Description

L'invention concerne une barrière extensible sur roulettes réalisée par assemblage d'éléments modulaires pivotants déployable et repliable manuellement.The invention relates to an expandable barrier on wheels made by assembling pivotable modular elements deployable and foldable manually.

On connaît déjà une barrière en losanges étirables sur câble guide pour voies routières, urbaines ou piétonnières décrite dans le document FR 2 688 244 . Cette barrière présente les inconvénients suivants: elle est réalisée en acier traité anti-corrosion, de ce fait elle est très lourde à manipuler. Elle est manoeuvrée sur un câble de guidage tendu entre deux points fixes, par au moins un câble sur laquelle elle est immobilisée; ce câble est tracté par un système mécanique à treuil manuel, semi-automatique ou automatique. Il n'est pas détaillé de mécanisme pour la déployer, mais seulement pour la replier sauf sur la figure 5 présentant un système à câble non décrit, avec une boucle de retour dans un rail de guidage pour des installations fixes. Pour ouvrir le passage, il faut tirer avec un tire-câble. Il n'est pas mentionné qu'il faut retirer le ou les câbles qui empêchent l'accès quant la barrière est repliée et gênent le passage des piétons ou des véhicules et comment on les enlève pour libérer très rapidement l'accès. De même pour fermer l'accès il est mentionné un tire-câble non représenté. Il faut remettre manuellement les câbles en place, les tendre avant de déployer la barrière. La barrière est immobilisée non entre les points fixes, mais sur le câble à chaque extrémité par des serre-câble. Il faut desserrer les serre-câble du côté du treuil pour pouvoir replier la barrière. Ces divers moyens sont compliqués, très onéreux et très lents à manoeuvrer. Etant donné ses utilisations à l'extérieur, soumise aux intempéries, elle est appelée à subir des chocs qui représenteront chacun un point de rouille. Elle comporte des angles saillants dangereux pour les piétons qu'elle est chargée de canaliser. Elle ne comporte pas de moyens d'adaptation tenant compte des passages de trottoir ou d'irrégularités du sol des sites sur lesquels elle doit être déployée, elle reste suspendue sur son câble. Elle ne comporte pas de sécurité de limite de déploiement qui est laissé à l'initiative de celui qui la met en place avec les serre-câbles.We already know a barrier rhombus barrier on guide wire for roads, urban or pedestrian described in the document FR 2,688,244 . This barrier has the following disadvantages: it is made of anti-corrosion treated steel, so it is very heavy to handle. It is maneuvered on a guide wire stretched between two fixed points, by at least one cable on which it is immobilized; this cable is towed by a mechanical system with manual winch, semi-automatic or automatic. It is not detailed mechanism to deploy it, but only to fold it except in Figure 5 having a cable system not described, with a return loop in a guide rail for fixed installations. To open the passage, pull with a cable puller. It is not mentioned that it is necessary to remove the cable or cables that prevent access when the barrier is folded and obstruct the passage of pedestrians or vehicles and how to remove them to release access very quickly. Similarly to close the access is mentioned a not shown cable puller. The cables must be manually re-attached, tensioned before deploying the barrier. The barrier is immobilized not between the fixed points, but on the cable at each end by cable clamps. Loosen the cable clamps on the side of the winch to be able to fold the barrier. These various means are complicated, very expensive and very slow to maneuver. Given its outdoor uses, subjected to bad weather, it is expected to suffer shocks that will each represent a rust. It has dangerous angles for the pedestrians it is responsible for channeling. It does not include means of adaptation taking into account the sidewalks or irregularities of the ground of the sites on which it must be deployed, it remains suspended on its cable. It does not have deployment limit security that is left to the initiative of the one who puts it in place with the cable ties.

Cette barrière est lourde, compliquée, et nécessite des moyens très onéreux pour sa mise en place son déploiement et pour la replier et la transporter dans le cas d'installations provisoires.This barrier is cumbersome, complicated, and requires very expensive means for setting up its deployment and for folding and transporting it in the case of temporary installations.

Les problèmes à résoudre pour réaliser une barrière légère déployable et repliable rapidement manuellement et facile à transporter et mettre en oeuvre sur les sites d'utilisation sont les suivants:

  • pouvoir réaliser une barrière légère mais robuste, déployable et repliable manuellement rapidement, préférablement par une seule personne;
  • pouvoir limiter positivement son déploiement pour empêcher son allongement au-delà de sa limite de bonne stabilité latérale;
  • pouvoir accroître sa stabilité latérale et surtout sa résistance au renversement, particulièrement pour les grandes longueurs;
  • pouvoir conserver un bon appui au sol sur toute sa longueur même sur sol inégal (passage de trottoirs) pour conserver sa stabilité latérale sans la faire travailler à la torsion;
  • pouvoir la verrouiller sur ses points fixes à ses deux extrémités pour éviter que quiconque puisse l'ouvrir sans autorisation;
  • pouvoir résister à la corrosion même en cas de chocs en cours de manipulations;
  • éviter les angles saillants dangereux pour les personnes circulant à proximité;
  • pouvoir rendre la barrière visible la nuit, même en cas de panne de courant électrique.
The problems to be solved to realize a light barrier deployable and foldable quickly manually and easy to transport and implement on the sites of use are the following:
  • be able to achieve a light but robust barrier, deployable and foldable manually quickly, preferably by one person;
  • be able to positively limit its deployment to prevent its elongation beyond its limit of good lateral stability;
  • be able to increase its lateral stability and especially its resistance to overturning, especially for long lengths;
  • ability to maintain good ground support throughout its length even on uneven ground (sidewalks) to maintain its lateral stability without making it work with torsion;
  • be able to lock it on its fixed points at both ends to prevent anyone from opening it without authorization;
  • ability to resist corrosion even in the event of shocks during handling;
  • avoid sharp angles that are dangerous for people traveling nearby;
  • be able to make the barrier visible at night, even in the event of a power failure.

Tous ces problèmes sont résolus avec la barrière extensible sur roulettes selon la revendication 1, la barrière extensible renforcée latéralement selon la revendication 7 et la barrière sur patins selon la revendication 19, la dite barrière étant constituée d'éléments modulaires pivotants entre eux en alliage léger traité anti-corrosion tous identiques, chacun comportant deux branches verticales en forme de X pivotant sur une tige en leur centre et à leurs extrémités sur l'élément suivant, la rendant déployable et repliable manuellement; les éléments d'extrémités de la barrière sont munis chacun de moyens de fixation, préférablement verrouillables, chacun sur un point fixe correspondant pour son immobilisation en position déployée entre lesdits points fixes solidaires du site ou rapportés sous forme d'un poteau métallique ancrés provisoirement ou définitivement sur celui-ciAll these problems are solved with the expandable barrier on wheels according to claim 1, the laterally reinforced expandable barrier according to claim 7 and the skid barrier according to claim 19, said barrier consisting of modular elements pivoting among themselves of light alloy. anti-corrosion treated all identical, each having two vertical branches X-shaped pivoting on a rod in their center and at their ends on the next element, making it deployable and foldable manually; the end elements of the barrier are each provided with fastening means, preferably lockable, each on a corresponding fixed point for its immobilization in the deployed position between said fixed points integral with the site or reported in the form of a metal pole provisionally anchored or definitely on this one

Les deux extrémités de ladite barrière peuvent être terminées chacune par un élément modulaire complet en X, ces extrémités comportant chacune soit deux ou quatre moyens de fixation en position déployée sur un point fixe correspondant du site, lesdites fixations agissant ensemble en limiteur de déploiement de la barrière et en stabilisateurs latérauxThe two ends of said barrier may each be terminated by a complete modular X element, said ends each having either two or four fastening means in deployed position on a corresponding fixed point of the site, said fasteners acting together as a deployment limiter of the barrier and in lateral stabilizers

Ses deux extrémités en variante se terminent chacune par un élément modulaire spécial formé d'un demi élément normal en Vé pivotant en triangle muni, à son extrémité pivotante, d'au moins un moyen de fixation sur le point fixe correspondant du site.Its two ends alternatively each end with a special modular element formed of a normal half Vee pivoting triangle element provided at its pivoting end, at least one fastening means on the corresponding fixed point of the site.

Son moyen de limitation de déploiement entre deux points de fixation du site est constitué par au moins une chaînette tendue entre deux éléments modulaires successifs ou encore par deux biellettes identiques articulées entre elle et entre deux pivots centraux de deux éléments modulaires en X successifs. Chacune de ses roulettes est fixée sur l'extrémité d'une tige coulissant dans un tube solidaire de l'élément modulaire correspondant, comportant une butée haute définissant la position normale rentrée de chacune des roulettes, la position basse, variable en fonction de la dénivellation du site, étant maintenue par un moyen auto-bloquant sur la tige porte-roulette tant en position basse qu'en position haute, ce qui permet de l'appuyer sur un sol inégal sur toute sa longueur.Its deployment limiting means between two points of attachment of the site is constituted by at least one chain tensioned between two successive modular elements or by two identical links articulated between it and between two central pivots of two modular elements X successive. Each of its wheels is fixed on the end of a sliding rod in a tube integral with the corresponding modular element, having a high stop defining the normal retracted position of each of the wheels, the low position, variable depending on the level of the site, being maintained by a self-locking means on the rod holder wheel in both the low position and high position, which allows to press on uneven ground on any its length.

Pour les barrières de grande longueur nécessitant une plus grande stabilité latérale, le renforcement de cette stabilité est obtenu au moyen de l'assemblage d'éléments modulaires comportant deux branches verticales en forme de X pivotant en leur centre, dont les deux branches d'un même côté sont prolongées d'un pas au-delà de l'extrémité des branches du module normal, lesdites branches prolongées comportant un 4ème pivot à leur extrémité prolongée pour leur fixation sur le module identique suivant ou sur un module spécial d'extrémité. Lorsqu'elle est constituée par l'assemblage d'éléments modulaires à stabilité latérale renforcée, ses modules spéciaux d'extrémité comportent une branche de l'élément modulaire normal coopérant avec une branche de l'élément modulaire spécial de façon à ce que lesdites branches de cet élément modulaire spécial se terminent sur un même plan vertical perpendiculaire à l'axe longitudinal de ladite barrière, l'extrémité libre de la branche du module normal pivotant sur une branche courte pivotant également à l'extrémité de la branche prolongée de l'élément modulaire précédent, lesdites extrémités étant munies chacune de moyens de fixation avec ou sans verrouillage sur la partie fixe du site pour l'immobilisation de ladite barrière.For long barriers requiring greater lateral stability, the reinforcement of this stability is obtained by means of the assembly of modular elements comprising two vertical branches in the form of X pivoting in their center, whose two branches of a same side are extended one step beyond the end of the branches of the normal module, said extended legs having a fourth pivot at their extended end for attachment to the next identical module or a special end module. When constituted by the assembly of modular elements with reinforced lateral stability, its special end modules comprise a branch of the normal modular element cooperating with a branch of the special modular element so that said branches of this special modular element end on the same vertical plane perpendicular to the longitudinal axis of said barrier, the free end of the branch of the normal module pivoting on a short branch also pivoting at the end of the extended branch of the preceding modular element, said ends being each provided with fastening means with or without locking on the fixed part of the site for the immobilization of said barrier.

En variante, ses deux modules spéciaux d'extrémité comportent deux branches de l'élément modulaire normal coopérant avec une branche du module spécial et une branche courte de la longueur d'un pas de façon à former un triangle d'extrémité muni d'un moyen de fixation sur un point fixe du site, l'autre extrémité de ladite barrière renforcée pouvant être symétrique ou identique à l'autre.As a variant, its two special end modules comprise two branches of the normal modular element cooperating with a branch of the special module and a short branch of the length of a pitch so as to form an end triangle provided with a fixing means on a fixed point of the site, the other end of said reinforced barrier being symmetrical or identical to the other.

La branche principale des éléments modulaires comporte un profilé en forme de U muni de moyens de clipage d'un profilé de main courante. Des barreaux sont fixés entre deux portions de ce profilé qui comporte des trous de passage des tiges pivot fixées sur celles-ciThe main branch of the modular elements comprises a U-shaped profile provided with means for clipping a profile of handrail. Bars are fixed between two portions of this profile which has holes for passing the pivot rods fixed thereto.

Les branches secondaires des éléments modulaires sont constituées avec deux portions d'un profilé en U comportant des moyens de clipage d'un capot. Ce profilé est percée de trous de fixation des barreaux et, au droit des articulations, comporte un trou poinçonné pour le passage d'un barreau dans lequel passe la tige pivot.The secondary branches of the modular elements are constituted by two portions of a U-shaped section comprising means for clipping a cover. This section is pierced with fixing holes of the bars and, in line with the joints, comprises a punched hole for the passage of a bar in which the pivot rod passes.

Les barreaux sont de section rectangulaire à angles arrondis, le milieu de la face intérieure de ses deux petits côtés comporte une alvéovis de fixation au moyen de quatre vis entre les profilés.The bars are of rectangular section with rounded corners, the middle of the inner face of its two short sides has a fixing alveovis by means of four screws between the profiles.

Le pivotement des branches secondaires des éléments modulaires entre les profilés des branches principales munies de leurs barreaux, s'effectue au moyen d'une tige engagée dans les trous correspondants desdits profilés, des écrous la bloque sur les deux profilés de la branche principale en laissant subsister un léger jeu pour permettre à la branche secondaire de pivoter aisément.Pivoting of the secondary branches of the modular elements between the profiles of the main branches provided with their bars, is effected by means of a rod engaged in the corresponding holes of said profiles, nuts locks on the two profiles of the main branch leaving stay a slight game to allow the secondary branch to rotate easily.

Les extrémités des branches secondaires comportent un système de patin escamotable d'appui au sol muni d'un moyen d'immobilisation rapide en position repos ou d'appui au soLThe ends of the secondary branches comprise a retractable foot support system provided with a means of rapid immobilization in the rest position or of support to the soil.

Les barrières sont réalisées par assemblage d'autant d'éléments modulaires normaux ou spéciaux en X, que nécessaire avec leurs éléments d'extrémité comportant leurs moyens de fixation pouvant être verrouillables par cadenas ou serrure.The barriers are made by assembling as many normal or special modular elements X, as necessary with their end members having their fastening means that can be lockable by padlock or lock.

Leur transport et leur mise en place provisoire sur un site, lorsqu'elle doivent être de grande longueur, est effectué en plusieurs tronçons repliés, facilement chargeables sur un camion avec un chariot élévateur. Les tronçons sont assemblés entre eux par des plaque de liaison rendues solidaires de pièces de fermeture des profilés des branches principales, prolongées à l'extérieur par une plaque percée d'un gros trou dans lequel est engagée une tige épaulée verrouillée par la boucle d'un cadenas.Their transport and their provisional placement on a site, when it must be of great length, is carried out in several folded sections, easily loadable on a truck with a forklift. The sections are assembled together by connecting plates made integral with closure parts of the profiles of the main branches, extended to the outside by a plate pierced with a large hole in which is engaged a shoulder pin locked by the buckle. a padlock.

Le verrouillage de ses pièces de fermeture d'extrémité sur les points fixes correspondants du site est constitué par une chape dans laquelle une tige épaulée est engagée et verrouillée par un cadenas. La chape est prolongée par une tige filetée engagée dans un trou d'une plaque métallique et bloquée au moyen quatre écrous après interposition de chaque côté de la plaque de rondelles coniques d'amortissement des efforts exercés sur la barrière.

Les figures 1 et 2 montrent, vu en perspective et vu de dessus, l'exemple d'éléments modulaires 1 articulés en 2 en forme de X pour constituer, lorsqu'ils sont assemblés, une barrière extensible selon l'invention de longueur quelconque, à la demande des utilisateurs. Le détail de son mode de construction est présenté sur les fig. 16 à 22. Elle comporte d'un côté, sur le module 1A, deux moyens 3, 4 identiques, de fixation sur le site équipé de moyens complémentaires verrouillables. Son module spécial d'extrémité 5, en forme de triangle dit en Vé pivotant en 6, comporte un seul moyen 7 de fixation sur le site, identique aux moyens 3,4. Dans le cas ou l'on désirerait une stabilité accrue de la barrière en lui conférant une importante résistance anti-renversement, on peut ajouter un moyen inférieur 8 identique aux autres 3, 4, 7. On montrera fig. 27 un mode préférentiel de fixation des modules d'extrémité sur le site. Chaque élément modulaire possède deux roulettes pivotantes 10, 11, disposées en opposition en partie basse permettant de déployer et de replier facilement la barrière. Chaque élément modulaire comporte en partie supérieure, une main courante 12. Chaque élément modulaire simple ou renforcé ainsi que les éléments modulaires spéciaux d'extrémité sont constitués en deux branches 14,15 de hauteur différente, la branche secondaire 15 pivotant à l'intérieur de la branche principale 14. La branche 14 comporte deux profilés 16 entre lesquels sont fixés des profilés 17 dénommés les barreaux. Le profilé 12 de main courante est clipé sur le profilé 16. Les barreaux 18 de la branche 15 sont plus courts que ceux 17 de la branche 14. La branche 15 est constituée par deux profilés identiques 20 entre lesquels sont fixés par sertissage les barreaux 18. Le détail des extrémités pivotantes 6 sera vu fig. 22 et 28. FIGS. 1 and 2 show, seen in perspective and seen from above, the example of modular elements 1 hinged at 2 in the form of X to form, when assembled, an extensible barrier according to the invention of any length, at the request of users. The details of its method of construction are presented in figs. 16 to 22. It comprises on one side, on the module 1A, two identical means 3, 4 for fixing on the site equipped with lockable complementary means. Its special end module 5, in the form of a triangle said V-swiveling at 6, has a single means 7 for fixing on the site, identical to the means 3,4. In the case where one would desire increased stability of the barrier by giving it a high anti-rollover resistance, one can add a lower means 8 identical to the others 3, 4, 7. It will be shown FIG. 27 a preferential mode of fixing the end modules on the site. Each modular element has two swivel castors 10, 11, arranged in opposition at the bottom to easily deploy and fold the barrier. Each modular element comprises in the upper part, a handrail 12. Each simple or reinforced modular element as well as the special end modular elements are constituted by two branches 14,15 of different height, the secondary branch 15 pivoting inside of the main branch 14. The branch 14 comprises two profiles 16 between which are fixed profiles 17 called bars. The profile 12 of handrail is clipped onto the profile 16. The bars 18 of the branch 15 are shorter than those 17 of the branch 14. The branch 15 is constituted by two identical sections 20 between which are fixed by crimping the bars 18 The details of the pivoting ends 6 will be seen fig. 22 and 28.

Les figures 3 et 4 montrent schématiquement en vue de dessus une variante de barrière constituée d'éléments modulaires 1 pivotant en X et d'éléments modulaires spéciaux 5 d'extrémité à pivot en Vé à une seule fixation 4, 7, coopérant avec les moyens complémentaires du site. La figure 3 montre les éléments modulaires 1 séparés avant assemblage, terminés par deux éléments 5 en Vé et assemblés comme sur la figure 4. La chaînette 22 de la figure 5 a pour fonction de limiter le déploiement des barrières terminées par deux éléments modulaires spéciaux en Vé. Figures 3 and 4 schematically show a top view of a barrier variant consisting of modular elements 1 pivoting X and special modular elements 5 V end pivot to a single attachment 4, 7 cooperating with the means complementary of the site. FIG. 3 shows the modular elements 1 separated before assembly, terminated by two V elements 5 and assembled as in FIG. 4. The function of the chain 22 of FIG. 5 is to limit the deployment of the barriers terminated by two special modular elements in FIG. vee.

Les figures 6 et 7 montrent schématiquement en vue de dessus une variante de barrière constituée d'éléments modulaires 1 à deux fixations 3, 4 d'un côté sur l'élément 1A et à une seule fixation 7 sur l'élément 5 en Vé à l'autre extrémité. Les fixation 3,4 de l'élément 1A assurent l'auto-limitation du déploiement de la barrière, même si, à l'autre extrémité elle est terminée par un élément modulaire 5 en Vé. Figures 6 and 7 schematically show a top view of a barrier variant consisting of modular elements 1 with two fasteners 3, 4 on one side on the element 1A and a single attachment 7 on the element 5 Vee the other extremity. The attachment 3,4 of the element 1A ensure the self-limitation of the deployment of the barrier, even if at the other end it is terminated by a modular element 5 Vee.

Les figures 8 et 9 montrent schématiquement en vue de dessus une variante de barrière constituée d'éléments modulaires 1 pivotants en X, non assemblés, dont les éléments d'extrémité 1A comportent au moins deux fixations 3, 4 à chaque extrémité sur des points fixes du site. La fig. 9 montrent les éléments modulaires assemblés tendus entre les points fixes du site S1, S2. FIGS. 8 and 9 schematically show a top view of a barrier variant consisting of unassembled X-shaped modular elements 1, whose end elements 1A comprise at least two fasteners 3, 4 at each end on fixed points. of the site. Fig. 9 show assembled modular elements stretched between the fixed points of the site S1, S2.

Les figure 10 et 11 montrent vu en perspective et vu de dessus, montrent un exemple d'éléments modulaires identiques séparés 25 de constitution d'une barrière extensible renforcée latéralement selon l'invention comportant de chaque côté un élément modulaire spécial en Vé 26 à gauche et 27 à droite munis chacun, à leur articulation, d'un moyen de fixation 4, 7 entre deux points fixes du site S1 et S2. Ces éléments modulaires renforcés comportent chacun une partie ou branche prolongée d'un pas 29 du même côté et terminée par un 4éme pivot. L'élément modulaire 26 d'extrémité gauche en Vé comporte une branche 30 à deux pas (le pas étant la distance entre deux pivots d'une même branche, tous les pas étant identiques pour une même barrière) et une branche 31 d'un seul pas pivotant entre elles, la branche 31 comportant un moyen de fixation 4 sur le site S1. L'élément modulaire suivant 28 est spécial car il comporte une branche normale 33 à trois pas et sa seconde branche 34 à deux pas, le pivot 35 en X étant située sur le premier pas. Ces éléments modulaires renforcés sont constitués, au pas supplémentaire près, de la même façon que les éléments modulaires des barrières non renforcées. L'élément modulaire 27 de la seconde extrémité est différent de son opposé 26 en ce qu'il comporte une branche supplémentaire à deux pas et trois pivots s'assemblant avec l'élément normal suivant 25. Figures 10 and 11 show seen in perspective and seen from above, show an example of identical identical modular elements 25 of a constitution of a laterally reinforced extensible barrier according to the invention having on each side a special modular element Vé 26 left and 27 on the right each provided, at their articulation, a fixing means 4, 7 between two fixed points of the site S1 and S2. These reinforced modular elements each comprise a portion or branch extended a step 29 on the same side and finished by a 4-th pivot. The modular element 26 of left end Vee comprises a branch 30 with two steps (the step being the distance between two pivots of the same branch, all the steps being identical for the same barrier) and a branch 31 of a not only pivoting between them, the branch 31 having a fixing means 4 on the site S1. The following modular element 28 is special because it comprises a normal branch 33 with three steps and its second branch 34 with two steps, the pivot 35 X being located on the first step. These reinforced modular elements are constituted, at the extra step, in the same way as the modular elements of unreinforced barriers. The modular element 27 of the second end is different from its opposite 26 in that it comprises an additional branch with two steps and three pivots assembling with the next normal element 25.

Les figures 12 et 13 montrent vu de dessus, un autre exemple d'éléments modulaires de constitution d'une barrière extensible renforcée latéralement selon l'invention comportant de chaque côté une double fixation 3, 4 entre deux points fixes du site S1 et S2 accroissant sa résistance au renversement. Elle est constituée par l'assemblage du nombre d'éléments modulaires normaux 25 nécessaires pour obtenir la longueur définie de la barrière et terminée à ses deux extrémités par deux éléments modulaires symétriques 40 et 41 constitués chacun d'une branche normale à trois pas 33, d'une branche 30 à deux pas et d'une branche 31 à un pas articulée sur la branche 30. La figure 13 montre les différents éléments modulaires assemblés entre eux pour constituer la barrière. On voit d'après cette figure, que lorsque les extrémités 40, 41 de cette barrière renforcée sont fixées en deux ou quatre points de chaque côté sur des parties fixes du site, que cette barrière, même très longue, n'est pas renversable. Figures 12 and 13 show seen from above, another example of modular elements of constitution of a laterally reinforced extensible barrier according to the invention having on each side a double attachment 3, 4 between two fixed points of the site S1 and S2 increasing its resistance to reversal. It consists of assembling the number of normal modular elements necessary to obtain the defined length of the barrier and terminated at its two ends by two symmetrical modular elements 40 and 41 each consisting of a normal three-step branch 33, a branch 30 with two steps and a branch 31 at a not articulated on the branch 30. Figure 13 shows the different modular elements assembled together to form the barrier. It can be seen from this figure that when the ends 40, 41 of this reinforced barrier are fixed in two or four points on each side on fixed parts of the site, this barrier, even very long, is not reversible.

Les figures 14 et 15 montrent vu de dessus, un exemple de variante d'éléments modulaires normaux 25 de constitution d'une barrière extensible renforcée latéralement selon l'invention comportant de chaque côté des éléments d'extrémité en Vé 26 et 27 fixés entre deux points fixes S1, S2 du site et la barrière ainsi assemblée fig. 15. Pour des barrières de ce type, il est préférable d'avoir au moins un module 40 ou 41 à l'une de ses extrémité pour bénéficier de sa capacité anti-renversement et mieux encore, d'avoir des éléments modulaires d'extrémité à quatre points de fixation de chaque côté sur un mur ou des poteaux ancrés sur le site. FIGS. 14 and 15 show, seen from above, an exemplary variant of normal modular elements 25 constituting a laterally reinforced extensible barrier according to the invention, comprising on each side end elements 26 and 27 fixed between two fixed points S1, S2 of the site and the barrier thus assembled fig. 15. For barriers of this type, it is preferable to have at least one module 40 or 41 at one of its ends to benefit from its anti-rollover capability and better yet, to have modular end elements. four-point fixation on each side on a wall or posts anchored to the site.

Les figures 16 et 17 montrent un exemple de profilé 12 de main courante en forme de U inversé comportant deux ailettes 45 faisant fonction de butée de clipage d'un profilé 16 sur lequel le profilé 12 est conçu pour s'engager et se verrouiller par déformation élastique au moyen de deux bossages 46 de clipage sur les parties en pente 47 correspondantes du profilé 16. Ce profilé 16 est aussi en forme de U dont la partie haute 48 des ailes verticales est inclinée en pente vers l'intérieur pour faciliter l'engagement des bossages 46 de clipage sur les angles 47. L'âme 48 est percée, au droit des articulations des branches des éléments modulaires et dans son axe longitudinal, de trous 49 de passage des tiges d'articulation (voir les fig.1 et 17). FIGS. 16 and 17 show an example of an inverted U-shaped rail profile 12 comprising two fins 45 acting as a clipping abutment of a profile 16 on which the profile 12 is designed to engage and lock by deformation resilient by means of two clipping bosses 46 on the corresponding sloping portions 47 of the profile 16. This profile 16 is also U-shaped, the upper portion 48 of the vertical wings is sloped inwardly to facilitate engagement bosses 46 of clipping on the angles 47. The core 48 is pierced, at right angles to the branches of the modular elements and in its longitudinal axis, holes 49 for passage of the articulation rods (see Fig.1 and 17). ).

Les figures 18 et 19 montrent, vus en coupe, des exemples de profilés 20 fig. 18 et son capot 50 fig. 19 (voir fig. 1). Ces profilés sont constitutifs de la branche secondaire 15 des éléments modulaires de barrière. Le profilé 20 est de forme en U dont l'extrémité libre 5 Ides ailes est repliée à angle droit vers l'intérieur puis repliée à nouveau en 52 à angle droit vers le haut en se terminant chacune par un bossage de clipage 53; les angles inférieurs 54 sont soit arrondis soit cassés. Le capot 50 est également en forme de U inversé dont les ailes courtes et amincies 55 se terminent par un bossage de clipage 56 complémentaire à ceux du profilé 20. L'âme 57 du profilé 20 (fig. 18) est percée de trous de passage des barreaux (fig. 20 et 28) qui sont ensuite sertis et, au droit des pivots, comporte un trou poinçonné pour le passage d'un barreau 15 dans lequel passe la tige d'articulation. Figures 18 and 19 show, in section, examples of profiles 20 fig. 18 and its hood 50 fig. 19 (see Fig. 1). These sections constitute the secondary branch 15 of the modular barrier elements. The profile 20 is U-shaped with the free end 5 of the wings bent at right angles inwards and then bent again at 52 at right angles upwards each ending with a clipping boss 53; the lower corners 54 are either rounded or broken. The cover 50 is also inverted U-shaped, the short and thinned wings 55 end with a clipping boss 56 complementary to those of the profile 20. The core 57 of the profile 20 (FIG 18) is pierced with through holes bars (Figures 20 and 28) which are then crimped and, in line with the pivots, comprises a punched hole for the passage of a bar 15 in which the hinge pin passes.

La figure 20 montre la section des barreaux verticaux 17 constituant, avec les profilés 16, 12, 20 et 50, les deux branches principale et secondaire des différents éléments modulaires. Ce profilé 17 est de section rectangulaire aux angles 61 arrondis. Le milieu de ses deux faces intérieures comporte une alvéovis 60 permettant sa fixation entre les profilés haut et bas 16 (fig.23). Figure 20 shows the section of the vertical bars 17 constituting, with the profiles 16, 12, 20 and 50, the two main and secondary branches of the various modular elements. This profile 17 is of rectangular section with 61 rounded corners. The middle of its two inner faces comprises an alveovis 60 allowing its attachment between the high and low profiles 16 (fig.23).

La figure 21 montre le barreau 17 de la fig.20 dans les extrémités supérieure et inférieure duquel on a inséré un palier 64 en matière plastique dans lequel la tige pivote. Figure 21 shows the bar 17 of Fig.20 in the upper and lower ends of which there is inserted a bearing 64 of plastic in which the rod pivots.

La figure 22 montre un exemple, vu en coupe, des pivots de la barrière. On reconnaît les profilés 16 (voir fig.1) des branches 14 et les profilés 20 et 50 des branches 15. Des barreaux 17 (non représentés) sont fixés entre les profilés 16 définissant leur position horizontale; la tige 65 est engagée dans les trous correspondants des profilés, les écrous 66, 67 ayant été mis en place et approchés contre les profilés 16 en même temps ainsi que les rondelles 68 et 69 laissant un léger jeu entre écrous 66,67 et rondelles 68, 69 pour permettre à la branche 15 de pivoter avec douceur sur les paliers 64 de la tige 65. Des rondelles plates 70 et des rondelles indesserrables 71 sont placées sur les extrémités filetées de la tige 65 et les écrous 72 sont bloqués sur leur rondelle immobilisant la tige 65 sur la branche principale. Figure 22 shows an example, seen in section, of the pivots of the barrier. The profiles 16 (see FIG. 1) of the branches 14 and the sections 20 and 50 of the branches 15 are recognized. Bars 17 (not shown) are fixed between the sections 16 defining their horizontal position; the rod 65 is engaged in the corresponding holes of the profiles, the nuts 66, 67 having been put in place and approached against the sections 16 at the same time as well as the washers 68 and 69 leaving a slight clearance between nuts 66, 67 and washers 68 , 69 to allow the limb 15 to pivot smoothly on the bearings 64 of the rod 65. The flat washers 70 and the lock washers 71 are placed on the threaded ends of the rod 65 and the nuts 72 are locked on their immobilizing washer the stem 65 on the main branch.

La figure 23 montre un exemple de fixation d'un barreau 17 entre deux profilés 16 ou 20 de constitution des branches 14 et 15 des divers éléments modulaires. La fixation est effectuée au moyen de quatre vis 75 autotaraudeuses engagées dans les trous de passage des profilés et vissées dans les alvéovis 60 des barreaux. Ce mode de fixation renforce notablement la résistance à la déformation longitudinale de la barrière pendant les manoeuvres d'ouverture et de fermeture. Les barreaux peuvent également être sertis comme il sera montré sur la figure 28. Figure 23 shows an example of fixing a bar 17 between two sections 16 or 20 constituting the branches 14 and 15 of the various modular elements. Fixing is performed by means of four self-tapping screws 75 engaged in the through-holes of the profiles and screwed into the alveovis 60 of the bars. This method of attachment significantly increases the resistance to longitudinal deformation of the barrier during the opening and closing maneuvers. The bars can also be crimped as will be shown in Figure 28.

La figure 24 montre un exemple, vu en coupe, d'un système amovible de patin d'appui au sol monté auprès de chaque pivot extérieur de la barrière de façon à rattraper les dénivellations du site ou les passages de trottoirs. Il comporte un fourreau tubulaire 80 dans lequel coulisse verticalement une tige 81 sur un épaulement 82 et sur un palier inférieur 83. Un patin d'appui 84 est fixé sur l'extrémité inférieure de la tige 81. Un ressort de compression est disposé en appui entre le palier 83 et l'épaulement 82. Un levier 86 de verrouillage, articulé en 87 sur le support du système, comporte un trou légèrement plus grand que le diamètre de la tige de patin, l'arête du trou bloque celui-ci en position haute ou basse poussé par un ressort 88. Le système est monté de façon amovible sur un barreau d'extrémité et en butée sur l'extrémité du profilé inférieur 20. Pour descendre le patin en appui sur le sol, on pousse sur l'extrémité supérieure 89 de la tige 81 dans le sens de la flèche 90 en comprimant le ressort 85, en même temps que l'on débloque le levier auto-bloquant 86 en le poussant vers le bas au travers du trou 91. Pour bloquer le patin au sol, il suffit de relâcher le levier qui se bloque sur la tige 81 sous l'effet du ressort 88. Pour remonter le patin à sa position de repos, on appuie sur le levier 86 ce qui a pour effet de libérer la tige 81 qui remonte en butée sous l'action du ressort 85. Dans les expositions où le sol est recouvert de moquette, les barrières ne sont généralement pas verrouillées, elles n'ont pas de roulettes mais reposent sur des patins plus larges pouvant glisser sur la moquette. FIG. 24 shows an example, seen in section, of a removable ground support pad system mounted at each outer pivot of the barrier so as to make up for the unevenness of the site or the sidewalk passages. It comprises a tubular sheath 80 in which a rod 81 slides vertically on a shoulder 82 and on a lower bearing 83. A bearing pad 84 is fixed on the lower end of the rod 81. A compression spring is disposed in support between the bearing 83 and the shoulder 82. A locking lever 86, articulated at 87 on the support of the system, has a hole slightly larger than the diameter of the shoe pin, the edge of the hole blocks the latter. high or low position pushed by a spring 88. The system is removably mounted on an end bar and abuts on the end of the lower section 20. To lower the pad resting on the ground, it pushes on the upper end 89 of the rod 81 in the direction of the arrow 90 by compressing the spring 85, at the same time that it releases the self-locking lever 86 by pushing down through the hole 91. To lock the pad on the ground, simply release the which sticks on the rod 81 under the effect of the spring 88. To raise the pad to its rest position, is pressed on the lever 86 which has the effect of releasing the rod 81 which rises in abutment under the action 85. In exhibitions where the floor is carpeted, the barriers are generally not locked, they do not have wheels but rest on wider skids that can slide on the carpet.

La figure 25 montre un exemple vu schématiquement de dessus, d'une longue barrière selon l'invention, constituée de plusieurs tronçons 90, 91, 92 à assembler sur le site au moyen de verrous 93. FIG. 25 shows an example diagrammatically seen from above, of a long barrier according to the invention, consisting of several sections 90, 91, 92 to be assembled on the site by means of locks 93.

La figure 26 montre un exemple de moyen de fixation et de verrouillage de deux tronçons de barrière entre eux. La pièce normale 95 de fermeture de l'extrémité de chacun des profilés 16 en vis-à-vis est prolongée vers l'extérieur par une plaque 96 percée d'un gros trou 97. Une plaque de liaison 98 est rendue solidaire de l'une des pièces de fermeture 95 au moyen d'un boulon 99 dont l'écrou 100 est serti par exemple par trois coups de pointeau à 120°. La fixation est assurée par une tige épaulée engagée dans les trous de l'autre pièce 96 et de la plaque 98 cependant qu'un cadenas 102 et engagé dans un trou 103 percé dans l'extrémité de la tige 101 interdisant une ouverture non autorisée. Figure 26 shows an example of means for fixing and locking two barrier sections between them. The normal part 95 closing the end of each of the profiles 16 vis-à-vis is extended outwardly by a plate 96 pierced with a large hole 97. A connecting plate 98 is secured to the one of the closure pieces 95 by means of a bolt 99 whose nut 100 is crimped for example by three needle strokes at 120 °. Fixing is provided by a shouldered rod engaged in the holes of the other piece 96 and the plate 98, however, a padlock 102 and engaged in a hole 103 drilled in the end of the rod 101 prohibiting unauthorized opening.

La figure 27 montre un exemple, vu en élévation, de fixation verrouillable de l'extrémité d'une barrière 105 sur un poteau métallique 106 ancré de façon provisoire ou définitive sur le site. La pièce de fermeture 95 est prise dans une chape 107 dans laquelle la tige 101 est engagée et verrouillée par un cadenas 102. La chape 107 est prolongée par une tige filetée 108 engagée par exemple dans un trou de l'âme 109 du poteau en U ou H ou d'une plaque métallique 109 solidaire d'un mur ou autre. Cette tige 108 est bloquée sur ladite plaque après réglage de la position de la chape par rapport à la barrière au moyen de quatre écrous 110 après interposition de chaque côté de la plaque 109 de rondelles coniques 111 d'amortissement des efforts exercés sur la barrière. Figure 27 shows an example, seen in elevation, lockable fixing of the end of a barrier 105 on a metal post 106 anchored provisionally or permanently on the site. The closure piece 95 is engaged in a yoke 107 in which the rod 101 is engaged and locked by a padlock 102. The yoke 107 is extended by a threaded rod 108 engaged for example in a hole in the web 109 of the U-shaped post or H or a metal plate 109 secured to a wall or the like. This rod 108 is locked on said plate after adjusting the position of the yoke relative to the barrier by means of four nuts 110 after interposition of each side of the plate 109 of conical washers 111 for damping the forces exerted on the barrier.

La figure 28 montre, vu en perpective, le détail de pivotement d'une branche secondaire sur le pivot d'extrémité d'une branche principale des éléments modulaires de la barrière selon l'invention. Les numéros de repère des figures précédentes ont été utilisés pour les mêmes organes. Cette figure permet de mieux comprendre le montage des branches principale et secondaire sur leur pivot. On voit également le montage des barreaux 17 entre les profilés 16 de la branche principale 14 et les profilés 18 sertis en haut et en bas en 115, 116 dans les profilés 20 haut et bas de la branche secondaire 15. Le barreau 15 peut aussi être serti, mais ce n'est pas nécessaire puisqu'il est en butée de chaque côté sur les ailettes correspondantes des profilés 20 et qu'il reçoit deux paliers 64 de la tige pivot 65. Figure 28 shows, seen in perspective, the pivoting detail of a secondary branch on the end pivot of a main branch of the modular elements of the barrier according to the invention. The reference numbers of the preceding figures have been used for the same organs. This figure makes it possible to better understand the assembly of the main and secondary branches on their pivot. We also see the mounting of the bars 17 between the profiles 16 of the main branch 14 and the profiles 18 crimped at the top and bottom 115, 116 in the profiles 20 up and down of the secondary branch 15. The bar 15 can also be crimped, but it is not necessary since it is in abutment on each side on the corresponding fins of the profiles 20 and it receives two bearings 64 of the pivot rod 65.

Les espaces entre les barreaux 17 et 18 de la barrière peuvent être fermés par divers moyens tels que tôle de bardage, tôle ondulée, panneaux en matière plastique opaque, transparente ou translucide, en verre feuilleté ou en alliage léger. Ces moyens de fermeture peuvent être ajourés sauf le verre. Ces divers moyens de fermeture peuvent être insérés dans des joints encastrés dans de petits profilés en U standards en alliage léger, traités anti-corrosion, fixés sur les petits côtés des barreaux. Ces panneaux peuvent recevoir des affichages publicitaires.The spaces between the bars 17 and 18 of the barrier can be closed by various means such as cladding sheet, corrugated sheet, opaque plastic panels, transparent or translucent, laminated glass or light alloy. These closure means may be perforated except the glass. These various closure means can be inserted into seals embedded in small standard U-shaped profiles, anti-corrosion treated, fixed on the short sides of the bars. These panels can receive advertising displays.
