Abstract

The invention relates to a ridge tile/vent 1 of moulded synthetics plastics material incorporating an integral, tubular extension 6 extending inwardly from an aperture 7 passing through the tile/vent, the aperture 7 being provided with a protective grill 8. Use For venting soil or drainage pipe outlets. <IMAGE>

Description

SPECIFICATION Tiles or vents This invention relates to a ridge tile/vent for use in connection with soil and/or drainage pipe outlet vents of buildings.

Conventional venting means consist of a pipe extending upwardly to a terminal pipe end located at a level above at least some portion of a roof, the pipe being located either externally of the building or internally of the building, and it is with respect to the latter arrangement that the invention is particularly concerned.

Internal systems require a terminal pipe end to pass through the roof and in the case of a tiled, pitched roof for instance, this necessitates a first plumbing operation in the form of fixing of the main soil stack before the roof can be tiled. During tiling it is necessary to aperture a tile for the passage of the terminal pipe end and for the aperture to be sealed with flashing to avoid ingress of water, whereupon the remaining roof constructional operations are completed, after which final plumbing operations are effected to connect this stack to the discharge system proper. It is necessary of course, for protection against birds, leaves or general ingress of debris, to provide the end of the terminal pipe end with a grating, grill etc.

According to the present invention, there is provided a ridge tile/vent of moulded synthetic plastics material, incorporating an integral, tubular extension extending inwardly from an aperture passing through the tile/vent, the aperture being provided with a protective grill.

Thus, with the ridge tile/vent according to the present invention, constructed to standard shape and/or of standard dimensions, e.g. of half-round, third-round, or Delta configuration, the tile/vent can be fitted as a dummy tile or false tile along the ridge of a building so that with a soil and/or drainage pipe outlet connected to the tubular extension - with the latter constituting a spigot or a socket - the pipe end terminates generally at roof level, in contrast to the conventional upward projections from a roof, thus improving the appearance of the building, while furthermore the tile/vent is maintenance free in that the use of conventional lead flashings is avoided.

Also from the aesthetic viewpoint, it is desirable to mould the ridge tile/vent in a suitable colour, so that it blends in with conventional ridge tiles. Additionally, the plumbing operations may be carried out during a single visit to the building involved, in contrast to the two visits conventionally required, and finally, because plumbing may now be effected after tiling, the plumbers may always work under cover.

Preferably, the tile/vent is moulded with spacedapart inner and outer walls separated by connecting webs, to provide mortar receiving cavities between the inner and outer walls, and after the tile/vent has been cemented in during normal ridge tile fixing operations, the tubular projection is connected, e.g.

via flexible tubing or by rigid PVC tubing, to a soil and/or drainage pipe.

Preferably, the grill is integrally moulded with the remainder of the ridge tile/verit and conveniently is contiguous with the outer surface of the tile/vent, the grill of course serving principally to prevent the ingress of leaves etc. or access of birds into the ridge tile/vent and thereby obstructing the efficiency of the latter.

The invention will now be described in greater detail, by way of examples, with reference to the accompanying drawings, in which: Figure 1 is a half sectional view, half end view of a first embodiment of ridge tile/vent in accordance with the present invention; Figure 2 is a plan view of Figure 1; Figure 3 corresponds to Figure 1 but shows a second embodiment; Figure 4 is a plan view of Figure 3; Figure 5 corresponds to Figure 1 but shows a third embodiment; and Figure 6 is a plan view of Figure 5.

In all Figures, like reference numerals are employed for like components.

A ridge tile/vent 1 is of synthetic plastics material and is moulded to a standard ridge tile shape. Thus in the embodiment of Figures 1 and 2 the moulding is to half-round shape, in the embodiment of Figures 3 and 4 the moulding is delta-shape, and in the embodiment of Figures 5 and 6 the moulding is to third-round shape.

Each tile/vent 1 comprises an outer wall 2 spaced from an inner wall 3, the walls 2 and 3 being connected together at opposite edges of the tile/vent 1 in common closure walls 5. Each tile/vent 1 incorporates an integrally moulded tubular extension 6 extending inwardly from a circular aperture 7 passing through the inner and outer walls 2, 3. At the outer end of the aperture 7 is integrally moulded a grill 8 so as to be contiguous with the outer wall 2.

1. A ridge tile/vent of moulded synthetic plastics material, incorporating an integral, tubular extension extending inwardly from an aperture passing through the tile/vent, the aperture being provided with a protective grill.

2. A ridge tile/vent as claimed in Claim 1, moulded to half-round configuration.

3. A ridge tile/vent as claimed in Claim 1, moulded to third-round configuration.

4. A ridge tile/vent as claimed in Claim 1, moulded to delta configuration.

5. A ridge tile/vent as claimed in any preceding Claim, provided with spaced-apart inner and outer walls separated by connecting webs.

6. A ridge tile/vent as claimed in any preceding Claim, wherein the grill is integrally moulded with the remainder of the ridge tile/vent.

7. A ridge tile/vent as claimed in any preceding Claim, wherein the grill is contiguous with the outer surface of the tile/vent.

8. A ridge tile/vent substantially as hereinbefore described with reference to Figures 1 and 2 of the accompanying drawings.

9. A ridge tile/vent substantially as hereinbefore
