Benefits of technology

The clip system provides enhanced security against high winds, reduces the risk of tile damage, and simplifies installation by allowing full nail insertion and adjustable hook positioning, ensuring tiles remain securely fastened across a range of conditions.

Problems solved by technology

Such tiles are typically terracotta or concrete and are relatively heavy.

first embodiment

[0043]A major advantage of the clip 205 of the first embodiment is that the distance between the hook 207 and the base 206 is adjustable, thereby enabling the clip 205 to be used with a wide range of tile sizes, shapes and configurations. Prior to installation, the hook 207 is spaced from the base 206 by a maximum extent. As seen in FIG. 7, the nail 4 is driven home into the batten 3, and then the hook 207 is pushed downwardly in the direction of the arrow in FIGS. 6 and 7 so as to engage the hook 207 with the tile 1.

[0044]A clip substantially in accordance with that illustrated in FIGS. 4-7 was used to fabricate a test roof five ridge tiles in length and four rows of tiles in width with a pitch of 18°, rafters at 600 mm intervals and terra cotta roof tiles. The test roof was tested in accordance with Australian and New Zealand standard AS / NZS 2050-2002 (Tests for Roof Tiles) by CSIRO MANUFACTURING & INFRASTRUCTURE TECHNOLOGY, North Ryde, Sydney, Australia. The clips were found to h...

third embodiment

[0048]Turning now to FIGS. 8-16, a deck clip 305 of a third embodiment suitable for rooves having a deck 51 is illustrated. As before the clip 305 is formed from an upper portion 301 and a lower portion 302. The upper portion 301 includes a hook 307, teeth 319 and stiffening ribs 320. The lower potion 302 includes a base 306 which extends at right angles from the adjustable strap 318 which interconnects the hook 307 and base 306. The strap 318 includes a ratchet housing 329 having a through aperture 322.

[0049]As best seen in FIGS. 9 and 12, the ratchet housing 329 preferably includes a release tab 330. This enables a screw driver or like implement to be inserted from below into the aperture 322 and thereby release the ratchet pawl (not illustrated). This may be necessary during roof repairs, for example.

[0050]The strap 318 is preferably a slightly loose fit within the aperture 322 and so can be worked slightly to the left or right as seen in FIG. 16. This better enables the desired ...

Abstract

A roof clip (205, 305) for roof tiles (1, 2) is disclosed in which a fastener (4) having a shank (24) which passes into a timber batten (3), or timber deck (51) is used to anchor the clip. The fastener is preferably preassembled with the clip to form an assembly able to be handled by the tile installer. The shank 24 passes through a base (206) the length of which pre-sets the distance between the batten and hook (107, 207). The distance between the hook and base is adjustable by means of a ratchet mechanism (229, 329). Consequently one clip can be used with a wide range of tiles. Tilers walking on rooves are less likely to break tiles held with such clips because the ratchet mechanism gives under the weight of the tiler so the clip does not form a rigid point about which the tile breaks.

Description

FIELD OF THE INVENTION[0001]The present invention relates to roofing tile clips, and in particular, to roofing tile clips for tile roofs constructed in cyclone prone areas.BACKGROUND ART[0002]In one form a conventional tiled roof, the roof is supported by rafters which run down the slope of the roof from a ridge line to an eave. Running substantially horizontally across the rafters are a plurality of lightweight timber bearers called battens which are spaced apart at a distance which approximately corresponds to the length of each tile. The battens can be fabricated from either softwood or hardwood. The tiles are placed on the battens with a higher part of each tile underlying a lower part of an adjacent tile. Such tiles are typically terracotta or concrete and are relatively heavy. Thus in those areas where high winds are not to be anticipated, the tiles are either maintained in position by their own weight, or tied to the batten by small gauge soft wire. However, in those areas su...
