-1 DEVICE FOR CONNECTING THE END OF SIDING BLADES

FIELD OF APPLICATION OF THE INVENTION

The present invention relates to the field of exterior cladding of cladding type facades and in particular to adaptations making it possible to ensure, under the best conditions, the connection between the ends of the blades making up this cladding.

DESCRIPTION OF THE PRIOR ART

Cladding can be defined in general by a facade cladding fixed to a frame itself fixed to the wall. This coating is composed of manufactured parts and more particularly by blades, that is to say substantially flat and elongated parts. These blades are not only fixed on the frame but also cooperate with each other to avoid any inter-blade space. To do this, these blades are conventionally preformed on their longitudinal edges to allow interpenetration of the longitudinal edges of the adjacent juxtaposed blades. During this fixing to the frame, certain blades are arranged in the extension of one another end-to-end, the faces of their ends being found opposite. This connection between the ends of the blades positioned in the extension of one of the other is called abutment.

In order to fulfill its protective function for the facade, it is particularly important that water or air cannot get too easily between the slats. It is therefore sought to achieve a minimum play in the butting.

There exists in the prior art the possibility of a preformation of the ends in order to propose a cooperation of the ends such as that existing between the longitudinal edges. However, such preforming requires removal of material which consists of creating complementary forms of retention and which must be carried out on site.

Such removal of material, when possible, weakens the blades and is likely to damage them. In addition, once the blade ends are fixed, the expansion phenomena to which the exterior cladding blades are subjected are likely to

- 2create stresses on the ends tending to break, once weakened.

Finally, a simple covering of one blade on the other or a simple baffle created by the complementarity of the forms provides only a limited air and water tightness.

DESCRIPTION OF THE INVENTION

What finding, the Applicant has conducted research aimed at optimizing the connection between the ends of the blades constituting an outer coating.

This research led to the design and production of a device for connecting the blades placed end-to-end with an external covering which is fixed on a frame itself fixed on a facade making it possible to obviate the drawbacks of prior art.

According to the invention, this device is remarkable in that it comprises at least one connection assembly formed by a lamella on the same side of which two points project, each point produced in the end of a blade a hole that it does not require ends of the blades to cooperate with different.

This feature is particularly advantageous in that the creation of a complex profile for the purpose of finger jointing. In fact, according to the invention, the drilling of holes in each end is sufficient, which makes the operations to be carried out on the blades easier. These operations can thus be carried out on the installation site.

By requiring only the production of holes, the invention avoids weakening of the ends to abut and avoids the rupture of the latter in the event of expansion.

The invention thus proposes a simple and practical solution making it possible, by means of an additional connecting device, to butt-joint the blades of an external cladding type cladding without the drawbacks of the solutions of the prior art.

According to another particularly advantageous characteristic, the device comprises two connecting assemblies formed by a strip and two projections. More specifically, the device comprises two connection assemblies formed by a strip equipped with two projections:

-3 a first connection assembly cooperating with holes drilled in the blades perpendicular to the facade to which the blades are fixed,

- A second connection assembly cooperating with holes drilled in the blades parallel to the surface to which the blades are fixed.

The implementation of two connection assemblies optimizes the fixing.

According to another particularly advantageous characteristic of the invention, the blades, the connection assemblies and the skirts are made of the same synthetic material. According to another particularly advantageous characteristic of the invention, the blades, the connection assemblies and the skirts are made of polyamide PA6.

The Applicant has endeavored to ensure that this connection device is not only easily installable but also little or not visible from the outside.

To do this, according to another particularly advantageous characteristic of the invention where the blades are preformed on their longitudinal edges so as to have at least one rebate allowing the edge of a blade to slide in the edge of the adjacent blade, the device is remarkable in that the preformation of the longitudinal edges of the blades consists of the production of a U-shaped groove whose central bar is pierced, parallel to the surface to which the blades are fixed, at the end of the blade of one of said through holes of said points of the connecting assembly.

Similarly, still in a situation where the blades are preformed on their longitudinal edges so as to present at least one rebate allowing the sliding of the edge of a blade in the edge of the adjacent blade, the device is remarkable in that the preformation longitudinal edges of the blades consists of producing a tongue cooperating with said U-shaped groove, said tongue being pierced, perpendicular to the facade to which the blades are fixed, at the end of the blade of a said through holes of said points of the connecting assembly.

-4 As the connection assemblies are positioned in the rebate or in the tongue covered by the rebate, they remain invisible from the outside.

According to another particularly advantageous characteristic of the invention, the ends of the points projecting from the lamellae open onto the rear face of the blades and cooperate with a skirt coming to marry the rear face of the two abutting ends of the blades, said skirt being preformed with orifices allowing it to come to position on said points. This skirt creates an obstacle behind each inter-blade end space guaranteeing the protection of the facade.

According to another particularly advantageous characteristic of the invention, the ends of said points are preformed with flats parallel to the facade when the connection assemblies are engaged in the holes drilled in the blades parallel to the surface to which the blades are fixed. These flats will facilitate the positioning of the skirts.

According to another particularly advantageous characteristic of the invention, the body of said points comprises a cylindrical portion preformed on their face coming opposite radial grooves. The presence of these grooves and their orientation will tend to bring the ends of the blades closer together in order to at least decrease if not eliminate the inter-blade space.

According to another particularly advantageous characteristic of the invention, the lamella cooperates with an extension in order to create a spacer interposed between the tongues and the bottom of the grooves of the blades by positioning in the U-shaped groove in order to provide a different spacing between the longitudinal edges of the blades.

The fundamental concepts of the invention having just been exposed above in their most elementary form, other details and characteristics will emerge more clearly on reading the description which follows and with reference to the appended drawings, giving by way of 'nonlimiting example, an embodiment of a device according to the invention.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

As illustrated in the drawing in FIG. 1, the connection device, referenced D as a whole, comprises a plurality of connection assemblies 100 formed by a strip 110 on one face of which two points 120 and 130 are projected. These assemblies of connection will serve as staples to the blades placed end-to-end of an external covering such as those illustrated by the drawing of the

- 6figure 5, staples which will cooperate with holes drilled in the end of each blade coming opposite.

As illustrated in the drawing of FIG. 2, the connection assembly 100 can be associated with an extension 200 whose usefulness will be described below. Said riser is formed by a parallelepiped wedge comprising, on one of its faces, a groove 210 for retaining the strip 110 of the connection assembly 100.

As illustrated in the drawings of FIGS. 3a and 3b, the device further comprises a skirt 300 which is interposed between the rear face of the blades 400 and the facade (not shown) by matching said rear face and by cooperating with the connection assemblies 100. This skirt 300, crossed by orifices 310 and 320, comprises on the rear face of positioning fins 330 and 340 and, on its upper edge, needles 350 and 360 whose usefulness will be described below.

As illustrated in the drawing of FIG. 4, the blade 400 is of the type of that preformed:

on a longitudinal edge 410 so as to present at least one rebate forming a groove adopting a U-shaped profile, and

- on its other longitudinal edge 420 so as to present a tongue coming into said U-shaped groove.

These preformations allow the adjacent blades to be assembled by their longitudinal edges as illustrated in the drawing in FIG. 6.

According to the invention, the blade 400 is also preformed at its two ends with two holes:

a first hole 430, 430 'drilled in the central bar of the U-shaped profile formed by the sheet of the rim 410. This hole 430, 430' is drilled along a transverse axis parallel to the surface to which the blades are fixed,

- A second hole 44 0, 44 0 'drilled in a rear rib 42 0 of the preformed tongue in the flange 420. This hole 440, 440' is drilled perpendicular to the facade to which the blades are fixed.

As illustrated in the drawings in FIGS. 5 and 6, once the blades have been butted together, the spacing between the holes from one blade end to the other corresponds to the spacing of the points 120 and 130 of the connection assembly 100 .

Thus, as illustrated in the drawing in FIG. 7, the connection assemblies 100 are put into place in said holes. For each connection between two ends of different blades, the device D comprises two connection assemblies 100 with:

a first connection assembly 100 cooperating with the holes 440, 440 'drilled in the tongues of the blades perpendicular to the facade to which the blades are fixed,

- A second connecting assembly 100 cooperating with the holes 430, 430 'drilled in the blades parallel to the surface to which the blades are fixed.

According to the illustrated embodiment, an additional spacing is sought in the longitudinal connection between the blades 400, this is the reason why an extension 200 is associated with certain connection assemblies 100 (cf. also FIG. 2) positioned in the U-shaped groove to provide different spacing between the longitudinal edges of the blades.

As illustrated, the connection assemblies 100 are positioned in the sheet or on the tongue itself covered with the rebate so that the connection assemblies are invisible from the outside of the facade.

As illustrated in the drawing in FIG. 8, the ends of the points 120 and 130 projecting from the slats 110 of each connection assembly 100 open onto the rear face of the blades 400 and cooperate with a skirt 300 coming to marry the rear face of the two ends abutting blades 400, said skirt being preformed with holes 310 and 320 which allow it to be positioned on said points.

As illustrated in the drawing in FIG. 1, the ends of said points 120 and 130 are preformed with flats 121 and 131 parallel to the front or to the rear face of the blades 400 (when the connection assembly is positioned in the holes 430, 430 'of axis parallel to the front or the rear face of the blade 400). These flats 121 and 131 find their utility in the sliding of the skirt 300 between said flats 121 and 131 and the rear face of the blades. Indeed, the flattened surface, as illustrated in the drawings of Figures 9, 10 and 11, facilitates positioning and holding in position. Although not illustrated in these drawings, the fins 330 and 340 of the rear faces of the skirts 300 (cf. FIG. 3) are

- 8 put in contact with the ends of said points to finalize the attachments of both the skirts 300 and the connecting assemblies 100 by tending to bring the points 120 and 130 together.

As illustrated in the drawing in FIG. 1, the bodies of said points 120 and 130 comprise on their base a cylindrical portion preformed on their face coming opposite to radial grooves 122 and 132. It is understood that these grooves 122 and 132 will create an additional constraint tending to bring together the ends linked by the connection assemblies 100.

As illustrated in the drawings of FIGS. 3, 12 and 13, the needles 350 and 360 preformed on the upper edge of the skirts form at least one marking template in the groove of the edge 410 of the blade 400 for drilling purposes on site. holes 430 and 430 '.

It is understood that the device, which has just been described and shown above, has been for disclosure rather than for limitation. Of course, various arrangements, modifications and improvements could be made to the example above, without however departing from the scope of the invention.
