Abstract

A roof tile having dimensions equivalent to at least twice that of a conventionally sized tile and preferably three times that of a conventionally sized tile, the roof tile having one or more score lines which delineate the roof tile so as to provide the appearance of two or more conventionally sized tiles. Preferably the dimensions of the tile are approximately 265mm by 495mm with a thickness of approximately 8mm and which comprises two score lines.

Description

This invention relates to a roof tile. Roof tiles are well-known. For example, a plain tile comprises a hardened cementitious material having dimensions generally 265mm by 165mm and fixing apertures for enabling nails to secure the tile to a roof batten.

By nature of their size, such tiles present an aesthetic and pleasing finish and in some markets, tiles any larger in size would not be acceptable. On the other hand, it would be desirable to produce tiles which were larger because a considerable cost associated with roofing is the manual labour employed for fixing a plurality of tiles to a roof.

It is an object of the present invention to provide a tile which endeavours to preserve the aesthetic appearance of conventional plain tiles while at the same time reduce considerably the costs associated with the placing of them on a roof structure .

The invention, therefore, provides a roof tile having dimensions equivalent to at least twice that of a conventionally sized tile and preferable three times that of a conventionally sized tile, the roof tile having one or more score lines which delineate the roof tile so as to provide the appearance of two or more conventionally sized tiles.

OPEN TO PU8s ‘C INSPECTION SECTION ^8 AND RULE 23 JNL No '^'S OF /*/^6 k-ββθβ? j Preferably, the score line or lines extend over the edge of opposing sides of the tile so as to give a more authentic appearance of a plurality of tiles.

The invention will be understood in greater detail from the following description of a preferred embodiment thereof given by way of example only and with reference to the accompanying drawings in which: Figure 1 is a perspective view of a roof tile according to the invention; and Figure 2 is a side elevation of the roof tile of Figure 1 of the drawings.

Referring now to the drawings, there is shown a roof tile 10 according to the invention which comprises a cementitious material having dimension approximately 265mm by 495mm with a thickness of approximately 8mm.

As the dimensions of a conventional tile are approximately 265mm by 165mm, the tile 10 essentially has the width of three conventional tiles. The tile 10 has a first pair of opposing sides 11, 12, a second pair of opposing sides 13, 14,- an upper face 15 and a lower face 16. Each side 11, 12 is approximately 265mm long; each side 13, 14 is approximately 495mm long.

In the course of the manufacture of the tile, which will be described later in this specification, two score lines 20, 21 are provided in parallel spaced apart relationship relative to the sides 11, 12, in the face 15. The score lines 20, 21 serve to delineate into what appears from a distance when in situ three tiles of conventional size. To further enhance this appearance, the score lines 20, 21 each extend over the sides 11, 12 to further give the appearance of division in the tile 10.

The tile 10 also has two apertures 30, 31 for enabling the tile 10 to be secured to the roof structure. The lower face 16 has nibs 17 for enabling correct placement of the tile 10.

The tile 10 together with similar tiles can be mounted in a conventional manner on roof structure (not shown). Of course unlike conventionally sized tiles, which would require six nails for securement and a relatively long period of time to place in position, the tile 10 is secured with just two nails and is placed in position and secured considerably faster. Thus, there is considerable cost saving in installation. Where at the end of a row of tiles 10 there is insufficient space for a tile having the dimensions of the tile 10, a smaller sized tile may be installed.

In the manufacture, the tile 10, care must be taken to ensure that the score lines 20, 21 remain visible following curing of the tile 10. To this end and further to ensure that the extension of the score lines over the sides 13, 14 are visible following curing of the tile 10, the following mix of material has been found to provide the correct consistency of uncured tile 10 upon which the score lines 20, 21 may be made. 9600?j To 1000kg of sand is added 300kg of cement, 30kg of an appropriate dye (for tile colour) and 401 of water, which provides the appropriate consistency for scoring.

The invention is not limited by or to the specific embodiment described which can undergo considerable variation without departing from the scope of the invention.

Claims

CLAIMS :

1. A roof tile having dimensions equivalent to at least twice that of a conventionally sized tile and preferably three times that of a conventionally sized tile, the roof tile having one or more score lines which delineate the roof tile so as to provide the appearance of two or more conventionally sized tiles.

2. A roof tile as claimed in Claim 1 where the score line or lines extend(s) over the edge of opposing sides of the tile so as to give a more authentic appearance of a plurality of tiles.

3. A roof tile as claimed in Claim 1 or Claim 2 which comprises a cementitious material having dimensions approximately 265mm by 495mm with a thickness of approximately 8mm and which comprises two score lines thereby providing the appearance of three conventionally-sized tiles.

4. A roof tile as claimed in any of Claims 1-3 which, in the uncured state, is derived from a mix which comprises 1,000kg of sand, 300kg of cement, 30kg of an appropriate dye and 401 of water.

5. A roof tile substantially as hereinbefore described with reference to and as illustrated in the accompanying drawings .
