Abstract

Device (1) for sealing an opening in the wall of a building, comprising four lateral profiles (2-5) forming between them a frame (6) for receiving and holding a closure plate ( 7) oriented in a plane (P1). The locking profiles (8-11) cooperate with longitudinal ribs (110) provided on the lateral profiles (2-5) to effectively retain the closure plate (7). The removal of the locking profiles (8-11) requires little effort due to interruptions (21, 22, 31, 32, 41, 42, 51, 52) of the longitudinal ribs (110) which allow withdrawal by longitudinal sliding of the locking profiles (8-11) relative to the lateral profiles (2-5).

Description

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

To close 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 closure 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 cover plate between the side profiles, we generally use glazing beads which are attached and fixed to the side profiles by snap-fastening. The glazing beads are often attached and fixed to the inside (i.e. facing the inside of the building) of the frame to make them inaccessible to intruders outside the building.

For security reasons against intrusions, it is necessary to ensure good retention of the cover plate in the frame. This requires a snap-fastening of the glazing beads according to a non-negligible, even significant, effort. Otherwise, a push on the cover plate, exerted from the outside of the building towards the inside of the building, could be enough to disengage the glazing beads and separate the cover plate from the frame.

The problem then arises that the greater the retention of the closure plate, the greater the mounting efforts by the installer must be significant in order to engage the glazing beads. At the same time, later dismantling of the glazing beads (to change the cover plate for example) becomes extremely difficult without damaging them.

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

To achieve these and other objects, the invention provides a device for closing an opening in the wall of a building, comprising four lateral profiles forming between them a frame for receiving and holding a plate. shutter oriented in a plane, said shutter plate having an edge and two opposite faces, in which:

6944FDEP ₅ docx

- at least two opposite lateral profiles of the frame each have a cross section comprising:

o a base, o a longitudinal wing extending, in a first axial direction substantially parallel to said plane, from the base towards the inside of the frame to a free end, said longitudinal wing comprising an internal surface intended to receive by support one of the two faces of said closure plate, a longitudinal rib extending from and away from said longitudinal wing in a second axial direction and located away from the base in the first axial direction, said longitudinal rib comprising a first face directed towards the base, said longitudinal rib comprising a second face opposite the first face and intended to receive in abutment the edge of said closure plate,

- The device comprises at least two locking profiles with a cross section in a general U shape comprising a first tab and a second tab ending in free ends, the first and second tabs defining between their internal faces a housing capable of receiving the rib longitudinal of one of the two opposite lateral profiles of the frame,

- the free end of the first tab is intended to bear against the other of the two faces of said closure plate,

- at least one of the first or the second face of the longitudinal rib has a first longitudinal locking notch,

- At least one of the first or second tab has on its inner face a second longitudinal locking notch cooperating by interpenetration with the first longitudinal locking notch of said longitudinal rib when the longitudinal rib of one of the two sections opposite side of the frame is received in the housing between the first and second legs,

- said locking profiles extend at respective first distances,

- The respective longitudinal ribs of said two opposite lateral profiles of the frame each comprise at least one longitudinal interruption at a second distance allowing the removal of a locking profile by a longitudinal sliding movement of said locking profile until the interruption.

6944FDF, P, docx

In the sense of the present invention, a longitudinal locking notch is understood as 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 locking notch coincides with the direction of elongation of the lateral profile or of the locking profile carrying said longitudinal locking notch.

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 (cross sections) providing a very large transverse retention capacity in order to effectively limit the risks of separation of the locking profiles from the lateral profiles by a transverse force induced by a thrust exerted on the cover plate from the outside of the building to the inside of the building.

Preferably, the first or the second longitudinal locking notch may comprise a plurality of longitudinal notches. This allows you to adjust the distance between the free end of the first leg and the inner surface of the longitudinal flange in order to adapt it to the thickness of the cover plate.

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

Preferably, it can be provided that:

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

the second longitudinal locking notch is disposed on the inner face of the second tab,

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

- A fourth longitudinal locking notch is disposed on the inner face of the first tab, said fourth longitudinal notching cooperating by interpenetration with the third longitudinal locking notch when the longitudinal rib of one of the two opposite lateral profiles of the frame is received between the first and second legs.

6944FDEP.docx

The third and fourth longitudinal locking notches 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 able to receive the longitudinal rib between their legs by a simple relative translational movement in 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 has at least the second longitudinal locking notch on the inside of the second tab, while each of the longitudinal ribs has at least the first longitudinal locking notch on its first face.

The elastic spacing of the free ends of the first and second legs one apart from the other 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 profile (induced by a push exerted on the cover plate from the outside of the building towards the inside 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 can allow reception of the second tab between the longitudinal rib and the base with little play in the first axial direction. One can in particular provide a clearance between 1.2 and 2 times the interpenetration height of the longitudinal locking notches in said first axial direction.

Advantageously, the closure device can comprise at least one covering profile with cross section in general U shape substantially identical to the cross section in general U shape of the locking profiles, with first and second branches defining between their faces. interior a housing adapted to receive the longitudinal rib of one of the two opposite lateral profiles of the frame, in which the interior faces of the first and second branches are devoid of any longitudinal locking notch.

Being devoid of any longitudinal locking notch on the inner faces of the first and second branches, the covering profile can

6944FDEP, docx be engaged and removed on the longitudinal rib by a simple translation in the second axial direction, without much effort. The covering profile allows an extension of the locking profile (s) to visually provide a impression of a single glazing bead constituted by the locking profile (s) and the profile (s) of dressing put end to end.

Preferably, it can be provided that:

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

- The device comprises at least one covering profile with cross section in the general shape of LJ substantially identical to the cross section in general U shape of the locking profiles, with first and second branches defining between their inner faces a housing capable of receive the longitudinal rib of one of the two opposite lateral profiles of the frame, in which only the inner face of the first tab is provided with a fifth longitudinal locking notch cooperating by interpenetration with the third longitudinal locking notch of said longitudinal rib when the longitudinal rib of one of the two opposite lateral profiles of the frame is received in the housing between the first and second legs.

Again, such a covering profile allows an extension of the locking profile (s) to visually give the impression of a single glazing bead formed by the locking profile (s) and the profile (s). (s) covering placed end to end. The fifth longitudinal locking notch allows the covering profile not to disengage inadvertently from the longitudinal rib and / or allows the covering profile to participate somewhat in the retention of the closure plate.

The fact that the inner face of the second tab is devoid of longitudinal locking notch allows removal of the trim profile without much effort. One can for example insert a tool between the closure plate and the free end of the first tab to pry and tend to release the fifth longitudinal locking notch from the third longitudinal locking notch.

According to another particular aspect of the present invention, the frame can be adjustable in width and / or in 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 opening urgently after a broken window or window.

Advantageously, it can be provided that:

6944FDEP, docx

- the ends of the side profiles of the frame slide into corner pieces,

- adjustment means make it possible to adjust the length by 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 construct approximately (therefore quickly) a frame to the dimensions of the opening by cutting off the lateral profiles and locking (and possibly covering). After assembling the side 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 good sealing.

Preferably, it can be provided that:

- the ends of the side profiles of the frame are provided with a protrusion in the general shape of a 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 force support of the frame against the masonry table according to very significant efforts.

Advantageously, provision may be made for the adjustment means to adjust the length over which the ends of the lateral profiles penetrate into the corner pieces continuously. Continuous adjustment allows 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 inside of the building,

- The adjustment means can be operated 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.

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

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

11.

At least two of the opposite lateral profiles of the frame 6 (lateral profiles 2 and 4 on the one hand, or lateral profiles 3 and 5 on the other hand, and preferably

6944FDEB, docx all side profiles 2 to 5) each have a cross section as illustrated in Figures 1 and 2. This cross section includes:

o a base 9, o a longitudinal wing 10 extending, in a first axial direction ll 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 comprising an inner surface 10b intended to receive by pressing one of the two faces 7b or 7c of said closure plate 7 (here the face 7b), o a longitudinal rib 110 extending from and away from said longitudinal wing 10 in a second axial direction ll-ll (which is here substantially perpendicular to said plane P1) and located away from the base 9 in the first axial direction ll, said longitudinal rib 110 having a first face 110a directed towards the base 9 , said longitudinal rib 110 comprising a second face 110b opposite to the first face 110a and intended to receive in abutment the edge 7a of said closure 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 11 on the other hand, and preferably all four). As illustrated in FIGS. 1 and 2, these locking profiles 8 to 11 have a generally U-shaped cross section comprising a first tab 12 and a second tab 13 ending in free ends 12a and 13a. The first and second legs 12 and 13 define, between their inner faces 12b and 13b, a housing 14 capable of receiving the longitudinal rib 110 of the lateral profiles 2 to 5 of the frame 6.

The free end 12a of the first tab 12 is intended to bear 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 110a or the second 110b face of the longitudinal rib 110 (here the first face 110a) has a first longitudinal locking notch C1.

At least one of the first 12 or the second 13 tab has on its inner face 12a or 13a (here the second tab 13 on its inner face 13a) a second longitudinal locking notch C2 cooperating by interpenetration with the first longitudinal notching C1 locking of said longitudinal rib 110 when the longitudinal rib 110 of one of the side sections 2 to 5 of the frame 6 is received in the housing 14 between the first 12 and second 13 legs. The longitudinal locking notches C1 and C2

6944FDEPJOCX cooperate to oppose a force F applied to the first face 7b of the closure plate 7.

It can be seen more particularly in FIG. 3 that said locking profiles 8 to 11 extend along first distances D8 to D11 respectively.

The respective longitudinal ribs 110 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 according to a second distance D21, D22, D31, D32, D41, D42, D51 and D52 authorizing the withdrawal of the locking profiles 8 to 11 by a longitudinal sliding movement of said locking profile 8 to 11 until the interruption 21, 22, 31, 32, 41, 42, 51 or 52.

In practice, to allow such withdrawals by longitudinal sliding, it is here provided 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 D11.

To adapt the thickness E of the closure plate 7 to the engagement of the locking profile 8 to 11 on the rib 110, the first longitudinal locking notch C1 comprises a plurality of longitudinal notches.

For its part, the second longitudinal locking notch C2 comprises a single longitudinal notch. The second longitudinal locking notch C2 could however also include 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 11 for the construction of a second embodiment of the shutter device 1, it can be seen that :

the first longitudinal locking notch C1 is disposed on the first face 110a of the longitudinal rib 110,

the second ionitudinal locking notch C2 is arranged on the inner face 13a of the second tab 13,

a third longitudinal locking notch C3 is arranged on the second face 110b of the longitudinal rib 110,

- A fourth longitudinal locking notch C4 is arranged on the inner face 12a of the first tab 12, said fourth longitudinal locking notch C4 cooperating by interpenetration with the third longitudinal locking notch C3 when the longitudinal rib 110 of one of the

6944FDEP., Docx lateral profiles 2 to 5 of the frame 6 is received between the first 12 and second 13 legs.

The presence of the third C3 and fourth C4 longitudinal locking notches improves the retention of the locking profiles 8 to 11 on the longitudinal ribs 110 against transverse forces.

In the two embodiments, the locking profiles 8 to 11 can, according to a first method of manipulation, be engaged on the ribs 110 of the lateral profiles 2 to 5 by a movement opposite to that leading to their removal, that is to say to say :

- by respectively placing the locking profiles 8 to 11 in one of the interruptions 21 or 22, 31 or 32, 41 or 42, 51 or 52, by placing the housings 14 in the extension of the longitudinal ribs 110,

- Then by sliding the locking profiles 8 to 11 in the directions of elongation of the side profiles 2 to 5, so as to penetrate the longitudinal ribs 110 into the housings 14, until bringing the locking profiles 8 to 11 in their positions illustrated in Figure 3.

The locking profiles 8 to 11 may also have a certain capacity for elastic deformation allowing an elastic spacing of the free ends 12a and 13a of the first 12 and second 13 legs, one away from the other.

In such a case, the locking profiles 8 to 11 can then be engaged on the ribs 110 of the lateral profiles 2 to 5 according to a second mode of manipulation consisting of a simple translation movement T relative in the second axial direction ll-ll ( figure 2). During such a translational movement T, an elastic spacing of the free ends 12a and 13a of the first and second 13 tabs occurs, one apart from the other which allows the reception of the longitudinal rib 110 in the housing. 14 provided between the legs 12 and 13.

It is therefore advisable to provide that each locking profile 8 to 11 comprises (as illustrated in FIGS. 1 and 2) at least the second longitudinal locking notch C2 on the inner face 13a of the second tab 13, while each of the ribs longitudinal 110 comprises at least the first longitudinal locking notch C1 on its first face 110a. Indeed, in the case of a force F on the closure plate 7, exerted from the outside of the building towards the inside of the building, it has been found that the locking profile 8 to 11 tends to deform by spacing elastic free ends 12a and 13a of the first 12 and second 13 legs one away from the other. During this deformation, the inner face 12b of the first tab 12 tends to move away from

6944FDEP, docx the distance from the second face 110b of the longitudinal rib 110 while the inner face 13b of the second tab 13 is pressed against the first face 110a of the longitudinal rib 110. Provide at least notches C1 and C2 as illustrated in FIGS. 1 and 2 therefore allows good cooperation of the locking profiles 8 to 11 with the lateral profiles 2 to 5 to effectively retain the closure plate 7.

It can be seen more particularly in FIGS. 2 and 6 that the gap EC between the longitudinal rib 110 and the base 9 in the first axial direction ll allows reception of the second tab 13 between the longitudinal rib 110 and the base 9 with little play J in the first axial direction ll. The clearance J can 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-l.

In FIG. 9, the device 1 comprises covering profiles 15a to 15h which extend the locking profiles 8 to 11 in order to provide a visual impression of continuous glazing beads over the entire inner contour of the frame 6. The covering profiles 15a to 15h, however, extend over distances much greater than those of interruptions 21, 22, 31, 32, 41, 42, 51 and 52. It is therefore necessary to be able to remove them easily by a pulling 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 at 15h as illustrated in FIG. 7, with a cross section in the general shape of U substantially identical to that of the locking profiles 8 to 11. This profile covering 15a at 3 p.m. includes first 12 ′ and second 13 ′ branches defining between their interior faces 12b ′ and 13b ′ a housing 14 ′ capable of receiving the longitudinal rib 110 of one of the lateral profiles 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 notch.

A second possibility consists of a covering profile 15a at 3 pm as illustrated in FIG. 8, with a cross-section in the general shape of U substantially identical to that of the locking profiles 8 to 11. This covering profile 15a at 3 pm has first 12 ”and second 13” branches defining between their internal faces 12b ”and 13b” a housing 14 ”capable of receiving the longitudinal rib 110 of one of the lateral profiles 2 to 5 of the frame 6. Only the internal face 12b ”Of the first tab 12” is provided with a fifth longitudinal locking notch C5 cooperating by interpenetration with the third longitudinal locking notch C3 of said longitudinal rib

6944FDEP.docx

110 when the longitudinal rib 110 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 "legs.

Since the inner face 13b "of the second tab 13" is devoid of longitudinal locking notching, it is possible to remove the covering profile 15a at 3 p.m. without much effort. We can for example insert a tool between the closing plate 7 and the free end 12a ”of the first tab 12 to pry and tend to release the fifth longitudinal locking notch C5 out of the third longitudinal locking notch C3, before pull the covering profile 15a at 3 p.m. away from the lateral profile 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 in height H. In the present case, as illustrated in FIGS. 3, 4 and 9:

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

- Adjustment means 16 make it possible to adjust the length along which the ends of the lateral sections 2 to 5 penetrate into the corner pieces PA1 to PA4.

To do this, the ends of the lateral profiles 2 to 5 of the frame 6 are provided with a protrusion 17 in the general shape of a V by means of an end piece 18 (FIGS. 10 and 11) with a section 19 which fits into the base. 9. The adjustment means 16 comprise meanwhile, 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 approximation relative 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 distance 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 along a greater length by sliding in the corner piece PA1 to PA4. When the distance between the jaws 20 and 20 'decreases, the protrusion 17 comes out more of the V-shaped housing formed between the jaws 20 and 20', so that the length along which penetrates 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 along which the ends of the lateral sections 2 to 5 penetrate into the corner pieces PA1 to PA4. Thanks to the screws 24, this adjustment is carried out continuously, which

6944FDEP, docx 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 ( Figures 3 and 9). The adjustment means 16 (the screws 24 in this case) can be operated only by access to the second face 1b of the device 1 (FIG. 3).

The device 1 is very useful for temporarily but reliably closing an opening in the wall of a building which includes a window, window or window which has been damaged. It is indeed advantageous in such a case to quickly close said opening to avoid any intrusion. And posting a watchman permanently for several days (the time to supply the components necessary for the repair) is very expensive, and sometimes not reliable enough.

When using the shutter device 1 illustrated in FIGS. 1 to 5, the installer cuts a profile to obtain the lateral profiles 2 to 5 so as to obtain a frame 6, after addition of the end pieces 18 and fitting into the pieces angles PA1 to PA4, the dimensions of which in height H and in width L are slightly 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 building wall.

The installer then adjusts (increases) the dimensions of the frame 6 by the adjustment means 16 to press the side profiles 2 to 5 against the inside periphery of the opening (also called a table). Such a fixing makes it possible to avoid resorting to anchoring elements in the table: this avoids unnecessarily damaging the table, which is very useful if it is for example an opening in the facade of a building classified as a historic heritage.

The installer then delivers another profile to obtain the locking profiles 8 to 11. To do this, it provides distances D8 to D11 for the extension of the locking profiles 8 to 11 which are less than or equal to the distances D21, D22, D31 , D32, D41, D42, D51 and D52 according to which the interruptions 21, 22, 31, 32, 41, 42, 51 and 52 extend.

The installer then adjusts the dimensions of the closure plate as a function of the final dimensions of the frame 6, then inserts it between the ribs 110 and bears against the interior surfaces 10b of the longitudinal wings 10.

The installer then proceeds to install the locking profiles 8 to 11. This installation can be done according to the first method of handling described above, that is to say:

6944FDEP.docx

- by respectively placing the locking profiles 8 to 11 in one of the interruptions 21 or 22, 31 or 32, 41 or 42, 51 or 52, by placing the housings 14 in the extension of the longitudinal ribs, then

- by sliding the locking profiles 8 to 11 in the directions of elongation of the lateral profiles 2 to 5, so as to penetrate the longitudinal ribs 110 into the housings 14, until bringing the locking profiles 8 to 11 into their positions illustrated in Figure 3.

As an alternative, if the locking profiles 8 to 11 are provided with a certain elasticity, the installation can be carried out according to the second method of manipulation described above, that is to say by a translational movement T (FIG. 2 ) in the second axial direction ll-ll causing a forceful insertion of the first 12 and second 13 tabs on either side of the rib 110 by elastic deformation of the locking profiles 8 to 11.

Note that more than one locking profile 8 to 11 can be installed on each side profile 2 to 5.

The installer can then, optionally, add cladding profiles 15a to 3 p.m. which he also cuts to tailor-made lengths.

To then dismantle the frame 6, the installer begins by removing any covering profiles 15a at 3 p.m. (by simple pull for the covering profiles 15a at 3 p.m. in Figure 7, or by a leverage effect followed by a pull for cladding profiles 15a to 15h in Figure 8).

The installer continues by removing the locking profiles 8 to 11. To do this, he slides the locking profiles 8 to 11 until interruptions 21, 22, 31, 32, 41, 42, 51 and 52, which has the effect of removing the ribs 110 from the housings 14. The locking profiles 8 to 11 can then be removed transversely without effort away from the lateral profiles 2 to 5.

The installer then removes the closure 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 side sections 2 to 5 from the corner pieces PA1 to PA4.

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 of the locking profiles. The characteristics relating to the adjustment of the dimensions (height and width) of the

6944FDEP.docx frame 6 thus form a separate 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 5, obtained for example by butt welding of the lateral profiles 2-5 together, taking care to provide interruptions 21, 22, 31, 32, 41, 42, 51 and 52 of the ribs 110.

A single interruption 21, 22, 31, 32, 41, 42, 51 or 52 on each rib 110 is possible. The interruption or interruptions 21, 22, 31, 32, 41, 42, 10 51 or 52 can be arranged in other sections of length of the ribs

110 (for example in the middle of the length of the ribs 110).

The lateral profiles 2 to 5, of locking 8 to 11 and / or of covering 15a to 3 pm can be manufactured, preferably by extrusion, in various materials such as plastic (PVC in particular) or metal (aluminum in particular).

The present invention is not limited to the embodiments which have been explicitly described, but it includes the various variants and generalizations thereof contained in the field of claims below.
