Description

TRIBUNE RETRACTABLE RETRACTABLE TRIBUNE
La présente invention est relative à une tribune rétractable comprenant au moins deux gradins étages aptes à occuper une première position pliée où les gradins sont placés les uns au dessus des autres et une seconde position déployée où les gradins sont décalés les uns par rapport aux autres formant une tribune, chaque gradin comportant une rangée de sièges pliables.The present invention relates to a retractable platform comprising at least two step stages capable of occupying a first folded position where the steps are placed one above the other and a second extended position where the steps are offset relative to each other forming a grandstand, each tier having a row of folding seats.
L'organisation d'événements ponctuels de grande ampleur tels que par exemple des manifestations sportives, des salons ou des expositions, nécessite le déploiement rapide de matériel. Le matériel utilisé doit pouvoir être très rapidement mis en place et occuper un espace réduit lorsqu'il n'est pas utilisé pour faciliter son stockage.The organization of large-scale one-off events such as sports events, trade fairs or exhibitions requires the rapid deployment of equipment. The equipment used must be able to be very quickly put in place and occupy a small space when it is not used to facilitate its storage.
L'usage de tribunes rétractables est courant, en particulier dans les stades et les gymnases, car il permet d'augmenter ponctuellement le nombre de places assises.The use of retractable stands is common, especially in stadiums and gymnasiums, because it allows to increase the number of seats.
Les tribunes actuelles sont certes rétractables mais elles sont équipées de sièges dont les dossiers doivent être dépliés manuellement avant toute utilisation après déploiement de la tribune. Il existe des tribunes avec des sièges qui se déplient automatiquement après l'ouverture de la tribune mais ces dispositifs nécessitent l'utilisation d'actionneurs dont le coût est élevé.The current stands are retractable but they are equipped with seats whose records must be unfolded manually before use after deployment of the stand. There are stands with seats that unfold automatically after opening the stand but these devices require the use of actuators whose cost is high.
Le déploiement manuel demande un temps considérable et est une opération extrêmement pénalisante.Manual deployment takes a considerable amount of time and is extremely penalizing.
L'invention a pour but, surtout de proposer une tribune dont les sièges deviennent automatiquement utilisables après déploiement de la tribune, sans que l'intervention d'un dispositif externe ne soit nécessaire pour déplier chaque dossier tout en limitant le recours à un opérateur.The invention aims, especially to provide a platform whose seats become automatically usable after deployment of the platform, without the intervention of an external device is necessary to unfold each file while limiting the use of an operator.
Selon l'invention, une barrière rétractable du genre en question est caractérisée en ce qu'elle comporte un moyen de déploiement apte à provoquer le dépliement d'au moins un siège en réaction au passage de la tribune en position déployée.According to the invention, a retractable barrier of the type in question is characterized in that it comprises a deployment means capable of causing the unfolding of at least one seat in response to the passage of the platform in the deployed position.
Avantageusement, le moyen de déploiement est activé par le mouvement relatif d'au moins un premier gradin par rapport à au moins un second gradin. Le siège peut être équipé d'un dossier rabattable.Advantageously, the deployment means is activated by the relative movement of at least a first step relative to at least a second step. The seat can be equipped with a folding backrest.
Avantageusement, au moins un gradin comporte un moyen de traction permettant de provoquer le déploiement d'une première rangée de sièges lorsque la tribune passe en position déployée. Le moyen de traction peut comporter une tige coulissante par rapport au gradin comportant un premier élément formant crochet, apte à s'accrocher au gradin immédiatement inférieur, et un second élément apte à coopérer avec un siège pour permettre le déploiement dudit siège. Le second élément peut comporter un doigt coopérant avec un orifice prévu sur un levier solidaire du dossier.Advantageously, at least one step comprises a traction means for causing the deployment of a first row of seats when the grandstand goes into the deployed position. The pulling means may comprise a sliding rod relative to the step comprising a first hook member, adapted to engage the immediately lower step, and a second member adapted to cooperate with a seat to allow the deployment of said seat. The second element may comprise a finger cooperating with an orifice provided on a lever secured to the file.
De manière avantageuse, au moins un gradin comporte un moyen de poussée permettant le repliement d'une seconde rangée de sièges lorsque la tribune passe en position pliée. La première rangée peut être distincte de la seconde rangée de sièges. Le moyen de poussée peut alors être constitué par le gradin immédiatement supérieur.Advantageously, at least one step comprises a thrust means for folding a second row of seats when the grandstand goes into the folded position. The first row may be distinct from the second row of seats. The thrust means can then be constituted by the next higher step.
La première rangée peut également être identique à la seconde rangée de sièges. Dans ce cas le moyen de poussée peut comprendre un crochet apte à s'accrocher au gradin immédiatement inférieur.The first row can also be identical to the second row of seats. In this case the thrust means may comprise a hook adapted to hook to the next lower step.
Les sièges à déplier peuvent être sélectionnés avant l'ouverture de la tribune.Unfolding seats can be selected before opening the grandstand.
Les sièges plies peuvent être dépliés manuellement par un opérateur lorsque la tribune est déployée. D'autres caractéristiques et avantages de l'invention apparaîtront dans la description qui suit d'un mode de réalisation préféré avec référence aux dessins annexés mais qui n'a aucun caractère limitatif. Sur ces dessins :The folded seats can be unfolded manually by an operator when the grandstand is deployed. Other features and advantages of the invention will appear in the following description of a preferred embodiment with reference to the accompanying drawings but which has no limiting character. On these drawings:

Dans toute la description qui suit d'un mode de réalisation d'une tribune rétractable selon l'invention, les termes relatifs tels que « supérieur », « inférieur », « avant », « arrière », « horizontal » et « vertical » sont à interpréter lorsque la tribune rétractable selon l'invention est installée en situation de fonctionnement. On considère que la direction longitudinale est la direction suivant laquelle sont alignés les sièges sur un même gradin. Les gradins sont mobiles les uns par rapport aux autres suivant une direction transversale.Throughout the following description of an embodiment of a retractable platform according to the invention, the relative terms such as "upper", "lower", "front", "rear", "horizontal" and "vertical" are to be interpreted when the retractable platform according to the invention is installed in situation Operating. It is considered that the longitudinal direction is the direction in which the seats are aligned on the same step. The steps are movable relative to each other in a transverse direction.
On peut voir sur Fig. 1 , Fig. 2 et Fig. 3 une tribune T selon l'invention. La tribune T comporte trois gradins A, B et C disposés les uns au dessus des autres de manière à occuper un espace réduit (Fig. 1 ). Les gradins A, B et C comportent des dispositifs de roulement non-représentés permettant au gradin B d'être déplacé suivant une direction transversale par rapport au gradin A et au gradin C d'être déplacé suivant une direction transversale par rapport au gradin B. Des supports additionnels, non représentés, sont également mis en place et permettent un appui des gradins A, B et C sur le sol.We can see on Fig. 1, Fig. 2 and FIG. 3 a tribune T according to the invention. The grandstand T has three steps A, B and C arranged one above the other so as to occupy a small space (Fig. 1). Steps A, B and C have unrepresented rolling devices allowing step B to be moved in a direction transverse to step A and step C to be moved in a direction transverse to step B. Additional supports, not shown, are also put in place and allow support of the terraces A, B and C on the ground.
Chaque gradin A, B, C comporte une rangée de sièges 1 équipés de dossiers rabattables 2 articulés par rapport à l'assise des sièges 1. Les dossiers 2 sont rabattus lorsque la tribune T est rétractée ou pliée (Fig. 1 ). Les dossiers 2 sont partiellement déployés Fig. 2 lorsque la tribune est partiellement dépliée. Enfin les dossiers 2 sont totalement déployés Fig. 3 lorsque la tribune T est totalement déployée.Each step A, B, C comprises a row of seats 1 equipped with foldable backs 2 articulated with respect to the seat of the seats 1. The backrests 2 are folded down when the stand T is retracted or folded (Fig. 1). Folders 2 are partially deployed Fig. 2 when the stand is partially unfolded. Finally the folders 2 are fully deployed Fig. 3 when the T stand is fully deployed.
Le mécanisme utilisé pour le déploiement des dossiers 2 est plus particulièrement illustré Fig. 4 à Fig. 8. On note 1 a les sièges du gradin A, 1 b ceux du gradin B et 1 c ceux du gradin C. On procède de la même façon pour les dossiers 2 et les autres éléments décrits. Les sièges 1 a et les dossiers 2a ne sont pas visibles sur les figures.The mechanism used for the deployment of the files 2 is more particularly illustrated. 4 to FIG. 8. The seats in step A, 1 b in step B and 1 c in step C are marked 1a. The same procedure is used for folders 2 and the other elements described. The seats 1a and 2a folders are not visible in the figures.
Chaque dossier 2 est solidaire d'un levier 3. Le levier 3 comporte une première extrémité sensiblement rectangulaire solidaire du dossier 2 et une seconde extrémité libre comportant un évidement oblong 4. Entre la première extrémité et la seconde extrémité du levier 3, un orifice 5 est prévu permettant une articulation avec l'assise du siège 1.Each backrest 2 is integral with a lever 3. The lever 3 comprises a first substantially rectangular end secured to the backrest 2 and a second free end having an oblong recess 4. Between the first end and the second end of the lever 3, an orifice 5 is provided allowing articulation with the seat of the seat 1.
Les sièges 1 sont solidaires d'un plancher 6 de chaque gradin A, B, C. La seconde extrémité du levier 3 et l'évidement oblong 4 sont recourbés suivant un quart de cercle. De cette façon, lorsque le dossier 2 est totalement rabattu, l'extrémité libre du levier 3 et l'extrémité distale de l'évidement oblong 4 se situent sous le niveau du plancher 6 du gradin A, B, C.The seats 1 are integral with a floor 6 of each step A, B, C. The second end of the lever 3 and the oblong recess 4 are curved along a quarter circle. In this way, when the back 2 is completely folded down, the free end of the lever 3 and the distal end of the oblong recess 4 are below the level of the floor 6 of the step A, B, C.
En variante, illustrée Fig. 7 et 8, la seconde extrémité du levier 3 est droite. Sur Fig. 7 et Fig. 8 une seule rangée de sièges est représentée et les indices des éléments ne sont pas mentionnés. Par exemple la tige notée 7 surIn a variant, illustrated in FIG. 7 and 8, the second end of the lever 3 is straight. In Fig. 7 and FIG. 8 only one row of seats is represented and the indices of the elements are not mentioned. For example the rod noted 7 on
Fig. 7 et Fig. 8 correspond aux tiges 7a, 7b et 7c de Fig. 1 à Fig. 6. On procède de la même façon pour les autres éléments décritsFig. 7 and FIG. 8 corresponds to the rods 7a, 7b and 7c of FIG. 1 to Fig. 6. The same procedure is followed for the other elements described
Une tige 7 est montée de manière coulissante sous le plancher 6, guidée par des manchons 8. La tige 7 est montée suivant une direction transversale, parallèlement à la direction suivant laquelle peuvent se déplacer les gradins A, B, C.A rod 7 is slidably mounted under the floor 6, guided by sleeves 8. The rod 7 is mounted in a transverse direction, parallel to the direction in which can move the steps A, B, C.
La tige 7 est solidaire d'un crochet 9 s'étendant perpendiculairement vers le bas par rapport à la tige 7. La tige 7 est également solidaire d'un doigt 10 s'étendant perpendiculairement à la tige 7 et sensiblement parallèlement au plancher 6 de manière à pénétrer dans l'évidement oblong 4.The rod 7 is integral with a hook 9 extending perpendicularly downwardly relative to the rod 7. The rod 7 is also integral with a finger 10 extending perpendicularly to the rod 7 and substantially parallel to the floor 6 of way to penetrate the oblong recess 4.
L'extrémité du gradin A, B, C opposée au siège 1 comporte une butée 1 1 s'étendant verticalement vers le haut au dessus de l'extrémité inférieure du crochet 9. En fonctionnement, lorsque la tribune T est repliée (Fig. 1 et Fig. 4) et que des opérateurs la déplient, les butées 1 1 de chaque gradin A, B, C entraînent les crochets 9 correspondants des tiges 7 coulissant par rapport au gradin immédiatement supérieur. Par exemple, les butées 1 1 a entraînent les crochets 9b et les butées 1 1 b entraînent les crochets 9c. De cette façon les tiges 7 sont entraînées en translation et entraînent les doigts 10 (Fig. 2 et Fig. 5). Les doigts 10 coopèrent avec les évidements oblongs 4 et provoquent le déploiement des dossiers 2 par l'intermédiaire des leviers 3 (Fig. 3 et Fig. 6).The end of the step A, B, C opposite the seat 1 comprises a stop 1 1 extending vertically upwards above the lower end of the hook 9. In operation, when the platform T is folded (Fig. 1 and Fig. 4) and that operators unfold it, the stops 1 1 of each step A, B, C cause the corresponding hooks 9 of the rods 7 sliding relative to the next higher step. For example, the stops 1 1 a drive the hooks 9b and abutments 11b result in the hooks 9c. In this way the rods 7 are driven in translation and drive the fingers 10 (Fig 2 and Fig 5). The fingers 10 cooperate with the oblong recesses 4 and cause the deployment of the backs 2 by means of the levers 3 (Fig 3 and Fig 6).
Lorsque la tribune est repliée, les gradins A, B, C repoussent les dossiers 2 qui entraînent les tiges 7 par l'intermédiaire des leviers 3. En effet lorsque les gradins sont repliés, les butées 11 n'exercent plus d'action sur les crochets 9 et permettent donc le coulissement des tiges 7.When the grandstand is folded, the stands A, B, C push the backs 2 which drive the rods 7 by means of the levers 3. Indeed when the stands are folded, the abutments 11 no longer exert action on them. hooks 9 and thus allow the sliding of the rods 7.
En variante, la tige 7 comporte un second crochet 12 fixé à l'opposé du crochet 9. Lorsque le gradin immédiatement inférieur est replié, la butée 1 1 entraine la tige 7 par l'intermédiaire du crochet 12, provoquant le repliement du dossier 2. Alternatively, the rod 7 comprises a second hook 12 fixed opposite the hook 9. When the next lower step is folded, the stop 1 1 drives the rod 7 through the hook 12, causing the folding of the backrest 2 .
