Definitions

  • the invention concerns a ventilation appliance comprising at least two angle-formed, vertical groups of louvre-element plates in alternately opposed arrangement, both longitudinal edges of each louvre element being provided with a hook-shaped, back-fold formation, both formations being located on the same face of the louvre element and in staggered opposition to those of the adjacent element whereby the internal protrusion of the formations causes a zig-zag pattern of the through-flowing air.
  • the aim of the invention is to eliminate these disadvantages and to ensure maximum water removal without detriment to the airflow capacity.
  • the invention is thus typified in that the vertical louvre elements have a straight section and are arranged in staggered opposition, formed in groups. Each adjacent group gives rise to an equal unrestricted air passage, whilst the hook-shaped edge formations, each folded inward in the same direction, ensure that the entering airflow is led through the louvre elements with maximum streamlining, whereby the turbulence is kept to a minimum and maximum airflow capacity is assured. Due to the zig-zag path of the main air through-flow the water droplets carried in the airstream will be separated out onto the outer bends by the relatively high centrifugal forces. In this way the optimal conditions are achieved for the apparently conflicting requirements of maximum ventilation coupled with maximum possible weather-proofing.
  • Parts 103 and 104 form a drainage channel for accumulated water droplets, which are separated out onto part 100 of the louvre by centrifugal forces.
  • Figure 3 is a partial longitudinal section through a ventilation appliance provided with louvres according to the invention, whereby a group 107 of louvres 90, as applied in figure 2, arranged in staggered opposition, while their backs 100, also staggered, are fixed by means of a rivet and/or spot-welding 110.
  • the louvres 90 of group 107 form together a defined zig-zag pattern which is caused by the shape of parts 103 and 104 thus creating an optimal passage of air.
  • the side 108 of parts 103 and 104 ensures that the separated water droplets are not re-entrained into the airstream 109 in case of turbulence occuring in parts 103 and 104.
  • the parts 103 and 104 of the louvres in group 107 form drainage channels with inlet opening 123 which runs along the longitudinal edges of the louvres 90 in order to collect and drain water droplets which have been separated by the tangential action through airways 111 and deposited on the louvres 90.
  • channels 103 and 104 are connected at the end (underneath) with the bottom plate 112 in order to drain the water to outside.
  • Figure 4 shows a lateral section through the line IV-IV of figure 3.
  • the louvres 90 are fixed to the top plate 113 and bottom plate by means of supports 114 and 115.
  • Bottom plate 112 constructed at an angle of 15°C for draining, has a flat plate-formed part 116 with a channel-shaped part 117 that forms an angle of 105°C with part 116.
  • the side 118 of part 117 ensures that the entrapped water is not driven by wind pressure upward into the space behind it.
  • the side 119 is at an angle of 105°0 with part 116, and ensures effective drainage of the entrapped water droplets.
  • the part 120 situated on the front edge of louvres 90, forms a windbreak which aims to prevent wind-driven up-flow of the entrapped water droplets.
  • the presence of windbreak 120 causes a pocket of still air directly behind part 120.
  • the drainage of the entrapped water droplets is accelerated by the dynamic pressure from outside (121).
  • windbreak 120 combined with side 119 forms a drain 122 which can be connected into a central drain if necessary.
  • Figurs 5 shows a partial longitudinal section through a ventilation appliance provided with louvres as according to the invention as in figure 3, but including a third louvrs 90 with a hook-shaped back-fold formation on one longitudinal sdge 103 and at the same, time fixed by the backs 100 by means of a rivet and/or spot welding 110.
  • a ventilation appliance squipped with louvres as in figure 5 is primarily completely resistant to extreme weather conditions.
  • the louvres can also be extruded or manufactured in another suitable manner, and furthermore in any suitable material.
  • the louvres can sdditionally be made out of plastic sheeting.
