Description

The invention relates to an expandable finishing profile capable of fitting a

  roller shutter box or the like and intended to close a gap residing between a wall of said box and a wall, extending in a substantially parallel manner, corresponding to a frame which a construction for

the reception of this roller shutter.

  The present invention will find its application in the field of the manufacture of roller shutters intended to be installed in any construction, more particularly of a

dwelling.

  Such a roller shutter comprises, in a traditional manner, a box receiving, internally, the winding shaft of an apron and surmounting lateral slides inside

from which the latter parades.

  This rolling shutter is intended to be installed in a

  framing defined at the masonry level of a building.

  In order to ensure such an installation, it is essential to provide a certain spacing between said frame and said roller shutter, this spacing remaining after the final installation of the latter. In this regard, it will be noted that the presence of this spacing poses, on the one hand, a sealing problem resulting from air circulation between the outside and the inside of the building and, on the other hand, a thermal as well as acoustic insulation problem. In addition, it will be observed that, on the internal side of the building, said spacing turns out to be unattractive so that it is customary to conceal it by means of a

finishing profile or the like.

  Several types of finishing profiles are already known, some of which are in the form of a strip

  while others are defined by an angle.

  In the case of a blade, the latter can, for example, be inserted into a groove formed, perpendicularly, in the upper wall of the box, when the latter projects beyond the rear of the masonry. In fact, it will be observed that such a groove is produced during the manufacturing process of the box.

2 2792361

  so that it is essential to ensure its positioning in a particularly precise manner at the level of said upper wall so that the blade, intended to be inserted therein,

  subsequently performs its function of finishing profile.

  When such a profile is defined by an angle iron, the latter can, for example, be glued directly to the upper wall of the box. On the latter can also be glued or welded one or more attachment tabs or the like intended to cooperate with such an angle. Again, the positioning of such a latch is made during the manufacture of the box which can cause, later, problems of alignment of the angle with the masonry during

of its implementation on site.

  In addition, it should be observed that, very often, said angle iron is not made of the same material as that of said box so that their aging, over time, is not

not uniform.

  It should also be noted that the wall of the frame has, often and over at least part of its length, a deformation so that the spacing between the frame and the box is in no way uniform. One solution then consists in choosing an angle iron comprising a wing of suitable width from a set of angles of various dimensions. It is therefore essential to have a greater or lesser number of

these angles.

  In addition, it will be observed that, when the rear wall of the box is situated substantially in the extension of the masonry or the like, the installation of an angle iron proves to be difficult and this

  whatever the size and shape of it.

  Finally, it will also be noted that such a finishing profile, if it effectively brings a solution to the aesthetic problem, does not make it possible to solve the problem of sealing so that it is, most often, supplemented by a joint

  sealing introduced inside said spacing.

3 2792361

  In this regard, it is essential that this seal, in particular defined by a strip of foam or the like, be in contact, on the one hand, with said finishing profile and, on the other hand, with masonry, this over the entire length of the gap, in order to guarantee sealing. However, it will be observed that the surface of said masonry is not always flat so that the distance between the wall of the box and that of the frame is not regular over the entire length of the spacing. Thus, despite the expandable nature of the seal, the latter

  is not always likely to guarantee a perfect seal.

  The present invention makes it possible to provide a solution to the aforementioned drawbacks through an expandable type finishing profile. To this end, the present invention relates to an expandable finishing profile suitable for equipping a roller shutter box or the like and intended to close a gap residing between a wall of said box and a wall, extending in a substantially parallel manner, corresponding to a frame that comprises a construction for the reception of this roller shutter, characterized in that it is in the form of an angle iron comprising a first wing and a second wing extending perpendicularly from the latter , at least one of these wings being, on the one hand, provided capable of coming to engage in said spacing, and, on the other hand, defined of an expandable nature and

adjustable in thickness.

  According to another characteristic, said wing engaged in the spacing comprises a base surmounted by a strip of a

expandable material.

  Another embodiment consists in that said engaged wing comprises, here again, a base, the latter being surmounted by a flexible longitudinal blade making an acute angle

with said base.

  Yet another embodiment consists in equipping such a base with a flexible accordion-like piece that can be cut at least

  at each fold that said flexible piece comprises.

4 2792361

  An additional characteristic relates to the fact that said base and, as the case may be, the strip of expandable material or the flexible blade define a superimposable elementary module, these superimposed modules being cut and / or separable individually. According to another characteristic, the second wing of said profile is defined capable of coming to bear against a second wall of the frame extending perpendicularly to a first wall of this frame, this first wall delimiting, with a wall

  of said box, the spacing in which the other wing engages.

  An additional characteristic concerns the fact that said

  second wing is of the type which can be cut longitudinally.

  According to another feature of the present invention, the base of each of the elementary modules comprises a second perpendicular wing extending in the direction of the base of the module.

  elementary immediately superimposed.

  In fact, this second wing is defined capable of coming to bear against a second wall of the frame extending perpendicularly to a first wall of this frame, this first wall delimiting, with a wall of said box,

  the spacing in which the other wing engages.

  Another characteristic of this second wing relates to the

  fact that it is of the type which can be cut longitudinally.

  In addition, a particularity of this second wing relates to the fact that it has, at its free end oriented towards the base of the immediately superimposed module, a

  chamfer intended to facilitate the fitting of said modules.

  The advantages of the present invention consist in that the finishing profile can be engaged between the frame and the box, this whatever the width and the profile of the spacing existing between them and their relative position. In particular and by its flexibility, said profile can follow the

curvature of the masonry.

  The presence of means of the expandable type advantageously allows immobilization of said finishing profile between the masonry and the box through a simultaneous bearing on the latter. Such a finishing profile constitutes an expandable sealing joint capable of limiting the circulation of air between the exterior and the interior of a building. Said profile also makes it possible to solve the problems of thermal insulation and

  acoustics mentioned above.

  Through the support of the second wing of such a profile, the spacing is completely obscured, thus contributing to

  improving the aesthetics of the roller shutter.

  Other objects and advantages of the present invention

  will appear during the description which follows relating to

  to embodiments which are given only by way of examples

indicative and not limiting.

  Understanding this description will be facilitated by

  The present invention relates to the field of manufacturing roller shutters intended to equip a door, window or the like, the assembly formed by the latter and said roller shutter 1 being intended to be installed at a defined frame 2

6 2792361

  in a construction, in particular of a dwelling, such a frame 2 being, for example delimited by the masonry 3,

  possibly supplemented by an insulator.

  In fact and as shown in Figures 1 and 2, said masonry 3 is defined, in part, in the form of a slab 4 below which extends a lintel 5 having a bottom wall 6, said lintel 5 being, optionally , supplemented by a fallout of

lintel 7.

  With regard to said roller shutter 1, the latter traditionally takes the form of a box 8 receiving, internally, the winding shaft of an apron capable of scrolling

  in lateral slides 9 surmounted by said box 8.

  Such a box 8 is constituted by the assembly of a sub-face oriented in the direction of the slides 9, a rear wall 11 directed towards the interior of the building, an upper wall 12 oriented in the direction of the lintel 5 and of a front wall 13, the latter being directed towards the outside of the building and coming to be positioned, where appropriate, at the rear of said fallout

lintel 7.

  In fact and as shown in Figures i and 2, during its installation, said box 8 is positioned, at the level of the frame 2, at a certain distance from the latter, so that, between a wall 8A of said box 8 and a wall 2A of said frame 2 extending substantially parallel to this

  last 8A, there is a spacing 14.

  It is, more particularly, at the level of the last 14 that said box 8 of rolling shutter i is completed by a profile of

  finish 15 able to close said space 14.

  According to the invention, said finishing profile 15 is of an expandable nature and is in the form of an angle 16 comprising a first wing 17 and a second wing 18 extending perpendicularly from the latter 17. At least one of these wings 17, 18 is, on the one hand, provided capable of coming to engage in said spacing 14, and, on the other hand, defined

  expandable and adjustable in thickness.

7 2792361

  Thus, according to a first embodiment shown in FIG. 3, the wing 17 of the finishing profile 15 intended to be engaged in said spacing 14 comprises a base 19 surmounted by a band 20 defined in material of the expandable type. It is, more particularly, the latter which can come to bear against the wall of said frame 2 when said finishing profile 15 is

engaged in said spacing 14.

  In fact, such a base 19 is capable of defining, in combination with such a strip 20, an elementary module 21 of the superimposable type. Thus and as shown in Figures 4 and 8, said wing 17 is constituted by a superposition of a number of these elementary modules 21, 21 ', 21' 'which are defined as type

  can be cut and / or separated individually.

  It follows that, by removing one or more of these elementary modules 21, 21 ', 21' ', it is possible to give said wing 17 a thickness suitable for closing said spacing 14, in particular after crushing and expansion of said wing 17 inside the latter. This allows, in particular, said wing 17 to match the curvature of the wall 2A of the frame 2 and, thus, to guarantee both the tightness and the insulation.

thermal and acoustic.

  According to another embodiment shown in FIG. 5, the wing 17 intended to be engaged in said spacing 14 comprises a base 19 surmounted by a flexible longitudinal blade 22 making an acute angle with said base 19. It is, more particularly, such a flexible blade 22 or, as the case may be, a final blade 23 equipping the latter, which is intended to bear against

the wall 2A of the frame 2.

  In fact, such a base 19 is capable of defining, in combination with said flexible blade 22, an elementary module 21 which can be superposed. Thus and as shown in FIGS. 6 and 9, said wing 17 is constituted by a superposition of a number of these elementary modules 21, 21 ', 21' 'which are defined of the type which can be cut and / or separated individually, in particular at the level

  of each of the flexible blades 22, 22 ', 22' '.

8 2792361

  Another embodiment of such a finishing profile 15 is shown in FIG. 7, the wing 17 of which, intended to be engaged in said spacing 14, comprises a base 19 supplemented by a flexible accordion part 24 having a number of folds 25 forming an acute angle between them. It is, more particularly, at each of these folds 25 that said flexible part is defined capable of being cut in order to adjust the thickness of said wing 17 to the height of the spacing 14, in particular after crushing

  and expansion of said finishing profile 15.

  According to another characteristic of the present invention and as visible in FIGS. 2 to 7, said finishing profile 15 comprises a second wing 18, perpendicular to that 17 engaged

  in the spacing 14, and defined by a blade 26.

  In this regard and as shown in Figures 1 and 2, said spacing 14 is delimited, on the one hand, by a first wall 2A of said frame 2 and, on the other hand, by a wall 8A of the box 8 extending so substantially parallel to said first wall 2A of this frame 2. The latter comprises, extending perpendicular to said first wall 2A of this frame 2, a second wall 2B against which said blade

  26 is defined capable of coming to bear.

  Said blade 26 is preferably of the type which can be cut longitudinally in order to allow an adjustment of its

  width depending, for example, on the proximity of the slab 4.

  To return to the embodiments for which said finishing profile 15 comprises a superposition of elementary modules 21, 21 ', 21' ', each base 19, 19', 19 '' of the latter can, as shown in FIGS. 8 and 9, to be completed by a second wing 27, 27 ', 27' '. This is perpendicular to said base 19, 19 ', 19' 'and extends towards the base

  19 ', 19' 'of the elementary module 21', 21 '' immediately superimposed.

  It will be noted that, in such a case, said elementary modules 21, 21 ′ as well as, as the case may be, the strip 20 or the flexible blade 22 of the latter, are defined to be of a cutable nature.

and / or separable.

  Such an embodiment makes it possible, on the one hand, to adjust the thickness of the finishing profile 15 by removing one or more of these elementary modules 21, 21 ', 21' ', such a profile 15 can then be fully engaged in the spacing 14 without emerging from it, if only in part, as visible in FIG. 1. However, it will be observed that said wing 27 can still be defined capable of coming to bear against the second wall 2B of the frame 2. In such a case, the strip 20 or the flexible blade 22 of the elementary module 21 situated at the upper end 28 of said profile 15 is capable of coming to bear against the first wall 2A of said frame 2 which makes it possible to guarantee the sealing and insulation at the spacing 14. Knowing that said strip 20 and the flexible blade 22 are cut and / or separable, it is also possible to bring the base 19 into

  applies against said first wall 2A of the frame 2.

  According to another characteristic of this wing 27, 27 ', 27' ', the latter is advantageously of the type which can be cut longitudinally. This allows, in particular, to said profile 15 to be completely engaged in the spacing 14 and to press, as the case may be, said strip 20 or said flexible blade 22, directly and sealingly, against said first wall 2A of said frame

  2, after removal of said wing 27.

  As shown in Figures 8 and 9, this second wing 27, 27 ', 27' 'has, at its free end 31 oriented towards the base 19', 19 '' of the module 21 ', 21' ' at once

superimposed, a chamfer 32.

  The latter is intended to facilitate the fitting of said modules 21, 21 ', 21' 'during the crushing of said profile 15 to

  during its installation at the spacing 14.

  Thus, the present invention relates to a finishing profile 15 capable of being engaged in the space 14 residing between a wall 2A of the frame 2 of a construction and that 8A of a box 8. In this regard, it will be observed that such a profile 15 can be disposed at the upper wall 12, the front wall 13

2792361

  or at any of the side walls of said

box 8.

  This finishing profile 15 not only provides a solution to the problem of the tightness of the box 8 but also to the problem of the aesthetics of the latter as well as its insulation.

thermal and acoustic.
