Definitions

  • the present invention relates to a device for adjustably coupling or affixing lighting assemblies to false ceilings, in particular false ceilings of the type consisting of section members and/or panels.
  • a problem related to the construction of the mentioned false ceilings is that of coupling or affixing to said false ceilings single lighting as­semblies, generally consisting of box-like lampholders, frequently having a very large size, and provided for housing therein one or more fluorescent lamps.
  • This lighting assemblies are conventional strictlyly affixed by using rather complex devices which are generally assembled after the assembling of the false ceiling and, accordingly, require a lot of manual labour.
  • the task of the present in­vention is to provide a device for coupling lighting assemblies to false ceilings, of the indicated type, which may be easily and quickly associated to the false ceiling as this latter is constructed, so as to require a very reduced amount of manual labour for the subsequent application of the lampholders to said false ceiling.
  • a main object of the present invention is to provide a device for coupling lighting assemblies to the false ceilings of the indicated type, which affords the possibility of affixing said lampholder in an adjustable way, in order to change, as desired, the distance of the lampholder from said false ceiling, within a very broad distance range.
  • Another object of the present invention is to provide a device for adjustably coupling lighting assemblies to false ceilings, in particular to false ceilings formed by section members and panels, which comprises a very reduced number of component parts and which, in the meanwhile, affords the possibility of precisely adjusting the distance of the lampholder from the false ceiling.
  • Yet another object of the present invention is to provide a coupling device which is adapted to support, in a very reliable way, the single lighting assemblies, at their ends.
  • Yet another object of the present invention is to provide such a coupling device which can be easily adapted to all of the fluorescent lampholders which are at present commercially available.
  • Yet another object of the present invention is to provide a device for adjustably coupling light­ing assemblies to false ceilings, in particular false ceilings of the type formed by section members and metal panels, which has a very reduced cost.
  • a device for adjustably coupling lighting assemblies to false ceilings in particular to false ceilings of the type formed by section members and/or metal panels, having the characteristics claimed in claim 1.
  • the ad­justable coupling device according to the invention has been herein indicated at the reference number 1, and supports, at one end thereof, a lampholder 2, preferably of the fluorescent lamp type.
  • the adjustable coupling device 1 comprises a substantially parallelepipedal box-like body 3, having an open face, which may be snap fitted to the end of the lampholder 2, and an opposite closed face 4.
  • two integral ribs 5 and 6 which longitudinally extend along a portion of the height of the face 4 of the half-box shaped body 3.
  • the ribs 5 and 6 are provided, at the top thereof, with a substantially rectangular cross-­section which is enlarged at the bottom into two op­posite portions, thereon there are defined opposite rack portions 7 and 8; each said rack portion is provided with a plurality of teeth having a substantial­ly rectangular cross-section.
  • the half-box shaped body 3 is provided with a peripheral edge 9 at the center of which there is defined a substantially rectangular cross-section seat indicated at the reference num­ber 10.
  • This seat 10 as shown in figure 1, is provided at a substantially intermediate longitudinal position with respect to the face 4 of the body 3, and the width of the seat 10 substantially corre­sponds to the transverse distance of the two rack portions 7 and 8.
  • the half-box shaped body 3 is provided for association with lamp holder 2 by means of a simple insertion and, if desired, it may be firmly affixed thereto by means of any suitably means, for example by glueing.
  • the adjustable coupling device 1 comprises, moreover, as a main part thereof, a preferably metallic small plate, indicated overally at the reference number 11.
  • This composite small plate 11 comprises a first flat portion, which substantially vertical­ly extends and has a rectangular shape, being in­dicated at 12, therewith there is associated, for example by means of welding, a further plate portion 13 of substantially L-shape.
  • the L-shape small plate 13 may be affixed to the flat portion 12 by means of any known means: for example by welding to said flat portion 12 a tab portion 14 bent at a right angle and upwardly extending.
  • the L-shaped flat portion 13 is welded to the vertically extending flat portion or small plate 12 so as that the greater leg of the L lies in a substantially horizontal plane, and crosses the vertically extending flat portion 12 at a given height.
  • the vertically extending flat por­tion 12 will be divided, from the greater leg of the L, into a lower portion 15 and a top portion 16.
  • the flat portion 12, in particular, may be further stabilized by means of a rivet to be in­serted into the mentioned slot 19 and hole 20.
  • the shorter leg 23 of the L is bent at a right angle and extends substantially downwardly.
  • the composite small plate 11 will be directly in­stalled and, to this end, it will be affixed, for example, to an element 24 of the false ceiling, by means of suitable bolt and nut assemblies 25, engaged in an adjustable way in the slots 21 and 22 and coup­ling the composite plate 11 to the section member 24.
  • two half-box shaped bodies 3 will be affixed to the ends of the lamp­holders 2, and each body 3 will be snap engaged, by means of the cooperation of the teeth of the rack portions 7 and 8 and teeth 17 and 18 of the flat portion 12 so as to affix, at the desired distance from the false ceiling, the lamp holder 2.
  • the slot 19 of the vertically extending flat portion 12 will be registered with respect to the hole 20 and, through the slot 19 and hole 20 any suitably permanent af­fixing means will be introduced, such as, for example, the rivet 26 shown in particular in figure 3.
  • Figure 4 shows the lamp-holder 2 fixed to the false ceiling at the two ends thereof, by using two adjustable coupling devices 1 according to the invention.
  • the false ceiling consisting of panels P
  • the room ceiling S by means of any known means, for example suspending wires F.
  • the lampholder 2 may be affixed to the ceiling in a very stable and safe way.
  • a further aspect which con­tributes to improving this coupling is the stabilizing stress of the moment exerted by the weight of the lampholder and each composite plate 11 associated with the coupling devices 1 applied to the ends of said lampholder 2.
