Definitions

  • roof ventilators are disclosed in GB 2199860, see Figures 17 and 22, GB 2262295, see Figure 4, GB 2279675, see Figure 4, GB 2285817, see Figure 2, German GbM 9308401 , see Figure 3b and EP 0663487, 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 GB 2262295 and EP 0663487 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 the prior art ventilators and thus provides a roof ventilator provided by a hollow tile-shaped unit provided with an upper wall of shape complementary to tiles with which the ventilator is used and an apertured lower wall spaced therefrom, the unit comprising an elongate aperture between the upper and lower walls at a toe portion of the unit characterised in that the ventilator comprises a grille member located within the aperture of said unit for limiting the ingress of small mammals and birds, the ventilator also comprising a baffle means located within said unit for limiting the ingress of driven rain and/or snow and large insects to the inside of the unit and the underside of the apertured lower wall.
  • the grille member and the baffle means are integrally formed one with the other.
  • the grille member and the baffle means are conjoined by connecting ribs which, when the grille member and the baffle means are located as aforesaid, extend longitudinally of said unit between the upper and lower walls to add rigidity and strength to the unit.
  • the tile-shaped unit provided by the present invention is preferably formed by rotational moulding from a plastics material, viz. polyethylene or a polypropylene coated polyurethane.
  • the conjoined grille member and baffle means are moulded from a plastics material, e.g. polyvynilchloride (PVC).
  • a plastics material e.g. polyvynilchloride (PVC).
  • the tile-shaped unit is conveniently made from a plastics material, viz. polyethylene or polypropylene coated polyurethane and the pre-formed grille member and baffle means are moulded from a plastics material, viz. polyvynilchloride (PVC).
  • a plastics material viz. polyethylene or polypropylene coated polyurethane
  • PVC polyvynilchloride
  • Figure 1 is a right-hand upper perspective view of the novel roof ventilator
  • Figure 3 is a view in the direction of the arrow III in Figure 1 ;
  • Figure 4 is a view in the direction of the arrow IV in Figure 1 ;
  • Figure 5 is an exploded right-hand upper perspective view with an upper wall of the ventilator removed to reveal the inside of the ventilator;
  • Figures 6 and 7 are views corresponding to Figure 5 showing the interrelationship of parts of the ventilator during the assembly thereof;
  • the present invention provides a roof ventilator 10 which comprises a hollow tile-shaped unit 12 having an upper wall 14 which is of complementary shape to the tiles T with which it is intended to be used, see Figures 1 and 10, and an apertured lower wall 16 spaced from said upper wall, the unit also comprising an elongate aperture 18 between the upper and lower walls 14 and 16 at a toe portion of the ventilator.
  • the tile-shaped unit 12 is rectangular in plan, see Figure 9 and the upper wall 14 thereof has the configuration of a so-called "Roman" type tile having a centre roll portion 30 and two opposite side roll portions 32 and 34 extending from an upper headlap portion 40 to a lower toe portion 41 of the wall 14.
  • the roll portions 32 and 34 are separated from the centre roll portion 30 by intermediate trough portions 36 and 38 respectively, see Figure 1.
  • the upper wall 14 is provided with water channels 42 and 44 extending laterally of the headlap portion 40 and water bars 46 and 48 at the upper extremities of the trough portions 36 and 38 respectively, see Figure 1.
  • the apertured lower wall 16 comprises a central well portion 70 on which is formed a depending cylindrical spigot 72, see Figures 1 , 2, 3, 4, 5, 6. 7 and 8, which, extends from an aperture 17 formed in the wall 16 and which, when the ventilator is in use, may be connected to a soil pipe or any like device, not shown.
  • the baffle means 22 is also shaped to complement the configuration of the aperture 18 formed between the upper and lower walls 14 and 16 and is also an elongate moulded structure provided with a series of four laterally disposed baffles 82 connected together by a series of five strengthening ribs 84 which extend at right angles or substantially so to the baffles 82.
  • the ribs 84 extend longitudinally of the ventilator when the baffle means 22 is assembled therein, see Figure 7.
  • the size of the aperture 18 and the spacings between the bars 80 and the spacings between the baffles 82 are chosen in order that an adequate flow of ventilation air is facilitated between the outside and inside of the roof structure on which the novel ventilator is used. Should any driven rain or snow by-pass the baffles 82, in order to prevent ingress thereof to the underside of the unit 12, an upstanding wall 100 is provided in the well portion 70 partially surrounding the aperture 17, see Figures 5, 6 and 7.
  • the lower wall 16 is also provided with an upwardly extending spigot 102 moulded in its headlap portion, see Figures 5, 6 and 7, which spigot 102 adds strength to the moulded unit and also facilitates the fastening of the unit to a roof batten by appropriate means, e.g. a nail.
  • the novel roof ventilator provided by the invention is manufactured as three separate parts.
  • the tile-shaped unit is formed by a rotational technique from a suitable plastics material, e.g. polyethylene or a polypropylene coated polyurethane.
  • a suitable plastics material e.g. polyethylene or a polypropylene coated polyurethane.
  • the baffle 22 and grille 20 are moulded from a polyvynilchloride material.
  • baffle 22 and grille 20 are then assembled together by inserting the spigot means 92 of the baffle 22 into the housings 90 of the grille 20, see Figure 5.
  • baffle and grille are then offered up to the aperture 18, see Figure 6 whereupon full insertion of the assemblage into the unit 12, see Figure 7, is achieved when keying means (not shown) on the grille 20 becomes engaged in locking engagement with detents (not shown) provided in the inside walls of the unit 12.
  • the roof ventilator of the present invention facilitates the full ventilation of the underside of the tiles or the roof space beneath the tiles while presenting a most aesthetically pleasing roof line. It. will be realised that the colour and surface finish of the ventilator may be chosen to suit the colour and finish to the roof tiles with which it is used.
  • tile-shaped unit is made of polyethylene or polypropylene coated polyurethane, any suitable material which does not suffer from deleterious effects in inclement weather conditions may be used.
  • the grille 20 and baffle means 22 may also be made from any suitable plastics material.
  • roof ventilator of the present invention is in the main manufactured as a single unit by rotational moulding, it will not be susceptible to the deleterious effects presently suffered by premoulded units which are secured together by sealants of various kinds.
  • the ventilator described herein by way of example of the invention has a shape and configuration akin to a so-called "Roman" type tile
  • the ventilators provided by this invention may be of suitable shape and configuration to match the roof tiles with which they are intended to be used.
