La présente invention est relative à une barrière rétractable apte à occuper successivement deux états, un premier état déplié où la barrière est fonctionnelle et un second état où la barrière est repliée. L'organisation d'événements ponctuels 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. En particulier, l'usage de barrières est souvent nécessaire pour canaliser les mouvements de foule et/ou comme support publicitaire. Les barrières utilisées doivent être suffisamment rigides et résistantes pour supporter une utilisation intensive et être rétractable de manière à occuper un espace réduit lors du stockage. Les barrières rétractables existantes ressemblent généralement à celles utilisées pour les passages à niveau. Les barrières de ce type occupent le même volume à l'état déplié et à l'état replié ce qui ne facilite pas leur stockage.The present invention relates to a retractable barrier capable of successively occupying two states, a first unfolded state where the barrier is functional and a second state where the barrier is folded. The organization of 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. In particular, the use of barriers is often necessary to channel crowd motions and / or as an advertising medium. The barriers used must be sufficiently rigid and resistant to withstand intensive use and be retractable so as to occupy a small space during storage.

Dans toute la description qui suit d'un mode de réalisation d'une barrière rétractable selon l'invention, les termes relatifs tels que « supérieur », « inférieur », « avant », « arrière », « horizontal » et « vertical » sont à interpréter lorsque la barrière rétractable selon l'invention est installée en situation de fonctionnement.Throughout the following description of an embodiment of a retractable barrier according to the invention, the relative terms such as "upper", "lower", "front", "back", "horizontal" and "vertical" are to be interpreted when the retractable barrier according to the invention is installed in an operating situation.
On peut voir sur Fig. 1 une barrière rétractable B selon l'invention. La barrière rétractable B comprend un châssis 1 composé de profilés métalliques de section carrée soudés. Les profilés peuvent être de sections variées et également réalisés à partir de polymères ou de composites, par exemple en utilisant un renfort textile et une résine.We can see on Fig. 1 a retractable barrier B according to the invention. The retractable barrier B comprises a frame 1 composed of welded square section metal sections. The profiles may be of various sections and also made from polymers or composites, for example using a textile reinforcement and a resin.
Le châssis 1 a une forme sensiblement parallélépipédique, chaque arête du parallélépipède étant occupée par un profilé. D'une manière générale, la forme externe du châssis 1 est adaptée à l'environnement de la barrière B.The frame 1 has a substantially parallelepiped shape, each edge of the parallelepiped being occupied by a profile. In general, the external shape of the frame 1 is adapted to the environment of the barrier B.
Des pieds 2, réglables en hauteur, assurent la stabilité de la barrière rétractable B.Feet 2, adjustable in height, ensure the stability of the retractable barrier B.
Deux bobines 3, 4, d'axe horizontal, sont montés à rotation sur le châssis 1 dans un même plan vertical. La bobine 3 est montée au-dessus de la bobine 4. Chaque bobine 3, 4 est constituée d'un moyeu cylindrique solidaire de deux plateaux circulaires.Two coils 3, 4, of horizontal axis, are rotatably mounted on the chassis 1 in the same vertical plane. The coil 3 is mounted above the coil 4. Each coil 3, 4 consists of a cylindrical hub integral with two circular plates.
Chaque bobine 3, 4 est montée à rotation entre deux paliers 3a et 4a. Chaque palier 3a, 4a est monté coulissant sur deux rails 3b, 4b, de section circulaire et fixés au châssis. Un dispositif de serrage non représenté permet d'immobiliser chaque palier 3a, 4a dans la position choisie.Each coil 3, 4 is rotatably mounted between two bearings 3a and 4a. Each bearing 3a, 4a is slidably mounted on two rails 3b, 4b, of circular section and fixed to the frame. A not shown clamping device makes it possible to immobilize each bearing 3a, 4a in the chosen position.
Sur chaque bobine 3, 4 est enroulé un élément semi-rigide 5, 6.On each coil 3, 4 is wound a semi-rigid element 5, 6.
Les éléments semi-rigides 5, 6 se présentent sous la forme de tubes fendus selon une direction longitudinale lorsqu'ils sont déroulés. A l'état enroulé chaque élément semi-rigide 5, 6 se présente sous la forme d'un ruban.The semi-rigid elements 5, 6 are in the form of slit tubes in a longitudinal direction when they are unwound. In the wound state each semi-rigid element 5, 6 is in the form of a ribbon.
Chaque élément semi-rigide 5, 6 comporte une extrémité libre 5a, 6a, déroulée horizontalement.Each semi-rigid element 5, 6 has a free end 5a, 6a, unrolled horizontally.
L'extrémité libre 5a de l'élément supérieur 5 est guidée par un galet 7 monté rotatif par rapport au châssis 1 au-dessus de l'extrémité libre 5a. L'extrémité libre 6a de l'élément inférieur 6 est guidée par un galet 8 monté rotatif par rapport au châssis 1 en dessous de l'extrémité libre 6a. Les galets 7 et 8 ont chacun la forme d'un diabolo, c'est-à-dire de deux troncs de cône opposés par le sommet. Les extrémités libres 5a et 6a sont reliées par une poignée 9. La poignée 9 permet d'effectuer une traction sur les éléments 5 et 6 et rigidifie l'ensemble.The free end 5a of the upper member 5 is guided by a roller 7 rotatably mounted relative to the frame 1 above the free end 5a. The free end 6a of the lower member 6 is guided by a roller 8 rotatably mounted relative to the frame 1 below the free end 6a. The rollers 7 and 8 each have the form of a diabolo, that is to say two truncated cones opposed by the top. The free ends 5a and 6a are connected by a handle 9. The handle 9 makes it possible to pull on the elements 5 and 6 and stiffens the assembly.
L'élément semi-rigide supérieur 5 est enroulé de telle sorte qu'une fois déroulé, la fente 5b créée lorsque l'élément 5 se présente sous la forme d'un tube fendu, est placée en regard de l'élément semi-rigide inférieur 6.The upper semi-rigid element 5 is wound so that once unwound, the slot 5b created when the element 5 is in the form of a split tube, is placed opposite the semi-rigid element lower 6.
De manière similaire, l'élément semi-rigide inférieur 6 est enroulé de telle sorte qu'une fois déroulé, la fente 6b créée lorsque l'élément 6 se présente sous la forme d'un tube fendu, est placée en regard de l'élément semi-rigide supérieur 5. Une bobine ou tambour 10 montée rotative autour d'un axe vertical par rapport au châssis 1 supporte un rideau enroulable 1 1.Similarly, the lower semi-rigid element 6 is wound so that once unwound, the slot 6b created when the element 6 is in the form of a split tube, is placed opposite the upper semi-rigid element 5. A coil or drum 10 rotatably mounted about a vertical axis relative to the frame 1 supports a roll-up curtain 11.
Le rideau 1 1 peut être plein et obtenu à partir d'une matière flexible mais il peut également être composé de barreaux verticaux. Le support publicitaire peut être en matière souple ou semi-rigide. L'extrémité libre 1 1 a du rideau 1 1 , solidaire de la poignée 9, est guidée par un rouleau 12 d'axe vertical, monté rotatif par rapport au châssis 1 , et est pincée dans les fentes 5b, 6b des extrémités libres 5a, 6a des éléments semi-rigides 5, 6. Le rideau 11 , guidé par le rouleau 12, peut être levé ou abaissé pour être correctement positionné par rapport aux fentes 5b et 6b.The curtain 11 can be solid and obtained from a flexible material but it can also be composed of vertical bars. The advertising medium may be flexible or semi-rigid material. The free end January 1 of the curtain January 1, integral with the handle 9, is guided by a roller 12 of vertical axis, rotatably mounted relative to the frame 1, and is clamped in the slots 5b, 6b of the free ends 5a , 6a semi-rigid elements 5, 6. The curtain 11, guided by the roller 12, can be lifted or lowered to be properly positioned relative to slots 5b and 6b.
Le bord inférieur 11 c du rideau 11 est pincé dans la fente 6b de l'élément inférieur 6 tandis que le bord supérieur 1 1 b du rideau 1 1 est pincé dans la fente 5b de l'élément supérieur 5. Un pied 13 est solidaire de la poignée 9 et permet aux extrémités libres 5a, 6a de rester horizontales.The lower edge 11c of the curtain 11 is clamped in the slot 6b of the lower member 6 while the upper edge 11b of the curtain 11 is pinched in the slot 5b of the upper member 5. A foot 13 is secured of the handle 9 and allows the free ends 5a, 6a to remain horizontal.
En variante, le rideau 1 1 peut être utilisé comme support publicitaire et imprimé dans ce but.Alternatively, the curtain 1 1 can be used as an advertising medium and printed for this purpose.
Le fonctionnement de la barrière B est le suivant. La barrière B est stockée à l'état replié. Elle peut aussi être solidaire d'un élément urbain fixe ou mobile. Dans cette position, les éléments semi- rigides 5, 6 sont presque totalement enroulés sur les bobines 3 et 4. Le rideau 1 1 est également presque totalement enroulé sur la bobine 10. Les extrémités libres 5a et 6a ainsi que les fentes 5b et 6b ont une longueur réduite. Néanmoins les extrémités libres 5a et 6a restent reliées par la poignée 9. De même l'extrémité libre 1 1 a du rideau 11 est pincée dans les fentes 5b et 6b.The operation of barrier B is as follows. Barrier B is stored in the folded state. It can also be attached to a fixed or mobile urban element. In this position, the semi-rigid elements 5, 6 are almost completely wound on the coils 3 and 4. The curtain 11 is also almost completely wound on the spool 10. The free ends 5a and 6a and the slots 5b and 6b have a reduced length. However, the free ends 5a and 6a remain connected by the handle 9. Similarly, the free end 11a of the curtain 11 is pinched in the slots 5b and 6b.
Lorsqu'un opérateur désire déployer la barrière B, il tire sur la poignée 9 dans une direction opposée au châssis 1. Cette action entraine le déroulement des éléments semi-rigides 5, 6 et du rideau 1 1.When an operator wishes to deploy the barrier B, he pulls the handle 9 in a direction opposite to the frame 1. This action causes the unwinding of the semi-rigid elements 5, 6 and the curtain January 1.
Au fur et à mesure que les éléments semi-rigides 5, 6 se déroulent, ils changent d'état et passe de l'état de ruban à celui de tube rigide.As the semi-rigid elements 5, 6 unfurl, they change state and move from the ribbon state to the rigid tube state.
La longueur des fentes 5b et 6b augmente parallèlement au déroulement des éléments semi-rigides 5, 6 ce qui permet le pincement continu du rideau 1 1.The length of the slots 5b and 6b increases parallel to the unwinding of the semi-rigid elements 5, 6 which allows the continuous nipping of the curtain January 1.
Lorsque la barrière B est suffisamment déroulée, la poignée 9 est posée sur le sol par l'intermédiaire du pied 13.When the barrier B is sufficiently unwound, the handle 9 is placed on the ground via the foot 13.
De nombreuses utilisations et variantes sont possibles.Many uses and variants are possible.
Pour délimiter un passage, il est possible d'utiliser un seul ou plusieurs éléments rétractables selon la largeur que l'on souhaite donner à la barrière formée par le ou les éléments rétractables.To delimit a passage, it is possible to use one or more retractable elements according to the width that is to be given to the barrier formed by the retractable element or elements.
Le châssis, que l'on peut qualifier également de borne de stockage, peut comporter plusieurs barrières de manière à délimiter l'espace dans plusieurs directions. Dans un châssis parallélépipédique, on peut envisager d'installer quatre paires de deux éléments rétractables. Une fois déroulés, les éléments rétractables ainsi agencés forment un parallélépipède de longueur variable.The frame, which can also be described as a storage terminal, may include several barriers so as to delimit the space in several directions. In a parallelepiped frame, it is conceivable to install four pairs of two retractable elements. Once unrolled, the retractable elements thus arranged form a parallelepiped of variable length.
Il est également possible d'envisager un rideau comportant un rayon de courbure et qui ne serait pas plan en fonction des applications.It is also possible to envisage a curtain with a radius curvature and that would not be plan according to the applications.
Les éléments semi-rigides 5, 6 sont produits de la manière suivante.The semi-rigid elements 5, 6 are produced as follows.
Un renfort textile (fibre, fil ou multi-filament minéral/céramique, naturel, thermodurcissable ou thermoplastique) est pré-imprégné avec une résine thermoplastique, et/ou associé à d'autres fibres, fils ou multi-filaments thermoplastiques, avant d'être mis en forme tubulaire au moyen d'un procédé de tissage, de tressage, de sur-tressage, de tricotage ou de dépose filamentaire.A textile reinforcement (fiber, yarn or multi-filament mineral / ceramic, natural, thermosetting or thermoplastic) is pre-impregnated with a thermoplastic resin, and / or associated with other fibers, son or multi-filaments thermoplastic, before be tubular shaped by a process of weaving, braiding, over-braiding, knitting or filamentary laying.
Le renfort tubulaire peut être directement fabriqué sur un moule ayant une forme tubulaire ou bien il peut être préfabriqué puis drapé sur un moule ayant une forme tubulaire. Il est possible de draper plusieurs couches sur le moule tubulaire.The tubular reinforcement may be directly manufactured on a mold having a tubular shape or it may be prefabricated and then draped over a mold having a tubular shape. It is possible to drape several layers on the tubular mold.
L'ensemble moule tubulaire et fibres entrecroisées est alors thermoformé par cuisson de la résine. Après refroidissement, la résine thermoplastique durcie et lie ainsi le renfort textile selon la forme du moule tubulaire. Ensuite le tube obtenu est démoulé. The tubular mold assembly and interwoven fibers is then thermoformed by baking the resin. After cooling, the thermoplastic resin cures and thus binds the textile reinforcement according to the shape of the tubular mold. Then the tube obtained is demolded.
