The present invention relates to a system for securing a side window (1) of a vehicle to an outer window (9), particularly a train window. A lock (10) is secured to the window (9), the lock (10) having a side wing (12) extending within the hook cavity (77) and facing the edge of the middle surface (61) of the inner window glass (6) by a 90° rotation of the side wing (12).

Description

Technical Field

[0001] This invention relates to securing side windows (particularly train windows) of a transport vehicle to an outer window, typically made of metal, wherein the windows are fixed, multi-layered glass windows. This type of window is usually fixed to the train window in a vertical position. Background Technology

[0002] More specifically, this invention relates to the fixing of a lateral glass window having an outer surface facing an external space and an inner surface facing an internal space, wherein the outer surface of the glass window is visually continuous with the outer surface or outer side surface of the window over its entire perimeter. Visual continuity does not imply contact between the outer surface of the glass window and the outer surface of the window, as such contact is known to be avoided, especially when the window is made of metal; visual continuity means that, viewed in a vertical cross-section, the outer surface of the window and the outer surface of the glass window are continuous, and the distance between them is not zero.

[0003] The multi-pane windows of this type of transport vehicle typically include:

[0004] - Exterior window glass, which has an outer surface facing the external space, a middle surface opposite the outer surface, and an outer edge.

[0005] - Interior window glass, which has an inner surface facing the interior space, a middle surface opposite the inner surface, and an outer edge.

[0006] - and an internal structure located on the inner periphery of the outer window glass and the inner periphery of the inner window glass, respectively closer to the center than the outer periphery edges of the outer window glass and the inner window glass, and the internal structure holds the two window glass together so that the glass window provides a separation between the external space and the internal space, and the glass window cavity is located between the window glass.

[0007] In particular, international patent application WO 2019 / 228850 provides a multi-layered glass window for a transportation vehicle, which further includes a glass window frame structure having:

[0008] - This structure, being an internal structure, is located on the inner periphery of the outer window glass and the inner periphery of the inner window glass, respectively closer to the center than the outer periphery edges of the outer and inner window glass, and holds the two window panes together, such that the glass window provides a separation between the external space and the internal space, with the glass cavity located between the window panes.

[0009] - A part of the structure, which is an external structure, extends on the outer periphery of the outer window glass and / or the outer periphery of the inner window glass, respectively, and is farther from the center of the window glass than the outer periphery edges of the outer window glass and / or the inner window glass.

[0010] Then, this external structure of the glass window is mechanically and / or chemically fixed to the window to be closed.

[0011] Therefore, in this document, the internal structure includes spacers 71 and adhesive strips 76, both of which are located on the inner and outer peripheries of the glass window cavity 8, and the external structure includes adhesive strips 70 and frames 72.

[0012] Another solution for securing glass windows of transport vehicles can be seen in international patent application WO 2016 / 151256: the glass windows are simply glued together by an outer adhesive strip, which is shown in black in the figures of this document.

[0013] Existing fixing methods, such as gluing, mechanical fastening via a two-part frame, or clamping, are satisfactory, provided the glass is properly secured. However, these methods require access to the interior of the vehicle; such access can be difficult. This difficulty in access also makes replacing the glass during the vehicle's lifespan more challenging.

[0014] Furthermore, these solutions require complex dismantling, recycling, and sorting operations at the end of the vehicle's lifespan. Summary of the Invention

[0015] The purpose of this invention is to enable the creation of fixed multi-layered glass windows that can be attached externally to the vehicle body windows without requiring internal access for replacement.

[0016] Another objective is to allow such windows to be achieved without providing a large external rigid frame, and especially without metal or metal alloy or even elastomer or silicone frames (which would be tall) on the exterior of the glass window itself.

[0017] Therefore, the glass window is neither too expensive nor too heavy.

[0018] Furthermore, for the same window size, such external structural frames typically reduce the transparency of the glass window. Therefore, removing the external structural frame, or having the external structural frame but with its height reduced relative to the window glass, can increase the transparency of the glass window.

[0019] Finally, removing the external structural frame could allow for shallower windows and increase the usable space inside the vehicle.

[0020] Therefore, the present invention provides at least one, and preferably multiple, locks, and in particular multiple locks along each side of the glass window, for mechanically and effectively holding the multi-layered glass window from the periphery of the glass window cavity, while effectively protecting the lock or the locks so as to allow, preferably only from the outside, quick replacement of the glass window.

[0021] Therefore, at least one, and preferably multiple, latches are directly manufactured in the multilayer glass seal, and only in the seal, surrounding the entire window without any other mechanical fasteners, and the seal is provided to effectively protect the latches or these latches.

[0022] Surprisingly, we discovered that this method can be used to fix glass windows to outer windows, even for glass windows that are subjected to a lot of vibration due to their use as windows in transportation vehicles, especially trains.

[0023] The object of the invention, in its broadest sense, is a system for securing a side window (particularly a train window) of a transport vehicle to an outer window according to claim 1. The dependent claims have advantageous features. The window is a fixed, multi-layered glass window having an outer surface facing the external space and an inner surface facing the internal space, the outer surface of the window being visually continuous with the outer surface of the window over its entire perimeter, the window comprising:

[0024] - An exterior window slab having an outer surface facing the external space, a peripheral edge, and a middle surface opposite the outer surface. The exterior window slab is preferably laminated and therefore comprises at least one outer glass panel, an inner glass panel, and a plastic sheet between the outer and inner glass panels. Each panel of the exterior window slab has a peripheral edge.

[0025] - Interior window glass, which may optionally be laminated, has an inner surface facing the interior space, a middle surface opposite the inner surface, and an outer edge.

[0026] - An internal structure located on the inner periphery of the outer window glass and the inner periphery of the inner window glass, respectively at least partially closer to the center than the outer periphery edges of the outer and inner window glass, and the internal structure holding the two window glass together such that the window provides a separation between the external space and the internal space, with the window cavity located between the window glass.

[0027] The glass window according to the invention is characterized in that the internal structure includes a hook cavity having a concentric bottom and a centrifugal opening, the window including a lock secured to the window and positioned more centrifugally than the edge of the inner window glass. The lock has side wings extending within the hook cavity and facing the edge of the middle surface of the inner window glass by a 90° rotation of the side wings. Preferably, a hollow external seal is located in an application space between one side of the outer surface and the edge of the outer window glass or the edge of the outer glass panel. The external seal is located in the application space. For better sealing, the external seal preferably contacts the edge of the middle surface of the outer window glass or the edge of the middle surface of the outer glass panel.

[0028] The 90° rotation can be either the rotation of the side wing itself or a complete rotation of the entire lock itself.

[0029] To make the fixing system compact enough, each lock preferably has a single wing.

[0030] The 90° rotation of the lock itself is preferably achieved by rotating about the axis of the fixing hole (which is used to secure the lock). Thus, the lock is inserted into the application space located between the glass window and the adjacent window crossbar, with the wing oriented along the space, and then the lock rotates itself so that the wing passes into the hook cavity.

[0031] The lock operates by a snap-lock mechanism. It is this rotation that allows the glass window to be secured or attached to the window in one direction and detached from the window in the opposite direction.

[0032] The hook cavity is preferably formed by a partial groove located in the lock position or by an elongated track; each horizontal or vertical edge of the glass window preferably includes a single track; preferably, there are no tracks at the corners of the glass window.

[0033] The depth of the hook cavity, i.e., the distance between its inward bottom and its outward opening, is preferably between 2.0 and 15.0 mm, and more preferably between 3.0 and 10.0 mm. This distance is large yet small for good fixation of the glass window (i.e., good retention of the side wings in the hook cavity) so as not to unduly restrict the transparency of the glass window.

[0034] For a more compact system, the rotation of the lock itself can be eccentric, such that the wing moves away from the axis of the lock's fixing hole as it moves into the hook cavity.

[0035] Preferably, the internal structure does not protrude beyond the edge of the outer window glass or the edge of the inner window glass in the centrifugal direction; more preferably, the internal structure does not protrude beyond the edge of the outer window glass or the edge of the inner window glass in the centrifugal direction.

[0036] To facilitate the manufacture of the glass window, the inner glass panel may have the same dimensions (length, height) as the inner window glass.

[0037] The inner window glass itself may be laminated, but for ease of manufacturing, the constituent panels of the window glass preferably have the same dimensions (length, height).

[0038] In an alternative embodiment, the edge of the outer window glass or the edge of the outer glass panel is positioned along at least a portion of the length of the edge of the outer window glass or the outer glass panel, and preferably along the entire length of the edge of the outer window glass or the outer glass panel (i.e., along the entire periphery of the edge), centrifugally to protrude beyond the edge of the inner window glass.

[0039] The protrusion is between 5.0 and 30.0 mm, preferably between 8.0 and 20.0 mm. This contributes to the compactness of the fastener.

[0040] The key concept is the center of the reference glass pane, window pane, or window; it indicates centrifugal positioning, which is further away from the center than the reference position.

[0041] In another independent alternative embodiment, the edge of the plastic material panel and / or the edge of the inner glass panel is recessed inward from the edge of the inner window glass along at least a portion of the edge length of the plastic material panel and / or the inner glass panel, and preferably along the entire edge length of the plastic material panel and / or the inner glass panel (i.e., along the entire periphery of the edge).

[0042] The recess is preferably between 1.0 and 10.0 mm, more preferably between 2.0 and 8.0 mm. This contributes to the compactness of the fastener.

[0043] The concept of recess is to reference the center of a glass panel, window pane, or window; it indicates centripetal positioning, being closer to the center than the reference position.

[0044] The manufacture of laminated window glass (here, exterior window glass) whose constituent panels are not all of the same size (length, height) is more complex, but the advantages provided by the protrusions and / or the recesses are very important: they make it possible to improve the appearance of the window glass and the compactness of the fasteners.

[0045] The glass window preferably includes a spacer located between the inner glass panel and the inner window glass, the spacer being recessed from the edges of the inner glass panel and the inner window glass, and in cross-section, the spacer distance being further outward than the lateral continuity of the edge of the outer glass panel, the spacer distance being between 2.0 and 30.0 mm, preferably between 5.0 and 20.0 mm, or even between 6.0 and 15.0 mm.

[0046] A single glass plate, multiple glass plates, or even each glass plate may be reinforced through chemical or thermal treatment.

[0047] At least one or all of the plastic panels (if there are multiple) of the glass window may additionally have sound insulation capabilities.

[0048] In a particular embodiment, the edge of the outer window glass or the edge of the inner glass panel includes a centrifugal plastic lip. This lip helps to protect the lock located further inside.

[0049] The outer surface of the glass window is continuous with the appearance of the outer surface of the window over its entire perimeter, which means that the distance between them is not zero.

[0050] The distance between the outer surface of the glass window and the outer surface of the window is preferably between 5.0 and 25.0 mm, more preferably between 8.0 and 15.0 mm, which is very small. The body of the lock preferably has the same diameter or height as this distance, so that it can be inserted into the application space. The side wings of the lock preferably have the same width as this distance, so that they can be inserted into the application space.

[0051] Along this distance, preferably when the outer window glass is laminated, the external seal is present at the contact point between the edge of the outer surface of the window and the edge of the outer window glass or the edge of the outer glass panel. The height of the external seal is preferably between 5.0 and 30.0 mm, and more preferably between 8.0 and 20.0 mm. This small distance makes it possible to achieve an aesthetically pleasing visual appearance and contributes to achieving high transparency of the window glass.

[0052] When a centrifugal lip is present, it can provide a base for the external seal to prevent it from reaching the lock.

[0053] The glass window according to the invention preferably has no outwardly protruding elements beyond the outer surface of the glass window, which is also the outer surface of the exterior window glass, in order to reduce friction of the vehicle in the air. Then, the glass window can maintain visual continuity with the vehicle body window, with the outer surface of the glass window spaced apart from the outer surface of the exterior window.

[0054] When the external seal is continuously positioned between the outer surface of the glass window and the outer surface of the window, the glass window can be considered to be visually flush with the vehicle body window.

[0055] The internal seal is also preferably present at the contact point between the inner side of the window and the inner surface of the inner window glass.

[0056] Advantageously, the present invention thus makes it possible to manufacture fixed multi-layered glass windows, which may have an operable window, whose fasteners are accessible from the outside and have a smooth appearance, with no mechanical component located further out than the outer surface of the window glass.

[0057] Due to the fasteners according to the invention, the transparency of the glass window is relatively high; it is essentially defined by the position of the spacers.

[0058] The invention also relates to the use of at least one lock with side wings (preferably multiple locks, particularly multiple locks along each edge), each side wing being inserted into the hook cavity by rotating itself 90°, for securing the side windows of a transport vehicle (particularly train windows) to an outer window.

[0059] The window fixing system according to the invention is a system for fixing the side windows of a transport vehicle. It is a reliable system even though the window will be subjected to many vibrations due to its use as a side window in a transport vehicle. Attached Figure Description

[0071] In these accompanying drawings, the dimensions of the various components are not proportionally followed for ease of reading.

[0072] Figure 1 A left-side glass window 1 of a vehicle according to the invention is shown, which is vertically positioned and fixed to a vehicle body window 9.

[0073] This is especially true for the train's side windows.

[0074] Therefore, the glass window provides a vertical separation between the interior space I inside the train and the exterior space E outside the train. Figure 1 This is an external schematic diagram.

[0075] Therefore, the concepts of "external" and "internal" are considered in this paper with respect to the external space E (or toward the external space) and the internal space I (or toward the internal space), respectively.

[0076] Since this is a side window, it extends essentially along the axis commonly referred to as the "X-axis" of the vehicle, which is the central longitudinal axis of the forward movement of the vehicle equipped with the side window according to the invention (here on the left), and corresponds to... Figure 1 The X-axis is the vertical axis, the Y-axis is the vertical axis, and the Z-axis is the horizontal axis.

[0077] In the context of this document, the concepts of "centripetal" and "centrifugal" should be understood as follows: Figure 1 Consider the plane of the plate, or when the window is considered flat, consider the total plane of the window, according to the X and Y axes relative to the center of the window; the centripetal direction is towards this center, while the centrifugal direction is away from this center.

[0078] The glass window 1 is fixed. It is integrally formed and has no internal operable windows, as is known, for example, from International Patent Application WO 2016 / 042270; however, although not described in detail here, the present invention can be applied to such glass windows with operable windows.

[0079] The glass window 1 has an outer surface 101 facing the external space E and an inner surface 102 facing the internal space I.

[0080] The glass window 1 includes:

[0081] - The exterior window glass 2 has an outer surface 21 facing the external space E, a middle surface 22 opposite to the outer surface, and an outer edge 20.

[0082] - Interior window glass 6, having an inner surface 62 facing the interior space I, a middle surface 61 opposite the inner surface, and an outer edge 60, and

[0083] - Internal structure 7, which holds the two window panes together, such that the window provides separation between the external and internal spaces by providing a glass cavity 8 located between the window panes 2 and 6.

[0084] The internal structure 7 is called "internal" because it is located on the inner and outer peripheries of the outer window glass 2 and the inner window glass 6, and is at least partially (and preferably completely) more central (more centripetal) than the outer periphery edges 20 and 60 of the outer window glass 2 and the inner window glass 6, respectively; that is, the internal structure 7 does not protrude beyond the outer periphery edges 20 and 60 in the centrifugal direction.

[0085] Panels 3, 4, and 5 of glass window 1 and glass panes 2 and 6 are each integrally formed.

[0086] The interior window glass 6 is a single pane of glass with a thickness between 3.0 and 8.0 mm, for example, 5.0 mm.

[0087] The exterior window glass 2 is preferably laminated, and thus includes, starting from the external space E: at least one outer glass panel 3, an inner glass panel 5, and a plastic material panel 4 located between the outer glass panel 3 and the inner glass panel 5, each panel 3, 4, 5 of the exterior window glass 2 having peripheral edges 30, 40, 50.

[0088] The outer glass panel 3 has an outer surface 31 facing the external space E, a sandwich surface 32 facing the sandwich plastic material panel 4, and an outer edge 30 located between the two surfaces.

[0089] The inner glass panel 5 has a sandwich surface 51 facing the plastic material panel 4, an inner surface 52 facing the glass window cavity 8, and an outer edge 50 located between the two surfaces.

[0090] The plastic material plate 4 has an outer clamping layer 41 oriented toward the clamping layer 32 and in contact with the clamping layer 32, and an inner clamping layer 42 oriented toward the clamping layer 51 and in contact with the clamping layer 51. The outer edge 40 is located between the two clamping layers 41 and 42.

[0091] The outer glass panel 3 is, for example, a glass panel with a thickness between 0.5 and 8.0 mm, such as 6.0 mm.

[0092] The sandwich plastic material panel 4 is, for example, a polyvinyl butyral (PVB) panel with a thickness between 0.50 and 1.50 mm, such as 0.76 mm. This plastic material panel 4 preferably has the same length and height dimensions as the outer glass panel 3.

[0093] The inner glass plate 5 is a glass plate with a thickness between 0.5 and 8.0 mm, for example, 5.0 mm.

[0094] Here, the glass window 1 therefore has a total thickness t' of 26.76 mm.

[0095] The glass window 1 is a fixed glass window, and in this sense, the internal structure 7 is also designed to allow the glass window 1 to be fixed to the structure 9 of the means of transport (here, the train) without the possibility of movement relative to the structure 9.

[0096] The glass window 1 is a multi-pane glass window because it includes multiple window panes 2 and 6 and a glass window cavity 8 located between two window panes 2 and 6, which is filled with air or gas, preferably neutral, such as argon or krypton; the cavity participates in the thermal insulation provided by the glass window 1.

[0097] Therefore, the internal structure 7 allows the two window panes 20 and 60 to remain separated from each other, with a constant distance between them, which is 10.0 mm.

[0098] The internal structure 7 includes a hook cavity 77 having a centripetal bottom 78 and a centrifugal opening 79.

[0099] The hook cavity 77 preferably has a depth p, which is the distance between its inward bottom 78 and its centrifugal opening 79, between 2.0 and 15.0 mm, preferably between 3.0 and 10.0 mm, and here 7.0 mm.

[0100] Window 9 includes an outer side 91 oriented vertically and facing the outside space, and an inner side 92 oriented vertically and facing the outside space. These two sides are connected by a crossbar 90, which is horizontal along its horizontal edge and vertical along its vertical edge. Although not shown, the crossbar may also be inclined or cross-shaped. This connection forms an application space 95 in which the glass window is positioned and then secured during its installation in the window to be closed.

[0101] Therefore, window 9 is on the periphery: it surrounds the entire glass window 1.

[0102] Window 9 includes a lock 10, which is secured or attached to the window and positioned more centrifugally than the edge 60 of the inner window glass 6. The lock 10 has side wings 12 extending into the hook cavity 77 and, by rotating the side wings 12 90°, aligning them with the edge of the center surface 61 of the inner window glass 6 to hold the glass in place. This lock, or each lock, can secure the glass and remove it when it needs to be replaced with another type of glass, while keeping (one or more) locks directly or indirectly secured to the window.

[0103] like Figures 2 to 5 More specifically, the internal structure 7 includes means for creating and maintaining the presence of the glass window cavity 8 and for holding the glass window in place, and the internal structure 7 includes:

[0104] - Internal spacer 71, located between the inner glass panel 5 and the inner window glass 6.

[0105] - The internal adhesive strip 76, located between the inner glass panel 5 and the inner window glass 6, is further outward than the spacer 71.

[0106] - A slender U-shaped internal track 75 extends between the edges of the intermediate surface 22 and the intermediate surface 61, thus having an opening facing the bottom of the glass window cavity 8 and an opening facing the opposite direction to form a hook-and-hook cavity 77, and

[0107] - Optional internal adhesive strip for bonding track 75 to the middle surface 22 of the outer window glass 2 on one hand and to the middle surface 61 of the inner window glass 6 on the other hand.

[0108] Preferably, the track 75 and the hook cavity 77 do not directly contact the edges of the intermediate surface 22 and the surface 61. The track 75 is preferably embedded in the adhesive strip.

[0109] Although not shown, instead of the elongated track present along each edge of the glass window, the hook cavity formed by the local groove at each lock position can be provided; thus, between two local grooves, the adhesive strip 76 fills the entire space between the spacer 71 and the ribs between the edges 20, 60 and the corresponding intermediate surfaces 22, 61.

[0110] The spacers 71 are recessed from the edges 50 and 60 of the inner glass panel 5 and the inner window glass 6 toward the center of the window, and are spaced apart when viewed in cross-section, with a spacing distance e, which is further outward than the lateral continuity of the edge 60 of the inner window glass 6. This spacing distance e is preferably between 10.0 and 50.0 mm, even 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 window transparency.

[0111] The spacer 71 may be made of, for example, plastic and / or metal and / or metal alloy; it keeps the two panes of glass 2, 6 at a constant distance from each other and maintains the glass cavity 8.

[0112] The spacer 71 is held in place against the middle surface 61 of the inner window glass 6 and against the inner surface 52 of the inner glass panel 5 by adhesive strip 76.

[0113] The glass window 1 does not include a frame, especially not a rigid metal frame, which holds the window glass 2 and 6 respectively by the outer surface 21 and the inner surface 62.

[0114] Due to the presence of the internal sealing strip 70, the inner surface 92 preferably does not directly contact the edge of the inner surface 62 of the inner window glass 6; the internal sealing strip 70 is preferably integrally formed and also preferably does not contact the edge 60 of the inner window glass 6. It is preferably prefabricated and then bonded to the edge of the inner surface 62.

[0115] The adhesive strip 76, alone or together with the adhesive strip, preferably fills all remaining space except for the space created by the hook cavity 77, and in the lateral direction fills the space between the middle surface 61 of the inner window glass 6 and the middle surface 22 of the outer window glass 2, and preferably fills all height space between the spacer 71 and the ribs between the edge 60 and the middle surface 61.

[0116] The adhesive strip may comprise or be a polyurethane or silicone or polymer MS (i.e., silane-modified polyether) or polysulfide-based adhesive strip, such that it is chemically bonded at least to the inner window glass, and preferably chemically bonded to both window glass panes on either side of the glass cavity.

[0117] The adhesive strip may include a metal profile that is laterally bonded to each side of the glass cavity, or partially or completely embedded in the adhesive strip.

[0118] The adhesive strip may include cables, particularly metal cables, which are laterally bonded to at least one side of the glass cavity so that the glass can be more easily broken by pulling the cable.

[0119] The outer side 91 is preferably located in the appearance continuity of the outer surface 31 of the outer glass plate 3 (i.e., it is vertical here), that is, in 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.

[0120] Preferably, the hollow outer seal 99 is located in the application space 95 between the following two (preferably having contact):

[0121] - On the one hand, the edge of the outer side 91 and the crossbeam 90

[0122] - On the other hand, the edge 20 of the outer window glass 2 (in the case of a single-pane outer window glass), or on the other hand, the edge 30 of the outer glass panel 3 as described herein.

[0123] - Preferably, it contacts the edge of the middle surface 22 of the outer window glass 2 (in the case of a single-pane outer window glass), or as described herein, contacts the edge of the middle surface 32 of the outer glass panel 3.

[0124] To achieve the latter type of contact, the outer seal 99 preferably has a supporting lip 109.

[0125] The external seal 98 is flush with the outer surface 31 of the outer glass panel and does not extend further outward than the outer surface 31. Preferably, it surrounds the entire glass window and is integrally formed.

[0126] The external seal 99 preferably has a height h between 5.0 and 30.0 mm, preferably between 8.0 and 20.0 mm, for example 18.0 mm.

[0127] The external seal 99 preferably does not fill the entire space between the outer side 91 and the edge 20 of the outer window glass 2, so that it can be easily removed to access the head 105.

[0128] It has been confirmed that, based on Figure 1 In the example shown, sufficient thermal insulation is achieved when the glass window cavity 8 is integrally formed, filled with argon gas, and has a uniform thickness. Therefore, the distance between the outer surface 101 and the inner surface 102 is constant, here 28.76 mm.

[0129] The fastener according to the invention preferably includes a plurality of side wings 12 that extend in a completely centripetal direction, that is, when their lock is closed, for the horizontally extending side wings, they extend toward the vertical central axis of the glass window, and when their lock is closed, for the vertically extending side wings, they extend toward the horizontal central axis of the glass window.

[0130] It has been confirmed that when glass window 1 is subjected to conditions similar to those it experiences when integrated into a train traveling at 160 km / h, based on Figure 1 The example obtained appropriate mechanical strength.

[0131] exist Figure 2 and Figure 3 In the first embodiment shown, the frame structure of the glass window includes only a portion of the internal structure 7, and this portion is located on the inner periphery of the outer window glass 2 and the inner periphery of the inner window glass 6, closer to the center (more centripetal) than the outer periphery edges 20 and 60 of the outer window glass 2 and the inner window glass 6, respectively, and this portion holds the two window glass together so that the glass window provides a separation between the external space E and the internal space I, and the glass window cavity 8 is located between the window glass 2 and 6; there is no part of the external structure.

[0132] In the first embodiment, the side wing 12 of the lock 10 is inserted into the hook cavity 77 by a simple and direct 90° rotation of the lock itself.

[0133] exist Figure 2 and Figure 3 In the first embodiment shown, when the glass window is fixed to the window, the inner side 92 extends in a centripetal direction, is more centripetal than the edge 60 of the inner window glass 6, and has a fixing hole 93 that is more centrifugal than the edge 60 of the inner window glass 6; the fixing hole 93 has an axis A9 parallel to the edge 60 of the inner window glass 6; that is, a horizontal axis.

[0134] In this first embodiment, the lock 10 is directly secured to the inner surface 92 by a fixing device 104 (e.g., a bolt with a head 105) and secured on the other side of the inner surface 92 by a nut 106. The bolt passes through a fixing hole 93, and the head 105 is thus located in the application space 95. The lock 10 has a horizontally oriented hollow cylindrical body 11, the fixing device 104 freely passing through the interior of the body 11, and a side wing 12 (and preferably only one side wing) extending from the body 11 toward the center of the glass window in the fixed state. The side wing 12 is within the hook cavity 77 and is opposite to the edge of the middle surface 61 of the inner window glass 6.

[0135] Due to the presence of the internal sealing strip 70, the inner surface 92 preferably does not directly contact the edge of the inner surface 62 of the inner window glass 6; the internal sealing strip 70 is preferably integrally formed and also preferably does not contact the edge 60 of the inner window glass 6. It is preferably prefabricated and then bonded to the edge of the inner surface 62.

[0136] Figure 2 The fastener of the glass window 1 shown according to the invention is particularly compact in terms of its thickness, because when the thickness of the glass window and the sides is included, the total thickness t of the fastener from the outer surface 101, 21 to the inner surface 92 is 34.76 mm.

[0137] exist Figure 4 In the second embodiment shown, the frame structure of the glass window includes:

[0138] - On one hand, a portion of the internal structure 7, as described for the first variant, and located on the inner periphery of the outer window glass 2 and the inner periphery of the inner window glass 6, is closer to the center (more centripetal) than the outer periphery edges 20 and 60 of the outer and inner window glass, respectively, and this portion holds the two window glass pieces together, such that the window provides a separation between the external space and the internal space, and the window cavity 8 is located between the window glass pieces 2 and 6.

[0139] - On the other hand, the external structure 7' extends from the outer periphery of the outer window glass 2 and / or the outer periphery of the inner window glass 6, starting from the center of the window glass and being further (more centrifugal) than the outer periphery edges 20 and 60 of the outer window glass 2 and / or the inner window glass 6, respectively.

[0140] Here, the outer structure 7' has a substantially h-shaped cross-section, with a main body 107 and two legs extending more centrifugally from the main body, the outer legs being shorter than the inner legs.

[0141] In this second embodiment, the lock 10 is indirectly fixed to the inner surface 92: the lock 10 is directly fixed to the outer structure 7' by a fixing device 104 (e.g., a bolt with a head 105) and by a nut 106. The bolt passes through a fixing hole 93 located in the body 107, and the head 105 is thus located in the application space 95.

[0142] The lock 10 has a horizontally oriented hollow cylindrical body 11, a fixing device 104 freely passing through the interior of the body 11, and a side wing 12 (and preferably only one side wing) extending from the body 11 toward the center of the glass window in the fixed state. The side wing 12 is in the hook cavity 77 and is opposite to the edge of the middle surface 61 of the inner window glass 6.

[0143] In addition, in this second embodiment, the outer structure 7' is bonded to the inner side 92 using tape 97, and optionally supplemented by a seal or tape 108 located between the outer foot and the outer side 91 of the outer structure 7'.

[0144] Figure 4 The visible external structure 7' is a lightweight external structure that preferably extends only on the outer periphery of the inner window glass 6, starting from the center of the window glass further away (more centrifugal) than the outer periphery 60 of the inner window glass; it is also located on the outer periphery of the glass window cavity 8, starting from the center of the window glass further away (more centrifugal) than the glass window cavity, but it does not extend on the outer periphery of the outer window glass 2, starting from the center of the window glass further away than the outer periphery 20 of the outer window glass.

[0145] Furthermore, the outer structure 7' is a lightweight outer structure, preferably one that does not extend further (more centripetally) toward the center of the inner window glass 6 than the spacer 71, so that the transparency of the window is as great as possible.

[0146] Due to the presence of the internal sealing strip 70, the main body 107 preferably does not directly contact the edge of the inner surface 62 of the inner window glass 6; the internal sealing strip 70 is preferably integrally formed, and more preferably, does not contact the edge 60 of the inner window glass 6.

[0147] In the following text Figure 4 In the case of the fasteners, when the thickness of the glass window and the sides is included, the total thickness t from the outer surface 101, 21 to the inner surface 92 is also 34.76 mm.

[0148] exist Figure 5 In the third embodiment shown, the glass window 1 has the same structure as the first and second embodiments, and its fixing is similar to that of the second embodiment, having an outer structure 7' extending on the outer periphery of the inner window glass 6, which is further away (more centrifugal) than the outer periphery 60.

[0149] In this third embodiment, the outer seal 99 does not include the supporting lip 109. It is attached to the head 105 by a screw 119 extending into the outer space E.

[0150] Although not shown, the outer window glass 2 is the same size as the inner window glass 6 in both length along the X-axis and height along the Y-axis.

[0151] Although not shown, the edge 20 of the outer window glass 2 or the edge 50 of the inner glass panel 5 may include a centrifugal plastic lip 73 that extends toward the crossbar 90 into the application space 95.

[0152] In all three embodiments, the fixed state of the glass window is achieved by rotating the lock 10 90° around the axis of the fixing hole 93.

[0153] To properly secure the glass window, it is preferable to use multiple locks, particularly along each edge of the glass window. The spacing i between two adjacent locks is preferably between 100.0 and 400.0 mm, more preferably between 200.0 and 300.0 mm.

[0154] In all three embodiments, the outer window glass 2 is larger than the inner window glass 6 in both length along the X-axis and height along the Y-axis, allowing a portion of the lock 10 to be concealed behind the outer edge of the outer window glass 2. More specifically, the outer glass panel 3 is larger than the inner window glass 6 in both length along the X-axis and height along the Y-axis. This allows a portion of the lock 10 to be concealed behind the outer edge of the outer glass panel.

[0155] Therefore, the edge 30 of the outer glass panel 3 extends centrifugally from the edge 60 of the inner window glass 6 along at least a portion of the length of the edge 30 of the outer glass panel 3, and preferably along the entire length of the edge 30 of the outer glass panel 3 (i.e., along the entire periphery of the edge 30); if the outer window glass 2 is integral (and not laminated), the edge 20 of the outer window glass may protrude.

[0156] Therefore, when viewed from the front, the protrusion d preferably surrounds the entire outer window glass 2: the edge 30 of the outer glass panel 3 extends further than the edge 60 of the inner window glass 6 in a direction opposite to the center of the outer window glass 2. This protrusion d is preferably constant along the longitudinal or transverse edge under consideration; it is preferably the same along each longitudinal and transverse edge of the outer window glass 2.

[0157] The protrusion d is preferably between 5.0 and 30.0 mm, more preferably between 8.0 and 20.0 mm; here it is 13.0 mm.

[0158] The protrusion d can be hidden from view of the external space E by an enamel layer located around the outer surface 21 of the outer window glass (or around the outer surface 31 of the outer glass panel when the outer window glass is laminated).

[0159] In these three embodiments, apart from the aforementioned protrusion d and independent of the aforementioned protrusion d, the inner glass plate 5 is smaller than the inner window glass 6 in both length along the X-axis and height along the Y-axis.

[0160] When the laminated outer window glass 2 is viewed in cross-section, the edge 50 of the inner glass panel 5 is recessed inward from the edge 30 of the outer window glass 3 along at least a portion of the length of the edge 50 of the inner glass panel 5, preferably along the entire length of the edge 50 of the inner glass panel 5.

[0161] Therefore, when viewed from the front, the recess r preferably surrounds the entire outer window glass 2: the edge 50 of the inner glass panel 5 is more oriented toward the center of the outer window glass 2 than the edge 60 of the inner window glass 6. This recess r is preferably constant along the considered longitudinal or transverse edge; it is preferably the same along each longitudinal and transverse edge of the outer window glass 2.

[0162] The recess r is preferably between 1.0 and 10.0 mm, more preferably between 2.0 and 8.0 mm; here it is 5.0 mm.

[0163] The recess r can be hidden from view of the external space E by an enamel layer located around the outer surface 21 of the outer window glass (or around the outer surface 31 of the outer glass panel when the outer window glass is laminated).

[0164] exist Figures 2 to 5 In the middle, the opening of the track 75 and the opening of the hook cavity 77 exist in the extension of the edge 60 of the inner window glass only in the centrifugal direction.

[0165] exist Figures 2 to 5 In this process, the adhesive strip 76 preferably fills the entire transverse space between the inner surface 62 of the inner window glass 6 and the surface 52 of the inner glass panel 5. Furthermore, it extends in contact with the edge 50 of the inner glass panel 5, the edge 40 of the plastic material panel 4, and the surface 32 of the outer glass panel 3, but does not extend to the edge 30.

[0166] exist Figures 2 to 5 In this process, the adhesive strip 76 preferably fills the entire height space between the spacer 71 and the ribs between the edge 60 and the surface 61.

[0167] Figure 6 and Figure 7 The central rotary lock 10 is shown: the main body 11 of the lock is a hollow cylinder, which is pierced by a cylindrical tube coaxial with the axis of the main cylinder for the passage of the fixing device 104.

[0168] These figures specifically show that the lock's wing 12 may have a ramp 13, such as a 45° ramp, to facilitate its entry into the hook cavity 77 and contact or nearly contact with the bottom 78.

[0169] Here, the wing has a width l12 of 13.0 mm. The length between the axis of the lock and the end of the wing 12 is approximately 26 mm.

[0170] Here, wing 12 inserts into hook cavity 77 at the entire internal height of track 75, that is, at a height of approximately 7 mm.

[0171] The lock 10 also includes a circular central cavity 14 through which an accessory of a complementary shape passes, the accessory being part of the external seal 99 to participate in holding the external seal 99 in place.

[0172] In another embodiment, the side wing 12 of the lock 10 is inserted into the hook cavity 77 by a 90° eccentric rotation of the lock itself.

[0173] The rotation is eccentric, such that as the wing 12 enters the hook cavity, the wing moves away from the axis A9 of the fixing hole 93.

[0174] This eccentric rotation can be achieved by providing an elliptical washer 94 between the lock body 11 and the inner side 92 on the one hand, and by providing opposing cylindrical grooves in the wall of the body 11 on the other hand.

[0175] Figure 8 and Figure 9 An eccentric rotary lock 10 is shown, which is the same as the previous lock except that, for the passage of the fixing device 104, the body 11 is a hollow cylinder pierced by a cylindrical tube that is not on the same axis as the body cylinder: the axis of the cylindrical tube is laterally offset relative to the longitudinal direction of the wing 12.

[0176] exist Figures 2 to 5 In the three embodiment variations of the lock shown, the side wings 12 of each lock are integrally formed with the body 11.

[0177] Figures 10 to 12 A specific embodiment of the lock is shown, wherein the wing 12 is separate from (or distinct from) the body 11.

[0178] The wing 12 also preferably has an elliptical pre-reserved portion 17 for accommodating the head 105 of the fixing device.

[0179] Figure 10 The wing 12 is shown before it is positioned in the hook cavity. The wing 12 is entirely located in the application space 95.

[0180] Figure 11 The wing 12 is shown in the hook cavity after being rotated 90°.

[0181] Figure 12 Is with Figure 11 The same diagram, but it's a perspective view.

[0182] like Figure 10 As shown, this specific embodiment allows the wing 12 to be held in an extended position along the application space 95 for the time required to insert or remove the glass window 1 from the window 9 (e.g., if it is broken during use of the vehicle).

[0183] In this specific embodiment, only the side wing 12 is movable by rotating 90°; the rest of the lock (particularly the body 11) is stationary.

[0184] The invention has been described foregoing by way of example. It should be understood that those skilled in the art will be able to implement various alternative embodiments of the invention without departing from the scope of the claims.

[0185] In particular, the inner window glass 6 in this invention may itself be laminated.
