Definitions

  • the present invention relates to an air grille made from modular elements.
  • Ventilation grilles are known to date.
  • the most conventional ventilation grilles consist of blades fixed to a frame by stapling by means of legs which are folded.
  • Patent FR-A-2,669,408 describes, for its part, a wooden grid produced from blades kept spaced apart, two by two, by means of pairs of bracing pieces, the bracing pieces being made up by a cylinder, each end of which is extended by a lug capable of being housed inside a recess formed in said blades.
  • Patent DE-2,138,041 describes a ventilation grid having the form of a frame in which the blades separated from each other by bracing pieces are deformable to pass from a convex position to a concave position under the action of a pushing force exerted during closing of the frame so as to energize the blade / spacer assembly. This patent severely limits the materials that can be used to manufacture the blades.
  • 2,987,985 describes a ventilation grid affecting the shape of a frame, the grooved uprights of which have an inner lip 28 which serves as a centering member and therefore for positioning the blades. These blades are kept equidistant from each other by means of bracing pieces on which the blades come to bear. These bracing pieces are immobilized inside the groove by the longitudinal edges and the inner lips of the groove. All the ventilation grilles described above have the same drawbacks, namely reduced modularity and an inability to adapt to any format by means of identical standard elements. In addition, these grids do not allow filling of the frame when the uprights and the crosspieces of the latter are assembled, that is to say when the frame is closed.
  • the object of the present invention is to overcome these drawbacks by proposing an air grille made from modular elements all identical regardless of the format of the grid frame to be fixed to the building frame.
  • Another object of the present invention is to provide an air grille capable of being mounted very quickly without requiring the use of specific tools, all the connections of the constituent elements between them being effected by snap-fitting or interlocking.
  • a final object of the present invention is to provide a ventilation grid, the filling of the frame by means of blades and spacers or the change of a blade can be done either in the closed or open state of said frame.
  • the invention relates to a ventilation grille of the type comprising a frame having the general shape of a frame, consisting of lateral uprights provided with an internal groove, connected by crosspieces, and modular elements composed of blades maintained skeleton assembled inside said chassis by means of blade supports constituted by bracing pieces, characterized in that the chassis is lined internally by successive stacking of blades held inside the chassis by fixed spacers by snap-fastening at the ends of each blade, said stackable spacers being resiliently locked between the front edge and the rear edge of the grooves formed in the lateral uprights of said chassis when the blade is inserted into the chassis.
  • the blade is secured to the bracing pieces by means of tongue-and-groove type connections and the front edges of the grooves made in the uprights of the chassis are wider than the rear edges of said grooves to allow filling by the rear face of the frame frame while the latter is in the assembled state closed.
  • the ventilation grille, object of the invention comprises a frame 1 generally affecting the shape of a frame.
  • This chassis 1 consists of lateral uprights provided with an internal groove 4. These uprights are produced by means of profiles such as metal profiles generally in the shape of a U. These lateral uprights are connected by crosspieces also produced by means of metallic profiles which can be identical to the side uprights.
  • These uprights and these crosspieces of the chassis 1 comprise a peripheral slide 5 allowing the reception of angle brackets 10 ensuring the assembly of the constituent elements of the chassis 1, as shown in FIG. 4. This angle bracket 10 is maintained in position by suitable fasteners.
  • the lower crossmember may include through-holes 10 ′ allowing the evacuation of the water capable of penetrating inside the ventilation grid.
  • the sleepers and the uprights also have an interior groove 6 continuous generally median capable of receiving a rod 7, a mosquito net 8 being inserted between the bottom of the groove 6 and this rod 7 and being held in position by means of this rod 7.
  • fixing lugs 9 allow the positioning of the frame 1 in the masonry of the construction to be equipped with such a ventilation grille.
  • the modular elements are composed of blades 2 kept assembled in a skeleton inside said chassis 1 by means of blade supports constituted by bracing pieces 3.
  • the blades 2 are generally formed, as shown in FIG. 1, of substantially rectilinear profiles affecting the shape of a flattened S, each profile having a middle part 2b inclined towards the outside of the grid to facilitate the runoff of water and its non-penetration inside the grid.
  • This middle part 2b is folded back at its ends 2a and 2c, as shown in FIG. 3, to form bent or vertical parts generally parallel to each other forming an obtuse angle with said middle part 2b.
  • These bracing pieces 3 are intended to come to lock elastically inside the grooves 4 formed in the lateral uprights of the chassis 1 between the front edge 4a and the rear edge 4b of these grooves.
  • These grooves 4 are constituted, for example, in FIG. 3, by U-shaped profiles.
  • bracing piece 3 When the vertical branches 3g and 3e of the bracing pieces 3 come to bear respectively against the front 4a and rear 4b edges of the groove 4 of the lateral upright of the chassis 1, the bracing piece 3 is then immobilized at least transversely inside the groove 4 and therefore of the chassis 1.
  • FIG. 2 An example of a blade-spacer connection produced by means of two connection points between the blade 2 and the spacer 3 is shown in FIG. 2.
  • the grooved vertical wing 2d of the blade 2 bears against the anterior body 4a of the groove 4 of the lateral upright of the chassis 1 cooperates with a shoulder 3c formed in the spacer piece 3 in the connection area of the connecting branch 3f of said spacer 3 with the vertical branch 3g resting against the front edge 4a of the groove 4 of the lateral upright of the chassis 1.
  • This tongue-groove connection constitutes a first connection point between the blade 2 and the spacer 3.
  • the vertical wing 2a of the blade 2 bears against the rear edge 4b of the groove 4 of the lateral upright of the chassis 1 is secured by elastic locking at the free end of the vertical branch 3e of the spacer 3 resting against the rear edge 4b of the groove 4 by a link of the tongue-groove type. Thanks to these two connection points, the blade 2 is perfectly held by snap-fastening at its two ends in the chassis 1 by means of the spacer. In addition, to allow the stacking of the spacer pieces 3 inside said groove 4, the free end of the vertical branch 3e of the spacer piece 3 should be secured to a spacer piece 3 arranged above.
  • the connection could again be of the tongue-and-groove type.
  • connection will, for example, be made at the level of the spacer piece 3 from above in the connection area of the horizontal branch 3f of said spacer with its vertical branch 3e bearing against the rear edge 4b of the groove 4 of the lateral upright of the chassis 1.
  • the top part comprises in this connection zone a 3d groove which cooperates with a tongue 3a formed at the end of the branch 3 of the bracing piece from below.
  • the groove 3d and the tongue 3a of the tongue-groove connection are shouldered so that the spacers are immobilized together in the vertical direction.
  • the other vertical branch of the spacer piece 3 from above that is to say that 3g disposed in abutment on the front edge 4a of the groove 4 of the lateral upright of the chassis 1 comes into support against the blade 2 at the level of the face of the top of the vertical wing grooved in said blade 2.
  • the stack is thus perfectly stable.
  • the blades 2 are then cut to the desired length and then at least two bracing pieces 3 are positioned per blade 2.
  • the blades 2 provided with their bracing pieces 3 are introduced from the rear into the chassis 1 forming a frame as shown in the Figure 3 then are slid on the blade 2 towards the bottom of the groove 4 as shown by the arrow so as to come and project from the blade at each of its ends and come to rest between the anterior edges 4a and posterior 4b of the inner groove.
  • the blades 2 provided with spacers can for example be introduced from above into the frame, the sliding movement becoming then useless if the spacer was from the outset projecting at the end of the blade 2.
  • the blades are in this type of configuration of length equal to the distance between the free edges of the rear edges 4b of the grooves 4 of the two lateral uprights defining the frame.
  • these may be of a length corresponding substantially to the distance separating the bottom faces of the grooves 4 formed in the parallel lateral vertical uprights of the chassis 1.
  • This reinforcement may consist of bracing pieces.
