MULTIPLE GLAZING FOR CLOSING DEVICE

The present invention relates to multiple glazing, in particular insulating glass, intended to be integrated into a closing device such as a window, a door or the like. The invention also relates to an assembly comprising multiple glazing and a covering frame attached to the periphery of the multiple glazing, and to a closure device comprising such multiple glazing or such an assembly.

The invention relates generally to any closing device in which multiple glazing is used. A closing device comprises, on the one hand, a frame such as a window frame or a door frame, and on the other hand, at least one filling mounted on the frame, which can be mobile or fixed, such as '' a movable or fixed window sash or a door panel. The applications of closing devices comprising multiple glazing are numerous, in particular in the fields of building, transport, interior fittings, refrigerated cabinets, as a window, glazed door, glazed partition, sliding door, etc.

For a standard window or glazed door, the filling conventionally comprises multiple glazing which is taken into rebate on its periphery in a frame of joinery generally made of PVC, aluminum or wood. The multiple glazing comprises at least two sheets of glass assembled at their periphery using a rigid spacer frame, which define between them a cavity filled with a layer of air or insulating gas. The spacer frame is secured to the periphery of the glass sheets using sealing cords, generally based on polyisobutylene (butyl), which make it possible to produce a primary barrier for sealing against water vapor and gases . In order to increase the seal and mechanical strength of the multiple glazing, an external sealing barrier is also present around the entire outer periphery of the spacer frame between the sheets of glass.

Several standards and certifications, in particular the national and European standards and certifications NF EN 12211, NF EN 14608, NF EN 14609, AEV, ACOTHERM, define the tests and performance levels required for windows and doors, in particular in terms of performance. mechanical. Classic multiple glazing does not meet the requirements of these standards and certifications without using thick carpentry frames. Consequently, the effective surface of the closing device occupied by the joinery is large, which reduces the glazed surface and the light inputs through the closing device.

It is to these drawbacks that the invention more particularly intends to remedy by proposing multiple glazing having an increased contribution to the mechanical strength of a closing device in which it is integrated, such as a window, a door or the like. , the clear view of the multiple glazing being further preserved.

To this end, the invention relates to multiple glazing comprising:

a glazed module comprising at least one spacer frame fixed between two sheets of glass, and a sealing barrier on the outer periphery of the spacer frame between the two sheets of glass, the glazed module comprising two external sheets of glass between which is delimited a edge of the glass module, and

- at least one reinforcing profile along each side of the glazed module, characterized in that, on each side of the glazed module, the reinforcing profile is independent of the spacer frame and the side of the glazed module is taken in rebate by the profiled reinforcement which extends both opposite the edge of the glazed module and of an outer main face of each outer glass sheet.

In the context of the invention, the term "glass sheet" means any type of substrate suitable for use in multiple glazing. It can be a sheet of mineral glass, in particular an oxide glass which can be a silicate, borate, sulfate, phosphate, or the like. Alternatively, it may be an organic glass sheet, for example polycarbonate or polymethyl methacrylate.

Within the meaning of the invention, the edge of the glazed module designates the peripheral face of the glazed module, which is formed by the surface of each sealing barrier situated between two sheets of glass and the edges of the glass sheets, which may possibly be covered by material of the sealing barrier when this protrudes outside the space defined between the glass sheets.

In the context of the invention, the fact that each reinforcing profile is independent of the spacer frame means that the spacer frame and the reinforcing profile are not mechanically coupled together. There is a degree of freedom between each reinforcing profile and the spacer frame, which makes it possible to limit the transmission of mechanical forces to the primary sealing barrier when the multiple glazing is subjected to stresses at the level of its reinforcing profiles. . In practice, the mechanical decoupling between the spacer frame and each reinforcing profile is obtained by having a thickness of sealing material between them. The independence of each reinforcing profile vis-à-vis the spacer frame improves the durability of the multiple glazing, by dissociating the sealing function provided by the spacer frame and the mechanical resistance function provided by the reinforcing profiles.

In multiple glazing according to the invention, each side of the glazed module is rebated by a reinforcing profile. In the context of the invention, the expression “taken into rebate” is used in its conventional sense in the field of carpentry, namely that the reinforcing profile covers the side of the glazed module by going up along the main faces outer sheets of outer glass. The rebate grip height then corresponds to the height of the part of the reinforcing profile located opposite the main outside face of the external glass sheets.

Thanks to the invention, which involves reinforcing profiles independent of the spacer frame and the rebate on the sides of the glazed module by the reinforcing profiles, it is possible to obtain improved mechanical performance of the multiple glazing compared to those of existing multiple glazing, in particular in terms of wind resistance, bracing resistance, resistance to static torsion as defined in standards NF EN 12211, NF EN 14608 and NF EN 14609, without having to increase the thickness of the sealing barrier compared to that of existing multiple glazing.

The invention thus makes it possible to obtain multiple glazing which is mechanically reinforced without its clear view being affected. To form a filling of a closing device such as a window, a door or the like, such reinforced multiple glazing can be associated with a carpentry frame of reduced thickness, or even be used without a carpentry frame, so that the glazed area of the closing device is maximized, which increases the amount of light supplied through the closing device.

In an advantageous configuration, on each side of the glazed module, the height of the part of the reinforcing profile facing the external main face of each sheet of external glass is less than or equal to the height of the sealing barrier and of the spacer frame between the glass sheets of the glass module. A rebate height equal to the height of the sealing barrier and of the spacer frame corresponds to a maximum rebate taken by the reinforcing profile, and therefore to a maximum mechanical reinforcement of the multiple glazing, making it possible not to impact the light of view of multiple glazing.

According to one aspect of the invention, on each side of the glazed module, the reinforcing profile is embedded in the sealing barrier. Such embedding can be obtained by pressing a part of the reinforcing profile in the material of the sealing barrier while the latter is in an uncured state, so as to push the part of the reinforcing profile into it, then activating the hardening (in particular crosslinking) of the material of the sealing barrier so as to immobilize the part of the reinforcing profile in the sealing barrier.

According to another aspect of the invention, on each side of the glazed module, the reinforcing profile is bonded to the surface of the sealing barrier. The bonding of the reinforcing profile to the surface of the sealing barrier can in particular be carried out after the hardening (in particular crosslinking) of the material of the sealing barrier.

According to another aspect of the invention, on each side of the glazed module, the immobilization of the reinforcing profile results from a belting of the glazed module on its four sides using the reinforcing profiles. Such a belt can be obtained by positioning the reinforcing profiles along the four sides of the glazed module and by joining the reinforcing profiles at each corner of the glazed module using brackets.

Preferably, on each side of the glazed module, the reinforcing profile is bonded to the main outside face of each sheet of external glass. This contributes to maintaining an optimal positioning between the reinforcing profile and the side of the glazed module that it takes in rebate, and thus to increase the mechanical resistance of the multiple glazing.

In an advantageous embodiment, the bonding of the reinforcing profile on the outer main face of each outer glass sheet is carried out using the material of the sealing barrier which projects beyond the space defined between the glass sheets. , especially when the reinforcement profile is inserted into the sealing barrier.

According to an advantageous characteristic, on each side of the glazed module, the reinforcing profile defines a peripheral groove of the multiple glazing, capable of receiving functional elements of a closing device in which the multiple glazing is intended to be integrated. Such functional elements can be, in particular: a frame for covering the multiple glazing; connecting elements with a frame, such as hinges, sliding guide elements, etc. ; hardware items, such as bolts, strikes, etc.

The spacer frame of the multiple glazing may be made of metal and / or of polymeric material. Examples of suitable metallic materials include, for example, aluminum or steel. Examples of suitable polymer materials include, in particular, polyethylene (PE), polycarbonate (PC), polypropylene (PP), polystyrene, polybutadiene, polyesters, polyurethanes, polymethyl methacrylate, polyacrylates, polyamides , polyethylene terephthalate (PET), polybutylene terephthalate (PBT), acrylonitrile butadiene styrene (ABS), acrylonitrile styrene acrylate (ASA), styrene-acrylonitrile copolymer (SAN). Any combination or mixture of these materials is also possible, for example each profile of the spacer frame can be based on polypropylene comprising a frame constituted by a steel strip. When it is based on polymer material, the profile is advantageously reinforced with fibers, in particular glass or carbon fibers.

The outer sealing barrier of multiple glazing can be formed, in particular, from a resin chosen from polysulphides, polyurethanes, silicones, hot-melt butyls, or hotmelt butyls, and their combinations or mixtures. These sealing materials have good adhesion to the glass sheets and mechanical properties enabling them to maintain the glass components on the spacer frame.

Each reinforcing profile of the multiple glazing may be made of metal and / or of polymeric material. Examples of suitable metallic materials include, for example, aluminum or steel. Examples of suitable polymeric materials include, in particular, polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), acrylonitrile butadiene styrene (ABS), acrylonitrile styrene acrylate (ASA), the copolymer styrene-acrylonitrile (SAN), polytetrafluoroethylene (PTFE), or other rigid polymers. Any combination or mixture of these materials is also possible, for example each reinforcing profile can be based on polyvinyl chloride (PVC) associated with a steel frame. When it is based on polymer material, the reinforcing profile is advantageously reinforced with fibers, in particular glass or carbon fibers.

In a particular embodiment, the glazed module comprises two sheets of glass and a spacer frame fixed between the two sheets of glass. The edge of the glazed module is then formed by the surface of the sealing barrier between the two glass sheets and the edges of the two glass sheets, which may possibly be covered with material of the sealing barrier when it overflows out. of the space defined between the sheets of glass.

In another embodiment, the glazed module comprises at least three glass sheets and, for each pair of adjacent glass sheets, a spacer frame is fixed between the two glass sheets of the pair. In this embodiment, a triple glazing thus comprises two spacer frames each positioned between two adjacent glass sheets among the three glass sheets of the glazing; a quadruple glazing unit comprises three spacer frames each positioned between two adjacent glass sheets among the four glass sheets of the glazing unit; etc. The edge of the glazed module is then formed by the surface of each of the sealing barriers present for each pair of adjacent glass sheets and the edges of the glass sheets, which may possibly be covered by material of the sealing barriers when the latter overflows out of the space defined between the sheets of glass.

In another embodiment, the glazed module comprises at least three glass sheets and a single spacer frame fixed between the two external glass sheets of the glazed module, the or each central glass sheet of the glazed module being received in an internal peripheral groove of the spacer frame. In this embodiment, a triple glazing thus comprises a spacer frame with a groove, two external glass sheets being positioned on either side of the spacer frame and a central glass sheet being received in the groove of the spacer frame; a quadruple glazing unit comprises a spacer frame with two grooves, two external glass sheets being positioned on either side of the spacer frame and two central glass sheets being each received in a respective groove of the spacer frame; etc. The edge of the glazed module is then formed by the surface of the sealing barrier between the two outer glass sheets and the edges of the two outer glass sheets, which may possibly be covered with material of the sealing barrier when the latter extends beyond the space defined between the external glass sheets.

According to one aspect of the invention, each reinforcing profile has a generally U-shaped cross section, comprising a bottom which faces the edge of the glazed module and which defines a peripheral groove of the multiple glazing, and two lateral wings which are opposite the main external face of the two external glass sheets of the glazed module.

Advantageously, the bottom of the U-shaped part of each reinforcing profile can then comprise a protruding portion in the direction of the edge of the glazed module, adapted to be embedded in the sealing barrier, in particular by pressing the protruding part into the sealing barrier in the not yet hardened state.

In one embodiment, each reinforcing profile comprises two parts, each forming one of the two lateral wings, one of the two parts being of substantially S-shaped cross section defining a peripheral groove in the multiple glazing.

In an advantageous embodiment, each reinforcing profile is obtained by folding or cold profiling of at least one metal blank.

Another object of the invention is an assembly comprising multiple glazing and a covering frame attached to the periphery of the multiple glazing, the multiple glazing comprising:

- at least one spacer frame fixed between two sheets of glass,

- a sealing barrier on the outer periphery of the spacer frame between the two sheets of glass,

- at least one reinforcing profile along each side of the glazing, characterized in that each reinforcing profile is independent of the spacer frame and in that the covering frame is fixed to the multiple glazing by means of the reinforcement.

In such an assembly, each reinforcing profile can be embedded in the sealing barrier. As before, such embedding can be obtained by pressing part of the reinforcement profile in the material of the sealing barrier while the latter is in an uncured state, so as to push the part of the reinforcement profile into it, then by activating the hardening (in particular crosslinking) of the material of the sealing barrier so as to immobilize the part of the reinforcing profile in the sealing barrier.

Each reinforcing profile can also be bonded to the surface of the sealing barrier, the bonding of the reinforcing profile to the surface of the sealing barrier can in particular be carried out after the curing (in particular crosslinking) of the material of the sealing barrier. .

The immobilization of each reinforcing profile may also result from a belt on the four sides of the glazing using the reinforcing profiles, such belting can be obtained by positioning the reinforcing profiles along the four sides of the glazing and by joining the reinforcing profiles at each corner of the glazing using brackets.

According to an advantageous characteristic of an assembly according to the invention, each reinforcing profile defines a peripheral groove of the multiple glazing able to receive parts of the covering frame for fixing it on the multiple glazing.

In one embodiment of an assembly according to the invention, on each side of the glazing, the covering frame comprises lateral parts capable of cooperating with the reinforcing profile of the multiple glazing and a central part for locking the lateral parts by compared to the reinforcement profile. The central part can then define a groove capable of receiving functional elements of a closure device, in particular elements for connection with a frame, such as hinges, sliding guide elements, etc. ; or hardware items, such as bolts, strikes, etc.

Finally, the subject of the invention is a closing device such as a window, a door or the like, comprising multiple glazing or an assembly as described above.

- Figure 10 is a section similar to Figure 3 for a triple glazing according to a fifth embodiment of the invention comprising three sheets of glass and a single spacer frame.

The window 20 according to the invention shown in FIG. 1 comprises a sleeping frame 17 and a leaf 12 held on the sleeping frame by means of hinges 19, one of the hinges 19 being visible in FIG. 1. Conventionally , the sleeping frame 17 is designed to be secured to a supporting structure, in particular a wall or a partition of a building. The leaf 12 has an opening frame 13 and multiple glazing 11 as a filling.

It is usual to name the different main faces of the glass sheets of multiple glazing by numbers starting from Φ, the number Φ designating the external face of the glass sheet intended to be turned towards the outside.

Thus, for double glazing (Figure 1 to 8), the outer main face of the glass sheet 1 intended to be turned towards the outside bears the number Φ, the inner main face of the glass sheet 1 intended to be turned outwardly bears the number ®, the outer main face of the glass sheet 2 intended to be turned inward bears the number ®, the inner main face of the glass sheet 2 intended to be turned inward has the number @.

Similarly, for triple glazing (Figures 9 and 10), the outer main face of the outer glass sheet 1 intended to be turned towards the outside bears the number Φ, the inner main face of the outer glass sheet 1 intended to be turned towards the outside bears the number ®, the main face of the internal glass sheet 2 turned towards the sheet of external glass 1 bears the number ®, the main face of the internal glass sheet 2 turned towards the sheet of outer glass 3 bears the number ©, the inner main face of the outer glass sheet 3 intended to be turned inward bears the number ©, the outer main face of the outer glass sheet 3 intended to be turned towards the inside has the number ©.

In the first embodiment visible in FIGS. 1 to 3, the multiple glazing 11 is double glazing, comprising a glazed module 8 and four reinforcing profiles 9 each extending along one side of the glazed module 8 so forming a reinforcing frame around the glazed module 8. Only two sides 81, 82 of the glazed module 8 are visible in FIG. 1, it being understood that the structure of the multiple glazing 11 at each side of the glazed module is similar to that shown in detail for the side 81 in FIGS. 2 and 3. The glazed module 8 comprises two sheets of glass 1,2 parallel to one another, which are arranged opposite one of the other. The two glass sheets 1, 2 can have different thicknesses. The dimensions (surface, thickness of the glass sheets) are to be chosen according to the desired application.

The glazed module 8 also includes a spacer frame 4, which is fixed between the two glass sheets 1, 2 so as to keep the glass sheets 1, 2 at a distance from each other by forming a cavity 5. The cavity 5 is filled with insulating gas, which provides good thermal and acoustic insulation to the double glazing 11. As clearly visible in FIG. 3, the spacer frame 4 is located between the main faces © and Θ, located opposite screw of one another, of the two sheets of glass 1,2, at a peripheral part of these faces.

Each of the two glass sheets 1, 2 is linked to a side wall of the spacer frame 4 by means of a butyl sealing bead 6. The double glazing 11 also comprises an external sealing barrier 7 made of polysulphide resin, which is applied over the entire outer periphery of the spacer frame 4 between the two glass sheets 1,2, so as to hold the glass sheets 1,2 between them and on the spacer frame 4.

As clearly visible on the enlarged section of FIG. 3, which corresponds to the lower side 81 of the glazed module 8 but which is also valid for the three other sides of the module, each reinforcing profile 9 is independent of the spacer frame 4, by being separated from it by the sealing barrier 7. The side 81 of the glazed module is taken into rebate by the reinforcing profile 9, which extends both opposite the edge 86 of the glazed module and the main faces outside Φ, © glass sheets 1,2.

In this embodiment, as shown in FIG. 2, the height h ₉ of rebate grip on each side of the glazed module 8 by the associated reinforcing profile 9 is substantially equal to the height h ₇ of the sealing barrier 7. According to a variant, the height h ₉ of rebate taking up by each reinforcing profile 9 can be greater than the height h ₇ of the sealing barrier 7, which can make it possible to increase the mechanical reinforcement obtained for the double glazing 11, while preferably remaining less than or equal to the sum of the height h ₇ of the sealing barrier 7 and the height h ₄ of the spacer frame 4, so as to preserve the clear view of the double glazing 11.

As clearly visible in FIGS. 2 and 3, each reinforcement profile 9 has a generally U-shaped cross section, comprising a bottom 91 which faces the edge 86 of the glazed module 8, and two lateral wings 94 and 96 which are opposite, respectively, the main face Φ of the glass sheet 1 and the main face © of the glass sheet 2. The bottom 91 of each reinforcing profile 9 has a projecting portion 92, intended to be directed in direction of edge 86 of the glazed module 8, allowing the reinforcement profile 9 to be embedded in the sealing barrier 7. Each reinforcement profile 9 is advantageously obtained by cold profiling of a steel sheet.

In this embodiment, the joining of each reinforcing profile 9 with the corresponding side of the glazed module 8 is obtained by embedding the bottom of the profile 9 in the sealing barrier 7, by driving the projecting portion into the resin of the barrier. sealing 7 while it is in an uncured state, then activating the hardening of the resin. In addition, the lateral wings 94 and 96 of each reinforcing profile 9 are respectively linked to the main face Φ of the glass sheet 1 and to the main face © of the glass sheet 2 by bonding with the barrier resin. sealing 7, which overflows during the insertion of the projecting portion 92 into the resin of the sealing barrier 7 for the embedding of the profile 9. Thus, in this embodiment, the edge 86 of the glazed module 8 is formed by the surface of the sealing barrier 7 between the two glass sheets 1, 2 and the resin of the sealing barrier 7 which covers the edges of the two glass sheets 1,2.

As a variant, the bottom 91 of each reinforcement profile 9 may not be embedded in the sealing barrier 7. In particular, the bottom 91 of each reinforcement profile 9 can be secured to the edge 86 of the glazed module 8 by bonding to the surface of the sealing barrier 7 already in the cured state. In this case, the reinforcing profile 9 advantageously has a substantially flat bottom 91 facing the edge 86 of the glazed module 8, as is shown by way of example with the variants of FIGS. 4 and 6 where the reinforcing profile 9 does not does not have a projecting portion 92. According to another variant, as shown in FIGS. 5 and 6, the lateral wings 94 and 96 of the reinforcing profile 9 can be formed by non-contiguous folding or cold profiling in a non-contiguous form of steel sheet.

In another embodiment, the immobilization of the reinforcing profiles 9 around the glazed module 8 can be obtained mechanically, by belting the glazed module 8, by positioning the reinforcing profiles 9 along the four sides of the glazed module 8 and joining them two by two at each corner of the glass module 8, for example using brackets.

In contrast to the projecting part 92, the bottom 91 of each reinforcing profile 9 defines a peripheral groove 98 facing outwards, allowing the double glazing 11 to receive functional elements from the window 20. In this mode of embodiment, as clearly visible in FIG. 2, the groove 98 is used to allow the fixing of the opening frame 13 on the double glazing 11.

More specifically, the opening frame 13 is formed of four elements, each intended to come cover one side of the double glazing 11. Each element of the opening frame 13 is formed of three parts, comprising a central part 15 and two lateral parts 14 and 16 provided to come opposite, respectively, the main face © of the glass sheet 1 and the main face © of the glass sheet 2, overcoming the reinforcing profile 9. The lateral parts 14 and 16 are configured to be inserted in the groove 98 of the reinforcing profile 9, the fixing of the element of the opening frame 13 on the reinforcing profile 9 being obtained by locking the lateral parts 14 and 16 in the groove 98 using of the central part 15 which engages between the lateral parts 14 and 16, as clearly visible in FIG. 2.

The central part 15 of each element of the opening frame 13 defines a groove 22 open at the periphery of the opening frame, which is capable of receiving functional elements from the window 20. In particular, in the example shown in the Figure 2, the groove 22 receives a lever 18 of the window. Other functional elements of the window could of course also be housed in the groove 22, in particular elements for connection with the sleeping frame 17, such as the hinges 19, or other hardware elements for the window.

The presence of the reinforcing profiles 9 at the periphery of the double glazing 11 makes it possible both to mechanically reinforce the double glazing 11 and to attach thereto the opening frame 13, without the need to use pierced, shaped or thermally reinforced. In addition, due to the increased resistance of the glazing, the opening frame 13 may have a thinner thickness than the frames of the state of the art, which makes it possible to preserve the clear view of the glazing.

Depending on the level of mechanical resistance of the double glazing 11 obtained thanks to the reinforcing profiles 9, the opening frame 13 can be designed to have a role of additional mechanical reinforcement, allowing the window 20 to meet the requirements of standards, or although the opening frame 13 can only have a role of masking the edges of the double glazing 11. Such masking not only improves the aesthetics of the leaf 12, but also makes it compatible with the different types of materials sealing traditionally used in the manufacture of multiple glazing, including those which have a low resistance to aging under the effect of ultraviolet radiation, such as polysulphides or polyurethanes.

Alternatively, when the double glazing 11 has sufficient mechanical strength, it can be envisaged to use the double glazing 11 alone, without a sash frame, as a sash of the window 20. In this case, the groove 98 can be used to directly receive connection elements with the sleeping frame 17, such as the hinges 19, and / or hardware elements, such as a cremone bolt similar to the cremone bolt 18 in FIG. 2.

In the second embodiment shown in Figure 7, elements similar to those of the first embodiment bear identical references. The multiple glazing 11 of the second embodiment differs from that of the first embodiment only in that each reinforcing profile 9 comprises a body 93 made of polyvinyl chloride (PVC), or any other rigid polymer, extruded around the entire periphery of the glazed module 8 and associated with a steel frame 95. Such a bi-material structure of each reinforcing profile 9 makes it possible to limit the thermal conduction through the reinforcing profiles 9, and thus to improve the thermal performance of the window 20.

In the third embodiment shown in Figure 8, elements similar to those of the first embodiment bear identical references. In this third embodiment, each reinforcing profile 9 of the multiple glazing 11 consists of two separate parts 97 and 99, which are linked together at the bottom 91 of the reinforcing profile and which each form one of the two wings side 94 and 96 of the reinforcement profile. The part 97 of the reinforcing profile 9 has a cross section generally at S and defines a peripheral groove 98 allowing the double glazing 11 to receive functional elements from the window 20. In the example shown in FIG. 8, the groove 98 is used, as in the first embodiment, to allow the fixing of the opening frame 13 on the double glazing 11. For this purpose, the opening frame 13 comprises a main profile 14, of which a protrusion is configured to be immobilized in the groove 98, and a glazing bead profile 16 attached to the main profile 14.

In this third embodiment, each reinforcing profile 9 is fixed to the corresponding side of the glazed module 8 by bonding using an adhesive 10. Thus, the reinforcing profiles 9 can be attached to the glazed module 8 a once the manufacture thereof has been finalized and the sealing barrier 7 is in the cured state. More specifically, the bottom 91 of each reinforcing profile 9 is fixed by gluing using the adhesive 10 on the edge 86 of the glazed module 8 and the lateral wings 94 and 96 of each reinforcing profile 9 are fixed by gluing using the adhesive 10 on the main face Φ of the glass sheet 1 and on the main face © of the glass sheet 2.

In the fourth and fifth embodiments shown in Figures 9 and 10, elements similar to those of the first embodiment bear identical references. The multiple panes 11 of these two embodiments differ from that of the first embodiment in that they are triple panes, and not double panes.

In the embodiment of FIG. 9, the glazed module 8 comprises three glass sheets 1, 2, 3 where the glass sheet 2, called the central glass sheet, is located between the two other glass sheets, called the glass sheets. external glass 1, 3. The glazed module 8 also comprises two spacer frames 4, which are each fixed between two glass sheets, respectively the glass sheets 1, 2 and the glass sheets 2, 3, so as to keep them at distance from each other by forming two cavities 5. The two cavities 5 can have the same thickness or have different thicknesses, depending on the desired application of the triple glazing. For each spacer frame 4, each of the two glass sheets 1, 2 or 2, 3 is linked to the spacer frame by means of a butyl sealing bead 6. The glazed module 8 also comprises, to hold the glass sheets 1, 2, 3 together and on the spacer frames 4 ', two external sealing barriers 7 made of polysulphide resin applied respectively over the entire outer periphery of the spacer frame 4 between the two glass sheets 1, 2 and over the entire outer periphery of the spacer frame 4 between the two glass sheets 2, 3.

As shown in FIG. 9, the bottom 91 of each reinforcement profile 9 is fixed by bonding using an adhesive 10 on the edge 86 of the glazed module 8 and the lateral wings 94 and 96 of each reinforcement profile 9 are fixed by bonding using the adhesive 10 on the main face Φ of the glass sheet 1 and on the main face © of the glass sheet 3. As a variant, each reinforcing profile 9 may have portions projecting similar to the portions 92 of the first embodiment, adapted to be embedded in the material of the two sealing barriers 7, the attachment with the outer main faces Φ, © of the external glass sheets 1, 3 can then be obtained at the using the material of the sealing barriers 7 which protrudes when the projecting portions 92 of the profile are pushed in.

In the embodiment of FIG. 10, the glazed module 8 also includes three glass sheets 1, 2, 3 where the glass sheet 2, called the central glass sheet, is located between the two other glass sheets, called sheets of external glass 1, 3. The central glass sheet 2 here has a surface smaller than that of the two external glass sheets 1, 3, and the glazed module 8 comprises a single spacer frame 4, which is fixed between the two sheets of external glass 1, 3, while the central glass sheet 2 is received in an internal peripheral groove of the spacer frame 4, with the interposition of a polymeric lining which is positioned in the groove to receive the edge of the central glass sheet 2 The glass sheets 1, 2, 3 are thus kept at a distance from each other by forming two cavities 5. As before, the two cavities 5 can have the same thickness or have different thicknesses, depending on the desired application. tr iple glazing. Each of the two external glass sheets 1, 3 is linked to the spacer frame 4 by means of a butyl sealing bead 6. The glazed module 8 also includes an external sealing barrier 7 made of polysulphide resin, which is applied over the entire outer periphery of the spacer frame 4 between the two external glass sheets 1, 3, so as to hold the glass sheets 1,3 between them and on the spacer frame 4.

The invention is not limited to the examples described and shown.

In particular, as mentioned above, multiple glazing according to the invention is not necessarily associated with an opening frame, or covering frame, when its mechanical strength is sufficient for it to meet the requirements of the standards alone. , which may be the case in particular when the rebate height of the sides of the glazed module by the reinforcing profiles is high.

In parallel, for an assembly according to the invention comprising multiple glazing and a covering frame attached to the periphery of the multiple glazing, there is not necessarily a need for rebating on the sides of the glazing by the reinforcing profiles. , because the covering frame can then contribute to the mechanical resistance of the assembly.

In practice, whether or not there is rebate on the sides of the glazing by the reinforcement profiles, the geometry of the section of each reinforcement profile is chosen to give the profile a high mechanical inertia. Examples of geometries with high inertia for the reinforcing profiles have been shown in the figures, it being understood that the invention is not limited to these examples.

Furthermore, the invention has been described for multiple glazing units comprising two or three sheets of glass, but it is also applicable to multiple glazing units comprising more than three sheets of glass. The materials of the constituent elements of multiple glazing may also be different from those described above. In particular, the barrier (s) for sealing multiple glazing according to the invention can be made of any sealing sealant conventionally used for manufacturing the secondary sealing barrier for multiple glazing, such as polysulphides, polyurethanes, silicones, hot melt butyls, etc.

Finally, the invention has been illustrated in the case of a window device. The invention can however be used for any type of closing device, of the window, door or similar type. In addition, the or each multiple glazing of the closing device can be mounted in different ways on the frame, for example by rotation, by sliding, etc.
