Description

Dispositif comportant un support amovible pour les luminaires et lampes encastrés dans plafond à lames suspendues.Device comprising a removable support for luminaires and lamps recessed in suspended louvre ceiling.

On connait actuellement des luminaires, bas voltage, qui s'encastrent dans les lames des plafonds par le truchement d'un support qui s'appuie sur lesdites lames par l'intermé­diaire de ressorts latéraux.Low-voltage luminaires are currently known which are fitted into the ceiling slats by means of a support which is supported on said blades by means of lateral springs.

L'inconvénient majeur de ces dispositifs réside en ce qu'il est impossible d'extraire les luminaires de leur support pour les changer par exemple.The major drawback of these devices is that it is impossible to extract the luminaires from their support to change them, for example.

En effet, ces luminaires sont placés en retrait, dans l'ouver­ture circulaire de la partie horizontale du support, ne laissant pas la possibilité de les appréhender, en conséquence les techniciens doivent obligatoirement démonter les lames du plafond se trouvant à proximité de chaque luminaire pour vérifier ou changer ces dernières par exemple. Cette contrainte entraîne une perte de temps considérable et bien souvent, à la longue, une détérioration des lames du plafond.Indeed, these luminaires are set back, in the circular opening of the horizontal part of the support, not leaving the possibility of apprehending them, consequently the technicians must obligatorily dismantle the blades of the ceiling being near each luminaire to check or change these for example. This constraint results in a considerable loss of time and very often, over time, deterioration of the ceiling planks.

Le dispositif objet de l'invention permet de remédier à ces inconvénients en ce qu'il autorise facilement et à volonté l'enlèvement d'un luminaire ou son placement dans le support et son branchement sur une douille, sans nécessité de défaire une partie du plafond suspendu.The device object of the invention overcomes these drawbacks in that it allows easily and at will the removal of a luminaire or its placement in the support and its connection to a socket, without the need to undo part of the suspended ceiling.

Le dispositif objet de la présente demande comporte une cuvette d'encastrement qui se maintient sur les lames d'un plafond ou faux-plafond avec tous moyens appropriés tels que des ressorts, pinces, vis, etc ...The device which is the subject of the present application comprises a recessing bowl which is maintained on the strips of a ceiling or false ceiling with all appropriate means such as springs, clamps, screws, etc.

Dans cette cuvette glisse par son ouverture inférieure un support de luminaire de forme cylindrique en acier ou en alliage d'aluminium ou matière plastique, etc ...In this bowl slides through its lower opening a luminaire support of cylindrical shape in steel or aluminum alloy or plastic, etc.

Ce support de luminaire a la paroi extérieure en contact avec la cuvette, qui possède des gorges sur le pourtour pour loger un joint torique en caoutchouc permettant d'immobiliser ledit support de luminaire sur la cuvette.This luminaire support has the outer wall in contact with the bowl, which has grooves on the periphery to accommodate a rubber O-ring making it possible to immobilize said luminaire support on the bowl.

Le support de luminaire peut être retiré de son logement, constitué par la cuvette d'encastrement, par le débordement périphérique situé à sa base et apparaissant sous la lame du plafond. Le luminaire peut être constitué d'une ampoule solidaire de son réflecteur ou d'une ampoule indépendante d'un réflecteur.The luminaire support can be removed from its housing, constituted by the recessing bowl, by the peripheral overflow located at its base and appearing under the ceiling strip. The luminaire may consist of a bulb integral with its reflector or of a bulb independent of a reflector.

Lors du retrait du support du luminaire, ce dernier entraîne le luminaire proprement dit ainsi que de la douille, lesquels sont maintenus ensemble par tous moyens appropriés tels qu'­avec des élastiques caoutchouc, ressorts, pinces, etc ...When removing the luminaire support, the latter drives the luminaire itself as well as the socket, which are held together by any suitable means such as with rubber bands, springs, clamps, etc.

Ce type de support amovible rendant le remplacement de la lampe plus facile peut être utilisé dans le corps d'autres appareils tels que suspension, applique, etc ...This type of removable support making the replacement of the lamp easier can be used in the body of other devices such as suspension, wall lamp, etc ...

Dans un même support ou sur un même appareil on peut placer plusieurs supports amovibles de ce type.Several removable supports of this type can be placed in the same support or on the same device.

Tel que représenté par les figures 1, 2 et 5, le dispositif comporte une cuvette 1 d'encastrement placée dans un trou préalablement confectionné dans une lame 2 du plafond, laquel­le cuvette 1 d'encastrement est cylindrique et est positionnée à l'envers de telle manière que son rebord 3 vienne buter sous la lame 2 à la périphérie circulaire du trou, laquelle cuvette 1 porte sur sa paroi extérieure des ressorts 4 munis de tiges 5 qui s'appuient sur la face supérieure des lames 2 du pla­fond ; dans laquelle cuvette 1 glisse un support 6 de luminai­re de forme cylindrique. Le support 6 de luminaire a un diamètre légèrement inférieur à la cuvette 1 de façon que ledit support glisse confortablement sur la paroi intérieure de ladite cuvette 1. Cette cuvette 1 comporte une ouverture circulaire 10 en partie supérieure qui est sensiblement égale au diamètre intérieur du support 6 de luminaire. Le support 6 comporte sur la paroi extérieure deux gorges 7 périphériques et légèrement espacées par un plat, dans lesquelles gorges 7 se positionnent, en alternance, un joint torique 8. Le support 6 forme en partie inférieure une collerette 9 périphérique par laquelle on tire pour extraire ledit support 6 de la cuvette 1, et lors de cette opération le joint torique 8 comprimé entre les deux parois sort de sa gorge 7 inférieure et se positionne dans la gorge 7 supérieure. La collerette 9 possède sur toute sa périphérie des encoches 19, régulièrement espacées et orienté­es vers l'extérieur dudit support 6. En se déplaçant vers le bas, le support 6 entraîne l'ensemble comportant : le lumi­naire 11, sa douille 12 et le couvercle de douille 13, lequel couvercle de douille 13 possède deux crochets 14 opposés qui permettent de maintenir cet ensemble solidaire du support 6 par le truchement de deux ressorts 15 qui sont fixés en partie inférieure à des crochets 16 solidaires de la partie supérieu­ re du support 6. Le luminaire 11 repose par la périphérie de sa base sur une butée 17 placée sur la paroi intérieure du support 6 et en partie haute. Le couvercle de douille 13 comporte intérieurement un évidement 18 décroissant en par­tant de la base vers le sommet pour permettre une utilisation avec des douilles de différents types.As shown in Figures 1, 2 and 5, the device comprises a recessing bowl 1 placed in a hole previously made in a blade 2 of the ceiling, which recessing bowl 1 is cylindrical and is positioned upside down such that its rim 3 abuts under the blade 2 at the circular periphery of the hole, which bowl 1 carries on its outer wall springs 4 provided with rods 5 which are supported on the upper face of the blades 2 of the ceiling; into which bowl 1 slides a fixture 6 of cylindrical shape. The luminaire support 6 has a diameter slightly smaller than the bowl 1 so that said support slides comfortably on the inside wall of said bowl 1. This bowl 1 has a circular opening 10 in the upper part which is substantially equal to the inside diameter of the support 6 of luminaire. The support 6 comprises on the outer wall two peripheral grooves 7 and slightly spaced apart by a flat, in which grooves 7 are positioned, alternately, an O-ring 8. The support 6 forms in the lower part a peripheral flange 9 by which one pulls for extract said support 6 from the bowl 1, and during this operation the O-ring 8 compressed between the two walls leaves its lower groove 7 and is positioned in the upper groove 7. The collar 9 has on its entire periphery notches 19, regularly spaced and oriented towards the outside of said support 6. By moving downwards, the support 6 drives the assembly comprising: the luminaire 11, its socket 12 and the cover sleeve 13, which sleeve cover 13 has two opposite hooks 14 which make it possible to maintain this assembly secured to the support 6 by means of two springs 15 which are fixed in the lower part to hooks 16 secured to the upper part re of the support 6. The luminaire 11 rests by the periphery of its base on a stop 17 placed on the inner wall of the support 6 and in the upper part. The socket cover 13 internally has a recess 18 decreasing from the base towards the top to allow use with sockets of different types.

Les éléments suivants: support 6, luminaire 11, douille 12 et couvercle de douille 13 constituent un ensemble amovible.The following elements: support 6, light fixture 11, socket 12 and socket cover 13 constitute a removable assembly.

Les figures 3 et 4 représentent un élément 20 qui s'adapte sur la collerette 9 se trouvant à la base du support 6 de luminaire, lequel élément 20 forme un anneau de section rectangulaire comportant sur sa face intérieure une gorge 21 possèdant des encoches 22 en partie supérieure, lesquelles encoches 22 sont orientées vers le centre de manière qu'en positionnant l'élément 20 sous le support 6, la collerette 9 se loge dans la gorge 21 par le truchement de ces encoches 19 puis une demi-rotation de l'élément 20 permet son blocage sur la collerette 9. La partie inférieure de l'élément 20 est constituée par une collerette intérieure 23 sur laquelle est placé un filtre 24.Figures 3 and 4 show an element 20 which fits on the flange 9 located at the base of the luminaire support 6, which element 20 forms a ring of rectangular section having on its inner face a groove 21 having notches 22 in upper part, which notches 22 are oriented towards the center so that by positioning the element 20 under the support 6, the flange 9 is housed in the groove 21 by means of these notches 19 and then a half-rotation of the element 20 allows its blocking on the collar 9. The lower part of the element 20 is constituted by an internal collar 23 on which a filter 24 is placed.

La collerette 23 porte également des volets 25 de réflexion des ondes lumineuses, lesquels volets 25 pivotent sur des axes 26 et peuvent avoir une forme plate ou courbe.The flange 23 also carries flaps 25 for reflecting light waves, which flaps 25 pivot on axes 26 and may have a flat or curved shape.

Ce type de support amovible est plus particulièrement valable pour des lampes bas voltage à cause de leur faible encombre­ment mais peut être utilisé dans d'autres cas.This type of removable support is more particularly valid for low voltage lamps because of their small size but can be used in other cases.
