Description

Domaine techniqueTechnical area

La présente invention concerne un dispositif de montage réglable d'un spot destiné à équiper un faux plafond constitué d'un matériau souple tendu, tel que par exemple une nappe en matière synthétique ou en tissu pour masquer un vrai plafond sous-jacent.The present invention relates to an adjustable mounting device of a spot for equipping a false ceiling made of a stretched flexible material, such as for example a sheet of synthetic material or fabric to hide a real underlying ceiling.

Technique antérieurePrior art

L'utilisation de plafonds tendus en polychlorure de vinyle (PVC) notamment, est de plus en plus répandue dans la construction ou la rénovation de bâtiments. Constitués d'une nappe souple en matière synthétique, les plafonds tendus permettent d'abaisser le niveau, notamment dans les bâtiments anciens à plafonds élevés. Le plafond reçoit en général les organes d'éclairage constitués principalement par des spots. Ces derniers doivent être fixés sur le "vrai" plafond et leur face inférieure doit être positionnée au niveau du plafond tendu. Il est impératif de pouvoir aligner les spots entre eux ainsi que par rapport à la face visible du plafond tendu. La plupart du temps, ces différents alignements ne peuvent être efficacement obtenus dans le bâtiment, en raison de la nature du support de spot. Toute fixation doit avoir une possibilité de réglage pour permettre un alignement parfait par rapport à la face visible du plafond tendu. De ce fait, il est nécessaire de fixer le spot sur un support, mis en place préalablement à la pose du faux plafond, pour permettre un premier réglage de l'alignement. Ce support doit évidemment rester accessible lorsque le faux plafond est posé pour permettre un réglage précis et final de l'alignement, le seul accès disponible pour ces différents réglages étant constitué par un trou pratiqué dans le plafond tendu à l'emplacement de ce spot.The use of stretched ceilings made of polyvinyl chloride (PVC) in particular, is increasingly common in the construction or renovation of buildings. Composed of a flexible sheet of synthetic material, stretch ceilings allow to lower the level, especially in older buildings with high ceilings. The ceiling usually receives lighting components consisting mainly of spots. These must be fixed to the "true" ceiling and their underside must be positioned at the level of the stretched ceiling. It is imperative to be able to align the spots between them as well as with respect to the visible face of the stretched ceiling. Most of the time, these different alignments can not be effectively achieved in the building, due to the nature of the spot support. Any fastener must have a possibility of adjustment to allow a perfect alignment with respect to the visible face of the stretched ceiling. Therefore, it is necessary to fix the spot on a support, put in place prior to the installation of the false ceiling, to allow a first adjustment of the alignment. This support must of course remain accessible when the false ceiling is placed to allow a precise and final adjustment of the alignment, the only access available for these different settings being a hole in the ceiling stretched at the location of this spot.

A cet égard, on connaît déjà un dispositif de montage réglable d'un spot tel que celui décrit par la demande de brevet FR 2 678 354 déposée au nom de la demanderesse. Ce dispositif de montage réglable d'un spot comprend un premier étrier en U fixé au vrai plafond ou sur un support adéquat, un deuxième étrier en U inversé fixé au premier au moyen de vis de serrage engagées dans des fentes oblongues ménagées dans les branches latérales d'au moins un des deux étriers, le deuxième étrier étant réglable en hauteur par rapport au premier étrier et pivotant par rapport à ce dernier autour d'un axe passant par les deux vis de serrage, et un support pour porter ledit spot ; ce dispositif de montage est remarquable en ce que ledit support comprend un troisième étrier en U rendu solidaire du deuxième étrier au moyen d'un boulon de blocage et un berceau coulissant entre les branches latérales dudit troisième étrier et réglable en hauteur par rapport à ce dernier.In this respect, an adjustable mounting device of a spot such as that described by the patent application is already known. FR 2 678 354 filed in the name of the plaintiff. This adjustable mounting device of a spot comprises a first U-shaped bracket fixed to the true ceiling or on a suitable support, a second inverted U-shaped bracket fixed to the first by means of clamping screws engaged in oblong slots formed in the lateral branches. at least one of the two stirrups, the second stirrup being adjustable in height relative to the first stirrup and pivotable relative to the latter about an axis passing through the two clamping screws, and a support for carrying said spot; this mounting device is remarkable in that said support comprises a third U-shaped stirrup secured to the second stirrup by means of a locking bolt and a cradle sliding between the lateral branches of said third stirrup and adjustable in height relative thereto .

Ce dispositif de montage réglable d'un spot est certes simple, peu encombrant, léger, incombustible et agencé pour être ajusté avant et après la pose du faux plafond. Toutefois, ce dispositif ne permet pas d'orienter facilement le spot dans les trois directions de sorte à placer le spot parfaitement dans le plan de la face visible du faux plafond afin d'éviter des défauts d'aspect de type creux ou vagues particulièrement inesthétiques notamment pour un faux plafond en toile PVC brillante. Par ailleurs, le seul accès disponible étant constitué par l'orifice pratiqué dans le plafond tendu à l'emplacement de ce spot, il n'est pas évident de régler l'alignement dudit spot notamment par rapport à la face visible du faux plafond compte tenu des dimensions dudit orifice. Le document DE9004427U1 montre un dispositif de montage d'un spot dans un faux-plafond selon le préambule de la revendication 1. Il ne permet pas non plus d'orienter facilement le spot dans les trois dimensions.This adjustable mounting device of a spot is certainly simple, compact, lightweight, incombustible and arranged to be adjusted before and after installation of the false ceiling. However, this device does not allow to easily orient the spot in the three directions so as to place the spot perfectly in the plane of the visible face of the false ceiling to avoid defects of appearance type hollow or particularly unsightly waves especially for a false ceiling in shiny PVC fabric. Moreover, the only available access being constituted by the hole made in the ceiling stretched at the location of this spot, it is not obvious to adjust the alignment of said spot especially with respect to the visible face of the false ceiling account given the dimensions of said orifice. The document DE9004427U1 shows a device for mounting a spot in a false ceiling according to the preamble of claim 1. It also does not allow to easily orient the spot in three dimensions.

Exposé de l'inventionPresentation of the invention

En outre, ce dispositif permet d'orienter facilement et parfaitement le spot par rapport à la face visible de la fausse paroi afin d'éviter des défauts d'aspect.The purpose of the present invention is therefore to overcome the aforementioned drawbacks and to propose an adjustable mounting device of an economical spot, easy and quick to implement, not requiring special tools or prior training and intended for equip a false ceiling made of stretched flexible material.

Meilleure manière de réaliser l'invention techniqueBest way to realize the technical invention

En référence aux figures 1 et 2, le dispositif de montage 1 réglable d'un spot 2 destiné à équiper une fausse paroi 3 comprend d'une part un cadre périphérique fixé aux murs ou au plafond d'un local 4 et d'autre part, une nappe extensible 5 tendue à l'intérieur de ce cadre, cette nappe extensible 5 est le plus souvent constituée par une toile de matériaux polymères tels que par exemple du polychlorure de vinyle (PVC). Cette fausse paroi 3 est principalement du type faux plafond et destinée à masquer le "vrai" plafond 6 du local 4. Toutefois, le dispositif de montage 1 peut évidemment être utilisé pour une fausse paroi 3 du type faux mur.With reference to Figures 1 and 2 , the adjustable mounting device 1 of a spot 2 intended to equip a false wall 3 comprises on the one hand a peripheral frame fixed to the walls or the ceiling of a room 4 and on the other hand, an extensible sheet 5 stretched to inside this frame, this extensible sheet 5 is most often constituted by a fabric of polymeric materials such as for example polyvinyl chloride (PVC). This false wall 3 is mainly false ceiling type and intended to hide the "true" ceiling 6 of the room 4. However, the mounting device 1 can obviously be used for a false wall 3 of the false wall type.

Ledit dispositif de montage 1 réglable de spot 2 comprend une embase 7 agencée pour être solidarisée au plafond 6 du local 4, au moins un support 8, un berceau 9 fixé sur ledit support 8 et apte à recevoir ledit spot 2, au moins trois organes de réglage 10 décalés angulairement l'un par rapport à l'autre chacun reliant l'embase 7 au support 8 et permettant de rapprocher ou d'éloigner l'ensemble (support 8-berceau 9-spot 2) de l'embase 7 au moins le long de l'axe longitudinal du dispositif de montage 1.Said mounting device 1 adjustable spot 2 comprises a base 7 arranged to be secured to the ceiling 6 of the room 4, at least one support 8, a cradle 9 fixed on said support 8 and adapted to receive said spot 2, at least three bodies each angularly offset relative to the other each connecting the base 7 to the support 8 and for moving the assembly (support 8-cradle 9-spot 2) closer to or away from the base 7 less along the longitudinal axis of the mounting device 1.

Le support 8 comprend trois éléments 80 indépendants chacun étant associé à l'un des organes de réglage 10. Les ensembles (éléments 80-organes de réglage 10) ainsi constitués sont avantageusement décalés angulairement autour de l'axe longitudinal du dispositif de montage 1 de 120 degrés l'un par rapport à l'autre. Cette configuration permet une liaison mécanique isostatique entre l'embase 7 et l'ensemble (support 8-berceau 9) et un réglage en position dudit ensemble (support 8-berceau 9) dans les trois dimensions par rapport à ladite embase 7 et donc par rapport au plafond 6 du local 4.The support 8 comprises three independent elements 80 each being associated with one of the adjusting members 10. The assemblies (elements 80-regulating members 10) thus formed are advantageously angularly offset around the longitudinal axis of the mounting device 1 of FIG. 120 degrees relative to each other. This configuration allows an isostatic mechanical connection between the base 7 and the assembly (support 8-cradle 9) and a positional adjustment of said assembly (support 8-cradle 9) in the three dimensions relative to said base 7 and therefore by compared to ceiling 6 of local 4.

Ladite embase 7 comprend une base 71 avantageusement en forme générale de Y dont chacune des branches 72 est pourvue à son extrémité libre d'un rebord 73 en forme globale de L dont une première aile 731 s'étend vers le bas perpendiculairement de ladite extrémité libre de la branche 72 en direction du support 8 et une deuxième aile 732 s'étend perpendiculairement de l'extrémité libre de la première aile 731 en direction de l'intérieur de l'embase 7 de sorte que l'extrémité de chaque branche 72 soit en forme générale de C. En outre, chaque deuxième aile 732 est pourvue d'un orifice 74 apte à coopérer avec l'organe de réglage 10 associé, ledit orifice 74 étant avantageusement un taraudage. Ladite embase 7 est destinée à être solidarisée au plafond 6 du local 4 au moyen par exemple d'au moins une vis non représentée qui est engagée à travers une fente oblongue 75 ménagée dans la base 71 de ladite embase 7, ladite base 71 étant avantageusement en contact avec ledit plafond 6.Said base 7 comprises a base 71 advantageously generally Y-shaped, each of the branches 72 is provided at its free end with a rim 73 in the overall shape of L, a first flange 731 extends downward perpendicular to said free end of the branch 72 towards the support 8 and a second flange 732 extends perpendicularly from the free end of the first flange 731 towards the inside of the base 7 so that the end of each branch 72 is in general shape of C. In addition, each second wing 732 is provided with an orifice 74 adapted to cooperate with the associated adjusting member 10, said orifice 74 being advantageously a tapping. Said base 7 is intended to be secured to the ceiling 6 of the room 4 by means for example of at least one not shown screw which is engaged through an oblong slot 75 formed in the base 71 of said base 7, said base 71 being advantageously in contact with said ceiling 6.

Ledit dispositif de montage 1 comprend en outre un support 8 comprenant trois éléments 80 indépendants en forme générale de Z, comportant une âme 81 avantageusement perpendiculaire à la deuxième aile 732 de l'embase 7, une aile interne 82 issue de l'extrémité libre de ladite âme 81 située du coté de ladite deuxième aile 732 s'étendant sensiblement parallèlement à cette dernière vers l'intérieur dudit dispositif de montage 1, et une aile externe 83 issue de l'autre extrémité libre de ladite âme 81 et s'étendant sensiblement parallèlement à ladite deuxième aile 732 vers l'extérieur dudit dispositif de montage 1. Ladite aile interne 82 de chaque élément 80 est pourvue d'un orifice 84 apte à coopérer avec l'organe de réglage 10 associé et disposé sensiblement en vis-à-vis de l'orifice 74 associé de l'embase 7. Ladite aile externe 83 permet la fixation de l'élément 80 sur le berceau 9 par tout moyen approprié tel que, par exemple, le vissage ou encore le collage.Said mounting device 1 further comprises a support 8 comprising three independent elements 80 in the general Z-shape, comprising a core 81 advantageously perpendicular to the second flange 732 of the base 7, an inner flange 82 issuing from the free end of FIG. said core 81 located on the side of said second flange 732 extending substantially parallel to the latter towards the inside of said mounting device 1, and an outer flange 83 issuing from the other free end of said core 81 and extending substantially parallel to said second flange 732 to the outside of said mounting device 1. Said inner flange 82 of each element 80 is provided with an orifice 84 adapted to cooperate with the associated adjusting member 10 and arranged substantially vis-à- screw of the associated orifice 74 of the base 7. Said outer wing 83 allows the attachment of the element 80 on the cradle 9 by any suitable means such as, for example, screwing or gluing.

On comprend bien que les trois éléments 80 du support 8 pourront être reliés entre eux de sorte à ne former qu'une seule couronne ayant une section transversale en forme d'Oméga pourvue de trois orifices 84 apte chacun à coopérer avec l'organe de réglage 10 associé, sans sortir du cadre de la présente invention. Toutefois, on comprend bien que pour des raisons essentiellement économiques, il est préférable d'avoir un support 8 comprenant trois éléments 80 indépendants en forme de Z.It is well understood that the three elements 80 of the support 8 may be connected together so as to form a single crown having an Omega-shaped cross section provided with three orifices 84 each adapted to cooperate with the adjustment member 10 without departing from the scope of the present invention. However, it is understood that for essentially economic reasons, it is preferable to have a support 8 comprising three independent elements 80 Z-shaped.

On comprend bien que, pour des raisons de poids, l'embase 7 et le support 8 sont avantageusement réalisés à partir de tôles en alliage léger de type aluminium de faible épaisseur de l'ordre de quelques millimètres, dans lesquelles il est peu évident de réaliser un taraudage dans de bonnes conditions. Par conséquent, l'orifice 74 du type taraudage est de préférence remplacé par un trou lisse associé à un écrou 76 fixé sur la deuxième aile 732 de l'embase 7 à l'intérieur de cette dernière au droit dudit orifice 74, sans sortir du cadre de la présente invention. Ledit écrou 76 est fixé sur la deuxième aile 732 de l'embase 7 par tout moyen approprié tel que, par exemple, le soudage, le sertissage ou encore le collage.It is well understood that, for reasons of weight, the base 7 and the support 8 are advantageously made from sheets of aluminum-type lightweight alloy of small thickness of the order of a few millimeters, in which it is not very obvious. perform tapping in good conditions. Consequently, the orifice 74 of the tapping type is preferably replaced by a smooth hole associated with a nut 76 fixed on the second flange 732 of the base 7 inside the latter to the right of said orifice 74, without leaving the of the present invention. Said nut 76 is fixed on the second flange 732 of the base 7 by any appropriate means such as, for example, welding, crimping or gluing.

L'embase 7 est reliée à chaque élément 80 du support 8 par un organe de réglage 10 apte à coopérer simultanément aux orifices 74, 84 respectifs de l'embase 7 et de chaque élément 80. Chaque organe de réglage 10 comporte une tige filetée 101, un premier écrou 102 et un deuxième écrou 103. La tige filetée 101 passe au travers de l'orifice 84 de l'élément 80 associé. Lesdits premier et deuxième écrous 102, 103 sont fixés de part et d'autre de l'aile interne 82 de l'élément 80 de manière à solidariser chaque tige filetée 101 à l'élément 80 associé du support 8 par une liaison mécanique du type "pivot".The base 7 is connected to each element 80 of the support 8 by an adjusting member 10 able to cooperate simultaneously with the respective orifices 74, 84 of the base 7 and of each element 80. Each adjustment member 10 comprises a threaded rod 101 , a first nut 102 and a second nut 103. The threaded rod 101 passes through the orifice 84 of the associated element 80. Said first and second nuts 102, 103 are fixed on either side of the inner wing 82 of the element 80 so as to secure each threaded rod 101 to the associated element 80 of the support 8 by a mechanical connection of the "pivot" type.

Le terme liaison mécanique désigne ici une mise en relation de deux pièces par contact physique permettant de les rendre partiellement ou totalement solidaires (en supprimant ou non l'un des six degrés de liberté : trois translations, trois rotations, d'une pièce par rapport à l'autre) et en contribuant à la transmission éventuelle d'un effort entre les deux pièces. Par ailleurs, une liaison mécanique de type "pivot" est telle que le seul degré de liberté autorisé entre les pièces est un mouvement de rotation.The term "mechanical connection" here designates a connection between two pieces by physical contact making it possible to partially or totally make them integral (by eliminating or not one of the six degrees of freedom: three translations, three rotations, of one piece compared to to the other) and contributing to the possible transmission of an effort between the two pieces. Furthermore, a mechanical connection type "pivot" is such that the only degree of freedom allowed between the parts is a rotational movement.

Dans le cas présent, la liaison mécanique de type "pivot" entre chaque tige filetée 101 et le support 8 n'autorise que la rotation de ladite tige filetée 101 autour de son axe longitudinal dans l'orifice 84 de l'élément 80 associé du support 8.In the present case, the "pivot" type mechanical connection between each threaded rod 101 and the support 8 authorizes only the rotation of said threaded rod 101 about its longitudinal axis in the orifice 84 of the associated element 80. support 8.

Lesdits premier et deuxième écrous 102, 103 sont fixés sur la tige filetée 101 par tout moyen approprié tel que, par exemple, le soudage ou encore collage.Said first and second nuts 102, 103 are fixed on the threaded rod 101 by any appropriate means such as, for example, welding or gluing.

Pour permettre sa manipulation, la tige filetée est pourvue de préférence d'une empreinte hexagonale à son extrémité libre situé du coté du support 8. En effet, après avoir solidarisé chaque tige filetée 101 au support 8 associé à l'aide des premier et deuxième écrous 102, 103, chaque tige filetée 101 est engagée dans l'orifice 74 associé de l'embase 7 puis vissée plus ou moins dans l'écrou 76 de sorte à rapprocher plus ou moins le support 8 de ladite embase 7. On comprend bien que le fait d'avoir trois organes de réglage 10 indépendants décalés angulairement de 120 degrés l'un par rapport à l'autre permet un réglage de la position du support 8, du berceau 9 et donc du spot 2 selon les trois dimensions.To allow its manipulation, the threaded rod is preferably provided with a hexagonal recess at its free end located on the side of the support 8. In fact, after having secured each threaded rod 101 to the associated support 8 using the first and second nuts 102, 103, each threaded rod 101 is engaged in the associated orifice 74 of the base 7 and then screwed more or less into the nut 76 so as to bring more or less the support 8 of said base 7. It is understood well that the fact of having three independent adjustment members 10 angularly offset by 120 degrees relative to each other allows adjustment of the position of the support 8, the cradle 9 and therefore the spot 2 in three dimensions.

Le berceau 9 est avantageusement un anneau réalisé en matière isolante telle que par exemple du polychlorure de vinyle (PVC) expansé coextrudé. Ce berceau 9 est fixé sur les supports 8 et est tel que ses dimensions intérieures autorisent l'accès aux tiges filetées 101 des organes de réglage 10 même lorsque ledit berceau 9 est fixé sur le support 8. En outre, le berceau 9 est apte à recevoir la nappe extensible 5 et le spot 2.The cradle 9 is advantageously a ring made of insulating material such as, for example, coextruded expanded polyvinyl chloride (PVC). This cradle 9 is fixed on the supports 8 and is such that its internal dimensions allow access to the threaded rods 101 of the adjustment members 10 even when said cradle 9 is fixed on the support 8. In addition, the cradle 9 is adapted to receive extensible web 5 and spot 2.

Ledit spot 2 est monté dans le berceau 9 au moyen d'un dispositif de fixation rapide de type clips. On pourra intercaler entre le spot 2 et la nappe extensible 5 au moins une rondelle (non représentée) thermiquement et électriquement isolante. Le spot 2 peut être un spot disponible dans le commerce pourvu d'un support, et d'une bague intérieure pivotante recevant l'ampoule.Said spot 2 is mounted in the cradle 9 by means of a quick fastener type clips. It is possible to interpose between the spot 2 and the extensible sheet 5 at least one washer (not shown) thermally and electrically insulating. The spot 2 may be a commercially available spot provided with a support, and a pivoting inner ring receiving the bulb.

Pour régler l'installation du spot 2 avec le dispositif de montage 1 selon l'invention, on fixe tout d'abord l'embase 7 sur le plafond 6 du local 4. Ensuite, on monte pivotante l'une des extrémités de chaque organe de réglage 10 sur le support 8, ledit support 8 ayant été de préférence au préalable fixé sur le berceau 9. Puis, on engage l'extrémité libre de chaque organe de réglage 10 dans l'embase 7 et l'on visse plus ou moins la vis 101 de chaque organe de réglage 10 dans le premier écrou 102 fixé sur l'embase 7 pour rapprocher plus ou moins le berceau 9 de l'embase 7 et donc du plafond 6. Ensuite, la nappe extensible 5 de la fausse paroi 3 est mise en place devant le dispositif de montage 1 et ajustée sur le berceau 9. Avant la mise en place du spot 2 dans le berceau 9, le réglage de la position du spot 2 peut être affiné dans les trois directions en agissant sur la vis 101 de chaque organe de réglage 10 de sorte à placer le berceau 9 parfaitement dans le plan du faux plafond 3 afin d'éviter des défauts d'aspect de type creux ou vagues. Enfin, une fois le réglage terminé, le spot 2 est raccordé électriquement et mis en place dans le berceau 9.In order to adjust the installation of the spot 2 with the mounting device 1 according to the invention, the base 7 is first fixed on the ceiling 6 of the room 4. Then, one of the ends of each member is pivotally mounted. 10 on the support 8, said support 8 having preferably been previously fixed on the cradle 9. Then, the free end of each adjustment member 10 is engaged in the base 7 and the screw is screwed more or less the screw 101 of each adjusting member 10 in the first nut 102 fixed on the base 7 to more or less bring closer the cradle 9 of the base 7 and therefore the ceiling 6. Then the extensible web 5 of the false wall 3 is placed in front of the mounting device 1 and adjusted on the cradle 9. Before placing the spot 2 in the cradle 9, the adjustment of the position of the spot 2 can be refined in three directions by acting on the screw 101 of each adjustment member 10 so as to place the cradle 9 perfectly in the plane false ceiling 3 to avoid hollow or vague type of appearance defects. Finally, once the adjustment is complete, the spot 2 is connected electrically and set up in the cradle 9.

Description d'autres modes de réalisationDescription of other embodiments

En référence à la figure 3, dans un second mode de réalisation, la vis de fixation, engagée à travers la fente oblongue 75 ménagée dans la base 71 de l'embase 7 et destinée à solidariser cette dernière au plafond 6 du local 4, est remplacé par un organe de fixation réglable 20 semblable à l'organe de réglage 10 précédemment décrit. Ainsi, cet organe de fixation réglable 20 comporte une tige filetée 201 agencée pour être fixée dans le plafond 6 du local 4, un premier écrou 202 et un deuxième écrou 203 fixés sur la tige filetée 201 qui passe au travers de la fente oblongue 75 ménagée dans la base 71 de l'embase 7. Lesdits deuxième et troisième écrous 202, 203 sont fixés de part et d'autre de ladite base 71 afin de bloquer l'embase 7 le long de la tige filetée 201 à une position déterminée. Cette configuration permet un réglage supplémentaire plus important de la position du berceau 9 par rapport au plafond 6 du local 4.With reference to the figure 3 in a second embodiment, the fixing screw, engaged through the oblong slot 75 formed in the base 71 of the base 7 and intended to secure the latter to the ceiling 6 of the room 4, is replaced by a fixing member adjustable 20 similar to the regulator 10 previously described. Thus, this adjustable fastener 20 comprises a threaded rod 201 arranged to be fixed in the ceiling 6 of the room 4, a first nut 202 and a second nut 203 fixed on the threaded rod 201 which passes through the oblong slot 75 arranged in the base 71 of the base 7. Said second and third nuts 202, 203 are fixed on either side of said base 71 to block the base 7 along the threaded rod 201 at a specific position. This configuration allows a greater additional adjustment of the position of the cradle 9 relative to the ceiling 6 of the room 4.

Selon un autre mode de réalisation non représenté, chaque organe de réglage 10 est couplé à un ressort hélicoïdal disposé autour de la tige filetée 101 entre l'embase 7 et le support 8 ou à un compas comportant une branche interne et une branche externe articulées entre elles à l'une de leurs extrémités autour d'un premier axe non représenté sensiblement perpendiculaire à l'axe longitudinal 10 du dispositif de montage 1 et articulées à leur extrémité libre respectivement à l'embase 7 autour d'un deuxième axe et au support 8 autour d'un troisième axe, les deuxième et troisième axes étant sensiblement parallèles audit premier axe. On désigne ici par branche interne la branche du compas située du coté du plafond 6 et par branche externe la branche du compas située du coté de la nappe extensible 5. Ces équipements supplémentaires qui assurent un blocage en position plus efficace demeurent toutefois difficiles à mettre en oeuvre.According to another embodiment not shown, each adjusting member 10 is coupled to a helical spring disposed around the threaded rod 101 between the base 7 and the support 8 or to a compass comprising an inner branch and an outer branch hinged between they at one of their ends around a first axis not shown substantially perpendicular to the longitudinal axis 10 of the mounting device 1 and articulated at their free end respectively to the base 7 about a second axis and the support 8 around a third axis, the second and third axes being substantially parallel to said first axis. Here the internal branch is the branch of the compass located on the side of the ceiling 6 and the outer branch of the compass on the side of the the extensible web 5. These additional equipment that provide blocking in a more effective position, however, remain difficult to implement.

En référence aux figures 4 et 5, dans un autre mode de réalisation, le dispositif de montage 1 comporte une embase 7 comprenant une base en forme générale de T dont chacune des branches 72 est pourvue à son extrémité libre d'un orifice apte à coopérer avec l'organe de réglage 10 associé. Cette embase 7 comporte deux branches 72 diamétralement opposées par rapport à l'axe longitudinal du dispositif de montage 1 et est solidarisée au plafond du local par un organe de fixation réglable 30. Ce dernier comprend tout d'abord un premier étrier 31 en forme de U destiné à être fixé au vrai plafond au moyen d'au moins une vis qui est engagée à travers une fente oblongue 311. Cet étrier 31 se compose de deux branches latérales 312 et 313 et d'une partie transversale 314 dans laquelle est ménagée ladite fente oblongue 311. Les branches latérales sont avantageusement équipées de deux fentes oblongues axiales 312' et 313'.With reference to Figures 4 and 5 , in another embodiment, the mounting device 1 comprises a base 7 comprising a generally T-shaped base, each of the branches 72 is provided at its free end with an orifice adapted to cooperate with the adjustment member 10 associated. This base 7 comprises two branches 72 diametrically opposite with respect to the longitudinal axis of the mounting device 1 and is secured to the ceiling of the room by an adjustable fixing member 30. The latter comprises firstly a first stirrup 31 in the form of U intended to be fixed to the true ceiling by means of at least one screw which is engaged through an oblong slot 311. This stirrup 31 consists of two lateral branches 312 and 313 and a transverse portion 314 in which is provided said oblong slot 311. The lateral branches are advantageously equipped with two axial oblong slots 312 'and 313'.

L'organe de fixation réglable 30 comporte en outre deux cornières 32 chacune étant fixée par sa première aile 321 sur le dessus des deux branches 72 diamétralement opposées de l'embase 7. Lesdites cornières 72 sont disposées en vis-à-vis de sorte à former un deuxième étrier en forme de U inversé, c'est à dire positionné dans le sens inverse par rapport au premier et fixé au premier par deux vis de serrage 33 engagées dans les fentes axiales 312' et 313' et dans la deuxième aile 322 de la cornière 32 associée. Lesdites deuxièmes ailes 322 pourront chacune être équipées, si nécessaire, d'une fente oblongue axiales. Cette configuration permet un réglage supplémentaire plus important de la position du berceau 9 par rapport au plafond du local, mais également un réglage supplémentaire autour de l'axe formé par lesdites deux vis de serrage 33.The adjustable fastening member 30 further comprises two brackets 32 each being fixed by its first flange 321 on top of the two diametrically opposite branches 72 of the base 7. Said brackets 72 are arranged vis-à-vis so as to forming a second inverted U-shaped stirrup, ie positioned in the opposite direction relative to the first and fixed to the first by two clamping screws 33 engaged in the axial slots 312 'and 313' and in the second wing 322 of the angle 32 associated. Said second wings 322 may each be equipped, if necessary, with an axial oblong slot. This configuration allows a greater additional adjustment of the position of the cradle 9 relative to the ceiling of the room, but also a setting additional around the axis formed by said two clamping screws 33.

En outre, en référence à la figure 5, le dispositif de montage 1 comprend des organes de réglage 10 comportant une tige filetée 101 solidaire de l'élément 80 associé du support 8 par une liaison mécanique du type "pivot" autour d'un axe sensiblement vertical. Chaque tige filetée 101 est apte à coopérer avec un écrou 76 solidaire de la branche 72 associée de l'embase 7.In addition, with reference to figure 5 , the mounting device 1 comprises adjusting members 10 comprising a threaded rod 101 secured to the associated element 80 of the support 8 by a mechanical connection of the "pivot" type about a substantially vertical axis. Each threaded rod 101 is able to cooperate with a nut 76 secured to the associated branch 72 of the base 7.

Par ailleurs, la tige filetée 101 est pourvue de préférence d'une empreinte à son extrémité libre situé du coté du support 8 pour permettre sa manipulation à l'aide, par exemple, d'un tournevis 35 passé à l'intérieur du berceau 9. Ainsi, on pourra aisément visser ou dévisser indépendamment chaque tige filetée 101 dans l'écrou 76 de sorte à rapprocher plus ou moins le support 8 de ladite embase 7 afin d'obtenir un réglage de la position du support 8, du berceau 9 et donc du spot 2 selon les trois dimensions.Furthermore, the threaded rod 101 is preferably provided with an imprint at its free end located on the side of the support 8 to allow its manipulation using, for example, a screwdriver 35 passed inside the cradle 9 Thus, each threaded rod 101 can be easily screwed or unscrewed independently into the nut 76 so as to move the support 8 closer to said base 7 in order to obtain an adjustment of the position of the support 8, of the cradle 9 and therefore spot 2 according to the three dimensions.

Enfin, on sait que les spots utilisés dans le dispositif de montage 1 réglable d'un spot 2, selon l'invention, sont généralement des spots basse tension et nécessitent par conséquent des transformateurs. Pour des questions de maintenance, ces transformateurs (non représentés) doivent être facilement accessibles et doivent donc être disposés à proximité du berceau 9. Toutefois, ces transformateurs ne doivent pas reposer sur la nappe extensible 5 afin de ne pas marquer ladite nappe extensible 5 voire de l'abimer en raison de leur échauffement. Pour cela, selon un dernier mode de réalisation non représenté, le berceau 9 du dispositif de montage 1 comporte un organe de fixation rapide, avantageusement de type clips, apte à coopérer avec un organe récepteur d'un support recevant le transformateur du spot 2, pour solidariser de façon amovible l'ensemble support-transformateur sur le berceau 9 avantageusement à l'extérieur dudit dispositif de montage 1 et entre la nappe extensible 5 et le plafond 6 du local 4.Finally, it is known that the spots used in the adjustable mounting device 1 of a spot 2 according to the invention are generally low voltage spots and therefore require transformers. For maintenance reasons, these transformers (not shown) must be easily accessible and must therefore be placed close to the cradle 9. However, these transformers must not rest on the extensible layer 5 so as not to mark said extensible layer 5 even to damage it because of their warming up. For this, according to a last embodiment not shown, the cradle 9 of the mounting device 1 comprises a quick fastener, advantageously clip type, adapted to cooperate with a receiving member of a support receiving the transformer of the spot 2, to detachably connect the support-transformer assembly on the cradle 9 advantageously outside said mounting device 1 and between the extensible web 5 and the ceiling 6 of the local 4.

Possibilité d'application industriellePossibility of industrial application

Le dispositif de montage 1 réglable d'un spot 2 selon l'invention est principalement destiné à être utilisé en intégration d'une fausse paroi dans tout type de local et quelque soit l'orientation de ladite fausse-paroi 3. En outre, il ressort clairement de la description que le dispositif de montage 1 selon l'invention est de construction légère et simple, et qu'il permet d'obtenir simplement et finement un réglage d'un spot 2 dans les trois dimensions.The adjustable mounting device 1 of a spot 2 according to the invention is mainly intended to be used in integration of a false wall in any type of room and whatever the orientation of said false wall 3. In addition, it It is clear from the description that the mounting device 1 according to the invention is light and simple construction, and that it allows to obtain simply and finely a setting of a spot 2 in three dimensions.

Enfin, il va de soi que les exemples de dispositif de montage 1 conformes à l'invention qui viennent d'être décrits ne sont que des illustrations particulières, en aucun cas limitatives de l'invention telle que définie par les revendications.Finally, it goes without saying that the examples of mounting device 1 according to the invention which have just been described are only particular illustrations, in no way limiting the invention as defined by the claims.
