FR2824855A1 - HOOK FOR FIXING LID-MOUNTED TILES ON ROOF LITTLES - Google Patents

Abstract

The fastening clip (1), made from metal and pref stainless steel wire, has at least one spiral loop (5) and two branches (4) with hook-shaped ends (4A) to grip the tile (2) and batten (3). The tips of the hooks are curved inwards towards the centre of the clip and in the same plane as the branches, with which they form an angle of pref 45 deg.

Description

a main face (150a, 150b) of the supporting structure (100).

  The present invention relates to a hook for the fixing of mechanical tiles mounted on overlapping battens.

of roof.

  Mechanical tiles are now widely used for roofing. These tiles, the shapes of which can be very diverse, in particular as a function of the curve of the tile, are always laid in the same manner, that is to say overlap, and have this effect, at their longitudinal and transverse edges, numerous beads capable of delimiting canals and participating in the maintenance of an overlapping assembly by overlap. This covering can be done from the right to the left of the roof or vice versa. To allow a mounting assembly to be held, it is

  ncessary to use tiling units.

  However, due to the possibility of mounting by right or left covering the tiles on the] 5 battens, the first fixing hooks developed about twenty years ago were profiled to keep the upper transverse edge of a tile assembled, intended to be covered by the lower transverse edge of a next tile in the direction of the roof, a support strip for the area of overlap of the tiles. The fixing only in the upper part of the tile makes it possible to disregard the direction of the overlap mounting. However, wind tunnel tests and on-site performances have shown that, if the tiles are not

  fixed in the upper part, their nose is likely to lift.

  the tile clicks and the water can easily spread. With each click, the tile can lose its initial position, or even break. Consequently, these hooks

  fixation have not given our entire satisfaction.

  Recently, therefore, fasteners located at the bottom of the tile have appeared on the market. LG device known this day consists of an extended hook of a tab which is fixed, by a nailing operation, a strip. However, this hook is not universal. I1 need two models, one for fixing on overlapping tiles to the right, the other for fixing on overlapping tiles to the left. The need for two types of fixing hooks increases the

  stocEs at roofers. Otherwise.

  the poE operation of such a hook is tedious because it requires. each fitting step, a nailing operation. It results in excessive fetalization of the installer and

  a risk in the nailing operation.

  An object of the present invention is to propose a new fixing hook whose design allows this hook] o to be universal and to be positioned either on the right or left longitudinal edges of the tiles and this

in a very short time.

  Another object of the present invention is to provide a fixing hook capable of being located at the bottom of the tile and whose design allows, for a surface of one square meter, to fix all the tiles without multiplying

  very important the number of hooks to use.

  Another object of the present invention is to provide a fixing hook whose design of the fixing makes it possible to place the hook without additional member and in

It's an extremely short time.

  To this end, the subject of the invention is a hook for fixing macanic tiles mounted overlapping on roof battens, characterized in that the hook is specially shaped to hold the lower transverse edge of a tile covering the edge assembled. upper transverse of a next tile in the direction of the roof to a support strip of the overlap area of said tiles, this hook consisting of two divergent branches connected at one of their ends by at least one loop of pace spiral forming a spring to tend towards the approaching of the branches when they are under tension, the free ends of the branches being on the one hand curved in the direction of the inter-branch space, on the other hand oriented to extend on one side or on the other side of the plane passing through the divergent branches and thus form a universal hook which can be positioned indifferently by simple inversion on the long banks right or left tiles in the vicinity of the overlap area of the

  lower and upper transverse edges of the tiles.

  The invention will be clearly understood on reading the

  following description of exemplary embodiments, in

  reference to the accompanying drawings in which: FIG. 1 represents a diagrammatic view in perspective of a first embodiment of a hook according to the invention: 3s FIG. 2 represents a diagrammatic view in perspective of another embodiment a hook according to the invention; FIG. 3 represents a schematic view of a hook in the state fixed respectively to the lower tranevereale bank of a tile and to a batten, the detail of this fixing having been shown in an enlarged manner: FIG. 4 represents a similar view in FIG. 3 from a slightly different angle of view, the detail of the fastening having been shown in an enlarged manner, FIG. 5 represents a schematic view similar to FIG. 3. the angle of view having been modified again, the detail of the fixing having been shown in an enlarged manner and the figure represents a schematic view of a fixing hook in the state fixed on the one hand to the lower transverse edge of a tile, on the other hand to a strip, the tiles maintained in this way being of the type with mounting by overlapping on the left, the detail of the

  fixing having been shown in an enlarged manner.

  2s The hook 1, object of the invention, is more particularly intended for fixing mechanical tiles 2 mounted overlapping on battens 3 of the roof. As mentioned above, mechanical tiles 2 can have a large number of shapes. A distinction is thus made between flat appearance tiles, weakly curved tiles and strongly curved tiles. The tiles are conformoss to allow overlapping mounting at the longitudinal edges and overlapping interlocking at the transverse edges. The details of the realization of these tiles will not be provided in this request for

  patent because it is well known to those versed in this art.

  The hook 1, object of the invention, is in turn specially profiled to maintain assembled the bottom tranveral bank of a tile 2, covering the top tranveral bank of a next tile 2 in the sen of the roof, a batten 3 support for the one 2C tile cover 2. Such a mounting is more

  particularly shown in Figures 3 6.

  This hook 1 is made up of two divergent branches 4 linked one of their ends by at least one spiral-shaped bubble forming a spring in order to tend towards bringing branches 4 together when they are under tension. The free ends 4A of the branches 4 have on the one hand bent in the direction of the inter-branch space, on the other hand oriented so as to extend from one side or the other of the plane passing through the divergent branches 4, it is understood that these ends 4A extend from one same cat to the plane regardless of the side chosen. In other words, the free ends 4A of the branches can extend respectively above, or below. of the plane passing through the divergent branches 4 when the hook is positioned with its divergent branches 4 extending in a horizontal plane or extending respectively right or left of the plane passing through the divergent branches 1orquG the divergent branches 4 are positioned in a vertical plane. This hook thus forms a universal hook which can be positioned either by simple turning, as illustrated in FIGS. 3 and 6, on the right longitudinal edges 2A or left 2B of the tiles 2 in the vicinity of the area 2C of overlapping of the lower transverse edges and superior of the tiles 2. The hook 1 can, depending on the number of turns of the loop 5 of spiral shape forming a spring connecting the branches 4 divergent shape between them, affect a large number of shapes. So. in the example reprAsentd in FIG. 1, the loop 5 comprises a turn. ^ Conversely, in Figure 2, the loop 5 of spiral shape has two turns which can be superposed or spaced from each other. Thus, this hook may include at least one turn depending on the spacing between the battens and the edge

  lower crossover of the overlapping tile.

  One of the free ends 4A of the branches 4 of the hook l is therefore positioned on a right longitudinal bank 2A or left 2B of the tile 2 while the other free end 4A of the branch 4 of the hook l is positioned under the batten 3, as illustrated in figure 4, by

just plugging into it.

  The ends 4A of the divergent branches 4 are. in the fixed state of the hook l to the tiles 2 and to the batten 3, oriented so that the loop 5 is positioned, relative to the direction of the slope, upstream of the points of attachment of the hook to the batten 3 and to the bank longitudinal 2A, 2B of tile 2, so as to avoid the formation of a path

  of water flow between roof and batten 3.

  This hook 1 can be formed by deformation of a continuous wire, preferably metallic, preferably stainless steel. The result is a manufacturing process

  extremely simple and economical hook.

  As mentioned above, the same hook makes it possible, by virtue of its positioning, to keep applied against one another, on the one hand the lower transverse edge of a tile, on the other hand the upper transverse edge of the next tile in the direction of the roof. Note, as illustrated in Figures 3 and 6, that the hook l fits over overlapping tiles on the right (Figures 3 to 5) and on overlapping tiles on the left (Figure 6) by simply inverting the hook l. In fact, in FIG. 3, the hook is positioned so that the free ends 4A of the divergent branches 4 of the hook 1 extend to the left relative to the plane formed by said branches 4. Conversely, in the Figure 6, these free ends extend to the right relative to the plane forms. This transition from one to the other is obtained by simple inversion of the hook. Thus the stock of hooks nocessaires to the realization of such roofs is constituted by a soul hook module. IT results in a

  simplification of the management of such a stock.
