Abstract
Description
L'invention se rattache au secteur technique des luminaires.The invention relates to the technical sector of luminaires.
Plus particulièrement, l'invention concerne un luminaire du type de ceux présentant un caisson support recevant des lampes avec les composants nécessaires à l'allumage et au fonctionnement et un ensemble optique sous forme d'une grille, pour notamment diffuser la lumière et contrôler les luminances.More particularly, the invention relates to a luminaire of the type of those with a support box receiving lamps with the components needed for ignition and operation and a set in the form of a grid, in particular for diffusing light and control the luminances.
Le problème que se propose de résoudre l'invention se situe au niveau de la fixation de la grille par rapport au caisson support, en ayant pour but d'assurer la continuité électrique de masse entre le support et la grille.The problem to be solved by the invention lies in level of the fixing of the grid relative to the support box, having purpose of ensuring the electrical continuity of mass between the support and the wire rack.
Différentes solutions techniques ont été proposées pour obtenir ce résultat.Various technical solutions have been proposed to obtain this result.
On peut citer, par exemple, l'enseignement du brevet FR 2.736.994
qui concerne un système de fixation de grille de luminaire avec continuité
de masse. Pour l'essentiel, ce système de fixation est constitué d'un boítier
métallique comportant plusieurs bras élastiques convenablement profilés
pour constituer une chicane de verrouillage. Cette chicane coopère avec une
zone d'encliquetage d'une barrette de suspension qui présente une languette
élastique permettant la suspension de la grille du luminaire.
Compte tenu de ces dispositions, il apparaít que le système nécessite
l'utilisation de deux ensembles indépendants, à savoir le boítier métallique
et la barrette de suspension.There may be mentioned, for example, the teaching of patent FR 2,736,994 which relates to a lighting grid fixing system with continuity of mass. For the most part, this fastening system consists of a metal housing comprising a plurality of resilient arms suitably profiled to form a locking baffle. This baffle cooperates with a latching zone of a suspension bar which has an elastic tongue allowing the suspension of the luminaire grille.
Given these provisions, it appears that the system requires the use of two independent sets, namely the metal housing and the suspension bar.
Plus généralement, on a proposé différents types d'agrafes
métalliques pour assurer la fixation de la grille par rapport au caisson
support. Quelle que soit la forme de réalisation de ces agrafes, il apparaít
que ces dernières sont fixées sur la grille. Il en résulte des difficultés
importantes au moment de la mise en place de la grille, en considérant le
fait que ces agrafes doivent être engagées dans des ouvertures que
présentent généralement deux bords opposés du caisson, étant rappelé que
l'on travaille le plus souvent en hauteur, par exemple sur un escabeau dans
une position inconfortable.
On observe également que ce type d'agrafes ne permet pas toujours
d'assurer une bonne continuité électrique de masse qui peut partiellement
être interrompue par la peinture ou autre revêtement du caisson support,
notamment au niveau des fentes dans lesquelles sont clipées les agrafes de
suspension.More generally, various types of metal staples have been proposed for fixing the grid with respect to the support box. Whatever the embodiment of these staples, it appears that the latter are fixed on the grid. This results in significant difficulties at the time of installation of the grid, considering the fact that these staples must be engaged in openings that generally have two opposite edges of the box, being reminded that we work most often in height, for example on a stepladder in an uncomfortable position.
It is also observed that this type of staples does not always make it possible to ensure good electrical ground continuity which can be partially interrupted by the paint or other coating of the support box, in particular at the slots in which the suspension clips are clipped. .
L'invention s'est fixée pour but de remédier à ces inconvénients, de manière simple, sûre, efficace et rationnelle.The aim of the invention is to remedy these drawbacks, simple, safe, effective and rational way.
Le problème que se propose de résoudre l'invention est de pouvoir pré-équiper le caisson support d'agrafes de suspension en ayant pour objectif de permettre une fixation rapide et visuelle de tout type de grille de luminaire, sur tout type de caisson support encastré ou non, en assurant une parfaite continuité électrique de masse.The problem that the invention proposes to solve is to be able to pre-equip the support box with suspension clips, objective to allow rapid and visual fixation of any type of luminaire, on any type of recessed or non-recessed support perfect electrical continuity of mass.
Pour résoudre un tel problème, il a été conçu et mis au point un
dispositif de fixation d'une grille de luminaire dans un caisson métallique
avec une pluralité de pattes ou d'agrafes déformables élastiquement et aptes
à assurer une continuité de masse.
Selon une caractéristique à la base de l'invention, chaque patte ou
agrafe présente des agencements pour permettre successivement :
- son accouplement dans des agencements complémentaires du caisson, en vue de son maintien temporaire en position escamotée de rabattement ;
- son basculement en dehors du plan de base dudit caisson pour permettre l'accrochage de la grille ;
- son enfoncement dans les agencements du caisson et son blocage en
position escamotée verticale correspondant au positionnement et au
maintien de la grille à l'intérieur dudit caisson ;
chacune desdites pattes présentant un profil apte à exercer un effort de friction au niveau desdits agencements du caisson, pour mettre à nu le métal dudit caisson.
According to a characteristic underlying the invention, each leg or clip has arrangements for successively:
- its coupling in complementary arrangements of the box, for its temporary retention in retracted position of folding;
- its tilting out of the base plane of said box to allow the attachment of the grid;
- its depression in the arrangements of the box and its locking in the vertical retracted position corresponding to the positioning and maintenance of the gate inside said box;
each of said tabs having a profile adapted to exert a frictional force at said arrangements of the box, to expose the metal of said box.
Chaque patte ou agrafe reste à demeure dans le caisson, l'accouplement s'effectuant au niveau de la grille.Each leg or clip remains permanently in the box, mating taking place at the grid.
Pour résoudre le problème posé d'assurer les trois fonctions distinctes que présente chacune des pattes ou agrafes, les agencements de la patte sont constitués par deux branches de section méplate réunies à l'une de leurs extrémités par un rebord équerré d'accrochage commun plié dans sa partie médiane pour maintenir écartées lesdites branches selon une valeur angulaire déterminée, l'extrémité libre des branches présentant un rebord équerré d'accrochage.To solve the problem of ensuring the three functions each of the legs or staples, the arrangements of the leg are constituted by two branches of flat section joined to one their ends by a squared common hanging edge folded into its middle part to maintain spaced said branches according to a value defined angle, the free end of the branches with a rim squared hooking.
Pour résoudre le problème posé de pré-équiper le caisson support, le rebord équerré d'accrochage commun, coopère avec les agencements du caisson sous forme d'une fente, tandis que les rebords équerrés d'accrochage de l'extrémité libre des branches, coopèrent, après rapprochement angulaire par élasticité desdites branches, avec des fentes que présente un profilé formé à partir d'au moins deux côtés opposés de la grille.To solve the problem of pre-equipping the support box, the squared flange common hook, cooperates with the arrangements of the box in the form of a slot, while the squared edges attachment of the free ends of the branches, cooperate, after angular approximation by elasticity of said branches, with slots a profile formed from at least two opposite sides of the wire rack.
Pour résoudre le problème posé d'assurer un accouplement sûr et efficace de l'ensemble de la grille par rapport aux différentes pattes ou agrafes de suspension, les rebords équerrés d'accrochage de l'extrémité libre des branches, présentent, au niveau de leur raccordement avec lesdites branches, des découpes aptes à assurer le verrouillage desdits rebords après engagement dans la fente correspondante et relâchement des branches.To solve the problem of ensuring safe and reliable mating effective of the entire grid with respect to the different legs or suspension staples, the squeegee hanging flanges of the end free branches, present, at their connection with said branches, cutouts capable of locking said flanges after engagement in the corresponding cleft and loosening of the branches.
Pour résoudre le problème posé d'assurer le positionnement en hauteur de la grille à l'intérieur du caisson et son accouplement, les bords rectilignes externes des branches présentent au moins une encoche apte à coopérer, sous l'effet de l'élasticité des branches, avec les extrémités de la fente du caisson pour assurer le blocage en position escamotée verticale de la patte correspondant au positionnement de la grille à l'intérieur du caisson.To solve the problem of ensuring positioning in height of the grid inside the box and its coupling, the edges external rectilinear branches have at least one notch suitable for cooperate, under the effect of the elasticity of the branches, with the ends of the slot of the box to ensure the locking in the vertical retracted position of the tab corresponding to the positioning of the grid inside the caisson.
Pour résoudre le problème posé d'assurer une parfaite continuité électrique de masse, les bords rectilignes externes des branches présentent des arêtes vives pour exercer l'effort de friction au niveau des fentes d'introduction du caisson qui, grâce à une forme circulaire de leurs extrémités, permet d'avoir quatre points de contact par ressort.To solve the problem of ensuring perfect continuity electric mass, the outer rectilinear edges of the branches present sharp edges to exert the frictional force at the slits introduction of the caisson which, thanks to a circular form of their ends, allows to have four points of contact per spring.
Il en résulte que l'effort de friction a pour effet d'enlever la peinture ou autre que présente le caisson, notamment au niveau des fentes d'introduction recevant des différentes agrafes de suspension. As a result, the friction force has the effect of removing the paint or other that presents the box, especially at the level of the slots of introduction receiving different suspension clips.
Selon une autre caractéristique, le rebord d'accrochage commun et les rebords d'accrochage de l'extrémité libre des branches, sont orientés dans le même sens, en direction de l'intérieur du caisson.According to another characteristic, the common fastening flange and the hooking edges of the free end of the branches are oriented in the same direction, towards the inside of the box.

Comme indiqué, le but recherché est d'assurer la fixation d'une grille de luminaire (1), à l'intérieur d'un caisson support (2), en général quadrangulaire, réalisé en métal, notamment en acier.As stated, the goal is to secure a grid luminaire (1), inside a support box (2), in general quadrangular, made of metal, especially steel.
La grille (1) du luminaire peut présenter, par exemple, deux côtés latéraux (1a) entre lesquels sont accouplées des lamelles disposées généralement à la façon d'une grille. The grid (1) of the luminaire may have, for example, two sides sides (1a) between which are arranged lamellae arranged usually in the manner of a grid.
Selon une caractéristique à la base du dispositif selon l'invention, la
fixation de la grille à l'intérieur du caisson (2) s'effectue au moyen
d'agrafes ou pattes de suspension spéciales (3) destinées à pré-équiper le
caisson (2). Chaque patte ou agrafe (3) est constituée par deux branches
rectilignes de section méplate (3a) et (3b) réunies à l'une de leurs extrémités
par un rebord équerré d'accrochage commun (3c). Ce rebord d'accrochage
(3c) présente, sensiblement dans sa partie médiane, une ligne de pliage (3d)
pour maintenir écartées les branches (3a) et (3b) selon une valeur angulaire
déterminée. Autrement dit, le pli médian (3d) confère au rebord
d'accrochage commun (3c), un profil longitudinal légèrement cintré sous
forme d'un V grandement ouvert.
Compte tenu de ces dispositions, les deux branches (3a) et (3b)
peuvent être rapprochées l'une de l'autre par élasticité en position jointive
pour permettre notamment l'accrochage de la grille de luminaire (1),
comme il sera indiqué dans la suite de la description.According to a feature at the base of the device according to the invention, the fixing of the grid inside the box (2) is effected by means of special clips or suspension lugs (3) intended to pre-equip the box (2). Each tab or staple (3) is constituted by two rectilinear branches of flat section (3a) and (3b) joined at one of their ends by a squared common gripping flange (3c). This hooking flange (3c) has, substantially in its middle part, a fold line (3d) to keep apart the branches (3a) and (3b) according to a determined angular value. In other words, the median fold (3d) gives the common fastening flange (3c), a slightly curved longitudinal profile in the form of a V largely open.
Given these provisions, the two branches (3a) and (3b) can be brought closer to each other by elasticity in contiguous position to allow in particular the attachment of the luminaire grille (1), as will be indicated in the following description.
L'extrémité libre des branches (3a) et (3b) présente chacune un rebord équerré d'accrochage (3e) et (3f). Le rebord (3c) et les rebords (3e) et (3f) sont orientés dans la même direction. Le corps de l'agrafe est réalisé dans un métal présentant une élasticité et une résistance suffisantes.The free ends of the branches (3a) and (3b) each have a square edge of hooking (3e) and (3f). The flange (3c) and the flanges (3e) and (3f) are oriented in the same direction. The body of the staple is realized in a metal having sufficient elasticity and strength.
Le rebord équerré d'accrochage commun (3c) coopère avec des fentes (2a) que présente, par exemple, une nervure (2b) que présente la face interne des côtés latéraux ou transversaux du caisson. Les rebords équerrés d'accrochage (3e) et (3f) que présente l'extrémité libre de chacune des branches (3a) et (3b) coopèrent, après rapprochement angulaire des branches (3a) et (3b), dans des fentes (1b) que présente un profilé formé à partir de deux côtés opposés (1a) de la grille (1). The squared common locking flange (3c) cooperates with slots (2a) that have, for example, a rib (2b) that has the face internal lateral or transverse sides of the box. The squared ledges (3e) and (3f) that has the free end of each of the branches (3a) and (3b) cooperate, after angular branches (3a) and (3b), in slots (1b) provided by a profile formed from two opposite sides (1a) of the grid (1).
Enfin, pour assurer le blocage des agrafes de suspension (3) par rapport aux bords correspondants du caisson, les bords rectilignes externes des branches (3a) et (3b) présentent des encoches (3g) aptes à coopérer, sous l'effet de l'élasticité des branches, avec les extrémités de la fente du caisson.Finally, to ensure the locking of the suspension clips (3) by relative to the corresponding edges of the box, the outer rectilinear edges branches (3a) and (3b) have notches (3g) capable of cooperating, under the effect of the elasticity of the branches, with the ends of the slot of caisson.
Compte tenu de ces caractéristiques, la fixation de la grille par rapport au caisson, s'effectue d'une manière particulièrement simple et efficace, et dans de très bonnes conditions. On se réfère aux figures 6, 7, 8 et 9 des dessins.Given these characteristics, the fixing of the grid by compared to the box, is carried out in a particularly simple and effective, and in very good conditions. Referring to Figures 6, 7, 8 and 9 drawings.
D'une manière importante, on observe, tout d'abord, qu'il est
parfaitement possible de pré-équiper le caisson de pattes ou agrafes de
suspension (3). Dans ce but, le rebord d'accrochage commun (3c) est
engagé dans les fentes (2a) du caisson (2), de manière à assurer le maintien
temporaire en position escamotée de rabattement, de l'agrafe dans un plan
sensiblement horizontal (figure 6). Cette mise en place peut par exemple
être préalablement effectuée à l'atelier.
On observe que les différentes agrafes sont parfaitement maintenues
sous l'effet de l'élasticité des branches au niveau du rebord (3c), ce qui ne
gêne pas la manipulation et le stockage du caisson étant donné que rien ne
déborde de ce dernier.Importantly, it is observed, firstly, that it is perfectly possible to pre-equip the box with legs or suspension clips (3). For this purpose, the common hooking flange (3c) is engaged in the slots (2a) of the box (2), so as to ensure the temporary retention in the retracted position of folding, the staple in a substantially horizontal plane ( Figure 6). This setting up can for example be carried out beforehand at the workshop.
It is observed that the various staples are perfectly maintained under the effect of the elasticity of the branches at the rim (3c), which does not interfere with the handling and storage of the box since nothing exceeds the latter.
Il suffit ensuite de tirer manuellement chacune des agrafes au niveau de son rebord (3c) en direction du bas et dans un plan sensiblement vertical pour permettre l'accrochage de la grille (figure 7).Then just manually pull each of the staples at the level from its rim (3c) downwards and in a substantially vertical plane to allow the hooking of the grid (Figure 7).
Il suffit ensuite de rapprocher par élasticité les branches (3a) et (3b)
pour le positionner de manière sensiblement jointive afin de pouvoir
engager les rebords équerrés d'accrochage (3e) et (3f) dans les fentes que
présente les bords latéraux de la grille. Après engagement, les branches sont
relâchées.
On observe à cet égard que les rebords équerrés d'accrochage (3e) et
(3f) présentent, au niveau de leur raccordement avec les branches (3a) et
(3b), des découpes (3h) aptes à assurer le verrouillage desdits rebords après
engagement dans les fentes correspondantes et relâchement des branches,
comme indiqué (figure 8).It then suffices to bring the branches (3a) and (3b) closer together in order to position it in a substantially contiguous manner in order to be able to engage the squared-off catching edges (3e) and (3f) in the slots that the lateral edges of the wire rack. After engagement, the branches are released.
In this respect, it can be observed that the squared catching edges (3e) and (3f) have, at their connection with the branches (3a) and (3b), cutouts (3h) capable of locking said flanges after engagement in the corresponding slots and loosening of the branches, as shown (Figure 8).
Il suffit ensuite de pousser la grille suspendue par les agrafes, qui vont pénétrer au travers des fentes du caisson, jusqu'au moment où les encoches (3g) coopèrent avec les extrémités de la fente assurant le blocage en position (figure 9).Then simply push the grid suspended by the staples, which will penetrate through the cracks of the caisson, until the moment when the notches (3g) cooperate with the ends of the slot ensuring the locking in position (Figure 9).
On observe que les bords rectilignes externes des branches (3a) et (3b) à partir desquelles sont formées les encoches de verrouillage (3g), présentent des arêtes vives pour exercer un effort de friction au niveau des fentes d'introduction du caisson en combinaison avec l'élasticité des branches. Cet effort de friction a pour effet d'enlever la peinture ou autre revêtement du caisson au niveau de la fente permettant d'assurer une parfaite continuité électrique de masse. Les extrémités des fentes d'introduction ont une forme circulaire permettant d'avoir quatre points de contact par agrafe.It is observed that the rectilinear outer edges of the branches (3a) and (3b) from which the locking notches (3g) are formed, have sharp edges to exert frictional force at the level of box introduction slots in combination with the elasticity of the branches. This friction force has the effect of removing paint or other coating the box at the slot to ensure a perfect electrical continuity of mass. The ends of the slits have a circular shape allowing to have four points of staple contact.
Les avantages ressortent bien de la description.The advantages are apparent from the description.
