Definitions

  • This invention is concerned with improvements to a roof ventilator unit as set forth in the preamble of the accompanying main claim.
  • the filter means in this prior art roof ventilator have the shape of a horizontal portion with a plurality of ventilation slots, one side of this portion being integrally linked to a horizontal securing portion for attaching the roof ventilator unit on the top of the fascia board, and the other side of this ventilation portion being integrally linked to the lower end of upstanding tooth elements so that these tooth elements in use are positioned at a distance to and on the same level as the top of the fascia board, resulting in that the tooth elements by pushing against the roof covering, exert a toppling force on the roof ventilator unit.
  • the invention contemplates a new and improved roof ventilator unit which is characterized by the features in the characterizing portion of the accompanying main claim in order to provide a mutual right position of the anti-ponding strip and the drip skirt and in order to eliminate a toppling force on the roof ventilator unit.
  • the anti-ponding strip is integrally formed with the other portions of the roof ventilator unit, the anti-ponding strip is always joined to the drip skirt in a waterproof way, so that water underneath the roof covering is collected by the anti-ponding strip and is removed by the drip skirt over the fascia board into the roof guttering.
  • the invented roof ventilator unit having the anti-ponding strip integrally formed thereon is cheaper to produce and easier to attach than the prior art roof ventilator unit and a separate anti-ponding strip.
  • the tooth elements of the invented roof ventilator unit in use are positioned substantially straight over the top of the fascia board, so that the tooth elements pressing against the roof covering do not exert a toppling force on the roof ventilator unit.
  • the filter means preferably is an array of pins which depend from the upper edge region of the profiled member in a generally downwards direction towards the fascia board, the pins defining slots therebetween through which birds and flying insects cannot pass.
  • the array of pins is arranged in a double or multiple row, pins in each row being offset to alternate with respect to pins in the other row or rows.
  • Roof ventilator units according to the invention may be formed in predetermined lengths for mutually attaching units end to end, to provide in use an uninterrupted length of ventilation over the length of a fascia board.
  • lengths of roof ventilator unit are adapted to overlap or interenagage at their ends with adjacent roof ventilator units.
  • Interengagement may be provided by a tongue-and-groove arrangement, for example, in which a tongue is formed at the one end of the profiled roof section and a groove is formed at the other end, whereby the tongue of a first ventilator unit is insertable within the groove in a second roof ventilator unit when the said units are arranged in end-to-end relationship.
  • At least the anti-ponding strip is formed at one end with a tongue extending longitudinally of the unit and at the other end with a groove defined between upper and lower lips.
  • the upper surface of the tongue is preferably formed with one or more transversely extending ribs for strengthening purposes and to define a water-drainage duct.
  • the drip skirt portion of the ventilator unit is preferably formed at the tongue end thereof with a transversely extending channel into which the duct opens, to convey water in the duct into the roof guttering, and in which engages a flange formed beneath the drip skirt portion of the adjacent roof ventilator unit at the groove end thereof when the said ventilator units are interengaged in end-to-end end relationship.
  • At least the flanged end region of the drip skirt portion may be resiliently deformable about a longitudinal axis of flexion to allow it to be lifted, for the purpose of positioning the flange in the channel of the adjacent ventilator unit, after interengagement of the respective tongue and groove.
  • the flexible upstanding tooth elements which constitute a filler element to engage the underside of overlying tiles or slates to exclude for example birds from the space between the tiles or slates and the underlay, are preferably all of substantially the same height, rather than being pre-formed to match the under-side of a particular design of tile.
  • the length is sufficient to reach from the upper side of the profiled member to the highest point on the under-side of any available tile or slate, the gap therebetween will be substantially covered and any undulations in the underside of the tile or slate will be accommodated by the flexibility of the tooth elements and hence the angle which they are constrained to adapt, according to the shape of the tile and the pitch angle of the roof.
  • individual tooth elements can be used to maintain a tile-engaging clip in position, for the purpose of securing said tile to the eaves.
  • a clip may be formed to engage in the drip edge of a tile, the clip including a downwardly-directed limb including a slot defined by angled opposed gripping members between which a selected tooth element can be inserted from below and passed therethrough until under tension, the members acting together to clamp on the tooth element on the application of any tension in the reverse direction, whereby the clip and hence the tile are effectively locked in position.
  • Ventilator units according to the invention may be formed, for example by moulding, from a polyolefin plastics material, preferably a polypropylene or polyethylene.
  • a ventilator unit is shown generally at 10 and includes an elongate profiled member 11 having an arcuate cross section (see Figure 3), the upper edge region of which is formed integrally with an anti-ponding strip 12 and the lower edge region of which terminates in a drip skirt 13.
  • the thickness of the anti-ponding strip is less than that of the profiled member 11, such that the former is flexible for accommodation of different pitch angles of roofs, while retaining sufficient rigidity to support the roofing felt without distortion or depression.
  • a longitudinal zone of flexion is provided to permit the profiled member to bend relative to the anti-ponding strip, for example for inter-engaging ventilator units in end-to-end relationship (see Figure 6).
  • a row of upstanding comb-like tooth elements 14 are integrally formed at the upper rear edge of the profiled member 11 and support brackets 15 are formed below the profiled member at intervals, the brackets in cluding surfaces 16 and 17 for engaging a fascia board 28.
  • brackets Preferably brackets have apertures 18 terminating at their upper ends in slots 19 having a raised edge formation 20, for the purpose of receiving the heads of nails or screws for fixing to the fascia board.
  • a double row of alternating pins 21 is also formed integrally with the underside of the profiled member 11, the pins depending in a generally downwards direction towards the surface 16.
  • the right-hand end (in Figure 1) of the anti-ponding strip 12 is formed with a longitudinally-extending tongue 22 having lateral ribs 23, and the water drainage ducts formed thereby lead to a lateral channels 24 formed at the righ-hand end of the drip skirt 13.
  • the left-hand end of the drip skirt 13 is formed with a depending flange 27 which can engage with the channel 24 of the said adjacent ventilator unit (see Figures 6b and 6c).
  • a fascia board 28 is indicated in cross-section and attached thereto is shown a support bracket 15 of a ventilator unit.
  • the concave arcuate surface of the profiled member 11 of this ventilator unit is held spaced from the fascia board and generally bounding the front upper edge 29 thereof. It is seen in Figure 4a how, with a slate-covered roof set at a steep pitch angle, the teeth 14 are directed upwardly to engage the underside of the slates whereas, with a tiled roof set at a shallow pitch angle and as seen in Figure 4b, the teeth are directed downwardly.
  • the teeth 14 are bent to various extents with respect to one another against the tile 31, the theeth thus barring the access along the undersides of the tiles.
  • the drip skirt 13 terminates above the bottom of the eaves guttering 30.
  • FIG. 5 illustrates the use of a tile clip secured to the fascia board 28 via one of the teeth 14 of the ventilator unit 10.
  • the drainage edge of a tile 31 is engaged by a pre-formed metallic clip 32 including uni-directional self-locking gripper jaws 33 between which is passed a tooth 14 of the filler element.
