Description

TECHNICAL AREA

The present disclosure relates to a glazing unit and in particular to an insulating glazing unit (in particular a double or triple glazing unit) of the type comprising a first pane and a second pane that are parallel and separated by a spacer frame delimiting a sealed spacer space between said panes.

The present disclosure relates, more specifically, a glazing of this type equipped with a break detector of the glazing.

BACKGROUND OF THE INVENTION

Insulating glazing is commonly used to improve the thermal insulation of buildings and dwellings.

The interspace between the two panes forms an insulating blade of air or a less heat-conducting gas than air, for example argon, which makes it possible to limit the losses due to conduction or convection.

Insulating glazing units can be broken in the event of a shock due, for example, to weather conditions or acts of vandalism.

Several alarm systems have been developed to detect the deterioration of glazing as quickly as possible.

The most common system consists in providing, on the outer surface of the windows, one or more case detectors connected by cables to a control and control unit. The presence of cables makes the installation unsightly and complicated, the cables of each window must be connected to the same control unit.

More recently, it has been envisaged to integrate in the intermediate space, a case detector as well as a battery and an electronic system connected by a wireless link to a remote control and control unit. Such glazing is described in the international patent application WO2015 / 154688 . However, the integration of the electronic system and the battery in the intercalated space makes maintenance operations impossible, in particular the replacement of the battery, the life of which rarely exceeds ten years, or the replacement of the electronic system in the event of a failure. one of its components. Moreover, the presence of the electronic system and the battery inside the intermediate space hinders the clear view of the glazing. Finally, the electronic system and the battery can be damaged due to heating inside the intermediate space in the event of exposure of the glazing to the sun. Other arrangements of case detectors for double glazing are known from CN201963149 , EP2341490 or DE2933371 .

OBJECT AND SUMMARY OF THE INVENTION

One of the objectives of the present invention is to provide glazing to solve the aforementioned problems.

• une première vitre et une deuxième vitre parallèles et séparées par un cadre espaceur délimitant un espace intercalaire étanche entre lesdites vitres,
• au moins un détecteur de casse disposé à l'intérieur de l'espace intercalaire,
• un système électronique, et
• une batterie reliée au système électronique,

le vitrage étant caractérisé en ce que la batterie et le système électronique sont situés à l'extérieur de l'espace intercalaire, entre la première et la deuxième vitre, et
en ce que le vitrage comprend en outre des moyens d'extraction hors du vitrage d'au moins un composant électrique à extraire parmi la batterie et le système électronique.This objective is achieved with a glazing comprising

• a first pane and a second pane parallel and separated by a spacer frame defining a sealed spacer space between said panes,
• at least one case detector disposed within the interspace,
• an electronic system, and
• a battery connected to the electronic system,

the glazing being characterized in that the battery and the electronic system are located outside the intermediate space, between the first and the second pane, and
in that the glazing further comprises extraction means out of the glazing of at least one electrical component to be extracted from the battery and the electronic system.

The glazing according to the invention is not limited to double glazing comprising only two panes, but can be any type of multiple glazing.

In the present disclosure, a window may be a transparent sheet, in other words a sheet having the property of allowing light to pass (actually transparent in the sense that objects can be clearly distinguished through, or translucent) or an opaque sheet . Each window can be made of any suitable material or combination of materials, especially glass and / or plastic. At least one, and in particular each, pane may in particular be a glass sheet.

The glazing according to the invention makes it possible to integrate all the electrical components necessary for the detection of breakage inside the glazing, while maintaining a good aesthetic of the latter and ensuring easy maintenance.

The battery and the electronic system being located outside the sealed spacer space of the glazing, they do not obstruct the clarity of view.

Moreover, the battery and / or the electronic system can easily be extracted from the glazing to be replaced.

By extraction means of a component means here means for extracting said component to the outside of the glazing, without deterioration of said glazing.

• soit des moyens d'extraction de la batterie seule
• soit des moyens d'extraction du système électronique seul
• soit des moyens d'extraction de la batterie et du système électronique, ces moyens pouvant opérer pour l'extraction indépendante de la batterie et du système électronique, ou pour leur extraction conjointe.

The extraction means of the glazing may comprise:

• either means of extraction of the battery alone
• either means of extraction of the electronic system alone
• or means for extracting the battery and the electronic system, these means being able to operate for the independent extraction of the battery and the electronic system, or for their joint extraction.

In a preferred manner, however, the extraction means comprise at least battery extraction means, the battery generally to be changed at least every ten years, as explained above.

According to one example, the first and the second pane extend beyond the spacer frame away from the intermediate space, forming a first free (glass) border and a second (glass) free edge located opposite the spacer one of the other and defining between them a functional space, and the or each electrical component to be extracted is located in the functional space.

A free edge may extend all along at least one side of the glazing, but it may also be more localized, depending on the shape defined by the spacer frame.

In one example, the glazing further comprises a housing disposed in the functional space, the or each electrical component to be extracted being housed in said housing.

In this case, the housing is advantageously held in position within the functional space by fixing means. For example, the functional space may be filled with a sealant encasing the housing.

In one example, the battery and / or the electronic system are located in the functional space, preferably in a housing as defined above, preferably in the same housing.

Alternatively, the battery may be located in a housing, and the electronic system may be integrated within a corner connector or a profile forming the spacer frame provided for this purpose.

The extraction means typically comprise at least one extraction opening allowing extraction from the glazing of the at least one electrical component to be extracted.

The extraction means may comprise lateral extraction means, that is to say by the edge (i.e. the slice) of the glazing. In this case, the lateral extraction opening is typically formed on the side of the glazing between the first and the second free edge.

According to another example, the extraction means may comprise front extraction means. In this case, the front extraction opening is for example a notch made in the first or the second free edge.

The extraction means, whether lateral or front extraction means, advantageously comprise a system for expelling the electrical component to be extracted, in particular a spring or lever expulsion system.

The case detector can be of various natures. The at least one case detector may in particular comprise a humidity sensor, or a mechanical sensor, in particular a piezoelectric sensor, or the like.

According to an advantageous aspect of the invention, the case detector is connected by a flat connector to the electronic system. The use of a flat connector ensures the transfer of data without impeding the tightness of the functional space. Its thickness is small, typically between 50 and 500 microns, preferably between 100 and 200 microns. The flat connector typically comprises a conductive sheet (for example of a metal such as copper) sandwiched between two polymer sheets, and bonded to each of these by a thin layer of adhesive. The polymer sheets are typically polyimide or a polyester such as polyethylene terephthalate (PET) or ethylene polynaphthalate (PEN). The flat connector may comprise at least one of its ends a connection pin for establishing a removable connection with the system to which it is connected. Preferably, the flat connector comprises such an end connection pin which is connected to the electronic system, so as to allow the latter to be replaced. However it is preferable for reasons of simplicity of assembly, to provide a direct and permanent connection with the case detector, therefore without the intermediary of a connection pin.

According to an exemplary embodiment, at least one photovoltaic module is disposed inside the interspace. The photovoltaic module is generally connected to the battery via the electronic system.

In another example, the glazing comprises means for charging the battery by magnetic induction.

According to yet another example, the glazing comprises means for recharging the battery by Seebeck or thermoelectric effect, adapted to transform the temperature differential between the two faces of the glazing defining the interspace (faces 2 and face 3 of the glazing) in electric energy.

In one example, the glazing further includes a heat sink disposed in the functional space, preferably in the housing. The heat sink is generally in contact with the outer face of the glass located inside the building (face 3 of the glazing). The heat sink may for example be in the form of a heat conducting element, in particular copper, having a plurality of cooling fins. In this way, the temperature at which the electronic system and the battery are exposed can be kept close to the ambient temperature in the room.

The present disclosure also relates to a bay closure element comprising a glazing frame (for example a sash frame) and a glazing unit as defined above mounted in said glazing frame.

The bay closure member may for example be an opening adapted to cooperate with a frame of a dormant closing device such as a window, a door or the like.

The bay closure member may also be a stationary member.

In one example, the glazing frame does not cover the extraction opening of the glazing.

In this case, and if the extraction means comprise front extraction means, then the glazing may comprise a masking tape intended to hide the electronic system and / or the battery. A masking tape is typically printed by screen printing and made on the face of at least one of the panes. Preferably, a masking band is formed on each of the two panes, the two bands thus produced being located facing one another.

In another example, the glazing frame covers the extraction opening of the glazing.

In this case, the glazing frame preferably has an aperture adapted to allow access to the at least one component electrical to extract from the battery and the electronic system of the glazing, which can be extracted from the glazing.

The access opening of the glazing frame is then located opposite the extraction opening of the glazing and dimensioned to allow the extraction of the at least one electrical component.

Several modes or examples of embodiments are described in this presentation. However, unless otherwise specified, the features described in connection with any one embodiment or embodiment may be applied to another embodiment or embodiment.

DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS

• une vitre ou feuille de verre extérieure 11 (voir figures 2 et 3), typiquement destinée à être tournée vers l'extérieur d'un bâtiment,
• une vitre ou feuille de verre intérieure 12 (voir figures 2 et 3), typiquement destinée à être tournée vers l'intérieur du bâtiment et parallèle à la vitre extérieure 11,

• une batterie 60 reliée au système électronique 50 et destinée à alimenter électriquement ce système.

The Figures 1 to 3 illustrate a double glazing 10 according to a first embodiment of the present invention, comprising

• an outer glass or sheet of glass 11 (see Figures 2 and 3 ), typically intended to be turned towards the outside of a building,
• a glass or inner sheet of glass 12 (see Figures 2 and 3 ), typically intended to be turned towards the interior of the building and parallel to the outer pane 11,
• a spacer frame 14 extending continuously along the edge of the first and the second pane 11, 12, a sealed spacer space 16 being delimited by the spacer frame 14 between the two panes 11, 12,
• a case detector 40 disposed inside the interspace 16,
• an electronic system 50 connected to the case detector 40 and adapted to transmit a signal (in particular a radio signal) to an external control and control unit (not shown) in case of detection of a breakage by the case detector 40, and
• a battery 60 connected to the electronic system 50 and intended to power this system electrically.

It is usual to name the main faces of the windows of a double glazing by numbers ranging from 1 to 4. Thus, the outer face of the outer pane 11 facing the outside of the building bears the number 1, the inner face of the outer pane 11 facing the inner sheet 12 has the number 2, the outer face of the inner pane 12 facing the outer sheet 11 is numbered 3 and the inner face of the inner pane 12 facing the inside of the building door number 4, as shown in the figures.

A main direction X of the glazing 1, is perpendicular to the main faces respectively 1, 2 and 3, 4 of the two panes 11, 12. It generally corresponds to the direction of vision through the glazing,

A direction orthogonal to the main direction X is a so-called lateral direction of the glazing.

For each window, it is possible to define a longitudinal direction Z and a transverse direction Y, orthogonal to each other, and to the main direction X.

Each window generally has two longitudinal sides, parallel, extending in the longitudinal direction Z, and two transverse sides, parallel, extending in the transverse direction Y.

In the present discussion, a front displacement or extraction must be understood as a displacement or an extraction in the main direction X of the glazing.

Similarly, a displacement or lateral extraction (e) is a displacement or an extraction in a lateral direction of the glazing, in particular in the longitudinal direction Z or transverse Y.

The spacer frame 14 of the glazing 10 forms a continuous and closed on itself, of any shape, here rectangular, defining the spacing between the two panes and delimiting the interspace 16.

In the example, the spacer frame 14 is formed of four straight profiles 18 typically made of metal, for example aluminum or steel, or composite material, for example a combination of plastic and a metal film. They may have transverse sections (ie sections in a plane orthogonal to their main direction of extension) in U, V or C. They may also have a generally tubular shape, as illustrated in FIG. figure 3 , and be filled with a moisture-absorbing agent (represented in figure 3 in the form of small balls).

The profiles 18 can be connected by corner connectors.

Alternatively, the spacer frame 14 may also be formed of one or more bent sections at the corners. One or more junction pieces, sealed (s) with a caulking product, allows (in this case) to ensure the continuity of the seal.

According to another variant, the profiles can also be welded together.

Conventionally, a mastic bead 21, 22, generally butyl, is provided between each side of the spacer frame 14 and each glass sheet 11, 12. During manufacture, mastic cords 21, 22 are preferably deposited on the sides of the spacer frame 14, the frame covered with putty is first placed on a sheet 11 previously washed, the second sheet of glass 12 is attached to the spacer frame, and the assembly is secured in a press. Putty beads 21, 22 allow both to secure the spacer frame 14 to the glass sheets 11, 12 to seal the insulating glass 10, and to achieve a first barrier gas and water vapor.

A sealant, for example polyurethane, polysulfide or silicone, also forms a seal 24 between the glass sheets 11, 12 of the insulating glazing unit 10, outside the spacer frame 14, which makes it possible to produce a second barrier against gas and water vapor.

In the particular example shown, the first and second glass sheets 11, 12 extend beyond the spacer frame 14 and the second sealing barrier formed by the seal 24, away from the spacer space 16 , forming a first free edge 31 and a second free edge 32 facing each other and delimiting between them and with the spacer frame 14, a functional space 34.

The first and second free edges extend here all along the upper transverse edge of the glazing. According to other examples, Figures 8 and 9 which will be described in the following, the functional space 34 can also be more localized.

In the example, a housing 36 is housed in the functional space 34. To keep it in position, the housing 36 is coated with a sealant 38 of the same type as that forming the second sealing barrier 24, or of a different type, filling the functional space 34 between the first and the second free edge 31, 32.

The housing 36 houses the electronic system 50 and the battery 60.

Advantageously, it also houses a passive heat sink 70 here in the form of a finned copper block. In case of strong sunlight, the temperature inside the insulating glass 10 can reach 70 ° C, sometimes even 90 ° C, which can impact the life of the electronic system 50. The heat sink 70, put in contact with the electronic system 50 and / or one of the glass sheets 11, 12, protects the electronics and lower the temperature inside the glazing 10.

According to the invention, a case detector 40, here a humidity sensor, is housed inside the interspace 16.

When the gas inside the glazing 10 is a gas that is inherently heavier than air, as is the case with argon which is commonly used in double glazing, the humidity sensor 40 is advantageously located in the upper part of the glazing 10 in the use position. The air that enters the intermediate space 16 in case of breakage of the glazing being lighter than the gas initially present in this space, it is located primarily in this upper part of the glazing, and the moisture it contains can thus be more easily detected by the humidity sensor 40.

The humidity sensor 40 is connected to the electronic system 50, housed in the housing 36, by a flat connector 42, partly embedded in one of the cords of mastic 21, 22 making the first seal. The electronic system 50, powered by the battery 60, is intended to remotely transmit the information from the sensor 40, to a control and control unit, for example by a bluetooth link (not shown).

In the example, the battery 60 is powered by a photovoltaic module 64 disposed inside the intermediate space 16 and connected to the electronic system 50 by a flat connector 62, also partially embedded in one of the cords of mastic 21 , 22 realizing the first sealing.

This example is not, however, limiting. Alternatively, the glazing 10 may for example comprise means for charging the battery 60 by magnetic induction. The battery 60 is connected to a receiver adapted to cooperate with a transmission medium (charger) external to the glazing, transmitting power remotely (standard Qi), located on the electronic system.

According to another example, the glazing comprises means for recharging the battery by Seebeck or thermoelectric effect, adapted to transform the temperature differential between the two faces of the glazing delimiting the interspace (face 2 and face 3 of the glazing) into energy. electric.

In the example shown, the glazing 10 comprises means for extracting the battery 60. In other words, the battery 60 is mounted in the glazing 10 removably, and can be removed to be changed.

The extraction means of the battery 60 are here lateral extraction means, that is to say by the edge (i.e. the slice) of the glazing.

The housing 36 thus has an opening 36a directed towards the outside of the glazing 10, in a lateral direction (here transversal), and allowing the output of the battery 60.

As illustrated on the figure 2 , an ejection system 26 is also provided inside the housing 36. In the example, the ejection system 26 comprises an ejection lever 27 pivoting about an axis C. A first end 27a of the lever 27 is secured to a support 28 on which is mounted the battery 60. A second end 27b of the lever 27 is integral with an ejection rod 29 accessible from outside the glazing 10. When a pressure is applied on the ejection rod 29 (towards the inside of the glazing) , the lever 27 is actuated (pivoted about its axis C) and the battery holder 28 is moved outwardly of the glazing 10, moving at the same time the battery 60, which can then be extracted easily.

The example described above and illustrated on the Figures 1 to 3 however, is not limiting.

The glazing unit 10 may also, in addition, include extraction means of the electronic system 50. The electronic system 50 can thus be removed and changed or repaired in the event that one of its components does not work. In this case, the means may be identical or different from the extraction means of the battery 60. According to a preferred embodiment, these means may be means for jointly extracting the battery and the electronic system.

Furthermore, the ejection means are not limited to a lever system and may for example comprise a spring system or any other suitable system.

Also, the extraction of the battery can be frontal, that is to say carried out by one of the main faces of the glazing, and no longer by singing.

The figure 4 illustrates a glazing unit 10 according to a second embodiment, comprising front extraction means of the battery 60.

Elements identical or similar to those exposed in connection with the Figures 1 to 3 are not described again.

The housing 36 here has an opening 36b oriented towards one of the glass sheets 11, 12, here the inner glass sheet 12, and dimensioned to allow the extraction of the battery 60.

An extraction aperture 32b is furthermore made in the border 32 of the inner glass sheet 12, facing the opening 36b of the housing 36 and the battery 60.

The extraction opening 32b is, for example, a notch made at the edge of the glass sheet 12. As a variant, it could also be a closed contour opening, remote from the edge of the sheet.

Also, the opening 32b could be closed by a removable hatch.

Also, as illustrated on the figure 5 , the glazing unit 10 may comprise means for extracting the electronic system 50, in particular means extraction independent of those of the battery, and in particular ejection means 26 'of the same type as previously described.

As in the previous embodiment, the extraction means may for example include a lever-type or spring-type ejection system.

The Figures 6, 7 , 8 and 9 illustrate sections of window elements according to three exemplary embodiments.

According to these examples, each window element is an opening comprising a filling (the glazing), and a glazing frame 80, here an opening frame, maintaining said glazing. The frame is typically provided with a primary wall 81 and a secondary wall 82 facing one another, adapted to bear respectively against the outer face and the inner face of the glazing, and connected by a base 83 forming the frame's song. The two primary and secondary walls 81, 82 and the base 83 define the receiving housing of the glazing.

On the figure 6 , the window element comprises a glazing frame and glazing as defined above in connection with the Figures 1 to 3 .

The base 83 of the glazing frame is here provided with an access opening 84a located opposite the extraction opening and dimensioned to allow the extraction of the battery 60 (and the electronic system 50, if applicable). ).

Advantageously, for aesthetic reasons, the access opening 84 of the glazing frame can, in normal use, be closed by a removable shutter 85a, the shutter 85a being open or removed at the time of extraction and then closed or reset in place after battery maintenance is complete. The shutter is for example a hatch, as represented in FIG. figure 6 , or a plug.

In the embodiment of the figure 7 , the glazing 10 is a glazing unit of the type described in connection with the figure 4 which comprises front extraction means of the battery 60.

When the glazing 10 is mounted in the glazing frame 80, as shown in FIG. figure 7 , the extraction opening 32b formed in the inner pane 12 is covered by one of the walls, here secondary, 82 of the frame 80.

To allow the extraction of the battery, the glazing frame 80 is provided with an access opening 84b located on said wall 82, facing the extraction opening 32b. For aesthetic reasons, the opening 84b of the glazing frame can also be closed by a removable shutter 85b.

In the embodiment of Figures 8 and 9 , the glazing also includes front extraction means of the battery 60.

In this case, however, unlike the embodiment of the figure 7 the extraction opening 32b is not covered by the glazing frame 80.

The spacer frame here forms a recess at one corner of the pane, defining a first and a second free edge respectively of the first and second pane 11, 12, and, between these two borders, a functional space 34 housing a housing 36 in which are housed the battery and the electronic system.

Because of the recess, most of the spacer can be hidden by the glazing frame, only the "unhooked" part being located in the glazing clear.

For aesthetic reasons, the extraction opening 32b is here provided with a removable shutter 33 (see figure 9 ).

Alternatively, the shutter 33 could also be omitted, leaving the electronic system and battery visible and free access.

In the example, the glazing also comprises two masking strips 90, 92 made respectively on the inner face of the outer glass sheet 11 and on the outer face of the inner glass sheet 12. These strips 90, 92 are typically printed by screen printing (see figure 9 ).
