Abstract

A device (1) for closing an opening in the wall of a building, comprising four lateral profile members (2-5) together forming a frame (6) for receiving and holding a closing plate (7) oriented in a plane (P1). The locking profile members (8-11) cooperate with longitudinal ribs (110) provided on the lateral profile members (2-5) in order to effectively retain the closing plate (7). Removing the locking profile members (8-11) requires little effort due to interruptions (21, 22, 31, 32, 41, 42, 51, 52) in the longitudinal ribs (110) that allow the locking profile members (8-11) to be removed by sliding them longitudinally relative to the lateral profile members (2-5).

Description

DEVICE FOR SHUTTING AN OPENING IN THE WALL

A BUILDING

TECHNICAL FIELD OF THE INVENTION

The present invention relates to the field of the building, and more particularly relates to a device for closing an opening in the wall of a building.

To seal an opening in the wall of a building, devices are known comprising four lateral profiles forming between them a frame for receiving and holding a shutter plate oriented in a plane. The plate can be made of various materials: wood, metal, plastic or glass for example. The frame is fixed to the masonry of the building.

To fix the closure plate between the side profiles, it is generally used glazing beads which are reported and fixed on the side profiles snap. The glazing beads are often attached and fixed on the inner face (that is to say oriented towards the interior of the building) of the frame to make them inaccessible to intruders located outside the building.

For security issues against intrusions, it is necessary to ensure a good retention of the shutter plate in the frame. This requires a snap of the glazing beads according to a significant effort, even important. Otherwise, a thrust on the shutter plate, exerted from outside the building to the interior of the building, could be enough to disengage the glazing beads and separate the shutter plate from the frame.

There is the problem that the greater the retention of the closure plate, the greater the mounting forces by the installer must be important to snap the glazing beads. Simultaneously, subsequent disassembly of the glazing beads (to change the shutter plate for example) becomes extremely difficult without damaging them.

The document WO 201 1/121039 A2 describes a device according to the preamble of claim 1 for closing an opening in the wall of a building.

SUMMARY OF THE INVENTION

A problem proposed by the present invention is to provide a closure device for an opening in the wall of a building, allowing a good retention of the closure plate without requiring significant effort on the part of the installer . Simultaneously, the present invention aims to provide a device for closing an opening in the wall of a building whose shutter plate can be changed without much effort on the part of the installer.

To achieve these objects as well as others, the invention provides a device according to claim 1 for closing an opening in the wall of a building.

For the purposes of the present invention, a longitudinal locking interlock is understood to mean a relief or a recess extending in a so-called longitudinal direction and capable of opposing a force exerted in a transverse direction (in this case according to the second axial direction which is perpendicular to said longitudinal direction). The direction of extension (or elongation) of a longitudinal latching lock coincides with the direction of elongation of the lateral profile or the locking section bearing said longitudinal locking bias.

Thanks to the longitudinal interruptions of the longitudinal ribs, the locking profiles can at least be removed from the lateral profiles by simple translational movements, without excessive effort. The first and second longitudinal locking notches can thus have shapes (transverse sections) providing a very large transverse retention capacity in order to effectively limit the risks of separation of the locking profiles of the lateral profiles by a transverse force induced by a thrust exerted on the blanking plate from the outside of the building towards the interior of the building.

Preferably, the first or second longitudinal locking biasing may comprise a plurality of longitudinal notches. This adjusts the distance between the free end of the first tab and the inner surface of the longitudinal flange to adapt to the thickness of the closure plate.

Advantageously, the first and second longitudinal locking notches may comprise a plurality of longitudinal notches. This increases the retention of the locking profile on the longitudinal rib against a transverse force (along the second axial direction).

Preferably, it can be provided that:

the first longitudinal locking bias is disposed on the first face of the longitudinal rib,

the second longitudinal locking catch is arranged on the inside face of the second tab, a third longitudinal locking bias is arranged on the second face of the longitudinal rib,

a fourth longitudinal latching recess is disposed on the inner face of the first lug, said fourth longitudinal latch cooperating by interpenetration with the third longitudinal locking crease when the longitudinal rib of one of the two opposite lateral sections of the frame is received between the first and second legs.

The third and fourth longitudinal locking notches allow to further increase the retention of the locking profile on the longitudinal rib against a transverse force (in the second axial direction).

Advantageously, it can be provided that:

- The locking profiles are adapted to receive the longitudinal rib between their legs by a simple translational movement relative to the second axial direction by means of an elastic spacing of the free ends of the first and second legs one away from the other,

- Each locking profile comprises at least the second longitudinal locking bias on the inner face of the second leg, while each of the longitudinal ribs comprises at least the first longitudinal locking bias on its first face.

The elastic spacing of the free ends of the first and second legs apart from one another allows mounting of the locking profiles on a longitudinal rib easier and faster. This elasticity does not, however, affect safety: even in the event of elastic deformation of the locking section (induced by a thrust on the closure plate from the outside of the building towards the interior of the building for example), the first and second longitudinal locking notches remain mutually engaged and cooperate to retain the closure plate.

Preferably, the distance between the longitudinal rib and the base in the first axial direction may allow a reception of the second tab between the longitudinal rib and the low play base in the first axial direction. In particular, it is possible to provide a clearance of between 1, 2 and 2 times the interpenetration height of the longitudinal locking notches along said first axial direction.

Advantageously, the closure device may comprise at least one U-shaped generally U-shaped cross section profile substantially identical to the generally U-shaped cross section of the profile sections. locking, with first and second legs defining between their inner faces a housing adapted to receive the longitudinal rib of one of the two opposite side profiles of the frame, wherein the inner faces of the first and second branches are devoid of any longitudinal notch of locking.

Being devoid of any longitudinal locking bias on the inner faces of the first and second branches, the trim profile can be engaged and removed on the longitudinal rib by a simple translation in the second axial direction, without much effort. The trim profile allows an extension of the (or) locking profile (s) to visually provide a single glazing impression formed by the (or) locking profile (s) and (or) profile (s) dress put together end to end.

Preferably, it can be provided that:

a third longitudinal locking bias is arranged on the second face of the longitudinal rib,

the device comprises at least one generally U-shaped cross-section covering section substantially identical to the generally U-shaped cross section of the locking profiles, with first and second branches defining between their internal faces a housing adapted to receiving the longitudinal rib of one of the two opposite lateral sections of the frame, in which only the inner face of the first leg is provided with a fifth longitudinal interlocking locking engagement cooperating with the third longitudinal locking interlock of said longitudinal rib; when the longitudinal rib of one of the two opposite side profiles of the frame is received in the housing between the first and second legs.

Such a trim profile again allows an extension of the (or) locking profile (s) to visually provide a unique glazing impression formed by the (or) profile (s) locking and (or) profiled (s) dress put together end to end. The fifth longitudinal locking bias allows the trim section not to inadvertently disengage from the longitudinal rib and / or allows the trim profile to participate somewhat in a retention of the closure plate.

The fact that the inner face of the second leg has no longitudinal locking bias allows removal of the trim profile without much effort. For example, it is possible to insert a tool between the closure plate and the free end of the first leg in order to leverage and tend to disengage the fifth longitudinal locking biasing out of the third longitudinal locking bias.

According to another particular aspect of the present invention, the frame may be adjustable in width and / or height. The dimensions of the frame can thus be adapted to the exact dimensions of the opening to be closed. This is very useful when it is necessary to close the building urgently after a broken window or window.

Advantageously, it can be provided that:

the ends of the lateral profiles of the frame penetrate slidingly in corner pieces,

adjustment means make it possible to adjust the length in which the ends of the lateral profiles penetrate into the corner pieces.

In the case of an emergency closure of the opening of the building following a broken window or window, it is thus possible to build approximately (thus rapidly) a frame to the dimensions of the opening by cutting the side profiles and locking (and possibly dressing). After assembly of the lateral profiles with the corner pieces to form the frame, the adjustment means make it possible to adapt the height and width of the frame according to the exact dimensions of the opening for a good shutter.

Preferably, it can be provided that:

the ends of the lateral profiles of the frame are provided with a protrusion in the general shape of V,

- The adjustment means comprise, on the corner pieces, jaws forming between them a substantially V-shaped housing whose width can be selectively modified by spacing or relative approximation of said jaws.

Such means are simple and allow a strong support of the frame against the masonry table according to very important efforts.

Advantageously, it can be provided that the adjustment means make it possible to adjust the length in which the ends of the lateral profiles penetrate into the corner pieces in a continuous manner. Continuous adjustment allows a fine adjustment of the dimensions of the frame to the dimensions of the opening in which the device is to be installed.

Preferably, it can be provided that:

the device comprises a first face intended to be oriented towards the outside of the building and a second face intended to be oriented towards the interior of the building, - The adjustment means are operable only by access to the second face of the device.

It is thus possible to give access to the adjustment means only from inside the building for good security.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

Figures 1 to 5 is illustrated a first particular embodiment of device 1 for closing an opening in the wall of a building.

FIGS. 3 to 5 show more particularly that this closure device 1 comprises four lateral sections 2 to 5 forming between them a frame 6 for receiving and holding a closure plate 7 oriented along a plane P1, said closure plate 7 having an edge 7a and two opposite faces 7b and 7c. The closure device 1 also comprises locking profiles 8 to 1 1.

At least two of the opposite lateral sections of the frame 6 (lateral sections 2 and 4 on the one hand, or lateral sections 3 and 5 on the other hand, and preferably all the lateral sections 2 to 5) each have a cross section such that illustrated in Figures 1 and 2. This cross section comprises:

o a base 9,

a longitudinal wing 10 extending in a first axial direction 11 substantially parallel to said plane P1, from the base 9 towards the inside of the frame 6 to a free end 10a, said longitudinal wing 10 having an inner surface 10b intended to to receive by pressing one of the two faces 7b or 7c of said shutter plate 7 (here the face 7b),

o a longitudinal rib 1 10 extending from and away from said longitudinal flange 10 in a second axial direction ll-ll (which is here substantially perpendicular to said plane P1) and located away from the base 9 according to the first axial direction 11, said longitudinal rib 1 10 having a first face 1 10a directed towards the base 9, said longitudinal rib 1 10 having a second face 1 10b opposite the first face 1 10a and intended to receive in abutment the edge 7a of said shutter plate 7.

In Figure 3, we see that the device 1 comprises at least two locking profiles (8 and 10 on the one hand or 9 and 1 1 on the other hand, and preferably all four). As illustrated in Figures 1 and 2, these locking profiles 8 to 1 1 have a generally U-shaped cross section having a first leg 12 and a second leg 13 terminating in free ends 12a and 13a. The first and second legs 12 and 13 define between their faces 12b and 13b a housing 14 adapted to receive the longitudinal rib 1 10 of the lateral sections 2 to 5 of the frame 6.

The free end 12a of the first tab 12 is intended to abut against the other of the two faces 7b or 7c of said closure plate 7 (here the face 7c).

At least one of the first 1 10a or the second 1 10b face of the longitudinal rib 1 10 (here the first face 1 10a) has a first longitudinal locking latch C1.

At least one of the first 12 or the second leg 13 has on its inner face 12a or 13a (here the second leg 13 on its inner face 13a) a second longitudinal locking latch C2 cooperating by interpenetration with the first longitudinal notch locking C1 of said longitudinal rib 1 10 when the longitudinal rib 1 10 of one of the lateral sections 2 to 5 of the frame 6 is received in the housing 14 between the first 12 and second 13 tabs. The longitudinal locking notches C1 and C2 cooperate to oppose a force F applied to the first face 7b of the closure plate 7.

It is seen more particularly in Figure 3 that said locking profiles 8 to 1 1 elongate at first distances D8 to D1 1 respectively.

The respective longitudinal ribs 1 of said lateral sections 2 to 5 of the frame 6 each comprise at least one longitudinal interruption 21, 22, 31, 32, 41, 42, 51 and 52 along a second distance D21, D22, D31, D32, D41. , D42, D51 and D52 allowing the removal of the locking profiles 8 to 1 1 by a longitudinal sliding movement of said locking profile 8 to 1 1 in the interruption 21, 22, 31, 32, 41, 42, 51 or 52.

In practice, to allow such withdrawals by longitudinal sliding, it has been provided here respectively that:

D21 and D22 are greater than or equal to D8;

D31 and D32 are greater than or equal to D9;

- D41 and D42 are greater than or equal to D10;

D51 and D52 are greater than or equal to D1 1.

To adapt to the thickness E of the shutter plate 7 the engagement of the locking profile 8 to 1 1 on the rib 1 10, the first longitudinal locking latch C1 comprises a plurality of longitudinal notches.

For its part, the second longitudinal locking bias C2 comprises a single longitudinal notch. The second longitudinal notch of locking C2 could however also comprise a plurality of longitudinal notches, as in the variant illustrated in FIG. 6.

In this FIG. 6, which is a cross-sectional view of a lateral profile 2 to 5 and of a locking profile 8 to 1 1 for the construction of a second embodiment of closure device 1, it can be seen that than :

the first longitudinal locking latch C1 is disposed on the first face 1 10a of the longitudinal rib 1 10,

the second longitudinal locking bias C2 is disposed on the inner face 13a of the second tab 13,

a third longitudinal locking bias C3 is disposed on the second face 1 10b of the longitudinal rib 1 10,

a fourth longitudinal latching recess C4 is disposed on the inner face 12a of the first lug 12, said fourth longitudinal locking latch C4 cooperating by interpenetration with the third longitudinal latching crease C3 when the longitudinal rib 1 10 of one of the lateral sections 2 to 5 of the frame 6 is received between the first 12 and second 13 tabs.

The presence of the third C3 and fourth C4 locking longitudinal notches makes it possible to improve the retention of the locking profiles 8 to 1 1 on the longitudinal ribs 1 10 against transverse forces.

In both embodiments, the locking profiles 8 to 11 may, in a first mode of manipulation, be engaged on the ribs 1 10 of the lateral sections 2 to 5 by a reverse movement to that leading to their withdrawal, c ' that is to say:

- by respectively arranging the locking profiles 8 to 1 1 in one of the interruptions 21 or 22, 31 or 32, 41 or 42, 51 or 52, by placing the housing 14 in the extension of the longitudinal ribs 1 10,

- Then by sliding the locking profiles 8 to 1 1 according to the elongation directions of the lateral sections 2 to 5, so as to penetrate the longitudinal ribs 1 10 in the housing 14, to bring the locking profiles 8 to 1 1 in their positions illustrated in Figure 3.

The locking profiles 8 to 1 1 may also have a certain capacity for elastic deformation allowing an elastic separation of the free ends 12a and 13a of the first 12 and second 13 tabs one away from the other.

In such a case, the locking profiles 8 to 1 1 can then be engaged on the ribs 1 10 of the lateral sections 2 to 5 in a second mode manipulation device consisting of a simple translational movement T relative to the second axial direction ll-ll (Figure 2). During such a translational movement T,

There occurs an elastic spacing of the free ends 12a and 13a of the first

12 and second 13 tabs one away from the other which allows the reception of the longitudinal rib 1 10 in the housing 14 provided between the tabs 12 and 13.

It is then advisable to provide that each locking profile 8 to 1 1 comprises (as illustrated in FIGS. 1 and 2) at least the second longitudinal locking bias C2 on the inner face 13a of the second tab 13, while each of the longitudinal ribs 1 10 comprises at least the first longitudinal locking biasing C1 on its first face 1 10a. Indeed, in the case of a force F on the closure plate 7, exerted from the outside of the building towards the interior of the building, it has been found that the locking profile 8 to 1 1 tends to deform by elastic spacing of the free ends 12a and 13a of the first 12 and second 13 tabs one away from the other. During this deformation, the inner face 12b of the first leg 12 tends to move away from the second face 1 10b of the longitudinal rib 1 10 while the inner face 13b of the second leg 13 is pressed against the first face 1 10a of the longitudinal rib 1 10. Providing at least C1 and C2 notches as illustrated in Figures 1 and 2 thus allows a good cooperation of the locking profiles 8 to 1 1 with the side sections 2 to 5 to effectively retain shutter plate 7.

FIGS. 2 and 6 show more particularly that the gap EC between the longitudinal rib 1 10 and the base 9 in the first axial direction 11 allows reception of the second tab 13 between the longitudinal rib 1 10 and the base 9 to weak clearance J in the first axial direction ll. The clearance J may advantageously be between 1, 2 and 2 times the height h of interpenetration of the longitudinal locking notches C1 and C2 in the first axial direction l-1.

In FIG. 9, the device 1 comprises covering profiles 15a to 15h which extend the locking profiles 8 to 11 so as to provide a visual impression of continuous glazing beads over the entire inner contour of the frame 6. The covering profiles 15a at 15h, however, extend much greater distances than those of interrupts 21, 22, 31, 32, 41, 42, 51 and 52. It is therefore necessary to be able to remove them easily by a traction movement in the second axial direction ll-ll away from the longitudinal wing 10.

To do this, a first possibility consists of a covering profile 15a to 15h as illustrated in FIG. 7, with a generally U substantially identical to that of the locking profiles 8 to 1 1. This covering profile 15a to 15h comprises first 12 'and second 13' branches defining between their inner faces 12b 'and 13b' a housing 14 'adapted to receive the longitudinal rib 1 10 of one of the lateral sections 2 to 5 of the frame 6. The inner faces 12b 'and 13b' of the first 12 'and second 13' branches are, however, devoid of any longitudinal locking bias.

A second possibility consists of a covering profile 15a to 15h as illustrated in FIG. 8, with a generally U-shaped cross-section substantially identical to that of the locking profiles 8 to 1 1. This covering section 15a to 15h comprises first 12 "and second 13" branches defining between their inner faces 12b "and 13b" a housing 14 "adapted to receive the longitudinal rib 1 10 of one of the lateral sections 2 to 5 of the frame 6. Only the face 12b "inner of the first leg 12" is provided with a fifth longitudinal locking latch C5 cooperating by interpenetration with the third longitudinal locking bias C3 of said longitudinal rib 1 10 when the longitudinal rib 1 10 of one of the lateral profiles 2 to 5 of the frame 6 is received in the housing 14 "between the first 12" and second 13 "legs

The inner face 13b "of the second tab 13" being devoid of longitudinal locking bias, it can perform a withdrawal of the trim section 15a to 15h without much effort. For example, it is possible to insert a tool between the closure plate 7 and the free end 12a "of the first tab 12 to make a lever and tend to disengage the fifth longitudinal locking bias C5 from the third longitudinal locking bias C3, before pulling the trim profile 15a at 15h away from the lateral section 2 to 5 by a movement illustrated by the arrow F2.

According to an advantageous possibility of the present invention, the frame 6 is adjustable in width L and / or height H. In this case, as illustrated in FIGS. 3, 4 and 9:

the ends of the lateral sections 2 to 5 of the frame 6 slide into corner pieces PA1 to PA4,

- Adjustment means 16 to adjust the length in which the ends of the side sections 2 to 5 enter the corner pieces PA1 to P A4.

To do this, the ends of the lateral sections 2 to 5 of the frame 6 are provided with an outgrowth 17 in the general shape of V by means of a tip 18 (FIGS. 10 and 11) with section 19 which fits into the base 9. The adjustment means 16 comprise, on the corner pieces PA1 to PA4, jaws 20 and 20 'forming between them a housing 23 substantially V-shaped whose width can be selectively modified by spacing or relative approximation of said jaws 20 and 20 '. The spacing of the jaws 20 and 20 'is adjusted by means of the screw 24 which is engaged through the jaw 20 in a smooth hole and is engaged in the jaw 20' in a threaded hole.

When the gap between the jaws 20 and 20 'increases, the protrusion 17 penetrates more into the V-shaped housing formed between the jaws 20 and 20', so that the end of a lateral profile 2 to 5 penetrates in a longer length by sliding in the corner piece PA1 to P A4. When the gap between the jaws 20 and 20 'decreases, the protrusion 17 exits more V-shaped housing formed between the jaws 20 and 20', so that the length that enters the end of a lateral profile 2 to 5 in the corner piece PA1 to PA4 decreases.

The adjustment means 16 thus make it possible to adjust the length in which the ends of the lateral sections 2 to 5 enter the corner pieces PA1 to PA4. Thanks to the screws 24, this adjustment is carried out continuously, which allows a perfect adaptation to the dimensions of the opening in the wall of the building.

In FIGS. 3, 5 and 9, it can be seen that the device 1 comprises a first face 1a intended to be oriented towards the outside of the building (FIG. 5) and a second face 1b intended to be oriented towards the inside of the building. building (Figures 3 and 9). The adjustment means 16 (the screws 24 in this case) are operable only by access to the second face 1b of the device 1 (Figure 3).

The device 1 has great utility for the temporary but reliable filling of an opening in the wall of a building that includes a window, French window or window that has been damaged. It is indeed advantageous in such a case to close quickly said opening to avoid any intrusion. And post a watch continuously for several days (the time to stock the components needed for repair) is very expensive, and sometimes not reliable enough.

When using the closure device 1 shown in Figures 1 to 5, the installer cuts a profile to obtain the lateral sections 2 to 5 so as to obtain a frame 6, after adding the end pieces 18 and interlocking parts angles PA1 to P A4, whose height dimensions H and width L are less than the dimensions of the opening to be closed.

The installer then installs the frame 6 in the opening by positioning it in the thickness of the wall of the building.

The installer then adjusts (increases) the dimensions of the frame 6 by the adjustment means 16 to press the lateral sections 2 to 5 against the inner periphery of the opening (also called table). Such a fixation makes it possible to avoid use anchoring elements in the table: this avoids unnecessary deterioration of the painting, which is very useful if it concerns, for example, an opening in the facade of a listed building .

The installer then delivers another profile to obtain the locking profiles 8 to 1 1. To do this, it provides distances D8 to D1 1 of elongation of the locking profiles 8 to 1 1 which are less than or equal to the distances D21, D22, D31, D32, D41, D42, D51 and D52 in which interrupts 21, 22, 31, 32, 41, 42, 51 and 52 extend.

The installer then adjusts the dimensions of the closure plate according to the final dimensions of the frame 6, then inserts it between the ribs 1 10 and bears against the inner surfaces 10b of the longitudinal wings 10.

The installer then installs the locking profiles 8 to 1 1. This installation can be done according to the first mode of manipulation previously described, that is to say:

- By respectively arranging the locking profiles 8 to 1 1 in one of the interruptions 21 or 22, 31 or 32, 41 or 42, 51 or 52, by placing the housing 14 in the extension of the longitudinal ribs, then

- By sliding the locking profiles 8 to 1 1 according to the elongation directions of the lateral sections 2 to 5, so as to penetrate the longitudinal ribs 1 10 in the housing 14, to bring the locking profiles 8 to 1 1 in their positions illustrated in Figure 3.

Alternatively, if the locking profiles 8 to 11 are provided with a certain elasticity, the installation can be done according to the second mode of manipulation described above, that is to say by a translational movement T (FIG. 2) in the second axial direction ll-ll causing a force insertion of the first 12 and second 13 tabs on either side of the rib 1 10 by elastic deformation of the locking profiles 8 to 1 1.

Note that more than one locking profile 8 to 1 1 can be installed on each lateral section 2 to 5.

The installer can then, optionally, add trim profiles 15a to 15h that he also delivers to customized lengths.

To then dismantle the frame 6, the installer begins by removing any cladding profiles 15a to 15h (by simply pulling for the trim profiles 15a to 15h of Figure 7, or by a lever effect followed by traction for the trim profiles 15a to 15h of Figure 8).

The installer continues by removing the locking profiles 8 to 1 1. To do this, he slides the locking profiles 8 to 1 1 into the interruptions 21, 22, 31, 32, 41, 42, 51 and 52, which has the effect of removing the ribs 1 10 housing 14. The locking profiles 8 to 1 1 can then be removed transversely effortlessly to the distance from lateral sections 2 to 5.

The installer then removes the shutter plate 7, then reduces the dimensions of the frame 6 using the adjustment means 16 to remove it from the masonry table of the opening. Finally, it separates the lateral sections 2 to 5 from corner pieces PA1 to P A4.

Most, if not all, of the elements can be reused later to seal an opening of equal or smaller dimensions.

It should be noted that the characteristics relating to the adjustment of the dimensions (height and width) of the frame 6 are independent of the shapes of the cross sections of the lateral profiles and the locking profiles. The characteristics relating to the adjustment of the dimensions (height and width) of the frame 6 thus form a distinct invention for which patent protection can be sought independently.

Although the present invention is presented in connection with a frame 6 of adjustable dimensions, it is nevertheless applicable to a frame of fixed dimensions, obtained for example by butt welding of the lateral sections 2-5 between them, taking care to spare interruptions 21, 22, 31, 32, 41, 42, 51 and 52 of the ribs 1 10.

A single interruption 21, 22, 31, 32, 41, 42, 51 or 52 on each rib 1 10 is possible. The interruption or interruptions 21, 22, 31, 32, 41, 42, 51 or 52 may be provided in other length sections of the ribs 1 10 (for example in the middle of the length of the ribs 1 10).

The lateral sections 2 to 5, 8 to 1 1 locking and / or dressing 15a to 15h can be manufactured, preferably by extrusion, various materials such as plastic (PVC in particular) or metal (aluminum in particular).
