Description

Title of the invention: Roller shutter box having a passage comprising at least one insulation element Technical field of the invention

[0001] The present invention relates to the technical field of roller shutter boxes. State of the art

[0002] A roller shutter classically comprises a roller shutter box into which is attached at least one curtain which is formed of an assembly of slats.

[0003] The roller shutter box includes a passage which is adapted to the path of the roller shutter curtain.

[0004] However, roller shutter boxes may not offer optimal insulation, particularly in terms of thermal and acoustic insulation.

[0005] Indeed, there is a space between the roller shutter curtain and the longitudinal edges of the passage, through which noise, air (or even insects) can circulate.

[0006] To close this space, at least one of the longitudinal edges is conventionally equipped with an acoustic and / or thermal insulation device.

[0007] These insulating elements are generally in the form of brush seals, which are not entirely satisfactory:

[0008] - they may not create optimal insulation,

[0009] - they can deteriorate over time, resulting in a decrease in insulation,

[0010] - they can be difficult to clean.

[0011] There is therefore a need for isolation devices that would be adapted to overcome these problems. Presentation of the invention

[0012] In order to remedy the aforementioned drawbacks of the prior art, the present invention proposes a roller shutter box comprising a passage for a roller shutter curtain.

[0013] The passage is delimited by two longitudinal borders, at least one of which is equipped with an acoustic and / or thermal insulation device.

[0014] And according to the invention, said insulation element consists of a profiled seal made of an elastic material, and

[0015] which profiled joint comprises a front longitudinal strip which has an outer surface having a convex curved section, intended to extend in projection into said passage and intended to come into contact with said roller shutter curtain.

[0016] This solution according to the invention makes it possible to improve acoustic and thermal performance, whether the apron is in the raised position or in the lowered position.

[0017] The structure of the profiled joint, convex curve and elastic, allows to maintain contact with the apron without introducing a hard point, in the friction area, especially between two blades.

[0018] This profiled seal provides better sealing than a brush seal, without degradation over time.

[0019] Other non-limiting and advantageous features of the product according to the invention, taken individually or in all technically possible combinations, are as follows:

[0020] - the front longitudinal strip of the profiled joint is tubular; preferably, the strip The longitudinal front of the profiled, tubular joint is defined by a peripheral wall with a thickness ranging from 0.5 to 3 mm;

[0021] - the outer surface of the front longitudinal strip of the profiled joint has a convex curved section comprising a front portion in the form of an arc of a circle, preferably with a radius ranging from 1.5 to 5 mm; preferably, the outer surface of the front longitudinal strip of the profiled joint has a convex curved section which includes at least a front portion in the form of a semicircle, projecting into the passage; preferably again, the outer surface of the front longitudinal strip of the profiled joint includes a front portion in the form of a semicircle, projecting into the passage, which is continued by a lower portion rising in the form of an arc of a circle;

[0022] - the profiled seal comprises a rear longitudinal strip in the shape of a lip, intended to fill the space between the longitudinal edge and a masonry structure receiving said roller shutter box;

[0023] - the profiled joint comprises a longitudinal assembly strip which cooperates by interlocking by elastic deformation with a complementary strip of a longitudinal border of said passage;

[0024] - the profiled seal is attached directly to a wall of the roller shutter box, by for example a front wall or an underside, or by means of an added fixing profile, adjustable in relation to said wall of the roller shutter box;

[0025] - the front longitudinal strip of said profiled joint is notched to increase the air passage, particularly in the presence of a ventilation grille;

[0026] - the two longitudinal edges of the passage are equipped with said profiled joint, or a first longitudinal edge of the passage is equipped with said profiled joint, preferably the longitudinal edge of the passage located opposite the outer face of the roller shutter curtain, and a second longitudinal edge of the passage is equipped with an insulation element in the form of a brush;

[0027] The present invention also relates to a joinery assembly comprising:

[0028] - a glazed joinery,

[0029] - a roller shutter box, according to the invention.

[0030] Of course, the various features, variants, and embodiments of the invention can be combined with one another in various ways, provided they are not incompatible or mutually exclusive. Detailed description of the invention

[0031] In addition, various other features of the invention become apparent from the attached description made with reference to the drawings which illustrate non-limiting embodiments of the invention and where:

[0032] [Fig-1] is a general and cross-sectional view of the roller shutter box according to the invention, illustrating in particular the passage equipped with the profiled seal according to the invention;

[0033] [Fig.2] is a partial and enlarged view of [Fig. 1], showing in more detail the passage equipped with the profiled joint according to the invention;

[0034] [Fig.3] is a partial and enlarged view of [Fig.2], showing the joint in more detail profiled according to the invention.

[0035] It should be noted that, in these figures, the structural and / or functional elements common to the different variants may have the same references.

[0036] The roller shutter box 1 according to the invention, illustrated in figures 1 and 2, is intended to equip a joinery set E.

[0037] This joinery assembly E is intended to close off a building opening B which is provided in a masonry structure M.

[0038] In general, such a joinery assembly E comprises:

[0039] - a glazed V-shaped window, classic in itself, and

[0040] - the roller shutter box 1. Glazed joinery

[0041] Glazed joinery V includes, in particular, bay windows, advantageously hinged French doors, sliding French doors, or fixed joinery. Roller shutter box

[0042] The term “roller shutter box” advantageously encompasses all types of roller shutter boxes (new, renovation, tunnel), with internal or external winding.

[0043] The roller shutter box 1 advantageously comprises a casing 11 which is formed of a set of walls 12, advantageously longitudinal walls 12.

[0044] This roller shutter box 1 includes a passage 15 adapted to the movement of a roller shutter curtain 16 (in winding and unwinding).

[0045] As shown in more detail in [Fig.2], the passage 15 is delimited by two longitudinal borders 151.

[0046] For example, passage 15 is delimited by:

[0047] - a first longitudinal border 151a belonging to a first wall longitudinal 121, horizontal, forming a sub-face, and

[0048] - a second longitudinal border 151b belonging to a second wall longitudinal 122, vertical, forming a frontal wall.

[0049] The second longitudinal wall 122, frontal, is here intended to come opposite the masonry structure M, in this case on an inner face of the masonry structure M.

[0050] As described later in relation to [Fig.2], at least one of the longitudinal edges 151a, 151b is equipped with an insulation element 5,6 which is adapted to provide acoustic and / or thermal insulation at the level of this passage 15.

[0051] Moreover, in general, the roller shutter curtain 16 is formed, in a conventional manner, by an assembly of slats 161.

[0052] The roller shutter curtain 16 is carried by a winding shaft 162, advantageously a motorized winding shaft 162 ([Fig.l]). Insulation component

[0053] Generally, an insulation element 5, 6 is intended to fill the space between one of the longitudinal edges 151 and the slats 161 of the roller shutter curtain 16, to ensure thermal and / or acoustic insulation.

[0054] More specifically, an insulation element 5, 6 extends in the space between one of the longitudinal edges 151 and the opposite face of a blade 161.

[0055] This insulation element 5, 6 also allows the roller shutter curtain 16 to move freely without any blocking points, while maintaining the insulation regardless of the position of the roller shutter curtain 16.

[0056] As illustrated in particular in [Fig.2], the insulation element 5 according to the invention consists of a profiled seal 5 which is made of an elastic material.

[0057] By “elastic material”, we advantageously include any elastomeric material, for example silicone or EPDM rubber (acronym for ethylene-propylene-diene monomer).

[0058] According to the invention, as illustrated in particular by [Fig. 3], the profiled joint 5 comprises:

[0059] - a longitudinal band before 51, intended to project into the passage 15 and intended to come into contact with the roller shutter apron 16, and

[0060] - preferably, a rear longitudinal strip 52, intended to fill the space between the longitudinal border 151b equipped and the masonry structure M receiving the roller shutter box 1.

[0061] The longitudinal band before 51 thus extends advantageously within the space of the passage 15, defined by the longitudinal borders 151.

[0062] The longitudinal front band 51 of the profiled joint 5, intended to come into contact with the roller shutter curtain 16 (and in particular a face opposite the slats 161), has an outer surface 511 having a convex curved section.

[0063] In this case, the outer surface 511 advantageously comprises a front portion 51 in the shape of an arc of a circle, preferably with a radius ranging from 1.5 to 5 mm.

[0064] Preferably, the portion before 511a has a semi-circular section, projecting into passage 15.

[0065] Preferably, the outer surface 511 of the longitudinal front band 51 of the profiled joint 5 comprises a front portion 51 in a semicircle, projecting into the passage 15, which is continued by two portions:

[0066] - a lower portion 511b, ascending, here in an arc of a circle and in this case concave, And

[0067] - an upper portion 51 the, perpendicular to the axis of passage 15.

[0068] In other words, the outer surface 511 advantageously includes the front portion 51a in an arc of a circle, which is closed by the lower portion 511b and upper portion 511c converging, for example forming a V-shaped section.

[0069] According to an illustrated embodiment, the longitudinal front band 51 of the profiled joint 5 is advantageously tubular.

[0070] This longitudinal band 51 is then advantageously defined by a peripheral wall 512, of tubular shape, delimiting a hollow longitudinal volume 513.

[0071] Preferably, the peripheral wall 512 has a thickness ranging from 0.5 to 3 mm.

[0072] According to a preferred embodiment, the front longitudinal band 51 of the joint Profile 5 can be notched to increase airflow, especially in the presence of a ventilation grille.

[0073] The notches (not shown) are advantageously oriented perpendicular to the passage 15 (in an up / down or inside / outside direction relative to the roller shutter box 1).

[0074] Furthermore, the rear longitudinal band 52 is preferably in the shape of a lip.

[0075] This rear longitudinal strip 52 is intended to fill the space between the fitted longitudinal edge 151b and the masonry structure M.

[0076] This sealing is particularly interesting for insulation and for finishing (for example to hide a joint J added between the longitudinal edge 151b equipped and the masonry structure M).

[0077] This rear longitudinal strip 52 is advantageously bendable, when supported on the masonry structure M, to ensure optimal sealing.

[0078] Moreover, the profiled joint 5 advantageously comprises a longitudinal assembly strip 53 which cooperates by interlocking by elastic deformation with a complementary strip 7 of the longitudinal edge 151b of the passage 15.

[0079] Such an assembly facilitates the replacement of the profiled seal 5.

[0080] The longitudinal assembly strip 53 is here provided between the front longitudinal strip 51 and the rear longitudinal strip 52.

[0081] This longitudinal assembly strip 53 includes in particular a rib 531 which is intended to fit into a groove 71 complementary to the complementary strip 7.

[0082] In this case, the profiled joint 5 is advantageously brought in by means of a fixing profile 8, adjustable in relation to the longitudinal wall 122 equipped with the roller shutter box 1 and in relation to the longitudinal edge 151b of the passage 15.

[0083] This fixing profile 8 here carries the complementary strip 7 which is intended to receive the longitudinal assembly strip 53 of the profile joint 5.

[0084] The fixing profile 8 in this case has an angle bracket shape, with two flaps:

[0085] - a first part 81 bearing the complementary strip 7, and

[0086] - a second flap 82, secured to the longitudinal wall 122 of the flap box rolling 1 and / or the masonry structure M.

[0087] In this case, the second flap 82 is housed between the longitudinal wall 122 of the roller shutter box 1 and the masonry structure M.

[0088] The adjustment of the fixing profile 8, here in height, is allowed by this second part 82.

[0089] Alternatively, not shown, the profiled joint 5 is attached directly to a longitudinal wall 12 of the roller shutter box 1, for example the front wall 122 or the underside 121.

[0090] In this case, the additional strip 7 is directly provided on this longitudinal wall 12 of the roller shutter box 1.

[0091] Generally, a first longitudinal edge 151b of the passage 15 is equipped with the profiled seal 5 according to the invention, preferably the longitudinal edge 151b of the passage 15 located opposite the outer face of the roller shutter curtain 16.

[0092] A second longitudinal border 151a of the passage 15 can be equipped with an insulation element 6 in the form of a brush.

[0093] Alternatively, not shown, the two longitudinal edges 151 of the passage 15 can be equipped with the profiled joint 5 according to the invention. Implementation

[0094] In practice, at least one profiled seal 5 is attached to the roller shutter box 1.

[0095] In this case, the positioning of the profiled joint 5 is made possible by the assembly via the fixing profile 8.

[0096] In operation, the roller shutter curtain 16 is intended to travel within the passage 15.

[0097] During this path, the structure of the profiled joint 5, convex curve and elastic, allows to maintain contact with the roller shutter curtain 16.

[0098] The path of the roller shutter apron 16 is then obtained without generating a hard point, in the friction zone, especially between two slats 161.

[0099] Of course, various other modifications can be made to the invention within the scope of the annexed claims.
