Description

Title of the invention: Mechanical tenon for roof tile Technical field of the invention

[0001] The technical field of the invention relates to a tenon for laying roof tiles on sheathing (or battens) supporting a covering (or roof). State of the art

[0002] Canal tile roofs comprise alternating courses and cover tiles, each courses being largely covered by the surrounding cover tiles. The canal tiles are laid on underlayment elements such as sheathing (or battens) and are held in place solely by friction between the tiles.

[0003] In a roof, most leaks are caused by a tile slipping and shifting, usually a short distance but enough to allow water to enter. If a cover tile slips, this is visible by looking at the roof; a repair can be carried out quickly and easily. If a center tile slips, this is much less visible; it is often necessary to climb onto the roof and inspect a whole area of ​​the roof to locate the slipped tile.

[0004] Among other reasons, the use of channel tiles has been abandoned in favor of tiles with molded lugs at at least one end. The lugs rest against a sloping back face of a batten, which prevents the tile from slipping. However, particularly at the roof edge, the tiles often need to be cut and the portion of the tile incorporating the lug removed. Tiles cut without a lug must then be mortared or fixed to the batten with hooks or nails, requiring tools.

[0005] Document DI = 1154094 describes a solution, and more specifically describes a retaining clip for roof tiles. The retaining clip of DI comprises a substantially U-shaped body including a base and two arms extending from the base. The arms include pointed projecting portions extending from the inner faces of the two arms. In order to connect the clip and the tile it retains to the roof substructure, the body of the clip must be attached to a fastener. A wire or a strip, for example, can serve as a fastener. The fasteners can be wrapped around the clip or attached securely to it, for example by spot welding (Section 14 of DI). After the clip is placed on a tile, the fasteners must be secured to the roof substructure, which clearly requires a tool and complicates the roofer's work. Summary of the invention

[0006] The invention proposes a technical solution to overcome all or part of the disadvantages described above.

[0007] To this end, the invention proposes a tenon for roof tile, tenon of the type comprising a body 10 substantially in the shape of a U comprising a base and two branches extending from the base, the branches comprising pointed projecting parts coming out of the inner faces of the two branches.

[0008] The tenon according to the invention is characterized in that it also comprises a support element extending from the base of the tenon body in a plane substantially parallel to the base.

[0009] After the tenon body is placed on the upper end of the tile, the tile is positioned on a substructure element of the roof, such as a batten (or sheathing), so that the supporting element rests on the upper face of said batten. Thus, once placed on a tile, the tenon according to the invention has the same function as a tenon molded into a tile. Installing the tenon according to the invention is quick and easy; it is done in a single movement consisting of inserting the upper end of a tile between the two arms of the tenon, without tools. Similarly, placing the tile on the substructure of the roof is easy and requires no tools. Installing the tenon according to the invention therefore requires less handling than using a retaining clip known elsewhere, such as the one described in DI, for example. The roofer's work is thus made easier.

[0010] In a roof, the tenon being positioned at the upper end of a tile, a flat tile, or a channel tile, the tenon is covered by another tile, flat tile, or channel tile. It is thus protected from the elements and does not undergo premature aging. Furthermore, being concealed by another tile, it is invisible from the outside and does not alter the appearance of the roof.

[0011] For all these reasons, the tenon according to the invention can thus be advantageously used for the renovation of historic buildings, the revaluation and reuse of existing tiles.

[0012] According to one embodiment, the body and the bearing element of the tenon are made together from a strip of bent thin sheet metal. Thus, the production of the tenon is simple and makes it possible to obtain, on an industrial scale, very inexpensive tenons.

[0013] The invention thus allows for the renovation of roofs at a lower cost. Presentation of the figures

[0014] The invention will be better understood, and other features and advantages of the invention will become apparent from the following description of an example of an implementation of the invention. This example is given by way of non-limiting example. The description is to be read in conjunction with the accompanying drawings in which: • Figure [1] is a view of a tenon according to the invention, • [Fig. 2] is a view of the tenon of [Fig. 1], from another angle

[0015] In the different figures, the identical elements, in their function or their structure, are referenced with the same reference points. Detailed description

[0016] As previously stated, the invention relates to a tenon for roof tile, of the type comprising a body 10 substantially in the shape of a U comprising a base 11 and two arms 12a, 12b extending from the base, the arms comprising pointed projecting parts 13 coming out of the inner faces of the two arms.

[0017] The tenon according to the invention is characterized in that it also includes a support element 20 extending from the base of the tenon body in a plane substantially parallel to the base 11.

[0018] The tenon according to the invention adapts to any type of tile. During its implementation, the body of the tenon is capped at one upper end of the tile and then the tile fitted with the tenon is placed resting on a sub-roofing element such as a batten (or sheathing).

[0019] The body and the bearing element of the tenon are made together from a folded strip of thin sheet metal. Ideally, the chosen sheet metal strip has sufficient mechanical strength and elasticity to allow it to be forcefully fitted over the top of the tile, to resist being pulled off once the tenon is in position on top of the tile, and to withstand weathering. In a concrete embodiment, the sheet metal strip is made of a metal such as galvanized steel or stainless steel. It has a thickness of approximately 0.5 to 1.25 mm and a width of approximately 10 to 25 mm. As can be seen in the figures, each fold is made across the width of the strip, and three folds are sufficient to make the tenon in its simplest version.

[0020] A distance between the free ends 14 of the branches can be chosen to be less than the width of the base 11. This ensures better anchoring of the protruding parts and thus limits the risk of detachment. This also allows for adaptation to different tile thicknesses. For example, the distance between the free ends of the branches can be chosen to be around 9 mm, for a tenon base width of around 14 mm.

[0021] In one embodiment, the free end 14 of one or both branches is bent in the opposite direction to the other branch to facilitate the insertion of the tenon at the upper end of the tile. In the example of [Fig. 1], the end fold extends across the width of the branch and has a length of approximately 1 to 2 mm.

[0022] In the embodiments shown in the figures, the protruding parts 13 are arranged on the lateral edges of the branches and there are two of them on each lateral side of each branch, i.e., four protruding elements in total. The parts in projections extend in an oblique direction relative to the branches and include a point directed towards the base.

[0023] In the examples shown in the figures, the protruding parts are made here by cutting the lateral edge in a direction forming an obtuse angle with said lateral edge and then folding; the result obtained [Fig.1], [Fig.2] is a protruding part of triangular shape, one pointed end of which is configured to grip the tile.
