Abstract

The lock (1) for the roller blind comprises a set of at least two links (2,3,4) articulated by a system of hinges. The hinge system cannot be dismantled in the normal operating zone and causes buttressing of the links when the shutter is completely unfurled. The links are also provided with flexible strips (15,16) which are supported under the following link so as to hold it in the unfurled position. Each of the free ends of the links is connected to the shutter winding spindle (5) and to the first strip of the shutter.

Description

La présente invention est relative à un dispositif de verrou automatique pour tablier de volet roulant dont l'axe d'enroulement est arrêté en rotation par le système de manoeuvre.The present invention relates to a device for automatic lock for roller shutter apron of which the winding axis is stopped in rotation by the system maneuver.

Elle vise plus précisément un verrou automatique qui assure à la fois le blocage du tablier lorsqu'il se trouve en position basse - lames emboítées les unes dans les autres - et l'impossibilité de le remonter par toute action extérieure (tentative d'effraction), lorsque la rotation du tablier n'est pas effectuée par le système de manoeuvre.More specifically, it targets an automatic lock which ensures both the locking of the apron when it found in low position - blades fitted together the others - and the impossibility of reassembling it by any external action (attempted break-in), when the deck rotation is not performed by the maneuver.

Dans le cas de la manoeuvre à treuil possédant un système de débrayage en fin de course basse, l'axe d'enroulement du tablier demeure encore libre en rotation dans le sens de remontée du tablier, le système de mécanisme de débrayage et/ou la cinématique irréversible du treuil évitent simplement l'enroulement à l'envers du tablier.In the case of a winch maneuver with a system clutch at end of travel, winding axis of the deck remains free to rotate in the direction of the apron, the mechanism mechanism declutching and / or the irreversible kinematics of the winch simply avoid winding upside down the deck.

Dans le cas des systèmes de manoeuvre à treuil mûs par un moteur électrique équipé éventuellement d'un mécanisme de roue libre qui évite de ne pas développer d'effort dans le sens de la descente du tablier pour des raisons évidentes de sécurité, de même la cinématique du mécanisme d'entraínement bloque l'axe d'enroulement dans le sens de la remontée du tablier. In the case of winch-operated maneuvering systems electric motor possibly fitted with a freewheeling which avoids not developing any effort in the direction of descent of the apron for reasons security, so the kinematics of the drive mechanism blocks the winding axis in the direction of raising the deck.

Les dispositifs connus tels que notamment celui visé dans le brevet français numéro 2 720 100, réalise un verrouillage automatique du tablier dans les coulisses, mais ces systèmes fonctionnent tous avec des axes d'enroulement bloqués en rotation par la manoeuvre, lorsque les lames du tablier se trouvent en position basse.Known devices such as in particular that referred to in French patent number 2 720 100, performs a automatic locking of the apron behind the scenes, but these systems all work with axes winding blocked in rotation by the operation, when the deck blades are in position low.

On connaít par la demande de brevet français numéro 2 754 010 un système de verrou comportant des maillons articulés les uns par rapport aux autres, à l'aide d'axes d'articulation rapportés, un ressort de torsion installé sur ces axes prenant appui entre deux pièces et les forçant à se mettre en position déployée.We know by the French patent application number 2 754 010 a locking system comprising links articulated with respect to each other, using axes hinge, a torsion spring installed on these axes resting between two parts and the forcing to get into the deployed position.

Un autre modèle est réalisé à partir d'un feuillard en acier à ressort, sur lequel est fixé au moyen de rivets des maillons qui viennent se bloquer les uns contre les autres en position déployée.Another model is made from a strip of spring steel, to which is fixed by means of rivets links that lock against each other others in the deployed position.

Quel que soit le type de modèle, il comporte divers inconvénients : ils sont composés d'un nombre de pièces important et sont donc difficiles à assembler et coûteux à réaliser. De plus, ils ne sont pas modulables sur chantier, afin d'ajuster la longueur déployée de tablier, en fonction de la configuration exacte du volet roulant. Il est courant que lors du montage du caisson de volet roulant, l'utilisateur soit obligé d'enlever ou d'ajouter une lame du tablier afin d'ajuster sa hauteur en fonction de la distance réelle entre le linteau et la tablette de la fenêtre, ce qui implique que la distance entre la première lame du tablier et le tube d'enroulement doit être optimisée afin d'obtenir un fonctionnement correct du verrou.Whatever the type of model, it includes various disadvantages: they are made up of a number of parts important and therefore difficult to assemble and expensive to achieve. In addition, they are not modular on site, in order to adjust the deployed deck length, depending on the exact configuration of the roller shutter. It is common that when mounting the shutter box rolling, the user is obliged to remove or add an apron blade to adjust its height according to the actual distance between the lintel and the shelf the window, which implies that the distance between the first blade of the deck and the winding tube should be optimized in order to obtain correct operation of the lock.

La présente invention vise donc à pallier ces inconvénients en proposant un dispositif qui garantit un ajustement de la longueur du verrou en fonction des dimensions choisies pour les caissons de volet roulant et donc en fonction du diamètre d'enroulement du tube, et qui ne nécessite aucun outillage pour assembler les différentes pièces du verrou entre elles, ces pièces pouvant être aisément démontées pour un ajustement optimal de la longueur du tablier déployé.The present invention therefore aims to overcome these disadvantages by proposing a device which guarantees a adjusting the length of the lock according to the dimensions chosen for the roller shutter boxes and therefore depending on the winding diameter of the tube, and which requires no tools to assemble the different parts of the lock between them, these parts can be easily disassembled for adjustment optimal length of the deployed deck.

A cet effet, le verrou pour volet roulant, équipé d'un axe d'enroulement du tablier selon l'invention, se caractérise en ce qu'il comporte un ensemble d'au moins deux maillons articulés entre eux par un système de charnières qui est, d'une part indémontable dans la zone de fonctionnement normal, et d'autre part provoque un arc-boutement des maillons lorsque le tablier est complètement déployé, les maillons étant pourvus en outre de lames flexibles qui viennent en appui sous le maillon suivant afin de le maintenir en position déployée, chacune des extrémités libres des maillons étant respectivement connectée à l'axe d'enroulement du tablier et à la première lame du tablier.For this purpose, the roller shutter lock, equipped with a deck winding axis according to the invention, is characterized in that it comprises a set of at least two links hinged together by a system of hinges which on the one hand cannot be dismantled in the area of normal operation, and on the other hand causes a bracing of the links when the deck is fully extended, the links being additionally provided flexible blades that come to rest under the link next to keep it in the deployed position, each of the free ends of the links being respectively connected to the winding axis of the deck and to the first blade of the deck.

Other characteristics and advantages of the present invention will emerge from the description given below, with reference to the appended drawings which illustrate an embodiment thereof devoid of any limiting character. In the figures:

Selon un mode préféré de réalisation, le dispositif formant verrou 1 selon l'invention comporte principalement une série de maillons 2, 3, 4, reliant l'axe de rotation 5 du tablier du volet roulant à l'une des lames formant ce tablier.According to a preferred embodiment, the device forming lock 1 according to the invention comprises mainly a series of links 2, 3, 4, connecting the axis of rotation 5 of the roller shutter deck at one blades forming this deck.

Ainsi, un premier maillon 2 dit d'accrochage est relié à l'axe du tablier 5. Ce maillon s'étend sous la forme d'une plaque de section droite curviligne, préférentiellement réalisée dans une matière plastique ou métallique, afin de s'adapter le plus fidèlement possible à la courbure de l'axe tubulaire 5.Thus, a first so-called link 2 is connected to the axis of the deck 5. This link extends in the form a curved straight section plate, preferably made of a plastic material or metallic, in order to adapt as faithfully as possible at the curvature of the tubular axis 5.

Le premier maillon 2 qui s'accroche au tube d'enroulement 5 présente une pluralité de fentes 6 disposées selon le sens longitudinal ou transversal dudit maillon 2, ces fentes permettent l'insertion d'un organe d'agrafage 7 qui assure la solidarisation dudit maillon 2 au tube d'enroulement 5.The first link 2 which hangs on the winding tube 5 has a plurality of slots 6 arranged according to the longitudinal or transverse direction of said link 2, these slots allow insertion of a stapling member 7 which secures said link 2 to the tube winding 5.

Comme on peut le voir sur les vues en perspective (cf. figure 4), côté face interne du maillon 2, ces fentes 6 ne sont que partiellement débouchantes, la partie centrale de celles-ci étant borgne. Les parties débouchantes permettent le passage de crochets 8, 9 provenant de l'organe d'agrafage 7, et qui coopèrent au niveau de fentes 10 réalisées selon l'axe longitudinal du tube d'enroulement 5. As can be seen in the perspective views (cf. Figure 4), internal side of the link 2, these slots 6 are only partially emerging, the part central of these being blind. The parts through holes allow the passage of hooks 8, 9 coming from the stapling member 7, and which cooperate in level of slots 10 made along the longitudinal axis of the winding tube 5.

La distance entre les deux crochets 8, 9 de l'organe d'agrafage 7 correspond au pas entre deux fentes 10 du tube d'enroulement 5.The distance between the two hooks 8, 9 of the member stapling 7 corresponds to the pitch between two slots 10 of the winding tube 5.

L'immobilisation en translation du maillon d'accrochage 2 par rapport au tube d'enroulement 5 est assurée bien entendu par l'organe d'agrafage 7, l'un des crochets 8, 9 de celui-ci servant de butée dans un sens, la butée en translation dans l'autre sens étant assurée par une patte flexible 11 (cf. figure 4) obtenue lors de la fabrication du maillon 2.Immobilization in translation of the attachment link 2 relative to the winding tube 5 is ensured well heard by the stapling member 7, one of the hooks 8, 9 of it serving as a stop in one direction, the stop in translation in the other direction being ensured by a tab flexible 11 (cf. FIG. 4) obtained during manufacture of link 2.

La patte flexible 11 s'engage à l'intérieur d'une fente 10, de manière à limiter le déplacement du maillon 2 en translation dans l'autre sens, par rapport au tube d'enroulement 5.The flexible tab 11 engages inside a slot 10, so as to limit the displacement of the link 2 in translation in the other direction, relative to the tube winding 5.

Selon un autre mode de réalisation, le maillon d'accrochage 2 au tube d'enroulement 5 dispose d'orifices 12 permettant le passage de rivets ou de vis pour la fixation sur des tubes d'enroulement 5 ne disposant pas de fentes 10 uniformément réparties sur sa longueur.According to another embodiment, the link hooking 2 to the winding tube 5 has holes 12 allowing the passage of rivets or screws for the fixing on winding tubes 5 not having slots 10 uniformly distributed over its length.

Selon une autre caractéristique du maillon d'accrochage 2, celui-ci comporte sur ses deux faces latérales 13, 14, des pattes flexibles 15, 16, de profil curviligne et venues de fabrication avec la partie centrale du maillon. Celles-ci sont conçues de manière à réaliser une poutre ou lame ressort dont l'une des extrémités est fixe, l'autre extrémité étant libre et pouvant coopérer au niveau du dessous d'un autre maillon de manière à assurer une fonction ressort entre ces deux pièces.According to another characteristic of the attachment link 2, it has on its two lateral faces 13, 14, flexible legs 15, 16, of curvilinear profile and manufacturing comings with the central part of the link. These are designed to make a beam or leaf spring, one end of which is fixed, the other end being free and able to cooperate with level of the bottom of another link so as to ensure a function stands out between these two parts.

Ces lames ressorts 15, 16 travaillent en flexion sous l'action d'un maillon intermédiaire 3 ou d'un maillon d'attelage 4 qui est connecté à l'une des faces latérales (par exemple celles de plus grandes dimensions) du maillon d'attelage 4 ou d'un maillon intermédiaire 2, la longueur de ces pattes flexibles 15, 16 est sensiblement supérieure à la largeur d'un maillon 2, 3 afin que l'extrémité libre de ces pattes dépasse de l'aplomb du maillon 2, 3 et puisse prendre contact avec le dessous du maillon suivant au niveau de son bord longitudinal.These leaf springs 15, 16 work in bending under the action of an intermediate link 3 or a link coupling 4 which is connected to one of the side faces (for example those of larger dimensions) of the coupling link 4 or an intermediate link 2, the length of these flexible legs 15, 16 is substantially greater than the width of a link 2, 3 so that the free end of these legs protrudes from the plumb of the link 2, 3 and can contact the underside of the next link at its longitudinal edge.

Le système d'accrochage entre deux maillons contigus 2, 3, 4 est le suivant : sur le maillon d'accrochage 2, on dispose sur le bord latéral 17 jouxtant la face latérale 18 d'un maillon intermédiaire 3 ou d'un maillon d'attelage 4 d'une pluralité de gonds 19 formant l'une des parties d'une charnière 20, chacun des gonds 19 étant pourvu d'une tige 21 permettant l'articulation d'une partie femelle en forme de crochet 22, venue de l'autre partie de la charnière disposée sur le maillon qui est attelé.The attachment system between two contiguous links 2, 3, 4 is as follows: on the attachment link 2, we has on the lateral edge 17 adjoining the lateral face 18 of an intermediate link 3 or a link coupling 4 of a plurality of hinges 19 forming one parts of a hinge 20, each of the hinges 19 being provided with a rod 21 allowing the articulation of a hook-shaped female part 22, coming from the other part of the hinge arranged on the link which is harnessed.

Selon une autre caractéristique avantageuse de l'invention, le verrou 1 comporte au moins un maillon intermédiaire 3 obtenu par un procédé de fabrication similaire à celui employé pour la réalisation du maillon d'accrochage 2, celui-ci présente un profil curviligne et comporte sur ses bords latéraux 13, 14 des pattes flexibles 15, 16. Celles-ci sont conformées d'une manière similaire à celles réalisées sur le maillon d'accrochage 2 et jouent également un rôle identique.According to another advantageous characteristic of the invention, the lock 1 comprises at least one link intermediate 3 obtained by a manufacturing process similar to that used to make the link attachment 2, it has a curvilinear profile and has on its lateral edges 13, 14 tabs flexible 15, 16. These are shaped in a way similar to those made on the hanging link 2 and also play an identical role.

Le maillon intermédiaire 3 est pourvu d'un système de connexion, d'une part au maillon d'accrochage 2 et d'autre part au maillon d'attelage 4.The intermediate link 3 is provided with a connection, on the one hand to the attachment link 2 and on the other hand to the coupling link 4.

Au niveau de l'articulation avec le maillon d'accrochage 2, si celui-ci est muni d'une pluralité de gonds 19, on prévoit de disposer sur le bord latéral 17 du maillon intermédiaire 3, un nombre équivalent de parties mâles formant crochets 22. Ces crochets 22 possèdent un profil tel qu'il autorise l'accrochage ou le décrochage de l'anse du crochet 22 autour des tiges 21 des gonds 19, que lorsque les deux maillons 2, 3 contigus sont repliés l'un contre l'autre.At the articulation with the attachment link 2, if the latter is provided with a plurality of hinges 19, we plans to have on the side edge 17 of the link intermediate 3, an equivalent number of male parts forming hooks 22. These hooks 22 have a profile as it authorizes the hanging or the hanging of the handle of the hook 22 around the rods 21 of the hinges 19, only when the two contiguous links 2, 3 are folded One against the other.

Afin de faciliter cette manoeuvre d'accrochage ou de décrochage, les chants 17, 18 des parties formant charnière présentent respectivement un bord arrondi 23 et un bord biseauté 24, le bord arrondi 23 glissant au contact du bord biseauté 24.In order to facilitate this hanging or stall, the songs 17, 18 of the parts forming hinge respectively have a rounded edge 23 and a beveled edge 24, the rounded edge 23 sliding at beveled edge contact 24.

Selon encore une autre caractéristique avantageuse de l'invention, le verrou 1 comporte un dernier maillon dit d'attelage 4 qui peut être relié, soit à un maillon intermédiaire 3, soit directement au maillon d'accrochage 2.According to yet another advantageous characteristic of the invention, the lock 1 comprises a last link called 4 which can be connected, either to a link intermediate 3, either directly to the attachment link 2.

Ce maillon 4 est réalisé selon une technique similaire à celle employée lors de la fabrication des maillons d'accrochage 2 et intermédiaires 3 et présente également un profil curviligne.This link 4 is produced according to a technique similar to that used during the manufacture of the links 2 and intermediate 3 and also presents a curvilinear profile.

Il se distingue cependant des précédents par le fait que les pattes flexibles 15, 16 positionnées sur chacun des bords latéraux sont limitées à de simples zones en saillie 25 qui reposent sur l'extrémité et au-dessus des pattes flexibles 15, 16 venues du maillon intermédiaire 3 ou du maillon d'accrochage 2.It differs from the previous ones, however, by the fact that the flexible tabs 15, 16 positioned on each of the side edges are limited to simple areas in projection 25 which rest on the end and above the flexible legs 15, 16 coming from the intermediate link 3 or the hanging link 2.

Le maillon d'attelage 4 comporte des moyens de connexion à un autre maillon contigu, au niveau d'un de ses bords latéraux 17, ceux-ci étant par exemple des parties mâles en forme de crochets 22 qui ne peuvent se décrocher ou s'accrocher aux parties femelles correspondantes présentes sur l'autre maillon, qu'à la condition que les maillons 2, 3, 4 soient repliés l'un sur l'autre.The coupling link 4 comprises connection means to another contiguous link, at one of its edges side 17, these being for example male parts in the form of hooks 22 which cannot be detached or cling to the corresponding female parts present on the other link, only on condition that the links 2, 3, 4 are folded over each other.

Les moyens de connexion entre deux maillons sont définis de telle sorte que l'assemblage est indémontable dans sa zone de fonctionnement normal (c'est-à-dire entre la position complètement enroulée sur le tube et la position complètement déployée), sans le recours à des outils spécifiques permettant ainsi une adaptation très aisée en longueur du système.The means of connection between two links are defined so that the assembly cannot be dismantled in its normal operating area (i.e. between the fully wound position on the tube and position fully deployed), without the use of tools specific allowing a very easy adaptation in length of the system.

Le troisième maillon 4 est relié à la première lame du tablier qui chemine au travers de la tulipe solidaire de la coulisse du châssis du volet roulant.The third link 4 is connected to the first blade of the apron that walks through the tulip the slide of the roller shutter frame.

En fonction des dimensions du caisson ou du diamètre d'enroulement du tube 5 devant recevoir le tablier du volet roulant, le dispositif de verrou selon l'invention sera modifié, par le retrait ou par l'ajout d'au moins un maillon intermédiaire, afin d'allonger ou de raccourcir le système.Depending on the dimensions of the box or the diameter winding tube 5 to receive the apron of roller shutter, the lock device according to the invention will be modified, by removing or adding at least one intermediate link, to lengthen or shorten the system.

On réalise une liaison rigide entre le tube 5 et la première lame du tablier grâce à l'ensemble des maillons 2, 3, 4 qui viennent en butée positive l'un contre l'autre, afin de former un ensemble rigide en position déroulée du tube.A rigid connection is made between the tube 5 and the first blade of the deck thanks to all the links 2, 3, 4 which come into positive abutment one against the other, in order to form a rigid whole in position unwound from the tube.

Le mouvement de l'ensemble des maillons se décompose de la manière suivante : le premier maillon 2 demeure solidaire du tube d'enroulement 5 grâce à l'organe d'agrafage 7, le maillon intermédiaire 3 ou le maillon d'attelage 4 s'articule autour de son axe 21, jusqu'au moment où il vient en butée contre le maillon d'accrochage 2.The movement of all the links breaks down the following way: the first link 2 remains integral with the winding tube 5 thanks to the member 7, the intermediate link 3 or the link hitch 4 is articulated around its axis 21, until when it comes into abutment against the link hanging 2.

Le maillon intermédiaire 3, qui peut être éventuellement ôté en fonction de la configuration choisie, est connecté au maillon d'attelage 4 qui est relié à la première lame du tablier. A cette fin, on utilise l'extrémité du maillon d'attelage 4 qui est pourvue d'une partie en gorge 26 formant glissière pour une partie correspondante de la première lame du tablier. The intermediate link 3, which can be optionally removed depending on the configuration chosen, is connected to the coupling link 4 which is connected to the first blade of the apron. For this purpose, we use the end of the coupling link 4 which is provided with a part in groove 26 forming slide for a corresponding part of the first blade of the deck.

Selon une autre caractéristique de l'invention, le verrou 1 formé d'une juxtaposition d'un maillon d'accrochage 2 et d'attelage 4 et éventuellement d'au moins un maillon intermédiaire 3, s'arc-boute lorsque le tablier du volet roulant est complètement descendu dans les coulisses et que la dernière lame repose sur la tablette de la fenêtre. Dans cette position, les lames se repoussent mutuellement jusqu'à produire un effet de levier sur le maillon d'attelage 4, qui répercute l'effort sur les maillons qui lui sont attelés. Etant donné que l'axe d'enroulement du tablier 5 n'est pas libre en rotation, il s'ensuit un phénomène de flexion.According to another characteristic of the invention, the lock 1 formed of a juxtaposition of a hanging link 2 and coupling 4 and possibly at least one link intermediate 3, buckles when the shutter curtain rolling down completely backstage and that the last blade rests on the shelf of the window. In this position, the blades repel mutually to produce leverage on the coupling link 4, which transfers the force to the links attached to it. Since the axis winding of the deck 5 is not free to rotate, there follows a phenomenon of bending.

Afin de limiter en amplitude le mouvement d'arc-boutement des maillons 2, 3, 4 l'un par rapport à l'autre, on prévoit de disposer des faces biseautées 27, 28 formant butées, sur le chant du bord latéral principal, de chaque côté de chacun des maillons (on se reportera à la figure 5) et au niveau des zones qui vont être en contact.In order to limit the amplitude of the bracing movement links 2, 3, 4 relative to each other, we plans to have bevelled faces 27, 28 forming stops on the edge of the main lateral edge of each side of each of the links (refer to the figure 5) and at the level of the zones which will be in contact.

Selon un autre mode de réalisation, le maillon d'accrochage 2 et le maillon intermédiaire seront réalisés à partir d'un même moule et seront donc identiques.According to another embodiment, the link hook 2 and the intermediate link will be made from the same mold and will therefore be identical.

L'invention telle que décrite ci-dessus offre de multiples avantages : elle concilie tous les paramètres de fonctionnement (la hauteur optimale du tablier, l'arc-boutement du verrou, un déploiement stable de la succession de maillons de part l'utilisation des lames flexibles formant ressort), cette manoeuvre pouvant être définie en atelier et affinée sur le chantier, par l'ajout à l'une des extrémités des deux maillons principaux formant verrou, de maillons supplémentaires, afin de s'adapter au gabarit du caisson du volet roulant, quel que soit le type d'organe de manoeuvre (à treuil ou à moteur électrique), le réglage finaal sur le chantier s'effectue automatiquement grâce aux lumières ménagées dans l'un des maillons du verrou ce qui permet l'ajustage final en longueur du mécanisme en fonction de la taille, sans avoir à déposer le volet .The invention as described above offers multiple advantages: it reconciles all parameters of operation (the optimal height of the deck, the bracing of the lock, a stable deployment of the succession of links through the use of blades flexible spring), this maneuver can be defined in the workshop and refined on site, by adding at one end of the two links main lock, additional links, in order to adapt to the size of the roller shutter box, whatever the type of operating device (winch or with electric motor), the final adjustment on site takes place automatically thanks to the lights in one of the links of the lock which allows adjustment final length of the mechanism depending on the size, without having to remove the flap.

Il demeure bien entendu que la présente invention n'est pas limitée aux exemples de réalisation décrits et représentés ci-dessus, mais qu'elle en englobe toutes les variantes.Of course, the present invention is not not limited to the embodiments described and shown above, but that it includes all variants.
