Description

Domaine technique :Technical area :

La présente invention concerne une fausse paroi constituée d'une toile qui est tendue par sa périphérie sur des éléments supports fixés sur les murs ou sur le plafond d'un local.The present invention relates to a false wall consisting of a canvas which is stretched by its periphery on support elements fixed to the walls or to the ceiling of a room.

Technique antérieure : Prior art :

On connaît différents types de fausses parois murales, et notamment des faux plafonds qui sont ainsi constitués d'une lisse métallique ou en matière de synthèse qui est pourvue d'éléments de maintien aptes à coopérer avec des moyens de maintien complémentaires prévus en périphérie de la toile. Ces moyens de maintien peuvent être constitués de lisses apparentes, ou comme dans le brevet EP-B-0338925 par des lisses qui sont dissimulées, au moins en partie, aux yeux des utilisateurs par la toile elle-même. D'autres exemples de lisses dissimulées sont également décrits dans les demandes de brevet EP0546971 et DE3329542 .Various types of false wall are known, and in particular false ceilings which thus consist of a metal heddle or of synthetic material which is provided with holding elements capable of cooperating with complementary holding means provided at the periphery of the canvas. These holding means may consist of visible beams, or as in the patent EP-B-0338925 by beams which are hidden, at least in part, from the eyes of the users by the canvas itself. Other examples of hidden beams are also described in patent applications EP0546971 and DE3329542 .

Lorsque les surfaces des plafonds ou des parois murales sont importantes, on dispose en travers de ces derniers des éléments séparateurs qui sont en fait constitués de lisses doubles permettant d'assurer de part et d'autre le maintien de la toile. Ces éléments séparateurs, même lorsqu'ils font appel à des lisses du type mentionné précédemment, comme étant du type dit invisible présentent néanmoins un écart, ou espace, entre deux parties de toile adjacentes. Bien entendu lorsqu'un tel espace se trouve en périphérie de la pièce, cet espace est d'autant plus acceptable sur le plan de l'esthétique qu'il est perçu avec moins d'acuité par les utilisateurs de la pièce.When the surfaces of the ceilings or wall walls are large, there are separating elements across the latter which are in fact made up of double healds making it possible to maintain the canvas on both sides. These separating elements, even when using healds of the type mentioned above, as being of the so-called invisible type nevertheless have a gap, or space, between two adjacent canvas parts. Of course when such a space is on the periphery of the room, this space is all the more acceptable in terms of aesthetics as it is perceived with less acuity by the users of the room.

La présente invention a pour but de proposer une lisse séparateur mettant en oeuvre des éléments profilés de type dit invisible permettant de réduire de façon notable l'écartement existant entre deux éléments de toile adjacents, jusqu'à le rendre quasi nul, les toiles étant en contact bord à bord.The object of the present invention is to provide a smooth separator using profiled elements of the so-called invisible type, making it possible to significantly reduce the spacing existing between two adjacent fabric elements, until it becomes almost zero, the fabrics being edge to edge contact.

Résumé de l'inventionSummary of the invention

A cet égard, la présente invention a pour objet une fausse paroi telle que définie dans la revendication indépendante 1, 4 ou 5, tandis que des variantes de réalisation sont exposées dans les revendications dépendantes.In this regard, the present invention relates to a false wall as defined in independent claim 1, 4 or 5, while alternative embodiments are set out in the dependent claims.

On comprend bien que le dispositif défini dans les revendications présente plusieurs avantages.It is understood that the device defined in the claims has several advantages.

Tout d'abord, il permet de mettre en commun, pour chacun des deux ensembles de maintien l'espace nécessaire au passage de la bordure périphérique de la toile.First of all, it makes it possible to pool, for each of the two holding assemblies the space necessary for the passage of the peripheral edge of the fabric.

Ensuite, la présente invention permet également au technicien-poseur, de ne recourir qu'à la seule spatule qu'il utilise habituellement pour la pose des plafonds tendus pour solidariser les deux profilés des lisses séparateurs.Then, the present invention also allows the technician-installer, to have recourse only to the only spatula which he usually uses for the laying of stretch ceilings to secure the two profiles of the smooth separators.

Description détaillée de l'inventionDetailed description of the invention

On a représenté de façon schématique sur les figure 2, 4 et 6 un faux plafond suivant l'invention qui est constitué d'une lisse séparateur 1 qui assure le maintien de deux éléments de toile tendue 4, respectivement 4a et 4b.We have represented schematically on the figure 2 , 4 and 6 a false ceiling according to the invention which consists of a smooth separator 1 which ensures the maintenance of two stretched canvas elements 4, 4a and 4b respectively.

La lisse séparateur 1 est réalisée de préférence dans un matériau ductile, tel que de l'aluminium permettant une extrusion facile.The separator smooth 1 is preferably made of a ductile material, such as aluminum allowing easy extrusion.

Selon une caractéristique essentielle de l'invention, la lisse séparateur 1 est constituée de l'assemblage d'un premier profilé 2 et d'un second profilé 3, chacun des profilés comportant un ensemble de maintien 7,7', le second profilé 3 étant solidarisé au premier profilé 2 par des moyens d'encliquetage d'une manière telle qu'après rotation du second profilé 3 autour d'un axe A longitudinal parallèle à la direction longitudinale du premier profilé 2 les grandes ailes 7a,7'a convergent l'une vers l' autre et viennent en contact. Par tolérance d'usinage, on admettra que l'écartement de leurs extrémités soit de l'ordre de l'épaisseur de deux toiles 4 superposées.According to an essential characteristic of the invention, the separator rail 1 consists of the assembly of a first profile 2 and a second profile 3, each of the profiles having a holding assembly 7,7 ', the second profile 3 being secured to the first profile 2 by latching means in such a way that after rotation of the second profile 3 around a longitudinal axis A parallel to the longitudinal direction of the first profile 2 the large wings 7a, 7'a converge towards each other and come into contact. By machining tolerance, it will be assumed that the spacing of their ends is of the order of the thickness of two superimposed fabrics 4.

Chaque ensemble de maintien 7,7' est constitué de deux ailes 7a,7'a,7b,7'b écartées l'une de l'autre et reliées par un fond 7c,7'c, à savoir une première aile externe 7a,7'a et une seconde aile interne 7b,7'b de plus faible hauteur qui se termine par un épaulement 9 qui s'étend en direction de la première aile 7a,7'a et se termine à une distance de celle-ci apte à permettre le passage de la bordure 6, de façon que celle-ci puisse venir reposer en simple appui sur l'épaulement 9.Each retaining assembly 7, 7 'consists of two wings 7a, 7'a, 7b, 7'b spaced from one another and connected by a bottom 7c, 7'c, namely a first external wing 7a, 7'a and a second internal wing 7b, 7'b of lower height which ends in a shoulder 9 which extends in the direction of the first wing 7a, 7'a and ends at a distance from the latter capable of allowing the passage of the edge 6, so that the latter can come to rest by simply pressing on the shoulder 9.

En référence aux figures 1 et 2, on décrira une première variante de réalisation de la lisse séparateur 1 selon l'invention.With reference to Figures 1 and 2 , a first alternative embodiment of the separator beam 1 according to the invention will be described.

Selon une caractéristique importante de cette première variante, les moyens d'encliquetage comportent un logement 8f longitudinal aménagé dans le premier profilé 2, un ergot 316 en saillie sur le second profilé 3 et un troisième profilé 10 élastiquement déformable placé sur toute ou parties de la longueur dudit logement 8f, l'ergot 316 et le troisième profilé 10 coopérant de manière à retenir l'ergot 316 dans le logement 8f après rotation du second profilé 3 en direction du premier profilé 2.According to an important characteristic of this first variant, the latching means comprise a longitudinal housing 8f arranged in the first profile 2, a lug 316 projecting from the second profile 3 and a third elastically deformable profile 10 placed on all or parts of the length of said housing 8f, the lug 316 and the third profile 10 cooperating so as to retain the lug 316 in the housing 8f after rotation of the second profile 3 in the direction of the first profile 2.

Le premier profilé 2 comporte une base B reliée à l'ensemble de maintien 7 par l'intermédiaire de plaques de liaison 8a,8b,8c. La base B du premier profilé 2 est formée d'une plaque de base 5. Une première plaque de liaison 8a, dont une portion est coplanaire de la grande aile 7a, est issue vers une première extrémité de la plaque de base 5. Une seconde plaque de liaison 8b est issue sensiblement vers le milieu de la plaque 5 et du même coté. La première plaque de liaison 8a et la seconde plaque de liaison 8b sont reliées par une troisième plaque de liaison 8c qui est en contact avec l'ensemble de maintien 7.
Au niveau de l'intersection de la seconde plaque de liaison 8b et de la plaque de base 5, le premier profilé 2 comporte une goulotte 8d de section circulaire et ouverte, au centre de laquelle passe l'axe de rotation A.
La troisième plaque de liaison 8c présente une certaine épaisseur et comporte, du même coté que la goulotte 8d, un logement longitudinal 8f. Ce logement 8f présente une section en forme de rectangle surmonté d'un trapèze, et comporte à son entrée un double épaulement 8g. Du coté opposé, la troisième plaque 8c comporte un évidement longitudinal fermé, permettant des économies de matière.The first section 2 has a base B connected to the holding assembly 7 by means of connection plates 8a, 8b, 8c. The base B of the first profile 2 is formed of a base plate 5. A first connecting plate 8a, a portion of which is coplanar with the large wing 7a, comes out towards a first end of the base plate 5. A second connecting plate 8b comes substantially towards the middle of the plate 5 and on the same side. The first connection plate 8a and the second connection plate 8b are connected by a third connection plate 8c which is in contact with the holding assembly 7.
At the intersection of the second connecting plate 8b and the base plate 5, the first profile 2 has a trough 8d of circular and open section, at the center of which passes the axis of rotation A.
The third connecting plate 8c has a certain thickness and comprises, on the same side as the chute 8d, a longitudinal housing 8f. This housing 8f has a section in the shape of a rectangle surmounted by a trapezoid, and comprises at its entrance a double shoulder 8g. On the opposite side, the third plate 8c has a closed longitudinal recess, allowing savings in material.

Le second profilé 3 comporte dans le prolongement de sa grande aile 7'a une aile plane 310 qui est coplanaire. Dans sensiblement la même direction, une plaque de liaison 311 est issue, environ au milieu de la largeur, du fond 7c de l'ensemble de maintien 7 et est reliée à l'aile plane 310 par une plaque de fond 312. A proximité de l'aile plane 310, la plaque de fond 312 comporte en saillie une butée 313 longitudinale. Le dimensionnent de cette butée 313 permet de définir le débattement angulaire en rotation du second profilé 3 quand il est engagé dans le premier profilé 2, avant verrouillage. A l'intersection de la plaque de fond 312 et de la plaque de liaison 311, du coté opposé à l'ensemble de fixation 7', le second profilé 3 comporte en projection vers l'extérieur une plaque d'articulation 314 terminée par un bourrelet 315 longitudinal tubulaire. Son diamètre correspond, au jeu d'assemblage près, au diamètre interne de la goulotte 8d. Enfin, la plaque de liaison 311 supporte un ergot 316, comportant un pied 317 terminé par une tête 318. De préférence, la section de la tête présente une forme triangulaire. Cet ergot est en saillie du même coté que le bourrelet 315 et la petite aile 7'b.The second profile 3 comprises, in the extension of its large wing 7 ′, a flat wing 310 which is coplanar. In substantially the same direction, a connection plate 311 comes, approximately in the middle of the width, from the bottom 7c of the retaining assembly 7 and is connected to the planar wing 310 by a bottom plate 312. Close to the flat wing 310, the bottom plate 312 projecting from a longitudinal stop 313. The dimension of this stop 313 makes it possible to define the angular movement in rotation of the second profile 3 when it is engaged in the first profile 2, before locking. At the intersection of the bottom plate 312 and the connection plate 311, on the side opposite to the fixing assembly 7 ′, the second profile 3 has, in projection towards the outside, an articulation plate 314 terminated by a longitudinal tubular bead 315. Its diameter corresponds, apart from the assembly clearance, to the internal diameter of the chute 8d. Finally, the connection plate 311 supports a lug 316, comprising a foot 317 terminated by a head 318. Preferably, the section of the head has a triangular shape. This lug protrudes on the same side as the bead 315 and the small wing 7'b.

Le troisième profilé 10 présente une section transversale en V dont chacune des parois internes comporte un épaulement 11 en saillie et en regard l'un de l'autre. Les extrémités libres du troisième profilé 10 sont en appui sur les épaulements 8g du logement 8f. Une fois inséré transversalement à force ou par translation longitudinale dans le logement 8f du premier profilé 2, il ne peut en être extrait que par translation longitudinale.The third section 10 has a V-shaped cross section, each of the internal walls of which has a protruding shoulder 11 facing one another. The free ends of the third profile 10 are supported on the shoulders 8g of the housing 8f. Once inserted transversely by force or by longitudinal translation in the housing 8f of the first profile 2, it can only be extracted by longitudinal translation.

Le troisième profilé 10 est élastiquement déformable. Il sera avantageusement réalisé dans un matériau polymère synthétique du type polypropylène ou PVC.The third profile 10 is elastically deformable. It will advantageously be made of a synthetic polymer material of the polypropylene or PVC type.

Le verrouillage par encliquetage du deuxième profilé 3 dans le premier profilé 2 est obtenu, après insertion à force du bourrelet 315 dans la goulotte 8d et rotation autour de l'axe A du deuxième profilé 2 vers le premier profilé 3, par coopération de l'ergot 316 avec les épaulements 11 du troisième profilé 10, les extrémités libres de ce dernier étant en appui sur les épaulements 8g du logement 8f et résistant aux efforts de traction exercés transversalement par le poids et la tension de la toile 4.The snap-lock of the second profile 3 in the first profile 2 is obtained, after forced insertion of the bead 315 in the trough 8d and rotation about the axis A of the second profile 2 towards the first profile 3, by cooperation of the lug 316 with the shoulders 11 of the third profile 10, the free ends of the latter being in abutment on the shoulders 8g of the housing 8f and resistant to the tensile forces exerted transversely by the weight and the tension of the fabric 4.

En référence aux figures 3 à 6, on décrira maintenant deux autres variantes de réalisation dans lesquelles le premier profilé 2 comporte une base B reliée à l'ensemble de maintien 7 par l'intermédiaire de plaques de liaison 8a,8b dont au moins une est courbe 8b et en prolongation de la petite aile 7b, le centre du rayon de courbure appartenant à l'axe A.With reference to figures 3 to 6 , we will now describe two other alternative embodiments in which the first section 2 comprises a base B connected to the holding assembly 7 by means of connection plates 8a, 8b of which at least one is curved 8b and in extension of the small wing 7b, the center of the radius of curvature belonging to axis A.

Selon la deuxième variante d'exécution particulière représentée aux figures 3 et 4, la base B du premier profilé 2 est formée d'une plaque de base 5. Une première plaque de liaison 8a, prolongée par la grande aile 7a, est issue à une première extrémité de la plaque de base 5. Une aile de liaison 8c est issue à l'extrémité opposée et du même coté. Cette aile de liaison 8c est terminée par une goulotte 8d de section circulaire et ouverte, au centre de laquelle passe l'axe de rotation A. La plaque de liaison courbe 8b relie directement le fond 7c de l'ensemble de maintien 7 à la plaque de base 5. Entre la plaque de liaison courbe 8b et l'aile de liaison 8c, la plaque de base 5 est munie d'un ergot 21.According to the second particular variant shown in figures 3 and 4 , the base B of the first profile 2 is formed of a base plate 5. A first connection plate 8a, extended by the large wing 7a, comes from a first end of the base plate 5. A connection wing 8c comes from the opposite end and on the same side. This connecting wing 8c is terminated by a chute 8d of circular and open section, in the center of which passes the axis of rotation A. The curved connecting plate 8b directly connects the bottom 7c of the holding assembly 7 to the plate basic 5. Between the plate curved connection 8b and the connecting wing 8c, the base plate 5 is provided with a lug 21.

Le second profilé 3 comporte dans le prolongement de sa grande aile 7'a une aile coudée 31 qui est terminée par un bourrelet 32 longitudinal cylindrique. Son diamètre correspond, au jeu d'assemblage près, au diamètre interne de la goulotte 8d. Le second profilé 3 comporte une aile courbe 33, issue du fond 7'c à l'extrémité opposée à l'aile coudée 31 et en regard de cette dernière. Le centre du rayon de courbure de l'aile courbe 33 appartient à l'axe central longitudinal du bourrelet 32. L'aile courbe 33 est munie à son extrémité d'un épaulement d'engagement 34, centrifuge.The second section 3 has, in the extension of its large wing 7 ′, a bent wing 31 which is terminated by a longitudinal cylindrical bead 32. Its diameter corresponds, apart from the assembly clearance, to the internal diameter of the chute 8d. The second profile 3 comprises a curved wing 33, coming from the bottom 7'c at the end opposite to the bent wing 31 and facing the latter. The center of the radius of curvature of the curved wing 33 belongs to the longitudinal central axis of the bead 32. The curved wing 33 is provided at its end with an engagement shoulder 34, centrifugal.

Une fois le bourrelet 32 inséré dans la goulotte 8d, tous les centres des rayons de courbures appartiennent à l'axe A.Once the bead 32 has been inserted into the trough 8d, all the centers of the radii of curvature belong to the axis A.

Le verrouillage par encliquetage du deuxième profilé 3 dans le premier profilé 2 est obtenu après rotation autour de l'axe A par coopération de l'ergot 21 et de l'épaulement d'engagement 34. Cette rotation peut être amorcée par appui avec un outil à main avec une extrémité plate, tel qu'une spatule, sur un méplat 35 du deuxième profilé 3 qui est aménagé dans le fond 7'c à coté de l'aile interne 7'b.The snap-lock of the second profile 3 in the first profile 2 is obtained after rotation about the axis A by cooperation of the lug 21 and the engagement shoulder 34. This rotation can be initiated by pressing with a tool hand with a flat end, such as a spatula, on a flat 35 of the second profile 3 which is arranged in the bottom 7'c next to the inner wing 7'b.

Selon la troisième variante d'exécution particulière représentée aux figures 5 et 6, la base B du premier profilé 2 est formée d'une plaque de base 5. A une première extrémité de celle-ci, une première plaque de liaison 8a prolongée par la grande aile 7a est issue. A l'extrémité opposée et du même coté, une aile de liaison 8c terminée par un épaulement d'engagement 8e est issue.According to the third particular variant shown in Figures 5 and 6 , the base B of the first profile 2 is formed of a base plate 5. At a first end thereof, a first connecting plate 8a extended by the large wing 7a is issued. At the opposite end and on the same side, a connecting wing 8c terminated by an engagement shoulder 8e is issued.

La plaque courbe 8b est creusée d'une rainure 8d courbe dont une paroi est en prolongation de la petite aile 7b et l'autre paroi parallèle est ouverte à sa base et munie d'un épaulement d'engagement 8e en regard de celui de l'aile de liaison 8c. Les centres des rayons de courbures appartiennent à l'axe A qui est extérieur à la lisse séparateur 1.The curved plate 8b is hollowed out with a curved groove 8d, one wall of which is an extension of the small wing 7b and the other parallel wall is open at its base and provided with an engagement shoulder 8e opposite that of the connecting wing 8c. The centers of the radii of curvature belong to the axis A which is outside the separator beam 1.

Le second profilé 3 comporte, dans le prolongement de sa petite aile 7'b, une aile courbe 33 dont les dimensions correspondent, au jeu d'assemblage près, à celles de la rainure 8d. Une fois assemblé avec le premier profilé 2, le centre du rayon de courbure de l'aile courbe 33 appartient à l'axe A. Le second profilé 3 comporte deux languettes 36 munies de tétons, issues perpendiculairement du fond 7'c du coté opposé à la grande et petite aile 7'a,7'b, venant coopérer avec les épaulements d'engagement 8e du premier profilé 2 pour solidariser les profilés 2,3 ensemble par encliquetage.The second profile 3 comprises, in the extension of its small wing 7′b, a curved wing 33 whose dimensions correspond, apart from the assembly clearance, to those of the groove 8d. Once assembled with the first profile 2, the center of the radius of curvature of the curved wing 33 belongs to the axis A. The second profile 3 has two tongues 36 provided with pins, coming perpendicularly from the bottom 7'c on the opposite side to the large and small wing 7'a, 7'b, coming to cooperate with the engagement shoulders 8e of the first section 2 to secure the sections 2,3 together by snap-fastening.
