Description

DEVICE FOR THE INSTALLATION OF CLINS.

The present invention relates to the field of facade cladding coatings. It relates more particularly to means for posing such clapboard. The clapboard is a plank that can be used to build a facade of a building; they are then arranged horizontally overlapping one another to prevent the penetration of water under the effect of a flow or wind. Each clap is fixed by screwing or nailing to vertical cleats.

The clapboard, formerly made of wood, is today also offered in concrete, fiber cement or composite. They require a team of at least two people to be laid because they are long and sometimes heavy; in addition, this pose must be sufficiently precise to meet in particular adequate collection standards, ensuring that water will not penetrate the back of the clapboard coating.

The invention aims to provide a device for laying clapboard facade with sufficient precision and preferably with a reduced workforce. To achieve its purpose, the invention proposes a support for the laying of a second blink on a first blink, comprising:

- a first part which includes support for the support on an upper edge of the first clap;

- a second part which includes a seat for resting a lower edge of the second wink;

a frangible zone ensuring a junction of the two parts with each other, the first part comprising:

an anvil disposed at the front of the first part so that a force back and forth on the anvil, the second part being immobilized, causes a separation of the parts; and,

a tongue extending downwards in front of the frangible zone;

and further comprising:

- Retaining means forming with the tongue an elastic clamp which a vacuum opening is less than a thickness of the first clap.

Preferably, the retaining means have a shape of "U" of which a first bar extends downwardly from a rear end of the support (11) and a second bar extends upwards, to the before the first bar.

The second portion may include an amount, the support extending rearwardly from an upper end of this amount and the seat extending forwardly from a lower end of the amount.

The second bar advantageously forms an angle, preferably acute, open downwards, with the upright, a maximum opening of this angle, measured empty relative to the upright, preferably being greater than the thickness of the first clap. The anvil is preferably arranged cantilevered at the front of the upright, so that the force back and forth, applied to a front plate of the anvil, the second part being immobilized, causes the separation of the two parts.

The tongue can extend downward in the extension of the front plate of the anvil.

The second part may comprise a stop disposed at the front of the seat.

The frangible zone preferably comprises a narrowed section of the upright at its junction with the first part.

The second part may comprise a handle, for the withdrawal of this second part when it is separated from the first. The amount and the abutment can form, under the seat, between them and in their mutual extension, a loop forming with the seat a ring-shaped handle.

Advantageously, the support and the seat define between them a distance corresponding to an overlap between the clapboard.

Preferably, the support is formed in one piece.

Figures 9 and 10 illustrate an operation of the variant of Figure 8.

Fig. 11 illustrates a third embodiment for the support of Fig. 1; and,

Figures 12 and 13 illustrate an operation of the variant of Figure 11.

Figure 1 illustrates in isolation a support device 1 for the installation of a second clinch 2 in recovery of a first clinch 3; FIG. 6, in particular, illustrates the support 1 in the position of use. The support 1 comprises:

a first part 4 serving as support for the device 1 on an upper edge 6 of the first clinch 3; and,

- A second part 7 on which a lower edge 8 of the second clinch 2 is expected to arise.

The two parts 4, 7 are divisible between them, that is to say that they can be easily separated from one another, as particularly illustrated in FIG. 7. The first part 4 of the support 1 comprises a support 11, an anvil 12 and retaining means 13. The second portion 7 of the support 1 comprises a substantially vertical upright 14 extending from the support 11 downwards, seating means 16 and a stop 17. In FIG. furthermore, in the illustrated example, this second part comprises a handle 18. The support 11 is a plate which extends substantially horizontally rearwards from an upper end 21 of the upright 14. The restraint 13 extends in the extension of the support, downwards, forming an angle close to a right angle with the support 11. A lower end 23 of the retainer 13 flares downwardly relative to the upright 14, so as to facilitate the penetration of the upper edge 7 of the first clinch 3 between the upright 14 and the restraint 13, under the support 11.

The anvil 12 comprises a front plate 26, vertical. The anvil is retained at the bottom by the front end of a cantilever extending at the front of the upright 14, in the horizontal extension of the support 11. The anvil 12 is retained at the top by a crutch resting substantially in the middle of an upper face of the support 11. The anvil constitutes the foremost part of the first part 4 of the support 1. The length of the support 11 is close to twice that of cantilever 27, lengths measured from front to back.

In the illustrated example, the second part 7 of the support 1 has a hook shape; that is to say that the upright 14 and the abutment 17 are in the extension of one another and together form a loop 28 in the lower part of the second part 7. The upright 14 rises substantially vertically from the rear of the loop 28 to the underside of the first portion 4 at the junction of the support 11 and the cantilever 27. The stop 17 goes up substantially vertically from the front of the loop 28 , about halfway up the amount 14.

In the example shown, the seat 16 has the shape of a substantially horizontal cylindrical bar; it extends between the upright 14 and a lower part of the abutment 17, so that the stop extends upwards, beyond the seat 16. The handle 18 is formed by the loop 28 below the seat 16, constituting a ring for the passage of a finger. As illustrated in FIGS. 2 and 3, the support 1 defines, between the underside of the support 11 and the top of the seat 16, a distance D substantially equal to the desired recovery distance R for the second wink on the second.

As particularly illustrated in Figure 4, the section of the upper end 21 of the upright 14 decreases at the approach of the first portion 4; the junction of the second part 7 with the first part 4 is therefore a fragile zone 30, frangible, and therefore a preferred breaking zone facilitating the separation of the two parts, as will be described with reference to Figures 6 and 7.

FIG. 5 illustrates a different embodiment of the junction between the two parts 4, 7. In this embodiment, the upright 14 has a substantially constant thickness; horizontal holes 31 are formed immediately below the first part 4, forming a "dotted" precut locally reducing the section of the upright and creating, as in the embodiment of Figure 4, a fragile zone 30, frangible, and therefore a preferred breaking zone facilitating the separation of the two parts 4, 7.

We will now describe a method of laying for the second clinch 2 after the first clinch 3, with reference to Figures 6 and 7.

As illustrated in Figure 6, the support 1 is placed so that the support 11 rests on the upper edge 6 of the first clap. The second seam is then placed so that its lower edge 8 rests on the seat 16 and the second seam 2 rests against the front plate 26. Preferably, at least two supports are used, so that the second seam 2 n It no longer needs to be held, a single operator can then fix, for example by nailing or screwing, the second wink on the structure of the facade. When laying the fasteners, a force is exerted backwards in the direction Fl (see Figure 6). This force is generally sufficient to break the support 1 by separating the first part 4 from the second part 7. If the effort provided by the installation of the fasteners is not enough, a mallet blow can help separate the two parts. The first part is then ejected towards the rear according to the arrow F2 and the second part 7 can be removed from between the clips 2,3, with the handle 18, from the bottom, in the direction F3 (see Figure 7).

FIG. 8 illustrates a second embodiment of the support of FIG. 1, which will be described in that it differs therefrom.

In the example illustrated in FIG. 8, the support 1 comprises a tongue 32 extending downwards, substantially in the extension of the front plate 26 of the anvil 12, at the end of the cantilever 27. This tongue has a thickness E32 which is small relative to a current thickness E14 of the upright 14.

As in the operating mode illustrated in FIGS. 6 and 7, the first part 4 and the second part 7 of the support 1 are separated from each other by a force exerted on the anvil 12, towards the rear, according to the direction Fl.

However, unlike in the case illustrated in FIG. 7, the first part 4 is not ejected; indeed, the tongue 32 abuts against the front face of the first clinch 3. As particularly illustrated in Figure 10, once the second second part 7 removed, the tongue 32 remains pinched between the first clinch 3 and the second clinch 2 ; the first part 4 is thus maintained in support straddling the upper edge 6 of the first clap. We will now describe a third embodiment for a support 1 on the invention, in that it differs from the second embodiment, with reference to Figures 11 to 13. Figure 11 illustrates the support 1 in isolation. This support, like that described above with reference to FIGS. 8 to 10, comprises a tongue 32. The third embodiment differs mainly from the previous embodiment in the shape and function of the retaining means 13. As illustrated in FIG. 13 has substantially the shape of a "U". A first bar of the "U" extends downwardly from a rear end 39 of the support 11. The base 42 of the "U" forms a circular arc whose concavity is oriented upwards and which extends the first bar from its low end. The second bar 43 extends the base upwards and forwards. The second bar thus forms an acute angle A43, open downwards, with the upright 14. In the lower part of the second bar 43, a maximum opening of the angle A43, measured empty relative to the upright 14, is greater than one. thickness EC, substantially constant, clinks 2, 3. In the isolated position of Figure 11, a free end 44 of the second bar 43 is in the vicinity of the junction between the first portion 4 and the second portion 7. In this position a maximum distance E44 measured perpendicularly between the free end 44 and the tongue 32 is smaller than the thickness EC of the clapboards 2, 3.

The retainer 13 is elastically deformable from front to back, that is to say that a force exerted back and forth on the free end 44 causes its rearward movement and the folding of the second bar 43 to the first bar 41. At the same time, the whole of the retainer 13 tends to swing backwards around the rear end 39 of the support 11. The tongue 32 and the retaining means 13 thus form an elastically deformable clip. The distance E44 between the free end 44 and the tongue 32 constitutes a vacuum opening of this clamp, that is to say the opening of the clamp when it is not stressed by any external force to the support 1.

When it comes to place the support 1 on the first clinch 3, the thickness EC of the clinch 3 being less than the opening E43, the clinch easily enters between the upright 14 and the second bar 43. In addition, because the angle A43 formed initially between this bar 43 and the upright 14, the clinch 3 spreads them gradually, until taking the position of Figure 12, wherein the support 11 rests on the upper edge 6 of the clinch 3. The upright 14 and the second bar 43 then form a clamp which holds the support 1 hooked elastically at the first inclination 3.

As illustrated in FIG. 13, when the second part 7 of the support 1 is separated from the first part 4, then withdrawn, the retainer 13 expands and the second bar 43 tilts towards the front of the support 1 away from the first bar 41. Nevertheless, the gap E44 between the tongue 32 and the second bar being initially less than the EC thickness of the clin, the tongue 32 and the second bar 43 then form a clamp which holds the support 1 hooked elastically to the first 3. The embodiment of FIGS. 8 to 10 and that of FIGS. 11 to 13 are particularly advantageous. Indeed, to allow a circulation of air and water at the back of the clapboard while avoiding that animals, including rodents, penetrate, a rodent grill is arranged horizontally, down, at the back clapboard The presence of the tongue 32 prevents the first parts 4 accumulate on the grid, at the risk of clogging it, preventing the circulation of air and water.

The third embodiment makes it possible to guarantee better attachment of the support 1 to the first clinch 3.

In the illustrated examples, the clinch support 1 is molded in one piece from a plastic material. Preferably, the carrier is of a biodegradable material, so that the first portion, which is ejected backward, degrades naturally if it remains trapped in a vacuum at the rear of the cladding coating.

Of course, the invention is not limited to the preferred embodiments which have just been described but, on the contrary, the invention is defined by the following claims.

It will be apparent to those skilled in the art that various modifications can be made to the embodiments described above, in the light of the teaching that has just been disclosed.

Thus, a support according to the invention may not include anvil; the separation of the two parts being obtainable, for example, by a lateral rotation of the second part relative to the first part along a suitable frangible zone.

Through the use of supports according to the invention, a single person can lay clapboard clapboard. This significantly increases the speed of installation, for the same team. In addition, the laying precision is increased and the necessary overlap between the clapboard is guaranteed. Instead of being made in one piece, a support according to the invention can be made in two parts sliding between them, each part corresponding to a respective part, so that the displacement of the first part towards the rear releases the second, by sliding.
