Description

TECHNICAL FIELD

[0001] The present invention relates to the fixing of a side glazing of a vehicle, and notably of a train, to a peripheral window well, generally metallic. The fixing of the glazing is achieved by means of a lock which has a wing which extends, by a rotation of 90° of said wing, to the inside of an attachment cavity, facing the edge of the median face of the internal glazing. Such glazings are generally fixed in vertical position to the window well of a train. BACKGROUND

[0002] International patent application No. WO 2021 / 160962 discloses a glazing employing such a fixing, accessible from the outside of the vehicle. SUMMARY

[0003] Technical problem

[0004] The aim of the present invention is to overcome the drawbacks of the prior art by proposing a fixing system which allows easier checking of the position of the lock.

[0005] Solution to the technical problem

[0006] To this end, the invention relates, in its broadest sense, to a fixing system of a side glazing of a vehicle, notably of a train, to a peripheral window well according to claim 1. The glazing in question is thus a fixed multi-layer glazing, having an external face facing the outside space and an internal face facing the inside space, the external face of the glazing having an appearance continuity with the external flanc of the window well on the entire periphery of the window well, the glazing comprising:

[0007] - an external glazing pane having an external face facing the outside space, a peripheral side and a median face opposite the external face, the external glazing pane being preferably laminated and thus comprising at least one external glass sheet, an internal glass sheet and a sheet of plastic material located between the external glass sheet and the internal glass sheet, each sheet of the external glazing pane having a peripheral side,

[0008] - an internal glazing pane having an internal face facing the inside space, a median face opposite the internal face, and a peripheral side,

[0009] - an internal structure which, by being located at least partially closer to the centre of the glazing than the respective peripheral sides of the outer pane and of the inner pane, is on the inner periphery of the outer pane and on the inner periphery of the inner pane, and which holds the two panes together so that the glazing separates the outer space from the inner space by means of a glazing cavity located between the panes, the window hole comprising a lock fixed to the window hole and more centrifugal than the side of the inner pane, the lock having a wing which, by rotating the wing by 90°, extends to the inside of the attachment cavity and faces the edge of the median face of the inner pane, a preferably hollow external sealing gasket being located in the wall space between the outer side and the side of the outer pane or of the outer pane sheet, the external sealing gasket having an internal face.

[0010] The fixing system according to the application is remarkable in that the lock comprises at least one protrusion, and preferably a first protrusion and a second protrusion, which extend towards the outer space, the external sealing gasket comprising a groove which extends from the internal face towards the outer space,

[0011] - the protrusion and preferably the protrusions are intended to be housed in the groove when the wing is arranged in the attachment cavity, the lock being in a locked position, and

[0012] - the protrusion and preferably the protrusions are intended to rest on the internal face of the external sealing gasket when the lock is in a position other than the locked position.

[0013] The advantage of the fixing system according to the application is that it facilitates checking the position of the lock without any disassembly, in particular of the external sealing gasket. A person located outside the vehicle compartment, such as a dispatcher present on the platform of the railway station on which the vehicle compartment is located, sees that the sealing gasket is misaligned with respect to the window hole, and immediately realizes that there is an anomaly concerning the glazing of the vehicle compartment, without needing to know the fixing system according to the application. Furthermore, the application simplifies the technical intervention to be performed on the glazing, since it is not necessary to check all the locks present, but only the lock concerned for which the misalignment of the external sealing gasket has been determined.

[0014] When a single protrusion is used, the position of the lock other than the locked position causes a local bulge of the external sealing gasket at the position where the protrusion rests on the internal face of the external sealing gasket.

[0015] When two protrusions are used, any position of the lock other than the locked position causes a significant bulge at the position where the two protrusions rest on the internal face of the external sealing gasket.

[0016] In the meaning of the present application, the concept of appearance continuity means that the two surfaces present continuity with each other when viewed from the outside space. In practice, due to manufacturing tolerances, a height difference of up to 1 mm can be measured. Despite the need, in practice the glass window cannot reach a value of 0.0 mm class 100%; this is well known to the person skilled in the art.

[0017] Preferably, the external gasket has a thickness, the protrusion and preferably the length of the protrusion(s) is less than the thickness of the external gasket.

[0018] In the locked position, the protrusion and preferably each protrusion thus enters into the recess present on the external gasket without colliding with the bottom of the recess to avoid moving it and causing an unnecessary misalignment that can cause the person controlling the gasket to make a mistake.

[0019] Preferably, the length of the protrusion and more preferably of the protrusion(s) is at least equal to 25% of the thickness of the external gasket, or at least equal to 50% of the thickness of the external gasket.

[0020] Preferably, the recess is arranged in the middle of the external gasket along the height of the external gasket.

[0021] This arrangement of the recess has the advantage of easily accommodating the protrusion present on the locker.

[0022] Advantageously, the end of the protrusion or of each protrusion has a rounded corner.

[0023] The rounded corner at the end of the protrusion allows contact with the internal face of the external gasket without damaging it. Indeed, the gasket is made of a plastic material that can easily degrade by contact with the shape of the protrusion.

[0024] Preferably, the lateral wing has a pointed end having an angle between 60° and 120° in front view, preferably between 80° and 100°, even more preferably between 85° and 95°.

[0025] Thus, the recess has a width and the thickness of the protrusion or of each protrusion is between 0.8 and 1.1 times the width of the recess.

[0026] Thus, the protrusion can easily enter into the recess of the external gasket. BRIEF DESCRIPTION OF DRAWINGS

[0036] In the embodiments of the application, the use of a window pane or glass sheet is described. Each window pane can be monolithic, i.e. consist of a single sheet, or composite, i.e. consist of several sheets, in the case of a laminated glazing, these sheets being inserted between at least one interlayer of adhesive material. The sheet(s) can be inorganic, in particular glass, for example annealed or tempered, or organic, in particular a plastic material, for example polyvinyl butyral. The interlayer preferably contains at least one thermoplastic plastic material, preferably polyvinyl butyral (PVB), ethylene-vinyl acetate (EVA) and / or polyethylene terephthalate (PET). However, the thermoplastic interlayer can also contain, for example, polyurethane (PU), polypropylene (PP), polyacrylate, polyethylene (PE), polycarbonate (PC), polymethyl methacrylate, polyvinyl chloride, polyacetate, casting resin, acrylate, fluorinated ethylene propylene, polyfluoroethylene and / or ethylene-tetrafluoroethylene, or a copolymer or mixture thereof. The thermoplastic interlayer can be formed from one or more superimposed thermoplastic films, the thickness of the thermoplastic films preferably not exceeding 1 mm, in particular from 0.25 mm or 0.5 mm to 1 mm or 0.9 mm, generally of the order of 0.4 mm or 0.7 mm.

[0037] Figure 1 A left-hand side glazing 1 according to the application of a vehicle is shown, this glazing being positioned vertically and fixed to a window aperture 9 of the body of the vehicle.

[0038] It is in particular a side glazing of a train.

[0039] This glazing thus achieves a vertical separation between an interior space I inside the train and an exterior space E outside the train. Figure 1 Schematic view from the outside.

[0040] This glazing thus achieves a vertical separation between an interior space I inside the train and an exterior space E outside the train.

[0041] As it is a side glazing, it extends approximately along an axis generally called the "X axis" of the vehicle, which is the central axis of the longitudinal progression of the vehicle in which the glazing according to the application is fitted as a side glazing (here, left-hand side) and corresponds to the X axis in Figure 1 The Y axis is the vertical axis and the Z axis is the horizontal axis.

[0042] In the framework of the present text, the concepts of "centripetal" and "centrifugal" are considered in the plan view of the sheet in Figure 1 or, when considering the glazing as flat, in the general view of the glazing expressed along the X and Y axes relative to the centre of the glazing; the centripetal direction is the direction towards the centre, while the centrifugal direction is the direction away from the centre.

[0043] With reference to Figure 2 which is shown schematically Figure 1 The glazing 1 shown is a lower partial cross-sectional view. The window opening 9 is not shown. This glazing 1 is fixed. It is monolithic, without a sash that opens towards the interior, like for example known from international patent application No. WO 2016 / 042270; thus, although not described in detail here, the present application is applicable to such glazings with an openable sash.

[0044] This glazing 1 has an exterior face 101 facing the exterior space E and an interior face 102 facing the interior space I.

[0045] This glazing 1 comprises:

[0046] - an exterior pane 2 having an exterior face 21 facing the exterior space E, an intermediate face 22 opposite the exterior face, and a peripheral side face 20,

[0047] - an interior pane 6 having an interior face 62 facing the interior space I, an intermediate face 61 opposite the interior face, and a peripheral side face 60, and

[0048] - an interior structure 7, and which holds the two panes together, thereby enabling the glazing to delimit between the exterior space and the interior space by forming a glazing cavity 8 located between the panes 2, 6.

[0049] The interior structure 7 is qualified as "interior" in that it is located on the inner periphery of the exterior pane 2 and on the inner periphery of the interior pane 6 by being at least partially, and preferably entirely, closer to the center (more centripetally) than the respective peripheral side faces 20, 60 of the exterior pane 2 and of the interior pane 6; that is to say that the interior structure 7 does not overstep the peripheral side faces 20, 60 in a centrifugal direction.

[0050] The sheets 3, 4, 5 of the glazing and the panes 2, 6 of the glazing 1 are each monolithic.

[0051] The interior pane 6 is a single sheet of glass having a thickness between 3.0 and 8.0 mm, for example 5.0 mm.

[0052] The exterior pane 2 is preferably laminated and thus comprises, from the exterior space E: at least one exterior sheet of glass 3, an interior sheet of glass 5, and a sheet of plastic material 4 located between the exterior sheet of glass 3 and the interior sheet of glass 5, each sheet 3, 4, 5 of the exterior pane 2 having a peripheral side face 30, 40, 50.

[0053] The outer glass sheet 3 has an outer face 31 oriented towards the outside space E, a sandwiched interlayer face 32 oriented towards the plastic material sheet 4, with the peripheral side face 30 being located between these two faces.

[0054] The inner glass sheet 5 has an interlayer face 51 oriented towards the plastic material sheet 4, an inner face 52 oriented towards the glass window cavity 8, with the peripheral side face 50 being located between these two faces.

[0055] The plastic material sheet 4 has an outer interlayer face 41 oriented towards and in contact with the interlayer face 32, an inner interlayer face 42 oriented towards and in contact with the interlayer face 51, with the peripheral side face 40 being located between these two interlayer faces 41, 42.

[0056] The outer glass sheet 3 is for example a glass sheet having a thickness between 0.5 and 8.0 mm, for example 6.0 mm.

[0057] The interlayer plastic material sheet 4 is for example a polyvinyl butyral (PVB) sheet having a thickness between 0.50 and 1.50 mm, for example 0.76 mm. This plastic material sheet 4 is preferably of the same length and height dimensions as the inner glass sheet 5.

[0058] The inner glass sheet 5 is a glass sheet having a thickness between 0.5 and 8.0 mm, for example 5.0 mm.

[0059] Here, the glass window 1 thus has a total thickness t’ of 26.76 mm.

[0060] The glass window 1 is a fixed glass, meaning that the inner structure 7 is also intended to allow the glass window 1 to be fixed to a window hole 9 of a vehicle, here a train, and not to be able to move with respect to the window hole 9.

[0061] The glass window 1 is a multiple glazing, meaning that it comprises a plurality of windowpanes 2, 6 and glass window cavities 8 located between two windowpanes 2, 6, the cavities being filled with air or a gas, preferably a neutral gas such as argon or krypton; the cavities contribute to the glass window 1 having a thermal insulation effect.

[0062] The inner structure 7 thus allows the two windowpanes 2, 6 to be held at a distance from each other, with the distance between the two windowpanes 2, 6 being constant, here 10.0 mm.

[0063] Reference will now be made to Figure 3The window opening 9 comprises: an exterior side 91 oriented vertically and turned towards the exterior space; an interior side 92 oriented vertically and turned towards the interior space, the two sides being connected by a crosspiece 90, horizontal along the horizontal edges of the glazing and vertical along the vertical edges of the glazing. Although not illustrated, this crosspiece can also be diagonal or cruciform. This connection forms a wall space 95 in which the glazing is positioned and then fixed when it is installed in the window opening that it is intended to close.

[0064] The window opening 9 is therefore peripheral: it surrounds the entire glazing 1.

[0065] The window opening 9 comprises a lock 10 fixed or attached to the window opening and more peripheral than the side 60 of the interior pane 6. This lock 10 has a wing 12 that extends by 90° of rotation of the wing 12 to the interior of the attachment cavity 77 and faces the edge of the median face 61 of the interior pane 6 in order to constrain the glazing. This or each lock can both fix the glazing and constrain it in order to replace it with another glazing when it is necessary to replace the glazing, while keeping the lock fixed directly or indirectly to the window opening.

[0066] More particularly as illustrated in Figure 2 The interior structure 7 comprises means for forming and maintaining the presence of the glazing cavity 8 and for holding the glazing on the window opening, and the interior structure 7 comprises:

[0067] - an interior spacer 71 between the interior glass sheet 5 and the interior pane 6,

[0068] - an interior mastic cord 76 between the interior glass sheet 5 and the interior pane 6, more peripheral (more centrifugal) than the spacer 71,

[0069] - a U-shaped elongated interior rail 75 extending between the edge of the median face 22 and the edge of the median 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 an attachment cavity 77, and

[0070] - optionally an interior strip of glue for gluing the rail 75 both on the median face 22 of the exterior pane 2 and to the median face 61 of the interior pane 6.

[0071] Preferably, the rail 75 and the attachment cavity 77 are not in direct contact with the edge of the median face 22 and the edge of the face 61. The rail 75 is preferably embedded in the strip of glue. The rail 75 can be made of metal or a metal alloy.

[0072] Although not shown, it can be provided that the attachment cavities are formed by grooves located at each lock, instead of elongated tracks along each edge of the glazing; thus, between the two grooves of positioning, the filler strip 76 fills the space between the spacer 71 and the edge between the side faces 20, 60 and the respective intermediate faces 22, 61.

[0073] The spacer 71 recedes from the side faces 50, 60 of the inner pane 5 and of the inner glass 6 towards the center of the glazing, while being offset e from the lateral continuity of the side face 60 of the inner glass 6 when the glazing is observed in cross section. This offset 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; this gives the glazing a satisfactory transparency.

[0074] The spacer 71 can be, for example, of plastic material and / or metal and / or metal alloy; it allows the two panes 2, 6 to be held at a constant distance from each other and to maintain the glazing cavity 8.

[0075] The spacer 71 is held in position against the intermediate face 61 of the inner glass 6 and against the inner face 52 of the inner pane 5 with the filler strip 76.

[0076] The glazing 1 does not comprise a frame, and in particular a metal rigid frame, which holds the panes 2, 6 respectively by the outer face 21 and by the inner face 62.

[0077] The inner side 92 is preferably not in direct contact with the edge of the inner face 62 of the inner glass 6, due to the presence of the inner sealing strip 70; the inner sealing strip 70 is preferably integrally formed and more preferably does not come into contact with the side face 60 of the inner glass 6. It is preferably preformed and then glued against the edge of the inner face 62.

[0078] The filler strip 76, alone or together with the adhesive strip, preferably fills all the remaining spaces, except those constituted by the attachment cavities 77, and it fills, in the transverse direction between the intermediate face 61 of the inner glass 6 and the intermediate face 22 of the outer pane 2, and preferably the entire upper space between the spacer 71 and the edge (between the side face 60 and the intermediate face 61).

[0079] The adhesive strip can comprise or be an adhesive strip based on polyurethane or silicone or MS polymer (i.e. modified polyether silane) or polysulfide, so that the chemical bond with at least the inner glass is firm, and preferably so that the chemical bond with both panes on either side of the glazing cavity is firm.

[0080] The sealing strip may include a metal profile that is laterally bonded to each side of the glass window cavity through the sealing strip, or is partially or wholly integrated into the sealing strip.

[0081] The adhesive strip may include a cable, and in particular a metal cable, which is laterally bonded to one side of at least one glass cavity to allow the window glass to be easily broken by pulling the cable.

[0082] The outer side 91 is preferably within the appearance continuity of the outer surface 31 of the outer glass sheet 3 (that is, it is vertical here), that is, within the appearance continuity of the outer surface 21 of the outer window glass 2 (which is also the outer surface 101 of the glass window 1).

[0083] Preferably, the hollow outer sealing gasket 99 is located in the wall space 95 between the following, and preferably there is contact:

[0084] - The edge of the outer side 91 and the crossbar 90

[0085] - and the side 20 of the exterior window glass 2 (in the case of a single-pane exterior window glass) or as shown here Figure 2 The side 30 of the external window glass 3 shown.

[0086] - Preferably, it contacts the edge of the middle surface 22 of the outer window glass 2 (in the case of a single piece of outer window glass) or, as in this case, contacts the edge of the middle surface 32 of the outer glass sheet 3.

[0087] The height h of the external sealing gasket 99 is preferably between 5.0 and 30.0 mm, more preferably between 8.0 and 20.0 mm, for example 18.0 mm.

[0088] It has been confirmed that when the glass window cavity 8 is integrally formed, the cavity is filled with argon gas and has a uniform thickness, based on Figure 1 The example achieves adequate insulation. The distance between the outer surface 101 and the inner surface 102 is therefore constant and is 26.76 mm in this case.

[0089] The fastener preferably includes a plurality of side wings 12, which extend in a centripetal direction, that is, when their locking devices are locked, they extend towards the vertical central axis of the window so that the side wings extend horizontally, and when their locking devices are locked, they extend towards the horizontal central axis of the window so that the side wings extend vertically.

[0090] It has been confirmed that when window glass 1 is under conditions similar to those in a train traveling at 160 km / h, based on Figure 1 The examples in the text can achieve appropriate mechanical strength.

[0091] The glass window frame structure has no external structural part; it comprises only a part of the internal structure 7, and it is located on the inner periphery of the outer window pane 2 and on the inner periphery of the inner window pane 6 by being closer to the center (more centripetally) than the respective peripheral sides 20, 60 of the outer and inner window panes 2, 6, and it holds the two window panes together, thus enabling the glass window to separate the outer space E and the inner space I by the glass window cavity 8 located between the window panes 2, 6.

[0092] The side wing 12 of the lock 10 enters into the attachment cavity 77 by a simple and direct 90° rotation of the lock about itself.

[0093] When the glass window is fixed to the window hole, the internal side 92 extends in the centripetal direction more centripetally than the side 60 of the inner window pane 6, and it has a fixing hole 93 more centrifugally than the side 60 of the inner window pane 6; this fixing hole 93 has an axis A9 parallel to the side 60 of the inner window pane 6; i.e. horizontal.

[0094] The lock 10 is fixed to the internal side 92 by a fixing device 104, e.g. a screw with a screw head 105, and to the other side of the internal side 92 by a nut 106. The screw passes through the fixing hole 93, and the screw head 105 is thus in the wall space 95. The lock 10 has a hollow cylindrical body 11, which is oriented horizontally, with the fixing device 104 free inside it, and a side wing 12, and preferably comprises a single side wing, which in the fixed state extends from the body 11 in the centripetal direction of the glass window to the inside of the attachment cavity 77 and faces the edge of the middle surface 61 of the inner window pane 6.

[0095] The outer sealing gasket 99 preferably does not fill all the space between the outer side 91 and the side 20 of the outer window pane 2, thus making it easy to dismount to access the screw head 105 of the lock 10.

[0096] Figure 3 A preferred embodiment of the invention is shown. The lock 10 is shown in the locked position, the side wing 12 is thus placed in the attachment cavity 77. The outer sealing gasket 99 has an outer face 99a oriented towards the outer space E, an inner face 99d oriented towards the inner space I and has a thickness e 99In the locked position, the outer face 99a of the outer sealing gasket 99 is flush with the outer face 31 of the outer glass sheet 3 and does not extend further outward than this outer face 31. Although it is desirable that the outer face 99a of the outer sealing gasket 99 be flush with the outer face 31 of the outer glass sheet 3, there can be a deviation of between 0.5 mm and 1 mm between these two faces. The outer sealing gasket 99 is preferably made by molding around the glazing. The lock 10 comprises a first projection 10a and a second projection 10b, which can also be seen in Figures 5 to 7 The outer sealing gasket 99 comprises a recess 99c, preferably over its entire profile. Alternatively, the recess 99c is discontinuously present on the profile of the outer sealing gasket 99, facing each lock 10. The recess 99c extends horizontally along the horizontal edges of the glazing and vertically along the vertical edges of the glazing.

[0097] When viewed in cross section, the recess 99c extends from the inner face 99d toward the outer space E and has a depth p 99 and a width 1 99 The depth p 99 of the recess 99c is between 50% and 90% of the thickness e 99 of the outer sealing gasket 99. The length L (visible in Figure 5 ) of the first and second projections 10a, 10b is less than the thickness e 99 of the outer sealing gasket 99. Preferably, the length L is equal to at least 25% of the thickness e 99 , and even at least 50% of the thickness e 99 . Furthermore, the thickness e 10 of the first and second projections 10a, 10b is between 0.8 and 1.1 times the width 1 99 .

[0098] In the "lock-locked" position, the first and second projections 10a, 10b are located in the recess 99c. Indeed, during the rotation of the lock 10 about itself by 90°, the first and second projections 10a, 10b enter into the recess 99c. Thus, when the lock 10 is in the locked position, the outer sealing gasket 99 is flush with respect to the outer face 21 of the outer pane 2 (the outer face 31 of the outer glass sheet 3), with the just-mentioned deviation. The present invention thus allows the position of the lock 10 to be checked visually from the outside.

[0099] Conversely to the configuration in the locked position, visible in Figure 3 , in the "lock-unlocked" position, visible in Figure 4The configuration of the fixing system of the glazing 1 in the open position can be seen. When the lock 10 is in the open position, the side wing 12 is thus positioned at 90° from its position when the lock 10 is in the locked position. The first protrusion 10a has a contact surface at its end 10a' and the second protrusion 10b also has a contact surface at its end 10b'. Preferably, the ends 10a', 10b' are rounded. Alternatively, the ends 10a', 10b' are flat. In the open position, the ends 10a', 10b' are in contact with the inner face 99d of the outer seal 99. The first and second protrusions 10a, 10b are thus supported on the outer seal 99 so that its outer face 99a is offset in the direction of the outer space E with respect to the outer face 21 of the outer pane 2 (the outer face 31 of the outer glass sheet 3).

[0100] The advantage of the invention is thus to allow the position of the lock 10 to be checked simply from the outside of the space E. For example, a dispatcher located on a platform (one side of which is stopped by a carriage) can visually detect that the outer seal 99 protrudes beyond the outer face 21 of the outer pane 2 (the outer face 31 of the outer glass sheet 3). He can for example report this problem to the team in charge of the maintenance of the carriages so that this team intervenes to check the position of the lock 10 and can displace it to the locked position if necessary.

[0101] In the open position, the offset between the outer face 99a of the outer seal 99 and the outer face 31 of the outer glass sheet 3 is between 25% and 50% of the thickness of the outer seal 99. This offset is approximately equal to the length of the first and second protrusions 10a, 10b. In the invention, it is desirable for the outer seal 99 to be sufficiently offset with respect to the outer face 31 of the outer glass sheet 3 so that this offset is sufficiently visible and a problem relating to the position of the lock 10 can thus be detected. In other words, the invention is a mistake-proofing device. Indeed, during the installation of the glazing 1, it is possible for one or even several locks 10 to be inadvertently left unlocked. With the invention, this oversight can easily be detected.

[0102] The glazing frame structure additionally comprises an outer structure 7' which extends over the outer periphery of the outer pane 2 / over the outer periphery of the inner pane 6 further away from the centre of the pane (more centrifugally) than the respective peripheral side 20, 60 of the outer pane 2 and / or of the inner pane 6.

[0103] Here, the outer structure 7' is substantially h-shaped in cross-section, with a body 107 and two feet which extend more centrifugally from the body, the outer feet being shorter than the inner feet.

[0104] The outer structure 7' is additionally glued and fixed to the inner side 92 by means of a strip 97, optionally supplemented by a gasket or strip 108 located between the outer foot of the outer structure 7' and the outer side 91.

[0105] In Figure 4 and Figure 5 The outer structure 7' visible in the figures is a light outer structure, which means that it preferably extends over the outer periphery of the inner pane 6 only further away from the centre of the pane (more centrifugally) than the peripheral side 60 of the inner pane; it also extends over the outer periphery of the glass window cavity 8 further away from the centre of the pane (more centrifugally) than the glass window cavity, but it does not extend over the outer periphery of the outer pane 2 further away from the centre of the pane than the peripheral side 20 of the outer pane.

[0106] Furthermore, the outer structure 7' is a light outer structure, which means that it preferably does not come closer to the centre of the inner pane 6 (more centripetally) than the spacer 71, so that the transparency of the glazing is as high as possible.

[0107] The body 107 preferably does not directly contact the inner face 62 of the inner pane 6 due to the presence of the inner seal 70; the inner seal 70 is preferably integrally formed and more preferably does not contact the side 60 of the inner pane 6.

[0108] Although not shown, the outer pane 2 can be as large as the inner pane 6, both in length along the X axis and in height along the Y axis.

[0109] Although not shown, the side 20 of the outer pane 2 or the side 50 of the inner pane 5 can comprise a plastic material centrifugal lip which extends into the wall space 95 in the direction of the crosspiece 90.

[0110] The fixed state of the glazing is reached by rotating the lock 10 about the axis of the fixing hole 93 by 90° about itself.

[0111] In order to correctly fix the glazing, a plurality of locks is preferably used, and in particular a plurality of locks is used along each edge of the glazing. The spacing between two adjacent locks is preferably between 100.0 and 400.0 mm, more preferably between 200.0 and 300.0 mm.

[0112] 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, so as to allow a portion of the lock 10 to be hidden behind the peripheral edge of the outer pane 2. Here more precisely, the outer pane 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 portion of the lock 10 to be hidden behind the peripheral edge of the outer pane.

[0113] Thus, the side 30 of the outer glass sheet 3 is positioned to project outwards a projection p from the side 60 of the inner window pane 6 at least along a portion of the length of the side 30 of the outer glass sheet 3 and preferably along the entire length of the side 30 of the outer glass sheet 3, that is to say along the entire periphery of the side 30; if the outer window pane 2 is monolithic (rather than laminated), it can be that the side 20 of the outer window pane is positioned to project outwards a projection.

[0114] Thus, when the outer window pane 2 is viewed from the front, the projection p preferably completely surrounds the outer window pane 2: in the direction opposite the centre of the outer window pane 2, the side 30 of the outer glass sheet 3 extends further than the side 60 of the inner window pane 6. This projection p is preferably constant along the longitudinal or transverse edge in question; preferably it is the same along each longitudinal and transverse edge of the outer window pane 2.

[0115] This projection p is preferably between 5.0 and 30.0 mm, and preferably between 8.0 and 20.0 mm, for example 13.0 mm here.

[0116] This projection p can be hidden from view in the exterior space E by a layer of enamel located around the outer face 21 of the outer window pane (or around the outer face 31 of the outer glass sheet in the case where the outer window pane is laminated).

[0117] Furthermore and independently of the aforementioned projection p, the inner glass sheet 5 is smaller than the inner window pane 6, both in terms of length along the X axis and in terms of height along the Y axis.

[0118] When the laminated outer window pane 2 is viewed in cross-section, the side 50 of the inner glass sheet 5 is positioned to retract inwards a retraction r from the side 30 of the outer glass sheet 3 at least along a portion of the length of the side 50 of the inner glass sheet 5 and preferably along the entire length of the side 50 of the inner glass sheet 5.

[0119] Thus, when the outer window pane 2 is viewed from the front, the retraction r preferably completely surrounds the outer window pane 2: the side 50 of the inner glass sheet 5 is closer to the centre of the outer window pane 2 than the side 60 of the inner window pane 6. This retraction r is preferably constant along the longitudinal or transverse edge in question; preferably it is the same along each longitudinal and transverse edge of the outer window pane 2.

[0120] This retraction r is preferably between 1.0 and 10.0 mm, and preferably between 2.0 and 8.0 mm; for example 5.0 mm here.

[0121] This retraction 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 when the outer pane is laminated).

[0122] The opening of the track 75 and the opening of the attachment cavity 77 are in the centrifugal direction only in the extension of the side 60 of the inner pane 6.

[0123] In Figure 3 and Figure 4 , the filler strip 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, in addition by extending at the contact of the side 50 of this inner glass sheet 5, of the side 40 of the plastic material sheet 4 and of the face 32 of the outer glass sheet 3, but not up to the side 30.

[0124] In these Figure 3 and Figure 4 , the filler strip 76 preferably fills the entire upper space between the spacer 71 and the edge (between the side 60 and the face 61).

[0125] Figure 5 and Figure 7 The central rotating lock 10 is shown: the body 11 of the lock is a hollow cylinder, pierced by a post tube coaxial to the axis of the cylinder of the body, for the passage of the fixing means 104.

[0126] These figures notably show that the side wing 12 of the lock can have a pointed end 12a (opposite to the body 11), presenting an angle a in the front view, such as Figure 7 for example 90°, so as to facilitate its passage in the attachment cavity 77 and to contact or almost contact the bottom 78.

[0127] The side wing 12 also comprises an inclined inner face, presenting an angle b in the top view, such as Figure 6 and an angle Q in the front view, such as Figure 7 The shape of the side wing 12 allows to lock its rotation in both rotation directions by abutment against the walls of the attachment cavity 77.

[0128] The side wing 12 enters into the attachment hook cavity 77 over the entire internal length of this track 75, i.e. over a height of approximately 7 mm.

[0129] The side wing 12 of each lock is manufactured in the same material as the body 11.

[0130] The above is an exemplary description of the application. Note that the person skilled in the art can make various variants to the application on its own, without departing from the scope of the patent as described, for example, in the claims.

[0131] In particular, it is included in the present application that the inner pane 6 itself can be laminated.
