Description

La présente invention concerne le domaine des structures déployables, et plus particulièrement mais non limitativement, le domaine des fermetures pour bâtiments domestiques ou industriels, et elle a pour objet un dispositif de fermeture comportant une structure composée d'une succession de tronçons articulés deux à deux, déployable entre deux plans parallèles, et repliable en accordéon.The present invention relates to the field of deployable structures, and more particularly but not limited to, the field of closures for domestic or industrial buildings, and its subject is a closure device comprising a structure composed of a succession of sections articulated in pairs , deployable between two parallel planes, and foldable like an accordion.

Une telle structure peut trouver, non limitativement, des applications dans le domaine des volets roulants, des grilles de sécurité, que ce soit verticalement ou horizontalement.Such a structure can find, without limitation, applications in the field of rolling shutters and security grilles, whether vertically or horizontally.

La plupart des structures déployables, sont repliées, enroulées sur un tambour. Un tel système présente des limites, car les lames qui composent la structure doivent être de faible largeur, en effet, à partir d'une certaine dimension l'enroulement nécessite un tambour de grand diamètre, ce qui peut nuire à des objectifs de réduction d'encombrement. Or, une faible largeur des lames est synonyme de souplesse et de moindre rigidité, ce qui peut être rédhibitoire lorsque la structure déployable est destinée à être utilisée dans un but de sécurisation d'un lieu.Most deployable structures are folded, rolled up on a drum. Such a system has limits, because the blades which make up the structure must be of small width, in fact, from a certain dimension the winding requires a drum of large diameter, which can harm the objectives of reduction of clutter. However, a small width of the blades is synonymous with flexibility and less rigidity, which can be prohibitive when the deployable structure is intended to be used for the purpose of securing a place.

Par conséquent, l'utilisation de lames de grande largeur nécessite un stockage à plat, dans le prolongement les unes des autres, ce qui bien évidemment est encombrant.Consequently, the use of very wide blades requires storage flat, in line with each other, which is obviously cumbersome.

On connaît toutefois des structures déployables qui, associées à un système de guidage particulier, permettent le repliement des lames en accordéon, réduisant ainsi les dimensions de stockage. L'inconvénient de ces structures déployables consiste souvent en des défauts de fiabilité, et notamment de coincement que ce soit à l'ouverture ou à la fermeture.However, deployable structures are known which, associated with a particular guiding system, allow the blades to be folded into an accordion, thus reducing the storage dimensions. The disadvantage of these deployable structures often consists of reliability defects, and in particular jamming whether when opening or closing.

Le document EP 0 756 062 décrit telle grille, constituée de tronçons articulés deux-à-deux, dont les bords latéraux sont équipés de galets montés coulissants dans des coulisses bordant l'ouverture à fermer. La grille est entraînée en ouverture et en fermeture par des systèmes à chaîne ou courroie disposés dans lesdites coulisses. Lors de l'opération d'ouverture, les différents tronçons se replient les uns contre les autres en accordéon, ce qui est rendu possible au travers d'un système de guidage et d'aiguillage, où lesdits galets sont en alternance de diamètres et de longueurs différents, pour coopérer avec lesdites coulisses latérales conformées pour présenter deux largeurs différentes à des profondeurs différentes correspondant aux profils desdits galets, ces coulisses se ramifiant dans la zone de stockage en deux branches parallèles chacune adaptée pour accueillir un seul type de galet.The document EP 0 756 062 describes such a grid, consisting of sections articulated two by two, the lateral edges of which are equipped with rollers mounted sliding in slides bordering the opening to be closed. The gate is driven to open and closing by chain or belt systems arranged in said slides. During the opening operation, the different sections fold against each other in an accordion, which is made possible through a guiding and switching system, where said rollers are alternating in diameter and width. different lengths, to cooperate with said lateral slides shaped to present two different widths at different depths corresponding to the profiles of said rollers, these slides branching in the storage zone into two parallel branches each adapted to accommodate a single type of roller.

L'inconvénient de cette structure consiste, comme les autres structures de ce type, en des risques de coincement. En effet, quand par exemple la zone de stockage est pleine et que doit être amorcée une phase de déploiement, les moyens d'actionnement exercent une traction vers le bas, ou libèrent des moyens de retenue, c'est l'ensemble des lames repliées qui est entraîné et qui doit se déplacer horizontalement dans les deux branches de chacune des coulisses, avec un risque évident d'arcboutement conduisant à un coincement.The disadvantage of this structure consists, like other structures of this type, in the risk of getting stuck. Indeed, when for example the storage zone is full and a deployment phase must be initiated, the actuation means exert a downward pull, or release the retaining means, this is all of the folded blades which is driven and which must move horizontally in the two branches of each of the slides, with an obvious risk of bracing leading to jamming.

Le document WO 2012/120483 concerne également une grille constituée de tronçons articulés deux-à-deux, comprenant une zone de stockage après ouverture, où lesdits tronçons se replient les uns contre les autres en accordéon. A cet effet, chacun desdits tronçons comporte à chacune de ses extrémités deux galets destinés à coopérer en coulissement avec un rail, lequel se ramifie en deux branches dans la zone de stockage. L'aiguillage et le guidage sont réalisés par l'intermédiaire des moyens d'entraînement qui indexent chacun des galets dans l'une ou l'autre desdites branches.The document WO 2012/120483 also concerns a grid made up of sections articulated two by two, comprising a storage zone after opening, where said sections fold against each other in an accordion. For this purpose, each of said sections comprises at each of its ends two rollers intended to cooperate in sliding with a rail, which branches into two branches in the storage zone. The switching and guiding are carried out via drive means which index each of the rollers in one or the other of said branches.

La structure de ce document présente le même inconvénient, il est même amplifié lorsque le stockage des lames est réalisé verticalement. En effet, lors du déploiement après stockage les moyens d'entraînement doivent soulever l'ensemble des lames repliées pour le faire coulisser dans les deux branches de chacun des rails, le poids des lames accroît les risques d'arcboutement dans lesdites branches. De même lors du repliement, les lames sont repliées les unes contre les autres pour former un ensemble suspendu aux moyens d'entraînement.The structure of this document has the same disadvantage, it is even amplified when the slides are stored vertically. Indeed, during deployment after storage the drive means must lift all of the folded blades to make them slide in the two branches of each of the rails, the weight of the blades increases the risks bracing in said branches. Likewise during folding, the blades are folded against each other to form an assembly suspended from the drive means.

Outre les risques de coincement, ces structures déployables présentent des inconvénients d'encombrement, notamment dus à la conception des moyens d'entraînement.In addition to the risk of entrapment, these deployable structures present disadvantages of bulk, in particular due to the design of the drive means.

On connaît également par le document US 4 303 117 , un dispositif de fermeture qui comporte une structure composée d'une succession de tronçons articulés deux à deux, déployable entre les deux plans parallèles d'un dormant, et repliable en accordéon dans une zone de stockage, associée à des moyens moteurs aptes à l'entraîner en translation dans le sens du repliement et/ou du déploiement, chacun desdits tronçons étant associé à deux moyens d'indexage, qui coopèrent en coulissement avec un chemin de guidage, lequel se ramifie en deux branches secondaires au niveau de ladite zone de stockage, dans une configuration permettant qu'en déplacement en direction de ladite zone de stockage, en association avec des moyens annexes d'aiguillage, un moyen d'indexage emprunte une branche secondaire différente de celle empruntée par le moyen d'indexage qui le suit ou qui le précède. Dans ce dispositif lesdits moyens d'indexage consistent en des galets, tandis que l'aiguillage est réalisé au travers de rouleaux à degrés qui doublent un galet sur deux, et qui sont destinés à coopérer avec un plan incliné disposé au niveau de la ramification.We also know from the document US 4,303,117 , a closing device which comprises a structure composed of a succession of sections articulated two by two, deployable between the two parallel planes of a frame, and foldable like an accordion in a storage zone, associated with motor means capable of 'drive in translation in the direction of folding and/or deployment, each of said sections being associated with two indexing means, which cooperate in sliding with a guide path, which branches into two secondary branches at the level of said zone of storage, in a configuration allowing that when moving towards said storage zone, in association with additional switching means, an indexing means takes a secondary branch different from that taken by the indexing means which follows it or which precedes it. In this device, said indexing means consist of rollers, while the switching is carried out through step rollers which double every other roller, and which are intended to cooperate with an inclined plane arranged at the level of the branch.

Du fait de sa relative complexité, notamment le nombre de pièces différentes mises en œuvre pour réaliser l'aiguillage, ce dispositif présente des risques de défaut de fiabilité dans le temps.Due to its relative complexity, in particular the number of different parts used to make the switch, this device presents risks of unreliability over time.

Le document EP1686224 A2 décrit un dispositif de fermeture comportant une structure composée d'une succession de tronçons articulés deux à deux, déployable entre les deux plans parallèles dudit dormant, et repliable en accordéon dans une zone de stockage, associée à des moyens moteurs aptes à l'entraîner en translation dans le sens du repliement et/ou du déploiement, chacun desdits tronçons étant associé à deux moyens d'indexage, qui coopèrent en coulissement avec un chemin de guidage, lequel se ramifie en deux branches secondaires au niveau de ladite zone de stockage, dans une configuration permettant qu'en déplacement en direction de ladite zone de stockage, en association avec des moyens annexes d'aiguillage, un desdits moyens d'indexage emprunte une branche secondaire différente de celle empruntée par le moyen d'indexage qui le suit ou qui le précède, où lesdites branches secondaires et la zone de stockage sont disposées à la verticale du chemin de guidage en sorte que la masse desdits tronçons empilés assure le maintien desdits tronçons empilés les uns sur les autres ; et ou lesdits moyens d'aiguillage consistent en une came de distribution, mobile en pivotement autour d'un axe horizontal parallèle au plan de la structure, conçue apte à prendre, au gré de son pivotement, des positions aiguillant lesdits moyens d'indexage en alternance vers l'une ou l'autre desdites deux branches secondaires, et en sorte que le déplacement en pivotement, pour prendre une position aiguillant un moyen d'indexage vers une branche secondaire, soit généré par le déplacement dans l'autre branche secondaire du moyen d'indexage qui le précède dans ledit chemin de guidage.The document EP1686224 A2 describes a closing device comprising a structure composed of a succession of sections articulated two by two, deployable between the two parallel planes of said frame, and foldable like an accordion in a storage zone, associated with motor means capable of driving it in translation in the direction of folding and/or deployment, each of said sections being associated with two indexing means, which cooperate in sliding with a guide path, which branches into two secondary branches at said storage zone, in a configuration allowing that when moving towards said storage zone, in association with additional switching means, one of said indexing means takes a secondary branch different from that taken by the indexing means which follows it or which precedes it, where said secondary branches and the storage zone are arranged vertically of the guide path so that the mass of said stacked sections ensures the maintenance of said sections stacked on top of each other; and or said switching means consist of a distribution cam, movable in pivoting around a horizontal axis parallel to the plane of the structure, designed capable of taking, as it pivots, positions directing said indexing means in alternation towards one or the other of said two secondary branches, and such that the pivoting movement, to take a position directing an indexing means towards a secondary branch, is generated by the movement in the other secondary branch of the indexing means which precede it in said guide path.

Ne faisant pas partie de l'invention, il existe un dispositif de fermeture qui comporte une structure composée d'une succession de tronçons articulés deux à deux, déployable entre les deux plans parallèles d'un dormant, et repliable en accordéon dans une zone de stockage, associée à des moyens moteurs aptes à l'entraîner en translation dans le sens du repliement et/ou du déploiement, chacun desdits tronçons étant associé à deux moyens d'indexage, qui coopèrent en coulissement avec un chemin de guidage, lequel se ramifie en deux branches secondaires au niveau de ladite zone de stockage, dans une configuration permettant qu'en déplacement en direction de ladite zone de stockage, en association avec des moyens annexes d'aiguillage, un moyen d'indexage emprunte une branche secondaire différente de celle empruntée par le moyen d'indexage qui le suit ou qui le précède, où lesdites branches secondaires et la zone de stockage sont disposées à la verticale du chemin de guidage en sorte que la masse desdits tronçons empilés assure le maintien desdits tronçons empilés les uns sur les autres ; et en ce que les moyens annexes d'aiguillage comprennent d'une part un premier élément de butée localisé sur le dormant au niveau du chemin de guidage et à proximité de la ramification, et d'autre part un second élément de butée disposé sur un tronçon sur deux, localisé entre les deux moyens d'indexage de ce tronçon, et conçu apte à coopérer en appui avec ledit premier élément de butée de manière à provoquer le basculement dudit tronçon et ainsi l'engagement du moyen d'indexage le plus proche de ladite ramification dans la branche secondaire qui lui est dédiée.Not forming part of the invention, there is a closing device which comprises a structure composed of a succession of sections articulated two by two, deployable between the two parallel planes of a frame, and foldable like an accordion in a zone of storage, associated with motor means capable of driving it in translation in the direction of folding and/or deployment, each of said sections being associated with two indexing means, which cooperate in sliding with a guide path, which branches in two secondary branches at the level of said storage zone, in a configuration allowing that when moving towards said storage zone, in association with additional switching means, an indexing means takes a secondary branch different from that taken by the indexing means which follows or precedes it, where said secondary branches and the storage zone are arranged vertically of the guide path so that the mass of said stacked sections ensures the maintenance of said sections stacked on each other others ; and in that the additional switching means comprise on the one hand a first stop element located on the frame at the level of the guide path and close to the branch, and on the other hand a second stop element arranged on a section in two, located between the two indexing means of this section, and designed capable of cooperating in support with said first stop element so as to cause the tilting of said section and thus the engagement of the nearest indexing means of said branch in the secondary branch dedicated to it.

Selon une caractéristique additionnelle du dispositif de fermeture selon l'invention, les moyens moteurs aptes à l'entraînement en translation dans le sens du repliement et/ou du déploiement, comprennent, sur au moins un côté de la structure, d'une part une crémaillère constituée de l'aboutement de portions de crémaillère, chacune correspondant à un tronçon constituant ladite structure, et d'autre part un pignon entraîné, engrené sur ladite crémaillère.According to an additional characteristic of the closing device according to the invention, the motor means capable of driving in translation in the direction of folding and/or deployment, comprise, on at least one side of the structure, on the one hand a rack made up of the abutment rack portions, each corresponding to a section constituting said structure, and on the other hand a driven pinion, meshed with said rack.

Selon une autre caractéristique additionnelle du dispositif de fermeture selon l'invention, une portion de crémaillère sur deux comporte à une extrémité, celle opposée à celle dirigée vers la zone de stockage, une déformation apte à coopérer avec le pignon d'entraînement en sorte que l'engrènement sur celui-ci provoque le basculement de ladite portion pour réaliser l'aiguillage.According to another additional characteristic of the closure device according to the invention, one rack portion out of two comprises at one end, the one opposite that directed towards the storage zone, a deformation capable of cooperating with the drive pinion so that the meshing thereon causes said portion to tilt to create the switch.

Selon un autre mode de réalisation particulier du dispositif de fermeture ne faisant pas partie de l'invention, chacun des tronçons comporte, en partie ou en totalité de son bord longitudinal disposé du côté de la zone de stockage lorsque ledit tronçon est engagé dans le chemin de guidage, une extension se projetant au-delà de l'axe du moyen d'indexage proche dudit bord, tandis que le dormant comporte un élément de soutien disposé en bordure de chacune des branches secondaires, et extérieurement auxdites branches, lesdits éléments de soutien ainsi que lesdites extensions étant conformés, disposés et dimensionnés, en sorte que lorsque tronçon bascule pour prendre sa position de stockage, son extension se place au-delà de l'élément de soutien en regard pour prendre appui dessus.According to another particular embodiment of the closure device not forming part of the invention, each of the sections comprises, in part or in whole, its longitudinal edge disposed on the side of the storage zone when said section is engaged in the path guide, an extension projecting beyond the axis of the indexing means close to said edge, while the frame comprises a support element disposed at the edge of each of the secondary branches, and externally to said branches, said support elements as well as said extensions being shaped, arranged and dimensioned, so that when the section tilts to take its storage position, its extension is placed beyond the supporting element opposite to rest on it.

En référence aux figures 1 et 2, on peut voir une représentation, très schématique, d'un dispositif de fermeture selon l'invention, lequel comprend une structure 1 composée d'une succession de tronçons 10 articulés deux à deux, au moyen d'axes 11, déployable comme cela est représenté sur la figure 1, et repliable en accordéon dans une zone de stockage S, comme cela est représenté sur la figure 2.With reference to figures 1 and 2 , we can see a very schematic representation of a closing device according to the invention, which comprises a structure 1 composed of a succession of sections 10 articulated two by two, by means of axes 11, deployable as shown in the figure 1 , and foldable like an accordion in a storage area S, as shown on the figure 2 .

Le dispositif de fermeture selon l'invention peut trouver de nombreuses applications, la structure 1 peut notamment, mais non limitativement, consistée en un volet ou une grille.The closure device according to the invention can find numerous applications, the structure 1 can in particular, but not limited to, consist of a shutter or a grid.

La structure 1 est prévue pour être repliée et déployée en les deux plans parallèles d'un dormant, dont un 2 est visible sur les figures 1 et 2, sachant que l'autre en vis à vis est symétrique.The structure 1 is intended to be folded and deployed in the two parallel planes of a frame, of which a 2 is visible on the figures 1 and 2 , knowing that the other opposite is symmetrical.

Le plan 2 comporte un chemin de guidage 20, se présentant sous la forme d'une gorge en U, dans laquelle sont insérés des moyens d'indexage 12, de préférence des galets, que comportent les tronçons 10 à chacun de leur bord extrême 13. Chacun des tronçons 10 comporte un moyen d'indexage 12, proche d'un axe 11, seul le tronçon 10 extrême en comporte deux, un à chaque extrémité.The plane 2 comprises a guide path 20, in the form of a U-shaped groove, in which indexing means 12 are inserted, preferably rollers, which the sections 10 have at each of their extreme edges 13 Each of the sections 10 includes an indexing means 12, close to an axis 11, only the extreme section 10 has two, one at each end.

On notera, comme cela apparaît dans d'autres modes de réalisation, que les moyens d'indexage 12 peuvent être coaxiaux aux axes 11.It will be noted, as appears in other embodiments, that the indexing means 12 can be coaxial with the axes 11.

Le chemin de guidage 20 se ramifie en deux branches secondaires 21 et 22, au niveau de la zone de stockage S.The guide path 20 branches into two secondary branches 21 and 22, at the level of the storage zone S.

Lors du repliement de la structure 1 dans la zone de stockage S, les moyens d'indexage 12 successifs s'engagent, alternativement, dans les branches secondaires 21 et 22 du chemin de guidage 20, en sorte que du fait également des axes 11, les tronçons viennent se placer les uns contre les autres, en accordéon.When folding the structure 1 in the storage zone S, the successive indexing means 12 engage, alternately, in the secondary branches 21 and 22 of the guide path 20, so that also due to the axes 11, the sections are placed against each other, like an accordion.

Selon l'invention les branches secondaires 21 et 22 sont disposées à la verticale du chemin de guidage 20, en sorte que lors du repliement dans la zone de stockage S, les tronçons 10, qui sont entraînés du bas vers le haut par des moyens moteurs, non représentés, s'empilent par le dessous, en sorte que le poids croissant de l'empilement de tronçons 10 assure une poussée antagoniste à celle d'entraînement, qui permet d'assurer le bon positionnement des tronçons 10 et donc d'éviter les problèmes de coincement par arcboutement, des dispositifs de fermeture analogues connus.According to the invention the secondary branches 21 and 22 are arranged vertically of the guide path 20, so that when folding into the storage zone S, the sections 10, which are driven from the bottom upwards by motor means , not shown, stack from below, so that the increasing weight of the stack of sections 10 ensures a thrust opposing that of the drive, which makes it possible to ensure the correct positioning of the sections 10 and therefore to avoid the problems of jamming by buttressing, of known similar closing devices.

La difficulté de fonctionnement d'un tel mécanisme réside encore dans l'aiguillage des moyens d'indexage 12 dans l'une ou l'autre des deux branches secondaires du chemin de guidage.The difficulty in operating such a mechanism still lies in the routing of the indexing means 12 in one or the other of the two secondary branches of the guide path.

Dans le mode de réalisation simplifié représenté sur les figures 1 et 2, il peut être envisagé d'associer les axes 11 à des ressorts aptes à amorcer le repliement d'un tronçon 10 sur le suivant au niveau de la ramification pour engager le moyen d'indexage dans la bonne branche. Une telle solution nécessite toutefois une grande fiabilité des moyens ressorts.In the simplified embodiment shown on the figures 1 and 2 , it can be envisaged to associate the axes 11 with springs capable of initiating the folding of one section 10 onto the next at the level of the branch to engage the indexing means in the correct branch. However, such a solution requires great reliability of the spring means.

En référence aux figures 3 et 4, on peut voir la partie aiguillage d'un mode de réalisation particulier du dispositif de fermeture ne faisant pas partie de l'invention. Comme cela est visible sur la figure 3, les deux branches secondaires 21 et 22 sont symétriques par rapport à l'axe du chemin de guidage 20, tandis que n'est représenté que le bord 13 d'un tronçon 10, lequel est équipé de deux moyens d'indexage 12, en l'occurrence deux galets supérieur 120 et inférieur 121, chacun coaxial à l'axe d'articulation les tronçons voisins.With reference to figures 3 and 4 , we can see the switching part of a particular embodiment of the closing device not forming part of the invention. As can be seen on the Figure 3 , the two secondary branches 21 and 22 are symmetrical with respect to the axis of the guide path 20, while only the edge 13 of a section 10 is shown, which is equipped with two indexing means 12, in the occurrence of two rollers upper 120 and lower 121, each coaxial with the axis of articulation of the neighboring sections.

Sur la figure 4 on peut voir que l'équilibre du bord 13 impose une force F pour contrer la poussée latérale L de la branche 22 sur le galet supérieur 120. Cette force F existe si le galet inférieur 121 est encore engagé dans le chemin de guidage 20. Lorsque le galet 121 sort du chemin de guidage 20 la force F n'existe plus, ce qui provoque, du fait du poids P1 du tronçon 10, du poids P2 des tronçons 10 déjà stockés si il y en a, et de la force de manoeuvrement M de la structure 1, le mouvement du galet 121 vers la branche 21 et son engagement.On the Figure 4 we can see that the balance of the edge 13 imposes a force F to counter the lateral thrust L of the branch 22 on the upper roller 120. This force F exists if the lower roller 121 is still engaged in the guide path 20. When the roller 121 leaves the guide path 20 the force F no longer exists, which causes, due to the weight P1 of the section 10, the weight P2 of the sections 10 already stored if there are any, and the operating force M of structure 1, the movement of roller 121 towards branch 21 and its engagement.

En référence maintenant aux figures 5 et 6a, 6b, 6c et 6d, on peut voir un autre mode de réalisation, où les branches 20 et 21 ne sont pas nécessairement symétriques.Referring now to figures 5 and 6a, 6b, 6c and 6d , we can see another embodiment, where the branches 20 and 21 are not necessarily symmetrical.

Là-encore, n'est représenté que le bord 13 d'un tronçon 10, équipé de deux moyens d'indexage 12, en l'occurrence deux galets, chacun coaxial à l'axe d'articulation les tronçons voisins.Here again, only the edge 13 of a section 10 is shown, equipped with two indexing means 12, in this case two rollers, each coaxial with the axis of articulation of neighboring sections.

On peut constater que le bord 13 comporte à proximité du galet inférieur 121, un bossage 14, tandis que le dormant 2 comporte en bordure du chemin de guidage 20 et à proximité de la ramification en deux branches 21 et 22, une butée 23, qui est dimensionnée et positionnée pour interagir avec le bossage 14 comme cela apparaît sur les figures 6a, 6b, 6c et 6d.It can be seen that the edge 13 comprises, near the lower roller 121, a boss 14, while the frame 2 comprises at the edge of the guide path 20 and near the branching into two branches 21 and 22, a stop 23, which is dimensioned and positioned to interact with the boss 14 as appears on the figures 6a, 6b, 6c and 6d .

Lorsque le galet supérieur 120 s'engage au niveau de la ramification, le bossage 14 rencontre la butée 23 qui repousse le tronçon 10, et puisque le galet supérieur 120 est en regard de l'amorce de la branche secondaire 21, il s'y engage.When the upper roller 120 engages at the level of the branch, the boss 14 meets the stop 23 which pushes back the section 10, and since the upper roller 120 is opposite the start of the secondary branch 21, it is there engaged.

Bien entendu, le bord 13 du tronçon 10 qui suit immédiatement, ne comporte pas de bossage 14, en sorte qu'il n'est pas dévié et le galet inférieur 121 s'engage dans la branche secondaire 22.Of course, the edge 13 of the section 10 which immediately follows does not have a boss 14, so that it is not deflected and the lower roller 121 engages in the secondary branch 22.

On notera toutefois, en référence à la figure 7, que le tronçon 10 suivant qui y est représenté et qui par conséquent comporte un galet supérieur 121, présente préférentiellement un bossage 15 qui fait saillie entre les galets 12 et qui est donc apte à être engagé dans le chemin de guidage 20, en sorte qu'il n'est pas possible au galet 121, de s'engager dans la branche 21.It should be noted, however, with reference to the Figure 7 , that the following section 10 which is shown there and which therefore comprises an upper roller 121, preferably has a boss 15 which projects between the rollers 12 and which is therefore capable of being engaged in the guide path 20, so that It is not possible at roller 121 to engage in branch 21.

En référence maintenant aux figures 8a, 8b, 8c, 8d, 8e et 8f, on peut voir une variante du mode de réalisation précédent, en ce sens que l'on retrouve le bossage 14 sur le bord 13 d'un tronçon 10 sur deux, ainsi que la butée 23, permettant d'aiguiller les galets 120 vers la branche secondaire 21.Referring now to figures 8a, 8b, 8c, 8d, 8e and 8f , we can see a variant of the previous embodiment, in the sense that we find the boss 14 on the edge 13 of one section 10 out of two, as well as the stop 23, making it possible to direct the rollers 120 towards the secondary branch 21.

Dans ce mode de réalisation, les bords 13 des tronçons 10 aboutés reconstituent une crémaillère 4 en étant constitués de portions de crémaillère 40 et 41, et sur laquelle s'engrène un pignon motorisé 24, constituant les moyens d'entraînement.In this embodiment, the edges 13 of the butted sections 10 reconstitute a rack 4 by being made up of rack portions 40 and 41, and on which a motorized pinion 24 meshes, constituting the drive means.

On notera que la partie dentée des portions de crémaillère 40, correspondant aux tronçons 10 comportant le bossage 23, présente, au droit de ce bossage 23 une partie dentée 42 de forme concave, destinée à maintenir constant l'engrènement du pignon 24 sans empêcher le basculement d'aiguillage.It will be noted that the toothed part of the rack portions 40, corresponding to the sections 10 comprising the boss 23, presents, to the right of this boss 23, a toothed part 42 of concave shape, intended to maintain the meshing of the pinion 24 constant without preventing the switching of the switch.

En référence maintenant aux figures 9, 10a et 10b, on peut voir que selon une variante il est possible de s'affranchir de la coopération d'un bossage avec une butée.Referring now to figures 9, 10a and 10b , we can see that according to a variant it is possible to get rid of the cooperation of a boss with a stop.

Ainsi, le bord de la structure 1, et de préférence chacun des deux bords, consiste également en une crémaillère 4 sur laquelle s'engrène un pignon 24, et constituée de l'aboutement de portions de crémaillère.Thus, the edge of structure 1, and preferably each of the two edges, also consists of a rack 4 on which a pinion 24 meshes, and constituted by the abutment of rack portions.

Sur ces figures on peut voir une portion 43 de crémaillère qui comporte à chacune de ses extrémités un alésage 44 et 45, chacun destiné à recevoir l'arbre d'un galet, respectivement inférieur et supérieur, non représentés.In these figures we can see a rack portion 43 which has at each of its ends a bore 44 and 45, each intended to receive the shaft of a roller, respectively lower and upper, not shown.

L'extrémité proche de l'alésage 44 comporte à partir de la zone comportant cet alésage 44, une extension 46 qui fait un angle par rapport à la direction générale de la portion de crémaillère 43, pour former un talon.The end close to the bore 44 comprises, from the zone comprising this bore 44, an extension 46 which makes an angle with respect to the general direction of the rack portion 43, to form a heel.

Comme cela est visible sur la figure 10b, lors de l'entraînement de la crémaillère 4 par le pignon 24, le passage sur le talon 46 provoque le basculement de la portion 43 autour de l'axe du galet inférieur, ce qui permet de réaliser l'aiguillage.As can be seen on the figure 10b , when the rack 4 is driven by the pinion 24, the passage over the heel 46 causes the portion 43 to tilt around the axis of the lower roller, which makes it possible to produce the switch.

En référence maintenant aux figures 11a, 11b et 11c, on peut voir un dispositif de fermeture selon l'invention comportant une particularité, adaptable aux autres modes de réalisation décrits précédemment.Referring now to figures 11a, 11b and 11c , we can see a closing device according to the invention comprising a particularity, adaptable to the other embodiments described above.

On retrouve sur ces figures le chemin de guidage 20 ramifié en deux branches secondaires 21 et 22, ainsi qu'un tronçon 10 et ses deux moyens d'indexage ou galets supérieur 120 et inférieur 121, sachant que les autres tronçons 10 de la structure 1 ne sont pas représentés.We find in these figures the guide path 20 branched into two secondary branches 21 and 22, as well as a section 10 and its two indexing means or rollers upper 120 and lower 121, knowing that the other sections 10 of the structure 1 are not represented.

Dans ce mode de réalisation, le dormant 2 comporte extérieurement à la branche 21, celle destinée à recevoir le premier moyen d'indexage ou galet du premier tronçon 10, en l'occurrence le galet 120, un élément de soutien 25, tandis que le tronçon 10 comporte, du côté du galet 120, une extension 16 se projetant au-delà de l'axe 11.In this embodiment, the frame 2 comprises externally to the branch 21, that intended to receive the first indexing means or roller of the first section 10, in this case the roller 120, a support element 25, while the section 10 comprises, on the side of the roller 120, an extension 16 projecting beyond the axis 11.

On peut voir précisément sur la figure 11b, le galet 120 est largement engagé dans la branche 21, tandis que le tronçon 10 est encore dans une position sensiblement verticale, en sorte que son extension 16 demeure au droit de la branche 21 et esquive ainsi l'élément de soutien 25.We can see precisely on the figure 11b , the roller 120 is largely engaged in the branch 21, while the section 10 is still in a substantially vertical position, so that its extension 16 remains in line with the branch 21 and thus avoids the support element 25.

Sur la figure 11C, le tronçon 10 amorce son positionnement à l'horizontale, en sorte que, lors de son basculement sous l'effet de la poussée du tronçon 10 suivant non représenté, son pivotement autour de l'axe 11 du galet 120 provoque le déport de l'extension 16 vers l'extérieur, au-dessus de l'élément de soutien 25, jusqu'à permettre une prise d'appui sur celui-ci.On the Figure 11C , the section 10 begins its horizontal positioning, so that, during its tilting under the effect of the thrust of the next section 10 not shown, its pivoting around the axis 11 of the roller 120 causes the offset of the extension 16 outwards, above the support element 25, until it allows support to be placed on it.

Après, le prolongement de la poussée finit de mettre en place tronçon 10, en sorte qu'il s'immobilise à l'horizontale au travers de la coopération du galet 121 avec la branche 22, sachant qu'une partie du poids est supportée par l'élément de soutien 25.Afterwards, the extension of the thrust finishes putting section 10 in place, so that it comes to rest horizontally through the cooperation of the roller 121 with the branch 22, knowing that part of the weight is supported by the support element 25.

Bien entendu, le troisième tronçon 10 est conforme au premier, c'est-à-dire qu'il comporte une extension 16 qui est destinée à prendre appui sur l'élément de soutien 25, en remplacement de l'extension 16 du premier tronçon 10 et ainsi de suite.Of course, the third section 10 conforms to the first, that is to say it includes an extension 16 which is intended to bear on the support element 25, replacing the extension 16 of the first section 10 and so on.

Cette configuration, autorise une meilleure gestion des efforts dans le mécanisme d'entraînement, l'utilisation du dormant pour supporter une partie du poids de la structure permet de limiter la force nécessaire au mouvement.This configuration allows better management of the efforts in the drive mechanism, the use of the frame to support part of the weight of the structure makes it possible to limit the force necessary for the movement.

Il est à noter que l'extension 16 peut être constituée de plusieurs extension réparties longitudinalement sur le tronçon 10, ou bien d'une seule partie qui s'entend tout le long de ce dernier, tandis que l'élément de soutien consiste, de manière adéquate, en un appui tel qu'un épaulement ou rebord que comporte le dormant 2.It should be noted that the extension 16 can consist of several extensions distributed longitudinally over the section 10, or of a single part which extends all along the latter, while the support element consists of adequately, in a support such as a shoulder or rim that the frame 2 includes.

En référence maintenant à la figure 12 on peut voir que selon une variante, le dormant 2 comporte en plus de l'élément de soutien 25, un élément de soutien 26 disposé extérieurement à la branche 22, tandis que chacun des tronçons 10 comporte à son extrémité dirigée vers la zone de stockage S, une extension 16.Referring now to the Figure 12 it can be seen that according to a variant, the frame 2 comprises in addition to the support element 25, a support element 26 arranged externally at the branch 22, while each of the sections 10 has at its end directed towards the storage zone S, an extension 16.

On comprendra que chacun des tronçons 10 va successivement au gré de son basculement de la position verticale à la position horizontale, prendre appui sur l'élément de soutien 25 ou 26 qui lui correspond, en sorte qu'au final, pratiquement l'intégralité de structure 1 est supportée par ces éléments de soutien 25 et 26.It will be understood that each of the sections 10 will successively, as it tilts from the vertical position to the horizontal position, rest on the support element 25 or 26 which corresponds to it, so that in the end, practically the entire structure 1 is supported by these support elements 25 and 26.

Il est à noter que selon cette variante le guidage des galets 121 du côté interne de la branche 22 n'est plus nécessaire.It should be noted that according to this variant the guiding of the rollers 121 on the internal side of the branch 22 is no longer necessary.

En référence maintenant à la figure 13, on peut voir un autre mode de réalisation 5 du dispositif de fermeture selon l'invention, et qui constitue un mode de réalisation préférentiel.Referring now to the Figure 13 , we can see another embodiment 5 of the closure device according to the invention, and which constitutes a preferred embodiment.

On retrouve sur cette figure 13, le chemin de guidage 20 ramifié en deux branches secondaires 21 et 22, dans lesquels peuvent se déplacer des moyens d'indexage 50, en l'occurrence des galets.We find on this figure 13 , the guide path 20 branched into two secondary branches 21 and 22, in which indexing means 50, in this case rollers, can move.

Les galets 50 sont portés chacun axialement à l'extrémité d'une barre 51, qui forme avec une autre barre 51 qui lui est parallèle, ainsi qu'avec deux entretoises 52, dont une seule est visible, un tronçon.The rollers 50 are each carried axially at the end of a bar 51, which forms with another bar 51 which is parallel to it, as well as with two spacers 52, only one of which is visible, a section.

Ce mode de réalisation 5 comporte une came de distribution 53, disposée entre les deux branches secondaires 21 et 22, de manière coplanaire à ces dernières, et montée librement pivotante sur le dormant 2 selon un axe XX' parallèle aux barres. Cette came 53 présente une forme sensiblement triangulaire, et comprend essentiellement une pointe 54 disposée en partie inférieure, un bord de butée 55 situé en regard de la gorge secondaire 21, et un bord de butée 56 situé en regard de la gorge secondaire 22.This embodiment 5 comprises a distribution cam 53, arranged between the two secondary branches 21 and 22, coplanar with the latter, and mounted freely pivoting on the frame 2 along an axis XX' parallel to the bars. This cam 53 has a substantially triangular shape, and essentially comprises a point 54 disposed in the lower part, a stop edge 55 located opposite the secondary groove 21, and a stop edge 56 located opposite the secondary groove 22.

La came de distribution 53 est dimensionnée en sorte qu'au gré de divers pivotements son bord de butée 55 puisse s'engager dans la gorge secondaire 21 et occuper une partie de l'espace susceptible d'être parcouru par un galet 50, ou que son bord de butée 56 puisse s'engager dans la gorge secondaire 22 et occuper une partie de l'espace susceptible d'être parcouru par un galet 50, ou encore que sa pointe 54 puisse obstruer l'accès à la gorge secondaire 21 à un galet 50.The distribution cam 53 is dimensioned so that, following various pivots, its stop edge 55 can engage in the secondary groove 21 and occupy part of the space capable of being traveled by a roller 50, or that its edge of stop 56 can engage in the secondary groove 22 and occupy part of the space likely to be traversed by a roller 50, or its tip 54 can obstruct access to the secondary groove 21 to a roller 50.

En référence maintenant aux figures 14a, 14b et 14c, on peut voir le fonctionnement du dispositif de fermeture 5.Referring now to figures 14a, 14b and 14c , we can see the operation of the closing device 5.

Lors du déplacement d'un galet 50 dans le chemin de guidage 20 en amont de la zone de ramification, il emprunte la gorge secondaire 22 ou 21 selon la position angulaire de la came de distribution 53.When a roller 50 moves in the guide path 20 upstream of the branching zone, it takes the secondary groove 22 or 21 depending on the angular position of the distribution cam 53.

Sur la figure 14a puis 14b, le galet 50 en approche de la zone de ramification, ne peut que s'engager dans la gorge secondaire 21 du fait de la position de la came 53, laquelle a basculée lorsque le galet 50 précédent, engagé dans la gorge secondaire 22 est venu au contact du bord de butée 56.On the figure 14a Then 14b , the roller 50 approaching the branching zone, can only engage in the secondary groove 21 due to the position of the cam 53, which tilted when the previous roller 50, engaged in the secondary groove 22, came in contact with the stop edge 56.

En poursuivant son déplacement dans la gorge secondaire 21, figure 14c, le galet 50 vient au contact du bord de butée 55 de la came 53, alors que le galet 50 précédent n'est plus au contact du bord de butée 56, en sorte que la came 53 bascule et que la pointe 54 obstrue le passage vers la gorge secondaire 21 et libère l'accès à la gorge secondaire 22 pour le galet 50.By continuing its movement in secondary groove 21, figure 14c , the roller 50 comes into contact with the stop edge 55 of the cam 53, while the previous roller 50 is no longer in contact with the stop edge 56, so that the cam 53 tilts and the point 54 obstructs the passage towards the secondary groove 21 and frees access to the secondary groove 22 for the roller 50.

On notera par ailleurs, qu'en alternance, une entretoise 52 sur deux comporte, du côté de son extrémité dirigée vers la ramification, une extension 57 se projetant au-delà de l'axe du galet 50, tandis que le dormant 2 comporte extérieurement à la branche 21 un élément de soutien 25.It will also be noted that alternately, one out of two spacers 52 comprises, on the side of its end directed towards the branching, an extension 57 projecting beyond the axis of the roller 50, while the frame 2 externally comprises to branch 21 a support element 25.

Ainsi, de manière analogue au mode de réalisation représenté sur la figure 11, lors de la progression du galet 50 dans la gorge secondaire 21, l'extension 57 vient dans un premier temps repousser l'entretoise 52 qui est en position d'attente puis vient prendre appui sur l'élément de soutien 25.Thus, analogously to the embodiment shown on the Figure 11 , during the progression of the roller 50 in the secondary groove 21, the extension 57 initially pushes the spacer 52 which is in the waiting position then comes to bear on the support element 25.

Quel que soit le mode de réalisation considéré, la conception simple du dispositif de fermeture selon l'invention permet une fiabilité d'utilisation que n'atteignent pas les dispositifs existants.Whatever the embodiment considered, the simple design of the closing device according to the invention allows reliability of use which is not achieved by existing devices.

De plus, le dispositif de fermeture selon l'invention, intègre, pour certains modes de réalisation, des moyens d'entraînement peu encombrants et également fiables.In addition, the closing device according to the invention integrates, for certain embodiments, drive means that are space-saving and also reliable.
