Description

Sealing profile, in particular for glazing.

  The invention relates to a sealing profile made of an elastically deformable material, such as rubber, an elastomer or the like, intended in particular to ensure sealing between a

  glazing and a frame for supporting or holding the glazing.

  The mounting of such a profile at the angle of a glazing causes an extension of its radially outer part relative to the angle of the glazing and a compression and undulation of its radially inner part, which result in defects d and appearance. It was customary, to avoid these drawbacks, to make cuts at 45 'in the radially outer part of the profile at the angle of the glazing, which allowed the cut part of the profile to open on the entire corner. by reducing the compression of its internal part. It was however difficult to make these cuts precisely on the spot when mounting a profile on a glazing, hence a relatively small proportion.

  high of improperly installed, improperly cut or discarded profiles.

  These drawbacks could have been avoided or eliminated by a technique proposed by the Applicant in its Patent FR-2 708 308, which consists in forming the radially outer part of the profile, over its entire length, with perforations, cuts or partial notches which facilitate extending this part to the corners of the glazing without affecting the mechanical strength of the

  profile or sealing on the glazing.

  However, the profiles which are currently used for sealing a glazing on a frame, have retained shapes which were originally chosen to reduce the aforementioned drawbacks of mounting the profiles at the corners of the glazing while ensuring sealing minimal on glazing,

  often at the expense of aesthetics.

  The present invention relates to a new sealing profile, in particular for glazing, which makes it possible both to improve the sealing and the aesthetics and to avoid the drawbacks linked to its mounting to the

angles of a glazing.

  It proposes, for this purpose, a sealing profile made of elastically deformable material, in particular for glazing, comprising a first part intended to be mounted in the interval between a glazing and a glazing holding frame, an intermediate part s' extending at the edge of the frame and a third part or visible part extending over the glazing outside the frame, characterized in that the intermediate part of the profile comprises, on its face facing the glazing, a tubular lip, compact or cell or a cell mass that is covered

  by the third part of the profile.

  This profile differs from most of the profiles previously known in that it comprises, not a simple sealing lip, but a tubular, compact or cellular lip or a cellular mass which makes it possible to ensure better sealing on the glazing and in that this lip or this mass is formed not on the radially inner or visible part of the profile, but on an intermediate part which is at the edge of the frame and which is not visible, this

  which greatly improves the aesthetics.

  The fact that the lip or the cell mass is formed at the level of the neutral fiber of the profile makes it possible not to degrade the seal at the corners of the glazing. The third part of the profile is thin and forms a transverse tongue intended to

apply to the glazing.

  This third part of the profile, which constitutes the visible part of the profile when the latter is mounted in place between the frame and the glazing, completely masks and protects the lip or the sealing cellular mass formed on the intermediate part of the profile and has itself a small thickness to be as visible as possible relative to the frame and

  to increase the "clear glass".

  According to yet another characteristic of the invention, this tongue constitutes a stop on which the vertex of the lip or cell mass can rest. This tab therefore has the additional function of reducing the deformations of the lip or cell mass which could occur along the profile. Advantageously, the first part of the profile comprises, opposite the third part of the profile, a curved longitudinal lip and a lip

  transverse application on the glazing.

  These two lips respectively facilitate the introduction of the profile between the frame and the glazing and improve and complete the seal on

glazing.

  Finally, the first part of the profile has perforations, cutouts or partial notches which promote its extension at the corners of the glazing, reducing the compression of the third part of the profile. The invention will be better understood and other characteristics, details and advantages thereof will appear more clearly on reading the

  description which follows, given by way of example in

  reference to the accompanying drawings in which: - Figure 1 schematically shows the cross-sectional shape of a profile according to the invention, in the free state; - Figure 2 schematically shows the cross-sectional shape of this profile, mounted on a

  frame for supporting or supporting a glazing.

  The profile 10 according to the invention, a preferred embodiment of which is shown in the drawings, comprises a first part 12 intended to be housed in the gap between a glazing unit 14 and a frame 16 for supporting or holding this glazing unit, a second part or intermediate part 18 for attachment to a flange of the frame, and a third part 20 which constitutes the visible part of the profile when the latter is mounted in place

between a frame and a glazing.

  The profile 10 is fixed to the frame 16 by engaging a groove 22 formed in the face of the intermediate part 18 opposite the glazing 14 on a transverse edge of the frame 16 oriented towards the

glazing.

  The other face of the profile, facing the glazing, comprises at the intermediate part 18 a tubular lip 24 of approximately V section with a concave wall and a convex wall (sometimes called a shark fin) the top of which is oriented towards the glazing 14 and at least one wall 26 of which has longitudinal undulations 28 improving its flexibility. The third part 20 of the profile is a transverse tongue 30 which, on one side, forms a wall delimiting the groove 22 for attachment to the frame 16 and which, on the other side, extends above the lip

  tubular 24 being slightly spaced therefrom.

  The first part 12 of the profile comprises, opposite the third part 20, a curved lip 32 which extends on the side of the frame 16 and a transverse lip 34 which extends on the opposite side in the direction of the glazing 14

for sealing purposes.

  For its mounting in place between a glazing 14 and its support or holding frame 16, the profile 10 is pushed in between the frame and the glazing, as indicated by the arrow F in FIG. 2, the curved lip 32 of its first part 12 facilitating the positioning of the profile, while the transverse lip 34 flexes slightly upwards as shown in FIG. 2 and provides a seal on the

glazing 14.

  When the profile 10 is in place, the groove 22 having been engaged on the transverse rim of the frame 16, the tubular lip 24 of the profile is compressed elastically on the glazing 14, its top rising slightly upwards as shown in FIG. 2 and the transverse tongue 30 of the third part 20 of the profile is also applied elastically to the glazing 14, completely masking the tubular lip 24. In addition, this tongue 30 constitutes a stop for the top of the tubular lip 24, which would tend to go back upwards in FIG. 2. As the deformation of the tubular lip 24 is blocked by the tongue 30 in the direction parallel to the glazing, this deformation can only occur perpendicular to the glazing 14, which improves and

  reinforces the application of the lip 24 on the glazing 14.

  As can be clearly seen in FIG. 2, when the sealing profile 10 is in place between the glazing 14 and the frame 16, the sealing is ensured on the glazing 14 at three different levels, by the lip 34 of the first part of the profile, by the tubular lip 24 of the second part of the profile and by the

  transverse tongue 30 of the third part of the profile.

  The seal on the frame 16 is ensured by the curved lip 32 of the first part of the profile and

  by the groove 22 engaged on the edge of the frame 16.

  The profile according to the invention therefore makes it possible to considerably improve the seal between the glazing and the frame, while reducing the visible part of the profile (the transverse tongue 30 may be of very small thickness), which consequently increases the clear glazing (the useful part of the glazing 14 relative to the frame 16), the aesthetics being ensured by the lip 30 which completely masks the tubular lip 24, prevents the latter from being irregularly deformed and has a very clear appearance and very regular even at

glazing angles.

  The first part 12 of the profile has perforations, cuts or partial cuts 36 over its entire longitudinal extent, these perforations, cuts or partial cuts being formed substantially up to the level of the line 38 shown in dotted lines in FIG. 1, which allows the first part 12 of the profile or radially external part thereof to open fairly widely at the corners of the glazing, thereby reducing the compressive stresses of the third part 20 of the profile. The presence of these perforations, cutouts or partial cuts in the first part of the profile improves the behavior of the profile as a whole at the corners of the glazing and promotes the regularity and uniformity of appearance of the visible part of the profile on the sides.

  rectilinear glazing and angles thereof.

  In an alternative embodiment of the invention, the tubular lip 24 which is formed from the same material as the rest of the profile, can be replaced by a lip or by a bead having substantially the same shape or a different shape, for example cylindrical , which is tubular or solid and made of cellular material and which constitutes a mass of compressible material. This cell mass easily deforms and crashes on the glazing 14 when it is applied thereto, ensuring good sealing. It is covered and protected by the tongue 30 of the third part of the profile and therefore does not risk being damaged during the positioning of the profile or later.
