System for securing a side glazing of a means of transport with a lock having at least one anti-misrepresentation projection

Description

Technical field

[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. The fixing of the glazing is carried out by means of a lock having a lateral wing extending inside a hooking cavity opposite an edge of an intermediate face of the inner window by rotation of said lateral wing through 90°. This type of glazing is usually fixed to the bay of the train in a vertical position. Technological background

[0002] International patent application No. WO 2021 / 160962 discloses glazing with such an attachment, accessible from outside the means of transport. Summary of the invention Technical problem

[0003] The aim of the invention is to overcome the drawback of the prior art by proposing a fixing system which makes it easier to check the position of the lock. Solution to the technical problem

[0004] To do this, the invention relates, in its broadest sense, to 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. Said glazing is thus 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 side of said bay over its entire periphery, said glazing comprising:

[0005] - an outer pane having an outer face facing the outer space, a peripheral edge and an intermediate face opposite the outer face, 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 having an inner face facing the inner space, an intermediate face opposite the inner face, and 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 at least partly further towards the center of the glazing than the peripheral edge of said outer pane and said inner pane respectively, 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, said internal structure comprising a hooking cavity having a centripetal bottom and a centrifugal opening, said bay comprising a lock which is fixed to said bay and is located more centrifugally than the edge of said inner pane,said lock having a lateral wing extending inside said attachment cavity and facing an edge of said intermediate face of the inner pane by 90° rotation of said lateral wing, an external seal, preferably hollow, being located in an application space between on the one hand said external flank and on the other hand the edge of said outer pane or on the other hand the edge of said outer glass sheet, said external seal having an inner face.

[0006] The fixing system according to the invention is remarkable in that said lock comprises at least one projection, and preferably comprises a first projection and a second projection, extending towards the exterior space, said exterior seal comprising a groove extending from said interior face towards the exterior space, said projection, and preferably said projections, being intended to be housed in said groove when said wing is arranged in said attachment cavity, the lock being in the closed position, and said projection, and preferably said projections, being intended to bear on said inner face of said outer seal when the lock is in a position other than the closed position.

[0007] The fastening system according to the present invention has the advantage of facilitating the verification of the position of the lock, without any disassembly, in particular of the external seal. A person located outside the wagon, for example a controller present on the platform of the railway station where the wagon is located, seeing a misalignment of the seal with respect to the opening immediately realizes, even without knowing the fastening system of the present invention, that there is clearly an anomaly with regard to the glazing of the wagon. In addition, the invention simplifies the technical intervention to be carried out on the glazing because it is not necessary to check all the locks present, but only the one for which a misalignment of the external seal has been identified.

[0008] When only one projection is used, a position of the latch other than the closed position causes a localized dent in the outer seal where the projection presses against the inner face of said outer seal.

[0009] When two projections are used, any position of the latch other than the closed position causes a substantial dent where the two projections press against the inner face of said outer seal.

[0010] The concept of continuity of appearance within the meaning of the present invention means that visually, from the outside, the two surfaces appear to be continuous with each other. In practice, it is possible to measure a height difference of up to 1 mm due to manufacturing tolerances. Although desired, a value of 0.0 mm for 100% of the glazing units is not achievable in practice; this is well known to those skilled in the art.

[0011] Preferably, the outer seal has a thickness, said projection, and preferably said projections, have a length less than the thickness of said outer seal.

[0012] In the closed position, said projection, and preferably each projection, thus penetrates into the groove present on the external seal, without hitting the bottom of the groove so as not to move it and cause an unwanted misalignment which could mislead a person checking the seal.

[0013] Preferably, said projection, and more preferably said projections, have a length equal to at least 25% of the thickness of said external seal, or even at least 50% of the thickness of said external seal.

[0014] Preferably, said groove is arranged in the middle of said outer seal according to its height.

[0015] This arrangement of the groove has the advantage of easily accommodating the projections present on the lock.

[0016] Advantageously, one end of one or each projection has a rounding.

[0017] A rounded end of the projection allows contact to be made with the inner face of the outer seal without damaging it. In fact, the seal is made of a plastic material that can easily be damaged by contact with a protruding shape.

[0018] Preferably, said lateral wing has a pointed end presenting in a front view an angle of between 60° and 120°, preferably between 80° and 100°, even more preferably between 85° and 95°.

[0019] Preferably, said groove has a width, one or each projection has a thickness of between 0.8 and 1.1 times said width of the groove.

[0020] The projections can thus easily penetrate into the groove of the outer seal.

[0021] Several embodiments of the present invention will be described below, by way of non-limiting examples, with reference to the appended figures in which: [ Fig. 1 ] illustrates a perspective diagram of the exterior of a train body bay comprising multiple glazing fixed to the bay using a fixing system according to the invention, the system being illustrated without an external seal; [ Fig.2 ] illustrates a vertical cross-sectional diagram at the bottom of the glazing according to the [ Fig. 1 ], the bay not being represented; [ Fig.3 ] illustrates a vertical cross-sectional diagram at the bottom of the glazing, according to the Figures 1 and 2 , fixed to a bay by means of a lock according to a preferred embodiment of the invention, the lock being in the closed position and seen in complete section; [ Fig.4] schematically represents the glazing fixing system illustrated in the [ Fig.3 ] except that the lock is in the open position; [ Fig.5 ] schematically illustrates the lock according to the invention in side view; [ Fig.6 ] schematically illustrates the lock according to the invention in top view; [ Fig.7 ] schematically illustrates the lock according to the invention in front view.

[0022] In these diagrams, the proportions between the dimensions of the different elements are respected in order to facilitate their reading.

[0023] In the embodiments of the invention, the implementation of panes or sheets of glass is described. Each pane may be monolithic, i.e. made up of a single sheet of material, or be composite, i.e. made up of several sheets of material between which is inserted at least one intermediate layer of adherent material, in the case of laminated glazing. The sheet(s) of material may be mineral, in particular made of glass, for example having undergone annealing or tempering, or organic, in particular made of plastic such as polyvinyl butyral. The intermediate layer preferably contains at least one thermoplastic plastic, preferably polyvinyl butyral (PVB), ethylene vinyl acetate (EVA), and / or polyethylene terephthalate (PET).However, the thermoplastic intermediate layer may also contain, for example, polyurethane (PU), polypropylene (PP), polyacrylate, polyethylene (PE), polycarbonate (PC), polymethyl methacrylate, polyvinyl chloride, polyacetate resin, casting resins, acrylates, fluorinated ethylene-propylene, polyvinyl fluoride and / or ethylene-tetrafluoroethylene, or copolymers or mixtures thereof. The thermoplastic intermediate layer may be formed from one or more superimposed thermoplastic films, the thickness of a thermoplastic film preferably not exceeding 1 mm, in particular from 0.25 mm or 0.5 mm to 1 mm or 0.9 mm, typically around 0.4 mm or 0.7 mm.

[0024] There [ Fig. 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.

[0025] This is particularly the case for train side glazing.

[0026] This glazing thus creates a vertical separation between an interior space I which is inside the train and an exterior space E which is outside the train. The [ Fig. 1 ] is a schematic view of the exterior.

[0027] 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).

[0028] 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 in [ Fig. 1]. The Y axis is the vertical axis and the Z axis is the transverse axis.

[0029] 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 [ Fig. 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.

[0030] With reference to the [ Fig.2 ], the glazing 1 illustrated on the [ Fig. 1], partial sectional view, in a lower part. The bay 9 is not shown. The glazing 1 is fixed. It is in one 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.

[0031] 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.

[0032] 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 outer face, as well as a peripheral edge 20, 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.

[0033] 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 at least partly (and preferably entirely) 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.

[0034] Sheets 3, 4, 5 and panes 2, 6 of glazing 1 are each in one piece.

[0035] 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.

[0036] The outer pane 2 is preferably laminated and then 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.

[0037] The outer glass sheet 3 has an outer face 31 which is oriented towards the outer space E, an intermediate face 32 which is oriented towards the interlayer plastic sheet 4, with the peripheral edge 30 located between these two faces.

[0038] 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.

[0039] 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.

[0040] 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.

[0041] 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 inner glass sheet 5.

[0042] 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.

[0043] Here, glazing 1 thus has a total thickness t' of 26.76 mm.

[0044] 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 bay 9 of the means of transport (here the train), without the possibility of moving relative to the bay 9.

[0045] The glazing 1 is a multiple glazing in the sense that it comprises several panes 2, 6 as well as the glazing cavity 8 which is located between the two panes 2, 6, 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.

[0046] The internal structure 7 thus makes it possible to keep the two panes 2, 6 at a distance from each other, with a constant distance between the two panes 2, 6, here 10.0 mm.

[0047] Referring now to the [ Fig.3 ], the bay 9 comprises an outer flank 91, oriented vertically and facing the exterior space, an inner flank 92, oriented vertically and facing the interior space, these two flanks being connected by a crosspiece 90, horizontal along the horizontal edges of the glazing and vertical along the vertical edges of the glazing. 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.

[0048] Bay 9 is thus peripheral: it goes all the way around glazing 1.

[0049] The bay 9 comprises a lock 10 which is fixed, or attached, to the bay and is located more centrifugally than the edge 60 of the inner pane 6. This lock 10 has a lateral wing 12 extending inside the attachment cavity 77 and opposite an edge of the intermediate face 61 of the inner pane 6 by 90° rotation of the lateral wing 12 in order to retain the glazing. This lock, or each lock, makes it possible both to fix the glazing and to remove this glazing when it is necessary to change it to replace it with another glazing, while keeping the lock(s) fixed directly or indirectly to the bay.

[0050] As seen more particularly on the [ Fig.2 ], 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 (more centrifugally) 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 intermediate 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, 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.

[0051] 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. The rail 75 may be made of metal or a metal alloy.

[0052] 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.

[0053] 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 satisfactory glazing clarity.

[0054] 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.

[0055] 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.

[0056] 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.

[0057] 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.

[0058] The bead of mastic 76, alone or with the bead of glue, 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 61 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 intermediate face 61.

[0059] 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.

[0060] 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.

[0061] 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.

[0062] 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.

[0063] An outer seal 99, preferably hollow, is located in an applique space 95 between, preferably with contact, on the one hand the edge of the outer side 91 and the crosspiece 90 and on the other hand the edge 20 of the outer pane 2 (case of the monolithic outer pane) or on the other hand, as illustrated here on the [ Fig.2 ], the edge 30 of the outer glass sheet 3 while preferably being in contact with an edge of the intermediate face 22 of the outer pane 2 (case of the monolithic outer pane) or in contact, as here, with an edge of an intermediate face 32 of the outer glass sheet 3.

[0064] The outer seal 99 preferably has a height h of between 5.0 and 30.0 mm, preferably between 8.0 and 20.0 mm, for example 18.0 mm.

[0065] It has been verified that adequate thermal insulation is achieved based on the example of the [ Fig. 1], when said glazing cavity 8 is in one piece, 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 26.76 mm.

[0066] The fixing preferably comprises several lateral wings 12 which all extend in a centripetal direction, that is to say towards a vertical central axis of the glazing for the lateral wings extending horizontally when their locks are closed and towards a horizontal central axis of the glazing for the lateral wings extending vertically when their locks are closed.

[0067] It has been verified that appropriate mechanical strength is achieved based on the example of the [ Fig. 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.

[0068] The glazing frame structure has no external structural part; it only comprises an internal structural part 7 and which 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 the inner pane 6, and which holds these two panes together in such a way that the glazing creates a separation between the external space E and the internal space I with a glazing cavity 8 located between the panes 2, 6.

[0069] The lateral wing 12 of the lock 10 enters the hooking cavity 77 by simple and direct rotation of the lock 90° on itself.

[0070] 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.

[0071] The lock 10 is fixed directly to the inner flank 92 by a fixing means 104, such as for example a screw having a head 105, and on the other side of the inner flank 92 by a nut 106. The screw 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 towards 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.

[0072] The outer seal 99 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 screw head 105 of the lock 10.

[0073] It is represented on the [ Fig.3] a preferred embodiment of the present invention. The lock 10 is shown in the closed position, the side wing 12 being consequently arranged in the hooking cavity 77. The outer seal 99 has an outer face 99a oriented towards the outer space E, an inner face 99d oriented towards the inner space I and a thickness e 99 . In the closed position, the outer face 99a of the outer seal 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 desired that the outer face 99a of the outer seal 99 and the outer face 31 of the outer glass sheet 3 be flush, there may nevertheless be a gap of between 0.5 mm and 1 mm between these two faces. The external seal 99 preferably goes all the way around the glazing and is in one piece.The lock 10 comprises a first projection 10a and a second projection 10b, also visible on the . figures 5 to 7 , preferably arranged on the periphery 10c of the lock 10. The outer seal 99 comprises a groove 99c present, preferably, over its entire periphery. Alternatively, the groove 99c is present discontinuously around the periphery of the outer seal 99, opposite each lock 10. The groove 99c extends horizontally along the horizontal edges of the glazing and vertically along the vertical edges of the glazing.

[0074] The groove 99c extends, in a cross-sectional view from said inner face 99d towards the outer space E and has a depth p 99 and a width l 99 . The depth p 99 of the groove 99c is between 50% and 90% of the thickness e 99 of the outer seal 99. The first and second projections 10a, 10b have a length L (visible on the [ Fig.5]) less than the thickness e 99 of the outer seal 99. Preferably, the length L is equal to at least 25% of the thickness e 99 , or even at least 50% of the thickness e99. The first and second projections 10a, 10b further have a thickness e 10 of between 0.8 and 1.1 times the width l 99 .

[0075] In the “lock closed” position, the first and second projections 10a, 10b are located in the groove 99c. Indeed, when the lock 10 is rotated 90° on itself, the first and second projections 10a, 10b enter the groove 99c. Thus, when the lock 10 is in the closed position, the outer seal 99 is flush, apart from a gap mentioned above, with respect to the outer face 21 of the outer pane 2 (outer face 31 of the outer glass sheet 3). The present invention therefore makes it possible to visually check, from the outside, the position of the lock 10.

[0076] As opposed to the closed position configuration visible on the [ Fig.3 ], the configuration of the glazing fixing system 1 in the open position is visible on the [ Fig.4]. When the lock 10 is in the open position, the lateral wing 12 is consequently positioned at 90° relative to its position when the lock 10 is in the closed position. The first projection 10a has at its end 10a' a contact surface and the second projection 10b has, for its part, at its end 10b' also a contact surface. Preferably, the ends 10a', 10b' have a rounded shape. Alternatively, the ends 10a', 10b' have a flat shape. 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 projections 10a, 10b thus press on the outer seal 99 so that its outer face 99a is out of line, in the direction of the outer space E, with respect to the outer face 21 of the outer pane 2 (outer face 31 of the outer glass sheet 3).

[0077] The present invention thus has the advantage of making it possible to simply check the position of the lock 10 of the external space E. For example, a controller, present on the platform next to which the wagon is positioned, can visually identify that the external seal 99 protrudes relative to the external face 21 of the external window 2 (external face 31 of the external glass sheet 3). He can, for example, report this problem to a team in charge of the maintenance of the wagon so that it can intervene to carry out a check of the position of the lock 10 and, possibly, move it to the closed position if necessary.

[0078] In the open position, the gap 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 gap is equal to, approximately, the length of the first and second projections 10a, 10b. In the present invention, it is desired that the outer seal 99 is sufficiently out of line with the outer face 31 of the outer glass sheet 3 so that this out of line is sufficiently visible and thus detects a problem relating to the position of the lock 10. In other words, the present invention is a foolproofing device. Indeed, it may be that during the assembly of the glazing 1, one or even several locks 10 were not inadvertently locked. Thanks to the invention, this oversight can be easily noticed.

[0079] The glazing frame structure further comprises an external structure 7' which extends on the external periphery of the outer pane 2 and / or on the external periphery of the inner pane 6, being further away (more centrifugal) than the peripheral edge 20, 60 respectively of the outer pane 2 and / or of the inner pane 6 starting from the center of the pane.

[0080] Here, the external structure 7' has in cross-section substantially the shape of an h, with a body 107 and two legs which extend more centrifugally from the body, the outer leg being shorter than the inner leg.

[0081] The external structure 7' is furthermore fixed to the internal sidewall 92 by gluing using a strip of glue 97, possibly supplemented by a joint or a strip of glue 108 located between the external foot of the external structure 7' and the external sidewall 91.

[0082] The external structure 7', visible in figures 4 And 5, is a lightweight external structure in the sense that it preferably extends only on the external periphery of the inner pane 6, being further than the peripheral edge 60 of the inner pane starting from the center of the pane (more centrifugal); it is also on the external periphery of the glazing cavity 8, being further than this glazing cavity starting from the center of the pane (more centrifugal), but it does not extend on the external periphery of the outer pane 2, being further than the peripheral edge 20 of the outer pane starting from the center of the pane.

[0083] Furthermore, the external structure 7' is a lightweight external structure in the sense that, preferably, it does not extend further towards the center of the internal glass 6 (more centripetal) than the spacer 71 so that the glazing clear is as large as possible.

[0084] The body 107 is preferably not directly in contact with the edge of the inner face 62 of the inner window 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 window 6.

[0085] Although not shown, the outer pane 2 could be as large as the inner pane 6, both in length along the X axis and in height along the Y axis.

[0086] Although not illustrated, the edge 20 of the outer pane 2 or the edge 50 of the inner glass sheet 5 may comprise a plastic centrifugal lip which extends, in the application space 95, towards the crosspiece 90.

[0087] The fixed state of the glazing is achieved by rotating the lock 10 90° on itself, around the axis of the fixing hole 93.

[0088] For proper fixing of the glazing, it is preferable to use several locks, especially several locks along each edge of the glazing. The interval between two adjacent locks is preferably between 100.0 and 400.0 mm, more preferably between 200.0 and 300.0 mm.

[0089] 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.

[0090] 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.

[0091] 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.

[0092] 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.

[0093] 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).

[0094] Furthermore 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.

[0095] 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.

[0096] 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.

[0097] 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.

[0098] 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.

[0099] 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.

[0100] In Figures 3 and 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.

[0101] On these Figures 3 and 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.

[0102] THE figures 5 And 7illustrate 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.

[0103] These figures show in particular that the lateral wing 12 of the lock can have an end 12a (opposite the body 11), at a point, having an angle α, in front view, as illustrated in the [ Fig.7 ], for example at 90°, in order to facilitate its passage into the attachment cavity 77 and come into contact, or almost into contact, with the bottom 78.

[0104] The lateral wing 12 further comprises a bevelled internal face, having an angle β, in top view, as illustrated in the [ Fig.6 ] and an angle θ, in front view, as illustrated in the [ Fig.7 ]. The shape of the lateral wing 12 makes it easier to block its rotation in both directions of rotation by contact against the wall of the attachment cavity 77.

[0105] The lateral wing 12 here penetrates into the hooking cavity 77 over the entire internal height of the rail 75, i.e. over a height of approximately 7 mm.

[0106] The lateral wing 12 of each lock is made in one piece with the body 11.

[0107] 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.

[0108] In particular, it is included in the present invention that the inner pane 6 can itself be laminated.
