Abstract

A roofing tile retention clip has a head 10 of hook-like configuration adapted to engage a grooved or recessed edge (20 Fig. 5) of a roofing tile and a flexible tail 11 of strip form extending from the head and being adapted for securement to a roof structural element with the tail laid flat or flexed downwardly by a nail extending in a direction either parallel to or normal to the recessed edge of the tile. The tail is provided with at least one hole 16 but usually two axially-spaced holes, to receive the nail or nails, and at its head-remote end with a sleeve 14 disposed normally to the tail longitudinal axis and adapted to locate a nail to be secured in the roof structural element parallel with the recessed edge of the tile. <IMAGE>

Description

SPECIFICATION A tile retention clip The present invention relates to a roofing tile retention clip.

Roofing tiles are held in place by means of retention clips, which must provide a firm link between the tiles and the framework of the roof. The design of a tile clip is influenced by three main parameters, namely the position of the clip on the tile, the position of the tile on the roof and the type of roof tile. This variety of requirements has previously been met by having a selection of retention clips wide enough to match the permutations provided by the abovementioned parameters. This is a problem for the rooflayer who, for each job, must have at his disposal enough different kinds of retention clip to cope with all the positions of tiles on the roof and clips on the tiles.

The object of the present invention is to obviate or mitigate the abovementioned problem.

According to the present invention there is provided a roofing tile retention clip comprising a head of hook-like configuration adapted to engage a grooved or recessed edge of a roofing tile and a flexible tail of strip form extending from the head and being adapted for securement to a roof structural element by a securing device extending in a direction either parallel to or normal to the recessed edge of the tile.

Preferably, when the retention clip is secured normally to the roof structural element, the tail is either laid flat on or flexed downwardly onto the roof structural element and is secured by nailing. The tail preferably is provided with at least one hole, but usually two axially-spaced holes, to receive the nail or nails.

Preferabiy, the retention clip has at its headremote end a sleeve disposed normally to the tail longitudinal axis and adapted to locate a nail to be secured in the roof structural element parallel with the recessed edge of the tile, the tail, in this instance, usually being flexed downwardly relative to the head.

An embodiment of the present invention is described below with reference to the accompanying drawings, in which: Figure 1 is a perspective view of a tile retention clip according to the present invention; Figure 2 is a perspective view of a roofing tile; Figure 3 is a perspective view of a tiled roof; and Figures 4 and 5 are perspective views of tiles held in place on different parts of the roof of Fig. 3 by the tile retention clip of Fig.

1.

Referring to Fig. 1, the tile retention clip is formed of a plastics material, such, for example, as nylon (super tough nylon). The clip comprises a hook-like head 10 integral with a tail 11 of strip form. The tail 11 has a major portion 12 extending away from the head 10 and a minor portion 13 extending parallel to and forwardly of the hook-like head 10. The major tail portion 12 terminates in an integral sleeve 14, whereof the bore 15 is transverse or normal to the longitudinal axis of the tail 11. The tail 11 between the head 10 and the sleeve 14 is formed with two axiallyspaced holes 16 separated by a strengthening rib 17 about which the tail 11 can flex. The forward end of the tail 11 terminates in a strengthening or bearing rib 18.

Referring to Fig. 2, a roofing tile 19 is formed along two opposed parallel sides with a recessed or grooved configuration 20 each consisting of two parallel recesses or grooves 21. The configurations 20 are oppositely facing, i.e. when the tile 19 is laid in position on a roof one configuration will be facing upwardly and the other downwardly. Also, each configuration 20 provides a step at its respective tile edge.

The tile 19 has, in terms of its disposition in use, a left ridge corner A, a right ridge corner B, a left eave corner C, and a right eave corner D.

Fig. 3 shows a perspective view of a roof 22, showing the arrangement of tiles with respect to the ridge 23, eaves 24, gables 25 and verges 26.

There are nine basic positions for the tiles 19; tiles 19A in the centre ridge positions have three edges adjacent other tiles and one edge adjacent the ridge, centre tiles 19B have all four edges adjacent other tiles, centre eave tiles 19C have three edges adjacent other tiles and one edge adjacent an eave, left and right hand verge ridge tiles 19D and 19E respectively have two edges adjacent other tiles and one edge adjacent each of the ridge and the verge, left and right hand verge tiles 1 9F and 19G respectively have three edges adjacent other tiles and one edge adjacent a verge, and left and right hand verge eave tiles 1 9H and 1 9J respectively have two edges adjacent other tiles and one edge adjacent each of the verge and the eaves.

Fig. 4 illustrates a tile clip TC in use, fixing centre tile 19B above underlying centre tiles 19B1 and 19B2. Underlying tiles 19B1 and 19B2 are located on a batten 27 which extends across rafter 28.

The head 10 of the clip TC engages with the grooved ribbed edge 20 of the centre tile 19B. The head 10 engages in the groove 21 remote from the main body of the tile 1 9B and the short extension 13 engages under te tile 19B so that the tile 19B is firmly gripped at its top and lower surfaces. The main tail length 12 and a nail 29 is driven through the sleeve 14 in the batten 27. The nail 29, as can be seen, is parallel with the grooved edge 20 of the tile 19B. Since the centre tile 19B overlaps the join between underlying tiles 19B1 and 19B2, the clip TC also retains these tiles at the left hand ridge corner A of 19B1 and at the right hand ridge corner B of 19B2.

Variation in the amount the tail strip 11 is flexed allows for all common types of tile to be fastened down in this way using the clip TC.

Centre ridge tiles 19A are secured at the left eave corner C as described above for centre tiles 19B, and their right and left ridge corners A and B are secured by ridge tiles overlapping them.

Fig. 5 shows a clip TC in use for securing centre eave tiles 19C. Centre eave tile 19C is located on a batten 30 and a fascia board 31, and is secured at right and left ridge corners A and B by the overlap of neighbouring tiles towards the ridge. Left eave corner A is fixed by locating the clip head 10 into the grooved edge 20 of the tile 19C as shown and driving a nail 32 through one of the holes 16 into the fascia board 31. It is to be noted that the tail 11 of the clip TC lies flat on the fascia board 31 and that the nail 32 is driven into the latter in a direction normal to the grooved edge 20 of the tile 19C.

However, where the clip TC is used at the facia board 31 with deep profile tiles it sometimes needs to be flexed downwards for securement (by nailing purposes).

Claims
