Abstract
Description
- 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.
- Although such ventilation grilles perform their task, they are not free from drawbacks, the main one being the fact that since they must adapt to several applications, they must be produced in models that differ from one another owing to the provision of particular anchoring means and to the presence of optional auxiliary filtering means.
- 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.
- 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.
- Accordingly, 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.
- This aim, these objects, and others which will become apparent hereinafter are achieved by a ventilation grille for air intakes, comprising a circular or polygonal annular body that is internally monolithic with a plurality of parallel and spaced vanes, and at least one stiffening element arranged transversely to the vanes, said grille being characterized in that a perimetric seat is formed in said annular body and is adapted to accommodate a supporting frame for means for internal elastic anchoring to an air intake or means for coupling to the intake of a ventilation duct.
