Description

GLAZING WITH RETAINING CLIP FOR COVER PIECE

The invention relates to the field of glazing comprising along at least part of at least one longitudinal edge a cover piece, in particular constituting a trim, this cover piece being attached to a window with the aid of one or more clips.

The invention is described with regard to an application of vehicle glazing comprising a window, in particular a laminated window then comprising an outer sheet of glass, an inner sheet of glass and an intermediate sheet of plastic material located between said two sheets of glass , said window having an outer face, an edge and an inner face.

The invention relates more particularly to a glazing comprising at least one clip for attaching said cover piece to said glazing, said clip comprising, seen in cross section, a base located plumb under an inner edge of said pane being fixed to this inner edge.

The prior art knows a clip solution for attaching a cover piece to a pane of German patent application No. DE 199 39 191. In this document, when the clip is seen in cross section, a hollow rib of the open clip towards the outside extends in the direction of the interior, and essentially being further inside than the interior face of the pane, to accommodate a harpoon which is provided on the interior face of the cover piece, also towards the interior.

The prior art also knows several solutions for attaching a cover piece to a window which use, instead of clip(s) or in addition, a profiled cord.

A profiled bead is different from a clip in that a clip constitutes a local, or localized, attachment at a precise location along the edge of the glazing, over a few millimeters to a few centimeters at most, whereas a profiled bead is a part that generally extends all along the edge of the glazing. A shaped bead can provide a stronger attachment of the cover piece to the glass than a clip, but it requires more material; a profiled bead attachment configuration therefore costs more and makes the glazing heavier than a clip(s) attachment configuration.

The prior art knows in this respect the international patent application No. WO 2011/018379A1 which proposes an attachment of a cover piece with a profiled cord while leaving a space between the window and the cover piece.

In the documents presented above, the cover piece has the particularity of not being attached only to the glazing: in the final vehicle, the cover piece is attached by other means to the vehicle body.

The present invention relates more particularly and preferably to a glazing whose cover piece extends all along one edge of the glazing. Such a glazing edge cover piece belongs to the glazing. In particular in this case, the glazing includes the cover piece when it is handled to be positioned in the bay of the bodywork that it must close; preferably, in the final vehicle, the glazing edge cover piece is not at all directly attached or attached directly to the vehicle body; it is attached or fixed to the vehicle at the same time as the glazing to which it belongs because (or when) the glazing itself is, respectively, attached or fixed to the vehicle.

There exist in the prior art, as for example in the international patent application No. WO 07/003823, clips for attaching a glazing edge cover piece but these clips are not for attaching the piece directly to the window. glazing edge cover piece: these are clips for indirectly attaching the glazing edge cover piece to the pane: these clips attach the glazing edge cover piece to a profiled cord which itself is fixed to the pane by extrusion in situ, by molding in situ ("encapsulation") or by gluing the prefabricated profiled bead.

The present invention intends to constitute a solution for a quick, simple and effective fixing of a covering piece along an edge of a glazing, without providing for a profiled joint bead fixed to the window, and located between the window and the cover piece, in order to save the material and the weight of such a profiled seal bead.

The present invention intends to constitute a particularly compact and reliable solution for fixing a covering part in a glazing.

To this end, the subject of the invention is a vehicle glazing comprising a window, in particular a laminated window comprising an outer sheet of glass, an inner sheet of glass and an intermediate sheet of plastic material located between said two sheets of glass, said pane having an exterior face intended to be oriented towards an exterior space, an edge and an interior face intended to be oriented toward an interior space, the said glazing comprising along at least a part of at least one longitudinal edge a piece of cover, elongated, constituting in particular a hubcap.

Said glazing further comprises at least one clip for attaching said cover piece to said window, said clip comprising, seen in cross section, a base located plumb under an inner edge of said window being fixed to this inner edge.

Said glazing is remarkable in that said clip further comprises, in the centripetal direction starting from said base:
- a base extension located in the extension of said base being further inside than said window, then
- a hooking portion located further inside than said cover piece and having, at a centripetal end, a distal lateral boss
and in that said cover piece has, at a centripetal end, a distal lateral rib which comes to cover said distal lateral boss, in order to allow said distal lateral rib to be held mechanically against said distal lateral boss. This holding performs distal clipping of said cover piece on said clip.

Preferably, said clip is attached only to the inner edge of said window; it is not attached to the edge of said window, nor to the outer edge of said window, in order to refer only to the inner edge of said window.

Preferably, said clip is at a distance (without contact) from the edge of said pane and at a distance (without contact) from the outer edge of said pane, in order to leave a free space opposite the edge of said pane which is large enough.

By "fastener" or "attachment" within the meaning of the present invention, it is necessary to understand the mechanical fasteners, which are attached and detached manually or using a mechanical tool. What is attached is thus in a fixed position; hanging or clipping are each an attachment.

By “fixing” within the meaning of the present invention, it is necessary to understand chemical fixings, which generate irreversible molecular modifications, except to break the bond and to make the clip unusable; gluing is fixing.

Each of these two expressions excludes the other.

A rib is a protruding edge of material. It is generally made in two parts which, here, seen in section, are preferably positioned substantially at right angles.

Preferably, to increase the reliability of the attachment, said hooking portion also has, at a centrifugal end, a proximal lateral boss and said cover piece has, at a centrifugal end, a proximal lateral rib which covers said boss proximal side, to allow said proximal side rib to be mechanically held against said proximal side boss. This holding performs a proximal clipping of said cover piece on said clip.

Preferably, to increase the compactness of the attachment, said distal lateral boss, and more preferably said proximal lateral boss, is located opposite an edge of said inner glass sheet.

Preferably, said distal lateral boss and said proximal lateral boss face each other; they occupy an identical position in an exterior-interior direction.

Preferably, to prevent the presence of dirt, said distal lateral rib and/or said proximal lateral rib comprise(s) respectively a distal sealing lip and/or a proximal sealing lip.

Preferably, to increase the compactness of the attachment, said hooking portion has an outer surface which is located opposite the edge of said window, and preferably opposite an edge of said interlayer of plastic material.

Preferably, to increase the reliability of the attachment, an adhesive material is located, in contact, between an inner face of said cover piece and said hooking portion, this adhesive material being preferably positioned in an outer hollow of said portion of hooking.

Preferably, to increase the precision of the attachment, a spacer is located further inside than said attachment portion.

Preferably, to increase the compactness of the assembly thus fixed, said outer face of said cover piece is located in the extension of said outer face of said window.

Preferably, to increase the compactness of the attachment, the overall thickness of said cover piece is between 0.8 and 1.5 times the thickness of said window, or even is between 0.9 and 1.2 times the thickness of said window.

Preferably, to increase the compactness of the attachment, the overall thickness of said clip is between 1.8 and 2.5 times the thickness of said window, or even is between 1.9 and 2.2 times the thickness of said window.

The glazing according to the invention preferably comprises a plurality of clips distributed along said longitudinal edge, each clip being fixed to the inside face of said window and extending in the centripetal direction beyond the edge of said window.

Advantageously, the present invention makes it possible to fix a covering part in a glazing in a reliable and compact manner. A compact fixing solution makes it possible to reduce the height of the rebate of the opening intended to accommodate the glazing on its periphery; this therefore makes it possible, for the same exterior configuration, to increase the volume available inside.

The following examples and figures illustrate the invention in a non-limiting manner.

illustrates the glazing of Figure 1, without the trims.

illustrates a cross-sectional view at the location of a clip of a first variant of a glazing according to the invention.

illustrates the sectional view of Figure 3 when the glazing is positioned in a motor vehicle body bay.

illustrates a cross-sectional view at the location of a clip of a second variant of a glazing according to the invention.

The present invention relates to a glazing 1, as seen in Figure 1, comprising a window 2 which itself comprises a window 2 '. The pane 2 is laminated and comprises an outer sheet of glass 3, an inner sheet of glass 5 and an intermediate sheet of plastic material 4 located between said two sheets of glass, and in contact with these two sheets of glass.

The present invention is described by way of example in the context of an application as vehicle glazing, this glazing forming a separation between an exterior space E which is exterior to the vehicle and an interior space I which is interior to the vehicle. The notions of “exterior” and “interior” are therefore considered in relation respectively to this exterior space E and this interior space I.

In the figures, the glass sheets are each illustrated with a rounded edge; however, these edges can be straight, with the edges between the edges and the faces which are then at right angles.

The present invention is described in particular by being applied to a vehicle roof glazing and more specifically in the context of an application to a left and right edge of a vehicle roof glazing, as visible in Figure 1; FIG. 1 being a perspective view, from the outside, of the glazing 1 before its installation in a body bay.

In the context of this document, the notion of "centripetal" and that of "centrifugal" is to be considered with respect to the central longitudinal axis of advance of the vehicle equipped with the glazing according to the invention as a windshield, c 'that is to say the axis generally called the X-X axis' 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 provided in a body of the vehicle; one edge of this bay – in this case a left side edge – is illustrated in figure 4 by a rebate 9.

The pane 2 of the pane 1 can be a monolithic pane, consisting of a single sheet of glass but is preferably here a laminated pane which comprises, from the outside inwards and in contact, at least: the glass sheet outer 3, the interlayer plastic sheet 4 and the inner glass sheet 5; however, it is possible for at least one other sheet to be interposed between the outer sheet of glass 3 and the interlayer of plastic material 4 or between the interlayer of plastic material 4 and the inner sheet of glass 5.

The outer glass sheet 3 has an outer face 30 which is oriented towards the outside E, an intermediate face 32 which is oriented towards the intermediate sheet of plastic material 4, and an edge 31 located between these two faces.

The inner sheet of glass 5 has an intermediate face 50 which is oriented towards the intermediate sheet of plastic material 4, an inner face 52 which is oriented towards the interior I and an edge 51 located between these two faces.

The plastic insert sheet 4 has an outer insert face 40 which is oriented towards the insert face 32 and which is here in contact with this insert face 32, an inner insert face 42 which is oriented towards the insert face 50 and which is here in contact with this spacer face 50, as well as an edge 41 which is located between these two spacer faces 32, 42.

The pane 2 thus has an outer face 20 produced by the outer face 30 of the outer glass sheet 3, an inner face 22 produced by the inner face 52 of the inner glass sheet 5 and an edge 21 located between these two faces, corresponding to the edge 31 of the outer sheet of glass 3, to the edge 41 of the intermediate sheet of plastic material 4 and to the edge 51 of the inner sheet of glass 5, these three edges being here substantially in the continuity of one of the another, plus or minus 1 millimeter.

The glazing 1 is intended to be glued to the rabbet 9 using a bead of glue, not shown, which is located between the inner face 52 of the inner glass sheet and an adjacent part of the rabbet 9.

The glazing 1 comprises, in addition to the glazing 2, along at least part of at least one edge (here the left longitudinal edge), an elongated cover piece 6, here constituting a trim.

This cover piece 6 extends next to the pane 2, without covering it at all; it has an outer face 60 and an inner face 62.

This cover piece 6 has a central, solid body 61 extending all along the cover piece, as well as, seen in cross section:

- on the one hand, at a centripetal end, a distal lateral wing 63, oriented inwards and which ends in a distal lateral rib 64, and

- on the other hand, at one centrifugal end, a 63' proximal lateral wing, facing inwards.

The proximal side wing 63' is closer to the edge 21 of the window than the distal side wing 63.

Each side wing 63, 63' extends all along the cover piece, towards the inside I. The angle between the body 61 and a side wing is preferably slightly less than 90°, in particular between 70° and 85°, here 80°; thus the general orientation of the two lateral wings is secant at a point (not materialized here).

A rib is an end of a side wing which is in two parts, a first part linked to the side wing and oriented substantially perpendicular to the outside-inside direction then a second part, at the end of the first, which is oriented substantially in the exterior-interior direction. A rib thus has an angle that can serve as a support.

To locally attach the cover piece 6 to the glazing 1, the latter further comprises at least one clip 7.

By nature, a clip is a small part compared to the cover part, which preferably extends all along the glazing and thus has a length of several decimeters. A clip preferably has a length less than one tenth of the length of the cover piece. A clip preferably has a length of a few millimeters to at most a few centimeters in length.

A clip is a solid, plastic part. It is possible to provide one (or more) strip(s) of internal reinforcement inside a clip to increase its rigidity.

As visible in Figure 2, the glazing 1 comprises a plurality of clips 7 which are distributed along the longitudinal edge of the window, to attach the cover piece 6 to the window 2 in as many places as there are clips .

The distance between each clip is preferably identical but the clips can be closer together in places where it is desired that the retaining force of the cover piece be higher. This distance is between 10 and 50 cm, preferably between 15 and 35 cm, and here precisely 20 cm.

This localized attachment of the cover piece by each clip is operated without the intermediary of a profiled joint bead.

Each clip 7 is fixed to the inside face 22 of the window and extends in the centripetal direction beyond the edge 21 of the window. Each clip 7 is glued opposite the inner face 22 of the window.

The clip 7 comprises, seen in cross section, a base 70 located plumb under an inner edge of the window 2. This base 70 is under, and at least partially in contact with, the inner face 22 of the window. This base 70 is fixed to this inner edge of the window, and only to this inner edge, by means of a layer of glue 10 located in an outer hollow of the base 70; preferably the base 70 is not attached to the edge of the window, nor to the outer edge of the window, so that the clip fixing the cover piece to the window is as compact as possible.

The clip 7 further comprises, in the centripetal direction starting from the base 70:
- A base extension 71 located in the extension of the base 70 being further inside than the window 2; this base extension 71 has an outer surface 710 which is located further inside than the extension of the inner face 22 of the window, that is to say below and further inside than the edge 21 of said window 2, then
- a hooking portion 72 located in the extension of the base extension 70 being more outside than the base extension 70.

This attachment portion 72 has, at a centripetal end, a distal lateral boss 73 and at a centrifugal end a proximal lateral boss 73'.

The distal lateral boss 73 and the proximal lateral boss 73' are located opposite the edge 51 of the inner sheet of glass 5 and facing each other.

The attachment portion 72 has an outer surface 720 which is located opposite the edge 21 of the window 2; this outer surface 720 extends laterally without being further outside than the outer face 20 of the window, nor further inside than the inner face 22 of the window.

More specifically here, the outer surface 720 is located opposite the edge 41 of the interlayer sheet of plastic material 4.

Clip 7 presents in cross section the general shape of an n and a u which would be joined; the n forming the attachment portion 72.

The fixing of the cover piece to the glazing is carried out in the following way: the cover piece is brought closer above the hooking portion 72, then the distal lateral rib 64 comes to cover the distal lateral boss 73, in order to maintain mechanically the distal lateral rib against the distal lateral boss; this involves distal clipping of cover piece 6 onto clip 7.

In Figures 3 and 4, the cover piece 6 is attached to the clip 7 only by the clipping of the distal lateral rib 64 on the distal lateral boss 73. The proximal lateral rib 64' is not in contact with the proximal lateral boss 73'.

To improve the attachment of the covering part to the glazing, it is possible for the proximal lateral rib 64' to cover the proximal lateral boss 73', in order to mechanically maintain the proximal lateral rib against the proximal lateral boss; this involves proximal clipping of cover piece 6 onto clip 7.

To improve the attachment of the cover piece to the glazing, it is possible, in addition or instead, to provide an adhesive material 11, in the form of a layer of glue or an adhesive tape, located, in contact, between the inner face 62 of the cover piece 6 and the hooking portion 72, this adhesive material 11 preferably being positioned in an outer hollow 74 of the hooking portion 72.

The cover piece can be detached (unclipped) by performing the steps in reverse.

Each rib 64, 64' thus has an angle which serves as a support both in the outside-inside direction and both in a direction perpendicular to the outside-inside direction, for each lateral boss 73, 73'.

The shortest distance between the two ribs 64 and 64' is less than the width of the attachment portion 72.

Above the outer surface 710 of the base extension 71, towards the outside, a free space 18 is created between the edge 21 of the pane and the proximal lateral rib 64' of the cover piece 6.

The distal lateral rib 64 and the proximal lateral rib 64' comprise respectively a distal sealing lip 8 and a proximal sealing lip 8'; each sealing lip extends the full length of the cover piece. They each came from material or reported on the cover piece. In the case where a sealing lip is added, it is possible to provide that it has, in cross section, a bulb 80, 80', intended to be introduced into a corresponding housing, of identical hollow shape, made in the lateral rib.

The proximal sealing lip 8' is located in the free space 18.

The sealing lips are made of a flexible material for flexible contact with the adjacent element (body rebate for the distal sealing lip 8 and edge 21 of the glass for the proximal sealing lip 8').

As seen in Figure 4, for the management and control of the distance between the attachment portion 72 and a rebate 9 of adjacent body bay, it is possible to provide a spacer 12. This spacer 12 is located further 'inside that the attachment portion 72. It is integral with the clip 7 or glued to an inner face 722 of the attachment portion 72. It preferably has a length identical to that of the clip.

The outer face 60 of the cover piece 6 is located in the extension of the outer face 20 of the pane 2 in order to give an appearance close to flush. This makes it possible to limit the aerodynamic effects and in particular noise and resistance to penetration into the air. It is also a popular aesthetic appearance.

The cover piece 6 is in itself compact: the overall thickness e6 of the cover piece 6 is between 0.8 and 1.5 times the thickness e2 of the pane 2, or even is between 0, 9 and 1.2 times the thickness e2 of the pane 2; here, the thickness e6 is equal to the thickness e2.

The cover part 6 extends substantially in the extension of the window 2, that is to say that both the outer face 60 of the cover part 6 is located in the extension of the outer face 20 of the pane 2 and the inner end of the lateral ribs 64 and 64' does not extend further inside than the extension of the inner face 22 of the pane; thus, the overall thickness of the cover piece is low.

The clip 7 is particularly compact: the overall thickness e7 of the clip 7 is between 1.8 and 2.5 times the thickness e2 of the pane 2, or even is between 1.9 and 2.2 times the thickness e2 of pane 2; here, the thickness e7 is twice the thickness e2.
