Séparateur et barrière de protection ou de délimitation, par exemple pour voie de circulation automobile.Separator and barrier for protection or delimitation, for example for automobile traffic lane.
La présente invention concerne un séparateur pour voie de circulation automobile. Elle vise aussi les barrières de protection réalisées au moyen de la juxtaposition et de la liaison articulée, les uns à la suite des autres, d'une pluralité de tels séparateurs.The present invention relates to a separator for an automobile traffic lane. It also relates to the protective barriers produced by means of the juxtaposition and the articulated connection, one after the other, of a plurality of such separators.
Un exemple d'application particulièrement avantageux, bien que non exclusif, des séparateurs et barrières selon l'invention, est l'équipement des pistes de karting, ou de motos, ou des circuits automobiles, en vue d'assurer la sécurité des concurrents et des spectateurs. Une autre application intéressante est la délimitation ou la séparation des voies de circulation routières ou autoroutières, des aires de stationnement, des quais, des pistes d'aérodromes, etc.An example of a particularly advantageous, although not exclusive, application of the separators and barriers according to the invention is the equipment of go-kart tracks, or of motorcycles, or automobile circuits, in order to ensure the safety of competitors and spectators. Another interesting application is the delimitation or separation of road or motorway traffic lanes, parking areas, quays, aerodrome runways, etc.
On a proposé, dans le document FR-A-2.598.484, une barrière de séparation ou de sécurité constituée d'une pluralité de plots massifs, à peine plus longs que larges, juxtaposés les uns à la suite des autres et reliés par au moins un câble les traversant longitudinalement. Selon un mode d'exécution, ces plots comportent, à leurs extrémités, des surfaces de forme cylindrique, respectivement convexe et concave, de même rayon de courbure, permettant de juxtaposer deux plots, de façon que la surface convexe de l'un puisse coopérer avec la surface concave de l'autre, en permettant une rotation d'un plot par rapport à l'autre. Les barrières réalisées de la sorte ont des qualités d'amortissement des chocs quasiment nulles et ne présentent aucune élasticité. D'autre part, lorsqu'un véhicule heurte violemment la barrière et provoque l'éclatement d'un ou plusieurs plots, le câble métallique assurant la liaison de ces derniers peut constituer un élément coupant extrêmement dangereux.Document FR-A-2,598,484 has proposed a separation or security barrier made up of a plurality of solid studs, barely longer than wide, juxtaposed one after the other and connected by minus one cable passing through them longitudinally. According to one embodiment, these studs comprise, at their ends, surfaces of cylindrical shape, respectively convex and concave, with the same radius of curvature, making it possible to juxtapose two studs, so that the convex surface of one can cooperate with the concave surface of the other, allowing rotation of one stud relative to the other. The barriers produced in this way have almost zero shock absorption qualities and have no elasticity. On the other hand, when a vehicle violently strikes the barrier and causes the bursting of one or more studs, the metal cable ensuring the connection of the latter can constitute an extremely dangerous cutting element.
Dans le document FR-A-2.425.503 est décrite une barrière de sécurité constituée d'une pluralité de modules cylindriques disposés les uns à la suite et à distance des autres et reliés par des câbles ou filins d'acier. Ces modules comprennent une armature cylindrique souple formée par des pneus usagés empilés recouverts par un revêtement extérieur et remplis par un matériau tel que ciment, plâtre ou mortier (FR- A-2.314.303), constituant le module proprement dit et coulé à l'intérieur de ladite armature. Cette barrière procure des qualités médiocres d'amortissement des chocs bien que meilleures que celles obtenues avec la barrière décrite dans le document FR- A-2.598.484. Par contre, l'utilisation de câbles ou filins d'acier pour relier les modules entre eux engendre un sérieux danger pour les occupants des véhicules qui viennent percuter ces câbles, le danger se trouvant aggravé par l'espacement ménagé entre lesdits modules.In document FR-A-2,425,503 is described a safety barrier made up of a plurality of cylindrical modules arranged one after the other and at a distance from each other and connected by cables or steel ropes. These modules include a flexible cylindrical frame formed by stacked used tires covered by an external coating and filled with a material such as cement, plaster or mortar (FR-A-2,314,303), constituting the module proper and poured in. interior of said frame. This barrier provides poor shock absorption qualities although better than those obtained with the barrier described in document FR-A-2,598,484. On the other hand, the use of cables or steel cables to connect the modules together creates a serious danger for the occupants of the vehicles which come into collision with these cables, the danger being aggravated by the spacing provided between said modules.
On a décrit dans le document EP 0 441 109 A2, une barrière de séparation de trafic possédant des propriétés de dissipation de l'énergie de collision comprenant une pluralité d'éléments dissipateurs alignés de forme cylindrique ou elliptique en coupe transversale et réalisés en caoutchouc cellulaire ou autre matériau élastique cellulaire, chacun desdits éléments possédant un guide transversal pour le passage d'un unique câble d'ancrage qui est fixé, d'une part, en un point situé en avant du premier desdits éléments dissipateurs et, d'autre part, en un point situé en arrière du dernier de ceux- ci.EP 0 441 109 A2 describes a traffic separation barrier having properties for dissipating collision energy, comprising a plurality of dissipating elements aligned in cylindrical or elliptical shape in cross section and made of cellular rubber or other elastic cellular material, each of said elements having a transverse guide for the passage of a single anchoring cable which is fixed, on the one hand, at a point situated in front of the first of said dissipating elements and, on the other hand , at a point behind the last of these.
Outre leur prix de revient élevé et leur montage sur un socle ou soubassement en béton armé excluant leur utilisation en bordure de piste de karting ou de circuits automobiles, les barrières réalisées à l'aide d'éléments de section circulaire ou elliptique distants les uns des autres, présentent des renfoncements constituant autant d'emplacements d'impact privilégiés favorisant le défoncement de la barrière, tandis que la liaison des éléments au moyen d'un câble unique rend possible un pivotement de ces derniers autour dudit câble, de sorte que leur stabilité est mal assurée, tandis que ce câble unique représente un danger pour les conducteurs qui viendraient le heurter.In addition to their high cost price and their mounting on a reinforced concrete base or base excluding their use on the edge of a go-kart track or automobile circuits, the barriers made using elements of circular or elliptical section distant from each other others have recesses constituting as many privileged impact locations favoring the knockout of the barrier, while the connection of the elements by means of a single cable makes it possible for them to pivot around said cable, so that their stability is poorly insured, while this single cable represents a danger for the conductors who come to strike it.
Les plots décrits dans les documents susmentionnés présentent également l'inconvénient d'avoir une longueur (ou un diamètre) réduite de sorte que les véhicules heurtant la barrière ont tendance à s'encastrer entre deux plots déplacés et écartés par le choc.The studs described in the aforementioned documents also have the disadvantage of having a reduced length (or diameter) so that the vehicles striking the barrier tend to become embedded between two studs displaced and spaced apart by the impact.
En raison de leurs inconvénients précédemment soulignés, les barrières exécutées conformément aux documents de l'état de la technique, sont à proscrire dans certaines applications telles que les circuits de Karting, de motos ou similaires.Because of their drawbacks previously outlined, the barriers executed in accordance with the documents of the state of the art are to be avoided in certain applications such as go-kart circuits, motorcycles or the like.
L'invention vise notamment à remédier à ces inconvénients. - 3 -The invention aims in particular to remedy these drawbacks. - 3 -
Selon une première disposition caractéristique, l'élément séparateur selon l'invention, présente une section horizontale oblongue et comporte une extrémité cylindro-convexe et une extrémité cylindro-concave destinées à former une emboîture articulée ou articulation cylindrique avec l'extrémité cylindro-concave et avec l'extrémité cylindro-convexe d'un élément séparateur voisin identique ou semblable, respectivement, ledit élément séparateur comportant au moins un passage longitudinal permettant sa traversée par au moins un lien souple permettant de le relier à un ensemble d'éléments séparateurs identiques ou semblables pour la réalisation d'une barrière articulée de protection ou de délimitation de voies de circulation., cet élément séparateur étant constitué par un corps creux et vide apte à renfermer un important volume d'air formant amortisseur.According to a first characteristic arrangement, the separating element according to the invention has an oblong horizontal section and comprises a cylindro-convex end and a cylindro-concave end intended to form an articulated socket or cylindrical articulation with the cylindro-concave end and with the cylindro-convex end of an identical or similar neighboring separating element, respectively, said separating element comprising at least one longitudinal passage allowing its crossing by at least one flexible link making it possible to connect it to a set of identical separating elements or similar for the realization of an articulated barrier for protection or delimitation of traffic lanes., this separating element being constituted by a hollow and empty body capable of enclosing a large volume of air forming a shock absorber.
Grâce à ce séparateur, il est possible de réaliser des barrières de protection compactes ne présentant ni renfoncement susceptible de créer un point de faiblesse dans lesdites barrières, ni partie saillante pouvant constituer un danger. D'autre part, le lien souple assurant l'assemblage d'une pluralité de séparateurs se trouve totalement noyé dans la file de séparateurs, de sorte qu'il ne présente aucun danger pour les conducteurs. En outre, le séparateur creux et vide assure une bonne dissipation de l'énergie de collision et, par conséquent, un très bon amortissement des chocs.Thanks to this separator, it is possible to produce compact protective barriers having neither recess capable of creating a point of weakness in said barriers, nor projecting part which may constitute a danger. On the other hand, the flexible link ensuring the assembly of a plurality of separators is completely embedded in the line of separators, so that it presents no danger to the conductors. In addition, the hollow and empty separator ensures good dissipation of collision energy and, therefore, very good shock absorption.
Selon une autre disposition caractéristique, les extrémités du séparateur selon l'invention comportent au moins deux passages superposés, distants l'un de l'autre et autorisant sa traversée par deux liens souples superposés permettant de le relier à un ensemble de séparateurs identiques ou semblables pour la réalisation d'une barrière articulée.According to another characteristic arrangement, the ends of the separator according to the invention comprise at least two superimposed passages, distant from each other and allowing its crossing by two flexible superimposed links making it possible to connect it to a set of identical or similar separators for the realization of an articulated barrier.
Grâce à cette disposition, la paire de liens souples permet de s'opposer au pivotement des éléments séparateurs dont la stabilité est ainsi bien assurée. En outre, la file de séparateurs liés au moyen de deux liens souples superposés offre une bonne résistance à l'éventrement.Thanks to this arrangement, the pair of flexible links makes it possible to oppose the pivoting of the separating elements, the stability of which is thus well ensured. In addition, the line of separators linked by means of two superimposed flexible links offers good resistance to eventing.
Selon une autre disposition caractéristique, le lien souple ou chaque lien souple reliant les séparateurs entre eux est constitué par une sangle plate, par exemple exécutée en fibres ou textiles synthétiques, cette bande souple étant disposée de sorte que sa largeur se trouve placée dans un plan vertical ou sensiblement vertical. Grâce à cette disposition, les liens souples et larges reliant les éléments séparateurs ne présentent aucun danger pour les conducteurs des véhicules qui percutent la barrière. En effet, ces liens se comportent comme des glissières de sécurité en cas d'écartement ou de defoncement des éléments séparateurs et ils sont eux-mêmes dotés d'une élasticité naturelle contribuant à l'amortissement des chocs.According to another characteristic arrangement, the flexible link or each flexible link connecting the separators to each other consists of a flat strap, for example made of synthetic fibers or textiles, this flexible band being arranged so that its width is placed in a plane vertical or substantially vertical. Thanks to this arrangement, the flexible and wide links connecting the separating elements do not present any danger to the drivers of vehicles striking the barrier. Indeed, these links behave like crash barriers in the event of separation or breakage of the separating elements and they are themselves endowed with a natural elasticity contributing to shock absorption.
Les buts, caractéristiques et avantages ci-dessus, et d'autres encore, ressortiront mieux de la description qui suit et des dessins annexés dans lesquels :The aims, characteristics and advantages above, and others still, will emerge more clearly from the description which follows and from the appended drawings in which:

La figure 6 est une vue de dessus montrant une barrière courbe exécutée à l'aide de séparateurs selon l'invention.FIG. 6 is a top view showing a curved barrier executed using separators according to the invention.
On se reporte auxdits dessins pour décrire un exemple de réalisation avantageux, quoique nullement limitatif, d'un élément séparateur et d'une barrière de protection ou de délimitation réalisés selon l'invention.Reference is made to said drawings to describe an advantageous, although in no way limiting, embodiment of a separating element and of a protective or delimiting barrier produced according to the invention.
Cet élément séparateur 1 est avantageusement réalisé en matière plastique telle qu'un polymère thermoplastique, par exemple en polyéthylène haute densité, par la mise en œuvre d'une technique de moulage par rotation ou rotomoulage, de sorte à présenter, à la fois, la rigidité souhaitable et une bonne résistance au choc.This separating element 1 is advantageously made of plastic material such as a thermoplastic polymer, for example high density polyethylene, by the implementation of a rotational or rotational molding technique, so as to present, at the same time, the desirable rigidity and good impact resistance.
Selon une première disposition caractéristique de l'invention, ce séparateur se présente sous la forme d'un corps creux, homogène, et vide, comportant une section horizontale oblongue. De manière avantageuse, ses bases supérieure et inférieure comportent une large nervure centrale oblongue 2, de sorte à renforcer sa rigidité et sa résistance aux chocs. Le matelas d'air emprisonné à l'intérieur de ce corps et la relative souplesse de ses parois latérales, constituent un dispositif efficace d'amortissement des chocs.According to a first characteristic arrangement of the invention, this separator is in the form of a hollow, homogeneous and empty body, comprising an oblong horizontal section. Advantageously, its upper and lower bases have a large oblong central rib 2, so as to reinforce its rigidity and its impact resistance. The air mattress trapped inside this body and the relative flexibility of its side walls constitute an effective shock absorption device.
Selon une autre disposition caractéristique, le séparateur 1 selon l'invention présente une longueur L au moins deux fois supérieure à sa largeur I et, par exemple une longueur deux fois et demi supérieure à sa largeur, soit : L = I x 2,5.According to another characteristic arrangement, the separator 1 according to the invention has a length L at least twice greater than its width I and, for example a length two and a half times greater than its width, ie: L = I x 2.5 .
Ce séparateur présente, par exemple, une longueur L de l'ordre de 100 cm, une largeur I de l'ordre de 40 cm et une hauteur H de l'ordre de 50 cm.This separator has, for example, a length L of the order of 100 cm, a width I of the order of 40 cm and a height H of the order of 50 cm.
Ces dimensions ont notamment pour avantages de permettre une manipulation aisée des éléments séparateurs par les installateurs en raison de leur poids réduit, de présenter une surface latérale de retenue des véhicules relativement importante, la création d'un matelas d'air volumineux constituant un amortisseur de chocs efficace et la création d'une distance suffisante entre leurs parois latérales contribuant à la résistance au defoncement.These dimensions have in particular the advantages of allowing easy handling of the separating elements by the installers due to their reduced weight, of presenting a relatively large lateral restraint surface of the vehicles, the creation of a bulky air mattress constituting a shock absorber of effective shocks and the creation of a sufficient distance between their side walls contributing to resistance to knocking.
Le séparateur comporte une extrémité cylindro-convexe 4 et une extrémité cylindro concave 5, présentant un rayon identique, raccordées par deux parties latérales planes et parallèles 3. Le diamètre des cylindres définis par les extrémités 4 et 5 des éléments séparateurs correspond à la largeur de ces derniers.The separator has a cylindro-convex end 4 and a concave cylindro end 5, having an identical radius, connected by two flat and parallel lateral parts 3. The diameter of the cylinders defined by the ends 4 and 5 of the separating elements corresponds to the width of these latter.
De la sorte, il est possible d'emboîter une pluralité de séparateurs identiques ou semblables 1A, 1 B, 1 C, 1 D 1 N, les uns à la suite des autres, pour constituer une barrière de délimitation ou de protection, les extrémités cylindro-convexe 4 et cylindro- concave 5 de chaque séparateur intermédiaire formant, ainsi, une emboîture articulée ou articulation cylindrique avec l'extrémité cylindro-concave et avec l'extrémité cylindro- convexe, respectivement, des deux séparateurs identiques ou semblables entre lesquels il se trouve placé.In this way, it is possible to fit a plurality of identical or similar separators 1A, 1 B, 1 C, 1 D 1 N, one after the other, to constitute a delimitation or protection barrier, the ends cylindro-convex 4 and cylindro-concave 5 of each intermediate separator thus forming an articulated socket or cylindrical articulation with the cylindro-concave end and with the cylindro-convex end, respectively, of the two identical or similar separators between which it is placed.
Chaque extrémité convexe ou concave du séparateur ainsi conformé comporte au moins un orifice ou passage 6, d'axe horizontal, permettant sa traversée par un lien souple 7, permettant de le relier à un ensemble de séparateurs identiques ou semblables emboîtés les uns à la suite des autres, pour la réalisation d'une barrière de délimitation ou de protection. - 6 -Each convex or concave end of the separator thus shaped comprises at least one orifice or passage 6, of horizontal axis, allowing its crossing by a flexible link 7, making it possible to connect it to a set of identical or similar separators nested one after the other others, for the creation of a delimitation or protection barrier. - 6 -
De manière avantageuse, chaque extrémité de l'élément séparateur selon l'invention comporte au moins deux orifices ou passages superposés 6 séparés, par exemple, par une distance de l'ordre de 20 cm, et disposés dans le plan vertical médian P-P dudit séparateur. Ces passages superposés autorisent la traversée du séparateur par deux liens souples superposés 7 permettant de le relier à un ensemble de séparateurs identiques ou semblables.Advantageously, each end of the separating element according to the invention comprises at least two superposed orifices or passages 6 separated, for example, by a distance of the order of 20 cm, and arranged in the vertical median plane PP of said separator . These superimposed passages allow the crossing of the separator by two superimposed flexible links 7 making it possible to connect it to a set of identical or similar separators.
Les passages supérieur et inférieur 6 peuvent être disposés à égale distance des faces supérieure et inférieure, respectivement, du séparateur qui est ainsi réversible.The upper and lower passages 6 can be arranged at equal distance from the upper and lower faces, respectively, of the separator which is thus reversible.
On comprend que lorsqu'un véhicule percute un séparateur, il se produit, outre un glissement de ce dernier sur le sol, une compression du matelas d'air renfermé dans ledit séparateur qui remplit ainsi le rôle d'un amortisseur, l'éclatement du séparateur percuté étant évité par la prévision des orifices 6 de passage des sangles 7 permettant un échappement d'air.It is understood that when a vehicle strikes a separator, it occurs, in addition to a sliding of the latter on the ground, a compression of the air mattress enclosed in said separator which thus fulfills the role of a damper, the bursting of the impacted separator being avoided by the provision of orifices 6 for passage of the straps 7 allowing an air escape.
On conçoit également que pour réaliser une barrière de protection, il suffit d'abouter et d'emboîter, les uns à la suite des autres, une pluralité de séparateurs 1 , et de relier ces derniers au moyen de liens souples 7 traversant leurs passages superposés 6 (figure 5). Les extrémités de ces liens peuvent être fixées à des organes fixes ancrés dans le sol ou à des organes de butées élastiques ou non, prenant appui contre les surfaces d'extrémité des éléments terminaux 1A, 1 N, de l'enfilade de séparateurs.It is also conceivable that to produce a protective barrier, it suffices to abut and nest, one after the other, a plurality of separators 1, and to connect the latter by means of flexible links 7 passing through their superimposed passages 6 (Figure 5). The ends of these links can be fixed to fixed members anchored in the ground or to elastic or non-elastic stop members, bearing against the end surfaces of the terminal elements 1A, 1 N, of the row of separators.
Selon une autre importante disposition caractéristique de l'invention, les liens souples 7 sont constitués par des sangles ou bandes plates de préférence exécutées en fibres ou textiles synthétiques tels que, par exemple, polyamides, polyesters ou autres. De telles bandes plates du type sangle de levage peuvent avantageusement présenter une largeur de l'ordre de 50 mm.According to another important arrangement characteristic of the invention, the flexible links 7 are constituted by straps or flat strips preferably made of synthetic fibers or textiles such as, for example, polyamides, polyesters or others. Such flat bands of the lifting strap type can advantageously have a width of the order of 50 mm.
Ces bandes plates dotées d'une certaine capacité d'étirement sous une importante force de traction, sont disposées de sorte que leur largeur se trouve placée dans un plan vertical ou sensiblement vertical, comme le montre la figure 1.These flat strips, which have a certain capacity for stretching under a large tensile force, are arranged so that their width is placed in a vertical or substantially vertical plane, as shown in FIG. 1.
Grâce à la jonction des éléments séparateurs au moyen d'une articulation cylindrique ou genou, ces derniers peuvent avoir des inclinaisons variées les uns par rapport aux autres, de sorte qu'il est possible de monter rapidement des barrières de - 7 -Thanks to the junction of the separating elements by means of a cylindrical or knee joint, the latter can have various inclinations with respect to each other, so that it is possible to quickly mount barriers of - 7 -
protection rectilignes ou courbes ayant des rayons plus ou moins courts, en fonction du tracé des pistes ou circuits. straight or curved protection with shorter or shorter radii, depending on the layout of the tracks or circuits.
