    [0001] 1 LAMINATED GLAZING COMPRISING A PROFILE CLIPPER CORD. The present invention relates to glazing, and in particular to vehicle glazing, comprising a laminated glazed element comprising an outer glass sheet, an inner glass sheet and a plastic interlayer sheet located between said two sheets of glass.
    [0002] As with any laminated glazed element: the outer glass sheet has an outer face, an edge and an intermediate face which is oriented towards the plastic interlayer sheet; the inner glass sheet has an intermediate face which is oriented towards the interlayer sheet of plastic, a song and an inner face. The glazing according to the invention comprises, along at least one part of at least one edge, a profiled bead having a groove for clipping a cover piece on said profiled bead, said cover piece comprising, seen in transverse section, a harpoon penetrating into said groove during clipping. It is known to ensure the positioning and / or fixing of a cover piece on a glazed element, to use such a profiled bead having a groove. This profiled bead is generally attached to the inner face of the glazed element using an inner wing which is glued against this inner face. For good adhesion of this inner flange to the glazed element which allows force clipping in the groove, this inner flange must be relatively wide (when the profiled bead is observed in cross-section, as is the case). in the majority of documents of the prior art). The prior art has two types of situations: when the cover piece covers at least the groove protruding above the outer face of the glazed element, as for example in the patent applications EP 945 296, DE 3606566; and when the covering piece covers at least the groove without protruding above the outer face of the glazed element, as for example in patent applications WO 2001/045974 or WO 2001/85481. In the first situation, the cover piece must be sufficiently wide, to cover at least the inner wing so that it is not visible from the outside and / or a masking tape is made outside more than the outside. inner wing. In the second situation, a masking tape is made more outboard than the inner wing to cover at least the inner wing so that it is not visible from the outside. These two situations have in common that the cover piece and / or the masking tape are, themselves or together, at least as wide as the inner wing and generally wider than the inner wing; therefore, the clear view through the glazed element is decreased. In addition, because of the presence of the inner fender at the corner between the edge of the inner glass sheet and its inner face, the bead of glue which makes it possible to glue the glazing to the adjacent bodywork must be positioned more towards the center of the glazing; however, this bead of glue must also be masked from the outside. Thus, it is common to consider that along the edge of a glazing equipped with a profiled groove bead, it is a band 30 to 35 mm wide which can not be used to allow to pass the light and thus decreasing the clarity of view. The present invention aims to overcome these disadvantages by providing a glazing comprising a profiled bead which allows clipping force, and therefore which is securely attached to the glazed element, while allowing to increase the clarity of view to through the glazed element. The present invention thus relates to a glazing unit and in particular a vehicle glazing unit, comprising a laminated glazed element comprising an outer glass sheet, an inner glass sheet and a plastic interlayer sheet located between said two sheets of glass, ( directly in contact with or interposed with another sheet of plastic material), said outer glass sheet having an outer face, an edge and an insert face which is oriented towards said interlayer sheet of plastic material, said sheet of glass inner part having an intermediate face which is oriented towards said intermediate sheet of plastics material, an edge and an inner face, said glazing having along at least part of at least one edge a profiled bead having a groove for the clipping a cover piece on said profiled bead, said cover piece comprising, seen e in cross section, a harpoon penetrating into said groove during clipping. This glazing is remarkable in that said profiled bead comprises, seen in cross section, an intermediate flange located between said intermediate face of said outer glass sheet and said intermediate face of said inner glass sheet. 3032414 4 Said intermediate wing is in direct or indirect contact (and in this case via an adhesive material) of said intermediate face of said outer glass sheet and is in direct or indirect contact 5 (and in this case via an adhesive material) of said intermediate side of said inner glass sheet. In a completely surprising manner, it has thus been discovered that it is possible to bond a grooved profiled bead to a laminated glazed element using a space between the outer glass sheet and the inner glass sheet of this element. laminated glazing and that the groove could then be used to perform a reliable clipping, that is to say that the introduction of a harpoon in the groove does not destroy this connection between the profiled bead and the laminated glazed element . The cohesion of the laminated glazed element is thus superior to the damage likely to be caused by the clipping of a harpoon in the groove of such a profiled strip with an intermediate wing which is interposed between the outer glass sheet and the sheet. interior glass of a laminated glazed element. For the mechanical reliability of the clipping, it is preferable that said intermediate wing has a width of between 2.0 and 6.0 mm, or even between 3.0 and 5.0 mm. This width corresponds to the width of the intermediate wing which extends between said intermediate faces of the glass sheets, that is to say from the edge of the glass sheets and in the centripetal direction.
    [0003] The presence of the intermediate wing eliminates the use of an inner wing, or an outer wing, or both; At the very least, it makes it possible to reduce the width of such an inner and / or outer wing and makes it possible to reduce the width of the masking along the edge of the glazing. In an independent variant, said intermediate wing may be integral with said groove 5 and preferably comprises a flat tenon which is inside the intermediate wing and which does not come into contact with said intermediate face of said outer glass sheet and said intermediate side of said inner glass sheet.
    [0004] In an independent variant of the preceding one, said intermediate wing consists of a corrugated post, said corrugated post extending preferably inside the material constituting said groove. Preferably, this corrugated post contacts said intermediate face of said outer glass sheet and said intermediate face of said inner glass sheet. In an alternative independent of the preceding, said intermediate wing does not come into contact with said edge of said plastic, so that the internal tension 20 during clipping does not damage the lamination. In an alternative independent of the preceding, said profiled bead is located against said edge of said outer glass sheet. In an alternative independent of the preceding, said profiled bead is located against said edge of said inner glass sheet. In an alternative independent of the preceding, said profiled bead is located along two lateral edges of said glazed element and / or along an upper edge of said glazed element. In another independent variant, said profiled bead is located only along a lower edge of said glazed element. In an alternative independent of the preceding, said groove is located vis-à-vis the edge of said outer glass sheet 3032414 and / or vis-à-vis the edge of said inner glass sheet. Said intermediate wing preferably has a thickness equal to the thickness between said outer glass sheet 3 and said inner glass sheet 5 and in particular equal to the thickness of said interlayer plastic sheet 4 and in particular equal to 0.76 mm. Preferably, the intermediate wing is thus simply held between the intermediate face of the outer glass sheet and the intermediate face of the inner glass sheet, by wedging, preferably without using adhesive material between the intermediate wing and the interlayer sheet; however, it is possible that the space between the spacer wing and the edge of the spacer sheet is filled with an adhesive material such as glue. In this variant, said intermediate wing is in contact on the one hand with said intermediate face of said outer glass sheet and on the other hand with said intermediate face of said inner glass sheet. In an alternative variant to the previous one, said intermediate wing has a thickness less than the thickness between said outer glass sheet and said inner glass sheet.
    [0005] In this alternative variant, said intermediate wing is not in direct contact with said intermediate face of said outer glass sheet and / or is not in direct contact with said intermediate face of said inner glass sheet: an adhesive material , Such as a bead of adhesive, may be located between said intermediate wing and said intermediate face of said outer glass sheet and / or between said intermediate wing and said intermediate face of said inner glass sheet.
    [0006] In a particular embodiment, said groove is located above said outer face of said outer glass sheet; said groove is then preferably integral with an outer flange.
    [0007] In a very particular variant, said profiled bead has, in cross-section, a m-shape turned at 90 °, with a first recess of the m to accommodate the harpoon of said cover piece and a second recess of the m which encases said sheet of outer glass.
    [0008] Said profiled bead may comprise, seen in cross-section, an outer wing located above (directly on or indirectly on and with insertion of an adhesion band formed by a layer of adhesive or an adhesive tape) of said face. outer of said outer glass sheet. Said profiled bead may also comprise, seen in cross-section, an inner wing located below (directly under or indirectly under and with insertion of an adhesion band formed by a layer of adhesive or an adhesive tape) of said inner face of said inner glass sheet. In the latter two cases, said outer wing and / or inner wing preferably comprises: - a hinge portion of a flexible polymeric material, preferably having a width of between 0.5 and 2.0 mm, or a narrowing section , preferably having a thickness of the order of half the thickness of said outer flange and / or said inner flange which carries it and this, over a width preferably between 0.5 and 2.0 mm . These two elements make it possible to raise the wing with respect to the face of the adjacent glass sheet, in order to facilitate the positioning and fixing of the profiled bead. Preferably, said outer wing and / or said inner wing further comprises an adhesive band formed by a layer of adhesive or a double-sided adhesive tape and which is situated between a centripetal part of the wing and the face of the wing. adjacent glass sheet, to allow this wing to be attached to the adjacent glass sheet. This adhesion band allows the final fixing of the profiled bead to the glazed element after any adjustment of its position vis-à-vis the glazed element. Said outer wing may comprise an upper stop extending perpendicularly to allow the positioning and referencing of said cover piece. In another variant, seen in cross-section, said outer face of said outer glass sheet is free in relation to said groove and said inner face of said inner glass sheet is free in front of said groove. said groove and said intermediate wing has a thickness less than the thickness of said interlayer plastic sheet. Said profiled bead then has neither an outer wing nor an inner wing.
    [0009] In a very specific variant of the invention, or independently of the invention, said glazing comprises along at least part of at least one edge a profiled bead having a groove for clipping a cover piece. on said profiled bead, said cover piece having, in cross-section, a harpoon penetrating into said groove during clipping and said harpoon comprises, in cross section, a lip facing outwardly of said groove, said lip 3032414 9 being preferably of a material different from that of said harpoon. Said harpoon may comprise, in cross-sectional view, a frontal stop located outside said groove in order to limit the penetration height of the harpoon in the groove. In a specific variant of the invention, or independently of the invention, said glazing comprises along at least a portion of at least one edge a profiled bead having a groove for clipping a cover piece. on said profiled bead, said cover piece having, in cross-sectional view, a spear penetrating said groove upon clipping and said groove having a bottom which forms an asymmetric U, with a larger radius of curvature on one side: - on a side close to a rabbet when the groove is opposite a edge of a glass sheet, or - on a side remote from an outer face of the glazed element when the groove is located above this outer face. Thus, this part of the bottom with the larger radius of curvature makes it possible to reduce the space between the groove and the adjacent groove and further increases the compactness of the clipping system.
    [0010] Preferably, the profiled bead, which comprises the groove and the intermediate flange, as well as, optionally, an outer flange and / or an inner flange, is prefabricated: it is manufactured, for example by extrusion through a spinneret. , irrespective of the manufacture of the glazed element (independently of the lamination), and is then attached to the glazed element. The cover piece is a piece intended to be positioned more outwardly than the profiled bead.
    [0011] Advantageously, the present invention makes it possible to provide a profiled profiled cord glazing which is reliable, while decreasing the opaque surface necessary to hide the fastening of this cord, that is to say by making it possible to reduce the width. of the cover piece and / or by making it possible to reduce the width of a masking band. The present invention thus makes it possible to produce a compact clipping system, while being reliable. With the present invention, along the edge of a glazing equipped with the groove profiled bead according to the invention, it is only a strip of 20 to 25 mm wide that can not be used to allow the passage of the light and then decreases the clarity of view.

Within each figure, the proportions between the different elements are respected and the elements in the background are generally not represented, in order to facilitate their reading. The present invention relates to a glazing unit 1, as partially visible in FIG. 1, comprising a laminated glazing element 2 comprising an outer glass sheet 3, an inner glass sheet 5 and a plastic interlayer sheet 4 located between said two sheets of glass. The present invention is described by way of example in the context of an application as vehicle glazing, this glazing providing a separation between an outer space E which is outside the vehicle and an interior space I which is inside the vehicle. The concepts of "outside" and "inside" are therefore considered with respect to this outer space E and this interior space I. The present invention is described in particular by being applied to a vehicle windshield and more specifically in the frame of an application at a left edge of a vehicle windshield, as visible in Figure 3032414 13 1; Figure 1 is a partial horizontal sectional view of the glazing 1 installed in a body bay. For the purpose of this document, the concept of "centripetal" and "centrifugal" is to be considered in relation to the central longitudinal axis of advance of the vehicle equipped with glazing according to the invention as a windshield, that is to say the axis generally called the axis XX 'of the vehicle, as can be seen in Figure 1; the centrifugal direction is perpendicular to this axis and in the direction of this axis while the centripetal direction is perpendicular to this axis and opposite, away from this axis. The glazing 1 is intended to close a bay which is here formed in a vehicle body; an edge of this bay - in this case a left lateral edge - is illustrated in Figure 1 by a rebate 9. The glazed element 2 of the glazing 1 is necessarily a laminated glazing which comprises, from the outside to the inside at least: the outer glass sheet 3, the plastic interlayer sheet 4 and the inner glass sheet 5; however, it is possible for at least one other sheet to be interposed between the outer glass sheet 3 and the plastic interlayer sheet 4 or between the plastic interlayer sheet 4 and the inner glass sheet 5. outer glass 3 has an outer face 30 which faces outwards E, an intermediate face 32 which faces towards the interlayer sheet of plastics material 4, and an edge 31 situated between these two faces. The inner glass sheet 5 has an intermediate face 50 which is oriented towards the plastic interlayer sheet 4, an inner face 52 which is inwardly oriented and a channel 51 situated between these two faces. The interlayer of plastics material 4 has an outer intermediate face 40 which faces 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 50 and which is here in contact with this intermediate face 50, and a edge 41 which is located between these two intermediate faces 32, 42. The glazed element 2 thus has an outer face formed by the outer face 30 of the outer glass sheet 3, an inner face formed by the inner face 52 of the inner glass sheet 5 and a lip between these two faces, corresponding to the edge 31 of the outer glass sheet 3 and to the edge 51 of the inner glass sheet 5 these two songs being here in continuity of one another while being separated by a space corresponding to the thickness of the plastic sheet 4. The glazing 1 is intended to be adhered to the rabbet 9 by means of an unillustrated bead of glue, which is situated between the inner face 52 of the inner glass sheet and an adjacent part of the rabbet 9.
    [0013] The glazing 1 comprises, in addition to the glazed element 2, along at least a portion of at least one edge a profiled bead 6 having a groove 60 for clipping a cover piece 7 onto said profiled bead 6 , said cover piece 7 having, in cross-sectional view, a harpoon 70 penetrating into said groove 60 during clipping. The groove 60 has a mouth and a bottom: when clipping the cover piece 7, the harpoon 70 enters the groove 60 through the mouth and in the direction 3032414 from the bottom; generally, in the clipped position, the harpoon 70 does not touch the bottom of the groove. The mouth of the groove, through which the harpoon 70 is introduced, is made by two drains: a centrifugal drain 67, situated to the left of the harpoon 70 in FIG. 1 and a centripetal drain 68, located to the right of the harpoon 70 on this same figure. These two drains are intended to guide the harpoon 70 accurately towards the bottom of the groove 60 during clipping of the harpoon 70.
    [0014] The cover piece 7 is intended to be positioned more outwardly than the profiled bead 6 and to cover it at least partially when the glazing 1 is viewed from the outside E. This is, in the context of FIG. the application to a side edge of a windshield, a piece intended to limit the penetration of water on the side of the glazing through the presence of a lip 75 located against the rabbet 9 and to embellish. It can be a hubcap. The profiled bead 6 comprises, seen in cross section 20 as in FIG. 1, an intermediate flange 61 which is situated between the intermediate face 32 of the outer glass sheet 3 and the intermediate face 50 of said inner glass sheet 5. This flange interlayer 61 is in contact with one side of the intermediate face 32 of said outer glass sheet 3 and the other side of the intermediate face 50 of the inner glass sheet 5 and extends between these two faces. Along the edge of the glazed element comprising the profiled bead 6, the edge 41 of the plastic interlayer sheet 4 is therefore recessed centripetally with respect to the edges 31, 51 respectively of the outer glass sheet and the sheet of glass. inner glass.
    [0015] FIG. 1 illustrates a first embodiment of the invention according to which the groove 60 is lateral: the groove 60 of the profiled bead extends along the left edge of the glazed element, next to the edge of the groove 60; glazed element 2.
    [0016] In addition, in this first embodiment, the mouth of the groove is oriented outwards. In this first mode, moreover, the two gullies are located more on the outside than the outer face 30 of the outer glass; they are located above this outer face 30 when the extension of this face beyond the edge 31 is considered. The bottom of the groove 60 may be located further inward than the inner face 52; this does not interfere with the positioning of the glazing in the bodyshell 15 because there is room between the inner face 52 and the rabbet 9 for the bead of glue (not shown). The two mouths of the mouth of the groove are each in the form of a hammer with the heads almost opposite each other, the centrifugal drain 67 being situated slightly outside the centripetal outlet. The harpoon is double: it is constituted, seen in cross section, two bosses facing away from each other and offset, the centrifugal boss, intended to come under the centrifugal drain 67 being located slightly more on the outside only the centripetal boss intended to come under the centripetal drain 68. The clipping thus consists in the penetration of the harpoon 70 inside the groove 60 and more precisely of the two bosses of the harpoon inside the groove 60 and under both drains. For proper restraint, the width of the mouth, the shorter between the two drains is less than the width of the two bosses at the widest.
    [0017] In FIG. 1, the intermediate wing 61 is a single wing, made of the same material and made of material with the groove 60, without reinforcement. As can be seen in this FIG. 1, the entire outer face of the intermediate wing 61 is in contact with the intermediate face 32 of said outer glass sheet 3 and the entire inner face of the intermediate wing 61 is contact of the intermediate face 50 of the inner glass sheet 5.
    [0018] The intermediate wing 61 thus occupies the space located from the plumb under the edge 31 of the outer glass sheet and above the edge 52 of the inner glass sheet and towards the intermediate sheet of material plastic 4; the spacer wing thus has a thickness identical to the thickness of the plastic interlayer sheet 4 (here in this case a thickness of 0.76 mm). However, it does not come into contact with the plastic interlayer sheet 4 in order not to disturb the cohesion produced by this interlayer of plastic material 4 with the two sheets of glass, that is to say in order to do not disturb the foliation. The intermediate flange 61 has a width 1, illustrated in FIG. 2, of between 2.0 and 6.0 mm, and even between 3.0 and 5.0 mm. This width is sufficient to allow good maintenance of the intermediate wing between the outer glass sheet and the inner glass sheet without disturbing the cohesion of the plastic interlayer sheet 4 with the two sheets of glass. The glazed element 2 is manufactured before the fastening of the profiled bead 6 to the glazed element 2, that is to say that the lamination of the glass sheets 3, 5 with the plastic sheet in order to form a laminated glazing is 3032414 18 operated before fixing the profiled bead 6 to the glazed element 2. To attach the profiled bead 6 to the glazed element 2, it is necessary to: 5 - insert the intermediate flange 61 in the space between the intermediate face 32 of the outer glass sheet and the intermediate face 50 of the inner glass sheet, - then adhere the profiled bead to the glazed element 2. This adhesion can be achieved by means of an adhesion band formed by a layer of adhesive or an adhesive tape and in particular a double-sided adhesive tape. The profiled bead 6 comprises, seen in cross-section, an outer flange 63 situated above the outer face 30 of the outer glass sheet 3; the outer wing 63 is thus more outward than the outer face 30. An adhesive strip 8 formed by a layer of adhesive 20 or a double-sided adhesive tape is located between a centripetal portion of the outer wing 63 and the outer face 30. This adhesion band allows to fix this outer flange 63 to the outer face 30 underlying.
    [0019] In Figure 1, the groove 60 has a height of about 7.8 mm and a width of about 5.5 mm; the intermediate wing 61 has a width 1 of about 5.0 mm, the outer wing 63 has a width of about 12 mm and the adhesion band 8 has a width of about 6 mm. In FIG. 1, it suffices that the cover piece 7 overflows above the outer face 30 over a width 17 of approximately 25 mm starting from the edge of the glazed element in order to mask both the outer wing 63 , the wing 61 3032414 19 and the adhesive bead (not shown) for fixing the glazing to the body. In order to keep the outer wing 63 away from the outer face 30 during the insertion of the intermediate wing 61 into the space between the two sheets of glass, the outer wing 63 has a hinge portion 64 made of a polymeric material flexible, preferably having a width 164, visible in Figure 2, between 0.5 and 2.0 mm.
    [0020] This hinge portion is used to lift the outer wing 63 to position the adhesive strip 8 (in the case of a glue layer) or to activate the adhesive strip 8 (in the case of a double-sided adhesive tape with a film temporary protection which can be peeled off) and make it possible to fix the outer wing 63 to the underlying outer face 30. This lifting movement is illustrated by the arrow S in FIG. 2. FIG. 2 also illustrates an independent variant of FIG. 1 according to which the intermediate wing 61 comprises a flat post 62, completely integrated into the interior of the door. intermediate flange 61 and which does not come into contact with the intermediate face 32 of the outer glass sheet 3 or with the intermediate face 50 of the inner glass sheet 5, in order to stiffen the intermediate flange 31. This tenon is flat in the space between the intermediate face 32 and the intermediate face 50 but has a bend in line with the edge 31 of the outer glass sheet 3 and continues inside the material 30 constituting the groove 60 in the portion of this groove which is against this edge 31, to further stiffen the intermediate wing 61. In another variant, illustrated in Figures 3 and 4 and independent of that of Figures 1 and 2, the wing 3032414 20 intercal area 61 consists of a corrugated post 62 '. This corrugated post contacts, thanks to its longitudinal corrugations, with the intermediate face 32 of the outer glass sheet 3 and with the intermediate face 50 of the inner glass sheet 5, in order to effectively maintain the wing interlayer between these two faces. This corrugated post has a bend in line with the edge 31 of the outer glass sheet 3 and extends inside the material constituting the groove 60, 10 towards the outside, in the portion of this groove which is against this edge 31, in order to stiffen the intermediate flange 61. FIG. 5 illustrates a variant independent of the preceding ones in which the outer flange 63 has a section narrowing 66, preferably having a thickness of the order of half of the thickness of said outer flange 63. This section narrowing 66 allows, in place of the hinge portion 64, to lift the outer flange 63 according to the lifting movement illustrated by the arrow S. The hinge portion 64 , just like the narrowing of section 66, makes it possible to generate an elastic deformation zone at the connection between the groove 60 and the outer wing 63.
    [0021] Although this is not illustrated, for this first variant, the profiled bead 6 could comprise, seen in cross-section, an inner wing located below (directly under or indirectly under and with the interposition / insertion of a layer of glue or adhesive tape) of the inner face 52 of said inner glass sheet 5. In this case, this inner flange preferably comprises a hinge portion or a sectional narrowing.
    [0022] FIG. 6 illustrates an independent variant of the preceding embodiments in which an elongate centrifugal drain 67 ', longer than the centrifugal drain 67 of the preceding variants, makes it possible to guide the harpoon 70 towards the mouth of the groove 60. In the variants illustrated in FIGS. 1 to 11, the groove 60 is located opposite the edge 31 of said outer glass sheet 3 and opposite the edge 51 of said inner glass sheet 5.
    [0023] In the variants illustrated in FIGS. 1 to 6, the profiled bead 6 is situated against the edge 31 of said outer glass sheet 3. In these variants, the profiled bead 6 is situated against the edge 51 of said inner glass sheet 5 .
    [0024] However, it is possible that the profiled bead 6 is not located against the edge 31 of the outer glass sheet 3 and / or is not located against the edge 51 of the sheet of said inner glass sheet 5, as visible in Figure 7.
    [0025] In this variant, the groove 60 thus has a flexibility with respect to the glazed element 2 and more precisely with respect to the intermediate wing 61: - the absence of contact with the edge 31 allows a rotation of the groove relative to to the intermediate wing and 25 in the direction of this song during clipping, and - the absence of contact with the edge 51 allows a rotation of the groove relative to the intermediate wing and towards this edge during clipping. FIG. 8 illustrates an independent variant of the preceding 30 in which the harpoon 70 comprises, in cross section, in its part inside the groove 60, a lip 71 facing outwardly of said groove 60. This lip 71 is located above the 3032414 22 centripetal boss of the harpoon and just housed, during clipping, under the centripetal drain 68. This lip 71 may be of a different material from that of harpoon 70 and in particular a softer material.
    [0026] This lip makes it possible to reduce the clipping force during the introduction of the harpoon 70 in the groove 60 while increasing the effort required for declipping. FIG. 9 illustrates an independent variant of the preceding embodiments in which, viewed in cross-section, the outer face 30 of the outer glass sheet 3 is free in relation to the groove 60: the profiled bead does not have any outer wing. In addition, the inner face 52 of the inner glass sheet 5 is free vis-à-vis the groove 60: the profiled bead has no inner flange. On the other hand, in this variant, the groove 60 is the same as in FIGS. 5 to 8, but the intermediate wing 61 is different: it has a thickness less than the thickness between the outer glass sheet and the outer sheet. inner glass, i.e. less than the thickness of the plastic interlayer sheet 4. In this alternative variant, the intermediate flange 61 is not in direct contact with the intermediate face 32 of the sheet of outer glass and is not in direct contact with the intermediate face 50 of the inner glass sheet: an adhesive material 8 ', such as a bead of glue, is located between the intermediate wing and the intermediate face 32 of the outer glass sheet and between the intermediate wing and the intermediate face 50 of the inner glass sheet. The intermediate wing 61 is thus in indirect contact with the intermediate face 32 of the outer glass sheet 3032414 23 and is in indirect contact with the intermediate face 50 of the inner glass sheet. Thus, the intermediate wing 61 is glued to the glass sheets; although this is not illustrated, it could also be glued to the edge 41 of the plastic interlayer sheet 4. It is also possible for the insert flange to be in direct contact with an intermediate face 32, 52 and either in indirect contact, via the adhesive material, the other intermediate face (respectively 52, 32). FIG. 10 illustrates an independent variant of the preceding embodiments in which the harpoon 70 comprises, seen in cross-section, a frontal stop 72 situated outside said groove 60. This frontal stop 72 is here centrifugal and is located against the centrifugal drain 67 during clipping, but it could be centripetal and be against the centripetal 68 when clipping; it is intended to limit the penetration of the harpoon 70 into the groove 60. FIG. 10 further shows that the outer wing 63 may comprise an upper stop 67 extending perpendicularly to allow the positioning and positioning With reference to the cover piece 7. Preferably, as shown in FIGS. 1 to 11, the bottom of the groove 60 does not form a symmetrical U, but an asymmetrical U, with a larger radius of curvature on the the rebate 9, which reduces the size of the groove vis-à-vis the adjacent rabbet. More particularly, the use of an asymmetrical bottom groove with a larger radius of curvature on the rabbet side increases the inclination of the rebate adjacent to the edge of the glazed element 3032414. an angle α of the order of 20 ° and then decrease the distance d between the rabbet 9 and the centrifugal bottom of the groove, from a value of about 9 mm to a smaller value of about 4.5 mm. This represents a gain of 5 important place and thus makes the clipping system more compact and increase the size of the glazing. In FIG. 12 is illustrated a second embodiment of the invention according to which the groove is no longer lateral but superior: the groove 60 of the profiled bead is no longer located next to the edge of the glazed element 2, as in the first mode and Figures 1 to 11, but above the outer face 30 of the outer glass sheet 3, i.e. above the outer face of the glazed element 2 Of course, as for the first mode, in this second mode, the profiled bead 6 comprises an intermediate flange 61 which is situated between the intermediate face 32 of the outer glass sheet 3 and said intermediate face 50 of said glass sheet. 5. This intermediate wing 61 is in contact on the one hand with the intermediate face 32 of said outer glass sheet 3 and on the other side with the intermediate face 50 of the inner glass sheet 5.
    [0027] Thus, the groove 60 is integral with an outer flange 63; the outer wing 63 carries the groove 60 whose mouth can be centripetal, as shown in Figure 12, or can be centrifuged, as shown in Figure 13.
    [0028] In order to maintain the outer wing 63 remote from the outer face 30 during the insertion of the intermediate wing 61 into the space between the two sheets of glass, the outer wing 63 has a hinge portion 64 made of a material flexible polymer, preferably having a width 164, such as that shown in FIG. 2, between 0.5 and 2.0 mm. This hinge portion is used to lift the outer wing 63 to position the adhesive strip 8 (in case of a glue layer) or to activate the adhesive strip 8 (in the case of a double-sided adhesive tape with a film temporary protection which can be peeled) and allow the outer wing 63 to be secured to the underlying outer face. This lifting movement is illustrated by the arrow S in FIGS. 12 and 13. In FIG. 12, the profiled bead 6 has, in cross-section, a m-shape turned at 90 ° (that is, not horizontal, but vertical with respect to the outer, inner faces of the glazed element). A first recess of the m carries the groove 60 to accommodate the harpoon 70 of the cover piece 7 and a second recess of the m encloses the outer glass sheet 3, preferably coming against the edge 31 of the outer glass sheet 3 .
    [0029] In FIG. 13, the profiled bead 6 has, in cross-section, an inverted S shape seen as in a vertical mirror (that is with the upper loop open not to the right but to the left and the low loop then open to the right). A first recess of the inverted S 25, the upper recess open to the left, realizes the groove 60 to accommodate the harpoon 70 of the cover piece 7 and a second recess of the S encases the outer glass sheet 3, preferably coming from the edge 31 of the outer glass sheet 3.
    [0030] In FIGS. 12 and 13, the intermediate wing 61 is a simple wing, similar to that of FIG. 1, without reinforcement. It does not come into contact with the plastic interlayer sheet 4.
    [0031] This intermediate wing 61 of the second embodiment may comprise a flat post, as illustrated in FIG. 2, to reinforce it, or comprise a corrugated post, as illustrated in FIGS. 3 and 4.
    [0032] In this second mode, it is also possible for the outer wing 63 to have a section narrowing 66, as illustrated in FIG. 5. Although this is not illustrated, for this second mode, the profiled bead 6 could comprise, seen in cross-section, an inner flange underneath (directly under, or indirectly under and with interposition / insertion of a layer of glue or an adhesive tape) the inner face 52 of said inner glass sheet 5. In this case, this inner flange 15 preferably comprises a hinge portion or a section narrowing. In this second mode, it is possible for the groove 60 to have an extended upper throat, similar to the extended centrifugal throat of FIG.
    [0033] In this second mode, it is possible for the profiled bead 6 to be spaced from the edge of the glazed element, as illustrated in FIG. 7, with the profiled bead 6 which is not in contact with the edge 31 of said sheet. outer glass 3, and / or with the edge 51 of said inner glass sheet 5, to give more flexibility to the profiled bead 6. In this second mode, alternatively or cumulatively: the harpoon 70 may comprise a lip 71 as illustrated in Figure 8; the intermediate wing 61 can be glued, as illustrated in FIG. 9; The harpoon 70 may comprise a frontal stop 72 and / or the inner wing 65 may comprise a stop, similar to the upper stop 67 illustrated in FIG. 10; although this is not illustrated, the bottom of the groove 60 may not form a symmetrical U, but may form an asymmetric U, with a larger radius of curvature on the opposite side to the outer face 30, which allows reduce the size of the groove vis-à-vis the cover piece.
    [0034] In Fig. 14 is illustrated a third embodiment of the invention according to which the groove is lateral but does not protrude from a considered artificial plane which would be in continuity with the outer surface 30 of the outer glass sheet 30. the profiled bead is flush with the continuity of the outer surface 30 of the outer glass sheet 30; he is "flush". In this third embodiment of the invention, the profiled bead does not protrude further than the outer face 30 of the outer glass sheet 3. In this third variant, it is thus possible that the cover piece is present above the groove 60 but does not protrude centripetally beyond the edge 31 above the outer face 30, or does not extend centripetally beyond the centripetal gutter 67. It is possible for the centripetal hood 67 to be located less outside than the centrifugal drain 68 so that when the cover piece 7 is clipped into the groove 60 an outer face of the cover piece 7 is in continuity with the outer surface 30 of the outer glass sheet 3; the cover piece is then "flush" with the outer glass sheet 30.
    [0035] Of course, as for the first mode, in this third mode, the profiled bead 6 comprises an intermediate wing 61 which is located between the intermediate face 32 of the outer glass sheet 3 and the intermediate face 50 of said sheet of glass. inner glass 5. This intermediate wing 61 is in contact with the intermediate face 32 of said outer glass sheet 3 and on the other side of the intermediate face 50 of the inner glass sheet 5.
    [0036] The intermediate wing 61 has a width 1 of between 2.0 and 6.0 mm, or even between 3.0 and 5.0 mm. This width is sufficient to allow a good maintenance of the intermediate wing between the outer glass sheet and the inner glass sheet without the risk of disturbing the cohesion of the interlayer plastic sheet 4. The profiled bead 6 comprises, seen in transverse section, an inner wing 65 located below the inner face 52 of the inner glass sheet 5; the inner flange 65 is thus more inward than the inner face 52. An adhesive strip 8 formed by a layer of adhesive or a double-sided adhesive tape is located between a centripetal portion of the inner flange 65 and the inner face 52. This adhesion band allows to fix the inner flange 65 to the inner face 52 overlying. In order to be able to keep the inner wing 65 away from the inner face 52 during the insertion of the intermediate wing 61 into the space between the two sheets of glass, the inner wing 65 comprises a hinge portion 64 made of a polymeric material. flexible. This hinge portion is used to lift the inner flange 65 to position the adhesive strip 8 (case 3032414 29 of a glue layer) or to activate the adhesive strip 8 (in the case of a double-sided adhesive tape with a temporary protective film which can be peeled) and allow the inner flange 65 to be attached to the inner face 52 above. This lifting movement is illustrated by the arrow S in FIG. 14. In FIG. 14, the intermediate wing 61 is a simple wing, similar to that of FIG. 1, without reinforcement. It does not come into contact with the plastic interlayer sheet 4. This intermediate wing 61 of the third mode may comprise a flat tenon, as illustrated in FIG. 2, to reinforce it, or comprise a corrugated tenon, as illustrated in FIGS. 3 and 4.
    [0037] In this third mode, it is also possible for the inner wing 65 to have a section narrowing 66, as illustrated in FIG. 5; A section narrowing, just like a hinge portion, makes it possible to generate an elastic deformation zone at the connection 20 between the groove 60 and the inner wing 65. In this third mode, it is possible for the groove 60 to include a centrifugal drain. elongate, similar to the elongate centrifugal drain of FIG. 6. In this third mode, it is possible for the profiled bead 6 to be spaced from the edge of the glazed element, as illustrated in FIG. 7, with the profiled bead 6 which is not in contact with the edge 31 of said outer glass sheet 3 and / or with the edge 51 of said inner glass sheet 5, in order to give the profiled bead 6 more flexibility. In this third mode, alternatively or cumulatively: the harpoon 70 may comprise a lip 71, as illustrated in FIG. 8; The spacer wing 61 can be glued, as illustrated in FIG. 9; the harpoon 70 may comprise a frontal stop 72 and / or the inner wing 65 may comprise a stop, similar to the upper stop 67 illustrated in FIG. 10; - Although this is not visible in Figure 14, the bottom of the groove 60 may not form a symmetrical U, but form an asymmetric U, with a larger radius of curvature on the side of the rabbet, which allows 10 reduce the size of the groove vis-à-vis the adjacent rabbet, as shown in Figure 11, with the advantages described for this figure. In Figure 14, the groove 60 has a height h60 of about 6.8 mm and a width 160 of about 5.5 mm; The intermediate flange 61 has a width 1 of 5.0 mm, the inner flange 65 has a width 165 of about 12 mm and the adhesive strip 8 has a width 18 of about 6 mm. In this figure, a masking tape (not shown) 20 located more outside than the intermediate wing and 20 mm wide starting from the edge of the glazed element will be sufficient to mask both the wing interlayer and the bead of glue (not shown) for fixing the glazing to the body.
    [0038] Although not shown, in a variant of the first mode or the third mode, the outer face 30 of the outer glass sheet 3 may be free in relation to the groove 60 and the inner face 52 of the inner glass sheet 5 can be free in relation to the groove 60; in this case, the profile bead 6 has neither an outer wing nor an inner wing. In order for the intermediate flange 61 to hold the profiled bead correctly, it then has a thickness less than the thickness of the plastic interlayer sheet 4 and is bonded between the intermediate face 32 and the intermediate face 50 in the same way 9. Whatever the embodiment, the material constituting the groove 60 may be reinforced by the presence, inside, of an insert 69, such as for example a metal insert, which makes it possible to increase the rigidity of the groove. This insert may be for example an aluminum profile with a thickness of 0.4 mm.
    [0039] The present invention is applicable to any glazing and in particular to any vehicle glazing. It can be applied to any edge of this glazing: left, right, up or down and in particular to several of these edges at the same time, or all these edges at the same time. It can be applied in particular to the clipping, in the lower part of a vehicle windshield, a piece of plastic cover sometimes called "water box" or "awning grid".
    [0040] The profiled bead 6 may be located along two side edges of the glazed element 2 and / or along an upper edge of the glazed element. It may not be located along a low edge, particularly when the glazing is a vehicle windshield and the glazing has another type of profiled bead along the bottom edge.
