Definitions

  • the present invention relates to a ventilation grille for air intakes.
  • Ventilation grilles for air intakes are currently commercially available which substantially comprise a circular or square annular surrounding body, a plurality of parallel and spaced vanes which are monolithic with the frame, and at least one stiffening element that runs from one end of the surrounding frame to the other transversely with respect to the vanes and is also monolithic with the rest.
  • the manufacturer must therefore provide for a plurality of production lines, each assigned to an individual grille model, and the user is furthermore substantially limited in the choice of the grille, which is conceived for a very specific application.
  • AU-A-492 749 discloses a ventilation grille as defined in the preamble of claim 1.
  • a principal aim of the present invention is to provide a ventilation grille for air intakes which, in addition to acting as an effective element for protecting against the entry of foreign objects in ducts or pipes protected thereby, provides great flexibility in application.
  • an object of the present invention is to provide a ventilation grille the production whereof does not require a plurality of production lines, each assigned to a particular model dedicated to specific application characteristics.
  • Another object of the present invention is to provide a ventilation grille the structure whereof is simple and sturdy and is capable of withstanding bad weather, atmospheric agents, shocks, and impacts.
  • Another object of the present invention is to provide a ventilation grille that performs its task for a long time and shows a certain range of adaptation to the diameters and the widths of the ducts or pipes to which it is to be applied.
  • Another object of the present invention is to provide a ventilation grille that can be manufactured at competitive costs with respect to conventional ventilation grilles but can also be produced in models having a pleasant aesthetics.
  • a ventilation grille for air intakes substantially consists, in a first embodiment, of a plurality of elements that can be sold in preassembled form or can be assembled directly by the user and the combinations whereof produce different configurations, each adapted for a particular application.
  • the grille in a first configuration, comprises an annular body 11 that is made of plastics and is monolithic with a plurality of parallel and spaced vanes 12.
  • Said body 11 is provided with a stiffening element 13 that is fixed transversely to the vanes 12.
  • a perimetric seat 14 is formed in the body 11 and is adapted to accommodate, in this case detachably, as explained hereinafter for the other configurations, a frame 17 for supporting means for internal elastic anchoring to an air intake or means for coupling to the intake of a ventilation duct.
  • Two fixing holes 15 for screws of screw anchors or equivalent wall fixing means, not shown, are formed in the body 11 in mutually opposite positions; said holes must be converted into through holes by the user.
  • a different embodiment comprises an insect-blocking mesh 16 that is interposed, on demand, between the body 11 and said frame 17 for the anchoring means, which in this case is adapted to retain the mesh 16 as well.
  • the frame 17 is retained in the seat 14 through a flexible raised portion 14a of the edge of said seat.
  • a first anchoring device in addition to the body 11 described above, there is also provided a first anchoring device, generally designated by the reference numeral 18.
  • the first anchoring device 18 comprises said frame 17, which is accommodated in the seat 14 upon assembly and is provided with a diametrical stiffening cross-member 20 and with two stiffening cross-members 21 that are perpendicular thereto.
  • Two tabs 22 protrude at right angles where the diametrical cross-member 20 and the cross-members 21 intersect, and two coaxial through holes 23 are formed in said tabs; corresponding lateral arms 24 are pivoted in said through holes and protrude from an anchoring element 25.
  • the anchoring element 25 is articulated along one edge with respect to the frame 17.
  • median region of a metallic lamina 26 is embedded and/or inserted at the free end of the anchoring element 25; its radial free ends 27 are adapted to anchor inside the ventilation intake, which is not illustrated.
  • a central arm 28 protrudes from the anchoring element 25 and is interposed between the two lateral arms 24; its free end 29 interferes slightly during rotation and rests on the diametrical cross-member 20 which, by being flexible, produces a removable locking of said anchoring element 25 in an inactive position or in an active position.
  • An abutment tooth 30 protrudes in this case from the frame 17 and is adapted to fit in one of the diametrically opposite cavities 30a provided in the surface that forms the seat 14.
  • a ventilation grille for air intakes comprises, in a third embodiment, an annular body 301, in this case a square one, with which a plurality of parallel and spaced vanes 302 is monolithic.
  • the body 301 is produced by cutting and plastic deformation from metal plate.
  • the grille comprises a plastic frame 303, such as the one previously designated by 17, in which the perimetric part 304 is accommodated and fixed (by seaming) in a seat 305 formed by a perimetric folded edge 306 of the body 301.
  • a mesh 307 is interposed between the frame 303 and the body 301.
  • the anchoring device 18 described earlier can be rigidly coupled to the frame 303.
  • a ventilation grille for air intakes comprises, in a fifth embodiment, an annular body 401 that in this case is circular and with which a plurality of parallel and spaced vanes 402 is monolithic.
  • the body 401 is provided by cutting and plastic deformation from metal plate.
  • the grille 400 comprises a plastic frame 403 such as the one previously designated by 17, in which the perimetric part 404 is accommodated in a seat 405 formed by a partially folded perimetric edge 406 of the body 401.
  • Fixing is performed by folding back flaps 407 formed in the edge 406.
  • a mesh 408 is also interposed, in this case, between the frame 403 and the body 401.
  • the anchoring device 18 described earlier can be rigidly coupled to the frame 403.
  • the ventilation grille according to the invention can be easily preassembled by the retailer or by the user himself, and can adapt to the most disparate application requirements thanks to its multiple configurations.
  • a grille thus conceived does not require a plurality of production lines, since it is simply sufficient to produce the separate parts, which can be assembled in various ways.
  • the grille according to the invention has a solid and strong structure that can be easily applied in any situation and the filtering abilities whereof are absolutely competitive with respect to conventional grilles.
  • the materials and the dimensions may be any according to the requirements.
