Description

La présente invention concerne le domaine de la solidarisation d'éléments avec des surfaces support, et a pour objet un dispositif de fixation de poutres creuses ou d'éléments creux similaires à usage décoratif.The present invention relates to the field of joining of elements with support surfaces, and a for a device for fixing hollow beams or similar hollow elements for decorative use.

Les techniques actuelles de construction de locaux à usage d'habitation privilégient les plafonds à surface plane.Current building construction techniques for residential use favor surface ceilings plane.

Si, pour des raisons décoratives, on veut réaliser des plafonds à poutres ou solives apparentes en bois, ou en produits de substitution, il est avantageux d'utiliser des produits creux fabriqués à partir d'éléments en bois assemblés par collage ou à partir de matière synthétique moulée.If, for decorative reasons, we want to realize beamed ceilings or exposed joists in wood, or as a substitute, it is advantageous to use hollow products made from elements of wood assembled by gluing or from material molded synthetic.

Ces produits se présentent en général sous forme de profilés en U que l'on fixe avec des moyens classiques (clous, vis, chevilles) sur des plafonds plans.These products generally come in the form U-shaped profiles that are fixed with conventional means (nails, screws, dowels) on flat ceilings.

Ce travail de fixation est délicat et peu commode car il exige des perçages, des vissages ou des clouages proches des plafonds, très souvent fragiles par nature.This fixing work is delicate and inconvenient because it requires drilling, screwing or nails close to ceilings, very often fragile by nature.

D'autre part, ces moyens classiques laissent des traces sur les surfaces apparentes de ces éléments creux et exigent un travail de bouchage et de retouche.On the other hand, these conventional means leave traces on the visible surfaces of these hollow elements and require capping and touch-up work.

Par ailleurs, on connait également différents modes de fixation, dits "invisibles", mettant en oeuvre des éléments crantés complémentaires ou des moyens a encliquetage.Besides, we also know different fixing methods, called "invisible", using complementary notched elements or snap-fastening means.

Néanmoins, ces systèmes connus présentent généralement plusieurs des inconvénients suivants, à savoir, pas de possibilité de démontage sans détérioration, une force de solidarisation d'intensité limitée, un aménagement spécifique des éléments a solidariser, un poids propre et un prix de revient élevés, la présence d'un interstice entre l'élément à fixer (poutre creuse par exemple) et la surface support (plafond par exemple), ou encore l'absence d'une pression d'application permanente de l'élément à fixer contre la surface support. However, these known systems generally exhibit several of the following disadvantages, namely, no possibility of disassembly without deterioration, a joining force of limited intensity, development specific elements to be joined, a weight clean and a high cost price, the presence of a gap between the element to be fixed (hollow beam by example) and the support surface (ceiling for example), or still no permanent application pressure of the element to be fixed against the support surface.

Par le document DE-U-89 00374, on connaít un dispositif de fixation pour des poutres pleines, partiellement évidées par rainurage. Ce dispositif est composé, d'une part, d'un ou de plusieurs éléments mâles crantés, fixés au plafond et, d'autre part, de deux éléments en forme de U montés dans la poutre et réalisant une ouverture ou un passage cranté(e) destiné(e) à coopérer avec l'élément mâle et à bloquer ce dernier après son emboítement.Document DE-U-89 00374 discloses a fixing device for solid beams, partially hollowed out by grooving. This device is composed, on the one hand, of one or more notched male elements, fixed to the ceiling and, on the other hand, two U-shaped elements mounted in the beam and achieving an opening or a notched passage intended to cooperate with the male element and to block the latter after its nesting.

Néanmoins, la fixation ainsi obtenue n'est pas amovible, sauf à détruire l'un ou les deux éléments constitutifs précités, et ne permet pas de plaquer en permanence la poutre à solidariser contre la surface de montage et d'assurer un maintien en application constant de ladite poutre.However, the fixing thus obtained is not removable, except at destroy one or both of the aforementioned components, and does not allow to tackle permanently the beam to be secured against the mounting surface and ensure a maintaining constant application of said beam.

De plus, le document DE-A-2 239 584 décrit un dispositif de solidarisation rapide à pression, pour le montage de caches sur des machines. Ce dispositif est constitué, d'une part, par un socle pourvu d'une mâchoire formant pince et, d'autre part, par un élément déformable présentant une section en Ω et destiné à être introduit de force dans ladite mâchoire.In addition, document DE-A-2 239 584 describes a device for fast connection with pressure, for mounting covers on machines. This device consists, on the one hand, by a base provided with a jaw forming clamp and, on the other hand, by a deformable element having a section in Ω and intended to be forced into said jaw.

Les configurations de ces deux éléments et leur coopération sont telles qu'ils permettent de réaliser, en plus de la fonction de fixation, une fonction de charnière à pivotement limité.The configurations of these two elements and their cooperation are such that they make it possible to carry out, in addition to the fixing function, a function limited pivot hinge.

Toutefois, ce dispositif de solidarisation ne permet pas d'assurer, ni a fortiori de maintenir, un contact intime entre les différentes parties à assembler.However, this joining device does not ensure, nor has a fortiori to maintain, an intimate contact between the different parts to be assembled.

Par ailleurs, le document FR-E-88 291 divulgue un dispositif de fixation de panneaux de revêtement, comprenant, d'une part, un clip déformable pourvu d'un téton en forme de coin destiné à être introduit entre les lèvres d'un profilé de fixation et, d'autre part, des éléments suspendus solidarisés aux panneaux de revêtement et destinés à être au moins partiellement introduits dans la partie ouverte du clip opposé au téton, en écartant les jambes ou parois latérales dudit clip.Furthermore, document FR-E-88,291 discloses a device for fixing of covering panels, comprising, on the one hand, a deformable clip provided with a wedge-shaped nipple intended to be inserted between the lips of a fixing profile and, on the other hand, suspended elements secured to the cladding panels and intended to be at least partially introduced into the open part of the clip opposite the nipple, spreading the legs or side walls said clip.

L'accrochage sur ledit profilé de fixation est réalisé par la venue en prise des lèvres formant les extrémités des ailes latérales de ce dernier dans un étranglement situé à l'arrière de la base du téton.The attachment to said fixing profile is achieved by the coming in catch of the lips forming the ends of the lateral wings of the latter in a constriction located at the rear of the nipple base.

Néanmoins, ce dispositif de fixation ne permet pas non plus d'obtenir l'application de l'élément à fixer contre une surface support et le maintien intime constant dudit élément contre ladite surface. However, this fixing device also does not make it possible to obtain applying the element to be fixed against a support surface and keeping it intimate constant of said element against said surface.

La présente invention a notamment pour but de remédier aux inconvénients précités, l'idée essentielle étant d'utiliser l'espace disponible à l'intérieur de ces éléments creux afin d'y adapter un dispositif de fixation réalisant une solidarisation amovible, sans interstice, entre le ou les éléments creux et la surface support, ce tout en exerçant une pression constante appliquant le ou les éléments creux contre ladite surface support.The object of the present invention is in particular to remedy the aforementioned drawbacks, the essential idea being to use the space available inside these hollow elements in order to adapt a fixing device thereto achieving a removable connection, without gaps, between the hollow element (s) and the support surface, this while exerting constant pressure applying the or the hollow elements against said support surface.

Cette disposition devra permettre, après fixation des éléments constituant le dispositif selon l'invention, de mettre en place lesdits éléments creux par simple enclenchement par pression, la solidarisation ainsi obtenue présentant une résistance à la traction élevée.This provision should allow, after fixing elements constituting the device according to the invention, to set up said hollow elements by simple snap-on, the connection thus obtained with high tensile strength.

En outre, les parties constitutives dudit dispositif de fixation devront pouvoir être mis en place, de manière réversible, respectivement sur la surface support ou sur les éléments creux à solidariser et permettre la fixation d'éléments creux sur des surfaces support horizontales, verticales ou obliques. In addition, the constituent parts of said device fixing must be able to be put in place, reversibly, respectively on the support surface or on the hollow elements to be joined and allow the fixing of hollow elements on horizontal support surfaces, vertical or oblique.

A cet effet, la présente invention a pour objet un dispositif de fixation d'éléments creux décoratifs présentant les caractéristiques mentionnées dans la revendication 1. To this end, the present invention relates to a device for fixing decorative hollow elements having the characteristics mentioned in claim 1.

L'invention sera mieux comprise grâce à la description ci-après, qui se rapporte à des modes de réalisation préférés, donnés à titre d'exemples non limitatifs, et expliqué avec référence aux dessins schématiques annexés, dans lesquels :

  • la figure 1 est une vue en élévation latérale et en coupe d'un premier mode de réalisation du dispositif de fixation conforme à l'invention, appliqué à la fixation d'une poutre creuse à un plafond et,
  • la figure 2 est une vue en élévation latérale et en coupe du dispositif de fixation conforme à l'invention, selon un deuxième mode de réalisation.
    • The invention will be better understood thanks to the description below, which relates to preferred embodiments, given by way of nonlimiting examples, and explained with reference to the appended schematic drawings, in which:
  • FIG. 1 is a side elevational view in section of a first embodiment of the fixing device according to the invention, applied to the fixing of a hollow beam to a ceiling and,
  • Figure 2 is a side elevational view in section of the fixing device according to the invention, according to a second embodiment.

    • Conformément à l' invention, et comme le montrent les figures 1 et 2 des dessins annexés, le dispositif de fixation est principalement constitué par deux parties, une partie mâle 5, 6 et une partie femelle 3, 4, l'une quelconque desdites parties 3, 4 ou 5, 6 étant fixée, avant la pose de l'élément creux 1, à l'aide de moyens classiques tels que clous, vis, chevilles ou similaires, sur la surface support 2 et l'autre desdites parties 5, 6 ou 3, 4 étant montée sur la face intérieure de l'élément creux 1 opposée à la surface support 2 lors de la pose de l'élément creux 1, les deux parties 3, 4 et 5, 6 en s'emboítant assurant une fixation démontable de ce dernier.According to the invention, and as shown Figures 1 and 2 of the accompanying drawings, the device fixing consists mainly of two parts, a male part 5, 6 and a female part 3, 4, one any one of said parts 3, 4 or 5, 6 being fixed, before installing the hollow element 1, using means conventional such as nails, screws, dowels or the like, on the support surface 2 and the other of said parts 5, 6 or 3, 4 being mounted on the inner face of the element hollow 1 opposite to the support surface 2 when installing the hollow element 1, the two parts 3, 4 and 5, 6 by fitting together ensuring a removable fixing of the latter.

    La partie femelle est composée, d'une part, par une pièce 4 comportant deux bras 4b élastiquement déformables, pouvant être écartés par force et se terminant par des lèvres d'appui 4a et, d'autre part, d'une platine ou d'un étrier 3 solidarisé(e) à la pièce 4 au niveau de son âme 4c et pourvu(e) d'orifices pour le passage de clous, vis, chevilles ou similaires (Figures 1 et 2).The female part is composed, on the one hand, by a part 4 comprising two elastically deformable arms 4b, may be forcefully discarded and ending with support lips 4a and, on the other hand, a plate or a stirrup 3 secured to part 4 at its core 4c and provided with holes for the passage of nails, screws, dowels or the like (Figures 1 and 2).

    Comme le montrent également les figures 1 et 2 des dessins annexés, la partie mâle 5, 6 est avantageusement composée, d'une part, d'un corps creux 5 pour l'écartement des lèvres d'appui 4a des bras 4b de la pièce 4 et la solidarisation de cette dernière par emboítement à enclenchement et, d'autre part, d'une platine ou de deux pattes 6 de forme rectangulaire et comportant des orifices pour le passage de clous, vis, rivets ou similaires.As also shown in Figures 1 and 2 of the accompanying drawings, the male part 5, 6 is advantageously composed, on the one hand, of a hollow body 5 for spacing support lips 4a of arms 4b of part 4 and the joining of the latter by interlocking to engagement and, on the other hand, a turntable or two legs 6 of rectangular shape and having orifices for the passage of nails, screws, rivets or the like.

    Conformément à une caractéristique de l'invention, représentée aux figures 1 et 2 des dessins annexés, le corps creux 5 comporte, au niveau de son extrémité opposée à la platine ou aux pattes 6, une partie 5a conique ou en forme de coin, débutant par une pointe arrondie 5b et se terminant par deux zones longitudinales bossues 5c définissant la base et l'écartement maximal de la paroi de ladite partie 5a.In accordance with a characteristic of the invention, shown in Figures 1 and 2 of the accompanying drawings, the hollow body 5 comprises, at its end opposite the plate or the legs 6, a conical part 5a or wedge-shaped, starting with a rounded point 5b and ending in two hunched longitudinal zones 5c defining the base and the maximum spacing of the wall of said part 5a.

    Cette partie 5a permet, par conséquent, lors de l'application des éléments creux 1 contre la surface support 2 et, donc, de l'appui des parties mâles 5, 6 sur les parties femelles 3, 4, d'écarter progressivement les lèvres d'appui 4a des pièces 4 en vue de l'introduction du corps creux 5 entre les bras 4b de la pièce 4. Puis ladite partie 5a assure le maintien, par emboítement partiel à enclenchement, dudit corps creux 5 dans ladite pièce 4 après que lesdites lèvres d'appui 4a aient dépassé les zones longitudinales bossues 5c de ladite partie 5a, du fait de la force de serrage résultant de la déformation des bras 4b, pressant lesdites lèvres d'appui 4a contre la paroi du corps creux 5 et s'opposant à un déplacement de celles-ci en direction des zones longitudinales bossues 5c et, par conséquent, à une rétraction de la partie mâle.This part 5a therefore allows, during applying the hollow elements 1 against the support surface 2 and, therefore, the support of the male parts 5, 6 on the female parts 3, 4, to gradually separate the lips 4a support parts 4 for the introduction of hollow body 5 between the arms 4b of the part 4. Then said part 5a ensures the maintenance, by partial nesting engagement of said hollow body 5 in said part 4 after that said support lips 4a have exceeded the hunched longitudinal zones 5c of said part 5a, of the made of clamping force resulting from deformation arms 4b, pressing said support lips 4a against the wall of the hollow body 5 and opposing a displacement of these in the direction of the hunched longitudinal zones 5c and, therefore, a retraction of the male part.

    Comme le montrent également les figures 1 et 2 des dessins annexés, le corps creux 5 présente, au delà des zones longitudinales bossues 5c, deux portions de paroi symétriques 5d inclinées ou incurvées de manière convergente et aboutissant à deux renfoncements 5e.As also shown in Figures 1 and 2 of the accompanying drawings, the hollow body 5 has, beyond hunched longitudinal zones 5c, two wall portions symmetrical 5d inclined or curved in a convergent way and leading to two 5th recesses.

    Lorsque, après dépassement des zones longitudinales bossues 5c, les lèvres d'appui 4a sont appliquées contre les portions de paroi 5d du corps creux 5, elles ont tendance à se déplacer, sous l'action du serrage réalisé par les bras 4b, en direction des fonds des renfoncements 5e, entraínant ainsi la pièce 4 et, par conséquent, lorsque celle-ci est solidarisée à l'élément creux 1, également ce dernier en direction de la surface support 2.When, after passing the longitudinal zones hunchbacks 5c, the support lips 4a are applied against the wall portions 5d of the hollow body 5, they tend to move under the action of tightening by arms 4b, towards the depths of the recesses 5th, resulting in part 4 and, therefore, when the latter is secured to the hollow element 1, also the latter in the direction of the support surface 2.

    Il résulte de ce qui précède qu'il conviendra, dans la pratique, de choisir les parties mâles 5, 6 et femelles 3, 4 et de les solidariser à l'élément creux 1 et à la surface support 2 de telle manière que, lorsque l'élément creux 1 vient en appui, au niveau de sa face ouverte, sur la surface support 2, les lèvres d'appui 4a reposent contre les portions de paroi symétriques 5d.It follows from the above that it will be appropriate, in practice, to choose the male parts 5, 6 and females 3, 4 and secure them to the hollow element 1 and to the support surface 2 so that when the hollow element 1 comes to bear, at its face open, on the support surface 2, the support lips 4a rest against the symmetrical wall portions 5d.

    Dans ces conditions, ledit élément creux 1 sera en permanence pressé intimement contre ladite surface support 2 avec une intensité dépendant de la force de rappel élastique des bras 4d et de la conformation et de l'inclinaison des portions de paroi symétriques 5d, assurant également un assujettissement par friction dudit élément creux 1 dans sa direction longitudinale.Under these conditions, said hollow element 1 will permanently pressed intimately against said support surface 2 with an intensity depending on the restoring force elastic 4d arms and conformation and tilt symmetrical wall portions 5d, also ensuring a friction subjection of said element hollow 1 in its longitudinal direction.

    En vue d'obtenir l'effet susvisé, les parties mâles 5, 6 et/ou femelles 3, 4 pourront être solidarisées à l'élément creux 1 ou à la surface support 2 par l'intermédiaire de cales ou de gabarits adaptés.In order to obtain the above effect, the parties males 5, 6 and / or females 3, 4 may be joined to the hollow element 1 or to the support surface 2 via suitable shims or jigs.

    Selon un mode de réalisation préféré de l'invention, le corps creux 5 et la pièce 4 présentent une section profilée obtenue par pliage et une forme sensiblement rectangulaire, ainsi que des parois de faible épaisseur consistant préférentiellement en de l'acier, permettant d'obtenir un dispositif de fixation présentant une résistance élevée et un poids faible.According to a preferred embodiment of the invention, the hollow body 5 and the part 4 have a section shaped obtained by folding and a shape substantially rectangular, as well as thin walls preferably consisting of steel, allowing to obtain a fastening device having a resistance high and low weight.

    Néanmoins, ces éléments pourront également être obtenus par moulage par injection d'un matériau plastique, notamment lorsque les éléments creux 1 sont également réalisé en un matériau synthétique.However, these elements may also be obtained by injection molding of a plastic material, especially when the hollow elements 1 are also made of synthetic material.

    En outre, le corps creux 5 peut également être réalisé d'un seul tenant avec les pattes 6 à partir d'une seule plaque de tôle d'acier, par pliage, emboutissage et soudage mutuel des parois au niveau des pattes 6, les renfoncements 5e assurant alors essentiellement un rôle de rigidification et de raidissement (figure 2) et les pattes 6 une fonction supplémentaire de butée latérale pour la pièce 4.In addition, the hollow body 5 can also be made in one piece with legs 6 from a single sheet steel plate, by bending, stamping and mutual welding of the walls at the legs 6, the 5th recesses then essentially ensuring a role of stiffening and stiffening (Figure 2) and the legs 6 an additional lateral stop function for the room 4.

    Par ailleurs, la pièce 4 peut avantageusement être réalisée en tôle d'acier préformée et trempée, permettant d'obtenir une force de rappel très élevée, ce même en cas de faible épaisseur.Furthermore, the part 4 can advantageously be made of preformed and hardened sheet steel, allowing to obtain a very high restoring force, even in case of thin thickness.

    De manière préférentielle et comme le montre la figure 1 des dessins annexés, la partie mâle 5, 6 est solidarisée au plafond ou au mur 2, notamment, lorsque les plafond 2 est formé de plaques plâtrées, à l'aide de vis spécifiquement adaptées dont les emplacements ont été préalablement repérés, cette solidarisation s'effectuant rapidement du fait de l'absence des éléments creux 1 (poutres).Preferably and as shown in the Figure 1 of the accompanying drawings, the male part 5, 6 is secured on the ceiling or on the wall 2, in particular, when the ceiling 2 is made of plastered plates, using screws specifically adapted whose locations have been previously identified, this joining taking place quickly due to the absence of hollow elements 1 (beams).

    Ensuite ces derniers sont emboítés sur lesdites parties mâles 5, 6 au moyen de parties femelles 3, 4 préalablement fixées à l'intérieur desdits éléments creux 1 à des intervalles identiques à ceux séparant lesdites parties mâles 5, 6.Then the latter are fitted on said male parts 5, 6 by means of female parts 3, 4 previously fixed inside said hollow elements 1 at intervals identical to those separating the said male parts 5, 6.

    Par conséquent, le dispositif de fixation objet de l'invention facilite la mise en place d'éléments creux, notamment de poutres ou solives creuses à usage décoratif sans que les éléments de fixation soient apparents et sans que subsistent ou qu'apparaissent des interstices au niveau des surfaces d'assemblage en contact.Therefore, the object fixing device of the invention facilitates the placement of hollow elements, in particular hollow beams or joists for decorative use without the fasteners being visible and without that there remain or that there are gaps at the level assembly surfaces in contact.

    De plus, cette mise en place peut être réalisée par une personne professionnelle, lesdites poutres ou solives pouvant en outre, à tout moment, être aisément démontées et, ultérieurement, remontées par simple traction, respectivement pression.In addition, this installation can be carried out by a professional person, said beams or joists can also be easily dismantled and subsequently reassembled by simple pull, respectively pressure.

    Bien entendu, l'invention n'est pas limitée aux modes de réalisation décrits et représentés aux dessins annexés. Des modifications restent possibles, notamment du point de vue de la constitution des divers éléments ou par substitution d'équivalents techniques, sans sortir pour autant du domaine de protection de l'invention.Of course, the invention is not limited to embodiments described and shown in the drawings attached. Modifications remain possible, in particular from point of view of the constitution of the various elements or by substitution of technical equivalents, without going out for as much of the scope of protection of the invention.
