Abstract

Two substantially symmetrical half-slats are joined by an integral flexible joint to form a one-piece articulated slat. Adjacent slats rigidly interlock by cooperation of a projecting rib on one slat and a correspondingly shaped groove on the other slat to form an articulated curtain. The flexible joints are bendable in two directions and coextruded with the half-slats.

Description

L'invention concerne une lame profilée pour fermeture à rideau et le rideau de fermeture correspondant.The invention relates to a profiled blade for curtain closing and the corresponding closing curtain.

Il est connu par le document FR-A-2 582 715 de réaliser une fermeture à rideau au moyen de lames profilées présentant sur un bord longitudinal un élément d'articulation mâle en cylindre fermé et sur le bord opposé un élément d'articulation femelle en cylindre ouvert. Ces deux éléments sont adaptés pour coopérer avec les éléments correspondants des lames adjacentes. Lorsque le rideau est fermé, sa face frontale est sensiblement plane, et les bords frontaux de deux lames adjacentes ne sont séparées que par une fente étroite.Document FR-A-2 582 715 discloses a curtain closure by means of profiled blades having on a longitudinal edge a male articulation element in a closed cylinder and on the opposite edge a female articulation element in open cylinder. These two elements are adapted to cooperate with the corresponding elements of the adjacent blades. When the curtain is closed, its front face is substantially flat, and the front edges of two adjacent blades are only separated by a narrow slot.

Cependant, lorsque les lames du rideau pivotent l'une par rapport à l'autre, les éléments d'articulation autorisent un large écartement des deux bords frontaux de deux lames adjacentes. Il s'ensuit une impossibilité de recouvrir la face frontale du rideau avec un tissu ou un papier décoratif qui serait déchiré à la première ouverture du rideau.However, when the curtain blades pivot relative to each other, the articulation elements allow a wide separation of the two front edges of two adjacent blades. It follows that it is impossible to cover the front face of the curtain with a fabric or decorative paper which would be torn when the curtain is opened for the first time.

L'un des buts de la présente invention est de proposer un rideau de fermeture à lames articulées, dont la face frontale garde sensiblement la même surface quelle que soit la position des lames.One of the aims of the present invention is to provide a closing curtain with articulated blades, the front face of which keeps substantially the same surface whatever the position of the blades.

Un autre but de l'invention est de proposer des lames pour rideau de fermeture susceptibles d'être articulées en faisant un angle pouvant aller jusqu'à 60° environ.Another object of the invention is to provide blades for a closing curtain capable of being articulated at an angle of up to approximately 60 °.

La présente invention a pour objet une lame profilée pour fermeture à rideau caractérisée en ce qu'elle est constituée de deux demi-lames sensiblement symétriques, réunies par un joint souple.The subject of the present invention is a profiled strip for curtain closure, characterized in that it consists of two substantially symmetrical half-strips, joined by a flexible joint.

Selon d'autres caractéristiques de l'invention:
- les demi-lames et le joint sont coextrudés.
- chaque demi-lame présente en coupe transversale un contour polygonal comprenant un premier côté correspondant à la face frontale de la lame et un deuxième côté perpendiculaire au premier et correspondant à la face latérale de la lame.
- le contour polygonal de chaque demi-lame présente, au droit du joint, un angle aigu entre ledit premier côté et un quatrième côté, lesdits quatrièmes côtés des deux demi-lames d'une même lame faisant entre eux un angle d'environ 60°.
- ledit quatrième côté est séparé d'un troisième côté par un angle sensiblement droit dont la paroi externe assure seule l'appui de chaque demi-lame sur la glissière.
- ledit deuxième côté d'une demi-lame porte une nervure et ledit deuxième côté de l'autre demi-lame porte une rainure de sorte que deux demi-lames adjacentes de deux lames adjacentes soient solidarisées par la coopération de la nervure et de la rainure.
- le joint souple présente sur sa face avant une rainure en V dont l'angle d'ouverture est d'environ 90°.According to other characteristics of the invention:
- the half-blades and the joint are coextruded.
- Each half-blade has in cross section a polygonal contour comprising a first side corresponding to the front face of the blade and a second side perpendicular to the first and corresponding to the side face of the blade.
- The polygonal contour of each half-blade has, at the right of the joint, an acute angle between said first side and a fourth side, said fourth sides of two half-blades of the same blade forming an angle of about 60 °.
- Said fourth side is separated from a third side by a substantially right angle, the outer wall of which alone provides support for each half-blade on the slide.
- Said second side of a half-blade carries a rib and said second side of the other half-blade carries a groove so that two adjacent half-blades of two adjacent blades are secured by the cooperation of the rib and the groove.
- The flexible seal has a V-shaped groove on its front face, the opening angle of which is approximately 90 °.

L'invention a également pour objet un rideau de fermeture à lames caractérisé en ce qu'il est constitué de lames liées rigidement entre elles, l'articulation se faisant au milieu de chaque lame au moyen d'un joint souple.The invention also relates to a shutter curtain with blades, characterized in that it consists of blades rigidly linked together, the articulation being made in the middle of each blade by means of a flexible joint.

D'autres caractéristiques ressortent de la description qui suit faite avec référence au dessin annexé sur lequel on peut voir :

  • Figure 1 : une vue schématique en coupe transversale d'un exemple de réalisation d'une lame profilée pour fermeture à rideau selon l'invention;
  • Figure 2 : une vue agrandie du joint souple d'articulation de la lame de la figure 1 ;
  • Figure 3 : une vue en coupe transversale d'un exemple de réalisation d'un rideau de fermeture disposé dans une glissière.
Other characteristics appear from the following description made with reference to the attached drawing on which we can see:
  • Figure 1: a schematic cross-sectional view of an embodiment of a profiled blade for curtain closure according to the invention;
  • Figure 2: an enlarged view of the flexible joint of the blade of Figure 1;
  • Figure 3: a cross-sectional view of an exemplary embodiment of a closing curtain arranged in a slide.

En se reportant à la figure 1, on voit que la lame selon l'invention est constituée de deux demi-lames 1 et 2 réunies par un joint souple 3. Chaque demi-lame est creuse et obtenue par extrusion d'un profilé en matière plastique par exemple. Chaque demi-lame présente, en coupe transversale, un contour polygonal présentant un angle aigu au droit du joint 3 c'est-à-­dire vers le milieu de la lame.Referring to FIG. 1, it can be seen that the blade according to the invention consists of two half-blades 1 and 2 joined by a flexible joint 3. Each half-blade is hollow and obtained by extruding a profile of material plastic for example. Each half-blade has, in cross section, a polygonal contour having an acute angle to the right of the joint 3, that is to say towards the middle of the blade.

A partir de cet angle aigu 4, le contour polygonal de la demi-lame 2 comporte un premier côté 5 correspondant à la face frontale de la lame, un angle droit 6, un deuxième côté 7 correspondant à la face latérale de la lame, un angle obtus 8, un troisième côté 9, un angle sensiblement droit 10 et un quatrième côté 11. De cette manière, l'angle sensiblement droit 10 se trouve le point le plus éloigné du premier côté 5. Lorsque le rideau de fermeture se déplace dans une glissière, la paroi extérieure de cet angle 10 assure seule l'appui de la demi-lame sur la glissière, ce qui réduit les frottements.From this acute angle 4, the polygonal contour of the half-blade 2 has a first side 5 corresponding to the front face of the blade, a right angle 6, a second side 7 corresponding to the side face of the blade, a obtuse angle 8, a third side 9, a substantially right angle 10 and a fourth side 11. In this way, the substantially right angle 10 is the point furthest from the first side 5. When the closing curtain moves in a slide, the outer wall of this angle 10 ensures only the support of the half-blade on the slide, which reduces friction.

A l'extérieur de la demi-lame 2, le deuxième côté 7 porte une nervure 12 en T destinée à coopérer avec une rainure 13 correspondante de la demi-lame adjacente qui est identique à la demi-lame 1.On the outside of the half-blade 2, the second side 7 carries a T-shaped rib 12 intended to cooperate with a corresponding groove 13 of the adjacent half-blade which is identical to the half-blade 1.

La demi-lame 1 est sensiblement symétrique de la demi-­lame 2 par rapport au plan médian passant par le joint 3. Elle présente, en coupe, un contour polygonal avec un angle aigu 14, un premier côté 15, un angle droit 16, un deuxième côté 17, un angle obtus 18, un troisième côté 19, un angle sensiblement droit 20, et un quatrième côté 21. Le deuxième côté 17 porte une rainure 13 en T, limitée vers l'intérieur de la demi-­lame 1 par une cloison 22.The half-blade 1 is substantially symmetrical with the half-blade 2 with respect to the median plane passing through the joint 3. It has, in section, a polygonal contour with an acute angle 14, a first side 15, a right angle 16, a second side 17, an obtuse angle 18, a third side 19, a substantially right angle 20, and a fourth side 21. The second side 17 carries a T-shaped groove 13, limited towards the inside of the half-blade 1 by a partition 22.

Une demi-lame telle que 2 est solidarisée à la demi-­lame adjacente, telle que 1, par insertion de sa nervure en T 12 dans la rainure en T 13 correspondante. Les lames du rideau de fermetures sont ainsi solidarisées les unes aux autres au moyen des nervures 12 et des rainures 13. Les rainures sont dimensionnées pour que les nervures y glissent à frottement doux. Deux lames adjacentes sont ainsi solidarisées de façon efficace et l'articulation du rideau se fait au moyen des joints 3, c'est-à-dire au milieu des lames. L'angle entre les deux quatrièmes côtés 11 et 21 des deux demi-­lames 2 et 1 respectivement, est d'environ 60°, ce qui permet un angle de pliage d'environ 60° d'une demi-lame sur l'autre vers l'arrière.A half-blade such as 2 is secured to the adjacent half-blade, such as 1, by insertion of its T-rib 12 in the corresponding T-groove 13. The blades of the closure curtain are thus secured to one another by means of the ribs 12 and the grooves 13. The grooves are dimensioned so that the ribs slide therein with gentle friction. Two adjacent blades are thus effectively secured and the articulation of the curtain is done by means of the seals 3, that is to say in the middle of the blades. The angle between the two fourth sides 11 and 21 of the two half-blades 2 and 1 respectively, is approximately 60 °, which allows a folding angle of approximately 60 ° from one half-blade to the other rearward.

Sur la figure 2, on voit que le joint 3 est disposé entre les deux côtés en regard 11 et 21, au voisinage immédiat des angles aigus 4 et 14 des deux demi-lames. Ce joint peut être collé sur les deux demi-lames, mais il est avantageusement coextrudé avec les deux demi-­lames. Il est souple et plastique pour être déformable élastiquement .In Figure 2, we see that the seal 3 is disposed between the two opposite sides 11 and 21, in the immediate vicinity of the acute angles 4 and 14 of the two half-blades. This joint can be glued to the two half-blades, but it is advantageously coextruded with the two half-blades. It is flexible and plastic to be elastically deformable.

De préférence, il présente sur la face frontale de la lame, une rainure 23 en V dont l'angle d'ouverture est d'environ 90°. Ce joint 3 permet le pliage de la lame tant vers l'arrière (cas de la figure 3) que vers l'avant. Lorsque la lame est pliée vers l'arrière, la rainure 23 en V assure que le joint ne fasse pas de saillie vers l'avant. De cette manière, l'ensemble de la face frontale du rideau peut être revêtu d'un tissu ou d'un papier qui ne se déchire pas au cours des manoeuvres d'ouverture ou de fermeture du rideau. L'apparence esthétique du rideau est ainsi améliorée par rapport à un rideau classique à lamelles articulées les unes sur les autres par des tourillons ne permettant pas la pose d'un revêtement continu.Preferably, it has on the front face of the blade, a V-shaped groove 23 whose opening angle is about 90 °. This joint 3 allows the folding of the blade both backwards (as in Figure 3) and forward. When the blade is folded back, the V-shaped groove 23 ensures that the joint does not protrude forward. In this way, the entire front face of the curtain can be covered with a fabric or paper which does not tear during the opening or closing operations of the curtain. The aesthetic appearance of the curtain is thus improved compared to a conventional curtain with lamellas hinged on each other by pins which do not allow the laying of a continuous covering.

Le rideau selon l'invention, constitué de demi-lames creuses coextrudées avec leur joint d'articulation se comporte comme un rideau rigide à double paroi, les joints souples assurant l'articulation.The curtain according to the invention, consisting of hollow half-blades coextruded with their articulation joint behaves like a rigid curtain with double wall, the flexible joints ensuring articulation.

Les lames articulées étant obtenues par coextrusion, peuvent être coupées à la longueur voulue et assemblées entre elles pour constituer un rideau de dimensions déterminées.The articulated blades being obtained by coextrusion, can be cut to the desired length and assembled together to form a curtain of determined dimensions.

A la différence des rideaux classiques à lamelles articulées par tourillons, le rideau selon l'invention est susceptible de s'articuler dans les deux sens.Unlike traditional curtains with lamellas articulated by pins, the curtain according to the invention is capable of being articulated in both directions.

Les exemples de réalisation décrits aux figures 1 et 2 ne sont qu'illustratifs et on peut remplacer les nervures et rainures en T par tout type de fixation, à tenon et mortaise par exemple.The embodiments described in Figures 1 and 2 are only illustrative and we can replace the ribs and T-slots by any type of fixing, tenon and mortise for example.

Avec le rideau à lames selon l'invention, le bruit lié au fonctionnement du rideau est très réduit et on peut noter une grande souplesse de fonctionnement.With the louvre curtain according to the invention, the noise linked to the operation of the curtain is very reduced and a great flexibility of operation can be noted.
