SYSTEM FOR ATTACHING SIDE GLAZING OF A TRANSPORT VEHICLE WITH A LOCK

Description

[0001] The invention relates to the fixing of a side glazing of a means of transport, and in particular of a train glazing, to a peripheral bay, generally metallic, said glazing being a multiple, fixed glazing. This type of glazing is usually fixed to the bay of the train in a vertical position.

[0002] The invention relates more particularly to the fixing of a side glazing having an outer face which faces an exterior space and an inner face which faces an interior space, said outer face of the glazing being in continuity of appearance with an outer face or an outer flank of said opening over its entire periphery. Continuity of appearance does not mean that there is contact between the outer face of the glazing and the outer face of the opening because it is known that such contact must be avoided, especially when the opening is metallic; continuity of appearance implies that, seen in vertical cross-section, the outer face of the opening is in continuity with the outer face of the glazing with a non-zero distance between them.

[0003] Such multiple glazing of means of transport usually includes: an outer pane having an outer face facing an outer space, an intermediate face opposite the outer face, and a peripheral edge, an inner pane having an inner face facing an inner space, an intermediate face opposite the inner face, and a peripheral edge, and an internal structure which is located on the inner periphery of said outer pane and on the inner periphery of said inner pane while being more towards the center than the peripheral edge respectively of said outer pane and said inner pane, and which holds these two panes together such that the glazing creates a separation between said outer space and said inner space with a glazing cavity located between said panes.

[0004] It is known, in particular from international patent application No. WO 2019 / 228850, to provide that a multiple glazing unit for a means of transport also comprises a glazing frame structure with: a part of this structure which is an internal structure and which is located on the internal periphery of said outer pane and on the internal periphery of said inner pane, being further towards the center than the peripheral edge respectively of said outer pane and said inner pane, and which holds these two panes together in such a way that the glazing creates a separation between said outer space and said inner space with a glazing cavity located between said panes, and a part of this structure which is an external structure and which extends on the external periphery of said outer pane and / or on the external periphery of said inner pane, being further than the peripheral edge respectively of said outer pane and / or said inner pane starting from the center of the pane.

[0005] Such an external glazing structure is then mechanically and / or chemically fixed to the bay that the glazing is to close.

[0006] Thus, in this document, the internal structure integrates the spacer 71 and the bead of mastic 76 which are both located on the internal periphery of the glazing cavity 8 and the external structure integrates the bead of glue 70 and the frame 72.

[0007] Another solution for fixing glazing for a means of transport is visible in international patent application No. WO 2016 / 151256: the glazing is simply glued using a peripheral bead of glue, visible in black in the figures of this document.

[0008] The prior art also includes documents US 2,256,548, DE 4009348 and JP-H07-6023.

[0009] The prior art fixing solutions by gluing or by mechanical fixing by two-part frame or even by clamp are satisfactory to the extent that the glazing is correctly fixed but require access to the interior of the means of transport during fixing; however, this access can be difficult. This difficult access also greatly complicates the replacement of such glazing during the life of the means of transport.

[0010] Furthermore, at the end of the means of transport's life, these solutions require complex dismantling, recycling and sorting operations.

[0011] The aim of the invention is to make it possible to produce multiple, fixed glazing, fixed to a bay in the body of a means of transport from the outside, without needing to access the inside for replacement.

[0012] Another aim is to enable such glazing to be produced without providing an external rigid frame and in particular without a metal or metal alloy frame external to the glazing itself. Indeed, it can be difficult to manage the durability over time, in particular the corrosion resistance, of a metal or metal alloy frame.

[0013] In addition, the glazing is less expensive and lighter.

[0014] Furthermore, this frame generally reduces the clear glazing, so removing it can increase this clear glazing, for an identical bay size.

[0015] Finally, removing the external structural frame can make it possible to create a shallower bay, thus increasing the space available inside the means of transport.

[0016] The invention is thus based on providing at least one lock, and preferably several locks, and in particular several locks along each side of the glazing, to mechanically and effectively retain a multiple glazing by the periphery of the glazing cavity while allowing it to be changed quickly, only from the outside.

[0017] Thus, at least one socket, and preferably a multitude of sockets, is (or are) made directly in the sealing of the multiple glazing and only in this sealing, all around the bay, without any other mechanical fixing.

[0018] Surprisingly, it was found that it was possible to fix glazing in this way in a peripheral bay, even for glazing intended to be subjected to numerous vibrations due to its use as glazing for a means of transport, and in particular for a train.

[0019] The subject of the invention, in its broadest sense, is a system for fixing a side glazing of a means of transport, in particular a train glazing, to a peripheral bay according to claim 1. In this fixing system, said glazing is a multiple, fixed glazing, having an outer face which faces an exterior space and an inner face which faces an interior space, said outer face of the glazing being in continuity in appearance with an outer face of said bay over its entire periphery and said glazing comprising: an outer pane having an outer face which faces an outer space, said outer pane preferably being laminated and then comprising at least one outer glass sheet, one inner glass sheet, as well as a plastic sheet located between said outer glass sheet and said inner glass sheet, each sheet of said outer pane having a peripheral edge, an inner pane, which may optionally be laminated, having an inner face which faces an inner space, an intermediate face opposite the inner face, as well as a peripheral edge, an internal structure which is located on the inner periphery of said outer pane and on the inner periphery of said inner pane being further towards the center than the peripheral edge respectively of said outer pane and said inner pane,and which holds these two panes together in such a way that the glazing creates a separation between said exterior space and said interior space with a glazing cavity located between said panes.

[0020] The glazing according to the invention is remarkable in that said internal structure comprises a hanging cavity having a centripetal bottom and a centrifugal opening, in that said bay comprises an internal flank having a fixing hole which is located more centrifugal than said edge of said internal pane and having an axis parallel to said edge of said internal pane and in that a lock is fixed to said internal flank by a fixing means passing through said fixing hole, said lock having a lateral wing extending inside said hanging cavity and opposite an edge of said intermediate face of the internal pane by 90° rotation of said lateral wing.

[0021] Said 90° rotation can be the rotation of said lateral wing alone on itself or the rotation of the complete lock on itself.

[0022] To keep the fastening system compact enough, each lock preferably has a single side wing.

[0023] The 90° rotation of the lock on itself is preferably achieved by rotation around the axis of the fixing hole. The lock is thus introduced into an applique space, which is located between the glazing and an adjacent bay crosspiece, with the side wing oriented along this space, then the lock is turned on itself to make the side wing penetrate into said hanging cavity.

[0024] The lock thus works like a latch. It is this rotation that allows the glazing to be fixed or attached to the bay in one direction and detached from the bay in the opposite direction.

[0025] Said hanging cavity is preferably formed by a groove located at the location of the lock or by an elongated rail; each horizontal or vertical edge of the glazing then preferably comprises a single rail; preferably, there is then no rail in the corners of the glazing.

[0026] Said attachment cavity preferably has a depth, i.e. a distance between its centripetal bottom and its centrifugal opening, of between 2.0 and 15.0 mm, preferably between 3.0 and 10.0 mm. This distance is both large for good fixing of the glazing, i.e. good maintenance of the lateral wing in the attachment cavity and small so as not to restrict the clear glazing too much.

[0027] In order to have a more compact system, it is possible that said rotation of the lock on itself is eccentric so that said lateral wing moves away from said axis of the fixing hole during the movement of the penetration of said lateral wing into said hooking cavity.

[0028] Preferably, said internal structure does not protrude in the centrifugal direction further than the edge of said outer pane or the edge of said inner pane and more preferably said internal structure does not protrude in the centrifugal direction further than the edge of said outer pane or the edge of said inner pane.

[0029] To facilitate the manufacture of the glazing, the said inner glass sheet may have dimensions identical (length, height) to the dimensions of the inner pane.

[0030] The said inner pane can itself be laminated but then, to facilitate manufacturing, the constituent sheets of the pane preferably have identical dimensions (length, height).

[0031] In a variant, the edge of said outer pane or the edge of said outer glass sheet is located in centrifugal projection of the edge of said inner pane along at least part of the length of the edge of said outer pane or of said outer glass sheet and preferably along the entire length of the edge (i.e. along the entire periphery of the edge) of said outer pane or of said outer glass sheet.

[0032] The said overhang is between 5.0 and 30.0 mm, and preferably between 8.0 and 20.0 mm. This contributes to the compactness of the fixing.

[0033] The concept of overhang is used in reference to the center of the glass sheet, the window, or the glazing; it designates a centrifugal position, further from this center than what is used for reference.

[0034] In another, independent variant, said edge of said plastic sheet and / or said edge of said inner glass sheet is (or are) located centripetally set back from the edge of said inner pane along at least part of the length of the edge of said plastic sheet and / or said inner glass sheet and preferably along the entire length of the edge (i.e. along the entire periphery of the edge) of said plastic sheet and / or said inner glass sheet.

[0035] Said withdrawal is preferably between 1.0 and 10.0 mm, and more preferably between 2.0 and 8.0 mm. This contributes to the compactness of the fixing.

[0036] The concept of withdrawal is used in reference to the center of the glass sheet, the window, or the glazing; it designates a centripetal positioning, closer to this center, than what is used for reference.

[0037] The manufacture of laminated glass (here the outer glass) whose constituent sheets do not all have identical dimensions (length, height) is more complicated, but the advantages provided by said overhang and / or said recess are very significant: it / they allow / they improve the appearance of the glazing and the compactness of the fixing.

[0038] Said glazing preferably comprises a spacer which is located between said inner glass sheet and said inner pane, set back from the edges of said inner glass sheet and said inner pane while being spaced apart, seen in cross-section, by a distance further peripherally than the transverse continuity of the edge of said outer glass sheet, said distance being between 2.0 and 30.0 mm, and preferably between 5.0 and 20.0 mm, or even between 6.0 and 15.0 mm.

[0039] It is possible that a sheet of glass, several sheets of glass, or even each sheet of glass has undergone a chemical or thermal treatment intended to strengthen it.

[0040] At least one sheet of plastic material in the glazing, or even all the sheets of plastic material if there are several, may also have a sound insulation capacity.

[0041] In a particular embodiment, the edge of said outer pane or the edge of said inner glass sheet comprises a centrifugal lip made of plastic. This lip helps to protect the lock located further inside.

[0042] The fact that said outer face of the glazing is in continuity in appearance with said outer face of said bay over its entire periphery implies a non-zero distance between them.

[0043] This distance between said outer face of the glazing and said outer face of said bay is preferably between 5.0 and 25.0 mm and more preferably between 8.0 and 15.0 mm, which is very small. The body of the lock preferably has a diameter or height identical to this distance, so that it can be introduced into the application space. The side wing of the lock preferably has a width identical to this distance so that it can be introduced into the application space.

[0044] Along this distance, preferably, an external seal is present in contact between on the one hand an edge of said external face of the bay and on the other hand the edge of said external pane or the edge of said external glass sheet when the external pane is laminated, said external seal preferably having a height of between 5.0 and 30.0 mm, and preferably between 8.0 and 20.0 mm. This short distance makes it possible to obtain a pleasant visual appearance and contributes to obtaining a high glazing clarity.

[0045] When a centrifugal lip is present, it can provide a bottom for the outer seal to prevent it from reaching the latch.

[0046] The glazing according to the invention preferably does not include any element projecting outwards, beyond the outer face of said glazing, which is also the outer face of said outer window, in order to reduce friction in the air for the means of transport. The glazing can then be positioned in continuity of external appearance with the bodywork bay, the outer face of the glazing being at a distance from the outer face of the bay.

[0047] When an external seal is located between said external face of the glazing and said external face of the opening, then the glazing can be considered flush with the bodywork opening.

[0048] An internal seal is also preferably present in contact between, on the one hand, said internal side of the bay and, on the other hand, said internal face of the internal window.

[0049] Advantageously, the present invention thus makes it possible to produce fixed multiple glazing, possibly with an openable window, the fixing of which is accessible from the outside and which presents a smooth external view, without any mechanical element further outside than the external face of the external pane.

[0050] Thanks to the fixing according to the invention, the glazing clearness is relatively large; it is, for the most part, defined by the position of the spacer.

[0051] The present invention also relates to the use of at least one lock (and preferably several locks, in particular several locks along each edge) with a lateral wing each penetrating into said attachment cavity by rotation of the lock through 90° on itself for fixing a side glazing of a means of transport, in particular a train glazing, to a peripheral bay.

[0052] The glazing fastening system according to the invention is a system for fastening side glazing of a means of transport. It is a reliable system, although the glazing is intended to undergo numerous vibrations due to its use as side glazing of a means of transport.

[0053] The details and advantageous characteristics of the invention emerge from the following non-limiting examples, illustrated using the attached figures for which: there figure 1 illustrates a perspective diagram of the exterior of a train body bay comprising multiple glazing which is fixed to the bay using a fixing system according to the invention, the system being illustrated without an external seal; figure 2 illustrates a vertical cross-sectional diagram at the bottom of a glazing fixed to a bay according to a first embodiment according to the invention; the figure 3 illustrates the diagram of the glazing of the figure 2 , alone; the figure 4 illustrates a diagram in vertical cross-section at the top of a glazing fixed to a bay according to a second fixing method according to the invention; the figure 5 and the figure 6 respectively illustrate a side and front face diagram of a lock according to the invention with centered rotation; the figure 7 and the figure 8 respectively illustrate a side and front face diagram of a lock according to the invention with eccentric rotation; the figure 9 illustrates a front diagram, by transparency, from the outside, of a high lock in the open position according to a third embodiment according to the invention; the figure 10 illustrates a front diagram, by transparency, from the outside, of the lock of the figure 9 in closed position; and the figure 11 illustrates a perspective diagram, by transparency, of the exterior, of the lock of the figure 9 in closed position.

[0054] In these diagrams, the proportions between the dimensions of the different elements are not respected in order to facilitate their reading.

[0055] There figure 1 illustrates a left side glazing 1 according to the invention of a means of transport, this glazing being positioned vertically and fixed to a bay 9 of the bodywork of this means of transport.

[0056] This is particularly the case for train side glazing.

[0057] This glazing thus creates a vertical separation between an interior space l which is inside the train and an exterior space E which is outside the train. figure 1 is a schematic view of the exterior.

[0058] The notions of "exterior" and "interior" are therefore considered in this document respectively in relation to this exterior space E (or oriented towards this exterior space) and this interior space I (or oriented towards this interior space).

[0059] As this is a side glazing, it extends essentially along the axis generally called the “X axis” of the means of transport, which is the central longitudinal axis of advance of the means of transport equipped with the glazing according to the invention as side glazing (here on the left side) and which corresponds to the X axis figure 1 The Y axis is the vertical axis and the Z axis is the transverse axis.

[0060] In the context of this document, the notion of "centripetal" and that of "centrifugal" is to be considered in the plane of the sheet in figure 1 , or in a general plane of the glazing when it is considered flat, expressed in relation to the center of the glazing, according to the X and Y axes; the centripetal direction is in the direction of this center while the centrifugal direction moves away from this center.

[0061] This glazing 1 is fixed. It is a single piece, without an openable window inside as is known for example from international patent application No. WO 2016 / 042270; however, although this is not described in detail here, the invention could be applied to such glazing with an openable window.

[0062] This glazing 1 has an exterior face 101 which faces the exterior space E and an interior face 102 which faces the interior space I.

[0063] This glazing 1 includes: an outer pane 2 having an outer face 21 which faces the outer space E, an intermediate face 22 opposite the inner face, as well as a peripheral edge, an inner pane 6 having an inner face 62 which faces the inner space I, an intermediate face 61 opposite the inner face, as well as a peripheral edge 60, and an internal structure 7 and which holds these two panes together in such a way that the glazing separates the outer space and the inner space by creating a glazing cavity 8 which is located between the panes 2, 6.

[0064] The internal structure 7 is called “internal” because it is located on the internal periphery of the outer pane 2 and on the internal periphery of the inner pane 6, being more towards the center (more centripetal) than the peripheral edge 20, 60 respectively of the outer pane 2 and of the inner pane 6; that is to say that the internal structure 7 does not protrude in a centrifugal direction beyond the peripheral edges 20, 60.

[0065] Sheets 3, 4, 5 and panes 2, 6 of glazing 1 are each in one piece.

[0066] The inner pane 6 is a monolithic glass sheet having a thickness of between 3.0 and 8.0 mm, for example 5.0 mm.

[0067] The outer pane 2 is laminated and comprises, starting from the outer space E: at least one outer glass sheet 3, one inner glass sheet 5, as well as a plastic sheet 4 located between the outer glass sheet 3 and the inner glass sheet 5, each sheet 3, 4, 5 of the outer pane 2 having a peripheral edge 30, 40, 50.

[0068] The outer glass sheet 3 has an outer face 31 which is oriented towards the outside E, an intermediate face 32 which is oriented towards the interlayer plastic sheet 4, with the peripheral edge 30 located between these two faces.

[0069] The inner glass sheet 5 has an intermediate face 51 which is oriented towards the plastic sheet 4, an inner face 52 which is oriented towards the glazing cavity 8, with the peripheral edge 50 located between these two faces.

[0070] The plastic sheet 4 has an outer intermediate face 41 which is oriented towards the intermediate face 32 and which is here in contact with this intermediate face 32, an inner intermediate face 42 which is oriented towards the intermediate face 51 and which is here in contact with this intermediate face 51, with the peripheral edge 40 which is located between these two intermediate faces 41, 42.

[0071] The outer glass sheet 3 is for example a glass sheet having a thickness of between 0.5 and 8.0 mm, for example 6.0 mm.

[0072] The interlayer plastic sheet 4 is, for example, a polyvinyl butyral (PVB) sheet having a thickness of between 0.50 and 1.50 mm, for example 0.76 mm. This plastic sheet 4 preferably has the same length and height dimensions as the outer glass sheet 3.

[0073] The inner glass sheet 5 is a glass sheet having a thickness of between 0.5 and 8.0 mm, for example 5.0 mm.

[0074] Here, glazing 1 thus has a total thickness t' of 26.76 mm.

[0075] The glazing 1 is a fixed glazing in the sense that the internal structure 7 is also intended to allow the glazing 1 to be fixed to a structure 9 of the means of transport (here the train), without the possibility of moving relative to this structure 9.

[0076] The glazing 1 is a multiple glazing in the sense that it comprises several panes 20, 60 as well as the glazing cavity 8 which is located between the two panes 20, 60, this cavity being filled with air or gas, preferably neutral such as argon or krypton; this cavity contributes to the thermal insulation provided by the glazing 1.

[0077] The internal structure 7 thus makes it possible to keep the two panes 20, 60 at a distance from each other, with a constant distance between the two panes 20, 60, here 10.0 mm.

[0078] The internal structure 7 comprises a hooking cavity 77 having a centripetal bottom 78 and a centrifugal opening 79.

[0079] This attachment cavity 77 preferably has a depth p, that is to say a distance between its centripetal bottom 78 and its centrifugal opening 79, of between 2.0 and 15.0 mm, preferably between 3.0 and 10.0 mm and here 7.0 mm.

[0080] The bay 9 comprises an outer flank 91, oriented vertically and facing the exterior space, an inner flank 92, oriented vertically and facing the exterior space, these two flanks being connected by a crosspiece 90, horizontal along the horizontal edges and vertical along the vertical edges. Although this is not illustrated, this crosspiece can also be oblique or cross-shaped. This connection forms an application space 95, in which the glazing is positioned and then fixed during its installation in the bay that it is to close.

[0081] Bay 9 is thus peripheral: it goes all the way around glazing 1.

[0082] When the glazing is fixed to the bay, the inner flank 92 extends in a centripetal direction, more centripetal than the edge 60 of the inner pane 6 and it has a fixing hole 93 which is located more centrifugally than the edge 60 of the inner pane 6; this fixing hole 93 has an axis A9 parallel to the edge 60 of said inner pane 6; that is to say horizontal.

[0083] A lock 10 is fixed to the inner flank 92 by a fixing means 104, such as for example a bolt having a head 105, and on the other side of the inner flank 92 by a nut 106. This bolt passes through the fixing hole 93 and the head 105 is thus located in the application space 95. The lock 10 has a body 11, cylindrical, hollow, oriented horizontally inside which the fixing means 104 passes freely and a lateral wing 12 (and preferably comprises a single lateral wing) extending from the body 11 in the direction of the center of the glazing in the fixed state, inside the attachment cavity 77 and opposite an edge of the intermediate face 61 of the inner pane 6.

[0084] This fixed state of the glazing is achieved by rotating the lock 10 90° on itself, around the axis of the fixing hole 93.

[0085] For proper fixing of the glazing, it is preferable to use several locks and in particular several locks along each edge of the glazing. The interval i between two adjacent locks is preferably between 100.0 and 400.0 mm, more preferably between 200.0 and 300.0 mm.

[0086] As seen more particularly on the figures 2 à 4 , the internal structure 7 comprises means for creating and maintaining the existence of the glazing cavity 8 and maintaining the glazing in the bay and the internal structure 7 comprises: an internal spacer 71 which is located between the inner glass sheet 5 and the inner pane 6, an internal bead of mastic 76, located between the inner glass sheet 5 and the inner pane 6 more peripherally than the spacer 71, an internal, elongated, U-shaped rail 75, extending between the edge of the intermediate face 22 and the edge of the face 61 and thus having a bottom oriented towards the glazing cavity 8 and an opening oriented in the opposite direction, in order to form the attachment cavity 77, and possibly an internal bead of glue 73, for gluing the rail 75 on the one hand to the intermediate face 22 of the outer pane 2 and on the other hand to the intermediate face 61 of the inner pane 6.

[0087] Preferably, the rail 75, and thus the hooking cavity 77, is not in direct contact with the edge of the intermediate face 22 and the edge of the face 61. The rail 75 is preferably embedded in the bead of glue 73.

[0088] Although this is not illustrated, instead of an elongated rail present along each edge of the glazing, it is possible to provide that said attachment cavity is formed by a groove located at the location of each lock; thus, between two localized grooves, the bead of mastic 76 fills the entire space between, on the one hand, the spacer 71 and, on the other hand, the edge between the edge 20, 60 and respectively the intermediate face 22, 61.

[0089] The spacer 71 is located set back from the edges 50, 60 of the inner glass sheet 5 and the inner pane 6, towards the center of the glazing, while being spaced apart, when the glazing is seen in cross-section, by a distance e further at the periphery than the transverse continuity of the edge 60 of the inner pane 6. This distance e is preferably between 10.0 and 50.0 mm, and more preferably between 10.0 and 40.0 mm, or even between 20.0 and 30.0 mm; here it is 24.0 mm; which provides a satisfactory glazing clearance.

[0090] The spacer 71 may be, for example, made of plastic and / or metal and / or metal alloy; it makes it possible to maintain the two panes 2, 6 at a constant distance from each other and to maintain the glazing cavity 8.

[0091] The spacer 71 is held in position against the intermediate face 61 of the inner window 6 and against the inner face 52 of said inner window 5 by means of the bead of mastic 76.

[0092] The glazing 1 does not include a frame, and in particular no rigid metal frame, which would hold the panes 2, 6 respectively both by the outer face 21 and by the inner face 62.

[0093] The inner flank 92 is preferably not directly in contact with the edge of the inner face 62 of the inner pane 6 thanks to the presence of an inner sealing bead 70; the inner sealing bead 70 is preferably in one piece and, more preferably, is not in contact with the edge 60 of the inner pane 6. It is preferably prefabricated and then glued against the edge of the inner face 62.

[0094] The bead of mastic 76, alone or with the bead of glue 73, preferably fills all the rest of the space except for the space created by the attachment cavity 77, and this in the transverse direction between the intermediate face 62 of the inner pane 6 and the intermediate face 22 of the outer pane 2 and preferably all the space in height between on the one hand the spacer 71 and on the other hand the edge between the edge 60 and the face 61.

[0095] Said bead of glue may comprise or be a bead of glue based on polyurethane or silicone or MS polymer (i.e. silane modified polyether) or polysulfide, so that the chemical bond with at least the inner pane is strong and preferably the chemical bond with the two panes on either side of the glazing cavity is strong.

[0096] The adhesive bead may comprise a metal profile which is glued laterally on each side of the glazing cavity, with such an adhesive bead or be partly or completely integrated into such an adhesive bead.

[0097] The bead of glue could comprise a cable, and in particular a metal cable, which is glued laterally on at least one side of the glazing cavity, in order to facilitate the breaking of the glass by pulling on this cable.

[0098] The outer flank 91 is preferably located in the continuity of appearance (i.e. here vertically) of the outer face 31 of the outer glass sheet 3, i.e. in the continuity of appearance of the outer face 21 of the outer pane 2, which is also the outer face 101 of the glazing 1.

[0099] The outer seal 98 is flush with the outer face 31 of the outer glass sheet and does not extend further outward than this outer face 31.

[0100] The outer seal 98 preferably does not fill the entire space between the outer flank 91 and the edge 20 of the outer pane 2 so that it is easy to remove to access the head 105.

[0101] It has been verified that adequate thermal insulation is achieved based on the example of the figure 1 , when said glazing cavity 8 is in one piece, that it is filled with argon and has a uniform thickness. The distance between the outer face 101 and the inner face 102 is thus constant and is here 28.76 mm.

[0102] It has been verified that appropriate mechanical strength is achieved based on the example of the figure 1 when glazing 1 is subjected to conditions similar to those it would undergo if it were integrated into a train traveling at 160 km / h.

[0103] The fixing according to the invention of the glazing 1 illustrated in figure 1 is particularly compact according to its thickness because the total thickness t of this fixing is almost that of the thickness of the glazing and no element of the glazing protrudes more outside or more inside than the thickness of this frame 72.

[0104] In figures 2 à 4 below, the total thickness t of the attachment is 31.8 mm. This total thickness represents the depth of the bay. Such a small bay depth increases the available space inside the means of transport.

[0105] In a first embodiment illustrated in figures2 And 3, the opening of the rail 75, and thus the opening of the hooking cavity 77, in the centrifugal direction is in the extension of the edges 20 and 60.

[0106] In the first embodiment of figures 2 and 3, the outer window 2 is as large as the inner window 6, both in length, along the X axis and in height along the Y axis.

[0107] In the first embodiment of the figures 2 And 3 , the edge 20 of the outer pane 2 or the edge 50 of the inner glass sheet 5 comprises a centrifugal lip 73 made of plastic material which extends, in the application space 95, in the direction of the crosspiece 90.

[0108] In the first embodiment, the lateral wing 12 of the lock 10 enters the hooking cavity 77 by simple and direct rotation of the lock 90° on itself.

[0109] In a second embodiment, the outer pane 2 is larger than the inner pane 6, both in length, along the X axis and in height along the Y axis in order to allow a part of the lock 10 to be hidden behind a peripheral edge of the outer pane 2. More precisely here, the outer glass sheet 3 is larger than the inner pane 6, both in length, along the X axis and in height along the Y axis. This allows a part of the lock 10 to be hidden behind a peripheral edge of this outer glass sheet.

[0110] Thus, the edge 30 of said outer glass sheet 3 is located in a centrifugal overhang d of the edge 60 of the inner pane 6 along at least part of the length of the edge 30 of said outer glass sheet 3 and preferably along the entire length of the edge 30 (i.e. along the entire periphery of the edge 30) of the outer glass sheet 3; if the outer pane 2 were monolithic (and not laminated), it could be the edge 20 of the outer pane which would be located in the overhang.

[0111] Thus, when the outer pane 2 is observed from the front, the overhang d is preferably present all around the outer pane 2: the edge 30 of the outer glass sheet 3 extends further, in the opposite direction to the center of the outer pane 2, than the edge 60 of the inner pane 6. This overhang d is preferably constant along a longitudinal or lateral edge considered; it is preferably identical along each of the longitudinal and lateral edges of the outer pane 2.

[0112] The overhang d is preferably between 5.0 and 30.0 mm, and preferably between 8.0 and 20.0 mm; here it is 13.0 mm.

[0113] This overhang d can be hidden from the view of the exterior space E by a layer of enamel located around the outer face 21 of the outer pane (or around the outer face 31 of the outer glass sheet, respectively when the outer pane is laminated).

[0114] In this second embodiment, in addition and independently of the overhang d above, the inner glass sheet 5 is smaller than the inner pane 6, both in length, along the X axis and in height along the Y axis.

[0115] When the laminated outer pane 2 is considered in section, the edge 50 of the inner glass sheet 5 is located set back r, centripetal, from the edge 30 of the outer glass sheet 3 over at least part of the length of the edge 50 of the inner glass sheet 5 and preferably over the entire length of the edge 50 of the inner glass sheet 5.

[0116] Thus, when the outer pane 2 is observed from the front, the shrinkage r is preferably present all around the outer pane 2: the edge 50 of the inner glass sheet 5 is more towards the center of the outer pane 2 than the edge 60 of the inner pane 6. This shrinkage r is preferably constant along a longitudinal or lateral edge considered; it is preferably identical along each of the longitudinal and lateral edges of the outer pane 2.

[0117] The shrinkage r is preferably between 1.0 and 10.0 mm, and preferably between 2.0 and 8.0 mm; here it is 5.0 mm.

[0118] This withdrawal r can be hidden from the view of the exterior space E by a layer of enamel located around the outer face 21 of the outer pane (or around the outer face 31 of the outer glass sheet, respectively when the outer pane is laminated).

[0119] In figure 4 , the opening of the rail 75, and thus the opening of the hooking cavity 77, in the centrifugal direction is in the extension only of the edge 60 of the inner window 6.

[0120] In figure 4 , the bead of mastic 76 preferably fills the entire space in the transverse direction between the inner face 62 of the inner pane 6 and the face 52 of the inner glass sheet 5, further extending into contact with the edge 50 of this inner glass sheet 5, the edge 40 of the plastic sheet 4, and the face 32 of the outer glass sheet 3 but without extending as far as the edge 30.

[0121] On this figure 4 , the bead of mastic 76 preferably fills the entire space in height between, on the one hand, the spacer 71 and, on the other hand, the edge between the edge 60 and the face 61.

[0122] In the second embodiment, the lateral wing 12 of the lock 10 enters the hooking cavity 77 by eccentric rotation of the lock 90° on itself.

[0123] This rotation is eccentric so that said wing moves away from the axis A9 of the fixing hole 93 during the penetration movement of the wing 12 into the attachment cavity.

[0124] This eccentric rotation can be achieved by providing on the one hand an oval washer 94 between the body 11 of the lock and the inner flank 92 and on the other hand a cylindrical recess in the wall of the body 11 which is opposite.

[0125] THE figures 5 et 6 illustrate a lock 10 with centered rotation: the body 11 of the lock is a hollow cylinder pierced with a cylindrical tube coaxial with the axis of the cylinder of the body, for the passage of the fixing means 104.

[0126] These figures show in particular that the wing 12 of the lock can have a chamfer 13, for example at 45°, in order to facilitate its passage into the attachment cavity 77 and come into contact, or almost into contact, with the bottom 78.

[0127] The wing here has a width 112 of 13.0 mm. The length between the axis of the lock and the end of the wing 12 is approximately 26 mm.

[0128] The wing 12 here penetrates into the attachment cavity 77 over the entire internal height of the rail 75, i.e. over a height of approximately 7 mm.

[0129] THE figures 7 et 8 illustrate a lock 10 with eccentric rotation, identical to the previous one except that, for the passage of the fixing means 104, the body 11 is a hollow cylinder pierced with a cylindrical tube which is not coaxial with the axis of the cylinder of the body: the axis of the cylindrical tube is offset laterally relative to the longitudinal orientation of the wing 12.

[0130] In both embodiments of the above lock, the lateral wing 12 is integral with the body 11.

[0131] Figures 9 to 11 illustrate a third variant embodiment of the lock in which the wing 12 is separated from the body 11.

[0132] This wing 12 also preferably has an oblong reservation 17 which accommodates the head 105 of the fixing means. There figure 9 illustrates the wing 12 before its positioning in the hanging cavity. The wing 12 is entirely in the application space 95. The figure 10 illustrates the wing 12 positioned in the attachment cavity, after a 90° rotation. The figure 11 is a view identical to the figure 10 , but in perspective.

[0133] This third variant makes it possible to maintain the wing 12 in an extended position along the application space 95, as visible in figure 9, the time to introduce or remove the glazing 1 (for example if it has been broken during use of the means of transport) into or out of the bay 9.

[0134] In this variant, only said lateral wing 12 is rotated through 90°; the rest of the lock, and in particular the body 11, is immobile.

[0135] The present invention is described in the foregoing by way of example. It is understood that a person skilled in the art is able to carry out different variants of the invention without departing from the scope of the patent as defined by the claims.

[0136] In particular, it is included in the present invention that the inner pane 6 can itself be laminated.
