Definitions

  • This invention relates to a device intended for auto- matic ventilation of buildings, which comprises an elongated cap extending along a part of a roof of a building and having openings for exhausting waist air from the interior of the building.
  • a primary object of the invention is to provide a ventilating device that, without the help of fans or other energy demanding means, accomplishes an improved ventilation in average. This should take place not only by a general enlargement of the total cross-section area of open air outlets in a roof, but also by utilising the kinetic energy of the wind in a purposeful way.
  • Another object is to provide a ventilating device that does not demand the making of holes in the large-faced sheet or flake-shaped parts of a roof extending between the ridge and the eaves.
  • Another object of the invention is to provide a ventilating device which enables the designing of an aesthetically attractive roof while simultaneously facilitating the connection of such roofings as roofing tile and profiled sheets, respectively, to the ridge of the roof.
  • the invention also aims at creating a ventilating device that not only can attain a strong out- flow of exhaust air by means of the wind load, but also an automatic feed of supply air to the interior of the building, likewise only by means of a wind load. It is also an object of the invention to provide a ventilating device which is con- structionally simple and thereby cheap to manufacture and which furthermore may be installed in buildings during erection as well as afterwards.
  • the invention is based on the understanding that the lowest air-pressure prevails where the flow velocity of the air is highest.
  • the flow velocity of passing air on buildings is in average highest in the immediate proximity of the highly loca- ted parts of the roof, in particular the ridge, in case there is one, in all essentials independent of the prevailing wind direction.
  • the ventilating device according to the invention is provided with a bottom part which is narrower than the upper, arched cover sheet, whereby upper portions of e.g., roofing tile or profiled roofing sheet, may in an advantageous way be pushed in under and covered by parts of the cover sheet.
  • a ridge cap with the same function, i.e. with the ability to cover upper portions of roofings, is previ- ously known earlier by US 4 322 924, but in this case the ridge cap has no ventilating effect at all.
  • SE 7909311-8 describes a roof ventilator having upwardly opening outlet openings.
  • these roofs consist of roof on bigger industrial buildings.
  • FIG 1 is a perspective, exploded view showing a ventilating device according to the invention mounted on a ridge
  • Fig 2 is an enlarged cross-section through the device according to figure 1
  • Fig 3 is a schematic, first cross-section showing an alternative embodiment of the device.
  • Fig 4 is a second cross-section, axially separated from the first section according to figure 3, that illustrates another section of the same device.
  • the device shown in figure 1 includes an elongate cap generally designated 1 which extends along the ridge of a roof 2.
  • the main part of this roof is covered with a roofing which is exemplified in the form of roofing tiles 3.
  • the cap 1 extends along the entire length of the ridge, although only a limited section of the same is visualised in figure 1.
  • the cap comprises an upper part 5 which is in the form of an arched plate or sheet, i.e. a sheet having curved, e.g. circular arc-shaped cross-section shape.
  • the central, apex-like portion of the sheet that is highest located in the mounted condition is designated 6.
  • a plurality of long narrow, longitudinal slits 7 are provided, located in a line after each other in the example. These slit openings 7 are separated from each other by means of transversal material por- tions 8.
  • the cover sheet 5 as well as the bottom part 4 may be made either of sheet metal or of plastic_.
  • the slit openings 7 may have a width within the range of 20-50, suitably 25-40 mm, while the length may vary most considerably.
  • the slit may be continuous, i.e. extend along the entire length of the upper part.
  • the upper part is composed of two partial sheets separated by the slit, which sheets are united in a suitable way.
  • In the bottom part 4 of the cap at least one hole 9 is recessed to receive the upper part of a tube 10 through which waste air from the interior of the building may pass out in the open air, more precisely through the slit openings 7 in the upper part 5.
  • the cap composed of the bottom part 4 and the upper part 5, is in all essentials outwardly closed.
  • the lower and upper parts together with suitable end portions form a housing to the interior of which waste air may be led in through the exhaustion pipe 10 and then be led out through the slit openings 7.
  • the bottom part 4 comprises a cross-section-wise V-shaped bottom 11 which may be connected to and centred on the ridge, and which is connected to two upwardly projecting side walls 12. Furthermore, from the upper edge of each such sidewall a flange 13 extends, oriented at an angle to the sidewall. The angle between the individual sidewall and the appurtenant flange may vary, although advantageously attain 90°.
  • the long-side edges 14 of the cover plate 5 are snap-in fastened along the free long-side edges of the flanges 13 and cover these. As may be clearly seen in figure 2, the distance between the free long-side edges 14 of the cover plate 5 is larger than the distance between the upper edges 15 (or corners) of the side walls 12.
  • a number of axially separated head arches 19 are arranged within the cap having the purpose of supporting the cover sheet and of serving as a fastener therefor.
  • a number of clip elements 20 may be attached under- neath the cover plate, e.g. by means of blind rivets. These elements may be snap- in fastened on the arch to either keep the cover sheet in position by themselves or enforce the retention which exists by means of the clip connection along the long- side edges of the sheet.
  • the individual arch 19 has two legs 21 that may be anchored on the roof by angled feet, e.g. by means of screws 22, which simultaneously serve to anchor the bottom 11 against the roof.
  • FIG. 3 schematically illustrates an alternative embodiment of the invention which not only permits exhaustion of waste air, but also feed of supply air to the interior of the building.
  • a partition 23 separates an upper cavity 24, positioned immediately under the cover sheet 5, from a lower cavity 25 in the bottom part of the cap.
  • a waste-air pipe 10 which is shown in a given section along the length extension of the ridge in figure 3, leads to the upper cavity 24.
  • a conduit in the shape of a tube 27 for supply air mounted in another section along the ridge opens to the lower cavity 25, as is shown in figure 4.
  • the individual flap 29 is articulatedly connected at an upper edge to a part of the side wall surrounding the side opening 28 in order to, on one hand, automatically turn to a pendent and closing position by its own weight as long as the effect of the wind is insignificant or non-existent, and, on the other hand, be turned inwardly to an opening position when it is effected by marked wind load.
  • a fundamental advantage of the invention is that it automatically utilises the energy contained in the occurring winds in order amplify or optimise the natural draught action that is always guaranteed by means of the upwardly open exhaustion pipe or pipes that are connected with the ridge cap.
  • the requisite outlet openings in the ridge cap extend along a great length, the total cross-section area becomes very large in comparison with the outlet area of a single tube, whereby the total driving power that is obtained by the negative air-pressure in connection with the slit openings becomes marked.
  • the construction according to the invention makes every making of holes in the large faces of the roof unnecessary. For the observer the ventilating device is therefore masked in an aesthetically attractive way in the exemplified ridge-covering construction.
  • the invention is particularly advantageous in the embodiment shown in figures 3 and 4, in which not only waste-air exhaustion, but also supply-air feed is attained in an automatic way.
  • the invention is not solely restricted to the embodiments described above and shown in the drawings.
  • the embodiment shown, in which the detachable mounting of the cover sheet permits access to the interior of the cap is preferred.
  • the bottom construction of the bottom part may be modified in various ways with the purpose of simplifying the application of the cap on roofs having different roof falls. Though it is preferred to place the cap according to the invention in the ridges in case those exist, it is also feasible to apply the same in connection with other, preferably highly located roof parts.
