Description

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, ce dispositif comprenant un premier étrier en U inversé fixé au vrai plafond ou sur un support adéquat au moyen d'au moins une vis de serrage engagée dans au moins une fente oblongue ménagée dans sa partie transversale, ce premier étrier étant réglable dans un plan horizontal par rapport à ladite vis de serrage, un deuxième étrier en U 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 un spot.The present invention relates to an adjustable mounting device for a spotlight intended to equip a false ceiling made of a stretched flexible material, such as for example a ply of synthetic material or fabric to mask a real underlying ceiling, this device comprising a first inverted U-shaped bracket fixed to the real ceiling or on a suitable support by means of at least one clamping screw engaged in at least one oblong slot formed in its transverse part, this first bracket being adjustable in a horizontal plane relative to to said clamping screw, a second U-shaped bracket fixed to the first by means of clamping screws engaged in oblong slots formed in the lateral branches of at least one of the two brackets, the second bracket being adjustable in height relative to the first bracket and pivoting with respect to the latter about an axis passing through the two clamping screws, and a support for carrying a spot.

L'utilisation de plafonds tendus en PVC est de plus en plus répandue dans la construction 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 spots doivent être fixés sur le vrai plafond et leur face inférieure doit être positionnée au niveau du plafond tendu. Il est impératif d'une part de pouvoir aligner les spots par rapport au plafond tendu et d'autre part de les aligner entre-eux pour qu'ils soient bien en ligne. Ces différents alignements ne peuvent se faire efficacement dans le bâtiment compte tenu de la nature du support de spot. Toute fixation doit avoir une possibilité de réglage pour permettre un alignement parfait. De ce fait, il est nécessaire de fixer le spot sur un support, qui a été mis en place préalablement à la pose du faux plafond et permettant un premier réglage de l'alignement, ce support devant rester accessible lorsque le faux plafond est posé pour permettre un réglage précis et final de l'alignement, le seul accès disponible étant constitué par le trou pratiqué dans le plafond tendu à l'emplacement de ce spot.The use of PVC stretch ceilings is more and more widespread in the construction of buildings. Made of a flexible synthetic material, stretch ceilings allow the level to be lowered, especially in old buildings with high ceilings. The ceiling generally receives the lighting elements mainly constituted by spotlights. These spots must be fixed on the real ceiling and their lower face must be positioned at the level of the stretch ceiling. It is imperative on the one hand to be able to align the spots relative to the stretch ceiling and on the other hand to align them between them so that they are well in line. These different alignments cannot be done effectively in the building, given the nature of the spot support. Any fixing must have a possibility of adjustment to allow a perfect alignment. Therefore, it is necessary to fix the spot on a support, which was put in place prior to the installation of the false ceiling and allowing a first adjustment of the alignment, this support having to remain accessible when the false ceiling is installed for allow precise and final adjustment of the alignment, the only available access being the hole in the stretch ceiling at the location of this spot.

Le brevet FR-2 587 447, du même titulaire, décrit une chaise à spot ne permettant que le positionnement du spot suivant un axe vertical, le réglage pouvant être difficilement effectué après la pose du faux plafond.Patent FR-2 587 447, by the same holder, describes a spot chair only allowing the positioning of the spot along a vertical axis, the adjustment being difficult to make after the false ceiling has been installed.

La demande de brevet français FR-A-2 647 139 décrit un support de spot dans lequel la cloche recevant ledit spot est montée à l'extrémité d'une tige de fixation, l'autre extrémité est fixée au vrai plafond. Ce moyen de fixation est très instable et ne permet pas de garantir l'immobilisation du support après le réglage de son positionnement par rapport au faux plafond. La cloche est prévue d'être réglable en hauteur par coulissement au moyen d'un étrier dont les branches latérales s'appuient par effet ressort contre la paroi intérieure de la cloche. Ce moyen de réglage est imprécis et se dérègle dans le temps.French patent application FR-A-2 647 139 describes a spot support in which the bell receiving said spot is mounted at the end of a fixing rod, the other end is fixed to the real ceiling. This fixing means is very unstable and does not guarantee the immobilization of the support after adjusting its positioning relative to the false ceiling. The bell is designed to be adjustable in height by sliding by means of a stirrup, the lateral branches of which bear by spring effect against the internal wall of the bell. This means of adjustment is imprecise and is adjusted over time.

La première 35 est par exemple réalisée en Klingérite® et la deuxième 36 est de préférence réalisée en matière synthétique rigide telle que du PVC. Le spot 32 peut être un spot disponible dans le commerce pourvu d'un support 37, et d'une bague intérieure pivotante 38 recevant l'ampoule 39.A spot 32 is mounted in the cradle 21 by means of a bayonet type fixing device comprising two pins 33 and 34 provided in the lateral branches 23 and 24. Two thermally and electrically insulating washers 35 and 36 are arranged in superposition on the annular part 26. The first 35 is for example made of Klingerite® and the second 36 is preferably made of rigid synthetic material such as PVC. The spot 32 can be a commercially available spot provided with a support 37, and a pivoting inner ring 38 receiving the bulb 39.

Dans la réalisation illustrée par la figure 3, la variante se situe au niveau de l'élément support de spot qui n'est plus un berceau 21, mais un élément appelé chaise à spot 61 fixée à un troisième étrier 53 en forme de U, au moyen de deux vis de serrage 56 engagées dans des fentes oblongues 54′ et 55′ ménagées dans des branches latérales 54 et 55 dudit étrier. Cette chaise à spot est constituée d'une plaque de base 62 dans laquelle est ménagée une ouverture centrale 63 prévue pour recevoir un spot et de deux branches latérales 64 et 65 en forme de L, fixées d'un côté sur la plaque de base 62 au moyen de deux vis 66 et 67, et de l'autre côté aux branches latérales 54 et 55, les vis de serrage passant à travers des trous 64′ et 65′.In the embodiment illustrated in FIG. 3, the variant is located at the spot support element which is no longer a cradle 21, but an element called spot chair 61 fixed to a third U-shaped stirrup 53, by means of two clamping screws 56 engaged in oblong slots 54 ′ and 55 ′ formed in lateral branches 54 and 55 of said stirrup. This spot chair consists of a base plate 62 in which is formed a central opening 63 intended to receive a spot and two lateral branches 64 and 65 in the shape of an L, fixed on one side to the base plate 62 by means of two screws 66 and 67, and on the other side to the lateral branches 54 and 55, the clamping screws passing through holes 64 ′ and 65 ′.

Lors de la mise en place du dispositif décrit précédemment, le premier étrier 1 est fixé au vrai plafond par la vis 2 après avoir été positionné par déplacement transversal selon l'axe de la fente oblongue 3 et en rotation autour de la vis 2. Le deuxième étrier 7 est ensuite monté dans le premier étrier 1 et fixé par les deux vis de serrage 8 passant au travers des fentes oblongues respectivement 4′ et 9′, et, 5′ et 10′, après avoir été réglé en hauteur selon l'axe défini par les fentes oblongues 4′ et 5′, et en rotation selon l'axe défini par les deux vis. Il est possible de remplacer les fentes oblongues 9′ et 10′ prévues dans l'étrier 7 par des trous lisses. Ces deux premiers étriers 1 et 7 permettent un premier réglage de l'alignement du support de spot avant la pose du faux plafond. Une hauteur provisoire peut être adaptée entre le vrai plafond et la base du deuxième étrier 7 formée par sa partie transversale 11, cette hauteur étant comprise entre une fois et deux fois la longueur d'une fente oblongue. Le troisième étrier 13 est ensuite fixé au deuxième étrier 7 au moyen du boulon de blocage 14 passant par l'alésage 18 et la fente oblongue 12. Il est réglable par rapport à l'étrier 7 transversalement selon l'axe de la fente oblongue 12 et en rotation autour du boulon 14. Ce boulon est de préférence du type Japy® de manière à interdir toute rotation de la vis du boulon dans la fente 12. L'écrou dudit boulon est serré par une clé à tube passant au travers de l'alésage 29 prévu dans le berceau 21. Le berceau 21 est engagé par coulissement dans le troisième étrier 13, les deux vis 27 et 28 solidaires du berceau étant vissées dans les trous taraudés 19 et 20 prévus dans l'étrier 13. En vissant et dévissant lesdites vis 27 et 28, le berceau se rapproche ou s'éloigne de l'étrier 13 selon l'axe des branches latérales coulissant l'une par rapport à l'autre guidées par leur profil complémentaire. Les vis sont actionnées par une clé à tube passant par l'emplacement du spot prévue dans le berceau 21. Les réglages en position du troisième étrier 13 et du berceau 21 étant réalisés au moyen de boulon et vis accessibles par le trou prévu dans le faux plafond pour le spot, il est possible d'ajuster au plus juste l'axe du berceau recevant le spot avec l'axe dudit trou pour qu'ils se superposent, et la hauteur dudit berceau pour que la face antérieure du spot soit au niveau du faux plafond. Le spot 32 est ensuite monté dans le berceau 21 par I'intermédiaire d'au moins deux rondelles isolantes 35 et 36, le faux plafond passant entre ces deux rondelles, et étant maintenu par les deux goupilles 33. L'ampoule 39 est montée dans la bague intérieure pivotante 38 par un circlips non représenté. Cette bague laisse un passage circulaire d'air permettant la ventilation automatique de l'ampoule. Cette ampoule 39 est alimentée par un fil électrique sortant du vrai plafond et passant soit au travers ou à côté dudit dispositif de montage réglable du spot.When the device described above is put in place, the first bracket 1 is fixed to the real ceiling by the screw 2 after having been positioned by transverse displacement along the axis of the oblong slot 3 and in rotation around the screw 2. The second bracket 7 is then mounted in the first bracket 1 and fixed by the two clamping screws 8 passing through oblong slots respectively 4 ′ and 9 ′, and, 5 ′ and 10 ′, after having been adjusted in height according to the axis defined by the oblong slots 4 ′ and 5 ′, and in rotation along the axis defined by the two screws. It is possible to replace the oblong slots 9 ′ and 10 ′ provided in the stirrup 7 with smooth holes. These first two brackets 1 and 7 allow a first adjustment of the alignment of the spot support before installing the false ceiling. A temporary height can be adapted between the real ceiling and the base of the second stirrup 7 formed by its transverse part 11, this height being between once and twice the length of an oblong slot. The third stirrup 13 is then fixed to the second stirrup 7 by means of the locking bolt 14 passing through the bore 18 and the oblong slot 12. It is adjustable relative to the stirrup 7 transversely along the axis of the oblong slot 12 and in rotation around the bolt 14. This bolt is preferably of the Japy® type so as to prevent any rotation of the bolt screw in the slot 12. The nut of said bolt is tightened by a pipe wrench passing through the bore 29 provided in the cradle 21. The cradle 21 is slidably engaged in the third stirrup 13, the two screws 27 and 28 integral with the cradle being screwed into the tapped holes 19 and 20 provided in the stirrup 13. By screwing and unscrewing said screws 27 and 28, the cradle approaches or moves away from the stirrup 13 along the axis of the lateral branches sliding relative to each other guided by their complementary profile. The screws are actuated by a pipe wrench passing through the location of the spot provided in the cradle 21. The adjustments in position of the third stirrup 13 and the cradle 21 are carried out by means of bolts and screws accessible through the hole provided in the false ceiling for the spot, it is possible to adjust as closely as possible the axis of the cradle receiving the spot with the axis of said hole so that they overlap, and the height of said cradle so that the front face of the spot is at the level from the false ceiling. The spot 32 is then mounted in the cradle 21 by I'intermediate of at least two insulating washers 35 and 36, the false ceiling passing between these two washers, and being held by the two pins 33. The bulb 39 is mounted in the pivoting inner ring 38 by a circlip not shown. This ring leaves a circular air passage allowing automatic ventilation of the bulb. This bulb 39 is powered by an electric wire leaving the real ceiling and passing either through or next to said adjustable mounting device of the spot.
