each other so as to allow the realization of a level structure, even if the joist or, more generally, the support structure is not. An upper portion of the hanger is attached to the support structure via a threaded rod, if any. The specific shape of the lower part makes it possible to assemble this lower part with a rail or a profile. Rails or profiles then form with the lines a supporting structure on which are subsequently fixed plates to achieve a false ceiling.

Or, de telles suspentes présentent des inconvénients.However, such lines have disadvantages.

Le maintien des parties de suspentes dans une orientation relative donnée, en vue de leur assemblage avec un profilé, nécessite parfois des éléments de fixation rapportés tels que des papillons ou des boulons.Maintaining the suspension parts in a given relative orientation, for assembly with a profile, sometimes requires attached fasteners such as butterflies or bolts.

En outre, la manipulation simultanée de ces parties et des éléments de fixation est peu pratique, compte-tenu des hauteurs typiques auxquelles les suspentes sont manipulées.In addition, the simultaneous manipulation of these parts and fasteners is impractical given the typical heights at which the lines are manipulated.

Par ailleurs, les parties de suspentes ne sont pas interchangeables.In addition, the parts of lines are not interchangeable.

De plus, la production des parties de suspente est encore compliquée du fait de leur dissemblance.In addition, the production of the suspension parts is further complicated because of their dissimilarity.

L'invention permet de résoudre les problèmes évoqués ci-dessus.The invention solves the problems mentioned above.

L'invention a pour objet un faux plafond, selon la revendication 1, avec une suspente comprenant deux parties en forme de U et comprenant chacune deux ailes sensiblement parallèles, dans laquelle :

  • une partie comprend un trou sur chacune de ses ailes
  • l'autre partie comprend une saillie sur chacune de ses ailes, en butée contre un bord de l'un des trous ; et
  • les parties sont montées à rotation l'une par rapport à l'autre et autour d'un axe rejoignant les saillies.
The invention relates to a false ceiling, according to claim 1, with a hanger comprising two U-shaped parts and each comprising two substantially parallel wings, in which:
  • a part includes a hole on each of its wings
  • the other part comprises a projection on each of its wings, abutting against an edge of one of the holes; and
  • the parts are rotatably mounted relative to each other and about an axis joining the projections.

Dans des modes de réalisation préférés, l'invention comprend une ou plusieurs des caractéristiques suivantes :

  • les saillies sont des collets battus et les trous sont des boutonnières ;
  • une partie en forme de U comprend en outre au moins un trou de serrage traversé par une vis fixant l'autre partie ;
  • les parties en forme de U sont identiques.
In preferred embodiments, the invention comprises one or more of the following features:
  • the projections are beaten collars and the holes are buttonholes;
  • a U-shaped portion further comprises at least one clamping hole traversed by a screw securing the other part;
  • the U-shaped parts are identical.

L'invention concerne également une partie en forme de U, selon la revendication 5, comprenant deux ailes sensiblement parallèles, avec sur chacune des ailes un trou et une saillie, les trous étant en regard et les saillies étant en regard.The invention also relates to a U-shaped portion, according to claim 5, comprising two substantially parallel wings, with on each of the wings a hole and a projection, the holes being opposite and the projections being opposite.

Selon une variante, chacune des saillies est un collet battu en saillie vers l'extérieur et chacun des trous est une boutonnière.According to a variant, each of the projections is a flanged collar protruding outwards and each of the holes is a buttonhole.

L'invention concerne également un procédé de fabrication d'un faux plafond, selon la revendication 7 , le procédé comprenant les étapes : de fourniture des parties en forme de U et d'un profilé ; de mise en place du profilé avec l'une des parties; d'assemblage des deux parties et d'ajustement d'un angle entre les deux parties par rotation ; de fixation des deux parties et de fixation, le cas échéant, du profilé avec l'une des parties.The invention also relates to a method of manufacturing a false ceiling, according to claim 7, the method comprising the steps of: providing the U-shaped portions and a profile; placing the profile with one of the parties; assembling the two parts and adjusting an angle between the two parts by rotation; fixing the two parts and fixing, if necessary, the profile with one of the parties.

Selon une variante, ce procédé comprend en outre une étape intermédiaire : de fourniture d'un moyen de fixation et d'assemblage de l'autre des parties avec ce moyen de fixation.According to a variant, this method also comprises an intermediate step: providing a fastening means and assembling the other parts with this fixing means.

D'autres caractéristiques et avantages de l'invention apparaîtront à la lecture de la description qui suit de modes de réalisation préférés de l'invention, donnée à titre d'exemple et en référence aux dessins annexés montrant :

  • Figure 1 : une structure porteuse avec : une suspente, selon l'invention, comprenant deux parties en forme de U ; et un profilé mis en place dans la suspente.
  • Figure 2 : une partie en forme de U d'une suspente selon l'invention ;
  • Figure 3 : une vue de profil d'une partie en forme de U d'une suspente selon l'invention ;
Other characteristics and advantages of the invention will appear on reading the following description of preferred embodiments of the invention, given by way of example and with reference to the appended drawings showing:
  • Figure 1: a support structure with: a hanger, according to the invention, comprising two U-shaped parts; and a profile put in place in the hanger.
  • Figure 2: a U-shaped portion of a hanger according to the invention;
  • Figure 3 is a side view of a U-shaped portion of a hanger according to the invention;

Ainsi; l'invention propose-t-elle une suspente qui, une fois assemblée, comprend deux parties en forme de U comprenant chacune deux ailes sensiblement parallèles, dans laquelle : une partie comprend un trou sur chacune de ses ailes ; l'autre partie comprend une saillie sur chacune de ses ailes, en butée contre un bord de l'un des trous ; et les parties sont montées à rotation l'une par rapport à l'autre et autour d'un axe rejoignant les saillies.So; the invention proposes a hanger which, once assembled, comprises two U-shaped parts each comprising two substantially parallel wings, wherein: a portion comprises a hole on each of its wings; the other part comprises a projection on each of its wings, abutting against an edge of one of the holes; and the parts are rotatably mounted relative to each other and about an axis joining the projections.

La suspente est assemblée en insérant les saillies dans les trous. Une traction exercée sur chacune des parties assemblées, en sens opposé, permet aux saillies de venir en butée sur un bord des trous. Les deux parties peuvent donc être pivotée l'une par rapport à l'autre et autour d'un axe rejoignant les saillies.The hanger is assembled by inserting the projections into the holes. Traction on each of the assembled parts in opposite directions allows the projections to abut on one edge of the holes. The two parts can therefore be rotated relative to each other and around an axis joining the projections.

Il n'est donc pas nécessaire d'utiliser ni de manipuler des éléments de fixation rapportés tels que des papillons ou des boulons. De plus, la production des deux parties de la suspente est facilitée du fait de la ressemblance de ces parties. Ces parties sont en outre interchangeables, par leur conception, c'est-à-dire que la suspente peut être assemblée avec à un moyen de fixation tel qu'une tige filetée via l'une quelconque de ces parties.It is therefore not necessary to use or manipulate reported fasteners such as butterflies or bolts. In addition, the production of both parts of the hanger is facilitated because of the similarity of these parts. These parts are further interchangeable, by design, that is to say that the hanger can be assembled with a fastening means such as a threaded rod via any of these parts.

La figure 1 montre une structure porteuse 33 avec : une suspente 10, selon l'invention, comprenant deux parties en forme de U 11,21 ; et un profilé 31 mis en place dans la suspente 10. Chaque partie 11,21 comprend deux ailes 12,13,22,23 sensiblement parallèles. Par « sensiblement parallèles », on entend que les ailes ne sont, de préférence, pas écartées d'un angle supérieur à 10° du plan moyen des deux ailes dans leur position d'équilibre. La base 20,30 reliant les deux ailes d'une même partie peut être de forme quelconque, par exemple, de forme cylindrique ou alors plate, comme dans l'exemple de la figure 1. Une partie 21 comprend un trou 24,25 sur chacune de ses ailes et l'autre partie 11 comprend une saillie 16,17 sur chacune de ses ailes 12,13, en butée contre un bord de l'un des trous 24,25. Les figures 1, 2 et 3 montrent des saillies orientées vers l'extérieur de leur partie respective mais une telle orientation n'est pas obligatoire pour l'invention. Les parties en U 11 et 21 sont montées à rotation l'une par rapport à l'autre et autour d'un axe rejoignant les saillies 16 et 17. Chacune des parties peut, par exemple, être en acier galvanisé ou en un matériau présentant une certaine élasticité et capable de supporter la masse d'un plafond multipliée par un coefficient de sécurité.Figure 1 shows a supporting structure 33 with: a hanger 10, according to the invention, comprising two U-shaped portions 11,21; and a profile 31 placed in the hanger 10. Each portion 11,21 comprises two wings 12,13,22,23 substantially parallel. By "substantially parallel" is meant that the wings are preferably not separated by an angle greater than 10 ° from the mean plane of the two wings in their equilibrium position. The base 20,30 connecting the two wings of the same part may be of any shape, for example of cylindrical or flat shape, as in the example of Figure 1. A portion 21 comprises a hole 24.25 on each of its wings and the other portion 11 comprises a projection 16,17 on each of its wings 12,13, abutting against an edge of one of the holes 24,25. Figures 1, 2 and 3 show outwardly directed projections of their respective portion but such an orientation is not mandatory for the invention. The U-shaped portions 11 and 21 are rotatably mounted relative to one another and about an axis joining the projections 16 and 17. Each of the parts may, for example, be of galvanized steel or a material having a certain elasticity and capable of supporting the mass of a ceiling multiplied by a factor of safety.

La suspente 10 est assemblée en pressant légèrement les deux ailes 12,13 de la partie 11 comprenant les saillies 16,17, puis en insérant cette partie dans l'autre partie 21. La pression est relâchée lorsque l'axe des saillies 16,17 se retrouve aligné avec celui des trous 24,25, c'est-à-dire lorsque les saillies sont en face des trous. Les ailes de la partie comprenant les saillies sont rappelées vers leur position d'équilibre, viennent en contact avec la surface interne des ailes de l'autre partie et les saillies traversent les trous de l'autre partie. Une traction exercée sur chacune des parties assemblées, en sens opposé, permet alors aux saillies de venir en butée sur un bord des trous. Les deux parties peuvent donc être pivotée l'une par rapport à l'autre et autour d'un axe rejoignant les saillies.The hanger 10 is assembled by lightly pressing the two wings 12,13 of the part 11 comprising the projections 16,17, then inserting this part into the other part 21. The pressure is released when the axis of the projections 16,17 is aligned with that of the holes 24,25, that is to say when the projections are in front of the holes. The wings of the portion comprising the projections are returned to their equilibrium position, come into contact with the inner surface of the wings of the other party and the projections pass through the holes of the other party. Traction exerted on each of the assembled parts, in opposite directions, then allows the projections to abut on an edge of the holes. The two parts can therefore be rotated relative to each other and around an axis joining the projections.

La pression due à la force de rappel des ailes élastiquement déformées d'une partie contre les deux autres ailes est suffisante pour permettre une immobilisation temporaire des deux parties en forme de U. Il n'est donc pas nécessaire d'utiliser ni de manipuler des éléments de fixation rapportés tels que des papillons ou des boulons. De plus, la production des deux parties de la suspente est facilitée du fait du nombre restreint et de la ressemblance de ces parties. En outre, le contact entre les saillies et les bords des trous permet aux parties d'être interchangeables, c'est-à-dire que chacune des deux parties peut être fixée via sa base à une tige filetée ou tout autre moyen de fixation adapté.The pressure due to the restoring force of the elastically deformed wings of one part against the other two wings is sufficient to allow a temporary immobilization of the two U-shaped parts. It is therefore not necessary to use or manipulate reported fasteners such as butterflies or bolts. In addition, the production of both parts of the hanger is facilitated because of the limited number and similarity of these parts. In addition, the contact between the projections and the edges of the holes allows the parts to be interchangeable, that is to say that each of the two parts can be fixed via its base to a threaded rod or any other suitable fastening means .

Comme dans l'exemple de la figure 1, les saillies 16,17 peuvent être des collets battus, c'est-à-dire qu'une saillie 16 peut former un tube à l'extérieur d'une aile 12, dont le bord est relevé. Il convient de noter qu'une saillie 16 peut également former un tube à l'intérieur d'une aile 12 et que dans ce cas, l'assemblage des parties 11,21 peut être fait par pressage des ailes 22,23 d'une partie 21, puis en insérant cette partie 21 dans l'autre partie 11, de façon similaire à ce qui a été décrit plus haut. Le relevage du bord d'un collet sécurise la rotation des deux parties un fois le collet d'une partie en butée contre un bord d'un trou de l'autre partie, comme il sera expliqué en référence à la figure 3. Un collet battu peut être obtenu par emboutissage d'une aile. Ainsi, les saillies peuvent être obtenues en une étape de production.As in the example of Figure 1, the projections 16,17 may be beaten collars, that is to say, a projection 16 may form a tube on the outside of a wing 12, the edge is raised. It should be noted that a projection 16 can also form a tube inside a wing 12 and that in this case, the assembly of the parts 11,21 can be done by pressing the wings 22,23 of a part 21, then inserting this part 21 in the other part 11, similar to what has been described above. The lifting of the edge of a collar secures the rotation of the two parts once the neck of one part abuts against an edge of a hole of the other part, as will be explained with reference to Figure 3. A collar beaten can be obtained by stamping a wing. Thus, the projections can be obtained in one production step.

A l'instar de l'exemple montré sur la figure 1, les trous 24,25 peuvent être des boutonnières, c'est-à-dire des trous plus grand à une extrémité (ci-après : l'entrée de la boutonnière) qu'à l'autre extrémité (ci-après : la rainure de la boutonnière). Une autre façon de décrire la boutonnière est de la comparer au résultat de la superposition partielle d'alésages de diamètres différents.As in the example shown in FIG. 1, the holes 24, 25 may be buttonholes, that is to say larger holes at one end (hereinafter: the entrance to the buttonhole) at the other end (hereinafter: the buttonhole groove). Another way of describing the buttonhole is to compare it to the result of the partial superposition of bores of different diameters.

Les boutonnières permettent une insertion aisée des saillies (par exemple des collets battus) à travers l'entrée de la boutonnière tandis que le diamètre de la rainure est ajusté sur le diamètre extérieur du tube formé par le collet battu. La forme de la boutonnière peut être affinée de sorte à optimiser le maintien du collet battu dans la rainure. Par exemple, il peut être avantageux de prévoir un crénelage sur les bords des trous. Il peut encore être avantageux d'excentrer suffisamment les alésages partiellement superposés afin de former deux rebords à leurs intersections. De tels rebords, élastiquement déformables, permettent d'encliqueter le collet en translation dans la rainure. Le collet peut cependant être désengagé de la rainure en effectuant une traction suffisante sur chacune des deux parties.The buttonholes allow easy insertion of protrusions (eg, flanged collars) through the entrance of the buttonhole while the diameter of the groove is adjusted to the outer diameter of the tube formed by the flanged collar. The shape of the buttonhole can be refined to optimize the maintenance of the flanged collar in the groove. For example, it may be advantageous to provide a crenellation on the edges of the holes. It may further be advantageous to sufficiently offset the partially overlapped bores to form two flanges at their intersections. Such flanges, elastically deformable, allow to snap the collar in translation in the groove. The collar may however be disengaged from the groove by providing sufficient traction on each of the two parts.

Toujours en référence à la figure 1, une partie 11, 21 en forme de U peut en outre comprendre un ou plusieurs trous 18,19,28,29 de serrage.Still with reference to FIG. 1, a U-shaped portion 11, 21 may further comprise one or more clamping holes 18, 19, 28, 29.

En particulier, une pluralité de trous de serrage situés à l'extrémité libre d'une première aile d'une partie permet d'assurer la présence d'un trou au voisinage du milieu de l'aile de l'autre partie en contact avec la première aile, quelle que soit l'orientation mutuelle des deux parties en forme de U. Une vis auto-foreuse 34 ou tout autre moyen de fixation adapté traversant l'un des trous permet alors de fixer les deux parties en vue de leur assemblage définitif. D'autres trous 18,19,28,29 disposés plus à l'intérieur des ailes peuvent en outre permettre la fixation d'une partie 11,21 avec un profilé 31 au moyen d'une vis auto-foreuse 36. En outre, prévoir un trou sur la base 20,30 d'une partie en forme de U peut également être utile à la fixation d'une partie 11,21 avec un moyen de fixation tel qu'une tige filetée 32. Ainsi, il est possible de procéder, pour la fabrication d'une structure porteuse, à :

  • la fixation d'une partie 11 avec un moyen de fixation tel qu'une tige filetée 32 ;
  • la mise en place d'un profilé 31 avec l'autre partie 21;
  • l'assemblage des deux parties 11,21 et à l'ajustement d'un angle entre les deux parties 11,21 par rotation ;
  • la fixation des deux parties 11,21 et, le cas échéant, à la fixation du profilé 31 avec l'autre partie 21. Bien entendu, il est possible de procéder de façon similaire pour la fabrication d'une structure porteuse comprenant plusieurs suspentes.
In particular, a plurality of clamping holes located at the free end of a first wing of a portion makes it possible to ensure the presence of a hole in the vicinity of the middle of the wing of the other part in contact with the the first wing, regardless of the mutual orientation of the two U-shaped portions. A self-drilling screw 34 or any other suitable fastening means passing through one of the holes then makes it possible to fix the two parts in view of their assembly. final. Other holes 18, 19, 28, 29 arranged further inside the wings may further allow the attachment of a portion 11, 21 with a profile 31 by means of a self-drilling screw 36. In addition, providing a hole on the base 20,30 of a U-shaped portion may also be useful for fixing a portion 11,21 with a fastening means such as a threaded rod 32. Thus, it is possible to proceed, for the manufacture of a supporting structure, to:
  • fixing a portion 11 with a fastening means such as a threaded rod 32;
  • the establishment of a profile 31 with the other part 21;
  • assembling the two parts 11,21 and adjusting an angle between the two parts 11,21 by rotation;
  • the attachment of the two parts 11,21 and, where appropriate, the attachment of the section 31 with the other part 21. Of course, it is possible to proceed in a similar manner for the manufacture of a carrier structure comprising several lines.

Toujours en référence à la figure 1, il peut être avantageux de prévoir des parties 11,21 identiques. C'est-à-dire que la partie 11 peut en outre comprendre un trou 14,15, par exemple une boutonnière, sur chacune de ses ailes 12,13 et la partie 21 peut en outre comprendre une saillie 26,27, par exemple un collet battu, sur chacune de ses ailes 22,23.Still with reference to FIG. 1, it may be advantageous to provide identical parts 11, 21. That is to say, the portion 11 may further comprise a hole 14,15, for example a buttonhole, on each of its wings 12,13 and the portion 21 may further comprise a projection 26,27, for example a beaten collar, on each of its wings 22,23.

Ainsi, les parties en forme de U ne nécessitent qu'une seule ligne de production. La production, le conditionnement et le transport des parties en forme de U s'en trouvent facilités. En outre, l'opérateur effectuant la fabrication de la suspente avec un profilé n'a pas à se soucier du rôle de chacune des parties.Thus, the U-shaped parts require only one production line. The production, packaging and transport of the U-shaped parts are facilitated. In addition, the operator performing the manufacture of the hanger with a profile does not have to worry about the role of each party.

La figure 2 montre une partie 11 en forme de U d'une suspente 10 selon l'invention. Cette partie 11 comprend deux ailes sensiblement parallèles, avec sur chacune des ailes 12,13 un trou 14,15 et une saillie 16,17, les trous étant en regard et les saillies étant en regard.Figure 2 shows a U-shaped portion 11 of a hanger 10 according to the invention. This portion 11 comprises two substantially parallel wings, with on each of the wings 12,13 a hole 14,15 and a projection 16,17, the holes being opposite and the projections being opposite.

Une telle partie 11 peut être assemblée avec une autre partie 21, identique, afin d'obtenir une suspente 10 telle que décrit précédemment.Such a portion 11 can be assembled with another part 21, identical, to obtain a hanger 10 as described above.

En particulier, la figure 2 montre un exemple de partie 11 en forme de U, dans laquelle chacune des saillies 16,17 est un collet battu en saillie vers l'extérieur de la partie et chacun des trous 14,15 est une boutonnière, comme décrit précédemment.In particular, FIG. 2 shows an example of a U-shaped portion 11, in which each of the projections 16, 17 is a flanged collar projecting outwardly from the portion and each of the holes 14, 15 is a buttonhole, as previously described.

La figure 3 montre une vue de profil d'une telle partie 11 en forme de U. Dans cet exemple, la partie comprend une base de forme plate et sensiblement perpendiculaire aux deux ailes 12,13, comme décrit précédemment. Les collets battus 16,17 sont clairement visibles sur la figure. En particulier, il est possible de distinguer le relevage du bord des tubes formant la base des collets battus.FIG. 3 shows a profile view of such a U-shaped portion 11. In this example, the portion comprises a base of flat shape and substantially perpendicular to the two wings 12, 13, as previously described. The beaten collars 16,17 are clearly visible in the figure. In particular, it is possible to distinguish the lifting of the edge of the tubes forming the base of the beaten collars.

C'est entre le relevage du bord d'un tube et une aile que vient buter le bord d'un trou ou de la rainure d'une boutonnière d'une autre partie, ce qui permet de faciliter la rotation de deux parties lorsqu'elles sont assemblées comme dans l'exemple de la figure 1.It is between the lifting of the edge of a tube and a wing that abuts the edge of a hole or the groove of a buttonhole of another part, which facilitates the rotation of two parts when they are assembled as in the example of Figure 1.

L'invention n'est pas limitée aux modes de réalisation décrits mais est susceptible de nombreuses variations aisément accessibles à l'homme du métier dans l'étendue du jeu de revendications.The invention is not limited to the embodiments described but is capable of numerous variations easily accessible to those skilled in the art within the scope of the set of claims.
