Definitions

  • the present invention relates to a ventilation grille intended to be interposed between an interior space and an exterior atmosphere capable of being subjected to splashing water or snow from bad weather and comprising a plate or sheet in which are formed openings general elongated rectangular, separated by elongated full intervals of the plate or sheet, each rectangular opening being covered towards the outside by a rectangular trigger guard placed at a distance d from the surface of the plate which is clearly less than the width of the rectangular openings , to delimit a pair of lateral ventilation openings capable of opposing the crossing of even powdery snow, each trigger guard being connected to the plate at each of its ends by a connection part inclined relative to the plate.
  • the invention also relates to ventilation elements comprising such ventilation grilles, as well as to the use of such grids.
  • This grid consists of a metal plate from which rectangular blades have been cut and pushed so as to create air slots.
  • Certain ventilation grilles in particular those which are placed in places subject to bad weather, for example those which are envisaged on the roofs of buildings, must allow the passage to air flows in natural circulation not pulsed on relatively important sections without allowing water to enter the interior of buildings during heavy rain.
  • These conditions for stopping bad weather are often more restrictive with regard to powdery snow than with respect to rain. Indeed, heavy rain does not last and it is possible to drain the water that has passed through the grid into a sewer during heavy rain, while snow can pass for several days in a powder form on a roof and accumulate, after passing through the ventilation grille, in a limited area inside the building and melt in this accumulation area, degrading the installations placed below .
  • the present invention provides a ventilation grid which, while leaving free a significant passage of air, repels water projections such as those of heavy rain, and opposes the crossing of sticky or powdery snow.
  • said distance d is between 1 and 5 mm, preferably between 1 and 3 mm
  • the bridges each have, in their part located at the distance from the plate or sheet, at least one molding or protruding longitudinal rib, adapted, on the one hand, to facilitate the lateral rebound of the drops of water which strike the trigger guard and, on the other hand, to stiffen the central part of said trigger guard.
  • the elongated rectangular openings are arranged parallel to one another and delimit between them elongated solid rectangular intervals, or else the rectangular openings are arranged on the plate or sheet metal in a network of parallel lines and columns between they and each have a length of between 20 and 100 mm and a width of between 10 and 20 mm, suitable for limiting the crossing of water and snow projections.
  • the connection part is inclined at each end of the trigger guard in a progressive manner in all directions and is rounded, in the direction of the width of the trigger guard, in the shape of a bow gradually coming to protrude above the plate or sheet.
  • the elongated full intervals between the openings have a hollow groove longitudinally capable of limiting the discharge into the rectangular openings of the water which flows over these solid intervals.
  • the longitudinal molding is preferably formed by pushing out the sheet forming the trigger guard.
  • the ventilation elements for building cover comprising an opening for communication between the interior of the building and the outside atmosphere are characterized in that the opening is closed with respect to water and snow projections from the weather by a ventilation grille of the type described and the bridges of which are oriented longitudinally in the direction of flow of the water.
  • the grid is preferably arranged projecting from an upper sheet fixed to a base plate placed on a roof and the upper sheet carrying the grid is folded down at one of its ends, a short distance from the base plate, to spare a passage for ventilation and evacuation of water by gravity.
  • the invention also relates to the use of such a ventilation grille, arranged in service so that the longitudinal axis of each of the bridges is oriented in the direction of flow by gravity of the water on the plate.
  • FIGS 1 and 2 there is shown a longitudinal ventilation element in sheet metal 1 provided with a row of lateral ventilation openings 2 arranged in pairs in pairs 2a, 2b on either side of a trigger guard 4.
  • These openings in fact start from a cutout 3 of generally rectangular shape formed through the sheet 1 and which is covered frontally by the trigger guard 4 of generally rectangular shape.
  • the trigger guard 4 which has a generally flat surface is placed at a distance d from the general surface la of the sheet which is significantly less than the width l of the openings. This distance d is between 1 and 5 mm, the smallest dimensions making it possible to retain powdery snow well.
  • connection part 4a, 4b is progressively connected to the plate 1 at each of its ends by a connection part 4a, 4b, inclined relative to the plate and which is rounded in the width direction of the bow-shaped bridge 5 , 6 in the zone of connection with the sheet 1.
  • the connection parts 4a, 4b thus start from the end of the cutout 3 with a central crown on the bow part 5, 6 and each continue by projecting from the surface 1a of the sheet 1 by the connection portion to the trigger guard 4 which is progressively less curved in the center, without however completely losing its curved shape which causes the rebound favorable to the evacuation, projections of the water droplets and of the grains powder snow.
  • the bridges 4 and the full rectangular gaps 7 between the openings 3 and the sheet 1 are oriented longitudinally in the direction of flow of the water on the plate 1.
  • the plate 1 is arranged vertically and the bridges 4 are oriented vertically with their longitudinal axis 4e placed lengthwise, as shown in Figure 2, where the ventilation plate 1 itself made of sheet metal is extended in the mass of the sheet metal by a hooking part 8.
  • the bridges 4 are each provided in their part located at the distance d from the surface 1a of the sheet 1, with a longitudinal rib 9 provided at each end with a part tapered in the shape of a bow 10 and 11 to better repel water and powdery snow.
  • the ribs or moldings 9 also serve to make the bridge 4 more rigid and are generally formed directly by pushing back the plate of the trigger guard, or else when the ventilation grid is molded in one piece from plastic material, during the molding of the trigger guard 4.
  • the openings rectangular 3 of the sheet 1, each covered with a trigger guard 4 providing pairs of lateral ventilation passages 2a, 2b, are arranged parallel to each other by providing between them identical rectangular intervals 7 planes and regularly distributed to constitute, for example, a roof ventilation line, as shown in section in Figure 2.
  • a roof ventilation element sometimes also called "cat door", although it no longer allows the passage of cats, consists of an upper sheet 12, preferably of resistant metal corrosion such as zinc and whose edge edges 13 are turned over on three sides to stop the water and channel it into service towards the drain on a front side 13 ′ arranged in service at the bottom.
  • a projecting grid part 14 is formed by pushing back on the upper sheet 12 and has, at its lower part in use, a folded tongue 15 which does not close completely in alignment with the edge on the side 13 ′, in thus leaving a thin passage 16 for the leaks collected by a lower tank 17.
  • a lower sheet or base plate 18, also preferably made of zinc, is formed by folding or stamping with the tray 17 provided with a rear edge 17a.
  • the lower sheet 18 is normally integrated into a roof, for example in the middle of the slates of the roof, where it is applied to the battens of the roof, and it is rigidly connected by any suitable means such as rivets to the sheet upper 12.
  • its planar lateral edges 18a, 18c, arranged in a U with the front edge 18b are applied to the lateral planar edges 13a, 13c of the upper sheet 12 having substantially the same shapes and dimensions in plan.
  • the folded tab 15 is placed just in front of the front edge 17b of the tray 17, leaving the passage 16 open and the pairs of planar edges 13a, 18a and 13c, 18c are made integral by any suitable means such as welding, stapling, etc.
  • the rear plane edge 13b of the upper sheet closes the tray 17 upwards.
  • the ventilation element shown in exploded view in Figure 3 being thus assembled, is mounted inclined in the direction of the slope of a roof panel, so that the water which has accidentally passed through the ventilation grid according to l invention, formed on the projection 14, is collected by the tray 17 and then evacuated by gravity on the front edge 17b of the tray 17, through the passage slot 16 and from there on the flat edge 18b and the elements of blanket, such as slates.
  • the ventilation grille according to the invention which is formed on the projecting part 14 consists of rectangular openings (see the openings 3 in FIG. 2) formed by pushing out the rectangular trigger guard 4 delimited between two parallel slots forming the long parallel side faces 4c and 4d of the trigger guard.
  • the two ends of the trigger guard formed by pushing back remain integral with the sheet 14 by taking a shape of rounded bow which strengthens the attachment of the trigger guard while channeling the water and the snow on hollow grooves 7a (only one groove is shown ) full intervals 7 between the openings 3.
  • the ventilation openings which lead to pairs of lateral passages and which are each covered by a trigger guard 4 are arranged on the projecting part 14 of the upper sheet 1 according to a network.
  • the network is made up according to figure 3 of three parallel lines of eight openings or of eight columns of three openings.
  • the openings 3 generally have a length of between 20 and 100 mm and a width of between 10 and 20 mm.
  • the component parts of the ventilation elements such as that shown in Figure 3, can be made of metal sheet (zinc, aluminum, leaded or unleaded stainless steel, copper, etc.) but also in plastic molding and other material resistant to corrosion, solar radiation and extreme temperature variations in an environment liable to be exposed to the sun (-30, -40 to + 150 ° C).
