Description

GLAZING WITH A MONOBLOCK GLAZING DOOR AND METHOD FOR MANUFACTURING SAID GLAZING

[0001] The invention relates to a glazing, particularly for vehicles, movable in translation, comprising on the one hand a glass, and on the other hand at least one glass holder, called a "holder" in English.

[0002] The invention also relates to a vehicle comprising at least one such glazing.

[0003] The invention also relates to a method of manufacturing said glazing.

[0004] The invention relates to the field of glazing comprising a pane of glass and at least one pane of glass to allow said pane to be moved by translation.

[0005] The invention relates in particular to the field of vehicle glazing, especially for motor vehicles.

[0006] The invention is described with regard to a vehicle glazing application comprising a window, in particular a laminated window comprising an outer sheet of glass, an inner sheet of glass and an interlayer sheet of adhesive material located between said two sheets of glass, said window having an outer face intended to be oriented towards an outer space, an edge and an inner face intended to be oriented towards an inner space.

[0007] Such glazing typically includes at least one glass holder, which supports the glass and allows it to be operated. Several types of glass holders are currently available for different glazing options, with or without frames. These holders can be made of plastic (particularly fiberglass-reinforced plastic) or metal (aluminum) and connect the glass to the window regulator. A holder consists of two main parts: a U-shaped bracket that is bonded to the glass with standard polyurethane adhesive, and a tail designed to allow the glass to be attached to the regulator.

[0008] Manufacturing constraints arise, both for the manufacture of this glass holder and for its assembly with the glass.

[0009] The tooling for manufacturing a plastic window holder is not a simple mold and includes one or more drawers for demolding complex shapes (U-shaped), which makes manufacturing expensive, both in tooling cost and operating cost.

[0010] The management of the glue between the glass carrier and the glazing is not controlled, neither by its application, nor by its distribution after assembly (fitting the glass causes the glue to creep without much control).

[0011] US patent 2005 / 07077 describes a glass carrier in two parts joined by a hinge. Each part consists of a section of tubing and a lug; one section of tubing is designed to slide into the other, and the final position is secured by the engagement of the lugs. This glass carrier is not sufficiently reliable because when an assembler, particularly on a high-speed assembly line, overtightens the bolt, it causes the lugs to disengage.

[0012] Document DE 3535719 describes a plate and counter-washer glass holder system with a spiral outer surface and three lugs, which is screwed into the inside of a partially tubular, three-part element attached to the plate. This system is intended to compensate for tolerances but is not sufficiently reliable because, in the absence of a counter-plate, all the stresses are transferred to the plate.

[0013] US patent 2021078708 describes a window carrier system with two flanges connected by a hinge, forming a single unit. These two flanges can be folded together around the hinge, and this folded position is held in place by a hollow central clip. The hole in this clip is used to attach the window carrier to the window drive system. This configuration is not sufficiently reliable because, during window manufacturing or vehicle operation, the attachment of the window carrier to the window drive system can cause the hollow central clip to unclip or break.

[0014] The objective of the present invention is to remedy these drawbacks by proposing a glazing comprising at least one monobloc glass carrier.

[0015] In particular, the invention focuses on designing a glass holder made in a single piece, using a simple injection molding process (two-part mold), and allowing for improved adhesive management (control of application and distribution after assembly). This glass holder advantageously opens along the midline of its cross-section, in two parts connected by plastic hinges.

[0016] To achieve this objective, the invention proposes a vehicle glazing according to claim 1.This vehicle glazing is movable in translation and comprises on the one hand a pane of glass, preferably laminated, said pane having an outer face intended to be oriented towards an outside space, an edge, and an inner face intended to be oriented towards an inside space, said glazing comprising on the other hand at least one glass holder, having an opening arranged for the passage of a shaft for driving said glass, said glass holder comprising an inner flange positionable opposite said inner face of said glass, and an outer flange positionable opposite said outer face of said glass, said inner flange and said outer flange comprising respectively an inner bearing surface and an outer bearing surface arranged to bear against each other in a position for holding said glass.

[0017] According to the invention, said inner flange and said outer flange are connected to each other by at least one hinge with which they form a single unit, and are superimposed on each other to form a clamp gripping said glass in a holding position in which said glass holder is folded around a folding axis defined by said at least one hinge, and in which holding position said inner flange and said outer flange are held pushed towards each other by a locking cooperation between on the one hand locking means comprising said inner flange, and on the other hand complementary locking means comprising said outer flange.

[0018] The locking means and supplementary locking means are located on one lateral edge of the glass door, and preferably on two opposite lateral edges of the glass door; preferably, a lower edge of the glass door, the one containing the hinge, and an upper edge of the glass door do not have locking means or supplementary locking means. Thus, the holding position is both easier to achieve and more reliable (better hold at the time of locking and better hold over time); this is even better when both lateral edges are each held by interlocking the locking means of the inner flange with supplementary locking means of the outer flange.

[0019] Thanks to the invention, the handling of the window holder is easy, and the relative positioning of the inner flange and the outer flange is ensured in a reliable and precise manner, both at the time of assembly and throughout the entire time of use of the vehicle.

[0020] Preferably, said openings arranged for the passage of a shaft for driving the window do not include additional locking and unlocking means.

[0021] Advantageously, said inner flange and said outer flange respectively comprise at least one flat inner gluing surface carried by an inner arm and at least one flat outer gluing surface carried by an outer arm.

[0022] The gluing process, prior to the installation and gluing of the glass, is thus both easy and precise.

[0023] Advantageously, said glazing comprises an inner layer of adhesive between said at least one inner bonding surface and said glass, and an outer layer of adhesive between said at least one outer bonding surface and said glass.

[0024] This configuration, combined with controlled tightening thanks to the combination of locking means and additional locking means, makes it possible to control the creep of the glue and the regularity of the glue layers after the glass is glued to the glass holder.

[0025] Advantageously, said locking means and said complementary locking means are clipping means comprising an elastic lug arranged to cooperate with a notch, or vice versa, and which are arranged to press said inner arm and said outer arm against said glass in said holding position.

[0026] These simple methods can be achieved by injection or molding, and are easy to implement; their combination guarantees good glue flow and good glass retention.

[0027] Advantageously, said at least one glass holder includes at least one elastically deformable area at the level of said locking means and / or said supplementary locking means, and an elastically or plastically deformable area at the level of each said hinge.

[0028] This arrangement allows for possible dismantling.

[0029] Advantageously, said inner flange and said outer flange each comprise, at the closest point to said at least one hinge, a solid part comprising respectively said inner bearing surface and said outer bearing surface which are flat surfaces, and comprising respectively an inner orifice and an outer orifice superimposable in said holding position, in which holding position said solid parts together form an operating tail of said glass carrier.

[0030] This configuration ensures the obtaining of a rigid tail, capable of cooperating with a drive mechanism in translation of the glass.

[0031] Advantageously, said inner flange and / or said outer flange comprises, at the level of said inner arm or respectively said outer arm, and connected to said at least one inner gluing surface or respectively to said at least one outer gluing surface, a housing for receiving, recessed or in contact with said glass, at least one component and / or an electrical cable and / or a cutting wire.

[0032] Thus it is possible to position and integrate accessories such as LED lighting strips, defrosting equipment, or other.

[0033] Advantageously, said inner flange and / or said outer flange includes at least one bracket for the passage and retention of at least one said electrical cable.

[0034] Such a cable guide ensures that it remains in position, without risk of obstructing the movement of the window.

[0035] Advantageously, said housing is delimited, on the side furthest from said glass in said holding position, by a surface coplanar to said at least one inner bonding surface or respectively to said at least one outer bonding surface.

[0036] This configuration allows for the possible contact of the component with the edge of the glass.

[0037] The invention also relates to a vehicle comprising at least one such glazing.

[0038] The invention further relates to a method for manufacturing such glazing according to claim 11. This glazing is translationally movable and comprises, on the one hand, a pane of glass, preferably laminated, said pane having an outer face intended to be oriented towards an exterior space, an edge, and an inner face intended to be oriented towards an interior space, said glazing comprising, on the other hand, at least one glass holder, having an opening arranged for the passage of a shaft for driving said glass, said glass holder comprising an inner flange positionable opposite said inner face of said glass, and an outer flange positionable opposite said outer face of said glass,said inner flange and said outer flange respectively comprising an inner bearing surface and an outer bearing surface arranged to be held pushed towards each other by the cooperation between, on the one hand, locking means comprising said inner flange, and on the other hand, complementary locking means comprising said outer flange, in a holding position in which said inner flange and said outer flange enclose said glass, in which process said glass holder is made by flat fabrication of a substantially flat blank by means of an injection or forming mold in two lower and upper parts, said lower part and said upper part comprising only flat or straight surfaces or simple undercuts without undercuts,said blank comprising an inner flange and an outer flange connected to each other by at least one hinge, with which they form a single unit, said at least one hinge defining a bending axis, said blank being placed in an open position upon exiting said mold, in which open position said inner flange and said outer flange are substantially aligned with each other. Said lower part and said upper part thus preferably comprise, respectively, at least one flat inner gluing surface and at least one flat outer gluing surface, facing the same direction.

[0039] Manufacturing a one-piece glass carrier is economical, and installation is simplified, particularly by directly aligning the inner and outer flanges relative to each other. Having a flat component facilitates gluing before the glass is positioned and gluing the glass carrier during the folding process on either side of the glass.

[0040] Advantageously, after the removal of said mold and said placement in the open position, in a first preparation operation of said glass, said glass is cleaned and / or receives a bonding primer on its surfaces intended to come into contact with said glass holder; in a second gluing operation of said glass holder, said at least one flat inner gluing surface and said at least one flat outer gluing surface are cleaned and glued with an adhesive; in a third initial gluing operation, said inner flange of said glass holder is positioned resting on a support, and said inner face of said glass is glued with said at least one inner gluing surface with controlled creep of said adhesive to form an inner adhesive layer between said at least one inner gluing surface and said glass.In a fourth folding and second gluing operation, said blank is folded around said folding axis, and said inner flange and said outer flange are clipped together by the cooperation between said locking means and said complementary locking means, and said outer face of said glass is glued to said at least one outer gluing surface with controlled creep of said glue to form an outer glue layer between said at least one outer gluing surface and said glass, and in a fifth polymerization operation during which said inner glue layer and said outer glue layer are polymerized.

[0041] The sequence thus includes flat operations, during which the cleaning and gluing of the glazing components are easy, and an exact placement of the glass carrier on the glass during its folding, as well as a controlled compression of the glue thanks to the cooperation of the locking means with the complementary locking means, which cooperation also ensures their correct relative geometric positioning.

[0042] The invention will be further detailed by describing non-limiting embodiments, and based on the accompanying figures illustrating variants of the invention, in which: - a cross-sectional schematic illustration shows a glass holder suitable for glazing according to the invention, as it exits an injection or forming operation between a lower and an upper part of a mold limited to these two parts and without a drawer; these two parts are of simple shapes, without undercut surfaces; the glass holder comprises an inner flange on the right side of the figure, and an outer flange on the left side of the figure, joined by at least one hinge element around a folding axis; - a perspective schematic illustration, in its flat state, as it exits the mold, shows the glass holder, which comprises, without limitation, three hinge elements defining a folding axis. The inner and outer flanges comprise,As close as possible to the hinge, there are respectively an inner and an outer bearing surface arranged to bear against each other in a position that holds the glass when the glass carrier is folded around the folding axis. Each of these inner and outer bearing surfaces has an opening for the passage of a shaft of a glass-lifting mechanism for the translational movement of the glass. The inner and outer flanges each also have, as far as possible from the hinge and set back from these inner and outer bearing surfaces, a bonding surface arranged to receive an adequate amount of adhesive for bonding the glass. The outer flange has two locking lugs arranged to cooperate in a complementary manner with two notches formed in the inner flange; - schematically illustrated, in a cross-section similar to,The same glass carrier after a gluing operation where these inner and outer gluing surfaces are cleaned and glued with adhesive; - schematically illustrates, similarly to, glazing with the same glass carrier, after a first gluing operation, where the inner flange rests on a support, and the inner face of the glass is glued to the inner gluing surface; - schematically illustrates, similarly to, the same glazing after a folding operation of the glass carrier around the folding axis defined by the hinges, and a second gluing where the outer face of the glass is glued to the outer gluing surface, with the inner flange clipped to the outer flange in a holding position; - schematically illustrates, similarly to, a variant of the glass carrier, having, on the inner flange, a clip for the passage and retention of an electrical cable.which here powers a luminous component comprising an LED module, bonded to the inner bonding surface, between the inner flange and the glass; - schematically illustrates, in a cross-section similar to, a glazing unit comprising the glass holder in the holding position; - schematically illustrates, similarly to, a glazing unit with another variant of the glass holder, in its holding position, enclosing, on the one hand between the inner flange and the glass and an inner layer of adhesive, and on the other hand between the outer flange and the glass and an outer layer of adhesive, a cutting wire allowing possible disassembly of the glass holder from the glass, by cutting the adhesive layer; - schematically illustrates a vehicle, in particular a motor vehicle, comprising glazing according to the invention; and - is a block diagram that illustrates the sequence of operations of a glazing manufacturing process according to the invention, which comprises,After removal from the mold and placing the glass holder in the open position, a first operation of preparing the glass by cleaning and / or applying a bonding primer to its surfaces intended to come into contact with said glass holder, a second operation of gluing the glass holder, the result of which is illustrated in, a third operation of initial gluing, the result of which is illustrated in, a fourth operation of folding and second gluing, the result of which is illustrated in, and a fifth operation of polymerizing the glue.

[0043] The figures illustrate the manufacture of a glazing 1 according to the invention, comprising a particular and monobloc glass holder 6 for holding a glass 2.

[0044] This glazing 1 is more specifically a vehicle glazing, movable in translation under the action of a window lift mechanism or similar.

[0045] The glazing 1 comprises on the one hand a pane 2, preferably laminated, this pane 2 having an outer face 20 intended to be oriented towards an exterior space EXT, an edge 21, and an inner face 22 intended to be oriented towards an interior space INT, as seen in the figures,,,.

[0046] The glazing 1 also includes at least one glass holder 6, called "holder", having an opening 74, 84, arranged for the passage of a shaft for driving the glass 2.

[0047] The term "shaft" here refers to a mechanical linkage to a window operating mechanism. This shaft may be a threaded rod, for example, that attaches the window carrier, and thus the glazing, to a glazing movement system, allowing its movement relative to a fixed part of the vehicle. The terms "fastener" or "attachment" here refer to mechanical fasteners that attach and detach manually or with a power tool. The attached component is thus in a fixed position; hooking, screwing, or clipping each constitutes a fastener. The window carrier shaft mentioned earlier is therefore a fastener shaft.

[0048] This glass holder 6 has an inner flange 7 that can be positioned opposite the inner face 22 of the glass 2, and an outer flange 8 that can be positioned opposite the outer face 20 of the glass 2. The inner flange 7 and the outer flange 8 have respectively an inner bearing surface 72 and an outer bearing surface 82, which are arranged to bear against each other in a position to hold the glass 2.

[0049] According to the invention, the inner flange 7 and the outer flange 8 are connected to each other by at least one hinge 5 with which they form a single unit, and, as can be seen in the figures, are superimposed on each other to form a clamp gripping the glass 2 in this holding position, in which the glass holder 6 is folded around a folding axis A defined by the at least one hinge 5. In this holding position, the inner flange 7 and the outer flange 8 are held pushed towards each other, and in particular clipped, by a locking cooperation between on the one hand locking means 75 which comprise the inner flange 7, and on the other hand complementary locking means 85 which comprise the outer flange.An optional push button 60 facilitates the locking maneuver by the operator who is installing the glass 2 on the glass holder 6; this push button is set back from the surface of the flange that is furthest from the contact surface between the inner support surface 72 and an outer support surface 82, as seen in the figures.

[0050] The said locking means 75 and additional locking means 85 are located on a lateral edge, and preferably located on two opposite lateral edges of said glass door in the holding position; said locking means and additional locking means are not located on a lower edge, including said hinge, nor located on a top edge of said glass door.

[0051] More specifically, the inner flange 7 and the outer flange 8 respectively comprise at least one inner fixing surface, in particular a flat inner gluing surface 71 carried by an inner arm 70, and at least one outer fixing surface, in particular a flat outer gluing surface 81 carried by an outer arm 80.

[0052] By "fixation" we mean chemical fixings, which cause irreversible molecular changes, unless the bond is broken and the glass holder becomes unusable; gluing is a fixing.

[0053] More specifically, the glazing 1, once assembled, comprises an inner layer of adhesive 79 between at least one inner bonding surface 71 and the glass 2, and an outer layer of adhesive 89 between at least one outer bonding surface 81 and the glass 2.

[0054] In an unillustrated variant, the glazing 1 comprises, between the inner bearing surface 72 and the outer bearing surface 82, a thin adhesive film (less than a quarter of the thickness of the inner adhesive layer 79 or outer adhesive layer 89).

[0055] More specifically, the locking means 75 and the additional locking means 85 are clipping means having an elastic lug arranged to cooperate with a notch, or vice versa, and which are arranged to press the inner arm 70 and the outer arm 80 against the glass 2 in this holding position.

[0056] More particularly, as can be seen in the figures, one of the flanges, in particular the outer flange 8, has two lugs 85 located on either side of this flange, in particular aligned along a parallel to the folding axis A, and as far apart from each other as possible.

[0057] More specifically, the glass holder 6 has at least one elastically deformable area at the locking means 75 and / or the additional locking means 85, and an elastically or plastically deformable area at each hinge 5.

[0058] More specifically, the inner flange 7 and the outer flange 8 each have, as close as possible to at least one hinge 5, a solid portion comprising respectively the inner bearing surface 72 and the outer bearing surface 82, which are preferably flat surfaces. The inner flange 7 and the outer flange 8 each have respectively an inner opening 74 and an outer opening 84 that are superimposed in the holding position, in which holding position the solid portions together form an operating tail for the glass holder 6. More specifically, and without limitation, the inner opening 74 and the outer opening 84 are provided at the level of these solid portions, as shown in the figures.

[0059] More specifically, the inner flange 7 and / or the outer flange 8 has, at the level of the inner arm 70 or respectively of the outer arm 80, and connected to at least one inner bonding surface 71 or respectively to at least one outer bonding surface 81, a housing for receiving, recessed or in contact with the glass 2, at least one component 30 and / or an electrical cable 3 and / or a cutting wire 4.

[0060] More specifically, the inner flange 7 and / or the outer flange 8 includes at least one jumper 83 for the passage and retention of at least one such electrical cable 3.

[0061] More in particular, said housing is delimited, on the side furthest from said window 2 in said holding position, by a surface coplanar to said at least one internal bonding surface 71 or respectively to said at least one external bonding surface 81.

[0062] In the specific, non-limiting variant illustrated in the figures, the translational drive of the window 2 by a window-lifting mechanism (not shown) is achieved through the aligned inner orifices 74 and outer orifices 84. In another variant (not shown), the window 2 has at least one hole provided for its drive by such a window-lifting mechanism, and the inner orifices 74 and outer orifices 84 are arranged for the passage of such a shaft, which also cooperates with this hole in the window 2.

[0063] More specifically, the glazing 1 includes at least two glass doors 6.

[0064] The invention also relates to a vehicle 1000 comprising at least one such glazing 1.

[0065] The invention further relates to a method for manufacturing such a glazing unit 1 that can be moved in translation, particularly in height, along the direction Z of the gravitational field, which constitutes a reference trihedron with a longitudinal direction X (corresponding, in the case of vehicle glazing, to the movement of this vehicle in a straight line), and a transverse direction Y, all orthogonal to each other. This glazing unit 1 comprises, on the one hand, a pane of glass 2, preferably laminated, the pane of glass 2 having an outer face 20 intended to be oriented towards an external space EXT, an edge 21, and an inner face 22 intended to be oriented towards an internal space INT, the glazing unit 1 comprising, on the other hand, at least one pane of glass 6, called a "holder", having an opening 74, 84, arranged for the passage of a shaft for driving the pane of glass 2.The glass holder 6 includes an inner flange 7 positionable opposite the inner face 22 of the glass 2, and an outer flange 8 positionable opposite the outer face 20 of the glass 2. The inner flange 7 and the outer flange 8 respectively include an inner bearing surface 72 and an outer bearing surface 82 arranged to be held pushed towards each other by the cooperation between, on the one hand, locking means 75 included in the inner flange 7, and on the other hand, complementary locking means 85 included in the outer flange 8, in a holding position in which the inner flange 7 and the outer flange 8 clamp the glass 2.According to the invention, in this method the glass holder 6 is made by flat-forming a substantially flat blank using an injection or forming mold in two lower and upper parts, the lower part and said upper part having only flat or straight surfaces or simple undercuts without undercuts, this blank having an inner flange 7 and an outer flange 8 connected to each other by at least one hinge 5 with which they form a single unit, this at least one hinge 5 defining a folding axis A. This blank is placed in an open position at the exit of the mold, in which open position the inner flange 7 and the outer flange 8 are substantially aligned with each other, and respectively have at least one flat inner gluing surface 71 and at least one flat outer gluing surface 81, turned on the same side.

[0066] More specifically, after removal from the mold and said placement in the open position, in a first operation 100 of preparation of the window 2, the window 2 is cleaned and / or receives an adhesion primer on its surfaces intended to come into contact with the window holder 6.

[0067] In a second operation 200 of gluing the glass holder 6, at least one flat inner gluing surface 71 and at least one flat outer gluing surface 81 are cleaned and glued with an adhesive 9, as seen in.

[0068] In a third operation 300 of first bonding the inner flange 7 of the glass holder 6 is positioned resting on a support 50, and the inner face 22 of the glass 2 is bonded with at least one inner bonding surface 71, under a pressure materialized by a thick arrow, with controlled creep of the glue 9 to form an inner glue layer 79 between at least one inner bonding surface 71 and the glass 2, as seen in.

[0069] In a fourth operation 400 of folding and second gluing the blank of the glass holder 6 is folded around the folding axis A and the inner flange 7 and the outer flange 8 are clipped or locked together, by the cooperation between the locking means 75 and the complementary locking means 85. And the outer face 20 of the glass 2 is glued with the at least one outer gluing surface 81 with controlled creep of the glue 9 to form an outer glue layer 89 between the at least one outer gluing surface 81 and the glass 2, as seen in.

[0070] In a fifth polymerization operation 500, the inner glue layer 79 and the outer glue layer 89 are polymerized.

[0071] In an unillustrated variant, the inner bearing surface 72 and / or the outer bearing surface 82 is glued during the third operation 300 of first gluing, and their surfaces are glued together, preferably with a thin film of glue (less than a quarter of the thickness of the inner glue layer 79 or outer glue layer 89), during the fourth operation 400 of second gluing.

[0072] In summary, the present invention allows a window holder to be attached to a pane of glass in a reliable and compact manner. The compact design of the window holder allows for a reduction in its height and / or thickness, respectively along the vehicle's vertical axis Z and transverse axis Y for a side window; this therefore reduces the space required inside the door and thus increases the available interior volume. It also allows for a lighter glazing. The combination of the inner and outer flanges ensures that the forces are evenly distributed on each side of the glass, which is not subjected to stress by the window holder, thus eliminating the risk of damaging the laminated glass.

[0073] The invention thus provides a glazing equipped with at least one very compact and very light glass holder, whose axis can be positioned with precision and which is very securely fixed to the glass without risk of transmitting damaging force to the glass.

[0074] The invention provides a universal solution for the quick, simple, and efficient attachment of glazing to a glazing movement system, offering the possibility of using the same glazing holder regardless of whether the glazing is laminated or not. Thus, when a vehicle series specifies laminated glazing for some models and monolithic glazing for others, an identical glazing holder can be used for both series. The invention also provides a particularly compact and reliable solution for curved glazing.

[0075] The invention provides assembly security and facilitates the operator's work. The one-piece glass holder, foldable into a single position, ensures good relative positioning of the inner and outer flanges on either side of the glass, precise dosing of the adhesive which prevents any lack or excess (and therefore soiling), and controlled creep of the adhesive layer on each side of the glass.

[0076] The invention also allows the easy and secure insertion of components, such as cables, light elements like LED modules, defrosting elements, or others, as well as the insertion allowing for possible dismantling of the glass.
