FR2549879A1 - Self-fastening shingle or tile. - Google Patents

Abstract

The invention relates to a self-fastening shingle or tile 1, especially for cladding, the said shingle 1 comprising: a. On the back face 2 of its upper edge 3, a rib 4 parallel to the said edge 3 and whose bottom forms a dihedron 5 making an acute angle with the rear surface 6 of the said shingle 1; b. On the back face of their central portion, a listel 14 parallel to the rib 4, the bottom of which listel 14 forms a dihedron with the surface of the back face 6 of the shingle 1. It is characterised in that: the top 3 of the shingle, above the rib 4, has a tenon 15 of a few centimetres in height, and in that the listel 14 has the shape of a nose or hook curved over downwards which can cover the tenon 15 with a clearance of at least one centimetre.

Description

Technical area
The present invention relates to a shingle or special self-adhesive tile for badges, said shingle comprising a) on the reverse of its upper edge, a rib parallel to said edge and the underside of which forms a dihedral 9 at an acute angle with the rear surface of said bead, said dihedral being intended to hang on a horizontohtal batten the top of which forms a dihedral at an even more acute angle with the vertical wall or the rafters, b) on the latch of their median part, a listel parallel to the rib, listel whose below forms a dihedral with the surface of the back of the shingle, said dihedral being intended to be applied to the upper edge of the lower shingle.

 It also relates to cladding made with tiles or shingles of the family indicated above and which also have the characteristics of the invention which will be explained below.

Problbze ask
I1 is responsible for quickly and economically making cladding whose shingles are firmly attached to the wall.

State of the Prior Art and Disadvantages
We know shingles which are tiles for making roofs but, more generally, vertical cladding. They are sometimes called armpits, essences or even tavaillons. Their conventional fixing is carried out by nailing on the wall or on battens.

 However, nailing requires an abundant and expensive labor and each shingle is held only by its upper end so that in case of significant mechanical effort (wind, snow or other) the upper edge of the shingles is subjected to a significant bending stress which sometimes causes falling and deterioration of the cladding.

 To remedy this, it has been proposed, in particular, in the German patent HALBE n0854 254, of December 8, 1949, to provide on the reverse of each tile or shingle, a nose curved downward which can hang on a batten chamfered correspondent and, moreover, to provide on the reverse of said shingle, near its lower edge, a curved strip downwards which is placed on the upper edge of the lower shingle. The underside of this strip conforms to the upper shape of the lower shingle. The disadvantage of this device is that it is necessary to provide very high precision in the installation of the battens. However, this precision is not compatible with usual building practices. In addition, sometimes a frame plays with time and weather, so that the shingles may also go away.

 It is to avoid the aforementioned drawback that provision has been made for improving the invention.

Statement of the invention
The invention is mainly characterized by the fact that the top of the shingle, above the rib, has a tenon a few centimeters high and that the strip has the shape of a nose or hook bent downward which can cover the tenon with a clearance of at least one centimeter.

 According to a stone embodiment, the listel has, on the underside, a groove with two sides perpendicular to the bottom, the outer side having a height of more than one centimeter.

Solution to the problem, advantage and industrial results
With the vertical play, which the invention of the tenon allows in the lower groove of the listel, a cladding is obtained whose shingles remain firmly attached, even if the battens are not placed strictly parallel to each other nor are they strictly equidistant from each other. each other.

 The invention will be better understood using the description below which gives a nonlimiting example of practical embodiment which is illustrated in the accompanying drawings.

Figure 7 is a partial perspective view of a cladding made with shingles of the invention, seen from the inside if we assume the wall on which is hung the removed cladding.

Description of an embodiment
The shingle (1) or self-adhesive tile has, on the reverse (2) of. its upper edge (3), a rib (4) parallel to the edge (3). The underside of this rib (4) forms a dihedral (5), at an acute angle with the posterior surface (6) of the shingle (1).

 On the posterior surface (6) or reverse of the middle part of the shingle (1), there is provided a listel (14, 141, 142), psrallel to the rib (4). This strip (14, 141, 142) has the underside designed to fit on the upper edge (3) of the lower shingle (11, 12).

 The rib (4) is intended to hang on horizontal battens (7, 71, 72, 73) the top of which forms a dihedral (8) at an even more acute angle with the vertical wall (9) or the rafters (10 , 101).

 In general, the strip (14, 141, 142) has on the underside, a groove (17) whose sides (18, 19) are perpendicular to the bottom (20).

 An important characteristic of the invention resides in the fact that the external flank (19) has a relatively large height, that is to say that the groove (17) is deep so that it can compensate for the defects of parallelism battens (7, 71, 72, 72) provide a play (16), more or less important.

Claims (3)

 1. A shingle or self-adhesive tile (1) special for cladding, said shingle (1) comprising: a) on the reverse (2) of its upper edge (3), a rib (4) parallel to said edge (3) and of which the underside forms a dihedral (5) at an acute angle with the rear surface (6) of said shingle (1), said dihedron being intended to hang on a horizontal batten (7) whose top forms a dihedral (8) at an angle even more Higu with the vertical wall (9) or the rafters (10), b) on the reverse of their middle part, a listel (14) parallel to the rib (4), listel (14) whose underside forms a dihedral with the surface of the reverse (6) of the shingle (1), said dihedron being intended to be applied to the upper edge of the lower shingle (11), characterized by the fact that the top (3) of the shingle, at above the rib (4), has a tenon (15) a few centimeters high, and that the strip (14) has the shape of a nose or hook curved downward which can cap the tenon (15) with a mo game ins a centimeter.  2. Shingle as defined in claim 1, characterized in that the strip (14) has, on the underside, a groove (17) with two flanks (18, 19) perpendicular to the bottom, the outer flank (19) having an additional height. of a centimeter.  3. Cladding made with shingles as defined in either of claims 1 or 2, ceract ized by the fact that the battens (7, 71, 72, 73) are not necessarily strictly parallel nor strictly equidistant.
