Abstract

The apron is placed within a framework of the shutter, which is rolled up around a receiving drum for blockage in rotation. The fastener (4) is introduced between a hang point (5) of the drum (3) and an upper part (6) of the apron (1). The fastener has an articulation element rolled up around the drum when the apron is in high position, and a rigidifying element, which prevents involuntary or untimely raising, when the apron is in low position. The adjuster automatically adjusts the fastener dimension, when the apron is placed in a lower position. The adjustment is made at the level of the hang point by one-way blocker to block the fastener, when the drum is activated in rotation in an unwinding direction of the apron and to slip under the action of the weight of the apron when the drum is activated in rotation in a rolling direction of the apron. The blocking is done by a fixing rider to fix the drum, where the rider is cooperated with a transverse teeth (11) disposed longitudinally with the fastener. The fixing rider has a return wing, which is capable to be slipped/blocked according to the displacement direction of the fastener by the teeth. The transverse teeth has an orthogonal triangular section or in the form of hook. The fastener comprises a contiguous rigid blades which are parallelly disposed and connected by a flexible bonds. The blades and the bonds comprise a monolithic element, where the flexible bonds are realized by cavities constituting of weakenings of section, where the blades are fixed to a flexible element. A fixing agent fixes a monolithic element or a dismountable element to the body of the fastener, which inturn fixes to the upper part of the apron. The shutter further comprises a connection spring, which is distinct from the fastener and is cambered in a lower position to push downwards and is placed in position of the last upper blade of the apron. In the shutter, the upper end of the fastener comprises a stopper rod, which is cooperated directly/indirectly with the drum to the level of the hang point to allow raising the apron, when the drum is activated in the rolling direction.

Description

L'invention est relative à un volet roulant de protection pour ouverture, constitué essentiellement par un tablier, guidé, au moins dans un cadre placé dans ladite ouverture. Elle trouvera notamment son application dans le bâtiment lors de son utilisation de volet pour protéger les portes, les fenêtres ou autres.The invention relates to a protective shutter for opening, consisting essentially of an apron, guided, at least in a frame placed in said opening. It will particularly find its application in the building when using shutter to protect doors, windows or other.

Dans le domaine des volets roulants, le tablier est abaissé ou relevé par des dispositifs de commande. Néanmoins, l'espace libre entre l'extrémité supérieure des coulisses du tablier et le tambour constitue une zone d'enroulement où le tablier n'est plus guidé.In the field of shutters, the deck is lowered or raised by control devices. Nevertheless, the free space between the upper end of the apron slides and the drum constitutes a winding zone where the deck is no longer guided.

De ce fait, lorsque le tablier est en position baissée, on constate qu'il est possible de relever le tablier d'une certaine hauteur en agissant directement sur ce dernier, la partie supérieure du tablier ondulant dans la zone d'enroulement.Therefore, when the deck is in the lowered position, it is found that it is possible to raise the deck of a certain height by acting directly on the latter, the upper deck undulating in the winding area.

On connaît alors des attaches, appelées dispositifs de verrouillage, aptes à relier le tambour d'enroulement et la partie supérieure du tablier. Lorsque le tablier de volet roulant est en position basse, ces attaches se rigidifient pour empêcher tout relevage involontaire ou intempestif du tablier.Fasteners, known as locking devices, are then known which are capable of connecting the winding drum and the upper part of the apron. When the rolling shutter apron is in the low position, these fasteners are stiffened to prevent any inadvertent or inadvertent lifting of the deck.

On connaît par exemple du document FR-2.584.130 une attache constituée par des lames rigides, notamment plastiques, contigües et parallèles. Ces lames sont assujetties transversalement à au moins un élément souple élastique. Les lames rigides constituent alors des moyens d'arc-boutement qui permettent de rigidifier l'attache pour un certain rayon de courbure.For example, document is known FR-2584130 a fastener consisting of rigid blades, especially plastic, contiguous and parallel. These blades are transversely secured to at least one elastic flexible element. The rigid blades then constitute bracing means that stiffen the fastener for a certain radius of curvature.

Cette attache est généralement fixée entre la dernière lame supérieure du tablier de volet roulant et le tambour. Néanmoins, pour pouvoir fonctionner correctement, la dimension de l'attache doit être déterminée en fonction du déport vertical et horizontal séparant la dernière lame supérieure du tablier et le tambour d'enroulement.This fastener is generally fixed between the last upper blade of the rolling shutter apron and the drum. Nevertheless, to be able to function correctly, the size of the fastener must be determined according to the vertical and horizontal offset between the last upper blade of the deck and the winding drum.

Or, cette dimension est une variable qui dépend de la position finale de la lame supérieure du tablier lorsque ce dernier est abaissé. Toutefois, cette position est difficilement maîtrisable car elle dépend à la fois du pas des lames du tablier et de la hauteur de la fenêtre à protéger.However, this dimension is a variable that depends on the final position of the upper blade of the deck when the latter is lowered. However, this position is difficult to control because it depends both the pitch of the apron blades and the height of the window to be protected.

Par ailleurs, le déport peut également dépendre d'autres paramètres, tels que de la taille du coffre de volet roulant utilisé, du rayon du tambour de volet roulant, etc.In addition, the offset may also depend on other parameters, such as the size of the roller shutter box used, the radius of the shutter drum, etc.

Aussi, l'installation d'une telle attache à un volet roulant nécessite une phase de réglage au cours de laquelle le technicien va devoir fixer une longueur d'attache adaptée pour que cette dernière soit effective lorsque le tablier est en position basse.Also, the installation of such a fastener to a shutter requires an adjustment phase during which the technician will have to fix a fastener length adapted so that the latter is effective when the deck is in the low position.

Le but de la présente invention est de proposer un volet roulant de protection pour ouverture qui puisse pallier aux différents inconvénients cités ci-dessus et qui empêchent des manoeuvres non autorisées lorsque le volet roulant est en position fermée.The object of the present invention is to provide a protective rolling shutter for opening which can overcome the various disadvantages mentioned above and which prevent unauthorized maneuvers when the shutter is in the closed position.

Un autre but de l'invention est de proposer un volet roulant muni d'au moins une attache qui ne nécessite aucune phase de réglage lors de son installation.Another object of the invention is to provide a roller shutter provided with at least one fastener which requires no adjustment phase during installation.

Un autre but de l'invention est de proposer un volet roulant muni d'une attache standard qui puisse s'adapter aux différentes dimensions notamment de coffre de volet roulant.Another object of the invention is to provide a roller shutter with a standard fastener that can adapt to different dimensions including roller shutter box.

D'autres buts et avantages de la présente invention apparaîtront au cours de la description qui va suivre, qui n'est cependant donnée qu'à titre indicatif et qui n'a pas pour but de la limiter.Other objects and advantages of the present invention will become apparent from the description which follows, which is however given for information only and which is not intended to limit it.

L'invention concerne un volet roulant de protection pour ouverture, constitué essentiellement par un tablier 1 articulé notamment constitué de lames articulées entre elles.The invention relates to a protective roller shutter for opening, consisting essentially of an articulated apron 1 including blades articulated between them.

Le tablier est guidé, au moins en partie dans un cadre placé dans ladite ouverture, apte à s'enrouler autour d'un tambour récepteur 3 et apte à être bloqué en rotation.The apron is guided, at least in part in a frame placed in said opening, adapted to wind around a receiving drum 3 and adapted to be locked in rotation.

Ledit volet roulant présente au moins une attache 4 prévue entre un point d'accroche 5 du tambour 4 et la partie supérieure 6 du tablier. Ladite attache 4 présente, d'une part, des moyens d'articulation 7 pour s'enrouler autour dudit tambour 4 lorsque le tablier est en position haute et, d'autre part, des moyens, notamment d'arc-boutement, pour se rigidifier en un certain rayon de courbure lorsque le tablier 1 est en position basse, afin d'empêcher tout relevage involontaire ou intempestif de ce dernier.Said roller shutter has at least one fastener 4 provided between a hooking point 5 of the drum 4 and the upper part 6 of the apron. Said fastener 4 has, on the one hand, hinge means 7 for winding around said drum 4 when the apron is in the upper position and, on the other hand, means, in particular bracing, for rigidify in a certain radius of curvature when the apron 1 is in the low position, to prevent any inadvertent or inadvertent lifting of the latter.

II est à noter que l'attache 4 peut se rigidifier, le cas échéant, pour un rayon de courbure infini, constituant ainsi une droite, et ne pas être nécessairement une courbe concave ou convexe.It should be noted that the fastener 4 can be stiffened, if necessary, for an infinite radius of curvature, thus constituting a straight line, and not necessarily being a concave or convex curve.

Tel qu'illustré à la figure 1, le tambour récepteur 3 peut être notamment monté en rotation entre deux joues 13 aptes à fermer un coffre de volet roulant. Ces joues 13 peuvent être notamment fixées aux coulisses 14, encore appelées glissières, constituant ledit cadre placé dans l'ouverture à protéger, au moyen d'une patte, non illustrée, apte à coopérer dans un logement longitudinal des coulisses 14.As illustrated in Figure 1, the receiving drum 3 can be rotatably mounted between two cheeks 13 able to close a shutter box. These cheeks 13 may in particular be fixed to the slides 14, also called slides, constituting said frame placed in the opening to be protected, by means of a tab, not shown, adapted to cooperate in a longitudinal housing of the slides 14.

Un guide lame 15, encore appelé tulipe, peut être prévu pour guider les lames du tablier 1 au niveau de l'extrémité supérieure des coulisses 14.A blade guide 15, also called a tulip, may be provided for guiding the blades of the apron 1 at the upper end of the slides 14.

Selon l'invention, l'attache présente une longueur égale ou supérieure à la distance de montage séparant ledit point d'accroche 5 du tambour 3 et ladite partie supérieure 6 du tablier 1 lorsque ce dernier est en position basse.According to the invention, the fastener has an equal length or greater than the mounting distance separating said attachment point 5 of the drum 3 and said upper part 6 of the apron 1 when the latter is in the low position.

En outre, l'attache présente des moyens de réglage pour adapter automatiquement une dimension adéquate de ladite attache entre ledit point d'accroche 5 et ladite partie supérieure du tablier lorsque ce dernier est en position basse.In addition, the fastener has adjustment means for automatically adjusting an adequate dimension of said fastener between said attachment point 5 and said upper part of the deck when the latter is in the low position.

On entend par dimension adéquate, la longueur efficace de l'attache nécessaire pour que cette dernière se rigidifie et notamment s'arc-boute parfaitement lorsque le tablier est en position basse.By adequate dimension is meant the effective length of the fastener necessary for the latter to stiffen, and in particular to buckle perfectly when the apron is in the low position.

Selon un mode de réalisation, les moyens de réglage sont constitués, au niveau du point d'accroche 5, par des moyens 10, 11 de blocage unidirectionnel, aptes à bloquer l'attache pour unedite dimension adéquate de ladite attache lorsque le tambour est actionné en rotation dans le sens de déroulement du tablier et apte à glisser, sous l'action du poids du tablier 1, lorsque le tambour 4 est actionné en rotation dans le sens d'enroulement du tablier 1.According to one embodiment, the adjustment means are constituted, at the point of attachment 5, by unidirectional locking means 10, 11, able to block the fastener for a suitable dimension of said fastener when the drum is actuated. in rotation in the unwinding direction of the apron and able to slide, under the action of the weight of the deck 1, when the drum 4 is actuated in rotation in the winding direction of the deck 1.

Tels qu'illustrés aux figures, les moyens de blocage unidirectionnels sont constitués par un cavalier de fixation 10 assujetti audit tambour 3, apte à coopérer avec une denture transversale 11 disposée longitudinalement à l'attache 4.As illustrated in the figures, the unidirectional locking means are constituted by a fixing rider 10 secured to said drum 3, adapted to cooperate with a transverse toothing 11 arranged longitudinally to the clip 4.

Telle qu'illustrée aux figures 1 à 7 et 9, la denture transversale 1 est disposée sur le dos de l'attache 4, côté opposé au tambour 3.As illustrated in FIGS. 1 to 7 and 9, the transverse toothing 1 is disposed on the back of the fastener 4, opposite the drum 3.

Le cavalier de fixation 10 présente au moins une aile de retour 17 apte à glisser ou à se bloquer suivant le sens de déplacement de l'attache 4, avec la denture transversale 11.The attachment jumper 10 has at least one return wing 17 adapted to slide or lock in the direction of movement of the fastener 4, with the transverse toothing 11.

Selon un autre mode de réalisation illustré à la figure 8, la denture transversale 11 est disposée sur la surface concave de l'attache, côté tambour 3. Dans ce cas, l'aile de retour 17 contraint élastiquement la denture 11 à venir coopérer avec une dent 26, notamment conforme, du cavalier 10.According to another embodiment illustrated in FIG. 8, the transverse toothing 11 is disposed on the concave surface of the fastener, on the drum side 3. In this case, the return wing 17 elastically forces the toothing 11 to come into cooperation with a tooth 26, in particular according to the rider 10.

Tel qu'illustré aux figures 5 et 6 notamment le cavalier 10 est constitué par deux éléments de fixation 23. Chaque élément de fixation 23 peut présenter une partie inférieure 18 apte à coulisser dans un rail en Ω du tambour 3.As illustrated in FIGS. 5 and 6, in particular jumper 10 is constituted by two fastening elements 23. Each fastening element 23 may have a lower portion 18 slidable in a Ω rail of the drum 3.

Les deux éléments de fixation 23 sont insérés dans le rail 19 à chacune des extrémités du tambour et sont translatés pour venir en prise avec l'attache 4. Les éléments de fixation 23 présentent chacun une partie supérieure en L couché constituant ladite aile de retour 17 apte à venir coopérer avec le dos de l'attache 4.The two fastening elements 23 are inserted into the rail 19 at each end of the drum and are translated to engage with the fastener 4. The fasteners 23 each have a top L-shaped coated constituting said wing return 17 able to cooperate with the back of the fastener 4.

Le tambour 3 peut être obtenu à partir d'un feuillard métallique après plusieurs opérations de pliage successifs permettant notamment de réaliser ledit rail en Ω 19.The drum 3 can be obtained from a metal strip after several successive folding operations making it possible in particular to make said rail in Ω 19.

Lorsque le tambour 3 ne présente pas de conformation en queue d'aronde, les deux éléments de fixation 23 peuvent être fixés aux extrémités du tambour 3 au moyen de bague 25. Tel qu'illustrés à la figure 9, unedite bague 25 présente une protubérance 29 à fonction de clavette, apte à coopérer avec une rainure longitudinale 27 au tambour 3, afin d'assujettir en rotation ladite bague 25 au tambour 3.When the drum 3 does not have a dovetail conformation, the two fastening elements 23 can be fixed to the ends of the drum 3 by means of a ring 25. As illustrated in FIG. 9, a said ring 25 has a protuberance 29 with key function, adapted to cooperate with a longitudinal groove 27 to the drum 3, in order to rotate said ring 25 to the drum 3.

Chaque bague 25 présente également une languette 28 de longueur sensiblement égale à la longueur du tambour et présentant à son extrémité un clip de fixation 30 apte à coopérer avec une partie complémentaire 31 sur l'autre bague.Each ring 25 also has a tongue 28 of length substantially equal to the length of the drum and having at its end a fastening clip 30 adapted to cooperate with a complementary portion 31 on the other ring.

Telles qu'illustrées aux figures 2 et 3, les dents 12 constituant la denture transversale 11 présentent une section triangulaire orthogonale ou encore une section en forme de rochet. Aussi, tel qu'illustré à la figure 2, lorsque le tablier 1 est en position basse, le tambour 3 continue sa rotation un bref instant jusqu'à ce que le cavalier 10 vienne se bloquer, tel qu'illustré à la figure 3 sur la dent 12 le plus favorable au blocage.As illustrated in Figures 2 and 3, the teeth 12 constituting the transverse toothing 11 have an orthogonal triangular section or a ratchet-shaped section. Also, as illustrated in Figure 2, when the apron 1 is in the low position, the drum 3 continues its rotation for a short time until the rider 10 comes to lock, as shown in Figure 3 on the tooth 12 most favorable to the blockage.

L'extrémité supérieure de l'attache 4 présente en outre des moyens de butée 8 aptes à coopérer directement ou indirectement avec le tambour 3, au niveau du point d'accroche 5 pour permettre le relevage du tablier lorsque le tambour 3 est actionné dans le sens d'enroulement.The upper end of the fastener 4 further has stop means 8 adapted to cooperate directly or indirectly with the drum 3, at the point of attachment 5 to allow the lifting of the deck when the drum 3 is actuated in the winding direction.

Tels qu'illustrés à la figure 1 ou aux figures 5 et 6, les moyens de butée sont constitués par des saillies, notamment latérales à l'attache 4, aptes à coopérer le cavalier 10, notamment au niveau d'unedite aile 17.As illustrated in FIG. 1 or in FIGS. 5 and 6, the abutment means are constituted by protrusions, in particular lateral to the fastener 4, able to cooperate with the rider 10, particularly at the level of one of said wings 17.

Aussi, lorsque le tablier 1 est en position basse et que le tambour 3 est actionné en rotation dans le sens d'enroulement, l'attache 4 glisse dans le cavalier 10 jusqu'à ce que ce dernier entre en contact avec les saillies des moyens de butée 8. Dès lors, le tablier 1 est entraîné en montée par la rotation du tambour 4. L'attache ainsi que les lames du tablier s'enroulent alors autour du tambour 3 tel qu'illustré à la figure 4.Also, when the apron 1 is in the low position and the drum 3 is actuated in rotation in the winding direction, the fastener 4 slides in the jumper 10 until the latter comes into contact with the projections of the means 8. Therefore, the deck 1 is driven uphill by the rotation of the drum 4. The fastener and the apron blades are then wound around the drum 3 as shown in Figure 4.

Telle qu'illustrée aux figures 1 à 7 et 9, l'attache est constituée par une pluralité de lames rigides 41 contigües et disposées parallèles, liées entre elles par des moyens de liaisons 7' souples. Ces lames rigides constituent des moyens d'arc-boutement qui permettent à l'attache de se rigidifier pour un certain rayon de courbure lorsque le tablier 1 est en position basse.As illustrated in Figures 1 to 7 and 9, the fastener is constituted by a plurality of rigid blades 41 contiguous and arranged parallel, interconnected by flexible connecting means 7 '. These rigid blades are bracing means which allow the fastener to become rigid for a certain radius of curvature when the deck 1 is in the low position.

Selon un premier mode de réalisation illustré aux figures, lesdites lames rigides 41 ainsi que les moyens de liaison 7' constituent un élément monolithique, les moyens de liaison 7' étant réalisés dans la masse au moyen d'évidements constituant des affaiblissements de section. Dans ce mode de réalisation, l'attache est réalisée en matière plastique notamment par les procédés de moulage par injection.According to a first embodiment illustrated in the figures, said rigid blades 41 as well as the connecting means 7 'constitute a monolithic element, the connecting means 7' being made in the mass by means of recesses constituting section losses. In this embodiment, the fastener is made of plastic material in particular by injection molding processes.

Selon un autre mode de réalisation, les lames rigides 41 contigües sont assujetties à au moins un élément souple rapporté.According to another embodiment, the rigid blades 41 contiguous are subject to at least one reported flexible element.

Dans ce mode de réalisation, les lames rigides 41, notamment en matière plastique, sont assujetties transversalement à au moins une lame élastique. Les lames rigides 41 peuvent être fixées à ladite au moins une lame élastique par tout moyen et notamment au moyen de rivets.In this embodiment, the rigid blades 41, in particular plastic, are transversely secured to at least one elastic blade. The rigid blades 41 may be attached to the at least one elastic blade by any means and in particular by means of rivets.

Telle qu'illustrée aux figures 2 et 3, selon un premier mode de réalisation, chaque lame rigide 41 forme une dent 12 de la denture transversale 11.As illustrated in FIGS. 2 and 3, according to a first embodiment, each rigid blade 41 forms a tooth 12 of the transverse toothing 11.

Selon un second mode de réalisation illustré aux figures 5 et 6, chaque lame rigide 41 constitue plusieurs dents 12.According to a second embodiment illustrated in FIGS. 5 and 6, each rigid blade 41 constitutes several teeth 12.

Par ailleurs, toujours aux figures 5 et 6, les lames 41 de l'attache 4 présentent, au niveau d'une zone dorsale ne coopérant pas avec l'aile de retour 17 des éléments de fixation 23 constituant le cavalier 10, une portion centrale 20 sans denture. La position centrale 20 permet de protéger les premières lames du tablier qui s'enroulent du marquage des dents 12. Cette portion centrale 20 permet également d'augmenter la surface de contact entre chaque lame 41 voisine, et ainsi permet de favoriser le phénomène d'arc-boutement.Furthermore, still in FIGS. 5 and 6, the blades 41 of the fastener 4 have, at a dorsal zone that does not cooperate with the return wing 17, fastening elements 23 constituting the rider 10, a central portion 20 without teeth. The central position 20 makes it possible to protect the first blades of the apron which are wound by the marking of the teeth 12. This central portion 20 also makes it possible to increase the contact area between each adjacent blade 41, and thus makes it possible to promote the phenomenon of buttressing.

La figure 7 illustre un troisième mode de réalisation d'une attache conforme à l'invention, dans lequel, la denture transversale 11 est constituée par de simples saillies 12. Le cavalier 10 présente alors au niveau de l'aile de retour 17 un pan oblique afin de bloquer ou d'autoriser le glissement de l'attache 4.FIG. 7 illustrates a third embodiment of a fastener according to the invention, in which the transverse toothing 11 consists of simple protrusions 12. The rider 10 then presents at the level of the return wing 17 a portion oblique in order to block or allow the slipping of the fastener 4.

L'extrémité inférieure de l'attache 4 présente des moyens de fixation 9 aptes à coopérer, notamment par crochet, avec des moyens complémentaires de la partie supérieure du tablier 1.The lower end of the fastener 4 has fastening means 9 able to cooperate, in particular by hook, with means complementary to the upper part of the deck 1.

Lesdits moyens de fixation 9 de l'attache 4 à la partie supérieure du tablier 1 constituent avec le corps de ladite attache un élément monolithique, ou encore constituent un élément distinct prévu pour être démontable.Said fixing means 9 of the fastener 4 to the upper part of the deck 1 together with the body of said fastener a monolithic element, or constitute a separate element provided to be removable.

Aussi, la dernière lame inférieure 9 de l'attache 4 constitue une mâchoire de fixation apte à coopérer avec un profil de forme en crochet de la lame supérieure du tablier 1.Also, the last lower blade 9 of the fastener 4 constitutes a fastening jaw capable of cooperating with a hook-shaped profile of the upper blade of the apron 1.

Selon un mode de réalisation, l'attache 4 conforme à l'invention peut être complétée par une liaison ressort, distincte, prévue entre le tambour 3 et la lame supérieure du tablier. Cette liaison ressort a pour fonction de pousser vers le bas et mettre la dernière lame supérieure du tablier en bonne position, notamment dans les coulisses du tablier.According to one embodiment, the fastener 4 according to the invention may be supplemented by a separate spring connection provided between the drum 3 and the upper blade of the apron. This spring link has the function of pushing down and put the last upper blade of the deck in good position, especially in the wings of the deck.

Cette liaison ressort peut être de même longueur que l'attache 4 conforme à l'invention et se cambrer en position basse. Elle trouvera un intérêt particulier en cas de tablier léger pour lequel les dernières lames supérieures peuvent s'arc-bouter dans les coulisses.This spring connection may be of the same length as the fastener 4 according to the invention and arch in the low position. She will find a special interest in the case of a light apron for which the last upper blades can be arched behind the scenes.

Naturellement, d'autres modes de mise en oeuvre à la portée de l'homme de l'art, auraient pu être envisagés sans pour autant sortir du cadre de l'invention.Naturally, other modes of implementation within the reach of those skilled in the art could have been envisaged without departing from the scope of the invention.
