Description

Title of the invention: Roller shutter box whose passage includes at least one insulating member 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 conventionally comprises a roller shutter box in which at least one apron is attached which is formed from an assembly of slats.

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

[0004] However, roller shutter boxes may not provide optimal insulation, particularly in terms of heat and sound.

[0005] In fact, there is a space between the roller shutter apron and the longitudinal edges of the passage, through which noise, air (and 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 member.

[0007] These insulating members 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, with the corollary of a drop in insulation,

[0010] - they can be difficult to clean.

[0011] There is therefore a need for isolation devices which would be suitable for overcoming these problems. Presentation of the invention

[0012] In order to overcome the aforementioned drawbacks of the state of the art, the present invention proposes a roller shutter box comprising a passage for a roller shutter apron.

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

[0014] And according to the invention, said insulating member consists of a profiled seal which is made of an elastic material, and

[0015] which profiled seal comprises a front longitudinal strip which comprises an outer surface having a convex curved section, intended to extend projecting into said passage and intended to come into contact with said roller shutter apron.

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

[0017] The structure of the profiled joint, convex and elastic curve, makes it possible to maintain contact with the apron without creating a hard point in the friction zone, 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 characteristics of the product according to the invention, taken individually or in all technically possible combinations, are the following:

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

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

[0022] - the profiled seal has a rear longitudinal strip in the form 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 em boxing by elastic deformation with a complementary band of a longitudinal edge of said passage;

[0024] - the profiled seal is attached directly to a wall of the roller shutter box, by example a front wall or a soffit, 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 seal, or a first longitudinal edge of the passage is equipped with said profiled seal, preferably the longitudinal edge of the passage located opposite the outer face of the roller shutter apron, and a second longitudinal edge of the passage is equipped with an insulating member in the form of a brush;

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

[0028] - glazed joinery,

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

[0030] Of course, the various features, variants and embodiments of the invention may be combined with each other in various combinations to the extent that they are not incompatible or mutually exclusive. Detailed description of the invention

[0031] Furthermore, various other characteristics of the invention emerge from the appended description given with reference to the drawings which illustrate non-limiting forms of embodiment of the invention and where:

[0032] [Fig-1] is a general and 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 seal according to the invention;

[0034] [Fig.3] is a partial and enlarged view of [Fig.2], showing in more detail the joint profile 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 assembly E.

[0037] This set of joinery E is intended to close a building bay B which is provided in a masonry structure M.

[0038] Generally speaking, such a joinery set E comprises:

[0039] - a V-shaped glass joinery, classic in itself, and

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

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

[0042] By "roller shutter box", we advantageously include all types of roller shutter box (new, renovation, tunnel), with internal or external rolling.

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

[0044] This roller shutter box 1 comprises a passage 15 adapted for the circulation of a roller shutter apron 16 (in rolling and unrolling).

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

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

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

[0048] - a second longitudinal edge 151b belonging to a second longitudinal wall tudinal 122, vertical, forming a front wall.

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

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

[0051] Furthermore, generally speaking, the roller shutter apron 16 is formed, in a conventional manner per se, by an assembly of slats 161.

[0052] The roller shutter apron 16 is carried by a winding shaft 162, advantageously a motorized winding shaft 162 ([Fig.l]). Isolation organ

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

[0054] More precisely, an insulating member 5, 6 extends in the space between one of the longitudinal edges 151 and the facing face of a blade 161.

[0055] This insulation member 5, 6 also allows the roller shutter apron 16 to move without any blocking point, while maintaining the insulation regardless of the position of the roller shutter apron 16.

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

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

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

[0059] - a front longitudinal strip 51, intended to extend projecting 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 equipped longitudinal edge 151b and the masonry structure M receiving the roller shutter box 1.

[0061] The front longitudinal strip 51 thus advantageously extends within the space occupied by the passage 15, defined by the longitudinal edges 151.

[0062] The front longitudinal strip 51 of the profiled seal 5, intended to come into contact with the roller shutter apron 16 (and in particular a face opposite the slats 161), comprises an external surface 511 having a convex curved section.

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

[0064] More preferably, the front portion 511a has a semi-circular section, projecting into the passage 15.

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

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

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

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

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

[0070] This longitudinal strip 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] Still according to a preferred embodiment, the front longitudinal strip 51 of the seal profile 5 can be notched to increase the air passage, particularly 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 inward / outward direction relative to the roller shutter box 1).

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

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

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

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

[0078] Furthermore, the profiled joint 5 advantageously comprises a longitudinal assembly strip 53 which cooperates by fitting together 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 arranged between the front longitudinal strip 51 and the rear longitudinal strip 52.

[0081] This longitudinal assembly strip 53 comprises in particular a rib 531 which is intended to be housed in a complementary groove 71 of the complementary strip 7.

[0082] In this case, the profiled seal 5 is advantageously attached by means of an attached fixing profile 8, adjustable relative to the longitudinal wall 122 equipped with the roller shutter box 1 and relative 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 profiled joint 5.

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

[0085] - a first flap 81 carrying 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 shutter 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 authorized by this second flap 82.

[0089] Alternatively, not shown, the profiled seal 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 apron 16.

[0092] A second longitudinal edge 151a of the passage 15 can be equipped with an insulating member 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 seal 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 seal 5 is made possible by the assembly via the fixing profile 8.

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

[0097] During this path, the structure of the profiled seal 5, convex and elastic curve, makes it possible to maintain contact with the roller shutter apron 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 may be made to the invention within the scope of the appended claims.
