Description

La prĆ©sente invention a pour objet une lamelle rĆ©sistant au feu dont plusieurs sont destinĆ©es Ć  ĆŖtre associĆ©es les unes aux autres pour former une porte apte Ć  ĆŖtre dĆ©placĆ©e entre une position de fermeture et une position ouverte, et inversement, en suivant avantageusement un chemin de guidage au moins partiellement courbe et/ou au moyen d'un systĆØme permettant l'enroulement ou le dĆ©roulement de la porte ou cloison par rapport Ć  un support, ladite lamelle comprenant :

  • une enveloppe longitudinale en matiĆØre plastique dĆ©finissant une chambre, la dite enveloppe prĆ©sentant au moins une premiĆØre et une deuxiĆØme faces longitudinales destinĆ©es Ć  dĆ©finir les faces avant et arriĆØre de l'enveloppe, et des premiĆØre et deuxiĆØme faces latĆ©rales s'Ć©tendant respectivement entre une extrĆ©mitĆ© de la premiĆØre face longitudinale et une extrĆ©mitĆ© de la deuxiĆØme face longitudinale,
  • une matiĆØre intumescente remplissant au moins partiellement ladite chambre,
  • une gorge longitudinale s'Ć©tendant le long de la premiĆØre face latĆ©rale,
  • une protubĆ©rance longitudinale s'Ć©tendant le long de la deuxiĆØme face latĆ©rale, ladite gorge d'une premiĆØre face latĆ©rale de la lamelle considĆ©rĆ©e Ć©tant adaptĆ©e pour recevoir la protubĆ©rance longitudinale d'une deuxiĆØme face latĆ©rale d'une autre lamelle placĆ©e de maniĆØre adjacente Ć  la lamelle considĆ©rĆ©e, tandis que la protubĆ©rance de la deuxiĆØme face latĆ©rale de la lamelle considĆ©rĆ©e est adaptĆ©e pour s'engager dans la gorge d'une premiĆØre face latĆ©rale d'une autre lamelle placĆ©e de maniĆØre adjacente Ć  la lamelle considĆ©rĆ©e.
The present invention relates to a fire-resistant blade, several of which are intended to be associated with each other to form a door capable of being moved between a closed position and an open position, and vice versa, advantageously following a guide path at least partially curved and / or by means of a system allowing the winding or unwinding of the door or partition with respect to a support, said strip comprising:
  • a longitudinal plastic envelope defining a chamber, said envelope having at least first and second longitudinal faces intended to define the front and rear faces of the envelope, and first and second lateral faces respectively extending between one end the first longitudinal face and one end of the second longitudinal face,
  • an intumescent material at least partially filling said chamber,
  • a longitudinal groove extending along the first lateral face,
  • a longitudinal protuberance extending along the second lateral face, said groove of a first lateral face of the lamella considered being adapted to receive the longitudinal protuberance of a second lateral face of another lamella placed adjacent to the lamella considered, while the protrusion of the second side face of the lamella considered is adapted to engage in the groove of a first side face of another lamella placed adjacent to the lamella considered.

Une lamelle de ce type est connu par le document EP1591614 .A slide of this type is known from the document EP1591614 .

Bien que la porte prĆ©parĆ©e au moyen de lamelles selon ce document EP1591614 permet une protection anti feu, la porte prĆ©sente des passages prĆ©fĆ©rentiels pour les flammes entre les lamelles. Ainsi, lorsque la porte n'est pas abaissĆ©e correctement, des passages peuvent ĆŖtre formĆ©s entre deux lamelles adjacentes, en particulier dans le haut de la porte en position fermĆ©e.Although the door prepared by means of slats according to this document EP1591614 allows a fire protection, the door has preferential passages for the flames between the lamellae. So when the door is not lowered correctly, passages may be formed between two adjacent lamellae, particularly at the top of the door in the closed position.

Dans le document EP1591614 , les lamelles sont attachĆ©es les unes aux autres par des cĆ¢bles en acier, traversant les protubĆ©rances et les gorges des faces latĆ©rales des lamelles. Le placement de tels cĆ¢bles dans les diffĆ©rentes lamelles est une opĆ©ration compliquĆ©e. Lors d'un mouvement des lamelles le long d'un chemin courbe, les cĆ¢bles induisent une tension dans les lamelles et entre les lamelles, tensions pouvant causer certaines dĆ©gradations au niveau des protubĆ©rances ou gorges.In the document EP1591614 , the slats are attached to each other by steel cables, passing through the protuberances and grooves of the side faces of the slats. The placement of such cables in the different lamellae is a complicated operation. During a movement of the lamellae along a curved path, the cables induce a tension in the lamellae and between the lamellae, tensions that may cause certain degradations at the level of the protuberances or grooves.

La porte obtenue au moyen de lamelles selon ce document est toujours combustible, de sorte qu'en cas de feu prolongĆ©, une ou des ouvertures importantes peuvent ĆŖtre crĆ©Ć©es.The door obtained by means of lamellae according to this document is always combustible, so that in case of prolonged fire, one or more important openings can be created.

La porte obtenue au moyen de telles lamelles ne prƩsente qu'une rƩsistance limitƩe Ơ l'effraction, ainsi qu'une rƩsistance limitƩe aux chocs, ou souffles, etc.The door obtained by means of such slats has only a limited resistance to burglary, as well as limited resistance to shocks, or blows, etc.

Enfin, on a remarquĆ© que lors de feu trĆØs intense, la destruction d'une lamelle permettait le passage direct de la flamme, tandis que pour des portes de largeur, des mouvements entre lamelles Ć©taient possibles en cas de diffĆ©rence de tempĆ©ratures appliquĆ©es entre les parties verticales extrĆŖmes de la porte.Finally, it was noted that during very intense fire, the destruction of a lamella allowed the direct passage of the flame, while for wide doors, movements between lamellae were possible in case of temperature difference between the parts extreme verticals of the door.

On connaĆ®t par la figure 3 du document DE 199 07 801 une lamelle constituĆ©e d'un corps de base en mĆ©tal associĆ© Ć  un manteau en matiĆØre plastique dĆ©finissant de part et d'autre du corps de base en mĆ©tal profilĆ© mĆ©tallique, des chambres munies de renforts. Les chambres ne contiennent pas de matiĆØre intumescente. Les lamelles dĆ©crite Ć  la figure 3 de ce document prĆ©sentent chacune un crochet supĆ©rieur et un crochet infĆ©rieur, le crochet infĆ©rieur d'une lamelle Ć©tant destinĆ© Ć  prendre appui dans le crochet supĆ©rieur d'une lamelle adjacente lors de l'ouverture du volet. En position fermĆ©e du volet, le crochet supĆ©rieur d'une lamelle ne prend pas appui dans la gorge du crochet infĆ©rieur d'une lamelle adjacente. En cas d'incendie, la partie de la chambre extĆ©rieure adjacente du crochet infĆ©rieur de chaque lamelle va fondre et/ou se consumer, de sorte qu'en position fermĆ©e, des mouvements entre les profilĆ©s mĆ©talliques (par exemple bombage par rapport Ć  un axe vertical) se produiront et crĆ©eront des passages entre profilĆ©s mĆ©talliques de lamelles adjacentes pour le feu, la chaleur, les fumĆ©es, etc.
Les lamelles du document DE19907801 , mĆŖme remplies de matiĆØre intumescente, sont donc inaptes Ć  former une paroi rĆ©sistant au feu.
We know by figure 3 of the document DE 199 07 801 a lamella consisting of a metal base body associated with a plastic jacket defining on either side of the metal profiled metal base body, chambers provided with reinforcements. The rooms do not contain intumescent material. The slats described in figure 3 of this document each have an upper hook and a lower hook, the lower hook of a slat being intended to bear in the upper hook of an adjacent slat when opening the shutter. In the closed position of the shutter, the upper hook of a strip does not take not support in the groove of the lower hook of an adjacent lamella. In case of fire, the portion of the outer chamber adjacent to the lower hook of each lamella will melt and / or burn, so that in the closed position, movements between the metal sections (for example bending with respect to an axis vertical) will occur and create gaps between adjacent lamella metal profiles for fire, heat, smoke, etc.
The slats of the document DE19907801 even filled with intumescent material, are therefore incapable of forming a fire-resistant wall.

La prĆ©sente invention a pour objet une lamelle permettant de rĆ©aliser des portes anti feu assurant une rĆ©sistance optimale contre le passage des flammes (mĆŖme si la porte n'est pas abaissĆ©e de maniĆØre optimale), une meilleure rĆ©sistance au passage de la chaleur (la tempĆ©rature de la face de la porte opposĆ©e Ć  la face du cĆ“tĆ© de laquelle la flamme est appliquĆ©e reste plus longtemps Ć  une tempĆ©rature infĆ©rieure Ć  140Ā°C), et ce mĆŖme en cas de mouvements inadĆ©quats d'une lamelle par rapport Ć  une autre.The present invention relates to a blade for making fireproof doors ensuring optimum resistance against the passage of flames (even if the door is not lowered optimally), a better resistance to the passage of heat (temperature the side of the door opposite the side on which the flame is applied remains longer at a temperature below 140 Ā° C), even in case of inadequate movements of one lamella compared to another.

La lamelle selon l'invention permet en outre de rƩaliser des portes prƩsentant une rƩsistance amƩliorƩe Ơ l'effraction et/ou aux chocs et/ou au souffle d'une explosion.The slat according to the invention also makes it possible to produce doors having improved resistance to burglary and / or shock and / or blast explosion.

The lamella according to the invention is characterized:
    • in that the lamella further comprises a metal section extending in said casing so as to define two distinct chambers, namely a first chamber extending between the first longitudinal face and the metal section and a second longitudinal chamber extending between the second longitudinal face of the envelope and the metal profile, said first and second chambers being filled at least partially with an intumescent material,
    • in that the metal profile has a first longitudinal edge (26) adjacent to the first lateral face (23) of the envelope (20), and a second longitudinal edge (27) adjacent to the second lateral face (24) of the shell (20), said first edge (26) being profiled to define an open groove having an inner face of which at least a portion substantially corresponds to a section of a cylindrical face, while the second edge (27) is profiled to defining a longitudinal means whose outer face is adapted to be engaged at least partially in the open groove (26) of a first longitudinal edge of a metal section of an adjacent strip to form at least one means for pivoting at least along a longitudinal axis (A) between the considered lamella (2) and the adjacent lamella (2a) when said slats move along the at least partially curved guide path, and

In the lamella according to the invention, the metal section serves as a means for dividing the envelope into at least two distinct chambers (one being intended to be directed along one wall of the metal profile, while the other is intended to be directed along the other wall of the metal section). The metal profile also has one or more functions chosen from:
  • means for distributing the heat uniformly in the lamella,
  • means to prevent the passage of flames through the lamella and between two adjacent lamellae,
  • means of mechanical connection of the lamellae to each other,
  • means to distribute the heat more evenly between the different adjacent lamellae,
  • anti-burglary means,
  • means to slow the rise in temperature along the wall not exposed to fire,
  • means of resistance to the shock and / or the blast of an explosion,
  • means resistant to the passage of water, in particular in case of large water jet, for example a fire hose, and

On a de plus remarquĆ© que les lamelles selon l'invention permettaient dans des formes de rĆ©alisation, de rĆ©aliser des portes plus Ć©tanches aux fumĆ©es et permettant une adhĆ©rence des faces latĆ©rales des lamelles adjacentes le long de tous leurs bords longitudinaux, une fois la tempĆ©rature de ramollissement de la matiĆØre thermoplastique ou thermoformable atteinte.It has furthermore been noted that the lamellae according to the invention made it possible, in embodiments, to produce doors which are more smoke-tight and which allow adhesion of the lateral faces of the adjacent lamellae along all their longitudinal edges, once the temperature of the softening of the thermoplastic or thermoformable material reached.

Selon un dĆ©tail avantageux, le premier bord longitudinal (26) du profilĆ© mĆ©tallique prĆ©sente une extrĆ©mitĆ© courbe ou en crochet (51), tandis que le deuxiĆØme bord longitudinal (27) prĆ©sente une extrĆ©mitĆ© courbe ou en crochet (53), l'extrĆ©mitĆ© courbe ou en crochet (51) du premier bord longitudinal (26) du profilĆ© mĆ©tallique de la lamelle considĆ©rĆ©e Ć©tant adaptĆ©e pour ĆŖtre engagĆ©e dans l'extrĆ©mitĆ© courbe ou en crochet (53) d'un profilĆ© mĆ©tallique d'un deuxiĆØme bord longitudinal (27) d'une lamelle adjacente Ć  la lamelle considĆ©rĆ©e, lorsque la porte ou cloison est en position fermĆ©e, tandis que l'extrĆ©mitĆ© courbe ou en forme de crochet (53) du deuxiĆØme bord longitudinal (27) du profilĆ© mĆ©tallique de la lamelle considĆ©rĆ©e Ć©tant adaptĆ©e pour ĆŖtre engagĆ©e dans l'extrĆ©mitĆ© courbe ou en crochet (51) du profilĆ© mĆ©tallique d'un premier bord longitudinal (26) d'une autre lamelle adjacente Ć  la lamelle considĆ©rĆ©e, lorsque la porte ou cloison est en position fermĆ©e. Ceci permet d'assurer qu'en position fermĆ©e, les diffĆ©rents profilĆ©s mĆ©talliques des lamelles d'une porte forment une paroi sensiblement continue avec les profilĆ©s reliĆ©s les uns aux autres avec les bords longitudinaux en crochet de chaque profilĆ© d'une lamelle engagĆ©s dans et en contact avec un bord longitudinal en crochet de profilĆ©s mĆ©talliques de lamelles adjacentes.
Les bords longitudinaux en crochet des profilƩs mƩtalliques sont avantageusement adaptƩs pour que lorsque les lamelles de la porte en position fermƩe s'Ʃtendent dans un plan sensiblement vertical, les bords en crochet des profilƩs mƩtalliques s'opposent au retrait d'un profilƩ mƩtallique par rapport Ơ un profilƩ adjacent par un mouvement dans une direction perpendiculaire au plan sensiblement vertical de la porte ou paroi.
According to an advantageous detail, the first longitudinal edge (26) of the metal profile has a curved or hooked end (51), while the second longitudinal edge (27) has a curved or hooked end (53), the curved end or hook (51) of the first longitudinal edge (26) of the metal section of the lamella considered being adapted to be engaged in the curved or hooked end (53) of a metal section of a second longitudinal edge (27) a lamella adjacent to the lamella considered, when the door or partition is in the closed position, while the curved end or hook-shaped (53) of the second longitudinal edge (27) of the metal section of the lamella considered adapted to be engaged in the curved or hooked end (51) of the metal profile of a first longitudinal edge (26) of another lamella adjacent to the considered lamella, when the door or partition is in position. closed. This ensures that in the closed position, the different metal sections of the lamellae of a door form a substantially continuous wall with the sections connected to each other with the longitudinal hook edges of each section of a strip engaged in and in contact with a longitudinal hook edge of metal profiles of adjacent lamellae.
The longitudinal hook edges of the metal profiles are advantageously adapted so that when the slats of the door in the closed position extend in a substantially vertical plane, the hooked edges of the metal profiles oppose the withdrawal of a metal section relative to to an adjacent profile by a movement in a direction perpendicular to the substantially vertical plane of the door or wall.

Selon une particularitĆ©, les premiĆØre et deuxiĆØme faces latĆ©rales sont profilĆ©es de maniĆØre Ć  ce qu'en position fermĆ©e de la porte, la partie (23A) de la premiĆØre face latĆ©rale (23) s'Ć©tendant entre le profilĆ© mĆ©tallique (30) et la premiĆØre face longitudinale (21) prĆ©sente une portion adaptĆ©e pour toucher au moins une portion (24A) de la deuxiĆØme face latĆ©rale (24) s'Ć©tendant entre le profilĆ© mĆ©tallique (30) et la premiĆØre face longitudinale (21) d'une lamelle adjacente (2bis), tandis que la partie (24A) de la deuxiĆØme face latĆ©rale (24) de la lamelle considĆ©rĆ©e (2) s'Ć©tendant entre le profilĆ© mĆ©tallique (30) et la premiĆØre face longitudinale (21) prĆ©sente une portion (24A) adaptĆ©e pour toucher au moins une portion (23A) de la partie de la premiĆØre face latĆ©rale (23) s'Ć©tendant entre le profilĆ© mĆ©tallique (30) et la premiĆØre face longitudinale (21) d'une autre lamelle adjacente (2ter).
Ceci permet d'assurer une certaine ƩtanchƩitƩ supplƩmentaire de la porte le long d'une de ses faces, avantageusement cƓtƩ extƩrieure de la porte.
According to a feature, the first and second lateral faces are profiled so that in the closed position of the door, the portion (23A) of the first lateral face (23) extending between the metal section (30) and the first longitudinal face (21) has a portion adapted to touch at least a portion (24A) of the second lateral face (24) extending between the metal section (30) and the first longitudinal face (21) of an adjacent lamella (2a), whereas the portion (24A) of the second lateral face (24) of the considered lamella (2) extending between the metal section (30) and the first longitudinal face (21) has a portion (24A) adapted to touch at least a portion (23A) of the portion of the first side face (23) extending between the metal profile (30) and the first longitudinal face (21) of another adjacent lamella (2ter).
This ensures a certain additional sealing of the door along one of its faces, preferably outside the door.

Selon une autre particularitĆ©, l'enveloppe recouvre au moins partiellement le premier bord longitudinal et/ou au moins partiellement de deuxiĆØme bord longitudinal. Ceci permet d'assurer un meilleur accrochage de l'enveloppe au profilĆ© mĆ©tallique.
Dans des formes de rĆ©alisation, ceci permet Ć©galement d'Ć©viter un contact direct entre deux portions mĆ©talliques de deux lamelles diffĆ©rentes. De plus, en cas de dilatation des profilĆ©s mĆ©talliques due Ć  un incendie, la matiĆØre thermoplastique ou thermoformable prĆ©sente entre deux bords longitudinaux de deux lamelles adjacentes sera comprimĆ©e.
According to another feature, the envelope covers at least partially the first longitudinal edge and / or at least partially second longitudinal edge. This ensures a better attachment of the envelope to the metal profile.

Les profilĆ©s mĆ©talliques des lamelles sont ainsi protĆ©gĆ©s sur leurs deux faces opposĆ©es par un revĆŖtement continu formĆ© de chambres adjacentes contenant de la matiĆØre intumescente. Ceci assure une excellente protection contre le passage du feu, contre le passage de chaleur et contre le passage de fumĆ©es.According to a preferred embodiment, the side faces (23A, 23B) of a first chamber located along a first face of the metal profile and the side faces (24A, 24B) of a second chamber located along a second face of the metal profile opposite said first face of the metal section is adapted so that in the closed position of the door or partition, the first adjacent lamella chambers form a first continuous coating, while the second adjacent lamella chambers form a second continuous coating, the metal profiles of said adjacent lamellae extending between said first continuous coating and said second continuous coating.

La lamelle 2 comprend en outre un profilĆ© mĆ©tallique 30 s'Ć©tendant dans ladite enveloppe 20 de maniĆØre Ć  dĆ©finir deux chambres distinctes 20bis,20ter, Ć  savoir une premiĆØre chambre 20bis s'Ć©tendant entre la premiĆØre face longitudinale 21 et le profilĆ© mĆ©tallique 30 et une deuxiĆØme chambre 20ter longitudinale s'Ć©tendant entre la deuxiĆØme face longitudinale 22 de l'enveloppe 20 et le profilĆ© mĆ©tallique 30, lesdites premiĆØre et deuxiĆØme chambres 20bis, 20ter Ć©tant remplies au moins partiellement d'un matĆ©riau intumescent 25.The strip 2 further comprises a metal section 30 extending in said envelope 20 so as to define two separate chambers 20a, 20b, namely a first chamber 20a extending between the first longitudinal face 21 and the metal section 30 and a second longitudinal chamber 20ter extending between the second longitudinal face 22 of the casing 20 and the metal section 30, said first and second chambers 20a, 20ter being filled at least partially with an intumescent material 25.

Les extrƩmitƩs ouvertes de la lamelle 2 sont fermƩes par des capuchons ou couvercles 70 prƩsentant plusieurs pattes 71 de maintien destinƩes Ơ s'engager dans une des chambres 20bis,20ter, en particulier dans la couche intumescente 25. Chaque capuchon ou couvercle 70 est avantageusement muni d'un galet ou patin de guidage 72 adaptƩ pour suivre un chemin dƩfini par un rail ou une gorge.The open ends of the lamella 2 are closed by caps or lids 70 having a plurality of retaining tabs 71 intended to engage in one of the chambers 20a, 20b, in particular in the intumescent layer 25. Each cap or lid 70 is advantageously provided with a roller or guide shoe 72 adapted to follow a path defined by a rail or a groove.

Le profilĆ© mĆ©tallique 30 prĆ©sente un premier bord longitudinal 30bis (en forme de crochet) adjacent de la premiĆØre face latĆ©rale 23 de l'enveloppe 20, et un deuxiĆØme bord longitudinal 30 ter (en forme de crochet) adjacent de la deuxiĆØme face latĆ©rale 24 de l'enveloppe 20. Le premier bord 30bis est profilĆ© ou recourbĆ© pour dĆ©finir une gorge ouverte prĆ©sentant une face intĆ©rieure correspondant sensiblement Ć  une section d'une face cylindrique. Le deuxiĆØme bord 30ter est profilĆ© ou recourbĆ©e pour dĆ©finir un crochet longitudinal dont la face extĆ©rieure est adaptĆ©e pour ĆŖtre engagĆ©e au moins partiellement dans la gorge ouverte d'un premier bord longitudinal 30bis d'un profilĆ© mĆ©tallique 30 d'une lamelle adjacente. La liaison premier bord longitudinal - deuxiĆØme bord longitudinal 30bis - 30ter de deux lamelles adjacentes forme un moyen assurant un pivotement le long d'un axe longitudinal horizontal entre la lamelle considĆ©rĆ©e 2 et la lamelle adjacente 2bis ou 2ter lors du mouvement des dites lamelles le long du chemin de guidage au moins partiellement courbe.The metal profile 30 has a first longitudinal edge 30bis (hook-shaped) adjacent to the first side face 23 of the envelope 20, and a second longitudinal edge 30b (hook-shaped) adjacent to the second side face 24 of the the envelope 20. The first edge 30a is profiled or curved to define an open groove having an inner face substantially corresponding to a section of a cylindrical face. The second edge 30ter is profiled or curved to define a longitudinal hook whose outer face is adapted to be engaged at least partially in the open groove of a first longitudinal edge 30bis of a metal section 30 of an adjacent lamella. The first longitudinal edge connection - the second longitudinal edge 30bis - 30ter of two adjacent lamellae forms a means ensuring pivoting along a horizontal longitudinal axis between the lamella considered 2 and the lamella adjacent 2bis or 2ter during the movement of said strips along the guide path at least partially curved.

Les premiĆØre et deuxiĆØme faces latĆ©rales 23,24 sont profilĆ©es de maniĆØre Ć  ce qu'en position fermĆ©e de la porte 1, la partie 23A de la premiĆØre face latĆ©rale 23 s'Ć©tendant entre le profilĆ© mĆ©tallique 30 et la premiĆØre face longitudinale 21 prĆ©sente une portion adaptĆ©e pour toucher au moins une portion 24A de la partie de la deuxiĆØme face latĆ©rale 24 s'Ć©tendant entre le profilĆ© mĆ©tallique 30 et la premiĆØre face longitudinale 21 d'une lamelle adjacente 2bis, tandis que la partie 24A de la deuxiĆØme face latĆ©rale 24 de la lamelle considĆ©rĆ©e 2 s'Ć©tendant entre le profilĆ© mĆ©tallique 30 et la premiĆØre face longitudinale 21 prĆ©sente une portion adaptĆ©e pour toucher au moins une portion de la partie 23A de la premiĆØre face latĆ©rale 23 s'Ć©tendant entre le profilĆ© mĆ©tallique 30 et la premiĆØre face longitudinale 21 d'une autre lamelle adjacente 2ter.The first and second lateral faces 23, 24 are profiled so that in the closed position of the door 1, the portion 23A of the first lateral face 23 extending between the metal profile 30 and the first longitudinal face 21 has a portion adapted to touch at least a portion 24A of the portion of the second side face 24 extending between the metal section 30 and the first longitudinal face 21 of an adjacent strip 2a, while the portion 24A of the second side face 24 of the lamella considered 2 extending between the metal section 30 and the first longitudinal face 21 has a portion adapted to touch at least a portion of the portion 23A of the first side face 23 extending between the metal section 30 and the first longitudinal face 21 of another adjacent lamella 2ter.

L'enveloppe recouvre le premier bord longitudinal 30bis et le deuxiĆØme bord longitudinal 30ter (voir figure 8).The casing covers the first longitudinal edge 30bis and the second longitudinal edge 30ter (see figure 8 ).

L'enveloppe 20 est par exemple rƩalisƩe en PVC ou en polyamide.The envelope 20 is for example made of PVC or polyamide.

Pour faciliter le mouvement de rotation entre les bords longitudinaux 30bis,30ter d'une liaison entre deux lamelles adjacentes, au moins une surface en contact d'un bord longitudinal avec l'autre bord longitudinal est munie d'une couche ou revĆŖtement anti-friction, par exemple d'une couche en tĆ©flon ou en polyamide.To facilitate the rotational movement between the longitudinal edges 30bis, 30ter of a connection between two adjacent lamellae, at least one surface in contact with a longitudinal edge with the other longitudinal edge is provided with an anti-friction layer or coating for example a teflon or polyamide layer.

Les chambres 20bis,20ter sont remplies sensiblement complĆØtement avec une composition contenant un ou des matĆ©riaux intumescents 25.The chambers 20a, 20b are substantially completely filled with a composition containing one or more intumescent materials 25.

L'enveloppe et le profilĆ© mĆ©tallique sont par exemple associĆ©s l'un Ć  l'autre au moins par une co-extrusion de matiĆØre thermoplastique ou thermoformable par rapport au profilĆ© mĆ©tallique. Cette co-extrusion est par exemple rĆ©alisĆ©e un profilĆ© mĆ©tallique 30 dont le premier bord longitudinal et le deuxiĆØme bord longitudinal du profilĆ© sont profilĆ©s avant la coextrusion de matiĆØre thermoplastique ou thermoformable.
Ce profilĆ© mĆ©tallique 30 est introduit dans une filiĆØre 50 comportant des amenĆ©es 51 de matiĆØre thermoplastique fondue (sous pression) et des gorges intĆ©rieures ouvertes pour former l'enveloppe 20. Le profilĆ© mĆ©tallique 30 est avantageusement muni d'une couche de protection, en particulier d'une couche compatible avec la matiĆØre pour former l'enveloppe. Par exemple, le profilĆ© 30 est muni d'une couche de PVC avant d'ĆŖtre introduit dans la filiĆØre de co-extrusion ou de pultrusion.
The envelope and the metal section are for example associated with each other at least by a coextrusion of thermoplastic material or thermoformable with respect to the metal section. This coextrusion is for example carried out a metal section 30 whose first longitudinal edge and the second longitudinal edge of the profile are profiled before the coextrusion of thermoplastic or thermoformable material.
This metal profile 30 is introduced into a die 50 having feeds 51 of molten thermoplastic material (under pressure) and open inner grooves to form the envelope 20. The metal section 30 is advantageously provided with a protective layer, in particular a layer compatible with the material to form the envelope. For example, the profile 30 is provided with a PVC layer before being introduced into the coextrusion or pultrusion die.

Une fois l'enveloppe formĆ©e (sensiblement rigide pour garder sa forme), le profilĆ© muni de l'enveloppe arrive dans une portion de la filiĆØre oĆ¹ les parois de l'enveloppe 21 formĆ©e ne sont plus supportĆ©es par une face du cĆ“tĆ© intĆ©rieur de l'enveloppe. A ce moment, un produit intumescent est introduit sous pression via les amenĆ©es 52 pour remplir les deux chambres 20bis, 20ter.Once the casing is formed (substantially rigid to keep its shape), the section provided with the casing arrives in a portion of the die where the walls of the casing 21 formed are no longer supported by a face on the inside of the casing. 'envelope. At this time, an intumescent product is introduced under pressure via the feeds 52 to fill the two chambers 20a, 20b.

Avantageusement, le profilĆ© mĆ©tallique muni de l'enveloppe et de produit intumescent est tirĆ© hors de la filiĆØre (procĆ©dĆ© de pultrusion), effort de traction effectuĆ© sur les bords longitudinaux. Les lamelles sont alors dĆ©coupĆ©es Ć  la longueur dĆ©sirĆ©e.Advantageously, the metal section provided with the envelope and intumescent product is pulled out of the die (pultrusion process), tensile force performed on the longitudinal edges. The slats are then cut to the desired length.

Un autre procĆ©dĆ© de fabrication d'une lamelle selon l'invention est un procĆ©dĆ©, dans lequel on emboutit Ć  chaud une structure formĆ©e d'une premiĆØre coque 60 en matiĆØre thermoplastique ou thermoformable associĆ©e Ć  une couche de matiĆØre intumescente 61, d'un profilĆ© mĆ©tallique sensiblement plat 30, et d'une deuxiĆØme coque 63 en matiĆØre thermoplastique ou thermoformable associĆ©e Ć  une couche de matiĆØre intumescente 61, de maniĆØre Ć  former lesdits premier et deuxiĆØme bords longitudinaux 30bis,30ter des lamelles 2, et de donner la forme extĆ©rieure de l'enveloppe 20.Another method of manufacturing a lamella according to the invention is a method in which a structure formed of a first shell 60 made of thermoplastic or thermoformable material associated with a layer of intumescent material 61, a profile is heat-stamped. substantially flat metal 30, and a second shell 63 of thermoplastic or thermoformable material associated with a layer of intumescent material 61, so as to form said first and second longitudinal edges 30a, 30ter lamellae 2, and to give the outer shape of the envelope 20.

Les coques en matiĆØre thermoplastique ou thermoformable prĆ©sentent chacune des portions planes 66 sĆ©parĆ©es l'une de l'autre par une gouttiĆØre 67 munie de la couche intumescente 61, lesdites portions planes prĆ©sentant une largeur adaptĆ©e pour s'Ć©tendre au delĆ  des bords longitudinaux du profilĆ© mĆ©tallique avant emboutissage Ć  chaud.The shells made of thermoplastic or thermoformable material each have flat portions 66 separated from each other by a channel 67 provided with the intumescent layer 61, said flat portions having a width adapted to extend beyond the longitudinal edges of the profile. metal before hot stamping.

La figure 9 est une vue similaire Ơ celle de la figure 2. Dans cette forme de rƩalisation les lamelles 2 de la porte sont directement enroulƩes sur un tambour 8 dont la rotation est commandƩe par le moteur 9.The figure 9 is a view similar to that of the figure 2 . In this embodiment the slats 2 of the door are directly wound on a drum 8 whose rotation is controlled by the motor 9.

Dans cette forme de rĆ©alisation le tambour et son moteur sont portĆ©s par des supports 10 aptes Ć  coulisser entre des rails parallĆØles 70,71, en fonction de la quantitĆ© de lamelles enroulĆ©es. Le mouvement du support 10 est par exemple commandĆ© ou contrĆ“lĆ© par le moteur ou par la rotation de l'axe du tambour 8. Ceci permet d'assurer qu'une lamelle 2quater se trouve dans le plan des lamelles 2 de la porte obturant au moins partiellement le passage 5.In this embodiment the drum and its motor are carried by supports 10 slidable between parallel rails 70,71, depending on the amount of rolled slats. The movement of the support 10 is for example controlled or controlled by the motor or by the rotation of the axis of the drum 8. This ensures that a 2quater lamella is in the plane of the lamellas 2 of the closing door at least partially the passage 5.

La figure 10 est une vue partielle en coupe de trois lamelles 2bis, 2, 2 ter de la porte de la figure 9.The figure 10 is a partial sectional view of three strips 2bis, 2, 2 ter of the door of the figure 9 .

Les lamelles comprennent un profilĆ© mĆ©tallique 30 prĆ©sentant un bord longitudinal infĆ©rieur 30bis et un bord longitudinal supĆ©rieur 30ter. Le profilĆ© mĆ©tallique 30 est associĆ© sur une de ses faces avec une premiĆØre chambre 20bis dĆ©finie par des parois 21, 23A, 24A,30A en matiĆØre thermoplastique, chambre remplie de matiĆØre intumescente, et sur l'autre de ses faces avec une deuxiĆØme chambre 20ter dĆ©finie par les parois 22, 24B,23B et 30B.The lamellae comprise a metal section 30 having a lower longitudinal edge 30a and an upper longitudinal edge 30b. The metal section 30 is associated on one of its faces with a first chamber 20a defined by walls 21, 23A, 24A, 30A of thermoplastic material, chamber filled with intumescent material, and on the other of its faces with a second chamber 20ter defined by the walls 22, 24B, 23B and 30B.

Les chambres 20bis, 20ter sont adaptĆ©es de maniĆØre Ć  ce qu'en position fermĆ©e de la porte, la paroi 23A de la lamelle 2 touche la paroi 24A de la lamelle 2bis adjacente (situĆ©e en dessous de la lamelle 2), la paroi 24A de la lamelle 2 touche la paroi 23A de la lamelle 2ter adjacente, situĆ©e au dessus de la lamelle 2, une partie de la paroi 23B de la lamelle 2 touche une portion de la paroi 24B de la lamelle adjacente 2bis situĆ©e en dessous de la lamelle 2 et enfin, une portion de la paroi 24B de la lamelle 2 touche une partie de la paroi 23B de la lamelle 2ter adjacente et situĆ©e au dessus de la lamelle 2.The chambers 20a, 20b are adapted so that in the closed position of the door, the wall 23A of the lamella 2 touches the wall 24A of the adjacent lamella 2a (located below the lamella 2), the wall 24A of the the lamella 2 touches the wall 23A of the adjacent lamella 2ter, situated above the lamella 2, a part of the wall 23B of the strip 2 touches a portion of the wall 24B of the adjacent strip 2bis located below the strip 2 and finally, a portion of the wall 24B of the strip 2 touches a portion of the wall 23B of the lamella 2ter adjacent and located above the lamella 2.

Les bords longitudinaux 30bis, 30ter des lamelles 2,2bis,2ter sont profilƩs pour permettre un mouvement d'Ʃcartement des lamelles entre elles (par exemple par translation) lors de l'ouverture de la porte.
Le bord longitudinal 30bis (infƩrieur) dƩfinit une gorge 50 sensiblement ou partiellement en U se terminant par une extrƩmitƩ en forme de crochet 51 tournƩ vers la gorge 50. Le bord longitudinal 30ter (supƩrieur) dƩfinit une gorge 52 se terminant par une extrƩmitƩ en crochet 53 tournƩ vers la gorge 52.
La partie de la gorge 50 situĆ©e en dessous du crochet 51 d'une lamelle 2 est adaptĆ©e pour recevoir au moins partiellement le crochet 53 d'un bord longitudinal 30ter d'une autre lamelle 2bis. Le crochet 53 coopĆØre ainsi avec le crochet 51 pour maintenir les lamelles les une aux autres lors de mouvements relatifs entre les lamelles.
The longitudinal edges 30a, 30b of the lamellae 2.2a, 2b are profiled to allow a spacing movement of the lamellae between them (for example by translation) during the opening of the door.
The longitudinal edge 30a (bottom) defines a substantially U-shaped groove 50 ending in a hook-shaped end 51 facing the groove 50. The longitudinal edge 30ter (upper) defines a groove 52 ending in a hook end 53 facing the throat 52.
The portion of the groove 50 located below the hook 51 of a strip 2 is adapted to receive at least partially the hook 53 of a longitudinal edge 30ter of another lamella 2a. The hook 53 thus cooperates with the hook 51 to hold the slats to each other during relative movements between the slats.

Dans la porte ou cloison en position fermĆ©e de la figure 10, les faces latĆ©rales (23A,23B) d'une premiĆØre chambre situĆ©e le long d'une premiĆØre face du profilĆ© mĆ©tallique et les faces latĆ©rales (24A,24B) d'une deuxiĆØme chambre situĆ©e le long d'une deuxiĆØme face du profilĆ© mĆ©tallique opposĆ©e Ć  ladite premiĆØre face du profilĆ© mĆ©tallique des lamelles sont adaptĆ©es pour qu'en position fermĆ©e de la porte ou cloison, les premiĆØres chambres de lamelles adjacentes forment un premier revĆŖtement continu (formĆ© de chambres remplies de matiĆØres intumescentes, chambres se touchant l'une l'autre par leurs faces latĆ©rales en contact avec de la matiĆØre intumescente), tandis que les deuxiĆØmes chambres de lamelles adjacentes forment un deuxiĆØme revĆŖtement continu (formĆ© de chambres remplies de matiĆØres intumescentes, chambres se touchant l'une l'autre par leurs faces latĆ©rales en contact avec de la matiĆØre intumescente), les profilĆ©s mĆ©talliques desdites lamelles adjacentes s'Ć©tendant entre ledit premier revĆŖtement continu et ledit deuxiĆØme revĆŖtement continu. Les profilĆ©s mĆ©talliques des lamelles sont ainsi protĆ©gĆ©s sur leurs deux faces opposĆ©es par un revĆŖtement continu formĆ© de chambres adjacentes contenant de la matiĆØre intumescente. Ceci assure une excellente protection contre le passage du feu, contre le passage de chaleur et contre le passage de fumĆ©es.In the door or partition in the closed position of the figure 10 , the side faces (23A, 23B) of a first chamber located along a first face of the metal profile and the side faces (24A, 24B) of a second chamber located along a second face of the metal section opposed to said first face of the metal section of the lamellae are adapted so that in the closed position of the door or partition, the first adjacent lamella chambers form a first continuous coating (formed of chambers filled with intumescent materials, chambers touching one the other by their lateral faces in contact with the intumescent material), while the second chambers of adjacent lamellae form a second continuous coating (formed of chambers filled with intumescent materials, chambers touching each other by their faces side contacts with intumescent material), the metal profiles of said adjacent lamellae extending between said first coating continuous and said second continuous coating. The metal sections of the slats are thus protected on their two opposite faces by a continuous coating formed of adjacent chambers containing intumescent material. This provides excellent protection against the passage of fire, against the passage of heat and against the passage of fumes.

Lors de l'ouverture de la porte, les lamelles 2,2bis,2ter s'Ć©cartent les unes des autres, grĆ¢ce au mouvement de translation du crochet 53 dans la portion de la gorge 50 situĆ©e sous le crochet 51. Le mouvement de translation est limitĆ© lorsque le bas du crochet 53 vient buter contre le fond 50A de la gorge 50.When opening the door, the lamellae 2.2a, 2ter deviate from each other, thanks to the translational movement of the hook 53 in the portion of the groove 50 located under the hook 51. The translational movement is limited when the bottom of the hook 53 abuts against the bottom 50A of the groove 50.

Le fond de la gorge 50 prƩsente au moins une portion courbe 50B (portion d'une surface cylindrique, par exemple le quart d'une surface cylindrique), tandis que le crochet 53 prƩsente une forme courbe 53A adaptƩe pour Ʃpouser au moins partiellement la portion courbe 50B de la gorge 50. La forme courbe 53A correspond par exemple au moins Ơ la moitiƩ d'une surface cylindrique.
Ceci permet alors un pivotement Ć©ventuel d'une lamelle par rapport Ć  une autre lamelle par un mouvement de glissement (rotatif) de la face 53A le long de la face 50B.
Le mouvement de rotation des lamelles entre elles est toutefois limitƩ par le contact d'une face intƩrieure de la gorge 52 sur une face extƩrieure du crochet 51. (voir figure 12)
The bottom of the groove 50 has at least one curved portion 50B (portion of a cylindrical surface, for example a quarter of a cylindrical surface), while the hook 53 has a curved shape 53A adapted to fit at least partially the portion 50B curve of the groove 50. The curved shape 53A corresponds for example to at least half of a cylindrical surface.
This then allows a possible pivoting of a sipe with respect to another sipe by a sliding movement (rotary) of the face 53A along the face 50B.
The movement of rotation of the lamellae between them is however limited by the contact of an inner face of the groove 52 on an outer face of the hook 51. (see figure 12 )
