Description

La présente invention concerne les volets roulants tels que ceux utilisés dans les bâtiments pour obturer des ouvertures telles que fenêtres ou portes.The present invention relates to shutters such as those used in buildings to seal openings such as windows or doors.

Un volet roulant comprend habituellement :

  • un tablier, formé de lames longitudinales articulées latéralement les unes aux autres selon leurs bords longitudinaux, apte à être déplacé sensiblement parallèlement à l'ouverture, et comportant une lame longitudinale d'extrémité formant généralement le bord inférieur libre du tablier,
  • un caisson de protection, apte à contenir le tablier, et comprenant une fente longitudinale de passage conformée pour laisser passer successivement lesdites lames longitudinales au cours du déplacement du tablier, le caisson de protection formant généralement le bord supérieur de l'ouverture,
  • un arbre d'enroulement, logé dans le caisson de protection, et autour duquel le tablier peut être enroulé,
  • des moyens d'entraînement pour entraîner en rotation l'arbre d'enroulement, de façon à manoeuvrer le tablier entre une position enroulée dans laquelle il est enroulé autour de l'arbre d'enroulement et dans laquelle la lame d'extrémité du tablier est au voisinage de la fente longitudinale de passage, le long du bord supérieur de l'ouverture, et une position déployée dans laquelle le tablier obture l'ouverture et dans laquelle la lame d'extrémité du tablier est à l'opposé du caisson de protection dans l'ouverture, le long du bord inférieur de l'ouverture.
A roller shutter usually includes:
  • an apron, formed of longitudinal blades articulated laterally to each other along their longitudinal edges, able to be displaced substantially parallel to the opening, and having a longitudinal end plate generally forming the free lower edge of the deck,
  • a protective box, adapted to contain the deck, and comprising a longitudinal passage slot shaped to pass successively said longitudinal blades during the movement of the deck, the protective box generally forming the upper edge of the opening,
  • a winding shaft, housed in the protective box, and around which the apron can be wound,
  • driving means for rotating the winding shaft, so as to operate the deck between a wound position in which it is wound around the winding shaft and in which the end blade of the deck is in the vicinity of the longitudinal passage slot, along the upper edge of the opening, and an extended position in which the apron closes the opening and in which the end plate of the deck is opposite the protective box in the opening, along the lower edge of the opening.

Voir, par exemple, les volets roulants décrits dans les documents DE 40 17 248 A1 et DE 203 01 691 U1 .See, for example, the shutters described in the documents DE 40 17 248 A1 and DE 203 01 691 U1 .

De façon habituelle, les lames longitudinales d'un tablier de volet roulant sont en polychlorure de vinyle.In the usual way, the longitudinal blades of a roll shutter apron are made of polyvinyl chloride.

Dans les volets roulants connus, en position enroulée, la lame d'extrémité du tablier est au voisinage de la fente longitudinale de passage. Cette lame d'extrémité n'obture pas la fente longitudinale de passage, mais laisse un passage de ventilation entre l'extérieur et l'intérieur du bâtiment. Cette ventilation est utile pour assainir le bâtiment, et on utilise généralement le caisson de protection lui-même comme passage de ventilation.In rolling shutters known, in wound position, the end blade of the deck is in the vicinity of the longitudinal slot passage. This end blade does not close the longitudinal slot of passage, but leaves a ventilation passage between the outside and the inside of the building. This ventilation is useful for sanitizing the building, and the protective box itself is generally used as a ventilation passage.

Toutefois, ce passage de ventilation est aussi une entrée par laquelle les insectes pénètrent fréquemment dans le caisson de protection. Une fois à l'intérieur, les insectes sont pris au piège et peuvent difficilement ressortir. Etant à l'abri, ils font leur nid, comme les abeilles par exemple. Il faut alors ouvrir le caisson de protection pour le débarrasser de ses "habitants".However, this passage of ventilation is also an entry through which insects frequently enter the protective box. Once inside, the insects are trapped and can hardly stand out. Being sheltered, they make their nest, like bees for example. It is then necessary to open the box of protection to rid it of its "inhabitants".

De plus, les insectes à l'intérieur du caisson de protection produisent des ondes sonores audibles et rapidement nuisibles. Ces ondes sonores sont également comme prises au piège dans le caisson de protection et résonnent.In addition, the insects inside the protective box produce audible and rapidly harmful sound waves. These sound waves are also trapped in the protective box and resonate.

Le caisson de protection devient alors une caisse de résonance amplifiant naturellement les ondes sonores.The protective box then becomes a sound box naturally amplifying the sound waves.

De façon plus nuisible, le passage de ventilation autorise la transmission de bruits entre l'intérieur et l'extérieur du bâtiment et réciproquement.More deleteriously, the ventilation passage allows the transmission of noise between the inside and the outside of the building and vice versa.

Afin de réduire cette nuisance, on a pensé recouvrir les parois intérieures du caisson de protection avec des matériaux isolants phoniquement.In order to reduce this nuisance, it has been thought to cover the inner walls of the protective box with sound insulating materials.

Cette solution se révèle cependant toujours insuffisante.However, this solution is still insufficient.

Au regard du document DE202005002160U1 , le problème proposé par la présente invention serait de concevoir un volet roulant pour obturation d'une ouverture, facile à fabriquer, robuste, et réduisant efficacement la transmission de bruits phoniques.With regard to the document DE202005002160U1 , the problem proposed by the present invention would be to design a shutter for closing an opening, easy to manufacture, robust, and effectively reducing the transmission of acoustic noise.

Pour atteindre ces buts ainsi que d'autres, l'invention propose un volet roulant pour obturation d'une ouverture, comprenant :

  • un tablier, formé de lames longitudinales articulées latéralement les unes aux autres selon leurs bords longitudinaux, apte à être déplacé sensiblement parallèlement à l'ouverture, et comportant une lame longitudinale d'extrémité formant généralement le bord inférieur libre du tablier,
  • un caisson de protection, apte à contenir le tablier, et comprenant une fente longitudinale de passage conformée pour laisser passer successivement lesdites lames longitudinales au cours du déplacement du tablier, le caisson formant généralement le bord supérieur de l'ouverture,
  • un arbre d'enroulement, logé dans le caisson de protection, et autour duquel le tablier peut être enroulé,
  • des moyens d'entraînement pour entraîner en rotation l'arbre d'enroulement, de façon à manoeuvrer le tablier entre une position enroulée dans laquelle il est enroulé autour de l'arbre d'enroulement et dans laquelle la lame d'extrémité du tablier est au voisinage de la fente longitudinale de passage, le long du bord supérieur de l'ouverture, et une position déployée dans laquelle le tablier obture l'ouverture et dans laquelle la lame d'extrémité du tablier est à l'opposé du caisson de protection dans l'ouverture, le long du bord inférieur de l'ouverture,
    et dans lequel :
  • la lame d'extrémité et la fente longitudinale de passage du caisson de protection sont conformées de façon que la lame d'extrémité obture la fente longitudinale de passage du caisson de protection lorsque le tablier est en position enroulée,
  • la lame d'extrémité est monobloc, et
  • la lame d'extrémité comprend une portion d'obturation dont l'épaisseur est supérieure à la largeur de la fente longitudinale de passage et dont deux faces opposées viennent buter contre les lèvres respectives de la fente longitudinale de passage en position enroulée du tablier.
To achieve these and other objects, the invention provides a shutter for closing an opening, comprising:
  • an apron, formed of longitudinal blades articulated laterally to each other along their longitudinal edges, able to be displaced substantially parallel to the opening, and having a longitudinal end plate generally forming the free lower edge of the deck,
  • a protective box, adapted to contain the deck, and comprising a longitudinal slot passage shaped to pass successively said longitudinal blades during the movement of the deck, the box generally forming the upper edge of the opening,
  • a winding shaft, housed in the protective box, and around which the apron can be wound,
  • driving means for rotating the winding shaft, so as to operate the deck between a wound position in which it is wound around the winding shaft and in which the end blade of the deck is in the vicinity of the longitudinal passage slot, along the upper edge of the opening, and an extended position in which the apron closes the opening and in which the end plate of the deck is opposite the protective box in the opening, along the lower edge of the opening,
    and wherein:
  • the end blade and the longitudinal passage slot of the protective box are shaped so that the end plate closes the longitudinal passage slot of the protective box when the apron is in the wound position,
  • the end blade is monoblock, and
  • the end plate comprises a closing portion whose thickness is greater than the width of the longitudinal slot passage and two opposite faces abut against the respective lips of the longitudinal slot passage in rolled position of the deck.

Le volet roulant ainsi conçu permet d'éviter que les bruits ne soient transmis de l'intérieur vers l'extérieur du bâtiment et réciproquement.The shutter thus designed prevents noise from being transmitted from the inside to the outside of the building and vice versa.

De plus, une telle conception simple, offre l'avantage qu'un volet roulant déjà installé pour obturer une ouverture, peut être aisément modifié par le simple remplacement de la lame d'extrémité du volet existant par une lame d'extrémité apte à assurer l'obturation de la fente longitudinale de passage. Cette modification se fait donc à moindre coût, il n'y a en effet pas d'obligation de changer la totalité du volet roulant.In addition, such a simple design, has the advantage that a roller shutter already installed to close an opening, can be easily modified by simply replacing the end blade of the existing flap with an end blade capable of ensuring the closing of the longitudinal slot of passage. This modification is therefore done at lower cost, there is indeed no obligation to change the entire roller shutter.

Le profilé monobloc de la lame d'extrémité est facile à fabriquer, et cette configuration limite les problèmes de détachement, de déformations ou autres dégradations des facettes transversales d'obturation. Par exemple, cela réduit le risque d'une dégradation provoquée par un utilisateur qui forcerait la poursuite de l'enroulage du volet roulant au-delà de la position enroulée.The one-piece profile of the end blade is easy to manufacture, and this configuration limits the problems of detachment, deformation or other degradation of the transverse shutter facets. For example, this reduces the risk of user-induced degradation that would force the rolling shutter to continue rolling past the wound position.

Grâce à une telle portion d'obturation, l'obturation recherchée de la fente longitudinale de passage s'effectue naturellement.Thanks to such a sealing portion, the desired obturation of the longitudinal passage slot occurs naturally.

On peut par exemple donner à la lame d'extrémité une forme de coin inversé, la lame d'extrémité pénétrant partiellement dans le caisson de protection par la fente longitudinale de passage jusqu'à venir en butée contre les lèvres respectives de la fente longitudinale de passage en position enroulée du tablier.For example, the end plate may have an inverted wedge shape, the end blade penetrating partially into the protective casing through the longitudinal passage slot until it abuts against the respective lips of the longitudinal slot of the end slot. passage in rolled position of the apron.

On peut également donner à la lame d'extrémité toute autre forme qui permette cette obturation mécanique automatique.We can also give the end blade any other shape that allows this automatic mechanical shutter.

De préférence, on peut prévoir que la portion d'obturation comprend deux facettes transversales d'obturation, disposées respectivement sur l'une et l'autre des faces opposées de la lame d'extrémité, et venant en appui contre les lèvres de la fente longitudinale de passage en position enroulée du tablier.Preferably, it can be provided that the closure portion comprises two transverse shutter facets, respectively disposed on one and the other of the opposite faces of the end plate, and bearing against the lips of the slot longitudinal passage of rolled position of the apron.

Ces facettes transversales d'obturation facilitent la réalisation d'une obturation étanche qui assure une bonne isolation phonique.These transverse shutter facets facilitate the realization of a tight seal which provides good sound insulation.

On peut avantageusement prévoir que les facettes transversales d'obturation sont sensiblement coplanaires et perpendiculaires au plan moyen du tablier.It can advantageously be provided that the transverse shutter facets are substantially coplanar and perpendicular to the average plane of the deck.

Ainsi, l'obturation de la fente longitudinale de passage se fera de façon naturelle.Thus, the closing of the longitudinal slot passage will be done naturally.

On peut aussi donner aux facettes transversales d'obturation des dimensions différentes, pour remplir d'autres fonctions.The transverse facets of closure can also be given different dimensions to fulfill other functions.

Ainsi, une même lame d'extrémité ayant au moins une facette transversale surdimensionnée peut être utilisée pour obturer la fente longitudinale de passage de plusieurs types de caisson de protection ayant des dimensions différentes.Thus, the same end blade having at least one oversized transverse facet can be used to close the longitudinal slot passage of several types of protective box having different dimensions.

De façon avantageuse, on peut prévoir un joint d'étanchéité interposé entre chacune des faces opposées de la lame d'extrémité et les lèvres correspondantes de la fente longitudinale de passage.Advantageously, it is possible to provide a seal interposed between each of the opposite faces of the end plate and the corresponding lips of the longitudinal passage slot.

Le joint d'étanchéité assure l'étanchéité de l'obturation de la fente longitudinale de passage.The seal seals the sealing of the longitudinal slot passage.

Ainsi, on améliore encore l'étanchéité de l'obturation, et l'isolation phonique.Thus, it improves further the sealing of the shutter, and the sound insulation.

Selon un premier mode de réalisation, on peut prévoir que les joints d'étanchéité sont portés par la lame d'extrémité.According to a first embodiment, it can be provided that the seals are carried by the end plate.

Selon un second mode de réalisation, on peut prévoir que les joints d'étanchéité sont sur les lèvres de la fente longitudinale de passage.According to a second embodiment, it can be provided that the seals are on the lips of the longitudinal slot passage.

Ces deux modes de réalisation permettent d'assurer une obturation efficace de la fente longitudinale de passage.These two embodiments make it possible to effectively seal the longitudinal passage slot.

On peut prévoir que ces joints sont élastiques et peuvent s'écraser en partie pour que l'étanchéité soit meilleure.It can be expected that these seals are resilient and can be partially crushed so that the seal is better.

Afin d'assurer encore la ventilation utile à l'assainissement d'un bâtiment, on peut avantageusement prévoir un passage de ventilation en dérivation du caisson de protection.To further ensure the ventilation useful for the sanitation of a building, it is advantageous to provide a ventilation passage bypassing the protective box.

Ainsi, la ventilation d'un bâtiment est assurée en permanence, même lorsque la fente longitudinale de passage du caisson de protection est obturée par la lame d'extrémité.Thus, the ventilation of a building is ensured permanently, even when the longitudinal slot passage of the protective box is closed by the end blade.

De façon avantageuse, on peut prévoir un passage de ventilation comprenant une structure en chicanes qui s'oppose à une transmission phonique.Advantageously, it is possible to provide a ventilation passage comprising a baffled structure which opposes a sound transmission.

Le bruit ne peut ainsi pas se propager dans le passage de ventilation et est arrêté par les chicanes successives.The noise can not propagate in the ventilation passage and is stopped by successive baffles.

De façon avantageuse, on peut prévoir que la lame d'extrémité soit en aluminium, afin de lui conférer une résistance mécanique accrue lui permettant de supporter des sollicitations mécaniques importantes en fin d'enroulage du tablier, alors que les autres lames du tablier, moins sollicitées peuvent être en matière plastique.Advantageously, it can be provided that the end plate is made of aluminum, in order to confer on it an increased mechanical resistance enabling it to withstand heavy mechanical stresses at the end of the winding of the deck, while the other deck blades, less stressed can be plastic.

Les figures 1 à 6 illustrent en coupe transversale un caisson de protection 2 avec un volet roulant 1 en position enroulée dans des modes de réalisation de l'art antérieur et dans des modes de réalisation selon l'invention.The Figures 1 to 6 illustrate in cross-section a protective box 2 with a shutter 1 in the wound position in embodiments of the prior art and in embodiments according to the invention.

Certains éléments structurels sont communs à l'art antérieur et à la présente invention. Ils vont être décrits plus en détails ci-dessous avec la description des figures 1 et 2.Certain structural elements are common to the prior art and the present invention. They will be described in more detail below with the description of the figures 1 and 2 .

Les figures 1 et 2 illustrent deux configurations de l'art antérieur, dans lesquelles un volet roulant comprend un tablier 1, et est formé de lames longitudinales L. Les lames longitudinales L sont articulées latéralement les unes aux autres selon leurs bords longitudinaux. En outre, le tablier 1 comprend une lame longitudinale d'extrémité L'.The figures 1 and 2 illustrate two configurations of the prior art, in which a roller shutter comprises an apron 1, and is formed of longitudinal blades L. The longitudinal blades L are articulated laterally to each other along their longitudinal edges. In addition, the apron 1 comprises a longitudinal end blade L '.

La lame longitudinale d'extrémité L'est de section sensiblement oblongue et présente deux faces opposées F1 et F2. Elle présente une épaisseur E d'environ 10 mm.The longitudinal end plate L'is of substantially oblong section and has two opposite faces F1 and F2. It has a thickness E of about 10 mm.

Le tablier 1 est destiné à être enroulé autour d'un arbre d'enroulement 4, localisé dans un caisson de protection 2.The apron 1 is intended to be wrapped around a winding shaft 4, located in a protective box 2.

Le caisson de protection 2 est une structure généralement parallélépipédique limitée notamment par une paroi supérieure 2a, une paroi inférieure 2b, une paroi intérieure 2c et une paroi extérieure 2d. Un matériau alvéolaire 2e recouvre intérieurement notamment la paroi intérieure 2c, pour assurer une isolation essentiellement thermique.The protective casing 2 is a generally parallelepipedal structure limited in particular by an upper wall 2a, a bottom wall 2b, an inner wall 2c and an outer wall 2d. In particular, a cellular material 2e internally covers the inner wall 2c, to provide essentially thermal insulation.

Le caisson de protection 2 comprend, dans sa paroi inférieure 2b, une fente longitudinale de passage 3 inférieure, délimitée par deux lèvres 3a et 3b pour laisser passer successivement lesdites lames longitudinales L au cours de leur déplacement illustré par la double flèche D. Cette fente longitudinale de passage 3 présente une largeur L1 d'environ 14 mm.The protective casing 2 comprises, in its lower wall 2b, a longitudinal slot 3 of passage 3, delimited by two lips 3a and 3b to pass successively said longitudinal blades L during their movement illustrated by the double arrow D. This slot longitudinal passage 3 has a width L1 of about 14 mm.

Le caisson de protection 2 est placé le long du bord supérieur d'une ouverture 100 d'un bâtiment, dans une feuillure 101 du mur supérieur 102 qui, avec le mur inférieur 103, délimite l'ouverture 100. Le volet roulant sert à obturer sélectivement l'ouverture 100.The protective box 2 is placed along the upper edge of an opening 100 of a building, in a rebate 101 of the upper wall 102 which, with the lower wall 103, defines the opening 100. The shutter is used to seal selectively the opening 100.

Lors de l'utilisation du volet roulant, l'utilisateur commande, manuellement ou électriquement, des moyens d'entraînement tels qu'un treuil à manivelle, un treuil à sangle, un moteur électrique, pour entraîner en rotation l'arbre d'enroulement 4 de façon à enrouler le tablier 1 autour de l'arbre d'enroulement 4, localisé dans le caisson de protection 2, ou à le dérouler pour ajuster l'obturation de l'ouverture 100.When using the rolling shutter, the user controls, manually or electrically, drive means such as a crank winch, a belt winch, an electric motor, for rotating the winding shaft. 4 so as to wind the apron 1 around the winding shaft 4, located in the protective casing 2, or to unroll it to adjust the closure of the opening 100.

En position d'obturation, le tablier 1 obture entièrement l'ouverture 100, et est situé selon un plan moyen A-A.In the closed position, the apron 1 completely closes the opening 100, and is located on a medium plane A-A.

En position enroulée, la lame d'extrémité L' du tablier 1 est localisée au voisinage de la fente longitudinale de passage 3, de telle sorte que la face F1 de la lame d'extrémité L' est située au regard de la lèvre 3a et la face F2 de la lame d'extrémité L' est située au regard de la lèvre 3b.In wound position, the end blade L 'of the apron 1 is located near the longitudinal passage slot 3, so that the face F1 of the end plate L' is located opposite the lip 3a and the face F2 of the end plate L 'is located opposite the lip 3b.

L'épaisseur E de la lame d'extrémité L' étant plus petite que la largeur de la fente longitudinale de passage 3, toutes sortes d'ondes et d'insectes peuvent s'introduire dans le caisson de protection 2 en passant entre la lame d'extrémité L' et les lèvres 3a et 3b.The thickness E of the end blade L 'being smaller than the width of the longitudinal passage slot 3, all kinds of waves and insects can be introduced into the protective box 2 by passing between the blade L 'end and the lips 3a and 3b.

Les ondes sonores sont ainsi transmises de l'intérieur Y du bâtiment vers l'extérieur X du bâtiment et réciproquement.The sound waves are thus transmitted from the interior Y of the building to the outside X of the building and vice versa.

La figure 2 illustre une seconde configuration de l'art antérieur, dans laquelle on ajoute au dispositif de la figure 1 un recouvrement interne 9 du caisson de protection 2. Ce recouvrement interne 9 a pour objet d'amortir les ondes sonores qui pénètrent dans le caisson de protection, afin d'éviter leur transmission entre l'intérieur et l'extérieur du bâtiment.The figure 2 illustrates a second configuration of the prior art, in which is added to the device of the figure 1 an internal covering 9 of the protective box 2. The purpose of this internal covering 9 is to dampen the sound waves that penetrate into the protective box, in order to prevent their transmission between the inside and the outside of the building.

Ce recouvrement interne 9 recouvre une portion de la paroi intérieure 2c du caisson de protection 2 qui est orientée vers l'intérieur du bâtiment, une portion de la paroi supérieure 2a et une portion de la paroi inférieure 2b du caisson de protection 2. Ce recouvrement interne 9 n'assure toutefois pas un amortissement suffisant des ondes sonores.This internal covering 9 covers a portion of the inner wall 2c of the protective box 2 which is oriented towards the interior of the building, a portion of the upper wall 2a and a portion of the lower wall 2b of the protective box 2. This overlap internal 9 does not ensure sufficient damping of sound waves.

Les figures 3 à 6 illustrent des modes de réalisation selon la présente invention. Les éléments structurels repérés par les mêmes références numériques que ceux des figures 1 et 2 sont communs à l'invention et à l'état de la technique, et ils ne sont donc pas décrits à nouveau.The Figures 3 to 6 illustrate embodiments according to the present invention. Structural elements identified by the same numerical references as those of figures 1 and 2 are common to the invention and the state of the art, and therefore are not described again.

Les figures 3 et 4 illustrent un volet roulant selon une première et une seconde configurations d'un premier mode de réalisation de la présente invention.The figures 3 and 4 illustrate a rolling shutter according to first and second configurations of a first embodiment of the present invention.

Sur les figures 3 et 4, la lame d'extrémité L' comprend deux ailes latérales 5a et 5b opposées dont les faces supérieures définissent deux facettes transversales d'obturation 5c et 5d, disposées respectivement sur l'une et l'autre des faces principales opposées F1 et F2 de la lame d'extrémité L'. Les deux facettes transversales d'obturation 5c et 5d sont sensiblement coplanaires et perpendiculaires au plan moyen A-A du tablier 1.On the figures 3 and 4 , the end plate L 'comprises two opposite lateral wings 5a and 5b, the upper faces of which define two transverse shutter facets 5c and 5d, respectively disposed on the opposite main faces F1 and F2 of the end blade L '. The two transverse shutter facets 5c and 5d are substantially coplanar and perpendicular to the average plane AA of the apron 1.

Ces deux facettes transversales 5c et 5d constituent une portion d'obturation d'épaisseur E qui est supérieure à la largeur L1 de la fente longitudinale de passage 3. Grâce à ces dimensions, les deux facettes transversales 5c et 5d constituent donc un arrêt mécanique simple de l'enroulage du tablier 1.These two transverse facets 5c and 5d constitute a closure portion of thickness E which is greater than the width L1 of the longitudinal passage slot 3. Thanks to these dimensions, the two transverse facets 5c and 5d therefore constitute a simple mechanical stop. winding the apron 1.

En position enroulée du tablier 1, les deux facettes transversales d'obturation 5c et 5d sont en appui contre les lèvres 3a et 3b de la fente longitudinale de passage 3.In the wound position of the apron 1, the two transverse shutter faces 5c and 5d bear against the lips 3a and 3b of the longitudinal passage slot 3.

Afin d'augmenter l'étanchéité du caisson de protection 2, un joint d'étanchéité 6 est interposé entre chacune des faces opposées F1 et F2 de la lame d'extrémité L' et les lèvres correspondantes 3a et 3b de la fente longitudinale de passage 3.In order to increase the sealing of the protective casing 2, a seal 6 is interposed between each of the opposite faces F1 and F2 of the end blade L 'and the corresponding lips 3a and 3b of the longitudinal passage slot. 3.

La présence des joints d'étanchéité 6 permet de gagner encore 5 dB d'affaiblissement des ondes acoustiques transmises, et ainsi de passer à une meilleure classe, selon la classification acoutherme du Centre Scientifique et Technique du Bâtiment.The presence of the seals 6 makes it possible to save another 5 dB of weakening of the acoustic waves transmitted, and thus to move to a better class, according to the classification acutherme of the Scientific and Technical Center of the Building.

Dans les modes de réalisation illustrés sur les figures 3 à 6, les joints d'étanchéité 6 sont des profilés en forme de demi-cylindre creux, en élastomère. Avec une telle conformation, les joints d'étanchéité 6 présentent une grande capacité d'écrasement élastique. Ceci leur permet, notamment, de s'adapter aux défauts de construction des bâtiments pour, malgré ceux-ci, assurer une bonne étanchéité.In the embodiments illustrated on the Figures 3 to 6 , the seals 6 are hollow half-cylinder shaped profiles of elastomer. With such a conformation, the seals 6 have a large capacity of elastic crushing. This allows them, in particular, to adapt to defects in the construction of buildings, despite these, ensure a good seal.

Ces joints d'étanchéité 6 peuvent avoir un diamètre sensiblement égal à la moitié de la longueur de la facette transversale d'obturation 5c ou 5d la plus petite, ou à la moitié de l'épaisseur de la lame d'extrémité L'.These seals 6 may have a diameter substantially equal to half the length of the transverse shutter facet 5c or 5d the smallest, or half the thickness of the end plate L '.

L'étanchéité acoustique procurée par de tels joints 6 en demi-cylindre creux est excellente, probablement grâce au fait qu'ils constituent une paroi double formant deux barrières successives que les ondes sonores doivent traverser.The acoustic seal provided by such joints 6 hollow half-cylinder is excellent, probably because they constitute a double wall forming two successive barriers that the sound waves must cross.

Dans le premier mode de réalisation illustré sur les figures 3 et 4, la lame d'extrémité L' porte un joint d'étanchéité 6 sur chacune des deux facettes transversales 5c et 5d.In the first embodiment illustrated on the figures 3 and 4 , the end blade L carries a seal 6 on each of the two transverse facets 5c and 5d.

Chaque joint d'étanchéité 6 est par exemple collé par sa face diamétrale plane sur l'une des facettes transversales 5c et 5d.Each seal 6 is for example glued by its flat diametrical face on one of the transverse facets 5c and 5d.

Dans la configuration représentée sur la figure 4, on retrouve le recouvrement interne 9 de la figure 2.In the configuration shown on the figure 4 , we find the internal recovery 9 of the figure 2 .

La figure 5 illustre un second mode de réalisation de l'invention, selon lequel un joint d'étanchéité 6 est prévu sur chacune des lèvres 3a et 3b de la fente longitudinale de passage 3, et orienté pour porter contre les facettes transversales 5c ou 5d correspondantes en position enroulée du tablier 1.The figure 5 illustrates a second embodiment of the invention, wherein a seal 6 is provided on each of the lips 3a and 3b of the longitudinal slot passage 3, and oriented to bear against the corresponding transverse facets 5c or 5d in position wrapped around the apron 1.

Dans ce mode de réalisation, chaque joint d'étanchéité 6 comporte une lame de fixation 6a engagée dans une rainure en contre-dépouille 30 de l'une des lèvres 3a et 3b de la fente longitudinale de passage 3.In this embodiment, each seal 6 comprises a fixing blade 6a engaged in an undercut groove 30 of one of the lips 3a and 3b of the longitudinal passage slot 3.

La figure 6 illustre le dispositif de la figure 4 auquel un passage de ventilation 7 a été ajouté en dérivation du caisson de protection 2.The figure 6 illustrates the device of the figure 4 to which a ventilation passage 7 has been added as a bypass of the protective casing 2.

Pour éviter que le passage de ventilation soit une sorte de conduit par lequel des ondes sonores pourraient être transmises, le passage de ventilation 7 comprend une structure en chicanes 8a, 8b, 8c pour s'opposer à une transmission phonique.To prevent the ventilation passage from being a kind of conduit through which sound waves could be transmitted, the ventilation passage 7 comprises a baffled structure 8a, 8b, 8c to oppose a sound transmission.

Des tests acoustiques ont été réalisés sur les volets roulants des figures 1 à 4. Au cours de ces tests, on a mesuré l'affaiblissement des ondes sonores transmises entre l'extérieur et l'intérieur du bâtiment. Les résultats sont regroupés dans le tableau : Art antérieur (figure 1) 41 dB Art antérieur (figure 2) 46 dB Invention (figure 3) 51 dB Invention (figure 4) 54 dB Acoustic tests were carried out on the rolling shutters of Figures 1 to 4 . During these tests, the attenuation of the sound waves transmitted between the outside and the inside of the building was measured. The results are grouped in the table: Prior art ( figure 1 ) 41 dB Prior art ( figure 2 ) 46 dB Invention ( figure 3 ) 51 dB Invention ( figure 4 ) 54 dB

On constate ainsi, en comparant les résultats des volets roulants des figures 1 et 3, que l'invention permet dans ce cas d'affaiblir sensiblement les ondes transmises, et permet de gagner 10 dB.Thus, by comparing the results of rolling shutters with figures 1 and 3 , that the invention allows in this case to substantially weaken the transmitted waves, and can earn 10 dB.

On constate aussi, en comparant les résultats des volets roulants des figures 2 et 4, que l'invention permet dans ce cas de gagner 8 dB.We can also see, by comparing the results of roller shutters figures 2 and 4 , that the invention allows in this case to gain 8 dB.

L'oreille humaine arrive à percevoir des différences d'environ 3 dB. Le bruit est donc réduit de façon significative grâce à l'invention.The human ear can perceive differences of about 3 dB. The noise is therefore significantly reduced thanks to the invention.

La présente invention n'est pas limitée aux modes de réalisation qui ont été explicitement décrits, mais elle en inclut les diverses variantes et généralisations contenues dans le domaine des revendications ci-après.The present invention is not limited to the embodiments which have been explicitly described, but it includes the various variants and generalizations thereof within the scope of the claims below.
