Definitions

  • the support box is to be made of an insulating and fire-retardant material, similar to the material used for electric plug sockets, and is mainly characterised in that it is easily adaptable to the diameter of the spotlights used.
  • a horizontal cut is made which reduces the length of the truncoconical lower part of the box to a desired size; the truncoconical lower part is formed by a succession of rings, or circular steps, which are concentric and increase in diameter one-by-one in an upwards direction, in this way defining a number of cutting external planes.
  • Both the box body and the cover thereof exhibit some predisposed fracture zones so that material can easily be removed when a passage for sleeves of electric wires is required, or for dispersion of heat.
  • the main body (A) as in the above-identified patented support box, is practically truncoconical in the lower part thereof, which lower part is formed by a succession of concentric rings (A1) having a growing diameter in an upwards one-by-one direction.
  • the concentric rings (A1) are joined together by radial strips (A2) made of the same material and therefore easily cuttable in cases where the suitable ring (A1) corresponding to the spotlight diameter has been identified and the smaller rings in excess are to be cut away.
  • Some improvements in the present invention related to the upper part (A3) of the main body (A), i.e. the part thereof which is located above the rings (A1) and which is destined to receive the cover (B).
  • two or more holed appendages (A4) each exhibiting a vertical succession of practically cylindrical portions which are coaxial and exhibit a decreasing diameter one-by-one in a downwards direction, and are of a same height dimension as corresponding rings (A1) of the main body (A), so that easily alignment there-with can be achieved after suitable cutting for installation of each spotlight has been made.
  • the holed appendages (A4) enable means for fastening to be inserted (nails, screws or other), chosen according to the installation surface involved: plasterboard, aluminium panels, wooden planks for cement castings and so on.
  • An opening (A5) is afforded in the upper part (A3) of the main body (A) for rapid attachment of the secondary body (C, figure 2), thanks to which the electronic transformer can be housed in a separate chamber to the chamber housing the spotlight, but which according to needs can be in communication there-with simply by removing a special snap-fastened closure element (E) achieving an effective thermal insulation between the two adjacent chambers, the chamber housing the heat source in the main body (A) and the chamber housing the transformer in the secondary body (C).
  • the secondary body (C) is formed by a frontal coupling of two shells (C' and C"), (figure 2 - 9 and 11) predisposed for this purpose, along the join edges, by male-female coupling.
  • the coupling also enables, at an opposite end from an end which is to be inserted in the main body (A), a dove-tail coupling of a support foot (D) with which aligned fixture is achieved with the holed appendage (D1) which is identical to the holed appendages (A4) of the main body (A) and, like the holed appendages (A4), can be height-adapted by a simple cut in accordance with how the rings (A1) and the appendages on the main body (A) have been cut.
  • the secondary body (C) is inserted into the main body (A) up to the position of the stops constituted by the relieves (C4), against the external frame of the opening (A5); the wedge-shaped ridges (C5) cross into the main body (A) and snap-fasten thereto (figure 10), preventing accidental separation of the two bodies (A and C).
  • ridges (C6) are predisposed internally of the main body (C) for snap-fastening to the closure element (E) and in particular the flat wall (E1) when the wall (E2), shaped to follow the curvature of the main body (A), rests perfectly against the complementarily-shaped edge of the secondary body (C).
  • the two walls (E1 and E2), which enable separation of the spotlight chamber from the transformer chamber with a heat-insulating hollow space, are both predisposed along the perimeter edge with one or two recesses (E4) of a sufficient size to allow passage of connection cables from the spotlight to the transformer.
  • the closure element (E) Since access to the built-in support box once installed is possible only through the fixture hole of the spotlight, in the wall (E2) thereof the closure element (E) exhibits a sort of small handle (E3) or the like, on which a screwdriver can be applied from the outside and through the above-mentioned hole, both for removing the element (E) and for repositioning it in order to obtain the snap-fastening using a finger.
  • Two or more truncoconical clutches (C7) are afforded externally of the secondary body (C), in the opposite vertical face thereof and located towards the end to be inserted in the main body (A).
  • the truncoconical clutches (C7) have a larger radius thereof facing externalwards and offer a pressure-fit for passage sleeves of the electric cables at a predisposed fracture zone (C8).
  • the ridges remaining after fracture prevent insertion of the tube internally of the secondary body (C) and the consequent risk of obstruction of passage of the transformer, both during the insertion stage and the extraction stage, when it is to be replaced.
