Abstract

The shutter has a self-locking device to lock an apron in a deployed position, where the apron is deployed to extend in the lateral slides from a winding tube (6). Connection units connect a slate (3) of the apron to the tube. The units cause a tilting of the slate, after complete unwinding of the apron, within the slides, to bring hooking units equipping the apron to cooperate with hooking units (10) arranged in the slides.

Description

L'invention concerne un volet roulant comportant un tablier constitué d'une juxtaposition de lames au moins articulées entre elles et conçues aptes à se déployer, pour s'étendre dans des coulisses latérales de guidage, depuis un tube d'enroulement grâce à un mécanisme d'entraînement adapté, ledit volet roulant comportant encore un dispositif d'autoblocage dudit tablier en position déployée.The invention relates to a shutter comprising an apron consisting of a juxtaposition of blades at least hinged together and designed to deploy, to extend in lateral guide channels, from a winding tube through a mechanism adapted driving, said shutter further comprising a self-locking device of said apron in the deployed position.

La présente invention concerne plus particulièrement le domaine des volets roulants.The present invention relates more particularly to the field of roller shutters.

A ce propos, un tel volet roulant comporte, de manière usuelle, un tablier constitué d'une juxtaposition de lames au moins articulées entre elles de manière à autoriser son repliement sur un tube d'enroulement actionné en rotation par l'intermédiaire d'un mécanisme d'entraînement manuel ou motorisé adapté.In this connection, such a shutter comprises, in the usual manner, an apron consisting of a juxtaposition of blades at least articulated to each other so as to allow its folding on a winding tube actuated in rotation by means of a suitable manual or motorized drive mechanism.

A noter que ce tube d'enroulement y compris ledit mécanisme d'entraînement prend position dans un caisson sous lequel s'étendent, latéralement, des coulisses dans lesquelles viennent se déplacer des extrémités latérales desdites lames en cours de déploiement du tablier.Note that this winding tube including said drive mechanism takes position in a box in which laterally extend slides in which are moved side ends of said blades during deployment of the deck.

Un tel volet roulant comporte encore, de manière usuelle, un dispositif d'autoblocage du tablier en position déployée ayant pour fonction d'empêcher que celui-ci puisse remonter dans le caisson sous l'influence d'une poussée qui lui serait appliquée directement, par exemple, lors d'une tentative d'effraction.Such a shutter also comprises, in the usual manner, a self-locking device of the deck in the deployed position whose function is to prevent it from being able to go up in the caisson under the influence of a thrust applied to it directly, for example, during an attempted break-in.

Ainsi, selon un exemple de réalisation, de tels dispositifs d'autoblocage sont constitués d'un, deux ou davantage de maillons, reliant la première lame du tablier au tube d'enroulement et qui ont la faculté, d'une part, de venir se replier autour de ce dernier pour ne pas gêner l'enroulement dudit tablier à l'intérieur du caisson et, d'autre part, de s'arc-bouter entre cet arbre d'enroulement et ladite première lame du tablier lorsque celui-ci est en position totalement déployée.Thus, according to an exemplary embodiment, such self-locking devices consist of one, two or more links connecting the first blade of the apron to the winding tube and which have the ability, on the one hand, to come himself fold around the latter so as not to hinder the winding of said apron inside the box and, on the other hand, to bend between this winding shaft and said first deck blade when it is in fully deployed position.

L'on comprend bien que ce type de dispositif d'autoblocage n'est efficace que lorsqu'il se trouve dans une position bien déterminée qu'il convient de maîtriser parfaitement. Tout particulièrement, il y a lieu de tenir compte, dans ce but, de la distance séparant la première lame du tablier de l'arbre d'enroulement, sachant que cette distance est variable en fonction de la section que présente le tablier enroulé et, donc, de la taille du volet roulant. En quelque sorte, pour obtenir un fonctionnement optimal, la taille et le nombre des maillons constituant le dispositif d'autoblocage doivent être strictement déterminés par rapport à la distance précitée.It is understood that this type of self-locking device is effective only when it is in a specific position that should be mastered perfectly. In particular, it is necessary to take into account, for this purpose, the distance separating the first blade of the deck of the winding shaft, knowing that this distance is variable depending on the section of the rolled deck and, therefore, the size of the shutter. In a way, to obtain optimal operation, the size and the number of links constituting the self-locking device must be strictly determined with respect to the aforementioned distance.

Par ailleurs, les maillons correspondant à de tels dispositifs d'autoblocage, sont, très souvent, à l'origine d'une section plus importante du tablier de volet roulant enroulé autour du tube d'enroulement.Furthermore, the links corresponding to such self-locking devices, are very often at the origin of a larger section of the rolling shutter apron wound around the winding tube.

Il est encore connu, au travers du document DE-U-94 03 638 , de relier la première lame du tablier à l'arbre d'enroulement au moyen de lames élastiques qui, en phase finale de déploiement du tablier, ont tendance à se déployer naturellement et de ce fait à repousser cette première lame en direction de la paroi externe du caisson. Un rail d'accrochage surmontant cette première lame du tablier vient alors coopérer au travers de ses extrémités débordant de part et d'autre de ladite lame avec une échelle équipant, latéralement, cette paroi du caisson.He is still known, through the document DE-U-94 03 638 connecting the first leaf of the apron to the winding shaft by means of elastic blades which, in the final phase of deployment of the deck, have a tendency to unfold naturally and thus to push the first blade towards the wall external of the box. A hooking rail surmounting this first deck blade then cooperates through its ends protruding on either side of said blade with a ladder equipping, laterally, this wall of the box.

Ainsi, quelle que soit la position adoptée une fois le tablier du volet roulant totalement déployé et, donc, quelles que soient les contraintes rencontrées conformément aux explications ci-dessus, en tentant de repousser ce tablier dans son caisson, il en résulte, sous l'impulsion desdites lames élastiques, la coopération du rail d'accrochage avec l'une des dentures de ladite échelle.Thus, irrespective of the position adopted once the roll shutter apron has been fully deployed and, therefore, whatever the constraints encountered in accordance with the explanations above, while attempting to push this apron into its box, it results, under the impulse of said elastic blades, the cooperation of the latching rail with one of the teeth of said scale.

Le problème que pose une telle solution réside, là encore, dans l'usage des lames élastiques reliant la première lame du tablier au tube d'enroulement.The problem posed by such a solution resides, again, in the use of the elastic blades connecting the first blade of the deck to the winding tube.

De telles lames qui sont définies aptes à exercer une poussée sur le tablier pour activer le dispositif de blocage peuvent, en phase initiale du repliement du tablier, gêner l'enroulement normal de ses premières spires autour du tube d'enroulement, de sorte que la section de ce tablier enroulé peut s'avérer, dans certains cas, plus importante que nécessaire. En tenant compte de ce risque, il est indispensable de dimensionner le caisson du volet roulant destiné à abriter ce tablier en position enroulée.Such blades which are defined capable of exerting a thrust on the apron to activate the locking device may, in the initial phase of the folding of the deck, interfere with the normal winding of its first turns around the winding tube, so that the section of this wrapped apron may be, in some cases, larger than necessary. Taking into account this risk, it is essential to size the casing of the roller shutter intended to house this deck in wound position.

Par ailleurs, l'efficacité du dispositif de blocage est dépendante de la fatigue des lames élastiques au cours du temps. Ainsi, si elles sont choisies de faible raideur pour limiter les risques à l'enroulement précité, à la longue cette raideur peut s'avérer insuffisante pour repousser le tablier avec son profil d'accrochage en coopération avec les éléments d'accostage dont est pourvue la paroi avant dudit caisson.Moreover, the effectiveness of the locking device is dependent on the fatigue of the elastic blades over time. Thus, if they are chosen of low stiffness to limit the risks to the aforementioned winding, in the long run this stiffness may be insufficient to push back the apron with its attachment profile in cooperation with the docking elements which is provided the front wall of said box.

En fin de compte, la présente invention tente de remédier aux problèmes précités au travers d'une solution se servant de la cinématique du fonctionnement d'un volet roulant pour assurer tout naturellement le blocage du tablier en position totalement déployée.In the end, the present invention attempts to remedy the aforementioned problems through a solution using the kinematic operation of a roller shutter to ensure naturally the blocking of the deck in fully deployed position.

Ainsi, l'invention concerne un volet roulant comportant un tablier constitué d'une juxtaposition de lames au moins articulées entre elles et conçues aptes à se déployer, pour s'étendre dans des coulisses latérales de guidage, depuis un tube d'enroulement grâce à un mécanisme d'entraînement adapté, ledit volet roulant comportant encore un dispositif d'autoblocage dudit tablier en position déployée, caractérisé par le fait qu'il comporte des moyens de liaison reliant la première lame du tablier au tube d'enroulement conçus aptes, après déroulement complet dudit tablier, à provoquer le basculement d'au moins ladite première lame dudit tablier à l'intérieur de ladite coulisse latérale de guidage, pour amener des moyens d'accrochage équipant ledit tablier à coopérer avec des moyens d'accostage ménagés dans ladite coulisse latérale.Thus, the invention relates to a roller shutter comprising an apron consisting of a juxtaposition of blades at least hinged together and designed to deploy, to extend in lateral guide slides, since a winding tube through a suitable drive mechanism, said shutter further comprising a self-locking device of said apron in the deployed position, characterized in that it comprises connecting means connecting the first plate of the deck to the tube d winding adapted adapted, after complete unwinding of said apron, to cause the tilting of at least said first blade of said apron within said lateral guide slide, to bring hooking means equipping said apron to cooperate with means of docking formed in said lateral slide.

Lesdits moyens de liaison sont conçus aptes, lors de la commande en rotation d'enroulement de ce dernier, à exercer sur ledit tablier une traction selon une première résultante, dans le plan du tablier, et, lors de la commande en rotation de déroulement du tube d'enroulement, après déploiement total dudit tablier et sous l'impulsion d'une rotation complémentaire, à exercer sur ce tablier une traction selon une seconde résultante à composante perpendiculaire au plan de ce tablier dans une seconde direction opposée à la première, cette seconde résultante étant divergente par rapport à la première pour repousser, en direction de moyens d'accostage, des moyens d'accrochage associés audit tablier, du côté correspondant à ladite seconde direction, lesdits moyens d'accostage et les moyens d'accrochage constituant, substantiellement ledit dispositif de blocage.Said connecting means are conceived suitable, during the control of the winding rotation of the latter, to exert on said apron a traction according to a first resultant, in the plane of the deck, and, during the control in rotation of unwinding of the winding tube, after total deployment of said deck and under the impulse of a complementary rotation, to exert on this deck a traction according to a resultant second component perpendicular to the plane of the deck in a second direction opposite to the first, this second resultant being divergent with respect to the first to repel, in the direction of docking means, the attachment means associated with said apron, the side corresponding to said second direction, said docking means and the fastening means constituting, substantially said blocking device.

Selon un même concept inventif, lesdits moyens de liaison sont conçus aptes, lors de la commande en rotation d'enroulement de ce dernier, à exercer sur ledit tablier une traction selon une première résultante à composante perpendiculaire au plan dudit tablier dans une première direction et, lors de la commande en rotation de déroulement du tube d'enroulement, après déploiement total dudit tablier et sous l'impulsion d'une rotation complémentaire, à exercer sur ledit tablier une traction selon une seconde résultante à composante perpendiculaire au plan dudit tablier, dans une seconde direction, opposée à la première, cette seconde résultante étant divergente par rapport à la première pour repousser, en direction de moyens d'accostage, des moyens d'accrochage associés audit tablier, du côté correspondant à ladite seconde direction, lesdits moyens d'accostage et lesdits moyens d'accrochage constituant, substantiellement ledit dispositif d'autoblocage.According to one and the same inventive concept, said connecting means are adapted, during the control of the winding rotation of the latter, to exert on said apron a traction according to a first resultant component perpendicular to the plane of said apron in a first direction and during the rotational control of unwinding of the winding tube, after total deployment of said apron and under the impulse of a complementary rotation, to exert on said apron a traction according to a resultant second component perpendicular to the plane of said apron, in a second direction, opposite the first, this second result being divergent with respect to the first to repel, in the direction of docking means, the attachment means associated with said apron, the side corresponding to said second direction, said docking means and said means of docking; fastening component, substantially said self-locking device.

Ainsi le tablier bascule, dans l'espace délimité par les coulisses latérales, d'une paroi vers la paroi opposée.Thus the deck tilts, in the space delimited by the lateral slides, a wall towards the opposite wall.

Selon un mode de réalisation avantageux, les moyens d'accostage sont ménagés dans les coulisses latérales de guidage.According to an advantageous embodiment, the docking means are formed in the lateral guide slides.

La présente invention sera mieux comprise à lecture de la description qui va suivre se rapportant à un exemple de réalisation illustré dans les dessins joints en annexe.

  • la figure 1 est une représentation schématisée partielle et en coupe d'un volet roulant au cours d'un déploiement ;
  • la figure 2 est une vue schématisée similaire à la figure 1 illustrant le volet roulant après déploiement total du tablier ;
  • la figure 3 est une vue similaire aux deux figures précédentes, représentent, le dispositif de blocage selon l'invention activé sous l'effet d'une rotation complémentaire de déroulement du tube d'enroulement après déploiement total du tablier.
The present invention will be better understood on reading the following description relating to an exemplary embodiment illustrated in the accompanying drawings.
  • Figure 1 is a partial schematic representation in section of a roller shutter during a deployment;
  • Figure 2 is a schematic view similar to Figure 1 illustrating the shutter after total deployment of the deck;
  • Figure 3 is a view similar to the two previous figures, show, the locking device according to the invention activated under the effect of a complementary rotation unwinding of the winding tube after total deployment of the deck.

Tel que représenté dans les figures des dessins ci-joints, la présente invention concerne le domaine des volets roulants.As shown in the figures of the accompanying drawings, the present invention relates to the field of shutters.

Un tel volet roulant 1 comporte un tablier 2 constitué d'une juxtaposition de lames 3, 4 au moins articulées entre elles et conçues aptes à se déployer pour s'étendre dans des coulisses latérales de guidage 5, à partir d'un tube d'enroulement 6.Such a shutter 1 comprises an apron 2 consisting of a juxtaposition of blades 3, 4 at least hinged together and designed to deploy to extend in lateral guide slides 5, from a tube of winding 6.

A ce propos, celui-ci est habituellement monté en rotation dans un caisson 7 surmontant les coulisses latérales 5 et prenant position en partie supérieure d'une ouverture dans une construction correspondant à une porte, fenêtre ou similaire.In this respect, it is usually mounted in rotation in a box 7 surmounting the lateral slides 5 and taking up position in the upper part of an opening in a construction corresponding to a door, window or the like.

Il est usuel, également, qu'un tel volet roulant 1 soit pourvu d'un dispositif 8 d'autoblocage dudit tablier 2 en position déployée. Tout particulièrement, un tel dispositif d'autoblocage a pour fonction d'empêcher, une fois le volet roulant 1 refermé, que l'on puisse, dans le cadre d'une tentative d'effraction, repousser le tablier 2 dans le caisson 7.It is also customary for such a shutter 1 to be provided with a device 8 for self-locking said apron 2 in the deployed position. In particular, such a self-locking device has the function of preventing, once the shutter 1 closed, that it is possible, in the context of an attempted break-in, to push the apron 2 into the box 7.

Pour faciliter la compréhension de la description qui va suivre, il a été identifié sur les dessins ci-joints, le côté externe du volet roulant par la référence E et le côté interne par la référence I, étant toutefois précisé que ce qui est considéré comme étant un dispositif du côté interne est susceptible de se situer du côté externe et vice-versa. En somme, la présente invention n'est nullement limitée à une telle disposition correspondant à la description ci-dessous.To facilitate the understanding of the description which follows, it has been identified in the accompanying drawings, the outer side of the shutter by the reference E and the inner side by the reference I, however, it is specified that what is considered as being a device on the inner side is likely to be on the outer side and vice versa. In short, the present invention is not limited to such an arrangement corresponding to the description below.

A ce propos, l'on remarquera que le volet roulant 1 comporte des moyens de liaison 9 venant relier la première lame 3 du tablier 2 au tube d'enroulement 6. Ces moyens de liaison 9 sont tout particulièrement conçus pour, lorsque l'on commande en rotation ledit tube d'enroulement 6 dans le sens d'enroulement du tablier 2, sens identifié par la flèche F1, il est exercé sur ce tablier 2 une traction selon une première résultante R1, selon le cas, dans le plan P du tablier 2 ou à composante perpendiculaire C1, dans une première direction D1, correspondant, sur les dessins, à celle allant vers le côté interne I.In this regard, it will be noted that the shutter 1 comprises connecting means 9 connecting the first blade 3 of the deck 2 to the winding tube 6. These connecting means 9 are particularly designed for, when one controlling in rotation said winding tube 6 in the winding direction of the deck 2, direction identified by the arrow F1, it is exerted on the deck 2 a traction according to a first resultant R1, as the case may be, in the plane P of the apron 2 or perpendicular component C1, in a first direction D1, corresponding, in the drawings, to that going to the inner side I.

Ces moyens de liaison 9 sont encore conçus, lors de la commande en rotation du tube d'enroulement 6 dans le sens du déroulement F2 du tablier 2, après déploiement total de ce dernier et sous l'impulsion d'une rotation complémentaire, que l'on a repérée Rc dans la figure 3, à exercer sur ce tablier 2 une traction selon une seconde résultante R2 qui, respectivement à la première résultante R1, est à composante perpendiculaire C2 dans une seconde direction D2, opposée à la première D1.These connection means 9 are furthermore designed, when the winding tube 6 is rotated in the direction of the unfolding F2 of the deck 2, after total deployment of the latter and under the pulse of a complementary rotation, which has been marked Rc in FIG. 3, to exert on this deck 2 a traction according to a second resultant R2 which, respectively to the first resultant R1, has a perpendicular component C2 in a second direction D2, opposite the first D1.

Il y a donc deux cas de figure possibles :

  • la première résultante R1 est dans le plan P du tablier 2, et la deuxième résultante R2 possède une composante perpendiculaire au plan P dans une direction D2,
  • la première résultante R1 possède une composante perpendiculaire au plan P du tablier 2 dans une direction D1, et la deuxième résultante R2 possède une composante perpendiculaire au plan P dans une direction D2, opposée à ladite direction D1.
There are two possible scenarios:
  • the first resultant R1 is in the plane P of the deck 2, and the second resultant R2 has a component perpendicular to the plane P in a direction D2,
  • the first resultant R1 has a component perpendicular to the plane P of the deck 2 in a direction D1 , and the second resultant R2 has a component perpendicular to the plane P in a direction D2, opposite to said direction D1.

En fait, cette seconde résultante R2 est nécessairement divergente par rapport à la première R1 et est définie pour repousser, en direction de moyens d'accostage 10, des moyens d'accrochage 11 associés audit tablier 2, ceci pour assurer un blocage de celui-ci en position déployée. En somme, ces moyens d'accrochage 10 et les moyens d'accrochage 11 définissent, substantiellement, le dispositif d'autoblocage 8 de ce volet roulant 1.In fact, this second resultant R2 is necessarily divergent with respect to the first R1 and is defined to push, in the direction of docking means 10, hooking means 11 associated with said apron 2, this to ensure a locking of the latter. in the deployed position. In sum, these attachment means 10 and the attachment means 11 define, substantially, the self-locking device 8 of the shutter 1.

Selon l'invention, lesdits moyens d'accostage 10 sont ménagés dans l'une au moins des coulisses latérales 5.According to the invention, said docking means 10 are formed in at least one of the lateral wings 5.

Celles-ci sont en forme de profilé de section en U ouvert latéralement et comportant deux parois parallèles 12, 13. Ainsi, les moyens d'accostage 10 se présentent plus particulièrement sous forme d'une échelle 14 équipant, intérieurement à ladite coulisse latérale 5, la paroi 12 située du côté opposé à la première direction D1, c'est-à-dire dans la seconde direction D2.These are in the form of a section section open laterally and having two parallel walls 12, 13. Thus, the docking means 10 are more particularly in the form of a scale 14 fitted internally to said lateral slide 5 , the wall 12 located on the opposite side to the first direction D1, that is to say in the second direction D2.

Cette échelle 14 est plus particulièrement ménagée dans la partie d'extrémité 15 de la coulisse latérale 5 aboutant au caisson 7.This ladder 14 is more particularly formed in the end portion 15 of the lateral slide 5 abutting the box 7.

Quant aux moyens d'accrochage 11, sous forme de crochets 16, ils équipent le tablier 2, à son extrémité 17 correspondant à la première lame 3, plus particulièrement en bordure latérale venant se déplacer dans les coulisses latérales 5, qui plus est du côté 18 en regard des moyens d'accostage 10.As for the hooking means 11, in the form of hooks 16, they equip the deck 2, at its end 17 corresponding to the first blade 3, more particularly at the side edge moving in the lateral slides 5, which is on the side 18 next to the docking means 10.

Les éléments en forme de crochets 16, définis pour former redan en coopération avec l'échelle 14, peuvent directement équiper la première lame 3 dudit tablier 2 ou un profilé de jonction 19 au travers duquel les moyens de liaison 9 coopèrent avec ladite première lame 3. En fait, ces éléments en forme de crochet 16 peuvent encore être ménagés au niveau desdits moyens de liaison 9.The hook-shaped elements 16, defined to form redan in cooperation with the scale 14, can directly equip the first blade 3 of said apron 2 or a joining profile 19 through which the connecting means 9 cooperate with said first blade 3 In fact, these hook-shaped elements 16 may be further provided at said connecting means 9.

De manière préférentielle, ceux-ci se présentent sous forme d'attaches souples 20 dont une extrémité est rendue solidaire du tube d'enroulement 6 et dont l'extrémité opposée vient coopérer directement ou par l'intermédiaire du profilé de jonction 19 précité avec la première lame 3 du tablier 2.Preferably, these are in the form of flexible fasteners 20, one end of which is secured to the winding tube 6 and whose opposite end cooperates directly or through the aforementioned connecting section 19 with the first blade 3 of the apron 2.

Selon un mode de réalisation préférentiel de l'invention, le plan P dans lequel vient se déployer le tablier 2 croise la section du tube d'enroulement 6. Autrement dit, le tube d'enroulement 6 ne se situe pas exclusivement, d'un côté ou de l'autre de ce plan P du tablier 2 de telle sorte qu'en phase finale de déploiement de ce tablier 2 et sous l'effet de la rotation complémentaire RC du tube d'enroulement 6 dans le sens du déroulement, le point d'attache 21 des moyens de liaison 9 sur le tube d'enroulement 6 passe d'un côté I du côté opposé E audit plan P.According to a preferred embodiment of the invention, the plane P in which the apron 2 deploys crosses the section of the winding tube 6. In other words, the winding tube 6 is not located exclusively, a either side of this plane P of the deck 2 so that in the final phase of deployment of the deck 2 and under the effect of the complementary rotation RC of the winding tube 6 in the direction of unwinding, the attachment point 21 of the connecting means 9 on the winding tube 6 passes from one side I of the opposite side E to said plane P.

Il convient de remarquer que ce qui est entendu, ci-dessus, des moyens d'accostage peuvent constituer des moyens d'accrochage et vice versa.It should be noted that what is understood, above, means of docking may constitute hooking means and vice versa.

Tel qu'il ressort de la description qui précède, la solution selon l'invention évite l'emploi de dispositifs d'autoblocage plus complexes tels que connus dans l'état de la technique.As can be seen from the foregoing description, the solution according to the invention avoids the use of more complex self-locking devices as known in the state of the art.

En particulier, les moyens de liaison reliant le tablier 2 au tube d'enroulement 6 peuvent être définis par de simples sangles. Si de telles sangles posaient, jusqu'alors, le risque d'un enroulement dans un sens incorrect du tablier 2 autour du tube d'enroulement 6, ce risque n'est pas encouru au travers de la solution selon l'invention.In particular, the connecting means connecting the apron 2 to the winding tube 6 can be defined by simple straps. If such straps posed, until then, the risk of a winding in an incorrect direction of the apron 2 around the winding tube 6, this risk is not incurred through the solution according to the invention.

En somme, tel qu'il ressort de ce qui précède, la présente invention ne répond pas seulement à un problème d'autoblocage d'un tablier en position déployée, mais, en outre, à celui de la complexité des systèmes actuellement existants.In sum, as can be seen from the foregoing, the present invention not only addresses a self-locking problem of an apron in the deployed position, but, in addition, to that of the complexity of the currently existing systems.
