The ventilator has a cover 34 mounted on the upper face of the body 10 to overlie the aperture, the cover 34, together with lips around the aperture, being adapted to prevent rainwater, which may enter the cover through grilles therein, from passing into the aperture. On its lower face the body 10 provides a downwardly extending peripheral flange(38) around the aperture. In use, the flange 38 projects through the roof felt and has a pair of resiliently deformable lugs. To ventilate internal areas of the building other than the roof space, the ventilator can be connected with any appropriate duct or pipe by way of a flexible coupling (44). The latter has an annular projecting rib (46) at one circular end, the latter being manually deformed when located within the flange (38) to be a snap-fit therein, by the rib 46 resiliently deforming the lugs in the flange (38).

Description

Ventilators for Roofs This invention relates to a ventilator for use on a roof, particularly a tile or slate roof, the ventilator being capable of ventilating the roof space or ventilating a specific interior area of a building, for example by way of an extraction fan duct or a soil pipe.
According to the present invention there is provided a ventilator for use on a roof, the ventilator comprising a body part adapted to be laid on a roof and associate with roofing components, the body part having a through aperture, and a cover part for mounting on the body part whereby to overlie the aperture, the cover part providing a through air passage to the aperture but preventing direct access thereto.
Preferably the aperture is elliptical, and may be bounded on one side of the body part, the underside in use, by a peripheral flange. The flange may be provided with resiliently deformable lugs, for example a pair of such lugs at opposed locations on the flange.
Preferably also the aperture is bounded on the upper side of the body part around one edge of the aperture, the upper edge relative to the angle of the roof, with an upstanding peripheral lip. A further upstanding lip may be formed on the upper side of the body part to extend from the aperture lip to a lower location on the body part. The cover part preferably overlies the lips, the latter preventing passage of rainwater past the cover part into the aperture. An upstanding ridge may be provided on the upper side of the body part at a location spaced above the aperture lip and externally of the location of the cover part, whereby to deflect rainwater.
The cover part may have a plurality of profiled clips engageable in respective apertures in the body part at a lower end thereof relative to the angle of the roof, whereby when the clips engage in the apertures, the cover ppt may be effectively pivoted to a closed position over the aperture. The cover part may be adapted at the upper end thereof relative to the angle of the roof to interact with locations on the body part which can receive fittings for fixedly securing the cover part to the body part.
The invention also provides an assembly for ventilating an interior area of a building through a roof of the building, the assembly comprising a ventilator as described in any of the four preceding paragraphs, and a flexible coupling for connecting an internal duct of the building to the ventilator, one end of the coupling being adapted to interact with the aperture in the body part.
Preferably the one end of the coupling is adapted to interact with the peripheral flange extending around the aperture. The coupling may have a substantially circular cross-section, with said one end thereof being manually deformable to locate in the flange. Said one end of the coupling may be profiled to be a snap-fit into the flange by deflection of the resiliently deformable lugs thereof. Means, for example in the form of a ring, may be used to provide additional strength to the profiled end of the coupling.
The other end of the coupling may be profiled to provide for snap-fitting into an additional coupling length.
An embodiment of the present invention will now be described by way of example only, with reference to the accompanying drawings, in which: Fig. 1 is a top view of a ventilator according to the invention; Fig. 2 is a top view with the cover omitted; Fig. 3 is an underneath view of the ventilator of Fig. 1; Fig. 4 is a side view of a flexible coupling for use with the ventilator; and Fig. 5 is a part side view showing the ventilator in use.
Referring to Figs. 1 to 3 of the drawings1 a ventilator for use in a slate or tiled roof comprises a substantially planar main body 10 in which is provided a through aperture 12 of elliptical shape. Relative to a transverse centre line of the body 10, the aperture 12 is formed to one side thereof in a section 14 of the body 10 which is lowermost in use relative to the angle of the roof in which the ventilator is to be laid. An upper section 16 of the body 10, when secured to the roof, has slates or tiles laid thereover. The lower section 14 replaces respective tiles or slates and has other tiles or slates laid up to the sides and lower edge thereof.
As shown in Fig. 2, the aperture 12 is bounded around an upper edge of the uppermost side with an upstanding peripheral lip 18. The ends of the lip 18 are integrally formed with further lip sections 20, upstanding on the body 10 and extending downwardly from the aperture 12. Another lip section 22, upstanding on the body 10, extends between the lower ends of the sections 20, the latter having respective inwardly extending baffles 24 close to the lower ends thereof. A ledge 26 is formed to be upstanding on the body 10 in a spaced relation above the aperture lip 18, and a pair of upstanding bosses 28 are provided at respective sides of the aperture 12 between same and the ledge 26.
At the lower end of the body 10 there are provided three spaced through slots 30 and a through hole 32 below the central one of the slots 30.
A cover 34 (Fig. 1) is provided for mounting on the body 10 whereby to overlie the aperture 12. The cover 34 has substantially the form of an upturned tray of rectangular configuration with an insect grille 36 formed in each of three sides thereof by way of a plurality of parallel, elongate slots. The cover 34 is adapted to locate on the body 10 with the non-grille side uppermost. The lower side edge of the cover 34 is formed with three spaced clips so arranged as to be engageable respectively in the slots 30, the profile of the clips being such that the cover can be mounted on the body 10 and then effectively pivoted to a closed position wherein the cover 34 overlies the aperture 12, the lips 18 - 22, and the bosses 28, the upper end of the cover 34 locating below the lower edge of the ledge 26. The cover 34 is internally profiled at the locations of the bosses 28 whereby fixings in the forms of screws or the like can securely engage through the bosses 28 into the cover 34 to secure the latter to the body 10.
The grilles 36 provide through passages into or out from the aperture 12 to externally of the cover 34 and therefore externally of the roof. The lips 18 22 prevent rainwater which may enter the cover 34 from passing into the aperture 12, while the ledge 26 diverts rainwater from above the cover 34 over the latter and downwardly from the roof.
Referring to Fig. 3, the body 10 provides a downwardly extending peripheral flange 38 around the aperture 12. In use, the flange 38 projects through the roof felt when the latter is cut at the required location, and prevents the felt from falling back across the aperture. The elongate flange 38 has a pair of resiliently deformable lugs 40 formed at each of opposed locations adjacent its lower edge.
When used to ventilate a roof space, the body 10 is positioned on the roof to cooperate with the roof tiles or slates as hereinbefore described, the aperture 12 with the flange 38 providing for communication with the roof space and the cover 34 preventing entry of rainwater or ingress of insects or materials to the roof space. The elliptical or oval shape of the flange 38 is dimensioned whereby to fit between adjacent battens of the roof, effectively regardless of the spacing between the adjacent battens, which is determined by the type of slates or tiles used and the pitch of the roof. For added security, the body 10 can be nailed to the roof through the hole 32 to further prevent the ventilator being inadvertently moved off the roof by the wind.
The ventilator can also be used to ventilate internal areas of the building other than the roof space, for example by way of internal ducting for extraction fans, or by way of soil pipe ventilation. To connect the ventilator with any appropriate duct or pipe, there is provided a flexible coupling 44 (Figs. 4 and 5).
The latter has the form of a plastics tube formed along a section 45 with a bellows configuration to flexibly extend between the location of the duct or pipe and the flange 38 of the ventilator.
At one end, the coupling 44 is formed integrally with an annular/projecting rib 46. To attach to the flange 38, the circular end of the coupling 44 may be manually deformed towards an elliptical shape whereby to locate within the flange 38 and be a snap-fit therein, the rib 46 being pushed passed the lugs 42 which resiliently deform to allow entry of the coupling and then regain their original position to lock over the rib 46. Thereby the coupling 44 can be quickly and easily fitted to the flange 38 and therefore to the ventilator without the use of any other adaptors or clips. If desired however, a plastics ring (not shown) may be provided on the respective end of the coupling 44 beneath the rib 46 whereby to effectively strengthen the latter to ensure non-deformation and therefore prevent accidental release of the coupling 44 from the ventilator.
It is to be appreciated that the coupling 44 may be attached to a ventilator having a through aperture which does not have a downwardly extending peripheral flange.
The other end of the coupling 44 may be secured to the respective duct or soil pipe in any conventional manner. The other end of the coupling 44 is however profiled to have an annular protrusion 48 which can snap-fit into a complementary annular recess in an end of a coupling extension (not shown) if this is required to provide communication between the duct or pipe and the ventilator.
The body 10 is preferably manufactured from UV stabilised durable polypropylene and provides for the required 10,000 mm air flow. The ventilator provides an unobtrusive low profile and is easy and quick to fit.
Because the flange is designed to fit between adjacent battens of any normal spacing, there is no need to cut battens as is often the case with known ventilators. Also there is no need for adaptors or clips to secure the flexible coupling to the ventilator, this being a saving in cost as well as facilitating installation.
Various modifications may be made without departing from the invention. For example the various components may be shaped differently from those described and shown.
Whilst endeavouring in the foregoing specification to draw attention to those features of the invention believed to be of particular importance it should be understood that the Applicant claims protection in respect of any patentable feature or combination of features hereinbefore referred to and/or shown in the drawings whether or not particular emphasis has been placed thereon.
