    [0001] The invention relates to the realization of a lateral glazing of a means of transport, and in particular a glazing of a train, said glazing being a multiple glazing, fixed, possibly to working window. Such glazing usually comprises: an outer substrate having an outer face facing an outer space, an intermediate face opposite the outer face, and a peripheral edge, an inner substrate having an inner face which faces an interior space, an intermediate face opposite the inner face, and a peripheral edge, and a glazing frame structure which holds the outer substrate and the inner substrate together so that the glazing separates said outer space from said interior space with a glazing cavity located between the outer substrate and the inner substrate. In the case where the glazing is openable, said outer substrate and said inner substrate each comprise, in an upper part, a hole opening on each face of the substrate and separated from the peripheral edge of the substrate, the holes of the substrates facing each other. -vis one of the other, to allow to realize the openable window and the glazing frame structure further maintains the two substrates around the holes.
    [0002] In order for this glazing to be an emergency exit, it also comprises a lamination comprising, on the one hand, at least one main glass-glass sheet and, on the other hand, a main plastic sheet, said main plastic sheet being located in contact (without gap) between firstly the intermediate face of said outer substrate and secondly the main glass sheet. The prior art also known from the European Patent Application No. EP 2 363 284, and in particular from the variant of Figure 2, a side glazing structure of transport means, this glazing being multiple, fixed, 3034041 - 2 - safety and emergency exit, without a working window. This document presents a solution to facilitate the breakage of the glazing, and thus facilitate evacuation. In this document, it is proposed that a reinforcing lamination of a substrate of the glazing unit is not in contact with a peripheral glazing frame structure by providing that this lamination is set back from this peripheral structure. The prior art discloses the Chinese utility model No. CN 202788522, a fixed multiple glazing window of multiple transport means, with an openable window. This glazing has a satisfactory aesthetics thanks to the substrates each provided with a rectangular hole to make the window open. This glazing has a satisfactory thermal insulation capacity 15 thanks to the presence of the glazing cavity between the two substrates. However, this glazing does not constitute so-called "security" glazing because the glass substrates, even if one or both of them has or has undergone a chemical or thermal treatment intended to strengthen it, does not make it possible to produce a glazing unit. in the sense that if an object hits one of the substrates and breaks it, it means that this object is very likely to have enough energy to break the other substrate and thus break the glazing completely. Only a lamination, comprising at least one plastic sheet and then a sheet of glass which are provided in this order on a surface of a substrate, makes it possible to produce a safety glazing. Such safety glazing is more resistant to shocks, while allowing evacuation if necessary by cutting the plastic sheet. The object of the invention is to make it possible to produce a fixed multiple glazing, possibly with an openable window, which has a facility of destruction in an external part, while allowing this outer part to be held in position if it is broken involuntarily. The invention thus rests on the fact of providing a reinforcement lamination in the outer part of glazing (and in the outer part of glazing 3034041 - 3 - located under the working window if there is one), and to provide in besides means for maintaining this lamination attached to the glazing if this lamination is broken involuntarily. The object of the invention is, in its widest sense, a lateral glazing of a transport means, in particular a train glazing, said glazing being a fixed multiple glazing, said glazing comprising: an outer substrate having an outer face which faces an outer space, an intermediate face opposite the outer face, and a peripheral edge, 10 - an inner substrate having an inner face which faces an inner space, an intermediate surface opposite to the inner face, and a peripheral edge, - a glazing frame structure which is situated at the periphery of the intermediate face of said outer substrate and at the periphery of the intermediate face of said inner substrate and which holds the substrate exterior and interior substrate together so that the glazing separates said outer space from said interior space with a glazing cavity located between the outside substrate and a lamination comprising on the one hand at least one main glass-glass sheet and on the other hand a main plastic sheet, said main plastic sheet being in contact between the intermediate face. said outer substrate and the main glass sheet. The glazing according to the invention is remarkable in that it further comprises at least one connecting bridge which is separate from said glazing frame structure and provides a connection between a peripheral edge of said lamination and a surface located opposite -vis transversely on the other side of said glazing cavity. This connecting bridge is thus preferably located between a peripheral edge of the intermediate face of the inner substrate and a peripheral edge of the central intermediate face of the main glass sheet (the oriented one). to the glazing cavity) and / or a peripheral edge of the central intermediate face of the main plastic sheet (that which is oriented towards the glazing cavity). This connecting bridge 3034041 - 4 - thus performs a mechanical connection between a peripheral edge of the face which is located on the one hand of the glazing cavity and a peripheral edge of that (s) which is (are) located (s) on the other hand, the glazing cavity; this connecting bridge adheres to the two surfaces facing each other, transversely, on each side of said glazing cavity. Preferably, said lamination is not in direct contact with the glazing frame structure or is not bonded directly mechanically and / or chemically to the glazing structure. Thus, when the glazing is oriented vertically, the lamination comprising the main glass sheet and the main plastic sheet is disposed against the surface of the outer substrate which is oriented towards the glazing cavity; this lamination stops at the top, on the sides and at the bottom at a distance from the peripheral edge of the substrate which carries it, so that when this carrier substrate is broken, unintentionally, in the zone where it is not laminated, the connecting bridge retains the carrier substrate of the lamination and the lamination. In the case where the carrier substrate is intact, it remains possible to separate the carrier substrate from the lamination and the lamination of the remainder of the glazing to allow emergency evacuation, by breaking or cutting the bridge beforehand. Preferably, each substrate is made of glass which has undergone a chemical or thermal treatment intended to reinforce it. It is possible to realize the continuous or discontinuous link bridge. When the connecting bridge is continuous, it is then separated from said glazing frame structure along its entire length, in order to provide effective lamination (and outer substrate) retention. When the connecting bridge is discontinuous, it is present, separated from said glazing frame structure, over a length of between 20% and 95%, or even between 30 and 50%, of the periphery of said lamination. It is thus possible to reduce the weight of the glazing. It is possible, for example, to provide that the glazing comprises four connecting bridges, one along each edge (top, bottom, right, left) of the lamination and over a length, for example for each, of between one third and one half of the length of the edge of the lamination. Preferably, said connecting bridge is situated at a shortest distance of between 2.0 and 30.0 mm, and preferably at a shortest distance of between 5.0 and 20.0 mm, of said glazing frame structure. It is thus possible to provide a peripheral rupture zone of the outer substrate 5 which is sufficiently large, without reducing the clearness of view too much. This distance is preferably constant all along the periphery of the glazing frame structure (whether the connecting bridge is continuous or discontinuous). The connecting bridge may comprise a glue bead in particular based on polyurethane or silicone or MS polymer or polysulfide, so that the chemical bond on both sides of the glazing cavity is strong. The connecting bridge may comprise a metal section which is glued laterally to each side of the glazing cavity, with such a bead of glue or be partially embedded completely in such a bead of glue.
    [0003] The connecting bridge could comprise a cable, and in particular a wire rope, which is glued laterally to each side of the glazing cavity. Preferably, said connecting bridge is situated, seen from the inside and / or seen from the outside, behind a masking band, so that it is not presumed, in view of this connecting bridge, that the glazing would not be an emergency exit. It is preferable that each substrate is glass which has undergone a chemical or thermal treatment to strengthen it. In a first embodiment, the glazing is a single glazing. In a second embodiment, the glazing is openable. In this second mode, said outer substrate and said inner substrate each comprise, in an upper part, a hole opening on each face of the substrate and separated from the peripheral edge of the substrate, the holes of the substrates facing each other. one to the other, in order to make it possible to make an openable window, the glazing frame structure keeping the two substrates more evenly around the holes and, in a part of the glazing situated under said window, said lamination is not contact of said glazing frame structure. In this second embodiment, said glazing frame structure preferably comprises a horizontal crossmember located under said window, said crossmember not being in contact with two lateral uprights of the glazing frame structure. Said glazing cavity is preferably located all around said window (this glazing cavity is in one piece).
    [0004] The glazing according to the invention preferably has no outwardly projecting element beyond the outer face of the outer substrate. Each sheet of plastic material used for the glazing according to the invention has an ability to enhance the mechanical strength by adhering the glass sheet disposed thereon to the substrate or glass element disposed therebelow; in this glazing, at least one of these sheets of plastic material, or all these sheets of plastic material, may or may furthermore have a sound insulation capacity. Advantageously, the present invention thus makes it possible to produce a fixed multiple glazing of transport means which has high thermal insulation characteristics, high mechanical strength characteristics, while being able to serve as an emergency exit, with the certainty that even if this emergency exit is accidentally broken on the side of the lamination, it remains present in the glazing.
    [0005] The present invention makes it possible in particular, when the glazing comprises an opening window, that the space of the glazing unit which is situated under the opening window can be used as an emergency exit while preserving the integrity of the remainder of the glazing. that is to say, by allowing the window structure to remain in place so as not to impede the evacuation, below, by the emergency exit thus created. Advantageously, the present invention thus makes it possible to produce a fixed multiple glazing, possibly with an openable window, which has a smooth exterior view, with no mechanical element more outward than the outer face of the external substrate.
    [0006] The details and advantageous features of the invention emerge from the following nonlimiting examples, illustrated with the aid of the accompanying figures illustrating: in FIG. 1, a first embodiment of a glazing unit according to the invention without an opening window, seen from the interior space; - In Figure 2, the glazing of Figure 1 seen in section along AA of this figure, according to a first variant; 5 - in FIG. 3, the glazing unit of FIG. 1 seen in section along AA of this figure, according to a second variant; - In Figure 4, the glazing of Figure 1 seen in section along AA of this figure, according to a third variant; - In Figure 5, a second embodiment of a glazing according to the invention, with openable window, seen from the interior space; in Figure 6, the outer substrate of the glazing of Figure 5 seen from the glazing cavity and outwardly; in Figure 7, the inner substrate of the glazing of Figure 5 seen from the glazing cavity and inwardly; and 15 - in Figure 8, the glazing of Figure 5 seen in section BB of this figure, according to a first variant. In Figures 1 to 8 the proportions between the dimensions of the different elements are respected in order to facilitate their reading; the same references denote the same elements in all the figures. Figures 1 and 5 illustrate a side glazing 1 of a means of transport, according to the invention, as it can be seen by a passenger located inside this means of transport.
    [0007] This is in particular a side window of the train and FIG. 1 thus illustrates what a passenger of the train sees while looking on a left or right side with respect to a general direction of advance of the train. This glazing thus makes a vertical separation between an interior space I which is inside the train and an outside space E which is outside the train. This glazing 1 is fixed. In the first embodiment, that of FIG. 1, the glazing unit 1 is in one piece, with no window openable inside, whereas in the second embodiment, that of FIG. window 2 working.
    [0008] This glazing 1 comprises: - an outer substrate 10 which has two main faces: an outer face 11 which faces the outer space E and an intermediate face 12 which is opposite to the outer face; this substrate further includes a peripheral edge 13, - an inner substrate 20 which has two main faces: an inner face 21 which faces the inner space I and an intermediate face 22 which is opposite to the inner face ; this substrate further comprises a peripheral edge 23, 10 - and a glazing frame structure 3 which firmly holds together the outer substrate 10 and the inner substrate 20; however, a closed space is located between the two substrates: it is a glazing cavity 4. The outer substrate 10 and the inner substrate 20 are each in one piece.
    [0009] In the second embodiment only, which will be described in more detail below, the outer substrate 10 and the inner substrate 20 each comprise, in an upper portion (relative to the vertical), a hole 14, 24, each hole opening on each face of each substrate and is separated from the peripheral edge of the substrate, the holes of the substrates being opposite each other, in order to make it possible to make a window 2 openable. The glazing frame structure 3 further maintains the two substrates around the holes 14, 24. The glazing frame structure 3 thus makes it possible to keep the two substrates 10, 20 at a distance from one another, with a distance constant between the two substrates 10, 20. The glazing 1 is a multiple glazing in the sense that it comprises several substrates 10, 20 and the glazing cavity 4 which is located between the two substrates, this cavity being filled with air or gas, preferably neutral as argon; this cavity participates in the thermal insulation conferred by the glazing 1. This glazing 1 is a fixed glazing in the sense that the glazing frame structure 3 is intended to be fixed to the structure of the transport means (here the train) , without possibility of moving relative to this structure. As can be seen more particularly in FIG. 2, the glazing frame structure 3 comprises a peripheral spacer 30 (or "spacer") which is located all around the periphery of the two substrates 10, 20, that is, that is to say that it follows the peripheral edge 13, 23 of these two substrates, making a continuity between these two songs and extending towards the center of the glazing. This spacer is preferably in one piece. This spacer is here positioned against the intermediate faces 12, 22 of the substrates, around these intermediate faces 12, 22, without being in contact with the peripheral edges 13, 23 of the substrates. It is glued laterally to the intermediate faces 12, 22 of the substrates. The spacer may be for example plastic and / or metal and / or metal alloy; it makes it possible to maintain the two substrates 10, 20 at a constant distance from one another and to create the glazing cavity 4.
    [0010] The spacer may comprise a metal profile, such as for example an aluminum profile, and a double adhesive bead, for bonding this profile to the periphery of the intermediate faces 12, 22; it may further comprise a sealant and / or a glazing joint which holds the glazing by pressing against a stop of the bay.
    [0011] With regard to the height of the spacer (when viewed vertically), the particular lamination results in the main glass sheet 15 and the main plastic sheet 16 being set back t at least 2 mm, and preferably at least 5 mm, with respect to said glazing frame structure 3, i.e. with respect to the peripheral strut 30 at the top of this lamination, on the lateral sides and at the bottom of this leaflet. The glazing frame structure 3 furthermore comprises horizontal high 32 and low 32 'uprights, as well as left 33 and right side uprights 33' (seen from the inside, as in FIG. 1). These amounts are preferably of metal or metal alloy. The glazing frame structure 3 further comprises a peripheral adhesive bead 34 which makes it possible to bond the peripheral edges 13, 23 of the substrates and the peripheral spacer 30 with the uprights 32, 32 ', 33, 33'. This adhesive bead may for example be based on polyurethane or silicone or MS polymer or polysulfide. The posts 32, 32 ', 33 and 33' are optional because it is possible for the glazing to be stuck in the rack without using studs or using only side jambs or horizontal studs. It has been verified that an adequate mechanical strength is obtained on the basis of the example of FIGS. 1 to 4, when: the two substrates 10, 20 are each made of glass which has undergone a treatment intended to reinforce it, such as In a heat treatment and in particular a quenching heat treatment and are each of a thickness of 3 to 8 mm, for example 4 mm, the main glass sheet 15 is made of glass which has not undergone any treatment intended for the treatment. 2 mm thick, the main plastic sheet 16 is made of PVB and has a thickness of 0.76 mm. Optionally, the main glass sheet 15 may be made of glass which has undergone a treatment intended to reinforce it, such as a heat treatment and in particular a quenching heat treatment. It has been verified that adequate thermal insulation is obtained on the basis of the example of FIGS. 1 to 4, when said glazing cavity 4 is in one piece, filled with argon and provided with on the one hand a uniform thickness. The distance between the outer face 11 and the inner face 21 is thus constant and is here 25.76 mm.
    [0012] In the first embodiment of the invention, the intermediate face 12 of the outer substrate 10, which faces the glazing cavity 4, comprises a lamination 5 comprising: - on the one hand a main glass sheet 15 - and on the other hand a main plastic sheet 16, 30 - with this main plastic sheet 16 which is situated between the intermediate face 12 and the main glass sheet 15, - this main plastic sheet 16 which is in contact both with the intermediate face 12 and with the main glass sheet 15, without the main glass sheet 15 and without the main plastic sheet 16 in contact with said glazing frame structure 3. The lamination thus comprises: 5 - the main glass sheet 15 which has two main faces: an outer main face 51 which is oriented towards the outer substrate 10 and an intermediate face a central jet 52 which is opposite, facing the glazing cavity 4; this main glass sheet 15 further comprises a peripheral edge, and 10 - the main plastic sheet 16 which has two main faces: an outer main 61 which is oriented towards the outer substrate 10 and a central intermediate face 62 which is the opposite, facing the glazing cavity 4; this sheet of main plastic material 16 also has a peripheral edge.
    [0013] Thus, the glazing 1 comprises at least one external substrate which is laminated, but this lamination is particular because the plastic sheet and the glass sheet which are added in this order on the intermediate face of the substrate have a periphery constricted relative to at the periphery of the substrate so as not to be in contact with either one or the other with the glazing frame structure 3. The edges of the sheets constituting the lamination are therefore not in contact with the structure of the This characteristic is seen more particularly in FIG. 1 in which it is illustrated that the lamination 5 carried out by the main glass sheet 15 which is glued to the intermediate surface 12 by the main plastic sheet 16 stops. at the top, bottom, left and right at a distance s from the peripheral edge 13; this distance s is at least 5 mm, and preferably at least 7 mm; it can be for example 6 mm, or 8 mm.
    [0014] This characteristic is important for conferring on the glazing its quality of security and evacuation glazing: when the glazing 1 must be broken to allow evacuation, the inner substrate 20 is first broken, for example with a hammer; then, repeated shocks against the main glass sheet will break this sheet and then break the outer substrate 10 where the lamination 5 (main glass sheet 15 + main plastic sheet 16) is absent , that is to say at the place marked by the zones of rupture Z, which are located all around the lamination, on the distance s.
    [0015] If the plastic sheet and the glass sheet which are added on the intermediate face of the outer substrate went to the peripheral edge 13 of the substrate, then these sheets would be in contact with the glazing frame structure 3 and the stress required to break the glazing in an emergency would be too great to permit evacuation under the required conditions. However, it is possible that the outer substrate 10 breaks, and in particular breaks in a rupture zone Z where there is no lamination, under the effect of an impact coming from the outside, such as by example a pebble from the ballast and projected by the breath of another train.
    [0016] Thus, to secure the glazing and prevent the outer substrate 10 (and the laminate 5) from falling, at least one connecting bridge 6 is provided. This connecting bridge 6 may be located: - between the intermediate face 22 of the inner substrate 20 and the central intermediate face 52 of the main glass sheet 15, as illustrated in FIG. 2, or - between the intermediate face 22 of the inner substrate 20 and the central intermediate face 62 of the main plastic sheet 16, as illustrated in FIG. 3, or - between, on the one hand, the intermediate face 22 of the inner substrate 20 and on the other hand at the same time at the intermediate face. central 52 of the main glass sheet 15 and the central intermediate face 62 of the main plastic sheet 16, as shown in FIG. 4. When the glazing 1 is viewed from the front, as in FIG. 1, it is possible to consider that the glazing has a center which is in the plane 30 of the sheet. By following this consideration, the glazing frame structure 3 is more centrifugal than the connecting bridge 6. In this figure, the connecting bridge 6 is continuous and it is separated from the glazing frame structure 3 over its entire length; it is separated by a secondary glazing cavity, similar to the main glazing cavity 4. Along its periphery, the connecting bridge is not in direct contact with the glazing frame structure and thus is not in direct contact with the peripheral spacer 30. It is possible to realize the connecting bridge 6 discontinuous; it can then be present over a length of between 20% and 95% of the periphery of said lamination 5. However, in this case, the connecting bridge 6 is also separated from the glazing frame structure 3. It is not necessary to provide a large volume between the connecting bridge 6 and the glazing frame structure 3; it is sufficient to provide that they are not bonded to each other, either mechanically or chemically (eg by glue), so that the outer substrate 10 can be easily separated from the rest of the glazing in order to act as an escape route. The connecting bridge 6 is located at a shortest distance v between 2.0 and 30.0 mm, and preferably at a distance v at the shortest between 5.0 and 20.0 mm, from said structure 3 A constant value v of 5.0 mm all around the connecting bridge gives good results: the zone Z is sufficiently large so that the substrate 10 can be separated relatively easily from the rest of the glazing, without diminishing too much. the clear view through the glazing.
    [0017] The connecting bridge 6 is here a bead of polyurethane-based glue; it could also be a bead of glue based on silicone or MS polymer or polysulfide. The connecting bridge 6 can thus be in the same material as the peripheral adhesive bead 34. The connecting bridge 6 is located, seen from the inside I behind a masking band 9 so as not to be visible to the users. means of transport. In the second embodiment, illustrated in FIGS. 5 to 8, the window 2, and it alone, is movable with respect to the glazing frame structure 3. The window 2 is a window internal to the glazing 1; it is openable in the sense that it can be opened and closed relative to the glazing frame structure 3, which is fixed. Of course, means are provided to guide these opening and closing movements, as well as for the 3034041 - 14 - limit. For security reasons, the window 2 is openable to the interior space and not to the outside space. In this second embodiment, the intermediate face 12 of the outer substrate 10, the one facing the glazing cavity 4, comprises in a part of the glazing which is located under the said window: on the one hand a sheet of glass main 15 - and on the other hand a main plastic sheet 16, - with this main plastic sheet 16 which is located between the intermediate face 12 and the main glass sheet 15, 10 - this main plastic sheet 16 which is in contact with both the intermediate face 12 and the main glass sheet 15, - without the main glass sheet 15 and the main plastic sheet 16 being in contact with said glazing frame structure 3.
    [0018] Thus, in the second variant, the glazing 1 comprises at least one of its substrates which is laminated, in this case the outer substrate 10, but this lamination is particular because the plastic sheet and then the glass sheet which are added in this order on the intermediate face of the outer substrate have a periphery constricted relative to the periphery of the outer substrate under the window 2 so as not to be in contact, either with the frame structure This characteristic is seen more particularly in FIG. 6 where it is illustrated that the lamination made by the main glass sheet 15 which is bonded to the intermediate surface 12 by the main plastics material 16 stops at the top at a distance of distance s from the lower edge of the hole 14 and also stops at a distance, which is preferably the same, the peripheral edge 13; this distance s is at least 5 mm, and preferably at least 7 mm; it can be for example 6 mm, or 8 mm. This characteristic is important for conferring on the glazing its quality of safety glazing while preserving the structure of the window; if the plastic sheet and the glass sheet which are added on the intermediate face of the substrate went to the peripheral edge 13 of the substrate and to the lower edge of the hole 14, then these sheets would be in contact with the frame structure glazing 3 and the effort 3034041 - 15 - required to break the glazing under the window in case of emergency could damage the window frame structure. However, if this structure is damaged, it may hinder evacuation; it is an object of the invention to avoid this.
    [0019] In the embodiment of the second variant which is detailed here, only the intermediate face 12 of the outer substrate 10 has in a part of the glazing which is located under said window the main plastic sheet 16, then on this sheet of main plastics material the main glass sheet 15 (i.e. a laminating), but it could be envisaged that the intermediate face 22 of the inner substrate 20 also has a lamination in a part of the glazing which is located under said window . As seen more particularly in FIG. 8, the glazing frame structure 3 comprises two spacers: a peripheral spacer 30 (or "spacer") which is located all around the periphery of the two substrates 10, 20, it is that is to say that it follows the peripheral edge 13, 23 of these two substrates and - an internal spacer 31 (or "spacer") which is located all around the periphery of the two holes 14, 24.
    [0020] Each of these two spacers is preferably in one piece. They are not in contact with each other. Each of these two spacers is here positioned against the intermediate faces 12, 22 of the substrates, without being in contact with the peripheral edges 13, 23 of the substrates. They are glued laterally to the intermediate faces 12, 22 of the substrates. The spacers may be for example plastic and / or metal and / or metal alloy; they make it possible to maintain the two substrates 10, 20 at a constant distance from one another and to create the glazing cavity 4.
    [0021] With regard to the height of the spacers (when viewed vertically), the distance evoked above results in the fact that the main glass sheet 15 and the main plastic sheet 16 are set back t from minus 2 mm, and preferably at least 5 mm, with respect to said glazing frame structure 3, i.e. 3034041 relative to the inner spacer 31 at the top of this lamination and relative to the peripheral spacer 30 on the lateral sides and at the bottom of this lamination. The glazing frame structure 3 also comprises high horizontal 32 and low 32 'uprights, as well as left side posts 33 and 33 right 33' (seen from the inside, as in Figure 5). These amounts are preferably metal or metal alloy. The glazing frame structure 3 further comprises a peripheral adhesive bead 34 which makes it possible to bond the peripheral edges 13, 23 of the substrates and the peripheral spacer 30 with the uprights 32, 32 ', 33, 33'.
    [0022] This bead of glue may for example be based on polyurethane or silicone or MS polymer or polysulfide. Amounts 32; 32 ', 33 and 33' are optional because the glazing may be stuck in the rack without using studs or using only side jambs or horizontal studs.
    [0023] As can be seen in FIGS. 6 and 8, the intermediate face 12 of the outer substrate comprises in a part of the glazing situated above said window 2 (and more precisely in this figure above the hole 14 which accommodates the window 2), on the one hand a secondary glass sheet 17 and on the other hand a secondary plastic sheet 18 which is interposed, in contact, between the intermediate face 12 and the secondary glass sheet 17. The secondary plastic sheet 18 and the secondary glass sheet 17 are also located on each lateral side of said window (and more precisely in this figure on each lateral side of the hole 14 which accommodates the window 2). Thus, the lamination by the secondary plastics sheet 18 and the secondary glass sheet 17 surrounds the hole 14 above and on its left and right sides, having an inverted U-shape; this lamination does not extend below the hole 14 because it is another lamination which is present below this hole: the lamination with the main plastic sheet 16 and the main glass sheet 15. For a good performance mechanically of the lamination above the window and on these sides, the secondary glass sheet 17 and the secondary plastic sheet 18 are preferably in contact with said glazing frame structure 3 and more particularly here, near the peripheral edge 13 in contact with the peripheral spacer 30 and near the hole 14 in contact with the inner spacer 31. The secondary glass sheet 17 preferably has the same thickness as the main glass sheet 15 and the secondary plastic sheet 18 preferably has the same thickness as the main plastic sheet 16; however, these sheets of glass and its plastic sheets do not overlap. As visible in FIGS. 7 and 8, the intermediate face 22 of the inner substrate 10 comprises in a part of the glazing situated above said window 2 (and more precisely in this figure above the hole 24 which accommodates the window 2), on the one hand a secondary glass sheet 17 'and on the other hand a secondary plastic sheet 18' which is interposed, in contact, between the intermediate face 22 and the secondary glass sheet 17 '. The secondary plastic sheet 18 'and the secondary glass sheet 17' are also located on each lateral side of said window (and more precisely in this figure on each lateral side of the hole 24 which accommodates the window 2).
    [0024] For good mechanical strength of this lamination, the secondary glass sheet 17 'and the secondary plastic sheet 18' are preferably in contact with said glazing frame structure 3 and more particularly here, near the edge 23 in contact with the peripheral spacer 30 and near the hole 24 in contact with the inner spacer 31. It has been verified that adequate mechanical strength is obtained on the basis of the example of Figures 5 to 8 when: the two substrates 10, 20 are each made of glass which has undergone a treatment intended to reinforce it, such as a heat treatment and in particular a quenching heat treatment and are each of a thickness of 3 to 8; mm, for example 4 mm - the main glass sheet 15 and the two secondary glass sheets 17, 17 'are all made of glass which has not undergone any treatment intended to reinforce it and are each of a thickness of 2 mm 3034041 -18- - the main plastic sheet 16 and the two secondary plastic sheets 18, 18 'are all three of PVB and are each 0.76 mm thick. Optionally, the main glass sheet 15 and the two secondary glass 17, 17 'may be made of glass which has undergone a treatment intended to reinforce them, such as a heat treatment and in particular a quenching heat treatment. It has been verified that adequate thermal insulation is obtained on the basis of the example of FIGS. 5 to 8, when said glazing cavity 4 is located all around said window 2, in one piece, that it is filled with argon and has on the one hand a uniform thickness in its part under the window 2 and on the other hand a uniform thickness in its part on each side and above the window 2. The distance between the outer face 11 and the inner face 21 is thus constant and is here 25.76 mm. As can be seen in FIG. 8, the window 2 comprises an outer glass element 40, an inner glass element 80 and a window frame structure 35 which holds the outer glass element 40 with the inner glass element 80 by producing a window cavity. 8 which is thus located between the outer glass element 40 and the inner glass element 80: the outer glass element 40 comprises two main faces: an outer face 41 which faces the outer space E and an intermediate face 42 which is opposite to the outer face; the outer glass element 40 further comprises a peripheral edge 43, 25 - the inner glass element 80 has two main faces: an inner face 81 which faces the inner space I and an intermediate face 82 which is at the opposite of the inner face; the inner glass element 80 furthermore has a peripheral edge 83. As seen more particularly in FIG. 8, the window frame structure 35 comprises a peripheral window spacer 36 (or "spacer") which is located all around the periphery of the two glass elements 40, 80. This peripheral window spacer 36 is preferably in one piece and is here positioned against the intermediate faces 42, 82 of the glass elements, without being in contact with the songs peripherals 43, 83 of these glass elements. This spacers may be for example plastic and / or metal and / or metal alloy and keeps the two glass elements 40, 80 at a constant distance from one another and create the window cavity 8. The window frame structure 35 further includes high and low horizontal uprights, as well as left and right side uprights. These amounts are preferably metal or metal alloy.
    [0025] The window frame structure 35 further includes a peripheral glue bead 34 'for adhering the peripheral edges 43, 83 of the glass elements and the peripheral window spacer 36 to the posts. This glue bead 34 'is preferably in the same material as the peripheral glue bead 34.
    [0026] The face 42 of the outer glass element which faces the window cavity 8 comprises: - on the one hand a window glass sheet 45 - and on the other hand a window plastic sheet 46, - with this window plastic sheet 46 which is located between the intermediate face 42 and the window glass sheet 45, this window plastic sheet 46 which is in contact with both the intermediate face 42 and the window glass sheet 45, with the window glass sheet 45 and the window plastic sheet 46 in contact with the window frame structure 35 (and more specifically here the peripheral glue strip 34 '). The two glass elements 40, 80 are each made of glass which has undergone a treatment intended to reinforce it, such as a heat treatment and in particular a quenching heat treatment and are each of identical thickness to the substrates 10, 20, respectively.
    [0027] The window glass sheet 45 has the same thickness as the main glass sheet 15 and the window plastic sheet 46 has the same thickness as the main plastic sheet 16. The distance d between the glass sheet 45 has the same thickness as the main glass sheet 16. outer face 41 and the inner face 81 is thus constant and is here 25.76 mm; it is identical to the distance between the outer face 11 and the inner face 21. The window 2 is movable relative to the glazing frame structure 3 5 in a rotational movement illustrated by the double arrow R in FIG. inside; this movement is limited to an opening angle of approximately 45 °. To enable this opening, the glazing frame structure 3 comprises a horizontal crossmember 38 located beneath said window 2 which allows the horizontal lowermost amount of window frame to pivot on itself along a horizontal axis and with respect to the crossmember. 38 horizontal. Two handles 29 are provided on the upper upright of the window frame structure 35 to facilitate the gripping of the window 2 by the passengers who wishes to open or close it.
    [0028] The cross member 38 is also preferably made of metal or metal alloy and is bonded to the inner face 21 of the inner substrate 20 by means of the bead of adhesive which surrounds the holes 14, 24. This cross member 38 is not in contact with two lateral uprights 33, 33 'of the glazing frame structure 3.
    [0029] However, to hide the absence of lamination to the left and right of the cross member 38 over a few millimeters, side covers 39, 39 'are glued on the inner face 21, as shown in Figure 5. A decorative pattern applied for example screen printing on the intermediate faces 12 and 22 can also ensure this aesthetic function.
    [0030] As can be seen in FIG. 8, the glazing unit 1 according to the invention has no outwardly protruding element, beyond the outer face 11 of the outer substrate 10. Thus, to secure the glazing and prevent the outer substrate 10 ( and the lamination 5) to fall in case of accidental breaking of this substrate, at least one connecting bridge 6 is provided. This connecting bridge 6 may be located between the intermediate face 22 of the inner substrate 20 and the central intermediate face 52 of the main glass sheet 15, as illustrated in FIG. 8. This connecting bridge 6 could also be located: 3034041 - 21 - - between the intermediate face 22 of the inner substrate 20 and the central intermediate face 62 of the main plastic sheet 16 (not shown), or between the intermediate face 22 of the inner substrate 20 5 and on the other hand both at the central intermediate face 52 of the main glass sheet 15 and at the central intermediate face 62 of the main plastic sheet 16 (not shown). The present invention is described in the foregoing by way of example.
    [0031] It is understood that one skilled in the art is able to realize different variants of the invention without departing from the scope of the patent as defined by the claims. In particular, it is included in the present invention that the inner substrate 20 may itself be laminated, with: - on the one hand an accessory glass sheet - and on the other hand an accessory plastic sheet, - with this accessory plastic sheet which is located between the intermediate face 22 of the inner substrate 20 and the accessory glass sheet.
    [0032] In this case, of course, it should be understood that the term "a peripheral edge of the intermediate face 22 of the inner substrate 20" means a peripheral edge of the intermediate face which may be that of the accessory glass sheet and / or that of the accessory plastic sheet, and which is in contact with the glazing cavity 4.
    [0033] On the other hand, the shortest distance v between the connecting bridge 6 and the adjacent glazing frame structure 3 is shown in the diagrams to be larger than the distance t between the lamination and the glazing frame structure 3. but it can be identical, or even be less than the distance t. The important thing is that this connecting bridge 6 is separated from the adjacent glazing frame structure 3.
