Description:
TITLE TILE RETAINING MEANS The present invention relates to a tile retaining means.

A typical pitched, tiled roof comprises rows of tiles overlapping rows of lower positioned tiles along a lower edge, in a manner that is repeated down the roof.

The present invention relates to securing tiles, more preferably flat shingles or tiles, to a structure such as a roof or wall. The invention will in part be described in relation to flat type tiles but it should be appreciated that the invention is not so limited. The term tile used herein shall be taken to mean a roof tile or a slate or timber or other material shingle or any similar roofing material.

BRIEF DESCRIPTION OF THE KNOWN ART It is known to use a clip that is secured to a roof batten in a suitable manner, to hold the lower end of an upper tile down, and in doing so, keep the upper end of the next tile down the roof secured to the roof structure as well. Known clips generally achieve this by retaining the leading edge of the upper tile with a hook, the shank of which then winds its way between the overlapping portion of the tiles back to an anchor point at, or near the roof structure. In effect, the upper tile is only held down at its leading edge by this hook, which in turn is exposed to the detrimental affects of the elements. As such, the ability of such an arrangement to stand up to winds of extremely high force has been questioned.

Furthermore, from a security point of view, an individual wishing to gain access to a building via the roof, merely has to bend open the hook to remove a tile.

It is an object of the present invention to provide a tile retaining means that overcomes or at least substantially ameliorates the problems associated with the tile retaining clips of the prior art.

Other objects and advantages of the present invention will become apparent from the following description, taken in connection with the accompanying drawings,

wherein, by way of illustration and example, an embodiment of the present invention is disclosed.

BRIEF STATEMENT OF THE INVENTION In one form of this invention although this may not necessarily be the only or indeed the broadest form of this there is proposed a tile retaining clip adapted to be secured to the under surface of a tile, the clip having a free end adapted to engage and be retained by a supporting roof baton.

Preferably the tile retaining clip has a portion with a surface area to be adhered to the undersurface of a tile.

Preferably the tile retaining clip is adhered to the undersurface of the tile adjacent lower end (when installed on a roof), the free end extending downwardly to engage the baton.

Preferably, the tile-retaining clip, having an upstanding web, an upper elongate strip portion extending to one side of the web, and a lower projecting portion extending to the other side of the web, having a downwardly curved lip.

Preferably, the roof batten supports roofing tiles, the batten being generally Z- shaped in cross section, wherein the batten has an upstanding web, an upper flange extending to one side of said web, and a lower flange extending to the other side of said web, the flanges being substantially parallel, and wherein the free end of the tile retaining clip engages under the upper flange of the baton.

Preferably, the upper elongated strip portion includes a plurality of holes passing through which adhesive passes to assist in adhering the tile retaining clip to the undersurface of the tile.

Preferably, the tile-retaining clip is secured to the roof batten by means of the downwardly curved lip at the free end, which is adapted to engage the upper flange of the roof batten.

Preferably there is a weather strip adapted to support roof tiles and to extend between adjacent roof battens and to be supported thereby, each weather strip having a length such that in use its lower end portion projects beyond the lower

one of the adjacent battens, whereby each tile is supported along its opposite margins by adjacent weather strips with the upper surface of each said strip being in contact with and supporting adjacent marginal edge portions of adjacent tiles positioned in edge-to-edge relationship, wherein the weather strip includes at least two longitudinal strips of sealant means in use adapted to seal under the respective side edges of adjacent tiles.

BRIEF DESCDRIPTION OF THE DRAWINGS For a better understanding of this invention it will now be described with respect to the preferred embodiment which shall be described herein with the assistance of drawings wherein; Figure 1 is an isometric view of the tile retaining clip according to the preferred embodiment of the present invention; Figure 2 is a side view of the tile-retaining clip in Figure 1, Figure 3 is a top view of the tile-retaining clip in Figure 1, and Figure 4 is a cross sectional view through the battens showing the tile-retaining clip in normal use, retaining tiles to roof structure.

DESCRIPTION OF THE PREFERRED EMBODIMENT Now referring to the illustrations, and in particular to Figure 1, a tile retention clip 1 comprises an upstanding web 2, upper elongate strip portion 3 extending to one side of the web, and a lower projecting portion extending to the other side of the web 4, having a downwardly curved lip 5.

The roof support batten is a Z-shaped batten 7, comprising an upstanding web 20 with an upper flange 22 extending from the upper end of the web 20 and a lower flange 24 extending from the lower end of the web 20. The upper flanges and lower flanges extend in opposite directions but are substantially parallel. The lower flange has longitudinal corrugations and terminates in an upwardly turned lip 28.

Referring now to Figure 4, where in use, it can be seen the roof structure according

to this invention comprises battens 7 and 8 mounted to rafters 12 with tiles 13,14 and 15 supported on weather strips 25,27 and 30 by the battens. Underneath adjacent tiles in each row of tiles there are tile retention clips 16 and 17, which fasten to battens 7 and 8 respectively, retaining tiles 13 and 14 proximate their lower edges. In this position under the tiles, the retention clips are well protected from the detrimental affects of the weather.

Clips 16 and 17 attach to the roof battens 7 and 8 respectively via the downwardly curved lips 5, which engage the respective upper flanges 22 of the roof battens. The nature of the shape of the lip 5, and the rolled steel from which it is preferably formed, are such that they give the lower portion a springy quality that minimises rattling of the assembly in use.

Each tile overlaps the next tile lower down the roof structure, as illustrated, where tile 13 overlaps tile 14, and tile 14 overlaps tile 15.

The tile retention clip 1 is secured to the tile 13, via a suitable adhesive 41, applied to the upper elongate strip portion 3. There are a plurality of holes 40 in the upper elongate strip portion, through which the adhesive 41 can pass, thereby strengthening the bond between the tile and the clip. This adhesive bonding is repeated for clip 17 and tile 14, and for all subsequent tiles down the roof.

The retention clips are attached to the tiles so to avoid interference with the weather strips. Two equally spaced clips per batten, per tile is preferable, but more can be used if there is a perceived need.

Although the invention describes the retention clips being adhered to the undersurface of the tiles, it is to be realized the clips can be attached by, for example, rivets, screws or bolts. However using an adhesive is the preferred form of the invention for other forms of attachment may protrude through the upper surface of the tile.

Thus it can be seen the tiles can be quickly and easily laid by pushing the tile down the slope of the roof until the end of the retention clip engages under the upper flange of the batten, it is simple action to click the retention clip under the flange.

The downwardly curved lip assists in engaging the flange of the batten to deflect the end of the clip downwardly to be retained by its resilience under the flange of the batten.

The retention clip according to this invention may be constructed from any convenient material. The material may be sheet steel such as galvanised steel or pre-painted steel or it may be stainless steel, aluminium or copper. Alternatively the retention clip may be constructed partially or wholly from wire.

It is considered therefore that tile retention means such as those described herein would prove to be of considerable benefit to those who wish to maximize both the integrity and security of their tiled roof or wall.

Although the invention has been herein shown and described in what is conceived to be the most practical and preferred embodiment, it is recognised that departures can be made within the scope of the invention, which is not to be limited to the details described herein but is to be accorded the full scope of the appended claims so as to embrace any and all equivalent devices and apparatus.
