Description

LITEAU

  The invention relates to a new batten for

  roofs, in particular roofs covered with tiles.

  The battens are usually formed by wooden slats fixed transversely at regular intervals, on the rafters of the frames to serve as

  point of attachment to the roof tiles.

  For a long time we tried to ensure the fixing of the tiles by hanging them on the battens using metal clips caught between the nose of the upper tile

  and the underside of the batten on which the tile rests

  adjacent, the clips at least partially surrounding the battens An example of such an assembly is described for example in Australian patent N 0552 771 or in the

  French patent application no. 90 03516.

  The commercial development of these clips is limited by the fact that, due to the diversity of the sizes of the battens, it is necessary to provide a great diversity -Q of clips suitable for each size of battens In addition, it is currently impossible to have only one clip model on the same roof due to the presence of rafters

  which very often require the use of clips

  rafters. If, at first glance, it seems simple to solve this problem by studying a shape of clip able to adapt to the largest size of batten and to serve at the same time as a chevron pass, this solution is not in fact economically acceptable because, the clips being made of stainless steel with very high elastic resistance, such a clip

  universal would be prohibitively expensive.

  On the other hand, even the best-studied current clips need to be installed with great care in order to ensure that they are properly hooked, in particular under the batten, which implies the use of particularly attentive staff and a time of relatively important pose. The invention aims to remedy these drawbacks and to provide a device which authorizes the use of a single type of clip, eliminates the chevron-pass clips, this clip being moreover of reduced size compared to known clips, therefore much more economical, and very large

simple installation.

  C_ The invention is embodied by a batten formed by a profile comprising in section at least one base and a substantially horizontal upper range connected together by a substantially vertical flank pierced with holes regularly distributed along its longitudinal axis, the base and the upper shelf being arranged on either side of the sidewall whose holes serve as a point of attachment at the end of a clip in

spring steel wire.

  Such a strip has a very high inertia and can therefore be used on a very wide variety of roofs with very different spacing between rafters. The presence of holes regularly distributed along the side of the profile eliminates the need to surround the batten from below to ensure the attachment of the clip which allows the use of clip whose size is very small and eliminates the obligation to use herringbone passes The economy of an expensive material which results is such that it allows the additional cost of the profiled batten to be absorbed compared with conventional battens, the device according to the invention taken as a whole being considerably less expensive than conventional devices The angle formed between the base and the side of the profiled constitutes a guide for the ends of the clips as long as they have not been engaged in the holes, which provides two advantages: on the one hand, it allows placement at the blind since it is enough for the roofer after having hooked the upper end of the clip to the upper tile to exert pressure on the free branch of the clip to automatically find a hanging hole in which the free end of the clip will engage of itself; on the other hand this allows during the laying of the first row of tiles to quickly catch any layout errors as long as the ends of the clips

  have not been engaged in the battens' holes.

  According to a first preferred embodiment of the invention, the batten is a Z-shaped section in section. According to a second preferred embodiment, the

  batten is a trapezoidal profile in section.

  Advantageously in this second embodiment, the two sides of the batten are pierced with holes, the two rows of holes being offset from one another by half a pitch, so that there is only one hole in a section so as not to decrease the moment

of inertia of the whole.

  According to another advantageous characteristic, the base (or the bases of the profile in the case of the trapezoidal profile) is pierced with small holes for the passage of the points or screws for fixing the batten on the rafters and the passage of assembly rivets of two battens between them. On the other hand, the invention makes it possible to advantageously solve the problem of the bottom slope strips. We know that the bottom slope strip must be raised, since the underside of the first row of tiles rests directly on the strip, while on the rest

  from the roof, this lower face rests on another tile.

  The profiles according to the invention are easily superimposable and can therefore be fitted together by means of a wedge of corresponding shape, the two faces of which have

  clips in the holes in the sides of the profiles.

  Other features and benefits of

  the invention will emerge from the description below

  of nonlimiting exemplary embodiments with reference to the appended drawings in which: FIG. 1 represents a view in longitudinal section of an assembly of tiles with a known batten and clip device, FIG. 2 is a perspective view of a first embodiment of a batten according to the invention with a Z section, FIG. 3 is a perspective view of a second embodiment of a batten according to the invention with a trapezoidal cross section, FIG. 4 is a side view of an assembly of tiles with the batten of FIG. 3,

  Figure 5 is a section along line IV-IV of-

  Figure 4, Figure 6 is a perspective view of an assembly wedge to form a bottom slope strip with two profiles of Figure 3, Figure 7 is a sectional view of a bottom strip slope made with the wedge in Figure 6 and

profiles of Figure 3.

  Figure 8 is a sectional view of a bottom slope batten made with the wedge of Figure 6 and

profiles of Figure 2.

  In Figure 1 we see two adjacent tiles 1 and 2 assembled on a batten 3, formed of a wooden slat, by a clip 4 This clip has an upper beak 5 turned -0 by 90 D relative to the general plane of the clip and that

  Hangs on the outside edge of the top tile 1.

  The clip continues downwards through a vertical part 6, an oblique part 7, a horizontal part passing under the batten 3, a vertical part 8 rising from the other

  side of the batten and ending with a loop 9.

  In Figure 2 we see a first example of

  preferential embodiment of a batten according to the invention.

  In this example, the batten 10 is constituted by a Z-shaped section comprising an upper horizontal surface 11, an oblique flank 12 and a horizontal base 13 opposite the upper surface 11 relative to the flank 12 This flank is pierced with a longitudinal row of 14 holes regularly

  spaced near the angle between sidewall 12 and base 13.

  These holes 14 are of a diameter such that they allow easy engagement of the stop-forming end of a clip which will be described in more detail below.

  description The base 13 is also pierced with holes 15 of

  smaller diameter for the passage of nails, screws or other rivets for assembling the battens to the rafters of the roof or

battens between them.

  In Figure 3 is shown in perspective a second embodiment of the invention in the form of a profile of trapezoidal section 16 In this drawing we have used the same references as in Figure 2 to designate the concordant parts namely the range upper 11, the sides 12 pierced with holes 14, and the

bases 13 with holes 15.

  In Figure 4 we see in section an assembly of two tiles 1,2 on the batten 16 of Figure 3 by means of a clip 17 very simplified compared to clip 4 of Figure 1 This clip 17 includes, like the clip 4, an upper spout 18 for hooking on the edge of the upper tile 1 as seen in more detail in the figure The spout 18 is extended downwards by a vertical portion 19 which extends substantially to the lower level of a hole 14 of the profile 16, then passes via a turn 20 to a horizontal part 21 2 C situated substantially at the level of the upper part of the hole 14 The clip 17 is terminated by a stop 22 which in this exemplary embodiment is formed by a loop and which

  serves as a retainer against the internal face of the sidewall 12.

  We see in Figures 6 and 7 the constitution of a bottom slope 23 by means of two battens 16 according to Figure 3 superimposed and held together by a wedge 24 of concordant shape provided on its oblique sides with clips 25 cooperating with the holes 14 of the oblique faces 12 of the two profiles 16 The wedge 24 is preferably made of an injectable plastic material, such as for example a polyamide Holes 26, corresponding to the holes 15 of the bases 13 of the profiles 16, are provided in the legs of the wedge 24 It is possible to simplify the assembly by eliminating the pins 25, the fixing of the two sections 16 and of the wedges 24 being then only ensured

  for mounting by the fixing screws on the rafters.

  The wedge 24 also makes it possible to very easily form battens or parts of battens with reinforced inertia as it becomes necessary when

  the spacing between the rafters is important.

  With this wedge, it is also possible to form battens at the bottom of the slope with profiles 10 with a Z-section a as illustrated in FIG. 8 It is also possible without departing from the scope of the invention to use only one

  half-shim cut along the axis 27 of Figure 8.

  It is understood that the invention makes it possible, with a single batten profile and a single clip model, capable of being mass produced, capable of being adapted to practically all types of usual frames while being inexpensive, simple and quick to install and

  superior resistance to currently known devices.

  The invention provides other advantages in particular: it ensures effective ventilation of the undersides of the tiles, thanks to the holes in the profiles, it makes it possible to use, in attractive economic conditions, materials ensuring improved durability of the works: thus, due of the lightness of the battens, it is possible to use lacquered steel or stainless steel which, unlike wood, are insensitive to attack by insects and very resistant to humidity. It is also possible in the context of the invention to use moldable or extrudable materials such as aluminum or plastics, the battens according to the invention are stackable so that their storage and transport volume is very reduced. The invention is not limited to the exemplary embodiments which have been described. Thus, in the case of the Z-shaped profile, the flank 12 could be vertical instead of being oblique. It could also be provided on a Z-shaped profile with flank 12 vertical or oblique of the raised edges at the ends of the area 11 and of the base 13 Similarly, in the case of the trapezoidal profile, the two sides 12 could be vertical In the preferred embodiment described in FIG. 3, the two sides 12 have a row of holes 14, but the invention also relates to the profiles of which only one flank is drilled. A shim 24 has been described suitable for the profiles with trapezoidal section, but it goes without saying that any shim having a shape corresponding to that profiles to which

  it adapts will fall within the scope of the invention.

  Likewise, two examples of bottom slopes have been described, consisting of two superimposed strips 10 or 16 with interposition of a wedge or a half-wedge 24 This assembly is the one which will give the best results, in particular in terms of inertia However, it is of course possible, without departing from the scope of the invention, to constitute a bottom slope batten with a single batten 10 or 16 and a wedge or half-wedge 24 fixed together.
