Description

La présente invention concerne d'une manière générale l'accrochage d'un quelconque élément d'ossature à un quelconque support, et elle vise plus particulièrement, mais non nécessairement exclusivement, le cas où il s'agit de suspendre à une première ossature, ou ossature primaire, une autre ossature, ou ossature secondaire, propre à recevoir un plafond, avec, dans l'intervalle, un ou plusieurs doublages thermo-acoustiques.The present invention relates generally to the attachment of any frame element to any support, and it relates more particularly, but not necessarily exclusively, to the case where it is a question of hanging from a first frame, or primary framework, another framework, or secondary framework, suitable for receiving a ceiling, with, in the meantime, one or more thermo-acoustic linings.

Pour la suspension d'un tel plafond, il a été proposé, dans le brevet français qui, déposé le 16 Octobre 1979 sous le No 79 25655 a été publié sous le No 2.467.927, de mettre en oeuvre des suspentes comportant, à leur extrémité, une tête de fixation propre à permettre d'y assujettir les éléments d'ossature, en l'espèce des fourrures métalliques, sur lesquels il faut ensuite rapporter les plaques ou panneaux propres à constituer ce plafond.For the suspension of such a ceiling, it was proposed, in the French patent which, filed on October 16, 1979 under No. 79 25655 was published under No. 2,467,927, to implement lines comprising, at their end, a fixing head suitable for fixing the framework elements, in this case metal furs, on which it is then necessary to attach the plates or panels suitable for constituting this ceiling.

En pratique, dans ce brevet français, l'assujettissement d'un élément d ossature à une telle suspente se fait par simple encliquetage, cet élément d'ossature ayant globalement un profil transversal en U, par lequel il est propre à s'engager sur la tête de fixation de cette suspente, et dont les ailes présentent, en direction l'une de l'autre, à leur extrémité, des retours en équerre, et ladite tête de fixation présentant, latéralement, à un même niveau, pour réception de ces retours en équerre, deux encoches orientées dos à dos l'une par rapport à l'autre, avec, latéralement, un profil largement arrondi propre à guider ces retours en équerre en direction de ces encoches.In practice, in this French patent, the subjugation of a frame element to such a hanger is done by simple snap-fastening, this frame element generally having a transverse U-shaped profile, by which it is capable of engaging on the fixing head of this hanger, and the wings of which have, in the direction of one another, at their ends, angled returns, and the said fixing head having, laterally, at the same level, for reception of these square returns, two notches oriented back to back with respect to one another, with, laterally, a broadly rounded profile suitable for guiding these square returns towards these notches.

Cette disposition a donné et donne encore satisfaction.This arrangement has given and still gives satisfaction.

Elle se trouve cependant en défaut lorsqu'un doublage thermo-acoustique doit être prévu.It is however in default when a thermo-acoustic doubling must be planned.

Pour la suspension ou l'accrochage spécifique d'un tel doublage thermo-acoustique, il est connu, de longue date, notamment par les demandes de brevets allemands Nos 1.056.349 et 29 03 897, de mettre en oeuvre des suspentes ou autres organes d'accrochage, qui, par une extrémité en forme de pointe, sont propres à traverser directement les plaques ou panneaux en matériau isolant à poser, les matériaux usuellement mis en oeuvre pour la constitution de tels plaques ou panneaux ne présentant normalement à cet égard qu'une faible résistance à la pénétration, et dont l'extrémité en forme de pointe est à plier à l'équerre après cette traversée, pour la retenue de ces plaques ou panneaux.For the specific suspension or hanging of a such thermo-acoustic doubling, it has been known for a long time, in particular by German patent applications Nos 1,056,349 and 29 03 897, to use lines or other fastening members, which, by a shaped end tip, are suitable for passing directly through the plates or panels of insulating material to be laid, the materials usually used for the constitution of such plates or panels normally having in this respect only a low resistance to penetration, and whose l 'tip-shaped end is to be bent at right angles after this crossing, for the retention of these plates or panels.

En développement de cette disposition, il a été proposé, dans la demande de brevet français qui, déposée le 6 Janvier 1984 sous le No 84 00183, a été publiée sous le No 2.557.901, pour la suspension d un faux plafond, avec, au-dessus de lui, un ou plusieurs doublages thermo-acoustiques, d'associer à une suspente propre ainsi à traverser directement les plaques ou panneaux constitutifs d'un tel doublage thermo-acoustique, une pièce supplémentaire, en l'espèce un étrier, qui, reprenant le profil de la tête de fixation de la suspente précédente, est propre, lui, à l'accrochage des fourrures métalliques nécessaires au support des plaques ou panneaux constitutifs d'un tel faux plafond.In development of this provision, it was proposed in the French patent application which, filed on January 6, 1984 under No. 84 00183, was published under No. 2,557,901, for the suspension of a false ceiling, with, above it, one or more thermo-acoustic doublings, to associate with a clean hanger thus to pass directly through the plates or panels constituting such thermo-acoustic doubling, an additional part, in this case a stirrup, which, taking up the profile of the fixing head of the preceding hanger, is suitable for attaching the metallic furs necessary for supporting the plates or panels constituting such a false ceiling.

Bien qu'une telle disposition donne elle aussi satisfaction, elle implique, de manière dispendieuse, la mise en oeuvre de deux pièces distinctes, au détriment des coûts de fabrication, de stockage et de montage de l'ensemble.Although such an arrangement is also satisfactory, it involves, in an expensive manner, the implementation of two separate parts, to the detriment of the manufacturing, storage and assembly costs of the assembly.

Elle implique en outre de devoir normalement prévoir, également de manière dispendieuse, deux types de suspentes distinctes, les unes, avec étrier, à mettre en oeuvre lorsqu'un doublage thermo-acoustique est nécessaire, les autres, sans étrier, à mettre en oeuvre dans le cas contraire.It also implies having to normally provide, also costly, two distinct types of lines, some with a stirrup, to be used when a thermo-acoustic lining is necessary, others, without a stirrup, to be used otherwise.

Il a également été proposé, en développement de la suspente faisant l'objet du brevet français No 79 25655 mentionné ci-dessus, d'affiner en pointe cette suspente, pour qu'elle soit plus aisément en mesure de traverser un doublage thermo-acoustique, et de lui associer une pièce supplémentaire, en l'espèce une simple butée d'arrêt, qui, montée réglable en position, par encliquetage, le long de cette suspente, à la faveur des perçages prévus par ailleurs le long de celle-ci pour sa fixation, est propre à la retenue de ce doublage thermo-acoustique.It has also been proposed, in development of the line which is the subject of French patent No 79 25655 mentioned above, to refine this line at a point, so that it is more easily able to pass through a thermo-acoustic lining, and to associate it with an additional part, in this case a simple stop stop, which, mounted adjustable in position, by snap-fastening, along this hanger, thanks to the holes provided elsewhere along the latter for its fixing, is suitable for retaining this thermo-acoustic lining.

Mais outre que, comme précédemment, cette butée d'arrêt constitue, de manière dispendieuse, une pièce supplémentaire, elle nécessite d'être engagée, à force, par en dessous sur la suspente à équiper, au risque de se blesser la main contre celle-ci.But besides that, as before, this stop constitutes, in an expensive way, an additional part, it needs to be engaged, by force, from below on the hanger to be equipped, at the risk of injuring the hand against that -this.

La présente invention a d'une manière générale pour objet une disposition permettant avantageusement d'éviter ces inconvénients.The present invention generally relates to a provision advantageously making it possible to avoid these drawbacks.

De manière plus précise, elle a pour objet une suspente, qui, pour l'accrochage, d'une manière générale, d'un quelconque élément d'ossature à un quelconque support, est du genre comportant, à son extrémité, une tête de fixation propre à permettre d'y assujettir un tel élément d'ossature, cette suspente étant d'une manière générale caractérisée en ce que sa tête de fixation est encadrée par une pointe pliable à l'équerre.More specifically, it relates to a hanger, which, for the attachment, in general, of any frame element to any support, is of the type comprising, at its end, a head fixing suitable for making it possible to subject such a frame element to it, this hanger being generally characterized in that its fixing head is framed by a point that can be folded square.

Par exemple, cette pointe est formée par deux languettes, qui sont chacune individuellement pliables à l'équerre.For example, this point is formed by two tongues, which are each individually foldable at right angles.

En variante, elle est d un seul tenant.Alternatively, it is in one piece.

Quoi qu'il en soit, par la pointe qu'elle présente ainsi, et qui, initialement, est dans son propre alignement, la suspente suivant l'invention est apte à traverser directement les plaques ou panneaux à mettre en oeuvre pour la constitution d'un doublage thermo-acoustique lorsqu'un tel doublage thermo-acoustique est prévu.Anyway, by the point which it thus presents, and which, initially, is in its own alignment, the hanger according to the invention is able to pass directly through the plates or panels to be used for the constitution of 'a thermo-acoustic lining when such a thermo-acoustic lining is provided.

Il suffit, ensuite, pour la retenue de ce doublage thermo-acoustique, de plier à l'équerre cette pointe.Then, for the retention of this thermo-acoustic lining, it is sufficient to bend this point square.

Mais, ce faisant, et suivant l'invention, on dégage alors la tête de fixation propre, ensuite, au support des éléments d ossature à fixer.However, in doing so, and according to the invention, the clean fixing head is then released, then to the support of the frame elements to be fixed.

Ainsi, suivant l'invention, une seule et même pièce convient à la fois à la traversée d'un doublage thermo-acoustique et à la suspension d'un élément d'ossature.Thus, according to the invention, one and the same piece is suitable both for crossing a thermo-acoustic lining and for suspending a framework element.

Les coûts de fabrication et de stockage s'en trouvent avantageusement minimisés d'autant, et il en est de même pour les coûts de mise en oeuvre, cette mise en oeuvre se trouvant grandement facilitée.The manufacturing and storage costs are advantageously minimized accordingly, and the same is true for the implementation costs, this implementation being greatly facilitated.

Si désiré, la suspente suivant l'invention peut d'ailleurs tout aussi bien convenir au cas où aucun doublage thermo-acoustique n'est prévu.If desired, the hanger according to the invention can also be just as suitable in the event that no thermo-acoustic lining is provided.

Il suffit, en effet, de plier de toute façon à l'équerre sa pointe lorsque, comme cela est alors le cas, seule sa tête de fixation est à mettre en oeuvre.It suffices, in fact, to bend its point anyway at an angle when, as is then the case, only its fixing head is to be used.

Mais, par ailleurs, lorsque plusieurs doublages thermo-acoustiques successifs sont prévus, la suspente suivant l'invention peut également présenter, en position intermédiaire, en-deçà de sa tête de fixation, au moins une autre languette pliable à l'équerre et propre ainsi, suivant un processus analogue au précédent, à la retenue, dans l'intervalle, d'au moins un autre doublage thermo-acoustique supplémentaire.But, moreover, when several successive thermo-acoustic doublings are provided, the hanger according to the invention may also have, in the intermediate position, below its fixing head, at least one other foldable tab at right angles and clean thus, following a process analogous to the previous one, withholding, in the meantime, at least one other additional thermo-acoustic doubling.

En bref, la suspente suivant l'invention est avantageusement de nature à se prêter de manière quasi universelle à divers cas de mise en oeuvre différents.In short, the hanger according to the invention is advantageously likely to lend itself almost universally to various different cases of implementation.

Ces figures, et plus particulièrement les figures 3A, 3B, 3C illustrent, à titre d'exemple, le cas où il s'agit, globalement, de suspendre, à un quelconque plancher, un quelconque plafond.These figures, and more particularly Figures 3A, 3B, 3C illustrate, by way of example, the case where it is a question, overall, of suspending, from any floor, any ceiling.

Plus précisément, il s'agit, dans ce cas, d'accrocher, aux éléments d'ossature de support primaire que constituent les chevrons 10 porteurs d'un tel plancher, des éléments d'ossature secondaire 11 aptes à porter un tel plafond.More specifically, it is, in this case, to hang, to the primary support frame elements that constitute the rafters 10 carrying such a floor, secondary frame elements 11 able to carry such a ceiling.

De manière connue en soi, il est mis en oeuvre, pour ce faire, des suspentes 12 comportant, d une part, une partie courante 13, ou queue, par laquelle elles sont adaptées à être fixées aux chevrons 10, et, d'autre part, à l'extrémité de ladite partie courante 13, une tête de fixation 14, propre à permettre d'y assujettir les éléments d'ossature secondaire 11.In a manner known per se, lines 12 are used to do this, comprising, on the one hand, a main part 13, or tail, by which they are adapted to be fixed to the rafters 10, and, on the other hand, at the end of said main part 13, a fixing head 14, suitable for allowing the secondary framework elements 11.

Dans la forme de mise en oeuvre illustrée à titre d'exemple, les chevrons 10, qui, à un pas régulier, sont établis parallèlement les uns aux autres, sont en bois, et les éléments d'ossature secondaire 11, qui sont eux-mêmes établis, à un pas régulier, parallèlement les uns aux autres, en étant entrecroisés à 90° avec les chevrons 10, sont, par contre, des fourrures métalliques à profil transversal en U dont les ailes 15 présentent, le long de leurs bords libres, en direction l'une de l'autre, et parallèlement à la partie médiane 16 qu'elles encadrent, des retours en équerre 17.In the embodiment illustrated by way of example, the rafters 10, which, at a regular pitch, are established parallel to each other, are made of wood, and the secondary framework elements 11, which are themselves same established, at a regular pitch, parallel to each other, being crisscrossed at 90 ° with the rafters 10, are, on the other hand, metallic furs with a transverse U-shaped profile whose wings 15 have, along their free edges , in the direction of one another, and parallel to the middle part 16 which they frame, returns at right angles 17.

De telles fourrures métalliques étant bien connues par elles-mêmes, et ne faisant pas partie en soi de la présente invention, elles ne seront pas décrites plus en détail ici.As such metal furs are well known in themselves, and not being in themselves part of the present invention, they will not be described in more detail here.

De manière également connue en soi, la partie courante 13, ou queue, de la suspente 12 suivant l'invention comporte, établis à un pas régulier le long de son axe longitudinal médian, sur une partie au moins de sa longueur, des perçages 18, propres, chacun individuellement, au passage de moyens de fixation, tels que vis ou pointe, de nature à permettre l'assujettissement de l'ensemble à un chevron 10.In a manner also known per se, the running part 13, or tail, of the hanger 12 according to the invention comprises, established at a regular pitch along its median longitudinal axis, over at least part of its length, holes 18 , specific, each individually, to the passage of fastening means, such as screws or points, such as to allow the assembly of the assembly to a chevron 10.

Dans sa zone médiane 19, au moins, cette partie courante 13 est globalement plate.In its central area 19, at least, this main part 13 is generally flat.

Dans les formes de réalisation représentées, cette partie courante 13 est ainsi plate sur la totalité de la largeur de sa zone médiane 19.In the embodiments shown, this main part 13 is thus flat over the entire width of its central zone 19.

De préférence, cependant, et tel que représenté, elle présente, latéralement, le long de ses bords longitudinaux, et sur la totalité de sa hauteur, des raidisseurs 20 propres à la rigidifier et à lui permettre de reprendre sans déformation d'éventuels efforts transversaux.Preferably, however, and as shown, it has, laterally, along its longitudinal edges, and over its entire height, stiffeners 20 capable of stiffening it and allowing it to resume without deformation of any transverse forces.

Dans la forme de réalisation plus particulièrement représentée sur les figures 1 et 2, ces raidisseurs 20, qui sont disposés symétriquement par rapport à l'axe longitudinal médian suivant lequel s'alignent les perçages 18, et qui, en pratique, résultent d'un simple pliage, ont, transversalement, un profil en équerre, en étant constitués, d'une part, d'un rebord 21, qui s étend sensiblement perpendiculairement au plan de la zone médiane 19 de la partie courante 13 qu'ils affectent, et, d'autre part, d'un retour 22, qui, parallèle à cette zone médiane 19, s'étend vers l'extérieur perpendiculairement au rebord 21 précédent, le long du bord libre de celui-ci.In the embodiment more particularly shown in Figures 1 and 2, these stiffeners 20, which are arranged symmetrically with respect to the median longitudinal axis along which the holes 18 are aligned, and which, in practice, result from a simple folding, have, transversely, a square profile, being constituted, on the one hand, by a rim 21, which extends substantially perpendicular to the plane of the central zone 19 of the main part 13 which they affect, and , on the other hand, a return 22, which, parallel to this median zone 19, extends outwards perpendicularly to the preceding flange 21, along the free edge thereof.

Pour des raisons qui apparaîtront ultérieurement, les raidisseurs 20 ainsi constitués sont biaisés par un chanfrein 24 à celle de leurs extrémités qui est proche de la tête de fixation 14.For reasons which will appear later, the stiffeners 20 thus formed are biased by a chamfer 24 at that of their ends which is close to the fixing head 14.

S'agissant de la mise en oeuvre d'éléments d'ossature secondaire 11 présentant, comme indiqué ci-dessus, des retours en équerre 17, la tête de fixation 14 présente, latéralement, à un même niveau, pour la mise en place par simple encliquetage d'un tel élément d'ossature 11, deux encoches 25, qui, allongées sensiblement transversalement par rapport à l'axe longitudinal médian de la partie courante 13 de la suspente 12, sont orientées dos à dos l'une par rapport à l'autre, avec, faisant la jonction entre une extrémité médiane 26 relativement rectiligne perpendiculairement audit axe longitudinal médian et ces encoches 25, des bords 27 largement arrondis.Regarding the implementation of secondary framework elements 11 having, as indicated above, angle returns 17, the fixing head 14 has, laterally, at the same level, for the establishment by simple snap-fitting of such a framework element 11, two notches 25 which, elongated substantially transversely with respect to the median longitudinal axis of the main part 13 of the hanger 12, are oriented back to back, one with respect to the other, with, making the junction between a median end 26 relatively straight perpendicular to said median longitudinal axis and these notches 25, edges 27 largely rounded.

Dans la forme de réalisation représentée, la tête de fixation 14 présente en outre, entre ses encoches 25, sur l'axe longitudinal médian de l'ensemble, un perçage 28.In the embodiment shown, the fixing head 14 also has, between its notches 25, on the median longitudinal axis of the assembly, a bore 28.

Suivant l'invention, la tête de fixation 14 ainsi constituée est encadrée par une pointe 30 qui s'étend sensiblement dans le prolongement de la partie courante 13 de la suspente 12 et qui est pliable à l'équerre.According to the invention, the fixing head 14 thus formed is framed by a point 30 which extends substantially in the extension of the main part 13 of the hanger 12 and which is foldable at right angles.

Dans les formes de réalisation représentées sur les figures 1 à 9, cette pointe 30 est formée par deux languettes 29 qui sont chacune individuellement pliables à l'équerre, et qui, dans ces formes de réalisation, se rejoignent l'une l'autre au-delà de la tête de fixation 14.In the embodiments shown in the Figures 1 to 9, this tip 30 is formed by two tongues 29 which are each individually foldable at right angles, and which, in these embodiments, join one another beyond the fixing head 14 .

Situées l'une et l'autre à un même niveau, les lignes de pliage racine 31 de ces languettes 29, qui ont été matérialisées par des traits interrompus sur la figure 1, s étendent en-deçà des encoches 25 de la tête de fixation 14.Both located on the same level, the root fold lines 31 of these tabs 29, which have been shown by broken lines in FIG. 1, extend below the notches 25 of the fixing head 14.

Autrement dit, elles s'étendent entre la tête de fixation 14 et la partie courante 13 de la suspente 12 qu'elles affectent.In other words, they extend between the fixing head 14 and the running part 13 of the hanger 12 which they affect.

En pratique, et comme les encoches 25, elles s'étendent sensiblement transversalement par rapport à l'axe longitudinal médian de l'ensemble.In practice, and like the notches 25, they extend substantially transversely relative to the median longitudinal axis of the assembly.

Par leur contour intérieur à compter de leurs lignes de pliage racines 31, les languettes pliables 29 qui encadrent ainsi la tête de fixation 14 suivent, chacune pour moitié, au plus près, exception faite, évidemment, des encoches 25, le contour extérieur de cette tête de fixation 14.By their inner contour from their root fold lines 31, the foldable tabs 29 which thus frame the fixing head 14 follow, each for half, as closely as possible, except, of course, notches 25, the outer contour of this fixing head 14.

Au-delà de celle-ci, elles se côtoient ensuite l'une l'autre, suivant l'axe longitudinal médian de l'ensembleBeyond this, they then rub shoulders with each other, along the median longitudinal axis of the assembly

Dans la forme de réalisation représentée sur les figures 1 et 2, le contour extérieur de chacune de ces languettes pliables 29 est corollairement formé, d'une part, à compter de la ligne de pliage racine 31 correspondante, d'un bord 32 qui s'étend sensiblement parallèlement à l'axe longitudinal médian de l'ensemble, et, d'autre part, à la suite de ce bord 32, et en continuité avec celui-ci, d'un bord 33, qui, globalement oblique sur l'axe longitudinal médian de l'ensemble, recoupe en biais ce dernier.In the embodiment shown in Figures 1 and 2, the outer contour of each of these foldable tabs 29 is corollarily formed, on the one hand, from the corresponding root fold line 31, an edge 32 which s 'extends substantially parallel to the median longitudinal axis of the assembly, and, on the other hand, following this edge 32, and in continuity with this, of an edge 33, which, generally oblique to the 'median longitudinal axis of the assembly, crosses the latter at an angle.

Dans la forme de réalisation représentée sur les figures 1 et 2, ce bord 33 est rectiligne.In the embodiment shown in Figures 1 and 2, this edge 33 is straight.

De préférence, et tel que représenté, la suspente 12 suivant l'invention présente, en outre, en-deçà de sa tête de fixation 14, au moins une autre languette pliable à l'équerre 35.Preferably, and as shown, the hanger 12 according to the invention has, in addition, below its fixing head 14, at least one other foldable tongue at right angles 35.

Dans la forme de réalisation représentée sur les figures 1 et 2, il y a ainsi deux autres languettes pliables à l'équerre 35, et ces autres languettes pliables 35, dites ci-après par simple commodité languettes pliables intermédiaires, affectent la zone médiane 19 de la partie courante 13 de la suspente 12, en s'étendant en pleine surface dans celle-ci.In the embodiment shown in FIGS. 1 and 2, there are thus two other foldable tabs at right angles 35, and these other foldable tabs 35, said hereinafter by simple convenience, intermediate foldable tabs, affect the central zone 19 of the main part 13 of the hanger 12, extending into the full surface therein.

En pratique, dans cette forme de réalisation, venues d'un crevé de cette partie courante 13, elles s'étendent chacune respectivement à partir d'une ligne de pliage racine 36 perpendiculaire à l'axe longitudinal médian de l'ensemble, et, par l'un de leurs bords, elles se côtoient l'une l'autre le long de cet axe longitudinal médianIn practice, in this embodiment, coming from a puncture in this main part 13, they each extend respectively from a root fold line 36 perpendicular to the median longitudinal axis of the assembly, and, by one of their edges, they rub against each other along this median longitudinal axis

Dans la forme de réalisation représentée, les lignes de pliage racines 36 de ces languettes pliables intermédiaires 35 sont décalées l'une par rapport à l'autre suivant l'axe longitudinal médian de l'ensemble, et leurs extrémités libres sont globalement arrondies en demi-cercle.In the embodiment shown, the root fold lines 36 of these intermediate foldable tabs 35 are offset relative to each other along the median longitudinal axis of the assembly, and their free ends are generally rounded in half -circle.

Dans la forme de mise en oeuvre illustrée sur les figures 3A, 3B, 3C, il a été supposé que, entre les chevrons 10 et les fourrures constituant les éléments d'ossature secondaire 11, devaient successivement être implantés, parallèlement l'un à l'autre, deux doublages thermo-acoustiques 38, 39.In the embodiment illustrated in FIGS. 3A, 3B, 3C, it has been assumed that, between the rafters 10 and the furs constituting the secondary framework elements 11, must successively be installed, parallel to one another. 'other, two thermo-acoustic doublings 38, 39.

De manière connue en soi, ces doublages 38, 39 sont constitués à l'aide de plaques, panneaux ou rouleaux en matériau isolant à jointoyer deux à deux dans un même plan.In a manner known per se, these doublings 38, 39 are formed using plates, panels or rolls of insulating material to be joined two by two in the same plane.

Cela étant, il est procédé comme suit.However, the procedure is as follows.

Dans un premier temps, figure 3A, il est procédé à la fixation, sur l'ossature primaire de support que constituent les chevrons 10, du nombre de suspentes 12 nécessaires à l'accrochage des éléments d'ossature secondaire 11 à mettre en oeuvre, en établissant bien entendu toutes à un même niveau ces suspentes 12.Firstly, in FIG. 3A, the number of hangers 12 necessary for the attachment of the secondary frame elements 11 to be used is fixed on the primary support framework constituted by the rafters 10, by of course establishing all of these lines at the same level 12.

Dans un deuxième temps, il est procédé, ensuite, à la mise en place du premier doublage thermo-acoustique 38, par engagement, sur les suspentes 12, des plaques, panneaux ou rouleaux constitutifs de celui-ci.In a second step, it is then carried out, the establishment of the first thermo-acoustic lining 38, by engagement, on the lines 12, plates, panels or constituent rollers thereof.

Ainsi qu'il est aisé de le comprendre, la pointe 30 que forment alors à l'extrémité des suspentes 12 les languettes pliables 29 qui encadrent leur tête de fixation 14 facilite la pénétration, par simple pression, de ces plaques, panneaux ou rouleaux, et, eu égard à la texture usuellement fibreuse du matériau constitutif de ceux-ci, cette pénétration se fait aisément, sans en entraîner une quelconque détériorationAs is easy to understand, the point 30 which then forms at the end of the lines 12 the foldable tabs 29 which frame their fixing head 14 facilitates the penetration, by simple pressure, of these plates, panels or rollers, and, having regard to the usually fibrous texture of the material from which they are made, this penetration takes place easily, without causing any deterioration

De même, le chanfrein 24 biseautant les raidisseurs latéraux 20 de la partie courante 13 des suspentes 12 facilite cette pénétration.Similarly, the chamfer 24 bevelling the lateral stiffeners 20 of the main part 13 of the lines 12 facilitates this penetration.

Après le franchissement, par le doublage thermo-acoustique 38 ainsi mis en place, de la ligne de pliage racine 36 des languettes pliables intermédiaires 35 des suspentes 12, ces languettes pliables 35 sont pliées à l'équerre, figure 3A, pour la retenue de ce permier doublage thermo-acoustique 38.After crossing, by the thermo-acoustic lining 38 thus put in place, of the root fold line 36 of the intermediate foldable tabs 35 of the lines 12, these foldable tabs 35 are bent at right angles, FIG. 3A, for retaining this first thermo-acoustic doubling 38.

Dans un troisième temps, il est procédé de même pour le deuxième doublage thermo-acoustique 39, la retenue de celui-ci étant alors assurée par les languettes pliables 29 qui encadrent la tête de fixation 14 des suspentes 12, figure 3B.In a third step, the same procedure is followed for the second thermo-acoustic lining 39, the retention of the latter then being ensured by the foldable tabs 29 which frame the fixing head 14 of the lines 12, FIG. 3B.

Pour ces languettes pliables 29 comme pour les languettes pliables intermédiaires 35, le pliage est préférentiellement effectué en sens opposé d'une de ces languettes à l'autre par rapport à la suspente 12 à laquelle elles appartiennent, en sorte que, après ce pliage, l'une de ces languettes s'étend en saillie d'un premier côté de cette suspente 12 et l'autre en saillie de l'autre côté de celle-ci, comme représenté isolément à la figure 4.For these foldable tabs 29 as for the intermediate foldable tabs 35, the folding is preferably carried out in the opposite direction from one of these tabs to the other relative to the hanger 12 to which they belong, so that, after this folding, one of these tabs extends projecting from one side of this hanger 12 and the other projecting from the other side thereof, as shown in isolation in FIG. 4.

Quoi qu'il en soit, le pliage à l'équerre des languettes pliables 29 encadrant la tête de fixation 14 des suspentes 12 conduit à un dégagement de cette tête de fixation 14.Whatever the case, the folding of the foldable tongues 29 square to the fixing head 14 of the lines 12 leads to a release of this fixing head 14.

Il suffit donc, ensuite, dans un quatrième temps, d'encliqueter, sur la tête de fixation 14 ainsi dégagée des suspentes 12, les fourrures constituant les éléments d'ossature secondaire 11, figure 3C.It is therefore sufficient, then, in a fourth step, to snap onto the fixing head 14 thus released from the lines 12, the furs constituting the secondary framework elements 11, FIG. 3C.

Dans la variante de réalisation représentée sur les figures 5 et 6, les raidisseurs 20 flanquant latéralement la partie courante 13 de la suspente 12 suivant l'invention sont simplement chacun individuellement formés par un bord relevé formant un dièdre obtus avec la zone médiane 19 de cette partie courante 13, ce qui, au stockage, facilite l'empilage d'une telle suspente 12.In the alternative embodiment shown in FIGS. 5 and 6, the stiffeners 20 laterally flanking the main part 13 of the hanger 12 according to the invention are simply each individually formed by a raised edge forming an obtuse dihedral with the median zone 19 of this main part 13, which, during storage, facilitates stacking of such a hanger 12.

Par exemple, l'angle du dièdre que forment alors ainsi ses raidisseurs 20 est compris entre 90 et 140°.For example, the angle of the dihedral which thus form its stiffeners 20 is between 90 and 140 °.

Conjointement, dans cette variante de réalisation, la zone médiane 19 de la partie courante 13 de la suspente 12 suivant l'invention est elle-même raidie par des nervures 50, à profil transversal en demi-cercle, qui, parallèlement l'une à l'autre, courent sur toute sa hauteur, jusqu'à la racine de la tête de fixation 14, au voisinage des raidisseurs 20, en encadrant les languettes pliables intermédiaires 35, et en faisant saillie du même côté de la zone médiane 19 que les raidisseurs 20 flanquant latéralement celle-ci.At the same time, in this variant embodiment, the middle zone 19 of the main part 13 of the hanger 12 according to the invention is itself stiffened by ribs 50, with a transverse profile in a semicircle, which, parallel to one the other run over its entire height, up to the root of the fixing head 14, in the vicinity of the stiffeners 20, by framing the intermediate foldable tabs 35, and projecting from the same side of the median zone 19 as the stiffeners 20 laterally flanking it.

En pratique, dans cette variante de réalisation, l'extrémité libre des languettes pliables intermédiaires 35 est droite.In practice, in this alternative embodiment, the free end of the intermediate foldable tabs 35 is straight.

Enfin, dans cette variante de réalisation, le bord 33 des languettes pliables 29 qui encadrent la tête de fixation 14 est cintré, avec sa concavité dirigée vers l'extérieur.Finally, in this alternative embodiment, the edge 33 of the foldable tabs 29 which frame the fixing head 14 is curved, with its concavity directed towards the outside.

En outre, la pointe 30 que forment ces languettes pliables 29 est tronquée.In addition, the tip 30 formed by these foldable tabs 29 is truncated.

Dans la variante de réalisation représentée sur les figures 7 à 9, les languettes pliables intermédiaires 35 s'étendent latéralement, en affectant chacune respectivement les bords de la partie courante 13 de la suspente 12 suivant l'invention, bords qui, en l'espèce, et suivant la variante de réalisation précédente, sont des bords relevés constituant des raidisseurs 20.In the alternative embodiment shown in Figures 7 to 9, the intermediate foldable tabs 35 extend laterally, each affecting respectively the edges of the running part 13 of the hanger 12 according to the invention, edges which, in this case , and according to the previous embodiment, are raised edges constituting stiffeners 20.

En outre, dans cette variante de réalisation, la ligne de pliage racine 36 de ces languettes pliables interémdiaires 35, et il en est de même pour la ligne de pliage racine 31 des languettes pliables 29 encadrant la tête de fixation 14, est matérialisée pr un décrochement.In addition, in this alternative embodiment, the root fold line 36 of these intermediate foldable tabs 35, and the same is true for the root fold line 31 of foldable tabs 29 framing the fixing head 14, is materialized for a step.

Autrement dit, le plan suivant lequel s'étend une languette pliable intermédiaire 35 s'écarte du plan suivant lequel s'étend le bord relevé formant raidisseur 20 dont elle est issue.In other words, the plane along which extends an intermediate foldable tongue 35 departs from the plane along which extends the raised edge forming a stiffener 20 from which it originates.

De même, les plans suivant lesquels s'étendent les languettes pliables 29 s'écartent du plan de la zone médiane 19 de la partie courante 13, d'un premier côté de ce dernier pour l'une de ces languettes pliables 29, et de l'autre côté pour l'autre de celles-ci.Likewise, the planes along which the foldable tabs extend 29 deviate from the plane of the central zone 19 of the main part 13, on a first side of the latter for one of these foldable tabs 29, and the other side for the other of these.

Dans la variante de réalisation représentée sur la figure 10, la pointe 30 qui encadre la tête de fixation 14 de la suspente 12 suivant l'invention est d un seul tenant.In the variant embodiment shown in FIG. 10, the tip 30 which frames the fixing head 14 of the hanger 12 according to the invention is in one piece.

La mise en oeuvre de ces diverses variantes de réalisation est du même type que celle décrite en détail en référence aux figures 3A, 3B, 3C.The implementation of these various embodiments is of the same type as that described in detail with reference to Figures 3A, 3B, 3C.

Bien entendu, 1a présente invention ne se limite pas aux formes de réalisation décrites et représentées, mais englobe toute variante d'exécution et/ou de combinaison de leurs divers éléments.Of course, the present invention is not limited to the embodiments described and shown, but encompasses any variant and / or combination of their various elements.

En particulier, si, dans ce qui précède, la ligne de pliage racine des languettes pliables intermédiaires s'étend en-deçà de leur extrémité libre par rapport à la tête de fixation de la suspente, ce qui en autorise le pliage dès que le doublage thermo-acoustique concerné est à niveau avec cette ligne de pliage racine, il est parfaitement envisageable que cette ligne de pliage racine soit entre l'extrémité libre de ces languettes pliables intermédiaires et la tête de fixation, notamment lorsque le doublage thermo-acoustique concerné peut être l'objet d'une certaine compression.In particular, if, in the above, the root fold line of the intermediate foldable tabs extends below their free end relative to the fastening head of the hanger, which allows folding as soon as the doubling thermo-acoustic concerned is level with this root fold line, it is perfectly conceivable that this root fold line is between the free end of these intermediate foldable tabs and the fixing head, in particular when the thermo-acoustic lining concerned can be subject to some compression.

En outre, le domaine d'application de l'invention n'est pas simplement limité à celui de la seule suspension d'un plafond, mais il s'étend aussi bien d une manière plus générale à celui de l'accrochage d'un quelconque élément d'ossature à un quelconque support, par exemple pour un plafond rampant, un piédroit ou tout autre doublage incliné ou vertical.Furthermore, the field of application of the invention is not simply limited to that of the sole suspension of a ceiling, but it also extends in a more general to that of the attachment of any frame element to any support, for example for a creeping ceiling, a pedestal or any other inclined or vertical lining.

A cet égard, il est à observer que c'est par simple commodité que, de manière d'ailleurs conventionnelle, le mot de "suspente" a ici été utilisé pour la désignation de l'objet de l'invention.In this regard, it should be noted that it is for the sake of convenience that, moreover, conventionally, the word "hanger" has been used here for the designation of the subject of the invention.

D'une manière plus générale, il s'agit d'un organe d'accrochage dont l'orientation, en service, peut être quelconque.More generally, it is a fastening member whose orientation, in service, can be arbitrary.
