Definitions

  • the invention relates to an inlet or outlet grid for arrangement in a rectangular or square opening which is in communication with an air feed duct system, which grid is provided with parallel grid blades.
  • the air duct systems referred to in the preamble are mostly used for ventilation systems in buildings where the intake and outlet debouch into an outside wall of the relevant building.
  • the usually rectangular or square openings in the outside wall have to be screened off by a grid.
  • the making and fitting of such a grid is relatively complicated because of the lack of standard dimensions so that it is scarcely or not possible to manufacture the grids in accordance with uniform dimensioning.
  • the invention has for its object to obviate the above stated drawback and seeks to provide a grid which, in addition to having a construction of relatively few different compo­nents, is easy to assemble with regard to fitting.
  • each blade is a strip-like profile having means extending along the edges for receiving a pin-like abutment that is directed perpendicularly to a wall of a side profile bounding the grid.
  • the side profile has only to be provided with pin-like members, either integrally cast or placed later, which fit into the recesses arranged in the continuous profile so that the blade profile can be sawn off at any desired length. Assembly is limited to insertion of the different elements into each other.
  • a framework which according to the invention preferably consists of four similar, substantially L-shaped profiles.
  • the grid is provided with a wire mesh extending between the legs of the L-shaped edge profiles and situated adjacent to the grid blades.
  • the wire mesh is hereby automatically enclos­ed between the edge profiles and the grid blades.
  • the invention proposes to embody the edge portion thereof facing away from the wire mesh with a curl of U-shaped cross-section, whereby the corner connection is effected by an L-shaped coupling member, the legs of which fit into the U-shaped curl.
  • the inlet or outlet grid shown in fig. 1 for an air duct consists substantially of a framework 1 built up of side profiles 2 and bottom and top profiles 3. Arranged between the side or edge profiles are a number of parallel grid blades 4 which have a strip-like shape and which display along the front and rear edges 5, 6 a receiving means 7, the function of which is further explained below.
  • the edge profiles 2 are substantially L-shaped whereby the long leg 8, see fig. 2, is provided with a pattern of pressed-out portions 9 for receiving pin-like abutment means.
  • the short leg 10 of the L-shaped edge profile serves to support a wire mesh 11 to be arranged between the grid blades 4 and that leg, see fig. 1.
  • the other end portion of the L-­shaped edge profile 2 is curled round into a U-shape, see 12, and this curled edge strip serves for fixing of the ends of the edge profiles sawn to length. Fixing is carried out by a separate L-shaped coupling member 13 provided with two mutually perpendicular legs 14 which can be received into the inside of the U-shaped edge strip 12 of the profile 2. Further fixing can take place in any suitable manner, for instance by spot welding and the like.
  • the above mentioned pin-like abutments are formed in the embodiment according to fig.
  • the manufacture of the present grid is very simple because the fitter only has to shorten the grid blades 4 to length, start­ing from a long strip of profile material 4.
  • the edge profiles 2 and 3 are shortened to length, and the grid can be assembled.
  • the grid blades 4 can be arranged between the edge strips 2 beforehand by means of the screw bolts 15 or later after the forming of the framework from the profiles 2 and 3.
  • Fig. 3 shows an alternative embodiment whereby the pin-­like abutment means are fixed beforehand to the edge profiles 2 so that the grid blade profiles 4 can be pushed onto them.
  • the pins can be of random type and can for instance be welded, riveted, integrally cast etc. onto the outer wall of the edge strip 2.
  • the profile strip 4 can be manufactured from plate material whereby the edge strips are curled, whereby a slight­ly resilient effect can be exerted on the pin-like abutments 15.
