Definitions

  • the subject of the present invention is a suspended lighting apparatus.
  • a purpose of the present invention is therefore to provide a suspended lighting apparatus in which the spotlight can be oriented as desired so that it can be appropriately positioned according to the particular lighting requirements.
  • Another purpose of the present invention is to provide a suspended lighting apparatus which can be installed in a simple and economical way, i.e., without having to resort to costly materials or complex technologies.
  • the suspended lighting apparatus is designated, as a whole, by the reference number 10.
  • the suspended lighting apparatus 10 comprises a spotlight 11 provided with a light source 12, and a plurality of slender suspension elements 13 and 14, which, in the example shown in the figures, are steel cables.
  • the steel cables 13 and 14 function as a retention system for a cross member 16, and the spotlight 11 is, in turn, suspended from a fork 15, shaped like an upturned U, which is connected to the cross member 16 in such a way that it can turn.
  • the lighting apparatus 10 is provided with a further slender suspension element 17 which, in a substantially central position, accompanies the electric lead 18 of the apparatus 10 so as to keep it tensioned.
  • the electric lead 18 is connected to the slender suspension element 17 by means of clamps 26.
  • the slender suspension elements 13, 14 and 17 can be obtained by means of steel cables, as already specified, or else by means of thin metal tubes.
  • Figure 5 illustrates the hooking system for the leads 13, 14, obtained by means of balls 27 inserted into recesses or holes 28.
  • the lighting apparatus 10 also has a threaded element 19 which is slotted in the cross member 16 to connect it to the fork 15 in such a way that it is free to turn.
  • the fork 15 is provided with a safety locking element 20, for example a grub screw, which engages with the threaded element 19, the purpose of the arrangement being to configure an articulated joint 23.
  • a safety locking element 20 for example a grub screw, which engages with the threaded element 19, the purpose of the arrangement being to configure an articulated joint 23.
  • a grub screw 25 which makes it possible to block reciprocal rotation of the threaded element 19 and the cross member 16.
  • the spotlight 11 of the lighting apparatus 10 can also turn with respect to the fork 15 thanks to two hinges 21 set on the sides of the spotlight 11 itself.
  • the lighting apparatus 10 is also provided with a device 22 for fast height-adjustment of the position of the apparatus, by adjusting the vertical development of the cables 13, 14 and 17.
  • the height from the floor of the apparatus can be adjusted by means of the device 22, by releasing the steel cables 13, 14 and 17 to increase or decrease their vertical development.
  • the fork 15 can be made to rotate about a substantially vertical axis, by means of the articulated joint 23, consequently causing also the spotlight 11 with its light source 12 to rotate.
  • the spotlight 11 can be made to rotate about a substantially horizontal axis, by means of the hinges 21.
  • the materials, shapes and dimensions of the items illustrated may be any whatsoever according to the requirements, and the said items may be replaced with others that are technically equivalent.
