The apron has driving units (10) provided at a level of lateral ends (7, 8) of orientable strips (2A) for controlling a deployment and folding of the apron. Transmission units (6) execute a stroke to control unlocking of strip blocking units (19) e.g. lock, blocking strips in closing position and opening controlling stroke to control an opening of the strips in cutout position. The transmission units execute the pushing stroke, for pushing the strips along a direction of a plane of the apron, and blocking units controlling stroke for controlling an opening of the strips.

Description

L'invention concerne un tablier pour système d'occultation et/ou de fermeture de bâtiment comportant des lames orientables conçues aptes à être repoussées dans une position ajourée ou de fermeture sous l'impulsion de moyens de transmission adaptés. L'invention concerne encore un volet roulant équipé d'un tel tablier.The invention relates to an apron for concealment system and / or closure of building comprising adjustable blades designed to be pushed into a perforated or closed position under the impulse of suitable transmission means. The invention also relates to a roller shutter equipped with such an apron.

L'invention entre dans le domaine des systèmes de fermeture du bâtiment, de type système d'occultation, tels que des volets roulants, stores à lames ou similaires.The invention is in the field of closure systems of the building, type of occultation system, such as roller shutters, blinds blades or the like.

L'invention concerne plus particulièrement de tels systèmes comportant un tablier à lames orientables pour leur permettre d'occuper une position d'occultation et au moins une position ajourée et/ou d'aération.The invention relates more particularly to such systems comprising an apron with steerable blades to enable them to occupy an occultation position and at least one perforated position and / or aeration.

S'il existe d'ores et déjà des tabliers comportant de telles lames orientables, celles-ci sont maintenues latéralement au moyen de mécanismes d'entraînement adjacents ou intégrés à des coulisses de guidage. Au travers de ce mécanisme d'entraînement lesdites lames sont susceptibles d'être orientées de manière à s'étendre sensiblement dans un même plan tout en venant légèrement se chevaucher les unes par rapport aux autres pour occulter une ouverture ou, au contraire, pour s'écarter de ce plan et favoriser le passage de la lumière.If there are already aprons with such steerable blades, they are held laterally by means of drive mechanisms adjacent or integrated with guide rails. Through this drive mechanism, said blades are capable of being oriented so as to extend substantially in the same plane while slightly overlapping each other to conceal an opening or, on the contrary, for move away from this plane and favor the passage of light.

Il est d'ores et déjà connu au travers de l'état de la technique un tablier de store ou similaire comportant des lames subdivisées dans le sens longitudinal en deux parties de lames articulées entre elles. Si la première partie de lame est fixe au sens où elle peut s'incliner pour s'écarter du plan du tablier, la seconde partie de lame peut, au contraire pivoter pour conférer à ce tablier une position ajourée. Pour cela, ladite première lame est rendue solidaire, à ses extrémités, de premiers moyens de transmission présentant une course à vide par rapport à des seconds moyens de transmission dont sont rendues solidaires les extrémités des secondes lames.It is already known through the state of the art a blind apron or the like comprising blades divided in the longitudinal direction into two parts of blades hinged together. If the first blade portion is fixed in the sense that it can tilt to deviate from the plane of the deck, the second blade portion can, instead rotate to give the apron a perforated position. For this, said first blade is secured, at its ends, first transmission means having a vacuum stroke relative to second transmission means which are secured to the ends of the second blades.

Dans ce contexte, on connaît, par le document DE-35 29 418 , un store dont les lames sont subdivisées en deux portions de lames et repliables autour d'une ligne de pliage médiane. Ces lames sont rendues solidaires à leurs extrémités de câbles d'entraînement.In this context, we know from the document DE-35 29,418 , a blind whose blades are subdivided into two portions of blades and foldable around a median fold line. These blades are secured to their ends of drive cables.

On connaît également par le document DE-10 42 869 un dispositif de store comportant des lames portant, à leurs extrémités, sensiblement dans le prolongement de leur axe médian, des pivots fixés sur une paire de sangles. Ainsi, ces lames sont pivotantes autour de leur axe médian de manière à pouvoir occuper une première position d'occultation dans laquelle ces lames sont maintenues sensiblement dans un même alignement vertical ou une position ajourée dans laquelle, au contraire, elles sont écartées de ce plan par pivotement autour de leur axe médian.It is also known from the document DE-10 42 869 a blind device comprising blades bearing, at their ends, substantially in the extension of their central axis, pivots fixed on a pair of straps. Thus, these blades are pivotable about their median axis so as to occupy a first occultation position in which these blades are maintained substantially in the same vertical alignment or a perforated position in which, on the contrary, they are spaced from this plane by pivoting about their median axis.

Dans le document DE-1.509.213 , il est repris ce même principe de store à lames pivotantes. Toutefois, dans un mode de réalisation particulier, ces lames sont rendues solidaires, en bordure d'extrémité supérieure et de manière pivotante de moyens de transmission définis pour autoriser une mobilité relative des lames entre elles dans la direction de déploiement ou de repliement. Au travers de cette mobilité relative les lames peuvent, selon le cas, être resserrées ou écartées les unes par rapport aux autres. Sous l'effet du resserrement des lames des biellettes, reliant une lame à une lame suivante à la manière d'une genouillère repoussent cette dernière dans une position ajourée, écartée du plan d'alignement occupé par ces lames en position d'occultation.In the document DE-1509213 , it is taken again this same principle of awning with pivoting blades. However, in a particular embodiment, these blades are made integral, at the upper end edge and pivotally defined transmission means to allow relative mobility of the blades together in the direction of deployment or folding. Through this relative mobility the blades can, depending on the case, be tightened or spaced relative to each other. Under the effect of tightening the blades of the rods, connecting a blade to a next blade in the manner of a toggle push the latter in a perforated position, spaced from the alignment plane occupied by these blades in the occultation position.

Dans le document DE-1.659.907 , il est décrit une solution tout à fait similaire et il est plus particulièrement visible la liaison articulée des lames sur les moyens de transmission s'étendant dans les coulisses latérales de guidage.In the document DE-1659907 it is described a solution quite similar and it is more particularly visible the articulated connection of the blades on the transmission means extending in the lateral guides of guide.

On connaît encore par le document DE-948 443 un dispositif d'occultation de type volet roulant dont les lames sont rendues solidaires, à leurs extrémités latérales, de chaînes d'entraînement à maillons. Chaque maillon est constitué de deux lames qui, selon le cas, sont télescopiques l'une par rapport à l'autre ou articulées entre elles, permettant de conférer au tablier de ce dispositif d'occultation une position ajourée, que ce soit par écartement des lames entre elles ou par basculement.We still know from the document DE-948,443 a shutter type blind device whose blades are secured, at their lateral ends, link drive chains. Each link consists of two blades which, depending on the case, are telescopic with respect to one another or hinged together, making it possible to give the apron of this occultation device a perforated position, whether by spacing the blades between them or by tilting .

On connaît encore, par le document EP-460 521 , un dispositif de fermeture de type volet roulant comportant des lames dont certaines sont orientables, ceci à la base d'un principe de fonctionnement équivalent à celui décrit dans le document DE-5.509.213 , si ce n'est que les lames ne sont pas solidaires de moyens de transmission spécifiques. Ici, lesdites lames sont reliées par paire, chaque paire de lames comportant une lame supérieure fixe et une lame inférieure pivotante, celle-ci étant reliée par l'intermédiaire d'une biellette à la lame supérieure fixe de la paire de lames suivante et ainsi de suite.We still know, by the document EP-460 521 , a rolling shutter type closure device comprising blades, some of which are orientable, this being the basis of an operating principle equivalent to that described in the document DE-5509213 , except that the blades are not secured to specific transmission means. Here, said blades are connected in pairs, each pair of blades having a fixed upper blade and a pivoting lower blade, the latter being connected via a link to the fixed upper blade of the next pair of blades and thus right now.

Lorsque le tablier de ce dispositif d'occultation est sous tension, les différentes lames se positionnent dans un même plan d'alignement. Au contraire, en fin de déploiement du tablier et sous l'effet d'une compression imprégnée à ce dernier, les lames pivotantes sont repoussées dans une position étendue, ceci par l'intermédiaire de biellettes agissant telle des genouillères.When the apron of this occultation device is under tension, the different blades are positioned in the same alignment plane. On the contrary, at the end of deployment of the apron and under the effect of a compression impregnated with the latter, the pivoting blades are pushed into an extended position, this by means of rods acting as knee pads.

Plus exactement, sous l'effet de la compression, les lames fixes de deux paires de lames qui se suivent ont tendance à se rapprocher ce qui est rendu possible par les différentes liaisons articulées entre : lames orientables et lames fixes ; lames fixes et biellettes ; biellettes et lames orientables.More precisely, under the effect of compression, the fixed blades of two pairs of blades that follow each other tend to approach what is made possible by the different links articulated between: orientable blades and fixed blades; fixed blades and links; connecting rods and adjustable blades.

On connaît encore par le document FR-1.106.629 un dispositif de store à lames orientables, celles-ci étant susceptibles d'être écartées du plan de déploiement du store sous l'action, là encore, de biellettes agissant telles des genouillères sous l'effet d'une compression imprimée au store.We still know from the document FR-1106629 a blind device with adjustable blades, the latter being likely to be removed from the blind deployment plan under the action, again, connecting rods acting as knee pads under the effect of a printed compression to the blind.

Quel que soit le mode de réalisation connu au travers de l'état de la technique, le principe de fonctionnement est quasiment toujours le même. Sous l'effet d'une traction exercée sur le tablier, les lames orientables se referment et regagnent leur position d'alignement dans le plan du tablier. Contrairement, sous l'effet d'une compression ou encore d'une course à vide entre, d'une part, des moyens d'entrainement agissant sur les lames fixes de ce tablier pour assurer son déploiement ou son repliement et, d'autre part, des moyens de transmission intervenant plus particulièrement sur les lames orientables, celles-ci sont repoussées en dehors du plan du tablier sous l'action d'une biellette agissant telle une genouillère.Whatever the embodiment known through the state of the art, the operating principle is almost always the same. Under the effect of a traction exerted on the deck, the swivel blades close and return to their alignment position in the plane of the deck. Unlike, under the effect of compression or a vacuum stroke between, on the one hand, drive means acting on the fixed blades of the deck to ensure its deployment or folding and other on the other hand, transmission means intervening more particularly on the steerable blades, they are pushed out of the plane of the deck under the action of a connecting rod acting as a toggle.

A ce sujet, celle-ci est définie par un point d'articulation médian de la biellette sur la lame articulée, et deux points d'articulation extrêmes, celui, d'une part, de la lame articulée sur une lame fixe précédente ou sur des moyens d'entrainement adaptés et, d'autre part, le point d'articulation de la biellette, là encore, sur une lame fixe suivante ou sur des moyens de transmission. Pour que cela fonctionne et que la genouillère puisse se replier dans la bonne direction, le point d'articulation central est nécessairement décalé dans cette direction dans laquelle doit être repoussée la lame orientable, ceci par rapport au plan dans lequel s'inscrivent les deux articulations extrêmes.In this regard, it is defined by a median articulation point of the rod on the articulated blade, and two extreme points of articulation, that, on the one hand, of the blade articulated on a previous fixed blade or on suitable driving means and, on the other hand, the point of articulation of the rod, again, on a next fixed blade or on transmission means. For this to work and that the knee can be folded in the right direction, the central articulation point is necessarily shifted in this direction in which the swivel blade must be pushed, this compared to the plane in which the two joints are inscribed. extremes.

L'inconvénient d'une telle disposition consiste en ce qu'une lame orientable peut être très facilement saisie et repoussée ou tirée depuis sa position d'occultation dans sa position d'aération, justement en raison de cette genouillère prédisposée à se plier pour permettre cette ouverture de la lame orientable.The disadvantage of such an arrangement is that a steerable blade can be very easily grasped and pushed or pulled from its occultation position in its aeration position, precisely because of this knee prone to bend to allow this opening of the swivel blade.

En cas de tentative d'effraction, l'intervenant, constatant une moindre résistance des lames orientables, aura tendance à soulever l'une ou l'autre d'entre elles pour tenter d'ouvrir le tablier et s'introduire dans l'habitation. Même si sa tentative échoue, il y a de fortes chances que le tablier soit abîmé du fait de ces agissements.In case of attempted break-in, the worker, noting a less resistance of the adjustable blades, will tend to lift one or the other of them to try to open the deck and get into the house . Even if his attempt fails, there is a good chance that the apron will be damaged by these actions.

De même, plus le point d'articulation central de la genouillère se rapproche du plan dans lequel s'inscrivent les points d'articulation extrêmes, plus l'action de la biellette sur la lame orientable tend à s'annuler. Il en résulte un mauvais maintien de cette lame orientable qui peut alors battre au vent. De plus, si elle ne peut être convenablement plaquée sur une lame suivante, le tablier ne peut procurer un degré d'occultation convenable.Likewise, the closer the central articulation point of the knee joint is to the plane in which the extreme articulation points are inscribed, the more the action of the link on the orientable blade tends to cancel out. This results in a bad maintenance of this steerable blade that can then beat the wind. In addition, if it can not be properly plated on a next blade, the deck can not provide a degree of occlusion suitable.

On citera encore le document EP-A-0 687 793 , où l'on dispose, d'un côté, d'un volet roulant constitué de lames qui, en traction, s'accrochent les unes aux autres, tandis qu'en compression, se décrochent pour permettre leur basculement. Ces lames sont pourvues à leurs extrémités d'embouts venant coulisser, en phase de déploiement du tablier, le long d'une chaîne implantée dans les coulisses latérales de guidage. Cette chaîne est constituée d'une succession de rotors et de blocs intercalaires. Une fois le tablier déployé, les oreilles dont sont équipés les embouts à leurs extrémités coïncident avec les rotors dont la commande en rotation, par l'intermédiaire de moyens de transmission adaptés, permet le basculement des lames en position ajourée.We will still quote the document EP-A-0 687 793 , where we have, on one side, a roller shutter consisting of blades which, in tension, cling to each other, while in compression, unhook to allow their tilting. These blades are provided at their end ends with sliding ends, in the deployment phase of the apron, along a chain implanted in the lateral guide slides. This chain consists of a succession of rotors and intermediate blocks. Once the apron is deployed, the ears which are equipped with the ends at their ends coincide with the rotors whose rotational control, via suitable transmission means, allows the tilting of the blades open position.

C'est dans le cadre d'une première démarche inventive que l'on a imaginé qu'au cours du déplacement relatif imprimé entre deux lames successives, déplacement assimilé à une compression du tablier dans la description de l'état de la technique cité plus haut, ceci pour commander l'ouverture d'une lame orientable, ce déplacement relatif se décompose en une première course de déverrouillage, puis une seconde course de commande de pivotement de cette lame orientable. A l'inverse, il a été imaginé que sous l'effet d'une traction exercée sur le tablier, les lames orientables soient, non seulement, ramenées dans le plan de ce tablier, mais qu'intervienne aussi un verrouillage des lames entre elles de manière à empêcher leur basculement en position ajourée.It is within the framework of a first inventive step that it has been imagined that during the relative displacement printed between two successive blades, displacement assimilated to a compression of the deck in the description of the state of the art cited above. high, this to control the opening of a steerable blade, this relative movement is decomposed into a first release stroke, and a second pivot control stroke of the swivel blade. Conversely, it has been imagined that under the effect of traction exerted on the deck, the steerable blades are not only brought back into the plane of this deck, but that there is also a locking blades between them in order to prevent their tilting in open position.

Dans le cadre d'une seconde démarche inventive, l'on a pensé profiter de cette course à vide de verrouillage et de déverrouillage, pour intervenir directement sur le point d'articulation médian de la genouillère, autrement dit sur le point d'articulation de la biellette sur la lame orientable pour, selon le cas, exercer une action de traction ou de poussée sur la lame orientable en vu de plaquer celle-ci en position de fermeture ou au contraire pour repousser cette lame en direction de sa position ajourée.As part of a second inventive step, it was thought to take advantage of this vacuum stroke of locking and unlocking, to intervene directly on the median articulation point of the knee, ie on the point of articulation of the link on the swiveling blade for, as the case may be, to exert a traction or pushing action on the steerable blade in view of plating thereof in the closed position or on the contrary to push this blade towards its open position.

En somme, au travers de cette action sur l'articulation médiane de la genouillère, celle-ci ne doit pas nécessairement être pré pliée pour la commande d'ouverture d'une lame orientable, mais peut être repoussée dans le plan des deux articulations extrêmes d'où résulte une parfaite rigidité du tablier et un maintien en position d'occultation des lames orientables. Dans ce contexte, ce point d'articulation médian peut même être repoussé de l'autre côté de plan passant par les deux articulations extrêmes, c'est à dire dans une direction opposée à celle dans laquelle doit se replier normalement la genouillère. Aussi, en cas de tentative d'effraction consistant à intervenir directement sur le tablier en tentant de le soulever, les lames orientables, plutôt que d'avoir tendance à s'ouvrir sous l'effet du pliage de la genouillère, viennent se plaquer encore plus fortement contre les autres lames. Le tablier gagne par conséquent en sécurité, en rigidité et en étanchéité à la lumière.In short, through this action on the medial joint of the toggle joint, it does not necessarily have to be pre-folded for the opening control of an orientable blade, but can be pushed back in the plane of the two extreme joints. from which results a perfect rigidity of the apron and a holding in position of occultation of the adjustable blades. In this context, this medial articulation point can even be pushed to the other side of the plane passing through the two extreme joints, that is to say in a direction opposite to that in which the knee should normally be folded. Also, in case of attempted break-in consisting of intervening directly on the deck while trying to lift it, the adjustable blades, rather than having a tendency to open under the effect of the folding of the toggle, come flat again more strongly against other blades. The apron therefore gains safety, rigidity and light-tightness.

A cet effet, l'invention concerne un Tablier pour système d'occultation et/ou de fermeture de bâtiment comportant des lames orientables conçues aptes à être repoussées dans une position ajourée ou de fermeture sous l'impulsion de moyens de transmission adaptés, caractérisé par le fait :

  • ■ qu'il comporte des moyens d'entraînement au niveau des extrémités latérales des lames pour la commande de déploiement et repliement dudit tablier;
  • ■ que les moyens de transmission sont associés auxdits moyens d'entraînement avec une mobilité relative par rapport à ces derniers, pour, en position déployée du tablier, commander, selon le cas, l'ouverture ou la fermeture des lames orientables ;
  • ■ que ces moyens de transmission sont conçus aptes à exécuter, pour la commande d'ouverture en position ajourée des lames orientables, une première course pour la commande de déverrouillage de moyens de blocage desdites lames en position de fermeture, suivies d'une course de commande d'ouverture et, inversement, pour la commande de fermeture des lames orientables, une première course pour repousser ces dernières en direction du plan du tablier suivi d'une course de commande de verrouillage desdits moyens de blocage.
To this end, the invention relates to an apron for a concealment system and / or a building closure comprising adjustable blades designed to be pushed into a perforated or closed position under the impetus of suitable transmission means, characterized by the fact :
  • ■ it comprises drive means at the lateral ends of the blades for deployment control and folding said apron;
  • That the transmission means are associated with said drive means with a relative mobility relative to the latter, for, in the deployed position of the apron, order, as appropriate, the opening or closing of the steerable blades;
  • ■ that these transmission means are designed capable of executing, for opening control openwork position of the steerable blades, a first stroke for the unlatching control means for locking said blades in the closed position, followed by an opening control stroke and, conversely, for the closing control of the steerable blades, a first stroke to push the latter towards the plane of the apron followed by a locking control stroke of said locking means.

Les avantages découlant de la présente invention consistent en ce qu'en position d'occultation du tablier les lames orientables sont parfaitement maintenues refermées par l'intermédiaire de moyens de blocage adaptés et non simplement retenus dans cette position par l'intermédiaire des moyens de transmission.The advantages deriving from the present invention consist in that in the concealment position of the apron the orientable blades are perfectly kept closed by means of appropriate locking means and not simply held in this position by means of the transmission means. .

Tel que représenté dans les figures des dessins ci-joints, la présente invention concerne un tablier 1 pour système d'occultation et/ou de fermeture de bâtiment, tel qu'un volet roulant comme souhaite d'ailleurs le représenter, schématiquement, la figure 1.As shown in the figures of the accompanying drawings, the present invention relates to an apron 1 for occultation and / or closure system of a building, such as a shutter as it wishes to represent it, schematically, the figure 1 .

Un tel tablier 1 comporte une pluralité de lames 2 dont au moins certaines 2A sont orientables.Such an apron 1 comprises a plurality of blades 2, at least some of which 2A are orientable.

Dans le mode de réalisation représenté sur les figures ci-jointes, cette lame orientable 2A est montée articulée au niveau de son bord supérieur 3, en bordure inférieure 4 d'une lame fixe 2B précédente.In the embodiment shown in the accompanying figures, this steerable blade 2A is articulated at its upper edge 3, at the bottom edge 4 of a fixed blade 2B previous.

Par ailleurs, au niveau de son bord inférieur 5, cette lame orientable 2A vient en recouvrement d'une lame fixe 2B suivante.Moreover, at its lower edge 5, this swiveling blade 2A overlaps a fixed blade 2B following.

Une telle lame orientable 2A est conçue apte à être repoussée dans la position ajourée comme visible dans la figure 5 ou de fermeture comme représenté dans la figure 2, ceci sous l'impulsion de moyens de transmission 6 intervenant, préférentiellement, sur l'une au moins des extrémités latérales 7, 8 d'une telle lame orientable 2A. Ainsi, ces moyens de transmission 6 peuvent prendre position dans des coulisses latérales de guidage 9 guidant le tablier 1 lors de son déploiement ou repliement.Such a steerable blade 2A is designed to be pushed into the perforated position as visible in the figure 5 or closing as shown in the figure 2 , this under the influence of transmission means 6 intervening, preferably on at least one of the lateral ends 7, 8 of such a steerable blade 2A. Thus, these transmission means 6 can take position in lateral guiding slides 9 guiding the deck 1 during its deployment or refolding.

Comme visible par ailleurs sur les figures 2 et 5, des moyens d'entraînement 10 sont prévus au niveau de ces extrémités latérales 7, 8 des lames 2. Ces moyens d'entraînement ont pour fonction d'assurer le déploiement, ainsi que le repliement du tablier 1. Tout particulièrement, sur ces moyens d'entraînement 10 sont fixées les extrémités latérales des lames fixes 2B si le tablier 1 en comporte, tout comme on peut y solidariser, de manière pivotante, les lames orientables 2A plutôt que de les monter articulées sur de telles lames fixes 2B comme dans l'exemple illustré dans les dessins. La présente invention s'applique à chacune de ces solutions.As can be seen elsewhere on figures 2 and 5 , drive means 10 are provided at these lateral ends 7, 8 of the blades 2. These drive means have the function of ensuring the deployment and the folding of the deck 1. In particular, on these means 10 are secured to the lateral ends of the fixed blades 2B if the apron 1 has, as can be pivotally secured to the pivotable blades 2A rather than articulated on such fixed blades 2B as in l example shown in the drawings. The present invention applies to each of these solutions.

Ainsi, ces moyens d'entraînement 10 peuvent emprunter différentes formes de réalisation. Ils ont été représentés sous forme d'une chaîne 11 à maillons 12. A chaque maillon 12 correspondant, préférentiellement, une lame 2A, 2B.Thus, these drive means 10 may take different embodiments. They have been represented in the form of a chain 11 with links 12. At each corresponding link 12, preferably, a blade 2A, 2B.

Evidemment, de tels moyens d'entraînement 10 peuvent emprunter d'autres formes de réalisation et en particulier, ils pourraient être conçus sous forme d'une bande semi-rigide voire d'un feuillard métallique.Obviously, such drive means 10 may borrow other embodiments and in particular they could be designed in the form of a semi-rigid band or even a metal strip.

Comme il est encore visible dans les figures 2 et 5, à ces moyens d'entraînement 10 peuvent être associés les moyens de transmission 6, ceux-ci présentant une mobilité relative par rapport auxdits moyens d'entraînement 10 justement pour, en position déployée du tablier 1, commander, selon le cas, l'ouverture ou la fermeture des lames orientables 2A.As it is still visible in figures 2 and 5 to these drive means 10 may be associated the transmission means 6, the latter having a relative mobility with respect to said drive means 10 precisely for, in the deployed position of the apron 1, to control, as the case may be, the opening or closing of the directional blades 2A.

Ainsi, ces moyens de transmission 6, se présentent, là encore, de manière avantageuse, sous forme d'une bande semi-rigide ou d'un feuillard métallique 13 monté mobile en translation, voire guidé sur les moyens d'entraînement 10. De tels moyens de transmission peuvent emprunter bien d'autres formes de réalisation, en particulier celle d'une sangle, d'une tige, d'une chaine, etc...Thus, these transmission means 6 are, again, advantageously in the form of a semi-rigid strip or a metal strip 13 mounted to move in translation, or even guided on the drive means 10. such transmission means can borrow many other embodiments, in particular that of a strap, a rod, a chain, etc ...

Les moyens de transmission 6 comportent également une biellette 14 dont une extrémité est montée pivotante sur la bande ou le feuillard 13, tandis que l'extrémité opposée de cette biellette 14 est rendue solidaire, également de manière articulée, d'une lame orientable 2A.The transmission means 6 also comprise a rod 14 whose one end is pivotally mounted on the strip or the strip 13, while the opposite end of the rod 14 is secured, also in an articulated manner, an orientable blade 2A.

Ainsi, comme souhaite le représenter la figure 4, cette biellette 14, avec son point d'articulation P1 sur la bande ou le feuillard 13 et celui P2 sur la lame orientable 2A, d'une part, et cette lame orientable 2A, avec son point l'articulation P3 sur une lame fixe 2B précédente, constituent une genouillère qui, par flexion, conduit à repousser ladite lame orientable 2A dans une position ajourée.Thus, as wishes to represent it the figure 4 , this rod 14, with its articulation point P1 on the strip or the strip 13 and the P2 on the swivel blade 2A, on the one hand, and this swiveling blade 2A, with its point the joint P3 on a fixed blade 2B preceding, constitute a toggle which, by bending, leads to push said swivel blade 2A in a perforated position.

Selon un mode de réalisation avantageux, la liaison articulée entre une lame orientable 2A et une biellette 14 montée le long de la bande ou du feuillard 13 peut être assurée au travers d'un embout 15 rapporté par emmanchement et/ou sertissage et/ou collage à une extrémité latérale 7, 8 d'une telle lame orientable 2A. Ainsi, cet embout 15 comporte, avantageusement, une branche 16 s'étendant dans le prolongement de la lame 2A et portant à son extrémité une fourche 17 définissant un palier support de l'axe d'articulation 18 de la biellette 14.According to an advantageous embodiment, the articulated connection between an orientable blade 2A and a rod 14 mounted along the strip or the strip 13 can be provided through a tip 15 attached by fitting and / or crimping and / or bonding at a lateral end 7, 8 of such an orientable blade 2A. Thus, this tip 15 advantageously comprises a branch 16 extending in the extension of the blade 2A and carrying at its end a fork 17 defining a support bearing of the hinge pin 18 of the rod 14.

Selon une particularité de l'invention, lesdits moyens de transmission 6 sont conçus aptes à exécuter, pour la commande d'ouverture en position ajourée d'une lame orientable 2A, une première course C pour la commande de déverrouillage de moyens de blocage 19 de ladite lame orientable 2A en position de fermeture, suivie d'une course complémentaire de commande d'ouverture de cette lame orientable 2A dans une position écartée du plan P du tablier 1. Inversement, pour la commande de fermeture, ces moyens de transmission 6 sont conçus pour, sur une première course, repousser les lames orientables 2A à nouveau en direction du plan P du tablier 1 suivi de la course C de commande de verrouillage desdits moyens de blocage 19.According to one particularity of the invention, said transmission means 6 are designed capable of executing, for opening control in the open position of an orientable blade 2A, a first stroke C for unlocking control of locking means 19 of said swiveling blade 2A in the closed position, followed by a complementary opening control stroke of this swiveling blade 2A in a position spaced from the plane P of the deck 1. Conversely, for the closing control, these transmission means 6 are designed for, on a first stroke, pushing the adjustable blades 2A again in the direction of the plane P of the deck 1 followed by the stroke C of the locking control of said locking means 19.

Selon un mode de réalisation préférentiel, les moyens de blocage 19 sont conçus en forme d'un verrou comportant au moins un pêne 20 et au moins une gâche 21, l'un, préférentiellement le premier, associé à la biellette 14 et le second, dans ce cas la gâche 21, rendu solidaire, en translation, de la ou des lames fixes 2B du tablier 1. Dans la solution visible sur les figures, cette ou ces gâches 21 sont associées aux moyens d'entraînement 10 dont sont solidaires, à leurs extrémités latérales, lesdites lames fixes 2B, voire les lames orientables 2A.According to a preferred embodiment, the locking means 19 are designed in the form of a lock comprising at least one bolt 20 and at least one striker 21, one, preferably the first, associated with the rod 14 and the second, in this case the striker 21, made integral, in translation, with the fixed blade (s) 2B of the apron 1. In the solution visible in the figures, this or these strikers 21 are associated with the drive means 10 which are secured to, their lateral ends, said fixed blades 2B, or even the steerable blades 2A.

Ainsi, selon un mode de réalisation correspondant aux figures 2, 3 et 5, la biellette 14 porte, de part et d'autre de son plan médian longitudinal un tel pêne 20 conçu apte à venir s'engager dans une gâche 21, sous forme de découpes 22, ménagées dans des parois longitudinales 23 des moyens d'entrainement 10, en l'occurrence d'un maillon 12 bordant, dans le sens de leur déplacement, les moyens de transmission 6, en l'occurrence la bande ou le feuillard 13 portant ladite biellette 14.Thus, according to an embodiment corresponding to figures 2 , 3 and 5 , the link 14 carries, on either side of its longitudinal median plane, such a bolt 20 designed adapted to engage in a keeper 21, in the form of cutouts 22, formed in longitudinal walls 23 training means 10, in this case a link 12 bordering, in the direction of their displacement, the transmission means 6, in this case the strip or the strip 13 carrying said link 14.

De manière tout particulièrement avantageuse, la ou les gâches 21 sont conçues à la manière d'une came et comportent une rampe 24, comme visible sur la figure 3, conçue apte, sous l'effet d'un déplacement longitudinal imprimé aux moyens de transmission 6, à conférer, au travers de sa coopération avec un pêne 20, un déplacement à ladite biellette 14 à composante perpendiculaire au plan P du tablier 1.Particularly advantageously, the latch or strikes 21 are designed in the manner of a cam and comprise a ramp 24, as visible on the figure 3 , adapted, under the effect of a longitudinal displacement printed to the transmission means 6, to confer, through its cooperation with a bolt 20, a displacement at said link 14 perpendicular component to the plane P of the deck 1.

Ainsi, sous l'effet de cette coopération entre le ou les pênes 20 et la ou les gâches 21, sous forme de rampes 24, l'axe d'articulation 18 de la biellette 14 sur la lame orientable 2A, plus exactement le point d'articulation médian P2 de la genouillère, est repoussé mécaniquement dans une direction de manière à s'écarter du plan P du dispositif de tablier 1, autrement dit le plan dans lequel se situent, sensiblement, les points d'articulation bas P1 et haut P3 de cette genouillère.Thus, under the effect of this cooperation between the bolt or bolts 20 and the latches 21, in the form of ramps 24, the hinge axis 18 of the link 14 on the steerable blade 2A, more precisely the point d median articulation P2 of the toggle joint, is mechanically pushed in a direction so as to deviate from the plane P of the deck device 1, in other words the plane in which are substantially the low points of articulation P1 and P3 high from this knee pad.

Il s'ensuit qu'au moment de la commande d'ouverture des lames orientables 2A, l'effet de came produit par la rampe 24 de la gâche 21 facilite le début de la commande de pivotement des lames orientables 2A dans cette direction d'ouverture. Au-delà de la course C, le ou les pênes 20 quittant leurs gâches 21, la commande de déploiement des lames orientables 2A intervient sans grand effort de résistance en raison du bras de levier alors existant entre l'axe d'articulation 18 de la biellette 14 sur la lame orientable 2A et le plan P. La biellette 14 peut alors librement basculer pour repousser une lame orientable 2A dans une position d'ouverture ou d'aération totale.It follows that at the time of the opening control of the steerable blades 2A, the cam effect produced by the ramp 24 of the keeper 21 facilitates the start of the pivoting control of the steerable blades 2A in this direction of opening. Beyond the stroke C, the bolt or 20 leaving their latches 21, the deployment command of the steerable blades 2A occurs without great resistance effort because of the lever arm then existing between the axis of articulation 18 of the rod 14 on the swiveling blade 2A and the plane P. The link 14 can then freely rock to push a swivelable blade 2A in a fully open or vented position.

Contrairement, lors de la fermeture, les moyens de transmission 6 exécutent une première course ayant pour conséquence le basculement de ces lames orientables 2 en direction de la fermeture, donc du plan P. En continuant à conférer aux moyens de transmission 6 une course complémentaire, en l'occurrence par rapport aux moyens d'entraînement 10, il s'ensuit l'engagement du ou des pênes 20 dans leurs gâches 21 et leur progression le long de la rampe 24, action ayant pour conséquence de tirer davantage la biellette 14 en direction de ce plan P du dispositif de tablier 1, se traduisant par une parfaite fermeture et le verrouillage des lames orientables 2A.In contrast, when closing, the transmission means 6 execute a first stroke resulting in the tilting of these orientable blades 2 in the direction of the closure, thus the plane P. Continuing to give the transmission means 6 a complementary stroke, in this case with respect to the drive means 10, it follows the engagement of the bolt or bolts 20 in their latches 21 and their progression along the ramp 24, action resulting in further pulling the link 14 in direction of this plane P of the apron device 1, resulting in a perfect closure and locking of the steerable blades 2A.

Il est évident que convenablement plaquées, en bordure inférieure 5, en recouvrement sur une lame fixe 2B suivante, les lames orientables ainsi fermées procurent une parfaite étanchéité du tablier 1. Les lames orientables 2A, verrouillées, ne peuvent battre au vent et, surtout, elles ne peuvent être aisément écartées du plan P du dispositif de tablier 1.It is obvious that suitably plated, at the bottom edge 5, overlapping on a fixed blade 2B, the swiveling blades thus closed provide a perfect seal of the deck 1. The adjustable blades 2A, locked, can not beat in the wind and, above all, they can not be easily separated from the plane P of the deck device 1.

On observera que sous l'effet de la came que définit la rampe 24 d'une gâche 21, le point d'articulation médian P2 peut être repoussé au-delà du plan P passant par les deux points d'articulation extrêmes de la genouillère, soit du côté opposé à la direction dans laquelle intervient le basculement les lames orientables 2A. Cela est notamment rendu possible au travers d'une mobilité relative de l'axe d'articulation 18 dans une direction correspondant au sens de déploiement du tablier 1, ceci par rapport à la biellette 14 et la lame orientable 2A que cet axe 18 relie. Comme visible dans les figures 2 et 5, la biellette 14, comporte, à son extrémité coopérant avec la lame orientable 2A, des oeillets oblongs autorisant cette mobilité relative. De ce fait l'amplitude de pivotement de la biellette n'est pas strictement dépendant du celle du déplacement linéaire des moyens de transmission 6 par rapport aux moyens d'entrainement 10.It will be observed that under the effect of the cam defined by the ramp 24 of a striker 21, the central articulation point P2 can be pushed beyond the plane P passing through the two extreme hinge points of the toggle joint, either on the side opposite to the direction in which the tilting occurs the orientable blades 2A. This is made possible in particular by a relative mobility of the hinge axis 18 in a direction corresponding to the direction of deployment of the deck 1, this with respect to the rod 14 and the swiveling blade 2A that this axis 18 connects. As visible in figures 2 and 5 , the link 14 comprises, at its end cooperating with the orientable blade 2A, oblong eyelets allowing this relative mobility. As a result, the pivoting amplitude of the link is not strictly dependent on that of the linear displacement of the transmission means 6 with respect to the drive means 10.

En faisant ainsi dépasser le point d'articulation médian P2 de la genouillère une compression imprimée sur le tablier, correspondant à une tentative de soulever ce dernier depuis l'extérieur d'une habitation, a pour conséquence une augmentation de la force d'application des lames orientables 2A les lames fixes 2B, donc une rigidification du tablier 1 procurant une sécurité améliorée.By thus passing beyond the median pivot point P2 of the toggle joint a compression printed on the apron, corresponding to an attempt to lift the latter from the outside of a house, results in an increase in the application force of the adjustable blades 2A the fixed blades 2B, so a stiffening of the deck 1 providing improved security.
