Description

La présente invention concerne un luminaire de forme allongée comportant un corps comprenant au moins une demi coquille appelée "toiture", munie de moyens de fixation à un support quelconque, et une platine allongée portant des éléments fonctionnels internes du luminaire.The present invention relates to an elongated luminaire comprising a body comprising at least a half shell called a "roof", provided with means of attachment to any support, and an elongated plate bearing internal functional elements of the luminaire.

Un luminaire comprenant une toiture de forme allongée est connu du document DE 1 028 688. Selon ce document, un premier et un second groupe de verrous sont placés de chaque grand côté de la toiture, et une liaison mécanique entre les deux groupes permet de placer un groupe en position de libération d'un couvercle transparent appelé habituellement vasque, cependant que l'autre groupe est simultanément placé en position de retenue de la vasque ouverte, ce qui permet, lorsque le luminaire est fixé sous une surface horizontale, que la vasque reste accrochée à la toiture, par exemple pendant le remplacement d'une lampe.A luminaire comprising an elongated roof is known from document DE 1 028 688. According to this document, a first and a second group of latches are placed on each long side of the roof, and a bond mechanics between the two groups makes it possible to place a group in position of release of a transparent cover usually called a bowl, however that the other group is simultaneously placed in the bowl holding position open, which allows, when the luminaire is fixed under a surface horizontal, that the basin remains attached to the roof, for example during the replacement of a lamp.

Un objet de l'invention est de faciliter les interventions de service sur le luminaire, notamment son installation, en permettant à la platine de basculer tout en restant accrochée. L'invention procure l'effet d'accrochage connu, mais avec des moyens plus économiques et appliqués à la platine.An object of the invention is to facilitate service interventions on the luminaire, including its installation, by allowing the plate to tilt while staying hooked. The invention provides the known attachment effect, but with more economical means and applied to the plate.

A cet effet, chacun des bords longitudinaux de la platine est pourvu de parties appelées "parties d'appui", tournées vers l'intérieur de la toiture quand la platine est en position de fonctionnement normal, et la toiture est munie, en regard des parties d'appui, de pièces de soutien présentant une partie de soutien propre à soutenir une partie d'appui de la platine si cette dernière est détachée de la toiture et basculée par rapport à la toiture.For this purpose, each of the longitudinal edges of the plate is provided with parts called "support parts", turned towards the inside of the roof when the plate is in normal operating position, and the roof is provided, in look of the supporting parts, of supporting parts having a part of specific support to support a support part of the plate if the latter is detached from the roof and tilted relative to the roof.

Des modes particuliers de réalisation de l'invention apparaissent dans les revendications dépendantes 2 à 6.Particular embodiments of the invention appear in the dependent claims 2 to 6.

Ces aspects de l'invention ainsi que d'autres aspects plus détaillés apparaítront plus clairement grâce à la description suivante d'un mode de réalisation constituant un exemple non limitatif.

  • La figure 1 représente en coupe un luminaire avec la vasque ouverte et la platine en position normale de fonctionnement.
  • La figure 2 représente en coupe le luminaire avec la vasque enlevée et la platine en position abaissée, position utilisée lors d'une intervention de service sur le luminaire.
  • La figure 3 représente, vue de dessus, une platine nue.
  • La figure 4 représente, en perspective, une pièce de soutien, au dessus d'une partie d'une platine.
    • These aspects of the invention as well as other more detailed aspects will become more clearly apparent from the following description of an embodiment constituting a nonlimiting example.
  • Figure 1 shows in section a luminaire with the bowl open and the plate in the normal operating position.
  • Figure 2 shows in section the luminaire with the bowl removed and the plate in the lowered position, position used during a service intervention on the luminaire.
  • FIG. 3 represents, seen from above, a bare plate.
  • Figure 4 shows, in perspective, a support piece, above a portion of a plate.

    • Le luminaire de la figure 1 comprend entre autres :

    • un corps comportant une demi coquille 1 appelée "toiture", munie de moyens de fixation 35 à un support quelconque, par exemple un plafond,
    • un couvercle transparent ou "vasque" 2, ici basculée vers la gauche pour accéder à l'intérieur du luminaire,
    • une platine 4, faite d'une tôle profilée, portant des élément fonctionnels internes du luminaire : entre autres un ballast 7, des douilles 9 de tubes fluorescents 10.
    The luminaire of FIG. 1 comprises inter alia:
    • a body comprising a half-shell 1 called "roof", provided with means of attachment 35 to any support, for example a ceiling,
    • a transparent cover or "basin" 2, here tilted to the left to access the interior of the luminaire,
    • a plate 4, made of a profiled sheet, carrying internal functional elements of the luminaire: inter alia a ballast 7, sockets 9 of fluorescent tubes 10.

    Chacun des bords longitudinaux (perpendiculaires au plan du dessin) de la platine 4 est pourvu d'une partie 3 repliée appelée "partie d'appui". Cette partie 3 repliée est tournée vers l'intérieur de la toiture 1 quand la platine est en position normale d'utilisation, comme représenté ici.Each of the longitudinal edges (perpendicular to the plane of the drawing) of the plate 4 is provided with a folded part 3 called "support part". This part 3 folded is turned towards the inside of the roof 1 when the plate is in normal position of use, as shown here.

    Des éléments de maintien 20 sont prévus dans la toiture pour s'enclencher avec la partie supérieure des parties 3, afin d'empêcher ces dernières de fléchir vers l'intérieur du luminaire.Holders 20 are provided in the roof to engage with the upper part of the parts 3, in order to prevent the latter from bending towards the interior of the luminaire.

    La toiture 1 est munie de pièces de soutien 8L, 8R possédant chacune une partie de soutien 6.The roof 1 is provided with support pieces 8L, 8R each having a support part 6.

    La figure 2 montre le même luminaire dans une position où la platine 4 est basculée vers la gauche, avec les éléments qu'elle porte. La vasque a été enlevée pour permettre de basculer complètement la platine jusqu'en position verticale. La partie pliée 3 de la platine est soutenue par la partie de soutien 6 de la pièce de soutien 8L. Il est clair que le système est symétrique et que la même platine aurait pu aussi bien être basculée vers la droite, en restant accrochée à la pièce de soutien 8R de droite.Figure 2 shows the same luminaire in a position where the plate 4 is tilted to the left, with the elements it carries. The basin has been removed to allow the plate to tilt completely to the position vertical. The folded part 3 of the plate is supported by the support part 6 of the support piece 8L. It is clear that the system is symmetrical and that the same deck could just as well have been tilted to the right, remaining attached to the right support piece 8R.

    Sur la figure 3, la platine 4 comporte, de façon symétrique sur chacun de ses côtés longitudinaux, un bord 3 replié, et elle est munie de quatre orifices 11. La partie 3 pourrait aussi être rapportée au lieu d'être pliée à partir de la tôle de la platine elle-même. Elle pourrait être présente seulement en certains points sur la longueur de la platine, au niveau des pièces de soutien 8 de la figure 1.In FIG. 3, the plate 4 comprises, symmetrically on each of its longitudinal sides, a folded edge 3, and it is provided with four orifices 11. Part 3 could also be brought back instead of being folded from the sheet metal of the plate itself. It could be present only in certain points along the length of the plate, at the support pieces 8 of the figure 1.

    La partie notée "fig. 4" est représentée à nouveau sur la figure 4, où sont représentés à plus grande échelle la partie pliée 3 et un orifice 11. Cet orifice rectangulaire comporte une partie 18 élargie sur une longueur inférieure à celle de l'orifice lui-même.The part marked "fig. 4" is shown again in figure 4, where are shown on a larger scale the folded part 3 and an orifice 11. This orifice rectangular has a part 18 widened over a length less than that from the orifice itself.

    La pièce de soutien 8 comprend une partie supérieure 12 ici horizontale destinée à sa fixation à la toiture 1, et une partie de soutien 6, quasi horizontale, légèrement montante. Cette pièce de soutien 8 constitue en outre un crochet possédant, en plus de la partie de soutien 6, des moyens de retenue de la platine en position normale : la partie de soutien 6 est prolongée vers le bas par une partie verticale munie d'ailes 14, elle-même prolongée par une partie 13 repliée horizontalement ou montant légèrement.The support piece 8 comprises an upper part 12 here horizontal intended for its attachment to the roof 1, and a support part 6, almost horizontal, slightly rising. This support piece 8 further constitutes a hook having, in addition to the support part 6, retaining means of the plate in normal position: the support part 6 is extended towards the bottom by a vertical part provided with wings 14, itself extended by a part 13 folded horizontally or slightly rising.

    Lorsque la platine est en position normale, la partie inférieure du crochet pénètre dans la fente 11, le crochet est pressé vers la gauche sur la figure par son élasticité propre, sa partie 17, au-dessus des ailes 14, est insérée dans la partie 18 de la fente 11, et les ailes 14 retiennent la platine. Lorsque la partie inférieure du crochet est repoussée un peu vers la droite par un utilisateur, la platine peut descendre jusqu'à la partie 13. Si la partie inférieure du crochet est repoussée plus fortement encore vers la droite, la platine peut échapper de la partie 13 et être complètement libérée. Ces moyens permettent donc le déclenchement partiel ou total à volonté.When the plate is in normal position, the lower part of the hook enters slot 11, the hook is pressed to the left in the figure by its own elasticity, its part 17, above the wings 14, is inserted in the part 18 of the slot 11, and the wings 14 retain the plate. When the party of the hook is pushed a little to the right by a user, the plate can go down to part 13. If the lower part of the hook is pushed even more strongly to the right, the plate may escape from part 13 and be completely released. These means therefore allow partial or total trigger at will.

    En variante, une seule aile 14 peut suffire, la partie 18 étant alors placée dissymétriquement par rapport à la fente 11. La dimension relative des parties 13, 14, 17 vis-à-vis de celle de la partie 6 a peu d'importance puisque leurs fonctions sont différentes. On pourrait en outre facilement imaginer que des crochets, d'une part, comprenant les parties 17, 14, 13, et des parties de soutien 6, d'autre part, soient portés par des pièces distinctes.Alternatively, a single wing 14 may suffice, the part 18 then being placed asymmetrically with respect to the slot 11. The relative size of the parts 13, 14, 17 vis-à-vis that of part 6 is of little importance since their functions are different. One could also easily imagine that hooks, on the one hand, comprising parts 17, 14, 13, and parts of support 6, on the other hand, are carried by separate parts.

    Pour déplacer la platine de la position de la figure 1 à celle de la figure 2, les crochets 8L de gauche sont légèrement poussés vers la droite, ceci permet à la platine d'échapper aux ailes 14 et de descendre sur la partie 13, puis les crochets 8R de droite sont fortement poussés vers la gauche pour libérer totalement la platine du côté droit. Lors d'un appui latéral sur un crochet, la platine, avant son basculement, ne peut bouger car elle est appuyée sur les parois de la toiture à droite et à gauche. Du fait de la légère descente de la partie gauche de la platine, sa partie 3 échappe aux éléments de maintien 20 et, comme indiqué par la flèche 15, vient s'appuyer sur la partie 6 du crochet, pendant que l'ensemble de la platine bascule comme indiqué par la flèche 16.To move the stage from the position of figure 1 to that of figure 2, the 8L hooks on the left are slightly pushed to the right, this allows the plate to escape from the wings 14 and to descend on the part 13, then the right 8R hooks are pushed strongly to the left to release completely the plate on the right side. When pressed sideways on a hook, the plate, before tilting, cannot move because it is pressed on the roof walls on the right and on the left. Due to the slight descent of the left side of the plate, its part 3 escapes from the holding elements 20 and, as indicated by arrow 15, comes to rest on part 6 of the hook, while the whole plate swings as indicated by arrow 16.

    Il doit être compris que le verbe "comprendre" n'exclut pas la présence d'autres éléments ou étapes que celles listées dans une revendication.It should be understood that the verb "to understand" does not exclude the presence elements or steps other than those listed in a claim.
