Definitions

  • This invention is concerned with improvements in a roof ventilator and is particularly concerned with a covert ventilator for pitched tiled roofs.
  • roof ventilators are disclosed in DE-U 93 09 676.3, see figures 1 and 2, GB 21 99 860, see Figures 17 and 22, GB 22 62 295, see Figure 4, GB 22 79 675, see Figure 4, GB 22 85 817, see Figure 2, DE-U 93 08 401, see Figure 3b and EP 0 663 487, see Figure 5.
  • One of the main disadvantages of these and other prior art ventilators resides in their method of manufacture in that they are usually comprised of several pre-formed pieces of plastics material which are joined together by a suitable epoxy adhesive. Because the ventilators are formed in this way they are susceptible to deterioration, at the sealed joints between the pre-formed pieces thereof. This in turn causes the ingress of rainwater to the underside of the tiles on a roof with the result that the fabric of the dwelling may be harmed.
  • ventilators include upwardly facing grille members for facilitating the ventilation of the underside of the tile and roof space, see GB 2199860 and GbM 9308401. Such arrangements are susceptible to internal blockage due to excess detritus collecting within the ventilator.
  • Other ventilators see DE-U 93 09 676. GB 22 62 295 and
  • EP 0 663 487 are provided with elongate ventilation apertures at a toe end portion of the ventilator unit; however, no provision is made for preventing the ingress of small mammals and birds or driven rain and snow to the inside of the ventilator unit. This may be particularly deleterious in inclement weather conditions when driven snow may pack into the ventilator and interfere with its efficiency.
  • the present invention seeks to obviate or mitigate the drawbacks of prior art ventilators and thus provides a roof ventilator of hollow configuration in use comprising an upper wall of shape complementary to tiles with which the ventilator is used and a lower wall hingedly connected thereto and spaced therefrom the ventilator being formed as a planar configuration in which the upper and lower walls are disposed in the same plane, characterised in that the lower wall is provided with attachment means to facilitate the attachment of a tile blank element to the lower wall.
  • the upper and lower walls are hingedly connected by a flexible web, which is provided between the upper and lower walls.
  • the flexible web is formed integrally with the upper and lower walls as a unitary moulding of plastics material, viz polypropylene.
  • the lower wall is provided with an aperture to facilitate in use the ventilation of a roof on which the ventilator is used.
  • the upper and lower walls are provided with mutually aligned catch members which, when the upper wall is hingedly closed upon the lower wall to form the hollow configuration in use, enable the two walls to be fixedly secured together.
  • the upper and lower walls have baffle elements formed thereon which baffle elements, when the upper wall is hingedly closed upon the lower wall in use, lie between the two walls to prevent the ingress, in use, of detritus and large insects.
  • the present invention also provides a method of ventilating a roof comprising the steps of:
  • the present invention provides a ventilator unit that does not rely on the durability of adhesives used for joining separate parts of a ventilator together but provides a hinged unit that clips together in a closed box-like configuration.
  • the present invention thus comprises a roof ventilator unit 10 provided by a unitary moulding of polypropylene.
  • the unit 10, see Figure 1 generally comprises a shallow tray 12 and a hinged lid 14 providing in use a box like structure as shown in Figure 2.
  • the tray 12 comprises a lower wall 13 and upstanding from the lower wall 13 are left and right side walls 16 and 18 respectively and a rear wall 20.
  • the tray 12 is open at its forward end portion 22 for a purpose to be made clear hereinafter.
  • the lower wall 13 is provided with an elongate aperture 24 bounded by an upstanding wall 26 of an elongate downpipe 28 that depends below the lower wall 13, see Figures 8 and 9.
  • the unit 10 is provided with two memorid rows of integrally formed baffle elements 32 upstanding from said wall 13. Rearwardly of said baffle elements 32, see Figure 1, the wall 13 is provided with four equi-spaced batten bearers 34.
  • the wall 13 is provided with two pairs of elongate nailing bosses 36.
  • the unit 10 is also provided with strengthening and spacing mid-wall elements 38 and 40 upstanding from the wall 13 and extending longitudinally therealong, see Figure 1.
  • the wall 13 also includes a series of snap-fit protuberances 42 formed integrally therewith towards its forward end portion 22, only one such protuberance 42 being shown in Figure 1 and the purpose of which will be explained herinafter.
  • the lower wall 13 is also provided with aligned ribs 44, 44a and 44b depending from an underside thereof for facilitating, in use, the ease with which the unit 10 may be located against a roof batten during its placement on a roof.
  • the hinged lid 14 comprises an upper wall 52 of the unit 10 which wall, see Figure 1, is provided with a row of baffle elements 54 and spaced nail housings 56a, 56b, 56c and 56d upstanding from the wall 52 as seen in Figure 1.
  • the lid 14 also comprises two latch elements 58 and 60 at left and right hand sides thereof respectively, the purpose of which will be made clear herinafter.
  • the lid 14 of the unit 10 is integrally formed with the tray 12 as a unitary moulding of polypropylene as aforesaid, the lid 14 being joined to the tray 12 by a flexible web 62, see Figure 8.
  • a tiler prepares a roof by laying a row of tiles T, and attaches by tacking or nailing cut back underlay portion 70 to the next in line batten 72 above a ventilator aperture formed in the roof structure, see Figure 3.
  • a plain tile underlay seal 74 is then positioned as shown in Figure 4.
  • the tiler next positons an open form unit 10 on the roof structure with the ribs 44, 44a and 44b in locating engagement with an upper edge 76 of a batten 73 i.e. the batten next below the batten 72 of the roof structure. He then attaches the unit 10 to the roof structure using felt tacks 78 and nails 80 as shown in Figures 5 and 6.
  • the unit 10 has a plain tile blank element 75 pre-attached thereto by means of the snap-fit protuberances 42.
  • the tiler then folds the hinged lid 14 to overlie the tray 12 and causes the latch elements 58 and 60 to be brought into locking engagement with associated detents 68 and 69 respectively provided in the side wall 16 and 18 of the tray 12, see Figure 5.
  • the latch elements 58 and 60 and the detents 68 and 69 being aligned catch members enable the two walls (52, 13) to be fixedly secured together.
  • clip portions 38a and 40a located on an underside of the lid 14, see Figures 1 and 2 are brought into holding engagement with their respective mid-wall elements 38 and 40, see Figure 6.
  • the ventilator unit 10 is thus reduced to its box-like structure as shown in Figures 2 and 6 in which the baffle elements 54 of the lid 14 lie between the two rows of baffle elements 32, see Figure 9, and the nail housings 56a, 56b, 56c and 56d overlie and surround the nailing bosses 36a, 36b, 36c and 36d.
  • the baffle elements 54 and 32 provide preventative means against the ingress of small birds, mammals and large insects to the roof space through an elongate aperture 82, defined between toe end portions 84 and 86 of the tray 12 and lid 14, and through the aperture 24 provided in the lower wall of the tray 12.
  • the nail housings 56a, 56b, 56c and 56d shelter and provide barriers against the ingress of driven rain and derivatives to the nail bosses 36a, 36b, 36c and 36d respectively.
  • the ventilator unit described herein envisages the hinged connection being between the upper and lower walls of the unit at the upper end portions thereof.
  • the unit may comprise more than one hinged walls and the hinged connections may be at the sides or toe portions of the unit.
