Description

Domaine de l'inventionField of the invention

La présente invention concerne un bras destiné au montage d'un système de protection spécifique pour motocyclistes sur les barrières de sécurité à deux ondes (appelées par la suite, barrières bionde) qui sont installées sur les voies de circulation routières comme moyen de retenue des véhicules lorsqu'ils quittent leur trajectoire et tendent à sortir de la chaussée.The present invention relates to an arm for mounting a specific protection system for motorcyclists on the two-wave safety barriers (hereinafter referred to as bionde barriers) which are installed on the road traffic lanes as a means of retaining vehicles. when they leave their path and tend to exit the road.

Etat de la techniqueState of the art

On sait que les barrières de sécurité bionde non seulement n'offrent pas une sécurité suffisante pour les motocyclistes, mais constituent aussi, dans une grande partie des cas, un élément de risque supplémentaire pour leur intégrité physique.It is known that bionde safety barriers not only do not provide sufficient safety for motorcyclists, but also, in a large part of the cases, constitute an additional element of risk for their physical integrity.

Ceci vient du fait que les barrières bionde sont soutenues sur des poteaux et à une hauteur qui, bien qu'elle permet une retenue très efficace des véhicules de tourisme, laisse en dessous de la barrière un espace suffisant pour le passage du corps d'une personne qui glisse sur le sol de la chaussée.This is because the bionde barriers are supported on poles and at a height which, although it allows for a very effective restraint of passenger vehicles, leaves enough space for the passage of the body of a vehicle below the barrier. nobody slipping on the floor of the roadway.

Dans l'immense majorité des cas, cette situation se produit lorsqu'un motocycliste est éjecté de sa motocyclette. Quand la trajectoire de glissement du motocycliste passe entre deux des poteaux de la barrière bionde, il se peut que le corps vienne heurter l'élément externe à la voie par rapport auquel on souhaite exercer la retenue au moyen de la barrière bionde, par exemple, un arbre ; ou bien il se peut que le corps tombe dans un précipice, ce que l'on souhaitait éviter avec ladite barrière bionde.In the vast majority of cases, this situation occurs when a motorcyclist is ejected from his motorcycle. When the motorcyclist's glide path passes between two of the bionde barrier poles, the body may come into contact with the outer member of the track with respect to which it is desired to restrain using the bionde barrier, for example a tree ; or it may be that the body falls into a precipice, which one wished to avoid with said barrier bionde.

Au contraire, quand la trajectoire est dirigée vers un des poteaux de soutien, le premier impact est contre le poteau et, étant donné l'absence de contrôle de la position que prend le corps éjecté, cet impact peut avoir lieu avec n'importe quelle partie du corps (jambes, tête, tronc). Dans tous les cas, il est très fréquent que le résultat est une mort instantanée, une amputation des extrémités, des lésions médullaires qui peuvent aboutir par exemple à une hémiplégie ou à une paraplégie.On the contrary, when the trajectory is directed towards one of the support posts, the first impact is against the post and, given the absence of control of the position taken by the ejected body, this impact can take place with any part of the body (legs, head, trunk). In all cases, it is very common that the result is instantaneous death, amputation of the extremities, medullary lesions which may lead, for example, to hemiplegia or paraplegia.

Les différentes solutions dans ce domaine ont comme perspective de fournir des compléments de sécurité qui peuvent être couplés aux barrières bionde déjà installées, ce qui permet d'éviter le remplacement de la très grande quantité de kilomètres déjà installés.The various solutions in this field have as a perspective to provide security complements that can be coupled with the barriers bionde already installed, which avoids the replacement of the very large amount of kilometers already installed.

Exposé de l'invention et avantagesPresentation of the invention and advantages

Face à cet état de choses, l'objet de l'invention est un bras d'ancrage qui est destiné à faciliter le couplage, dans des barrières de sécurité bionde déjà installées, d'un élément de sécurité supplémentaire particulièrement destiné à la protection des motocyclistes.In view of this state of affairs, the object of the invention is an anchoring arm which is intended to facilitate the coupling, in already installed bionde safety barriers, of an additional safety element particularly intended for the protection of motorcyclists.

Selon l'invention, ce bras d'ancrage comprend une platine qui a un profil déterminé par trois sections qui sont reliées par deux cassures et qui, conformément à leur disposition opérationnelle, sont une section supérieure, une section intermédiaire et une section inférieure, telles que les sections supérieure et intermédiaire sont reliées au moyen d'une première cassure ayant un angle supérieur à 270°, tandis que les sections intermédi aire et inférieure sont reliées au moyen d'une seconde cassure qui est réalisée dans le sens opposé à celui de ladite première cassure et avec un angle supérieur à celui de ladite première cassure, la section supérieure étant adossée à la face oblique et descendante vers l'arrière d'un séparateur au moyen duquel la barrière de sécurité à deux ondes, ou barrière bionde, est ancrée à chaque poteau de soutien de celle-ci, une encoche supérieure et une encoche inférieure s'ouvrant à l'horizontale sur un des bords latéraux de cette section supérieure, l'encoche supérieure coïncidant avec un trou se trouvant sur la face du séparateur pour une première vis d'ancrage adaptée au montage de la barrière bionde, l'encoche inférieure recevant en son sein l'épaisseur d'une paroi inférieure horizontale du séparateur, la section intermédiaire étant inclinée de façon ascendante vers l'arrière, positionnant la seconde cassure à une distance en rotation adéquate en dessous de ladite paroi inférieure horizontale du séparateur, et la section inférieure s'étendant de façon oblique descendante vers l'avant et possédant une fenêtre verticale pour une seconde vis d'ancrage disposée à travers une fenêtre horizontale pratiquée dans une jupe de sécurité qui s'étend parallèlement à la barrière bionde, couvrant sur sa majeure partie la hauteur entre celle-ci et le sol ; dans cet agencement, dans la position opérationnelle de la platine, la section inférieure est dans une position oblique descendante qui s'étend vers l'avant en formant un angle de 10° par rapport à la verticale.According to the invention, this anchor arm comprises a plate which has a profile determined by three sections which are connected by two breaks and which, according to their operational disposition, are an upper section, an intermediate section and a lower section, such that the upper and intermediate sections are connected by means of a first break having an angle greater than 270 °, while the intermediate and lower sections are connected by means of a second break which is made in the opposite direction to that of said first break and at an angle greater than that of said first break, the upper section being backed to the oblique and downward facing side of a separator by means of which the two-wave safety barrier, or bionde barrier, is anchored to each support pole thereof, an upper notch and a lower notch opening horizontally on one of the edges of said upper section, the upper notch coinciding with a hole on the face of the separator for a first anchor screw adapted to the mounting of the bionde barrier, the lower notch receiving within it the thickness of a horizontal bottom wall of the separator, the intermediate section being inclined upwardly backward, positioning the second break at a suitable rotational distance below said horizontal bottom wall of the separator, and the lower section extending obliquely downwardly forward and having a vertical window for a second anchor screw disposed through a horizontal window made in a safety skirt which extends parallel to the bionde barrier, covering for the most part the height between it and floor ; in this arrangement, in the operational position of the plate, the lower section is in an oblique downward position which extends forwardly at an angle of 10 ° to the vertical.

Comme il ressort de la présente description préconisée, la fabrication de la platine selon l'invention est d'une grande simplicité, et de ce fait, de coût réduit ; il suffit de produire les encoches horizontales et la fenêtre verticale sur l'état plan de celle-ci et de réaliser ensuite les deux plis générateurs des cassures, avec des angles adéquats précis.As is apparent from the present description, the manufacture of the plate according to the invention is very simple, and therefore of reduced cost; it suffices to produce the horizontal notches and the vertical window on the plane state of the latter and then to make the two folds that generate the breaks, with precise and precise angles.

Comme souligné, la platine est adaptée pour être installée de façon opérationnelle sur une barrière bionde déjà implantée sur la voie. A cette fin, il suffit de desserrer la vis correspondante employée pour l'ancrage de la barrière bionde à l'avant du séparateur fixé au poteau ; ensuite, on fait glisser à l'horizontale la section supérieure de la platine sur la face du séparateur, de telle manière que la tige de la vis pénètre dans l'encoche supérieure au moment où la paroi inférieure du séparateur pénètre dans l'encoche inférieure ; et enfin, on serre ladite vis. Cette action pourra être effectuée alors que la jupe de sécurité est ancrée à la platine, ou cet ancrage pourra être effectué une fois la platine montée sur la barrière bionde.As underlined, the plate is adapted to be installed operationally on a bionde barrier already installed on the track. To this end, simply loosen the corresponding screw used for anchoring the bionde barrier at the front of the separator attached to the post; then, the upper section of the plate is slid horizontally on the face of the separator, so that the rod of the screw enters the upper notch at the moment when the lower wall of the separator penetrates into the lower notch ; and finally, said screw is tightened. This action may be performed while the security skirt is anchored to the plate, or this anchoring may be performed once the platen mounted on the bionde barrier.

Du point de vue fonctionnel, il est important de considérer l'inclinaison de 10° selon laquelle la section inférieure de la plat ine (à savoir, la jupe de sécurité) s'étend vers la voie. Ainsi, lorsque cette jupe de sécurité reçoit un impact, elle offre une capacité d'absorption progressive de l'énergie de celui-ci qui se traduit par la capacité de modifier de manière successive la trajectoire du corps impactant ; en premier lieu, la section inférieure de la platine réalise une course d'absorption d'énergie jusqu'à ce que la seconde cassure vienne en butée par dessous avec ladite paroi inférieure du séparateur de la barrière bionde, ce qui peut être suffisant pour absorber l'énergie d'impacts relativement peu forts ; si l'énergie du choc est plus importante, à partir de ce point, elle commencera à être absorbée moyennant la déformation jusqu'à la verticale de la section inférieure qui, en la surmontant, entrera en butée contre le poteau de la barrière bionde.From a functional point of view, it is important to consider the inclination of 10 ° in which the lower section of the plate ine (ie, the security skirt) extends towards the track. Thus, when this safety skirt receives an impact, it offers a progressive absorption capacity of the energy of the latter which results in the ability to successively modify the trajectory of the impacting body; firstly, the lower section of the plate performs a power absorption stroke until the second break comes into abutment from below with said lower wall of the separator of the bionde barrier, which may be sufficient to absorb the energy of relatively weak impacts; if the energy of the shock is greater, from this point, it will begin to be absorbed by means of the deformation up to the vertical of the lower section which, by surmounting it, will abut against the post of the bionde barrier.

Description d'un mode de réalisation préféréDescription of a preferred embodiment

En référence aux dessins joints et aux références précitées, nous allons décrire un mode de réalisation préféré de l'objet de l'invention concernant un bras d'ancrage pour un système de protection de motocyclistes applicable à des barrières de sécurité à deux ondes, ce bras comprenant, comme le montrent les figures 3 à 5, une platine 2 qui a un profil déterminé par trois sections qui sont reliées par deux cassures et qui, conformément à leur disposition opérationnelle, sont une section supérieure 3, une section intermédiaire 4 et une section inférieure 5, telles que les sections supérieure 3 et intermédiaire 4 sont reliées au moyen d'une première cassure 6 ayant un angle supérieur à 270°, tandis que les sections intermédiaire 4 et inférieure 5 sont reliées au moyen d'une seconde cassure 7 qui est réalisée dans le sens opposé à celui de ladite première cassure 6 et avec un angle supérieur à celui de ladite première cassure 6, la section supérieure 3 étant adossée à la face oblique et descendante vers l'arrière d'un séparateur 1a au moyen duquel la barrière de sécurité à deux ondes, ou barrière bionde 1, est ancrée à chaque poteau 1b de soutien de celle-ci, alors que sur un des bords latéraux de cette section supérieure 3, s'ouvrent à l'horizontale une encoche supérieure 3a et une encoche inférieure 3b, l'encoche supérieure 3a coïncidant avec un trou 1c existant sur la face du séparateur 1a pour une première vis d'ancrage 8 adaptée au montage de la barrière bionde 1, pendant que l'encoche inférieure 3b reçoit en son sein l'épaisseur d'une paroi inférieure horizontale 1d du séparateur 1a, la section intermédiaire 4 étant inclinée de façon ascendante vers l'arrière, situant la seconde cassure 7 à une distance 11 en rotation adéquate en dessous de ladite paroi inférieure horizontale 1d du séparateur 1a, et la section inférieure 5 s'étendant de façon oblique descendante vers l'avant et possédant une fenêtre verticale 5a pour une seconde vis d'ancrage 9 disposée à travers une fenêtre horizontale 10a pratiquée dans une jupe de sécurité 10 qui s'étend parallèlement à la barrière bionde 1, couvrant sur sa majeure partie la hauteur entre celle-ci et le sol.With reference to the accompanying drawings and the aforementioned references, we will describe a preferred embodiment of the subject of the invention concerning an anchor arm for a motorcycle protection system applicable to two-wave safety barriers, which arms, as shown by the Figures 3 to 5 , a plate 2 which has a profile determined by three sections which are connected by two breaks and which, according to their operational arrangement, are an upper section 3, an intermediate section 4 and a lower section 5, such as the upper sections 3 and intermediate 4 are connected by means of a first break 6 having an angle greater than 270 °, while the intermediate 4 and lower 5 sections are connected by means of a second break 7 which is made in the opposite direction to that of said first break 6 and with an angle greater than that of said first break 6, the upper section 3 being leaned against the oblique face and downward towards the rear of a separator 1a by means of which the two-wave safety barrier, or barrier bionde 1, is anchored to each support post 1b thereof, while on one of the lateral edges of this upper section 3, open horizontally a notch upper 3a and a lower notch 3b, the upper notch 3a coinciding with a hole 1c existing on the face of the separator 1a for a first anchoring screw 8 adapted to the mounting of the bionde barrier 1, while the lower notch 3b receives within it the thickness of a horizontal bottom wall 1d of the separator 1a, the intermediate section 4 being upwardly inclined rearwardly, locating the second break 7 at a suitable distance 11 in rotation below said horizontal bottom wall 1d of the separator 1a, and the lower section 5 extending obliquely downwardly forward and having a vertical window 5a for a second anchoring screw 9 disposed through a horizontal window 10a formed in a security skirt 10 which extends parallel to the bionde barrier 1, covering for the most part the height between it and the ground.

Les figures 1 et 2 illustrent clairement le montage opérationnel de la platine 2 qui soutient la jupe 10 de sécurité qui est destinée à palissader la majeure partie de la hauteur de l'espace laissé par la barrière bionde 1, dans une mesure suffisante pour que le corps d'une personne glissant sur le sol ne puisse pas passer sous elle. Comme on peut le comprendre, la section supérieure 3 (voir le détail agrandi sur la figure 1) est maintenue entre la barrière bionde 1 et la face du séparateur 1 a au moyen de la première vis d'ancrage 8, la même que celle utilisée pour le montage de la barrière bionde 1 elle-même ; de manière que l'encoche 3a coïncide avec le trou 1 c déjà présent sur la face du séparateur 1 a et que dans l'encoche inférieure 3b, soit logée la paroi inférieure 1d du séparateur 1a. On déduit de tout ceci que pour le montage de la platine 2 sur une barrière bionde 1 déjà installée, il suffit de desserrer ladite première vis 8 dans une mesure suffisante pour que l'épaisseur de la section supérieure 3 de celle-ci puisse passer ; et une fois qu'elle est correctement positionnée, il faut resserrer la première vis 8 pour terminer le montage.The Figures 1 and 2 clearly illustrate the operational mounting of the plate 2 which supports the skirt 10 of security which is intended to fence the major part the height of the space left by the barrier bionde 1, to a sufficient extent that the body of a person sliding on the ground can not pass under it. As can be understood, the upper section 3 (see the enlarged detail on the figure 1 ) is held between the bionde barrier 1 and the face of the separator 1a by means of the first anchoring screw 8, the same as that used for mounting the bionde barrier 1 itself; so that the notch 3a coincides with the hole 1c already present on the face of the separator 1a and that in the lower notch 3b, is housed the bottom wall 1d of the separator 1a. It can be deduced from all this that for the mounting of the plate 2 on a bionde barrier 1 already installed, it suffices to loosen said first screw 8 to a sufficient extent so that the thickness of the upper section 3 of the latter can pass; and once it is correctly positioned, tighten the first screw 8 to complete the assembly.

L'état du montage au repos est celui illustré sur la figure 1 qui montre que, dans la position opérationnelle de la platine 2, la section inférieure 5 se trouve dans une position oblique descendante qui s'étend vers l'avant en formant un angle de 10° par rapport à la verticale. Comme on p eut le vérifier visuellement sur cette figure 1, dans cet état de repos, la seconde cassure 7 est à une distance adéquate 11 en dessous de la paroi inférieure 1 d du séparateur 1 a ; de telle manière que, lors d'un impact, la section inférieure 5 de la platine 2 peut effectuer une première course de déformation et d'absorption d'énergie jusqu'à atteindre la position montrée sur la figure 6, et une seconde course qui est celle illustrée au moyen des positions intermédiaire (figure 7) et de butée (figure 8) contre le poteau 1 b. Cette fonctionnalité est favorisée dans une bonne mesure par le jeu d'angles de pliage donnés à la première cassure 6 et à la seconde cassure 7 ; elle a pour avantage de permettre une absorption progressive de l'énergie de choc et une modification successive de la trajectoire du motocycliste, réduisant les dommages physiques subis par celui-ci ; si l'énergie du choc est modérée, elle peut être absorbée par la déformation montrée sur la figure 6, et si elle est supérieure, cette première absorption sera suivie par celle relative à la déformation que montrent les figures 7 et 8.The state of the assembly at rest is that illustrated on the figure 1 which shows that in the operational position of the plate 2, the lower section 5 is in an oblique downward position which extends forwardly at an angle of 10 ° to the vertical. As we could verify visually on this figure 1 in this state of rest, the second break 7 is at a suitable distance 11 below the bottom wall 1 d of the separator 1 a; in such a way that, during an impact, the lower section 5 of the plate 2 can perform a first deformation and energy absorption stroke until it reaches the position shown on FIG. figure 6 , and a second race which is the one illustrated by means of the intermediate positions ( figure 7 ) and stop ( figure 8 ) against the post 1 b. This feature is favored to a good extent by the set of folding angles given to the first break 6 and the second break 7; it has the advantage of allowing a gradual absorption of the shock energy and a successive modification of the motorcyclist's trajectory, reducing the physical damage suffered by the motorcyclist; if the energy of the shock is moderate, it can be absorbed by the deformation shown on the figure 6 , and if it is superior, this first absorption will be followed by that relating to the deformation which the Figures 7 and 8 .
