Description

Technical field of the invention

[0001] The present invention relates to the general field of roller shutters or similar devices such as, for example, sunshades. More specifically, it relates to the rails, conventionally called tracks, which guide the roller shutter or similar device during its opening or closing. State of the art

[0002] Building openings are frequently equipped with roller shutters or similar devices that allow them to be closed or opened. These roller shutters or similar devices consist of a rotating shaft coupled to a curtain or fabric that can be wound around the shaft or unwound to respectively open or close the corresponding opening; the winding and unwinding are achieved by rotating the shaft in one direction or the opposite direction.

[0003] In the case of roller shutters, the curtain is generally composed of multiple slats extending parallel to the axis of the roller tube and hinged to one another. These slats are typically curved to facilitate the curtain's rolling around the tube. The lateral ends of the curtain slats are generally engaged in tracks, commonly called guides, whose cross-section is generally U-shaped. These guides allow the lateral ends to be guided during the opening and closing of the roller shutter curtain, ensuring the correct positioning of the curtain during and after its movement. These guides also prevent any lateral intrusion when the roller shutter is closed.

[0004] In the case of sunshade screens, the fabric is joined by its lower edge to a rim whose lateral ends also engage inside the tracks and are arranged so as not to come out of them, the latter allowing to guide said lateral ends during the opening and closing of the sunshade screen fabric, so as to guarantee the correct positioning of the fabric during and after its movement.

[0005] For obvious reasons of ease of maintenance of the apron or canvas, each track is advantageously composed of several metal profiles, for example in aluminum alloy, assembled together by interlocking and secured tightly together preferably by screws, advantageously not visible.

[0006] Such metal profiles are also described in international patent application WO 2020 / 165809.

[0007] These profiles are manufactured, in the conventional manner, by extrusion. In this case, it is understandable that the profiles may have dimensions that vary over time, because the extrusion dies have tolerances that can also vary over time due to wear and dimensional changes.

[0008] Furthermore, these profiles generally receive at least one initial powder coating, followed by one or more additional coats in the case of overcoating. These additional coats are necessary when the manufacturing site is not equipped with a powder coating booth, or when the profiles must be painted in a non-standard color. It is clear that these varying coating thicknesses also influence the dimensional variations of the profiles.

[0009] It is clear that these dimensional variations are detrimental because, on the one hand, the correct positioning of the profiles relative to each other is no longer ensured regardless of the method of assembly of said profiles (interlocking or screw fastening) and, on the other hand, the guidance of the roller shutter or similar by the tracks is no longer optimal, which can result in a lack of sealing and / or a decrease in the quality of blackout or sun protection. Summary of the invention

[0010] The aim of the present invention is therefore to provide a guide rail for a roller shutter or similar device, composed of a plurality of profiles assembled together, which limits the relative movement of one profile with respect to another, while ensuring that the profiles remain securely connected and compensating for dimensional variations in said profiles. Furthermore, the guide rail according to the invention also eliminates or conceals the screws that fasten the profiles together, thus ensuring the aesthetic appearance of the guide rail.

[0011] According to the invention, a guide rail is therefore proposed for guiding a roller shutter or similar device used to close or, conversely, open an opening in a building recess, said guide rail comprising at least: a main profile arranged to be fixed on a vertical face of said embrasure and forming one of the longitudinal edges of a guide slot, a removable profile cooperating in a functional position with said main profile to form the other longitudinal edge of the guide slot, and a locking profile suitable for cooperating with the main profile and the removable profile to maintain said removable profile in its functional position and / or to conceal the mechanical coupling areas of said main and removable profiles, said slide being notable in that it comprises an elastically deformable clamping member removably attached to the removable profile and being shaped to exert pressure on the locking profile so as to ensure the cooperation of said locking profile with the main profile and the removable profile.

[0012] It is clear that the pressure exerted by the clamping element on the locking profile ensures that the locking profile cooperates well with the main profile and the removable profile, in particular to maintain the removable profile in its functional position.

[0013] The main profile advantageously has a cross-section in the general shape of a G rotated 90° to the left and comprises at least a first flat wing and a second wing, the latter being generally parallel to each other and extending in the same direction, a web connecting said first and second wings together and being arranged to be applied by its external face to said associated vertical face of the embrasure, and an internal wing extending generally perpendicularly from said web and towards the interior of the slide.

[0014] The said inner wing is generally L or T shaped so as to have at least one part globally parallel to the web of the main profile and oriented in the direction of the first wing.

[0015] The removable profile advantageously has a cross-section in the general shape of an inverted Z and comprises a first and a second flange that are generally parallel to each other and extend in opposite directions, a web connecting said first and second flanges together, and an outer flange extending generally perpendicularly from the web of said removable profile and parallel to said first flange and in the same direction as the latter.

[0016] Preferably, the first wing of the removable profile has a cross-section in the general shape of an asymmetrical U rotated 90° to the right, said first wing being arranged so that the shorter part of the U is located on the inside side of the slide and forming a longitudinal groove opening out at each of the longitudinal ends of said first wing and on the side of the second wing and a bearing area extending along the free edge of said part of the first wing.

[0017] Advantageously, the blocking profile has a cross-section in the general shape of an L rotated 90° to the right and comprises at least a first and a second flanges globally perpendicular to each other, a first rim originating from the free edge of the first flange and extending globally parallel to the latter towards the inside of the slide, and a second rim extending globally perpendicular to the free edge of the second flange towards the inside of the slide.

[0018] Preferably, said second rim being arranged so that the shorter part of the J is oriented towards the outside of the slide.

[0019] Advantageously, the clamping member is generally in the form of an angle bracket and comprises a first wing and a second wing provided with a longitudinal slot opening at each of its longitudinal ends and at the right of the free edge of said second wing, and an external fin extending generally perpendicularly from said second wing in a direction opposite to the first wing.

[0020] The outer fin advantageously has an internal groove arranged on its face located on the side opposite the first fin and being able to cooperate with the part of the second edge of the locking profile.

[0021] According to one embodiment, the first wing has a flange extending along the edge of the part of its first wing opposite the support area, said flange being generally U-shaped so as to form a second longitudinal groove opening out at each of the longitudinal ends of said first wing and on the side of the second wing, and the blocking profile also has an internal wing extending globally perpendicularly from the first wing and into the inside of the slide, and having a cross-section generally L-shaped or T-shaped so as to have at least one part globally parallel to the first wing and oriented in the direction of the first flange.

Description of the implementation methods

[0023] On the figures 1 to 4A guide rail 1, according to the invention, is shown for guiding a roller shutter or similar device used to close or open an opening, for example a door or window, located in a recess of a building (not shown). The guide rail 1 is fixed vertically, in the conventional manner, to one of the faces of the recess. It is understood that the guide rail 1 can also be fixed horizontally or at a greater or lesser angle to one of the faces of the recess, without departing from the scope of the present invention. In such cases, terms such as horizontal, vertical, lower, or upper should be adapted accordingly.

[0024] Said slide 1 comprises at least four elements, namely: a main profile 2 arranged to be applied to a vertical face of said embrasure and forming one of the longitudinal edges of a guide slot 3, a removable profile 4 cooperating in a functional position with said main profile 2 to form the other longitudinal edge of the guide slot 3, a locking profile 5 suitable for cooperating with the main profile 2 and the removable profile 4 to maintain said removable profile 4 in its functional position and / or to conceal the mechanical coupling areas of said main profile 2 and removable profile 4, and an elastically deformable clamping member 6 removably attached to the removable profile 4 and being shaped to exert pressure on the locking profile 5 so as to ensure its cooperation with the main profile 2 and the removable profile 4.

[0025] The areas of the main profile 2 and removable profile 4 that cooperate with each other to maintain the removable profile 4 in its functional position are referred to here as "mechanical coupling zones".

[0026] The said main profile 2 has a cross-section in the general shape of a G rotated 90° to the left and comprises at least a first flat wing 21 and a second wing 22, the latter being globally parallel to each other and extending in the same direction, a web 23 connecting said first and second wings 21, 22 to each other and being arranged to be applied by its external face to said associated vertical face of the embrasure, and an internal wing 24 extending globally perpendicularly to said web 23 and towards the interior of the slide 1.

[0027] Here, "internal" refers to elements or parts of elements oriented or arranged towards and inside the slide 1, and "external" refers to elements or parts of elements oriented or arranged towards and outside said slide 1.

[0028] Similarly, here we designate as "globally perpendicular(ly)" and "globally parallel(ly)" elements or parts of elements making an angle between them respectively between 70° and 110° and an angle between -20° and +20°.

[0029] For obvious reasons of mechanical resistance and in the case of particular uses of the slide 1 according to the invention, the cross-section of the second wing 22 is advantageously in the general shape of an asymmetrical U rotated by 180°, said second wing 22 being arranged so that the shorter part 25 of the U is located inside the slide 1 and oriented towards said inside, said part 25 of the second wing 22 then forming one of the longitudinal edges of the guide slot 3 of the slide 1.

[0030] Similarly, the cross-section of said inner wing 24 is advantageously in general L or T shape so as to have at least one part 26 globally parallel to the web 23 of the main profile 2 and oriented in the direction of the first wing 21.

[0031] Said removable profile 4 has a cross-section in the general shape of an inverted Z and comprises a first and a second wing 41, 42 which are generally parallel to each other and extend in opposite directions, and a web 43 connecting said first and second wings 41, 42 to each other.

[0032] The first wing 41 of the removable profile 4 has a cross-section advantageously in the general shape of an asymmetrical U rotated 90° to the right, said first wing 41 being arranged so that the shorter part 44 of the U is located on the inside side of the slide 1 and forming a longitudinal groove 45 opening out at each of the longitudinal ends of said first wing 41 and on the side of the second wing 42 and a bearing area 46 extending along the free edge of said part 44 of the first wing 41.

[0033] For obvious reasons of mechanical resistance and in the case of particular uses of the slide 1 according to the invention, the cross-section of said second wing 42 is advantageously in the general shape of a J rotated 90° to the left so that the shorter part 47 of the J is located inside the slide 1 and oriented towards said inside, said part 47 of the second wing 42 then forming the other longitudinal edge of the guide slot 3 of the slide 1.

[0034] The said removable profile 4 further comprises an external wing 48 extending globally perpendicularly from the web 43 of said removable profile 4 and parallel to said first wing 41 and in the same direction as the latter, that is to say towards the outside of the slide 1.

[0035] The locking profile 5 has a cross-section in the general shape of an L rotated 90° to the right and comprises at least a first and a second wing 51, 52 globally perpendicular to each other, a first rim 53 originating from the free edge of the first wing 51 and extending globally parallel to the latter towards the interior of the slide 1, and a second rim 54 extending globally perpendicular to the free edge of the second wing 51 towards the interior of the slide 1.

[0036] For obvious reasons of mechanical resistance and in the case of a particular configuration of the clamping member 6 described later, the cross-section of said second rim 54 is advantageously in the general shape of J, said second rim 54 being arranged so that the shorter part 55 of the J is oriented towards the outside of the slide 1.

[0037] The clamping member 6 of the slide 1 is generally angle-shaped and comprises a first, substantially vertical, flange 61 and a second, substantially horizontal flange 62, having a longitudinal slot 63 opening at each of its longitudinal ends, as well as at the free edge of said second flange 62. The clamping member 6 further comprises an external fin 64 extending generally perpendicularly from said second flange 62 in a direction opposite to the first flange 61. This external fin 64 advantageously comprises an internal groove 65 formed on its face located on the side opposite the first flange 61.

[0038] With the configuration described above and with reference to figures 2 to 4 To assemble the slide 1 according to the invention, the following procedure is used.

[0039] First, the main profile 2 is put in place by applying the external face of its core 23 to the associated vertical face of the opening of the building, then the said main profile 2 is fixed, in a conventional manner, to the frame associated with the said opening by any suitable means such as, for example, screws.

[0040] Next, the removable profile 4 and the main profile 2 are made to cooperate in order to place said removable profile 4 into its functional position, namely when said removable profile 4 and main profile 2 form the guide slot 3. To do this, the removable profile 4 is moved, according to the arrow of the figure 2 , in such a way as to engage its longitudinal groove 45 on the part 26 of the inner wing 24 of the main profile 2 until its bearing area 46 comes into contact with said inner wing 24 of the main profile 2.

[0041] Next, the clamping element 6 is secured to the slide 1 on the removable profile 4. To do this, the clamping element 6 is moved according to the arrow of the figure 3 , in such a way as to engage its longitudinal slot 63 on the outer wing 48 of the removable profile 4 until its first wing 61 comes into contact with the first wing 41 of said removable profile 4.

[0042] Finally, the locking profile 5 is put in place so that it cooperates with the main profile 2 and the removable profile 4 to hold the latter in its functional position. To do this, the locking profile 5 is moved according to the arrows of the figure 4, so as to simultaneously engage its first rim 53 between the first wings 21, 61 respectively of the main profile 2 and of the clamping member 6, and its second rim 54 between the outer fin 64 of the clamping member 6 and the web 43 of the removable profile 4 until the part 55 of said second rim 54 comes to be inserted into the internal groove 65 of said outer fin 64.

[0043] A person skilled in the art will have no difficulty in dimensioning the clamping member 6, on the one hand, to allow the installation of the locking profile 5 and, on the other hand, so that the clamping member 6 exerts pressure on the locking profile 5 in such a way as to guarantee its cooperation with the main profile 2 and the removable profile 4.

[0044] According to a preferred embodiment, the clamping member 6 has a length less than that of the slide 1 so as to be able to adjust the value of the pressure exerted on the locking profile 5 by adapting the number of clamping members 6 put in place along said slide 1 according in particular to the length of the latter.

[0045] On the figures 5 and 6 , a variant embodiment of the slide 1, according to the invention, is shown, namely a slide 11 for guiding a roller shutter or similar used to close or on the contrary open an opening, for example of the type door or window, arranged in a recess of a building not shown, said slide 1 being fixed vertically, in a conventional manner, on one of the faces of said recess.

[0046] Like the slide 1 described previously, said slide 11 comprises at least four elements, namely: a main profile 12 arranged to be applied to a vertical face of said embrasure and forming one of the longitudinal edges of a guide slot 13, a removable profile 14 cooperating in a functional position with said main profile 12 to form the other longitudinal edge of the guide slot 13, a locking profile 15 adapted to cooperate with the main profile 12 and the removable profile 14 to hold said removable profile 14 in its functional position and / or to mask the mechanical coupling areas of said main profile 12 and removable profile 14, and an elastically deformable clamping member 16 removably attached to the removable profile 14 and being shaped to exert pressure on the locking profile 15 so as to guarantee its cooperation with the main profile 12 and the removable profile 14.

[0047] The said main profile 12 has a cross-section in the general shape of a G rotated 90° to the left and comprises at least a first flat wing 121 and a second wing 122, the latter being globally parallel to each other and extending in the same direction, a web 123 connecting said first and second wings 121, 122 to each other and being arranged to be applied by its external face to said associated vertical face of the embrasure, and an internal wing 124 extending globally perpendicularly to said web 123 and towards the interior of the slide 11.

[0048] Similarly, the cross-section of said inner wing 124 is advantageously in general L or T shape so as to have at least one part 125 globally parallel to the web 123 of the main profile 12 and oriented in the direction of the first wing 121.

[0049] Said removable profile 14 has a cross-section in the general shape of an inverted Z and comprises a first and a second wing 141, 142 which are generally parallel to each other and extend in opposite directions, and a web 143 connecting said first and second wings 141, 142 to each other.

[0050] The first wing 141 of the removable profile 14 has a cross-section advantageously in the general shape of an asymmetrical U rotated 90° to the right, said first wing 141 being arranged so that the shorter portion 144 of the U is located on the inside of the slide 11, and forming a first longitudinal groove 145 opening onto each of the longitudinal ends of said first wing 141 and onto the side of the second wing 142. Said portion 144 of the first wing 141 has a bearing area 146 extending along its free edge and a flange 147 extending along its other edge opposite the bearing area 146, said flange 147 being in the general shape of a U so as to form a second longitudinal groove 148 opening onto each of the longitudinal ends of said first wing 141 and onto the side of the second wing 142.

[0051] The said removable profile 14 further comprises an external wing 149 extending globally perpendicularly from the web 143 of said removable profile 14 and parallel to said first wing 141 and in the same direction as the latter, that is to say towards the outside of the slide 11.

[0052] The locking profile 15 has a cross-section in the general shape of an L rotated 90° to the right and comprises at least a first and a second wing 151, 152 globally perpendicular to each other, a first flange 153 originating from the free edge of the first wing 151 and extending globally parallel to the latter towards the interior of the slide 11, and a second flange 154 extending globally perpendicular to the free edge of the second wing 151 towards the interior of the slide 11.

[0053] For obvious reasons of mechanical resistance and in the case of a particular configuration of the clamping member 6 described later, the cross-section of said second rim 154 is advantageously in the general shape of J, said second rim 154 being arranged so that the shorter part 155 of the J is oriented towards the outside of the slide 1.

[0054] Finally, the locking profile 15 also includes an internal wing 156 extending globally perpendicularly from the first wing 151 and towards the inside of the slide 11. The cross-section of said internal wing 156 is advantageously in the general shape of L or T so as to have at least one part 157 globally parallel to the first wing 151 and oriented towards the first rim 153.

[0055] The clamping member 16 of the slide 11 is identical to the clamping member 16 of the slide 1 described previously. Thus, the clamping member 16 is generally angle-shaped and comprises a first, substantially vertical, flange 161 and a second, substantially horizontal flange 162, each having a longitudinal slot 163 opening at each of its longitudinal ends, as well as at the free edge of said second flange 162. The clamping member 16 further comprises an external fin 164 extending generally perpendicularly from said second flange 162 in a direction opposite to the first flange 161. This external fin 164 advantageously has an internal groove 165 formed on its face located on the side opposite the first flange 161.

[0056] With the configuration described above and with reference to figures 5 and 6 To assemble the slide 11, proceed as described below.

[0057] First, the main profile 12 is put in place by applying the external face of its core 123 to the associated vertical face of the opening of the building, then the said main profile 12 is fixed, in a conventional manner, to the frame associated with the said opening by any suitable means such as, for example, screws.

[0058] Next, the removable profile 14 and main profile 12 are made to cooperate to place said removable profile 14 in its functional position, namely when said removable profile 14 and main profile 12 form the guide slot 13. For this, the removable profile 14 is moved so as to engage its first longitudinal groove 145 on the part 125 of the inner wing 124 of the main profile 12 until its bearing area 146 comes into contact with said inner wing 124 of the main profile 12.

[0059] Subsequently, the clamping member 16 of the slide 11 is secured to the removable profile 14. To do this, the clamping member 16 is moved so as to engage its longitudinal slot 163 on the outer wing 149 of the removable profile 14 until its first wing 161 comes into contact with the first wing 141 of said removable profile 14.

[0060] Finally, the locking profile 15 is put in place so that it cooperates with the main profile 12 and the removable profile 14 to hold the latter in its functional position. To do this, the locking profile 5 is moved according to the arrows of the figure 5 , in a way that engages simultaneously; its first rim 153 against the inner face of the first wing 121 of the main profile 12, the part 157 of its inner wing 156 in the second longitudinal groove 148 of the rim 147 of the removable profile 14 so that the inner face of said part 157 is in contact with the outer face of the first wing 161 of the clamping member 16, and its second rim 154 between the outer fin 164 of the clamping member 16 and the web 143 of the removable profile 14 until the part 155 of said second rim 154 is inserted into the inner groove 165 of said outer fin 164.

[0061] A person skilled in the art will have no difficulty in dimensioning the clamping member 16, on the one hand, to allow the installation of the locking profile 15 and, on the other hand, so that the clamping member 16 exerts pressure on the locking profile 15 in such a way as to guarantee its cooperation with the main profile 12 and the removable profile 14.

[0062] According to a preferred embodiment, the clamping member 16 also has a shorter length than the slide 11 so as to be able to adjust the value of the pressure exerted on the locking profile 15 by adapting the number of clamping members 16 placed along said slide 11 according in particular to the length of the latter.

[0063] With the configurations described above, it is clear that by covering all parts of the main profile 2,12 and removable profile 4,14 and of the clamping member 6,16 located on the left side of the slide 1,11 (i.e. on the opposite side to the slot 3,13), each locking profile 5,15 cooperates with the main profile 2,12 and the removable profile 4,14 to also conceal the mechanical coupling areas of said main profiles 2,12 and removable profiles 4,14 as well as any screws, not shown, securing the main profile 12 and removable profile 14 together.

[0064] Thus, with reference in particular to figures 5 and 6 Regarding the slide 11, the removable profile 14 is placed on the main profile 12 and then secured to the latter by means of a plurality of screws V. Next, the clamping member 16 is placed on the removable profile 14. Finally, the locking profile 15 is put in place so that it cooperates with the main profile 12 and the removable profile 14. It is then clear that the locking profile 15 is advantageously shaped (cross-section in the general shape of an L rotated 90° to the right) to conceal the areas of mechanical coupling between the locking profile 15 and the aforementioned main profile 12 and removable profile 14 and clamping member 16, as well as the screws V securing the main profile 12 and removable profile 14. The same applies to the slide 1 described previously. This feature is interesting because it enhances the aesthetic appearance of the slide 1.11 according to the invention.

[0065] The slide 1,11 according to the invention finds a particular application for guiding a roller shutter or similar fitting an opening in a building.
