Description

La présente invention est relative à un dispositif d'attache de tablier pour volet roulant destiné à équiper une ouverture telle qu'une porte ou une fenêtre comportant un arbre monté à rotation sur un support, le dispositif d'attache comportant une barrette flexible dont une première extrémité est liée à l'arbre et une seconde extrémité comportant un renflement est liée au bord supérieur d'un tablier composé de lames articulées, des lames du tablier appuyant sur le dispositif d'attache lors de l'enroulement du tablier autour de l'arbre.The present invention relates to a roller shutter attachment device for fitting an opening such as a door or a window comprising a shaft mounted to rotate on a support, the attachment device comprising a flexible bar including a first end is connected to the shaft and a second end having a bulge is connected to the upper edge of an apron composed of articulated blades, blades of the apron pressing on the fastening device during the winding of the apron around the 'tree.

Pendant la durée de vie du volet roulant, le nombre de déroulements et d'enroulements des lames du tablier autour de l'arbre augmentant, on constate l'apparition de marques sur les lames, provoquées par le contact des lames avec le dispositif d'attache. En outre, l'extrémité du dispositif d'attache destinée à être liée au bord supérieur du tablier comporte généralement un renflement.During the lifetime of the shutter, the number of unwindings and windings of the apron blades around the tree increases, there is the appearance of marks on the blades, caused by the contact of the blades with the device of attached. In addition, the end of the attachment device intended to be connected to the upper edge of the deck generally has a bulge.

Lors de l'enroulement, la première couche de lames est plaquée contre la barrette flexible et le renflement par la seconde couche de lames, ce qui entraîne la formation de marques.During winding, the first layer of blades is pressed against the flexible bar and the bulge by the second layer of blades, resulting in the formation of marks.

D'une manière générale, le dispositif d'attache du tablier sur l'arbre comporte souvent des aspérités susceptibles de provoquer des marques sur les lames du tablier lors de l'enroulement.In general, the attachment device of the deck on the shaft often has roughnesses that may cause marks on the apron blades during winding.

Dans le cas où le tablier se trouve du côté extérieur de l'arbre, les marques provoquées sur les lames seront visibles depuis l'intérieur du bâtiment lorsque le tablier est déroulé, ce qui nuit à l'aspect du volet roulant.In the case where the deck is on the outside of the tree, the marks caused on the blades will be visible from inside the building when the deck is unrolled, which affects the appearance of the shutter.

Le dispositif d'attache est soumis par ailleurs à de nombreuses contraintes de conception. Sa flexibilité doit être suffisante pour permettre son enroulement autour de l'arbre et ses propriétés mécaniques doivent lui permettre de supporter de nombreux cycles enroulement/déroulement malgré l'effort dû au poids des lames du tablier. Ce dernier point interdit de diminuer le volume du dispositif d'attache.The attachment device is also subject to many design constraints. Its flexibility must be sufficient to allow its winding around the shaft and its mechanical properties must allow it to withstand many cycles winding / unwinding despite the effort due to the weight of the apron blades. This last point prohibits decreasing the volume of the fastening device.

DE 94 12 134 U1 propose une couche de revêtement floconneux sur la face concernée de la barrette d'attache pour éviter des marques sur la face intérieure du tablier de volet roulant. La mise en place de ce revêtement nécessite un traitement particulier de la barrette. DE 94 12 134 U1 proposes a layer of flaky coating on the relevant face of the fastening bar to avoid marks on the inner face of the rolling shutter apron. The establishment of this coating requires special treatment of the bar.

L'invention a pour but, surtout, de proposer un dispositif d'attache pour tablier de volet roulant ainsi qu'un volet roulant comportant un tel dispositif d'attache, permettant d'éviter un traitement particulier de la barrette tout en empêchant la formation de marques disgracieuses sur la face intérieure du tablier.The object of the invention is, above all, to propose a fastening device for roller blind apron and a shutter comprising such a device. attachment, avoiding special treatment of the bar while preventing the formation of unsightly marks on the inside of the deck.

Selon l'invention un dispositif d'attache de tablier pour volet roulant du genre défini précédemment comporte un moyen de protection interposé entre les lames et le dispositif d'attache, et est caractérisé en ce que le moyen de protection est réalisé sous la forme d'une poche dans laquelle est insérée la barrette flexible.According to the invention a roller shutter attachment device of the kind defined above comprises a protective means interposed between the blades and the attachment device, and is characterized in that the protection means is embodied in the form of a pocket in which is inserted the flexible bar.

La poche peut avoir la forme d'un T, la barre transversale du T recevant le renflement du dispositif d'attache.The pocket may be in the form of a T, the transverse bar of the T receiving the bulge of the fastening device.

Avantageusement la poche présente une section rectangulaire constante et est prolongée au niveau de la pince par des languettes d'une largeur correspondant sensiblement à celle de la poche.Advantageously, the pocket has a constant rectangular section and is extended at the level of the clip by tabs of a width substantially corresponding to that of the pocket.

La poche peut être réalisée en PVC. L'épaisseur des parois de la poche peut être comprise entre 100 et 150 µm.The pocket can be made of PVC. The thickness of the walls of the pocket may be between 100 and 150 microns.

Le moyen de protection peut couvrir seulement la partie centrale de la zone du dispositif d'attache solidaire du tablier, ou bien en variante la quasi-totalité de la barrette flexible ainsi que toute la zone du dispositif d'attache solidaire du tablier.The protection means may cover only the central part of the zone of the fastening device secured to the apron, or alternatively substantially all of the flexible bar and the entire area of the fastening device integral with the deck.

Le moyen de protection peut aussi couvrir la quasi totalité de la surface du dispositif d'attache.The protection means can also cover almost the entire surface of the attachment device.

Selon l'invention, un volet roulant est caractérisé en ce qu'il comporte un dispositif d'attache tel que décrit précédemment.According to the invention, a roller shutter is characterized in that it comprises a fastening device as described above.

D'autres caractéristiques et avantages de l'invention apparaîtront dans la description qui suit d'un mode de réalisation avec référence aux dessins annexés mais qui n'a aucun caractère limitatif.Other features and advantages of the invention will appear in the following description of an embodiment with reference to the accompanying drawings but which has no limiting character.

En se référant à Fig. 1 et Fig. 2, on peut voir un arbre 1 monté à rotation sur un support non représenté. L'arbre 1 possède une section globalement circulaire et est réalisé en métal embouti. Des fentes 1a sont prévues alignées le long d'une génératrice de la surface de l'arbre 1, parallèlement à son axe.To refer at Fig. 1 and FIG. 2 , we can see a tree 1 mounted at rotation on a support not shown. The shaft 1 has a generally circular section and is made of stamped metal. Slots 1a are provided aligned along a generatrix of the surface of the shaft 1, parallel to its axis.

L'arbre 1 est relié à un tablier 2 composé de lames 3, articulées entre elles, par l'intermédiaire d'un dispositif d'attache 4. Le dispositif d'attache 4, illustré notamment par Fig. 3 et Fig. 4, comporte une barrette flexible 5 ou feuillard en forme de bande issue d'une feuille métallique comportant une première extrémité 5a et une seconde extrémité 5b.The shaft 1 is connected to an apron 2 composed of blades 3, hinged together by means of a fastening device 4. The fastening device 4, illustrated in particular by Fig. 3 and FIG. 4 , comprises a flexible strip 5 or sheet-shaped strip formed from a metal sheet having a first end 5a and a second end 5b.

La première extrémité 5a comporte deux encoches 5c disposées face à face de part et d'autre de l'axe longitudinal A de la barrette flexible 5. Les encoches 5c comportent un profil qui, selon une vue de dessus, est composé d'un premier segment rectiligne perpendiculaire à l'axe longitudinal A et d'un second segment correspondant à un quart de cercle.The first end 5a has two notches 5c disposed face to face on either side of the longitudinal axis A of the flexible bar 5. The notches 5c comprise a profile which, in a view from above, is composed of a first rectilinear segment perpendicular to the longitudinal axis A and a second segment corresponding to a quarter circle.

La première extrémité 5a comporte également une fente longitudinale médiane 5d séparant l'extrémité 5a en deux portions symétriques par rapport à l'axe longitudinal.The first end 5a also has a central longitudinal slot 5d separating the end 5a into two portions symmetrical with respect to the longitudinal axis.

La seconde extrémité 5b est solidaire d'un renflement transversal formé par une pince 6. La pince 6 est réalisée notamment en matériau polymère. La pince 6 comporte une section sensiblement constante dans un plan P orthogonal au plan de la barrette 5 et parallèle à la fente 5d comme illustré sur Fig. 4.The second end 5b is integral with a transverse bulge formed by a clamp 6. The clamp 6 is made in particular of polymer material. The clamp 6 has a substantially constant section in a plane P orthogonal to the plane of the bar 5 and parallel to the slot 5d as illustrated in FIG. Fig. 4 .

Dans une telle section, la pince 6 a sensiblement la forme d'un U renversé, la base du U comportant un premier prolongement en direction de la seconde extrémité 5b. L'une des branches du U comporte un second prolongement s'étendant sensiblement orthogonalement à cette branche, vers l'intérieur du U.In such a section, the clamp 6 has substantially the shape of an inverted U, the base of the U having a first extension in the direction of the second end 5b. One of the branches of the U comprises a second extension extending substantially orthogonally to this branch, towards the inside of the U.

Selon l'invention, un moyen de protection M est mis en place autour du dispositif d'attache 4. Le moyen de protection M est réalisé sous la forme d'une poche 7 qui est mise en place autour de la barrette flexible 5 et de la pince 6. La poche 7 a sensiblement la forme d'un T renversé selon Fig. 3 et 4. Deux soudures en forme de L sont réalisées de part et d'autre de la barre longitudinale du T. La poche 7 épouse les formes de la barrette flexible 5 et de la pince 6 reçue dans la barre transversale du T. La poche 7 est réalisée à partir d'un film en PVC dont l'épaisseur est comprise entre 100 et 150 µm.According to the invention, a protection means M is placed around the fastening device 4. The protection means M is in the form of a pocket 7 which is placed around the flexible strip 5 and the clip 6. The pocket 7 has substantially the shape of an inverted T according to Fig. 3 and 4 . Two L-shaped welds are made on both sides of the longitudinal bar T. The pocket 7 matches the shapes of the flexible bar 5 and the clamp 6 received in the transverse bar T. The pocket 7 is made from a PVC film whose thickness is between 100 and 150 μm.

La poche 7 comporte une première ouverture 7a permettant le passage de la première extrémité 5a.The pocket 7 has a first opening 7a allowing the passage of the first end 5a.

La poche 7 comporte également une seconde ouverture 7b au niveau de la pince 6 afin de ne pas gêner la fixation de la pince 6 sur le bord supérieur du tablier 2. Dans le même but, au niveau de la seconde ouverture 7b, les deux feuilles de PVC formant la poche 7 sont reliées uniquement le long du bord supérieur de la barre transversale du T par une soudure interrompue en partie centrale pour permettre le passage de la barrette flexible 5.The pocket 7 also has a second opening 7b at the clamp 6 so as not to interfere with the attachment of the clamp 6 on the upper edge of the apron 2. For the same purpose, at the second opening 7b, the two sheets PVC forming the pocket 7 are connected only along the upper edge of the transverse bar of the T by a weld interrupted in the central part to allow the passage of the flexible bar 5.

Pour le montage, lors d'une première étape, la poche 7 est mise en place sur la barrette flexible 5 et la pince 6. A cette fin l'extrémité 5a est engagée dans la seconde ouverture 7b, puis dans la partie verticale de la poche 7, pour sortir par l'ouverture 7a. La pince 6 vient se loger entre les parois de la barre transversale horizontale de la poche 7.For assembly, in a first step, the pocket 7 is placed on the flexible bar 5 and the clamp 6. To this end the end 5a is engaged in the second opening 7b, then in the vertical part of the pocket 7, to exit through the opening 7a. The clamp 6 is housed between the walls of the horizontal transverse bar of the pocket 7.

Une fois la poche 7 mise en place, la pince 6 est rendue solidaire du bord supérieur du tablier 2.Once the pocket 7 is in place, the clamp 6 is secured to the upper edge of the apron 2.

Puis l'extrémité 5a est fixée à l'arbre 1 par l'intermédiaire des encoches 5c coopérant avec les bords de la fente 1a. La fente 5d permet d'insérer l'extrémité 5a dans une fente 1a. Les encoches 5c assurent alors le maintien de l'extrémité 5a dans la fente 1a.Then the end 5a is fixed to the shaft 1 through the notches 5c cooperating with the edges of the slot 1a. The slot 5d makes it possible to insert the end 5a in a slot 1a. The notches 5c then maintain the end 5a in the slot 1a.

En fonctionnement, lors de l'enroulement du tablier 2 autour de l'arbre 1, les lames 3 forment des couches successives 3a, 3b (Fig. 2) autour de l'arbre 1. La première couche 3a, en contact direct avec l'arbre 1, comporte également le dispositif d'attache 4.In operation, during the winding of the apron 2 around the shaft 1, the blades 3 form successive layers 3a, 3b ( Fig. 2 ) around the shaft 1. The first layer 3a, in direct contact with the shaft 1, also comprises the attachment device 4.

La seconde couche 3b est enroulée au dessus de la première couche 3a et est donc en contact avec le dispositif d'attache 4. La pince 6 et la barrette flexible 5, enveloppées par la poche 7, ne sont pas en contact avec la seconde couche 3b et ne peuvent donc pas provoquer la formation de marques sur les lames formant la couche 3b.The second layer 3b is wound above the first layer 3a and is therefore in contact with the fastening device 4. The clip 6 and the flexible strip 5, wrapped by the pocket 7, are not in contact with the second layer 3b and therefore can not cause the formation of marks on the layers forming the layer 3b.

Une étude des zones du dispositif d'attache 4 provoquant des marques en l'absence de poche 7, permet de définir pour chaque type de volet roulant la forme de la poche 7. En particulier, dans certains cas les marques sont essentiellement provoquées par la pince 6 ce qui permet d'utiliser une poche 7 de taille réduite.A study of the zones of the attachment device 4 causing marks in the absence of pocket 7 makes it possible to define for each type of shutter the shape of the pocket 7. In particular, in some cases the marks are essentially caused by the clip 6 which allows to use a pocket 7 of reduced size.

Selon un mode de réalisation avantageux représenté Fig. 5, la poche 7 présente une section rectangulaire constante qui protège la barrette flexible 5 et une zone de la pince 6. Les parois opposées de la poche 7 sont réunies sur leurs bords, notamment par soudure W le long de la barrette 5. Les parois se prolongent par des languettes 7c dont les bords ne sont pas réunis. Les languettes 7c encadrent la pince 6 sur une largeur correspondant sensiblement à celle de la poche 7. Une telle poche peut être réalisée de façon économique et suffit à régler le problème existant à ce jour. La légère surépaisseur générée par les languettes 7c au niveau de la partie centrale de la pince 6 est suffisante pour éviter la formation de marques par les parties latérales de la pince 6.According to an advantageous embodiment represented Fig. 5 , the pocket 7 has a constant rectangular section which protects the flexible bar 5 and an area of the clamp 6. The opposite walls of the pocket 7 are joined at their edges, in particular by welding W along the bar 5. The walls are extend by tabs 7c whose edges are not joined. The tabs 7c frame the clip 6 to a substantially corresponding width to that of the pocket 7. Such a pocket can be achieved economically and is sufficient to solve the problem existing to date. The slight extra thickness generated by the tongues 7c at the central portion of the clamp 6 is sufficient to prevent marks from being formed by the lateral parts of the clamp 6.

Selon un mode de réalisation non représenté, la poche 7 est formée de deux feuilles sensiblement rectangulaires reliées entre elles le long de leurs bords supérieurs par une soudure interrompue en partie centrale pour permettre le passage de la barrette flexible 5.According to an embodiment not shown, the pocket 7 is formed of two substantially rectangular sheets interconnected along their upper edges by a weld interrupted in the central part to allow the passage of the flexible bar 5.
