Definitions

  • the invention relates to the technical sector of luminaires.
  • 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.
  • 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.
  • 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.
  • the aim of the invention is to remedy these drawbacks, simple, safe, effective and rational way.
  • 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.
  • Each leg or clip remains permanently in the box, mating taking place at the grid.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • the goal is to secure a grid luminaire (1), inside a support box (2), in general quadrangular, made of metal, especially steel.
  • 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.
  • 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.
  • the median fold (3d) gives the common fastening flange (3c), a slightly curved longitudinal profile in the form of a V largely open.
  • 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.
  • 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).
  • 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.
  • 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.
