Abstract

An arrangement for securing nibless tiles on a roof provides spaced-apart pegs (14, 16) formed integrally with a mounting (2) of moulded plastic adapted for use with a conventional wooden batten (8) or in a modified arrangement spaced-apart pegs (14a, 16a) are integrally moulded with a plastics batten (30). In use, complementary apertures of tiles fixed on a roof are force fit on the pegs (14, 16 or 14a, 16a) whereby the tiles are positively affixed to the roof.

Description

This invention is concerned with improvements in or relating to a roof structure and tile mountings included therein, in particular a roof structure according to the preamble of claim 1.
Conventionally, concrete and clay roof tiles have adequate provision for enabling the hanging of the tiles on a roof. For example, such tiles are provided with hanging nibs which, in use, are hung on the battens of the roof structure.
Some plain tiles as herein defined are not provided with conventional hanging nibs and are usually fastened to the battens using nails for which purpose one or more apertures are normally provided, i.e. pre-punched, through headlap portions of the tiles. It will be readily appreciated that while the hanging nibs of conventional tiles enable the accurate positioning lengthwise of a roof of such tiles, uniformity in laying tiles without a hanging nib is a hit-and-miss affair.
The disclosure of FR-A-2461072 relates to an arrangement for securing corrugated panels or shakes to a roof in overlapping relationship with the arrangement comprising a preformed metal batten adapted in use to accommodate an upper end portion of an associated panel or shake. Spiked portions formed integrally with said battens and upstanding therefrom pierce like panels or shakes extending in overlapping relationship to secure said panels or shakes on a roof.
An arrangement as proposed in FR-A-2461072 cannot be adapted for use with clay or concrete tiles because the batten spikes would damage the tiles rather than pierce them.
FR-A-1 382 637 discloses a roof structure in which plastic tiles are provided with perforated ribs. Pegs extending parallel to the plane of the roof structure are provided on tile battens to engage the perforations in a push-fit relationship. Such an arrangement is not suitable for clay and concrete tiles.
The present invention seeks to overcome or at least mitigate the shortcomings met hitherto in hanging concrete or clay tiles without hanging nibs or equivalent provision. Thus, the present invention conveniently provides a roof structure comprising a mounting for a tile, wherein the mounting comprises tile engaging means upstanding from tile battens and provided by spaced-apart pegs, said pegs being received, in use, in a push-fit relationship within associated apertures formed in a tile mounted on said mounting, characterised in that said pegs extend normally, or substantially so, to the plane of the roof structure.
Conveniently, the spaced-apart pegs are provided on a support adapted for use with a conventional wooden tile batten wherein the support may conveniently be provided by a unitary moulding with the pegs formed integrally therewith.
Preferably the pegs are of rounded cross-section or substantially so and the moulding is formed from a plastics material, preferably polyethylene.
In a modified arrangement the spaced-apart pegs may conveniently be provided on a tile batten of mouldable material.
Conveniently, in the modified arrangement the pegs are moulded integrally with the tile batten and preferably there are at least two such spaced-apart pegs of rounded cross-section or substantially so.
Conveniently the tile batten is formed from a plastics material, preferably polyethylene.
The present invention also conveniently provides a method of tiling a roof comprising the steps of:

a) providing on or associated with the tile battens of a roof a series of tile engaging means provided by spaced-apart pegs and,
b) tiling the roof with tiles, by mounting said tiles on associated ones of the spaced-apart pegs,
whereby the tiles are retained on the roof,
characterised in that said pegs extend normally, or substantially so, in use to a roof on which the tile battens are affixed and said tiles are provided with apertures which enable the mounting of the tiles onto said pegs in a force-fit relationship.

There now follows by way of example of the invention a detailed description of a tile mounting and a modified version thereof together with a novel method of tiling a roof which description is to be read with reference to the accompanying drawings in which:

Figure 1 is an exploded perspective view of a first mounting; and
Figure 2 is a diagrammatic perspective view of part of a modified mounting.

Difficulties met hitherto in attaching plain roof tiles without hanging nibs to roofs are overcome by the present invention which provides a novel roof structure comprising a tile mounting 2 by which tiles, not shown, may be secured to a roof.
The mounting 2 is a unitary moulding of polyethylene or the like plastics material and comprises a hook portion 4 adapted in use to latch over the hanging surface 6 of a batten 8, see Figure 1.
Apertured bosses 10 are provided in the mounting 2 to facilitate the fixing of the mounting 2 to the batten 8 using two nails 12 as shown in Figure 1.
The mounting 2 further comprises tile engaging means provided by spaced-apart pegs 14 and 16 of rounded cross-section or substantially so, see Figure 1.
As with any typical plastics moulding, the mounting 2 is provided with strengthening ribs 20, 22, 23 and 24 as shown in Figure 1.
In tiling a roof according to a method of the present invention using conventional wooden battens 8, mountings 2 are fixed by nails 12 to the battens 8 at spaced intervals therealong to provide a series of pairs of upstanding spaced-apart pegs 14 and 16 which extend normally, or substantially so, to the roof on which the battens 8 are affixed.
Tiles are thereafter affixed to the roof by mounting successive tiles on associated ones of the pairs of pegs 14 and 16, the tiles each having complementary apertures which are a force-fit over said pegs 14 and 16 whereby the tiles are positively affixed to the roof.
In a modified mounting provided by the invention, a pair of pegs 14a and 16a are integrally moulded together with a plastics batten 30, see Figure 2. In use, the modified battens 30 are utilised for tiling a roof by a method which is essentially the same as that hereinbefore described with reference to the batten and mountings of Figure 1, in that the battens 30 are fixed to a roof in conventional manner such that the pegs 14a and 16a extend normally, or substantially so, to the roof on which the battens 30 are affixed.

Claims

A roof structure comprising a mounting (2) for a tile, wherein the mounting comprises tile engaging means upstanding from tile battens (8,30) and provided by spaced-apart pegs (14,16,14a,16a), said pegs being received, in use, in a push-fit relationship within associated apertures formed in a tile mounted on said mounting, characterised in that said pegs (14,16,14',16') extend normally, or substantially so, to the plane of the roof structure.
